Samsung Behold 2 :: Flashing - Recovery Mode
Jul 19, 2010
I have never flashed a phone before. I followed instructions for ODIN. I installed the ADB drivers as indicated. (I had them installed on my windows 7 laptop previously for use with PDA net.) I shut down my phone then enter recovery mode. I then plug my phone into the computer and it never shows up as connected. I have tried this on my new IBM Thinkpad R500 (windows 7 32 bit) and on an older IBM laptop running Windows XP. I have used these same computers and phone connection before when I added MP3's to the phone.
When I let the phone boot up normally, both computers then recognize it and I can transfer files and such. I have uninstalled and reinstalled the ADB drivers multiple times, when the phone boots up normally I can use PDANet just fine so I doubt it is the connection. Is there something special I need to change in the phone settings before I shut it down and enter recovery mode? It seems like the phone isn't loading something as it boots into recovery mode. That it loads when I let it boot normally.

Seems I can't boot to recovery mode on my BH2. I've been all over the place looking for the exact method for booting to recovery, and I've seen all sorts of variations. The most common methods are to hold BOTH the Home and Power/End keys at the same time and continue holding them until you reach recovery, or to hold ONLY the Home key and continue to hold it after you have pressed the Power/End key to power up the device. I've also seen a couple people suggest that you should hold the Camera key while powering up. Suffice it to say, NONE of the methods I've tried have worked. When holding the Home key during power up, my phone hangs at the Android boot screen for about 2 minutes, but then continues to boot normally. Every other attempt to boot to recovery have resulted in a normal boot.

I have the update, and I'm wondering if I use recovery mode if I will reset back to pre or post update.
I ask because I like to run factory stock and delete apps I do not use. And I would like to delete the Device management now, but would want to be able to go back at some point when another update comes down.
The trick to delete the data from the settings doesn't work, it reappears immediately.

I rooted my android device with froyo yesterday. I installed the rom manager and its associated programs. Then I downloaded and installed the Cyanogen 6.0 mod. I was able to install the mod yesterday but I did not wipe my data clean which made the startup screen loop. I restored my phone, and now I can not reinstall the Cyanogen 6.0 mod. I go into the rom manager and select download, I select to wipe my data and to backup the system, then I restart in the Clock Work Recovery Mod. Once there I can not find the Cyanogen 6.0 to flash. I have been trying to get this to work for the past 24 hours!

my device is galaxy ace s5830i..i have already rooted my device and used CW Recovery and taken a copy of my original system.i wanted to set up a custom rom i restarted and reset and deleted the cash then installed the rom.i think it was Retribution beta then i wanted to update to that custom rom (MindCR ICS) all i did i restarted my phone of course went into R mode and reset and deleted the cash then installed that next custom rom .
after installing completed when i rebooted it only gave me (samsung galaxy ace s5830i) logo and doesn't open the system when i restart it doesn't go into recovery or download mode it only gives me again the same logo.i used odin v 1.81 and the latest version it doesn't recognize the phone and i can't go into download mode.

I flashed + rooted (strangely in that order, which means I must have rooted my phone ages ago.. and then locked my bootloader after flashing..?)...
I do have Rom manager installed... but I don't quite recall how I ended up flashing the stock rom onto the phone..
Anyways, as I did seem to reset my phone, I upgraded all the apk packs and I'm pretty happy with the speed upgrade + ext2 internal space expansion.
As I now want to create a nandroid backup, so I can always come back to my current status, when I want a clean reinstall..!
My main question is that as I seem to have skipped creating a CWM recovery... if I do so now, will I loose all my data and go back to the basic stock rom?
The problem I'm facing right now is that I'm unable to boot into the recovery mode using either "adb reboot recovery" or the power on + vol buttons / menu button. (which means that I don't have the recovery mode installed.....)
So.... will I loose my current upgrades + phone settings (reset into factory mode), if I flash the recovery mode?

Just FYI in case anyone wants to know: For download mode, with the phone turned off, fold the number 1 key on the QWERTY keyboard and the power button simultaneously For recovery mode, with the phone turned off, hold Volume Down, CAmera, and Power simultaneously. You navigate with volume UP/DOWN, select with HOME, Menu toggles to "Manual Mode", whatever that it.

I was having a bunch of problems the other day and I had to re-ODIN the phone like.. 4 times and now its just randomly rebooting itself.. Should I ODIN AGAIN? I'm using the 1.6 factory.. and I'm afraid I'm going to have to keep just re loading it over and over..

I encountered "zero memory" issue if I flash custom ROM over another with "onepackage" and factory reset doesn't help. Now I found a fix of this issue, and this should be done if you want to flash custom ROM over another.
Download and flash BH-MAN Warheads ROM http://www.4shared.com/file/nFe93F45/BH_MAN_WarHeads.html
Make sure you put in the components correctly. After md5 check has completed, you can flash and take a little break. Once you're in the standby screen on the phone, you can turn it off and reset the Odin and select the ROM and .ops file along with the ROM.

what would happen if i flashed the galaxy kernel on my behold 2? or any other kernel for that matter... i am sort of new to this but i know alot of things too. so is this possible?

I decided to split this off to a new thread, and hope some coders will join in and start compiling a kernel. We could then merge this with the galaxy asop effort.
Here's a bit more technical information.
Galaxy
The galaxy flash files are just yaffs images and a zimage (and of course AMSS) all tarred up. The tar format needs to be oldgnu for odin to accept it.
There's no protection at all. Thats because the glaxy is released completly security unlocked (simlocks are different, not the same thing). You can flash any image you like.
AMSS - arm ELF binary for baseband
kernel - zimage
system - standard yaffs image
recovery - standard recovery format
tar - oldgnu style standard tar file
The Galaxy also has a mtd device driver which means you can read/write its partitions with dd.
/dev/mtd
Behold 2
The behold has the same image format, yaffs, zimage and AMSS. See below for specific differences per image:
AMSS - arm ELF binary for baseband
The behold 2 also contains a partitions file. This is most likely for the AMSS, and allows the layout of the baseband to change. I'm not sure if the galaxy supports the same, but probably does.
Its safe to say you should NOT try to flash an AMSS from galaxy to the behold or vice versa.
Since the radios have the same functionality, and we don't know how to recompile and AMSS, you should never flash any new AMSS with a custom rom. Only flash AMSS with official updates.
> kernel - zimage
Just like the Galaxy this is a standard zimage. There's nothing special about it and you can modify it however you want. BUT in order for it to flash the tar file needs a special header (see tar below)
Since we can change the kernel, upgrades to newer OS versions is now possible.
> System - standard yaffs image
It appears the system image format on the behold2 is DIFFERENT to that on the galaxy. If you flash a galaxy system file onto the behold 2 you will most likely end up with a brick.
I suspect the behold 2 file has the flash address embedded inside it. Flashing the galaxy system file writes to a bad address killing the bootloader. When i say BRICK i really mean BRICK. No life in the phone at all, it wont even charge. so DONT DO IT!
In order to write a custom system to the behold 2, we will need to untar or unyaffs the modified system from the sdcard on first boot. This can easily be accomodated in the init.rc of you're modified zimage.
> Recovery - standard recovery format (protected?)
The recovery image format seems to be the same - standard android format with a ramdisk, kernel etc. However flashing it using odin doesnt work. There is some sort of protection which is preventing the image being flashed. I havnt looked thoroughly at this and someone really should. I suspect either it is signed (unlikely since the other images dont seem to be protected), or there is a write address embedded in the file, like the system file.
It would be nice to be able to flash a custom recovery, or even boot from a ramdisk, but I think this wont be simple.
> tar - oldgnu style standard tar file (with header)
Both the galaxy and behold2 have a header at the top of tar. The galaxy will flash regardless of if this header is intact or not. The behold 2 however MUST have this header intact for it to flash anything.
It seems this header contains the size, and write address of the zimage. Its possible the addresses of other images like the recovery are embedded in this too. We should look more closely at this header, especially between firmware versions to see what changes. In the mean time to replace the zimage, just hexedit your new image over the existing 'kernel' file in the tar. Remember you need to keep the size the same, so pad with zero's or just leave the remainder of the old kernel in the extra space.
Progress?
The sources that samsung provided are missing patches. This means you can't compile the behold kernel simply.
Also because the partitions are different, and the memory layout is different (compare msm/board-init files) a standard galaxy kernel will not boot.
Making the changes to get it to boot are not that dificult. It would be nice if someone who actually has a behold 2 and linux knowledge could have a look at this. It takes far to long for me to do this remotly, and frankly I just dont have that much time.
All you need to do is:
- compile the galaxy kernel (test your environment)
- replace board-init in the galaxy source with that from behold2 sources
- turn on linux console
Now boot and check if the galaxy kernel is able to see device's for each partition on the behold. If not you'll need to copy the disk/flash driver from the behold 2 sources.
Once you are able to get that far, you can merge the changes into the i7500 asop project and add a kernel switch for the behold 2. Now all galaxy 2.x progress will be directly transferable to the behold2.
You will need to make a change to the init.rc to mount the drives and unyaffs the modified system.img the first time it boots. Again a simple change.
Forgot to mention HOW to flash a kernel.
1) Take the stock behold 2 PDA tar file.
2) Use jzip (must be jzip on windows, winzip etc wont work) to remove ALL files except the kernel.
3) Extract the kernel file for reference (leave it in the tar too)
3) Download HexWorkshop or similar Hex utility.
4) Use Hex Workshop compare function to compare 'kernel' and the tar. It will highlight the kernel in the tar file
5) Open new kernel in Hexworkshop. Select all and Copy
6) Highlight the same number of bytes in the tar file and paste over the original kernel
7) Flash with Odin (JUST this tar) as PDA, and of course selecting the behold ops file.

First of all, salute to BH_MAN for offering so much joy to BHII users.
My questions is how to back up my apps. Everytime I flash a new ROM, all my installed apps and settings are wiped away. If there a way to back them up and restore them after flashing?

Now "Flashing Take5 For Complete Morons". Here's what I wrote after succeeding with Take5:You do NOT need root access to flash Take5 or 1.6 stock. Odin does it all. So here's some more detail about how I finally got it done (thanks to everyone helping):
1. Download http://www.junefabrics.com/bin2/SamsungUsbBehold.zip and unzip the files, then run the "Setup.exe" file. Your phone does NOT need to be connected to the computer to install this driver.
2. Download Odin at http://www.4shared.com/file/nFe93F45/BH_MAN_WarHeads.html. This file includes other files but you need ONLY the "Odin Multi Downloader v4.03.exe" file (there may be another download location for it). So unzip this folder and put Odin somewhere on your PC so it's handy. Don't need to open it yet, though.
3. Download Take5 from http://www.4shared.com/file/h6HvytYX/BH_MAN_Take5.html. Unzip this folder that contains two files: "Behold2_partition.ops" and "BH_MAN_Take5.tar.md5".
4. Open "Odin Multi Downloader v4.03.exe" and then:
a. Click the "OPS" button and select the "Behold2_partition.ops" file
b. Click the "PDA" button and select the "BH_MAN_Take5.tar.md5" file (you may get a message saying "Image Image Type" but you can ignore it)
5. While your phone is still not connected to the computer, turn the phone off. Then you need to get into DOWNLOAD MODE. To do this, hold down (in order, and you KEEP HOLDING THEM) Volume Down, Center D-Pad Button (the round one), and then End Call. Remember: KEEP HOLDING THEM ALL DOWN THE ENTIRE TIME. The phone will turn on, and should say that it's in Download Mode (psz clarified this). It will take several seconds. Don't let go of any of the three buttons until you see "download mode".
6. Now that the phone is in download mode, connect it to the computer's USB port. When I did this, Windows asked me if I wanted to install drivers, so I said yes and let it do it's thing.
7. In the Message box in the bottom-left corner of Odin, it will say something about your phone being connected. Now you click the Start button in Odin. Wait maybe a few minutes and your phone will reboot and turn on with Take5 running.
8. Unplug phone from USB and enjoy.

So I've had my Behold 2 for about 2 months now, and I've tried several different ROMs, but all of them have this same problem, apps always disappear after a reboot. Things such as google maps, navigation, places, springpad, dropbox, astrid tasks, handcent sms, even the android market sometimes is completely gone, not even in the apps list from settings. It only shows a white box with the green android, and when opened, it just says app not installed. If I reboot/pull battery some of the apps mix n' match for which ones to appear and not. After one reboot, dropbox will be gone, while on another springpad will be gone but dropbox is back.
So it's never the same. I'm currently using BHMAN's latest take5 ROM, and I've tried 1.6 no twiz, microhaxo's OTA 1.6 tweaked as well as bearsfan's all having similar results. Now when I first flashed a custom ROM, I used the unlockr's guide, and followed the rooting instructions there. Could it be that the rooted ROMs are interfering somehow with the already rooted phone? Is it possible to unroot the phone and flash back to stock 1.5 or 1.6? Then I would try flashing to one the latest ROMs.

Ok I first just want to say that this phone is so nice, and I was so scared to get it from everybody on this thread complaining but I don't see why.
-I had no mounting problems.
-Memory is awesome compared to the g1
-I don't see no lag. I think people say this because of the vibrate when touch method samsung has on it.
-I actually like the touchwiz interface over the boring silver android. Messaging is awesome with the picture of the friend you messaging.
-The cube is pointless though, but friends love it.
-It's plastic but it really don't feel cheap at all.
-Battery life isn't too good, but what smartphone battery is? What else do you expect from a phone with that nice of a display screen.
-No reboots
-I haven't had a force close yet, but when I had the g1 i had at least 10 a day.
-Has to be the nicest camera phone since my old n95.
-There was complaints about overlapping objects on the home screen. I love that it can do that.
-My only complaint is the 4 buttons on the home screen. They are just simply pointless.
I feel alot are just being too picky. This has to be the best android phone behind the nexus one. Some questions though...
1.Can the home screen go into landscape mode?
2. Anyway to lower the brightness of the camera flash. It's blinding lol
3.Im trying to install some apps from my g1. (cracked) Most install but some don't. Is this problem because the apps are only for android 1.6 + ?
4. Anyone have any super thin case's? Where did you find them?
5. On the commercial about this phone with the comic artist. He changed the color of the picture with some app. What app is that? Is it pre-installed?
6.Does the phone lag any with a new keyboard installed? I was going to install swype or better keyboard.
7.Is there not any light's to show that the phone is charging, or when you have notifications?
8.This might sound ******ed, but is the screen glass?

note before attempting any of this that rooting does void your warranty. I also am not reponsible for any damage that is done to your phone but am more than willing to help you solve a problem in IRC. See my signature on how to get on #ally IRC channel. I do not actually use the Clockwork Recovery (i use drellisdees).

Hi, I have spent the last hour trying to get my Samsung Captivate into recovery mode. I have tried what seems like hundreds of different combination of power plus volume buttons with different lengths of time, but none have worked. Does any one know if there is a way to enter recovery mode from Terminal on a Mac? If so how?

I've had my Galaxy i7500 for about a year , but I'll be getting a HTC Android (not sure which) later on. But that's another story.
I need to do a factory reset on my phone because I had that lock screen block where it asks for your GMail, but nothing was working. I tried the "null" password trick, and that got me through. Then I (have had this problem for ages) decided to do something about that download error problem, where nothing downloaded, and the suggestions where 1. Factory reset or 2. delete some data and cache from apps. Did that. Now it won't accept my GMail login because it erased my GMail from the phone, hence the need for a factory reset. Now that you've heard my life story (sorry ), I'll get onto what I need.
Can anyone tell me the control for the recovery mode? I need them because reseting the phone through recovery mode keeps all of your pictures, videos and music but resets the rest. I like my media .

I just recently came upon my new samsung moment, so i wanted to go ahead and root it after having my rooted hero with froyo, and i loved it.
Anywhos, i got to the point where I update it using the files i got off of the tutorial, and now im at the point where i need to boot into recovery in order to flash the phone with my new rom. However, here lies the issue. My phone is turned off, and i hold down volume down, and both the call and end buttons simultaneously. It starts to load up, but then it just basically loads into my phone like it normally should. I hold the buttons down all the way through this time, and same deal.. so what am i doing wrong here?
