Samsung Behold 2 :: Zero Memory After Flashing Custom ROM

Jul 30, 2010

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.

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.

Samsung Behold 2 :: Flashing Kernel And Security ?

Feb 15, 2010

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.

Samsung Behold 2 :: Need Flashing Warheads For Complete Morons

May 15, 2010

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.

Samsung Behold 2 :: Flashing ROMs - Applications Always Disappear After Reboot

Oct 4, 2010

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.

Samsung Behold 2 :: Phone Resets On Its Own Now Cannot Find Memory Card

May 31, 2010

Sso yesterday, my phone did one of the resets on its own, thinking ok whatever (since its the norm now). When it came back up was saying please insert external memory card. Something like that. So again, its crapped out another card. I would have to check my last post to see if this happened with the old phone or the replacement. Its been just fine, now everything is gone again. I know I should back things up but when u have never had this problem b4 its not something that I always remember to do. I had removed weather widget and beautiful widget as I didn't know which one I wanted and was rearranging icons. Now I cant use either. I was checking for a schedule online.

Samsung Behold 2 :: Cant Use Stock Apps With Custom ROM ADB

Sep 9, 2010

I'm using Bearsfan85's custom ROM, but have lost the voice dialer app that was in the Samsung's touch wiz ROM. As this is helpful to avoid car accidents while on the road, I was hoping to get it back. I have the .apk file but ASTRO file manager won't let me install it. I've tried to adb push it but I get a "read-only file error". For whatever reason, the commands "adb remount" or "adb shell sysrw" aren't being recognized, which I think is what I need to do to adb push the voice dialer back onto my phone.Unless of course, the Samsung apps just aren't compatible anymore.

Samsung Behold 2 :: Creating Custom ROMs / Backups For Odin

Mar 18, 2010

Here is a brief much more complete guide to creating your own Odin images for distributing custom ROMs or making backups. Thanks to kam197, BH_MAN, chadmd23, SoulCreator, and all the other community members.

Requirements:
A Samsung Behold 2 to backup/edit/test ROMs on
Root via try3/asroot2, persistent su, or modified kernel
Working ADB connection
SD Card with ~300MB free
Cygwin - if you are working in Windows
Basic knowledge of a command line

Making the ROM Dump: The Behold 2 has 14 partitions in its flash memory, but only a few of these are useful to modify. You will want to focus on different partitions depending on what you want to do. After you make a ROM dump you will need to package it using the instructions in the following section before you can flash it. Backup your personal data? You may want to backup your data while trying out a different ROM. It is simple to do. Start an ADB shell session and obtain root access. Run the following command to dump the UserData partition: Code:
