So I was under the impression that you could use ROM manager or ClockWork mod to install a custom kernel that I had downloaded to my SDcard. I downloaded a low-volt, overclock kernel and I have discovered that I don't quite know to flash it to my phone.

So I've been looking into flashing custom kernels, and I can't seem to find an answer to this question. Basically, I'm wondering if the kernel remains after installing a new nightly, or do I have to reflash the kernel every time the ROM updates?

(this appeared before when phone was in stock state).Is it possible to do it without re-flashing to stock?
...or i have to put back the phone to stock? What is the easiest/safest/best way to do this? using the restore option in "PC companion" SE app? Is it only needed to put the stock kernel and ROM, or Do i also need to re-lock the bootloader?
I don't need the whole explanation, just a little guidance, just a few tips to know what to do, then i can google/search myself for the specifics on how to actually do it.

View 3 Replies View RelatedSo I rooted for the first time today, and tried to install Hydra Kernel's #1 & #3 kernels. The system seems completely stable with each kernel, except when I open the Camera app, the camera view is completely blank. Almost as if something was blocking the lens. Then when I try and take a photo, it locks up. I tried closing all apps, and restarting the camera, but this didn't work. Once I run a Nandroid restore prior to installing the kernels, the camera works fine.

View 2 Replies View RelatedI recently rooted my Evo using UnRevoked 3.2 and flashed Fresh 3.3 on it. I'm generally happy with the results, the upgrade seemed to fix some problems with random reboots and screen locks I was having on stock (I'm thinking that moving a lot of apps to SD may have helped, as I seemed to be always low on memory).
In any case, I do think the phone is a bit "laggy" after the update. I downloaded FPS2D and checked my FPS, seem to average right around 50fps with std dev of 9. It seems like many people are getting much better screen performance using the custom netarchy 4.1.9 kernel. I'd like to give that a try but I have a couple of basic questions...
1. I will do a nandroid backup and Titanium before I flash, but I noticed that restoring apps last time was a drag...I use FolderOrganizer and it's a pain to get them all set up the way I had them. Does flashing the kernel wipe your phone clean? How much app/Sense restoring would I have to do assuming all goes well? I'm assuming that flashing the kernel has little to no effect on installed apps or Sense screen layouts...he cried hopefully...
2. I'm assuming here that Fresh 3.3 is compatible with netarchy 4.1.9, correct? Also, I saw an indication that netarchy 5.0 may be around the corner...is it better to wait? Or is reflashing a kernel that easy so there's no reason to wait?
3. It looks like an overclocking app is included in the netarchy kernel? Is it necessary to tweak the profiles, and if so what are the recommended tweaks for best performance? I have some experience with this coming from an overclocked Palm Pre, but I care a lot more about my Evo...I don't want to hurt it!
4. Battery performance is less of a concern than screen performance for me...I have chargers everywhere. Still, I'd like to get the best battery performance I can. I believe there may be "rogue" services on my phone that are eating up the battery (for example, I use Exchange ActiveSync and I turned it off recently because sync problems were causing it to stay on in the background). What's a good way (or app) to identify rogue apps/services and kill them?

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?
View 3 Replies View RelatedI 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.
Do most people always backup the ROM, w/ ROM manager before installing new kernels?
Also is there a way to set the number of backups you keep w/ ROM manager?

I just went through the process of compiling a custom ROM and they used a stock kernel. I would like to incorporate a different kernel when I compile and instead of the stock. I know I could compile them separately and have them flash together but I want one zip to flash. Just would like to go through the process to learn.
what I have to do when compiling?'
When I got my phone at the end of last year I rooted it using a Chain-Fire kernel - v 4.2, I think. After flashing, it worked perfectly, since when I have flashed the old bootloader to get my USB Jig working to remove the yellow triangle and flashed a patch again to allow the USB Jig to reset the binary counter.
I have very much wanted to install and get the new Sky Go application working.
What I had to do was flash the Stock kernel for my Stock Rom - I have never messed with my Rom - it is Gingerbread 2.3.4 in a CPW phone here in the UK.
Doing the flash and installing Voodoo OTA (to temporarily hide my root) has been enormously successful
Now then to my query....
The original Chain-Fire mod v 4.2 installed CWM.
After of course cancelling the "hide root" function to show my phone as rooted once more, I went to do a backup, using CWM but it refuses to work. It says my kernel needs v 5.0. Obviously the Stock Rom I flashed to get Sky Go working has thrown CWM some what.
I have downloaded Rom Manager from the Market but this seems not to work either - it starts to work (reboots) but then halts with the following messages: -
E : failed to verify whole-file signature
E : signature verification failed
Installation aborted
What I would like is some way of installing a backup previously made before flashing the Stock kernal and also to make a fresh backup now.

View 1 Replies View RelatedI've had my Droid for a while and finally decided to take the plunge and root it a few days ago. I had initially updated with a Simply Stunning 2.1 ROM, and it went well and was beautiful. I was tempted by the siren's call of Froyo, however, and decided to flash Bugless Beast 0.1 onto my Droid via ROM Manager. I've seen in multiple threads that this is supposed to have Flash and WiFi Tethering native, built into the ROM. Mine, however, did not seem to install these features.
Are there multiple "BB 0.1" releases, and could ROM Manager have grabbed one that did not have these features? I've already grabbed a program to do the WiFi tethering, but Flash is one of the things I had heard worked with this release. Should I reflash the phone? I'm hoping to avoid that as I ended up using Metamorph to apply a really nice theme for it, but I didn't think to check for Flash until I was on a site that uses it and it didn't work.

View 49 Replies View RelatedI rooted my phone using Universal Androot (worked perfectly) and then proceeded to install ROM Manager to flash a custom ROM to my Ally. I used the Flash ClockworkMod Recovery first (sucessfully) then used Backup Current ROM to backup the stock (V8) ROM (sucessfully). I then proceeded to install the Velocity 0.1.1 ROM (sucessfully).
I've searched here a bit, and am unclear as to the process to restore my stock ROM using ROM Manager. I believe it would work as follows?:
Use Manage and Restore Backups. Select backup I made, and then restore.
If I wanted to un-root, I could then just use Universal Androot to un-root the phone (although I havent tried that part yet).
Love the ROM, just curious how to go back if I need to.
I rooted my stock 2.2 Evo a few days ago and have been loving CM6 on it. I had Clockwork Recovery 2.5.0.1 installed and finally got used to using it. I read that ROM manager was a nice graphical interface to CWR so I went to check it out. Unfortunately I couldn't do anything at all in it. Every time I tried to do anything it said I needed Clockwork Recovery installed. This confused me because it already was installed.
I would try to install it anyways, I would select "Evo CDMA" and then it would fail every time. I decided I would try to install Amon-Ra instead, and then just flash back. ROM Manager was able to flash Amon-Ra easily, but now still gives me an error every time I try to install Clockwork. I'm still new to the whole rooting scene and this is the first problem I've run into. Also, I already tried Fixing User Permissions.
