Nov 15, 2012I did a research regarding Flashing Kernels and Roms and currently i have installed Cyanogen 9.1 for my device.
1.Will I be able to update my phone and bring back to old ICS firmware via SUS once i brick my phone(I have already unlocked the bootloader via fastboot method)?
2.Evrytime when i flash the Rom(say CM9) i used to flash kernal(boot.img) for the respective rom.Is this necessary all the time? Will i able to flash a GB rom on ICS kernal(I am afraid to give it a test)?
3.Regarding CM9.1 which i have installed ryt now,I am satisfied with the performance,but i want a stable ROM wud make me happy with a better battery life unlike CM9.1. Any GB/ICS ROM which wud have a stable performance with descent battery life.
4.After using GB for a long time,i was very much addicted with the Phone pad kinda keyboard,but when ICS came into picture everything vanished,Smartkeyboard Pro is no gud,Touchpal is conjusted,i want the exact GB keyboard in ICS.
Phone: Xperia Ray
Bootloacker:Unlocked
ROM: GB Stock Rom
General :: Flashing Custom Kernel After ROM Update?
Oct 23, 2012So 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?

Feb 25, 2012When 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.

Jan 2, 2014I have an xperia X8 with some naa kernel and xperiadroidx 6.1.The thing is that with this custom kernel and ROM when i put a SIM from another network carrier, the question asking for the SIM-unlock code input is not showing up. (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.

Aug 29, 2013I'm interested in purchasing a Nexus 4 I have no cellphone plan, nor do I want one; instead I intend to use the phone as a tablet or PDA.
I would like to hear some feedback on how feasible it is to low-level remove the cell and gps antennas' capabilities. Is there a driver or kernel module of some sort that could be removed to 'neuter' the phone? Can the hardware run the antennas without the ROM or kernel's consent?
I've already read about the code to reach a developer menu and 'disable radio' as well as 'airplane mode'. Neither of these fit the bill, I want the phone to be incapable of transmitting cell/gps information.

HTC EVO 4G :: Flashing New Kernel Over Fresh 3.3
Oct 5, 2010I 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?

View 3 Replies View RelatedSamsung Behold 2 :: Flashing Kernel And Security ?
Feb 15, 2010I 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.

Oct 26, 2012I am in a development team which develops an app used by millions of users worldwide. We get mysterious crash log messages all the time which happens only a couple dozen or even less devices which we can not directly reproduce while the vast majority of the users can use those features without problem. We suspect that in some of these cases some custom ROM or custom kernel causes the problem. Currently we get these informations from the hardware/software environment (in the parentheses there are examples from an actual crash log):
- Android version (4.0.4)
- Board version (SPH-D710)
- Brand (Samsung)
- System build number (IMM76I.FH13)
- System build ID (IMM76I)
I have a Nexus S with ParanoidAndroid, and on the About Phone page there are the extra fields I speak about (for example CyanogenMod version, ParanoidAndroid version, kernel version). My question is that is there an universal way to extract all or some of this information which could work on any device?
General :: How To Update Kernel For HTC Phone From 3.0.16 To 3.0.61
Jan 30, 2013I am trying to update kernel fot HTC phone from 3.0.16 to 3.0.61 , as far as i know the theoretical procedure should be:
1) revert 3.0.16 to 3.0.0
2) update 3.0.0 to 3.0.61
and compile
my problem is wen i try to revert the patch with:
Code:
patch -i /pathtopatch/patch-3.0.16 -R -p1 --dry-run
it give me:
Code:
....
patching file drivers/tty/serial/pch_uart.c
patching file drivers/tty/serial/pxa.c
patching file drivers/tty/serial/serial_core.c
patching file drivers/hid/hid-core.c
Hunk #1 FAILED at 1340.
1 out of 4 hunks FAILED -- saving rejects to file drivers/hid/hid-core.c.rej
....
and
Code:
............
patching file drivers/usb/class/cdc-acm.c
patching file drivers/usb/class/usbtmc.c
patching file drivers/usb/core/config.c
patching file drivers/usb/core/devio.c
Unreversed patch detected! Ignore -R? [n] y
........
i think it is because HTC patch those files before. What those two fail messages means? and what is the right procedure to update kernel
General :: Built A Custom Kernel For Phone
Apr 26, 2012I'm trying to make a custom kernel for the Samsung Gravity SMART using sources from the unofficial CM9 port for the Gio/Ace (which both use very similar hardware to the Gravity Smart). What I've succeeded at so far:
1) Acquiring the source, both for the CM9 kernel and for the stock Froyo kernel
2) Searching for the device-dependent references in the stock kernel
3) Porting those changes over to the CM9 kernel
4) Getting everything to actually compile
5) Acquiring the stock CM7.2 source
6) Creating device makefiles (i.e. BoardConfig.mk, etc)
7) Building CM7.2 using kernel built in step #4
8) Putting the various img files into an Odin-compatible .tar.md5
9) Actually flashing to the phone.
And for all that work, I got.. a soft-bricked phone (fortunately, I have an Odin file for stock firmware). The phone boots to a SAMSUNG logo (not flashing/throbbing). how the heck do I figure out what's actually failing? Is there a bootloader to unlock, and if so how do I unlock it?

General :: Heimdall - Download Kernel Image From Phone
Nov 25, 2013I recently started experimenting with the Android kernel. I downloaded the 3.0.31 kernel (because I wasn't able to find the sources for my stock one: 3.0.31-889555) and built a kernel image (zImage) successfully.
I plan to use Heimdall github.com/Benjamin-Dobell/Heimdall to flash the kernel image on my phone (Samsung Galaxy S2 GT-I9100) but before I do this I would like to download the current kernel image from my phone.
Since heimdall is capable to flash the current kernel image, I guess it's also capable of downloading the current, is it?
