[Q] Flash Stock Kernel and Retain Root - Galaxy S III Q&A, Help & Troubleshooting

I have firmware XXBLFB (rooted) and have installed a custom kernel which I no longer wish to use. I would like to restore the stock kernel which came with this firmware release. I know I could just ODIN the BLFB firmware back and then re-root but it seems a long way to go. Is ther a way to use mobile ODIN with the firmware file to install Kernel only and retain root?
Thanks.
(Yes, you're right. I SHOULD have done a nandroid backup first!)

[Q] rom/kernel/android version/baseband question

So i got my sgs2 2 days ago and i rooted it with cf root . my stock vers was bvkg2 so i flashed xxkg2. afterwards i created a backup in cwm. then i flashed in darkyrom2 the wrong xxkg3 rom zip and it was ok except that the pc usb didnt read the phone well. so i resfored my backup in cwm and then flashed the xxkg2 odexed r2 or 3 . now my baseband version is i9100xxkg3 ,kernel is xwkf3 ,android 234 and firmware is darky KG2 odexed base r3. But cwm app was gone after ROMing. do i need to flash another kernel or is everhThing ok ? Th
anks
Sounds all fine.
The CWM app is installed by CF-Root and the ROM you flashed doesn't contain it.
So everything's cool.
If you want that app back, flash CF-Root again, if you don't need it that much you're set
Well I guess I'll be needing it for recovery? I see DarkyROM2 has recovery mode option but i don't see a backup option . Can you recommend a backup program or shall I flash CF-Root back on ?

Anyway, you must flash a CF-root kernel and after that install Titanium Backup in order to do a reliable backup.
1. Just flash any CF-Root ? Or XXKG2 ? Won't there be a problem if i flash it over 2.3.4 ? and how do i flash it , like the first time with Odin or in DarkyROM2 Tool flashing CWM zip ?
2. Why doesn't my PC see my phone in USB with DarkyROM ? I installed Kies back on ; was that wrong ?
Thanks again

[Q] Updating to KG5 via kies from 2.3.3 KF2

hello, i recently bought a SGS2 and i was just wondering, if i use kies to update the current XXKF2 kernel to the new KG5 one (also jumps from 2.3.3 to 2.3.4 right?) will this process factory reset my phone? will i get to keep my current layout of apps and cellular operator settings or is it all gone?
oh, i forgot, is there an insecure KG5 kernel yet to root with?
Hi! I really dont know if it will reset the phone but if its just the kernel it should no change it. I would recommend you to do a nandroid backup (google) with clockwork. There should be an insecure kernel, after the backup update it. Then root it go into clockwork - advanced restore and restore ONLY DATA. This should work.
Note: if you need the insecure kernel please tell me the build version i'll provide a link.

Kies does not update a kernel its a full firmware update .
Kies updates do not normally wipe the phone but you should have a backup .
jje
Scratch that, kies is being stupid and wont connect to the server so i cant update this way anymore, but i guess i can still use odin, im just not sure what kernels to use for the update and what kernels to use for the root, there are so many threads about this, im just getting more and more confused lol.
im currently running:
baseband:XXKF2
Kernel:XXKF2
Build:XXKF2
i'd like to update to the latest root-able firmware,
so if you can provide me with the link need i will appreciate it,
from what i gathered i need to flash the updated stock files, then flash the insecure files, the reflash the updated stock to remove the yellow warning sign, i think.
thanks.

Hi! Link to download nearly every version you want: samfirmware.com register, its free. Cilck toolbox (upper right corner) firmware then android. Select galaxy s2 and download the package of your choice. (stock kernel will be in the package too)
I am new user so if you want the rooted kernel links for kg5,... Please pm me
Hit me up for any other questions !

And yes, you're right. Backup, stock firmware flash, restore data, root kernel flash and stock kernel flash.
If you are doing this with odin your data will be wiped so a backup is needed.

CWM recovery question?

So let me see if i understand this correctly. From what i have read, it looks like i cant install CWM recovery without installing a custom Kernel? So me backing up my stock set up is pretty much out of the question? So everytime i wish to install a different custom rom i am essentailly reinstalling CWM recovery as well?
How can i backup my stock set up and restore it if i screw something up, or install a rom that i am not happy with? I am coming rom an epic 4g on sprint and it was different with that galaxy phone.
Flash a CF Root kernel that matches your firmware, create your near stock b/u. This will be your point to fall back on. 99.99% of ROMs you flash will include a kernel, that also has CWM, it may be a different version but they all work the same, for the most part. The majority of kernels include CWMr 5 or higher.
You'll always have the option of restoring your "stock" b/u so long as you don't delete it. Titanium b/u is the ticket to back up all your apps and their data rather than having to extract those apps/data from a CWM b/u.
You only have to root once. The easiest way to unroot is to flash a stock firmware. Flashing a stock kernel back on after you've rooted will replace CWM recovery with stock recovery, but you'll remain rooted. Probably doesn't address all your questions, but you've got a start.

forgot to mention that i am rooted now. using oneclickroot.
Just flash a custom kernel with CWM recovery installed inside.
Such as:
- Siyah
- Phoenix
- Ninphetamine
etc...
DO NOT FLASH STOCK KERNEL AS IT WILL DELETE CWM RECOVERY. ROM MANAGER DOES NOT INSTALL RECOVERY ON YOUR PHONE.

is it as simple as using Odin, clicking PDA and flashing the downloaded kernel? and there should be no side effects from using a custom kernel such as Siyah?
Getting back to 100% stock is easy, odin flash a rom.
CF root *is* the stock kernel, just with some bits added (CWM recovery and root).
CF root with your stock rom is defo the safest bet.

Yes if you get the kernel in odin tar file, otherwise flash CF root and use CWM recovery to flash the zips.

[Q] Back to GB 2.3.4 from ICS 4.0.3

I have my S2 rooted running Resurrection Remix Pro v1.1
Baseband i9100ZSLPE
Android Vers 4.0.3
Kernel version 3.0.15-i9100DXLP7-CL233393 [email protected]#3
However, I cant get SkyGo to run as it is not compatible with ICS.
I have downloaded the following rom: I9100XWKI4_I9100XEUKH2_EUK.zip
It contains the file : I9100XWKI4_I9100XEUKH2_I9100XXKI1_HOME.tar.md5
Can I install this using ClockWorkMod in recovery mode, or do I have to use Odin??
The reason I ask is that Voodoo Rootkeeper apparently does not work with phones updated with Odin, therefore if I can update using the zip file and CWM, that would be better for me as I will be able to root or unroot as required.
Thanks
Kieron
That's an Odin flashable file. Doubt you'll find many (any ?) stock roms CWM flashable. Flash the stock rom with Odin, then re-root your phone by flashing a matching CFRoot kernel. Piece of piss
Do you need a stock ROM? Can you not just flash a Gingerbread ROM in CWM?
If you didn't flash a pit file via Odin then you should be able to flash via CWM as long as the firmware is a CWM flashable copy.
Otherwise the .tar and .tar.md5 files can be flashed via Odin or mobile Odin.
Would have been a lot easier if you made a CWM backup of your GB firmware before installing ICS. Could have just restored and away you go.
Good luck.

Firmware I9300XXLFB backup

good morgning guys ,
i bought a S3 some days after lunch from my O2 provider.
one bad thing is, O2 uses a branded firmware.
i searched xda for threats with original firmwares, but i can´t find my version.
I want to use a custom firmware or try some one.
but i feel bedder, if i have my original version as backup.
that means all three files, csc, phone and pda.
at the moment i think about some roms like:
- CM9
- CM10
- Lite'ning ROM v1.0 - Fast as Lightning
So, i think the best kernel will be SiyahKernel S3 v1.5.1.
one solution will be to backup with titanum backup. i bought the licence, but this requires a rooted kernel, i don´t flashed yet.
I thougth about, but i want ti do it first, i have all 3 files at home.
can anyone help me?
greetz,
ravn83
use this program to download your stock firmware.
root your phone with cf-root, flash cm9/10. test it out.
when you wanna go back to stock, use triangle away, wipe everything in CWM and flash your stock firmware back with odin.
If you get messaging app errors on boot (usually happens when you go back to stock from cm) you will need to flash your CSC in the corresponding section in Odin and wipe in stock recovery.
