Hi all,
I just purchased a used GT-I9100 after hard bricking my old one (Odin froze at Set Partition).
Anyway, this 'new' phone had stock 4.0.4 ICS and kernel, AND it had the insane chip. Thus, I immediately flashed the Siyah 4.1.5 kernel to it. Now, I want to update to JB. I should be safe to do so, right? Also, is there a guide to update directly to a custom JB based rom and kernel? I just need some reassurance after bricking my old S2
Thanks!

It should be fine if you have a safe kernel. Just boot to recovery, wipe data/cache and install the rom you want

Hey.
I'm looking to flash my pretty old Galaxy S2 from a custom GB rom to one of the spaking new JB roms.. the only thing is I'm not sure if my phone is updated enough to support flashing the new roms?
The particular rom I am looking at installing is SentinelROM v4.75
http://forum.xda-developers.com/showthread.php?t=2268064
The instructions say:
If installing for the first time:
To install this ROM you will need to have an unlocked bootloader and a custom Recovery such as TWRP or ClockWorkMod installed (personally I recommend TWRP, I have had issues with restoring backups using CWM).

What I currently have on my phone is:
CheckROM RevoHD V6
Baseband XXKI4
Android 2.3.6
N.E.A.K Kernel 1.4.2x with CWM v5.0.2.8
Am I good to just load the ROM onto my sdcard and just flash away or do I need to update my phone to a JB stock rom first? I'd ask this question in his thread but I don't have enough posts apparently..

Install directly 4.2.2 ROM,then do a factory reset
Hello and Good Day Devs !
I am kind of a newbie in the world of rooting (for samsung galaxy s2 gt i9100). So i just recently got my dad's permission to root and flash a custom rom on my device . I am currently using a samsung galaxy s2 gt-i9100 running jelly bean 4.1.2 XWLST . Am from India and i am highly confused. So i would like to know which kernel would be the best for rooting my phone (best i.e. safe , bugless) After rooting i am planning to flash a custom rom. I would Most probably flash the PACman ROm (jelly bean 4.2.2) and would like to know which kernel would suit the rom. rather i would like to know which kernel is supported by the PACman rom. i searched and read a few threads and concluded that siyah is a bit buggy causing a lot of problems . Philz is a good kernel but i also read that PhilZ's kernel is not supported by a few roms. I also checked out the 'jeboo" kernel and found out that it was somehow related to the PHilZ kernel and eventually backed out . So pease help me out devs .. any help would be appreciated and thanks a lot for your co-operation :laugh:
Whatever kernel you flash will be overwritten when you flash your custom rom.......every custom rom comes with its own kernel......
So the choice is yours......
Select your kernel and flash it however the instructions say, then flash your custom rom.....job done.....no issues/worries about incompatiability........

start with siyah kernel v6.0b5
It is the safest kernel to start with
Then flash pacman
It is your choice to flash a new kernel over the stock pacman kernel
You can flash whatever custom kernel you like and as @keithross39 mentioned dont worry about incompatibility
Use odin
Gud luck mate
The only time you have to think about kernel compatiability is if you decide to flash a kernel on top of your custom rom. As I previously mentioned, the kernel you flash to root your phone will be overwritten when you flash the rom, so no incompatiability will exist because you will have basically erased that kernel during the flash. But any kernel you flash on top of your new rom HAS to be compatiable or you'll end up with an unuseable phone......

Thanks A lot devs . I will now root my phone and flash the rom ! thanks a lot for your help!
Hi guys
I have the following isue, i flashed my phone and I used this kernel
3.0.31 siyah s2-v6.0b5+ [email protected] #177
Now I cant make calls, I can't hear the person who call me and that person can't hear me, the phone radio doesn't work, sometimes the phone freeze specially when I watching videos. The phone doesn't recognize all internal memory. The return and search button doesn't work, to go back now I have to press the home button.
My question is: can I flash the kernel i have installed and install a new one. What kernel do you recommend me for this phone that works fine and what rom 4.2 is the best for this model.
I really appreciate any help.

Your signature says your phone is GT-I9100, but this is the forum for SGH-I777 AT&T version of Galaxy SII. Which phone do you have?
I have an i777 from at&t, after i flashed the kernel the phone model changed from i777 to I9100, but it is an i777 from at&t

Did you flash only the kernel, or did you also flash a rom?
What version of the operating system, and what rom are you currently running?
The kernel you flashed was built for the GT-I9100, which has a different hardware configuration from the SGH-I777. You should flash a kernel that was built for the I777, probably AJK, but answer the above questions first before I suggest which one.
First I flashed the kernel and installed the siyah one, then I installed a different rom. I had before 3.2 and then I installed 4.1.2 rom. Can you recommend me a god kernel for the I777 and a good rom if it possible 4.1.2 or 4.2 . I really appreciate your help.

You appear to have flashed the GT-I9100 stock XWLS8 full package. Most likely you flashed the I9100 boot loaders with it. You also have an I9100 modem. I'm guessing that you flashed the I9100 siyah kernel afterwards. Your I-777 will not function with that firmware. I am surprised it even booted into system.
First, double verify that you are working with a SGH-I777 by pulling the battery and looking at the label in the battery compartment. After verifying that you have an I-777, you should flash the AT&T version of stock 4.1.2, I777UCMD8 full package which you can get from the download repository.
If you are unsure of anything, or have any questions, please ask before proceeding.
If you want to root and install a custom kernel, or install a custom rom, after getting your phone working again, we can point you in the right direction.
Thanks for your help, yes I verified and it is an i777 from at&t.
A have some questions:
1- I need to flash the kernel first and then install the new one?
2-can I install a 4.2 rom with the kernel you recommend me? I really like to have 4.2 on my phone.
3-how I get rooted after do that?

No. Flash the I777UCMD8 full package from the download repository first. It contains the complete firmware, including stock kernel, stock system, an AT&T modem, and the I777 boot loaders. You can do any modifications after you return the phone to full stock 4.1.2.
3-how I get rooted after do that?

I am answering this question next, because it is the next step after flashing the stock firmware. To root, you should use the Framaroot application which you install on your phone. Use the Aragorn exploit. If the latest version doesn't work, download and use an earlier version, like 1.4.2.
2-can I install a 4.2 rom with the kernel you recommend me? I really like to have 4.2 on my phone.

Once rooted, you should use Mobile Odin lite or Mobile Odin Pro to install a custom kernel containing ClockworkMod Recovery. With this stock firmware, you would use AJK v4.9 No Swap.
After downloading the kernel, open the zip file and extract the boot.img. Use that to flash in Mobile Odin. After flashing the capacitive buttons will not work, so immediately reboot into recovery and flash the full AJK v4.9 No Swap package in CWM.
4.1.2 is the latest version of stock firmware available for the I777. If you want the Samsung Touchwiz interface, that is the latest you can get. Anything available 4.2 and above will be AOSP based. You can look in the I777 Android Development forum and the I777 Ported Development forum to see what is available. They all flash from ClockworkMod Recovery.
Ok man thanks, I'll do that, after that I'll let you know how everything goes

Hello. I have a SGH-I777 on android 2.3.6 not rooted or anything. What is the correct order to do stuff to go to a custom newer rom? Thank you.
Please someone?

Take the OTA to the latest firmware for the at&t s2 which is Android 4.1.2 and then root it using the frama root app (just search Google for it). Once rooted pick a kernel to flash in ODIN or mobile ODIN. For AOSP ROMs I think ktoonsez kernel works and for touchwiz ROMs AJ kerwick kernel works well. I recommend flashing AJ kernel first as it works with the stock Samsung ROM.
Once you have flashed AJ kernel boot into recovery which will now be CWM recovery. From there you can flash shoStock ROM or whizz cat ROM (see my guide here in the s2 forums on how to boot i9100 TW ROMs) or any AOSP ROMs you like. Just make sure you have an AOSP kernel for AOSP ROMs and a touch wiz kernel for TW ROMs. Most ROMs come with a kernel though.
