Unknown kernel and now soft bricked - Galaxy S II Q&A, Help & Troubleshooting

Hi there, wasnt getting too much response in the Aus thread so fingers crossed someone can help. My dilemma is i have tried to root the phone and now im stuck on the opening screen...tried various kernels with no success. I dont have/ didnt check the original settings (hindsight i know)
Phone was on Gingerbread 2.3.5
Model is: 9100T - Vodaphone Australia
I can access the download screen, Odin works fine, kernels say pass/ success but my problem remains
I've searched countless threads, used just about every kernel, but unsure as to what the next step is
If anyone can shed some light on this matter it would be greatly appreciated.

did you try flashing a stock rom through odin ?

http://www.sammobile.com/firmware/, here you can find all stock firmwares for all carriers and countries around the globe... and yeah, you could flash gingerbread stock or you could even upgrade to ice cream sandwich.

You can pick whatever firmware you want, branded or unbranded wont matter, just download the one you prefer and flash it through odin (PDA)

Don't use Kies, use Odin, it's far less temperamental. Just download th XWKE2 firmware from samfirmware.com and flash in the PDA section of Odin

I have installed an unsecure kernel in my galaxy s2 (GT I9100G) but since I cannot find the original stock kernel, I wanted to roll back to the stock android version that came with s2 and thus wanted to know how could I re-install the firmware from KIES.

You need to reflash stock using ODIN before you can use kies, as Kies doesn't recognise custom kernels.

Will reflashing bring back the stock kernel and make the phone unrooted in short make it the way Samsung sold it to me?
Also, I am using Galaxy S2 I9100G build number GINGERBREAD.XWKJ2 and for it only 1 unsecured kernel was available at this thread - http://forum.xda-developers.com/showthread.php?t=1327509
I rooted my phone without any problem but since there's no way to get back the stock kernel, I am afraid that if need be, how am I gonna claim warranty for my device.

Yes aslong as you flash the firmware that came with it t will be like as samsung sold it. Have a look at intratech's thread he may just have the kernel if you still have the original firmware on it already.

Yes, I do have the original firmware on it. Didn't have enough guts to play with custom ROM :/
I did check intratech's thread and found stock kernel for XWKJ2 but the thread titles says "Official i9100 Firmwares" whereas my phone shows i9100G. I guess this won't work.
And, when flashing to original firmware, will the kernel's be replaced to the original one's as well?
Thanks for suck quick replies Am just a n00b diving into Android
You can extract the original kernel yourself if you want it http://www.hotfile.com/dl/136857418/c144909/I9100GXWKJ2_I9100GODDKJ2_INU.zip.html

Downloaded it. Now what do I do? Flash s2 with this, backup using titanium, root device and then use the stock to get rid of yellow triangle? Am I missing anything?
Thanks for your help
BTW, is there a way to get the latest available firmware in my country/region via KIES so that I can be 100% sure of being in right place
i cant post the link right now but you can google

Stock S2 Rom for ICS update

Hi!
I currently have my s2 rooted and on CM9. My phone is/was the european version GT I9100. I know that region is getting the ICS update on 3/10. Can some one direct me to copies of a stock rom that will be receiving the update?
Thanks in advance!
Since you have already flsahed your phone with CM9 why not just flash the official ICS when it comes out?

If your referring to

If unofficial or customized firmware is installed in the mobile, unexpected problem can happen during upgrading"
Thats why I want to go back to stock.
They don't expect you to flash the firmware via CWM or Odin. I don't think it will be necessary to flash a stock rom first

wouldn't it be best to wait before flashing the official one through kies mate. cause you are only going to after a few days when all the custom official ones be released going to root your phone again. i was thinking the same but i am going to hold off for a while

I can think of 2 possibilities why it might not work.
-wrong CSC: find your country's CSC and change yours to match. Here and Here
your ROM must have your CSC or a Multi-CSC where your CSC is included.
-"Zombie"-ROM: A ROM patched together from different originals, e.g. a good stock kernel from one ROM with a good modem from another ROM. This shouldn't be, because you took an original from intratech's Thread. But if you want, you can also try this.
I hope this helps.

It looks like you already have an ORANGE-ROM. what exactly are you trying to do? If you want to get rid of the orange branding, what you have there looks good.

[Q]Update to ICS

Good Morning Everybody, i just yesterday buy one Samsung GS2 and it have I9100XXKI4 Base version i saw many manuals to update it to ICS but my question is what version i need to chose is mater if i chose etc this "I9100XXLPH" and is different than my?
hi mate, ill be brief because its just about my bed time
I9100XXKI4 is gingerbread, I9100XXLPH is ics. So they wont be the same if your upgrading from gb to ics.
Are you wanting a custom rom or stock samsung?

I want Stock because of guaranty, so any manual to just take the stock ICS Rom?
and what CF-Root i need to use? i mean version!
you do know when you flash cf-root via odin your going to increase your custom counter and in effect void your warranty, so youll need to either use a usb jig or use chainfires triangle away app?

yes, everytime you use odin to flash a rom on your phone you increase the custom counter by one, if this is not set to 0 ( zero ) your would lose your warranty if you took it to a samsung store for repair. So when you flash ice cream sandwich on your phone, theres an app called triangle away by chainfire ( play store ) which will reset it back to zero and your warranty will be ok! but only use it on ics not gb.
when you tell me your location ill post you a link to ics for you ( stock ) and the cf-root file and the instructions to use it. You have flashed a phone with odin before?

My guess is you have an firmware for a different country and need to install the CSC for your country.

[Q] Newbie --India --Three Network mobile -- Basic Questions

Hi All,
I bought a used galaxy S2 I9100 yesterday,new to android.I have been a iphone user for 4 years and pretty aware of jailbreaking, unlocking installing custom firmwares. the terminology here in Android world is different though.
Have searched and read through different guides on the forum but still got some questions.
Model GT i900 LKAH3G
PDA i9100XWKE1
CSC I9100H3GKD4
Kernel 2.6.35.7-I9100XWKDD-CL161513 [email protected] # 2
Build Number GINGERBREAD.XWKE1
Looks like it was on Three network but it is unlocked mobile as i can use my airtel sim on the phone.
I dont want the Three network related stuff on the phone so i need to debrand the phone -- how to do it? there is guide on XDA forum but it talks primarily for O2 phones or might be i did not read it correctly. (there are also some options like the network mode which are disabled on this ROM )
Once debranding is done should i be ok to use any ROM or kernel?
Which would be best ROM to be installed and will it work for me in India.
Can i install the custom ROM and would i be able to install apps from the android Market.
If these have already been answered , can you please provide the link for that thread.
Thank You
I'd advice you to try the new ics roms, you can find the instructions inside the various rom threads, flashing these roms will get rid of the three junk as well as update your phone to the latest android os a.k.a ICS ..........
there is no such thing as a best rom for a specific country, but you can try different modems to find the one that gives you the best network and battery, you can find your modem under the baseband in about phone....
google for more info
happy flashing and welcome to Android we luf you here...........
Learn how to use Odin
Download stock gb from from checkfus or sammobile.
Flash using Odin, you will be unbranded.
After that root using cfroot, now learn how to use cfroot.
Now you can flash custom roms.

Thank you for the details.

do i need to change the csc if i install the UK version?
Thanks
forget about csc.
if you have i9100 you can flash any region ROM and use in any country.
if you want Gb than go for la2 italy rom , iv used that and last time i check that was the fastest stock rom for GB
you can also flash ICS rom like uk lp7 too, just stay away from lp9 roms at the moment.
ad dont forget to wipe using the dialpad code *2767*3855#. [will wipe all data stored]

I have tried to do a factory rest from the phone's privacy menu but even after everything is done,istill see some files in the gallery.
i tried the code *2767*3855# everything goes fine but i see the message "cant access to system\csc\h3g\system\" and then the phone strats as normal.
can i flash it to the OS even if i am getting this message using odin or do i need to
do something before i flash?
factory reset will not delete your user stored data on the SD card...that can be manually deleted...if you want
you can flash the OS from ODIN
thanks for the responses.
I have upgraded to I9100XWLP7_I9100XEULP, and its working fine. the only problem seems to be its heating a bit where the camera is located . will read more topics and see why this is happening.

Yes though the newer dxlp9 was much better, previous one had bunch of issues including sleep of death.
Also that ROM introduces the contact/dialer lag bug. Which some how got to Google account and now every time I sync contacts it get back.
I deleted all my contacts and synced again and it's all better, tried on dxlp9 and was working fine, than I switched to my regular cm9.

For a start, if you remember your last ROM that doesn't had heat issues, flash that modem. Doesn't matter if you use GB modem on ics.
I flashed the modem of my region xxki4 which is 2.3.5 jpkj2 and had no issues of heat in ics.

P/S: I am a Malaysian and this phone was bought in Switzerland and I never root it before.

Basics.... Reflash any custom rom with Odin. That will help.

Actually my friend sent me this kernel>>>CF-Root-SGS2_XX_OXA_LP1-v5.2-CWM5.tar
He told me to flash the kernel then only install custom...so I can directly flash the rom to my s2
by using odin???

Yes, download and flash new rom, Then you have guarantee your phone will boot up because after flashing kernel you might get bootloop too.

This is because you flashed a wrong kernel for your phone.
# Quick question:
Is your phone on Gingerbread, Android 2.3.x or ICS (Ice Cream Sandwich), Android 4.0.x?
# If your phone is on ICS, then download and flash this kernel via Odin: www.gokhanmoral.com/public/files/siyahkernel/v3.0/Siyah-v3.5.2.tar
# If your phone is on Gingerbread, then download and flash this kernel via Odin: gokhanmoral.desean.net/siyahkernel/v2.6/Siyah-v2.6.14.tar

Thanks for that.
I have the I9100BVLPH stock ROM from T-Mobile UK on my phone so I downloaded the correct Chain Fire kernel (CF-Root-SGS2_XX_OXA_LPH-v5.2-CWM5.tar) from http://forum.xda-developers.com/showthread.php?t=1103399 and this caused the phone not to boot.
Thanks for the link to Siyah, I used the v4.1.5 kernel and it worked great.
Hello there.
I'm in a bit of a trouble so I need some help. I've bought an S2 for my wife from a guy (in Ireland).
The phone was locked on Vodafone so I tried to root it maybe I'll be lucky to unlock it with out paying nothing. So, the phone is on Gingerbread with a BUKJ3 kernel. I've downloaded last night a CF root but by mistake I took a KG3 instead of KJ3. After flashing with Odin 1.85 I got stuck on the boot screen with the yellow triangle.
This morning I've downloaded another kernel as in KJ3 flashed with Odin, the phone is starting but no network coverage, I tried with different Sim cards but nothing so I went in recovery mode and wipe/format data, system, dalvik and cache as factory reset as well. Since that moment the phone won't boot, it gets stuck on the boot screen and yellow triangle.
I can go in recovery mode and download mode with no problem but I can't make it start.
I reflashed the kernel, I don't know what to do and tomorrow is my wife's birthday and I was trying to surprise her with a nice phone but instead looks like she is gonna get a brick ( I hope not)
Thank you guys for any help.
Go to sammobile and get something like unbranded XWLP7 stock rom....flash via odin
Then use rachmats ics rooting guide
Backup efs folder and make nand backup
Then get unlock app(by helroz or chainfire)

Thank you for the reply. I don't mean any disrespect but for the last 3 hours I'm looking over kernels and forum and my brain is really wired now maybe.
I've had a look at sammobile but I can't find what you've recommended. A more specific link will be more than helpful.
Thank you very much anyway. If I'm getting advises it means I didn't bricked the phone so I might be able to fix it.
Once again thank you.
You just go to sammobile,then register,then firmware and files,then put the info in the 4 fields
eg
Smartphone
Android
Gt-i9100
Then uk/ire XEU (or vodafone or whatever..but unbranded better)
Then youll see a list about firmware version and their release date
Eg
Lpt 4.0.4 ics jul 2012
Lp7 4.0.3 ics apr 2012
So download lp7 4.0.3 and flash with odin.
Then use the rooting guide in my sig
Then do the other things I said.

Thank you very much. In the mean while I've managed to find exactly what you've said in your answer. I've choose the gingerbread version of the ROM cause that was what the phone had when I've bought it.
SO, now is it safe to go on ICS like I did half an hour ago with that Gingerbread rom?
Thank you and sorry about the noob question, never used an Samsung, only HTC.
Yeah just do what I said.......not what you think!.

Did it, thank you very much. The phone start but somehow I've lost my IMEI number and base band. I must be really unlucky.
I've read that Odia can help in this matter but if anybody has any idea, I'll be happy to make a donation for getting back the IMEI number.
Once again thank you very much.

It's always about read read more.... And don't flash anything unless you are 100% sure...

People contact Odia when theres a problem with their efs folder/no backup.
But you should have a backup and a nand backup.
I had the same problem yesterday and I restored efs folder/restored nand backup.....which got it back.
So try that or theres a thread about "restore imei in 9 easy steps".

I know I was stupid enough not to read before flashing, but now it too late to think about that.
the thing is I've never used a galaxy phone until these days and I wasn't aware of all this things and I don't know how to restore this NAND backup IF I have one, as I didn't make any backup before flushing. I hope I'll get some help from somebody and as I've said, a nice donation will be on the way to the helper.
Try GSII repair app.But you have to be rooted.
