[Q] Can I fix Galaxy SII after a failed rooting? - Galaxy S II Q&A, Help & Troubleshooting

Hi,
I updated my Galaxy SII to ICS (BVLPB) via Kies and I lost the previews root, now I tried to root it again with method from Chainfire but with no luck and my phone don't start anymore. I tried to put back the stock kernel from intratech but still with no luck.
I can still go to download mode or recovery mode, but this is the only thing I can do.
Now the question is: What can I do to fix my phone, can I fix it?
Thank you very much.

yes you can
go into download mode use fusdownloader to get a ICS stock rom for your galaxy
open odin 1.85 plug in phone select pda and add the downloaded rom (from fus) and then apply the update
this should fix your phone and restore it to ics

...
Did you try: Wipe data/factory reset and wipe cache ?

Try a wipe data/factory reset, if it still doesn't fix it, grab an official ICS version here and flash it with Odin.
Btw, be sure to read the instructions for flashing on that thread.

Thank you all... I manage to make him start again... I didn't try flashing the stock rom because I was afraid that I'll lose all my data.
Thank you all again.

No ROM Booting

So i managed to solve the problem that i had.
When i said that i could flash only the stock one, i was flashing XXKI3 as one file after each failed attempt to flash a custom one.
So i tried and flashed another stock rom, again as 1 file. after the flash was done the phone again stucked at first screen wit the triangle.
After that i thought that something was really messed up in the phone and flashed again XXKI3 with PIT and multiple files and offcourse RE-Partition.
After that flash a stock rom with 1 file and modified bootloader from Intratech's thread, this way you can also reset the binary caunter with a jig (can find many on ebay).
After finish flashing and first boot
root with CF kernel and flash any custom rom. It worked as it should. Now i am on a custom rom and trying to see which one suits me best.
Thank Jiganet for some may be needed modified bootloader which is recommended so you can reset binary counter.
Everyone tha nk you for your suggestions and help.
any rom that i install is not getting beyond the bootlogo. i had xxki3 stock with cf-root xxki3 kernel.
every install i make full wipe on everything before(data, cache, dalvik).
any body any idea?
only stock rom working.
The first boot takes some time. Are you waiting that long?

1. Enter Clockworkmod recovery
1a. Do a Backup (not a must, but i suggest) from the cwm recovery of your current rom/settings.
2. Wipe Data/Cache Factory reset
3. Flash the new rom you want
4. Again (not needed but well..) Wipe Data/Cache Factory Reset
5. Wipe Cache
6. Advanced -> Wipe Dalvik Cache (this is why you get bootloops)
7. Reboot to system
Wait 4-5 minutes and you will have your new, shiny working rom.
Hope it helps, cheers
yes. more than 10 minutes.

Mh strange, the strange is.. with the stock rom is working.
Looks like your phone dosnt like the rom you are flashing so the quesion now is:
Are you sure, you are flashing a rom your phone can read? I know the i9100G and the AT&T versions cant be flashed with the standard (i9100) S2 roms (there is a specific thread i think here on xda for those versions)
mine is an unbranded i9100 from Greece. i am flashing the correct roms.

every body read first post managed to solve this.
Hi was there a solution to this problem as I seem to get it with EVERY rom I try to install from zip?
Hi to all, this is my first Post and this is my First Android I come from an iPhone 2G, iPhone 3g, iPhone 3GS and my last phone was an iPhone 4!!! now I'm extremely happy with my new SGS2!!!
I have been searching a lot!!! for a solution for this flash loop issue,
1 - I have flash to a stock 2.3.5 KI3 samfirmware,
2- then I have Odin>PDA>cf-root-KI3-4.2.tar to root my phone.
3 - After that I downloaded 3 custom roms, DarkyROM2_KI3, VillainROM-3.0.0-signed and Cyanogen cm_galaxys2_full-112. put them on my root internal sdcard.
4 - booted to ClockworkMod Recovery menu.
5 - Wipe Data/Factory Reset
6 - Wipe Partition Cache.
7 - Install Zip from sdcard.
and every thing seems ok, but when i restart, it stays on the boot loop, even if i manage to enter to CWM Recovery menu it says that E: Can't Mount ... bla bla bla
I had been trying to put a custom rom so much that my binary counter is now on 10
I'm going to try what you wrote on the first post!
Restore to stock KI3 firmware using pit file and repartition.
after that install the cf-root kernel. Restart and try to install any custom firmware.
Hope it works
Not it did not work, Maybe the problem was Wipe Partition cache after installing new rom, going to stock and repeating
I'm having this exact same problem, please post here if you find an answer to your problem.
I first installed checkrom with no problems, then i decided to wipe and try install dlevrom but after rebooting i'm left with the same problem as above.
It's only when i flash stock 2.3.5 KI3 through odin with pit, repartition, all checked that my phone works.
I then repeat the steps of flashing cf root through odin and then try flash a custom rom, either checkrom or dlevrom and neither work.
Another try another fail!
I have no idea on what else can I do!!! tried again and nothing! I tied cf-root 4.1 and nothing and cf-root 4.2 and nothing!.
I'm having this exact same problem, please post here if you find an answer to your problem.

After i got the stuck on boot! I can restore to stock by only using the PDA, I don't need to set the pit file again!, but I'm usign all the files on Odin to see If that makes any difference but nothing!!!
I wonder how mariosraptor did it!!!! Can you throw us a light???
I have explained it on first post. Just follow step by step the first post directions.
Sent from my GT-I9100 using xda premium
Nope it didn't work
The steps I did:
1. Restore to stock using PIT, PDA, PHONE, CSC.
2. After it boots root the phone with cf root 4.1 for ki3
3. Use CWM Recovery to flash the new rom on internal sdcard.
I have been doing it with wipe data, wipe cache, wipe develk.
Nothing is there a step that im missing?
Thanks
SOLVED!!!!!! JAJAJA
The only problem, was one minor thing, a little thing called Bootloader!
I installed the old bootloader!
find it here: http://forum.xda-developers.com/showthread.php?t=1075278
And after that every thing worked perfectly, no boot loops!!!!
Hope it helps!!!

[Q] Recovery Mode before Odin?

I am pretty new at this. I have flashed the phone a couple of times after I updated to ICS through Kies (bad move)! Am currently using Gingerbread 2.3.6 but I now want to go back to a clean all new original stock firmware as my phone keeps randomly going into Kernel Panic Mode.
So, my Q is; Can I first go into recovery mode and wipe data/factory reset, wipe cache partition, reboot phone and THEN flash with Odin? Meaning will the phone be capable of being flashed with Odin after all the wiping or will I need to save the firmware zip file on SD card and flash boot from there? I have the original stock firmware and I would like to have my phone as it was! I am NOT ROOTED nor do I want to be!
I just want my phone as it was! No more buggy bugs!
Please help! Have scoured the net, no answers to this particular question!

To have stock do this:
this is en example that help u flash with odin. (Proceed at your own risk)
Step by Step Instructions:
Download the Android Firmware
Extract the downloaded file ‘I9100XXKL1_I9100OXAKL1.rar’ to get these 3 files:
CODE_I9100XXKL1_CL783870_REV02_eng_mid_ship.tar.md5
GT-I9100-CSC-MULTI-OXAKL1.tar.md5
MODEM_I9100XXKL1_REV_02_CL1085162.tar.md5
Download Odin software
Disconnect your phone if it’s connected to PC. Switch Off your phone. Wait for vibration to confirm complete switch off.
Now, put the Galaxy S2 in Download Mode — press and hold these keys together: Volume_DOWN+Home+Power.
this is required to install the XXKG1 using Odin PC Software.
Open Odin (from step 3) — Odin3 v1.85.exe.
Connect your phone to PC now. You should get the message “Added! !”
under the Odin’s message box in the bottom left. If you don’t get this message,
than probably there is a problem with drivers. Make sure you’ve drivers installed.
Important! On Odin, Do NOT tick the ‘Re-Partition’ checkbox, but keep the ‘Auto Reboot’ & ‘F.
Reset Time’ checkboxes ticked. Do not touch any other checkbox or tab or anything, except as required in step 9 below.
Select these files in Odin at respective tabs (check out the screenshot given at the top for help):
Click the PDA Tab, and select CODE_I9100XXKL1_CL783870_REV02_eng_mid_ship.tar.md5 (from step 2.1)
Click the Phone Tab, and select MODEM_I9100XXKL1_REV_02_CL1085162.tar.md5 (from step 2.3)
Click the CSC Tab, and select GT-I9100-CSC-MULTI-OXAKL1.tar.md5 (from step 2.2)
Now, hit the START button to let the process begin.
When process at Odin finishes your phone will automatically reboot —
and you can unplug the cable then.
Plus, you’ll get a PASS (with green background) message in the left-most box at the very top of the Odin.
If it’s red and with FAIL written over it, the process flashing process wasn’t successful.

I ALREADY know that thanks very much, it would be nice to have a proper answer to the proper question I PROPERLY asked.
Yes.
You can factory reset via stock recovery no problems.
When you flash stock Samsung firmware via odin you will end up with a completely new and clean system as long as the factory reset has been done prior to flashing or if the firmware is a wipe version.
What you will still have is all the leftover directories and files on your internal sd card. You can simply delete all of these and factory reset.
There you go. Clean New stock firmware.

So just so I'm clear......
I can:
1. Go into recovery Mode on phone.
2. Wipe Data/Factory Reset
3. Wipe cache partition
4. Reboot phone
5. Flash stock firmware via Odin
......and then all is well?

Root (CF-Kernel) --> Stock Firmware --> S2 just booting, no reacrtion

Hello,
I installed the CF-Kernel to my S2. After that, I installed the resurrection remix rom.
Now I wanted to install the stock firmware again, so I downloaded the stock rom, where I thought, that this is the one that my S2 had after starting it the first time.
I installed this official firmware: http://androidfirmwares.net/PhoneFirmware/Download/35
DBT seems to be the right for my german S2, and it had the number "XWLP7"
It's also a Galaxy S2 i9100. Not the G version.
Could someone please help me out? My S2 is just booting, it won't start. It's just showing the official boot screen for over 30 minutes now. Even a reinstall via odin didn't work.
Thanks a lot in advance!
when changing from a custom rom to a stock rom, it is essential to perform a wipe / factory reset. shut down the phone (if you are still booting ) and boot into recovery and do the wipes from there, format data, cache, dalvik cache and fix permissions.

1. I'll advise you to flash latest 4.0.3 UHLPS/XWLPG etc. If you don't know why read here: forum.xda-developers.com/showthread.php?t=1756242
2. To flash, follow these steps:
- boot to CWM recovery
- wipe data/factory reset
- reboot your phone to download mode
- flash firmware via Odin (if you don't know how to flash via Odin, please read tutorials. There are many online)
Done

if you have custom rom or stock rom coocked the kies cant help you.
do these solutions in order :
>>>solution 1 : in recovery do facotry reset and install rom , wip cache and dalvick. the first boot take time. so wait. if not worck try to format system before flashing rom.
>>>solution 2 : factory reset in recovery then install stock firemware by odin after flash is complete enter to recovery and do factory reset again. the first boot take time. so wait.
>>>solution 3 (danger, do it only if you give up if you dont have any other solution) : flash stock firmeware with odin but cheek nand erase all in odin, after flash is complete enter to recovery and do factory reset(compulsory).the first boot take time. so wait.
use latest odin version.
good luck.
