Hello! Third day in the row I'm unsuccessfully trying to flash my SGS2 I9100 to Cyanogenmod 7.
Original firmware on my device:
Baseband version: I9100XXKI4
Build number: GINGERBREAD.XWKI8
Android version: 2.3.5
OS: Windows x64
Steps I have performed:
1) Flashed CF-Root kernel to get root and CWM (4.0.0.2) using Odin 1.85
2) Performed nandroid backup
3) Downloaded Cyanogenmod 7 Nightly build 116 and gapps and put them to internal sdcard's root directory
4) Rebooted in recovery mode
5) Performed data/factory reset, cache partition and dalvik cache wipe
6) Installed zip from sdcard.
It says installation complete. No error messages. Device reboots.
And here goes the most interesting part - device goes to Samsung Galaxy S2 screen with yellow triangle and keeps rebooting.
It doesn't stuck on this screen and it never reaches Cyanogenmod screen. Just boot loop.
Notes:
-Problem with getting CM7 itself, not with restoring after just another boot loop.
-Searched on forum and google before creating thread. Apologize if I was inattentive but none of I have found helped!
-No Kies is running while flashing.
Have tried this many times with little variations but result is the same.
Tried different nightly builds and stable version as well. tried to flash to XWKK5 stock firmware first (3 files) with no result.
Please advise!
Thanks.
Did you follow the CM installation instructions ? As far I'm aware you have to flash it twice in a row, no wipe. I have a feeling this is your problem.

It doesn't let me do it twice. I cannot get access to recovery mode after rebooting. Menu+Volume up+Power combination leads to the same Samsung logo screen and boot loop.
Download mode is available so can restore device to it's first state.

Performing the same steps as in instructions and tutorial videos.
Maybe I'm still doing something wrong during flashing?
Also have tried with RomManager but result is the same.
Will be very grateful if somebody helps to resolve this issue cause it's the 4th day i'm trying and flashing counter is about 50!
I'm having the same issue. And i also dont have a solution.
Screw that!
I've left any efforts to flash CM7 and flashed CM9 instead!

Hey all rooters,
I wanted to write this in the developer section of this ROM but the forum didn't let me since I had too few posts and was then regarded as a n00b. In a way I am but I have done a lot of searching and testing to get this ROM to run on my SGS2 but fails every time.
It gets stuck at the boot logo every time and here is what I have done after reading more then 55 pages of the official thread and also searched in it to find ppl with similar problem.
1. Installed XXKI3 stock via Odin. Rooted it with CF-Root-SGS2_XX_OXA_KI3-42-v4.2-CWM4. Booted into CWM Recovery. Flashed with Androidmeda_Hyperdroid-Amazing_Aquila-v1.0.0-signed.
Result: Stuck on boot
2. Since I saw ppl gone from LeoMar75 I restored a backup from that ROM and tried again to just flash from CWM Rec.
Result: Stuck on boot
3. One guy said he struggled with this for a week until he finally stock flashed XXKH3 to get the old boot loader.
http://forum.xda-developers.com/showthread.php?p=18328417&highlight=stuck+on+boot#post18328417
I did the same just before I went to bed last night. Stock installed XXKH3 and rooted with CF-Root-SGS2_XX_OXA_KH3-v4.1-CWM4. Flashed with Androidmeda_Hyperdroid-Amazing_Aquila-v1.0.0-signed.
Result: Stuck on boot
Of course prior to flashing any kernel or firmware I do a full wipe.
Is there anyone out there that can help me with information what exactly I have to do to flash this ROM? Like what's the preferred baseband, kernel and build number prior to flash?
I have tried to follow the guides in the official thread but of course with no luck. I have flashed a lot of other ROMs with no problems (Cognition 1.5.1, VillainROM, CM7, LeoMar75 etc).
Finally I just restored a backup to just get it running again and right now I have:
Android version: 2.3.5
Baseband version: I9100XXKH3
Kernel version: [email protected]
Build number: GINGERBREAD.XXKI3
I really want to try this rom so please.......HELP!!!
I tried some new stuff.
I read also ppl saying to "format /dalvik" from CWM recovery. I have no such option under Mounts and Storage (CWM 4.0.1.4). I have:
format /cache
format /system
format /data
format /sdcard
format /emmc
I formatted cache and system while I was on CF-Root KH3 but it still wont start up. I allowed it to recreate the Dalvik for 20-25 minutes.
I also read that you don't need to remove the yellow triangle if you only flash the Theme and not a Surgeon. But I thought I would give that a try.
But the guide does not say which firmware version should be used for this to work. I tried with the KH3 version but after flashing the stock firmware the CWM app was gone hence I could not flash the zImage kernel to permanently remove the yellow triangle.
I am completely out of ideas now and I really want to give this ROM a go.
Please.......HELP!!!!!
Close this thread. I'm in now with new version.
Hey Folks,
Yesterday i tried installing CM9 Nightly on my SGS2 (no root). I followed the "Full Update Guide at the CyanogenMod-Forum but ended up with the bootloop problem even though i precisly followed the steps here: http://wiki.cyanogenmod.com/wiki/Samsung_Galaxy_S_II:_Full_Update_Guide
Now my s2 wont boot and is showing the yellow triangle. I can get into Recovery Mode which shows "CWMR Touch v.5.5.0.4.".
i downloaded the latest nightly build but when i tried flashing CM9 as described i got an error message "verification failed".
any help is appreciated!
hi
try putting the phone in odin mode and install another rom
Factory reset first when you have bootloop.
no need to worry.
get the nightly again dont use the torrent. it should be 118 mb.
using cwm format system, data, preboot, cache.
now flash again. you should have the file on ur ext sdcard already.
If worst comes to worst then download a offical samsung firmware from http://forum.xda-developers.com/showthread.php?t=1075278 or from http://forum.xda-developers.com/showthread.php?t=1113928 if carrier branded phone then open odin and flash the files within download mode. If you don't know how to use odin then follow the guide within the first link
How come there will be a boot loop if everything is followed precisely?
You can try flashing the same again

Bro just remember that you must never flash a rom from within CWM or Rom Manager with our sgs2. I also did that and had same issue. Now, you can get into recovery mode and that is awesome. First things first, wipe everything, full system wipe, full wipe cache, full wipe sd card(format), next, attach your sgs2 to your pc and mount usb storage, transfer your chosen rom to sd card(I use Hydrogenics which is awesome). Next, unmount sd card, now flash hydrogenics. Now reboot system once hydrogen is finished flashing. You should never have issues like this again, especially with Hydrogenics. Also, do not forget to put gapps ics on sd card and flash it after you have flashed Hydrogenics. You can also use yellow triangle away app to remove the stupid leftover triangle from your previous rom flashing attempts, if you got LPB. Anyways bro, have fun and do not stress too much because the sgs2 is really hard to brick. Also, remember to check the md5 sum when downloading a rom, this lets you know it has not been tampered with and the entire rom is there.
Hello everyone,
I recently bought the international version GT-I9300 simlock free running android 4.1.2 build JZ054K I9300 00XXELL4 . I researched how to root my device and I successfully did so using the Samsung GS3 Toolkit v7.0 selecting the 4.1.2 build JZ054k I9300 ELLA. I then proceeded to download ROM Manager to use the application to download the stable 9.1.0 Cyanogenmod from my internal memory where I had saved the document. This is when things started going bad. I did not wipe data/factory reset the device before I started uploading the costumROM. I am now in a boot loop where I constantly see the facy boot animation of CM 9.1.0. no matter what I do. I have entered system recovery only to find that I have access only to the standard android system recovery <3e>. I tried to wipe data/factory reset and to restore my device using a stock samsung file that I reflashed using Odin 3.0.7, to no avail. Many different reflash attempt later, including the original 9.1.0. cyanogenmod file and a nightly build version 10.1, I ran out of inspiration. I would be very grateful for any suggestion to what to do. Still have access to download and recovery mode however not with ClockworkMod-Recovery.
TL;DR:
I soft bricked my I9300 as I am in a boot loop with CM 9.1.0 . Only have access to download mode and system recovery <3e>. What do?
Thanks in advance
Download stock i9300XXELLA from here http://www.sammobile.com/firmware/?page=3&model=GT-I9300&pcode=BTU&os=1&type=1#firmware you will need to register to download the file
Boot into recovery and do a factory reset then boot into download mode and install via Odin,
The root using this http://forum.xda-developers.com/showthread.php?t=1957273 zip is in post 3
The use this for recovery http://forum.xda-developers.com/showthread.php?t=1943592 instead of CWM
Thanks a lot for such a quick reply. I'm going to try it out immediately.
Hey guys!
Since I tried building Firefox OS -Boot2Gecko- on my Samsung Galaxy S2 (i9100) (FYI: I followed this walkthrough) , I'm having quite a hard time making my phone boot on any ROM I try to install. I still have an access to CWM Recovery and to the Download mode
* After failing to flash B2G's Gaia on my phone, I tried to flash the kernel back to the original one and to restore the CM 10.1 NIGHTLY backup I made before doing all this mess. No changes: stuck at CM's boot screen.
* Tried to get back to a stock firmware and ROM, stucks at boot screen ("Samsung Galaxy S II GT-I9100" screen), even after a wipe data/factory reset, wipe cache and wipe dalvik cache.
(In fact, I achieved to boot on a stock ROM once, but after some other manipulations to get my CM 10.1 back, I now can't get it to boot on any of them anymore.)
* I tried to follow the rooting + CyanogenMod walkthrough on CM's wiki, but the same happens: stucks on boot screen. However, after a wipe data, I reach CM's boot animation, which runs indefinitely.
* Right now I tried flashing with Siyah's Kernel, since the flash counter is not any of my concerns anymore. Whatever I try, I can't get anything to get past the "Booting the primary ROM" message.
However, I installed a stable CM9 on the secondary ROM and... it actually works. But even when cloning 2nd ROM to the 1st ROM, can't get the first to boot anyway.
I am not an expert in Android OS architecture, but could it be related to some kind of modifications made by B2G's build & flashing? Maybe some files in the /data or /system partitions have been altered and are not replaced when fllashing, leading to ROMs not loading up?
Any advice on this is welcome.
PS: English is not my main language, sorry if things aren't explained clearly. Tell me if you need any clarifications about it!
hey there,
i have a similiar problem.
i got the info to reflash it using ODIN.
one user told me, that maybe the NAND-RW could be corrupted....
so iam trying it right now...
good luck
Wipe kernel/rom data with a cleaning script. You can find them in dev sections.
Well I flashed it many times with Odin (or Heimdall when I was on Linux) and I saw no improvement.
I don't think my NAND-RW is corrupted, as I can still boot on Download or Recovery mode.
Just found this tutorial, is it worth the try?

This one http://forum.xda-developers.com/showthread.php?t=1363738 (Kernel) and this one http://forum.xda-developers.com/showthread.php?t=2100558&highlight=script (ROM) ?
Ok so I tried the cleaning scripts I linked on my previous message, no changes. I can still boot on Siyah's second ROM, but can't get past the "Booting primary ROM" message.
Ideas anyone?
Hi folks, mid last week I woke up to a non responsive Galaxy S2. It's been happily running stock Vodafone ICS for over a year, and somehow spontaneously went soft brick on me. Gets stuck at logo screen or goes into boot loop.
Download mode is accessible. I can flash through Odin (1.85 and 3.09) and it reports success. I have successfully put CWM (various versions) on it can can boot into them fine.
Recovery mode is also accessible and appears to be working fine. I can access external SD card no problem.
Attempting to flash through zip from external SD aborts with Mode 7, reporting bad zip or unable to read source file. I have tried removing asserts from install script (educated myself to the risks and made sure the ROM was correct!!) and multiple versions of CM (10.1.3 stable, 10.2 nightly) and multiple versions of CWM recovery (6.0.2.9 is what I've been using mostly, as recommended by CM guide)
Tried running GS2ROMNukeV2.12.zip which reported successful wipe, then attempted zip install from SD with same result (aborted mode 7). Repeated wipe and attempted stock (I9100TDVLSK_I9100THUTLSD_I9100TDVLS3_HOME.tar) from flash through Odin. Reported success, phone booted into recover and applied KOR CSC successfully, then reboot and still stuck at logo screen/boot loop.
I have attempted the fix in http://forum.xda-developers.com/showthread.php?t=1449771 as best I could wish the resources I could find, but it's hard to follow to the letter with the links broken!!!
I have not tried repartition with PIT as I'm not sure where to get an appropriate PIT file. Advice on this appreciated!
I want to make this clear because people seem to not want to believe it: I did not soft brick my phone flashing it. My best theory at this point is some kind of memory corruption or hardware failure that's causing a boot loop. Any help or suggestions would be appreciated. This week I will probably take it in to a repair shop and hope for the best, but tomorrow is a public holiday and I've got nothing to lose by trying any more suggestions.

If memory serves me right this is due to an old version of Recovery, i had the same thing, updated recovery and it flashed zip fine. just as you know. :fingers-crossed:
