T-mobile Samsung Galaxy S2 / CM9 Stuck at boot screen

So this is my first time posting so im a pretty big noob at this, but here it goes. I have a T-mobile Galaxy s2 that i rooted a few months ago. Today CM9 released the stable version, which is what Ive been waiting for so i decided to try it out. (again, Ive never flashed a rom before I only used the stock one) I followed all the steps to do it and now its been at the boot screen for over an hour. The instructions said be patient, but I feel that over an hour is too long. I decided to pull the battery, hoping I could go into recovery mode and do a factory reset. When I try to go into recovery mode it vibrates a couple times but doesn't go into recovery mode. I can't go into download mode either. Does anyone have any idea for what I can do to at least do a factory reset? Thank you in advance for the help.
Edit* After going into recovery, I tried a factory reset but its still trying to boot into CM9. Why is it doing that?

When factory reset it doesn't go back to stock rom .
How are you flashing the rom?

Actually, for some reason recovery was being really strange. I had to hold down the power and the volume buttons 3 times for it to go to recovery, then I restored an older backup that was on my memory card and it took a while then finally worked
Do you by chance know why it didn't work?

I've been getting this same problem. I can get back to recovery and recover from my backup just fine, but every time I try to get CM9 working, it won't go past the boot screen, even after about an hour of waiting.
I've tried the CM9 hercules stable release off the CyanogenMod website and the CM9 RC2 download through ROM Manager, I've tried installing through ROM Manager and straight from booting into recovery, and I've tried putting the zip on both external and internal storage just in case that might conceivably affect something. I have the same problem every time. I'm using CWM 5.0.2.7 and currently on rooted stock.
Any ideas on how I might get this rom working?

You need Darkside super and cache wipes, which are both available in a sticky with an obvious title in the development section of the forum.

What he said. Non touch clockwork mod for this phone has a broken cache wipe function. Will cause infinite boot. Flash tdjs cache wipe NOT THE SUPER WIPE. and you should be golden.

Phone keeps rebooting

First off, I am aware there are other threads regarding this issue but there appears to be an issue with my phone that is not mentioned in other similar threads so I am starting a new one.
I just updated one of my apps and then all of a sudden my phone keeps rebooting. Having read other threads, I figured I will go in and uninstall the app and see if that fixes it. However, whenever I even try to open something like task manager or applications in settings, it freezes and then reboots again before I even get the chance to uninstall. I was able to use titanium backup to uninstall the app but still no luck, it still reboots.
So I go into cwm recovery mode and I am just going to wipe data/factory reset, wipe cache, etc. since I have a backup of the rom ready. But the phone freezes and then reboots right when it begins the factory reset process.
So now what is there left to do but to download the stock ICS rom or a custom rom, whichever, and use odin to install the md5 file.
Is there anything else I should try before I attempt to just flash to stock (or custom) rom using odin?
Thanks for your help!

Try this;
Download and flash tdj's darkside super wipe
Flash Jedi Mind Trick v3 ROM
Flash tdj's darkside cache wipe
Reboot and Wait for like 10 mins for the ROM to settle and then reboot.
And don't restore app with data in titanium. First try restoring apps only. Later on restore data for important apps.

I decided just to odin back to stock. Better to work with a fresh OS again instead of restoring what was still probably a buggy rom.
But thanks for your input.

Alright. You're welcome. Good luck.

Help, T989 phone stuck on Cyanogen 9 blue screen...

I rooted my phone fine. I unlocked my phone fine.
I installed clockworkmod recovery fine. I flashed clockworkmod. I backed up my rom at the stage after rooting and unlocking.
I then downloaded cyanogenmod from the app's download page. I downloaded it and installed it. I used the default selections which is "wipe delvich cache"
When I turned on my phone, it stays at the blue screen with the alien forever.
Any help on what to do? Thanks!

Reflash the ROM using these instructions. You probably wiped the wrong way.

I had same problem installing cm10 with cwm. In order to get past boot animation you have to use the dark side cache wipe after flashing ROM. Ideally you should -darksidesuperwipe then flash ROM then darksidecachewipe. I like to let it boot without gapps first. Set up WiFi and all that.
Try rebooting and flash darksidecachewipe. Then reboot. I always had lingering problems until I flashed twrp. After twrp is installed there is no need for darkside scripts.
Worth it to just get twrp and redo.

Wow very informative and helpful too bad the OP could not at least give you some props and let you know he saw this and you helped him out. People panic come on here and ask questions then never come back to thank or at least acknowledge the help... Hey for that I will give you your first xda Thanks.... :good:

Try returning to stock and try again. Do things in this order: 1. Root, CWM, ETC. 2. CM7 or another 2.3 ROM (usual wipe) 3. CM9 (again, wipe)

[Q] Differences between clockworkmod recovery amd CWM-Based recovery?

Hi all, ive had my Tmobile samsung galaxy s2 for awhile now, and i finally decided to root it (and did it successfully) a few days ago (yay)
Ive done a bit of research for what I can do while rooted, basically after CPU setting, save battery life when idle... Simple things
But ive been meaning to try flashing a ROM. But I want to make sure i know absolutely everything needed to know to flash one. I had a samsung tmobile sidekick that I was able to root and flash Gingerclone on, but I remember it had alot of little details while installing that simply missing one could seriously screw up your phone
So first off, if anyone has had the sidekick: Is flashing/ installing roms as complex on the sgh-t989 as it is on sidekick 4g?
And secondly... After rooting my galaxy, i no longer have the stock android recovery (obviously)...... Instead it is replaced with CWM-based recovery (i think 5.0.2.2?). Is there a difference between this and Clockworkmod recovert (which should show an orange screen)?
I wanted to use ROM manager but opted not to when it told me that I "needed clockworkmod recovery installed" to work.
A little help, please?
Thanks!

Okay, great! Glad it was so simple lol.
Now about my other question... Let me explain. When I would install a custom ROM on my sidekick, i remember having to do all sorts of things like unmount system/ unmount SD card before installing and remount them after (i dont remember the exact methods... Dont quote me on that).
I know the general procedure of basically Wiping data, Wiping cache, Wiping delvik cache... But does the galaxy s2 require checking of all of that unmounting/mounting?

Flashed many roms, and no need for all that. Just make sure you wait the 10 minutes after flashing a rom.

FlaShing roms on this phone is so simple "that even a caveman can do it". I would also advise to ditch clockwork recovery and install twrp, also never use rom manager to flash roms. Just follow the op's instructions on what steps to follow to flash the rom successfully. Also no need to mount and unmount anything. Good luck.

Awesome! Thank you all for your replies, glad to here that flashing is much simpler on this phone
I really wouldnt recommend anyone rooting a sidekick as a beginner. It was my phone, i soft bricked ot my first time. Ugh, it was such a hassle! And it left me a little traumatized to try anything on this. lol!
Thanks for all the help!

Here are the genreric steps to follow to flash a rom (and yes, TWRP is recommended instead of CWM):
- place the rom zip on the internal storage
- place a copy of the radio zip that you have on the internat storage (for safety reasons)
- copy Google Apps zip if it is not included in the rom (most roms do not have these included, but the dev might provide a tuned version)
- reboot phone and enter the recovery menu (hold vol up + vol down pressed while booting)
# In recovery mode
- wipe data
- wipe system
-(Use Darkside Super wipe if still on cwm 5.0.2.7 or below)
- flash rom
- flash gapps (if missing from the rom)
- wipe cache/ dalvik cache.
- reboot and wait 10 mins
- reboot and wait 1 minute
- enjoy

If you are planning on flashing a Rom on your phone of course twrp recommended and you should definitely try Jedi mind trick x2 for the t989 Hercules. It is the most stable Rom on the Samsung galaxy s2 T989 T-Mobile. The instructions above are the best instructions you should follow. And read it carefully or you will brick your device. If using twrp follow the twrp method. And if using cwm make sure you use the extra cwm steps. It is super important you follow them unless you want a fancy paper weight.

I just flashed my phone last night to the Liquid smooth rc 9. This was my first root and flash. I used titanium backup for the apps, used ROM manager to flash to the latest cwm. Here is a link I used

[q] afraid to do anything now!

I was on Stock T999UVALH2
Rooted and all was fine
A few months later I did the small update to T999UVALH4
Again all was good.
Did the Update to the 4.1.1 OTA and phone went into a boot loop! (for a long time and while I was trying to do
different things to try to recover the phone.) I tried a whole bunch of stuff, and after trying to get into download mode,
and missing it, the phone booted into a screen that was saying it was updating file x of 25x files and counted till the last update file, and rebooted to a screen asking me to choose which launcher to use.
I chose what I was then using, and all the stuff came up, and the NEW rom was running! T999UVDLJA
Build # JRO03L.T999UVDLJA
I began having weird issues, and it was recommended I clean the Dalvic Cache.
Well, I cleared the cache with CWM and the darn thing started counting, and upgrading all over again! WTF?
I don't know what/why it did, but it rebooted and all was like before the cleaning. I have a few more stuff that just do not seem right, but I am afraid to "monkey around" with anything till someone can tell me what was happening (re flashing the rom by itself?) and what I should do to stop this behavior, or if that is a normal thing. I once cleared the cache, on another android HTC, and it just cleared the cache and rebooted.
Maybe some of our "Gurus" can tell me what I should do, if anything.
Thanks to all for any advice that might be forthcoming!
Aloha!

What recovery are you using?
Sent from my SGH-T999 using xda premium

My Recovery
CWM - based Recovery v5.5.0.4

So, you did the jellybean update without the stock recovery, yes? That's the trouble.

I'd flash a rooted jellybean Rom; since you have clockwork.
But you could go back to stock and then update

I was on a stock rom, and folowed all the "updates" as was said that it was necessary for jelleybean...

Just so I don't grab the wrong thing again,
Would you , per chance, have a link to a rooted JB Rom?
Thanks!

Here is the link to the stock JB rooted rom, it's also safe from triggering the counter if you are worried about that stuff.
http://forum.xda-developers.com/showthread.php?t=1771687
Just flash it from Odin and you will even keep all your apps and such too.

odin flash with the jelly bean .tar image, bone stock.
then root with chains cf auto root (OG dev section)
then download the new clockwork mod touch 6.0.1.2 ..... put it on the root (meaning in no sub-directory, or in no other folders) of your internal sd card, and rename it to cwm6....
download an app called terminal emulator, open it, type "su" without quotes, then grant the app root access, then run these commands, hitting enter after each one:
dd if=/sdcard/cwm6.img of=/dev/block/platform/msm_sdcc.1/by-name/recovery (hit enter...and you will see an output, xxx data transferred in xxx seconds blah blah)
reboot recovery (hit enter again. oops. phone rebooted....... into your new recovery)
good luck

wait, isn't it normal for the "android is upgrading/optimizing x of y apps" to appear after clearing cache? That usually happens when I clean my cache.
As for the other problems with this rom, i guess you should Odin using the method that doesn't trip your flash counter, as stated above
Sent from my SGH-T999 using xda app-developers app

That's normal. It will happen every time it has to rebuild dalvik cache.
Sounds to me like you need to backup, wipe data and start fresh and clean.
Sent from my SGH-T999 using xda premium

I have the same thing happening to me each time I clear cache (optimizing x apps of y), that's completely normal. As to other problems that you said are happening just flash root66, rooted stock 4.1.1 rom, using odin and everything should be good.
Good luck
