Hey guys. I've been an Android & XDA user for a while now, so this question shouldn't be about a nooby-sitiuation.
My friend bought an AT&T Samsung Galaxy SII (SGH-i777) this week. I've been trying to flash CM7 ever since. I got the rooting done, the properly recovery (with no signature / "abort" problems)
The rom seems to keep bricking the phone. Its simply unflashable. I seen tons of people on XDA who got it to work, with barely any serious problems. I troubleshooted the problem myself, and its simply just the CM7 roms. I would do a full wipe, and then install the rom like I would on my other Android phones, and the installation is successful. When it boots, it gets stuck on the Galaxy SII boot screen (not the splash/boot animation screen) and it would stay on it with a yellow warning triangle on the bottom.
I tried flashing other roms, like Cognition X2, and they worked. Its just CM7 on this phone... which is odd because CM7 is usually stable (nightlies aside.) Especially since the 7.1 stable version was recently released. Anyone can help me get the rom up and going? Would be highly appreciated.
did you try to wipe dalvick cashe as well when you wiped data?
I just flashed it tonight myself and all I did was reboot into CWM and did a Wipe data/factory reset and then Wipe cache partition. After doing that, I simply flashed the cm7 zip file that was loaded on my internal sd. Rebooted and no problems.
I didn't have ANH ISSUES installing it but I know I read that some.people bad to flash it twice initially. So flash it, then when it goes back to the recovery screen flash it a second time. I also remember users on the international SGS2 bad to do the same thing. Most have no issues but I think they found that it depends on what you used to root your phone (on the SGS2 internationals) and I THINK some had to do the same here. Try it and if it works just hit the thanks button.

if you flash it and get stuck in a bootloop, just pull the battery, and 3-finger back into recovery to flash the rom again.
keep doing this until you get it up and running - took me a few times, including a couple of battery pulls.
How do you boot into recovery? I know On the SGH-i777 you have to hold the Vol down+back+power to get to the Download mode, but I tried everything to get to the recovery itself.

Yes. I've flashed many roms before, this seems to be the only one I had ever seen a problem with.

Word.
Edit: To boot into recovery vol up+vol down+power
Had the same problem. Read somewhere to install the ROM twice in a row in CWM without rebooting inbetween. Worked like a charm.
Thanks for the feedback guys. I'll try this in the morning once I get my hands on the phone again.
Saw this type of behaviour on occasion with cm7 on my aria. Sometimes caused by a bad download of the rom. Did you verify md5s ?

Don't forget to do a master data clear /reset before trying to boot the new CM7 rom for the first time - clear out the old stuff. Works perfectly here.

I'm having the same issue. I'm getting signature errors when trying to flashCM7.1 stable. I've downloaded it two times now with the same problem. My question is, I'm trying to flash from on the phone itself, storing the zip in the download dir on the phone as I don't have an sd card. Will this even work? I've tried looking around and all I can find is flashing from an sd card. I can get one, I just haven't yet.

That's the way I did it. Put the update in the same folder on the internal SD card. I can't even access my external SD card from CWM.

Hmm, I'm not sure what I'm doing wrong then. I did a factory reset, and wiped the cache and get the same thing. I know it wiped because now I have nothing setup on the phone when I boot normally. Suggestions?
Quit downloading the CM7 builds for the International Galaxy S II. They will NOT work. That is why it fails. Look for the Galaxys2ATT build.
Sent from my SGH-I777 using xda premium
I got the build by going to the cm7 website, looking by device, finding the galaxy s 2 and grabbing the stable one. So perhaps that is the incorrect one and I'll look closer for one that has att in it, whenever the site isn't going up and down. They seem to be having issues today.
Make sure you're installing the version located in this thread...

Double flash made it work. Thanks guys. + thanks for telling me how to boot into recovery lol. Great rom.
Sorry for the newb issues, it was the wrong version. I got the att version from the thread previously mentioned and that worked perfectly. Thanks!
hi everyone,
I am actually a long time custom ROM flasher started since Desire days, but registered recently because of this problem I have with the Tab 10.1 Wifi.
Despite me trying everything I can think of, I couldn't flash any other ROMs now, including GalaxyTask, Overcome, AOKP CM9, except the stock Honeycomb sans TouchWiz ROM, and of course PhantomTask. I am pretty sure PhantomTask is the last ROM I've flashed until this problem comes up.
I have made sure that I have done a full clean wipe every time before I flash any of them, wipe data -> cache -> dalvik cache, I even format /system partition, but still none of them works. They always get stuck at boot screen, unless the either one of the two ROMs I've mentioned, stock or PhantomTask.
I am sure that my downloads are complete too, as I've checked MD5 for each of them.
So I really don't know what to do now, any ideas?
I'd really want to test out AOKP
How much time are you giving it to boot up?
I've tried flashing CM9 yesterday, and I left it overnight to boot, it still didn't boot pass the logo, and the battery drained out.
I'll give it another try later
Which version of CWM are you using? If you aren't using one of these try updating:
ClockworkMod - 5.0.2.7
http://forum.xda-developers.com/showthread.php?t=1090289
Overcome Recovery v5.1.2.6
http://forum.xda-developers.com/showthread.php?t=1348533
ok I've tried everything I can, and still can't get this to work.
Then finally I've decided to try to unroot and restore everything to stock.
I've followed each and every step of this guide
http://forum.xda-developers.com/showthread.php?t=1474971
After everything is done, Odin is showing the pass sign, according to the video its suppose to reboot into Android, but weirdly its stuck at a black screen. So I unplugged it from the PC rebooted it by holding down power button. But now its stuck at the boot logo, and won't proceed, its been more than 10 mins.
I am still able to boot into download mode, but when I boot into recovery wanting to do a factory reset, it shows a black screen and nothing else.
any idea what's going on?
try using the overcome recovery posted above. there's a link in the post that will take you to the over come site. look for the restore yet tab section and use Odin to restore. follow their instructions exactly an make sure it's relevant to your device first.
this has helped MANY people who had some of the strangest problem start fresh. if you want or need specific links just ask I'll go to my PC where its easier to show you.

COOL! Thanks to you for posting that it worked. Knowing we help is one reason we keep trying to help.
For me personally it's the self gratification of just knowing.
It's kinda selfish I know but it makes me feel good and keeps me trying to help even in the littlest ways my limited knowledge allows.
Again thanks back at you.

Hi Guys
I flashed the leaked ICS but hate it. Can I flash to stock GB via Odin? What about the baseband versions etc.., would it matter?
Sorry, I read another thread but it's unclear and I want to avoid bricking. Thanks
As far as what I've read you can flash stock from Odin or even use CWM to a previous nandroid of gingerbread.
Sent from my SAMSUNG-SGH-I717 using XDA
If you got your Note from AT&T, simply flash this stock ODIN:
http://forum.xda-developers.com/showthread.php?t=1506330
I went from ICS back to Gb cause I missed the tethering and it was easy. Just make sure you clear the caches and all should be well.
Thanks.. I was worried of the different baseband would have any adverse effect, but it doesn't sound like it will. I'll give it a try.
I Odin'd back to stock and I'm in a world of ****. My phone cant do anything, it just gets stuck on every swipe and reboots about every 5 minutes. Does anyone have any ideas?
Mines fine..only baseband is different, phone works.
Before I Odin to stock, I booted into recovery, factory reset and wiped cache. Odin, then booted into recovery and performed another factory reset and wiped cache again.

You get it figured out? I did the same thing. . My old apps still there. I can tell it is gingerbread, but nothing works now. I hope you got your figured out!!
When I boot into recovery I get the screen that tells me to use the up and down keys and when I choose factory wipe, and press power button, nothing happebs. If I hold it down eventually the phone shuts off. When i restart it, nothing changed.

I had to revert from ICS to GB yesterday and, even tho I am on Telus, I had success by flashing the pda-odin-att-stock.rar image
I can't post links .. I'm too new. But literally.. google what's bolded above and you will find the hotfile link.
It replaced everything (including the recovery) ... FULL system image. Solved everything and brought me back to 100% stock.
So yes, I lost my root and my CWM recovery software.. but it got my phone working again.. I can reflash CWM and re-root as I need.
After the install, wipe cache, factory reset etc.
I too flashed the stock ATT rom but like the previous poster, it gave me a phone which started up but wouldn't work. When I tried to get into recovery mode, it went to a screen with the recovery mode stuff at the top, but with a yellow warning sign in the middle and some words about manual mode, and it would not let me do a wipe or reset.
Here is what I just did that did work.
I flashed the recovery-i717-cwm-b4.tar file with odin. This worked and allowed me to get into the "proper" recovery mode to do a wipe and factory reset, as well as a cache wipe. I then reflashed tieh the stock ATT rom, and my phone now is back to stock.
Ok, I'll try to be short about this.
I did the RegawMOD method and was able to install Liquid Smooth on the phone. (1.45)
When I was going to install an update for that things when odd. (I always back up, reset and wipe before hand)
The update didn't take however I was able to the home screen. As it was weird I went back to restore and the Trwp did not back up correctly. The file was bad.
I was able to get back to the home screen and then setup my phone. I decided to wait for a while until the roms grew up a bit.
Now I was going to install Mean 1.4 today so I downloaded as the post said and installed the radio. Downloaded the rom. When into recovery backup, reset and wiped. When I tried to flash the rom TWRP just started rebooting.
I have tried it several times and also tried to recover and TWRP keeps rebooting. Now I am stuck on the HTC screen.
What do I do now? I feel the recovery is bad.
Any help greatly appreciated.
Maybe a bad recovery flash or corupt download.. Try reflashing recovery through fastboot, download the ROM again, do a FULL wipe and reflash the ROM.

Thankfully I was able to install an earlier backup so at least I am running now. I have tried using Goo Manger to reinstall twrp 2.2. Just stays stuck at the download.
I haven't used the fastboot method before so I'll have to look that up. I want to get to mean 1.4 as included the OTA fixes because I have the wifi issue. Guess I'll have to wait until I have more time.
Thanks for the help.
Ok so I got goo manager to reflash the recovery.
Now I am on mean 1.4 and very happy. No more WiFi issues either!
Finally as useable as my OG EVO and dandy like this phone was ment to be.
Thanks for the help and thanks developers.
Very cool.

Well let me explain my predicament. The other day I flash somex's something explosive rom after a wipe of the everything I need to wipe ( Data,Cache,Davlik) When it was finished flashing I got to rebooting. I ended up with a blank, yet illuminated screen ( if that makes sense) I waited about 20 minutes. After coming to the conclusion that the ROM doesn't work I did another wupe of everything needed. Then i flashed JoseGalre's ROM since it has aroma it told me that it had an error and coundln't finsih the instalation. I wiped again and reflashed, same error. I wanted to see what would happen if it let it boot up w/o recovery and it ended up in a boot loop. I tried to go back to 4ext and it seemed to load up just fine but half way through the startup it ends up back in the bootloop. I ran Hasoon's all in one kit and flashed TWRP and it worked just fine until I flash a rom. It seemed to be working just fine then it suddenly crashes and we're back in the loop. I've been trying to fix for the last few days but to no avail. I marked the title as urgent because my parents are going out of town for the weekend and I really need a phone. They havn't a clue that it doesn't work becausse they get home before me. Any help would be appreciated a great deal.
I've had something similar happen and freaked out my phone was down for half a day.
Try booting into the boot loader by holding vol down and power boot into recovery, wipe everything then format everything except SD card and try restoring a backup. Hopefully you made one or two in the past.

I don't think you wiped properly. You needed to format ALL PARTITIONS. I can't stress that enough lol.
Edit: Go into bootloader first. Hold volume down then hold power as well. Choose recovery and format all partitions. If that works you're good! :thumbup:
Use the toolkit and flash 4ext. And make sure whenever you flash Roms that you format all partitions.
If that doesn't work you need to flash a RUU, get it back to stock, it will still retain S OF. Then flash 4ext again. Your problems should be fixed for sure if my first method doesn't work.

Hey guys it completly out of the question to format my internal storage so keep that in mind

You don't have to format internal storage just data, cache, system, and boot

If you want to use a ruu use the T-Mobile ICS RUU.

So i changed the name of the RUU i download to PH85img.zip and use the all in one tool kit to flash it. The black htc loading screen came up. I waited until it finished and then the bootloader came up with a list of things it head to unzip and then load. After all of that was finished it gave me an error. After reading a message that you should get an error ( i now realize this was at another stage) so i though nothing of it and rebooted. A black screen with 4 warning triangles came up. I let it load all day and when i got home i plugged it back in and I noticed it looked like it was unplugging after securing the charger in I came the conclusion that it wasn't holding a charge and dying on the battery. Normally I would leave it alone but when you plug in the charger it turns itself on. I've began living with the fact that my phone is bricked. But any help would be appreciated.
BTW is there a way to get data (music pictures contacts) that were saved on the internal storage?
Probably should have gone with full caps on the PH85IMG.zip
It's easier just to put the zip on your external sdcard and gone in to bootloader.
