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!
I've already asked in the relevant ROM thread but thought I'd try here in case anyone else has had a similar issue.
I'm currently running Westcrip ICS 9.4 and tried to update to latest version but phone freezes a few seconds after booting (have to restart/battery pull)
I've tried wiping data/cache/dalvik/fix permissions but get exactly the same problem.
I've tried flashing stock GB through odin which works ok and then flashing again but get exactly the same problem.
I've tried flashing bezkes aokp but get exactly the same problem.
Thankfully my 9.4 backup restores OK and runs without any freezes.
The only thing I think it might be is something dodgy/corrupt on my internal memory or SD card. Is it safe to wipe these? I dont want to move my backup as I've had MD5 problems when trying to restore in the past.
Does anyone have any other ideas? I've looked around on the forum/google but can't find anyone else reporting the same problem.
This is driving me mad!! Am I missing something?
No ideas?
Ill try again after clearing internal storage. Can someone recommend the best way to do this please?
I should have said that i get the freeze problems with no non rom apps installed...

Well you are using buggy beta ICS base .
As you can flash and use a stock rom then the problem is the rom you are flashing .
Possible corrupt download .
jje
Thanks for the reply. I tried downloading again but still have the same problem with resurrection and bezke so will try loading a stock ics base through odin when i get home tonight. Do you think my 9.4 resurrection base could be the problem? I read that on earlier ics roms that you should flash stock ics first?

No idea really but how can you flash a stock ICS its not released .

I've been using Bezke's AOKP for 5 days now, without any problem, so the problem is definitely not in his ROM.
When you flash it, try the following:
after wiping data, cache and dalvik, go to mounts and storage and hit format system. It could do the trick maybe...

Arghh!!! Tried this and thought it had solved the problem. I've managed to install the new paradoxx rom now and even reinstall my apps and set up email account, but phone eventually freezes again. I've even started getting random freezes in CWM now! What I cant understand is why my phone is still rock solid running my westcrip 9.4 backup??
I think I might have flashed my phone to an early grave!!
That is really strange. Sorry that formatting system didn't help
I can get into recovery and download mode, flash stock Rom with Odin and Heimdall to completion but phone never boots up completely. Nothing but boot loops.Goes between Vibrant screen and Galaxy S screen.I'm at my wits ends. I hope some one can suggest something.
What did you come from? CM7 / CM9 ICS?
Did you repartition with Odin?
More info please.
Originally phone had ICS 4.0.4 CM9 ICS and I tried to go back to stock.Big mistake.

I have flashed with Odin to stock 2.1 coming from an ICS rom a few times and never had a problem, so i don't think that's the issue. Maybe try flashing a stock kernel in recovery mode or you can use Odin for that too I believe. I'm still learning this stuff myself but it sounds like it's a kernel or bootloader issue to me. Just to be sure, are you absolutely certain you flashed a Tmobile vibrant package and not something meant for another company/phone? Sorry had to ask

Also coming from ICS to stock you MUST repartition the phone.
Managed to install a T959UVKA7 rom but now I can't mount sd card. It's greyed out and states to insert an SD card for mounting. I can erase sd card but it states sd card has been removed. And when I go Additional storage/mmt/emmc and mount sd card I get damaged sd card.I have 0.00B internal storage and mnt/emmc space is 1.86gb which is my external sd card. Almost looks like internal and external storage are reversed. What's up
I always recommend Odining to stock from CM7 as CM9's DM is, at least for me... non-existent. As for your SD card issue, you may want to Odin to stock again.
I agree. You should try to get to JFD and hit repartition. If you need it, the AIO Toolbox is in my signature to download. It has all JFD pit/tar files, Odin and will get you cleanly back to 2.1. Read toolbox's OP in the dev section for directions.
Did everything you suggested but I just end up in a boot loop. I have tried going back to stock many many times but never get out of the boot loop.That's why I installed CM7 from the external Sd card as it was the only way to get anything on the phone.

Wait you got a boot loop after using ODIN to restore?
Yep Please read original post above. No matter what I do I just get the boot loop thing. How do you just install a kernel through Odin? Haven't done that yet.Not sure how to do it or what kernel to use.

Easiest way to do it in my opinion is through recovery mode. Download a kernel that is compatible with your ROM, go delete cache partition and dalvik cache from the advanced menu then install from sd card just like you would a ROM. The kernel MUST be compatible with whatever ROM you are running. Check out the kernel bible thread for a list of kernels and what ROMS they work with. I personally never used Odin to flash a kernel but I believe the kernel bible tells you how

ok i have searched and searched before i post so if i missed it im sorry, So i was playing a game and my phone went off with a dead battery, plugged the charger in and waited 5min then booted back up and the it went into a loop thing is i kinda know my way around the phone i have rooted the installed many roms and kernels on the s/s1/s2/s3 and htc but this loop has me here as a last resort, heres the deal.....
i was using the latest syiah kernel and super nexus, it ran almost perfect anyway once the loop started i reinstalled siyah ... no joy then i did same with the nexus rom both installed perfectly through cwm, but didnt solve the problem so i tried cyanogen10.... same loop after logo then i got the latest jb stock rom and tried to flash via odin..... fail! anything i try do via odin fails.
so lol i can get into download and recovery mode fine roms also install fine all data has been wiped!!! and reset thats not the issue here.
any help?:silly:
thanks, andy
Try superwipe. It will erase your internal SD, though

how? never heard of that and the phones been totaly wiped
It sounds like your sudden power off has corrupted either the SD, internal SD or NAND partition structure. Never a good idea to use all four cores + GPU with less than 15% battery remaining.
Flashing a superwipe script via CWM will do the same as formatting the system, data and external & internal SD in CWM. This might help before flashing a stock ROM but you may also need to restore the partition structure, search and read on this subject here on XDA.
Ok I super wiped and now it loops at the galaxy sIII logo..... argggg.... off to read up on that other method u mention.

Hi there,
i tried a lot of word combinations to get a thread with my specific problem but i didnt manage it to find one.
So here is the deal:
i have german galaxy s 2 (9100, bought in september 2011) and i flashed it last year with darkyrom HD something gingerbread-style.
so it was rooted and all that stuff.
it worked pretty fast and it was stable and it looked sleak.
Last year in November i put Ressurrection remix 3.x (dont know which version of it) on my phone.
It had a lot of crashes, freezes and while playing ingress it always drained around 20% of the battery within 10-20minutes.
So i stopped it. I put the last version of it 3.1.3. of it onto my phone with a full wipe, cache partition, factory reset onto my phones and the problems went keep going.
As an example:
-I couldnt access options where i can select ringtones or to see what is on the sd. it crashed and went back to the "main screen".
-Yesterday i tried around 15 roms, and nearly everything except militant rom keep crashing while iam installing them.
-Sometimes it crashes already while iam installing the rom, sometimes its after a couple of hours, that i cant access the rom any more.
-The newest problem is, that sometimes the power button doesnt respond, when i push it (in jelly bam)
Please explain, what iam missing or is my phone just broke?
It never fell down, no water or anything freaking other things.
I hope you can help me.
should i send it back or what is wrong?
i dnt knw bt samsung.. bt may b it happens coz of when ur changing ur rom gb to i cs or jb whole operating system is diff so u hav to format ur sd card to make it working.

i thought the kernel is already included when you're installing one of the roms?
which one should i take?
or how wipe the whole system to have it like "out of the box"?
flash a stock ROM and see how it behaves.

if you are rooted, you can try flashing NeatROM lite 4.2 based on LS8 and see how it behaves else flash official JB 4.1.2 using odin.

ok, ill try that right now..
if not using odin and try to do something with my nand???
after cleaning and putting a stock rom on it and afterwards rooting it with cwm still the same problem: boot loop or while the first installation, it crashes.
so what to do?
just hang around with the stupid official one?
If you did everything from Factory reset to changing kernel, and everything is still bad like that. I think that there's something with your phone's hardware.

after flashing the ROM via odin, reboot into recovery, wip/factory reset and then go in to mount & storage, make sure system, data and sd cards (internal & external if any) are all mounted if not mount it and reboot.

just as an example, when i tried to put on the neatrom-lite on my phone, it crashes while iam selecting the country. and this is just 2-3seconds after booting into the fresh and new system.
something is completely ****ed up....
so right now, i have the militant rom on my phone, got booted up, but the power button doesnt work.... when the phone is on...
so everytime, when i want to switch of the screen, i have to wait, or take of the battery. and switching on is only possible with the home button.
whats wrong?
Given you have the same problems on stock, hardware problem. Back to stock, reset counter, send it in for warranty service (if you have warranty), if not, take it to local mobile repair shops.
reseting the counter... with stock? how to do that? i thought this is only possible with root? and i thought, as soon as i root, there is something already on the counter?

You have two option. Either flash a custom kernel (siyah, for example), then reset the counter using triangle away app. Then flash a stock firmware using odin. This wont increase the counter.
Or, if you have a USB jig, flash an older bootloader (have to careful here), then simply plug in the jig.

hey, i got the problem:
i transferred a few files between the sd card and the internal storage of my device, and i realised, that the device is not able to fully transfer the files. it says after 40-50% that its done. is there a flash the roms via ODIN? or how to do that? just put the rom.zip as PDA?

Unzip first.
I'd advice you to read about flashing with odin and watch a couple of videos on youtube before you put yourself up to it or else you're gonna have a bad flash, and that means trouble.
