Hi guys, I got a SGS2 just over a week ago, on Bell/Virgin network in Canada. Suffered from the battery drain issue due to being stuck with crappy UGKG2 firmware which my provider still hasn't updated.
I decided to update it myself, and did a ton of research. I successfully got Root tonight by flashing CF-Root-SGS2_ZS-OZS_KG2-v4.1-CWM4 kernel with Odin. In case it matters, I did NOT flash back my stock Kernel, so I still had the insecure kernel installed. From there, I backed up my apps with Titanium.
Went into CWM and selected boot into CWM Recovery. I followed the steps on the wiki, including creating a backup file. My only hint of what I might have done wrong was I originally selected to flash update.zip, and that process failed. I then went to the directory in which cyanogenmod is stored on my SD card, and selected that, then it installed ok. I had downloaded update-cm-7.10-GalaxyS2-signed and that's what I put on the phone. I then also installed the Google Apps.
I then hit reboot, and it only goes to the Samsung screen with the yellow triangle and just hangs there for a few minutes. Not knowing what else to do, I popped the battery out. I have since learned that I can turn it on and off, but it never goes past that screen. Wouldn't go into the recovery or download modes, always that screen. Luckily, I saw somewhere to do the 3 button thing WHILE in that screen, and that works. So I can get to recover, and download modes. So, I think I'm ok. I checked, and it does connect to Odin still.
I just want to know EXACTLY what I should do at this point. I don't want to fully brick it. There are actually two recovery files on the phone... not sure why... Or which one to pick. Should I just flash stock firmware back with Odin? One of my main goals is to get off 2.3.3 so I can have more than 8 hours of battery...
Thanks,
Rob
Boot into tecovery, do a full wipe again. (Wipe data/factory reset, wipe cache partition, advanced>wipe dalvik cache).
Now install CM7 zip twice in a row without reboot. It may take a few minutes for reboot since system is rebuilding dalvik cache. Be patient. After you see the home screen, reboot again.
Sometimes, CM won't install properly with CF root recovery. In that case reboot into download mode, flash codeworkx cwm kernel via ODIN.

Now reboot into recovery and do full wipe and twice-install !
Ok, working now with the flash twice thing. Well that's weird, would be great if it was in the wiki page...
Thanks!

I just flashed the new CM7 ROM onto my Atrix. I was running the Dark Side ROM before the flash. I tried booting my phone up, it goes to the boot animation which runs for about 5 seconds, then reboots. Its cycled for 10 minutes. I pulled battery, reflashed, but the problem seems pretty persistent. Any Ideas?
it may be obvious but did you do the "3 wipes" before flashing CM7? also try "fastboot -w" if you've done wipes in recovery already before flashing
i am having a similar issue with the MOD 2 version of this rom, i was using my atrix with the hdmimirror.zip that i installed other than that the phone was just stock rooted, with an unlocked bootloader. now that i have flashed this rom ( doing all the necessary wipes and etc.) when i try to reboot i am stuck at the dual core screen. any thoughts?
Format the system partition, factory wipe/reset, wipe dalvik cache. Reboot into CWM and then go ahead and flash the ROM. That should hopefully make sure it's all clean before the install.
I just did the biggest F-Up of my flashing life. While following QBKing77's Rooting & CWM with unlocked, at approx 3:50, during the flashing of the root SYSTEM.img file, rather than that file, I used the wrong file to flash used an IMG file that was meant for cwm, which is a completely different task.
So now I am trying to get into fast boot and try to do it with correct SYSTEM.IMG, then to find out I never got it downloaded, the link was deadand now I can not find where to DL it from. I must've not been paying attention and got ahead of myself.
Anyone know where I can a mirror of the file found here. Its the first link in the root section labelled "moto-fastboot flashable /system image".
Am I screwed? Does anybody have a copy of that system.img file laying around. I can not find any mirrors. That is the only way I can see this getting fixed bc I can still go into fastboot mode.
ckeck this ????

Can u get into rsd mode and flash 154_5 sbf
Sent from my MB855 using xda premium
Important files
Thank shabbypenguin for those
If you can get into rsd mode and connected/recognized in rsd lite you should be able to flash one of those sbf files and return to stock.
I read the instructions carefully! It said to put the oven on 350 degrees for 10mins but for some out of this world reason I put it on broil and let it cook for 20mins :/

LOL no kidding Custodian. I did get a laugh out of that.
Thanks CubanLuke & ShabbyPenguin. I did use RSDLite to flash the current sbf you directed me to, I can boot into the phone again. Thanks again.
Now as to how to proceed, I will have to unlock the bootloader again, np, but when I run into that very step where I broiled it, the rooting via speedboot.... would it be okay to root using AIO instead because I can not find the SYSTEM.IMG needed to follow along w/ the video using this method.
Can I just root a different method, then proceed on with CWM recovery, then flash rom from the video?

Thanks KTT. Okay, I'm back on track now. I am unlocked again, rooted as well. but I am not sure about 2 things. This will be my very first android rom flash and just coming from a big whoopsies, I just want to be sure.....
1) Format system: in cwm recovery, which option is that? I don't see "format system" in the main or advanced menu. Maybe its worded differently?
2) Flash ROM: I can only assume its either "Apply Update from SD" or Update from SD". Not sure which one though.

1) Format system is in the "mount" options. Although it's unneeded to flash a ROM. Personally I just wipe data/factory reset and then wipe cache and have zero issues. Others may tell you different though.
2) "Install .zip from SD Card" then select whichever .zip you're looking to install.

Okay well I am in some trouble again. successfully flashed an alpha cm7.1, but it didn't have market and the one i installed did not work so decided to flash to cm7.2 via CWM. When it booted I didn't really see anything change, later realized that maybe I was suppose to wipe/format in cwm first(idk).
So I decided to flash 198_7, same one that I used to restore back to stock earlier. But I did not get back to stock. The process was 100%, it told me to manually turn on the device, which was in rsd mode. So I unplugged, pulled batt, reboot. The phone now starts up until the pulsing Moto logo then screen goes black, then it loops.
In the process I lost CWM & unlocked. So trying to flash a ROM via cwm is no longer an option. Any thoughts?

Flashing the 198_7 sbf unroots and relocks, so you're back to square one.

Reboot into stock recovery, when you get the recovery logo thing push both volume up and volume down at the same time to get the recovery options. Then do a factory reset and it should boot for you. After that, root and unlock again. And you didn't have the Market because you forgot to install Gapps...

The reason cm7 didn't have the market is that you needed to flash gapps. Try doing a hard reset. http://www.hard-reset.com/motorola-photon-4g-hard-reset.html That should do it.
try the 154 sbf

i had the same problem i think and was going thru boot loops but some one told me to start into recovery when you try you get that ? android screen from there hold down volume up and down at same time then wipe phone booted up fine after that.
It worked like a charm. Thanks. I'm still very new to android and hate to admit it but will be running into problems like these again. The best way to minimize it for me is, not only follow certain directions correctly to get out of these binds, but to understand them.
- So theres an image of the stock ROM stashed away on the phone regardless? And it can be accessed only via the stock recovery? Because after I succeeded in flashing cm7.1, I did a factory reset once from settings>privacy and that restored me to a fresh CM7.1. The factory reset from settings>privacy and in CWM is the same, but both different from the factory reset via STOCK RECOVERY?
- Also what would be the correct method to go from one custom ROM to another? Would it be this? :
(in CWM)
- Format system
- Wipe data/factory reset
- wipe cache/dalvik
- Reboot recovery
- Flash ROM
Or can I just jump to install from zip ?
- Also regarding SD Storage (internal), only holds storage files? So on any fresh ROM there shouldn't be anything in that partition relating to that new ROM yet right? So I can delete things without worry?
You should not have to reboot into recovery, once your wipes are complete, normally you can just flash your ROM of choice in the same recovery session.
Before I flashed anything I would make a backup with CWM so you don't have to keep rooting and unlocking. You can just restore your backup.

After flashing 198 7 sbf, all u need to do is flash derpunlock not go through oem unlocking, then reflash recovery.
Simple generic process for going between roms (assuming already unlocked + cwm recovery flashed; process may be different for some roms, always make sure to read directions, but this is the general concept)
1. Download rom (and gapps if necessary) and put on your sdcard
2. Boot into recovery and make a nandroid backup
3. You made a nandroid backup right?
4. Secure your nandroid backup (move it to your pc or something).
5. You know where your nandroid backup is right?
6. Wipe data/factory reset.
7. Install zip from sd (flash), choose the rom.
8. Reboot system.
At this point your rom should be all set. If for some reason you don't like it, simply boot into recovery and restore your nandroid backup. You can even make nandroid backups of various roms if you want to swap between them for whatever reason.
hi everybody.
my phone is booting every time. with odin i installed already twrp and cwm. with twrp I can just see the logo and then the phone is booting again. with cwm, i am able to see the menu but when i try to wipe the phone, the phone starts to boot again.
i installed cyanogenmod via adb but the phone is not starting android.
the last chance i have is to hope that someone of you have a solution.
i uploaded a video to show you what i mean.

Have you tried flashing a stock ROM?
yes. but it is still in the loop.
Flashing in Odin was successful?
After flashing the stock ROM, did you perform a factory wipe before booting for the first time?
thats not possible. i can boot to the clockworkmod recovery but if i choose the option "wipe data/factory reset" the recovery will be closed and the smartphone boots again and open the recovery.
1, download mode and flash an official stock rom (one package) via odin. Make sure it is for your device specifically.
2, Boot to official stock recovery and wipe data/factory reset. If the phone reboots after this you need to be prepared to key combo to download mode BEFORE it boots android.
3, Flash the official stock rom again.
All remnants of any previous roms will be gone and you should have a booting phone.
Beamed in by telepathy.
It worked with the stock recovery. Now I was able to install cyanogenmod. Thank you very much!!!
