hey guys,
today i took upon the task of rooting my first android device and installing cyanogenmod on it. i first installed fastboot and then clockwork for rooting. all went fine then i installed cyanogenmod. after the installation said it completed succesfully i restarted my tablet but now it just stays at the lenovo logo during booting. i still can get into the clockwork mod recovery menu. i already tried wiping data/cache both to no avail. i can also still boot into fastboot when i turn on the tablet and hold the vol+ button but it doesnt do anything.
i really, really hope i didnt brick on my first try, if anybody got ANY clue, i would be more than thankful
ok i fiddled around a little bit more and formatted /cache, /data and /emmc in hope of removing anything that might prevent my tab from booting. after that i got the stock recovery menu again from which i tried a factory reset. however, when the tab tries to install factory data it says it failed. luckily i have an sd card with cwm on it so i can boot into it again.
i think that somehow the files needed for a factory reset are damaged or gone. i will try flashing a new rom when i get myself a cardreader, i just used the a1 as mass storage until now.
My P5100 had CM10 nightly on it and was running fine until I upgraded to the latest version of CM10 after wiping the cache & Dalvik cache. After the upgrade I couldn't get Google Play to run even after wiping its data and fixing permissions so I tried to do a CWM restore. Unfortunately there was a fault restoring the Data partition and now my tablet is stuck at the animated bootscreen. If I long-press the power button it powers off but immediately restarts. There is no way to start in in recovery or flash mode. I've plugged it into my PC and the Samsung Android ADB interface is showing but the other references to the tablet all have a yellow triangle in Device Manager. I'm hoping some clever person can help me rescue the tablet with ADB. Thanks!

IF CWM is not working use Odin to flash CWM again then use CWM to flash CM10,
You may need to do a factory reset (full wipe) from CWM.
If all else fails use Odin to flash stock JB ROM

Thanks but Odin cannot see the tablet to re-flash the recovery.
Downlods mode
Then flash new firmware

That's the problem - I cannot access download mode
UPDATE - it just started in download mode! I can manage from here!!
Just for the record you can install adb on the pc and run the command 'adb reboot recovery'. This will force the tablet to reboot in recovery mode.

Jeez, this has taken up most of the day to fix. I came across many problems I have not previously experienced:
1. When the tablet was stuck at the boot animation and I tried to turn it off by long-pressing the power button it immediately restarted. The only way I could get it to turn off was by long-pressing the power button whilst it was connected to my PC.
2. Flashing the stock ROM with Odin appeared to complete successfully but it would never fully boot, it always got stuck at the black & white Samsung screen. Same problems turning it off as above.
3. Flashing CWM with Odin caused the tablet to reboot into the stock ROM which would not load, in the end I had to untick the "reboot" button in Odin, power it off then manually restart with the Vol- & power buttons.
4. The only way I could get a bootable ROM was by flashing CM10 with CWM. I tried to restore 2 previous CWM backups but on each occasion there was an error restoring the Data partition and I got stuck at the scenario at (1). The backups were made to the external SD card with CWM Touch - is the Touch version unreliable?
I would be really interested if anyone could shed any light on any of this stuff!
For how long did you let it install during the first reboot? It happened to me too, and it took about 10 minutes, maybe even more...
Also, did you try in the "Mount and storage" cwm menu the options "format system", "format data", "format cache" and "format preload" options, prior to re-flashing a ROM? I have read somewhere that for a clean install it's better to do this, as it really clears everything that could mess up the system between two different bases ROMs (like CM and stock).
What I do everytime is using in CWM these 4 "format" options, plus "wipe" system, cache and dalvik, then immediately after this I flash with cwm the new "zip" copied on the card. Then the first reboot is much longer than usual, as at this stage it installs the files, rebuild the dalvik cache etc.
Good luck

I think I gave it a good 20 mins to boot. When I got up this morning there was an error message saying that there was no room to install any more apps even though I had very few installed. Settings -> Storage would not calculate the space available so I figured that the partitions had become corrupted. I did the step by step format you described and reflashed & it all seems to be OK now.
I have a Samsung Galaxy Mini 2 GT-S6500. Its rooted and have CWM based recovery installed via ODIN-PDA.
It does not have terminal installed. Yesterday I downloaded a software name Quick Boot (root) from google play market and its icon is purple in colour. i downloaded such software because i wanted some apps like that to ease me in booting to other mode. So after installing i tried using it. So i tried the recovery mode button. it asked for SU permission and after i allowed it, it boot into CWM based recovery and i was very happy as i though it was a working app. But now, i restarted the phone millions of time but it just keep booting into the recovery mode again instead of booting back into the samsung android os. :'( i read and tried so called cold-boot but no hope, tried wipe factory data and wipe cache and wiped delvik cache from the recovery but still no hope. anyone can please help me? :''''''(
Hey there!
I have a problem: My wife's WIKO rainbow 3g suddenly showed this message:
She pressed the button several times, but nothing happened.
I booted the phone into stock recovery and tried to wipe /data, but then it says "mount /data error! Force format /data". It looks like it starts to format, but after a few seconds it ends with no message at all. Tried to reboot afterwards, but now it is stuck in the "Rainbow"-bootscreen.
Tried to update the phone using the WIKO software, but the phone isn't recognized anymore.
It's still on stock recovery, as it isn't rooted yet.
Is it possible to root the phone and install a custom recovery in stock recovery mode? Or is there any other way to make the /data partition accessible again?
Hi,
I had installed TWRP 2.8.5 on Galaxy Note 4. I did a factory data reset, and formatted all the system and the data partitions as my device was encrypted. I restarted my phone, and as expected it wouldn't be able to boot to an OS as I had formatted everything, but I was hoping to get into the recovery menu, but it just shows the TWRP splash image, and the screen switches off, it again activates shows a the splash image for a second and then goes blank, and does this again, it does not load into the recovery menu. I tried installing the recovery menu again via odin but experienced the same error. Can you please advise on what should be done?
Thank you
