[Q] Lenovo A1 not booting after Installation of CM 7 - Android Software/Hacking General [Developers Only]

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.

[Q] Accidently Wiped system and almost everything using Team Win Recovery Project v2

Was trying to flash the ICS ROM V5 but it got stuck on the boot animation. I did a factory reset, surprisingly it was still there. So i used "Team Win Recovery Project" aka "twrp-crespo-2[DOT]0[DOT]0RC0[DOT]img" in nexusshacks.com. I went in there to do a factory reset but i wiped the ACTUAL system instead. So when i reboot i am stuck on Google. Unfortunely i only had 1 back up which is in ClockworkMod, but i cant access that. I dont mind my lost files because i can recover that but i want my phone to work again. Can i copy the nexus s contents from another nexus s and place it in my SD and will it work? If you guys have ideas please do reply because i need my phone fixed asap. Bootloader unlocked and rooted using superuser.

okay,am not very familiar with TWRP but your problem doesn't seem that big,you wiped the /system which should not affect your USB storage data (even if you wiped the USB storage it's not a problem),try to boot into the bootloader (volume up + power button) then go to recovery,mount the USB storage and put a ROM on it,then just flash the ROM and your device should boot up normally,i think you weren't stuck at the bootanimation since when you flash a new ROM the first boot could take from 5 to 10 minutes.
i usually do a clean install before flashing a new ROM (format system,data,cache,boot) and the device just boot up normally after flashing the new ROM so it's not a problem if you wiped your system just flash a new ROM.

I did this same thing a few weeks ago. I just had to reinstall everything (including the recovery) from fastboot. Worked like a charm.
I used the nexusshack tut to root my nexus had no problems.
You could go into recovery, mount usb storage, find the clockworkmod directory and copy that to your pc..
do a full data wipe and flash a new rom, then install rom manager flash CWM recovery . move the clockworkmod directory back to your phone. boot into recovery and restore you backup.
Just an idea .. not sure if it could work..(take no responsibility is it doesnt)

Hello, my phone detected that there is an update then i click the update after that it told me to confirm for reboot my phone enter CWM recovery then I clicked on reboot system now. It showed the Samsung Logo and the Splashscreen, but then enters the CWM recovery. I also tried pulling out the battery and then pushing the power button, but it still boots into CWM recovery.

"Encryption Failed" - Phone Will Not Factory Reset

After searching through countless threads on this site, I've had no avail in resetting my Rogers Samsung Galaxy S6 running XtreStoLite 2.2.
A little while ago, I thought it would be a good idea to encrypt my phone with a custom ROM installed. I knew I had recovery and download mode, so I thought It'd be no biggie. Left the phone on overnight encrypting, came back 24 hours later and knew that it hung somewhere. Booted it up and this screen came up: Reset it and restored from TWRP backup, the same screen right here came up: http ://i.imgur.com/J37aZaq .png (sorry XDA will not let me post links, remove spaces) after this, I tried pressing the "reset device" button without success. It just rebooted the phone. Tried to restore from a different backup, no avail, then I tried to flash my custom ROM again through TWRP, no avail. I download ODIN and flashed stock Samsung firmware onto it and it still gave me this screen when I was done. Tried going into TWRP and factory resetting (where it wipes all partitions) and nothing happened. Currently, I'm trying to flash my Samsung Galaxy S6 with the stock firmware through ODIN with the "re-parition" box checked.
It seems there's a hardware flag of some sort stopping this from working. I mean, my file system is brand new, reset to factory defaults, I even checked with ADB and everything has been formatted. Checked with TWRP file manager and everything is good. But I can't get past the "Encryption Failed" screen.
Help me! Thanks.
fix
did you fix this?
Hi, i am encountering the same problem with my G920F.
I have the XtreStoLite_Deo_Mod_v.2.3 and also TWRP installed
I started encrypting but it got stuck so i rebooted my phone and got the same message (Encryption failed, please do a factory reset). So i did the reset but the same screen appeared. I also tried restoring from a back-up from TWRP but the same screen was still there. So i decided to do a full wipe and restore the phone with a twrp back up witch was on my laptop. But when i am in TWRP i can not copy files to (or from) my phone. So it is not possible to get the backup on my phone. I am able to get in to download mode and connect the phone with odin.
My questions are :
- what was the solution to the problem?
- What causes the copying error? And what is the solution? So i can put the backup on my phone and try to restore it this way.
- What are my option with odin? Can i use the TWRP files in odin?
Thanks a lot in advance
Jules
Solved the issue. After a full wipe i installed a stock firmware with odin. It still displayed encryption failed after reboot. But after the factory reset the notification was gone.
I have fixed this
Best solution is on a stock rom to reset. If rooted with recovery -format and wipe all data, reset, let sit at boot for a while, go into recovery and install new rom from USB-OTG, or odin from download mode.

Encryption unsuccessful

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?

[Help] Flashed Franco Kernel over CM13 Stock and ended in bootloop

Hi, so short story is.
1. I had a backup of my stock rom that i did using twrp.
2. I flashed Franco Kernel for COS 13 downloaded from his website (https://kernels.franco-lnx.net/OnePlusOne/6.0.1/anyKernel/)
3. When i flashed i performed a Wipe dalvik cache from recovery
4. Reboted phone, and started optimizing apps but suddenly it rebooted.
5. Started optimizing apps but when it showed optimizing app 1 of 103 the phone keept restarting.
6. I decided to restore my backup made from TWRP, but then phone got stuck and restated everytime from the CYANOGENOS logo.
7. Since it was not booting, i decided to install from fastboot a clean CM13.
8. Flashed, finished and then the phone restarted, but heeey, again stuck in the CYANOGENOS Logo and restarting when the logo shows up.
9. I freak out and I don't know what to do.
So far:
fastboot is working
Cyanogen Recovery is Working ( tried the wipe from that, but still no luck)
When I plug the device directly to my PC, it shows "QHSUSB_BULK", but as i say: fastboot and COS recovery are working.
Can you guys help me, please
First of all, I let the phone charge till 100% on screen (yes, the charger indicator was working aswell)
Well, since my device was able to boot into both Recovery and Fastboot modes, I decided to flash a custom recovery one more time to replace the COS recovery. I flashed CWM 6 (because before TWRP was not helping) and performed a "backup" of the whole rom, just to see if it worked, and it did. After that, i wiped /factory reset from CWM.
Rebooted the device, and voilá I guess. The phone was able to boot into CM 13, now I'm happy to see that I was able to recover from this issue.
Still have no clue about why the FrancoKernel ended in a bootloop. Was the cache wiping a bad idea ?

Yes,that's where it all went wrong.You should never wipe anything while flashing a custom kernel.
