[Q] Custom rom in bootloop ? - Nexus 7 Developer Discussion [Developers Only]

I have build from source CM12 and when I flashed the ROM it is in an infinite loop in the GOOGLE logo. I have done everything correctly.
I installed a CM12.1 build and there is no problem.
Flashed factory images of 5.0, 5.02 an 5.1.1 and then flashed my build but still it is in loop. No problem when I flash a CM12.1 build.
Can you point out what I did wrong ?

If you built from source with no modifications, it should work fine provided that you are installing it on top of the same version of Android. That means if CM12 is 5.0.2 you probably have to install it on top of a fresh install of stock 5.0.2 or some 5.0.2 ROM.
You should also wipe data and dalvik (you probably did seeing as you claim to have done everything correctly).

Here ist what i have experienced:
I was on System Version: 181.46.3
Well nevertheless:
It was the most recent version i could get and i wanted to get back to Android L.
I installed CM12 the Following way, I had a lot of problems with that. So here is my experience and everything:
So you need to know, to install CM12 or other CM12 based ROMS you first need to have CM11 installed.
Newer Versions of the recovery might be having problems installing CM11, so i would recommend using PhilZ Touch Recovery. It was working for me.
1st: install PhilZ recovery
2nd: factory reset
3rd: install cm11 (Unified Build, due to no up-to-date-build for XT925)
4th: boot
5th: install latest TWRP XT925/TWRP XT926
6th: factory reset
7th: install CM12 XT925 / CM12 XT926 or other CM12 based ROM
8th: install Gapps
9th: wipe cache/dalvik cache
10: Boot
11: Have fun.
Possible problems:
"This package is for moto_msm8960, xt907, scorpion_mini, smq, xt926, vanquish, this is a xt925" ------> You got a problem with the Recovery, it is too new. Try PhilZ
CM12 Booting, inconsistent Data partition stuff error ---------> you did not install cm11 and did not wipe Data before installing CM12, when coming from Blur Rom
Bootloop ---------> no wiping or you did not install cm11 before installing CM12
I hope this might have helped you.

Heyho
I have an XT925.
I installed the msm8960 Build.
The Reason i used the unified Build was, there is no KKBL build for the xt925.
thanks again, onto the procedure now
just last thing, which version of philz recovery you installed, download link has latest one @esok44

If you come frome OTA Kitkat 4.4.2
you have to change Step 1st: install PhilZ recovery ------ to ------ Install TWRP2710-RAZR-HD_M-KITKAT.img instead then you can flash the CM 11
If you like philz_touch_6.58.7-moto_msm8960.img recovery (it can mount external Memory Card as USB) you can flash it after all installations after Point 11. The only thing that you cannot start directly to recovery from CM 12.1

Issue while flashing android 5.1 roms

Hi All,
I have XT1033 Dual Sim (Currently running CM12 Official Build - Latest Nightly).
I tried to install Android 5.1 based roms like (Team UB rome and unofficial build of CM12.1). I alo flashed the Gapps (Android 5.1) I used Philz recovery to flash the same.
Flashing was successful. But when I come to the setup part then i got error "com.android.phone has stopped working" at language selection page.
After that i come to the wi-fi selection page. There i selected skip and i got error "Setup has stopped working". and it again redirect me to language selection page. I get stuck in the loop.
Could anyone please help me to resolve this issue on XT1033 Dual sim device.
Hmmm... Strange. You see did you have trouble flashing CM12? If you didn't, try a different recovery (providing you know how to install)
Sam.

I tried both Philz and TWRP recovery. Both of them giving me the mentioned error after flashing and the booting of ROM
Did anyone try installing android 5.1 rom based on CM12.1 in XT1033 Dual Sim.
If yes, could you please provide me the recovery.img file you are using for this.
Is this problem because of i am at CM12 and then trying flashing CM12.1 ROM.
Do i need to go back to Stock 5.0.2 and then try to install CM12.1 rom.

[Q] Stuck in Boot animation after flashing cm12.1

I managed to get my xt925 updated to KKBL, and after flashing cm12.1 I'm stuck in the boot animation. I tried flashing several cm11 versions as suggested somewhere else as step inbetween, but most of them resulted in boot loops (right after unlocked bootloader warning) Any Idea how to fix this ?
btw. I'm trying to flash the lastest cm12.1 . unfortunately I did not make a backup uf stock KK rom before starting this. silly me Is there a stock 4.4.2 ROM available to flash with RSDLite ? I Already tried to restart the whole process - but flashing Stock JB won't work after having KK BL

Fixed the Issue by flashing Slimrom 4.4.4 as interlude. Now I'm on CM12.1 and bootup process is normal.
Thank you, so much!

I was with the same problem and a fixed it after read your tip!! thank you very much!!!!
That is what did the trick for me too.
At first cm12.1 wouldn't run on my XT925. Then i flashed SlimROM 4.4.4, booted it up, rebooted into recovery mode (twpr 2.8.6.0), flashed cm12.1, wiped cache and dalvik and then rebooted.
Now it runs stably on cm12.1. Thanks a lot!

Lollipop ROMs will not boot up

So i've been running stable slimkat 9.0 (4.4.4) on my galaxy s3 and it has been working great. I want to upgrade it to lollipop but I've had trouble flashing any lollipop rom. CM12, AICP, OctOS, PacROM all fail to boot after I flash in recovery. The boot animation starts, and I get the screen that android apps are initializing. After it runs through the apps, the screen blacks out and the phone resets and the cycle continues.
I've had no issues flashing roms beforehand. I can go back to 4.4. and 4.3 ROMs both AOSP and Touchwiz without any problems. I've flashed with both clockwork mod and TWRP and the results are the same. I do a clean factory reset and wipe prior to flashing the rom and 5.1 gapps.
I have no idea why it won't boot up for me. Would appreciate any help!

Are you on the correct firmware? MF1? There is a flashable zip in the CM12.1 thread for it.
Updating the firmware did the trick, thanks! Was running on ML1 up til now. Glad my s3 can still keep up with the times

TWRP says "Patching system image unconditionally" for CM 14.1 nightly on XT1033

TWRP says "Patching system image unconditionally" for CM 14.1 nightly on XT1033
Hey I have a question please help me.....
I have an old Moto G (1st Gen Indian Retail Unit) XT1033. I have successfully unlocked the bootloader and installed twrp recovery. When flashing the CM 14.1 nightly it is stuck at "Patching system image unconditionally" for about an hour now. What might be the problem? I've searched a lot in xda forums but of no luck. :crying: Can anyone guide me through this?
Thanks in advance.

* When you boot into recovery, TWRP asks for write permissions? If it does, allow modifications and try to flash again.
* Also you can try to download the ZIP file again, maybe the download went bad or corrupted.
* When this happened to me I made a *very clean install*. This means, that before flashing the zip file you wipe all the partitions (cache, dalvik, system, data, internal storage). Then reboot to recovery again, copy the zipfile and the google apps from the PC over USB, then flashed both zip files and then rebooted without problems.
The problem that you describe also happened to a friend's phone but unfortunately for him, it was a faulty phone (internal storage was starting to degrade, eventually it stopped working).
Thanks. I am going to bed right now and try to do something tomorrow morning. Also, is root access mandatory for flashing custom ROM? I am currently in stock 5.1 ROM if that matters.
P.S. I was thinking that may be it could work if I go from 5.1 to 6.0 on the CM 13 and then go to CM 14.1. Would that make any difference than going directly to CM 14.1 from stock ROM running on 5.1?
Help Guys!! I can't get it to work! And also my twrp is not asking for any permissions.
My Bootloader is version 41.1A if that matters anything.
UPDATE: I flashed the CM 13 Snapshot and it worked. I am now going to try updating from CM 13 to CM 14.1
One doubt, I currently have no GApps flashed. Can I go ahead and update to CM 14.1 and then download and flash GApps for CM 14.1? Or should I flash GApps for both CM 13 and CM 14.1 separately?
Solved!! After installing CM 13.0 I was able to install CM 14.1 successfully. Sorry for the late post.
