[Q] After flashing custom rom, N7 gets stuck on boot screen. - Nexus 7 Q&A, Help & Troubleshooting

After rooting my N7 a few weeks back, I have tried flashing at least 3 different grouper custom roms through TWRP 2.4.2.
After flashing the rom, when I reboot from TWRP, the N7 gets stuck on bootscreen logo of the respective rom. I have to use Nexus Toolkit 1.6.3 to reboot into TWRP and restore from nanroid backup of stock rom, and everything works fine.
Why are Custom ROMs not being able to boot past the bootscreen logo?
I would appreciate help.
Thanks in advance.

You should give us more info... What's your device, which rom you want to try, what steps did you do to flash the rom in recovery?

Nexus 7, I have tried flashing simbean 4.2.2, latest XenonHD and another which i have forgotten the name (all latest grouper versions).
I downloaded ROMs on my PC from XDA.
Copied zip file into nexus 7 via USB cable.
Rebooted into TWRP 2.4.2.0
Wipe System/ cache/ dalvic cache
flashed Rom (indicated flash was successful)
Rebooted from TWRP
bootloop (getting stuck at the bootanimation of the custom rom)
Used Nexus Toolkit 3.6.1 to reboot into TWRP
Restored my stock rom from backup.
Stock Rom working fine.
Ive tried flashing faux kernel and an aroma installer for boot animation change, which has worked fine both times.

When you are in recovery, first go in wipe menu and do a factory reset, wipe system (optional), install the ROM and reboot and all should be fine.

Maybe try flashing with a more recent version of TWRP, 2.4.4.0

--------
Fastboot flash the latest recovery image from here...
http://techerrata.com/browse/twrp2/grouper
...and then try again, flashing your preferred ROM in recovery.
--------
Don't know if it will work... but it's got to be worth a shot.
What is odd, is you seem to have no problem NANDROID restoring back to stock...
Anyway, hope you get it sorted.
Rgrds,
Ged.

My backups are not working....

Ok so first off I was successful in rooting the phone, installing twrp rec., flashing loki files, and then flashing wicked rom with ktweaker tw kernel. I made a backup of the stock rooted rom before wicked was flashed. Then my troubles started when I wanted to go back to my stock backup. The rom booted but has serious issues like black screen with only status bar working and then eventually freezing. I also made a backup of a working wicked and tried restoring that but then I just get stuck in boot loop. Any help would be greatly appreciated.
what twrp version
did you wipe all before restoring
you could try to install Phils cwm recovery, folks say it works great and will restore twrp backups also

Follow full wipe procedures, have the same recovery you made the backup with, and try again.

I flashed the stock firm. Soft brick averted. Did the same goo manager recovery method, but now i'm thinking of flashing that cwm as ppl have reported the same nandroid backup issues with twrp. My version is 2.5.0.2. I will keep trying to get twrp for a while with others users till i get sick of it (semi twrp fan). Any further advice would be cool. Oh and I did a factory twrp wipe the first time this problem occurred.
I wipe data caches and system before flashing. No more advice. Had newest TWRP hang on Team Win screen. Several manual reboots into recovery till it worked. Maybe I better do restore to see if it works.

[Q] Custom Recovery Doesn't Work Anymore

Hello,
I've rooted my own note 3 and flashed Temaseks unofficial cm 12 rom. Everything works perfect so I decided to do the same thing for my father. It all went well, first I rooted his phone, then I flashed CWM and flashed cm 12 by temasek. The rom works fine but I forget to install the Gapps. So I tried to install Gapps but I got an error "Failure Status 6". I googled on that error and someone told it has to do something with CWM. I tried to flash a different version of CWM but now I can't reboot into recovery mode anymore. So I can't flash anything.
I flashed another version of CWM but this one also doesn't work. Whenever I try to boot the phone into recovery mode, the blue line shows up. Rebooting into recovery mode, but after a few secs, the phone just boots the normal way. Is there anyone that can help me to get CWM back to work? In the mean time I'll try to flash TWRP by Odin.
Thanks in advance!
So I flashed latest version of CWM: Buildversion; 6.13.0, CWM Base Version V6.0.4.7. I can reboot into recovery now but still can't install Google Apps due to failure status 6. On my own Phone I run a different version of CWM, but when I try to flash it, the phone won't boot into recovery mode anymore. It only boots into recovery when I flash this V6.0.4.7 . How can I get rid of this version and flash an older version of CWM?
You'll probably have to Odin back to stock and start over...

You mean If there is no other way to get the Google Apps on the phone, I have to go back to stock. I did make a backup with CWM on the while it was running custom firmware. Now I have 4 files on my comuter, 3.tar and 1.md5 . If I recover them, I will still have this not working CWM version on my phone right? Isn't there a easier way to delete CWM, can I flash TWRP over CWM and see if it will install these Gapps?
Yeah, you should be able to flash TWRP over it. TWRP is much better anyway, in my opinion. Once you get the recovery issue sorted, I really wouldn't't recommend trying to flash just the gapps. It would probably work, but it's also quite likely to cause some weird issues. It's always best to flash gapps immediately after flashing a ROM, without leaving recovery.
I would flash TWRP, wipe everything but your internal SD, re-flash the ROM, flash the gapps, and everything should be cherry.
Edit: here is the link to download TWRP.

I appreciate your effort, thank you. The recovery issue is solved. I flashed Chainfires Root script and that installed the stock recovery. However, when I tried to install and older CWM version I got back in the recovery reboot cycle. But once I installed the latest CWM it booted in recovery. So I flashed Chainfires Root once again and had the stock recovery back. From there on I tried to install TWRP but got the recovery boot cycle again. My phone is now running android 5.0.2 and I think that's the problem.... :S I'll try again to flash Chainfires Root script to get the stock recovery back. From there on I will try to flash the link you gave to me with Odin and hope that will fix it. Do you have any ideas on what I'm doing wrong?
Your version of TWRP works so far. It reboots into RecoveryMode. Now I'll wipe and try to install Temaseks Cm 12 followed by Gapps! Thanks so far!
Okay, it's solved. Can't thank you enough for you help. Bless you!!
No problem. Glad you got it figured out!

Phone only boots into TWRP

I decided today to try and root my phone and followed the steps on this tutorial: http://forum.xda-developers.com/nexus-4/general/nexus-4-guide-unlock-bootloader-root-t2266654
I had unlocked my phone and installed the latest version of TWRP. Now I can only boot into TWRP and bootloader. My phone is not being picked up by my PC. I tried a factory reset and format of data on TWRP but my phone still only boots into TWRP.
Is my phone permanently bricked?
Any help will be greatly appreciated
I actually have just made some progress now. I've managed to get the phone connected to the computer by going into ADB sideload and installing the ADB drivers again on my computer.
Typing ADB devices in CMD now shows my device as connected.
Any advice on what I should do now?
What happens when you try to boot it normally? Is it stuck at the boot animation or does it go directly to the bootloader or recovery? Since you already had to wipe everything you could try flashing a factory image via fastboot.

Booting the phone normally loads it into TWRP. Booting the phone with the volume key pressed down loads the bootloader. I think I may have just wiped the OS present on the Phone.
I want my phone to be rooted running CyanogenMOD (phone is currently unrooted). Should I first install a stock rom then root by installing SuperSU and CyanogenMOD or can I just skip installing a stock rom and install SuperSU and CyanogenMOD?
Thanks for the help
You could try flashing a cyanogenmod zip from TWRP, and if that doesn't work I would suggest flashing I factory image.

But my phone is not rooted yet. Can I install SuperSU by copying onto my phone and installing it through TWRP?

Yes, if it is a zip file. But I'm pretty sure installing cyanogenmod will automatically root it for you.

I installed SuperSU then CyanogenMOD and lastly GApps. It still only boots into TWRP and it doesn't look like there has been any files added to the phone's storage. Should I first flash a stock rom and then try to install CyanogenMOD?

Yes, try flashing a factory image. If it boots then you could try flashing cyanogenmod.
EDIT: here is a guide on how to flash a factory image: http://forum.xda-developers.com/nexus-4/general/how-to-how-to-flash-factory-image-t2010312

@hwweiler, No friend there is no other way.Please before do this as is one direction way take the pain to look on my post #180 on zaclmon's thread http://forum.xda-developers.com/nexus-4/orig-development/wip-aosp-7-0-nougat-t3448444/page18 and keep in mind that is impossible to return back on any nandroid backup u kept e.g to 5.1.1 or M furthermore its also impossible to flash any rom zip if u use this N (WIP) rom,the only way to have a workable phone again is to flash the stock rom from scratch.Exceperienced with and never again untill we have the appropriate solution..The twrp used and i still use on M is TWRP 3.0.2.0.The possibility to return on LP ffrom M and reverse still exists but not when u flash this rom.

TWRP not booting system

I tried to factory reset a custom ROM, got sent to TWRP then I can't reboot to system from there. Tried a clean install but to no avail. I've looked around on the internet and I think I have to reinstall stock ROM and then reinstall custom recovery and ROM, except if I were to install the stock ROM once again (with sp tools) I need my phone to be turned off, not in recovery mode. So how exactly should I proceed now?
EDIT: Managed to get rid of the TWRP bootloop by restoring from a stock nandroid I've found on the forums, coupled with flashing a stock recovery image using TWRP. Reunlocked bootloader, flashed TWRP all over again and then flashed custom ROM and Gapps. Everything running fine now.
Mods feel free to delete this post since it's solved itself, or leave it in case anyone needed help concerning the same issue, up to you.

Did you try to flash a stock firmware ? To install Rom you need the latest available stock firmware (because it contains new versions of Modem & stuff). Then wipe system/cache/dalvik-cache/data and flash your Rom.
This happend to me one time on a phone, I did not have the latest stock firmware before flashing Rom and my phone bootlooped to recovery.
