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.

I officially upgraded to 3.0.2, unlocked and rooted my phone.
It was fine for the first few times I flashed multiple ROMs. But ever since I flashed Exodus, I keep having issues switching to different ROM.
A week ago, I flashed "Switch to OOS3_H2OSMMv7" zip and was able to flash Resurrection Remix, but today when I tried switching to CM13 or PA it gets stuck at flashing the ROM zip. I tried flashing the firmware zip again and flash the ROM, but to no avail. It won't flash any ROMs now, just stuck at recovery while flashing the zip.
I have a working fastboot and recovery mode though, so I'm trying to avoid flashing the entire factory image but that seems to be only option left. Does anyone have any clue as to why this is happening and how I can fix it?
Edit: Resurrection Remix gets installed fine, CM13 and PA still giving me issues.
Edit: I downloaded the latest version of CM13 and it works. Earlier I was using June 30 build which seems to have issues with the new firmware. I'll try out the new PA build to see if it fixes that too.
What error does your recovery gives?
Do you have Data Backup?
Can you access ADB while in Recovery?

It does not show any error as it just looping while installing the zip. I have to force shut down the phone to exit it.
Yes, I have backed up all my data
Yes, I am able to access my phone in both ADB and in fastboot modes.
After flashing Custom ROM, Wipe data, cache, d-cache and then reboot.
If still doesnt work try flashing another custom ROM. You can use adb-sideload to flash another zip in recovery mod.

Autorec is just the first step to twrp. Go to https://forum.xda-developers.com/lg-g2/development/twrp-twrp-2-8-0-0-kernel-f2fs-tools-t2898705 and get the bumped version 3.1.0-1.
Then put it in your phones memory, boot into twrp you got from autorec and flash the new version.

How did you flashed your phone? Your display have been black and you haven't seen anything. How did you entered into download mode?

Hi,
It seems I have the same issue :
I tried to install LineAge, using TWRP 3.2.1 (from CM12.1), but nothing is working (I tried 20180425 and 20180404 nightly versions). After reboot I can see the backlight on the lcd screen but nothing else. Then I tested the installation of a CM12 version, all is right, normal boot. No error message written in the console. i tried also a CM13 install, same as Lineage.
Do you think I have to flask back to LG "OS" ?

Are you clean flashing? Make sure to factory reset, wipe system, data and cache before flash. Never wipe internal storage. Swipe factory reset again after flash. Try flashing gapps later after confirming that Rom boots fine.

Hi,
yes I wiped Dalvik, system, data & cache through TWRP, before flash. But I don't wipe after, I rebooted without GApps...
Maybe, because I read that somewhere, I need to flash a bootstack. I don't know when I have to di it, if I have to do.
Thanks

Yes, you don't wipe after flash, but you swipe the factory reset, it does not wipe but resets the flashed Rom. Give it a clean shot again. Check MD5 of the all files you downloaded with original MD5 to confirm the file didn't get corrupt.
Boot stack flash not needed. Please read the first post thoroughly in lineage thread
"""
Requirements:
Custom recovery (TWRP or any other)
KitKat (KK) bootloader (included in the lg-devs LP bootstack)
KitKat (KK) bootstack minimum; Please read the entire FAQ for important bootstack information. Installation of bootstacks is NOT recommended.
Clean flash if coming from another ROM or CM 13 (no dirty flash, wipe system too check you bootstack(needen bump support)

Hi,
what do you mean by "you swipe the factory reset", I'm not sure what it is, either "give it a clean shot again".
Sorry I'm not very aware of all those processes ^_^, and I'm french so not very aware of some vocabulary words
Thank you
I'm using the xxxNolimits rom 5.1.3. When I try to do the procedure to update the version of the oxygen I can not. I downloaded the rom from the site of oneplus, 5.1.4, I make the flash in the TWRP blu spark latest version and when I reboot the message "no OS installed"
I do not know what to do, my oneplus only recognizes the custom rom if I try to go back to the stock it does not recognize. It's like I'm not flashing anything. MA does not appear any error during the flashing of the stock rom by twrp
Have you wiped data? You can't upgrade from xXx to stock OOS without wiping data. Try wiping data, system, flashing OOS, rebooting and if it starts, reboot back to recovery and flash kernel ?
Hello everyone, I'm trying to flash Havoc os 3.0 alongside with BitGaps, but it always ends up in a bootloop (I always wait one hour in the "android" boot screen). My device is the A205G with Android 10. I successfully flashed TWRP using the guide posted here in xda (also flashed magisk), then I flashed Havoc and BitGaps (wiping dalvik, cache, data and system first and then doing a factory reset), but ended up in a bootloop after rebooting to system. In a second try after reinstalling Android 10 stock rom I followed the steps shown in a youtube video (can't post link since I'm a new user) with no luck (still getting a bootloop). In a third try I just flashed the stock rom, then flashed twrp with odin and tried to flash Havoc without flashing Magisk at any moment, still bootloop. Any ideas or suggestions on what could be wrong? I've only flashed one device before with a custom rom so I'm not an expert in this area, any help will be appreciated.
