[Q] After flashing custom rom, N7 gets stuck on boot screen.

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,

[Q] Upgrading from 4.2.2 to 4.4.2

Hi everyone,
I'm planning on upgrading my Nexus 4 to KitKat.
Currently I'm using PA 3.69 (4.2.2) with Franco Kernel and CWM Recovery.
1. What files do I need to flash for the upgrade, possibly with links? (I'm going for Purity ROM)
2. In what order should I do the flashing process?
3. Should I upgrade CWM before flashing, and if yes, which is the latest version that supports 4.4 and how does upgrading work?
Thanks in advance

If you want to install stock KK, you can download the factory Occam images and install via fastboot.
If you want to install a custom rom, you may need to update your recovery to the latest version and flash a KK rom that includes an updated radio and boot img.

So you think I can:
1. Upgrade CWM to 6.0.4.5 here: http://forum.xda-developers.com/showthread.php?t=2198942
2. Flash this: http://forum.xda-developers.com/showthread.php?t=2545838, since it includes Bootloader and Radio.
3. Flash this: http://forum.xda-developers.com/showthread.php?t=2281607 (Purity ROM)
4. Flash any desired Kernel (e.g. Franco) and use Titanium backup to restore my apps?

U just have to download the Rom. Install it. Set it up. Then boot back into recovery and install the kernel
I don't think u have to update CWM. So just steps 3 and 4

I'm asking cause I am coming from 4.2.2 with old radio and bootloader and I want the most up-to-date ones.
And I am sure that just flashing the rom will cause problems... What do I need to wipe prior to flashing?

I checked the links. Your method seems to be OK.
As for wiping, you need to wipe data, cache and dalvik cache from the recovery when you flash the Purity Rom

Everything has worked flawlessly. Thanks!

The correct procedure to install CM

I tried to update my Defy+ MB526 at a newer version of Android (Jelly Bean or more... now it's running with the factory 2.3.6 ) but I have a problem with the installation of CM.
1) I rooted my device with Framaroot "Super SU" and checked wit "Root checker" and it is ok.
2) Then I stored in the SD the CM file.zip (before the 10.2 and after the 11) and the Gapps.zip.
3) I installed the SndinitDefy_2.3.apk
4) I ran the recovery mode, wiped factory/data, wiped cache partition, wiped Dalvik cache
5) Then install zip from SD card, but the file "cm-11-20131229-nightly-mb526.zip" and also the "cm-10.2-20131020-nightly-mb526.zip" aborted the installation with "error status (0)".
I dont' know why.
Please tell me if the procedure I've done is correct. Otherwise write me the correct steps. Thank you. :good:
Ps: system version: 45.0.2310.mb526.retail.en.de
build n°: 4.5.1-134_dfp-231

Flash this - http://forum.xda-developers.com/showthread.php?p=48501247, then reboot and go to recovery again. Then flash CM.

Thank you Hotdog.
I tried with flash the Sndinit and after, by the custom recovery, I've flashed the Twrp. After I've started the Twrp recovery and flashed the CM11. It seemed ok but when I rebooted the device to install the Gapps, it has gone in infinity loop.
After that, i made a mistake because i did a completely reset of the device (the total wipe) and after I've reeboted the Defy and it bricked!!!
But with the guide in this forum I un-bricked it (It isn't difficult, it's easy) and then I tried, by the same previous way, to install the CM10.
With the CM10 it works awesome (4.1.2) and the gapps didn't create any problem!
Thank you again and many thanks to all people that everyday helps each other in this forum (especially non-expertised like me!)

Updating from rooted 4.3 to 4.4

I'm currently running an LS980 with a CM10.2 nightly with TWRP and either ZV8 or ZV7–they both have the same baseband? This was all the latest and greatest as of when I updated in December.
Now I'm trying to just to a decent CM11 or Pacman ROM, but I'm getting confused as I wade through disorganized threads with people with questions not related to my setup. There's a whole mess of downgrades and autorec and ioroot and other tools that I don't know if I need.
So I have CM10 and old TWRP, what do I need to do for a stable CM11?
Thanks a ton!

1. Download your rom and Gapps (usually provided on the rom thread)
2. Copy your rom and Gapps to your internal sd card (on your phone)
3. Boot into recovery
4. Wipe Data/Factory, wipe System, wipe dalvik cache
5. Install your rom first, then Gapps
6. Reboot
7. Profit !
As long as you stick with CM or other aosp-based roms, you're good to go. You don't need to do fancy things to have a working kitkat rom with root and recovery.
If you want a Stock KitKat rom, then you're going to need IOroot 2.5 to root your G2 and then use AutoRec (provided by cloudyfa) to get a working recovery.
That's it !
Edit: think about updating your recovery beforehand, it won't hurt and may save you from going back to square one

Nobody can help you if you don't provide the exact error. From my experience, I think you need to edit and remove the assert() line from the updater script. Alternatively, you can try this-
1. Make complete backup of you current ROM using TWRP.
2. Wipe Cache, Dalvik, System, Data partition.
3. Now instead of flashing the new stock ROM, go to advanced options and choose reboot to recovery.
4. Now, again your phone will not into recovery; and this time you should be able to flash the ROM.
