So I rooted my N4 while on 4.4 and installed a custom kernel for battery improvement .. it was francos kernel. I didn't unroot it ... then ...
Then I tried to update to Lolipop and it got stuck at logo. I've tried every flash I can find ... only 4.2.0 and 4.2.2 will take. Then after adding a sim and rebooting it gets stuck on logo again. Or if I click the OTA update it gets stuck on logo.

I've tried a lot of options in the nexus root toolkit.

Maybe I have the wrong radio or kernel for anything beyond 4.2?!?!

Please, any help would be appreciated.

BTW: when I attempt an OTA update from 4.2.2 to 4.3 it gets stuck at "Android is upgrading ... starting apps"

I think the baseband/radio is not flashing when I do "flash stock + unroot"

Any help?

Are you using the correct bootloader?
Many ROMs don't come with the bootloader and radio image. Even flashable stock ROMs.

If you want the latest lollipop I suggest this thread
http://forum.xda-developers.com/nexu...e-rom-t3084656

When I set up my device from scratch I did the following:
- format system, data, cache, dalvik in TWRP
- flash bootloader in TWRP
- flash radio in TWRP
- flash ROM in TWRP
- flash SuperSU in TWRP
- reboot

First reboot can take really long (up to 10 minutes may be normal still).
