[Q] Updating modem on z3c? - Xperia Z3 Compact Q&A, Help & Troubleshooting

Hi everyone, is there a convenient way to update the baseband/modem on the z3c?

Lolipop on xt1068 booting ! But no cell

Hi there,
I successfully installed Lolipop on the xt1068, however I haven't got any cell reception. I have the EU versio and converted it to the US international one. After this I did't have reception and I can't find any radio images...
I have all the firmwares but what are the radio images ? I tried flashing the two modem files from 4.4.4 but still no cell reception...

I dont agree with you. When it updates to lollipop we do it via the ota update which checks if you are on a xt1063/1064. Then it patches the existing baseband to work with lollipop.
So I think my problem is that in the us version I had the wrong baseband already. It should be able to be fixed by flashing a EU baseband. However we don't have them yet on the net...
I've done this many tines with the Galaxy S3/4 and HTC one...

XT1095 | is it possible to downgrade from Marshmallow to Lollipop

Hi,
Id like to downgrade to 5.1 from Android 6.0. I took the OTA update for my 1095 and things arent working as well; specifically my reception has changed and i can not use a data connection reliably from the same location at work after the update.
Is there a way to roll back? Or should i try to flash the old modem from 5.1? Any help would be appreciated.

Hello All
I have unlocked bootloader and rooted my P9, but have recentley seen an OTA come through to turn my current version to B160.
I understand that I need to flash a stock Rom in it's entirety (re-lock BL and lose root) before I can proceed with the OTA?
The issue I have now is that my current build number does not appear to be available anywhere as a stock rom. I am in the UK and with the 'Three' network.
If anyone can point me to the stock ROM for my build or can recommend another stock Rom to flash that will work without issues, I'd very much appreciate it? :good:
