Iv been undergoing a very strange problem, I flashed manually the 4.4.3 update to my Nexus 5, the phone worked fine for about 2 days after the flash and then random-ally one morning decided to display "Emergency Calls Only', I can scan for mobile networks just fine but it will fail to register on any network, here is some debugging iv been doing:
- Select automatic registration, reboot
- Switch off, remove sim, insert, boot
- Flashed all modems available
- Tried registering on different nework modes (3G, LTE, 2G)
- Factory restore to 4.4.2
Corrupted EFS rulled out.
The same sim works just fine in other devices and I have ensured that the sim card pins are clean and fine. I cannot find a article related to this issue and what I have been reading is that it could be related to a corrupted EFS, what i dont understand is that does the EFS corrupt the IMEI number or is their anyway to confirm it is a corrupted IMEI number ? If so is their anyway to recover the EFS and just inject my IMEI number into the file and flash back ? Would the Nexus 5 PIT file help ? Or in the end would a google RMA device be a better choice ?
The RMA is difficult for me due to the fact that im in a unsopported county so would have to post it back, but i obviously need a phone so need to sort this out.
