Nexus 5 Emergency Calls Only (EFS Maybe)

Hey Guys,

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.

Does it show your IMEI?

If it shows a zero or multiple zeroes it might be a corrupt IMEI.

Okey then its not, IMEI is still valid, Phones IMEI is still the same, I have tested the IMEI aswell with my service provider and a paid for service on the net that indicates all is in order still.

Sounds like an issue with the SIM card holder and/or connection of it to your motherboard. I know rma is difficult for you but that's probably your best option.

It would make some sense somewhat as recently after i updated i had dropped the phone from a small height, and that option has been playing on my mind ever since. What i cannot get is that the device still picks up a sim card when its inserted into the phone or will this still happen regardless? Iv practically ruled out everything, im getting a replacement phone tomorrow and Ill them log a call to google to get things moving with a RMA.

Another thread has suggested re-flashing the cache.img from the stock file, will this wipe everything or do you think it would be worth a try ?

It's worth a try to flash the cache. It will not wipe your device or anything.
