Please Help: No Signal Anymore - Nexus 5 Q&A, Help & Troubleshooting

I recently flashed paranoid android remix rom and I suddenly lost all of my signal and it will not come back. It keeps saying searching for signal. I looked in the settings and there is celluar strength. I tried flashing the radio and changing ROMs but it didn't help. I dont have access to a computer to flash the factory image. Any other ideas? I would appreciate any help! Thanks!

Try to flash stock factory images then.

Check and see if your imei is showing 0's. If it is your screwed unless you have an efs backup

Why would you post this here, go to Q&A or take a second to look around because you probably aren't the first person to have this problem...

Sober up and search around alittle

Your phone is most likely fine, you just don't have the patience to fix it yourself.

You're in the Verizon s3 forum, ask this question in the i9300 forum, the phones are completely different.

And you manually Odin to 4.1.2 with full firmware?? It's not possible to downgrade...Anyway, try to Odin again with PIT file and full factory firmware. Also make a backup of the IMEI folder before you do it. http://forum.xda-developers.com/showthread.php?t=1804117
If still not working you need to replace your SIM card(free from your provider) and call your provider to reprovision the card, just like when you first brought the phone.

D821 with USA band

Hi, i've got a strange thing , i bought an D821 in the netherlands and it's showing USB Band in the radioband section , shouldn't this be : EUROPEAN Band ?
I've got troubles with service dropping , that's why i asked
Thx for helping
:good:
I don't know what you mean USA band. How are you checking this?
All baseband software is interchangeable between the 2 models. It may just be the baseband you're using isn't good for you.

I'm in the states but I'm using stock rom unlocked and I just put in the correct apn and get lte, no custom software needed. Check to see if your carrier supports the lte bands on this phone.

You need to make sure that the bands are compatible. It sounds like they are not.

I went ahead and did that for you, no LTE compatibility unfortunately. No rom will enable it unfortunately since your carrier is incompatible.

Are you using a custom ROM or are you using stock?
If using a custom ROM, ask about this issue in the thread where you got the ROM from.
If you are on stock and you updated via OTA, the issue might be caused by something left behind from before the update, try booting to recovery and wipe only the cache partition, do not factory reset, then reboot and see what happens. If that doesn't help, try booting to recovery and factory reset the device.
