Hi All,
I have an xt1763 that I am trying to fix;
- it has NVRAM error in the wifi list when you go through the wizard of the factory reset.
- it has imei of NULL for both sim cards.
I've downloaded the nvram from the device and it is pretty much all 000000000, so clearly its been wiped or corrupted.
Can anyone download their nvram for me and upload it here so i can (presumably) flash it with SPFlashTool to get the imei etc working again on this xt1763. Or provide me with any advice on how to resolve this without a nvram backup? I don't believe there is a way.
Thanks,
Scott
Sorted.

Hello everyone.
Got stock 910C with 5.0.1, today made root and twrp. backed up EFS with terminal emulator (got efs.img) on my sdcard.
Also made EFS backup with twrp.
Flashed custom 5.0.1 rom, right on welcome screen - lots of FCs. Wipes didnt help.
Returned back to backup of stock rom but now EFS got erased. no IMEI and cellular network.
Tried restoring with terminal and twrp - no luck
Can someone advise?
Try to make a software repair with Kies and report back
Dont forget, EFS doesnt contain any IMEI certs or CAL data, so if u clear EFS partition IMEI willl be the same, only SerialNumber will be wiped

can u clarify please. how can be serial number be wiped?
EFS partition -> SerialNo, Bluetooth, WiFi and password + settings
IMEI certs -> SIM LOCK, Imei number. CAL data
As u can see EFS erasing will never destroy imei number

then why did i lose baseband?
When you tried to backup EFS or root you lost MD5 signature of IMEI parititon. Now its gone. In some cases it can be undone by flashing to STOCK firmware.
Please check the screenshot for correct location of EFS partition and M9K partitions
i did restore my EFS by reinstalling stock 5.0.1 with odin.
Hi guys
Does anyone have a TWRP A2017G backup their willing to share?
I've lost IMEI and MEID and am trying to recover
Seconded. I seem to be in the same situation. Don't know if a TWRP backup will help, but I've been unable to connect to the cellular network after restoring a full TWRP backup which I suppose I shouldnt've restored. Re-entering my IMEI via a TWRP module didn't help as well. Neither does the adb shell dd command that formats the EFS partition found in another thread... Restoring EFS I backed up a while ago didn't help me as well.
Thanks in advance.
I have tried going back to stock boot/recovery backups, flashing every single A2017G update and even tried Tenfar's tool to restore the removed backups in his thread. Cannot seem to fix
Only had this phone for 3 days and it's now useless.

Do you have a backup you could share?
As far as I know, the EFS bit is unique to each device. It contains your IMEI code, for example, which is unique for each device.... I can give you mine, but I'm not sure if that will help you.
I'll probably make a new thread asking for some help because I've tried about everything and I can't fix this mess on my own... I hope I won't have to send it back, no way of knowing they'll believe me
I've been doing some googling and perhaps we need a modem.bin file from a A2017G?
this is really not looking good
Hi! I have a hlte/SM-N9005 with LineageOS.
Today I tried to turn on encryption, but then I was stuck in a boot loop. I did a full wipe in TWRP and restored everything from the backup I made before (including the modem partition).
My phone boots again (without encryption), but isn't able to detect any SIM card suddenly. Not sure if something went wrong with the restored modem backup?
I tried downloading a Swiss firmware from this link, extracted it, and flashed modem.bin and NON-HLOS.bin via Heimdall - this didn't help either, though. I'm kind of out of ideas now... Any idea what's going wrong?
IMEI correct ??
Phone Status > Status > IMEI information says "IMEI: unknown" :-/ I'm guessing this is supposed to be there, even without a SIM?
Restore your backed up EFS folder .
Restoring the EFS folder from the TWRP backup is what got me into this mess in the first place. There's probably supposed to be a /efs/.nv_data.bin in the backup, but there isn't for whatever reason. I don't have older backups anymore either.
Hi there,
a friend gives me his Samsung S4 GT-I9505 with the Problem of no IMEI and no Sim-Card detected.
I tryed a few things like:
- EFS-Backup and restore
- Wipe everything
- New original Samsung Firmware
- New Custom Firmware
- newest Modem installed (the last in the list) (is it for Germany?)
- Now I installed Lineage, Open Gapps and Supersu, but nothing changes.
Is there a way to make a own file for the Imei or something to flash?
I hope you can help me.
sorry for my english... =(
Sorry, but all your attempts to restore the IMEI have been a waste of your time, including restoring the EFS partition. The IMEI and nv_data files are no longer stored in the EFS partition. They have their own hidden partitions that cannot be backed up with TWRP.
The only legal way to restore the IMEI is to take the device to the service center.
There has been problem with my radio/modem. I have tried everything but nothing works. I've tried flashing OOS modem files, going back to stock etc. I found one solution to restore my efs backup. But unfortunately, i dont have efs backup. Can anyone help me by sharing their modemst1.bin and modemst2.bin files ? It would probably solve the problem.
