Good evening.
The problem with my device is that after flashing a numeral of roms in panic after a failed power up, the system does not detect any kind of network. I presume this is fault of the radio since in the phone info menu, where the state of the radios is displayed, always marks them as off and they cannot be turn on.
And while previously my IMEI and Baseband had been lost at, I've successfully restored them, although with both SIM cards having the same number. Even after that the networks don't work. The CIT/QC test of the SIM card does in fact read it as present inside it's slot, as well.
Another couple of symptoms are that, first after the disastrous event of a flashing, none of the sensors were reported as working in CIT/QC, a problem I solved by once again flashing the persist.img file.
The second consequence is that neither camera would work, just displaying the message "Can't connect to camera"' (Or something alike) after a few seconds. This I solved after flashing a Kate rom.
Notes:
Measurement of the phone returns 152 Milimeters.
Phones Internal Storage is marked as only 10 gigabytes, having only 2 gigabytes of RAM.
Do you try with latest official miui rom? Flash it with MiFlash in fastboot mode.
Select:
Clean all and lock
You can try to change your imei to other and if doesnt work try again with the original.
I dont know other way.

Hello. Yesterday, after accidentally doing a data wipe in CWM Recovery, the phone stopped asking for PIN and registering on the cell network. Everything else works fine (incl. WiFi and Bluetooth). The phone says it is out of range and won't even make emergency calls.
When going to the "About Phone" menu and then to the Status page, both IMEI and IMEISV come up as "unknown", the network is "unknown" and the signal level is zero. Does this mean that /efs somehow got corrupted? I can still see files in it though and nv_data.bin / nv_data.md5 are present.
This behaviour is with stock-based firmware. CM7, though, behaved differently: it asked for PIN but could not unlock the card (it showed a "unlocking sim card" message which stuck for a while before dissapearing without unlocking the card).
I have both a .tar.gz and an .img backups of /efs. How can I restore the second one? I tried this: http://forum.xda-developers.com/showthread.php?t=882039 but it failed, leaving an unbootable phone (which I salvaged by flasing a firmware via odin).
Also, for some reason, Root Explorer won't mount /efs as R/W.
In case I have to send it to Samsung, do you think that reverting to stock and resetting the custom dl counter with jig will fool them?

Doesn't like booting from recovery on recent radio. Try full power off and on.

I just got this phone brand new a couple of days ago(P769 model). Everything seems to be working fine, except that sometimes when I try to send a text over wifi calling, I get an error message that says "No usim card". So far resetting the phone each time I get the message has fixed the problem and allowed me to text, but it seems like the type of thing that will only get worse and more frequent as time goes by on top of it being mildly annoying having to reset my phone every time this happens. Any ideas on how to fix? I tried swapping out my old sim card for a new one, but that didn't help.
Never heard about such error. USIM is simpy a SIM card supporting UMTS with no software emulation. Try emergency firmware recovery from LG PC Suite. It will wipe all your data so make a backup if needed.

Do I need to download a specific version of LG PC Suite for the 769. I couldn't find a link to it on LG's website. I tried downloading the version they had linked to the 765, but my phone would never connect with it. It would say it was connecting for about 30 seconds, and then it would say it failed.
You can use this method: http://forum.xda-developers.com/showthread.php?t=2085344&highlight=lgmobile+support+tool
Or just download LGMobile Support Tool (p. 3 in above post), install msxml.msi than B2CAppSetup.exe, run it and connect the phone, upgrade recovery from options. I was recovering my phone this way after failed rooting of the device. BTW PC Suite should work with all p76x.
So, I've had a lot of problems with my phone lately, including a semi-brick for a while. After all this mess, I had to do re-partition, fix WiFi and stuff like that.
Recently, my only problem was no service after inserting SIM card in CM12 (basic stock ROM using Nubia Tools, repartition using official 2.03 ROM from NeedRom & finally CM12 for Nubia Z7 Mini from NeedRom). SIM card was fine but there was no service, I've tried re-inserting it, I've tried different SIM cards etc.
The issue went like this: phone crashed and "turned off" after inserting SIM card. It wasn't really off - Windows was detecting it as several storage disks (?), and it was heating up after a while. Long press of a Power Button made it reboot to system and it was running fine, but only without SIM card. SIM card made it freeze, heat up and the issue was happening all over again.
Currently, I've tried to fix that by flashing latest Resurrection Remix. Now, phone is stuck at "emergency calls only" - it tries to find service but without any luck. I've read that it might be an issue with bootloader - that there is some script that is trying to run, making it unable for the SIM card to grab service. The phone is really heating up with SIM card in it, but it definitely detects it and it tries to find service without any luck.
Maybe flashing only modem would do? But I can't find it anywhere.
What can I do to fix it? IMEI numbers are fine, on their right place.
I have a Jiayu S2 double-SIM phone, running the most up to date official ROM (4.4.2).
This ROM had a couple of bugs (no GPS and no notifications to external devices such as smartwatches), so I wanted to check other available ROMs. Using the Flash Tool I have tried a couple of the ROMs in the needrom site (https://www.needrom.com/category/jiayu/s2-jiayu/). In particular, a couple of versions of the official ROM, another ROM known as Salamander, and an unofficial port of Cyanogenmod 12 (in which the camera was not working).
The issue is that, for some reason, at some point my phone has stopped getting phone signal. The SIMs ask for the PIN on startup, but there is no signal. I have reverted to the original ROM; plus done a factory reset, and I could still not get signal.
The APNs for both SIMs are fine. Then I have realised that the IMEI was empty. Luckily I had it written down, so I have installed Xposed and the Device IMEI Changer, with which I have been able to restore the IMEI. Now I can see the IMEI on the Settings - IMEI information, as well as with *#06#.
But still, now with the original ROM, and with the IMEI restored, I still cannot get phone signal. I have tried setting the phone to flight mode, restarting, selecting manually the network... When trying to manually select the network I can see several networks, but the phone will simply not connect to the one it should.
Any idea on why could it be that I cannot get phone signal? Thanks.
After trying everything, including restoring the IMEI with Xposed, I have finally managed to restore cell service by restoring the IMEI with this tool: https://play.google.com/store/apps/details?id=com.cryptotel.chamelephon
I have had an unlocked VS985 for three years now overseas and its been flawless so far. It all started when suddenly one day the SIM failed to be recognized. I put the SIM in an another phone and it works fine. No other SIM card gets recognized on the device. These are a summary of things I've tried so far:
1) I initially thought flashing another ROM would fix it, and I tried like 3-4 ROMS available in XDA (thanks to all the devs!!). Nothing helped. The SIM continued to be unrecognized in all the ROMS. I then flashed back the stock ROM by the TOT method.
2) I then suspected it could be something with the phone radio and started investigating in that direction. I tried enabling all the bands through the shortcut app and that too did not fix it.
3) I found the hidden menus to attempt turning on/off the radio but found that I was unable to enter what's called as "Phone info" hidden menu (picture attached) that contains this radio on/off option. Although it didn't let me enter I noticed that the phone IMEI in that menu was missing the last digit. The IMEI in the Setttings -> about phone (or below the battery) shows an IMEI with the same digits but with one extra number at the end. I suspected that somehow this IMEI mismatch of the last digit IMEI was the reason the phone is blocked for all cellular connections.
4) I then tried fixing the IMEI with the Qualcomm QPST method but unfortunately unable to enable the DIAG USB ports. I tried that with adb commands with terminal emulator and all the commands are accepted without an error. But when I connect the phone with debugging the appropriate COM ports don't show up on the QPST configuration. I also tried that with the phone hidden menu (##7764726985) but the "Port check" option that must show up is just not there.
I am stuck now. I am not sure what exactly has happened and if my diagnosis on the IMEI is valid. A phone service center tells that the SIM slot is good and this is a software problem. Can someone please help me fix this? It could be a simple fix to access the DIAG USB port or a bigger fix to the whole problem. I just don't understand how the IMEI could have randomly changed when it was fine for all the 3 years thus far. It has been a harrowing 2 weeks trying to find a solution and I'm tired. Please HALPPPP!
EDIT: I was able to get into the debugging mode and was able re-write the correct IMEI. I restarted the phone and still its the same as in the first picture, missing the last digit. May be as a consequence, the phone is unable to recognize SIM or letting me access this menu
I received the SIM card unrecognizable alert, with my original G3. I took it into a VZW store and they told me it was a hardware failure. They replaced the phone on an insurance claim. Never had the issue again. I don't have any experience IMEI issue.
