[SOLVED] No Signal after update with "Wipe All Data"

People
Can someone help me?
It's about a month that i have this issue...
After a flash of Kitkat using the GNQD Tools v2.1.0.1 with the option "Wipe All Data" i've lost the NV RF settings.
WIthout a previous backup i'm now stuck...
Please anyone with a working Gionee E7 32 Gb make a backup of this items and share?
=========================================================================
Solved thanks to user jdgomez001
Read the thread, the qcn file is posted twice

Please... anyone...
HELP ME..... :,-(

I have the same problem. After upgrade firmware my E7 to 4.4.2 (GNQD flasher with option "Wipe all"), i lost my NV settings (include IMEI, MEID, ENS ). If you find backup QCN from our phone (E7, BLU pure XL, etc), please, share it to me...
And if i find this backup, i'll help to you.

HI
I got a BLU Pure XL qcn and now i have GSM, but no 3G/WCDMA.
We need the original Gionee E7 qcn to get all working
If you want download E7.QCN.OK_IMEI-0.qcn the BLU qcn if you want to get GSM/EDGE working for now...
As i said before: "Wipe full data" really wipes...

Ok.
What method you use to restore the QCN backup? QPST QFIL, QPST Software download, EFS professional, or maybe, something other?

QPST 2.7.378
Software Download - > Restore

Thank you! I used QPST newer version (2.7 rel.422), and nothing worked. Try this version...

Try with this version.
In Software Download - Restore when the software is trying to "reset device", reboot it from adb or from the device it self.
Please feedback, my 3G is working now... I believe there was a problem with the SIM card i was using before...
This might be the solution all together.....
1 - Restore the qcn
2 - Restore your IMEI
it should be fine!!
I tested again adn now i got 2G and 3G...
Man, how i'm happy!!!!!
After a month of this finally my 'new' phone is working ok

Congratulation!
What about me - i have a bootloop after restore on 4.2.2 firmware, and "unknown" IMEI, network and other on 4.4.2 firmware... I can restore IMEI, but i have not gsm/umts network signal.
If you get a working phone - can you make a backup memory of your phone (without userdata, system and other your private files) with "Partitions Backup&Restore" (from market) ?
I think my problem - the consequences of my "experiments" with memory...

Try this:
1 - Remove the SIM from the phone
2 - Install kitKat with GNQC 2.1.0.1 using Wipe All Data
3 - Load QCN file and reboot [if your using the first file i shared, delete it and download the new one]
4 - Restore your IMEI using QPST and reboot [i could be necessary repeat this step || the IMEI usually don't stay at the 1st and 2nd attemps]
5 - When on boot you have your IMEI back, insert the SIM card
Sorry bout the file, the first one i shared is from a Blu Pure XL. To work properly on a Gionee its necessary to flash the Blu Modem also...
If you are flashing the phone with GNQC tools, you can check that there's a QCN file on the Firmware folder.
If you load first "Working-QCN-copia.qcn", dont reboot and load next the "WBW8901GI_0301.qcn", now reboot you will fix the boot loop.
The file "E7-GSM.OK_WCDMA.NOK_IMEI-0.qcn" is the BLU file modded to Gionee, so if you load this one you dont need to load anymore qcn files.
Keep feedback me.. We'll solve this

My feedback.
1. Ok. Removed SIM card.
2. There are installed KK 4.4.2 with GNQC 2.1.0.1 with option "Wipe all data"
3. I'm load your last QCN file and reboot.
4. After reboot I have next situation:
- I can't restore my IMEI, because QPST doesn't see my phone. In "Device manager" on PC there is same COM-ports that before load QCN file, but in QPST same COM-port is not active ("No phone"). What is the reason - i don't know.
Can you make a backup NV parameters with EFS professional? You can delete your IMEI in string 550...

I might share that with you, but i just dont see how that will help you....
You still need to set your IMEI on the device...
Making a backup file now... this might take a few minutes..
Meanwhile, have you tried to set your imei with EFS Prof? Has i said before, it might take a few times for the IMEI to stick.
You can also try to set your IMEI with DFS CDMA Tool, that also works!
Please, don't stress up! It wont help! Take a deep and long breath and try to set your IMEI while i backup the NV Items with EFS

Thank you very much!
I fixed it!
I restored my old files modem1st and modem st2. After i'm restored QCN backup (with the help of your file). And, before reboot, was loaded QCN file from firmware (WBW8901GI_0301).
I'm used QPST 2.7 build 402. Only this version, 402, has helped me!
I'm happy!!! Yeeeah!!! Thank you for help!!!

No network or IMEI after Nandroid restore

I tried out Marshmallow but didn't like it so used a nandroid backup to completely restore the phone.
After a few errors trying to restore (think it was a 255 error?) in recovery it finally worked however now I have no service, and the IMEI just says 0.
Can this be fixed or have I now got a small tablet?
Note: I am not trying to change my IMEI which I know is illegal, just trying to get back my one.

restore a 6.0 twrp backup..changing IMEI in a snapdragon device is a pain in the ass. MTK devices are easy.

I don't have any TWRP backups from marshmallow, just one from lollipop. I read that QPST is the tool that sorts this however Windows cannot find the correct drivers (despite having Motorola Device Manager installed) for my device so I cannot input a port into the software to find the phone.

I read somewhere that flashing stock firmware solves the problem, you should try that

Flashed the file you said but still IMEI is 0.
What now?

If no one else has any other software ideas then two things come to mind:
1. If you have the box that the Moto X Play came in then the IMEI is on the outside of the box. The information on how to restore it is on the Internet. Just google it. Not going to discuss it due to legality issues.
2. Return the phone to warranty depot for repairs if possible. Not sure on your circumstances.

Need EFS Backup of WORKING Nexus 6P

Google will not admit this but there were major security flaws in factory images before jan,2017.
Read for yourself below article.
Link: https://www.google.com/amp/www.tech...d-nexus-6-patch-fixes-modem-vulnerability.htm
They patched it in Jan. But effected users like us(who got effected on 2016) got proper fu***.
The result : NO SERVICE but detects sim card.
Kindly.....Plz....plz...plz....make a copy of your efs and provide it in this thread. Please also mention what factory image/build number u are using.

No one will give you his EFS backup because its unique for each phone..so you cant use someone else EFS on your phone...

Really?? Thats a big news for me its no problem do i know him or not.. How can you use someone else EFS/IMEI.. it would be 2 phones with same IMEI number..maybe it will work, but its like you use someone else ID card and present it like its yours..

Hey,
When the IMEI is corrupted on the software side, it still shows up using:
fastboot getvar all
So the IMEI is somehow corrupted on the EFS partition. How, I don't know. Seems like the EFS acts like a bridge between hardware/software. Of course, I could be wrong...
Some have tried but didn't succeed. Now, it's not the first time I see someone using another EFS backup and getting his IMEI back. I don't know why it would get "their"" original IMEI instead of the one included in the EFS backup either. But i guess they must all lie saying it fixed their device.
Cheers...

I have restored EFS using a backup from someone else's device EFS. It did not change my original imei.

Down do it. The efs is device dependent. It will contain things like your imei. So even if restored on another device it will end up causing issues due to the same imei on different devices. It can also make it so things like WiFi don't work

Okay thank you, I had no clue about efs so I'll take your word on it.

Guys can anyone share efs so that I can restore and save my phone..I Have no signal ispitevof detection sim card...it shows no service.. But when I use jio it shows full signal..kindly help..

I had similar problem with my OnePlus X. Apparently I was saving and restoring my efs partion with every twrp backup which eventually caused it to become currupt. Thought my phone was toast until a friend on telegram suggested deleting modem1 and modem2 files with adb commands. Sounded more destructive then good but it actually worked sim was reading again and got full use of my phone. It's good to make backup of efs but only once. Not sure if this is the fix for every phone but works with OnePlus and Xiaomi.
How to Fix EFS from Bootloader Mode using Fastboot commands
Setup ADB and Fastboot on your PC.
Enable Developer options & USB debugging on your Android device.
Connect your device to the PC and open a command window on the PC.
Issue the following commands one by one:
adb reboot bootloader
fastboot erase modemst1
fastboot erase modemst2
fastboot reboot
Got my information from here

A2017G @B08 -> no network connection

Hi!
Really need your help
I flashed my phone and sold it.
Now customer claimed no network connection and sent it back.
Today I checked the phone and saw, that no IMEI were present.
I restored the IMEI, but there is no network connection.
I flashed the OEM ZTE image and have no clue what else could help.
Any idea?

Is this maybe MODEM related?

I would try reflashing the modem, making sure you're using the latest twrp 3.1.1 and that system is mounted before flashing.

Sorry. Can't help you there. I have no experience with restoring IMEIs and resulting issues.

i use an A2017G stock
https://www.pic-upload.de/view-34346603/Screenshot_2017-11-22-11-27-05.jpg.html

I sometimes get problems just after flashing, and GSM/Wifi 5Ghz take up to 5 minutes to initialize. Deactivating and reactivating the sim card helps. Did u try that?
- Else, I'd get a 7.1.1 factory image and start over, that baseband is *exactly* the same as mine and I only have that "5-minutes-without-wifi-and-network" bug.
- Try looking for wifi just after booting the phone : if you only see 2.4Ghz networks and no 5Ghz network, just turn the sim car off and on, and it's ok, just that bug.

reflash a full stock firmware, if you have imei, you must have then, then if you want, do the process again to get twrp

Hi Folks,
i've done some reading and my problem is a broken EFS sector due to TWRP recovery.
Even after manual IMEI restore, the EFS is broken and causes the no service issue:
https://forum.xda-developers.com/axon-7/how-to/investigation-recovering-efs-twrp-t3522171
Only option is to get a EFS copy from another device, push it on my one and change the IMEI to my own manually.

If efs was ’restored’ using the signed twrp used for unlocking then there is no fix for that.
