LG Nexus 5 (D820)

Here is a modified QCN that i made from a LG Nexus 4 ... Don't worry i have tested the back up with many LG Nexus4/5 with no problem ...
The QCN has been modified with Zer0 IMEI so you wont have to worry ...Connect the phone as DIAG mode and, just write your IMEI using EFS Pro ...
This is only if you lost data/service and only getting EDGE, Or a bad unlock method ...
**nothing should happen but again i'm not responsible for anything that happens to your phone**

So, you write this QCN file, and that will allow you to write your IMEI?
Thanks for providing the file but we're not too clear on how to use it.

The file you give has MEID and ESN numbers and IMEI (zero). When I read from my phone using EFS Pro, these number show 00..0 except my original IMEI. I tried to write your file - writing my original IMEI in the box and just choosing IMEI. Nothing happened. No 3G or LTE. I also chose all the three numbers leaving MEID and ESN as it is. Still nothing. What did I do wrong?
PS: I am using Qualcomm NV tools which is inside EFS Pro. I could manage to connect the phone in diag mode.

may be need to copy the nv file from good phone than writ it back with qpst..................to get 3g never tried but aim lookign for nv files all over but no luck

Shouldn't the thread title say SOMETHING about the purpose of the thread?

Also a banned subject!

I thought the imei was in a. File (dot) and cant be accessed? Since having a Chinese phone that had the imei in the writable memory and i wiped with a factory reset ive allways copied and kept away from the phone. Did try to get help on here but had thread closed like i was up to something illegal!

hey,
I googled so much but didn't get an answer
I simply didn't got a tutorial, how to install qcn files...
I have repaired my phone from a 0 emei, but now 4g does not work at all and 3g is also not that fine...
So I would be so pleased if anyone could send me a step by step tutorial or send a link for how I can write that file.
Sorry for my english...
Best Regards!

Question
hi! I've recently bought a Nexus 5 which was updated to lollipop, lost 3g/4g connection and rolled back to kitkat, the problem still persists.
I've tried 5.1.1, 6.0 and now on cm12, whenever i try to switch to 3g/4g, it automatically disconnects itself from the network. Tried several radios, APN is good, and 2g works great.
This file would help me to restore 3g/4g connection? My imei is shown, so i don't have the "0" imei issue.
i would need to put the phone in diag mode, then run the qualcomm nv tools from the efs pro, and then upload your file to my phone via NV Backup/Restore function?
Thanks!

I forgot to take a backup. I think qcn backup is getting wrong in the current version. so he needs me to backup the original modemst1, modemst2 and fsg partitions.

How you do this Wipe/Restore Persist?
Do you erase folder in TWRP or you make folder empty with code?
Do you have any clean QCN file to share with us? ( i dont need your imei)

My mi 8 crashed and broke the screen, I changed the display and the battery, after that I was without signal and without wi-fi.

I'm from Brazil and here is no assistance from Xiaomi
I have the imeis that comes in the product box. I just wanted to write you again, but I can not
Would you be very kind and send me this backup qcn?
Thank you very much.

Lost IMEI and got NVRAM Warning

Hello! I lost IMEI and got NVRAM Warning after flashing Redmi 9 with SP Flash Tool. I tried lots of programs to repair it like Maui Meta, SN Write Tool etc. But I can't get the drivers working properly. Are there any other ways to repair it? If there are, could you please help me to get it working? I feel like I'm already about to surrender...

If you didn't backup your IMEI before you lost it, probably you will never can recover both of imei.
But, you can recover one of them.
You need to write the IMEI to any (newer) device that allow imei writing. (Redmi Note 8 Pro can does it.)
And then, making the imei 1 as empty/null and into imei 2 you can write your new imei.
After it, you can backup the nvdata from that phone and restore it to your device.
So, you will have only imei 2. If you try to write imei 1 too, your device will get nvdata corrupted.
Good luck.

If you lost your imei, definitely you didn't make a firmware upgrade, but a format all.
Shas45558 said:

Yes, you can.
But you need a sim card from an operator that doesn't require the imei for using its service.
And obviously, you need your baseband intact.
If you try a sim card from an operator that requires imei for using its service, the sim card will not be registered.
If you want to restore the state of UNLOCKED BOOTLOADER, you need to follow this guide: https://forum.xda-developers.com/t/...omi-redmi-note-9-xiaomi-redmi-10x-4g.4220013/

I just found out that mi flash pro shows my IMEIs when I connect my phone in recovery mode. Could it be possibly happening because of the new firmware and I just need to flash into something different than global version or I'm wrong somewhere?

No. It will never write or recover your IMEI.

Accidently got the drivers working. Then i tried using maui meta and sn write tool to fix imei but i got errors. For example maui meta says "Write to target failed" and sn gives something like timeout error. Never felt that close...

Question Help with an unbricked Poco M3 Pro

Hello guys, after some struggle trying to unbrick my poco m3 pro, i faced a new probem, my IMEI has gone, as a noob that i am, i didn't made any kind of backup, i'm trying alot of ways, and still i didn't had any luck to re-write my IMEI (i still jave the numbem on the box of the phone) to the device, i'm using linux, almost everything that i found is to windows, does jave any kind of tool for linux, or i'll have to put windows on my laptop just for this porpouse?
there is anychance to use mtkdrive tool, the same used to bypass security for sp tools to do this ?
thanks for now

if your mobile services works, write imei is not necessary. and it's a dangerous operation. so if your devices now works fine, my suggestion is DON'T TOUCH ANYTHING
all my old phones that after modding lost originals imei worked without problems
a mobile sim could work also with all imei numbers=0

sadly my mobile service don't work, i keep zero signal, and when i try to get IMEI numbers on Settings > About device, it says unknown on both IMEis

ok
first try your sim into another device to be sure is not damaged
second search xiaomi redmi note 10 5g fastboot engineering rom and flash. this rom should repair some high problems like your.
if boot and all work fine, update to miui13. good luck

its only information and you can use Maui Meta in Meta mode if you enter edl/testpoint, for me the first time lost two imei only return The Second imei, but send to waranty and change the Phone.
of coursed use a Semi Profesional Tools.
