Hi,
I have made a mistake trying to change a rom for my device (Lenovo s820).
I thought my phone was gone, but step by step I was able to bring it back to life.
Now I have a working rom and I set back the IMEI's, but I still have "no service".
After reading a lot, I understand that I need to recover my "NVRAM" and to do so, I need for somebody to send my a file called "NVRAM.IMG" which applies to my device.
I can't find this file anywhere on the net.
Can somebody please send me?
Thanks in advance

does nvram.img file needed with secro-sign.img to retain lost sr.no and imei no mac
does nvram.img file needed alongwith secro-sign.img file to retain the lost imei no sr.no mac address and bluetooth settings in meditek 6737m device name moto c plus.
Long story short, I have 2 of the Lenovo Vibe Z K910 dual sims phones. One got bricked while doing a update to a custom ROM. I was able to recover, but SIM1 slot wasn't working correctly. It would recognize the SIM card but seconds after booting it would go into "No service" state. So, using the QPST Software Download tool I did a backup of the working phones QCN info & restored it to the phone with the issue. Both SIMs worked!! But the IMEI for SIM1 slot & the mac addresses for WLAN & bluetooth are the same on both phones. I was able to use RF NV Manager to edit the QCN file with the correct IMEI info save it & restore to the phone. Now I just have DUP mac address for WLAN & bluetooth. I can do a "Restore QCN" via the Lenovo recovery menu, that gets the correct MACs but then the SIM1 slot doesn't work right again. I've looked through the QCN file with RF NV Manager to try to find it but must be missing it. Anyone know where in the QCN file I can edit the MACs? Or any other way to correct the MACs.
Thanks in advance
Hey everyone. I had a problem on my KOLINA k100 (mtk 6592) , so I installed another rom, this one:
h tt p: / / www .needrom. com / download / 100- v6 / (please remove the spaces)
I had some trouble with other roms before that, and, in the proccess, I lost my phone IMEI. I tried everything to put it back, like engineer mode (didn't work for me, i fixed the imei and it didn't say anything, like if it has succeeded or failed), MTK Droid tools (it says in the program that it worked, but i reboot the phone and it is the same when i do *#06#, until i saw a program that seemed to work for a lot of people. Which is IMEI&SN Writer. But, after attaching the database files, and the program asked me to turn the phone on, but, then, it says that it has failed!
What can i do? it has no removable SD card and not removable battery... thank you
You will have to send it in. If you don't have a backup there is nothing anyone here will do for you as messing with the imei in any way is banned as it is illegal in many places.
im trying since few weeks to root or just wright that f***** numbers in my system, i flashed new software and new bootloader but cant register my umidigi f1 play, nothing works i tried nearly every manual/way ive found on the internet. it would be nice if someone spend some hours and do this with teamviewer for me or just create a system image with all my imeis, meid and android seal ... sn write tool always fail, flash twrp or adb debug didnt worked. maybe its the phone or im just not intelligent enough :ß pictures are at my profile ^^
@P41Nkiller
On each Android phone exists the EFS partition where all your important data like the IMEI number, MAC address of all the wireless devices, important files from the internet and product code, MEID, and ESN, registered phone number, etc. are stored.
Flashing a new ROM shouldn't have touched EFS partition.
I am using a Japanese Valiant S23 Ultra (SCG20).
I made full use of alliance shield, etc. to activate Diag mode and made the connection with QPST.
QPST recognized it correctly, but when I connected EFS Explorer,
I got the error in the screenshot and could not get the contents of the NV.
Are you guys able to connect EFS Explorer? If so, what version is it?
Could it be that the QPST/EFS-software does not support the 8Gen2-chipset ?
I have not yet succeeded in reading EFS with EFS Explorer, does anyone have a solution?
The Japanese carrier version of Galaxy has a tradition that the docomo version can read EFS and the KDDI version cannot.
I believe there must be some solution to this problem as it is the same HW and the only difference is the ROM.
As you can see in the screenshot, the ESN is displayed but the Phone is unknonw.
If you have any information at all, please let me know!
