If somebody has nvram image of dead Cube T8 Plus tablet or is willing to share his own, I would appreciate it. I managed to lost my nvram backup and my nvram got corrupted.
I promise to change IMEI, Wireless and BT MAC address and tablet serial number before connecting to the mobile network.
Thanks

Dear friends.... is someone able to send me, or load somewhere, a copy or your Ulefone Be Pro NVRAM.BIN....I'm not sure it can help but could be useful because flashing a ROM I selected "format all" and now I've lost the NVRAM hidden partition where the IMEI codes and other important stuffs reside :crying:
I've alredy tried any existing system to write back the IMEI codes; using engineering mode AT command the phone answer me "the command is not allowed in userbuild" ...I don't really know what it means, the phone is rooted.... using MTKDroidTools I cannot see anything in the IMEI area so I cannot restore/backup IMIEI's....tried with SN Write Station tool, nothing....Maui META 3G ver 6.1316.1, nothing.....IMEI&SN Writer, nothing....
At the end could be that they don't work because the NVRAM partition has been lost....but I'm not so expert.
My actual solution is: copy the NVRAM folder, fortunately I've made a backup before, under /data/... and it works.... but the phone MUST be rooted and every time I make a full wipe, I lose everything.... any suggestions?!?
I need exactly same NVDATA.IMG, but for Ulefone power 2 , anyone can share it with me please
I have IMEI, MAC ... but SIM cant be registered to network and nearly all sensors does not work ...
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
Hello,
I have a big trouble with my Lenovo K910 (dual sim), because wlan mac and bluetooth addresses are unavailable. Some of you would know how to restore tose addresses ? I don't have a backup of qcn file, because I bought phone without working bluetooth and wifi. I've tried QPST, but there are no position 447 (bluetooth) and 4678 (wlan). Someone would like to help me or send a copy of nvram partition for this phone ?
Hello, I am tying to update my IMEI & Wifi address in my Gionee A1 Plus phone based on MT6757P chipset. When connecting to MAUI Meta 8.15, after showing the NVRAM Database location, it says that database cannot be executed.
I also tried using SN Writer tool 2.15, it shows that META MAUI DB is not consistent. Out of curiosity, I checked the verion of the software using MAUI Meta & turns out that the SW version is same with the database file I am using.
I am confused. Kindly help me.
Hello there ;
Can you send me the nvram file of MT6757.

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.
