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

asslam o alaikum, and hello brothers and sisters here, i am a new user here. i need help. i have a lenovo A3000-H ideatab. i buy it from china. i do the firmware upgrade from http://forum.xda-developers.com/showthread.php?t=2441135. but the bad thing that happened is, i format and then i download. the problem is that now invalid IMEI..that i fixed it by Engineering coding mode...
'"code in Engineering mode:-"'
Just enter this code in dialler:- *#7465625# or * # * # 3646633 # * # *
Now Tap on Call pad or connectivity option or you have to slide the screen.
Just Look for CDS information (Common data service information) option.
You will see Radio information there and after tapping on it.
If you have dual SIM ANDROID then you will see TWO option select any one on which you want to write IMEI with.
Now you will have to put your IMEI no in this manner :- “AT +EGMR=1,7,"IMEI_1” and “AT +EGMR=1,10,"IMEI_2” (replace IMEI_1 and IMEI_2 with your IMEI no) and tap on send command button.
for Example :- “AT =EGMR=1,7”9100XXXXXXXXXXXX”"''
( also it will be helpfull for others) please do not misuse it. its just help to solve your problem
the other problem that i fixed it is nvram error= xo1 for wifi mac adress that was formated by me... i just took a data\
nvram\APCFG\APRDEB\wifi from it i copied wifi name document from my friend tab that is same to me and paste it into my tab data\nvram\APCFG\APRDEB\wifi. my tab wifi doc replaced . the NVRAM ERROR=XO1 from wifi gone...
the thing that i need is that when i restore to default after some days to check there were no IMEI . it says invalid IMEI and also the same NVRAMERROR. that i fixed it again by the above method that i explained. then i do firmware upgrade but this time i did not select the format option, i just download.but after finishing firmware upgrade, when i turn on my tab it says INVALID IMEI AND SAME WIFI problem NVRAM ERROR. BUT I WANT THAT is there any method from which if i ever do firmware upgrade or restore default it should be fixed and it will not say INALID IMEI AND NVRAM ERROR. I JUST HATE IT. PLEASE IF ANY ONE HAVE ANY IDEA IT WILL BE A LOT HELP ...
""'''SPECIALLY THIS QUESTION IS FOR AZAM426"""
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 ...
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 ?
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 ^^

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!
