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

How do you apply it, I have the same problem.
The bat file is not working, it says cannot find adb.exe.
I put the adb.exe at system32 folder along with the dll files and still bat is not working

Hey everyone, I seem to have a problem that's really irritating me. I used .net reflector to edit some dll's in an app in an attempt to mod it. Well, when I go to compile the apk (using option 12) I get an error. I don't know how to fix this error, but it seems like it's due to a missing file maybe? I've already redownloaded it twice and still get the same error. Any help would be greatly appreicated.
I have a youtube video, but apparently it says I can't post outside links? -_-
remove the spaces and please watch the video youtube . com / watch?v=4uoE3n0mEfg
Hey guys,
I've found that my mac address in this file "wcnss_mac_addr" located at "/sys/devices/soc.0/a000000.qcom,wcnss-wlan" is 00:00:00:00:00,
and when i change it and confirm that was really changed i restart my device and check again this file and it's 0's again...
can someone explain to me why this is happening?
Obviously that's why my mac address is shown like 02:00:00:00:00:00 and cant turn on WIFI.
Any developer as a sugestion?
ps: my device is a Redmi Note 3 Pro SD.
Regards
Guys I have a whatsapp backup of all my chats from my old mobile phone with my old number which I don't have anymore.
I do have access to the google drive folder though and can see my backup floating around the web.. I was researching like mad and stumbled upon the Whatsapp GD Extractor from thsis forum.
https://forum.xda-developers.com/android/apps-games/tool-whatsapp-google-drive-extractor-t3483633
Whenever I try running it on my windows computer through the cmd.exe while having python (the newest version) installed, I always get the following error message:
Code:
Traceback (most recent call last):
File "WhatsAppGDExtract.py", line 3, in <module>
from configparser import ConfigParser
ImportError: No module named configparser
I don't know what to do, can someone from this forum help me?
facing a similar problem
Hi Friends, I know this is an old thread but well, I need help with a similar problem.
I am getting stuck at the point where i try to -sync and I get the following error
C:\Users\Ivan\Desktop\gd ext\WhatsApp-GD-Extractor-master>WhatsAppGDExtract.py -sync
Error=BadAuthentication
Is there a way around this??
Hi,
I recently rooted this device for purpose of changing MAC address and removing the "POCOPHONEF1-" prefix in device name. I managed to change the MAC but I can't seem to find a solution for other problem. I tried editing build.prop, it didn't work.. I also installed root essentials and edited "Device Hostname" (which shows the exact thing that I want to change) it would then automatically reboot, but when I check back in root essentials, the Device Hostname is reverted to the default. Changing "Device Name" in Settings->About Phone still doesn't remove the prefix. Any suggestions?

Yes, I tried both of them. net.devicename doesn't do anything for me. As for the second one, it only changes the name after the hypen (POCOPHONEF1-devicename) . What I want to get rid of is the POCOPHONEF1 before the hypen.
Hi. Any solution found for this? I also want to do same thing with my Xiaomi phone.
EDIT:
LOL. I forgot I already resolved this in the past. U can use the following apk for that: https://play.google.com/store/apps/details?id=com.bigos.hostnamechanger
Works with my phone, MIUI 11.
