warning can be fixed with the guide in first post.


But the IMEI will always be overwritten when you flash a new rom since its stored in there !!!!!!!!!!!! No way around it, everytime you flash a new rom or wipe you have to do this

hi, not sure if the downloaded file from your download link for the imei generator is correct. I got 3 subfolder under the main IMEI folder. is that right? So, when i run cmd in IMEI forlder, it says imei.exe is not recognise

This would be a great guide if key pieces of information weren't missing...I recently downloaded the IMEI.zip file, extracted and got 3 subfolders:


01Android_Gadget_CDC-driver


02MauiMETA_3G_exe_v6.1316.1.upload.ASHAKAAS.INDONESIA RAYA


03DB


None of these folders have imei.exe in them, and opening command prompt yields nothing because imei.exe is not recognized. I am attempting method one on Lenovo A850. Baseband was wiped when flashing a rom, now IMEI is invalid and baseband is not known, and SIM is not being detected. Please help by being slightly more specific regarding the use of these files in the download. Thank you!
