You cannot repair unkonw baseband with cert :-)

Sir please read carefully my previous posts you're the one who mentioned baseband if you see on the logs i posted Baseband is Ok I told you I'm trying to repair IMEI not Baseband my baseband is fine i just need to repair IMEI(Write Cert) on the G900V please read again our previous conversation so you can get back on track on what we are trying to resolve here. Thanks for the support

Use wipe fs and share report here if imei is 01

i got the sulotion for the N900V, N900p Cert Repair if i can get N910U Cert i will post the Cert file for the N900V and the steps by step how to do it it thank You

Don't worry bro i got it working i just used another tool because all my tries with ASB were unsucessful but i tried once with Z3X and it writed the cert sucessfully i think this box is trying to write the cert in a diferent partition

all is same
you cannot write cert on unknown baseband phone

write cert done :-)
no imei and write cert????!!!!!!


you use reset efs and then write cert !!!!

Wow bro you really never understanded, who said the phone had a unknown baseband, NOT me, you said that and i responded you that the baseband is ok i even showed you logs so please don't be saying that the phone had a unknown baseband just to cover that the software doesn't work. If you're really saying that it had unknown baseband and like that it i cannot write cert, how I did it in one try with Z3X. My problem was that even with the process finished still the phone had no IMEI I wiped EFS but when trying to write cert it never writes the IMEI in Cert it was still no IMEI. So please take a look at your software.

connect phone to usb and send user pass team viewer on sonork
