were you able to settle by writing nv date?
because I read three logs where you have the damaged security and a log of the program where you wrote the patch cert correctly

frosted · 08-14-2018, 12:47

the cert write is never successful

patch cert successful

write NV successful

but write cert never done

did erase EFS already before write EFS and Cert

baseband is not unknown

imei is gone because i did factory data reset on menu

frosted · 08-14-2018, 12:48

what i meant is baseband status is good...

if you do the patch cert it is normal that doing the factory reset remains unregistered on the network, strange that does not make you write the cert in conclusion if you patch cert the network remains instead writing the cert not z3x does not write it, but writing the patch Does the network work without making a factory reset of the phone?

after writing NV successfull IMEI still 350000006 and my serial no is gone

what did you write with the patch?
in practice, that you intend to belong to you
but if you do the repair imei and the patch cert without doing the factory reset the imei remains at 350000000000006

frosted · 08-14-2018, 16:03

i don't understand what are you trying to say

the patch is just i'm trying to do it to see if there is going to be the same error in procedure or not

You wrote that after writing the nv data successfully the imei remains at 35000000006, and your serial number is gone, I have only asked you when you write the new imei and make the patch cert if you imei you still have 3500000006 or remains the code imei you wrote and the network works, it is normal that the serial number using another nv date does not remain the original

frosted · 08-14-2018, 17:10

1. it was unlocked using root method (before imei is gone)
2. after factory data reset the device get locked again and the imei is changing to 350000000000006.
3. i'm don't have original cert backup, nv backup because i'm not the one who unlock it at the first time

so what i was trying to do now, is to recover imei, after recover imei i have to unlock again
the problem is now ... :
1. write NV from you (successful)
2. write cert from you (failed)
3. i tried doing imei repair (failed)
4. patch certificate (successful)

after patch certificate successful i tried to unlock but it says
