I have one siemens C72 - it was killed during unlock and now - no power on .
I tryed to repair with AllBugSgold ,but I have this message- "some sectors from eeprom full are missing"
When I tryed to write full flash with X65 flasher - I have message "CRC error in flash "
Any idea?
thanks
 
1-try to put your phone in service mode with papau then use eeprom tools for flashing eeprom
2-run papau , go menu flash ,chek pause and replace 76,5008,5009 and do job (you need tp )
 
try to repair with AllBugSgold and use another version of papau
worked for me 100%
 
Destroyed bootcore.
You need original HASH and ESN.
You need a good backup (FullFlash) from a working C72, you must do again a SWUP for your phone like in AllBugSgold, flash your phone, and rewrite a new original flex file.
 
as i know u can't find original Hash if Skey is unknown (of course skey is also calculated from hash and esn) mean can't find original hash, correct me if i'm wrong

@doberman

enter Skey 12345678 in papua and generate new Hash (Bkey will be automaticly calculated)

then find a working C72 Full Flash, and use it for recalculate Full Flash with papua (on Convert Tab)


then Flash ur Full Flash with any free tools (V-Klay or x65flasher1023)
 
Yes, you're right, bourry_GSM. You can calculate new hash, but of course, you need correct ESN.
 
Yes, it is OTP, but if the man used java midlet for calculating ESN, now he need to open phone and do the testpoint for finding ESN. It would have been better if he just wrote down on a piece of paper the original ESN, and now just paste it on Papuautils... because most people just can not make that easy testpoint, resulting a lot of hardware problem after!
 
but i cant write bootcore with x65flasher, write new bootcore with papau then convert working full flash to winswup user
