now i try to reflash it to v23 with sst but a have an error like you can see in the attachement ( no answer from boot allboot.bin )

i'm tired
 
hi chris,

i already tried with v_klay, sst, fubu, freia(m55).
V_klay = no answer from boot allboot.binWinSwup = No Bootcore detectedfreia = boot file is not acceptedwith sst = nothink, no reaction...strong no?
 
V_Klay: Don't know what be wrong, caus I don't work with v_klay
Winswup: Won't work caus TP is cutted
freia: Don't supports CF62 only at specialy patched version
SST: Solder a z-Diode from Pin 2 to Pin 3 and also from 2 to 4 and you will be able to repair your phone
 
Cf62v21l91full.bin found here : http://www.magboss.pl/soft/Siemens/SST%20%20Usb%20-%20oryginal/
 
Martech 9.6 version stop on 33% on writing during unlock cf62
after that need to repair eeprom i found eeprom v95 and flashes before v95
but fone now on BEEP condition when power ON
its just beep and OFf

any tested experience with that fone

thanks
 
Connect external power supply (4,5V) to phones PCB and try to flash it again with Marztech
 
i did as u said but nothing
i chage firmware like version 85 and others but still buzzzzzz
i thing i need higher version like v95 or very latest
because lower version not acceptable
and m sure there is special version in martech who stop on 33%
i thing its version 95 or v2x
not sure

however if u downgrade and unlock with martech its fine but u have to upgrade fone to upper or smililar version again

thats what i guess
