Thread: Please help - dead C70

Phone was completely working but......... with x65 flasher by mistake i flashed EEPROM with another file - now probably BOOTCORE is erased, how to revive it - phone don't connect with any soft (SST, Papua). I have dump of working phone but how to connect x65flasher to phone without bootkey, hash and any other keys .

sorry for bad english

Use firts this method, if not workiing, use this method!

Hi hacktek! I already read this but.... my phone don't connect. There is hardware fault probably. I changed flash IC with programmed one and phone alive again but still don't connect. . I used cable with autoignition and cable without autoign - both of cables are working with siemens cx65 but with c55 only one of them work. i dont' remember pinout but with this cables i am unlocked many phones ... Autoignition is DTR signal from COMport through diode and resistor 1,5 kOm to pin1 ..... hmmm..... SiMoCo also don't connect with cable for c55 witn c75 and c6v but with cx65 same cable is work .......

Sorry for this post i'm just thinking ........... Tomorrow i'll post schematic of my cable .... and thanks for help

Use a simple RS232 (COM) cable with MAX232! build your own cable! If it will not work, it is a 100% phone hardware fault!

My cable is 100 % working. After this phone i unlock 5 phones CX65 and CX70.THIS c65 won't connect with Papua utils, but with SWUP everything is OK .

So... what the problem is .......................
