t20 problem
 

i have 2 or 3 dead t20.....i use flesher to flash it and now thay can turn on...but all of them are sayng.."no acess"

could it be an software problem???

:rolleyes:

1.PA
2.Antenna switch
3. External antenna connector
4. Maybe, just maybe, RF processor

legija....i changed all that.....and nothing...

is there posible that problem is in software???

software and hardware does not match?

1) In most of the cases it is the antenna connector ( best way to check is to solder a copper wire and then check, if working fine 100% antenna connector)

2) The second test can be done with a fancy sticker which lights up when we make or receive a call. If it is not lighting up then it could be a PA or antenna switch problem.

3) If not then it is the RF processor.

But make sure you are not using high temperature while soldering these components and don't **** heat over them . Jus place them and **** heat around them . Cause many of them get damaged while fixing itself , this I found out through experience.

try also to change EEP and resolder the other IC`s

I think it will be a software problem, after flash you must change Eeprom and recalculate crc with varanius soft. It will solve your network problem.

Regards.

rewrite eeprom
