Does anybody know how to repair phones which shows only world map when switching on? Phones without external eeprom chip?
Can them be re-flashed? When can i find flash files for them?
Can Telech flash them in such condition?

And what do you think about that phone:
It was Simlocked with/without card.
I repaired the checksums with sagDr,
> Sim not present with/without card.
I cannot restore original IMEI,
when i change IMEI with sagDr, checksums... OK, but
*#06# > the last digit changed
from 0 to 2. Tried change to original again, than enter manually
field 0 to valid, correct checksums > nothing.

Finally i've tried change the lenght of field 0 to 0 (empty)!!!
And phone died. Cannot turn on, just light, displays world map, and continously restart. I think the phone dead.

If you have restarts after power ON, try to solder flash or even processor with hot air!

I have been killing my phone with SagemDoctor by setting the lenght of field 0 to 0 <empty> (it was a very stupid idea).
Battery charging and Bootstrap mode cannot activate too, because the "mcu" doesn't run, only the world map displayed again and again. I must restore field 0, but there's no external eeprom. I think the only way is to remove the flash chip by hot air, program with a flash programmer, and resolder it. But its too difficult, and i havent falsh programmer. Anyway i bought the phone for only 20$. So i will sale the lcd, speaker, case, keyboard...

NEVER TRY TO SET THE LENGHT OF FIELD 0 OR ANY OTHER IMPORTENT FIELD TO 0 <EMPTY> WITH SAGEMDOCTOR,
BECAUSE IT CAN BE REPAIR ONLY BY PONYPROG, IF EXTERNAL EEPROM EXISTS!!!!!!!

Thanks for your replies.
