MTK 6577 preloader restore - GSM-Forum

dorschdns · 12-05-2012, 11:49

After a flash with a wrong firmware can not boot the MTK6577 phone.
For PC lets you fail to connect.
With the Piranha box can read the pinout but not establish USB connection.
"USB Error"
The same problem I have At another MTK6577 Phone.
Supports this box no MTK6577 CPU?

This Box did not work with MTK6575 / MTK6577 "software - bricked Phones".
The bricked China Phones are unbricked without this Box. This Box did not work!
The Phone Hardware is 100% ok.
I have flashed a new Software at two Phones but one Phone will not work.

The (two) Phones are bricked with a wrong firmwareflash.

-the two Phones cant conect to PC
-the two Phones cant conect to the Piranha Box (no pinout)

Thank you...... ??????

How and what should I flash the new firmware to the phone if it can not connect to the PC and thus not with the SPFlashTool.
No Preeloader is detected.
I thought that these Piranha box can help me to repair a broken flashed phone again. That will not likely.
MTK 6577 Phones are recognized as MTK6575.
Did you personally tested this box with a defective phone MTK6577?
Did you repair this software broken Phone?
With what?
Which driver do you use?
Which PC system?
What unions do you use?
Please do not ever answer this "faulty hardware installed .... driver? ......"
