Please help with a GD87 special case
 

Dear Friends,

I have a GD87 to repair and i am studying the forums for the last two days, in order to find a similar situation, but no luck.

This GD87 when switched on reboots continiusly. According to the forums should have eeprom locked.
I flashed it with version A22, but when i use CB2000, although i cover pins: 4, 10, i get on the phones screen the following message:
SE 60010006
CT=L1C1_TSK
L1A: DSP HWT
EST: bad chk

I tried 50 times and only twice i entered the testmode.
I Cleared memory as i should, but the phone continued the same rebooting story.

I also tried to unlock it with crack2b using com1, but the soft can not connect.

I flashed it with versions A39, A51 , always the same.

I request your help now. Lets see what could it be done

Regards
Mike

Processor Problem normally if we get this problem in panasonic GD92/93/75 it should be the same here......

Hi,
I used to have this problem as well. I try to do it on Window XP and it never work fine. So I try it on another Window ME and it works fine.

I flashed it with A21 instead of A22 since A21 is more reliable. After unlock, you will have to flash it back to A39 or A51. If you don't flash it back, the phone will only accept other SIM Card for a litter while only.

Hope this help.
