just killed gd75. any revive method ? - GSM-Forum

cos · 10-22-2002, 00:07

I just downloaded the GoldTools and tried to unlock the GD75. The second unlocked (Test Mode) never worked. Anyway, after many tries, I started executing scripts. Nothing happened until I got to "Mfgad75a.g3s" which sayd something like "Warning Full Erasing" and started erasing sectors but blocked after a while and stucked the phone. I tried again and again and even other software, got the battery out to make it start again, but still same thing. After a few days of trying phone died. It doesn't communicate with any software whatsoever, doesn't turn on. It's dead.

Is there any way of reviving it ? Maybe some flash tools or something ? Is it possible to rewrite the flash at this point ? If anybody knows something about this, please reply.

Thanx.

you have just killed your phone :-(

The most important thing to know about panasonic phones is that you NEVER take out battery when something is wrong during flash process!!!Your phone is DEAD.
Only one way to bring it back to life: desolder flash IC,and program it with external flash IC prommer HW.Nothing else can help you.

True ... but maybe panasonic have new firmware comming that prevent the flash bootloaders from being deleted.

Well, thanx for the replies.

Unfortunately, hardware stuff is out of my possibilities.

I'm still searching for software solutions. So, If anybody knows some software way to revive dead GD75, please share.

Thanx

there WILL be a way as panasonic centres must have problems flashing some handsets. maybe a test point or more likely a specific voltage need to be provided to a pin in the phone connector.

if the phone can display something or the LED can light, you will flash it with other soft.

but if the phone no any action, no protools load, no display v1.0.
you must desolde memory.

The GD75 doesn't respond to anything in any way, except for battery charghing, when led turns on red and stays like that until charger cable is removed. That's the only thing it does.

Is that any good ?

if .. that LED is red when charger are connected ..
means is not totaly death

but I think the best solution is to desold the flash and write it ..
