Dead K750i during flashing - GSM-Forum

talkways · 12-01-2006, 01:00

Hello,

I got a K750i which was very slow, thought flashing will do the job. I flashed main flash but it did not effect the speed. So I tried to flash RAW, but unfortunately it stopped at about 84% and after that phone is dead.

Now when I try to attach it says like

System diagnostics passed.
Version 10.05 ready!

[ --- Attach to Phone --- ]
Connecting via Fighter USB Cable...
Powering on the phone...
Baseband chip ID: 0x8040
Protocol version: 3.1
Baudrate = 921600Bd
Phone color: None
Flash certificate: -
All threads terminated.

No suitable applet found.

I searched a bit and found that I should try recovery mode, I did it by selecting Recovery boot, autodetect CID

Baudrate = 921600Bd
Trying CID16 recovery applet...
Sending applet prologue...
All threads terminated.

If I manually select Recovery Boot, CID=36 then I get as

Applet error: 94 00 00 00 00 44
Error flashing block at address: 0x00000000
Script error: Flash error [10.05.75]

Needless to say that I already tried replacing the batteries (Both Phone and external one), tried all baud rates but all same.

Can any one guide me what to do as forum search is not helping me.

Can you please guide, which one is the flash chip (Any picture etc) as I don't want to destroy it completely by doing something wrong.

Hardware problem for sure, probably thats why the phone was slow in the first place.

I just noticed, is your phone a prototype?

Mainboard · 12-02-2006, 10:39

ah yes sorry, I miss that, your phone looks like prototype phone... from who you got this phone?

irfan99 · 12-02-2006, 16:56

what's mean prototype is it change from other phones what's diffrence please mainboard explian here

Mainboard · 12-02-2006, 19:07

hmm prototype is prototype, check dictionary what this means exactly in your language....

prototype phones are used during firmware and hardware development..

@talkways
check label under battery, is there written EP or FP ?

talkways · 12-03-2006, 01:08

It is customer phone and came with the problem that it is very slow. Phone was turning on in first place and now the phone is totally dead. I want to return it to customer atleast in the original condition instead of dead phone. So help is appreciated. So please send me the Flash IC picture so I can do some job. :-))

Mainboard, I checked all the label but couldn't find EP or FP however I am still writing all things so you may check and guide us.

IMEI in prototype phones usually starts "00.." yours apparently dont, if is a hardware problem the phone maybe is sending the wrong information to the program.

If the phone is actually a non-retail, special firmware probably was loaded into the phone.
