Repairing K750i

[drdre20013]

I have tried repairing a k750i, After unlocking the handset wouldnt boot, tried setool and got this log:

Open COM port OK
ChipID:8040,EMP protocol:0301
PHONE IS INVISIBLE (FFFFFFFF)
NO VALID FLASH CID DETECTED (463)
skipping empty loader...
Can't load id loader !
Elapsed:8 secs.

Any ideas?

I think that you will have make a full flash ( main, filesystem and cust. ).

Nice day

I also think that you must install GDFS to phone , too , because it don`t detect it ( is invisible ).

Nice day

jasmin: If you find a way to flash a phone which is not even detected then tell me please :p

Which CID is the phone? You have 2 possibilities: 1. waiting a few days with the battery removed, if it's detected afterwards you should flash the EROM and do a fullflash afterwards (I don't think it'll work out)
2. If the phone is CID49 you can testpoint it to get in, flash the EROM and do a fullflash afterwards

But...it's also possible that the flash chip has already died.Then you'll have to replace the flash chip which is quite difficult.

Its CID 49, Its being detected now but says skipping empty loader, possible RECOVERY needed, Ahh another brick for my collection.

i also got my gdfs corrupted and had to flash it with the .bin gdfs

dear drdre20013, u need to switch of ur compter, again reboot without usb dcu 60 cable and uninstall driver of that usb cable named sony ericsson and once again reboot and this time install xs++ and insert ur phone usbin usb port, connect it to phone by holding c button in phone, make sure phone is fully charged and sim removed, and then try to flash, your phone might get recognised and u can further proceed.

buy a tms cable it's cheap and you dont need to be worry of briking your phone becuse it's easy to fix with the tms cable

there is still problem with flashing cid49, or it is solved?
