    Post result.
    It IS NOT a display issue. How can a damaged display show K700 as phone model lol??? You obviously don't know that if phone is detected as K700 then it has GDFS problem. Anyone with some experience should know this

    AlexRussell, Backup security units with SETool2lite script, write another K800 GDFS, restore security units. Job done.

    Read this link very carefully and your GDFS will be repaired...

    Re: k800i Flashing White Screen!

    I finally made it to be recognized as K800i again, after doing this:

    Code:
    1. Backup the corrupted GDFS. (Read GDFS)
    2. Create a .TXT file with the follwing contents:
    
     gdfsread:00020e5a
     gdfsread:00020e48
     gdfsread:00010851
     gdfsread:00000006
     gdfsread:0000000E
     gdfsread:00000013
     gdfsread:0000001C
     gdfsread:00000018
     gdfsread:000000AA
     
    3. Save it, name it "readsecunits.TXT".
    4. Select the file in SETool's "MISC" field and press "Write SCRIPT".
    5. Apply the GDFS from a working DB2020 phone of the same model.
    6. Write back the original units. Apply the "secunitsbackup.TXT". (Write SCRIPT)
    Code:
    ChipID:9900,EMP protocol:0301
    PHONE IS RED RETAIL PRODUCT
    FLASH CID detected:52
    Speed:921600
    Flash ID check:897E
    Flash props sent ok

    FLASH CID:52 COLOR:RED

    What should I do next?
    Thanks!

    @boysie, from where can I download another K800 GDFS?

    Please say exactly what you have done and at what stage you are at. You must be really careful when doing this!

    GDFS files can be found in the downloads section.

    Re: k800i Flashing White Screen!

    I did this, but I used my old GDFS backup (when the phone worked), and if I try to start it up, it does the same, flashing white screen and if I connect it again to SETool after starting it up it's again detected as K700.
    Whats wrong? :(

    Code:
    1. Backup the corrupted GDFS. (Read GDFS)
    2. Create a .TXT file with the follwing contents:
    
     gdfsread:00020e5a
     gdfsread:00020e48
     gdfsread:00010851
     gdfsread:00000006
     gdfsread:0000000E
     gdfsread:00000013
     gdfsread:0000001C
     gdfsread:00000018
     gdfsread:000000AA
     
    3. Save it, name it "readsecunits.TXT".
    4. Select the file in SETool's "MISC" field and press "Write SCRIPT".
    5. Apply the GDFS from a working DB2020 phone of the same model.
    6. Write back the original units. Apply the "secunitsbackup.TXT". (Write SCRIPT)

    Well if you have a backup GDFS from your phone, then just flash that.

    Re: k800i Flashing White Screen!

    Nevermind, the problem has been solved, I cleaned the display's connectors and the motherboard connectors and now it's working, but I ran in another problem...when I select "Normal mode", it says "Configuration error. Please contact your network operator or service centre."
