K750i White blank display only - GSM-Forum

simpa · 05-30-2006, 23:51

I have one K750i CID36 which after start, shows only white display.
Already customised FS and right after that Shutdown FS.
Problem still remains

Any ideas?

try, dont shut down file system, go to primary tab and turn off phone that might work.

I just done the follwing steps

1. Select exact phone type - K750i
2. Start the phone in recovery mode (via Force RSA recovery mode, CID=36).
3. Repair certificate and turn off the phone.
4. Reattach the phone in normal mode and convert to brown 36
5. Unlock RSA incase the Repair EROM disable
6. Repair EROM
7. Flash K750 full GDFS file and turn Off Phone - reattach the phone.
8. Flash main firmware. - R1AA008
9. Unlock RSA and reattach.
10. Flash raw FS. - R1AA008 and reattach it again.
11. Customize FS by one of the built-in customizations and Shutdown FS.
12. Reattach Again
13. In Tab "Security RSA" tick "Format Security zone" and "Recalculate CRCs" then "write to security zone"
14. Direct Unlock and Convert to Red 36

Nothing changed

Lead, any idea ?

Well R1BC002 and R1CA021_Latest are both WAY newer than the buggy R1N035, sorry to "bust your bubble".....

so, I would use R1CA021 first if I were you....

Please read http://forum.gsmhosting.com/vbb/showthread.php?t=219337 for clarification.

it is blinking and vibrating once after power on, like at a normal power on, but screen is white
i flashed it many times, tried a lot of repair options (certificate recovery, erom repair), but still no changes
now, i am sure it is 98% HW problem
thanks for help guys
