K750 с CID 49 Red: This may indicate damaged EROM area!

[FractalizeR]

Коды читать не стоило, я думаю. Вряд ли это возможно на CID49.
Попробуйте вот так:

Newer phones with locked-down EROM area:
· Be sure to have installed the latest Cruiser firmware restoral package from our support area.
· Connect the phone to the cable and select Normal boot.
· Attach Cruiser to the phone.
· Go to the Security RSA page and press the Unlock RSA button. Remove battery when asked by Cruiser.
This will overwrite part of main firmware by special code thus causing the phone to appear "dead".
· Reinsert the battery and reattach Cruiser to the phone.
· Go to the Security RSA page and press the Restore firmware button. Cruiser will search for a restore file then. If it cannot be found, you will also have to reflash main FW and raw FS and to customize the phone.
· Now go to the Locks page and press the Direct unlock button. Remember, if you encounter any new firmware it is wise to make a security zone backup too (or a full GDFS backup).
