* This will only repair 'Contact Service' due to bad Checksum in EEPROM
* This will only repair Checksum Block 1
* If you are not sure about what you are doing, make a backup of the
entire flash first of your phone by reading address 00200000 to
00400000 and the put readed file in a safe place.
* I am not liable to any damages that may happen to your phone while
doing this. If you dont know what you are doing, then might as well
stick to sending Logos and Ringertones...

1. Read Address 003d0000 to 003e0000 using Dejan Flasher
2. Run Hackman 3.21 and open Flash.out
3. Delete first 38 bytes or address 0000:0000 upto 0000:0025
4. Save file as EEPROM.bin
5. Run Bartek Contact Service Repairer 1.0
6. Click 3210 in Phone type and open file EEPROM.bin (You must
see correct IMEI at 'Displayed IMEI' otherwise you are
doing something wrong)
7. Look at 'Counted' Checksum and take note of the 2 bytes
Example: Counted: [8F (143dec)] [33 (51dec)]
* first byte is 8F
* second byte is 33
8. Go back to Hackman 3.21 and open Flash.out
9. Edit address 0000:0144 and put the first byte from Bartek Soft
10. Edit address 0000:0145 and put the second byte from Bartek Soft
11. Save file as Flash.fls and put file in 'c:\nk_files' directory
12. Write to Address 003d0000 with file Flash.fls using Dejan Flasher

i think this procedure by our friend X-Shadow will give solutions for CS for 3210, 5110 and others. its just different addresses...maybe also repair 4-locks closed.

Hello X-Shadow,

Any ideas where EEPROM area is in 3310? How about 6210? I think it is not the same because I try to read also address 003d0000 upto 003e0000 but I do not get IMEI in that area.

Can somebody help me?
