6210 - 6250 conversion problem

[e_costin]

Hi,

Just finished flashing with 6250 MCU + PPM. Then used virgin EEPROM at 5FA000, recalculated FAID. Everything was working fine, the phone registered on the network, all the menus accessible.

The problem:
- when making calls, instead of clear voice I get a very trashed sound, as being in an area with poor GSM signal, but the signal is strong - bar full. Any ideas about this problem ??

Thanks,
Costin

Just forgot to mention, when flashed back with the 6210 MCU + PPM + EEPROM the phone works again fine.

after ugrading it to 6250 try using the nokia tool by pro (build 35)click all in the special factory settings except default imei and click apply SFS..and tell us what happened.. :lol:

Thanks. In fact it was the user data area in the interval 5A0000 - 5AF000 that was not compatible with the 6250. I have just erased the whole flash 2 - 6 and flashed back the 6250 MCU + PPM + EEPROM, restored the phonebook and I have a nice working 6250 now, no more problems.

I have the same problem e_costin. Is there any way you can explain this to me more clearly please. Or better still is there anyway that you can email me the part that needs replacing?

I've flashed the 6250 firmware into my phone, but i can't upload the virgin EEPROM! Every time i try i get a "Boot Init Error" in flasher :confused:

I've cleared the whole flash using kNok, then i've flashed the 6250 firmware into my 6210 - updated FAID - everything works fine, but i get a VERY weak signal!

How do i upload the 6250 virgin EEPROM???

I've tried it with flasher, but every time i get a "Boot Init Error". Please, could somebody explain me what i'm doing wrong?

PS. Is there any IRC channel where you ppl meet?

I've figured it out how to do it.

Thanks for the replies :mad:

After upgrading my 6210 to 6250 (MCU+PPM+Virgin EEPROM), updated FAID, Reset SP Lock, Reset to full factory settings.

If tested it a couple of days and i'm sure that it DOESN'T work in 100%. No menu hangs the phone, but i get a very weak network signal (as mentioned before).

Uploading the virgin EEPROM didn't fix the 1800MHz problem!

I'm sure bout that, cause my operator is based on 1800MHz. When i use a sim from a different operator everything seems to be fine, but the other operator has a strong 900MHz signal, so you can't see the difference!

If anybody is SURE that he has fixed the 1800MHz problem - Please reply

PS. Looks like i'm a spammer :p

No matter what I did I couldn't make it work either... I tried all the eeproms I could find. I even tried older 6250 versions...

The thing I did not try is to manually bring up the AGC and output power level using wintesla (RX_TX calibration).

That should work but I you need special equipment. Look at the service manual for more details. If you can get the equipment (and a working copy of wintesla) I could talk you through how to do it...

Cheers,
