rebuild 8310

I answer to your " provocation ".

1. UPP replacing on a 8310 doesn't happen anything.
2. replacing UEM and FLASH loses imei.

After having replaced UEM or FLASH it is created a file .ask to send Nokia to the server in Firlandia.
Example file .ask:

[SER_PROG_DATA_IN]
IMEI=3507xx/xx/xxxxxx/x
PRODUCTCODE=050xxxx
DONGLE=45xxxx
CHANGED=1
DATA=0002ACE3700C0D2DFD39268F84CAF1EDA5D8F4996CD2F313D1F39DCC87A15FFF169AD0670D464507BEBDC4359AB906F255D674E400AE01202DA0305C152BC336353329CE457415D6B81E
DATE=2003-xx-xx xx:xx:xx
CHECKSUM=18590

[SIM_PROG_DATA_IN]
TYPE=2
IMEI=3507xxxxxxxxxxx
PRODUCTCODE=050xxxx
DONGLE=45xxxx
CHECKSUM=-6167

The answer is a file .rpl that allows to write again the imei.
Example of file .rpl :

[SER_PROG_DATA_OUT]
IMEI=3507xxxxxxxxxxx
DATA1=26DC323E72683D98BD4F292B5FE96BA42C0DDAD7C27D3A5FADA43EEB84434AF6B9CF16A451D9B1F2

I hope for to have been clear in to say that you/he/she is codified.
I intended to say that it is very difficult if not impossible to write the imei on a 8310 (7210,6610,6510,7650,ecc) changing a component BGA or alone rewrite.

P.S. you Excuse of mine bad English.
