is it possible to replace flash chip on DCT? - GSM-Forum

sat · 10-16-2003, 10:55

If i have broken flash chip, and replace it with another, does the griffin 2.03 work to rebiuld imei on FLASH chip?
The problem is that nobody have blank UEM. I tried chinese UEM's, and they are all not working, or not blank.
If I have one GOOD UEM from one phone, and GOOD FLASH and UPP from another phone, is that going to work?

Hi,
it possible to change flash and power ic on dct4. If u change power ic, after flashing u must rebuilt imei and power ic must be brand new! China flash and power ic is no problem, if u haven't got a new one u can reflow by a pair of flash and power ic from another phone too! It's test by me!

1. If you change the flash IC only, you can only REWRITE the
same IMEI to the phone.

If you change the UEM with a BLANK NEW one, then you can
change the IMEI of the phone.

2. Griffin can be used to write the IMEI to the phone as well as
other IMEI Rebuilder Boxes out there that uses original Nokia
RPL files.

I am told that there is no quick way to test whether the UEM
is old or new, unless by putting it on the PCB. If the phone
restarts in less than 40 seconds, then it is old... if it doesn't
then it is new. But sometimes even new UEMs have other
internal problems such as loss of voice quality on calls and other
functionalities.

there are no rpl files on griffinteam and griffinbox as well as in forunm sites.

but how to rewrite same imei when the flsah ic is dead (how to create flash data to much uem except fps8)

sat · 10-17-2003, 05:46

as I understood, it is possible to write IMEI that stored in UEM to flash from another phone. isn't it? I will replace DEAD flash with another flash, from ANOTHER phone.

@cmk
To RE-WRITE the same IMEI to the same phone but with new
blank flash ic, you need original equipments for now... Because
you will need to apply for an "RPL" which is specifically made for
your phone. The process is easy, but requires a certain amount
of resources and contacts (for now). Some 3rd party IMEI
Rebuilders can also do this, just as long as it can use original
RPL files then it should be possible. The problem however is
making the "ASK" file (log) and sending it to NoKEyA for a
responce "RPL" file.

@sat
I dont quite undrestand what you are asking.
But I hope my reply for cmk will be clear enough. I dont want to
go into too much detail, unless of course the topic is still not
clear for all.

as i know it must big money if standalone and i think in short time griffin can provide read log function to correct flash chksum hope the log $ can acceptable (cheap than uem)

@ X-Shadow:

I replaced some flash IC's in DCT4, I dont think MUST change imei, only reset SP-locks (and splocks is no problem with current soft) only imei in flash will be 0000000000000's in uem still original (*#waranty* will give 000000000's ) I think biggest problem for most members is to calibrate unit CORRECTLY again after changing UEM (rf and EM part)

When I CHANGED FLASH IC all I have to do is :

-reflash phone
-REBUILD SPLOCKS with neelix, griffin or whatever (so just unlock)
-EM calibrate phoenix + jvb-1
-RF Calibrate+ phoenix + 8922

Thats it phone working no need to rebuild Imei or whatever (phone imei in *#war0anty# = 0000000's) But imei sending to network (*#06# is the one in UEM)

When I CHANGED the UEM all I do is:

-Choose ANY RPL file I have in my "database" or make a ASK file
-Connect 12v to JVB and connect via fps8
-use the "wizard" to complete it.

After this, phone get IMEI and PRODUCTCODE from RPL file I choose. When connecting to wavetec NET tester I see IMEI I JUST make in NEW UEM. When looking via *#war0anty# I see "imei in flash(old one)"

-REBUILD SPLOCKS with neelix, griffin or whatever (so just unlock)

WHAT TO USE TO CALIBRATE IT?
