How to downgrade software with fullemmi

[Me@n]

I dont know how to downgrade software in motorola phones with fullemmi. I reed in previos articles that you have to do that to unlock new versions. I tryed to downgrade T2288 but the result is always "phone failed contact suplier". I hope there is some good soul that will explain me how to do it.

open you unlock.fdf with text editor and add
that string:
@ seem 1:1 byte 00-03 = 01 02 00 01

flex again you dead phone

p.s.only for t2288

Thank You very much!!!
I know you wrote that it is only for T2288, but is there any solution for other phones( i mean downgradeing)!

Thanks again

This solution works with all telephones, but for miscellaneous models it is necessary to register miscellaneous bytes(original checksum).
for ex:
t,v2288 : 01 02 00 01
for other models other bytes

For their reading I shall use Emmi 038.exe

GOOD LUCK

So you mean if I read the value of those bytes before downgrading, and i restore those bytes after downgrading- the phone will work OK
Only one thing i dont understand: isnt checksum for each version diferent-how can one value work for all T2288!?

Thanks for answering
