thank you,

You can't downgrade erom
You can only upgrade erom
And you can't read the erom from a phone
If you just install the original branded firmware won't that be ok

To be honest, the guys at the service center probably won't even notice that you debranded your phone. I acrually had to repair a bicked phone, took it to the service and they uploaded generic firmware on it so you don't have to worry. And don't flash EROM from a different phone as it could brick your own.

but 2145, if u downlaod erom from topsony, and u write it into your phone isnt that the same thing??? that erom is from a phone...

and erom can be read.. it has an adress like gdfs main and fs.. i think the adress to read is the addres yo have to write.. am i corect??? but the addres is diffrent from erom to erom , right??? so if anyone knows the r3a016 addres, or has the r3a016 erom cid 49 and wants to help me (it isnt in the downlad area:|) please post here...

thanx in advance,
cezar

AFAIK, EROM, just like GDFS is unique to each phone (meaning two k750's have a different EROM), so there is a very small chance pf doing a successfull flash with an EROM from a different phone.

so this means that the erom availeble in the download area is some kind of a script?

EROM = Extended ROM. This is the base part of the software which isn't flashed in normal update operations. It controls the flashing interface, the boot loader, etc.

Nice day

so this means i cant revert to cid 49??? maybe if im flashing another erom... right??
please anyone who has r3a016 cid 49 erom.. please help me..

thanx

You cannot downgrade the EROM CID. But it is no need anyway. You need DB2020 CID52 to be able to apply the patches. If your EROM is damaged then follow the REPAIRING EROM GUIDES for most sonyericsson phones thread.
