OK so after trying to de-brand my k850i, I deleted a file when using A2 uploader.

i now get the error message
"configuration error, please contact your network operator or service centre"

it was a file out of tpa>preset>custom that got deleted

when i connect it to A2loader it says this on the left side

ChipID:C802,EMP protocol:0401
PHONE STATE: "RETAIL"

i think the deleted file had something written in it saying custom, (it was the last file on the bottom of the list) is there a list of correct files i need in the folder for the phone to work?



i took it to a shop and they told me i needed to try reflashing the MAIN, FS and custom files?

so where can i get these and in what order shall i upload them onto my phone. and to where

many thanks
