The update service checks the phone's CDA and IMEI number and then update with the right firmware pack... meaning you have to change both IMEI and CDA number in order to be able to unbrand the firmware through the update service... so if you want to unbrand it you'll either have to take the phone to some store that performs theese things or get some third party software in order to update the phone yourself

Its just the CDMA number which needs changing NOT the IMEI number....which is technically illegal i think

When i wanted to upgrade my S700 with R3m my CDMA number wouldn't allow it on SEUS...so i changed it with setool to a generic version and upgraded fine

the IMEI number is just a serial number...

I had a couple of setool credits left over from previous firmware updates so i got some help and was able to get it changed....

Not sure whether you can still do it this way unless you already have credits...

You cannot get individual SETOOL credits any more. Ask gbrooks3 about this, he is/was an authorised reseller of the credits.

Just to clear things up a little,

As far as i know, the SEUS checks CDA and TAC part of IMEI to determine its current state and what model it is.

To decustomize new phones, you need a new cable Pinouts are already available - BUT MOST IMPORTANTLY

DO NOT USE POWER FROM USB, YOU WILL FRAZZLE YOUR PHONE, you should not exceed 3v DC input - best thing to use is a regulated power supply. Of mod the PCB with a resitor and zenner diode.

Because the platform sends bogus messages while charging, that is why!!!..But why this change of heart?..We sense a charger connected, oops, we will not shut down after all!!!..*********************** UI BASIC, HOLD YOUR HORSES
