Disclaimer: I will not be held responsible for any damage to your phone, your PC or indeed your life from following this guide. The steps in this guide worked for me. If you have problems uninstall everything and start from Step 4 again. Doing this kind of thing could affect your warranty and all that so have a long hard think about it before you go ahead
This guide will show you how to debrand your Motorola Defy (Eg bought on T-Mobile UK and want generic UK firmware), or indeed restore the phone if you brick (Eg ie removing important apps that you shouldn’t have touched!!)
Props go to jutley for his debranding guide for the flipout, and dkspook for his information in other threads, and anyone else who thinks they may have contributed, oh yeah and my Mum.
##WARNING: Do not flash the newer 2.51 UK Firmware - it is patched and at present root is not possible. Also the Deblur Firmware, is by no means Vanilla - it just has some elements such as the social networking app removed, My advice is to stay on 2.21 UK##
##Disconnect phone from PC##
Download usb drivers here below
I was just flashing the UK Firmware on a unbricked phone. I have actually rooted my phone and this phone is from honk-kong. I was using RSD lite 4.9 to flash the sbf. It went well till 73% and suddenly phone turned off and RSD Lite displayed "Failed, Device disconnected error". Now, I am not able to bring the phone on. When I connect the phone to charger, there is nothing on the phone like it is dead. When I connect phone through USB, I can see white light
Download the debranded Firmware here (To debrand to generic UK I used the one marked UK - choose the one for your country)
Download RSDLite - I used v4.9, I found earlier versions would not work. Get it here.
Install the USB Drivers and the RSDLite program and reboot PC
Extract the firmware file you downloaded a while ago. Then copy the .sbf firmware file to c:\Program files\Motorola\RSDLite folder (installation directory for RDSLite). this should come out as JRDNEM_U3_2.21.0_SIGNED_UCAJRDNEMARAB1B80AA028.0R_USAJORDANRTGB_P026_A007_HWp3_S
rvice1FF.sbf for the UK one.
Start the RSDLite program now where it says filename press the select button and find the .sbf firmware file in c:\Program files\Motorola\RSDLite (it should default to this folder) and select the (sbf) file some details will appear on the right hand side.
We now need to boot the phone into the bootloader (as above make sure the phone is disconnected from USB – not sure if matters tho!). Hold the volume up and then power the phone on, after about 5 seconds release the buttons and the bootloader should display - it will show the version and a battery check. Now plug in the USB cable and it should install the drivers. Once its finished you should see the phone appear at the bottom of the RSDLite program window under `port 1` - Once this is there you are ready to flash the firmware. NB: I had issues getting it to show a number of times. Uninstalling RSDLite/Drivers, rebooting PC, and then reinstalling these resolved this issue.
Press the start button on the RSDLite and just relax while your device gets flashed,debranded etc. you will see a progress status on the right hand side wait till it reaches 100% but please do not disconect it will reboot the phone automaticly and restart the phone.And just wait untill android comes up and fully running untill you disconnect it should read "PLEASE START PHONE MANUALLY" on RSDLite, when this shows it is safe to unplug.
Hopefully now you will have a debranded/unbricked phone.
One thing I noticed is that the data partition stayed intact for me when I debranded, meaning all my settings and installed app (providing you hadn’t moved stuff to /system) were still there after the process – cool! The only thing you will have to do is re-root the device.
Hope you find this useful and I look forward to a great community for the Defy!
