backflip to original firmware


How to Restore Your  Backflip to Original Firmware
Cant resist myself to post this guide here as there are a few users who badly want the stock firmware on backflip for varrious reasons. (thanks to John from Australia - a user in one of the forums)


If you are having problems when experimenting (and failing) to put a new ROM onto your Backflip which makes your phone not work (you think it may be "Bricked") then this may be the one thing that get's you out of the fire.

This proceedure below may restore your phone to a state similar to when you bought it. 





 

If you follow the proceedure in this document you will loose all data on your phone. 



If you are in a state where your phone can back up data, I would suggest you do this before following this proceedure.

If you are at a point where you end up on the dreaded "Triangle and Exclamation Mark" screen or your phone keeps starting over and over, then this guide might save you.

In my case, I deleted an importanat file (recovery) on my Backflip, and this did not allow me to use recovery to re-flash my Backflip. It just went into a reboot cycle that would not stop unless I removed the battery.


Step 1:
Download original OEM Firmware (otherwise known as a ROM) for your Backflip according to your country/phone provider. These files will either be in Zip format or, if unzipped ".SHX" or ".SBF" file types. If in Zip, you will need to unzip it.

http://download.cyanogenmod.com/get/update-cm-7.1.0-BACKFLIP-signed.zip

Download the Backflips original ROM according to your country and provider. 

Note: If your phone can boot up to the blue bootloader, you can still flash it with RSD Lite (in case your recovery is screwed too).

Note: You cannot downgrade from firmware with greater secure version to one with lower secure version. Flashing a SBF sets the required secure version for future flashes to it's own secure version (if the flash suceeds)

Step 2.
Download Motorola Backflip USB drivers for 32bit/x86 or 64bit/x64 and install. 

Step 3:
Download RSD Lite program (which will do the flashing of the Firmware/ROM). 
Download and install.


In my case, the version of RSD Lite used was 4.5.7

Step 4:

Run RSD Lite.

Now you will have one screen come up which displays a few mostly empty windows. Connect your Motorola Backflip to the PC with a USB cable.

The Motorola should now show up in one of the lower boxes as a device (one line). If you click on the line which has the newly discoverd device, it will then bring information up to the top left box.

Now go to the top right box and load the original OEM ROM/Firmware you downloaded off the ModMyMobile forum. Locate the ROM that you saved (wherever you saved it).

Your phone should automatically go into Bootload mode (blue screen with "Bootloader" text in small font down the bottom of the screen).

If this does not happen and your phone is not playing nice, take battery out of your phone (at any time) and then ensure the USB is connected to the PC and phone. Reinsert the battery, whilst at the same time, holding down the "D" and "J" keys on the keyboard of your backflip.

The phone should hopefully start up and go to the blue "Bootloader" screen. 

From there, run the RSD Lite program to flash the old Firmware/ROM of your Motoblur and it will slowly (maybe 15 minutes) reflash your phone to it's "As purchased state".

Step 5:

The program will finish (and will let you know if it has been successful or not). You may then shut down RSD Lite, and then disconnect the phone from the PC (always use the "Eject" command from the USB device menu on XP).

Restart your phone, and you should now have a functioning phone that should allow you to try re-flashing a new ROM onto your backflip.

where I download Rom in .sbf format

Lakshmna said...

Akarsh, did you revert back to 1.5 from 2.x.x using the sbf file? or it is an information on how to?

sakarshkumar said...

@Lakshmna i reverted back to 1.5 and 2.2, the post is a result of my personal test experience.

Did you tell me the difference between the 32-bit os , 64-bit os, i need the perfect difference

sakarshkumar said...

@dinesh
the difference of 32 bit os and 64 bit os is that performance is good in 64 bit, u can install 32 bit in 64 bit, but not 64 bit software tools in 32 bit. This post mainly emphasizes on getting you backflip to the retail version if you follow the steps in the post
