[RAZR i Q&A, Help & Troubleshooting] SharpnShiny:
Want to downgrade Android version using the RAZR i? Be careful, there are many bricks and things you should know before you do this. Bricked means that the phone is not working or responding to official manufacture software or resetting, essentially a 'hard brick' phone is normally not able to be repaired by the user without exchanging parts inside the phone.

Avoiding Bricked Phones

1. One of the most important rules after you have downgraded/unlocked bootloader is do not accept an Over the Air (OTA) update! Users are reporting that it bricks phones!

2. Do not downgrade from Jelly Bean to Ice Cream Sandwich using RSD Lite, this defnitely results in a hard-bricked phone that cannot be recovered with software. Downgrading using a fastboot can be done yet it is still risky - there are a lot of bricked phones.

Downgrading Jelly Bean to Ice Cream Sandwich

Some users are able to do this while avoiding bricks. There is a huge amount of bricks related to this though. Really know the phone and recovery methods before you try to do it.

Recovering Over The Air brick

If you have unlocked your bootloader and then receive a message notification on your phone or computer saying that there is an update, don't update! This is resulting in a 'soft brick'. If you have a soft brick, download RSD lite (linked below) and flash a ROM.

The Most Common Type of RAZR i Brick

What does the screen say? "Service Required, Code Corrupt"

How? I get about 10 messages per day with this, it's becoming easier to see how the bricks are happening. 1. Using a homemade fastboot or RSD to downgrade from Jelly Bean to Ice Cream Sandwich. Next, the user accepts a Motorola update (called Over The Air). This creates a brick. Then users are trying a popular "unbrick" method which unbricks, then hard bricks. I think the modifcations and downgrade procedures are somehow incompatible, they don't work well together, it is producing the worst kind of brick and it happens here *every day*.

Here I will add links to bricked phones because of the downgrade, there are many more RAZR i threads for bricking from modifications and root in addition to these:

Still want to downgrade? Make sure you have ready enough about recovery etc. and note the huge number of bricks after downgrading Jelly Bean to Ice Cream Sandwich.

Flashing an Original ROM with Motorola's RSD Lite Flash Tool

Use this tool entirely at your own risk. If you modify your phone using this tool, it is your responsibility. This tool is intended to be used by those that have read about ROMs/flashing, including the XDA University guides on this. This should not be used unless you are familiar with these processes. There are many, many new users with bricked phones so don't take this casually! Using this tool to flash wipes all user data. This method of flashing is not known to fix "service required, code corrupt".

The source of this guide is the official Motorola document on this in addition to my own usage.

1. You need to make sure you have the Motorola drivers for the phone installed. You can get them here.

2. You need RSD Lite. You can download that here.

3. You need to download the original ROM that you want to flash. You can download one from here.

4. Your phone should be charged to at least 50%, but I recommend a full charge.

5. Start RSD Lite. Now put the phone in fastboot mode. Connect the phone to the computer.

6. Press the 'browse' button and select the ROM to flash. Your phone should be visible in the lower box on the screen. The ROM information should be visible in the top box to the right.

7. Click the start button. You select the ROM you want and de-compress the ROM. Now flash. When it is finished, it should say that it has completed or failed.
