To make it clear and simple about this blog is that i’ve just finished upgrading my Motorola Atrix 4G (AT&T) to ALIEN ROM by kennethpenn which runs on Gingerbread 2.3.4 ( AT&T 4.5.91 ) and i’ve found out that although it’s not that difficult to do so, it inevitably took quite sometime for a noob like me to flash ROMs on an android device back and forth without risking myself to BRICK the phone!!!. Fortunate to me that i’ve managed to do so without hassles. However, this came with a few hours of research before given my hand on the flashings. The guides to do so are everywhere on Google and xda-developers website, however there are no direct instructions just yet and here you go…..
Please note that in this instruction, I am only a person who collect guides from different sources and combine&organize them for you. All credits & files download links here are NOT mine. Each sub-instructions here will be referred back to original posts/blogs/threads….
[Flashing at your own risks, and I’m not holding any responsibilities to any damage caused to your device
This method is working on mine and my intention is just wanting to share ^.^ ]
First of all, if your ATRIX 4G is
- GINGERBLUR (i was running on 4.5)
and your aim is to either upgrade your ATRIX 4G to
- Gingerbread 2.3.4 [STOCK]
- Alien Rom V4
Then you are good to go 😉
The 1st step:
Flash your Atrix4G from MOTOBLUR back to AT&T Official 1.8.3 version.

Complete all prerequisites and follow all instructions.
You need AT&T Official 1.8.3 version so please google and look for “OLYFR_U4_1.8.3_SIGNED_OLPSATTSPE_P013_HWolympus_1g_Service1FF.sbf”
Done? .. Congratulation and welcome to AT&T Official 1.8.3 Stock Rom.
The 2nd step:
Flash your Atrix 4G from AT&T Official 1.8.3 version to [Stock ROM] Gingerbread 2.3.4 ( AT&T 4.5.91 )
