Breaking: Motorola Atrix 4G Gets HSUPA, Not From AT&T
Thanks to XDA developers dew.man and NFHimself, Motorola Atrix 4G owners can now enjoy HSUPA speeds on their Atrix 4G. In order to do this, you will need a rooted Motorola Atrix, the modified SBF files, and RSD Lite, the program used to flash the SBF files to your Motorola Atrix.
Once you’ve rooted your phone, you can download the ZIP file that contains the SBF files that will allow you to flash your Atrix with the 1.87 baseband radio . The ZIP file contains 2 SBF files: the 1.87 baseband radio, which will allow your Atrix to achieve greater upload and download speeds, and the stock AT&T radio SBF, in case you would like to revert to how things were.
In order to flash your Atrix with the files, you will need to use RSD Lite, a program that is used to flash SBF’s on Motorola devices. You can download RSD Lite version 5 here . Download it and install it. In addition, you will also need to download the Motorola drivers so that your computer can properly recognize your Atrix. Drivers are available for both 32 and 64 bit versions of Windows.
Once you’ve installed both RSD Lite and the Motorola drivers, it’s time to flash the radio on your Atrix. Flashing the radio is very simple.
- Make sure that your phone is turned off
- Remove the SIM card and the microSD card. Some people have reported that flashing works fine when you keep it in the phone. It’s up to you. I would remove it, just in case
- Hold on to the volume up button While turning the phone on. Your phone will say “Starting RSD protocol support”
- Launch the RSD Lite program on your computer. It should recognize your Atrix as the device that is connected to it.
- Press the “. . .” button next to the box labeled “Filename”
- Load up the SBF file called att_radio_1_8_7.sbf that was included in the ZIP file that was downloaded. The file must be extracted from the ZIP file. Do not try to flash the ZIP file!
- Connect your Atrix to your computer. If possible, use the USB connection on the back of the PC. RSD Lite should recognize your Atrix and show that it is connected
- Press the “Start” button to flash the att_radio_1_8_7.sbf file to your Atrix. After the phone reboots, you should have higher upload and download speeds
- Test out your new fast speed using your favorite speedtest app
- Remember that you are doing this at your own risk and that we are not responsible if you brick your phone.
Attached is a zip file containing 2 separate sbf files. You will want the SBF for the 1.87 baseband radio which is the same one that shipped with the Telstra 1.4.2 update. It should not require a reset as it’s the radio only, and I have successfully flashed it to my ATT phone using RSD Lite giving me upload speeds slightly higher than my dl speeds (currently showing just under 2Mb).
I am also providing a radio only sdf of the stock ATT radio that recently shipped so that you can go back if need be.
Keep in mind that while it did work for me, this has not been thoroughly tested and I will not be responsible if decide to use this and you brick your phone.
Who needs AT&T if we have XDA, right? Once again, you need a rooted Motorola Atrix 4G, the SBF for the 1.87 baseband radio which was shipped with the Telstra 1.4.2 update and Voila!!. XDA users have reported that their speeds have gone from .3Mbps to almost 2Mbps and I can’t wait to try this! This feels like its Christmas again! Props toNFHimslef and Dew.man from the XDA Forums.
