Hack to Enable HSUPA on Motorola Atrix 4G

Advertisement

The story is long and contains a lot of finger-pointing, but essentially the Motorola Atrix 4G came crippled by AT&T to not allow HSUPA upload speeds. Some have theorized this was to allow AT&T additional time to upgrade their infrastructure before opening the floodgates of all that “4G” traffic.

Users tired of waiting for AT&T to “fix” the problem now have another option and can unlock their upload speeds today!

The hack requires that you’ve rooted your smartphone, have a specialized tool or two, and have applied some modified files. As with most hacks, this one carries with it risk. If you decide to try you’re doing so at your own risk.

0. You must root your phone if you have not already done so.

1. Download and extract the ZIP file containing the SBF file (to let you flash the 1.87 baseband radio). There are two SBFs in the ZIP, the other will allow you to roll your roll back to the older radio.

2. To flash the SBF file you need a program called RSD Lite.

3. You’ll also need the latest drivers to allow your desktop computer to see your Atrix. They are available in both 32-bit and 64-bit flavors.

4. Turn off your smartphone.

5. Remove the SIM and microSD cards.

6. Press and hold the volume-up button while turning your phone on. “Starting RSD protocol support” will be displayed.

7. Connect your Atrix to one of your computer’s USB ports.

8. After you open the RSD Lite program on your computer it should recognize that your phone is connected, if so press the “…” button and select the att_radio_1_8_7.sbf file from step 1.

9. Click the “Start” button to flash the radio. Your phone should reboot after the process is complete.

10. Power down your phone and replace your SIM and microSD cards.

11. Reboot and test your speeds. Your upload speed should be significantly higher.
