Measuring in at 5.63 x 2.78 x 0.33 inches (HxWxD) and weighs only 5.01 ounces, the Blue R1 HD is a slim and lightweight smartphone. It features a 5-inch 1280 x 720 resolution IPS LCD display with 294 ppi pixel density. The R1 is powered by a quad-core 1.3GHz MediaTek 6735 CPU and a Mali-T720 for graphics processing. The Blu R1 HD is available to Amazon Prime customers for a bargain bin price of $49.99 (with 8GB storage and 1GB RAM) or $59.99 (for 16GB storage and 2GB RAM). It is subsidized by the inclusion of pre-installed Amazon apps and built-in ads on the lock screen. It is also available to non-Prime customers with a price of $99.99 or $109.99 for the 16GB version without ads.
This is a tutorial for converting the Amazon Prime Edition BLU R1 HD to the OEM version. This will overwrite the relevant partitions on your Amazon version of the device with the non-Amazon version. You can also use this method to convert non-Prime to Prime version, and undo Over-the-Air updates or system modifications. This will restore a 100% out of the box image from either edition on your device. This method works on any 16 GB model but it should theoretically work on the 8 GB version as well.

How to Convert Blu R1 HD Amazon Prime to Non-Prime Version
Download the required files from the links below. Some files are quite large, so it might take a while to download.
Note: If the r1hd-spft-scatter.txt file opens in a browser window instead of downloading it, you can save it by pressing Ctrl+S.
If you’re doing this tutorial on a Windows 10 PC with no Mediatek drivers installed, follow this tutorial on how to install the drivers.
Let’s go to the actual flashing of your device.
1. Turn off your device but do not connect it to your PC.
2. Extract SPFT into a folder on your computer.
3. Extract the system image into the same folder you put SPFT in. The three files (boot.img, recovery.img, system.img) should be in the same folder as all the other SPFT files, including the binaries. Use 7zip to extract the files.
4. Run SPFT on your computer then go to the Download tab in SPFT.
5. Click the Scatter-loading button on the far right side. DO NOT click the Download Agent button. When the file picker dialog pops up, find and open the r1hd-spft-scatter.txt file you downloaded earlier.
6. You should see a list of partitions. Only three of them (boot, recovery, system) should be checked, and the location should point to the files you extracted from the tar.gz file earlier. If this is not the case, double-click the location block of the boot, recovery, and system partitions, and select the boot.img, recovery.img, and system.img files from your filesystem respectively. After selecting the files, the boxes should check themselves.From the dropdown in the upper left of the partition list, make sure Download Only is selected. Any other option could damage your device.
7. From the dropdown in the upper left of the partition list, make sure Download Only is selected. Any other option could damage your device.Click the Download button in the upper left.
8. Click the Download button in the upper left.
9. While your phone is OFF, plug it into your computer with a data safe USB cable. The cable that came in the box from the factory is ideal, but any good quality cable will work just fine.
SPFT should start overwriting your phone. If you receive an error from SPFT, unplug your phone, close SPFT, and repeat steps 4 through 9. The whole process takes about 10 minutes, after which you should see a window with a large green checkmark. Once you see that window, you can safely unplug your phone and start it up. You’re all done!
The encryption option on the non-Prime phone is hidden for some reason, to solve this, just install this and run!
