The Qualcomm QRD8635 is a Qualcomm Reference Design device made by TCL in 2024. These devices were used for showcasing the Snapdragon 8s Gen 3 platform, as well as a reference design for OEMs.
| WARNING: Every working QRD8635 has Secure Boot turned off. If you see unit with Secure Boot turned on, it has been certainly tampered with, so you must skip it! |
| WARNING: Do NOT. I repeat, do NOT flash vendor firmware onto QRDs! For example, Xiaomi bootloader that gets flashed - the first thing that it will do, is blow fuses and a Secure Boot key to the device. Then it will fail to boot because of the hardware differences. There is no coming back from this point. Secure Boot is now turned on, and can never be unfused back off. The device is now pretty much useless and stuck in EDL forever. Not even EDL peek/poke commands will work, and the phone will only accept Xiaomi firehose files.! |

Obtaining
| WARNING: Make SURE that the device that you will be obtaining at least tries to boot - to a fastboot menu is enough. If not, you will probably end up with a forever bricked device! |
After these devices were used for their desired purposes, some were destroyed, some were recycled, some however were sold and ended up on the second hand market primarily in China. These devices show up on platforms such as Goofish, in varying conditions.
