In today’s post, we’ll talk about how to unlock the bootloader on the RedMagic 10 Pro (and 10S Pro). Unlike many other Android devices, this phone doesn’t support the standard fastboot flashing unlock command. The usual ENG ABL (engineering bootloader) method is also blocked.
After a lot of research, I discovered that the ENG ABL process on this device is tied to a QR-code-based signature system. Basically, before allowing the bootloader to unlock, the device verifies a digital signature stored inside the ztecfg partition. If this signature matches correctly, the system grants permission to unlock; if not, it denies it. It is currently impossible to unlock the bootloader without correct signature.
How the ztecfg Partition Is Signed
it is not possible to generate the signature manually. It’s generated using a special algorithm which is currently not publicly available. From my partition analysis, I found that it’s a combination of
- eMMC ID
- Serial Number
- UDID
These values are used to create a unique signature, which is divided into 0–11 sections and stored in the ztecfg partition. When you try to unlock, the bootloader match signature against the eMMC ID. If everything matches, the ENG ABL allow permission for the unlock.
So, Is Unlocking Possible?
If you’re trying to do it yourself — no, it’s not possible unless you have access to the correct signing algorithm.
If you’re unable to unlock it on your own, there’s still an option. With the help of a few experienced developers in China, it can be done remotely. The process isn’t free, and you’ll be asked to show proof of purchase before anything moves forward. Contact us to Process..
