On dedicated forums like XDA Developers, a small group of developers is still actively investigating the 10th Gen Fire HD 8. The search for an exploit is ongoing, but much of the discussion is now focused on the complex technical hurdles described above.
For the older 2018 Fire HD 8, developers have created several ROMs, including:
If your tablet is running , the bootloader exploit is patched. You cannot unlock it. Check your version: Settings > Device Options > System Updates. If you are above 7.3.1.9, stop here—you cannot install a custom ROM.
Note: For the 10th Generation Fire HD 8 (codename: kona ), software exploits generally require the tablet to be on Fire OS 7.3.2.2 or lower to utilize software-based unlocking tools like mtk-su . If your tablet has updated past this version, you may need to look into hardware-based exploits (shorting points on the motherboard) or use tools like Fire Toolbox to simply debloat the device instead of installing a full ROM.

Thousands of users have used the Fire Toolbox to debloat their devices, and it’s widely considered a near-custom ROM experience. One user shared, “I have pretty much masked out all the Amazon stuff.
