The Amazon Fire HD 8 (10th Generation) is a marvel of budget engineering. For under $100, you get a solid 8-inch display, a 2.0 GHz quad-core processor, up to 64GB of expandable storage, and a battery that lasts for days. But there is a catch: Fire OS.
Fire OS is Amazon’s heavily forked version of Android. It replaces Google’s services with Amazon’s, turns your home screen into a storefront for Prime content, and locks down customization. For power users, this is frustrating. The solution? Flashing a Custom ROM.
By installing a custom ROM, you can transform your Fire HD 8 (10th Gen – codename: Onn) into a pure Android tablet. However, this device presents unique challenges (locked bootloaders, MediaTek SoC). In this guide, we will cover the top custom ROMs available, the installation prerequisites, and why you might (or might not) want to take the plunge.

When looking for a custom ROM for the Amazon Fire HD 8 (10th Generation, codename "Karna"), the landscape is quite different from standard Android tablets like Samsung or Pixel. Because Amazon locks the bootloader and uses a customized OS, the development scene has had to work around these restrictions.
Here is a breakdown of the top features and options regarding custom ROMs for this specific device.
Unlike older Fire tablets or the HD 10 series, the 10th Gen HD 8 cannot be unlocked via software. Amazon patched the vulnerabilities used previously. To install any custom ROM, you must perform a hardware exploit known as the "shorting method" (MTKClient/preloader trick). This requires opening the back case, locating a specific test point on the motherboard, and shorting it to ground while connecting to a PC. This is the single greatest barrier for most users.
Once unlocked (or if you find a pre-unlocked device), three main ROMs are available via the XDA Developers forum, all based on Android 11 (LineageOS 18.1):
Amazon locks the bootloader on nearly all modern Fire tablets (from 2017 onward, including the 10th gen). Without an unlocked bootloader, you cannot flash a true custom ROM (replace the OS). There is no public exploit to unlock it for the 10th gen. What Works & What Doesn't | Feature |
