11/14/2023 0 Comments Fire hd 10 tabI attempted to turn UART on via fastboot, but any OEM commands I tried were locked (not surprising) The boards on both the 2020 and the 2022 have pads marked RXD and TXD, I tried connecting directly to these without any success, so they must be turned off. If they left UART open on the device, it could lead to a root solution - and it doesn't appear that this has been investigated. If I could figure out what multiplexer these devices use, I might be able to get somewhere, but as it stands, I think it is a dead end. MTK devices usually don't use the ID resistor method on their debug cables, but I did try that as well with various resistances - without success. I built a cable that should have worked the same way, without using the adapter, and got nothing back from the device. That would explain why I couldn't get the baud rate right. I think that what I was seeing was probably just garbage from the USB OTG adapter that I was using. Install custom roms (upgrading Android version)Īny feedback/ideas/brainstorming/thoughts of any kind would be much appreciated!. I guess it would be helpful to mention what my personal end goal with this tablet is: Would anyone have any tips on how to start brainstorming and planning how to find any vulnerabilities within the device/software? Are there certain files on the device I have to look in? Maybe running some scripts or doing some programming? I really wanna see what I can contribute but I just have no clue where to start. Fire Toolbox is amazing and really improves the performance of the tablet. I also don't see many threads for this generation of the device on here, which is why I opted to make this thread.īut seriously, I want to try and tackle this crazy complex puzzle. I don't want to hear that Fire OS 7 is "unrootable". Currently running: Fire OS 7.3.2.1 - Fire HD 10 (2021 - 11th gen)
