Fire OS 7.2.8.5 (PS7285.2880N/2880) Fs Lite

I went back to 7.2.7.3 from LOS on the sheldonp as posted here and Prime Video simply crashes every time and then the device reboots.

There is a reference to the TZ needing to be updated in this case, so can anyone clarify the exact actions to be performed?

Update: To do it the safest way possible, I replaced the tz image in kamakiri with the one from the latest firmware and bootrom-step.sh flashes that tz image instead. I suppose it is possible to do so from TWRP which would save the effort of having to boot and setup a live Linux environment again.

However, post the tz update, Prime video is working fine.

Fire OS 7.2.8.5 for sheldonp, works fine with the 7.2.7.3 tz.

Is the bootloader still unlocked in 7.2.8.5? My ftv3 is rooted and running 7.2.4.9 but I'm willing to update if I can keep my exploit

Thats fine because TWRP keeps the unlock... i.e. it skips flashing some images, therefore completly safe.

I saw that some people are running into bootloop after trying to ota update their unlocked sticks. Just to be clear, if I need 7.2.8.5, should I manually flash a 7.2.8.5 bin file or just ota update?

The OTA-update App downloads partial 'diff' updates first, but TWRP can't install this kind of update, only full updates are supported. If such an update is placed and pending, the cache recovery commands boots twrp and the install fails. Sometimes this results in a kind of loop, until the update and the commands are wiped/cleared... sometimes the OTA-update downloads a full-update (after a failure of the smaller diff update) and ofc this will work just fine.

I would do the TWRP install, backup infront of it in case something sucks.
PS: My sheldonp stick is still on 7.2.4.2 and the lite stick runs Rogers LOS

Indeed, it is not an issue if you have unlocked it previously. Mine came with 7.2.4.2 when I unlocked it. Tried LOS which was a bit buggy and feature limited in my case, then flashed the latest FireOS again.

However, to have Prime Video working with the latest update, you will need to update the tz image as well (from at least 7.2.7.3). I did it by running kamakiri again with the tz image present in the update zip.

To be clear, the OTA always reboots to TWRP and does nothing, so I always update manually through TWRP after downloading the full zip.

Launcher Manager will also not work directly with the latest updates, but it is easy to set the custom launcher as default with adb root. Those instructions are mentioned in the LM thread.

Also, linking the latest update:
FireOS 7.2.9.2 sheldonp

thanks for the response, I appreciate it.

Also, I've remapped my home button to open wolf launcher using Xposed Edge, thereby negating the need to use something like Launcher Manager. A clear advantage of doing this was also that I can now use custom launcher without disabling Alexa voice commands and fire tv recommendations.

Had issues initially on sheldonp updating to 7.2.9.2 with certain content playing in apps that would just crash the stick. Replaced the tz.img in the kamakari with the one found in the 7.2.9.2 update file and reran the bootrom exploit and now everything works properly.

Anyone got FireOS 7.6.0.3 link for Sheldonp by any chance?
Wish Amazon would let us have a way to automate this instead of needing to manually do this ahah

Hi,

Cheers for sharing.

Can anyone post the original ROM for sheldonp -- PS7242_user_2897_0021710459268.

I have searched but no luck there.

Thx in advance.

I have 7.6.2.4/3337 for the sheldon device, URL has been updated and the older URL still works with older firmwares. Can anyone with a sheldonp device upload this latest firmware?

Skel40 · Feb 27, 2023

I made a TZ Update fix for 7.6.2.4/3337 which can be flashed with TWRP. This fixes the IMDB freezing while playing content and other apps that require this img to be updated. Other versions will be available too on this forum.

I own only the sheldon device and the URL for this is here. Unfortunately its not able to be unlocked anymore. It was patched after firmwares 7.2.8.5 and up. This exploit was unlockable on version 7.2.7.3 and below
