So just to be clear if i install mantis-6.2.8.1-r2-tz-video-error fix-old-interface-pre-rooted.zip on main OP section I should be good ? I'm currently on rbox firmware 6.2.8.0 . It should not effect efuse doing so ? also would there be anything else I would need to flash after flashing ? I see this post and not quite sure if I need these files its all sorta confusing to me .
I will try to make it less confusing,
it depends on what you want with the system
rbox's latest prerooted firmware is
6.2.8.1_r2 which contains updated TZ (why TZ update is needed? If you are on older OS like 6.2.7.1 which is compatible with tz then almost all aps will work except Prime Video, if you are on newer OS like 6.2.8.0 but are using older TZ then they will be incompatible with each other and you will not be able to watch any DRM contents, it will cause the Device to freeze)
I have not checked what OP has in the ROM, so Skel40 will better tell you about it.
About my post that you quoted, it contains files which will patch 6.2.8.1 only (assuming that the user has only updated the system partition, all of the prerooted images only updates system), you don't need to update other partitions,
The NOFOTA zip will disable System updates on the system, meaning that your stick will not check for update, even after factory resetting or when you are setting your device for the first time (in OOBE), your stick will skip any update and will always tell you your system is up to date (or will throw an error) every time you click on check for update in the "My FireTV Section".
It also enables "AppWidget" which is missing on our stick from ever.
It also fixed Accessibility so that you can use LauncherHijack/FireTVSettings/FTVLaunchX/AnyDesk/MATVT etc.
Accessibility allows you to have Custom launcher (without disabling amazon stock launcher), MATVT allows you to use remote as mouse (its alternative to Mouse Toggle).
It does not uses magisk so it doesn't matter if the system is rooted or not (it is flashed via TWRP)
Now because you are not disabling your stock launcher you can access all the settings
This zip will work on any 6.2.8.1 system (you need to have TWRP to flash it)
It needs the patched boot image so it can boot properly (the boot.img I provided is not patched by magisk so there will be no root, you can install magisk.zip to root if you want)
The TZ update is only for those who are on 6.2.8.0 or 6.2.8.1 and whose Netflix and prime are crashing and do not want to download the full system image. it will patch the OS (it will update the TZ and then remove the files which burns the efuse).
The boot image i provided has some things removed, It does not check if the system is tempered (magisk also removes that and is required to removed, if not removed them only stock images will run on your system and any modification to the system will make it non bootable)
Efuse and recovery service are removed, meaning system will not execute these commands
the function of efuse checker is to check and blow the efuse (my and pretoriano80's boot image will not run it even its present in the system).
the function of recovery is to check if the recovery is stock or not, if it is not stock then the system replaces it(TWRP) with stock (amazon)
as long as you have TWRP installed, recovery script will not do anything but i have removed it just to be safe.
This boot.img is taken from 6.2.8.1
