TWRP for Amlogic devices.

I feel I'm going ever deeper down the rabbit hole.

I'm learning very little for the growing complexity. For example, I don't know why the data I pulled out of /dev/block/boot was bad. It supplied what seems to be good info to unpackimg until it froze. I don't know what "footer is wrong" indicates exactly. I don't know why unpackimg gave an error on the functioning stock recovery.img. I don't know why the A95X MAX doesn't operate like other TV boxes, allowing communication via USB. I don't know why the manufacturer allowed the box to be rooted, but couldn't produce a box that allowed it to be modded. I don't know why I was pointed to an archive for an app I couldn't compile. And what I have learned from this experience I'm unlikely to use again.

I can only imagine more of the same, when all I was after was to be able to install TWRP.

Thanks for all your efforts, sagert, but I don't think I will be able to install this bloody thing. Best!

Parenthesis:

I found a version TWRP 3.2.2.0 by ViT and it loaded directly from stock recovery into memory. I then tried to install the version from this thread, but TWRP 3.2.2.0 failed to flash saying the file was corrupt! (This may be the result of "footer is wrong". It didn't say.) If I had enough patience I'd try to swap the zImage, but I'll leave that to another day to think about.

Just looked inside ViT's TWRP with RAR and there was no recovery.img. Just a series of directories (etc, licence, res, sbin, system, twres).

Then why not stay with ViTMod and boot temporarily?

It seems that's what I have to do for the moment. I'd like a more stable option rather than having to load it from stock every time.

Having got everything ready to install a system image, I discovered that this version of TWRP doesn't give me the option to flash an .img file to the system partition!

You can convert it to raw using simg2img and then flash using dd from TWRP Terminal.

simg2img system.ing new-system.img -> "Bad Magic"! Your guess is probably better than mine.

Are you using the right version for your OS? https://github.com/rkhat2/android-rom-repacker/releases

Your suggestion of directly loading the ROM into the system partition seems like a great idea, but I am not set up to be able to use uncompiled material.

That's why I gave up with sagert's suggestions, another uncompiled pile from GitHub. There is very little Windows stuff for doing the job you've indicated I need to do to get the ROM into a state so I can dd it. I may as well throw this TV box out for all the wasted effort I've put into trying to make it functional for what I want.

(I'm tired of the obtuse lack of simplicity involved in Windows systems, but now this stuff is far worse. I don't understand why the development community hasn't forced the construction of a platform with a standard interface that all hardware must support, so that you don't have hundreds of little projects all struggling to deal with the diversity of Android devices, but one basic recovery and a far reduced set of parameters to consider for more significant development. Dealing with this unnecessary complexity is a terribly wasteful use of people's skills. And as a consequence those who don't have time to enter the arcane complexity are functionally excluded from having control over their own devices. Just consumers.)

Answer to your question:
How long does a person have to wait between edits of a post? That seems to be the only variable operating here. If I edit too quickly this software has a fit. What's wrong with re-editing a post that causes such fascist software behavior:

You pay for what you get is all i can say

It just happens to the odd person at various times.

Hi ,

best to wait 5min , but for sure more then 1 min , i already had similar Problems with under

Thanks. I guess I'll just have to restrain myself. Beat the cat instead.

Sorry but I can't find any working link for q201 twrp recovery, someone can help me?
thanks

This one works universally: TWRP S905-S912

Sorry, but it doesn't work universally. On the A95X MAX I get the cursed "footer is wrong" error message that no-one can explain when trying to run it from stock recovery, although ViT's TWRP 3.2.2 runs from stock recovery.

[soldiaz]

Ok, so mine does not work but this one ViT's TWRP 3.2.2 can be launched through stock recovery, right?

The file you linked to may work on most TV boxes. I've found that the A95X MAX is a problematic device regarding firmware in general. TWRP S905-S912 may be fine for everything but mine.

And yes, ViT's TWRP 3.2.2 worked on my box via stock recovery. It has a few problems: 1) I can't install it, so that it replaces stock recovery, 2) there's no access to the system partition and 3) the reboot feature doesn't work (you have to use the terminal and send the instruction "reboot".)
