TWRP for Amlogic devices.

[sagert]

I don't understand this... (I'm coming from a PC background.)

Google tells me:

zImage: a compressed version of the [Linux ...] image that is self-extracting.

I simply extracted recovery.img from the zip file (twrp.u211-3.2.3.0-signed.zip) and flashed it... then tried dd-ing it. My working img file is the one from the zip.

Zimage is inside twrp.It is necessary to change it to your own that works in the firmware.I gave the link as port twrp on xda.This can certainly be difficult not to understand.

Maybe replace zimage with your working zimage in twrp and flash twrp new.

If it fails then it can help porting.

Just to give you a smile... I originally typed "dd if=twrp path of=/dev/block/recovery", literally, but sadly it didn't work.


I eventually got the idea I needed to replace "twrp path" with the path to the TWRP package... which I did: "dd if=/storage/emulated/0/recovery.img of=/dev/block/recovery"

(I assume that I only wanted recovery.img, not the zip.)

dd reporting that it transferred the data.

Rebooting to recovery doesn't succeed: it just boots to system again. This could mean that I've been getting TWRP in the right place, but the A95X MAX doesn't see it.

(Stock recovery is 24mb. This TWRP image is 18.81mb.)

Maybe replace zimage with your working zimage in twrp and flash twrp new.

I am writing english with translation.
1.install terminal emulator with Play market
2. open the terminal emulator and write in it.
1. su
2. dd if=twrp path of=/dev/block/recovery

Just to give you a smile... I originally typed "dd if=twrp path of=/dev/block/recovery", literally, but sadly it didn't work.

3. reboot recovery
And then you get into a new twrp.

I'm out of my depth here, so I'd need help regarding what to do with the partition image and dd in a shell.

But:


I don't understand,

1) assuming this u211 verson of TWRP can work on the A95X MAX,
2) assuming the TWRP app successfully circumvented verification, and
3) assuming the TWRP app successfully flashed the package (as it seems),

why didn't it work? This leads to the question: will it work if I succeed in flashing the package in another manner?

I haven't seen anyone who has posted success getting TWRP or any other system change on the A95X MAX.

Yeah, it sounds like the A95X Max isn't using the Amlogic test keys, so the OTA update is failing verification. You're best bet is to use the partition image. If you have root access, you can do it in an elevated shell using the dd command. Alternatively, you can replace the recovery.PARTITION in an Amlogic burn package and flash with USB Burning Tool.

You can go through the terminal with dd through twrp.

Yo Magendanz!

I can't communicate with my A95X MAX (a u211 box), so I tried to flash TWRP 3.2.3 first using stock recovery, but it didn't pass verification ("E: footer is wrong"). Next I tried with Flashify, but it failed, perhaps for the same reason. Last I tried with the Official TWRP app, which succeeded in flashing, but the A95X MAX wouldn't boot to recovery, going straight to system. I reflashed stock recovery and I could boot to recovery again.

Any ideas? (Thanks.)

Hi, can anyone do TWRP for p201? MXQ Pro 4K p201.img found here works, but when installing ota updates it gives error 7: "this update from p201, this is p200". Are there any solutions to the problem? Where can I find TWRP for p201?

Sounds like your bootloader is intact, so flashing a burn package should be fine. Even if you do corrupt the bootloader, you can flash with USB Burning Tool using Mask ROM Mode by shorting pins on the eMMC. There's a FreakTab topic with more information on that.

Thank you for your help
And one more question :
My device is broken (I mean there isn't any recovery or operating system on it)
But USB burning tool can recognize it
Can i flash it with USB burning tool ?

I haven't built any for the S802H, but you should be able to use the existing device trees with a prebuilt kernel from a k200 reference board (https://forum.freaktab.com/forum/tv-...ference-boards).

It's old, but you could also try this: https://dl.twrp.me/k200/
