By the way, just recently I was able to update with Onyx upx file, whereas my /system is a bit modified (Lock/Unlock sound files are swapped, and unzip binary is replaced). After the update I had to do these changes anyway.
I guess this is because that was a full update (1.1 GB+). Problem you mention should reveal on incremental updates, right?

P.S. I am sorry for off-topic, but is there a way to replace a system binary systemless-ly? Like, Magisk has system-less hosts file replacement.

The problem is that KOReader relies on unzip's encoding. On my Onyx's Android 10 the unzip binary is ancient and doesn't handle Cyrillic encoding. So I had to replace it by a fresher binary.

OK, sorry, I found an answer to my own question: https://topjohnwu.github.io/Magisk/g...-system-folder

Do you have a Type C OTG adapter? We could use a flash drive, but you'd have to use some automated process.

Hello, USB Type C OTG Adapter will arrive tomorrow.
Yeah seems like it is encrypted now. So not sure how I can push the files now. I get adb access... now I just have to find a way to get it running again, without having a backup at hand but at least the update file as a zip.

It's crude, it's rude, but it does what it should.

[DogilD]

Wow that looks great... so I have a usb stick, I have the OTG cable, I have Update.zip... so what should I do now, that it does as in that picture?
I guess I need to get update.zip on the usb stick (any special format for usb stick needed? like fat32? should it be on a special folder?)

My Thought
1. plug usb c to PC
2. use the File I got to boot into the adb able recovery mode
3. unplug Poke 3 from PC and plug usb stick with update.zip into poke 3
4. what is the next step? or am I completely wrong?

[Renate]

Well, first you need a new recovery from today. The link is in the PM that I sent you originally.

Take your decrypted update.zip (You have used DeBooxUpd.py on the .upd file, right?)
Put it on a flash drive in the root directory.
The flash drive should be formatted with normal "Windows FAT."

You just need to fastboot boot p9mod
It will have the splash screeen saying "Onyx".
Wait until it turns all white. (Even though your PC has bonged to show you that ADB is ready.)

C:\>adb shell

When you do the next step, keep your eye on the display. It should flash white/black/white. If it doesn't, stop right there.

# start ttyscreen

Next:

# start autoupdate

It should say "Waiting for flash..."
Disconnect the USB cable from your desktop.
Plug in the OTG adapter/flash drive and cross your fingers!
Within 3 seconds it should start automatically. Keep your eye on the display. Use a camera to capture any error messages. It may be that we have to add a symlink or something before we run the updater.

Good luck!

[DogilD]

did every step as mentioned, got the white black white screen as well...
got up to autoupdate and then I got this error message

line 6 col 146: unknown function "block_image_update...
line 10 col 146: unknown function "block_image_updat...
2 parse errors

PS: Yes I did use DeBooxUpx.py to create the update.zip from the poke 3 update.upx file

[Renate]

Sorry, my bad. I stuck the wrong update-binary in there.

Load a new version of p9mod from the same URL, it should be 20,766,720 bytes.

Now that you know how it goes, you should be all set.

As I said, the only thing left *might* have to be a prop or a symlink.

[DogilD]

It worked! thank you so so soooo much.
Don't know how I ever can thank you for this.
testing if everything still works but seems like.
quick stupid question. can I now reboot and or turn the device off, or do I need to keep the device on?

anyway. thank you really much

[Renate]

THAT IS SO GREAT!
Thank you for following directions.
I really enjoy when this stuff works out.
I have a new update for my Nook Glow'21 and I will do it this way (just for fun).
Cheers!

Oh, your device is back to normal and you can do what you want.
Without Magisk or something else it will overwrite recovery, so hang on to that last image that I sent you.

Hehe it is actually nice to see all that processing done on an e-ink screen.

Sorry did not understand exactly. So you mean I should not use Magisk? Or you mean I should not use it root to deinstall apps anymore. Never will deinstall there anything anymore ^^"
I will keep that file for sure!!! thank you really so much...

[Renate]

Your device is 100% fine. You can install Magisk if you like.

I just meant, that immediately after the update your device is stock.
Stock devices tend to overwrite recovery using /system/recovery-from-boot.p and /system/bin/install-recovery.sh
It's not a big deal. OTOH, you never flashed recovery, you just ran a different version from fastboot boot.

[DogilD]

Ah understood. Yeah it is okay. Luckely I had the device just 2 days before softbricking it. Thanks to you everything works again. Thank you so so much. I think this issue is now closed. =) thank you again!

I managed to do this exact thing on my Nova Air. How did manage to find the recovery file?
