It depends what you did to it.

Repairability usually hinges first on ability to open the device in a non-destructive way.
Some devices use a lot of double-sided sticky tape.
If you have a supply and the willingness to clean up the original tape and install new tape, that's not a problem.
For many devices it's just a question of working a guitar pick around the edge.

Finding an exact battery replacement can be a problem.
In the past batteries were connected with standard pin/housing connectors.
Now they use teensy-tiny "mezzanine" connectors.
Those are those orange flex cables with a silver plate on top that snap in.

In worst case you can buy raw cells and reuse the BMS PCB, flex, mezzanine.
But don't do that unless you know what you're doing and are a good handworker.
Shorted Li-ion batteries can be dangerous.

Then there are button failures.
In worst case you can replace them with something that does the job but is not a physical match.

I don't know how I missed this, but there is a Firehose loader for QCS2290 (Leaf2, Poke5).

I had an email about this in my mailbox for a long time, but then completely forgot about it. I just tested it on the Leaf2 it works!

The permanent URL for the firehose loader is:

hi,
I can't get a link to the full update.upx for the last update (the one from 2024-07-01)
the usual http://data.onyx-international.cn/api/firmware/update?where={%22buildNumber%22:0,%22buildType%22: %22user%22,%22deviceMAC%22:%22%22,%22lang%22:%22en _US%22,%22model%22:%22Leaf2%22,%22submodel%22:%22% 22,%22fingerprint%22:%22%22} point to the previous update (2024-03-12_10-14_3.5.1_b647384c4) any idea how to get it?

Yup, it's still showing 2024-03-12_10-14_3.5.1_b647384c4.
They roll this stuff out at different times for different models.
Are you sure that a newer version for this exists at all?

[baruch]

I'm pretty sure since it is installed on my device

You're right, I also received an OTA but the link downloads the previous version. the update installed without problems though. I backed up the .upx file if you want it?

Has anyone been able to extract the boot.img from the 3.5.3 update? I don't have access to an EDL cable and trying to decompress the decrypted update file fails since it's an incremental update, not a full one.

No, it decrypts just fine using the standard tools.

I can't be bothered to download 400 MB to check, but there's probably no boot image in there. The boot image is not updated in every update.

You can use EDL to pull the current boot image off the device.
Or you can use the last full update:

Does anyone use KoReader with the 2-disable-hw-button-rotation.lua patch?

Since updating to version my Leaf 2 to 3.5.3 (7f5c78ff3), I've been experiencing crashes whenever I apply the patch and then press the volume up or down button, or swipe to go back.

I tried various versions of KoReader, but it might be a ROM issue, not a KoReader problem.

Interesting lines in crash.log
