Aura second edition v2 keeps restarting and restoring

[Xorecs]

Hiya!

My parent's ereader (an Aura 2nd edition v2) isn't working properly anymore. It keeps booting up into the 'Restoring' screen and then restarts back into the restoring screen. I've tried disconnecting the battery and also tried manually upgrading the firmware on the SD card.

So far nothing fixed the issue though, any idea on how to fix this unit? Would it be possible to create a brand new SD card with a clean image somehow?

Thanks!

Assuming yours has a removable micro SD card, you can replace it with a new one (larger & faster) with the process outlined here:

Is there a card, though? My Aura h2o2v2 apparently doesn't. I havent actually checked because I dont know how to open it but it would be good to know.

There is an SD card inside both versions of the Aura Edition 2. But, so far, we haven't seen an image made for the version 2 device.

Mine is an AH2OV2, not a AE2.

It actually has a SD card, and it's apparently an 8GB card (shouldn't it be 4GB?). I tried creating an image from it and writing it to a brand new SD card, unfortunately I still get the same issues. I think the image itself is corrupted. Any other ideas on how to fix this?

Since it's broken anyways, I would like to try to get the v1 firmware on there. @davidfor, do you have that for me?

That isn't uncommon. They get specced with one size csards, but, for some reason, larger cards are used, generally later in the production. They don't rebuild the image for them.

A corruption on the old card would get copied to the new card.

That definitely won't work. And is one of the reasons we found out about the version 1 and version 2. There are definite differences between the hardware which requires differences in the firmware for them, and one does not boot with the firmware from the other.

Hmm, after some more tinkering I've possibly fixed the issue. The provided SD card wasn't salvageable. I made an image from it (which was corrupted) and got it onto a new 32GB card. When inspecting the old SD card I noticed it had an extra 3gb unpartitioned block on it, but I was unable to expand the main partition due to the SD card being corrupted. Weirdly enough, the main partition was completely full but I was able to write more data to it which would explain the corruption.

After I got the corrupted image onto the new SD card I was able to expand the main partition to 19gb. After I installed this into the ereader it started to restore and restart a few times again and it ended up booting properly (although it's completely reset now it seems). I'll test it for a bit today and see if it's truly fixed.

Thanks for the help guys!

They apparently don't even rebuild the partition table for a size change too. Nothing uses CHS addressing anymore, so this doesn't actually matter, but the CHS addresses in the partition table don't appear to match up with the LBA ones.

A corruption on the old card would get copied to the new card.

For the record, my last SD card failure in a Kobo was a better one (note that it's my own, not the one which came with it) which went read-only, but still with everything intact, and caused factory reset loops because of that. The one before that was actually corrupted, though.
