Alert, 5.12.2 is deploying through the air breaking update.bin.tmp.partial protection.

MaxStirner · 10-20-2019, 08:53 AM

Why not just fill up free space, leaving no more than 200 mb.

To be expected. Is this only devices on 5.12.x though or all using the update.bin.tmp.partial? Does Kual Helper "Prevent OTA updates" do anything that would help?

NiLuJe · 10-20-2019, 08:32 PM

@Waitingforatrain: No, it won't help.

I'm confident update.bin.tmp.partial is useless for sure on 5.12.x, but possibly earlier, too.

It's been reported to work, at the cost of battery life, for the KOA2 with release firmware, by a reputable source that pays attention to details.. Presumably device and particular 5.12.x version need to be taken into account.

I tried extracting the file for the screen savers hack but 7zip shows an error message about the file being corrupted, I download it again but that didn't help.

NiLuJe · 10-20-2019, 10:58 PM

@kalyy: Definitely something on your end. No issues with a fresh download from a secondary laptop here.

(There's approximately a metric-ton of integrity checks involved in the upload process, so a corrupt file making its way to the storage container uncaught is extremely unlikely, FWIW).

As I feared. I will stay in airplane mode for the time being. At some point I will just let it go and hope that I might be able to downgrade as a few have reported. It was fun and all the hard work is appreciated.

Yeah, that's what I do now as last resort:

Code:

#!/bin/sh
x="$(df | grep " /mnt/us" | awk '{print $4}')"  #how much space left in 1024B units
dd if=/dev/zero of=/mnt/us/filler count=1 bs=1 seek="$(($x *1024 - 20 * 1024 * 1024))" #keep 20MB free

Not really convenient and slow (~10 minutes for 1.7GB), but it works.

How well does your device run when it is that full? Can you do wifi syncing without issue? Just wondering. Sounds like a good workaround for now.

That’s what I thought too.
Doesn’t the storage suffer if it has less than 10% of its capacity free?
On SSDs that is definitely the case, it increases the wear level.

hius07 · 10-21-2019, 10:38 PM

I have about 40 MB of free space on PW2, CoolReader runs perfectly.
Installing of the RescuePack required more than 200 MB though.

NiLuJe · 10-22-2019, 12:39 AM

Yup, MRPI will abort if there isn't at least 150MB free. Some packages will implement their own checks and will require more (mainly, Python, which checks for > 325MB).

PoP · 10-22-2019, 07:31 AM

^ That is the idea, isn't it? To inconveniently choke storage so you can get some control back. Then at your choice, erase the filler file, control installs, recreate the filler and re-enable WiFi afterward.

trcm · 10-23-2019, 07:48 AM

Anyone want to try the mount method to prevent removal of the directory ?

Code:

[root@kindle root]# rm -rf /mnt/us/update.bin.tmp.partial
rm: can't remove '/mnt/us/update.bin.tmp.partial': Device or resource busy
