PW4 Some notes on PW4 issues and resolution - Page 3

My device is still on 5.11.1, and I see no reason to let that upgrade yet.
But for folk on the 5.12 firmware which seems to 'rm -rf /mnt/us/update.bin.tmp.partial', try this in order to prevent that from succeeding....

Code:

[root@kindle]# mkdir /mnt/us/update.bin.tmp.partial
[root@kindle]# dd if=/dev/zero of=/mnt/us/update.bin.tmp.partial/loopfile bs=1k count=360
360+0 records in
360+0 records out
368640 bytes (360.0KB) copied, 0.180811 seconds, 1.9MB/s
[root@kindle]# losetup /dev/loop/16 /mnt/us/update.bin.tmp.partial/loopfile
[root@kindle]# mkfs.msdos /dev/loop/16
mkfs.msdos 2.11 (12 Mar 2005)
[root@kindle]# mount -o ro /dev/loop/16 /mnt/us/update.bin.tmp.partial

Which should result in ...

Code:

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

Not sure how to make that persistent across reboots yet?

Check the 'bridge' code, it may have what you are looking for (systemd example).
Use the 'bridge' code from NiLuJe's snapshots thread, it will be the most recent.

There may even be a pre-set hook for a script in the userstore in there. Although I may be misremembering that

Doesn't seem to be anything suitable in the bridge.sh as it ends with the note "# And don't try anything fancier, the userstore isn't mounted yet..."

I see mention of '/mnt/us/RUNME.sh' in dispatch.sh, but it's not clear to me if or when that is ever called with the necessary {"custom" | "CUSTOM" | "runme" | "RUNME" | r*} flags.

NiLuJe · 08-18-2019, 11:01 AM

Ah, yeah, I was probably thinking of something else (usbnet?), the bridge is too early for the suerstore, as that comment reminded me of

The "Auto Wifi" feature?

trcm · 08-18-2019, 11:22 AM

I could probably tack something into usbnet/bin/usbnetwork.sh, but it doesn't seem entirely appropriate for this.

NiLuJe · 08-18-2019, 12:55 PM

No, I was probably thinking of this.

Although, right now, it shortcuts the rest of the USBNet startup, so, eh, not necessarily usable ;p.

A RUNME.sh shell on the top of visible USB storage can be called from a search bar ;log runme command ...

... as last resort manually, prior to turning on Wifi.

I think for safety, this would have to be automatic, too easy to forget to run this manually and accidentally get updated firmware.
We're not sure it would even work yet
