Stuck in wierd reboot loop

aditya3098 · 09-10-2012, 07:13 AM

I tried to install the vnc package, but after installation, it went into a reboot loop in which the kindle reboots after the firmware loads, but before the home screen is shown. During the loading screen, I can access the usb drive. Please help!

okay first thoughts: please provide a link to the exact vnv package (don't mean to be pedantic but I just honestly don't know exactly which one you mean).
Is this the paid-for one that everyone was complaining about?

You are on a Kindle Touch, *hacked to the core*, it would be good to know if you have any well-known "Gotcha" software installed - Like I dunno Optware or something that always messes stuff up. (as-in better off listing your hacks installed and any little "special" changes you made if any exist)

My instinct (given the place that it is rebooting, I am tracing back through dmesg to see what boots when) would be to attempt to trigger the uninstall via dumping it to the root of the /mnt/us

Whether that will get picked up or you will have to issue command to instigate that process I am not sure.

You say you can access the USB drive. All of it? or just that FAT bit.
as-in is SSH working?

All that info would REALLY help even begin to suggest some actions.
Whether it is me - or someone with more brain cells - who helps you they will most likely want/need that info.

Cheers

One more thought...

Just wait and let it reboot about 20 times. I have had software cause this too.

These are the kind of things I imagine are going on during "Those times"

Spoiler:

So yeah. make sure it is on charge and let it go mental for a bit. see if it sorts it. If you already did that well. meh. worth a try...

Final thoughts - if you DO have ssh. it's probably just stuck something in your init.d's... removing the execute perms on that will at least stop the reboot tide.

Without more data though I dunno... One more thought: I believe this is a "supported package" no? any help there?

If the software is stuck in a tight loop, the watchdog will not be serviced and the SoC will be reset. Which completes the "until fixed { }, repeat" loop.

If anywhere in the instruction sequence, you hit an undefined instruction, the core will take the same exception path used by a watchdog time out (the wd to forces an invalid instruction trap).

And now it's gone and erased the usb drive...

ah. well that appears to be for a kindle 5.1? Unless I'm mistaken.

I have zero experience with what might happen if it installed some 5 hook into a 4.
perhaps someone else has this knowledge

all that said. sounds like a full-on fixup is in order now anyways

sorry mate.
