Kindle 4 Touch post-hacking problems

[murz_07]

Hello!
I've just recieved my K4T SO, jailbroke it, installed usbnetwork, localization, keyboard localization, auto-rotation and changed margins. Through SSH.
Then I tryed to change screensaver timeout with this script:

#!/bin/sh

# Version 0.01 (20090724) ebs
V="0.01"

# Default timeout in seconds
TIMEOUT=3600

L=/mnt/us/screensaver-timeout_install.log

# Result codes
OK=0
ERR=1

echo >> $L
echo "install: screensaver-timeout v$V, `date`" >> $L

# Give user a way to override timeout
U=/mnt/us/screensaver-timeout
if [ -f $U ]; then
T=`cat $U | head -n 1 | sed 's/[^0-9]//g'`
if [ "$T" -gt 59 ]; then
echo "Using user specified timeout $T from $U" >> $L
TIMEOUT=$T
fi
fi

F=/etc/upstart/powerd.conf

# Make a backup just in case
[ -f $F.orig ] || cp -p $F $F.orig 2>> $L || exit $ERR

K="t1_timeout:"
OT=`grep "^$K" $F | cut -b 13-`
if [ -n "$OT" ]; then
if [ "$OT" != "$TIMEOUT" ]; then
echo "Replacing sleep timeout ($OT -> $TIMEOUT)" >> $L
sed -i -e "s/^\($K\).*$/\1 $TIMEOUT/" $F 2>> $L || exit $ERR
else
echo "Timeout is already set to $TIMEOUT, skipping..." >> $L
fi
else
echo "Addding sleep timeout ($TIMEOUT)" >> $L
(echo "$K $TIMEOUT" >> $F) 2>> $L || exit $ERR
fi

echo "Done!" >> $L
exit $OK


After executing and reboot I noticed battery looking like [__!__]
When I plugged cable in I saw message: "Kindle is not charging now" instead of usual one. And Kindle was not going to sleep at all.

So I restored factory defaults (yes, so naive ) and instead of solving problem I created another one - now I have no root access! I jailbroke it again, tryed to install usbnetwork, but when I press "Update your kindle" nothing happens. It doesnt even reboot. And when I restart it "ERROR 3" appears.

So I assume I ruined some power scheme. I dont know how to fix it.
Any ideas?

You can repair your kindle from diags mode. Additional tools will be provided soon to make it easier.

BTW: Kindle touch is not a K4. Some early posts when it first came out were a little confused on that issue. The number following the K is the generation / firmware major version number, and the latest touch firmware is version 5.0.3. So, the touch is really a K5. Around here, we usually call it a Touch or a KT. The K4 was usually called a K4NT in the early days to distinguish it from the Touch, but the NT part is just a bad habit left over from confusion about the Touch version number. The "real" names used by amazon are the "Kindle Touch" (K5), "Kindle Mini" (K4), and "Kindle Keyboard" (K3).
