Hello everyone! This is my first post here on MobileRead. This is regarding the above mentioned steps and my doubts in each step FOR PAPERWHITE 2 (PW2). I'm thinking of downgrading because many Kindlets are not working as they should in Firmware 5.6.5
I'm using Windows 8.1(Putty for ssh). I'm new to Linux command line and ssh so please bear with me.
1. Backup
This Kindle Touch Hacking explains backup for other systems. DOUBTS: a)How to backup in Windows? b)How to restore if anything gets screwed up? c) Where do I type the Kindle side of the commands?
2. Image
Extracted 5.4.3.2 update file using KindleTool DOUBTS: a)Which PW2 firmware best? b) Do I need to dd any other file to Kindle other than the rootfs.img.gz file?
3. Kindle in USB Mode
Copy ENABLE_DIAGS(file without extension) and rootfs.img.gz to /mnt/us/
4. Reboot into diag then enable ssh
Once the Kindle has rebooted into diags mode, to enable SSH access: N-U-Z-X.
Computer Windows RNDIS Settings IP 192.168.15.201 (netmask 255.255.255.0)
PUTTY Settings IP=192.168.15.244, USER=root, PASSWORD=mario
5. Use dd commands to copy

Code:

zcat /mnt/us/rootfs.img.gz | dd of=/dev/mmcblk0p1 bs=4096

DOUBTS: a) What else to copy (kernel and any other file in extract from update bin) b) Are the above dd parameters right for PW2?
6. Delete /var/local/
DOUBT: How do I do this?
7. Reboot to normal mode

Code:

idme -d --bootmode main
reboot

Are all the above steps correct or am I missing something?
