1) remove busybox
2) remove su
3) remove superuser
from terminal emulator
mount -o remount,rw /system
rm /system/bin/busybox
from terminal emulator
mount -o remount,rw /system
rm /system/xbin/su
reboot
through settings
uninstall superuser
Backups have nothing to do with it.
If you removed apps the phone came with, it is too late.
Exactly which apps matter is unknown, but I know of no one who removed apps who was able to update.
You are welcome to try it for yourself.
from Removing Root/SU/Clockwork U D G->Removing SU/ROOT<-
- Open the Android Terminal Emulator and you will see a user prompt $
- su (Now you should see a # symbol. This is the SU (Superuser) command prompt)
- mount -o rw,remount -t ext3 /dev/block/mmcblk1p21 /system
- rm /system/app/Superuser.apk
- rm /system/bin/su
- rm /system/bin/busybox
- mount -o ro,remount -t ext3 /dev/block/mmcblk1p21 /system
- reboot
Im having a few problems with my Iconia A100. I upgraded to the new ics then rooted my tablet. I was succesfull in installing a few rooted apps but now for some reason when i go to market and try to install rooted apps its says that there is insufficient memory but i know i have over 4 gb on the tablet and 13gb on sd card. I uninstalled superuser and now cannot get it back. I tried to reinstall ics and re root the tablet. I tried to do a hard reset but does not work! Upon booting says that recovering image failed or something along those lines! The tablet works and i can download regular apps but NOT rooted apps. I want to know how i can just unroot my tablet or get it back to stock, I would rather just reinstall ics and leave it unrooted. Please help???
Hello Paxchristos:
(Little editing for brevity sake)
You know Paxchristos, it caught my attention, from an eariler remark that someone made about removing the bloaded apps on their phones, and then trying to do an update later, which in turns fail to do the update. If I am reading this right, big question mark, it appears that a certain app holdes the key to bring the phone back as it was when first bought. The million dollar question which one of these apps restore the phone back to it orginal state? I guess the next question, perhaps would be, why can't that app be fully restored like the other ones. I would imagine that sounds kind of crazy, but there could be some truth behind it. Just a thought, Paxchristos.

Paxchristos: If I am getting this right, are you saying that when you backup all the files that the commando has, then root the phone, and then some time later you unroot the phone and reinstall the backup files that you saved, but the orginal files are somehow changed, thus preventing a full recovery? If that is the case, now you got me thinking about this.

Paxchristos: ok, you got me thining. I know that you done a lot, but have you actually done, so I do not do what you have already done. I need the files before and after the backup, and also the files after the root is done. Where can I obtain these files, Paxchristos?
My thinking is there is a possibility we are not getting not getting all the orginal files back after we deleted them, even though we have made a compelet backup of these files. I really need to study these files, and no doubt this will take time, probably a lot of time, but that is life in the fast lane.

i've never done a complete nandroid after rooting. first thing i do is delete all the bloat. if you find a way to root the M100 update, I have a brand new, never been used commando sitting right here just waiting to get rooted. then i'd be able to do a complete nandroid with nothing modified except the recovery.
