Still have root after upgrade?

[Topsy]

I cannot find a disable updates anywhere on the phone, am I missing it?

open terminal emulator
enter exactly like this

su
mount -o remount,rw -t yaffs2 /dev/block/mtdblock4 /system
cd /system/etc/security
mv otacerts.zip otacerts.zip.bak
mount -o ro,remount -t yaffs2 /dev/block/mtdblock4 /system

sync

reboot

Thanks for the info!
