Here's a modified version of z4root where I made some changes to make permanent root work on Blades.
Only tested on official Telia Sonera 2.2 but should work on all 2.2 (and 2.1 Blades).

Included in the zip is the modified z4root app + the only source file I changed.

Original z4root source that was used is the one found here: http://code.google.com/p/z4root/

Instructions

• Install the apk (put on sd-card and use "Filer")
  
• Enable "USB debugging"
  
• Start app and tell it to do a permanent root.
  
• Wait for it to reboot your phone.
  
• Have fun!

EDIT 2011-04-16: ver2 attached. This version keeps a copy of the original su and busybox binaries and restores them if you choose to unroot, leaving no visible traces on /system (unless you've modified /system yourself while being rooted)

thankyou for this, will help with the new softbank 003z rom testing

[kallt_kaffe]

If anyone tries this on a stock 2.1 then please report if it worked (it should but as I've converted to Gen2 I cannot test it myself).

Is this safe? Because I've downloaded it and Microsoft Security Essentials warned me immediately that this is an exploit. Exploit:Unix/Lotoor
I think it is, because you have to do "nasty" things to get root access to the system and MSE recognized it as a threat. BTW it's interesting, Microsoft warns you about a Google/Android 'hack'

[hecatae]

it's safe check the source files, same issue with original z4root

The file it warns about is this one: http://code.google.c...eagainstthecage
It's the exploit used to get root access so that the su binary and Superuser.apk can be installed.
If you google "rageagainstthecage" you'll find a bunch of guides on how to use it to root Android phones using adb.

Actually it does warn you for a good reason. If you were downloading an ordinary app that contained this binary it would most likely be a trojan app. However in this case the goal is to hack the phone.

Thank you kallt_kaffe.
When permanent, is it also possible to revert; i.e. unroot back

[ololizoz]

Is it possible to unroot?

[dna108]

Just used it on my stock 2.1 Blade. Took a while, 3-6 mins.
Waited it out, all ok now.  Permanent root success.

Thanks kallt_kaffe

Surely if you've got any worries about the 'need' to unroot you'd just be using the temporary root option?

Is it possible to unroot after a permant root?

A valid question. I'll check the unroot code to see if it will still unroot after my changes to the permanent root code.

EDIT: From the looks of it unrooting should work. However for the trained eye it will leave traces. Not sure it matters but I've made a new version that backup and restore the original su and busybox and removes /system/xbin (if empty) when unrooting. Will post it when I've had time to reflash to a stock ROM to test it.

New version in first post that does a cleaner unroot if you change your mind about rooting.

[Ace Faith]

Thanks so much, man! I see you picked this up from my post in the 2.2 Swedish update thread

What are the advantages & disadvantages of rooting this way?
