Don't worry, z4root will work.
STOP SAYING IT WORKS, IT DOES NOT.
MODEL: Ally
Firmware: 2.1-update1
Baseband: VS740MVC.5210.1015
Kernel: 2.6.29 lge@android-build #2
Build: ERE27
SW Ver: VS740ZVC
What happened:
1. Bought phone, had 2.1 already.
2. Rooted with Universal Androot.
3. Barnacle wifi works.
4. Barnacle updates, stops working.
5. Figured id update with the OTA to maybe fix it, stupid I know.
6. Now barnacle definitely doesn't work, I lost root.
7. I try everything possible with universal to get root again, fails everytime.
8. Tried z4root temp and permanent, HUGE fail.
9. Both programs say I have root, it's obvious that I don't.
10. I try to unroot with both z4 and universal, tried factory rest and everything, still fails.
11. Stuck in some f***ed up place where all these root app s say I'm rooted, but I have no su permissions, AT ALL.
12. When opening or accessing superuser app it crashes everytime.
"The application Superuser (process com.noshufou.android.su) has stopped unexpectedly. Please try again."
Notes:
1. Didn't unroot before update.
2. Used ever possible version of Universal Androot AND Z4root.
3. Universal Androot gives "Failed. No ~~~fu goo~~~" error.
4. I hate droid allys now.
5. Stuck between a rooted and unrooted state? Wtf?
6. Z4root does not to my knowledge have an unroot option. You start it and you have 2 options, permanent or temp root.
7. Z4root after doing some research, looks like it needs su for unroot option to show itself, but that's the thing, I rooted, lost root after OTA, and now cannot give permissions to unroot.like I said, stuck somewhere between rooted and not rooted. Somehow I'm rooted with NO SU PERMISSIONS AT ALL. WHAT IN THE F*** HAPPENED!?!?!?!
