    Hello, i am use z4root in my ibal andi5li android mobile but z4root is stoped working, and than can not root my mobile, so, how to root my mobile, i am also use superoneclick, onclickroot, unlock root, and binary4, but can not rooted my device, pleas help with working guideline. thank you

  2. i downloaded the apk file from computer and no problem. But when i try to use it on my phone i am stuck up on attempting to access rooting etc. Is there any solutions for this?

  3. i downloaded the z4root and selected temporary root and it said that it was running exploit to obtain root access however this has been running for like 15 minutes with no progress. i have a Lg Revolution. how do i know if it is going to work or brick my phone. ( trying not to brick it)

  4. I tried it on my Samsung Galaxy S (I9000) running Android 2.2.1 and it didn’t work. It got to the point where it says Acquiring root… and stays there for a while, then it exits to the list of all the applications. I rebooted the phone, and tried it again. Same thing happens, I rebooted the phone. I tried it like 4 times, and nothing.

  5. i moved the file to my phone n run it.install blocked then i change to allow installation of non-market app.i run it again it work but after u pressed the ”root” button,it showed me USB debugging must be enabled~ anyone can help me?

  6. z4Root won’t load on my velocity cruz T301 that has 2.2.1 Android on it. I click install and it appears to start to install then it states not installed. Any workarounds?

  7. Is there a way to stop the Android Market from blocking this app? I have an Aria and successfully rooted it when I had Eclair, but the ATT released Froyo was a catch 22.

    Although I like Froyo I have, I believe in open development. I know that within the code there is a way to patch the app so that it gets an LVL (or something like that) that “tricks” the Android Market into thinking it was not side loaded. Is it possible to re-issue this app with the patch? Or am I better to just relfash the phone with CyanogenMod ROM and approaching the issue from there?

  8. Does not work with MyTouch Slide 3G running froyo 2.2. App attempts to apply root for about 10 minutes and then a force close error pops up and phone has severe lag until restarted. Any suggestions? Thanks

  9. I was downloading it from the PC and Panda antivirus warned me this was a trojan.

    Any comments?

  10. For some reason, this does not work for the Huawei Ascend when it’s running Android 2.2

    Works fine on 2.1 however, which is vastly unfortunate.

  11. Hi I’m am along time z4root user and superuser user but z4root does not work on htc devices!!!! So stop complaining that the app is useless or that doesn’t work if you have a htc phone and don’t asked questions on how to make it work if you have a htc phone. Htc has put a band lock onto all there phones so you can not root it!!

  15. Hi, I am trying to root my Motorola spice using z4root. I tried 1.3.0 and it just closes while acquiring root. I tried 1.2.1 and i just says “attempting to apply root…” and nothing else happens. I have reinstalled z4 both versions multiple times, and rebooted the phone multiple times. If anyone has successfully rooted the Spice, please share a hint.
    Thanks so much.

  16. I reboot the phone multiple times and re-installed and booted and every combination of those I can think of….. It all ends in: “Z4Root has stopped unexpectedly.please try again” in the middle of acquiring root shell. I have LG Optimus M. others have done this before and I don’t understand why mine fails (without fail) every time…. sorry I had to throw that in there.

  17. Launched da “z4root” file den pressed da “root” button… Screen went blue 4 a couple of hours…lol

  18. I have a lg ally and when I start it and started to root my phone it just stays in the same window. What’s wrong with it

  19. Hi all. I can see the superuser icon. I would like to enable my phone to see and connect to wireless adhoc networks. I’ve been told that i have to edit the WPA_SUPPLICANT file on my rooted device. I have no idea how to do that. Please help..

  20. i just rooted my lg optimus one. i tried to install android market to it and i did. but after that i opened it and it came force close just like it used to come before rooting.

  21. Waited for about 10 minutes on X10 Android 2.1. It was just showing the busy sign. Used the “SuperOneClick” method instead – A piece of cake

  22. It does not work on HTC wilfire, I’ve tried several times, it either force shuts down the Z4mode app or it restarts, but without the “super user” app on the app list.

  23. what is advantages of me rooting???as my galaxy s bricked shortly after i rooted my first sgs now i have to buy another as it is void of warranty now,only asking as yes it made my sgs lag free(a LOT faster),let me d/load anything instead of market that basically me ?is this why i root?

    1. No it allows you super user access to all system files. Android is a customized version of an OS called Linux which is derived from Unix. Mac was also derived from UNIX. Creating a user gives a GUI with limited privileges.
      In Linux, You have to log in to the root user or use a super user command before doing something in order to get past those restrictions. Rooting your Android is a way of enabling root user access or super user access. its not as secure but it is more flexible. I personally use Ubuntu Linux as 99% of it is free with no strings. And its hard for a NORMAL hacker to mess it up. Advanced Hackers are pretty bad news for any system though.

  24. I just had my samsung vibrant rooted on 2.1 update1. and i just updated it to 2.2 and it erased my root… now im trying to root it again with this same program… it says attempting to apply root for quite a bit… last time on 2.1 it rooted first try in 20 seconds.

  25. Installed this on my SGS, Ive got the z4root and superuser icon but when i bring up the superuserit says ‘no apps in list’ can someone help please? I assume that by rooting a phone i can delete apps I dont use?

  26. TO all those saying that it’s stalling and never restarting:

    Yesterday I tried it, and got the “RUNNING EXPLOIT…” message for over 20 minutes. I figured it was stalled and that this root just didn’t work for my 2.2-Leak Captivate.

    I just retried it, but FIRST I went into Task Manager, shut down all apps and cleared all RAM. The z4root worked in 5 seconds. Obvs, something I was running was lagging the root. Try it and see if it works for you before giving up.

      hey, I had the same problem, when I opened the app I found 2 options, 1 root temporary 2 root permanently, I choose 2, my Galaxy S, re-started automatically, and I found the app superuser, I got wireles tether from the blackmart.apk from 4shared. it seems that is working but when I try to find the wireles name from my computer it does not appear any think, I was wondering, what other tether app should I download, my phone is rooted and the superuser is working, is just the tether app what I am trying to make work

  27. I was able to install the app on my Archos 5 IT, but when I used it, it told me that USB debugging needs to be enabled. Do I have to have ADB installed to use this? If not, where do I enable it?
