Z4root – The Newest 1-Click Root Solution for Multiple Devices


XDA’s done it again, folks. Developer RyanZA has introduced his latest application – named Z4Root – which should make the rooting process brain-dead simple for anyone with an Android phone regardless of what phone they’re on. I’m not sure which devices he “officially” supports, but he doesn’t specifically mention a list of devices so I’ll assume all. To be on the safe side, Droid-Life has a list of devices confirmed to be compatible so far:

  • Droid X
  • Droid 2
  • HTC Hero
  • Galaxy S devices

I wish I’d known about that last bullet point before sending my Epic 4G off to Samsung due to USB problems. (Rooting it was the only reason I cared to even ship it off.) Ah well. If you have yet to bite the bullet on rooting your phone and want an easy (and apparently failsafe) way to do this, then give it a shot. Make sure you take a scroll through the thread on XDA before you do, though, to ensure that you won’t come across any problems if you attempt to apply it. Anyone out there willing to risk their phones to beef up this list of confirmed devices? Let us know if you were successful if you have tried it out. [z4root.apk – right click, save target as]

The "Google Phone" sounded too awesome to pass up, so I bought a G1. The rest is history. And yes, I know my name isn't Wilson.

  30. I just used this on my Galaxy S i9000 running Froyo JP6. The phone was rooted. On my phone, this app works as claimed. On that basis, I also installed the One Click Lag Fix (OCLF) v2.2.8 by the same author, also in the Market….and now my phone is blazing fast. Wow. What a difference! I’ve been using stock Froyo for the past month and was becoming quite frustrated by the serious lag that occurred at times….waiting literally minutes for the phone to either respond or FC that app I was trying to use. TwyDroyd Pro was an app that seriously lagged….sometimes failing to open at all. But with OCLF installed and the lag fix applies, Twydroyd is back to working well and quickly. yay!

  52. I did it with my Galaxy S vibrant, with no problem!!! and Installed Barnacle wifi Tether… now I’m WIFI tethering, SWEET. I wanna know if it will be a good idea to try it with a Motorola Cliq. Thanks

  54. Worked on my Droid X. Very simply to install. One prob though, I deleted the Blockbuster app but the icon is still on my apps list. No biggie.

  55. Hi, z4root work great in my droid x 2.2 froyo

  56. No luck with my EVO. No superuser in directory. Also checked by typing “su” in a terminal emulator.

    I’ve run z4root twice now on my phone. It’s rebooted and looks like it’s rooting. But it doesn’t.

  57. I have an LG Ally and it was already rooted my phone then did an automatic update to version 2.2.1 and when i went to use Barnacle it said it didn’t have su permissions so i tried to re-root my phone adn it continuously gets stuck on the running exploit in order to obtain root access page… does anyone have any help/advice?

  58. hey the app is gone from the market… anyone help me with this??? thank you! [email protected]

  59. I just installed Z4 root on the Huawei Assend M860 Andriod fone from METROPCS. Be sure when you go on the developers web page download the 1.3.0 APK file. The standard 1.1.0 is just a shell app it “WILL NOT ROOT YOUR PHONE” if done correctly will work flawlessl. bottom line is u can’t screw this up. Only if your a NOOB. Good hacking my friends.

  60. been trying all night. updated vibrant to the 2.2 through mini kies and cant get z4 to work i have treid and tried and tried. pulled the battery gets hung then vibrates and tells me that the app forced closed

  61. how and where you find the z4 root 1.3.0 apk file,any link,what’s the process to root the Huawei Assend M860 Andriod fone from METROPCS,do you stall direct to cell phone or to the pc first??? thank-you.

  62. I got it,thank-you every one.I isntall the z4 root in my micro sd card 1.3.0 apk file ,it worked.

  63. I successfully rooted both my Huawei M860 and ZeniThink 2. Running Barnacle Wifi tether I was able to use the Huawei to tether my laptop. Very good connection I might add. The ZeniThink does not see the Barnacle hotspot. I’ll let you know when I’ve been able to figure it out. Something about Android devices not liking ad hoc networks.

    Oh, by the way, do not try to download Z4 Root on a WIN 7 64 bit system. It sees this as a virus. I downloaded it on the ZeniThink, then copied it over to the Huawei. Works wonderfully on both systems.

  64. how long is it supposed to take to root?

  65. Josh
    Just wondering how this worked for you. Tried both the temp and permanant. runs through the process then just goes to my home screen with no super usere. Also using Vortex.
