    I attempted this process a couple of days ago on an LG Volt running 4.4.2 however I get the error “E: signature verification failed” I checked the md5 checksum on the version of update.zip that I have and the one you posted in this article and they match. Not sure how to bipass this error.

  • Larry

    The update.zip file you posted needs to be updated. When trying to load it via recovery it gives error saying signatures do not match. Guide is great though for all steps just need a different file.

    • Larry

      Oh and btw in order to get to recovery do not use adb shell. use adb device to verify phone is connected then use adb reboot recovery to load the recovery mode and it stay in the mode.

      • Larry

        ugh was supposed to be adb devices to verify device is connected. device just pops off a list of commands for adb. it needs to be devices to actually post the device. then adb reboot recovery. If you dont do the adb part in front it just reboots rather than staying in recovery.

        • Galvin Carter

          Updated the update.zip file with another one, you can now just try that one. I hope it will work fine.

      • Galvin Carter

        Sorry Guyz for the inconvenience, download the updated iRoot25r1 and follow the process.

    • Galvin Carter

      I have just updated the file due to which you people were getting the signature error, instead of update.zip download iRoot25r1.zip.

  • Amine

    This method does not work. The “update.zip” fails the signature verification.

    Any help?

    • Galvin Carter

      Updated the update.zip file with another one, you can now just try that one. Download and try once.

  • Larry

    Tried the ioroot25 directions it says on the actuall file but after you do the update from adb part it loses connection to phone gonna try to do the sd card routine with kk-root.zip alone.

  • Mitch

    the kk_root.zip inside iRoot 25r1 has exactly the same md5 checksum as the previous update.zip (the files are an identical match), so unfortunately we have the same signature verification issue. Need to get this re-signed so that the Volt isn’t going to reject it.

  • Jeff

    Hi – Thanks for posting this how to. Unfortunately I am unable to root the phone. I get up to step 7, and when I navigate and select update.zip, the phone gives an error saying something to the effect of invalid file. I can recreate if you want the exact error message. Any help would be appreciated.

    Thanks

    • Jeff

      Never mind – I didn’t refresh page and just now saw above posts. Will check back to see if an file with a new checksum is available.
      Thanks.

  • Alexander

    I tried to root the method said but when i put the option apply update from the SD card i can’t see any file.

    I tried with the two zip files.

    Any Help?

    This didn’t work at all for me. Tried the methods laid out above, and the instructions in ioroot.zip. When the phone goes into recovery, I select apply update from zip, and I get an error saying it can’t mount /sdcard. I’ve had it formatted as ext2, ext3 and fat. Tried the ADB side load, but it loses ADB connection when in recovery.

    Warning: I used towelroot.apk on my virgin mobile LG volt and although it did successfully root the phone, it also made it so I couldn’t connect to Google services, rendering most applications useless on the phone. After a factory reset, the phone remained rooted, and although the Google services did work again, it was only for a few hours. The sync function would continue to fail. I ttroubleshooter to the nth degree to no avail. Luckily I was still with the return date and I returned it for a replacement.

    • Galvin Carter

      I hope you have rooted your device with Towelroot method, there are several tutorial that helps you to unroot your device. After doing that you could restore it to get everything back.
