  1. Dear Mahesh,
    I used the zip file to root my smartphone ‘Samsung Galaxy S2 HD LTE E120L’. I always met the error ‘signature verification failed’. please give me help. thanks.

    1. When you boot into the recovery mode, just toggle “signature verification” to OFF. It should solve your problem

      Thanks !

      1. I have the Bell SGH-i757m I think the Clockworkmod installed but when I go to Root the device and apply the update root_sgs2hdbell.zip i get a message saying E: signature verification failed Installation aborted. Not sure what to do now??? Help please.

          1. You keep saying this, but it is probably the same as my issue. CWM is not installing even though Odin says it did. I tried to post a picture but for some reason it didn’t take.

  2. Dear Mahesh,

    1. Hello Deepak,

      The above procedure works on the Samsung Galaxy S2 HD LTE (SGH-I757M) only. You shouldn’t try it on your device as you may brick it.

      Hope you got the answer to your questions !

      Thanks,

        Hello Dude..I want to know if my Galaxy S2 HD LTE (SHV-E120L) it’s ok to proceed with this ROOT. I think that it’s simillar model.

  3. Can’t get this to work at all. For one: there’s now menu option labelled ‘Install .zip from SDcard,’ or the other one titled ‘choose .zip from SDcard.’ Oh well.

  4. How long does it take to get to the Recovery mode? I left mine for around 5 minutes and nothing happened and couldn’t turn the phone on until I took the battery out

  5. hello.. im from mexico and im having problems with this phone using 3g.. it only appears a G and my internet is really slow.. sms are like 40 characters long..

    1. Hi Peter,

      Please see the title once again, it’s about ROOTING the device, not unlocking it.

      The above guide shows you how you can ROOT your device so you can install root-only apps on it.

      Thanks!

  6. Hi got an issue I hope you can help withhave cwm installed and go through the full flash of the root_sgszhdbell.zip everything goes as planned but when I go to reset the cwm I get ..Root acess possibly lost. Fix ?… (no), (yes – fix root (/system/bin/su), (return) all answers reset phone and I still dont have root access
    I HAVE A SGH -I757M ANDROID SYSTEM 4.0.4 Hope you can help

  7. Ok, I have tried to root my phone 6 TIMES! and it still says Android system recovery for the recovery system. When I try to root it, I get E:signiture verification failed. There is no togle for the signature, probably because the CWM recovery is not being added to the phone even though Odin says it was successful. Anyone have any ideas what is wrong? I have ICS 4.01 as well, which was the update from Samsung Kies for Bell.

  8. Hi,

    I’ve flashed CWM through Odin successfully like 3 times now, but when I boot into recovery mode it doesn’t recognize that it’s there. It just loads the standard Android recovery.

    Anyone else have this problem?

  9. Hello,

    CWM says that the rooting is complete after i installed the zip file however when I run root checker it says that my device does not have root. Any ideas to why this might be happening? Running stock android 4.1.2.

  10. damn it. my device is shv-120l, android ver 4.1.2. after “install ClockworkMod Recovery” the logo “samsung” appear and dissappear and nothing then, my phone breaked.

  11. When I boot into CWM, and I click “apply update from external storage” then I click on the zip folder it loads and then I get the “E:signature verification failed”… I followed both procedures 100%. What is going wrong?
