    • Thanks a ton mate, i was stuck on this error and the link you posted worked.

    • This method does work and we have tried it out ourselves on our Galaxy S I9000. And it definitely does not take hours. Though like any rooting procedure, try it entirely at your own risk because one never knows what can possibly wrong.

52. hello

    i have the same problem with the ” reinstall package”. cant find it.
    I have checked the usb debugging. And i dont have a sd card.
    ive tested the “apply sdcard:updatet” , and its says installation failed.
    I have froyo 2,2.

    / Dennis, Sweden

    if someone can solve or help me with this pls email me a kryddan84@hotmail.com

53. Updating using sdcard:update.zip results in a signature verification error.

54. Galaxy S GT-I 9000 2.2. USB debug mode enabled. The phone doesn’t reboot and doesn’t go into recovery mode. This rooting program doesn’t work at all here. Calling the rootme2.2.bat directly works, but there is no command “reinstall packages”, only “apply sdcard:update.zip”. WTF?

55. doesnt work at all…no option of reinstall package, only update zip appears n if selected the esignature failure is shown

    • works good for me

    Then it says Once your in recovery click the volume button on the left side of the phone until “reinstall packages” is highlighted…

61. No Signature verification failure!

    For FROYO

    First enable USB debugging mode and remove the external SD Card.

    follow instructions here to root galaxy s i9000, see video :

    http://forum.xda-developers.com/showthread.php?t=803682

    after this the device is rooted , reboot your device.

    Download RyanZA’s OCLF 2.0 in the app market , open it and

    click EXT2 and after that One Click Lag Fix 2.2+

    All DONE!!

    • My Galaxy S GT I9000 is already a Froyo 2.2.

      Build number: FROYO.DXJPA
      Kernel version: 2.6.32.9
      root@SE-S604 #1

      I have followed every single step including removing my external, wipe everything in internal SD + debigging mode. I have also installed .Net Framework 4 since i’m using XP 32bit

      Still, i got this error: E: signature verification failed
      installation aborted

      I can’t click on EXT2 tools or OneClickLagFix V2.2
      What have i done wrongly? :((

62. Marco, go to the menu and click, verification toggle or something like that, make sure its disabled and then try updating. cheers.

63. When i try all the steps you described i can apply sdcard:update.zip.

    Then it says — Installing from sdcard…
    Finding update package…
    Opening update package…
    Verifying update package…
    E:signature verification failed
    Installation aborted.

    Ok it doesn’t seem to work. What now???

    I really want to root my Galaxy S with froyo

    Thanks

64. How can you repost this, and leave out important information like which firmware it has been tested with?? Its like you’re trying to brick peoples phones?!

    IF YOU WANT TO USE THIS ONE-CLICK ROOT, READ THE ORIGINAL POST AT XDA (link at bottom of tip)

65. Samthing happened with blake a florida…what can i do now? Mine is gti9000 jp3 running froyo2.2…..tried a lot of times it jist shows e:/signature verification error…

    Pls help!!!hate lags!

    • I have that too! Although you shouldn’t be lagging with Froyo on board!

66. when I try to do it my phone says:E:signature verification failed Installation aborted.
    i’m running froyo 2.2 what did I do wrong?

    • “when I try to do it my phone says:E:signature verification failed Installation aborted.
      i’m running froyo 2.2 what did I do wrong?”

      I get this too, do you have the offical 2.2 update via Kies?

    • Me too! Froyo 2.2 Samsung Galaxy S!

67. Ok, might be being a bit thick here, but, does this only work if you’ve got an external SD card installed?

68. Im rooted on 2.1 eclair. In order to get to 2.2 rooted, do i have to…
    1. unroot
    2. Download official 2.2 froyo
    3. Root with 2.2 froyo

    and does this mean i will loose all my data?

69. It works like a charm. Thanks a million! 🙂

70. Hi..

    I noticed from the start of having this phone that I could not put it into recovery/download mode. Ive tried every steps I found on the internet. (vol up+home+power), (vol down+home+power), vol up+vol down+power) etc.. So I rooted my sgs using the one click rooting software. It worked fine. So when I wanted to install the lag fix, I use the same one click root software but replaced the rooting file with the lag fix file. It also worked fine and my sgs was fast and snappy! But my intro samsung logo graphics was not visible anymore but there was sound, other than that everything worked fine.

    Yesterday I was curious on what will happen if I run the MDS lag fix again. I selected the 1024kb option and it started to create 1gb file again and an error occured and my sgs stalled. I pull out the battery and restart. Came out the samsung galaxy s GT-1900 intro screen. Intro sound effects came out (no logo graphics).. nthen blank screen all the way! Its not booting to the home screen…. Ive tried batt pull and recovery/download mode combo buttons many times! Nothing works.. it just starts up the intro screen + sound and then just dark evil black screen for eternity… I dont know what else to do. Hope you can give any advice. Im running out of buttons to experiment! I think I have officially bricked it. Even flashing wont work until I get my recovery/download mode work in the first place. :’(

71. This did not work for either. I have 2.2 and it gives me error. And it says volume button to toggle and press power, but the power button does nothing.

72. I’m also a Mac user. I get the message;
    E.Verification failed.
    I’ve tried the power key, it’s wrong. I get no result other than a turned off phone. I hit the home key and I get that message. I’ve taken out the SD card and gotten a different error message. ALso, WTF is all this “mounting’ and Unmounting” When I plug in, I get
    1. Charge
    2. Mass Storage
    3. Tether
    there is no other option.
    thank you

73. tell me please , step by step how to make my samsung galaxy s gt i9000 , to root eclair 2.2

74. i get the same error as bob “– Install from sdcard…

78. Won’t work on JPC…don’t waste your time trying

79. wow, this makes a difference.
    The lag fix is incredible.
    I tried this by entering recovery mode on the phone, wrked first time, nz galaxy s

80. hi guys, not working for me , apply sdcard:update.zip n home button, but still giving error in the end… its the internal sd card so the update.zip file should be there automatically or i have to put it there by myself , because the error shows that it search update.zip file in sd card,,,or is there any other step i have to follow,,,thks !

81. Will this method work for Samsung Galaxy 3(I5801, 2.1 Eclair) ?

82. hello guys, I come with some answers…
    I succeeded rooting my phone by
    – selecting apply sdcard:update.zip
    – pressing HOME BUTTON instead of POWER BUTTON

83. Why not to make everyone happy w/o any problem, show us in the video like youtube or etc.. So tat will be aesy for us to follow the steps??

84. I followed every step exactly but nothing happen to my samsung glaxy s. When I click One click root 2.1 button, it shows 1. “Once you’re in the recovery click the volume button on the left side of the phone until “reinstall packages ” is highlighted”. But my samsung didn’t shows anything. Please advise.

85. Thanks, it worked without problems on my new Galaxy S

86. Oh and I’m using I9000XXJP3.. Does it work with that firmware?

87. for the problems experienced by Roy, sam, phill971 and andy:
    connect with your pc but don’t mount! “Reinstall packages” won’t appear either way, but “apply sdcard:update.zip” needs to be done. It fails when mounted (as sam says), but it works just fine when unmounted (like Stellen experienced)!

    • What do you mean with don’t mount? Should I plug it in and then click on “one click root 2.2” (for my samsung) ore how?

88. I’ve tried it too but same problem with the other guys… Then I choosed apply sdcard:update.zip and it failed.. It was saying verification error ore something… How can i fix this?

89. I did the same but it does not work for me, it says no permission.

90. To those of you who had problems. I seemed to have the same. But I chose the “apply sdcard:update.zip” and pressed the HOME KEY not the power button. Then it worked!

91. like andy!!!
    i’ve the same problem!!!!
    suggestions?

92. I’m using a Mac and I can’t open the .exe file. Any alternatives?

93. hey,
    I’ve tried to use your steps, but when I m following the steps from the “on-screen command” something is wrong. It says : “Once you’re in the recovery click the volume button on the left side of the phone until “reinstall packages ” is highlighted” . The thing is I do not have on the mobile’s screen such option(reinstall packages). +
    I have only these :
    reboot system now
    apply sdcard:update.zip
    wipe data/ factory reset
    wipe cache partition

    Any suggestion?
    Thank you,
    Andy

    • apply sdcard:update.zip

      thats the one. hightlight it then press the power button or the menu button. and it will install..

      thanks

    • when I try to do what you have suggested above, the recovery console says it can’t find update.zip at /mnt/internal_sd/update.zip

      what am i doing wrong?

      thanks

94. doesn’t work with JG5. The commands shown in the tool aren’t available on phone’s screen…

95. I’m using JG4.
    it totally doesnt work.
    Some instruction appeard, but never be rebooted.

96. Step 4.. do you mean “One-click root 2.1, your phone needs to be running Android 2.1 Eclair” instead of Android 2.2 Eclair” ?

    • Thank you for pointing out the typo. I have fixed the error.
