Samsung Galaxy S II Odin Download Mode is new to me. Basically, it is used to install firmware, kernel and root Samsung Galaxy S2. Samsung Galaxy S2 needs to be in Odin download mode on these operations.

How to load Samsung Galaxy S II Odin Download Mode?

  1. Turn off Samsung Galaxy S2.
  2. Press and hold down Volume Down + Home + Power buttons at the same time.
  3. Press Volume Up button when warning prompt.
  4. Finally, SGS2 Odin download mode will be loaded.


Custom OS installation warning

Samsung did a great move by letting Samsung Galaxy S2 bootloader unlock. Therefore, lot of developers are developing custom ROM for Samsung Galaxy S2 now compare to HTC Sensation and HTC EVO 3D which have locked bootloader.

    Hello bro, do u use screen protector for ur sgsII? can u specify it and the price

    • http://www.jayceooi.com Jayce

      Nope.

      • rizal

        ok..is it save to leave the screen without any screen protector?

        • http://www.jayceooi.com Jayce

          It depends on your usage. My 18 months old HTC HD2 screen is still free of scratch even without screen protector. I put it in pouch all the time.

    • http://www.jayceooi.com Jayce

      ShootMe, Titanium Backup, MarketEnabler, SetCPU… Just search ‘root’ in Android Market to find out more.

  • Ronnie Lim

    Hard habit to break. After playing with custom rom on HD2, i see that you already itcy to do the same to your new SGS2

  • Danilo

    Hi
    How long it is suppose to take? My SGS2 is about 1 hour with the “downloading screen” and I don’t know what it is doing.

    Thanks

    • http://www.jayceooi.com Jayce

      You need to flash new firmware to it. Else it will stay on this screen forever.

      • vyruzz

        im not sure my previous kernel version but i root with CF KDD..not it stay at reboot screen..what can i do?

        • http://www.jayceooi.com Jayce

          What is your SGS2 model ~ I9100 or I9100G?

          • vyruzz

            I9100

            • http://www.jayceooi.com Jayce
              • vyruzz

                tried..it goes to a screen show disconnection between cellphone and a pc….

                • http://www.jayceooi.com Jayce

                  Hmm… So you can’t load ClockworkMod Recovery or stock Recovery Mode and Odin download mode? If can’t, you need to send to Samsung Support for service then.

                  • vyruzz

                    but i still able to go in download mode

                    • http://www.jayceooi.com Jayce

                      Just install stock firmware with Odin then.

                    • vyruzz

                      where can i get the stock firmware?

      • confused

    Hellow Jayce,

    Thanks for the article.
    I hav a few question to ask,
    Do you know other vendor who not lock the bootloader beside samsung?
    is it still the same : power button + home + vol up to boot in safe mode for sgs ii ?

    • http://www.jayceooi.com Jayce

      Sony Ericsson if not mistaken.
      Safe mode? What is that?

  • rob

    Hi Jayce,

    May I know what is Odexxed and Deodexxed?

    • http://www.jayceooi.com Jayce

      Deodexed == easier to tweak, lighter on ram, heavier on space.
      Odexed == smaller on space, tougher on tweaking and ram usage.

  • sgs2_usr

    Thanks for the explaination!
    But how do one tell that the firmware is Odexed or Deodexed?
    I am currently on XXKG6 2.3.4 for my SGS2, that I got from your site. Is this Odexed or Deodexed?

    Also, can I use odexed update.zip for deoxdexed firmware or vice versa?

    • http://www.jayceooi.com Jayce

      Official firmware is odexed. Most of the custom firmware is deodexed.
      No, odexed update.zip cannot use on deodexed firmware. Same vice versa.

  • ejoy

    elo.. i`m new in adroid.. iwant to root my phone.. but i dont see the odin mode.. how can i get it??
    can u explain to mee..

    • http://www.jayceooi.com Jayce

      Can’t you load Odin mode with above steps?

  • iTh0R

    Hi Jayce,

    Is there anyway I can get the files to upload Bootloader, CSC, PDA and Phone of SGS2. I made a terrible mistake by choosing to download with ODIN’s Bootloader the kernel_i9100xxki3.tar file. The operation failed but after that, I couldn’t do any more downloads with other options. I also have the Firmware upgrade encountered an issue. Please select recovery mode in Kies and try again message.

    Luckily, the phone is still recognized on my PC and ODIN so I am hoping I can correct the issue.

    Thanks

    Rohit

    Hi, I would like to ask for your help. I tried to flash the modem to KG5 using odin. But it stated failed at the end of the process. (it is my first time trying) So I took out the batt and tried to restart my phone but it couldn’t be on. It showed a black screen with a pic of [phone]–!–[com] is at the top left corner of the phone. May I know what can be done to solve this problem?? I am still a noob wiith android. Thanks a lot for any help!

    • http://www.jayceooi.com Jayce

      Is your SGS2 model I9100?

  • Olivia

    Yes it is

  • Silvia

    Dear Jayce,
    I did everything you said (wrote) and now I’ve got my phone in Odin mode ( it was and still is my last hope, i’ve tried many many many ways-my friend’s blocked my phone with trying “too many patterns” ) but what now? It’s been like this for about 5 min. I’d just like to know if I should wait & for how long? (as much as i love my expensive SGs2, i don’t feel like staring at it all day long)
    You’ve guessed right, I’m certainly not into that stuff but thios is my last hope. It really is.
    Thankyou
    S.
