XXJVQ — New Android 2.3.4 firmware for Galaxy S i9000!! [Installation Guide]

Page content:

UPDATE: Okay I think it’s worth upgrading to XXJVQ for everyone who uses the Internet browser app, as this update brings the new ‘Internet’ app from the Galaxy S II — which is smooth, fast & has some nice window animations. And btw I forgot to mention before that this Android 2.3.4 update still doesn’t include the new Google talk with A/V.

It’s here, again — the all new Android 2.3.4 firmware (XXJVQ) for Galaxy S i9000. Cheers? Noo. This leak is nothing but JVP with a new name. But still, for the nerd inside me — I’ll upgrade.

For flashing XXJVQ on your Galaxy S i9000, follow the Step-by-Step guide below:

[info]This guide is applicable only for Samsung’s Galaxy S international version (i9000). If yours is Vibrant/Captivate/Fascinate/Epic 4G or any other Galaxy S variant, then this ROM — and Guide — is not for you, and that’s for definite.[/info]

Warning: Warranty may be void of your device if you follow the procedures given on this page. You only are responsible for your device. We wont be liable if any damage occurs to your device and/or its components.

If needed, check out the video at the bottom of this post which shows flashing of an Android 2.3.3 Firmware — XXJVB — on Galaxy S. It would serve as a good guide to flash the Android 2.3.4 Firmware, XXJVQ, too, since the process is totally same. The video is just for reference. You have to follow the steps given below only.

Pre-installation thoughts:

  1. Backup your Apps and important data — bookmarks, contacts, SMS, APNs (internet settings), etc. This Android backup guide would help you.
  2. Disable Lagfix, if you’re using one. Use this Guide to disable/enable lagfix, if you need help!
  3. Drivers! — it’s important you’ve the proper drivers installed. Download links below:

How to Install Android 2.3.4 Firmware XXJVQ on Galaxy S i9000 (international version):

  1. Download the Android 2.3.4 Firmware – XXJVQ. Filename: ‘GT_I9000_XXJVQ_XXJVQ_OXAJVQ_Sbl.exe’. Size: 147.1 MB. Download Link.
  2. Extract the downloaded file ‘GT_I9000_XXJVQ_XXJVQ_OXAJVQ_Sbl.exe’ to get these 3 files:
    1. CSC_OXAJVQ.tar.md5
    2. PDA_XXJVQ.tar.md5
    3. PHONE_XXJVQ.tar.md5
  3. Download Odin3 v1.7.zip from here — Mediafire Link. Extract the zip file to get Odin3 v1.7.exe.
  4. Disconnect your phone if it’s connected to PC.  Switch Off your phone. Wait for vibration to confirm complete switch off.
  5. Now, put it in Download Mode — press and hold these keys together: Volume_DOWN+Home+Power.
  6. Open Odin (from step 3). Connect your phone to PC now. You should get the message “Added! !” under the Odin’s message box.
  7. Important! Do NOT tick the ‘Re-Partition’ checkbox, but keep the ‘Auto Reboot’ & ‘F. Reset Time’ checkboxes ticked.
  8. In Odin, place these files (check out the screenshot given at the top for help):
    1. In the PDA box, select this file (from step 2.2) — ‘PDA_XXJVQ.tar.md5
    2. In the Phone box, select this file (from step 2.3) — ‘PHONE_XXJVQ.tar.md5
    3. In the CSC box, select this file (from step 2.1) — ‘CSC_OXAJVQ.tar.md5
  9. Double check everything said in step 7 and 8 above. Your Odin’s window should look real similar to the image at the very top — which is my Odin’s screen while I flashed the XXJVQ on my Galaxy S.
  10. Now, hit the START button to let the process begin. When process at Odin finishes your phone will automatically reboot. You can unplug the cable now.

    I currently have Official XXJVO (2.3.3), rooted with CF-Root 3.2. Can I install XXJVQ? What are the improvements over XXJVO?

    1. Kapil says: Reply

      Yes, you can install xxjvq.

    Before flashing, out for curiosity, I extracted the files in CSC_OXAJVQ.tar.md5, PDA_XXJVQ.tar.md5 and PHONE_XXJVQ.tar.md5.
    I did the same thing with the ROM downloaded from samfirmware.com.

    By comparing the extracted files I noticed that the samfirmware’s one contains 2 extra files:
    – dbdata.rfs in CSC compressed file (75.3 MB – 79,003,648 bytes, MD5: “81ab6b4bbfa8d1b8c3151c431ca63d74”)
    – cache.rfs in PDA compressed file (1.19 MB – 1,245,184 bytes, MD5: “b9ab3d5f5002547d041d48e773547c12”)

    Does anyone know why these extra files are in samfirmware’s ROM?

    BTW, I hope they are useless. XD

    1. Kapil says: Reply

      Yea…. useless to compare one with another. Use any one set and be sure to
      NOT MIX one with another …. better delete them all and extract one single
      set for use.

    It would be great if you made a video that shows the full steps for this specific release rather than post a video of XWJVB.

      It would take 3-4 hrs while tye procedure is all same…. lemme know if you
      had any problems.

        my galaxy s internet not working after instaling rom.please help.works only in wifi mode but in data mode doesnt work.

        1. Kapil says: Reply

          APN settings are responsible for that. Restore them, if you have a backup, otherwise get these internet settings from your carrier.

  8. do we need to do backup or the phone will automatically do backup..?

    1. Kapil says: Reply

      You need to backup manually using titanium backup free app.

  9. is there ny demerits on upgrading 2.3.4…?
    like anything not functioning …….?

    Hi Kapil ! 
    I’d like to know why i read in other JVQ upgrade tutorials that a wipe/re-partition-format is recommanded before flashing (most of the time to avoid instability) and your tutorial does the opposite (asking not to check the re-partition checkbox).

    My SGS is a SGS 2.3.3 JVB with SFR operator ROM and has been rooted/CWM using your JVB tutorial. I’d like to flash to JVQ with root/CWM. Is CF-root/CWM included in your tutorial or is it only the 2.3.4 flash without special access ?

    Hi Kapil,

    I’m having problems putting my galaxy on download mode.  Each time I do it (like the way it’s been stated here) it keeps just turning the phone on.

    Please help.

    Thank You.

    Why you don’t use the pit file?Why don’t tick re-partition too?I installed the xxjvp firmware but now I want to install the latest firmware xxjvq!What’s the difference to put pit file or not?Thanks!!

    1. Kapil says: Reply


      .pit file re-partitions the phone memory which you don’t need if you used
      the same .pit file earlier or haven’t changed it ever. There is no hardcore
      reason for not using it. As I said in the post too, if the flashing goes
      wrong you can try again using the .pit file then.

      It’s up to you, you can decide to use it, nothing wrong with that. But I
      just don’t prefer re-partitioning my phone’s memory again and again. So,
      unless the process FAILS, I don’t use .pit file which I use upon next

      So, it’s okay if you want to use it. No solid reason for not using it in the
      first flashing. And fyi, I haven’t got any trouble thus far in without-.pit
      file flashing.

    My phone is currently locked to a carrier (Crazy Johns in Australia which uses the vodafone network). Should I unlock my phone before I go through this process?

    1. The android soul fan says: Reply

      Sorry I was meant to type in fan after that. I am in no way associated with this website. Sorry

    2. Kapil says: Reply

      No, I think you can flash it directly. you should be able to boot into download mode. If that’s locked by carrier, you’ll need to unlock the phone first and hopefully that’ll unlock the download mode too. But I think download mode isn’t locked anywhere.

    Hi Kapil.I’m having problems with network conections after i upgraded to xxjvq and i think the update had disabled 3G

    Kapil if you have any thoughts they would be greatly appreciated

    1. Kapil says: Reply

      That happens when the ROM doesn’t have a modem file suited to your region. Download any latest firmware (Android 2.3.3/2.3.4) that’s applicable for your region and extract it to get its modem file. Go to http://www.samfirmware.com/apps/auth/login?why=pw&try=1&wp=1&next=WEBPROTECT-i9000.htm to
      get the region-wise listing of all firmwares for galaxy s till date along with the download links.

      Then, while still on JVQ, go to download mdoe and flash the modem file (of the firmware that suits your region) alone — don’t use the PDA, PIT, CSC Tabs or anything else. Only use the Phone tab and select the modem file there. Keep re-partition un-ticked while Auto Reboot and F.Reset Time, both ticked.

      It’s easy, you’ll soon find out. And your 3G/H will be back too.

        there was the settings from my provider and they give the solution any way thanks for your advice!
        now it’s workin verry good and i’m happy. keep going you’re doing a great job

          Cool. So APN settings were what you needed actually.

    Hi. I’ve upgraded my I9000 from XXJPP Froyo to XXJVQ yesterday. Everything works fine to me, but i’ve noticed that colours of the display aren’t as vivid as on Froyo. I’ve tried with turning off automatic brightness adjustment, but still nothing. It looks as it was problem with gamma correction setting. Does anybody else noticed the difference after upgrade. Is it common problem and is there any way to fix that? i appreciate your help

    1. Kapil says: Reply

      Oh, no idea about. I’ve been using JVQ but didn’t know that, never felt that.

      1. Daniel says: Reply

        Maybe i’ll try downgrading to JVP or even to 2.3.3 tommorow and see if that helps. I don’t know how to express that, it all looks like the display was behind white, very thin fog. Of course i will probably get used to it, but after upgrading difference was noticeable at first sight. I’ll let know if downgrading helped

    Hi there, 

     The Download link (http://www.multiupload.com/RTT74XVG7E) is not working anymore. :((

  25. Kapil says: Reply

    Anyway, JVQ is old now. I would suggest the latest Samsung firmware, JVR, to you — it’s pretty fast.
