Advertisement

The developers over at XDA never seem to sleep, always working hard to get things done as quickly as possible, so we the users can reap the benefits. Soon after the leak of the UCLB3 Android 2.3.6 firmware for the Samsung Infuse 4G, a rooted version of the firmware was released. And as always, we have a handy guide to help you flash this firmware on to your Infuse 4G.

Read on to find out how to flash the firmware on your phone.

Compatibility

This ROM and the guide below is compatible only and only with Infuse 4G, model number I997. It’s not compatible with any other device. Check your device’s model number in: Settings » About phone. If it’s not I997, please do not attempt this.

Pre-Installation Requirements/Tips

  1. Infuse 4G with Clockworkmod recovery (CWM) installed.
  2. This procedure will wipe your apps and data. Backup your Apps and important data — bookmarks, contacts, SMS, APNs (internet settings), etc. This Android backup guide would help you.
  3. Sufficiently charged battery, at least 50% is recommended.

How to Install Rooted UCLB3 Firmware on Infuse 4G:

  1. Download the ROM file.
    Download Link  |  Filename: SGH-I997_UCLB3_INFUSE.zip  |  Size: 182 MB
  2. Transfer the downloaded zip file to the root of the internal SD card on your phone.
  3. Turn off your phone and wait for complete shutdown (wait for capacitive button lights to go off).
  4. Then, boot into Clockworkmod (CWM) recovery.
  5. Select “Wipe data / factory reset” –> then Select Yes - Wipe data/Factory reset on the next screen. (This will NOT wipe your SD cards, only your installed apps and app related data.)
  6. Now scroll to “Install zip from sdcard” and select it.
  7. Select “Choose zip from sdcard”. Scroll to the file you transferred in Step 2 and select it.
  8. Now confirm installation by selecting “Yes — Install SGH-I997_UCLB3_INFUSE.zip”. The ROM will start installing.
  9. After the installation is complete, select “go back” and then select “reboot system now” to reboot into the ROM.

That’s it. You now have a rooted UCLB3 ROM installed on your Infuse 4G. Share your thoughts and problems (if any) in the comments below and we’ll try to help you out.

    But if my phone is not root.. how CWM is gonna Work??

    • http://www.theandroidsoul.com/ Kapil

      Yeah, it’s for those who already have CWM recovery on their current (old) firmware/rom. Upgrading via CWM is easy. So, you better install CWM on your Infuse 4G, and then do the above to upgrade it to UCLB3. Search on Google for that, and if you can’t find it after trying several times, let me know, I would try :)

    tried to install but it comes up with an error “signature verification failed” installation aborted.
    what is needed to get past this error?

    • http://www.theandroidsoul.com/ Kapil

      You are trying this from stock Samsung recovery. install Clockworkmod (CWM) recovery first and then do this.

    I got the UCLK2 gingerbread update from kies before it was apparently pulled.  If you also did this you need to root it & install CWM thinger by following these instructions:
    http://forum.xda-developers.com/showthread.php?t=1197248&highlight=root+rogers 

    Don’t worry about the not for at&t thing, that’s b/c it was written before at&t got gingerbread.  I have at&t and it worked fine.  I did that, then followed the instructions on this page, and everything seems to be working normally.

      There’s a fresh link to the kernel on page 11 of the thread there.

    I know these may be silly questions for you veterans, and I hate being a noobie – but I am. I just need to confirm:

    1) I have to root my Infuse before I can even install CWM on my phone, yes?
    2) Furthermore, the UCLB3 isn’t a program that will both root and install Gingerbread at the same time, correct? It is only to install Gingerbread for those that already have rooted phones.
    3) When referring to “your SD card” they are talking about the internal SD card, unless it specifically states “external SD card”, right?
    4) Should I unmount the external SD card before rooting? Some guides say yes, others don’t mention it at all.

    Thanks y’all for your time and dedication to helping those of us that are ignorant about this stuff, but wanting to learn.

      1) Yes. First root your phone and install CWM recovery.

      2) Yes it’s only for those who have CWM recovery installed. But it’s pre-rooted, means after flashing this rom the user will retain Root access and CWM recovery.

      See, UCLB3 is an official firmware, and it doesn’t come with root access. That’s why the developer made this pre-rooted firmware. If you want the normal UCLB3 firmware (without root), then here it’s → http://www.theandroidsoul.com/uclb3-infuse-4g/

      3) Yeah you’re right. But you can always try external SD card if internal doesn’t work.

      4) No. Removing external SD card isn’t necessary at all.

      Let me know if you’ve anything else to ask..

        Shivam, Awesome. Perfectly clear for me now. You answered all my questions & explained it so that I know the “how” & the “why.” I really appreciate u taking the time to help me. Thank you.

          You’re welcome :D

  • qwerty

    No mention of the UCLA3 for the Skyrocket?

  • Max Payne

    I had no video after the install. I fixed it by flashing UCLB3 Stock Kernel. After that I ran into a problem where my SD card is not showing, it’s all greyed out. Any body had this problem?

    • Makwarro

      where can i get the stock kernell?

  • Raichiu

     How do you Boot into recovery? by pressing what?)

  • Wcz

    Hi I’m new to rooting. Will this install Gingerbread on my Infuse 4g? Thanks

    • http://www.theandroidsoul.com/ Kapil

      Yes it will, and it will be rooted one, so use this if you want root too.
      If what you want is plain simple gingerbread update, search this site for ‘infuse 4g gingerbread’ and you’ll get link to install gingerbread firmware.
