Telus Samsung Galaxy SII X Jelly Bean Update Released (4.1.2 T989DTLUMC4)

Yet another day passes by, another Jelly Bean update to a Samsung Galaxy device. Todays treats: Telus Galaxy SII X  (also known as SGH-T989D and previously Hercules). I thought Samsung has forgotten this device already, but after seeing T-Mobile’s Galaxy S2 SGH-T989 version getting Jelly Bean last week,  I already knew that Telus will  come up later since both variants are identical to each other. This update is now live via Samsung Kies, all you need to do is download the latest Kies from Samsung website, then make sure your device is fully charge, connect your Galaxy S2 to the computer then check if the update is available.

Here’s the screenshot, as reported by Mobile Syrup

One more thing, your device should not rooted prior to get this update or you will be facing update failure issues from Kies.  Kies is smarter now, it can read your device for any modification made. Anyway, the stock 4.1.2 T989DTLUMC4 is available below if you knew how to manually flash it directly to your device. You will lose root once this official firmware installed, but this version can be rooted using latest SuperSU.

Odin back to stock:

– Back up all important files before proceeding. Although the Internal memory and microSD card are both left alone during after the flash process for this firmware is a non wipe version. But all your settings and configuration will all be reset. So, be sure to have a back up all of it for safety.
– If your device currently runs with any custom ROM, you may ask any assistance first from your ROM developer on how to safely return back to official stock to get rid of any issues. Mostly, you need to back-up your current ROM via custom recovery CWM or TWRP, then perform “Wipe Data/Dalvik cache” before proceeding.
