How to install I727RUXUMA7 via Odin flashing


Disclaimer: This guide is for advance users only, if this your first time heard about this method, make a careful research first before proceeding. We shall not be held responsible if anything happens to your device by using this guide. Proceed at your own risk!

Step 1: Grab the relevant files for flashing I727RUXUMA7
- Odin3_v3.07 Flasher tool Odin3_v3.07 link
- Samsung Galaxy S2 USB driverDownload link
- Original I727RUXUMA7 Stock ROM
Canada  – I727RUXUMA7_I727ROYAMA71_RWC.zip  download link

The Stock ROM can be used and only compatible on Canadian SGH-I727R (Rogers)  and U.S SGH-I727 (AT&T). Do not ever play with it on other Galaxy S2 variants.

Step 2: Extract or unzip the downloaded stock firmware so that you’ll get the Odin flashable .tar.md5 file. Use Winzip, winrar, 7zip or any extracting tool you had in your computer.
Step 3: Run and Configure Odin
Run Odin downloader on your computer’s desktop. Watch out the check-boxes options on the right top of Odin, ensure that the ‘RE-PARTITION’ is unchecked. Leave the ‘AUTO-REBOOT and ‘F.RESET TIME’  remains checked.
Now, click on the PDA button, then select and load the tar file that you have previously extracted

Step 4: Reboot the Galaxy S2 into Download Mode.
To put your galaxy S2 in download mode, just simply switch it off, then -
SGH-I727R Rogers- Press and keep down only the Volume Down key.
SGH-I727 AT&T  - Press and keep down both Volume Up and Volume Down keys simultaneously.
A warning screen appears to continue (volume up) or cancel (volume down) into download mode.

Step 5: Connect the Phone to the Computer or Laptop
Once the phone screen shows in downloading mode, connect your phone to the PC with the USB cable. You’ll then notice the upper box in Odin that turns in yellow color., it also indicates the COM:ID where the device is being detected and a word “added!!’ on the log box. If somehow those things never showed up, check out the USB cable connection, read again from the top of this post.
Step 6: Flash it!
Once all set and ready, hit he “START” button to begin flashing.
Do not touch anything that might interrupt the process to avoid any fatal errors or failures, it may ruin your device if any interruption occurs while already in flashing status.

It may only takes about 3 to 5 minutes, depends of your PC/laptop speeds. A word “PASS” will display in Odin once it finishes. If somehow you will not get the word “PASS” or just stuck in along time. Disconnect the phone, remove battery, re-insert it, check the USB connection, re-install the driver, disable Kies and any anti-virus. Set the phone in Download mode again, and repeat the whole procedure.

The phone will just automatically reboots if the firmware flashing successfully completes. Just wait until it boots up on the “S” logo for a while then into an android update screen. If it still shows boot logo try rebooting and if it stays there, you need to wipe your phone.

Fixing possible issues after flashing like bootloops or just stuck on welcome screen logo


Boot in recovery mode –
- Press and hold Volume Keys and Power button.
- When it vibrates release the power button. When the displays goes blank release the Volume keys
- Use volume keys to select up and down and power or home key to select the option.

1. Select Wipe Data/Factory Reset
2. Next select the Wipe Cache Partition
3. Lastly select Reboot System Now to reboot your Galaxy S2 in Normal mode.
Confirm your fresh firmware installed.
Go to Settings>About>Firmware info.

  10. ML - I get about 6M speed now when tested with speed test app. My biggest issue is that the earpiece volume is low and cannot hear well. Oh well... hope they have the S4 soon and I will probably upgrade.

  11. Humph, all went well, but AT&T is reporting me as "out of the service area" and my About Device is now reporting it as a Rogers phone (SGH-I727R NDROIS 4.1.2 I727UCLI3 Kernel 3.031-885181 se.infra@SEP-127 #1 SMP PREEMPT Wed Jan 30 20:06:41 KST 2013) with Build# JZO54K.I727RUXUMA7.

    I have WiFi only, no voice or 4G/LTE data.

    I got as far as a ring tone when dialing 611 to ask AT&T to "register" my IMEI again but then they auto-hung up on me with the "out of service area"

  12. OK, so let me as it another way; has anyone taken an AT&T Skyrocket, flashed it with the above and actually made it work (with JellyBean, 4G/LTE and all the bells and whistles) on AT&T’s network?

    Since downflashing mine back to the the stock ROM, I’m still stuck on Gingerbread; it won't do an OTA upgrade to ICS and my mail app keeps crashing…. I’ll be travelling next week and really hoping I can get my poor phone back to full functionality, but until someone here confirms that these steps (followed exactly) will really work as planned on an AT&T device, I’d be cautious about proceeding

  13. Hi There,
    Updated to 4.1.2 on Rogers Galaxy S2 LTE however it does not show LTE sign any more most goes to 4G, I am told that this Rogers problem rather than the phones, and I saw a Fido today with same 4.1.2 update and it does show LTE sign as mine was showing 4 G. Anyone know about this problem? Speed test is lot lower than it used to be on 4G and sometimes I see H+, I dont know what is this, any idea and input about this problems?

    ReplyDelete
  14. It also happens like the U.S releases, it's about the firmware builds.

    ReplyDelete
  15. I installed this update and now my phone is almost always on 2G, not 4G or LTE like it was before. Does anyone know what I can do?

    ReplyDelete
  16. I upgraded two phones with the update and I find it has slowed the phones and it appears to to cause freeze ups, swipe and auto correct don't work as well and the text messaging emoticons have gone backwards in my opinion...is there an easy way to go back to the original firmware?

  17. Rogers fix lte network sick of this 4g H+
