Even though MetroPCS variant of Galaxy S3 is somewhat lesser known than it’s brothers, it shares the same development base (kinda).
Recently, Team Win has pushed an update for their famous and most user friendly recovery which promises to be scarce of the recovery in-compatibility issue with KitKat ROMs.
The latest version of TWRP Recovery will be fully functional with all the Android 4.4 ROMs like CyanogenMod 11, OmniRom, SLimKat, etc. They should now not give the ‘set metadata recursive’ error.
At the time of posting, the latest version of TWRP for the MetroPCS Galaxy S3 SCH-R350, is 2.6.3.0.

STEP-BY-STEP GUIDE
Once you’ve finished downloading the file given in downloads section above, follow the instructions below for installing TWRP Recovery on your MetroPCS Galaxy S3.
Important Note: Backup important files stored on internal SD card of your device, so that in case a situation arises requiring you to do a factory reset after installing the TWRP Recovery, which might delete internal sd card too, your files will remain safe on PC.
- Extract/Unzip the TWRP Recovery file, samsung-galaxy-s3-metropcs-twrp-odin.zip on your computer (using 7-zip free software, preferably). You’ll get the following files:
- Odin3 v3.09.exe
- Odin3.ini
- openrecovery-twrp-2.6.3.0-d2mtr.tar
- Disconnect the Galaxy S3 from PC if it is connected.
- Double-click the Odin3 v3.09.exe file to open Odin.
- Boot your MetroPCS Galaxy S3 into Download Mode: (The image below of Galaxy Note 2 would help)
- Power off your phone first and wait for 6-7 seconds after display is off.
- Press and hold these 3 buttons together until you see Warning! screen: Volume Down + Power + Home.
- Press Volume Up now to continue to Download Mode.
- Connect Galaxy S3 to PC. Odin window will show an Added!! message in bottom left box.
Odin’s screen would look like this:
If you don’t get the Added! message, here are some troubleshooting tips:- Make sure you have installed driver for Galaxy S3 as said above in ‘Before you begin..’ section.
- If you have already installed driver, then uninstall them and reinstall back.
- Connect using a different USB port on your PC.
- Try a different USB cable. The original cable that came with your phone should work best, if not, try any other cable that’s new and of good quality.
- Reboot phone and PC and then try again.
- Load the recovery file (extracted in Step 1) into Odin as instructed below:
- Click on the AP button on Odin and select the openrecovery-twrp-2.6.3.0-d2mtr.tar file (from step 1).
Your Odin window should look like the screenshot below:
- Click on the AP button on Odin and select the openrecovery-twrp-2.6.3.0-d2mtr.tar file (from step 1).
- Now in the Option section of Odin, make sure that Re-Partition box is unchecked. (Auto Reboot and F. Reset Time boxes remain checked, while all other boxes remain unchecked.)
- Double check the above two steps.
- Click the Start button to begin flashing TWRP Recovery on your MetroPCS Galaxy S3, and wait until you see a RESET! message in Odin’s top left box.
- When you get RESET! message, your phone will restart automatically. You can then disconnect your phone from PC.
If you see FAIL message instead of the RESET in Odin’s top left box, that a problem. Try this now: disconnect your Galaxy S3 from PC, close Odin, remove phone’s battery and put it back inside in 3-4 seconds, open Odin and then repeat from Step 3 of this guide again.
Also, If device is Stuck at setup connection or on any other process, then too, try this: disconnect your Galaxy S3 from PC, close Odin, remove phone’s battery and put it back inside in 3-4 seconds, open Odin and then repeat from Step 3 of this guide again.
