Got an 'E: failed to mount /efs (invalid argument)' and did not previously backup EFS. Sending my phone to Tmobile, how can I reset counter if I'm stuck in a boot loop?

Is there a way to side load triangle away? or an ADB command?

I can get into recovery and download mode.

Any and all help will be appreciated.

How did you get to this point? Did you have a custom recovery running, if so which one? ROM? Did you try to revert from 4.3 to 4.1 via Odin? Have you done a wipe? What steps have you taken so far? Something as simple as kies emergency recover could get you back.

You may be able to recover.

I got into this I believe by accidentally wiping 'system' via TWRP. I was wiping the phone to trade, and believe I wiped more than I should have. I have flashed back to TMO_T889UVUCMK7 stock via Odin, same boot loop.

I tried the Kies Emergency Initiasin and it goes through successfully. Then I boot into stock recovery, wipe cache and wipe data, and it will boot back into a boot loop.

I would even consider flashing a Pit File at this point.

Which TWRP version were you using? I had a problem on an early version of TWRP 2.7 not playing nice with 4.1.2 and corrupted a partition in a way that looked very much like the way you describe. I got back by doing 2x factory resets, and Odining Mr Robinson's root66 ROM twice. I was on the latest 4.1.2 bootloader so I just flashed the UVALJ1 version and it came back. If you have the Knox bootloader you are stuck with UVCMK7 as your only option.

Once I did that I was able to boot up and get back to where I wanted to be.
