[T-Mobile myTouch 4G Slide] Mortico:
I think I've made a few mistakes but I don't think all hope is lost. Part of my problem is simply that most of the links to ROMs and images for this phone are broken.

I'm going to try to keep this as short as possible, but this is what I did...

I followed this guide: http://xdaforums.com/showthread.php?t=1801106

Unlocked bootloader with HTC's tool.

Flashed CWM recovery

Backed up stock ROM (1.55.531.3) with CWM

Flashed MikTouch 0.7 ROM

On reboot, the screen hung on the mytouch logo, so I presume that the flash failed and restore.

A few more tries and I decide to root and S-OFF before trying to flash the ROM again.

Used a superuser apk to gain root, verified that root was obtained.

Loaded up an ubuntu live CD, ran JuopunutBear.

Followed all steps and did the wire trick wrong (only tapped once instead of twice).

It failed, on rebooting the phone the following screen is displayed: https://www.dropbox.com/s/d1hz7j66h7mxj36/2014-10-13 13.46.31.jpg?dl=0

On checking the SD card, I find that the phone is unable to mount it, it seems to be fried so the backup I had is now gone.

I attempted to do the wire trick (correctly) many more times with no success.

I was able to revive the SD card later by repartitioning it with the MT4GS and then formatting it with my HTC Amaze, but the backup is still gone.

Did a ton more research and then went to bed...

This morning I woke up and shut off the computer I had used to do JuopunutBear, thereby losing the backup that it had made (mistake, didn't realize there was a backup there).

The only stock ROM I could find with a working download link was 1.28.531.9, I renamed it to P59IMG.zip and tried to flash it.

No luck, it has a progress bar that fills, then it reboots and I'm back to the screen with the green arrow.

I tried relocking the bootloader first, and it seems to get further but then fails when it realizes my HBOOT is newer than the one in the image.

I've been looking into downgrading the HBOOT version to 1.44.0007 so I can just do an S-OFF and be done with it, but I can't figure out how to do that.

I hear that you can't get S-OFF with 1.45.0013 using JuopunutBear, of course I only found this out today but I'm not even sure it's true.

The guide I was following uses HBOOT 1.45.0013 so when I get to the step where it says I can flash ROMs, I'm not really sure why it didn't work for me.

So here's where I'm stuck...

HBOOT 1.45.0013

S-ON

Unlocked

CWM 5.5.0.4 Recovery

Stuck on the software download screen: https://www.dropbox.com/s/d1hz7j66h7mxj36/2014-10-13 13.46.31.jpg?dl=0

I've gone through this process with several phones so I'm not really new at this. I've done a Samsung Behold II, HTC myTouch 3g and an HTC Amaze 4g. At this point I think my best course would be to restore this phone to stock before trying anything else. If I had a signed 1.55.531.3 ROM then I think I could get it back to where I started so I can try the whole thing again. But I can't find a working download link to one. I'd also be fine with going back to 1.28.531.9 as I think I could more easily do S-OFF with it.

Can someone with a bit more knowledge/experience please let me know if I'm missing something? Or just post some links to the ROMs I need?

Thanks!
