[One (M7) Original Android Development] EtherealRemnant:
********************* THIS IS ONLY FOR T-MOBILE **********************

Okay so I have been saying that I would run the downgrade, S-OFF, and report back.

Even using Windows 8, the most annoying OS in existence, I successfully now have downgraded from .11 to .8 and have S-OFF with ***UNLOCKED*** - so that method does work. And revone does not throw any errors...

Now... Here are the kickers...

It is a RUU (as I thought - HTC must have released it), it will wipe ***EVERYTHING*** so back up first. Extremely important. Don't came back here *****ing if you forget to back up - the way that the memory works there is NO WAY to recover any data at all.

If you don't have root, get Helium. Just like most ClockworkMod apps, it is worth the money. It does require you to have a Windows or Mac PC... but it doesn't just back up your apps, it backs up the data (my biggest ***** about not having TiBu access)

Now...

How do I get back the .11 rcdata and radio image? Because it was a lot more than a cosmetic change...

After that, I will pick a ROM.

Here is the key - RTFM - if you screw up, you WILL brick... Your phone will reboot to an HTC logo... and sit there for roughly 2 minutes doing nothing (count to 5 just in case), no bar will show up until the reboot... Go smoke a cigarette or drink a highball.

*******IF YOU DISCONNECT OR OTHERWISE INTERRUPT THE PROCESS, YOU WILL BRICK - I CAN NOT STRESS THIS ENOUGH - PATIENCE IS A VIRTUE THAT YOU NEED TO HAVE*******

Once it reboots, it will go back to RUU and you'll see the bar. The phone *WILL* freeze... then jump... then finish. It will reboot to a stock T-Mobile .8

From there, the easiest way to use revone is to download the toolkit (if you don't know how to find it, you really shouldn't be doing this in the first place) so that you have adb... Download revone, print out the instructions (revone is a powerful tool - the wrong commands can seriously mess up your phone), follow them - if you get any errors, reboot your computer. I didn't get any but revone does work. But if you interrupt it, your phone is a 549 USD paperweight.

That said, it went through right away... did its thing... and if you are lazy (like me), hit Ctrl C when you are in the ADB shell and type adb reboot... it takes longer to manually restart than it does to type the command - not to mention the possibility that the phone will freeze (Motochopper was never the most stable root to being with, it is called chopper for a reason)

Congratulations, you are now unlocked and you can use the toolkit to change your CID to SuperCID (11111111) and get any Android version you want from any carrier. Now here is the fun part... use the toolkit to flash TWRP. Or CWM if you are set on it but TWRP is more stable in my experience. Now you see why I HIGHLY recommend the toolkit - Just make sure you do not click anything on the left side... This unlocks your phone without HTC having you logged!

The biggest problem is that is does downgrade your radio... Now I need help getting back to where I was before or if there is a radio that tends to work better, I will totally flash another RUU. Just flashing the radio has never been acceptable with HTC... you need to flash a RUU that has everything - and once again wipe your phone.

I have been using HTC phones since my UTStarcomm PPC-6700... The biggest frustration has ALWAYS been that the radio is only part of the picture... you have to have the rest of it.

So can someone please help me with a RUU that has a radio image plus rcdata and whatever else HTC has added (my signature will tell you that I left HTC after the MT4G and "Sensation") that works well on the 1700 band? Because I backed up everything... but I don't want to restore until I'm on a radio set that works with T-Mo USA LTE again... .11 really did make a HUGE difference. And I don't feel like flashing RUUs all day. I have better things to do... but I'm going to stuck on .8 until someone helps me...

Wait a minute... now that I'm S-OFF, I can just take the OTA right? It wouldn't make sense for HTC to override S-OFF since the reason it exists is because of the constant testing releases that come out... BRB, gonna see.

Yes, it updated. I took pictures using my S3.... still waiting for them to come back to me... I had to use CameraZoom because the S3 was dead.

Basically, T-Mobile users who stupidly took the OTA can now downgrade because someone leaked a RUU.

I have given the steps.

Here is the link.

If you didn't read first and you screw up your phone, it is not on me.

And yes, I got my LTE signal strength back... Now I need to restore everything which is the biggest pain in the neck. I had S-OFFed my phone in less than 5 minutes... Since I paid for Helium, this process shouldn't take long to restore everything (although I stupidly forgot to run the save on my text messages so my porn is gone)

Anyway... Don't blow up my inbox with PMs if you screw up your phone. I highly doubt that I could be any more thorough... and if a mod feels it appropriate, please feel free to move this post to a T-Mobile specific thread because the 1.54 users are going to try this and fail...

Oh and speaking of 1.54... I ran a diff between the two and got a bunch of garbage. HTC encrypted 1.54. Not like they did with the T-Mobile 1.44 release which has no encryption... it literally spilt garbage when I diffed it.

There is a fix coming... but I ran it through every decompiler that I know - I hate to tell you... it has the same encryption as the Sensation and Desire HD/Inspire bootloader did - and I fried my Sensation with the wire trick - which will not work in this case anyway because Qualcomm fixed that flaw with the 800 chip. Hope and pray for a RUU leak... because as soon as you reset an 800 by shorting it, it does what an OMAP does... It immediately secures itself.
