Edit* I am re-writing this post to include exactly what I did and the links to the pages where the information was found. Please forgive me if I violate any rules and or miss anything or any other thing that someone might be upset or offended by. I'm no forum pro nor am I an expert with the android os so I approached this with a lot of hesitation but it really was user friendly. Some of my steps may be unnecessary and or redundant but I wasn't sure exactly what I was doing so I did a lot to cover my bases. NONE OF THIS IS MY WORK, I simply read the instructions and guessed at the things I didn't understand. I will try to give the appropriate credit, please let me know if I forget something.

Original Instructions are on Unknownforce's thread here.
The live CD toolkit is on closeone's thread here.

PLEASE PLEASE PLEASE READ THE ORIGINAL FORUMS FOR VERY IMPORTANT INFORMATION! THIS PROCESS BRICKS YOUR PHONE (INTENTIONALLY) BUT HAS THE POTENTIAL FOR DISASTER!

And closeone for the live CD!


HERE WE GO:
I started with an HBOOT 1.5 phone (obviously), I reverted it to stock and re-locked it.
On unknownforce's thread there is a toolkit, I downloaded that and put it in a folder with adb and fastboot.
I am running windows XP so to handle the linux part I downloaded the live cd v0.2.2 (Stable Release) from closeone's thread found Here.
I used a free iso burner to burn toolkit iso to a CD, I then booted from it a couple times to make sure it was good to go and set that aside for later.
I then downloaded the 2.08 RUU ZIP image (use the 2.17 if you have updated to that) I renamed that to PG86IMG.zip and placed to the root of my SDCARD.
Next I downloaded the 1.13 RUU EXE and left that on my computer.

I then began the actual revert by changing my phones mainver per unknownforce's instructions in his thread, using zerg to obtain temp root.
After the mainver was successfully changed I moved forward with the instructions on bricking my phone (follow unknownforce's instructions VERY CAREFULLY!)

*NOTE* When I plugged AC power back in to my phone during the brick process, I DID NOT get a dim red light, I had no light at all, but I moved forward as if I did, and it was ok.

I copied the rest of the instructions from unknownforce's page to have as reference for the next part.

NEXT: BOOT INTO LIVE CD (put disc in cd-rom, turn off computer, turn on computer, allow to boot to CD)
closeone has provided a ver nice GUI with nice instructions, read and follow them very carefully.

I am not familiar with linux desktop so I had some issues getting 4 terminals pulled up and all visible at once so hopefully this might help clarify for someone. When the CD launches into linux you have a desktop folder in front of you with 2 files, one is a readme.txt THAT YOU MUST READ! and the other is a link for the terminal.
When the terminal launches there is a menubar at the top similar to windows, clicking on file (I think) I proceeded to open a "new tab" with Shell, I did that a total of 3 times (to give me 4 total terminal sessions).
I then had to go to view (I think) and select a split view which allowed all 4 to be seen. In the end the 4 terminals were stacked on top of each other seperated by a horizontal bar. Each terminal window had a tab showing which terminal it was displaying,
I made sure that each session displayed was different than the one above. Then I proceeded with the instructions found in the README.TXT

Upon completing that phase of the instructions I removed my SDCARD from my phone, re-booted into windows, plugged my phone into the USB and held vol. down + power to boot into fastboot. I then located my 1.13 RUU EXE file on my computer and ran it from windows. After that was done I booted my phone up with HBOOT 1.4!!!! Next I used revolutionary to obtain S-Off, put TWRP 2.0 recovery on, flashed superuser, made a recovery, and flashed MIUI.US!

I hope I didn't miss anything, please let me know if you need clarification on any of the steps I used.
Thanks again to all the people who worked hard on figuring this out and making it easy for noobs like me =)

welcome to hboot 1.4 i did mine the night it came out and wasnt sure if it would work...lol The thread on xda blew right up that night and WOW! it was awsome, Hey enjoy and thanks for the guide..PEACE!
 
Yeah I couldn't believe it when I read it but it was bitter sweet cause I didn't have a Linux box =/

Then the live CD got released and BAM I've got 1.4 =)

Next step is to donate cause that's what all the kool kids do!

Yea worked great for me too..dut i also never got a dim red light either..but continued on and it was bricked (:

Evo 3D ViperROM v.2.5 downgraded HBoot 1.5 to 1.4
 
I did it myself Sat night instead of going to the bar. I did have some problems, but luckliy I worked it out.

----------------------------------------------------
I started with an HBOOT 1.5 phone (obviously), I reverted it to stock and re-locked it.
------------------------------------------------------

I should have did it in this order. I relocked first then put on a stock. Ended up in HBOOT with a security flag. Couldn't do much of anything. Came mighty close to bricking it trying to figure it out. I thought. No light, no nothing.
But, the computer did seem to know it was there. after trying a few things I figured since the computer seem to sense it, I booted with the Live CD (new version 0.5.1) One terminal window one command word "downgrade" well it seemed to have worked, I got rid of the security flag in HBOOT. then put stock on it

*NOTE* When I plugged AC power back in to my phone during the brick process, I DID NOT get a dim red light, I had no light at all, but I moved forward as if I did, and it was ok.
------------------------------------------------------------

I had the same trouble with not seeing the dim LED. Most of it was my timing and execution. Too many coffees I guess lol After a few hours and many attempts. Time consuming having it reboot and popping the cover off. After all that, I just said the heck with it and did the Live CD. It worked.

I didn't remove my sdcard. Went into fast boot and ran the 1.13 ruu.exe from the windows computer. Got the HBOOT 1.14 when it was all done. Then did the revolutionary.io method. Success. Reinstalled TRWP 1.1.1,Then put CleanROM Reborn back on it and reinstalled my apps and setting. Long night for me. Mostly due to not seeing the dim LED on it.
Well all is fine now. It's working. No more 2 step process installing ROMs anymore.

Note: I wonder if I actually needed to run that Live CD a second time. Maybe just went ahaed and put the 1.13 RUU on it. I'll never know. No biggie.
 
Hey all,

I'm considering diving in a trying this. I'm never rooted before and I have a couple of questions.

Do you have the opportunity to backup the phone before it gets wiped? Is there a way to backup app data also?

I'm not aware of any app backups that don't require root, not saying it doesn't exsist just don't know of one.

The process is risky but fairly easy if you follow the steps carefully. AND well worth it!

I'm new to this. What stuff (if anything) should I stress about losing? What do you worry about losing when you wipe?

My initial thoughts:
Contacts: Backed up to googles cloud
Apps: Play Store and Amazone AppStore save all downloads. I'll have to back up apk's that I sideloaded myself
App settings and data: I guess there's no way to avoid losing this and starting from scratch?
Pictures and Video: should all be on SD card
Calendar: in the cloud
Emails: in the cloud
SMS messages: I guess there's no way to avoid losing this and starting from scratch?
Voicemails: I think these can be backed up to sd card, right? But if I flash a ROM that doesn't have Sprint's voicemail app how do I get voicemail?
Bookmarks: Is there a way to backup bookmarks? It's not many, I guess I can manaually recreate.
Call history: Is there a way to back it up? (Do I really care?)

Anything I'm forgetting?
 
use this tool it will pull all your data/apps (apk's) as far as backing up data its not recommended as it can cause issues for you down the rd

I'm on my phone so I can't see what app Benny is referring too but I assume it will perform as stated.

As for vm, you can find the evo3d sprint vm apk by googling it. I would post link if I was on pc. Additionally on every Rom I've ever used, holding down the #1 on the dialer dials my voicemail.
I would assume that there is an app to backup sms and bookmarks and others since there is an app for everything these days. BUT for all intensive purposes you will lose those should you choose to flash a custom rom, but I feel its a small sacrifice as I don't have anything important in mine.

The Play Store keeps track of your downloaded and purchased apps so its fairly easy to get back to where you were.
Outside of Android system folders the sdcard is untouched unless you manually format it. I have found that some apps and roms retain some files and settings upon reinstallation (i.e. themes for MIUI)

Hope this gives you the confidence to try, if you're successful you won't be disapointed!

What tool? I don't think you said or shared a link. Did I miss something?
 
I got all the way to the part where you brick the device..I installed ubuntu on my windows 7 so that every time i turn on the power to my laptop i have to choose to boot windows 7 or ubuntu n I could never get the live cd to boot up while i was in ubuntu. And some of the commands wasn't going thru n I knew I type them right. So 8hrs later with a bricked device I see u can even use Virtual box either while booted into windows. Phone will not power on or boot into bootloader.

i dont think you boot into ubuntu with the live cd, doesnt it run right from the cd?
but if you have ubuntu on your pc already you can do it without the cd, i know i had to sudo all the terminals when i did it,

if you here.[DOWNGRADE HBOOT/UNBRICK] HBOOT 1.50 -> 1.40 for S-OFF/Root - xda-developers
and contact unknownforce he will help you with it, he's very good guy and do all he can to help you. just PM him and he will get back to you
 
I have windows cpu tho.. n yes I somehow installed ubuntu on my cpu n have to change from ubuntu or windows 7 every time it powers on..also I got the links from the xda forums. My heart is currently hurt until I get this phone booted on cause Im already bricked. I dont know how to get my cpu to read the hboot_1.4.nb0 file. Everything else works it won't read that one file n i tried downloading others already.
 
Did everything..when i hit ./downgrade then enter I never get the message. I dont get nothing exept the thing where it lets u know u typing from the root directory
 
@LamarW89:

If your device is still bricked and you have the live CD you should still be able to recover your phone.

Don't worry about your installation of UBUNTU you don't need it, everything you need in terms of the linux portion is on Closeones Live CD.

Set your computer to boot from CD BEFORE it boots from HardDisk (done in Bios) then load the CD into your CD rom and restart your computer.

When your computer boots up it SHOULD ask you if you want to boot from the CD (maybe says something like "Press any key to boot from CD")

I have not used Closeones most recent version of the CD so I'm not sure if much has changed from when I did it but I am sure that if you download and burn the most recent one, then follow his instructions beginning after the part where you brick your phone you should be able to recover your phone and be Hboot1.4 and S-OFF!

This method seems to be fairly forgiving and many people have ran into trouble and still been able to complete the steps so don't give up just begin at the linux part using the LiveCD. And Boot from the CD not from your hard disks. If you need more specific help you can pm me a phone number that you can be reached at and I can call you and help walk you through it.
 
Also like Benny said you can go straight to the actual threads and post your problems in one of the 2 threads and somebody with some more experience could provide some more direct answers. I'm not a dev so when I run into problems I just start over (often times re-downloading all the tools as well) but so far I have bricked, broke, boot looped and everything else, my Evo3D and I'm currently running a fast smooth version of MIUI with no problems at all =)

Thanks to the dev community, this is a solid and forgiving phone to play with!
 
I had tried this on my phone, with no avail, then I had to exchange my Evo 3D because of bad charger port, with the new referb phone I thought I would give it a try and it Worked!! I love it!
