[EVO 4G Android Development] Team Scream:
Ok I had this EXACT same problem with my first EVO which lasted me 9 months and MULTIPLE roms.

I was on HW003 and had gone MONTHS primarily using Fresh EVO.

In fact Fresh was the ROM I flashed when I rooted my first EVO.

I originally rooted using Toasts method back in Jun of 2010 (yes I got one of the first EVO's out).

Then I wanted to try the MIUI rom.

So, because it was newer, I installed RA 2.3 and I am absolutely convinced that THAT is when all of my problems started.

MIUI (while a completely *****en concept) gave me a LOT of problems which I am not convinced I would have had, if I would have stayed with RA 1.8.

None the less, I ended up flashing back to Fresh 3.5.0.1, then to MiKFroyo 4.5.

After that, I started having issues with MiK, rebooting, FC's, general sluggishness when I could actually get the phone to stay alive for an hour at a time. Fresh was my go to rom so I knew if I went back to it, I should be able to get a good handle on these problems and I would be fine.

Not so much......

The phone started boot looping, freezing, FC'ng on apps that NEVER gave me a problem in the past, and put me through the most frustrating part of being on a rooted phone I have ever experienced.

I then un-rooted, and stayed on a stock rom for a day with few issues.

So I decided to try and root again using the method described on the first page of this thread.

Initially, I only got part of the way through the process, but ended up with a new rom on the phone by default as I booted into the rom that comes packaged with this process (the AutoRoot 2.3 package).

However, when I tried to go back and flash Fresh 3.5.0.1, I quickly became aware that I did not have a recovery package installed.

Then, in a panic, I went through the un-rooting process all over again by removing the SD card and installing the PC36IMG.zip file to the SD card, and got back to stock but NOT stable.

I still had the same rebooting issues and was ready to throw the phone against the wall.

Ultimately I tried as many things as I could to get rooted properly. New batteries, new SD cards (3 of them) etc, and nothing allowed my phone to stay active for more than just making phone calls. It was a mess.

Today, after the 10th time un-rooting and going back to stock, I threw in the towel and brought my phone to the Sprint store and got a replacement.

NOW, I decided to root the new phone.

So, I went back to try this AutoRoot 2.3 method AFTER disabling my firewall, and virus protection to make sure that NOTHING would interfere with the process AFTER rebooting my computer.

Moral of the story is I got the SAME exact errors you did and here is what I did to fix it.

Once I got to the point that you did, my phone actually rebooted to the included rom, but when I rebooted the phone manually (power/vol down) and tried to get into recovery, I noticed S-On, so I knew there was no recovery, but I tried to get into recovery anyway and got the red triangle.

So I double clicked the startrecovery.bat file and it loaded the RA 1.8 mod file that is included, but at the bottom of the screen it indicated "undefined" or something like that in the build #. and VIOLA I was in recovery.

At that point I flashed the S-Off.zip in hopes that it would unlock the phone, and after a reboot IT IN FACT DID EXACTLY THAT. Anyway, so I knew that I would be able to flash a zip file if I could get back to this point again.

After I tried to boot into recovery, I discovered that it did NOT install RA and I was back at the red triangle.

I pulled the battery, and rebooted into bootloader and did the HBootUSB thing, and got my SD card mounted to my desktop.

I then copied over RA 1.8 as a PC36IMG.zip file, and then hit the power button to get out of USB mode. I then repeated the steps to get me back to the red triangle, and launched StartRecovery.bat again and got back into recovery.

At that point, I flashed the PC36IMG.zip (AmonRA 1.8) and went through the motions and was rewarded with a good install of AmonRA 1.8 .

From there, I flashed all of the NV, PRI, Radio and WIMAX files one at a time.

(rebooting between each one to properly install each individual file), and then flashed MiK 4.5.

I am happy to report that I am currently enjoying MiK and will know shortly if I have been successful or not.

So far things look great. Sorry for the long post, but from memory, those are the things I had to do to get rooted, and get a good rom installed.

It was a pain in the ass and definitely not automatic.

That being said, THANK YOU to the OP for putting this Auto Root set up together. I am sure it took a LOT of your time to do, but on 2 separate phones, it did not work for me, yet the tools included in the package enabled me to get there in a round about way.
