If you followed the easy install guide then you want to follow this this post

Please see THIS THREAD before doing this procedure, you might be able to avoid using the HTC unlock.

WARNING: This procedure applies to flyers (not View) only and should be used only if you get the following message when trying to downgrade:

"Main Version is older! Update Fail! Press <POWER> to reboot"

If you upgraded to HoneyComb using the Official OTA perform these steps, otherwise skip to section "Downgrade" below

Perform a HTC unlock using the HTC unlock website

Download this recovery download MD5: bb366b025dcc454ffe8b21b8bf0c72d0

Download superuser from here

Copy the su zip file to the root of your external SD card.

Boot the flyer to fastboot mode

Flash recover

Code:

fastboot flash recovery recovery.img

Reboot to recovery and install the su zip file.

Reboot to android

Proceed with the downgradre procedure below.

Downgrade

First download the RUU for your device from this thread.

If there is no RUU for your region/operator, download one of the unbranded ones and create a goldcard

If you don't know which RUU to use see post #2.

Download misc_version_universal.zip and extract the misc_version file from it.

If you don't have adb and fastboot on your PC

Get fastboot and adb tool for windows here

Get Fastboot and adb for linux here

check the version number for your RUU
In my example I am using this RUU: RUU_Flyer_HTC_WWE_2.00.405.3_R_Radio_20.3501.30.08 9BU_3809.05.04.10_M_release_194964_signed.exe
The version is the part highlighted in red.

Boot your flyer up to android if it's not already on, with usb debugging enabled and connect it to the PC.

Run the following command:

Code:

adb push misc_version /data/local/misc_version

Run the following commands:

Code:

adb shell $ su (make sure your screen is unlocked so you see a toaster notification if it appears) # chmod 777 /data/local/misc_version # /data/local/misc_version -s [COLOR="Red"]2.00.405.3[/COLOR]

Note that the number in RED is the version number retrieved in step 4.
You will see a message about backing up and writing misc partition

Reboot to fastboot:

Code:

adb reboot bootloader

[*]Relock the bootloader:

Code:

fastboot oem lock

Run your RUU

If you have correctly completed the process you will no longer get the "Main Version is older! Update Fail! Press <POWER> to reboot" message and you will be able to downgrade to GingerBread.

Note: By choosing an appropriate value for the version it is also possible to return to a specific operator ROM if you have previously upgraded with a goldcard and you have a suitable original RUU. If using the procedure for a downgrade within gingerbread you must first root the flyer and skip step 8. For example you can downgrade from a WWE RUU to an O2 RUU.

Please edit your post and remove the quotation of the entire first post, it traps information that might be out of date in the future in the thread.

I am still getting stuck somewhere with the downgrade from HC to GB. I am S-off with revolutionary recovery.
I followed post 3 in the Easy Install post as mentioned here
I copied my GB RUU into the fastboot directory and got to this

fastboot erase cache
fastboot oem rebootRUU

but after 12 minutes of it sitting in the black screen with the HTC on it, and no progress bar, I tried the flash PG41IMG-WIFI.zip command. and that gave me an error of unknown partition, cannot determine image filename. Do I need to rename that as well to PG41IMG.ZIP to make that work?

Also do I need to copy in the full name of my RUU or rename it in my fastboot folder to RUU.exe? I didn't know if that oem rebootRUU command would just do the RUU in the folder regardless of the name.

Thanks!
(trying not to crap out my flyer!)

globatron · Feb 19, 2012

run the commands *excatly* as written with *exactly* the files specified. You can't do a pick and mix from different procedures.

You're not even in the right thread if you're posting in this one.

glparke · Feb 19, 2012

First line of this thread takes me to post 3 of your easy install HC method which is what I followed to try and downgrade again. Probably should have posted this question there?
I copied and pasted the commands into my command prompt with my GB Ruu and that wifi zip file in my fastboot folder.
How long does our take to run that Ruu before I need to run the Ruu.

Thanks

There is no waiting between commands, when you can run a command at the command line you do. The error about the partition you saw was becasue you didn't enter the command correctly.

thegoofyweirdo · Feb 22, 2012

Worked Great!!!!!!!!!!! Thank you guys for all your help and write ups!!!

But i cannot make recovery backups because the bootloader is now locked again correct?

I did downgrade without locking my bootloader... I'ts booting now... for 5 mins... still the HTC logo? I'm stuck. How do i lock the bootloader? In adb it says device not found

EDIT: I think i can solve it now... i hope so. Awww didnt fix it

You can only boot to fastboot mode until you have run the RUU to complete the S-ON procedure.

Boot to fastboot mode and then run the appropriate RUU and you should be good.

Boot the phone to fastboot mode
Run the following command:
Code:
```
fastboot getvar cid
```

This will return the CID of your device. Find the appropriate RUU from this list:
The Xs that appear indicate that these numbers are not important for RUU selection, only the numbers which are not Xs are important.

Don't kick yourself...

Open a dos window, go to the directory where you unzipped fastboot & adb files, and run this at the dos prompt.

Has anyone got a mirror for RUU_Flyer_HTC_WWE_1.36.405.4. The File factory link is a joke.

ruffneckZeVo · Apr 14, 2012

I have the same issue than in post 211 so will try with fastboot but I have an intermediate problem: it looks like the flyer is not charging anymore (orange light blinking) and altouhg I could go in bootloader or fastboot mode, I cannot anymore.
Any idea?

Thanks

I'm afraid I have to join the recent chorus of those in need of help.

I followed the instructions in "Downgrade" of Post #1. (It seemed to be the right one as I looked at the options.)

After the RUU installation, my Flyer (US Best Buy WiFi model) is stuck at the white screen with HTC. I shut it off, boot into hboot, and all the options but Fastboot take me back to the white screen with HTC. I ran the RUU a second time, and still no dice.

I used the Brightstar 2.27.1540.31 RUU. I've poked around and hoped to be able to figure this out, but alas, I cannot.

My ultimate goal is to install this: http://xdaforums.com/showthread.php?p=25247476#post25247476 but I need back to GB from HC first.

Thanks, folks! Any and all help is much appreciated.

Jeff
