Love this phone, but I see this is the one that can't be downgraded.

The first line I got the right response but once I get to:

$ adb push fre3vo /data/local/tmp

I get permission denied.
[G2 and Desire Z General] :
Well..If you have read..Try hitting control(ctrl) C and then typing adb push fre3vo /data/local/tmp
[G2 and Desire Z General] mrchezzy:
p.s i fig it out the key to not get the error of no .zip is to push the file not drag and drop and to reboot from adb bc thats what i was doing wrong i was draging and droping the file and manually rebooting....am happy now thanks OP

[G2 and Desire Z General] Setherio:
From the pastebin link you provided, looking at the following lines...

17. C:\android-sdk-windows\tools>adb shell
18. # /data/local/tmp/misc_version -s 1.17.531.2
19. /data/local/tmp/misc_version -s 1.17.531.2
20. --set_version set. VERSION will be changed to: 1.17.531.2
21. Patching and backing up partition 17...
22. Error opening backup file.

Looks like there was a problem when you attempted to change the version number. Notice line 22, Error. Do you have your sdcard in? If not, that may be the issue. This is also why I wrote in the guide about double checking to make sure the version changed, if you look at the following lines,

25. # dd if=/dev/block/mmcblk0p17 bs=1 skip=160 count=10
26. dd if=/dev/block/mmcblk0p17 bs=1 skip=160 count=10
27. 2.19.531.110+0 records in
28. 10+0 records out
29. 10 bytes transferred in 0.003 secs (3333 bytes/sec)

Line #27 would of read "1.17.531.210+0 records in" instead of "2.19.531.110+0 records in". So for some reason the version number was definately not changed. Again, my best guess is for some reason you had your sdcard out and/or it was full and when it tried to make a backup of partition 17, it was not able to so it aborted.
[G2 and Desire Z General] Phateless:
Yup, I noticed that and wasn't sure what to make of it, so I just tried it again, this time with the sdcard in. Maybe we could add to original post that sdcard needs to be in the phone for this procedure?

You're exactly right, sdcard wasn't in and that was the problem. It's "updating" back to Froyo as we speak. ;) Thanks!
[G2 and Desire Z General] petarpLab:
EclipseX, try adb shell while you are in clockworkmod recovery and see if you have #.

if you have it, go to #g2root. someone there has an idea.
[G2 and Desire Z General] Setherio:
petarpLab is right. I just helped someone about an hour ago and we came across this problem too. So I decided to try a few "trial and error" diagnostics with him and when we entered recovery, we were surprised to see Clockwordmod Recovery there. From there, we just went ahead and installed Cyanogen and it worked perfectly.
[G2 and Desire Z General] guhl99:
You are right but that would still leave the phone S-ON.

So after you installed CM again you should probably use one of the downgrade guides (without the need to temp-root first) and then do the rooting guide at http://xdaforums.com/wiki/index.php?title=HTC_Vision#Rooting_the_G2

And i personally would do the downgrade directly before even installing cyanogen because you have a root adb shell to clockworkmod recovery.

The sequence is basically:

Boot the phone to recovery and open one terminal/command window and do:

adb shell
mount tmpfs -t tmpfs /data -o size=10m

Open a second terminal and push misc_version to the phone. get it from misc_version_02.zip, unpack it, and then:

In that 2. window do:

adb push misc_version /data/

switch back to the first terminal and do:

cd /data/
chmod 777 *
mount /sdcard
./misc_version -s 1.00.000.0

The you can reboot the phone and continue at the "Downgrading" section of the guide.

Have fun - Guhl

Hi, I've put your guide into a complete downgrading and rooting guide on an Italian forum. I'm gonna link this thread and mention it's all your work. If you don't want me to post it there in Italian, let me know.
[G2 and Desire Z General] $pitacular1:
I have tried this unsuccessfully several times. Exploit works, temp root achieved, but everytime I try to change the version I get "permission denied"

Any ideas?

I'm on linux btw.
[G2 and Desire Z General] $pitacular1:
Figured it out. This should solve the problem for anyone who faces the "permission denied" problem

When the OP said to "Download the attached files, unzip them, and place them in your platform-tools directory" he should have made it clear that it's the files INSIDE of the unzipped folders that you want.

I would unzip them on your desktop or downloads folder, then drag the FILES named "fre3vo" and "misc_version" to your platform-tools directory (do NOT drag the entire FOLDERS).

Problem is, once you push the folders instead of the files into /data/local/tmp, NOTHING will work until you delete those folders and re-push the files.

So if you made the same mistake I did and pushed the entire folders for either one of those files, make sure you wipe the /data/local/tmp folder completely by deleting all folders and files, then re-push the single files, not the folders.

After that, it will work just fine.

Hope I helped someone.
[G2 and Desire Z General] $pitacular1:
btw.. huge thanks to the OP and all sources.. this was too much fun

I think I'm going to start developing. After some intense study and research of course..

Never used ADB or SDK in my life until today.
[G2 and Desire Z General] lt1pnyklr:
When I attempt this on my MT4G, it recognizes the file through bootloader, scans everything, then says MAIN VERSION IS OLDER and it fails.
[G2 and Desire Z General] $pitacular1:
The only way that could be happening is if you skipped the initial steps and just downloaded froyo, put it in the root of your SD card and tried to do the update (downgrade) without taking the initial steps necessary to fool the system into thinking you're on an older version, or you performed those steps but did not pay attention to the results and failed.

The OP included the responses you should see to indicate success on those steps, so there should be no reason to assume they worked and try to perform the downgrade.

My guess is you never tried them and just attempted the final step, hence it failed. If you need help I'll be glad to do what I can.
[G2 and Desire Z General] Setherio:
I don't mind, but could you give me the link so I could make a section of "Translations of this Guide"?
[G2 and Desire Z General] Setherio:

As for a video, that's crossed my mind a few times, but I just don't have the time up do it.
[G2 and Desire Z General] AwesomeTurtle:
Allrighty. I have no computer of any sort at the moment, so adb is out of the question. 'cat /dev/msm_rotator' through terminal emulator gives me the good ol' permission denied, so my question is: Is adb the difference maker here?
[G2 and Desire Z General] VoiD_Dweller:
Worked great for my MT4G replacement phone this morning, took a while but it was seamless, thanks for the guide! +1 I'm currently restoring my VU 1.31 backup!
[G2 and Desire Z General] Setherio:
Yeah... too bad too because I just think I found a way to install rom without the use of a sdcard.

Filesystem Size Used Available Use% Mounted on
tmpfs 185.3M 32.0K 185.3M 0% /dev
/dev/block/mmcblk0p27
198.3M 45.3M 142.8M 24% /cache
/dev/block/mmcblk0p26
1.3G 736.1M 506.5M 59% /data
/dev/block/mmcblk0p25
409.2M 138.9M 270.3M 34% /system
/dev/block/mmcblk0p27
198.3M 45.3M 142.8M 24% /sdcard
/data/local #

Then again, I wouldn't be sure how to mount /dev/block/mmcblk0p27 (/cache) to /sdcard without being back to use adb...

So in short, I don't think there is a way...
[G2 and Desire Z General] masriprince:
i tried this so many times but always the same thing... when it goes to bootloader it doesnt downgrade or even see the PD15MIG.zip file.

I followed every step to the letter, can someone please help. im trying to downgrade a Mytouch 4g with Gingerbread 2.3.4

I cant post the link to my cmd prompt because this is my first post but i have it saved and i think ill be able to send it to who ever can help.

[G2 and Desire Z General] Flash05:
can i use the temp root method just to have really a temporary root? allows me to run autokiller, and other apps that require root?

after reboot it will go back to non-rooted stock gingerbread OTA?
[G2 and Desire Z General] Setherio:
Yes, the steps are the same. There is one exception, place a "./" before every "adb". So basically replace "adb" with "./adb" - everything else is the same process.
[G2 and Desire Z General] Setherio:
No, this is a temp-root only accessable via adb. You will not be able to access root from your phone, like in "Terminal Emulator" and the app "Superuser" will not be able to be installed correctly to grant superuser permissions to run such things like "Autokiller".

After rebooting, if you don't flash the stock rom, you will be back to non-rooted as it is a temp-root method. If you flash the stock rom, you will be reverted to whichever Stock ROM you flash, for example, if you flash the one listed in the guide, it will be non-rooted stock froyo (not gingerbread). From there, you can perm-root and flash a custom rom, including a rooted gingerbread rom.

Successful Downgrade

I just wanted to thank you for your instructions, I was quite frustrated about not being able to root my MyTouch 4G that had the OTA Gingerbread 2.3.4 on it when I bought it. This was my first time using ADB and I was able to follow your instructions, downgrade to Froyo 2.2.1, root it and install a custom ROM and I'm a gal :) I am now running Virtuous Unity 2.35.0 with Sense 3.0 and I'm LOVING it !!

does not work for G2 on 2.3.4

My G2 is updated to 2.3.4. I received the update August 30th. Build number 2.15.531.3 CL82286. This method did NOT work for me.

I got:

Potential exploit area found at address xxxxxxxx

Exploiting device...

and it kicked me out of ADB shell but the device no longer appears when I type adb devices.. rebooting the phone did not fix this. Guess we have to wait for a different exploit for 2.3.4.
[G2 and Desire Z General] lt1pnyklr:
The same thing happened to me. All you have to do now is download pdanet and let it install the HTC drivers again. Once this its complete adb will recognize your phone again and you can continue. I just ran into this about an hour ago so I know it works.

Try it, the thread title says G2 in it. For those of you where the bootloader won't pick up the file, make sure windows is displaying file extensions. If not, you might be renaming the file to pd15img.zip.zip with the second .zip being hidden.

Make sense?

Setherio,

Guhl, Nipqer and i compiled and tested a nice goldcard creation method that does not require pulling the sdcard out of the phone, is OS independent (only adb is required) and is supposed to leave the info on the sdcard intact. We need more testers at #g2root before we automate the method.

Can you please put an announcement in your guide?

Right now the http://psas.revskills.de/?q=goldcard site is down (it is needed to generate goldcard.img) but as soon as it is back up, we are ready for testing. Anyone willing to participate should check the site first, because we can not do much without it.
