Actually following suggestion here

http://xdaforums.com/showpost.php?p=18335570&postcount=243

I was able to flash using the RUU instead or pushing to the sd card.

Maybe this would be good to add to the guide in post 1?

Yup, that's the one I used.

[G2 and Desire Z General] SynisterWolf:
i just want to say. i helped my brother do this to his g2 but it was 2.3.4 and it sill worked.

this was a great guide. it sucks that its the old way with ADB push and what not but this should be stickyed so the info doesnt get lost.
[G2 and Desire Z General] sibble-comp:
Hmm, eyeballs are starting to glaze over.....

I've got at least a dozen browser tabs open with XDA Forum posts (plus google searches), many with contradictory info :-(

I have 2 goals

1) upgrade this Bell Desire Z downgraded to 1.34.666.1 rom back to 2.3.3 stock

2) same as above but rooted

suggestions on the best thread to accomplish #1

reading through this

http://xdaforums.com/wiki/index.php?title=HTC_Vision

What's mostly confusing me is where to get the 2.3.3 upgrade..

contrary to some comments I've seen, there doesn't appear to be an available stock and rooted 2.3.3 for the Bell DZ.

I just also wanted to confirm, using this guide on a T-Mobile G2 with update 2.3.4 and I was able to downgrade without any issues. :D
[G2 and Desire Z General] abprie:
thanks, the guide worked for me on a german DZ 2.3.4 stock. (now i can root... :) )
[G2 and Desire Z General] sibble-comp:
Hmm, well, I'd already downgraded the phone to 1.34.666.1, so followed along here

http://xdaforums.com/showthread.php?t=1055581

and got root, s-off, then flashed this RUU

to debrand the phone. Of course it looks nice, but now I've lost root, reading the forums and google, doesn't seem to be much in the way of a 2.3.3 with root available for flashing for the DZ from what I can see. I'm reading up on the rom you mentioned now.

Ideally I'd like to match what I've got on my G2 with the official OTA 2.3.4 ASOP since it seems a lot faster (and cleaner) that the DZ 2.3.3 rom. Then I'd wipe and reload an unrooted 2.3.4 on the G2.

I'm not averse to being rootless, however it would be handy to be able to do nandroid backups and such.
[G2 and Desire Z General] :
Worked for me!!
[G2 and Desire Z General] sibble-comp:
Colour me impressed. Yes it's fast, but still slower than an ASOP. I've generally not been a big fan of HTC Sense type stuff going back to my Windows Mobile days, however overall I am liking this InsertCoin_Vision Sense2.1 + 3.0 (v1.6.1) rom you recommended.

[G2 and Desire Z General] r2d-two:
I am stuck at the fastboot-linux step...

After issuing the reboot command through adb, the phone reboots into the white screen with the menus, and it says in blue "HBOOT USB PLUG".

Now I try to use the fastboot-linux utility, but the utility does not seem to recognize my MT4G:

[linux]$ ./fastboot-linux devices

????????????	fastboot

@OP: Could you please re-post the manual method of performing whatever the "fastboot" utility is doing? I followed that manual method a month ago on another MT4G phone and it worked fine.

Thanks!
[G2 and Desire Z General] r2d-two:
Never mind. I figured it out.

FWIW: if the fastboot utility does not work for you, just place the old ROM (the one that you are downgrading-to) in the SDCARD and name it: PD15IMG.zip. Then, issue the adb reboot bootloader command. When the white screen menu comes up, select BOOTLOADER by pressing the power button (or it may do this by itself, which is ok too), and watch it load the PD15IMG.zip file, then check it, and finally ask you if you want to "upgrade" your phone... Answer Yes and that's it.
[G2 and Desire Z General] Setherio:
I am so glad I decided to save a backup before I updated the guide. I will add that section back as soon as I can figure out where I put the backup... o.O;
[G2 and Desire Z General] haasor22:
Here is how I got past this:

1: unplug phone phone from computer.

2: hard reboot (remove battery then power back up)

3: Factory restore on phone in recovery

4: Another hard reboot

5: run all SDK updates

6: plug phone in to PC and start whole process over paying attention to copy the FILES not FOLDERS to platform-tools directory

Hope that helps some one else out there.

I have the same request as r2d-two, could you repost the manual method? I downgraded using it and it worked fine. I understand you have to find the original post first, so it's worth the wait. Thanks for writing the guide.

Corrupt download, check the md5 of the rom.

[G2 and Desire Z General] cwburns32:
I'm pretty tech savvy but I'm unfamiliar with them term "md5". A quick explanation is all I need. And where to download a new zip?
[G2 and Desire Z General] Nipqer:
an md5sum is a checksum, a 128bit alpha-numeric string, which is unique to every file.

Just redownload from the first post, just under the download links is a md5sum for each of the files.

You can check the md5sum with many free programs, I like LiLi's MD5 Easy Hasher

Yeah md5 is wrong, redownloading now. I dled on my laptop then transferred via hard drive, therein lies the problem.

My pastebin:

http://pastebin.com/9mjeQ7Yn
[G2 and Desire Z General] Nipqer:
yeah that error pops up from time to time, seems to have something to do with /system being a little corrupted.

How long have you had the phone? How many apps have you installed?

could be easier to help you if you came onto the irc channel. #G2ROOT on freenode

-Nipqer
[G2 and Desire Z General] cwburns32:
Phone is a little less than a year old, many apps on the phone, I try to load freenode and I just get a blank white page.
[G2 and Desire Z General] Nipqer:
Weird, webchat is working good for me.

Yeah the /system partition is probably a little corrupted, thats why busybox won't work.

Although busybox shouldn't be essential for root, so you could try run a backup app anyway.

[G2 and Desire Z General] cwburns32:
I got her rooted, s-offed, etc, etc. Thanks Nipqer for quick replies, I'll check freenode again.

For your cwm issue, don't use power to select stuff, use trackpad or camera button.

It doesn't matter whether the sim card is in or not.

[G2 and Desire Z General] dirtyreturn:
I used the manual method about a day or two ago, hit adb reboot bootloader and everything worked fine. I need to do it again. So, I get to adb reboot bootloader, should'nt I get kicked out of adb shell or does typing exit solve that problem?
[G2 and Desire Z General] Nipqer:
You'll only get kicked out of adb shell if you run an exploit, or stop the connection to the phone somehow.

Typing 'exit' (or hitting ctrl + c) will stop adb shell, so that you can then run adb commands.

[G2 and Desire Z General] Shambolicuk:
Getting a little worried :S im on stage 9 0r the downgrading section, my laptop has been sending the zip files for about 15 mins now is this normal mates? The phone screen is showing a black screen with the grey htc logo in the middle and my cmd prompt is flashing dending files.

Edit, its still in process :( dont want to pull the lead or battery but surely it shouldnt take this long?
[G2 and Desire Z General] blahbl4hblah:
Do you have adb setup? And in the pathway depending if your on Linux or windows?
[G2 and Desire Z General] Shambolicuk:
Yes mate i set the sdk and adb via the cyanogenmod wiki then followed this guide, everything has gone exactly as described in the original post, but for some reason i appear to be stuck at the "sending zip" part. I have a uk desire z and i downloaded the correct rom from the original post.
[G2 and Desire Z General] blahbl4hblah:
That's strange actually. Adb never fails me most of the time but if the files are sending the next best option is to mount your sdcard and then copy the files to the root of your sdcard and use root explorer or another root accessing file manager to copy the files into place and then do the next procedure. The rom shouldn't take more than a few minutes actually 5 minutes max I think depending on the speed of your computer and the sdcard class
[G2 and Desire Z General] Shambolicuk:
Im actually on a fairly low powered (1.6 gig dual core) which i got for messing around with stuff on and had no probs in the past. I have no idea how to mount the sd card now as i cant use my phones interface. If i pull the lead am i bricked?
[G2 and Desire Z General] blahbl4hblah:
What exactly is step 9? I never used this before so yeah but idyllic all your doing is pushing the files to either data or sdcard then it shouldn't do anything.
[G2 and Desire Z General] Shambolicuk:
In command prompt step 9 was teliing windows-fastboot to install StockRom.zip As there is no progress indicator in the cmd prompt its hard to say if its actually doing it or if its failed. I checked the process in my windows 7 task manager and its not really using any cpu power. Ill have no option to turn it off soon as i have to go up the missus house :S
[G2 and Desire Z General] blahbl4hblah:
Oh then I don't know sorry though
[G2 and Desire Z General] Shambolicuk:
No probs mate, thanks for assisting :) I closed the command prompt and disconnected the lead, pulled battery, turned everything back on and im not bricked at least :) Ill try again tomorrow with the manual install method of the ziped rom.
[G2 and Desire Z General] blahbl4hblah:
Just let me know if anthing just message me if anything

That's basically it haha

adb shell via terminal then do the commands

Hey nipper, that makes a lot more sense, its confusing enough as it is, but that seems quite logical :)
