[Q] Downgrading bell dz 1.84.666.2 - G2 and Desire Z Q&A, Help & Troubleshooting

hey guys i was looking around and all this information is scattered into multiple threads and such. So i was wondering could anyone give me step by step instruction like get x file and follow y steps(even is said steps are from another post) because I am completely lost looking through 5 threads back and forth.
So far i followed the instructions of this guide(just got root): http://forum.xda-developers.com/showthread.php?t=905261
instead of using his RUU and PC10IMG i am using the one from this link: http://forum.xda-developers.com/showthread.php?t=815253
so if i extract the rom.zip from this file change its name to PC10IMG.zip and place it on the root of my sd card i don't need the gold card and can coninue normally with that guys guide?
Help would be appreciated.
also i will still be able to get back to stock even if i do this correct?
or how would i go about downgrading with AMT someone said that worked for them

Woops i figured it out sorry AMT is really easy i think i was misreading the instructions the first time...
If anyone else is wondering this get AMT 1.81 (or whatever there is) get the RUU from my first post. Extract the rom.zip explained later on in the other guide i linked in my second post.
Place the rom.zip (rename to PC10IMG.zip) in the root of you sd card. Run AMT and use its downgrading feature. Reboot into boot loader, and update.
This is for other newbie like myself who are having trouble downgrading their bell desire z. Obviously your doing it at your own risk and if anything goes wrong im not the person to go to.
How this helps some newbies out there.... i feel stupid for having so much trouble with this oh well better safe then sorry

HTC Desire first time flash new user

Hi this is my first post so go easy on me please, Im looking into flashing my htc desire im fairly familer with flashing other devices such as xbox or ps
and i want to ensure i get this right obviously. Xda is a great source of information .. ive tryed to read through a lot of it to make sure im familer with proccess
and id just like to make sure ive understand what has been posted correctly.
So as far as rooting is concerned i can follow either of these 2 guides :-
h**p://rootmydroid.co.uk/guides/desire/howto-root-your-htc-desire
h**p://forum.xda-developers.com/showthread.php?t=696189
•Root guide for users who have unbranded(unlocked) Desire - post #2
on this guide i notice you flash with rootupdate.zip , so am i correct in thinking that with any of the roms i download i just rename them to rootupdate for this proccess to work ?
Also ive noticed a lot of talk about backing up and one program keeps popping up called nandroid , as far as im aware i can use this to make a image of my phone and restore at a later date should i want to,
is there a tutorial ive missed in regards to this program someone could point out or any other programs i should use to backup data on phone ... ?
Finally my phone details , i would just like to confirm that im fine for flashing
FW version 2.1update 1
baseband version 32.36.00.28U_4.06.02_2
kernal version 2.6.29-0cb9f166

software number 1.21.405.2
H.Boot 0.80.0000
Microp-031d
Radio-4.06.00.02_2
Any help is obviously appreciated thank you , as i say i want to make sure i understand the tuts and info provided
nooooo no no no no, first of all follow this guide to rooting its by far the easyist, http://nimbu.amorvi.com/2010/05/how-to-root-your-htc-desire/, once rooted you will be able to flash any rom from recovery, i suggest flashin the latest clockworkmod recovery from here http://www.unrevoked.com/#desire, when flashing anything there is no need to change there name these days
Just follow the following tutorials to root and flash roms. It's easy as pie.
http://theunlockr.com/2010/06/07/how-to-root-the-htc-desire/
http://theunlockr.com/2010/06/07/how-to-load-a-custom-rom-on-the-htc-desire/
For backup, recovery and whatnot, use ROM Manager app from within Android. It does the same thing as nandroid in recovery mode.
wow thanks for the speedy replys guys really appreciated , im going to go over the information both of you have provided over tea shortly and post back
Since you are 0.80 i suggest not to follow the nimbu's guide. These guides from my understanding is for Hboot 0.75 and lower. The higher ones like myself use a different file. You can follow the steps from theunlockr.com but don't use their file. If u want the 0.80 file i would get it from desire.modaco.com its i think on the first page of the forums.
I just flashed yesterday and i had to open many different tabs cause none of the guides state 0.80 or higher and which files to use.
ok ive gone thru the tuts both have provided and i notice they all tell you to make a gold card , i was under impression i dident need to do this as my phone is network free ?
why not just use unrevoked 3.0?
well this tut i posted is revoked
h**p://rootmydroid.co.uk/guides/desire/howto-root-your-htc-desire
also can i confirm i dont need to make a gold card as im unbranded / network free ?
My phone was unbranded but I still couldn't get past step II on Unrevoke, which was related with goldcard. I suggest you go make one.

Rooting problem, please help

Hi first post
I've been rooting my desire today using the forum guide and may have run into a problem. I thought I better ask questions before I make matters worse.
I ran into a problem when I couldn't get the r5-desire-root-alt zip file to download, so I googled htc desire root in hope of finding it elsewhere, which I thought I did. I had in fact found r6-desire-root-alt and set about using the guide on this forum with the above file.
I've ran into a problem when I get to "In the command prompt/terminal window, enter either 'step2-windows.bat', './step2-mac.sh' or './step2-linux.sh' as appropriate." as the step 2 bat file doesn't exist in r6.
I've since been able to download the r5 file and I'm hoping that I can use the step2 bat from that but think it would be wise to ask people a bit more savvy when it comes to doing this.
The guide I found with the r6 file is on modaco. My other option is to follow the latter stages of that guide but I haven't copied the update zip to my sd card, which is now in my desire and in recovery mode. I didn't want to disconnect, turn off and do this in case I made matters worse.
All help & advice appreciated.
If it helps at all my software is version 1.19.161.5 (Vodafone UK) and the bootloader is 0.80.0000
Can you boot into your normal ROM or have you kept it in recovery???
If you can you should use the one click root method by Unrevoked you can use this to root your HTC desire on one click

I've left my phone as is in recovery mode. I didn't want to do anything that might cause problems.

Desire working again...Maximum Respect to Droidzone

You may have seen a few of my posts on here over the past couple of months about the trouble I've had with my Desire freezing up.
Well, maximum repsect to Droidzone. Following his instructions I've managed to get my Desire working again...it's not back to T-Mobile UK stock yet, but rather it is now HTC stock (2.2) - but still sim locked to T-Mobile.
Still got a couple of more things to do to get it back to stock T-Mobile UK (I've only done step 1 and 2 of Droidzone's guide), but going to keep testing it for a while first.
For anyone else on a rooted T-Mobile UK Desire with custom ROM then I would recommend Droidzone's guide....simple and easy to follow (if you have problems, I'm happy to talk you through how I managed it). The only major problem I had was keeping my Desire from freezing long enough to create the goldcard and install the HTC stock ROM. Since I got that far though, I haven't had any problems.
Here's Droidzone's guide....

@Eddy,
Since he has AMOLED, there's a multistep procedure he can try.
1. Prepare the goldcard correctly with a Format in Fat32 (and deleting any extra partitions. Only 1 partition should exist-It should be a Fat32 Primary). If Goldcard is correct, phone should not give CID incorrect error.
2. Download the WWE 2.29 PB99IMG.zip, and put it in the goldcard and run it.
3. Run Teppic74's downgrader with goldcard. At the last step, choose to use this PB99img (Run this RUU while monitoring your Temp folder for changes. When the RUU loads and displays a window, search temp for Rom.zip. Rename it to PB99IMG.zip and put it in the root of the sdcard) instead of the Teppic one.
4. At this point the phone will have a completely working 2.1 Android OS branded to TMO.
5. Check for and update with OTA (You will get TMO OTAs at this point). Now your phone will have the latest TMO ssoftware and be as good as any other!

[Q] Downgrade from 1.84.666.2

I stupidly updated my Bell Desire Z to 1.84.666.2 the other day. Looking for a way to downgrade to a version that can be rooted.
Found this thread, but it's for a previous update.
http://forum.xda-developers.com/showthread.php?t=905261
Love this phone but I really want to dump Bell's extra software and Sense.
Please, any helpful input is appreciated!
How far through that guide did you get, what error message? I did 1.84 -> 1.34 to get S-OFF & root.
Following the tutorial got me temp root access but was unable to boot the firmware. I suppose I need to make a goldcard but that tutorial has a few broken links. Anyone want to give me a resource that explains what is going on in that tutorial a little more deeply? I remember reading in a previous forum that 1.8 update could be rolled back.
I'm on a Bell DZ too...

You will need a goldcard if you don't already have SuperCID via gfree, and you can't find an earlier ROM/RUU that matches your CID.
Sent from my HTC Vision using XDA Premium App
I'm getting stuck at step 11. I get to the white bootloader screen and without doing anything the phone does and SD check, looks for PC10DIAG.zip, etc, then finds PC10IMG.zip and checks it. Then I get bumped out to the bootloader list of FASTBOOT, RECOVERY, FACTORY RESET, SIMLOCK and IMAGE CRC.
It's unclear what to do from there. The tutorial says I'll get a prompt to update and restart, but I don't.
Also, the tutorial says I'll need a goldcard (which I created) but no where in the tutorial does it say what to do with it...
I got a goldcard using Gold Card Tool. Just do a google search of "easy goldcard".
I've managed to iron out that issue. I had made a mistake when making the goldcard.
Problem now is that when I get to step 11 the phone says "Model ID incorrect!" then "Update Fail!".
Any ideas?
Where are you getting your PC10IMG from?
From the guide I linked earlier. (http://forum.xda-developers.com/showthread.php?t=905261)
I downloaded the full RUU and renamed the extracted rom.zip.
I had goldcard issues (broken links) so I got the rom that matched my current region. I then did the temp root, modded the version info and let the phone try the update. Once I got it all sorted it worked as is said in the guide. I don't know if the goldcard tool worked or not, I think not as I wanted to change the Asian phone to WWE but had to go down to Asian 1.34 then go S-OFF and then go WWE. Maybe an extra step but it worked.
How do I find a rom that matches my current region?
The desire z was purchased from Bell Mobility in Canada and is now being used on Rogers.
This thread may be of help to you: http://forum.xda-developers.com/showthread.php?t=1029821
Thanks for that link! I basically did as the guy said and used the link to the 1.34.666.1 rom you linked in that thread. Only difference was I uploaded it to the SD and the issued the command adb reboot bootloader. This time no errors and the update worked!
So now I guess I just go ahead with a normal root of a 1.34.666.1 DZ?
Weird thing is the guy in that other thread said he got S-Off from doing this update... On my phone it's still S-On.
All you have done is put a rom on the phone that allows S-OFF, I can't see anyway you could get it in a stock rom?!

You should now be able to follow this guide to get S-OFF (as above, I don't see how flashing a stock ROM would do this automatically): http://forum.xda-developers.com/wiki/index.php?title=HTC_Vision
So after downgrading I had S-ON. But I just finished the rest of the rooting process in the guide I linked in my original post and got root!
What a process. That must have taken 12 hours or more. I should really post a new guide with more complete info.
Thanks for the help guys!
Now that I have root and S-Off downgrading from 1.84.666.2 to 1.34.666.1 using the processes DVDWSN did. Now I thought I could go back to 1.84.666.2 using OTA like I upgraded the first time. But when I try to do OTA, I get the message I do not have any new version. What gives?
If you are trying to downgrade do not touch OTA updates lol. Anyways, what you want to do is temp root your phone so you can 'spoof' the radio version the an old one thereby allowing you to flash a radio that can be manipulated. If you aren't sure what to do then try following this guide.

Downgrading my Z

My desire Z is currently running android 2.2.1.
The downgrade tutorials i have found are from 1.74 to 1.34.
How do i get my phone to 1.74 so i can downgrade to 1.34?
Thanks
which version number are you currently running.
2.2.1 is the android version(a version of froyo)
the 1.74.xxx is the firmware number made by HTC and some may be 2.2.1 and have 1.74.xxx or like me have 1.84.xxx
since you are 2.2.1 you will most likely have to downgrade to a 1.34.xx rom
depending on your carrier you will need a RUU from them, example i have a bell Desire z so i would need a bell RUU. This can be found in one of the stickies near the end, i think its the sticky for roms and everything under development.
Extract the rom.zip from it as stated in the 1.74 to 1.34 downgrade guide. rename to "PC10IMG.zip" place this on the root of your sd card.
Get AMT(advance multi tools) [REMEMBER TO THANKS HIM HE IS AWESOME FOR MAKING THIS APP ] from the developer section and run the downgrade option. Reboot into your bootloader and apply the update voila ur downgraded now you can root or whatever you like.
WARNING: This worked for me i'm a Bell desire z user so it may differ for you and i take no responsibility if you follow this and mess up.
It worked for me so it may work for you if anyone sees a problem with this people speak up.

How do i check which firmware i am running?

Under settings> about phone is software information or something of the sort it will say 1.34.xxx, 1.74.xxx, or 1.84.xxx that is the firmware version. If its 1.34.xx you do not need to downgrade.
Also i ment 1.34.xxx RUU so you may extract the Rom.zip from it
How do i find out what my carrier is?
Your carrier is where you got your phone from such as bell, or t-mobile(G2), or other DZ sellers in europe (i do not know who sells them there)
if you got yours from tmobile the RUU from the guide u posted the link to is good. (follow that guides step 7 to extract the rom.zip from the RUU regardless of which RUU it is)

Did you rename the rom.zip file to PC10IMG.zip, is it already a zip file and you added .zip with the .zip extension automatically hidden by your computer (some computers automatically hide file extensions so really your files name is "PC10IMG.zip.zip" in which case delete the .zip you added. Is your CID one of the ones in that thread at the beginning if not its easier to follow the guide i posted above. Finally is the PC10IMG.zip file on the root directory of your sd card.

In my software info, this is exactly what it says:
Android Version
2.2.1
...
Build Number
1.72.405.2.......
Software Number
1.72.405.2
I bought the phone from ebay, and the seller said it was from carphone warehouse...so what carrier would that be?
My CID is one of the ones listed.
i put the PC10IMG.zip in the home directory of the sd card. should i have put it in one of the folders? if my phone is not the tmobile one, should i find a different file? (RUU?) ie..the file PC10IMG.zip that i have is incorrect?
thanks a lot mate. the problem was the .zip.zip thing. im so annoyed. ive been stuck all weekend lol. thanks
^ lol ya i have seen that happen to alooooot of my friends that is why i have been starting to recommend people checking that out XD i really dislike it when windows tries making things more user friendly but takes away vital information for users who know what they are doing.... they should have a better setup asking what you want hidden and such ughhh.....
What about if the software number is 1.82.xxx.x?
Can I still use the following guide?
http://forum.xda-developers.com/showthread.php?t=905261
I tried before but it failed not sure if I did anything wrong or the method is just not compatible for my version.
Can anyone advise me on this?

you just have to download the original Image from the thread insted of using your own.
and you have to check that you got no error when typing /data/local/tmp/misc_version -s 1.33.405.5
i did the tut again and it worked for me ;D
