[Q] Problems downgrading/rooting Desire Z Gingerbread. - G2 and Desire Z Q&A, Help & Troubleshooting

Hello everyone!
Not my phone, just helping a friend
We got problems downgrading from Gingerbread to earlier version of Android.
So, wanted to root, flash custom recovery, then MIUI.
Started with this tut, then understood, that Gingerbread isn't rootable and it needs to be downgraded.
So, tried [GUIDE] Downgrade G2 (2.3.X) & DZ (2.3.X) & mT4g (2.3.4) & DHD w/ S-ON to Stock Froyo and HTC Desire Z: Firmware Downgrade (Gingerbread).
So, installed JRE, JDK, SDK (ADB), drivers.
With phone plugged to PC (USB Debuggind ON), ADB & Device manager sees it.
So, moved files to C:\android-sdk\platform-tools and ran cmd (administrator privileges). Till "adb shell it's good". But, after that, when ran chmod, it says, that permissions denied.
Question:
What we're doing wrong and how to fix it?
We've read so many guides, but unsuccessfully so far..
Device HTC Desire Z

Thanks about helping!

Is it permission denied when u try to change the version? If permission denied during change the version, run this command:
cd /data/local/tmp/misc_version
chmod 777 misc_version
./misc_version -s 1.00.000.0
sync

Are you sure your temp root is working?

aDeQ666, no, it wont chmod when typing chmod 777 /data/local/tmp/fre3vo, so - no temp root for us. Tried visionary, z4root, SuperOneClick - nothing works
It was updated from Froyo to Gingerbread via OTA, i think that's the issue? What else we can do? Thanks!

Could you post a copy/pastebin of your cmd when running it? It'll be much easier to spot the error if we can see exactly what you did/are doing.

I have one problem when i tried to root htc desire. i already done the downgrade and now i am want to root... i folllowed the instructions on the link you gave untill this
[chmod 755 /data/local/tmp/*
/data/local/tmp/psneuter
NOTE: You will drop out of the shell after this command. Restart the shell using:
adb shell
cd /data/local/tmp
./busybox md5sum /dev/block/mmcblk0p18]
well after command:
chmod 755 /data/local/tmp/*
/data/local/tmp/psneuter
i`m not dropping out of the shell and the next instruction results with a "cd: bad substitution" msg. what should i do?
sorry for my bad english

When do u received the error? Is it when u downgrading or try to root? Are u using the wiki guide?

What I've down a few times now (and this does work) is use the fre3vo guide (the one you linked) to downgrade then continue with the guide below from step 14 or 15 to gain perm root.
http://forum.xda-developers.com/showthread.php?t=905261
Hope that helps.
Edit: You're better off flashing 1.34.405.5 as the one on the CM wiki may not be working. Its worth a shot IMO.

Hi, i have been trying to change my misc version but it gives me permission denied and i have # (root) already. So i tried chmod after cd which didn't have a problem but now when i try harder./misc_version it says the file not found.
Please help

I used this guide. it worked fine for me =)
http://forum.xda-developers.com/showthread.php?t=905261
*faceslapps self* sorry. I was a tad too fast. I didn't see that someone allready posted that guide here.

This is the command that i use before this:
adb push misc_version /data/local/tmp/misc_version
cd /data/local/tmp/misc_version
chmod 777 misc_version
./misc_version -s 1.00.000.0

I used this guide when I had to go through the pain of downgrading my desire z http://forum.xda-developers.com/showthread.php?p=15851843 . It worked very easily, just follow the instructions nice and carefully, the problem is that you need ADB set up for you to use that guide though.
Once you downgrade though, I would use the guide here for rooting your phone http://forum.xda-developers.com/wiki/index.php?title=HTC_Vision#Rooting_the_G2 .
I hope that helps, that's what I used for my phone.
To be more precise in regards to the problem though, i just realised that i had the same problem as you when i was trying to run the chmod command where i had temproot but i kept getting "permission denied". As it turned out, i had accidentally written "adb push fre3vo /data/local/tmp/" instead of "adb push fre3vo /data/local/tmp" when i was following that downgrading guide. Basically what my mistake did was, it pushed fre3vo into a new folder within /tmp instead of just placing fre3vo in /tmp. So what you can do to figure out where fre3vo is, navigate to the /tmp folder using CD (in adb shell) and once you get to /tmp, type "ls". This will then display all the contents of /tmp and then you will be able to see if you accidentally created a folder like i did. Then once you check that, when you go to run the chmod command, you have to run it like "chmod 777 /data/local/tmp/**possible accidental folder name**/fre3vo", see if that works now .

Use this guide should do the job for you www.desirez.strawmetal.com

were you able to fix this problem?

I had the same problem with my Desire Z with OTA 2.3.3.
Finally I've unlocked bootloader as show at htcdev.com.
Then I used this guide http://forum.xda-developers.com/showthread.php?t=1453066 (great thx for it), and CM 7.1 works like a charm.
All best.

[Q] Turning S-on help

I am trying to unroot my g2 in order to send it in. I used gfree method on Wiki to root the phone and to unroot it. However, I am stuck trying to turn s-on. When I enter:
$ adb shell /data/local/tmp/psneuter
I am getting:
/data/local/tmp/psneuter: permission denied
Any ideas?
I believe you have to do "chmod 755 /data/local/tmp/psneuter" on it (I'm not -too- sure on the numbers, but I think it's 755)
EDIT: chmod 777, my bad - thanks posters below
Well the steps from the wiki are:
$ adb push psneuter /data/local/tmp/psneuter
$ adb shell chmod 777 /data/local/tmp/psneuter
$ adb shell /data/local/tmp/psneuter
$ adb shell
It's the 3rd one that I am stuck on.
Since I am unable to get temp root following the wiki, would I be able to use visionary to get temp root and then s-on following the wiki?

Hi !
Are you sure that you got a valid copy of psneuter?
Try to download the zip from psneuter.zip unpack it and try it again with the file that is called psneuter in it.
have fun - Guhl
Thanks for the help! Unfortunately that didn't work either. Not sure whats going on, but I think it's something with the phone. I just cannot figure it out. At least it works for now.
Type:
1)adb shell
***you should see the '$' symbol (if you have '#', then do nothing, you're already root)
2)chmod 777 /data/local/tmp/psneuter
3)/data/local/tmp/psneuter
4)exit
5)adb shell
6)su
If you have the '#', then you're root
I don't know if this will work, but this is not dangerous at all to try

Thanks you for trying to help! When I got to the third step it told me permission denied again.
I was able to FINALLY get s-on. I thought I would post how I did just in case anyone else ends up having this problem.
I used visionary to temp root my phone and then used the wiki to turn s-on. Only problem I had was trying to remove the psneuter file from the phone. Other than that no problems. Now I shall see if I can get away with sending the phone in.

[Q] Permroot on Desire Z failed - what I do wrong?

Hello.
I've tried to root my Desire Z. I wanted to achieve only the ROOT not S-off and so on. Just to be able to use some root requiring applications like DSP Manager or Adds free.
1. So I've downloaded and installed Android SDK.
2. Started ADB
3. "adb devices" gave me the proper answer
4. Then I've copied and started psneuter and misc_vesion:
adb push psneuter /data/local/tmp
adb push misc_version /data/local/tmp
adb shell chmod 777 /data/local/tmp/psneuter
adb shell chmod 777 /data/local/tmp/misc_version
adb shell /data/local/tmp/psneuter
adb shell
/data/local/tmp/misc_version -s 1.33.405.5
exit
5. Then I've tried to root the phone:
Ive copied the required files:
adb install AndroidTerm.apk
adb push busybox /data/local/tmp/
adb push gfree /data/local/tmp/
adb push rage /data/local/tmp
adb push root /data/local/tmp/
adb shell chmod 0755 /data/local/tmp/*
adb push su /sdcard/
adb push Superuser.apk /sdcard/
And then from the Terminal Emulator I've entered
/data/local/tmp/root
I've got some messages that the everything is read only so I've tried rage first:
/data/local/tmp/rage
I've got the proper "Forked #### childs" output
and then I've tried the "/data/local/tmp/root" again. But I'm getting the "cannot fork" message.
I'm new in this stuff s please help me. What do I do wrong?
I only want the simple root access I don't want to downgrade my phone and install any custom roms.
Please help.
ps. my "compilation number" is: 1.72.405
As far as I remember your supposed to flash 1.34 Rom after changing the version number to 1.33 as the rooting is only possible via 1.34 Rom and not 1.72 Rom .... And you clearly missed that step .... Open desire z wiki and read the psneuter guide ... Follow it word for word .... You will root your phone

Just out of curiosity, if you only want to root to use some applications and such, why don't you just temp root using visionary and just redo it whenever you restart your phone?
Thanks for the answers guys.
your supposed to flash 1.34 Rom after changing the version number to 1.33

hispeedworm - I don't want to downgrade my phone. I don't need it and I don't want to loose whole the settings and apps and start from the beginning just for using some special apps.
mmduluth - I've used the visionary method from this topic while it seemed the easiest one for the beginner. However after taping the "TempRoot Now!" the VISIONary+ seemed to hang. The screen was black for several minutes.
So I've decided it does not work.
Anyway, I'd prefer to have permanent root than a temp one for example for using "autostarts" - which as far as I'm concerned works AFTER rebooting the phone.
So anyone could tell me where is a mistake in what I did?
I suppose I've omitted one thing in former trials so I've tried to root it again.
After entering the Terminal Emulator I've run rage:
/data/local/tmp/rage
I've got the Forked #### childs message so everything was ok till then.
Then I've reset terminal --> menu-->reset term
And then I've run the terminal again.
I should get the # sign but what I get is the totally white screen with no possibility to write any command. It's not responding. I can only get out from it by pressing the home button.
So what's going wrong?

If you read enough threads/post, at the moment, the only way to gain permaroot is to downgrade your ROM. Unless, somebody finds a way to do it without the need to downgrade.
And, as I understand, using Visionary apps would cause damage to your device. Be careful!

Thank you silverwind. Now it's clear.
So anyone is working on this?

[Q] Temp Root and Downgrade issues 2.3.3

Hi Guys.
I have watched your Noob video and it's very funny.
However,I am going to have to risk being a "noob" due to the fact that im unable to post in the dev thread for downgrading.
I have decided to root my DHD and everyone says this is the place to go to learn how to do it.
I have read the instructions throughly and decided to take the plunge, however I'm having some problems
with the method described in the first post!
Please let me tell you what I have done so far.
1) I have read the posts at http://forum.xda-developers.com/showthread.php?t=879525 (doesn't seem to apply to me.)
2) I am running Build version 2.50.405.2 (So I need to downgrade.)
3) I have the latest version of HTC Sync installed.
4) I have created a gold card as directed in the "How to downgrade" post and also placed PD98IMG.zip in the root of the gold card
inserted in the phone.
5) My DHD is running Gingerbread 2.3.3, Software number 2.50.405.2 so I followed section b2 of the downgrade thread
http://forum.xda-developers.com/showthread.php?t=905003
However at the end of the cmd process I see a "$" symbol, not the "#" as per the screenshot.
Any ideas anyone?
Cheers.
Greg.
Update: I just tried the method here
http://forum.xda-developers.com/showthread.php?t=1152233
for "TEMP-ROOT ANY Gingerbread build and downgrade to 1.32.405.6"
I manage to temproot using the alternative method of typing the adb commands under the Temp Root heading.
I finally get the "#"
I still have the gold card with PD98IMG.zip in the DHD.
I go to Downgrade step 4 and again use the alternative method and type in the commands only for cmd to say
"adb: not found"
AAAGGGGHHHHHHH!
I have been trying this all day.
I'm going to curl up in a corner and cry now.
Any help greatly appreciated.
Greg.

Hey dude.
Tried this, didn't work.
I successfully manage to get temproot using the code you gave, but then on reboot the below happens.
Always, when I get to the boot loader it recognises PD98IMG.zip and looks like it's loading it. After loading it I get a "Checking PD98IMG.zip" message then the bootloader just returns to the main screen, I am never asked if I want to update!
Getting totally flumoxed with this! :-(
So I have made a youtube video of the problem.

You can't just flash PD98IMG.zip when this is an older base then your current.
When your phone is finished checking, it decide not to flash it cause it's older.
Apologies, I should have said I manage to get temproot using the code supplied. I have updated the post now.

I wonder if my PD98IMG.zip file is corrupt.
I just did an MD5 check but it's tough to tell as the original PD98IMG.zip file I downloaded from here didn't have an MD5 Checksum with it
Hi guys.
Quick update. I have successfully downgraded my DHD.
The issue was a corrupt PD98IMG.zip
I downloaded MD5 Check 2.1 from here and tested the checksum of the PD98IMG.zip against the MD5 Checksup posted at the top of the page here, post 261,
Quick Ref - (C3D244A9F056E48EE3851A14FF52204C)
When MD5 Check 2.1 showed it as not matching, I downloaded a new PD98IMG.zip from here.
I used MD5 Check 2.1 to the checksum this new PD98IMG.zip. Success, it matched.
I transferred the new PD98IMG.zip to the goldcard I made using these instructions (I don't know if I actually needed a goldcard).
I put the Goldcard in my DHD, used cmd to run the below code as given by rohithksaj, thanks bud, which echoed the instructions here.
Code:
adb push fre3vo /data/local/tmp
adb push misc_version /data/local/tmp
adb shell chmod 777 /data/local/tmp/fre3vo
adb shell chmod 777 /data/local/tmp/misc_version
adb shell /data/local/tmp/fre3vo -debug -start F0000000 -end FFFFFFFF
adb shell
after this # type:
/data/local/tmp/misc_version -s 1.31.405.3
exit
adb reboot bootloader
When the DHD rebooted into bootloader, I selected "bootloader", then waited about 5 seconds for the bootloader to recognise the PD98IMG.zip.
the DHD then goes through a process of loading the PD98IMG.zip then it checks the PD98IMG.zip.
Finally the screen that eluded me appeared, the "Do you wish to start update?" screen.
I chose yes, 5 mins later I had a downgraded phone.
Thank you all for your help on this issue.
Props to you all.
Greg.
My next question is how do I change the thread title to "XXXX -Solved"?

[Q] Desire Z with 2.42.405.2 Able to downgrade? ( i'm able to temproot )

Hi all
I have a European HTC Desire Z with this info:
Android 2.3.3
Sense 2.1
Build 2.42.495.2
Vision PVT Ship S-ON
Hboot-0.85.0013
MicroP-0425
Radio 26.10.04.03_M
eMMC-boot
Apr 11 2011,23:36:27
I am able to temproot this phone with the method provided here:
http://forum.xda-developers.com/showpost.php?p=15851661&postcount=1
using the code:
Code:
$ /data/local/tmp/fre3vo -debug -start FAA90000 -end FFFFFFFF
However the downgrading part fails on me.
After entering the bootloader menu is scans the SDCARD and finds the PC10IMG.zip
telling me: loading...[PC10IMG.zip], after that it's saying: Checking..[PC10IMG.zip].
After checking it just goes back to the Menu without asking me to update etc.
I did however changed the misc_version and followed the guide precisely.
I searched and found some Threads saying this version isn't rootable yet. though they were couple months old, and I am able to get temp root. it should be do-able right?
Can someone please confirm this and tell me how to, or what i'm doing wrong and let this baby free.
I followed the guide to the letter, without changing misc_version or anything, and I managed to downgrade and root without problems on first try. Same version as you, Desire Z bought in Poland.
Just be sure to grab the file for Desire Z and not for T-Mobile G2 and it should work

What file are you referring to here?
Also, how is it possible to downgrade without changing the misc_version, i thought it was all about changing that in order to make it work haha.
Sorry, I think I misunderstood your post...
I did this to change misc_version:
Code:
$ adb push misc_version /data/local/tmp/misc_version
$ adb shell chmod 777 /data/local/tmp/misc_version
$ adb shell
# /data/local/tmp/misc_version -s 1.00.000.0
I assumed you changed the "1.00.000.0" to something else (while browsing the forum I found in some threads that people used a different value on DZ).
As for the file I was referring to, I meant the stock rom image - 1.34.405.5_PC10IMG.zip
Maybe you grabbed the file "PC10IMG_Vision_TMOUS_1.19.531.1_Radio_12.21.60.09 b_26.02.01.15_M2_release_149459_signed.zip", which is for G2?
Other than that, I'm not familiar enough with the bootloader to be of any help.

I redownloaded the zip file and you just made my day i had a other zip from another thread. but with the exact same name.. maybe corrupted ? THANKS!
Radio's get flashed AFTER you flash your ROM, not before ;P
Remember to rename your PC10IMG.zip to something else after you're done rooting/installing a new ROM, cos if anything happens and your phone crashes and you need to enter recovery, having PC10IMG.zip on the root of your SD will ensure that you never get into recovery
Power + Vol Down boots into bootloader, and it automatically scans for updates, PC10IMG.zip being one of them. Only when there are no update files on SD root will it give you a choice of booting into Recovery to well, recover your phone

[Q] gfree -y: unknown operation... why?

Hi,
I had to return to stock rom for warranty and now i am trying to root it again. i have completed root and s-off operations but i can't enter recovery. when i select recovery from bootloader menu, i only see exclamation mark with black screen...
i entered these commands but second command gave me "gfree -y: unknown operation". how can i solve this?
Code:
4.a.2. gfree, install hboot and clockworkmod recovery
In the root shell (indicated by the #) that you got in the Temporary root section execute the following commands:
# cd /data/local/tmp
[B][U]# ./gfree -f -b hboot-eng.img -y recovery.img[/U][/B]
# ./root_psn
# sync
Means you are running an older version of gfree.
Only gfree 0.7 supports the -y arg.
You can find it here
(to find out what version of gfree you have, use ./gfree -v )

Thank you for your help but now the same command is giving me "./gfree: permission denied". why should it be?
Did you use the chmod command? Check the wiki, but it will probably be something like "chmod 755 /path/to/gfree"
chmod 755 /data/local/tmp/*
Also the command might have to be:
/data/local/tmp/gfree -v
to run gfree, unless you cd to /data/local/tmp (or wherever you pushed gfree to), in which case the '.' in './gfree' means 'this directory'

Thank you all for help. Everyday i had another error. For example today i got psneuter error but i finally installed recovery...
