[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.

Hi Greg, try this method, http://forum.xda-developers.com/showthread.php?t=952352

I hope I could help you, best regards, gluecke63

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.
Cheers.

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] Problems downgrading/rooting Desire Z Gingerbread.

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..

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 =)

*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:

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

I had the same problem with my Desire Z with OTA 2.3.3.
Finally I've unlocked bootloader as show at htcdev.com.

Problems downgrading/rooting - fre3vo not being found?

I'm trying to root my Bell HTC Desire Z and I'm getting stuck pretty early just trying to downgrade to Froyo.
No matter what guide I've followed this is far as I'll get typing in the terminal:
adb push fre3vo /data/local/tmp
adb push misc_version /data/local/tmp
adb shell
chmod 777 /data/local/tmp/fre3vo
I'll then get a response saying unable to chmod /data/local/tmp/fre3vo: no such file or directory.
I've placed the fre3vo file in the same folder as adb so I'm super confused.
Any help would be super appreciated!

edit you first post and change the title of the post... it will change the title of the thread's name too

Now, I'm making even less progress.
adb push fre3vo /data/local/tmp
turns back with:
cannot stat 'fre3vo': No such file or directory

That error means fre3vo is not in the directory cmd/terminal is pointed at.
You need to either use the 'cd' command (change dir) or, if you're on windows, you can hold shift and right click in the dir fre3vo is, and select 'open cmd here'
-Nipqer

Alright, so I'm having slightly more luck following this guide http://forum.xda-developers.com/showthread.php?t=1178912&highlight=root+bell+desire+z
I've got to the portion about "Changing Version Number to Allow Downgrade and Gaining SuperCID with a Goldcard" but when I type:
# cd /data/local/tmp
I get cd /data/local/tmp: not found
I thought I was making progress...
EDIT: Never mind - I just decided to re-type the command in and it worked...moving on to downgrading

Success! Rooted my phone and flashed CM 7.2. Big thanks to Nipqer on #G2Root!!!!
Mods this thread could probably be deleted.

I am stuck on the same spot the OP was. I have done as nipqer suggested and opened a cmd window directly in the platform-tools folder and now the response coming back is
Code:
C:\platform-tools>adb shell

suggestions ?
I have read a lot of threads and tutorials on this and honestly there's so many it has become confusing. Help a fella out! :good:

follow this guide first
http://wiki.cyanogenmod.com/wiki/TMobile_G2:_Firmware_Downgrade_(Gingerbread)
now go to this guide when complete
http://wiki.cyanogenmod.com/wiki/TMobile_G2:_Rooting
dont skip steps and if you need more help log onto freenode

You ran the chmod command wrong, didn't put a space between the 777 and the /data/local/tmp/fre3vo
-Nipqer

righto, thanks guys, will take a look at the threads you linked and try again. will post back one way or the other as soon as I have something.

ok I have run into a real problem. it looks as if I have semi bricked. I skipped nothing, followed the guide to a T.
Code:
NOTE: Take note of this number, we will need it later. For the remainder of this guide, we will refer to this number md5 #3.
If md5 #1 & md5 #3 match, then gfree 0.7 failed to powercycle the eMMC chip on the device. Either the software version is too high and the device was not downgraded per the previous section, or you did something wrong. Try again or join #G2Root on Freenode for further help..
If md5 #2 & md5 #3 match, then everything should be fine and you continue on.
Code:
md5 #1 - b532ca54a073f0c4043bd7be69ebce8d
md5#2 - 2ce1bdd5e4c1119ccfcecb938710d742
md5#3 - 2ce1bdd5e4c1119ccfcecb938710d742
as you can see they match so reboot command should have been fine but all O get now is hanging at the HTC screen, unless I reboot holding the volume down button then that takes me to hboot screen. What do I do?
UPDATE - As I worked out how to use clockwork I realized I had s-off so I downloaded CM7 and followed the instructions on wiping cache and what not then installed. All seems to be working now.
Thank you.

for future reference these is very common when switching hboots (part of the rooting process) you will not be able to boot into your previous rom as partition checks will have changed. when you have completed rooting you should either boot into fastboot or recovery to flash rom of choice

[Q] Desire Z - Upgrade to Android 4

Hi Everybody,
I know, that there are a lot of threats about this fact in the forum. But nothing will work for me, aspessially important links will not work anymore. Could anybody help me?
If I go to the bootloader (noise - and Power-On) there are the following informations written:
VISION PVT SHIP S-ON
HBOOT-0.85.0013
MICROP-0425
RADIO-26.10.04.03_MeMMC-boot
Apr 11 2ß11,23:36:27
HBOOT
OK, on my cell is working a Android 2.3.3, so I have to root my cell and downgrade.
I tryed to do this with the following threat: http://forum.xda-developers.com/showthread.php?t=905261
1. I Tryed to create a GOLDCARD. I read this threat, got the CID of my cell with the the code
Code:
adb shell cat /sys/class/mmc_host/mmc2/mmc2:*/cid
. Now I should type this CID in a webformular at this link to reverse it. This formular is still working, but there is also a Excel-Tool on this page for downloading, which should do the same. So my CID like "035344534d49202010000073b900d494" was reversed to "00d400b9730000102020494d53445303".
This code I should input to this formular for creating a GOLDCARD, but it doesn't work anymore.
So I looked around and found this threat, where a goldcardcreator is downloadable.
In this zip-file is included a program named "SimpleGoldCard", which read a reversed CID from the cell. On a command-Line I typed in
Code:
gcard -c 00d400b9730000102020494d53445303 -r -o "GoldCard.img"
Than I putted in the sd-Card into the Card-Reader of my Desktop, formatted it, used the tool "HeX Editor", copyed (line) 00000000 to offset (line) 00000170 (including the 00000170 line) and pasted it to the SD-Card.
After that I hope to created a correct GoldCard.
2. After that I downloaded the files psneuter, PC10IMG.zip and root. But in this threat is written, that I have to extract "misc_version_01.zip". Where is this file? I searched in this forum and downloaded a file named like this. Are there Differences or is a special version needed? I copyed the PC10IMG.zip to the SD-Card and put this to the cell.
3. then I booted the cell again, connected it to the desktop and used the following commands to put the downloaded files to the cell
Code:
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
After that I should get the # - symbol instead of the $ - symbol which means, that I rooted the phone. But here is my first problem, I didn't get the # - symbol, so I don't have the permission to start the next programms.
4. Normally I would do next the following commands and then to reboot and flash the older Firmware.
Code:
/data/local/tmp/misc_version -s 1.33.405.5
exit
adb reboot bootloader
But when I reboot, the bootloader is looking for the PC10IMG.zip, is loading and checking this ... and gives me the information
CID incorrect!
Update Fail!
Press <POWER> to reboot.
Well, this is the next big problem.
Cold anybody tell me, where my mistakes are? I read 2 days in the forum, tryed a lot to get the final result, but now I don't have the time anymore to continue in this way.
THanks a lot. with best regards, Speedy8

Mods please move to q&a

well ... I searched again today ... and found the following threat, which was working on my cell-phone.
And also at the cyanogenmod-page you can find the relevant things to root the Desire Z. You can find it here.
Now I will first install the latest cyanogenmod, which is for the Desire Z not the Android 4, but at the moment newer than 2.3.3.
Thanks for answering, my Questions are answered.
With best regards.
