[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

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] 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..

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:
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

[Q] downgrade problem

I tried to root my Desire Z running Andorid 2.2.1 by following guide on Cyanogen wiki.
Since my software version is 1.82.405.1 I had to downgrade it first. I gained temporary root but when I reboot to bootloader and try to flash PC10IMG.zip it start loading but It fails when cheking file. I'm sure I downloaded it correctly because I checked md5. What am I doing wrong, or have I missed something?

Try fastboot, very easy (just rename the file,look at the wiki)! It's really easy, I downgraded and rooted in about one hour.

I also have problems with downgrading. I'm currently using stock 2.3.4 on my G2. When I try to downgrade it to 1.19.531.1 using the guide from CyanogenMod Wiki I face a problem. When I insert this line "/data/local/tmp/fre3vo -debug -start FAA90000 -end FFFFFFFF" into cmd it says: "/data/local/tmp/fre3vo: not found"
How can I fix this?

...follow this guide (temp root & downgrade):
http://forum.xda-developers.com/showthread.php?t=1178912
...for perm root use the wiki:
http://forum.xda-developers.com/wik...sion#Rooting_the_Vision_.28G2.2FDZ.29_and_DHD
EDIT: @kepos: you may need a goldcard / @Isstatu1: you first need to push fre3vo to data/... and then chmod 777 it...

I push the fre3vo and it shows a lot of text in cmd. then I write "adb shell", everything works, the $ sign appear, then I write the "chmod 777 /data/local/tmp/fre3vo" part, it says: "Usage: chmod <MODE><FILE>". After that i write "/data/local/tmp/fre3vo -debug -start FAA90000 -end FFFFFFFF" and it says that fre3vo is not found..

If you type adb devices, your device is listed?
What does it show if you push fre3vo? ...because as far as i remember it should only show you how long it took to push

Yes it shows my device.
Now, when I type "> adb shell cat /dev/msm_rotator"
it shows
/dev/msm_rotator: not found"
Nvm the underline part, it works now. But still having problems with fre3vo..
Can I PM you?

Be warned that this has been reported to cause bootloops on Sense ROMs, proceed at your own risk.
A few disclaimers before I begin:
1) I AM NOT RESPONSIBLE FOR ANYTHING YOU DO TO YOUR PHONE. ANYTHING YOU ATTEMPT TO DO YOU DO AT YOUR OWN RISK
2) This method requires use of adb and is not for thr faint of heart. your phone WILL be bootlooping along the way; this is exactly what we want (at a specific point)
Now to begin in earnest
First find what we need!
We need the patched misc version, tacoroot, and the earlier GB RUU
Modified htc drivers or linux, both with working adb installation
disable fastboot on your device

adb push tacoroot.sh /data/local/
adb shell chmod 755 /data/local/tacoroot.sh
adb shell /data/local/tacoroot.sh
At this point we will run tacoroot with the --recovery, (push volume up and power at the triangle) (reboot after this) --setup and --root (run one, wait for the device to settle then run the next)
AT THIS POINT YOUR DEVICEWILL BE BOOTLOOPING; THAT IS PERFECTLY NORMAL
Now we downgrade the misc_version
adb push misc_version /data/local
adb shell chmod 777 /data/local/misc_version
adb shell /data/local/sh -c '/data/local/tmp/misc_version -s 2.18.605.3'

I'm just a little unclear about what comes before and after this...
Can we get a post that has ALL the code/instructions spelled out? For instance, the "Preform manual tacoroot exploit"... is that the tacoroot code from before in its entirety, or just a certain part of it?
And then when the instructions in this post are done, are we to then follow the downgrade instructions from beginning to end?
Sorry to be pesty, but really want this to work and I'm just unsure of what all to do. Many many super thanks.

After you do this, use an RUU to downgrade and then use revolutionary to obtain s-off. I'll look into the tacoroot in a minute, like I said these aren't my instructions.
Edit: Nothing like a quick google search to make you feel like an idiot lol. The adb commands are the manual tacoroot exploit. I'll update the OP to make it more clear.

OP updated. Make sure to post and tell me if this works.

Thanks, but still unclear about one thing. To flash the RUU, do we follow all the instructions in the downgrade vivow .98 thread?

You have to combine all the instructions.
If you go to the rootzwiki page I spelled it out. Just can't link to external sites because I'm new to xda.

Perfect. Thanks and can't wait to give this a try in the morning.
Do you (or anyone) think it will matter that I have already (successfully) used the HTCDev boot unlocker?

It took some tinkering (and a bit of sweating), but I was able to get this to work successfully.
I had previously used the HTCdev tool to unlock and was running clockwork recovery. I had to flash the stock recovery and do a factory restore, but still got a "99 unknown fail" when trying to flash the RUU at the end of this process.
A quick google search told me to relock the bootloader with "fastboot oem lock." After the relock, I had to do ANOTHER factory restore and then everything worked fine.
One difference for me: the bootloop started earlier, ie after "adb shell /data/local/tacoroot.sh --root". But I just continued to use adb when I could and got through it.
About to run Revolutionary. Thanks to everyone up to this point! Such a fantastic community!

not to rain on your parade but this makes no sense. after the adb reboot recovery..... i do the adb shell and then it cant find the file/directory

Are you rebooting out of the recovery? You do "adb reboot recovery," and then when you get to the red triangle, hold down volume up AND volume down and then the power button, reboot, let the phone reboot back into normal, and then continue the instructions.

unstuck! ... then stuck again

Is it significant that, after the sym-linking of /data/local.prop to the log file and then rebooting, my phone had no signal and seemed pretty inoperable, but then after the write to /data/local.prop failed (and I sat googling around for a bit) the phone rebooted itself (no adb commands, and I didn't even breath in its direction) and came back to having signal and my settings, etc. and full operability?
Any help appreciated - I'll come back to this tomorrow ...

Thanks a lot, quick question though, will this send my phone into a continuous bootloop if I don't run aosp?

Trying this now. Hopefully it fixes the
Code:
cannot create /data/local.prop: permission denied
errors other people and myself are seeing.

worked until i ran the tacoroot.sh --root command. Didn't root my phone and left me hanging at
Code:
adb shell chmod 777 /data/local/misc_version
adb shell /data/local/sh -c '/data/local/tmp/misc_version -s 2.18.605.3'
after --root this is what i received.
Code:
Usage:

--setup : Setup the phone for root, must be done before --root.
--root : Root the phone.
--undo : Remove TacoRoot.

Rebooting into root.

Interesting. Looking over the code and tacoroot.sh, nothing actually puts the misc_version where it needs to be lol. Updated the instructions and added "adb push misc_version /data/local" before "adb shell chmod...", try that.

yeah i was just going to say looks like a the push misc_version was missing which solved everything for me.
as for others with this problem if the push misc_version doesn't seem to help i'd take a loot at this post here http://forum.xda-developers.com/showthread.php?t=1526316 for manually changing the version.

So it worked?

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'

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
$ chmod 777/data/local/tmp/fre3vo
chmod 777/data/local/tmp/fre3vo
Usage: chmod <MODE> <FILE>
$ /data/local/tmp/fre3vo -debug -start FAA90000 -end FFFFFFFF
/data/local/tmp/fre3vo -debug -start FAA90000 -end FFFFFFFF
/data/local/tmp/fre3vo: permission denied
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
