do not get downgraded.

after entering the first command "adb push fre3vo /data/local/tmp"

get:

C:\Users\Anna>adb push fre3vo /data/local/tmp

cannot stat 'fre3vo': No such file or directory

when I first enter "adb shell" and then "adb push fre3vo /data/local/tmp"

get:

C:\Users\Anna>adb shell

$ adb push fre3vo /data/local/tmp

adb push fre3vo /data/local/tmp

adb: permission denied

$

what's the problem?
[G2 and Desire Z General] hedgehogmd:
Thanks Worked Great On My G2.
[G2 and Desire Z General] Nipqer:
2pizzaua: You do not have fre3vo in the directory you are running adb from/cmd is pointed to (C:\Users\Anna)

Move it there and it'll work.

Also, any command starting with adb has to be done OUTSIDE of shell, otherwise it'll throw a 'adb permission denied error'

Hi all,

I have rooted my phone 6 months ago, then I have unrooted it just to check what HTC have to offer this days

My phone is HTC Desire Z

Now I want to rrot it again and I have a question:

Before I proceed to he guide on XDA Wiki, can I directly install the original HTC Froyo ROM without using all the methods here?

When I unrooted my phone I keeped the S-off, didn't restore the part7 back-up

Having S-off means I can directly install the 1.34 firmware? Or do I have to chagen that version number to allow me to downgrade?

Thanks!
[G2 and Desire Z General] sstair:
I found this sentence to be confusing:

I thought it was telling me that the fre3v0 file SHOULD be in the fre3vo.zip file, and that the fre3vo.zip file should be in the platform-tools directory.

Perhaps if it was changed to:

To elaborate, extract the fre3vo file from inside of the fre3vo.zip file and the misc_version file from inside the misc_version_01.zip file, and place them in your platform-tools directory.).
[G2 and Desire Z General] antivirus1:
I am getting this error...:confused:

C:\AndroidSDK\platform-tools>adb push misc_version /data/local/tmp/misc_version

[G2 and Desire Z General] Flash05:
is my hboot ok and be able to proceed with changing of hboot?
[G2 and Desire Z General] Nipqer:
antivirus1: You do not have misc_version in C:\AndroidSDK\platform-tools.

Thats what that error means.

Flash05: How do you mean is your hboot ok? If it wasn't you'd have a brick.

The Radio on the other hand, is exploitable so you can use gfree and root.

What state must the phone be in for the 1st section of this how to? I currently am only able to communicate with mine in fastboot usb....It responds with a phone serial when I type fastboot devices....What state do I need the phone in to run the first section of this how too? I do have it connected as usb tether not just charge only and phone is booted up 2.3.4 and also just tried in hboot usb plug..no luck... when I type adb devices it does not see the device just a blank black line...Any ideas?

EDIT Deleted all entries in tools back to the most basic stuff %SystemRoot%;C:\android-sdk-windows\platform-tools;C:\android-sdk-windows\tools there were a bunch of av entries and old program crap...then I reinstalled HTCdriver.exe, changed set connection type on phone to usb tethering, Plugged mt4g into the usb on the audio card (opposite side laptop usb port) now it can see my device yea!

Problems downgrading MYT4G

Hi Guys

I am having problems downgrading.

Everything in the procedure seems to work, except the manual or fastboot downgrade.

When trying manual, I get during the HBOOT SD checking, No Image or No image or wrong image! messages. (see attachments)

When trying the fastboot method I always get:

C:\android-sdk\platform-tools>fastboot-windows flash zip StockRom.zip

sending 'zip' (319593 KB)... OKAY

writing 'zip'... INFOadopting the signature contained in this image...

INFOsignature checking...

FAILED (remote: 12 signature verify fail)

I downloaded the correct image for the MYT4G according to this procedure, with the correct md5 checksum.

The current software version of the MYT4G is 1.28.531.10

The HBOOT is 1.44.0007

The success range for rooting is /data/local/tmp/fre3vo -debug -start 20000000 -end 2FFFFFFF

All goes well, I get Root access (# symbol in shell)

# dd if=/dev/block/mmcblk0p17 bs=1 skip=160 count=10

dd if=/dev/block/mmcblk0p17 bs=1 skip=160 count=10

1.00.000.010+0 records in

10+0 records out

10 bytes transferred in 0.001 secs (10000 bytes/sec)

I get HT17BTB01018 fastboot at fastboot-windows devices

Any ideas?

Cheers!

[G2 and Desire Z General] Nipqer:
Signature verify fail sounds like a corrupt zip, you should check the md5 sum, and/or redownload the rom.

-Nipqer
[G2 and Desire Z General] gardacus:
Hey Nipqer

Thanks for your response.

According to the checksum, the zip is ok. I checked this before I posted. Also wrote it in my post.

Any ideas?
[G2 and Desire Z General] Nipqer:
My bad, should really read it properly.

The problem is you have a mt4g SLIDE (Doubleshot)

Whereas this guide is for the mt4g (Glacier)

-Nipqer
[G2 and Desire Z General] gardacus:
Dohhh... Alright. Well that's of course my bad... I am simply too unfamiliar with this phone at all. Friend of mine bought it in the USA, and asked me to unlock it for the Dutch networks...

Allright I will try to find if it is also possible to unlock the Slide.

Thanks for your help!
[G2 and Desire Z General] Setherio:
No, the location is apparently different on every phone. That was the location I received when I personally did the test. I have yet to see two people provide me with the exact same location. However, The location is in the general area of FBA* - FBB*, though on rare occasions I have seen it occur in the FAB*. When I initially wrote this guide, I based the first estimate on the most probably location found which was FBB*. It wasn't until about a couple months afterwards that I was helping someone and they reported the exploit location was in the FAB* range.

So it is quite possible that the exploit location for your device is under the initial attempt. If it does not work, you must reboot the phone, and try again using an alternate search. Examples are given in the guide under "Gaining Temp Root" #7b.

I would try sticking with the higher set if FAA00000 - FFFFFFFF doesn't work. Maybe try widening the parameters as well.. something like this should do the trick.

$ /data/local/tmp/fre3vo -debug -start F9000000 -end FFFFFFFF

It might take a while to scan and a little redundant (if you already tried FAA00000 - FFFFFFFF, but no harm will come and it's not a bad idea to double-check.

[G2 and Desire Z General] Flash05:
after downgrading to 1.405, and following this instructions for root, S-OFF, and CWM (http://wiki.cyanogenmod.com/wiki/HTC_Desire_Z:_Rooting), can i proceed with loading Virtuous Sense instead of CM7 via recovery?

or must go first to CM7 then Virtuous sense?

thanks.
[G2 and Desire Z General] youngquazy:
I have a MyTouch 4G that I just received and it has a new hboot that says 0.89.0006 and its one I've never seen before. I downgraded mytouch 4gs before using this guide without a problem before. But when I get to the part where I load the original rom back on the phone, it fails, rather I do it through adb or through the bootloader on the phone by putting it on the sd card. Would this new hboot be the cause? Like I said, I've downgraded other mytouches before using this guide without a problem but they had different hboot
[G2 and Desire Z General] Nipqer:
Flash05: Go ahead and flash any rom you want, just remember to make backups and wipe data/factory reset between roms.

youngquazy: Did it throw an error message? As far as I know, the hboot version shouldn't affect the flashing, as it looks at the misc_version number, to see whether the rom we are loading is a newer version or not.

-Nipqer
[G2 and Desire Z General] Setherio:
I'm fairly sure it does work as it is the exactly one I used 2 days ago to root my brother-in-law's myTouch 4G. Are you sure the file didn't get corrupted during the download processes or when moving it to the sdcard? What errors are you getting? Any further information could help.
[G2 and Desire Z General] lxcrazzydxl:
it worked last night..i guess my internet was going slow..i kept trying so yeah..
[G2 and Desire Z General] opensourcefan:
Fantastic Guide!!!

Just remember, after flashing PC10IMG and booting back up, don't forget to re-enable USB Debugging LOL, otherwise adb will say "error: device not found" when trying to downgrade fastboot. For those of us who's brains are farting at the time.

My starting point was:

2.3.3

Baseband - 12.57.60.25U_26.10.04.12_M

S.W. 2.42.666.8
[G2 and Desire Z General] Flash05:
finally! rooted, s-off! thanks to this guide and Nipqer for answering my questions!

im using virtuous, how or where can i get instruction how to install the old-style tv/screen off when pressing the power button? sorry OT. :(
[G2 and Desire Z General] bassbox:
so if i got it right

this really grants me (temp) root before downgrading so i can do a complete backup of all my stuff and then root and enjoy custom roms as i did on my g1? :D

HTC Desire Z (german vodafone branded)
[G2 and Desire Z General] Flash05:
^ yes. will give you temp root. but not stable. you have to rerun the fixsu if root is not granted and try to run again the app.
[G2 and Desire Z General] bassbox:
well im stuck at

Temp-Rooting to Backup - Step

everything seemd to work fine.. but titaniumbackup says it hat no root access (and superuser doesnt ask me to grant em)

still got root in adb shell and executed all lines before that step

nevermind, working now. just did this:

> adb shell chmod 755 /data/local/tmp/fixsu.sh
> adb shell /data/local/tmp/fixsu.sh

once more.. ? ^^ :D

2.3.4 Downgrade Issue - Any Clue?

I have gone through this guide and I got to the point where it found the exploit section. I had downloaded the files required MISC_VERSION and FRE3VO, etc per instructions.

I enter the command to ADB push MISC_VERSION and I get an error that it can't find the files. (Sorry I don't have the exact error right now, working off memory from last night.)

I verified the files were there in the path specified. Could something be wrong with the file itself?
[G2 and Desire Z General] petarpLab:
you are running the push command form a folder misc_version is not in

cd to your platform-tools or open 'my computer', hold shift, right click on the platform-tools folder and choose 'open cmd here'. work from that cmd.
[G2 and Desire Z General] Hatefly:
Hmm. I'm pretty sure that's exactly what I did. Maybe I didn't by mistake. Question though, if that was the case, would I have been able to run the exploit? IIRC, I had FRE3VO in the same platform-tools folder.

I was using c:\android-sdk\platform-tools\(all the files required for this here)
[G2 and Desire Z General] -Alaa-:

Can anyone please post a mirror or a link?
[G2 and Desire Z General] petarpLab:
in that case misc_version is not in platform-tools.

your troubles can be solved in no time at #g2root. doing it here in the forum is frustratingly slow.
[G2 and Desire Z General] Hatefly:
OK, i'm back at it again. I made it past the point I did before by changing the directory around a bit. Not sure why it's "sorta" working this time. I am at the point where I need to do the command # ./misc_version -s 1.00.000.0 this is giving me an error misc_version: not found

am I missing something? Is the "." in the ./ supposed to be the filepath on my computer?

Also, I found the #G2root IRC logs but I don't know how to communicate on that. Do I need to get an IRC program and find it somehow? Sorry for that major noob question :( Never needed it before.

Oh yeah, one more question, what is this misc_version.c file for? should I use that instead?
[G2 and Desire Z General] RaffieKol:
One more thing what method would u use to root your phone after this - Peace
[G2 and Desire Z General] Setherio:
I used the method posted on Cyanogen's Wiki:

http://wiki.cyanogenmod.com/wiki/TMobile_G2:_Rooting
[G2 and Desire Z General] bagdroid:
Hi, thanks so much for this.

I have followed your instructions to the letter - got root # no problems.

The problem I am having is Downgrading - when my phone is checking the PC10IMG.zip it gives the following error:

CID incorrect!

Update fail!

Press (POWER) to reboot.

My phone is Australian Vodafone Desire Z with the latest 2.3.3 Gingerbread OTA update.

I don't know what I am doing wrong. Any help appreciated. I am going to keep trying in the meantime.
[G2 and Desire Z General] bagdroid:
OK, I worked out I needed to make a goldcard.

I used the instructions from http://forum.cyanogenmod.com/topic/21681-cid-incorrect-update-fail/

and it worked!

So far so good....
[G2 and Desire Z General] RaffieKol:
also make sure to flash the newest radio after doing this...

"for some reason I couldn't power on my phone unless I plugged it in the usb without the battery then stick the battery in and it would power on"

after I flashed the newest radio this was fixed

just posting this just incase someone else runs into this but either way this method works really nice :)

HI,

If I have only Temp Root from top this topic so Can I install BusyBox and use for example Titanium backup ?
[G2 and Desire Z General] Nipqer:
As far as I know, fre3vo only gives adb shell temp-root.

So applications that need root (such as titanium) will not work.

-Nipqer
[G2 and Desire Z General] drastys:

[G2 and Desire Z General] iDylan1357:
just to confirm it, this method works perfectly on the myTouch 4G as well :D
[G2 and Desire Z General] Setherio:
Thanks for that confirmation iDylan1357!

Do you by any chance recall what version number you used for the mT4G? And when you used fre3vo, did the memory range you used? o.O;
[G2 and Desire Z General] inteligent:
I have a HTC Desire Z.

I have a number 2.42.405.2 software (Android 2.3.3) I can use this guide? I ask because I see that there is a topic mentioned in the version 2.13.531.8.

The next question concerns the ROOT, if I understand it is doing under the guidance of 1 to 7 points in the "Gaining Root temp" I get without doing any temproot Downgrade? But still I have the S-ON on the phone?

I have one last question what I have to do if in the future I would like to upload your CustomROM? How do the S-OFF?

Sorry for my English but I hope that you have understood.

temp root on adb shell is needed to fake current version information. Hence the steps 1-7. Unless goldcard is needed (check you CID), the whole procedure is pretty straightforward, thanks to excellent tools. For creating a goldcard, there are excellent guides as well. Good luck and happy flashing. :D
[G2 and Desire Z General] trzype:
Yes u can.

Tak jak napisałeś. Gaining Temp Root pkt 1-7 dają tymczasowego roota. Potem zmieniasz wersję, robisz downgrade, robisz stałego roota, S-OFF i wgrywasz custom roma.

Temp root jest tylko po to aby zrobić downgrade ponieważ na Twoim obecnym sofcie się nie da.

Potem wgrywasz custom roma albo oficjalnego z którego zrobiłeś downgrade, ale już z rootem (do znalezienia na forum)

@Setherio can I translate ur guide to polish language and post it on polish forum like i done with g4rb4g3 [GUIDE] Downgrade your Desire-Z from 1.72 to 1.34 (and get root and S-OFF)?

This guide does not work for the Bell Desire Z -_-

---------- Post added at 05:39 AM ---------- Previous post was at 05:14 AM ----------

I was able to get through the temp root part...but after that idk what happens -_-

http://pastebin.com/bALdpCwB

There is my copy of the cmd...

While doing it, I did leave out to asterisk after /tmp but I will even go ahead and do it again and paste another copy of my cmd. & yes, I will reboot my phone.

Now instead of being able to enter the cd /data/local/tmp it just gives me the # sign. I also don't know why it's saying adb out of date. I downloaded it yesterday and tried this process several times and it wasn't saying that. It might be because I also have mini adb.

http://pastebin.com/pnZ3hBuf

This is all very frustrating and if anyone could help me it would be GREATLY appreciated. I have the Bell Desire Z (with S-Off). Some people have said that this guide works, however I am guessing it doesn't.
