Did you try making a goldcard? I don't see you running flashgc in that log.

Hi Nipqur,

Thanks for your speedy response. I did make the gold card, when i try with zip file on the SD Card, bootloader doesnot recognize the file. So i tried running RUU from Windows and fastboot method!

Sorry for the stupid question, but what is flashgc? Does it mean flash goldcard?

(First, sorry for my english... If anyone speak french...) :eek:
My DZ is root, S-on
Hboot 0.85.0015 / Android 2.3.3 / Build 2.42.405.2

I want to S-off my DZ and flash a new rom, so I follow your thread step by step but the manual downgrade seems not work (the Zip is downloaded but nothing happen after: the DZ reboot and anything has changed), so I try the 'fastboot downgrade' and I have the following error:
C:\Program Files\Android\android-sdk\platform-tools>fastboot-windows devices
HT0BHRT02168 fastboot

I tried three times again with the same result.

I don't undersand why (and how) my DZ can be root (with SU and Rom Manager working in it) but can't be S-off.
Can I flash a new rom if I'm S-on?

Thanks for your help and very sorry for my froggy english :D

EDIT: If my DZ is rooted, it's thanks to HTCDEV... Therefore, I suppose I had to try to relock it before retry this thread. So, I follow the new thread I've found (how to get root with HTCDEV unlock) and I re-come here after (right?)

You had used HTCDEV, which prevents flashing new official roms.
Which is what the 99 unkown fail is
So yes, as per your edit. you can relock then do this method followed by gfree to have a totally unlocked phone.

Might want to put in the OP that flashgc is optional, new people will try to push that file if they don't have a goldcard and get a file and directory error

It seems even after scrolling through the 40+ pages and trying different solutions, I'm still receiving the same permission denied error when attempting to change the misc_version.

Code: 
C:\android-sdk-windows\tools>adb shell chmod 777 /data/local/tmp/*
C:\android-sdk-windows\tools>adb shell
# cd /data/local/tmp
cd /data/local/tmp
# chmod 755 ./misc_version
chmod 755 ./misc_version
# ./misc_version -s 1.00.000.0
./misc_version -s 1.00.000.0
./misc_version: permission denied
# chmod 777 ./misc_version
# ./misc_version -s 1.00.000.0
./misc_version: permission denied

Is there anything that can be done here? I really hope that I didn't mess anything up with previous root attempts.

I dit it !!!!!

YESSS! I DID IT! :D

After relock hboot, re-root, S-off, flash recovery and a new rom (andomadus ICS... super fine and works great in a basic DZ!).
Note, in the (touch) recovery (after fastboot), it's not Vol and power to navigate and validate, but ONLY the trackpad of the DZ (I've searched for a couple of hour before find it).
If you know this soluce, the Gapps are easy to flash (why they aren't installed yet?)

Thanks for everyone and great job (I love you!) :cool:

Chances are you pushed the misc_version directory.
in adb shell, after 'cd /data/local/tmp' run 'ls -l' (note: thats Ls -L (small L's) not 1s -1)
if the line that misc_version is on starts with:
drwxrwxrwx; it means you pushed the directory, in which case you need to:
cd misc_version
chmod 777 *
./misc_version -s 1.00.000.0
cd ..

Gapps aren't pre-installed by default because the gapps are proprietary code, so you need a licence to include them in open sourced roms.
Sense based roms are allowed to have them because Sense includes them by default.

Hey all,

Looking for some help. I have rooted and s-offed using strawmetals guide (which worked great) but when I install ILWT or CM7.1 and reboot it just sticks on the boot up animation. I left ILWT for 10 mins before I pulled the battery. Running the recovery version off the microSD and it boots just fine.

Anything I can check as really keen to get ILWT running.

That "2.16.531.510+0 records in" tells you what version you're running (or if you modify it, tells you what version it thinks it's running). Try running the misc_version command again.

Code: 
# /data/local/tmp/misc_version -s 1.00.000.0

Then run the dd command like you did and it should return:
1.00.000.010+0 records in

Tried that..no luck.. and now it looks like I have no recovery..hmm think I need to temp root, restore the original recovery and start over, only this time go do the htc oem unlock first.
Anyone have a copy of the latest stock recovery image I could use?

Wait... Now I'm a bit confused... No recovery - at all - are you sure? o_O;

And yeah, you need to be temp rooted to change version number, sorry, I should of been more clear on that. Run the first couple steps in the guide again. the fre3vo and misc_version ones. Feel free to join #g2root on irc.freenode.net

And we can help you in real time if you'd prefer.

How didn't it work? That's what you need to do.
You should already have stock recovery (red triangle, exclamation mark?), I don't know why you're bothering with that mode anyway.
Don't use htcdev to unlock, its absolutely terrible.

    [GUIDE] Downgrade G2 (2.3.X) & DZ (2.3.X) & mT4g (2.3.4) & DHD w/ S-ON to Stock Froyo

    This guide is written for anyone who has "Stock Gingerbread" and wants to downgrade their phone which originally had "Stock Froyo". The following is a list of phone models this guide is intended for and that are known to work:

    Working Phone Models:
    • G2 (Vision)
    • Desire Z (Vision)
    • myTouch 4G (Glacier)
    • Desire HD (Ace)

    It should also be noted, this guide WILL NOT work with the following:

    Special Notes


    Table of Contents
    • Introduction
      1. Gaining Temp Root
      2. Changing Version Number to Allow Downgrade and Gaining SuperCID with a Goldcard
      3. Temp-Rooting to Backup (*Optional*)
      4. Downgrading
        • Manual Downgrade
        • Fastboot Downgrade
    • Sources
    • Troubleshooting
    • Change Log
    • Attachments


    I) Introduction
    This guide is written with the assumption that the user has previously used "adb". If you are unfamiliar with "adb" or do not even know what "adb" is, download the Android SDK (found at http://developer.android.com/sdk/index.html). There are a couple guides to help you get started setting up the Android SDK and understanding ADB. If you have not installed the Android SDK or you are unfamiliar with ADB, please take some time and read a couple guides to get a basic understanding of it.


    I - 1) Gaining Temp Root
    1. Download the attached files, unzip them, and place the files in your platform-tools folder. To elaborate, place the fre3vo file inside of the View attachment fre3vo.zip file in your platform-tools folder and the misc_version file inside the View attachment misc_version_01.zip file in your platform-tools folder.
    2. Make sure you have your sdcard inserted in your phone, and you are NOT in USB Storage Mode, and your sdcard is NOT FULL.
    3. Run the following command to verify the exploit has access to what it needs. (Only the first line is the command. The second line should be the result returned if all goes well.)
      Code: 
      [B]> adb shell cat /dev/msm_rotator[/B]
[I]/dev/msm_rotator: invalid length[/I]
    4. If you received the same message, you're good to continue on. If not… refer to the troubleshooting section of the guide before you continue.
    5. Run the following commands from your platform-tools directory.
      Code: 
      [B]> adb push fre3vo /data/local/tmp
> adb shell
$ chmod 777 /data/local/tmp/fre3vo
$ /data/local/tmp/fre3vo -debug -start FAA90000 -end FFFFFFFF[/B]
    6. After you enter that command, you should see something similar to the last few lines in the following displayed.
      (It may take a minute or two. From what I can tell, this appears to be the quickest method as the exploit seems to be found in the latter regions.)
      Code: 
      [I]Buffer offset:      00000000
Buffer size:        8192

Scanning region fb7b0000...
Scanning region fb8a0000...
Scanning region fb990000...
Scanning region fba90000...
Potential exploit area found at address fbb4d600:a00.
Exploiting device...[/I]
      • If the exploit works, you will be kicked out of ADB shell, proceed to Step #8.
      • If the above does not work, and fails, you can try the following, and hopefully one will work, try the following (you must reboot your phone before you try another set):
        Code: 
        [B]$ /data/local/tmp/fre3vo -debug -start 10000000 -end 1FFFFFFF
$ /data/local/tmp/fre3vo -debug -start 20000000 -end 2FFFFFFF
$ /data/local/tmp/fre3vo -debug -start 30000000 -end 3FFFFFFF
$ /data/local/tmp/fre3vo -debug -start F0000000 -end FFFFFFFF
$ /data/local/tmp/fre3vo -debug -start E0000000 -end EFFFFFFF[/B]
    8. If you did get kicked out of adb shell, open it again. You should now see # instead of $, thus granting you temp root. Go ahead and exit out of shell to proceed to the next stage.
      Code: 
      [B]> adb shell
# exit[/B]


    I - 2) Changing Version Number to Allow Downgrade and Gaining SuperCID with a Goldcard
    1. If you followed the first portion of this, you should of unzipped View attachment misc_version_01.zip ad View attachment flashgc.zip in the platform-tools directory.
      If you haven't done that yet, do that now and then run the following commands from your platform-tools directory.
    2. Code: 
      [B]> adb push misc_version /data/local/tmp/misc_version
> adb push flashgc /data/local/tmp/flashgc
> adb shell chmod 777 /data/local/tmp/*
> adb shell
# cd /data/local/tmp
# ./misc_version -s 1.00.000.0[/B]
[I]--set_version set. VERSION will be changed to: 1.00.000.0
Patching and backing up partition 17...[/I]
[B]# ./flashgc[/B]
      *Note: If you get the following error, please make sure your sdcard is inserted in your phone and is NOT mounted to your computer (ie: make sure you are NOT in USB Storage Mode). This is a fairly common error and/or oversight many people tend to miss. Please double check this before continuing.
      Code: 
      Error opening backup file.
    3. Code: 
      [B]# sync[/B]
    4. Double check and make sure everything looks good so far by running the following command (still in adb shell).
      Code: 
      [B]# dd if=/dev/block/mmcblk0p17 bs=1 skip=160 count=10[/B]
[I]1.00.000.010+0 records in
10+0 records out
10 bytes transferred in 0.001 secs (10000 bytes/sec)[/I]
    5. BE SURE TO BACKUP ANY DATA!!!***


    I - 3) Temp-Rooting to Backup
    If you have nothing to back up or don't care to back anything up, proceed to the next section.
    Credit goes to Nipqer from #g2root for providing me with this method.
    1. Download the attached file: View attachment Vision-fre3vo-temp-root.zip
    2. Extract the contents to your platform-tools directory.
    3. Run the following commands in command prompt while in platform-tools directory:
      Code: 
      > adb push su /data/local/tmp/
> adb push busybox /data/local/tmp/
> adb push fixsu.sh /data/local/tmp/
> adb install SuperUser.apk
> adb shell chmod 755 /data/local/tmp/fixsu.sh
> adb shell /data/local/tmp/fixsu.sh
    4. Download a backing up application such as...
    5. Make a backup!


    I - 4) Downgrading

    I - 4a) Manual Downgrade
    1. Rename the downloaded rom to it's proper update name:
      (Please note, the filenames MUST be all uppercase except for the extension, and if file extensions are hidden, do not include ".zip"):
      • G2: "PC10IMG.zip"
      • Desire Z: "PC10IMG.zip"
      • myTouch 4G: "PD15IMG.zip"
      • Desire HD: "PD98IMG.zip"

    2. Place the zip file in the root of your sdcard.
    3. Reboot your phone into bootloader by typing the following command:
      Code: 
      [B]> adb reboot bootloader [/B]
    4. After your phone has entered bootloader, press the power button. It will then scan for the associated rom file and ask you to update by pressing a key.
    5. Press the key it requests to perform the update.
      DO NOT INTERRUPT THIS PROCESS.
      Your phone will reboot once or twice - this is completely normal.
      This process will take roughly 5-10 minutes so make sure your phone is plugged in, either to an outlet or your computer.
    6. Once the process is finished, it will ask you to reboot by pressing a key. Press the associated key and it will reboot into the Stock Froyo rom!
    7. After booting into Android 2.2, DO NOT update the OTA that is around 70MB. That is the update to Gingerbread. There is one update that will come before that, that is a lot smaller in size, which is the WiFi-Calling update - that update is okay to install.


    I - 4b) Fastboot Downgrade
    1. Rename the downloaded stock rom "StockRom.zip" (if extensions are hidden, rename it "StockRom").
    2. Place the downloaded stock rom zip file in your platform-tools directory.
    3. Download the attached file View attachment fastboot.zip. In the zip archive there are three folders, "windows", "mac", and "linux".
    4. Extract the file from the associated with your operating system and place it in platform-tools directory.
    5. In command prompt, type the following command to reboot into bootloader:
      Code: 
      [B]> adb reboot bootloader[/B]
    6. Make sure your device is recognized by typing the following command.
      Code: 
      [B]> fastboot devices[/B]
    7. If you device is recognized, it should return a serial/model number.
    8. Code: 
      [B]> fastboot oem rebootRUU[/B]
    9. Your phone should now reboot into a black screen with a gray/silver "HTC" logo on it.
    10. Next we flash the Stock Rom. This may take a few minutes as it transfers the file to the phone then attemps to update (downgrade).
      Code: 
      [B]> fastboot flash zip StockRom.zip[/B]
    11. In rare cases the flash stops and the user gets a warning to repeat the flash immediately - no panic, just run the "fastboot flash zip StockRom.zip" (only this command, not the rebootRUU one) again and it will work.
    12. When it finishes, wait a minute or two (just in case) then reboot your phone by typing:
      Code: 
      [B]> fastboot reboot[/B]
    13. After booting into Android 2.2, DO NOT update the OTA that is around 70MB. That is the update to Gingerbread. There is one update that will come before that, that is a lot smaller in size, which is the WiFi-Calling update - that update is okay to install.

So a special thanks to, Cimer, strawmetal petarpLab, iDylan1357, asharma5290, guhl, pierre_ja, and skorgon from #g2root. And I would also like to recognize and give a major thanks to Nipqer whom offers a lot of support with constant responses helping assist those whom ask for help both in this thread as well as on IRC. And he is always making sure I keep this as updated as it can be.

    Thanks for the tips Cimer, I edited the post, hopefully that clarifies it a bit more.

    I've been a quiet browser here on XDA for quite a while but I believe that was actually the first post I made =3 It took me a while to try to get it formatted... fluently / tried to make it easy to read and follow.

    And hey, if it wasn't for you all posting the logs from #g2root, I would of never gotten my G2 back to being rooted. :) I think I had like 8 different pages open when I was doing it, reading the chat log, reviewing the pastebin data, et cetera. But it worked, after searching every day, the trick has been found.

    On a side note, I picked the range "-start FAA90000 -end FFFFFFFF" because it appears that the exploit is most likely within that range. It was for yours "FBB47C00:1400", mine was "FBB4D600:A00", and a friend of mine was also an FBB*.

    I included the guide for rooting in the pdf given in the op. You could use that.
