[Q] Unrooting for warranty return

I rooted my phone using the gfree method outlined in the wiki, but made a Nandroid backup of stock before I started anything. I restored the backup; is there anything else I need to do before sending it back?
I noticed that still have the Superuser app in my app drawer, and I wasn't able to follow the instructions for S-OFF here (http://forum.xda-developers.com/wiki/index.php?title=HTC_Vision#Turning_S-On) as it said "Permission denied" when I type cd /data/local (I also noticed that I don't have the /data/local folder anymore on my sd card).

Gfree gives you an option to turn S-off or S-on, go back to the wiki and re-read it, the code below is copied from the Wiki and I highlighted the options in red for you, just run gfree again with the -s option
Code:
gfree usage:
gfree [-h|-?|--help] [-v|--version] [-s|--secu_flag on|off]
-h | -? | --help: display this message
-v | --version: display program version
-s | --secu_flag[COLOR="red"] on|off[/COLOR]: turn secu_flag [COLOR="Red"]on[/COLOR] or [COLOR="red"]off[/COLOR]
-c | --cid <CID>: set the CID to the 8-char long CID
-S | --sim_unlock: remove the SIMLOCK
-f | --free_all: same as --secu_flag off --sim_unlock --cid 11111111
As far as superusers app, just go into the app manager and remove it.

Sorry, I should've clarified that I don't have gfree anymore. I tried again and this is the prompt I get:
$ su
su
# cd data/local
cd data/local
# chmod 777 gfree
chmod 777 gfree
Unable to chmod gfree: No such file or directory
# ./gfree
./gfree
./gfree: not found
#

Push the gfree file back to data/local and rerun the commands except with -s option read the wiki again and use the right commands.

All right, got my phone back to stock unrooted and with S-ON. Here's what I did (note that my circumstances my be different than yours so try this at your own risk):
I rooted and S-OFFed using the rage (v 0.03-this will come into play later) method on the wiki (http://forum.xda-developers.com/wik...sion#Rooting_the_Vision_.28G2.2FDZ.29_and_DHD). I did this right when I got the phone, so no OTA update (I had 1.19). Downloaded ROM Manager and did a Nandroid backup at this point (in my above post I said I made a backup right at the beginning which I was mistaken on). Then I went ahead and flashed CyanMod.
Phone earpiece broke, so I had to get the phone back to stock. First I restored my backup ROM (so back to 1.19 again). Used the unroot guide (http://forum.xda-developers.com/showthread.php?t=835971), and during step one, I got the following error:
E:Board does not support mtd utils.E:Failure at line 344:
write_raw_image PACKAGE:boot.img BOOT:
Installation aborted.
Failure at line 6:
install_zip SDCARD:/stock_root.zip​Some others seemed to get this error as well and it looked benign. Continued and rebooted the phone. Figured this would be a failure, so I followed the HexEditor steps. Turns out the misc.img file was already the right version, but I renamed it and ran dd if=/sdcard/miscnew.img of=/dev/block/mmcblk0p17 just in case.
Step 2 ran without any problems, so now I had a stock phone with S-OFF. To turn it back on, I temp rooted the phone (just follow the TEMP Root steps in the wiki). I then tried to follow the S-ON directions on the wiki (http://forum.xda-developers.com/wiki/index.php?title=HTC_Vision#Turning_S-On), but the phone would automatically reboot after the dd line while not changing S-OFF.
Then I realized that I could use ./gfree -s on to turn S-ON since I was using 0.03, which worked perfectly. Rebooted to remove the temp root, and did a factory restore for good measure, and I believe I have a fairly pristine G2 ready for replacement.
Thanks to all the wikis and threads for their help!

I have a question about restoring to factory settings. Cant you just use the RUU from HTC (if you have a Desire Z that is) and just run that? Wont that just put it back to factory settings?

[Q] Unable to unlock TMobile G2

Hi all,
I recently obtained the TMobile G2 and its unlock code.
I inserted a foreign SIM and entered the unlock code.
However during the unlock reboot process, i manually rebooted it.
Since then it has not asked for any Unlock code no matter what.
I have also tried factory reset as well but it did not help. Please support!!

But the sim is still not showing any network? Make sure the sim is not old/out of date/.... make sure it is working in another handset. If it is, then you will need to gfree root and super Cid as there have been issues regarding network unlock codes.

I tried two sim cards which worked fine on the other phone, however did not work on my G2 - showed up as no network.
what is gfree root and super cid? any pointers on that?

Just use gfree, it will SIM unlock as well as giving you full radio S-OFF and SuperCID. See http://forum.xda-developers.com/wik...Phone.2C_Set_SuperCID.2C_and_Turn_Radio_S-OFF . You will need at least temp root to run it.

Thanks folks...
After i use gfree/ do a temp root. How to i verify if the phone is unlocked?
nd how to revert back from that root?

To verify it is unlocked you will need to put in a different SIM card from the network that the phone was locked to, and see if it will recognise it.
If you only did a temp root, then if you reboot you shouldn't have root any more.

I temp root the phone- i try to insert new SIM i need to reboot rite and ill loose the root.
http://forum.xda-developers.com/wiki/index.php?title=HTC_Vision#Rooting_the_G2
this page says- "......
@CID: 11111111 <--- this response means you have superCID!
@SIMLOCK= 00 <--- this means your simlock is off.
@secu_flag: 0 <--- this means your radio is S-OFF.
....."
now what should the value be for "@SIMLOCK="??

You can run gfree without a SIM or with your old SIM in, you don't need to put in the new one that the phone won't recognise whilst it's locked.
I'm not sure I understand your last question. I don't know what the value will be before you run gfree to unlock it, it will have some sort of value which will equate to the network it's locked to. After unlocking with gfree it should set that value to 00 as it shows.

Oh! my mistake.. if i unlock that means the SIMLOCK=00.
Ill try it out now
Thanks for the help steviewevie and wileykat as well!!

Just run "gfree -f". There's no point in only unlocking part of it. Might as well own your phone... it is yours, right?

yes.. what does that command do?

-f | --free_all: same as --secu_flag off --sim_unlock --cid 11111111

Neat!! Thanks..
This is what i should do -
Unzip the gfree_temp-root.zip files to a folder.
And using adb-
$ adb push su /sdcard/su
$ adb push Superuser.apk /sdcard/Superuser.apk
$ adb push rage /data/local/tmp/rage
$ adb push busybox /data/local/tmp/busybox
$ adb push root /data/local/tmp/root
$ adb shell chmod 0755 /data/local/tmp/*
ON The PHONE:
Launch Terminal Emulator
$ /data/local/tmp/rage
Wait for the message: "Forked #### childs."
Menu > Reset Term - Terminal Emulator will exit.
Launch Terminal Emulator, it Force Closes. Launch a second time, and you'll have a root shell.
Now i have temporary root:
then in the terminal emulator
# ./gfree -f
:: This should unlock for all networks and after reboot the phone would be unrooted.
Is this correct?

You left out some commands, like the really important one where you set the permissions on gfree, just make sure to follow the guide to a "T" and you should be good. If something happens, I'm sure that one of us can help you.
EDIT: And the point of using GFree is so that its rooted not unrooted. If you don't understand it fully, I wouldn't do it, bad things happen when people try things that they don't fully understand.

Edit - never mind, didn't notice the other answers from my phone.

[Q] - Strange thing with Root and Version Number

Hi, it happens a strange thing to me. I'm on Modaco customized ROM and i can't gain root.
I start my phone from recovery console (clockworkmod is installed) and it shows:
ACE PVT ENG S-OFF
(radio-26.03.02.08_M)
Os Vers. - 1.32.707.1 and CID 11111111 so I should've root access.
When I boot my ROM, and I go to check version number it says 1.72.
So I, Enable USB-Debugging on phone, do thes commands:
Code:
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/
*Start the Terminal app on phone and type:
Code:
/data/local/tmp/rage
* Wait until I see the message "Forked #### childs.", reset Terminal (menu > Reset Term). The Terminal app will close, launch it again. It will force close, launch it again.
Then when I try to launch terminal again my phone freezes. And I can't get root access. Titanium backup says that Superuser application close in an unknown way and also through an application called "Root Check" it says that i'm not rooted. How's it possible? What I'm supposed to do? I also tried with su command from terminal...
Thanks

Someone can please help? It's really annoying

oK, you can change to [SOLVED]
I downgraded again with this rom: RUU_Ace_HTC_WWE_1.32.405.3_Radio_12.28b.60.140e_26.03.02.15_M3_release_155032_signed.exe
And I flashed with the new ROM Android Revolution HD, now everything worsk perfectly

[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'
-Nipqer

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

[Q] How to root Desire Z without USB debugging

Hi. I did a factory reset and now I cannot get past the white HTC welcome screen. I don't have the phone rooted, hboot says S-ON. I had USB debugging disabled when doing the reset, so now I can't turn it on (since I won't get anywhere near the actual system).
Also, I don't know if this is the cause of not having USB debugging on - adb can't seem to find my device. When connected, it shows HBOOT USB PLUG, but adb devices returns an empty list..
Is there a way I can root/unlock the phone, without having debugging on, so that I can flash a recovery and a new system?
Thanks

Not too likely, adb will never work in bootloader mode but fastboot should. adb only works in os and recovery.
What you'll need to do is flash an RUU through bootloader or fastboot to get things working again. Check the development section here for a list of the latest RUUs for the vision
Sent from my Nexus 4 using XDA Premium 4 mobile app

I was swamped and got back to it by now. Thank you for your suggestion. It doesn't work though.
I downloaded the newest RUU from htcdev.com, the phone did get recognized by fastboot and the RUU installer seemed happy. However, when the actual update started, it got stuck on "Rebooting bootloader" or similar for over half an hour. That's when I decided to cancel it.
Next on, I tried steps shown here: androidforums .c o m/htc-desire-s/678126-desire-s-stuck-bootloader.html
fastboot erase cache - this got stuck on 'erasing cache', nothing happened afterwards
fastboot oem rebootRUU - this wrote "..." and nothing else happened
Is there anything else I can try?

How To Get R/W Access (Permanent Root / "Permaroot") using gfree v1.0[edit]
Prerequisites
Having the proper USB drivers installed - HTC Sync including Windows USB Drivers for the Vision
Disable auto-run or uninstall Visionary if you have it (It's important!)
adb (installed as part of the Android SDK.) See this guide on how to install/setup adb on your PC.
The HTC Desire Z with a firmware version higher than 1.34, T-Mobile G2 with a firmware version higher than 1.22 and the Desire HD with a firmware version higher then 1.32 have to be downgraded before proceeding.
Downgrading HTC Desire Z, T-Mobile G2 and Desire HD
For the 1.XX firmware HTC Desire Z follow this guide Downgrade DZ till step 12 and then come back.
For the 1.XX firmware HTC Desire HD follow this guide Downgrade HD and then come back.
For the 2.XX firmware HTC Desire Z/Desire HD and T-Mobile G2 follow this guide GUIDE Downgrade G2 2.13.531.8 (2.3.3 T-Mobile Rom w/ S-ON) & DZ 2.3.3 w/ S-ON" and come back. The history can be found in this thread New exploit works with Gingerbread! and Desire Z users see this posting of the thread Desire Z explanation.
Please use your brain when following these postings / guides. Especially make sure that you use a PC10IMG.zip for your device!
1. Necessary files
psneuter psneuter.zip (md5sum 89c2dec8d72d87b4c669f44dd31c8d17)
gfree v1.0 gfree_10.zip (md5sum 0bc9fc22bda897c765b02066f8a3c83b)
root_psn root_psn.zip (md5sum c8fe38ef55eb8951def9ff17b2eb99c1)
Superuser package su-2.3.6.2-efgh.zip (md5sum 43d9a40b63e916635d5ad7ca32433fab)
1.1. engineering hboot
Download the appropriate HBOOT for your phone:
T-Mobile G2: vision.hboot-0.76.2000.zip / Mirror (md5sum 7669AE12DC2FAA10AE555A164980EFD0)
HTC Desire Z: vision.hboot-0.84.2000.zip / Mirrors in this thread (md5sum 2CE1BDD5E4C1119CCFCECB938710D742)
HTC Desire HD: ace_glacier.hboot-0.85.2007.zip (md5sum df4fd77f44993eb05a4732210d2eddc6)
Note that the md5sums are for the actual hboot img contained within the zip file, not the for the zip file itself. Note also that the dz, g2, and dhd each use their own version of the engineering boot, as the phones are partitioned differently. (If you have previously installed the wrong HBOOT for your phone, you may need to reflash everything after partition 18)
1.2. clockwork recovery
Download the appropriate clockwork recovery for your phone:
ClockworkMod Recovery 5.0:
T-Mobile G2 and HTC Desire Z: recovery-clockwork-5.0.2.7-vision.img (md5sum 87a428549440894dbe2f96dd5efc4fb5)
HTC Desire HD: recovery-clockwork-5.0.2.0-ace.img (md5sum b8d77b9352dcbb41839e45342ea35658)
ClockworkMod Recovery 5.8 (touch):
T-Mobile G2 and HTC Desire Z: recovery-clockwork-touch-5.8.1.0-vision.img (md5sum b21aa5a0d593b6ebce880be3316ff64a)
HTC Desire HD: recovery-clockwork-touch-5.8.1.5-ace.img (md5sum fd6abfbc459663455a25b88ca7d77442)
Rename the file to 'recovery-clockwork.img'.
2. Copy the files to the phone
Before you can adb as described below you need to enable debugging in the settings on the phone. In Settings go to "Applications -> Development" and check the "USB debugging" option.
Connect the phone to the USB of your PC. The phone will stay connected during the complete procedure.
Make sure that you do NOT turn on USB storage. There has to be a sdcard in the phone and it has to be mounted to the phone!
In the commands to run below, $ or # represent the prompt and should NOT be entered as part of the commands (in Windows this will be something like C:\> instead).
Unpack all the zip files to a directory on your PC. Open a terminal (or command window) on your PC and change the current directory to where the files are on your PC and execute these commands:
$ adb push psneuter /data/local/tmp/
$ adb push gfree /data/local/tmp/
$ adb push busybox /data/local/tmp/
$ adb push hboot-eng.img /data/local/tmp/
$ adb push root_psn /data/local/tmp/
$ adb push su /sdcard/
$ adb push Superuser.apk /sdcard/
$ adb shell chmod 755 /data/local/tmp/*
2. clockwork recovery for T-Mobile G2 and HTC Desire Z
To copy your clockwork recovery execute the following command in the terminal or command window
$ adb push recovery-clockwork.img /data/local/tmp/recovery.img
3. Temporary root
In the terminal (or command window) execute these commands:
$ adb shell /data/local/tmp/psneuter
$ adb shell
after the last command you should have a root shell in adb (this is indicated by a # prompt). Leave this terminal (or command window) that contains the root shell open.
4 S-OFF, root and its friends Super-CID, SIM-unlock, engineering hboot, clockwork recovery and root
In the following section we are trying to gain write access to the emmc by power cycling it.
We recommend to install the engineering hboot as part of the gfree procedure.
In the root shell (indicated by the #) that you got in the Temporary root section execute the following commands:
# cd /data/local/tmp
# ./gfree -f -b hboot-eng.img -y recovery.img
# ./root_psn
# sync
Wait a few seconds for the changes to "take".
4.1. Automatic gfree hboot verification
As it is very important that the hboot was installed correctly gfree calculates md5sums of the partition. It will calculate the following 3 checksums
md5sum #1 - checksum of partition 18 before the installation
md5sum #2 - checksum of the hboot image that should be installed
md5sum #3 - checksum of partition 18 after the installation
gfree will check the md5sums and give you a proper success or error message. The messages are explained in detail at gfree-wiki
The messages that you want to see are either:
md5sum #1 == md5sum #2 - the hboot image is already installed -> skipping installation
or
md5sum #3 == md5sum #2 - the hboot image was successfully installed -> OK!
If you get a different error message you should run for help at #G2ROOT on Freenode.
If you got one of the two success messages described above -> You are fine, Reboot your phone by executing the following command in the root shell (indicated by the #):
# reboot
5. Verify the success of gfree
You can verify the success of gfree by using gfree_verify.
Download gfree_verify.zip from gfree_verify_v01.zip (md5sum 8e3535fd720d19fa0aec4eb711b897c4)
Unzip gfree_verify_v01.zip to a place on your PC.
Open a terminal (or command window) on your PC and change the current directory to where the files are on your PC and execute these commands:
$ adb push gfree_verify /data/local/tmp
$ adb shell chmod 755 /data/local/tmp/gfree_verify
$ adb shell
In this shell:
Remark: When you run su for the first time in the adb shell make sure the the screen of the phone is unlocked. Because when you enter the command the Superuser app will show up and ask you if you want to grant superuser access to app Unknown (2000).
Check the Remember check box and click allow.
$ su
# cd /data/local/tmp
# stop ril-daemon
# ./gfree_verify
You should see the following output:
gfree verify_cid returned:
@cid: 11111111
OK
gfree verify_secu_flag returned:
@secu_flag: 0
OK
gfree verify_simlock returned:
@simlock= 00
OK
Start the interface layer again (IN THE ADB SHELL ON YOUR PC):
# start ril-daemon
Did it work? Here's what you're looking for:
@cid: 11111111 <--- this response means you have superCID!
@simlock= 00 <--- this means your simlock is off.
@secu_flag: 0 <--- this means your radio is S-OFF.
6. Backup and cleanup
During the process gfree created backups of the partitions that it changed on your sdcard in /sdcard/
The files are called /sdcard/part7backup-.bin, part18backup-<time>.bin (if you installed hboot) and part21backup-<time>.bin. It is highly recommended that you copy these files to a save location on your PC and keep them!
You can delete the files in /data/local/tmp they are not needed anymore.
7. Next steps
Find a custom rom that you would like to install and install it using the clockwork recovery.
Enjoy the freedom of your phone.
