[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] 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...

Trouble (accidentally locked dev edition device)

I accidentally locked the bootloader on my developer edition one M8. I was returning it to stock for a warranty exchange (I already have the replacement device and I need to ship the old one back within the next few days).
I need to get this thing back to stock ASAP
Right now my bootloader is locked (laugh all you want. I'm an idiot.) but I'm S-OFF. Where do I go from here? I need to make sure I'm S-ON and have the tampered flag removed before I send it back, otherwise I'm sure they will bill me for a replacement motherboard and not allow me to have any say in that.

This is basically what I need to undo (I was in a hurry and copy/pasted the wrong text from a tutorial)
adb shell
su
echo -ne '\x00\x00\x00\x00' | dd of=/dev/block/mmcblk0p2 bs=1 seek=33796
exit
exit

Code:
to UNLOCK your bootloader,enter the following:
adb devices
adb shell
su (if needed to get a # prompt)
echo -ne "HTCU" | dd of=/dev/block/mmcblk0p2 bs=1 seek=33796
(i would very strongly recomend you copy/paste this)
exit
(exit a second time if you need to to get back to a normal > prompt)
adb reboot bootloader
verify you are now unlocked

Thanks a million! It worked like a charm!

Reset Warning Flags for E9+

Hello all,
Please help me to reset warning flags for my E9+, in order to send it to HTC. My battery is overheating and the phones turns off, despite the fact it is not warm outside. I presume a temperature sensor is not functioning correctly or a faulty battery cell...
I have S-off, I changed the SuperCID in HTC__621, the original one, I flashed the proper TW RUU, but I need the commands to get rid of "UNLOCKED" and "Status software:Modified" things...
I found the adb commands for M8, M9, M7, but not for E9+...
Can somebody share these to me, please?
Thanks

After a sleepless night, I found the command on a chinese forum. I share it with you now:
adb shell
su
echo -ne '\x00' | dd of=/dev/block/mmcblk0p11 bs=1 seek=39940
Worked perfect for me! I'm back to status "official"!
And for locking/unlocking bootloader (not tested yet) :
adb shell
su
Locked
echo -ne '\x00\x00\x00\x00' | dd of=/dev/block/mmcblk0p9 bs=1 seek=33796
Unlock
echo -ne 'HTCU' | dd of=/dev/block/mmcblk0p9 bs=1 seek=33796
Relock
echo -ne 'HTCL' | dd of=/dev/block/mmcblk0p9 bs=1 seek=33796
