[how to] remove your "tampered" banner - HTC Rezound

now that we know rumrunner works on this device(some pointers in this thread),and the process can leave you with a tampered banner in your bootloader,i thot there might be a demand for this. this will legitimately change the flag that causes hboot to display the tampered banner,without the inconvenience of having to run an RUU.
this is NOT a patched or hex edited hboot. this is legintimately restoreing the tampered flag to its "untampered" setting
*you must be s off.
*you must have superuser installed(see this thread if you need help installing superuser)
read this:
this will not work if your s on
the usual disclaimers:
i have tested this my my rezound,but use this info at your own risk. if it melts your phone into a little pile of plastic goo,its not my fault.

request that you do not repack this into any one clicks or tools without permission. i spent a great deal of time comparing before and after hex edits to find this flags location
IF you are an advanced user with adb/fastboot set up and some basic knowlede of the cmd window,you can skip to #2
1)set up adb
-download this file
-install drivers: if you have htc sync installed,you should allready have drivers. if not,you can install htc sync,or install these modified htc drivers from revolutionary (driver mirror)
-unzip your miniadb_v1031.zip file. this is native funtionality in windows 7. you otherwise may need a utility such as "7-zip" to extract,or unzip it. place the unzipped folder onto the root of your C drive on your PC. root means the top level,not inside any folders. so just copy and paste,or drag and drop the folder onto C with everything else that is there. you may want to rename it to "miniadb_m7" since youll be putting some device specific files in here.
-open a command window. on windows 7,click the start bubble in the lower left and type "command" in the search box. xp i believe is similar or the same. doing this should open a small black command window.
-change to your miniadb_m7 directory. type the following at the prompt in your cmd window:
cd c:\miniadb_m7
your command promt should change to "c:miniadb_m7>" provided you: 1)unzipped the miniadb_v1031 zip file,and 2)put the folder on your c drive,and 3)entered the name of the folder correctly ("miniadb_m7" in this case)
-now make sure usb debugging is checked in developer options(you will need to turn it on first),and plug your phone into your PC with a usb cable
-make sure your phone is being recognized- type:
adb devices
if your drivers are installed correctly,this should return your phones serial number. you should hear the "found device" noises when you plug your phone in. if it starts installing drivers,wait for it to finish before typing the adb devices command.
if you get your serial number back,then enter this command:
adb reboot bootloader
this should take your phone to the "fastboot" screen,wich is white with colored letters. this is one mode of your bootloaders interactive modes. at the top youll see fastboot devices as confirmation youre in fastboot.
now enter:
fastboot devices
again,this should return your phones serial number. you should hear the "found device" noises when you plug your phone in. if it starts installing drivers,wait for it to finish before typing the adb devices command.
if you get your serial number back,you can enter the following to boot back to the phones OS:
fastboot reboot
and now,youve installed adb/fastboot and tested youre phones drivers. if at either spot,you have trouble and dont get your serial number back,there is some sort of connection issue. use these steps to troubleshoot:
troubleshooting connectivity issues:
-try a reboot of the PC
-try different usb cables and ports
-dont use a usb hub
-dont use usb 3.0
-make sure nothing capable of comunicating with the phone is enabled and running. htc sync,pdanet,easy tether,and even itunes have all been known to cause issues.
-windows 8 has been known to have issues. try a windows 7 or older machine
failing the above,
-i use these drivers for fastboot and adb(donwload and run as admin): http://downloads.unrevoked.com/HTCDriver3.0.0.007.exe (mirror)
failing that,try manually updating the drivers in the following manner:
-put the phone in fastboot mode(select fastboot from the hboot menu)
-open device manager on the PC
-plug in phone,watch for it to pop up in device manager.
-update drivers with device manager,pointing the wizard to the extracted
driver download folder from above
note that you can check the connectivity of the phone,and make sure drivers are working by in the following manner:
-open cmd window. change to directory containing adb/fastboot utilities
-adb with the phone in the booted OS,usb debug enabled,enter:
adb devices in a cmd window
-fastboot with phone in fastboot,enter:
fastboot devices in cmd window
in either case,a properly connected phone with working drivers installed should report back the phones serial number.

this process,in your cmd window,should look something like this:

rebooting...
finished. total time: 0.037s
c:\miniadb_m7>
2)reset your "tampered flag"
enter the following:
adb devices
adb shell
su (if needed to get a # prompt)
echo -ne '\x00' | dd of=/dev/block/mmcblk0p7 bs=1 seek=4391940
(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 tamered is gone
(yes the pics are of m7. ill try and get some rezound pics up later)

Worked like a charm! Thank you for this. I'm out of thanks for today but I will catch you tomorrow

So... What about on JuopunutBear HBoot? Do I need to flash the stock one first?

The jpbear hboot is ignoring the flag,so the banner isn't displayed.
You will need to be on a stock hboot to witness the banner disappear,but it actually doesn't matter what you're running to reset it.

So this might be a silly question, is there any real reason to do this? It won't make any functional difference to my knowledge.
So other than making the banner go away, is there any beneficial use to doing this?

You would not want to send in the phone for warranty repair with the tampered banner,but running a signed ruu will make it go away as well.
Other than that, there is no real reason. its completely cosmetic,it doesn't affect any functionality. For some folks,its presence really gets under their skin. Personally,I kind of like the tempered banner.
you actually can turn it back on with a similar command

This seems pretty cool!
My only comment is that one need not do all of the fastboot-related driver business, because your command is done using only adb. (Yes, sadly, this is relevant for post-Win 7 versions of Windows, which often can see devices via adb but not fastboot...)
cheers,

I've purposely stayed with windows 7,since phone stuff is 95% of what i use my pc for. you are correct,you don't need fastboot at all for this,after verifying the banner is gone,one can simply manually reboot from the bootloader menu.

So removing the tampered flag is only helpful if you need to turn in your phone for warranty reasons..... However if it still says S-off aren't they still going to know it's been tampered with?

---

Worked great!!!! I know there's not much reason to do this but fun to tinker. Thanks for the step by step instructions. Verified tampered flag removed. See before and after pictures.

Pre-release phones legitmately come s off,so its existance does not imply an otherwise stock,locked and non-tampered phone has been messed with.
Plus,you can turn s on if you want to.

Works like a charm. Thanks!
