Best way to unroot.

Hi guys I am looking for the best way to unroot my phone and return everything to the way it was out of the box.
I currently have full root with nand unlocked.
Thanks all.

From the unrevoked website:
How can this be removed or undone if I need to take my phone in for service?
Download the latest ''S-ON'' tool to a temporary location and follow the installation instructions above to run it. Once your phone is S-ON, you may lose root permanently if you install an official update

I would install an official update first (to get rid of root) and then use that tool to re-lock the NAND.
Here's the link. I can't post it since I'm a new user:

not that simple. first, run the s-on tool. then, flash your misc partition with toast's modified mtd-eng.img. finally, flash a stock pc36img.zip. sound all good?

Hmmm..... now I'm even more confused.

use the unrevoked s-on tool. then downlaod this thing. evo4g.me/downloads//count.php?target=evo-root.zip
unzip. put mtd-eng.img on your sdcard, nad adb push (which u need to set up if it isn't already) flash_image to /data/local. type:
adb shell
(make sure screen is on and unlocked) su (accept)
chmod 755 /data/local/flash_image
/data/local/flash_image misc /sdcard/mtd-eng.img
then flash a stock pc36img.zip from hboot.

Ummm...you dont need s on to unroot as i just sent a phone back that i unrooted....all i did was downgrade to an older rooted build then ran the ruu from latest update. That put s on for me and unrooted

When you do a NAND unlock (aka a full root), the bootloader is turned to S-OFF to allow you to flash non-official ROMs, recoveries, etc. The S-ON tool allows you to turn it back to the ON position which is standard for non-developer devices (aka consumer-level). When you first bought your phone, it said S-ON in the bootloader, top right (hold volume-down while turning on your phone). Now it says S-OFF. You need it back in S-ON position to make it look like you were on a stock ROM (as well as putting the stock ROM back on).

I'm in the same boat...
I need to do the same to my Evo. Would it hurt if I just flashed the latest stock RUU instead of messing with s-on s-off utilities etc? It is a newer version than what I have on my phone now.
Thanks,

ah, this is why i refuse to use unrevoked...i rather downgrade to 1.47 and then root my phone using 1.47 methods...lol but when i was on 3.29 (not using unrevoked) all i did was run the official RUU on my computer with my phone plugged in and it unrooted my phone, and gave me s-on and flashed stock recovery.

When I rooted my phone I did not use unrevoked either.
Is this a method that I can use to unroot my phone and return my phone to default?

yea, use the latest ruu or the 3.29 to be on the safe side and it will restore you completely to stock.

DON'T use the latest...
That is if you want to be able to root again afterwards. The latest RUU 3.30.651.2 has not been cracked yet and you will be stuck with stock rom, until a solution is found at least. I did this and now I regret it, use anything 3.29 or below and you will be fine.
Oh... and dont accept any OTA's (over the air updates) while on an older rom or the same thing will happen.

He is right. I figured u wanted to unroot because ur sending back to sprint. If thats not the case then use 3.29 or under. I dont think they have found a root for 3.30....sorry bout that.

Is this not a rooted 3.30?....or am I mistaken?
http://forum.xda-developers.com/showthread.php?t=819838

So the main reason I am wanting to unroot is because I am currently having some issues with mms. ONLY on AOSP roms though, and want to see if I restore my phone back to factory default and then gain root access if my problems will be gone.
So if I run just the 3.29 ruu, then my phone will be back on default? I wont have to worry about the s-on s-off thing?

What's the difference

Been reading through the root guides and notice all the gfree topics. I got perm root using the rage method months ago and was wondering if there were any advantages to the gfree method and if so can I still do the gfree

Yes, you can and should use gfree, see the Wiki for details.
The Wiki also has a good explanation of why the S-OFF you have from the eng hboot is effectively only a "fake" S-OFF, and it is much safer to have the full radio S-OFF via gfree.

So I read the wiki and I see what you mean now between the fake s-off and full s-off.
I too did the rage method months ago and am wondering if there are any advantages of using gfree to get the true s-off, besides the safety issue. I have successfully unrooted my G2 using this method: http://forum.xda-developers.com/showthread.php?t=831398 so I am pretty sure that I will not have any troubles if I need to revert to stock in case of a warranty issue.
If I do end up doing a warranty exchange, I will reroot using gfree, but should I run gfree now regardless?
Also, will doing gfree make this process easier of reverting to stock? From reading the wiki, it doesn't specify if I have permarooted using rage if I need to unroot to do the gfree way or if I can just do it over my currently rooted phone.
Or maybe it did and I just missed it XD
Sorry for the length and barrage of questions, but I don't wanna screw this up!
Also, sorry if I thread jacked, didn't mean to, but I didn't see the point in starting a new thread for the same question, just a bit more detailed in questioning.

I went through the whole wiki and had the same questions you saved me a whole lot of typing.

The advantages are that full radio S-OFF can help you recover from certain conditions. e.g. on the Desire Z, some users flashed the 1.72 OTA update and found then that they couldn't root it. But those who had radio S-OFF were able to downgrade back to 1.34 and root again. Those with the "fake" S-OFF lost their S-OFF because a stock hboot was flashed, and they couldn't downgrade so are currently stuck without root.
If I do end up doing a warranty exchange, I will reroot using gfree, but should I run gfree now regardless?

Yes, I highly recommend that you do.

It doesn't really make any difference to going back to stock. You can undo gfree with certain options to the command (see the Wiki for details). Downgrading with the full radio S-OFF is safer too, because you keep the S-OFF (until you remove it via gfree).

Thank you for the explanation, you sold me on gfree, but I'm not 100% sure on that last part steviewevie. So you are saying that I can run gfree in my current permrooted state with the fake s-off that I have with the hacked hboot? I do not need to unroot first and can just run gfree on top of what I already have?

Ok so I ran gfree and it worked great. I just restored my backup of CM6 that I had and everything looks good.
Now final question, do I have to reflash the hboot now that I have true s-off?
I know flashing hboot is unnecessary, but I do use fastboot flash from time to time.
Also, I downloaded the hboot, but when I do a md5 checksum of the extracted file like it does on the wiki, it says md5sum not found. Any reason as to why?

Start from here:
"gfree version 0.02 and its options
Since the current version 0.02 gfree supports the following options:
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 on|off: turn secu_flag on or off
-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
In the following steps the -f will be used to mimic the behavior of the original gfree version that will do radio S-OFF, Super-CID and simunlock in one go.
If you are only interested in permanent root you only need radio S-OFF and then it is sufficient to use
Code:
# ./gfree -s off
instead of
Code:
# ./gfree -f
in the following commands.
And gfree can now also be used to set radio S-ON by using the "-s on" option and to change the CID back to the original value be using i.e. "-c T-MOB010" if you want or have to go back. In addition since version 0.03 gfree can also be used t just to remove the write protection from the emmc and remove the kernels write filter to the radion partitions by using the "-w" option. This is handy if you want to restore your partition 7 backup.
ON YOUR PC:
Unzip gfree_02.zip to a place on your computer. Navigate to where the files are on your computer, and type:
Code:
$ adb push gfree /data/local
Gfree should now be in your phone at /data/local
ON YOUR PHONE:
You should still have terminal emulator up, at a root prompt from earlier.
Now run:
Code:
# cd /data/local
# chmod 777 gfree
# ./gfree -f
# sync
You now have read-write access to your /system, hboot, and recovery partitions. But you still need to "lock in" root, and give you 'su' access in the future. So just do:
Code:
# /data/local/tmp/root
# sync
Wait a few seconds for the changes to "take".
Now reboot your phone.
Congratulations! You're perma-rooted, radio S-OFF, and should have read-write access to your /system! But more than that, your phone should also be SIM-unlocked, so that you can use a SIM card from any carrier (T-Mobile, AT&T, Vodofone, etc.) See below for more info about that.
At this point you might consider downloading the 'Rom Manager app from the Android market and using it to install the Clockwork recovery and back up via the nandroid "backup" option should things go terribly wrong for you in the next (optional) step.
Also, gfree created a backup of your original partition 7 at /sdcard/part7backup-<time>.bin -- You might consider copying this to a safe location on your computer!"
For those who want to know where this info comes from its here at the HTC Vision Wiki: http://forum.xda-developers.com/wiki/index.php?title=HTC_Vision

Thanks, yeah, I bit the bullet and thankfully started from there.
But now I have a new question.
Do have to reflash the hboot now that I have done the gfree method and now have true s-off instead of the fake s-off and the hacked hboot?
Do you know?

No you dont have to reflash the ENG Hboot, turn your phone off, then volume-down+power and on the first screen with the skateboarding andriod it will tell you on the first line "ENG S-OFF" which means you still have your ENG. Hboot, so you will be able to use fastboot.

Yeah I saw that but I just wanted to double check my assumption. Thank you for your help! I am all set now and worry free!

I just ran an experiment on my phone. Even if you rooted using Rage, gfree will still unlock everything.

I would say yes, you can just flash the pc10img.zip if you have gfree'd your phone with true radio s-off. I have not personally tried it myself, so again this is just my assumption, but found a few other post to agree with this:
Weaseal said:
If my understanding is correct, none of this matters if you did scotty2's gfree app to get S-OFF, since it doesn't muck with the hboot (rather, it modifies the radio config [NOT the radio]). So if you did that method to root/s-off (as opposed to the 'old'/alternate wpthis-eng-hboot method), you should be safe to flash PC10IMG without bricking. Can someone else sanity-check my logic?

You are correct. I think the OP is going to try and get this guide updated when he has the time.
Not sure this needs to be sticky at the moment, perhaps until it's been updated ?
Those who only have the eng hboot and not full radio S-OFF via gfree do need to be aware of this though.

[Q] Uninstalling Clockwork Recovery on G2/Desire Z

Hey guys, I'd like to know how to uninstall clockwork recovery from my T-Mobile G2 in case I need to bring my phone in for repair.
I know this is an FAQ, but the method to do it with each phone seem to vary slightly.
My T-Mobile G2 has the following:
Persoshoot's OC kernel
Stock post-OTA ROM with permroot
S-OFF
Latest Clockwork Recovery
What would be the easiest and most straightforward way to restore clockwork recovery back to stock (without nuking everything else in the process)? I see threads saying to run flash_image and flashing the OTA_bootv2 Recovery, but IIRC that program isn't installed on the stock ROM by default.
Your help would be greatly appreciated!

If you used gfree to permroot and get radio s-off, you can just flash the pc10img.zip and it will take you back to stock completely: recovery, hboot, s-on, kernel, rom, etc.
If you did permroot by way of one of the old methods (visionary, rage, etc) you can still flash over the pc10img.zip, after some modifications. Refer to this thread on how exactly to do this: http://forum.xda-developers.com/showthread.php?t=831398
If you have to do the latter, make sure you follow the instructions to the T so as to not end up with a paperweight.

If you have the eng hboot and you have adb setup on your PC, then you can use fastboot to flash the stock recovery image (which you can extract from the stock PC10IMG.zip.

It never hurts to erase the recovery before you flash a new one... rather than flashing a new one in over top of the old one. Sometimes stuff breaks and thats one reason why.

To get permroot, I initially used an old method, but then unrooted. The unroot method I used is actually what's shown in the post you linked to. After unrooting, I did permrooted the "clean" way (the one that's documented on the wiki) using rage to get temproot, then using gfree to do the rest.
Because I used gfree to permroot, I can simply flash pc10img.zip without any problems right? Without needing to hex-edit the misc.img version number to the previous version number? Can I simply rename it update.zip and the HBOOT bootloader will pick it up, or will I have to flash it from within Clockwork Recovery? Why is it safe to flash pci10img.zip if you used the gfree method?
I didn't install the engineering hboot since the instructions said I didn't really need it unless I was a developer.

Yes, that's right, except it shouldn't be called "update.zip", you want to call it "PC10IMG.zip" and place it on the root (top) folder of your SD card, then go into hboot where it should find it and ask if you want to flash it (give it a few seconds to open the file and check it first).
It is safe if you have full radio S-OFF via gfree, because that bypasses a lot of these checks, e.g. the "version is older" check, and also because when it flashes the stock hboot you will still have S-OFF.

It seems as though the OP has had his question answered but I'm also wondering the same question. I have gotten full root by the rage method. What do I do in my situation to get back to stock recovery while maintaining s-off and root. I actually just want to calibrate my battery and go back to clockwork

Lithium Ion batteries cannot be calibrated. There is no need. They dont have a memory like older battery types did, for example, nickel cadiums.
If at all possible, all you would be doing is retraining your phone with that process, not the battery. It is bad for li-ion batteries to be ran completely empty and it is not recommended if you care about the longevity of the battery.

Thanks for your reply. I was told by someone that flashing your phone while it is plugged in kinda throws the battery off. I have noticed extremely short battery life after making this mistake so I thought it was needed. Would you still recommend doing it train the phone itself tho? I mean, my battery life is ridiculously short. Like six hours and my battery always depletes while I'm asleep.

Easiest Way Back To Stock....

You can verify it by turning off the phone and hold vol down + Power. On the top it should either say S-off or S-on. As for going back to stock it matters what method of prem rooting you did. I know you only need to hex edit if you used Unforgivens method, for rage I don't even know how. As for Gfree method, I was told that it should be fine to flash the PC10IMG.ZIp without fail. Sorry if am not any help

Ok, I have s-off and I believe I did it via gfree. Does flashing PC10IMG.zip change it back to s-on?
EDIT - Looks like I flash the zip, and then follow the steps here:
http://forum.xda-developers.com/wiki/index.php?title=HTC_Vision#radio_S-ON_and_original_CID

Actually, another question. I have my nandroid from right after I rooted it. So it's stock/rooted/cwm.
Can I nandroid back to it and then simply flash PC10IMG.zip to it?
** EDIT **
Restored Nandroid and then flashed the update. Then I used the gfree method from the link a few above to gain temp root and restore my partition. Completely back to stock and locked back to T-Mo.
God, I love Android.

[Q] Un-rooted but still have S-OFF ??

I rooted my phone (using Revolutionary found here: http://www.pocketables.com/2011/08/how-to-gain-s-off-and-then-root-the-latest-gingerbread-ota-for-htc-evo-4g.html) and decided to go back to stock since I'm getting a new phone soon so I followed this guide: http://forum.xda-developers.com/showthread.php?t=780141 to unroot. I tried running the unrevoked zip and it failed with and error of "unsupported radio version." So I proceeded to flash the PC136IMG file (I know - I shouldn't have done this yet) which succeeded, but I still have S-OFF and "unlocked" in my bootloader. Shouldn't it be S-ON to be completely stock? If so, how do I get it back to S-ON now that I am all updated on a stock ROM?
Thanks.

Your phone wasn't rooted with Unrevoked, therefore, that method won't work. Try this guide instead.

Also, S-off and root are not the same thing. Here's a good article that explains the difference.
