[Q] Undo old permaroot & S-OFF from pre-gfree, or update to new S-OFF?

Hi guys,
I've been reading through the forums over the past two days but I have to admit it's hard to find what I am looking for now that the G2 forum and the DZ forum are merged, and the search isn't getting me anywhere for this one.
I have Bell Canada Desire Z permarooted and S-OFF'd, with CWMod. I did this before the newer gfree method and from what I can gather this can lead me to some kind of endless loop if I try to flash back to the a Bell RUU or other RUUs for that matter. It also worries me that I can't try new radios, etc.
I am getting very poor battery life compared to others so I want to have my phone replaced. I have an extended warranty from FutureShop so I probably don't even need to reset the phone to stock again (they swap on the spot) but I would like to anyway. It will also allow me to test the battery again with the stock ROM.
So, how do I go about flashing back to the Bell ROM and turning S-ON, and unrooting? Keeping in mind that I used the pre-gfree method. I believe it was Visionary R12 and gtab's guide.
Also as the title implies, I was wondering if it's possible to use the new (better) S-OFF even if I am already S-OFF'd the old way?
Any help is appreciated!

You can use gfree and achieve "real" S-OFF without having to unroot.
Just run it. Worst that'll happen is it fails if you happen to be on a kernel it doesn't like. If this happens, no harm is done, just a reboot.

Just run gfree from where you are, as the previous poster said.
That will put you in a much safer position, where you can get stuck in that boot loop that you can if you've only got the eng hboot.
Then you can flash whichever ROM you want. Then you can undo gfree if you want via its new options (see the Wiki).
Regarding your point about the merger, IMHO this issue isn't anything to do with the DZ specifically, and lots of users are posting about similar stuff with their G2s. It's all the same

Thanks guys,
I've done gfree (which is MUCH easier than the thread and wiki make it look - they need to simplify the text, it's overwhelming to look at given how simple the procedure is) and flashed the Bell RUU.
Now I am just about to root, and use gfree to undo the S-OFF I guess?
Will let you know how that turns out. Thanks again!

Ok,there is a new gfree method to get root and S-Off.
And gfree can now also be used to set radio S-ON.
But what about the backup "part7backup-1291675121.bin"
which gfree created at my sdcard?
No longer needed?
And with the new root and S-Off method,is it now possible to
to flash stock RUU 1.34.405.5 to get all original?
Because with old UBERROOT method this doesn`t work!

I'd keep that backup file as it is a dump of your original partition 7 before gfree mods it. You can dd i back and put everything back to how it was, if you ever need to. Do you need to keep it on the phone? No.. store it somewhere on your PC.
With the old "fake" S-OFF you would get stuck if you flashed a stock rom because it would overwrite the engineering HBOOT which was the only thing making your phone think it had S-OFF. With gfree method, you have real S-OFF, so this should be fine.
See http://forum.xda-developers.com/showthread.php?t=838484 for details.
tl;dr You should be fine.

Hm,little bit confused!
The backup I need to get original original partition 7
but not to get S-On.
To get S-On I can use the new gfree method,it`s now
possible with this!
I did the old UBERROOT method with real S-Off!
P.S.I read here about this:
http://forum.xda-developers.com/wiki/index.php?title=HTC_Vision#Rooting_the_G2

Not 100% sure I understand the question...but:
You don't need that backup file. If you delete it nothing bad will happen. Paranoid people (like me) would copy it to a safe place, but there's no real need.
You can flash whatever roms you like, including stock ones, as long as you have real, radio (gfree) S-OFF.

Hi guys, thanks for the help! I got it all settled, it was easy.
As I mentioned above, I used gfree to do a true S-OFF, which was easy.
Then I ran Bell's RUU and it worked without any issues. I assume the RUU install also flashes the HTC recovery back to the phone, I didn't check but it must..
A little summary for anyone who needs help in the future..
If you rooted/S-OFF'd using a method older than the current rage/gfree method (the one in the wiki) then you need to redo the S-OFF using gfree.
Steps:
Use gfree -f to S-OFF again
Run the stock RUU file on your pc (you need HTC sync installed for this)
Temproot (first part of the wiki guide) the stock ROM
Use gfree -s on to S-ON your phone
Reboot, and everything should appear like stock (aside from still being sim-unlocked).

Were u sucessful in returning your phone to htc after u did the above?

I didn't have to return it to htc, just to future shop, and it was fine.

Will unrevoked work?

No it doesn't...the unrevoked dev team is working on one.
leenypost was refering to this thread:
[ROOT][GUIDE] HBoot 2.02/2.10 SOFF - Root! The Final Frontier Edition - Upd. 12.21.10

i think they have but im not the one that wants to do it, i cant cuz my other evo got rooted with Simple root so i didnt have to do it the long Way but i dont have that phone anymore. Any takers?

All you need to do is follow the link ICEReaction posted. It's very straightforward.

just downgrade using a stock RUU then use old root methods

im VERY noob wen it comes to cmd, shell cd to etc. and all that i guess the hard part is the Command prompt i can open but wen changing or anything i get path not found etc

This will not work. If your phone is new and came with hboot 2.02 or 2.10 it is a no go. If you have an older EVO you can flash a rom with a lower SW version and then use an RUU that matches that version if you like and then use unrevoked to root... But that's way more work to then get back up to 3.70 than just following the supplied thread.

Thread moved to Q&A.

How to unroot?

What's up! I'm wondering if someone can help me unroot and put back to 100% stock...
I used the rage/gfree method.

That should do the trick.

He doesn't give instructions for gfree, so I'm not sure if this is the correct method.

Ah - apologies.

No worries bro, hopefully someone else can help answer this question for me.

I typed in unroot G2 in bing search and the unlockr site was second one down, this method worked great for me.

I looked it and read it all.
Since I used gfree to obtain s off and super cid/sim unlock, will it work?

I'm not 100% positive on that. I also have a Behold 2 and, it was rooted when I got it.
I had no idea how it was rooted. I used the unlockr site for it too and, it work for it.
To me, the way the instructions are wrote, it sounds like it will work to un-root all methods of the G2 root process.
Hopefully a more experienced person will chime in shortly.

No, those guides will technically remove root since they restore the shipping ROM but will leave you with S-OFF (since you used gfree---if you had only used the engineering HBOOT to obtain S-OFF, the guides would have been fine). Did you take a look at the actual Wiki: http://forum.xda-developers.com/wiki/index.php?title=HTC_Vision#Returning_to_Stock?

Did you use gfree to to obtain S-OFF though? If you used the engineering HBOOT to do it, as I said in my post, those guides would work fine as is. Flashing the shipping ROM with the PC10IMG file will replace the engineering HBOOT with the shipping one (which is S-ON). If you use gfree though, you get true radio S-OFF (the engineering HBOOT is a fake one that tricks the phone into thinking you have S-OFF, thus allowing write access to the system). This is done by modifying partition 7 on the phone. Since this partition contains information specific to your phone, it is normally left untouched by a PC10IMG or RUU. This is why if S-OFF is obtained through gfree, simply replacing the HBOOT with a PC10IMG file won't revert you to S-ON.

Worked perfectly for me. I flashed stock rom, installed PC10IMG.zip and then used gfree to turn s-on and remove sim unlock.

What should I do first if I used gfree to return to stock on my T-Mobile US G2? I also flashed the eng-hboot.
I used this guide http://forum.cyanogenmod.com/topic/14344-how-to-root-a-new-g2/, and I flashed the "PC10IMG-altered.zip" right after I used gfree to get radio s-off.
Edit: I just followed the xda wiki and I didn't run into any problems.

when it says $ adb push gfree /data/local/tmp/ does it move the irregular files or just the file that says gfree. By irregular i mean any files like gfree.c. BTW what command moves the gopt.c and gopt.h files as i see none obvious commands which would in the wiki ?

Follow the wiki exactly,it is a step by step guide,if you are using windows you can cut and paste the commands as well so no need to worry about mistyping.

P.s. what is the difference between normal hboot and engineering hboot ???

Its to do with the partitions and amount of RAM available,you can also use fastboot commands,depends on what ROMs you are wanting to run,anything resource heavy(sense 3 and above) then you will need to flash the engineering hboot to get them to run,everything you need is in the wiki/virtuous,best of luck

I read up, your referring to the DZHBOOT for G2 users for them to be able to use roms for the desire z. I got this off of the cyanogen mod forums:
The ENG hboot is what unlocks NAND protection. Without the NAND unlock, we wouldn't be able to flash ROMs or have custom recovery.
so basically engineering hboot is a hboot with s off

Yes,with the engineering Hboot you have S-Off and can flash anything Radios,Roms,Recoveries

unrooting the DHD

Having spent time looking on here, I cannot seem to find the info I need... I rooted pre-AAHK (by downgrading and using visionary), so am not sure if I would be able to use the Hack Kit to un-root my phone
I realise that running the correct RUU is likely to be the way to go... what about S-Off? As far as I have read, running the RUU does not put your phone back to S-On.
Would someone mind letting me know if this is the correct order to do things:
Downgrade to 1.32 (by running the 1.32 WWE ruu) - Would it be possible to run 1.32 WWE ruu regardless of what my CID currently is? Also, would this give me WWE/unbranded CID?
Temp root with visionary.
Use the S-Off tool to get to S-On. If wanting to return to carrier branded, then you would also be able to change the CID to whichever Carrier ID wanted.
Install RUU of choice, be that branded or non-branded.
I think that's it... if someone could confirm if I've got this right or let me know if I've gone for overkill?
Cheers all!

I suggest you download AAHK and RTFM, it is included in the download.

As I rooted pre-AAHK and I used jkoljo's tool to get both Radio and ENG S-Off and changed my CID to SUPERCID, I was not sure that I would be able to use the hack kit to do the unroot... especially if I want to return my phone to branded... the way that I understand the AAHK would work is that it would put my phone back to unbranded
