Second, make sure you format your sd card. There is really no reason why you can't root your phone following those directions.
Lastly, happy rooting!

ive already formated the sd card several times ,and i forgot to mention that the phone was hard bricked once i got it unbricked using the jtag method i think there is somthing wrong with the spl or bootloader thats y its not downgrading whenever i try to downgrade to rc29 through bootloader it give me an error "not allow 0028008"
Try a gold card.
If it was my jtag method you whould have had a danger spl and could flash anything and I'm unsure why you are back to the stock spl..
If it was omnia's I have some theories depending on how it was executed.

yea i tried the danger spl and it bricked my phone and then i got it unbricked with the jtag method and now its on the stock rc 33 rom and i cant downgrade it back to rc 29. i can upgrade it to 1.6.
Ok I got my G2 when it first came out. Used the old rage method to get S-OFF and perma root. Now i'm reading people say that they have "real" S-OFF and real permaroot. Do I have to do the "gfree" method now or is my phone good as it is?
I understand that with gfree you can unlock your SIM and you can switch between S-OFF and S-ON.. I'd like to have those functions. How should I go about it? Do I do a factory reset to go back to stock and unroot and then use gfree method or is there a simpler way to do it?
Here's what I have right now:
Stock rom, I NEVER installed any OTA's.
I have Baconbits.
My baseband is: 12.22.60.09bU_26.02.01.15_M2
Kernel: 2.6.32.21-cyanogenmod [email protected]#1
Build #: 1.19.531.1 CL255798 release-keys
Thanks for all the help.
Since you have root and a stock rom installed, just run gfree -- that is ALL you need to do. The advantage, aside from unlocking the radio, is that with the proper s-off, there is some new security for the radio... for unbricking and for being able to withstand accidental OTA updates. A true radio s-off can take an OTA update containing BOTH an SPL and a Radio, and yet s-off remains.

I'm in the same boat as the OP. How do i go about just running gfree?

Well I'm rooted with the old method as well but because I I cant flash cwm 3.x with the gree method. You need the eng hboot so ill stick with the old method until clockwork makes it work with the gfree method.

See the Wiki for details. Assuming you are running a kernel where gfree works (again, see the Wiki on this), you just need a root shell on your phone, copy gfree to your phone (e.g. via adb push), then run gfree with the appropriate options, e.g. "./gfree -f".

Using gfree does not get rid of the engineering hboot (or modify your existing hboot in anyway), so it's safe to do. And even if this was not the case, you can still flash the CWM3 recovery without the engineering hboot, only you'll have to use a different method than fastboot.

thanks for responding. so this will work even though i dont have a stock kernel?
also, as far as OTA's go, you mean that if after i run gfree i will be able to apply the OTA without it unrooting my phone?
thank you

Not sure about Baconbits, check the Wiki for the list of kernels that are known not to work with gfree.
If you apply the OTA after unlocking with gfree, you will still lose root but you won't lose the S-OFF and other stuff from gfree.

ok, i see. so if i loose root would i just have to run gfree again after I install OTA to gain root back?

Not just gfree on its own, but you will need to go through the steps of getting temp root then perm root, which does use gfree as part of it. It's all in the Wiki.

gfree does NOT root your phone. It UNLOCKS RADIO SECURITY -- permanently. You only run it ONCE, you NEVER have to run it again... EVER.
With UNLOCKED RADIO SECURITY, gaining root is TRIVIAL.
What gets root is RAGE or PSNEUTER.

Yeah but gfree is often used as part of the rooting process, so I can see why people associate gfree with rooting.
gfree might be run more than once on a phone as part of the process to lock in root, i.e. to defeat the NAND write protection. Even though it's only needed once to unlock the radio etc, you might run it other times if you need to root a stock ROM and updates to that ROM.
gfree can be used to unlock radio security, but it has other options too. Sorry but I think your reply might confuse more people than it helps.

Help me please! I tried to find my answer, but i'm not sure.
Can be possible use the update.zip without any modification? Or i need change the hboot?
Thank you!

I'm perm rooted! but I lost the ota update cause I was simi-brick how can I get the OTA update? do I have to to a factory reset?
You should get the OTA right away after restarting the phone, I know I did after going back to stock on just Saturday of this week. The first time I connected to the network it said an update was available and it was the OTA.
that hasnt happen and it need to hurry up!! lol
So do a Factory reset?
hiya guys, im kinda in the same boat. Just got the g2 with build 1.22.531.8 and perma rooted it with visionary/rage method. I want to get supercid, sim unlock with gfree. can someone post or direct me to instructions on how to do so? thanks for helping a noob.

How do I know what method was used to root my phone? It's been a really long time since I rooted my phone but don't remember which way I did it. I want to unroot and send it back for replacement so I don't want to screw it up.
To be honest I don't think the phone has been around long enough to not remember the rooting method you used...
Check your hboot version and then post it here.

The hBoot version has little to do with what rooting method one used. You could use root.sh or ./gfree and haven not flashed the engineering screen.
Or you could of done either and flashed the engineering screen.
To the [OP] it is physically impossible for us to tell you what method you used.
either way the simplest way way for you to return back to your stock fashion would be to use the PD15IMG in the bootloader.
How ever if you used ./gfree you'll have to replace a specific file that should be on your SD card, given you didn't delete it. If you don't have that file you can still flash the PD15IMG your "s" will stay off however.
I'm new at this so i got all these noob qustions
First my DHD have built 2.42 with Arabic Regional Support ?
so
Do i need A Gold card ?
How do i know if my phone is S-Off or Not ??
What the best way to S-Off , Radio S-Off or Eng S-Off ?
When i downgrade will i loss my stock ROM ?
or i'll lose it at S-Off or rooting ?
Can i backup my stock ROM before i start rooting?
Rooting can mean radio off or/and eng off. Refer to desire HD development for rooting. Different build requires different ways to root.
Gold card, you will need one if your downgrading a branded phone. Branded phone includes any network locked phones and also unlocked phones. Even if you buy your phone out right from somewhere, there's still a big chance that it was locked previously. You will know when it says incorrect CID when your downgrade in bootloader.
Either radio or eng off allows you to flash any custom ROM, for beginners its recommended to have radio as its easier, while enthusiast have eng off, but most of the time, both. However to flash a radio, the recommended way is to have both off
The question about backing up your current ROM. After you root, go download a recovery app namely ROM manager which lets you back up your current ROM, meaning you can restore your stock ROM anytime you want. Hope that clears up a bit.
Sent from my HTC Desire HD using XDA App
You only need a goldcard if your dhd is network branded.
If you havent done anything to it yet it will have S-on
All the information you need is in the first post of this thread Link
If you downgrade it you will get a clean stock rom, losing all the data you havent backed up eg contacts, apps, app data. Anything on your sd card will be unaffected and you can use mybackup (30 Day Trial/Full Version/Root Version) to backup you data (but not app data because you dont have root).
Root your phone and use the root version (also free) to restore the backup. It restores with one click but the non-root versions need you to confirm each app installation.
First i'd like to thank u for ur reply , its very helpful
So i got this facts now, Correct me if i'm wrong
1- The best is to have both Radio and Eng S-off
2- I only need Gold Card if get incorrect CID
3- Downgrade , S-off and Rooting , wont replace my Stock ROM and i can back it up
Using ROM manager
4- I can backup my Info Using mybackup
Is this information correct ?

That is correct. But if you have to choose between eng off or radio off, radio off is a better choice because it's more permanent. You can still remove it whenever you want

i think downgrading does replace your stock rom, just with another stock rom. but it'll be like a brand new phone out of the box after you downgrade, everything will be wiped.
i did the downgrade using the link posted above, and i didn't realise it would do that. I thought i could downgrade, root, back up, flash rom, restore. turns out i should've backed up before downgrade.

after you have downgraded, you could always do an OTA update. so essentially its still the stock ROM that your phone came with.

If your radio off, no, you don't have to root again. Radio off is one of the most permanent thing you can do to your phone. However you can still radio off anytime you want.
However, if your only eng off, you might have to, depending on what version of bootloader you upgraded to.

Comments on your steps.
1. i havent actually personally tried mybackup. but you do realise restoring apps and data from your stock to a custom ROM is different than restoring it onto a stock RUU, simply because custom ROMs might run slightly different. but by all means, try it. i am sure thats not enough to break your phone. you might have to redownload some of the apps tho.
another interesting thing to add is, gmail syncs your contact your email. after a fresh flash, all you have to do is resync. it doesnt give back your msges tho.
3. format your sdcard to fat32. this is important because larger sd cards default format cant be read by bootloader.
6. rooting can be divided into 2 types, eng-off and radio-off. what your doing here is an eng off procedure. skip step 9 all together.
7. make sure you radio off since you will be updating to OTA. some OTA breaks eng off, but radio off would still remain.
10. you might have to eng off (radio off would remain) again if you do an OTA update. i suggest moving step 6 after step 11
keep us posted on your status. good luck.

6. yup, that guide gives you eng off and proceed to step 7 to radio off. skip 9 since its the same as step 6
10. oops, sorry my bad, i meant move it after 10. but it doesnt matter really, since you have radio off (the permanent one), you can even backup stock ROM before you try to eng off. remember, radio off is also one kind of rooting and its 'permanent'

Looks good. But I can't personally vouch for it since i never use his frevo toolkit before. But from what I can guess it's just automated script to run adb commands. So it should be safe. I say go ahead and enjoy rooting and flashing and tweaking and so on.

Staff follow procedures for downgrade, I performed the root, did s-off, has to generate the GoldCard and applied correctly, now I have 2.2 Froyo routed everything right. Room Manager installed, I tried to install many more roms on the device restarts q always falls on a screen with a red exclamation warning. What remains to be done? What went wrong? I have to update the Froyo 2.2 for Ginger? if so? how? help! Thank you!
I looked all over the place and cant find anything like my situation!
Ok so i called t-mobile and they are sending me a replacement because of the bad screen on my phone. All in all i used a method from CM7 to root my phone. I dont remember what method it was. I remember that i had to downgrade my phone and then root from there.
I am trying to get S-on because i already flashed the PD15IMG and it didnt give me the s-on. it just keeps saying s-off. do i have to have s-on for the excahnge? i already have the phone with the stock rom without root.
PLEASE HELP! thanks!!!!
If you used gfree you can run the script again restore S-ON if you still have the part7 backup files. If you don't have them, there is a thread around here somewhere that has the files with instructions to hex-edit your IMEI.
If you used root.sh, then you simply need to run unroot.sh
Edit: I came to the conclusion that if you looked and couldn't manage to find the gfree thread stickied at the top of the dev section that you would never find the thread about hex-editing part7backup. So here: http://forum.xda-developers.com/showthread.php?t=1195630

THIS IS WHAT I USED!
:sigh: The last set of steps had you use ADB to push gfree to the phone. So yes, you used gfree.
Go to the dev section and look at the gfree guide stickied there. It has steps to unroot and 5000 people asking questions when they run into snags during the process. Read until your eyes bleed, then read some more.

okay i have tried everything i could think of and i still cant figure this out!
the problem is that i flashed the PD15IMG via hboot and it put everything back to stock. now the problem is that S is still off and i need s-on to send it back for a replacement. i have tried re rooting the phone from the guide i posted above but i have had no success CAN ANYONE PLEASE HELP!?
i have the stock rom that is GB but without root or anything i cant even get temp root! please help me!
If your on gingerbread (2.3) you'll have to downgrade back to 2.2.1 before you can run gfree to turn
S-on.
After turning S-on reflash a stock pd15.img and you'll be back to stock.
For more info read the rooting guide in the sticky section. I think its the one by grankin01. Its the one that says check this out even if your rooted.
