[Q] Downgraded bootloader for CM6, need to restore for nandroid

All,
I was running Fresh 3.2 on my evo, rooted via unrevoked3. I wanted to try CM6 which required downgrading the bootloader to .76. Decided to go back to Fresh but I can't do a nandroid restore. I wound up having to go stock and running unrevoked again, bootloader now reads .79 but nandroid still won't restore. I'm thinking I need .93 but not sure.
Any help/thoughts?

Yeah you need to upgrade your bootloader back to the previous version then all will be well.

Any idea where I can find/download the later revision bootloader? I see .76 all over XDA and the web, don't see later versions for download.

i had the same problem last week. you did the right thing, but apparently didn't use the most recent stock RUU. once you reflash that, it should update your bootloader to 0.93. you can then re-root and restore.

I just downgraded my bootloader for cm also. My question is can you flash any other rom without updating the bootloader? Say I wanna flash a fresh rom. Would that work?

What was your original bootloader? 0.93? I believe there was no need to downgrade your bootloader for CM 6.1. I had sort of the same issue and this link helped me, I hope it helps you.

Well dang didn't kno that cm6 wasn't hboot specific. I just went off what he had in his guide. So with that pc36img I just flash in hboot and that will change my hboot to the .96? Will I have to flash a different rom right of way? Also are any other roms specific on what hboot u have? I don't mind setting up my phone again. That's the fun of it. Lol thanks tho for the link and helpfull info.

Yes, put the PC36IMG.zip in the root of your SD card and then just boot into the Bootloader. Accept update and you are good to go. So far on my end, I have flashed many many ROMs and did not have to load a different HBOOT. Good Luck.

How to COMPLETELY unroot EVO to send back to Sprint

How do I COMPLETELY unroot EVO to send back to Sprint
Like s-off s-on plz help

If you rooted using Unrevoked 3.21 there is a thread listed in Android Development explaining the process as well as the needed links to download the needed zip files to turn S-On and the zip file to restore back to Stock Froyo 2.2

Ok but there are still methods in the forum for unrooting just like how you rooted. I would just do a search for them and choose which one you feel is the easiest for you to understand. Also if you are getting another EVO unrevoked 3.21 is as many in here have said easy peasy for rooting.
Good luck

You need to run the RUU.exe found in the Dev section. It will do the trick.

Precisely. It can be found here:
*OFFICIAL* RUU_SuperSonic_S_Sprint_WWE_3.29.651.5_Radio_2.15. 00.09.01_NV_1.77_CNV_rel.
One thing to check first: do you have S-OFF? This would be the case if you ever ran Unrevoked Forever or Unrevoked 3.21. If so, you'll need to flash the Unrevoked Forever S-ON tool from recovery before running the RUU.

Thx guys I never used unrevok just toast methods but how do u check the A-on thing & should it be on or off
Also this 1 guy on this forum said he used the ruu & had s-on/off but Sprint still found out he rooted so should I wipe that ex--- >#366# stuff too?

Reboot into the bootloader (turn phone off, then hold power+volume down until it comes on). Then look at the end of the first line.
If it says SHIP S-ON, you're good.
If it says SHIP S-OFF, you need to run the Unrevoked tool.
If it says ENG S-OFF (which should be the case if you used Toast's method), it is indeterminate.
However, if you never used Unrevoked at all, you shouldn't have to worry about it. You can check after you run the RUU, which will reset it to the SHIP bootloader.
I believe the 3.29 RUU resets everything, including the PRI. Toast's method downgraded the PRI, and it was difficult to get it back before the current update, so this used to be a sure-fire way of telling whether you had rooted. Unless you had a bad Wimax flash and broke your 4G, I *think* you should be OK. But I don't know for sure.

I just unrooted mine last night and it only took me 5 mins, just flash the unrevoked and then do the update on the PC36IMG and thats it.

[Q] Backing up stock HBOOT

My sister-in-law got a Bell Desire Z and she may want my assistance with rooting and S-OFF.
I see that the key instruction to install ENG HBOOT is:
dd if=/sdcard/hbooteng.img of=/dev/block/mmcblk0p18
I'm guessing, then, if I wanted to back up the stock HBOOT first, I could do the following?
dd if=/dev/block/mmcblk0p18 of=/sdcard/hbootstock.img
And then if we later needed to restore stock HBOOT from the backup:
dd if=/sdcard/hbootstock.img of=/dev/block/mmcblk0p18
Did I get the syntax right? I wouldn't want to brick her phone

Yes, thats the way to do it. I also backed up all other 30 partitions just in case
Not sure about the restore though. I mean: It's the right commands and everything, but I'm not sure if it will work. Don't see why not though.

Actually now that I've read about nightmarish situations where G2 owners tried to flash back using PC10IMG.zip after perm root and S-OFF, but the first thing it did was replace stock HBOOT, which subsequently locked them out of the rest of the phone. Yikes. I guess you really have to know what you're doing!

That problem will happen ONLY in the case you are flashing a PC10img.zip different from your original version, or if you are flashing an older version...
That will not happen if you get pc10img.zip from your accurate current version or a newer firmware version

Perma-rooted G2 a while back, do I need to Root it with Gfree??

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.

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.

S-OFF and no root, what do?

Here's the story. Got my original G2, played with it, rooted, s-off, the works. Needed to send it in for a warranty exchange so I unroot, s-on, etc etc, and put gingerbread on it. So I had the pc10img file on my sdcard.
Fast forward, I got my replacement G2, it had Froyo, had it rooted, s-off, the works before the battery was even finished charged (I waited for it to finish before I rebooted of course!) and I loaded up the official MIUI. usb tethering wasn't working so I figured I would download and flash a pershoot kernel! That "bricked" it. Wouldn't boot at all! So I booted it in to recovery (vol down + pwr) forgetting that the official gingerbread pc10img was on the sdcard. I was out and about so I just needed my phone back ASAP, so I went ahead and flashed it. So now I have stock gingerbread, with S-OFF and no way to get root. Is there another pc10img I can flash that is pre-rooted, or am I SOL til someone figures out how to root the latest update?
I'm gonna try gingerbreak after posting since I DO have s-off still...

To my knowledge there is still no temporary exploit for gingerbread that you would need to gain permanent root, sorry. It looks like you might be sol, but since you do have s-off try some of the other exploits like psneuter or gfree and post back. I would be very intrested if the hboot was somehow responsible for keeping the gingerbread g2's from getting root

I'm unsure if HTCs .zip includes a HBOOT update or not...but can you enter HBOOT (power+vol down) and check if it says SHIP S-OFF or ENG S-OFF?

I think that, since you're S-OFF, you'll be able to apply any PC10IMG.zip since it won't check signatures/versions - can someone correct me on this if I'm wrong?

It says SHIP S-OFF. And I was also thinking that since it is S-OFF that I could flash a PC10IMG that was already rooted, but seems almost all roms these days are only clockwork flashable.

Back to semi-square one anyway.
I was able to successfully flash the shipped rom as a PC10IMG which I got here (http://shipped-roms.com/index.php?category=android&model=Vision) and I'm going to say that this is most likely because I am radio s-off.

It is because u were s-off. That was my configuration also so if I flash that official gb PC10IMG I'm still s-off but unrooted. To reroot I simply flash the 1.19 PC10IMG, let it get the 1.22 OTA if I feel like it then psneuter/gfree it all over again.
PS - to anyone else... don't even bother with gingerbreak for that official gb

I would put anything with root on it, just to get cwm. Than do as you normally would. As you may know, things are far easier through recovery.
::edit:: you should be able to find a custom built pc10img zip thingy, somewhere on these forums or from someone.
I'm sure you can easily make your own, and it should work.
Goodluck.
