This is for people that used either of the leak root methods. The engineering bootloader is an unsecured bootloader, and is better in many ways (google it I am not explaining why). Just say its harder to brick with it.
Before attempting, please check your md5sums.
I want to thank Framework for being my punching back and helping with this. And the desire guy's who's work stuck in my head and gave me this idea (Sorry I forgot who you are!!).
Needed Files:
Original Root Rom - PB00IMG.zip - 63eacc5ede3b179f95dc22d8ef585f94
Custom Misc Image - custom.img - 19de71cf42b3a7992d2660e7980c50bf
Fastboot for linux - 4baca1f80fc9bb31aa75fd3fee2cc36b
Amon's Recovery - 354d30c38c59b442340c8b72aa9f547e
Windows users should have fastboot in the sdk, and mac users I dont have a copy of yours.
lash_image - 16559f2c27d08ff1ddfcaca05fbf10fb
Step 1:
Get follow root tutorials and get amon's recovery installed. If you want to skip installing a new rom after rooting, You can flash EngTools.zip will root your device . If you flash engtools you can skip step 2.
Step 2:
Take a nandroid backup, if you wish as this will wipe your device.
Code:
adb push flash_image /data/local/flash_image
adb shell chmod 777 /data/local/flash_image
Step 3:
Push custom.img to your phone
Code:
adb push custom.img /data/local/custom.img
Custom.img is the misc img for your device, it contains the mainversion. I took one off a rooted phone and hex edited the version to be lower than the original root rom so it will flash.
Step 4:
Copy PB00IMG.zip to your sdcard
Step 5:
Flash custom.img
If you flashed engtools3.zip (http://www.multiupload.com/L97EUYBG3V)
Code:
adb shell flash_image misc /data/local/custom.img
If you pushed flash_image
Code:
adb shell /data/local/flash_image misc /data/local/custom.img
Step 6:
Reboot to Bootloader and flash PB00IMG.zip
Code:
adb reboot bootloader
After the new rom is flashed, you can now use fastboot to flash a recovery image while in the bootloader
Code:
fastboot flash recovery recovery.img

Thank you! This will help the leakers *stay* rooted. Otherwise I imagine some will get the new OTA, lose their recovery image, and have to re-root.
This is perfect...That's been my only headache, however step one confuses me. can I just skip step one?...I already have AmonRa recovery and i use Conap's CELB. And can I do this while in AmonRa recovery or when my phone is on regularly?
Works perfect. Now on s-off.

Yeah, you'll skip step one essentially.
Step 2 and 3, you'll do while the phone is booted up, provided you have USB Debugging on.
Then when you copy the PB00IMG.zip to the SDCard and reboot into bootloader, you'll automatically start installing the PB00IMG.zip file.
Doing this will flash the engineering bootloader and you'll no longer have recovery, which is why we do the last step of flashing recovery.
It's best to make a nandroid backup prior to all of this, that way you can restore your OS exactly how you had it.
Is there any real reason to do this other than ota protection? I tried to google it but found no real reason as long as I had root.

Hi, long time lurker first time poster.
Worked like a champ, thank you for your work! Finally the cursed hboot is gone!
Why can't we just do
fastboot flash hboot hboot.nb0
Does that only work once the you already have the s-off bootloader?
Very long time lurker, new to posting. Just wanted to say thanks to jcase. People like you are the reason the Android community exists. :TU:

I pulled the battery after the first reboot on step 6 (after pressing action when the hboot is updated) and saved having to do a nand restore. I'm pretty sure as long as you pull the battery before the second "ACTION" on the rooted PB000IMG you're safe. If not let me know and I'll delete the info to keep anyone from getting bad ideas.
May motivate those happy with their setup to kill the cursed 1.49 S-ON, of course you may have left it out to prevent bricks...

My wife has been having huge issues with her dialer on all 3 of the 2.1 leaks and the RUU. She just wants to go back to stock so she can take it into Verizon. I stole her phone to root it after I had leak on mine and shee has been complaining ever since.
Can I make a nandroid backup, use this method to get the engineering bootlaoder, and then restore the backup to get back to the RUU rom? From there I should be able to flash the 1.47 hboot through fastboot. I'm just not sure what will happen on the nandroid restore. I looked at one of the backups and the hboot doesn't seem to be a part of it but I wanted to make sure it was safe.
Could we do this then use this
http://htcpedia.com/forum/showthread.php?t=2934
to change the hboot number? or would that be point less?
Stop, listen. Follow my directions, if you fail to follow directions I will no longer help you. Don't PM me and ask. If you screw up ask in the thread.

NOT FOR ROOT USERS
Taken from AndroidPolice: [Tutorial] How To "Un-Root" The HTC ThunderBolt And Return It To Stock. Please check the site out.
One of the most popular questions about rooting the ThunderBolt is how to undo the process and return to stock, which renews your eligibility for customer support. Well, here you go:
Instructions:
Please read the whole tutorial first, and pay attention to every detail. Note that your battery needs to be charged to at least 40% at the beginning of the process, and remember to check the MD5 sums of all downloaded files before diving in. As always, neither Android Police nor Team AndIRC are responsible for any damage this may cause to your phone, and, needless to say, returning to stock means you will no longer be able to use root apps like ShootMe and Titanium Backup.
First, download the following files:
Stock firmware (MD5 sum: 7141f5620f6128af77d50587e341f4b0)
exploits.zip (MD5 sum: 3b359efd76aac456ba7fb0d6972de3af)
Next, push exploits.zip and misc.img.
Code:
adb push misc.img /data/local/
adb push busybox /data/local/
adb shell chmod 777 /data/local/busybox
To gain root and flash misc.img:
Code:
adb shell
su
/data/local/busybox md5sum /data/local/misc.img
If the output is anything other than "c88dd947eb3b36eec90503a3525ae0de," stop and start over again.
Now let’s write misc.img:
Code:
dd if=/data/local/misc.img of=/dev/block/mmcblk0p17
Rename "PG05IMG_Mecha_VERIZON_WWE_1.12.605.6_Radio_1.16.00.0223r_NV_8k_1.41_9k_1.64_
release_174685_signed.zip" to "PG05IMG.zip" before placing it on your SD card.
Finally, reboot into bootloader mode by entering the following command. Allow the stock firmware to flash.
Code:
adb reboot bootloader
You’re done – your phone should now be stock, S-ON.
Bookmarking this, just in case. Thanks, Jcase!
Looks like I'll be going back to Froyo for now. I believe the Sense in GB leak is older than the stock on the device.. plus.. camera doesn't work, weather in clock widget doesn't work.. quadrant score is pretty low.. As for now.. I don't see any solid reason to upgrade to GB.. (though I wish I did).. sigh!

First of all Jcase, thanks for the time, I know it's valuable to the community.
So just so I'm clear.... All I need to do is remove "hboot_7630_1.04.0000_110223.nb0" from the pre ota ruu or is there more to be altered than just that?
And if that's all I have to do is flash those seperate, could you tell me briefly why you could not just flash all at once? Would it not flash the rest of it if the stock hboot was installed first?

Yes, because some radios seem to cause the files to flash in different orders, doing it like this keeps me from having to make multiple versions.

Question I have used the oneclick program to get ride of the NV recovery but I think im still rooted because I still see my superuser program on my stock 2.2. Can I just download Rom Manager and use clockwork Recovery to flash the Zips? I have to stock recover now which just formats the phone pretty much.

You need to consult the author of the program, because I don't know what it did, I can't support their application.

Can I still use these steps to revert to stock after flashing the leaked Gingerbread Radio?
i am rooted and so i followed directions for first file and lost root.. so for the second file(its been forever since rooting) do i run adb commands( like step 6 for rooting) for install or can i use fastboot and bootloader? Does the second file bring root back?

if you are S-off, you can just flash the MR1 upgrade from the root guide, otherwise you have to do a complete re-root.
For those of you wondering why the S-OFF feature was worth your extra time to update, this is a prime example of why S-OFF kicks royal behind.
So here is the situation I was having. Friday morning, T-Mo showed me some love and sent me the Gingerbread update. I didn't have my morning coffee so I wasn't thinking strait and authorized the update. I forgot that it would probably interfere with good ol' ClockworkMod Recovery. Sure enough, it did. So, after the OTA failed due to the recovery, I haven't been able to get T-Mo to show me some OTA love again.
However, I had previously invoked the S-OFF feature when it was discovered how to.
After following the guide at http://forum.xda-developers.com/showthread.php?t=1202060 I found myself with a G2 using stock recovery and bone stock Gingerbread (S-OFF still invoked).
After some thought, I decided to do the following:
Flash ClockworkMod via the bootloader screen, and flash SU via the ClockworkMod screen.
Note: You can only do this if you have S-OFF! And since my guide writing skills are not so pristine, I'm assuming you have some sort of working adb/bootloader/recovery knowledge.
Save the attached files (PC10IMG.zip & su.zip) to your sdcard. Reboot into the bootloader either by using the adb command adb reboot bootloader or by powering off, and then holding Vol-Down+Power.
The bootloader will scan for PC10IMG.zip and then ask you if you want to flash the recovery. Yes! You do!
After this, reboot the phone. Reboot into recovery by using the adb command adb reboot recovery, or booting back into the bootloader and navigating to the Recovery console (if you didn't delete the PC10IMG.zip, bootloader will scan it, but don't let it update again, this is redundant).
Once you are in ClockworkMod, navigate to "install zip from sdcard", then to "choose zip from zip card". Select the su.zip file from the list, and authorize the recovery console to flash the zip. Reboot the phone.
Now, you will see the coveted SuperUser app in your drawer. I figured this was wayyyy to easy to have worked, so I tested some root dependent apps, they work flawlessly. I also used the adb command adb shell followed by su once in the shell. SuperUser requested my permission and after granting it, I am able to remove the bloatware that was replaced during the downgrade, also, rebooting the phone as normal and from a removed battery does not remove this root. So I'll say it's a permaroot.
I compiled the attached files specifically for this. The ClockworkMod Recovery version is 3.0.2.4, SuperUser version is 2.3.6.1.
Thanks!
It sounds like you started where I am: Clockwork Mod, S-OFF and stock Froyo 2.2.
Q. How did you follow the steps in the thread to get onto Gingerbread? Did you remove ClockworkMod? If yes, how did you revert to stock recovery? This is the step that I'm caught on, and can't find a thread regarding. Thanks!
Edit to add:
Did you unroot the phone using these steps?
If so, were you at all scared about the warning regarding PC10IMG.zip?
I ended up using the entire stock 2.2 PC10IMG which wiped clockwork off the phone to stock recovery. I didn't do anything to unroot, since the stock rom replaced recovery, system etc but left s-offf in tact.
ETA: I also didn't read either of those articles and wasn't aware of the bricking issue, I've done the phone flashing, modding and unbricking for about 2 years now and just used experience as a guide..

Okay, so just to verify, you flashed CWM recovery while running the GB update? When you adb shell you open a # prompt? I've been gfree s-off'd since I got my phone so even with the leak or otherwise I've been able to just reflash the stock 1.19/1.22OTA and reroot it but I didn't think to try flashing cwm while it's stock gb'd....so tempted.

So I sit down to write up a quick guide this morning and what do I find? Nicely done. Couple of points I wanted to add to why this works -
This method fixes the things that the OTA breaks for root: New stock hboot and stock recovery are flashed and on the rom side it wipes /system/xbin which breaks the su symlink.
Flashing the PC10IMG above fixes the recovery.
Flashing the superuser package reinstalls Superuser.apk, the su binary and fixes the symlink to xbin.
But, still not hboot-eng so your fastboot options are limited.
When I did this I had replaced the DZ engineering hboot.img in rmk's package with the G2 engineering hboot.img and edited android.txt for the new G2 build. This allows you to take care of both in once flash.
Hope this is useful to someone and thank you for saving me from writing a guide!
8/27/2011 Edit:
Realized ro.secure=0 so I repacked the stock boot.img from the 2.3.4 PC10IMG.zip with the below changes to default.prop. This allows use of the "adb remount" so files can be pushed to system folders without needing to go into terminal and mounting rw.
Code:
#
# ADDITIONAL_DEFAULT_PROPERTIES
#
ro.secure=0
ro.allow.mock.location=1
ro.debuggable=1
persist.service.adb.enable=1
Modified installation instructions for full root:
Flash the PC10IMG.zip with the G2 engineering bootloader in this post
Flash the superuser update.zip in the OP
Extract the attached boot.img to the platform-tools directory
Remove the PC10IMG from your sdcard and reboot into bootloader
Select fastboot
Enter the following command in terminal or cmd:
Code:
fastboot flash boot boot.img
fastboot reboot

so i just updated my g2 to 2.3.4 following http://forum.xda-developers.com/showthread.php?t=1202060
and now i want to perm root my phone and overclock it but im having troubles.
1. how do i get clockworkmod installed? i know you can install this from rom manager but it requires root. right?
cause you said.. "Just flash the PC10IMG and you have clockwork recovery again"..
i tried flashing the PC10IMG.zip but got an error and says aborted.
any help please?
thanks in advance
If you are already on 2.3.4 and had not previously rooted then this thread will be of no use to you since your G2 does not have SuperCID (again, read the wiki.)
You will need to downgrade back to froyo (other threads on this and links in the wiki.) Once rooted, then install one of the rooted stock roms in this forum or follow this guide to reinstall the recovery and superuser (hboot optional.)
Hope that gets you going in the right direction.

Thanks.
Revolutionary is not available for the Desire Z/G2. Have you flashed the leaked 2.3.3 and trying to root? PM please.
Hey I notice most of the people in this thread are Americans - would this method work for the DZ or is it just for the G2?
Sorry if this is a noobish question.
Not a noob question, this one is new for me too. Fundementals are the same, process would be the same. I don't know if there is any issue using a PC10IMG with the info for a G2 (contained in the file called android-info) so may need rebuild one modified with DZ information.
Proceed with caution and do not do anything you are not 100% sure about.

I'll hold off on confirming the update in that case! I'm still on stock firmware, didn't apply the update from March either. When I've read enough to be confident on how to perma-root the current firmware I might risk following the method in this thread. Then I'll post back to let you know if it works on the DZ.
My DZ came with 1.34 firmware, I rooted it on this firmware. I accidentally upgraded it and am now on the OTA gingerbread ROM. Is this method suitable in this situation or do I require to flash a rooted stock ROM for this method to work.
Accidentally manually applied the OTA? Should work, you have a G2 now!

Is there any newbie guide for how to do this? From getting Clockwork on there to getting this rooted 2.3.4 on. I have a rooted 2.2 with S-OFF right now, stock. Just don't really know what to do from this point on.
How to is in the OTA thread (which needs a helping of Iron Fist.) Come back here when ready to re-root.

I cant seem to get the adb/fastboot method to install the 2.2.1 rom on it. what would you recommend I do to get s=off on it if Im bent on doing it?

I know NOTHING about the unlocked bootloader, so forgive me. Will flashing the froyo PD15IMG.zip from bootloader not replace your bootloader with the stock S-On bootloader that the rooting w S-Off guides are written for? Or has HTC figured out some way to bone you on that?
PD15IMG method of downgrading should take you to the older OS.
It won't necessarily take you to the older bootloader.
Not sure that being on the older bootloader is required for gfree to work. The older OS is indeed required.
Ok I'll tell you what I did this morning. I read a bunch last night. I am trying desperately to grasp & understand things. Its just there are so many different ways to acheive what I want to accomplish. Im doing this in small goals. My goal at this point is to get this MT4G, that is bootloader unlocked by HTC, to flash the Stock 2.2.1 Rom.But for some reason, it wont. Ive tried using my PC ADB/fastboot method, with no success. This morning I tried Recovery Clockwork, which I did wipe/factory reset, wipe cache, wipe davli cache, and then I choose the write zip from sd card, PD15IMG, and it wont do that either. I know I could be more helpful if I gave the exact errors but I forgot what they are, and at this point I am beginning to think that because its HTCdev unlocked, its not going to let me flash the 2.2.1. It does everything fine, until I attempt to flash the 2.2.1. The md5sum is ok too. If it were you, and you were running a custom ROM (ProjectMIUI 2.2.17 [R6]- UPDATED 2/21/12), and your device was HTC unlocked, but you wanted to get s=off, with engineer boot, how would you begin, and what method would YOU use? Give me some of your excellent advice for my birthday, which is today.
pdimg.zip files are flashed through the bootloader, not recovery. To do this, put zip on root of SD card power off phone hold volume down and power until bootloader appears and follow onscreen prompts.
HTC-Dev-unlocked bootloader 100% allows downgrading, because someone already did it before you. If you fail achieving it - means you're doing something wrong again and again, not realizing it. If I were you, I would think - why is it that your attempts to flash PD15IMG fail - and correct what you're doing wrong. But obviously, this excellent advice was given to you some time before your birthday, and still didn't help.
So, here's another advice:
Go download a PRE-ROOTED 2.2.1-based ROM.
Assuming you find one: flash it in recovery and flash boot.img from it separately.
Reboot to ROM.
Run gfree.
Flash Eng HBOOT.
If you don't find any 2.2.1-based ROM available, then you're out of luck. Sit down and find out what you're doing wrong that doesn't let you downgrade with PD15IMG.
Or just keep your phone as it is, and flash kernels manually, until you understand more.
Ok,I understand what you are saying. But when I put it on the root of my SD card as I have done multiple times, I pwr up in hboot, I wait on the blue progress bar, then a gold progress bar, then I get an error, I think it was "older version" if I remember correctly. There's not much I can do wrong to mess up a simple hboot flash of PD15IMG,you boot your phone up and wait ...

To avoid this error, you need to flash the MISC partition to "fool" the phone into thinking it's older than it is.
Read the downgrading guide, and since you're rooted - execute the "misc_version" part only:
> adb push misc_version /data/local/tmp/misc_version
> adb shell chmod 777 /data/local/tmp/*
> adb shell

If you see "$", it means you're not running in root shell. Then execute "su" and verify that you get "#" to continue.
# cd /data/local/tmp
# ./misc_version -s 1.00.000.0

You should see:

Everything went well until I got to the flashing part again. I did it 2 times, one time with fastboot and i got this:
C:\adb>fastboot-windows oem rebootRUU
... OKAY
From my PC:
C:\adb>fastboot-windows flash zip StockRom.zip
sending 'zip' (319593 KB)... OKAY
writing 'zip'... INFOadopting the signature contained in this image...
INFOzip header checking...
INFOzip info parsing...
FAILED (remote: 99 unknown fail)
From my phone:
The next time, I did it in hboot from the handset and it returned an error that said "wrong zip file"
**I think I am going to be content flashing roms and the boot.img seperately until I find someone with this problem that figures it out. Besides I have another mt4g that I perm rooted s=off, so I truly feel like I have followed instructions well, since my 2nd phone worked out. Its just this one with the HTC unlocked b/l giving me problems.
Thank You for your help...
You insist on NOT following the guide, so I won't help you anymore.
FOLLOW THE DAMN GUIDE UNTIL YOU UNDERSTAND WHAT YOU'RE DOING!
Because obviously, you're doing lots of basically wrong stuff, like trying to flash a PD15IMG.ZIP by fastboot, or using fastboot oem commands.
I understand u getting frustrated, but I have followed the guide. It don't work that way either. It tells me " wrong zip file" in hboot when I do, & I know its the right one because I checked the md5sum. If its lettin me flash any Rom in CWM recovery, why can't I flash a 2.2.1 Rom in recovery? But just to let u know, I have followed the guide to the t, more than once. Sorry if u r getting frustrated but I have tried everything u told me, & thanks for helping.

Good, now that makes it easy as I deleted my modified stock rom last year which I made specially for rooting, so lets move on...
1) Gain TempROOT via VISIONary+
2) On terminal.
adb shell [enter]
su [enter]
dd if=/dev/block/mmcblk0p17 of=/sdcard/msicold.img [enter]
3) Access /sdcard/msicold.img and open it in hex editor.
4) Find MSIC value XXX.XXX.XXX.XXX (ex: 2.09.1800.1) and change it to OTA "1.17.531.2" and save the file as msicnew.img on SDCard.
5) Now back on adb terminal:
dd if=/sdcard/miscnew.img of=/dev/block/mmcblk0p17 [enter]
sync [enter]
6) Now reboot in to bootloader and flash PD15IMG.zip as you would normally do.
Report back if you have issues or problems or can't find it in that case I suggest you upload your msicold.img and ill edit for you so you can replace it.

Ok I did that and opened the msicold.img in hex editor, and honestly I dont have a clue as to what i was doing, but i think i located the value and because i followed the downgrade guide, i beleive its 1.00.000.0, but i dont know how to change it. Any way i can email it to u and have u change it? my email is [email protected] if you will send me a blank email, I'll reply back with the attatched file...Thank you..

Wonder what happened to Anglgodes19 and all his posts? He disappeared like a theif in the night!!
1.00.000 is the correct value.
If bootloader doesn't accept PD15IMG.ZIP - it either means you're doing something wrong even though you're 100% sure you're not, or that HTC-Dev-unlocked HBOOT doesn't accept the image for downgrading, which I highly doubt.
In any case, as I wrote you, you can download and flash any 2.2.1 pre-rooted ROM, if you find one with working link, and continue the guide from there.
I don't think I can help you with anything beyond this point.

Ok then, one last question. If I cannot get my phone to flash via hboot, Is it possible to flash the 2.2.1 rom through CWM like I am flashing other roms? Or if I flash a rooted 2.2.1 rom could I the proceed in getting s-off/ eng hboot? Or does it have to be done through hboot only with a stock rom? Or possibly a modified 2.2.1 rom that has been made to flash in recovery?

Hi all,
Finally received my nexus 4 after suuuch a long wait.
I went the nexus root as I'd really like to learn all the ins and outs of android. I'm working as a web dev now (nothing with java).
This is my first android device and I will soon want to unlock, root and try manually amend system files.
I have some questions though:
1. Can I unlock the phone through the terminal manually and without toolkit? I want to do everything myself.
2. Are there any tutorials on manually rooting a nexus 4 (I saw a gnex). I don't want to use a tool kit for now.
3. I'd like to try start amending (very basic) some System files. Will it be easy to transfer over the code when updates come?
Thanks!

Thanks for the link but I have already read that. What I want to do is manually perform the tasks he mentions. When he says to download a toolkit , I want to skip that and manually do what the toolkit does to have a better understanding of the OS.
Did you actually read it? He gives a step by step from unlocking the bootloader, to installing the drivers needed to run adb/fastboot, root, etc. No toolkit; exactly what you're asking for.

Yes I have. I guess I must of misunderstood what platform tools are.
Why do I need those? The android development bridge cannot work without that?
Platform-tools-v16 contains the files needed to run adb and fastboot. Adb (android debug bridge) allows you to communicate with your device from your pc. Fastboot allows you to update the flash file system. You will need this if you don't already have the sdk installed. Just follow the instructions and it'll be a good learning experience. Good luck.
**edit** I'm not on my system with the sdk, so I can't check, but I don't think fastboot is included with the sdk anymore, only adb is.

its the same as on the gnex, exactly. its the same on all nexus devices. fastboot oem unlock, fastboot a custom recovery, flash either a custom rom or the su binaries in that new recovery, then reboot and profit

OK thanks that clears another point up. I'm not really after learning how to flash etc but more about the OS as a whole. Would also like to slowly attempt to amend some changes in the system files but I'll go ahead and do that guide.

Can you guys answe my other question? What about people who amend the files how so they go about updating the system where. Updates are released?

Make a backup of whatever file you are modifying and when there is an update, revert back to the old file and you should be able to flash the OTA. Or just flash the stock image using the instructions from my first reply, then flash the OTA.
Androidrootz.com has tutorials for manual or tool kits rooting via windows or Mac. I did the Mac version and it was a piece of cake and I am no pc expert. They have info for unrooting and flashing clockwork mod recovery.
Good luck,

Ok that should sort out the updating but after updated what do I do with the backup/modified file. I will have to remodify everything again correct?

Thanks I saw this tutorial and video although I found a better one. Like I said before I thought this was the plug n

there's another guide in this forum, maybe you like that one

OK guys just backed up all my data to my computer. I've downloaded the platform tools but there seems to be a contradiction here.
Do I have to download the .IMG file that is 300+ mb?
cause some tutorials say I don't.
The IMG file is for just in case you goof up and need to get your phone back up and running.

OK thanks. Now I get it.
Regarding the updates, if I am unlocked and have root access with no other changes, I can successfully install the update correct?
Only thing I will lose is root access?
What will happen if I do a factory data reset on a unlocked + rooted device?

What about if I've flashed cwm recovery? To the boot loader. Would that get overwritten
Or is that not affected since its in the bootloader...before you get to the os.

It will not erase that as you said unless you flash back to the stock recovery image as the boot and recovery is separate. You can wipe data and reflash all day long if you want.
