I need to get a new phone and i want to return back to stock before i ship it to verizon. Can i flash the RUU and it return everything back where verizon wont charge me? Or is there something elsr i need to do?
Download and flash one of the ota non root roms, should be named PB000IMG.zip. put it on the root of your SD card. Power down your phone, then hold down power and send to boot it up. Install the image and then you're done...I think lol

I just rooted my wife 1.49 S-ON phone. I followed Jcase's engineering bootloader thread. Then I flashed the 1.47 Bootloader from the 1.5 downgrade thread. Then I flashed the RUU. Probably overkill but I now have the 1.47 stock hboot and the OTA rom, as stock as I can get.
I can't seem to find the guide for this. I know it can be done....or am I crazy. I rooted a friends phone this weekend. Tried to use unrevoked but it wouldnt work until I down graded froyo. He's rooted now. But still want to downgrade his hboot. And for the life of me I can't find the guide.

I think maybe this is what you want. It installs the eng hboot and amon ra recovery in one shot. The updated file with ra 1.8 is in post 18 in that thread. There's a guide in the first post. The only thing I can think to add is that you'll want to have a rom on the sd card ready to go. The reason being, it might boot loop after the install (mine did) and the only way I know to get out of it is to flash a new rom (or reflash the current one).
I can't post the link or i would just do that.
In the EVO 4G Android Development section, the post you want is called 'ENG bootloader (0.76 needed for CM6) extended fastboot commands'

Zikronix, I have just downgraded my HBOOT from .97 to 0.76.2000. (In fact done this a couple times both from 2.02 and .97). In case you still need this.. below are the steps.
1. Got my replacement EVO today (hboot .97, 3.29.651 build, 1.71 PRI)
2. Rooted it with this method using default (clockworkmod recovery)
3. Rebooted and flashed Amon_ra recovery (optional.. my preference)
4. Copied the correct Eng hboot file (renamed as PC36IMG.zip) to my sdcard, rebooted to bootloader, Eng hboot zip was flashed, I accepted update, done. Rebooted into recovery.
5. Flashed my favorite root ROM (this is necessary bcos the change on hboot does something funky to your existing rom, so you can only reboot into bootloader ... not sure why, some dev should be able to explain more)
6. Done.
I was wondering if it would be possible to flash a ROM without an S-OFF hboot. The logic is as follows:
The NAND lock is performed by the hboot.
Flashing is performed by the recovery OS.
We can now disable the NAND lock using a kernel module regardless of the hboot.
Could the recovery OS disable the NAND lock and flash a ROM without using an S-OFF hboot?
There are a few reasons against flashing the S-OFF hboot, namely, it's less risky, and easier to revert to factory if a warranty claim needs to be made.
Simple answer NO.
Long answer, you can't flash a custom rom without a custom recovery.
You can't flash a custom recovery without and unlock hboot.
So what ur saying will not work because u will not be able to flash the recovery.
Also no risk if u follow the steps. And reverting is as easy as running pc10img
Also this needs to be move to gen thread

Technically, you can probably use dd to reflash the recovery partition instead of hboot, which would allow you to install custom ROMs because the NAND is always unlocked in recovery.
But nobody is going to do that, and there are catches: even then you still can't write to /system without Android without the hack S-OFF is best.
I agree that S-OFF is best, but there might be people who are reluctant to flash an hboot. I figured ROMs can include the kernel module that disables the lock, so they would be able to write to /system.
If it's easy to restore to factory though, I guess there isn't much point in working around the lock all the time like that. S-OFF it is then.
If I missed it, would it be possible to go S-OFF, flash a custom ROM, then go S-ON again?
ok this is a debate i had going on in dz forum. you can flash clockwork recovery via rom manager and prob dd cmd after running the wpthis.ko. you can also perm root it as we know. it has been done in dz forum.
now i agree with you. at this point you should be able to boot into recovery and flash whatever you want and have perm root. however WP will still be on when booted into andriod which can be good and bad depending on how you look at it. (noobs vs pain in ass). this leaves u 2 options. reboot to recovery for any changes, or run the wpthis.ko make changes, reboot.
that being said. heres the prob with having s-on. if you screw up your phone you have less of a chance fixing it. (currently helping someone in this position).
ot anyone know of stock rom in update.zip format?

That's not true......i'm proof
Would need atleast a recovery which uses test keys or simply ignores them.
With the wpthis.ko u could dd other imgs but not enough for a rom as you can not access the system while you are on it.
If you had an S-off hboot u can atleast fastboot the images without the recovery.
Right?

Hello all.. I am tryin to install the engineering bootloader and the file I need from the wiki page is not there anymore. Does anyone know where I can obtain a true copy of it. I d/l one and its not right, the md5sum was incorrect. It should be md5sum: df4fd77f44993eb05a4732210d2eddc6. Thanks if you can help. Im just trying to be thorough as i am learning all this. I have it rooted with s=off but I want to install eng. bl ....Thanks
**It is for MyTouch 4g**
Use this. Its the eng h-boot and clockworkmod recovery.

I got it from one of the stickies in the dev section.
Also, I have 2 Mt4g. One of the has the bootloader unlocked via HTCdev. I keep trying to flash a Stock 2.2.1 rom to it so I can do the Perma Root method on it. I have a custom rom on it currently, but it has s=on. Now the other one was stock 2.3.4 and I just got finished rooting it, for practice. Now back to the one with the bootloader unlocked by HTC, will traditional methods still work on it? 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.

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?
