Downgrade hboot to eng hboot - EVO 4G General

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.

Replacing 1.33.0006 w/o gold card?

Do you know of a thread that explains how the perfected SPL is protected?
Like what keeps us from flashing say http://rapidshare.com/files/26747561...010-signed.zip
From CM1.4
aside from following the gold card instructions elsewhere and the link i got, i would like to know what keeps me from flashing another SPL from a rooted phone with a recovery image (i understand i can not fastboot boot recovery.img as in the link)
but what mechanism is in place that would let the step 5 fail once you are past step 3 of getting into a recovery image)
Since the guide is a way to do it on a phone that apparently does not have a recovery image you can boot into and "apply any zip" from, in which case perfected SPL would keep you from ever booting the recovery image.
I seem to be missing something because in my simplistic thinking i wonder why not put the update-spl-signed.zip onto sdcard, home+power into cm1.4, apply any zip, reboot, voila.
If the recovery image is doing all the erasing and flashing and SPL itself is not there to protect itself, why not?
What am i missing that it seems so simple?
And gold card or not, i see .1009 and .2010 recommended, which one? coin toss?
Thanks in advance for anyone who can clear this up for me,
Daniel
i used this to bypass perfect spl, beware it says g1 but it worked on my 32b board! i dont guaruntee it will work with ures! I found the link on these forums i suggest you do the same
Mods move this to qna. But regardless simple answer for simple ques. If you used one touch root assuming you did. Bc your making this way to difficult. Yes download the spl amon ra has a list of spls you can download its prob on 2nd 3rd or 4th page. Then pick what spl you want put to root of sd and install in recovery as update.zip or as pick ur update. You really shouldnt need a diff spl from 2006 it already is an eng spl. But 2005 does run hero roms better.
There is a newer version of flashrec than that one.

I still prefer the previous one, coz the new one couldn't flash the cusom recovery rom. It only allows you to download CM1.4 and flash it!

Clockworkmod does not work!!!

I'm really at a stage now where i wanna just throw my htc desire hd at the wall!!!! I am trying to just install a custom firmware, not much to ask considering the mammoth amount of hacking you have to do to even downgrade the firmware. I have done absolutley everything that needs to be done to root this device, i have downgraded the firmware i have rooted it, switched off eng s-off and radio s-off i have full root acess with terminal emulator, i put the update zip on the sd card it says something about installation invalid thats because first time i did not disable radio s-off then it went slightly further but then said some other error i have tried everything, i tried rom manager and selected reboot in recovery mode but now it just makes the phone freeze on the htc boot screen when selecting recovery from the boot menu, can someone please please help, how hard can it be just to install coredroids firmware, why can't it just be as easy as the pd98img firmware
help much apprieciated
clockworkmod recovery works fine. Something has just gone wrong with your installation.
To avoid complications later on, you haven't "switched off ENG S_OFF" you've made made S-ON S-OFF and added ENG S-OFF.
You talk about update.zip, is this for a ROM (CoreDroid?)? Which ROM? Did it tell you to rename it to update.zip? If a ROM then it had nothing to do with Radio S-OFF as you only need that for flashing radio.img files and if it was a radio you were trying to push you should use fastboot not recovery. Are you using the right version of recovery (it's very specific about the version required)?
When everything has been installed correctly and instructions followed it is VERY easy to install coredroid's ROM.
hi thanks for the reply, i just follwed the instructions for installing a custom rom as it asks u to chang it to s-off but the guide also says you need to install the update.zip for clockworkmod to get to choose the custom flash rom you want to use but all i get when i select update.zip from the recovery menu is e:signature verification failed installation aborted
Ok, they don't make it very clear do they?
Have you got ROM Manager installed?
Have you got clockworkmod recovery installed? If so what version is it. If not then use ROM Manager to flash it and flash 2.5.1.3 version (as that what it says).
Get the above. Then let me know.
hi mate its version 4.2.0.2 if i select flash clockworkmod recovery it completly causes the recovery menu in bootloader to just hang on the htc startup screen

Sorry, I meant recovery version but it looks like you still need to do that.
In that case push the recovery.img file (grab from the Coredroid thread) using fastboot.
Normally issues are because people miss things but you've confirmed you have ENG S-OFF, Radio S-OFF and root.
ok i tried running this image file in fastboot from this thread http://android.modaco.com/content/z...led-tft-30-nov-2-5-1-3-clockworkmod-recovery/
its written ok but when i select recovery from bootloader it just hangs on the htc startup screen grrr this is just impossible.
That's not for the desire HD.
Grab a 3.x.x.x version from clockwork 3.0.2.8 thread and try that (you can downgrade easily once we got something working).

id say hit the irc for a faster response from someone who knows and ask them if you can use newkidds 1 zip to get your old hboot back, but keep in mind newkidd now has like 3 ruu files the old one with the .93 hboot and one with the .98 hboot and one with none I think

flashed .exe
I flashed the .exe so i dont have access to clockwork recovery any more, To flash zip files. Probably a big mistake until a perm root solution is found.

You won't be flashing an exe with the ruu program on your computer, it should just return you to 100% old stock

I just need to find one that will revert me back to stock with .93 hboot so i can start over from scratch. The v1 version will not allow this due to being the wrong hboot when it does itks check...

Downgrade to HBOOT from 1.02.0000 to 0.52.0000

Hi, everyone who have been waiting for a way to downgrade their HBOOT so that they can get S-OFF, cause they upgraded to the Official RUU Rom... I think I found a solution for you!
Also give you permanent ClockWork Recovery!
I haven't test it on any other Slide, cause I have only one. So, sorry if it didn't work for you.
Here is what I did, in case you're wondering, I downloaded the Official RUU from HTC Support website, extracted the 'rom.zip' file from Windows Temp folder that it creates, replaced the newer 1.02 HBOOT with 0.52 HBOOT, that I got from 'ESPRIMG.zip' (the Stock rom).
And also replaced the recovery.img with ClockWork Recovery img file.
Then I just renamed the 'rom.zip' file to 'ESPRIMG.zip'
Put it in the root of my memory card, powered off, rebooted into BOOTLOADER, and it detected the file and asked me if I wanted to update, I chose YES, and it went on without a hitch. Next thing I knew, I had 0.52.0000 HBOOT, with permanent ClockWork Recovery(so I dont have to use 'update.zip' anymore), and also the Official Latest 2.15.531.3 unmodified rom, (I like stock Espresso, that's why I bought it ) but you will LOSE ROOT but SuperOneClick method works for me to gain root - http://forum.xda-developers.com/showthread.php?t=803682
Method:
1. Download this 'ESPRIMG.zip' file - http://www.mediafire.com/file/cuemg74en7kk0a3/ESPRIMG.zip
2. copy/paste it to your memory card, in the root, not on any folder.
3. Make sure your card formatted to FAT32 file system, or it won't detect it.
4. Do a Nandroid BACKUP, if you can, cause I don't know if this will work for you. But it will wipe all your data and setting. SO BACKUP!
5. First you need to wipe data and factory setting, and wipe cache and wipe davlik cache (Otherwise it bootlooped for me). So boot into recovery first!
You can do that by going into BOOTLOADER first then selecting Recovery ( for that remove memory card from mobile or else it will start update) or if you have ROM Manager then you can use that to reboot into Recovery, any recovery will do stock or clockwork.
6. Ok, so after Wiping from recovery. PULL battery, then insert back the memory card with ESPRIMG.zip file on it. Reboot into BOOTLOADER, and apply the update.
It should do a reboot automatically to downgrade the HBOOT.
You will see the change if it worked. After applying the update, reboot phone normally.
And if all done correctly, you should have 0.52.0000 HBOOT, and also a permanent ClockWork Recovery. Now you can root by using SuperOneClick method. And also get S-OFF (I didn't need it, cause I have permanent S-OFF! , at least that's how I explain it)
Im guessing it worked for me because I have a factory unlocked S-OFF HBOOT from HTC. Because, to try this out first, I updated my phone via the OFFICIAL RUU from HTC Support Website and it showed S-OFF on my 1.02.0000 HBOOT.
Then I tried this method and it did downgrade my HBOOT and I still had S-OFF without doing the AlphaREV method.
So I guess I have a kind of permanent S-OFF??! :S :?
Hit thanks if it helped.
I am no developer but I am learning
Any feedback would be appreciated.
And yes, my major is CS and I LOVE IT!
any one test this yet?
If i try this and it does not downgrade my HBOOT will my phone be bricked? Will I lose root? I would love to try, but would like a little certainty.....

I don't think that you phone will be bricked, it would just not downgrade it but the HBOOT will remain. Yes you will lose root, but that can be gained easily by SuperOneClick Root Method.
I not certain myself about the brick. Flash at your own risk.

Did it work?
has this worked for anyone?
I'll be trying it once the download finishes for me. I'll update you guys on whether or not it worked for me.
I'm using a full stock phone btw, factory reset and blank sdcard as well. Hopefully this works for me.
UPDATE:
Looks like this was a dud.
I applied the update 3 times to my phone, but my Hboot still didn't downgrade. It's still on 1.02.0000. Also didn't flash the permanent Clockwork Recovery that we were hoping for either.
I'm guessing your permanent s-off is what let you use this successfully. So for anyone who has S-OFF already this would probably work fine.
On the plus side, it didn't brick me =)

Well thanks for the feedback, yes I think its the permanent S-OFF too. So does that mean I have a phone that was permanently UNLOCK my T-mobile or HTC it self for testing purposes? Is there some way to use this to unlock that 1.02.0000 HBOOT?
any updates on how to downgrade?
i need to downgrade my Espresso, i have the latest official t-mobile update.
i have already followed instructions very carefully missing no details.
i have searched everywhere and tried everything. thank you.

Another s-off question

Hi about 10 months ago I rooted my Wildfire with no problems using Turkeys ultimate guide from these forums.
I have got apps to sd, live wallpapers running, and all is good. However my phone is still S-on and the H Boot version is 0.80.0002.
When I was playing around with the settings in SetCPU it informed me that the binary was out of date and to update it, but when i tried it would not update as the phone is still S-on.
My question is can I S-off using Revolutionary as it is already rooted? Obviously I will back up using clockworkmod, but if I s-off the phone are there any obvious advantages apart from being able to update the binary in SetCPU?
Thanks
Are you talking about an outdated Superuser Binary? If so, you can download the latest binary here:
http://tinyurl.com/63tsg9c
And simply flash it in Clockworkmod Recovery. This will give you the updated binary and SetCPU should work fine again.
If you have to get S-OFF, then, you will have to apply the official Froyo RUU and update your HBoot to 1.01.0001 because Revolutionary doesn't support any other HBoots, including 0.80.x. Advantages include a writeable /system partition (Which enables you copy paste stuff in the /system folder on a running handset, one case in point is precisely what you described. This will allow updating of the binary), and the other advantage is enabling of Fastboot commands, which allows you to flash stuff like radio's, recoveries, nandroid backups etc directly to the phone without using Clockworkmod Recovery.
Tl;dr - You will have to completely format your device, install official Froyo, and only then can you obtain S-OFF
And simply flash it in Clockworkmod Recovery.
When you say simply flash it in Clockworkmod recovery, what do you mean? And when you say apply the official Froyo RUU and update the HBoot how can I do that as I am running Wildpuzzle ROM at the moment and it says there are no updates available, so can you explain in simple terms what steps to take?
Thanks
Flash in Clockworkmod Recovery - Same way as you installed your WildPuzzle ROM ZIP file. Turn off phone, start using Vol Down + Power, then navigate to RECOVERY, Press Power Button. Here, select "Install Zip from SDCard", then browse to "Select Zip from SDCard", and select the Zip file I linked above.
This entire process is called "flashing".
If you are still interested in getting S-OFF:
- Download the EXE WWE Froyo 2.22.405.1 RUU from here:
http://shipped-roms.com/index.php?category=android&model=Buzz
- Connect your Wildfire to your PC, run it. It will automatically proceed and perform the required steps.
- If you get s Customer ID 131, you will need to create a Goldcard using your SDCard. This an be done using GoldcardTool. The required steps and download can be found here:
http://android.modaco.com/topic/308798-pc-application-goldcardtool/
IMO, I would not recommend you to go for S-OFF since it doesn't seem you are too much inclined to stuff like these (It is not a necessity. Besides, once /system is writeable, it is a two edged sword. Messing something up there will likely cause your phone to not boot). Further, it breaks certain functions on Sense ROMs which needs an additional fix found here:
http://forum.xda-developers.com/showthread.php?t=1156713
hey man, you could also try the test version of unrevoked 3.2 and run that to s off your phone. it works on your h-boot ( i know as i have the same)
since i am new the forum wont let me post the link, its to sstop spamming :/ just search for unrevoked test 3.2 ( it has to be test 3.2 because the others wont work on the hboot to my knowlege. :/)
just download the program and run it and it should do it with no hassle.
good luck

That's totally incorrect. Rooting with Unrevoked =/= S-OFF. Besides, on the very first line the OP says he has rooted his phone using Unrevoked.
ah, sorry about that i was looking at unrevoked forever :/ just ignore me ........
