Hey guys I flashed eng because I was told it was needed to run cyanogen.....after flash I got stuck in boot loop did a recovery of my back up and im back.....but when I tried flashing cyanogen i still got the same error and couldn't flash cyanogen...how could I tell if I have the eng installed or not....?
[EVO 4G Android Development] AyoJake:
im kinda hesitant to do this what would i need to do if im in a bootloader loop.
[EVO 4G Android Development] Karadorde:
Boot into your Bootloader and see what HBoot img you have. If it says .76.2 then you have the engineering bootloader. If it is anything else, well...you get the picture.
[EVO 4G Android Development] Andy S:
The getting stuck in a boot loop is exactly what we've been talking about for awhile in this thread, so read it for potential solutions.

To tell which version of hboot you have, it's on the top of the screen when you boot into the bootloader (power+vol down).
[EVO 4G Android Development] Karadorde:
Restore from a previous Nand backup. Flash a different PC36IMG. Enjoy your brand new $500.00 paper weight. Only kidding. Those of us getting stuck in a bootloader loop haven't had any problems getting out. And the issue only seemed to happen to a select number of people when they flashed just the hboot img alone. If you flash the hboot .76.2 from the OP and get stuck in a bootloader, just flash a different img or backup, and then try some of the other methods in the thread. Should be no sweat.
[EVO 4G Android Development] AyoJake:
so not everyone is getting stuck and if i do get stuck should i just flash the img from the 2.2 root thread and i'll be out of it and fixed?

and if i flash this will i be able to flash other roms besides dc and cm6 or will i have to revert back to the version i have now to flash like fresh roms?
[EVO 4G Android Development] Karadorde:
Not everyone is getting stuck. Most flashed the img from the OP no sweat. When I got stuck I just reflashed the second PC36IMG from the 2.2 root thread and went from there.

If you flash the engineering broader then you can flash any ROM. Since I switched I have flash CM6, Burnt Droid, and several versions of Fresh.

[EVO 4G Android Development] AyoJake:
thanks for the help soooo i flashed it and im in the bootloop so i need to get the img the wipes the phone right?from the 2.2 thread?and is there a way i will be able to make it work?
[EVO 4G Android Development] EnViiDisLoCo:
Ok just checked my Hboot and I am at 7.62.00000...now that's cleared up why can't I boot cyanogen
[EVO 4G Android Development] Karadorde:
Reflash the second PC36IMG from the 2.2 root thread. It will wipe your phone.

[EVO 4G Android Development] AyoJake:
ok well it seems to have worked.after i flashed it it wouldnt let me reboot so i ended up reflashing fresh and deleted the pc36img and then tried flashing cm6 and it worked and has booted so im guessing i was never in bootloop.

could you say if im good or not? thanks for all the help. : )
[EVO 4G Android Development] Karadorde:
Well if it booted and you are currently in the ROM of your choice then you are good. You could still check to see if you have the eng hboot which would help you out down the line if you wanted to flash custom splash screens.
[EVO 4G Android Development] Karadorde:
What problems are you getting? Is it throwing an error somewhere or what?
[EVO 4G Android Development] AyoJake:
lol ok sorry splashscreen?like the image that shows when you boot?

and the hboot i should have is 0.76.200?
[EVO 4G Android Development] Karadorde:
Yes. That's a splashscreen. And that is the correct hboot img. Looking good.

alright thanks for all the help idk what i was to worried about i guess i dont want a shiny brick lol.i guess thats to be expected and if im doing this i understand the risks.: )
[EVO 4G Android Development] Karadorde:
My suggestion? Download ROM Manager from the Market. Install and flash CM6 through that. That's how I did it at least. Should solve some problems.

This worked for me...

I couldn't figure out if I needed to flash the file or what, so I did (holding breath) and it worked. cyanogen is loading now.

thanks to all of you for your work.
[EVO 4G Android Development] Ep3n3wp:
Quick question... Flashing your modified pc36img will this downgrade our keep my pri the same?(currently 1.40)

Also I used regaws root method and flashed the 2.2 rooted with clockwork recovery...

If I flash this modified img will I loose my clockwork recovery or have a different one after flashing?

Last question...

I'm on fresh 3.2 should I wipe before flashing this? (if not will I loose any settings)

Thanks for your time and modified pc36img
[EVO 4G Android Development] Karadorde:
Radio will stay the same because it uses regaw's PC36IMG with all of the updated goodies.

Your recovery shouldn't be effected whatsoever.

No need to wipe but I believe it will revert you back to a bare bones 2.2 so you will have to reflash Fresh 3.2 unfortunately.

PLZ HELP!!!

Okay someone please HELP! myself, like a lot of others are stuck in bootloader, i am using clockwork mod although i have amon_ra on a disk drive on my computer. My problem is, i downloaded the updated PC36IMG file that someone was kind enough to upload and I removed my sdcard and put it in a card reader to transfer the files from my computer because I couldnt do it any other way. So then when i power my phone back on and get to bootloader, i go into recovery, i try to flash from zip but it says my sd card is not mounted. i have went under the partitions menu(i think) to try to mount it but im not having any luck. Can someone please tell me how to get my sd card to mount using clockwork mod?!??! I have been struggling with this for about 5 hours now and its terrifying. Please help me!!!!!! Also, when i get to bootloader it doesnt even read for the PC36IMG file. Did I do something wrong w/ the zipping?
[EVO 4G Android Development] droyal:
**UPDATE**

went back to sd card reader, placed new PC36IMG file on ROOT of sd card and rebooted, bootloader read the img and my phone is now working again THANK GOD!!!! Now, im determined not to give up on this superuser thing, so can someone tell me now what I need to do to flash cm6 properly, or any rom for that matter. I have tried using rom manager but I keep getting error messages for every rom i select. And thoughts??
[EVO 4G Android Development] nomranomra:
Can someone PLEASE give me a hand? Im having some trouble with this and i would really apreciate it of some could help me. I tried flashing the op's image, only to get stuck in the bootloader like other people are reporting. I have no nandroid backups, and i tried flashing another pc26img from the 2.2 root thread and still it boots into the bootloader. To be honest im new to android and i have no idea what im doing. Can someone help?
[EVO 4G Android Development] Karadorde:
Is the PC36IMG on the root of your sdcard? Does it scan and/or find it when you go into your bootloader. Make sure you are in bootloader and not in fastboot.

Sent from my Burnt Droid regaw-rooted EVO.
[EVO 4G Android Development] Karadorde:
Do you have the engineering hboot img successful installed? What error is it giving you? Flashing roms is relatively easy. (very basic guide) Download the ROM of your choice. Place it on your sdcard. Wipe. Flash zip from recovery.

(Edit) Also in response to your post before the one I quoted, you aren't supposed to flash the PC36IMG from recovery. You boot into bootloader, it scans for it, and then you apply it. Sounds like you figured that out. Just wanted to clear this up for other users even though I am sure someone will make that mistake again.

Sent from my Burnt Droid regaw-rooted EVO.
[EVO 4G Android Development] nomranomra:
Thanks for your response, yes the file is on the root of my sd card however im new to this so im not sure if im using the right pc36img. If you could link me to the right one that would be great. Also im not sure about the fastboot thing, when i turn on the phone it says fastboot in red at the top. from there when i click on bootloader, i get the options of fastboot, recovery, clear storage, slinklock, and hboot usb. Can you run me through what im supposed to click on when i have the image on my phone?
[EVO 4G Android Development] Karadorde:
OK, let's see what we can do.

You can make your own PC36IMG (instructions are listed in earlier posts of this thread) or you can use the one that I hosted in an early post although the link might be broken. I am willing to email it to you if you'd like.

Once we decide we have the right image in the right place:

1: Boot the phone into Bootloader. If the phone boots into Fastboot then highlight Bootloader with the volume keys and press power.

2. Wait.

3. The phone should scan for and hopefully find the image. Make sure there is only one PC36IMG on your SD Card.

4. Apply the update when it asks.

I remember when I applied a new PC36IMG to my phone it was kind of screwy. Asked to apply the update: I did. Then it seemed like it scanned again and I had to reapply before it did anything. Bear with it and don't jump the gun. Let the phone do its thing.
[EVO 4G Android Development] lovethyEVO:
Stuck in bootloader and just need commands (fastboot or adb) to delete the old pc36img on the root of sdcard and replace it with a new one.
[EVO 4G Android Development] Karadorde:
Do you have a mini-sd card reader? I don't think you will be able to use ADB while in fastboot and I don't think you can use fastboot commands to push/pull from your sdcard.

EDIT: Do you have Amon_Ra as your recovery? I know you can boot into Recovery and toggle mass storage of your sdcard from there and then edit the contents from your computer. I don't remember if Clockwork has the same feature but it might be worth checking out.
[EVO 4G Android Development] lovethyEVO:
Hoping everything restores correctly right now.

Did "fastboot update PC36IMG.zip" and it got me out of bootloader and back into my barebones 2.2 root. Trying to restore my most current nand now.

Managed to get it working. Not sure how and don't feel like trying to retrace my steps. All this trouble just to be able to flash splash screens. Sheesh.
[EVO 4G Android Development] nomranomra:
If you could email it that would be awsome. Again, thanks for your help :)

time for a new splashhhhhh!

EDIT: guess not... tried to run the following fastboot command:

fastboot flash splash1 evosplash1.rgb565

but i get this in return:

error: cannot load 'evosplash1.rgb565'

any ideas? splash screen from here:

http://xdaforums.com/showthread.php?t=726710
[EVO 4G Android Development] Karadorde:
Where did you download the splash screen to on your computer? Have you navigated to the correct path in your cmd prompt? Sounds like it just can't find the file.

When I flashed one of 12many's screen I:

Downloaded the file.

Placed it in my Tools folder in my sdk.

Pointed my cmd prompt in the right direction: cd C:\android-sdk-windows\tools\

Fastboot command: fastboot flash splash1 evosplash1.rgb565
[EVO 4G Android Development] DaJibbs:
So it appears I need to do this... but... how do I get access to my phone's SD card if I'm stuck in the bootloader?
[EVO 4G Android Development] Karadorde:
Which recovery are you using? I know with Amon_Ra you can toggle mass storage on your SD Card from recovery so that would be an option. I know I was using Clockwork at the time and I don't believe it had that feature. I ended up going to Radioshack and getting a microsd card reader so I could plug my sdcard into my computer and make the neccesary adjustments. LovethyEVO managed to flash the image through fastboot but I was unaware of this method. Proceed at your own risk.
[EVO 4G Android Development] chapinator.2:
The same happened to me so I remembered that i did not WIPE before instating CyanogenMod 6. I went back and WIPE it all and re-install CM6 again and that worked for me great.
[EVO 4G Android Development] xatreyu44x:
Will this work with unrevoked 3.2, since it does unlock nand?

Doesn't matter what method you use to root or unlock nand. It works all the same.

don't wanna wipe

I've read every message on this thread multiple times. It appears that method here wipes the phone.

Is there anyway to get the eng-boot without a a wipe.

In other words, just update this or flash that & everything remains totally unchanged period, except the eng-hoot is now 7.62.

No having to reload anything???
[EVO 4G Android Development] Karadorde:
Still trying to do some testing on that. No one knows for sure. Next time I am ready for a new ROM I am going to try a few things and I will get back to you.

One question though, why are you wanting the engineering bootloader? Just asking because a lot of people are wanting it so they can flash CM6 and of course any time you flash a new rom you have to wipe anyway.

Thank you for reading through the thread before posting!
[EVO 4G Android Development] lovethyEVO:
ENG boot is also needed just to be able to change the splash screen and not only just for flashing cm6.
[EVO 4G Android Development] Karadorde:
Haha yea I know. That is what brought me to this thread in the first place. Give me a little more credit than that lol. Just trying to save him some time and help him out if I could.

Sent from my Burnt Droid regaw-rooted EVO.
[EVO 4G Android Development] lovethyEVO:
Well then no worries. If you havent changed to the eng boot yet I would suggest making a nand backup first, then flashing the boot as part of an entire pc36img file (instructions are on the first couple of pages) then doing an advanced restore and restore only the system from your nand. Worst case scenario is you get the eng boot loaded but you lose your nand backup because the nand cant overwrite the eng boot from the backup if that makes sense.
[EVO 4G Android Development] rrascal:
thank u 4 responding

I would maybe like to try cm6. Now using stock rooted 2.2. Because I am new to all this I need more confidence b4 that & 4 splash screens.

Eng-hoot seems to be the ticket to not have any trouble with any of these custom roms, so I figure load it and don't worry.

Lastly, I rooted (test revoked method) and flashed stock rooted2.2 with a custom kernel and lost nothing. Every is running and working like a champ. Just trying to avoid the whole reload thing - u know lol.

Thanks again.

can i download PC36IMG.zip from here t instead from this page http://xdaforums.com/showthread.php?t=765496

when i want root Evo?
[EVO 4G Android Development] Karadorde:
I am assuming you are asking if you can use the modified engineering PC36IMG instead of the final one from the 2.2 root thread when you actually root your EVO? Personally I would follow everything as stated in that thread to ensure everything went according to plan. Then move on from there. However, there is technically no reason why you couldn't use this one in place of the final one.

I said 91 just because of the file that was hosted there. There was a lot more information in that post that didn't necessarily pertain to you. Sorry about that. I will PM you here in a second.
[EVO 4G Android Development] cadbomb:
This happens because of the .76.2000 hboot. I too had this problem. I started off back in July using Toast's method to root and had the .76.2000 hboot for the longest time. I decided to try out the new UR3.2 method to root, so I ran the RUU and got back to full stock. After getting everything reconfigured, I made a nand backup So I had the s-off enabled on the .93 hboot and used it for a couple of days. Just for testing sake, decided to go back to the .76.2000 by using this method, which worked great. I made a nand backup prior to downgrading hboot to the eng hboot and I was able to get CM6 installed. However, I decided to go back to my original stock root after a couple of days. As luck would have it, when trying to nand back to my stock root from the .93, I too got the error with not being able to restore boot. I did try to restore everything through clockwork using advanced restore. The problem was that I couldn't get it to boot. So I flashed kings kernel to get it to boot past the hboot. At that point it would boot, but not get past the HTC EVO screen. The only conclusion I could come up with was that because of whatever differences there are between the hboot versions aside from the extended fastboot commands. I wound up just rebuilding and using appbrain to get all my apps back. So I guess my point is, if you're having problems with this method, just take into consideration that you may not be able to go back to any rom that you backed up while using the .93 s-off hboot.

There is a reason this is the dev forum, and it's not for the faint of heart. The way I see it, if you're prepared to play, be prepared to pay... There's a reason every dev in here has a disclaimer for the things they post. :) I don't recommend doing any of this unless you've researched well into what the potential outcomes may be. I will say that if you're just looking to customize your phone, by all means, use what works for everybody else... but if you want to dig deep into the boot methods and troubleshooting, be prepared to lose. Best bet is to wait until there's a good confirmation about what's what.

@stephenvt2001: I'm not sure if this will work for you, but you could always try running an RUU pc36img.zip and going through the UR3.21 root process again, then try restoring your previous roms and see if that works for you. It may bring you back to where you were. Just an idea and I can't guarantee that it'll work, but it's worth a try if you're comfortable. I'm no dev, just a long long time critical thinking IT guy, so I take no responsibility if you try it out :) Good luck!

EDIT: Sorry if this came across like I was being an ass, I just wanted to make sure that everybody understands that there are no guarantees in dev work. If you run into problems, please download an IRC client (xchat, mirc, whatever your flavor) and hop on freenode (see sticky topics under dev forum) and /join #HTC-EVO for assistance. A good bit of the devs hang out there and a lot of really helpful folks who may have experience with your particular issue. I guess here's good too, but live help is also nice! :)

[EVO 4G Android Development] kinya:
When I tried to run Rom manager it wouldn't let me said I needed to be rooted

1. Unzip your full PC36IMG.zip (I got mine from the second part of regaw's root thread. I know a lot of people from that thread are coming to this one so they can flash CM6 etc...)

2. Remove hboot .93

3. Place hboot 76.2 (The engineering hboot from OP) in place of the former hboot .93

4. Zip everything back up.

Be sure you are zipping the contents (system/recovery/radio/etc) into their own PC36IMG.zip If you send the whole folder to a zipped file you will get all of the necessary items, in a folder, in a zipped folder. The phone won't be able to read this. Highlight everything, send to compressed file, and then rename if need be.

5. Place that newly zipped PC36IMG (with engineering hboot) onto your sdcard.

6. Boot into bootloader. Your phone should scan for the PC36IMG.zip that you just placed onto your sdcard.

7. Apply update.

8. Reboot.

Edit: Here is the PC36IMG that I edited and used for my phone.

PC36IMG with Eng Hboot Img

__________________

That is the steps I took
[EVO 4G Android Development] SITH16:
Ok, I tried this, and I ended up in the bootloader loop like everyone else. Through experimentation I discovered I could get out of the loop by reapplying the PC36IMG.zip again and allowing the phone to fully reboot. The problem was that I could not restore a nand back up afterwards and I lost root. Trying to get root back I reapplied unrEVOked3.2 and this did not work. So, not being able to find a way to get root back any other way, I sent through the step by step 2 part root guide and was able to get my root back, with Amon_Ra 1.8. After this I was able to restore a nand back up. I lost the 0.76.2000 hboot though. I seem to be in a catch 22.

One thing I am thinking is, when this is applied, it overwrites recovery and screws up root. Can you remove all other files except the hboot file from the PC36IMG.zip and run the file? I'm just thinking if we could find a way to run the hboot file by itself, it would get rid of all of the bootloader errors people are having. As it stands right now, I'm gonna try to install the 0.76.2000 hboot until I can find a way to restore afterwards.
