[Q] PC36IMG.zip and HBOOT version

I successfully rooted my phone but after trying to get Cyanogen running view ROM Manager, really hosed things.
I HAD made a nandbackup that I had successfully rested to, but doing so now gives an error.
My situation is that when I try to start from scratch, I can't--resetting the phone to factory settings doesn't work either. I've followed the directions here:
How to start over: Fully rooted stock 1.47.651.1 in one shot (no adb!)

and here:

forum.xda-developers.com/showthread.php?t=690762
But the issue seems to be that whenever I get into the Bootloader, the PC36IMG.zip file isn't being found. I've uncompressed it to ensure its not corrupt.
When the boot loader comes up, it's version is HBOOT-0.76.2000, and even though I'm following the directions from the 1st link above, the PC36IMG.zip file just doesn't get found and I'm in an endless world in the bootloader.
How can I figure out what I need to do to get my Evo working again?

Did you make sure you have the PC36IMG.zip is on the root of your sd card?

Also, you can just boot into recovery from hboot and just flash your custom rom again to get out of it.

When I boot into Recovery and get taken to ClockworkMod and try to do a recover of the 1st (funtioning) Nand backup I made, the whole backup restores in ClockworkMod only, but when I reboot, I get sent to the bootloader and can't get out of it--which is my original problem.

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).

Root Obtained **EASY!**: T-Mobile G2 2.3.4 official OTA manual update

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.

I compiled the attached files specifically for this. The ClockworkMod Recovery version is 3.0.2.4, SuperUser version is 2.3.6.1.

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

Kevin

Yes. Just flash the PC10IMG and you have clockwork recovery again. However, you absolutely need SuperCID set while in froyo or this does not work.

Thanks Guys for your help!

This worked flawlessly!!
I admire you so much for figuring this out!!
Thank you so much!

HELP!
sort of noobie here..
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.
Kind Regards,
Kevin

G2 Problems??
Hi, how can i get S-OFF on my g2 since it seems i can not generate a beta key from the revolutionary website cause g2 it's not in the drop down list, don't know what to pick and i want to be able to have my g2 rooted with android 2.3.. can somebody help me please?
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.

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.

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.

[Q] Trying to install Engineering Bootloader

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
Click to expand...
Click to collapse
You should see:
--set_version set. VERSION will be changed to: 1.00.000.0

Then attempt downgrading again.

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?
