extract misc img mtd0? - Nexus One General

Trying to downgrade the hboot and rom on device and have done this on G2 before. There is a way to extract the misc image using dd but not sure if is the same for nexus one but what the commands for this device are.
when I am trying to flash the passimg file says main version is older so won't work without this. any ideas?
Was trying to follow the downgrade hboot thread and the site for making the misc image is down.
any help would be appreciated.

never mind figured it out.
Code:
su
cat /dev/mtd/mtd0 > /sdcard/misc.img
that pulled it and can edit with any hex editor an put in any version then for downgrade

Flash recovery image Droid Eris How To

First of all thanks to Amon_RA for this. I had no part in creating this. I am just providing a how to flash it. There may be an eaiser way but this is what worked for me.
First let me say I am on a Mac. If you are on windows the adb commands should work fine but I can't say how to get adb working for you.
1. download flash_image Here Link updated 3/17/10
2. Open the terminal and copy and paste the following commands.
adb shell [hit enter]
su [hit enter]
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system [hit enter]
3. In a new terminal window (don't close the original one).
adb push flash_image /system/bin [hit enter]
exit [hit enter]
4. Now in the original terminal window
chmod 755 /system/bin/flash_image [hit enter]
5. Now exit all termainl windows and reboot your phone.
6. Download Amon_AR's recovery Here.
7. Mount your phones sd card and drop recovery-RA-eris-v1.6.2.img on to it and eject your phone.
8. Open the Terminal and copy and paste the following commands with the phone connected to your computer.
8. adb shell [hit enter]
9. su [hit enter]
10. flash_image recovery /sdcard/recovery-RA-eris-v1.6.2.img
11. To get into recovery turn off you phone and hold the Volume Up + Power until it boots into recovery.
That's it.
I made an automator script the help all of you having problems getting adb working. Make sure you have the android sdk downloaded and named android-sdk Put it in your home folder and then run this script. Let me know how it works for you.
Disclaimer: I am not responsible for any damage you may do to your phone. I am only providing instructions on what worked for me. This is very beta. Good luck. Enjoy the nandroid goodness.
First link is Dead...........
ooopps Srry my bad, Its up.
You should mention that the chmod command is in the original terminal window. Also, you could do it in one window if you put:
adb remount
adb push bla /bla/bla
at the begining of everything.
adb push flash_image to /system/bin

I don't think there's a "to" in that command either. lol

Thanks. I don't think the "to" is going to work either. I made the corrections.
Just a quick question. What does this boot too. Im new to all this phone stuff. I did the upgrade to 2.1 leaked so just been searching the forum here each day to see if a solution has come about. i just noticed v.1.6.2 in there so was curious as to what this will do.
Will this put the regular android on it or keep it the same, sorry just kinda getting started with android
coupla questions -
For northmendo:
Is the reboot in the middle of this even necessary? ( flash_image won't work right if /system is still mounted rw ?)
For testing567:
Do all the adb shell commands run as root against the 2.1_root install ... or maybe the above could be simplified even more by just running "adb root" first?
For Austinjs0102 (not a question)
This process only applies (at the moment) to phones with "2.1_root" - there isn't a path at present to go from "2.1_leak" to a rooted phone. Assuming that a way to roll back (or get root) for "2.1_leak" eventually is found, then the answer to your question is this: it is a process to apply a custom recovery partition to the phone that include tools that will allow you to perform complete phone backups and restore operations. This can be critical for devs who are experimenting with writing boot or system partitions to their phones - if something goes wrong with their experiments, they can "boot" their phone into recovery mode and restore back to a working configuration. To reiterate, though: this only applies to phones that are already rooted.

Thanks a bunch that helps clear up info.
hopefully the hard working dev's here find a 2.1 leaked fix for us early people, if not then i may need to lose the phone lol.

I am in same boat as you...
Let me start off by saying that I'm not a phone dev. I've done software development for many years, but never messed with the phone.
Can someone explain why we can't just load the 1.5 rooted PB001IMG.ZIP file over our 2.1 leaked handset? Is it a matter of the version number being lower? If so, since the 1.5 is rooted, couldn't someone just up the version number to whatever the 2.1 leak is plus one? Then, once it's loaded, write a little app to drop the number back where it should be?
TIA for the education.

Doc,
I understand exactly what you are getting at... and also think I can explain why it's not easy.
First - what has been discovered so far was not a "root break-in", but rather an engineering ROM with root "built in". It is cryptographically signed so that a production phone will recognize the .zip file as a valid ROM. That first validation step has nothing to do with version numbers.
If the "SPL" on an unrooted phone was doing something as simple as looking at a couple of bytes in the initial file downloaded to the phone, then yes - doing what you suggest would work... just patch a few bytes using a hex editor. Unfortunately, the phone SPL is quite sophisiticated: it verifies the crypto signature on the entire zip file first, unpacks that zip, and then examines the contents of an individual file within the zip archive (and possibly even unpacks one of the YAFFS image files and then looks in a file within the YAFFS image) to read version numbers.
That means that the fundamental issue is the cryptographic signature on the .zip file. If you do anything which breaks step #1, step #2 (version # checks) are never reached. Certainly an individual file could be byte-patched, and then images and zip files could be re-assembled... but you would have no way to sign the zip with HTC's private key. Or you could even attempt to byte-patch the zip file - but then that would break the crypto signature. Either way, the crypto signature on the zip file is no longer valid.
If you have HTC's private RSA key, let us know!

I added the reboot because. All I would get is out of memory errors. The reboot fixed that.
e.g.
mtd: read error at 0x001e0000 (Out of memory)
mtd: read error at 0x00200000 (Out of memory)
mtd: read error at 0x00220000 (Out of memory)
mtd: read error at 0x00240000 (Out of memory)
northmendo -
That first link (that you corrected) now points to the recovery image, not "flash_image".
Note that the "flash_image" executable which Amon_RA originally included with his first recovery (.zip) is identical to the /system/bin/flash_image binary which ships on the Eris with 1.5 (1.17.605.1); the md5sum signature (of both of those files) is:
16559f2c27d08ff1ddfcaca05fbf10fb flash_image
That's also the same md5 signature as the "flash_image" file which was posted to dl.dropbox.
I don't have 2.1_root installed on my phone, but if the same binary is already on the phone after installing the 2.1_root ROM, there's no need to include those steps in your instructions. It is also possible that even if the "2.1_root" version of /system/bin/flash_image is different, it would also work.
Note that the only reason I bring it up is that your instructions might be (a) unnecessary, and (b) are encouraging folks to overwrite a binary that is already on the phone. No harm (but unneeded) if it is the same, and unknown harm if it is different.
Also (while I'm at it)
901167f6b5541b488c8e0404bceb0631 recovery-RA-eris-v1.6.2.img ***
It appears to me ( reading between the lines here ) that Amon_RA is trying to improve his v1.6.2 recovery - folks might want to keep an eye on that thread.
An alternative and quicker method than all of this is what zifnab06 suggested here. It's only two lines long, after all.

[Edit]***Wow, my post was obsolete the moment I posted it - don't know how I missed Amon_RA's announcement post. Note that there appears to be several versions of "v1.6.2" floating around now - make sure to check his post if you want the most recent.

Sorry, didn't mean to. Understood on the explaination. I didn't realize it was a different rom image, I thought the key had been broken, allowing someone to resign a modified image.
Thanks!

I used this method and it was all really easy until I got to the end. It just says usage and then sits their and does nothing. I unplugged it and went into recovery and see the android dude and a yellow traiangle and exclamation point. Did I forget something? Is their an alternative way to flashing this?
sdk issues for flashing recovery...
Hey guys,
Im a noob but here's whats going on, Ive downloaded sdk extracted it to my c drive, ive downloaded all the required packages reccomended in the forum, Ive up dated my driver and still my machine doesnt recognize my phone...
Ive also extracted the recovery image to my tools directory and added the the path in enviromentals...
So at this point Im stuck as to how to get my pc (xp) phone and sdk in sync in order to get this recovery image working...So any advice would be highly appreciated. Thanks in advance.

You could try this.
If you have your phone pluged in and type in to the terminal
adb reboot recovery [hit enter]
After you phone reboots it should come up with text options to do back-ups and restores. Do you get any of that?
Anyone know the key combo to get into recovery without adb?
having issues getting adb
got the command prompts working in xp, however while trying the methods here in the forum i am getting adb not foud errors. Any suggestions?

Flashed a corrupted hboot the phone is DEAD any way to save me from this one?

OK i got a MT4 so i flashed the engineering bootloader, since it wasn't my first mytouch 4, i already had the files in my computer, so somehow my files got corrupted thanks to the new SSD technology, so now i have a phone that won't turn on at ALL.
Any way to recover from this one or the board is tossed? any way to save it with a JTAG?
thx

I don't know of any way to save it through software. You'd need the bootloader in order to use fastboot.
Advice for everyone:
Before you flash that bootloader, verify it by comparing it's md5 checksum to the one provided in grankin's thread. If you can't find it, this is it:
Code:
md5sum: df4fd77f44993eb05a4732210d2eddc6
I check mine at least once before and ALWAYS check after flashing. Here's how:
1. On your computer, after downloading. Mac/Linux users can probably do checksums in terminal. I downloaded a checksum utility for Windows that adds a checksums tab when I right-click >> properties on any file.
2. On the phone with terminal emulator. Assuming you pushed the file to /data/local, open terminal emulator and do this:
Code:
cd /data/local
md5sum hboot_dhd.nb0
If what you get does not match the above, re-download the file.
3. After flashing. You can enter the path of the bootloader as the argument for md5sum. This is ALWAYS a good idea to make sure it was written properly, even if you checked it already in /data/local. The command (in terminal emulator) is this:
Code:
md5sum /dev/block/mmcblk0p18
If what you get does not match the above, DO NOT REBOOT THE PHONE. Re-download the file if you have to and flash again. Only reboot if md5sum matches the above.

Same here. Screen lights up but just blank when power button is pressed. Power + volume down doesn't work. Power +volume up makes the phone vibrate though but I dunno what that means. PC can't detect the unit via USB, tried ADB devices but no success.
Bricked forever? what's the cure??? help?

[Q] how can re-root the offical update?

hi.. after following the instructions on how to downgrade my phone, and obtain root, i have, and after i had my foryo rooted, i downloaded RUU_Vision_Gingerbread_S_HTC_WWE_2.42.405.2 because my original intent was to have a rooted gingerbread and it didn't make much sense to have roms provided by htc itself.
but now i see i don't have root, so oops, i guess i was wrong.
so do i have to go though the whole kaka procedure again, and then find a custom rom, because my end game, is to have as close as possible a rooted gingerbread as close as possible to the original HTC rom. where can i get one?
oh, and what's the difference between the asia and wwe? does any of them handle hebrew bidi writing correctly (without applying the patch?)
I think there is a way to root gingerbread, or you have to downgrade. At either rate, you want to get to a place where you can flash your own ROM. Having clockworkmod installed would be just fine.
Then you would take the stock gingerbread, extract and unzip it, add Superuser and su, make the boot insecure, repack it for flashing, flash via CWM, and presto- rooted stock gingerbread. If you want to build in hebrew bidi writing, you can add that too.
There might be a few rooted stock gingerbread roms out there, but it seems that the trend is toward cooked up versions, rather than stock.
AFAIK i don't there's a way to root gingerbreak, it's un-rootable, that's why i downgraded in the first place. i think i can do it again, question is:
where do i find the stock gingerbread rom? is it in the RUU exe? if so, how get it out from there, without installing it
second, how on earth would i do all the things you said (add su,make boot insecure,repack,flash cwm).
is there a guide out there for all there above?
I think there is a some software for windows that will allow you to extract the rom from the RUU. I don't use windows, so I don't know anything about it. I've seen some posts about it, so I can say it seems to involve using the RUU to almost install the ROM, but at the last minute, just stop and the ROM will be extracted into one of the temp directories. You just use the RUU to extract the rom, not install it.
As far as all those other steps, I think all the information is scattered about xda.
Here's some information about the insecure boot image. It's for the transformer, but it's essentially the same thing, except for the blob parts. You'll have to use something like splitbootimg or bootunpack, and mkbootimg (search for them) instead of blobunpack.

As for the other parts, you can use some of the other updates and zip files as a guide to figure out how to unpack, mod them, and repack them. I think there might be a rom kitchen script that will do this too, but I can't speak to that either.
Sorry if this sounds so complex- it's not that bad once you've done it once. I have a rooted stock GB that I made this way from the GB update, but it's the US version. Let me know when you have the WWE version extracted.
ok, let's take it one step at a time, (maybe we'll make a guide out of it
i activated the but i never continued instead i used process explorer to find out which files it's holds, so i got the temp directory and extracted rom.zip a 260 mg file (containing various img files)
now what?
btw is this relavent? http://android-dls.com/wiki/index.php?title=HOWTO:_Unpack,_Edit,_and_Re-Pack_Boot_Images
yea, i've seen it is, but one issue is that where do i get the cpio and makebootfs, (if i need to compile stuff, this is where i stop, i allready downloaded the perl scripts, as well as GZIP
ok, so far so good.
That link is exactly what you need. You can use that info to unpack the boot.img and make it insecure "ro.secure=0" by editing the default.prop file in the ramdisk.
I think some of the links to the tools might not work, but these will work instead - https://github.com/AndroidRoot/BootTools
Use the guides to mod and then repack the ramdisk
put the kernel and the modded ramdisk back together with makebootimg. There might be some specific command lines and kernel addresses- the hdrboot tool will show you want they should be from the original boot.img
Also, could you upload the zip file or PM me a link? This would be a perfect project for a guide.
ok wait, which tools am i missing? i have a windows machine (ultimate 7 64 bit) and the boottools needs to be compiled, (i don't have developer studio installed just eclipse)
so far i have the following tools:
repack-bootimg.pl
unpack-bootimg.pl
split-bootimg.pl
cpio for windows
gzip
what zip file?
(i'm going to sleep now as i'm in israel,i will "boot" in 6 hrs, luckily i have a vacation tommorow, so i hope we'll have time to finish this.
I think you might need gunzip to extract the ramdisk. unzip might work, but I'm not sure with Windows.
The zip is the rom.zip which has the rom.
I seem to recall there being at least 2 rooted stock ROMs in the dev forum. I think the one I've used was posted by either suilmagic (may be siulmagic), or rmk40. Xboarder56 posted one some time ago, but he started stripping things out that I used, like QuickOffice. If nothing else, this finally drove me to use Titanium backup...

actually i DID google "rooted stock rom desire z"
but i could find anything for sure, that's why i posted this, is this rom appear in the developer list of roms linked in the downgrade wiki? because i couldn't find it there either, would be nice if it was added.
No worries- I didn't actually search for it- I just paged through some of the dev sections.
I think you'll have flash it using CWM recovery.
great, i'm assuming CWM is Clockwork something?
Yup- look for the 3.x version. There was a 5.x, but i think it has some issues.
ok, so now, i must re-downgrade, root,
http://forum.xda-developers.com/wiki/ClockworkMod_Recovery
get rom manager, and ah... wait, what's the update.zip? is that actual image i need to place on the sdcard?
That wiki seems kinda old- I don't think the stock recovery will flash the update.zip
This is more up to date and specific for the G2/DZ:
http://forum.xda-developers.com/wiki/HTC_Vision#Rooting_the_Vision_.28G2.2FDZ.29_and_DHD
yea i've read that one (that's how i rooted in the first place.
isn't there a way to short ciruit this somehow and instead of pc10img have the update itself installed ? or is it because it's a an OTA, i have to do the whole thing?
looking at the image, i think i'm missing someting it looks like i can somehow use the scripts inside the image when i get temp_root (meaning i won't have to update the original image. am i wrong?
ok i've gone through the motions over and over, finally rooted it, have rom manager, clicked flash recovery, copied the zip file for rom i wanted to the root of sdcard, selected it rom manager, rebooted, now i selected apply update from sdcard,
now i see the hat signal and nothing happens, (i also selected backup rom and wipe cache and data)
i also noticed that i have install zip from sdcard, but i didnt' select it, how long should it take?
ok i FINALLY managed to install (it actually i pressed power button again and immdietly returned the cwm main menu, from then on, i chose reboot, i think it's moved on.
problem is, some things looked odd, for example the phone bar on the buttom, looks distorted, when i click on the application list i can only see half the list (meaning half the screen shows the list although i can scroll up and down the buttom half remains blank..
never mind it's ok now after re-boot..

but it didn't workout so much, don't know why it said something about it couldn't write recovery img file
Umm if you already rooted via the xda wiki then you should've had a bootloader that was engineering s-off right? Just saying because you could've flashed a custom rooted rom through bootloader and not had to re-root, that is unless the ruu applied an updated bootloader with s-on. Maybe boot into bootloader and see if the top line says PVT ENG S-OFF, worth a look anyway, could save you some headache

actually i'm haveing another headache a couple actually, for some reason, during the restore, it failed to download google maps among the gailion apps i downloaded, now i can't download no matter, i tried installing it manually, and it worked, but i can't see in the market.

root 2.3.4,downgrade,and s-off

ATTENTION! this thread is OUTDATED
unrevoked has always been a finicky program,3.22 working fine for some,not so much for others.recent updates seemd to have made it even worse, i see alot of issue and fustration with it lately. as such, i do not recomend this method any longer.
IMO,at this time htcdev is the best way to root,downgrade,and achieve s-off. while it technically does void your warranty,and wipe your data,it has thus far at least proven to be reliable. i doubt may original droid incredibles have factory warranty left anyway it does not use unrevoked,or any otehr root tools or programs,just htcs own unlock(you can giggle loudly,or silently,as you use their unlock to achieve s-off
the original home of the hctdev method is here, on android forums.

READ THIS: i dont mean to sound like i dont want to be bothered with questions. however,folks are having basically the same issues thru-out the 600+ posts,so i can almost gauarntee if you have a prollem,it has been covered. please try and search for some answers before jumping to the end and posting. answering the same things over and over is just making the thread even longer and harder to search.
if you do have trouble and need to post questions about ADB commands,please provide a copy of your entire session in the command window along with the question. its usually pretty easy to see what went wrong when we can see the whole thing.
copy everything in the command window,and paste it into a code box by:
-right click in the command window,click mark.
-highlight everything in white. hit enter.
-then,in your "reply to thread" box here,click the "#" up top
-right click and "paste" everything between the

tags.

i cant take credit for any of this,i just took it all from different places and put it all here. unfortunately,i cant gaurantee that this will work for everyone. but several now have rooted 2.3.4,and 1 has succesfully downgraded and gained s-off.
its intended for someone who has no adb experinece,and is overwhelmed at the thot of downloading and installing the SDK. if your proficient at adb,your welcome to pull flash_image and mtd0 out,and place them in tools,platform tools,or wherever you usually push files from,rather than changing to the mini-adb_inc directory.
thots and feed back are welcome. there will prolly be several edits of this as i try to clarify it,and make it a lil better. but for now im tired and 5am comes early ;)

**make sure to check the md5 sums match those listed!**
if you dont have an md5 sum verifier on your PC,there are many out there for free. heres an example: [url=http://www.md5summer.org/]Home of the MD5summer[/url]
2)[B][I]root with unrevoked 3.22[/I][/B]
-go to settings/applications and [U]uncheck[/U] "fastboot". having this checked will prevent you from getting to hboot via power/vol down.
-open the recovery-clockwork-5.0.2.0-inc_PB31IMG download. extract it first if you need to. inside there is an image called "recovery-clockwork-5.0.2.0-inc". right click on this image,then click "copy". navigate to a directory you can easily find it,then right click in that directory,then "paste". alternatively,you can drag it from the extracted folder to a convienient spot(i personally like to drag files around,but its fine either way).
-use your md5 summer to verify the md5 of just the image,not the whole .zip. it should be: [COLOR="Red"]ea382ca5809cb872d0582aa22741d592[/COLOR]
-install the drivers as described on unrevokeds page above.
-unplug your phone.
-extract the contents of the unrevoked 3.22 .zip. open the folder, right click on "reflash" and run as administrator if possible.
-click on "file" in the corner of the relfash window
-click custom recovery
-navigate to,and select your "recovery-clockwork-5.0.2.0-inc" image and select it. at the bottom of your reflash app window, it should now say "recovery:custom" and "waiting for device"
-make sure usb debugging is checked ON in settings/applications/development.
-plug in your phone and place it in charge only mode. assuming you installed the drivers correctly,unrevoked 3.22 will start. let it do its thing. it will reboot a couple of times. when its finished,it may leave you on a blank screen. if this is the case,pull the battery and reboot.
-you [I]should[/I] now have the superuser app in your app drawer. if so,go to settings/applications/manage apps/superuser and clear data. test that superuser is working and granting permissions by downloading rom manager,and using it to flash the newest clockwork recovery. alternatively,download and run a "root checker" or any of your favorite "root only" apps and make sure they work.
-once you get "successfully flashed clockwork recovery" boot to it and make a backup,since downgrading to get s-off [U]WILL[/U] wipe all your data. boot back into the operating system.
*[I]special note to slcd users[/I]: this version of unrevoked is installig an old, non-compatible version of clockwork,so you will just see a black screen if you do not install newer clockwork as described above.
-if you plan to install a custom rom after downgrading,now is a good time to download titaium backup,and its pro key(WELL worth the $$) and do a batch backup of all your user apps and app data(no system data)
*at this point,you could just enjoy root access without doing anything else. if all you care about is using a couple of root only apps,and deleting some bloatware,you can remain rooted and s-on if youd like. id personally reccomend to downgrade and become s-off in case future OTAs knock out your root access.
3)[B][I]prepare to downgrad[/I]e[/B]
-extract the mini-adb_inc .zip. place the extracted folder on the root of your c drive. it comtains mtd0,flash_image,and some adb tools.
-place the 2.2 downgrade on the root of your sd card,and verify it is named "PB31IMG". now is a good time to verify that your SD card is formatted "FAT32" by right clicking on the drive that is your phones sd card,then click "properties". if you find your card is formated anything else,youll have to re-format it. start by backing up all files to your PC as reformatting [U]WILL[/U] wipe it clean. using your PC,do a full format to FAT32. you can then transfer the files back. *this is important-as your phone will not find the downgrade PB31IMG unless your card is formatted to FAT 32,and the file is correctly named.
[U]special notes on hboot flashing PB31IMG files[/U] a common issue folks are having is the PB31IMG is not being found by hboot.
*there are only 2 reasons a PB31IMG is not found on the root of the sd card:
a)not named correctly. the phone muse see exactly "PB31IMG.zip". due to the way windows automatically adds and hides file extensions,it is usually correct to name the file "PB31IMG" with windows. common errors are for the file to be named "PB31IMG.zip.zip" after manually tying in the ".zip". on rarer occasions,it may not be adding/hiding the file extension,resulting in the file actually beening seen by the phone as "PB31IMG" :eek: [I]check your file with a file manager on your phone[/I] and see how its seeing it.
b)sd card not formatted FAT32. if it is plain FAT or anything else,PB31IMG is invisible. on rare occasion,i have seen claims that a bad sd card,or card that needs reformatted(even tho it may be FAT32) will have the same affect.
*this has been addressed [U]several[/U] times in the thread,skim thru it for more information.
4)[B][I]downgrade with adb[/I][/B]. make sure your phone is charged to 100% before starting.
-on windows 7,click the start bubble and type "command" in the search box. this should open a small black command window. from this point forward,all code will be in [B]bold[/B] so you know what lines to copy and paste(or type,if you really want to type them all in). additional comments will be blue,and should not be copy/pasted. please note that each line is one command. copy/paste it into the prompt in your command window,and push enter. one line at a time.
at the end of the post,is a copy of my session,to show what the outputs of the entered lines should look like. hopefully,its a little less scary when you know that youre getting the right responses to the things you enter.
-make sure phone is plugged in and usb debugging checked on,in charge only mode
-at the promt in your command window:
[B]cd c:mini-adb_inc [/B] [COLOR="Blue"]this should change your command promt to "mini-adb_inc",indicating youre using that directory.[/COLOR]
[B]adb devices[/B] [COLOR="blue"]this should output your phones serial number,indicating its recognized[/COLOR]
[B]md5sums mtd0.img [/B] [COLOR="blue"]it should output a few things.at the end you should see this number 34307be744275f1db1dd16af04c37839
[/COLOR]
[B]md5sums flash_image[/B] [COLOR="blue"]again,it will output some things,then you should see this number: 0098a7dd6600b55fac34fc6645be5d7a[/COLOR]
[COLOR="Red"]*both those numbers must match exactly. if they do then you can procede.
[/COLOR]
[B]adb push flash_image /data/local/[/B]
[B]adb push mtd0.img /sdcard/[/B]
[B]adb shell[/B] [COLOR="Blue"]your prompt should change to a #. if it changes to a $,then type[/COLOR] [B]su[/B] [COLOR="blue"]note your phone may pop up a message asking you to allow permissions the first time you do this. if it does check "always" and touch "allow" on the superuser request on the phone screen.[/COLOR]
[B]cd /data/local[/B]
[B]chmod 0755 /data/local/flash_image[/B]
[B]cd /data/local[/B]
[B]./flash_image misc /sdcard/mtd0.img[/B]
[COLOR="blue"]you can now downgrade back to 2.2,so you can run "unrevoked forever" to regain s-off[/COLOR]
[B]exit[/B] [COLOR="Blue"]to get out of your adb shell,and back to the "mini-adb_inc" prompt[/COLOR]
[B]adb reboot bootloader[/B] [COLOR="blue"]this will boot your phone to "fastboot" select "bootloader" with the power button.[/COLOR]
hopefully what you will see now,is a blue status bar as your phone finds the PB31IMG,unpacks it,checks it,then asks if youd like to update. select yes to update with the volume up rocker. if youve never installed a full ruu in hboot,it will take a few minutes,so dont panic. place the phone gently down somewhere where it wont fall and spit out the battery. let it do its thing. push power to reboot when prompted.
let the phone fully boot,then place in disk drive mode and immediately delete PB31IMG from your sd card,as it will interefere with running unrevoked forever.
*[I][U]special note:[/U][/I] if your phone does not fully boot after running PB31IMG,dont panic. its happened to quite a few users,for some reason. simply pull your battery,boot to hboot via power/volume down and run PB31IMG again.
download unrevoked forever from here: [url=http://www.unrevoked.com/recovery/]unrevoked3 recovery reflash tool, v3.32[/url]
run it as you did the previous version. before plugging in your phone,make sure "disable phone security is checked" in the file menu. this time,it will root you,and turn the secure flag off on your radio. this is good,as it will allow you to always flash things that werent signed and approved by htc. you can flash new radios and recoveries,and flash any ruu you wish. the secure flag is in the radio,so running ruus or even accepting OTAs will not over-ride it. you will always stay s-off.
[I][U]*unrevoked 3.32 note:[/U][/I] if you check the "disable phone security" box as described above,and unrevoked still fails to turn s-off,you are not lost.[U]simply flash the s-off tool in recovery[/U]. you can find it here: [url=http://unrevoked.com/rootwiki/doku.php/public/forever]public:forever [RootWiki][/url]
if you wish to return to where you were,sign into google,download rom manger,flash the latest clockwork recovery. boot to recovery,then restore the back you made before we started.
optionally,you can now install the custom rom of your choice,along with a new recovery and radio if you desire. :)

*last and not least,this is a direct copy/paste of the AF thread,so any references to pages numbers are references to THAT thread on AF
the zergRoot method
this is for folks who for whatever reason,unrevoked 3.22 does not work to get them root access.
this could also be used if youve got a replacement device thats not setup,and you could care less about installing a recovery. this still requires unrevokeds drivers to be set up,so you can root with unrevoked 3.32 after downgrading,but otherwise,it prolly is a lil quicker since you dont need to download and run unrevoked 3.22.
alternately,use this if you just like ADB if your proficient in adb,feel free to remove the images from mini-adb_inc,and place them and the zergRush tool into whatever folder you typically push files from.
like above,this is intended for someone whose never installed ADB or entered command lines before.
1)download these files,and save them somewhere you can easily find them:
unrevokeds modified usb drivers public:windows_hboot_driver_install [RootWiki]
mini-adb_inc(contains misc image,flash image,and some basic adb tools)Multiupload.com - upload your files to multiple file hosting sites!

**make sure to check the md5 sums match those listed!**
if you dont have an md5 sum verifier on your PC,there are many out there for free. heres an example: Home of the MD5summer
3)prepare to downgrade
-extract the mini-adb_inc .zip. place the extracted folder on the root of your c\ drive. it comtains mtd0,flash_image,and some adb tools.
-extract zergRush.zip. take the image inside,and either copy/paste or drag it into your mini-adb_inc folder
-place the PB31IMG of 2.2 on the root of your sd card. rename PB31IMG. now is a good time to verify that your SD card is formatted "FAT32" by right clicking on the drive that is your phones sd card,then click "properties". if you find your card is formated anything else,youll have to re-format it. start by backing up all files to your PC as reformatting WILL wipe it clean. using your PC,do a full format to FAT32. you can then transfer the files back. *this is important-as your phone will not find the downgrade PB31IMG unless your card is formatted to FAT 32,and the file is correctly named.

-at the promt in your command window:
cd c:\mini-adb_inc this should change your command promt to "mini-adb_inc",indicating youre using that directory.
adb devices this should output your phones serial number,indicating its recognized
md5sums mtd0.img it should output a few things.at the end you should see this number 34307be744275f1db1dd16af04c37839
md5sums flash_image again,it will output some things,then you should see this number: 0098a7dd6600b55fac34fc6645be5d7a
md5sums zergRush again,output stuff, then this number: 3cf8a3fbceb667121d91f4ef1a66684c
*all those numbers must match exactly. if they do then you can procede.
adb push zergRush /data/local/
adb shell this will change your promt to a $
chmod 755 /data/local/zergRush
/data/local/zergRush
this will cause zergRush to start,and it shoudl say "found a gingerbread!" followed by a bunch of other funny stuff.
last thing it says will be: Killing ADB and restarting as root... enjoy!
you should then be returned to your "mini-adb_inc>" prompt
adb push flash_image /data/local/
adb push mtd0.img /sdcard/
adb shell your prompt should change to a #
cd /data/local
chmod 0755 /data/local/flash_image
cd /data/local
./flash_image misc /sdcard/mtd0.img
you can now downgrade back to 2.2,so you can run "unrevoked forever" to regain s-off
exit to get out of your adb shell,and back to the "mini-adb_inc" prompt
adb reboot bootloader this will boot your phone to "fastboot" select "bootloader" with the power button.
hopefully what you will see now,is a blue status bar as your phone finds the PB31IMG,unpacks it,checks it,then asks if youd like to update. select yes to update with the volume up rocker. if youve never installed a full ruu in hboot,it will take a few minutes,so dont panic. place the phone gently down somewhere where it wont fall and spit out the battery. let it do its thing. push power to reboot when prompted.

edit:apparently the zergRush tool has changed. ive included the new md5s,so hopefully there wont be any more confusion like the old md5s caused earlier. be aware of this,however, in case they do change again. you are right to be cautious if it doesnt match,so ill do my best to keep up with it.
This does work, but god I wish it was all ADB it was all so easy before unrevoked it didn't work the first time it gave me SU and root but no s-off then unrevoked would not run again due to new firmware. I did full downgrade to 2.2 and followed all directions ADB is so simple but unrevoked took 2 hours of just missing around to get s-off which included flashing 2.2 in hboot again starting over, running what I could run again in ADB without the gingerbreak since I was now on froyo, it was mostly just repushing the files and binary. But after all that unrevoked ran and gained root and s-off. Worst root I have ever done but people its all about making smart decisions before you do it if you make a mistake and get stuck, get help or trouble shoot but use you head before you battery pull and make sure you read before you hit anything.
If I helped you in any way please use the thank you button
sorry you had such issue with unrevoked. usually thats the easy part most folks are confused by adb and running commnads and wish it was all automated!
just a couple things that may help folks in the future:
-if you dont want to fool with unrevoked 3.22 in 3.2.4 use the "zergRoot"method in post 2. its all adb up to the downgrade. once you get to this point,you could easily roll yourself all the way back to the shipping firmware(assuming amoled screen) if you wanted,and then use an adb method(if one exists,im not that flamiliar with the inc). you dont have to go back to 2.2. i just picked that cause most folks are familiar with it,and with using unrevoked 3.32 to root/s-off it
-there have been a few complaints of unrevoked not giving s-off on 2.2. before you start,make sure "disable phone security" is checked in the file menu. if s-off still fails,but gives you root and a recovery,its worked for everyone thus far to just run the "forever" .zip in recovery,no real need to reflash the 2.2 ruu and run unrevoked multiple times.
-last and not least unrevoked is not ever going to give s-off in the 2.3.4(unless they release a new version for 2.3.4),as is uses an unsupported baseband,thats why the 2.2 downgrade is needed. folks that have no intention of backing up or returning to 2.3.4 and are fairly savy like the poster above,id strongy encourage to just use directions in post 2,its a lil quicker to not have to mess with unrevoked 3.22. its mainly included for the folks that want to make a nandroid or run tibu prior to the downgrade(plus zergRoot hadnt come out yet,when i originally put this together )
once your back on 2.2 you could even just use z4root to get get root access,install rom manager and clockwork,then flash the forever patch. once you can downgrade,there are alot of ways to skin the cat
Worked after a few tries!
Thanks Scotty for this writeup. I thought for a minute that things wouldn't work, but a third try proved fruitful.
Here's a few tips that I can add to things.
Things failed for me at the restore 2.2 part - HBOOT would not recognize the zip file as correct.
I am on a Win XP machine... Format the sd card to fat 32 using something other than Windows - I used a little program called "fat32format.exe". Windows seems to have a problem formatting sd cards correctly, so that could have been it.
Once I made sure the sd card was formatted, I put the 2.2 zip (PB31IMG) back on the sd card and started over using the zergRush method.
If you have tried this before, you will have to remove two directories from the /data/local/tmp directory. These are sh and boomsh. Thanks to ieftm in this forum for this tidbit of info.
If your zergRush is giving you problems stating:
[-] Cannot copy boomsh.: Permission denied
Then use this method to fix as I stated in paragraph above: remove sh and boomsh
Once these directories were removed and the zergRush was completed, the downgrade commenced just as described.
Side note - Unrevoked 3.32 installed Unrevoked forever automatically onto my DInc, so there was no reason to do the additional forever installation. You may have the same results.
For anyone else that can't seem to get things working, the search is your friend. It took me a while of hacking away at things, but eventually they all turned up roses...
Good Luck!
problems install roms
I have a problen,I can't install a Rom error e: can't open/sdcard/primexl3d.zip, why?
saosinalm:
First off, that's the wrong name for the downgrade zip according to the instructions that scotty posted above. Make sure the file is titled correctly and follow his instructions from beginning to end. I believe when mine succeeded my file title was "PB31IMG.zip" but in his instructions he leaves off the ".zip" at the end.
If there is an error in the process, you will have to start over from about step 3. You can't just start back from where you left off if you reboot the phone. Make sure you check your MD5's once you download, then you won't have to go back over that step.
I found the zergRush method easier, but I am more comfortable with adb...
I would suggest re-reading the instructions and following closely - he walks you through things really well.
I have one question....
Why root a phone? I had my phone rooted and honestly it was a complete waste of time. NONE of the Roms I downloaded ever worked properly, the apps never worked, and it was nothing but trouble for me. My phone always "force close" my apps too. No offense to the developers I just didn't see a benefit.
Am I wrong?
epescina:
That's really best answered differently depending on the type of person you are. If you like to play around and experiment with things or like learning how things work, maybe this works for you. Some people do it to get a custom look that no one else has, some do it to try and get better performance out of their phone that may have been bloated with apps out of the factory, and others are learning about developing apps and programming with it. Every person is different. Maybe it's just not for you, but others on this board can't live without it. To each his (her) own...

what are you trying to do exactly? no part of this guide requires you to flash a rom. so if youre tryingto root,be more specific what youre having trouble with, and if this is just a general question about flashing roms,you might do some research and/or post a new thread where more people will see it

i personally have the opposite experience. while there are a couple minor issues with the rom that i run,i feel my phone is faster and more pleasureable after root. i love htc phones,but hate htc sense,so i root mainly root so i can run AOSP based firmware.

I too hate the HTC Sense and wish I could change the overall layout of my phone. When I did load a new ROM that changed the layout it always seemed to be screwed up for one reason or another.
For example the lastest rom (Cyanogen) I absolutely loved but it didn't have market and I never could find out how to load it!

Couple of quick questions (which might appear silly):
"place the PB31IMG of 2.2 on the root of your sd card. rename PB31IMG"
#1) What do we rename "PB31IMG.zip" to? The directions simply state to rename it.
#2) Move it to the root of the external sdcard or internal sdcard?
tia, and I hope these questions weren't too ridiculous.

It should be named PB31IMG.zip
It all depends how you rename it, if you use your pc it may not show the.zip extension if you have "show extensions" turned off. So on your pc it may just say PB31IMG even though it is really a zip. Sometimes when extensions are off people end up naming it PB31IMG.zip.zip wich will not work. It is best to have your pc show extensions you can do that by going to controll pannel / folder options / view tab uncheck hide extensions for known file types.

wow lol ok, that just seems common sense, but I guess you never know who your audience is
Which sdcard should the file be on?

It should be on the removable sd not the internal storage if thats what you were asking.

thanks again, just making certain. going for my third try now!
---------- Post added at 01:20 PM ---------- Previous post was at 01:14 PM ----------
I'm getting an unmatched number on zergRush
"md5sums zergRush again,output stuff, then this number: 795275fb9c41ebd5b9fe7ab19108c52b"
I get "4bf71b766a9603fa7db98e71e3f3b470"
??
It states:
"*all those numbers must match exactly. if they do then you can procede."
What do you do if they don't match?
Sorry for the n00b questions, been dealing with nothing but HC since June.
I would try redownloading and then check it again. If its still wrong i would contact the op scotty and ask him, as he is the one who provided the original md5.

thanks, d/l it three times already what a PITA
I get a md5 of
3cf8a3fbceb667121d91f4ef1a66684c
for the zergrush file in the zip and.
12c52b97e75e73595b325c03610b3380
for the zip it self, different than both of your guys.
Edit. I believe that the zergrush file has been updated since this post to include more phones so that is probably why the md5 is different.

[Q] Downgrade issues?

I'm having issues during the downgrade process.. My temp root works fine but when I try to access PD15IMG.zip from the bootloader it skips the files.. From that screen it appears to be looking for PD15IMG.zip..
I tried swapping the files .. naming them vice versa but it does the same thing..
anyone seen this? any workarounds?
Maybe your PD15IMG.zip file got broken during download or while copying to sdcard. You can check that md5 hash of PD15IMG.zip exactly matches expected value (for 1.17.531.2 firmware it is 49d07f0ee7de1765a6a84cb12fa53110). There're different ways to do this: i.e. run "md5sum /sdcard/PD15IMG.zip" from adb shell or you can find some regular apps from Market that are able to do that - ES File Explorer, for example.
Forgot to mention:
Have you already decreased version number to 1.00.000.0 via misc_version utility? If you didn't - that's probably why your bootloader doesn't want to "update" the firmware - you should make it think your current version is below 1.17.531.2 before trying to downgrade.
Ok; I was following this GUIDE - http://forum.xda-developers.com/showthread.php?t=1178912
Which notes.. myTouch 4G: PD15IMG.zip
Should that be PG59IMG.zip for some devices? Or will the Bootloader switch to looking for PD15IMG.zip after the misc version step? I guess I'm just unclear on the stock rom step.. all other steps prior work and I'm temp rooted seeing the # indicator.
Checks out Like this -
dd if=/dev/block/mmcblk0p17 bs=1 skip=160 count=10
1.00.000.010+0 records in
10+0 records out
10 bytes transferred in 0.001 secs (10000 bytes/sec)
thank you so much! I wish HTC would just let us disable Sense

No, name of the image file differs from one device family to another. For MyTouch 4G it is definitely and exactly PD15IMG.zip (also, note: it's case-sensitive).
Btw I myself careful step by step followed this guide to downgrade, and everything went smooth.
I've tried the same approach.. I seem to be missing something here..
Use Volume up/down keys on the HTC Glacier for navigation and Power key for confirmation. Select Bootloader to flash the 1.17.531.2 firmware.
I click power.. It scrolls thru the files.. FINDS the PD15IMG.zip file..
I see a small blue progress indicator in the right upper corner.. that completes and it returns the bootloader screen..
Should I reboot now? Lose my temp root at that point.. (assuming it didn't update the ROM w/ my PD15IMG.zip file)
So I can't proceed to the busybox ROOT
_any help_ is greatly appreciated -
thanks guys(& gals )
You lose your temp root at the point when you reboot to bootloader to achieve the downgrade, way before you reflashed your ROM.
You don't need that temp root the moment you've downgraded. The whole purpose of downgrading is to make an easy temp-root and then permanent root available.
Please, just follow the rooting guide.
I should have been more clear.. I am following the guide exactly;
The guide says...
adb reboot boatloader
after pushing the ROM replacement to the SD card..
My issue is that the ROM doesn't appear to 'do anything' the bootloader finds it.. quick blue status bar and then nothing..
misc version reports the right version prior at a # prompt..
Just unsure of what I'm missing..
Followed the steps numerous times to the same result
There is no question on the screen after the blue bar is filled? In the same small font, on the left side?
In that case, the ROM doesn't pass verification. You'll need to turn off the phone, take out the SD card, put it into the computer (use card reader if you don't have one built in), format it, copy the ROM on it, and boot to bootloader again with the card in the phone.
If it still won't be recognized - then re-download the ROM and verify MD5SUM before using.
