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)

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?
Most of this information has been repeated so many times. But I wanted to make a short list of all the silly mistakes and simple oversights I’ve made over time.
(I make mistakes constantly - there are probably some mistakes in this very post - and I usually search around and try to find my way out of them. I will edit this post whenever I run into a problem. If anyone has any input, I will gladly add it to this post.)
YOU CAN NOT COME BACK FROM UNLOCKING YOUR BOOTLOADER:
If you ever think you’ll need to or want to “relock” your bootloader, you can’t.
Alternative root method:
VISIONary
(when you launch the application, you can leave everything unchecked)
Alternative recovery option:
ROM Manager (in the market)
ALWAYS DO A NANDROID/CLOCKWORKMOD BACKUP!
It will restore everything the way you had it if you F something up.
Want to go back to original shipping, but followed this guide, downloaded the linked file and can’t find the image files?
They’re not in that file. I don’t know why. Go here and download FRG33, decompress it and use the contents to follow the tutorial
Are you getting a “verification failed” error when you try to apply an update.zip in recovery?
Mount your SD card to your computer, download whatever file you were trying to apply directly to it (don’t download it and then drag it), and rename it to “update.zip”.
If you’re using Windows, make sure “hide extensions for known file types” is unchecked in your folder options within the Control Panel. You’ll keep having problems if it’s named “update.zip.zip” and you didn’t realize it
If you're still having problems, try this download of the stock FRG83 update.
<Added 11/18> I had another facepalm moment. If you downgraded back to FRG33 and you get an "assert failed" error, flash the recovery.img from that FRG33 package you extracted. (found this solution here)
Did you flash a ROM or go back to stock, start up your phone and noticed that you’re stuck on Edge?
Go to Menu>Settings>Wireless and Networks>Mobile Networks>Network Operators>(choose your carrier), wait.
Trying to copy something from your SD Card to /system/app (for instance)?
If you use the “cat” command, DON’T FORGET THE “>” SYMBOL. Nothing awful happens as far as I know, but it’s unnerving to watch the terminal puke all over itself.
Code:
cat /sdcard/thing.apk > /system/app/thing.apk
If you’re new to Linux and/or Android and are removing apps:
BE CAREFUL with the “rm” command. Once it’s gone, it’s gone.
You can always rename (technically, "move") the files instead:
Code:
mv /system/app/thing.apk /system/app/thing.apk.bak
Switch the commands to get it back
Code:
mv /system/app/thing.apk.bak /system/app/thing.apk
And don't forget to mount /system as read and write. To do that:
Windows: (must have drivers installed, Nexus One drivers are in the SDK)
Code:
adb shell
su
Linux: (no drivers necessary)
Code:
./adb shell
su
Code:
mount -o remount,rw -t yaffs2 /dev/mtdblock3/system /system
Don't forget to mount /system as read-only when you're finished. To do that, use the same code but replace "rw" with "ro" (without quotations of course)
Having trouble connecting with adb?
In Linux, you need to be in the SDK directoy (mine is in ~/AndroidSDK/tools). In Windows, you need to have ;C:\AndroidSDK\tools in the system path, within Environmental Variables (right-click on Computer>Properties>Advanced>Environmental Variables)
Unplug the device
In Linux, cd to ~/AndroidSDK/tools (or whatever you called it) enter:
Code:
sudo ./adb kill-server
sudo ./adb start-server
Plug in the device
Code:
sudo ./adb devices
In Windows:
Code:
adb kill-server
adb start-server
Plug in the device
Code:
adb devices
Device not found?
Did you enable USB Debugging in Menu>Settings>Applications>Development?
Trying to install an .apk but it just won’t work?
Try the “adb install” method, or push the apk to /system/app. If the app force closes or doesn’t work, just remove it
Code:
rm /system/app/thing.apk
Using Ubuntu (or another Linux distro), trying to mount your SD through Amon-Ra's recovery, but it won't mount?
Disable USB-MS toggle, unplug the phone, reboot your computer, try again.

I'm glad you appreciate it. I'm not technically one of the guys on here. I've been on XDA in different device forums for a little while but have always been absorbing the information and never giving anything back. This is my first try. I can only dream of being a developer when I grow up, and solving more serious problems.

Just wondering ahorriblemess, I looked over the guide and it says:
"This will do the followings to your Nexus One:
1. Reset your system files to the original system files.
2. Reset your kernel/boot image to the original shipping boot image.
3. Reset your recovery to original recovery (if you wish)."
Since I'm a real idiot... does this guide get your baseband / radio back to original (january) shipping image as well?
I didn't see it in those 3 things and have the 5.12.00.08 version so I wanted to make sure following that guide would reset the radio baseband back to the original (january) version as well before I did it.
Now all I need to do is figure out how fastboot works and I'm gold!

I don't know. I'm in no way an expert at any of this. My intent with this thread was to compile all of the sort of simple things that I've overlooked in the past. Usually I've found solutions to those problems scattered all over the place, so I just thought it would be helpful to put them all in one place in case anyone ever has the same problems I've had.
I have a pretty good feeling about the answer, but I don't want to share it in case you decide to act on it and it's wrong.
Thanks a ton!
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.
http://forum.xda-developers.com/showthread.php?t=1193737
This might be more helpful:
http://forum.xda-developers.com/showthread.php?t=1100189
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

So I was randomly flying around on Google today, and I noticed that someone had claimed to root the Kobo Arc, and gave written instructions here -- http : // www . mobileread . com / forums / showthread.php?p=2584491 (Remove the spaces, XDA won't let me post an actual link, since I don't have 10 posts yet). After running through this myself, I went on the Google Play store and used root checker. Much to my surprise, it worked, and my device now has root access. I even tested with Root Explorer, and mounted the system partition as R/W, and I can move things in and out of it. I'm currently working on trying to get a custom ROM working, but I'm worried that I will cause a brick, since Cyanogen doesn't support the Arc. (yet...)

In terms of a ROM do we not need a compatible boot loader that will allow unsigned ROMs?

i have absolutely no idea what im doing but I think I have dumped 12 partitions using

is there anyone around that fancies a challenge? im in a position where bricking this thing isn't really much of a problem so if someones up for a challenge and wants to help im willing to lend myself and the device to this

Haha. As soon as I found a thread called "root the Kobo Arc" on Google, I posted it here right away. Sorry if I deprived you of the satisfaction! *troll*
Joking aside, I'm not too sure about the bootloader. I think it's pretty locked down (since I put a nexus 7's cyanogenmod onto the data partition and rebooted. It tried to updated, but said validation failed, or something of that sort). I can't install any custom recoveries either, since I have no idea how to do it in the first place, and there's none made for the Arc.
Also, I analyzed the Arc with the "Droid Examiner" App from the play store (That is a really great app, just so you know), and found that it uses a board called "zeus". The funny thing, though, is that one of Sony's Xperia phones, also has a board called "Zeus", and there's Cyanogenmod for that (albiet not the latest version). However, these two devices have nothing in common. The closest thing to an Arc that has Cyanogenmod is the Nook HD/HD+, which uses the exact same chip (OMAP TI 4470).
If someone is smart enough (not me) to analyze the Cyanogenmod files for the Nook, and see how they work, that may lead into flashing the Arc.
Anyway, I'm resetting the Arc, since I'm having weird cases where the Arc would freeze after booting it from sleep mode, and I'd have to turn it off and on again. I think that was something else I did, since it happened before the root, but neh, I might as well try this all from factory default settings.
Sorry for the block of text, guys!
P.S. Using the stock Jelly Bean boot animation on the Arc looks amazing!:laugh:
Haha, its cool, like yourself I just happened to Google kobo arc root and for once my googe fu was up to the task and the root appeared
I've been looking at starting my own recovery mod branch but its no simple task by the looks of it, if their are similar devices we can use all their data and tweak it to ours which would help a lot!
Oh I think we have fast boot, I held vol down and pushed power on, it just sat at the kobo arc screen, I used the nexus 7 driver from the universal adb/fastboot driver I found on here and it connected up http://forum.xda-developers.com/showthread.php?t=2263822
I stumbled on some to good to be true program on Xda dev that apparently can root anything and unlock any bootloader once your in fastboot mode. I have tried that part and it said it was successful but i have no idea how to test this out yet, the program does a bunch of other stuff too, the adb stuff worked as did apk sending, and the rooting options knew i was rooted, it also has flashing functions, I'll be damed if I can find it now I'm at home though , I'll have another look.
I don't mind doing leg work but if someone can read the map it would be very helpful!

Um... Okay. I've installed the drivers (I think I installed them correctly), and I booted my device using "volume down + power". I have it connected to my System, but whenever I try to use one of the options in the Android Root Toolkit, it tells me it's waiting for the device. I don't know what I did wrong, but something's clearly not working.
As far as the recovery goes, I think that looking at the Nook Tablet from TWRP would work quite nicely. It runs on a similar processor ( I believe it's a OMAP TI 4430 ), and it seems to be quite similar in specs to the Arc. If only I was a bit better at programming...

im usig the generic android adb driver and the bootloader driver for fast boot
im dumped all partitions and mapped them all out, see below for file system details
But again I'm blindly stabbing in the dark and most tutorials are a bit lacking in depth or not relevant to the kobo :/

Okay, so I can't even push apps to the Arc using ADB. I think you have to boot into recovery (power + volume up). I don't know how to use the terminal at all (I'm lost, I know D: ), so I don't have that installed on the Arc. I remember being able to do ADB even with my Sony Reader (First gen, PRST1), so I'm not sure why the Arc isn't quite working. I have both drivers installed, BTW.
As for the recovery, I can't even find a method to flash it. I'm still trying everything I can, though. :\

Watching with interest. The root works. No frills CPU installed and working. There may be hope for this thing yet:good:
Moved to new thread and more appropriate forum - keep up the good work guys
im not sure that's going to work you know, ive had some permission errors with adb which suggests the root isn't full, terminal on the device works fine, but adb just has some problems, adb shell and the su seems to fix them.

i think Clockwork Recovery should be our focus at this point or if you have dumped your partitions(?) attempt to construct a rom for later use
or this should work too
Install any Custom Recovery with flash_image:
Just like the previous method, this method also requires following advanced steps and is not recommended if the first method is working for you. flash_image is a tool for Android devices that lets you rewrite your phone’s system partitions with partition image files and installing it to your device requires ADB. If you don’t already have ADB installed, check out our guide on installing ADB. Once you have ADB installed, flash the custom recovery image as follows:
WARNING: It is very important that the recovery image that you use in this method is compatible with your device. Else it will not work and flashing it could possibly brick your device.
Download flash_image and extract it from the zip file to a location on your computer. We extracted it to the main C drive (not in any folder) and will use that in the next steps.
Copy the recovery image for your phone to a convenient location on your computer, preferably with a short path. We will be placing it on the C Drive directly (not in any folder) and using that in the next steps.
Note: The recovery image should have .img extension. If it is in a zip file, extract the .img file from it.
Enable USB debugging mode on your device from Menu > Settings > Applications > Development.
Connect your device to your computer via USB.
Open a Command Prompt window on your computer and enter the following commands: adb push c:\flash_image /sdcard/adb push c:\recovery.img /sdcard/adb shellsumount -o remount, rw /systemcp /sdcard/flash_image /system/bincd /system/binchmod 777 flash_imageflash_image recovery /sdcard/recovery.imgThis will first transfer flash_image and recovery.img to your phone. Then it will copy flash_image to the /system/bin folder of your Android device and make it executable. Finally, it will flash the custom recovery image to your device using flash_image.
Note that we used c:\flash_image and c:\recovery.img in the first two lines as we had these files extracted at the root of our C drive. If you extracted the files elsewhere, use the appropriate paths and if your recovery image has a different name, use the appropriate name.
Reboot your device once the process is finished and you’re done. You may exit adb and the Command Prompt window on your computer by entering ‘exit’ thrice.

I've already tried that recovery method (I spent about two hours just googling), and it doesn't work with the Arc. The ADB won't let me push the image over.
As for Cyanogenmod, I tried something yesterday. A person on the Mobileread forums (apparently a Kobo employee) put out an update.zip file for the Kobo Arc. The file was quite old, and it's really just the 4.1.1 update that (I hope) we're all running. He said that as long as you put it on the root of the data partition, the Arc will flash it immediately. When I tried taking a Nexus 7's Cyanogenmod file and sticking it in the same place, the Arc started flashing it, but then just said there was an error with the update. So I personally think that you do require a properly signed ROM.
However, if you open up Kobo's update.zip using Winrar, a sidebar pops up that says "signed by SignApk". I don't know too much about this, but couldn't we use this "signapk" to sign our own ROMS and flash them?
Just a thought.

I think there is a problem with the setup, I just flashed a CW recovery image and it worked, or didn't rather! but the concept did, transferred, flashed using adb, I had to replace it though as it was totally borked and kept restarting, apparently the touch based recovery methods can be like that, ill have some good time tomorrow night (UK time) if your about, and ill keep at it tonight if I get a chance!
copy recovery to adb location
adb push recovery.img /sdcard/
adb shell
su
cat /sdcard/recovery.img > /dev/block/platform/omap/omap_hsmmc.1/by-name/recovery
exit adb shell and type
adb reboot recovery
fixed it by holding power button and vol down to boot to fastboot recovery
then ran
fastboot flash recovery inputrecovery.img
inputrecovery being my original recovery file taken from partition 8!
ive updated the partition map on the post above with my progress, but it looks like we can flash to them my name so its probably less relevant now
oh ive ditched the drivers I was using and reinstalled the drivers from the official SDK, generic android adb for within android and android bootloader for fastboot
EDIT
Yaaas!! recovery replaced
ok, deleting or renaming /etc/install-recover.sh appears to have stopped custom recovery being changed back to stock after reboot, I used the recovery builder to make a build from partition 8, which it did without error, flashed using the above commands.
Still don't know what im doing though, but progress is progress
ill post a link to the custom recovery ive made soon, we need to make up some fstab file listing all the mounts etc, i tried one but it must be borked as recovery couldnt see anything
ok i have a working recovery http://jenkins.cyanogenmod.com/job/recovery/35325/artifact/
its not quite done, i need to mount the sdcard, its physical location is mounted, ie /data, but its virtual mount isn't /storage/sdcard
I have asked for some help so hopefully someone can help be on this, I think it needs to be symlinked
im going to need some help soon, so if your reading this with a kobo arc, I need you! im needing a hand folks! if your stuck getting this far let me know and we can PM to get it working
oh and recovery is also now persistant by deleting or renaming /etc/install-recover.sh"
Sorted folks!
I have made a stable and thus far, a working custom recovery.
its mounting everything and backing up / restoring works as it should, unless anyone can find any issues I consider this step in building a complete ROM completed,
you must have root, download arctic.apk and install on your tablet, you will need to enable unknown sources In dev options first
you must have android and java sdk also installed, you will need to add the google usb drivers in the android sdk, you will find them in the "extras"
Enable usb debug on the arc and install the generic google adb usb drivers
Delete or rename /etc/install-recover.sh this will make the custom recovery persistent
Copy the recovery.img to the SDCard, either by using drag and drop in windows ( to root of "internal storage") or by adb push, if you use adb push then remember to copy recovery.img to the same folder as adb
adb push recovery.img /sdcard/
The next job is to open up a command window and navigate to adb folder, type the following exactly, even better copy and paste them!
adb shell
su
cat /sdcard/recovery.img > /dev/block/platform/omap/omap_hsmmc.1/by-name/recovery
exit adb shell (ctrl+C) and type
adb reboot recovery
and bobs your uncle, one happy new recovery
Thanks for your hard work. Everything works quite well.

that's the easy bit, I have a feeling I need to make a couple of changes to the recovery.img but noting major, just a couple of other mounts I may have missed
I probably would like some help with the next bit however.
im just trying to build a development platform, I have a loathing for Linux as a desktop so will need to re educate myself without throwing my laptop out of the window, after that "challenge" the ROM should be easy
Well, I've just done it, and it works. Everything seems to be in order for the time being. I'm going to muck around with the new capabilities, and see what I can do.
Hello good peoples of Xda ,
I just purchased a Note 3 verizon I believe 900v on swappa It will arive in the next few day's and I want to get all my ducks in a row by that I mean aquire all the root and unlocking tools nessary for a best practices root and if nessary unlocking of my boot loader.
Goals for root are mostly to debloat the phone and hotspot mod's for no hassle teathering.
I may dip my toes into custom rom for this phone but mostly I am just looking for a clean lean experiance for my note 3. I have been pouring over the many many pages of the various rooting guids and I am just not sure witch method to use is the safest / most reliable .
thank you for your time and helpful suggestions.
This is what I have found so far.
ArabicToolApp : Root for lolipop
Odin3 v3.12.3 : flash tool is this latest ? best to use ?
Samsung usb drivers v1.5.45.0 : are these the proper drivers to install ?
You should start by figuring out which firmware release it has on it.
If it has PL1 (the newest security release, circa 2017/01/15), there will be no rooting for you... unless you manage to create a new exploit.
OB6 and OF1 - (one of) the yemen tool(s)**
NK1 - no root available ( and can't be rolled backwards w/ Odin, only NK1 or higher )
NJ6 - no root available? ( Try towelroot, or you can downgrade to NC4 using Odin )
MI9/MJ7/MJE/NC2(leak)/NC4 - Towelroot v3
For which bootloader unlock binary to use, see here.
Can't help you out with USB drivers, I don't remember what I used. afaik, they will either work 100% or not work at all, so you just need to get something working.
I've never used anything but Odin 3.0.9. Can't tell you if the version you mention is "better".
good luck
** i've never rooted OB6 or OF1, so can't give you any advice about which to use. Feel free to read the related threads. In my (casual) reading of those threads, it is nearly impossible to intuit out why some people have problems and others do not. Mostly because the reporting is not sufficiently detailed.

Your right, after thinking about my post I realized there were 2 many variables that I need to know before I ask for help. So once I recieve the phone and if it's fully functional I will find out what firmware it has and what the cid it has and will post a follow up if I need help.
P.S thank you for the concise jist of what is and is not possible with the various firmware's.
Recieved my phone.
I got my note 3 and boy is it just a wonderful device. SM-900v running OF1 firmware, and My Cid is 15 so is all good.
procedurs completed.
I got root from useing the yemem tool.
and have tryed some debloating removed the NFL apk as a test with Tit.backup.
dissabled ota updates, I made a copy of the update.zip (that was downloaded with out me asking it too. I assume that this update.zip is the new PL4 firmware )and deleted it. renamed the fota.apk's with a .bak
not really sure if I should unlock the the bootloader I would love to have twerp.
Could anyone point me at a good debloating script ?
LOVE LOVE LOVE my note 3.
I also have a zero lemon battery/case combo on the way.
PL1 not PL4
See here. Might be dated - stuff tends to move around from release to release.
You should probably also freeze SDM.* and SysScope.* (in addition to LocalFOTA)**
There is a small permanent downside to unlocking - the blowing of the Knox Warranty Flag means that you will never be able to use Knox Secure containers, even if you did a full stock flash with Odin. Not sure how important this is to folks using the phone as a personal device (as opposed to a corporate device).
Operating with a rooted-stock device with a locked bootloader usually progresses through a customary arc - especially with new rooters, but also with experienced folks - where the user one day does some incremental mod that boot-loops the Android UI. At that point there is no means to reverse the small change. (You can't get in via "adb" as it's daemon isn't started yet, and even if it were, the fact that it is in secure mode means that you would have to have a stable UI in order to confirm the connection.) As there is no rooted secondary boot available (i.e., a custom recovery), there is no way to perform repairs, and a trip back to Odin is in store for the owner. Worse yet, a backup has never been made... so all customizations are all lost and must be re-created completely from scratch.
** this is a good idea if you unlock and install a custom recovery: (although TWRP may detect it and emasculate it automatically)
Code:
su
chmod 0000 /system/bin/install-recovery.sh

Right PL1 ok.
Well I decided in for a penney in for a pound and have sucessfully unlocked my boot loader, had no issues.
my question now is how do I install twerp I have downloaded
twerp-3.0.2-0-hltevzw-4.4
and twerp 3.0.2-1-hlte.img.tar
I think I need to install the tar file.
but I don't know how. I have odin but not sure if that is the right program to use. I think I read where somone installed twerp with flashify or somthing like that.
What should I do ?

man up and use a root prompt command line. It's a single command.
Code:
dd of=/dev/block/mmcblk0p15 if=/sdcard/twrp-3.0.2-0-hltevzw-4.4.img bs=2048
( assuming that you put the twrp .img file in the /sdcard folder. If it was in the download folder, then if=/sdcard/Download/twrp-3.0.2-0-hltevzw-4.4.img )
Note there are absolutely, positively no spaces anywhere in "mmcblk0p15". Critically important.
The above command writes a raw binary data (the .img file) to the 15th partition of the mmcblk0 device - the flash memory chip. You can do this with boot images (such as custom recoveries) or a few other binary images, but typically not with ext4 or other filesystems.
Note this command could be extremely dangerous if you made a mistake. If you were to write data someplace else it could be a permanent disaster. So cut-n-paste to be safest (without a new-line), and then double- and triple- check the command for typos before you hit the enter key.
FYI, you can see what the partition mapping is by doing a folder listing
Code:
ls -ld /dev/block/platform/*1/by-name/*
The partitioning scheme varies from android device to android device; but on the SM-N900V the recovery partition is the 15th partition. (On other devices it might be something different).

are you talking about adb ?
So somthing like
adb shell
su
dd of=/dev/block/mmcblk0p15 if=/sdcard/twrp-3.0.2-0-hltevzw-4.4.img bs=2048
???

That works.
Or a terminal emulator.
All you need is to put the file on your (internal, pseudo-) /sdcard, "su", and "dd".
For extra credit, make sure to compute a file checksum (e.g. "md5sum") every time you copy the original .img file to a new location and especially prior to flashing. That safeguards against a bad copy operation, crappy flash memory, etc.
Stock ROMs might not have a "md5sum" binary in /system/bin, but since you are rooted you could install a private busybox in someplace like /data/local/bin. I prefer to use a busybox which is SELinux-cognizant, e.g. v1.23.1 here as busybox_full_selinux_1.23.1.zip Note that I don't "install" this .zip so that stuff in /system/bin or /system/xbin get overwritten, but instead just keep it in a private area all on it's own.
Steps.
0) extract the "busybox" binary from the .zip file and get a copy to your SD card. Then
Code:
su
mkdir -p /data/local/bin
chmod 755 /data/local/bin
cp /sdcard/busybox /data/local/bin/
chmod 755 /data/local/bin/busybox
cd /data/local/bin
./busybox --install -s /data/local/bin
This allows it to be used as needed in a terminal/console shell.
e.g. using ls
1) Explicitly: /data/local/bin/ls -lZ *
2) Implicitly "as a last resort":
export PATH="${PATH}"':/data/local/bin'
ls -lZ *
3) Implicitly "as preferred":
export PATH='/data/local/bin:'"${PATH}"
ls -lZ *
I am now have root, unlocked bootloader and twrp Whoot!!
Well I now have twrp installed thank you vary much for all your help and direction I sincerly appreciate your assistance.
I installed termux and after updating the packages sucessfully used dd to install twrp.
1st thing I am going to do a full system backup.
No developer love for N900V not good
