HOW TO DO IT?
Go to developer settings and turn on usb debugging. Root your device with KingoRoot. Turn on your phone in download mode ( hold vol - button and at the same time plug micro usb to phone). CSE flash d620r10g.kdz and boot it to the system. If system is not booting do a wipe. Now go to settings and turn on usb debugging. Now download Terminal Emulator, Root Checker and Rashr. Now root it again with KingoRoot. Now MOVE aboot4.img to internal storage to any folder. Now check if you have root access. If you don't have root access root phone again. Now open terminal emulator and paste this code (do not rewrite!!!) su (confirm)
mount -o rw,remount -t ext3 /dev/block/mmcblk1p21 /system (confirm)
dd if=/dev/block/platform/msm_sdcc.1/by-name/aboot of=/sdcard/aboot.img (confirm)
dd if=/sdcard/aboot4.img of=/dev/block/platform/msm_sdcc.1/by-name/aboot (confirm)
reboot (confirm)
Now you have rooted and unlocked bootloader in D620r!

You don't put aboot4.img into any folder you want. You need to put it in /sdcard/ because that is the command you are using.

hi this is what i get when i input the 2 lower commands into the shell: "abootb.img: cannot open for write: No such file or directory".
Any ideas?

Abootb is not in the folder you targeted.
Find where it is and target it, or move it.

Ok so I searched through all the folders with no joy. I just don't get it. I followed all the steps from this tutorial and tried the other as well but got the same message. Btw root is present in able to execute first command but the remaining two give me the error message. I'm in 620r

You can tri change sdcard with storage/emulated/0 and probably work. For me this method worked.:laugh:

Yeah, he is right.
dd doesn't work well with symlinks (like /sdcard).

Hi guys thanx for the reply. I have figured it out myself by it was indeed as syrrix01 suggested. Everything was in storage/emulated/0....again thanx for quick replies

Does this guide work? My brother made a joke when I left the phone at home and blocked my bootloader

It should.
Just replace /sdcard with /storage/emulated/0
Also, wasn't it you who wrote this guide?

Yes, I wrote this guide XD i get inspired by this video : https://www.youtube.com/watch?v=JH7TSyxv_0E
edit:
I am afraid to unlock the bootloader because I think I will make brick for the third time

The guide seems good.
Just replace /sdcard with /storage/emulated/0 and you will be fine.
Still, I take no responsibility.
Your device, your mess.
I will try to help you fix it though, of course.

Okay, I will try this.

Can someone get....

I'm in need of the stock kernal image and the clockwork recovery.zip file thingy.
NOT the zip verson of the kernal installer.
My situation, I was stupid and installed the voodoo thing, then for someone reason I tried to flash Froyo over Bionix with the voodoo kernal thing. It didnt work so I decided to deleted everything in clockwork. Then I was like omg I cant use clock work or boot my device (stuck on vibrant screen but I can get to odin and the stock recovery).
Later I read that voodoo stopped odin on the cm forum so I couldnt use it. Thats what some dude named viralblack said and theyre a mod so I'm guessing its true.
So my last 4 ideas are:
1)Try and flash a new Kernal Image in adb and hope it gets odin to work
2)Push the cw recovery to the phone
3)Run to the library and hope my computer is the problem
4)Pretend vb is wrong and keep trying the download screen thing
Sorry if this is in the wrong section but I guessed it could go here because I need some files....
flash Eugene's froyo that does not brick via Odin. he has instructions in his thread.
...and it's kernel NOT kernal people
Sent from my SGH-T959 using XDA App
kernel, sorry I guess?
Anyhow what if my pc doesnt notice the phone when its in download mode

Download the Samsung drivers, download ODIN, and then just follow the directions in the ODIN thread
Wow
You guys have nothing better to do than flame a newb?
If you spent half the time helping instead of flaming there MIGHT just be some people with a bit more knowledge than they had yesterday.
If you cant say something constructive/helpful --Why bother!

Push doesnt seem to work. Permission denied or something rather.
As I said in my first odin wont work, yes I did those things like 10 or so times.
You cant expect a newborn to know how to wipe themselves.

What do you mean "push doesn't work". Are you trying to push a file via adb? If you are getting permission denied errors, that is because you either do not have root access/permissions to write to the location you are trying to push to, or because the location you are trying to push to is mounted as read-only.
If you indeed have the necessary permissions (i.e., root), then `adb remount` will re-mount the device's partitions as read-write. If adb does not allow you remount the partitions in this manner, it is because you do not have the permissions to perform the duty.
If anyone is going to give any further help, though, you need to give us a bit more information. Can you access the device via adb? Can you boot into either download or recovery? (If you have adb access, you can usually boot into either of those with `adb shell reboot download` or `adb shell reboot recovery`.) Have you attempted to flash anything via Odin? What is the exact wording of the error messages you are receiving?
If you don't provide information, you won't receive any help. Vague responses such as "Permission denied or something rather" are useless because something rather can be any number of things. Also, attempting things without reading all of the information available beforehand is another way to ensure that people will be hesitant to give you help; this forum already has threads about where to locate the stock kernel image.
Also, instead of positing what-ifs such as "Anyhow what if my pc doesnt notice the phone when its in download mode", why don't you try putting your device into download mode and attaching it to a Windows computer with the proper drivers installed and Odin running, and then ask what the next step might be after you have attempted to do something?
People get angry about members flaming newbies for posting mistakes and asking for help, but if newbies looked for answers and read all of the information available before doing something they didn't understand (or only partially understood), then this wouldn't be a problem in the first place.

Goalush Clockwork Recovery so I can flash Bionix.
What Happens:
1. Go into recovery
2. Connect to the phone with adb
3. I type 'adb push c:\update.zip /sdcard'
4. It says 'failed to copy `c:\update.zip` to `/sdcard/update.zip` : Permission denied
I type 'adb remount' its says ' remount failed: No such file or directory

Yes, I can get into both.
I've download Froyo that doesnt brick. Unziped and got had the drivers from sansumg set up.
I usually type 'adb reboot download' to get into download mode for odin. Then when the phone shows the android guy with the shovel. Then my computer says that an unrecognized usb device has been connect.
This time I type 'adb shell reboot recovery' and its said
'-exce `/system/bin/sh` failed: No such file or directory (2) -'

You have to be rooted.. But why would you even take the hard way to use clockwork? Just download it from the market..?
I have odin with all the files that will get u to stock of ur phone. Also the froyo files does not brick. So now i exactly dont know what u need. go cows
I messed up my phone and its stuck in a bootloop. I want to put that recovery on my phone so I can flash a new rom.

OK, if `adb remount` isn't working properly, then you have to manually instruct the system to remount the system partition as read-write. This is a little different from other Android devices, because Samsung insists on using their screwy RFS. On my device, the system partition resides at /dev/block/st19. If you can get an adb shell session, opened, you can verify it by running `mount`, and seeing which /dev node is assigned to /system. Then, manually remount the system partition with `mount -o remount,rw -t rfs /dev/block/st19 /system`; this must be done as root.
It does seem a bit odd that you are getting a permission denied error on /sdcard. Are you sure that /sdcard is mounted? You can verify the same way you check what /dev node holds you system partition. On my Vibrant, /sdcard is the mount point for /dev/block//vold/179:1 (yes, that is two slashes after block). So, the command to mount the internal SD card is `mount -o remount,rw -t vfat /dev/block//vold/179:1 /sdcard`.
Now those commands should ensure that you have both your system partition and SD card mounted as read-write. Now you can copy over the update.zip that contains ClockworkMod recovery to the root of your SD card (/sdcard) with `adb push drive:\path\to\recovery.zip /sdcard/update.zip`. I recommend specifying a destination filename for update.zip. Also, sometimes an adb push command requires the trailing / of a directory.

This last statement looks like either your system partition is not mounted, or that it does not have a shell installed. From an adb shell session, check the /system/bin directory and see if there is indeed a shell binary there (either sh itself, or sh linked to another shell such as bash). If there is no /system, then it means that your system partition is not mounted, and you can follow the steps I previously mentioned to mount the system partition.

Can you boot into recovery using the VOL_DN and POWER method, or does the adb daemon ever come online during the bootloop? If so, then either boot into recovery from a powered-off state, or use the adb shell to boot it into recovery.

I tried 'adb root' and then it said 'adbd cannot run as root in production builds'
By shell session do you mean 'adb shell'? No, I dont believe that works because I get 'adbd cannot run as root in production builds'
When you mean 'shell installed' you do I have it installed on the phone? If it isnt is there anyway I could do it now?
`adb push drive:\path\to\recovery.zip /sdcard/update.zip` didnt work and gave me 'c:\update.zip' to '/sdcard/update.zip': Permission denied
Can I flash /system via my pc onto my phone? or Use the external sdcard instead of the internal?
Dude, if your phone is stuck in a bootloop, you HAVE TO FLASH IT VIA ODIN. There's no other work-around.

Why did you try `adb root`? I don't quite understand that.
A shell session would be `adb shell`, yes. On your computer's command line, invoke `adb shell`. You are now in a shell session. What does the prompt look like? Is it "#" or "$". If it is a hash, then you have root access via adb. If it is a dollar sign, then you do not have root access; try running `su` from within the shell session. If the prompt does not change to a hash, then you are stuck for the moment, because you do not have root access via adb, and therefore nearly all of the adb commands will not work.
By "shell installed" I was referring to a shell interpreter installed on your handset. bash is the most commonly installed Linux shell, and sh is usually just a pointer to bash. If your handset does not have either /system/bin/sh or /system/bin/bash (or anything similar), then you have an incomplete system, and it got messed up along the way with something you did.
But, since it seems that you cannot gain root access through adb, and therefore cannot (re)mount your partitions, you are basically limited in your options. All you can really do is put your phone in download mode, and use Odin to reflash a complete system (including a kernel image). I would also recommend that you use the repartition option in Odin to make sure that your partitions are reformatted and you are essentially left with a wiped and clean handest to start with.
(Lack of root access via adb has severely limited your options. You are basically left with Odin as your only avenue of recourse, unless you are willing to disassemble your device to get to the internal SD card.)
Have you opened yours? Is it an actual (micro) sdcard that can be taken out like the external one?
I typed 'adb root because typing 'adb' showed this
adb root - restarts the adbd daemon with root permissions
so I guess that was what you ment by root.
When I type 'adb shell' all it gave was - exec '/system/bin/sh' failed: No such file or directory (2) -
You need to stop trying to do it the hard way and just use Odin. If your phone is not being recognized then you need the correct drivers. Once installed, you should be back up and running within 5 minutes. Stop lollygagging and fix your phone already.

[How-To] Retrieve your Original Serial Number

This was purely experimental for me, but it worked. And now I have my serial number back.
Pre-requisites:
1. You need CWM, running internal, or at least two microSD cards to be running from sd card.
2. Two MicroSD card required.
3. If you're using Windows you need some program that can perform disk dumps. I use Ubuntu... so... I don't know if the commands are similar in windows, sorry.
4. You'll need someone else' serial number. In other words, you'll need someone else' backup of the /rom partition. Check lavero.burgos unbrick topic. I think there is one on there.
This should be at least somewhat risk-free. Since it doesn't actually tinker with settings
Okay, so boot into internal cwm on your Nook. Make sure you have an sdcard in your nook. Then run adb:
Code:
$ adb start-server
$ adb devices
Make sure you see your device and it shows it in recovery mode.
Code:
$ adb shell
~ # mount sdcard
~ # dd if=/dev/block/mmcblk0p5 of=/sdcard/blk/mmcblk0p5.img
~ # exit
$ adb pull /sdcard/blk/mmcblk0p5.img /path/to/file/mmcblk0p5.img
$ adb shell
~ # rm /sdcard/blk/mmcblk0p5.img
~ # exit
At this point you insert your sdcard into your computer. Depending on what adapter you use, we need to make sure that you are going to use the correct device... so...
Code:
$ fdisk -l
Other than your Hard Disk's partitions (usually the first four), you should see a second one, either /dev/mmcblk0 or /dev/sdc depending on the adapter, but make sure it is the same size as your SD card, so you know which one you are going to be using. Once you verify which one is yours go ahead and umount it.
Code:
$ dd if=/path/to/file/mmcblk0p5.img of=/dev/mmcblk0
Wait for it to finish, shouldn't take longer than a half-minute, once it's done, Go ahead and mount it again, you should see the only partition as "rom", and two folders: devconf, and log.
Navigate to devconf, and there's a bunch of other files. Open "DeviceID" in vim or notepad or something. This is your Serial No., or where it should be anyway. On your nook, if you pop open the little MicroSD flap, you will see the device' serial number. Delete whats in that file, and type your Serial No. on there. Close and don't forget to save it. Now open "SerialNumber" and delete what's on there, and key in YOUR serial number. Close and save.
Umount your sdcard again. Delete the original mmcblk0p5 (/path/to/file/mmcblk0p5). Then jump into shell
Code:
$ dd if=/dev/mmcblk0 of=/path/to/file/mmcblk0p5
$ adb push /path/to/file/mmcblk0p5 /sdcard/blk
$ adb shell
# ~ dd if=/sdcard/blk/mmcblk0p5 of=/dev/block/mmcblk0p5
# ~ umount /sdcard
# ~ exit
In cwm go into advanced/reboot recovery. Let it reboot. And then when it's in cwm run "adb devices" and verify your serial number is there.
Thanks to Pete1612 and lavero.burgos ! Hopefully Pete1612 will test out this method too. This should be relatively easy, it's not hard. Just time consuming. -_-
Once again, let me know if I made any mistake
I will as soon as I get the I/O error figured out

The I/O error means the partition is damaged, however when unmounted the sdcard and re-inserted it, it seemed to work fine, so I went with it.
I took a different SD card and it worked.

I think have a way:
1. Copy mmcblk0p5 from nook tablet fine and push to sdcard
2. Use dd command
dd if=/sdcard/blk/mmcblk0p5 of=/dev/block/mmcblk0p5
3. In Cm7 ( boot sdcard) or stock rom have root, i use root exploer change serial in file devices id, serialnumber in rom/devconf.
I had changed my nook by this way. It success, it pass b&n :0
a much easier method... from any rooted nook with ADBD enabled.
Get either adb shell or a terminal and change to root user by issuing the "su" command.
copypasta this block
Code:
mkdir /data/local/mnt
mount /dev/block/mmcblk0p4 /data/local/mnt
Serial=`cat /data/local/mnt/devconf/SerialNumber`
echo "Your Nook Tablet Serial Number is: $Serial"
You will receive a message that says "Your Nook Tablet Serial Number is: ************"
OP is convoluted.

OP has made a guide to restore it.
Yours is a way to print it out *if* its there, anyone can read it under the sd card latch so i dont see your reasoning of this post.
Hello, Can you help a noob with this ? I am at a command prompt. Wrong serial # Recovery
now what exactly ? Thanks
Hey I'm not sure if this is right, but can't you just lift up the tab where the sd card goes? It says SN: followed by a bunch of numbers.
When I needed a new charging cable, they asked for the serial number, and I just read it from there.
Sorry if this isn't what you guys are talking about, just thought I'd post.

the thread is to recover a sn that is MIA or incorrect for the nook in use. Some have lost their sn (no longer in nt) or replace an incorrect sn with the correct sn.
What if you can't see your NOOK TABLET?
My problem here is I can't get my computer to see the NT. When I update the drivers, it brings it up as an android phone and under that says "Android Composite ADB Interface". Any help. I think I might have completely screwed this up.
I realize this thread is old but I've been trying to go through the process. My first question is how large does the mmcblk0p5 get when you dd it? I was using a 2gb SD and the file took up 2gb then. My second question is if anyone knows how to complete the final push back to the SD card in the nook. It begins to push but after some time the nook screen flashes and it seems to hang. Thanks in advance.
Just use es explorer with root privileges heh.
So would I just copy the file to the sdcard, then once that's done transfer the card back to the nook, and use the es explorer? I'm not quite sure how to do exactly what you stated.
Boot rom , open es give root rights go to / rom find file edit it onthefly, save reboot done

Really, it's that simple? Wow, and I was working through all this last night!

[Q] No media audio, system or notification sounds work.

Hi guys,
I don't know what piece of info is relevant or not, so I will outline as much as I can.
I was running the latest stable Slimbean with stock kernel, a couple of weeks ago my external sdcard stopped being recognized and would not mount. In Clockworkmod it would show an error mounting what I later learned were 3 different partitions.
Yesterday I installed freegee to try and restore my original partitions, but it would give me an error that my device was not supported. So I uninstalled freegee. The next time I rebooted my phone, it would get stuck on a black screen after the LG logo. I was able to get into recovery and download mode, so I tried the original teenybin with lgpnst and I could not get into recovery, only the LG logo. I then tried the alternate teenybin that boots up with the Google logo and I was able to get into TWRP.
I then sideloaded Houston's aosp KitKat and was able to successfully boot up the phone. I now have no system sounds, no music or media sounds, through the speaker or the headphone jack. Phone audio works through earpiece, speaker and headphones.
Tried wiping and reflashing. I don't know what else to do.
Any ideas would be appreciated.
Thanks.
I also noticed that sensors were not working.
I flashed the W84C27MO84.zip hybrid modem.
This solved the problem with sounds and audio not working and fixed the sensors.
Post your partition table here!!!
Enter in CWM Recovery, connect your phone to computer, open terminal in administrator mode. open adb shell and run this command.
parted /dev/block/mmcblk0
press P and put your result partition screenshot here.

I wasn't able to do it exactly as you described, but I think I got what you asked for. Hope it helps.
Thanks,
Im so sorry my steps was with Special CWM.
Try this 3 steps on ADB shell.
Code:
dd if=/dev/block/mmcblk0p17 of=/sdcard/mmcblk0p17.bak
mke2fs -T ext4 /dev/block/mmcblk0p17
reboot
good luck!!

Thank you for the response.
What exactly will this do?
I ran what you suggested.
I received "Not enough space to build proposed file system while setting up superblock"
How much free space is required? I have almost 2gigs free
you need to do separate steps. One line is one command. Enter every one line.
And Dont copy paste i see another extra simbols

Hello,
Thank you for your responses.
I tried doing it again, one line at a time, but still got the same message after the second line.
Try add -F to the second line like this:
mke2fs -F -T ext4 /dev/block/mmcblk0p17

[HOWTO] Unbrick your device

This unbricking method requires that you have adb working and have root access.
First, download the latest system update for your device.
For the 7" HDX, they are posted at
http://www.amazon.com/gp/help/customer/display.html?nodeId=201357190.
For the 8.9" HDX, they are posted at
http://www.amazon.com/gp/help/customer/display.html/ref=hp_left_v4_sib?ie=UTF8&nodeId=201357220.
Now, please note that I DO NOT have a Kindle Fire HDX, so if this doesn't work, let me know and I will remove it immediately.
Try these commands:
Code:
adb shell
su
mount -o rw,remount /cache
mkdir /cache/recovery
echo install /cache/kindleupdate.bin > /cache/recovery/openrecoveryscript
chmod 0777 /cache/recovery/openrecoveryscript
exit
exit
adb push your-downloaded-update.bin /cache/kindleupdate.bin
adb reboot recovery
The only thing that you have to do is replace "your-downloaded-update.bin" with the path to your downloaded update. (To make it easier and avoid typos, I always just drag and drop the file into the terminal/command prompt window.)
Please also note that IT IS OKAY if the command "mkdir /cache/recovery" fails, as long as the error message says file already exists or something along those lines.

Sorry, Im slightly confused, how are we able to fix the device with ADB if it is bricked? Mine will not get past the white "Kindle Fire" page, any ideas?

I transfered a stock Rom through ADB but It failed while flashing... because there was some kinda problem with Cache partition... so i tried your method and it worked... but i made a little change in last Commands... I gave it "EXIT" command only 1 time and did not give the command "ADB reboot Recovery"... I recommend you guys to manually boot to safestrap recovery after quitting CMD.... Ahhh my device is Kindle Fire HDX 7"
root not required?
Thanks, r3pwn, this works well. Nice, easy instructions that should be instructive to anybody messing with their device.
This helped me after a botched update to newer Amazon firmware. Quick question though: It seems like you don't really need to be root / use su to do these steps. I had lost su in that update but was able to execute the rest of the adb commands without root. I guess that should be the same for anyone who doesn't have root, right?

No, sorry, I don't even have this device. There are newer, better ways to unbrick now.
I think trying to find eMMC pointer
i have tried this.. but when rebooting it takes me back to recovery menu with 2 options.
1. reboot
2.reset
whichever i chose, still takes me back to boot loop (animated logo)
any ideas?
does this method require TWRP? As i cant get this working..

Unbricking Apollo: Can I pause bootloop so I can finish .bin transfer over ADB?

I have a soft bricked HDX 8.9 Apollo. I've scoured dozens of threads about unbricking my Apollo device and I feel fairly confident I could unbrick my device if I could just keep my device on long enough to transfer my ~600MB rom, but my device only has ADB (with root) access for about 45 seconds before it reboots, interrupting my file transfer (getting "Connection reset by peer" transfer error when the device resets).
- I can boot to recovery and fastboot modes which stops the boot loop, but I don't have ADB access in either of these modes.
- I've tried "adb -d shell stop" (which is a command I've seen used to stop a boot loop on other devices) but this does not prevent the boot loop.
Surprisingly no one in any of the threads I checked mentioned a similar problem so I guess I'll just ask here. I can give details if you want but really I just need to know if there's any way I can pause the boot loop while maintaining ADB access and I should be able to handle the rest.

No clue what you're trying to do. I'll throw this out, use the Terminal found in recovery mode.

With all the necessary files along with the commands ready to copy and paste, you could replace recovery (if needed), aboot, and unlock the bootloader in 45 seconds or less. Boot into recovery and flash whatever you wanted to. Other options you could look into are bulk mode and 1-Click.

Absolutely agree. Forget the dated unbrick threads. Use 1-click or manually replace the bootloader and recovery. If pursuing the latter don't worry about immediately unlocking; that can be done later after device is stable.

Sorry for the limited info, but I can offer more clarity now that I have more time. Basically I soft-bricked an Apollo back in 2015 by accidentally flashing a rom designed for Safestrap v4 onto Safestrap 3.75. The last thing I had done before flashing the rom was I rolled back to 3.2.8 and towelrooted it. At the time I declared it a loss.
So yeah I guess I need to replace the bootloader and recovery. I don't have access to a linux or mac machine atm, so I guess I'll be doing this manually.
I was able to get my unlock file and and push twrp and aboot to /sdcard/ just fine, and it looks like I was able to get superuser in adb shell.
Code:
C:\ADB>adb shell
[email protected]:/ $ su
255|[email protected]:/ $ I have SU now right?
but when I run
Code:
255|[email protected]:/ $ dd if=/sdcard/twrp_cubed.img of=/dev/block/platform/msm_sdcc.1/by-name/recovery
it returns
Code:
/dev/block/platform/msm_sdcc.1/by-name/recovery: cannot open for write: Permission denied
Do I need to change folder permissions to be able to execute this? If so, how do I do this?
EDIT: Oh I just realized I guess 255 isn't SU? Seems strange that the su command is going through without error if I don't have root access.
It looks like the one-click bootloader unlock method does not require root. Is there a way to accomplish a rootless unlock without one-click?

Thanks for the tip! Unfortunately I do not have access to the filesystem via windows, I can only copy files over via ADB. So unless there's some way to gain access to the filesystem with an ADB command I'm probably sunk there
So that's it then I presume?

Nope. There's usually a way if the HDX boots into recovery or bootloader. If recovery is twrp and not stock, it may be possible to issues the commands to replace aboot via the Terminal. It's not ideal, but may work. I think you really need to take another look at Bulk Mode. Follow the instructions very carefully or you will be out of luck. If you have any doubts, don't attempt using Bulk Mode.

I guess I should have clarified, I don't have twrp, I only have access to stock recovery. If I had twrp running I probably wouldn't be here lol.
Unless there is another thread that explains how to use this "Bulk Mode" without access to the tablet's filesystem in Windows, in the guide linked above, the very first step is to pull the diskindex from the drive as it appears in Windows. Obviously this will fail because it is not mounted, but here is the result with the tablet connected and ADB working anyway:
Code:
C:\ADB>wmic partition where index=22 get diskindex
No Instance(s) Available.
C:\ADB>wmic partition where (index=17 and numberofblocks=20480) get diskindex
No Instance(s) Available.
C:\ADB>wmic partition where (index=5 and numberofblocks=4096) get diskindex
No Instance(s) Available.
Without a diskindex reference to the tablet's drive, I can't proceed to the next step to copy twrp and aboot into the recovery folder. And as far as I can tell I don't have root anymore so I can't do it via ADB.
So I would assume I'm dead in the water here since as far as I can tell I don't have any access to the folders I need to place the files in? Unless I can like directly sideload them or something. I have virtually nothing to lose here so I'll try whatever.
Just to clarify, I definitely don't have root? What exactly does it mean if the "su" command does not throw an error but instead returns "255|[email protected]:/ $" ?
Code:
C:\ADB>adb shell
[email protected]:/ $ su
255|[email protected]:/ $ In what way did my permissions change here?

Your best bet is to use 1-Click. 1-Click basically does the same thing as Bulk Mode, but does it automatically for you. Bulk Mode hint - bootloader.

Does 1-click not require USB access to the filesystem or root access? I guess I could install and run linux on a flash drive just to test this but it would be nice to know if the interface to the device is likely to work, I don't know anything about VirtualBox. If we're not sure I'll probably try it later.
