Help!! messed up updating cyanogenmod! Bricked??

I really need some help please! I think I may have done something very bad. I have a tmobile mytouch 3g. I was trying to update from cyanogenmod 4.2.1.9. I was using a darkstar theme from ringer nation.
Here’s where I think i screwed myself. I am fairly new to all this stuff so I was trying to find a guide on how to update the mod and instead of doing it properly by adding the files to the sd card, doing a wipe, and then installing everything. I instead messed up and did an install of sapping.nbh and basically followed all the directions to originally root the phone. Including formatting the sd card and everything. When I realized that i was doing this all wrong I was still able to load my os and everything seemed ok. I was getting a sd card error that said that the card was blank or had an unsupported file system, but I was able to mount it so, I erased everything off the card and then put the cyanogen update and the drc83_base file and attempted to load into recovery and do the update.
I loaded into and did a wipe. I attempted to follow the instructions on upgrading from the cyogen page. (God I wish I had found that page first) But after I did the wipe and I attempt to Apply any from SD I get “error: sd card is not mounted”
When I attempt to reboot the phone it goes to the tmobile mytouch logo, THEN it goes to my them logo from Ringer Nation, then it just goes to a black screen I let it sit there for like 5 minutes to see what would happen, but nothing. So I took out the battery and sim. I can get into recovery though so I hope that someone can help me figure out where to go from there.I thought that since I had done a wipe that the theme would have been deleted as well? This is weird.
I did do a nandroid backup before. Hopefully that will prove to be helpful. Sorry for the long post, but I wanted to dump as much useful information about this problem so that hopefully someone will be able to help! BTW I'm using a mac with the latest snow leopard software.
As I am desperate for help, please reach out to me via aim – icolinirie or via email
Thank you in advance for everything. This is a great community, and all of Cyanogen’s work is greatly appreciated!!
EDIT: I really need some help! Here's some more information. I have a Magic 32B. Its running Cyanogenmod v1.4 + JF Recovery.
From what I have gathered I need to adp into my phone in order to get it to mount. Anyone know how to do this on a mac. I am trying, but I don't fully understand. I have created the .bash_profile from terminal and typed the following "export PATH=${PATH}:/Users/itunes/Documents/android-sdk-mac_86/tools" which is the path to the tools file in the sdk. I am just stuck at this point. I don't know what to do from here.

Hi I quote.
Install SDK utilities you need to connect your PC to your phone
You can download the full SDK from the Android Developer website for your platform
http://developer.android.com/sdk/index.html
You'll need to download the SDK appropriate for your platform and extract it into a directory somewhere. I'm going to assume you're using Windows here and suggest you extract it into a folder called
C:\AndroidSDK\
on your hard disk. You can put it anywhere you like really, but if you do you'll need to substitute it for the folder above.
Add the tools directory to your system path for easy access
In Windows it's easy to add the Android SDK Tools directory to your system path. Doing this lets you use the Android SDK tools anywhere and makes it easier for you.
On Windows XP: Go to Control Panel->System, Choose the 'Advanced' tab and then click 'Environment Variables' To do this on Vista/Windows7: Simply go to Control Panel->System and choose 'Advanced System Settings' and then 'Environment Variables'
Now that you've got here locate Path under System Variables and click Edit, then add the following to the end of the string displayed:
;C:\AndroidSDK\tools\
Then click OK until you get out of the menus.
Now that you've done this you should be able to bring up a command shell and type 'adb' and it should run straight away without needing to change path.
Please note that you can skip this step completely if you find it too complicated - however you will need to CD to the ?AndroidSDK\tools every time you open up a command prompt so it's worthwhile doing. I'm going to assume you have made the change above in all further examples as it gets too complicated really. If you're not confident in a DOS shell, I'd suggest you do a little bit of reading up on basic navigation in DOS first.
Enable Debugging mode on the phone before connecting to PC and installing the ADB driver
Menu > Settings > Applications > Developement > USB Debugging
Install the USB drivers correctly - check using "adb devices".
If you have already connected your phone to your computer before then the USB drivers are probably already loaded. If you're lucky then typing 'adb devices' in a command prompt will produce something like:
C:\AndroidSDK>adb devices
List of devices attached
XXXXXXXXXXXX device
Where XXXXXXXXXXXX is the serial number of your phone. If it doesn't produce that line, then you need to check Device Manager and ensure the device drivers for your phone were installed correctly.
If you are having issues installing the ADB driver, you need to connect your phone then go into Device Manager and check the ADB device properties. Check the following property and it'll look something like:
Device Instance Id: USB\VID_0BB4&PID_0C02&MI_01\7&293A7D0D&0&0001
To fix the driver installation problem, you need to edit the driver's .ini file and change all the references of 0C03 to 0C02, or 0C02 to 0C03 if your device property states your Device Id is 0C03.
Note: After flashing a new ROM, your Device Id may change again to either 0C03 or remain as 0C02. So you need to update the .ini file again as above to refelect the change and re-install the driver. Another known way to fix the above issue is to download and install HTC Sync - this seems to install the correct drivers.
How to use ADB
ADB stands for Android Debugging Bridge - it's a useful way of talking to your handset while it's running. ADB provides commands for copying files to and from your phone, installing packages and debugging your Android applications.
Useful commands include:
adb devices - lists which devices are currently attached to your computer
adb install <packagename.apk> - lets you install an Android application on your phone
adb remount - Remounts your system in write mode - this lets you alter system files on your phone using ADB
adb push <localfile> <location on your phone> - lets you upload files to your phones filesystem
adb pull <location on your phone> <localfile> - lets you download files off your phones filesystem
adb logcat - starts dumping debugging information from your handset to the console - useful for debugging your apps
adb shell <command> - drops you into a basic linux command shell on your phone with no parameters, or lets you run commands directly
How to use Fastboot
Fastboot is another boot method and is used to drop the phone into a safe mode to load/flash alternate roms. You need USB debugging turned on before you can use Fastboot mode - so I'd recommend you do this first (under Settings->Applications->Development->USB Debugging). You will also need to power off your phone first (hold down Power and select Power Off) and then hold down the Back+Power Buttons to start the phone in Fastboot mode. You will need your USB cable connected to be able to issue any commands and assuming your drivers are correct you should be able to issue:
C:\AndroidSDK>fastboot devices
List of devices attached
XXXXXXXXXXXX fastboot
Other commands in this mode include - we'll cover these below in subsequent sections.
fastboot boot <filename> - boots a rom stored on your pc specified by the filename
fastboot flash <partition> <filename> - flashes a rom stored on your pc, partition can be one of {boot, recovery, system, userdata}
fastboot binaries for mac and linux can be found here.
3. Learn how to use fastboot and boot a recovery rom
Download a recovery rom for your device
There are several different recovery roms available for the HTC Magic devices.
Amon_RA has created several nice recovery roms available from http://forum.xda-developers.com/showthread.php?t=530492 and get the Recovery Rom appropriate for your device - these recovery roms have Nandroid Backup and Nandroid Restore and are perfect for the average user.
You can also use Cyanogen's 1.3.1 Recovery ROM available for: PVT32A devices and PVT32B devices - this rom has some additional options for partitioning your SD card for ?Apps2SD/Swapper/etc.
Fastboot the recovery rom
Fastbooting a rom doesn't write anything to your device - it just loads it directly from your PC - so it's a completely safe way of fixing/recovering/backing up your existing rom. To fastboot a rom you need to first drop your phone into Fastboot mode and check that it's working. Now drop into a command shell and make sure the recovery image you're wanting to load is in the same directory that you're running this in. If it's called something other than recovery-rom.img then substitute that instead.
C:\AndroidSDK> fastboot boot recovery-rom.img
If you are having problems changing the directory in the command prompt, just make a copy of the command prompt .exe itself, and place it in the folder that contains the recovery rom, then run the above command.
And once again, if you have a perfected SPL which does not allow remote fastboot, you will have to fix it first.
Use the Recovery Rom to Backup your current ROM with Nandroid
Once you've booted to a recovery rom - you can use the Nandroid Backup option. If you get a 'cannot mount /dev/mkblkxxx error' when you do this then check your microSD card is inserted correctly and if so, wait a few seconds for it to register to the recovery rom correctly. If at first you don't succeed, try, try again (sdcard can take a few seconds to mount!)
You do not need to be a rocket scientist to do this.
you can use the ADB to put in recovery again by fast boot

Hey! First off Thanks for the reply! I really appreciate someone chiming in to throw some advice my way! But while reading your thread you described the instructions for windows. In this case I have a macbook pro running snow leopard.
I did download the android sdk to my documents folder and I understand that I need to execute some scripts from the terminal on my mac to get things running. But I really dont know what those scripts are or what exactly to do.
I can get into the recovery mode on the MyTouch by holding power and home when powering on. So do I open the console from the recovery screen on the mytouch and then run the scripts on the terminal from my macbook? And which scripts should I run to get the sd card mounted onto my desktop (that is what I'm trying to do). Im not too sure what to do from there either. I want to get the phone back to stock android 1.5 os so that I can root again. My sd card has to be corrupted because it keeps giving me an error saying that it wont mount when I try to do a fix file systems or try anything from that menu. What to do??

What!
can you get in the recovery?

Yeah I can get into cyanogen v1.4 recovery. I'm just stuck from there.

Ok ok If I understand this correctly then you are not briced. you do not have any imag on your phone.
if you do not have anything nadroid recovery on sdcard you must enter a new ROM on the sdcard and flash it
remember full wipe.!

Yes this is what I believe I must do. But I need to either find a way to mount my SD card from the phone while it is in recovery mode (cyanogen v1.4). That's my problem.. I wish there was an easier way to get it mounted onto my mac from the recovery screen. I think I'm just going to go to best buy tomorrow and get a micro sd card reader and maybe another sd card just in case.
Once I have done that though. What files should I put onto the sd card in order to flash it back to original factory android 1.5.
What do you think?

Good idea
I have never used cyanogen v1.4 recovery
I use the recovery-RA-sapphire-v1.5.2H.img and ther you can use USB togle in recovery mode, You must go to the store to buy the adapter that fits on your Mac, I have two adapters for your Mac, you can borrow

Yeah that's the plan for tomorrow. Thanks for the offer man. But I'm in Los Angeles, Ca LOL!! Where are you?

Ubuntu LiveCD with ADB and Unrevoked Recovery installer(Guide).

I have been helping out with rooting HTC Aria's over in IRC in the #liberatedAria channel for a while now. A lot of people have problems with drivers on Windows. The easiest solution for them to do this has been to download an Ubuntu LiveCD and use it to root their phone, however many people know nothing about Linux at all and feel daunted by this.
I have created a customized Ubuntu LiveCD that has a script that downloads the Unrevoked Teams reflash, untars it, and runs it as root to root HTC's phones that are supported by the tool (HTC Evo, Hero, Aria, Desire, and Incredible). It also has the Android SDK included and added to the path so it is accessible from a terminal. Everything can be done without a single change to the computer you are doing it on.
Download the iso image here:
MD5: 9a34c343e8f610e66674af9384334bf6
ubuntu-10.04-desktop-i386-HTCROOT.iso Primary
ubuntu-10.04-desktop-i386-HTCROOT.iso FileFactory.com
Burn the iso to a cd (This can be done with any cd burning software, imgburn found here is free)
[Optional]
If you do not have a CD drive, you can create a bootable flash drive by using the tool found here:Pendrive Linux
Put the CD into your computer cd/dvd drive and reboot your computer.
You must make your computer boot from CD, there are many different ways to do this depending on what computer you have, most recent computers have this enabled by default. Here is a guide that may help if you can't get this to work:Enable Boot from CD
Once it boots from the cd it will show a small picture of a keyboard and a person, do not press anything here and it will come to a window that will allow you to select your language.
Select your language and click "Try Ubuntu 10.04 LTS". This will boot up to a standard Ubuntu livecd desktop.
On your phone click menu, settings, applications, development, usb debugging
On the computer click "Places" on the top menubar and click "Home Folder". This will open a file explorer window, in that window is a script called "reflash.sh".
Double click reflash.sh. A window will pop up asking you what to do with this file, click "Run in Terminal". This will go get from the internet the current version of Unrevoked recovery installer from unrevoked.com/recovery, unzip/tar it, and run it as root.
Once it is complete you will be looking at the unrevoked3 screen and you should follow the prompts on screen.
You will then follow the prompts on the screen to plug in your phone, from the notification pane in android select charge only.
unrevoked3 will reboot your phone twice and leave you in ClockworkMod Recovery. On the computer at the bottom of the window it will say "Done".
Close the window, if you do not need to do anything further you can shut down the machine and be back in windows with nothing changed on your windows system.
Congratulations, your phone is now rooted and has ClockworkMod recovery installed.
There are other guides to setup of sideloading for the aria as well as how to load roms. You can do these using this live cd as well, this is a full ubuntu 10.04 livecd with only games and open office removed, and the unrevoked3 installer and the android sdk installed, it is already in the path and you can use adb commands from the terminal without having to switch directories(however it can be found in /opt/android-sdk-linux_86).
I would like to thank The Unrevoked team for making such a nice tool, and website that made this possible. I would like to that the guys in IRC on Freenode.net channels #liberatedAria and #koush for everything I've learned recently as well as all the great work they have done. Thanks also to Attn1 for making some nice roms for the HTC Aria and gave me the idea to create this. Thanks to Downer3d for the torrent mirror. Thanks to Neolobster for the new faster mirror.
Allowing Non-Market Apps using this cd on the stock ARIA rom:
Click Applications in the upper left corner.
Go to Accessories, click Terminal. This will put in you a terminal in the default users home folder. Because ADB(and android sdk) are in the path you do not need to change any directories. Start the phone in CLockworkmod with data mounted from the partitions menu and plug the phone into the computer.
Code:
sudo su
adb pull /data/data/com.android.providers.settings/databases/settings.db settings.db
echo "update secure set value = 1 where name = 'install_non_market_apps';"|sqlite3 ./settings.db
adb push settings.db /data/data/com.android.providers.settings/databases/settings.db
adb reboot
What this does:
Switch user to root.
ADB pulls the file that contains the setting to allow non market apps down to the machine from the phone.
The next line runs a sql update of the field install_non_market_apps in table 'secure' and sets the value to 1 (on).
ADB then pushes the file back to the phone in its original location.
You then use ADB to reboot the phone to enable it.

Thats awesome!! If I didnt already go through all the trouble of doing it on my Windows box I would definitely try your live CD. I already have 10.04 installed on my laptop and I never really thought of trying it on there. I wonder if it would have been easier....oh well. Thanks again. Im sure there are plenty of people out there that will find this very useful.

Much easier. And yes, this IS awesome. Great job, Shad0wf0x. This kicks ass.

This is a fantastic idea, I had a ton of trouble rooting my Aria on Win7 x64 and downloading and using Ubuntu 10.04 eventually proved to be much easier. If your iso works as advertised I can see this possibly being the most pain-free solution for annoyed Windows rooters.
Sent from my HTC Liberty using XDA App

This works wonderfully for rooting and sideloading apps (the only issue there was figuring out I needed the root account and permissions). As painless as a dentist trip.
If I was to install Ubuntu from that LiveCD, would it still have the Android SDK on it or would I need to reinstall it? I like not having to cd to it.

the android sdk is installed on the livecd and in the path, you'll have it every time you boot up, the part the script downloads will be gone on a second boot(unrevoked.com's recovery installer)

Great job!
Do u think that u could add some other HTC devices, in the future?

Awesome, thanks!

The devices supported are the devices supported by the unrevoked3 tool, I am not part of their team, just trying to help out some windows users who have driver problems.

Has anyone created a virtual image of s full Android dev system? That would sure be handy!

it says in your signature you have 2.2 updated OTA, that must mean you have an evo, and those aren't supported by the unrevoked tool when running 2.2.

awesome shortcut for rooting phones, however I followed the steps and it is saying that the hero is not supported at this time? Did i do something wrong, I'm running 2.27.651.5

I've burned the the iso file to a cd but I'm not able to get the boot-up to work correctly..or to come up at all, when re-booting windows.

@lcw
When you boot, you will need to hit your bios and select your CD drive as a boot device. Then enjoy the ride - easy as falling off a bike.

I cannot get my dell d600 or d630 to boot. The CD spins but I get the message "No bootable device".
I verified that the ubunto_*HTCROOT.iso file 641,942 kb is the only file on the CD.
Can someone please help.

You're not supposed to burn the ISO file onto a disc as a file. You're supposed to burn the contents of the ISO to a disc.

I attempted to boot from the CD, I get the person/keyboard screen then i get the Ubuntu screen, then my computer goes black, any solutions?

This is the BEST way to root your Aria. Big props to everyone that helped create it. You guys are the best.

[Q] What's the micro usb port for?

Does anyone use the micro usb port? I have yet to find a use for it. I can't transfer files with it, charge with it nor are there any peripherals (that I know of) that can use it. I searched around but couldn't find much useful stuff on the port. All I found was this useless video:
**Ok I can't post the video because of more stupid forum rules but just go to youtube.com and append this after the url: /watch?v=1xBVu-IatDQ **
Anyway, if someone has ideas on how this port can be used I'm all ears... Thanks.
dq

It is a file transfer port. you plug a cable into it and into your PCs usb port. works like the ones on your phone.

Does it work for you? Because it doesn't for me. Nothing happens when I plug it into a computer. No automounting on the computer side or indication on the tablet that I can put it into "usb storage mode" like the 2.X Android versions do.

Computer OS? i just plugged it into my Win7 system and it was there instantly. 3.0 shows up as a media device, which allows both the tablet and the computer to talk to the sdcard at the same time. So you won't see a mount prompt on the tablet. BTW my Incredible2 is running 2.3 and also lets me access the SD card on it and the computer at the same time.

I'm still using an old tiny xp and it worked fine for me just plugged it in and there it was

I tried Gentoo Linux and XP and neither worked. What drivers do I need to install?
I also have access to a Win7 system so I'll try that.
dq

Drivers from acer website.

I have adb installed should this not be enough?

You need none installed. ADB if its running in some form might be interfering. its just a basic driver in windows it uses.

I only run adb-server when I need it and not all the time. I thought that any needed drivers would have been installed when I installed adb.
For my Gentoo machine what should I do? It's not detected at all if I plug it in. My x10 mini and Nexus One are detected no problem and I can mount them and everything so what's up? Is there a kernel module that I need to build?
Thanks.

I had to download these drivers for my xp netbook ,,
http://global-download.acer.com/GDF...A Tab&Step3=A500&OS=a05&LC=en&BC=Acer&SC=PA_6

I agree with Nova 5. The Windows drivers for USB come with the SDK and while you might not think you will have use for the SDK you will. It makes the process of installing custom ROM,s and Recovery Kernels a breeze. You download your zip flashes or recovery images to Win 7 and then you adb push your downloads to the tablet. The alternatives, unless soneone was nice enough to compile you an apk, which most advanced system developers don,t bother with, unless their app is destined for the massees throug Andriod market, is to install a terminal emulator and enter native Unix/Linux shell commands manually. If you aren't a shell cmd expert I suggest you immediatly download the latest Android SDK for Windows and start learning what it can do for you with just 2 or 3 adb push commands which can help you advoid 10's of lines of manually entered Linux shell commands that can do some real damage to your system if you are copying someone elses terminal emulator sh install instructions, don't understand what they do and make 1 simple typing mistake. With adb push you don't even have to get involved in Linux's complicated bit based permission changes to install something at the system level.

Yes, well I only really use adb in the same capacity as what you describe-- to root a device. After that busybox can be installed and I can either ssh into the device (which I prefer) or use the terminal on the device itself.
But my problem is the detection of the device once it is plugged into my Linux box. I'm not sure if I need a special driver for that and I'd rather not aimlessly search through the kernel config in order to build one (I've done that before and it's painful!). It's good to know that one can mount it on an external device and still use it simultaneously though. That will save me time in trying to fiddle around with settings in the tablet itself...

If you are not able to transfer files Try enabling usb debugging before connecting to pc.

If the tab is not in the usb devices list and it doesn't show up as an unknown device, you might want to try another usb cable. Or another port if you have the Windows and Linux on the same machine and you are trying to connect on the same port.

Not nearly what I was saying. Not even close enough that a bomb would touch it.
Simple answer is my vista and win7 systems accessed the iconia as a media player device requiring no drivers as they are a common system driver. My only comment about ADB was that it might be interfering if it somehow was left running in the background.

I'm not sure what the problem is, but I had to play around with the settings and plug it in several times and finally it showed up. Now I plug it in and the dialog for auto play shows up instantly. When I choose to view files, I get a window with two drives. One is the internal storage and the other is the sd card.

Sometimes mine gets a bit wonky as well. Every now and then, I'll plug it in, get the windows dialogue box asking me what I want to do. I open it up and the box is blank, no drives, nothing. Unplug it, wait a few seconds, pop it back in, and everything is OK. No rhyme or reason, and it doesn't happen all the time.

Quick trick for win7 .
Plug in the device.go into device manager delete its entry and the USB controller it resides on.unplug device.install driver from acer web site.then try the device again.
This works on several USB type issues
Good luck if you don't understand don't try

U8800 + Linux + CWM

I have been a Linux user since Redhat 7.x yet this blasted phone is kicking my assets. Perhaps this is because many solutions are based on connecting a Linux phone to a Windows computer. I installed Win7 to a virtual machine. It sees every other device on USB except for this phone so no help there.
What I am trying to do - from Froyo - is a Nandroid backup which presumably requires CWM. Apparently, the only way to install CWM is through ROM Manager??
I can temp. root the phone. ROM Manager sees a different Huawei and then responds with a privileges issue. I know that I am rooted because, through adb shell I am getting a "#" prompt.
Oh, I am running Fedora 17. I have installed android-tools which includes adb and fastboot. Booting to purple/pink and plugging in USB seems to mount the entire phone (other than the SD card) in Dolphin. I suppose that I could copy the entire phone to the SD card but then how would I use those files to restore?
Ultimately, my objective is to install Aurora with the ability to restore the thing if necessary.

What I am trying to do - from Froyo - is a Nandroid backup which presumably requires CWM. Apparently, the only way to install CWM is through ROM Manager??

You can install CWM in pink screen by replacing recovery.img file.

[Q] DUAL BOOT UBUNTU And JELLY BEAN AND GUIDE

hey guys, for those that havnt seen it today Ubuntu has been released for the Nexus 7 and for both 8GB and 16GB Models! wondering if anyone in the community has figured out how to dual boot it or if it is even possible? thanks all!
Heres the link of how to install if your wondering
What you will need:
Nexus 7 Tablet (8GB or 16GB)
Standard MicroUSB Cable (should come with the device)
Ubuntu Nexus 7 Desktop Installer installed on your development system
Ubuntu 12.04 LTS or Later
Optional
Micro USB Host Cable (OTG Cable) - used for attaching keyboard, mouse, etc. Directions on how to get and use one of these are towards the bottom of this page.
Ubuntu Nexus 7 Desktop Installer
A simple one-click installer has been provided, and is available in a PPA.
sudo add-apt-repository ppa:ubuntu-nexus7/ubuntu-nexus7-installer
sudo apt-get update
sudo apt-get install ubuntu-nexus7-installer
Usage instructions for the installer are provided below.
Unlocking the Nexus 7
The Nexus 7 ships with a locked bootloader. You must unlock it in order to flash different images to the device. Fortunately, this is a trivial process, and you only need to do it once.
Warning: Unlocking the bootloader erases all data and resets the device to factory defaults.
Reboot the Android device into the Android boot loader. To do this, hold the volume down button and press the power button. Continue holding the volume down and power buttons until you see the boot loader UI. The device now displays the boot loader GUI, which looks like this:
Verify fastboot lists the device:
$ sudo fastboot devices
1234567891234567 fastboot
Start the bootloader unlock process:
sudo fastboot oem unlock
You are prompted on screen to unlock the bootloader on the Android device screen. Follow the on-screen directions to continue. Your screen should now look like this:
Complete the process by rebooting:
sudo fastboot reboot-bootloader
Or simply press the power button.
Installing Ubuntu on Nexus 7
Once all setup has been completed, the installation can start. To install, ensure the Nexus 7 is in fastboot mode, plug it into your computer (and make sure NO OTHER DEVICES are plugged in).
Find the installer in the dash (search for 'nexus'):
This will provide a Graphical Interface for installing Ubuntu. This tool will download the latest image automatically, and flash it accordingly. The flashing step should take about 2 minutes. Once the flashing is complete, the device will reboot and finish the installation. This step can take 10-15 minutes.
Returning your Nexus 7 to Stock Android
Warning: Disconnect ALL other mobile devices connected from your computer or they might get erased too. This will erase ALL DATA on your Nexus 7.
In case anything happens while developing, the system image for Nexus 7 can be found here: https://dl.google.com/dl/android/aosp/nakasi-jro03d-factory-e102ba72.tgz
After downloading the above tarball, uncompress it with the following:
tar zxvf nakasi-jro03d-factory-e102ba72.tgz
Then, place your machine into fastboot mode and run the resulting script:
cd nakasi-jro03d/
sudo ./flash-all.sh
You may get the following warnings, which you can ignore, the restoration will continue anyway.
archive does not contain 'boot.sig'
archive does not contain 'recovery.sig'
archive does not contain 'system.sig'
Troubleshooting the Install
If you have problems installing the image, please use the following troubleshooting steps:
Detach the USB cable, restart the tablet back into fastboot mode, and re-attach the USB cable.
If problems persist, reboot your host PC.
If you still have issues, try a different USB cable.
If you have a 16G tablet, try using the 8G image.
If you still have issues after doing all this, return the image to stock using the directions above and re-try.
If none of that works, ask a question on Ask Ubuntu using the mobile tag, or ask for help in the #ubuntu-arm channel on freenode. If you believe it's a bug, file a bug against ubuntu-nexus7 in Launchpad.

Ehm, do i miss something or is this ubuntu only installation?
Edit: i mean, not dual boot, but only ubuntu

Do I need a mouse and a keyboard to use Ubuntu? Or I can also without them?

it has a built in touch keyboard/mouse, so you can do either way

you can use a touch screen for it, mouse and keyboard is compatible

what do you mean ubuntu only install?
sorry if you mis understood, but i posted the guide there but i am also curious if theres a dual boot avaliable.

is bluetooth not usable in the in ubuntu while installed?
And I saw this install method over at androidcentral.com and I dont recall it being dualboot. It did a complete install of ubuntu only and erased android from the device

As of right now, dual-booting is not an option, however, this build did just come out today, and in the coming weeks, we'll likely have many updates and options, so i'd hang tight. Needless to say, it's a great experience

yess dual boot will be awesome.

Download and follow the instructions in the complete Linux installation guide. (Its an app in the play store) It works pretty well and you can use Ubuntu, Debian and a few others without wiping your system. I prefer the Ubuntu lite version. Something else to try out

Why did you title the thread as "Dual Boot Ubuntu" then?? Confused as well.

Change your thread title,its misleading.

yes my question was about dual booting, sorry if theres any confusion caused.

Folks, it's not that hard of a question when you actually read what the poster states. CURRENTLY, THERE IS AN INSTALLER THAT INSTALL UBUNTU TO THE NEXUS 7, BUT DOING THIS WILL CAUSE THE DEVICE TO BE FULLY WIPED FIRST REMOVING ANDROID. HE IS WONDERING IF THERE COULD BE [OR IS] AN INSTALLER THAT INSTALLS UBUNTU ALONGSIDE ANDROID TO BE ABLE TO BOOT THE DEVICE TO EITHER OS AS THE USER WISHES [ ALSO ASKING IF DUAL BOOTING BETWEEN THE 2 IS EVEN POSSIBLE.SO HE KNOWS IF IT IS WORTH HIS TIME TO INVEST IN MAYBE FIGURING IT OUT ON HIS OWN]. I am going to assume some form of dual booting would be possible as Linux bootloaders are generally very capable of booting OSes that use environments totally different from itself.
I am wondering the same thing as I am a very good technical user who can deal with a lot of issues, but have never gotten deep in to the programming side of things. I am shocked that for such an alpha build [really flaky Bluetooth, [Wi-Fi is solid] Unity crashes quite often and nVidia has had sucky Linux driver support for years now [wish they would take Linux more seriously but hey at least they have drivers]]. All leads to a painful experience for most [especially if you are not a nerd or techie and not used to dealing with very new alpha Linux type issues, if you don't mind it it does work].
Why wouldn't they have set it up as a dual boot to begin with? That way if you know something you need to get done can be done in Android and not in Ubuntu then you could just restart and choose the different OS. Not to mention if this is for modders and enthusiasts to test bed things on the tablet then they are going to most likely be some Android developers to start who would love to say use Eclipse to develop Android code for whatever and then oh no restart in to Android to I dunno test their work.
All that to say PLEASE SOMEONE WITH THE KNOW HOW let's figure out a way to fully dual boot a NATIVE Linux [not that install a loop file system and have it use VNC server to view the session junk you see on the Play Market, it's quaint and all, but not nearly as nice as a full Linux with full access to the hardware [I use it too, much love to backtrack] but am dying to dual boot an Android/More full [ I REALLY want Backtrack 5+ but Ubuntu would be worth keeping around until Backtrack gets around to working out their builds to be dual boot on some Android based systems] Linux as needed.

The approach that the Boot Manager app uses would probably work. They modify the /boot partition to point to a different device for /data than normal. Then you can switch between ROMs by flashing a different /boot partition. They automatically bundle the /boot partition into an update.zip and store them next to the image file on you SD card.

thanks for clearing it out RealPariah! by the way your username link to the band pariah orr? Cheers.

I would like to try this but what's the best/easiest way to back up my system? (I.e. app and game save data as well as for directory bind and folder structures). I tried clockworks backup process before, but I either did it wrong or it doesn't cover everything.
Can I just copy paste everything from my root folder?

you might want to try and use titanuium backup and copy out the entire "titanium backup" folder onto your computer, so when you revert back to android you should be able to copy it back in and restore from titanium backup. hope it works.
