[Q]How to extract CPUID from bricked A500 - Acer Iconia A500

My partner has a bricked A500. It will NOT boot so any utilities utilising adb/dmesg fail. I can boot into fastboot mode (v0.03.11-ICS) but fastboot returns USB write errors stating invalid partition format "." So, I assume I have to use nvFlash to re-write the partition table but this still requires the SBK that I can not generate as I do not know what my CPUID is.
I have read so many threads all offering tweaked variations of the same process but I haven't found as yet a definitive how-to on re-creating your CPUID/SBK on a bricked device as they all assume you either know your CPUID or the tablet stills boots so you can retrieve it easily.
Does anyone have any links to resources to assist? I currently can boot into fastboot and APXmode. Attempts to factory reset seem to kick off OK but then fail with errors erasing data/cache etc... I have both windows/linux and the tablet is recognized in APX/fastboot mode on both OS's.
Thanks

1- download the attached file
2- go to linux
3- install GCC , lsUSB , Libusb-1.0.x , libusb-1.0-dev (from “Ubuntu software center” )
4- drag and drop the APX.c file in your desktop
5- connect your tablet to the computer (through mini USB) and put it in APX mode
6- Now on computer fire up “Terminal” and type this code
Code:
cd Desktop
sudo su
gcc apx.c -o apx -lusb-1.0
7- a new file should appear in your desktop
8- keep typing :
Code:
./apx
it will return to you the UID (AKA: CPUID)
DONE

Error: Failed to open device

Many thanks for the walkthrough.. n sorry for being such a noob!
My A500 is bricked, and not flashing through update.zip method.. dint have my cpuid so decided to follow your guide.. installed Ubuntu on my windows pc, installed all the additional packages you just mentioned, but after the last command of ./apx it returns with Error: Failed to open device !!!
Now What? can there be ANY way or ANYTHING i can do to get over with this LLAAAST step? pretty pretty please!?
Thanks in Advance!

Put your device in APX mode, manually. Then get it.
Sometimes, if you leave it in what you think is APX mode, for a certain amount of time, you may not be able to connect to it. So do it fresh.

Hmm thanks.. Meanwhile I did the code tweak as digested here: http://forum.xda-developers.com/showthread.php?t=2331151
And got my cpuid as 0x00000042dfd497
Hope this is what I needed? Although the characters are 14 if I exclude 0x?
Thanks again mate!

Well, if I'm not mistaken, it should be 16. You can try it either way.

SUCCESS!!
I finally managed to unbrick my tab, SPECIAL thanks to @Moscow Desire, @eppeP, @civato and @srbeen.. here's what i did, thought it might help someone else like me!
Booted my PC in Ubuntu, to extract the CPUID, as i didnt have it saved. for that i used instructions from this post: http://forum.xda-developers.com/showthread.php?t=1751978
Nevertheless, i couldnt completely follow it till unbricking, as somehow things didnt quite work out as expected. Expecially, the UID i recovered was as i quoted above, filled with many zeroes.. i got the correct one after tweaking with apx.c file as advised here: http://forum.xda-developers.com/showthread.php?t=2331151 because i later realized i was using a 32-bit system.
After recovering my UID, downloaded the "V8-UNL-ICS-HC-bootloader-MULTI-cwm.zip" thing, given here: http://forum.xda-developers.com/showthread.php?t=1622425 .. its a simplified form of nvflash, and is easier to operate for less techno ppl like me. Booted to windows, downloaded and extracted it, and edited the v8.bat file to remove any cls commands and see what this thing does. Then, opened the command prompt with Administrative rights, and run the V8.bat file... Once my tab was unbricked, i could easily flash any update.zip package i wanted!!
Sounds easy! but believe me, its easier said than done! took me over a week to complete the whole process as i tried almost EVERYTHING as anyone suggested in ANY post to unbrick my tab! but nevertheless, got the result finally and thats what matters!
Guys, the devs at xda, You ROCK!! :good::good:

[STICKY][ROM] nvflash FULL restore, using bekit's original image (Instructions)

MANY THANKS TO REV FOR RE-WRITING THIS FOR ME!
(Post was updated on 3/23/2011)
=======================================
This post is to provide a template for using NVFlash to restore/recover your G-Tablet after suffering some kind of malfunction. Specifically, this document tries to provide ALL the information you need to use the NVFlash tool to recover the bekit 1105 software version, which has been found to be safe as a starting point for rebuilding your tablet after having a problem. This post does not include other methods of setting up NVFlash (such as installing the SDK, etc.) because this method is proven and can be easily supported.
I use Ubuntu Linux and know that the Linux instructions below are correct. Others have written Windows instructions and those too have been checked carefully and have been used before successfully.
A WARNING IN ADVANCE: NVFlash makes changes to the partition structure of your device. You should tread carefully and understand the risks. (MOD EDIT Note: It also has been noted a bunch of times that even NVFlashing your G-Tablet will not completely overwrite everything on it.)
The NVFlash setup process begins with a visit to:
http://db.tt/Wm25t7U
(Note: Sometime this DropBox is cranky. If you have trouble with it, check back later.)
Linux users: You want to get "nvflash_linux_2010110500.tar.gz" and "nvflash_gtablet_2010110500.zip "
Windows users: You want to get "nvflash_windows_20100500.zip" and ""nvflash_gtablet_2010110500.zip"
Note: The above "nvflash_gtablet_2010110500" is commonly referred to as bekit version 1105 in many posts relating to nvflashing (especially my posts).
-------------------------------------------
Installation
First, create a folder named "NVFlash" on your PC to put the needed files into and to work from. (Note: You can call it something else if you want to; we're just using "NVFlash" to keep all of us on the same page.)
Next, extract the files you downloaded from the DropBox above into the "NVFlash" directory. The files with linux and windows in the middle of then are the files for setting up NVFlash. (The are taken from the SDK and do not install the whole SDK -- just a simple, operable NVFlash for us to use here.) The files with gTablet in the middle contains the .img files with the software to go on your G-Tablet.
Third, for Windows users, you'll need to have an APX-specific USB driver for the next steps. (The Windows package bekit supplied has an .inf file in it, but the actual drivers are not there). For Linux users, you don't need an extra driver.
One source for the Windows drivers is at
http://www.myadventvega.co.uk/
Find the "Downloads" tab in the middle of the page and click on "USB System Driver" to get the files. Extract them and go down two levels to the "USB" folder -- and move that into your "NVFlash" directory. The USB folder has the .inf file for installation in it along with two other directories with drivers for the various operating systems. (Note: These drivers, which are the same as the drivers in the SDK, are proven to work with Win 7 64-bit and have the setup include to load into other versions of Windows.) Follow this narrative for actual installation of the drivers.
CHECKPOINT: At this point, you should have the nvflash files, .img files, and USB directory (and files) in you "NVFlash" directory and are ready to begin the recovery process.
Now, you will need to boot into G-Tablet APX mode: hold down the power and volume - button simultaneousl until your G-Tab comes up and the goes back to a black screen. The black screen means it is in APX mode and it is waiting to display the flashing process. In Linux, type "lsusb" in a terminal and you should see this "0955:7820 NVidia Corp.". 7820 means the device is in APX mode.
Connect your G-Tablet to your PC using your miniUSB to USB cable that came with your tablet.
Linux users: At this point, open up a command window to the folder you created, and run this script:
./nvflash_gtablet.sh
This will wipe the device back to bekit's original TnT stock image, except for user data which is retained. Should take about a minute to run and the device will reboot itself automatically. If the script does not work, make sure that the shell script and nvflash binary are set as executables.
Windows users: When you connect to the PC, the PC immediately tries to load a driver -- but since it doesn't know where the USB driver files are it will fail. Click through Start/Control Panel/Device Manager and find "APX" listed in the devices with a yellow "!" (exclamation point) on the icon. Select the APX item and find the "Update Driver" button and click it. When it asks where to search, choose the local computer manual selection choice and tell it to Browse.
Point the Browse (and the USB install) at the "USB" directory under the "NVFlash" folder. When pointed at the "USB" directory, the driver installed and I was ready to nvflash. If you go back to Device Manager after the Windows install has completed, it will show the nVidia USB drivers near the top of the USB device list.
Again, for Windows: Run this script which is in the "NVFlash" folder:
nvflash_gtablet.bat
This will wipe the device back to bekit's original TnT stock image except for user data, which is retained. Should take about a minute to run and the device will reboot itself automatically all the way to the main screen.
POST NVFlash:
When your G-Tablet has booted back to the main screen, you will have to check and make sure everything is set up. Particularly, get the wifi on and connected to the Internet. Almost immediately, you should get a notice about an OTA (over the air) update. This is the OTA Update to software version 3588. If it does, go ahead and have it do the update. From there, you can begin using your "stock 3588" G-Tablet.
If you don't get an automatic OTA notification, you can go the to manual "Update" icon on your tablet and have it check for updates -- and hopefully it will find OTA 3588.
Or, if neither of the above happen, you can download 3588 at the following link and install it manually:
http://tapntap.http.internapcdn.net/tapntap/viewsonic/update-smb_a1002-3588-user.zip
Note: Following is a STICKY from General Forum on the stock recovery process:
http://forum.xda-developers.com/showthread.php?t=892090
NOTICE: There are many threads out there with tell how to do this process. Others tell individuals' problem solving experiences. A few of them may not be right! The above process is not the only way to do this -- but it is fairly straightforward and it is proven. It is recommended for anyone who does not have experience with nvflashing.

An additional suggestion if you also want to tack on bekit's clockworkmod recovery versus standard recovery: http://forum.xda-developers.com/show...3&postcount=17
Hope this helps!
03/2011 update -- I've been told that this tool has been useful to erase ALL partitions, including user data. I believe you need to re-flash with the bekit 1105 above, AFTER you use this: http://forum.xda-developers.com/showthread.php?t=974422
04/22/2011 update -- I've built out both 1.1-3588-based and 1.2-4349-based versions that have effectively replaced bekit's 1105 image ("nvflash_gtablet_2010110500.zip"), at least on my own device - I'm also addding a clockworkmod recovery option. It is being hosted in the same location as my 1.2-based mods - I will be making updates there, from this point on (as I might update them from time to time).
(you'd still need bekit's Windows or Linux tools, keep in mind) I've been able to bring back my device back from a soft-brick several times, so I feel they are usable.
05/09/2011 update -- A reminder that these images are not being updated, here. I have a newer nvflash post over in the same site where I have my 1.2-based mods. The 1105 bekit image mentioned here is still relevant for 1.1-based ROM users, or you can use my 3588 ot 4349 solution at the other site.
05/10/2011 update -- I have PM'd the moderator to either unsticky this post and / or assign it to someone else, as I do not plan on updating it, here. I believe that there is a 3588 image in the TegraTab IRC that someone created, for example.
Looks good Roebeet. I wrote a little how to a while back on tegratab. I know you are aware but for the benefit of others I wanted to add the following.
One little thing is sometimes when you are done you will get a boot loop. I think it only may happen once as I never saw it again. The fix is to go into Clockwork and partition the internal sd card again. The old settings said 512 for memory, and 256 swap. Bekit updated Clockwork and now you can format all the way to 4gb if you like, and swap should be 0 as it is not used.
Edit: New wisdom says not to partition the internal sdcard to anything but 2048. Folks have had issues with memory errors in the market with anything bigger. 0 for a swap is also the recommendation as Android apparently does not make use of the swap.

I need help. I finally got Windows 7 to recognize the device in APX mode but how do I flash from this point. It only shows up in my Device list with all the subfolders in it.
What is this for? Restoring to factory Rom?
Thanks,
Scott

Yes, you can use it for exactly that. I believe bekit added Launcher Pro and superuser, but other than that it's a way to completely wipe the device. Moreso than a standard recovery would do.
The pre-req link doesnt work. Can you update the link?

Roebeet sorry but I just noticed for noobs that the linux command needs to be
. nvflash_gtablet.sh
Also if you unzip those files into a premade directory such as "gtablet" when you unzip them each have their own directories and if you ls you can see that the bash script isn't executable from there. So you need to copy either the gtablet files into the platform folders or copy all the files inside both into your "gtablet" folder. Then you can run the ". nvflash_gtablet.sh" command and voila. Sorry I am on Ubuntu and don't know if it is different, but that is the way I run them.
No worries - all replies are welcome! the more info we have, the better.
This should be stickied. Nvflash has saved my gtab many times and I think its the reason why my gtab doesn't really encounter too many Force closes. Its the perfect method to ensure your gtab is clean.
I tried this tonight to try to get my gTablet back to stock so that I could show people how to install CWM on a video but I could get neither of my Windows 7 64-bit computers to recognize the APX .inf that was included in the pack.
I have a linux machine around here somewhere I may have to use...

My limited experience with 64-bit Win7 -- the drivers have to be signed, or else they won't work. There's a way to disable that on boot, but you can't permanently disable it. I'm wondering if the APX USB driver is signed?
Open a command prompt as an admin and type
bcdedit -set loadoptions DISABLE_INTEGRITY_CHECKS
bcdedit -set TESTSIGNING ON
This is the only way.. dont worry if the test watermark shows up.. it wont affect anything.
Also... They have a x64 driver - read this

Hi there,
I exchanged for a new Gtab yesterday from sears (as it had some power issues).
Today, I tried TnT 2.2 on my rooted tab (Z4 for rooting). Also have ClockworkMod .8.
I partitioned my internal SDCard. But after vanilla restore, I could find my tab space reduced to 4 gigs. What should I do to restore to full 16 gigs(14+ gigs actually).
============================================================================================================================
2. I followed your instrction and partitioned again in clockworkMod and did 4 gigs and 0 in the second one. Now it shows 11 gigs for data and 4 gigs for system.
Now I inserted an external micro SD card (16 gigs) but my storage is not seeing it. What should i do? Ignore my first part please.
Your gonna have problems later if you don't repartition to 2048 and 0

You only have 16gb to start. Partitioning you internal to 4gb uses part of that. I would go back and only use 2gb, and 0 for swap. There are things, like the new market that break with anything but 2gb.
If you mean the settings menu is not showing your external sd card that's normal. Look in a file explorer program in the / directory. Look for SDcard2. That is your external. Same deal, look for usbdisk if you plug in a usb drive.
Roebeet
also this could be helpful to Ubuntu/linux users.
in the same directory where your flash script is there is a file that is called "gtablet.cfg" if you download the clockwork.img recovery and put it in this directory you can open up the "gtablet.cfg" with a text editor
scroll down to where you see "filename=part9.img" and replace "part9" with "clockwork" and it should now read "filename=clockwork.img" this will flash clockwork and save you a step. To change it back so you flash complete stock just edit the file again and reverse it.

You don't even have to do that - you can just rename part9.img to something else, and clockworkmod.img to "part9.img". That's actually what I do.

Yeah I thought about that, but figured some people might get confused and forget which one was which. Either way works as well just as long as you keep both files. You should edit your original post and add that in as an option to do at the end. It will keep some from having to look through and creating a new post cause they can't find it, and keep our forums clean.
This should definitely be stickied. Mods please?
P.S. I cannot believe how awesome this forum is(Viewsonic G Tablet). I have gone to other forums and the other devs and users are not as friendly and awesome as the ones we have here. Almost brings a tear to my eye. Great job Roebeet, this should help us noobs out a lot. LOL!

Locked bootrom?

My problem:
I’m trying to root my device but after running download.bat(from Nvflash), the “NVIDIA USB Boot-recovery driver for Mobile devices” disappears from the device manager in windows and I get this message CMD:
Nvflash started
rcm version 0X4
Command send failed (usb write failed).
Replugging the usb cable doesn’t work, TF need reboot 10sec power button.
Info:
Since Saturday, the owner of a 16Gb model with dock.
Serial starts with B70KAS…..
Firmware: HMJ37.WW_epad-8.4.4.11-20110711
PC: Windows 7 x64 and Windows 7 x86.
Is it possible than I have locked bootrom?
Please help me after more than 24 hours trying to root my TF I don’t know what to do now

Doesn't make any difference.
Please describe exactly what you are doing, and spare no details. It's hard to help decide if you're doing anything wrong when you are just saying "I've done everything" "doesn't matter", etc.
List exactly what steps you're taking
1-how you're hooking up to your machine, directly, or through the dock?
2-are you putting it in apx mode correctly? can you use adb to confirm?
3-what files you have in the nv_flash directory. Names and where you got them from.

I make direct connection with TF no dock or usb hub. Buy the way i have the same problem on other pc with ubuntu running.
I have recorded the whole process, use HD and full screen for better resolution.

I'm no windows expert, but is there a difference between double-clicking on download.bat, and running download.bat from the command prompt?
Also, you should check the md5 hash on the downloaded files to make sure they aren't corrupted. I had to download prime's files a few times because of this.
I've seen two suggestions in the other thread
1-run the nvflash commands yourself, i.e. not from the download.bat
2-is there a ww version of nvflash? Maybe you need to run that?
Did you try to run the .bat file directly from win explorer? I seem to recall that i did it that way. I used the method from this thread and it worked perfectly:

No difference between doubt clicking and running the bat in command prompt, with the exception that if there's no PAUSE in the batch file it'll auto close if it finishes execution. It not even making proper connection means it has nothing to do with files being corrupt.
I suffer from the same problem i think, advice has been given here: http://forum.xda-developers.com/showthread.php?t=1193667&page=2
but i haven't found a solution yet.
is there anyone that can confirm you get a 0x4 error on an invalid boot image? would think the error would be different. I've tried with 1.6r2 and 1.4, on 32 bit, 64 windows and a 64 bit ubuntu. All give the exact same error.
i've tried the tf rootkit and the nvflash from the unbricking thread, both give same results

OUTDATED[Guide] Setting up/using adb/fastboot-unlock, flash custom recovery & root
Below is a great guide to rooting, from several sources, (mostly taken from pingvinen's "An Idiot's Guide to Flashing the Xoom" and a guide by publicanimal. and I hope it helps. You can find the links to all of the files referenced below in the Xoom Heaven thread (thanks StrifeSoldierVII!)[/I]
(New thread in General Section by Jack207407 will have all the updated links for flashing
http://forum.xda-developers.com/showthread.php?t=1443110
One Stop For ROM's, MOD's, and Root Wifi-Only and 3G/4G Models)
"What you need to do can be encompassed in these following short steps (will be detailed later on) in the following order. Each step is required before you can proceed to the next one. However, make sure that you are very very careful and don't try to take any shortcuts. That may soft-brick your device, and you may have a difficult time to explain that to your wife ... You have been warned.
HERE'S THE USUAL DISCLAIMER--I AM NOT RESPONSIBLE FOR ANY HARM THAT MAY COME TO YOUR DEVICE IF YOU FOLLOW ANY PART OF THIS GUIDE--ANY RISK IS ON THE USER!
I strongly recommend you to read the entire guide before trying. In fact, read it twice to ensure that you have understood everything. If there is weird stuff that you don't understand, don't hesitate to ask. The reason for me writing this down is that I like to document what I have learned. This is to me an excellent way to ensure that I will remember what I just did. Another reason was that I could not find a single thread that encompassed all steps required. There are many different threads, but no one (that I could find) that really guides you from start to goal. So enjoy and good luck!
I would like to thank LandMaster and cam30era for helping out with advice during my initial trail-and-error session. I soft-bricked my device once and had big problems to get by point 4.3 (avoid overwriting of CWM), but with their encouragement I finally succeeded.
Just a note before we begin: the different Xoom. Models that are able to use this guide are the following:
MZ600 - stingray_cdma - Motorola US 3g Xoom (technically this device is stingray as well, but I will be using stingray_cdma as the two devices have incompatible software)
MZ601 - utms_everest - Motorola EU 3g Xoom
MZ602 - stingray - Motorola US 4g Xoom
MZ604 - wingray - Motorola Wifi Xoom
(thanks solarnz!)
___________
Overview of the 6 required steps
1. Install Motorola USB drivers for your computers (for USB connectivity) 2. Install Java SDK and Android SDK tools (for adb and fastboot commands) 3. Unlock the device for flashing (allowing replacement of recovery and boot images) 4. Install a modified recovery image (ClockWorkMod recovery for Android) 5. Root the device (Allow r/w access to the device filesystem) 6. Flash a kernel that supports overclocking etc.
Steps 1, 2, 4, 5 and 6 require that you download install, image and zip files needed for the flashing.
All this was performed on a Windows PC. Windows 7, Mac and Linux users will probably have to do some steps differently.
1.0 Install the latest Motorola USB drivers
The installation file can be found at: http://developer.motorola.com/docstools/USB_Drivers/
1.1 Install the drivers and ensure that your Xoom is recognized by the computer
2.0 Installation of development software
Android SDK and Java SDK need to be installed. You can find the installation kits here.
http://developer.android.com/sdk/index.html In case you can't find fastboot.exe, look for it here (thanks to jerrycycle): http://forum.xda-developers.com/showpost.php?p=19546334&postcount=5
Update: you could also just install the adb fastboot pack here:http://www.android.net/forum/downloads.php?do=file&id=67
http://www.oracle.com/technetwork/java/javase/downloads/index.html
2.1 Install them as any other software, making an Android SDK folder on C/.
2.2 Make sure that all the files you need are in the Platform Tools folder (fastboot, recovery image file and so on). Copy any files in the Tools folder to the Platform Tools folder if necessary. Note: If the Android SDK complains that the Java Dev Kit can't be found, just press Back and then Next again. Wierd, but that seems to do the trick ... go figure.
(Warning: Never put any zip files in your Platform Tools folder. Flashing zip files through fastboot will cause very serious problems. Zip files must be flashed from the external micro SD card through CWM recovery on the Xoom...we'll get to that later.)
2.3 Test that ADB and FASTBOOT works. You should open a command window by right clicking in your Platform Tools folder where all of your files are, plug in your Xoom to your computer with your Motorola cable (it may not work with a generic cable) and write 'adb devices'. Your Xoom should now be listed. Did your device not show up? Make sure that you have USB debugging enabled in Settings/Applications/Development on your Xoom.
Optional: Those that want to be able to access adb from any where on their computer, here's a tip from scsa20: "For windows, if you go into System Properties and choose Advanced, then Environment Variables..., you'll be able to edit the Path variable under System variables, just add the path to where adb and fastboot is located (separated with a semi-colon ().
Here's what my Path variable looks like:
C:\Program Files\Common Files\Microsoft Shared\Windows Live;C:\Program Files (x86)\Common Files\Microsoft Shared\Windows Live;C:\Program Files (x86)\NVIDIA Corporation\PhysX\Common;%SystemRoot%\system32;%Sy stemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\ System32\WindowsPowerShell\v1.0\;C:\Program Files (x86)\Windows Live\Shared;c:\Program Files (x86)\Microsoft SQL Server\100\Tools\Binn\;c:\Program Files\Microsoft SQL Server\100\Tools\Binn\;c:\Program Files\Microsoft SQL Server\100\DTS\Binn\;C:\android-sdk-windows\tools;C:\android-sdk-windows\platform-tools;C:\Program Files (x86)\Common Files\Acronis\SnapAPI\
It's long but do you see the android stuff there at the end?"
Update: xda poster Mandelbrot Benoit suggests an alternate adb setup, here: http://forum.xda-developers.com/showpost.php?p=18072572&postcount=50
If your windows computer doesn't see your Xoom, consider this (Originally Posted by AngryBulleteyeTruth):
When the xoom does not show up on PC it may be the problem of.... windows media player!
Xoom uses drivers of WMP to communicate with PC. If someone does not have the newest WMP drivers it will not show up and you can see xoom device in the devices tab on PC having an exclamation mark.
So the solution is to download and install Windows Media Player 11. It has worked for me.
--------
OK. Now that you are set up, it's Showtime! Take a deep breath...
3. Unlocking the device for flashing
This step will effectively erase the internal storage, including all your apps and settings. Use whatever backup you want to secure important data before you start. (It will also void your warranty, so you still have time to go back.)
3.1 Power up and start the Xoom.
3.2 Ensure that your device is fully recognized by the computer. A good sign is that the 'Portable device' dialog is activated on Windows when your Xoom has booted. The Xoom should also be seen in 'Computer'. If not, go back to step 2 and double check your USB drivers.
3.3 Use the command 'adb reboot bootloader' to go into Flash mode.
3.4 Use the command 'fastboot oem unlock'. This will trigger a dialog on your Xoom. Follow the instructions on the screen to complete the unlocking. I repeat, this *will* do a factory reset and all data will be lost!
3.5 Once unlocked, the Xoom will restart and work as normal. Don't bother to do any setup at this time, just make sure that USB debbuging is checked in settings, and now go on to step 4
4. Install recovery image (CWM) UPDATED 4/19/12
If you haven't done it already, download the recovery image file and save it to your computer in the Platform Tools folder.
(Download the recovery image from this link: http://forum.xda-developers.com/showthread.php?t=1604014 only the img file flashed through fastboot Remember, never try to flash a zip file through fastboot!)
Important: At this time, make sure you have a good (known to be working) microsd card in your sdcard slot in your Xoom. Reboot the Xoom with the sdcard in the slot to make sure it's mounted.
4.1 Boot into flash mode with 'adb reboot bootloader.'
4.2 Install your downloaded recovery image: 'fastboot flash recovery eos-recovery-r6.img' or whatever is the exact name of the recovery img file you are flashing.
4.3 Enter CWM recovery with the procedure below.
4.4 Restart the device with 'fastboot reboot'. Timing is essential here, so be alert when the device restarts, or you will have to redo section 4.
4.5 Once the Motorola logotype is shown, start counting to 3. At 3, press the Volume Down button. This should result in the text 'Android Recovery' in the top left corner. If it does not work (if you see Starting Fastboot Protocol), experiment with the timing (see below).
4.6 When 'Android Recovery' is shown press the Volume Up button. This should invoke the CWM recovery menu. If that works, then congratulations for getting this far!
Here is a potential pitfall. If you are unable to enter CWM *before* the device boots into Honeycomb, then the newly installed recovery image will be overwritten by the system default recovery. Just repeat steps 4.1 through 4.6 if that happens.
UPDATE(12/28/11) Since putting this guide together, Motorola has issued a number of Over-the-Air (OTA) updates that have complicated the process of flashing the Clockawork Mod recovery, so if you have accepted any OTA updates, please read the following, which describes each step (http://forum.xda-developers.com/showthread.php?p=26009191#post26008083) (Thanks to Landorin.)
(If you have root and want to remove these files, remove or rename /system/etc/install-recovery.sh with something like root explorer. You can then flash your custom recovery through fastboot again.)
For those of you that get stuck with some error like 'device not recognized' poster Madjinj gives the following advice:
1) Be sure that you have your adb folder in the root of C drive directly and be sure that you are in adb folder in command prompt program (CMD in Windows machines) i.e by typing "cd c:\XXX" where XXX is the name of adb folder in your machine.
2) Be sure that you type "adb reboot bootloader" in comand prompt to activate adb program. if the problem persists, try typing "fastboot reboot" then after reboot type "adb reboot bootloader" in command prompt program.
3) Use the USB cable that came with your Xoom (some cables are not good in flashing for unknown reason..!!
4) make sure that you activate USB debugging mode.
5.0. Rooting the Xoom
The Universal Xoom Root zip file from solarnz is located here: http://forum.xda-developers.com/showthread.php?t=1242241
5.1 You need to transfer the Universal Xoom Root zip file to a working external micro SD card. You can do this on a computer or cell phone, but the Universal Xoom Root zip file must be located in the root directory of the micro SD card.
5.2 Insert the now prepared SD card in the Xoom.
5.3 Boot into recovery (as described in 4.3). Navigate using the volume buttons and press the power button to select the active option.
5.4 Select 'Install ZIP from sd card.'
5.5 Select 'Choose ZIP.'
5.6 Navigate to the ROOT zip file with the Volume buttons and select it with the Power button. Confirm that you want to install it.
5.7 Everything should indicate success, so back out to the main CWM menu and reboot the device.
5.8 From Android Market, install any app requiring root and start it. If the rooting was successful, then the app should request superuser permission and you should be able to grant it without any problems.
6. Flashing a new rom or kernel...(e.g. Tiamat Moray Rom and/or Odachi Kernel). Look in the Xoom Heaven thread or in the Development section of this form for all of these files.
6.1 This step is identical to 5, but swap out the ROOT zip for the ROM or KERNEL zip. For simplicity, you may want to prepare the micro SD card with both zip files at the same time in step 5.1..."
------------------------
This is still one of the best explanations of how to use adb and fastboot to unlock and root the Xoom and install a custom recovery, etc, and doesn't deserve to buries on back pages of this forum. Hopefully, the step-by-step nature of this guide will help those of you that have limited experience with this kind of tinkering.
Oh, and please feel free to correct any errors or omissions. As I said, it came from several sources and needed to somewhat updated.
Thank you, just bought my xoom yesterday and was confused on the steps to take!
This has made it as clear as possible for me and will follow your instructions to the letter tonight.

Check to make sure that your file download is good, and that you are typing it's name correctly. Better yet, you could rename the file "recovery.img" and that will make it very easy to get it right.
On the sd card?I thought we had to put it into sdk platform tools? I have put it and renamed it onto my sd card but what is the command to flash recovery from sd card?
Also noticed once I have done "adb reboot bootloader" my computer doesn't see the XOOM properly, is in can't see it in my computer but does make a noise when I connect and disconnect is this correct? Debugging is on.

When you're in the bootloader, you won't be able to access the SD Card or anything of that sort and adb won't work, in stead, when you're in the bootloader, you're switching over to fastboot. I'm sure if you type in fastboot devices you'll see your xoom listed.
Thank you for the reply and that's one thing sorted but any idea why its telling me "cannot load recovery"? I have tried renaming it and downloaded the recovery file 4 times incase that was wrong but still no joy :-(
I have done this all before on my phone and never had a problem so I must be missing something but f$*@ed if I know what?
Thanks again for your help though.

Just had a thought. Could it be that the XOOM hasn't actually unlocked, would that cause it to not load? Is there any way to check if its unlocked successfully? Although I did try it twice before?
Sent from my MZ604 using xda premium
Once you got it in the bootloader, you gotta make sure you do fastboot oem unlock, press volume down then up, press volume down again then up again, and let it format and reboot.
If it's already unlocked, you'd get a message telling you so (generally).
Then when you go to flash the recovery, make sure that the recovery image is in the folder where fastboot is and type in fastboot flash recovery recovery.img (if I remember the syntax that is, I'm at work and don't feel like scrolling up or going into the root guide to confirm xD ).

If, as you follow this guide, you find any explanations that are not clear or if you think of a step to take or something else that might improve the guide, please post it and we can add it in. It's been almost 6 months since I've unlocked and at least a couple of months since I've had to use adb, so I'm sure I've forgotten some things. Those of you whose experience is fresh can give really good advice. That's how this guide was originally written, by pingvinen, right after he had gone through a grueling rooting process.

We all have learned some things from trial & error (eg.the sk cannot detect java dev kit)
i could only flash recovery after renaming it to recovery(do not forget to add.img in cmd while flashing).also the official motorola name recovery as same.
after downloading sdk and updating to platform tools i have kept a zip in safe location so that i do not need to download again platform tools if i install sdk fresh
initially knowledge was scattered now it is at one place.
right now testing steady hawkin's kernel and new recovery
btw good signature pic.
Ok so another night has gone and still can't get recovery on!! Tried re unlocking the XOOM and every time it comes up with "cannot load recovery.img" I tried installing everything on my laptop and went right from the start and getting exactly the same thing!
Starting to think im never gonna get this sorted now :-( just feels like the XOOM isn't unlocking? Every time I go through the unlocking process it never states that its already unlocked? Is there any way I can check that it is unlocked?
Please help im losing the will to live now lol

I would say to send it to me and I can take a wack at it but I don't think you want to wait that long to simply root it.

Not getting any error message it just says "cannot load recovery.img"
I have tried with and without the .img and always the same?
Tried going through the whole process again on my laptop incase I had missed something but exactly the same.
When I unlock it I follow the onscreen instructions and at the end it says its complete before it reboots. Then I turn on usb debugging again and reboot bootloader all ok but won't let me load the new recovery?
Normally I would just say it wasn't meant to be and leave as it is but I wont be beaten on this so I'm purposely not installing anything on it till its done. Any ideas apart from bringing it round yours lol ;-)

[HOWTO] Backup and Restore the System Software

The recently posted rooting method for the KFHD has been great for owners to get started on modifying the device to suit their own tastes. However, I've been a little concerned about everybody jumping in without a safety net in place. There are numerous ways that this device can get bricked. Not to put all of you into a panic, but just getting an eventual OTA update from Amazon might put some of these rooted KFHDs in jeopardy. With no custom recovery on the horizon, I think it's important to have some backup/restore plan to get these devices booting again.
Overview
This backup plan involves making raw data clones of all critical storage partitions required to boot the device. These backup archives can then be stored somewhere off the device. In case of some critical failure that prevents the device from booting normally, these archives can be used to get the device booting normally again. The restore procedure requires the use of fastboot to write the backup archives back to their proper partitions. The use of fastboot requires a working bootloader, so the device will need to boot to the bootloader's bootlogo at a minimum. If the device has a broken bootloader, this guide will not be helpful. There's currently no working procedure for repairing a broken bootloader on the 2nd generation Kindle Fire devices.
To be clear, this guide is not a backup/restore plan for your data. This is strictly for backing up the system software while in a bootable state and recovering it if some modification bricks the device. This procedure has been tested on a KFHD with system software version 7.1.1. Although I have not tested it, I'm nearly certain it will work just fine on version 7.1.5. If the KF2 has the same partition layout as the KFHD, there's no reason why it shouldn't work for that device as well. Check the post on KFHD partitions for details.
Warning: Everything below is inherently dangerous and can potentially brick your device if they are not executed properly. I have tested various aspects to the best of my ability, but you assume all responsibility for performing any of these steps.
Backup
Attached is a small shell script written to do the following…
Make a "kindlebackups" directory in /sdcard (if necessary) and make it user read/writeable.
Create gzipped backup archives of partitions 1 through 11. This includes all partitions except /cache and /data.
Make all archive files user read/writeable.
The entire backup (stock) takes up approximately 550 MB, so be sure to have at least that much available in /sdcard. Root privileges are required for the script to run properly. The best time to use this script is after step two of the published rooting procedure. That's after the second reboot of the process when the device boots up in emulation mode and allows root access for the first time. At this point, the system partition is completely stock and has not been exposed to any modifications. Even if you are past this point, the backups will still be useful for any bootable state that allows root privileges.
Download the script, unzip and place it into your current working directory where you still have access to adb, then run the following adb commands to copy the script to the Kindle Fire and prepare it to be executed...
Code:
adb push backup.sh /data/local/backup.sh
adb shell chmod 777 /data/local/backup.sh
If the device is in the process of being rooted and it has just finished rebooting for the second time...
Code:
adb shell /data/local/backup.sh
If the device has already been rooted and the su binary is available on the system...
Code:
adb shell su -c "/data/local/backup.sh"
The entire process should take approximately 5 minutes. Once the script has completed the backup, access the Kindle Fire's storage area from your computer, then copy the contents of the "kindlebackups" folder to it. The "kindlebackups" folder may be deleted after transferring to your computer.
Restore
To begin the restore procedure, the device must be put into fastboot mode. My factory cable did the job for me, so I have not explored the possibility of changing bootmodes. I developed this guide on a borrowed KFHD and I do not intend to risk the device more than necessary. Unless someone comes forward with a procedure to change bootmodes into and out of fastboot mode, I'm going to say that a factory cable is required for the time being. Besides, based on my experience with the original Kindle Fire, a broken system almost always means there is no way to change the bootmode through it. Since this procedure will very likely be used on a device that cannot boot completely or otherwise has a bad system, a factory cable will probably be the only way into fastboot mode. If you plan to root or modify your system software, invest in a factory cable.
Use the factory cable (with the device turned off, plug into the device, then the computer) to get to fastboot mode. If successful, a "fastboot" logo will take the place of the original "kindle fire" logo.
Decompress the gzipped archive to be flashed… Linux users have gunzip, Mac OS X users also have gunzip and a built-in GUI utility, and Windows users can use 7-zip. The archive must be decompressed before flashing. Skipping this step will brick your device.
Flash the image file(s) back to the device. In most cases, the device will just have to get a working system partition flashed back to it, but the others are available if they are needed. To flash the system partition...
Code:
fastboot -i 0x1949 flash system system.img
- Optionally erase the cache and/or userdata partitions if the contents of either interfere with the operation of the system software. The system will rebuild them on reboot…
Code:
fastboot -i 0x1949 erase cache
fastboot -i 0x1949 erase userdata
Once the process is complete, long-press the power button (~20 seconds) until it powers down, unplug the factory cable, and power the device back up.
Good luck.
Thanks kinfauns. I appreciate everything you did for the original kindle fire. This should help a lot of people.

When i boot my kindle fire hd to fastboot (by factory cable) and connect it to pc, pc can't recognize kindle, it don't have driver for it.
Could anybody post his clean backup here? Screwed my kindle, want go back to stock. Backup is only way.
Copying kindlebackup folder
Thanks for the script - the backup procedure was smooth -
I couldnt find the kindlebackups folder while browsing through my PC and for others like me who wonder how to take these out of your KFHD, here is a simple way - I used a program called Wondershare MObilego (Manage SDcard option under more tools) Backing up was a cakewalk.
I have no affiliation to this tool maker - Just sharing a way that helped a n00b like me. (First rooting experience)
Thanks for the efforts!
BTW, will a backup from a clean device work for other devices instead of the same one which the backup was created from? Just wondering if people who have already fiddled around their root devices can get a fresh start.

I don't know if anybody has packaged the device drivers set up for this device. If nothing else, you can get the device driver installer in the "Kindle Fire Utility" for the original KF and use that. You just have to change the PID from 0006 to 0007 before installing it and should work. Refer to this post if you still have problems...
http://forum.xda-developers.com/showpost.php?p=23747671&postcount=2
for device driver information. Again, written for the original KF, but the process for installing device drivers is the same. Only the PID is slightly different and that should get edited in the INF before installation.

Glad to hear it worked out for you. I am not familiar with that program, but the KFHD should connect automatically to a Windows device as external storage... does it not?

I have not tested this and don't have a way to do so. I have some concerns about it, but I'm sure someone desperate enough will jump in and try it out. I know it's too late for some, but my suggestion is for everybody to make a backup if you can and not rely on someone else to give you archives after the fact. It's better to have your own backups.

Then you're first going to have problems getting root privileges. You need to get adb working before you attempt any part of rooting or backing up with this procedure.

This is the correct "product" reported by the KFHD. This and the product ID (0007) are the only differences between the KFHD and the original when it comes to installing the device drivers on Windows.

/data/media and /sdcard are essentially the same thing (see the second post in this thread for an explanation of why this is the case). You should have seen kindlebackups in that directory.

You can put the the images wherever you want, but you'll need to specify the path to the file. For example, if you are using Windows and put the kindlebackups directory on C:, you just need to modify the command to...
Code:
fastboot -i 0x1949 flash system C:\kindlebackups\system.img
Thank you for posting how to do this. It opens a lot of doors with at least a little security.
I made a backup earlier without a problem, then went ahead and made myself a factory cable(easy to do and worked great- old asus usb cable, 1k resistor, soldering iron, shrink tape and voila!). I feel much better about doing any mods to this device now knowing I can just flash my backup.

{TUTORIAL} Bodhi Linux on a500

EDIT:
Now you can follow the same process into rogro82's kernel, thanks to Forzaferrarileo. Note that you can just flash the kernel, if you already put it to work with sp3dev's kernel. There's no need to repeat all process.
I've, also, changed some structures for better visualization.
This tutorial is using the sp3dev's precompiled kernel from here or rogro82's precompiled kernel from here. If you want to use rogro82's from scratch or from internal storage, please look, also, some instructions at here. Please note that you will have to build that kernel from sources before proceed. You should be able to use internal storage also, with some changes into this tutorial.
I used a phisical usb keyboard into this tutorial, but bodhi offers an onscreen keyboard into tablet profile. To change into this profile, look at here.
It's partially based into this tutorial. I'll refer to number of steps on that, so please open it. Please read everything before doing anything, and make sure you have no doubts about the process before doing anything. I'm not responsable if it damages your tablet!
First of all, download the Bodhi rootfs from here.
Then, run the first 3 steps from the tutorial above. Please note that if you'll run the rogro82's kernel, the step 2 should be flashing that kernel. For infos about how to flash the second kernel image, please read this thread's first post.
After, extract the Bodhi rootfs into the ext4 partition from your sdcard (I needed to be logged as root or use sudo for doing this step). Make sure to extract directly into the root of the partition (the result of a ls into the root of the partition should be just like running ls /).
Now, you need to donwload the zip file from step 6 from the tutorial. Note that it's not needed to install the packages asked by the step 6, just extract the donwloaded files and copy them into your sdcard's /lib/firmware folder. I just copied the brcm folder into /lib/firmware/brcm and it worked.
Now you are able to boot into the image. Put sdcard into the tablet and then boot from second kernel (hold VOL UP while powering on until it shows bootmenu and select boot into second kernel).
After complete booting, you should have the E17 home screen. For tutorials about this interface, please look into Bodhi website.
For being able to connect into wifi, I needed to open terminology (terminal application into bodhi) and run, as root, the following. Please note that it may not be necessary, but recommended:
- rfkill unblock all
- ifconfig
Now please see what number your wifi got loaded, for me, it was wlan2. I'll call it wlanx, so just change x for the number you got.
- ifconfig wlanx up
To make sure it worked, run "iwlist wlanx scan". It should bring some network details into terminology.
Now open wicd, open preferences and make sure the wifi network is correctly set into wlanx. The default value is wlan0. Then, close preferences and click into reload. Now you should be able to select your network, set up the network preferences and then connect into it.
Now you should be able to install everything you want. As I read, bodhi uses a debian base for armhf version, so you can install anything you can install from debian. Chromium web browser is broken, and firefox is named iceweasel. The default midori web browser works fine, but I personally prefer iceweasel.
Thanks:
sp3dev, rogro82, Kevin Roscom, Forzaferrarileo (if I forgot someone, please tell me, I'll put your name here!)
i'd love to try this! does this run fairly well?:good:
For me it does. I have a class 10 sdcard.

Hey this is my first time installing linux on a tablet. Ive got the partitioned sd card, rootfs, kernel ready to go. just not famaliar with how to flash the kernel. Could you maybe give me an idea of those steps? For a first timer as far as android is concerned, the instructions can be a little vague. Thanks

Please, first, make sure you're using this bootloader for dualboot. Into the thread there are all instructions for flashing the kernel into secboot, on dualboot section, into first post.
Ive been on v8 unlbootloader for awhile. Just never flashed a sec kernel before.

download the fastboot package ( from xda , or search on google ) , next connect the tablet with usb to the pc , reboot the tablet with the bootloader menu and select fastboot ...... the pc will install drivers , when it finish , go in the fastboot folder click SHIFT + right click and select "open command window here " and type this :
fastboot flash secboot <nameofkernel> ex : fastboot flash secboot boot.img

Thanks for the reply! Ive flashed this tablet seven ways to sunday within android, but this is kinda new to me. Recently installed 12.04 on my desktop as my intro to linux without a hiccup. I cant seem to get the tablet to respond to my computer. Have the sd card setup ready to go, terminal only says file does not exist ( in regards to secboot) should sd be in tablet or usb? Ive been at it all day. Should i rename anything? Thanks again.

I Simply cant seem to get the kernel flashed. Once i get past that, i believe its smooth sailing..

Please look if fastboot recognized your tablet. Run fastboot devices. If there's an answer, then your tablet was recognized. It can be missing drivers. From acer site it's possible to find the correct drivers.
ok. so not having the acer drivers seems to be my issue. But, Im trying to do this using my pc running ubuntu, and I'm not sure how to get the acer drivers installed on it. I'm sure there is a trick, but the downloads are for windows. And also the downloads are for honeycomb and ics and im running 4.2.2.
Well I cannot help you installing drivers into ubuntu, I made it into Windows.
on android terminal emulator:
cat /proc/mounts
make sure that data is on /dev/block/mmcblk0p8 not p7
if so then:
dd if=your_second_boot.img of=/dev/block/mmcblk0p7
do it within android, not within linux or initial ramdisk console on you tablet, because linux recognize data as /dev/mmcblk0p7. sorry for bad English.

If you follow strict what Tautvaldas said, it'll be placed in the right place for dualbooting, the same if you use fastboot tool.
Thanks for your help guys. But mixing and matching this and that, i give up. Ive flashed the sh*t out of this tab, but without a unified tutorial, i cant make sense of this. Ive been running linux on my pc and laptop, so this isnt foreign to me, but i need a more straight forward tutorial. Thanks though again. We all have to learn sometime:good:
I ran a dist-upgrade on it and my wifi now seems broken - rfkill can unblock it but ifconfig returns SIOsomething something error, permission denied. Ideas?
