Xoom root and bootloader unlock

I have a uk wifi only XOOM on Honeycomb 3.2. I want to root but do I have to unlock the bootloader first? What is the easiest way to unlock the bootloader and root without adb or fastboot commands. I've looked at 'xoot', 'cornea', and the 'Lord AIO tool'. Do all these methods unlock the bootloader and root? Can anyone confirm that they work for this model? Are there any other easy methods that I've missed?
Also, after I have unlocked the bootloader and rooted can I install cwm recovery from rom manager and then even the team eos v1.0.0 ics rom?
Thanks in advance for your help (I did search, but not much info came up about these methods).

wifi-only-xooms should all be the same.
don't know about the root-methods you mentioned, I used one that includes adb/fastboot-commands (an amazing total of 4 commands were used that day). This is a link to the method I used, it will also work for your xoom.
Why do you want to avoid adb/fastboot-commands?

Thanks for reply. I don't feel confident using adb. And I don'tk now how to use it set it up. Do you know an up to date guide explain how to set it up?
UPDATE: I have now set up adb. Please could you give a little more detail on the method you used. Specifically the unlocking the bootloader part and flashing the recovery via fastboot.
Thanks again.

no, but this is what you'll need to do:
preparations
disable any anti-virus, anti-adware, firewall software you might have on your computer. Best would be to completely uninstall those. If you're using the windows firewall, disable it. You may re-install/activate it after you are done flashing your device.
download and install JDK
google says that the JDK (Java Development Kit) is needed to run the Android SDK. I am not sure if the JRE (Java Runtime Environment) is sufficient, but to play it safe, we're just gonna install the JDK. (JRE is needed to run Java applications, JDK usually to develop Java applications. However, JRE is a part of the JDK and the JDK wont clog up your computer in an excessive way, so you should be safe just using the JDK)
go here and hit the download button beneath JDK.
under "Java SE Development Kit 7u2" (at time of writing, in the future, the release-number might be higher), click the "Accept License Agreement"-option and find the Download that is right for your version of windows. x86 and i586 are names for 32-bit-versions of windows, if you are using a 64-bit version of windows use the file that reads windows-x64 in its name.
install the file, shouldn't be too hard
download and install motorola drivers
If you are using windows, you will need the motorola USB-driver package for adb and fastboot to work.
download the motorola drivers from the motorola website. Open motorola.com, find the xoom's page, find a link saying "support", on the right column of that page you should find a link named "USB-Drivers" or something like that in the "software updates and drivers" section. You should get a page with a link "Download Motorola USB-Driver v5.4.0 with MotoHelper". Do not download the stuff labled "USB-Charging drivers".
At the time of writing this, this link will lead to this file.
once this file has downloaded, just run it and follow the on-screen instructions.
download, install and set up android SDK
The Android SDK (Software Development Kit) is needed to develop applications for android. It also contains the programs adb and fastboot, which we will need. The program SDK Manager, which we will use, is used to download certain parts of the Android SDK.
go to developer.android.com/sdk/ and download the current SDKs zip file. I know, it recommends the installer, but just don't download that.
the zip will contain one folder called "android-sdk-windows", just have your favorite program extract this folder to C:\. I renamed this folder to android-sdk, this is optional but i will assume you did for the following instructions.
you should now have a program C:\android-sdk\SDK Manager.exe. Run it.
A window will open and the program will download a list of currently available packages. After this list has been refreshed, you should find a "Tools"-folder with "Android SDK Tools" and "Android SDK Platform-tools". Check both and hit the button "Install (2) Packages". You won't need anything else unless you really want to develop apps for android.
the installation will take a bit, afterwards, you will find new folders in C:\android-sdk\: tools and platform-tools. Please check, that the platform-tools-folder contains the programs adb.exe and fastboot.exe
(Optional)add tools and platform-tools to your PATH
If you enter a command in windows' command prompt, it will try to locate this command (essentially a program) in the directorys specified in the current directory. If it can't find the program there, it will search in the directories specified in your PATH-Variable.
This step is only needed, if you want to be able to use the adb or fastboot-commands from any directory, like Desktop, your Users folder, etc.
These instructions apply to Windows 7, they will be similar in other Versions of windows.
As I am currently on a german machine, these instructions are a little unspecific. If any user with an english installation of windows 7 could post the exact names for these links&buttons, that would be greatly appreciated.
hit Start, right-click "My Computer" and hit "Properties"
in the left tab, the 5th link from the top should read something like "Advanced System Settings". Hit that link.
a window "System Properties" opens up. Navigate to the 3rd tab "Advanced" and hit the button on the bottom of this Tab "Environment Variables..."
you will see two tables, in the lower list (entitled "System Variables") you should find the variable named "Path": Click on it and hit the Edit-Button below the table.
a small window will pop up with a long text in the lower field (value of the variable). I can't stress this enough: DO NOT DELETE WHATEVER IS WRITTEN IN THERE!!!. Instead: APPEND ";C:\android-sdk\tools\;C:\android-sdk\platform-tools\" without the "". the first ; MUST be there.
hit OK in all three windows
done
This should basically do it. You can now connect your xoom with your computer. Make sure USB-Debugging on the xoom is enabled, that option should be somwhere in Settings -> Development. The first time you connect your xoom with debugging enabled, Windows should give you a message that it is installing some new drivers, but that should work automatically. Same goes for the first time connecting your xoom in bootloader mode.
You can now open a command prompt (Win+R, enter cmd, hit run) and enter "adb devices", it sould read something like
Code:
C:\>adb devices
List of devices attached
012c3456789f1234 device
, that means it worked. From here on, you can follow the instructions in the thread I mentioned in my previous post.

crap, read that too late. But anyways, since I'm already on it:
preparation
we will need some files in order to get your xoom runnin a custom rom. In this section we will download them and put them into their places.
create a folder on your desktop and name it "xoom"
check this thread for downloads. What you will need is Universial xoom root and ClockWorkMod recovery. But again, please check the named thread for updated files. All credits to these files go to their original posters.
at this point, you might just as well just download your new rom, but I won't go into this at this point.
you need an micro-sd-card for your xoom. You cannot use the internal /sdcard partition for this
place the universial xoom root zip-file onto your sdcard. If you already downloaded your new rom, put that onto the sdcard as well, it should be a flashable .zip-file.
place the ClockWorkMod-File in your Desktop\xoom-folder and rename it to recovery.img .
put the sdcard into your xoom, if it isn't in there already
boot the xoom
enable USB-Debugging (Somewhere in Settings -> Development)
connect your xoom using a good and short USB-cable. Let this cable be a trustworthy cable, one that you barely use and that has not been bent, cut or otherwise abused.
right-click on the xoom-folder on your desktop while holding the shift-button on your keyboard and hit "open Command prompt here" (or sth. like that, again, my windows is german)
enter adb devices to make sure adb is working, if your device shows up in the device list, everything is good:
Code:
C:\Users\llama-power\Desktop\xoom>adb devices
List of devices attached
012c3456789f1234 device
unlock your xoom
unlocking your xoom will enable us to flash new files to your xoom. We want to do this. However, unlocking your xoom will void your warranty and DELETE EVERYTHING you've got on your xoom. To unlock this we're gonna reboot the xoom into the bootloader and have it unlock your xoom
to get into the bootloader, you may now just enter adb reboot bootloader
wait a minute. Your xoom should shut down, and reboot into the bootloader. continue if you see the red M and "Starting Fastboot protocol support." on your xooms display
check if fastboot is set up correctly. Enter fastboot devices , this should list your device, just like when you tested adb
enter fastboot oem unlock , this will start the unlocking process. Follow the instructions on your xoom. Bear in mind, this will really delete everything and void your warranty. You Control this thing using the volume up/down-buttons. volume down changes the selection, volume up selects whatever is on your screen. the xoom will ask you if you want to delete/void your warranty/unlock your xoom and if you say yes, it will ask you, if you really really want to do this and then it will unlock itself and delete everything.
I'm not sure if your xoom will reboot on itself or if you will be back to the bootloader screen. in the latter case, just enter fastboot reboot
Your device is now unlocked and has rebooted into a shiny new Desktop.
installing ClockWorkMod
Clockworkmod is a recovery that gives you a lot more options than the stock recovery. For example, it will enable you to create backups, delecte specific partitions and install non-motorola update.zip-files
to install CWM recovery, we will again need to go to the bootloader. So just enable usb debugging in your xooms settings again (remember, you wiped that when you unlocked it) and enter adb reboot bootloader
wait until you are back in the bootloader and "Starting Fastboot protocol support" appears on your screen
to flash the new recovery, just enter fastboot flash recovery recovery.img
remember, for this to work, you still need to be in your desktop\xoom-folder and the recovery-image must be named recovery.img. If your recovery-image is named differently, just modify this command accordingly (fastboot flash recovery blahblub.img)
watch your xoom's screen, once it says that it has successfully flashed the recovery, you need to reset your xoom. It is important, to know how to boot into the recovery right away, so please read this step thoroughly before starting.
To reset the xoom, press and hold vol-up + power for about two seconds. Your xoom will restart. Once the red M appears, wait 3 seconds and then press vol-down. It should ask you what to do (display --> Android Recovery). You can change the option with von-down, select with vol-up, highlight Android Recovery and select it with vol-up.
if this suceeded, you should be in the ClockworkMod recovery (Your background image should now be a green robot). If not, you have to restart with flashing the recovery. Do not boot into android as, depending on your OS-Version, it will reset the recovery to stock.
backup your system
Why would you want to backup now, this system is as stock as it gets??? Exactly, maybe you will want to revert back to a stock xoom, so keeping a backup of this will be nice
Right now you are in the Clockworkmod-System, controls are: vol-up/down: cursor up/down; power: select
using the vol-down-button on your xoom, navigate to "backup and restore" and hit the power button
make sure "Backup" is highlighted, hit power to start the backup process. It will backup basically everything from your xoom onto your sdcard
after this is done use the "+++++Go Back+++++"-links to go back to CWMs main menu. Do not reboot, as this will probably delete CWM
root your xoom
If you root your xoom, you will be able to do much more on your xoom. The universal xoom root update.zip will also prevent your xoom from deleting the Recovery upon boot.
using vol up/down, navigate to "install zip from sdcard", hit power to select
use "choose zip from sdcard"
pick the Xoom-Universal-Root.zip
find the entry that says "yes"
once that is done, "+++++Go Back+++++" until you find an entry "reboot System now", hit that one
Your xoom should now be unlocked, rooted and be equipped with a new recovery system. To install a custom rom, reboot into the recovery (reboot the xoom, when the red M appears, wait three seconds, hit vol down, then vol up) and just install the custom roms update.zip. Be sure to follow the roms installation instructions, you might need to wipe certain partitions or manually install more than one package (for example for the google applications)
All credits go to creators of the downloaded files, I assembled these instructions from their threads or other informations. I have not created a single of these files.

Thank you so much!!!: That was just what I needed. Thanks for all the amazing detail, I will try it in the next couple of days when I built up the courage!
Amazing guide!!! You should set up your own thread or send it to solarnz (the guy who mad the universal root).
UPDATE: In the part where I flash recovery.img , You told me that I should shift+right-click ,then open command window and type adb devices. adb isn't recognised in the desktop - xoom folder, however it works if I run it from C:\android-tools. Do I need to place the recovery in the android-tools folder?

So, i can just copy the .zip from here (http://forum.xda-developers.com/showthread.php?t=1488075) onto the root of the SD card and then follow your instructions above?
Edit - I've already unlocked and rooted

yes, but be sure to pick the right .zip-file for your xoom. AFAIK, the bugless beast is not available for european or us 3g xooms. Using a zip that has been made for another model may permanently damage your xoom (some MZ601 users reported that they were unable to get 3g working again after installing a MZ604-rom, not even after installing official MZ601-rom)

i THINK it should be comparable to the EU-xoom. What's your model number? It should be printed on your box and, if you haven't flashed any custom rom yet, in your xooms settings. It should read MZ60*.
MZ600 is the US-3g-model for CDMA-Networks.
MZ601 is the EU-3g-model for GSM-Networks.
MZ602 is the MZ600 upgraded with the LTE-Module.
MZ604 is the wifi-only-model
if you can't find a bugless beast-rom for your xoom, I'd recommend the team EOS nightlies, work really niceky for me

I followed these instructions. When I got to the point of installing the new ROM I ended up at the bot with the "!". What do I do now?

you are talking about the standard-android-bot, and it shows up after trying to reboot into recovery, right?
That means, that the recovery has been overwritten w/ the stock recovery. This happens when you don't root after installing the cwm recovery and before rebooting, or if the rooting fails.
If you already made the backup, you should be on the safe side, just go ahead and redo the section "installing ClockWorkMod". at the end of thiis section, you should be in the recovery, just install your rom from there, skip the backup- and root- sections and do not reboot before the rom and gapps-packages have been installed.

Boot screen
Thanks Llama.
I did what you said. After flashing ROM (i think) and loading Gapp I rebooted and now it is just on the red M screen and doing nothing else. Please help! I can get back into clockwork recovery. what am I doing wrong. As if its not obvious, I'm a total noob.
edit: Wow! Somehow I got it to work. I now have EOS rom. Thanks everyone!

Did something wrong
Okay, I have the EOS rom, but I can't find any of my apps. I thought I backed up everything on my internal storage. I loaded the backup into the internal storagage after the flash, but no apps. Maybe I didn't backup the apps properly. I don't have adroid market on the new rom, and cant download any of my apps from market or amazon. ICS is great, but not much use without apps. I can't even download new apps. What am I missing?

do you have the google mail app? Android market is usually part of the gapps package, maybe you didn't install that package correctly?
I'd try to do a factory reset (wipe /data, /cache and dalvik-cache from recovery) and install the gapps .zip again.
how did you backup your apps? If at all possible, you should not reatore apps using titanium backup or something like that after upgrading from Honeycomb to ICS. Instead, you should install these apps from market manually and only restore those apps that you can't find on the market.

factory reset
So I go into clockwork recovery and "wipe data/factory reset"? then do i "wipe cache partition" or do I wide data before factory reset? After factor reset were do a start back in the procedures you decribed in detailed post? I really appreciate your help!

I am not entirely sure if you even have to wipe the cace partition, as a factory reset should also wipe the cace-partition. But just to play it safe:
go to recovery
wipe /cache partition
advanced->wipe dalvik-cache
wipe /data/factory reset
install zip from sdcard-> pick the gapps .zip
reboot
you do not start back in tzhe instruction, as they never described installing custom roms;-)
also, make sure you use the current gapps .zip, that should be release 10.5

sd card?
I did what you instructed with no problem. I ensured that gapp v10.5 is the one I have on my sdcard(as viewed on pc). But when I go to select .zip file from sdcard (from clockwork recovery), I get a menu that has the files I had on my internal storage, and the gapp.zip is not there. There is also a 'ifx_permissions' file on my internal storage (viewed on pc), and there are files that were not wiped out (files for apps).

which recovery did you flash? Did you use the Tiamat-modded recovery I recommended in post #2? With that recovery you shouldn't be able to see the internal memorys contents, instead you should only be able to see the sd-cards contents.
When booted into recovery, the first line should read "Clockwork Mod Recovery v3.2.0.0 (solarnz-R4c-100611-1150)". If not, please flash the recovery image I recommended in post #2, according to the section "Installing ClockworkMod". After that, do what I wrote in post #16.
If you still have problems after that feel free to ask some more, glad I can give back a little of my knowledge

Magnanimous Gratitute
llama,
you are a scholar and a gentleman. I think I am finally up and running. I was entering recovery from ROM recovery. After your tutelage all is in order. I have Market now and apps are downloading. One final (i hope) noob question. How do I thank you (on the thread). You have certainly earned it!

[A511/A510] [01-07-2012] CWM Recovery - TESTING only (can cause bricks!!)

Hi all,
Well, it looks like it works now!
Touch is also available, built through the builder of CyanogenMod (turned out I used the wrong recovery, I now used boot.img from the 1.011 ROM). Use the power button to go back one step (up one level in the menu).
For the non-touch version you can use Volume+ (one dot) and Volume- (two dots) works and use power to select an option.
** WARNINGS **
My device is hard-bricked due to the restore function not working correctly... be careful what you do!
Extra WARNING - do not use:
WIPE DATA/FACT. RESET
FORMAT PARTITIONS
BACKUP/RESTORE
FOTA
1. Avoid FOTA (software update from Acer, directly on device), see update here
2. I have not tested each function yet!
3. Step 12 below seems to have a problem. Sometimes the recovery does get corrupted and needs to be reflashed.
4. Try to not use wipe/backup/restore features - only install from zip has been tested and works
** Downloads **
EDIT FROM THE ARCHANGELULLED LINKS TO AVOID BRICKING DEVICES
** Uninstall **
Uninstall has not been tested in most cases. Please let me know whether this is sufficient and whether it works.

** Install instructions **
1. Boot your device
2. If it's already unlocked, skip to step 7
3. Type following in a DOS-prompt:
Code:
adb reboot bootloader
4. Wait till device is booted and reconnected to pc (ie. drivers loaded)
5. Type following in a DOS-prompt:
Code:
fastboot oem unlock
6. Be quick (it times out) to unlock the device. Use Volume- key to highlight the unlocked lock and press the Volume+ key to activate
7. Type following in a DOS-prompt
Code:
adb reboot-bootloader
8. Wait till bootloader is loaded and reconnected to pc
9. Type following in a DOS-prompt:
Code:
fastboot flash recovery XXX.img
(replace XXX with the image file name of your choice)
Remark: step 10 to 12 can be skipped if you'll also root your device with my root-cwm-zip. That already removes the same file, so you shouldn't experience this issue
10. Reboot the device and hold to Volume- button to load the recovery
Make sure to do this - if you do not, it will automatically overwrite your recovery
11. Try to mount system. Be carefull what buttons you press. You can use power to cancel any menu and go back one menu
12. When system is mounted type the following in a DOS-prompt:
Code:
adb shell
cd /system/etc
mv install-recovery.sh install-recovery.old
13. Reboot and see whether you can still use your system. Reboot again with Volume- and see whether you can still access recovery (or use the following command)
Code:
adb reboot recovery
I will make this all much simpeler with a dos script, etc., as soon as the recovery correctly works.
** RECOVERY-A51x-tools.zip **
For quick usage I added the tools that I use to write recovery (adb, fastboot for writing the recovery to the device - batchfiles are included with each recovery download).

Great news

It seems that I can't flash update.zip anymore (1.011 ROM or FOTA)
I desperately need a stock recovery.img because my system is not working anymore (I've installed this Recovery, and then tried to apply the FOTA update: when it reboot to recovery the flash seems to have had some errors. On system reboot the tablet is stuck on Acer logo). I can't flash the 1.011 ROM anymore

See attached recovery for A510. I'm quite sure it works for A511 too.
Did you try to enter recovery using "adb reboot recovery" or by power off, power on with Volume- and wait for recovery? And did you put the 1.011 ROM (update.zip) into the external sdcard?
Flash recovery with:
1. Reboot into bootloader with:
Code:
adb reboot bootloader
2. Enter the next command from the folder with the recovery.img:
Code:
fastboot flash recovery recovery.img
By the way, I've managed to get into bootloader mode by using Volume- and switch the rotation lock back and forward at the same time...not sure whether there's another way (other than booting the device and rebooting into bootloader with the adb command).

Nika.

Maybe some more details from your side are good as well.
1. Why did you install the 1.011 update.zip using the recovery? See also next question
2. Did you try install update.zip (put in external sdcard and name it update.zip!) using the regular recovery? In my case it always first tries to do update.zip and then goes into the recovery
3. Make sure the update.zip is correct on the external sdcard. Maybe copy it back and unzip to see whether it's not corrupt
Yesterday I also tried installing another zip that I created myself (to see whether I can get root somehow) and running the zip works fine, so it definitely works!
Regards,
Nika.

OP changed. It works now. It's not touch recovery, but using Volume+ and Volume- works and use power to select an option.
** WARNINGS **
1. I have not tested each function yet!
2. Step 12 below seems to have a problem. Sometimes the recovery does get corrupted and needs to be reflashed.
Believe it or not, my first version of the recovery was very close. I just had some problems due to invalid BoardConfig.mk entries which I had used from the Dees-Troy recovery source. I have now used the ones that were generated automatically when using the CWM-recovery-build-website (which generated the touch recovery but seems to have the before mentioned issues)...

1. I've installed the 1.011 update.zip (via stock recovery) yesterday and all went fine. Then today I saw your recovery and I flashed it. Then I saw the FOTA alert, I've pressed "Update", but when it went to flash it I saw an Android with a red triangle, and on restart the tablet is stuck on Acer logo.
2. Yes, but it goes straightly to your recovery. And if I flash 1.011 update.zip with your recovery I see only an Android robot, it seems that it can't flash it for some strange reasons. And I can't see the bottom part of the recovery, it's zoomed so I can't know what's happening.
3. It's the same .zip that yesterday worked, so it's not corrupted
Now the situation got worse..I tried some other things (other recoveries for A510 like Thor's or TWRP) but didn't get to solve. Now I think that the battery is dead, and I'm charging the tablet from 1 hour (but it's not booting anymore: nothing happens when I press power button, the screen doesn't turn on...I hope it's not definitely dead ) so I can't try the above method

When you only installed the recovery as recovery you should be ok. Bricks only happen when you flash a new boot record... I've also tried TWRP's but didn't have any issues so far, other than that they didn't work.
Remember the tablet doesn't charge when USB connected (unless using the charger). In my case that's one of the reasons I had to stop yesterday
When it runs again (hopefully) try my new recovery. Get into bootloader mode with the Volume-, Poweron, screenrotation lock method and flash it with "fastboot flash recovery recovery.img". If it's locked again (which happens after flashing roms, it will then complain when you try to install the recovery) run "fastboot oem unlock", reboot with "fastboot reboot" and try again to flash the recovery.
Good luck and keep me (us) posted

The tab is completely dead
I've charged 100% (white LED), but the screen won't turn on.
I only noticed that if I connect the tab to pc via USB there is a new device called "APX" in "Other devices".
Checked some A500 threads and it seems APX mode is to flash bootloaders
But nothing for A510\1...so it's dead

That's horrible also for others because it will make the choice to install this a little harder... although I honestly have not had any of your trouble, and I don't really understand what happened either
But.. definitely check on google. I have seen many successful recovery from APX-mode.
Good luck and keep us posted.

root or cwm? I guess I can build CWM for A510 too, but you have TWRP and CWM already don't you (on other forums...)?

we have root but no working recovery..
Twrp first not allow the swipe to unlock
cwn release from EB launch but only backup works, not restore.
Any help would be appreciated

Ok... will build it as soon as I can (takes some time to setup the env). I haven't tested restore btw, need to backup some more stuff (with titanium backup) to make sure I don't loose anything
Also, make sure you have a large enough external sdcard when making backups. Remember the internal sdcard is huge and backups can cause the external to be full
One more thing, also good to know, you can always backup using DD commands:
Code:
dd if=mountpoint of=/sdcard/filename.img
And here's a list of the mountpoints in the A510/A511:
Code:
/dev/block/platform/sdhci-tegra.3/by-name/SOS /dev/block/mmcblk0p1 /recovery
/dev/block/platform/sdhci-tegra.3/by-name/LNX /dev/block/mmcblk0p2 /boot
/dev/block/platform/sdhci-tegra.3/by-name/APP /dev/block/mmcblk0p3 /system
/dev/block/platform/sdhci-tegra.3/by-name/CAC /dev/block/mmcblk0p4 /cache
/dev/block/platform/sdhci-tegra.3/by-name/MSC /dev/block/mmcblk0p5 /misc
/dev/block/platform/sdhci-tegra.3/by-name/FLX /dev/block/mmcblk0p6 /system/vendor /flexrom /flex
/dev/block/platform/sdhci-tegra.3/by-name/AKB /dev/block/mmcblk0p7 ?
/dev/block/platform/sdhci-tegra.3/by-name/USP /dev/block/mmcblk0p8 /aboot (bootloader.blob)
/dev/block/platform/sdhci-tegra.3/by-name/DE2 /dev/block/mmcblk0p9 ?
/dev/block/platform/sdhci-tegra.3/by-name/UDA /dev/block/mmcblk0p10 /data
So you can use these commands:
Code:
dd if=/dev/block/platform/sdhci-tegra.3/by-name/SOS of=/mnt/sdcard/recovery.img
dd if=/dev/block/platform/sdhci-tegra.3/by-name/LNX of=/mnt/sdcard/boot.img
dd if=/dev/block/platform/sdhci-tegra.3/by-name/APP of=/mnt/sdcard/system.img
dd if=/dev/block/platform/sdhci-tegra.3/by-name/CAC of=/mnt/sdcard/cache.img
dd if=/dev/block/platform/sdhci-tegra.3/by-name/MSC of=/mnt/sdcard/misc.img
dd if=/dev/block/platform/sdhci-tegra.3/by-name/FLX of=/mnt/sdcard/flexrom.img
dd if=/dev/block/platform/sdhci-tegra.3/by-name/AKB of=/mnt/sdcard/AKB.img
dd if=/dev/block/platform/sdhci-tegra.3/by-name/USP of=/mnt/sdcard/bootloader.img
dd if=/dev/block/platform/sdhci-tegra.3/by-name/DE2 of=/mnt/sdcard/DE2.img
dd if=/dev/block/platform/sdhci-tegra.3/by-name/UDA of=/mnt/sdcard/data.img

Well... I tried making a backup in my CWM and it says "Error while making a backup image of /data". Not sure yet why... will first make some dd backups, titanium backups, wipe device and will then start testing from scratch...

Sorry for spamming, please provide a boot.img of your device/rom-version so I can use that kernel for building the recovery.

Touch is now also available, built through the builder of CyanogenMod (turned out I used the wrong recovery, I now used boot.img from the 1.011 ROM). Use the power button to go back one step (up one level in the menu).
See first post

Problem with CWM
Great work. Only problem what I have is that my device is not recognized when entering CWM. In the device manager is just an unknown device. I have installed the drivers from the Acer support. Do I need somehting else, too?

Well, my A511 is stuck at "writing recovery".
Bootloader vICS-MR1-89805f0(UnlockMode) :
sending recovery 5268kb ...
OKAY 2,063s
writing recovery ...
FAILED status malformed 0 bytes
finished. total time 503.062s
Well its still booting without problems in unlocked bootloader, but i cant flash. It just stuck there even if i try it again and again.
A511 & NV Fastboot Driver are both recognized by my system, but can it cause an error that i run windows in a VB? Need to enable USB-Debugging to run adb.
I never had problems with my Arc before using fastboot in a VB.
EDIT: Same for the touch-CWM. It just stuck at writing recovery.
adb v1.0.29

3 doubts about flashing CWM and EOS ROM

Hi all.
I have an Spanish wifi-only Xoom (MZ604) and I'm tired of waiting for motorola's updates (still in Honeycomb 3.2!!!).
I want to test either EOS3 (Android 4.1.1) or EOS2 (Android 4.0.4) custom roms. I've read almost all tutoriales but I still have some doubts about the procedures... could anybody check this message and warn me if I'm going to do something wrong?
DOUBT 1.- Key shortcuts in Xoom
Can anybody tell me the existing key combinations in Xoom? I only know about POWER+VOL_UP key to enter bootloader mode.
DOUBT 2.- How to install CWM.
If I understand it correctly, both EOS2 and EOS3 should be installed from CWM recovery...
Is the following procedure OK?
- Some tutorials say that you have to be root first to install CWM ... is it really needed? Can't be done directly with ADB?
- Install Android SDK in the PC.
- Download eos-recovery-r6.img or eos-recovery-r6-softkeys.img
- Connect XOOM to PC with the original USB cable.
- Reboot XOOM in bootloader mode (Power + VolUp)
- Exec adb and then:
fastboot oem unlock <---- is this a requirement?
fastboot flash recovery eos-recovery-r6.img
fastboot reboot
DOUBT 3.- How to install or upgrade EOS 2 or 3 ROM?
Is the following procedure OK?
- Download ROM and gapps zip files.
- Start XOOM in recovery mode (CWM) -> How to do this?
- Do a nandroid backup.
- Wipe everything (data, cache, dalvik, etc)
- Install ROM zip.
- Install gapps zip.
- No need to do anything to root it, the rom is already rooted <-- is that right?
- Reboot
Is everything OK? Did I miss anything? Do I need to root my 3.2 install before any other step? Do I have to do the "oen unlock"?
Thanks.

All you need to do is unlock your boot loader and get into flashing eos3. Will give you details how to soon

Thanks for answering. If I'm understanding you correctly, you say that I don't need CWM and I can just flash the EOS ROM directly to my xoom without "applying" it as a zip in CWM...
I would really like to install CWM, I appreciate a lot the possibility to do "nandroid" backups to be able to go back before installing kernels, updates or so ...

Since you are going to install EOS Jellybean, I don't advise you with CWM. A different recovery made by EOS team is better through which you can do nandroid backup and other stuff...
Here is what you need to do step by step...
Note: please read this procedure carefully more than once until you are fully aware of it. If you have any doubts or concerns, just ask to avoid confusion before you apply. This should be followed step by step.
To summarize:
First, download the above ROM and GAPPs and put them onto your xoom internal and external SD card. Put them under /mnt/sdcard for internal sd or somewhere accessible, and under the root of your external sd card.
To download:
• Get the Motorola USB drivers to your laptop: http://developer.motorola.com/docstools/USB_Drivers/
• Get the Android SDK to your laptop: http://developer.android.com/sdk/index.html
• Recovery Image: http://goo.im/devs/teameos/recoveries/wingray/eos-recovery-r6.img
• GAPPS: http://goo.im/devs/teameos/roms/eos3/gapps/gapps-jb-20120726-eos-signed.zip
• ROM: http://goo.im/devs/teameos/roms/eos3/nightlies/wingray/ ; get the latest one...
Steps:
1. Power off your XOOM device.
2. Press and hold the volume down button while pressing the power button at the same time. Note: Even if your xoom starts again, just keep the button pressed until you see "Starting fastboot protocol" on the screen.
3. Connect Xoom to your computer via USB.
4. Open a ‘Command Prompt’ or ‘Terminal’ window on your computer in your sdk/tools folder. This is the sdk you downloaded above.
5. unlock your xoom and flash the recovery image. The recovery image should be in your current working directory where you have command line navigated to: Type:
adb reboot bootloader
fastboot oem unlock
fastboot flash recovery eos-recovery-r6.img
fastboot reboot
adb reboot recovery
Now, you have your device unlocked and recovery installed.
Reboot your xoom by selecting the option "reboot system now" from recovery. you can navigate up and down using the volume buttons. Once an option is highlighted, press the power button to select, you will still have your old ROM.
To flash the other ROM downloaded above,
1. Boot into recovery by:
i. As soon as you hit the reboot command above, you should see a Motorola logo appear. Wait 3 seconds and tap the Volume down button and the words Android Recovery should appear on the screen. When you see that, tap the Volume up button and you’ll boot into recovery.
2. From within Recovery, perform wipe data, wipe cache, and go to advanced, wipe dalvik cache and battery stats. Don't worry, if the ROM and GAPPs are deleted, which should not be the case, you will have them on your external sd card
Note: wipe data will delete your stuff on the xoom. It would be great if you backup your files that you need to your external sd card before you start any of this procedure.
3. In recovery, navigate to install zip from sdcard > choose zip from sd card and select the EOS ROM you copied to the root of the SD card. Once the files are flashed, DO NOT reboot afterwards. Hold on.
4. Again, from Recovery, choose install zip from sdcard > choose zip from sd card and select the GAPPs you copied to the root of the SD card.
Then hit reboot system now. It will take 2 - 3 minutes for the first reboot. Setup your google account. and you are good to go.
Later reboots will be much faster (around 30 - 45 seconds). The more apps you install, the slower it boots...
That is pretty much it. Enjoy, I hope this helps you

Of course it helps! In fact, a lot.
When I was talking about CRW I really meant EOS recovery (which is based in CRW itself IIRC).
The only that I can't understand is why some tutorials ask me to root the tablet before doing all this process...
Anyway, I think I'm finally going with EOS3 + EOS recovery if nobody here advices me to flash EOS 2 instead...
Sent from my Samsung Galaxy S2 using Tapatalk Pro.

So, before flashing:
- Do you think EOS3 (JB in Xoom) is mature enough to use it, or I should go with EOS2 final (ICS)?
- Do you know of anything not working in a wifi xoom with EOS3 rel.127?
- I've downloaded eos6-recovery.img ... do you think I should flash the "soft-keys" or the rogue-recovery instead?
- I don't have Microsoft Windows in my laptop: I work under Linux, so I haven't downloaded Motorola's USB drivers... I imagine that they are not needed under Linux, and It will work just with SDK's "adb" and "fastboot", right?
- Can the device be bricked with this procedure, or there is always a "Power+VolKey" way to flash a stock image? (like galaxys2 that its almost unbrickable).
PS: Thanks for informing me in the other thread that the EOS rom comes already rooted

I will be away for couple of hours, will answer your questions all as soon as I get back...

Alright, eos jelly bean is fully stable, ,such faster and smoother than ICS. You want feel the difference until you try it... however, eos ICS is stable too and has more features and addons by eos because it has been there under dev for longer time, jellybean is new, one month old only... I recommend you to go for jellybean, and try and see for yourself. At anytime you can flash ICS since your Xoom booloader is already unlooked and recovery installed, you can do that by just wiping data and flash ICS zip. That is as simple as that...
For Motorola drivers on Linux, I think it is not needed, adb is built in with Linux, but I am not sure as I haven't tried that yet.
For eos recovery, don't use the soft key version, use the normal one...
with this recovery, you will be safe, because at all times, your external SD is accessible in emergencies...
Hope that helps...

You have it down perfectly. Just to recap.
1. Set up android sdk. Download recovery image and store in sdk folder. Download rom/gapps and store on tablet.
2. Boot into fastboot (power + volume up).
3. fastboot oem unlock (required). This will wipe all data.
4. fastboot flash recovery recovery.img (whatever recovery you decide to go with, I recommend eos soft key).
5. boot into recovery, make nandroid backup, flash rom of your choice + gapps if necessary.
People tie rooting to flashing custom roms because many people have become so reliant on apps like rom manager that flash the recovery for you, an app that requires root access. I never rooted my galaxy nexus or xoom. I simply flashed recoveries in fastboot and proceeded to flash roms in recovery.
It actually bothers me how some have become so reliant on root access to flash roms. It has gotten to a point where many people genuinely don't know the difference and that, to me, says they don't really understand what it is they're doing, which will lead to issues should they ever need to troubleshoot.
You seem to have it down well though. Good luck.

Thanks a lot to both.

Ok. EOS6-RECOVERY installed correctly. There are a couple of mistakes and some missing info in the "tutorial", so I'm going to change it to help future users:
I finally did it under Windows because almost all tutorials in Internet explain all the possible problems that you can find in Windows, and it's a "too risky" task for me to "experiment" by myself.
PART 1 .- HOW TO INSTALL EOS6 RECOVERY:
Originally quoted from wesamothman:
First, download the above ROM and GAPPs and put them onto your xoom external SD card. Put them in a folder called /sources/ of your external sd card.
- Get the Motorola USB drivers to your laptop: http://developer.motorola.com/docstools/USB_Drivers/
- Get the Android SDK to your laptop: http://developer.android.com/sdk/index.html
- GAPPS: http://goo.im/devs/teameos/roms/eos3/gapps/gapps-jb-20120726-eos-signed.zip
- ROM: http://goo.im/devs/teameos/roms/eos3/nightlies/wingray/ ; get the latest one...
And the most important:
- Recovery Image: http://goo.im/devs/teameos/recoveries/wingray/eos-recovery-r6.img
Check that the md5sum of this file is correct and matches with the one provided in the download page. This is the most important file because it will allow to install the CWM recovery system and it's CRITICAL that the file is not corrupted.
Steps:
a.- Install in your PC the lastest JavaSE JDK from Oracle's website.
b.- Install in yout PC Android SDK, open Windows' cmd, enter the android-sdk folder and run:
Code:
tools\android.bat update sdk
Now select "Android SDK Tools", "Android SDK platform-tools", and Extras/"Google USB Driver". Click on "Install packages".
c.- Enable USB debugging in the XOOM (in settings, development).
d.- Install the Motorola USB drivers for your laptop (32 or 64 bits, check it in the Windows system properties).
e.- Plug the Xoom to your laptop.
f.- Execute cmd and enter the android-sdk/platform-tools folder.
Run "adb devices", if you get an empty "List of devices attached", then you must enter the control-panel -> devices and "Fix problem with device" over the MZ60x device. After a While, Windows will fix it and "adb devices" will show a message like:
Code:
List of devices attached
037887sda897xz device
(the digits string will vary according to your device)
NO NEED TO DO THIS:
NO -> 1. Power off your XOOM device.
NO -> 2. Press and hold the volume down button while pressing the power button at the same time. Note: Even if your xoom starts again, just keep the button pressed until you see "Starting fastboot protocol" on the screen.
Because the first command show after this lines: (adb reboot bootloader) won't work while in fastboot. Only "fastboot" commands work in fastboot mode. If you try that command in fastboot mode, it will say "Error: device not found".
So just, with your xoom working under the Android OS, do:
Code:
adb reboot bootloader
With the above, you'll enter fastboot mode without needing to press any key in the startup.
Now your Xoom will show the Motorola logo and the words "Fastboot protocol...". If you need to stop now for any reason, you can abandon this mode safely and reboot the tablet with "Power+VolUP+VolDown" for a few seconds.
But let's continue.... If you now do:
Code:
fastboot devices
You should get a string like
Code:
List of devices attached
037887sda897xz fastboot
If you don't see that string (and you see and error about device not found), you have to "fix/repair" the usb drivers again in the Windows ControlPanel / Devices. Now you'll see a "FASTBOOT" device instead of the MZ60x you repaired before (that's why we have to repair/fix again the device, because WIndows see it as a different device while in fastboot mode).
After repairing it, unplug and plug the USB cable (still in fastboot mode) and repeat the command:
Code:
fastboot devices
Now it will work and you'll see the device recognized by "fastboot"
Issue the following command to unlock the Xoom (you'll void the warranty):
Code:
fastboot oem unlock
Follow the Xoom's onscreen instructions to unlock the bootloader. You have to use VolDown to move through options and VolUP to accept an option.
The xoom will reboot and your old android OS will show, but now with a factory reset. Select language, time, etc and enable again USB debugging and execute in the PC:
Code:
adb reboot bootloader
(to start again the tablet in fastboot mode)
Now copy the file eos-recovery-r6.img to the android-sdk/platform-tools/ folder and execute:
Code:
fastboot flash recovery eos-recovery-r6.img
You will see something like:
Code:
C:\Users\sromero\Desktop\android-sdk-windows\platform-tools>
fastboot flash recovery eos-recovery-r6.img
sending 'recovery' (4114 KB)...
OKAY [ 0.499s]
writing 'recovery'...
OKAY [ 1.014s]
finished. total time: 1.529s
Check in the xoom's screen that the file was correctly written and execute:
Code:
fastboot reboot
You xoom will start again in Android OS mode. Execute:
Code:
adb reboot recovery
And you'll start the nice EOS Recovery (based on Clockworld Mod) recovery system.
You can also do it manually by powering on the Xoom and when the motorola logo appears, wait 3 seconds and press VolUp.
Now, you have your device unlocked and recovery installed. Now, you are SAFE because you can do nandroid backups and restores and can put any ROM in your system and go back with a backup or flash another different rom.
PART 2 .- HOW TO USE CWM / EOS RECOVERY
Code:
Up -> VolumeUp button
Down -> VolumeDown button
Select -> POWER button
PART 3 .- HOW TO INSTALL EOS3 ROM:
Under recovery mode (abd reboot recovery), do:
- Backup/restore -> backup to external SD.
- Wipe data/factory reset
- Wipe cache
- Advanced -> Wipe Dalvik Cache
- Advanced -> Wipe Battery Stats
- Install ZIP from SDCARD -> /sources/ -> the eos3 rom .zip file.
- Install ZIP from SDCARD -> /sources/ -> the gapps .zip file.
- Reboot
- Enjoy your new rom!

No... thank you for the initial info
After restarting, I have a notification about a ROM update (128). The ROM-management app allows me to download it or apply a incremental update...
Do you know if that second option (incremental update) is safe?
Anyway, I can just always do a Nandroid and test it ... having CWM I can't loose never anything, right?

Of course it is safe, I use it a lot. Just boot into recovery now by long press on power menu, select reboot, recovery,
First download build128. It will be under /storage/sdcard0/goo manager.
From recovery, wipe cache, dalvik, flash build 128, and reboot,
FYI, this latest build has theme engine now

So, the incremental update has to be flashed from recovery too?
I'll try it after a few days, when people confirms that it has not any major bug...

Worth noting that to use fastboot and stuff, you only really need to install the Android SDK Platform-tools, maybe the regular SDK tools as well, I can't remember.
You don't need to install all the other stuff.

Yes, any updates/mods/gapps updates need to be flashed in recovery.
Unless specified that its necessary by devs though, you don't need to wipe anything. I've been on JB nightlies from day 1 and I haven't wiped cache or anything since the initial wipe.

Is it possible to...
a.- change the system font (too 'light' in my xoom).
b.- disable jellybean UI animations...
?

I don't know about question a, though I'm sure its possible.
As for question b, try a different launcher. Apex launcher and nova launcher are both popular Android 4.0+ launchers (check play store for them).

Eos ROM,m settings, developer options, disable animations and transitions

Software You Will Use/Need (depending on your root method):
http://support.acer.com/us/en/product/default.aspx?tab=1&modelId=4318 ← Acer USB Drivers
http://developer.android.com/sdk/index.html ← Android SDK
General Information:
First off, this was never made adequately clear for new users (without going through a hundred different posts with hundreds of replies): You will be using the Android SDK and the Windows Command Prompt. When installing the Android SDK, change the directory to something easy like C:\SDK because you will be typing it a lot. The directory in that folder you will be using exclusively for this process is the “platform-tools” directory. This is where adb and fastboot are found.
In addition, you will need to activate ADB Debugging on your tablet. This is found by going to Settings -> Developer Options -> USB Debugging. If this isn’t done, you will get nothing accomplished. Yes, you will need to have your tablet connected through USB to your PC for this to work. I know there are other ways, but I’m writing this with brand new users in mind.
After you’ve got that set, you should go ahead and install the Acer USB Drivers. None of my computers could properly identify the tablet without the drivers. Speaking of quirks, 64GB microsd cards are not generally very friendly with CM10 or CWM even when formatted as Fat32. There are lots of issues I can’t find a workaround to. Consider using a 32GB until the kinks are worked out.
I’m also assuming you are currently running the JB OTA that was pushed worldwide in October 2012. If you are not, then there are a few extra steps when installing IconiaN. Although I compiled the instructions you’re reading, I had nothing to do with anything else. In fact, I didn’t write the codes used to install things through the command prompt….I just compiled all the information into one easy-ish to follow paper.
As usual, if anything in this causes a brick to your tablet, it was your decision. I’m just providing the information that has worked for me (repeatedly). Also, as I’m not a developer, nor am I very handy with editing files or trouble shooting things without actually handling them…….Ask your specific questions directly to those people in charge of the files (pawitp, Vorbeth, Moscow Desire, meier2009, odiv81 and alx5962). They’re the gurus at this..I am a plebe in their shadow.
TL;DR:
Install Android SDK to an easy directory.
Install Acer USB Drivers.
Unlock Your Bootloader: (codes from alx5962)
1. Open a command prompt in windows and navigate to the directory where adb is stored. For the sake of conversation, I’m going to call it “C:\SDK\platform-tools”
2. Plug your tablet into your computer through USB. It should automatically mount because you’ve installed the Acer USB Drivers and didn’t skip that step above. J
3. At the command prompt, enter the following:
Code:
adb reboot-bootloader
-- Allow the device to reboot.
4. Type Code:
Code:
fastboot oem unlock
5. Press the + Volume button to select Unlock then - Volume button to confirm.
6. Restart :
Code:
fastboot reboot-bootloader
----- I had issues on step 6. I tried that, and it rebooted to the bootloader screen. To be on the safe side without hard rebooting (not knowing what was going on), I used the command from Step 3. to reboot. This works for ICS and for JB bootloaders, I confirm I used the above steps on both.-----​7. Confirmation of your unlocked status will be seen in the upper left hand corner of the screen.
Install Clockwork Mod Recovery: (all work & codes from pawitp)
Somehow I wasn’t able to install this properly (permanently) until last night (11/09/12). I’m still not entirely sure what I did differently, but I’ll try to document it here. The safest version of CWM is 6.0.1.5. Don’t attempt anything without that version or better. I’ve heard that at this time the touch version isn’t working properly, so be sure to download the original style CWM.
To navigate CWM, the following bit of information will come in handy (especially if you’ve never used it before.) Use the ‘Vol-‘ and ‘Vol+’ buttons to navigate up and down and the ‘Power’ button to select your choice. When you have made a choice it will sometimes give a screen with a ton of “NO” options with only one “YES” option (usually near the bottom). Like any good video game, if you scroll upwards, you can get to the bottom of the screen faster.
1. Place the CWM file you downloaded into your “platform-tools” directory. For the sake of being easy to install, I changed the file name to ‘recovery.img.’
2. Open a command prompt in windows and navigate to the directory where adb is stored. For the sake of conversation, I’m going to call it “C:\SDK\platform-tools”
3. Plug your tablet into your computer through USB.
4. At the command prompt, enter the following:
Code:
fastboot flash recovery recovery.img
5. At this point, you have flashed CWM to the system, BUT you will now need to boot into CWM using :
Code:
fastboot boot recovery.img
The caveat here is that you will need to install either a custom ROM or unencumbered boot.img (kernel) NOW. If you do not install one, flashing CWM was pointless because stock recovery will overwrite it at next reboot. When prompted at reboot (leaving CWM after flashing a ROM) you should choose to keep CWM. This was sort of a miscommunication between the devs and myself, but meier2009 and Moscow Desire cleared it up.
-----Step 5. does NOT install recovery, but forces your system to boot into CWM by pushing the file to your A700 from your ‘platform-tools’ directory.-----​
For Future Reference: Enter recovery…(JB):
a. With system powered off, press and hold ‘Power’ and ‘Vol -‘
b. When the system vibrates, release the ‘Power’ button.
c. When the system vibrates a second time, slide your finger from ‘Vol-‘ to ‘Vol+.”
d. When the system vibrates a third time, release that button.
Install pawitp’s CM10.1 OR IcOdiv (A701): (all work & codes from pawitp)
Download the CM10 nightly from the official Cyanogen page and grab the Google Apps file (optional, but you won’t have market without it) listed in the links section. Despite what people say, I have always been unable to install from my external SD card. Instead, I save the zip files to the root/main directory of the internal SD. Save BOTH FILES to internal SD at this time. This has always worked for me, but your mileage may vary. You do this at your own risk, blah, blah, blah.
1. Boot your A700 into CWM using the steps outlined in Step 5. (or 6) from “Install Clockwork Recovery Mod.”
2. Backup your system by navigating to “backup and restore” by using the ‘Vol-‘ and ‘Vol+’ buttons to navigate up and down and the ‘Power’ button to select your choice.
3. At this point, there are two options for you. “backup” and “backup to external_sdcard”…. I have never been able to mount my 64GB Fat32 external_sd in CWM. Try a smaller card if you have one available (I don’t). If you can backup to external, that is probably necessary when coming from stock. I would only backup to internal if you are just updating from an older nightly or previous rom.
4. On the main screen, assuming you’re coming from stock JB or ICS, you will need to do a couple of wipes. I’m positive the first is necessary, and have read in other parts of threads and other forums that the other two wipes are needed, but as they’re both called “cache,” I went ahead and did both (with no ill effects).
Select “wipe data/factory reset”
Select “wipe cache partition”
Select “advanced” and navigate to “wipe dalvik cache”
Go back to the main menu.
5. From the main menu, select “install zip from sdcard”.
6. Select “choose zip from sdcard” and scroll down to the CM10 zip file. Press the ‘Power’ button to select and confirm.
After this has successfully installed, you can choose to install Google Apps or not. I’m assuming you will want to install them because…well…who doesn’t?
7. To install Google Apps, follow Steps 3 and 4 from above, but this time you will choose the gapps zip file instead of the CM10 zip.
8. Reboot Device & Enjoy well sorted Jelly Beans.
Install iconiaN: (all work & codes from Vorbeth)
At the moment this is my favorite. It is one version number (4.1.1) behind CM10 (4.1.2), BUT it is compatible with my SD card, and is similar to the stock experience …. only faster and without the bloatware. The only reason it is second in this guide is because of the alphabet (C before I & P before V).
The latest updates to the ROM bring the latest GAPPS and firmware. meier2009’s 4Way Reboot Mod is also included (and rocks).
1. Boot your A700 into CWM.
2. Follow Steps 2-6 from above if coming from stock JB (or CM10, or CoolOne700) with the exception that you’re installing the iconiaN zip (not CM10, duh). Also, iconiaN comes with v4.2 Google Apps pre-installed, so no need for Step 7.
-----2.a. If coming from stock ICS, you will need to install the Jelly Bean Firmware (Found in the Aroma Setup of the ROM)
3. If coming from an older version of iconiaN, you shouldn’t need to do the wipes, but go ahead and do the backup just to be safe.
4. Reboot Device & Enjoy well sorted Jelly Beans.
-----On a side note, I went ahead and installed BusyBox (https://play.google.com/store/apps/details?id=stericson.busybox) not sure if this was necessary, but I am suffering no ill effects from having it running on my tablet. -----​
Install Vorbeth's OC GPU Kernel: (all work & codes from Vorbeth)
This is a custom kernel (as of this writing available only for the A700) that overclocks the Tegra 3 from 1.3Ghz to 1.5Ghz. There has been a noted improvement in gaming performance using this kernel.
1. Boot your A700 into CWM.
2. From the main menu, select “install zip from sdcard”.
3. Select “choose zip from sdcard” and scroll down to the iconiaN Kernel zip file. Press the ‘Power’ button to select and confirm.
4. Reboot Device PLAY SOME GAMES! WEE!
Install Vorbeth’s EasyRoot: (all work & codes from Vorbeth)
If for some reason you’re happy with stock and just want a very simple way to ROOT, then this is for you. Using this kernel will cause OTA to stop working (or you will have to edit the updater-script) and remove all the file checks. The latest update has made all previous instructions null, and it is now exceedingly easy to install ROOT on your A700. Awesome! Still, this does require an unlocked bootloader.
1. Download and extract the EasyRoot ZIP on your computer.
2. Locate and double click the file 'easyroot.bat'.
3. Follow all onscreen instructions.
4. Profit.
CoolOne700: (all work & codes from meier2009)
This is the new kid on the block. meier2009 has included three different install options in this ROM including Full (rooted stock), Small (all the Acer bloatware removed), and Custom (Choose what you want.) It’s definitely one to keep an eye on. Custom install is very handy. He’s also got his 4Way Reboot Mod which adds all our favorite reboot/recovery features. Sweet! Also, BusyBox and SuperSU are included on install, so you don’t need to worry about that.
1. Boot your A700 into CWM.
2. Follow Steps 2-6 from CM10 Install if coming from stock JB (or CM10, or iconiaN) with the exception that you’re installing the CoolOne700 zip (not CM10, duh). Also, CoolOne700 comes with Google Apps pre-installed, so no need for Step 7.
-----2. a. If coming from stock ICS, you will need to install the Jelly Bean Firmware (Found in the Aroma Setup of the ROM)
3. If updating from an older version of CoolOne700, you won’t need to do any of the wipes, but it is always a great idea to do the backup.
4. Reboot Device & Enjoy well sorted Jelly Beans.

Code:
6. If upon reboot, you hit the old system recovery, you will need to reflash the recovery.img OR just work around it by doing:
Code:
fastboot boot recovery.img
-----Step 6. does NOT install recovery, but forces your system to boot into CWM by pushing the file to your A700 from your ‘platform-tools’ directory. I had to use this method to install CM10 because I was never able to get CWM to install. Your luck may be different.-----
THAT´s the Trick my Friend !
Install recovery with
Code:
fastboot flash recovery recovery.img
AND THEN
Code:
fastboot boot recovery.img
Install any ROM and if you´re rebooting and asked to FIX Recovery, answer YES, then it will be leaved there !!!
With this way your also able to start CWM Recovery temporary
only use
Code:
fastboot boot recovery.img
then CWM will start, you can flash anything and after that CWM is gone, because the Stock Recovery is always inside the Recovery Partition

Makes sense then how I finally ended up with CWM actually installed on my tablet. Were the original instructions from pawitp mistaken, or just incomplete?

ROFLMAO

Added more info last night and have now included the AOSP 4.2 to the links. Keepin' this bumped & updated.

Thanks for posting this excellent How To! I used it to install CM10.
I can confirm the backup to external backup functionality does work with a 8 GB MicroSDHC card. One thing you could do to bypass the external vs internal SD card discussion is to use sideloading. I used it to both install CM10 and the Google Apps and it works nicely. Just select Update through sideload in CWM and then enter 'adb sideload <filename>' on the command line and everything works nicely.
Also for the real beginner you could may be suggest backing up all user applications using Titanium Backup in order to easily restore them after flashing a mod.

Bumping thread back near the top. Lots of people got an A700 for the holiday and it seems many of them are bricking or at least screwing things up using outdated methods or strange new forms of CWM from other forums.
Also, thanks for the info, SanjuroE. Appreciated, and I can honestly say I never knew how to do the sideloading thing. I didn't actually realize that was what it was as on my old tablet (three years ago) sideloading was always in reference to installing from the external SD.

This guide was awesome. Many thanks for this.

Hi,
I have the same issue and it took me hours to even find a driver from ACER. But even after the installation I cannot get the tablet to work stable. I installed general MTP drivers which gave me access to the "adb reboot-bootloader" command but during the reboot the tablet gets stuck on the Acer logo screen and does not boot into the bootloader. I have to unplug the tablet and only then I get the white text in the top left corner of the screen saying "starting Fastboot USB download protocol". But that is it. I assume that fastboot would use the Acer drivers to access the tablet but I don't have any for windows 10.
My question: Could somebody post drivers for Windows 10 for the A700/A701?
Thanks

[GUIDE][BOOTLOADER,TWRP, ROOT]Lenovo TAB3 8/TB3-850F

This guide, for the Lenovo Tab 3 8" (TB3-850F), has 3 purposes:
1. Unlocking your bootloader;
2. Installing TWRP custom recovery;
3. Attaining superuser privileges (root) of the stock OS.
NOTE:
I can attest & confirm that this method has worked 100% on at least 7 devices of my own. Please read and re-read the instructions carefully before proceeding. If you follow this tutorial exactly as delineated, you should have no adverse issues in unlocking your bootloader, flashing custom recovery, or achieving systemless root of the stock Android OS.
MENTIONS & THANKS:
Based on XDA Senior Member @Hemphiz's groundbreaking root and custom recovery for this device, I am now revising this thread wth improved step-by-step instructions based on members' feedback and experiences. Thanks @Hemphiz for your research, assimilation of necessary files, and for breaking ground on this tablet. Thanks also for your granting me ownership of the thread. Your contributions are greatly appreciated by many. Thanks to the great @Chainfire for his flashable systemless rooting script. Thanks to @jemmini for compiling TWRP for this tablet. Finally, thanks to the many members who have tested this guide and provided much needed input & user experience.
DISCLAIMER: As always, please be reminded of the risk involved with flashing a custom recovery and/or attempting to attain superuser privileges of your Android OS. I will not be held responsible for devices bricked or otherwise rendered inoperable as a result of this thread. You assume full responsibility for any good or bad which may result from proceeding any further. However, with that having been said, I will provide any and all support possible. Read and follow the foregoing steps thoroughly and carefully prior to proceeding. NOTE: THIS GUIDE IS INTENDED ONLY FOR THE LENOVO TAB 3 8"/TB3-850F.
REQUIREMENTS:
1. Minimal ADB & Fastboot v1.4 (or newer) Windows Installer;
2. Windows PC or laptop (Mac may be used; however this guide is intended for Windows 7 and newer operating systems);
3. Official Lenovo USB Device Driver v1.1.21;
4. TWRP v3.0.1 for the TB3-850F;
5. ADB Driver Installer for Windows;
6. SuperSU v2.82-SR5 flashable zip.
(All files, drivers & utilities for this process are available in the below download link)
DOWNLOAD LINK: https://drive.google.com/folderview?id=1l-YN5aXmjDF3O1bHxFHVIxLKuvd847Q9
INSTRUCTIONS:
1. First and foremost, unlocking the bootloader is necessary. Also, this step is a good place to make some requisite preparations. Power on your Tab 3 and select SETTINGS once booted up. Go to ABOUT DEVICE, find BUILD NUMBER, and tap it 7 or 8 times until DEVELOPER OPTIONS is enabled. In DEVELOPER OPTIONS, tick OEM UNLOCKING and USB DEBUGGING. On your PC, install the Minimal ADB & Fastboot utilities, the ADB Driver Installer, and the Lenovo USB Driver Installer. Connect your Tab 3 to your PC with the supplied (or quality equivalent) OEM charging/syncing cable. Open a command window in your ADB/Fastboot directory, by holding SHIFT and right clicking in the desired path. In the command window, type: adb devices & press RETURN. If your device is connected properly, the command window will display a string of numbers/letters, which represent your device's serial number. If your serial number does not appear in the window, try changing USB ports, change syncing cables, or try reinstalling the ADB Drivers. Once properly connected, type adb reboot bootloader & press RETURN. Your tablet should boot into Fastboot Mode, which will be displayed in white bold letters on your device's display once complete. Once in Fastboot Mode, type fastboot oem unlock & press RETURN. Your device will prompt you to press Volume Up to proceed with unlocking the bootloader, or Volume Down to cancel the process. WARNING: UNLOCKING THE BOOTLOADER AUTOMATICALLY INITIATES A FACTORY DATA RESET. YOU WILL LOSE ANY UNSAVED VIDEOS, MUSIC, PERSONAL FILES, ETC.
2. Now that your bootloader is unlocked, you are ready to flash TWRP. Download the twrp.img file from my link and save it to your PC in the ADB/Fastboot path/directory. Also, save a copy of the file on your device's internal storage or external micro SD card. Since your device underwent a factory data reset, you will again need to enable DEVELOPER OPTIONS & tick OEM UNLOCKING & USB DEBUGGING as you did in Step 1. When you have done this, again open a command window, ensure a proper connecion, & type adb reboot bootloader & press RETURN. Once in Fastboot Mode, type fastboot boot twrp.img & RETURN. EXTREMELY IMPORTANT NOTE: this device's boot image is secured with dm-verity. Leave the /system partition as read-only when prompted by TWRP. Mounting /system as read/write at this point will result in a boot loop. Flashing SuperSU, as outlined in Step 3, will patch dm-verity and fix this.
From the TWRP main menu, select INSTALL, select the image file option in the bottom right of the screen, navigate to the location where you saved twrp.img in device storage or external storage, and commence the installation. Be certain and correctly choose "recovery" when prompted by TWRP. Now select REBOOT, then RECOVERY. Your TWRP custom recovery should now be successfully installed on your device's /recovery partition.
3. Now, it is time to root this tablet. Download & save a copy of the SuperSU v2.82-SR5 zip file to the tablet's internal or external storage. In TWRP main menu, select INSTALL & navigate to the saved SuperSU zip. Commence with installation. Systemless root mode will unpack, modify, repack and flash the patched boot image. Once done, reboot system. Your Android OS should now have full systemless root, and the /system partition may now safely mount as read/write.
TROUBLESHOOTING:
In the event your device becomes stuck in a bootloop, or is otherwise failing to boot into the OS, the following is a link to my stock firmware images thread for this device. NOTE: the following link will be beneficial only if your device successfully boots into Recovery/Fastboot mode. This link provides stock partition images of /boot, /recovery, /logo & /system. Typically, flashing the stock boot & system images will get you up & running again, and will restore the Android OS to stock condition.

Look for build number. It's usally best to determine things. I'm on TB3-850F_S100030_161209_ROW
I took the latest OTA before flashing twrp else ota will fail due to the recovery being modified. For unroot there's an option in Superssu to unroot. I would personally create a full backup via twrp before rooting, so you can revert to it if you wish

Not to hijack the OP's thread but here are my thoughts. The dead Android indicates that TWRP did not successfully flash to your /recovery partition. Sounds like stock recovery is still installed. First, place a copy of twrp.img on your device's internal storage or on an external micro SD. Try this: instead of typing the command "fastboot flash recovery twrp.img", type " fastboot boot twrp.img" (assuming your twrp file is named twrp.img. If it isn't, rename it twrp.img for simplicity purposes). This command will temporarily boot your device into TWRP recovery. From the main menu on TWRP, select INSTALL. In the bottom right of the screen, select the option for "img" files. Navigate to where you stored "twrp.img" and select it. Install it to "RECOVERY" when prompted. Once it flashes, select REBOOT then select RECOVERY. Your device should now successfully boot into TWRP recovery.

I was running into the same issue after flashing twrp.img via fastboot, it kept coming up with no command when booting into recovery. Followed MotoJunkies advice and booted into twrp.img instead of flashing and installed it that way, now my device is rooted. Thank you Hemphiz and MotoJunkie.

Hmmm. Did you execute "fastboot oem unlock" first to unlock your bootloader? It sounds as though you are saying TWRP installed correct? When you try to boot into the OS, you are getting reverted back to TWRP?

i did that. i had teamwin recovery. then installed the superuser.zip and it keeps looping

I see. The superuser zip is likely the culprit. Which one did you use? Did you use the one in the link? Here is a link for the stock boot.img for this device. Install it in fastboot mode by typing "fastboot flash boot boot.img". Try booting after flashing the stock boot image and also try reinstalling the boot script.https://drive.google.com/file/d/0B7-zQU1VihD3ZGZBRzU1Nm1PYjA/view?usp=drivesdk
Note: you will need to rename the downloaded file to " boot.img"

Thanks for the guide. Tried to do this on the Lenovo TAB3 10 Business, but no success
I can connect using the tools and enter into fast boot
When I flash, it seems successful, but after shutdown, start with power, volume buttons, I don't see the TWRP, but instead a kind of test app
When i use the other method to boot into the twrp, the Lenovo, boots normal, not into TWRP
Any ideas?

When you initially connect your Tab3 to PC and open a command window, did you execute both recognition tests? "adb devices" and "fastboot devices"? I am just curious as to whether your device is being recognized by both the fastboot and the adb platforms. Please try this and let me know.

This i what I with Lenovo Tab3 10 business
>adb devices
List of devices attached
8HSKCMT4PJIZ9HDZ device
>adb reboot bootloader
>fastboot devices
8HSKCMT4PJIZ9HDZ fastboot
At this moment, on the Lenovo Android you only see a smaal line at the bottom: =>FASTBOOT mode...
The fastboot does nt deisplay errors, but after the following command, the tablet just boots in the normal Android. On the Android device I also saw quickly the message "USB transferring OK" before booting
>fastboot boot twrp.img
downloading 'boot.img'...

On the Lenovo TAB3 10 Business I can also do the following:
Holding Vol up + Power when off and then releasing power when you see the Lenovo logo will bring up the following menu:
Select Boot Mode:
[VOLUME_UP to select. VOLUME_DOWN is OK.]
[Recovery Mode]
[Fastboot Mode]
[Normal Boot] <<==
With the recovery mode I see the following:
Android Recovery
Lenovo/LenovoTB3-X70L/TB3-X70L
6.0/MRA58K/TB3-X70L_S000020_170209_ROW
user/release-keys
Use volume up/down and power.
Reboot system now
Reboot to bootloader

Chances are the twrp isn't compatible with your device. Although the hardware all looks the same. Problem is my knowledge with Android development isn't that great. I simply read in my spare time. The twrp I found for this device on a previous xda thread, but it was more of a Q&A so I made this guide to simplify things for people. I do know that the original twrp was made here http://4pda.ru/forum/index.php?showforum=583

Worked great for me thanks. Had a few problems off at first but managed to get it done. First boot did take a little while but after that all is great
