[Q] Remove CWM on wifi xoom - Xoom Q&A, Help & Troubleshooting

I have a rooted xoom with CWM installed. I want to sell the device and go back to complete stock before doing so.
I can't get the device to show up via ADB.
I can copy files to the device - and have visited the office Mot site with their package of restore files.
I am running CWM v4.0.0.4 - and I can get into this, but I can't seem to figure out what to do next.
Thanks for the help guys.

Ugh - - I am a moron.
I downloaded the drivers from here: http://www.motorola.com/Support/US-...tware_and_Drivers/USB-and-PC-Charging-Drivers
Installed - and then plugged in device. ADB showed the device.
I then did this:
-Type "adb reboot bootloader"
-Type "fastboot flash recovery recovery.img" with the image from Motorola.
-Type "fastboot reboot" and let the device boot back into OS.
-Type "adb reboot recovery"
Done. then - rebooted device and formatted the device one more time for good measure.

[ADB] Trying to backup - Birck? Hope not

Hi! I was trying to backup my Orange Monte Carlo following a Portuguese tutorial but I'm stuck in the middle and I've got no help! Hope you can provide some! These are the steps I followed (translated)
1 - Install ADB Made Easy;
2 - Open cmd;
3 - Activate cellphone debug mode;
4 - Connect via usb (without mass storage) and install drivers if request [it was requested and i installed];
5 - Run adb devices, it should show your device [it did];
6 - Run adb reboot bootloader, your cellphone will boot in Fastboot, wich is an Android image without menus [correct until here];
7 - Run fastboot devices, your device yor a question mark(?) should show up (advance to next step), else you miss drivers [step not completed];
cmd says 'fastboot' is not recognized as a command. Now my phone is stuck connected to the computer with an adriod pick and I have no clue on what to do next!
Don't know where you were going with this but to reboot your phone just pull the battery ..
Not bricked

Thank you! Do you have any idea why the last command doesn't work? I believe it has something to do with file location... I'm trying to backup my Monte Carlo. Next steps were to "fastboot boot recovery.img" and then backup.
It should be in the platform-tools directory of the android-sdk. Verify that it's there...if so cd to that directory and it should work
I already fixed it for myself, thanks! Now I can't seem to be able to install clockwork!
Doing <<fastboot boot "C:\Users\R&J\Downloads\recovery.img">> reboots the device but doesn't enter recovery.
Doing <<fastboot flash recovery "C:\Users\R&J\Downloads\recovery.img">> , <<fastboot reboot>> and <<adb wait-for-device reboot recovery>> results the phone entering android's default recovery (no acess to backup feature).
Any way to help? Thank you!
The first command <<fastboot flash recovery "C:\Users\R&J\Downloads\recovery.img">> is trying to write the recovery.img you downloaded to a recovery partition on your device. It may not be overwriting the original recovery.
try changing permissions by doing
adb shell
su
chmod 777 /recovery
then try to flash again
Lol it seems like I have been luck enough to solve my own problems, I have sucessfully installed ClockworkMod Recovery 4.0.1.4 unofficial MoDaCo Edition using a bat file . Now I can't seem to find a way to flash recovery back to stock. I though this was an option inside the modded recovery. Any tips? Thanks again!
EDIT: I have the stock recovery file . God... this tutorials I'm folowing aren't that noob friendly...

Root and Custom CWM recovery for VSD220

I got the device which is really nice, I rooted the first night, I then updated to version 1.1, lost root as usual but luckily my copy of CWM works fine for both versions 1.0 and 1.1.
If you are familiar doing this with android phones, just follow the same steps.
Use at own Risk
Download both files. Make sure they are complete and the file sizes match.
Save recovery.img to computer, and su.zip to VSD220,
Gain access to adb for your device,
go to terminal or command prompt and type "adb reboot bootloader",
and then enter.
The screen will turn solid black,
in the same terminal type "Fastboot flash recovery recovery.img",
and enter, make sure you are in the same directory as your recovery.img.
The recovery will flash quickly, when complete type "fastboot reboot", enter.
Your device will boot up,
make sure you have Su.zip saved on the VSD220 in the directory /mnt/external_sd/su.zip,
you must have an external sd card inserted,
you can confirm this with root explorer even without root.
In terminal type adb reboot recovery,
you should have a working CWM that will allow you to flash su.zip, and perform a nandroid backup, etc.
If CWM offers to block the stock recovery, accept it.
Otherwise you will need to delete or rename /install-recovery.sh and/or /system/recovery-from-boot.p.
Enjoy Root.
This works for both version 1.0 and 1.1.
Cool, thanks!
Can't seem to get "adb devices" to come up with anything. Using Android Composite ADB Interface for driver, no luck at all.
Any help on which ADB driver to use and where to download appreciated.

Sorry, was using outdated adb.
So got adb, flashed recovery.img, recovery flashed ok, rebooted...but now when I adb reboot recovery, it reboots and then stuck on green android with red triangle.
Any advice?

Ok, I worked it out now. But for others, the problem was that recovery image was being replaced with the original on the command "fasboot reboot".
So instead, immediately after typing "Fastboot flash recovery recovery.img" I typed the following command "fastboot boot recovery.img".....AND only then did I get CWM which allowed me to flash su.zip from SD card.
Thanks for all help. Now that I have root, what changes/tweaks did you make using root?
Is there an optimum dpi to apply and are you overclocking?
Thanks.

has anyone gotten this to work lately? The device I'm playing with has 1.3 firmware on it. For some reason, I haven't gotten adb to work on this device in windows, and in ubuntu, I can adb reboot bootloader, and it goes to the black screen, but any fastboot commands, just sits there waiting for device. Any suggestions would be appreciated.

I didn't know 1.3 was available. Is this a recent firmware? I checked a couple weeks ago.
Not sure, it's not my monitor, just looking at it for a friend. when I go to about, system update I see vsd220 system update 1.3 device system version : IMM76D.UI23ED02_VSC and same info under server version
Got it sorted out after hunting on google. it does work
problem with adb
Ok so i got the device being recognized on my XP machine. Really did not have to do much. Just pluged it in and everything worked.
On my Windows 7 machine when i plug in the device i only see the MTP installed and then see VSD220 in MY COMPUTER and can browse the files. I do not see it when i "adb devices".
1) USB debugging is on/enabled
2) Both laptops have Eclipse with latest ADB and ADT tools installed
Any suggestions as to what i can do? Anyone can copy over drivers that are working with your win7 machine?

I was wondering what ROM Version is your DA220HQL on (ES I think?) and will the instructions work in Linux or other *nix like systems?
The main problem I have is that I do not have any drivers so adb in Windows XP will recognize it. It is recognized under Ubuntu 12.04 for me.
Thanks for the info! I am very excited to get this working better than out of the box!

There are a universal ADB Drivers for Windows.
Universal Naked Driver for example.

Or the following link which I have no clue about who maintains this site and how secure it is running that Exe. So please check first for yourself before yelling at me. http://adbdriver.com/
Regarding the ROM Version I was on, check the other Thread where I listed them all.

Well I got the ADB driver installed and I can use it! However I tried the root procedure and it failed to root.
When I was in the CW, the one thing it kept giving an error such as cannot mount sdcard. I checked the sdcard and su.zip IS on it, but the recovery could not locate it. I did try using the sideload method and it seemed to work, but when I rebooted and checked for root, it was not successful.
I tried this in both Ubuntu and Windows with the same result. I even performed a factory reset and tried again. And the same thing: no root.
Is there a timing issue with when to enter the commands?
The info on my DA220HQL from about is as follows:

So you were able to load CW but when you select "Choose from SDCard" it could not find su.zip? Or did you try to Mount your SDCard? Regarding the ADB Commands you can take as much time as you want. Have you used CW before?

I did try to mount the sdcard, but I got an error that said it could not mount the sdcard. That is when I tried the sideload method. When I boot up normally, the sdcard is there along with su.zip. I posted the info on my DA220HQL noting the kernel version. I went back to the post where you stated your kernel version. They are different. Mine is later than yours.
After going through everything several times, I though maybe I was doing something wrong. We went out of town so this is the first time I could sit down and check out the posts.
Thanks for your help in advance.
Thanks for all the help. I could not get this to root so we are sending it back to HSN. As a last ditch effort, I did a factory reset and tried again. And I got the same result. I do not think that the recovery while booted was able to "see" the device's partition at all, which is why I got the mount errors. In any case, I also have found that we can find it online for much less than what HSN charged us for it. I am still curious if anyone else was able to root this little gem.
Keep posting updates!
im getting the same issue
cwm is not mounting my sdcard
android is recognizing it, but not in recovery
I'm thinking I shouldn't have installed that update
there are a bunch of errors in recovery when starting
E:Can't open /dev/block/platform/omap/omap_hsmmc.1/by-name/misc (No such file or directory)
E:Can't mount /cache/recovery/command
E:Can't open /dev/block/platform/omap/omap_hsmmc.1/by-name/misc (No such file or directory)
E:Can't mount /cache/recovery/log

E:Can't open /cache/recovery/last_log
E:Can't open /dev/block/platform/omap/omap_hsmmc.1/by-name/misc (No such file or directory)
my best guess is we need a different recovery img, even though acer is the same as viewsonic
also there is no prompt to disable stock recovery being reinstalled
recovery touch is also kind of wack, have to tap below whatever I want to pick (which is also not consistent horizontally)
edit: going back to recovery, under mounts and storage, it doesn't appear to have permission to mount anything
looks like viewsonic released a rooted ROM on their support site
http://www.viewsoniceurope.com/uk/support/downloads/drivers/?prod_name=vsd220
But yeah...Acer hasnt
Perhaps this should get the ball rolling? It's funny how the US site doesn't have that
edit: wow looks like they even provided flashing tools and instructions...I just hope that this doesn't brick my unit (since its Acer not Viewsonic)...anyone else willing to give it a try?

Need help preparing Xoom for official updates

Hey folks,
I´ve ran my MZ601 xoom on EOS builds over the last 1,5 years.
Obviously its unlocked and rooted. Currently its running CWM Recovery 4.0.0.4
Now I want to go back to stock to install the latest official updates to get the updated drivers for the UMTS radio/modem module.
After that I want to unlock and get root again to use any of the lastest custom Roms again.
Switching to a touch based recovery would be nice too.
I surfed around a bit and I´m rather confused which steps I need to perform in order to do this.
I guess I need to remove root and lock the bootloader again before I can install official updates ?
Could someone please toss me in the right direction? Maybe some step-by step list?
You'll presumably want Build H.6.1-38-1 for Retail Europe from here.
Returning to stock:
Extract the files from the link above to your adb/fastboot directory if you have one. If you don't have one I've uploaded them for you here.
Connect your Xoom to your PC then open command prompt from your adb folder. (Hold shift > right click on adb-fastboot folder > click Open Command Window Here)
Type adb devices and hit enter, if no devices are listed then ensure USB debugging is switched on in Settings > Development > and tick USB Debugging, then try again.
If it still doesn't appear then download Motorola USB drivers here and try again.
If fine then run:
adb reboot bootloader​Then run the following to flash the stock image:
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash recovery recovery.img
fastboot flash userdata userdata.img
fastboot erase cache
fastboot oem lock​
Flashing userdata.img is going to remove all your files so back everything up first.
This should unroot your Xoom anyway, not entirely sure if the lock is required to receive updates, but it's simple to unlock again.
Once booted and through initial setup you should receive several over the air updates. (I believe the stock image is Android 3.2)
Unlock:
Connect your Xoom again and open command window in the adb-fastboot folder as before.
Run:
adb reboot bootloader
fastboot oem unlock
fastboot reboot​You'll now be unlocked.
Install Touch Recovery and Root:
Next download ClockworkMod Touch recovery from here, rename it to just recovery.img for simplicity, and copy the image to the adb-fasboot folder.
Download Xoom Universal Root from here.
Copy that file to your sdcard.
Then run:
adb reboot bootloader
fastboot flash recovery recovery.img​(assuming you renamed it)
Once verified, reboot by holding Volume up and Power. (Keep connected to PC and keep command prompt open)
Important: When you see the Motorola logo wait about 3 seconds and hit volume down. You should see 'Android Recovery' in the top left corner, now press volume up to enter recovery.
From recovery go, Install zip from sdcard > choose zip > and select Xoom-Universal-Root.zip
Important: After the root flashes do not reboot.
Run:
adb remount
adb shell mv /system/recovery-from-boot.p /system/recovery-from-boot.p.old
adb shell mv /system/etc/install-recovery.sh /system/etc/install-recovery.sh.old​Then select reboot in ClockworkMod recovery and boot as normal.
If you are unable to use adb in recovery, then you can enable this through Windows by doing the following:
Whilst in recovery and connected to your PC, open Device Manager, find your Xoom, usually under 'Other devices'.
Then right click on your Xoom > Update driver software... > Browse my computer for driver software > Let me pick from a list of device drivers on my computer > Pick your Xoom (either one if there's two shown)
Windows should confirm the driver installed then adb should work in recovery.
Finally, run:
adb reboot recovery​If ClockworkMod touch recovery is still there then all is good!
Hopefully I've made sense! Any questions, just ask.
Repeat of downloads:
Download Motorola USB Drivers (Device Manager) here.
Download ClockworkMod Touch recovery here.
Download Xoom Universal Root here.
Wow, what a detailed guide
Thank you sir
No problem!
Let me know how it goes, hopefully shouldn't have any problems.
Resetting worked great :good:
Right now I´m in an OTA marathon
all that unlock, root and recovery stuff sounds familiar so I don´t expect any problems.
Thanks so far :good:

Ok, so this is not working
after I flash touch recovery and do thta reboot thing I can enter touch recovery, thats fine.
Flashing universal root, fine.
THEN,
adb remount
adb shell mv /system/recovery-from-boot.p /system/recovery-from-boot.p.old
adb shell mv /system/etc/install-recovery.sh /system/etc/install-recovery.sh.old
gives me error since in recovery mode there ist no adb connection
Whatever when I choose to reboot the system, recovery warns me that it will get overwritten by boot and ask me to disable this.
Shall I do this?
EDIT: Nevermind, I decided to be a little brave and just confirmed that message.
Now touch clockwork seems to be persistent and I´m a happy Xoomer again
Sorry, I had meant to reply during my lunch break.
Edit: Realised the time on the second of your posts, so wouldn't have been much help on my lunch anyway
Well I believe I just learned something new!
Either that or I'd forgotten it asked.
I assume it disables the action rather than deletes those files.
My method was just so you can use the reverse rename in future to re-enable the overwrite on boot.
In future, not that you'll necessarily ever need this information, you can enable adb in recovery through windows by doing the following
When in recovery and connected to your PC, open Device Manager, find your phone, usually under 'Other Devices'.
Then right click > Update driver > Browse my computer > Let me pick from list > Pick your phone (either one if there's two shown)
Should confirm driver installed then adb should work.
I didn't include the above previously as I couldn't remember having to do it personally.
Glad to hear all is well though!

adb reboot recovery​If ClockworkMod touch recovery is still there then all is good!
Hopefully I've made sense! Any questions, just ask.
Repeat of downloads:
Download Motorola USB Drivers (Device Manager) here.
Download ClockworkMod Touch recovery here.
Download Xoom Universal Root here.

[Q] THL T100s MTK6592 bricked. please help

Hi All,
To root my phone and upgrade to custom ROM, I went into recovery (TWRP v2.5.0.0) to wipe mode, but instead of selecting just 'Data', 'Cache' and Dalvik, by mistake I had formatted 'system', 'emmc', 'Android Secure' and 'System' as well
Now only recovery works, can go into TWRP, but nothingelse. I cannot use SP flash tool to download as it does not connect or recognise my device.
And I tried to run ADB directly,
I can issue "adb devices" it gives me my device number.
But I cannot "adb shell" as /System/bin/*.sh doesnot exist...
I have
1. "adb remount" success
2. "adb root" got root access
but
3. cannot "adb push rom.zip /Data/rom.zip" but fails copy
and "adb push rom.zip /emmc/rom.zip" fails copy as well.
Please help me, I do not know what to do.

Toolless Mi A1 rooting guide NOOB FRIENDLY (bootloader, twrp, root, rom)

DISCLAMER: DOING THIS MIGHT RESET YOUR PHONE SO PLEASE BACKUP YOUR FILES BEFORE DOING THIS
now lets get started
download this tool (even if you already have adb and fastboot)*
https://forum.xda-developers.com/showthread.php?t=2317790
and go to your phone's settings then System > about phone and press on build number until it tells you: "you have developer options"
now go to System > developer options and enable android debugging and OEM Unlocking
now plug your phone into the pc and open the file: "cmd-here.exe" from the tool you downloaded
now type adb devices and it will probably tell you unauthorized, if it does then open your phone and click on accept
if you dont see any thing other than "list of devices attached" then download this
open it and input in, N and then Y so you dont install adb but you do install the phone's drivers
now type adb devices and you should see random numbers, if it says unauthorized just go back to when I said how to fix it
so now that everything is working type in the command prompt: adb reboot bootloader
now you should see a russian cat fixing a android machine with blue text: "FASTBOOT"
now type "fastboot oem unlock" and it should unlock your phone
now type "fastboot reboot"
--------------------------------------------------------
good, Now you have the bootloader unlocked
--------------------------------------------------------
If you are now put in the setup screen don't do it, just shut down your phone and then when it's shutdown hold on the power button and volume down buttons until you enter fastboot again
now go to this page: https://github.com/CosmicDan-Android/android_device_xiaomi_tissot/releases and download the latest boot only and regular versions
put them both in the adb (tool) folder and type in the command prompt: "fastboot boot boot-recovery.img"
if your phone doesnt do anything (doesn't do anything in the 30s after you input the command) then restart it and get it back in fastboot and type fastboot --set-active=b
and then type the previous command again, if that doesnt work then restart your phone back to fastboot again
and then type fastboot --set-active=a and the command "fastboot boot boot-recovery.img" and it should work
so now you will be in twrp, good!
type "adb push (regular twrp zip name, remember to put .zip at the end!) /sdcard/"
example:"adb push TWRP-Installer-3.2.1-with-Tissot-Manager-2.5.zip /sdcard/"
and then in your phone go to install and you should already be in /sdcard if not then go there and then tap on the zip and swipe on the thing
after it finishes installing go to reboot and then tap on recovery
--------------------------------------------
good now you have TWRP installed!
-------------------------------------------
Now its up to you, do you want to install only root or rom and root? its up to you
Root Only:
Download Magisk (you can also use SuperSU but I strongly recommend magisk)
put it in your adb (tool) folder and type "adb push (magisk's zip name, remember to put .zip at the end!) /sdcard/"
example:"adb push Magisk-v17.1.zip /sdcard/"
go to install, press on the zip file and swipe on the thing and click on restart system at the end
and congrats! you have root on your phone!
Rom:
If were talking about a treble rom then you should follow this guide: https://forum.xda-developers.com/mi-a1/how-to/treble-stock-to-treble-everything-to-t3793734 but if not you can continue using this one
download your favorite rom and download magisk (you can also use SuperSU but I strongly recommend magisk)
also go to opengapps.org choose arm64 and the android version your rom is and I recommend the nano variant
now in twrp tap on Wipe and Advanced Wipe and choose everything there (you dont have to choose micro SDcard tho) and swipe THIS WILL RESET YOUR PHONE AGAIN BUT YOU PROBABLY DONT CARE ABOUT THAT RIGHT NOW
now in the command prompt type: "adb push (rom zip name, remember to put .zip at the end!) /sdcard/"
example:"adb push RR-O-v6.1.0-20180709-Official /sdcard/"
and install it, some roms include gapps and other things in their installation for example: pixel experience. but most roms don't have that
so if you check the xda page and they say nothing about including opengapps in the rom then you should be able to fully follow the next steps.
type "adb push (magisk zip name, remember to put .zip at the end!) /sdcard/" and install it
then type "adb push (opengapps zip name, remember to put .zip at the end!) /sdcard/" and install it
now tap on reboot system and congrats! you just rooted and custom rom-ed your phone!
* "even if you already have adb and fastboot" the reason for this is because that link uses the newest version (or new enough) that is surprisingly not common in other places I downloaded adb and fastboot. the new version adds a new command that is used in the guide if you are experiencing a certain problem
I hope I helped you, if you have any questions or problems post them in the comments
a big THANK YOU
Months ago I rooted and installed a new ROM for first time in my life and, although I read another guides, with them I always break my phone, so I must flash and start again. And your guide, 4 months later, saved me again. I don't know why, really. Maybe because is super friendly. But thank you, again. The only thing I'll add is wtf to do when TWRP asks if install in slot a or b because that's the point I always mess it :'(
Thank you forever

You mean when you flash the rom it asks you which slot to install to?
