I have 2 Xoom tablets, in Germany, and I took the SD Card from one of them to put it on a new phone, the Tablet kept working fine until last week that I forgot to plug it and the battery ran out. When I charged it and started it, it didn´t work again, I got the Encryption message, nothing happens when I click the Reset Tablet either, I tried putting the SD card from my other Xoom but still nothing. I enter the Recovery mode and did a Factory Reset and the tablet was OK.
Battery run out again yesterday and got the same problem once again, but now factory reset is not working, tablet stays stuck at the "M" logo after doing it, I have repeat the operation a zillion times and nothing, it stays on the M. Plus I can´t turn it off either.
The model is the MZ604 and Android Version 4.0.4
I connected the xoom to the computer after installing the drives but it won´t recognize it. I got to do the fastboot and flashed motorolas images but nothing. I can´t do the adb reboot bootloader command because ADB won´t work, because I don´t have USB Debbuging checked, but I can´t check it now because I can´t get to settings (
What can I do to recover the tablet?
Anyone, is driving me crazy, no matter how many time I flash new images it always stays on the original, so I can´t flash any special recoveries either
I tried RDS too and after the reboot stays the same in the M logo, nothing changes. What can I do?
No ideas? :crying:
I want to save the tablet if possible.
Hi, could you explain exactly what you've tried?
In particular what you mean by "I got to do the fastboot and flashed motorolas images but nothing." and "no matter how many time I flash new images it always stays on the original, so I can´t flash any special recoveries either"
By flashed Motorola's images do you mean you flashed the stock images?
And when you say you flash new images but it always stays on the original, I assume you mean the recovery stays as Xoom default?
Let me know and I'll see if I can help.

Yes I mean stock images, and yes, it always stays on Xoom default, it never changes no matter which Recovery image I flash.
The recovery is likely reverting to default because the Xoom does this automatically each boot.
We might be able to give you a recovery that stays put but the booting issue may or may not be something worse.
Being able to fix the recovery in place is reliant on adb working from recovery itself, which I'm unsure is possible.
Whilst you seem to have reasonable knowledge of flashing and using adb/fastbbot, I'll give full instructions.
I assume you have the necessary files for fastboot so I'll skip that.
Place your chosen recovery image in your fastboot folder. (I recommend ClockworkMod Touch recovery from here)
Hold shift and right click the folder containing your recovery image and fastboot files, then select 'open command prompt here'
Your PC is now setup for the fastboot process.
Connect your Xoom to your PC.
Power on your Xoom and once you see the Motorola logo, wait about 3 seconds, and press volume down.
The screen should show the Motorola logo in the center and '--> Android Recovery' in the top left.
Press volume down twice more until the top left says fastboot then press volume up.
The screen will say 'Starting Fastboot protocol support'
Now on your PC, in command prompt run the following:
fastboot flash recovery xxxx.img
Rename xxxx.img to whatever your recovery .img file is namedOnce verified, reboot by holding Volume up and Power. (Keep connected to PC and keep command prompt open)
Again, 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, you should now see your flashed recovery.
This is where I'm unsure. Try running the following:
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.oldIf you are able to run this, this will rename the files that are reverting the recovery to default and prevent it happening again. If not, we can go ahead with attempting to flash stock images anyway.
To flash stock images download Build H.6.2-24 for Retail Europe (found here.)
Extract the files to your fastboot folder.
Again, reboot your Xoom, either by holding volume up and power, or from recovery.
And again, after about 3 seconds press volume down 3 times until the top left says '--> Fastboot' then press volume up.
Now run the following from command prompt:
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 lockThis will wipe all data on the Xoom, and hopefully reset it to stock.
Finally, run:
fastboot rebootand you should boot into Android 3.2(?), fingers crossed.
If you require further clarification or help let me know.

Thanks for the info, sadly I have done almost all that, I can´t use adb commands because I never allowed the tablet to do USB Debbuging, since I wasn´t doing anything that needed that and never thought I would need it. I think I didn´t kept the tablet connected to the PC, so I will try again and let you know if it works.
Like I said before, I'm unsure whether it'll work as I'm not an expert.
However, you may find this helps:
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.
I believe ClockworkMod Recovery enables USB debugging anyway, through modifying default.prop
I'd recommend trying the above, and/or if that fails for any reason download Motorola USB Drivers here.
Thanks again but nothing works, I tried rebooting being connected to the PC and the same thing happens, the default recovery from the Xoom stays there, fastboot shows on the command Prompt and in the tablet that everything went ok and the new image was flashed but the rebooting kills it, and I can´t use any ADB commands because of the stupid USB Debugging, if something like this can happen, Motorola should have left it open from default or at least have a fail safe in case something like this could happen. RDS also flashes an image but when it rebbots the whole thing goes to hell, it stays on the damn logo with the same images. I think I can throw the tablet to the trash :crying:
Unless its a serious hardware issue, I wouldn't trash it! It clearly has life as you're able to successfully flash and such.
I'd recommend having a look at the FAQ.

Thanks, but I have done everything, what is the good thing of a successful flash when the tablet returns to it´s previous state as soon as it reboots?
Plus I can´t use one of the most important things, adb, because of the usb debugging, I can´t get into the tablet to activated it, and even if there are recoveries which bypass this thing, I can´t flash them into the tablet, well I can, they just aren´t there after the reboot. And all this because the tablet run out of battery :crying:
ClockworkMod recovery itself allows the use of adb regardless of USB debugging setting.
I believe the command adb remount should allow it.
If adb is denied you can try what I said earlier

The problem lies with the recovery, I only have the default recovery from the xoom, it doesn´t matter how many times I flash it and everything seems to work correctly, when I restart the tablet I get the default recovery. I don´t understand why this happens, command prompt and the tablet in fastboot mode tell me the recovery has been flashed, but to use it I have to reboot and when I do I always find the same good for nothing recovery.

Hello,
I don't really understand your problem with the recovery ?
When you flash a custom recovery with fast boot, you restart the tab and after 2 or 3 second you see the Motorola Logo you push the volume down
and volume up button to enter in the new recovery.
If you flash custom recovery but restart completely the TAB without manually enter in the custom recovery, each time you retrieve the original recovery.

Here is what happens, I flash new recovery, I restart the xoom with power and volume up, when the logo appears, after 3 seconds, I push volume down, recovery option shows, I press volume up and the default recovery is still there, not the new one I just flashed.
Is really no one out there that can help? :crying:
There's nowhere stated that, however I believe you already have unlocked your bootloader, didn't you? Because it's REALLY weird that it can't flash the recovery, I mean, you left the battery run out, then after charging you wasn't able to boot normally again.
I'll think a little, but give a check if your bootloader is really unlocked, the device should have installed the recovery, and as you didn't restart it entirely (let it go after the dual core logo), the recovery should be there...

I have done the fastboot oem unlock command, should I do it everytime? I can´t use adb, because like I said, I never check the USB Debugging, which I have done in my other tablet now, don´t want the same thing to happen twice.
is it dead?

Hello Everyone. Normally I´m the quiet Reader and not the Active Poster but I need your help guys.
I have a problem since yesterday and I tried to fix it by myself with searching everywhere but couldn´t do it by myself.
What I had before:
Optipop 5.0.2 with Racer Kernel (both had Builds from January) + TWRP 2.8.1
What I wanted to do:
Flash Grogg's AOSP 5.1 and newest Code Blue Kernel
What happenend:
I factory resetted and successfully flashed Grogg's AOSP 5.1 and Code Blue Kernel but had Problems with FCing Clock and Dialer so I tried to reflash both after wiping completely (even internal storage), mounted it and put the needed new files on the internal storage.
I reflashed the Custom Rom + Custom Kernel and the newest Radio, wiped Cache/Dalvik and rebooted. It booted and the notification screen with 'optimizing apps' appeared. After that that screen went black and nothing else.
It was lit so I´knew that the device wasn´t shut down and tried to rebbot sincee nothing happened. I noticed that it was possible to reboot or shut down the device normally so there might have been a Problem with the Rom.
I retried the whole procedure and this time the notification screen didn´t show up after the boot logo and went directly to the black blank screen but i still had the possibility to rebbot/shut down the device normally. This time I didn´t wipe the whole storage and this time it got stuck at the boot logo and the Custom Recovery seems to be broken, too. The screen shows the dead Android with the red triangle.
My Problem is that I can´t connect my device to the computer, find it with 'adb devices' and reflash the Recovery with fastboot. The device is shown as 'android' in device manager in Windows 7 and nothing else. I already tried to un- and reinstall the Google drivers and that whole stuff but it doesn´t work for God's sake. adb doesn´t list my device and the 'list of devices attached' is blank although my device is connected.
I know my phone is soft bricked and that it is possible to fix that although I don´t know why it even broke the OS and Custom Recovery.
Can anyone help me out with a step-for-step-guide to fix the adb Problem and explain me why that blank screen even happenend?
Edit: If I´m in fastboot mode the device is shown as >Android Bootloader Interface< and isn´t listed with 'adb devices'. If it is powered off it is shown as >Android Composite ADB Interface< but is listed with 'adb devices' but I can´t flash the Custom Recovery.

You don't use adb to flash a custom recovery. You use fastboot. That's your first problem.
I actually meant that it isn´t shown with the command 'adb devices' I will change that in the text
Edit: I also noticed that the fastboot mode is always on in the bootloader although the device isn´t connected to the pc. Shouldn´t it only be active if it´s connected?

I see a couple problems here.
First one is use the newest version of TWRP. You can get that from my signature.
Second is Code_Blue may not be compatible with the ROM you are testing.
You don't need ADB at all for this, you need fastboot.
As I said. I just use adb to make sure that my device is found by and connected to the pc. I know that fastboot is used to flash everything but my Nexus 5 isn´t even shown. So how can I get my phone connected to flash the custom recovery?
And it seems like it is compatible since it worked the after the first installation and boot
FFS, XDA. I had just written a huge ass post on how to use fastboot properly, with the proper commands and ****, and you logged me out, making me lose all that. F U.

This is the stock recovery.
You need to put your device in fastboot mode, REFLASH TWRP again with fastboot, then STRAIGHT FROM FASTBOOT select (with vol keys and Power) "Restart recovery". When you're in TWRP, wipe data/factory reset, reflash rom, gapps, REBOOT, PROFIT.
`fastboot devices` and `adb devices` are two commands to check if an active connection exists, between the host interface (on the PC, look at it as servers) and the device interface (look at it as clients). both commands will only return your device's SN IF drivers are correctly installed (speaking on a basic level, and about Windows). If you execute those commands, no SN comes up, then you need to fix drivers FIRST. Not even worth trying to do other commands.
`fastboot devices` only works here -> http://bazalabs.com/wp-content/uploads/2014/07/20140705_215603.jpg
`adb devices` works in TWRP/CWM (NOT in stock recovery) and in Android itself (needs USB Debugging active).
Thanks for the help. I was able to flash the Custom Recovery and the Custom Rom with and without Code Blue Kernel but in both ways the phone loads, sets up at the boot logo and goes straight into the blank black screen which appears without the notification screen of the apps that get optimized.
I can manually turn off, reboot.or take a screenshot which clearly indicates that the Rom itself is installed.
How can I fix that problem?
Thanks in advance
Edit: Tried with the Blue Code Kernel which gave that blank screen and wiped everything but internal storage and reflashed just the Custom Rom which gave me the same result
Could it be because the system.img or boot.img are missing??

Try another ROM.
System.img .. boot.img.. comes with the ROM you flashed (well, not exactly, but both partitions do get written to), so no, they're not missing.
I gave it another try and fixed it.
I'll write it down so anybody who ever faces that problem can solve that, too.
Follow that guide (http://forum.xda-developers.com/google-nexus-5/general/tutorial-how-to-flash-factory-image-t2513701) step by step and after a few minutes of flashing and a few minutes of booting you should get a clean and fresh Android Version on your device. It removes all the old files and installs the newest files.
And thanks guys for helping me out with that adb/fastboot mistake. Kudos to you
Okay, so I had been out of the flashing game for a while now, and recently got a Pixel 128Gb after using my trusty Nexus 6P, and I attempted to do Fastboot boot-to-root.img, which now has me stuck in a weird bootloop issue.
It boots, gives me the stupid can't be checked for corruption ****, gets to the white Google Screen, then there is a weird visual glitch, a blue line appears near the bottom of the screen, then the phone immediately reboots and does it all over again after doing a ramdump.
I can't even get into recovery to manually flash the stock image, as soon as I try to select RECOVERY it jumps to the boot screen where it tells me again that it cant be checked for corruption, and then starts the bootloop all over again.
ADB cant recognize it for whatever reason either. So now I'm probably not your average ****ed, I'm advanced ****ed.
Any body have any ideas?
boot-to-root is for Android O, you have to follow this guide
I had this same exact problem and I was able to fix it by reflashing the factory image. You said adb cannot recognize your device. But what about fastboot? If you reboot into the bootloader, connect to your PC, and execute "fastboot devices", does your device show? Download the latest factory image here. Extract it and execute flash-all.bat. Let me know if this helps.
You don't understand. When you attempt to reboot and go into recovery the manual way, the moment you select Recovery, the phone reboots and attempts to boot up, fails, performs write to ext4 ramdump, then loops over and over. ADB won't work because it wiped with the fastboot oem unlock which wiped the device, meaning no developer mode, which means no usb debugging.
Doesn't matter. Google is sending me a new one.

Fastboot and recovery are two different things. If you hold volume down + power it'll show you the bootloader screen (fastboot), this is where you'd usually select recovery. But if you stay on that screen, you can flash images to your phone. To fix your bootloop, download the boot.img from the stock ROM and use these commands in fastboot:
fastboot flash --slot _a boot boot.img
fastboot flash --slot _b boot boot.img
Then reboot normally.
falsh factory image inside the bootloader, don't need to go to recovery.
Step by Step
Thanks to previous experience with hacking devices (Android, Sony, etc.), patience and only allowing myself to freak out for a few seconds. A couple Google searches lead me to reflashing my Google Pixel 128GB and not sending it back to OEM.
So for the less patient I will break down the steps to do stop the bootlooping.
DON'T PANIC
Either hold down power until your phone turns completely off or wait for the bootlooping to do it for you. It usually only loops a few times before powering down.
Hold Power + Volume Down until it boots into the Fastboot mode.
[This is the screen that says you Phone Stats (serial #, cpu, ram, etc.) and has an Android picture on it laying down.]
Connect your Phone to your computer using a USB 3.0 port.
[My PC wouldn't recognize my phone at all when connected to USB 2.0]
Download from Full Factory Image from Google. { https://developers.google.com/android/images }
[Mine was "7.1.2 (N2G47O, May 2017)" for my Project Fi 128GB Pixel, but make sure you get the one for your phone]
Navigate to where your SDK/Fastboot folder is on your PC
[Unless you moved it, it is usually "C:\Users\USERNAME\AppData\Local\Android\Sdk" by default.]
Unzip the Contents of your Full Factory Image zip file to this location in it's own directory (for cleanliness).
Open a Command Prompt with a Right-Click "Run as Administrator" and navigate you your new zip file's directory.
["\platform-tools\sailfish-n2g47o" or whatever version of the Full Factory Image you used was.]
Type in "flash-all.bat" and wait for your phone to finish its installation. Your phone will restart itself into Fastboot Mode many times during this process.
Once it is finished, you phone should boot into its normal "First Boot Sequence" like you just started it up for the very first time.
At this point you can try flashing something else or use a different technique to update your recovery mode or ROM.
Good Luck.
Hi There!
I'm exeriencing a wierd problem:
On my rooted Doogee S60, i was able to enter the built in recovery mode (and from there the fastboot mode) with Vol+ and Power.
Since i've installed a twrp recovery.img, pressing Vol+ and Power will launch the TWRP UI (wich i cant use, because my touchscreen is disabled).
Normal boot won't work eighter - i flashed a corrupted system.img file as it looks like (ooops). There is also the message at the Boot Screen saying:
"Orange State - Your device has been unlocked and can't be trusted. Your device will boot in 5 seconds"
... although these 5 seconds won't countdown and the device won't boot.
If i enter the TWRP, i can still access the ADB mode. So i can sideload stuff on the device, even the sd card is shown on pc. But the command
adb reboot fastloader
will reboot the phone, but not load the fastloader/fastboot - as it stucks at boot screen (orange state).
Any other ideas to access fastboot, due to flash the recovery.img again with the original to fix?
... or simple question: did i brick it?
thx in advance
Command
Code:
adb reboot fastloader
doesn't exist.

Hi introjoe,
Are you doing? i have the doogee s60 but i just cant root it :'( can you tell me please how did you do it, or the files you use for it? i allready tried but, when i reset and enter fastboot mode, my pc simply dont recognize it.
I want to upgrade the android system to 9 or 10, thats why im doing all o this.
Thanks in advance.
@doryan666
i wasnt able to root the device in the end unfortunately.
i tried using an unofficial twrp, but i was stuck at the main boot screen
i t seems to need some bootloader-activation-code to enter the bootloader to install a new os.
the command line would look like
adb reboot bootloader "CODE"
the activation code has not been released yet by doogee ... and most probably never will be.
sorry to say but i dont think android upgrad will be possible with this device
For some reason, when I go to my fastboot mode, it shows blank screen. Any idea how i can get back to the default fastboot mode screen which usually shows device state, etc. My phone boots up fine , its OEM unlocked but without fastboot im unable to flash custom recovery or rom or do anything to be honest. One plust 6T. Please help

with normal boot, i can access adb commands, its just that fastboot mode is blank and hence unable to access commands. Ive installed all possible drivers, i think the kernel is broken. Any possible way to fix this?

Is developer options and usb debugging enabled in your phones settings? Also no screen lock set? If so if you have another Android device that's also rooted with magisk you can use Osm0sis and Surge's fastboot/adb magisk module, (a quick search in magisk will pull it up) Install it on your other device and use an otg cable ($5 online or make one yourself) and using termux app from "other phone" with connected otg & magisk root type: su (hit enter) grant root once it pops up then type: adb reboot bootloader then tick the pop up on phone you are trying to boot recovery on when it pops up. Then type: fastboot boot twrp_3.4.0-9-11.img (hit enter) Just make sure you put your TWRP recovery.img in correct directory on phone you you're using termux app on with otg and fastboot/adb module to boot the phone you are trying to boot to recovery.
Using root explorer directory in termux is: /data/data/com.termux/files/home/
place your TWRP_3.4.0-9-11.img ,, which ever TWRP image you are trying to boot in that directory...
Hope this makes sense. I don't use Windows and haven't for many years now. I've unlocked bootloader's and rooted many devices using another Android device this way now for years. Super easy! Not sure why you would be getting a black screen. Have you searched for solution to this? I would definitely search , a lot about the black screen situation.. Make sure you have a charged battery too. Sounds stupid I know but it's possible you are at 0%.. Hope this helps...
