The other day my WiFi Xoom stopped getting past the "Motorola Dual Core" screen.
I have removed the SD card.
Android recovery mode gives me the error android with the "!"
It does this plugged in or on battery.
Not rooted.
What else should I try?

Hadn't really done anything. Just normal use. No out of the ordinary installs. Turned it off. Next day I tried turning it on and it won't boot.
Did you ever resolve this ?? I was give one to repair for a child and it too is stuck on the red boot screen. The good thing is the person who sold it to them was a hacker and put TWRP on it of all things. I was floored when I tried to enter recovery and found teamwin.
but the problem is its still stuck on the boot screen, i did flash it 3-4 times with M604 M602 flashes and some other customs but nothing works, it completes flashing and wiping caches but always goes back to stuck on boot screen..
perhaps I have to unclock the bootloader or something for the flash to be succesfull ?
Just wanted to say I fixed it with these commands and firmware if anyone is interested. I tried everything else including flashing with twrp and wiping all caches and it didn't work, getting the stock firmware and doing it like this worked to clear boot screen endless stuck
download fastboot and adb and xoom drivers 6.4 (about 5mb) and the appropriate stock firmware. for me it was ZM604
at the command type
adb reboot bootloader
you may need to unplug and replug cable after it goes in fastboot mode.
fastboot devices
.. should return something "02a439cj0skjdke fastboot" to proceed.
fastboot oem unlock
.. look at your tablet and follow the instructions, for me it was down twice and up once to accept unlock conditions, then it reboots
on reboot press vol down 2 seconds after you see moto logo, it will enter fastboot
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash recovery recovery.img
fastboot flash userdata userdata.img
fastboot erase cache
fastboot erase userdata
fastboot reboot
no need to relock after, you will see android logo and first boot pop up after 2-3 mins
Hi everyone I first want to sincerely thank everyone that will answer to try to help me solve these problems with my nexus.
So the other day my nexus suddenly decided to stop being awesome and it started to be a pain in the ass instead.
When I turn it on it just keeps loading the booting animation of android 6 marshmallowand it never turn on. I identified this problem as a "bootloop" and i tried solving it anyway but it's being really hard and i'm almost getting no results.
I first tried with going into recovery mode. from the fastboot the recovery mode won't start, pops out a died android with a red triangle on it. Pressing volume up and power from that screen got me to another menu. I tried wiping the cache and wipe all the datas/ factory resets but no results. the crappy marshmallow animation goes on till forever.
On the screen that follow the dead android appears the error: E: failed to mount /cache (Invalid argument).
After that i tried with the famous sdk tools.
I am able to unlock the bootloader with the command [fastboot oem unlock]. however after unlocking it, if I turn the phone off and on again it auto lock itself.
i tried to flash a recovery image with the command [fastboot flash recovery recovery.img] but it won't flash. I unlock the device first, and then i try to flash the images. it says ok after the sending but on the writing says FAILED <remote: flash write failure>
same things happen flashing anything else (android factory images etc.)
I can't use adb, i d need to put the usb debugging mode from the developer options but since I coulnd't turn it on I don't know how to turn this option on.
So i discovered existed a "download mode"
Apparently for the nexus5 you have to push volume up and then connect it to the usb to enter in it. I tried many times and it just don't go to download mode (is this the correct procedure??)
I installed the last google divers, no results.
I really don't know what to do, do you guys have any ideas about how to save it?
phone details:
hammerhead d821(E) 32GB
hw version- rev 11
bootloader version: hhz12k
Cheers
Mattia
I think your emmc chip has gone bad and that is why you are getting locked bootloader everytime you reboot the phone as it is not able to hold any memory.
I suggest RMA if its in warranty

OK so ur ennc chip is NOT dead, that little Android with the triangle is stock recovery, which u can do nothing with, ur going to need a PC, preferably running ubuntu or some other form of Linux with adb and fastboot installed, i cam help with that too if u need it, once u get that settled what u need to do is this, download TWRP for ur hammerhead and rename it recovery.img, place it in a folder u have access to. Open a terminal and connect ur nexus to the pc with USB cable, and boot into bootloader. Then type this into the terminal:
cd (folder with recovery.img in it)
fastboot reboot bootloader (this should boot u back into bootloader if ur device is connected right)
fastboot flash recovery recovery.img
fastboot reboot recovery
This will boot u to TWRP in which u can perform a factory reset, if this doesn't work and ur still in a bootloop, download ur fav rom and gaps and flash it, this will take care of everything
And there is no download mode on the nexus that would be bootloader mode, so let me get this right, what system are u on, and did u try manually formatting with ADB? What happens when u do, I would force format cache, system, boot, and userdata and then flash recovery, that might work

I tried to flash stock kdz with LG Flash Tool 2 days ago and process was stopped in the middle of flashing so I had to exit program and to pull my battery off. And then when I tried to turn phone on again it wouldn't boot but it showed only something about fastboot and when I'm trying to flash something with it I get unknown error.
This is what it says on screen:
fastboot int()
loading keystore failed status 5
Usb init ept @ 0x....
udc_start()
--reset---
--portchange---
fastboot: processing commands
Phone wasn't rooted and bootloader was locked, I can't access download mode anymore, neither anything else cause no matter what combination of keys I use it only boot into this.
So what are my options for this?
Hello everyone,
after unlocking my bootloader (on a Realme 5 Pro) to install TWRP and custom ROM, I am now stuck at trying to make fastboot do anything.
No matter which fastboot command I try, the phone won't execute it. I instantly get a "FAILED" and "(No error)" returned and the phone exits fastboot, showing some logo with a chinese message, as well as "press any key to shutdown" in the top left corner.
The only excpetions to that behaviour:
1. "fastboot devices" works as expected and recognizes the phone.
2. "fastboot boot [path to TWRP .img file]" sometimes gets stuck at "downloading boot.img..." indefinitely, sometimes it fails like all the other commands
3. "fastboot flash recovery [path to TWRP .img file]" gives an instant "FAILED", but the error message is "requested download size is more than max allowed"
I've tried re-locking and unlocking the bootloader, when unlocked both colorOS and fastboot recognize the bootloader as being unlocked.
I have no clue what to try at this point, hopefully someone can help me out?
Same problem here.
Mine is Realme 3 pro with the new version of realme UI, RMX1851, C.04, I have unlocked bootloader without downgrading it to color os 6, but now I cannot flash twrp in my device. After going into fastboot mode, after applying the commands, it says "FAILED" (remote: GetVar variable not found) and sometimes directly "ERROR"
The fix was an incredibly easy one, but I only found it/got the idea through a lot of googling... simply used a different PC (that I never used adb and fastboot with before), let windows search for drivers online, and BAM, it works!
Hopefully this will help someone in the future.
If you don't have more than one PC, I guess the best bet would be uninstalling all adb and fastboot related drivers.
Hi everyone.
I´ve decided today that I want to re-lock my bootloader on Lenovo P11 tablet and I discovered no fastboot commands work on that.
I installed clean version of ROM from Lenovo Rescue and Smart Assistant (TB_J606L_S120217_210805_ROW) but still nothing works.
Normally i reboot to Fastboot and try "fastboot flashing lock" but i recieve:
< waiting for any device >
FAILED (remote: 'Unrecognized command flashing lock')
fastboot: error: Command failed
When i try others like "fastboot oem lock" i recieve:
FAILED (remote: 'Command not supported in default implementation')
fastboot: error: Command failed
Does anyone has any advice what can I do to relock bootloader?
1. enable developer option
2. enable oem unlock in developer option
3. boot to fastboot mode and run
fastboot flashing lock
Thanks @ong14 for your reply but as you can see above I already tried that...
If you're on chinese firmware, try "fastboot oem unlock-go".
Sadly I get this response for this command:
FAILED (remote: 'Command not supported in default implementation')
fastboot: error: Command failed
Is it possibly because of version of my ADB and Fastboot tools? I downloaded many versions (lastly directly from Android Studio) but it didn´t fix anything. @ong14, could you possibly upload the tools you are using?
Sorry for my last reply, it should be "fastboot oem lock-go".
AFAIK, if you're on global rom, use this "fastboot flashing lock".
And if you're on chinese rom, use this "fastboot oem lock-go"
I'm using an old minimal adb and fastboot.
It is totally OK, I am grateful that you are trying to help me at all.
I will try your old adb and fastboot tools and see what happens.
Sadly I don´t have much hope. I am on global rom and command "fastboot flashing lock" resulted only in:
"
FAILED (remote: 'Unrecognized command flashing lock')
fastboot: error: Command failed
"
I will keep you posted about my progress and what else I tried.
Well, sadly, still nothing. I tried everything I could think of. I even tried different PC, flash rom with QFIL even with stock bootloader. I still get the same response.
Did anyone else run into this problem?
Edit: After further investigation it seems that I shouldn´t be in the fastboot mode but in the bootloader mode. There i should try "fastboot flashing lock".
Sadly, I see my P11 in device manager only as unrecognized Android device and no drivers seem to change that. Tablet also isn´t visible in the "adb devices" or the "fastboot devices"
Does anyone pls have working drivers or should I continue trying fastboot mode?
Edit2: OMG, I finally solved it. Yes, i shouild be trying to lock the bootloader from the bootloader mode from the start. After I booted to bootloader mode, installed Lenovo USB drivers (https://www.mediafire.com/file/1bzfblquyofokgi/LenovoUsbDriver_v1.1.34.zip/file) and it finally worked!

My guy, you are brilliant. I wonder why the change from oem to flashing was done and were you getting sent to that fastbootd menu too? This worked for my 2020 Moto Edge and I don't know how much longer I would have needed without you.
Thanks.

Install RSA from Lenovo also works, and you can run rescue if you want to go back to 100% bone stock

Where and how do you get the drivers for this tablet? For some reason I'm stuck in (what I think) is the exact same screen on my tablet. It says fastboot... in the lower left hand corner and you can hear the disconnect chime come from my laptop every few seconds. I punch in fastboot devices and it's stuck in limbo, no error codes or anything.

Did you check device manager?
I didn't think I had to, when I plug in the tablet it pops up with the name and everything.
I'll try the Motorola drivers, is that going to solve the fastboot stuck screen?
Where do I go about getting the Motorola drivers?
hey mate. i had problem. now my Xiaoxin Tablet Pro 2021 having widevine L3 even i already lock the BootLoader and Stock Rom. how do i get Widevine L1 ?
