[Q] Xoom won't boot

So I'm trying to fix a Xoom for a client. Her nephew was using it over Thanksgiving weekend and has managed to mess it up.
1) On a normal boot it never gets past the boot animation. The animation just loops and loops.
2) I was able to get into recovery and do a factory reset, but that didn't improve anything.
3) I can get to "Starting Fastboot protocol support" or "Starting RSD protocol support 0"
4) I have used two different moto drivers on Win 7 and Win 8, but neither computer ever recognizes the xoom is connected regardless of mode
5) Adb never sees the xoom either.
6) This device should have been completely stock, but no one knows what this kid did with this tablet.
7) USB debugging was probably off since the owner would not have known about it or had a reason to turn it on.
What are my options here? I'm thinking that I need to flash a good factory image, but I need to get some communication going first.
Update: I've been trying different cables. I found one where the computers will see that a devices is connected, but am getting "USB device not recognized" with either set of drivers that I have on both computers. Making progress, but could still use some help.

I had a problem similar to that about a year ago, somewhere in these forums was the suggestion to remove the SD card and then do a factory reset, it worked for me. My xoom just stopped working, I thought at first it was a flat battery but after charging the symptoms were the same as yours, might be worth searching through the forums if you haven't already

There's no sd card in it, just the little plastic place holder. I've been looking all over the forums, but I normally deal with Samsungs. I've been figuring out Motorola's little quirks as I go along. Is there a recommended moto driver for these things?

Sorry can't help , mine is just over 2 years old and except for that one problem have never had any issues so have never needed to even connect it to a PC

I recently discovered these handy files when I needed to return to stock:
4G Xoom (MZ600) Restore
3G Xoom (MZ601/3) Restore
WiFi Xoom (MZ604) Restore
If you need to find out which Xoom model it is, power on whilst holding the volume down button, this will take you in to fastboot. Then (you sound like you'd know how do this, PM me if you don't) use "fastboot getvar all". This will return the model.
Unzip the file above, there's a batch file in there which will install the drivers, then fastboot the firmware over.
If you boot to fastboot, then run the batch file, it installs the drivers, then "adb device", then it asks if your device is connected - it won't show up cos it's in fastboot. Just ignore that and say yes, and it'll start flashing the files.
Sorry if I'm too late - don't visit these boards much these days. Good luck, let me know if this works.

Thanks for giving me something to try. I uninstalled the moto drivers I had and installed the ones included in the zip file and restarted my computers. The Windows 8 computer never recognizes that the xoom is connected in any mode. The 7 machine does see it in fastboot mode but as a "fastboot" device for which it fails to find drivers. When I run fastboot getvar all, all I get is <waiting for device>.
I do know that this is a wifi only (mz604) xoom. Thanks for the image files. If I can get this stupid thing to communicate with a computer, I think I'll be in business.

In fastboot mode (vol -) it won't acknowledge that it's connected. Just fastboot your image over and it will work.

If I try to do anything with fastboot, it just says "< waiting for device >". Fastboot doesn't see a device to flash to.

OK, it's either your cable or your driver. Many cables are for charging only, and have no data lines. I throw those away.
As to drivers, I'm Debian for 15 years so can't advise on Winduhs.
Oh, one more thing: I've noticed that on my old HP laptop I had to use a certain USB port, or else it wouldn't comm with my phone for fundamental actions like loading new firmware.

These were the drivers I used: https://motorola-global-portal.cust...sion/L3RpbWUvMTM4NjM1MjA0NC9zaWQvWEo3SWU5SGw=
They don't seem to be windows 8 certified though.

We finally got it. We used DriverEasy to look for drivers because we have a bunch of extra licenses and the drivers we had obviously weren't working. DriverEasy was able to install an "Android Bootloader" driver that must not be part of the SDK. Once that was installed, I was able to use fastboot to flash the images from above. The device is in good working order again and fully updated.
Thanks for all your help.

Always nice to hit the Thanks button for those who've helped.

HTC One Mini (M4_U4) Softbricked, OEM not unlocked, USB debug not enabled, bootloop

Hi all,
My HTC One Mini crashed one month after warranty (Boo!). I can get to the FASTBOOT and BOOTLOADER screen and select options. However, the Factory reset and recovery just cause a vibration and get be back to FASTBOOT menu. The phone is *** LOCKED ***.
After a few false starts on linux and mac machines, I've installed WinDroid Toolkit v3.1 on Windows 7. I have gotten the Token ID and used it to get an Unlock_code.bin via email from the HTC developers website (Cannot link as newb). However, when I follow the instructions in WinDroid it recommends that newer devices require "Enable OEM Unlock" to be set:
I cannot do this now. I continue but when it says a menu will appear on the phone, the menu does not and the phone remains in *** LOCKED *** state. I tried continuing with step 2 "Flashing a TWRP" but it does nothing.
TL;DR Am I screwed with having previously unlocked OEM on my HTC One Mini, now that it is soft-bricked?

I'm not that good at this stuff, but managed to get mine unlocked and a recovery on it via this link
sadly mine still has a problem in that it's now stuck in a boot loop, so don't use Oneclickroot as I did in my post here
hopefully you will get yours to work ok, but when you get to instruction 17 you may find that HTC website is quite fussy with the code you copy/paste
when you copy the Identifier block into Notepad or whatever, ensure you don't get any leading blank spaces before you submit it to HTC.
this excerpt from mine had blank spaces where I have inserted red X's, but it worked with them removed and HTC then emailed me the Unlock_code.bin file

sorry,
lost the plot on my first reply and forget about the OEM unlock bit ...
to get that OEM unlock bit you would normally
first Enable Developer Modeon your phone by Launching the Settings Application -
Scroll Down and Tap on About Phone(or About Device) - Locate the Build Number Section - Tap on the Build Number Option 7 Times -
Go Back to the Main Settings Page - Scroll Down and Tap on Developer Options and it's found there
but given that you are in is bad a place as me in that we cannot get a bootup, I'm afraid I can't offer any more info,
but it's worth knowing anyway in case you do get booted up

Hi, i have the same issue, but a little different.
My phone was in a box for like 2 months, and then i decide to turn it on again, and i faced the same problem as the OP, but my One Mini is UNLOCKED, and i can't lock it again because i get an error in ADB. I try to enter on recovery (and flashed three differents recoveries without sucess), and reboot in bootloader, then try to factory reset, and reboot bootloader again. It don't do anything, only turn on when i plug the usb and enter in bootloader but no more than that. i've try to flash a RUU too, but it give me the error 171. i tried too the method with the rubber band pressing the power button to cause a reboot loop and get enough charge to launch the system but nothing, i don't see any results. I'm one step closer to give up, please help, i tried everything and nothing has worked for me. If need more information don't doubt on asking me. I really appreciate any help you can provide.

I'll try mate ... but perhaps you are asking for help from the wrong guy! - firstly I have to say mine is still in a very bad place! -
I managed to get a permanent TWRP on it, installed a lovely rom named InsertCoin on it, rebooted, and all seemed fine, but then the battery drained rapidly and it would not charge - that issue is ongoing and I'm spending ages on it just now..
Firstly can you confirm that you can enter Bootloader and select Fastboot, and that your phone is then recognised by your PC?
ie: let me know what happens when you press power and vol down together, select fasboot, goto PC, run ADB, cable phone to PC,
then issue the command ADB devices
can you also upload a photo of your bootloader screen

i don't need to press vol down and power together, the phone enter in bootloader once you plug the usb cable. it do that alone.
This is what i get
C:\adb>adb devices
List of devices attached
C:\adb>
the phone is recognized by HTC Sync manager but i can't see it in ADB.

a few things things jump out at me ...
1. from your photo the screen is shattered! - even though I don't like being beaten by phones I would scrap it
the repair would cost more than you can get one from ebay for - about £40.00
2. "abd devices" should return you something like ... "List of devices attached sh3d7h3dj631f6a7" - when it doesn't it show a device number it's usually your drivers
3. you may think that's not it since you say that it is recognised by HTC Sync when on your PC, but I had read that HTC sync is unreliable and that the drivers are not the best
the one's I used were HTC-Mobile-USB Driver-v4.17.0.001.exe but I can't remember where I got them and will upload them later today and send you a link.
(also, it pays to plug your usb cable into a rear port on your PC when doing this kind of work as front are not as reliable)
4. your Hboot is shown as 2.22 -this also can be a problem for TWRP see this link
5. the download link he has is broken, so get any TWRP above 2.7 from their website here

2. I will leave you down here exactly what i get when i type "adb devices" (with an attached image)
3. i have installed the latest HTC drivers, and i tried connecting my phone to front an rear usb ports, both of them. No results.
4. Down here i'll leave you an attached image of what i get when i try to install a recovery by typing "fastboot flash recovery recovery.img" (i changed the name to recovery.img of course) and the phone seems installing the recovery in fastboot but it gave me that error in adb and when i try to enter in recovery it reboots on bootloader.

your first image does not 'see' your device mate, so there is no point in trying a flash of anything
until you get a response from "adb devices" that shows a device number you have no chance of getting anywhere!
I am quite certain that the problem MUST be with your drivers
my advice would be to uninstall the HTC Sync and clean out any drivers on your PC and to install the drivers and flash the TWRP I mentioned earlier
sorry I didn't upload earlier as I've been very busy indeed - they are now on my Google Drive ... links here .... and here

Hello guys, I've been following this thread and I'm having same issue. Adb does not sees my phone.
Fastboot does, but when I run ruu , it disconnects and give error 171
Tried usb 2 instead of 3.nothing.
I also think it's the drivers, but I can't seem to find the correct one for this phone. Any help is appreciated

my phone only starts in bootloader it have s-on and i cant use the toolkit cause usb debugging isnt active
adb writes waiting for device
can anyone help me?

Lost TWRP and ADB/Fastboot can't see phone to sideload. What can I do?

Basically what happened was:
After updating PureNexus on my Pixel XL, I flashed the vendor image to only one slot
Booted system to find endless crash dialogs
Rebooted into recovery to find TWRP gone
Did a Full Wipe under stock recovery, hoping it'd fix things
I can now get back into system, but it's glitchy
Neither adb devices nor fastboot devices see the phone
Troubleshooting I've tried:
Plugged usb-c thumb drive into phone. It works fine, so it can't be the port
Plugged old Nexus 5X into computer. ADB and FB can see it just fine, so it can't be the cable or drivers
Plugged Pixel XL into computer. Phone charges but pulldown notification doesn't appear
I don't know what else to do. Prior to this, I was always able to see my Pixel from ADB/FB. I don't know why it's not working now. I would've thought that a "fastboot devices" from bootloader would at least work, and yet it's not. I can get into stock recovery just fine, but there don't seem to be any helpful options there.
Does anyone know what's going on or any way to remedy the situation?
NOTE: I'm on a Mac

It can be the drivers, Windows isn't going to use the same drivers as the Nexus, unless you manually select them in device manager.

But I never had a problem with the drivers before now. I've always been able to ADB my Pixel, which is how I rooted and installed TWRP originally.

Is it through the Android Studio SDK manager? I remember using that way back when to get everything set up, but I haven't really used it since then.

Actually I just remembered that Mac don't need drivers, right? Per Google:
"Note: If you're developing on Mac OS X or Linux, then you do not need to install a USB driver. Instead see Using Hardware Devices."

Update: Pulled out my Windows laptop and installed everything (drivers, Android Studio, et al) to see if I'd have better luck there.
To test, I first plugged in my working Nexus 5X. Windows immediately recognized it. Pulled up a prompt and adb devices saw the phone no problem.
Unplugged the Nexus and plugged in my Pixel XL. Nothing. No "hardware plugged in" chime, nothing listed under Device Manager, nada. Likewise, the phone itself doesn't acknowledge that it's been plugged in because there's no Android System pulldown.
If it were a driver issue, Device Manager would still at least be able to see the phone (it just wouldn't know what it was). But I'm getting absolutely nothing.
I can only assume that the problem is indeed with the phone itself. I don't know what the problem is exactly, but I know it wasn't there before all of this. Either way, this means my only hope for a fix would have to be through the phone itself. But since Stock Recovery doesn't seem to offer me many options, I have no clue what to do next.
Is there some sort of "secret" key combo or command or something that'll do a low-level format of the phone or something? I'm grasping at straws here, I know, but I honestly don't know what else there is I can do.
-------
Update 2: If I plug it in while in Bootloader, Windows recognizes that a device was connected, but as an "Unknown USB Device (Device Descriptor Request Failed)"
None of the solutions I can think of (or Google) seems to work. Has anyone heard of this problem before? I'm vainly hoping there's a fix out there that I just haven't found yet.

Oneplus 6 unable to be unbricked

Hi everyone,
A couple of days ago I rooted my Op6 and then decide to flash No limits rom via recovery (blu spark), as I was used to do with my last android phone, the Samsung Galaxy Note II.
Unfortunately I missed something and now it is stuck in the bootloader screen. Nothing works from the phone and I couldn’t revive it. I use a Mac but I tried all tools that are adviced here on XDA with my friend’s Sony Vaio but without success.
I managed to update drivers but I cannot run a flash-all.bat and I cannot use MSMdownload tool.
How can I do? Thanks to anyone who will manage to help me!!

EDIT: Sorry, just noticed you say you cant use the MSM tool. This one worked for me.
You could try this
https://forum.xda-developers.com/oneplus-6/how-to/tool-msmdownloadtool-v4-0-international-t3903272
Worked for me.

Check the guide about unbricking and if You are unable to use flash-all.bat so you Have to flash commands One by One. It's worked for me a few of months ago.

It doesn’t work either that way. I updated my drivers, but no computer is recognizing the phone.
I tried from changing usb cable or port to changing computer, to change methods.
I didn’t found any solution here on XDA, I tried everything!!

Make sure u use the cable included with the phone. Some cables doesn't work

Neither. I tried with the original and two others that I have.

if possible do you have windows? the flash-all.bat works for windows and is better to use(i was unable to use it normally in linux). What happens when you show flash.bat?

I tried Mac and Windows. On Windows it always shows in terminal "waiting for any device", even if I uploaded the drivers and made everything possible.

Did you put your OP6 into fastboot mode in correct way? I mean you might be doing the wrong procedure when entering fastboot mode.
It happened to me for the first time, I came from Samsung and I thought the phone needs to be stayed on the fastboot menu screen just like Samsung but no.
You need to turn it off and reboot it while pressing home and vol down button simultaneously until the PC recognize.
Good luck unbricking~

I always powered it on via power+volume up before connecting to the usb cable, because connecting it while powered off always resulted to power it on automatically on bootloader screen

Botched Graphene install on Pixel 3A - need help restoring default settings

Hello,
I am hoping for some advice on how to revert my phone back to its original "factory settings" after a botched instal of GrapheneOS onto an unlocked Google Pixel 3A.
I got to the point at which I needed to Flash the Graphene Rom to the phone, but rather than installing, I received a message from Smart Screen MS edge asking if I really wanted to run as it's protecting my PC - I clicked run anyway and a blank command line window appeared for a second. Now my pc doesn't seem to be recognising the pixel 3A when I type ADB devices. My phone is currently in Fastboot mode "unlocked" and I'm hoping for some advice on what to do next. I'm total noob, so unsure how to start the process over (return the phone to it's previous state) before, maybe, trying again on a different PC.
I have since turned on my phone and Android 11 is still present and seems to work fine (however it gives me a warning on startup that the bootloader is unlocked.
Any help would be very much appreciated - thank you in advance.

Is all what happened that your phone now:
complains about "'maybe not safe bootloader unlocked".
This is just what android does when the bootloader is unlocked.
This you did before trying the flash.
If you want the warning gone simply lock it again.
However if you into the market for graphene OS then I would recomend: along with following their guide to a t to also read up here on xda about the general rooting unlocking thing a bit more so you get the overall process a bit better perhaps next time.
About windows. There are so many tools out there to help ya with disabling some of it's spying, turning off smartscreen, auto - uploads of all your data to M$oft, etc etc.
It's not hard to find.

Thanks for the response - I think I've worked out what is going on.
Typing ADB devices, my PC recognises the phone until I put it into fastboot mode - typing adb devices when in fastboot comes back with nothing and therefore when I try to flash, I assume the devices aren't talking to each other.
Not sure if there's a work around or whether it's a case of finding a new PC to try it on?
Thanks again.

try another USB port first; use USB 2.0 if available! Reinstall google ADB drivers, make sure to use latest!
If above will not help:
on your computer: open device manager; on your phone: put your phone into fastboot; connect your phone to the computer WHILE keeping an eye on device manager; as soon as you'll connect your phone new device will appear in device manager ("unknown device" most likely but it might be some "android device" or "ADB device" too); right click it —> update driver —> automatic driver update worked in most cases for me, if not, go manual way and select google's "android fastboot device" (or something like that, can't remember actual name of the device); after driver install confirmation you should be good to go

Hey there,
This is brilliant - thanks for all the advice. Having this support is helping me gain the confidence to learn more, research more, and then give it a go.
All the best.

thats if I am not wrongly remembering my experience:
because now your phone is in fastboot mode thus it won't show up with that command anymore.
Try: 'fastboot devices'
I imagine you put it into fastboot through: 'reboot fastboot' when you where in adb?
When in fastboot you can go on and flash the recovery and such.
Are you still in need of help here?

Hey, thanks for the clarification - been away and so haven't implemented all suggestions, yet.
I typed "adb reboot booloader" which I assumed put it into fastboot mode and then unlocked it using "fastboot flashing unlock".
I tried fastboot devices but the PC still doesn't see the phone. I'm going to try the update usb driver suggested by Tamsta_T and see how it goes.
Thanks for your help.
