Xoom 4g Stuck at Red M

My Xoom is a 3g that I sent in to have the 4g upgrade. Ive been running different roms for a couple years, decided to go back to stock the other day. I followed some steps I found at xda about how to do that, It was some version of honeycomb.
Anyways, after a reboot of the xoom It is stuck at the red M. I cannot get into recovery, cannon use adb commands. However, fastboot is working. What can I try next? After spending hours googling it, this doesnt seem real uncommon. But most of the links on how to put on a new bootloader with something called avalance 1.35 seem to be broke. Any ideas?

Your Xoom does not have an OS installed, nor a recovery.
Need to fastboot the stock images.

Correct. However, I cannot get into recovery to flash a rom. I have tried pushing the Motorola default through fastboot. It says it takes it but doesnt do anything.

I have done the following:
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash recovery recovery.img
fastboot flash userdata userdata.img
fastboot erase cache
I got the files from the Motorola Support site.
I also used the RSD Lite to try and push factory image.

are you using the correct stock images for the 4G version?

Here are the links I have tried:
http://www.randomphantasmagoria.com/firmware/xoom/trygon4g/
HLK75D
I also tried the motorola image: MZ602_HLK75D that I had to request from Motorola.

It seems that what you have tried is the correct process. I too have the 4G Xoom (USA) and have used that process myself many times. However I used the "MZ600_HRI66" images, to return to stock with no problems. I may suggest to repeat the return to stock process using the HRI66 images.

WIll try, thank you. Ever heard of everest 1.5 bootloader? It looks like that may be a common fix. All the links I find are broken.

Nope.... flashing HRI66 didnt change anything. Still cannot ADB, still doesnt boot.

no never heard of it. are you on everest?
adb wont work unless usb debugging is enabled, and you can't get into
USB debugging because you can't get into the system.
try this to place a recovery;
fastboot oem unlock
fastboot reboot
Get back into fastboot then grab a recovery image;
fastboot flash recovery (your recovery.img here)
if all else fails - go here - http://forum.xda-developers.com/showthread.php?t=1468298

Recovery failing to flash

So I flash the stock rom on it without thinking and now it wont let me flash a recovery to the tablet threw fastboot or goomanager and it wont update throguh asus update but its booting fine and wont take any updates at all i need help being pointed in the right direction!

I flashed the wrong bootloader i think and how do i flash the correct bootloader without a recover?

in fastboot im getting the error: cannot load 'file name' :no error weather its cm or twrp it wont load it and i dont know what to do please help

First of all it would be important to know what bootloader you are actually on. You do not want to flash a recovery that is not compatible with your bootloader!
So boot into the bootloader with Volume Down and POWER and read the tiny script. From there select the Android with Volume Down and boot back to system with Volume Up.
And then please report in detail what you are trying to do in fastboot, which commands you use etc.
Without knowing what you are doing we cannot tell you what you are doing wrong.....
First step: In fastboot command: fastboot devices - Do you see the serial number of your tab?

So you are on an ICS bootloader with a JB rom... How the hell did you manage to do that?
You did not answer my question about fastboot. What you tried and what did not work.
But anyway, how I would proceed, just to get you back into safe territory, is to download the latest Asus firmware 10.6.1.14.10, unzip the downloaded file once and copy the resulting zip to the root of your internal SD.
Reboot, and hopefully the stock recovery will recognize the update file and flash you to JB 4.2.1 (which BTW is the latest version for our tabs - there never was, and probably never will be a 4.2.2). Flashing the stock firmware will replace the bootloader.
So from there you just have to get fastboot working, flash the latest TWRP and then the custom rom of your choice COMPATIBLE with your bootloader and recovery.
If that doesn't work we have to try something else. But try this first and report.

Can't boot into recovery. any idea if this can be fixed?

I tried to root my Opo, but it started to go wrong after i flashed it. It went to reboot into TWRP, but all that happened was it crashed. the 1+ logo comes on and then the screen goes blank. This Happens all the time when I try a "fastboot oem unlock", factory reset, or a boot recovery.. the fastboot does work, but the device is also locked and i can't do a recovery due to this. I tried to do the root tutorial on youtube by C4ETech.. help please!

@nickizm, when you boot to fastboot and enter the command "fastboot devices", can you see your device listed on the screen?

Thanks for the reply.. The fastboot work fines apart from when I try to unlock the devices and it reboots into recovery, it crashes and doesn't unlock.. the rest of the phone works fine apart from the recovery... my bootloader is also locked and I can't unlock it due to crashing
(bootloader) Device tampered: true
(bootloader) Device unlocked: false
(bootloader) Charger screem enabled: false

I can't be certain but I'm pretty sure I read a similar issue to this a few days ago that was caused by not having the latest fastboot software, the user resolved it by downloading the latest android sdk and trying again.
Worth a shot.
Hope it helps.

I had trouble when I first tried to root. Twrp wouldn't install. I ran some command which loaded it up but didn't install it on the phone, I was the able to root my phone.
Make sure you have latest oneplus one drivers. Have you tried using oneplus one toolkit to install recovery?
Sent from my Oneplus One using XDA Free mobile app.

I've tried to install a recovery, but my device is locked. If i do a "fastboot oem unlock" is just crashes on me when it going into recovery. I also get the same crash when I do a factory data reset or if I reboot into recovery. I think it's definitely something to do with the recovery, but since my device is locked i'm not sure what to do?... cheers again

I'm sure I did.. It wasn't that old.. I can try again, but the problem is I won't be able to unlock my phone??
is this the right link? http://developer.android.com/sdk/installing/index.html?pkg=studio

New drivers, exactly the same

Have you tried using a toolkit to do the unlock for you? People usually advise against using toolkits to do it for you as it prevents you gaining the experience of doing it yourself, but since it's not working when doing it yourself I don't see any harm in trying a toolkit.
You can find several options at the bottom of @timmaaa's resources roll-up thread here

Yea i have also tried the tool kit V2
My problem is that the recovery is damaged in some way and my device is locked. i can't "fastboot oem unlock" as it just crashes when it goes to reboot.. is there a way to unlock my device with another method or can the recovery be repaired some how? i'm such noob

I think you might be out of luck, unless someone here more knowledgeable than I can help.
If you have a recovery image (not zip) you can try running the following command (make sure the img file is in the same directory as your adb/fastboot files and rename it "recovery");
Code:
fastboot boot recovery.img
What this allows you to do is boot into the TWRP recovery without having it installed on your phone, but I think I read somewhere that this command no longer works.
EDIT: If the above command will let you boot into TWRP, you'll want to read the guide here and flash the script.

One last effort, after a bit of reading I've seen a few people with your issue have resolved it by flashing ColorOS (Chinese Stock ROM) and then going back to a custom rom once everything is fixed.

can you give a little detail about
"device is also locked and i can't do a recovery due to this"
you did fastboot oem unlock. so saved data is wiped. but you should be able to boot into android system,
if so, enable "developer options" by clicking "settings" --> "about phone" --> "Build Number" click it 7 times,
then go into settings developer options and enable USB debugging.
then, use not fastboot, but adb to boot into recovery.
adb reboot recovery

That doesn't work as my device crashes when it goes into recovery..
eg: "fastboot oem unlock", factory reset, or a boot recovery all crash as my recovery isn't working. When my device goes to reboot in recovery the 1+ logo comes up, fades out to like a blueish from the white 1+ logo and crashes.. so basically it's looked and I can't get into recovery.. thanks for trying

Trying to flash TRWP Moto Z recovery - not working

Hey everyone, longtime lurker here finally going to try to get involved more since I just got a new Moto Z and I don't have much of a background with motorola hardware/software. I'm trying to flash recoveries through fastboot and I can't seem to get it working. I'm probably going to wait a while before I try again since there is not much support for the moto z yet. I am running MPL24.246-45 v6.0.1 XT1650-03, I have unlocked the bootloader through the instructions on the motorola website.
On the bootloader screen I can confirm it is now unlocked, but everytime I flash the TRWP recovery through fastboot I get the error message: "<bootloader> img not working or corrupt". I am trying to flash the most recent twrp recoveries for moto Z (twrp-3.0.2-0-griffin.img) but wasn't able to successfully flash it.
Coming from a samsung background, I might be skipping a step or doing something wrong. I am running the bell canadian firmware. Since I messed up my partitions on my last phone I want to be careful with this one, I mostly want to figure out why I am getting this error while trying to flash the recovery when
my bootloader is unlocked and when I check "adb devices" my moto is being read.
Thanks!!

I've tried both with the original twrp name and extension as well as with renaming it to recovery.img, didn't seem to make a difference. If I am connection to the device itself does that mean that adb/sideload is installed properly? I mean I was able to unlocked the bootloader so I would assume so.

i really don't know then.. if you successfully unlocked bootloader then fastboot should be ok. you can check in device manager. it should be bootloader iterface not adb interface there (you got me confused with mentioning adb so I am just writing to be sure).
also check if your device is shown when typing
Code:
fastboot devices
or try redownloading twrp.
otherwise I am out of ideas, sorry.

Sorry for my confusion with adb/sideload - from what I understand I need both to be able to connect to my device (correct me if im wrong). In the bootloader menu I see "flashing_unlocked" which I believe confirms my bootloader being unlocked, but then at the top of the text right under the dead android guy I see "AP Fastboot Flash Mode (Secure)" could that be an issue?
I can retry downloading the recovery from the TWRP site, but I know I'm downloading the official one already, just can't put my finger on why I'm getting that error message if others are doing it successfully.
thanks for helping :good:

You're at the bootloader, it says Flashing Unlock so yes your bootloader is unlocked and you should be able to flash TWRP no problem.
Did you recently install this .45 firmware? Are you sure that TWRP wasnt actually flashed? I see lots of errors like this from the bootloader and its usually just rubbish.

The twrp does not show the actual memory value of my cell phone and does not let me paste ROM backup, from insufficient memory? how to support it?

I updated my phone to .45 when I bought the phone I believe 1-2 weeks ago, it's definitely NOT flashed as the flashing process runs for 0.2 seconds and fails. I can even boot in the stock recovery afterwards confirming that nothing flashed. I wish I knew what I was doing wrong? possibility of drivers not installed properly?
Before I try and flash recovery I check USB debugging, OEM is unlocked, don't verify ADB files and accept Unknown sources. Is there anything I'm missing?

edit: I've read on different articles that people sometimes try and flash from the recovery menu? I understood it has to be while your are on the bootloader screen, could it be something to do with that? Or is it still a possibility the drivers may not be installed properly.

With fastboot boot you send recovery to your phone and ask it to boot on it without really flashing it...
It's useful e.g. to take a full stock backup including original recovery, to test a recovery prior to flash it or to use TWRP to root BUT remain on stock recovery...
Not on all phones it works, but on Moto Z should....
P.S.: you have to be on fastboot screen not on recovery when flashing...

Right, bootloader screen. Enter on it by key-comb... not by command...
Even the real flash take same time... Sending seems to work, is something on verify that doesn't "like" it...
Try to download again recovery and/or check its MD5...

if reading correctly (and what I told you yesterday) command is
fastboot flash recovery recovery.img
and not
fastboot flash recovery.img

i don't know from which ROM you are coming, don't know if downgrading works, but this was onl RETEU ROM i could find.

I have the exact same phone and I've upgraded to Nougat but I got my TWRP working. You need an unlocked bootloader and after upgrading to nougat, the option "unlock OEM" need to be enabled again.
I've used this TWRP : https://dl.twrp.me/griffin/twrp-3.0.2-0-griffin.img.html
Also I tried to only boot on it at first with the command fastboot boot twrp.img then I saw it was working, I flashed it with fastboot flash recovery twrp.img but got the error : (bootloader) image not signed or corrupt . But I booted the recovery from the bootloader and TWRP was working even with this error.

Upon reboot after flashing it now just goes into the download mode where i have the option to reboot bootloader go into recovery and go into download mode. Normally not a big issue at all but this time when i go to load into recovery or load into Download mode its says Operation Denied. Upon a reboot or trying to reboot into safe mode it says ERROR: Slot unbootable: Load Error. Will ADB still work to flash this? not really sure what to do at this moment.
EDIT: Solved it by using Fastboot and flashing the stock firmware without the -w so far everything is back to normal....know to get that dern kernel again

First off, does fastboot recognize the device?

It does not under adb devices nothing shows up. In device manager it does show up as Android bootloader interface

ADB=system. Fastboot=boot. You can't boot your phone, so you're not in android, thus no ADB devices. Type "fastboot devices" and see if it's recognized.

Good news! So, your best bet at this point would be to re-flash your current factory image, with /w removed. If you still want that same kernel, flash it before Magisk.
Just out of curiosity, what method did you use to flash it in the first place?

It wipes all your data, that's why you remove it from the flash-all.bat script, unless you need to perform a full wipe. Telperion has an excellent guide for installing the lastest software, if you haven't already read it.
I've heard users having back luck flashing kernels in TWRP, as the kernel has something to do with recovery. I always use the method of booting the TWRP image in fastboot, use ADB to push the files to /tmp, and then do an ADB shell TWRP install of those files. TWRP, kernel, then magisk, in that order. I always reinstall all three, just to be on the safe side, and have never had any issues. Takes a little while, but not as long as redoing the whole freaking thing:silly:
Looks like you figured it out, before I finished my reply
