[Guide] Re-lock and Un-root **3G & 4G** Xoom

##PLEASE NOTE##
These files are from Motorola's Development site and I take no liability with anything that happens with your device if something goes wrong.
DO NOT ATTEMPT TO FLASH THIS FILE ON ANYTHING BUT THE VERIZON WIRELESS MOTOROLA XOOM Z600 (3G MODEL) OR YOU WILL HAVE A SHINEY PAPER WEIGHT!!!!

You're going to need to have the Android SDK installed. You can download it here:
ANDROID SDK - DOWNLOAD
XOOM Firmware Downloads:
[3G|MZ600-HRI66]
[4G|MZ602-HLK75D]
Unzip the files in MZ600_HRI66.zip and move or copy them to the /platform-tools folder in your SDK folder.
Connect your Xoom to your computer. Type:
Code:
adb reboot bootloader
Wait for it to reboot into the bootloader.
Type the following commands, waiting for each to finish before continuing:
Code:
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash recovery recovery.img
fastboot flash userdata userdata.img
fastboot erase cache
You've now successfully flashed your Xoom back to stock. Now it's time to relock the device. Type
Code:
fastboot oem lock
wait for the menu
then press the volume-down button.
Then press the volume up button.
It'll take a minute or so, then reboot. You're now completely back to stock and ready for the update.

So if you are on Three . One you can use this to revert back to out of the box freshness?

Yes. That is correct. This will return your XOOM to 100% stock.

word!
I have already been thru the LNX 0x0004 debacle and it was absolutely no fun whatsoever.

well I got a stuck at moto logo for 10 minutes
I am going to try to fastboot oem unlock, reflash images again and fastboot lock to see if I get out of moto logo

second install fix it

So the HRI66 is the latest version on the Motorola site? I really need to get a grasp of their version numbers.
EDIT:
Never mind looks like HRI66 is the latest version Thanks anyway.

i was thinking that with the change to the bootloader in the 3.1 update we couldn't use previous versions img's. But I am glad we can return to stock and get this 4G update!

I'm following all those steps directly. Once I type in adb reboot bootloader, it says starting Fastboot protocol support. Once I try to type any other command it says not recognized in adb. Any ideas?

Dead link...

Did you extract all of the files in the ZIP into the 'tools' folder? The same one that adb is in.

Could someone help me,
After the rebooting device I got this massage :
Failed to boot LNX 0x0004
Starting RSD mode 2
Then stuck on Motorola logo. I can't enter the recovery mode.
What should I do ?
My Xoom is H.6.1-38-9 International version

This is what I was afraid of..... try searching the error you are getting. Not many options on how to fix.

i am curious about the LNX 0x0004 error. I know it comes from trying to relock with non-factory img's but what exactly does that mean? I am curious what actually causes the device to soft brick.

Finally I made it, .
I can enter to bootloader by fastboot method, flash the stock image, then relock my device.

Kinda having the same issue as dchurch... "adb reboot bootloader" reboots Xoom to the "M" logo with "Starting Fastboot protocol support," but I can't continue with nay further commands. My computer no longer recognizes the presence of my Xoom and my Xoom doesn't progress past this screen. I can boot it normally with no problem. I've extracted all of the necessary files into my platform tools folder with adb.. any input?

You can try manually going into fastboot as well... there are two ways to do this:
No matter what, power off the Xoom. Then, 1) Power on the Xoom and as soon as you see it turn on (within a second or two of the power on), press the Volume Down button, which kicks it into Fastboot. 2) If you miss the 1st couple of seconds and press Volume Down after 3-5 seconds, it will say "Android Recovery." You can then press Volume Down until you get to Fastboot, then press Volume Up.
My guess is that you have a different issue, something to do with your Fastboot image. Not sure if booting the Xoom into the OS and connecting with USB Debugging on will work or not to flash the files, perhaps maybe just the boot.img?

I also believe that when the Xoom says "Starting Fastboot protocol support", it is in fastboot mode and you can send the fastboot commands to the Xoom. If your PC does not show the Xoom as a device in your PC's Device manager, then you will probably need to load new/correct drivers onto your PC.

Did you make sure that adb recognized your device? Adb devices in the camaned prompt

D855 Stuck at Boot Screen

So I think I've gone and bricked my LG G3.
After the ROM I was using, cm-13.0-20160322-NIGHTLY-d855 (CM13 March 22nd) from here, kept freezing 20 seconds after startup, I went to update to cm-13.0-20160325-NIGHTLY-d855 (CM13 March 25th). I booted into recovery (TWRP 2.8.7.0) as usual and went to flash both the ROM's .zip file and an Opengapps .zip file using TWRP's queue feature. However, it appeared to get stuck at a line (unfortunately I don't remember what it said exactly. Something involving patching system, I think), so I pulled the battery. I get the feeling this was a super not good thing to do, as my G3 now sits at the "LG - Life's Good" screen indefinitely. Holding Power+Vol.Down does not boot into Recovery, and neither does holding Vol.Up and plugging into my computer activate Download mode.
I tried to be as thorough as I could with exactly the steps I took, so I'm just hoping someone can give me a few pointers on what I can do.
As I type this I had the phone connected to my computer next to me, and I've suddenly heard the Windows "Device connected" sound and the phone is now showing this in the top right corner, in tiny font:
Code:
[784670] Fastboot mode started
[784820] -- reset --
[784820] -- portchange --
Edit: When this occurred, a device named "Android" appeared under the "Other devices" tab in Windows Device Manager. It's got a yellow warning sign next to the icon, and Properties says that the drivers for the device aren't installed.
Perhaps this is relevant to getting it working again.

First you need the adb drivers for lg g3
Then you need proper partitions, depends what your starting system was, before cm..
then simply reflash them
fastboot flash aboot aboot.img
fastboot flash recovery twrp.img (because you don´t have one)
fastboot flash laf laf.img (this should fix the download mode)
Depending on what the system in original was and what the cm package installed...

Many thanks for the reply.
By ADB drivers for the LG G3, do you mean the Lg United Mobile Driver? I have version 3.13.2 of them, if that's what they are.
When I input the commands
Code:
adb devices
or
Code:
fastboot devices
nothing appears, so are there different drivers I should look for?
I'm not too sure how to "fix" partitions, either, but I'm guessing it requires ADB/fastboot.
The file aboot.img and laf.img, will I need to find somewhere to download them from?
Again, I appreciate the response.

In case you have the drivers not installed (the "android" device without drivers in device manager), try with "google adb driver" ->
or pdanet
however the lg one should be fine (if not -> try one of the ones I mentioned)

I used PdaNet to install the LG drivers, and inputting the command "fastboot devices" now shows
Code:
? fastboot
Inputting "adb devices" does not show anything, however.
I then attempted to flash a recovery, TWRP version 2.8.7.0 with the command "fastboot flash recovery "recovery.img"". However, the phone's screen showed the following:
Code:
[998960] Error: Command never completed
[998960] Error: Auto CMD12 Error
[998960] Error: Command never completed with errors
[998960] Failed Writing block @ 1
How do I fix the partitions and find the files "aboot.img" and "laf.img"?
Thanks for your help so far, I'm glad that there is progress now.

it has to be fastboot flash recovery recovery.img (where recovery.img is twrp.img, twrp.bin, recovery.img or similiar, without any quotations)
What happens when you try to enter TWRP? Are you doing it right? Hold volume down and power ---- wait for lg logo an release for less than a second and keep holding again.
aboot and laf are downloadable or extractable (from KDZ/TOT) -> use bullghosts kdz/tot extractor

I retried the command fastboot flash recovery recovery.img but it resulted in the same output as before.
I followed the exact instructions to enter TWRP but it just stays at the LG logo screen. I've held Power+Vol.Down for about a minute after quickly releasing it+pressing it again at the LG logo, but it just doesn't do anything.
I've found myself a Lollipop KDZ file. The CyanogenMod I was running, however, ran on Android 6.0 Marshmallow. Will I need a Marshmallow KDZ file instead?

I appreciate the offer to use Teamviewer to help me, but I think it would be best if you typed out some instructions in a reply to this thread so that others with the same issue can refer to here.

Solution
I've found a solution to my issue, at least.
Downloading "recovery.img" from here, putting it in the same folder as fastboot, and then using the command
Code:
fastboot boot recovery.img
booted my phone properly, into cm-13.0-20160322-NIGHTLY-d855 (CM13 March 22nd).
However this resulted in all data being erased, including internal storage.
After using Flashify to re-flash TWRP (just in case), everything works as it should.

Glad you got it working
Regarding teamviewer - it was an exploration mission so I would see how your device behaves, maybe wrong drivers, maybe..100reasons (I certainly would write it in here if there was a better idea on my side)

No problem, sometimes you have to trust people
There were people who asked for help, installed teamviewer and didn´t gave any control permissions (which is fine). But they were expecting someone is having soo much free time to explain things (which I would if I had time)
cheers, flad you fixed it

Fixed my G3 I was about to send to trash!

Thanks a million for pointing to this recovery file!
I was also in a situation where all my attempts to flash a recovery were failing due to:
Failed Writing block @ 1

The rest of my phone was unusable (no working recovery, no download mode, just the LG logo or this fastboot mode)
I tried several TWRP recovery versions & flavors, but so far, I only successfully reboot in recovery using CyanogenMod recovery file (download.cyanogenmod.org/?device=d855). Though I was not able to do much afterwards apart some adb commands that were not working either.
Code:
dd if=/dev/zero of=/dev/block/mmcblk0p20
dd: /dev/block/mmcblk0p20: write error: I/O error
This recovery img did the trick and I'm now back with a CyanogenMod ROM and a wiped phone.

Stuck in Bootloader - adb no devices - can't boot into system or recovery

Hey guys I'm stuck in bootloader on my taimen and I hope someone can help me.
I tried to update my OS from latest Android 9 factory image to Android 10 via bootloader, as I always do.
After executing the command
Code:
./flash-all.sh
I got a message that said that I should download and install the latest platform-tools from googles dev site, what I did. And I think that was my mistake. I downloaded the updated tools and replaced the old ones, while beeing in bootloader on my phone and connected to my MacBook.
Now I have a problem that whenever I try to boot in recovery or system I get the dead android Icon with 'No commands'. That wouldnt be a problem for me, if I could install a new .img to boot into system and start again. But unfortunately I cant find my device via adb. The List of attached devices is always empty.
What I have tried so far to solve this issue:
- tried 2 different cables and all USB ports I have - no success
- restarted adb several times - no success
- added vendor Id to /adb_usb.ini file like described in this post https://stackoverflow.com/a/7136003 - no success
Does anyone have a suggestion what I could try next? Any help is appreciated

Download Homebrew. And install adb in terminal, and try if that works . https://brew.sh/index_sv .
https://stackoverflow.com/questions/31374085/installing-adb-on-macos/32314718#32314718

I'm no expert but I thought that you should use fastboot commands from your MacBook terminal if you are in the bootloader and not adb commands. But I guess the fastboot commands don't work either since you wouldn't have a problem then!
Tips on getting to recovery mode from 'no command' screen:
https://youtu.be/P1RGEle3qN0

Hey guys thanls for your suggestions.
Fortunately I was able to resolve my issue. The problem was that I was on the wrong partition.
After setting the partition back to a with
Code:
fastboot --set-active=a
my device id appeared in the list of attached devices
Code:
fastboot devices
So I was able to reflash the flash-all.sh and now I'm on Android 10.

FastbootD not loading

Hi everyone,
For some reason I cannot manage to get fastbootD to run. When I type 'fastboot reboot fastbootd' I get the message: 'fastboot: usage: unknown reboot target fastboot'.
In some cases it does not show a message at all and simply shows me which fastboot commands I can show. I tried with custom recovery and with TWRP recovery (even when running it's own fastboot mode) but it never works. This is most likely the reason I am unable to successfully flash a custom software to the phone.
If someone knows what is causing this that would help me a lot!
Fastboot version: 31.0.1-7187441
ADB version: 31.0.1-7187441

After trying the reboot bootloader option 3 times it was finally able to go into fastbootD. Honestly I have no clue what causes this but it seems to work now.

1st of all, what is fastbootD?
I never heard about that, is it something other than fastboot?

Question What to do?

Hey guys,
I have Lineage OS installed on my Poco F3. I have (at least not really) never experienced any issues with Lineage so far. Everything has worked really smoothly up until I updated the latest version of Lineage OS. The update took ages for some reason and now my Lineage is incredibly unstable.
It doesn't show any of my contacts anymore, play services and the app store crash all the time, giving me notifications non stop.
I tried manually updating the firmware as I figured something went wrong (obviously) but my device does not talk to my computer over a usb. I went to the settings and those showed me that the file transfer option is unclicked, I can't seem to change it either.. Really annoying.
Does anyone know what to do? I don't want to factory reset because of my authenticator. Shall I just wait for the next update and hope it's fixed?
Kind regards, pls halp!!

You could try going into Fastboot mode (https://www.hardreset.info/devices/xiaomi/xiaomi-poco-f3/fastboot-mode/), boot TWRP (fastboot boot TWRP.img) and then change boot partition (e.g. from a to b).

Make sure you don't accidentally flash the twrp.img but use the "fastboot boot twrp.img" command!
Edit: just realized you can change active boot slot with just fastboot, i.e. no need to flash twrp):
Just boot into Fastboot, find out active boot partition:
fastboot getvar current-slot
And then change accordingly, i.e. if above command returns "a" choose "b" and vice versa wit this command: fastboot set_active b
