[Guide] Re-lock and Un-root WI-FI Xoom Build HWI69

This is for Re-locking and Un-Rooting the US WIFI Xoom BUILD HWI69 ONLY
This is for use only on the Wifi-Only Xoom HWI69 build. Check your build number before you install!!!
Please note the following information does contain official Motorola images from a non Motorola source. The information in this thread has been tested, however I can not confirm that it will work for every situation. In no way will I or xda-developers.com be held accountable for any damage resulting from using this information. Use the following with extreme caution.
1. Download the necessary files from here:
http://www.android.net/forum/downloads.php?do=file&id=39
2. Unzip the files to the directory you will be running ADB from.
3. Enter the following commands into the command prompt
adb reboot bootloader
Xoom will then reboot into bootloader screen
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 lock
After the final reboot you should be back to stock, Locked and Un-Rooted.
note: If you are using Terminal on a mac your commands should include a ./ before every command like this:
./adb reboot bootloader
Xoom will then reboot into bootloader screen
./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 lock

fixed build number, thanks for that! ya i just did it yesterday and worked no problem.
everytime i run commands in terminal on my mac i have to put the ./ or else it wont work, never worked for me just typing it in normally

I just tried this and it works great! Excellent work OP!
After unrooting and unlocking and My 3.1 updates kicked in right away..... I think I will be running stock for a while

I flashed 3.1 from clockwork. Will this still work? Does the Xoom check for version before booting? like some HTC and Motorola phones?

check your build number in settings>about phone, it has to be HWI69 in order for this to work

I have that model. I was just making sure it wouldn't be a problem that I hate flashed the 3.1 update

what format are these imgs in?
I am trying to unyaffs them but it is not the right format

Your trying to what?

The build number does not matter. All that matters is you flash official images for YOUR device. For example the US wifi images on a us wifi device. The same goes for the 3g. Just do not relock the bootloader with out those images flash onto the device.
In a year from now your device could be running ice cream sandwich with who knows what build number. Unlocked bootloader = flash back official images when ever you want.

I am trying to get the data out (on my pc)
I lost all the default stuff that come with the xoom.

Does doing the ota to android 3.1 change build number from HWI69 to HMJ37?

worked nice thanks man... sad to say im taking this thing back today to get the less cool looking transformer for 200 dollars less... same thing just looks not as cool... supposedly screen display is better too... thanks again..

yes it does... ur wifi onnly us xoom should have been that to begin with before the ota...

Gave all credit to those it belongs to.

Tried this last night but used HMJ37 instead of HWI69 and got myself into a weird situation where it wouldn't boot (stuck on Dual Core screen). Had to power off and use vol+ to get to fast boot and unlock again.
Is HWI69 the only build that can be oem locked ?

Thanks!
Worked perfectly, thank you for taking the time to post this useful thread.

need help flash stock image

I am new to android and this is my new first android.
I saw postings yesterday says OTA 4.0.2 rolled out, and people got it already and there are manual way to get it, so I decided try to work on it. I followed the guide how to unlock bootloader and how to root, the first steps went through, but I can get through the last steps because it isays 'waiting for device', i tried everything. somehow I see the bootloader is unlocked.
I installed the stripped 4.0.2 update from here . I used odin mode. now my battery is dropping 1% every few minutes.
I want to flash restore stock image see if I can fix the problem. I trie flash it with odin, but oding crashed.
can anybody help?

Are you running Linux??
Edit:
From Windows or Linux (only tested by myself of Debian Linux) with fastboot in your PATH:
Reboot into bootloader (adb reboot bootloader)
fastboot flash bootloader bootloader-toro-primekk15.img
fastboot reboot-bootloader
fastboot flash radio radio-toro-i515.ek02.img
fastboot reboot-bootloader
fastboot flash radio-cdma radio-cdma-toro-i515.ek05.img
fastboot reboot-bootloader
fastboot -w update image-mysid-icl53f.zip

windows.
USB driver is installed when phone is normal mode. but in orin the usb driver does not show.

Moved. Please don't post in the wrong forums.

this is GSM version.
where do you get the image files? also why I can't do in orin?
is there a simple way to flash the factory image directory or any gui tool to do it?

Files are here: http://code.google.com/android/nexus/images.html
Make sure to pick the right one: yakju is GSM and mysid is CDMA
Download the tgz file and extract it (might need winrar on windows IDK)
All the Radio,Bootloader,Recovery and system files are included. The only way I know how to flash these files is fastboot, which imo is a safer way than odin - though I have not really used odin before.

can you explain how to use fastboot. I tried vol-up+down+power, it boot into fastboot, I supose it is, on bottom, it says 'unlocked'. what should I do next?
I am really new to this. I don't want to mess with me device like putting custom rom or stuff. I just want keep it original, it looks better that way. I do not want to add any fancy stuff to it unless they are really good. I used to do tweaks with windows mobile, they had better gui tools to work around make things easier.

You need the android sdk installed on your computer. Read this guide:
http://www.xda-developers.com/android/adb-easy-tutorial/
There are also a handful of threads in this very forum answering your same question. A few of which I have given step by step guides myself. Do a quick search.

I downloaded file from
http://groups.google.com/group/android-building/msg/2cd2b16ed56a7e84

the battery is still dropping.
is there a way to reset to 4.0.1? I am not sure what is causing the problem.

I really need someone to help me...Please...im on the verge of suicide here
i unlocked and rooted, dl'd cwm.
i dl'd the SDK package (i dont have platform-tools, i have tools)
i put the cwm image, and the tgz files on the root directory (there no /sdcard)
i turn on usb debugging
i load bootloader
i launch cwm recovery
i navigate to the sdk folder (cd c:/ > cd sdk > cd tools) then type fastboot -w update image-yakju-itl41f.zip and get an invalid command error ..that didnt work so i copied the tgz and cwm file to the folder which contains the adb stuff and try again..same result
PLEASE HELP...i know im an annoying **** n00b thats wasting youre time but ive been at this since 9am PLEASE

You dont put the files on your phone. They go in the same folder on your computer as fastboot.exe

put files in ur tools folder inside sdk and you fastboot -w update image-yakju-itl41f.zip and get an invalid command error ,,,should of been ,,, fastboot flash -w

oh god didnt realize i got any replies.
so ive gotten past that part now i have a more frustrating problem...installed platforms-tools from the sdk manager, that enable me to get this:
c:\sdk\platform-tools>fastboot -w update image-yakju-icl53f.zip
archive does not contain 'boot.sig'
archive does not contain 'recovery.sig'
archive does not contain 'system.sig'
< waiting for device >
but when i open the image zip the boot recover and system are there.
the waiting for devices deal, in device manager Android Phone is listed with sub Android ADB interface...driver is installed and device is recognized...why does it still say waiting for device...thank you guys so much.
If I get this working today I promise I will make a small donation to both xda and those that help me.

you need open the zip then extra the tar inside it with 7 zip, then copy all 4 extracted file into sdk folder, or same folder with fastboot. then run fastboot. you can use my output in page 1. type exact same thing.

How sure are you that the phone is in bootloader mode at the time of flashing? Try executing fastboot devices first to confirm that fastboot can see the phone...Then what the OP has suggested above or do what you were doing.

Hey I think I explained this in another post, not sure where, but fastboot devices initiates a blank command line. Doesn't show anything...which is odd though because I downloaded the right drivers from Samsung, it's recognized on my computer and it worked with ODIN (although updating through odin actually bricked me and forced me to restore)

If fastboot is showing a blank command line, then it means that it can't see your phone. Anything done after that is not going to work. It could then be one of two things, i.e. either your setup is not correct or your phone is not in bootloader mode. Can adb see the phone normally from your PC, i.e. can it see it when you call 'adb devices' or can you see the logcat output?
With the former, I can suggest that you check if the installation is correctly done? As with the latter, I tend to get adb to reboot the phone in bootloader by issuing a 'adb reboot bootloader' and is far quicker than the button-press option.

did you install sdk and driver? when your phone in normal mode, plug in usb to pc, in device manager, you see android driver?

I tried again. whe I get here
C:\android-sdk\platform-tools>fastboot -w update image-yakju-icl53f.zip
archive does not contain 'boot.sig'
archive does not contain 'recovery.sig'
archive does not contain 'system.sig'
but the files are actually in the zip file.
the process still finished.
did it skip those files?

I think that has something to do with the .sig verification settings
..same thing happened to me but image flashed fine and everything seems to be running smoothly. Crazy how I struggled with this so much at first its actually an extremely simple process.

Try pressing power, volumeup, and volumedown, all together until you see the blue menus, once you see that, do a factory reset and reboot.

doesnt that bring me to the bootloader?
edit: now i cant mount sd card in recovery after doing this....i think this is why its not booting....any help?

Don't we need do the following code before unroot?
Code:
fastboot erase boot
fastboot erase cache
fastboot erase recovery
fastboot erase system
fastboot erase userdata

if you really bricked yours as badly as I did, you might have to re format one or more partitions.
Fastboot format partitionname
Then fastboot flash partitionname imagefilename.

Don't think so, it overwrites everything so i don't think it matters.

I've fully flashed the factory image and it just sits there seemingly looping.
I've flashed the stock recovery, from Stockroms . net, the bootloader and image from the Google Developers page and it still just sits there.
Anyone have any ideas?
I've also tried erasing all partitions and then flashing again. Right now i`m willing to try anything

Why not link to the official source?

The batch file I mentioned above for the N7 did this, and a guide somewhere else written before said that this was necessary due to some bug in the past (I guess something wasn't being overwritten properly).

Hmm, I did just the 'fastboot -w update image-mantaray-jop40c.zip' since I didn't want to mess with the bootloader, just reflash the stock rom.
Got the red triangle with !, rebooted and still got it, but after a few minutes it rebooted by itself and worked. Hopefully it was just doing some kind of first boot thing or wiping stuff.
EDIT: Also seems to have flashed over my recovery, but no biggie.

Where did I go wrong?

So I somehow bricked my N10 (all I did was flash CWM recovery, and then I couldn't mount /sdcard and it bootloops) so I tried this.

So I was kind of stuck at same spot you were I believe, where after the cache the device autorebooted and then hung on the splash screen.
I booted into the (now) stock recovery and formatted and wiped cache and it booted up fine. Hope you have the same luck.

I did exaclty what the OP said and I am at the boot up boot image of the X that is multi color and it just loops there.

I'm still stuck in bootloop. Entering recovery from fastboot brings up the laying android icon with the red triangle/exclamation mark.
What steps do I take next?

Press power and volume up and let go, you'll get various recovery options. Select wipe data and confirm. It'll wipe, then reboot.

Looks like today I'm more stupid than usually. I tried pressing power and volume up both in fastboot and in recovery mode, neither gave me recovery options. I know I am close but I can't nail it...

Return LG Nexus 5X to original Google ROM

Hello,
I have an LG Nexus 5X (Bullhead?) running PA 7.3.1-RELEASE (Android 7.1.2). It had PA installed on it when I purchased it from ebay some six months ago.
I really would like to go back to the original Google ROM but am struggling to do this.
I've downloaded SuperSU but when I run it I get "SuperSU SU Binary is occupied" and a "HOW TO SOLVE" button.
Clicking "HOW TO SOLVE" takes me to www supersu dot com faq subinaryoccupied which reassures me that: "Only needs a coffee's time to make it happen" and a Community link and Message Us link. Community Link returns a 502 Bad Gateway response (not very reassuring!), the Message Us link goes to a facebook group (SuperSUofficial). Is this route even worth entertaining? I feel I'm only at the tip of the iceberg in getting my phone returned to factory/OEM status.
Any advise would be most appreciated. (Sorry ,not allowed to post links as I'm under the 10 posts requirement)
Thanks, BloodBaz

Follow #10 in this guide, or #11 if you want to retain the contents of the phone's internal storage. You don't need SuperSU for anything.

Thanks Jacquestrapp. I'm struggling at the very first step.
Here's where I'm at:
Step 10 (How To Flash The Factory Images (And Return To Stock)) has the prerequsite that I have to unlock bootloader (section 1).
Gone to section 1
Enabled Developer mode (was already enabled)
Enabled OEM unlocking
Enabled USB debugging
Powered off phone
Booted into Bootloader (Power+Volume Down)
Connected phone to PC via USB cable
Opened command prompt, gone to platform tools but as you can see, I'm not connecting here:
Code:
C:\android\platform-tools>fastboot devices
C:\android\platform-tools>fastboot devices
C:\android\platform-tools>adb devices
List of devices attached
00cad250a0599972 device
C:\android\platform-tools>fastboot reboot
< waiting for any device >
My PC is the latest Windows 10 Pro (64-bit).
I have an LG Nexus 5X (Model LGH791).
And I'm guessing I've not got the right drivers installed but I'm struggling to find where to get them (I'm in the UK)
Here's where I've tried:
Attempt 1:
Followed the same guide to "Google USB Driver Install": https://developer.android.com/studio/run/win-usb.html
which takes me to: "Click here to download the Google USB Driver ZIP file (ZIP)" (latest_usb_driver_winodws.zip 8.3MB).
Downloaded, unzipped.
Gone to Device Manager but my phone doesn't appear under "Portable Devices" or anywhere else in device manager.
Attempt 2:
Gone to LG's website, entered model which lead to this page:
https://www.lg.com/uk/support/softw...00008356&subCateId=CT00008358&modelNum=LGH791
(but alas, no software!)
Can anyone advise on how to get the phone and PC to communicate?
Thanks
Chris

You mentioned that your phone has a custom ROM on it (Paranoid Android), which means it almost certainly has an unlocked bootloader. If you reboot the phone, the first thing you see when it reboots should be a message to this effect, advising you to lock the bootloader.

Thanks, yes it does! Sorry, I not good at this. So the pre-req for section 10 is already done.
(I'm assuming I will still need to get adb / fastboot working at some point though).
I'll start looking into section 10 now. Thanks.

Are you connecting the phone to the PC through a USB hub? If so, try connecting directly to one of the PC's built-in USB ports. It's been a while since I first set up my PC for adb/fastboot so I'm not sure what to do about the fact that fastboot doesn't show the phone. I think I used the Android SDK manager, and not the ZIP file, to install the USB drivers.

No, directly onto USB port on top of PC. Tried both ports on top and a USB 3 port in the back. Still no sign of the phone in Device Manager.
I've got a laptop - I will try that next.
After that I will install the Android SDK manager (although I was hoping to avoid this for a one off job).
Thanks.

Okay, so I *think* my laptop is recognising the phone, however I still don't see the phone under Device Manager > Portable Devices or Device Manager > Other Devices (in fact, neither folder exists on my Laptop in Device Manager). However I have got "Nexus 5X" listed under Device Manager > USB Devices.
I'm now following instructions in section 10 of the guide you have given me:
"Download the latest build via the appropriate factory images for your model (Nexus 5X/Bullhead) here (https://developers.google.com/android/nexus/images?hl=en)".
For me this is 8.1.0 (OPM7.181005.003, Oct 2018) under "bullhead" (https://dl.google.com/dl/android/aosp/bullhead-opm7.181005.003-factory-e23fac1c.zip)
I've done the appropriate unzips and copies and I have the following folder set up:

The next instruction is to "Boot into the bootloader and connect your phone to your PC via usb cable."
So I shut down my phone then booted it back up again using POWER +VOLUME DOWN buttons to get the screen with the big fat green START option and FASTBOOT mode showing
Connect USB cable to laptop and phone
BUT... now the device isn't showing anymore in Device Manager and running adb devices -l just says "List of devices attached" and nothing underneath!! Grrrrr!
Q1) Should the laptop still be able to communicate with the phone when the phone is booted into the bootloader?
Q2) Could there be something fundamentally wrong with the phone that is causing it not to be recognised?
Booting up the phone and disconnecting and connecting the phone a couple of times re-established the device. This time I was able to run adb reboot bootloader but as soon as the phone starts to shut down for the reboot, the connection to the laptop is lost and the laptop shows an error popup (temporarily) (wish I knew how to keep the popup visible but it was something about an error with the USB device).
Q3) Should I select RECOVERY MODE before I can expect the USB connection to reconnect? Documentation just says to go into bootloader (with the menu)
Any more advice is appreciated. Thanks, Chris

That last command should be fastboot devices, not adb devices.

Yes, but using fastboot commands, not adb commands. With the phone in bootloader mode (the green screen with the big Start sign), you should see it listed after the fastboot devices command. Here's what I see:
Code:
C:\adb>fastboot devices

The phone's type-C port can collect lint, and plugging the connector into the phone compacts the lint. Over time, the lint layer can build up to the point where the connector no longer makes full contact with the port. I don't think that's your problem though.

@Jacquestrapp, thank you for your replies. You've been a life line.
After a couple of hours I think I've now managed to do it. I've tried two laptops, multiple USB ports and two USB cables. Whatever is happening, the PC/Phone connection seems very tempremental and I have to unplug and replug in the USB cable after each reboot. However, as you say, the fastboot commands did work after I figured this out, and from the fastboot screen. Also, whenever the phone rebooted or I disconnected the USB cable, the error message was as per attached screenshot.
So, I ran the following commands:
Code:

The pre-google animation too ages and eventually talked about corruption on the filesystem. This is presumably because it had Paranoid Android installed on it previously. So I took the option to wipe everything (I don't have anything precious on the phone that isn't already backed up) and I've got myself back to stock Google and I'm very happy!
Thanks again for your support @Jacquestrapp.
The only thing I haven't done yet is relock the bootloader.
The guide states this warning:
"Important: do not relock your bootloader unless your phone is fully stock. You must flash the factory images first in order to remove root and custom recovery (if you have them), if this precaution isn't taken you may end up with a brick. Please see section 10 of this guide for full instructions on how to return to stock"
Now that I am booting up fine in standard Google Android 8.1, is it okay for me to issue the fastboot oem lock command? I'm not going to kill my phone am I? If it's a "yes", then I'll probably leave it a few days before I actually do it.
Thanks

You're welcome. I *think* you are OK to re-lock the bootloader, but I've never done it, so I can't say with 100% certainty. Both of the 5Xs in my house have been running custom ROMs since I bought them. Also, if the USB connection is as temperamental as you say, take a toothpick (or something else thin and non-conductive) and poke around gently in the USB port to see if lint is the problem. It probably isn't, but it's easy enough to fix if it is: just dig all the lint out.

Bricked even though I can fastboot?

So while flashing an update, my Pixel 3XL turned off and now it only loads in fastboot (every other options goes to black screen). On the fastboot screen I get "Device state: error!" not locked or unlocked. When trying flash-all.bat, here's the read out. When I exit, nothing has changed. I can still only turn on the phone in fastboot and no other options. If anyone has any ideas, I would greatly appreciate it!

Do you have the current platform tools? Also, use a C>A USB cable and not a C>C.

Yup, using a C to A cable. Downloaded the tools today so I'm pretty sure it's more of the device state error! problem and the error of no response error during flash.

No answer about the platform tools, but had you updated the phone before this way? If not, different computer, cable, port, etc. The platform tools haven't changed since a few months before nd of last year, so if you had done this before that part should be safe...
Did you confirm the file download and make sure that it was not corrupted when you unzipped the D/L? Otherwise, the above post about using the OTA through recovery is a good option.
P.S. It helps if you quote the person trying to help so that they know there is an answer.

How do I sideload the ota if I can't get into recovery? All the menu option through the volume rocker in fastboot leads to the device turning off.

Every now and then I have to swap ports on my computer because I'll get weird errors, not sure if I've seen this one specifically though. Swap ports, swap cables, mix and match until it works or you go through every option you've got.
Speak gentle words of encouragement too.

Have you tried the flash-all besides since the initial try? If not, I would definitely retry. Perhaps try changing slots from fastboot and see if you can boot to system or recovery (for OTA or factory reset) or run the flash-all from the other slot.

Sorry, but I just got back online (been one of those nights). Looking at all the back and forth, I feel like there is a communication gap between you and those of us helping. There are questions and suggestions unanswered. For one, I never saw a reply to if this is the first time you are attempting to update via a flash-all on the same computer/port/cable/etc. That will answer a bit about your knowledge and the hardware functionality. If all that is a go, the only thing that jumps out at me is the possibility of a bad download or something easy to remedy like a command problem or file location/path issue. Have you checked with Google? I know that getting a replacement sucks, but you may need to start over. The folks here have done this tons of times and got back from bricks probably more severe than yours. I have never seen a device that could get to fastboot not be recoverable if all of the things we are talking about are being executed properly, but there is always a first like a serious phone hardware failure that nothing is going to solve except for a replacement.
One thing I see is the PS location. I know there are some commands that don't play nice in PowerShell, so type 'cmd' from PS and get to a standard command prompt.

I had the exact thing happened to me on my Pixel 2 XL but nothing worked,
not even the "Duce Script". I decided to use the "Skip Soft" tool as my last resort
and to my surprise it worked and fixed it in less than 10 minutes!
Unfortunately the Dev hasn't added the Crosshatch yet. I suggest you download it
and ask him to add it in the "Device Support" section, he''ll add it once he sees more requests.
Good luck.

If all that is a go, the only thing that jumps out at me is the possibility of a bad download or something easy to remedy like a command problem or file location/path issue. Have you checked with Google? I know that getting a replacement sucks, but you may need to start over. The folks here have done this tons of times and got back from bricks probably more severe than yours. I have never seen a device that could get to fastboot not be recoverable if all of the things we are talking about are being executed properly, but there is always a first like a serious phone hardware failure that nothing is going to solve except for a replacement.
One thing I see is the PS location. I know there are some commands that don't play nice in PowerShell, so type 'cmd' from PS and get to a standard command prompt.

My apologies, I thought a previous comment mentioning computer/port/cables that I responded to clarified this. This is not the issue as I've done it with multiple desktops and multiple USB A to C cables. Even when attempting to change from slot B to A I get the device state error, which I've copied in another post on here. Isn't that the problem here? If I can't figure out a way to get around the fact that there's no response when trying to determine the lock state, I don't think we can fix the problem here. I don't see how this would have to do with being in powershell or not or being a bad download. Since most things fail in fastboot because of this error, this is what I was trying to get more info on to get corrected as it clearly seems to be the heart of the failure.
Unfortunately a lot of the back and forth is because of the repetition about cables and ports or asking me to recover which I appreciate, but I stated choosing recovery sends me to a black screen. When there's been actual commands to try in fastboot, I've posted the results they've given, but it still comes back to " FAILED (remote: 'error getting device locked state No Response') "

I appreciate the reply. Some of the things are just things that take no real effort (like downloading/extracting the factory image again to be safe), while the PS thing was just to make sure that if folks are sending commands to try that they are sending the right ones. The question about whether you were using a Mac or Linix (that I think has been deleted since I read it) got me thinking about that and not that running the flash-all batch would react differently.
Last thing, have you tried anything with the TWRP .img version like changing slots or even doing a factory reset?
