Don't work,
I give up
Thanks in advanced. All comments can help!

I have a tablet I can depure via USB and where I can root the tablet. But if I connect to the internet, the "registration and password" of university program enters and is saved (even after formatting it is stuck on this screen) blocking the tablet, I believe that after the internet loads, it installs this locking program ... What would be the name of this type of application? I'd like to know, how remove this app, to If connect in internet, we can block (and try install TWRP via internet with TWRP Management)...

Hello everyone !
I've been trying to resolve this issue for weeks. I have a tablet that I can't unlock (it's super hard, it's like Dark Souls of tablets). Well let's start.
He has a program that blocks asking for password and user (this a old from a university), where you request access via wireless or 2G/3G. without it you can't access it, so I believe I have to change his firmware instaled in, but I'm having a hard time to make it.
• Let's go to basic product information:
The chip is a RK3066 (same from TV BOX based on rockchip).
The model is YPY L1050 from POSITIVO (it's from Brazil).
- Software and Items
I have the drivers installed (correctly);
I have adb installed;
I have SD_Card;
I have acess from PC;
The tablet is unroot;
• Back to the items:
So, the good news is that I have the same tablet model, unlocked (with another type of ROM that I am unaware of). That works normally, without problems. Well, I saw a procedure that basically it is possible to extract this image from the good tablet, to the locked tablet. I did that, I ended up extracting a series of .img files from the unlocked tablet: boot, cache, kernel, system, etc... ok.
• Trying a extract from unlock same tablet:
I try transfer the copied files from "good unlock tablet" (extrated with AndroidTool), and put in (with the same tool) in the lock tablet... There is a problem, even before starting the operation, I have the error "Test Device Fail ", in the last is not possible to transfer files via USB (I can only do commands like" ResetDevice ", or export the images from the blocked tablet via AndroidTool... and yes I have the drivers instaled, commands like adb sideloader in the fastboot works).
• Trying a firmware found in internet:
Well, I tryed to download the firmware found on the internet corresponding to the device model, but unfortunately I have the same error as above. I download the .img firware original and using the RKBatchTool and have the same error (the operation don't start, give "Test Device Fail" in "Upgrade" and "Restore").
I believe that both operations do not accept transferring via USB.
PS: The tablet unlocked the command of "TestDevice" works fine.
• What I was thinking of doing:
1 - I think I need to take the all .img(s) files extracted from the unlocked device, put it in a single image (.img), put it in a SD_Card and in the "fastboot" take the option "update rkimage from external storage". But I don't know how to do this. (I try search for it);
2 - Somehow being able to do "apply update from external storage", maybe doing the same procedure above with an "update.img", but I also don't know how to do that (put all img. files together in the form of a one update.img).
3 - Have anothers options, like "apply update from ADB", the PC response this conection with tablet, (I can see the device with ''adb device'' cmds in sideload mode in PC). The problem is that I don't know how I'm going to send the .img file, if I send it inside a .zip (I even tried that, send all the .img files inside a .zip to see if it works. The tablet arrives to read the files but in the end the operation aborts). So my knowledge is lacking in this part.
4 - Another would be such a "ROM Dump." I'd like to do a "ROM dump" with an SD card, I even researched it on the internet but I didn't find this procedure to rockchip (only for Amlogic).
With SD Card:
There was a youtube that managed to unlock a tablet like that, but it was a previous model that I'd like to unlock (and different version of firmware, android etc). His method was to put a bootable sd_card, but he doesn't explain how he does it (he only gives the file done) and looking at the files internally, I just think they were converted to linux formats (system.tar.gz, userdata.tar.gz, some .sh .so files, and a bootenv.img, uImage etc) and with completely different names from .img... It is a pity that it is not for my Tablet model .
Well, that's it in the end, I need to change the firmware and I don't know how to do it.
PS: I tried other operations/methods as well, but I will not comment so that this post doesn't get big.
Thanks in advanced. All comments can help!

Instead of trying to package the .img files into one file, you should try flashing each .img individually via fastboot using commands with the following structure:
fastboot flash <name of partition> <name of partition.img>
The following commands are examples.
fastboot flash system system.img
fastboot flash boot boot.img
fastboot flash cache cache.img
fastboot flash kernel kernel.img
You will need to use a separate command for each individual .img.

Hi, thanks for the reply. Well I can make it via adb sideload? I can't use the command "adb reboot fastboot". Because this command "adb reboot fastboot" only turns off the tablet don't restarting into fastboot/download mode (just turns off). But If I manually enter on the bootloader, I can access the adb sideload option, where the adb install on computer can detects the device via the "adb devices command" with sideload.

It isn't going to work via adb unless the device is rooted and then it won't be via adb sideload, it would be done by using dd commands to dd the .img files directly to their partitions.

I just found a solution. It requires some tinkering, though.
I had to use a machine running windows 7, because that's the only OS that the drivers worked.
Download the firmware for the Ypy L1050F here: https://www.stockrom.net/2018/07/l1050.html
It comes with the drivers, the ROM, and a tool called RKBatchtool 1.8
You'll have to decompress everything, open RKBatchtool and choose the firmware that is in the ROM folder (Not the DEMO one).
Now comes the tricky part: You gotta undo the 3 screws aroud the tablet, then pry it open with your fingers(remember to remove microSD and SIM first, to avoid breaking stuff!). I recommend startind by the side with the usb, hdmi and power ports to get some leverage. The back cover should pop right off. Then you have to locate the NAND chip in it. Should be a Micron one with 48 pins. The small circle at one of the corners of the chip represents pin 1. Plug your usb cable to the tablet. With the tablet TURNED OFF, use a SIM removal tool or very fine tip metallic screwdriver to short pins 17 and 18 on the NAND chip and plug the power jack into the tablet. RKBatchtool should show that a device was connected. You can release the screwdriver now and just click the "Upgrade" button in RKBatchtool. Now this is very important: DO NOT UNPLUG your tablet until everything is done. It'll tell you when it's done uploading the firmware and checking it. Enjoy your new usable tablet!
I scoured the internet and found this procedure being used for TV Boxes with the same RK3066 SoC. AFAIK, nobody else managed to do it so far, so spread the word.

You are awesome. Broke the internet! I will follow your procedures to try to unlock it. Many thanks again xmas for you.

[TOOL] ADB Data Recovery (recover data from a phone with broken screen)

**UPDATE**
NEW VERSION
THIS RELIES ON ADB COMMANDS, SO IF YOU DO NOT HAVE USB DEBUGGING TURNED ON, OR A CUSTOM RECOVERY TO BOOT TO, THEN IT WILL NOT BE AS SIMPLE AS JUST RUNING THE PROGRAM.
Another user was having issues because he had an emulator installed, so I updated the file to give you the choice between an emulator, or device. I intend to update further to allow you to check for and select an individual device, that will come soon..
----------------------------------------------------------------------------------------------------------------
Recently my Galaxy s2's screen smashed, and, after replacing it with a GS4, i realized that many of my pictures were stuck on the internal sd card of the GS2. Being unable to turn on mass storage mode, I made a very simple tool that makes using adb pull a simple, painless process, even for the most computer illiterate of android users. Hope this helps if anyone needs it.
For anyone having issues...
If you had not previously activated USB Debugging, there are several steps you need to follow in order to enable ADB
SCREEN WORKING TOUCH BROKEN NO CUSTOM RECOVERY​first, if you can see your screen, and have access to an otg cable, plug a mouse in to the otg cable, and the otg cable into the phone. Use the mouse to enable USB debugging, or to transfer files.
HOW TO ENABLE USB DEBUGGING
SCREEN WORKING TOUCH BROKEN WITH CUSTOM RECOVERY​boot to your custom recovery ADB commands will work here. (usually hold vol- + pwr)
HOW TO BOOT TO RECOVERY
Once in custom recovery, connect the device to the PC.
open CMD and enter the following commands;
cd c:\android (this is your ADB path, c:\android is default)
adb devices
The result should be something like
List of devices attached
051a4dd5 recovery
^^this number will be different for you
if you get a result on ADB devices, then you can use the program

^^this number will be different for you
if you get a result on ADB devices, then you can use the program
SCREEN BROKEN TOUCH BROKEN NO CUSTOM RECOVERY​now things get complicated...
*The following is paraphrased from this site
1. download the custom recovery image for your device. Copy the recovery image to a convenient location on your computer, preferably with a short path. We will be placing it on the C Drive directly (not in any folder) and using that in the next steps.
Note: The recovery image should have .img extension. If it is in a zip file, extract the .img file from it.
I recommend clockwork mod non touch from this page
2. Power your device off and reboot your device to FASTBOOT or DOWNLOAD MODE depending on which type of device you have.
(most devices are fastboot, SAMSUNG typically uses DOWNLOAD MODE)
how to boot to fastboot or download mode
[FASTBOOT]​3. Connect your device to your computer via USB and wait till you see the PC recognize the device
to check if your device is in fastboot and connected use CMD and enter the following commands;
cd c:\android (this is your ADB path, c:\android is default)
fastboot devices
you will see a list of connected devices. if not, something went wrong.
4. Launch Command Prompt and type the following commands;
cd c:\android (this is your ADB path, c:\android is default)
fastboot flash recovery c:\recovery.img
5. Wait for the process to finish.
6. Turn device off then boot to your custom recovery ADB commands will work here. (usually hold vol- + pwr)
HOW TO BOOT TO RECOVERY
Once in custom recovery, connect the device to the PC.
open CMD and enter the following commands;
cd c:\android (this is your ADB path, c:\android is default)

Question
Hi! Can I use that to restore data not from sdcard but from internal memory of the device? I was storing photos on device memory on my Asus TF300T and now its bricked. I need to restore these photos, my girlfriend has something like 1000 of them from her trip to Caracas. Its very important for her. I already managed to connect the device through fastboot and I launched anb in cmd. What should I do next? Please help me guys

Yes, when it references SD Card it means the internal "SD" storage built in to the phone, not the removable one. It should work as long as ADB can connect.
Sorry for taking so long to reply, i really hope you got your pictures back.

Have you also installed ADB, as well as this software?
I'm also having an issue - I have installed java, java SDK and ADB, so I can now run the data recovery tool. But when I do I'm getting "error:device not found" - am I missing drivers or something? I couldn't get all the way on the ADB configuration, because part of it required me to do something on the device... anyway, looks like the computer isn't recognising the the phone at the moment.
Any help very gratefully received (phone is Samsung Galaxy S2).

I have the same situation right now. Managed to make your program work then I get the "error:device not found". My phone does show up in the computer folder(albeit not in mass storage mode), but isn't that what this program was made to work around?
My phone is a LG Optimus G with a smashed glass... The LCD still displays fine, but I'm stuck at my swipe lock because the digitizer is dead.
Thank you for your help and your wonderful program.
Thanks for this app. My girlfriend broke her screen and digitizer on her Galaxy S4. She never turned USB Debugging mode and has a lock on her screen. When using your app I get the same error when I use adb by itself which is "error: closed". ADB detects my phone but any command I use in ADB or with your app I get that same error.
Do you know how to fix this? Thanks in advance.
Thanks a lot man.
dude this tool is just amazing and does exactly what it promised. I was spending sleepless nights thinking about how to recover my data from my broken galaxy nexus and now that I have it I can rest easy. Seriously can't thank you enough for this. Just joined xda to thank you buddy.:laugh::fingers-crossed:
Getting an error "The system cannot find the path specified."
I start the recovery tool, set eh adb path successfully, and then I get this error. If I try running the recovery to pull the DCIM library I get this:
"error: device not found"
What can I do?
Thanks!
Either way this is an amazing tool, seeing how it helped some people already. :good:
Hi, Seem to have the same problem as many others, Device not found. I cant change to MTP mode on my LG G2.
I hope someone can find a solution to this problem.
Program seems amazing doh.
Hello,
This is really a great tool ! I was wondering if you could add the possibility to recover the external sd card aswell.
Device not found
Tried to recover a Samsung Galaxy S3 mini with a broken screen

Bricked Idol 3, need help recovering

I installed the OTA update last night and it's just looping through the "alcatel one touch" and "smart move" screens. It's been like that for hours.
I need assistance in getting into recovery mode, and hopefully getting my files off the device.
I have downloaded android-studio and am about to install it to get adb and fastboot, and have downloaded the drivers for the idol 3. At this point when it's plugged in, my computer doesn't recognize the device.
If you did not have usb debugging enabled BEFORE the boot loop installing adb and fastboot now won't do you any good. Are you still able to get into recovery and is it twrp or the factory recovery? Without a direct way to get the phone into bootloader regretfully the only solution is to send it in for warranty repair (or replacement via your credit card if you paid that way under purchase protection)
Are you trying to remove the data to prevent access by others or because you need the data? Did you make any backups to external sd or copied to the pc?
I as well am stuck in bootloop. Was able to get into factory recovery and reset phone several times. Still no luck. I have a TWRP backup, but how to I do a temporary boot into it? Only option available in factory recovery was to sideload via ADB, but no luck using fastboot commands there. Phoned Alcatel and they have referred me back to Amazon. Amazon only wants to refund me, won't exchange! Of course I bought at the pre-order price. Any help would be greatly appreciated.

The factory reset killed you....if you had usb debugging enabled prior and had not done a factory reset (which kills /data) you could have possibly gotten to an adb shell long enough to do an adb reboot bootloader. The problem is there's no way now to get you into bootloader....you can't get to it from recovery (factory).
If you purchased it by credit card you might see if their purchase protection (typically 60-90 days) allows a claim submission for a replacement....in this case they would cut you a check for the cost of a replacement after mailing in your old one. That's the only solution I see to remain at the $199 price.
You could also see if amazon will issue a $50 credit to your account in addition to return to allow for repurchase. Unlikely but possible.
Ok thanks for the input and advice. As a last ditch effort, is there a way to create or modify the twrp file as a "signed" zip file so that I could boot into it via stock recovery. This was how I rooted my old Galaxy S2, although it was a CWM recovery.

Nothing so far has worked in that regard...in fact I created a update.zip using "zipme" to replace the build.prop that another user says the factory recovery refused to process.
Without a full factory rom to pull needed info in or the source code to compile one we can't do some of the things which would "save" the device.

Can you post a screenshot where the option is? I'm not doubting your word but perhaps he's looking in the wrong place? I'm back on TWRP so can't look in the stock recovery myself.

There is no option for screenshot while the phone is in the stock recovery. I need a camera to take a picture of the menu. I can do this later. The menu however looks like this:
Code:
reboot system now
apply update from ADB
apply update from sdcard
apply update from phone storage
wipe data/factory reset
wipe cache partition
reboot to bootloader
power down
view recovery log

If it's right off the main page like that then I can confirm it's not on the 6045. It's been one of the main issues with folks bricking their devices...if their rom gets messed up and they have factory recovery they have no way to get into bootloader to do anything to repair the device. Seems alcatel needs to add the reboot to bootloader to our recovery. I wonder where we could report that.
Is there a way to "lock" recovery so the updates cannot replace twrp? TWRP allows adb access and reboot to bootloader.

This is a snapshot from the recovery menu of 6039y.
The short answer of your question regarding the "lock" is ... no. If a longer explanation is needed ... this is from the update file, a link to which was provided by you:
Code:
if ! applypatch -c EMMC:/dev/block/bootdevice/by-name/recovery:18393344:f9062580503eb61b315a5d12c5c6b3bb133aa4b2; then
....etc.
what it does is to check the sha1 sum of the recovery partition and if the sha1 sum doesn't match to f9062580503eb61b315a5d12c5c6b3bb133aa4b2 will continue with an overwriting of the recovery partition and then will apply a patch. It can't be changed because the whole update will fail.
yep no bootloader

Back to the "lock" question. Probably it is possible the OTA update to be slightly modified and then to be flashed through the TWRP recovery (there is an option in TWRP to skip the signature verification ... the verification will fail if the zip file is modified). But I prefer to wait for the OTA update of the 6039y, as I want to perform some tests with the upgrade.

I am in the same boat as OP re the state my Idol 3 (6045i) is currently in. I also unchecked superuser but did not unroot completely before installing the update. I have not yet done a data wipe through recovery though. Unfortunately, back when I rooted the phone I did NOT check the box telling the phone to remember the computer/RSA key for future use. As a result, now when the phone is stuck at the white/animated Alcatel boot logo I can see the phone under adb devices, but it shows as unauthorized.
One thing that did seem odd, was browsing through stock recovery when trying to browse to apply an update from either phone storage or the SD card, no files are showing up at all. All it is showing is the folder root ( /.. ) in both instances and nothing else. Even after I attempted loading several system update and twrp images (in .zip and .img formats) on the SD card from my computer, once loaded in the phone none of the files show up through stock recovery. Is this SD card not compatible/formatted wrong or is something else going on?
Is there any current method to gaining access to the phone via adb manupulating the adbkey files in the $User$/Home/.android folder? I do currently have the adbkey files on my Mac from connecting the phone previously. I'm assuming these files are uniquely generated hashes?
That is ridiculous if the 6045k has bootloader access from recovery and 6045i does not. What would be the reasoning for this?

Does the sha1 sum of your recovery happen to match f9062580503eb61b315a5d12c5c6b3bb133aa4b2 ? If so it could solve some issues but why do I suddenly think all 3 models have their own recovery?

Even after I attempted loading several system update and twrp images (in .zip and .img formats) on the SD card from my computer, once loaded in the phone none of the files show up through stock recovery. Is this SD card not compatible/formatted wrong or is something else going on?
Is there any current method to gaining access to the phone via adb manupulating the adbkey files in the $User$/Home/.android folder? I do currently have the adbkey files on my Mac from connecting the phone previously. I'm assuming these files are uniquely generated hashes?
That is ridiculous if the 6045k has bootloader access from recovery and 6045i does not. What would be the reasoning for this?

adb reboot bootloader won't work even with it showing unauthorized? If you can get into bootloader you can fix /system without messing up your /data (don't wipe data or you lose adb entirely...you may figure out how to add the correct hash if we can find how it's generated)
Here's some info on the hashes you might find useful taken from: http://nelenkov.blogspot.com/2013/02/secure-usb-debugging-in-android-422.html
Secure ADB implementation
The ADB host authentication functionality is enabled by default when the ro.adb.secure system property is set to 1, and there is no way to disable it via the system settings interface (which is a good thing). The device is initially in the OFFLINE state and only goes into the ONLINE state once the host has authenticated. As you may already know, hosts use RSA keys in order to authenticate to the ADB daemon on the device. Authentication is typically a three step process:
After a host tries to connect, the device sends and AUTH message of type TOKEN that includes a 20 byte random value (read from /dev/urandom).
The host responds with a SIGNATURE packet that includes a SHA1withRSA signature of the random token with one of its private keys.
The device tries to verify the received signature, and if signature verification succeeds, it responds with a CONNECT message and goes into the ONLINE state. If verification fails, either because the signature value doesn't match or because there is no corresponding public key to verify with, the device sends another AUTH TOKEN with a new random value, so that the host can try authenticating again (slowing down if the number of failures goes over a certain threshold).
Signature verification typically fails the first time you connect the device to a new host because it doesn't yet have the host key. In that case the host sends its public key in an AUTH RSAPUBLICKEY message. The device takes the MD5 hash of that key and displays it in the 'Allow USB debugging' confirmation dialog. Since adbd is a native daemon, the key needs to be passed to the main Android OS. This is accomplished by simply writing the key to a local socket (aptly named, 'adbd'). When you enable ADB debugging from the developer settings screen, a thread that listens to the 'adbd' socket is started. When it receives a message starting with "PK" it treats it as a public key, parses it, calculates the MD5 hash and displays the confirmation dialog (an activity actually, part of the SystemUI package). If you tap 'OK', it sends a simple simple "OK" response and adbd uses the key to verify the authentication message (otherwise it just stays offline). In case you check the 'Always allow from this computer' checkbox, the public key is written to disk and automatically used for signature verification the next time you connect to the same host. The allow/deny debugging functionality, along with starting/stopping the adbd daemon, is exposed as public methods of the UsbDeviceManager system service.
We've described the ADB authentication protocol in some detail, but haven't said much about the actual keys used in the process. Those are 2048-bit RSA keys and are generated by the local ADB server. They are typically stored in $HOME/.android as adbkey and adbkey.pub. On Windows that usually translates to %USERPOFILE%\.android, but keys might end up in C:\Windows\System32\config\systemprofile\.android in some cases (see issue 49465). The default key directory can be overridden by setting the ANDROID_SDK_HOME environment variable. If the ADB_VENDOR_KEYS environment variable is set, the directory it points to is also searched for keys. If no keys are found in any of the above locations, a new key pair is generated and saved. On the device, keys are stored in the /data/misc/adb/adb_keys file, and new authorized keys are appended to the same file as you accept them. Read-only 'vendor keys' are stored in the /adb_keys file, but it doesn't seem to exist on current Nexus devices. The private key is in standard OpenSSL PEM format, while the public one consists of the Base 64 encoded key followed by a `[email protected]` user identifier, separated by space. The user identifier doesn't seem to be used at the moment and is only meaningful on Unix-based OS'es, on Windows it is always '[email protected]'.
While the USB debugging confirmation dialog helpfully displays a key fingerprint to let you verify you are connected to the expected host, the adb client doesn't have a handy command to print the fingerprint of the host key. You might think that there is little room for confusion: after all there is only one cable plugged to a single machine, but if you are running a couple of VMs, thing can get a little fuzzy. Here's one of way of displaying the host key's fingerprint in the same format the confirmation dialog uses (run in $HOME/.android or specify the full path to the public key file):
awk '{print $1}' < adbkey.pub|openssl base64 -A -d -a \
|openssl md5 -c|awk '{print $2}'|tr '[:lower:]' '[:upper:]'
We've reviewed how secure ADB debugging is implemented and have shown why it is needed, but just to show that all of this solves a real problem, we'll finish off with a screenshot of what a failed ADB attack against an 4.2.2 device from another Android device looks like:

Just tested using adb reboot bootloader again and this is the result: error: device unauthorized. Please check the confirmation dialog on your device.
Something else I tried was running fastboot commands in the narrow window that the phone initially boots (black screen with Android logo) but that didn't seem to work either. I tried:
fastboot reboot-bootloader
fastboot -i 0x1bbb reboot-bootloader
fastboot -i 0x1bbb devices
I noticed if you plug the phone into the computer via USB while the phone is off, it will briefly power on to the Android logo/black screen before flashing the battery status once and turning off. Is this an opportunity to send fastboot or adb commands to the phone?
I'll try messing with the adbkey stuff later when I have time to dig into it.
There is a tool from Alcatel (TCL) which can perform upgrades of the device from a Windows PC. You can try it if nothing else helps. There are two COM ports available under Windows when the device is powered off and the USB cable is connected to the phone. This tool use them to perform some checks on the device and probably will continue with an upgrade (it says that all of your data will be wiped after the upgrade etc. so there is a possibility to overwrite everything with a stock image) ... there are instructions how to work with it. The link is from the French support section of Alcatel. Despite that the program has support for 6039 and 6045 is not clear for which of their versions.

The problem is we currently have no stock images in the format it requires to flash to restore the device. I would think those have to be available first?

You can't do fastboot commands until the phone is IN bootloader....so you'd have to do adb reboot bootloader
adb devices
etc....

It is possible the program to download these images from a server.
I found another interesting thing. The device has a download mode. It is activated when the phone is powered off and connected to a PC. You must wait the display to turn off after the charging battery symbol and then to press and hold both volume keys, after which to press and hold the power button (without releasing these for the volume). But still don't know what to do in this mode. No device is detected on my Linux box when the phone is in this state. Probably I should try in Windows.
Also when the Alcatel upgrade tool was trying to detect the phone I'm almost sure that one of the COM ports was
Qualcomm HS-USB Diagnostics 9006
there is a lot information for other devices how this can be used to unbrick your phone, so this is a some start. The images which the people flash through it are in raw format.

Shield Tablet not being recognized by .adb\devices command

Hello,
I am trying to flash an Nvidia Shield K1 tablet back to a factory image for the first time, and documentation from Nvidia is incredibly vague - and existing posts online just seem to say to refer to the Nvidia instructions.
I have enabled Developer Mode on my Shield. It is running Android 7.0, and when connected to my Windows 7 PC, I have made sure it is in "Transfer Files" mode, and not just "Charge USB" mode.
I have installed the current full Android Studio (the one with the UI, it's not some kind of "minimal install"), and according to the SDK Manager > SDK Tools window, I have Android SDK Build-Tools, Android SDK Platform-Tools, Android SDK Tools, and the Google USB Driver installed. I believe this gives me the "adb" functionality which seems to be a prerequisite for flashing a device.
When I open a standard windows command prompt, and navigate to the sdk\platform-tools directory, and run the ".\adb devices" command, it starts the daemon, but does not detect my Shield Tablet - it doesn't output anything after it says "* daemon started successfully *", just a blank carriage return, and then I'm back to the standard command prompt.
One possibility I had considered as to why the device may not be recognized is because there is a "SHIELD Family USB Windows driver" available online, which might be required for a Windows 7 machine to recognize. I can't link it because of absurd forum restrictions because I'm new. But the site is developer(dot)nvidia(dot)com(slash)shield-open-source. There, in the Shield Tablet K1 section, there 's a Windows USB Driver download link
But I downloaded that, and followed the instructions, and encountered an error
Basically, the driver download file for the official NVIDIA USB driver has a bit of a different folder structure than what the accompanying .txt instructions say, but I did find the android_winusb.inf file.
However, when I attempt to actually apply that android_winusb.inf according to the instructions, I get an error message, essentially saying the android_winusb.inf file is incompatible:
Basically, I get to the screen where there is the "Have Disk..." button, and my Shield appears in the "Model" section as a MTP USB device. When I try to apply the android_winusb.inf file, I get an error message saying "The folder you specified doesn't contain a compatible software driver for your device. If the folder contains a driver, make sure it is designed to work with Windows for x64-based systems." My Windows is 7 64-bit.
So, I can't even apply the official Nvidia USB drivers? Is this what's preventing adb from recognizing my devices? How do I apply the Nvidia USB drivers?
Note that I don't think I've ever put my tablet in Fastboot mode before, but I don't think that should be necessary for it to be recognized by the adb devices command, right? If my understanding is correct, adb is NEEDED to put the device in fastboot mode I think.
EDIT: I've also tried this on a Windows 8.1 machine - EXACT same problem.
fastest way to find the directory will be to search for fastboot.exe. For me, I'm running the "Minimal ADB and Fastboot" (I'm on version 1.31, that's probably not the latest, but it works) so I have a C:\Program Files (x86)\Minimal ADB and Fastboot\ directory.
Just search for fastboot and you'll find the directory. Or google the minimal adb and fastboot package and install it.

OK, I've downloaded the Minimal ADB and Fastboot v1.4 and installed it. I put my shield tablet into fastboot mode via the hardware volume and power button, and then I ran the fastboot oem unlock command via the Minimal ADB and Fastboot command window and it was successful.
I have gone to this webpage: developer(dot)nvidia(dot)com(slash)gameworksdownload, and searched for "NVIDIA SHIELD Tablet K1 Recovery OS Image"
I downloaded the 1.5.0 image, and extracted the contents.
Am I supposed to take those extracted contents, and paste them directly into the Program Files (x86)\Minimal ADB and Fastboot\ directory? And then I run these commands one at a time from the Minimal ADB and Fastboot command prompt (?):
fastboot flash recovery recovery.img
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash userdata userdata.img
fastboot flash staging blob
Yes, you can do exactly that!
However, I prefer to leave them on a different hard drive on my system. I keep them in a folder over on my e: drive, so for me the commands might be something like this:
fastboot flash recovery "e:\images\shield50\recovery.img"
and so on...
Before your first flash, make sure your model of shield matches the files!
I've got an original shield so I won't be using the K1 files, but I'm presuming you've got a K1 device so probably you are good to go. Happy flashing. Enjoy!

OK, on that developer(dot)nvidia(dot)com(slash)shield-open-source webpage, I downloaded the Recovery Images for v 1.3, v1.5, and 5.0. These are NOT the developer images - just the so-called "Factory Recovery" images.
My Device had done the 5.1 OTA update (which brought it from 1.3 to 5.1), and my whole point of trying to flash it was I wanted to revert back to 1.3. However, when I use the 1.3 and 1.5 images, when I use the "flash-all.bat" command using the Minimal ADB and Fastboot command line, the Tablet is put into an unusable state - the K1 tablet says "updating apps", and when it finishes, it just reboots to Nvidia logo, and goes to "updating apps", reboots, infinitely.
If I use the 5.0 image files, and use "flash-all.bat", the device is usable, and does boot into Android v7.0, but it doesn't prompt me about user settings and personalization like when I first got the device - it goes straight into the Android Nougat OS. Also, Bluetooth is completely hosed on it, which it wasn't when I fist got it. If I ever turn Bluetooth on a "Bluetooth Share keeps stopping. Close App" message keeps appearing and disappearing, and I can see that Bluetooth keeps turning off and on, for 5 to 10 minutes straight. It eventually stops if I poke around other system menus for some reason, even without changing any settings.
What is also very strange is even though this is supposed to be a "Factory Fresh" image (the 5.0 image I downloaded), my device still remembers my wi-fi network (connecting to it automatically), even though it was supposed to be wiped clean. Again, I used the "flash-all.bat" file that is included with all the image.
Any ideas why my device isn't truly resetting to the "Factory Image"? Possibly of note is that the official Nvidia instructions mention a command "fastboot flash userdata userdata.img", but there is no userdata.img file in their image files that they provide.

Sounds like the FlashAll.bat is hosed and not clearing your user partition. Don't use it. The fact that it's not overwriting the user data explains why it remembers your user data, and also why it's a bit borked after completing. Random bits of 1.5 settings are hanging around and confusing 1.3.
To recover, flash them manually one at a time, like this, in this exact order:
fastboot flash recovery recovery.img
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash userdata userdata.img
fastboot flash staging blob
Meanwhile I'm having my own fun fiasco, having taken advice that it was safe to flash the ROW LTE image on a US Device. Messed up my baseband in the process, apparently...

Thanks. I found out there's no longer any userdata.img in the Nvidia Shield K1 official images, so I have to do an extra step of doing the factory reset/wipe data procedure on my tablet first, and then image it.
Good luck with the phone
I am at basically the same spot on my Shield K1 Nougat in that in ADB Fastboot cmd line: adb devices and get nothing, neither in recovery mode or fully booted Android with MTP USB mode selected. The device isn't detected at all in Device Manager in any of the usual spots, and doesn't repopulate the list when unplugged/plugged back in.

LG Urbane 2nd Edition Verizon W200V , Android Wear 2.0 Side load OTA Guide

Hey All,
This is my first ever post on XDA ,So forgive me if I have not done a good job. I will try my best to provide sufficient details on how to upgrade LG urbane 2nd Edition Verizon model watch to Android wear 2.0 from Android wear 1.5
Known Issues : **********Android Pay is not working as reported by few users ***********
YOU FLASH THESE FILES AT THE RISK OF BRICKING YOUR DEVICE. I AM SIMPLY PROVIDING THEM AND BEAR NO RESPONSIBILITY FOR ANY SUBSEQUENT DAMAGE FROM FLASHING THESE FILES. ALL DATA ON THE PHONE WILL BE ERASED.
Prerequisites:
[*]LG Urbane 2nd Edition Verizon Model (W200V) for all other model you should have received a OTA by now , Please check OTA software updates on you watch.
[*]ADB tools ( Minimal is also sufficient) google for files and install in your computer , in my case I did it in "C:\adb".
[*]twrp-3.1.1.0 (twrp-3.1.1.0.img) recovery Image Copy of the file :- https://drive.google.com/drive/folders/0Bzk4DPXefDhrRzl3ckh6Uzhad1k
[*]Android Wear 2.0 OTA udpate Copy of the file :- [*]Modified file link http://www.filehosting.org/file/details/699795/lg2.zip or original file https://android.googleapis.com/pack.../af88cfbc96ad65e7b728e27c2decbdc6fb0e08e8.zip
[*]notepad++ (to edit updater-script), You can use Notepad as well.
1)perform factory reset on your watch just to be on safer side.
**update** Few users have reported that they have faced error while flashing due to buggy USB cable and they could successfully overcome the error by holding the cable to the watch and making sure the cable is fully in contact with the watch while flashing .**Update**
2)now we need to modify the OTA update file to work with Verizon model W200V ( skip this step if you have downloaded modified zip file and jump to 3rd step)
unzip the 'af88cfbc96ad65e7b728e27c2decbdc6fb0e08e8.zip" downloaded earlier and Browse the folder Edit file (updater-script) the file can be fount in the below path in my case."C:\ADB\af88cfbc96ad65e7b728e27c2decbdc6fb0e08e8\META-INF\com\google\android\updater-script". Use Notepad ++ and open the file and Remove 2 first rows,The file should start from "ui_print...", I used Note++ to edit the file and saved, as mentioned earlier you can use notepad as well.
Now Zip All files And name LG2.zip(Note : don't put all the files into a single folder and then zip, The zip should contain "META-INF" and other files) and place it in "C:\ADB\LG2.zip" for easier navigation in Cmd. (this file can be downloaded using above link Modified file")
3)next Connect your LG Urbane 2nd Edition watch to Computer and Enable ADB Debugging On watch (Settings-About-Tap about 8 times on "Build Number" and now go back to Setting and scroll down you should see new options "Developer Options" , Tap on "Developer Options" - and "ADB Debugging" select "Enable always from this computer" or something like that !!)
4)Now Check if your device has a connection to your computer using ADB tools
now on your computer under "Run" , type Cmd, this will bring windows command prompt.
Open Cmd in Windows and browse to ADB tools folder in my case I have placed ADB tools and all required files under "C:\abd"
Type "adb devices"
your device should show up under "List of devices attached"
Once device is found by computer we have to push the TWRP recover image to phone , To make life easy , I have downloaded all the above mentioned files to "C:\adb" folder
"adb push twrp-3.1.1.0 /sdcard/"
later boot into bootloader
"adb reboot bootloader"
Unlock bootloader
"fastboot oem unlock"
5)Now flash TWRP recovery (because we will be changing/modifying the original the OTA update file, stock recovery will fail to verify signature)
"fastboot flash recovery twrp-3.1.1.0.img"
boot to recovery to perform OTA side load
"fastboot reboot recovery"
Now you should see TWRP recovery welcome page,Allow read and write partition permission in TWRP.
6)now on your phone you should be in TWRP Main screen , press Install and you will find option to adb Sideload select that option and you will be presented with a option to wipe Dalvik and Wipe Cache , Select that and now go back to your cmd and type below code.
"adb sideload lg2.zip"
Now sit back and relax , The system will starts loading Android Wear2.0 to your verizon LG urbane 2nd edition watch (W200V) and once the process is finished , reboot to system.
1st boot will take some time , Have patience !! after all you have done ever thing right till now. (approx 5-10 mins, sometimes 15 mins)
Now your watch has Android wear 2.0 , enjoy.
Initially it might feel the OS is slow but allow the OS to settle down after that its snappy and the battery backup is also good in my opinion.
If you want to restore Stock recovery image just in case if you don't like TWRP, then
download the below targz file and extrat recovery.img file , LG Urbane 2 stock recovery image.
Link ,
enable ADB options under settings similar what we performed earlier.
1) Boot into bootloader
"adb reboot bootloader"
Stock Android wear 1.5 for LG Urbane 2nd Edition LTE(extract the file and copy recovery.img file to your folder , https://storage.googleapis.com/andr...wear-preview/nemo-mfd18l-factory-3faf6f2d.tgz (The file extension is */tgz(targz) , use 7zip application to extract the files and you will see recovery.img file .
Place a copy of recovery.img in "C:\adb\recovery.img"
"fastboot flash recovery recovery.img"
You can also Lock Bootloader to avoid the Notification at each boot.
"fastboot oem lock"
To get back to original android watch wear 1.5
if you don't like Android wear 2.0 use the below link and follow instruction to revert back to Android wear 1.5.
Stock Android wear 1.5 for LG Urbane 2nd Edition LTE , https://storage.googleapis.com/andr...wear-preview/nemo-mfd18l-factory-3faf6f2d.tgz (The file extension is */tgz(targz) , use 7zip application to extract the files.
Extract the *.tgz(targz) into your folder ("C:\adb")
Perform a "fastboot oem unlock", then run "flash-all.bat". Afterwards, you can "fastboot oem lock". This should restore you back to 1.5, where you need to take 1 OTA (from June 2016 Patch to December 2016 Patch).
Thanks All,
Missed something
Tried a thousand times. Not working **update** Looks like maybe It was just a buggy USB. I held it to the watch while flashing and it finally worked! I'm curious to hear anyone else's experiences with this cause it seems buggy but what would you expect? My apologies ty!
Has anyone other than the original poster tried this guide and been successful?

Ty! I think my USB connector is just a bit jinky.
I'm going to give this a try soon, everything working like lte, messages+, and phone?
Almost got it working
Followed all the directions and all seemed to work ok without errors. However, on startup now the watch is stuck on the startup splash screen (the animated google logo, has stayed there for hours). Can still access fastboot but unable to connect via ADB since the OS is not starting fully.
I also tried to restore back to 1.5 but since i can only access fastboot, my only option is to sideload but wont work with the TGZ link above.
Anyone have any ideas? or the zip file I could use to sideload the stock Wear1.5?
Thanks
Just making sure !! Try force restarting the watch by holding power button.
Did you reset the watch before sideloading ?
On android wear 1.5 use 7zip and unzip the tgz file and browse the folder till you see flashall bat file and run the same in bootloader. I have tried it and it works. Let us know if your still facing issues.
Locked /data won't allow sideload.
Hi, I've installed twrp, but it fails to sideload LG2.zip as the /data can't be mounted as it is encrypted. The TWRP doesn't have a format option for the /data partition so I can't reformat it to delete the encryption. So I'm stuck in TWRP.

I had similar issue initially , had to restore back to 1.5 and then clean all the data and then sideload 2.0 back. Try that and let us know if that worked.
You are the man! That worked
Installed recovery.img bootloader, then ran the 1.5 bat file, then reinstalled twrp. /data unlocked and mounted, sideloaded 2.0. You turned my brick back into a watch. Thank you very much.

Just making sure !! Try force restarting the watch by holding power button.
Did you reset the watch before sideloading ?
On android wear 1.5 use 7zip and unzip the tgz file and browse the folder till you see flashall bat file and run the same in bootloader. I have tried it and it works. Let us know if your still facing issues.

Thanks.
I made sure to reset before force restart and reset before sideloading. Still having some trouble with the 1.5 reset though.
In bootloader, which option to I select for flashall to work? ADB Devices can't see it and if i just run from bootloader home screen i get , <waiting for any device>. Same thing in TWRP.
Thanks again for your help
[Note for other users unfamiliar with this process & having similar problems - you'll have to unzip the source file, then unzip "output" to extract all the files... tooke me a few attempts to realize i missed a step!]

As with some other users the cable connection seemed to be causeing me some problems. I used a different USB port and held the connector against the watch and flashing to 1.5 worked this time.

Flash the original recovery.img extracted from the .tgz file and try again it should work.
For ADB access in TWRP use sideload using ADB option .
So will android pay work now with this

I think I am having the same issue as you. I was sideloading 2.0 as instructed and I think I had a bad cable connection. I am now stuck with no wear operating system at all. When I start my phone it only stays on LG boot screen with the unlock icon on the bottom. My computer is now unable to recognize the device because I cannot get into settings to turn on ADB Debugging. If I follow the same steps as you can I sideload wear 1.5 and update via boot loader screen?

How to unroot, lock bootloader and go back to stock?

For background, I have Verizon pixel 2 and am using a Mac.
I went down a massive rabbit hole last night reading through these forums and all the posts and was able to unlock bootloader, flash the January OTA and then root by doing the modified boot file with magisk. (interestingly enough the booting into recovery gives me red ! Over a dead Android and I could not load the OTA that way, nor did the adb sideload OTA comand work either, I had to push the extracted walleye img and then the zip file as discussed in one of the steps in some other thread here)
So anywho, in the end I now have a phone that gives me 2 errors when it reboots, one for unlocked bootloader and another for root telling me something is wrong with my phone and i should contact the manufacturer (which I read on here is normal), but my biggest issue is that my ADT alarm app doesn't work anymore (even if i check it off for hide in magisk). I feel like the root is just not worth it for me and I want to revert to completely stock image, even if it resets my phone and I have to re back everything up all over again like did when i had to do the unlocking of the boot loader.
So -- What are the steps I should take?
1)uninstall magisk from magisk manager?
2)delete magisk manager?
The above will unroot me, correct?
3)Do I push the stock boot image file onto the phone?
4) do I have to repush the latest OTA walleye image and zip file onto the phone again?
5) do I then do the adb reboot and do the flashing lock command (same command i did to unlock the boot loader) to lock up the bootloader and reset to stock?
If someone could be as explicit as possible in correctiong or validating my steps above it would be much, much appreciated.
I don't want to do any more unnecessary steps in flashing things than is needed so if I have extra steps above (perhaps 4 is not needed?) Let me know.
Thanks
Proceed with Caution
I am not an expert by any means, but can speak from personal experience. I was in the exact same situation as you. I followed the detailed steps to unlock the bootloader on my pixel 2, received similar issues, and the same prompt when the phone rebooted. All that to say proceed with caution.
My thoughts on questions 1 & 2: I personally wouldn't recommend you remove or delete magisk from the manager. When I did i had to reinstall it via twrp. My phone functioned fine, apart from the error at reboot.
My thoughts on questions 3 -5: When I followed the steps on XDA for your questions here I ended up bricking my Pixel 2 with locked bootloader from Verizon. Probably an error on my part, but wouldn't want someone else to go through the headache, hours of issues, and then an expensive paper weight.
My suggestion would be to:
1. Leave your phone as is and attempt to trouble shoot the app or apps you are having issue with
2. contact Google support on your phone and see if they would replace it
3. wait for an established method to unroot the pixel 2 here
Thankfully Google replaced my phone due to the error after rebooting, prior to me bricking it. I knew I had a replacement phone coming. So I attempted to go back to stock and that is when I messed it up.
Note sure this is exactly what you were looking for, but hope this helps you.
Dozens of posts with hundreds of pages on how to root but no advice on how to go back to stock cleanly?

Your version is Verizon which is making things more complicated. Generally when the bootloader is unlocked, you just hit flash-all.bat and then relock the phone. Given that the Verizon I'm not sure.
So you are on stock ROM with all these apks loaded ? If you go to settings, then do a factory data reset, you'll reset the phone back to stock and completely wipe the phone and return it to stock, at that point you can go into bootloader mode and relock.
Again your bootloader is unlocked, so the flash-all is your best option. If you see the red exclamation point with the error android laying on his back, you press power and up volume and toggle that and it will bring in the stock recovery which you can sideload the OTA however it may fail since you have magisk.
I bought my phone stock last year and have not rooted it or modified it in anyway. Too many problems and it only gets harder and harder as Google releases a new phone.
@mikeprius -- thank you for replying. after reading more on here, it seems like that's the way to go -- flash-all script, seems like i don't really need to do 1&2 that i wrote above as the flash-all will wipe that out by itself.
at that point i should be running the latest stock 8.1 but with an unlocked bootloader (and according boot up message screen) and i should be able to re-do the fastbook unlocking command to lock the phone back up.
(and yes, after reading even more now -- and i tried this yesterday -- i completely missed the portion about PWR + Vol Up button, that's why i think i had that issue, but still, i was able to push the update by pushing img and then the zip through).

If I were in your situation and the bootloader is unlocked, just use flash-all which has a wipe script then call it a day. I think trying to screw around even more is just a waste of time and I wouldn't even bother with the OTA, just erase and flash stock. You don't have to relock your bootloader if you don't want to, if you stay fully stock you may still be able to get OTA updates. I'm not sure if a bootloader locked is required someone can chime in as it has been awhile since I've done this, but over 1 yr ago, I just kept the bootloader unlocked, kept things stock and everything was good to go. Obviously there are security issues with an unlocked bootloader, but I'm sure you know this already
@mikeprius you keep saying reset/erase, do you suggest i re-set the phone and then flash the stock image?
i was just going to flash the stock image, i figured it already wipes the phone, and locking the bootloader would wipe it again, so what's the point of erasing all data prior?
Not to hijack this thread, but a question to add... I thought that there were kernels that would mask certain things to allow all of those apps to work, and get rid of the "problem with device" message.
Is that correct?

Just flash the stock images. It will auto reset.
Again, don't mess with anything just flash stock images, then go from there.
Also flash the newest version of the stock images out there. The pixel 2 will error if you try to downgrade any version.
here are all the steps to UNROOT and LOCK the boot loader on your Pixel 2 on a Mac (windblows users simply ignore all the "./" references).
1) download the latest ADB tools from google
2) download the latest factory Walleye image
3) unzip files from 1&2 into a common directory
4) edit flash-all.sh file and add "./" infront of every instance of "fastboot" in the script [windows users ignore this step]
5)hook up your phone to your computer in debug and file transfer mode. check that "./adb devices" loads your devide
6)type " ./adb reboot bootloader"
7) check that your device is still connected by typing "./fastboot devices"
8) type "./flash-all.sh"
===the script will run and your phone will be restored to stock, and UNROOTED. upon boot up skip through all of the setup steps and get to the phone settings as fast as you can. enable developer option, enable debug mode, set phone to data transfer ====
9) check that your phone is connect to your computer by "./adb devices"
10) type "./adb reboot bootloader"
11) check your devices is still connected by "./fastboot devices"
12) type "./fastboot flashing lock"
===== this will re-wipe your device again, you'll see the circle of death, and this will LOCK your boot loader back up again======
side note, feel free to skip over the steps where you check that your phone is still connected to the computer (./fastboot devices) if you're less paranoid and comfortable.

hey there. what is the command suppose to look like? every combination I try gives me an error:
first, I don't even enter the Fastboot command the same wayit given me an error:
Asads-MacBook:~ asad$ ./fastboot devices
-bash: ./fastboot: No such file or directory
so I try this: Asads-MacBook:~ asad$ fastboot devices
[serial #] fastboot
these are all the errors I get:
Asads-MacBook:~ asad$ cd /Users/asad/Desktop/walleye-opm1.171019.021
Asads-MacBook:walleye-opm1.171019.021 asad$ ./flash-all.sh
./flash-all.sh: line 21: fastboot./: No such file or directory
...
Asads-MacBook:walleye-opm1.171019.021 asad$ ./flash-all.sh
./flash-all.sh: line 21: ./fastboot: No such file or directory
...
Asads-MacBook:walleye-opm1.171019.021 asad$ ./flash-all.sh
fastboot: usage: unknown command ./flash
...
Asads-MacBook:walleye-opm1.171019.021 asad$ ./flash-all.sh
./flash-all.sh: line 21: fastboot./: No such file or directory
...
how is the command suppose to look that I can edit it the right way?
"fastboot: No such file or directory" means that you didn't do step 1, step 3 on the file you didn't download, and there should probably be a "cd /<whatever the 'common directory'>" is. (I just created a directory named adb. That's good enough for me to know what it's for.)
You have to download adb and fastboot (which come in the adb tools file), unzip them to whatever directory you're going to use for flashing the phone, and cd to that directory.
Then, since you're evidently on MacOS, each command has to have ./ in front of it (that says "the current directory"). Try all that, then see what happens.

yayy! that worked!
so i had adb and fastboot in a folder (platform-tools) and i had the factory image in its own seperate folder (walleye-files). i was making the cd; walleye folder and trying to flash-all.sh there.
so i had to put the files from the walleye folder into the platform-tools folder. Then I made platform-tools the cd. now when . i could now follow all the steps from 4-12 and got the pixel 2 the way it was OTB.
thanks!
Great! I'm not a Mac expert (last time I used one was the 128K Mac in 1985), so I'm not sure how to export a path in MacOs, so I gave you the complicated way, but you got it done anyway. (If you ever find out how to add the platform-tools folder to your path, you can leave adb and fastboot in there and keep the ROMs [walleye] in their own folder, cd to it and adb and fastboot will still work.)
