Hi after reading through the post on GitHub on how to simply root your shield I have a few questions that the tutorial doesn't make clear:
1)There are a ton of files at the top and not sure what to do with them...
2) There is a bit where it explains "On your computer, navigate into the directory containing this file and enter the following command:
fastboot boot zImage_dtb ramfs.img.gz"
But it doesn't say that after you open the directory what you do with it?
Do you keep the window open and that's fine?
Do you type in it's location into command prompt before you type in: fastboot boot zImage_dtb ramfs.img.gz?
Just a bit confused as to what all the files are and where I put them and how they have to be utilised etc
Just need clarification for peace of mind
wanted to post the link but forum won't let me yet
Root explanation
Hi here is the main walkthrough from github but as I said there are a few plot holes for people who are new.
If your SHIELD is already unlocked, you can skip this section.
SHIELD ships with an unlockable bootloader. The bootloader is locked by default, which prevents anyone (including yourself) from booting custom OSes and changing system partitions to potentially obtain extra privileges. This is a significant security feature: in the event that your device gets stolen, an attacker will not be able to retrieve your personal data or use your device if your lock screen has a password set.
By unlocking the bootloader, you allow anyone with physical access to your SHIELD to boot custom images and flash system partitions. This opens the way for an attacker to access your personal information or physically damage your device. For this reason, unlocking the bootloader will erase all your personal data like a factory reset does (so a potential thief cannot get it) and will also void your warranty.
If you know you really, really want to take these risks, here is how you unlock SHIELD's bootloader.
Switch your SHIELD off (long press the NVIDIA logo button and select Power off).
Power your SHIELD on while maintaining the back and home buttons pressed (these are the two buttons that lie under the big NVIDIA-logo button, on its left and right). Release them once you see the bootloader screen.
Connect your SHIELD to your computer using a USB cable.
On your computer, enter the following command:
fastboot oem unlock
This will display the unlock menu. Read the disclaimer and think one last time about what you are doing. This is your last chance to stop.
Use the back and home buttons to select your option. If you decide to continue, select Unlock and press the NVIDIA-logo button to validate. Your personal data will be erased and your device marked as warranty-void permanently.
Regardless of your choice, you will be back to the bootloader screen. Using the same buttons, navigate to Poweroff and select this to power your SHIELD off.
Rooting SHIELD
Now your bootloader is unlocked, but you still don't have root access. For this, we need to install SuperSU, and we will do so by booting a custom Linux image that will do this for us.
Power your SHIELD on while maintaining the back and home buttons pressed (these are the two buttons that lie under the big NVIDIA-logo button, on its left and right). Release them once you see the bootloader screen.
Connect your SHIELD to your computer using a USB cable
On your computer, navigate into the directory containing this file and enter the following command:
fastboot boot zImage_dtb ramfs.img.gz
The kernel and ramdisk will be downloaded and started. You will see 4 penguins on your screen, and the message ROOTING SHIELD will appear. Shortly after, your device will reboot. Congratulations, you are rooted!
For some unknown reason USB debugging in Developer options might become unchecked after rooting. You will need to re-check it if you want to use ADB.
It is safe to perform the rooting operation as many times as you want (e.g. after an OTA). Your user data will not be erased by rooting itself, it is the act of unlocking the bootloader that does.
Is there anyone who can add a little to this to make it more simple for a noob like me?
I understand there is a file set that is at the top of the page and I downloaded the files which include zImage_dtb ramfs.img.gz
but don't know how to utilise them etc
There are no videos on youtube of how to do it and if anyone can add just a few more steps so that I know where I'm going with this (don't want to brick my system).
I just want controller support installed like Tincore or gamekeyboard so I can unlock the potential of the games library on GooglePlay.
Thanks for reading.
you copy those two files "zImage_dtb" & "ramfs.img.gz" to the same directory your adb and fastboot executeables are (same directory you issued the oem unlock command from)
then navigate to the same directory you did the oem unlock from via command line then issue the command "fastboot boot zImage_dtb ramfs.img.gz"
it's pretty simple but I can run you through a simple example of what I did
1)download android sdk
2)copy platform tools folder to a directory on c drive (exp c:\tools\ )
3)copy the 2 files above to the same folder along with cwm recovery(optional)
4)boot shield into fastboot mode (home+back+power)
5)navigate to the folder with adb, fastboot, and the above files in it.
Code:
cd c:\tools
6)detect if fastboot driver is installed with "fastboot devices" if result, then continue, if no result, then check if correct driver and check connection
7)issue oem unlock command and follow the onscreen prompts
Code:
fastboot oem unlock
8)restart device, after a full boot cycle(wipes data), power back into fastboot
9)issue the "rooting image" command, device with automatically reboot
Code:
fastboot boot zImage_dtb ramfs.img.gz
*10) optionally reboot back into fastboot and install cwm recovery
Code:
fastboot flash recovery recovery.img
pretty simple
thanks for fast reply.
Ok so I have Two different versions of Android SDK (32 bit and 64 bit) which one do I use?
"copy platform tools to a directory on C drive (exp C:\TOOLS\)"
What are platform tools?
"copy the two files above to the same folder along with cwm recovery"
What two files? do you mean the zImage_dtb and ramfs.img.gz? Do they go into the C:\TOOLS\ folder?
"navigate to the folder with adb, fastboot, and the above files in it"
What do you mean by navigate? Do you simply mean open the folder or do I use a program to do this?
"Detect if fastboot driver is installed with "fastboot devices" if result, then continue, if no result, then check if correct driver and check connection"
What's fastboot devices? What does result and no result mean? What does Check driver and check connection mean? how dod I do that?
I'm confused by all the lingo, what applications I should be using and when exactly do I start using command lines etc
Thanks for help so far been great but I need step by step instructions eg
open folder, copy and paste file1 and file 2 to this folder
open application X
click import file 1 and file 2
type XXXXXX\root\cdrive into command
press enter
see?
I do not know what some of the words mean and how to do some of the stuff the tutorial says. It's jargon and I have all these files, in all these folders with no idea how to do this from start to finish.
Appreciate the help so far but you are dealing with a novice. I know the work won't take long but I need all the relevant info, in one list, with consistent language to ensure I do everything as it should be done.
Bless you sir and...
Good luck
If your confused by my instructions you need to wait for a "one click" installer, sorry.

Step by step instructions like that would take quite a long time to write. Its basically assumed that navigate is a straight forward instruction, namely, open My Computer, click C:\, click something else, etc etc. 32 bit vs 64 bit, again, you should know what your computer is running and use the correct one respectively.
The reason they dont issue novice instructions is for 1 reason only. People who such as yourself claim to not understand the "jargon" are also those who are more likely to make a mistake when rooting. This can lead to a completely bricked device, ie one that will no longer turn on and load up android, totally dead device. As far as the manufacturer is concerned, a bricked device unless bricked by one of their own updates on a non rooted shield installed correctly, is not covered by warranty. This leads said novice to accuse the tutorial writer of having something wrong in the tutorial when in reality they have clicked the wrong thing etc.
Either way, end result: dead device.
Rooting is not aimed at the novice. It is aimed at the advanced user.
Thank you
I understand that and appreciate the explanation. I can work my laptop and I know that my laptop is 32bit or 64bit but it did not say at any point that it was referring to my computer. It just said download the 32 or 64 bit version. Well I have to make sure what they are talking about before I go and try to root my device as I like clarification on everything I do so that I get it right (and don't brick it). At the moment the explanations are all over the place, some info here, another bit there and was hoping somebody could link it all for me and make sense of the order in which I would do things. I have installed graphic cards in my laptop, put custom firmware on to ipods, psp's, computer etc but this is my first foray into android territory and would like to get it right. I am trying to follow a video tutorial but my computer's reaction to driver updates for the ADB/Fastboot drivers is telling me my drivers are up to date and I'm not getting the error message his is. This means I'm not sure where to go as the situation is diffferent s He is trying to get motochopper working for shield so it will root the device and hoped it would do the same for me.
Hopefully some clarification will come sooner rather than later but won't venture fourth until I'm absolutely sure of what needs to be done.
Again, thanks for the help it is appreciated.:laugh:
Sorry for being so abrupt, it wasn't my intension, you are trying to learn. I will not give a step by step which I feel would be the best, yet potentially more dangerous option for you though.
The parts written in the "code" blocks are what you copy and paste into the command line. When I say navigate I mean by changing directory via command line. You can copy files with a graphical file manager as it's quicker but navigate could also mean graphically.
Google search how to tell if you are running 32 or 64 bit windows, there are better guides and videos than I would be able to describe in a few lines. I was assuming you had already unlocked your bootloader as it is required before root, I covered it as point of reference only.
Platform tools is a folder in the SDK, if you install the SDK you will see that folder where you install it.
Fastboot is the utility also in the SDK that you run from command line that's in the code blocks I posted. If you run the command it will either give a result saying a device is detected or it won't show anything (no result) and you have an issue. If you have a driver issue then that's a whole other problem with a specific forum topic for, but I also assumed you unlocked your bootloader which would require you have fastboot and driver issue resolved.
Main cause of my snappiness is it says the requirement (first line of what you quoted) is unlocked bootloader and you are asking questions about rooting (step two after unlocking bootloader) didn't realize you were stuck in step 0, trying to figure out where to start.

Download 64 bit software for 64 bit windows and 32 bit on 32 bit windows. Only notable exceptions are where a guide explicitly says to get 32 bit for some particular reason (in my case the only time I have come across this is MSI afterburners screen recording facilities only functioning on a 32 bit program for some reason, no 64 bit version) or if you are running 32 bit windows and physically cannot run 64 bit software even though a guide says "use 64 bit java etc etc".
rather interested in installing a graphics card in a laptop seeming as laptops use graphics cards that are soldered down to the motherboard not on a seperate removable card in all with very few (but existant) exceptions.... I think asus, dell and someone else did offer them at one point, its actually what the MXM connector was invented for (but its used for a few other things now instead).
Anyway. Its always good to have clarification. I think the post above me gives a few starting points and as always: google is your friend (so are bing and yahoo, but they are those friends where once you leave your job or school or whatever you probably wont ever see again).
boot achieved
I boot loaded the Shield through dab and boot loader.
Shield restarted once I chose to unlock the shield. I lost all my stuff (as expected) and it restarted. The drivers then reinstalled on my laptop.
I restarted my laptop and the shield again and tried to reinstall the drivers that were made for the ADB but sadly I get this message now...
"Windows has determined that your driver software is up to date MTP USB DEVICE"
So I restarted everything and the device is now showing up in the Andriod Device driver list.
I am using minimal adb and Fastboot application. It opens the command menu
I type in
adb reboot bootloader and I get the reply "error:device not found"
any ideas?
Sigh!

So the shield is now showing up in my computer manager under Portable Devices and not under the Android Devices like it did when I installed the custom drivers the first time.
Will this be an issue when I come to root?
Sigh!

the MTP driver is for plugging the shield in and viewing the file system. If the device isn't under android devices in device manager then you may need to reinstall the ADB drivers or just double check that the ADB can see the device (it may).
Open a command prompt. type "cd [path to the android sdk]\platform-tools"
Then type "adb devices".
It should list all the android devices it can make a debug connection to. If the Shield is in that list your good, otherwise don't proceed any further until you can rectify that.
The other solution is that you dont need ADB drivers on a linux system for some reason. Don't ask why. I havent a clue. But that would necessitate installing linux.
And something that is useful for finding the adb on the command line again in future for windows. You don't want to "cd" into the correct folder every time (the command line equivalent of opening folders). Sometimes you just want to be able to open the command prompt, type "adb devices" and it to just work. That's doable by altering your system PATH variable.
Open my computer. Right click > Properties, should open the System window.
Left side there should be a button saying "Advanced system settings".
It will open the "System Properties" window to the "Advanced" tab (if it isnt on that tab just switch).
Bottom of the window should be a button saying "Environment Variables...". Click it.
Now the window that appears will be split in 2. User variables and System variables. There is a PATH entry in both, it is best that you only change 1. If you are the only user or you only want your user to be able to access the adb, you can change the User variable. Otherwise you can change the system variable for the adb to work on all users. For me I had to add python to my path once but I wanted to do this for all users so I changed the system one, the PSP SDK I installed however altered the User variable by default. Make your choice and find the variable "PATH" in either one.
Click Edit. A window will appear with Variable name and Variable Value. At this point what I recommend doing is copying the entire contents of value into a notepad file and saving them as a backup. Then cancel and go back into it.
Code:
C:\Program Files (x86)\Intel\iCLS Client\;C:\Program Files\Intel\iCLS Client\;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;C:\Program Files (x86)\Windows Live\Shared;C:\Program Files (x86)\Intel\OpenCL SDK\2.0\bin\x86;C:\Program Files (x86)\Intel\OpenCL SDK\2.0\bin\x64;C:\Program Files\Intel\Intel(R) Management Engine Components\DAL;C:\Program Files\Intel\Intel(R) Management Engine Components\IPT;C:\Program Files (x86)\Intel\Intel(R) Management Engine Components\DAL;C:\Program Files (x86)\Intel\Intel(R) Management Engine Components\IPT;C:\Program Files (x86)\Lua\5.1;C:\Program Files (x86)\Lua\5.1\clibs;C:\Python27;c:\Program Files (x86)\Microsoft SQL Server\100\Tools\Binn\;c:\Program Files\Microsoft SQL Server\100\Tools\Binn\;c:\Program Files\Microsoft SQL Server\100\DTS\Binn\
That is my Path variable.If you look the path variable is mostly a series of filepaths (or other variables too) which are seperated with ";". When you type a command such as "adb" into a command prompt what windows does is searches the current command prompt directory for a file it can execute which is called "adb" (it ignores extensions unless explicitly given one), if it doesnt find it in the current directory it searches each folder in the system path variable for the same executable (it ignores sub directories, it will only search the folders above on my system). So if we want to be able to type adb from any folder, we need the folder the adb is in to be added to the system path variable.
Simply add this to the end of it
Code:
;[whatever the path to the adb folder on your system is]
It will be whatever you had to add after "cd" to get to the adb earlier (must not leave out the C:\Users etc etc if its stored in your documents, cd will let you get away with ignoring that, the variable requires the FULL filepath).
Save the variable. Open a command prompt. Type adb, should work. If not, QUICKLY RESTORE THE BACKUP BEFORE WORKING OUT WHAT WENT WRONG. Should be safe with the broken variable to be fair, but you don't want to risk anything. If you dont think your going to use the adb often then simply dont bother updating the path variable rather than taking the (minimal) risk.
Wow my path variable is beginning to get a bit long now I only manually added python and lua to it. The rest will be the default entries and the SQL server stuff appears to be from installing visual studio. Yours probably wont match.
hehe you're going to hit me in a minute...
message deleted as I was being a moron....
ok I should be entirely clear as you guys are trying to help
ok I should be entirely clear as you guys are trying to help me so it's best i let you know what I have done up until this point.
Ok so I boot loader my shield.
I downloaded minimal ADB and Fastboot. I also downloaded the drivers you recommended in the forum.
I installed the drivers:
My shield showed up in the computer Manage list as a Portable device.
I chose to install the new drivers, it asked if I still wanted to go ahead as the drivers could not be verified and I said yes.
The drivers installed and the Shield changed from being in the portable list to showing up as an Android device.
Success I believe.
I then opened ADB BOOTLOADER and booted my Shield Manually.
I then typed in the relevant prompts in the command and a list of options showed up on the shield.
It showed my device number in the command prompt which was the one on my shield screen.
I then command the unlock function and the shield offered me the option to lock or unlock.
I chose Unlock and it then rebooted.
When it restarted, my computer reinstalled the device drivers and my shield had reset to factory settings (as it should).
I then looked in the Computer Manage list and my Shield had reverted back to being in the Portable Devices list.
I restarted both again and the Shield then showed up under Android Devices like it did when I installed the custom drivers the first time.
But the name of the device is Nvidia Shield - not Nvidia Shield ADB like in the tutorial video... not sure it that helps.
I enabled USB Debugging,
put the Superuser.apk and Su bin file into the minimal AADB and Bootloader folder.
I then put the Thor-insecure-boot.img in the Minimal ADB and Bootloader folder too.
I started up the command prompt from the minimal ADB and Bootloader.
I then saw this
C:\Program files <X86>\Minimal ADB and Fastboot>
I then typed in adb reboot boot loader and pressed enter
I got
error: device not found
So I decided to take the above advice and opened a command prompt
I typed in cd C:\tools\adt-bundle-windows-x86_64-20130729\sdk\platform-tools
and pressed enter:
It repeated what I typed and I then put in adb devices.
It then came back with:
List of Devices attached
but nothing was listed....
doh!
Progress!
Ok so I uninstalled my drivers to start again, plugged in the shield and it reinstalled my drivers and now under Android Devices it shows NVIDIA SHIELD ADB
Result!
Now I opened the dab cmd prompt
typed in
adb reboot fastboot
and it booted my shield! jolly good
But then I typed in
fastboot boot thor-insecure-boot.img
I then had
<waiting for device>
show up in the command window.
This is where it stayed.
On the screen of my shield I have options:
continue
restart bootloader
recovery mode
poweroff
Do I have to choose one of these in order for it to begin the thor img command?
C:\tools\adt-bundle-windows-x86_64-20130729\sdk\platform-tools Just incase you didnt get it earlier. That would be the path required for the variable change above. Just whack a ; on the end of the existing variable and throw that new path on the end and done.
But yes, adb devices not listing shield is not a good thing. Try reinstalling the ADB driver for the shield manually (you cant do it via device manager etc).
cool
I'm past that and now <waiting for device> problem to rectify. Am looking online now but there isn't much on there so far...
looking under device manager it shows up under Android Device as Nvidia Shield ADB but it also shows up under portable devices as SHIELD.
Whilst in boot mode the device only shows up in portable devices with a exclamation mark next to the device.
*UPDATE*
I uninstalled the portable device driver because I think it may have been causing confusion.
I then typed adb devices into CMD and a list of devices showed the serial number of the nvidia Shield.
I then typed in adb reboot bootloader in and it booted.
I then tried adb devices again and nothing showed up.
When I go into bootloader The Android Device: Nvidia Shield ADB driver disappears in manager once I go into bootloader mode. Is this normal?
Hmmmmmmm
definetly something to do with the drivers.
I'm on windows 7 64bit by the way.
Going back into device manager I noticed that there is another device under Other devices, upon looking at it it is Fastboot and has an exclamation mark in a yellow triangle next to it (Minimal dab and fast boot is open though).
Such a bummer as I'm so close yet so far
picture
ok so here is a pic of my devices list fastboot is there
before boot
This is the devices it can see before I put the shield in boot mode
devices seen after shielf in boot mode
the are the devices seen after I put the Shield in boot mode. It can't see any devices
waiting for devices
This is the screen on the shield in boot mode. The CMD screen says "Waiting for Devices"
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.

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
I've got reboot to boatloader on main page from stock recovery on my 6045k

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 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.

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?

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.
Hello guys,
I wiped my internal storage yesterday and I've lost all my images and files (I don't have any cloud of any type google drive etc)
I Still have a TWRP on my phone ...I don't want to install anything in it but to recover the files. f I install anything ....the files will be totally wiped because new files will be on their space.
a) Is there anyway that I can connect my phone to a PC (Windows/Linux) as a Mass Storage Device and do a low level scan on the internal memory (Because the phone connects only as MTP )
b) Is there a way to create a bit by bit image of what's inside the memory into an image file (Bin,ISO) and then check the file with recovering software on my pc
I've already tried Diskdigger and Dr.phone who didn't find a lot of photos (10 of 1000 that I used to have)
Please if anyone know a way... pleeeeeeease give me a clue/hand!
I know that the thing that I did was totally idiotic/silly ...so there is replying about that.
Thank you !

Mabye give that a try when you are familliar with the command line. Sounds quite well
https://dflund.se/~jokke/androidfilerecovery/
If you have root access or at least a recovery installed you can also try this:
I assume you use linux
1) you need adb installed on your pc. Using ubuntu 16.04 simply type in terminal
Code:
sudo apt install adb
or on an older version
Code:
sudo apt install android-tools-adb
2) Identify the partition where "your internal storage is"
Use
Code:
adb shell cat /proc/partitions
You will see a long list of partitions. In the third column you see the size of the partitions, the biggest one should be the internal storage. (in my case mmcblk0p28, but can be different)
3) Backup the partition to pc using the dd tool
Now run
Code:
adb shell su -c "dd if=/dev/block/<your-partition-name>" > storage.img
You won't see any progress bar, just wait until it's finished.
Now you should see a file called storage.img in your current working directory.
4) Simply mount the image on pc and use any recovery tool you want. (e.g. foremost or testdisk)

Hi there just show the reply...
Thank you very much for the reply....and that is the thing I did by the way...but apparently it wiped a lot of things in my phone (not only the initial sectors where all the names are kept) and I couldn't recover anything
Thank you though...
So I may be doing something totally idiotic, but I seem to be stuck at the most simple part of unlocking my bootloader.
I follow this to step 2:
https://www.xda-developers.com/unlock-bootloader-root-oneplus-7-pro/
when it says "Set up ADB" I follow the link to this:
https://www.xda-developers.com/install-adb-windows-macos-linux/
until I get to step 7. When I enter the command 'adb devices' I never get a serial number nor a prompt to allow or deny USB Debugging access. I never get see my device’s serial number in the command prompt.
So doing a bit of digging I have looked into ensuring my ADB and One Plus driver was installed correctly, and I even purchased a new data transfer cable to make sure that wasn't the issue.
I check my device drivers and see get an error in my ADB Interface driver, but after following a few tutorials I'm still lost as to whether its updated or if I'm doing so incorrectly, or if that's even the problem.
Any direction would be appreciated.
I am running Windows 8.1 and my device is Android 10, model GM1915.

Hallelujah!!
Finally found a way to manually install the correct driver from a tutorial on visualgbd{dot}com, so now my device is recognised.
I had to find where my drivers were being default downloaded since they weren't in the place the tutorial indicated, but that was the only hitch.
SO. On to the actual unlock. :fingers-crossed:
So I need help.
I followed an XDA video tutorial which was a bit difficult for a newbie, but I think I did everything correctly up to installing TWRP.
I got to the point of flashing my ROM and jumped to the Eelo website instructions:
- Go to main menu, then tap Wipe.
- Now tap Format Data and continue with the formatting process. This will remove encryption as well as delete all files stored on the internal storage.
- Return to the previous menu and tap Advanced Wipe.
- Select the Cache and System partitions to be wiped and then Swipe to Wipe.
- Sideload the /e/ .zip package:
- On the device, select “Advanced”, “ADB Sideload”, then swipe to begin sideload.
- On the host machine, sideload the package using: 'adb sideload filename.zip'
I followed this and while the package did not sideload, I beleive my recovery partition was wiped I seem to be stuck.
I'm at the point where I feel I need to Flash OEM Stock and start over, but I am getting a bootloader loop.
Really need help. I feel at this point I'm going to start making things worse as I look at various tutorials and whatnot.
In case additional information is helpful:
My device does not show up in my device list, but it is detected with "fastboot devices".
I attempted to flash TWRP with "fastboot flash boot <TWRP.img> and it writes to 'boot-a'. But when I then try to boot into recovery mode, instead of booting into TWRP I enter the fastboot screen.
I tried using mauronofrio's Tool All In One to flash stock ROM and possibly fix the partition, if thats what the problem is, but I cant tell it did anything.

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)...
C.Modica said:
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.
