it might be possible that this works for other firmwares too, please try and report back here thanks
Requirements
- a Linux distro (mine is Xubuntu 12.10, but should work on every Linux OS)
- a working and updated ADB (for installing ADB, search for tuts here on xda )

- and most important: a brain with the ability to read
The steps
1) charge your phone to 100%
2) connect your phone in LG software mode
3) if you have the path to your adb defined, then goto 3a). if not, then goto 3b)
3a) open a terminal and type
Code:
adb reboot oem-unlock

(if you've installed the android-sdk in your home directory under "android-sdk". if not, change it to the directory you've installed it)
then type
Code:
adb reboot oem-unlock
4) now you should see this on your phone:
do i wanna unlock it? of course i do so press the vol + button ATTENTION: there is no further warning, your whole /data/ partition will be formatted!!!
5) now you should see this, and your BL is unlocked and your /data/ partition is wiped
6) now pull out your usb cable and your battery, too
7) put your battery back in and boot
8) set up your system
9) now go to the hidden menu and check your BL status (dialer: 3845#*880# --> Bootloader Unlock Check --> Bootloader Unlock Check --> Unlock)
10) do the harlem shake and be happy about your unlocked BL
and please, don't post "thanks" if i've helped you, just hit the thanks button

Does it applies on 234 devices too? I ll not have access on a linux pc till monday!

Cool dude, thanks.
Do you think its possible to do this with those bootable Linux OS cd (so i dont have to install linux on my hd just for dooing that) ?
Do you loose the unlocked BL if you install another KDZ after the unlocking?

Someone know why not working on every windows?
I have the android sdk installed and the same procedure worked for me without linux.

hmmm, possible? maybe, but this would be extremely slow, cause you've gotta get adb working first and so on. so i'd say it won't work, but not sure.
but some distros have got the ability to install them as a "windows prog", this creates a virtual harddrive where linux can be booted from, so no need for reformatting the hdd just google about it
some users reported that it will not be lost after flashing a kdz. but also here: not sure, cause i haven't tried it myself yet (my BL is now unlocked for about 3h yet )

This "final" screen I can confirm on my 262-000 from Amazon. I used Windows and http://forum.xda-developers.com/attachment.php?attachmentid=1859693&d=1365149301 for the ADB driver but the same method. It takes like 2sec to do! I installed CWM etc. fine afterwards!! Thank you!

Security error
I don't get the screen like in 4)
I just get Security Error, any ideas?

Don't work with ADEUBK 262 000
I can only unlock with the china 20a.

This is not universal, seems with latest update LG showed some mercy on German users...rest can feel screwed all over again
F*ck you LG retards they are only good if Google screws them good, who's your papa :silly:

On 234 this didn't work with Linux and the leaked 20A.
I might try later to update the phone (GBR) with the official one but I wouldn't hold my breath.

I use euro-open.
If its driver related, which driver is needed?
I only know of the Google USB Driver for the Android Composite ADB Interface.

Thanks for the tutorial - but can you explain why is this just working on a Linux OS ? I mean what's the difference between trying to unlock the BL on a Win7/8 OS or a Linux OS ?

Sometimes is semi-bricked, specialy after the "morning-call empty"
Don't worry, re-flashing will solve the problem.

Hi Guys!
Android Commander is windows application to keep control on your android apps and files from PC. This is a small, very very fast and intuitive app.
If someone want to try it, go a head. But remember, you doing this on your own risk! I'm not professional programmer, this is only my hobby
Program Requirements
Before you install the program you should read this:
Phone Requirements:
- ADB ROOT Access
- BusyBox
- „Settings->Applications->Development->USB debugging” must be enabled
- USB Cable
Computer Requirements:
- Windows XP/Vista/7
- ADB USB Driver
- Java JDK
- Minimum 800×600 screen resolution

Ok, first off I start the app thinking it was an installer. Tells me no device is connected.
I assume the the app is now shut off since there is no indication of it running.
I plug in my phone and turn on debugging and then I get a window that says
'adb' is not a valid integer value. Then something about my adb server is out of date. Beats me what this supposed to mean.
I attempt to click the X on the warning message and it keeps poping up. So I used task manager to kill it.
WindowsXp SP3.
DroidExplorer works
Out of all seriousness I like your slim and mean approach. Just doesn't seem to work on my machine.
looks like I need a newer SDK

I had issues like this with old SDK, try to install 1.6r4.
Seems to work fine for me (wit the latest sdk)
thanks for the app, will make things a little easier for me during fresh flash's

You get this message if you have an adb server running (like from droid explorer) that is a different version then you are trying to start "right now". Droid Explorer uses 1.6r3 with the current install, the next release has 1.6r4.

Out of curiosity, what is the app doing that "requires" busybox. With Droid Explorer, I use busybox's ls command because the stock one sucks and doesn't display all the information when doing a ls -lF, plus i dont think it supports --color=always

Woah! you actually did a fresh install of windows to get this app working?
anyhow, if you open a command prompt and type "adb devices" what does it output.
Make sure you have USB Debugging enabled on the device. Settings -> Applications -> Development -> USB Debugging
Thanks camalot for your help, you are good guy. And also THX to you UpGrad3 (you are first ).
BTW new version soon
hmmm doesn't seem to work well with a multi-monitor setup or maybe some other issue.
When I start it with the phone not plugged in I get the Device not found off to the edge of the monitor. (APK Manager shows on the taskbar)
Connect the phone and Refresh and it's found and click OK.
Then your app disappears... nothing the the taskbar but if I check Task Manager it's running.
Little help please
Oh yeah WinXP SP3

m8 before u run this program in recovery mode u should type in windows cmd "mount -o rw /dev/block/mmcblk0p2 /system/sd" and "mount -o rw /dev/block/mmcblk0p2 /sdcard" then its works ok
I have done a clean install of cyanogen 4.2.9.1 cause i had too much stuff on my fone so i thought id clean it up a little bit and since that android commander is not working again so its something to do with my phone does anyone kno what may be wrong ? thanks.
new version available
this program is so strange for me if i do a clean install of cyanogen it doesnt work well version 0.5 didnt and after a day or two when i have lots of apps installed to the phone it works i dont understand and now the latest version 0.6 doesnt work but it works in the places 0.5 didnt e.g. it allways opens up no matter what even on clean install so this has been improved only now it doesnt detect my phone when connected i have attached screenshots to help me explain they are here:
when i open the program i receive this message:
and when i click ok it opens like this:
please fix this cause i really like this program and appreciate ur work
as i said before, it's not program problem. this error showing because of program can not read informations form your phone. many people had issues like you (also on different forums), and every time problem was with SDK/ADB.

[PROGRAM] Updated:One Click Root/UnRoot (Mac and PC)

Team,
This One-Click Root process will copy over the rooted-update.zip or unroot-update.zip file then reboot your phone. Follow the instructions in the CMD prompt that launches.​
Credits:
LeshaK at Samdroid: for the original rooted-update.zip.
gunnarhafdal : for creating the Mac GUI for my app.​
This has been tested on stock Android 2.1 Eclair only. If you rooted using another process you can use this process to unroot as long as you didnt load a rom that created links to busybox.
For the following models:
GT-I9000
Captivate SHG-I897
Vibrant SGH-959
GT-I9000M
Epic SPH-D700 (Untested but should work like other phones. Post with your results. This is harmless it will either work or it wont. It copies over 3 files to your existing build.)​
Rooting adds the following to your system and unrooting removes them:
/system/xbin/busybox (version 1.17.1)
/system/xbin/su
/system/app/Superuser.apk (version 2.3.1)
and links /system/bin/su to /system/xbin/su​
More will follow as they are released. PM me to add your Galaxy S Model.
Warning: I am not responsible for bricked phones, rooting can void your warranty....

Download the app: GalaxyS_One-Click_Root_All_Models-PC. Or down Below.
Watch the video for the full procedure on The Unlockr.
Video/Procedure Link Click Here
Requirements: Install Link: Dot Net Framework version 4
Rooting Instructions:
1. Make sure your phone is on USB Debug mode: (MENU > Settings > Applications > Developement > USB debugging = Checked )
2. For Windows x86 and x64 systems make sure that the Samsung Drivers are installed. You can get them here.
3. Extract the contents of GalaxyS_Vibrant_One-Click_Root.rar to a folder.
4. Connect your phone to your PC via the USB cable and launch the file "T-Mobile Vibrant One-Click Root.exe" file.
5. Click the "One-Click Root" button. This will launch a command shell follow the instructions in the CMD window.​
Mac Instructions:
Download the app: OneClickRootMac. Or Down Below.
It requires Mac OS X 10.5 or higher.
Rooting Instructions:
1. Make sure your phone is on USB Debug mode: (MENU > Settings > Applications > Developement > USB debugging = Checked )
2. Connect the phone to your computer.
3. Click one of the buttons depending on what you want to do.
4. After the phone has rebooted into recovery select "apply sdcard:update.zip" for I9000 and I9000M and choose "Reinstall Packages" for the US models using the volume keys and then press the home button for I9000 and I9000M and the power button on the right top side for US models to start the process.​
=====================================================================
Done! You are rooted.
=====================================================================
Un-Rooting Instructions:
To Un-Root follow the same instructions except click on the Un-root button. If you rooted using another process you can use this process to un-root as long as you didnt load a rom that created links to busybox. I would suggest to restore you phone back to stock ROM before even needing to unroot and if you are on stock un-root all you want otherwise what is the point of un-rooting.
=====================================================================
Getting Started with Android After Rooting:
Flash Clockwork Custom Recovery On your phone:
Follow this URL to find fill information on ROM Manager:
http://forum.xda-developers.com/showthread.php?t=734164
Install ROM Manager from Market.
Launch ROM Manager and click on Backup ROM and save you android O/S stock rooted making getting back to stock un-rooted much easier..
the simplest root just got simpler
So is this actually faster? Or just "easier" not to mess up...
sounds like more work than just DLing, moving, and renaming with your phone... expecially for those without a comp...
anyway, this method has been added to the sticky in dev section..

I'd say its easier to not mess up. Faster for sure, if you already have the drivers installed.
This is for our newer brethren or anyone else that want a straight forward root method. And for those having trouble entering recovery from the button presses. ADB is bundled in the rar file so you don't need Android SDK.
Another thing that will help most is when I add unroot to the app which I should have completed tomorrow.
Doon2 asked for it, so here it is.
I appreciate the effort and skill...
BUT, how is this easier than downloading a file directly to your phone, renaming it and putting it at the root of your sd card and going to recovery?

Good question because that is what I do. Just an alternative method. The upcoming unroot will probably be more helpful to some.
But this method will help some for sure. It will download it to your phone for ya and put you in recovery. Well most of the other phones have it so why not ours.
Someone made the request and here it is. I will also be adding other tweaks to the app over time and useful info after rooting to this thread.

I am stoked that someone would take the time to make this program. I dont have immediate access to a PC(I use a mac) but an easy unroot program clinches the decision to root my phone. thank you for taking the time to make this much props
please do it for Mac OS.

I know what you mean. I'm still used to holding down the buttons until the recovery screen pops up like on my G1. On the Vibrant, I have to remind myself to let go of the buttons as soon as the "Vibrant" screen comes up.
Yes, the overall process involved to use this program is longer, involves more steps, and, therefore, easier to screw up. Also, the fact that you have to download more than one file increases the chances of messing something up because of the possibility of corrupted files. Also, the "flash in recovery" method is OS agnostic, and technically doesn't even require a computer since you can download and rename the zip file right on your phone if you want to. Still, it's very easy to follow and would appeal to those who are new to rooting and don't feel comfortable with booting into recovery mode.
Updated the app to include unroot. Created a new update.zip file that will remove root. Also fixed the CMD shell launching minimized.
Lets see the java port. or even an APK to do so

Why fuss with button pushes, just enable debugging, plug in your phone, open a command prompt and type the following
Code:
adb reboot recovery
It's easier than messing with those buttons I assure you.

[GUIDE] [NEW] Root All L90 Varients with Latest updates [EASY]

All Credit to @thecubed. Please thanks him on his OP here
This is not my original work.I am just sharing this GUIDE for easy rooting of L90 with latest updated, those are not supported by towelroot.
I have tested this method myself and it is working perfectly for me, but it is also possible that it might not work for you for some reasons, so don't panic, just post your problem or whatever error you are facing (please attach screenshot if possible). I or other thread members will try to troubleshoot it. After resolving the problem I'll update this post, so that other members do not face such problem again

PLEASE, USE THIS TUTORIAL AT YOUR OWN RISK, IF SOMETHING WENT WRONG (because of your stupidity) ME OR XDA WILL NOT RESPONSIBLE FOR YOUR LOSS.
I HAVE ONLY TESTED THIS METHOD WITH MY L90 D410 AND IT MUST WORK WITH OTHER VARIENTS:fingers-crossed: . BUT STILL FOLLWO THIS GUIDE AT YOUR OWN RISK
Click to expand...

First of all Install USB Drivers from following link :-
Click here to download L90 USB Drivers
After installing USB Drivers, download Rootl90.zip file attached to this post below and extract it to C Drive of your PC.
On your phone, Goto Settings -> General -> Developer options and enable USB debugging by ticking the check box.
(If you are unable to find Developer options, then go to About phone -> Common -> Software Information and continuously tap on Build amount for 5 to 6 times, it will enable developer options)
Now Connect your phone with PC in LG Software mode, open device manager and confirm ADB Device listed at the top of the list, as an image attached below:-
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Now open Rootl90 folder, that you extracted to the C drive in the first step.
In this folder, press and hold shift key on the keyboard, right click on blank place and click on open command window here. The command prompt will start with c:\Rootl90>

Guys plz reply if worked for other than D410 Model
D410 here, after first command wait til the drivers are installed,
There is a redaction error in your comands, the correct are:

I've tried it on D405n and it works. Thank you.

LOOOL
Why should i use
Code:
adb reboot --bnr_recovery
adb push start_restore /temp/start_restore
adb push permaroot.bin /temp/start_restore
adb reboot
when i could use simple original purpledrake way. i think you took the files from purpledrake thats all ? or i am wrong ???
Does not work on t-mobile LG L90, D415 with the software version D41510e.
adb reboot --bnr_recovery reboots to a blank screen. Presumably it's still a recovery -- adb connects. But "adb push start_recovery /temp/start_recovery" does not work -- no such file or directory. Changing the destination to /tmp in both adb push commands does push files to the phone but there is no root after reboot.
Looking at the purpledrake script, I also see that the vulnerability tests looks for a process "brd" on the phone but there is no such command in the output of ps.
Any ideas?
LG L90, T-mobile D415 with SW version D41510c also does not work.... same exact issue as described above...

You should use TowelRoot app, it roots the phone in like 2 seconds and no reboot is required...
Search in google for "how to root T-mobile LG D415" - first link has few instructions but leads you to the website where to download the tr.apk (if doing from phone) long click on lambda sign and select "save link" ... thank install the app and run it... 2 seconds... done...

Towelroot works on the previous SW version (was it D41510c? I don't remember). But there is an update to the version 10e and towelroot does not work on it (at least it did not work yesterday, this was the first thing I tried). Unfortunately, I updated without checking forums and I might have forgotten to turn on survival mode in supersu (although i'm not sure survival mode works).

Towelroot worked fine on my D41510c. I have not updated though, and probably won't as some say nothing really changed with the update.
I have that version and I was able to root with towelroot - it did not even request a reboot or anything... just 2 seconds of my time...
I am now running CM11 and it flies - this phone has just stepped over few models that are considered to be "faster":... not in the CM world

Which version do you have 10c or 10e? Is this T-Mobile phone? If it is 10e -- did you just use towelroot straigtforwardly? Was the phone rooted prior to 10e upgrade?
I upgraded rooted phone from 10c to 10e, possibly having forgotten to turn on survival mode in supersu, and lost root. I still have adaway's host file (so ads are blocked, now permanently since I can't go back to the standard host file), I still have supersu files in relevant directories but no root when the phone is running. And towel root says that it can't work on my phone. I was just assuming that the update has a newer kernel that fixes vulnerability exploited by towelroot. I'd love to recover root if I could.

Hello!
I would have just a short question about the root. If I make the root with this towelroot am I loosing the guarantee? I mean this procedure is open the bootloader or this is just a "smooth" root?
Thank you!!!!

Thank you for your quick reply.
So if it is just a simple root and in the future I will have some problem with my phone I will be able to put back the original software to the phone without any mark? Because at Samsung phones have a special trick. If you root your phone and the bootloader is open the Knox code (this is the special trick) is jump from 0 to 1 and you will not be able to replace it anymore and you will lose the guarantee forever with it.
I wouldn't like to change the software on my phone I just would like to install programs to the SD card but it is not allowed under the KitKat unless I root my phone. But I think the simple root should be enough for that isn't it?
BTW. Will I need a special program after the root is I want to install to SD card?
Thank you very much!!!!
Before I do this I would like to know if there will be a custom recovery like two? Does this work with the D415? Would I still have my T-mobile connection? I only rooted my Nexus 7 2012 with the Nexus root Toolkit.

Device not detected in Fastbootmode.

SOLVED:
The reason Device was not detected in Fastbootmode was due to my new ryzen 3000 system, I tried it on my much older quad core 46XXk(?) Intel system and it gave me no problems whatsoever finding the device in fastboot mode in my first try! wtf amd!
The second Set of problems came with flashing 16.0631.1910.64. It gave me a ton of errors and it was on an infinite boot loop, nothing I tried fixed it, my device was a worthless brick in that state, but fastboot Power+Volume up > 16.0631.1910.64 worked perfectly.
I decided to instead try 16.0631.1910.35, but once I flashed it everything worked perfectly! I am in the latest version of android 10 atm and can acess banks, play nintendo games, etc with the rooted device.
Hi, I bought this phone (Rog 2) mostly Intended as a donation for a friend that was complaining on facebook that he's probably going to be homeless due to covid and didnt even have his phone since he cracked the screen. While I cant help with housing I can help with a measly phone and I heard for gaming this is one of the best.
I got the tencent version not knowing what the heck I was getting myself into ( I thought all ROG 2 were the same and didn't even think to look it up). Been googling for days, I am trying to make this a full WW variant and basically as hassle free as possible for him, it seems that it has an obscure version of "pkq1.190414.001.ww_phone-16.0622.1906.19-0 " Rom, but according to HWInfo the fingerprint is CN.
Problem is I tried following this guide, I unlocked the bootloader with the ROG phone unlock tool, but on step 2 I load into fastboot, click flashall_AFT but all I see is a cmd with the message [command] : fastboot.exe flash all WW_ZS660KL_16.0631.1910.35_M3.13.33.30-ASUS_1.1.207_Phone-user.raw and nothing happens.
I noticed that on the cmd of the minimal adb devices and fastboot folder, the "adb devices" gives my device , the "adb reboot bootloader" works by taking me to the bootloader, but the "fastboot devices" does not give me anything at all once im in bootloader. In fact when using adb reboot bootloader I hear the windows beep as if the cellphone is disconecting. Any ideas what is going on?

Have you installed adb drivers https://github.com/koush/UniversalAdbDriver
Also, just checking the obvious, you are using the side port of the phone, not the bottom, right?

Hi! Yeah, I have the exact same driver you mentioned as well as Minimal ADB and Fastboot and using the black sideport.
It seems when I connect it during the fastboot(Green arrow menu) I do hear the "USB Device plugged" sound so there's that.
flashall_AFT still just gives me a black page with: [command] : fastboot.exe flash all WW_ZS660KL_16.0631.1910.35_M3.13.33.30-ASUS_1.1.207_Phone-user.raw

Before running flashall_AFT.cmd, when you hear the device connect, have you tried entering 'fastboot devices' before doing anything else? See if it gives you a serial. If it does.
Then have you removed the original zip file from the extracted folder that contains the raw img? Once you click flashall_AFT.cmd, the cmd window should stay open for around 5 minutes while the flash takes place, then the phone will reboot once done

Top left image is from using the "fastboot devices" command, as you can see I type it it doesn't show or seem to do anything really. The right image is from clicking flashall_AFT, both inside bootloader on my rog 2 and outside give the same result.
The Zip file? As in the 2.7 one I downloaded? Yeah that content of that is in a folder in root of C drive, the zip is in a completely different drive so they are not sharing a directory . I did not modify anything inside the extracted file though.

Ok, try unpacking the attached zip to root of C, like the other adb folder. Then click on 'cmd-here.exe' to launch cmd window and then try 'fastboot devices'. (that's assuming the drivers of the original install are working). Let me know if you get a serial response.

try this version, after installing the drivers you could also try that folder with the cmd-here file in combination. Also, try booting into android os and enable developer options (click on 'build' 7 or so times in settings/system/about phone/software information/build number), then go to developer options and enable USB debugging - might make a difference...
Also, check your pm, I sent you modified instructions for using the other guide that'll take you straight to last Android 9 version before you can update to Android 10 (1910.64). You could always be downloading that newer RAW + root img while tinkering with getting the damn thing recognised by your pc!!
Tried the 1910.64 you sent me and its the same problem unfortunately, still stuck on step 2. I already had USB debugging with the "USB debugging" option ticked on when I created the topic.
I take it doing number 4 Is a bad idea if can't get past 2? "4) Download the root&bootstockww191035.zip "rootww191064" and extract it to the Minimal ADB and Fastboot Folder (C:\Program Files (x86)\Minimal ADB and Fastboot) from here "

Yeah, there's no point continuing until you can get fastboot devices to at least show your device. Do you have another pc/laptop you could try on? Are you using an AMD based system, pretty sure I read somewhere that can give issues, along with the system used! Sorry that's a bit vague...

Oh sorry, you meant try flashing the root img, NO, definitely not. The root img MUST only flashed after successful flashing of RAW - both rom and boot/root boot img's must match. (But either way, if your device isn't recognised by fastboot it just won't flash, just an FYI)
See this thread for info on Ryzen issues, if that is what you're running. The OP says he used an external USB hub as a solution

Do you have above 50% charge? If not, definitely make sure to have enough charge for the whole process. I was always of the understanding, as a rule of thumb, to have devices above 50% before performing flashing of custom roms etc

Yeah the charge is over 90 percent, anything I can do for that error? when I connect to the intel pc it doesn't even beep any more. I still can access the boot screen though.
EDIT: OOPS, noticed I had it plugged on the bottom, nvm intel system still detects the device. I did perform everything on the side port usb but I took it out to try and check back on the ryzen system.

Question My computer doesn't recognize the phone in fastboot even with drivers installed

Hi all,
I really need your help, my computer doesn't recognize the phone in fastboot, I've installed different drivers and none of them work, in device manager it appears as Android with the yellow exclamation mark. I've already enabled USB Debugging mode, not sure what am I missing, please help.
Check in another USB Port, use original xiaomi's wire...and install latest USB drivers
I have the same problem, i'm using the original xiaomi wire and already installed lastest usb drivers.. the fact is that when I plug in the cell phone in fastboot mode the computer keeps sounds as connecting and disconnecting the device (I used two wires and two different computers)
Yup exact same thing, I hope somebody knows how to fix it and help us out.

Hi, where do I get the USB drivers? Even the official website says to make sure that "your PC has necessary drivers", but they don't provide any link where you can get them.
The Unlock Tool only has a "Check" button next to the version number, which says "5.5.224.24(Already latest)" and again, no drivers check. There are tons of fishy websites that claim to have the drivers and I have already tried several of them, but no success. Your help would be much appreciated.

Hi, after almost 2 days of constant researching and trying and failing and testing, I have finally figured it out! You need two things: MediaTek Driver and disabling Driver Signature Enforcement in Windows 10. It's because normally, the (64-bit) Windows 10 system won't allow you to install an unsigned driver and the Mediatek Driver is unsigned.
Here are the steps:
1. Press the Windows key on your keyboard, open PC settings
2. Go to Update & Security
3. Go to Recovery tab
4. Press & hold Shift key on your keyboard and click the Restart now button (in the Advanced startup section)
5. Select Troubleshoot ->Advanced setup -> Startup Settings and press Restart
6. Press 7 number key corresponding to "Disable driver signature enforcement" entry.
The system will now boot with the Driver Signature Enforcement disabled (it's going to be automatically enabled with the next restart). Download the Mediatek Driver (official source), unzip the file. Here's how I installed the driver:
1. Press the Windows key, type Device Manager and open the utility program
2. Click the top item in the list (your PC's name) and click Action in the menu and select Add Legacy Hardware.
3. Click Next in the Wizard, select Install hardware manually, and again Next and Next again.
4. Click Have Disk, Browse, navigate to the unzipped folder: SmartPhoneDriver > x64 > Unsigned infs and select the file android_winusb.inf. Click OK and select Media Tek Inc. in the left pane and then Next and Finish.
Your phone will now finally appear in the Unlock Tool.
This should work for all Note 10s users who also happen to have a 64-bit Windows 10 machine. Let me know how it went for you.
hey Guys, i´m new in the forum. But i had the same problem and i´m bringing the solution.
This error happens because Windows doesn´t recognize the bootloader, then you must install manually the bootloader´s driver and connect again your phone, so simple. I´m attaching the driver in this post.
Cheers.
