Hello friends,
How to get into fastboot to relock the bootloader, if my volume button is dead? By dead, I mean the ribbon has been ripped off of the mobo (it was soldered onto mobo).
Since I'm a brand-new noob, the only way I know of and have done is to get into fastboot mode and lock it back up like what I did when I unlocked it. Any other way to lock it, ideally within the Android OS? Since my volume buttons are completely dead, I doubt that I can get into any "mode" other than OS right now..
TIA!
adb reboot bootloader.
I've seen that command in a post from search earlier, but there was no response after that post.
Would you explain the procedure? I am afraid that I might do anything wrong on top of these disasters i've gone thru with this phone
I also saw another line during earlier search: "if they don't know how to setup an adb command, they probably shouldn't unlock their phones"... Looks like I've done what I shouldn't..?
I would say doing whatever ripped the volume button cable out was what you shouldn't have been doing If you unlocked the phone you have the software you used to unlock, right? What software/guide did you use/follow? Are you using Windows/Linux/Mac? The only way to get to the bootloader w/o the volume buttons (afaik) is to use adb via usb. If you provide more details I can try to help you.

Once you're in adb reboot bootloader, do fastboot oem lock. Opposite of how you unlocked it in the first place

navigate your cmd line to the folder with adb and fastboot in it. Hook the phone up to the computer and type:
Code:
adb reboot bootloader
which will make your phone reboot into the bootloader mode. You can then proceed with what you need to do.

I agree with whoever said that. This is another example of people messing with things before reading and learning how they work.
Thanks for your help guys!
btw, anyone found xdadevelopers to load extremely slower in Firefox when compared to Chrome? (just offtopic)
Anyway, I unlocked the bootloader when I was switching to yakju cmd and this folder called "fastboot-and-adb" in which there is both adb.exe and fastboot.exe. I used command "fastboot unlock bootloader" or something alike.
I'll do some more search and learn. Don't want you guys to think of me as a lazy bone who unlocked their bootloader using 1-click toolkit
p.s. edit: in my other thread, someone suggested using quickboot app.
Thanks for your replies guys!

Somehow it says device not found
I do have proper driver (Naked Driver Beta 0.5 by 1wayjonny) that my phone was able to be recognized under bootloader at the time when I could actually get into bootloader. My phone is also being recognized as media device now... I have also turning usb debug on...
Try adb remount
The ad devices
This should list the serial number
Then all commands should work

You need to turn USB debugging on, and then type "adb devices" and see if it shows up. It may not using the Naked Driver; I had to install the full Samsung USB driver package before ADB would see my Galaxy Nexus.
If it does show up, then you type "adb reboot-bootloader" and it should boot into fastboot. Then just type "fastboot oem lock" and it will wipe the storage partitions and restore the bootloader lock.
Thanks for the help at late night guys. I finally got into the bootloader, thru a mac tho Kinda ironic that I am a supporter of Windows, well, at least a firm user of Windows.
Tried adb remount, it still says device not found

I believe that you quoted my "I have turned USB debug on" ;p
Gave up on trying Windows drivers. When I was flashing the Yakju, I tried Samsung full driver, and it didn't work on my machine, i.e., the phone can't be detected in bootloader mode, while the beta 0.5 driver worked. So I decided not to mess with it anymore.
It looks like when the phone is not under bootloader, windows recognize it fine as MTP devices and install proper samsung driver from the internet directly. This allows me to open it up in explorer to browse files and such, but the phone won't show up under adb devices somehow.
Looks like MTP device (when the phone is in Android OS) and the fastboot mode use two kinds of drivers. This is just my assumption, though.
Anyway, finally got into bootloader now with Mac, and it's pretty funny I have to do everything thru command as the volume rockers are dead
And most importantly, thank you guys for your help!
Just another update
It's real funny now that the bootloader is locked, I can't unlock it again cuz I don't have the volume button working, so I couldn't choose YES on the phone.
I'm not trying to unlock it again, but just to confirm if there's really no work around, in case I encounter this situation again in the future
Lucky that locking the bootloader won't erase everything, or I won't be able to flash a ROM with it locked... :cold sweating:

Been so busy in the past few months or so that I couldn't do my helpful stuff. Now I have more free time.
Awesome tutorials! this is where I'm stuck at the moment.
I went as far as to restore my computer to Windows 7 and start over erasing everything. I've tried different USB cables. I know it won't work on my USB 3, i Have one USB 2, I believe I have the drivers installed. I even went as far as to download and install Cyanogenmod on my Verizon HTC One. Enable root, Apps and ADB. allow USB Debugging. I also uninstalled HTC Sync, because another XDA guy mentioned that it can get in the way of things. here is where i am stuck at when attempting to lock my Boot loader.
C:\Program Files (x86)\Minimal ADB and Fastboot>adb devices
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
List of devices attached
C:\Program Files (x86)\Minimal ADB and Fastboot>adb shell
error: device not found
So that is where I am stuck. I see my phone reads fastboot usb, and it will do other commands, so i know it is connected, just not recognizing it? Dumb question, but if I RUU to say 4.2.2, because my phone is able to do that, can I do a software update and install 4.4.2, would that LOCK my bootloader and get me on the right software, so that all i have to do is give the command to go from S-Off to S-On? or will that command even work for me because i cant get the command to even open the shell? Also, is there a way to manually install a driver? I go to my device manager in control panel, and I'm not seeing anything that says Other Devices > One.(UPDATE; I found where HTC is in device manager, I tried updating the driver manually, it say's that driver is already up to date.) and I've gone to the start menu > Run > and ran a command to allow me to install unknown drivers to Windows 7. I have also unplugged anything usb on my laptop, including my wireless mouse.
I've been trying really hard to get my phone back to stock to return back to HTC. Probably a solid 10 to 12 hours last night and this morning working on it. lol
Update: Am I supposed to do anything with Android SDK?
Update 2: I can flash Decripted RUU running adb on CMD with commands and have HTC's Official software running with no problem and it recognizes my phone plugged in. So i went back to Cyanogenmod for now. but for whatever reason, adb device and adb shell are not recognizing my phone that is plugged in
Update 3. Re-installed HTC Sync and installed HTC Sync Manager for the fun of it, and now daemon doesn't even show up when doing command adb devices
C:\Program Files (x86)\Minimal ADB and Fastboot>adb devices
List of devices attached
Update 4: I swear, when we get this working, I'm gonna send whoever a little kickback through Pay pal for helping out with my issues.lol. I feel that maybe it could be my laptop, I'll have to try my 10 year old toshiba.

Uninstall the phone in device manager. Disconnect the phone. Disable windows updates to prevent it from auto installing a generic windows driver. Then plug the phone back in and try to manually install the driver from the video.
Okay. I'll try that out here in a little bit. Another thing I found to be odd, is that my OS is showing up as blank. I hope it will show the correct OS that I'm on, when I get far enough to flash an RUU.
Success! I had to disable updates, even after that, it still would update when plugged in. So I uninstalled updates. Then, I had to catch the device drivers before updating by cancelling them. Installed drivers like in the video, followed steps, everything is a success! this post should be stickied, but that's just me. Good job!

Glad you got it working.
Windows update is nice, but it is really annoying when you want to manually install a better driver.
Great tutorials. Much appreciated.
Can you verify this is working for version 4.4.2? I gave up on my One a while back after running into 8.1 driver issues. Apparently that has been resolved now as well.

I rooted and got S-Off on Win 8.1. I was stock 4.4.2 at the time and never rooted a smartphone before. The tutorial for the driver was spot on. As for the other 2 tutorials, I didn't use them as I found the rest of the process to be pretty straight forward (using WeakSauce & Firewater to root and get S-OFF).
Vids now viewable in OP.

Excellent to hear. Been waiting for this to get sorted out. Will report back when I get time to sit down and run through it all.
I can confirm it works on win 8, got my surface pro adb and fastbooting like a baws in minutes. As above poster mentioned, you either have to uninstall and prevent auto device installation, or if you find it in device manager you can force update the driver , you may have to take the extra step to "Have Disk", manually select the androidusb.inf file from unpacked drivers, then select My HTC

What version of Windows?
If it is Windows 8 you need to make sure that you installed the drivers while signature enforcement was off. I have also posted an updated video with new drivers, give it a try.
I have had this watch for about an hour now... ANNNND the bootloader is unlocked...
easy steps below
Note For Clarification: you CANNOT do this over Bluetooth.
Enable ADB and connect to computer.
reboot into fastboot using: adb reboot-bootloader
then issue command: Fastboot Oem Unlock
accept the prompt on the watch.
then reboot the watch...
Piece of cake.
Now... about that boot logo...
Yeah its like a nexus in that regard. And no I don't have the watch yet but have ordered it today.
I would unlock mine but there's no reason to yet. I always unlock my Nexus devices first thing yet with the watch I would like to keep it stock for now.
No reason to unlock, until someone creates twrp, and root.

I agree, a factory reset on it only takes 2-3 minutes so its not like a phone where it takes forever to set up again.

Have not done it, but fastboot takes the -s parameter as well. So I would try:
fastboot -s localhost:4444 oem unlock

Cannont get USB drivers to work
I tried bith google USB drivers and ClockWorkMod universal ADB drivers and cannot get my Huawei to properly connect. I tried two separate computers with the same result. Each time the USB drivers seem to install but the watch shows up under other with exclamation point. My objective is to side load watch face apks to see what I can accomplish with running this watch under iOS.
ADB debugging is on and I also tried also turning on Bluetooth debugging. Intersetingly Bluetooth debugging does kick in.
I'm a novice at BT debugging and any attempt to communicate with the watch following on-line guidance did not work.
Any suggestions/help would be appreciated.

What does "issue command: fastboot oem unlock" mean exactly? There is a little red action name which I can cycle between "Reboot", "Shutdown", "Reboot-bootloader" and "Reboot-recovery", none of which seem remotely correct. I went into "Reboot-recovery" to see whether there was further stuff in there, but nothing seems relevant.

So what this means is you need to have ADB and fastboot setup on your computer. From there, you will need to go into developer settings on the watch and enable ADB debugging. Then once you have that enabled, go to where you set up ADB on your computer and type in those commands provided.
P.S. If you're sitting there not sure what ADB means and how to set it up, you NEED to do more research before trying anything like this.

Actually, it has been a bit of a ride.
I knew of adb already from my watch face development so I had initially wondered whether fastboot was a subcommand of that. I didn't expect it to be another command in the SDK at all for some reason. But yep, it's in the same place as adb, and it works, and now everything flashed fine. I don't know why I didn't search my computer for a file with that name, since that would have located it.
Un-hiding the development options is mentioned on the wear developer site so that was fairly easy to set up. The only hard part was that they gave a text-only explanation, but this watch came set to Chinese, so it was a bit fun to figure out which button to press to "confirm" a dialog. I recognised the first option as the "no" and the second option turns out to have been the "yes", but there are more options below that I still don't know what they are, lol.

You are quoting me from 4 mos ago? LMFAO!
Hey fellow members,
Since a few days my ADB is not working with my phone. Every time I try to connect it as an ADB device I get an error (See attachment) that my device is unauthorized.
I've read a dozen threads about this problem and I think it is the RSA Fingerprint. I don't get that pop-up anymore, when connecting my device to authorize the PC.
Here's what I've tried already
1.
Code:
adb kill-server
Code:
adb start-server
2. disable and enable USB-Debugging-Mode
3. Copy the adb key from C://user/me/.android. to the phone's directory /data/misc/adb
4. reinstall drivers on PC
5. Reboot PC and Phone
None of that worked. None. I'm desperate. Been looking for 6 hours yesterday and couldn't fix it.
If anybody has had these kinda problems I would be totally grateful for an answer.
I have the intl version of H815, bootloader unlocked, TWRP and SuperUser working fine. I'm currently on V20C (6.0 Marshmallow)
Any help would be extremely nice.
Best regards
Hi,
Did you solves this as I am having the same problem after doing a factory reset?

Unfortunately no. I've really tried everything. I even flashed a complete new kdz (at least upgraded to one), to no avail.
And this thread doesn't get enough recognition or any advice from a pro, so I'm heading dead ends.
I'll let you know, when I found a possible solution and post it in this thread.

Hi,not a solution as such but I wanted adb to get into the bootloader. Instead I installed a terminal emu and got into it that way. Not sure what you are trying to achieve but this may be of some help.
Same problem for me... Device unauthorized, no rsa prompt... Tried it factory fresh, no success.

I want to access my device via ADB, e.g. pushing files to my phone, installing, wiping, etc.
Which I can't, since my computer, or my device is unauthorized to do so.
I just can't enter ADB commands, which is pretty annoying, since I often use it to push files to my phone or print out a logcat.
Well nothing's working so I gotta be patient until anybody comes up with a solution :good:
The strange thing is, i do also own an oneplus 2. It doesn't get authorized too, but is asking for fingerprint. Do you have win10, like me?

Yes I have win 10. You're one step further than me. I don't even get an RSA prompt. Don't know why yet

Refer the below thread, hope this helps

EXPERT FROM THE ABOVE LINK:-
I was not getting the RSA fingerprint pop up on my phone.
I had to go into the C:\Users\.android\adbkey and adbkey.pub
files, delete those and then do kill and restart of adb server. I had to stop and restart the debugger and connecting as USB in PTP mode.
Because the RSA authorisation key was getting stored in this path, killing and restarting the adb server didn't help.
Just wanted to reiterate the person above me as it helped me with my problem. So in case anyone out there on the internets runs into the same issues try these instructions.
1. boot your phone into recovery
2. now try doing adb devices in your command prompt - it should show up as LGH815xxxxxx recovery
3. type adb shell
4. type cd /data/misc/adb
5. type rm adb_keys -- this will delete any existing adb key from your device **
6. type exit to leave the shell and then reboot your device as normal
7. in windows find C:\Users\<your username>\.android
8. delete the existing adbkey.pub file
now you can proceed as normal with running adb devices, and you phone will prompt you to confirm.
** note you can also delete the adb key from android from within your android OS. go to settings > developer options > revoke USB debugging authorizations. i guess you can do it from recovery just to make sure.
Hello guys,
I am an unlocked LG G4 user running on Android 5.1 Lollipop.
I cant recieve updates through OTA as it always says "You have latest version of current OS". So I tried updating manually.
Since I am not very good with LG flash tools I was looking at unlocking bootloader and twrp.
The problem is :
My hardware info shows "LG H815"
Adb recognizes it as "LGF500L204da3d4 unauthorized"
A google search told me that F500L is Korean variant and now I am totally confused. Am I missing something here.
I have attached screenshots of device info.
Please guide.
The unauthorized thing comes from enabling ADB in the Developer Options. Once you do that, the very next time you connect the G4 to a computer and then run the "adb devices" command it starts the adb daemon and then tries to connect to the device, upon a connection the phone not the computer will pop up a box asking for permission to allow the connection based on an RSA fingerprint (aka the security aspect) and you have to allow that.
Without allowing that you'll never get ADB to work properly. You can try this process to get things working properly:
- Disconnect the G4 from the computer entirely
- Disconnect it from any charger too just so you're good to go
- Go into the Developer Options, revoke all using the "Revoke USB debugging permissions" and reboot the G4 right then and right there as soon as those permissions are revoked, do NOT do anything else, reboot immediately after you make that change
- Upon the reboot let the G4 boot completely and wait 2 minutes before swiping/unlocking the device back to the Home screen
- Plug in the USB cable and make sure you choose the MTP/file option, not charging
- Fire up the adb devices command on the computer and watch the phone carefully for that popup asking for permission to connect
- Choose OK to enable the connection and check the box to make it permanent for that specific computer
After that it should show you the device serial number and say "authorized." If not then you're missing something or there's some other problem, but that's how I've done this on a few hundred devices over the years and never had an issue. The other thing that could be affecting this are making sure you have the proper ADB drivers, sometimes that can be a complete pooch-screw to get working and I can't help on that front.
Pic below is what you're looking for and without granting this permission ADB will never see the device as authorized.
Good luck...

Ok..So I tried as per above instructions.
The only change is it's written as "device" in place of "unauthorized". The serial number is the same.
I thought it would be written as LGH815...etc etc for the H815 model. But here it's F500L...
Is this normal?

Update:
Found something interesting as well.
The phone doesn't boot into recovery using hardware keys.
I tried with adb and got into a screen showing "No command" with red exclamation.
It means you don't have a working recovery partition now so something got borked. Best case scenario: do a full factory reinstall of the stock ROM and go from there, maybe, using Odin or whatever tool you prefer, these days I have no idea what software there is to be honest.
I don't own a G4 anymore either, but if I find one in good shape for a good price, like $50 or less, I'll more than likely grab it.

Maybe I should just keep it as it is coz I don't even know what rom to use and actually which model it is.

Used to believe HTC devices are tough nuts to crack but LG just blowed me away.
