Hey there. I'm new here, and to be honest, I'm new to the world of smart phones. The 4xHD is my first smartphone and I've had it for about a year now. I've noticed that it performs really badly on the 4.1.2 JB so I've decided to root it, unlock the bootloader, flash cwm and get a Cyanogenmod 10.1.3 up and running on it.
Long story short, I've rooted my phone and followed this http://forum.xda-developers.com/showthread.php?t=2245836 thread to unlock the bootloader but it didn't really go as planned. I did the things in the cmd app on the phone, and did the first line of cmd on my lap top (adb reboot bootloader) and when I wanted to do the second line (fastboot oem unlock) the cmd said it was waiting for the device. I waited for 5 minutes and nothing was happening on the device. It was stuck on the LG screen (not the one with flashing lights, just the logo screen). I pulled out the USB and pressed volume down and the power button just in case. Then I pulled out the battery, turned on my phone and went to the 3845#*880# secret menu to check the bootloader status. When I tapped on the bootloader unlock check thing, it said "Unlock".
So, did I just unlock the bootloader? Operation successful? Is there a possibility that I didn't unlock the bootloader in a correct way so it will brick my device when I try to flash cwm and Cyanogen?
I'm really sorry if this thread is in a wrong section or something. I searched on the xda but couldn't find the answer to my question.
Thanks in advance
EDIT: I'd also like to mention that in no part have I encountered the screen which said "you're about to unlock your bootloader, warranty voiding, blah blah blah, are you sure you want to proceed"

Hello:
I sent my NEXUS in to SAMSUNG for a touch screen non-responsive on the left side issue. The tech stated there were no problems with my NEXUS S!
Upon turning it on, there is a padlock on the botton of the Google splash screen.
I called Samsung and the "level 3" tech said that my phone was now locked to T-mobile. I though that was BS.
Anyway what is it and, can I get it back to normal? My wife has the same phone and here does not have any problems so far.
I've attached a pic of the screen that shows the padlock. Thanks for the help.

that means your phone is unlocked as far as I know. I did my first unlocking and rooting of my nexus last night. When I went through the unlocking process, the "unlocked padlock" started to appear on my startup. If you hold "volume up" and the power button and turn the phone on. it should say unlocked on the fastboot screen...
You have unlocked the bootloader my young Jedi.

yup, unlocked bootloader.
thats not a bad thing, its a wonderful thing!
lol you rooted your phone and unlocked the bootloader. that is what that lock symbol means. did you forget, or not do this on purpose?
Thanks to all that replied!! I kinda figured that is what it was.. Like I said I didn't do it, the Samsung repair facility in Texas unlocked it. I called the Nexus S support line and the Level 3 tech said " When we reflashed your software, it locks your phone into the T-mobile network" and that was after she went down the hall and consulted with the "developers", Samsung tech support is a Joke. One day I'm gunna root this thing!
Thanks Again Guys.
And to the XDA moderator, sorry I posted in wrong section initially, rookie mistake..
Anybody know how to remove this lock symbol? How to re-lock the bootloader again?

several ideas, what error did it show? what is shown in device manager when you plug your phone in the pc in bootloader?
edit: how did you unlock it?!
Try this, these guys do a great job if breaking things down.

When I go type in 'fastboot devices' or 'Adb devices' it says
"list of devices attached:" and nothing underneath it .....
I have tried updating drivers via PDAnet .... still nothing.
the drivers I have are 'ADB interface'.
Am I missing drivers specific for bootloader or something??
Basically, the phone wouldnt restore or factory reset, so I decided to root it? so I found a new '1 click root and recovery'.
Once I run the script, it unlocked bootloader and also reset my phone which worked great. Only thing I want to do now is remove the open padlock icon on the google screen (which I think is by re-locking bootloader) but when I put in the typical 'fastboot oem lock' nothing happens .....
Much appreciate the help, thanks.
You got to remove everything "custom" (cwm recovery, user roms etc) from the device before you can lock the bootloader again.
When you are trying to lock your bootloader it doesn't do anything because your device isn't correctly recognized by windows, this is prolly due to missing/wrong drivers (try uninstalling old ones and then follow the unlockr guide to rooting your phone/installing adb, http://theunlockr.com/2009/10/06/how-to-set-up-adb-usb-drivers-for-android-devices/).

are you positive sure that i can't lock my bootloader with customs kernels, roms or recoveries? i don't think that's entirely true!

what is your phone 4g or gsm?!
Hello all, I entered into recovery mode and got this warning today. http://i.imgur.com/CHya85E.jpg
For more info, I updated the other day to 4.1.2 and it removed my root access. Now, I was simply trying to remove the SuperSU app by going into recovery mode (don't know if it can be done there or not). Any help is extremely appreciated.
bootloader is locked. search around for an answer or someone will post it for you. I'm not the best at describing how to do it.

Okay, thanks. Whenever I reboot my phone, there is text that comes up and says "custom" with an unlocked lock symbol. Could you point me in the right direction with this? Am I not able to go into recovery mode without the bootloader being unlocked?
I have the exact same issue. It came right after I upgraded Recovery to the latest Touch version. I am also on 4.1.2, but have been there a couple of weeks and have had no other problems. I don't believe I lost root with the upgrade.
If the boot loader has been relocked somehow, how can we fix it without being able to boot the phone? All attempts to boot including volume up/home/power, volume down/home/power, and home power just end up with the Verison message. It appears impossible to boot to recovery or even start the phone. I am lost.
See my thread called: “System software not authorized by Verizon Wireless has been found on your phone.” I also could not reboot the phone to fix it.
Some great info was posted there that enabled me to escape from the Verizon prison
My HTC One mini swtiched off a couple of days ago and since then only load to bootloader menu no matter what I click or do. It goes also automatically to this screen as soon as I plug it with the charger even if did not press the on/off key.
I tried to unlock the bootloader according to the instructions on HTCDev.com site. Everythings work till the last step, as no menu appear on my phone asking me if I want to unlock the bootloader or not.
I also tried to use RUU to install a new Firmware. The phone showes a black screen for a couple of seconds and then restart again to bootloader screen. I got an error afterwards.
The phone was running on a stock firmware, no root, no custom recovery, or any other thing.
Can anyone help me to solve this problem. It seems my phone has no OS or something like that.
PLEASE HELP

I seem to be in the same situations... although I got to it in a different way. Where did you download the RUU from? is it version-main: 4.14.401.2 or higher?
Try: rootwiki dot net and search for htc one mini bootlocker unlock....this helped me to UNLOCK and put TWRP recovery on it... maybe it gets you a step closer.
As per title, it just happened while I was using the phone while charging. Trying my luck as I'm not in the country(Australia) that I bought my Pixel from. Grateful for any suggestion that the sub can provide. Non rooted stock rom
You're only able to get into bootloader and that's all? I would suggest unlock the bootloader, a factory reset will follow. Try rebooting after that. If that doesn't work, at least your unlocked and you can fastboot boot twrp and reset that way or flash a stock rom. If nothing works you "may" have a defective device. I'm no expert but I would try those things first.
Yes only bootloader. What you have mentioned do not require recovery mode right ? Cos I can't boot into it. Thanks for your reply

The bootloader would have needed to have been unlocked already.

no it doesnt, I suggested unlocking the bootloader first, that way it factory resets. this might fix the problem, if not its unlocked so he can flash the factory image.
Bump? I'm having this problem as well.
Same here. How would we unlock the bootloader of the phone when it's stuck in either a Google screen the reboots over and over again, or the bootloader interface (that won't load recovery)? Sorry about the noob question, but I'm not sure how to do it.

I'm having the same issue. My wife's Pixel entered a continuous boot loop today. It only loads the white screen that says "Google." I can enter the bootloader, but when I select "recover," it goes back to the bootloop. As far as I know, she is on Android 8.1, debugging mode is off and the phone is 100% factory.
If anyone has solved this issue, it would be greatly appreciated!
Thanks
has anyone figured this out?? this happened to me today, i was using the phone, the poof it restarted itself and stayed in a boot loop. i can get into the recovery, i tried wipe/factory reset. any suggestions? google told me i need to send it to whatever company to get it fixed or get a new phone. verizon told me to go through insurance. insurance told me to go through verizon because i may be able to use the extended warranty. went back to verizon but they wont take it because the screen cracked a year ago. its not a deep crack and it didnt affect the phone at all, never had an issue. so now i go back to assurion and now they need an affidavit about my screen being cracked. im at a loss.... i havent rooted a phone since my droid x, then s3 days. so im essentially new again!
Same issue here. Phone starts on the bootloader (shows device is locked), but won't start recovery or boot any further.
I'm guessing it's time for a new phone? I hadn't taken the Android 10 update yet, so it was running Pie.
[edit] it's dead - won't let me unlock bootloader or switch boot slots

I had the same thing happen yesterday (not long after the Android 10 update). I was finally able to get it to boot after multiple tries and it stayed up long enough for me to enable "OEM unlocking" in Developer options. Now at least I have the option of unlocking the bootloader and re-flashing the OS with an image directly from Google.
Has anyone been able to get past this problem by reflashing the image? I suspect the underlying problem is some kind of hardware fault with eMMC, DDR, or the SOC itself.
One other interesting behavior I noticed is that the only way to shut it down and stop the bootloop is to select the "Power off" option in the bootloader menu. However, if I plug it in to charge when it is fully powered "off", it will start up the bootloop again.
Same sitution here. A couple of days after installaing it suddenly went inte a G-bootloop frenzy.
Erratic though, sometimes I could boot up (2-3/40 boots) but then it froze and started again.
Also Recovery and Safemode is very hard to get into.
Got in once or twice out of 100 boots, Bootloader Fastboot is generally reachable though.
It exhausted the battery and now I'm holding off trying to interfere, until I get more info off the net.
I've had some troubles trying to root my new phone, as above mentioned in the title. First off, when I try to boot into recovery mode via "adb reboot recovery" command, the phone restarts into a black screen with a dead android with a red triangle and 'no command' below. I haven't yet attempted to actually root my brand new phone yet because I wanted to backup my entire phone (stock ROM/Firmware, etc,.). I am afraid I will end up bricking it and have no ways to back it up. I had the same issue with my older LG G5 with the dead android. Why is there no recovery? And why have I been able to easily backup and root older phones from 2012 from LG but not my newer models?
It's really frustrating.
BTW, I posted this thread in the wrong area and I cannot find an option to delete it or move it to the Developers Section, my bad.

The same thing happened to me. I was hoping to find a way to unlock the bootloader but unfortunately, I can't find any way at all. I was also trying to find a way to boot to recovery mode but the controls are not the same as the other Nexus, Pixel & Android One devices out there. When I press the power, it automatically restarts back to the full UI.

Have you tried the simplest 'fastboot oem unlock' command (having checked the Allow OEM Unlock option in Developer's option; most Android One devices' bootloader can be unlocked this way)?
If it doesn't work, how about the below method, which I believe is the 'official' LG bootloader unlock:
https://www.getdroidtips.com/unlock-bootloader-lg-g7-thinq/
I don't own the LG G7 One, am hoping to, if the bootloader can be unlocked and Magisk be installed.
All the best

Done all of that. Unfortunately, the "adb reboot bootloader" command does not take it to the bootloader screen. It just simply restarted the device.
