Solution: http://forum.xda-developers.com/one...bootloader-locked-t3212187/page2#post63494201
================================
Hello,
This afternoon, I was preparing to flash Oxygen OS 2.1 through twrp but I wanted to make a backup first. Attempting to load up twrp by holding Vol- and Power, my OPT flashed the starting frame of the boot animation for half a second before turning off. This repeated every 5 seconds. I could still boot OOS normally at this stage.
I decided to reflash twrp so as to make the backups, but on attempting to flash it, I saw that my bootloader was locked. So into fastboot mode I went, but trying to unlock it, it did the same as trying to get into recovery. As soon as I sent the command, "fastboot oem unlock", the screen went dark, flashed the starting frame for the boot animation, and promptly when dark again.
I now can't boot up normally, nor can I enter recovery. I can access fastboot mode, but I can't seem to make any changes.
I've attempted to use this solution as well as several other similar ones with no success.
I've had my OPT since 17th of August with absolutely no signs of trouble until this afternoon.
To me, it seems like it could be a hardware issue, but I'd hope it would last more than 40 days.
Any suggestions?
Thanks.

What were you doing before it occurred? Perhaps we can work out the cause.

I'm not sure what I was doing, I was going to flash different ak kernel as my wifi didn't work.
HOWEVER
I read someone suggesting if you still have bootloop after trying the qualcomm recovery tool, try booting to fastboot and use: fastboot continue
my opt booted nicely to hydrogen os and after I shut it down it no longer bootlooped and I was able to get to recovery.
I'll post this to your reddit thread too, maybe it might help somebody one day, hopefully this works for you too

Mate! that worked for me too!
However... It only seems to skip the bootloop for that power on. After power off, it returns to the boot loop. I also still can't unlock the bootloader and can't access recovery.
But at least it can boot into OS with fastboot continue!
Thank you.
Weird, after the first successful boot I rebooted and a chinese menu prompted me if I wanted to unlock the bootloader, and I did.
Maybe you should try different recovery packages.
But I'm glad to hear you at least got past the boot loop

Can't flash a new one since the bootloader won't unlock :/
I guess the phone is in working order at the moment, I just can't let it get turned off without my computer next to me...

Nono I mean different qualcomm recovery packages, the ones with MSM8994DownloadTool, I also replaced the stock recovery in the qualcomm package with twrp just in case if that matters

Ahh, do you mind linking me to the one you used?
I think I used this: https://mega.nz/#!EsNQHKab!ifATzg4rxxBniPad0iyxANqlN8cZpUx2MVWaZgEhrD4
but it might have also been this: https://drive.google.com/file/d/0B14IjYN3PtxcSlJ5aGQxX3JERHM/view?usp=sharing
It's also worth mentioning I flashed both a few times before I tried the fastboot continue command so try both a few times and see if that helps, also I replaced the stock recovery with twrp in both recovery packages before flashing.
Edit: And best of luck, I'm rather confident your OPT is going to work properly again.
Boot Loop
I got the same problem.
Phone is rooted and i can't unlock it in cmd, just reboot itself when i try it.
The only way for me to even start the OPT is to (volume+ and power), to get to fastboot mode, then run "fastboot continue" twice in cmd.
If i reboot the phone it get cought in a boot loop where i can see the logo, reboots about every 2 sec.
Is there a solution for this? I've been searching 2 for two days now.
I don't care if i have to reset the entire phone.

I got TWRP installed but its unreachable, volume- and power ends in boot loop.
I can´t install anything when the phone is locked.
I even tried a Factory reset, boot loop and no change when i got it up again.

I finally got my OPT working again, tried Qualcomm recovery tool, wasn't able to complete the "MSM8994DownloadTool"
So i downloaded "A2001_14_A.03_150805" in a guide from technobuzz.net/unbrick-oneplus-2/
A similar but it does a entire wipe of the phone, nothing left at all. WARNING!
But i was okey with it.
Well the phone was in Chinese when it was all done but to change language was no problem.
I finally managed to solve it on mine. I had been cautious over the past weeks to not let it run out of battery or get turned off while away from my computer as
Code:
fastboot continue
was the only way I could get past the boot loop.
My core issue to solve was that I couldn't get it recognised as the USB Diagnostic 9006 under Ports in Device Manager. I installed the driver from here manually by right clicking the /qcser/x64/qcser.inf file and selecting install from the context menu. Then, I powered off my OP2. While only holding Vol+ (not power or Vol-), I plugged in my OP2 to the computer and it was finally recognised as the 9006. Then using the recovery tool from the prior link, it installed and rebooted my OP2. The moment of truth was when it rebooted and didn't enter a boot loop!
Then with the Chinese recovery prompt, I selected the top/first option and it brought me to the welcome/first setup screen of OOS.
It wiped the internal memory, and installed OSS 2.0.2 (don't know if coincidence or not as that was my prior OS as well). Now to install twrp and update to the latest OOS hopefully without a hitch.
Happy to finally know it wasn't a hardware issue like a failed eeprom or a dud nand controller as my prior phone (Samsung Note 10.1) died to a failed nand controller as well.
Will update with news of twrp and OOS, but I feel that should go smoothly now. Thanks to the others that helped in this thread too!
Yeap, all good!
Flashed official twrp through fastboot and batch installed OOS2 through 2.1.1 patches and SuperSU. Everything working like new!
Phew.

same problem here and cant find solution ...
I had the same issue. when you press to reset button when the phone boots it should reboot and for a short time go to recovery and try to write some commands, right? if it does like mine did then what i did to fix it was boot up the phone and wait for the page saying encryption unsuccesful to popup and on the computer have the adb reboot recovery ready to go so when you press the reset button and the recovery menu pops up press enter on the computer before it goes away and it should send you to the regular recovery menu. from there you should go back to wipe and press the format data button where you have to type yes to erase everything. let me know how it went.
you will have to reflash the supersu but it should now be working like it should
Flash the latest su and your fine.

Make sure your on charging mode and you have adb debug enabled
send the adb reboot recovery command as soon as the twrp connects to the computer. as soon as you hear it connect to the computer it should work if your drivers are working.

What screen are you stuck in? Do you have adb up and running?
Same as before Encryption unsuccessful. I was able to do the trick, got into two and wiped data. Then rebooted to system and it went right back to that screen. I've tried 100 times or so to get back into twrp with no luck. I hear the computer recognize the device when it goes into twrp for 2 seconds after you click reset. Not sure if that means add is up and running or not.

Had the same problem and could not for the life of me do the adb thing. Someone here stated something that I thought I'd try: Press volume down while plugging in the phone to get into fastboot. In a command window issue "fastboot oem lock" (this will relock the boot) > Let the phone reset and you'll see the "Phone corrupt message" > Plug the phone in again to do a fastboot and issue "fastboot oem unlock" > Take the battery out let the phone boot and BAM-E WHAM success!
btw. I followed the steps here to do the whole root thing with Android . how (google "how to root the v20")
I think the "data" wipe did this and according to this site it's not a necessary step so skip it.
This option works!

I go my T-mobile LG V20 H918 on 11/23/16 and sure enough, I followed the same thread as listed above where it added the step of "data wipe" crap. I was caught in a bootloop, where phone kept bootlooping back to the "reset to factory." The other method of entering the adb command at the right time was more frustrating than anything. (I never got it to work). I spent all day yesterday trying to get this phone working. I re-read (x30) the above thread and on the first attempt it worked. I did not get the "Phone Corrupt Message," but I went ahead and entered the "fastboot oem unlock" and the F#$king phone finally reboot to the setup initial screen. It wiped everything, but having a phone working rather than a nice $800 paperweight, I wanted to kiss SkyHusky for sharing this simple method. YOU ARE AWESOME!!!!
By the way, since I am a glutton for punishment, I followed the steps to root again. After flashing the SuperUser, I rebooted to System. I was at the initial setup screen. My phone is rooted, has TWRP, and SuperUser! As soon as I got the phone working, I went back to TWRP and made a BACKUP!!!!
It is amazing that every time I f-up a phone, I can always come to XDA and get a solution. THANKS GUYS!

No problem!! Also I forgot to add I only rooted afterward and didn't try to install a ROM or anything. I would think you risk danger with some ROMs without that decryption thing turned off. So maybe in the short future there will be better fixes.
Hi,
Yesterday my G4+ had a strange behavior.
I had a notification I can't dismiss so I decided to power off my phone to restart it.
When I power it on, it went in boot loop, ending on a black screen with a droid and "No command" text.
I tried to reboot it several times without luck, always coming back to this screen. Then I choosed factory entry (don't remember the exact name) and it finally boot normally, but with a new app "CQATest" I never seen before. Besides that, everything seems to worked as usual.
I plug in to charge but the battery stayed at the same level.
I decided to restart it again to fix the charging issue and it worked without any problem, and now I'm able to charge it.
My phone seems OK now but I'm a bit worried by what happen. Before I power it off the first time I was zipping files and doing intensive stuff with emulator, can it be the cause ?
My phone is on stock Nougat ROM.
Sorry for my english, it's not my main language.

actually it's not a bootloop, it's stock recovery. your phone was started into recovery..
OK thanks for the explanation. But why did it start in recovery ? And what can I do if it happen again ?

I can't say what happened, may be something bad processes running in background or use of bad apps caused hanging.
if it happens again, then just restart to bootloader and start from there, it always work for me when my phone starts booting into recovery instead of system (it happens to me because of flashing custom recovery and all )...
In extra you can try following commands,
mfastboot oem fb_mode_set
mfastboot oem fb_mode_clear .
Help: G4 Plus won't start after accidentally hitting "Open" on icon pack install.
I got this phone literally yesterday, it's unrooted, worked perfectly fine until my hand slipped when installing an icon pack from the play store and I hit "Open" - the phone immediately crashed, and now will not boot. I've tried using standard power on, powering on through the recovery bootloader, and entering recovery mode through said bootloader, in every instance it displays the Motorola startup screen, plays through its sequence of animations, then as soon as the Lenovo brand icon shows on screen emits one long pulse of vibrate and then turns off again.
I can't pull the battery because I don't have the required micro-hex screwdriver. Can anyone help?

can you reboot to bootloader and start recovery? Then clear cache and see if it helps to boot your device? Or if not make a factory reset if it won't help. Maybe the icon pack screwed up something.
Report back. After that, if nothing worked, you can try this:
Is your device recognized by fastboot? If yes, try "fastboot devices" and see if it shows serial number.
Then try to flash the latest stock in the following guide rom if you have one of this devices https://forum.xda-developers.com/moto-g4-plus/how-to/stock-rom-npjs25-93-14-4-march-1-t3608138

Hi, thanks for responding. After four or five attempts to boot into recovery it succeeded; wiping the cache did nothing so I did a factory reset, which worked and now the phone will boot to the setup stage. Unfortunately now I'm getting "The device was reset. To continue, sign in with a Google Account that was previously synced on this device.", which after googling seems to be a security feature - the problem is it doesn't accept the google account credentials, every time I enter them it just cycles back to the "This device was reset..." screen again.
I know I'm not getting the details wrong since I made the account specifically for the phone and have the details written down. Any suggestions on how to proceed?
EDIT: Actually nevermind, I managed to follow along with a tutorial on how to bypass it using MotoService & ADB. Thanks again for replying.
I successfully rooted the device and until recently I wanted to unroot the device, so I uninstalled Magisk.
However, after doing so my device rebooted into a black screen and the only response I got was a vibration when I tap the right side/edge of the screen or press the power button.
I tried pressing the Power button + Volume +/-, and was able to enter recovery and fast boot mode. However, I tried wiping cache, resetting, and formatting, my phone would still reboot into the same state.
When this problem occurred I had 30% battery and I also tried MSMDownloadTool for 6T, but my computer simply does not recognize the device. My device is only two weeks old.
Any help would be appreciated.
