i messed up.. - T-Mobile LG V10 Q&A, Help & Troubleshooting

So i was trying to revert back stock. i flashed a stock rom removed superuser and then rebooted into bootloader via fasrboot and oem lock.
after that, i now get lg security error #9 modified.
i try recovery but that fails with a secure boot error.
i cant get my pc to detect my phone.... is it gg?
or is there button commands to access bootloader manually on startup?

Recovery:
With the device completely off, press and hold the Power and Volume Down button until you can see the recovery mode displayed on the device’s screen.
Download Mode:
1) Power off the phone.
2) Press and hold the Power Button and Volume Down.
3) While holding the Power and Volume Down buttons, insert the USB cable connected to a windows computer.
4) Continue holding the Power and Volume Down buttons until Download Mode is displayed on the phone, then you can release the buttons and unplug the cable if you wish.

To boot into bootloader manually,you hold vol down and plug a cable in with the device off

And if your flashing ANYTHING with oem lock it will fail instantly boot into bootloader and oem unlock then flash all stock files including recovery then relock and you should be good. Good luck

luckily they just gave me a new phone. o.o
ill save this though, thanks!

I cannot find place to type.
It is very possible that the volume up key does the job.
the volume up key doesn't seem to work... any ideas why is it?

Do you mean that it doesn't work when the device has loaded android?
If yes, then reflash the official kernel and see if the problem persisits.
If the problem persists then it is very possible that you have a hardware failure...
If you have flashed my kernel and you mean that you cannot enter CWM by pressing volume up, just press the power on-off key once or two, when the (white)
se logo turns brighter and you will enter CWM.
i mean, i cant get into fastboot mode by clicking the volume up key so i cant flash any rooms
think that i had unlocked the bootloadrer i used the test point method with s1tool( http://forum.xda-developers.com/show....php?t=1285285 ) it didn't gave me any error message, it looked like it worked fine, tried volume up volume down even the home button and various combinations of it... the volume buttons load the CWM and if i restart holding the volume up key it boots into charging mode...

I can't understand a few things about your case.
Have you already flashed my kernel?
What version of CWM are you running?
To enter fastboot mode you have to connect the usb cable to your device,hold the volume up key and connect the usb cable to your computer.Then the led light turns blue...
i didn't flashed the kernel because i can't boot into fastboot mode, maybe because the test point method with s1tool didn't unlocked the bootloader, but it looked like it did?
i am using the cwm version 5.0.2.7

You can enter fastboot mode, even if your bootloader is locked.You can't install custom kernel though.
Dial *#*#7378423#*#*
Go to service info, go to Configuration submenu and check the status of your bootloader.
If the text under rooting status is:
Bootloader unlocked:Yes
then your bootloader is unlocked.
If the text is:
Bootloader unlock allowed:yes
then the bootloader is still locked.
About getting in fastboot mode now.Try searching the web on how wt19i gets into fastboot mode.
Visit this page also:http://unlockbootloader.sonyericsson.com/instructions
mine says Bootloader Unlock Allowed: No
saw somewhere that it means that the bootloader is unlocked?
the only 2 methods that i can find for booting into fastmode is the volume up key method mekes it go into charging mode (it shows sony ericson on the screen as usual then it shows up a battery with a power logo in the middle)and i saw someone say that he entered fastboote by holding volume up + home key and connecting it to the pc, both didn't worked?

Try visiting this page and read carefully the second step:http://unlockbootloader.sonyericsson.com/instructions
Your bootloader is still locked and cannot be unlocked.
Sorry...
This method also work with 4.0.2.A.0.62 version.

Lg optimus ls970 fastboot no power button

basucally flashed a rom and it went bad and my phone wont boot, i can only get it into fastboot but plugging it in and holding volume up and i have no power button, so i cant select boot into recovery, is there any way i can through the cmd?
*edit*
I figured out how to boot to recovery, download a recovery img, and in fastboot cmd you go
Fastboot flash recovery_image_name.IMG
Then
Fastboot boot recovery_image_name.IMG

Depends on which version of the official software/firmware you had installed. You might check out this:

If you were on a KK set up then that recovery won't work.

all i want to know is, when im in fastboot is there some kind of command line or any other way i can select recovery mode besides the power button? my power button is broken, and i cant turn on my phone to reboot into recovery due to me soft bricking it.

So when you turn it off, leave it set there for a bit (guess you would have to let it die at this point...), and hold Volume Up and plug in the USB cable to the PC - you don't get into Download Mode? But as far as booting to recovery without the power button and not able to boot into the OS...I can't think of a way. There are no fastboot commands to get to recovery and without it booting to anything but fastboot, there is no way to utilize adb commands either.

Can't enter recovery due to bootloader warning.. what to do?

Hi,
I just flashed Nougat KDZ on my H850, now trying to root the phone.
What I do:
adb reboot bootloader
fastboot flash recovery twrp-3.0.2-1-h850.img
disconnect cable
remove battery and put back
hold volume down + power
when I see LG, I quickly release power and press again and hold
then this stupid bootloader warning screen appears (that the data can't be verified) and it won't enter recovery..
What am I missing here?...
Thanks!
Never mind, got it.
I don't know where I read about the remove\insert battery thing..
"fastboot reboot" after twrp flash solved it for me.

Stuck in recovery mode

I accidently flashed the lineage 16 recovery instead of lineage 17.1 recovery. I tried to install the 17.1 update through updater but my phone stuck into recovery mode. Neither I can boot into bootloader nor to android. I can''t flash anything. Power + volume down and connect the cable also not working to go into bootloader. Even bootloader option within the recovery also brings me back to recovery mode. ...adb devices command is also showing "device offline". Any help will be appreciated.
you should start from the beginning
is your bootloader still unlocked?

I can't go into fastboot mode. Is there any other way to check it?
Thank you @stukka2006 for replying me. I guess I saved my phone. So here what I did-
1. Extracted the stock firmware (Luckily I had one but can be found in the forum) and copied the dload folder to sdcard (as I was not able to access internal storage). (@stukka2006 your hint to start from the beginning)
2. Power off the phone and pressed Both volume buttons + power button simultaneously. After the vibration I left the power button while still holding both vol buttons till software update screen appears. But software update failed. So I just touched the reboot now option. The phone rebooted to fastboot mode.
3. I installed TWRP but was not able to reboot to recovery through commands and system reboot command brings me back to fastboot mode. So I again power off the device with cable connected and pressed both vol buttons. This time phone showed recovery screen (Should have worked with normal button shortcuts also, I guess) and I flashed the rom and rebooted normally.
Everything is working fine now except that I lost the data.
Happy you got all clear my friend !!!

How do I access download mode with hardware buttons in this device?

I tried going through recovery to bootloader, but that does not put me in download mode. Any other tips except Adb. Just thinking about what I can do in a boot loop or brick except wipe.

If you're in recovery mode, you can use ADB to command a reboot to bootloader, which for most Samsung devices opens download mode as well - the screen is just black instead of green.
Getting into bootloader mode via the buttons depends on the device, but the universal method seems to be this:
Power device completely off, wait a minute or two
Hold both Volume + and - buttons, do NOT press Power
While holding Volume buttons, plug in USB cable connected to your PC
Device should start in download mode.
If you press Power, or connect the USB cable before holding the buttons, your device will just power on.
Going into bootloader does not put me into download. I ahead to use Adb reboot download and you can’t use Adb in stock recovery
