How to fix security error without having TWRP? - T-Mobile LG V10 Q&A, Help & Troubleshooting

Please help me, I had the ROM from here:
http://forum.xda-developers.com/tmo...-lg-v10-h901-10c-debranded-debloated-t3277305
Then I started playing around with adb and relocked my bootloader without installing anyhing and just running "fastboot oem lock" command
Now my V10 trapped in a loop of security error and wont boot
I can go to the fastboot mode with pressing down "volume down" while I'm connecting the phone to laptop, also have the 3 ".img" files from here
http://forum.xda-developers.com/lg-v10/development/lg-h901-stock-img-files-boot-recovery-t3238638
But I don't know how to fix this!
Never Mind, I fixxed it with running commands from bat file inside the KlicKiTool, thanks to ted77usa

in fastboot mode up volume key not working?

Its not broken as it works to boot up into recovery. I am trying to unlock the bootloader on my blu studio one S0110UU. "Fastboot devices" shows my device so its connected properly Any help would be greatly appreciated. "Fastboot oem unlock" shows the confirmation screen but only the volume down button seems to work and get a response.
Also when trying to sideload in adb or flash in fastboot I consistently come across the error "Could not find "META-INF/com/google/andriod/update-binary in the zip file" Am i not using the correct file or something?

I have the same problem with Lenovo C2 phone. R u find the resolv alredy?

Newly rooted Moto G4 cannot enter bootloader or recovery, please help!

I am very new to this, I rooted my Moto G4 and now I need to download SUHide in order to play Pokemon Go. When I try to enter recovery via my fastboot/abd folder I get a < waiting for any device > message. When I hold down the power + volume down button my phone just turns on as normal without entering bootloader even though my bootloader is unlocked. I tried downloading an app that loads recovery for me but when I tried that I got a "no command" screen with a little green robot.
From what I've read, it's possible I didn't flash my trwp properly? I don't know how this is possible since I just rooted my phone. I would appreciate some help, I'm afraid to take any random guesses at the risk of ruining my phone. Sorry if I'm missing something obvious or not giving enough info, I'm not very tech savvy.

Try power plus volume up button to go to fastboot mode.
If it not working then connect your android to pc and enable adb. Type "adb devices" enter then type "adb reboot bootloader" and enter. It boots your android in fastboot mode.
If adb commands not working then install adb and fastboot drivers and try again.

In most devices, volume up + power boots up the recovery options, volume down + power boots the device into fastboot mode (volume buttons first plus power, pressing power button first would boot the device normally).

How did you install the custom recovery? Try flashing the recovery.img again (I'm guessing, since you have root, that you did not "flash" (fastboot flash recovery recovery.img) TWRP but just "boot" (fastboot boot recovery.img) it and installed SuperSU).

Okay, so that did work, and I was able to enter fastboot mode. However, once I scrolled down to "recovery mode" and tried to enter, I got the same "no command" screen.

I used the official moto g4 root guide on this website to root my phone and I'm pretty sure I booted, not flashed, the recovery img (mine is named twrp-3.0.2-0-athene). So, I tried using the command you provided to flash the recovery img and I got a < waiting for any device > message in the command prompt. My phone is plugged in and my recovery img is in the adb / fastboot folder. Any idea what this means? Thank you for the help guys
edit: If it helps to know this, my phone has usb debugging enabled and it is recognized by my pc. I type adb devices and my moto g4 serial number does indeed show up.

If you are trying to flash twrp recovery on your android then rename your twrp to recovery.
Boot your android in fastboot mode,
Navigate to folder that you have recovery. Press shift and right click and click on open command here and type "fastboot devices" and enter
"fastboot flash recovery recovery.img
It flash your recovery to your android.

Did all that, getting:
(bootloader) slot-count: not found
(bootloader) slot-suffixes: not found
(bootloader) slot-suffixes: not found
(bootloader) has-slot:recovery: not found
error: cannot load 'recovery.img'
Also, per the suggestion of other users on these forums, I tried to hold down power and press volume up during the "no command" screen after attempting to enter recovery. That sent me into Android Recovery but it's not the twrp platform I used when originally rooting my phone.
How did you unlock the bootloader? have you tried: fastboot oem unlock?
You need to "allow oem unlocking" on developer options (which I guess you already did). Then reboot in bootloader: (a) adb reboot bootloader. In fastboot, you need to unlock the bootloader first: (b) fastboot oem unlock (or unlock-go). Then you can try to flash that recovery.img: (c) fastboot flash recovery "name of the file.img"
edit: fastboot oem unlock restores the device to factory settings. You need to configure and enable again "usb debugging" and "oem unlocking" (which are disabled by default). You can then proceed to fastboot flash

Stuck in bootloop after flashing custom recovery. Please help.

I ported TWRP using Android kitchen to flash to my device (Coolpad 801es) since there isn't an official version. For some reason, I can't seem to get fastboot to play nice with my phone (see my earlier post) so I used flashify. On reboot i'm stuck in a bootloop. I did have the foresight to back up my stock recovery with flashify and transfer it to my PC first, in case something went wrong. Now, I can't boot into recovery at all and ADB isn't working since the phone isn't being recognized by my PC when I plug it in. I just want to flash the stock recovery back and fix this. I can get into fastboot, and the PC does recognize the phone in fastboot, but when I try any commands it just hangs at waiting for device. I've googled but every solution i've seen for fixing a bootloop tells you to boot into recovery to do so.
Can someone please help me out?
UPDATE:
Upon further research, I discovered the reason fastboot commands weren't working is because my phone apparently isn't whitelisted in the fastboot exe. However, if I type Fastboot followed by -i 0x1ebf the commands seem to work. Using this method, fastboot devices lists my phone and fastboot reboot reboots the phone.
I think i'm on the right track, but when I try "Fastboot -i 0x1ebf flash recovery (path to recovery.img)" the terminal shows "sending 'recovery' (10240kb)..." and nothing else. No progress indicator, and i've waited 10 minutes for it to complete which should be more than enough time to flash a 10 meg file, but there's no change it just sits there. Like I said, I think i'm on the right track but I could REALLY use some help. I can't be the first person on here with this problem. Can someone, anyone, PLEASE help me.
So, more Googling would indicate that either i'm not using the correct USB port, or that my bootloader is locked. I have tried all the USB ports on my PC (front and back) as well as two different cables, no joy. As far as the bootloader being locked, the phone is rooted which I thought meant that the bootloader is unlocked as that is part of the rooting process. I try "Fastboot oem unlock" to check but I just get "failed remote no such command unlock" and there is no OEM option under developer options on this phone. I'm trying to piece this together but I could really use some help.

Lenovo x103f unlocking bootloader issues

Hi guys,
In the past days i've been troubling my head with trying to unlock the bootloader on my lenovo tb-x103f, but cant seem to enter fastboot mode
I've been using this guide as reference, among other searches from all around, trying to work around this, but cant really seem to come to the bottom of this.
from cmd
adb recognizes my device
"adb reboot bootloader" tablet just boots into the startupscreen
"fastboot devices" somehow "confirms" that im in fastboot, even tho Im acctually not (right?)
"fastboot oem unlock-go" finishes, and says its successfull, but nothing happens (obviusly, since its not acctually in fastboot mode)
from there it just sits there, and nothing happens. have to reboot it myself, either via cmd or the button
why is it not entering fastboot mode? is there any fix for this?
This is getting really frustrating as I just wanna root the tablet and most likely install lineageOS, or some other custom ROM..
thanks in advance
If you can reboot it with a command than you are connected in fastboot mode. It sounds like you have unlocked you tablet. Enter fastboot mode through adb again and try "fastboot oem device-info"

Nokia 1 (TA-1047) "No Command" screen and OEM unlocking issue

Hi, My Nokia 1 (TA-1047) is now in "No Command" mode.
I installed TWRP recovery previously and tried to root but failed. Then I installed stock recovery and phone started normally. As the phone started normally, I locked OEM through Fastboot mode and disabled OEM unlocking from "Developer Option".
But while installing "system update" from "Settings", it showed error and went to "No Command" mode.
Now I'm unable to flash anything through Fastboot mode because the OEM is locked. Also I'm unable to change OEM unlocking from "Developer Option" as the phone is not starting.
Is there any option to unlock OEM without the help of "Developer Option"?

Edit. Okay, ignore most of what i said down there as after re-reading your post you seem to have a grasp on fastboot, the no command bit still applies though i think
"No Command" mode
If your talking about the recovery with the android image in the background, then there might still be hope, for some reason, the recovery starts up in this mode, showing the "no cammand" message, its fiddly, but you have to press the power button and either volume up or volume down repeatedly, in the end i was button spamming all the buttons and eventually the recovery menu showed up. Carefull to stop pushing buttons when the menu shows up as the buttons are how you navigate(v+,v-) and choose options(power button)
Whether that gives you any options i dont know, you could try a factory reset from the recovery menu, i suppose, or try the posted ota in the other thread if nokia has`nt released official firmware, although im not sure if you can use stock recovery to flash unofficial firmware, best bet is to try and boot into fastboot and use adb on another computer to flash the firmware that way, assuming the firmware files are available.
Most android devices have a way to boot into recovery or fastboot/bootloader using hardware keys
Quick google found this (works?)
Power off
Connect Micro USB to computer.
"In the next step hold down Volume Down + Power key for a short while"
Let go of the buttons when fastboot comes up
Using the computer with adb installed, go to a command terminal and type "fastboot devices" without quotes, you`ll know everythings working if your the device is listed in terminal after typing that command. From there look up fastboot flashing firmware or something to that extent, this is assuming you managed to find the correct firmware for your device and have it stored in your computer
I`d be real carefull here with fastboot, flashing wrong image file could make things much worse, at least it seems you can boot to recovery, so hopefully a factory reset fixes things, use fastboot as last resort i.e if its new job is a paperweight, as i dont think theres any particular guide on doing this specifically for the nokia 1, but i havent checked thouroughly so i could be wrong, take a look and see..............
And let us know if/how you managed to get it working
Goodluck
