After this message you should
-connect your device with PC, install ADB drivers if didn't it before,
-install LK bootloader and reboot to fastboot mode again (press VOLUME DOWN for FASTBOOT),
-install recovery and reboot to recovery mode (press VOLUME DOWN for FASTBOOT)
-install ROM. In Recovery, Go to (Install from SDCARD), then (Choose zip from SDCard)...
Something like this.

Download mode for unbrick after failed OTA-Flash of knock code

Hi
I tried to flash the knock code for open-devices over a rooted stock rom with custom recovery - so everytime I boot it automatically boots into custom recovery.
How do I enter download-mode to unbrick it using the offline-fix for the LG R&D Test tool? Holding volume up while plugging in the cable boots into TWRP and holding volume up+power also boots to TWRP..
Everything I try boots into TWRP even if it should boot to Download-Mode
SOLVED: (my problem was wrong searches within XDA and Google - "no boot after flashing knock code" isn't "LG G2 download mode doesn't working")
1. Open in TWRP:
Advanced - Terminal - Select / as folder - go to terminal
2. Enter
Code:
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota
and hit "GO"
3. Enter
Code:
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/misc
and hit "GO"
4. Back to main menu in TWRP - hit reboot -> System
now worked...

Bootloader unlocking and rooting method for honor 4x : Step by step

First of all usb debugging should be on in phone (settings>about> tap multiple times on build number to unlock developer option> now go to settings>developer option> set usb debugging on). And don't forget to backup your data (contacts,messages,photo,video etc.)
#STEP 1 : INSTALLATION OF ADB DRIVERS:
Download the adb drivers and follow the method shown in this video www.youtu.be/RDA8PpPSFuk
#STEP 2 : GETTING THE UNLOCK CODE FOR BOOTLOADER :
u will need these
1. IMEI-1
2.S/N (serial number) ...These both are found on removing backcover,written on unremovable battery.
3.PRODUCT ID (Dial *#*#1357946#*#*)
4.MODEL (settings>about)
Get bootloader unlock code on huawei website. www.emui.huawei.com/en/
go to download tab>unlock bootloader>register to make account or sign in with facebook id.
After entering the details of phone you will get 16 digit bootloader unlock code. save it.
#STEP 3 : UNLOCKING THE BOOTLOADER :
Download the adb & fastboot folder.
Connect phone to computer in fastboot mode (switchoff>press & hold volume down key and connect to usb cable>phone will vibrate>release the volume key).
Now open the command window in adb & fastboot folder (Open adb & fastboot folder > Press and hold the Shift key and press right click on mouse to open option menu and select "Open Command Window Here").
In command window type "fastboot oem unlock 11111111111111" (without quotation, where 1111111111111111 is the unlock code you got from huawei site) and press enter. (do not delete anything in command window, start typing from just where the cursor is showing). This will do the unlocking of bootloader.
Now type in command window "fastboot reboot" to reboot the phone. After rebooting, unplug the phone from computer.
#STEP 4 : ROOTING THE PHONE :
I have tried several methods but no one succeed. I tried rooting through kingroot phone app but that too failed. But I rooted my phone successfully with kingroot desktop software (download it from www.kingroot.net ). There is no need to install superSU after rooting through kingroot.
#STEP 5 : FLASHING CUSTOM RECOVERY (TWRP) :
Download the new_lp_twrp_recov.img file and keep it inside adb & fastboot folder. Connect phone to computer in fastboot mode. open command window and type "fastboot flash recovery new_lp_twrp_recov.img". Recovery will be flashed. Now enter command "fastboot reboot" to reboot the phone.

Thanks for sharing process to root EMUI3.1 on CHE1-L04.
Just a suggestion, mention [OPTIONAL] in-line with Step-5. As many people visit here mainly to know Rooting method.
Also it would be great, if you can share StockRecovery image and Kitkat EMUI3.0 Rom! Thanks again.

Thank you

My Moto G4 Plus can't enter bootloader mode by pressing Vol- + Power

Instead, it enters in Factory Mode.
I tried to force it in Fastboot Mode using the "adb reboot bootloader" command in ADB(tried in mfastboot too), but every flash related command always give me "Failed" message. When I turn on "Unlock bootloader OEM" inside Dev Settings, but it auto turn off when I turn off the device.
I can't find a solution. Can anyone help me?

Cannot go into the bootloader mode on my Galaxy tab SM-T285

Currently, I am trying to unlock bootloader using adb.
I installed adb and fastboot and checked everything until the CMD shows my device correctly.
And right after I type
"adb reboot bootloader"
my tablet just restart and does not go into the bootloader mode.
I also tried it manually, by pressing home+up+power button, but it also perform restart and no bootloader mode.
Does anyone knows why?
I checked all the settings in developer mode and cannot figure out why.

You can't unlock the bootloader with adb only with fastboot which doesn't work on Samsung. To unlock the bootloader on Samsung you have to enable OEM unlocking in developer options. Also Samsung doesn't have bootloader mode but instead they have Download mode which you can use tools like Odin or SmartSwitch to flash files. To get into Download mode use the command adb reboot download or use the button combination power + volumn down + home.
