Hello everyone.
I am trying to get into the bootloader, so i will be able to use fastboot commands.
Prior to post here i made a thread in the [HELP THREAD] but unfortunately since the person that tried to help me did not had this device, he couldn't help me, thus i'm posting here
So, first i tried to get into the bootloader by pressing the physical keys:
if power button and both volume keys are pressed i get into Android System Recovery(3e).
if power button and volume down key are pressed i get into meta mode.
if power button and volume up key are pressed i get into factory mode, which is entirly in chinese.
in all 3 occations, fastboot devices command did not reply anything....
Now the device is recognized by adb (i made the udev rule for it), all commands are working as should except one.
all except one: "adb reboot-bootloader" or "adb reboot bootloader" or "adb reboot fastboot" do not do anything. they just reboot the device into android os.
even "adb reboot recovery" works correctly...
Lenovo S820 is a new device. it was released in 2013, is it possible that it doesn't have proper fastboot mode??? or is it possible that it needs to be unblocked in some way???
What should i do?
P.S.
Android system recovery <3e> options are:
reboot system now
apply update from ADB
apply update from sdcard
apply update from sdcard2
apply update from cache
wipe data/factory reset
wipe cache partition
in Meta mode just get this: Have been in meta mode, long press the power button and the normal boot.
factory mode (which is completely in chinese) has 8 options.
-EDIT-
I am 100% sure that i found the translations of the 8 options of the factory mode:
Manual Test
Auto Test
Item Test
Test Report
Debug Test
Clear eMMC
Version
Reboot
Any help at all???
What did i do wrong? why no one is replying?
Does the need for the same device is so great???
Isn't it a bit of generic question at all???
I don't need a -like- guide how to do it, i just need some infos, tips and guidance.
I am new to android os, i don't even know what to search/look for, so i can start solving this issue...
HELP!
I need somebody!
HEELP!!
not just anybody
HEEELP!!!
you know I need somebody
HEEEELP!!!!

My s820 is not broken. it's working like a charm.
my problem is that i can't get into the bootloader.
Is there a chance that the bootloader is blocked?
I also, honestly, do not understand why no-one is replying, i am not asking for a how-to guide, just for some tips/infos so i can start investigating how to get into the bootloader....
i know hoow to unlock bootloader in lenovo s820

Hello. In order to test a custom recovery for LG K420n I have to enter fastboot mode and then use the "fastboot oem unlock" command to unlock bootloader. The problem is I cannot enter fastboot mode. I tried all the possible commands and button combinations (http://www.hardreset.info/devices/lg/lg-k10-lte/fastboot-mode/). Anyone can help?

the trick is to completely power down your device, then Hold down the volume up button (or down perhaps. i don't remember exactly) and then plug in the usb cable at the same time.. I figured it out when i was trying to root my device a few months ago and completely messed it up before using the lg pc bridge to recover it again

I tried that many times already. I need to unlock bootloader to enter fastboot but I can't enter it because of locked bootloader...loop.

No. Locked bootloader doesn't screw you. It's able to boot into bootloader/fastboot mode even if it's been locked.
-power on device presing (vol- & power) until logo image appear, release and press again power key by the second
-format device screen apper.. chose : format yes , confirm
-just appear android image formating.. press the 3 key alternatively
-then enter to stock recovery ; and u can chose fastboot or sideloader mode
* i dont know the exactly combination key press. but u must try a couple intents..

It might be easy in MTK but not in Qualcomm lol. We even tried "adb reboot recovery". It just shows a dead android symbol. But even randomly pressing those buttons doesn't allow us to go into recovery. MTK users have a upper hand lol.

Hi!
I have a LGK10 420DS (m216) MSM8916 Indian version I am unable to boot into bootloader or recovery by using adb / fastboot or by volume and power kay, as you are aware LG is not supporting any software update. I want to flash CustomROM and trying to unlock bootloader with different method but unable to enter in recovery, plz. some one can help out.
volume - whilst pluging usb into computer = fastboot mode
volume + whilst plugging = download mode
this works in new models, tested in a lg aristo 2
Please help me to delete this post. i find a guide in my language. thank
Dear fellows,

My zf2 550ml is in android 5.0.
i tried to flash MMbootloader <https://forum.xda-developers.com/showpost.php?p=68806518&postcount=117> to up 6.0 rom. After that, i lost the recovery, cannot access by hold power and Vol +.
Turn off the phone and on again, there is no boot screen or logo. The phone can still boot to android and work normally and still see my phone in adb devices.
Thank.

what every firmware you are currently on.. extract firmware zip file and copy ifwi, recovery, boot, droidboot, splashscreen images and paste those images in adb fastboot toll folder
now in adb fastboot tool folder move your cursor to and empty place hold shift and right click. find option open command windows here. now run following commands
fastboot devices ( to see if device recognized)
fastboot flash splashscreen splashscreen.img
fastboot flash ifwi ifwifilename
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash fastboot droidboot.img
fastboot reboot bootloader
now use volume button to find recovery mode option. click power button to enter recovery. you will enter recovery
( note: if you see an error screen with android logo. at that screen click and hold power button and then click volume plus and release power button you will enter recovery)
hello everyone,i have a g710n that reboots when attempting to enter fastboot/bootloader.
any idea on how to root the phone with magisk/relock the bootloader?
i bought the phone unlocked and rooted with magisk but i accidentally formatted the phone and now magisk is gone
bootloader is unlocked
i can enter into download mode and stock recovery but not fastboot/bootloader mode(restarts whenever i try to do so).
tried both physical combination or adb reboot bootloader,same result.
software version g710n20c
model number lm-g710n
I didn't made this tutorial, all credits to user 机锋网友8051_ABD
LGUP Dual patched and other files You will find in ULM 21d + 20e how to root thread.
0. Shut down, press and hold the volume + insert the computer data cable
1. Download mode, G710ULM20e, partition dl select all, press and hold the volume + again to enter the download mode
2, download mode, G710ULM20e.kdz, and re Volume + enter download mode
3, download mode again, G710ULM11g_01_NAO_US_OP_1112.kdz, dl: boot_a + boot_b, press and hold the volume-and power button to confirm twice after trying to enter dual-clear mode, but will only enter fastboot
4, fastboot mode, fastboot flash boot_a ulm20e_magisk19300_twrp_op_unlocked.img
fastboot flash boot_b ulm20e_magisk19300_twrp_op_unlocked.img, press and hold the volume + after entering the download mode
5, download mode again, partition dl G710ULM20e.kdz, select all and uncheck boot_a, boot_b
6. The first time you enter the system, you may not find the mask magic. Restart the system
.After entering the system a second time, there was a license agreement with a Korean version of the operator. After agreeing, I entered the desktop and saw magisk appeared. At this time Connect to wifi, run magisk, you will be prompted to install, agree, and then restart a series of upgrades
To fix Wi-fi:

Yes bro i also please find any solution
You can try volume down+ power button...if it is not working...
Make sure you installed it properly
The command to install recovery is
1."Fastboot flash recovery (img )"
(If u doubt it didn't install try reinstalling and if you already did then skip this)
2.after that type "Fastboot reboot recovery" this will boot your phone into recovery mode.
3.if you want to enter recovery mode again just press volume down + power button
