[GUIDE] How To Enter Fastboot Mode

This is the method tried on H815T model. But I think this should work with also other H815 models (other devices cannot say). Thanks to @autoprime, @thecubed and @Unjustified Dev for this.
Disclaimer: I am not responsible if your device gets into any more trouble for this.
Steps:
1. Download & clean install LG Drivers in your pc if u don't have it already.
2. Go into download mode by presing down the UP button and connecting the usb cable to the pc.
3. Go into LG ROOT folder. see this link to download: http://forum.xda-developers.com/android/development/guide-root-method-lg-devices-t3049772
4. Double click on ports.bat to know your COM port. Let's say it's COM4.
5. Open a windows command promt by Shift+Rt Click into the Lg Root folder.
6. Now send these commands:
Code:
Send_Command.exe \\.\COM4
It will reply
Code:
SPECIAL COMMAND : ENTER , LEAVE
#
7. Now command type
Code:
id
It should reply
Code:
uid=(0)root gid=(0)root
#
8. Now type
Code:
dd if=/dev/zero bs=8192 seek=35840 count=5120 of=/dev/block/mmcblk0
It will reply
Code:
#
9. Now pull out your battery, put it back in, go into HARD RESET mode by pressing down DOWN BUTTON+POWER BUTTON together and when the LG logo apprears, release the power button for a second and press it back again.
10. Now in HARD RESET, it will ask you whether you want to reset everything or not. Select "No" and it will take you to fastboot mode.
Special note:
1. @autoprime told me to factory reset everything before starting this whole process. I did as my bootloader was locked. Don't know how it affects in unlocked bootloader.
2. How to get out of fastboot normally: I don't know it quitely. My bootloader was locked, so neither I could flash any system file through fastboot, nor "fastboot reboot" or "fastboot reboot bootloader" worked for me. @autoprime told me to get out of fastboot, manually go into download mode, then pull out your battery and put back in. Actually you can't get out of the fastboot that way until you flash a KDZ.
Thank u. Reply in the comments if fastboot could help you any.

Hi,
Thank you very much for this Guide. Unfortunately, having tried to unbrick my device (H815) previously by hard resetting and not having access to Android to re-activate ADB, the Shell (Send_command.exe) didn't help me (at every command it returns a "FAIL" message, my phone is recognized by Windows by the way).
So I couldn't get into Fastboot by following this Guide.
Hope it works for others, waiting for results!

You couldn't get into fastboot or u couldn't flash anything in fastboot? I cannot make my device recognised in adb too, but it is recognised in fastboot. U need to have the adb and fastboot setup in your pc. But I couldn't flash anything in fastboot as it shows my device is locked although someone said, theoritically it was supposed to flash system files through fastboot.

I couldn't get into Fastboot at all. Any command typed in send_command.exe gives "Fail" as result... Phone is connected in Download Mode and recognized in Windows, DIAG1 port is COM4.

True. I didn't realise that before, so gave it a try. But this may help those with unlocked bootloader.

This does not work for me, I have an unlocked bootloader, but just get the response "FAIL".
And... Why don't you just zero the laf partition instead through an adb shell? What does this do that's different?
If we can get into fastboot, can we then do something like
Code:
fastboot boot recovery.img
to get into a custom type recovery and do a backup? I'm on the AT&T H810 version, locked bootloader, I don't know if that means a big fat NO lol or if this method of getting into fastboot mode would even work on my variant.

no one should be wiping laf or recovery to get into fastboot. it's a dumbed down fastboot that doesn't let anything flash or boot. the directions I gave OP were in a PM as a last resort because he was stuck in download mode with no booting and wanted to try fastboot. It was never meant to be suggested in public to users who might think they can get anywhere with it.

Holly molly sir! You are a legend. Long story not so short. My lg got the bootloop bug. Took 2 months to fix, but apparently they changed my locked to three uk H815 "eu open" motherboard with actually unlocked one. So I was finally able to unlock boot-loader, root and **** up (LOL). Apparently I didn't install twrp properly (you'd think "fastboot boot twrp.img" would not install it but run it once) And i was following this to get Android M on. But it requires reboot before boot-loader is flashed. Right when i clicked reboot i figured it wont start in twrp but in stock recovery. So I couldn't even get proper bootloop, it would cut half way into the LG logo. I reckon kdz-ing would havedone the trick, but god it takes ages to DL the kdz file. So in the mean time i found this legendary post. The odd thing was i had to click Yes, on the factory reset screen, but it got me to "Fastboot mode started" and from there i booted into twrp and finished what it had started, currently its Optimising app 35 of 55. Nice one OP, Nice One!

Hi,

Bootloader unlock and custom recovery

Hello guys. Before you proceed, I'll let you know that I don't own this device. Theoretically these steps should work.
1. Unlock bootloader
Go to settings>about, tap build number 7 times. This enables developer options. Here, select allow OEM unlock and USB debugging. Reboot in fastboot mode (power+vol down). Then go to this site
https://motorola-global-portal.custhelp.com/app/standalone/bootloader/unlock-your-device-a
And follow the instructions. They are pretty straightforward.
2. Install TWRP
Go to
http://lenovo-forums.ru/topic/22535-moto-m-kastomnoe-rekaveri-twrp-otklyuchenie-shifrovaniya/
And download TWRP_Moto_M.img and boot_M_S124.img
In fastboot mode type fastboot flash boot <the name of the latter file image, just drag it into the CMD window from adb and fastboot folder> then type fastboot flash recovery <TWRP file>
Then type fastboot boot <TWRP file> and voila, you are booted in custom recovery.
IMPORTANT: FOR ALL THAT IS GOOD AND FAIR, MAKE A BACKUP OF EVERY FOLDER. IF YOU MESS UP SOMEWHERE, I WON'T BE ABLE TO HELP YOU!!
Now you may proceed to rooting procedures.
Tell me if this works. And before asking any questions in this thread, use the DAMN INTERNET; Google or Bing or Yahoo, whatever floats your boat

If you are unsure of any step, and Google does not help, ask it in this thread and wait for my reply

If someone has been able to root the device successfully, do share with me the system and boot backup made in twrp. I will try bringing up a ROM.
For unlocking just enable it in developers and then

The wrong way to go.
Follow these steps:
In Windows command prompt write adb reboot bootloader. The device will reboot into fastboot.
The following command - fastboot oem unlock. You will be prompted on the phone screen, volume up to confirm, down to refuse. Who decided to change his mind
I waited a few seconds and at the command prompt, I got the answer - OK.
Disconnect the cable from the phone and hold the power button reboot the phone and put aside. He will restart another 2 times, will go to the drain recovery and erase all data from your phone. Therefore, I recommend to make a backup.
You just have to wait to boot the phone. approximately 5-7 minutes.
The bootloader is unlocked.

That's just the point, that you give the wrong information.
You give a link to the unlocking of MOTO devices on the Qualcomm processor, and that method is not suitable for MTK.
I also laid out 100% working instructions.

I read some guides that say you need fastboot and adb. How do you get them. Also to boot in fastboot you need to hold power+volume down or something else?
Thank you for all the answers.
Check If camera 2 API Enabled or Not By downloading Manual Camera From Playstore .
If All Right Mean Camera 2 API Enabled .
If Camera 2 API Not present.
Just Remove Your ADB Fastboot Driver And Download latest Version Adb And Install It Manually.
Then install Camera 2 API With Gcame .
It will Lock Your Bootloader Without Any Issue

Hi,
Someone could say me if fastboot oem off-mode-charge 0 (for power on the phone when it off and charger plug) work on this phone. I want to buy it but I need to know that before.
If someone can test it to help me, the reverse command is fastboot oem off-mode-charge 1 (and the phone charge without boot again).

Hi, try the following:
Power off device (if possible, if not, plug USB and press and hold Power & Vol down for min 10 sec),
then hold Volume down and plug usb . If you succeed, try:
a) fastboot erase userdata
fastboot reboot
If you have BL unlock code:
b) close the bootloader again, it should work if the kernel and recovery are still original. Use command
fastboot oem relock <code>
- try again unlock the BL

Hi, thank you so much for your help. Unfortunately, however, it does not go into fastboot mode in any way and so I cannot test the commands. I'm pretty sure I did a wrong cleaning with TWRP.
