LG G6 H870 only boots in fastboot mode - LG G6 ROMs, Kernels, Recoveries, & Other Developme

Hello,
I tried installing redfox recovery on my H870 and it went well.
However, when I use the key combination for recovery, I always end up in fastboot mode.
I tried re-flashing TWRP from fastboot, went fine, but still not able to boot to it. I always end up in Fastboot mode.
PS: I don't have a OS, so I cannot boot to it either.
Please assist
Thanks in advance

Can I flash a partition using fastboot flash <partition> <filename> which will give me back recovery?

Please ignore: I managed to boot into recovery after I charged the phone for a while

Stuck in TWRP

Hi everybody,
I have used the command fastboot boot TWRP.img on my macbook connected to the MI9 and now I cannot bypass the TWRP screen. 3.3.1-1siankatabg.
I can only have the fastboot mode or the TWRP screen.
My bootloader is unlocked.
I don't have windows.
Thanks for the help;
May be because it's recovery.img and not TWRP.img Try to reflash TWRP (you may try different versions) if you will be able to boot TWRP but not system, reflash your rom, if not just flash fastboot ROM, it can be flashed in fastboot mod.
And i'm just guessing.
Flash TWRP again.
Connect your phone in Fastboot mode and use fastboot commands in this order:
Code:
fastboot flash recovery twrp.img
Code:
fastboot boot twrp.img
And now before u put this command, hold "Volume +" button until vibration:
Code:
fastboot reboot
Then in TWRP if your memory is encrypted, put the password in, and reboot to system from TWRP Menu.
Hi,
I managed to start but I had to erase data
Thanks!

Can't Access Recovery or Device, only Fastboot

Hello,
I deciden to install Android 10 Beta 3 then install a custom rom. I succesfully installed Android 10 Beta 3, and tried to install Magisk as told in here. After the patched boot.img step, my device stopped booting.
When I press Power+Volume Up or Down, it always goes to fastboot mode. I can't boot into recovery from fastboot, I can't boot TWRP from fastboot. I tried:
fastboot oem reboot-recovery
fastboot boot twrp.img
fastboot flash recovery twrp.img
As shown in the image rebooting into recovery always failing. What can I do?
same problem here... were you able to fix it?
You might have to use the QFIL method to get your phone going again. Remember you MUST backup the EFS partition and anything associated with your phones imei and SN

这两个可怕的重锁码吓了我一跳,以为手机没电了。幸运的是,我找到了解决方案。你可能需要找个老股rec,跟着视频操作,不用拆机,重点解压。进入adb文件夹,生效

Hey guy,
My phone was running the rom "UL-ASUS_X00QD-ASUS-AOSP-17.0615.2005.25-1.1.1-user.zip" (downloaded from Asus Web). I tried to install the TWRP ver 3.3.1 unofficial and my phone was stuck on the fastboot mode only.
After a lot of searching on how to fix the issue, I didn't change anything and almost gave up, until I've read this thread.
My Asus Zenfone 8 flip is STUCK in CSC FASTBOOT MODE PLZ HELP!, RAW FIRMWARE ANYONE???
These are what I did to get the phone into the recovery mode:
1. Extract the rom zip file that my phone was running on.
2. Copy the file boot.img to adb folder.
3. On PC, at adb folder enter CMD, connect the phone then type
fastboot -w
fastboot flash recovery recovery.img
fastboot flash boot boot.img
fastboot reboot recovery
4. After that, my phone can be booted into the recovery mode.
Hope you can solve the same problem as me.
Bye bye ...

Help| Can't boot

Hi,
I have Carbon ROM with Android 10,
I wanted to flash Bliss ROM, and it says that I need a rooted device,
So I've downloaded Magisk and follow the instruction, created a boot.img and flashed it in fastboot, then I did the same only with twrp recovery & Magisk, flashed it and now it is wiered and I'm not sure what is the problem,
I have fastboot BUT when I try to perform any command, it shutsdown and preety useless, I've tried from PC, if I try from MAC, I can boot into twrp but every operation is causing the tablet to reboot.. So I can't even flash a stock ROM,
In PC, the recognized Android device (When in fastboot mode) I update it's driver to Android bootloader device
Now, fastboot says: "fastboot: error: cannot get boot partition size"
tried:
fastboot flash:raw boot boot.img
fastboot flash:raw recovery twrp.img
How can I solve it?
Thanks !!!
Did you also try
Code:
fastboot flash boot boot.img
?
I can boot into twrp but every operation is causing the tablet to reboot

I didn't understand the problem, I think.
You flashed a patched boot.img and your twrp recovery isn't working? Like if you press a button, it just reboots?
I have fastboot BUT when I try to perform any command, it shutsdown and preety useless
Click to expand...
Click to collapse
If you do
Code:
fastboot devices
it also doesn't work?
Or only if you flash a img?

Phone booting normally, but unable to boots into recovery

Hi my k20 pro in working normally, means it boot like normally does, bootloaders are also unlocked, but when i trys to flash recovery via adb, it flashes normally, but when i try to boot into recovery it goes into fastboot mode, boot into recovery command also dosent work, i tried with latest twrp "twrp-3.5.2_9-0-raphael.img" and some old versions also.
tried flashing orange fox recovery also, but no luck, the only method via which i can boot into recovery is adb command "fastboot boot recovery.img"
Flashing recovery in TWRP when you fastboot booted twrp works or not?

Question fastbootD is gone

after playing around wiht treble/GSI images I just can boot into the bootloader. When I try to fastboot boot fastboot it boots into bootloader and not into fastbootD mode. I've tried to flash recovery.img, but it's still not working.
Has someone an idea?
Not personally but you should still have recovery which should get you back in business, just wipe.
It'll OOS back on board and you'll be good.
Without MSM I'd say use fastboot enhance, but I believe that requires fastbootd.
What if you just flash OOS system via fastboot.
You'll know you're there as you'll be able to type in fastboot devices and see your device.
yes, I've flashed some images (boot, recovery, xbl, modem) in normal fastboot mode, and finally it worked using fastboot enhance
