Now I flashed the LGF500L tot using LG flash tool and updated my phone to nougat using LG Bridge. Now In about phone, the model has been changed from H815 to F500L
I want to unlock the bootloader and want to install the TWRP for custom ROM. The problem is I can't boot/reboot into bootloader/fastboot mode.
I have tried the hardware key combination and "adb reboot bootloader" but didn't get success, Every time the phone just restarts.
Is there any solution?
Also, the root permission has gone after updations.
So, in short I have 2 Questions/problems, please help me if you know any answer. I will be highly thankful to you

Thanks, @patilkalpesh for the screenshot.
F500L is written on my phone motherboard.
See attached image.
Currently, I am using F500L30b (nougat) version.
I can't boot into bootloader, the phone just restarts if I try to boot into bootloader (fastboot) mode. Please please solve this problem so that I can unlock the BL.

Can you tell me, why all USSD codes are not working?
for example: If I type *#06# then nothing happen or if I try any other ussd code then also nothing happen.
Is there any solution for it?

Yes dude being afraid makes totally sense and is for a good reason.
The risk is high, you can loose a lot or win a lot. Up to you..

Those codes are ROM dependent and you're using a brand new version (nougat for your device is just a few weeks old)
Maybe try
*#*#06#*#*
##06##

Can you check your anti rollback please? I don't know if the f500 has it implemented but that could be the reason.

thats very good (and so not the issue)
try to use an USB 2.0 port if u currently using a 3.0 one.. sounds still strange to me but I saw that error related to the usb port somewhere.
Besides that it could be likely a wrong msm DLL issue or you're just following the wrong guide.
I think this one should work for you too:
https://forum.xda-developers.com/g4/general/guide-lg-g4-stock-firmware-to-stock-kdz-t3107848
otherwise do a search on this error like here: https://forum.xda-developers.com/search/thread/3107848?query=0x2000
I would recommend better asking in the above thread for further help is better than going on in this thread here (has nothing to do with your original question btw... )

Locked phone with bootloop issue: is it possible to unlock bootloader?

Hi guys,
I have bought a used G4 with bootloop issue. It has locked bootloader.
Is it possible to unlock bootloader considering that this phone has bootloop issue?
Thanks in advance for the reply!

If you haven't already, you need to look in the 'guides' forum. There's a topic specifically to unlock the BL, and you'll also have to follow the info when you have a Verizon variant, which you have, because that's the one that doesn't have the OEM unlock in dev settings.
It's not that hard to do. Finding a workable TWRP is more involved. Not so much finding it but getting it installed. Because there is no recovery partition any more, twrp has to be ram-disk injected into the boot partition, that's where it gets more complicated.

Question OnePlus 11 Unlock bootloader/msm tool/custom rom

Hello brothers!
I'd like to know more about unlock bootloader, msm tool and about custom rom.
Does oneplus give us the ability to unlock the bootloader?
Is it possible to create a msm tool for it? I know that oneplus 10 pro had a problem with it...
As a oneplus 8/8 pro, 6T, op5, op3 and op1 user I always liked the fact that these were perfect phones for development. oneplus gives us such an opportunity at all now? My question is because I haven't seen it on op10pro...
I hope someone can answer these questions and we can talk about it together.
Best regards zelos156 aka zeusgod

No
There is fastboot enhanced which doesn't save you if you hard brick and can't get into fastboot flashing mode(not stock bootloader). Chinese users say there is a flash tool but nothing has surfaced yet. A dev who was trying to make it work for a cease and desist message from oppo

Oh that's stinks msm was a godsend for me because of the readback function built in to pull stock boot image for magisk

I bricked my OP11 and desperately need MSM : (
BL is locked, it stuck in a bootloop to recovery mode
PC can't detect the phone.
I couldn't get back to FASTBOOT with pressing physical key. Please help!

i had same issue, try disconnecting the cable then turn on while pressing all keys, somehow i got to fastboot,
am there at moment trying to figure out next

Thanks for sharing, I definitely need to try that! Did you press all keys and hold, or just press randomly?

So I can't get the drivers to recognize the device. OP does not have the 11 listed in the drivers download page. Are there other drivers that work?
**UPDATE** Disregard. Figured it out.

if you can access 9008 mode then you can recover It

Can you please tell how? My phone was stuck at EDL mode. I couldn't find any guide on how to recover and for some reason, QLMFlasherTrial was not opening in my PC. I have my phone to service centre for repair and still waiting.

Is there a link someone could share for unlocking bootloader or perhaps the payload dump method?

did you try to flash oos via edl or did you try to flash the firmware that was on the cell phone via edl? (if that is a china op11 you should flash coloros by edl with the tool if you have an AUTH. for the tool
