can't see (blackscreen) ONLY in fastboot mode

[vesp9]

i want to move to lineageos from the custom rom, but i have this problem, tried to google solutions in different ways but i can't find people with the same issue.

phone works fine otherwise, but when i have it completetly OFF and try to start it by holding power+voldown keys i go into fastboot (i can tell cuz if i dont touch it it stays on a black screen with lil to no light). and as soon as i press the power key (effectively choosing to do a reboot), it powers off and on and goes on to boot my old config.

btw i have enabled OEM and usb debugging. but i haven't got root access cuz it's my understanding that to get that i need to do some things to it in fastboot hooked up to a pc with ADB minimal.

any ideas?

hello there! I have the exactly same issue here.. Volume DOWN + Power goes to black screen....
However i could find out that it is, indeed entering in the fastboot as i was able to send commands and unlock the bootloader through the CMD.. But now i cannot get to install the TWRP (get some error). Did you solved it? anyone can help?

i just figured it out, what commands are u using to install twrp?

well, for anyone in the future wondering about this **** u gotta make sure the usb port in your pc is 2.0, a 3.0 will return failed access to the unlock data or the flash boot command for twrp

and u gotta use >fastboot flash boot ''twrp file name''.img

also, for this specific model evert or moto g6 plus if u using the lineage official release make sure the number after the mindthegapps file matches your version of android, i ****ed that up many times until i realized i was trying to install MTG 10 in android 13. what a ****head am i!

oh, and finally if u are in fastboot and can't see anything, the path to recovery (and hopefully twrp) is to press 2 times voldown and 1 time power

Also, in other topic they pointed out that some Moto G6 Plus have only ONE partition, so you cannot FLASH a recovery (because they dont have a partition for that).. you can ONLY boot on TWRP, if you Flash the TWRP on the partition you cant have a OS at same time..

Tried to do that, but stills black screen after 2 volume down plus power

u want to enter twrp? make sure a copy of the file its on sd and do ''fastboot devices'' first to make sure connection is ok. then ''fastboot boot (twrp.img)''

changing twrp.img to the exact name of your file. on usb 2.0 or it won't work

I have the same issue.
After it boots into TWRP, the screen correctly display TWRP or is still black?

it correctly displays TWRP, it's black just in fastboot.

u can use adb while in fastboot to order it to boot twrp, that's how i did it. or i guess u could hypothetically make it go into recovery mode (twrp if installed) by moving blindly using vol + or - but i'm not sure.

Oh that's a relief! I was planing unlock the bootloader and flash LineageOS this weekend. I will report back how it goes.

remember to use usb 2.0 (not 3.0). this made me waste so much time

Indeed, I struggle with that on my G7 Plus, cheers!

Update; After successfully unlocking the bootloader, I boot to the Pixel Experience recovery and the screen remains black.
But if I boot to TWRP, it does display it correctly.

i'm guessing the pixel experience recovery is a custom recovery mode, right? maybe the black screen it's a thing with factory menus? idk

Yes, is just like the LineageOS recovery.
I always replace the Rom's recovery with TWRP in any case.
