Like installing the USB drivers, and SDK platform tools.
Then put the phone in fastboot mode and download an image from google and do a "flash-all.bat"

Hello, I'm posting this guide for those (like me) who can't do without TWRP on their device. I'm providing only a step-by-step explanation. Credits to @nikamura for his kernel and TWRP...

it wont work , that is what caused the issue, there is no adb or fasboot commands as the phone has nothing to load or read, it was flashing the official latest stock firmware using the flash-all.bat, then after the first rebbot and waiting for devices it goes to a black screen and shows what i put in the screen shot,(i believe the battery died during flashing) there is two modes it goes into the qusb which is the qualcomm download mode and some other mode i cant tell neither can the pc device find drivers to read the phone, techinically this phone is not fixable using normal methods , but i believe there is a way to flash to firmware back on,i have looked into using edl and qspt flashing but it still doesnt read the phone, any help would be greatful i have device protection but they are sending me a refurbished phone i would rather try to fix this before i do get the replacement, as it was a new and working deviceYou can try to go through the applicable steps in this guide:

files needed to repair phone, anyone able to extract or have files
RAM file (MPRGXXXX.mbn), e.g: MPRG8916.mbn
Boot file (XXXX_msimage.mbn), e.g: 8916_msimage.mbn
RAM file (MPRGXXXX.mbn), e.g: MPRG8916.mbn
Boot file (XXXX_msimage.mbn), e.g: 8916_msimage.mbn
I did the same thing as you trying to got back to stock. Still trying to find those files to unbrick myself.
I believe Qualcomm is the ones that obtain these files not Google , only other way is to dump the files from download mode on a working device
I'd like to help by dumping the required files, I didn't know anything about EDL before doing research for this thread, but as I understand using EDL mode require a device-specific non-free "loader".
I'm trying to use B. Kerler's EDL tool (https://github.com/bkerler/edl) but fail because it doesn't have the proper loader file in its database.
If anyone come across the loader for the Pixel 4a (000e60e10066000a_3ef72a02fb931be1_fhprg.bin), I'd be happy to share boot and memory dump from my phone.

Older thread I know, but I've used EDL mode (on LG phones) to save partitions and write partitions.
But you have to have a 'programmer file' for the specific device for it to work. Aka a 'firehose' file for the specific device / chip.
Some mfg's make this available, some don't. Google does not. So, even having the file(s) you want to flash won't help, not if you don't have the firehose file.
sorry, cheers

Only suggestions are the go to software of choice,, pixel flasher or android flash tool, both need bootloader unlocked
@hammered58 Gladly, I was able to get it back. I was trying to relock bootloader with custom ROM. But failed.

Right. Every apps working even on unlocked state. But would be nice to get rid of the warning while booting.
I will second that, unfortunately I don't think it's possible, at least not that IAM aware of
