[OnePlus 7 Pro Guides, News, & Discussion] mauronofrio:
Things are changing with the advent of project treble and seamless updates. OnePlus will no longer release ROMs flashable via stock recovery because is no more needed. The updates will be done on the slot not used for example if you are using slot a the update will be installed on slot b and the slot b will be set as default. If you brick and you are in bootloop how you can restore the rom? You can't with Stock ROM you have, because the zip can be only installed via Update Engine, so what can you do? Flash a stock rom via fastboot. I have extracted all images from the stock zip and i have made a new zip with the Fastboot ROM with a flash-all.bat included. This will work only if your bootloader is unlocked. This will erase all your data and will wipe your internal storage.

HOW TO FLASH

This version is only for not branded devices

Download the zip;

Unpack the zip in a folder;

Reboot the OnePlus 7 Pro in fastboot mode (Power and volume + and volume-);

Connect the OnePlus 7 Pro to PC;

Run flash-all.bat flasher you need;

Wait until the process end;

The phone will automatically reboot.

FLASHER ADVANCED GUIDE

flash-all-partitions-fastboot.bat : this .bat will flash all possible partitions through fastboot (Except persist) , there are some criticals partitions that can't be flashed through fastboot;

flash-only-persist.bat : this .bat will flash only persist partition in fastboot mode (This is good for people that have problems with sensor);

flash-all-partitions-recovery-criticals.bat : this .bat will boot the twrp and will flash criticals partitions, use this carefully;

flash-system-boot-vendor.bat : this .bat is the same of older flash-all.bat and so it will flash only vendor, system and boot;

flash-all-partitions.bat : this .bat will run flash-all-partitions-fastboot.bat , then flash-only-persist.bat and then flash-all-partitions-recovery-criticals.bat .

Now usually the one needed is only the first "flash-all-partitions-fastboot.bat" but if you are badly bricked i recommend to use flash-all-partitions.bat .

REMEMBER

"Invalid sparce file format at header magic" is not an error, you need to wait a bit when you see that string, just wait.

These ROMs can't be used to update or downgrade your phone but just to restore your phone, so don't use them to come back to oreo or to update from oreo to pie.

If the rom seems doesn't start go in recovery stock and follow this guideline: English -> Wipe data and cache -> Erase everything.

If you want to rebrand your phone from HydrogenOS to OxygenOS you can follow this guide: Rebrand Guide

If you want you can use also my tool to flash Factory Images, unlock bootloader, flash twrp or to understand if the device is recognized: https://toolaio.tk/
