Hello mate ,
Does your phone gets directly stuck on oppo logo as soon as power on the device or the boot animation is carried out and then it’s stuck on the logo ?
Btw you can start from safer procedure , firstly try to hard reset (try oppo reset and choose format data ,don’t save data).
Secondly you can try flashing stock rom but mate there’s a catch don’t try to flash it via write by via ISP connection mode as it will disconnect regularly over time yielding a error and finally your flashing will be interrupted and your phone will be gone . You need to take the chip off for flashing this device , or you need to find a good healthy ROM1 back up over 8gb in size with all partition backups like system , vendor etc to flash via isp , which is kinda hard to find .
Please Make back up of your security partitions before proceeding with any operation .
Best Regards .
