Hello! I'm a newbie who bricked his Blackview BV 6300 Pro (EEA). I was trying to backup my NVRAM following the procedure described on the ROM-PROVIDER website (How To backup NVRAM on Mediatek MT67XX Devices - ROM-Provider (romprovider.com), but something went wrong. Now the phone does not start. I wanted to flash the ROM downloaded from the same website to repair the phone, but I get the following message: "The Preloader file format is invalid! (HINT): Please retry another official load". I need your help, please!

U got that error and your device was unable to boot because u did not input a valid preloader.bin why backing up using spflashtool.

Use the one with codenames and Russia ,and also the the preloader.bin that doesn't have disks ? sign should also be use ,hense is same with the one with Russia

To use preloader when u load the created empty scatter file by wwr ,u will have a partition along name preloader just double click on its location and navigate to where u have that preloader.bin and load .by doing so u can be able to read back, without the initial error
