When it comes to stepping into custom development, then a custom recovery is the best tool that you could have in your arsenal. From the ability to flash and sideload ZIP files to take a backup of all the partitions on your device, it beholds a slew of useful functionalities. However, in some instances, flashing it could prove to be quite a tough nut to crack.
If a device does have a recovery partition, then you could directly flash it to that partition. However, nowadays, many devices don’t have a dedicated recovery partition and hence you’ll have to take the help of the boot partition to get the job done. Likewise, if you are just looking to boot your device to TWRP for one-time usage, then also you’ll have to take the help of the boot command instead of flash. In both these cases, the command will be fastboot boot twrp.img. However, some users are reportedly getting an error while trying to do so, something along the lines of:
fastboot boot twrp.img
