This trick will allow you to install your favourite Homebrews as bubbles to launch directly from the live area. No need for VHBL or eCFW at all.
This method works for EVERY Vita Firmware as of now!
Note: To install a 'fake-signed' PBOOT.PBP file on Firmware 3.50 - 3.52 you can either use the mail writing trick or swap the memory card with an older Firmware Vita. For 3.36 and below you can just use any eCFW with I/O patches or the mail writer of course.
If you however are on 3.55, you would need to buy an exploit game and use qwikrazor's pboot installer (see the ARK / TN-V tab for more details and files), or alternatively apply the PBOOT.PBP manually via VHBL or another lower firmware vita!
And if you happen to run any higher firmware, like 3.57 for example, you can still use the created bubbles but are out of luck to create them on your firmware!
Best way of installing for different firmwares:
up to 3.36 - Use any eCFW or the FailMail trick to write a PBOOT.PBP to any game.
3.50 to 3.52 - Use the FailMail trick to write a PBOOT.PBP to any game.
3.55 - You need an exploit game to install the PBOOT.PBP
3.57 - You can't create any new bubbles for now (but still use formerly created ones)
3.60 - You can use HENkaku to write the custom PBOOTs directly to ux0:pspemu/
3.61 to 3.63 - You can use the backup editing via PSVIMGtools
