Introduction

What until couple of days ago, was just a rumor, has become reality, once again, thanks to Dark_AleX, Harleyg, and Mathieulh. This allows us to have 2.71 firmware, with the 1.50 firmware functions. Yes, you not seeing things. It seems that 1.50 firmware no longer have a future.


Precautions

Precautions
//The flashing is a delicate process, since we are going to format the flash memory(flash0) of the PSP and install a "new firmware", so make sure you battery is fully charged, and the AC adapter is connected to the PSP.

//This guide will assume you have a 1.50 PSP. If you have 2.71 SE-A, read the FAQ below to learn how to uninstall it. If you have any other firmware, downgrade to 1.50

// DO IT AT YOUR OWN RISK!, Neither BlackSkull for making this tutorial, Dark_Alex, Harleyg, and Mathieulh for creating this Custom Firmware or any other person will take responsibility for any failure resulting into a brick.

Installing the Files

Rename the 2.71 Update Eboot to 271.PBP and copy it to the seupmaker folder.

//When asked, overwrite the PSP and the GAME folders.

Now, In the PSP, Go to GAMES > Memory Stick and start the SE UpdateMaker.

Once it finish (takes about 3 or so minutes), It will return to the XMB, Connect the PSP to the USB port, and now a new file in PSP/GAME/SEUPDATEMAKER, named DATA.DXAR, should be there. The update maker no checks the DATA.DXAR, so there is no reason to check it yourself. Copy the file DATA.DXAR to the directory "PSP/GAME/271SEFLASHER".
