DSLL-MDR72: PS Vita / PS TV 3.71 & 3.72 Downgrader to 3.65 Firmware by SKGleba

Following the H-Encore2 PS Vita 3.65-3.71 Jailbreak and Sony's 3.72 OFW Update comes a PS Vita / PS TV 3.71 & 3.72 Downgrader to 3.65 Firmware by SKGleba on Twitter, with a dsll-mdr72.vpk guide below alongside a video tutorial from NanospeedGamer on his YouTube Channel.

Download: dsll-mdr72.vpk / GIT / modoru.vpk (no need for dsll-mdr72 any longer) / GIT

As always, downgrading is done at your own risk so be sure to follow all documentation closely to avoid the possibility of PlayStation Vita / TV bricking!

From the README.md: Plaintext update_sm loader for 3.71 - 3.72 based on decsec-ldr

This tool will make lv0 load plaintext "ux0:data/update_sm.bin" instead of "os0:sm/update_sm.self".

Usage

1. Download and install the VPK
2. Put decrypted update_sm elf in "ux0:data/update_sm.bin"
3. Run the app, it should say "module loaded"
   • If it hangs or crashes you will need to reboot by holding the POWER button

Notes

• Framework injection reliability: 25%
• Framework stability: 90%
• Before performing dangerous operations such as downgrading please make sure that the framework is stable (i.e by running the settings and welcome park apps)

And here's the Vita/TV 3.72 downgrade guide from Pastebin.com:

How to downgrade PlayStation Vita and PlayStation TV from firmware 3.71 or 3.72 to firmware 3.65.

1) Required files:

• PlayStation Vita firmware 3.65: PSVita OFW 3.65 complete.zip (the "full" pup - 302.20 MB)
• PlayStation Vita firmware 3.72: PSVita OFW 3.72 complete.zip (the "full" pup - 302.3 MB)
• Latest release of modoru by TheFlow: modoru.vpk
• dsll-mdr72.vpk by SKGleba: dsll-mdr72.vpk
• Decrypted 3.65 update_sm: update_sm.bin (39 KB)

2) Preparing everything

• Install both VPKs via vitashell
• Copy the 3.65 PUP to ux0:app/MODORU000/PSP2UPDAT.PUP and the 3.72 PUP to ux0:data/PSP2/UPDATE/PSP2UPDAT.PUP if you have a memory card
• Copy the update_sm.bin to ux0:data/update_sm.bin
• Power off your device

3) Downgrading

• Power on your device
• Enable homebrew with h-encore2
• Start "decsecldr[LITE]", wait until it says "module loaded" and then press [start] to exit
• If your console hangs (longer than 15secs) or crashes - hold the [power] button for 20s and repeat from step 3, this may happen A LOT of times, good luck!
• Start "modoru" and follow the instructions displayed on screen
• That's it!

4) Troubleshooting

• If you get a long "floating bubble" before modoru starts - abort the process and repeat from step 3.
• If you encounter a crash during the downgrade process (green screen) - reboot to safemode by holding PS+RT+POWER and select update system firmware->update from vita memory card.

Trying to downgrade my 3.72 PSTV and I keep getting Green Screen error so I went into safe mode like troubleshooting said and selected update via memory card. But it just installed 3.72 again.

Finally got it done after 3 failed attempts. Turns out it was Modoru 2.1 didn't work for me. Cuz switched it to 1.0 and worked np on 1st try.
