PS4 Jailbreaking       Thread starter PSXHAX       Start date Dec 12, 2016 at 4:47 AM       31,112       36      
We covered the PS4 HENkaku Exploit Port awhile back, but the topic is still quite active on Spanish site Elotrolado.net where a work-in-progress (WIP) version of a UniversalFlash App to dump / read the internal PS4 Flash Memory (aka Sysconf, where updates are installed) was just released by HybridComputers that utilizes a Teensy board (remember a Teensy++ v2.0 can be used to downgrade PS3 consoles) to potentially downgrade and execute PlayStation 4 apps without a license required... with an indirect Kickstarter coming in the next few days. :extremelyhappy:

Previously we reported on the PS4 NOR Chip Dumping Process, a PS4 Flash Dumping / Unlocking Method, the PS4 1.76 Flash Dump Analysis and a PS4 SFlash Guide... could any of these techniques be used in the Egyption PS4 Jailbreak Method that recently surfaced if it's not just another gamesharing trick? :nocomment:

:arrow: Update: A better translated explanation of what's being discussed below can now be found HERE by @Crish who is KirtashTheShek (below) on ELO.

Anyhoo from HybridComputers, to quote roughly translated: "Dedicated hosting ... high price ... but we have already found a way to finance those who have teens and try this program, with the permission of universal team .. you buy this universal flash in the attachment.

The mythical "Calimba" I do not know if you remember a scener right here from Hades Team :-D... that gave beginning to the ode of ps3 is in that equipment... and besides that in PS4 Pro at the end there are datasheet of sysconf, .. which serves for a possible downgrade of consoles Super Slim... not Pro.

The Pro only up to 3.70 or model that comes from factory .. something that is worth gold if you can say... stay tuned to kickstarter is going to come out something that has to do with all this indirectly.

Ubuntu UniversalFlash v.01 some Universal functions available as Wii U... dump XBOne, 3DS.. PS Vita only available in the second version v.02... I was only allowed to publish this version v.01.. probably with Teensy.. this version is v1.0 in the second version is working on something that does not add padlocks since it supports for the sysconf to detect the exact consecutive and not generate padlocks in what we will call the apps.

Please do not talk about backups... use it for whatever you want. :beer::beer:"

Also from KirtashTheShek to quote, roughly translated: "Nothing is safe (For now) this program only serves to read the internal flash memory of the console (called Sysconf, which is where the updates are installed) then only time will tell... Salu2!"

:stop: Some other related points of interest for what they're worth, according to CVE logs via @SorenAlke the PS4 Pro 0Day Exploit is nothing more than a 'file dropper over metasploit' and @Chaos Kid notes it was patched, perhaps in the recent PS4 4.07 OFW update although it still won't protect current stock PS4 Pro v3.70 consoles from the vulnerability. :happyblush
Above are some videos from Andrew Paul on PS4 Controller Sync NOR Flash Corruption Repair and Building a Teensy Programmer, and thanks to @Crish, @Fimo, @TheOneAngel in the forum HERE, @VultraAID and @yourfakers in the PSXHAX Shoutbox for the scoop and translation assistance. <3

Do you think its wise to update it? You might lose the jailbreak. I don't know if 4.05 is possible since I know 3.50 to 4.05 is exploitable but I don't think 4.05 is possible unless I am wrong.

EDIT: We can't play Ratchet and Clank on PS4 since it require 3.15 to be playable but our PS4 is 2.57 but I refused to update it at all. We are patient. It will be worth.

well as far I know from this site and other forums as well, it was patche in 4.06 so I think 4.05 is safe to update to...

Any one know how to Use JTAG port in MEDIANAV EVO 7.0.5 CAR STEREO. What tool is used to Flash the NOR CHIP "MX29LV320ETTI-70G 32Mbit MACRONIX".

The bootloader is corrupted. I have a bootloader file "boot_loader.bin" and also have firmware filw "upgrade.lgu".

Since the medianav device doesn't boot and is struck at logo and not getting into WinCE with the help of NK.bin file and also by reseting the processor using Resister R1021 with gnd signal. I am forced to use JTAG port for updating the boatloader and firmware from JTAG port.
