hello all, I got it at the end we have a downgrader for slim consoles this time is different than it has done with consoles fat, I’ve got the two flashers progskeet Teensy + + and Al nougat!

We need:

fat or slim console with updated standards to 3.70 “DO NOT TRY TO ANOTHER VERSION”
Solution to write and read the rules of the console (or flasher progskeet teensy + +)
hxd program (which I use to edit hex)
FlowRebuilder v.4.1.3.2
a beer (this is important)
You must login or register to view this content. Downgrade.bin

First dumped our NOR flash, the file must accurately measure “16,777,216 bytes” neither more nor less Draw out several to be absolutely sure of what you do

cojemos the dump “example josejuan.bin”

and we have to introduce it in a file flowrebuilder to make it readable (bytereverse) the option is called bytereverse dump and extract rules

what we do and we will create a file but the extension ends in. bin.REV

open it with the hxd and took our personal data to the console EID, BOOTLOADER, CSID and METLDR no need to put any more

take them out as follows:
choose for example in this case to stick our METLDR prepatched to downgrade the image attached to this tutorial

inside the folder where we put the flowrebuilder. rev also has created another folder called “nombredeldump.EXT”
then there are our personal archives of our console and we need to introduce them to catch some pre-patched image that I have since opened the hxd and open the file and metldr downgrade.bin is inside the folder asecure_loader
choose the tab on the hxd metldr and copy the entire contents into HEX and enter the downgrade.bin
press control + 820 g write position is that of METLDR
right-click on the first line of position 820 to give to “stick type” and so the same way we introduce others to enter the files are:
METLDR: Position “820″ size “EDE0″
BOOTLOADER_0 Position “FC0000″ size “40000″
EI Position “2F000″ size “10000″
CIS Position “3F000″ size “800″

then we take the downgrade.bin with saved changes and we put in the option flowrebuilder bytereverse dump and extract rules PROGRAM THIS TIME WE WILL GIVE AN ERROR but is a normal error, if error occurs is that okay done and you create a file named downgrade.bin.REV will be the file you have to enter in the console “flash”

if all went well to finish writing you kindle the console and will press the button or English ps ps push button NO NOTHING PULSEIS apagais the console and put it in factory service mode once this need to put the correct file system for 3.55 jaicrab with lv2diag of cfw without reader and a special

kindle the console with the stick with these two files on the usb device into the far right of the console and shut down one to 10 / 15 minutes, kindle the console without any usb connected to verify that you correctly leads to xmb If all went well apagais the console and you put your lv2diag FILE2 of this pack:
