    No need to update ps3tools readself & readself2, it is still 0016 for 3.73 (same as 3.70/3.72) which afaik also means no new keys where added...
    Code:
    struct id2name_tbl t_sdk_type[] = {
    	{0, "Retail (Type 0)"},
    	{1, "Retail"},
    	{2, "Retail (Type 1)"},
    	{3, "Unknown SDK3"},
    	{4, "Retail >=3.40"},
    	{5, "Unknown SDK5"},
    	{6, "Unknown SDK6"},
    	{7, "Retail >=3.50"},
    	{8, "Unknown SDK8"},

    From Sony PlayStation 3 hacker Mathieulh via IRC on signing PS3 executables for 3.73+ Firmware:
    Code:
    [21:00:58]	<Mathieulh>	selfs are a mess to generate properly because a lot of values need to be calculated from the original elf file
    [21:01:11]	<Mathieulh>	the problem is right now all the public tools use hardcoded values
    [21:01:19]	<Mathieulh>	that are grabbed from various self files
    [21:01:21]	<Mathieulh>	but are not calculated
    [21:01:34]	<Mathieulh>	well that's one of the many problems actually
    [21:01:35]	<jevin> 	Mathieulh, things other than elf offsets?
    [21:01:40]	<Mathieulh>	yah
    [21:02:03]	<Mathieulh>	sony also did some fancy things with the compression self format
    [21:02:12]	<Mathieulh>	where values are off by a certain offset etc etc
    [21:02:38]	<Mathieulh>	if you want to make a proper self tool
    [21:02:44]	<Mathieulh>	you first need to reverse make_fself
    [21:03:06]	<jevin> 	not too hard with hexrays *cough*
    [21:03:09]	<Mathieulh>	that's the initial step
    [21:03:15]	<Mathieulh>	yeah it's not that hard
    [21:03:29]	<Mathieulh>	then you'll figure what a big fck up the self format really is :D
    [21:05:14]	<Mathieulh>	but yeah just my self.cpp is 5 times larger than the entire source for geohot make_self/make_self_npdrm
    [21:05:27]	<Mathieulh>	in terms of lines of code
    [21:05:48]	<Mathieulh>	so his is missing shitloads of stuffs and only relies on hardcoded values
    [21:06:06]	<jevin>	        entire headers copypasta'ed from existing selfs
    [21:06:11]	<Mathieulh>	pretty much yah :D
    [21:06:23]	<Mathieulh>	the ones on the tool I use are generated
    [21:06:32]	<Mathieulh>	as in calculated and generated
    [21:06:36]	<Mathieulh>	from the original elf
    [21:06:52]	<Mathieulh>	btw unself is buggy too
    [21:06:54]	<Mathieulh>	just so you know
    [21:07:16]	<jevin>	        why haven't you labeled the control flags? :)
    [21:08:16]	<Mathieulh>	jevin I didn't feel the need to, I already know what they do anyway
    [21:08:37]	<Mathieulh>	for example 0x40 is root rights, 0x20 is debugger rights and so on
    [21:09:07]	<jevin>	        i'm guessing the self capabilities flags are offset 0x20 in the self header
    [21:09:18]	<Mathieulh>	capabilities aren't in the header
    [21:09:23]	<Mathieulh>	they are part of the metadata
    [21:09:28]	<Mathieulh>	as in, they are encrypted and signed
    [21:10:16]	<jevin>	        offset 0x10 in the section header?
    [21:10:29]	<Mathieulh>	it's after the metadata keys
    [21:10:33]	<jevin>	        no, they wouldn't be per section
    [21:10:50]	<Mathieulh>	as in, right after them
    [21:11:09]	<jevin>	        i see. so unself doesn't have enough fields in the metadata header
    [21:11:35]	<jevin>	        i really should color in the hex values that are mapped to structures in unself vs ones that arent
    [21:11:42]	<jevin>	        seems like it is missing a lot
    [21:11:49]	<Mathieulh>	everything public is missing tons
    [21:12:15]	<Mathieulh>	capabilities are optional mind you
    [21:12:35]	<jevin>	        are they restrictive or permissive?
    [21:13:11]	<Mathieulh>	restrictive
    [21:13:16]	<Mathieulh>	(for most)
    [21:42:15]	<jevin>	        Mathieulh, you said that the geohot npdrm keypair is blacklisted in 3.56
    [21:42:30]	<jevin>	        i couldnt find the decrypted or encrypted metadata keypair in 3.56 files
    [21:42:47]	<jevin>	        where does the blacklisting occur? is it a hash that is blacklisted?
    [21:43:08]	<jevin> 	its interesting to me because we can make our own keypairs now with juan nadie's work
    [21:48:45]	<Mathieulh>	<jevin> Mathieulh, you said that the geohot npdrm keypair is blacklisted in 3.56 <== not only that
    [21:49:03]	<Mathieulh>	geohot stuff doesn't generate some of the npdrm specific values
    [21:49:08]	<Mathieulh>	those were not checked in 3.55
    [21:49:13]	<Mathieulh>	but they are checked in 3.56 now
    [21:49:55]	<jevin>	        Mathieulh, gotcha
    [21:50:09]	<jevin>	        is his keypair actually blacklisted somewhere though?
    [21:50:10]	<Mathieulh>	there is no whitelist for npdrm
    [21:50:22]	<Mathieulh>	so it's actually possible to generate valid npdrm self for 3.56+
    [21:50:42]	<jevin>	        is it a check in appldr?
    [21:50:43]	<Mathieulh>	that tool I made a screenshot of actually does that
    [21:51:02]	<Mathieulh>	jevin yeah, it's enforced by lv1 though
    [21:51:16]	<jevin>	        a hash comparison?
    [21:51:27]	<Mathieulh>	yeah it's a hash
    [21:51:30]	<Mathieulh>	but I won't say more
    [21:51:35]	<jevin>	        ok :)
    [21:51:55]	<Mathieulh>	everything you need is in the 3.56 fw :p
    [21:52:16]	<jevin>	        rgr, i will poke around later
    [21:52:34]	<jevin>	        the checks are unmodified in 3.60+?
    [21:52:43]	<jevin>	        + new keys of course
    [21:52:51]	<Mathieulh>	same checks
    [21:54:53]	<Mathieulh>	jevin you won't get around crafting valid 3.56+ npdrm selfs without a proper makeself tool though
    [21:57:18]	<jevin>	        would SCE make npdrm selfs work if actually signed?
    [21:57:25]	<jevin>	        + crypted
    As always, more details will be posted below as they are available on the update should any hidden features surface.

    They are trying to cover another exploit as GrandpaHomer pointed out to the point that it is just downright pathetic and pitiful.

    That, plus it's getting annoying to many I'm sure to keep downloading updates that don't bring any new features.

    Seeing as its not mandatory that would suggest that its not security related, and as they say for stability.
