what's going on youtube geosmin right
0:01
here usually i get a lot of questions
0:04
about downgrades and the terms behind
0:06
those for example shsh blobs and sep
0:09
compatibility and stuff like that what
0:11
those are and what they mean and so on
0:12
so this is what we're going to clarify
0:14
in this video this video is brought to
0:15
you by phone rescue a program created by
0:18
imobi which allows you to recover data
0:20
from a device or from backups or even
0:22
from icloud backups if you have them but
0:24
it can also fix devices stuck in
0:26
recovery mode or apple screen or boot
0:28
loop and so on definitely check the
0:29
program out in the link below so many of
0:31
you know that you can actually upgrade
0:34
or downgrade to a newer or older version
0:36
in order to benefit from uncover or
0:38
taurine and so on and usually the
0:40
downgrade procedure is well documented
0:42
but it's usually pretty scattered across
0:44
the internet so i put together an
0:46
article here on my website called ios
0:48
downgrades blobs scp and baseband
0:51
explained for future restore in this
0:53
article i talked about basically all the
0:55
important terms what is sep when is
0:57
compatible when it's not what is
0:59
baseband why you need it and of course
1:01
shsh blobs how to use them when they can
1:04
work when they can't and so on i even
1:06
explained terms like nones non generator
1:08
tss server and so on so basically
1:10
everything related to downgrades i'm
1:12
gonna link it down below this article if
1:14
you want to check it out because it
1:16
contains a lot of important information
1:18
if you're planning to downgrade i'm also
1:19
currently maintaining here on my website
1:22
on the sepan basement chart over here
1:24
the future restore ios downgrade 7
1:26
basement compatibility chart and this
1:28
one tells you exactly what devices can
1:30
be downgraded and what devices cannot be
1:32
downgraded for example the sep and
1:34
basement for 15.4 would work for iphone
1:37
8 8 plus 7 seven plus and so on for
1:40
example for the iphone sc 2020 it would
1:42
also work sep and basement are
1:44
compatible you would be able to
1:45
downgrade with blobs saved with blob
1:48
saver or any other tool but for example
1:50
for the iphone 13 you wouldn't be able
1:52
to do that for iphone 12 it's completely
1:54
incompatible and the restore will likely
1:56
fail and i keep that for every ios
1:58
version i keep the historic data too
2:00
over here so that you know what is
2:02
compatible and what is not but the
2:04
article that i put together at the
2:06
beginning of the month this one about
2:08
sep basement and so on this one actually
2:09
explains everything what they are and
2:11
how they are used for downgrade purposes
2:13
one of the most important terms is the
2:15
sep or secure enclave processor i'm not
2:18
going to explain a lot in this video
2:19
because it would make the video too long
2:21
and there is already a huge explanation
2:23
over here on the website link will be
2:25
below so definitely check it out but sep
2:27
is basically the secure enclave
2:29
processor or a core in the chip on the
2:31
device that handles encryption and
2:33
passcodes and security and fingerprint
2:36
face id and so on and that one has its
2:38
own firmware and of course when you
2:40
downgrade you need to make sure that one
2:41
is compatible because when you downgrade
2:43
the restore procedure that you use
2:45
actually calls for you to get the sip in
2:48
the basement from the latest signed ios
2:50
version or at least one of the signed
2:52
ios versions and you have to make sure
2:53
that is compatible so i would definitely
2:55
recommend you if you're planning to
2:56
downgrade or upgrade to take a look at
2:58
this article first to see each term what
3:01
they mean and how they interact with
3:03
your restore because most of the future
3:05
restore failures are because people do
3:07
not understand those and how to check
3:08
the compatibility and so on and if you
3:10
do start a restore and it fails it could
3:13
render your device in a bootloop and you
3:15
may actually be forced to update to the
3:17
latest version available like 15.4.1 or
3:20
something and of course your jailbreak
3:21
chances go down a lot so to make sure
3:24
that you can actually downgrade before
3:26
you start definitely check out this
3:27
article i put together on my website and
3:30
definitely check out the compatibility
3:31
chart that i have on the website if your
3:33
device is listed here as not having a
3:35
compatible sep or base pen or it says
3:37
that it's technically compatible but it
3:39
will break face id do not attempt it if
3:41
it's green it's okay if it's red or
3:43
orange it will likely fail or it will
3:46
cause problems so it's best not to
3:48
attempt it downgrades with saved blobs
3:50
are possible but not always that's why
3:52
saving blobs is a good idea but not
3:54
necessarily a ticket to save you from
3:56
any screw-ups like updating to the
3:58
latest version so definitely check out
4:00
that article if you have any doubts
4:01
about downgrades how they work what the
4:04
terms like sep basement and so on mean i
4:06
have explained them in depth in that
4:08
article thank you for watching i am just
4:10
now till the next time subscribe to stay
4:11
updated and peace out
