PostSubject: XTC-CLIP version 4.0.1 released   11/3/2013, 10:08 am

XTC-CLIP version 4.0.1 released

What's new:

1. HTC LEGEND HBOOT-0.43.X001 added to supported devices

Note:
Just update your clip from software interface menu !!

What is S-OFF?

after doing your phone S-OFF, you do set follow functions on factory settings

- sim lock
- hboot lock ( this is the bootloader lock, you will be able flash cooked rom after this)
- cid lock (region lock so you can't flash it with other roms, unbrand it, or downgrade it)
- user lock (will be set to factory default)
- pattern lock (will be set to factory default)
- phone usage counter (helps you refurbish the phone)


Temproot and Permaroot
- What's the difference?
First, let me explain root access. Root access, superuser or su (all the
same thing) is basically an admin account for Linux. It gives us
permission to to access commands that normally couldn't be accessed, and
to write information to partitions that normally couldn't be written
to. On older devices (such as the Hero), once we had root we could write
to the /system and /recovery partitions, and flash custom ROMs. In the
case of the IS (and every HTC device since the desire), this isn't true.
Getting root access is quite trivial and no where near as useful,
because the internal flash memory (NAND or eMMC) is locked down and it
means we everything we 'write' to the system (or any other protected
partition) is lost on reboot because it is a non permanent change. In
short, this stops us from flashing custom ROMs and recovery. This is a
problem for any devices that are shipped with the Security flag on
(S-ON). To get Permaroot, and the ability to flash custom ROMs, we need
S-OFF.

So what's this S-OFF then?
Making the phone S-OFF with XTC clip, means also that you reset the
simlock, userlock and CID to factory state !!! Mean, your phone is100%
UNLOCKED
Since the Desire, HTC have been securing their phones better than before
by locking the internal flash memory (NAND or eMMC) to stop it being
written to, unless the file being flashed is signed by a private key
only known to HTC. This is controlled by a flag (@secuflag) and is
identified as the device being S-ON. Telling the HBoot the device is
Security Off (S-OFF) stops this check for the key, and allows us to
write anything to any partition, which is what we are aiming for.

There are actually two levels of S-OFF. The Bootloader (HBoot) and the
Radio. Getting S-Off on the HBoot gives us everything we need, but
doesn't actually turn off the @secuflag which is set in the radio. What
it is possible to do is to flash a HBoot that believes the Radio is set
to S-OFF, as the HBoot is responsible for setting that flag. Once the
HBoot on the phone is S-OFF, we can write to all the partitions and
basically do whatever we want, but it is possible to go one step
further. Flashing a radio that is S-OFF and actually setting the
@secuflag off gives 100% total access to every part of the phone and
it's software, as it becomes network unlocked allowing to you to use any
SIM and also allows you to flash a ROM from any carrier (known as Super
CID). It also makes it nigh on impossible to permanently loose root no
matter what you flash. Once you have radio S-OFF, it makes it much
easier to flash new HBoots and ROMs even if you flash something that is
locked down tight.
Setting the Radio to S-Off is not necessary, and gaining S-OFF on the
HBoot is more than most people will ever need. Radio S-Off is just the
last step of the puzzle, but it is worth noting the only points you can
permanently brick your phone is flashing a radio or a HBoot, if either
of these go wrong you will end up with a shiny expensive paper weight so
there is risk involved.

What about this XTC Clip, can that help?
The XTC clip is a hardware device that can unlock S-OFF HTC phones, regardless of the software.

S-OFF created by XTC Clip is temporary or permanent?
You can flash your phone as many times you want, your HTC will remain
S-OFF forever, it is a permanent S-OFF !!!
What about people who are getting devices shipped with S-OFF? There are
reports that a lot of devices coming out of China and India are shipping
with the @secuflag set off. These are lucky people, and have the
ability to write to the flash memory, but it can't help those of us who
are S-ON. It is also worth noting that because most devices are S-ON, no
one has written any ROMs or kernels for the device so they will
probably have to wait until we get a way of turning our devices to S-OFF
until anyone creates any software for it.

Bootloader a.k.a HBoot
- This is the piece of software that runs before anything else on the
phone. It basically packages it all up, tells what to run in what order
e.t.c Every computer device has a bootloader in some form or another, be
it an Android Phone, iPhone, Windows PC, iMac e.t.c. The HBoot is
accessible by switching your phone off, then holding down volume down as
you turn it back on. The first line of the HBoot will tell you if you
are S-OFF or S-ON.

Recovery
- The recovery is the piece of software that allows us to write files to
partitions while they aren't being used. It is the portal to allow us
to flash custom ROM's and kernels. There are custom recoveries with more
options than the stock such as ClockworkMod.

Superuser a.k.a su or Root
- This is a user that is present on all linux distros that allows higher
permissions than standard users have access to. Certain apps need
superuser permissions to function, such as Titanium Backup.
