Hi Everyone
Due to the number of post's I've seen asking how to install a patch, using this program, I decided to do a tutorial with pictures, hopefully making it quite easy to understand .... Here we go ...
MAKE A BACKUP of your GDFS before making ANY changes to your computer ...
I am not held responsible for any damage to anyones cell phones.
How do I backup my GDFS?
A: The cell phone was identified, this gives you the option to READ GDFS
so setool's create's a backup of your GDFS (in the folder where isetools is installed)
I recommend: update the flash drivers with those that come in the new setools 2 lite 1.11 version.
GETTING STARTED: First of all you must download Setools 2 Lite 1.10 and upgrade to version 1.11
(do not put pictures of this because it is far from basic, ongoing)
then you create a patch (quick patch) which will not corrupt our main, and so the patch as quickly DB2010 CID49 ...
I feel like this patch? simple: copies of the MAIN FIRMWARE which are using, in my case K790_R6BC002_MAIN_GENERIC_EV_RED52.mbn to qamaker this folder inside the folder and drag setools2lite the application qamaker.exe as this picture shows:

after that you gonna window:

There will be creating a patch for fast access "quick access"

taking the patch for fast access and our main, proceed to patch our team DB2020; the main charge of our team in FILES, and the patch that we created in MISC FILES, the option labeled "Bypass DB2020 Security" and give it to FLASH. (omit the step of IDENTIFY that it is already CID, FIRMWARE, so are my SE.)

We wonder if deceamos remove "YES" or add "NO" the patch
(obviously get a puncture "NO").

Delayed about 15 minutes the process, I recommend that you let the program work quiet ...
Now we are going to generate our patch UNLOCK
Donwload:
4shared.com - online file sharing and storage - download SIMLockPatchGen_v2[1].1.rar
The load Main, then prick "make patch" and vualá, our patch release UP!

Now comes the entrete and fast, faster patch with setools ....
as we apply the patch for fast access to our team can use the option before dimension "use quick access patch"
then, the options labeled "bypass DB2020 security" and "use quick access patch" saddle our patch generated by the program simox and get a puncture in MISC FILES 'WRITE SCRIPT "

We will leave the confirmation window again:

good to know that should click on "NO" to apply ....
we hope it finishes and READY .. our DB2020 UNLOCKED!
NOTE: You can apply any patch in the same way, obviously the passage of the patch of quick access, is "ONCE" This is not to corrupt the MAIN every time you patch ....
if you served not hesitate to press THANKS
greetings!
