[Q] How in the world do I program this thing correctly? :(

[Q] How in the world do I program this thing correctly? :( - General Questions and Answers

So I've been teaching myself C++ for the past two days (this is my first language), and I've pretty much come across a brick wall. The book I'm studying with is asking me to create a program where the computer guesses YOUR number. So pretty much I tried to create a high/low game where after every guess, the upper and lower limits of the range would become more and more narrowed down, eventually leading to increased probabilities of the computer guessing the number I'm thinking. I think I've gotten most of the code down... but it's just not working! I've tried my Google-fu, but none of the answers I've seen seem to approach it the same way I am. Any help?
// Guessing game
// The computer tries to guess a number input by a person.
#include <iostream>
#include <cstdlib>
#include <ctime>
using namespace std;
int main()
{
srand(time(0));
char confirm;
cout << "Think of a number from 1 to 50." << endl;
cout << "Are you ready? (y/n): ";
cin >> confirm;
while (confirm == 'n')
{
cout << "Please take your time." << endl;
cout << "Are you ready? (y/n): ";
cin >> confirm;
}
int randomNum = ( rand() % 50 ) + 1;
int currentGuess = randomNum;
char correct = 'n';
char highlow;
int lowerLim = 0, upperLim = 51;
int tries = 0;
cout << "Is your number " << currentGuess << "? (y/n): ";
cin >> correct;
++tries;
while (correct == 'n')
{
cout << "Is it higher (h) or lower (l)?: ";
cin >> highlow;
if (highlow == 'h')
{
lowerLim = currentGuess;
while ( true )
{
currentGuess = ( 50 - ( randomNum % lowerLim + 1 ) );
if ( currentGuess < upperLim && currentGuess > lowerLim )
break;
}
}
if (highlow == 'l')
{
upperLim = currentGuess;
while ( true )
{
currentGuess = ( randomNum % upperLim + 1 );
if ( currentGuess < upperLim && currentGuess > lowerLim )
break;
}
}
cout << "Is your number " << currentGuess << "? (y/n): ";
cin >> correct;
++tries;
}
if ( tries == 1 )
{
cout << "Yay! I got it on the first try!" << endl;
}
else
{
cout << "I got it in " << tries << " tries!" << endl;
}
system("PAUSE");
return 0;
}
edit: So I've kept working on it, but for some reason, it just stops after a few guesses. But at least now it's staying within the range defined by previous guesses....
This is driving me nuts, please help me.

I did something like this in java, and the problem is the way you generate the random number. Change that and it will work. This link should help. http://stackoverflow.com/questions/363681/java-generating-random-number-in-a-range

Android 4.2 Change Default orientation to Portret

Hi!
I`m porting Android 4.2.2 to my Device, and have a problem with screen default orientation!
Code:
public DisplayDeviceInfo getDisplayDeviceInfoLocked()
{
String str;
if (this.mInfo == null)
{
this.mInfo = new DisplayDeviceInfo();
this.mInfo.width = this.mPhys.width;
this.mInfo.height = this.mPhys.height;
this.mInfo.refreshRate = this.mPhys.refreshRate;
if (this.mPhys.secure)
this.mInfo.flags = 12;
if (this.mBuiltInDisplayId != 0)
break label264;
str = SystemProperties.get("ro.sf.hwrotation");
this.mInfo.name = LocalDisplayAdapter.this.getContext().getResources().getString(17040667);
DisplayDeviceInfo localDisplayDeviceInfo = this.mInfo;
localDisplayDeviceInfo.flags = (0x3 | localDisplayDeviceInfo.flags);
this.mInfo.type = 1;
this.mInfo.densityDpi = (int)(0.5F + 160.0F * this.mPhys.density);
this.mInfo.xDpi = this.mPhys.xDpi;
this.mInfo.yDpi = this.mPhys.yDpi;
this.mInfo.touch = 1;
this.mInfo.rotation = 0;
if (!"270".equals(str))
break label224;
this.mInfo.rotation = 3;
}
while (true)
{
return this.mInfo;
label224: if ("180".equals(str))
{
this.mInfo.rotation = 2;
continue;
}
if (!"90".equals(str))
continue;
this.mInfo.rotation = 1;
continue;
label264: this.mInfo.type = 2;
this.mInfo.name = LocalDisplayAdapter.this.getContext().getResources().getString(17040668);
this.mInfo.touch = 2;
this.mInfo.setAssumedDensityForExternalDisplay(this.mPhys.width, this.mPhys.height);
if (!"portrait".equals(SystemProperties.get("persist.demo.hdmirotation")))
continue;
this.mInfo.rotation = 3;
}
}
I found this code in services.jar/display/localdisplay... How it modify to get portrait orientation when hwrotation=0???/

[MOD][CM12][COLOROS 2][HYDROGEN OS] Splash Screen Image Injector v1.2

This is a program that I wrote to decode the newer style "logo.bin" files used in some OPPO, and OnePlus devices. Please read below so you can better understand this type of encoding being used:
What Is A Raw Image?
A raw image, whether it be a file or an image in memory, is simply pixel data. There is no extra information like width, height, name, end of line... Absolutely nothing, just pixel data. If you have an image that is raw and the resolution is 1080x1920 and you are using a typical RGB24 or BGR24 (like the ones used here), then your exact filesize or size in memory will be 1080x1920x3! We use 3 here because there is one byte for the R or red component, one for the G (green), and one for the B(blue).
What Is A Run Length Encoded Image?
A run length image encoding uses a count ;usually a single byte (char), 2 bytes (short int), or 4 bytes (long int); and then the pixel components. So instead of writing out 300 bytes of '0's to make a line of 100 black pixels. Black is RGB(0,0,0). You could encode this as 100, 0, 0, 0. And only use 4 bytes of data to get the exact same image as the 300 byte raw image. All the run length encoding I've found, except the Motorola style which is a little different, use a run length encoding that is pixel-oriented like this.
Now I've figured out this new one and it is a byte-oriented run length encoding. This is for runs of bytes, not pixels. You may think, well whats the big deal? When you add a little area of color, you increase the run length encoded image in you logo.bin immensely! You use 6 bytes per pixel if there aren't any runs of color data. If you had an image that was a 1080x1920 black image with a 25 pixel wide, by 25 pixel high red box in the middle. The encoder would be doing runs of black data efficiently until it reached the red area.
.....0 255 0 255 0 255 0 255 0 255 0 99 /// we've reached the top left corner of the red square /// 13 1 30 1 255 1 // << that was just one red pixel!! in bgr color order (13, 30, 255) <<// And it keeps going through the rest of the red pixels on that line using 6 bytes per pixel, which is the opposite of compression. Before reaching the red square the encoding was decoding to 255 zeros over and over, until finally 99 zeros. 255 zeros is 85 black pixels stored in just 2 bytes!
This type of encoding is only good for grey scale images. It is not good with color, but it still will handle color of course. In grey scale, the Red, Blue, and Green data components are always the same values. All the way from black (0,0,0) to white (255, 255, 255); including every shade of grey in between>>>(1,1,1) (2,2,2) (3,3,3)....(253, 253, 253) (254, 254, 254)<<<
One other difference in this method of run length encoding is that the color byte is before the count, which is backwards from all of the other methods.
The attachment contains the C source code (which is also in the 2nd post) and the executable that was compiled using mingw32 on a 64 bit Windows 7 PC. The PNG library that I used is LodePng, the source is in the download.
To use logoinjector:
Decode your logo.bin:
Code:
logoInjector.exe -i logo.bin -d
All the PNG 's will be extracted from logo.bin. Edit the PNGs that you want to change...
Note:
Your original "logo.bin" file is never changed, it is just read. If the file you try to load isn't a logo.bin file, or if it is the older style, then the program will tell you and exit
Inject the image(s) back in to the logo.bin:
Code:
logoinjector.exe -i logo.bin -j image_name_1 image_name_3....
To list whats in your logo file:
Code:
logoinjector.exe -i logo.bin -l
For a more detailed list:
Code:
logoinjector.exe -i logo.bin -L
If the colors are messed up use the "-s" switch while decoding.
Code:
logoinjector.exe -i logo.bin -d -s
If you had to use the "-s" switch to decode properly, you'll have to use it to inject also:
Code:
logoinjector.exe -i logo.bin -j image_name -s
Note:
With version 1.2, you can put as many names after "-j" as you want, and it's not case sensitive. You also don't have to put the whole name. If you just put "-j fhd" every image in the logo.bin that starts with "fhd" will be injected. There has to be a PNG with the name in the directory though
The size of your modified.logo.bin will displayed along with the original size, if everything went good. Please know the size of you logo partition. I made this program to encompass any device using this format, and there is no set size of the logo partition between devices. Fastboot will just error out if you try to flash data bigger than the partition before it writes anything. But if someone gets brave and tries to "DD" to the logo partition, it could get ugly.:cyclops:
Flash the "modified.logo.bin" file through fastboot.
v1.2
made it possible for multiple injections in one command
doesn't add png to the decoded png if it was already in the name
fixed out of scope with image 26 in OPPO find 7 logo.bin
added LodePng source in the download
made the default color order BGR
displays the modified logo file size as well as the original file size
runs the modified.logo.bin back through the list function after injecting
checks the number of offsets between the original and modified logo.bin
Use this at your own risk.
Always make backups.
Always.

Interesting Can you tell me where do I find the logo.bin in my boot.img. I've extracted mine and don't see any sign of logo.bin. I own a OnePlus 2

Did you download a system image? If so, unzip it, and look for the folder "firmware-update". The logo.bin should be in there.

Works well for me! Thanks!

Thanks!! Removed this:
This is untested on the oneplus 2, however I've looked at the logo.bin from your firmware and it is identical to the newer oneplus one logo.bin. Let me know! Thanks!

how did you flash your modified logo.bin? if done through "fastboot flash logo logo.bin" it just quits with this error:
Code:

You have to flash "LOGO" partition and not "logo"

gotta love case sensitivity. thanks, it worked.
awesome mod

It worked, thanks

This will work with Stock Oneplus 2 rom too, right?
Edit:
Working fine with my Onelus2 too, just got logo.bin from my stock Oxygen rom. Thanks again.

From where can I extract my logo.bin from my phone? I dont have the stock rom with me. I need this from 1+2 if this works with it?

I went into changing the splash screen only after I'd already changed to custom rom ( bliss 6 ), so I didn't had any official OPT rom zip.
I tried to use the "logo.bin.p" from latest OTA updates FROM HERE... but the LogoInjector telling me that "This is NOT a valid Logo.bin".
Solution I found -> I managed to EXTRACT THE LOGO.BIN FILE FROM THE OPT ITSELF !!!
I got it right after I read about this command and saw the "updater-script" from one of the official OTA updates that included a hint about logo.bin place in the OPT internal storage :
apply_patch("EMMC:/dev/block/bootdevice/by-name/LOGO:305152:567b5d4deed7f4875809ae8b7f071ab38e5a94d5:305152:16c76f9c0cadf8be18eed0961dfbcf3b7bd0aacf",
"-", 16c76f9c0cadf8be18eed0961dfbcf3b7bd0aacf, 305152,
567b5d4deed7f4875809ae8b7f071ab38e5a94d5, package_extract_file("patch/firmware-update/logo.bin.p"));
Click to expand...
Click to collapse
so... how to extract to logo.bin ?
Note: If you don't know what you're doing - DO NOT DO IT ! DD command is DANGEROUS !
Using adb open shell and run the following command:
dd if=/dev/block/bootdevice/by-name/LOGO of=/sdcard/logo.bin bs=305152 count=1
Click to expand...
Click to collapse
This will create a "logo.bin" file inside the root of your internal memory aka /sdcard folder.
I got from that the following image files list:
Resolution - Offset - Name
1080x1920 | 0............ | fhd_oppo_1080_1920_result.raw ---> THE SPLASH IMAGE !!!
536x60.........| 65536 | fhd_at_536_60_result.raw
300x1020....| 75264 | fhd_charger_300_1020_result.raw
1080x1920 | 89600 | fhd_fastboot_1080_1920_result.raw ---> THE FASTBOOT IMAGE !!!
1080x1920 | 145920 | fhd_lowpower_1080_1920_result.raw
392x66 ........| 277504 | fhd_rf_392_66_result.raw
487x69 ........| 285184 | fhd_wlan_487_69_result.raw
Note, inorder to load the png to the logo.bin you need to rename the png you make as *.raw according to this list above.
Now... inorder to "flash" the logo.bin back to the OPT I use the attached zip.
you only need to add "logo.bin" to the root of this zip, then flash it through TWRP.
@makers_mark - once again, after your OPO development - Thanks A LOT for developing & sharing with us LogoInjector for the OPT as well

@makers_mark
Could you make one for oneplus3?
Thanks in advance.
logo.bin for oneplus3 is attached.

[MOD][SPLASH][OP3] Splash Screen Image Injector

This is a program that I wrote to decode the newer style "logo.bin" files used in some OPPO, and OnePlus devices. Recently I have updated it to work with the OnePlus 3. It is backwards compatible with the old encoding. Please read below so you can better understand this type of encoding being used:
What Is A Raw Image?
A raw image, whether it be a file or an image in memory, is simply pixel data. There is no extra information like width, height, name, end of line... Absolutely nothing, just pixel data. If you have an image that is raw and the resolution is 1080x1920 and you are using a typical RGB24 or BGR24 (like the ones used here), then your exact filesize or size in memory will be 1080x1920x3! We use 3 here because there is one byte for the R or red component, one for the G (green), and one for the B(blue).
What Is A Run Length Encoded Image?
A run length image encoding uses a count ;usually a single byte (char), 2 bytes (short int), or 4 bytes (long int); and then the pixel components. So instead of writing out 300 bytes of '0's to make a line of 100 black pixels. Black is RGB(0,0,0). You could encode this as 100, 0, 0, 0. And only use 4 bytes of data to get the exact same image as the 300 byte raw image. All the run length encoding I've found, except the Motorola style which is a little different, use a run length encoding that is pixel-oriented like this.
Now I've figured out this new one and it is a byte-oriented run length encoding. This is for runs of bytes, not pixels. You may think, well whats the big deal? When you add a little area of color, you increase the run length encoded image in you logo.bin immensely! You use 6 bytes per pixel if there aren't any runs of color data. If you had an image that was a 1080x1920 black image with a 25 pixel horizontal line in the middle. The encoder would be doing runs of black data efficiently until it reached the red area.
.....0 255 0 255 0 255 0 255 0 255 0 133 /// we've reached the top left corner of the red line /// 13 1 30 1 255 1 // << that was just one red pixel!! in bgr color order (13, 30, 255) <<// And it keeps going through the rest of the red pixels on that line using 6 bytes per pixel, which is the opposite of compression. Before reaching the red line the encoding was decoding to 255 zeros over and over, until finally 133 zeros. 255 zeros is 85 black pixels stored in just 2 bytes!
This type of encoding is ONLY good for grey scale images. It is not good with color, but it still will handle color of course. In grey scale, the Red, Blue, and Green data components are always the same values. All the way from black (0,0,0) to white (255, 255, 255); including every shade of grey in between>>>(1,1,1) (2,2,2) (3,3,3)....(243, 243, 243) (254, 254, 254)<<<
One other difference in this method of run length encoding is that the color byte is before the count, which is backwards from all of the other methods.
The attachment contains the C source code (which is also in the 2nd post) and the executable that was compiled using mingw32 on a 64 bit Windows 10 PC. The PNG library that I used is LodePng, the source is in the download.
Big thanks to @scoobyjenkins for testing the old program on the op3 and sharing his results!! Also for testing this new version too!!
To use logoinjector:
Decode your logo.bin:
Code:
op3inject -i logo.bin -d
All the PNG 's will be extracted from logo.bin. Edit the PNG(s) that you want to change...
Note:
Your original "logo.bin" file is never changed, it is just read. If the file you try to load isn't a logo.bin file, or a different style, then the program will tell you and exit. This version is backwards compatible with the last OnePlus/OPPO encoding method. The only one it won't do, is the original one, that was not encoded, it was just pixel data.
Inject the image(s) back in to the logo.bin:
Code:
op3inject -i logo.bin -j fhd_oppo fhd_at
To list whats in your logo file:
Code:
op3inject -i logo.bin -l
For a more detailed list:
Code:
op3inject -i logo.bin -L
If the colors are messed up use the "-s" switch while decoding.
Code:
op3inject -i logo.bin -d -s
If you had to use the "-s" switch to decode properly, you'll have to use it to inject also:
Code:
op3inject -i logo.bin -j image_name -s
Note:
You can put as many names after "-j" as you want, and it's not case sensitive. You also don't have to put the whole name. If you just put "-j fhd" every image in the logo.bin that starts with "fhd" will be injected. There has to be a PNG with the name in the directory though
The size of your modified.logo.bin will displayed along with the original size, if everything went good. The 'splash' partition is 16 MB on the OnePlus 3. If you use too much color on too many of the 7 images you will easily go over 16 MB. The program will tell you and delete the "modified.logo.bin" that was created. If for some strange reason you would like to keep it, use the "-B" flag on the command.
Flash the "modified.logo.bin" file through fastboot.
Use this at your own risk.
Always make backups.
Always.

The logo.bin you supply isn't ever changed by the program, it is just modified on your computer, then reinstalled on the phone. Unless you are talking about acquiring the logo.bin in the first place? In that case check out this guide. The partition that you'll be trying to get is the "splash" partition, and that is your "logo.bin":good:

Does this mean we could potentially port this over to the OP3 and retain the smooth/flickerless transition from the splash screen to the bootanimation? http://forum.xda-developers.com/moto-e-2015/development/mod-nexus-6p-logo-bin-bootanimation-t3262923

If you wanted to use this logo injector to put a Google splash in your OP3 logo.bin so it matches a Google boot animation then I don't see why not! No porting needed as such, just extract the logo from the Nexus logo.bin, make it 1080x1920 and have at it!

Splash screen for FreedomOS users.

Thanks @makers_mark for this tool !
I have compiled a linux version, see here
https://gitlab.com/Nevax/FreedomOS/blob/master/build/tools/op3injector

Flashed FreedomOS which came with a splash screen with no warning while flashing, could someone provide me the stock logo.bin file? Thanks in advance.

Thanks a lot for your work!! Will flashing this remove this Bootloader unlock warning??

@makers_mark is there any way to make -j compatible with directories? I have built this binary for android to work with my app and I already managed to add support for custom output directories but -j does not support directory names at all!
While this: "LogoInjector -i files/LOGO.bin -j 1-logo.png 4-fastboot.png" works fine, this: "LogoInjector -i files/LOGO.bin -j files/1-logo.png files/4-fastboot.png" does not... it throws an error saying: "files/1-logo.png is not in the logo bin" because it's actually looking for the string "files/1-logo.png" in the logo.bin and not "1-logo.png".
I tried fixing it but was unable to do so

[TOOL-TESTING] dirtydump (a way to dump boot or recovery for every un-rooted device)

Hi,
A little tool or frontend that I've made and share to the community.
Intro
If you are like me :
Searching a way to backup your device, try some tools like SP Flash Tool, or MTK Droid Tools (for generating a Scatter File).
I have found a lot of thread, but I've allways got a dead end or a risk to brick the device (Never take a risk to brick your device if no stock rom available or backup).
A few days ago, i've found this thread : https://forum.xda-developers.com/v20/development/h918-recowvery-unlock-v20-root-shell-t3490594
It's not for my device, it's maybe not for your device, but help a lot to do our need. This exploit work for everyone and what to do the little tools below.
What's the change ?
Instead of that does jcadduono (a big thanks to him), via applypatch, it don't patch the recovery partition to run an Android in Permissive mode, my applypatch only open and read the boot or recovery partition and display all data to logging (binary converted to hex value).
Yes, I know, logging is not for that, it's realy hard-core, but it's the only way working. I've tried with socket, but SELinux in Enforced mode don't allow this.

Don't laugh please, I am very new in C
Ok, but about the tool ?
The tool is a frontend and easy to use, it copy exploit files for you, run exploit, read logging from adb and do the revert of applypatch (Convert hex to binary and write them to the image file) and finaly reboot your device when it's finish.
An example here :
Code:

How to use ?
Extract all files from archive attached below in a directory of our choice.
./dirtydump boot : dump boot partition and store it to ./boot.img
./dirtydump recovery : dump recovery partition and store it to ./recovery.img
When all done, you have all to make your Custom Recovery for your device.
Requirements
<dirtycow> capable device.
Working adb (adb devices to check)

Note :
There is only linux binary, the windows version come soon.
(I don't know why Windows don't work as expected :x)
If you are interested by the source code, I can attach it.
Tested and build from Ubuntu 16.04 (x64) / Code::Blocks & gedit.
If any bug, I will do the best to solve this.
So sorry for my english, or any misspelling :x

Hey man great work
I was in need of such a tool
I needed the recovery partition for andromax x58
Though I dont own the phone its for someone(yeah you understand it right)
And now finally ported Twrp to it

please make compatible for 32 bit device

Hi,
Normaly, it may work for 32bit device, but can't test it :/
Can you give me error log, text displayed on your terminal please ?
And if possible, what do you have when you do : "adb shell uname -a" ? (because I detect 32 or 64bits device by this)
Regards,
Vincent

could you please post the dirty dump executable source code so i can port it to windows?
or just tell me how you determind what binary the device needs?

The Hard Gamer said:
Hey man great work
I was in need of such a tool
I needed the recovery partition for andromax x58
Though I dont own the phone its for someone(yeah you understand it right)
And now finally ported Twrp to it

Hai Bro,what command you issue in linux to run ?
Thks

Hmm this is awesome except the part it doesn't work on Ubuntu 14.04 and source code need gcc-4.9 to build (not sure).
Anyway I will install Ubuntu 16.04 to make new things to LG K4 (2016) [MTK MT6735m], good job thanks for it

@Vince_02100 what compilers did you used to applypatch and app_process64?
I need to compile a version to armv7(aka 32), since my current device (the LG K4) have a x32 Android and a x64 CPU.
I'm improving your dirtydump but with limitations since I don't know much about C/C++.
Please reply or PM me, anyway I will try my best to make it x32 support

@Vince_02100
My question is, did you base the operation of your tool on the dirtycow exploit? Seems like it because of its name and reference to jcadduono.
This is actually awesome then because I have a tool very similar only it works as a shell command handler. The Greyhat Root Console essentially is it's own Terminal Interface specifically to use dirtycow for root shell commands.
I only bring that up because Stock OEM builds that are dated October 2016 or later pretty much can't utilize CVE-2016-5195. Some didn't get patched that soon but most did. The rule of thumb I've always had when working with Dirtycow is to use stock builds from September 2016. Since they are the most up to date builds still vulnerable. I don't know how many people reading this thread know that.
Here is the thread I made where @droidvoider explains how to use the Greyhat Root Console: https://forum.xda-developers.com/android/help/injecting-root-setting-selinux-stages-t3573036
The thread also details our journey into modifying the Device SEPolicy using the console in order to elevate our normal user privileges. We have the instructions to build the Console for both 32-Bit and 64-Bit Builds of Android 5.1.1 & 6.0.1
I think the source code and our thread may just give you some good insight going forward with your tool, even though The Greyhat Root Console was developed on an AT&T Galaxy Note 5. That thread is a gold mine for dirtycow information.

Thanks for your great tool and explanation @Vince_02100. I'm researching to dump boot, recovery for Onkyo DP-CMX1 to make custom TWRP. I have some stupid questions and need your help like following:
1. Tool will not break system partition and it can boot normally after dumping recovery, boot?
2. I don't have root so how can I copy dumped files: ./boot.img , ./recovery.img to /sdcard or to computer? Do I edit your code
fp = fopen(blockDev, "r"); to make it write to /sdcard/boot.img?

Question Can any help with unlock bootloader menu

When I reboot into the "secret menu I don't have the option to unlock the bootloader I bought it directly from Samsung website

Maybe it makes sense if you give more details about your "plan"...
Because it makes at the moment no big sense without Firmware... Kernel and/or knowledge...
Only if you want kill your device.
Only my personal "feeling" about your question...
For other users... here is the """Secret""" in Video:

Looks like it could be harder since Tizen... A Stock Firmware for netOdin/Odin not available yet... B Combination Firmware not available yet C FOTA Delta File for study I have...

You don't need details about my plan To answer my question. All I'm asking is if anyone knows why I do t have the option to unlock the bootloader in the boot menu. It's an unlock galaxy watch 4 bought from Samsungs website not carrier specific. Is anyone else in the US missing this option

Its LTE = Security +1
Oh US LTE + + Security +1
It makes 0 sense if you have nothing to flash...
No Kernel nor full Firmware...
Thanx for your cooparation.
If I am wrong and you have Firmware and/or Kernel to flash...
Feel free to share your files...
Best Regards

Btw...
IMHO also other ways possible to reach this option... with ADB maybe...

Maybe via reboot...
Oh I know.... your project is Top Secret.

Your right I can't flash until I have kernel or full firmware but I would also like to no have to jump through this hoop when it does become available. That being said that is why I'm interested in figuring this out now instead of later. And yes I can use adb to boot to the boot menu but that still doesn't solve the problem of not having the bootloader unlock option

Maybe you know Samsung Phones and OEM unlock in Developer Mode...
Maybe you ever heard of fastboot...
Maybe it work...
Code:
fastboot oem unlock
Dangerous!
OWN risk!
No idea... never tested...
Best Regards
