DO NOT UPGRADE VIA OTA TO ANDROID OREO (8) (firmware 2000+) OTHERVISE YOU WILL BE NOT ABLE TO FLASH THOSE ROMS, UNLOCK OR TO DO ANYTHING NON OFFICIAL, UNLESS YOUR BOOTLOADER IS UNLOCKED
Models description:
SS2- 4gb/64gb
SAT -6gb/128 gb
DONT MESS!
Dedicated to XDA users!
Drivers and OST portable (don't use other versions of OST) press launcher.exe to install

Official S2 oreo updates:
Before you go
If you are on Android 7 after update to Android 8, you will be not able to unlock bootloader for free!
Firmwares for Service downloader:
Oreo SAT (CN) SAT-2140-0-00CN-B01
Oreo SS2 (CN) SS2-2140-0-00CN-B01
Oreo SS2/C10 (EU) SS2-2140-0-00E0-B02
Can be downloaded here: https://fih-firmware.hikaricalyx.com/sharp_en.html
To be flashed via this cracked OST 6.2.8 (note that you have to unlock bootloader and bootloader critical to be able to flash): here

Instruction: SAT owners - how to go back to stock Oreo 8.0 by @paulzie

Guys I don't support official updates!!!!
Instruction how to get back from offical SAT/SS2 oreo WITH UNLOCKED BOOTLOADER:
-Download twrp from here https://xdaforums.com/showpost.php?p=76412381&postcount=288
-Flash twrp from fastboot: "fastboot flash boot filename.img"
-Get Bootloader_oldservice.zip for you model from here https://xdaforums.com/showpost.php?p=76412178&postcount=287
-flash zip from TWRP.
-now you are able to flash OST ROMS after reboot.
CUSTOM ROMS:

FOR SAT AND SS2- OFFICIAL BASED ROMS (FOR OST) (for unbricking and downgrading. incl 9008 mode) :
RECOVERY:
There is no universal recovery, cos each version of rom include different kernel builds, if we use one twrp version (with for example version of 135E), wifi will work only in 135E and F versions.
So better wait for Oreo updates custom rom finals that will use same kernel and vendor versions.
BOOTLOADER UNLOCK:




@C10 Bootloader unlock guide

@SS2/SAT Bootloader unlock (if you have unlockcode.bin)

1. Get installed ADB/Fastboot driversand cmd - you can use OST portable (above)
2. Enable Developer optionsin android and usb debugging. Reset phone to fastboot (downloadmode) by "adb reboot bootloader" or by buttons combination..whatever.
3. Cpy unlockkey.bin to fastboot folder and type" fastboot flash unlock unlockkey.bin". You should have response "OK".
4. use fastboot-android.exe from SUT (OST portable folder). Type command " fastboot-android flashing unlock_critical". If its ok - phone screen should give a message about Bootloader unlock.
5. Enter fastboot again (download mode) and type" fastboot flash unlock unlockkey.bin". You should have response "OK".
6. Type command " fastboot oem unlock-go". If its ok - phone screen should give a message about Bootloader unlock.
7. Now you can use my OST nb0 roms to flash via SUT.

@SS2/SAT Bootloader unlock (for Android 7.1)
Download and extract attached zip (SS2- Sharp_ss2_boot_unlock_files.zip, SAT -Sharp_sat_boot_unlock_files.zip) . Manage to run windows cmd. Adb and fastboot drivers installed as mandatory,
1. Enter fastboot mode: connect usb, power off prone or restart same time pressing VOLUP + POWER, on Logo release power button. You have to see "Download mode" on screen (same thing you can do it from android with adb command: "adb reboot bootloader")
2. First of all check if you have tryes left in device-type:
"fastboot.exe oem cert_timecount get"
When is 0 you will be not able to unlock (unless you make changes) so STOP HERE! and visit here
if >0 then go to step 2.
2. Enter cmd in console: "fastboot getvar productid" -> you will get 16 digits serial number
3. Convert serial number to md5 hash ( you can to here https://www.md5hashgenerator.com/)
4. Enter cmd in console: "fastboot oem dm-verity [md5 hash generated from serial number (without quotes)]-> you should see "OK" response if you done it ok.
5. Flash this bootloader. Enter cmd in console: "fastboot flash abl unlock.elf"
6. Reboot to download mode again - enter cmd: "fastboot reboot-bootloader"
7. After reboot, enter in cmd:"fastboot oem unlock" - Get screen with unlocking!
8. Get unlock to flash critical (bootloader) partitions: "fastboot oem unlock_critical" - now you can use fastboot flash abl (or xbl) files.
Note: after accepting unlock popup on screen all data on phone will be erased!!!
When you have unlocked device repeat step 2 with commands
"fastboot.exe oem cert_timecount set 100"
I recommend to type above command each time you use fastboot, because each command used in fastboot makes this value less than before, and if it reaches 0, you will be not able to do anithing with most oem commands
You can relock bootloader anytime by cmd: fastboot oem lock
Happy rooting!

Upd Root Sharp Aquos s2 (only model SS2(4gb/64gb))
BEFORE YOU GO UNLOCK BOOTLOADER FIRST!!!

Unbrick Sharp Aquos s2 (only model SS2(4gb/64gb)) in 9008 mode:
QPST backup I made from ss2 135C rom. https://drive.google.com/file/d/1q9elokuWhj_hKPNYi0LguJhCzZWHc-Md/view
Backup is for 4gb/64 model not for 6gb/128gb

Enter manually HS-USB 9008 mode on Sharp (SS2/SAT):

I use this cable
Methode 1
1. Enable Developer settings in Android and USB debugging
2. Connect usb mod cable (don't cut wires together yet).
3. On pc in adb type: "adb reboot edl"
4. SAME TIME when you pressed enter after above command, cut green+black wires on USB.
5. Release wire, if you have done it on time, you will get HS-USB Diagnostics 9008 device in Device Manager.
Methode2
1. Open phone cover

Methode3 (if you have unlocked loader)
fastboot oem reboot-edl


Many thx to @hikari_calyx for useful files for community.

    03.06.18 Unified treble rom v3. for Sharp Aquos S2 (SS2/SAT)

    NOTES BEFORE YOU GO:

    This ROM pack is based for flashing via OST. After flashing you will be not able to flash anytning via OST. Only way to return to OST is to flash included zip with old bootloader from TWRP.
    ROM pack is intended for Sharp Aquos S2 (model SS2 and SAT) with UNLOCKED BOOTLADER in case of using with LOCKED BOOTLOADER I warn you- if you damage boot partition or flash it with non working twrp -phone will stuck in Download mode- only way to unbrick is to open phone cover to disconnect battery.
    READ FIRST PAGE HOW TO UNLOCK BOOTLOADER
    Everything you do you do on own risk.
    you can unlock bootloader after flashing of trebled by this instruction (SS2 now only)

    Pay attention to filenames: "SS2"- 4gb/64 model, "SAT"-6gb/128"


    ROM's and updates for trebled v3 Updates, recovery and other files on next post :https://xdaforums.com/showpost.php?p=76412381&postcount=288

    Inluded recovery gives to you ability:
    -to install treble system images;
    -install vendor images updates;
    -switch a/b systems ( you can have two different OS's preinstalled)
    -install further updates without OST;

    V3
    Base:
    -Android Oreo update S3 1320WW with gapps.
    -Vendor and kernel SS2-2100CN, SAT-2120;
    -modem SS2-135EWW, SAT-2120;
    Build specifics and modifications:
    - TWRP with a patched kernel for magisk;
    - Encryption of data is enabled;
    - Enhanced stock camera;'
    - Modifications to SystemUI;
    - Fix microphone mixer_path.xml (Vendor SS2 / SAT)
    - Custom size of the status bar (see values in build.prop)
    - Double tap to turn on / off the sensor button (SS2 / SAT kernel)
    - Increased max. current for fast charging (kernel SS2 / SAT);
    - Stepping for fast charging (SS2 / SAT kernel) is included (which gives an unknown);
    - thermalconfig (vendor (SS2) - finally opened a big cluster (clamped completely by the manufacturer) - now the device absolutely does not lag. corrections in the configuration of charging;
    - Disable fingerprint gestures in the soft key mode;
    - Fingerprint navigation file moved to vendor/usr/keylayout to work with treble;
    - Fix selinux associated with a bug of long camera loading when using magic and with third-party cameras (vendor SS2 / SAT);
    - Disable signature verification of system applications;
    - Fix selinux rights for modified applications with uid: 1000 (vendor SS2 / SAT);
    - Other bug fixes siui and add functionality from s2 firmware.
    - 100% firmware is ready to use treble images. Extremely not recommended with locked bootloader!
    - Boot-complete fixes when using system treble image (vendor SS2 / SAT) previously encountered bug with reboot in Download Mode and wiping boot; (so far tried everything works)

    To make Android Pay working (getting the "green" status safety.net):
    -install Magisks.apk > press - Installation button> The 3rd (recommended method.) (it is necessary to do every time after the wipe date)
    Specially for the Android Pay, the name of the model, model and fingerprint version are from s3, necessary for checking safety.net
    s2 with Oreo were not certified in Google, which explains the absence of ww firmware- explains why treble images wont work with Android Pay too

    Bugs:
    Only treble roms with pin or pattern enabled, will be asked for unknown pincode in twrp recovery.

    How to downgrade of update this rom after v1, v2 to use OST:
    Flash this old bootloader file SAT-Bootloader_old_service.zip for SAT and SS2-Bootloader_old_service.zip from twrp
    OBNLY AFTER -flash for example 135E for OST for SS2 or 127N for OST for SAT, so after you will be fully on stock Android 7.1




    How to install:
    1. Unlock bootloader (if you not able to unlock -read warning above)
    2. Download OST portable and run launch.exe. It will install all needed drivers. https://drive.google.com/open?id=1X9sihCc_RzTfSe6PhW9saZbnRsMLK4j7
    3. Download V3.1 nb0 for SS2 https://drive.google.com/open?id=1n4lAZDlgjiEigyWSH5IKBMXxdK6wweFS
    3. Download V3.1 nb0 for SAT https://drive.google.com/open?id=1akaE0FATlN18glFQI5P06Oa5-h4flPNO
    4. Enter "Download mode" (Hold Vol down + power at reboot while connected via usb OR "adb reboot bootloader" via usb debugging
    5. Install from OST with options : Normal Download, Erase data

    SS2/C10 Trebled V3.3 (to be installed via twrp)

    Hi this is full twrp install rom with full firmware from 2130 to be installed via TWRP (part1) and latest post of s3 1320 ROM( included in my backup before) (Part2)
    ___________________________________________________________Part1_________________________________________________________________
    You must have SS2/C10(not SAT) and unlocked bootloaderyou can also try with locked bootloader but better don't do this

    Installation 2130 trebled:
    - SS2-C10-trebledV3_3.zip https://drive.google.com/open?id=1UK5u9tFX1lrYeC_kH_48jO8WRhXItvVL
    -install zip from twrp recovery (a7 or Oreo no matter) this is full rom;
    -switch to slot A before installation and after - via |reboot| menu in recovery
    -format data (or wipe) must! or you may have battery drain and some problems with programs;

    Advantages of 2130:
    -Full translations to all WW languages;
    -potential support of B20 and C10 fitches;
    -Nothing more than 2080 WW for SS2, besides of WW launcher :)
    -even vendor has 100% same hardware drivers as on 2100 CN (trebled 3.1), so no camera quality miracles.
    -and even s3 port is more interesting with its gestures.

    Fixes:
    -(SS2) hwid and config of kernel sees now SS2 CN as C10. I found hardware of C10 and SS2(CN) is similar, so replaced factory config for - kernel and modem and rf- seems is now as C10. So check if you have network!! You may have B20 now ;) from other side you may have problems with network now :) I don't have.
    -added usb config with diag mode: "sys.usb.config diag, adb". So you can experiment with nv's.
    -added call recording, launcher, robo :) , apptwins (from tw version);
    -removed debug software;
    -updated twrp-boot to magisk v17;
    -added pickup phone to see not's on lockscreen;
    -enabled gestures menu - to hide sofkeybar.
    -patched kernel and android to have faster fingersensor wakeup, also added double tap on figersensor wakeup (as usual);
    -few more hidden settings;
    Vendor fixes:
    -dpi 440;
    -pathed vendor sepolicy and services to use system apk's with different signatures;
    -fixed problems with vendor (that were in 3.1 trebled roms);
    -enabled more compatibility with GSI images;

    So now you are using C10!

    Note default C10 firmware wont enable C10 on your SS2-CN ! Don't waste your money for Ntool!!

    ___________________________________________________________Part2_________________________________________________________________
    You may have SAT/SS2/C10 to flash it.
    If you don't like C10 2130 firmware (personally me not) or you just using trebled 3.1 rom on your SAT/SS2/C10 -you can flash this twrp installation with system (and cda) from S3 port 1320:
    For SS2/C10 users I highly recommend to flash 2130 trebled firmware before
    This system I like more. Gestures and faster fingersensor, don't feel like Chinese SS2(C10) team come even close to this...
    Installation:
    -flashSS2-SAT-portS3-1380-system-cda.zip https://drive.google.com/open?id=1kKhVTyl4k6jq6rLX36PY34hMoKzVDSAS from twrp;
    -switch active slot to A;
    It can be also flashed for SAT or SS2 on older trebled rom.

    Official Firmware 135E WW installation via service tool

    ONLY FOR SS2 (4GB/64 SND630) MODEL!!!

    Files below are done by me and prepared for you. I don't own Sharp Aquos S2 myself (borrowed), device is only interesting for me for experiments. All sharing of information below must link to this message.
    I don't take any responsibility on bricked devices or by crooked hands.
    Do it on your own risk!!!

    This tool and rom are for normal flashing "from the box" and unbricking from fastboot or hs-usb mode 9008.
    How it works:

    2. Download SS2-135E-WW-open_bl.nb0.zip file and unpack nb0.
    3. Open SS2-135E-WW-open_bl.nb0 in OST and get next options:
