03/2021 and still no ROMs for S7 Edge G9350.

Good phone, but with out new updates it becomes useless.... Why there is no lineageos for G9350?
Same question.
Is it impossible to port Android 10 for this device?
I hope someone comes out with a new ROM for us.
Currently using Trada ROM, its lagging too much now. Device seems unusable now. While Roms are being built for even S2 ☹️

    As a joke, here you go USA!

    It works for all USA variants of the S7 edge, but you can't flash it! Muahahahaha!

    Team Win Recovery Project 3.0.2-0



    This is for the Chinese SM-G9350 Qualcomm model only! Do not flash on Exynos models!
    If you have a SM-G9300 or SM-G9308, look here instead!


    WARNING #1: Flashing a custom recovery to your device will trip the Knox warranty bit on your phone. Check with your mobile provider to see if they will still cover warranty on Knox bit triggered devices. If you understand this risk, continue on.
    You generally don't have to worry, as it's incredibly hard to brick a Samsung device, and physical damage warranties should be exempt from Knox triggering.

    WARNING #2: The Galaxy S7 edge stock boot image has dm-verity, which prevents you from booting if you swipe to enable system modifications!
    SOLUTION: Follow the full rooting steps below in order to allow system modifications without the risk of a boot loop!


    WHAT IS TWRP?

    Oh come on, you know what it is - don't try to fool me!
    In case you're serious, though...

    Team Win Recovery Project is a custom recovery for Android devices.
    It allows you to back up and restore your data, flash custom ROMs to your device, repair broken file systems, and root your device.

    DOWNLOAD

    You can find the device page here:
    http://teamw.in/devices/samsunggalaxys7edgechina.html
    There is a download link there, as well as instructions on how to flash it.

    I highly recommend using Odin 3.12.3+ to flash when possible.
    You can find a zip containing Odin as well as Samsung's Mobile drivers here:
    https://build.nethunter.com/samsung-tools/

    FULL STEPS FOR OBTAINING ROOT

    Follow these instructions until someone nice comes along and makes a video from them (without ads):

    1. In your ROM, go to Settings -> About device. Tap 7 times on Build number to enable Developer options.

    2. Now go to Settings -> Developer options. (above About device)
      You need to enable OEM unlock, otherwise you might end up with boot problems or be unable to flash later on.
      Transparent.gif
    3. You will need to unlock your bootloader now. To do this, download the app "CROM Service By Samsung Electronics Co., Ltd." from the Galaxy Apps store and run it.
      Follow the instructions in the CROM Service app to allow your device to accept custom images in download mode.
      Transparent.gif
    4. Extract Odin_3.12.3.zip to your computer.
      Transparent.gif
    5. Install Samsung Mobile Phone Drivers for Odin to find your device.
      Transparent.gif
    6. Download a .tar image of TWRP for hero2qltechn.
      Transparent.gif
    7. Reboot your device into Download mode. To do this, select reboot from the power menu and hold the [Volume Down] + [Home] buttons while your device reboots.
      Once you reach the Download mode warning screen, press [Volume Up] to continue.
      Transparent.gif
    8. Open Odin and place that TWRP tar file in the [AP] slot and disable Auto-Reboot, then press [Start].
      Transparent.gif
    9. Hold [Volume Down] + [Home] + [Power] to get out of Download mode and immediately swap to [Volume Up] when the screen blanks.
      If you don't see then TWRP boot splash try again from step 7.
      Transparent.gif
    10. At this point, you will reach the screen asking you if you want to allow system modifications.
      By swiping right, you will trigger dm-verity, and if you don't follow step 10 you will be unable to boot!
      If you are going to root your device and follow the rest of these steps, then it is safe to swipe right and enable modifications.
      Transparent.gif
    11. If you want to be rooted with SuperSU:
      Download the latest SuperSU by Chainfire.
      Without exiting TWRP, transfer the SuperSU zip to your device over MTP* and flash it using [Install] in TWRP.

      If you want to be rooted with something else or just want a bootable system:
      Download the latest no-verity-opt-encrypt zip.
      Without exiting TWRP, transfer the no-verity-opt-encrypt zip to your device over MTP* and flash it using [Install] in TWRP.
      It will allow your system to boot after swiping to enable modifications or using backup/restore in TWRP.
      It should also allow you to use [Format Data] and prevent encryption, allowing you to use your data partition and internal storage inside TWRP.
      Transparent.gif
    12. Go to [Reboot] -> [System].
      Transparent.gif
    13. Wait 2-5 minutes for your device to finish setting itself up.
    * MTP, known as Media Transfer Protocol, is the same way you transfer files from your PC to your device when booted into system.

    I flashed this twrp but recovery won't boot. Get blue screen with red writing up top that says custom binary blocked by secure boot (recovery.img). I have gs7 edge AT&T version. Now what?

    this recovery is for unlocked bootloaders only. IE chinese and hong kong models only.

    I have the SM-G935U (Unlocked US Model). Could I flash the Chinese firmware via Odin and still use this method of rooting and flashing TWRP? They both have the same chip. Snapdragon 820 Chip. Will I run into bootloop sore any problems with my mobile data LTE? Urgent, thanks. If so which firmware should I flash Hong Kong or China (Open China) from SamMobile.
    Can't happen. Odin won't flash it and if you use FlashFire it will brick (hard brick, not fixable via Odin)

    The reason being that the partitions are different between ours and theirs.

    Mine shows up in stock recovery as g935PVPS5BQK1 . If I'm in right area then that's fine for me I'll continue as is but just wanted to make absolutely sure before I carry on.
