Below US snapdragon devices can be bootloader unlocked with above service as long as bootloader version meets below criteria. Bootloader version can be determined from the 5th character from the right on the baseband version or build number, in some cases from kernel version

Below Method is no longer supported if you choose to use the unstable method below you do so on your own

This method is brought to you entirely by @elliwigy He is the reason for this exploit and method.

With that being said, Extreme Syndicate Root is now available!

Before Starting This Process Get A USB2 Mini Hub You Are Most Likely Going Too Need It​

EXTREME SYNDICATE ROOT METHOD

​

OEM Toggle Does Nothing On US Model Phones

This root method breaks things and most likely will not be able to be used as a daily driver

You can be on any version bootloader. This will update you to V9 bootloader

This method will work if you are on Android 10 or Android 9 Pie but will put you on Android 8 Oreo. There is no root for Android 10 or Android 9 Pie

You will not be able to use magisk

You will not be able to flash full custom rom like Lineage or any other AOSP roms however GSI system images can be used

You cannot flash custom boot images or recovery images such as regular TWRP

Odin does not work on some later computers with USB 3.1 chip controllers the only work around is using a USB 2.0 mini hub

It is your responsibility to make sure you can use adb properly

Root will break things such as safetynet so deal with it

Disclaimer:

The Extreme Syndicate team and it's affiliates are not responsible for your actions or your device if any issues are to arise. You flash this and utilize these files at your own risk. You have been warned!

Notes:

- Safestrap recovery is now available with working MTP while in Safestrap

- This does NOT trip KNOX so don't ask.

- Bootloader is of course still locked.

- This uses some partitions from combo firmware which means 80% battery.

- Each variant will have its own post in its own download section. Download the right stuff!

* Variants this should work on are: N960U/U1/W, G965U/U1/W, G960U/U1/W. If you do not have one of these variants then this forum is not for you!

- Initial files/method will leave you on Oreo stock root.

- It works on latest rev's from rev1 up to the most recent revs.

- As of the initial first release, all variants have an issue with MTP not working except while in Safestrap

- S9 and S9+ also might have some issues with the selfie cam.

Downloads S9 Files:

Safestrap_S9_Cmd_Line.7z

Download S9+ Files:

Safestrap_S9_Plus_Cmd_Line.7z

Download Note9 Files:

-- Only For Bit 8 Or Lower

Safestrap_N9_Cmd_Line_Bit8.7z

Instructions to Inject Safestrap:

1. Download and unzip Safestrap_S9__Cmd_Line.7z for your device

2. Plug phone into computer and run Safestrap.exe

3. Follow instructions on screen to enable USB Debugging

4. Then from there the process will be mostly automatic just follow prompts on screen

5. When done flashing BootSwap file you need to hold the buttons to boot to recovery but since we swapped boot and recovery images it will boot system.

Instructions For Flash Rom:

1. Download below files and copy files for rom to phone system img and vendor img and odm zip

Downloads S9 Files:

Stock_Rom_G960.7z

GSI_Rom_G960.7z

Download S9+ Files:

Stock_Rom_G965.7z

GSI_Rom_G965.7z

2. In safestrap flash system img then vendor img and odm zip .

3. Choose data wipe and advance and check data

4.. Now reboot system you will have to hold buttons to reboot to recovery until you see safestrap splash then click continue.

You must do this on every reboot.

If you do not it will reboot to stock recovery. If it reboots to stock recovery just reboot system and hold buttons to reboot to recovery again.

5. When rom is booted up your computer will not recognize the phone for mtp file transfer. Adb does still work so you can transfer stuff that way (you need to switch to ptp transfer method in the dropdown) or use USB adapter and use a thumb drive.

6. Biometrics do not work so don’t try to setup fingerprint or face recognition.

The GSI rom mtp works GSI rom is rooted already just flash phhsupersu.apk found in GSI_Rom zip

If using other GSI roms you have too choose A_Only ones and will probably need to flash the Sh_Remover.zip found in the GSI_Rom zip
