Maybe magisk? Since SuperSU is pretty much dead. Just a suggestion.
SuperSU is installing system mode, and you likely need to patch the boot.img and other things magisk patches (like dmverity)
Either flash clean stock firmware first, or unsu by Osmosis.

You're using an old SuperSU too. If you must use SuperSU, use 2.82 SR5 from this post.
SuperSU should work on Android versions up to 7.1.
But I recommend magisk.
Make sure your TWRP is up to date too.

Will you be updating the 1.3 build with this? Excuse my question if it's vague, I don't fully understand how ROMs are built. But I am loving your 1.3 build. Battery is amazing.

[ROM][TWRP]Lollipop Stock V20i-EUR-XX[ROOT][D855][JUNE27][OFFICIAL]

Firstly, you take all responsibility for using this work.
Love flashing ROMs and find it a hassle finding a computer and the time to reinstall genuine LG G3 firmware?
This ROM is for you!
This ROM lets you install the latest v20i european firmware without a computer but by using TWRP. And it is already rooted!
Steps:
1. Download the file
https://mega.nz/#!QYlh3Q7J!1cKq244pEOwD7GmyWbQzYkXBEt2_kKemzqEEGvHUkVI
2. Unzip it using your favourite file explorer. I use Root Explorer!
3. Place the contents in the following location (create folder if necessary!):
/storage/emulated/0/TWRP
4. Reboot into TWRP recovery
5. Factory reset
6. Click 'restore' and select the nandroid backup.
7. Boot into the latest v20i firmware with root!

For what I know the 20I is the newer for EUR. Looks like the changelog is bigger
Sent from my LG-D855 using Tapatalk
Yes, in UK, where I am, 20i is the latest ota version. Using this method saves loads of time so feel free to use, or not
Can someone point me out a changelog for LG OTA updates? Can't seem to find any.

can you replace this baseband (radio) with international baseband (20p) ?
to see what's the different if use regional baseband and international baseband.
I think the v20p thread had a list of ota changelog. You can flash another modem baseband if you have the zip file.

Opx twrp fail

Hello everyone.
I have problem with my OnePlus X. It's rooted and a week ago starts roll out new Oxygen 2.2. I get OTA update, but I can't install it. I understand, it's because of root, but I downloaded zip file and trying to install it via TWRP and it always say's FAIL. Even on FACTORY RESET. I read a lot of stuff but it's always the same. Flash custom recovery and install ROM via TWRP or CMW.
Can you help me?
Thanks
what are you flashing? the full ROM or the OTA? which TWRP are you using and what is the error message?
I was trying to flash OTA Oxygen 2.2 but it doens't work. So I tried full ROM (oxygen and Cyanogenmode) and it doesn't work too. I have TWRP v2.8.7.0 .

OTA can't work it's normal.
Full zip should but if not, you have to install Bluspark recovery.
twrp-2.8.7.0-onyx_f2fs_v12.img
Okey thanks a lot. I'll try it.

Just to be sure, You followed well the unlock bootloader / recovery install and root instructions? You didn't just do the oneclick root approach?
Not one click. Full root.
It' should work with the recovery I told you, as it worked with others....
I hope it will. Thanks a lot man.
Do one thing,
Flash blu spark recovery, Then choose the 2.1.3-X zip n in the next step "add zips" add 2.2 (latest one) patch which is about 40mb n flash both at once.. it will do it n u will b on Oos 2.2
YES! Got it. I downloaded full ROM 2.2 Oxygen and I did new recovery (blue spark) and it all works Thanks guys )

Magisk 16.0 Safetynet failed? (SM-J327P)

I'm having issues passing safetynet on a Samsung J3 Emerge while using Magisk. I have read thread after thread and their doesn't seem to be a fix. I'm not sure If it's an issue with samsung devices but as soon as I restore boot.img everything is works fine. Rather annoying to do so just to use a few apps that need root or won't work on rooted devices. I read in a forum that
I'm at the point of pulling my hair out due to frustratration. Any help would be highly appreciated.

Had you uninstalled any bloatware? If yes, then you need to reinstall it as a system app again to fool SafetyNet and make it believe that your device isn't rooted.

How to upgrade from rooted Andtoid 9 tab s6 rooted with odin but pc no longer availab

Ive rooted my SM-T860 using a Windows 7 laptop/Odin and Magisk before the Android 10 update. I no longer have the laptop.
Can anyone advise how I update to Android 10 without a PC if its even possible with my Tab rooted.
Is Mobile Odin an option?
I don't have TWRP installed only stock recovery.
Any replies are gratefully appreciated.
I'm thinking I should have used a different root method and installed TWRP, but I didn't, thanks in advance guys.
Hope everyone is doing ok.

You are going to need a PC. You will have to Odin back to stock at the very least.
Try FlashFire app from Playstore. If you are rooted it is only way to flash ROM without PC.

I brought mobile Odin a few years back, with no TWRP installed would mOdin or flashfire work ok do you think? Thank you for your help, I seriously appreciate it.

Thanks for the reply, why would I have to go back to stock first?
I really regret the root method I chose and ideally I would love to have TWRP and pass all device security checks etc.
I'm just really anxious and nervous to make a mistake that makes my device unusable :/
I miss kingoroot/towelroot/iRoot etc lol
