Just fixed mine by doing the bootloader unlock and root steps above,
setup the phone without Google but with debug mode enabled,
flash twrp,
format data (the one that makes you type yes),
setup the phone with Google and debug mode, then
reflash the firmware with Odin (stock BL, magisk_patched AP, stock CP, and HOME_CSC).

Now I have 108gb storage with root! I just have to hold volume up+power button every time I boot, though.

Could you please be more detailed in this steps?? I got this problems too. plz help.
read carefully every step bro. after flashing magisk patched then setup phone from beginning without setup google acount just skip, then check again by activating developer menu & usb debugging on. at the end reset from about menu..then phone's should reboot, after that install magisk manager then follow until finished process. & now after reboot u already got rooted beloved phone :cowboy:. congrats

Only the latest version from blackbuga, and yes, I can't access my internal storage through USB when in twrp. It doesn't bother me that much, because I only needed twrp to format the data so the storage goes back to 108gb from 32gb. Everything's been running fine so far.

but why u need twrp just for get normal storage.. while my storage going fine without twrp & i just try reset in finalizing process then install magisk at the end & everything looks good.
right now I'm just curious why there's no more dev interest in working on custom recovery & roms which is in other hand there's plenty developer working on galaxy s series with snapdragon soc with great support for official/unofficial builds whether twrp or cust roms. so sad considering the device is quite a potential to be developed :rolleyes::(

I just followed op's instructions in his A70 topic lol I get you. I came from iOS and I was really excited when I got the phone, but after seeing the development scene... I don't know, maybe it just has something to do with the phone's price being expensive and all that.

yeah it's possible for sensitive pricing from first launching. in my country first launching price going around $705 then after few month until approaching new device release info to be released in February. on new years then the price going down until just left $549,50 then i decided to bought it :victory:
maybe many people's thinking like me, wait & see before grab this phone's :laugh:

.
Actually, the truth is something else and the price range is not relevant at all.
If you have A series, it is low price range of Sammy phones and if you owned previously Iphone, you jumped "from horse to donkey".
Here you can find android ultra expensive devices successfuly rooted and in everyday ongoing development.
As pricey device is, more support you have ( All S,S+ and Note series, for example).
I have very expensive Galaxy Fold device...successfully rooted with regulary ongoing development, therefore, price is not relevant at all.

There on IOS is missing crucial users inteligence, knowledge and developers on IOS users market.
Simply said...they don't have and don't need developer oriented users and no quality devices to be upgraded or "pushed" further more.

Also...IOS is CLOSED SOURCE system not opened for free development because Apple can't make profit of that.

but what about this device? are u still make exception from regular ongoing development.. until now there's no famous developer that saw it for builds known roms out there although this doll already succesfully rooted, but none of them build us twrp with fully support & maybe one or two working cust roms
