You need to FORMAT DATA, It's in wipe, put format data (IT WILL WIPE EVERYTHING), and woah, there will be the main memory.

Well thnx for the reply I will give this a try but I don't think it will work because when I install the twrp the data value becomes 0, quick question before I try this by wipe everything you mean the phone right not the sd card am I right?

Alright, so final question before I give it a try, the only thing that I click to format is the data right or should I choose something else with it?

TWRP Unable to mount storage

Hi,
Noob here. I have a x727, bootloader is unlocked, twrp 3.0.2-0 installed, flashed rom fine everything working.
I went to do another backup today because I was going to flash an updated rom, but I'm getting this error in TWRP:
"Unable to mount storage"
when I try to do a backup. The "internal storage" shows (0 MB).
I also cannot see the files I transferred over to flash, I assume because it can't mount the partition.
How do I fix this? Thx in advance.

maybe u get encrypted ?

Shouldn't he wipe?

not sure how/if i got encrypted, never intentionally did so.

ok i guess it was easier than i thought...reflashed twrp and it works now. thx for the ideas.

wipe FORMAT DATA , please backup first .

I tried formating data and it works but when I restart to system and later on restart back into recovery the internal storage is 0 mb
But when I flashed a custom rom it worked (I dont like custom roms bec it has bugs and looks ugly)
I tried lineageOs

Then flash with Odin the Stock Firmware. And Start New...

Cannot access files unless in TWRP

Hello!
I tried to do a clean install of MIUI Global (10.3.11, which came with the phone). I didn't install any other ROM before in this device. Wiped eveything (data, system, dalvik etc.), then flashed the ROM and Magisk.
Now, when I connect the phone via USB I cannot access my files. It only shows "internal shared storage" on Windows, and it's all empty. When I try to transfer a file it shows nothing, the file just don't go. While in recovery I can access the storage and transfer files.
*I did activate USB depuration in developer mode.
*I did change de USB mode to "transfer files"
*I reinstalled the ROM several times.
Maybe it's something to do with the format type of the storage?
I'd try to do a ROM fastboot but I cannot find the fastboot version of MIUI Global for MI 9T.
Please, help

Did you format data? I think you forgot this part, format data then you can wipe it if you want.(formatting will delete everything from your internal storage ofc)

Ohk Let Me Help You .
Have You Advance Swipe the internal storage..then rebooted to twrp Before flashing the ROM !!

Thanks for the reply! Yes, I did.
It seems like the "/storage/emulated/0/........." is broken. I cannot do nothing on this folder. I tried to create a file/folder in it with Solid Explorer and it says that the directory wasn't found.
Any idea?

Noticed that when I try to wipe data after formatting it an error appears on TWRP: "error opening '/data/media' (No such file or directory". Is it normal?
Seems like the ROM isn't properly creating the directory, that's why I can't access it.
