How do I erase my internal SD card?

My phone is all messed up. When I plug into USB the only folder I see is the Android folder, and then the data folder. I can't access any of my other folders unless I am using Astro. I am trying to format my SD card to see if I can fix this. I went into CMW and formatted the data, the cache and the system. STILL all my files are there, and I still can't get them through USB. What am I doing wrong??? I also reinstalled my ROM and I wiped data/factory reset...

I believe there is a "wipe local storage" option (or equivalent) under "advanced" in CWM.

Nope, I only have
Wipe Devlik Cache, Wipe Batt Stats, Partition SD card (maybe that?) and other unrelated things. It's not under mount/storage either

Relock and unlock the bootloader.. That should erase the sdcard
fastboot oem lock
fastboot oem unlock
If that doesnt work, reflash to google stock images. Look into the guides available in this thread.

No need to relock/unlock.
Just use fastboot
Code:
fastboot erase userdata

Thanks! Is there a way to do it with plain adb instead of fastboot? in fastboot it keeps saying. "waiting for device"

Why don't you just format the drive in Windows? Seems like you're overcomplicating it.

In fastboot mode, go to device manager and update drivers. You need to install them twice to work

Wrong, doesn't work.
Can't format a MTP device.

Thanks to your tip I could erase the SD content! It's probably best to do this though:
Code:
fastboot format userdata

[Q] Strange missing free space?

I am using like 4 gigs on my main sd. It says I only have a gig left. I doubt my system is hitting 5 or 6 gigs. I'm using the Avatar rom. I attached a picture of my storage overview. I also formatted cache. Any ideas?

You are most like affected by the emulated storage bug. How to fix:
Have a card reader, and MicroSD to SD adapter
Back up all of you data to your computer
Update to the latest CWM or TWRP
Wipe Data \ Factory Reset
Wipe Cache
Wipe Dalvik Cache
Format /system
Copy a ROM and gapps to the external SD with the card reader
Flash ROM
Flash gapps
Profit!

Lemme get other people's opinions before I get drastic.

Get disk usage from the market. Run that and see what it shows you.

Agreed. OP, formatting /system and /data will resolve this issue.

Thanks, I'll give it a try and report back. Can I use the same rom?

Yes sir. Wipe data, wipe cache. Wipe dalvik. Format /system. Format /data. Flash rom. Flash gapps. Reboot. All this is done, of course, assuming you have the rom, gapps and perhaps a band road all on a micro sd card. Cheers

I wiped the data, /system, cleared the cache/dalvik and such. Flashed both and rebooted. It shows 12 gigs total space, 2.13 available. All my files are still there. Are they supposed to be?

No. There's wipe data and format /data in cwm. Did you do both? You need to.
Or are you twrp?

Fixed! This time, I formated /data, did a user data format, and wiped my /sdcard. It's all good now, thanks!

Well the thing that did it was wiping the /sdcard. I might have accidentally skipped over that, either way. Thanks for the help! I got everything back to the way it used to (with more space of course).

"Cannot mount internal storage" A3

When I go to twrp recovery and try to wipe internal storage or even see whats inside the internal storage folder it says "Cannot mount internal storage". Does anyone have a fix for this?

It's not a bug, the data partition is encrypted. It needs to be formatted.

Well that's the whole point. If it was mountable you wouldn't need to Format it.
Just Format it anyway, regardless of the mount errors.

Guys Please help. Unable To Mount... error. Tried everythng. Video given.

I have watched a lot of tutorials but nothing is working please someone help
I made a video of the problem and what I tried. Can anyone understand what happened
https://www.youtube.com/watch?v=VaN-y-Worlg
Update: In Data i Changed the file system and went back to original. Didn't work.
I even wiped system. But i guess the only problem is to fix the "data". Since it shows 0 Mb size. But i can't find any way or guide. The ones i did find are too advanced and use cmd commands and toolkits which i don't think an inexperienced user like me should be following.
Some background information: i attempted to install Open gApps and enable Camera2 API. I Entered "read only" mode.
The adb shell commands for enabling it wasn't working (some "proprietary" something shown )
So I tried another method. I downloaded the latest Magisk and flashed it. Then i tried gApps. I don't remember when i started to think what went wrong but yeah..

I found this and I think it may be related.
But I don't understand it properly.
And its and Old post for some other Recovery

Why did you wipe internal storage? And what are you trying to mount. If you are trying to install a new rom all you need to wipe is cache, dalvik, system and data. Wiping internal storage removes everything from the internal SD card and if you do this then you have no OS.

At this point i can't care less about the data in internal storage. I just need to flash the official MIUI ROM back, enable Camera2 API and live in peace. At this moment I'm halfway through downloading the ROM but I'm not sure if i can flash it due to the Mount Issue of internal storage. I plan on transferring it to my micro SD card and flashing it from there to System Image. Will it work? And Internal Storage formatting failed in case you didn't notice. Practically nothing worked except the file system change of "data". And even that didn't fix the unable to Mount issue.

Internal Storage

Help me please.
My phone is in a bootloop and twrp cant mount /data. I tried formatting and changing file system but it all failed. I cant flash rom in MiFlash and it says "flash xbl error" or "FAILED (File is too large to download)"

What did you do before the phone went into bootloop? Also did you format on TWRP via Wipe -> Format Data?

just format data and install rom through micro sd if your internal storage not working in twrp

Alright. Im not that experienced with edl. Can you send picture of Wipe -> Advanced Wipe that we can see all of the partitions? Maybe also if you can send pictures of every partitions details by ticking them and then going to "Repair or Change File System" and taking screenshots? Don't know if this is gonna help, but it's worth a try.

Try changing the filesystem of /data to ext4, and then back to f2fs, and then rebooting into TWRP. I've had this problem before, and that worked for me.
