I am currently running CM12.1 on a 16gb version of Verizon GS3. I have less than 500MB (see attached screenshot) after updating from an older version of a JellyBeans ROM. I've gone through the normal steps to remove backup files, ROM files, clear cache, etc, but I still have low internal storage. What is the process wiping the internal memory in order to start with a "clean slate" and then re-install CM12.1? I want to make sure I don't do anything to brick my phone, so please be specific, I have some ROM flashing experience, but I'm not exactly a pro at this, so I need details or a video to help this dummy out. Thanks in advance!

Would I be correct in thinking you have CWM recovery installed? I am not actually familiar with the capabilities of recent CM recoveries, the last I used was for my 5 y/o SGS Captivate.
First have a copy of your nandroid or a fresh zip of the ROM on your external sdcard, have GAPPS here also. If CWM will permit, wipe /system and /data in addition to cache and dalvik cache. I have seen some refer to wiping /system as formating the internal sdcard. (I have seen others state that doing a factory reset with the stock recovery gives the cleanest device, but most needing this were going back to a TouchWiz based ROM after being on LP.)
You then reflash your ROM and GAPPS.
Hi there,
Just a small question: When I install a custom ROM, does it keep my data on the internal storage? I'm asking because of the encryption and I thought it could happen, that the new/custom ROM is not able to decrypt this part of the data.
Thanks
I haven't done enough flashing on my Pixel to say with certainty one way or another, but I believe it does keep the internal storage data between ROM flashes just fine. However, I don't fool with anything but PureNexus as far as custom ROMs, so it might depend on what ROM you're coming from and going to. I never flash anything major without backing up internal storage, anyway, and that's what I would suggest. After all, for every rule there's always an exception and it's better not to regret. Good luck!

You should stick to stock.
Well i am on stock i only wanted to know whether i have to backup my internal storage or not, when switching the ROM.
I wanted to update my rooted Android Nougat to Oreo and also go from SuperSU to Magisk. During that process I discovered that TWRP recovery couldn't mount my internal storage.
I quickly saw on a lot of sites that it's a well-known issue, and I solved it by converting from ext4 to ext2 and back again. Now my phone is running perfect. All apps are installed, data and settings are restored with Titanium and root with Magisk is working fine. But then I remembered about the issue with TWRP and booted into recovery - just to discover the problem is back again. I can't mount my internal storage. So I can't flash zip files, I can't do a backup etc.
When I search xda or the web in general, I can't figure out why the problem has occured again. Also I can't find out how to fix it without losing all my data. Can anybody answer these two questions? Why is this happening again and how do I permanently fix it? And can it be with all my data on my phone - because I'm not able to do a backup.

The problem occurs when you use a ROM which encrypts the software or the ROM your flashing has an encrypted kernal. The only way out is to flash a ROM which doesn't encrypt. It is a known problem with TWRP and we have to wait for the TWRP team to update TWRP to handle quota allocation.
It seems the problem is solved for me. I flashed the TWRP version from this link: https://forum.xda-developers.com/showpost.php?p=77296102&postcount=1243
First I tried from Odin but it didn't work. Then I installed the TWRP app from Google Play and flashed the other file, rebooted to recovery, and it seems to work. I can mount my internal storage, make a backup etc. So this is the solution for me.
I had also similar problem of internal storage 0mb and i was not be able to mount my data
so when i flash color recovery by nobody
It's gone because it's allready patch by him
I think it's issue of encrypt data so just flash this recovery from nobody post

Hey guys
wondering if somebody can assist me with my issue. I can mount the internal storage via twrp, and can copy files etc over to the internal storage on my pc. But when i go into file manager nothing appears. even though i indicate that it show me the internal storage. any ideas?

i think you must try with different file mngr, that one have no ability or permission to read system files

I'll re flash later and try a different file manager. Otherwise I'll install treble or re flash stock and start over

same problem, have you found solution ? please help me
TWRP sometimes can't mount the storage, the storage is encrypted, but don't worry. You can still flash your files and rewrite system partion. But in order to show the Storage, you have to use a different version of TWRP. Why am I saying this is mentioned following:
I installed the latest version of twrp, It didn't ask for any password patter to decrypt my storage. So , different XDA posts made me understand that , formatting everything, factory reset will decrypt my storage. And trust me, I have done it several time, several times my brother but it didn't decrypt my storage. I couldn't backup my ROM and without backing up my ROM, I didn't take the risk of flashing new ROM. I waited. This twrp couldn't even mount my system partion. So I seeked knowledge from different person. It took a lot of effort.
Then I learned that, I should change this version of TWRP. I changed to an older version and it didn't decrypt my internal storage after formatting, but it mounted my system partion. Since, it couldn't decrypt my internal storage, I couldn't take backup of my rom and save it to internal storage. so I inserted a pendrive in my phone, and saved the backup of my rom there.
Permanent Solution
Flashing DM Verity Force Encryption Disabler will decrypt your storage instantly. But in my case, it aroused another problem, None of the security measures of my phone worked afterwards. FOD, pin, password, pattern none of them worked. I don't know the reason but I don't suggest it with my little knowledge. but almost every rom flasher use them, so I thing I have to study about them to know how they work.
second and best option: start trying older version of TWRP, the good one will be the one to ask the password the recovery in the beginning. It will decrypt your internal storage.
I was brief here, if anyone doesn't understand these things, let me know, I will explain them step by step because I know the pain of being NEWB.
I need some explanation to make things clear..
1) First and most important. If you want to make a clean install, what you have to wipe? Should you format data also, and why? Format data affects system? Can you format data and still boot into rom? When you format/wipe all, is there something left in the phone? If no, then why still i can see in mount settings, that the folders still have Mb/Gb inside them? What are they? I guess you can';t delete everything from the phone? For example now i am stuck on custom animation bootloop. So there is still data left.
2) Format data make your encrypted or decrypted? Or just removes all encryption and if a) you install a rom you go automatically encrypted, b) you install a rom and flash no_verity you go decrypted?
3) If i go decrypted, the only way to go encypted is to install stock OS and why?
4) When is necessary to have the stock rom flashed in order to flash custom rom afterwards? If you want to install a different android version from the one that you have? Any other reason? Is it necessary to install the whole stock image, or just enough to install firmware + radio?
5) If you wipe/format all, the phone has some firmware,radio,vendor etc stored inside or it's empty 100%?
6) Is it 100% safe to install a TWRP through TWRP?
And now let's say the problem i had. But i think i know where was the problem.. I had installed android pie + xXx no_limits on my oneplus5 and i was decrypted. Some months later i decided to try something else, so i installed an AOSP android 10 version. I just wipe/format system,data,dalvik,cache then flashed rom, gapps, magisk. But i had some bugs on this version, lags and huge battery drain. Also whenever i was booting into TWRP it moved me on Mount --> Decrypt screen.. And i don't know why?
Now that i try to figure i know that the problem was i install a custom android 10 rom, without first installing the android 10 stock rom? In order to get the proper firmware etc? Or what? The instructions for installing the rom are the following, which i followed them 100% :
NOTE:
WE ARE ENCRYPTED (FILE BASED FORCED ENCRYPTION). So if you are unencrypted format data partition or use any no_verity solution you want. We don't support it.
1. Download the ROM and GApps and transfer them to your device.
2. Boot to recovery (TWRP recommended). Bluspark twrp recovery recommended.
3. Wipe the System, Cache, and Data (you might need to format the data partition in some cases!).
4. Flash firmware. Actual one is 9.0.11. Download.
5. Flash the ROM Zipfile.
6. Reboot to TWRP recovery.
7. Flash the GApps (optional, needed for e.g. Google Playstore to work) and Magisk (optional too if you want a root solution).
8. Reboot and set up your device.

The ROM should contain everything you need to enjoy Android Q. You don't need to install any Add-ons, simply download the latest ROM and GApps, then follow the flashing instructions and go!
If you want the device to run the ROM "rooted", you can flash a root solution of your choice after the ROM Zipfile.
It is STRONGLY recommended to fully wipe your device before flashing and please avoid restoring system apps and system data with Titanium Backup (or with any backup/restore app) as this can cause stability issues that are very hard to debug, restoring regular apps is fine though.

The only system app i restored was the Vanced youtube, but i don't this is the source of my problems.
Thanks in advance!
Guys i think i cleared some things on my mind..
When you install a rom you go encrypted. So you have to FORMAT data RIGHT AFTER installing the rom and then flashing no_verity? Am i right? When you format data do you lose Magisk also?

1) a clean install involves wiping system, data, cache and dalvik cache. All of these partitions must be wiped in order to remove data things that might conflict with the new software that you intend to flash. Yes, you can wipe data and still boot into your ROM. Yes, there are things still on the phone even after wiping the device, but, the things left behind are in partitions that are separate from what you can actually wipe, these other, separate partitions contain all the other stuff that is essential for your device to be able to function. These parts have nothing to do with the ROM that you are using and have nothing to do with what you have installed in your data partition. TWRP does not wipe /data/media partition(internal storage), /data/media is where your personal user data is stored, such as, photos, videos, downloaded files, data from apps such as games, etc. Basically, /data/media contains things that you have stored that are not apps. Your internal storage will still have all the files and folders that were there before you did the wipe. If you want to wipe internal storage, you have to specifically select your internal storage when you use TWRP to wipe the device, it will not wipe internal storage by default. If you still have a custom animation even after wiping the device, it is probably because the boot animation is in your system partition, that can only be removed by selecting the /system partition when using TWRP to wipe the device.
2) Formatting data "should" remove encryption. No, flashing a new ROM after removing encryption will not encrypt the device again unless you specifically choose to encrypt the device in its settings. Flashing no verity only eliminates issues involved with rooting a device and getting root to actually work without corrupting the device.
3)I'm not sure but I think you can encrypt a device without using stock.
4) It depends on which device you have, what your current firmware version is and what you are trying to flash. Some devices require a certain firmware to be installed before flashing certain custom ROMs but it is a case by case scenario. There is no specific answer to this, there is only the question of whether your specific device requires this or a question of whether the custom ROM that you are trying to flash requires this. This is best answered by reading the thread where the ROM is posted, if your device requires installing a certain stock firmware before flashing the custom ROM, it will tell you that somewhere in the thread for that ROM. Whether you need to install the entire firmware or just parts of the firmware also depends on which device you are using in some cases, you might only need the modem or only the bootloader or maybe both, or maybe none, or maybe the complete firmware.
5) As I stated above, there are partitions on the device that do not get wiped when using TWRP to wipe the device. If it wiped EVERYTHING, the device would no longer function at all, it wouldn't be able to power on, it wouldn't be able to boot into any of its modes and you wouldn't be able to flash anything at all on the device, not even it's original stock firmware. There are software elements that MUST remain on the device in order for it to continue to function.
6) It is perfectly safe to use your existing version of TWRP to flash another TWRP version, assuming the new TWRP is also built for your specific model number.
If you have installed a custom ROM and you are having issues, you need to go to the thread where you got the ROM and post your issues/questions there. The users there will know more about your device and what you actually need to do and the developer may also need to fix things in their ROM to solve the issues that you are experiencing.

I have ArrowOS 12 installed, with 11 the updates went well but now if I try to update i get the messages in the title. I tried to repair the filesystem, changed it from ext4 to ext2 and ext4 back again, wipe basically everything, can't restore anything, really have no idea of what I should do more.
TWRP is on 3.5.2_11.0, I have no personal files on the phone so anything is ok.

All custom recoveries (TWRP, OrangeFox) cannot decrypt Android 12 data in the meantime, so you will not see any internal storage and cannot mount.
If you want your data, you can try ArrowOS 11, restore data into ArrowOS 11, make sure data works in ArrowOS 11 system boot, then flash ArrowOS 12 without format data.
Some said you can do that, but there's chance it will fail, but since your phone has no personal files, you can try.
There is update of TWRP 3.6.0_11.0

Thanks man, does this mean there is no effective way to update the OS on android 12 in any way, no custom roms at least? In that case I'm very confused as to why the update button even is there

Custom recoveries cannot decrypt internal storage, but can read microSD cards and USB OTG. Remember Poco X3 Pro has microSD slot.
You can also use ADB sideload command in custom recoveries to flash zip files, so ROM updates can be installed this way.
Almost all function of custom recoveries are working, except decrypting internal storage.
