[Q] how to flash roms without losing data n files?

Alright guys I feel very nooby asking this but this is my first device that doesn't have a sd slot. Is there a way to flash a Rom without deleting the download and titanium folders?
My steps prior to flashing are
Wipe data, cache, n dalvik
Flash Rom
Then wipe cache n dalvik again
But if I wipe data then the Rom zip would be deleted before I can flash it?
Please help me on this thanks!

Hi,
Make only wipe data/factory reset, wipe cache partition and wipe dalvik cache, tat's all then flash your rom and reboot.
Don't wipe anything related to sd card/ext sd card or internal storage so you keep all your files in your "sd card" intact.

This won't happen on your LG G2. Even when using CWM you can see it is looking for an external SD card in the command line when doing a Factory Reset. You're internal SD card is never touched.
When you flash a ROM just:
Factory Reset
Flash Rom
Obviously make a backup first if you're worried, and you may need to flash Gapps depending on the ROM you flash.

understood, thanks guys

TWRP won't remove encryption

Hello everyone,
I am running 3.0.2-2 on the SM-G935FD and for whatever reason TWRP won't wipe the encryption, thus I cant read the internal SD card. I am getting the " /data mount" error.
I have done the advanced wipe and cleared everything except the external SD, am I using the wrong TWRP? any ideas?

You must wipe data! Wipe it all internal storage!

I had same issue on G935F. Try advanced and format data in twrp. The option where you have to type yes. If not then flash stock recovery, factory reset and boot into download and flash twrp before booting into system to flash dm-verity zip.

...have you tried cursing/threatening/random acts of violence on inanimate objects? no? well BEFORE you do, advance wipe, wipe system/data/etc, reboot, or there are ways to reformat as ExFat with a PC too.

Flashed TWRP and a custom rom; cannot access internal storage... please help

Guys I am in need of help. I did not fully understand step 10 in TWRP installation guide and just skipped originally. I did notice I could not wipe anything but thought I would be fine so I just dirty flashed custom ROM assuming wipe would work afterwards and I can clean install after.
I am obviously stuck now with 0MB internal storage shown along with no access to phone since it says upon boot that verification has failed and that I need to reset my phone.
Now, I do have important photos/datas which are invaluable and thus do not want to lose... I did hear other guys restored their nandroid backup and were fine.
My question is, is there any way for me to access and back up my internal data somehow? I did hear something like flashing a stock firmware via Odin without the cache inside. Could someone confirm that this would work please? Would really appreciate a response. Thanks guys.
I did try this:
If you only want a bootable system partition or writable data in TWRP:
Download dm-verity and force encryption disabler.
Without exiting TWRP, transfer no-verity-opt-encrypt.zip to your device over MTP* and flash it using [Install] in TWRP.
But TWRP would not allow me to flash because it said it could not mount storage. I presume this is because I exited TWRP...
Please, any guidance would be much appreciated.

Do a wipe, system, data/ dalvic , and cache . Do NOT check internal storage and SD card...reflash your rom

Thanks for the reply but I cannot do that since the phone does not let me wipe from TWRP due to the encryption issues I believe.

Could this help:
"Only if you want internal storage or data to work in TWRP:
Go to [Wipe] -> [Format Data] (not advanced wipe) -> type "yes".
WARNING: This will wipe your internal storage, disable encryption, and factory reset your phone!
Go to [Reboot] -> [Recovery]."
or

Thanks man. I am aware of this but have not done so which is my problem haha. Does anyone know of this set PIN before flashing stock rom on ODIN please? I obviously cannot since I cannot boot to system but I do not want to make assumptions like before, go ahead and cause myself more stress...

Hold up, have you flashed SuperSU? That should be the only thing stopping you from being able to boot up. After flashing TWRP and a custom rom you need to install SuperSU to be able to boot.
Either try to flash SuperSU using TWRP built in ADB or buy an external sd card and flash from there. You don't need to disable encryption and in fact, that zip you tried to use actually wipes your internal storage anyway so don't try it again.

Twrp internal storage shows 0mb.

How to solve data encrypted on twrp and shows internal memory 0mb?I doesnt have any backup?My all data is on risk?
I am on twrp 3.1.1 official.My phone is redmi 3s prime.
Plzzz give its solution

ur partition is wiped i think
flash a fastboot rom and then put twrp again

i have the same issue. after a faulty app update through playstore, my phone kept a bootloop. I wanted to save my data via twrp, but just see sd card 0 mb. would really appriciate if someone can provide me some feedback.

Format data
In that case u want your internal storage size restored.
You have to format data(removes all data)
There is an option Under 'Wipe Menu' in twrp called 'format data'.

TWRP fail to mount internal storage

Recently I installed nitrogen os, everything work fine. the problem is when i boot into twrp, it only can mount system and cache. I cannot format data in twrp. I tried to install different version of twrp but the result is the same. Anyone know how to fix it?

This is known, it's some bug in the Oreo builds of some ROM. This method will wipe all your data, including your internal storage: Go to fastboot mode, and type in: fastboot format userdata, then wait for it after that you can flash any ROM again. Good luck :good:

Thx a lot
