I have TWRP and root, so from what I see, the data partition is encrypted and shouldn't be messed with. So are we still good to wipe system when we flash roms, or is dirty flashing the way to go, and is data the only "locked" partition if you will at the moment? Thanks

I know wipe out User data is must coming from Stock ROMs. I do flashing custom ROMs very frequently and wanted to know while flashing these custom ROMs, Wiping Data and Cache and Dalvik is what I do AND can I skip Wipe User data ?? Please help...
You will need to clean everything because you are going to avoid the bootloops.. and do it on every new installation does not matter if the rom is stock or custom
Thanks Mate!!
Hey guys, I unlocked the bootloader, flashed twrp and root. Then I proceeded to do a fastboot format userdata. But after the boot the encryption was still there. Now I am running PureNexus latest build along with ElementalX kernel. I would like to remove encryption when I will be flashing another rom, How do I do that? Do I simply need to do a fastboot format userdata? Will I lose Twrp and root if I do that?
If you format user data and then boot with the stock kernel it will just re encrypt the device.
Only way to stop this to format usersata and then BEFORE booting the device flashing a kernel or custom rom with force encrypt disabled.
Keep in mind the installation instructions that come with your custom ROM or kernel though. Some require you to be on stock before flashing.
I would generally consider dirty flashing a different ROM over purenexus a bad idea, so you best revert to stock, format user data to disable encryption, do a factory reset then install the new custom rom.
You will lose everything though and have to start from scratch. You may get away with using titanium backup for backup and restoring apps if you know what you are doing.
If the ROM has a kernel with force encrypt disabled then you just flash the whole ROM through fastboot and boot it. What ROM are going to try?
Someone told me on reddit to just simply format data using twrp and that it will remove the encryption and wipe my whole internal storage. Is that correct?
I believe it does just that.
Hey guys,
So last night I accidentally wiped internal storage in TWRP. I guess that messed up my partitions or something, I don't know. Anyway, I can still access recovery, and I've tried to do a restore (one that I made back when I was on stock 4.4.2 I think) but after that it tries to boot, gets to "Android is upgrading... Optimizing app Y of X." and once that operation completes it shows the lockscreen for about a tenth of a second, and the phone reboots.
I'm stumped. Anyone know what can I do?
Sorry if this has been asked a hundred times. For some reason the search function in the forums isn't working for me. And I've been looking for a solution all morning.
EDIT: FYI when I tried the restore I did only System and Data and not Boot, because I was afraid that'd cause more problems.
Did you try restoring and performing a factory wipe before booting the newly-restored ROM?
It seems that Marshmallow based roms aren't working, but Lollipop ones will boot. Not sure why as I didn't have any problem with the same MM roms in the past.
More info:
MM roms wont flash in TWRP; after the failed attempt, TWRP says system cannot be mounted until I either wipe or install a 12.1 rom.
Tried to install a stock rom (4.4.2) and it failed in TWRP. Just says "Error Flashing"
Are you performing a full wipe (system, Dalvik, cache, data) before installing or restoring a ROM? Is the phone running the latest version of TWRP?

Yes to full wipe. TWRP is 2.8.7.0, so yeah I think it's the newest? Not 100% sure.
Wiping internal storage should not affect the partitions. I'm not sure that TWRP even has the ability to change partitions.
Yes, 2.8.7.0 is the latester version of TWRP.
If you are on the nj2 bootloader, try flashing this in TWRP: http://forum.xda-developers.com/galaxy-s3-att/general/rooted-ucufnj1-stock-rom-t2985006
Welp, seems to be all good now. Not sure if I really did anything to fix it or not. I tried to install a stock ROM but it wouldn't boot (stuck on Samsung logo) but after that my CM13 ROM installed properly again. The one CM13 ROM I have still wont install at all - maybe that file became corrupt or something? Not sure if that's even possible.
Either way I'm all fixed up. Thanks for all your help.
Cheers
Glad you got it sorted out. If you do figure out what you did to get it working, post your answer as it may help others that are in a similar situation.
I'm having some issues flashing any ROM. TWRP will not wipe data, or internal SD
For some reason, when I go to wipe data and factory reset, TWRP will say it was successful, but nothing ever gets wiped. It will only wipe system if I choose to. I've gotten a ROM to flash but when it boots up, all of the old apps and user data are still there and it makes everything crash. I've gotten into settings to do a reset, it reboots into recovery, runs the script, and still nothing wipes.
What I have tried:
Old TWRP, newest TWRP
CWM (seems to wipe but it won't get past the note 2 screen after flashing anything)
Wiping with CWM, flashing TWRP, then flashing a ROM (still loops after the note 2 screen)
Is there a terminal command I can use in TWRP to manually wipe things?
Thanks for any help I can get, I've flashed so many phones I can't remember but I've never had this issue
Maybe flash back to a stock ROM, factory wipe using stock recovery, then flash TWRP?

Well when it bootloops t the Note 2 screen, I have to flash a ROM with Odin to get it working again. I've flashed a stock ROM with Odin, flashed TWRP with Odin, tried the wipes and it never wipes anything... I'm lost...
Isn't there a format function in TWRP that is seperate from the factory reset or advanced wipes? I was also trying to find a terminal command to type in the terminal in TWRP... I'm a little stumped...
I'm sorry, I read that too fast... That may actually work, wipe it in the stock recovery, and just don't let it boot into the system before flashing other stuff... I'm gonna try that out... Thanks man, I'll post back about it...
Since you are flashing the phone with Odin, is it a stock 4.1.1 ROM you're flashing? Which custom ROM are you flashing to the phone?

The stock ROM I used is I317-ODIN-UCUCNJ1-Stock without the booloader packaged in, I'm still on the old bootloader. It's 4.4.2
The ROMS I've tried to flash was
Cyanide (Error 7, says incompatible data, please wipe the phone)
Resurrection Remix (Error 7, says incompatible data, please wipe the phone)
Latest CM10 Nightly
I got CM10 and Resurrection Remix to flash a couple times, but the phone boots and all the old apps and data, including the AT&T ones are still there, and the system keeps crashing. Then I change the recovery to CWM because it seems to wipe, change back to TWRP, flash the ROM and gapps again, but it bootloops at the Note 2 screen.
Should I try the 4.1.1 ROM and CWM? Whenever I'm going from a stock TW to non-TW I like to format everything, data, cache, system, and internal SD, but of course TWRP won't wipe the data or the internal SD.
It's probably because the bootloader and modem are too old for the roms. Recent roms will need updated bootloaders.
Ok, I had some more time to mess around with this today and figured it out. I feel kind of dumb but oh well, I got it.
TWRP was already loaded on, so I went to messing with it again. The 'Swipe to factory reset' was not wiping the data, and there was the 'Format Data' button right there in front of me. I did the factory reset, format data, rebooted recovery, wiped dalvik, cache, and system, then flashed the ROM and everything booted up just fine.
Thanks for all of the help!
How do i install xiaomi.eu when coming from an AOSP custom rom?
I was using Paranoid Android Quartz 4 (AOSP) for a good while now but it i want to go to xiaomi.eu because of the better battery management and other features.
I wanna know what's the right procedure to flash the rom. I am going to include the rom and custom kernel plus magisk on top.
Im confused as to which to wipe and/or format. Like which to do first and such before flashing the rom, kernel and magisk.
I'm using OrangeFox recovery because TWRP doesnt work on mine. Phone is ginkgo.
Thanks for the response
Wipe dalvik, cache, system, vendor, data. Flash rom, magisk. Reboot. If you face bootloop (most probably) then format data partition. You'll be okay.

Should i format data partition before flashing rom or should i do it after i face bootloop?
Thanks for replying
Format after flashing ROM. Formatting before flashing will wipe out internal storage.
