CM12 - black screen after enter my PIN :(

I have a weird issue with my N9005 (hlte). I just got it new and am still a little inexperienced with flashing it. Preblem occurs when flashing ANY CM12 based rom. Flashing works well with TWRP 2.8.5.0 but once Android booted just after enetring my PIN the display turns off and I can't do anything and have to hard reboot my phone. CM11 runs without any issues
I'd relly like to go for CM12 so any help will be appreciated.

Did you wipe data and cache? After installation

I performed a full wipe before flashing. Any advantages wiping again, once flashed?

If you read installation instructions from temasek it says clear dalvik and cache. For good measure. No full wipe after flash. Only cache and dalvik

If i full wipe my phone after flashing ... i got no System at all ...
It looks like -> this <-

Haha I did correct myself and told you to not full wipe after flash. Only do that before flashing. Wipe dalvik cache and cache after flashing.
Do a clean install and try again. Full system, data wipe and caches in recovery. Use twrp doing that. Then flash and wipe cache and dalvik. Reboot. Use the latest build 8.7

encryption password on boot

on my A2017U After unlocking the bootloader and having twrp 3.0.4 installed I went to install resurrection remix and gapps and upon boot it asks for a password that I had never set up. before installing the ROM i formatted the data and wiped everything. What do I need to do? I reloaded a stock rom and in the settings it says the phone is encrypted. I've tried searching for answers to this but I haven't been able to find anything..

Go to TWRP - Wipe - Format data - write 'yes'

...and maybe update TWRP.

I flashed it again, formatting data before flashing everything, still came up with the dialog to inter password. I rebooted into twrp and formatted data again, reboot, still asks for password

updating TWRP to latest build and I still have the same issue

If you Install another ROM, after wiping everything, is this problem still there?

Delete locksettings.db?

Are you sure you are ACTUALLY USING the 'Format data' button? Wiping won't do anything to the encryption (i'm asking just to be sure).
Otherwise try doing this:
-Format data, wipe system, dalvik, cache
-Flash Universal Bstck
-Flash your modem
-Flash the ROM
-Flash either noverity-opt-encrypt-axon7 (I think the name was that one; just make sure it is for the axon7 or ailsa_ii), or SuperSU/Magisk which should have that packaged in.
This really shouldn't happen...

yes, I am actually using format data button and typing yes. I will try using the noverity later this evening and give you a followup

If I remember this right you have to use both in twrp,
factory reset and format data, I read this here on XDA or Reddit before I unlocked my bootloader.

this is what I did.
1. Boot to TWRP
2. wipe/factory reset
3. advanced wipe everything but sd card and usb
4. format data, type yes
5. install ROM and Gapps
6. boot.
everything loads okay except I get it asking for password
I have not tried another ROM yet or the noverity-opt-encrypt-axon7 I will have to do those later tonight.
One more thing I was going to try is remove the lockscreen pin/fingerprint on the stock before doing anything

Do this after you flashed rom and gapps, only factory reset and format data, no need to wipe other stuff.
Edit: I did this directly after the unlock, I flashed the latest official twrp through the unlock twrp version, rebooted to twrp, advanced wiped caches and data, not system, flashed bootloader and modem from the Los thread for my axon version, flashed dark rom with gapps, rebooted and run into the same issue as you. Back to twrp, factory reset, format data, then reboot and everything was good ....., Or Format data and then factory reset, try both if necessary.

Another thing you could try is booting to the bootloader and trying "fastboot format userdata"

You just need to wipe data cache dalvic after flashing the ROM

You have the factory reset step in the wrong place. Do it after the rom and gapps installation...
Essentially the phone is still encrypted though factory reset . You need to get rid of the encryption AFTER you flash the new ROM...

Change the data file system to ext4.

This did the trick.
Flashed bootloader, modem, rom, gapps. factory reset and format data. boot to password, reboot to twrp, factory reset, format data, reboot to working rom no password. Thank you and to everyone else for your help!

This seemed to do the trick for me.
To change the file system type in TWRP 3.2.3.0:
Go to 'wipe', then 'advanced wipe' and select 'Data', press 'Repair or Change File System' and then 'Change File System' to EXT4. It will say "format" which often means "delete" but didn't remove the ROM I had flashed moments before.
I also did this below first- but without doing a re-flash of the bootloader and modem:

Idk if this will help with your use case, but for other users, it can be good to know.
but for the stock ROM: Settings -> Security -> Screen Lock -> Enter your pin -> It should ask you if you want to shut off the password on boot up

Random names TWRP

Hi, I'm from Nougat 4.5.14 and these are the steps I made:
1. Flash codeworx then reboot to twrp
2. Wipe cache and dalvik
3. Install OS 5.0.2
4. Install magisk
5. Wipe cache dalvik
6. Reboot to system
However after rebooting to system it started bootlooping so I decided to reflash OS and wipe data as recommended. So I power off the phone then hold volume down + power to boot to recovery. However when I boot to recovery, file folders started to become random names like its encrypted. Luckily I backed up my internal storage and data so I'm okay to flash everything but can someone help me how to fix the twrp random file names and the steps for reflashing the OS?
EDIT: I rebooted to recovery, wiped dalvik, cache, and data. flashed OS 5.0.2, wipe dalvik cache, flashed magisk, wipe dalvik, reboot to system and it does not proceed to circling dots. So what I did is just, wipe dalvik, cache, data, flashed OS, wipe again dalvik cache, boot to system and it proceeds to circling dots however it takes so long that I can consider this as bootloop. I'm very tempted to wipe everything (data, system, internal storage, cache, dalvik) then just flash again the OS but I don't know if it would work so I hope someone could give me some steps how to fix this
Edit 2: This is solved now: What I did is just after trying the flash OS with no magisk, I booted to system. However, i just dont boot at all so I decided to boot to recovery again, but this time the recovery is the stock one. I wipe everything I could including cache, system reset, and data (music pics etc) and it booted to the system in no time but everythings lost.

You have to format data... Not just wipe it. From TWRP go to format data, write yes, and let it format everything. Then transfer over to the phone all the fil a you need (ROM, kernel, no verity zip) and flash them as per the instructions of your rom thread. You should be fine.

From AOSP to miui

Hi,
Running latest evolution x rom and want to go back to miui. Simply wiped everything in twrp and installed xiaomi.eu rom - installation was successfully but when It's finish booting and the set-up screen should be there my screen just goes black and set-up screen is coming again and again and again and again. Even tried different miui ROMs. Was running completely fine a week before.
Any suggestions?

Did you leave your password/pin before you changed rom? Try deleting in TWRP and see if it helps.

Sorry but I'm out of ideas then. I usually go back and forth xiaomi.eu and aosp but I haven't encountered this. I usually wipe cache, dalvik, data, and system. I also have to reboot to recovery after wipe before flashing xiaomi.eu to be able to mount the system partition.

Mhm. I will try again this evening. Let's see.

I'm facing the same issue...
Coming from LOS, I flashed latest EU rom, wiped data and internal storage.
Now I'm looping at the setup screen "Just a sec..."
I removed the pin/pwd in TWRP but it didn't help

Oh sorry I misunderstood, no I just wiped /data.
As soon as I copied the rom on my phone again I'll try that if I'm facing the same issue :good:

I followed this steps to come back to MIUI from LOS:
1. Wiped everything (cache, internal, vendor, system, data)
2.After wiping I did "format data" and said "Yes"
3.Rebooted to recovery TWRP again
4.Mounted my phone on PC and copied rom.zip
5.Flashed the zip and reboot to system
Try this and it should work, for me did! Good luck!

Oh boi. So when I wipe my internal storage it's not the same like formating data ? This was my mistake

I don't know precisely why, but yeah, it's not the same thing. In fact, I had problems too, but formatting data after total wipe resolved them

formatting data "Yes" is another thing that is important when you flash custom ROM or go back to stock ROM.

After flash the miui, go back wipe -> Factory Data -> Type (yes) -> restart
it will be works

Same here
I flashed fastboot rom to get device work again

Phone boots into recovery after flashing an OTA

Hi,
I have been using Derpfest on my Redmi Note 6 Pro for a long time. To flash the latest version, I wiped cache, dalvik cache and data (as per their instructions) and then flashed the full zip. For some reason, the phone does not boot anymore, it goes into Mi logo, reboots, and then boots into recovery.
I have tried clearing data, dalvik, cache, system and internal storage and then flashing two different custom ROMs (Derpfest and HavocOS) but it still does not work.
Can someone please help me recover my phone?
Thanks

Flash the last miui rom. Recovery Edition. https://c.mi.com/thread-2959490-1-0.html?t=1585141449432&utm_source=share
Boot up and than install the rom you want.

The latest Derpfest uses a new kind of encryption (FBE). This requires formatting data if you were on an earlier version (or any other ROM) with FDE. This really should have been stated clearly in the Derpfest instructions and changelog (perhaps it was - I don't know). If you were using OrangeFox Recovery, you might have seen something (in red) about Android Rescue Party, advising clean-flashing the ROM.
