Hi,
Coming from PureNexus, I wanted to give CM13 a try. Made a nandroid backup so none of my data is lost, and put that backup on pc. I installed CM13 which went fine. It stopped at the CM booting animation and did not go further, so I cleanflashed Purenexus to restore my backup later on. Now PureNexus won't boot either. I'm out of ideas to try, and I want to get my phone back up and running ASAP.
Can anyone help me with this issue?

When you clean flashed, did you also wipe system? If you did and you're still hung at boot, your best bet would be to flash the factory images via fastboot and start fresh.

Are you wiping properly (system, data, cache, dalvik cache) before installing a ROM? Are you making sure you flash the appropriate vendor image after flashing the ROM? When you made your backup which options did you check? And which options are you restoring?

When I try to wipe, it's only wiping cache for some reason. My backup consists of everything except cache.

What do you mean it's only wiping cache? Explain to me how you're doing the wipe. Also, when creating a backup (and restoring it) you should only be selecting system, data, boot, and vendor.
PS. You didn't answer my question about whether you're flashing the vendor after flashing the ROM. If you want help you need to answer the questions that are asked.

I'll keep that in mind. When I boot up TRWP, I wiped system, dalvik, data, internal storage and cache. After that I pushed CM13 through adb. That's where the problems started.
EDIT: I flashed the most recent vendor after I flashed the ROM.

Ok, you definitely don't need to wipe internal storage before flashing so don't worry about that part. Only system, data, cache, and dalvik cache. You said before only cache was being wiped, can you please elaborate on that?
Are you sure the ROM zip didn't become corrupt during the download? Did you check the MD5 to ensure that it didn't? That could be what's causing your problems. Also, what gapps are you flashing?
If you want to go back to Pure Nexus just to get your phone working you can just restore that backup, just make sure you only restore system, data, boot, and vendor.

It won't wipe anything other than cache, no matter what I'm trying to do. Now when I'm trying to push a ROM through adb, I can install it but it won't boot.

I'm trying to help you here but if you keep failing to answer my questions it's impossible for me to do so. At this point I can only think that it's user error, I'd flash the factory images to return to stock and start fresh. I have detailed instructions in my guide:

I found your guide by googling, thanks for making that! Flashing the factory image worked, and I succesfully restored my backup. The only problem left is that it won't accept my pattern lock. I have used the same one for years across multiple android devices, so I'm absolutely sure I have the right pattern. Any way to bypass this?

You need to remove all security before making a backup because the security information is encrypted and doesn't get backed up or restored properly. You can delete some files using TWRP (see section 3 of my guide) in order to remove the security so you can get into Android. This will cause problems with Smart Lock though.

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.

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

No you want to go to format and ask you to type yes. Do this. Then flash the ROM you want. Fulmics, stock, etc.
Ok doing that
Fulmics installed correctly but it still asks me to enter a password in twrp

Do the following:
1. Put Fulmics rom or any other rom on the SD Card and put it in your phone.
2. Format your system, don't wipe because your phone needs to be configured again.
3. Install TWRP on your phone with ADB.
4. Install the Fulmics rom.
5. Now it should be all okay.
TWRP is working properly now I can now make backups with TWRP, thanks
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.

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!

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
I was using PE rom and I flashed a kernel and wiped cache and dalvik, after rebooting i couldn't turn on my mobile data for some reason. I went back to orange fox recovery and wiped system, cache, data, dalvik, vendor. Then i tried rebooting but it says no os installed. I used my other phone to download the latest PE rom and saved it on my sd card so i can flash it on my phone. I wiped cache, data, system, dalvik and vendor again before flashing the PE rom. After i flashed the rom im stuck on the boot image of PE i dont know why. Anyone knows how to fix this?
Is bc i wiped my phone's firmware too and thats the reason why my phone wont boot completely?

OMG!
1. You should never wipe system or vendor.
2. You should never wipe the firmware. Why on earth would you want to do that?
3. Format the data partition; reboot the recovery; flash a working firmware image (if you did indeed wipe the firmware); flash PE; hope for the best
