[Solved]Nexus won't boot after ROM and other things

Hello guys, I've searched a little and didn't find any posts that could help me specifically for the Galaxy Nexus.
I've flashed my phone a long time ago and have been using Paranoid Android for probably over a year.
The problem is, my cellphone was really really slow. So I decided to try a new ROM and re-flash it. And So I did.
I've tried flashing this Full_Auto R11 kernel then the CyanogenMod 12 and finally GAPPS.
I was getting error status 6 on Clockwork mod on gapps, but eventually got around it. But it didn't install play store, I've tried manually adding but it didn't work.
So I went for another 5.0 ROM (I'm really interested in getting android 5.0). Wiped all the data, all the cache, installed everything and rebooted.
Bam! Infinite booting screen.
No, I didn't create a nandroid backup because I'm really dumb.
So, I need your help. What I want to do is to get my phone working again with a 5.0 ROM (if possible).
I can boot into ClockWork Recovery just fine, if that helps.
Thank you for the attention.

I would recommend to install latest full factory package from Google.
Then you will start with everything stock, so flash latest TWRP recovery via fastboot (CWM is no longer supported, so error 6 when installing new Lollipop Google Apps appears).
Then in TWRP, do a factory reset, wipe /cache and /system partitions.
Then you can install your Lollipop ROM (over ADB or by pushing ROM package to emulated sdcard).
After this, install latest Full_Auto kernel.
At the end, install Pico Google Apps.
You must install the Pico version, because our /system parition is too small to handle Lollipop with all Google Apps included.
This should work for you, and you will have fully working Lollipop on your Galaxy Nexus
P.S: If you intall the AOSP Lollipop ROM by @freshgiammi and you miss root access, install latest SuperSU flashable zip.

Thank you!
Thank you man!
I've ran into some troubles but managed to do everythings correctly =)
This post can be locked up now.
Thanks again for the reply, LamarrCZ!!

[Need urgent help] Multiple issues on my Oneplus 3

I got my op3 phone loaded up with twrp version 3.0.2-1 but many errors occurred after I flashed this version.
Current problems on my phone right now:
-"The dm-verity is not started in enforcing mode" occurs every time I turn on the phone.
-Twrp won't read any of my files inside the "sdcard" folder wether it's just regular folder, .zip files, and even .img files.
-It also looks like only 1 version works of twrp works on my phone right now since any twrp versions after 3.1.0 causes the twrp program to froze and doesn't completely move past welcome screen of twrp.

I believe I had the same problem. Contact OnePlus on their support page. In a chat support window, tell the operater about your problem, and ask for an appointment with a level 2 technician. They should schedule you an appointment with a technician who should be able to wipe your phone no matter what state/condition it's in. They fixed my phone in a matter of minutes. But PLEASE, try to remember to be respectful and co-operative, it usually gets you better service no matter who you are dealing with.

For dm - verity problem, it's not a problem tough... Just a security breach as seen by Google.
BTW here is the fix...It's easy , follow the thread :
https://forum.xda-developers.com/oneplus-3/how-to/fix-easy-method-removing-dm-verity-t3544339
Can't comment on twrp as I'm on the 3.0.2-1, haven't tried 3.1. Hope it helps, Thanks!

Use TWRP 3.0.4-1. 3.0.2 can't decrypt internal storage, at least not on mine it couldn't.
Also if you have f2fs file system, TWRP takes a loooooong time to boot. Just wait, even though it seems hung. Takes several minutes. If you have ext4, it's quick. Use the app 'Diskinfo' to check

I had TWRP 3.1 and it would not do OTA of lineage, it would wipe the device when I tried and would not restore backed ROMs, stay away from TWRP 3.1. So, i went back to 3.0.4.1 via fastboot. My suggestion is flash the stock recovery from Oxygen 3.8 marshmallow (this can be found in the archived OnePlus 3 tool kit on XDA) and then sideload the stock marshmallow Oxygen 3.2.8 (download from OnePlus support page) and start all over.

That doesn't make sense..
The latest recovery works fine here, atleast the official one. If you are in F2fs and encrypted keep in mind it takes a long long time since F2fs is really bad at this.. Depending in how full your internal storage is it can take up to 10 minutesm

Twrp 3.0.4.1 or
3.1.0 x v.26 blu_spark.
To get OTA you need to be stock, only Oos official stuff.

I do have my oneplus 3 formatted as f2fs, but it is not encrypted. I don't know what happened to it when I tried to do an update with lineage os it basically factory reset the phone (and no I didn't wipe anything but the cache) and it would not install any zips from my internal sd card. I had to go back to fastboot and reflash TWRP 3.0.4.1 recovery. Then I wiped the device and reinstalled lineage, now it works perfectly fine.
They are lineage nighty OTA updates.

Phone bricks when trying to flash new ROM?!

I'm currently running my OP3 on Resurrection Remix 5.7.4 (MM 6.01), the phone has the latest version of TWRP and I've flashed other ROMs in the past without any issue
RR has proven to be quite unstable for me, the system UI keeps crashing, which renders the phone unusable until after a reboot so I wanted to flash Freedom OS as that worked quite well for me previously. When I tried to flash the ROM in TWRP the ROM seemed to flash successfully but when I rebooted, only the boot logo showed and then the screen went black and the phone refused to respond at all for about two hours, after that exactly the same thing happened. I managed to boot into recovery and tried flashing a different ROM but the result was the same every time, the only way to get the phone to work normally was to flash RR again/restore from a Nandroid backup, either way, the result is the same, I'm stuck on an unstable ROM and I don't know why, the last time I flashed these ROMs they worked fine, I followed all of the instructions for flashing said ROMs to the letter, I have the latest version of TWRP, etc.
Seems TWRP can't mount /system, in TWRP under "mount", system is unchecked, I checked it and tried again but found that whenever I rebooted the phone or attempted to flash a new ROM, it would always uncheck itself and flashing the ROM would fail, however strangely flashing the same version of RR was always successful. Does anyone know what the problem could be?

I would suggest you clean flash OOS first before going to Freedom.
I think RR is based on Lineage OS while Freedom is based on stock OOS.

RR is based on CM. I'm just scared to flash OOS in case it goes wrong because stock OOS will overwrite TWRP with its stock recovery and then I'll be screwed because I'll have no way to restore from a backup if it goes wrong

Yeah I thought it seemed a little out of place but I don't know where to post it? Is there a general questions forum?

I don't think that there is a risk in flashing stock OOS. But if the custom recovery is overwritten then flash it back, your backup files are stored in your internal memory and unless you wipe it you are safe.

Even when I tried flashing other CM based ROMs, including ones I'd flashed before, it failed, only flashing RR actually worked. I don't know why this is the case but I'm not sure flashing OOS without knowing what the issue is, is the solution because if I lose TWRP there's no telling whether I'll be able to flash it back in fastboot if the phone isn't working properly

I once flashed RR based on android 7.1.1 and because I did not like it very much I wanted to go back to Freedom but at that time it was based on android 7.0.1 thus I was unable to boot. Maybe you are facing the same issue. But in my case I hardbricked my device and used the unbricking tool from OP3 forum.
If you download the latest OOS zip file you can flash it through TWRP and you won't lose you custom recovery.

All of the ROMs I tried with were android 6.0.1, I'm avoiding touching android 7 because I'm not a fan
The strange thing is that in TWRP under "mount", system is unchecked and it won't stay checked when I reboot or try to flash something and then the flash fails. Strangely however, I can flash RR afresh and it will work but nothing else works
Therefore I don't think OOS would work either

Decrypting the phone and flashing new ROM

Last weekend, I decided to flash a new ROM since the one I have been using is no longer being developed. I flashed a LineageOS nightly build because I used to like Cyanogenmod and heard Lineage is a continuation. I do like the ROM overall, but for some reason it encrypted my phone during install. I did not want it to do this, it just did it without asking me (when I first got my phone, I remember I was having problems with it being encrypted, with my recovery and such).
Is there any way to reinstall LineageOS without it encrypting the phone? If not, how do I decrypt the phone again and get back to basically stock + root? I downloaded the most up-to-date stock 7.1.2 ROM from Google, and was going to just flash that, but it wouldn't let me in TWRP (said the zip was not valid). I also tried rolling back to an older backup (not LineageOS), but the phone never booted.
FYI - I use Linux Mint and have the latest adb/fastboot, and the latest TWRP for Nexus 5x.
Thank you if you can help.

If you want to flash stock rom you have to flash it via fastboot. The instruction is on the Google download side. But if I remember right you have to wipe everything so make a backup of important data.

If I format my "userdata" with fastboot to get rid of the encryption, do you know if it will delete my ROM backups? I think the encryption is why I'm having trouble going to another ROM from LineageOS. I REALLY wish the ROM would simply ask you before deciding to encrypt the phone. I have no reason to encrypt my phone, and I don't want it encrypted.

Encrypted/Decrypted

Someone please explain this to me. Idk if it's because I've been out of the rooted/custom rim game for so long or if I've gotten dumber in my old age. Also this is the first ohone I've ever had to even think about it with.
So I:
Boot into TWRP
wipe /data
Boot back into os
Profit?
Or boot back into TWRP
Flash dm-whatever the hell it's called
Boot into os
Profit?
Also, is any if this necessary at all just to flash a different rom? Being encrypted has no bearing on my life, so I don't care if I am or not.
EDIT: I'm currently going back thru old posts so I'll delete if I find my answer before there's a reply.

If you've installed TWRP you can just flash a custom ROM unless the ROM says something about "dm-verity required [disabled/enabled]". Disabled, means no encryption. Enabled is encrypted.
Any time you flash a different ROM you need to Factory Reset. Otherwise CustomROM 1.2 to 1.3 is usually safe to dirty flash (no data wipe).

Ok. Just making sure I wasn't screwing up by flashing like I normally would:
Wipe
Rom
Gapps
Root
Reboot
Verity if it says to in the OP of the rom thread.

How does this dm-verity business work? Whenever I try to flash a later OOS version without a "format" when it boots I always get the encryption failed message. Will flashing the dm-verity .zip fix that?
This phone is a real pain in the backside to flash with. TWRP backups usually fail, encryption issues and all that stuff. On my last phone it was flash and forget. What happened?

You only need to flash no-dm-verity if you want to run an unencrypted rom. All OOS ROMs are encrypted so of course you're going to get encryption failed. Omni has encryption and so does Liquid Remix now, so you don't need the verity file at all, unless you want to stay unencrypted on a ROM that supports it. Since you have been decrypted by flashing the verity file, if you want to go back to OOS, you will now need to format data (at the bottom right in wipe menu) in TWRP after flashing OOS. This will wipe all user data. DO NOT flash no-dm-verity again! If you think this phone's complicated, don't buy an Essential or any device with A/B partitions, it's a nightmare.
Edit: Actually I'm not sure if you can run OOS unencrypted or not (never tried), but if you want to restore factory encryption an flash back to stock, you have to restore the stock recovery. This guide by The Doctor will help you: https://forum.xda-developers.com/oneplus-5t/how-to/how-to-revert-to-oos-oreo-8-1-t3730952/page4
If you just want to run a custom ROM encrypted, formatting data in TWRP should work.
