You don't need to flash it. If you don't know what it's for then don't flash it. Ignore any guides that tell you to flash it.
Basically dm-verity checks the integrity of the data in various partitions.
Any changes in the recovery partition cause the system to restore the default recovery.
It is also the reason why TWRP backups now have options to back-up system and vendor partitions as partition images, rather than just the data in them.
This TWRP article about backups briefly talks about dm-verity https://twrp.me/faq/whattobackup.html
Everything works fine with dm-verity still enabled on any ROM, custom or official.

Nexus 6 MRA58K/N/R Forced Encryption

I am sure this is a noob question here so I apologize in advance. I am a bit confused about how to go about disabling / removing encryption on my Nexus 6. When I look into it, it seems to be required to flash a new boot.img. However, you already need to use a modified boot.img to root.
So, once you are rooted, you can change your boot.img without losing root?
Does the modified boot.img from Chainfires post already disable / remove encryption?
Is there a modified boot image that disables encryption and allows root?
When I am in Titanium Backup, I see encryption: DISABLED. Is that telling me that my phone encryption is disabled or that just Titanium Backup Encryption is disabled?
Also, now there is MRA58K/N/R. Chainfires post has the modified boot image from K. Has the boot.img changed at all from K to N to R? If so, how can one still use the modified boot.img from K after flashing to R?
1. you need to flash a modified kernel(boot.img) that allows for decryption.
2. secondly, you have to format your user data and cache, which will delete everything from your phones storage.
3. now when you boot up, you will be decrypted.

I understand this. What I am wondering though, if this will remove root being you have to flash a modified boot image to obtain root. This is why I am confused. Does the modified boot image from chainfire for rooting the Nexus 6 remove encryption? I see where it may disable forced encryption, but does that mean that it removes encryption as well? Here is the post:
http://forum.xda-developers.com/apps/supersu/wip-android-6-0-marshmellow-t3219344
Sorry if I sound straight noob. I just don't get it. If I follow the root method which already requires a modified boot.img, how can I turn around and then flash yet another modified boot.img to remove encryption? Or does the modified boot.img for root also remove encryption?

you can flash different kernels all day long, and youll never lose root. only if you flash a rom will you lode root. about chainfires kernel i am clueless.

Do you have a Nexus 6? The current root method required a modified boot.img. So are you saying that after you flash the modified boot.img and obtain root, you then can change the boot.img and still have root?
Anyone else care to answer this for me? I am newer to Android period so I apologize again for sounding noob. I just don't fully quite understand how this root method works. So if a modified boot.img is required for root, how can I turn around and flash a different boot.img and still have root?
I am literally sitting here waiting to flash my Nexus 6 to MRA58R until I figure this out. I am well aware how to flash stock images, custom recovery, sideload superSU. I just want to clean flash my Nexus 6, have root, and have encryption disabled.

i use despair kernel. technically, any custom kernel is a modified kernel. and it alows for decryption, even though i did not decrypt. i flashed marshmallow, flashed despair, then flashed supersu. now im on marshmallow with root.
what im saying is that i have never used chainfires kernel, so dont know anything about it.
I have been googling my a$$ off and still can not find an answer. All I wan't to know, is that after I obtain root on my Nexus 6, which requires a modified boot.img, can I turn around a flash a different boot.img, and still have root. I want my Nexus 6 to be rooted and not use encryption. That is all I wan't. I can not believe I am having this hard of a time figuring this out.
Everything I find even closely related to this is about 5.0 / 5.1. I am new to Android, my Nexus 6 is my first Android device and all I know is 6.0 Marshmallow. I believe the root methods for 6.0 are different than 5.0/5.1 but I could be wrong. I prefer direct answers. No where can I find a definite answer.

first off, to make things easier, a boot.img is a kernel. you can flash any custom kernel when rooting on marshmallow, not just chainfires. if it doesnt allow unencryption, then you cam flash any other custom m kernel. you dont lose any information/data when flaahing kernels, so you never have to reroot. theres nothing hard here to understand, you can download and flash any kernel that you want, that will work on m. which one you chose is your choice. the vast amount of custom kernels allow for decryption.

Ok lets leave encryption out of it a second. So lets say I have stock 6.0. I flash the modified boot image, sideload SuperSU, and I am now rooted. Then I turn around and flash the stock boot.img. SO I will still have root then?

Ok I think I am starting to get it now. So the modified boot image that is needed to obtain root, is only initially needed to initially obtain root. Once root is obtain, you can flash different boot.img's all day long and you will not lose root? I understand boot.img is the kernal?

yes.
but the thing i dont know about is that the stock marshmallow kernel might prevent root, even though the files are still there. but you can flash any marshmallow custom kernel(for n6).
I figured it out. Here is what I ended up doing. I hope it was the best way to do so. I probably went overboard with some stuff but I wanted to start fresh from stock.
Booted into TWRP Recovery and did a full wipe 3 times over
Rebooted to bootloader
Flashed bone stock MRA58R
Rebooted to bootloader
Flashed modified boot.img, reboot bootloader
Flashed TWRP Recovery, reboot into recovery
Format Data, disabling encryption
Installed SuperSU, Wiped Dalvik Cache / Cache
Reboot System
I am now running Android 6.0 MRA58R / Rooted / No Encryption
I did not realize that encryption could be disabled right in TWRP. So that is why I was so confused because I thought I had to flash a modified boot.img to obtain root (which you do), then a different modified boot.img for encryption removal. If that was the case, I was worried that flashing the modified boot.img for encryption removal would remove root. Oh well. I have it figured out now.
Thank you for your help @simms22. You have given me a better understanding of root access and kernals.

I was trying to figure out the same thing. What modified boot.img did u use for root access and which modified boot.img did u use to remove encryption. Thanks.
Basically any kernel that does not check encryption and force it to be applied... In other words almost any 3rd party kernel... But double check the kernels feature list and make sure it says no forced encryption.
The device will probably give you a "system is corrupt" error with a stock kernel and root installed. I would flash a custom kernel for sure because it usually doesn't force encryption and does support root! I am using elementalx right now and it's a very good kernel for this. Many other custom kernels work just as well! I HAVE used chainfire's kernel, and it does not force encryption, it also supports root, I can confirm this. If you use chainfire's kernel, make sure you format your data to unencrypt. You can use the "format data" option in TWRP or use the fastboot command "fastboot format userdata". Hope I helped!
EDIT: You have to format your data to decrypt regardless of WHICH kernel you choose, sorry if that sounded confusing.

[Help][NOOB] Want to do fresh install of latest official OOS and stock recovery

Hello,
I have Oneplus 3 A3000 running on OOS 4.0.1 (Android 7.0). I also have official OP3 twrp recovery version 3.0.3-0 installed and root was done using supersu free v2.82.. It also has dm verity prompt which comes up during boot time because it is oem unlocked.
I want to know exact procedure to go to complete stock rom + stock recovery along with links to download stock recovery and rom. I saw different versions of stock recovery for different OOS. I don't care about device data as everything is on cloud and nothing on is on device. App list also I can get from google account history. Only thing I care is not to corrupt any system partitions. I also saw few posts that go into boot loop if incorrectly unrooted. I would not want that either.
Your help is greatly appreciated. Virtual beer for you ???. I am software engineer so even though I am noob in terms of hacking my android, I can follow the instructions properly.
Thanks again.
You can flash official OOS Rom and just use TWRP, you can try using the current recovery you have. Allow it to boot after if it allows you then do not go back to TWRP, allow it to boot to its system and then normally it will just override TWRP with OOS stock recovery.

I actually want to go to systemless su + magisk + xposed later on. This one didn't work well with some apps that can detect root. But before I do that I want to start fresh because things tend to go messy and i do not have a backup device right now

flash stock oos thats it.. you may leave the bootloader unlocked. better that way..
Sorry but I am still not sure about exact process. Here are my noob queries:
1. Should I update twrp to latest version before proceding? If so which one? currently it is 3.0.3-0. I remember running into encryption issue due to unsupported twrp when I did this last time.
2. Should I use wipe option to wipe anything before I update OOS? I want to do clean install. If so, what should I be wiping out of dalvik/system/data/internal storage/cache/usb otg?
3. To update, I should copy full ota zip on internal memory -> go to recovery -> install -> select zip file -> swipe to flash. Is that correct?
4. After that if I boot into recovery -> I will keep twrp and if I let it boot, it will replace twrp with stock recovery right?
5. Let say, I let it boot n install stock recovery, will I have dm-verity during next boot?
6. Will my superSU root be gone or still be there? If it is still there should I do complete unroot before starting this process?
7. If it is not gone, is it ok to do complete unroot after stock oos + recovery is installed?
8. I saw a dm-verity patch zip which can be used to patch dm-verity in bootloader mode if I do "fastboot oem disable_dm_verity and fastboot oem enable_dm_verity". Does it suppress the issue or it resolves it gracefully?
Thanks for the patience and help in answering the queries advance.

1. Try the first the current TWRP that you have. If it work, then just reboot it on to the system and TWRP will be overwritten by Stock OOS recovery.
2. Wipe dalvik/system/data/cache ..
3. YES , if im not mistaken.
4. answered on question 1.
5. most probably. Try flashing a certain firmware (not sure which one would work) . This is what I did before. But cant be sure.
6. It will be gone.
7. gone.
8. You can try.

I will tell you what I do.
Flash the latest official TWRP which is 3.1.1-2
If you want a totally clean install, boot into recovery and wipe system data including internal storage, dalvik and cache.
Then without rebooting, push the ROM downloaded from the OnePlus site to the phone. Select the ROM in recovery and swipe to flash.
Otherwise you can copy the ROM to the phone, boot into recovery, wipe system, data, dalvik and cache and then in recovery, flash the ROM.
Wipe dalvik and cache and reboot into system.
Your root will be gone and along with it TWRP. You will be on stock ROM with stock recovery.
Leave the bootloader unlocked. If necessary, it can be locked at any time.
Most likely you will not get the dm verity error. If you do, simply flash the zip given in post #215 in siankatabg's thread on dm verity. It will merely remove the message as all such methods do.
Enjoy

Hi sorry I was afk for couple of weeks. So I started following this procedure. Very strangely, after I did a reboot post stock OOS (1.4gb zip) flash, twrp said no os installed, you are sure you want to reboot? I wasn't sure so I just said yes. Then I also so dm-verity coming back which was not the case when I started as I had disabled it using "fastboot enable_dm_verity" command.
Now, its been more than five minutes and my phone is stuck on the boot animation forever. (red dot in middle and two while dots rotating).
I am not sure what happened. Can someone please help me ?

Awesome. I am still getting safety net failure even after locking bootloader lock. Any ideas? It fails on CTS profile match. I even did factory reset. Only thing I can think of is the "dm verity" which is back for some reason even though I am on complete stock rom+recovery with no root or unlocked bootloader.
Any way to remove it from stock recovery?

There is a zip floating around XDA which I am not able to locate immediately. It may be on siankatabg's thread on dm verity. Simply flash it.
There is also another method I read about where you flash the 4.0.2 firmware, use the enable verity command on adb, boot the phone and then flash the current firmware.
Both methods are mentioned here in XDA. Search for it.
EDIT: One of them here: https://forum.xda-developers.com/showpost.php?p=72273041&postcount=215
See also the OP of the same thread for the other method.

i remember having the dm verity but i forgot what i did to make it disappear.. after that time ive been running OOS rooted with twrp until i decided to go back to stock locked
So, I stopped doing anything as I got busy with my life. Here comes the 4.1.7 OTA and my DM verity was gone. So, it seems like if you go to stock and if still dm verity exists, try to do ota update or go to one ota back for flashing.

[ROM][US997][Stock] LG-US997 20A ROM - FILES UP NOW

In westwood24 style, I decided to create a flashable zip for us. We do not have a kdz yet, so westwood24 is unable to create the zip yet, as he no longer owns the device.
However, since I do, I decided to do system dumps of the updated images, and provide them to you in a flashable format, in his fashion.
I have tested this on my own device (US997v17a KDZ -> TWRP -> This ZIP)
What this means is that you can flash this like you would his zips, its not an upgrade, its a full ROM, with bootloader and everything.
It is the closest we are going to get to a KDZ, until we actually get one.
The boot.img is prepatched to remove rtcd, and disable forceencrypt, and also disables LG anti-custom-recovery script, so that you can keep TWRP, and mount your data in it.
This is NOT Melina kernel, this is stock kernel with the above patches applied only. If you would like Melina kernel, you will have to install it afterwards (but remember to reboot recovery first, see note in TWRP thread about writing boot more than once in a session)
Download [ My Server | Mega ]
For those who want 100% stock, here is an unpatched boot.img. Flash it in TWRP, or extract it and flash in fastboot.
But be aware what this means for /data and TWRP.
PAQ (Probably [going to be] Asked Questions):
Q: Can I flash this over v17a without wiping data?
A: In theory, yes. Untested. Be sure to wipe Dalvik Cache.
Q: Can I flash this over v16a or eariler without wiping data?
A: Probably not. Try it? Be sure to wipe Dalvik Cache.
Q: Can I flash this over (Fulmics/Lineage/RR/etc) without wiping data?
A: No.
Q: Does this include the new Oreo bootloader?
A: Yes.
Q: What does "forceencrypt" mean?
A: It means every time you boot, if you tried to format /data in recovery and unencrypted it, it gets re-encrypted. Disabling this allows you to have an unencrypted /data so that you can continue to use TWRP without losing /data.
Q: I can't sideload this zip, but I can sideload westwood24's. What gives?
A: No idea and I wish I knew. Copy it to your SDCard or Internal Data for now.
Q: I'm stuck at the bootloader. Did I brick?
A: No. First boot will take a while at the bootloader. Please give it up to 15 minutes.
Q: LG G6 ThinQ?
A: https://www.xda-developers.com/lg-g6-thinq-rebranding/
Q: I cannot mount data in TWRP. What can I do?
A: You need to use Melina TWRP rel_o1 or newer.
Special thanks go out to westwood24.
If my releases help you, please leave a thanks. If you are able, please consider a tip (check the small link in my sig).
Thanks! Looking forward to this.
I'm assuming that i need to have my bootloader unlocked in order to use this zip.

Yes, same as westwood24's zips.
I apologize for my ignorance, this does not preserve the already installed TWRP, correct? We need to reinstall TWRP and root in the same fashion we previously did?
Thanks for your support.
Just checked westwood24 posts and found my answer there in his installation instruction.
Thanks for this! I did a full wipe coming from 17a and it worked flawlessly using your oreo TWRP. Used Magisk 16.4 beta for root.

I don't usually flash modded kennels, but I'm interested in trying yours. Does it support magisk and Oreo?
Installing this tried to install the oreo system, but failed because of encryption. But some parts already has been changed. Booting was hanging on LG logo.
So I tried to install back my old version. Did also replace some parts, but after booting it told me the encryption key was correct but some data modified. The only possibility was to wipe everything

Downgrading from LG Oreo encryption to LG Nougat encryption will force you to wipe data.
If you don't care about encryption, wipe data in TWRP to decrypt, then reboot recovery, then install this zip.
If you do want encryption, flash this zip, reboot recovery, flash the unmodified boot, reboot system (will wipe root and twrp)

So I'm assuming Encryption works the same way on Oreo as it does on Nougat?
On Nougat, after the bootloader is unlocked (or twrp flashed or one of these steps), the option to encrypt is gone from the Fingerprints and Security settings menu. Only the "Encrypt SD Card" option remains.
So this means no chance for encryption on Oreo with root + twrp?

Encryption option remains. But no, encrypting will break /data in TWRP. Root may work if you root before you encrypt.
We cannot decrypt LG's data with TWRP yet.

Unfortunately since the US Cellular version can't be rooted because the bootloader isn't able to be unlocked we can't use this method we would have to wait until someone is able to create a kdz to flash.

We can't create KDZ, we wait for LG to release them.

Any way of knowing how long that might take?
Attempted OS upgrade from TWRP = SUCCESS
was running 17A(twrp) installed from twrp 20a(twrp), wiped dalvik and rebooted. No issues on upgrade
Worked great, Thanks!

Yeah I thought all the others were quicker than this on the nougat update, also the other models have kdz out for Oreo.
Anyone else having trouble with the Assistant?

How to reset firmware

so i've tried a few roms, and couldn't get gpay working. im going to try a few things mentioned in other threads, but before i start that. i want to properly/fully reset my phone to the stock, to hopefully make sure i don't mess anything up in the future.
my first issue was installing twrp, i tried to `fastboot flash` the recovery, but nothing worked until i followed these steps: https://www.getdroidtips.com/download-and-install-twrp-recovery-for-redmi-k20-pro-latest/
im worried about what might be in the misc.bin in that zip. cuz i couldn't reboot into twrp recovery until i flashed that. does anyone know what that is? i think i just want to flash/reset? everything on my phone back to miui, make sure i update to the latest firmware etc. but, tbh, i find navigating xda difficult and can't seem to find the official firmware anywhere, or steps on how to reset the phone...
thanks for any help
Um, i think ur in the wrong category

The misc.bin file is basically just a script that tells the Device to directly boot into TWRP, because Xiaomi Devices / MIUI are configured to overwrite TWRP after a reboot. If you still feel uncomfortable having to flash the misc file, try "fastboot *BOOT* TWRP.img" instead of "fastboot *FLASH* TWRP.img".
If you wish to keep MIUI installed instead of an Custom ROM make sure to flash Magisk, as it patches the DM-Verity stuff that causes the Device to either get stuck in a Bootloop or replace TWRP with the Stock Recovery.
If you're planning to run an Custom ROM like LineageOS, AOSiP etc. you don't have to flash Magisk as long as your Device isn't encrypted. Rebooting from TWRP to System without flashing Magisk on an encrypted Device will encrypt your Data Partition and you'll have to format Data to be able to access the Internal Storage again. (Flashing Magisk in that case will prevent your Device from encrypting all your Data again after an ROM Flash.)

k thanks for the info. what's the difference b/w the boot v flash for twrp?
is the misc.bin from that link i posted safe then? where did it come from? is there a thread here where files like that are posted/talked about?
i definitely plan to stick with either lineage or Pixel experience. i just want to get google pay going. so i think my next attempt will be to relflash magisk and look into that sql fix everyone mentions

If you're planning to go back to stock MIUI and locked bootloader, I highly recommend using Mi Flash and flashing the original fastboot MIUI ROM which can be found here https://www.xda-developers.com/download-miui-11-xiaomi-redmi-note-7-pro-poco-f1/amp/. All you gotta to do is extract the ROM file which is .tgz to any folder, and in Mi Flash select that folder click on "clean all and lock" in the bottom right corner, and click flash. This should theoretically make your device "out of the box".
Keep in mind that this method requires a PC with all ADB and fastboot drivers, they can be downloaded from here https://forum.xda-developers.com/showthread.php?t=2588979 .

BOOT will just let the Device temporarily boot into the Recovery (without making changes to the Recovery Partition) FLASH will write the Recovery Image to the Recovery Partition so you can boot to it whenever you want / need to.
I don't know if there's any kind of threads where certain files are talked about sorry, but I could be wrong though.
I don't know much about G Pay, I was gonna try it too but my Bank doesn't support it. I've seen quite a few people reporting success in getting it to work / making payments with it in local stores with the mentioned SQL Fix so if you're lucky it'll work for you too

Bootloop to twrp

Hello, I have flashed twrp, made a backup and tried to flash arrow os on my xiaomi mi 9t pro. However, now I'm stuck and it's just booting to twrp automatically. I've tried restoring boot, system, vendor, but no success. Does anyone know what to do? Also, how do I figure out which vendor I have, I didn't look previously and now it's not booting (so I could try to flash the original rom).

You probably needed to Format (not just Wipe) Data.
This is a MUST whenever you flash custom ROMs - something that everyone must read/learn about before going for custom ROMs
However, if you messed up your vendor or other partitions, you will probably need to flash the full tgz/fastboot firmware - Google is your friend

Google is not your friend when you want help with your phone. There is so much bad information that is easily found when using Google (same with YouTube). If you are not sure what you're doing, how can you verify a random article/video is giving good information.
Better to stick with XDA where many members can verify info and advice. XDA search is your friend.

You need to format data whenever you flash over MIUI (or MIUI derived custom ROM).
Flashing over another AOSP ROM you won't need to format data. However it is strongly advised to remove lockscreen security before updating a custom ROM or flashing a new custom ROM.
