Camera Not Booting - Nexus 6P Q&A, Help & Troubleshooting

I just got my Nexus 6P yesterday, unlocked the bootloader, flashed TWRP, and did the systemless root, and now my camera app does not boot! Anyone else run into this? I read somewhere flashing the stock boot.img fixes it, but then i'd lose the systemless root...

You don't need to flash boot.img to go systemless root. Reflash stock boot.img then reapply SuperSU Beta and you should be good.

So I downloaded the 6.0.1 MMB29M build and will extract the boot.img, flash that, then reflash SuperSU Beta, but which version of SuperSU Beta should I use? The latest seems to be v2.66, but will this give me systemless root because I want to keep Android Pay.

That's the version I am using and it is working with Android Pay. If you still get an error in Android Pay you might have to delete
/su/xbin_bind
Since /system is read only you will need to try the following
adb shell
su
rm -f -r /su/xbin_bind
If that works without errors then you should be able to reboot and use Android Pay.

Updating firmware and root?

Hi guys,
I know how rooting and flashing works but I've been using HTC devices since the nexus one so there are some differences I just want to make sure of. I got my 6P yesterday, I unlocked the bootloader and flashed TWRP. I wanted to gain root but Im not sure about flashing the modified boot img and the vendor thing.
My build was K but I got an OTA before unlocking the bootloader which updated to L. Anyway I don't know why I just formatted every thing in TWRP instead of the factory reset and I lost the OS X_X I tried to restore my nandroid with no luck. Anyway I got the factory img (MDB08L) from google dev and flashed used 'flash-all.bat' in the bootloader, the phone is running fine right now but I would like to update to the latest firmware 6.0.1+root since im not getting any OTA.
I would like to install CleanCore(6.0.1), the guide is
-> Flash Bootloader & Radio (as needed)
-> Flash CleanCore
-> Flash Modified Boot (named angler-xxxxxx-boot.zip)
-> Flash SuperSU or SuperSU Beta
-> Flash latest vendor.img (ROM & Vendor builds need to match!)
1. Should I use MMB29M factory img and flash 'flash-all.bat' like I did with the L build for the first step? then I flash new recovery?
-Flashing the rom through the recovery
2. so after I flash the rom I boot into the bootloader and flash the modified boot img with fastboot flash boot boot.img right?
3. then I go back to recovery and flash SU which I should download before.
4. vendor img is flashed in recovery too or fastboot?
Sorry for the hassle I just want to make sure.
One more thing, in this guide http://forum.xda-developers.com/nexus-6p/general/guides-how-to-guides-beginners-t3206928 at step 9, OP flashes the factroy img files separately (bootloader,radio,etc), is there a problem with using flashall.bat?
Thanks in advance and sorry for my noobish questions.
If you want to keep your data while doing this process, then yes, using the flash-all.bat is a problem. However, if you are fine with reverting back to stock(where you have to activate Android and reinstall all of your apps) then the flash-all.bat file is just fine.
That guide in the thread you linked walks you through how to update without losing data. After doing all of that, you'll just need to install TWRP and SuperSU again(do the latest systemless supersu though)

I have rooted my stock rom and gained root. I also installed exposed so i'll be fine without a custom rom for some time. There has been a report that some cameras aren't working on 6.0.1 with root so I'll wait for a while.
Thanks again

I'm pretty sure those reports are because they used the SuperSU root method that didn't auto patch the boot image(which is the version(or two versions) behind the current version of SuperSU). This is happening because people are updating to 6.0.1, but the patched SuperSU boot image is for 6.0 and the 6.0 boot image conflicts with 6.0.1
As long as you use the latest version of SuperSU then you won't have any trouble with the camera

I have tried some twrp recovery. It can enter the recovery successfully but it cannot boot normally. It stuck at samsung logo.

I've tried to dig more in it, and what I get is
1. The only way I succeed is by using KingRoot, and the method it's using is by exploiting and keeping a daemon background and the su file for calling the daemon. So that means after reboot, root is lost.
3. Replacing KingRoot with SuperSU's su file will lead to a bootloop, same as goes to installing zip by twrp.
4. In the bootloop, logcat shows that it is repeating a particular normal boot process
5. In the bootloop, using adb shell and typing "su" will not get into root, despite su is located in xbin.
6. Busybox functions normally.
Any ideas?

Hi, I'm very interesting to this discussion, because yesterday my a700yd update to lollipop, then I root it with king root, but many app eg. leandroind not function with kingroot, so I use kingroot remove script but i'm occurred in bootloop, so I reflash original kitkat firmware but the phone does'nt work correctly, so I reflash lollipop firmware and all work perfectly. Now I would ask you if there is a functionally root method for a700yd?
Ps:when I do a wipe data in recovery mode, I have an error: E:can't mount /preload.

From my current experience, no. The sad thing is I'm not skilled enough to do it myself, and seemly there is no reason that skilled devs are willing to have a head in to this not-quite-popular device.
Btw, you need to format /system partition before you flash the kitkat(well, maybe it works maybe it don't, it's just my experience.)

Nope, it will only do that if you attempt to replace Kingroot with supersu.
If you apply supersu to a clean stock boot and system partition it shouldn't boot loop.

If you have twrp installed I will upload a modified version of SuperSU which will allow systemless root on 5.0.2.
This will patch the boot image and should prevent a bootloop.

Weird, I did format my /system, /data and /cache before pushing in stock rom and supersu...
Isn't it sufficient to remove KingRoot?

If you flashed the stock rom that should remove the Kingroot and Super su binaries.
Are you using a stock kernel?
Usually only 5.1.1 and 6.0> need a patched boot.img as Samsung don't use root protection on 5.0.2 firmware.
However never say never and Samsung may may now be using root prevention in the later 5.0.2 kernels.
This means that a patched boot image is required to circumvent Samsung's root prevention.
If you have the boot.img I can patch it manually.

Hi everyone!
I found this two files, they are recovery.img and supersu 2.46. I still haven't tested them, because recovery is in img format and it has only the Chinese language. If anyone can help me translate the recovery and convert it in tar.md5 format. I found this 2 files on a700yd chinese forum. Thanks!
Same device platform. So should be compatible.

TWRP installed only with stock ROM
What causes bootloop
installing SuperSU just after TWRP install (via zip or sideload)
Other problems
installing SuperSU from TWRP built-in will cause a recovery loop(unable to get past recovery screen)

Root XT1644 on Nougat?

So I just updated to the latest xt1644 Nougat JP25.93.14-4 and am having an issue installing TWRP and getting it to stick. I installed it and even did a backup, but once I boot to System and then back to bootloader, and finally to recovery, it goes back to stock recovery. Also I am unsure of how to root this device now with Nougat. I've seen on a few sites differing methods. One site had a download for what they called a root package and it was a SuperSU 2.76 version. Another site said to use Phh SU and just install TWRP and then flash Phh. I don't want to mess anything up, can someone point me in the right direction since it seems everything in this forum is for a device other than the XT1644. Lastly, is it possible to revert back to Marshmellow using fastboot, or is that now not possible? I have unlocked my bootloader, obviously. Thanks.
After flashing TWRP you have to manually boot to TWRP without booting to system first. For rooting you have to flash ElementalX or Vegito Kernel and then flash SuperSU v2.79 SR3 or Magisk v12

I did manually boot it. I went back to bootloader, then choose recovery again and it goes back to TWRP. After I boot to system is when the issue occurs. If I go back to bootloader after booting to system, that is when I have the problem. Once I try to go into recovery again it goes to stack recovery. I am trying to install TWRP 3.0.2.0 Athene.

try latest twrp 3.1.0
I got it working. I had originally set it to read only and I think that was the issue. Reinstalled it and mounted system and then choose to allow modifications. It then worked. Now onto root, we will see how that goes.

When rooting do you still do the little systemless trick or is that already accounted for. Does the elemental X kernel play well and is it nice and stable? Thanks for the info.

If you're using SuperSU v2.79 SR3 beta ( https://forum.xda-developers.com/apps/supersu/2014-09-02-supersu-v2-05-t2868133), this already is configured for systemless, and if you're going for SuperSU, that's the version I recommend. Any versions below 2.79 SR3 appear to have created boot issues on Nougat (or required the echo systemless command to work).
ElementalX (1.0.4 stock is what you want) is stable and is essential for rooting. Don't try to root your device without flashing a custom kernel like ElementalX or vegito, else if you try to root the stock Nougat kernel, you'll likely trip anti-root kit/anti-rooting security (dm-verity, I recall?) and will prevent your device from booting. By flashing ElementalX or vegito, you'll bypass that security.
A useful checklist to follow is in this guide here: https://forum.xda-developers.com/mo...de-root-moto-g4-plus-supersu-android-t3587918 Having a newer version of TWRP shouldn't matter (and in fact may present less issues). With step 6, you may choose to flash either magisk or SuperSU as mentioned by tywinlannister7 (I've not had experience with phh superuser, so cannot comment). If, at some point in the future, you wish to swap rooting methods, I'd suggest following the recommended unrooting procedure for your existing root manager (e.g. unrooting from the SuperSU app settings, or flashing the magisk uninstaller, check their respective pages on XDA) before changing root managers. I've used the aforementioned checklist to root a XT1642 on Nougat without issue.
As for downgrading your system to Marshmallow if you so choose, that is possible. Verify the MM firmware you need (a selection for XT1644, retus channel devices, is here https://mirrors.lolinet.com/firmware/moto/athene/official/RETUS/) and use that firmware with a guide like this: https://forum.xda-developers.com/moto-g4-plus/how-to/guide-downgrade-to-marshmallow-nougat-t3515961 If you're using fastboot rather than mfastboot, replace mfastboot in the provided script with fastboot.

NO! NO! NO! Do not use the systemless root method. That is for Marshmallow ONLY!. You will not be able to boot into the system after trying that and you may have to go all of the way back to flashing stock from fastboot to fix it.
ElementX-G4 kernel plays well with Nougat stock. I ran it with stock Nougat for a couple of weeks on my XT1625 without any major issues. So flash it from TWRP. Be sure you have the correct version. Then boot to system to check it out. Next reboot to TWRP and flash SuperSU 2.79. Boot back to the system. It will probably boot a couple of times before the system comes up. Don't panic. You should be good to go.

Generally you'd have to revert back to a clean stock ROM, no TWRP, no ElementalX, no magisk. The stock ROM also needs to be in a read only state (no modifications allowed in TWRP) and cannot be debloated (OEM partition needs to be untouched).
You could revert back to a TWRP backup made before you flashed ElementalX, provided you did not let TWRP make modifications. You'd also have to find a stock recovery (if you flashed TWRP), and restore a stock logo.bin as well if you flashed a custom logo.bin to hide the bootloader warning. Then, you should be able to apply OTA/security updates. Attempts to apply OTA updates with TWRP on your device will likely fail and leave you in a soft bootloop unless you boot via the bootloader. You could try this to break the bootloop: https://forum.xda-developers.com/moto-g4/help/troubleshooting-twrp-boot-loop-ota-t3714325
The easiest and safest method I've found is to re-flash the stock ROM you have. Ensure this is the same firmware as you currently have and the latest firmware that you've flashed onto your device (don't downgrade your firmware if possible). You can re-flash without erasing your data by omitting the fastboot erase userdata command. However, I would recommend you back up your device anyway (e.g. in TWRP) and any important files, as although this procedure should not affect your data with that command omitted, any firmware flash has the possibility of affecting your device stability. That may require a factory reset/device wipe to fix. Backing up your data should be standard policy when it comes to flashing anything affecting your device's system/underlying firmware.
After re-flashing the stock ROM, you should be able to apply the OTA update.
Thanks a lot for the detailed answer. I really appreciate people like you. [emoji3]

magisk works without problems
Instead of flashing TWRP as the permanent recovery, just boot to it by putting your phone into Bootloader mode and use the command Fastboot boot twrp.img (replace twrp.img with the filename of your twrp). Then you can install either SuperSU or Magisk as you desire. If using SuperSU, I would recommend using the SuperSUConfig to ensure that it is installed in Systemless > SBIN so that you can then install SUHide in order that you can get the likes of Snapchat working. Magisk of course has this all ready built in so you don't have to mess about flashing extras.
All being well, your device *should* then be able to accept any further OTA's, although I wouldn't hold my breath for any further ones being released.
You might also want to look at Flashfire by the same chap who gave us SuperSU.

Thanks a lot! The only problem was that suhide doesn't seem to want to flash. However my root works and so does my snapchat
Edit: Logging out of snapchat wont let me log back in? So is there any way to hide the root?
Edit 2: Nvm. You have to flash SuperSu-SR4 instead of the normal 2.82 one. I was now able to flash suhide and get everything working

[Q] Successful rooted, but /system is read only?

Hi guys, I have successfully rooted using temporary TWRP + modded magisk method, but now I gain root and checked via Root checker. But the problem is most of the root functions don't work as /system is read-only. Any idea?
Ya i have an idea.. Happened to me as well. I tried almoat everything but system won't be accessible anywhere.. I followed the same tutorial and installed magisk 13.4.
The only solution i could find was flash the latest factory image, and root again using supersu. I used the AIO tool by ghpranav and have got my phone rooted with xposed working without any issues.

I also fixed the issue. I flash the modified boot image and I am now gaining proper root access + Xposed. Get it working using Super SU, idk why Magisk keep failing thou. Was wanted to give Magisk a try, but it doesn't work properly on our device.
Cool:good:
Xposed isn't working with magisk? I was planning to install it

Only with SuperSU as I know.

Guys, this is Magisk from Pixel. You can't expect that it is working. I wrote to MagiskDevs already, they are working on a own Version for Mi A1. Use for that time normal SuperSU (Xposed works normally )
how to??

You need flash back stock boot image first, due to some limitations you can't have TWRP and SuperSU root at the same time. If you don't have the stock boot image. I suggest download the ROM from MIUI and then flash it. You can choose "flash_all_except_storage" option, this will keep your data.
http://en.miui.com/download-333.html
After flashing. Reboot back to fastboot and then:
Code:
fastboot oem unlock
After that just run root.bat from the cf-auto root folder you downloaded and wait for it to automatically reboot your phone. You should have root now, if you wish you can download SuperSU from the store.

Ok, thanks. It's not possible to do that via TWRP? I don't have PC. Currently my bootloader is unlocked, I have TWRP and I'm unrooted.

I actually tried before, and I tell you the results:
Option 1 TWRP installed + Rooted with Magisk
= Pretty much useless as /system is read-only. Every root app doesn't function, unless it is system-less. But system-less modules nearly all doesn't work as the Magisk version too old. And this method won't trip safetynet
Option 2 no TWRP + Rooted with SuperSU (cf-root method) -- Currently using this state
= Got proper root access, Xposed works but will trip safetynet
Option 3 TWRP installed + Rooted with SuperSU (cf-root method)
= Don't try this, will cause your phone stuck in boot loop

The best bet and possible trouble free is to first download the stock ROM from MIUI, reflash it and then root.

It's possible to root without CF-Auto-Root? Why can't flash SuperSu directly with TWRP?

No, it will cause your phone stuck it boot loop if you try to flash the SuperSU zip directly from the official ChainFire site. I think probably is the AB partitioning problem or some sort (unsure). As I said you need to run CF-Auto root to get proper root access, otherwise flashing Magisk through TWRP will makes most of the root apps does not work properly unless it also uses system-less root function.

No if you want proper root with CF-auto root you must not have TWRP installed. You either choose TWRP + Magisk (non-working root) or no TWRP but with SuperSU (working root, Xposed works too).
