WiFi Does Not Work Since CM Nightly Update - Nexus 6P Q&A, Help & Troubleshooting

I updated a to a more recent CM13 Nightly which fixes an issue with Bluetooth stuttering. The downside is that it broke WiFi for me. From what I can tell, it means I need to update my Vendor Image, which I found here.
A couple of questions.
1) If I flash this, will it wipe me fully? Just want to know if this means a full restore of photos, apps, etc.
1a) If no, do I just download, flash, clear cache, good to go?
1b) If yes, do I flash the vendor image, then the ROM?
2) Which one of those do I use?
Thanks in advance for any help provided.

1) No, flashing the vendor doesn't wipe anything.
1a) Just download and flash, no need to wipe cache. Just note that you need to use the "install images" feature in the TWRP install menu, or just flash it with fastboot.
1b) See above.
2) My guess is that the ROM has been updated to the latest, so use the latest vendor image available for this device.

[Q] Need few info regarding AOSP ROM flash

Hi all,
This thread seeks to get answers to my questions as I am trying to get a particular rom on my phone.
http://forum.xda-developers.com/showthread.php?t=2544474
Many thanks in advance.
1) My phone is in stock condition. What are the requirements? Do I need rooted access?
2) Step 2 should be interpreted as wipe data and cache, correct?
3) How do I install the .zip file? Where do I put it and do I need to run some software on PC or is it done entirely on my phone?
4) Is there something I should back up? I am not talking about settings, pics etc. Rather about some stuff like original ROM or I don't know what.
Lastly, the download links seem unavaible due to high traffic lately. Could anyone, in case he or she has the file, upload it somewhere else?
Thank you ver much!
I hope I can help you a lttle bit
1) You need a custom Recovery (e.g ClockworkMod). Root access is not needed if you dont want do backup your apps and data. You can flash the CWM recovery via Odin from a PC.
2/3) If you have installed your Custom Recovery, download the Rom zip file and place it on your sdcard where you can find it.
Before you install it make a factory reset in the recovery. Then install the rom zip.
4) It is always a good idea to backup your original rom. You can also do that in the custom recovery.
If you have more questions you can send me a private message and I can provide you a step for step guide

Root is not required, Just flash Custom recovery with odin, make backup of origional rom and flash your custom rom which you will place on sd card or internal sotrage.
Note: Make efs backup....use efs professional for samsung devices
1: Wipe Data / Factory Reset
2: Wipe Cache Partition
3. Wipe dalvik cache
4. Flash your rom

[Q] Flashing Nightly CM11 ROMs

I am sure this is a stupid question, but I've looked and not found a definitive answer so I'll try here.
I have a LG G2 (AT&T) which I have rooted/clockwork/CM11. I did most of it when I had a failed OTA send me into a bootloop. (I had rooted the stock and removed some bloat which it didn't care for). I love CM11 however, there are some issues with the M5 build that I think are solved in the nightlies.
My questions are as follows:
(1) If I start flashing nightlies am I going to loose everything on my phone?
(1a) If so? How do people handle nightly flashes and always having a phone that needs setup?
(1b) If not, how do I flash the CM rom? I assume through recovery like I did before.
(2) Is there an easier way to backup and restore my setup to my phone?
(2a) I have titanium backup, and I have backed up all system and apps. However, I am not sure if restoring that will mess things up after flashing.
So basically, I'm looking to find out how people use the nightly builds and still have a mostly functioning phone on a day to day basis?
Thank you!
Before flashing a nightly for the first time:
You will need to wipe cache, dalvik cache, and data (user data--not internal storage).
Updating to the newest nightly:
You will only need to wipe cache and dalvik before flashing the new nightly. You will not lose your setup or apps. CM has its own OTA app that will automatically install new nightlies via your custom recovery (CWM or TWRP)

Yeah once you're on nightlies, it's not a big deal. But after your FIRST flash of the nightlie, also be sure to flash the correct GApps package, which includes apps like the Google Play Store.

Not able to boot any ROM

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.

Build no.🤒✋

As I flashed a wrong PURE NEXUS ROM... For my phone accidentally without properly noticing name now I have downloaded factory .IMG of nexus 6P so if do dirty flashing by just flashing system.IMG and boot.IMG through recovery will this change my full system configuration as I'm reverting my phone full unroot+stock android+re lock boot loader and NRT requires current system so will this flashing just system and boot give me original version of nexus or not....I will wipe system before flashing or just go in recovery and flash these 2 IMG files..
There is no such thing as a "wrong" build number with an AOSP ROM. They build from source so their build numbers may be different than the ones in the factory images but they have to use the same drivers and blobs in the factory images so that everything works. You are fine where you are.
If you still want to revert to stock, follow section 11 in Heisenberg's Unlock/Root/Flash guide in the General section (basically, wipe system, data, cache, and dalvik cache then flash the system, boot, and vendor images).

I'm just asking as I use NRT for reverting the phone to stock and it asks about android platform as it must be android 6.0.1(mhc19i) but currently it is 6.0.1(mhc19j) so there will be problem...that's the main think I want to ask

Not sure what you mean, clean install a rom, never dirty flash unless you're ok with expecting issues.
Doesn't matter which build. Choose the most up to date vendor, chose a kernel or stock with stock. Job done.
If you want to revert to stock, then as the above has said, follow the tutorial to do so. You can't miss.

Problem with LineageOS

Hi all,
I'm with problems in Lineage OS.
I'm trying install Unofficial version under Official, but when I try usying TWRP, they show me this error:
" Can't install this package on top of incompatible data. Please try another package or run a factory reset"
I delete the "assert" section but the error persist.
Can any people help with this?
Thanks in advanced!

Did you wipe cache/data/system/Dalvik prior to installation of the unofficial Lineage OS-OMS? The unofficial and official builds don't mix - if you wish to switch between the two, you must wipe your device (unless you're dualbooting). Of course, by doing this, all data and your official Lineage OS system apart from your internal storage/SD card will be erased, make backups before you proceed. Your TWRP backup will live on your internal storage btw.

I don't know of a way to modify the update script, and in any case, I still would suggest your data (this is your app data and settings, not your photos and other media stored on your internal storage) be wiped along with your system. As I mentioned above, the official and unofficial builds are quite different, and trying to flash one on top of the other without performing a wipe of your system, (app) data, Dalvik and cache (no need to wipe your internal storage for most cases) will give you problems. It's even mentioned in the instructions for installing Lineage OS OMS https://forum.xda-developers.com/moto-g4-plus/development/xt16xx-cyanogenmod-14-1-alpha-t3492274
If you don't wish to wipe your device, then staying on the official Lineage OS might be a wise option.

I recall from what Silesh has mentioned is that the commits from ElementalX are present in his kernel, thus the benefits should be seen in the unofficial stock Lineage OS kernel and so you don't necessarily need the ElementalX kernel. If you wish to use the ElementalX kernel with the latest builds of Lineage OS-OMS, and there is nothing stopping you doing so, you need to flash the sensorhub firmware, else you'll lose sensors like your fingerprint sensor (if you have a G4 Plus, that is - I don't know if other sensors are affected on non-Plus models as well if you don't flash this). The firmware can be found here https://forum.xda-developers.com/showpost.php?p=71360979&postcount=2723
To install said firmware if you need it (credit to rahulsnair for the procedure https://forum.xda-developers.com/showpost.php?p=70716729&postcount=170):
Download the zip and extract, you should get a sensorhubfw.bin file. Copy this .bin file to your adb directory.
Connect your device to your computer and check adb can detect your device using 'adb devices'
Staying in adb, execute the command 'adb push sensorhubfw.bin /etc/firmware' (without the quotation marks). This will copy the sensorhub file to the /etc/firmware directory on your phone.
Reboot and hopefully you should have sensors back.
