Trying to Manually Downgrade from Android N Beta 3 to Marshmallow - Nexus 6P Q&A, Help & Troubleshooting

I have been trying to go back to Marshmallow from the N beta 3 preview for a few days now, but it doesn't seem to be working any way I try. I originally tried to use the OTA method by unenrolling my device because that is the way I got the preview to begin with. Every time I tried that, though, it would end in an error after trying to install the update. So i tried flashing the Marshmallow images manually using fastboot. I flashed everything, including the bootloader, radio, recovery, boot, system, vendor, cache, and userdata, but when I tried rebooting, it would be stuck on the Google logo. Can someone please tell me if I am doing something wrong or can maybe help somehow? Thanks in advanced!

Not trying to say you're lying but are you sure you flashed everything? Are you using the flash all script or are you doing each image manually?
Mainly you need to flash boot, system, vendor, and userdata. Userdata just wipes that partition.
The N bootloader and radio should be compatible with the latest marshmallow release.
My best guess is if you used the flash all it didn't work, because it never works.
If not that then maybe you got a corrupted file? Try redownloading it and try again.

Nah I don't use the flash all script. I flashed everything manually and I didn't forget anything. I actually tried this twice and used a new file the second time so it's really weird. I have no idea what's wrong

I am having the SAME EXACT issue. Found this on a search. Any solutions?

Try this command first: "fastboot format userdata" - then flash all images, exept "userdata.img".

ADB Sidleoading this file worked for me https://android.googleapis.com/pack.../53bd5f816ce0706903d1a69d50bca6cd4f52b800.zip

I'm.at work or else I would try that method can anyone try it and see what happens . I'm trying to go back to mm also

So you wiped everything and used that ? Can we just flash that or does it have to be side loaded I'm.on N it works but I don't wanna go back to MM cuz it's causing issues to others from what I heard I can keep the bootloader and radio but everything else you gotta flash would you lose root or have to re unlock the bootloader?

Okay so I'm not the only one who's having this problem. Did the sideloading method format the sd card?

Download the file and rename it whatever you want. I changed it to update.zip.
Go to stock recovery and then select update from adb.
Then type ---> adb sideload "name of zip".
You will then be downgraded to stock MM with everything working.
Well at least that's what worked for me. Because I was on Android N Preview 3. It was too buggy so I tried to manually flash 6.0.1. but kept getting stuck on the white Google logo. The above method worked for me.

Are you rooted still? Someone told me if I'm going to pure rom all I need to do is wipe like normal like when you u flash a ROM and with gaps and I'll be fine with the vender image . Or do I have to do it your way . Did you go back to stock mm or a rom ?

This didn't work for me either. I tried sideloading and it was sending the file, but it stopped at .02% and it gave me an error 7 and the download failed...This is really starting to annoy me because so many apps are really buggy for me on N

Yeah Snapchat is super buggy and my phone stays crashing when it warms up lol . But I'm rooted unlocked bootloader Android N I'm trying to stay rooted unlocked bootloader and go back to MM how can I do that ?!?!?! ?? Like I'm legit frustrated lol

Nexus 4 stuck @ X/Apps Starting - Please Help!

Hello everyone. I recently rooted,unlocked bootloader and installed a ROM on my N4. Everything was fine until I decided I wanted the stock image back on my phone. Then someone weird started happening after I flashed the Google 4.3 Stock ROM, my phone would get stuck on the x logo, forever.
I tried sideloading different roms & kernels but it would keep getting stuck forever on the ROM boot animation logo. I tried googling the issue and looking all around to no avail. I have tho,discovered. That if I wipe my Dalvik cache right after an install it would boot but would yet again get stuck on the "Android is Upgrading" starts apps... message.
If anyone has any idea or solution for my problem I would be incredibly grateful. Thank you very much in advance everyone. :fingers-crossed:

Try flashing them manually again. Use this guide and make sure you follow each step carefully.
Well, I did everything the thread said. I'm still stuck at the X logo. ( Yes, I have wiped my cache and done a factory reset via recovery ) Do you maybe have any other suggestions? Thanks.

Weird, unfortunately I'm pretty much out of ideas. Maybe its worth a try to flash the stock images of a different android version. (ie: if you flashed the 4.3 stock images, try flashing the 4.2 stock images)
EDIT: It worked, thank you so much man. Saved me from replacing it! One last question tho, I seem to have no Wifi? It can't turn wifi on.

[Q] Help! Phone bricked itself trying to update. Factory Reset isn't helping!

Last night my phone wanted to update to 4.4.4 because it's been wanting to for a while, but I know it wouldn't work because my phone is rooted. It had tried this at least 3 times before and everything was fine; download update, tries to install, fails, boots right back up. I wanted to get rid of the Update notification in the top bar, so I just ran it again thinking it'd be okay. Well, this time it bricked my phone, leaving me at a neverending loop at the boot animation. I first tried to wipe the cache and dalvik cache, which did nothing. Then I tried a factory restore, which also did nothing. Then I reinstalled the stock 4.4.3 rom I had been using, which did nothing. Then I wiped the SD card completely and reinstalled a stock 4.4.4 rom through sideload, which has done nothing. My phone just sits at the boot animation and taunts me. Worse yet, I have a 16-hour drive tomorrow and my phone was going to be the majority of my sanity during that time.
What should I do?? Is there anything I can do? Normally I would just contact Google to get a replacement (I've done this before when the 4.2 update was causing a lot of bricks,I think it was 4.2 anyway, I forgot) but I'd like to have a working phone for my 16 hour trip..... if possible. Any help would be greatly appreciated! Thank you.
Well, I never had heard of any devices that still stuck in the bootanimation after flashing the factory image. There is something really wrong.
Did you already tried flashing a custom rom? Can you boot into recovery?

I had a Vanir 4.4.3 rom on my phone that I tried to flash as well, but for some reason it went right into "Optimizing Apps" after the first boot, something I hadn't seen before. Then it got stuck at "Starting Apps...", then after a restart, it too was stuck at the boot animation.
I can boot into recovery luckily, but that's all I can do. I have CWMR v6.0.3.5. I've tried just about everything I can think of. [edit] I was able to contact Google for some live chat support and am now #2 in the queue. Hopefully they can either help me or get a replacement going. Either way, I'd still love any help you guys can give me, I'd really like to get it fixed rather than waiting for a replacement.
Okay, try this: Wipe everything via recovery and with everything i mean really everything! Cache, dalvik, storage, your whole system. There must be nothing left on your phone. Then flash a rom of your choice. Wipe cache and dalvik afterwards and see if it works

I've done that already, Factory Reset + wipe cache + wipe dalvik cache + format system/data/cache/sdcard/data/media. The phone was completely bare and that's when I sideloaded the stock 4.4.4 rom (otherwise it's stuck at the Google boot screen). I'll try it again, though.
Okay right now I'm using the Nexus Toolkit to flash the stock 4.4.4 .tgz image directly from google and unroot my phone (checking the option that the phone is Soft-bricked/Bootloop.
....Okay that finished and I'm still stuck at the boot animation and now I don't have CWMR. ****. [EDIT] But I can still boot into a custom recovery through the toolkit, which is good.

Damn, I really am stumped right now. That's really strange. Normally everything should be fine after a factory reset...
I've search several threads with bootloop problems, but none of them have this persistent bootloop. I believe you have damage your storage somehow, so that the system can't read the files and boot up properly. Maybe because of this 4.4.4 OTA update. Man, that's kinda sucks right now...

I forgot something! Did you also flashed the 4.4.4 binaries?

I also read somewhere, that the LG Fashtool may help.
Try this out!

Hm, I didn't think I'd need to with the factory image, but I'll try that. I tried the 4.4.3 factory image as well but that didn't work either. I also can't find anything about the LG Flashtool that's Nexus 4 specific, but I'll try to look more into it.
Wait, how do I flash the binaries since they're .tgz files?

This is really strange man. Flashing stock ROM is the last resort but even that seems to be failing for you.
Have you tried downloading the stockRom again (just to make sure it isn't corrupted). Also, maybe you can try using TWRP instead of CWM this time.
Good luck.

No need to flash them, since you are on a factory image, sry.
Woah now, I've made progress! Maybe.... Anyway, in TWRP, I "fixed permissions" and mounted "system" but now I'm at the "Android is Upgrading, Optimizing Apps - Starting Apps" screen again (it only had to optimize 23 apps?). I was at this issue before when I was flashing roms last night trying to fix it, but going back to here is better than not getting it to boot at all. What else should I try next?
Note: I'm on the 4.4.4 factory image now and TWRP is just temporary through the Nexus Root Toolkit.

And? Did it boot up or just stuck in 'optimizing apps'? I would suggest to try another android version, like 4.3 or 4.4.2 at least.

What about custom ROM? Cyanogenmod maybe? Make sure to downlaod the M7-Release.
Hm, alright, I'll give that a shot.
On a side note, is there a way to lock the bootloader again while in either recovery or bootloader? I fear that if it's unlocked, I won't get the $250 refund for the replacement.

PLZ HELP!! Nexus 6p keeps booting into TWRP menu

Today and after deciding to simply restart my Nexus 6P, it booted into TWRP menu, I tried to reboot again, but no luck. can someone please help?
is there a way to get off the TWRP menu and boot my phone normally?
Note: The root used to simply work fine for about a month now.
Did you take an update? Rom details? You basically said you stuck a fork in a microwave and it sparked.

I will have to call you out here buddy. If you have indeed tried to flash all factory images, you won't even have TWRP in the first place.
Go to this wonderful guide by the wonderful @Heisenberg, and scroll down to "10. How To Flash The Factory Images (And Return To Stock)". You will find very clear instruction on how to return your phone to its factory stock state. This will most likely get rid of the problems you're facing.

Plex VR and Lineage

Anyone having this working? It appears something doesn't work right as the screen is a big single screen (not the dual lens type thing of VR apps.) Some have suggested build.prop changes but they were met with mixed success it seems.
Anyone got this going and what did you do?

I got this and decided to go back to stock because I been eagerly waiting for Plex VR. Going back to stock was a very long 2 day process I never want to go through again but was well worth it. Plus stock isn't really all that bad.
Well, there is no way I'll go back to stock. Not only an arduous project going back but I do enjoy LOS far, far more than stock.
Thanks mate

I used the Axon 7 toolkit and couldn't get back to stock because XiaoMiFlash kept giving an error. Had to use MiPhone instead and then was able to flash stock files.

MiFlash (and therefore axon7toolkit) is the last place you should go to. Imagine that the connection breaks somehow. Power surge, the USB cable getting disconnected, anything...
Going back to stock is as easy as flashing it via TWRP or flashing the stock recovery img and installing an official zip.
