Cannot boot any ROM - Nexus 6P Q&A, Help & Troubleshooting

Ok, I think I'm in a deeper trouble than usual.
I've made a nandroid backup like usual and flashed the latest Dirty Unicorns ROM (http://forum.xda-developers.com/nex...-dirty-unicorns-v10-0-official-6-0-1-t3326798). It didn't work as well as I had hoped - was getting force-closes on practically everything. So I wanted to restore the backup. It restored, but didn't load. Odd, so I thought let's restart the phone. So I did, but the phone just kept sitting on the DU logo and not load at all. Ok, so let's clear both Dalvik and Cache. Still doesn't boot, just sits on the logo. Ok, let's factory-reset the phone, re-download, re-install the ROM, clear everything and try again - still the same, never boots. Ok, super weird by now, never happened to me before. Already took out the trusty old Nexus 5 as the backup, as things are getting more complicated.
So I tried flashing two other ROMs (CM13 and Exodus), but the same thing happens - it just sits on the respective ROM's logo. Can anyone tell me what's happening? I'm including a pic of my bootloader. Looking at the BL and Baseband values, they looks different - are they supposed to be the same?

Might be worth going back to the latest stock build to get all your firmware in order then flash a different rom afterwards.

Ok, don't know why or how it happened, but my TWRP version was still on 2.8.x.x, even though I'm sure I flashed the newest one. I flashed the 3.0.2.0 again, but the situation is still the same.

http://forum.xda-developers.com/nexus-6p/general/guides-how-to-guides-beginners-t3206928

Yep, all good now. Followed all the steps, loaded stock images, flashed custom recovery, followed by the ROM, all good now. Thanks a bunch!

Was too quick to report success - now my SIM doesn't work. It populates the APNs, says LTE from the quick slide menu, but stays on no signal in the status bar, plus errors out when refreshing web pages, etc.
I've tried flashing different (including the latest) vendor images as well as different radios.
EDIT: never mind; the freaking Mobile Data was turned off (why the **** does it happen?). Turned it back on; all good now.

Slimbean 4.2.2 Build - media issues

Hi all,
I recently installed the newest build of Slimbean. I am having a few issues: I am unable to play any media... Music, videos (youtube). My phone app does not work. I cannot receive nor send any calls. And my phone produces no sounds at all.
I tried installing build 7 to see if it was an issue with the build I was using... didn't help.
Internet and wifi work without any problems.
Galaxy S4 i337m
Baseband: I337MUMUAMDL
Version: Slim-4.2.2.build.7-OFFICIAL
Build #: slim_jfltecan-userdebug 4.2.2 JDQ39E eng.blk_jack.20130706.15730 test-keys
Any ideas?
Thanks in advance
Update: Any ROM I install... Phone and sounds do not work.

I'd Odin back to stock and see if you still have the issue. If you do it's a hardware issue.

I did just that... But it's a bit of a story.
I had just fixed another problem I was having yesterday. Was getting stuck at the S4 splash screen right after powering on the phone. The problem was caused by TWRP 2.6 and formatting /data partition. Long story short, I installed CWM and used it to do a full wipe/format of partitions and then was able to install ROMs, restore backups without issue.
So today, since everything was working, I decided to flash a new custom ROM (which I installed) and the MG1 radio. Wasn't having any luck with the radio. Finally, I was able to flash a radio via mobile odin, but then I soft bricked my phone. Got stuck at the S4 splash screen (same issue I had yesterday, but this time, a different cause). So was troubleshooting it all day. Tried to go back to stock, no luck. Tried to restore the stock backup I had, no luck. Only thing I could do was install custom ROMs at this point to get into my phone (i.e. Slimbean, FoxHound, etc...). But, at this point, although I could boot into Android, I had no sound at all and couldn't play video. So after hours of trial and error, I installed CWM again (replacing TWRP 2.5.0.2), did a full wipe/format and tried to install a stock ROM. No luck. Still was hanging at the S4 splash screen. Then I tried to install this ROM again which I had luck with in the past; |ROM| |★VLUAMG1★| |CANADIAN||i337M||STOCK||ROOTED||July.26.13|. But his instructions said to install a wifi fix or fear soft bricking my phone. So I installed the wifi fix, but selected the wrong file (I know, stupid. Done a lot of stupid **** in the past couple days with this phone). Now, after the phone rebooted, I would see the S4 splash screen for a split second, and it would auto load into download (odin) mode. Couldn't get into recovery at all. So then I decided to flash one of the stock ROMs I tried earlier that didn't work, but this time, SUCCESS!!!!! Phone was booting and all sounds worked. I could make/receive phone calls as well... Everything seems to be working fine now. I find it funny that flashing a wifi fix that I shouldn't have seems to have fixed my issue in a sense. Since it allowed me to successfully flash a stock ROM. So I am making a backup of the stock ROM and will decide what I'm going to do from here.
Holy goalie!!! It's been a very vexing couple of days.
Nice that you got it all worked out, I've found out that if your "status" is custom, it will sometimes give you problems when flashing a "stock" rom via odin.
So what I always do when reverting back to the stock rom, I use triangle away to clear the flash count and make my phone back to "Official". If you want the steps to do this, let me know, it's not hard, but there are crucial steps to get this right!

[Q] Can't wipe or factory reset encrypted phone

I made the mistake of encrypting my phone and am now paying the price. It is rooted and I had installed the Google Edition 4.4.2 ROM by Danvdh, Kryten2k35 & Ktoonsez. I'm using TWRP 2.7.0.1.
I first tried going into recovery and doing a factory reset and got the an "Unable to mount '/data'" error, followed by a big red FAIL. So I rebooted into the system and tried to do a factory reset from there. Went through all the steps, phone rebooted into recovery and I got the same error - unable to mount.
So I did a bit of searching on the forums here and someone had suggested using the format option in TWRP. So I did that and it seemed to work - did not get the dreaded unable to mount error. So I tried flashing the new rom (the updated version from a couple of weeks ago). Got a message indicating it was successful. Rebooted, and to my dismay, got the prompt for the encryption password. Saw the little line drawing Android, then... nothing - I found myself in brick land.
Managed to get back into TWRP and, based on another post I found, tried Advanced Wipe, selecting everything except Micro SDcard and USB-OTG. Tried installing the new ROM again, says successful, but nothing has changed - I still boot into blackness after inputting my encryption password.
Not sure what else to try. Any suggestions would be most appreciated.

Can you go into download mode, revert back to a stock rom (or flash a stock one or something) and turn encryption off? edit: on further research it looks like the only way to completely unencrypt is to reset your device. dunno if that's something you'd want to try, but considering you already wiped multiple times.. i'd say try it?
Also what carrier do you have? That's pretty important. AT&Ts i337 and Verizon's variant cannot flash AOSP roms (more specifically, kernels) due to the bootloader being locked. That might be the issue you're experiencing? I looked up the ROM and it's using ktoonsez kernel, so I imagine that'd be why. Someone just made a version that does not include the kernel and has multiple issues the ROM you're trying to use fixed here.

Thanks - that's exactly what I've been trying to do. I haven't tried reflashing back to stock with Odin though. Hmmm...

Bell, up here in the Great White North. I don't think locked bootloader is an issue - I was on the previous version of Danvdh's ROM, and everything was hunkydory. I just made the unfortunate decision to encrypt. Big mistake.
May try flashing back to stock. Nothing to lose, at this stage...
Thanks!
Hey just wanted to mention for the benefit of anyone else who got into this bind, flashing back to stock using Odin did the trick. Still wouldn't boot, but then I rebooted into stock recovery and did a factory reset, and finally was able to reboot back into stock. What a nightmare. Ugh. Thanks for the tip though - never occurred to me to try to go back to stock. Lesson learned though - no more encryption for me!

Good to hear. Should be able to flash to the rom once again no problem now that it's unencrypted!

[solved] Phone is acting weird ... random reboots shortly after boot

Hi there,
I started this topic because I am out of options and I don't know what to do at this point.
My Phone is a XT1562 DualSim.
I recently flashed http://forum.xda-developers.com/moto-x-play/development/rom-spetrum-mm-volte-t3462690 and I also installed "MODEM" (MPD24.107-70) from page 1, but not right away.
First I wiped everything expect "internal storage". The phone booted but it restarted during boot (which might be okay) but then it rebooted again during boot. The boot process finally finished and I got to the screen "Android is starting - Optimising app x of y." The phone rebooted even during that process and that is definitely not normal I think. So after a couple of reboots android did finally optimise all apps but the phone did still reboot withing the first 30 seconds after it was booted.
From here I did a lot of testing and doing. These are my findings:
- When I set phone to flight mode / airplane mode it does NOT reboot... Hurray!
- When I flash another ROM (Official CM 13, http://forum.xda-developers.com/mot...m-cyanogenmod-13-preview-moto-x-play-t3252255) the phone runs like a charm, NO reboots whatsoever.
- - But as soon as I flash gapps and the phone is booted, I get the reboots again (usually within the first 30 seconds).
- - Again setting the phone to flight mode prevents itself from rebooting.
- - Apparently it doesn't matter what version of gapps I flash. I even tested the light version (ARM, 6.0, Pico, from http://opengapps.org/). It still reboots. I also tried gapps mini and stock.
Oh and I don't think its MODEM (mentioned above) related, because I faced these problems already before I installed / updated the MODEM. Well I thought its MODEM related, that's why I went back to MODEM stock version MPD24.107-52 but that did't help either. I should mention that I am not sure if I had MPD24.107-52 installed originally but spetrum (the rom developer) pointed me to that version: http://forum.xda-developers.com/showpost.php?p=69129552
I also restored my working TWRP backup from an android I used for month and guess what, yep, reboots
brrrrr this is frustrating
I never experienced that before and frankly I am out of ideas.
Anything is welcome and appreciated
Thank you
If nothing helps reflashing the whole firmware is always an option

Thanks I haven't done that.
To be clear, you mean firmware as in stock rom / factory image?
I always go back to flashing stock rom with rsdlite whenever things went wrong and I can't solve it by flashing small fixes.

I mean full stock firmware you flash with fastboot or RSD. Roms are usually only system + kernel, so not very helpful in your case
Guys! Good news. I did go back to stock firmware and from there to official CM13. Of course I had to root and install TWRP again but it was worth it.
I lost a few days spending my time with it but I'm glad its all good now thanks to you.

Frustrated after installing O and downgrading to N.. things aren't the same

TL;DR O was janky after dirty flash so downgraded but now N isn't right even after super wiping everything and reflashing stock N image.
Ok so I have no idea why I decided to try out O with all the dumb bugs that are being reported and the lack of a simple night light enabler but I did anyway. Phone was working great on 7.1.2, had the night light and blue pixel accents, the round icons actually just showed up for me which I like better than all the craziness of 5 different shaped icons cluttering up everything.
I dirty flashed stable O and it was janky as hell so after a few hours I decided to downgrade using my nandroid backup I just made. All seemed fine until I got in my car and noticed Bluetooth share was broken which kept causing force closes. I tried everything to fix it but nothing worked, had to end up reflashing latest N image. From that point all went downhill.
Phone will not show all the round icons anymore no matter what (play store being one that I totally despise being that huge play button, music, games, photos, movies, maps, etc but phone, messages, camera contacts and a few other are working), assistant would not enable and only screen search was there, Google drive backup isn't working either even with turning it off and on but it just says it's disabled by the administrator (??), I even went in to twrp and wiped EVERYTHING 3 times under the advanced menu and chose to repair the system and then fully ADB flashed the stock N image again.
After that, I rooted with magisk but now BusyBox won't install as systemless to the su/bin folder, I flashed both the night light only and the full pixel mod from gerard hoping it would enable the round icons on the GNL but it didn't. I tried flashfire to flash the N system again to clean that up but it just turned the phone off every attempt. I finally got it to work by reinstalling magisk but it didn't actually flash the system even though it went through the motions and said it was successful. I had to do it again for it to work but everything just seems weird now. What the F am I doing wrong? I know it's not a pixel thing for the round icons bc my wife's Moto z force just got 7.1 this weekend and the round icons showed up for her with no mods, no root, and she has GNL like me.
Help?
Try downloading a custom ROM like Nitrogen or Aquarius. Both of those have the options you want without having to flash any other mods. As for Google Assistant I've only had luck using Beans Gapps full package or open Gapps stock package. I personally prefer Beans. Do a full wipe before you flash and you should be good.
First of all, you went from N to O with a dirty Flash.... Of course there will be bugs. If you want to go back to N, Flash N image(boot, vendor, radio, system), when it boots up, go to settings and then perform a factory reset. After that, you can restore your Nandroid backup.
Thanks All,
Yes I do understand the issues with going from N to O on a dirty flash which is why it was janky and I decided to roll back. As mentioned, I used TWRP to wipe everything 3 times and then reflashed the latest stock N image. Google assistant worked after doing that and the interesting thing I found was if I disabled or deleted apps from the phone and then redownloaded or reenabled them, the round icons began showing again (i.e. google play, docs, sheets, etc) so that issue is resolved. I did not use the nandroid backup I made, I basically just started over from scratch and even though the Google Drive backup is still showing "disabled by your administrator", I see a new backup that was made this morning at 6:13am. I also installed busybox through magisk now rather than the separate app so I guess the only thing left outstanding is why the phone still says the Drive backup is disabled by an admin.
I would grab Nexus Root Toolkit, I install to C:\NRT, download the full August Nougat image, save it to C:\NRT too, then do a complete stock restore, this will wipe everything off phone.
Put you back to starting line and then race with flashing and mods.

I did use wug's toolkit to flash over ADB. I wonder if the image might have been slightly messed up even though the SHA-256 matched. I could always try to redownload the image again. I was going to wait until 8.0.1 was released to try O again but when I did have O, the backup options were stuck on "waiting for backup" (the menus are slightly different in O) and it never seemed to move forward. I researched that and I guess it's a known issue with some phones and a fix is supposed to be coming out this month but at this point, who knows.

Toolkit? FFS- fully wipe your device and install full 8.0 image. Done. That is what a full image is for --> janky.

I don't think you are fully understanding what the situation is. I have said now 2 or 3 times, I have completely wiped the phone 3 times in a row using twrps advanced settings and I flashed the latest stock N image. The only reason I used wugs toolkit was so I didn't have to ype out all the commands to flash. After the flash was done, I manually flashed twrp again and re-rooting using magisk. Anyway, things are mostly back to normal now. I will manually flash O again at a later time.

Still wrong. Nuclear flash everything even wiping the whole twrp since its a huge leap from N under the hood. Never dirty flash and of course clean flashing still won't be enough. Do a nuclear flash, wipe everything including your storage and recovery, back it up. Don't be lazy then be frustrated at a plethora of bugs if you didn't even flash properly.

To be clear, what do you mean by "nuclear flash" bc I'm pretty sure that is exactly what I did, 3 times. Wiped dalvik/art, system, data, userdata, cache from twrp. As for wiping the recovery, that gets done during the flash of the image. So I ask again, what did I miss? Also, it's been said many times that dirty flashing can cause issues, I get it. I wasn't being lazy with trying to get back to N which is the whole point of this thread.

Recovery bootloop out of the blue.

Okay, so usually I'm quite savvy when it comes to technology, but this one's stumping me.
Yesterday afternoon, I turned my phone off to go into work. It was working quite normally before then. When I get on break, however, I find that my phone won't get past the main logo. I figure that my phone needs a reflash, so today I went to reflash the xXx rom. Still no luck. I tried flashing stock OOS Beta 3, but then my phone went into a recovery bootloop. I tried flashing those two roms several times, but now my phone just stays in a recovery bootloop.
I'm pretty sure this isn't software-related, but I want to be wrong. That's why I'm posting here first, just in case it isn't.
I didn't do anything for it to go into a bootloop, I just turned it off after a normal day, and now it won't turn back on.
If you are decrypted you need to flash the no verify zip for OOS to boot up. With xXx anything from the version of Magisk used to one of the mods you chose in the aroma installer can cause problems. Your best bet is to boot into TWRP, format the data on your phone using the option in the wipe tab, connect your phone to a computer--it will be recognized like an external harddrive--copy and paste a full ROM zip for stock OOS Oreo onto your phone and then flash it with TWRP. Also make sure you are using one of the recommended versions of TWRP for OOS Oreo. The best version right now is the one from Codeworks. Good luck.
