Help me fix my bootlooping N6P - Nexus 6P Q&A, Help & Troubleshooting

While I was on vacation my N6P (Android 6.01 MTC20L) decided it was time to give me the bootloop of death - talk about timing!
I have a recent backup I made via Flashfire saved on my PC but I need to get my phone booted - at least temporarily.
As I said my phone is on 6.01, but the fix offered by @XCnathan32 (https://forum.xda-developers.com/nexus-6p/general/guide-fix-nexus-6p-bootloop-death-blod-t3640279) is for Nougat and above. So what are my options?
- Should I use fastboot to upgrade to Nougat or Oreo then apply the fix?
- How do I dirty flash N or O without losing my data?
- Any ideas on the heating notion? Some people have had their phones working using a blow/hair dryer..is it dangerous to heat the phone? Will any parts get damaged?
Any response would be useful to me, thanks!

More information would be useful to determine whether you really have BLOD or just bootlooping. What were you doing when it bootlooped? Was it just spontaneous? Are you able to access stock recovery or TWRP? Do you have a stable fastboot mode? If so, two options to try would be to use ADB to update using a newer version full OTA (eg. 7.0.0 (NRD90T)) or flash a full image (not OTA) with flash-all.bat, removing the -w (wipe) switch. Both of these methods will leave your data intact. If you don't have access to recovery mode (bootloops on selecting) or an unstable fastboot mode, then you are pretty much left with the hairdryer.

Thanks for the response.
- Phone was idle for a few moments thats when the bootlooping started.
- I was rooted (bootloader unlocked) with TWRP, I am unable to access it, takes me to the bootloop again
- What do you mean by stable fastboot. I can get to the fastboot mode by power button, volume down, remains there (if that's what you mean?)

No access to Recovery mode is one hallmark of the BLOD. Without Recovery you have no ADB, even if it was enabled previously. Stable fastboot mode means you can actually flash something successfully and it completes before bootlooping again. Many people who are unlocked can start flashing, but it won't finish -or- flashing completes successfully, but the phone never boots up. Try the following: fastboot format your system, userdata, and cache and observe for errors. Do these 3 complete successfully? Next, fastboot FLASH the latest TWRP to your recovery partition.... errors? Try fastboot BOOT the same in an effort to get a working Recovery where you have some additional tools. If these fail, you are looking at either RMA if eligible or replacing the phone.

Formatting userdata will, but you won't be saving anything if you can't access recovery. If you like, try formatting system and cache first. Look for errors. Then try fastboot flashing or fastboot booting TWRP. The action of formatting each partition will tell you if there is a problem with the internal memory, and correct it (if possible).

OK so I did fastboot format cache, finished fine (see attached)
Haven't done format system, is it safe? what will the system formatting erase?
As for TWRP do you mean fastboot flash recovery twrp.img?
EDIT: after the cache format I'm getting 1-2 red LED flashes before each bootloop, is this the battery being down? If I turn off the device, hook up the charger it shows a full battery with electricity charge sign and phone boots again to bootloop.

System is a read only partition. Formatting it will not cause any data loss of yours, but will temporarily render the phone not bootable... BUT It can easily be restored via fastboot from any factory image. You just extract and flash the system image back to the system partition. Userdata is your personal data. When you format that partition your personal data will be gone. You did mention you had a FF backup so I'm guessing that was on the backup.
Yes on flashing TWRP. If after FLASHING twrp you cannot access Recovery, then try BOOTING recovery- fastboot boot recovery twrp.img
If you get to a point where nothing is working and you decide to format system and userdata and they complete successfully, you can flash a full Google image using flash-all.bat
Not sure about the LED's but just make sure your battery is close to fully charged. You didn't ever mention an battery issue, so there shouldn't be one. If in doubt hook the charger up and let it sit before proceeding.

@v12xke
Thank you for all your help. I left the phone on charge and let it bootloop for a good period of time and went out, came back and it was booted. I disabled the big clusters as suggested by @nicotinic in ElementalX and the device appears to be working fine aside from a little lag. I can live with that
Currently doing a little ADB pull, then will clear some space for a full nandroid backup!
Thanks a bunch to you both.

Help help help with a hard bricked 6P

Hello guys,
I had my phone rooted with latest twrp. I flashed stock+ rom with Franco Kernel 25r and the A.R.I.S.E file for better sound. I've done the same set up minus the ARISE file and never had an issue.
well to my luck it kept bootlooping and I wasn't able to get back into my custom recovery. When I got home and got my hands on a pc I did a factory reset by manually flashing stock google img . I even used a couple tools since I ran out of ideas and still no luck.
I'm able to do anything through fastboot but I can't seem to get into my recovery at all.
Any ideas or tips of where I should go next?
Not a Hardbrick
As long as you can get to the bootloader mode, you haven't hard bricked your device. Hardbricking is a point where you cant boot your device and in to bootloader so there is no way to flash your device to a useable state.
Now as you can boot to the bootloader, just fastboot boot twrp.img and if you have a factory image zip, copy it in your device internal storage and flash it. Its that simple, provided you are already using an unencrypted boot.img in your current setup. Or else the next step is to flash an decrypted boot.img(you will loose all your userdata and internal storage data.). There are ways to mount the the encrypted filesystem if you are using a pin or password combo with your fingerprint. But without it its a bit more trickier so just for ease and if you dont have any inseparable data in your device now just flash a decrypted boot.img and then you can easily mount your internal storage to your pc and copy the factory image and the rest you already know..
At this point, I'd recommend a full reset.
Flash all the images in the latest Android M factory image (don't flash DP5 or similar N based ROMs): Recovery, Boot, System, Bootloader, Radio, everything.
Once you get stabilized and back into a working phone, then start rooting and messing around with kernels and what not.
To be completely honest, I've flashed nearly every ROM for the 6p, as well as my other Nexus devices, Galaxy phones, Sony phones, and no-name brands and none of those ultra modified kernels did any noticeable change. I tried the F2FS, NTFS, etc file system changes, tweaks to the governors and IO's, all of that, and found the stock kernel was the best. If a kernel with a different IO Scheduler worked even 10% better than the current implementation, and was just as stable, don't you think the Google/Android Engineers would've pushed that to live?
Currently running Pure Nexus July 23rd Update, everything stock that comes with it, Systemless Root/XPosed, and Viper4Android and have never had a performance or stability issue. I'd recommend you do the same.

First of all thank you for the response.
I've tried flashing the most current twrp and it seems to go through fine on fast boot but when I actually try to get into recovery from the device it will boot loop and just keep doing that.
How can I get into the phones storage through fastboot?
Where can I get the factory zip?
it feels as if everything seems to go good through fastboot but when I actually try to boot the phone nothing seems to work.

Thanks for the reply.
I've done the manual flashing already and flashed everything single item the most current factory image. Everything seemed to have gone through okay but when I rebooted the phone it was back to 0.
I'm actually considering getting rid of the phone now since it is my daily =/
Format each partition before flashing.
fastboot format <partition>
wait until it's done, then
fastboot flash <partition> <image>
Some partitions can't be formatted, which there are ways around, but try this first.
Just get to bootloader mode and try booting the twrp.img
fastboot boot twrp.img
From the twrp ui, go to advanced wipe and format your storage.
To mount the internal storage on your PC, enable mtp from twrp screen.
If U are using a decrypted boot.img, it will easily mount ur internal storage. Or try flashing a decrypted boot.img
fastboot flash boot boot.img
Then try the above again..

I flashed the twrp.img and it went through successfully at least on the computer it did but when the phone actually tries to get into recovery (twrp) it will start to boot loop and keep on doing that. I tried both an encrypted and decrypted boot img but it still made no difference.
I'm really going crazy over this

You need to explain more on what you actually tried here.
Just download the latest factory image and try to flash the latest bootloader using fastboot.
Then boot to the bootloader and try formating the device. Not wiping
Then you have to
fastboot boot twrp.img
I believe you have only tried wiping not formating. I faced similar issue before. But once I flashed a decrypted boot.img, it cleared the user data and then I was able to get to twrp.
Maybe your twrp img is corrupted if this didn't work.

i just flashed the latest bootloader from the most recent factory image and i did the command format user data and then tried the fastboot boot twrp and the phone will then try to get into recovery, the google logo comes up lasts a couple seconds and boot loops all over to where is says my phone cant be check for corruption
By now i should have been able to get into recovery and it wont go through

download a factory image and run the flash all file...... it should reboot your phone after 5 minutes and the issue should be resolved.. a hard brick would be a device that does nothing.... in this case i believe that you just didnt do something right.
Then download the latest factory image and extract it
fastboot flash radio.img
fastboot flash bootloader.img
& do a fastboot update the rest archive file as it is
This will flash the rom via fastboot& U don't have to rely on TWRP or CWM

I was really really hoping this would help. I erase/formated everything before flashing anything. I then ran the flash-all file and it took a couple of minutes and it said finished on the command box and my phone restarted and went into the white google logo and rebooted again with a bootloop. I waited around 15 minutes hoping it would start but it didn't.
It honestly feels as if the phone is not processing the full commands but on the pc it seems to go through successfully
is there a way to force an install of a rom and see if maybe a dirty flash over the stock one will allow it to start up?

Just unzip the factory image and there U can see the flash shell script files too. Open them in a text editor & U could see the exact command. In a factory img, they also do the same thing via script files. Flashing the radio & bootloader & updating the rest archive
so this is what I've done
I've manually flashed every file needed for the factory image from google.
I also tried wugfresh tool kit which is great but didn't help me much. I flashed stock recovery and treid to boot into to and nothing. I flashed a customer recovery and nothing.
It always does the same thing
the screen that says my phone can't be checked for corruption and then the google sign comes up stays on for a couple seconds and then it bootloops to the can't be checked for corruption.
I try to get into recovery using fastboot commands and the phone does the same exact thing.
I was even able to lock and relock the bootloader and I was able to successfully flash everything at least that is what it showed on the computer
so ive read almost every thread that had to do with bricking and I feel like an expert now but im starting to think it is done =/

Hey there. First off make sure to unlock again your bootloader. Then you may follow post # 10 of @Heisenberg 's flashing guide for our device.
First images to flash would be bootloader and radio. First flash bootloader, then make sure to issue the command adb reboot-bootloader. Then afterwards once the phone has rebooted back to bootloader, flash radio, then again do the adb reboot-bootloader again.
Once the phone is again back to bootloader flash the rest of the images except userdata. For the boot.img and recovery.img, flash the stock ones-don't use the decrypted boot.img and don't flash the twrp.img yet. Once all necessary images have been flashed issue the reboot-booloater command one more time, then on the bootloader screen choose the reboot option. Wait anywhere from 3-10 minutes for the phone to load. Let us know how it goes for you.

Hello and thank you for helping.
I tried this method a couple of minutes ago. I flashed them this same way
fastboot flash bootloader C:\angler\images\bootloader-angler-angler-xx.xx.img
fastboot reboot-bootloader
fastboot flash radio C:\angler\images\radio-angler-angler-xx.xx.img
fastboot reboot-bootloader
fastboot flash boot C:\angler\images\boot.img
fastboot erase cache
fastboot flash cache C:\angler\images\cache.img
fastboot flash recovery C:\angler\images\recovery.img
fastboot flash system C:\angler\images\system.img
fastboot flash vendor C:\angler\images\vendor.img
It does the same exact thing it will try and restart the phone, the message that says it can't be checked for corruption the google logo comes up and it repeats it self non stop.
This is what doesn't make sense to me.
This is the file that I had flashed through twrp when it was working fine

This is weird. What version of the stock factory images did you flash? I've been using leviticus 1.3 since it came out and when i was still on stock rom. I switched over to cm builds and have been flashing every nightly since the 7/24th build, and in the process repeatesly reflashing the aound mod along, and i've had zero issues with the phone booting afterwards.

Reboot loop, can't access Recovery

This is the whole situation:
I have Pure Nexus installed on my 6P, running great for months. Suddenly yesterday it rebooted while I was using it and sticking in a bootloop. "No problem", I thought, and wanted to reboot into recovery - but nope, can't access it anymore. So I tried to reflash the recovery when I got home, but I only get errorors
When using the command adb devices the line just stays blank. The same with fastboot commands, besides "Fastboot devices"
After messing around a couple hours with the drivers and so on, I managed to somehow get the fastboot command working again. But no sign for the ADB commands, probably because I didn't turn on USB-debugging.
I am now at the point, where I have reflashed Stock Android with the Nexus Root Toolkit and managed to get back into stock android recovery, but still can't get TWRP to boot. I didn't want to delete my personal data, but I saw no other way and formatted /data in stock recovery. But the problem with the bootloop is still there.
It's not the classic bootloop, it boots as far as the Google Logo, then shuts itself down and begins again. I have now reached the point where I have to say, that the hardware might be damaged too. I'd love to somehow get access to the internal storage at least, but I can't without a working ADB.
Reinstalled TWRP with every available version, none of them worked. I am able to access stock Android recovery, but adb commands aren't working from here anyway.
Is there an option to fix the recovery mode? If I could get this working, the rest would be easy for me.
Edit: The reboot looks like in this Link. Only difference is, my device doesn't even the reach the dots.

If you can get fastboot commands to work, just flash the factory image per Heisenberg's guide. Toolkits are more trouble than help. Return it to fresh stock with a full wipe and start fresh.

That vid you linked is an N5 with a stuck power button. It'll do the same thing and reboot recovery as well. It could be your issue but if it is it'll be the first stuck power button I've heard of on a 6P.
When you access fastboot does it stay on in fastboot or does it reboot from it?

You contradict yourself a bit so it is difficult to help you. You got to stock recovery but you can't boot into TWRP? If you have stock recovery, of course you can't boot into TWRP. You have wiped your data but you still want to preserve your data ... Huh?
Your phone isn't working so just nuke and pave with the command line and avoid toolkits. They are sometimes part of the problem.

Your phone isn't working so just nuke and pave with the command line and avoid toolkits. They are sometimes part of the problem.

When stock recovery is installed, I am from time to time able to access it (most of the times it just ends in a bootloop)
If I flash TWRP I can't access it, no matter how often I try
I have factory reset my phone, the stuff on the internal is still there and I want to reach this, as I have my chats, SMS, university stuff and so on backed up on the internal storage
I am trying everything - all the regular adb methods, toolkits, every driver, nothing is working
Sorry if you don't understand my situation, but I am in a pinch right now
You said you have fastboot working?
Download the factory image zip file. Extract it. Extract the zip file from inside that as well. Move the img files to your platform-tools folder.
Reboot your phone to the bootloader. Hold volume down+power from a powered off state.
Plug into PC, open command line from your platform-tools folder.
Type, fastboot devices
Does it show your serial number? If so, start flashing the following images;
Bootloader-angler-angler-xx.xx.img, radio-angler-angler-xx.xx.img, vendor.img, system.img, boot.img, recovery.img
Flash with fastboot.
Code:
fastboot flash bootloader bootloader-angler-angler-xx.xx.img
Code:
fastboot flash radio radio-angler-angler-xx.xx.img
(Substitute "xx.xx" for the version number shown in the img files you unpacked)
Reboot bootloader
Code:
fastboot flash vendor vendor.img
Code:
fastboot flash system system.img
Code:
fastboot flash boot boot.img
Code:
fastboot flash recovery recovery.img
Once you do that, boot to stock recovery and cache wipe. Reboot and you're stock. If you're still not able to boot after that post back.
Edit: You said you wanted to avoid flashing factory images to keep internal storage in tact. Do it this way and you can have your cake and eat it too.
Edit2: wrong, see my latest reply

I did this already exactly like you wrote, did it again now, and I am still stuck in the reboot loop (boots up to Google Logo, then shuts itself down; repeat)
Can't reach recovery mode either
You said you had access to stock recovery before?
You already did this?

If you flashed the factory images and still boot looping you may need to RMA.
Did you restore a TWRP backup?
Edit: Sorry, it's late and I have no sleep. I was wrong. I was thinking TWRP. Factory Reset from TWRP before my steps will keep internal storage I'm tact. Factory Reset from stock recovery will wipe internal storage. Everything. You mentioned you did that already from stock recovery before i made my reply. Your data is already gone as soon as you did that. If not, your emmc is likely corrupted and you need to RMA.
Fastboot twrp 3.0.0-0 then try to access it

Yes, I think so too. I flashed the phone with the full Stock image, the bootloop is still there.
Looks like my precious is dead
At least I have my most important data like phonenumbers, pictures and SMS saved to the cloud
Gonna RMA it tomorrow
Goodybe my precious, I hope you'll be fine :crying:
Got my device back today, the mainboard was damaged, so I had no chance to get my data from the phone

This is the whole situation:
I have Pure Nexus installed on my 6P, running great for months. Suddenly yesterday it rebooted while I was using it and sticking in a bootloop. "No problem", I thought, and wanted to reboot into recovery - but nope, can't access it anymore. So I tried to reflash the recovery when I got home, but I only get errorors
When using the command adb devices the line just stays blank. The same with fastboot commands, besides "Fastboot devices"
After messing around a couple hours with the drivers and so on, I managed to somehow get the fastboot command working again. But no sign for the ADB commands, probably because I didn't turn on USB-debugging.
I am now at the point, where I have reflashed Stock Android with the Nexus Root Toolkit and managed to get back into stock android recovery, but still can't get TWRP to boot. I didn't want to delete my personal data, but I saw no other way and formatted /data in stock recovery. But the problem with the bootloop is still there.
It's not the classic bootloop, it boots as far as the Google Logo, then shuts itself down and begins again. I have now reached the point where I have to say, that the hardware might be damaged too. I'd love to somehow get access to the internal storage at least, but I can't without a working ADB.
Reinstalled TWRP with every available version, none of them worked. I am able to access stock Android recovery, but adb commands aren't working from here anyway.
Is there an option to fix the recovery mode? If I could get this working, the rest would be easy for me.
Edit: The reboot looks like in this Link. Only difference is, my device doesn't even the reach the dots.

Try flashing TWRP 3.0.2-3 or boot into twrp through fastboot. Using
fastboot boot recovery <twrp filename>.img
I think booting to twrp using this command will work.
And here's the link to Twrp 3.0.2-3 , as its not available on Official Twrp page.
https://idlekernel.com/twrp/nexus/twrp-3.0.2-3-angler.img
I had the same problem with my 5X, nothing worked I tried every possible solution described above and more. Nothing. I figured out that there was nothing to loose and followed directions from YouTube videos (links below) and it worked. Used heat gun at max temp for about 2 mins from each side. It's been about 12 hours since then, phone works flawlessly. Here are the links:
https://www.youtube.com/watch?v=SD25mdrgAys
https://www.youtube.com/watch?v=Cqh2x-TGnCY
Be careful handling the motherboard after you heat the first side, let it cool first before you start working on the second side. The same with the second side do not pick it up until it's cool.
5X, Pure Nexus Rom 7.1.2 June 5th security update, Elemental X Kernel,
has anyone found solution to this?????

I had a same issue with this device, but I had some experiment.
If your device is unlocked, you can flash TWRP, boot to recovery, wipe, format data.
Backup your data first! It will erase all of your data (Very noob answer)
Totally careful, don't do this if you didn't want a unexpected things. Or something...
The ASUS Zenfone 3 comes shipped encrypted by default. This is required by Google's Play Services agreement for phone OEMs. You cannot remove decryption on the Zenfone 3 without using a custom ROM.

I'm having the same issue. I just got my daughter this phone (the 552KL?), downloaded the official Asus bootloader unlocker APK and ran it, then rebooted to the bootloader to flash TWRP.
TWRP installed, but wants a password to unlock it. Before the bootloader unlock, I did put her Google account on the phone, but the tool said it would completely wipe the phone. Either way, I tried her google account password, but it just says wrong password. Same thing when I tried to boot to system.
Any tips?

Format through twrp

That's what I ended up doing. I got some help on another thread. The problem I'm having now is that I can't format /cache. It's really weird. If I do a full wipe on the phone, it says it can't format it. I even tried formatting it through fastboot ("fastboot erase cache" then "fastboot format cache"), which says "OKAY finished", but doesn't fix the issue when trying to wipe cache inside of TWRP.
This phone is flat out weird compared to other phones. I don't get the bootloader unlock screen. It doesn't seem to want to boot system... it just keeps going to TWRP. On the few times I have gotten to boot into system (after flashing Carbon 6.1 unofficial), it ends up hanging on a blank screen. Windows makes a sound that a new device is connected, so I'm guessing it's connecting in EDL mode or something (no devices show with a "fastboot devices" or a "adb devices").
I really don't know where to go from here. I'm used to working with Axons, Motorolas, and OnePlus phones. They just work.
@Flapjack
The cache issue is a glitch with the build of twrp, it's not a big deal. There's a workaround posted somewhere, can't remember. Just use the file browser and delete the files on it. I think there's only one file that isn't 0 bytes.
Have you flashed magisk?
Sometimes a full wipe (system/data) and then flashing the raw firmware helps. Try magisk first.

So you're saying it doesn't need to be actually wiped, I just need to go into cache and delete all the files in there? How about getting it to boot to system? It just keeps booting to recovery. Not sure when it started that, as after the first time I flashed the ROM, I was able to get it to boot to system by pressing the power button when the "bootloader unlocked" screen came up. That isn't working now.

For my first non-stock ROM flash, I flashed the Oreo modem, Carbon 6.1 unofficial ROM, ARM64 Gapps nano, and Magisk 16.0... all at once. I tried booting and it looked like it was setting up... but as I mentioned, it just went to a blank screen. After trying a full wipe and seeing the "couldn't wipe cache" message, I figured that was why.
How will flashing Magisk help me with wiping the cache partition or getting the thing to boot right? Sorry for my ignorance.

wiping/formatting cache is the same as deleting all the files. Wiping is easier but as I said, doesn't work at the moment.

magisk won't help with cache, but it will remove the verity flag that is tripped from having twrp. From my experience, if I don't flash magisk, it'll bootloop.
Yeah.... absolutely nothing I do will get it to boot to system now. I've flashed the ROM and Magisk, but no matter what, it keeps booting to recovery.
There were two folders under /cache... "Lost&Found" and "recovery". I deleted both, but that didn't help.

So I take it I did it right? I would say it's "pretty much" the same. Formatting a partition is different than deleting files/folders in an existing partition. Still, if deleting the files/folders is good enough, then that rules out why the system wouldn't boot after the first ROM install attempt. It would also explain why "fastboot erase cache" seems to work, but TWRP still throws an error. Fastboot erase is probably working just fine.

Is there a custom version of Magisk for this phone? I'm just installing the usual magisk 16.0 zip file you can get on their site, but it doesn't seem to be helping with the phone continuously booting into recovery. Is there a way to remove that verity flag via adb?
@Flapjack
Magisk modifies one of the partitions to get around the flag (I believe), not doable through adb.
Standard magisk off their site is fine
Try this:
Format system/data
Flash custom Rom
Flash magisk
"Wipe" cache and davlik
Reboot
OR
Flash the raw firmware
Flash twrp
Flash whichever custom Rom & gapps where needed
Flash magisk
Factory reset and "Wipe" cache and dalvik
Reboot

No go. Still just boots into recovery. Here's what the boot screen looks like (then the Asus logo pops up, then recovery loads)
Code:

Your device software can't be

lock the bootloader.
Visit this link on another device:

I can press the power button to boot immediately, or wait the 10 seconds... which just boots anyway (doesn't shut down). If I press the volume buttons, I get the following options menu:
Power off
Restart

That is the correct screen for an unlocked bootloader.
Try this guide for the raw firmware instead, and verify it boots to the OS. Then flash twrp and the rom again.

Grrr... no matter what I do, it won't flash. The guide says to put it in fastboot mode, but the flash tool won't detect it (even though "fastboot devices" shows it just fine). If I boot it to recovery, it'll show up in the tool, but never actually flashes (see screenshot).

This is why I stopped using Windows. Maybe try disabling "driver signature verification"? Swap USB ports? My computer has some high power and low power USB ports, certain devices won't work properly in the low power ones. A couple of guides mentioned unplugging and re-plugging the USB.

[ZE551KL] Stuck in bootloop, need complete rebuild. Help!

OK, 3 days ago I rebooted my ZE551KL and it went into a bootloop. I was completely 100% stock. No root. Locked bootloader. Spent the better part of the weekend trying to troubleshoot it, and I have made almost zero progress.
I've tried a bunch of things, but here is my current status.
Can get into fastboot mode no problem.
POWER + DOWN VOL gets me into stock recovery, but at some point I flashed an older version. I tried flashing TWRP, but after install could never seem to get into it (is that because I'm unrooted and locked?)
Current recovery version: Android system recovery <3e> LRX22G.WW_user_1.16.40.763_20151201
I've tried flashing to a couple different firmware versions from the ASUS website both via ADB and via the SD Card.
Current firmware: UL-z00T-WW-1.17.40.1531-user.zip
Still in bootloop.
Any advice on rebuilding this thing from scratch? I dont care whether I just get stock back, or if I need to root/unlock, install TWRP and a custom ROM. Dont care, just want a functioing phone!
Thanks in advance.

I dont get it. Did you factory reset your phone? With stock rom, factory work most of the time.
You said that you tried flashing TWRP. If you see successfull message after flash, type "fastboot reboot" and hold volume down button right after hit Enter. If you did right, you can get into twrp, then choses Wipe > format, it more powerfull than factory reset.

1. Factory reset from within the phone's OS? No, I cant get that far. Just constant bootloop on ASUS logo.
2. I've used the fastboot erase command to wipe everything, and used the wipe data/factory reset option in the stock recovery. Still bootloop.
3. I've tried flashing TWRP 3.0.0.0 and the newest version of TWRP. I hold down the VOL DOWN key before hitting enter on "fastboot reboot"; it just goes into a faster bootloop, like every half-second. When I release the VOL DOWN key, it goes into the same, slower original bootloop.
ACFH said:
Ok. You can format through fastboot

fastboot format userdata

Stuck on "flying color dots"

My Nexus 6P started bootloping a couple of weeks back. It used to bootloop upto the "Google" logo, but occasionally used to go past that and start up. I followed the step-by-step guide from here:
https://forum.xda-developers.com/nexus-6p/general/guides-how-to-guides-beginners-t3206928
I did the following steps:
1. How To Unlock Your Bootloader
2. How To Install A Custom Recovery On Your Device
6. How To Root
and
8. How To Install A Custom Kernel With TWRP Recovery
This, however, didn't help me fix the bootloop issue. I read on a different thread that restoring to stock has helped some folks. So I followed:
10. How To Flash The Factory Images (Return To Stock)
Now the phone sometimes reaches up to the "flying color dots", but never goes past beyond that. Can anyone help me with this situation please?
I tried to go into the Recovery mode, but that doesn't help either. After selecting "Recovery", the phone bootloops as usual. But eventually goes to "flying dots".
Any help is greatly appreciated.
Are you flashing it with the flashall script or flashing the files manually?
I had the exact symptoms the first time I flashed 7.12 because I had erased the cache partition before I realized it was no longer included. You can try: Download the last version of 7.11, which would have been around April, and extract the cache.img. Copy it in with the other images and follow 10 (or 9) in Heisenberg's How-To again and include the two fastboot image commands. That fixed mine.

Put it in fastboot mode and format (not erase) system, userdata and cache. Note any errors? Then use flash-all.bat with the latest image to (potentially) recover. Not being able to boot into Recovery mode is not a good sign.

I erased all partitions (except radio) and then tried to format all. Some failed formatting, but that did the trick.
