You don't need to keep the heat on the phone once it boots. And you can just heat it up without opening the back cover. I used a heat gun (on low setting) but it took me only 2 min. If you use a hair dryer, you may need 5 or more minutes. Once the phone boots up, just get all the data files you need ASAP. After that, even if the phone appears to be working as before flawlessly, it will die suddenly. Mine worked for 3 days before it turned into a real brick all of a sudden. So my suggestion is trade it in ASAP to google, or just throw it away. Once it turns into a real brick, it won't respond to any key press, power charge, or anything.

Hope this helps.

How much does your repairman charge to replace SoC? If it's not too expensive and you have the shipping address, I would ship it over to him/her. I will include the fee plus return shipping.

bootlooped again

nexu 6p bootlooped again after flashing boot.img with 4cores and also tried the one with 1 core

heeeelp
[Nexus 6P General] zhangla:
Use a hair dryer or heat gun, blow to the back of the phone, the area above fingerprint sensor and below the camera. For few minutes, it should boot up. However, once the phone boot up, you need to either trade it in to Google soon, or just get all your data and throw the phone away, because it may appear to work fine but it will suddenly die completely after few days. I am speaking of my own experience, which is identical to your so far.

First start - slow

Hey guys

Just wanted to check on how long does it take to get the phone booted up completed after the flash. I did the TWRP + EX method.

I am at the animation screen for about 15 mins now... Does this seem normal or I messed up somewhere?

Thanks

Zain
[Nexus 6P General] ShadowVlican:
just when I thought i could ignore this problem, ugh, my mother's 6P is now stuck in a bootloop

the device is only 1.5 years old... i won't be buying a huawei product ever again

no success with 5 minutes of hair dryer, still boot looping... not sure i want to try more because the 4 small cores have been reported to inevitably fail anyways

i guess it's time to search for a new phone
[Nexus 6P General] danielleb21:
Does this fixing of bootloop solution erase all data?
[Nexus 6P General] ShadowVlican:
so after about 20 minutes of this:

i was finally able to get here:

then followed the instructions in OP, flashed the "Boot.img from stock 6.17, 8.0 firmware", and rebooted.... it's still loading... guess it takes a while

update: forced a reboot and was automatically brought to an erasing screen that looks like this:

after another automatic reboot, i'm finally at setup!
[Nexus 6P General] 3l1k:
Nevermind
[Nexus 6P General] locolyric:
i would like to get a nexus 6p , but so confuse about this bootloop issue. We must flash this patch img files to continue to use this device ? No 8 core patch ?

i search in google, there is only fix for bootloop. But no explain why bootloop happens.

is it a hardware defects?
[Nexus 6P General] 3l1k:
Yes, hardware issue and no 8 cores patch. I will not recommend you to buy 6p
[Nexus 6P General] locolyric:
too bad. because i compare to the same flagship of apple in 2015, and the price is way cheaper.

if there is no hardware issue, i sure will get this phone because i love the camera quality and design.
[Nexus 6P General] XCnathan32:
Your internal storage is probably encrypted, you can get around this by doing a factory reset, if you don't want to do that, you can also try sideloading the zip, might not work as well though.
[Nexus 6P General] XCnathan32:
It only works for 7.1.2 as of now, I can make one for Marshmallow if you would like.
[Nexus 6P General] outbackpaul:
I did the factory reset. Now in TWRP I can see lots of folders but after looking through several folders I don't see any files anywhere.

Maybe that's why I'm stuck and the skipping dots?
[Nexus 6P General] XCnathan32:
Make sure you were on 7.1.2 stock firmware before you flashed the boot.img. I once got that problem when I accidentally flashed the wrong boot.img version.
[Nexus 6P General] XCnathan32:
The snapdragon 615 uses a53 cores, which are the little cores on the Nexus, the a57 cores on the 6p/5x/G4/V10 always seem to be the problematic ones, so you may have another issue. However, it could be an issue with how the Big and little cpus communicate with each other.

I don't know of any other methods to disable the big CPUs, but there's most likely a way to modify the ramdisk to disable them. The Big.LITTLE configuration typically labels the little cpus first and big cpus next (ex: Cpu 0=little, Cpu 1=little, Cpu 2=little, CPU 3= little, CPU 4= Big, etc.) So putting maxCPUs=4 in the .cfg file makes it use the first 4 CPUs (0,1,2,3, so, just the little cores) You can verify that 0-3 are little cores by looking at CPU-z on another Xiaomi mi4i, and you should see that cores 0-3 run at 1 GHz, whereas cores 4-7 run at 1.7 GHz. You could also try setting boot_cpus=0-3 in the config, however, that setting didn't seem to make a difference for me.
[Nexus 6P General] XCnathan32:
Try flashing the twrp image, and then the modified EX kernel zip.
[Nexus 6P General] XCnathan32:
My log shows that CPU4 has errors with not initializing and failing to get VLL lock, but I'm not sure if when a failure occurs, the kernel doesn't attempt the load the cores after it, and that's why CPU4 (the first big core) is the one to fail. It would be very weird if Qualcomm manufactured millions of SoC's that had defects in just core 4 exactly.

Today I am going to do some testing with running the BIG cpus at really low frequencies and seeing if that works. If there would be a way to re-enable some cores, I would guess it involve modifying the ramdisk, however, I would have to look into that more.
[Nexus 6P General] XCnathan32:
I have PureNexus rom, Ex kernel OC, Disabled animations in developer options, turned on Force GPU rendering and Disable HW overlays in developer options (I have only tested for a few minutes as of now, but it already seems to be making my phone faster) and turned my screen resolution to 1080p, It runs as fast, if not faster than my Debloated Galaxy S7.
[Nexus 6P General] XCnathan32:
Make sure all your partitions are mounted in TWRP, if anything other than the data or sdcard folder is empty, that's a problem, if it's just those 2 folders, then you should be fine.
[Nexus 6P General] XCnathan32:
Damn :/, well the only advice I can give you is generic advice, such as reflash stock image and try again, although I'm sure you've already tried that, but hey it can never hurt to try again.
[Nexus 6P General] XCnathan32:
That's really weird, I don't understand why it would work the first time, but not the 2nd time, can you flash the modified TWRP?
[Nexus 6P General] XCnathan32:
The G3 does not have a big.LITTLE configuration, so I don't think this fix would work. If you can boot into TWRP recovery and adb pull console_ramoops, then I may be able to help you.
[Nexus 6P General] Bubba_:
It's alive

Did that and it worked! Thanks so much!! I'm happy to have a working phone! After this experience, I think rooting a phone isn't really that hard! I flashed my phone so many times! I plan to flash the modified Elemental X kernel V4.11.

Thanks again!!!!!!

Recording the video now.
[Nexus 6P General] kaustubhb:
Flashed boot image and ex kernel ... device booted fine noticed little lag initially but after selecting performance governor everything seems to be fine .. waiting for battery to drain ..
[Nexus 6P General] MrMarques01:
Yeah, I wasn't anticipating that it's always the same core failing for every user. However, if there was a way for the user to identify which CPU core fails exactly and then disabling this particular core only, I think this would be ideal as I think the performance hit that one disabled core causes would be minimal
[Nexus 6P General] Vermanucci:
no luck so far

I've flashed to stock 7.1.2 (N2G48B, Jul 2017), then N2G48B_4Cores.img & twrp3_1_1_4Cores.img.

:( Still boot loops and no access to recovery/twrp
[Nexus 6P General] sylforae:
Yea, everything is ok like the first time for the flash...
[Nexus 6P General] XCnathan32:
Update: OP has been updated with more performance tweaks, and a video showing the devices performance using this mod, be sure to check it out

I recorded a video here of my device performance while using 4 cores, keep in mind that recording the screen does cause some lag, and video processing/rendering may cause some more lag. (might have to pause and then play video for it to play HD)

My settings on my phone: PureNexus ROM, modified EX kernel, 1632 MHz OC, Interactive governor, 1080p resolution with 400 dpi, all animations turned off in developer options, and "Force GPU rendering" and "Disable HW overlays" turned on in developer options. Other than the little core OC, all other options were kept default in the EX kernel installer.
[Nexus 6P General] XCnathan32:
If you can flash TWRP, then try flashing the modified EX kernel in TWRP and see if that works.
[Nexus 6P General] pacoe:
Mine booted up right away. What helped me was to do the following:

1. Flash the four core fix.

2. Reboot the bootloader.

3. Flash twrp.

4. Reboot the bootloader again.

5. Reboot to twrp.

6. Wipe the dalvik and system cache.

Install element X kernel though adb sideload.

7. Reboot the phone and you should be good to go.
[Nexus 6P General] zain1291:

Decryption unseccessful

Hello forum. I ran through the procedure to install the new boot img and twrp and upon rebooting it would give me the message saying my lock screen password is correct but my data is corrupt. When rebooting into twrp it also shows my password as being invalid. I use the pattern password screen. Has anyone experienced this?

Edit- I wiped the phone through twrp fast wipe and phone booted up like factory fresh. Used ADB sideload to flash EX4 tweak and so far so good with the Brixus 6P. Thanks to everyone who put in the man hours to find way around this. Much appreciated =)

If bought from Google store, ask them for replacement.

If not bought from Google store, and if out of warranty, you are screwed.

[Nexus 6P General] aoaleman:
So after triple checking the edits and making sure they were all right, it looks like there might be something else that is needing to be edited in order for it to boot. This 8.1 dev preview boot looks like it panics and reboots straight back to the bootloader. Never gets to the bootanimation.
[Nexus 6P General] SlimSnoopOS:
They apparently have it working on the 5X so there's likely just a tweak that needs to be done for the 8.1 preview. Maybe ask OP below:

Nexus 5X thread with a different OP posting Oct and newer 4 core images. Do not flash anything there if you use Nexus 6P:

[Nexus 6P General] lovesara999:
not from google and its out of warranty :( how come some ppl successfuly resolved bootloop issue and some couldnt .

what's reason? im i missing anything ?
[Nexus 6P General] aoaleman:
Damn, what the! I compared the fstab and init.angler.rc files and they are identical! Maybe something in the bootcfg file? I'm not able to check right now in Linux. :/
[Nexus 6P General] DaKoin:
love your dedication

keep at it man, i'm sure a bunch of us here are eagerly awaiting. Last night i got up and flashed the 8.1 thinking i could use the 8.0 boot.img. i was sorely mistaken. lol
[Nexus 6P General] aoaleman:
Yep. Looks like something is definitely different with this 8.1 boot compared to Oreo October boot.
[Nexus 6P General] NoobInToto:
Or he could have moved on to another device, like me. Just got my pixel today.

---------- Post added at 03:04 AM ---------- Previous post was at 02:57 AM ----------

My theory is that some people are lucky enough to have the smaller 4 cores intact. The ones who cannot make it work have a device with the smaller 4 cores failed in the same fashion as the bigger ones.
[Nexus 6P General] lovesara999:
ok thanks for the information... does heating/freezing the phone will help ?
[Nexus 6P General] chris9000:
I was able to get the older July fix working. Are the 8.0 boot.img and the ElementalX kernel files in the first post compatible with the October Oreo build?

Which factory image is recommended? Think I'm getting a bootloop with the latest one...

Anyone got the 8.1 boot image working?
[MENTION=2004880]xls654[/MENTION] can you help us get the boot image working?
[Nexus 6P General] NoobInToto:
Heating/freezing the phone usually helps people boot in long enough to flip the OEM unlock toggle in developer settings. One user has claimed that applying heat/cold made his phone not bootloop for few days. However, I believe he was mistaken since that behaviour is only a symptom of the beginning stage of bootloop failure.

Ultimately, at some point after using the 4 core fix, your phone may fail permanently.

Hey darkriff/all - still bootlooped so want to run through the steps I took to make sure I did it correctly/should try something different.

Phone was 8.0 or 8.1 and bootlooping

Dev options disabled, was able to boot into phone via hair dryer and enable

Downloaded ABD/Fastboot

Downloaded 7.1.2 (N2G48B, Jul 2017) from dev.google

Extract contents (did not extract second zip)

Boot into bootload

ran cmd - fastboot flashing unlock, confirmed on phone to unlock

run flash-all.bat (took maybe 5-10 mins, no errors)

restart phone

flash boot N2G48B_4Cores.img

restart phone

still boot looping, have waited approx 30 mins.

Appreciate any help!

[Nexus 6P General] warnow:

[Nexus 6P General] NoobInToto:
Ex kernel is optional. However, if you want ex kernel, you cannot just flash ex kernel as a standalone fix( you could do that in nougat , but not in Oreo). So if you want to use ex kernel, you must have the modified 4core boot image.

If you are stuck in boot animation (not bootloop), then it is a sign that you need to wipe data.
