[Nexus 5X Q&A, Help & Troubleshooting] moonlightdrive:
Hi, basicly i have a theory: the bootloop issue on the Nexus 5x mainboard is the same as G4.

On the LG G4 you can disable the BIG cores (cpu 4 and 5) and your phone will boot (even ultra bootlooped). I try this on a friend's phone (5x with infinite bootloop) and this worked, but now the big cores works too, so we dont know if this "possible fix" did something or its just a placebo effect and the bootloop issue on this device is due to something different.

I modified the ElementalX 1.20 Kernel (by flar2) just a little and now your phone will boot only with his A53 4 cores running (littles). so basicly it disables the big cores (2 A57) and lets the phone BOOT "aparently it works" (in that case that's where bad welding is).

Installation:

Flash oficial factory image 6.0.1 MTC20K (or any marshmallow stock build compatible with elementalx 1.20).

Method 1:

Download: Elemental by flar 2 modified for ILAPO.zip (12.76 MB).

Enter TWRP.

Download and flash the zip file and go trough the installation process normally (via Aroma

it does not matter if you configure the second cluster freq, anyway the big cores will be disabled).

Reboot system.

Method 2: (Recommended)

Download: bootelx1.20.zip (12.05 MB).

Extract the .IMG file. and put it inside your ADB's program root folder.

Enter to FASTBOOT mode.

Open Minimal ABD and Fastboot (or the ADB/fastboot client that you want).

With your pone into BL (and connected via USB to the pc) run:

Now your bigs cores should be disabled.

It only works for unlocked BL.

Please, try this and leave your comment.

OP can just post the boot.img instead or you can run the script on a working phone then back up the boot partition which can then be flashed on the bad phone using fastboot flash boot.

my phone havent got bootloop yet but nice to have this modify kernel

Thank you.
[Nexus 5X Q&A, Help & Troubleshooting] mcerk02:
OK, So the phone will work but you will have no use of the "big" cores? or am I reading this wrong? How does this effect the performance of the phone? My 5X is working fine so far but just getting some knowledge just in case....
[Nexus 5X Q&A, Help & Troubleshooting] AnrgKrshn:
Yes, no, and yes. The kernel just disables them through software, so performance DOES take a hit, although I doubt it is by a lot.
[Nexus 5X Q&A, Help & Troubleshooting] moonlightdrive:
Like [MENTION=4833911]AnrgKrshn[/MENTION] says you will not notice a very high loss of performance on your device for common and simple tasks (use of Chrome, Facebook, Whatsapp) disabling the two A57 'aka BIG' cores. I dont know where do you live but here in my country (Argentina,) the temperature oscillates now (almost summer) between 25 celsius degrees and 31c, and the thermal throttling -on stock Google kernel- starts working when it reaches 44c (the CPU) and this shut down the big cores or put them to work in 633mhz (almost idle) and the phone really runs smoothly even throttled, so you will not notice "The change", but for heavy games i think that you will do notice this.

[Nexus 5X Q&A, Help & Troubleshooting] RusherDude:
Guys RMA the phone, it's a hardware problem, complain Google about it. LG is even giving out full refunds..
[Nexus 5X Q&A, Help & Troubleshooting] moonlightdrive:
Yes, you are right. But only in the countrys where the device was sold officialy (us and some few countrys from europe). Lot of us are really fu...d up, since we have not rma :(.

I was cheated by LG and bootloop ghost twice (mi g4 bootlooped) my 5x still not but... Again on the same boat.
[Nexus 5X Q&A, Help & Troubleshooting] RusherDude:
Damn that sux, didn't think about that :(, I am sorry. I hope the OP solution works for you guys.

I was in the bootlooping situation weeks ago, and I know how hard that sucks!! right now I am stuck on recovery thanks to failed multi stage mecanism for full otas when sideloading hahaha. Google is soooo bad lately.
[Nexus 5X Q&A, Help & Troubleshooting] moonlightdrive:
Just incredible...

I thought this phone was going to be a better experience that the nexus 5 was, but I was wrong, now I'm seeing which device to get, this su***.
[Nexus 5X Q&A, Help & Troubleshooting] RusherDude:
Yep, I am right now using my old Nexus 5 which hasn't failed me at any point, and it's laughting at the N5X debacle.
[Nexus 5X Q&A, Help & Troubleshooting] AnrgKrshn:
Funny to read this, cause I know for a fact that the Nexus 5 had a very widespread power button issue that would result in random shutdowns and being unable to turn on the phone. The repair would require a new motherboard (at least that's what they told us in India) and was largely not covered by the warranty.
[Nexus 5X Q&A, Help & Troubleshooting] dontqq:
I tried following OP's instructions but my phone is still failing to even stay booted in recovery. Many times it does not even make it to recovery.

$ fastboot flash boot bootelx1.20.img
target reported max download size of 536870912 bytes
sending 'boot' (13636 KB)...
OKAY [ 0.386s]
writing 'boot'...
OKAY [ 0.634s]
finished. total time: 1.020s
$ fastboot reboot

Freezing helped some (i.e. I would occasionally have a few minutes of recovery usage before it would restart), but I hoped this fix would allow me to recover some data. Unfortunately, after performing the above, the phone still won't consistently stay in recovery. Any other options to try before I perform some surgery with a hair dryer?
[Nexus 5X Q&A, Help & Troubleshooting] moonlightdrive:
It seems that exists two kind of this bootloop issue caused by differents components:

EMMC (bad solders)

CPU chipset (bad solders too)

The yours looks like the first one (emmc). The only temp solution is to put your device inside a ziploc plastic bag (something airtight) and leave it in the freezeer for max 15 mins. If this does not work you can do "the surgery" with a hair dryer or a heat gun.
[Nexus 5X Q&A, Help & Troubleshooting] dontqq:
Ok, thanks for clarifying. Will go after the eMMC as per https://www.ifixit.com/Teardown/Nexus+5X+Teardown/51318#s112144. Basing my plan on something like http://xdaforums.com/showpost.php?p=69841935&postcount=40, which seems to be similar to other advice found on the internet.
[Nexus 5X Q&A, Help & Troubleshooting] moonlightdrive:
Yes, that will work probably, al these methods are attempts to be something similar to a reflow. The deffinitive solution would be a reballing (too expensive, and not very much people can do that because the size of the components)

Anyway i think that hair dryer method will work, good luck! And comment if works.
[Nexus 5X Q&A, Help & Troubleshooting] icyerasor:
My nexus5x suddenly died 5 days ago (with no prior symptoms). Unlocked, no root, stock 7.0 november update.

I was able to turn it on once for ~3hrs after walking outside for 20 minutes, right after it first froze down/bootlooped.

Then it showed up as "QHSUSB_BULK" (8009?) when connected to a pc, but would not even start fastboot anymore.

I tried putting it in the freezer in a plastic bag for ~10 minutes. Fastboot worked, booting freezed inbetween; twrp would not let me enter security pattern.

So I let it rest for two days. Then decided to give it one more try by putting it on my radiator for 20 minutes (just warm, not hot! - please don't panic and make the situation even worse!)

Got it to boot up regularly and keep it on for ~20 minutes. So was able to do one last backup of msgs, imgs, etc. (while still on the radiator). Booted up successfully two more times, but with every decreasing on-time.

RMAing now through Google.
[Nexus 5X Q&A, Help & Troubleshooting] aaronrw:
I've done the hair dryer method but once phone reached high temp it would loop. So I let it loop until it finally boots up(may be several hours) device gets super hot. Throw it in the freezer until it gets cold and stays booted long enough to enable battery saver. Worked for me for 12 hours so far coming from a state in which device was unable to pass Google logo.

I've tried everything i could, since i'm in Argentina (bought it on US Google Store) and can't get Google to issue an RMA for me. 16GB version, manufactured on October 2015, same happened to a 32gb also October 2015 my cousin bought. So i'm on my way to Thailand and probably getting a new phone there (not LG, of course) but if this could save my Nexus 5x i could get it back up and running and have it as a secondary phone in case something happens to my main one. Please advise me if it's worth a shot!

Halfway there

Well , I tried this out since I wasn't getting anywhere with my expired warranty , and surprisingly my phone managed to get to the boot animation , but did not boot at first , instead I realized the boot animation was running VERY slowly , so I waited and in about 20 minutes my phone managed to boot after 2 days , but that was it , after about 40 mins of usage I was back to the main issue at hand which was the bootlooping , but this time the phone did not just get stuck at the google logo but goes to the google boot animation everytime , and manages to boot once in a while , keep in mind , its taking a lot of time . So using this method I was able to get SOMEWHERE and I am hoping if anyone can help me out from here on. :):)

Mi nexus 5X is death

Not work on my Nexus 5X H791 (32GB). My phone is a piece of crap. Very angry with LG :( and disappointing with google :_( Thanks for the help moonlightdrive.
[Nexus 5X Q&A, Help & Troubleshooting] moonlightdrive:
My phone finally bootloops too. It was from March of 2016, lasted exactly a year. The only thing that i really loved about the 5x was his amazing camera and design (i know its cheap plastic, but had his nice looking style).

The performance of the SD808 al least in my case, really disappointed me (i think that the SD800 is actually better), It was always throttling and idling big cores due to how fast gets hot (above 45° Celsius) with simple tasks (i had to do a homemade "improvement" to fix this).

Now i bought (when the LG masterpiece bootlooped) a Moto G4 Plus, so, i really do not miss many features from the 5x, the camera in the G4+ (not the standard version) is a little bit superior (i take better pictures on low light scenes), and counts with laser and PDAF focus technology, has a fingerprint scanner too (and LOT of faster than the Nexus). But i miss the USB C feature and obviously the fact of being a "Nexus".

I can understand your angry, i felt the same, not going to buy LG never again, that for sure. We weren't the only "victims", look this.
[Nexus 5X Q&A, Help & Troubleshooting] Astatinium:
Tried this and i could get to the colored circles more times. To get to it to past the Google logo without this was pretty hard and only in some situations like: too hot (big cores are disabled), too cold or low battery (big cores disabled). Anyway, i tried to flash this with the recommended metheod but it doesn't get past the colored circles animation and actually that animation seems to lag a loot like it was having a FPS drop but still locked at 60 fps (just like some games for pc nowadays) and then bootloops again when it gets really laggy. I'm using 7.1.2 which is the latest Nougat build.

I sadly can't RMA my Nexus 5X because it started to show some signs of water on the screen and i decided to clean it with alcohol because i saw on the internet that it was the best way to clean a smartphone - im not doing it ever again. LDIs got pink. Even though LDIs can be "tricked" i think there is a way to know the smartphone has been open without authorization - IDK, maybe not.

How do you disable the cores with the newer kernels?
[Nexus 5X Q&A, Help & Troubleshooting] moonlightdrive:
If you want, upload the boot.img that you want to boot without the big cores enabled, i'll modify it.

But i need that you upload the file, since i am not on my house for a while, and i am using mobile data plan for connecting my laptop to the net.

Specify from what factory image the kernel belongs, so i can upload the modified boot.img to the OP, for these who want to try it on newer kernels.
[Nexus 5X Q&A, Help & Troubleshooting] 1982malex:
I can't attach files in this reply. I'm currently using N2G47W with ElementalX 4.09.

I tried modifying it with Image Kitchen under split_img in the img-cmdline.

I changed boot_cpus=0-5 to boot_cpus=0-3, like the kernels you attached, but according to CPU-Z it didn't stick for some reason.
[Nexus 5X Q&A, Help & Troubleshooting] moonlightdrive:
I am assuming that the boot.img from the build 'N2G47W' has the file "init.bullhead.rc" in the ramdisk folder. Open it, and search for the line that says "on boot" or similar, if you have it, you will find something like:

[B]on boot[/B]
symlink /dev/block/platform/soc.0/f9824900.sdhci /dev/block/bootdevice

# execute script to set [B]initial CPU settings[/B]
# don't run as a service to avoid race conditions
exec - root root system -- /system/bin/init.bullhead.power.sh

[B]# update foreground cpuset now that processors are up
write /dev/cpuset/foreground/cpus [COLOR="Red"]0-5[/COLOR]
write /dev/cpuset/foreground/boost/cpus [COLOR="Red"]4-5[/COLOR]
write /dev/cpuset/background/cpus 0
write /dev/cpuset/system-background/cpus 0-3

[/B]

change it to:

# update foreground cpuset now that processors are up
write /dev/cpuset/foreground/cpus [B]0-3
[/B] write /dev/cpuset/foreground/boost/cpus [B]2-3[/B]
write /dev/cpuset/background/cpus [B]0[/B]
write /dev/cpuset/system-background/cpus [B]0-3[/B]

In the best case this should disable the A57 cores (big cluster) all the time, but if not, they will be disabled at least during boot, leting you disable the cores manually from an app like EX manager.

Hope this can help you.

[Nexus 5X Q&A, Help & Troubleshooting] moonlightdrive:
That's so strange, you can't brick a phone by flashing a modified kernel, in the worst scenario it will be not able to boot correctly showing a message like 'failed to load kernel', or directly, stay in a bootloop state.

The bootloader/aboot remains untouched (if you only flash a boot.img into the boot partition).

Maybe you typed: fastboot flash bootloader boot.img instead of fastboot flash boot boot.img?

I will recommend you to flash the .TOT file using the LG repair tool.

Here is my original post:

I have had a galaxy s5 for 2 years, and noticed over time things have become slow.

With multiple apps I had to use some tools to get these to run from the SD card VIA app.

Seems that 16 GB of room isn't that much when you keep adding (some apps take up 2 GB)

I am also enjoy custom rom, recovery, root.

Here is the current ones I am looking at and my concerns.

Honor 8:

Concerned about speed and if enough of an upgrade

LeEco Le Pro3:

Concerned about development and lack of SD

OnePlus 3T:

Development and lack of SD

HTC 10 :

Concerned about 32 GB internal

Go for development and SD card supported devices

My suggestion to go for

any phone with good development and SD card support

.

Take devices without SD card if internal is >64 GB

. Sad thing is most of flagship phones won't come with SD card slot. Here are some good devices ,

1) One Plus 3T [128GB] (No SD slot)

2) MI 5s [128GB] (No SD slot)

3) MI 5s Plus [128GB] (No SD slot)

4) Asus Zenfone 3 Deluxe [64GB / SD card slot] (Lack of development)

That is definitely a problem I am running into . Not sure why they do not include an SD card

Same goes with removable battery . Maybe its a thing of the past.

From what I have seen from development and power , right now I am leaning towards the HTC 10.

It does only have 32 internal is the only problem , but with the SD it makes up for it.
