guys i have a simple question, i'm newbie xD

my phone was in bootloop and now he's back to work with android 8.1 and 4 cores boot and recovery isos

there is a way to use all the 6 cores or they are damaged? how to unbrick the phone completely and restore it to the normally like before? it's possible or impossible? it's a little bit laggy in games :S

thanks for the theard timbe <3 i love you and my phone too ahahah
[Nexus 5X General] :
I haven't done anything yet :highfive:

But yes your big cores are broken (if the cores were the problem in the first place)

You can try to overclock to make games smoother

January Security Updates.

Hi! I can see January update notification i my phone. Can I update it from OTA I received? It's 41MB in size, or do I need to wait for modified 4 core zip?

BTW, is there anyways to flash the ROM without loosing user data and account info while flashing the update I get from here? Because every time I flash and an update, I loose data and setup the phone again and again. it's frustrating. Thanks

---------- Post added at 05:35 PM ---------- Previous post was at 05:33 PM ----------

How can I update the modified files without loosing my data? when flashing it's all gone. Please help.
[Nexus 5X General] pixbuf:
I used the boot-4Core-bullhead-OPM1.171019.011.img from the Dec 2017 update and it worked fine. I will reflash when the Jan boot file is released.

To avoid losing all your data you can use a modified script that doesn't overwrite the /data partition. You have to unzip the image-bullhead-opm*.zip that's inside the factory image .zip file first. This is what I use:

The december image seems to work for me. However, I need to encrypt my phone but the modified bootloader prevents encryption. Does anyone have a solution of how to enable encryption ?

---------- Post added at 05:38 AM ---------- Previous post was at 05:33 AM ----------

It seems the january update file is the same name as December file and it does not work. Is there a wrong upload of file ? Thanks for all the hard work. this is really helpful.
[Nexus 5X General] :
For me it did boot. Yes I had to modify the December build as the tools weren't working with these images. Only changes were in the kernel and updated it in the image.

Maybe I uploaded wrong file. I will have a look

edit:

The link had a typo.

But I modified the official January image anyways with kitchen.
[Nexus 5X General] invrao:
Previously I tried with 4coreoreo and October image shown in the other post.. with TWRP and ex kernel..

After that my mobile was stood on for only half an hour or 1 hour.. later it's dead. I heated the motherboard and I can successfully enter TWRP for few minutes. Later it's completely dead. Charging was around 60%.

Today I tried with December stock firmware and and it's 4 core recovery and boot images shown in this thread.

First I flashed all images separately with fastboot commands and then restarted to boot loader and again flashed the modified boot and recovery..

Now Its started easily on reboot.. but I stayed only for 15 to 20 mins and switched off.

Now when I long press the power button.. it's turned on for one time.. stood for 5 mins and turned off.

Now Its not Turning on.. once I entered into recovery.. it's stock recovery.. May b it's the modified one given in the thread.

Is there anything to do to keep my Device on??

There's no TWRP in my phone now. No magisk installed.

Any help?
[Nexus 5X General] pixbuf:
No, it leaves everything untouched.

[MENTION=7802360]invrao[/MENTION]

If you flash-all.bat any of the factory images then reboot and flash the corresponding 4-core boot image your phone should boot and act normally.

Flashing (4-core stock/4-core Twrp) recovery is not necessary for your device to boot or act normally

If you intend to use recovery you can flash (4-core stock/4-core Twrp recovery)

If your device is not operating correctly after using these kinds of fixes then you may have a different hardware issue.

In your case it could be a failing battery.
[Nexus 5X General] invrao:
Thank you [MENTION=4548091]joenun[/MENTION]

While doing flash-all.bat it's showing an error that the boot.si , recovery.si ....... Is not found...

So I did flashing manually with fastboot commands

When the phone is in off condition, if I connect it to the system... it's showing 9008 under com's and ports.

Is my Device won't work??
[Nexus 5X General] :
Did you flash all the files properly? All the radio and bootloader files?

I can tomorrow make a one core image for testing. But it seems like it is not the blod error (not suitable for daily use). Or maybe you are doing something wrong
[Nexus 5X General] invrao:
Thank you [MENTION=7280252]T1mb3[/MENTION]

When I'm executing flash all.... it's not getting success. It's showing error that boot.si recovery.si ... So .. on.. files not found..

So I'm flashing stock images one by one

Boot,

Boot loader

Restarting Boot loader

System

Radio

Vendor

Then restarted to Boot loader and flashed modified 4core boot image

Then flashed modified 4core recovery and restarted device to system.

Stayed in on condition for few minutes for two or three times.. then blank...
[Nexus 5X General] :
What .si files? Did you download the zip from google and extract it?
[Nexus 5X General] invrao:
Yes.. I downloaded the files from Google developer website..

I didn't remember exactly.. it's .si or .Sig
[Nexus 5X General] :
You mean img.

Sounds like either your other hardware parts are dying or more cores are damaged
[Nexus 5X General] invrao:
It's not .img ...I'm sure about that.. it's other than .img starting with .s
[Nexus 5X General] mspasov:
when you flash through fastboot dont worry about .sig not found,the procedure will continue normally in a few minutes.
[Nexus 5X General] invrao:
Thank you [MENTION=7980562]mspasov[/MENTION]

I thought it as an error and closed every time., I tried.

Today I'll do in flash all method
[Nexus 5X General] joenun:
@ invrao yes at the beginning of flash it will sit a couple minutes then complete
[Nexus 5X General] invrao:
Thank you..

Is there any way to confirm whether it is the battery problem or hardware problem?

[Nexus 5X General] pkelly517:
You can still encrypt.

The flag just allows the device to run without encryption.
[Nexus 5X General] Addicted2Bass:
i still read that people are installing ex kernel, how? i keep getting back in loop after install..
[Nexus 5X General] TXKSSnapper:
Are you flashing over a custom rom or over stock android? I've been trying to figure out an issue I've had with modifying ex kernel, with no luck. The only way I've gotten it to work so far is to:

1. flash updated system image

2. flash stock modified kernel

3. boot phone

4. flash modified twrp

5. flash modified ex kernel

6. Sometimes I have had to wipe cache and dalvik cache also.

This probably won't work with any custom roms due to ramdisk changes, but may be an option if you just want stock with a 4core ex kernel.

Also to those who were asking for an update from me, my apologies I was far busier than I anticipated over the holidays. I am still trying to figure out why it isn't working, but have very limited time to do so.
[Nexus 5X General] Addicted2Bass:
yeah stock android i got the images from here, have 4core twrp.. i didnt do wipe

but in version 5 that was last one i tried, needed to set the speed of the big ones? i thought that the big ones are causing the blod
[Nexus 5X General] TXKSSnapper:
Those of us modifying are either lazy or don't know how to modify the actual install script. Just set the big cores to stock and continue to install. Those values should be ignored by the 4Core modification.

edit: I also recommend not overclocking the small cores, because I've had issues getting it to boot and stay booted consistently. For a couple of weeks I was only able to get ex kernel to boot if I underclocked the small cores, but I can't promise that will fix it.
[Nexus 5X General] Addicted2Bass:
phone didnt boot with big cores on stock.. lol so confusing haha, maybe for my phone better to do it with stock kernel
[Nexus 5X General] TXKSSnapper:
Sorry to hear that. :-/ Does it get stuck at the google logo or reboot into recovery? Just trying to see if its linked to the other issue I've been having.
[Nexus 5X General] Addicted2Bass:
it get stuck at google logo
[Nexus 5X General] ompo:
Thanks [MENTION=7280252]T1mb3[/MENTION] January image worked fine.

Only thing is that the device is noticeably slower - apps launch in about 3 seconds (WhatsApp, Inbox).
[Nexus 5X General] phaltu101:
In my case, it attempts to start encryption, gives the familiar logo and comes back in few seconds to home page. No encryption done. i got OTA firmware update today and that too did not apply saying your have corrupted bootloader. BTW, when I restart, it does show the bootloop screen saying your bootloader is corrupted. But then proceeds to boot anyway. Any pointers ?
[Nexus 5X General] joenun:
advice...be happy your bootlooped 5x is working :good:
[Nexus 5X General] NiceIce:
Same problem here with encryption not working on 8.1 Dec image. There's a green droid for a few seconds and then the device reboots straight into system.

I have to return the device for warranty so the encryption is important to secure erase all personal data.
[Nexus 5X General] joenun:
if you are sending in the the device then you can simply flash the corresponding stock boot image
[Nexus 5X General] sean878:
Thanks for the help in advance!

So, my phone got stuck in a boot loop :( then fixed using bootloop of death fix. Currently on patch OPR6.170623.023 and wanted to update but I am having trouble.

So far I have flashed boot.img file then I try to sideload the .zip file and I get a message of invalid zip signature. I tried with the stock recovery and with TWRP no luck, I am most likely skipping something. Also, do I have to do each update or can I just do the most recent?

Any help would be greatly appreciated.
[Nexus 5X General] Addicted2Bass:
maybe try installing the files from January update via Fastboot?
[Nexus 5X General] anjon111:
How to flash the system image? please help, I'm confused.
[Nexus 5X General] ted3:
Most common way is connect via USB to command prompt via ADB and fastboot flash boot.img
[Nexus 5X General] jd1639:
To flash the system image, the .zip file, you'll need to boot into recovery and then adb side load it. If you haven't installed adb and fastboot on your PC you'll need to do that. The boot.img is flashed using fastboot from your PC with your device booted into the bootloader, fastboot flash boot boot.img
[Nexus 5X General] simfyz:
I did try that method via Git Bash, but it did stuck the phone android boot screen. So flashed with flash all. I will try again on next update. Thank you for the tip.

[Nexus 5X General] pawitp:
Hi,

I have created a small Python script to automate the process of modifying the boot image to reduce the chance of human mistakes and also make it easier to apply the same fix to future versions.

You can find it at https://github.com/pawitp/nexus-5x-blod-fix

Feel free to use, take, modify, etc.
[Nexus 5X General] crazyates:
Does it make a difference if I use fastboot from my PC, or TWRP to apply the .img files? TWRP has the ability to flash .img, so I wiped everything (system, data, internal storage, everything), copied the files over, used TWRP to flash them onto the appropriate places, and it's still not booting.

I have the October Android O that I flashed from a factory image. I couldn't keep it from bootlooping, so I used the 4core workaround. However, I accidentally used the 4core in the original fix post for August's Android O release. So, it would go to the spinny circles, and that was it. Then I found this thread and since I already have the latest Android ) with no OTA's, I just flashed the boot image provided here. However, I am still getting the spinny circles. Any help is greatly appreciated !

---------- Post added at 08:43 PM ---------- Previous post was at 08:06 PM ----------

I did a factory reset and was able to get back in. However, does that take away the 4core fix?
[Nexus 5X General] truekasun:
I have never been flashing img files from TWRP but i guess it is same as flashing from PC. What version of the files did you flash into your device? October?
[Nexus 5X General] truekasun:
Glad you were able to get the device working again. No factory reset doesn't make any changes to the boot image. I have no idea why some people still getting the bootloop since I've tested these images on my device. Anyway thanks for the updates.
[Nexus 5X General] pawitp:
I originally only tested it using Python 2. I've fixed it so it also works on Python 3 now.
[Nexus 5X General] crazyates:
OPR4.170623.006 for all 3 files (system.img, 4 core boot.img, and vendor.img). I was already using the newest 4 core TWRP. Radio and Bootloader are also up to date.
[Nexus 5X General] truekasun:
That won't work since you need to flash all the stuff in the system image zip file including bootloader and radio. You better sideload it with adb rather flashing each img files.

OPR4.170623.006 is September update as I remember. Go with the latest (]OPR4.170623.009).
[Nexus 5X General] crazyates:
Well obviously when I said I flashed the system, I didn't just flash the zip. I extracted the zip and flashed all the .img files inside it. Radio, bootloader, system, and vendor. I used the 4 core boot from the OP, and the 4 core recovery (TWRP) from the other thread.

I just tried it again, re-downloading everything again and starting from scratch, making sure I was using the OPR4.170623.009 version of everything. I downloaded the stock firmware from Google, and used the .009 boot from the OP, and the TWRP from the first thread. Flashed everything from my PC via fastboot. Flashing went fine, and I can sit at the bootloader screen for hours. Even got into TWRP, and wiped everything before installing system/vendor/modified-boot.

The phone still freezes between 2-15 second after trying to boot the system. Most of the times it freezes within just a few seconds, during the boot animation. Sometimes I can see a flash of the lock screen, and then it freezes. I'm at my wits end, and I can't figure it out.

I'm so frustrated by this, I just ordered a Moto X4 from the Fi store. It'll take a few weeks to get by, but I got a data-only SIM I can put into my wife's old phone. Between a data-only SIM and being on Wifi all the time, and hangouts working on any device to text, I think I'll be fine for a little bit until the new phone gets in.

Unable to connect to ADB on bootloop

I'm trying to follow through the steps here, but my phone is not recognized by ADB. I have been trying to install (update) drivers via Device Managers but it does not work. I get "Device descriptor failed request" next to Unknown USB Device.

Is there any way I can install device drivers? My Nexus 5x is stuck in BLOD.

Would highly appreciate being pointed in the right direction

Thank you
[Nexus 5X General] truekasun:
Glad to hear you've get the update done successfully. But I do not provide the EX kernal and never used that on my device. The latest one is in the BLOD parent thread.
[Nexus 5X General] truekasun:
Well, I'm not clear what situation you are facing to. But adb is accessible when you are boot into the recovery and trying to sideload an update from adb.

If you boot your phone into the bootloader, then you got to use fastboot (which is similar to adb)

Just try to boot into the bootloader and type "fastboot devices" in the console on pc while the device is connected to the pc. So you'll see the device in the console if the device is successfully identified by the fastboot.

I guess you are trying to contact the device via adb when you have to contact it by fastboot. (Correct me if I'm wrong)

Good luck. :)
[Nexus 5X General] joenun:

[Nexus 5X General] Xandr0ss:
"fastboot devices" did work, and I am able to follow through steps 1-3.

Problem arises in step 4, I am unable to get to recovery menu to be able to sideload update-opr4.170623.009.zip. When I select recovery mode in bootloader, device goes back to boot loop.
[Nexus 5X General] truekasun:
Are you sure you flashed the recovery (Step 3 - fastboot flash recovery recovery-img-4core-opr4.170623.006.img) correctly?

When you choose to go to recovery and if it's rebooting, most probably something's wrong with the recovery flashing.

Try again with flashing recovery image again. If it doesn't work, try with older recovery from the original post.

Your bootloader is unlocked. Android Pay doesn't like that. The kernel needs to hide this.

Hi, I'm stuck with this problem cause I didn't unlocked the OEM before. There's a way to unlock it by ADB or something else to solve the problem? Thanks
[Nexus 5X General] :

You have to boot your device and enable oem unlocking.

You can try freezing or heating the device to get it booted for a few minutes.

Help needed

Hi everyone,

I was able to save my device using the boot img

(Jan 2018) , everything is working fine, the only problem is that I can't shutdown or restart my device, every time the device restarts or shutdown it's start bootlooping again and I have too flash the boot img to start it.

Is that something I have to live with? ( Making sure my Nexus won't ever shutdown?)

Tnx
[Nexus 5X General] :
Well, it shouldn't be. But if that current method won't work you can flash twrp and have a boot image in your storage that you can flash with twrp if I remember correctly.
[Nexus 5X General] Developert:
Tnx, i thought about trying that but I can't get into recovery mode as well. Everytime I try getting into recovery (TWRP) thrugh the bootloader it's just start bootlooping again. I'm pretty much depended on my computer to boot the phone. That's sucks but I guess it's better then nothing.
