Hello,
I'm in a rather peculiar situation. I bought a Nexus 5X from eBay recently (I know) which was advertised as having the common bootloop issue, of which I saw there seems to be a fix for. After receiving the phone I found that not only does it bootloop, but the bootloader is still locked and the previous owner has set up the phone and used a PIN lock on the lockscreen, leaving me unable to get into the settings to enable Developer settings and unlock the bootloader. Does anyone know of any kind of fix for this? Just to reiterate, I cannot flash any stock rom, and there is no custom recovery on the device. I am not new to unlocking bootloaders and flashing custom firmware, and I have contacted the previous owner to no avail. Any help in this issue would be greatly appreciated.
I have searched the forums but as my situation is compounded of multiple problems (locked BL, no custom recovery and PIN lock) I feel like I have hit a dead end.
I am with ya
I have the exact situation i would love to know if you have figured it out. i have two of them as a package deal from ebay. Both 5x.
advertised as bootloop. wont go past the google screen.. one them i actually got to fire up but then ran into the pin thing...
Can you get in fastboot mode ? If so, you can try flashing a custom recovery

Hi guys I got the lollipop OTA for my nexus ( completely stock), never tinkered with it and the OTA installed but now its stuck on "google" screen and constantly bootloops. I have done some reading and I tried to unlock bootloader via Wugfresh toolkit and normal fastboot oem method but no avail, it gets stuck on the "yes" option.
Basically I have a locked bootloader which fails to unlock, and nexus stuck in google logo, any guidance will be much appreciated. Plz point me towards the right direction. :crying:
Try to unlock the bootloader from adb with OEM unlock command. The steps are posted above the factory images on Google's dev site.
yeah I tried that and tablet gets stuck on the yes option at unlock bootloader screen and nothing happens for 20 minutes , i have to restart it. I've read around and it seems like my emmc might have corrupted. Any pointers?

Well I can only think of one thing. Buy a new nexus. There aren't any listings for the Wi-Fi version and the LTE on Swappa. However there is some other devices on Swappa.
I unlocked my bootloader several months ago, but now my SIM card readers (both of them) have gone out. I have no idea how, no water damage or anything like that has happened. They just stopped working. So I went complete stock firmware, locked bootloader, everything but I am still unable to take OTA updates like a new phone would be able to. I think this is because they banned my device from OTAs which I believe they do if you have messed with the device. I need to RMA my device so my question is would it be better to say that I didn't tamper with the device and run the risk of them finding out I did, which is pretty likely seeing as how my device has been banned from OTA updates, or tell them that I did unlock it and all of that but that I have relocked it and I am back to stock? If any of you have had a similar issue how did ASUS handle that? Thanks!

Since I am a new user I cannot post links. But Google "Zenfone 2 bootloader unlock" and I followed the instructions of Grekky's Blog.
there is no such thing as relocking the bootloader. only thing you can do it flash the stock image to make it look stock (since an unlocked bootloader has a white splash screen) but im sure asus knows of this and will still check and see that the bootloader is indeed unlocked and not warranty it.
This is just something we all accepted as a consequence of unlocking our bootloaders. hell i have a screen thats getting worse and worse with a yellow/brownish line coming from the top of the phone, but alas i have an unlocked phone too.
You can replace the white splash screen by flashing a black splash screen image to try and cover up unlocking your bootloader. http://forum.xda-developers.com/zenfone2/themes-apps/551-black-white-splashscreen-twrp-flash-t3141945 . If the reseller has no clue about custom recoveries and trying to flash a rom you'll be safe.
They fixed it, no questions asked. And yes, I was able to relock the bootloader.
Hi everyone. My device just came back from lg, and apparently I've got a brand new mother board. There is a problem though: my rpmb is gone (fastboot states "no rpmb" right next to the secure boot string), and I guess that is what makes my device fail to unlock its bootloader. Now, doing a little searching on the net, what I get is that really little people also encountered this problem, and ALL of them seem to have sent their device to lg from Italy (as have I). Have I got any chance to fix it? Or maybe just take it back to lg for a check? What could I possibly say to them?
Note that I know pretty well how to unlock bootloaders under normal circumstances, as I have already unlocked many nexus devices of mine in the past, so that is not the problem.
Hey there! I found a solution to get root access, here's my post on Reddit about it:

Hope this helps!
Hello guys am basically a Noob when it comes to the new android 6.0+ security system that google included which changed the bootloader unlocking and rooting process a lil bit from the standert ( fastboot oem unlock ... fastboot flash twrp ... flash super su and voila )
let's get to my probleme with my nexus 5x when i unlocked the bootloader with the tool the device has to reboot but everytime i reboot i have to unlock my bootloader again the root works fine but the bootloader keeps getting locked everytime ... problem is that i messed with the boot img in order to disable forced encryption and now i can't flash stock because during the flashing the bootloader has to reboot and gets locked which make the flashing fails ... am on android nougat 7.0 if that matter and if someone have the 6.0.1 (mtc20k) boot image for noforce encrypte please share with me and thanks
You can update manually by flashing the different parts separately using fastboot commands. That way you can skip rebooting after flashing bootloadet

I have the same problem. Bootloader gets relocked every time i reboot. Could not install cm14.1, i just get i bootloop (tried with latest twrp and vendor). Went back to stock with the seperate fastboot commands. It works but really annoying that the bootloader wont stay locked. It worked before i sent the phone to service (emmc problem) and got the motherboard changed. Is there a problem with the bootloader or is it a hardware problem?
Sounds like a HW problem, RMA it again.

Thanks!
Yeah thats what im thinking too. But what do i claim as the issue? Is a non unlockable bootloader a warranty issue? Bought it unlocked from a store.

Ask Google (you can open up a chat with them for example on https://support.google.com/nexus/answer/4582729?hl=en&ref_topic=6023296#contact=1 or other links), for me it's a clear issue, you have the right to unlock the bootloader, however not sure how to demonstrate a problem if you bought it on a store...
All phones that come back from service do so in that state. Seems it's a decision from LG. If you go to bootloader you'll probably see that is says "no rpmb" right after secure boot. This is what is causing the issue, from what I know it is because a certain portion is not flashed on the motherboard replacement
The same happend to me, e-mailed the service center asking why they did this but they never reply

Hi, phone from my friend is in a bootloop, stuck on google logo. Phone is in the service now but I have a question, I was searching different guides for a fix and they all require unlocked bootloader but phone is locked and you need to Enable OEM Unlock in developer settings which is not possible atm.
But my question is this, why does nexus 5x requires unlocked bootloader if I want to reflash factory image ? Isn't locked bootloader only if you want to flash custom software, did I miss something with nexus 5x ? I am using Oneplus One so i am not sure what's the thing with nexus. I found basic guide to reflash factory image and in one of the steps it says bootloader needs to be unlocked.
Because the factory image cannot fix the problem. You will need a custom kernel which disable the big cores.
In order to unlock bootloader, you can heat up your phone (using a hairdrier) to boot temporarily. Google with "nexus 5x bootloop hair dryer".
