Hello.
I am currently looking to buy this phone and flash a custom os, if someone could please answer them that would be great:
1) After unlocking and locking does the phone go back to Widevine L1?
2) How easy is it to unlock the phone's bootloader (is it as simple as fastboot oem unlock or similar?) and how hard is it to lock the phone's bootloader (is it as easy as fastboot oem lock?)
3) Do most custom OS's support Widevine L1?
4) If I lock the bootloader whilst having a custom OS how hard is it to flash back the stock OS?
Looking forward for replies.
Hey there!
1. I am currently rooted and it still says Widevine L1 (checked with DRM Info app).
2. I don't think there's a phone that has easier bootloader unlocking/locking.
3. The Zephyrus custom ROM, which I currently use has Widevine L1 support. I don't know about other roms.
4. Haven't done that personally, I know GrapheneOS recommends locking the bootloader for better security, but I am pretty sure it doesn't have to be permanent, and it should be fairly easy to go back to the stock firmware. Just remember not to lock the bootloader while rooted, as that would brick your device and it probably wouldn't be easy to fix.

Ok so I was reading an article and now I'm confused. I see there are two ways to unlock a phone...the regular unlock command and an unlock critical command. From what I understand the unlock critical command is for updating the bootloader? When would I want to do this? I was on the Android P final beta and because official Pie release was delayed here in Canada I decided to just unlock and flash Pie manually. I did this and then relocked the bootloader. But is my bootloader outdated now? Confused. ?
If you keep the bootloader unlocked your bootloader will never go out of date, otherwise the bootloader will not be updated on subsequent stock ROM updates. I personally recommend unlocking the bootloader using both commands and keeping it unlocked. You'll have a minor annoyance in that you'll have a warning pop up prior to boot about the bootloader being unlocked, but I believe avoid a major annoyance in Factory Reset Protection being disabled with the bootloader unlock.
Ok. So just unlock using both commands? Do I just enter in right after the other? How does the bootloader get updated?
Also does leaving the bootloader unlocked stop Google Pay and some banking apps from working?
Enter both commands, one after the other. The bootloader, even if it has no updates, is included with every copy of the stock ROM you download from Google. It will also be included with any OTAs that come directly to the device. You'll have to discover for yourself whether Google Pay and your banking app are affected, because I simply do not know. I don't use my device for banking.

Certainly you can if you are prepared for a bricked device later. I mean, it is not advisable to lock the bootloader if you have a custom ROM since any issues arise later, you will not be able to solve them. In addition, even if you manage to unlock the bootloader again in such a scenario, you will lose all your data including files, photos, videos etc.
If you properly sign the firmware, you don't even have to unlock the bootloader, see https://forum.xda-developers.com/oneplus-3t/how-to/guide-custom-kernels-roms-recoveries-t3572525
Hi,
Long story short:
is it possible to install customROM without root and to (re)lock the bootloader, and are there experiences with a similar situation where Apps check for closed bootloader and root (and stop working if detected)?
=> Goal: activate WiFi-Calling as my provider tuned down 2G-transmitpower due to the 5G-advances (without having enough 3G-coverage to make calls on UMTS-net)... BUT: I'm using two banks; one uses a PhotoTAN-App, that stops working if it detects an open Bootloader, the other Bank-App checks for Root & open Bootloader, and likewise stops working if detected. I have no idea about the PhotoTAN and Magisk, but the 2nd bank confirmed they checked rooted devices with Magisk, and that it does not work with it....
Thus, if I go for a CustomROM, I need to be sure that I can run it unrooted and with a locked bootloader....
Is there a way to install a CustomROM on the 5X with (re)locked bootloader and without root?
(or, if not possible: is there a way I can activate WiFi-Calling on StockROM if said one does not have the Carrier-Entitlements?)
Thanks for the help
@theunlucky: you don't need root to flash a custom ROM, only an unlocked bootloader. IMO you can lock it after flashing ROM.

Are you sure about locking the bootloader after flashing a CustomROM? I've read several threads now, and it seems a locked BL only works with StockROM?
Not sure, therefore IMO IMO a locked BL prevents flashing CustomROM, not running. Try. If it doesn't work, you unlock BL again (triggers factory reset). In the worst case you've to flash latest firmware for a clean base..
I'm looking to unlock my bootloader to try and install gcam following this: technobuzz.net/ google-camera-without-root/ however I've never unlocked bootloader before and every time I go to I get put off by the warning messages...
Sooo I wanted to know if i unlock bootloader, enable Camera2 API and install gcam could I still lock bootloader afterwards or will it reverse everything?
is it worth it? or should i be worried about malware.. I don't intend to use roms ect.. I'd just like a fairly decent camera..
Also does anyone have any experience with Pokemon Go working with unlocked bootloader?
Thanks for any help.x
You have to flash fastboot ROM to relock bootloader and this will erase everything
Say you have enabled camera2api and kept unlocked bootloader, whenever you get new update build.prop will overwritten with original build.prop so you will loose camera2api
Hi! Does anyone know how to lock the bootloader?
Previously, I experimented with installing GSI (PixelExperience, Havok OS, etc.). But as it turned out, the original system is much more stable than the GSI (although I may not have found the correct GSI
I want to return the phone to the state it was before unlocking the bootloader. That is, now I have the bootloader in the "unlocked" state. And I want it to be "blocked". Thus, the phone will be almost in its original form.
