The bold underlined text is slightly confusing me.
I know from previous experience that the bootloader unlock is necessary for root/modifying stuff.
I am assuming that you mean you do not recommend re-locking bootloader and critical.
However, it sounds like you are saying that you do NOT recommend unlocking bootloader and critical.
I read it like this:
3. Bootloader unlocked: words words words. I dont recommend this, as there are lots of bricks from messing up a flash and locking yourself out afterward.
4. Critical partition unlocked: word words words. I dont recommend this, as there are lots of bricks from messing up a flash and locking yourself out afterward.

Am I correct with assuming that it is not recommended to re-lock bootloader and critical? Leave them both unlocked.
First day with my PH-1. I am probably over reading everything right now. Sorry for being an idiot.

I read that thread and still not sure if me being on a custom kernel affects anything. I supposed I would flash the stock 8.1 ROM and the kernel would be stock again?
Then relock? Wanted a couple opinions before I go doing this

Don't quote me on this... I'm thinking the bootloader and the critical partition need to be unlocked to flash a kernel(??).
Though, if I'm following you correctly, I think you may have the intention to perform the two lock commands after you've went back to stock + custom kernel. Those two commands (I think) erase internal storage anyway. I'm not sure, myself, if they act as the standard wipe in twrp.
Maybe grab, or try to grab the OP of that threads attention. He or She seems very helpful.

I just did OTA to p from stock 8.1 with custom kernel and locked BL with no issues. Was kinda surprised as Google phones fail with OTA if not on stock.

[ROOT] CWM Test 8/Flashable SuperSU

As discovered in the Q&A post found here: http://forum.xda-developers.com/moto-x-2014/help/root-t2886674/page2
Just like the first Moto X, users have been having success rooting by unlocking the bootloader and just flashing SuperSU with CWM. This is a test release so it may be wise just just boot to CWM to flash SuperSU instead of flash it. Use caution as always.
Bootloader Unlock Guide: http://forum.xda-developers.com/moto-x-2014/general/guide-unlock-bootloader-moto-x-2014-t2876773
CWM Test 8: http://d-h.st/XJr
SuperSU flashable ZIP: http://forum.xda-developers.com/showthread.php?t=1538053
I can report that this did work for me and I have achieved root.
Steps I took:
1. Unlock bootloader using Motorola's website
2. boot to bootloader, flash or boot to recovery with fastboot command (fastboot flash recovery cwm.img/fastboot boot cwm.img) *There really isn't a reason to flash this. It is very broken. Consider keeping your original recovery!*
3. boot to cwm and flash superSU zip
4. CWM will prompt to fix root, choose YES
5. Rooted!
Almost everything besides flashing a zip is broken in this CWM release, don't expect to be able to backup with it.

I appreciate you posting this, could you by any chance post a little bit more detail on how to do the flash? Is it as simple as extracting the recovery image and flashing from ADB? How do you then flash SuperSU?

I added some basic steps to original post, use caution as this isn't the most secure way to root but it will do for now. If you need further help, you should probably wait for a safer method.

What are the gaps in security? When you say secure, do you mean safe as in not bricking the phone or security as in data is at risk, etc.?

the steps you listed are pretty much it. can't get any easier than that. exactly how it was on the previous MotoX. unlock bootloader, fastboot flash recovery .img. then just reboot to recovery and flash SuperSU zip. very straight forward.
edit: also, fix permissions shouldn't be required...

It was just mentioned in the original post, I guess it doesn't matter. And by not secure I mean that the CWM is a test release so I don't know what could go wrong.

yeah i'm still awaiting a device so i'm not 100% sure on the persmissions. the zip should do all the work for the user, though, via the update-binary.
btw thanks for posting.
Thanks for posting this, I suggested the guys in Q&A to do that. If anybody needs help, I made the process successfully back on Q&A (when they were testing the recovery)
If anyone notices the permissions making a difference let me know, I'm curious as to why everyone was saying it had to be done..

I apologize, I did not realize if you are just booting, you don't need the "recovery" part of that command. Glad it worked for you!
You mention that this version of CWM is limited to basically sideband loading and won't do backup. Do you happen to know where I can find a copy of CWM for the X 2014 that gives me shell access? I've already unlocked and rooted my phone, but busted my screen and want to back things up. I went to their rom manager page and can't find either version of the X. Would either a 6.0.5.1 or one of the Nexus ones work?

Locked bootloader & No OS | What could be done?

Hi all,
I'd been using my rooted Nexus 6P on stock ROM+kernel. Unfortunately, I locked the bootloader after installing TWRP and installing SuperSU. I know, it was a huge mistake but it happened.
Yesterday I wanted to unroot and factory reset the phone. I forgot that my bootloader was locked so I didn't flick that "enable oem unlocking" button. I tried "flash-all" directly on bootloader. Obviously it didn't work and after reboot it got stuck on Google screen. I waited for a while but nothing happened. I wiped system, vendor, cache... etc on TWRP upon a tutorial in this forum with the intention to flash stock ROM but again : my bootloader was locked.
Now, I can still use TWRP and push files through adb but cannot use any fastboot commands. I get this error:
Code:
FAILED (remote: device is locked. Cannot flash images)
I tried installing the whole "image-angler-mdb08l" on TWRP but I get this error:
Code:
Updating partition details...
...done
Full SELinux support is present.
MTP Enabled
Installing '/sdcard/image-angler-mdb08l.zip'...
Checking for MD5 file...
Skipping MD5 check: no MD5 file found
E:Could not find 'META-INF/com/google/android/update-binary' in the zip file.
Error flashing zip image-angler-mdb08l.zip'
Updating partition details...
...done
Is there any way to flash stock ROM with TWRP or should I try flashing a custom ROM and hoping to boot so I can enable that troublesome OEM unlock switch?
Compared to similar situations in 6P forum, I have the advantage of working adb and TWRP but I don't know if they even make a difference. Thanks for sparing time to read and your help.
You cannot flash factory image with TWRP. Download any custom ROM, flash it with TWRP. Let it boot and enable unlock in Developer Options.

You restored my faith in saving this phone. Is there any custom ROM in particular that won't mess with the recovery partition? It seems that if I loose TWRP, I have nothing to hold on to.

I believe that CyanogenMod wouldn't corrupt TWRP recovery. I've flashed official CM on my Galaxy S4 so many times, and CM never replace TWRP with something else. ????

Your guide is amazing and helped a lot.
I had been using N5 with locked bootloader and never encountered any problem but when I switched to 6P I read some articles explaining how dangerous leaving the bootloader unlocked is, so I locked it. Obviously, it was a mistake. I'm glad I didn't have to RMA.

There is risk in involved in having an unlocked bootloader, but as long as you take care of your phone and don't let it fall into the wrong hands you'll be perfectly fine. To say it's dangerous would be a pretty big overstatement.

Updates through custom recovery with a locked bootloader possible?

If I locked my bootloader, can I update SuperSU (zip) or TWRP (img) using TWRP --> Install?
I'm already aware that it won't allow me to flash custom ROMs, custom recoveries or use fastboot commands.
What does having a locked bootloader prevent me from doing?
Thank you

The better question is why would you have a locked bootloader? If you have any kind of boot loop or error you will end up with a paper weight that will have to be sent off for repairs when its easily fixed with an unlocked bootloader.

You're right about having a boot loop problem but isn't the phone more secure with a locked bootloader though? I read that it's recommended that you relock the bootloader if you're done making modifications so that no one can do anything malicious with your phone (to some extent).

I would say it's much more likely you brick your phone due to having a locked bootloader than someone else getting their hands on your phone and actually having the knowledge to cause trouble for you.
to relock your bootloader you must have FULLY STOCK firmware back on your device, relocking with anything in the phone being custom can result in a paperweight
Having a rooted phone is more vulnerable than a unlocked bl phone. Dont lock bl back unless you are full stock (I would still say dont though)

It's more secure, sure. But if you take care of your phone it doesn't fall into the wrong hands. Plus, if you have TWRP installed still a tech savvy thief (one who understands what a locked bootloader means) can easily flash a ROM and boot into the phone. As sometime else pointed out, the chances of you ending up with a brick are higher than the chances of someone getting your phone.

Ok that makes sense to not lock the bootloader. Thanks for the information everyone!

[V29a only] I managed to relock the bootloader without any backups.

While using the v29a ROM, @kessaras said it should be possible to lock the bootloader using "fastboot oem lock", which didn't work for me on any ROM. I decided to give it a try anyways and it actually worked! It wiped my data, and after restoring and all that I rebooted the phone to see if it was actually locked. "fastboot getvar unlocked" gave me a result of "no". Try it out, but beware, your data will be lost. Proof video: https://youtu.be/Tr6E9LaGWRs Before doing this make sure EVERYTHING is stock! This includes custom recoveries. I do not claim any responsibility if anything goes wrong!
Steps (assuming you already have v29 rom installed):
1. Download ADB and fastboot, along with LG drivers (if you don't have them). Connect your phone and start CMD. CD to the folder where your adb and fastboot files are. (pretty obvious isn't it? )
2. Type "adb reboot bootloader".
3. Type "fastboot oem lock". This WILL wipe your data, and I'm NOT responsible for it!
4. Enjoy your locked phone.
Interesting to say the least, is there any drm locked content that you now can use? (not sure if g4 has any)
Tbh you can relock even without loosing data (at least on LL and MM).
Just reflash the misc partition from either a previous backup (recommended) or from a extracted stock kdz partition will do so.
You should backup misc and the persistent partition before doing so just for the case.
Never written it down because I thought its something no one would like to do but that's verified to work...

Didn't see you mention flashing misc partition. But if I don't remember wrong it gets flashed everytime we install a KDZ with LGUP anyways this method should be somewhat safer as it doesn't involve flashing anything.

no - not every partition u see in a KDZ will be flashed.
Especially when you have an unlocked bootloader.
well the fastboot command will erase all data. flashing misc not nvm i don't care about which is better just wanted to add that there is a method which works on LL and MM (fastboot command will not work there).
btw you should consider to add a [N only] or similar in the thread title

I don't care either, now the good thing is that we suddenly got from 1 method involving backups to 3 methods of which 2 don't involve backups. Hurray :highfive:

Sorry, don't know how to help you here. I read about this error snd supposedly after 10 seconds this message should go away by its own... Try to boot it and wait a little. Then unlock back the bootloader with the unlock.bin and flash the stock recovery from the ZIP file of V29a (which should've flashed by itself, did you remove it?) and only then lock the bootloader. Make sure everything is stock.

Well, I guess you hard bricked your phone. You had modified firmware(TWRP, kernel) and relocked. Not even surprised you're phone is bricked. Only shot would be send it to LG but they will 99% know you messed with firmware

Freshly bought Mi A1 - to OTA or not to OTA?

Hey guys,
want to mod my freshly bought Mi A1 to the max, but I'm not sure if i should OTA first or better start modding right away?
I already unlocked the bootloader and it didnt wipe it - it also has 7.1 installed still. Generally I'm usually reluctant to do official updates because they usually make modding harder - but I tried booting the treble TWRP installer .img through fastboot (without installing it) and it failed because some partition was missing it said.. so I just want to hear if OTA is necessary to use the latest custom roms or if i can keep the old bootloader etc?
Would be cool if someone who knows could say smth about that.
Or is updating through OTA actually recommended even when not planning to ever use stock roms?

If security matters for you yes
The only thing you'll share with a custom ROM is the bootloader
Since may update locking or relocking the bootloader will wipe your data
It's your choice
but it will still work as easy as before to unlock/lock with just a fastboot command, right?
and will a custom rom work with a locked bootloader? Like first unlock, install custom rom + kernel, then relock?

It will always be that easy to unlock and relock the bootloader
No don't relock on anything that is out of stock (custom kernel , magisk, custom ROM etc) this will lead to a softbrick and you'll have to be on edl more to reflash a stock rom
What's the interest of having a locked bootloader with a custom ROM? You won't pass the safety net anyway
Just keep it unlock
You can do ota with an unlocked bootloader

What's the use of your android one device if you will not update it, that's what you pay for.

hahahaaa exactly the point :laugh:
well once you have everything "perfectly set up" updates can ruin it. but yea relocking the bootloader really was a stupid idea - it was the idea to make it tamper proof but since custom kernels wont boot with locked bootloader that wouldnt work.
