If you can run a custom kernel on P900; does that mean the boot loader is unlocked?
Sent from my Jasmine Note 3
Sorta? If you are running a custom kernel you had to unlock the boot loader to flash it in something like twrp. You unlock it to install a custom recovery. The bootloader contains instructions to boot the kernel and such. If you have root or twrp on it, it is unlocked.
My note 3 is locked (Verizon). I can run custom roms but not kernels.

We can do both freely and easily.
I guess I should get one of these instead of nexus 9 as there are too many issues with the nexus. Thanks.

I'm on the latest official OTA of 4.2.1
Do I need to unlock the bootloader to root?
I read this http://forum.xda-developers.com/showthread.php?t=2187982
and I'm still not sure whats happening... Do I need to downgrade to root, and do I need to unlock the bootloader to flash TWRP?
I know a bit of what I'm doing as I have rooted and flashed roms on an htc desire and a samsung s2x (t989).
On 4.2.1 theres the occasional hiccup and freezes when I use chrome... Is this still an issue in the custom roms? Also my Settings app crashes when I try to load the "Running" tab in the apps section of settings lol
Can someone point me in the right direct?

Well, you have two basic options:
Get root without unlocking.
That is good, if you want to stick with stock ROM, but want to run Apps that need root access.
Or if you don't want to unlock for any reason.
More details in this thread: [JB ROOT] motochopper works! (Root JB 4.1.1 & 4.2.1 with locked bootloader!)
Unlock and install the patched TWRP for -4.2.
This will allow you to root stock ROM easily or you can install custom ROMs.
Be careful: You have the boot loader 4.2, which means you need to pick the patched TWRP for that boot loader and you need to pick one of the ROMs supporting the 4.2 boot loader.
People have bricked their TF300Ts not using the patched TWRP -4.2 version.
There are currently only two ROMs available, but more should be coming soon, as Asus has finally released the new kernel source code.
If your preferred custom ROM supports only the 4.1 boot loader, you need to downgrade. Or just wait a little, as you like...

No and yes.
You can use the tool from the tread above just get root; no downgrading, no unlocking.
But yes, if you want to install TWRP, you need to unlock your device first.
You only need to downgrade for installing a custom ROM that does not (yet) support the 4.2 boot loader.

I have not used stock ROM for a while, but generally people report that most custom ROMs run much smoother than stock Asus ROM:
I would suggest downgrading ti the 4.1.1 bootloader, as there is a much larger variety or ROMS available.

Thanks was a lot of great information! I rooted my pad and did a few speed optimization things such as re-trimming and now its much smoother! Maybe I'll try a custom rom later but as for now, I'm happy with the updates that Asus provides

I'll keep that in mind but I believe there should be more soon as f69m, stated that asus release the kernel for 4.2
I signed that petition in your signature as well
I'd say go for the 'full experience'. Having an unlocked device also allows you to reflash ROMs at will and can also help in a pinch when it comes to backups/restores. Also, if you happen to lose root, it's easily re-rootable through the bootloader.
I'd just be careful of the current TWRP 4.2.1 recovery blob. I just flashed the one released this morning and I am currently getting this weird double screen thing. Best bet is to sit tight at the moment; an update should be out shortly.

Well, stay away from the TWRP 2.5.0.0-4.2 provided in some thread today, but TWRP 2.4.4.0-4.2 should still be working fine.

1 is there a version of CyanogenMod for the S6
2 if so does screen mirroring work with CyanogenMod on it. (i have a note 8 and it has CM12.1 and screenmirroring dont work to chromecast.)

1-no.
2-no.
That sucks how do you unlock the boot loader if possible. or does chainfires auto-root do this for you

For lock bootloader you have flashify if you want to install samthing or flash a rom.
Ya but the bootloader needs to be unlocked to root the phone how do you unlock the bootloader
Many variants you don't. Many have locked bootloaders with no unlocks available.
Since we have gotten no updates or way of OEM unlocking, wouldn't it be possible to request SONY for the Linux Kernel source (spirit of the GNU GPL) of this handset and build a ROM using it just to get past the bootloader?
I am thinking about this in terms of the Amazon Fire tablet that is bootloader locked but somehow got a working CM 12 (or was it 13... can't remember).
ROM is different from kernel, you don't build ROMs from kernels.... and you won't be able to flash a custom kernel without an unlocked bootloader unfortunately.
if its oem locked, what about to flash global rom for ur phone and then proceed from there? as far as i know global roms are not lockedd so strictly
Hi,
I have purchased a Galaxy S8+ Verizon version, I want to know if I could install custom ROMs on it from the stock galaxy s8+ page. I am a little confused about this as I want to try out different ROMs, Also will installing different ROMs unlock the device?
Thanks
LOL. You purchased the wrong device if you wanted custom ROMs. You can only flash stock official ROMs via Odin on the North American Snapdragon S8. There is no unlock for us.
All you can do is root it: https://forum.xda-developers.com/galaxy-s8/development/samsung-galaxy-s8-root-snapdragon-t3659305
Maybe??

So I understand that the bootloader verification and lock is why we can install TWRP, but I swear on my Razr(XT912) or Bionic or G3 had a locked bootloader but they had a way to boot the ROM after initial boot you would have a way to boot the regular system or boot to custom Rom. Killing me right now what name of it was, is it just that there was an exploit or is the security much stricter

It was probably exploit like safestrap No exploits have been found obviously for our devices yet
Hello,
Is there any development arround custom Bootloaders on OP6?
Meaning not unlocked, but custom, so I can boot the kernel in EL2 mode.
thanks!
