I have an r800x with locked bootloader, 2.3.3. I have successfully rooted and installed CWM, and have used several ROMS, with my favorite being the UK Firmware version and Darkforest 3.0.5.
My question is, besides the ability to use custom kernels to overclock, would there be any real difference in performance or whatever running those on an unlocked bootloader versus a locked bootloader?
If the rom works on a locked bootloader, it's not going to be any better on an unlocked bootloader
So, with respect to the CDMA versions of the Play, unless you want to use a custom kernel for overclocking, or you want to run Cyanogenmod, there's no real reason to unlock the bootloader.

Yeah, pretty much. CDMA can't install GSM firmware with a locked bootloader though

Hi, in the development thread I saw a CWM for locked bootloaders. Would this mean that you can install 3rd party roms with a locked bootloader? I thought you need to unlock your bootloader to install 3rd party roms? What is the purpose of that CWM ROM for locked bootloaders?
TIA!

Some roms CAN work with a locked Bootloader look over at the old X10 forums.
With cwm, u can flash custom mod like the acid audio or pureXaudio even with a locked bootloader just like what I did on my xperia ZL. But current cwm for locked bootloader is buggy. Dont really recommend you to waste your installing it..
Currently there is no custom rom for XZL that support locked bootloader.

I've done some research in to unlocking the bootloader for my Xperia Arc. I have yet to understand the reason why you would need to unlock it at all.
The official definition given by Sony on their website is:
Unlocking the boot loader allows you to put custom ROMs on your device.

However this is clearly not true. As I am able to put custom ROMs on my Xperia Arc without unlocking the bootloader (ie. I was on official ICS firmware. I flashed kernel to different version then root using doomlord's ICS root, flash back the original kernel then installing Ultimate HD 4.0 via recovery.)
I have noticed some other ROMs state they are for unlocked bootloader only. Is this becuase they require custom kernals in order to function? Is that why you need unlocked bootloader (because locked bootloaders can only accept official kernals during flash/boot)? Or is there a more in-depth reason?

To explain further, you can still install custom ROMs, but only ROMs based on stock firmware and using stock kernel. If you tried to install other ROMs like CyanogenMod you will realise that you can't install the ROM at all because you cannot flash the custom kernel that comes with it. What the unlocked bootloader does is allow you to install unsigned kernels onto your phone. Stock kernels are already signed by Sony so they can be flashed without unlocking your bootloader.
The kernels you have been flashing so far are all stock kernels so you can flash them with no issues. If you tried to flash a CM kernel you will get an error if your bootloader is locked.

Thanks. So I was right. The Kernel is (one of?) the reason you would want to unlock your bootloader.
Do you know if unlocked bootloader is required for SD partitioning on Xperia Arc? I had a read here http://forum.xda-developers.com/showthread.php?t=2126363 but something is confusing:
- Unlocked Bootloader (need EXT4 support, not allowed in stock kernel)
- EXT4 Kernel Support (most of kernels for Xperia 2011 have EXT4 support)

It says stock kernel doesn't work then says most Xperia 2011 kernel support it?!?!

I see. So it's not possible to use link2sd without unlocked bootloader?
u dont really needed i payed 10 dollars to unlock it so i can use custom kernel to increase the performance of the phone,but still after 2 months after that i dont see any improvenments

Really? Went from Stock .587 rom to ultimate HD with stock .587 kernel and I find the phone can't handle more than 3 apps without slowing down at certain times.
I was actually considering unlocking so I can get an overclocked/custom kernel to improve performance.
What do you mean by after 2 months you don't see any improvements? Did the performance improve at first but now have gone back to similar performance of stock kernel?

If you don't know how to optimise the ROM then it will be as slow as any stock ROM. Don't say that the performance never improves after a certain time of usage. Please read up on the ways to optimize and improve ROM performance rather than assume that custom ROM is not good when you haven't tried optimizing it yet.

The base ROM is good, but it's the stock kernel giving the bad performance. Overclocking doesn't help much with performance so it's not recommended.
Like I said in my earlier reply, the ROM will work properly if you optimise it for performance, so don't say that the performance does not improve after a certain time of usage.

Correct me if I'm wrong but by saying "ROM will work properly if you optimise it for performance" do you mean flashing a custom kernel? (in which case you would need unlocked bootloader?)
Or do you mean an add-on like this: http://forum.xda-developers.com/showthread.php?t=1908269 ?
Or something else?
The only "optimizing" that u can do on a rom is removing the animations since overclocking is not recomenced.So i still find it useless.Even the phone app is starting slow.So in my opinion spenging money on unlocking ur bootloader is useless

So I tried "pimp my rom" and ticked all I thought I wanted but got a boot loop and had to reflash everything.
I'm keen to know what you mean by "optimising".

It can be as simple as installing and removing apps to running scripts that improve performance. I use Greenify to hibernate apps running in the background and I don't install Facebook on my phone. Only install apps that you use often because if you install many apps on your phone, it's going to take up more memory and slow it down.

Hey guys;
I have an Bell Sony Xperia ZL, rooted, but locked downloader.
I checked to see if I can unlock the bootloader to install CyanogenMod on it, but it says that it say 'No' for bootloader unlock allowed.
Does this mean that I'll never be able to unlock the bootloader and install CyanogenMod on it. I had a Samsung Galaxy Gio that I bought from Bell, and I could install Custom ROMs to my heart's content.
Any suggestions?

sorry to say but as far as i know if you won't be able to unlock the bootloader. On the upside, there are a few custom roms for locked bootloaders.

Rooting and installing CWM will allow you to install mods and custom roms made for locked bootloaders, it won't help to unlock the bootloader though.

Have a look here:

There are a few topics on how it is done depending on your version.
My Z1 compact is running and i am trying to unlock the bootloader. I have entered *#*#7378423#*# which says i cant unlock the bootloader.
Is there any other method to unlock the bootloader?
Anyone know if its possible?
The reason I want to do this is to install custom Roms.
Instead of unlocking, I believe its possible to root using root and then install dual recovery.
Is this possible and will it let me install custom Roms?
Your device seems to be branded by your carrier and there is no workaround.

Yes, but only stock based. CM based roms require a different kernel which can only be flashed with an unlocked bootloader. So your choices are quite limited. The good news: Sonys roms are pretty good. The only question is how long their support will last in the future.
Sorry mate, but with a Bootloader unlocked allowed status set to :NO you cannot install any custom ROMs. You may however still root the phone if getting rid of bloatware or installing apps that require root is what you are after

Not completely accurate, he can still install cooked roms based on stock, as long as they do not modify boot partition as he can only run stock kernels.
Hi everyone, I have a bit of experience with flashing roms to android phones from the past and I'm coming from an LG G3 that has Lineage OS installed on it.
What I'm looking to do is to get Lineage installed on my HTC 10, I picked it up the other day and it came shipped with Android 7.0 Nougat installed. I haven't got a clue what to do first just in case anything goes wrong.
So my questions are:
How do I unlock the bootloader and is there anything I need to do first? (What is S-Off?)
Can I flash TWRP without rooting the device to just nandroid backup?
How do I go from Stock rom to LineageOS via flashing? Is it just as simple as wiping system etc and flashing in twrp?
I'd urge you to read a lot more before jumping into this because your questions suggest you're really not aware of what you're doing. It helps to comprehend what each of these terms and actions means before you pull the trigger.
Check the 'development' section for how to unlock
S-Off enables you to update firmware separate from ROMs
No, you need to unlock the bootloader to be able to flash TWRP
Once you have unlocked the bootloader and flashed TWRP then yes, flashing a ROM is as easy, but referring to S-Off, you'll need to be sure that your firmware is compatible with the ROM of your choice; if not, you'll have to flash that separately.
Really. Read up. Check these guides first.

I know my fair share of android modifications and have done so in the past. It's just this is the most ive ever spent on a phone and I dont want to mess it up firstly. I've even compiled roms of my own in the past as you can see from my signature.

So, it's oem unlock, twrp, backup, and flash away? Reading up on S-off, it only seems useful for those that are doing really specific modding. I just want the ability to either root or flash custom roms so the bootloader unlock should do me fine right?

Yes, but if you want to flash a custom ROM not supported by your current firmware version, S-off will be necessary.

How do I know if a rom doesn't support my firmware version? Is that like flashing a CDMA ROM to a GSM phone (that level of difference) ?
Or is it like converting carrier firmware to stock HTC firmware?

Just check in the thread for the rom you want, installation requirements are usually listed there.
