Custom Roms - Nokia 7.2 Questions & Answers

So now that Nokia has made it impossible to unlock the bootloader, this pretty much sinks any custom rom development for this device, right?

Locked/Unlocked Benefits

Hello everyone, I have just received my beloved white X10a after letting a friend of mine borrow it for almost a year now. I know how to flash ROMS and know some (although very little) about Android tweaking and things like that. Coming back to the X10 forums it seems that the bootloader has finally been unlocked!
I have not unlocked it yet and I am running Donut 2.2 with XperiaS look along with ThKernel 2.6.29. I am enjoying the smoothness and average battery life (this battery is super old so I imagine that it's lasting capabilities have diminished a little). Anyway, I don't use my X10 for much, just a few games like Draw Something, but mostly I like reading manga or e-books and forums. I edit a good bit of pictures as well.
So, what I want to know is am I going to benefit from unlocking my bootloader? I know unlocking it allows so much more control over your phone but since there are not many devs still here in the X10 forums, is it even worth it? Will I benefit from anything by using kernels for unlocked bootloaders with my phone usage? I have never overclocked a phone because I really had no need for it but is it safe to use an overclock-capable kernel but use the native voltage at all times?
Hey pal yeah it is basically as u said there a few nice kernels about now with oc, built in recoveries (xrec, cwm and bootmenu-kernel booting) and many other tweaks and things. Its well worth doin as with flashtool its so easy to do it just one button. There are kernels for locked bl i think but dont know if they as good never used one (i unlocked as soon as the laser released it) id say personally do it

Locked bootloaders allows you to have custom kernels too, but they're not as advanced as the custom kernels for unlocked bootloaders. If you have a custom kernel that you have in mind to use and it has specific patches/fixes/additions that's only for unlocked bootloader (which you need), you should unlock your bootloader.
Plus, some ROMs requires you to have unlocked bootloaders (i.e. FXP CM7/CM9) as they require their own custom kernels (which has patches/fixes/additions that can only be used/made/added with unlocked bootloaders).
Furthermore, with unlocked bootloader, it allows you to use BOTH custom kernels which were designed for locked and unlocked bootloader thanks to D's BootMan (but you still need to use the recommended kernel for the ROM that you're going to use).
Give it sometime, think about it. Once you've decided, take your action. And make sure to test your USB connection first as if they're broken, you might ended up getting your USB disconnected while in the process of unlocked bootloader (which will result in bricking the phone).
I really appreciate the insight guys.

Custom ROMs for locked bootloader/stock kernel

Hi!
I would like to ask whether there are some really nice custom ROMs for locked bootloader / stock kernel. (Yes, I really don't want to void my warranty.) If anyone knows one, please share a link here. Thanks!
If you really want a custom rom without unlocking bootloader and for stock kernel :
Ask SONY to make one for you because ONLY SONY/official firmware can be install for locked bootloader or firmware that are sign by SONY (mean custom firmware that SONY certificate only)
If you really want custom rom badly,why don't sacrifice your warranty for something that you like?
Custom ROM removes your warranty also.
You could try THIS one... it's a mod, not a custom ROM. This is the best you can get without unlocking the bootloader.

Locked Bootloader

Sorry is this question is stupid, but I just got my Maxx, and I'm a bit confused about the locked bootlader. How do you guys flash roms? What exactly does the locked BL mean?
There are root exploits for the Razr. That allows you to install a custom recovery and flash ROMs. Unfortunately the locked bootloader means no custom kernels. The kernel is the building block of the OS. All the cool under-the-hood stuff is in the kernel. So basically without a unlocked bootloader custom ROMs are more of a glorified theme. Obviously there is more to a ROM than just the Theme but that's as simple as I could explain it.
Also it is important to note that with a locked bootloader it is very important to know what you are doing and read instructions thoroughly. If you mess up it can be a huge headache to correct it. As with a locked bootloader some mistakes can be irreversible

Unlockable bootloader + Custom ROM question

Hey all, first of all I'm not new to the Android world. I've had many phones, and all if them modified heavily. I do not consider myself a Dev (I've made some basic scripts that's about all) but definitely a power user.
Anyway, I'm a little lost on this z2 as far as modding it goes. My bootloader is NOT unlockable according to the phone stats, however I have seen a few root methods for 5.1.1 and locked bootloaders (I'm build a.1.232). Now many of these rooting methods ask for you to downgrade to a rootable version, root it, then reflash a prerooted 5.xx ROM. Easy, However with my unlockable bootloader how will I flash anything other than a stock Sony ROM without bricking it?
Essentially what I'm after is how far can I go with a locked bootloader, and if there is s surefire way to root 5.1.1 without downgrading since I can't flash back up. Also am I good to flash a custom recovery? Or is that offlimits as well being locked. I'm a little lost due to lots of mods here apparently working with locked bootloaders, and on my HTC one that just didn't fly.. Lol.
Thank

You meant locked bootloader right?
You won't be able to flash any custom ROMs without unlocking your bootloader.
The only custom ROM that works for locked bootloader is MIUI (which uses the stock Sony kernel)and the phone needs to be downgraded to 4.4.4 and there are some custom ROMs out there which may work on locked bootloaders.
Yes,you will be able to flash custom recovery and use mods that are available on XDA and also xposed works fine on LB
You won't be able to flash custom kernel or custom ROM for LB
Yes downgrade is possible

Couple of questions (Noobie Alert Warning)

Hello, I am super new to xda and to phone rooting. I've recently got a Xiamoni Redmi Note 4 and I really want to root it to unlock the FULL potential of my phone. I'll keep the rest of this thread short by asking:
1. Does MIUI Version matter? I am currently on Global 8.5 l Stable 8.5.4.0 (MCFMIED) Android Version 7.0 NRD90M I am also on a snapdragon
2. Once I unlock my bootloader, is the bootloader unlocked for good?
3. Where can I find a systemless root guide for my phone? (FOR SNAPDRAGON)
4. What are custom roms exactly? What would you suggest?
1) IDK if MIUI version seriously matters but I'd highly recommend to update it to the latest stable.
2) Bootloader is locked for the security of phones, for common users. For further read, see this.
3) Search for "Magisk". You'll VERY easily find the guide and everything you need.
4) Custom ROM is technically an OS. Very usually they're just different flavors of Android. When you flash a custom rom in your phone you're basically changing the phone's OS. You usually get the benefit of getting a smoother, clutter-free phone with a custom rom, well obviously there're risks which you know (or can google).

Nope. I can't tell anything beside these facts. Nice reply. Only that I'd suggest avoiding miui roms and once rooted, flashing of a pure, aosp based Rom.
