[Q] Locked Boot Loader, Can I Still Install ROMs? - Xperia Z3 Q&A, Help & Troubleshooting

So I had to downgrade from 5.0.2 in order to install KK+Root+SU But is it possible to install ROMs if the boot loader is locked? God, this sounds like a very silly question. If anybody could shed some light on my lack of knowledge I'd be very grateful.

With a locked boot you cannot install anything that relies on a custom kernel. So no CM, AOSP, BP, DU AOKP etc....
Basically, you can only install stock (i.e sony xperia stock) based ROMs

Thanks for such a quick reply. Definitely what I didn't want to hear, but that is something I'll have to live with. :/
Would you happen to,have any advice on how I can got back to Lollipop or download custom stock based roms?

ohhhh....... so that means even a locked bootloader is of no use to stop devs from making new custom ROMS? Yay!
Even more... there is a project 2ndboot that allows to boot custom kernel everytime.. but it not finished yet.

Hope it finishes soon!!
To put it better: it's not finished yet for our XT720.
On Defy it works good.
Nope! In Defy works 2ndinit! I was talking about 2ndboot.
I needed to clarify a thing..is it possible to flash stock based ROM for eg: [SE TWEAKED 0.85] in se arc s without unlocking bootloader..Im on rooted ,locked bootloader se arc s.
THANKS IN ADVANCE..
I don't know how similar the Sony Erickson phones are to Motorola. 2nd-init would likely work, but it would be better to ask in a SE sub forum.
Thank u so much dude....im sorry to have posted it here..

[Q] Need Rom that can Overclock.

Okay guys hear me out, sorry if this is in the wrong section of the forums, I'm currently rooted on the stock build I believe, my specs are as follows: Build Number: JROO3C.WW_epad-10.4.2.13-20120907. Android Version: 4.1.1. I rooted to remove bloatware, and whatnot, but now I want to overclock, and it can't be done with the kernal I have I guess, Stock rom doesn't support it, So I'm on a quest to find a working rom for my build that has been tested and working properly, I have the TWRP recovery I think it's called. And if you haven't guessed my device is Asus TF300T. Any help would be greatly appreciated. I'll be around waiting for a response, so if you need any other question answered or need more info I'll be around, Thanks for all the help.

SO your TF300T is unlocked ?
Apparently, you have the TWRP recovery.
And you want a rom that can overclock ?
So you have several roms, but the best you can do, it's to click to my sig > index for the TF300t, and you will find all roms based on stock and others based on Cyanogen.
The best thing that you can do is to read a little, choose 2 or 3 roms that you find interesting, and try one after one (one week per rom) and you will choose the best rom for you. It will be your choice.

Yes it's unlocked,and thanks, going to try the Hydro rom I suppose. Are the Cyanogen roms compatible with what I'm running? TWRP and Stock JB?

Hydro ROM does not have CPU OC, I think jb blue and [email protected] has overclock. Latest CM 10 is compatible with jellybean boot loader and latest TWRP.

Custom kernel for MIUI v5

Hello everyone. Is there a kernel compatible with miui v5? I want the swipe2wake option because official one does not have it.
If there is, I flash it via recovery or?
And, is there a high chance of bricking my DS when flashing a custom kernel?
Thanks

I think that actually is THERE, but the link is dead and dont know what features it includes. And flashing kernel is actually safe, maybe some bootloops or bugs if somethings mess up.

[Q] ROM's and Rooting

Hi This might be a question that has been answered already or no. I've been browsing through the site and ready on ROM's and stuff. I just wanted to ask how to identify if a Custom rom is stable already and if there is a way to know without trying the rom first. I am scared of rooting my phone because I am afraid that I might brick my phone and if so is there different ways or just a standard way to do like S-off/S-On and flashing a rom.
Phone: HTC Sensation
ROM: Stock ICS Rom 4.0.3

To identify the custom rom you need to flash it yourself and then judge it .But most of the JB rom like viperS/revelation especially Sense 5 is the latest and stable one ..
Also Before rooting and flashing custom rom you need to first Unlock bootloader and then flash recovery after that rooting and flashing roms..
No need to S-OFF , you will find it difficult (Wire Trick).
A great guide can be found HERE just skip the HBoot-S-OFF part and follow other instruction ..

Thanks for the Guide. Just a question though. Does this guide apply on all ROM's like those made by VIPER and those CM10 thingy.

Yes the guide is one time process.After that just download any Rom (VIPER or CM10 ) and then flash through recovery ..

Sorry for having such a lot of questions. Any particular Rom you would suggest. I just use basic stuff like gmail, txtplus app, and some games. A black based design would be perfect. Thanks in advance for the suggestion.

Bootloader Unlock Not Allowed, any way to install a different rom that bypasses this?

Hello guys, is there any way to install a more recent version than android 4.4 without having bootloader unlock allowed? I really want to play Pokemon Go and sadly it doesn't work on stock rom and my bootloader unlock is not allowed...
I'm really really noob at this, never changed a rom on any device before, so some pointers would be really appreciated! Such as how to install and which roms might work!
Thank you!
