As I don't hale enough posts to ask this in Development section under ROM trend, I'm creating new one.
So I used ViperX for a long time, but now I'm back to stock and also restored DRM keys. I've notced, that you can flash Marshmallow Concept without unlocking Bootloader. So why ViperX need to have unlocked BL? In fact it's just rooted Concept with some addons. Isn't it possible to install XZDualRecovery and then flash ViperX through this? Can anybody explain this to me?

Its not that easy bro xD
To make it short its because bootloader, if you re-lock it you need get invited or flash stock otas, which will mean no recovery (only the stock sony one, you cant Flash stuff only signed otas from sony) also you dont have no root in /system so you cant modify it.
If you unlock it your able to Flash a custum kernel which contains recovery, that means also that you can use customized roms, such as normal root and modify all partition, also you can get twrp recovery.
If you want all answered, read Sony Concept Initiative Thread from jenkins-84 on the last 10 sites theres allmost all your question answered.
Peace

I just got a W8 with a battery date of 11W51. So I can no safely unlock the bootloader without paying someone, something I do not want to do. I read the development forum and was about to root and install xRecovery. Now I would like to install a custom ROM. Am I able to do that without an unlocked bootloader?
Yes.
You may install a custom rom without unlocking bootloader.(only those one which require stock kernel).

Is there anyway to be sure a custom ROM requires stock kernel if it doesn't say so on the title or the thread?

Hi there guys!
I want to root my Z1 c6906, unlock the bootloader and flash custom roms, but im kind of confused right now because i have read a lot of different guides and im not pretty sure which one to follow now. I also learned on one thread that i should do a TA and DRM Keys backup because they can be lost forever if i don't do a backup. Also the IMEI. So im not pretty sure how to do that. Also saw a thread about bricking the device, and kind of got scared. Btw, i have plenty of experience working on Android devices, unlocking, rooting, flashing roms, etc. I have used Android since the G1, but im kind of confused right now about how to proceed on this device because this is my first Sony and my last phone was a Nexus 4, which was virtually unbrickable. Can anyone help me out here?

Quite simple process actually, just flash .534 ftf with flashtool and root with bin4ry or use nuts dual recovery installer. To backup your ta before unlocking bootloader, simply use the Backup TA tool

Sorry for bringing back this thread. Now i got time to start trying to unlock the phone and flash custom roms, was extremely busy before with work.
New problem: After i downgraded to FTF .534, rooted and made the TA Backup, i check if the phone was "allowed" to be unlocked and surprise, it says it can't be unlocked. Tried unlocking with Flashtool and it said the same thing. Can the phone be unlocked or is there a way to flash roms without unlocking?
Right now im feeling really depressed with this phone. If i can't unlock it, i most likely will sell it and get something that can be unlocked.
One of the reasons i want to unlock is because on 4.4, Google prohibited the phone to write on the Ext.SD and i want a way to overcome that prohibition and use it like i was able to on 4.3.
If it says it cannot be unlocked then it cannot be unlocked
However, you can still sort out the issue of writing to the ext SDcard by rooting and following the instructions in this thread
http://forum.xda-developers.com/showthread.php?t=2687966
In order to do that, you only need root, not to be unlocked

Ok. That sucks. Thanks for the link.
Another question: How i root.757? I was able to root .534, but not sure how i need to proceed now. Do i need to download generic .757 and apply any root method? Or the root will still be there if i flash it over my current rooted .534?
1) Flash a stock 534 FTF (Ignore if you are already on 534)
2) Install dual recovery (Find files and instructions in the XZ dual recovery thread in the cross device development section)
3) Flash a prerooted 757 rom (Find files and instructions in the development section)
Done, 3 easy steps

So i can flash any rom now with that recovery? Even if my bootloader is still unlocked? Or only stock based roms?

If your bootloader is unlocked you can flash any rom from the development sections or the original development section
But if your bootloader is unlocked you do not need to do any of this to root.
Just flash DooMKerneL or [NUT]s XZDR kernel
If your bootloader is locked, you have to downgrade and root that way. Then you can flash any stock based rom, look in the development section for them

Hi all.
I was a big xda user / developer around the times of x8 / x10.
Things have changed alot
I've now got Xperia sp and is rooted via towelroot and Installed the recoveries. Bootloader is still locked and I am on stock everything
I NEED help. Can I flash a custom rom. Really want to but not.sure.if this will brick my phone. So here I am asking.for help
Thanks in advance and.if.you help I'll be clicking your thanks button.
Thanks again
Yes you can install custom roms, head over the roms zone and find the ones that in their names says "LB" which means Locked bootloader, the ones that say "UBL" are for unlocked bootloader and if the roms says both it means they work on both locked and unlocked bootloader

Thanks again
Where is thanks button gone?
Also can I flash rom just like I use to
Download on my phone put in sd card boot to recovery then.flash
Going.to go for it soon will keep you informed what roms I try etc
Found the thanks button.
Need more help before I will flash a rom if you can pal?

Please do me a favour and have a look at that
Can I install it I have root via towelroot and have recoveries installed and.the same build number 12.1.a.1.205?
Yes you can, that rom is for both LB and UBL, and thanks alot mate! i've been browsing xda for a long time now but never had a chance or didn't want to make an account, but oh well, anyway's.. i think there might be better roms for you to try, that one seems like it won't get any more updates..
Also, there's cm, paranoid, pac-man for Locked bootloader, you can take a look on them too
Just make a backup of your current rom in case you want to go back
And sorry for the late reply, wasn't at home!
What about the build number do I have to find one same as my.stock build number.
Nah, anyways, there's a FTF thread that has stock firmwares to download in case you want to flash stock firmware via FlashTools

Why not flash a pre rooted rom and keep your bootloader intact. Slim 1.3 has a good following and Wajk is a committed developer
Destroying your TA partition just so you can get onto the latest (bug ridden & problematic) deployment seems a bit extreme.
Edit: if you already have MM installed then you will need to follow bilboa1's great guide on how to back up your TA partition and root
This will mean downgrading your rom to an older version, then rooting, then adding recovery, then flashing a MM build with root built in.
It's a long process but non destructive, you'll get to the magical MM but with bootloader intact.

Thank you, one question though, you said that the bootloader will be intact, what about the drm keys? i've read that the DRM keys might go even if the bootloader is locked!

If you take the time to read the thread linked thread above, you'll see that it shows you how to care for your DRM keys so that they can be restored in the event of something untoward happening.
There is an encrypted partition (TA) on your phone that has your personal DRM keys, unique to your phone, they can't be replaced with anyone elses. To open you phone up to a custom kernel or a CM build rom you have to overwrite this encrypted partition, or unlock the bootloader.
Once you have used the old rom exploit to root the phone, you can flash any stock rom without fear. Stock roms are designed to work with the TA partition and pushing a stock rom onto your phone will not damage your DRM keys. That's why I said unlocking the bootloader is a big deal, not to be done just to root a phone. There are less damaging ways to get to an MM build, with all your camera functions intact.

so if i want to root but still keep my DRM keys i must use my phone with stock roms only? that's fair

I just would like to add that you don't have to keep stock roms (like the pre-rooted stock roms) but also stock based custom roms, for example SliMM (http://forum.xda-developers.com/z3-compact/development/rom-slimm-t3359831). There are probably more stock based custom roms but SliMM is probably the only one that is being actively developed. I use it daily and love it.

Yes. Sorry for basically repeating your post, I just wanted to make it a little bit more clear for him, that there is a difference between stock based custom rom and a custom rom
to tell you the truth, i didn't know that slimm rom was a custom rom, i thought it was a stock rom with "more features"
If you don't know what root is etc I suggest you do some research on it before just jumping in without knowing anything about it ?

First of all, first post here so hello everyone and thanks for having me
My issue is the following, I have a C6906 which I bought a couple of years ago from Ancel (one of the carriers here in Uruguay) and it has always had a branded 4.3 (14.2.A.1.136 to be precise) which has never been updated by Ancel (the version listed in XperiFirm is the same I have and my phone has never offered an OTA update). I asked Ancel about this recently to see if I could expect any official updates and was basically told "yeah, that's not happening".
So what I would like to do is upgrade the phone to Lollipop by myself, namely to 14.6.A.1.236 from the US which seems to be the most current and generic stock available. Rooting and custom ROMs are (at this point) not something I'm looking at.
So I read a bunch of stuff and I think I'm "ready" to do my upgrade, but before messing around with my phone, I wanted to have somebody else more knowledgeable check my plan and give me a couple of pointers so I avoid any snafus as much as possible
Right now I have Flashtool (0.9.21.0), XperiFirm (4.9.1) and I've used it to download/unpack the ROM I think I want (C6906_Customized US_1276-7484_14.6.A.1.236_R2D), so my questions are:
1) Are there any glaring mistakes in the tools/approach described above?
2) Since I'm doing stock -> stock, can I perform the flash/upgrade without unlocking my bootloader? As I understand it, the bootloader checks for the installed ROM signature and I would expect the new one to also be signed by Sony, but I don't know if the signature also includes my carrier (and that's why I haven't been offered an upgrade yet).
3) If the answer to 1 is negative (i.e. I have to unlock my bootloader anyway), is there any advantage in going for stock instead of some other custom ROMs? As I understand it, unlocking the bootloader removes DRM keys that might kill some functionality (like "advanced" camera algorithms), would that happen for both stock and custom ROMs?
Thanks a lot in advance for any replies/pointers :fingers-crossed:
You don't need to unlock bootloader to flash stock ROM. Unlocking is need if you want a custom kernel which is not your case. Anyway you can backup your DRM keys and use that to lock/unlock your bootloader whenever you want to. See here http://forum.xda-developers.com/showthread.php?t=2292598
Thanks... Just to confirm something else, if I try to flash without unlocking the bootloader, there's no chance the version I'm installing won't work right? If it's not a properly signed version the locked bootloader will prevent Flashtool from putting it on the phone?
