Evening XDA,
I have recently got this phone but unfortunately it has a locked bootloader.
Are there any ROMs I can install on locked bootloader? E.g. stock based.
How can I tell if a ROM is safe to flash?
I'm pretty sure that you can only flash ROMS through a custom recovery (CWM, TWRP) and to be able to get in your recovery you need boot loader unlocked. Unlocking it and getting a custom recovery isn't hard though and it comes with bonuses like making nandroids?. And regarding the safety of ROMs I recommend downloading from places that look official. Just Google what ROMs there are for your phone and choose what sounds best (cyanogenmod is pretty good?)

That's wrong, you don't need to unlock bootloader in order to install a custom recovery. Rooting the phone is enough. Then the correct install file from Nut's database and you have more than one recovery.
"Z1C-lockeddualrecovery2.7.XXX-BETA.installer.zip (XX.XXMB)" would be your choice after rooting. More information HERE.

This is correct. I have already rooted and installed recovery on my locked bootloader device. :good:
I cannot unlock my bootloader, unfortunately I get "Bootloader unlock allowed: no"

To answer you previous question. You can flash any ROM that uses the stock kernel to run. Most of them are labeled stock based or based on stock firmware XYZ.
And as long as you have a recovery and made a backup beforehand, almost every ROM is safe to flash.

Can you set CWM to warn when a ROM tries to write boot image? Cause that would be ideal for people with locked bootloaders.
You can just check if there's a boot.img in the zip file I guess. Anyway, it'll simply fail and you have to restore an official rom, no big deal. There aren't many stock based roms anyway.
Does candyrom or the amg rom work with a locked bootloader?

wow.. but it says will only work on unlock bootloader.. mine is locked..
i just want to make sure that it will brick my phone..
this will be an expensive paper weight if that happens..
I've had a locked BL and that CWM recovery installed.
Then I unlocked my BL, flashed a kernel and the recovery and the backups where still there.

my bootloader is still locked.. i want to know if i can flash it even though it is still locked.. i still have no plans of unlocking my bootloader.. maybe i have to wait a little more before i can decide of unlocking it.. i am not worrying about losing my recovery, i am concern of bricking my phone..
Yes, you can flash it even with locked BL.

Hello!
I'm quite new to this, so bear with me.
I have an r800x CDMA Play - it's rooted (Superuser installed) and has CWM Recovery installed. I have a locked bootloader.
I'm looking to install a custom kernel and ROM. I have tried using Flashtool and fastboot alone to flash the kernel included in the AOKPlay ROM. However, I'm getting some errors - it says that I need to be rooted in order to flash a kernel but I am in fact rooted. Is it possible to install a custom kernel with a locked bootloader or is there a trick that I'm missing?
I'm using Windows 7 64-bit. All required drivers are installed. My device is in fastboot mode.
Any help would be appreciated. Thanks guys/gals.
Hi there! You must have an unlocked bootloader to flash a custom kernel. At least now you can do it for free though. Good luck!

Thanks for the reply.
How would I go about this? I've checked and apparently my phone does not allow unlocking (from service menu) - is there any hope?

Probably your only hope is via testpoint. It costs to unlock via this method however. Theres are a user called Alejandrissimo who can do this for you

No, you can unlock the bootloader for the R800x (Verizon) for free on Sony website.
Follow these guides:

Just make sure to replace and GSM version of file mentioned in the steps with the CDMA version of your choice.
I suggest trying the NXT (CDMA version) rom. CM9 roms doesn't have as good performance on this device for me.
Hey guys, as the post title says, I'm trying to install the xperia play z rom, and I'm hitting a lot of road blocks. First one is, I don't even know if my phone's bootloader is unlocked! I'm pretty sure it is, because I thought all r800a's came with an unlocked bootloader, and I also used the flashtool, unlock bootloader tool, and it said it was already unlocked.
So, naturally what I do, is I flash the firmware in the guide (located here - http://www.android-hilfe.de/root-cu...a-play/417392-rom-xperia-play-z-v1-1-0-a.html), and after that I want to root it so I can install a recovery. But when I try to root it, it always fails on part 1. So I tried to install cyanogenmod recovery without it. But after the apk is installed, i'm not able to install the actual recovery because it is not rooted.
My main problem with the guide is that it says to just boot into clockworkmod recovery, but I don't know how to. I turn on the phone and press the up button, but without installing the CWM/X-parts recovery, there's no way I can expect it to come up.
Any help please? I'm totally lost here. I know how to get roms that are based on gingerbread, but for some reason, Ics/Jellybean roms don't work at all, and I don't know if it is whether because my phones bootloader isn't unlocked (even though it says it is), or it's something else, like me missing a tutorial specifically for ics/jellybean roms.
Thanks in advance.

Well you have to flash an ICS kernel first and it will already have a cwm recovery in it. Then you can just boot to recovery and flash the rom

OHHHHHHHHH. Thank you so much. But how am I supposed to flash the boot.img for the modified doomkernel v3, which it says it includes in the guide? Am I supposed to extract it from the rom zip or something? Thanks again.

yes, boot.img is inside the zip. Unpack just that file and flash it with flashtool (in fastboot mode). But you must have unlocked bootloader to be able to flash any custom kernel

Sorry, another question. What happens is that when I try to flash an ics kernel, it goes into an infinite bootloop, but when I flash a gingerbread kernel, it works fine. Is this a sign of a locked bootloader? Cause I thought you wouldn't be able to install any kernels if it was locked.

If you flash ics kernel, you won't be able to boot your old gb rom. Ics kernel only boot into ics rom.
When you flash ics kernel, go to recovery and install ics rom.

Thank you so much. Worked like a charm.
For future readers -
a. The r800a indeed does come with bootloader unlocked
b. It is normal for the phone to bootloop, Just go into recovery like normal and install the rom .zip. (It's usually tapping back while starting the phone, but if that doesn't work, try up volume or down volume)

don't know if I should start a new topic or not since this is a few months old thread but I'm looking for a guide to install TWRP on Xperia ION with locked bootloader as well...
I know this is possible because I have a locked bootloader and TWRP on my Xperia ION right now...
I got the TWRP when I install CM10 for locked bootloaders by @MrGezz
I am on Slimbean rom now and I noticed that I retained TWRP even though I flashed a new rom... don't know if TWRP is baked on that rom or TWRP doesn't get erased even when flashing a new rom...
Anyway I want a guide to install TWRP because I want to try and compare the camera quality on an official stock rom and CM based rom, because I noticed that pictures taken from my camera started to get a little blurry and out of focus ever since I flashed a CM based rom.
And I think installing an official stock rom will remove TWRP on my phone...

You can install TWRP by Unlocking the Boot loader. But if you dont want to Unlock the Boot loader then you cannot install TWRP alone in a Locked Boot loader, But
There is another way. You can install Both CWM and TWRP together.
Try this CWM-TWRP Xperia ION Dual Recovery for locked/unlocked bootloaders
Follow the Instructions.

Installation Steps (Warranty can be restored whenever you wish)
-------------------------
Before starting your rom flashing journey it is always better to have Flashtool (latest -by androxyde) installed in your PC and your stock rom handy ; incase of any mishappenings.
Type *#*#7378423#*#* in your phone and see if your bootloader status is unlockable under service-->Configuration. Procede with below steps, only if your device is unlockable.
It is important that you follow the steps in order
1) First step for installing a custom rom over a mobile with stock rom is to backup the existing state of bootloader .Usually warranty will get void if any modification is done to bootloader. The below tool ensures that it takes the backup of existing state of bootloader when device is under warranty.
Goto
Backup TA for Sony Xperia (This tool helps you to have a )
http://forum.xda-developers.com/showthread.php?t=2292598.
Download the tool.This tool will backup your DRM Securtiy keys . Successful backup can only be taken after the existing stock rom is rooted (Use towelroot application if your device is not already rooted) .Root it first then follow the process given in above link .
Once this is over , u will have a backup of the existing state of bootloader/TA partition (If you later wish to move back to stock rom from custom rom use the same tool to restore the backup you have just created.This means you will get your Warranty back);
2) Goto this website , follow the steps and get your unlock code via e mail.
Use fastboot mode to unlock your bootloader (Make sure that you have already backuped your existing DRM keys-Step 1).Follow it fully to unlock your bootloader
http://unlockbootloader.sonymobile.com/unlock/step1
3)Download any custom rom zips with recovery, for your mobile from xda developers forum and have fun.Extract boot.img using winrar or winzip .
Flash boot.img via fastboot mode
fastboot flash boot boot.img
fastboot reboot
4)As the device reboots, when you see your LED glow press volume up or down. It will take you to CWM Recovery or TWRP recovery based on the rom that you have downloaded.
5)Just install the custom rom(*.zip ) from within the recovery.
What if that i already have the custom recovery?
So, just wipe data, dalvik, and cache, then flash the zip?
That's it?

Absolutely right. But before installing an custom rom in the first place i hope you have already backed up your DRM keys for warranty purpose(as mentioned in the guide) since if you unlock your bootloader without backing up your DRM keys, DRM keys might be lost forever .

Sure. Easiest way to do it is by using an app called, 'Titanium Backup Pro'.But you have to root your stock rom first for this application to run(Use towelroot if you are yet to root).Except for sony proprietary apps like walkman,Album,etc (will run only on stock rom as they use sony developed system libraries/API'S) other apps will get restored/run fine on a custom rom.

Sorry, did you type that in the phone and check the status? That's where it will tell you if its already unlocked or if its even unlockable at all.
Do not try to install a custom ROM on your phone if it is not unlocked! Your phone will not boot.

Thanks to @ foomanjackel for answering your questions.Regarding your 2nd question, 'Experience is the mother of invention'.Why don't you try and see what happens...just kidding.Couldn't resist it. Practically speaking of you install a custom rom with an custom kernel on a locked bootloader you will hard brick it.It will not boot and chances are that you might not be able to goto flashmode or fastbootmode anymoreto repair it.Reason this happens is that both your recovery and bootloader resides in the same partition in your mobile.If you try to install custom kernel on a locked bootloader in every probability, it not only corrupts your existing stocks kernel but also might corrupt your recovery leaving u helpless.
Theoretically, You should be able to install any custom-stock based rom on a locked bootloader (which runs exactly on ur stock kernel).In other words a custom rom which doesn't come up with a custom kernel but based on your existing stock kernel should be able to run on a locked bootloader.But my advice is you do not risk it.
