ROMs for Locked Bootloader

Hi XDA, I've got an Xperia Play that's rooted with a locked bootloader running ICS, I've used the method in this thread here: http://forum.xda-developers.com/showthread.php?t=1762372. So far all I've done is gotten it rooted and cwm installed. However, anytime I try to flash a different ROM over I get bootloop, hangs on the Sony logo. I've tried the installing the following ROMs:
http://forum.xda-developers.com/showthread.php?t=1877297
http://forum.xda-developers.com/showthread.php?t=1719746
If it makes any difference, I never attempted to install the ROM found here (http://forum.xda-developers.com/showthread.php?t=1790615) before trying any other ROMs, I just went straight into the ROMs listed above but no luck. So, my question is, what is the best MIUI or AOSP ROM for an Xperia Play with a locked bootloader, and how can I install it?

The roms you were trying to flash needs custom kernel which means you need to unlock bootloader, that's why you get bootloop. For AOSP and MIUI roms you need custom kernel which means you need to unlock bootloader. As for locked bootloader you can only use the locked bootloader ICS by vokal and Markphyton ICS.

I also found one MIUI ROM that said it could be installed on locked bootloader, don't remember where I found it but it said for locked bootloader put the nandroid backup in the recovery folder and install from there, which I did. It got past the Sony logo but then hung at a black screen. How can I unlock my bootloader? My phone status says my bootloader cannot be unlocked, though I figure there must be a way. Can anyone help me out please? Also, thanks for your reply.

I use to have that problem with stock based roms... Try do a full wipe and format system before you flash... The format system bit is important might just fix the boot loop it worked for me before when I installed markphytons rom...but when u format system you will lose cwm so your going to have to install it again

I still have yet to try markphytons ROM since I've wanted to use others, but I guess I have no other option and it's probably better than the ROM that the ROM I'm currently running.
I was under the impression that any ROM based on stocked ICS would work with the above method, is this not true? Where can I find ROMs based on stock ICS 4.0.4? I've searched but haven't had much luck...

Yea that's what I thought aswell but never tried any other roms...i always revert back to gb... It doesn't really make a difference which stock base Rom you flash they all have the same camera and gamepad problem I think

hi may i ask how you are running ics on your xperia play with locked bootloader and btw you only flash certain types of custom roms with locked bootloader as i have flashed nxtbean on xperia play with locked bootloader.

You cant run ics on your xperia play because ICS requires a ICS kernal. You are currently using a GB kernel (locked bootloader) and ICS cant use a GB kernel.

Of course you can run ICS for locked bootloader it's created by vokal1992 but it runs very slow but you can try his/her kickass Gin2JellyBean ROM

No you got it all wrong that rom is stock gb themed with ics. Theres nothing ics about it other than its skin.

ftf with root and cwm

hello every body
is there a .ftf file with root and cwm in it ?
i need it because every time i try a rom and have a no boot i need to flash a stock rom and root it and install cwm w then i can try again with another rom so is there a prerooted ftf file with cwm preinstalled ?? or is there a shorter way ??
sorry about my bad english (it is not my first language)

that was also my first question on xda, good old times...
No, it's not possible, ftf. files can only be made by Sony, so you've got to do always the same prodecure for flashing, rooting,....

thank you so much for your answer
so i think i will keep doing that long thing again and again

That's a really tedious procedure you're following. When I try a custom ROM and don't like it, all I do is:
1) If switching between an ICS ROM and a JB ROM and vice versa, reflash the kernel, then reflash the ROM.
2) If moving from one ICS ROM to another, or one JB ROM to another, just reflash the ROM.
3) If moving from ICS/JB to GB or vice versa, flash the stock ROM, flash the kernel, and then flash the custom ROM.
You don't need to keep on flashing the stock ROM, rooting it, installing CWM, then installing the custom ROM. Kernels, as far as I know, usually come with recovery installed. If you're in a bootloop, just follow the pertinent steps from the list outlined above.

if i say any thing wrong please correct it to me maybe you teach me some thing that is new to me

Go read the stickys, get some basic knowledge and learn something for yourself, then ask questions about what you don't fully understand, on an existing thread that you found while Googling.

bootloader locked or unlocked because it sounds like you have a locked bootloader, if it is unlocked then why dont you flash a kernel eg. kernel rush with CWM already on it ?

You don't need to install CWM again, even if you're in a boot loop. Once the phone reboots, keep pressing the "down" volume rocker, as you always do, and you'll enter into recovery. If you're moving to a different Android version (for example, ICS to JB), switch off your phone and flash the appropriate kernel. Then all you need to do is reflash your previous ROM or flash any other ROM that you want. However, that's only possible if you've download your previous and/or other ROMs onto your SD card, too. Do you do that before you flash?
I don't have any experience with locked bootloaders, but the user above IS of the opinion that you might be on one. If that's the reason you're having to go through so many steps to flash a ROM, why don't you try unlocking the bootloader of your phone? I'm more than certain your phone's not covered under warranty anymore, and unlocking the bootloader is definitely not going to fry your phone or anything of the sort.

[Q] Can i keep going on r800x Bootloader Unlock?

// It seem that i posted on the wrong section (had alot of tabs opened, sorry for my mistake, if any admin can move the post, will be AWZUM!)
Hello! im pretty new to unlocking bootloaders and stuff, and i wanted to know, i search here on XDA some tutorials and i found this one:
http://forum.xda-developers.com/showthread.php?t=1961298
How ever that tutorial covers 2.3.3, and im running 2.3.2 Stock Rom, also when going to sonymobile and following the steps to unlock the bootloader, itsays to dial *#*#7378423#*#* and check for rooting status, my device dosnt have that displayed ( as a side note, i rooted my deviced almost 2 years ago).
However, I Continued with the sony steps and when dialing *#06# , the cellphone does give me my MEID, i continued with the tutorial, and so far, i got in my mail, my key to unlock my bootloader.
My question is, can i proceed with unlocking my bootloader? i would like to install a custom kernel so i can overclock it, to play games a little more fluid, my current room its a Stock Rom, however ALL the bloatware apps are gone now, my phone just have about 12 apps, and its using 80 megas out of the 300 the xperia has. is this good or i can go better with a custom kernel and a smaller rom?also im from mexico, when doing this im gonna need to reactivate my cellphone or something on the company?
Cellphone: R800x (Custom Build.prop To Be Identified in the market as a R800i)
Status: Rooted
Rom: Stock Rom 2.3.2
Want To: Play games more fluid, try to overclock TO A SAFE SPEED. i dunno maybe 1.6? 1.5?
Thank you! C:

Update to 2.3.4 then it will show in service menu if you can unlock bootloader and if you want root then root through flashtool with 2.3.4

You can unlock your bootloader with flashtool. Doublecheck your unlock code you got from Sony. Make sure you have correct drivers installed. Verizon kept the root status in service menu hidden... But it will work.

Yes it will work but as lordomn said check and make sure all your drivers are good then do it and you should be fine

Thank you guys! so far, i got my Xperia Play atm very clean, i got it whitout ANY bloatware, i think almost same as the "Cola Rom", it only have like 10 apps, as a base, and it uses 70 megas from the 300 that it has, so my question would be, if there are any GREAT benefits from unlocking the bootloader, on the "Gaming" side of this, like what can i do after unlocking the bootloader that will pump a little my device on the gaming way?

Well you can flash a new kernel and over clock your device

Yeah, thats easy saying lo, but im particulari new to this.. theres alot of stuff involved, for example, im on 2.3.2 stock rom, i made a revocery image using CWM, and saved it somewhere safe, so here are the questions in order, ( if you can answer them in order would be great ):
1.- im on 2.3.2 stock rom, and i saw a kernel named 2.3.3 stock kernel with overclock, can i flash this with my stock rom and keep my stock rom, or i would need to flash first a 2.3.3 stock rom?
2.- when i want to test a new rom, do i need to flash the kernel first, or the rom?
3.- am i totaly safe with CWM and a nandroid backup?
4.- testing kernel is something safe? i mean can i go back?
5.- if something goes REALLY WRONG, can i flash the stock rom/kernel using flashtool?
6.- i found this http://forum.xda-developers.com/showthread.php?t=1605631 wich is the stock kernel 2.3.3 overclocked, but im on 2.3.2, can i flash it and stay on 2.3.2 or i need to flash the kernel and then the room, or first the rom and then the kernel?
7.- can i install CWM recovery on all the roms? i pretty much want to be safe, in case something goes wrong, or can i just use FLASHTOOL, to flash the stock firmware / kernel 2.3.2 and start over again?
8.- unlocking bootloader makes the xperia play able to use the flashtool, right? like, whitout unlocked bootloader, how does people flash roms for locked bootladers? using CWM recovery menu, the update .zip function? im pretty confussed right here, like, i unlocked my bootloader, so, i can use flashtool right, thats what unlocking the bootloader its for?

i think you can find the answer to alot of your questions here at FMA's thread it has a very good Q&A.... but anyhow ill answer them to the best of my ability.
1. im not sure as i never messed around with GB but i believe that 2.3.3 kernel will work on 2.3.2, but why would you want to stay on 2.3.2 when 2.3.3 has better performance?
2. Yes always flash the kernel first then the rom.
3. A Nandroid backup does not back-up the kernel as the partion its on CWM cant see... so if you get a faulty kernel flash or you flash a wrong kernel just use flashtool to get a working one.
4.yes you can always go back from flashing a kernel and yes its pretty much safe.
5. yes you can always flash with flashtool unless for whatever reason you damage the bootloader or the Trim Area then you have to seek for more advanced methods to recover the phone, dont worry tho if you dont accept an official update after unlocking the bootloader you will be fine.
6.i would be safe and upgrade to 2.3.3 using a .ftf so that you dont have any headaches.
7. yes you can flash CWM on all roms, however CWM is not part of the rom but the kernel and almost every costom kernel already has a recovery.
8.no everyone can use flashtool, unlocked or not except r800at models, no thats not what flashtool is for, flashtool is built to flash .ftf files to Sony Ericsson phones, it also has other functions like unlocking a bootloader and other things
if you have other questions just ask and i will do my best to answer them...

[Q] xperia s Change OS to 4.4 cyanogenmod

Dear forumers.
I usually do not ask stupid questions as that, but there I am very very confused
I just want to install some new OS to my XPERIA S (LT26i). Now I have all stock cellphone conditions with original 4.0.4 Android version.
My wish is to have phone fastest as it can be and all stable. I have read many many topics and guides there but I am still confused where to start. I need all flashtool, bootloader unlock, root, recovery, flash kernel, flash rom and do not know what to do first, second, third,... And I do not want to break up phone.
Can someone please kindly understand me and copy links of actual guides in right order? I need suggestions for 4.4 version OS-s too.
Best regards

Can someone just tell me where I must begin, and what to do next, and what is the last thing to do? (guess flash new rom)
I just need order of work from all stock phone. I understend the guides and I can find them, but do not know what is the right order.
Probably you don't know that it is not so easy to first doing that, but for noobs that forum is so hard to understand especially because of risk to damage your phone is something goes wrong.

Now you need to download a rom from the development section, then open the zip on your pc, extract the boot.img. Then copy the rom zip file on to your phone and flash the boot.img using fastboot or Flashtool. Then turn on your phone, and keep on pressing the volume up button to enter recovery. Then wipe everything except system and sdcard and then flash the rom.zip. Reboot your phone and it should be running kitkat

I have installed this on my xperia but it's not that it has to be. It's version 4.6 not 4.8 and it's not 4.4 kitkat bur 4.1.2 JB. OTA updater says: Error fetching update info: Invalid ROM (LeOpArDx) & device (lt26ii) combo!
And device is LT26i not ii. At 60 page of discussion the others have the same problem with version and updating.

download another rom from the xperia s development section that says specificly lt26i or xperia s or nozomi, version 4.4.2 or cm-11.0 and copy it onto ur devices internal memory -reboot into recovery (boot button+vol up hold until blue led) and flash ur new rom thats in ur internal memory. wipe dalvik+cahce and boot to system - u should be golden now :good:

cant install custom roms at all

Hi,
I never had this problem with other devices.
I have rooted my xperia z1c and installed custom recovery following the tutorial on xda. I was able to install xposed on kitkat and playing around with all sorts of rooted goodies ...
After that I tried no 3 times ! 3 different 5.0 custom roms. I followed the steps including wiping etc. Everytime I am ending up on a black screen with doing a reset through sonys software with the original unrooted rom.
I think I managed it one time to install a custom 4.4.4 rom without a problem. MAybe it has something to do with lollipop. Do I have to install a certain custom rom before installing a lollipop rom ? After flashing the rom I flashed the recovery fix btw. But I wasnt able to enter recovery mod ( black screen ) The phone seemed to work fine ( sony software deteced the phone instantly )
Any ideas?

to be honest I am not sure .. I used fastbood for installing the firmware , I think I didn´t. Do I need to unlock the bootloader to install custom roms cause I installed one without a problem ( 4.4.4 )
OK I check it. I didnt unlock my bootload so thanks for that .. but why was it possible to install a custom kitkat rom ?

Some custom roms use stock kernel. Stock kernel works with locked bootloader. If you want to run a CM based rom, you will need to unlock the bootloader, but make sure you make a backup of your TA partition first.
Unlocking the bootloader disables some of the Sony software and camera features.
These roms will work with a locked bootloader, but just flash the rom, don't flash anything - kernel/recovery after

Some custom roms use stock kernel. Stock kernel works with locked bootloader. If you want to run a CM based rom, you will need to unlock the bootloader, but make sure you make a backup of your TA partition first.
Unlocking the bootloader disables some of the Sony software and camera features.
These roms will work with a locked bootloader, but just flash the rom, don't flash anything - kernel/recovery after

Each device is different which is why you need to read instructions first.
