U don't need to unlock ur bootloader mine is for example able to be unlock I choice not to because u gonna lose bravia engine 2 meaning pictures video etc won't look as good anymore. Anyway to answer ur other question u need a ftf 4.2.2 rom from a C6603 I would go European because u won't find an USA C6603 ftf. Don't worry they all have English. So ftf rom, flashing tool, dual recovery, doomlord easy root, that is the 4 tools u need. Well actually only 2 of u don't wanna root or have a recovery.

Just to add; you cannot unlock the bootloader on a C6606, so custom kernels etc are not an option for you. So, you will have to stick to stock based roms.

So, I can flash a ftf of 4.2.2 stock rom from C6603 on my C6606 by using flash tool? There are too many t-mobile apps installed in the system that I just never used them.

Yes u can and u will be basically bloatware free and u should be still able to delete a lot of the apps that still come on that C6603 roms. The only thing u gonna lose is t mobiles wifi calling option but other then that u have a much cleaner rom and with 4.2.2 there are even small enhancements. Oh and u need to reapply all the apn settings and lte settings again on ur phone after flashing a C6603 ftf

root xperia z
i tried to root my tmobile xperia z c6606 build # 10.1.1.B.0.166 and it just wont root. can anyone please help me. thanks

I got my phone last weekend and have been reading through the forums to get answers for questions as the come up. On the T-Mobile support forums I thought I read that they didn't release the 4.2 update because of issues that were present in the update. Someone there said they are going to release 4.3 and skip the 4.2 all together. Would European versions of stock software carry the same bugs for 4.2? I don't even know what the problems/bugs are.
I'm mainly interested in rooting the phone so I can get titanium back up running, greenify, and disable the bloatware. I'm rather fine with the stock Sony firmware.

[Q] Flashable Roms for T-Mobile Xperia Z

So far I haven't seen a whole lot on this just that CM doesn't work right now. Does that mean roms like Paranoid Android and PAC Man won't work either??
Which type of roms will work?
Can anyone list a few of the best ones? Mine's coming through UPS on Wednesday and I wanna be prepared to do everything right away. Thanks!

I assume you mean the C6606 (the T-Mobile US Z).
If so, you can only flash stock based roms.
The bootloader cannot be unlocked on the C6606. Locked bootloader means no custom kernels, which in turn means no roms like PA, CM, PAC etc will work.
So, to answer your question, any rom that says it's for locked bootloader should work.

Okay I've since rooted my phone and installed dual recovery. do I only have to flash that 15mb ftf file now? That's where I'm stuck at. The instructions in that forum didn't exactly work for me. Can you tell me everything you did please? Hopefully you can get back to me in the next ten hours thanks for your help

I'm opening flashtools. I click flash at the top, click flashmode, then I click that newest ftp and click flash. The window that says wait for flashtool pops up.I power off my phone..hold down the volume up button and enter the usb cable. The light turns blue and I believe that's fastboot mode but nothing happens. That window just stays open on my computer. It's ftf C6603_10.3.1A.0.244_GenericCE-stripped.ftf

Volume up is fastboot. You don't want to be in fastboot mode.
You need to hold volume down and plug the USB cable in to enter flashmode to use flashtool.

I have the T-Mobile Sony Xperia Z. First I rooted with doomlords method. Then I installed dual recovery. I made a backup of my phone and installed the newest ftf file using flashtools. Then right after I flashed the rom that was posted above. It's working great so far and you keep lte and wifi. Hope that helps. It really is the best rom available to us at the moment because of the locked bootloader.

i have been researching this. it doesnt seem like there is going to be anyone who can unlock the bootloader. but there might be another way around it kind of like "mini loader" basically we will be able to flash aosp roms and custom kernals just no unlocked bootloader. pretty much jump thru hoops to do anything with c6606 t-mobile has Royally F'ed us... i really want someone to unlock that bootloader n RUB IT IN THEIR FACE! i dont know why they bothered with this... but theres got to be a way around this.... keep on hoping and lets see what happens i guess...

My xperia z should be arriving in the mail soon so I have a few questions. Just to confirm can the dual recovery foound here: http://forum.xda-developers.com/showthread.php?t=2261606 be installed on the c6606? Also are there any custom roms based on the t-mobile firmware because I would like to keep wifi calling. Thanks.

He meant Wifi Calling, which is only available on T-Mobile firmware. He just put a period in the wrong place.

Bump...any new Roms where we don't lose wi-fi calling?

None that Ive seen. Only ROMs for locked BL that are coming out are based on firmware made for the international market (4.2.2), none on T-Mobile (4.1.1).
The locked BL is really disappointing. Really limits the possibilities. I bought the Z on impulse and didnt research the Development situation on the Tmobile version before i bought, now im regretting it. I love the hardware and design, but will likely be trading it in by Christmas because of the lack of options for custom ROMs. Samsungs may be ugly as hell but you can hack the hell out of them. If HTC makes a phablet with the design of the One, Ill probably make the switch.
Back on topic, which LB ROM is most recommended and bug free? Any way to fix the poor wifi signal? Its chewing my battery like nobody's business.

Really disappointed with no custom Roms too might trade for another phone but not going to samsuck. Still have faith in what the devs here can do though.

Odd way to unlock bell xperia z or t-mobile xperia z bootloader?

Hey guys,
I own both the bell version of the xperia z, and the T-Mobile version. I ONLY want to use them as glorified tablets. Basically like the Ipod touch version of the iPhone, I want to use them unactivated. For me, its all about customibility and I really want to unlock the bootloader. I know neither of these can be unlocked, but in theory, if i wrote the software of the global unlockable versions (c6602/c6603) which DO allow for unlocked bootloader, would I be able to do it? I know signal would be screwy with the radios, but i dont care since thats irrelevant to me. Any help would be great, thanks guys.

Short answer: Never going to happen.

So its impossible to write c6602/3 software to it? Longer answer would be nice : P

Sorry, you can't unlock the bootloader if a device says: "bootloader unlock allowed: no" which is if you have a branded device. If you try it, you'd better throw it away.

If u can root everything is possible. As long as there's someone who provide geeky solutions
And under your situation u don't need flash different rom as there's a way to install recovery without unlocked bootloader in rooted phone.

hey, thanks a ton for the responses guys! So, is there ANY possible way I can get cyanogenmod installed on either my c6616 or c6606? (Bell and t-mobile)w

I don't have your phones so I cannot guaranty but you can try my method.
I got a c6603 from vodafone, and use ota to update to 4.3.
Since the 4.3 cannot root and I dont want unlock bl. so I use these steps
1. downgrade phone by flashtool to a version which can be rooted.
2. root
3. install recovery in locked BL:
http://forum.xda-developers.com/xpe...cked-bootloader-cwm-recovery-6-0-2-8-t2187363
4. Choose whatever rom you like and flash it.
DONE!

You cannot use custom kernels on a locked bootloader, so you cannot run CM, PA, AOSP etc.
Stock based roms only. There's no way around it.
Sent from my C6603 using Tapatalk

Awesome tips guys! Got recovery working and its all good- just ONE last thing:
are there any vanilla style roms out there like cyanogen that are stock based? I just want my pure android with some nice customizable features, no kernel updates or anything. Can you suggest any?

Hoping you guys will help me on this matter :fingers-crossed:

Thank you #gregbradley
Actually, I wanted to Flash Custom ROM on my Device but many article says: "Unlocking the boot loader allows you to put custom ROMs on your device" It is true ?
Regards,
Clasher_RS

It depends if the custom rom needs a custom kernel, some do, some don't
But in general, if you find the custom rom in the development section you only need root and not an unlocked bootloader, but if it is in the original development section then you need an unlocked bootloader as that rom requires a custom kernel.

[Q] TMOBILE 6606 upgrade possible?

Does anyone know if TMobile brand Sony Xperia Z able to flash the other ROMs. I know it's BL and will lose TMO Wifi call function. But TMO stop at 4.3, and I cant see any hope for 4.4, 5.0. Is possible to flash other ROMs? Thank you.

Yes, you can.

WIFI calling function will not work ofcourse but if you are not satisfied you can flash stock firmware anyday using XPERIA FLASH TOOL. You need to unlock the bootloader using official Sony Method. If you can unlock the BL which I was able to.
Then you can download and install Cyanogenmod 13,12,11,10. (C6603) - Yes, it has issues, so I switched to.
SlimKat 4.4.4 - YUGA (C6606) - NO BUGS AT ALL.
Also do remember to flash SGAPPS from their repository no the opengapp.org gapps.
Big difference I found is that Stock OS on new flash takes around 500-700MBs of RAM where SlimKAT takes only 350MB w/o GAPPS and 500MBs GAPPS.
Good luck! I will show you screenshots

The official tutorial is over here: https://www.youtube.com/watch?v=jWPYicb8_-Q

I guess that means there's still no way if your C6606 says "Bootloader unlock allowed: NO".
