[Q] Flash Customised Firmware on Carrier Device - Xperia Z3 Q&A, Help & Troubleshooting

I'm still confused about this. Can we do what the title says? Been searching it for a while and I can't find any answers because probably no one asked this. Thanks

Yes you can. Without root you can flash FTF,s. With root & recovery you can flash sony stock based roms. With unlocked bootloader you can flash custom kernels

Ah thanks. Always thought there would be a conflict when flashing a generic firmware on a carrier phone.

Download this full stock firmware http://www.androidfilehost.com/?fid=23134718111254196 then use Odin to flash, once done take the OTA and it should be fine. BTW, once upgrade to 4.3 your bootloader will be locked permanently meaning you can't flash custom firmware (rom/kernel/recovery), the only thing you can do is root with saferoot. can be found here http://forum.xda-developers.com/showthread.php?t=2565758

If you still want to install custom firmware then DO NOT TAKE THE 4.3 OTA UPGRADE. If you decided to flash custom rom then after flash stock MF1, you need to unlock bootloader, root, flash recovery then flash custom rom (most custom rom already rooted so you probably don't need to root). Your phone status will be CUSTOM.

Haviing only used Odin when I initially rooted my phone a year ago, I need to ask some specifics on your instructions.
1. Do I boot the phone into Download mode when flashing?
2. Do I flash it by selecting the PDA box and selecting the file there?
3. This will make my phone basically "out of the box" and back to stock recovery, correct?
Thanks in advance.

The stock root rom is probably the most stable one. http://forum.xda-developers.com/showthread.php?t=2591895 just follow the instruction on this link.

[Q] Stock recovery image

Hey there,
does someone know, if there is the stock recovery image (for original firmware updates) available?
Thanks for your answers.
No there is not. Xperia devices do not have a stock recovery that you can access
But I can't update the stock firmware with custom recoveries.

Yes you can, use flashtool.net to flash a FTF
Or PCCompanion to update if you have not unlocked the bootloader.

No luck flashing ROMS with recovery

I'm trying to update to either official LP or AOSP lollipop, but trying to flash a zip with recovery just ends in errors with all the zips I've tried to flash with both clockwork and Phil Whi Touch, some zip files fail because of bad footer, some actually say "installed sucessfully" and then just reboot in to my old 4.4.4 setup.
Is this due to a locked bootloader?
I actually can flash ROMS using Sony Mobile Flasher but I've only found the 4.4.4 stock D6603_23.0.A.2.93_Generic GLOBAL.ftf file and not a LP version.
Any Ideas where to go from here?

wow,
OK, official lollipop does not need an unlocked bootloader but AOSP does.
Also, the official flashtool from Sony (Often called EMMA and downloaded from Sony) DEFINATELY needs an unlocked bootloader, it will not work without one.
Only the unofficial flashtool (From flashtool.net) will work to flash FTF files on both locked and unlocked bootloader.
Please provide the actual setup of your phone and show the outputs of recovery or flashtool once you try to flash
dont even try flashing any custom ROMs, youre going to end up bricking your device.
Wtf?. Please do not spread confusion here. Base your posts on facts.
Talk about scaring the users away from custom ROM's
I meant flashing custom roms (aosp: cm roms) on a locked bootloader lol.. My bad

sony z3 d6653 lolipop 23.4.A.0.546 root help

i unlocked the bootloader but theirs no way to root without downgrading to kk..
is theres a way fo rooting with this update can i have it
im new to sony and had a bricked problem yesterday
played a little bit with flash tool and managed to get out of it with the Unlocked bootloader..
And you were aware of such keywords like "camera DRM", "TA partition", "backup" before unlocking, right?
I've aswered you elsewhere too, but, the procedure is kinda universal (for Z phones that is): downgrade to KK, giefroot, XZDR, update to pre-rooted LL.
What's your issue with that? You do it once and you just flash the next version, keeping data, but wiping dalvik&cache.
i didnt keep the drm backup...
now i dont think i can restore it
it doesnt matter all i need to do it to root this and have the full power to my self
done and rooted and everything works fine..now i nned toknow if theres any pure android marshmellow available??

To root with an unlocked boot loader is the easiest thing, just flash an insecure kernel.
As for ROMS, head over to the development section and take a browse there.

Question Flashing ROM with Lock Bootloader

Hi I’m complete newbie , earlier I experience bootloop then I saw a blog that if I wipe data using stock recovery the problem will be solve but its not. So is there a chance that I can flash stock ROM with lock bootloader? Thanks in advance if someone will answer.
Yes it's called stock rom so you can flash with locked bootloader
But if is a custom rom you can't

How can I flash stock rom with lock bootloader sir ? what tool should I use ? TIA sir
Xiaomi flash tool
You can't flash anything with locked bootloader, not even stock rom.
if your bootloader is locked you can't do anything. After you setup a phone you must turn on usb debugging for future purposes like your problem right now.
