[Q] Custom Rom Flashing - Xperia Z1 Q&A, Help & Troubleshooting

Well hello, I'm kinda new to Xperia Modding and I'm trying to install a custom rom on my phone.. I just have some questions first:
1. Is there any custom rom that allows me to send apps and else to my external SD Card?
2. My phone can't unlock the bootloader since I checked that and it says it can't.. can I still install roms that way?
3. I'm trying or I want to install the Evo9 Custom Rom .. and my phone specs are the following:
Model: C6943
Android Version 4.4.4
Baseband Version 8974-AAAAANAZQ-10270054-51
Core Version: 3.4.0-perf-g0109737
Compilation Number: 14.4.A.0.108
What do I exactly have to do in order to install that custom ROM on my phone? since the tutorial for lockedbootloader phones is really confusing..
/!\ for locked bootload
If you come from 761 or before
- Flash the ROM by recovery
- Flash the Gapps
- Power off
- Flash by flashtool the good kernel (C6902/03/06/43) for your device 108ftf strippedkernel by Nut...
Reboot and enjoy

What's 761 exactly? that number doens't say anything to me actually ._.
and the "flash by flashtool the good kernel" isnt' making sense to me since I assume I'm ignorant.. please could someone explain those things to me?
Thanks in advance.

1. Yes
2. Yes but only stock based roms
3. You have to get phone rooted and custom recovery installed

No, once you have the recovery you flash the custom rom from there

I'm on .108.. do I need to reflash the kernel? or it stays untouched?
Does this work with any operator?

root, then flash baseband ending in 015, then install xrecovery, and then use xrecovery to install custom rom.
This Baseband is an official one, I think it comes with the original ".6" and the ".C.0.0" build, so you have the choice beetwenn flashing it via Flashtool or updating via PCC.
move.........
hmmm...

I tested it and working with xperia arc 2.3.4 (.42) fw!
I suggest you changed the title something like "cmw recovery on locked bl and more". I think many want recovery with but hesitant to unlock bootloader. Thanks for posting.
works perfect on rooted stock arc locked bootloader
sounds wonderful. I shall try on mine too
Can I install ROM now from the dev section in the forum?
can confirm that this does not work on the Xperia acro IS11S
so does this allow a recovery menu for devices with locked bootloaders, does that mean we can flash custom firmware on these devices. if not what are the benefits of locked bootloaders having a recovery menu

Try it! lol
If we install CWM using this method, is there a way to remove it if we need to claim the phone on warranty or anything?
Also can more people confirm this definitely works with stock fw, locked bootloader

Are you sure that'll work? You still have a locked bootloader so custom ROMs probably still won't work. I think it more for backing up stock ROMs and installing mods etc.
ah ok i guessss your right....can we flash themes?
I have no idea. I'd like to know actually. Would make it a lot easier to test things that may cause a boot loop and be able to just flash back to stock without a full reset.

You can't upload the CM7 because CM7 need another Kernel. CM7 don't working with the stock kernel! If you make change kernel you need the unlocked bootloader phone.
I think that this works:

Yes, but this is just a rom in ZIP file, just flash with CWM over the original stock rom. Test it if you have time!?
How about adding a (second) post / sticky in this Topic, with Roms, Tweaks etc. that work by CWM flashing... (locked bootloaders)

If you want to flash an aosp rom, then you would have to unlock your bootloader and flash the rom through recovery

Yes you can install custom rom but need to be based on Sony firmware
For AOSP ROM you need to unlock the bootloader & flash it through recovery
Flashtool is to use for flashing stock ftf

well u can still find another launcher for your z1 and use Xposed framework to modify a lot of things since u have rooted
custom rom like CM is a (slightly) more experimental stuff and are usually used by people with more experience in android.
not recommended for u at the moment bro (well u cant unlock anyway)

Rooted with towelroot.What next?

Dear all,
I have rooted my device which is running 4.3 (c5502) (build number: . 101) with towelroot. Now i need to install any custom ROM. I came to know that it requires to install recovery first before flash any ROM. I stuck there..Can you please guide me. I didn't unlock my bootloader yet but I had my TA backup with me.Thanks in advance guys.
whatever u need to know is already there. just search for it. if u expect to be spoonfed then you really shouldn't mess with your phone
The thing is, do we really need to unlock boot loader to flash custom roms, or can it be closed just with root and recovery?
No one tryed it till now I think.
Greetings.

Yes for flashing custom Roms the bootloader must be unlocked and a recovery must be installed however if you want to flash a stock based Rom unlocked boot loader is not needed. Just Root and Recovery needed for flashing the stock based Roms. Correct me if i am wrong.

No there is no hardbrick . If you are not on the right bootloader and modem the rom may not boot , so you just flash the right ones.
If you want to came back to LP flash lollipop last booloader and modem and you are ready to go.
Basically , bootloader allows you to boot the rom , modem is everything related to signal , wifi...etc if you are in the wrong one you will not have signal or some things working

Yes, you can. First backup your android 6.0.1 from your recovery, in case something go wrong, you can go back.
Won't flashing/ downgrading the bootloader brick the phone ? How do you flash the LP bootloader and modem?Please can you give a step by step guide and where the correct files can be found? Thanks
