Possibilityes for Pure Android 4.4 for LB - Xperia Z1 Q&A, Help & Troubleshooting

Hello all. I am wonder if i port CM11 to our XZ1 with Stock Sony Kernal. Would it still work or not boot up at all. I am trying to see if i can help somepeople with LB. As i can not unlock mine
Thanks
-JPH ~Connor~

You can try to flash CM11 excluding Kernel, leave Stock kernel intact, or flash CM11 excluding kernel and then flash Stock kernel from flashtool, and see if it boot up, but I doubt.
If it not, In this scenario, as you didn't flash custom kernel, just reflash stock Rom and you are fine again and you phone should boot.

It will not work

Its based on the kernel, which you cannot flash with a locked bootloader

I know that. But there must be something stopping it from booting

Yes, the bootloader will not boot an unsigned kernel.

Are C6603 roms and firmware compatible with the US C6606? Will I need to unlock my boot loader to do any off this stuff or no?

Yes C6603 work fine. And no u do not have to unlock ur bootloader. U can still flash stock based roms root and install recovery on to the xperia z even with locked bootloader. U gonna lose bravia engine 2 if u unlock ur bootloader.

If you cross flash your phone (e.g. flashing C6603 firmware to a C6606 phone), it is no longer possible to update or restore your firmware through any of the official ways (Sony PC Companion / Sony Update Service / Sony Bridge for Mac / OTA), because your TAC (Type Approval Code = first 8 digits of IMEI) doesn't match anymore. C6603 TAC is 35576205 and C6606 TAC is 35676805.

What? U can flash ftf C6603 to a C6606 that is no problem. U need flashtool then u also can root it doomlord easy root and u can even install a dual recovery even with locked bootloader. U just can't flash some costum roms CM based ones with an looked bootloader. Other then that it really doesn't matter. Just make sure the rom says looked bootloader when flashing.

Yes. Agreed but what if OP thinks differently? i think we shd inform OP about TAC consequences if flashing fff of another model number of same Xperia Z. Just as apollo said. Let OP decide whether wanna do that or not. But this abit warning needed to be given in formal. Cheers.

Yeah well yeah he shouldn't flash a C6602 rom because then he loses the option to select lte.
Sent from my C6603 using Tapatalk 4 Beta
The first thing to say would have been that the bootloader on a C6606 cannot be unlocked anyway.
You should also have advised the OP to exclude the baseband during flashing of a C6603 ftf to a C6606 as flashing the baseband would apparently cause loss of LTE.
Edit : Apparently, it is safe to flash other basebands. Just going off what other people that actually have the phone were saying initially. I stand corrected on that one.
Or just link to one of the threads where this has already been discussed, like this one - http://forum.xda-developers.com/showthread.php?t=2372664 instead of going over the same ground again.

I see people succeed in reverting back to stock through beta 4 but i can't. I have no idea why too but guess I have to stick with beta 4/5 for a while.

Are you serious?? Flashing stock 4.3 using odin
Sent from my GT-I9305 using Tapatalk
What else do you flash with ???
Let's say that 4.3 update has knox bootloader and not everyone wants to void their warranty by updating theirs.
Hmm.. It is also possible to flash only kernel by MobileOdin, I am curious whether it will boot then...

In fact some guys reported on this. And I am not able to flash stock kernel from mine ported boeffla either.
However I don't need stock kernel for anything, therefore it isn't the most important issue

Hmm agree. But it seems 4.3 is draining more battery than 4.1.2 IMO.

[SOLVED] Struggling to get into recovery

So my bootloader is unlocked and my device rooted, trouble is every recovery I flash doesn't want to boot. I'm on the three branded 257 firmware, is there anything I can use or do I need to upgrade to a newer one?

Help flashing with flashtool.

I'm trying to downgrade my xperia z1 c6906 so I can root it. It's locked bootloader on 4.3. When I try to flash I get the error error. Invalid literal/length code any suggestions

Using latest flashtool? Read up on downgrading from 4.3. Some users have had major problems.

I'm not sure to understand but you can root your phone in 4.4.2 too
Also be sure to have the latest Flashtool version.
BTW i'm not agree with augie7107, there is no major problem to downgrade by flashing a FTF file with flashtool.
There is no root method for 4.4.2 without unlocking the boot

Yes but you can flashing a pre rooted rom, that doesn't need to unlock your BL, i'm using the 4.4.2 NUT ROM with locked BL.

I used both methods, first tried with philz and not start to see that I used fastboot
After you flashed the kernel using fastboot, did you then boot into the included recovery and flash the entire zip? That's the usual procedure for flashing a custom kernel, as there are usually files needed for compatibility in the zip.
I just checked the kernel thread and it looks like v25 has been released, so perhaps try that also. ?
