Xperia Z1 BL Unlock 4.4 - Xperia Z1 Q&A, Help & Troubleshooting

Hello xda community,
I recently upgraded from my .257 4.2.2 JellyBean to .757 4.4.2 KitKat in a series of flashing (.257 -> .290 -> .681 -> .757) .
After successfully upgrading to latest stock firmware thanks to NUT for his awesome tuts, i lost no personal data or settings neither i lost root.
But, after wandering around in the forum i said it'd be awesome to get a DoomKernel and start overclocking.
After reading certain stuff, i got confused and didn't really know if it was safe for me to do it.
So, i would kindly like to ask you..
-How can i unlock my Bootloader without losing personal settings and data? ( I read i should backup TA, can i do it via TWRP recovery?, and can i after unlocking BL, restore everything except TA to get my stuff back?)
-Also, after unlocking BL, can i flash DoomLord's kernel without again losing stuff?
-And, I read that it is possible to "get" the camera (or some apps from the camera) from Z2 to the Z1, is it safe, for me to do it, and if it's not hard to explain, how can i do it?
-Can I keep Bravia Engine, Clear Audio, Bionz etc after all this?
Any help is appreciated, thank you in advance guys.!
Everything I learn from you, pushes me to keep learning more stuff about the android world, and makes me want to share it with everyone! I've been rooting and installing custom stuff to last gen 2011-2012 and some 2013 devices for my friends for about a year or more and also, started to explain some of the stuff i learned to them, every last bit that you tell me, i remember it, and transfer it to others, thank you guys, you are my Sensei

You unlock the bootloader by following the official guide from the don't website, just Google it.
You will lose all ordinal days etc.
Backup your TA first using TA backup tool, just Google it.
After unlock you can flash doom kernel using Fastboot

Ok, thank you. I backed up with TA backup from pc and also full backup from TWRP. Unlocked my BL and restored everything from TWRP except kernel and TA. Rebooted and everything was just as before but with BL unlocked. Then i flashed doomkernel v11 and all is fine yet. Haven't had even one problem. Now i want to try installing superuser MOD, so i can try the z2 camera port which sounds awesome. But i read it only works for. 681 fw versions. Can i downgrade just by flashing the one that NUT had uploaded.? Or is it safe for my fw version to try.? Sorry to bother you again mate
:angel:

It should be fine on 757 firmware.
I am using it now on that FW

That's just great, which guide should i follow? this or this

The 2 links are the same thread.
As for that smart camera port, it is not working properly yet. I just meant the superuser mod is working fine.

Ooops, I'm sorry for that, fixed it.
As for the camera, I am thinking of downgrading to .681 and try this camera mod using this guide to apply superuser mod .
Is it worth to downgrade to .681 ?

[STOCK] LT30p Stock+Rooted 9.1.A.0.489 flashable in CWM

I know TiMiN8R made a Stock Rooted Deodexed rom for everyone but some people asked for just a Stock rom that wasn't deodexed so that's what I have made here. This is a stock firmware with only root added. Please note the kernel and CWM are not packed into this rom (though the reboot fix is) Please read the note at the bottom regarding bootloop issues.
Here you go: http://d-h.st/tAn
Installation for Unlocked Bootloader
* Make a backup - Always backup just in case you ****up (Data backed up through Sony's Backup & Restore app can be restored without issue)
* Flash any kernel you want to use that has built in recovery.
* Enter recovery
* Factory reset
* Flash rom.
Installation for Locked Bootloader
* Make a backup - Always backup just in case you ****up (Data backed up through Sony's Backup & Restore app can be restored without issue)
* Use flashtool to flash any generic ftf that can be rooted using Bin4ry's method. If you are already on a LT30 ICS/JB firmware that is rooted you can ignore this step.
* Root using Bin4ry's method.
* Install CWM for Xperia T Locked bootloaders
* Enter recovery, factory reset and flash the ROM.
* Flash the stock ftf (same version as the rom used ftf available in my signature) in Flashtool but uncheck Wipe Data, Wipe Cache, Wipe app Log. Also exclude everything except for Kernel. (This is needed to update the Kernel to the latest stock version otherwise you may get a bootloop.)
**Keep LTE**
If you have a LT30at or LT30a and would like LTE with the LT30p rom then once you have flashed the above go back into Flashtool and flash the latest LT30at or LT30a ftf. UNCHECK Wipe Data, Wipe Cache, Wipe app Log, and exclude everything EXCEPT for baseband. This should put LTE support back on the phone but keep the LT30p system.
*If you started on a rooted LT30at or LT30a firmware and flashed this rom straight from that you do not have to reflash the baseband as it is not overwritten by this rom.
You will need to reinstall CWM after flashing this rom if you want it. CWM is not baked into this rom.
**NOTE**
If going from ICS to JB you will get a bootloop after flashing and rebooting phone. Hold the power and Volume up button until the phone vibrates three times (simulated pulling of battery for non-removable batteries). You can then flash the JB kernel through flashtools to fix the bootloop.
You can also flash kernel from cwm.
http://d-h.st/wye
It's just a stock kernel with no cwm. It's especially for locked bootloader but unlocked bootloaders can use it as well.
Just use that link and you will find it

Hello Spectre51.
So, if I flash this ROM, it will use the Kernel I used to get into Recovery?
I'm coming from HTC devices, so Sony is new to me...
I would prefer to keep the stock kernel for now. In EMMA I do not see the option only to flash a kernel? I see the ICS stock .195 rom and then the JB Alpha build. Is that the .489 version?
I'm currently on the .489... Like the ROM but only need root on it.
Thx,
j
Download flashtool from the dev section. You can flash kernel s using that

There is some warnings at the end of the post about bootloop if you move from ICS. Have you read it. Perhaps you need to flash a JB kernel to solve it.

[Q] Unlocked Bootloader VS Locked Bootloader.

Hey guys,
as we all know, there has been a work around to gain root access and flash custom recovery to locked bootloader devices.
The only thing i heard was, that by doing that, NFC would not work anymore (but can be fixed) and your bootloader will have the status changed to locked forever (also believe there is a fix for this)
So i just want you guys' insights on what are the advantages of bootloader unlocking apart from the above,
Cheers guys~
I'd also love to know what's not possible with a locked bootloader.
My biggest question is whether I could still use droidwall since that's what keeps me from getting huge accidental data bills.
- The NFC works, I just tried it with a credit card as well as with one of the smart tags that Sony gave with the box.
- The Bravia Engine is disabled, however there will eventually be a workaround for this one as you can already get Bravia Engine version 1 running whenever you wish even with the unlocked bootloader, not the version 2 just yet. However, my take on this is quite positive as I appreciate realistic colours more to over saturated bright and overly contrasting colours, hence why I don't like AMOLEDs for instance.
- Other than that I have not noticed anything different in my device. Mind you it's much better since the unlock, as I have already flashed a custom ROM, I'm using Revolution but there are some really good other ones too, with all the bloatware gone, you can clear the bloatware you do not want without a custom ROM. I also have a custom kernel now, using Doom's kernel with no overclocks.
- Oh and I also have a mod for configurable switches in my notifications area so no reason to go in and out of Settings application or use Sony's laggy widgets.
- The ability to use AdFree and other root requiring applications is a great plus for me as well.
I think its very confusing. My bootloader is unlockable, and i would like a custom rom, but not sure what to do, and what i will break and not break. Its a bit of a jungle.

BE is DRM so umlocking means losing them forever, unless someone find how to relock BL again and restore BE
With unlocked BL you can flash any Rom and kernel.
With locked you can flash only stock based Rom and can't flash CM roms

Twrp is just a recovery, like CWM recovery
So still you can only flash stock based Rom
To flash CM Rom or any Rom that is based on CM or even AOKP roms, you need unlocked BL.
These Roms use a different kernel than stock kernel.
Unlocked BL is needed to flash these custom kernels in kernel partition
Go to XS dev section, you will see alot of Roms that need unlocked BL

My favourite part with an unlocked bootloader is that with proper knowledge you can handle memory handling, CPU scheduling, under or over voltages on your CPU/GPU, etc.
So really the unseen side of things, my Xperia Z goes 2.5 days with one full charge with the modded kernel I have, using AOSP with nothing unused installed.
I wouldn't have been able to achieve that with a locked bootloader.
And I did not really like how overly saturated blues became with Bravia Engine anyway, so nothing lost on that side really.
I unlocked after the first 24hours of stock use.

Yes, you can use stock (XPERIA T) FTF's - just skip the baseband portion before you being flashing so you keep your AT&T baseband.
Then root with whatever method is needed
Then install CWM recovery
Then yes - you can flash stock-based (XPERIA T!) roms. You can usually tell the rom is stock/Locked Bootloader/LBL-friendly in the title of the thread, or in the first few posts of the thread. Also, I don't know how important this is - but also look to see what stock kernel the rom is based on (LT30p 141? 145? 489?). Stock kernel zips can be flashed via CWM recovery (I know that my Bell LT30a works fine with LT30p kernels, but I wonder if the AT&T LT30at will also be fine with it?). My favourite ROMS have been XperimenT and T-Hybrid so far... Good luck
And always keep your stock FTF handy! Because if any flashing you do doesn't work, you can always quickly fall back on a fresh whole FTF flash that is appropriate for your phone. Then the fun starts all over
Kernel
I did flash the kernel 145 from the T idk what really went wrong but my phone stuck on the sony logo
also i use XperimenT rom and flash it using CWM it install in about 7 secs which doesnt seems right . any suggestions ?

after trying diffrent method and days of trouble shooting with my friend
LaZiODROID there is a solution, using cwm(v9) would not format your system and data files thats the reason why the rom hangs at the sony logo because no system files were installed if u check the log, using cwm(v8) for the T,TL is the most stable and will install the rom and kernel with ease. Remeber to always wipe/factory reset then format system and in advance settings wipe dalvik before u install any rom.

[STOCK][UBL] Android 4.3 Long Winded Rooting Guide

Hello guys, i have been playing around with the new offical 4.3 rom, I have found a little way for now to get rooted, take a look below...
***Disclaimer, I am not responsible if you blow up your phone, loose data, or do anything silly, I am merely trying to help, and point people in the right direction***​
Okay it's a long winded approach to get rooted, but i guess it will have to do for the time being... Until a new updated rooting tool is available.
Here we go then , you will need these things:
SuperSU Install zip
Doomkernel v08 kernel.elf file
Stock Sony 4.3 kernel, attached to this post.
UBL (Unlocked Boot Loader!)
A brain and common sense.
Lets go then, first install the stock android 4.3 FTF....
Once this is done disconnect your phone, put it into fastboot mode and install the Doomkernel. Now upon boot, go into recovery, and install the SuperSU zip normally.
Once this is done, power off your phone (Holding down the power and volume up)
Go into Fastboot mode again, and install the provided stock Sony 4.3 Kernel.
Unplug your phone, boot it, and there you go, rooted stock android 4.3.
If you have any questions ask, no question is too stupid, or PM me and i'll help you best I can.
Reserved for more information, FaQ ETC...
I guess its only for unlocked bootloaders, because after flashing custom kernel on locked BL xperia, it won't boot.

No this method is only for Unlocked bootloader.
V7 should work just fine, all we are after is the recovery to flash the SuperSU
Thanks a lot it's working
Never did before on sony and the biggest problem for me was entering in recovery, so just in case, to enter recovery, when LED is pink press {vol up for 2012 models} or {vol down for 2011 models}
(used 1268-6904 Generic Nordic)

I can have root with that? With locked bootloader?
HELP ME!
HELP ME!
I tried this method on my Xperia V. I flashed the kernel then accidentally booted into android. Soft bricked. So I flashed back Sony kernel.
Working now but now there is something wrong with the screen.
I'm not sure what's wrong but it looks like the gamma is too high. I'll post a picture.

[Q] Is it worth unlocking bootloader?

I have C6903 .757 rooted using [NUT] way, is it worth to unlock my bootloader now, what I can get and what I will lost? beside thatis there any custom rom that better than stock rom for now?
IMHO not worth it. Keep your X-Reality and BIONZ and other Sony exclusive software. I hate buggy camera and sleep-of-death issues, so I keep my Z1 on 4.3
But keep an eye on this ROM: http://forum.xda-developers.com/showthread.php?t=2714333

Sony stock ROM is the best
Except you don't want Sony UI,then you can unlock bootloader & flash CM11
You will lost DRM keys if you didn't backup,X-Reality won't work for Pictures & Movies
No feature will disappear from unlocking the bootloader. Stated by Sony themselves. Before 4.3 stuff did happen though.

If I could I would. I want Miui and CM12.

WE HOPE TO FIND WAY TO KEEP X.R WITH UB THE STOCK ROM NOT GOOD if anyone try aosp rom he's know or cm rom
-more customize more features more speed and more more more
but the camera app sucks
Avoid warranty
I think the worst cenario it's lose totally the warranty. I don't know if you relock bootloader the warranty back's together, but I don't think so:good:

When you relock it will be back to stock. So I guess you will not lose anything.

Pre 4.3 this was the fact. Camera ceased to work and other functions aswell. The DRM keys did matter there. The tech guy from Sony also confirmed this.
Kitkat version though this is all fixed. And like he said to quote him "Nothing will change software wise with just unlocking a bootloader under Kitkat, aslong as you dont flash custom roms ofc."
So to translate this: The DRM keys aint used in KitKat. And it is very easy to confirm this yourself. Google the functions that people say will stop to work with no DRM keys. None of thoose has stopped to work with unlocked bootloader for me on KitKat 4.4.2.
And for the camera, the camera working worse under KitKat as you also can google and find information about. Unlocked as Locked doesent matter, and this is possibly one of the reasons why ppl still think, Bionz, X-Reality and other functions stop to work with unlocked bootloader.
But is it worth it? Well that is up for anyone to decide for themselves. Since KitKat, the phone aint working so well anyway imo. So if it would die on me i wouldnt care. I will probably not buy Sony in future though, they used to be good but something has happened.
For real?

Are you sure about that? Cus I do not unlock my bootloader yet because R$1500,00 is much money for avoid warranty in first days of use! LOL!
If it's true, i'll unlock and relock later..

Positive.
Unlocking bootloader in 1 2 3...:fingers-crossed::fingers-crossed::fingers-crossed::laugh::laugh::laugh:
Now I'm curious:
How, where or why are custom ROMS faster than stock ROMS?
I really can't complain about the speed of my stock. I haven't unlocked my bl yet (no need for) but I doubt you'd see much difference in speed between stock und cfw.
It was different on my sxs. Latest aosp or fxp was definitely more fluid but the z1 is a powerhouse.

Nobody said they are more faster, they are tweeked but at the moment on Z1 they are in development so before see a wonderfull stable Custom Roms you have to wait.
BTW, many Custom Roms are based on Stock Kernel so you will never see any difference. The heart of the tweekness and fastness on Android it's the Kernel, it's the main reason.

You can install CyanogenMod if your bootloader is unlocked. If you do that you will lose all your data and warranty but I think its worth it. You will have more control over your phone (privacy settings etc) and much more.
If you want to do that you should do a nandroid backup before and most important a TA backup. TA backup is for relock the bootloader if necessary (so you have warranty again). You can find TA backup tool in this forum, just search for it.

You need to downgrade to other version (for example .257), then root this and do update to the new version. Then you will have 754 with root.

Unlocking the BL is for rom development mainly. You will be able to load CM11, but so what. The stock rom is excellent for most people and its nowdays to tweak the interface in so many ways its silly.
