Hello.
I searched some but i could not find the answers so hopefully i can get them in this post.
Well what i was wondering about is: I have unlocked my bootloader the official way. Let´s say i wanna relock it again, flashing a stock kernel.sin and using flashtool to relock it.
What method is then used to Unlock it again if you would wanna do that ? And i dont want guesses here i want solid facts of what works and not.
/Jonas740
I just use FlashTool to unlock and relock after officially unlocking it the Sony way. I haven't experienced anything odd or harmful doing it this way. Seems to be nice and safe. Currently my Z1 is rooted, stock kernel, dual recovery installed and bootloader locked and it's working great!
dual `?

Dual installer recovery ?
Im kinda newb but wont root go away if you apply stock kernel ? what kernel are you using. had a hard time finding stock ones. Unless you mean to just extract from a ftf file.

On Locked Bootloader you can use Custom Roms with Stock Kernels as it is the only one kernel what you can use on Locked Bootlader.

Ye but do you extract stock kernels from the ftf´s available or will it just wipe the kernel if you flash a ftf from the big ftf list ?
Before flashing JUST the kernel from the Global Generic FTF posted here I flashed (in recovery from ADV Stock Kernel) NUT's dual recovery for Z1 from here: http://nut.xperia-files.com/
Then after stock kernel flashed I relocked bootloader in FlashTool and still have access to recovery if I need it (say I lose root) and can always reflash Update SuperSU from recovery and booyah!! Root restored though I never lost root but if I do I can get it back super easy!!

I don't know what exactly you mean. If you want to keep your kernel you can flash any Stock FTF and exclude Kernel in Flashtool, that will wipe the system but the kernel will remain the one you have, it's called Dirty Installation.
If you have Custom Rom with Custom Kernel and you want, for example, relock your bootloader then with Flashtool flash the Stock Kernel only, how? Just use any Stock FTF, put it in Flashtool folder, select the FTF and exclude everything and leave just kernel clicked, it will flash just the Stock Kernel from the whole Stock FTF.
Done.

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.

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

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)

I can't install CMW or anything, so isn't flashing things impossible?

you can install cmw on a rooted phone running 7.0.A.1.303 firmware, and you can flash that firmware with flashtool. Read the all in one thread from my signature.
Also, I must ask, why did you root if you didnt know what to do with it? You have just killed your warrenty for no reason..oh well.
What you can do with rooted and locked bootloader
Remove bloatware/debrand phone
Gain access to system partition
install cmw (In 303 Firmware)
Flash stock based roms like mine (Find in my signature) Its 195 based so you will be rooted and still have cmw and be on 7.0.A.3.195

Wrong forum bro, this is for development, not for Q&A.
Anyway, u can check ur bootloader status by type *#*#7378423#*#* in dialer (*#*#service#*#*)
Then tick service info
Then tick configuration
U will see bootloader status there
For other questions, use search function or use Q&A forum :thumbup:

You have to unlock the bootloader before you can install non-stock kernels. Search in the forum on how to unlock the bootloader. As the person above said, go to the service menu and check if it say Bootlocker unlock allowed = Yes or No. If it says No, then you are stuck and can only install stock based roms. If it says Yes, then you have to manually unlock the bootloader once using step by step guides available on xda or sony.
1. hi all i wanted to ask for ur guidance/procedure on how to recover from bootloop if recoveries aren't functional after u've flashed a custom ROM.
2. what will happen if we flash kernel to LOCKED BL?
plz exclude flashing the stock FTF file, i need other options aside from reflashing.. i knew it already.

1. You are sure you did it this way as said under point 2?
2. It depends.
As far as I know - most base of all base rules is to stick to proper kernel.
Locked BL requires kernel for locked bootloaders.
All parts of ROM has to be consistent together. system, boot, kernel ...
Either for locked or for unlocked BL. Mixing stock and custom ROM parts is very unhealthy.
I think you need to know if the device enters in flashmode, next would be flash a new stock rom ftf with flashtool.
If the steps are OK you should have your device fixed, and have the bad xperience mixing lb ub Kerns could be....
Hope 2 have helpd you

as i told u all that flashing the stock ftf is excluded coz i already knew it..my phone is ok i just wanted to have a work around or any ader option that pass the bootloop w/o flashing te whole fw.
My phone still unroot and locked Bootloader and Im made mistake upgrade to latest official stock ROM lollipop 5.1.1 bec im having overheat issues, battery draining and weird popup. then im about want to downgrade to kitkat and flash ftf firmware with root.
1) Do i have to Backup TA before i use flashtool? i think if i do flashtool, i will lose DRM keys like sony features? (for locked bootloader)
2) What meaning by 'pre-root' firmware? (*sorry about this. it look new word to me*)
3) without root phone and unlocked BL, is it possible to use PRFCreator? (link: http://forum.xda-developers.com/xperia-z1/development/c6943-368-official-lollipop-5-1-1-t3218004)
I made decide not to unlocked bootloader bec i know its risk to lose but i want to keep it simple only.

you only need to backup your ta partition if you plan to unlock your bootloader. By Unlocking your bootloader you will lose your DRM keys. Anyways having a backup of your ta portion isn't nothing bad.
Using flashtool and flashing a stock firmware will not unlock your bootloader.
2]
A stock firmware comes unrooted. Pre rooted means that the firmware comes with root integrated.
3]
PRF Creator is a Programm you use under windows
4]
You have to understand what a ftf file and a flushable zip means.
Ftf files are flashed with flashtool.
Flushable zip files need a custom recovery to flash. For example twrp or cwm or philz recovery. To get a custom recovery on your phone your phone has to be rooted.

PRF Creator is a stand alone Programm that doesn't require a phone.
It only needs files as input and the result is a flashable zip you must flash with a custom recovery

No.
This zip will launch a program called aroma installer. With this program you will be asked what you want to install.
For example the description of iHackers rom says that you have to choose between stock or custom kernel.
3]
To flash a custom rom or custom bootloader you must unlock your bootloader first. If not you can't flash anything custom.
You can unlock your bootloader with flashtool. For that you need the unlock key for your bootloader. You do this in fastboot mode with the help a flashtool.
Flashing a ftf the phone is in flashmode.
Fastboot mode and flash mode are two different states you can put your phone at.

I am not sure. As far as I understand yes if you choose locked bootloader.
Maybe some other member can help here too.
But to flash the zip you need a custom recovery. For a custom recovery you need root to install it.
Post #4 at ihackers rom Threads mentions the step to flash the rom on a phone with locked bootloader. Not that easy!
Answer is Yes. I've already tried iHackers ROM on my Z1 w/ locked bootloader. I don't want to be rude or anything but all your questions are answerable by going through some basic reading materials that are all available in XDA. I strongly recommend you do your reading first. We don't want you coming back at us saying you now have an expensive paper weight, or that you have lost some important audio, video, image, SMS, MMS, Contact, etc. on your phone. It would really help alot if you read the iHackers ROM thread as well.
You did state on your initial post that you want to keep things simple. Then I suggest rooting your phone, get rid of the apps you won't ever use and just keep it stock.

I just want to answer this and sum it all up.
Do i have to Backup TA before i use flashtool? i think if i do flashtool No, you don't need to Backup your TA partition to use Flashtool. Flashtool works for both locked & unlocked bootloaders.
i will lose DRM keys like sony features? (for locked bootloader) I'll treat this as a separate question. Yes when you unlock your bootloader you will loose your DRM keys, which is why you need to backup your TA partition first before you unlock your bootloader. But as I mentioned earlier - No, you don't need to backup your TA partition if you will not unlock your bootlader. And -No, it is not needed to be able to use flashtool.
What meaning by 'pre-root' firmware? It means it is a stock Firmware that has root access. It is basically your stock firmware that was ran through PFRCreator.
without root phone and unlocked BL, is it possible to use PRFCreator? It's basically like this... NOTE: This is a not-so-details procedure but it will give you an idea on what the PRFCreator is. So the answer is Yes, it is possible to use PRFCreator with a locked bootloader but you need to have a rooted phone with a custom recovery so you can flash the pre-rooted 5.1.1 *.zip file you made, then flash the 5.1.1 FTF using Flashtool
1. Install flashtool
2. Download a 5.1.1 FTF using XperiFirm (it's an icon in Flashtool that opens a FTF downloader that automatically unpacks and makes you a FTF that you can flash on your phone)
3. Download PFRCreator
4. Using PRFCreator you basically create your very own pre-rooted 5.1.1
5. Now you have Two(2) files - the flashable *.ZIP file (the file generated by PRFCreator) and the 5.1.1 FTF you have downloaded earlier
6. You will need to root your phone and install a custom recovery partition on your phone so you can flash the *.zip file you have created using PRFCreator, then flash the 5.1.1 FTF using flashtool
7.
