[Q] Confused about keeping DRM & BE2

Hi there, ive came all the way here from the Defy turf and im really confused about flashing my new xperia z. ive tried my best reading the tutorials but it seems to be alot harder to flash the xperia z with proper backup, i mean i used to flash my Defy pretty much everyday without worrying much.
So my question is very basic.. btw I have root my xperia z through the "[Exploit by: goroh_kun & huhka_com]" method, and the bootloader is unlocked.
1. Is it possible to backup my unlocked stock Xperia Z with DRM & BE2? i know there are both twrp and cwm, but ive heard that once I "flash" my phone I will loose everything even with the SD card... (i mean when u talk about flash, there are tons of file types u can flash such as img, rar, zip etc and also tons of ways to flash, so which way to flash is the best without loosing eveything?)
And if yes, is there a step by step guide about how to use the flashtool? (i know there are million posts about what a flashtool is, but what i need is a step by step on how to install/flash cwm or twrp on an unlocked stock xperia z with DRM & BE2.) I mean I would like to be able restore if I dont like the custom roms.
2. does upgrading from the Sony update wipe out all data? i mean for the future 4.2 update can I just update without loosing from what I have at the moment (an unlocked and root stock xperia z)?
sorry to ask all these basic questions, but ive been searching alot with no clear answers...
thanks!:good:

uh bro. as soon as your bootloader is unlocked, DRM keys are GONE FOREVER. Unlocking your bootloader wipes everything too. by everything i mean your photos, music etc as well.
secondly, some updates might wipe data, and some don't

thanks for the reply. but i dont really understand, because I still have BE2 and track ID working, how do I check if I still have my DRM keys? i know i have an unlocked bootloader through *#*#7378423#*#* but i dont remember unlocking my phone apart from using the [Exploit by: goroh_kun & huhka_com] method to root my XZ. Can a XZ come unlocked from a Sony Retail store?

You're not confusing unlocked and unlockable are you?
The only way to unlock the bootloader that I'm aware of involves getting an unlock code emailed to you from Sony via their official unlocking website.
While the bootloader is unlocked you will not be able to update to a new official Sony ROM either OTA or via their provided PC/Mac software tools.
Locking & unlocking the bootloader is explained clearly here:
http://forum.xda-developers.com/showthread.php?t=2153261
The bootloader will be locked on all new, unopened XZs
regardless of place of purchase, a phone purchased from Sony will (should) be carrier unlocked however.

Now I get it, so I simply have a rooted locked (but unlockable) Xperia Z~
it looks like everything makes sense now:good:
Thanks so much!
just one more question, does twrp or cwm recovery backs up everything including drm keys BE2 and etc? or do I have to go through this? http://forum.xda-developers.com/showthread.php?t=2234627

nope, recoveries dont back up your drm keys.
you have to use the Backup TA tool that was posted, this one
http://forum.xda-developers.com/showthread.php?t=2234627
Remember, ALWAYS, MD5 sum check before flashing, flashing someone else's or corrupted TA will HARD BRICK your device,

[Q] Re-lock bootloader xperia t lt30p

Hi, I unlocked the bootloader on my xperia t lt30p one time with intention to root it and install custom roms but never did as I nearly bricked it when putting a kernel on. I managed to put what I think is a stock kernel and rom back on, but I went to update it the other day and pc companion says that it could not complete the operation because the phone has been modified. I read somewhere that having the bootloader unlocked can cause this, so I wish to re lock it. Could anyone point me in the direction of a good tutorial to do so? Cheers...

the link provided by our friend is quite good, that's where you have to head over
and about the tutorial, tha't so easy, just flash that FTF file via Flashtools
power off your phone, open flashtools, select flash logo, then FLASH MODE, then connect your phone as you are pressing down the VOLUME DOWN button, and let it do the rest
disconnect and enjoy your relocked bootloader

So I won't need to re flash the rom again? sorry. I'm a bit of a noob at phone modding. Pc's I can do. Not phones yet. Hahaha.

no, flash the relock ftf found in the dev section, and it just relocks your bootloader, your rom will stay the same

RElock won't affect you rom, BUT if you unlcok AGAIN, then at the very first start up of the phone when it is the first time after RE-UNlocking, it will have a factory reset
just wanted to let you know
but for now, NO, it won't touch your firmware

Just done it. Worked. Cheers guys,

[Q] Rooting issues - 4.3, IMEI, not actually rooted etc....

Hi All
So firstly I should say I only have myself to blame. I'm quite a techy guy so I just assumed i'd be able to root my phone without any issues and pick it up as I go. What i've quickly found out is i'm in way over my head and i'm an absolute noob!
Any advice would be greatly appreciated from those guys out there that actually know what they are doing. I have read many forums but i'm still lost.
My story is as follows:
- I have a Z1 that was locked on stock firmware 4.4
- I read that it would be a good idea to unlock the bootloader so i did this
- I wanted to root my phone but from what I read I could see I would have to downgrade the firmware to 4.2. So this is what i did.
- By doing this I lost my IMEI number, got very worried i'd ruined my phone. I tried many things to restore it, there were a variety of different solutions online, none of them worked. I eventually flashed a 4.3 firmware i found on this forum which restored my IMEI.
- I then read through a few posts of people who had similar issues and advice was given to downgrade again (if i wanted to root) but this time exclude the baseband etc. I did this, but lost my IMEI again! the advice didn't work
- So I then went and updgraded again! to 4.3 to restore my IMEI and network access
- There doesn't seem to be a way to root on 4.3 so my phone isn't rooted, that's ok. But when i try to use my banking apps they don't work! they say my phone is rooted even though it isn't! I have checked with root checker
- Like an idiot, i didn't back up the phone when i first started doing all of this, i didn't really know what i was doing so I am now in a situation where i have the worst of both worlds. They are, i can either 1. downgrade the firmware to 4.2, root my phone but not have a valid IMEI and network access or 2. stay on 4.3, have a valid IMEI and not be rooted but certain apps think i'm rooted so i can't use them.
So all in all i've just messed things up and i'm in way over my head. I would really appreciate some advice
Thanks

Yes you are right.
Also, there is no issue with losing IMEI when downgrading, it happens to everyone, but it comes back when you upgrade.
Also, if you unlock the bootloader there is no need to downgrade, that is a locked bootloader method of rooting
You should root before unlocking the bootloader in order to backup the TA partition, but you are too late now...
Solution
1) Use flashtool to relock the bootloader
2) Use pccompanion to update to latest firmware
3) Unlock the bootloader again with flashtool
4) Flash a custom kernel for stock based ROMs
5) Install SuperSU from the play store.
DONE!

I don't think so, the unlocked bootloader method is very generic and there are hundreds (if not thousands) of guides and probably as many videos.

Hi Greg, can you give me a bit more advice please.
i'm just looking at the tutorial to relock by bootloader. It says "before u relock bootloader u have to be on pure stock kernel (flash only the kernel.sin using flashtool), else the device WILL NOT BOOT after relock"
The problem is i'm already flashed on to an FTF image that was on this site. From so by doing this am i going to brick my phone? i'm confused and i don't want to make things work so your advice would be apprecaited
thanks

NO. You can't unlock your bootloader if 'unlock bootloader allowed = no'
Since you cannot unlock bootloader, therefore you cannot flash custom ROM on your phone.
Rooting phone do not always need bootloader to be unlocked. There will be some ways available to root your phone with LB.
Also there will be some ROMs available that can be flashed over LB. But they'll be based on stock and will not have more features rather than stock features.
You just need to search here on XDA
I suggest you not to flash any ROM on LB. You'll eventually get bootloops and maybe hard brick.

Nope! As much as I know, you cannot change status from 'no to yes' rather than changing your motherboard to do so. It'll cost you more than you buyed it.
It is related to TA Partition. And EVERY phone has its unique TA. So no one can change its status. Flashing other phones TA to your phone will brick your device.

In such case you need to roll back to your previous android version. I don't think you could unlock your bootloader. But if you are telling it was 'yes' before, then you should try.
No matter your phone works with every sim or not. TA Partition contains DRM keys as well as many other things related to network, warranty, services which get erased after unlocking bootloader.

Yes you can flash any stock ROM through flashtool. You just need to download appropriate firmware (.ftf)
Even you could update your phone through PC Companion. The latest version is 5.1.1 Available.

You mean bootscreen, right?
Just because of bootscreen are you going to change the entire ROM?
You could change bootscreen manually. Your phone just need to be rooted to do so. To root your phone use kingroot app. If your lucky enough, your phone will be rooted.
There are tons of bootscreens available. Just pick one and place it in /system/media (don't forget to backup old one) with -rw--r--r permissions and Bingo! You have changed your bootscreen.

Try the same app several times. It usually does not succeed in first attempt. It you fail each time, try kingo root with windows software.

Dude, your on latest android version. There isn't any exploit available to root ver 5.1.1
You either need to wait until anyone makes an exploit for your phone or you need downgrade your phone and root it.
There is a pre-rooted firmware available for lollipop But it works only if phone has 5.0.2 .
Unfortunately your phone has 5.1.1 that means you still need to downgrade your phone and flash pre-rooted 5.1.1
Also, your bootloader can't be unlocked. So you need to flash ROM accordingly. Don't ever flash ROM that are meant for unlocked bootloader.

This will open the service menu, check under general service info (if I remember correctly). You'll find there whether or not your bootloader is unlocked.
Download flashtool by androxyde and the rom you want to flash (you'll find it here on the forum) and flash it via flashtool.
If your bootloader is unlocked, lock it with flashtool (though it won't make any difference as I'm pretty sure you didn't back up your DRM keys)

and in that service menu it says
bootloader unlocked allowed:yes..

It means your bootloader is unlockable, but currently locked. You do still have your TA partition and DRM keys. To install stock 5.1.1 you can also use sony pc companion, it should be the easiest way. All your current data might be lost, though
