hello guys. i just got these beautiful Z1 Compact last week. it's on lollipop 5.0.2, build number 14.5.A.0.270 and i want to root it, backup my drm keys, and keep X-Reality, camera quality, and all the other Sony stuff.
i've been reading the xda xperia forums, and it seems there exists a paradox when it comes to making a TA backup on lollipop (but correct me if i am wrong):
you need to unlock the bootloader in order to root the phone, in order to backup TA. But since by then i will have already unlocked the BL, my drm keys will be already deleted, because unlocking the BL causes that. kitkat users can root without BLU, though. So i've come here with the following questions:
1) is there a way to safely root a Z1c on 5.0.2, without BLU?
2)if not then, it has occured to me that i could first downgrade to KK, then root, backup TA , and finally flash a 5.0.2 PRF on top of rooted KK. is all this actually possible? how can i downgrade to KK (it is the only step i dont know how to do)??
3) is it possible to dirty flash the same firmware on top of one another, maintaining the bootloader unlocked? ( create a .270 prf and flash it on top of a non-rooted .270 fw?)

The step number 2 is the only method for now for rooting with locked bootloader. To downgrade, You simply flash a Kitkat .108 FTF via flashtool. Do take backup first though.
As for third step, it is possible to do dirty flash, but to flash You need recovery and for recovery You need root, so in a way You cannot flash PRF on non-rooted .270 FW.

I just got my Arc S, and i want to check out few different custom roms. I was planing on rooting the device with Easy rooting toolkit, so the question is, how can i backup my stock rom and reflash it, if i ever need it for warranty issues? (Also maybe to get the official 4.0 update next year )
On my previous phone (HTC Desire) it was pretty easy, by restoring the Nandroid backup that i created after rooting the device. How about the Xperia? Is there something similar?
And while we are here, any suggestion for some stable custom roms for the Arc S? Thanks
If you only want to root your device, you can simply unroot the device.
But you don't really have to, when you update your device using PCC or SEUS, the root is gone.

If you decide to unlock your bootloader to flash custom kernels/ROMs, you have to relock it, when you want to update your firmware using PCC or SEUS.
http://forum.xda-developers.com/showthread.php?t=1134335
And which custom ROM you like is your decision, but I'm still a CM7 fan.
I have root, if I want to return to stock ROM (without root) I can just use SEUS to update my phone and the root is gone?

If your bootloader is locked yes.
I rooted my arc with EasyRooting toolkit,
How do I know if my bootloader is locked or not?
Edit: I checked by the service info, it says
Rooting status:
Bootloader unlock allowed: No
I am guessing that means my bootloader is locked?

Yes, it is.
And if you root, it doesn't, mean you've a unlocked BL.
Btw, you can't unlock your BL using the official method.
If you still want to unlock your BL, contact Jinx13.
Hello guys,
Just have a quick question I am on stock sony android 4.2.2 rooted with a locked bootloader,
I was wondering now that 4.3 is out and I use flash tool to flash the new 4.3 would that cause any issues? I know I would lose my root (is there any way to save it) or can i just flash the new update with no issues.

If you flash the FTF using flashtool it will wipe the phone completely and obviously root will be gone. AFAIK the only way to root 4.3 right now is with an unlocked bootloader. You may want to try to update without wiping, it might preserve root. The update still hasn't rolled for the C6506 so I'm unable to try anything.
Dear members of XDA!
A few quick questions here:
If my bootloader remains locked from stock:
1. and I downgrade to a previous stock android version rather than 4.4, will I lose BE?
2. if I do lose it, and then flash the last stock version, will I recover it?
If my bootloader was unlocked, I know that I should lose BE, BUT:
3. if I install a custom rom, don't like it, go back to the latest stock, and after everything's finished, relock the bootloader, will I recover the BE?
Thanks in advance!
1.nope
2.you will lose only if you unlock BL.
3.if u have TA backup, you can relock BL and recover BE by flashing stock ROM and restore TA.
Hi everyone,
I just got this device recently and it's running official lollipop, I need a simple way to root it with locked bootloader?
I got the lollipop 14.5.A.0.242 tft file, can I make a pre-rooted lollipop for this region:
Xperia Z1 compact D5503_14.5.A.0.242_R1D_Customized MEA 1279-5365.tft
???
or any detailed simple way to root lollipop? "newbie"
I am stuck here and I want to move my data from another device using Titanium backup, this is way I need the root access...
any help would be appreciated..
thanks in advance..
I unlocked my bootloader(knowing I have TA backup) and used this method to root.
Then I restore my TA partition I backed up when I was still on rooted kitkat.
Working well, rooted and locked bootloader

Hello!
I've spent quite amount of time reading but i'm only getting partial answers, the big picture is still unclear since there is so many possibilities.
Currently: 14.4.A.0.108 Kitslim evo, rooted, unlocked bootloader (official method), custom kernel (Doom), TA keys are backed up with the TA 9.11 program.
Goal: Get 100% Stock on 14.4.A.0.108.
I can't use TA as first because i'm already on custom kernel which would result in bootloop.
If i flash stock rom i will loose recovery and i don't know which options i have to exclude since there is no info about that when flashing from unlocked bootloader.
How can i get out of this mess?
Thank you!

Question: what do you want?
Unrooted stock rom or another rooted stock rom or ....?
if you want a stock unrooted firmware, you must use Flashtool, download firmware first and then flash it with this tool.
Otherwise just download another stock rooted rom, copy to your device, boot into recovery and flash it

Goal is to get into condition ready for warranty.
Do i have to exclude TA in flashtool options when flashing stock rom?
When relocking bootloder do i have to use BLU or TA 9.11 program method?

all explained here
restoring TA partition will relock your bootloader and restore DRM keys, but only if you unlocked bootloader the official way by Sony.
same here i have rock z1 l, want to return to stock everything with that step i will return ??
