Thanks! I just have one last question, and it makes me feel pretty stupid to ask it, but what do I do with the driver files once I download them?

I only have a zip of various catalog and information files, and no executables, and I have no idea what I'm supposed to do with them!

******DISREGARD THIS, I dragged the files into my "sony" program file drivers folder and everything appears to be working now.************

How i can downgrade 4.2.2 without losing my data?
[Xperia Z1 General] xasbo:
Uncheck DATA under the Wipe section in flashtool. userdata.sin will be removed from the content list. wrong...
[Xperia Z1 General] Rikimaru 117:
I do it but my device keeping reboot?
[Xperia Z1 General] cajunflavoredbob:
You can't do that or it will boot loop. There is more than just app data in the /data partition. The ROM data is there as well for various options you change or settings you tweak. OTA updates are scripted to wipe or transfer the old content into the new ROM, but you cannot do this in reverse.

Backup your apps and settings with Titanium Backup, flash the old ROM with the data wiping, then restore your apps and data when the old ROM boots up.

How do I know which FTF file to use? I dont see another GR one or one with another software ID for a c6903 R4B device..... (14.2.A.0.290 is what I have atm)

Will my device brick if I flash a different region one?
[Xperia Z1 General] xasbo:
You should be able to use different regions/carriers without issue. As far as I can tell, the region/carrier will have appropriate language/APN changes, I have not read about anyone bricking from this. In any case, you'll only soft brick, which is easily recoverable. If you're downgrading, make an external backup of stuff you don't want to lose because it won't persist through the downgrade.

---------- Post added at 05:38 PM ---------- Previous post was at 05:36 PM ----------

Sorry, my instructions were wrong. You should be able to flash back to the version you were on (290?) without losing your data so long as you deselect DATA from the Wipe section again. The phone should boot again and you can make whatever external backups you want. Since you don't have root it will be limited. Depending on your goals, it might just be easier to stick it out on 4.3.
[Xperia Z1 General] deli pastrami:
Ah I see. Thanks for the info.

When I downgrade the firmware will I lose DRM?

Essentially I plan to

1)downgrade

2)root

3)backup TA

4)unlock

5)put rom

6)????

7)profit

is this a sound strategy?? or is unlocking not even really necessary.....

Thanks again
[Xperia Z1 General] kaivalagi:
Unlock when you need to....I'm not a rom developer so am not in any rush and 4.3 had just arrived giving easier rooting I think so I would say wait a while until good kernels and roms are available if you're not making any yourself....just my opnion...
[Xperia Z1 General] xasbo:
[MENTION=272809]kaivalagi[/MENTION] is right, it's not a big deal to unlock now unless you really want to go play with custom kernel stuff. At this point, LB can run stock kernel pre-rooted ROMs, which is just about all the average user needs for now. 4.4 is right around the corner for this phone, it seems, so 4.3 is almost a distraction until that arrives.

As for DRM/downgrading, I downgraded on LB C6906 from 290 to 257 with no DRM issues. The TA partition tends to only get messed up when you unlock the BL, so unless you're really going to do that, you should be fine. However, make a backup when you have the chance anyway, so you have it. If you decide to flash a stock kernel pre-rooted ROM, then you can restore your TA and all will be well.

Downgrade i.e flash a .534 ftf from here:http://xdaforums.com/showthread.php?t=2469191, via Flashtool. Then root and do TA Backup (see OP) before you do anything else!

Afterwards you can update (you'll loose root if you upgrade via Flashtool or PC-companion).

For to unlock you BL you have to flash A .290ftf (no OTA). For more (and newer information than I've got right now) search the Forum.

Sorry, when I'm wrong. But that's what I found here on XDA. So I was off the opinion, flashing an unbranded .290ftf wil give him the possibility to unlock the BL. Thanks for correcting me!
[Xperia Z1 General] xasbo:
In case you don't realize why: some carriers are sending out phones with the bootloader unlock disabled. Flashing the generic 290 FTF will remove the branding, but won't change the bootloader unlock status. There is no solution yet to fix this (some people have just been returning the phone).

I haven't seen that one specifically, but obviously the rooting software is going to need to push software to your phone in order to execute the root exploit. That's *probably* what this is, but I would make really sure you downloaded a legitimate copy of vRoot.

Hello guys. That is my fist post btw, i am completely new. I think i am in a very bad situation. So here is the problem: I did follow the guide of NUT step by step by watching the video of shem in Youtube. In the end where i was supposed to transfer the flashable zip to the external SD Card i did not because i actually didnt have one in my Z1.

So now i find myself in a position that i did a factory reset, swiped all the data but i did not have a firmware in it. So it does not has any OS. The only thing that i am seeing when i press the power button is the SONY logo and nothing more. It does not do anything else. I think i also can not get into recovery mode either.

Edit: I manage to go into fastboot mode with blue led. I see it also on Flashtool, but i do not know what i am supposed to do now. Any help or suggestions would be appreciated.

So from what I have seen though, aren't the methods (Kingo, vRoot, 360root) listed in the original post all malware that have been "sanctioned" by XDA? I'm just trying to figure out if I can root a Z1s from Tmobile so I can delete the bloatware and maybe install a tethering app, that's it. Nothing fancy, as I have never rooted a phone before.

And just make sure I understand, a bootloader is what allows the install of a custom OS, and root is simply an "Admin"-like account for the current OS?

Put your phone in flashmode, Flash .534 firmware in flashtool, then root, install recovery, do a factory reset without full wipe, put flashable zip on the phone, flash it in recovery and then without rebooting flash stripped ftf with Flashtool.

Is there any other way that I can safely root my unit?

[Xperia Z1 General] howie040:
What worked for me was to flash stock ftf (.534 original from the general forum section, not the stripped ones) using flash tool. Load up the rom in flashtool. Then a a screen pops up that you should connect your phone using volume down and plugin the cable. Flashtool should copy some files (this can take a 10 minutes as original rom is +500mb).

-Then when it boots up: turn on usb debugging and allow packages from other locations (not sure if this is required).

-Root with Vroot or other tool.

-install recovery (NUT's windows-package worked for me)

-Now you have .534 rooted and could flash a custom rom/zip using recovery (.290/android 4.4/or whatever you like)

Hi guys ! First, excuse me for my bad english i'm a french student :). So. I've got my Z1 1 week ago and I want to root it. (I have a Ion before wich is rooted unlocked with tons of modification , I love try new things on my devices ;). ) but this time I want to keep my Z1 locked to still have Xreality and Warranty service. But I want full root and i'm on .290 I have think about it this weekend and I have an idea but I dont know if it can work, I will explain this and maybe you van answer me.

Step 1 : Downgrade to get root with 360 or vroot.

Step 2 : backup TA partition to relock bootloader after

Step 3 : backup SU in system to keep it with OTA, this will give me partial root right ?.

Step 4 : Unlock bootloader to access full root.

Step 5 : relock bootloader using TA backup.

Voilà ! Does this method can get me full root on .290? Thx :)
