Problem with recovery z1 Help please.

Ok so i've made a mistake, fortunately I can still use my phone but i'm in unfamiliar territory.
What I did was download the 4.3 Rom by RomAur, installed the rom and the recovery as per the instructions within the thread, then rebooted to flashmode and entered flashtool so I could flash the kernel and baseband from 290, but made the mistake of excluding kernel and baseband and flashing the only other option which was BOOTBUNDLE, and since then my recovery has been inaccessible.
I've reflashed the dual recovery but it won't allow me to access it via the power on up or down method or the adb reboot recovery method.
I really can't continue with this phone or flash anything without a working recovery, does anyone have any idea how to get my recovery back please??
Any help would be appreciated.
I'm also wanting to unlock the bootloader but without a working recovery i'm a little hesitant to begin.
Phone: Sony Z1 C6903
Rom: RomAur v4.0
Bootloader status: Locked

Flash the kernel and baseband from 290 in flashtool then.

Well i've gone and downgraded but used an unbranded ftf, which has now taken over my IMEI, which now reads 0000000000000000.
In a bad way here and stuck in work with limited internet, i'm now back on a 534 rom and feel like smashing this thing up.
Going home soon so will sit down and go through it all again from scratch, wish i'd just left it on my old monx rom now.
Bad times.
Any other ideas Greg ? Or anyone else?

just upgrade back, I believe you get your IMEI back that way..
The problem you are having is that you need unlocked boot to get a properly working recovery and root on 4.3

Ah i see, well i'm downloading an ftf which is t-mobile 534, it's the closest thing i could get to EE, as at the moment i have no recovery and no root.
So should i do this in this order.
get this tmobile 534 and re root and get recovery, i imagine at this point my IMEI will still be missing (hopefully not) then what would you do?
Update to 4.3 by using one of those roms? and then unlock the bootloader? As thats where I ended up losing recovery, i'm thinking thats maybe down to me flashing boot bundle instead of kernel and baseband through flash tool.
Also doesn't unlocking the bootloader require system rw access?
And thanks by the way Greg, i appreciate your help.

Same thing happened to me. So I flashed Nordic 4.3 kept my data booted then flashed the kernel that comes with twrp. So far everything is great

1) Update to 4.3 using a FTF of your choice.
2) Unlock bootloader (This will wipe system and internal memory so have a backup of internal sdcard)
3) Flash any of the three kernels from the top of this post, I am using the third one with philz recovery.
4) enter recovery and flash the SuperSU.zip found in that same post.
Done.
You do not need root to unlock bootloader. The kernels have the recovery incorporated into them

How do you flash a rom without a recovery though? sideload? Not sure, but nevermind, i ended up doing what i said i was going to do and now i'm back online and have re rooted but still on 4.2, will probably stay on 4.2 until 4.3 is 100%
Not being able to use things was too much of a pain in the arse.
Cheers by the way m8

Ahh that sounds simple enough, cheers m8, well i'll maybe give that a whirl as i'm at home and obviously my internal has been wiped anyway, got a back up in work so i'm running on minimum until i go back there.
While i'm in this state i may as well give it a go.
Cheers Greg, will let you know here if it worked out.

Well i've not attempted the unlock because after following the instructions it says in my phone that my bootloader cannot be unlocked.
I downloaded a vodafone UK ftf if that makes any difference, i got my phone from EE.
I noticed that you said to someone that they couldn't unlock the bootloader if it said that? Is there no way around it?

Bootloader Unlocking Allowed: NO
You can't unlock bootloader. Is impossible and no confirmation if even will be in some "unofficial" way.

Is there any solid data on how/why some Z1s cannot be bootloader unlocked? I have a C6906 from Overseas Electronics which I think was sourced from Canda and cannot be BL unlocked, though it's sim unlocked and otherwise works fine on AT&T LTE.
I found a thread/post here mentioning that Sony may be able to "fix" these devices (and possibly for free, at that). I'm going to run down that angle, but if there's any technical data on what could be preventing the BL unlock I'd be very interested in doing some legwork on my own.

Not too sure mate, think its coded not to be unlockable, in which case someone would have to do quite a bit of digging to undo whatever was done. And seeing as that the vast majority of people knew to buy from a source that doesn't have the NO to unlocking the BL I would say that its not going to happen any time soon. I usually do a bit of digging before I buy a phone, rushed into this one and I'm paying for it now.
I'll check out that link you put up, maybe there's hope yet.
Edit: as for the link you put up, that's just for the sim lock.
If you want an unlockable phone then you'll either have to claim from a 3rd party insurer an hope that they give you an unlocked phone or contact Sony for an RMA and hope that they give you one. Otherwise I can't see it.
But in all fairness your missing custom kernels and aosp type ROMs. Most everything else will work fine, including all (well most) the ROMs that are in the android development section, so that's not a total loss by any means.
When roots fixed completely for 4.3, well see more.

Xperia LT30at: Root, Unlock and Remove AT&T Apps?

In general, I would like ask about unlocking my Xperia LT30AT. I've unlocked a phone before but it has been a long time.
I seem to recall that when I unlocked my first phone, I downloaded a developer kit that you use to root and unlock the device. I am interested in doing that to my LT30at, but I don't want to use any custom roms like Cyanogenmod.
What I would like most of all to do: to
(1) root and unlock the phone,
(2) keep the (functionally) authentic Android OS, and
(3) Get all the AT&T apps off the phone for good.
...but I would settle for just the first one, for starters.
Any suggestions? Thanks! MX

it's interesting to me for the same model lt30at.
In addition I wanted to know if you lose your 4G LTE Thanks to all who respond
* P.S. many links to files in the root of the sony t is no longer usable

To root this device you should use the flashtool, you can't unlock bootloader at all. Me I rooted it added a recovery. Then flashed a unbranded firmware via the. Recovery. Kept root that caused everything to work pretty Ok now my att TL is rooted with 4.3 with a few bugs

Since you want the phone to be rooted, you have only 2 options:
1) If you want to stay on 4.1.2: flash any generic 4.1.2 FTF using Flashtool and exclude the baseband in the process, then root the device.
2) If you want to upgrade to 4.3: follow the guide in my signature.
Bootloader cannot be unlocked.

If you update to 4.3 using Flashtool you will lose root access to the device because there is no exploit available yet. Carrier lock is SIM lock and is managed separately from ROMs.

Are you sure it's "bootliader unlock allowed: yes"? LT30at have always come with locked bootloader.
Carrier lock us SIM Lock. As I've said before it's nit affected by any kind of flashing. It's stored in a different location.

Yes , Bootloader unlock allowed in my device is YES . Firmware is 9.1.F.1.120 , android 4.1.2
So can i update my device to 4.3 ?

You're probably the first person I've seen with a TL with at&t firmware (I'm assuming since it's 120 firmware) that has an unlockable bootloader.

Yea I must 2nd that how did that happen

Need help...!! camera functionality not working after unlocking bootloader

1stly i have 4.4.2 (.757) running on my z1 and i downgraded to .534 and i rooted the device by vroot and backed up the DRM keys successfully.. and then i flashed to .290 and unlocked the bootloader by flashtool and then downgraded to .534 and then installed the dual recovery and then flashed using the flashable recovery using recovery and then i found that camera is not working properly.. camera is opening and when i press the shutter butter its trying to focus the area and after focusing it freezes and doesn't shutter... so this is my problem... please help...

So much fail.
Do not use vroot, it sends your imei number to an ip address in China.
Also, unlocking your bootloader on 4.2 will break your camera, it clearly says so on the Sony official site about unlocking your bootloader.
Now, the solution.
Restore your ta partition.
Use pccompanion to update to the latest firmware
Unlock your bootloader again
Flash a custom kernel of your choice
Install super user app of your choice

I have to ask
Why are you unlocking your bootloader? What have you done it for? You do not get a recovery mode just by unlocking the boot, you have to flash a custom kernel with recovery in it
You either do all the downgrading and install dual recovery if you have a locked bootloader
OR
You unlock your bootloader, flash a custom kernel with recovery and install super user app
there is no need for both approaches and that's why you are getting problems

Why did you unlock the bootloader? What did you want to do with it?
You can not install a recovery without a custom kernel, xperia devices have no recovery partition, it can only be installed by pushing the ramdisks to the system partition or by flashing a custom kernel.
Please follow the advice I gave several posts ago.... that is your solution.
Then spend some time reading up on xperia device flashing.
1) Xperia devices have no factory recovery or recovery partition
2) Unlocking the bootloader is the fastest and easiest method to root and get recovery (If you are allowed to do it)
3) If you cannot or do not want to unlock the bootloader, then go through the downgrade, root, dual recovery process...

Greg said fifteen times - follow his guide for here.
Yoy can't flash custom kernel especially not fastboot custom kernel on locked bootloader.
Whole purpose of unlocking bootloader is to flash custom kernel.
You are confused with all this informations, I would recommend that you read few things here on XDA to understand terms and other things.
You could seriously damage your device with just one wrong step.

Thanks. I wasn't sure about this as my old xperia play barely got any software updates. Duh. It was released with Android 2.3.3 and left at 2.3.7. Since the Z1 is really powerful and custom kernels don't really give that much of improvements or actually useful features (d2tw drains the battery like crazy) then I decided to stay on stock kernel with LB to keep bionz and other stock features.

As you're still using a stock based rom, open the dialer and type *#*#7378423#*#*
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)

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
