There's no way to fix, you have to sell it as bricked device...

Totally no way to repair it?
Good move Sony...
Edit: tablet runs regularly, I can update with companion app and everything... Just fastboot looks broken.

Yes.
Sony warns this problem in bootloader unlocking page, so read carefully before trying.
(they should change it to big red text?)
Unlocking bootloader is risky thing if you don't read warning.
Also security and encryption features often don't work on unlocked bootloader, so don't expect them to work.

I noticed Sony Mobile Flashtool give same error on my full working Z5c (ERROR - Can't read a byte value), so that should be a Flashtool issue... Maybe fixing that, I could flash and unbrick my Z4 tablet (?)

Xperia Ray locked after FOTA update

Hi first of all sorry for my poor english!
i have unlocked my xperia ray bootloader using the tutorial on the official sony ericson website losing my DRM data, and flashed using flash tool the official
ST18_4.0.A.2.368_GENERIC_(1248-9545).ftf file and all worked fine until i done the Firmware upgrade over the air and there my pone stopped working..
i have flashed another firmware but nothing
i cannot go even in the fast boot mode, only flash mode.
can anybody help me? pls
I dont think there is anything you can do. I read somewhere that happens when you unlock bootloader on official website and update it over the air. A hard brick i think its called.
Hope im wrong.

This works guaranteed
thanks a lot all fixed i was sure u guis can help me,
another question is there any way for me to turn back to official updates and using track id?
Did you even take the time to read the disclamer that Sony Ericsson has on their Developer site?
Known issues
It is currently not possible to unlock the boot loader for CDMA phones.
Some customers with unlocked boot loaders have experienced problems when they are accepting over the air upgrades (FOTA - Firmware upgrade Over The Air). For customers that have unlocked the boot loader, please do not accept any over the air upgrades. For additional information, check out the hints and tips from the community on the XDA forum.

That answers the reason you bricked your phone.
And as it has been answered a gazillion times. NO NO NO NO. You CANNOT restore DRM or Track-ID. There are other third party apps that do the same thing.
Please note that you may void the warranty of your phone and/or any warranty from your operator if you unlock the boot loader. Sony Ericsson can then no longer guarantee the full functionality of your phone, and will not be responsible for any unsigned custom software being flashed to the phone after the boot loader is unlocked. Certain functions in your phone might cease to work, and performance might not be ideal. You might also damage your phone permanently. In the worst case, unlocking the boot loader will cause physical injuries or material damage, for example, due to the phone overheating.

That includes but is not limited to: Official updates(especially ICS), DRM, Track-ID.
I'd recommend you did some research before unlocking your bootloader. It will save you a lot of time and stress.
no i readed all the disclaimer, fully knowing what i was doing. and the reason i have done the fota upgrade was only a stupid mistake i have pressed ok on the notification of update, becouse is similar with the market notification of updates, and i was only wandering if some genius in here was able to make the inverse process of the drm data thanks a lot for evrything.

Hi, I was always wondering then in such case you only shouldn't use OTA updates or does update through PC Companion would brick the phone as well? Do somebody might know the answer?
no the pc companion wont let you update, but if it dose (wich is impossible i think) it wil do same thing.. so update your phone with <flashtool only
Do you try to reflash with the stock rom??

[Q] I need a lot of advice... thanks for looking

Hi people. This is my 3rd android device. Two samsung products, and now the Z ultra.
So I have no idea what people are talking about... I'm used to ODIN... so is flashtool a similar piece of software?
My xperia Z hasn't arrived yet, Im just trying to get my head around sony and the way their devices are run..
So.. questions...
1. Backup your TA partition (I read that this has important info that I don't want to loose... Do i do this with flashtool? Do i also reflash this partition at a later date?)
2. Unlock your bootloader (Why are some people not unlocking bootloader... Do I understand correctly that some features will stop working... like x-reality?? If so, can't they just be reactivated with a custom ROM?)
3. I see there is a recovery for locked bootloaders... (can you still flash kernel's custom ROM's zips using CWM with a locked bootloader?)
Ive spent 3 days looking on the threads here, but I think because of my previous devices I have a preconceived idea of what i should be doing.. I'm confused.

Now everyone knows you're a n00b!
First of all, the minus of unlocking bootloader is losing your DRM keys. To do this, sony has provided us an official way through their website (just google it). Or you can do this via flashtool too. After unlocking, you will lose xreality engine and won't get FW update from sony anymore through official means (pcc or ota, but you can always flash). Some says trackID will be lost, too, but hey, who use it anyway?
The plus is, you entered godmode for flashing anything into your phone.
Unlocked bootloader can be relocked through flashtool, but relocked is not the same as locked, because xreality is still lost, cmiiw. To restore to original locked state, use backupTA (search thread in xda) BEFORE unlocking bootloader. And backupTA needs root, so we need root w/o unlock bootloader first (already plenty in other threads).
And yeah, what a maze this is.

Ok thanks, that confirmed what i thought about bootloader..
Can you still flash VIA CWM with a locked bootloader?
otherwise as i understand it...
1) root device
2) backup TA parition
3) unlock bootloader
4) flash ROM/kernel/etc
5) reflash TA partition.
done... custom ROM with x-reality support?

Well it's harder to make, apparently. Currently even custom recovery for locked bootloader is not finished yet. Check the development section. And flashing things that normally isn't allowed on locked does have limitations, check in other xperia devices threads.

Actually on firmware .510 with unlocked bootloader and I still have Xreality. Making your Ta backup is mainly to be able to restore your device in case of softbrick or restore your phone to stock.

I am looking at getting the phone too. From what I understand is when your bootloader is locked, it will only load signed boot partitions. So any modification to the boot partition outside of the official stock kernel will not boot when locked. So installing any custom kernel (OC/UV/etc) with stock rom needs unlocked bootloader, or installing CM (which has it's own kernel anyway). So best is getting custom roms (only modified system) with stock kernel.
Also like already said, unlocked bootloader means no updates from Sony. I would backup TA at all costs anyway.
I doubt stock kernel supports kexec, but I guess you can hack the system init process to load different ramdisks. Which is why I guess they are having trouble with locked bootloaders with recovery ramdisks in the dev forum.
I am waiting for the C6806. Here are my plans:
1. Root using vroot (hope it doesn't infect TA with something ;o)
2. Backup TA Partition
3. Unlock
4. Deal with loss of DRM
5. Install whatever ROM/kernel for daily usage
6. (maybe make official TWRP)
7. Get official updates by restoring TA partition, stock kernel if necessary
or...
1. Root using vroot
2. Backup TA Paritition
3. Stick with stock kernel
4. Help with getting locked 2nd ramdisk working with stock init
5. Is the stock ROM awesome enough? (Not sure since we don't have 4.3 )
Also hoping info comes out about ATT bootloader soon on Note 3.
LTE phone is out by 9/25 I am thinking with US warranty support. (C6806)

I bought this device in Canada, The provider is Bell.
My bootloader is locked. And following the Sony steps.. It says it won't unlock.

All my favorite apps won't work properly without root.
If anyone figures a way to root it.. I'll give you $100.

$100.... it's sounds good? Okay from my experience I bought my XperiaZ from Australian Telco before and it said Bootloader unlock allowed:No
but when I flashed official generic ftf using flashtool. It's said Bootloader Unlock allowed:Yes. So if you can take a risk try it(do it by your own! and don't forget to back up!)... you might try to do that. Luckly my XperiaZ2 is bootloader allowed one. Hope I have a chance to get 100bucks

This is very dangrous, this depends on the contents of the FTF and i wouldent recoment this at al
Have you tried flashing the German DE generic FTF, i think it has stuff for the TA partition
This may do your job
I still dont recomend, do this at your own will if you know how to unbrick a device
Although i would try it but only because i know how to unbrick a xperia (lol this part usualy takes a while)

I noticed him that it must be done by his own.... But he asks us to is there are anyway to do that? so I just posted the way I did.
I am not recommending him to do that.... I just simply answered his question. Always flash ftf w/o TA and partition.
It is recommended everywhere and If once he started to searching about flash tool it is warned by everyone.
You can't back up TA partition w/o root. So I don't think there is any way to get XperiaZ2 to back to completely stock.
(Although i would try it but only because ←What does it mean? It doesn't make sense for me.)
Well, I tried to flash the stock FTF.. same version as my devices. It errored.. and I am now bricked.
You can't modify an FTF and flash it to a bootloader locked device, modifying it will break Sony's signature verification
I'm guessing there's no way to unbrick?

Pt1
Unplug device totaly
Hold power
Hold volume up
Wait for it to buzz 3 times in a row
(rubber bands usualy help)
(ensure battery isnt killed from doing this (low charge)
(aka dont leave rubber bands for several hours)
Pt2
Download and install sony PC companion
Go to support
Go to repair device

You'll need to find Sony's signing key then. Good luck with that
Aww.... We warned you.... it must be done by your own and not recommended. Try SEUS.... (Not sure if it works for yours....
Everything what you've done with flashtool will be avoid your warranty..... I think when you downloaded flashtool they warned you again....
As EnviousData warned you too.... even I did not recommended to do that.... dear....
Ok, I managed to unbrick.. back to bootloader unlock allowed: No
Still.. If you guys have any ideas how to root.. $100.

Honestly i say keep your $$$ and wait for a exploit or root method of sorts
Me and my FTF will be a while and Z2 Development has started very slow and may be a while before anything of the sorts comes avaliable
I suggest if you realy want to root try exchanging your device for an unlocked one (or unlockable :/)

[Q] How to enable OTA updates again?

Hi guys,
i have found a few threads with same question but for other handsets so making sure to do it right.
I have got a C6833 which i rooted, unlocked bootloader and flashed custom rom. I need to send it in for repair because of some speaker issues and would like to return the device to original condition. I have flashed a Sony ROM with flashtool but obviously that was not enough, the OTA updates don't work so i assume something else is wrong.
WHat do i need to do to fully restore it? Also, what is the newest stock rom for an Australian handset?
Thanks a lot, i am sure this has been asked already but i couldn't find the answers needed.

You must relock boot loader. Dont forget your ta back up as well. This is what I would do. Relock bl hook up to Sony pcc and repair the device. It will become factory.

Thanks for that. I do not have any back ups such as TA. Is there still a way to do it?

you can lock the BL with flashtool but they may still refuse warranty - some do, some places dont.

Rooting F3213

Has anyone being able to root their F3213 single sim?
No. We need someone from xda experts to get root on locked bootloader. (f3211)

Not gonna happen anytime soon, since dm-verity security was introduced on the z3+ every Xperia since has needed a unlocked bootloader to get root there's also no way to back up ta keys currently either unfortunately. I'm sure someone will correct me if I'm wrong.

Doesn't sony's developement website let you unlock the bootloader?

Yes if it's a sim free network unlocked device not locked down by a network/carrier and its supported by Sony for unlocking. Phones that come locked to one network are usually not bootloader unlockable. I was referring to locked Bootloader root, on mm it looks like it's a thing of the past from now on
*#*#7378423#*#* enter into the dial pad and in software configuration I think it is it will say
Bootloader unlock allowed: yes or no, if it's a yes no problem get the code from Sony via email and unlock(it voids the warranty though), if it's a no you won't be rooting it.

Make sure my Xperia is off and OEM unlock in developer options is on, also once the drm/ta keys are gone on unlocking there's no getting them back as there's no way to back up ta keys currently on our devices before unlocking which is why I'm waiting for now.

You are almost right. The only part I disagree with its that you said it will not happen any time soon. While dm-verity make it impossible to modify the system and permanently root it, if a proper exploit is found (which happens almost every month) the system can be temporarily rooted. When that happens, the TA partition can be backed up and the bootloader can be unlocked for permanent rooting. That's actually how z3+ is rooted.

You really make me laugh!! Almost one exploit by month ?! The exploit used in Z3+ was discovered in 2014 (the one used by Kingroot) !!! And patched since 3.18 kernel. Since when dm-verity on Marshmallow was beaten without downgrading to an old exploit on Lollipop?? Can you prove me that's possible to dump TA in MM. Answer me just to laugh a little more :good: See you next month for a new exploit
For me aidy.lucas is fully right!

And to finish, if someone want XA Ultra single sim root please PM me for private tests. You must have unlocked BL and have enough skills in flashing Xperia devices to help.

F3213 - Bootlooder
Hi,
I purchased a F3213, single sim that was carrier locked, no way of unlocking the bootloader.
So after hours of searching, found a fellow in England who offered me a tool to make the phone bootloader unlock ready.
The Phone now works with another carrier, if i unlock the bootloader will i loose the DRM keys?

Unlocking it to work on a different network still won't make the bootloader unlockable. If it's been locked down by a carrier/network it'll stay locked even if the device will now work on any network.

If you can unlock bootloader, root is possible. Download the rootpack for your model and follow the guide for XA, read comments if needed. Read carefully the "unlock bootloader" part to be aware of what it does.
So if I root my F3213, does this allow me to get rid of all the crapware Sony put on there? Or will I need to flash a custom ROM in order to do that?

You don't need to flash a custom ROM to remove most of the system applications. If you have root you can use Titanium Backup to eliminate those unwanted apps.
I haven't rooted yet and just using the disable function in the settings/apps I've gotten rid of almost everything except the What's New thing. With that I just blocked the notifications and it doesn't bother me.
Hey guys. I have a question. It seems that in sony's android MM version, microsd cards can't be used as internal storage. I had in other rooted phone the Link2SD app just to expand my internal storage. On XA Ultra we get only 10Gb free, no root no unistalling trash apps, sooo, any way to expand it via sdcard until root is available?

MM have a feature called Adoptable Storage, you can find guide on Xda. Simple way is to use "root essentials" app on rooted device or with ADB command on not rooted device.
