Successfully unlocked my bootloader this afternoon on my Verizon r800x. :good:
After rebooting, I stupidly accepted the OTA update, apparently didn't pay attention to the warnings from the Sony website. :silly:
Now I've got a nice brick.
My phone won't boot.
I can't get back into fastboot by holding the search button.
I CAN get into flashtool, but reflashing the stock FTF doesn't seem to help the situation
Any suggestions?
try unlocking again/downloading fastboot drivers? Sorry if this doesn't help, I don't know too much.
I appreciate the suggestion, but like I said, can't get in to fastboot mode on the phone itself. Don't get the blue LED. Wouldn't think that would have anything to do with drivers; Windows doesn't even acknowledge a device being plugged in while I hold the search button, but as soon as I let go, I get the GREEN LED and I can use flashtool.

Edit* Typing mistake
It doesnt matter if the xperia play drivers are installed on your pc. If the blue light doesnt turn on when your powering your R800x your fastboot is disabled. That means your bootloader is still locked.

I appreciate the suggestions, really, I do, but I think you're kinda missing my point here. Whether the bootloader remains locked or not is not the issue at the moment.
The official sony instructions I followed when I unlocked it had me put the device into fastboot mode. It worked great. But now, specifically, step 12 no longer works.
ALSO, my phone won't boot, which is the actual problem I'm having at the moment.
So, my phone won't boot, AND my phone can't connect to fastboot in order to flash a new kernel or whatever else I might need to do to unbrick my phone. The ONLY thing that works right now is flashtool. Flashing the stock Verizon FTF with flashtool did not remedy the situation.
Does anyone know how I can get my phone back up and running?

It is not possible to relock your bootloader in most cases, but this may be worth trying. http://forum.xda-developers.com/showthread.php?t=1134334 There is a link to an ftf file you can possibly flash to relock the bootloader then reflash back to stock.
If that fails, chances are you have a damaged bootloader and/or TA (trim area) due to the failed update. This link may help you. http://forum.xda-developers.com/showthread.php?t=1252019
Here is another link as well by wedgess, I think he uses the same method as in the link above. They will both most likely log into your computer using team viewer to resolve your suspected TA/bootloader issue. Read the entire thread, but wedgess's post is #27 http://forum.xda-developers.com/showthread.php?t=1957328&page=3 . Good Luck...

Your wrong using ftf will not relock your bootloader.

Did you back up your trim area? Because you have damaged it and will need a repair contact allejandrissimo about a bootloader and trim area repair... you can contact him at http://unlock-bootloader.com/

Have you tried flashing a different ftf? I have the R800at, and I couldn't unlock my bootloader until I flashed a generic R800a ftf. I reflashed to the AT&T R800at after the bootloader was unlocked - no problems. Think you could flash an R800i ftf just to get back to a bootable state and then flash the Verizon R800x ftf?

Yeah, I posted it more for reference than a solution...hoping it may let him know why flashtool can't fix the problem. The problem is most certainly the TA which is why I posted the other links.
Fixed.
I flashed "Xperia 2011 Range_FreeXperial_ALL.ftf" upon the suggestion of alejandrissimo. Rebooted, and in fastboot as I type this.
Thanks to everyone for their input, but the real thanks go to alejandrissimo for the solution.

Hi Friends,
I'm trying to unloack my Z1C using the latest verson of flashtool and after connecting it in flashmode it will not display the window showing model numbers and display a window asking to switch off and connect again in flashmode.
I've tried it on 3 PC's, still not unlocked the Bootloader. What is the difference between unlocking bootloader from Sony official method and Flashtool method. Please guide me.
Regards
Shashi
Iirc the first unlock has to be done the official way, then you can (re)lock using flashtool. And the correct drivers have to be installed of course.

I want to return the device to stock and read on the sony dev website you have to flash a firmware but I do not see the Z5P, is there any other way?
thanks,

Is there a reason why you need to relock the BL? According to Sony, there is no way to restore an unlocked BL.
Q: If I change my mind later on, is there any way to restore my device?
A: No. Once you have unlocked the boot loader, you will not be able to revert the device back to a locked or original state or restore the DRM security keys. You can however use the Flash tool for Xperia™ devices to flash a generic Sony ROM, although it will not receive automatic software upgrades.

Thanks but the Z5P does not come up as a supported device for the flash tool yet, so I guess the answer is no

You can relock it using flashtool. Just choose Xperia Z5 when the device window appears. I've already tried it, works like a charm.
Not sure if you can relock it without the back up drm keys. Since there isn't a backup program yet I would assume you've already lost the drm keys. I'm afraid you won't be to revert back to the same. Camera quality and x reality will be affected.

OK i have found flashtool and click the x, but when when the device reboots and the device chooser comes up, there is no z5p to choose from so just to confirm we use z5, correct?

Some important things before you attempt the relock:
The DRM keys will not be restored after the relock.
You have to reflash the entire firmware or just flash the stock kernel before relocking the bootloader.
The phone should be on stock kernel, if you try to relock it with custom kernel the phone might brick.
Click BLU in flashtool and follow the instructions.

Turn off the mobile.
Press the BLU button in flashtool.
Press the volume down button of your mobile and connect it to the PC.
A pop up window will open, select Xperia Z5 (Z5P is not listed yet).
Another window will open, if you see Relock, press it, the bootloader will be relocked.
Let the process be over, then restart the mobile.

Relocking Bootloader
I had to unlock my device's bootloader to downgrade it to marshmallow because of the WiFi issue in Nougat, so i did it and didn't backed up the DRM keys(i didn't knew i am supposed to do it. It wasn't mentioned in the tutorial i was following or i missed it). Anyways now i am on marshmallow and i am unable to update it VIA xperia companion. It complains that bootloader is unlocked. Now if i lock the bootloader will xperia companion will work ? What is the affect of the lost DRM keys ? And if anyone knows the WiFi issue is sovled or not ?

Can confirm I did the same thing and forgot the keys (new to Sony devices vs. Google). IF you use the XDA FlashTool, you can re-lock the bootloader and Xperia Companion will recognize for a Factory reset of your device.

Did you restore the DRM keys from Xperia Companion or at least retrieve all the functions that DRM related (Xreality, Bravia engine ... )
Hi, I just got a new XZ2c and it's a pain to go through all the updates one-by-one manually, it looks like it will be like two dozen update/reboot cycles or something. I tried updating with Xperia companion by doing repair but that fails with an error. I tried xperia's flashtool but that claims my phone is locked, which it's not because I tried putting in a sim and it works.
So I'm not sure if I'm out of options.
Thanks much for any advice!
