After you have unlocked the bootloader, you don't get support from Sony anymore. Also OTA-updates are disabled. So I assume that your 'Sony bridge for Mac' (whatever that may be) also supports only locked devices.
You have to use flashtool, like you did with the 402-firmware.

Did you discover CM's Theme Engine? There you can install various themes via the Play Store - just search for 'CM11 themes'. There are white themes, black ones, colorfull ones, Lollipop-Themes etc.

Thanks for your reply that cleared it up
Sony bridge for Mac is Sony's official app
i found the latest firmware in ftf and i'm gonna use the flashtool to upgrade again !
Yes i saw them but i like the sony ui much better...i also found some mods for the cm11 that make it like sony rom but i can say that my tablet screwed it up and i had to reinstall cm11....
Anyways thanks again !

Hmmm but what if i relock my bootloader ?

That's unrelated. You can use flashtool to update, see the sticky in the dev section.
Have you tried updating your .fw OTA?

Flashtool.
Nice, you have brown phone. Remove battery and check on sticker on phone, most likely you will see prototype
you can try with SEUS, I don't expect it to work but you can try.
Don't know if flashtool supports brown phones, I would first ask creator of flashtool. I expect it to work, but ask first
if it says prototype, I would first check what fw is on the phone, is it branded, what region.
some prototypes can die if you flash new fw on them.

Well, not really a big worry. Some people want to have prototypes
Prototypes, from phone models which actually released, meaning you can find that phone model in store, can sometimes be final products, meaning even though they are prototypes, they can be flashed and used like other units. I have one W715, it's final version of prototype, so it can be flashed, but it wasn't in store
Prototypes, from phone models which aren't released are more likely tricky, it need to be careful with them.

If it's working as it is, and if it isn't branded fw, I wouldn't mess with it

I solved my problem and upgraded to the official JB using PC companion. You can get your device upgraded by following these steps:
- Root your device using the Flashtool (you will find it here in the forum)
- Using the root explorer in the ES file, change the file /system/build.prop file as mentioned here: http://forum.xda-developers.com/showthread.php?t=2249238
- Restart and check updates. You will get a notification that JB update is available for your device.
Best,

[Q]Sony Update Center

How does the Update Center app work? I found it quite unreliable. Someday it shows updates, some other day it doesn't.
I have hard times trying to figure out why it sometimes does work. Is it region dependent? Is it bootloader unlocked/locked dependent? Maybe it uses somehow DRM keys?
Even after I did a hardreset with relocked bootloader the Update Center doesn't show anything.
It's obvious that I may download the new apks for Walkman etc. from XDA or Xperia Blog, but it would be convenient to let the device download those.
Any info on that would be welcome, I couldn't find anything on the web.
I was able to narrow the problem down to the .314 update. Does anyone get updates via Sony Update Center on the phone on .314 FW? If yes, what branding are you using?
sony update center is no longer supported and generaly problematic
it seems to often just think a device has modified content for me
though it seems to be fine with old devices

You mean SEUS, right? I know that the desktop program has been discontinued.
I meant the apk...
It's funny, because if I install 402 without wiping data and using custom kernel it does detect all the updates. Even with unlocked bootloader. Just after installing 314 the update center stops working and shows nothing. I even tried with the old build.prop from 402, still no updates shown 0.o
I downgraded the apk from 2.2.1.A.0.8 (stock 314) to 2.2.1.A.0.4 (stock 402) and still no go. Wrrrr, I'm out of ideas.

it will not work with an unlocked bootloader (tried many times wirh Z2 and xperia s)
it shouldent work after 314 firmware, i think 314 for Z2 should be last to be uploaded to the server before all are limited th SPCC
sony are trying to force people to use Sony Pc companion
you can use flashtool to upgrade, just dont wipe your data when you update

Does anyone have the "updatecenter.apk" on FW .402 ?
My update center works fine on 314 and downloads as well as installs updated sony apps.
Mime hasn't updated any apps since switching to. 314. I had no problems before then. Hope this gets figured out soon.

Flashing Z5 Compact prototype - flashing via Sony Mobile Flasher question

Hi everybody,
I got my hands on a Z5 Compact Prototype (really cool, it has xx MP written on the back and a few other quirks), otherwise it's a completely normal phone. The model is still E5823, customization 1298-7258 R5B and current software 32.0.A.4.11 (5.0.1).
I'm wondering, is it possible to flash the latest Nougat or at least a MM stock ROM using the Sony Mobile Flasher? I'm asking because I'm afraid I might brick it (I never flashed a ROM in the Mobile Flasher beforehand). The drivers look OK, it is detected as an ADB device.
Also, is there any way to backup the current ROM and to revert to it later if needed? I tried the Xperia Companion/Repair my Sony but I don't think it works on this new version.
Thanks in advance.

Are you rooted? If you are you can try and take the build.prop from a retail unit firmware and replace yours with it. This way you will avoid hard bricking it. Also, take note of the firmware you are running and download Xperifirm (there you can check which exactly it is and download new firmwares directly). Xperia Companion might not work because 1) you are running a pre-release ROM and 2) differences in actual unit. *IF* it's the second one, I'd be very careful (tho with Flashtool you should be fine, Sony phones are hard to hard brick).
EDIT: You can compare the build.prop files and use common sense to find out whether it will be of any use to actually replace it..

Thanks for the tips.
I managed to flash a stock E5823 32.2.A.0.305 firmware (6.0.1) and it works perfectly. It's just that it detects an OTA Update for the 32.2.A.5.11 but it cannot install it; looks like flashing with Flashtool is the only option. I guess I'll wait for a stable 7.0 and I'll flash it afterwards.

This is excellent news! Since it's a prototype the FOTA partitions might not have been set up or don't work properly (if you have a saved Flashtool log you might be able to see which it is, although they should be fine since flashing hasn't failed ) but that's ok since you can use Flashtool. Are you going to root it? Also, Nougat is out, so be sure to root before you update :fingers-crossed: :fingers-crossed:
I've already flashed the latest (.378) Nougat build and it works great, just like before.
I know that there were some problems with root on Nougat. I don't really need root access because I don't use the device as a daily driver, but if I'd like to get root access I need to revert to MM via Flashtool? Can I still do that now?
PS: You can see a review of it with MM installed right here: https://forum.xda-developers.com/z5-compact/general/short-review-sony-z5-compact-prototype-t3555140

That's awesome! I also unwittingly bought a prototype and wanted to flash it to Nougat, but am worried about bricking it. How did you go about flashing it?
oh my god this is the tread i found, i have XZ premium prototype one looking for the way to flash original firmware. i found XZ premium firmware from Xpirifirm already downloaded and create ftf(as it really new one so i see no device number to pick i rather pick XZ name on it anyhow it is create with no issue).
but the problem is i go to flash it and flash tools newest version ask me to enter flash mode. i did but it did not go i do not know why, anyone knows why it cant be flash? do i need to install any drivers? or anything else to flash it? or it just need to wait for flashtools to update support for my device first? thanks in advance

No, it won`t get OTA if you flash f/w from non native region, even if you flas f/w from BC72 to BC72.

Global C2 is HK, you are right. It comes with all Google services and apps installed from the box, and if you get OTA it is your native f/w.
Chinese (NOT HK or TW!) XQ-BC72 devices comes without Google apps from the box, however, it does has Google services inside the f/w, and you can install Google apps (market, gmail, youtube e.t.c) manually with no problem, so it won`t be almost any difference between HK and Chinese rom after you install the apps manually by yourself.

Yes, you can flash updated f/w with Newflasher from any XQ-BC72 to any QX-BC72 with no problem, but you must remember the main thing - OTA update system stops working on non native f/w!

Thank you very much for your reply. I agree with you that it does not make sense to flash Chinese f/w to HK f/w. It just that I do not like the look of Google apks and the Google calendar does not have a year view. You are right, losing OTA update is a problem. I will just disable the Google apks and chose some other equivalent apks.

I've got you. Yes, you can try to flash CN f/w on your HK device, but it doesn't make any sense. CN f/w is poor, it doesn't have any google apps pre-installed, however, it does have a google services, you just need to install g apps manually by yourself.
Try SEA f/w instead od CN
I just like to try f/w with different apps instead of g apps. If the SEA f/w is similar to HK f/w with g apps then I am not so interest in it unless it has some features different than the HK f/w.

My device is HK BC72 out of the box (I think) since the software info says GLOBAL-C2-user. I am afraid that if I flash a previous software version I might get boot loop due to anti roll back. I just had a hard brick on my Mi 11 due to flashing an android 12 version. I do not want to brick my new xperia so soon. I should be able to fix the boot loop using Xperia companion right?

I would have done that if the CN version is also 61.0.A.14.3. I do not want to brick the phone due to anti roll back.

Not everyone bootloop can be fix by XC recovering. If you will flash the device without changing slot, you won't be able to repair the device with XC, for example.
There's no anti roll back protection on Xperias, as i know. You may flash the older f/w back with no problem, just chande to slot A as active before flashing.

I flashed back my device from newer RU f/w to older CN f/w, and it flashed great. After that i made a companion repair, and now i'm using it.
