By any chance did you try to unlock the bootloader and lost TA partition and DRM keys? If yes , try to relock bootloader then flash ftf

ee, I never did that, but thanks anyway.
How did you try reinstalling? Use a .ftf with Androxyde's Flashtool, provided you're able to boot into flashmode (if you can't, sorry bro, you're screwed). Flash everything, but uncheck DATA in the Wipe section if you want to keep your files - you'll lose them otherwise (your apps are gone anyway). This should work, as I've bugged, bricked, and bootlooped my phone more times than I can count, and this has always worked. If it doesn't, then I don't think anything can help you.
Good luck.

Unfortunely, nothing helps. Flashtool doesn't, SUS also nothing, I sent my phone to the servis.

[HELP] :( Xperia Z C6602 won't turn on - Flashes 3 times a red light

Help, First time flashing a ROM on a Sony phone. I have experience flashing, unlocking bootloaders and rooting, etc... but I normally do this on my Samsung phones.
So... This is what happened. I recently tried to change my Sister's Xperia Z (C6602) ROM so I could try if I could get 4k video out of its incredible camera. But I didn't have any knowledge on how it is done on a Sony phone. I researched on various sites how it is done.
First I saw NUT's dual Recovery and I downloaded it so I could get Recovery on the phone. I downloaded it and I tried using the third option which includes rooting. But I couldn't get it to work. It seemed like it couldn't root the phone properly. So I tried using vRoot (failed), tried an utility that I found while researching and I got it to root. Went back to NUT's dual recovery, installed Recovery, everything wen't excellent to this point. Sister didn't made backup so I couldn't flash the ROM yet.
Researched how to Unlock the Bootloader, saw that Sony let developers unlock the bootloader and I did it using fastboot and the code from Sony, the wrong part is that I didn't backup the TA Partition (Had TA Backup utility XDA site open on chrome but didn't use it since I thought nothing would go wrong if I didn't make a backup of the TA partition) and yes I lost the DRM keys... After this I found out that loosing DRM keys means no Bravia Engine, Music ID, etc... (I hate you SONY )
After loosing DRM keys, I was worried that my sister would kill me, so I searched trough XDA and found that you could get some functionality back from recovering the TA partition and flashing a zip from jimRnor but I needed to flash 10.5.A.0.230 ftf using flashtool. So I did it. relocked bootloader, flashed 10.5.A.0.230, booted to 10.5.A.0.230, turned off the phone, unlocked bootloader using flashtool, used recovery to flash the zip, and done.
So this is the part where I made the phone not work... (And I deleted some of my sister's photos because unlocked bootloader without backing up woopsies)
Sorry for the long story...
Wen't to recovery, tried to flash iHackers v5.2 but somehow the file didn't downloaded correctly, got some errors during installation and I turned off the phone to go check what happened that I couldn't get the zip to flash. And by turning off the phone. It somehow got corrupted or something and now the phone won't turn back on. It stayed with the LED on red. I found it strange so I pressed Power + VolUp for like 5 seconds and it turned off, and then I tried turning it on again and nothing happened. Tried different combinations and nothing would happen. lastly I tried using Power + VolUp + VolDown for 20 seconds and now it is flashing 3 times a red light on the LED. and this is how it has been for a while.
So please, has anyone had any experience with this type of problem, what should I do and what I need to learn for the next time.
P.D. Yes, I didn't know that Flashtool could do everything from rooting, backing up TA partition, unlocking/locking bootloader. I found out after I had some time using the utility.
P.D. I can't get access to neither flash mode or fastboot mode, PC won't recognize the phone.

[Q] Xperia ZQ Reboot Loop - Last hope :(

Greetings, everyone.
I have an Xperia ZQ (C6503) which suddenly started rebooting itself continuously about 5 seconds after it enters the system (after the SONY or Xperia logo). First I tried removing several apps, deactivating functionalities on the short time available after each reboot.
I tried, then, flashing the STOCK Android 4.4.2 and 4.4.4. Nothing.
Did the process using PC Companion, it updated but still nothing.
Unlocked the phone (don't even know why I did that, guess I was desperate and thought this could help).
Tried flashing a custom ROM. Same thing.
As the mobile is warranty void (I bought it 2 years ago) my question is: is there still something I can do (something that they would try on the customer service, for instance) that can be attemped or my only option is to dispose of this cursed device? :/

Firstly, you've made a major mistake - you didn't take TA partition backup, as a result you've lost your DRM keys forever.
Secondly, have you checked all the boxes for WIPE'ing? (Data/system/caches)
You tried to flash custom rom through recovery or using fastboot?

Hi, thanks for the reply.
None of the tutorials I followed mentioned anything about this TA partition. What is this and what are the DRM let's? All the boxes were always checked for wiping on classrooms and I flashed the custom ROM via fastboot.

DRM keys is like a signature of the phone license. Without DRM keys your camera won't take good phones with drm keys, clear audio and bravia engine stops working either. Pushing any other phone's ta-partition backup will lead your phone to hard-brick.
Anyway, give a try to flash generic .ftf, or via phone recovery

Although it wouldn't recover the DRM keys, wouldn't this solve the issue you mentioned?
http://forum.xda-developers.com/crossdevice-dev/sony/xperia-z1-z2-z3-series-devices-drm-t2930672
I flashed several generic and specific .ftf and all of them presented the exact same result (the system didn't load correctly and the reboot loop continued). When you say via phone recovery you mean the PC Companion method? I did that, too and - once again - the result was exactly the same :/

Yeah, excatly only this way could restore all the DRM features.
About not working, I don't have any other ideas, sorry for that :/
Use Emma to flash it. (Emma is a PC software) When you have started the application connect your phone to your pc while it is turned off and while you are holding the volume down button.
You could have a corrupted partition('s) which may prevent flashtool writing the images. Possible solution is to fastboot a custom kernel and format EVERYTHING you can in recovery.
Then try to flash a stock ftf again. Good luck:thumbup:
If you have an external micro sd card in your device take it out and then reboot your device without the sd card. Worked for me.(on xperia z c6603) The sd card caused the bootloop. Why it caused the bootloop i still don't know.
And if that does not work, wipe your dalvik cache in recovery
need help
greetings
may u help me with that?

Backup and Restore function is gone

So i tried to rebrand my chinese huawei honor 9 lite to an european version, i was close to finishing it, then i made a mistake and reset my phone. After my phone opened again all the apps were different color, for example the calculator was orange before i reseted after reset it turned to grey. Also the settings app before was in homescreen now i need to drag down from top of the screen to open settings and worst of all when i click the back up and restore button in settings its blank i can factory reset but it doesnt reset back to the the start where i select language it resets back to the phone homescreen where i swip to unlock and also before reset there was hi apps or app gallery after reset no app gallery. Before reset bootloader was unlocked after reset for some reason it says its locked again. I tried to enter e recovery but when i do factory data reset it doesn't reset to the choose a language section it resets back to homescreen. Also when i go to about phone before the phones name was honor 9 lite now its huawei phone also before the model was LLD-AL00 after the reset it says the model was Unknown
@Imfriendly
Hello,
i think, you need from your build (before rebrand) a FULL-Update to rebrand to delivered state.
if then your phone in delivered state you need from your "wish-build" a FULL-Update.
but - i never phones rebrand. i reed in other threads that first action is flash partition "oeminfo" and then install FULL-Update
i hope this help and work for you
if you only rebrand for google - you not must rebrand : install google-installer https://mega.nz/#!Vlk3TRhR!8lop5P9Nap9QQEc2O0pZwRrlSBYm4o-f7k_4CnRBaJ0
before you anything do - think on backup from your data
I see i just tried to follow a step to step guide yet still messed it up but is there a way for me to reset the phone back to when i first got it cause right now when i do factory reset it doesn't do that and backup and restore function is blank when i click on it in security
