[Q] Phone doesn't do anything, only backlight is on - Xperia SP Q&A, Help & Troubleshooting

Hi. My friend has an SP, it's stock and unrooted, and a few weeks ago the phone started to hang on black screen with backlight on. Of course he tried to reset the phone with the button under the battery, with no success. He returned it to the store, they only reflashed the stock rom, it worked for a day now it's the same. Has anybody find any solution to this? I tried to search for exact similar problems, but I couldn't find any with proper answers. I think he is on 4.3. Thanks for any help!

yes.. flash stock 4.1.2 ftf with flash tool.. if that not solve your problem then 99% is hardware issue..
btw i tell you to flash 4.1.2 and not 4.3 cause 4.3 is full of bugs..
You can follow this guide http://forum.xda-developers.com/showthread.php?t=2658952 to do this... but i prefer u to install 4.1.2 (12.0.A.1.257 or 12.0.A.2.254).. if you install 12.0.A.1.257 then update to 12.0.A.2.254 with your phone not with sus.. cause with sus it will go to buggy 4.3 (12.1.A.0.266).. for 4.3 this week i think sony will release new bugfixing version

Mine is doing the same, also battery drains.
I think it's about JB basebands, i've tried a lot of versions.
It's doing like this when phone is using one band but i don't know which one, i think 3G on 900Mhz because this type of freq. is used outside towns.

It's weird, if you're running .489 JB version then you could try flashing .492 JB version from following thread and see if it could help.

Try Repair My Phone with Sony Update Service,

I wouldn't flash to foreign firmware.

Why is there any risk associated with that
It's absolutely safe flashing foreign FW.
The OP already stated that he flashed stock FW, so repairing won't help much I guess.

Reflash a stock ROM with the flashtool, which you should have found out how to do before flashing anything. Read the stickys for links.
From me to you.

I want to get rid of the problem so i keep on checking it.
Is this problem related to Kernel or some chip problem?
If this is kernel related Plz suggest me kernel(not stock) and custom ROM (4.2.2) for my device.
I will revert back if or not i get my solution.
Your problem is the kernel.
Stock rom is the most stable.

Glad That I am not alone....
I have tried everything possible on the software part i.e installing roms and kernels....but no result
I think this might be problem from hardware side(Battery, its connectors etc)
When does your problem started?
and have you tried to replace battery?

As i wrote i sent it to a support company thats is certified by SONY.
My problem is there for three or four days.
I did not try to open the backcover becaus of warranty.
I hope that the company repairs my phone quickly and i can report what was the problem at the hardware.

Upgrade/downgrade...

Hi,
I am thinking of flashing the 4.4 upgrade to my z1 to see if the Bluetooth issues that I had on 4.3 will be resolved. My question is -
If I upgrade to 4.4 and I am still having Bluetooth issues, will I have any problems downgrading back to 4.4.2?
Any help will be appreciated!
P.S. I don't need to have root access!
Yes because you cannot downgrade from 4.4 to 4.4.2, they are the same
If you mean downgrading to 4.2 or 4.3, it should be fine (AFAIK)
Remember there was the loss of IMEI going from 4.3 to 4.2, so I suggest only downgrading to 4.3

Hi gregbradley
Thank you for your reply,,,
Sorry I meant downgrade from 4.4.2 to 4.2.2...
I have tried the upgrade to both .290 and .136 (4.3) and back again to .257 (4.2.2) and did not suffer any IMEI loss.. Does this mean that I was just lucky or?

[Q] Camera issue

[
I have a xperia Z1. Initially i unlocked bootloader because that time I thought it was the only way to root it.
I flashed the 4.2 and rooted...boom camera didn't work. Seems it's the autofocus that jams the app.
then upgraded to Jelly bean and the camera started to work again. Perfectly.
I recently upgraded to kit kat and now the camera is back to not working again.
I tried to restore the individual camera app but it didn't work
I can't find any others who has the same issue about kit kat and I find that odd,
Any suggestions?

I suggest you get the FTF for the region, customisation and FW you are on now and flash it using PCCompanion. Find them in the mega collection thread.
If there is not one then you can make one by following the guide in the OP of the mega collection thread

I flashed back to stock using this
C6903_14.1.G.1.534_Generic DK 1276-1249-R5A.ftf
and then I upgraded through sony companion
Voila! As simple as that.
Now I dont have root.
The weird thing about the bootloader is... I had it unlocked. Then I relocked it using flashtool, cause I thought it might fix the camera...Now I cant unlock it again using flashtool. I hit the BLUE button. I reboot in fastboot and I get that window with the Imei and unlock code.
I then hit the unlock button but nothing happens. The program doesnt react at all.
