try flash clean firmware

I am facing same issue with my Xperia z2, Any solutions?

Download latest Lolipop ftf for ur device model and flash it Via flashtool. Do a clean flash.. If problem exist try any kitkat ftf. Again problem happen means sent ur device to service center

Try a repair with PC companion if you have a original firmware here. Or you try a clean flash(with wipe data) of last firmware with flashtool.

[Q] Touchscreen failure after stock update

Hey guys,
i have a very very big problem.
The X10i of my girlfriend restarts randomly the last weeks, so i decided to flash the new firmware using "Sony Ericsson PC Companion" (Germany).
So far no problems, i connected and updated the firmware, SEUS said "done, please disconnect and restart" and now the touchscreen is functionally only for about 5 - 10 seconds.
After this i can't press anything except the hard keys.
If I do nothing, the phone restarts.
I've already done the firmware update twice but no difference.
Can anybode help me?!
Thanks
-----------------
edit2:
Problem still there.
Sometimes I can use the touchscreen for a short period of time, but after a while there ist still the problem from the beginning.
-----------------
edit:
I've just used the Flash Tool to downgrade and upgrade the kernel.
Now it seems that there are no problems anymore.
I hope so.
goto http://forum.xda-developers.com/showthread.php?t=920746 and flah a 2.1 ftf file into the x10 and it should fix it.
If still not working send it to Sony Ericsson for a repair and make stutter you unroot your phone beforehand.

Flashing/Installing Miui 1.9.16 language pack
Thank you guys,
after rebooting the phone several times there isn't any problem with the touchscreen anymore.
I don't know what the problem was and if it will get back.
Maybe I will try your suggestion x10 2.2 user.
Now I have another question:
I've flashed a miui 1.9.16 rom and it's working like a charm.
But I can't using the language pack by saandur to change the rom language to german (my girlfriend isn't very familiar to the english language), I've tried all possible combinations of wiping the cache partition and dalvik cache before and after flashing.
My process was:
Stock 2.3.3. Android rom
-> used Flashtool to get root access
-> used Flashtool to install xRecovery
-> installed miui 1.9.16 rom using xRecovery
-> rebooted
-> wiped dalvik cache
-> flashed language pack
-> reboot
But in the settings I can only choose between english and chinese.
Any suggestions?

[Q] Bluetooth Problem in Xperia Neo L

Hello Freinds,
I have the major issue of bluetooth with my neo L.
Problem occured when I try to turn bluetooth ON, It force the device to restart and enters in bootloop.
I have stock rom and stock kernel and not-rooted.
Xperia Support suggest me to do factory reset the device.
I did factory reset and it works well after reset.
But after 2 weeks, the same problem happened again.
So, My point is that I have to reset it again and I have to configure my phone as per my use again and again..
It is very irritating.
Please give me any other option to solve the problem or fix it because i dont want to reset my phone, and it took 2-3 days to reconfigure my phone.
Please give me another solution as soon as possible,
Thanks,
Raaj

Hello Androidians,
All of you know about the "bluetooth bootloop" of Android ICS rom.
After using somedays, phone restarts on Boot Screen if you try to turn on Bluetooth.
After searching a lot and testing so many mathods, I've found an working one
Just boot in recovery mod and wipe delvik cache.
This will solve ur problem for sure.
Tested in Sony Xperia 2011 phones and and Neo L too.
If you persist the problem of bluetooth not getting turn ON, follow below procedure.
There is a app named "Bluetooth Fix Repair" on playstore.
Download & install the app from playstore
GooglePlay: Bluetooth Fix Repair
Run the app.
Tap on screen to FiX Bluetooth. thats simple.
now bootloop problem is solved. restart your device. turn on Bluetooth to check.
TADA....
Please Hit Thanks if you solve your problem.

Z2 (D6503) can't make phone calls after restart

Hello,
So yesterday I just solved my own issue of not getting any LTE signals by reinstalling the FW.
Today, I followed the advice of a user to restart the phone using PWR + VOL UP buttons to get the smoothness back. I did just that, phone became smooth again with the phone registering on LTE network.
But what happens now? I can't connect to Mobile Data AND can't make phone calls. I can run USSD code to check my balance and can receive calls just fine but cannot make phone calls.
Any ideas? Do I need to reinstall the FW again?
Model: D6503 FW: .314
Try flashing the baseband for your firmware and see if the problem persists.

I actually tried repairing it via Sony PC Companion application on the PC but to no effect. I'm suspecting it could be a HW issue but what baffles me is that it used to work fine (apart from the LTE issue) and only after I tried repairing it yesterday did everything work correctly and wham in the morning this happened.
try to flash the latest FTF again using flash tool..and check if it can help

problem with firm ware version 17.1.2.A.0.314

So some time back I made a thread regarding a problem I was facing. My phone would randomly freeze up and restart on its own. I tried hard resettig, repairing using PC companion, flashing using Flashtools , changing SIMs etc. but nothing seemed to fix it. Then I had to arrive to the dreadful conclusion that it was a hardware fault. But 2 days ago I got the bright idea of flashing an older firm ware version (17.1.1.A.0.438) using flash tools without wiping internal data and now the problem is 100% fixed. the phone hasn't restarted even once after a 3 full days of heavy use. So with this I can safely say that the probem is with the 17.1.2.A.0.314 firmware. Has anyone else had this issue? because my friend also owns a z2 and his phone works just fine with the 17.1.2.A.0.314 firmware. Any ideas how to fix it?
