its not good
i recommend to ask for replacement if it has warranty
If not Download PC Companion app connect ur phone and click to check for update if there is no update then select repair firmware option
after this if problem remains u should take to service cause it can be hardware issue
:good:

My phone also keeps restarting can't get into recovery. . .

Try a repair update using SE update service or use flashtool.

Have you tried wotanserver.com
Otherwise, my guess is it might be a hardware issue, not a software one (because flashtool/update service/wotan server return your phone to stock. meaning if something was f*ed up, it should be fixed...)
Just use the Sues tool (aka. sony's flashing tool) and have it flash the latest update. If that doesn't work just tell your carrier that it did this after you installed and OTA update and maybe they'll give you a new one.
Yes!
Last Evening I tried the SE update service . right away it didnt work , so i posted , that my phone is still bricked. Today at school about 12 hours after i used the SE update service and the phone was "dead" it FINALLY booted to the os! Yay! im no longer bricked!
Thanks For the help! I appreciate it!
Not Again!
So........ the issue has continiued , after two weeks of perfect performance.
well....i guess the screen is to blame here , because when i touch it in places , that i know a button exists i can feel the vibration!
Ive been playing paintball and running around with the phone in my pocket , so i guess ill have to start saving money for a screen repair
So root wasn't here to blame.

[Q] Won't boot...settings got changed!!

Won't boot...settings got changed!!
HELP!! Sony xperia M 4.3 android won't boot up...?
Go easy one me cause I'm a first timer...
Not rooted...
Earlier today I was messing with my phone went: SETTINGS-SECURITY-APP OPS went across to DEVICE pane and changed all the options in the part for ANDROID SYSTEM from Allow to Ask Every Time...after that the phone just stopped working and froze. I took out the battery and put it back in thinking everything would be alright...however when I turned it back on the phone only got to the network welcome screen and stopped...I think what I did was the problem...what can I do to rectify the problem....HELP! Nothing works!
Bro if it isn't rooted than connect your xperia to your pc through pc companion software and repair it,and it will be good as new.
Hit thanks

Problem with SIM card...

Hello guys... I'm new here... but I've already follow lots of your instructions to help me out
The problem is... I have a Xperia ZL that is 1 yo... actually, it's 1 year and 1 month old... (yep, here in Brazil Sony delayed to release thei products, now it's a little bit faster, we already have Z3 in stores )...
The phone was rooted with towelroot and working just fine... suddenly it didn't recognize my SIM Card no more... then it just started to act strangely... the band signal was blank and there was a red X on it... then the phone stopped responding at all and started a infinite loop of restarts... just bought a new blank SIM and transfered my number to it... NOTHING HAPPENED.... I started search into the net, the forum... some attempts and nothing... so I use the Sony PC Companion to repair my phone... nothing new... then I use flashtool and the newest firmware "C6503 10.5.1.A.0.292" for it.. the phone started to work again...
I was using it for 2 days and suddenly (again) the same symptoms happened... no signal at all... then ... no phone at all... it starts... the a black screen with the "back" button and the "no signal", battery and time... when I try to pull down the bar it's RUSSIAN! (and I got the brazilian firmware)... then the phone restart... SONY..XPERIA... same things... nothing new...
I've tried to repair with PC Companion... flashed and REFLASHED with the firmware... and NOTHING... I thought it could be the SIM... but it's working on other phones....
Guys, DUNNO what to do... but I'm desperate!!!
HELP ME PLEASE!!!!!

Frnd, install Catlog-Lofcat Reader application from playstore and let it monitor your phone in the background for sometime. See if there is any 'error' in processes related to your problem. Error is indicated by red colour square box with 'E' inside it

My suggestion,
Steps
1) If your bootloader is unlocked, relock your bootloader
2) Now goto flashmode, use flashtool to install your firmware which previously worked fine for you.
From your previous post, i could understand that after a fresh firmware update it was working fine for 2 days before the same problem started to appear.
3) Once the OS loads and home screen appears, goto playstore and download catlog and let it monitor until the problem occurs again.
We will see from your log.....
I suspect this could be a software issue. Try using any older firmware....

Hello.. yep.. it had worked for 2 days then stopped again...

In flashmode I've done that and it's not working... same result everytime I do that...

What are the ftf files that you tried flashing using flashtools.give me the full version nos
You mean to say, after flashing your ftf file via flashtool this time it is going to bootloop
and it's not working for 2 days like it did before.
As previously said try download and flashing any old firmware(preferably jellybean) ftf files which has got good reviews that it worked.See if goes into bootloop without booting into homescreen
Don't worry if you have not done anything to unlock bootloader it will still be locked. Don't mess up with bootloader if you are not sure about what you are doing.
If it is unlocked it will ask to relock when you use BLU button in flashtool

What's the "full version nos" I mean, where can I see that?
I'll try to grab an old version to see if it works... didn't try that.. only with newer versions...
I said that the when the problem appeared for the 1st time I flashed the phone and it worked for 2 days... then started looping again... but now I can't make it work anymore.. doing flash doens't change the loopings... I'll try an old version..
"bout the bootloader, I didn't change anything... I mean, not that I know... LOL... HOW we do that? (so I can confirm I didn't do anything)... This "BLU button" I think I tried that once... how to know if it's locked or unlocked now? LOL
THANKS for your help!!

K once you install a older ftf firmware file, reply me back with the results.(Preferably any jellybean version Example-10.4.1.b.0.101(Be sure to download your country variant)). If you are able to goto flashmode, i am sure that you can revive your phone. What i meant by full version no is nothing but 10.5.A.0.230 or 10.5.1.A.0.283 etc. I guess your ftf file is not proper thats why you are going into a bootloop. Like i said download any old firmware file and flash it.
If you had already unlocked your bootloader using BLU button in flashtool, now when you click BLU button it will give you and option to 'relock' instead of 'unlock'. If it shows 'relock' it means your bootloader is unlocked.
See my replies in the below thread to understand more about what could cause bootloop problems....

Sorry to hear that frnd. Seems something is really messed up in your phone.
I guess since you tried flashing different firmwares it might be a hardware problem causing this issue. But to be sure about which part (SIM related issue, could even be issue related to TA partition ) caused the reboot issue, i need to see the logs which will be easy for you to collect if your device boots properly,which is not possible for your case .
There is another way to collect it but you should have already enabled 'USB Debugging mode' in your mobile the last time it worked. Anyway try and select if it works. Check below link to see how to access logs. Even if we get logs if it is hardware related issue you still need to get it to sony service center.
http://developer.android.com/tools/help/logcat.html
It is upto you. I could still further down on this issue but it is upto you. I suggest you, take your mobile to service center if they cannot do anything/if they say you should use it as a costly paperweight, get it here we will go on with advanced tracking methods/we will even try unlocking your bootloader and try flashing custom rom to see if it works. . But beware, i am NOT responsible for any further damage if it happens to your mobile...
If you further want to take the risk Private message me i will give you my skype id.

[Q] Xperia ZL Loops on Sony Logo (Tried Everything)

Hello everyone
I have been a silent follower of xda from past 4 to 5 years and never had to ask for help
as I could figure out my way through when i get stuck untill now
My Xperia ZL loops on Sony Logo
My phone does enter FLASHMODE and FASTBOOT mode and im able to flash ftf Firmware without any errors in flashtool
but when it asks to unplug and restart my phone i get the same loops
I have tried yellow button Soft reset (stays in a loop after reboot)
i have tried yellow button Hard reset (Powers off after 3 vibrations)
I gave it to sony service here in India(Hyderabad) they are suggesting me to replace the motherboard which costs 24,000 INR/-(Seriously?)
i bought the phone 2 years back for 29,000 INR/- and now they want me to pay 75% of the price I strongly believe they follow their blind
rules of pushing the customer to go for motherboard replacement if they are not able to revive the phone after basic software flashing
but i still believe i can recover my phone if all the gurus out here can help me out
The phone still didnt go dead till now(some battery left may be still looping) ill try once again if the battery dies completely
EDIT:1
Tried flashing New 5.02 lollipop ftf, after successful flashing with no errors
unplugged it and tried to turn it on
Now red LED flashes 3 times but the device doesnt start
connected it to a wall charger and now i can see the kernel charging screen with battery symbol showing the charging
after some 7% charging indicated i tried to start the phone and the same inevitable loops with sony logo come back
Just plug it in and let it charge for a couple of hours, if it still bootloops, try Sony's Flashtool EMMA. I know people say it's ****, but it fixed my phone when I was in the same position as you.

Edit: Tried using emma tool but it says No services available for your device

there is C6503 but no C6502
i see you can fastboot your devices.. Why not trying the Cyanogenmod for a moment?

Have you even tried to flash any .img file containing TRWP using flashtool? plus, when connecting the USB cable, use the white button under the cover to turn it off, then on, instead of the normal power button. After these steps, flash a NEW .ZIP rom Usin TRWP

sony service centre ! They never do repair on z series.If it's in warranty drop it on service centre .they will give you a refurbished phone.
IF warranty is over you can ask them .But i m 100% sure they don't do repair as many other countries.Depends where you live.
you can do it on your own @ your own risk.Remember battery is slightly glued underneath the screen.
Always remember to order battery with that cables and connection.
Sorry for long reply .But in this kind of matters we are frustrated & you don't want to waste money & our phones.
use button
use the tiny button beside sdcard press that untill 3 times vibrate and hold button vol down in flasmood mode
Try boot with USB cable connected to 1.5A+ charger with good cable.
No Hope guys tried everything im pretty sure its battery problem but the service center guys dont want to listen to me at all
all they want me to do is get it replaced for a new phone for 24,000 INR (360$) are you kidding me? for a Xperia ZL
Im even ready to give away the phone if someone wants to help me out
I have the same problem with my ZL. Service center refused to replace the battery, so I asked someone else to do it. That however didn't fix the problem. When I push at the back between the flashlight and XPERIA the phone will switch off. When I disconnect the battery and connect it again it will start-up again. I removed the screw below the camera module, as fastening that one also made the phone turn off. There is something wrong with the motherboard. I always had my phone in a flip case and it didn't even have a single scratch on it. First time it went of was while making a video. Possibly overheating caused this problem or damaged a circuit at the motherboard. Very disappointed, phone was just 2 month out of warranty, first time off was within but that doesn't count.

I always had my phone in a flip case and it didn't even have a single scratch on it. First time it went of was while making a video. Possibly overheating caused this problem or damaged a circuit at the motherboard. Very disappointed, phone was just 2 month out of warranty, first time off was within but that doesn't count.

I was in the same boat as you with my refurbished ZL. Flashed anything, doesn't boot. Then battery full drained and only red light. Service told me it's motherboard circuit. I didn't lesten them, bought cheap battery and replaced it by myself: and Xperia worked like a charm but only 3 months ))) New (cheap) battery got trouble on GPS route suddenly. And phone worked only with power cord connected, shutdown without. New battery will again fix it )

HELP needed! G4 Bootloop!!

Hello guys!
It all started today in the morning when I opened Instagram application on my G4 (H815 model) and suddenly the phone froze. After 15 or 20 seconds it tried to reboot itself but it went straight into bootloop. It's not acctually a bootloop. It tries to go past loading screen and reboots another time and after that all I can see is LG logo.
I tried to enter recovery mode. No success. I tried updating/flashing KDZ file with LG Flash Tool and I got error everytime saying there was not enough information....
Last thing I tried was to boot into download mode. It shows Firmware Update screen but I don't thing ADB is working. I tried command adb devices and it found nothing.
I'm so desperate now as I need phone tomorrow. I hope it's not hard-bricked. Do any of you have idea what to do?
Any help apprechiated
TIA

are you sure it's dead???
Cause, OMG!
I can't be without phone. Is there any other way?
And BTW, I have unlocked bootloader, so no warranty for me
Why do I need first 3 digits of serial number?

lots of people report bottloops theres a thread and i said about 80% suffers from it.. its a hardware problem from lg .
thers the flash kdz to disable big core ,phone will be slow but usable.. and some have reported that warranty was denied and some had luck and phone was fixed give it a try..
because the first phone are suppose to be more likely to suffer from it.. so to know if its old earlier phone. or new one . that soeant suppose to happen anymore but it still does..

Thanks for the info. I checked serial number on the box and it says 507. I know a lot of 505 has this issue.
Do you have a link to that thread to disable main cores? I can still sell working phone rather than bricked
And I'm so pissed now because I didn't do anything wrong. Damn LG! Life's not good anymore!!
Is there possibility to flash KDZ with other program than LG flash tool? I can't get it working, it always says it couldn't find right information...

I want to fix it. This would probably be possible if LG flash tool worked. Do you have any suggestions? I really like this phone

well, i guess I'll have to buy new phone. I'm a little disappointed with LG for this issue. Anyway, thanks for all of the useful posts. Thread can be locked now
Yes it's LG issue, but if you had not unlocked the bootloader , you would still have warranty. They will be fix this without problem

well only time will tell most will do .its just a matter of time.. since they are new and the ones getting bootloops are older.. so they say it takes about 8-9 months to show.. will need to wait and see. in 10 months from manufacturing date.
you cant tell wich one will but, LG says they fixed the issue in new phones..

Yes, I tried everything. I've sent LG G4 for repair with unlocked bootloader, they replaced it without problems. I was without phone for 16 days though. It's working now, but I have some WiFi issues (slow download speeds)
