[SOLVED] Sudden Reboots on my Xperia T - Sony Xperia T, TL, TX, V

Hey guys,
I have a problem on my xperia T and it really pisses me off, can someone tell me the common causes of sudden reboots on xperia T.
I have once rooted and bootloader locked, but right now i went fastboot and tried the new 4.3 so my device went unrooted. I thought this was
a minor bug and would be gone once i go 4.3, but it still haunts me..
any suggestions? solutions to this problem would be nice too :fingers-crossed:
P.S.
it always occur when i have active data connection (wifi,mobile data) and also when my battery drops below 60%

I have the same problem.It related to the sim.Just remove the sim card and see whether the problem happen

Do u use underclocking or undervolting?
You may need to do a full wipe due to solve problems

reinstall the rom,and see if the bug still exist,if yes try to go back to stock rom using pcc,or update service.If the bug is still on stock that may be a hardware problem i think.
My phone was doing this when I was using alfs kernel. If you are using alfs try to move to nAa kernel. Since I use that no such problem occurs.

Xperia z wifi failing

My wifi stopped working since 2 weeks ago after a abnormal crash. Every time when I try to turn on wifi, it keeps saying turning on, but never did. Which causes the Stamina mode not working anymore.(and I think the phone keeps attempting to turn on wifi also increases battery usage) The Bluetooth also stopped working since then. I did factory reset number of times and Repair with PC companion, still not a chance.
Finally, I found a temp. solution, which I completely drain the battery and charge it from 0% to 100% with phone off. It seems this could reset the wifi problem. But once I connect back to my home wifi, it would cause an abnormal freeze(notification led become RED) and then reboot automatically, and then wifi stop working again. I searched a few posts and some people with xperia S had a similar wifi problem, but no solution.
I got a feeling that something crashes the wifi driver, and this cannot be reset either factory reset or SUS repair. Is there anyone here got a similar problem like me? Or anyone could explain what actually happening to my phone?
Thx

Did you had any luck with your WiFi? I have exactly the same problem,it keeps turning on without able see any network and the battery discharge faster.This happened to me after installing the app of dsploit,Tried to re-install the rom and re-lock the bootloader but still the same.
You better send to service center for repairing than fix it your self,very waste time and your money.if like to fix yourself better go to buy ap set not original.thing wisely,Man!!

Do you know how much money i will pay? because i have unlocked the bootloader and i think it voids the warranty because i did that but i will relock it when i'll give it to the service center.
i had same trouble then, but when i restore my backup its working great again! :laugh:

[Q] Has anyone with an Xperia TX faced the Sleep of Death (SoD) problem?

Hi,
I bought an Xperia TX about three weeks ago. Since then the phone has gone into the sleep of death state four times! I've read all the discussions regarding the same problem in other phones such as Xperia T, V and Z, and applied suggested fixes such as turning the WiFi off when not using the phone. But, alas, none of the suggestions has prevented the problem. On the other hands, I should be happy because there are some people with Xperia V whose phone hangs four times a day!! I am very surprised because apparently this problem occurs for Sony Xperia models more often than for other brands. I hope the problem to be a software related one and to be solved by an update fix, though some Xperia T owners who have updated to JB still face different problems. Please let me know if you too own an Xperia TX and have faced this annoying problem.
Many Thanks
Actualy you are the second owner of tx to Face SOD dont expect much replays here

I am not sure if it is just your firmware because I am on. 197 and no problems. Most people are on. 197 as well so probably not many with that problem. You can try doing a reset through pc companion and that might fix it. It seems to work for various issues that have come up for others.

I had 3.212 when I bought the phone. The phone is being updated to JB right now and I wish the problem would be fixed by this update.
i got my TX a couple of day back and root/flash to FXP213 now. I have tried FXP208 to 213 and this SoD occur in all version of ROM.
i;m trying to get the log for the ROM guy to take a look. I've trie dth wifi off too but still SoD. I notice if i left the phone in sleep mode for over 2 or mayb3 hours, the phone will juz sleep to death.
Actually i have been getting SOD since a couple of weeks on my TX. It happened when the phone is charged overnight.
Another thing i noticed is that each time i reboot the phone after the SOD, it says my my SD card is unrecognized and if i want to format it.
I just took out the SD card for the time being thinking it was causing the SOD.3 days since i removed it and no SOD yet. Any ideas?

Hi,
One of the guesses about the causes of the SoD problem is in fact SD cards. However, there are reports about having the problem even after taking out the SD card.
Have you updated your firmware to JB? Since I updated mine 5 days ago, I haven't faced SoD (touching wood!).
So, I recommend you to upgrade youlr phone if you haven't done so.
By the way, I vaugely remember that those who complained about the SD card cusing this problem, recommended to use SD cards of classes 2 or 4 (and not higher classes).

using ICS 3.212 a month
never facing any SoD
using from 3.212 Russian ftf
and I'm using sdcard 32 GB class 10 without any problem
never hear any information, that higher sd card class give error or SoD to some phone, except for bad sd card. . .
I have been having a similar issue with my TL ever since I upgraded to Jelly Bean about a month ago. For the first two weeks everything worked great and I loved the new update, but now seemingly out of nowhere my phone is starting to act up. At seemingly random times my phone will either freeze or hang or just generally not respond, the navigation buttons disappear and holding down the power button will not let me shut the phone down. The first few times it happened a message would pop up telling me that some process or app is not responding and I have the option to either wait or force close it. Normally I just tap "Ok," and then a slew of messages pop up, basically every process and app crashes simultaneously, forcing me to restart by holding down Vol up and Power. When it powers back on everything works fine again, but sometimes it will do this as much as 4 times a day. It doesn't seem to matter what I am doing at the time or what apps I have open. Sometimes I will go to unlock my phone and it will be stuck on the lock screen (I can lock and unlock the phone fine but no navigation buttons are visible and I can't tap on anything). It seems like now it will just say "Xperia Home is not responding" and I am again forced to restart.
Not sure if this is what you mean by SOD, but it is quite frustrating seeing as everything worked flawlessly about two weeks post updating.
I am using the Xperia TL (LT30at) 4.1.2 build 9.1.F.1.120 Kernal version 3.4.0
Locked base band since it is the AT&T version
Never tried rooting or modding my phone

are you using custom ROM?
I flash to FXP and i get endless reboot and freezing. I like what the folks at FXP does but i can't seem to solve my problem after a week. I just flash back to stock ROM and (god forbid) i have not seen any reboot or freezing the past 8hrs. if u are on custom ROM, consider going back stock.
I am on 9.1.B.0.411 (4.1.2 Jelly Bean) and no problem so far

Sorry for the late reply.
Yes am updated to JB and rooted.
Since i removed the class 10 SD card, No SODs....not even once.
Only thing is that sometimes, when unplugging the charger, the phone does not get the event right away and charging light stays on. After a couple of minutes it goes back to normal.
At least no SODs....

No, like I said I have never tried modding or rooting my phone. I am on stock JB firmware from whenever I updated my phone a few weeks ago. ICS never had any issues like this, JB never had any issues until two week into the update. I'm just confused as to what happens to make these issues occur, I mean, everything was working fine and then for no reason something is causing my apps to crash and my phone to freeze? Doesn't make sense to me...

[Q] Sony Xperia T keeps restarting

hi,
Ive got a problem with my SXT. It kept restarting randomly during the day. I rooted it before and was everything fine till one day. Now I cant use my phone cause it keeps restarting all the time. When i switch it on i cant evan touch the screen without restart. Ive flashed few roms already, stock ones either and nothing helps. I also wiped all data, cache etc.
Really strange problem cause phone works fine when its charging.
Has anyone any idea?
ps. repair via pc companion didnt help too.
Thanks.
Does your phone have CWM? Just wipe cache and dalvik cache
Or you can repair your phone by using PCC/Update Service

did you check the sim card ? , sim card broken also cause automatic restarting
sorry for my bad english
Hi,
No, I didnt check it. Will do ASAP.
btw. Ive updated my fw to the newest one.
edit. sim card seems to be fine. :/
SIM card placement causes random restarts. Make sure it's on their seated properly and securely.

Having the same issues
Only my phone is also freezing even after repairs using both the PC Companion and also SEUS, reformatting my sd card and also a return to Sony.
SIM card is original Micro Sim It is crashing anything from 5 to 10 times a day, with data and/or wifi turned on. Even with the data and wifi turned off I am getting restarts.
Wondering if returning it to Sony did you any good dajbanana? or whether I need to raise the phone as faulty to the point it needs replacement with Sony GB?
you are using a kernel what is not ment for the rom? i mean, using a cm10 kernel on stock rom for example.

or a new phone?
So the only solution for this issue is to send off to Sony for them to replace the battery components? I had a strong feeling it may be battery related. First(and to be last) phone I have owned which hasnt had a removable battery. But then I wasnt fussed as I have never had to replace a battery on a device in my life!
I am with you. My last phone was Motorola Photon, my friend still has it with original battery and it is 2 years old phone.
This is big fail in mobile device.
Even new battery jumps down by more than 100mV, when you make a call for example. I will try again when it reaches 3,7V (nominal voltage).
It is even worse. About 160mV dropdown when starting a call.
i think the battery was a problem for me to it crapped out and i think thats also a reason why it wont work so goodbye sony hellooooo google/lg :laugh:

Call Bug

Has anyone encountered a call bug where I can't hear the other end and they can't hear me? I've noticed it lately and I don't know if it's related to the recently released kitkat update. I've cleaned installed the update numerous times to no avail. A temporary work around is turning off the phone and rebooting and calling back but it doesn't always work. This is what makes me feel it's a software bug as apposed to a hardware failure.

Take a data backup and do a factory reset.
If that does not resolve issue flash stock firmware using flashtool
