hi everyone....
my brother updated his xperia tx to jelly bean using flash tool before 3 hours... nothing showed in flashtool or the phone about any problem in flashing
in the last hour the phone started to restart & freeze
it's freezing suddenly & you cannot do anything but taking out the battery
can a factory data reset help?? also we have a backup on PC companion so is it recommended to return it on the phone??
Try repair option in PCC.

Did you do the repair or did you restore the backup?
Click on the update software option and then when it says you have the latest software click on repair my firmware

which one! I asked if you repaired or restored a backup.....
If you repair the phone it should be exactly like a factory shipped phone.
My only other thing to say will be have you got anything in your sd card (Both internal or external) that may be causing this? Any init.d scripts that reduce voltage etc...try deleting the contents of the sdcards and repairing again. (Obviously back anything up you want to keep)

i did repaired twice from PC companion and did once i think from the phone itself, and i don't have Scards its only the phone internal storge..
when i did it first in flash tool it didn't give me any error and then i did repaired it twice from pc companion however whats strange in ICS i never had the reboot problem
and if i remember correctly it only delete the programs etc, but the photos/music etc it never left the phone with both options i did...
so you suggesting to also wipe internal storage and repair to see if it reboot or not? i already have back up for all stuff so it won't hurt to try
thanks alot really for helping and sorry for my bad english ^^;
If you have a backup then try it.
Have you got a bootloop or do you have some reboots? What i mean is, does the phone actually boot up and only reboot occasionally or is it just bootlooping?

Hi,
I bought Xperia Z a week ago and there was update available, I tried to update it, but the phone stuck in boot loop, I solved this via Sony Update Service. So there is new and actual software. It works fine, until the first charge, the charging was ok, but after unplugging I tried to resolve lock gesture, but it stuck and restarts, the restart repeat several times. And after every charging, there are frome three to five restarts and then the phone is available to using.
Unfortunately, the Backup and restore app is not working, it stuck at 8% and then the phone restarts. So I decided to use SUS again, but it doesn't helped. The restarts are still there, no matter if original or non-original charger, so there is no connection to used/downloaded apps.
Is there any help to this issue?
I don't rooted the phone, but the phone is bought as used from credible store.
Thanx for answers
FW: 10.1.1.A.1.253
I'd suggest to restore the phone to factory default and return it to the store. It could be a hardware issue, that the phone receives a to high voltage when removing it from the charger.

for several times after restart?
bump
when I charge the phone to 80%, not full, and then unplug, the phone doesn't restart
Something defiantly seems off. It should not restart. Loke other suggestion it try a factory reset, if that doesn't work u might need to contact Sony for exchange or repair.
Sent from my C6603 using xda app-developers app
try option 2 if option 1 fails
option 1: Repair through Sony Update Service followed by a Factory Reset under settings > backup & resets. (Internal Wipe)
option 2: Flash another FTF file
but then again, it seems like a hardware issue. Suggest you get an exchange if its still under warranty or whatever.

if you bought the phone just a week ago, then why dont you ask your phone-company to resolve the issue. Phone-company is your retailer and from where you purchased the phone.
Why to take risks at your side....

op 1- when it says that your phone is up to date there should but a blue line of words saying something repair your phone if you are having issues, just click on that.
op 2- android development section and some in the general section too.
like i said if you seriously dont want to go through all that hassle just take it back to the shop and ask for a new one and show them that youre pissed off and demand for an exchange or something. Show them how it restarts lol.

1 - oh, you mean PC Companion...I don't think, there should be solution with this, because I tried to re-update the FW via SUS and it didn't work
2 - maybe I have no balls for this...
so, I will claim my warranty for this
thanx for answers guys
LitoNi - so the op1 helped, the problem was in micro SD card, after repair the SD card is dead, but the phone is working well, no restart since the repair (three days), even the connection between phone and linux (MTP) is ok and I can move with files...thanx
Please help me guys, I have no one else to turn to. My parents are gonna kill me if they find out what I did to my phone.
So my phone accidentally fell at school with the bluetooth still on.So I put the battery pack, power it on, but then it started to go on a boot loop i.e.
Sony logo-->Xperia Logo-->color animation-->black screen. But after 3-4 hours, it managed to do a complete boot! But I noticed that the bluetooth wasnt turning on. So stupid me, I restarted the device, then it started to go on a boot loop again. I got home and I tried it a couple of times more with the power and volume rocker combinations... didnt work either.
I even started using pc companion. didnt work (kept on doing the same thing
SUS --> same thing
NOW: I tried it using a different computer so I went to an internet shop and downloaded pcc and sus. I started pc companion... but halfway through the download... MY PHONE RAN OUT OF BATTERY and didnt finish the update. :'( Now, whenever I'm booting the phone, I only get the Sony logo and A TRIANGLE WITH AN EXCLAMATION MARK AND A PHONE UNDERNEATH.....
PLEASE HELP ME! My Phone is a Sony Xperia TX Lt29
Last Version before the crash: JB 4.1.2
No root (Noob here)
please... please. i dont know what to do. thank you in advance to anyone who can help me
calm down.
Charge the phone until it is fully charged.
Download PCCompanion and do a fresh install of it.
Run PCCompanion and choose software update.
Use the option to repair your phone, then follow the instructions.
Let us know how you get on
PS
This will only do a software repair, if something broke because you dropped it (Which it sounds like) you are going to have to come clean and tell your parents to get it fixed.

THANK YOU FOR YOUR REPLY!!! really thank you :'(
I already did something with the phone because I've been doing a lot of searching on the net lately...
I reinstalled the software using Sony Update Service (SUS) and it booted normally! (but sadly it was only during the FIRST BOOT UP) when I turned off the phone to re insert the sim card and micro sd, It started doing it again... but then, after 6 or 7 tries, it managed to skip past the sony logo-->xperia--> logo-->color animation? and do another complete boot
Now I decided to go to settings and do a complete factory reset cause I thought it would fix everything... but it didn't. It started doing the same thing, and I had to give it 10 or 12 tries before eventually booting up again. When it booted up normally, I was even able to play music with it and change the settings like brightness, volumes, equalizers, and even arrange widgets!
SITUATION NOW:I turn on the Wi-fi and it's in a boot loop again and I'm charging the phone up to 100%
(i did the vol.up vol down power combination before charging)
gregbradley, is it because of our slow internet connection??? (it took me like 4 nerve racking hours to finish the update) but sus was able to complete the download and install the software... what the f*ck is wrong with my phone (((( ohgod
AND:
I'll follow your instructions when the charge is complete...... and I'll be back to you with the results.God I hope this works.Thank you again.
Have you tried only partially flashing part of an ftf file. I know when my phone was on the brink of death I discovered that if I only flashed part of an ftf using flashtool that it would work. I think I would check everything that has exclude (ie: Exclude System) and it would work for me. Its not the end of the world though as the phone does work. Just a bootloop. If you can get it into flash mode then just exclude everything except System, Kernel, and baseband if I'm not mistaken.

Thank you for the reply man '^^
um... to tell you the truth, I have no idea how to partially flash a tft file, let alone flashing. O_O (see how noob i am?) its saddening. So am I in the point right now where my phone's problem is unsolvable via pc companion or sony update service??? Plus I've been doing some searching here on xda and I saw this thread about xperia TX users updating to version b 167 and that their bootloaders are now locked.
This is what my phone is exactly doing whenever I try to boot it up:
Sony Logo---->Xperia Logo----> Color waves animation?---> FREEZE-->black screen then the Sony Logo again.
Whenever I try to boot up for the 2nd time this happens:
Sony Logo----> Black Screen---> Phone turns off---> Sony Logo again
(((
You have flashtool yes? If you load up like you're going to flash a ftf file. Once you click to load up the ftf file it'll pull a menu where you pick what you want to flash. On the right side of flashtool that's where the exclude part is. That's where you have to check the *exclude option. The same thing happened to me when I accidentally flashed a T cm10 rom on my phone. I had to partially flash a ftf file to get it to boot. It should work but since you're not familiar with flashtool its going to make it a bit harder for you in the end. :/

just let it plug in with the charger and keep your phone on for day, usually that will fix it after a few hours with that logo running
Use a battery charger, charge for at least half the entire batt and then follow the thread on flashing, download some files while charging to minimize downtime

Hey guys...... ))))
First and foremost, thank you for all your replies.. really helped me a lot (
It's okay now guys! '^^ I re installed the software via Sony Update Service and it worked. At first I thought the phone was a goner cause it didn't manage to do a complete boot right after the installation. (Phone was stuck on the Sony Logo) But then the next morning, I tried it again and it worked!!
BUT: What I fear now is that the phone might suddenly crash again if I turn on the WI-FI (just like what happened in my previous attempts) If the phone crashes, I fear that the phone would start going on a boot loop again.So basically, I'm just using the phone for media purposes only i.e. Walkman, Gallery,Camera, Movies.
Any thoughts on this, cool, awesome people of xda? '^^ (cant update my apps and google now f*ck)
just.. sad. I miss Flipboard,Modern Combat 4, My Daddy Was a Thief, Real Racing 3, DEAD SPACE (((
one question...
Did something broke inside my phone when it fell?? If yes... WHAT EXACTLY IS IT?? why is it behaving this way??? Why does it keep on boot looping??? should I go and let an expert open it????

Hi my friends.
Today was very bad day for me. First my bird died, then my phone stops working and i stuck in elevator. I need your help. Afternoon i want to call my buddy for lunch. Everything starts after lockscreen. When i call him phone wont connect to operator then it says no connection and stuck at dialer. I push power button to get lockscreen and it frozen for while then it locks and i opened lockscreen. When i saw launcher phone resets and every time it resets at SONY logo. I flashed my device 3 times or more. I used .233 . 230 and 4.3 . Every time battery shows wrong percentage. Phone opens when i plugged to charge. But if it has sim card it resets. When i disconnect from charger it resets. I try to open USB DEBUGING for install recovery to reset battery info but when i check USB debuging it resets again. You guys have any idea for that problem.
Did you try clean installation?

Find out your device model number
See box or pull tray under simcard slot for model number
Flash ftf for that device
Or just take phone to sony's service centre. The device is new so they will replace it free of cost..!! AND also dont bother telling them about flashing and all...

Yes i have used correct FTF.
Sony is not launching mobiles officially in Pakistan, there is no warranty, and service centre for mobiles
It will be stupid idea from me
But stupid ideas may works
You said no warranty
So unlock ur bootloader and try installing cm rom or rr
And see if from software or hardware problem
Note: 1.backup your ta before unlock
2. If your device have LTE then your model is c6903
If not try to find your model in the setting
If the UK version of FTF doesn't work on your Z1 try other one,anyway don't worry try the other version or use the global version 14.6.A.0.270.

U can unlock your bootloader from
Doomlord thread here follow the steps correctly or you could brick your device ....but u must backup your ta if you want to get back your DRM keys
And then download cm12.1 from the official site
here
After download
1. Open flashtool
2.connect your phone in fastboot by press vol. Up after connect
3.copy cm12.1 to ur pc and open zip file and extract boot.img
4. Click on lighting button in flashtool then click fastboot mode
5.under doomlord word you will find select kernel to flash click and select boot.IMG file...
Don't close the window without checking the log that everything is okay
6.open your device in recovery mode by pressing vol. Down
7.wipe factory reset and cache then install update from internal memory the find the cm12.1 zip file and install it
.....
Hit thanks if that help you
did you know if the phone was repaired? like for a broken screen?
when i broke mine, and after fixing it, i experimented really low wifi signal. After a second trip to the technician the problem was fixed. It really has to do with the re-ensemble of the phone.
