[Q] Xperia T - won't go past sony start sreen

Hi all, I'm new here and very much a novice when it comes to phones, operating systems etc so excuse me for the noob question and complete lack of knowledge...
My Xperia T developed a microphone fault whereby nobody could hear me when I called them (incredibly faint). I had the phone repaired at a local repair shop. Almost immediately upon receiving the phone back it developed a (What appears to be very common) battery fault, whereby it would reach 80% then shut down, restart, shut down, restart......
So, before returning it to the shop for further repairs I attempted a repair using the sony software. Half way through this repair the phone shut down!!! PC lost communication and I was left with a phone that simply displayed the 'Sony' start-up logo.
I have now returned to the shop and they have installed a new battery but are unable to get communication with the phone via the sony software (so basically they dont appear to be getting any further than me!). They are saying it is beyond repair - but I find that hard to believe? Surely it is just a software issue?
Can anyone advise what can be done? I am reluctant to write this phone off - surely it can be flashed with a new operating system or whatever needs to be done to what is essentially now a 'dumb' device?

This is the way to fix the software issue, ALL YOU DATA WILL BE LOST. And i'm not responsible for anything might happen to you device . DO THIS AT YOUR OWN RISK.
Google xperia t .145 ftf file
Google flashtool for xperia
Download them
When you have installed flashtool, go to its folder, install drivers (tick the TX, flashmode and fastboot drivers boxs)
Open flashtool, click the lightning logo, select flashmode
Put the firmware file you've downloaded to the firmware folder in flashtool folder.
Connect the phone in flashmode, hold power and volume up until it vibrates 3 times, now hold the vol down, plug your phone in the computer with flashtool running, you will now able to flash the firmware.
Good luck man.

Thankyou very much for your reply!! Thats what I need, a step by step muppets guide!
To be honest I couldn't care less about any data, I'm way past that stage - if I can just have the phone working again I would be a very happy man (I'm fairly desperate as you can probably tell, Im running my business from an ancient, failing HTC desire following weeks of the shop having the sony!). I can't really afford to write off a phone I paid good money for 6 months back so need to have a go myself.
I am collecting the phone today so will give that a go.....

So I had a go at the above - got the flash tool installed (Emma?) etc and managed to get the software to see the phone - unfortunately though I had neglected to mention the phone is locked to a particular network, which Emma politely informs me.
So, I have attempted to follow unlocking instructions as per the sony instructions (on their website):
But I am stuck. I was getting nothing when using the volume down button and connecting. To get the computer to see the phone I have to press and hold the power button, the red led starts blinking 3 times, repeatedly. This causes windows to recognise the phone when plugged in via usb, but I was not being asked for drivers (as per sony step 13). I found the device in device manager and uninstalled drivers in an attempt to force this. Now all that happens is the device appears in the list as 'S1 Boot Load' with a yellow exclamation mark. However I have then tried installing drivers manually from the location where I copied 'android_winusb' to, but this does not work.
To compound the issue I think the battery problem is causing the phone to cycle. when connected the green led lights up for a bit, but then goes off, then back on, then red.....repeatedly. The device only appears in device manager as 'S1 boot load' when green. This gives a very short window to try to do anything.

Wrong flashtool, download the one from the Dev section and flash a stock FTF

Oh right, first mistake then. The phone will still need unlocking first though I assume?

I've been dealing with a similar problem. When connected to a wall charger is your phone cycling from Green to Red and keeps doing that? Also have you installed Sony PC Companion maybe your phone will get recognized from the drivers in that install.

Same problem
Hi, I am currently having the same problem. I have tried to use flashtools and I've got all the necessary drivers (I think) but once I put hold power button and vol+ (3 vibrations), then press vol-, connect to pc via USB and I get a temporary green led, which goes after about 5 seconds, and then my phone disconnects from my computer again. I really need my phone to work Could someone out there please help with this! I would really appreciate if someone responded very soon as I would like to get this sorted as soon as possible. Flashtools gives me these messages:
22/012/2013 23:12:07 - INFO - Device disconnected
22/029/2013 23:29:07 - INFO - Device connected in flash mode
22/029/2013 23:29:18 - INFO - Device disconnected
Also one more thing i'd like to add.. Once I go into that BLU thing, it keeps on asking me what device I have, so I select Xperia T and then it gives the following messages:
22/052/2013 22:52:26 - INFO - Your phone bootloader cannot be officially unlocked
22/052/2013 22:52:26 - INFO - You can now unplug and restart your phone
Might this have something to do with it? Any suggestions would be grateful! I've been at this for hours now and need to get this sorted
Thanks to any kind person who helps fix this!

[Q] Xperia SP Bootloop in Sony logo + not detecting in flashmode to flash stock rom

I've got a xperia sp, unlocked bootloader device. I've installed CWM recovery. Recently I tried to install CM 11 and I changed the update binary file since I couldn't flash the rom due to set_metadata error. ( A fix I found in a XDA Thread ). Now the device is on a boot loop at sony logo. I had this issue previously and I just flashed my stock rom using flashtools.
Now the issue is, when I connect my device to the pc while holding the volume down key, the green light ( indicating the device in flashmode ) comes up and it stays for few seconds and the device boots normally going into the boot loop.
I have installed the drivers for xperia, since I rooted and installed the cwm recovery on the same machine the day before. I prepared the ftf file and when flashtool prompted me to connect the device I connect. Windows does not indicate a device connecting with the usual sound.
I tried every possible way of connecting the device in flashmode but it doesn't stay for more than 5 seconds. The same for fastboot too.
any ideas on how I can recover my devce without giving it to a service center?
Thank you.

Firstly, power off the device if stuck in bootloop.
Take off your back case. Take a pen,pencil or similar object. Hold the small yellow button at the bottom of the device with the nib of pen or the object you are having. Hold that button until the device vibrates thrice
If you have flashtool.. Download stock ftf from http://forum.xda-developers.com/showthread.php?t=2311964 and place it in Flashtools>firmware. Connect your device in flashmode( Volume Down and connect). Click on the Lighting Button> Flashmode and flash. [ BACKUP YOUR INTERNAL MEMORY AS IT GETS FORMATTED]
But note that you will lost Root Access. You have to root your Xperia SP again. And if you have unlocked bootloader then it will remain unlocked. No need to unlock again.

The problem is that I tried doing that! when flash tool requests to connect the device in flash mode, I power off the device and while holding the volume down connect. But there is no sound from pc of connecting a device.! The device turns green for 5 seconds, then starts to boot again. I tried installing the drivers again but the drivers are already there!

Are you able to enter CWM ?

Try this. [ I am not sure about this. I haven't tried this ]
Connect your Xperia SP with pc. And hold that small yellow rest button for 5-6 secs. It should connect your device in flashmode.

It just my opinion. If flashmode does not work why not try in fastboot? Just download any custom rom. Extract the zip file and flash it boot.img. Enter the recovery by pressing vol+. Install the custom rom. After finishing you can try back to flash the stock rom using flashtool.

This seemed to be a hardcore drivers problem. I can't pinpoint you to the right direction as I am not a Windows user (and also prolly lazy to reboot my laptop right now lol)
On your own computer
Open Device Management, and uninstall all related drivers of Xperia SP. These also includes flashmode and fastboot mode drivers. Then execute the "drivers" installer within Flashtool install directory (which is default C:\Flashtool). Then attempt to flash again.
Try on another computer.....
...to see if it works. But make sure to install the drivers first, as mentioned above. Attempt flashing again/
fastboot a CWM-ready kernel
You could also alternatively use a quicker flashing process, which is fastboot WIlliams kernel v7 (the kernel's .elf is in the zip). I can assure it only takes lesser than 4 seconds. For broader steps you may refer here: http://forum.xda-developers.com/showpost.php?p=56907083&postcount=3

The thing is for me
1) I cant see the small yellow button that you are talking about.
2) My device is nto connecting to the flashtool, it keeps on telling me to press the 'back button' -which my xperia sp c5303 does not have.
3) your volume down and connect does not do anything. Apparently there's supposed to be a green light as well and I dont see that.
This question is really to anybody knowledgable about this... Can you help?
I have Flashtool. And the stock firmware in the right place as well. But nothing else seems to be working.
My phone shows the Sony icon when I plug it in to teh computer and press the power button, otherwise when turn it on, it just shows a red light.

1st
I think he means the reset button. It's more copper or gold than yellow.
2nd
Don't look for back button. In the SP, vol down is Flashmode, vol up is Fastboot.
3rd
Press the button before connecting USB, hold it and release when light becomes green.
4th
I would recommend the Sony program "Emma". Make sure you get the latest version. Earlier versions didn't support the SP.
Google for "Emma chip.de Download".

one more thing, its says I need an unlocked bootloader but on some other threads where they were using flashtool they said that having an unlocked bootloader was bad and that it can severely damage your phone. Either way I cannot unlock my bootloader so it doesnt matter. I'll try it using Androxyde's Flashtool first and then yours if it does not work.

It didnt become green, and also there is no reset button, there is only a yellow bit of plastic in this little hole, and it says OFF. But I dont think that does anything.
I think I need some more specific instuctions and need to know where that button is.

Didn't read your bootloader is locked. Then forget Emma! It won't work.
The off button is the reset button.
Do the following.
When flashtool asks you to put your phone to flashmode:
- Unplug the phone
- Turn it off if it isn't off
- Press and hold the volume down button
- Keep holding it!!!
- Plug your phone to the PC. Don't usw usb 3 port.
- Light will turn green, flashing will start

Actually to use EMMA your bootloader has to be unlocked, but if you can't use flashtool or EMMA, you can try the original Sony PC Companion. Go to the repair phone section, identify phone, and it can help you to flash your stock firmware. From there you can restart flashing.of ROMs and all. Worked for me

This would work except for the fact that my phone's bricked. I deleted the system part of the phone using TWRP. So yh.
I have used the repair thing before though, when I deleted the download manager on my phone and literally could not download anything. So I can recommend that definitely.

Have you installed all the necessary drivers via FlashTool? All 3 of 'em i.e fastboot drivers, flashmode drivers and SP (huashan) drivers?
I know its a rudimentary question and you probably have but you'd be surprised how often people get stuck cause they haven't installed requisite drivers.
If the above fails, well you already seem to have TWRP installed so why don't you just boot into it and flash a ROM? Unless you really need to return to stock firmware for some reason, that's a viable solution to your problem.

I think the root is gone, that was part of the thing/whatever I did using TWRP to the system. So using any custom recovery is out of the picture anyway cos it wont work without root and then that's without the fact that I cant access the recoveries in the first place. Every time I try and turn my Xperia SP on, the illumination bar lights up red two or three times and that's it. All the time. Sometimes when connected to the PC it shows the Sony logo, in bootloop.
On flashtool, I made sure specifically to install the SP driver and the flashmode driver. I'm still trying though...

Why did you delete the system via Twrp? Also when you say you can't unlock your bootloader, does that mean you don't know how to or its not unlockable at all? Is your phone being detected in fastboot and is it showing up in Device Manager?
Well if your system's gone, root access is the least of your worries. On the bright side though, your phone's recoverable since as you have mentioned, its alteast showing the Sony splash screen occasionally.
You need to get Flashtool to detect your phone cause Sony PC Companion won't work since you don't have a working system and I read above that Emma needs an unlocked bootloader. Also if your bootloader's not unlockabke, you can't flash a custom recovery and what good's a nandroid backup when you don't have a recovery to restore it from?
If you can't get your phone recognized on your PC, get on someone else's, one preferably running 7 if you don't want to go through all the disable driver enforcement nonsense and install FlashTool, install drivers and flash stock firmware. Like I said, as long as you can see the Sony splashscreen, your phone ain't dead.

Me deleting TWRP was an accident, I dont know exactly how I did it, but I'd attributed it to wiping my system. Or by removing root, which I did somehow. I think removing root, kinda makes a custom recovery useless.
My phone's bootloader unlock permissions are set to no. So I cant unlock it.
And every time I try to flash a stock firmware .ftf file onto it, the phone is not recognised and I make sure to press the volume down button when I connect the wire to the phone.
And yeah, the SONY logo shows itself when my phone is charging. It's been like that for the whole time just on SONY. Also the illumination bar is red. But is it not supposed to turn orange and then green if it is fully charged.
And no, I have been able to flash a custom recovery without having unlocked my bootloader. It's how put TWRP on it in the first place- though I need to find it again. Hopefully, soon, Ill be able to install it and then flash my NANDROID backup onto it.

[Q] Help needed urgently

Hi all,
Not really sure where to post this, so firgured id put it under general questions. I am currently trying to flash android 4.2 to an Xperia Z1 thats currently running 4.4.4 kitkat. - Now feel i should mention at the start, that i am not particually brilliant with android, and am slowly learning the basics.
I am using a program called Flashtool, I have the file that I want to flash over (the 4.2) - I have also gone through the program to install all the drivers. ( I have installed all drivers as i didnt know what i needed and didnt need, and initially tried just installing the z1 drivers ) Flashtool picks up my phone, and tells me what its currently running, it also detects that what version of android i am currently running, but for some reason dosent pick up that ive tried to plug in my phone in flash mode.
The system detects when I start the phone in fastboot mode, but whenever I use Flashtools to try and connect my phone in flash mode, it just keeps asking me to connect the phone. ( I am using Z1 and the standard key is vol down whilst plugging it into the usb cable, however the l.e.d. flashes red and green quickly and then shuts off, cant even be sure that the problem is Flashtools, it might be that i havent put it into flashmode properly??)
any help would be brillant, feel free to contact me via the xda site, or via e-mail [email protected] -
This might be a particularly basic problem to somebody, its had me stumped for days, any help you could give would be massively appreciated,
cheers

Try Older version of flashtool or you are missing some drivers in flashtool folder is file with drivers and you need to check flashtool drivers and z1 drivers and firstly connect the phone and wait to install drivers and next turn off phone and hold vol down and connect without flashtool to install flashtmode drivers and at the end try to flash via flashtool.

If you are sure you have installed drivers correctly then kill any other process on your pc which use adb drivers like pc companion or airdroid etc. Or use other usb port. Or use other pc. Wrong thread though.

Thanks all, have now successfully rooted the phone, unfortunately for me that has yielded more questions than answers loll,
Now that its rooted, its running 4.2.2 and I am wondering if there is a way of keeping root access, but flashing it back up to 4.4.?
Really grateful to everyone!!

If you are afraid of losing apps backup them with Titanium !

[Q] Sony Logo Bootloop !?

Hi all,
So I got this Sony Xperia SP C5303 from a friend of mine which is stuck on a boot loop (SONY logo => XPERIA logo => Orange logo, then screen dims and reboot )
I tried to flash it with FlashTool but nothing, I downloaded the ftf for it and I have installed all the drivers from the flashtool driver folder but nothing, I always get an error on Flasgtool indicating that I must install the drivers
As I said, the phone cannot be booted and I have never connected it to my computer so there were no previous drivers, so what should I do ? (I have Win 7 btw)

Don't know what you mean by all but the three necessary ones are fast boot, flash mode & viskan board drivers. Use the latest version of Flashtool, install those drivers, prepare the firmware and connect the phone pressing the volume down button.

I do have FlashTool the latest version (0.9.18.6) and what I meant by "all" is that when I run the "FlashTool drivers" that comes with the software, it gives me a checklist of the available drivers, I ticked every single one of those drivers, and they're all installed, but still, FlashTool shows an error that the driver must be installed !

You don't need to install all of them, just the three I mentioned. Could possibly be causing detection issues.
Go download USBDeview and see what you got installed. I'd advise you to remove everything Android and Xperia related and start from scratch to avoid conflicts. If you have installed things properly, you phone should show up as something like this in USBDeview -
Normal mode
Xperia SP - USB Composite Device
Fastboot mode
S1Boot - Fastboot Android ADB Interface or ADB Bootloader Interface or something similar.
Edit : Just as I finished posting, my SP wasn't getting detected in adb. Why? Because I had connected my brother's Xperia ZR and for some reason my phone doesn't like other phones being connection on my machine It was showing up as Linux storage unit or something. Reinstalled drivers via FlashTool and everything's good again. Drivers are finicky things man.

LOL, well I've got a little update
I flashed the phone first with Sony PC Companion, after it finished, I plugged out the phone and started it, it took some while to boot, the screen showed up but it wasn't responsive, after a couple of seconds, it dimmed and it rebooted and now it's back to the same old issue (SONY > XPERIA > Orange > Reboot).
Right afterwards, I flashed it using FlashTool (This time it worked perfectly, which is weird) but still nothing, after finishing the flash and plugging out the phone, it's stuck on the SONY, XPERIA and the colorful waves bootanimation ....
I've no idea what is wrong with this thing now

Well the fact that it's getting there means there isn't anything significantly wrong with it.
Have you tried rebooting it using the off button at the back? Sometimes it does that the first time booting into the ROM. Just press and hold the button for a few seconds with a pen or a toothpick to reboot the device.
You could also boot back into recovery and do a factory reset just to see if it helps the cause.
You can also try different firmware versions. Maybe 4.1.2 instead of 4.3.
BTW is the boot loader unlocked on the phone?

I did try the tiny yellow OFF button in the back several times through the flashing process and whatnot, but nothing .
I tried getting into recovery mode but it just won't it just keeps on doing the same bootloop as before
I dunno if trying a different firmware would help, I highly doubt it but I will try it as I got nothing to lose
I've no idea what that boot loader is but I DID try to unlock it using FlashTool's BLU and I got this in the log "07/029/2015 21:29:05 - INFO - Your phone bootloader cannot be officially unlocked"

You need to press either the volume up or down button a few times when you're booting up to get to the recovery. If you have done it right then after the Sony splash screen you should go into the recovery.
Boot loaders need to be unlocked to be able to flash custom recoveries & ROMs but forget about unlocking the boot loader for now since you do not know what it is and without your phone working there's no way of knowing for sure of it can be done or not.
Like I said try doing a factory reset in the recovery or a different firmware to see if it helps.

Well, I just did some research and I found out that Sony phones do not have a stock recovery mode . . . So there's no recovery mode for me (I did try but nothing)
I'm going to try to unlock the boot loader using SDK and if nothing happens, I'll try to flash it with a different firmware

Oh damn I forgot you had flashed stock firmware...yeah Sony phones ship w/o a recovery. Even if it had one, it wouldn't be much use other than wiping cache & dalvik, factory reset and installing official signed updates. A big reason why people unlock their boot loaders to install a custom recovery.
Before you proceed try to understand as much as you can about what you are doing. Don't go in half cocked and create more problems for yourself. The main problem you face is that you don't have a working system so
a) you don't know whether you bootloader can be unlocked to begin with and
b) even if it can be, you can't take a TA backup to save your warranty cause your phone's not working. If you don't take the backup before the first time you unlock, your warranty's pretty much gone forever.
If you still wanna proceed, check out the link below. Another poster wanted to unlock recently so the thread below contains boot loader unlocking instructions. There are four I have listed. Read carefully before you proceed.

Xperia SP almost dead after flashing. Need help.

I flashed my Xperia SP with from Jellybeam to CM13 rom. I didn't create any backup, wiped clean everything including cache using twrp recovery. While the setup installed CM13 without any error but I downloaded the wrong gapps and the setup didn't accept those. So I chose to reboot the cell and since then it just stopped responding. Although it is showing the green led while plugged in via USB, it won't start in neither fastboot nor recovery mode.
I'm stuck here and have no idea what to do.
I tried installing PC companion, flashtools, SP flashtools, emma, everything. None of these detect my cell. I'm using Windows 10 (64 bit) and am at a dead end.
Any help would be appreciated.

UPDATE:
I managed to flash it with errors and now it's stuck in a SONY logo bootloop. Its starts, shows SONY logo for a while and then turns off again. Again it's not getting recognised by any flash tool, sony companion etc.
Help please.

Installed the driver and flashed it with a rom but it's still stuck on the SONY logo. One more thing, It's bootloader wasn't unlocked when I messed up at the beginning. What can I do to save my phone?

Whether I try to flash it or unlock, phone boots up before the process is completed. I'm completely stumped here.

Hi! Still have the problem? I faced the same two days ago when I tried to change the on on my SP. But finally I could save the Phone by searching a bit on the net. Pls tell me if matter is still on and I try to translate the steps to english.

Yes, still stuck there. Can't flash it because phone boots mid-process and flashing aborts. Please help me out here.

Hey!
Sad to hear, but maybe (I hope) this method will help you. Basically what you will get is an original Xperia SP with 4.1 android as it came from the factory.
You will need:
1. Sony Mobile Flasher by Androxyde" version 0.9.18.6. Don't know if newer version came or better. You can find it here in forums. http://forum.xda-developers.com/showthread.php?t=2489955
2. The basic ROM "12.0.A.2.254".
The method that helped me:
SP turned off. Cable not connected.
Start Sony Mobile Flasher (Flashtool) , give administrator rights.
Top left cornet click on the bolt and choose flashmode, then in firmware selector you can find and select the downloaded ROMs and kernels. Choose the official 4.1 (12.0.A.2.254). Click falsh so it starts to proceed.
Then a windows appears called "wait for flashmode".
Now. Grab your turned off SP press volume down and connect the usb to pc. Keep holding volume down button till flashtool starts to upload the system. (Hopefully it will be fast enough, and phone will not turn on. For me it was)
After flashtool is finished you will see:
09:50:53 - INFO - Flashing finished.
09:50:53 - INFO - Please unplug and start your phone
09:50:53 - INFO - For flashtool, Unknown Sources and Debugging must be checked in phone settings
09:50:54 - INFO - Device connected in flash mode
Unplug and start the SP
If everything went as planned you have your phone back with stock 4.1 and 12.0.A.2.254 kernel.

Thanks a lot brother. At first it didn't work when I flashed it with the latest version of Flasher. Then I installed the exact version you mentioned (0.9.18.6) and phone didn't boot during the flashing and now it's back to normal with the default 4.1 stock.
Thanks a bunch, you're a life saver for me. :highfive:
