I updated my Sony Xperia T to 4.1.2 a few hours ago via PC Companion 2.1. Everything was good until I restarted my phone and it got stuck in the screen with white triangle and blue bar (after the Sony logo). I waited but nothing happens.
I've tried to force restart using power button + volume up (switching off using the power button alone doesn't respond) several times but it still get stuck in the same screen. I was able to repair it using PC companion and SEUS (both were successful) but when I turned on the phone the problem still persists. Restarted several times but to no avail. I cannot use my phone right now.
What seems to be the problem?
My phone is less than a week old, unlocked, stock and not rooted. I will try to flash 4.0.4 back using flashtool coz it was working fine before the JB update.

I have read that this process can take some time, flash a rom and give it at least upto 45 minutes, if it is still not working maybe you have a more serious problem.

Re: [Q] HELP! Xperia T does not boot after JB update
I had this before, when going from 303 to 195.
Flash back the exact last full firmware you had prior to jb, if it was custom use the ftf the Rom is based on, it should boot, reset, then do the update again.
It took 35 mins to complete, I thought it was dead, once you get that screen, do not interrupt it or it can't complete and you need to start again.

OK, I was able to fix it and replicate it once but there's no certainty that it will not happen again once I restart the phone.
Here's what I did...
Since .233 did not work, I tried flashing the older firmware which is .303 - It worked!
I tried flashing .233 again to test if it has something to do with the firmware but it flashed without any problems!
I checked with PC companion to update to 4.1.2 but no update is available (since I used the UK firmware) so I flashed using the ftf file (.489) found here - it successfully flashed to 4.1.2!
HOWEVER, when the phone restarted (after inserting the sim card) and that's when the problem happened again! It stuck on the same screen. That's how I first encountered the problem earlier - the first reboot after updating caused for the phone to get stuck to that screen with white triangle and blue bar.
So I repeated the same process again (flashed .303 but skipped .233) then flashed .489 successfully but I DECIDED NOT TO RESTART THE PHONE this time. I'm not an expert so I don't know what's the cause of this??
My phone is working fine right now. Probably I will try to reboot the phone after 3 days to see if the issue comes back again.

Did the problem occur right after you updated? Or when you rebooted the phone for the first time after the update?
Mine was ok whether I updated via PC Companion or flashtool - the problem only happened when I restarted the phone for the first time after the update. So I tried not to reboot the phone on my third attempt. It's working fine now on 4.1.2. (as long as i don't restart it probably).
You can try the process I explained above and let us know!

The solution for white triangle is, like DooMLoRD said, formating internal storage

When more accurate to format the internal card?
Give me step by step if you think you know the cause of the problem.
Thank you in advance.
Fix to get JB Running
I had the exact same problem, a white triangle after flashing the JB update.
Here's how I solved it:
1. Flash a .303 stock firmware
2. Turn on your phone without Sim card and without MicroSD
3. Complete the Setup Guide (just pass the 7 steps).
4. Get Ready to flash the JB update (.489 I think)
5. EXCLUDE BASEBAND BEFORE FLASHING IT
6. It should work now (is working perfectly on my Xperia T since yesterday)

I mentioned in my process above that I will wait for 3 days before restarting the phone but I did it anyway to test your process. It didn't work for me.
I followed ALL the steps but after the phone restarted (when sim card was inserted) it got stuck on the same screen again. Have you tried rebooting your phone?
Looks like I'm gonna stay with .233 for now until this gets resolved.

How do we do that in JB?
I noticed that after I flashed the .303 firmware the phone asks that internal storage be formatted (there's a notification in the notification bar). So I did that. But after updating to 4.1.2 the problem repeats again after the first reboot (stuck in the screen with white triangle).
Sounds like my problem has been solved. :good:
I repeated the process by Samper27 (except that I didn't remove the sim card; I don't have an sd card).
After updating to 4.1.2 I cleared the internal storage via the settings and performed a factory data reset - my phone restarted without any problems. I could switch it on and off now without getting stuck in that screen.
Great!

Glad to hear that! I don't know the change with the SIM Card, for my it worked like that and I have turned off and on several times. After doing that I lost my APN configuration but a quick google search and BAM, everything working smooth and battery life is a little better than before.
You should update the post to let everyone know that the problem is solved

I have the same problem with this white triangle. The only firmware where the phone starts is .303. All other firmware doesn' start anymore.
I tried the process by Samper27, but it doesn't work for me. Could you please tell me which firmware of .303 and JB 4.1.2 you used? And what do you mean with factory data reset (Hold down the power button and volume up for 10 sec?)
Thanks
Even I gotta same problem. But my phone's screen is now blank, no LED no warning Triangles
Hey everyone, I installed recovery on my phone and it worked fine but after doing so I tried to install a ROM. This ended up with my phone being bricked and so I flashed the original FTF file and now it works fine again. I rooted the phone after this and installed recovery and it said it installed properly with no errors. I then tried to boot my phone in to recovery by pressing either volume key when the green led shows up with the sony splash screen but nothing happens. I've tried it loads of times using both up and down volume keys but it does not go to recovery anymore. Any help?

sorry but what recovery are you using
TWRP/CWM I've tried both of them neither of them boot up the phone just boots up as normal even if I press the volume keys. I've installed the CWM for locked bootloader now though and it still wont work, that being the case my phone is a locked bootloader.
what device are you using and which recovery?
i rmb ZL has issues with CWM recovery like this.
Z, havent encounter any yet.
If you cant boot into recovery then try installing it again.

have you got superuser/super su installed and working ? when flashing recovery supersu asks for ADB approval
Well it would be an Xperia Z being in this category of the forum? But Ive tried re-installing and removing completely and installing again. Each time it seems to install correctly but even if the green led comes on at start up it wont boot in to the recovery mode
I even tried using XZRecovery to install it on the phone itself but that didnt let me boot in either

Yeah sorry for not answering previously I do have it installed but as I said, I gave XZRecovery su permissions and it installed TWRP recovery then I rebooted but this didnt work either. I just tried Recovery Reboot from play store and it just gives my phone a normal reboot

Okay try installing this one dont know of anyone which this hasnt work for, before go into supersu and look at app's, has ADB got a green or red hash
I tried that one before and it didn't work. Just checked my superuser and it seems it doesn't even have ADB listed, just some rooted apps I've used. I tried setting it to always allow in preferences but that didn't change anything.

do this
1-flash "another" ftf file
2-repair it with sony update service
3-go to settings > backup and reset > factory data reset (internal wipe)
4-root
5-install CWM
do not try to restore your previous rom or whatever. especially when youre jumping from one rom to another.
Start fresh.
This will probably work but I used the unbranded ftf file on a clean install so im not sure how much differentit'll be

I tried to do this but when I connect my phone to a pc nothing comes up, no pop-up, nothing on the phone, it doesnt even charge. It does charge however when I put it in a plug socket.. I think this could have something to do with it in the first place, my problem still isnt resolved what else can I do?
Are you stuck at step 1?
Try the newest flashtool (I think people are having issues with it, but worth a try) or the v4 flashtool.
And try another ftf file, don't use the same one that you used, or trying to use.
Hi I need help please, My xperia is Rooted and I flashed for the small navigation buttons,
They disappeared, Fortunately Backup was made.
But cannot get into recovery to do backup.
I get: "Unfortunately, System UI has stopped" and I cannot do anything but switch the phone on and off.
Very frustrated and scared I broke the thing.

do a reset?
You don't need to boot the phone up fully to get into recovery.
Just press whichever volume key is applicable when your phone is starting up to boot into recovery, then restore your backup.
Unless I'm missing something obvious. :what:

Restarting the phone just brings me back to the same error, and cannot log in to recovery from boot.
Tried holding in the up volume key during boot, the light flashes green, then off. then continues to boot as normal.
Assuming you actually flashed a custom recovery, you do not hold the volume key. You press it when the LED flashes green.
If you definitely cannot enter recovery, then try flashing a stock rom with Flashtool.
Download a stock FTF from the general section and follow this guide - How to flash stock roms with Flashtool
You will not lose your data if you follow the guide correctly.

Thank you much appreciated!
A quick one for you too...
I had similar issue. When the phone has booted although you can't see anything, you can still hard press the home button, push up and open Google now. From there you can access xz recovery, if you have it installed? You can then choose to boot into recovery....
If not installed you can open play store from Google now, install xz recovery and do the above. You can then recover your backup.
Xperia Z

Any help would be appreciated
Help, First time flashing a ROM on a Sony phone. I have experience flashing, unlocking bootloaders and rooting, etc... but I normally do this on my Samsung phones.
So... This is what happened. I recently tried to change my Sister's Xperia Z (C6602) ROM so I could try if I could get 4k video out of its incredible camera. But I didn't have any knowledge on how it is done on a Sony phone. I researched on various sites how it is done.
First I saw NUT's dual Recovery and I downloaded it so I could get Recovery on the phone. I downloaded it and I tried using the third option which includes rooting. But I couldn't get it to work. It seemed like it couldn't root the phone properly. So I tried using vRoot (failed), tried an utility that I found while researching and I got it to root. Went back to NUT's dual recovery, installed Recovery, everything wen't excellent to this point. Sister didn't made backup so I couldn't flash the ROM yet.
Researched how to Unlock the Bootloader, saw that Sony let developers unlock the bootloader and I did it using fastboot and the code from Sony, the wrong part is that I didn't backup the TA Partition (Had TA Backup utility XDA site open on chrome but didn't use it since I thought nothing would go wrong if I didn't make a backup of the TA partition) and yes I lost the DRM keys... After this I found out that loosing DRM keys means no Bravia Engine, Music ID, etc... (I hate you SONY )
After loosing DRM keys, I was worried that my sister would kill me, so I searched trough XDA and found that you could get some functionality back from recovering the TA partition and flashing a zip from jimRnor but I needed to flash 10.5.A.0.230 ftf using flashtool. So I did it. relocked bootloader, flashed 10.5.A.0.230, booted to 10.5.A.0.230, turned off the phone, unlocked bootloader using flashtool, used recovery to flash the zip, and done.
So this is the part where I made the phone not work... (And I deleted some of my sister's photos because unlocked bootloader without backing up woopsies)
Sorry for the long story...
Wen't to recovery, tried to flash iHackers v5.2 but somehow the file didn't downloaded correctly, got some errors during installation and I turned off the phone to go check what happened that I couldn't get the zip to flash. And by turning off the phone. It somehow got corrupted or something and now the phone won't turn back on. It stayed with the LED on red. I found it strange so I pressed Power + VolUp for like 5 seconds and it turned off, and then I tried turning it on again and nothing happened. Tried different combinations and nothing would happen. lastly I tried using Power + VolUp + VolDown for 20 seconds and now it is flashing 3 times a red light on the LED. and this is how it has been for a while.
So please, has anyone had any experience with this type of problem, what should I do and what I need to learn for the next time.
P.D. Yes, I didn't know that Flashtool could do everything from rooting, backing up TA partition, unlocking/locking bootloader. I found out after I had some time using the utility.
P.D. I can't get access to neither flash mode or fastboot mode, PC won't recognize the phone.

Hello, I have been searching for a way to install TWRP.
So far I have tried ADB push with success, but just loads back to rom when it reboots.
Its annoying the hell out of me, I have got ROOT, BOOT Unlocked.
If any one has any ideas please feel free to post it, no matter what it is.
how about installing from the playstore Twrp manager?
or YouTube there are a lot of videos to install it
Thanks for the reply, tried using the twrp manager, it just restarts the phone and goes back to the rom after install and when I try to restart to recovery it just reboots back to the Rom.
When I hold Volume down + power it only shows a green android icon for a couple of seconds then restarts back to rom.

Try install XZ dual recovery by nut here XZDualRecovery_2.8.26 , hope its help
Thanks for the link to the other recovery. I fixed TWRP not booting, by using Sony easy root and once I used that, it booted TWRP.
