[Q] Boot loop with purple LED?? - Sony Xperia T, TL, TX, V

Hey guys,
A while back I tried to root my Xperia T and putting CWM on it. Something went wrong and I don't exactly know what. It went into a boot loop.
Every time it starts up, the LED turns purple for a couple of seconds and it reboots again. I waited for the battery to drain and honestly forgot about it.
Now i found it again and i want to get it out of the boot loop. The wierd thing is that I can get into ClockWorkMod recovery but nothing else. When in startup and I push VOL- it goes into CWM without a problem. It's like the normal firmware is missing and it can only get into CWM. Is this possible?
And i am trying to flash the stock firmware on it. But when i try to connect with my pc (drivers an flashtool in place and working) it doesn't really seem to connect. It worked 1 time out of the last 5 tries. But when i tried to flash, it said ERROR. The phone get's the blue LED when i connect it. but this only workes if my timing is exactly right in the boot loop. I will try to manage it again to get some screenshots.
I'll update when i have screenshots and everything (with the proper ERROR code)
In the meantime, does anyone have any clue of what is going on?
Thanks:good:,

Blue LED means you're in Fastboot mode, you need to put it into Flashmode (green LED) for it to work. If Vol Down puts it into Fastboot mode, then Vol Up would put it in Flashmode (I assume). Considering you're talking about timing, then it seems you don't know how to put it into Fastboot/Flash mode properly.
1.- Turn off your phone.
2.- Connect the USB cable to your computer
3.- Open Flashtool
4.- Press down the corresponding volume button (keep it pressed), and connect USB cable to your phone
Alternatively, you could also connect your sdcard to your computer and copy a flashable ROM to it, then flash it in recovery. It seems your /system partition/folder is either incomplete or damaged.

Hey,
thanks for the reply.
The problem is that i can't turn the phone off. The only way it stays off is when the battery is dead. Like it is now. I have just tried what you said. VOL- gives the green LED for flashmode. But even when it is in flashmode and connected with my pc(pc also said it's connected) it keeps rebooting. So the connection switches on and of every 30 seconds or so. I found out that there was a wrong file in the flashtool firmware folder. after trying to flash the standard firmware it tried to do something else. I've removed the file and set it up right.
When it was connected (green light and everything) I got this;
"09/025/2014 17:25:27 - ERROR - (Bundle.java:440) - Cannot delete C:\Flashtool\.\firmwares\prepared\system.sin"
"09/025/2014 17:25:39 - ERROR - (Bundle.java:440) - Cannot delete C:\Flashtool\.\firmwares\prepared\system.sin"
And that was all. I will try again in a few minutes, but maybe I missed something.
[EDIT]
Tried a few more times. VOL- to flashmode, connected with pc. Flashtool starts loading the green bar.
After a couple of minutes it stops and Flashtool says this:
09/021/2014 18:21:11 - ERROR - (X10flash.java:523) - Read error :31 : Een apparaat dat op het systeem is aangesloten, werkt niet.
09/021/2014 18:21:11 - ERROR - (X10flash.java:524) - Error flashing. Aborted
(Een apparaat dat op het systeem is aangesloten, werkt niet. -> English -> The device that is connected to the system, doesn't work.)
And the thing that irritates me most of all is the X10flash.java:52.. part. Why does it say X10flash when a Xperia T lt30p is connected en i'm trying to flash LT30_9.2.A.1.205_CH or LT30p_9.2.A.0.295_Generic IT.
I can't wrap my head around it.
I put some attachments in here so you can see what I see. Can someone see what I'm doing wrong or not doing at all?

I seriously do not know how or why. But i did it. Flashtool did not give a log or anything(with previous phones i saw a long list.) it looked like it did not do anything. but the phone is booting into android as we speak!
Thanks for the help Antiga Prime! not a lot, but enough!:laugh:
Now i need to find out how to delete all thisXD

Take the battery out and in, then leave it connected to the charger for one full day, don't do anything with it.

Xperia T doesn't let you take out the battery that easy. But it's fixed. I just need to know how to delete this thread

Stuck at rooting ZR 4.2.2

Hi. I have been following this guide: http://forum.xda-developers.com/showthread.php?t=2392865
And im stuck at step 9. The install.bat stays in state "Step1 : Waiting for Device".
And im not sure how I passed the same flash recovery at step 3- I was stuck at the same step until, if i remember correcly, the script suddenly started copying files when the phone was already booted inside android.
How im trying to get it work:
The phone is disconnected from PC and turned off. I press VolumeUP and connect the phone to my PC.
Then the phone's led turns BLUE but nothing appears on the screen. And it stays in this state. The script doesnt recognise the phone and wont start copying. I tried connecting the phone with pressing VolumeDOWN- still no go. And I tried booting into the phone operating system and then connecting to PC- script still doesnt recognise.
what am i exacly doing wrong? thanks

my bad. had to switch to debugging mode and it went solid.
however i have not managed to get into recovery mode on my own. only after the script finishes and reboots- only then I am thrown to recovery mode. whats up with that? how can i boot into recovery myself? pressing the volumeup hasnt worked..
and another question. getting the phone back to stock condition (stock 4.2.2 ROM and stock recovery) I just need to flashtool the stock firmware on the phone?
sorry for dumb questions.

[Q] Chainfire caused reboot loop

Hi there i have rooted my phone with doomlord's latest rootkit for c6603 UK devices (you can tell im a noob), when installng and the opening he chainfire 3 app it asked me to install some graphics drivers and i did, it then restarted and then the loop restarted (turns off after sony logo, doesn't even get to xperia logo, then turns back on). I have tried several fastboot and flash methods but the problems still persists, does anyone know of any recovery or factory reset methods wihtout having access to your xz?
Thanks
1. Hold on boot volum up and power for 12 seconds i think.
Or
2. Charge the phone and see what's happening

charging it goes into a reboot loop then after a few times it displays battery meter...
ive tried flashing with flashtool but it comes up with "For flashtool, Unknown Sources and Debugging must be checked in phone settings", no idea how i gonna do that though, anyway to flash without this on? maybe fastboot?

I assumed you installed chainfire 3D app.
So, if you want to flash with flashtool, you must set your phone in flash mode.
Hold vol - when plugging the usb cable in (with phone powered off).
If you got the loop, plug the USB cable pressing vol - at the moment the phone is off.
And it may warn you about usb debugging, etc but just ignore it and continue anyway. Ive got back from bootloops with this regardless of unknown sources or debugging. Usually even when bootlooping the hard shutdown will work, hold power and volume up untill the phone vibrates three times and turns off. You may feel it vibrate once, ignore and keep holding.
You do need the correct adb drivers installed to use flashtool, the downloaf here at xda i believe includes them you just have to open the drivers folder, open the exe and choose your phone from the list. If you get into flashboot mode (when you hold volume up and plug it into the computer the led should flash once to let younknow its in the right state. Sometimes flashtool will take a long time to prepare the files for flashing amf your phone will start up... Let flashtool finish prepping, then it will come up with a screen telling you to put the phone in flashmode (usually giving the wrong instructions to do so, ignore them) if so, now go ahead and unplug your phone, power it down via the hard shutdown function i mentioned, then hold volume up and plug it back in. If you get the led flash its working, and if it wont then install its because your drivers arent installed properly.
Also i may be wrong, but the chainfire 3d drivers are for older versions of android, dont try to install them again. I did this on another phone that I had upgraded to jellybean and ot softbricked it. Jellybean runs ope GL fine on this phone.
Ive installed official frmware on my phone (through flashing) and now im about to root it again.
Thanks

I have kind of the same problem here, can you please tell me how you solved it?

Never seen this kind of brick before

So when I installed the TWRP app on the google play store and started it. It required me to rewrite my sd card or whatever so I went and ahead and did it. While my phone turned off still plugged into my computer via usb it started spamming the format windows on my computer. Like roughly 12 tabs opened up asking to format this drive. So I closed all the windows and re plugged in the usb and the same problem came up. And awhile all of this is going on the device is on but the screen is black and the back lights are on. Even when trying to restart the phone its the same problem stuck on black screen and the formatting windows keep popping up. It won't go to download or recovery mode it just stays on the black screen. This is my 2nd lg g2 I bought for business and I don't recall ever having this problem with my original LG G2. Anybody have any experience with this or a fix?

Yeah I've tried but the lg flash tool will give a error in the middle of flashing it
saying the phone is disconnected from pc, even though its still connected. It would go up to 25% then 60% then back to 25% in the middle of flashing then the error pops up.
Edit: Yeah while flashing the vs98024A kdz it will stop at 60% on the lg mobile support tool and it won't go past that. It'll just have the phone being disconnected from the computer error.
Is it safe to assume nobody knows how to fix this?
Same exact brick here.

Suggestion, have you tried the tot method yet? There isn't a 24A tot, but you can always take the ota.
same thing
I have the same thing and got it the same way with goomanager .was installing recovery and after reboot I got black screen with backlight on but to logo no nothing... can't get to download mode because I can't power off the phone. I also get the format drives promt in windows (about 15 or so all with a different drive letter) one drive I can read and it contains a folder called image with files in it. that drive is write protected. at this point I will wait till the backlight kills the battery and hope I can get into download mode after it shuts down.
FYI: I did try the LG mobile support tool but it did not see the phone. would love some ideas....

instead of waiting for the battery to drain, try this:
1. Unplug the phone from charger/USB cable
2. press and hold the power + volume down buttons for a few seconds... let go of the buttons 2 seconds after you feel it vibrate.
3. hold the volume up, and connect the phone to your computer.
you should be in Download mode by now....proceed to flash the phone back to stock using the LG Flash tool.
Hope this helps.
No Go

Xperia T - dead? No led blinking..

I was formating sd card in recovery mode, and then I chose "reboot to system" option, for leaving recovery. The telephone turn off. And nothing more. The battery was about 80%.
The telephone don't react on anything. No power button (or holding power button+volumeUp). If I connect usb charger, it doesn't do anything. If I connect PC via USB, there is no new device in PC. No led blinking.
I tried charging for hole day and night, but nothing changed.
I opened the case (it is just on screw) and disconnect and reconnect the battery. But nothing changed.
So I disconnect the battery again and connect usb. The red LED now blinks every second. And when I'm holding the power button, it doesn't do anything. But it is still the same.. black screen, turned off, no computer connection..
Have you any idea, what can I do? What can I try? Thx

You shouldn't have rebooted into system after wiping it in the first place, because you have no system now. You might try flashing any custom rom's kernel (boot.img) if your device is unlocked. You do it using Flashtool. First copy the boot.img from the rom's zip and paste it somewhere, then select the lightning bolt icon in flashtool, select fastboot mode. Then connect your phone to pc while holding volume + button and keep holding it until blue led lights up. Then in flashtool on the right side choose to flash kernel and select the boot.img you copied from the rom before. After that you should be able to boot into recovery and install any custom rom. If you do not have any custom rom on your phone, you can only transfer it from pc to your microSd card using the sd card adapter and then put the sd card back in your phone.
If your bootloader is NOT unlocked, then you can only try connecting your phone to pc while holding the volume - button until green led lights up. If it doesn't light up, I believe your phone is hard bricked and you can't do anything much. If it does light up, you can download any firmware for your phone in .ftf format and flash it using the same method as described above, but instead of choosing fastboot mode, you have to choose flashmode and select the .ftf you downloaded.

This. I was in the same situation like you just few hours ago. I decided to install custom stock based rom and I rebooted after factory reset. My phone wasn't turning on or anything, just dead brick. I left it for few hours and then I saw that red led was blinking while I was trying to turn it on. So I plugged it into my PC and it was charging (first success). I used flashtool and after many, and I mean it, errors it managed to flash my stock rom.
Now I am stuck at installing CWM v7 but that is another story ; )

HELP: Stuck on sony screen after installing ROM

edit: fixed it, just flashed a stock FTF, i'll dot the whole process again later on and hope this time it works out
You can close teh thread (i've tried to delete it but can't find the option)
I've just checked that I can boot my phone and recovery works. But for instance when i try to put service mode it gives an error with IMEI
edit: i've booted to the other recovery (using volume up) and installed the pre-rooted FW again. Shut down and tried again the flashmode process but still no luck, red and quick green light. After booting the phone, it seems to work basically, but wifi not working, it doesn't turn on.
What should the next step be?
The computer does not recognize the phone when my connect it to the USB port, not even charge. The only thing that happens is a flash of red light then green light. Same thing if phone is shut down when i connect the usb cable, red flash, then sony screen appears, then green light, and finally it vibrates two times before showing the level of battery, but without actually charging it.
Anf if i try a Vol Down+Power when in standby and connect with usb cable, it shows a quick red then green flash, and then nothing.
Ok i fixed that problem apparently the USB cable decided to stop working...
Now i have another problem as I decided to install the deodexed ROM and now my phone gets stuck at the sony screen and i can't even boot to recovery.
What i did to install:
Boot to recovery using Volume Up (PhilZ)
Prepare to install new rom (which formats Data, cache, etc)
Install ROM form SDcard1
Everything went fine but at the end it says "root lost or something" I put yes, then rebooted to system, and got stuck on sony screen....
What did i do wrong and how to fix it??
Thanks for the help!
