Help brick bootloop (flashmode only 20''??) - Xperia Z Q&A, Help & Troubleshooting

Hello, yesterday I tried to flash this ROM: C6603_10.7.A.0.222_Customized MEA.ftt. I succeeded, although I relized I didn't wipe...so I (fool of me) flashed again, and here is when the trouble came.
Flash failed and since then I got the SONY screen and then a message saying: "the software update failed. make sure your phone is connected to the computer and try again" and then shut off itself. If I try to charge to the electricity socket it is when the loop comes in...this time no error screen, just sony and turns off and on sony screen offs, etc...
I thought of flashing again, but the problem here is when the device won't stand in flashmode more than 15-20 seconds and then the red light led turns off (as if the device had been disconnected) and therefore flashing is impossible (it starts correctly but when the red light turns off a error message "31 : A device attached to the system is not functioning" appears, as if I unplugged the phone...)
I also tried to restore with pc companion but the problem of the short flashmode still goes on. What can I do????why the device turns off (or it seems that) after connecting to the pc??
Curiously, I can get to fastboot mode (when connected to the pc, if I push UP button led light turn blue and keep it until I unplug, contrarily to what happens with the flahsmode)
The model is unlocked bootloader, but it is not rooted and I could not install recovery, so wiping through it is dismissed...
Is it possible to flash from fastboot (since in flashmode is impossible?)
I also tried a hard reset by pushing + and - buttons while starting, and 3 vibres happen and it tuns off but the problem still continue...
PLEASE HELPPPPPP

[Q] Boot loop with purple LED??

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

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!

Hard Bricked Xperia TL?

Ok so im dealing with a possible Hard Bricked Xperia TL, unlocked sim (not sure about bootloader)
well it started out as so.
one night the phone was supposed to be charging but it was not. The charger was extremely hot and sometimes the phone would be as well. The battery went 100% dead and from what i heard is that i should NEVER let it get that way.
so then i tried to charge the phone but all that would happen was that the red power led would flash and go away. and if i press the power button it would flash 2 times and not boot. no matter what happened i could not the phone to charge. then i tried to do the "rubberband trick" Placing the rubberband over the bower button and trying to let it charge while plugged into the wall with another charger. and it would stay on a steady red light for a bout 10 or so minutes and then stop.( rumor is that it wont charge that way without a sim card in the slot but i dont know about that, Plus the customer didn't leave the sims card.
anyway so i assumed that the phone needed to be reflashed with flashtool so i downloaded the correct FTF and attempted to flash the phone. I was able to get to both flash mode and fastboot mode at the time. But whenever i started flashing the rom after about 10 minutes allmost at the end of the process while it was flashing the system partition it would report a error
ERROR - Read error :31 : A device attached to the system is not functioning.
ERROR - Error flashing. Aborted

i tried many times to do this.
about 2 times i got the sony logo to flash for 1 second then back to not responding...
now after trying some more its even more unresponsive. I cant even get to any modes. no flashmode or fastboot.
and when i plug in the charger the power led flashes once and does nothing else even if i hold any or all buttons while plugging in the charger.
and when i plug it in to my computer the computer makes the noise that a usb device is plugged in.
in device manager the phone pops up as
"QHSUSB_DLOAD" with a triangle prompting that The drivers for this device are not installed.
anything i can do?
EDIT: QHSUSB_DLOAD drivers are installed and read by S1 tool but another error occurs.
Anyone?

flashing issue (help)

hello,
have a c5303 xperia sp and im trying to re-flash the stock rom using flashtool64. the phone doesnt power on but if i hold vol up/down then plug the phone into my pc via usb the respective fastboot/flash mode led colour lights up and it pops up on my computer to confirm it. when i try flash the stock rom, is gives me a error about system.sin, since then i am not able to get into flash/fastboot modes on my phone. as this has happened before (the phone not going into fastboot) im pretty sure i can get it to flash without system.sin then use fastboot to do it after.
the screen is completely blank, not even a backlight. when the usb is plugged in without a mode, it is red on the phones led, when i unplug it and try to turn it on, the red led flashes and nothing happens.
thanks in advance!
fixed it nvm
