I rooted my z1s today, then i installed recovery then flashed the rom for our phone made by tactic, all was well but everytime i booted the phone it always said android is upgrading, then it went through all the apps, so i thought why don't i just wipe system cache data and dalvik, then install the rom again, big mistake at first it booted to the sony logo got stuck, i kept turning it off then on 3 times, then after that i just went into flash mode with the led turning blue, after that i turned it off to save battery because i didn't download the ftf and flashtool yet, so after all that is downloaded i try to go into that mode again by plugging it into my computer then volume up and power but then it shows a red led for a brief second then stays black screen, not on ithink. When plugged into my computer it shows usb device not recognized so the phone is still alive. so my question is, what can i do to save my phone? pleeease help :crying: and yes i kind of literally cried

You wiped the system and then wonder why there is no system?
Just repair your phone using pccompanion to get back to stock
Or
Flash a Z1S FTF using flashtool.
Then, spend some reading the threads and learning what to do before blindly flashing and wiping stuff.

Have you tried using them yet?
In your last post you say you have not even downloaded flashtool yet?
Download it, run driver.exe from the driver folder in the installation path. Choose flashmode, fastboot and Z1 drivers
then run flashtool and attach the phone with it turned on.
Detach the phone
Attach the phone again in flashmode.
Please post the log from flashtool here

My phone doesn't even shutoff, no vibrations etc, just the computer saying device not recognized, and the phone was unplugged while trying to turn it off
flash tool also says device disconnected? and i can't upload the log file
Press and hold the power and volume up until it vibrates 3 times. Then it is off.
Just copy and paste the window from flashtool here.

Press and hold both of them at the same time

Blue LED means fastboot, for flashmode you need a green LED
Press volume down for flashmode and volume up for fastboot.

HEHEHEH what helped me was telling me to hold the vol up and power for a minutes, i went further to like almost two minutes and after that i started stabbing the red button next to the sim card with a toothpick LOL
So I did a stupid thing and didn't do my homework. I flashed CM 10.2 for Xperia T (Mint) on my rooted Xperia TL but didn't unlock the bootloader first. The phone won't boot. Just a black screen. If I hold the power button, it vibrates once, but nothing comes up on the screen. No LED light indicating charging while plugged in.
Have I just destroyed the phone?

No. A custom kernel won't work on a locked bootloader, so that is essentially your problem. Just put your phone in flash mode and use flashtool to flash a stock FTF and it should boot up just fine.

Then maybe put your phone in fastboot mode and flash the kernel first... IDK, I did that once and I'm pretty sure that's how I fixed it. With 7zip you can extract the "kernel.sin" file from the FTF, and use Flashtool in Fastboot mode to flash that kernel.
Thanks. I've been trying to put it into fastboot and can't get it to work. From what I have read, I need to hold power+volDown, right? I've held power + volUp to get it to vibrate three times, then connected it with the power & volDown buttons held and nothing - no blue light for fastboot mode. I've currently got it plugged in (using the oem Sony cable) with a rubber band around the power & volDown buttons. Maybe that'll work... I dunno. The led is just staying red, and I can't see it listed as a fastboot devices by typing "fastboot devcies" when cmd is open in the correct folder in the sdk... Any ideas on how to get this done?
Thanks for your help, everyone.

It's a bit hard to understand what you're trying to do
Fastboot mode = just press vol.up, keep on pressing, connect USB, when you get a blue light release the vol. button
Flash mode = just press vol.down, keep on pressing, connect USB when Flashtool is ready to flash the FTF, when you get a green light release the vol. button
As you can see, you don't have to press the PWR button (only pwr + vol.up to reset, but you already know it).
Usually it's enough to flash a new FTF... I don't know why you get that error: maybe a wrong button combination or maybe you didn't install the drivers needed for flashtool.
If your battery is almost discharged, the fastboot method is good to flash only the kernel in order to recharge the battery and then flash an entire FTF.
I guess your device is ok.
Anyway, have you already seen this guide?
I'll give it a shot. I can't seem to get it into flash mode or fastboot mode, though. When I hold down the Volume up or volume down button and try to plug it in, the light stays red and the computer makes a "connect" sound (Windows 7 - rising tones), then multiple "disconnect" sounds (falling tones). The light stays red and the phone is not connected.
I'm downloading a stock firmware and flashtool and will report back when I've tried it some more.

I suggest removing the battery, if you have the chance.
Keep the battery removed and press and hold power and volume up buttons simultaneously. Then plug the phone to your computer and you'll enter fastboot mode.
I revived my XV with the same red led that way.
Had to remove the battery before it would work, tho.
Good luck bro!
Sorry it took so long to get to this. I've just been using my backup in the meantime.
I took the battery out and plugged it in like you suggested. Worked like a charm! I've got it flashed and running now. Thanks!
Flashtool does not recognize my device
I can't access Fastboot or Flashmode.
When I press the power button nothing happens.
When I plug the phone into my computer or a wall outlet and hold the UP volume button the LED flashes red then turns blue. It stays blue.
When I plug the phone into my computer or a wall outlet and hold the DOWN volume button the LED flashes red then green then the LED turns off.
Any help is greatly appreciated.

When I get to step 6 nothing happens. it's like I can't get into Flashmode. It just repeats connect your device. No matter how many times I do it or how long I hold the button. It's not recognizing the device. PC companion doesnt recognize it either.

Yes. I broke the charger connector thing in the phone. I had it repaired and it was working. I honestly think the place that repaired it messed with the phone to get more money out of me.
They fixed it and when I took it, once it ran out of battery it started to do the same thing again. I cant figure out what it is.

VOL UP (Blue LED) is fastboot. This is working . Thats a good thing.
1. Turn the Handy off
2. Press and hold VOL+UP
3. Connect the cable
4. Wait till the LED is blue and take your fingers from the phone
The display will indicates nothing in this mode.. It's normal.
Now you can Download TWRP Recovery for C6603.
Have you got an open bootloader.
which rom you wanted to install? stock? custom?
1. Download the boot-twrp-v2.img from (please take the right version for your phone):
http://forum.xda-developers.com/xpe...t/recovery-stable-twrp-2-4-3-0-touch-t21821122. Make your PC available for adb+fastboot:
http://www.android.gs/install-android-sdk-adb-windows/
&
http://www.chip.de/downloads/Minimal-ADB-and-Fastboot_62500183.html3. Go in folder with "fastboot.exe"
4. Press "Shift+Mouse-Right-Click"
5. "open command windows here"
6. C:\Flashtool\adb>fastboot.exe flash boot boot-twrp-v2.img
Go in Recovery and wipe/factory reset (or flash a new rom, ...)
Should work. Good Luck.
you could try to recover your os via Sony PC Companion

your solution is not going to help because its a hardware problem and pc companion wont help since the phone wont even boot up
in a similar (or worse) problem :
was just using the phone when it hangs .. Instead being smart and patient, I tried to hard-reset it .. the screen goes dark, my android wear disconnect .. but then I literally got nothing ..
tried to put it to the cradle, connect the USB to computer, no lights, nothing
fastboot mode : volume up + connect USB, no lights, nothing
hold power button : no lights, nothing ..
the phone feels cold, so the procs seems to be sleeping ...
any ideas ?

believe me hard reset didnt do that. Either your battery died and now you need a new battery or you phone died and now you need a new phone
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
I was flashing my phone and half way through my computer lost power. Now the phone does not start. I can't get it into fastboot, or flash mode.
Pressing 'vol up' + 'power' doesn't work either. Anyone knows how to repair a hard brick?

At least you could say the support that your device turned of while applying a firmware update and that they need to give you a new device :silly:
