when you connect your phone in flashmode green light should stay on (press & hold vol down then plug usb in)
it should show
"device connected in flashmode"
IF you want fastboot mode
when you connect your phone in fastboot mode blue light should stay on (press & hold vol up then plug usb in)
NOTE-it should actually do bootloops....not sure why red light

Sometimes flash tool, while flashing tells me to turn on usb debugging (although its already on). So what do I do? Wait. After ten minutes(approx), device disconnects automatically and then flashtool requests me to connect in flash mode. So I disconect my usb cable and connect it again in flash mode and voila! flash begins. Worked for me, hope it works for u too..

yes thats a common mistake
on flashmode connect phone in flashmode only when asked (or like you said ...you will have to do twice)
on fastboot mode your phone has to be connected in fastboot before selecting the fastboot mode

I'm having very similar trouble, i flashed FXP CM10 a little while ago until the phone stopped receiving a signal (which has happened a few times using CM10), unfortunately the battery died before i got home to flash it again. 3 days and 7 hours later and the battery still hasn't charged, i've managed to boot into android very quickly while it's connected to a wall charger but i get nothing at all if i try and connect in flashmode or fastboot.
Is the battery dead? Is there something i'm probably missing? I figured this might go to someway with hoping the OP.
[Edit: Good news! I've plugged into USB and i can get to the battery bar with the power symbol, maybe i can get to flashmode after all!]
[Edit 2:] Noticing the phone had just enough power to get to the battery/power symbol screen, held down the volume button for about a minute till it went through that cycle and managed to get it into flashmode, installed stock and plugged it into the wall. 5 mins later i hit the power button and it's working again! Hooray!

use jim34 cm10 with hsr0 kernel....FXP IS CRAP for daily use

don't connect your phone to the pc until flashtool asks you to. I get that thing sometimes when I reflash a rom or kernel

Miro bricked after flashing wrong bootloader

Hi,
I don't know what can I do now, perhaps noting. I accidentialy flashed wrong bootloader (from other xperia, not Miro). Now phone seems to be completly bricked, I can't turn it on and my PC does not see any new device after connecting phone to usb. I also tried to remove and insert battery, after this when trying to power on, there is short vibration and nothing more.
Do you have any ideas? Or I simply should to use it as brick, not as phone or put it to my toilet and wash? Thanks.

Can you get in flashmode? Power button down + connect to pc. Flash proper ftf for your phone.

Don't worry, Your phone is not hard bricked. As you mentioned that on starting , phone is vibrating that means there are chances to recover your phone.
1.First go through this guide :Using Flashtool for Xperia devices
2.Download your current stock firmware . Visit this: Miro all official firmwares
3.Install proper drivers as mentioned in the above 1.flashtool guide.
4.Flash the firmware for your phone , according to the above 1. Flastool guide.
5.Wait untill flashing completes. start your device when you are told to do so.
Good luck :good:

It seems I can't. I already tried this, but nothing happens. As far as I know, there should be blue led after connect. But nothing happens and PC can't see any new device.

You should see green light. Try this :
Pull out battery, hold power button for 10 seconds without battery. Reinstall battery, hold volume button - and connect to usb. Then follow steps that prateek.invasion gave you.
The point is you can flash ftf and restore your phone.
Good luck.

Thanks, I will try. Batteery is not charging, so I need to do this quick, it was not fully charged.

Unfortunatly, I can't do anything. I tried to connect while Volume down + power pressed. But nothing happens, only led flashing with red color. PC can't see any new device after I connect to usb.
Any ideas?

I had the same issue with my xperia e after I unlocked the bootloader and installed CWM, the phone just rebooted itself at boot up. If you have installed CWM I suggest you to install a custom rom and a new kernel. That worked for me . Or ofc, if you have warranty you can send it to them. They won't be able to tell if you installed another rom since the pc doesn't recognize the phone.

I don't have cwm... trying to connect to computer with volume down pressed. After this led starts flashing red and computer can't see any device connected
Seems there is no any recovery or I can't put it to recovery mode.

D2303 Xperia can't boot after unblocking bootloader

Hello,
I just unlocked the bootloader of my Sony Xperia M2 (following the instructions on the Sony website).
I installed Flashtool and I followed the Sony instructions. In the end, I got a message in my terminal saying that the process was completed successfully.
After that, I tried to turn on my phone, he vibrated but the screen remained black and did not turn on.
I tried to reconnect to my computer by holding the Volume + button to enter the fastboot mode, but the LED does not light either, and I do not know what to do ...
If anyone could help me that would be really great because I'm a bit annoyed that my smartphone couldn't boot ...
Thank you!

Try reflashing the stock rom FTF (recovery mode : power + vol down while pluggin the USB)

Thanks, I solved my problem yesterday night by flashing a stock rom via flashtool and everything worked fine.

Stuck in bootloop after a failed flash

I already had a Cyanogen ROM on my Xperia Z5 and was browsing the forum here and saw a Paranoid android ROM so I wanted to try that. I had CWM recovery on it, went into recovery and wiped the necessary parts. Then flashed the rom zip and the gapps. After that I rebooted but the phone kept shutting down and only blinking a red light.
So I connected it to my computer and put it in Flash mode, used Flashtool to put it back to stock. While stock was being flashed on it and halfway it gave an error (which I don't remember) and the phone booted. I assumed it was correct, it gave the white screen with the 'Sony'. After that came a black screen with the 'update failed, please connect to a computer'.
This screen is on for half a second. Then the screen turns off and the same process begins with the sony and then error. This keeps looping when charging or connected to a computer. The Xperia Companion doesn't help and I can't get it in flash mode of fastboot. It is hardbricked and what should I do?
If you need more information I'd be happy to provide it asap.
Edit: It's the same problem with as this thread only the solutions provided won't work

Did you try to turn off phone and press and hold power and volume up butto to see is the phond vibrate 4 times after few seconds.
Second,try older version of Flashtool and unpack the firmware via Flashtool to see if exist file named fw.info If exist delete him and creste Ftf sgain.Flashing via flashtool would not succed if this file exist ,so i repeat to delete him and try again.

Thanks for the reply and helping me find a way out!
However, when the phone is off and I hold the power button and volume up noting happens at all. This combination only works if I want to shut the phone down.
And I don't think the problem is within the firmware but within the device, because you have to enter flash mode to use Flashtool and the phone won't enter flash mode (or fastboot) anymore. I can't flash anything atm.

No luck here on xda or anywhere on the internet. So I'm sending it to sony hoping they can fix it....

Xperia Z5 E6683 dual - Boot looping

Hi all,
i have been attempting to root my Z5 dual, i have unlocked the bootloader no issues.
but when i got to the stage of trying to flash TWRP.img thats where i ran into issues, it flashed ok - but now my phone won't boot - it is just stuck on the white sony screen.
the only way to turn it off is to hard reset ( hold power button and the volume buttons until it vibrates 3 times ) - then it will power on if i hold down the volume key and press the power button - or plug it into a wall charger..
when it does turn on it gets to the sony screen - the LED goes white, then amber for a second or two then the LED turns off..
im not too sure what to do now guys - my laptop wont pick up my device any more so it seems as though i have soft bricked it. i have also tried the P.c companion thing also but it says i have modded software so it can't do it lol.
help me pls

Hi,
If you already have installed the z5 drivers on you laptop (i assume this is the case because pc companion is installed and detect your phone), guess you can try to flash a stock Rom of your contry using flastool, your laptop will normally detect your z5 cause you connect it thanks to a special manipulation (vol - + connexion while button is maintained) .
Try this if everything goes great, it will fix the bootloop issue.

I got the same prob and eveb worse (battery 0% and wasnt charging) i hard rest it ( vol up+ power) and left it for 10 seconds then i pluged into my laptop while holding vol down and suprisly my laptop detected my phone and i was saved ! But i was scared about the flashig procsess as my battery was 0% lol

thanks for your response,
my phone is no longer being recognized by my laptop - i have tried a bunch of things - it doesn't boot loop any more - if i turn it on ( well attempt to) it will just show a no battery picture - out of 20 times of trying to get it into fast boot mode it the green LED will flash for a second or so and then it will turn off again.
i have tried to leave my phone on charge for a whole weekend to see if it worked - but it still shows that it has no battery

You dont need put your phone in fastboot mode than flashmode.

flashmode not fastboot mode . make sure u install flashtool drivers and fastboot drivers and ur devices drivers as well. dont skip this just cause u think u did it. if you are on a windows pc windows 8 - windows 10 , you have to disable signature verification in order to install the drivers. if you dont know about that , tell me to explain . apart from that , what commmand did you use to flash twrp? fastboot flash boot twrp.img or fastboot flash recovery twrp.img? if you did the first , thats why it doesnt boot. and apart from that , can you at least enter the recovery ?
