Xperia Miro doesn't start? Whats wrong?

Hi Folks,
a friend gave me an Xperia Miro. I sould change the glass.
So i tried to turn on before change: nothing happend.
I changed the glass, tried to turn on: Nothing
Xperia on the charger for 2 days: LED blinks steady red (about 1-2s between blinks).
So i thought it was the battery - bought a new one.
Battery loading: Battery gets warm (!?!) but still nothing happens.
Tried hard reset (vol up & power) LED turns blue steady (while connected to Powerplug)
As i plug off, the LED stopps. When trying to turn on: nothing happend.
Another few hours of Charging (always stock cable & loader): After turn on 3x red for 10s. Afterwards red 1x each 1-2s.
Tried to connect to PC & SPCC: No connection - phone not detectet.
Phone was never rooted or similar.
Is there any trick left? Is this a known issue? Warranty is over - he said it worked before screen change but he didn't use it for months.
Thanks,

[Q] Xperia E Total Hard Brick

I came across an Xperia E device for flashing. But its hard bricked I guess.
So far, I've tried to revive it all alternatives except for disassembling the handset.
1) Does not charge with any charger.
2) Have used different batteries.
3) Does not recognize in Flashmode or Fastboot mode
4) USB is not recognized at all.
The only hope that seems to come from this handset is,
Sensor light. This is 'not the Red Light' that comes while charging or powering on.
A small light deep in the sensor appears when doing the following actions:
1) Connecting charger with or without the battery, activates this sensor light.
2) With the battery, when I power it on, the sensor light appears till I release the power button.
3) When doing the power cycle reset option using the volume down or volume up with power button combinations, the sensor light stays till I release the power button.
So there seems no life, in this except for this faint red light in the sensor.
Any ideas?
By the way, this seems to have happened after a full reset including the internal storage using the factory settings reset option.
Device uses a custom rom.

Take Out the Battery!
Hold Volume Down!
Plug in Charger - MAKE SURE ITS FROM WALL SOCKET NOT PC!
YOU SHOULD BE IN FLASHMODE!

I got a Sony Xperia E C1505 (Rooting Status: Bootloader unlock allowed: No).
I have flashed it with free a firmware (C1505_11.3.A.2.33_CE.ftf) and made a backup of the TA partition.
Later the cellular is rebooted and does not boot again anymore, staying in a difficult state of hard bricked and the symptoms are same described by shaam_viru.
In general:
- Volume up down no response (obvious)
- Volume key down no response
- Any USB device (MTP, MSC, Flashmode) is not recognized
- The battery does not charge (wall socket was used not PC)
- Phone do not turn on with or without the battery and the adapter plugged
- Turned on with the battery or with the adapter, the device is limited to cast a faint and fuzzy flow of red light
Greetings.

same problem
I am currently facing this same problem on my device......IT happened as soon as i wiped my internal storage(factory reset including data deletion)....I was on a custom rom as well...The symptoms are the same as the first post.
If someone can help me i would be very grateful

Red flashing but cant turn on??

Hi, I have a Sony Experia Z3. Great phone Was loving it. However I woke up this morning To a frozen screen. The screen then went blank and I now can't seem to charge it or turn it on. I have tried all kinds of resets but nothing seems to work any ideas??
Please??

try this first -
a. plug your charger into a wall socket
b. connect your phone & leave it for a few minutes
c. hold the power button and the volume button down together for at least 1 minute
d. expect to see a red LED/no charge indicator
e. release both buttons
f. push volume up
g. expect to see an empty battery graphic onscreen
h. now press the power button and it should charge normally

Also try connecting via the magnetic charge port. That usually fixes mine when it won't turn on

Try a few hours charging (maybe a battery issue) and try turning it on or just exchange if that fails. A similar issue on my HTC One X was due to a motherboard failure, eventually it would not turn on at all and had to get mobo replaced.

Phone won't turn on

Hello guys, I have D6603 and tonight, phone gone dead... How it's happened... So, I was playing on phone and put phone in my pocket and stand up and phone felt from pocket and no reaction. I was thinking that display is broken.. but when try to make something, no reaction. I put it on charger (before drop it has 89% battery) and red light appear. I told WHY!? you have battery... after 10-15 sec, display light up and shows SONY, I told great, display is OK, but 1-2 sec after SONY logo, phone restart. NO VIBRATION, NO START UP, NOTHING.... when SONY logo disappear, red light gone for 5 sec, and then light up bright, after 10-15 sec red light dim and SONY logo appear, this is for 1 min and it stops, only red light... I left phone on charger, after about 30 minutes, red light turn off and nothing, phone won't turn on. I try Vol UP + power, yellow button, remove battery(when battery is not connect, it appear empty battery logo and 5 sec later phone restart, when connect battery again SONY logo for 2 sec and restart),nothing, no vibration... I try connect with PC, only fastboot work...

do the 20second reset. this simulates a battery pull.
i dropped my Z3 too, no damage at all, but it doesn't work at all anymore. No red lights nothing.

Is it bricked or just battery

So the Xperia z3 will not start and it seems that it doesn`t charge, furhther it wont turn on.
Tried VOL+\- + Power button and the little button behind the SIM-Cover - no reaction
When I connect it with a (working) charging unit the LED will light up red and the display shows a battery-symbol filled red on the bottom (10%)for a few seconds, then it turns off and shows the same things (led and screeen). Well it is some kind of loop. I charged it for over 24 hours with different charging devices (up to >2A)
When I connect it to a PC the LED is dark blue. PC Companion says that the phone is locked and I schould unlock it, which is impossible as I am not able to turn the device on
Connecting it to the PC while holding the VOl- the PC Companion can do a software-repair and it says it works, but it doesn`t change the behavior of the phone.

I once got hands on an old Z3 wich showed the same behavior, it was just the battery. I changed the battery and it is now working fine again.
