[Q] VERY UNUSUAL SITUATION. Xperia Miro

First of all, sorry if thread is in a wrong place.
I have very unusual problem with Sony Xperia Miro, as for now no one could help me.
My friend had this phone first.
He said it started crashing randomly, then ram dump happened. He found some new phone so he left Miro in a drawer for few months (this might be somewhat important). After that time he gave it to me. Now it doesn't even turn on, when I charge it Led Light doesn't even flash red/orange/green (Note: it flashed red for a brief moment once), when I plug it into PC, computer can't, see the device,though Flashtool detects it, but can't interact with it.
Battery was checked with electric meter and it says it's charged half full, so it should work.
So basically phone is dead, but its unlikely a physical condition since it's in great condition and also it happened with Software issues.
If anyone had a slightest idea what could it be, please help.

Low battery bootloop but accessible via PC (fastboot & flashmode)

Hey community,
i bought a sony xperia z3 three months ago.
Yesterday I recognized that my phone was at 50% battery after charging the whole night.
I thought that its a bug or something and I got my real 100%, but after ~3 hours it was still at 50% and suddenly there was the "you have to charge your phone"-pop up for 1ms.
So i decided to plug in my charger and thought my phone will charge again. But no, the battery icon also switched from 14% to 50% in this 1ms. It was going on like (13%<->50%, 12%<->50% and so on) this until my phone died and got 0%.
I haven't unlocked my bootloader, flashed it or something like this. It was the original vodafone branded sony xperia z3.
Until now I can't charge my phone, because everytime I plug in the charger, my phone is booting with the low-battery icon and after 5 seconds it's turning of in a loop. Booting for 5 seconds and then shutting down and so on...
I thought my phone will have enough battery when I will plug in the charger for the whole night and my phone will try to start in this loop until it has enough battery. But again, nope!
Now I decided to unlock the bootloader and flash my phone with Cyanogenmod 12 or CMW, because my phone is accessible from the computer. I can go into the flashboot and flash mode.
But also after unlocking and flashing I've got the same thing again. It won't start.
I tried to charge it for about 4 hours in flashboot mode, because then the blue light is shining and my phone is not shutting down. But NOPE, same **** again.
I don't know what I can do anymore. Can you help me?
Do you think I have to change the battery?
Looking forward to hear from you! It's only three months old never dropped or something like this.
greetings and sorry for the wall of text

bro warranty covers that, but as soon as u unlocked bootloader, u kinda voided that too =(
go to Vodafone and DO NOT mention that you unlocked bootloader and explain the problem within 2 weeks of purchase u should receive a brand new device and afterwards they'll repair it for you
I have a small crack (2mm thick and I think it came from pressure) at the backcover and asked vodafone if they can change my backcover, because now it's not guaranteed that it's waterproof.
They said no, because it's my own fault if something is cracked or broken on the case and I have to pay 259€ to get a new one.
Yesterday I called vodafone again because of this problem and they won't repair it, because of my first support case and I have to pay 259€ to get a new phone. I was arguing for about 1 hours that this is a guarantee case and it has nothing to do with the crack, but they don't care and there are some laws that I could say that they have damaged my phone and so on. No chance.. Maybe I should call my advocate.
I read something about locking the bootloader? Maybe I can flash a stock version and lock the bootloader?
Try yellow reset button.
I also tried this before. It doesn't fix the problem.
Hi guys, Sorry to bring up such a old post but having a similar issue.. My Mrs phone just started rebooting one day, Vodafone refused to replace because tiny crack. The boot loader is unlockable I tried repairing with xperia windows tools the flashed older and different firmware's many times. The phone works when connected to PC but when unplugged or on normal charger just constant reboot.
Any suggestions on what to do?
Thanks

[Q] XPERIA ZL C6502 Problem turning on

HI Everyone,
This is my first thread. Recently came across xdadevelopers forum. I am using Sony Xperia ZL C6502 for about 2.5 years now. Few days ago, when I was using the camera app, it crashed and shut off unexpectedly. Then when i tried turning it on , it keeps switching off after the point where it says 'SONY XPERIA' (generally within 3-5 seconds). Firstly , I was able to switch it on properly while on the charging mode and work with it when battery is charged upto 70 % and more. But the problem got severe and now even when I charge it, it keep repeating this loop of switching on and switching off at ' SONY XPERIA' as mentioned above forcing me to open the battery switch from inside and switch it off or by pushing it into either flashmode or fastboot mode. Even this restarting process consumes alot of battery and battery level dips very fast without any heating or so. I only manage to switch it on properly sometimes by means of charging the battery upto the level and then switching on and using it while still charging ( this works one in the fifty times). I have tried flashing new lollipop version and even tried repairing thru PC companion. No Progress. Went to service centre , they said it is some boot supply issue and battery and boot supply needed to be replaced . I am doubtful as of now if I either use it solely on charger or battery or if i use it on both.. the problem is same.
Is it a battery issue or a corrupt bootloader or something not in my knowledge. I have tried this flashtool. Suggest me what should I do now . Final alternative will be to shed money to the service centre. PLEASE HELP

Xperia Z3 won't turn on, no light

I know there is a lot of post and solution of the "sudden death" for the Z3 but none of them has worked for me so far. I've tried anything (except opening the phone), pressed any buttons for any given time but the phone won't turn on. Even the light doesn't turn on. I also bought a Sony dock to charge it hoping that the micro USB port was broken but even after letting it in charge for a night, nothing happens.
I've also done all the steps from the Sony official website even installing the Xperia Companion but obviously it doesn't detect the phone...
Is there anyone that can help here ?
Thanks
How did you solve the problem?
My phone is still dead. I'm not able to turn it on. I just replaced the old battery with a new one without improvement .... :/

Sony XZ Premium Green Led stays on

Hello there
Today i finally wanted to start my sony xz premium again after having trouble getting it charging, possible usb c port damaged.
I got it charging for 20 minutes and was going to check how much it charged
When I saw the phone I noticed the green LED was on so I assumed it was fully Charged.
After trying to start it up I didnt do anything no vibration no Sony screen.
After reading how to force reboot it I tried that and it wont do anything.
Before I try a hard reset I wanted to ask if someone had the same problem or any idea how to get it running again?
(Currently it is in a salt/Rice bath cause im assuming liquid inside)
Update after letting it in the salt/Rice both for 2 hours the green Light dissapeared
But now everytime I try to Charge it,it stays on the charging picture but without any prozentuale showing.
After 5 min it will try to start but keeps getting stuck at the Sony Logo.
I got it charging with an 0% Indicator so probably will let it in the salt/Rice bath longer
