Can't charge xperia Z2 and Bootloop - Xperia Z2 Q&A, Help & Troubleshooting

So my phone slowly died this week.
It started to randomly shut off and back on again, and than i could use it for about a couple of hours before it rebooted itself again. But the random reboots started happening more and more. And now i'm at a point where the phone wont turn on anymore...
the battery is drained, and when i plug it in to charge it tries to boot into android(and not the battery/charging screen). but it has to little power to actually boot up so it shuts down before the sony logo is even gone. i don't have recovery becuase it got deleted for some reason. (that is where this problem started). But i can however put the phone in fastboot mode. but it wont charge in fastboot. Is there any way to charge the battery without the phone turning on or someting?

Boot your phone into flash mode and restore stock fw using flashtool by androxyde. Afterall your phone should back to life.

[Q] P500 turning off after severals seconds. Weird image.

I put my phone at charging last night when it was turned off.
This morning, I saw the screen was on, but black.
I tried pressing some buttons, nothing happened, I pulled out the battery and pulled it in again.
Turned the phone on... the LG logo screen appears, after around 3-4 seconds, it's some kind of blink(0.5-1 seconds) and the LG logo appears again. After another 2-3 seconds, some kind of battery appears that is charging on the screen and then the phone turns off. Tried 2-3 times and same thing. (Note: Phone wasn't charging! The charger was removed)
What to do.....? My ROM is AOKP.
Things I tried:
Charging the phone without battery(reboots again and again)
Pulled out the sd card and pulled in again.
Tried to boot into recovery but no success.
When connecting to PC, the phone is detected, but detection dissapears when phone closes(explained above)
> If you already tried all of those, then recover using kdz updater, flash the stock rom, root back, and flash recovery again.. well.. lets wait for more replies might help you out.
what phone mode should I select?
CS_emergency, diag or Emergency?
My phone screen is right now black(it's turned off but screen is black)

This is one old problem. Whenever it happens.. just boot into recovery and REBOOT from there!!
This is happening to me and I can boot by getting into recovery, however I need to sell my phone and worried it will be classed as faulty,any idea how to fix properly.
Already tried the delete data etc

[Q] Dna battery or motherboard problem?

Hello guys I want your help a little bit
I have a Droid DNA and suddenly the phone has turned off for no reason, when I turned it on again, it frezees in HTC boot logo "blablabla development blablabla) and restarts and it keeps in a bootloop, I can enter into fastboot, so I put it on to charge it, and 15 minutes LATER, i tried to turn it on again, no luck, so i put it into usb mode, and booted and it can boot normally, but when I quit the usb the phone turn it off and goes again in this crazy bootloop, also I cannot enter into the recovery mode (I installed TWRP and tried to enter but it freezes into in blue logo), and again I put USB on (No charger) and it enters, I flash a ROM and reboot, but when I disconnect USB CORD (NOT CHARGER) it turn off and again comes the bootloop crap, so I think its the battery but I opened the phone and I dont see a sign of battery death (like inflated) so I dont know if its a battery problem or a motherboard problem? What should I do? buy the battery or have a nice red brick? help me please.
Sorry for bad english Im not American.

Help! Xperia Z Ultra without OS and unable to charge it.

I accidently wiped off my system with cache and others with twrp, I was going to flash another ROM with it but i ended up on the SONY screen and now I'm unable to get into recovery itself and the sad part is that phone was on very low charge at that moment and it has drained now, even if it charges a bit it shows up at that SONY logo with no signs of further charging.
I want to charge it so that i can enter flashmode or fastboot mode so that I can atleast flash it with a ROM.
Really disturbed without OS and can't even do anything to it.
Please HELP! or tell about any charging signs or something.
Thanks

why not turn phone off and let it charge then? you can force phone to shutdown by pressing/holding power + vol up button for 30sec
If it does not charge (it happened to me once on my ultra) I understand your concern.
Here is how I over came the issue, i downloaded flashtool and a flashable rom.
Start flashtool, chose to flash device, flashmode, open your rom, in the exclude section, exclude all but the first line, plug in your phone in flash mode, flash line 1, remove your phone, keep flashtool open, stick the phone it on the charger for 10mins (this seems to give it a very small charge, enough for a minute flashing) do the same with each line of the rom.
I will not say this is going to work, but it has worked for me.
At one point (after the 5th line or so) it just starts accepting a charge then you can finish the whole rom.

Boot loop caused by defective/dead battery

Lately, I've been working with Lenovo A6000 to recover it from hard brick. The weird things are that I've tried Lenovo Downloader, Qfil, fastboot method but to no avail. Trying to boot into recovery using fastboot but only stuck at boot screen. At first, I don't think that the battery is the cause but I tried switching battery with other phone and it miraculously boot normally. The phone with the battery now suffer bootloop. As a conclusion ;
+Dead battery cause phone to bootloop, so try to change battery first.
+Recovery can only booted in if there is at least 30%
Am I right? I need to be clear about this thing.
Also can you all suggest some signs of dead battery?
Sign of defective/dead battery
+Charge 'ridiculously' fast when charged through offed phone

Oneplus X not booting or charging

So I have a OnePlus X with AOSP 9.0 installed. I tried to root it using SuperSu and when I tried to reboot it after the process was done, my phone got stuck in a boot loop. The OP logo would come on the screen for a second, the phone would vibrate and then automatically go away repeatedly. I was unable to access the recovery and was only able to get the phone into fastboot mode which told me that phone has a locked bootloader.
I feel like I might have accidently corrupted the partition that has the phone's BIOS or something
Eventually my phone ran out of battery and now I can't even charge it to be able to get into fasboot mode again. I have tried leaving the phone plugged in for two days but it isn't charging. It keeps going through this cycle of charging for a second and then not charging and wasting power for 3 seconds and leads to no gain in charge.
I also have a video of the charging boot loop if someone needs to see it.
PLEASE HELP ME :crying::crying::crying:
