Bootloop and battery won't charge - Xperia Z2 Q&A, Help & Troubleshooting

so i was flashing existenz MM and i can't go to recovery mode, before installing it i have xzdual recovery installed, so i thought i can just flash it again (and ofc it was stupid because after that i just know xzdual won't work with MM) so it's bootloop even when i charge it, the problem is the battery died and it won't fill the battery, the phone keep restarting when plugged in with charger so it keeps draining the battery before it filled up, i can't flash it because of that, the question is, how can i fill the battery so that i can flash it using flashtool?
thanks, and sorry if my English is bad.

If there is no other way you can always open the phone and charge the battery manually(if you have the equipment to do that). I had to do that to my phone yesterday(my battery was so low that it wouldn't boot).

You have to use a hairdryer. There are tutorials on YouTube.

The phone should also be able to charge in recovery. Try that.
Btw. I recently flashed a Z2 via flashtool with an unplugged battery (usb power was enough), so you could also try flashing it now although it's empty.

Thank you for the reply,
but the phone cant boot to recovery.
so i should remove the battery and try to flash it without battery plugged in?
because i tried to charge the phone overnight with no luck, havent tried removing the case yet because im not experienced to remove them, is there any alternative that i should try without touching the hardware stuff?

I would first try to flash just like it is now, without opening the back cover.
Opening the back panel is the last option I would consider, but only if everything else fails.
The thing with opening back cover is, that you will most likely damage you back panel, and you will have to order some new, fake raplecement + the phone won't be waterproof anymore.
And if you can get your phone into fastboot mode (and you've got unlocked bootloader) then just use "adb fastboot flash boot boot.img" command to flash some kernel with recovery.

Have you tryied to plug it in and then press power and volume up continiusly until you fell three vibrations? i think this is for reseting the phone if you continue to press until another vibration it will shut down and maybe then it will charge.

i tried the vol up + power only one time until it vibrates 3 times for the first time and its off, but when i plugged the charger its continues on bootloop cycles thus battery not filling up.
i guess im gonna try until another vibration and see what happen.
and thank you for the link, im gonna give it a try too later, im not home right now, cheers.

It won't probably charge in fastboot/flashmode.
But it's very strange that the PC won't detect your phone when trying to enter flashmode.
Because, as I said earlier, I was able to get Z2 into flashmode without any power (battery taken out).
There should be some change in device manager when you connect the device.
Are you sure all the drivers are installed on your PC?

[Q]Can't boot xperia x10 mini pro in flash mode and can't back it to stock ROM

Hello comrades,
I have xperia x10 mini pro. I rooted phone with Flashtool and installed CWM. I tried to boot it in flash mode (turned off phone, back button held and plugged in USB into the phone), but what I get is that my phone turned on always, like that I pressed Power button.
Earlier I couldn't boot it into the flash mode and I got that I charging battery, but after I installed CWM, phone always turns on.
Due to, I can't re-flash it because it always turns on. I tried with flashtool, PC companion, SEUS but all software need that I turn off phone and then hold back button and plug in usb and what I get is turned on phone. Please help me how to fix this problem.
I would like to re-flash it to stock 2.1.1.A.0.6 (2.1-update1).
Phone turns on even if I just plug in usb to phone (one end is in the PC and when I plug in other end into the phone, phone turns on). What is wrong guys?

Leave your phone plugged in and press POWER-HOME and BACK all together, as soon as the screen turns completelly black (backlight off too) releast POWER and HOME, and leave the back-button pressed, that will probably work too.

How do you mean until I reach connection step, where should I reach connection step?
You take out the battery, then you go into PC Companion and follow the steps to repair your phone, until it asks to connect your phone in flash-mode.
Then do as he said (put the battery in etc.)

What do you think, what will happened if I wipe it using CWM? Can I brick it on that way?
If you mean formatting your phone, so you don't have a system on there anymore... that probably will give you a brick. Flashmode is a hardware feature, implemented to install firmware and enable reparations to your phone's software.
Deleting everything you can will not magically solve your problem, as far as i know.
It might help if you get mad at the phone and abuse the back-button by repeatedly pressing it when connecting the phone.

Does this mean that I have hardware problem. Phone works without any problem.
Somehow it doesn't detect you pressing the back-button, maybe there is some dust or dirt inbetween the contacts or something, since you flashed sucessfully before i don't think it's a serious hardware-problem.

I didn't flashed it before, I couldn't do that. I couldn't unlock bootloader, because I couldn't boot it in flash mode (phone just show that battery charging), after installing CWM now phone even don't show that battery is charging (it turns on when I plug in USB in the phone without holding any button). This is nightmare!
You are still on the original firmware then?
I mean, your phone still works?

Yes, I am on original firmware and phone still works, but I have problem to boot it in flash mode. When I plug in USB cable in the phone it turns on, like that I pressed POWER button. I don't press any button, but when I plug in usb cable 10-20 seconds and phone is on.
Yes, because your phone detects the usb-cable getting plugged in, even when it's off, it thinks you want to charge it, so (normally) it loads the kernel in order to start the charging-process, that is normal behaviour. I have been on a kernel that didn't support that feature, and it booted into the full rom before it started charging.
In short: the usb-port also functions as a power-button, sort off
Does the back-button work normally when you're on the firmware? (Like, open the app-drawer, pressing back-button should close it?)

Yes, the back button works perfect, closing apps (not close apps, but back to the phones "desktop"), back to previous pages in browser...
I am concerned because, before I installed CWM , when it was OFF and plugged in on USB, phone just showed black screen and when I clicked on some button I could see that battery is charging, that was all. Now, when I plug in USB it turns on like I pressed POWER button.
And off course never booted in flash mode because it turns on

What is app-drawer, I don't know what is that.
oh, that's the bit where you find all your installed apps, the grid you see when you press on the little triangle on the bottom of your desktop, or swipe up on the desktop.
I honestly don't know why your phone won't go into flash-mode though. Maybe try to take out your battery for about 10 minutes so your phone gets rid of all charge and static, and then try again.

I solved problem about POWER-ing on when I plug in USB. I installed new ROM "MiniCM7Pro_V21_Paul_XXX" via CWM because I didn't need to boot it in flash mode and now when I plug in USB I got that it charging battery and orange led diode.
But I can't boot it in flash mode even with new ROM, all the time orange led diode when I hold back button and plug in USB. I wiped out all date except something about "battery" from Advanced CWM options.

Phone wont boot. Bad flash

Xperia S Issues. Bad Flash
Hi, I read the 'existing users' installation instructions on the Sspeed ICS rom and installed the rom without installing the ics rom and kernel (I was tired). When booting, I go in a bootloop with the doomkernel screen. I can access recovery fine.
When holding vol+ and connecting to PC the phone goes back into it's bootloop and does not boot into fastboot.
When holding vol- and connecting to PC the phone flashes the green led and then boots into bootloop.
If I wait until the phone vibrates and lights up blue I can press the button to access recovery. I thought I could then just copy a gb rom over using USB mount but it is not detected on the PC.
Any help would be greatly appreciated.
Thank you

im not the expert here but I have bricked other phones before but never an xperia phone before. I have been reading up, the doom kernel has some mounting options, try to mount the sd card as mass storage so pc can send files accross to the phone. It should be mount and storage menu -> mount usb storage, then leave it on that menu and connect to computer, see if that works

If it blinks the LED for a second and reboots, that means that you don't have the drivers. Install drivers that are bundled with flashtool and try again. Or use Linux / OSX.

Just Press VolUp and Power button until you get (one vibration followed by 3 consecutive vibrations) ... it will mean phone is shutdown.
Once shutted down, you will be able to press VolDown while plugging phone to PC and it will enter into flashmode.
Then you will be able to flash a FTF using flashtool
doesn't work...after the 3 beeps i let go and the screen turns black but then the boot loop happens again, i cant turn the phone off

Hello. I've got familiar problem. My phone blacked out after one day having about 35 % battery full. I was trying to reset it by holding power and volume up buttons - nothing happened. Just once showed up Sony logo but then again black nothing. Then it vibrate 3 times quickly and from that time it is shutted down, won't turn on even in flashmode. LED is not working too. I was asking for advice in local store servise and guy told me, that new phones have to be at least 30 min on the charger. So it's here now for hour, no result. :/
Just fixed this issue.
Follow these steps
1.hold vol up + power until phone vibrates 3 times.
2.open flash tool and point towards your stock file.
3.hit okay
4.wait for flash tool to prepare the files then it will prompt you to connect device in flash mode( vol down + power)
5.wait for it to finish. Unplug reboot and there you go fixed...
Hope this helps

Use the bundled wallcharger!!! not a PC, pc has too less power to charge it now!
After wallcharger is placed hold vol+ and power for a few seconds until 3 vibrations, then let the phone on charger for atleast 2 hours, if all is good phone will bootup to the "charging animation"

Something similar happened to me. I have the bugged version of chargemon (only can charge with phone on) and accidentally discharged completely. The phone didn't boot, didn't charge and didn't do the 3 vibrations thing. So I put the battery off, conected the wall charger, putted the battery and it booted
It's really easy to remove the battery, you just need to be careful

[Q] [U] Not turning on after installing kernel. Bricked?

Hi guys, yesterday I unlocked and rooted my Xperia U, as I didnt have time anymore, I decided to install the kernel today, so when I installed it, I tried turning on my phone - nothing. I just got that red light thingy sometimes that is active 2-3 seconds, I tried charging but still nothing, funny thing is, when I connect it to my 2nd PC with XP on it, it connects, but in My Computer I only see "Digital Camera" and cant open it, also Windows Explorer popup for it keeps constantly, well, popping up but its empty and I cant select anything. I'm now downloading flashtool, is there anything I can do else? Im desperate, I got this phone for only 3 days.
Okay, now I'm in flashtool, I'm about to start flashing but I cant get into fastboot mode... What should I do?
Bump? :crying:
Please dont make me spam, I searched everything, I'm pretty sure my problem is unique, I cant access fastboot. Nothing
try this:
1. charge your phone for about 1 hour
2. open flashtool then click fastmode and choose your firmware.
3. make sure your phone is off ( i dont know if this is the same with xperia U volume up+power button wait til vibrates three times)
4. when it says connect your phone into fastmode, connect your phone via usb, then hold volume up + power button and wait till it vibrates three times, then hold power button+ volume down.
5. it will flash your firmware.
or you can flash the stock kernel (just extract from ftf, same instructions above).
I charged it for the whole night, the problem is, I cant access fastboot. All the drivers are installed but nothing.
I'm sending my phone for repair probably, with rooting I broke my warrant, what's going to happen?

Not vibrating, also, no led.
The only sign I get is when I take out the battery and put it back in, it vibrates for a second. Thats it.
Try to remove the battery and than try all keys combination,and also try to get to connect it to your flashtool.Try hard reset combination.Remove the battery,put the battery,hold power+vol. up button for. 20 sec. If that doesn't make.Try the same only with vol. down button .If that doesn't work,take it to the service shop than....
Hit Thaks if I helped
Hold vol up when replacing the battery, then quickly shove the USB cable in. Phone should vibrate when you put the battery in and you have a second or two to get it into fastboot or flashboot.
Probably a bad install of a kernel, make sure you're using the right one for your phone.
Not sure if it works for the U, but that's how I fixed my Sola.

Xperia P wont boot and if cable is plugged and it doesnt even charge

Hello to all!!!
I have a problem with my XPERIA P(not rooted or unlocked), it wont boot if the cable is on the phone(pc or wall charger) and doesent even charge. When tryong to boot it shows only the SONY logo, not even xperia(which comes right after sony).
Tried getting into flash mode or fastboot mode, but it is the same thing.
If i switch on my phone with no cable plugged it starts normally.
When this happened i had no battery at all. After searching the web i found a guide to open my phone and remove the battery connector. After removing it and plugging back again it started charging. Now it wont charge anymore that way.
EDIT: Mac wont recognize it anymore(mac bridge, flashtool, adb)
Does anyone have an idea?
Thanks!

Try flashing the phone with stock ftf file via flash tool , you can find plenty of how to videos for that on internet . Your phone will be fine I guess
Search "Your phone model " "version" "stock ftf" download and flash it
Hit thanks if helped

The problem is my phone wont stay in flash mode. It shows up the green led just for a sec and then tries too boot up normaly(green led turns red and shows sony logo) then it shuts down again...
Same for fastboot mode (blue led for 1 sec then again red).
Any idea?
Thanx in advance
@aserreqi
The disconnection issue is driver related. Use windows 7/xp (friends computer) install flashtool and then install the driver pack located in it. Then flash stock ftf.
Before this charge your phone overnight.

I tried with windows 7(sus, flashtool, pc companion) and osx (sony bridge for mac and flashtool) with no results.
I will try again with windows if can get to charge it any more, because now it is not giving any sign of life
Thanx

I had similar kind of issue , phones doesnt stay in flash mode when it should but I managed to get into fastboot mode , IT DID STAY THERE for me and I flashed some other kernel to make it work for few mins as I only wanted flashmode to work which it did . Try charging your phone for 2 hours and grab any kernel which is said to be fine with your phone , either ways you only need flashmode to work. If fastboot is also disconecting even after you have charged your phone umm DRIVERS DRIVERS !
Make sure you have all the drivers installed I always use flashtool, nothing else to flash

I have charged my phone now for 3 hours. The only way i get to charge now is discharging the battery to 0. I have to put it on charge(wall charger) pull off the connector of the battery and then put it again on.
If the phone is a little charged and i turn it on it wont charge any more. No charger or pc works.
I tried again the procedure of getting into fastboot or flash mode, but still nothing happens.
Green or blue led for a sec then tries to boot again.
I forgot to mention that the phone works like normal when not in charge, it boots normally and everything works fine...
P.S. the drivers are installed. I installed them again and again.
Thanx for your help anyway!!

Good luck ,btw I dint understand PHONE WORKS NORMAL WHEN NOT IN CHARGE ? how is that possible

I hope u didnt fry your phone charging ic like i did on mine. Using fake charger and short hv burst suddenly turn my phone exactly like yours. I somehow managed to recover from it temporarily by shorting usb wire while charging it and eventually the phone die. Haha lol.

This is not the same problem.
First try volume up + power for about 15 seconds untill you feel (1+) 3 vibrations to turn it off.
Then try flashmode.

Z2 bricked and can not turn on

Hello, guys
I upgraded my z2 from 5.1.1 to MM. It's existenz v1.0.0. It worked good. I wanted to downgrade to Lollipop 5.1.1 . I entered TWRP and restored the ROM that I saved before. I press "reboot system" and then It totally backed out. It can not turn on. I pressed power + volume up, it didn't vibrate. I tried, tried... many times but it didn't work. I use the flashtool to downgrade. When I pluged the cable and pressed volume down. The red light just flashed, flashed and flashed and nothing happened. What is that problem. Can I save my phone anymore. Plz help.
Sudden death.

Have you tried pushing the red button for 5 seconds under the microusb cover flap to completely reset the system?
Does the device get recognised in the DeviceManager, if so have you installed the correct developer.sonymobile[com]/downloads/drivers/xperia-z2-driver/ drivers for it? (you could also try it on ubuntu)
Are you sure your connection / cable is good?
Have you tried to boot into theandroidsoul[com]/sony-xperia-z2-flash-mode-54084 flashmode? (volume down), does it get recognised then?

I tried the ways you showed me. Sadly, it didn't work. The cable I use is OEM. I connected it in flashmode to flash. It didn't recognize. The red light of the phone kept flashing. Maybe, my phone is completely dead. Thank you for helping me.

Ah, this doesn't sound too good. The good thing is that the flashtool works, but since it doesn't help you may try a method called "test point". But if you decide to do it, be very careful not to touch anything else with the paper clip (if you touch the small component with the metal surface there will be sparks coming out).

My phone is LB. The battery was about 60% plus at the time of restoring the LP Rom. I pluged it in to charge, but the red light kept flashing.
