I have a very strange problem with my Xperia LT30p. It has been a while it is not shown in computer when I connect with USB neither it charges from computer. Interestingly phone has no problem with UTG. It works perfectly. It does one peculiar thing with wall charger. It doesn't always charge with wall charger. After few minute of connecting with wall charger, it charges sometime. But when phone is switched off, and connected to wall charger, it immediately showing SONY logo, led is on for about a second or more then it restarts, shows SONY logo and charge it normally. After this, if phone is turn on, it continues charging with no issue. This happens with other computer charger/data cable (tried samsung, HTC, nokia & sony)
After this problem has arise, battery drains very fast. Battery goes from 100% to 50% in 6-7 hours without touching it for a second with all background apps frozen with Greenify. Previously it only went around 85-90%. I tried volume UP+power on, didn't help. Then I tired Factory data reset from setting>backup&reset>factory data reset. Now after factory data reset, phone no longer is rooted and battery drains more faster. I can't do clean installation of OS from Sony Update Service as it is not detected at all in computer whether phone is turn on or off. Neither it is shown in device manger in computer in unknown device.
Firware version?
Rooted?
Custom Rom?
Unlocked Bootloader?
Custom Kernel?
What did you do just prior to this problem starting?

Hi,
So... After flashing 4.2.2 everything was going great since this Monday... i spotted that my battery level was changing like a freak (on Excelsus 4.2) and whenever i wanted to plug in my charger to phone it didn't show the charging icon, but on phone turned off it showed but level wasn't rising... So i wanted to flash system backup, but then i got softbrick... I couldn't even get to recovery anymore, so next day i flashed .253 but it didn't change anything. I tried also to flash .423 again but it also nothing changed. And today, after recording some video, phone went dead, so i thought that i'll be able to charge it, but no. Whenever i want to turn on phone, it vibrates and nothing more happens, when i plug it to the charger, the red led light lights, sony logo appears, phone turns off and it loops... Any solutions? I can barely flash anything thru flashtool, but it also does nothing. Will I be able to send it as warranty repair or it may be voided? (i unlocked bootloader, but now it's locked)
I attach a screenie from yesterday, where you can see that battery level went insane and in addition it didn't want to go higher than 58-60%
Regards and thanks in advance,
Bairei
Have you tried anything from this thread?

Somehow I've managed to boot my phone. But the weirdest part is, that it had only 7% battery while the system launched. Now it's charging and hope it won't have any difficulties with charging or battery level.

Now the battery level is changing like insane, and phone doesn't seem to charge... While i was removing the bloatware via Root Explorer, the phone turned off, and when i turned it on, the battery level was changing, like earlier...
Plus, the led light while charging phone on or off doesn't light, also when i connect it to usb (but it works, when i launch phone)...
Hi guys,
I am having some problems. Last light, my phone ran out. I charged it, and when I woke up this morning, it won't start up. Every time I plug it into the charger, it gives a RED LED light at the top. Every time I pull it out of the charger, the RED LED disappears. It is running a pre-rooted version of Android KitKat 4.4, so I guess that means it has lost warranty...
I have not tried plugging it into a PC yet.
Please help, thanks.
Sounds like it's bricked. Can you get into flashmode when plugged into pc?

No, it couldn't be recognized by any programs (SONY PC COMPANION, Flashtool etc)
Very weird: a minute ago, it was charging, wouldn't boot up, still red led like before etc... And I didn't realize my laptop was on low battery and ran out, and my phone stopped charging. And the phone started up automatically after that? It had 3% battery, so it was not charging.
The battery keeps going from 3 percent to 4 and back.

The phone will not be recognized when off, when off keep pushing volume up and connect via USB to PC, it will be recognized in Flashmode and flash a new FTF 4.4 from Flashtool.
If it turned on then leave the phone under charge (Wall Charger) for at last 4 hours and check again, if it still give you problems then I will recommend to do a Factory Reset or flash a new KK and wipe everything, Data, Appslog and Cache.
Hi everyone!
A few minutes before, I was using my phone and it just turn off... Black screen and I have to turn it on again with the power botton. For the moment I think that was an issue with the firmware that I recently flashed over flashtools, is the last unbranded firmware of USA and it was working excelent.
The thing is that I pluged it to the PC with USB to download a photos and my computer didnt realise that the phone was pluged. I try every USB port of the PC and no one works. Also, the phone dont turn on the charging led.
I plug it to the wall with the USB charger and nothing... The battery was over 48% and suddenly it turns off... Then the screen shows me the battery image with 16% and it dont charge anything... It was working fine over my desktop, until that happened. I didnt drop it never, I never used an other charger, allways the original.
PD: Now the battery image says 15% (the phone is pluged to the wall)
Edit: I Just turn on the phone to make a fast backup and the battery says "17%"
Edit2: The magnetic cable charges the phone.... Randomly restarts. One time it just freezes and the speker emit a little "biiiiiiiiiiiiiiiiiiiiiiiiiiiiiiip" and just auto-restart. I think that is big hardware problem... Or something else that I didnt know:crying:
What was the status of your phone in terms of locked / unlocked, recovery, ROM etc.? Can you still get to flash mode?

Hey man, the phone had a Retail Spain firmware. The only thing I "put hand" was flashing with Xperia Flashtool to the last United States firmware available. Not rooted, bootloader unlock allowed but I didnt unlocked it. You can say is "original".
The phone charges normally with a Magnetic cable (same original charger for the USB cable).
When the battery rise over 50%, when you turn off the screen, the phone autoreboot. With the scree ON you can use the phone perfectly.
I charged to 100% with magnetic cable. I turned it off. Then, a 2 o 3 days later, I dissambled it thinking that water could get inside, but I dont found anything, all the components were in perfect conditions.
After I re-ensabled it, the phone dont turn on and the screen show the low battery icon... So I plugged it to the wall with USB, the red light turned on, and after a 30 minutes it stop "charging", so I put the magnetic cable and the battery after a little more than an hour and half more, rise to 100%... Now the phone not reboot it self, it works perfectly except the USB port.
No starting Flashmode, no chargin via USB unless the battery is COMPLETLY empty, then it charges to 1% and continues with magnetic cable. The PC dont even knows when I plug the phone.
I know, I lose the warranty when I open the phone, but I bought it at 10.000 km away from my town. :crying:
Hi everybody,
I upgraded my Xperia Z to Lollipop. Immediately after that I got the following problem in the order described:
- Phone was at 80% after upgrade.
- It was not charging after the upgrade, and I had no more connection to the phone via USB anymore. Also PC Companion did not see the phone anymore.
- The battery drained after some time so the phone went into "brick-mode" because connecting it to the pc via USB, nor connecting it to (different) wall chargers did not charged the battery.
- With the phone compeletely empty, I just left it connected one evening to my wall charger, and when I woke up the next day the phone was again completely charged to 100%.
- But no the circle starts from the front again --> no connection to PC and not able to charge the phone until it goes out completely, waiting for some hours connected to the charger, and only then it starts charging again until 100%. I also once booted the phone before it was at 100%,.. even then it will not go on to charge when the phone is on, NOR will it continue to charge when I shut it down again manually (so not let it drain to 0%).
Does anybody had/has the same issue? I think it is a waste not trying to fix this because the phone is still in a very good condition.
Any advise would be helpful, thanks, Pieter.
I REALLY need help
Sometimes when i plug the charger into my Xperia z, it instantly shuts off and boots on
A week ago, i plugged it in, it restarted and i went to lunch.
When i came back, i couldnt turn the Phone on, i literally tried EVERYTGING (every buttom combination possible), the LED didnt turn on and the Phone didnt respond to anything.
Just completely dead.
I charged it for 3 h and because the LED didnt even turn on while charging, i thought the battery might be broken.
So i removed the backcover, unplugged the battery and plugged in the charger.
There was finally a sign of hope when the LED turnt red, but as soon as i plugged the battery in again (with the charging cable still in) the LED turnt off.
So i ordered a new battery, put it in and charged it for 2h, still the exact same issue.
If anyone has a clue of whats the issue or experienced it himself, please help me.
Phone specs:
Rooted, bootloader unlocked, custom dual recovery with twrp and philz recovery installed, stock rom with android 5.0.1, about 2.5 years old, perfectly functioning until this issue occured
