[Solution] Xperia T bootloop/won't charge below 0%

[RubenK]

Hi,

I've been struggling for a while to fix this problem. It's like this: phone gets below 0%, and won't charge. Only thing you can do is hold the power button while connecting the charger. It boots, but doesn't detect charging so it shut's down. After that it boots again because of holding the power button. The 24 hour charge trick also doesn't work.

Things you need:

1. Small philips head screwdriver.

2. High quality 2A charger.

Solution:
1. Open your Xperia T (use a small philips head screwdriver) by opening the SIM flap and remove the small screw.

2. Disconnect the battery flap.

3. Hold the power button.

4. Connect the battery flap.

5. Put the cable in your Xperia T.

6. Wait a few seconds.

7. Connect the charger to a socket.

8. Be patient.

Came across this by accident, has worked since with 2 devices.

KR,

RubenK

You forgot to mention that this will void the warranty, post the source link

Yes it works - It's called spoofing the kernel into thinking that enough power is their to begin charging - I wrote about this many many months ago and how the kernel works when charging

But as @uliwooly said this may and probably will void your warranty as you will have opened the device

That's right uliwooly, my bad! Hadn't thought about this, as this device is quiet old. Also, I just tried this, this afternoon, so I'm my own source. If that wasn't clear from my first post, it's because my English isn't that good, my apologies.

@Thommo

I didn't know that, couldn't find anything about it, hence my post :). Thanks for clarifying.

Hi Rubenk,

I've tried your solution on my xperia t. 

I'm not sure if I'm doing well:

I'm holdin the power button (3) trough 4-5-6-7 is it correct?

When I connect the charger to a socket my phone vibrate, once, 

now shoud I realease the power button?

Please help me do it right way!

Anyway my battery is really low, I think 0%.

I'm hoping you'll answer me, because I really would like to have back my phone!

Thank you in advance.
