[HELP] Xperia ZL doesn't boot up, shut off when logo appear

[morizuki]

Good Day
Anyone can help me? I have a Sony Xperia ZL here and when I press the power button, it boot to sony logo then it shut off. Doing it again, it just shut off.

Tried repairing the device using Companion and it was successfully updated to the latest rom. But the problem still continues. It shut off as soon as the sony logo appear.

I Tried using the Flashtool and tried flashing lower rom. But still problem occur.

I tried using Companion again to update it but still nothing.

I believe you have a battery issue here. Need to change the battery. You can find one at aliexpress. I myself had the same problem. Changing the battery solved the problem. Youtube video for disassembling the Xperia ZL
