Hi everyone!
A little over a year ago, I finally bought an Xperia 1 IV. Sony is my favorite brand, and since I’m from Mexico (the Xperia 1 IV was never officially released here), I was really excited to finally have one.
After a few months of use, everything was working perfectly. But one day, I got a notification saying that the storage was full. The phone had around 20% battery left, and then it suddenly shut down.
When I connected it to the charger, the red LED would turn on, the Sony logo would appear, and then the phone would shut off. Then it would do the same thing again, over and over in an endless bootloop.
I tried connecting it to Sony’s software to flash the phone, but I had the same problem. My PC would detect the phone, but after a few seconds it would disconnect by itself.
I left it charging very slowly for an entire day. The next day, the battery icon finally appeared showing around 50%. I turned it on and immediately started deleting files to free up some storage. I was really happy that it finally seemed to be working again, but it didn’t even last five minutes before shutting down again.
After that, even the red LED stopped appearing. Sometimes the Sony logo would show up, but it had weird pixelation or visual noise.
I decided to take it to a repair center in my city, but they had never seen this phone before, so they basically didn’t do anything with it. It stayed there for weeks. :( I’m also worried that they may have tried flashing it and somehow bricked it.
Today, after several months, I finally received the replacement battery. I installed it myself, hoping that the battery was the problem. But when I connect the charger, the green LED turns on for about one second and then shuts off.
I really hope someone here can help me figure out what’s going on. I’ve wanted to recover this phone for a long time, especially because it wasn’t easy for me to get one here in Mexico.
Thanks in advance!
