[Q] Bootloop after using LG Support Tool - GT540 updated to V20B
Sorry if the problem was written about before, but I've been looking through this forum and google for two days already and I've really run out of ideas. I had bought an used GT 540 from a friend and it worked remarkably well when I flashed it to SDSL 4.0
After having fun with learning the smartphone, since it was my first one, I decided to switch to it as my main phone.
First I wanted to take my simlock off, since it was locked to Orange (PL) and I'm in another network. I've read that it's possible to unlock phones only on stock ROMs, so I decided to use LG Support Tool for it (which I swear to never use again). It said that a new version is available and has flashed my phone to V20B.
Here the problems begin, because the boot is looping at the Android logo. The animation is playing for around half a minute, pauses for a half of a second, then the screen goes black and it appears again.
I've tried to flash the phone using KDZ_FW_UPD_EN and various ROMs in "download mode" by pressing vol - and power buttons.
The first few times it gave me an error:
13:55:00 : Smart : wParam = 100, lParam = 6
13:55:00 : Step : Upgrade Error error code =6
but for the past few times it seems to have completed successfully.
I don't know how to enter fastboot, it's possible that it's been removed along when I flashed the phone using the LG app.
I'm new to Android in general, what other info should I provide to help troubleshooting?
