My phone, Acer Liquid Z630s, recently had a problem and ended up shutting off as soon as it boots up. I turn it on, the Acer powered by Android white screen shows up then immediately shuts off. What was the problem here?
I couldn't access recovery mode either because it would also show up the same thing above then shut off immediately before it can even reach the recovery mode menu. But I could plug it in directly into download mode through SP Flash Tools because the phone vibrates when I hold down the volume up + power buttons (aka the recovery mode combination which was I think also the download mode combination). I downloaded the correct stock ROM off the Acer website (MT6753) and flashed it. The ROM was successfully flashed. But when I turned it on the screen lit up but it was just a blank black screen. It was lit up, but it was just dark black. I tried to wipe the system and flash the ROM again and at the end of the process, an error message appeared and I looked up the error code and this was exactly it:
Message: BROM ERROR: S_SECURITY_SECURE_USB_DL_DA_RETURN_INVALID_TYPE (6104), MSP ERROR CODE : 0X00
Meaning: Wrong flash settings or firmware
Ensure you set the correct Download-Agent in SP flash tool and are using a firmware for your exact model
Go to Options > Option > Connection > USB Speed > Full Speed
Go to Options > Option > Download > Untick DA DL All with Checksum"
I did what the solution told me, and as I tried to flash the ROM again, but I couldn't turn on my phone anymore. The volume up + power button combination no longer produces a vibration, and when I plug it into my computer it gets detected as a MediaTek USB Port (COM6) but SP Flash Tools no longer detects my phone and gives off this error:
Message: S_DL_GET_DRAM_SETTING_FAIL (0x13BE)
Meaning: The firmware you're trying to flash is either not compatible with your device or you have selected the wrong flashing settings
Ensure that the file(s) you're trying to flash are actually for your exact phone model
Ensure you tick the boxes for only the files present in the ROM you're about to flash"
I don't know what to do at this point. Is it beyond salvation? But my phone still gets detected by my computer and it still produces the sound when you connect a device through the USB ports. Help me please.
Thank you in advance.
