[Please help] Acer Liquid Jade won't boot, vibrates indefinitely
(01-07-2017, 01:08 PM)МиливојКовачевић Hi,
I have a Acer Liquid Jade S55. Tried flashing it using SP Flash Tool 5.1416.00 (which I have done couple of times earlier). After trying "Download only" option with excluding preloader tried to boot the phone but it stuck on Acer logo for more than 20 minutes. Turned off the phone, started SP Flash Tool once again and selected "Firmware upgrade" (as I saw it was suggested on xda-developers forum if "Download only" is not enough). After completing the process, I tried to boot the phone but the screen remains off and the phone keeps vibrating every 15-20 seconds. Tried flashing with different versions of firmware and SP Flash Tool after that (sometimes preloader only, than everything else), but it remains the same. Connecting to wall charger/laptop provokes same behavior (vibrating indefinitely). Not sure at the moment, but I think the battery level was relatively low when I first tried flashing process.
Does anyone know what can I do in order to fix this?
I've seen suggestions to keep phone on charger for couple of hours (or even days) until it displays it's charging but it keeps vibrating when I connect it on charger. Or even remove the battery and than start charging (which might not be possible as I think there is non-removable battery inside this phone).
(01-07-2017, 07:17 PM)МиливојКовачевић Already tried 3 different firmware versions. Kept it connected to my laptop overnight, but nothing's changed. I will leave it connected to wall charger until it gets enough power and hope for the best.
(07-07-2017, 01:12 PM)МиливојКовачевић Day six. Still connected to charger. Every once in a while trying to force charge by keeping power button pressed for couple of restart cycles (periodically vibrating), sometimes trying combination of volume up + power button, but still no changes. Not sure if it should remain on charger for some more time, or should I try to flash it with another firmware version and put it back on charger?

Stop charging it. Try another firmware if you can.
BTW, is the battery inbuilt or removable?
(08-07-2017, 11:39 AM)МиливојКовачевић It' not removable. Or at least not if I don't open it somehow, but the only screw which should be unscrewed to open it is somehow stuck.
So what's the best option to use now, if I'm going to flash it with SP Flash Tool again? Download only? Firmware upgrade? First preloader then everything else?
(10-07-2017, 03:45 PM)МиливојКовачевић Tried firmware upgrade with different versions of the tool and of the firmware. Most of the times I get "Failed to get PMT info." error:
Sometimes I get "Failed to open COM port.":
Tried 3 different USB ports, 3 different firmware versions and 3 different SP Flash Tool versions (5.1628, 5.1614, 5.1644).
I even got this error couple of times:
If I try "Download only" everything seams to go fine. Oh, and by the way, I keep external SD card inside the phone. Is this ok, or should I remove it?
And how would I boost the battery in case I manage to take it out?
