[Q] I9100G Bricked

Hello There
I Have a Galaxy S2 I9100G Bricked
The Phone Not Starting When It's Not Connected to Power Source .. When I Press On The Power Button Nothing Happen .. Just When It's Connected to Power Source (Charger or USB) it's Starting but Not Booting .. I Can See The Logo Then it's Enter Something Called #Manual Mode#
And Stuck There for 3 Sec and Restarts Again in The Same Way.
I Can't Enter The Recovery Mode or Download Mode or Anything ..
When I Connect it To The USB it Just Do The Same .. Odin Can't Detect it.
I Tried to Put it into The Download Mode While it's Connected to The Charger and The USB .. But This is Not Working.
As I Said Before #THE PHONE IS COMPLETELY DEAD WITHOUT ANY POWER SOURCE#
I Need Help
Have you tried using a USB Jig to enter Download Mode?
And how did it get bricked?

i have this exact model,
power off your device by long pressing your device for 10 seconds
just press vol down or up then insert usb cable
it'll bring you to recovery mode..
good luck!!!

Stuck in peculiar boot loop

I tried to flash twrp and now my phone is stuck in a 5 second boot loop.
Fastboot and recovery can't be accessed at all no matter what combination I make. vol+ power, vol- power, both +- power, hold 40 secs 60secs (useless because phone reboots in 5 secs) , all tried. Every 5 seconds it just boot loops. Help me.. I have it for less than a week. Wanted to flash only because the stock rom was giving problems such as landscape and auto random reboots.
I even tried a script which said would wait in adb detect mode, that didn't work. Guess phone rebooted before my pc could detect it. Tried installing intelSOC method as suggested in another thread, the short reboot is tough to get by.
By the way, it's an umidigi china phone.
bump.. pls help!
Hi , let your battery to completely empty , press vol + and plug usb to see if phone goes into Fastboot mode if not try Vol - and plug usb .
Both didn't work. But thanks.
