Root Motion Hard Bricked Jig Test

OK I know everyone said this wouldnt work, and for the most part it didnt. I tested my jig running 900 ohms capacitors and nada. Just to make sure it wasnt faulty wiring I tested it on my Galaxy Rush and boom download mode. Now is it just not enough power, cause my dads an electrical engineer and he said doubling the ohms would be safe, though would it be enough or is there another reason, and if so why, does a power jolt throw a Samsung into download mode, but wont throw an LG into download mode. Its not like a HTC goin to bootloader, are they really so different

I think when you hardbrick, you break download mode.
 
I wanted to mention this but sin,ce his dad us an electrical engineer i became confused.
I have no clue a jig works. The capacitor stores electricity then releases it to cause dl mode?
Or he meant resistors and then would want to reduce the resistance to increase the voltage?

I think resistors are used.
 
So somewhere on the board a voltage spike causes download mode.
Doubling the resistance would lower the voltage spike not increase it.
l have a feeling that the post was not worded properly

umm.. Capacitors aren't measured in Ohms, Those would be resistors..

Capacitors are rated in Voltage, and (micro/pico)Farads...

good point, my dad was asking capacitance and resistance( i didn't know what he was talking about) and he said bring me what you got and ill set it up. Dad isnt much of a tell you what you did wrong kinda person, so I never learned what I was doin,and Im pretty sure he used a part I didnt bring him. He just said try this and see if it works
 
or.... your dad knew exactly what he was doing and it doesnt work on lg devices.

it seemed to work just fine on your rush...
 
It could be the wrong resistance. I read somewhere thats its 135k ohms for lg, but i cant find the link right now.

did a quick search and keep finding the same 3 values listed for LG phones. 56K, 130K, and 910K ohms. Im thinking that its the 130k, but what do i know.
