Reviving JXD S7300b from 'Deep Brick' State

[gogorman]

I tried on my other older Windows 7 system. Still no dice.
I don't have it with me right now but I'm pretty sure the red light comes on when I connect to both the power and PC.
Tried with Vol - and Power yes and just connecting to the PC (which turns green light on when connected.)
Any ideas?
Does the fact that both the green and red lights come on mean there is some salvation for me yet?

I thought so, as some others have mentioned that if the charging LED came on it was just the 'hard brick', but I never had any luck with connecting to ANY PC to try the USB upgrade.

I returned mine to the seller I purchased from on Amazon and they are going to ship me another one.....

I'm running win7 English, flash ends at 75% - device manager shows world cup device up to final commands at 75%, then is disappears. Relevant output from usb burning tool below

[T 5][10:35:16]: command exec:bootm 0x82000000
[T 5][10:35:18]: boot uImage ...
[T 5][10:37:14]: cannot find disk! 100times
[T 5][10:37:15]: failed because no connected device ,current step is 18

Not sure where to progress from here, I also tried this on a win xp machine same results. Any help would be appreciated.

hi, I also lived the experience of my jxd s7300b brick, follow the steps for pins 5 and 6 with the only difference that when connecting the usb to pc, press volume +
and I recognized the device, windows 7 32bit

Holy crap! I think it's going to work... My PC did notice my device as world cup device and now im just gonna download a new firmware from jxd official site.. hopefully it brings 7300 alive again!

I bought JXD7800B 16GB for 6 months ago and bricked it after trying to upgrade the unit because it was so laggy.
I was close to throw it away and found this fix.
It was deep bricked and after the steps "nomad83" wrote it worked and I managed to get it to work.

JXD´s latest firmware package 4.4.4 and Rockchip 1.7 in Windows 7 64-bit OS.

As I look at the picture (very small when not member) there you short the circuted, I got two on my JXD.
I short pin 8 and 9 from the left on both "chip".

Good luck everyone, hope it works.
Thank you Nomand83!!
