So, my jxd s7800b now has a broken USB port.  I used it exactly 8 times before it broke.  I was extremely careful when plugging and unplugging the cord as the orientation on a new device always takes some getting used to.

I can no longer mount it to my PC, so no more rkbtools for me.  Also confirmed USB otg no longer works so it's definitely the port..

I just hope all the updates I need to do from here on out can be done from the recovery ROM....

Oh well, no point to this, just posting my frustration.  Not going to bother trying to send it back to dinodirect as I'm sure the return shipping would be outrageous and I know "wear and tear" generally isn't covered.

I received a damaged unit with R1 and R2 broken and that won't charge. I'd recommend opening a RMA case with Dino. If you paid for the insurance at checkout like I did than I think they will reimburse you for shipping. I'm waiting for them to authorize the shipping costs. I will keep you posted.

The assumption is made due to:
1. JXD advertising the device as 1.6 GHz.
2. RockChip advertising the chip as stable up to 2 GHz.
3. The fact that every time the device boots with the original firmware, it tries to reach 1.6 GHz and fails.
All this leads us to believe that the second batch is the broken one.
Also, you're correct. On most devices, EMULATION wouldn't suffer a huge hit, with the exception being PPSSPP due to it not being optimized for multicore. But, higher end Android device already do suffer a hit, which will be compounded by the fact the SoC has a lower maximum frequency.

Also, when the S7800B was first released, there were many problems due to the faulty recharger JXD supplied. This is still true, but people have published workarounds and willgoo has supplied replacements - so you hear less and less about it. Also, the light leakage was so easily solved it shouldn't even be an issue, merely an oversight (it's loosening 4 screws that were overtightened).
The most notable issues were the faulty touchscreen and controls on JoeSixPack's unit, a unit with a missing back camera, and a unit that was fried due to the charger. 3 units out of thousands shipped. Crashes were rare, and I don't remember hearing about one.
So yeah. The S7800B's launch wasn't perfect (add it to the 2 month delay), but I'd rather have a light leaking device with a faulty charger than one with voltage leaks - at least I can take care of the first one.

Joe, I do have experience in soldering but it's just your basic stuff.  A couple mod chips, and other large and brainless points where I end up making 5 cold solder joints before fixing them.

My unit runs at 1.4, but I didn't pay for the insurance that I can remember.

Honestly, I can live without usb IF all the updates can be done from the recovery screen.  If they are going to require rkbtools then I'll have to whip out the soldering iron and try not to make it worse.

I have no intentions of using a 3g dongle or Bluetooth devices via otg, and all file transfers are done with my card reader anyways.

Thanks Joe

I actually just checked and I have a 99? return package fee on my invoice.  I'll have to check with customer service to see if that will do it.  My only problem with returning it is the is of getting one with bad buttons, touchscreen, or one that doesn't charge at all.

Of all the things that could be broken, the USB port is probably the least in inconvenient.  I already use ES and I agree, it's awesome. 

I know the SD card updates were killed, but if it's anything like my phone the updates can just be done from recovery boot by selecting install from zip file.

I'm just too much of a chicken to try it, brick it, and be SOL with no way to recover.

I took my unit apart, the usb port had the middle part with the pins get pushed right out the back of it.

It's just kind of press fit together, I tried putting it back but it still didn't work. 

So I decided not to press my luck and put it all back together.  3 of the little plastic clips that hold the back on pretty much disintegrated and fell off

Lol, what a giant POS this thing is.  It runs great, but my god the build quality is garbage.  I even used a spudger that I've used numerous times when repairing cell phones and never had this issue.

The USB port on my unit appears to have sunk a little into the console. I shaved some plastic off the end of the cord where the USB jack is and it worked, sporadically.
