Hello, new here!
Always been stalking around here, decided to finally give in and ask for some help.
(edit; I think this should be relocated to the troubleshooting section, sorry!)
Long story short, I received this tablet because it was broken and no longer turned on.
Ordered a new mainboard and it was still dead.
The battery will not charge with the new mainboard, but will with the old one.
A charged battery will not turn on the old mainboard, but will with the new one.
Here is how I am currently charging it:

"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
The old board is lying ontop of a plastic bag that is ontop of the new board.
Only the battery connector and USB are attached to the old one.
As you can see, it is drawing about 0.41A.
After a while of charging via the old board, I hookup the new board again.
It works, but it slowly drains back down to zero even while plugged in.
It only draws 0.07A in that state.
I tried a new battery as well, but that didn't help.
I have no idea what could be wrong with it, besides getting another dud mainboard.
About ready to give up, but I have invested so much time into this, it would be a shame to do that.
Any ideas about the mystery of why it isn't charging at any descent rate with the new board?
I have tried countless different chargers, the cable and connectors seem fine.
Shameless bump?

Phone out of warranty a month ago.. now cable only works when tilted left, moving right results in disconnect and stopping of charge.
So...

Found this, but 10x of them is too many, and $40 is too much.
Anyone know where I can get just one usb port, and how hard it is to install?? Does it require soldering? (I can do it but I'm not very good!) or does it just slot in or something?

The layout of the pins almost looks like it's a plug and play sorta thing.. or maybe they solder onto motherboard, idk, anyone got a tear down manual or service manual of the Optimus 2X?
Thanks.. Or if you had the same issue and found a fix for it please post that too I've tried cleaning with a toothbrush.
Edit: Tried that cable on my Nexus 7 and it did the same thing! might not have to repair phone, ill update when I find another cable.
Ok this happened when I unplugged the cable..
PHONE IS FINE, disregard lol.
I looked on ebay.com for usb port optimus 2x and find this http://www.ebay.com/itm/New-USB-Cha...675?pt=LH_DefaultDomain_0&hash=item3f1a465583 just 3USD :/ or this one http://www.ebay.com/itm/Replacement...083950?pt=PDA_Accessories&hash=item5d3475a5ee its from USA so I think it will arrive faster.
I found the cable that came with the optimus 2x box kinda tight,you need to pull quite hard to unplug the cable from the charging port,
to avoid damaging my optimus 2x charging port
I use my sony ericsson x10 mini's charger cable instead, much better and smooth unplug :good:
Charging my SGS becomes impossible now after 4 years. Although ist shows the charging symbol, my device doesn't charge the battery. Can anybody explain the following screenshot? I run nightly cm11 from pawtip in the most recent nightly...

Most probably a hardware issue. You might want to get it to the nearest Samsung Service Center and get the USB Port (or whatever you call it) replaced
I tried to fix the USB port. I teared down my mobile until I got the USB port in my hands and put the pcb under my microscope. I saw a corroded connection from the port to the motherboard. But I don't have a proper solder unit to repair that. So I tried with my big fat soldering iron....and killed one connection. I managed to repair that, so I have the same faulty mobile as before. My next try will be a wireless charging mod (with parts from a palm mobile).
But I bought a spare I9000 already for 50 Euros......
Hi, I wanna ask if my PB is original. I already asked in miui forum but didn't get satisfied answer, so i decided to ask you guys
My PB has a some fake outside look indications, like all beige usb port, full white mi logo, and dark text on bottom. But I'm still confused whether it's real or fake because it has short circuit protection, led will turn off if I hold power button when charging, and can charge the phone while it connected to power adapter. (also the usb cable comes in clean, well built plastic finish, and doesn't has mi or usb logo on it, & box package is made of plastic coated cardboard & has security label & unique code, some said the fake one code also granted as original or the codes are legit??)

I would say yours is fake.
I visited that thread several times before i posted here. This was my thoughts, but somehow my security geniune key was verified as an original. Also few peoples have the exact PB condition as mine, two of them opened the case and have LG battery in it.

Hey guys!
My phone started having troubles with the touch (how unexpected right?)
Well, the thing is, when I was gonna remove the digitizer connector cable, I tried pulling the black plastic thing backwards instead of flipping it up.
Reason I did this was because I've repaired a few laptops and they had the type of connector were you pull the plastic thing back to release the connector.
The black plastic thing broke off in half so now I can't securely connect the digitizer anymore.
So, question is, can I get a replacement? I took one from another old HTC phone but it's not the correct one. (Lenght wise is correct, but not with the holes for the pins)
At 1:54 it shows the thing I'm talking about.
Youtube link (imbedded link didnt work)
Also attaches a printscreen of it for less hassle.

The black plastic piece that shows is the one I'm talking about!
Better view:
I don't even know the name of these parts so I don't even know what to search for. Please help me out guys.
Probably best way is to buy a new complete connector and remove the black plastic piece and fasten it onto the phones one.
Kind regards,
Tony
EDIT: Note sure if it's the same, but found this on ebay:

Is this the same type?
Nobody?
Hello
After 1,5 year of use my phone i cracked my screen. I decided to pay for repair screen but Service center said me that only offer replace to new phone Service Centre charge very high for replacing phone. I got my phone back and I decided to replace the screen and by the way the battery itself.
Screen is not original but work However, I have doubts about battery originality:
Original removed from phone looks like this:

New replacement:
Flex is different and hard to connect to PCB
Many sellers say that is original from Nokia.
Why is available two types of batteries with different flex cable?
Reason I ask is because my new battery working bad only 7-8 hours without using phone. Accu battery showing 45% oryginal capacity.
Looking at ebay it seems that all batteries manufactured in 2017 have the straight power ribbon cable, and the newer ones have the "S" shaped ribbon cable.
Considering the movement of the power plug it might be that the "S" bend was added as a revision to the newer batteries, as the old design could put some stress during plug/unplug of the battery, and that ribbon is quite stiff, as it's made of thick copper to handle the high current.
So all in all it seems possible that the "S" bend is in fact used in 2018 and newer OEM batteries for Nokia 8, but at the same time it's still highly likely that you got either a fake one, or a used/old one with limited capacity.
Sucks that there are no official manuals available for this, and even no real way of verifying if the battery/part is actually original.
