[Q] P990 dead after short circuit - LG Optimus 2x

Hi,
I wrecked my o2x using a faulty charger that probably caused a short circuit. I would like to repair the phone but have no idea what part is damaged. I image the micro board has to be replaced but i am not sure. Any of you have an idea if that is correct.

Yes, the board must be replaced in that case. If that was really a short curcuit, your whole (internal) memory could be damaged. Even if everything else would be ok, there would be no chance for you to boot or to repair the device without changing the whole motherboard. If I were you, I'd buy a used O2x or buy a new, different device. If you buy an used O2x, i wouldn't recommend swapping the motherboards for using your old O2x again because other stuff could also be broken.

Where to buy replacement motherboard for kaiser

Yup, just like the title says.
And before anyone yells at me, YES i did the search button but nothing...
I checked ebay, and for some reason no one has a motherboard... and I don't want to risk it with buying one with a cracked screen that might have a messed motherboard.
HTC wants to charge me $352.26 for a new motherboard AND lcd... when only the motherboard wasn't working (last i checked, the lcd was working... unless THEY did something at the repair)
I've seen this before in another thread. I believe the consensus was that there was no place to buy them except risking eBay.
Damn...
So how much do you think HTC would charge to repair the motherboard separately from the LCD ?

[Q] Milestone repair/spare parts?

One day I was charging my Milestone via USB and I unplugged it. The USB pins came out with the charger. My carrier told me that it was user-induced damage and not covered by the warranty, as well as telling me that you can't replace the charging port, so I'd simply have to buy a new phone.
This was quite unacceptable to me, so I went around to cellphone repairing shops and none of them have been able to fix it. In fact, the most recent attempted fix has left the back panel ripped apart, too!
The phone was in perfect condition before.
So does anyone know where I can find this elusive charging port - is it so special to the milestone that I can't replace it with another phone's USB port? I also need international shipping. Yes, pigs fly.
I have a dead Motorola Droid.
It sure is the same charging port.
PM if you are interested, I can ship worldwide.

I see you're still trying to get your phone to work. I may take you up on the offer, but I'm going to try one last phone technician to see if he can fix it. If he can't, I'll find out if it's just because of the port or because of general incompetence. Then I might be able to take the phone off you. Thanks for the offer.
Hi I am looking for a motherboard for my milestone. I am from Germany. My Milestone has a water damage. The only thing that does not work is the touch.
I think if I were an undamaged motherboard in it have ,it work again.
Does your motherboard?
Dear Greetings from Germany Misch xD
won't you need a new touch panel as well? if ur mother board failed, how did u determine touch doesn't work?
Hi
Hmm I think that the motherboard is damage. Because it has water damage suffered.
but maybe I should first install a new touch. Although I think the honest, the motherboard is scrap.
Do you have to sell a Touch?
thx

Xperia Z having USB problems?

I've been using this Xperia Z for about 2 years now, I haven't root it or anything like that. It started a few weeks ago after a drop (I'm not sure if it's related, the drop was quite mild compared to everything it has been through). The battery fell out, because I got the mic replaced from water damage and the technician did a lousy job gluing the backplate back on, I also removed it myself to help it recover from a second water damage a few months ago.
Now, the phone seems to be having problems with its USB port. Either that or it's a software problem. When I plug it in my wall charger, it detects its but won't charge until the battery is completely empty (htt p://postimg.org/image/z3lvehtxn/). No pc will detect it when plugged in via USB (MTP & MSC mode tried with and without USB debugging), so I can't flash any roms to it try to fix it, it has also been factory reset twice. Tried different chargers and cables, none of them made any difference.
Yes, I should probably get a new phone, but as a broke student I don't have a lot of money to spare
you can eliminate the possibility of a software related issue by flashing smth from the external sd card, even try flashing another kernel just to make sure, if not that then im sorry but it should be hardware
the drop was quite mild compared to everything it has been through

The battery fell out

Well.... thats "mild drop"...
Not to mention that Battery is self is glued to housing(two peaces of double side tape, to be more precise) and everytime when I had to mess with internal of XZ it was actually pain to remove it without brutal force.
Other thing worth mentioning is that battery on XZ is really... sensitive, especially controllers inside battery and pins on connector. Even slightly damage can totally brick your phone.
And microUSB connector? Its hard to tell, but I can say that connector is self is not damaged, because as you mentioned, PC detect is without a problem, the same with charger. In terms of durability I can say that microUSB port on XZ is actually one of best I encounter. Its damn hard to damage it as far as you dont put there screwdriver..
I can say that fist of all, as @aaronkatrini mentioned back up what you need, and then flash new clean rom, if problem is still there, its probably battery it self or one of controller that was damaged. In the first case, new battery should cost about 10-15Euro(original) in second case you are more screwed because cost of repair/new board is unprofitable.
Also taking in to the account that XZ new cost now about 120Euro(I love that price falls of phones jump from 600 to 120 in less than 3years...) I could say that you can buy BETTER phone for 120-150Euro, even Xperia Z1Compact or Xperia Z2 cost 150-200Euro.
Student or not, 150euro is not much if you use phone for work so with small savings you could buy it in less than two months, and trust me, Xperia Z1Compact still can kick ass even if it have smaller screen.

Maybe it's time for a new phone.
The guy who repaired my phone took the battery out and didn't even glue it back on, so it comes off easily. All the pc I tried to connect it to won't detect the phone, so it's impossible to flash it with a PC. Is it possible to flash a new rom with an SD card? I remember doing so with an Acer A500 to fix a wifi issue and it worked.

Yes you can, root with kingroot, flash the recovery, boot into recovery and flash. Read first

Root was a success, still figuring out how to flash without a PC

Did I finally destroy my Nexus 6?

My nexus 6's charging port doesn't work so I only use wireless now
So I was messing around with theming my nexus and it started crashing and shutting down over and over again so I gave up on undoing it and went straight to recovery but when I was pressing the buttons in TWRP I fat fingered Internal Storage and wiped everything off of my SD Card.
So can I use TWRP's terminal to wireless ADB and flash a new rom onto it, is there another way to save my Nexus, or should I just give up and get a new phone?
I would say your best bet would be to fix the charging port.
Have you attempted the toothpick trick? It’s already broke so you really can’t do any more damage.
You can also buy a brand new charging port on eBay for $5, though I must admit I’ve never attempted that replacement on a nexus 6 so I can’t speak as to how hard or easy that is.
I suspect that changing the port will be hard. It is soldered to the motherboard, and soldering a phone requires special knowledge and tools.

Its very easy to solder and its pretty cheap to buy one. You can get a soldering iron from walmart.

Technical question about USB C port replacement

I have a Razer Phone 2 with the infamous non-working USB C port. There seems to be very little supply for the board itself unless it's a used part and those seem to be farelt expensive. Looking at a teardown video of the phone it looks as though the port itself is attached to a flimsy ribbon type cable attachment. If anyone has any experience with this specific part could you please tell me if there are solder points that could be either reconnected or replaced with a completely new port without replacing the whole board? A friend of mine has a a fair bit of know how when it comes to doing repairs of this sort, but I'd hate to take it apart to try and replace the port it self and risk damaging the seal of the device for no reason at all if this procedure is not even possible without a replacement of the full part. Thank you in advance for any replies. I know this question might be a long shot, but we are just trying to weigh our options and figured someone on here might have the experience to point us in the right direction.

I have the same problem. And since sending it back to Razer( don't get me started on how much there customer support sucks!) would cost more than buying a used phone 2. I am thinking to replace the port. Did you have any luck?
I work in a repair shop where I get these from time to time. You can try a used charge port board, but that doesn't always fix it and that seems to be a temporary fix. I have yet to find the root cause of the charging bootloop on the nearly dozen rp2's I have
