I'm not sure if my title makes any sense, so I will further explain here. I had to repair my charging port, while doing so I must have damaged the clip that the battery plugs into. It looks like a pin or two (that is soldered to the mobo) is a bit loose. My phone does not charge but will function when plugged in. I bought a replacement battery thinking I damaged that, when going to install I noticed the loose pins. Went through with the install anyway, and phone acts the same.
Is there any hope for my to resolder the pins back to the mobo? I want to get some input before I buy a soldering gun etc.

Resoldering battery connectors is normally a very difficult job, best to take it to someone experienced. If the solder pad is gone too you'll definitely need a professional.

Whilst replacing the screen on my m700 i managed to utterly nadge the main board by breaking off the clip that holds the screen ribbon in place. To make matters worse I completely fubarred the socket by pushing the ribbon in and bending all the pins over. Not only that I then managed to get the battery in backwards and fried a power component. So in short totally assed the main board up. Does anyone knoe how I can get hold of a replacement main board or the longest shot on the planet a place that could repair the stupid damage I have done?

I've seen a lot of parts for the Trinity online, but never a motherboard. I think you may have to send it in for service.

Anyone know where I can send this phone in either the UK or the Netherlands to be repaired?
Try to find ot from HTC's European web site....they must have a number or a telephone somwhere....now If you have messed around with the mainboard, to replace it, outside the guarantee it might be a costly process...maybe you will be better off with buying a second hand one and use yours for spare parts, when and if needed....better ask them for the cost before you send it
Hi,
I disassembled my N1 for changing the main flex cable (cutted power button) and in the disassembling procedure I noticed that one of the SMD components on the motherboard was de-soldered or not correctly soldered (twisted). I re-accommodated with a pair of tweezers and it did not hang loose (yet!).
What kind of function does this SMD do? Can I expect the phone to work?
I have experience with soldering iron but think this is too small for me.
I can't test it right now because my new main flex has not arrived yet.
Maybe you can solder it with an oven for CMS ?

I'm not very familiar with oven soldering; dunno if I will kill other components or If i need some kind of flux.
Also a heat gun would do the work but probably desolder other components.
I broke off a couple of the smd components right next to that connector (the screen connection) they effect color on the screen. Mine showed only red after I broke 2. It was usable but not pretty.

Thanks for your answer.
You broke those very same components?
As soon as I get my main flex i will try it and see if it report problems. It probably will as that component is there for something.
You might be able to re-flow it with a heat gun.

Actually I'm looking for a chinese reflow station with a hot air gun with a tiny nozzle. Probably will do the work but...
Should I use some kind of flux? Any recommendations? Never done a hot air reflow.
Looks like the same but hard to tell in the pics. I can't really see on my phone.
Sent from my HTC Desire using Tapatalk
that is a set of inline resistors, meaning it is quite a few connections, the best way is to use some flux from a needle and a soldering iron with a small tip,you could use a hot air machine but on a fully assembled board i would not recommend it.. flux is needed but you may be able to get away with a large soldering iron.
My advice would be to pay someone to fix it.. that way if they mess up ya get a new phone
Find someone with a reflow air knife, anyone who does SMT work would have one. It'd take 5 seconds to put that RP back on as long as you didn't break any of the pads doing whatever it is that you did that caused you to break it. Yikes.
May i ask you where u got the power cable? I need one too, how much was it? And is it hard to replace?
N1
I bought it on www.aliexpress.com
It was around USD$45.
I still don't receive it, as soon as I recive it I will report if the phone works and if it is an easy repair.
Best Regards.
The phone it's not turning on.
I tried it disassembled with the new main flex cable, motherboard and only lcd conencted.
Nothing happened when I press the power button.
The only sign of life is the ambar led that turns on when you connect the charger.
The tiny little SMD part fell off the mother board so it is completly unsoldered. Could this be the cause of not turning at all?
Looking forward to your answers.
Yes, if a single component is missing or even has a bridge in the solder, it could cause complete failure. There is a reason for it being there. If it were me, I would try to resolder it. Grab an iron and some wick and get what you can off of the board. Then try to reflow the part back on. If it works, great. If not, you still have a nice looking paperweight.
Well, I soldered the little SMD back with a soldering/hot air station but the motherboard still don't turn on.
It was working before, maybe I'm doing something wrong.
Thanks for your support.
Hey guys
Like many others my usb gone bust and my advent tn7 just became useless. Ive went to curries and explained about how this is a common issue but they dismissed it saying a broken charger port is my fault. I have searched several forms but still havent found any way of fixing it. Does anyone know how to get my tab to charge? Ive tried opening the tab but one side of it doesnt seem to come off. What are my options if any? Any help will be greatly appreciated. Thanks.

The best option would be to take it to a repair shop... it might cost you $50, but hopefully they can replace it with the right USB port (the one Nvidia used is slightly different from most micro-USB ports you see on devices, so it's not a very snug fit, hence the problem.)
I have the evga tn7 that i bought from newegg. Would they still honor my warrenty on the broken charging port even though I have my bootloader unlocked?
jon7701, I was thinking the same thing. I bought mine a couple of months ago and the charging port is being a little finicky.

Mine has to be plugged in a certain way or it refuses to charge outright. Even when I have it in the proper way it might not charge at all but reports its charging. The strange thing is that it can still detect what type of charging method (usb or AC) im using even though it wont charge.
I was able to fix my EVGA Tegra Note 7 usb connector using a re-flow soldering station (the type that uses hot air to melt solder), and it only took about 30 minutes. If you know an electrical engineer or serious electrical design enthusiast, they may have one. The problem is caused from the solder joints on the usb connector breaking. All I had to do is re-melt the solder and the problem was fixed. You cannot use a normal soldering iron because there are other components in the way. This happens on the Tegra Note because Nvidia specified a Micro-ab type connector instead of the Micro-b connector that most phones have. This allows accidental upside down insertion to damage the connector.
All you have to do is snap the plastic case apart, carefully remove the small circuit board that has the usb connector. The solder joint appears solid, but I was able to see the crack with a microscope and a trained eye. Use hot air to melt the solder, and resemble. Now I am just careful to plug the cable in right side up. If it breaks again, I am replacing it with a Micro-b connector.
I like having a re-flow soldering station. Every hacker should have one for replacing surface mount components and more extreme hacks (like upgrading internal flash, etc.).
sorry for necroing this post but i'm having the same issue. i've thought the same as you of replacing the port with a micro b. i have only one question: is there any problem with replacing it with a micro b? or no problem at all

Thanks a lot for your correct advise.
I had a long battle getting my Xolo Tegra Note fixed in Pune.
Xolo service center people told me that because I have down graded my tablet to KitKat, now motherboard is gone. After that I went to local mobile repair shop, he told me it's very difficult fix this as the joint are very small and soldering can damage other things as well.
After visiting a few repair shop in Pimpri market, I found a guy who did it. I found the same issue of minor crack which he found using multiple magnifying glasses.
It's better to visit a good repair shop not a small one as the issue won't be visible without magnifying glasses.
Let me know if anyone wants to get it fixed in India, Pune. I will share the mobile shop address.
Recently my phone was damaged through the charging port due to moisture. In the morning I typically bring my phone with me to keep track of time. Usually I would blow out the port to remove water but when I plugged in my charging cable later in the day, the connector got so hot it burned the tip of my fingers and melted some of its internal plastic into the port. So now I can only charge wirelessly. I'm thinking what if I purchase a magnetic connector and leave it there permanently and seal the gap with some metal purpose caulking. In the case I get moisture on the contacts I can just wipe it off.
Immediately I want to say it's a very bad idea, mainly because most caulking has an off-gassing effect that could be damaging to the sensitive innards of a phone. But! I'm surely willing to be impressed. Be leery not to get any on the actual contacts and use it sparingly, you may be OK.

When I get my phone back I'll post some pictures.
First of all, I have moved on long ago, my production phone is a Nexus 6. So with the N4 gathering dust in a drawer, I decide why not take a chance with it. The N4 was fully functional, but like many others had a partially splintered glass back. Years ago I had bought a replacement back that I never installed. So I thought, why not replace the back and with the back off replace the battery as well.
I made one mistake in the process. I didn't realize the battery had a wire taped to its side that that ended in a gold plug that attaches to a socket on the motherboard. When I removed the battery which was glued down I pulled the wire out of the plug. I then soldered the wire back onto the plug, and at least my voltmeter showed continuity.
One I reassembled battery is ok, wifi works, but no cell service. The phone sees the difference between the SIM being in or out, but no service. The SIM gave service before the surgery, and also does in another phone.
I've taken it apart and put it together a few times, making sure the plug is seated in the socket and the there is continuity between the bit of exposed wire and the plug..
One other thing caught my eye. The old battery has a silver foil backing apparently glued to it. The replacement battery does not. Could there be a shielding issue?
At any rate I thought I would ask for any suggestions. The loss of cell connection is not a tragedy. My plan is to use it to play with different roms while sticking with stock on the N6. for my real use.

This wire is coaxial type and because of the size it's almost impossible to repair it correctly.
I would suggest to buy a new one, form here:

or look on ebay/aliexpress/google/etc. for part number: EAD62290101
