Project Electric Himalaya - MDA II, XDA II, 2060 General

Hello to all. I'm a "new" member to the XDA-Dev community, and I am today presenting a document on my project that I've been dreaming about for 2 years or so. Finally, I had enough time to take time off my schedule to do something significant today - start this project officially.
I have an O2 XDA II with a broken connector. I will be attempting to hardwire an electrical source to the device by as many means possible. I have created this thread for people to come together and discuss any information they might have, any thoughts/ideas they want to share, or any observation(s) on their own experiments with this device.
http://s21.photobucket.com/albums/b296/tubecena/?action=view&current=himalaya.jpg
ps. : Here is something i forgot to add to the drawing :- At the end of the two wires in the end, I aim to put a USB male/female (haven't decided). Maybe i'll even redesign the area of the connector, but that would result in heavy work. We'll see how it goes. (and see how this thread gets feedback)
Here's something that might kickstart your contribution to this thread :
- Will it be possible to run the device without a battery with a charger of 5V?
- Will it be possible to join the two plates, positive (1+2) and negative (5+6), together, and get more power? Will there be any changes? Will there be a performance hike?
- What will happen to the device if a charger of 5.2V is used?
- If the two end wires are left not connected to a source, will an energy leak of any kind happen?
- Will the length of the wires significantly increase resistance and therefore reduce battery life?
I'm new here, go easy on me! >.<
Thanks for your time, and effort.

your questions are mainly in the general electric cat rather then himalya really
"- Will it be possible to run the device without a battery with a charger of 5V?"
yes unless the device detect the batt present and refuse to work without it
"- What will happen to the device if a charger of 5.2V is used?"
thumb rule is 20% each way without any problem
"- If the two end wires are left not connected to a source, will an energy leak of any kind happen?"
electrons travel from + to minus can't travel over air unless it's very hf
"- Will the length of the wires significantly increase resistance and therefore reduce battery life?"
there are many sites which let you calc the resistence of wires over lenght
but if you don't make them longer then 50cm you should not worry

Ah, thank you for your reply. Yes maybe you are right about the "electrical category" part, but since I was working on Himalaya, I might have just gotten a little over-excited and thought I might start a "project". Right you are, indeed this is purely electrical stuffs, but if you/anyone else might have any other information or ideas to refurbish your Himalaya, maybe this might be the place?
I was thinking of making use of the cradle from XDA II, resulting in a rewiring of the cradle and the device. Then that would mean that I need alot of USB cables, a drill, and maybe some wood? Well, if anyone has any points to bring up, speak up yeah?
In any case, IF I do decide to make something to help those dead Himalayas (like I said earlier, remodelling the cradle and device), then we'll have this thread as a tut.
Thanks and have a nice day people.

DEAD Hima.
okay, so i took two wires, connected the battery and the device (one plate and one pin each) and tried to fire up the device. It wouldn't start. I reinserted the battery to the Hima and it wouldn't fire up. I'm guessing that it's DEAD. Anyone might want to help me on this one?
- my connector is dead.
- my 2 batts are fully charged, still no avail. (not dead batt i guess)
- i charged my backup batt but still no avail.
- either there is an overall power undersurge(i'm just shooting random thoughts), or the RED SWITCH is causing the problems. coz the red switch is indeed loose"r", or, more loose, than before. Maybe I hit it abit too hard in the process and thought the battery did it, i'm not sure. Any help would be appreciated.
Oh and I'm buying a SECOND HAND PDA/XDA/WMTS DEV. I'm situated in Singapore. And I just need a very cheap one. I wouldn't mind if it has 1/10 cosmetics, coz i just need it to let my mum play solitaire. She's an avid player and would be very very cranky if she doesn't play in every few hours. Would preferably consider a very rundown XDA II, or XDA IIs, provided the cost is below SGD 70. Thanks and have a nice day people.
ps. even if it's not rundown, just pm me, we'll see how it goes. I need this asap!

Connector broken
Hi,
I have the same problem, my PDA connector (22 pins) is broken and I would like to connect directly the power on the battery pins (6 pins connector) but I dont know where are the + and - on these 6 pins!!!
Thanks for your help,
TD.

thats why we made a wiki for you
http://wiki.xda-developers.com/index.php?pagename=Connectors

completely broken
No because the 22 pins connector is completely broken (motherboard too)!!
But when I plug a charged battery, it's OK...

curious

Need help (Qtek2020)

Hi all
yesterday, while trying to put my device into my jeans pocket, i left it and it fall down to the ground... No damage at the moment after a first check... everything ok... BUT... after coming back home, i've put it into the connection base and anything happened... i've tried softreset but anything happened too.... so i've noticed, looking at the bottom of the qtek, that the port for the cable/base connection wasn't ok.
Here is the problem.... i get no activesync connection or power charging because the port is damaged... i've found that this port moves in every direction and so it isn't well attached to the mainboard. So i decided to disassemble the device to understand what is the problem whit my qtek.
After disassembling it, i noticed that the port has lost the weld that locks it to the mainboard...
And now??? What to do??? The port is completely detached and i think that there is no way to weld it again to the MB.
I'm out of warranty time too and i think that the warranty doesn't cover this kind of problem even because the technician will understand the reason of the unwelding.... and even because i'm not using my original rom from qtek....
So i thought one thing... is there any way to find a cable to connect the device from the port that i found just under the battery??? Where can i find the right cable??? And will it be usefull to get back again all the functionalities???
Please help.... i don't want to break up from my qtek so soon.... and i would like to wait few months before to buy a new device... (universal).
Hope someone will give me some advices... or suggestions.
Bye.... MINDGAP.
Anyone's got an advice for me??? Anyone can help???
I'm in troubloe here and i would like to understand if i could make my own cable to use from the back door port that i found under the battery cover of my device.
I tried to look in the himalaya wiki page but i found anything about this port.... only connection for the main port... that i can't use anymore because it's completely distroyed....
Please help me i can't believe that i'have to throw away my pocket pc only because of this problem....
What i would like to understand is if i can weld the port back again to the MB or even to give power from the port that is placed under the battery to use it only like Navigator in my car.
Please let me know if i can find a cable or a different solution in order to get my device back with all functionalities... i could even send the device to someone who could repair it and send it back again.
I would pay to have it back repaired.
Hope someone will help.
Thanks and have a nice day!
some images from the disaster!!!!
ok... here u are some images taken this afternoon.... featuring my POOR DEVICE..... terribly wounded.... almost dead!!!!
Hope these images will help you in trying to find a solution....
THIS IS THE SITUATION HERE.......

THE CONNECTOR IS FULLY DETACHED FROM THE MB.... AND I DON'T KNOW WHERE TO BUY ONE BRAND NEW... OR IF I CAN USE THIS ONE AGAIN.......
HERE U ARE TWO IMAGES OF THE MB WITHOUT THE CONNECTOR... AS U CAN SEE.... THE MB IS NOT DAMAGED AT ALL..... AND I THINK THAT THERE COULD BE A WAY TO RESOLD THE CONNECTOR......
ONE DOUBT ABOUT THIS LAST PICTURE.... IS THE SECONDARY PORT USABLE???? WHERE CAN I FIND A CABLE OR CONNECTOR THAT MATCH WITH IT????
LAST PICTURES SHOW THE STATUS OF THE CONNECTOR AND THE CAGE THAT PROTECTS IT.... IS THERE ANYWAY TO USE THEM AGAIN???
I HOPE THAT SOMEONE HAS SOME SOGGESTIONS FOR ME BECAUSE AFTER A SEARCH ON THE FORUM I FOUND ONLY INFORMATION ABOUT THE CONNECTORS BUT NOT IF IT IS POSSIBLE TO SOLDER AND TO BUY A NEW ONE.......
Thanks in advance just for reading this post.... and thanks much more for answering.....

if this is still a problem for you and all else has failed then I would be preperd to try and resoulder the connection for you I do have all the right equipment and I have experance as I have chiped sevreal Xboxs and thay have a fue fiddley bits plus I was traned to militry spec in solderin at EEV but there is no garantee but from what I have seen I may well be able to do the job. You can pm me in here and I will be watching this thred.

Well I've had also this problem once. I have broken this connector off the board with the charging adapter from charger. Anyway it isn't too difficult to repair that if you are a bit handy. Just use a micro-solder and carefuly sold the connector back.
Important:
1. Don't plug the battery while you repair that!
2. Use the rosin to prevent decant the pewter on the pins
3. Use the pewter-suction band to remove the pewter from the connector if is it too much
4. When finished,use a mechanical tools to remove the rest of the rosin. Don't use alcohol based solvents(I have damaged the JoyStick with Isopropyl-Alcohol)!
5. Ensure that all pins are solded separately and no pins are bridged by soldering!
Probably this will result as a Hard-reset,because the repair will take probably more than 30mins without battery or you can short-circuit the backup battery. Therefore backup all your data(WM5-Only RAMdisk).
In the meantime, you could still communicate with your wounded beast say using Activesync over Bluetooth (that will sort out your sync issues and allow you to have an up to date copy of your data). Similalry if you have or can get an SD card you can dunp copies of data onto that too.
Also if you can get your hands on a second battery quickly enough, use the cradle to keep one bat on charge while using the other in the device. Regularly swap over will mean that you can at least use your Himam until you are in a position to solder new/old parts.

Can some one post a topic or a detailed manual on how to disassemble the hima?
Regds Aldo
...
You need to remove the black antenna cover. After that is it easy. Just few screws. Remove all parts in cover neighbourhood(card,stylus,antenna connector cap). Then release both hooks located at the top of the battery with your nail or small screwdriver pushed into the stylus hole and at the volume-slider location. After that release fixings in surround of the card slot. Do it easily and carefully! Otherwise you can break the plastic. You can find also the service manual at wiki.xda-dev,but DON'T do it that way! That procedure is wrong.
Disassaemble
Can anyone send some pictures on how to disassemble the qtek. Which screws do we need to pull out and how do you do that?
hi i did assemble the connector my self , but i m in Egypt , Cairo ...if you like call me on my handy

Cingular 8525 won't turn on

I have a Cingular 8525 and it just recently turned off and will not turn back on. I've removed both the battery and the sim and let it sit for a while, put them back in and it still won't turn on. It was cabled to my laptop at the time. No indicator lights at the top turn on at all, even with the wall charger/adapter plugged into it. I've already requested a warranty replacement from Cingular, but apparently they are only sending the phone and not the battery. The person I spoke with said I could go to a Cingular corporate store and have them order me a new battery (none of them in my area have the battery in stock).
Any suggestions? Can someone confirm that the phone will turn on with the battery out and the phone plugged into the wall charger? Can somebody turn off their phone and plug it into the adapter with the phone off and tell me if any lights are lit? Any help would be greatly appreciated. Thanks.
Hi
With no battery in the phone will not operate at all. There should be a RED Led lit up to indicate that the device is failing to charge.
Mike
I know this thread is old, but hopefully someone can help. My 8525 stopped working as of recently. When I plug it up to the charger, there is a red LED..does this mean my battery is junk? or the phone
if there's no battery and you connect the charger, a red light will show......so most likely it would be your battery that's junk. check your battery connections first.
Same problem!
The phone was connected to my computer and was in the middle of replying to a text message when the phone rang. When I went to answer the phone froze and wouldn't respond. I hit the soft rest button and it stayed frozen. I took the battery out and then I got nothing. Won't turn back on. Any suggestions?
Thanks in advance for your help.

If you get no LEDs showing when you connect the charger, then the fuze may be blown.
Fuse location
http://www.mikechannon.net/PDF%20Manuals/Hermes%20Fuse%20Location.pdf
Mike
Fixed
I did a search for the fuse placement on the 8525 and found several screen shoots. I used a pair of tweezers to bridge the gap to see if it was the fuse or not. It worked!!
Replacing a fuse this size on a MB that small is almost impossible for the average person. What I did was place a small amount of solder across the fuse. Everything looks good so far. Of course I will now place the phone inside a sauce pan and leave it on top of the stove top to recharge until I find one on eBay with a broken LCD!
Thanks for the heads up. I'm was hoping for a "normal" fix for this problem. I very grateful for this site and all the users who lend a helping hand.
Cheers, David
My 8525 (HTC Hermes 100) just quit working
Last night I had no problems used the phone while out...got home and my phone just wouldn't respond. No soft reset, no taking out the battery, no charging via wall or by computer worked. No light display to indicate it was charging, or battery was low I tried all these possibilities.
This phone has never touched the ground. (I just got it 2 wks. ago. Its my second HTC Hermes, never had a problem with the other.) the power was at 50 percent so it wasn't dead even...
The phone is unlocked, I don't use ATT, even though this phone is in immaculate condition, it is used, I bought it from someone else who barely used it, so no warranty.
I have taken my other Hermes apart to fix the ribbon cable and screen...I would hate to have to do the same with this phone it still has the void stickers in place.
Bleh, look I love this phone, and if anyone has any suggestions I welcome them as I know this thread is old. I would hate to junk a phone that I can just fix...
I believe u need a charger that could charge the battery outside of phone then when finished put back in battery and see if it turns on u may need a multimeter to test batterys DC volts to see if is below 3.2 volts
Okay - first sorry for opening this deadish thread. But figured better than opening up a new one.
My phone is doing the same thing - it just quit working randomly. Went online to get an address to our next destination. Got there, and picked up phone to make a call - and it wont turn on.
i noticed a capacitor looking thing near the charger that looks like it's cracked or messed up.
Can Mike or someone look at theirs and let me know if it looks similar? Thanks to XDA, this 5 year old phone still feels brand new - and I really haven't seen a need to replace it for at least another year.
Any help, appreciated.

(JUST IN CASE anyone gets confused (get it haha) that is not a picture of the fuse in the picture shown above)​
Assuming you have no LEDs showing even when the charger is plugged in, then it is very likely to be the fuse:

Not that I recommend the old tweezer trick mentioned in a post above! - but it might be worth trying. Or soldering across the fuse. (Neither of these things is at all professional, but I'm old enough to remember putting paperclips in fuse holders as a strictly temporary measure you understand​
If you have any LEDs showing then it is not the fuse.​

HERMES
I say if you can find someone to take a look at it, you may be able to fix the issue. For me it was as easy as seeing if it was the battery vs. the usb connector vs. even the battery indication LED at the top the phone.
Issue was a mix of the battery and the connector. Fixed and though I have an iPhone my HERMES will always be number 1!

Thanks Mike! You know - I was going to post "please don't mind the dust" then i figured, everyone else's gotta look like that. i guess not, eh?
anyhow i realized that that thing wasn't the fuse - from finding this thread before I posted, I was actually able to get to the fuse. My eyes caught that funky looking thing and said, hey this doesn't look right. So I figured it might be the issue (okay, i hoped it's the issue, because even with my fat sausage fingers, I can probably try swap that out).
I will try the ole tweezer trick to see if it will work. For now I'm in an BJ II - no touch screen and no WinMo (no matter how much we've grown around here, i still like the WinMo interface).

btw, how much did you fix run you?
BTW Mike have you ever insert tweazer in the EXTusb port?
All the USB cables have some kind of shortcircuit so i asume that the pines are just to low and i need to rise them a lil... do you think it can be done? thans a lot

Not tweezers, but I have seen reports that they can be tweaked with a pin. However, you'll need a magnifying glas or preferrably a watchmakers Loupe. I'm lucky, I do watch repairs as a hobby so I have a Loupe and it makes life much easier!
Pins in the USB port do get bent easily and can cross each other.

help!
Last night i was surfing the net on the handst htc tytn, i in the meantime connected to my laptop thru usb n transfering mp3 songs, while doing so the handst hangs, i removed the battery, then when i tried to restart it boots up till microsoft corporation and doesnt go beynd that, no hard reset helps am using windows mobile 6.5 titanium hd. plz help
OK so I think i was able to confirm that it WAS infact the fuse. Tweezing it with my giant tweezer was difficult, but did work (I saw the RED led light come on).
Now - the question is what do I do? I am not sure I have the skill to solder this tiny thing w.o. getting solder ALL over the components around there. BUT at the same time, to me the device is dead, I'll only be putting the nails on the coffin if I mess it up.
Does anyone know if a regular ole cell phone shop can fix this? Or am I going to need to spend more than the device's street value to get it fixed ala the ole cheaper to replace than to fix mantra?
Advice, appreciated
Personally, put the repair money towards a new phone... It will probably be expensive..
Sorry, but as much as I loved the Hermes, its getting just a bit long in the tooth... Newer devices have more ram, and more little things, like GPS and so forth..
Though it was a good Phone, my Hermes has been retired for a younger faster model, aren't we all at some point...

USB mini Powered LED

I wanna power a small LED with the usb mini jack on the G1....
I cut a usb cable in half plugged in the usb port to the computer....touched the connectors on the led and the light turned on....
Plugged in the Usb mini jack to the phone touched the connectors and nothing....
I know that we can use the usb jack to power our headphones......what i dont know is how to get the phone to power the LED....
i dont know how much power is used to get the headphones to work or what triggers them to start working when we play audio....Would an app like a toggle have to be implemented to make the usb mini port start pumpin out juice for the LED?
come on guys....a lil help here
to the top of the list i say

All usb connectors are the same.. thats why the U in usb stands for Universal Just make sure you have the right pins/wires.
I have to ask though... what's the point of this..?

Not quite what he meant. He meant will it work with a mini USB or does it require one of the weird HTC-USB pins.
And as ezterry said it goes between pin 5 and 8 -- and USB only has 4 pins, so no. It certainly requires weird HTC-USB.

yeah. ...it seems like the connector is universal but not the inside of it. ..I've seen 4 pin, 5 pin, 8 pin, 10 pin, 11 pin. ...but ill try testing some of those out too.
I want a lil usb dongle flashlight....n maybe it can help out with taking pictures in low light conditions. .... if it lights up nice n pix come out good with it maybe some1 can help me get it to activate with a toggle or make the phone recognize it as a flash.....personally im fine with just pluggin it in real quick if ima snap a pic....
I have another lil idea for the cam but its ugly and I don't know how well it will work yet so ima keep it on the hush hush till I test it
lol, sounds like you are trying to make a flash for the camera. If so, sounds excellent!
That would require storing up some juice to make the flash really bright though.

i wish i had the "know how" to make a real flash.....so far my idea is get some light shining out at a constant rate...im being told by some other ppl that the led im tryna use is too inefficient so im gonna see what else they can recommend...
they said theres other ones instead of the one i want that should shine 3 x brighter....i know theres some bright minds here that can help me improve my idea...
hopefully this generates a lil interest and others will chime in....
i hacked up a usb cable i had n its only 4 pins...so ima have to order an 11 pin one like ezterry said...so before i can go on i have to wait for this stuff to get here
does anyone know what kind of LEDs are used on other phones like the N1 or HD2? Just so we can get an idea of how powerful these lights would need to be to work well.
And more or less how much power can we get out of the usb port?
ezeterry?
Cree LEDs - http://www.cree.com/
Luxeon Flash LEDs - http://www.philipslumileds.com/products/luxeon-flash
I would think though in order for this to work, you would have to program in to your photo software the timing to send a command to the usb port (not even sure if it can be done) to flash at the appropriate time. Plus, like I said before, you would have to store up some energy in order to give your led some power to get it to light up bright enough. Correct me if I'm wrong though, just a halfway educated guess. lol
yeah for now ima keep the design simple...if it lights up ill see how much light were gettin. ..if its good then ill be happy
if its crap ill test out other options....
storing voltage is used on xenon flash types, which operate like a strobe light / disposable camera.
LED's need a regulated source of voltage and current... 3.3 - 5v is usually the range for LED's.
looks like they did something along the lines of what i want for the ipod/phone....not pointing the way i want but...makes me think my idea wont have a problem workin

[Jan 15] [Q] USB Charge Data Port connection is finicky. Please help.

Today the phone fell from the desk with the charger cable plugged into the phone. Now it won't charge/make a connection unless the USB cable is forced to plug in at a downward angle:

}
If the plug is in any other way, the phone will not recognize it.
This is bloody annoying!!! I can't charge the phone anymore unless the cable is resting on something and I can no longer listen to music in my car (since the road vibrations cause the plug to move around).
So my questions are:
Is there a way to fix this by way of opening it up and soldering?
Is there a way to replace the USB port?
I'm tempted to just ghetto rig it by creating a "lift" within the port by way of a small amount of Gorilla Glue (or similar resin)...but that seems 'temporary' to me.
So here's to hoping that someone else here has had this issue (besides stupid ol me) and happens to have a wonderful solution for this issue. Also, if it matters, I'm in the San Francisco Bay Area. So if you know someone that does this kind of phone repair, please recommend them me. Thanks!
I'll assume you ruled out the actual cable?
Just by experience with other hardware, I'd say either something is bent/broke or the solder joints opened up (most likely this, and I hope it's not surface mount...). No idea how easy/hard it is to open up a HD2, as I've been lucky enough to not have to , but once that's done, should be easy enough to inspect the connector, depending on electronics skills.
i checked the phone with 3 different cables. same symptoms.
yeah...i'm guessing (hoping) it needs a resoldering job. i suppose i should start looking for pictures of the guts.
I have exactly this as well. No desire to open my HD2 up so I've just taken to lying my wallet down next to it when I charge, and laying the wire over it. It's really annoying to have to do, though.
Hello there. Sad to hear that you have got this problem. There is nothing you can do to fix it, yourself. I had this problem for about 2 months ago, when my HD2 suddenly had the same problem, and would only charge when the usb cable was forced in a definite way. The situation is, that the micro-usb "house", solved to the mainboard, is BROKEN from the soldering. Some of the pins, is broken off, and when you push the usb cable upwards, the pins will again make a connection with the mainboard, but when you slip, it will loose the connection...
I send mine in for a repair, but HTC said that it was my own fault. They would not make a repair, unless I paid for a new mainboard. You can see picture from the repair center:
Or see my other thread: http://forum.xda-developers.com/showthread.php?t=814053.
So what can you do now?
You can open up your HD2, to see the broken traces from usb housing, following this guide: http://pocketnow.com/hardware-1/official-htc-hd2-disassembly-assembly-training-videos-leaked - But you will quickly realize that it's IMPOSSIBLE to solder the pins. It's VERY small, and it's not only metal pins, but also some kind of micro wires, 5 pieces, and you can't just solder them...
The disassemble of HD2 it's not that hard, you will though need to buy some tools.
To get your HD2 working again: Get a new main board. From where? Good question. I looked at ebay, and searched for a very loooong, for a mainboard, but it's impossible to buy one, unless you find a hd2 on ebay with a broken screen, and the mainboard is working, for some small amounts, and change the mainboard yourself.
I waited for about 1 month for a mainboard, but couldn't find one. So i simply bought a secondhand HD2, for a small amount..
I hope this helps to clear up some things. Just PM if you have some questions.
Fuuuuuuuuuuuuuuuuuuu... that's a downer.
I finally got this phone all perfect with the NAND Android.
Sigh... bummer that HTC had to make the USB housing irreplaceable.
That photo is helpful. That's out of my league. I've never soldered anything with that small of a footprint.
I'm looking for broken phones on eBay. Looks like they are going for 100 bones.
I think I'm going to try this one cell repair guy in town next week. Apparently he's a soldering virtuoso.
If that doesn't work, I guess I will have to replace the mainboard with one from eBay and hope that it doesn't have the same symptom I'm trying to rid of.
I will let you know if the repair guy has steady magic hands or not.
Truly truly frustrating...
Ah, surface mount =\ and the one in that pic actually lifted the pads themselves. If yours is anything like that pic, which I'll assume it's close, it looks like it should be possible to bridge the broken connection, but it will require a good quality temp-controlled soldering iron, fine tip, small wire, and excellent soldering skills. If the guy can hand-solder fine-pitch surface mount chips, this shouldn't be a problem.
The "fixed" connections would work, but wouldn't be 100% the strength of original. Some epoxy encompassing the connections and whole rear-end of the jack should strengthen it back up a bit.
So has anyone managed to fix this yet? Also, is there anything out there that can charge an extended battery without it having to be in the phone?
!!!SUCCESS!!!
SUCCESS!!!!*
the people i brought my phone too was able to fix it. it took a couple weeks for them to get their hands on a new USB port (apparently i destroyed it beyond repair). once they got a new one, it was soldered on.
*one slight niggle though: it takes 30 secs to transfer 100MB of data to the phone.
they "warned" me that they were able to to solder one of the pins, so data transfer may not be possible. so maybe the port is now acting as 'USB 1.0'. thankfully the only time i do data transfer is when i put MP3s and videos on it. and the occasional ROM/NAND flashing (which i don't do anymore since Cotulla/DFT's NAND Desire flash).
so besides that's little set back, i can charge/connect my phone without having to worry about losing connection to my computer or car.
but to be on the safe side, i no longer charge my phone via USB. i have purchased an external battery charger along with an extra battery. its been pretty sweet.
I've just see this post, for a couple of bucks, I think its' 70 or so u can get a charging mat, that will replace the usb charging feature. Just an idea.
Congrats! nick2k Good to know that it's doable. By the way it looks more like a rust on the image. What these guys had to say about the probable cause of that?

pk2_76; Mats are using dongles, connected to a phone by the very same micro USB port. While it might reduce the number of plug/unplug events, which wearing off the connector, the dongle itself is quite bulky to keep on all the time, and also might interfere with the holsters and skins. I'm still hoping for a special back cover rumored to be available from HTC with a mat-like charging accessory.
Well I just got one of the mains chargers off ebay, waiting for it to arrive. My port's getting worse so I need it sooner rather than later. Word of warning I guess, treat the connection with care!

Is there any definitive solution to the usb-c port problem?

Guys there is a piece or tutorial that definitively solves the problem of the usb-c port of this device, I like it very much and I didn't want to get rid of it !!

I've thought of many solutions, however, since my my USB-C port seems fine atm, I'm not fidgeting with it.
1st thing I tried was Wireless Charging.
This video above, gave me some hope, but the youtuber has not shared links to buy what worked for him and none of the high-end Qi Wireless Charging receivers I bought worked for me.
After researching a bit and trying multiple Qi Charging Receivers, I read somewhere, Wireless Charging receivers don't play well with phones that offer any type of fast charging, which our phones do.
2nd thing I tried is getting a magnetic cable, which looks something like the image below

}
However, the peice that went into the phone has quite a bit of thickness and felt if the phone were to ever fall on the charging port it would break the port and generally, I did not like the aesthetics of it, it was too thick. Check this video out if you are interested in it, it's for a similar phone (Video MP4 file)
3rd thing I considered was to DIY a battery case that would connect to the port and a cover that would be thick enough to cover the port and the battery case. Would then have an alternative charging method, like wireless or USB-C. I gave up on this as my port is fine as of now, since I bought a pre-owned phone, it's been working fine.
Currently, I only use an Amazon basics certified USB-C cable to charge the phone, I do not use the company supplied cable at all.
If you want to change the charging port yourself you can search on youtube you will find a video with reasonable knowledge on how to open up your phone and change the port yourself, like this one
The port itself at the time of writing this post costs 309 INR (maxbhi link)
Hope that helps!

there's none, you can fix it, but eventually, it's gonna broken again. The actual problem is the housing, it's put much pressure on the port so it wears so easily, especially when you're using your phone when charging, which most people often do even just for checking the notification.
In my opinion,
Change the port with the OEM original and replace that goddam USB cable that came with the phone,
That cable is the culprit, I use OnePlus dash cable
I was very luck to find a repair service that fixed the internal piece of hardware (I live in Rio de Janeiro, Brazil).
It took the guy approx. 2 hours to complete the job.
Note that he didn't replace the hardware, but fixed the original faulty component somehow instead.
If you order the OEM component from AliExpress or somewhere else and ask a technician to replace, it would take approx. 30 min.
After the job was done, the back of the phone was glued and kept strapped to the case with ribbons for half an hour.
Also I've bought a new cable, a highly recommended OEM one from Amazon. That was when the first signs of the problem emerged.
Now the fast charge is working again.
In the last few weeks of despair, I was applying pressure to the connector when attached to the port, by rising it or pushing it to the side, which only made things worse, since the internal component was absorbing all that pressure.
Don't do that. If the problem comes, try to replace the internal component asap.
One last piece of advice, don't charge and use the phone. Keep it quiet on a flat surface, like a table or chair.
I read somewhere so not sure of truths but.... the story said the problem was the fit being to loose and causing wear... The solution that the guy came up with was to put a small strip of cello tape carefully around the end of the USB c connector making the fit tighter... Seems like it could be a solution... I personally just keep changing the faulty bit.... The phones in a case so no need to professionally restick the back... Changing the part takes about five minutes
This is what I do after usb port is broken
Spoiler: Picture
You only need cutter blade and electricity solatip
So far it's work and my usb port not loose & broken again.
Hope that help

Hey there! OnePlus dash cable fits perfectly? Any issues so far?
I think there is no solution for this problem. I changed the usb-c board 5 times, the last one yesterday. I finally bought 5 more new, seemingly original boards from an Aliexpress seller, for about $ 16 in total. Here is the link to the article, for anyone interested:
