broken charging connector... need a new/used mainboard.

My 2i's charging connector broke. Sent it back to O2's repair centre and they specifically said that the mainboard has to be changed. Anybody here know of any thrifty way to get hold of a mainboard or a something similar? Any help is greatly appreciated. Thanks.
Vincent

fixed same problem my self
Hi ,
I received a similar device from a collegue.
His charging connector was completely severed from his mainbord.
I opened the device and solderd it back on my self. Device is working again.
If you have te same problem maybe it's cheaper to find someone who can do this for you then looking for a replacement mailboard.
I have to say I had to try it 2 time because the connections where really tiny.

exactly...tiny...
You're right, it's very small, plus I have fat fingers. Well, maybe I should get someone to do it for me. I was hoping for a short cut solution and not too expensive one as well. I might try that after the holidays..

Hermes totally dead.

Since I brought my jasjam it hasnt had a good life. It has been bashed around a bit too much and I only have myself to blame. This unfortunatly has cause the white screen of death getting worse and worse. Taking apart and reseating the ribbon cable to the board appeared to help but it would soon start getting worse again. The short term fix was a thump accros the palm of my hand. Unfortunatly today this back fired in me and now the phone is totally dead. I am fortunate enough to have another Jasjam that i was sorting out a few problems for a friend and this gave me the ability to swap out batteries chargers etc to try and get mine to fire up. No good.
I have taken it apart and checked all cables to no avail. pluggin in usb or charger have no affect. no lights no responce of anysort.
Any suggestions would be a great help
Thanks

That's too much of a challenge to answer - could be any number of things. Without testing it with a multimeter I couldn't say.
What surprises me is that your friend lets you anywhere near his phone - and does he know you use his bits to test out your poor maltreated Hermes
I assume you have looked through the service manual to seek any clues?

Thanks f0r you reply Mike
Im sure what he doesnt know wont hurt him anyway its only battery and charger.
Had a look thriough the service manual nothing jumps up and pokes me in the eye. I guess its fairly safe to say the main board has had it.
I cant seem to find anywhere to buy a replacment board and more importantly how much they are so i can see if its viable.
any suggestions
Thanks

From my experience, you can only get motherboards from HTC or their repair outlets - this will cost lot$. Maybe if you're shelling out $$$ why not wait for the Kaiser?

please help my mate's dead Hermes
hi, this is to anyone who can help mainly prof and mikechannon. basically, i was trying to use my mates BRAND NEW hermes to repair my WLAN (Tmobile Hermes). it was working perfectly well until ran the RUU programme. i selected the 1.04SPL so that i could flash the hermes with the new NBH file i created. it flashed a 100% and it turned off and now its not coming back on. i plugged it into the charger, but no luck.i am afraid if i send it back to HTC, they might want to charge me for it. i love this phone badly, but sadly,i have given my mate mine. i dont mind sending this phone o anyone in the UK who can fix it. PLEASE HELP

I am not a flashing expert, so POF might be the first person to contact even if it's just to see if this is some recognised thing that can happen despite getting to 100%.
Can we assume the phone is completely dead? ie NO LEDs lit at all even when on charger?
Mike

reply for hermes (mikechannon)
yes it is totally dead. the LED only comes on RED when i take out the battery and stick in the charger.its not responding to anything. i have tried a HARD reset, no luck even a Soft reset too. i am now trying to use microsoft window CE 5 builder software, but i honestly dont think it will work. i really have to fix this phone. it a brand new phone.i tried ringing HTC europe but they are closed today. how can i check if its still under warranty. also, i bought it off some guy on ebay and just had it delivered this morning and now i have managed to brick it

Well I think you need to get a reply here or speak to one of the ROM gurus to see if this is a kniwn result of a faulty flash (seems odd to be but I'm no expert)
The phone is not completely dead if the RED led lights when the battey is out. It is meant to do this. Normally if the battey is faulty the LED will also go red when the battery is inserted.
Are you saying that when you put the battery in the Red LED goes out and no LEDs then show?
Mike

I had the same problem as well.
Red LED w/o battery, and NOTHING else.
Battery IN + charger : no LED
Anything else : no LED
Phone wouldnt boot
So I bought from eBay a broken 8525 that was reported to power up, but the screen was broken and some buttons were malfunctioning before the screen broke.
Swapped the motherboards and now I got a functional 8525.

yes, mikechannon, thats excatly what i am saying. when the battery is out and the charger is in, the RED LED comes on. but when the battery and the charger is in, nothing happens

I would have been tempted to say to check with another battery in case it was therefore a battery fault. BUT given what alkizmo says above it suggests the issue is as likely to be a blown component on the m/board. The Service Manual Hermes or Wizard ( I forget which) refers to a fuse. However nobody so far has identified a fuse as such. It may be another component (resistor perhaps) that is used to blow if current is exceeded. At present though we do not have sufficient info to either identify this component or bypass it.
Still think it's worth a casual inquiry to the ROM gurus to hear their view on whether this is hard or software related.

Hermes Dead Battery ??
The Red Light Will Not Work If The Charge Is More Than 50 Per Cent
So Try To Shutdown Your Hermes And Put The Usb Charger Then Reboot Your Hermes
May Be It Will Work

Having experienced blown motherboards on a laptop, a desktop and now a cellphone, I can attest to this : If NOTHING powers on at ALL, it is a hardware fault. Before you speak out for laptop/deskop, don't forget about the BIOS, if the BIOS is fried, the motherboard will still power up (fans spinning, lights turning on).
However, maybe that something in the software CAUSED the hardware issue. However, once the damage is done, no changes to the software (even if you could change the software without turning on the phone) would make a difference.

The red light shows when there is no battery as well and the charger is plugged, if there is no battery and the red light doesnt show, you got a problem.
And, shutting down/rebooting is not an option here. The guy's phone won't even light up. It's fried.
Last suggestion of hope : remove the battery and leave the phone unplugged for a whole day. Then put back the battery and do a hard reset attempt.
If this doesnt work, then I got nothing else, as I said, I resulted in replacing the motherboard.

if you cant get it working i will buy the back speaker off you

ok, i am an optimistic person so i will surely try your approach. one question though, as the phone is brand new, do you reckon if i send it back to HTC europe, can they fix it as it is still under warranty?

thanks a lot for your reply. i am an Optimist so i will surely give your method a try. one question though: do you reckon if i send it back to HTC europe, will they fix it as the phone is brand new and still under warranty.although, i bought the phone on ebay brand new from a seller for my mate.its a vodafone branded HTC. cheers

Authorized Dealer?

Usually, most companies only warranty items from authorized dealers. If the seller was an authorized dealer you are ok. If not, they "might" fix it. Call to make sure before sending it in.

Dead Hermes
My VPA Compact III v1605 seems to have the same type of problem - it only shows red lite when it is plugged in and battery is off, but... but I can also (hardly) recognise 4-colour bootloader-type screen, which blinks once and reappears every time I reset the device.
It doesn't communicate with computer, MTTY says "USB port can not open"...
The difference between usual bootloader screen and this one is that I can't recognise any characters (like IPL/SPL), or maybe because it's hardly seen, I can not see characters?..
Is there any chance to have this device repaired?

Ok, not sure I can help here, but first can we clarify something -
You say the red LED shows with the batter "off". Do you mean with the battery out of the phone?
Mike

Hi there,
i messed around a lot with the hermes hardware the last few weeks.
There's a lot of stuff in those mobile that could go wrong

Seems like there's some part messed up in hardware.
If you dropped it some times, maybe some component got damaged.
Please check the voltages on board firmly after pressing the power on button with battery inserted. Just like mikeshannon suggested
There have to 3.15V, 1.8v, and ~1.2V around the board.
I will take a picture from the mainboard with testpoints if you like.
Anyway you need some electric skills
Otherwise give to a service center or buy a new mainboard.

This is very similar to what happened to my device. After downgrading from olipro's hard-spl something went wrong. After flashing succeeded with 100% the device got restarted and there it was... nothing!!
What i found out in the meantime is that the IPL was not flashed correctly.
While trying to reflash the device with JTAG debugger, i examined that the NAND write protect signal sticks to GND right after reset.
Maybe this also a hardware issue. I'll find out soon
The bricked IPL-bootloader could also be the cause.
At least if the red light turns on, the DC-DC converter on the hermes is doing well. This means the unit is partially working but not booting.
....nearly forgot to say, that there is also a fuse on the hermes mainboard.
should do some pix
Cheers,

Dead Hermes...need help

My Hermes just died today. No type of LED while charging even without the battery in. I was wondering about switching the fuse off of the motherboard (A solution I found after some searching through the forum). Where do i purchase the fuse? any suggestions? has anyone ever done the switch before?
I have some experience with motherboards and I have opened my Hermes before (once for an LCD swap, once for a keypad problem).
Thanks for any help in advance!

Unless you are pretty experienced in surface mount soldering and electronics, you will probably fry your Hermes.

Vibrant T959 Only Turns On With Charger Connected

I have a Samsung Vibrant T959 TMobile US with 2.1-update1, Baseband T959UVJI6.
The battery is fully charged, it registers in the phone as fully charged 100%, but when I hit the power button I get a progess wheel that gets stuck, then the phone just turns off. It never gets passed that wheel, it only displays for a second then dies.
However, when I plug in the USB and hit the power button, it comes right up like it should. Then I can unplug the usb and use the phone just fine. Its almost as if I need to jump-start the phone with a power source.
I have reset the phone, even re-flashed the stock firmware using Odin. Same results. I have even swapped batteries with a buddy just to see if that was the case, but I still got the same results.
Any advice or suggestions is GREATLY appreciated. Thanks Very Much In Advance!

Anybody? Any ideas?

Well, that is new to me...
I'll preface with, I have no clue how/why that is happening. But, this is what I would do:
1 - If really opposed to rooting, I'd call T-Mo / Samsung and get a replacement.
2 - If I liked my phone and wanted to make it better, I'd root it and flash a custom ROM. It likely would take care of the issue, as it clearly is not a hardware thing (well, I say clearly).
Worst case with #2, ODIN back to stock and then do option 1.

possible solution
also it says "USB connected" even when cable is unplugged? I had similar problem.. I tried everything, flashing, changing batteries.. none of that was useful. Then I find some post on some forum that says it might be corrosion, so i scratched my USB with thin wire and everything worked fine, but also scratching USB I was doing one more thing. In my opinion, I think that it's not corrosion. I think that USB is slightly bent (middle part of it), try to bent it in other direction, possible that it's too close to edge. That solved my problem. Tell me if this helpful for you, sorry about my english

i think i can get what you are saying, cleaning the usb port on the phone right??
BUT how does this affect turning the phone on?? if usb port is rusty, it will only affect charging, not turning the power on?

I experienced this identical issue last fall -- the USB would always say it was connected, wouldn't startup unless connected to actual USB, but otherwise worked fine.
Take your phone apart and look at the solder joints on your microUSB port... mine all had cracks in them or had broken free. I re-flowed the solder while holding the port down and it resolved my issues. (put on some flux, and run a hot soldering iron across the joints, clean up... it's not very difficult. just be sure you don't short out any of the pins.) I also added additional solder to the four points that just hold the mircoUSB to the circuit board. It's been rock solid since

See if there is a TV or electronic repair place still in business in your area. Or post an ad on CL asking someone with knowledge and skill to do it. Be careful they aren't an idiot just wanting 20 bucks and happen to own a soldering iron.

you could see if Cell Phone Repair/ is near you and describe to them what you want to do.

I would go through these guys they are top notch helped me when i soft bricked my wife's phone. He even convinced me that i could fix it myself when i was ready to send it to them for a jtag.
They can replace the usb plug if thats the issue.

I would test to see if my battery is bad first before i went about resoldering, it could easily be a bad battery.

[Q] Charging ways - Charge jumper

I have a OnePlus 5 with broken usb-mic connector on the motherboard (FPC). I'd like to restore the charging functionality and, at best, also the usb (data + data -) line. There is a schematic for the FPC pin assignment? There are other place on the board where I can find 5v,gnd,data+,data- line (maybe a jtag or a service hole/plate)?
I also have a spare connector but there's not enough space to re-solder and some plates are gone with the broken connector, so I'd like to find an alternative way.
Thanks

Honestly, resoldering would not help, and since are pretty much left with no alternative but burn chunks of money, I don't know what you expect from here?

I can't understand what You're talking about.
The question (I suppose in the correct section) was easy: There are pins or plates (except the fpc connector) on the OnePlus 5 Board to power it?
For the pourpose I have in mind (a Tasker bridge device) the solder solution would be great, if possible. Seems strange that in the whole board there's not an alternative +5v and a GND to power it. But, after a week and with only Your (non contributing) answer I think I have to get the circuit tester and route some points myself.
I'd rather prefer no answers If the only one I get is about the circumstances and not about the point.
Thanks anyway

Sorry to say if you see it that way. I know what I wrote was correct, and I was just resonating your point that there is no way out. Not sure if you seem to have seen it differently and rather why??

There's always a way out, maybe it could be difficult or expensive, that's not the point. We're talking about a connector, not a more complex component.
Banally, the first way is by following the 5v from usb cable to fcp connector, (as described in a youtube video about OP5T) and check if that plate is still there, then, if not, if there is another point of the same line or a scratchable spot.
The question was about existent schematics and/or other people experience about this or similiar. Things that can make everything easier or confirmed.
So:
- The "repair" is achievable? Absolutely Yes if the fpc plate is not damaged (by making a bridge); probably Yes if damaged.
- The "repair" makes sense? Yes, for my purposes
I can't see Your point and Your statement, as I already know there's a way (that I've asked to be confirmed or already experienced) .
