Broken Battery Connector (Dead Phone) - 8525, TyTN, MDA Vario II, JasJam General

Long post, sorry.
Phone slid off the couch, hit the floor, battery door popped off, and afterwards if I moved the phone while on a call or slid the keyboard out to type it would just go black.
A light shake and it would die. So I popped the battery out and took the back cover off. Inside, the black battery connector (I can post a pic) was half attached like a loose tooth.
Took it to a repair shop, the guy was great soldered it back on but said it probably wouldnt charge cause a line on the main board broke????.
Phone doesn't seem to recognize the battery. Red solid light when plugged in, no amber with the battery in. Wont turn on. Anyone have any suggestions or am I looking at a brick. Does anyone on this board do repairs like this?
Its a Softbank X01HT from ebay and I flashed it to Mobile 6 so warranty is pretty much out of the question.
Any help would be greatly appreciated.
Thanks,
Fredrick
PS, I'd make a suggestion to anyone who's battery moves around inside the phone to wedge it in place so this doesn't happen to you. We don't hear of this happening often(or ever) but it happen to me, I suspect its because the battery has a little bit of room to move.

May get a chance late tomorrow to see if there may be a work around. This is not an easy board to work on though. A pic of the "broken-line" would be most useful if at all possible,
Can we assume, the black part you refer to is the part with the gold battery connectors at the bottom of this photo?

Thanks for the quick reply Mike.
While it was off he showed me the bottom of the connector assembly, where the broken line is.
Red arrows are the 6 solder points
Blue arrows show the line.( I think, I'm not 100% sure what a line is)
How this helps clarify.
Thanks,
Fredrick

Well sadly, having looked at the board, I think the guy who soldered the connector back on, did about as good a job as it is possible to do. It appears that the connector block contacts (two of them) have broken off the board contacts. With a crude board you could simply trace back to the break point and solder a wire from the board to the connector. However the Hermes usesa multi-layer board that means it is impossible to trace back to a point just after the break.
Unfortunately then, unless there was some of the board contact still showing, you cannot solder short wires to join to the contact block With a detailed circuit diagram you might be able to identify alternate points to solder a couple of wires to link to the connector block. This though is such a remote possibility that you can virtually count it out. I do not know of such a diagram that is publically available and manual soldering on this scale would be almost impossible. If HTC were asked to repair this board, they would just replace it.
Sorry!
Mike
PS You didn't say whether it worked normally after the repair and before the battery ran flat. If it did, you could in theory charge your batteries in a free standing battery charger, but I doubt it would be worth the hassle.

Our solder friend suggested the same, but the phone doesn't recognize the battery being connected. So no dice, its a brick.
Anyone want to buy a white case with a front camera. Or better yet, can I buy a board for it somewhere?
Thanks again for a your time Mike.

main board problem? please tell me its not.

hi! i have a dopod 838 pro. and it suddenly cant turn on. i was just texting then it went buggy (hanging up) then i did a soft reset then all of a sudden it didnt turn on. i was charging it at that time.
the phone never got wet, was never dropped. i installed the official wm 6.1 rom and it had been running for more than two weeks so i dont think the problem was the ROM. battery is good since i still get two days of battery.
i have tried hard resets, used the usb connector to power the phone up. i had this sent to the authorized htc service center, they tried another batt and charger but still nothing. i was told to leave it for 4 to 5 days...and after the wait i was told that the main board is the problem. and replacement is not an option since it would cost me twice the price of a second hand unit.
this was an observation: when i remove the battery and connect it to the charger, LED is red then it disappears when i replace the battery. no amber going.
is there still a fix for this? the service center does not perform any board level repairs. if this is a battery connector problem then a little soldering might fix it right? i hope i can still revive this. thanks!
a little help please! more power to this forum. thanks!

The Hermes mainboard is a multilevel board. If the problem is a broken connector inside the mb then theres no hope. So saying, look at the connectors. If you see a break you can resolder and maybe have a bit more life yet.
Cheers...
ditto ultramag69.
Breaks in the connections below the board surface are virtual death to the motherboard. you could in theory put in jumper wires but you'd need detailed circuit diagrams and suitable solder points. However it may just be the surface connections of the battery connector block and these can be re-soldered. Here's a pic of the board with the block de-soldered;

However, before going to re-solder you could just check it's not a poor contact between connector and battery (I doubt it is, but you never know). To test this out try this:
You could also press on the connector a little while you power on. if this worked you could be fairly sure it's either the soldered connections or a crack internally.
Now if all of the above fails, you need to be aware that it could be a number of other things. A fault in the usb connector or damaged connections on the USB to board joints. Conceivably it could be some damaged caused (hairline crack perhaps) when you inserted the stylus in the reset hole. possibly even a damaged reset switch stuck in the on position etc etc. Any of these things would really require test equipment and even then without suitable data it would be difficult to diagnose.
good luck

Hermes odd battery problem

Hello, I am having an odd problem, I can get the phone to turn on, charge, and watch youtube perfectly. All this can be done by wedging a mini sd card in between the battery exact opposite of the terminals. What could be the problem of this? No sd card, just did a hard reset, and using the oem ac charger. If I pull out the mini sd card the phone shuts off, And if I connect the charger all I get is the solid red light. I am comfortable taking it apart and have all the correct tools.

You have really answered your own question. You have a pin that is not making good contact with the battery. You can clean the contacts, but that may not be enough. You can try bending the contacts out in the direction of the battery a little. However if you do this you run the risk of cracking the solder joints between the contacts and the motherboard. So, as a do it yourself solution you can do this:

Alright, If anyone is having this problem I just fixed mine for good (I hope). The points where the battery contacts and mobo meet were cracked apart, thus making the phone work when something was causing the battery to put extra force on it. All I had to do was remove the mobo and solder them back on. Took 30s for all 6. Now it comes on and works great no matter what.
I had the same problem a while before I realized it about six months ago, on the same model as yours. I then realized what you did, the battery wasn't contacting well, and I whipped out a business card, cut it to size, slapped it in with the battery and viola, no more strange power losses. So you say that the solder points were cracked ehh? Something I will be checking in about 2 minutes, don't doubt Thanks for the tip!
UPDATE: Took it apart, and couldn't see any place where the pins have cracked. Seemed solid to me, even under a magnifying glass. Did you somehow take the black protector off of the pins and find it under that? Thanks for any info you can send.
Mine was cracked between the mobo and pins, Test it with a multi-meter for resistance, It could be cracked or weak but you can't see it.

himalaya alternate chargeport?

My himalaya's usb/chargeport has been completely ripped off its motherboard. I have to externally charge battery.
however, i got to looking at the thing and i saw a weird jack on the back that looks like its the same pinlayout.
whats the purpose of this port?
I'am looking for that answer like 5 days! I searched a littke over net and i think is called CF backpack jack! Check this link http://www.theunwired.net/?item=rev...backpack-for-himalaya-pocket-pc-phone-edition
And i think that phone can't be charged over that jack. If i am wrong i would be glad to someone confirm that!
If your connector is in one piece (without broken pins, pins 13, 14, 15,16 and 22 are for usb and charge) u can take it to local gsm service to get it solder back for u! If is not, u can use alternate miniUSB jack, there is thread in this forum how to do that! But is ugly to see a small connector that peeking out of phone like a mouse!!!
well if the cfbackpack cna provide power over the power, youd think you could charge from it.
well we can use a any broken one and pull out a connector and solder a cable for it!? But a problem is where to find a broken cfbackback these days!?
i don´t know of any shop who sell this part,dood!
there can found very,very rarely on Ebay my friend !
So, the general advice for all those with broken himalaya connector (depending of what parts are broken) is alternative miniUSB OR, buy an universal charger for charging the battery

And for PC sync use bluetooth USB dongle (i am not so happy with these solution, cuz my hima don't hold battery much time and when use this dongle it won't hold battery at all, especially when transfer to many data)
And for flashing a new rom, we can use a SD card, but still needs a USB cable for taking a header from bootloader http://forum.xda-developers.com/showthread.php?t=482236)
soldering anything on that motherboard is a real sob, the pins are bloody tiny=
Yes i new that, but that is a job for a service guy. I took the draw and scheme for what pins goes with what (for miniUSB) and took the phone to him and he do the solder job with his super thin Solder Iron and that job costs me a 3 euro. He finished the job in 1h and 15 mins.! It's forbidden to people who don't know anything about these things to take any steps alone. Consult with some gsm service first, instead to do something wrong and destroy the phone board pins and the connector!!! These connector is a general problem! After 1 or 2 years of use, almost every Himalaya will have this problem!!!!

USB connection physically dead; not charging or usb to pc connection

Hi everyone!! i'm desperate since i think i came with an expensive, unusable phone in my hands.
I read and searched thorough but there doesn't seem to be much clue on this, just one or two lost threads....
Someone care to drop a hint to help me ? ive lost all hopes.....
My x10a, after using it for , say, 1 month, rooted with latest xx23 firm (and used for a week or more , perfectly fine) ... some days ago, it stopped recognising USB port.
IT does not charge, with no existent charger or usb cord; it does not recognise usb connection of any kind, to any computer possible.
It lasted till last battery charge died, and no way to resucitate.
Afterwards, i came up with something: i bought a crappy, chinese battery-charger, drop my X10 battery overnight, and the phone then booted and worked fine.
So it is the USB connector/port/circuit. I even though of reflashing or re-rooting, but you can figure out that i can't do that anymore (no usb :S).
I can't give it back to SE or seller since it was brought overseas, and it even has some little marks on the corners (they'll just claim i dropped and so).
Any caritative soul please?
I opened following McKebapp guides, but didnt find nothing in particular.
Do you think i should risk in getting hands dirty and, say, re-solder an usb jack?
If not, i offer in sell all spare parts, almost new, or even sell it at a very good price, e.g. for bootloader experimenting....
Thanks !
Are you sure there is no gunk in the port or the cable's contact itself? Or even a bad cable?
Try this.
(1) Buy yourself a can of contact/electronics cleaner spray.
(2) Remove battery from phone to ensure you have no power going through there.
(3) Spray area clean and wait for it to dry.
Afterwards put battery back in, power up and plug in. See if that works
Yes, i tried all these... but nothing... Of course, i tried using up to 10 different usb cables, even bought new ones... but the strange thing is that nothing really happened, in order to mess or 'break' something on the phone...it was from one day to another... strange....
I wonder if the port is soldered to place on the board or is just spring contact based. I believe Bin4ry had his phone disassembled - you can ask him. If it is spring loaded contacts - there might be dirt underneath that needs to be cleaned up. If it is soldered - a joint might have broken and need resoldering.

OMG... NEVER do that to a PCB with BGAs...
You'll shorten the connectors underneath the BGA soldered chips by fluid that stays there thanks to capillary action.
@rodrigofd:
Here you can see the USB connector itself, on the very left side:

IF there is any mechanical failure, one or more of the five solder points in the middle of the connector is loosened.
But I can't believe it's a mechanical / solder problem.
Wiggle the USB charger cable a little, while having it plugged.
That way, you'll determine if there is any hairline crack.
If there is any, you can think of resolder it..
If you ask me, I'd say, some SMD fuse has blown up or there is an hairline crack between the PCB layers.
To determine that, you'll need a 3rd level schematics and some electric circuit reading knowledge.
If nothing helps:
Wait till there is a OTA Update that unroots the phone.
Then bring it to service..
The same thing happened to mine. While it was charging on my desk, and I was asleep.
I woke to find the phone on the floor but the USB cable was attached.
Using JuicePlotter (which had been running) it seemed that the phone had stopped charging around the time I had missed a call.
My detective skills allowed me to deduce that the phone was fine, but then when it rang - and started to vibrate - it rumbled its way off my desk. I believe it was not hitting the floor that damaged it - it's carpeted and not much of a drop - but the shock to the USB cable port as it swung itself off mydesk, effectively "hanging" itself.
I'm afraid I had no luck fixing it but it was only a week old so O2 replaced it immediately.
These days I ensure the phone is FIRMLY wedged somewhere when charging it.

Retrofit Wireless Charging Receiver in Nexus 5X?

I just saw the iFixit teardown
https://youtu.be/VYFbSpvSE-w
I retrofitted a Galaxy S5 and S4 to wireless charging with Qi receivers off of eBay:

I know there is one for the G4 (since it's in their flip cover), but I was wondering if it is possible to work with an existing coil and wire it up to the Nexus 5X.
First, the cover pops off like a Galaxy S5 cover:
Here is the back cover and internals. Normally, the NFC covers the battery, but I am thinking it might be above the camera since there are connectors from cover to internals and would make sense for Android pay. So, what is the big shield on the right that covers the battery? (see question mark):
I think the battery posts are under the white piece of tape on the right - easy access for an NFC receiver to charge:
Worst case, the battery contacts are accessible under the midframe (10 screws):
So, do you think a retrofit of an existing Qi receiver would work? (the NFC part might be not used). The shield on the back over the battery might have to be removed, but I am not sure of it's purpose. Alternatively, anybody heard if any company is making a Qi receiver for the 5X? I'd buy the 5X over the 6P if I could get wireless charging.
I guarantee it's do-able. I don't know if the battery fuel gauge contains the logic to simply solder the coil output directly to the leads going to the battery but it shouldn't be a problem to solder to the VDC/GND pins/traces coming from the USB port. The only thing that concerns me, and I'm saying this w/out having looked at how USB c accomplishes it's reversibility, is that the pins for power aren't achiral (for lack of a better word) depending on the orientation of the plug. Would need to read up on that.
Just saw another thread opened shortly after this one was posted:
http://forum.xda-developers.com/nexus-5x/general/nexus-5x-qi-wireless-hack-mod-t3231461
Guess I had the right idea , but the video shows only the teardown, no connection.

The NFC antenna is around the camera, you are correct on that. That foam material, I'm guessing that is what it is, is there to fill any gap between the battery and the back case to avoid the back being able to press down, and being soft it works with the varying differences in tolerance with the the battery thickness. It could even be to fill a recess that was suppose to be filled by a wireless charging coil.
Notice though the foam continues up to the site of the fingerprint reader. That should remain, it's job is to apply pressure on the contact pads of the flexible circuit board.
In the video where they show a mod, what they have done is used a QI coil which has it's own circuitry which outputs 5 volts, this connects by thin wires to the +5v and ground of the USB socket, and from there goes to the battery via the normal charging circuit, the phone doesn't know it is wireless charging, it just looks like a USB charger is attached. This direct connection may cause a problem when plugging in a normal USB charger as you end up with 5 volts in reverse going into the QI circuitry and charger, presumably though that circuity is protected with a diode so it doesn't matter.
You shouldn't connect anything directly to the battery terminal as this will bypass all the charging circuitry and would cause damage and likely trigger the batteries protection circuits and cut it dead.
How cleanly the back refits is another thing, their can't be that much space.
Regards
Phil
