QI charging

I wanted to share my QI wireless charging project, I had a small turn/twist while doing it.....
I am using a BLUBOON (Make sure it's TYPE B and not TYPE A, found it to be the best one out there, but more expensive $20ish) and an LG G3 NFC + QI but the QI part does not work, it must be some special kind of charging coil? Anyhow, I just cut off the center and contacts from the QI section of the LG G3 sticker also put a piece of cardboard behind the contacts so they would actually reach the pins and on the BLUBOON I cut off the microUSB plug and soldered the + and the - to the USB port. Nicer and cleaner solution than what I had in mind (soldering the 2 pins of the LG G3 QI to cables and running them down to the USB port, making the back undetachable...)
Here is my original post on the OnePlus forum:

So can you use the wireless charging or not? But does look nice anyhow!

LOLZ! Isn't it that the idea? Confused... J/K! Yes, it works.
Here is a pic, I guess I forgot to post one .... Honest mistake!

You should post your results in the wireless charging thread i'm sure they would love to see your setup

Feel free to post a link to the thread in the wireless charging thread.

Hi m4f1050,
LG G3 only has the antennas on the sticker, the NFC board is inside the phone (as usual) and also the Qi board (usually in the sticker for other brands such as Samsung !). That's why it didn't worked.
Take a look at mburris mod : http://forum.xda-developers.com/showpost.php?p=57765939&postcount=235
I think it's rather easier that way
Anyway, good job and thanks for sharing !

8 soldering points vs 2 soldering points ... IDK if it's "easier" but hey, 2 options! I also get +400 mA with my setup. At 25% it said it would take 6 hrs to fully charge..which is half of what a 2.1 amp wall charger (3 hrs to fully charge on 25% batt) Tested both ways.
EDIT: Here is a quick snapshot of my charge mA's (I've seen 400+ but today at work I only got up to +375 maybe it's the wall charger vs the one at home....)

Here is my OPO on my home charger. Its a Trident single dock. Ordered the dual dock for home and took the single one to work.
IMHO the Chinese docks (black or white with the wireless symbol in center and a red on and blue charging lights) aren't as great...
BTW I downgraded back to 4.4.4 since 5.0.2 was draining the phone more in idle.

damn.. i cant solder worth SH!T.. so this wont help me.. lol

I did the soldering because I wanted the USB available, but you can get the generic charger that plugs into the USB port then you put the lid over.
It's how I first started with QI on my OPO. Just make sure you get --TYPE B-- instead of --TYPE A--
Type A: narrow end of micro USB upward.
Type B: narrow end of micro USB downward (what we have on our OPO's)

Check pics. I cut off the USB plug and soldered it. But originally it was a BLUBOON generic QI charger (type b)
If you are soldering you can use TYPE A but you have to inverse + and - before soldering to the charging port.
EDIT: Attachment shows QI charging from 77% to 100% in an hour and a half. Almost 25% in 1.5 hrs. So around 6~7 hrs from 0% to 100%

USB Type-C's connector is designed for many many cycles of use. It's supposed much more durable than Micro-USB, so it should be fine.

Probably because you don't try jamming it in backwards half the time.

I doubt LG bothers with that. They just chuck the broken unit in the trash and send a new one. If you mean some mall kiosk/street vendor/fly by night internet operation, then yes, that sucks for them.

Looks easy to repair reminds me of my iPhone 3gs. It was 24k jailbroke for life I replaced the battery and speaker in it

Hi
Interesting it has 3 microphones, there is one top and bottom (externally visible by the small holes top and bottom) plus one on the earpiece.

Without that you can't use touch screen.
Just google for the string "MANTA GT-P8110 GT-P8110KTL" or just "GT-P8110KTL" that is the cable component number.

Unfortunately the cable from both links you provided is incorrect. I have seen them before, and it looks like an LCD cable based on the color, shape, and the model number on the pictures.

Bought new battery from amazon-newnet
I had to place again old Battery as new one collapse at 40%
doing that clip broke and now....

Same here! Any part source?
I did exactly the same thing replacing a battery. I found someone local to solder and bought what I thought was the correct part (https://www.parts4repair.com/45pin-lcd-fpc-connector-for-samsung-google-nexus-10-p8110-2pcs/). But alas this is NOT the correct part. This is for the LCD flex cable not the digitizer.
Anyone have leads on where to source the correct connector?

Leeco pro 3 x720 Burned USB connector

Hi Everyone!
Unfortunatelly My x720's USB connector burned few weeks ago during fast charging.. It is burned, the connector is fuzed and I feel the burning smell, but it was already too late.
So the usb port got unusable, I can not use it for charging, and I am not able to connect to my phone!
I wanted to buy a new USB flex board but unfortunatelly there is no full (factory) version on the market!
I searched it many hours on the net, but there are only cheap ( remanufactured) version of it.
They have many missed parts, just have their solder points on the board, so these do not support OTG and fast charging.. I can not understand why can't make full version boards for a higher price, these versions are unhelpful items.
https://ibb.co/kYypx8
https://ibb.co/fnH4VT
https://ibb.co/fZM9x8
So I bought only USB C connectors and I will try to replace it on the original board!
I thing it will be a hard work, but I hope it will succeed.
If not, I have to buy a used phone for parts, and I will take out the USB board from it.
As I see, the X722 have the same flex board!
So I would buy a hard bricked x722 for parts for a good price!
Just very important to me that its USB connector be in a good condition!! Do someone would sell it??
I know unfortunatelly there are lots of users who have hard bricked dead x722...
So if you read this lines and you can help me, please write me, and I hope we can make a deal!
Thanks
Daniel

Hi, exactly the same happened to me, the USB port of my leeco was burned. I do not know if it would be because of the usb cable c stock that brings (bad quality). But you'd be surprised if I told you that, shortly after the usb port c burned down, I looked more closely at port C and there was melted black plastic on the pins of the connector. Then clean the connector with a fine needle (carefully), getting rid of the plastic, the remains are cleaned with cotton and a little isopropyl alcohol (which leaves no traces when it evaporates). After doing all the above, I was surprised when I plugged in the headphones and it worked, in the end I tried another cable type C first with the PC and it worked (it was recognized by the normal PC), then I took a chance with another charger I had at home (not the Leeco charger) and it worked ... I had no problem loading it. You could try it ..!

Hi
@Kener97
Thanks for the response, I would try it, maybe it would work for me as well, but it is pretty melted..Unfortunatelly I have already disassembled the phone. I did not have another cables, but now I have two good quality fast charger USB C cables, but now I already can't try it! I happy that you can use your phone after the accident. Yeah, you're right the original cable has very bad quality. I had already thrown it into the trash.
So I decided If I have already disassembled the phone than I will try to replace the USB C port in the next week and then I'll se what can I do.
@tsongming
Thanks for the links, but as I wrote, these USB boards unfortunatelly are not the original items just cheap versions with many missed parts! Check the images!!
You can see teir solder points on the boards. So these don't support OTG and fast charging... Only the normal charging without communications. These are not an option to solve the problem. Maybe if I would replace the missed parts from the original board if the connector replace won't be suceed.. )
I will write the result!
Anyone, any other solutions? Or anyone known where could I buy the factory version boards?

Thank you for the answer. Do you think the problem is the whole charge or Just the cable? Is It ok to use fast charge with third party cables?

The cables are notoriously bad, one of my x727s was destroyed by a bad cable. Fortunately, Amazon exchanged it for a new phone.
We have 4 Leeco phones in our house. I have replaced all of the USB cables with highly rated cables, that have a replacement guarantee.

Although some people recommend also switching the charger block. I don't agree with them, and think that is overkill. Its the stock cables that are garbage, not the the charging blocks.
We have four of these charging blocks and no issues with any of them. In fact, in late December, when the X727 that I returned had its usb card burned. My dad ( a retired electrical engineer) took apart one of the blocks and found it well constructed.
Next, Leeco charging blocks are approved by and meet Qualcomm standards.
https://www.qualcomm.com/media/documents/files/quick-charge-device-list.pdf
If there was an issue with the charging blocks on a large scale, would they still provide this publicly available list? No, I don't think so.
Should you decide to go ahead and replace the adapter anyway, The pdf list has a section with Qualcomm approved chargers under the "Premium Power Banks" section

There are plenty of people with bricked X722's, go to the X722 unbrick thread and message those people, maybe some on will sell you their expensive paperweight for cheap.
If you live near a large city there is bound to be a shop that does repair at the component level. perhaps they could fix your damaged board or as you mentioned transfer the chips from the old board to the 3rd party board that has missing chips. The issue is that some of those chips are likely fried.

Hi!
No, only will work the slow charging and USB communication with the cheap, useless USB flex board!
But there is a solution, to get a new original x720 USB board with all functionality!
After 3 months and Iots of time what I spend on the net, I found TAOBAO chinese site, and to my surprise some seller selling the original version board there with a good price!
Use the Crome browser with built in translater!
Only one problem, TAOBAO is a chinese "domestic site", and nobody ship to abroad.
But I did not give up! And I found the final solution, that's Yoybuy! (Yoybuy.com)
Yoybuy is a forwrding site!
You can buy everything form chinese sites helped by Yoybuy, for a cheap price!! From Taobao or many chinese site and you can use it English.
Just register at Yoybuy and copy the Taobao item's link to Yoybuy and they will buy the items, what you want! You can pay by paypal as well!
I hope I could help you! My phone is back to life, and it is like a new one!
Regards

I think you make a good point about the the LeEco charger. Precisely, it is the cable that is the biggest culprit. I recently bought a x720 and had it for a week charging with an old charger and cable of my le 2. One day i couldn't find the le 2 charging cable so I decided to use the one that came with the pro 3. Just seconds after plugging the cable in I smelled burning plastic and could see smoke coming out of the usb port. I removed the cable and could immediately see that it had melted on the pins close to the edge. Funny enough, if i plug this burnt cable on my le 2 it is charging but if i plug it into the pro 3 it gets hot and starts to produce smoke. I have tried with other type c cables and the port is burning them also. Now it looks like I need to replace my usb port. I will have a closer look at it to see if it can be cleaned but I'm not hopeful. I hope i can get original parts for it because i was sold an old phone by an AliExpress seller who claims it's new. I have started a thread on it. Hopefully I can spin it out to ask anyone with information about where to get genuine parts to help restore these old phones.

usb port replacement? fire hd 8

Hi All, I have the hd 8 , bought it August last year for my kiddo, today tab is not charging, looked at the port and i can definitely see something bad happened, like kiddo pushed the cable other way round, anyone did replace their ports? Is it soldered on the main board? Would it be hard?

Hi I've not personally replaced a micro usb port on the kindle fire but I have done on other devices before. You would need a hot air station to remove then re-solder a new port onto the board.
If you take it to a computer /phone repair shop I'm sure they would do it for you

usb port is very weak on those kindle fire devices. partially broke off on 7 and completely broke off on 8. it actually broke off from the bracket which is suppose to hold the port itself to the board and of course those 5 pins did not live long after that. basically get a magnifying glass, very thin soldering tip and search youtube for HD8 disassembly. the fix seems to be easy, actual soldering - not really )
