Turning the A100 into a A101

Call me crazy, but I've soldered a mini pci-e connector into my A100. Unlike the A500, it looks like there are few missing components. I mean other than the pci-e connector and the SIM socket, there are only a few missing components. And when I do trace those missing components, they don't seem to trace down to the pci-e socket.
So at this point, I am waiting for the sim socket to come in from ebay. I couldn't get the exact piece... at least not based on the pin-out I could see on the board. So I've got something coming I hope will fit.
I've also got a huawei em720w coming in with 3g antenna....
In the mean time... here's a pic.

can you give more details and put more photos I am thinking of doing well
I see you are a restless soul
greetings and thanks

Not much more to say at this point. I used this guide: http://forum.xda-developers.com/showthread.php?t=1297422 to open the A100.... Believe it or not (mostly not), I had the pci-e connector in my parts bin...
The pads were solder shut... had to open them up with solder braid. It was pretty straight forward, but I am VERY comfortable soldering. And the pci-e connector is a difficult part. That`s a warning.
When I was doing my beep tracing for missing components, I used this guide http://www.allpinouts.org/index.php/PCI_Express_Card_and_PCI_Express_Mini_Card#PCI_Express_Mini_Card to help remind me of the pin out.
Other than that...

Take it slow...

thanks for the time being will continue its progress

Looks like the end of the dream. I found the missing components hidden under a piece of tape. I not sure all of what is missing, but it looks for sure like the voltage side of the sim card slot and perhaps the usb controller for the pci-e slot.
So I'm going to put this one to bed for a while. The a100 is very easy to open and I'd be interested in revisiting this project when we have an actual a101 to make comparisons with.

may be 3G model is huawei770w

How to add NFC support to battery?

Hey, I have a fake battery bought from eBay that looks exactly like the original one but it is fake.
The problem is that it doesn't have NFC support. NFC works fine if the original battery is inside.
Since the battery just acts as NFC antenna, maybe it is possible to out something conductive to touch the correct contacts and NFC will work.
Did anyone ever try that? Does anyone know how to do that?

I searched around, doesn't seem like nothing what you are suggesting has been done; Also, no hits on Google;
I would advise you to simply buy a NFC-capable battery. Messing with li-on batteries is not a great idea, IMO.

But that's not FUN
I'm not going to mess with the internals of the battery, just create an antenna that happens to be glued to the sticker of the antenna but could really be anywhere else.
Update: I did it!!!!!!!!!!!
Pins 1&3 are power, pins 2&4 are NFC (1 is leftmost pin)
I connected a bit of copper wire to each of the NFC pins, and connected them using coil (wrapped 4 or 5 times).
It reads NFC tags very well, the only problem now is I can't close the back cover because of the giant coil. I'll try to find a solution to that and upload pictures (or video), because as we all know "pictures or it didn't happen".

Update: The project FAILED.
I tried to connect the two NFC pins using a coil. When the coil was away from the phone, it worked very well. When the coil was on the phone, it didn't work. Since I wanted to stick it on the battery and be able to close the cover, I must say it didn't and can't work.
The fake battery is blocking NFC signal. If you put the good battery in and then put a tag -> NFC success sound.
If you put good battery in and a tag+fake battery over it -> No sound. Take the battery-> Success sound.
That concludes our experiment.

Real Samsung batteries with NFC are available on Amazon for $8.

+expensive international shipping. I'll stay with one battery that does NFC and one that doesn't, until my next phone.

I'm considering attempting to remove the antenna sticker from my old battery, stick it onto my new third-party battery, and connect the leads to it's pads. Will update if it goes well. Or if it doesn't.

Welp, that didn't work.
The nfc sticker on the stock battery seems to fall apart if you try to peel it off.

Headphone socket not working

Hi All,
Im sure I can't be the only one but is anyone else having a problem trying to get sound out of the headphone socket?
Any searching I have done shows a similar problem on the M8 after a firmware update.
I have had the phone less than 24 hours and have only transferred my numbers etc across with the HTC tool.
Im currently on 1.32.161.15.
The socket works as I am able to force the audio to it with soundabout from the play store.
Any help/advice appreciated.
Many Thanks
Aggi

I'm still on 1.32.401.15 and no problem at all with the headphone socket tested with the earphones came along with the phone.
And wow what a sound, normaly im using my bleutooth headset and never use in ear phones but wow love the sound

Thanks for the info.
Ive been out all day and was using my old headphones that came with my sgs3.
Just tried the supplied ones and they are indeed recognised by the phone.
Sorry to have started this over what seems nothing and thanks for your help.

Headphone Jack stopped working
Hi. My headphone Jack just stopped working. I had this problem on my m7. Didn't expect it to still be an issue on the m9. Any solutions out there?

Clean the connectors this usually fixes most issues, fluff getting stuck in the hole is common and causes the most issues

The similar case happened to me once when I updated my M7 to a new Android OS. The phone still couldnot produce audio even I changed two new earphones, I was thinking about replacing the headphone jack. The problem solved the other day when I accidentally turned on the volume button! It's not about the headphone jack, it's because I turned the volume off! Well, that's really a shame.

HTC One M9 Sound Not Directed to Headphones
Hey,
My headphones aren't working. I just woke someone up! The sound is coming from the phone. I tested the headphones. And the phone acknowledges they are plugged in. Help?

Headphone socket [SOLVED]
First of all im taking credits cuz it wasnt me who came up w this idea.
1. Plug in your headphones ALL THE WAY IN
2.immediatly pull it out(just a little bit you will notice)
Repeat these steps until you see the icon pop up.
Works with m8 and m9 so far

Hi,
My phone recognizes that the headphones are plugged in, and the icon shows up for them. However, there is still sound coming out of my phone, although it's muffled. I thought it might be a problem with the headphones, until I tried them on my other devices and they worked. I'm not sure what to do.

Just get a paper clip or other stiff thin object and push in the pluck out the debris if any from inside, pocket lint can stop the headphone jack from going all the way in, you'd be surprised how much can come out of it.

I'm having a similar problem, but it's earphones WITH a mic that don't work. Otherwise earphones without a mic seem to work just fine.
Any suggestions?

Clean the fluff out of the socket. Then you wont be able to see any of the plug when you plug it in!.

Resistant SWC Problems - 3 wires at car, 2 at HU

Can anyone confirm that these units work with other mics? I plugged in my Kenwood Mic but people can't hear me at all.
Also, my car has 3 wires for the swc, swc1 swc2 and swg (I think for the ground). The radio harness only has 2 wires, will the buttons work if I only connect 1 and 2?

I'm wondering the same thing. I can't get mine to work. Currently I have the 1 and 2 conected to the car steering wheel wires and the the ground to other grounds. It doesn't work. It's a Chrysler 300 if anyone knows.
Great rom, I'm new to these Chinese decks only have had it a week so I've been trying to read through the thread before I ask dumb questions. Lol

If you dont have swg, try swc1 from the car to scw1 to radio and scw2 from the car to ground? Also you can swap swc1 and swc2. Make sure you document what combinations you have tried.

Regards mics, almost all PC and phone mics will be the electret type,and will be able to work across systems. They consume tiny amounts of power and are fed a small offset voltage on their signal lines. Usually 5v but can be all the way down to 1.7v The most likely reason your Kenwood wont work is the plug/jack layout. Correctly wired the mic should have signal on the tip, and ground on the shield of the plug. Problem is even apple and android standards for this vary, and plugs have been introduced with stereo headphones and mic on one cable i.e. four connectors in the jack. My head unit ext. mic jack came with one of these, even though it only wired up one signal and ground. Try a mono to stereo adapter, or a stereo to mono adapter. The best way is to test connectivity with a multimeter, and match signals up.
I just did the steering wheel controls. You MUST have all 3 wires from the car. I can confirm, once you have identified which is ground, the other 2 can be connected either way around and it works fine. If the ground is not connected, and you can ground it anywhere, does not have to be at the head unit, you will get random control results, mine I had 3 working buttons, and 3 dead.

Ok, I guess I'll try using the Mic that came with the unit and hopefully it'll work.
About the SWC, from what I understood you connected swc1 & swc2 to the 2 swc wires on the radio harness, and you also connected your swg to any ground wire (example harness ground) or point you can find.
So after you grounded the swg wire, all 6 of your buttons were working?

Yeah it did but it doesn't mention anything in cases like mine where you have 3 swc wires. It's cool, I'm going to connect the 2 wires and ground the third.

Yes, correct at first I just connected the 2 wires up to the new head unit, on mine called KEY1 and KEY2. Only 3 buttons worked. Then I did a little research on my car, and it was clear the 3rd wire is a ground. Connected and all 6 buttons great.

Danke for the clarification. So what part of Joburg are you from? I've been there many times but usually stay in revonia. I lived in Margate for about a year, it was nice down there.

How to wire steering wheel controls or microphones has absolutely nothing to do with Malaysk's firmware. It doesn't belong here. Take it elsewhere.

Hey Mike, mind your business.

It is kinda off topic but no need to be rude, a simple "you might get more help in the Help/Question/FAQ section" would be more polite, and "mind your business" is also not a polite answer to the comment. It's like throwing more wood in the fire... I'm just saying... Let's all get along, glad everybody worked out the switch control issue. As for messing with something and having issues afterwards, I would suggest to take the car to the stealership (dealership) and have them reflash it, maybe you're lucky and it has a fw upgrade? I've never had any swc control change any settings before though... I know that on my VW cc I have all buttons on the left work properly (6 total - up, down, left, right, phone and voice) but on my F15 most of them work (5 total - vol+, vol-, rew, fwd, media) out of 8 work, because of SYNC, the last bottom 3 don't work.
BTW, veliksam, I noticed you are from Orlando (I am too) are you having issues with the 24-hour not staying off? Or do you have 24-hour on because you are used to it or what? All my units (3 total) the 24-hour turns on by itself half the times when I turn on the car, and I'm used to non 24-hour... This happens on this ROM and I believe even on the stock one.

the sw button is unrelated to this ROM topic and your rudeness is not tolerated here!

LG G3 Boot on charge

Hi! I'm trying to make my old LG G3 D885 into car headunit/ navigator and I'm having trouble getting it to boot while i plug it into the charger. "fastboot oem-off-mode charge 0" didn't work for me and i didn't find lsp file where i could change settings so does any of you know how it is possible to get this to work?
I have gotten the fastboot to work instead of download mode but that is the furthest i have gotten.
All the help I could get is appreciated

I drive my vehicle everyday a lot. 01 eclipse built up a little. So im in it a lot and my battery stays charged. Plus i made my unit removable so if need be i could turn it on or other functions if i decided to take it in the house
