Below the internal structure of the mobile phone watch!
(If the picture has the wrong places on guestbook please! I'll correct!My English is not good)
Polaris to talk about the following questions often arise!
Does not read SIM card! If you do not read most of SIM cards are SIM card connector is broken! Because SIM card connector cable are bad style is easy!
Do not read memory card! For memory card connector of the problem can be solved!
These two questions often arise!
If the handset at the same time. A microphone and speakers or bad, the majority are radio and ROM does not match the reasons for!
If less than WIFI, WIFI antenna to check whether the contact bad! Or ROM problem!
Keyboard part
The keyboard includes a touch screen and keyboard! Problem is prone to rolling keyboard! Rolling keyboard into the dust can easily bad!
CPU and memory are very few bad!
Recurring problem on these!
My English is not good! Expression is not good! Please forgive! Thank!
Sounds like you have a malfunctioning polaris. Try a hard reset or flashing to the original ROM. If neither works, look into having it replaced or repaired.
it's just my problem or the image is missing?

Hello All!
I'm lookin for main board fotos w/o components like this Universal_JTAG, but in better quality.
If you have similar and both side fotos (hi resolution and sharpness or at least in more or less good quality, visible trace circuit board) please share!
Thanks for any help.

Welcome to the forum
may I ask why you need that?
For a more detailed study hardware (yeah... circuit scheme would be better... but I think unlikely to have free access) and deep modding!
For example, there is a desire to expand the memory through the free rooms, sure is achievable! Oh, I would be traced, but found broken universal is problematic nearby.
So, my research has led to some results. I was able to use two flash-cards together at same time. You can use the MMC and SD card only (no 2 MMC or 2 SD).
Stuff at me a few days ago, only to learn it
should help http://wiki.xda-developers.com/index.php?pagename=HTC Universal Service Manual
I saw this, is not it a bit
I am interested trace the following pads (blue mark on photo).
It is usb functions of the proc.
Where you can connect to them on board.
Please, if you know or can do trace...

A'ight, so i opened my good old' Prophet today.
I am 50% sure that the battery thing thangy on the motherboard (see pic) is broken.

However, it might also be the battery, i have two batteries, one is the one that came with the Prophet and one is a cheap battery i ordered from Dealextreme.
I do know that the cheap battery is dead, but the other one (I did some testing with it, it shows up at 1.4V at my multimeter) i'm not sure if it is dead.
The phone has been like this before:
It randomly worked, randomly turned off, it wouldn't work for like 10 days, then when i put the battery in again it worked.
It kept doing that until it died completely.
Any suggestions?
I can't understand on photo. A battery pin is broken? If the problem is broken pin, a watchseller or jeweler can fix it. They have the right equipment to work with small things

You think they will fix this?
I would try to get a new (third) cheap battery.
Or try to re-animate the cheap one (dangerous, forbidden, but works often for me: open battery casing, unsolder LiIon-Cell, reload with Lab power supply to around 3-3.8 V (never > 4.2V!!!!), resolder, put in Prophete, start charging....)
The pins look ok. 1.4V for LiIon is below the deadly shutdown value!

OK, maybe my answer is a bit late...

That was gonna be my reply too... Module might be there but if you are using A500 rom the drivers aren't to control it....
There are a few A501 roms in the dev section, I use Harkon but am going to try Alexandra_II_A501_ver_1 soon...
If the 3G module still isn't working there may be something else that needs fixing....
Try the FCC's website
I've seen circuit diagram on their before so they might have one on the FCC page of the a500/a501
I really think there are a lot of things missing from A501... I've posted a 500 manual in this forum, maybe it will help.
3G retrofitting is a pia, you should try selling the 500 and buy 501...

Are you planing on running the a501 software...?
I have the following problem:
I have bought 2 nexus 4 and combined those two to 1 working N4.
I'm getting complaints from people that they can't hear me to well.
We I put it on speaker they can understand me perfectly.
Would this be a hardware or software issue?
I'm running M915A-CEFWMAZM-2.0.1700.98 hybrid radio and Nexus 5 experience Rom.

The only way you can find out is by flashing a completely new ROM (after you backup, of course) with a full wipe, and trying to call someone. If it works, then it's software. If not, it's hardware.
My take on it is that it's software; microphone is working while on speaker..

Ok, I found the cruelpit.
it was the usb port board that was faulty.
I ordered one from ebay because my port was broken, however it is missing something on the mic.

The bad one doesn't have a black film over the speaker.
I replaced the usb port from an other n4 and sound quality is back to normal.
i got a ls980 this month. it's beautiful and powerful. i do really like it.
but the GPS is too bad.
hard to search GPS signal and can not navigate.
i have tried to replace the GPS.conf file shared from other guys. but still,the GPS works not very good.
so i tried to fix it by modify the GPS antenna. like this:
step 1:
tape the 2 metal contacts. shield it.

}
step 2:
find a copper wire,tie this metal contact；
close your back over；
tape the other end of the wire along the phone, just like the yellow line in my picture：
step3：
launch GPS test.APK, is it works?
this is my ls980's GPS signal after my DIY:
sorry for my poor English.
hope that it can help you guys.

Thanks, works like a charm. I wan't able to get a lock even outside, but "replacement" antenna works like a charm. I even get a lock on the floor inside the house.
Might try it as i still have issues
