Hi everyone pretty new to the Chinese phones and apologies if this has been done before (i cant find it) but i have a JIAYU G4 youth which is running the latest custom rom off needrom.com (JY-G4 Yabe V7.0.2) this is the 3rd rom i have flashed and each one the GPS is very slow or does not work at all and you can not get a fix. The only way i can get it to pick up satalites is to use the engineer mode on mobille uncle tools which is quite long winded.
Ok so to my question "can the gps be improved by some sort of configuration?" I notice in the root of the sd card is a gps config file does this need altering somehow when used in UK?. Any help would be much appreciated as other than this it is a great phone.
The problem is rather the antenna in the back of the device when the device screen up and metallic body, the blocked antenna. GPS works well when the device display down.
But there are some guides on how to improve GPS software (according to me do not work):

This is more than only a hardware (antenna) problem. I've noticed that when I connect an external BT mouse that the mouse itselfs gets a "spot on" fix, but the phone is struggling to keep this fix.
By editing the build.prop and disable JIT the phone has a much better GPS fix.
GPS fix issue in Jiayu G4
Finally the issue is solved by 100%
The problem is rather the antenna in the back of the device .
The PCB has contacts for GPS antenna , the 1st & 3rd are the ground & the middle i.e 2nd is the main antenna.
I just skipped 1 & 3 contact by putting insulating tape between contact & the antenna.
Only 2nd point is touching the antenna .
just that's all.
Now my phone fixes GPS with in a minute in cold start.
I tried with most of the available ROM.
Pls note : If you are not a technical person do not open.
refer to some mobile repair person .
soon release the photos of the same.

Hi Pankaj459,
I tried the software fixes, which got me a quicker fix. Unfortunately the fix is not very accurate.
Very often the GPS loses its way and I find myself about 100yards beside the road or in a nearby street.
I opened up my G4A and noticed that the 3rd pole had already been isolated with black tape. I did also isolate the left pole. Nevertheless, did not see any difference.
The fix took just as long/ short. Accuracy was just as dismal.
Is there anything else I can do? Would it actually help if I modded some copper wire to the GPS contacts, or would that not solve the issue?
Thanks in advance for your help.

So do you think the solution has to do with putting aluminium paper in the antenna? I have seen that fix in THL and it seems to fix the accuracy, maybe it is the solution.
Would anybody share a little tutorial on how to do it?

Hi
You should try to follow this step by step tutorial about configuring GPS + antenna mod , it reaches up to two meters accuracy in motion in a Jiayu G4T :victory: :victory:
A version in Spanish is available as well --> Versión en español :highfive:
I got a Nexus 5 off a friend for a decent price because he dropped it and bent it up a bit. After giving it a quick look, the only thing that seemed damaged was the black little coax wire that connects the main board to the board on the bottom (Assuming it goes to the antenna), The end simply got bent off. This was an easy fix, replace the cable no worries. The real problem is when I went to go test the phone after I fixed the cable, it doesn't get any cellular signal (Wifi/BT still works), draws a crazy amount of power and the 'Qualcomm WTR1605L' chip specifically gets extremely hot, to the point of overheating in like 30 mins. Rather than tossing a bunch of money into replacement components (or getting another nexus 5 with a bad screen or something) I'd prefer to narrow down the problem to one specific component. This leads to my question:
Does anybody have any ideas to how I can further troubleshoot and diagnose this problem, or knows what the problem exactly is?
I have tried a few things, like if I flash the LG G2 radio (A trick I learned I could do with my Nexus 4/LGOG, after backing up my EFS just in case), Wifi and Bluetooth still work while Cellular, GPS and most of the other sensors do not. This stops the big power draw and overheating issue, but doesn't really do anything to further identify the problem component. I noticed that the modem image could be mounted as vfat and you can mess around with the various parts of the image. I don't know which files do what, so I have thus far left it alone.
I know this seems like an odd question to ask here, half the time I see responses like "Send it into Google/LG and have them fix it for you" but that isn't really applicable in my situation
Also, I know that my SIM is good, it works in my Nexus 4, I know that my ROM isn't a issue, because I have multirom installed and tried many different roms. The Radio image shouldn't be an issue because I had updated the phone from 4.4 to 4.4.4/L Preview since I got it (Using the google images and flashall script). IMEI/Whatever the ESN equivalent shouldn't be bad, my friend had been using it before he dropped it.
Thanks in advanced for any ideas, and sorry for the long and comprehensive almost to a fault thread.

Dropping a phone can sometimes cause invisible damage (like BGA solder joints failing). Visual inspection can only tell you so much.

I used to build small electronic projects when I was a kid. When something overheated like that, 90% of the time it was a short or a the wrong value of component. It's possible the drop caused the antenna connector to short out. Try disconnecting the antenna cable and try again with the stock radio firmware and see if the radio continues to overheat.
(I'm not sure how flashing the radio would prevent overheating, unless the original firmware simply turned up the transmit power in an effort to contact the tower, but that's my first guess and should an easy thing to eliminate).

Thanks for replying! When I get home I will give it a shot and see if it still overheats, then update this with my findings.
If it is overheating then it must hardware issue. Worst case is that the PBC board has a crack somewhere because of the bent. Grab the service manual from the general forum and start mesuring the components to find out where is the problem.

It seems to overheat with our without the antenna cables on the stock radio. I noticed that it still gets warmer than it should with the G2 radio, it just takes a lot longer.
That service manual is really comprehensive but unfortunately, it is going to take me some time to actually get to looking it over closely.
Hey guys,
was in to the tmobile shop when i got water damage. They tried to hook it up to a diagnostic tool but it didnt connect. I have my suspicions that this is some sort of tool that uses ADB communication to diagnose issues with the phone. Since i have been in there my usb connection has come back to life. Anyone ever heard of a tool that would let me diagnose hardware issues? I have a feeling that the issue with my device is simply the antenna or the sim reader. Everything else on my device works fine. Wifi, gps, camera, speakers, microphone, everything. Touch screen all of it. Even the vibration motor works great. Just dont get any reception on the device. any thoughts are appreciated! Thanks guys!
Water damage can be fatal. Even tho every thing else may be fine... Sounds like the radio is fried.
If you can manage to flash stock and it's the same, it's fried.
If you can't get it to communicate with the pc.. Again... May be the water damage.

It can communicate with the PC-------> i plugged it in this morning to charge and the file explorer sprang to life. I can access everything on the device now.
right now the signal goes from "no service" to "emergency calls only" intermittently
You already have a thread here: http://forum.xda-developers.com/google-nexus-5/help/water-damage-t2830408
This is a question directly related to the water damage so I suggest you ask this question there too.

[Q&A] WiFi stuck on turning on; MAC 02:00:00:00:00:00; G2 G3 G4 G5 Nexus5 Nexus 7 etc
Hi!
If you are reading this now, you are probably one of the unlucky fellows who's WiFi (and Bluetooth) stopped functioning, and if so, you are probably deperately searching for a solution/fix. I might have something for you, but first:
*** DISCLAIMER/WARNING ***
You yourself are exclusively responsible for whatever may (or may not) happen to your mobile device, to yourself or others. I am only giving hints/advices here that *MAY* help, but I will not take any responsability, nor will I provide any support, in absolutely *ANY CASE*, including, but not limited to: your problem not being solved or/and your mobile device becoming partially or completely broken. Let me be very clear: If you do anything to your device rendering it useless, destroying it, seriously or fataly injuring you or others, and then come blaming me or/and cry for help, I will point my index finger at you and laugh at you. Period.
If you are a impatient person and want to get straight to the point, jump right to section 6.

0. Foreword
Two or three months ago, one fine morning, the WiFi/BT of my LG G2 suddenly stopped working. Initially I thought this would be only one stupid annoying minor thingy, that I’d be able to solve it fast. I was wrong.
1. Description of the problem
When turning on the WiFi, it would just stay in "Turning on..." forever. Similar thing for Bluetooth: It would stay on for a few seconds and then turn itself off again after. (But then, who needs Bluetooth anyway, WiFi ist probably 100 times more important...). I have thoroughly searched the internet, and I found quite some videos with exactly the same problem (remove the two blanks from the links to watch):

h ttps://w ww.youtube.com/watch?v=4W8YJMDFM88
h ttp://w ww.dailymotion.com/video/x2cuyjt_nexus-5-turning-wifi-on-frozen-problem_tech
2. Urgent advice
I want to prevent you from wasting countless hours searching for a solution - I wasted so much of my time already, no need for you to repeat that. Therefore: *Please* be aware that there is a VERY HIGH PROBABILITY that this issue is being caused by a hardware defect. I can not speak for all devices of course, but keep in mind that the main reason I wasted so much time, was me beliving it was some software issue! See the next section for a glimpse of stuff I have tried without any success:
3. Things that *DIDN'T* work
01. Restarting WiFi/Bluetooth several times
02. Rebooting the phone
03. Turning airplane mode on/off several times
04. Slapping/hitting the phone (this was indeed suggested in a forum)
05. Using WiFi-Fixer apps
06. Resetting to factory settings
07. Upgrading to newest Android version
08. Fully drained the battery and left it uncharged for several hours
(Rooted the phone)
09. Deleting the /data/misc/wifi/wpa_supplicant.conf
10. Deleting the whole /data/misc/wifi folder
11. Creating a file named ".bdaddr" in /persist/bluetooth containing a MAC-Address in hexadecimal format
12. Creating a file named ".macaddr" in /persist/wifi containing a MAC-Address in hexadecimal format
13. Flashing several custom ROMs to it (CyanogenMod, ParanoidAndroid, ...)
14. Going back to stock ROM
15. etc. etc. etc.
16. Several combinations and permutations of the above
4. There is little hope
Again, as the cause of the problem is most likely a hardware issue, I don't recommend going through all the steps as described in the previous section; however, though none of the steps worked for me, this doesn't mean that none won't work for you neither; you might be luckier than I was. In that case, enjoy your restored WiFi and be happy.
5. My most obvious advice
You need to replace the motherboard (main board) of your device.
Honestly, if you can afford it and it doesn't cause too many inconveniences to you, you'll be better off by simply buying a new device. If you don't want to buy a new device, send it in for repairs. If you don't want to do that as well, you'll have to fallback to a DIY solution:
I. Buy a new main board for your device. Be careful to get exactly the right component for your specific model. If you dont find any shop selling those, there are plenty of individuals out there that own devices with broken displays. You dont need the displays, you need the motherboard. Buy one such broken device, and you'll have your main board replacement.
II. Replace your main board or let someone else do it for you
Continues below.
continuation
6. LET'S GET SERIOUS!
If you are reading this, you either didn't read or you decided not to follow my most obvious advice in section 5. So be it. If you want to carry on from here, be sure to re-read my disclaimer at the top of my post.
There are 3 DIY possible fixes for the WiFi problem - none is guaranteed. I will describe them from the most harmless to the most kamikaze/deadliest. All of them will require you to open your device; if you are not careful and damage any of the components inside, you will end up with a worse device than before - but hey, don't say I didn't warn you.
At this point we assume that the cause of the problem is a faulty solder joint of your WiFi IC. The goal is to try to restore that solder joint. To do that, you will have to:
I. Open your device
II. Find your main board and separate it from all connected plugs
III. Find / identify the WiFi IC chip on the main board. I recommend searching for a service manual for your device, or/and searching for a disassembly video for your device; you need to know which one of the chips on the main board is the WiFi one.
Once you have identified your WiFi chip, you have 3 options, which you may combine with each other, but I recommend to try them out one-by-one as follows:
6.a Sellotape / Scotch tape
You need to make sure that your WiFi chip is pressed against the main board (ideally, this ensures the broken contacts touch each other, solving the problem). The best way to achieve this, is to attach a series of tape strips on the top of the WiFi chip, causing it to be pressed against the main board by the surrounding cover/hull once you reassemble/close the device. The tape strips are just a suggestion, do whatever you find convenient as long as you ensure that the chip is pushed against the board at all times.
This method may solve the WiFi problem already. When you turn your device back on, give it some time (5-10 minutes) and reboot it a few times if the problem still persists. My own WiFi didn't function right away, but after a while it finally recovered - hurray!
6.b Refrigerator / Freezer
Instead of using the tape as described in 6.a, you may first try to put your motherboard in a fridge for a few hours/days. But make sure to put it there in a plastic bag, and avoid moisture as much as you can, specially when taking it out of the fridge. Make sure its completely dry before reassembling your device!
By the way, try the refrigerator option BEFORE you try the freezer option!
6.c Oven
If everything else fails, the oven might be your last chance. This is not a joke, but as you probably can assume, it is "All-In" i.e. highly risky. The theory behind this is that high temperature will cause defective solder joints to reflow, reconnecting and thus fixing the problem.
You should only try this as a matter of last ressort. Be warned that you may fully destroy your main board, and there is a high chance that you will. Also, you may cause serious injury to yourself or others. Make sure you make backups of your data first. DO NOT BAKE THE WHOLE DEVICE, ONLY THE MAIN BOARD. DO NOT BAKE THE BATTERY!!
If you are still reading:
I. pre-heat your oven to 385° Fahrenheit (196° Celsius)
II. put your main board in the oven, bake it there for 7 minutes
III. remove from the oven, let it cool down until every component of the board has room temperature
Finally, here is a video of a guy doing a similar thing, but with a heat gun:

Ok, this is all, I hope I could help you.
Good luck!
Summary
Hello all,
first of all, I want to thank brysclar and xbing6 for their valuable feedback! Thanks a lot guys! :good:
Now, in an effort to update this thread and in an effort of trying to summarize it in fewer words (my disclaimer above applies!):
- The described problem seems to affect mainly (all kinds of) LG devices
- The issue seems to be caused by a defective soldering of the Wi-Fi chip on the main board
- The defect seems to be induced by dropping or/and overheating the device; recharging the battery, big/long app or android updates or the flashing of custom roms could cause excessive heating
- brysclar pointed out that replacing the battery might solve the problem (I haven't tried this out myself, so I can neither deny nor confirm this)
- My recommended solution is 6.a - applying pressure on the Wi-Fi chip, pushing it against the main board, using tape stripes
- There is a video of a brasilean guy doing some similar, but using pieces of an old credit card instead of tape strips: https://www.youtube.com/watch?v=OJkdva2iOag BUT PLEASE NOTE THAT HE IS APPLYING THE PRESSURE ON A RANDOM SPOT, NOT DIRECTLY TO THE WIFI CHIP! It *may* work for you, but if it doesn't, find/identify your Wi-Fi chip and apply the pressure there
- If everything else fails, and only as a matter of last ressort, you may try what I have written in 6.c
So... this thread has over 500 views, but not one single reply.
Guys... what has your experience been? Have you tried anything out from the posts above, and if so, what was the result? Did it help you? Do you recommend anything? Has something else, not written here, worked for you?
There are a lot of people out there having the same problem. It would be great if you could give any feedback, share anything that helps the community.

I honestly didn't see this post before. You really covered every detail very well. So far, returning my G3 to stock and replacing the battery has fixed it for me. Weird. I know. I did try 90% of the things on your "things that don't work" list and you are correct. They don't work.
wlanmac 02/00/00/00/00, Bluetooth is OK
Hey, i just got an LG LS990 with same Wifi issue and i'm ready to try so WITNESS ME!
Thanks for an amazing and detailed post lml
Simply awesome.
I have similar issue with my Nexus 5x. It is QCA6174 hw 3.2 chip, lspci does not detect this chip any more. I am going to do a little bit investigation from device driver (cnss) perspective. It enables one GPIO to provide power to this WiFi chip, I will try read back this GPIO status to see if it is enabled. I do not have the schematics, I do not know how to check if power is supplied to this wifi chip.
lspci used to show below:
$ ./lspci
00:00.0 PCI bridge: Airgo Networks Inc Device 0300 (rev ff)
01:00.0 Network controller: Atheros Communications Inc. Device 003e (rev ff) (this is qca6174)
If kernel driver investigation does not reveal anything helpful, I will ask other guys to replace the chip.
I thought it is because of vendor partition is accidentally wiped out, maybe it is unlikely.
---------- Post added at 08:49 PM ---------- Previous post was at 08:40 PM ----------
As Bluetooth can not be turned either, I am tending to think this is hardware related as well. As described previously, I will see if I can check that gpio status.

Hi xbing, and thank you for your feedback! :good:
I am really curious and looking forward to hear the results of your investigation! I believe that in your case, too, the Wi-Fi/BT chip is not being supplied correctly due to a defective soldering. Note that I don't think that the chip itself is defective, only the contacts between the chip and the main board. So, before replacing the chip, I'd recommend to first try what I've written in 6.a (or check my update/summary above).
Keep us posted about everything you find out!
Sprint declined to fix my LS990 due to "water damage" being the reason for it not working, and wanted to charge me a $150 deductible for a $100 phone. Shimming the WiFi chip against the metal covering with some thermal pad I had lying around and adding a bit of sticky foam on top of the ribbon cable for the camera worked great! Much thanks!

Hi NavHur,
since the problem is mostly caused by a loose Wi-Fi chip, respectively a defective solder joint, using thermal paste or grease is unlikely to help; again, what you need to do is to have your Wi-Fi chip pushed against your main board. You can use your imagination on how to accomplish this; what Tomcat5 described he did ultimately led to exactly having his chip being pressed against the board.
Of course you are free to try whatever you want - if you find new solutions please post some feedback.
Good luck.

Thanks you so much, I placed a small piece of plastic above the wifi chip and one next to the camera lens. Now the wifi works fine. However my screen was pushed up so it bended a little. The faulty thing was my battery, not the added plastic. I compared mine with the one of a friend, mine was 1 mm bigger. (also with the battery of my friend's g3 the screen was fine)
I'll be changing it soon.
same problem as u but sometimes wifi works(mainly fully charged) and sometimes dont

Hi Pratap94,
nobody, neither here in this forum nor elsewhere in the internet, will be able to give you a reliable answer without having a *physical* look at your phone. Nobody.
However, I can give you my opinion, based on the stuff you wrote: The fact that it works normally sometimes, specially while charging (probably it heats up in the process?), indeed seems to indicate a hardware issue. I believe you have a loose Wi-Fi chip i.e. a defective solder joint, like I had on my LG G2 D802 as well. I solved my problem by doing the stuff I described in 6.a.
Good luck.
Thank you so much

Hi Olzhas18,
that might be an indication that your WiFi chip is still a bit loose and is not sitting tight enough on the main board. On LG G2, it is difficult to push the chip against the board because it's covered by a metal cover...
Also, did you check out this video: https://www.youtube.com/watch?v=OJkdva2iOag ?

I have a problem with my Nexus 5 in that it overheats to around 70 degrees (got to 101 at one point!) Just by being on, even without using it. It even heats up when you check the battery when powered off (by pressing the power button once) only by a little bit.
I also have another problem, the phone can detect the SIM card and displays the number on the SIM, but it says no signal.
A third problem is that when the phone is locked and the screen is off, it randomly restarts. This doesn't happen when the phone is in use.
I would really appreciate if you guys could help me,
Thanks
1. What rom are you using? do you use a custom kernel?
2. try reflashing factory images.
3. remove simcard and enable aieplane mode. check if it reboots or lverhears
the round antena wires come loose afaik. i ordered a new set lf antenas and replaced them. phone is much cooler and i get better reception and battery life
I'm running the stock android 6.0.1 which I flashed.
It detects the SIM but doesn't get a signal,
I checked and the wires are not loose, maybe I will order the antenna wires as a last resort.
If anyone has any other suggestions, feel free to tell me

Is your GPS working? My Nexus5 have same issue as yours plus GPS is Dead too. After some search I found that the GSM chip is the same of GPS so I think the problem is the chip itself.
