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 All, I have P900 which I bought about 5 months now, and all the sudden the WiFi is not working as it keep switching on and off automatically (problem which similar to S4 WiFi) and off all the time. I have been doing factory reset, and flashing roms. None of them works. Now I would like to try flashing the modem module just like S4 fix, but I have no idea on where to find those files. I would really appreciate if someone could give me some lead on this, or any other ways for those who have similar problems. Please help.
Same problem (SM-P905V)
I see that this thread is really old but I am having the same problem and I can not find anything on the internet to fix this problem. I bought a refurbished note pro from amazon last September (so it is out of warranty). This is my last ditch effort to try and fix this on my own. If I can't get any help then I will just have to send it to Samsung to try and repair it.
My wifi worked just fine for all this time then about a month ago I was having problems with the bluetooth not connecting. I ignored it at the time as I was going to work on it at a later date. Then about a day or two later it started working again.
Now about a week and a half ago my wifi and bluetooth stopped working. I have factory reset but still nothing. I can get the wifi to even turn on any more. Occasionally I can get the bluetooth to work for a minute or so but 99% of the time neither one works.
I hope that someone can help me with this and I can get it resolved without having to spend a fortune.
PS If no fix then what do you suggest as a replacement? I love all the features of the note pro. I like the stylist, the screen resolution, and the multi-window features. I need a big screen for my business. I use it for a slide show at events.

Bluetooth and Wifi have many components on mainboard, repair them is beyond anyone including professionals.
My suggestion is looking for a Note Pro with broken display or woking mainboard only on Ebay; it may cost around $120, more or less depending on luck.
Take out the mainboard is quite easy, only 3 screws at two speakers, I can swap the mainboard within 10 minutes.
http://www.ebay.com/itm/401145234611?_trksid=p2060353.m1438.l2649&ssPageName=STRK:MEBIDX:IT
Any SM-P900 ( wifi ) or LTE ( 905, 907 ) mainboard will fit to your existing tablet except rear camera ( LTE rear camera won't work with Wifi model mainboard ).
Since the thread is four years old, this is not really a follow up, but just a note in case anyone is having similar issues. Actually bluetooth + wifi repair on samsung tablets are possible for end user - if you are semi-lucky and broken components are not hard to replace items such as ICs. But first, be sure to rule out any OS level issue by flashing stock rom on the tablet. Then if the issue persist, then if you can locate service manual for the tablet in question, it comes with level 3 step by step instruction (and board view of components) on how to troubleshoot bluetooth + wifi hardware issues. Often the broken component is not the major IC itself, but discrete components such as capacitor, filter or resistor. In some cases issue may be fixed just by reflowing the IC itself with hot air rework station. So there is indeed good chance you can fix hardware issue with a bit of work and some cheap hot air rework station (such as 858D sold on ebay for $30 including shipping).
Ok the worst scenario is that wifi ic is bad and need to be replaced. Good news is that Samsung uses popular wifi ic, such as broadcom chip. And although it's a bga chip, it's quite small, making replacement using hot air gun possible. So will a lilttle bit of skill and luck, it's definitely possible to repair samsung phones/tablets with broken wifi hardware.

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 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
i have lg g2 D802 model. It had a wifi problem as u shown in your videos,my phone also behaves same like yours but sometimes it works normally like while charging,works like 2 or 3 times a day(for 5-10 min).please tell me whether my phone got ic problem or software issue

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 ?

Thank you this tip and this whole thread. I have seen this video, but still the same effect. 5-10 minutes, I can rean some news and back to flashing. I'm going to buy Huawei Honor 8 soon, it was the last chance to recover my G4. I doubt I will purchase any other phone from LG.

But bluetooth working
In cm roms also wifi tethring can be onn
But u cnt turn onn wifi
I had the same issue, can't turn on Wifi after factory reset.
I turn off my device off after one hour and reboot wifi was OK but when I want to upgrade some apps iwifi turn of again and my phone reboot with no SIM card.

My LG G2 works fine
I bought a Moto G Stylus 5G 2022 ( XT2215-4 ) to fix and sell.. I replaced the display and battery and went to test everything and it would pickup WIFI but no cell signal / data. The phone detects there's a sim card but it's like it just can't read it.
So I thought it could only be 1 of 2 issues.
1: A Antenna issue or 2: The sim reader on the logic Board is faulty.
I inspected the antennas that run from the Logic Board down to the Daughter Board and they both seem to be right and the connections snug.
// Side Question: Are there any other antennas hid out somewhere other than the two Black and white coaxial antennas that's in the back of the phone //
So I figured it must be the sim reader is faulty so I ordered a parts phone with the defects listed on the parts phone as broken display glass everything else is working..
So I swapped out the Logic Board and Daughter Board with the Antennas still attached. I go to test the phone and I still have the same dang issue with it detecting the SIM but not connecting..
I think it would be almost impossible for me to get 2 phones back to back from different people with the same exact problems..
Would anyone happen to have any ideas?
Thanks In Advance

Can you confirm that the device's IMEI is intact/uncorrupted?
Since you swapped the radio, you might need to flash a compatible modem.img in order to make a proper connection, especially if the device is from a different region than where the device is being used.
Both phones IMEI's showed clean when I did the PhoneCheck report before buying them.
Both phones are US models 1 came from California and the other Florida if I remember correctly.
Both are on the TMobile US network
I've never had a phone give me such a hard time at this point I think any profit to be made on this phone is gone so I'll probably just give it away to someone truly in need.
Pending I get it working right and I absolutely refuse to let a phone beat me lol

I've never had a phone give me such a hard time at this point I think any profit to be made on this phone is gone so I'll probably just give it away to someone truly in need.
Pending I get it working right and I absolutely refuse to let a phone beat me lol

Both phones IMEI's showed clean when I did the PhoneCheck report before buying them.

I didn't ask if the IMEI were intact when you bought them, I asked if they are intact now after you've altered things.

Is the SIM activated and has the device been activated on the network?
You've changed out all the hardware and the issue still persists, this indicates that it is a software issue. Have you tried connecting it to Motorola's Rescue and Smart Assistant flashing software and letting it scan the device to find the correct firmware and then flash the firmware that it retrieves?
Well I can confirm you're 100% correct that it's a software issue..
But still very buggy. After I do a rescue with Motorola's Rescue and Smart Assistant it somewhat fixes the issue..
It will work like it should for about the first 5 minutes and then it will revert back to the original issue. It's kinda like it receives a signal to kick it offline or something..
So just to triple check I logged in to my PhoneCheck portal and pulled yet another IMEI report for the phone and everything came out clean and clear. So just to make sure PhoneCheck wasn't miss reporting I pulled a report with my IMEI Pro account and it pulled the same results as PhoneCheck did ( Free & Clear )
So then I thought it could be an update that gets installed during the setup process that is causing it to bug out like it is. So I tried it another time and this time I told it to not install updates on setup and killed the WiFi just to be sure it had no way to connect and install any updates during setup but no dise it still gives me the same buggy results..
I swear I've been buying, fixing and reselling phones and tablets now for 5yrs and have never had a device give me such an issue..
I think it's time to just wash my hands and sell this phone as a parts only phone and start putting my time and attention into a different device..
I have a OnePlus 10T that just needs a new ear speaker and I think it will make me more money than this phone after you factor in how much time I wasted trying to get this phone to work and the money spent on the 2nd parts phone to use the hardware out of it

Could the device possibly have been blacklisted before it was sold to you, either by being reported lost/stolen or due to the previous owner not paying their bill? Even with WiFi and mobile data off, it still communicates with the network on the cellular side of the radio, it could be registering on the cellular side then getting kicked off due to being blacklisted.

On the IMEI reports it shows clean under the general blacklist area.
Then under the carrier blacklist check it shows clean.
Also keep in mind that the original device has this issue of not connecting so I bought a parts phone from a different person so I could transfer all it's internals over and the issue still persist.
While it's very possible to get two phones back to back from different people to have the same issue I would think that it's very unlikely that it would happen.
I was reading on Motorola's website forums that with the 2021 model a lot of peoples phones just started doing the same thing out of the blue after the android 11 update..
However the 2022 model ships with android 12 so I'm pretty sure Motorola fixed that bug and has nothing to do with this devices issue..
Crazy is all I can say lol

This is one of those times when it is probably something obvious that neither of us would think should have anything to do with the issue or something so subtle and simple that it is being overlooked.
