g pro 2 wifi turning on/not working fix - solution - LG G Pro 2

Hello.
I wanted to post here to help out others because I too had the same problem. Background, Ive had my g pro 2 for over 1 year (bought it refurbished). Like a few other people my phone's wifi says turning on and stays like that while draining the battery. (wifi icon keeps flashing)
I tried rebooting, changing batteries, playing with wifi settings but nothing worked. I then searched online for a solution and couldnt find any... well thats because it's NOT a software problem. Its actually a hardware problem, specifically a loose wifi chip/connection on the mainboard. I believe some lg phones are prone to the exact same problem.
tldr - Anyway the solution I found that has worked can be found on these 3 videos all with lg phones that are similar to the g pro 2. It involves placing a piece of plastic or card (I used a business card) inside the phone to apply pressure so the wifi chip has a better connection. My phones wifi has been good for almost 24 hours no problems. You can view them on youtube by searching:
1) LG G3 fixing turn wifi/bluetooth on EN SUB (or add /watch?v=1zWpzYh2DPI after youtube address)
2) How To Fix LG G4 Won't Connect to Wifi (or add /watch?v=ScLWd5lQLj0 after youtube address)
3) How to fix LG G3 WIFI / Bluetooth hardware issue (or add /watch?v=CAiu3jzKExk after youtube address)
From the videos you can see these are different phones and different users. Only common thing is that they are lg phones.
Hope it helps.

Where is the chip on mother board

wifi spits in bluetooths eye

Hi all wondering if anyone can shed some light on this one:
i recently bought a htc kaiser (yay) and its great! but i cant get wifi and bluetooth to work simultaneously in any way shape or form - every time i connect the wifi, the bluetooth connections will die - so far ive tested it with multiple devices and its a consistent problem
i even sent the unit back for a replacement but they tested it and said it was fine (i don't believe them cause i tried every which way to get it working) either way ive got the unit back now and i still cant get both to work at the same time - ARGH!!
if i cant get the bastard to work in the next week or so im going to return the unit as its inside the 28 day period - i just wanna be able to stream music from the net over wifi and listen to it using my a2dp headset
anyone have any guru zen insight on this one they feel like sharing?
cheers
fusi
must be a kaiser or rom thing cause i do it all the time at home with the hermes (go hermes go!!!)
have the wifi running fine with AD2P via motorola Ht820s
My Kaiser does both WiFi & BT with no issues. The only thing I can suggest is tinkering with your WiFi access point settings (change the channel, encryption, etc.) -- in particular, channel changes may do the trick, as both BT & 802.11b use the 2.4 GHz band.
thanks for the replies guys i swear im going loopy with this thing - what wifi channels can you confirm it works on for you?
well ive tried every permutation. it doesnt work - supergps are talking out of their arse when they claim they got it working. im really sick and tired of bull**** companies. dont buy from supergps - they might be cheap but you get what you pay for.
Why don't you try asking supergps what they did to get it working and how they have their wifi configured? Sounds to me like it's something in your setup that's causing it if they confirm the device works.
i did
they claim they connected up a lenovo laptop and a sony phone and it 'just worked'
i tried it with the exact same make model etc of kit (and a whole host of other devices (must be about 30+ different devices now)) and it consistently fails
i cant see how they got it working - unless they were testing a different unit or they didn't understand what the fault was - even though i explained the fault in precise detail in about 5 different ways to them over the duration of the day they were testing it
i reckon they just dont wanna deal with the hassle of getting a duff device back
p.s. this is with factory defaults - no customisations or anything (though ive also tried with every permutation of configuration i could conceive) - it just doesnt work

NEC Terrain Rooting and Flashing Guide

I am starting this thread to be a place for Terrain owners to come for the latest info on how to root and flash their phones. The Terrain is one of the best "rugged" phones on the market, but it has been abandoned by it's manufacturer, leaving owners to find their own solutions to problems and upgrades. This is actually a good thing price wise as you can now buy a brand new Terrain for less then $85. The Terrain has about as of hardware specs as any other ruggedized smartphone on the market currently, but at one third or a 1/4 of the cost. This makes this phone a huge attraction to anyone who is looking for a rugged waterproof phone on a budget and is why this guide is essential for users.
The NEC Terrain still has plenty of life left and this is why we need to come together and find solutions for it. Please feel free to post you success stories in rooting and flashing your terrain to this thread for the benefit of all. Hopefully, will be able to form a complete guide from all the information that get's posted here.
Thanks.

Thanks for the post and the links. It appreas that much of the information on these links are still a work in progress. Hopefully this work will continue and we can create a How To guide from this.
For those that may be interested. You can buy the NEC Terrain Unlock on Amazon for $79.99. Here is the link.

Well, I almost bricked it few days ago. :good:
I read a thread about a patch to unlock GSM in CDMA phones and saw there a code to enter some hidden menu. I entered that menu and messed a little with band settings (wanted to get LTE to work with my operator). Next thing I know Terrain stopped receiving any GSM signal and for next hour I tried to fix it. Factory reset got me 2G signal and that's all.
It turned out that the only way to fully fix it is to re-flash firmware or radio module and as we know that can't be done.
Well, this is not about unlocking or flashing, but it is a solution to another problem I and many other have been having with the predictive text bar blocking critical function keys from being accessed. The predictive txt bar is a function of the Adaptxt keyboard app and disabling it does remove that bar, but the keyboard also loses all special character function, upper case letters and numbers. After trying more then a dozen keyboard apps to replace adaptxt, I found one that works and brings back all keyboard functions without the stupid predictive text bar. It is called TouchPal.

Forgive me for this slight OT-posting, but it's not that easy to find people with this device - let alone an unlocked one. I'm located in Germany and the device runs just fine - except for the fact that Tethering does not work - neither USB nor WIFI. The PC can connect to the phone, however the connection in Windows 7 always is shown as being limited (no internet access), while internet on the phone works fine.
GMail - as well as some other functions of google also rarely sync and basically just do so on request, while they sync just fine when being connected to Wifi. And no, background data are not restricted in the settings.
Has anyone experienced something similar?

I have the same problem! After few minutes of "thinking" phone reports "There is a temporary nework problem... bla, bla, bla"
Is there any suggestions how to fix it?

Well actually I know that message as well. For me changing the APN helped. You could also try to restart the phone. I just remember I also had this problem sometimes. But like I said - even without that particular message I would not get tethering to work.
iDomino: Do you also experience the problem with syncing that I had?
That's funny, actually I haven't noticed syncing problems untill I read your posts. I myself have all the same problems that you mention.
Even more of that, Terrain has some silly feature that TURNS OFF WI-FI if it thinks that that hotspot has no internet connection. It is massively annoying and can drain all your data traffic. The only solution that I found is to install the app "Smart Wi-Fi Toggler", it constantly turns wi-fi on if terrain turns it off, but only in places where I turned wi-fi on myself (like home and work).
It's a pity the phone has so many flaws and due to its tight security and the locked down NEC mobile devision no one can do anything about it. I wonder if this just affects the users who use an unlocked phone outside the US or if people in the US have similar problems. I have tried contacting NEC about this - actually about providing us with some kind of unlock mechanism - but all I got was this:
"Dear Sir,
Thank you for inquiry.
We, however, regret to inform you that our phone is not available about your request.
If you have any issue, would you try to contact the company or shop where you have purchased this model, who might be of help to you.
Thanks and Best Regards,
Fujii /NEC"
By the way, I discovered a new bug: When Roaming the actually used Network-Provider is not shown and I also didn't find a way to choose one...
Do you also experience the problem with syncing that I had?

I had some sync problems and I don't know working methods to fix it.
First time I solved it this way:
turning off apps sync -> open Gmail app -> it will show notification offering to enable synchronization -> use it -> sync works.
But this solution worked just once. (
Other time sync turns on by itself after one day disabled.
P.S. My Nec reboots while connecting via USB to ubuntu laptop.
Battery life
Can someone tell me how your Terrains battery hold up charge? Because mine discharges completely in about 10 hours (without using phone at all). I think it's wakelock problem.

Does it crashes once or infinite loop begins? I had infinite loop problem while connecting NEC Terrain to Ubuntu, Linux Mint, Debian or CentOS. Removing "ModemManager" package solved it.

My phone works about 25-30 hours (30 min. calls, 5-10 sms, 30 min. messaging, 2 hours e-mail, internet & other applications. No video/gaming/music at all).
Infinite loop. Removing "modemmanager" helps! Thank you! :laugh:
Also got spontaneous rebooting after installing FTP Client made by Zifero. :silly: Removing app solved the problem.

Another Terrain user here!
Hi guys!
i am Kharl
i am another Nec Terrain user here!
due my lifestyle, i needed a phone which could gives me reliability and power under ANY circunstance, that could be done by any rugged phone, BUT i needed querty keyboard, fm radio, gps, gyroscope, accelerometer, loud speakers, that could work worldwide and touchscreen... the only one with those features was the Terrain... and with the extra, that it is amazingly cool, i dont know opther but i find this phone really cute, very sober and elegant design.
well, i live outside USA so, for me, to work it couldnt be locked to ATT, so i was able to get one unlocked.
my phone has almost all the problems you mentioned, althught i am still happy with it and i am not going to change it because its problems does nto interfere a lot with me, BUT of course id like to get those problems sovled.
trying to solve the problem i bough three of thes phones and all the three had the same problems
the first one was by mistake, locked to att, but it had the same problems, random restart and locked hotspot, i sold it, i got a second one, works with any sim, everything fines, but with the same problem, random restart and no hotspot, i bought a third one to see if the problem was with my particular phone... and n luck the same problems.
it has some other minors problems, like no stereo audio recording despite it has two mics and IT STATES IT CAN record in stereo, but thats not a problem, i can deal with that, and sometimes the people at the other side (while in a call) says my voice sounds like from within a box (lack of trebble or too much bass) and when i press the check too much to the phone boddy there is also clarity sound problem.... but thats ok....
regarding the two main problems
random reboot and hotspot
many of us suspect what the cause is
for the random reboot many could think it is a installe app which is causing it... NO, because it does it at factory state, to solve that i dotn think root is needed, there is a certain factory process that is causin to reboot, the reboot is VERY random, could doit threee times in a day or could happen only three times in a week, what i have notice is that it happe lessoften in cold weather.
the hotspot problem IT IS cause because att locked that function, even when the phone is ulocked, that part remain locked because ATT.
what about you guys?
u can try hard reset for begging

[Q] Bluetooth very short range ( less than 1 cm) - issue

Hi All,
I have a Note pro 12.2 Wifi edition (SM-P900) with a bluetooth range of effectively 0. To get it to detect any other BT device i have to put the other device on top of the front facing camera or on the edge of the device close to there. If I move it a couple of centimeters(< 1 inch) the note pro disconnects. when for example the keyboard is touching the upper edge of the note pro and they are paired they work as expected but if I move it a couple of centimeters they disconnect . I tried this with a microsoft bt keyboard, an samsung s3 mini and a note 8.0 and it's the same issue. All the other devices work with each other as expected so it's definitely the note pro.
Things I've tried:
- complete wipe/factory reset
- 2 different oem firmwares flashed through Odin (now on the KOT49H.P900XXUANI1 build) + factory resets
- the latest cm11 release from the forum here
- set the BT visibility timeout to never
- tried with wifi off (just in case)
- tried with and without cover
I have some questions:
- Anyone faced something similar on this device?
- is there a fix or a suggestion I can try?
- is there a debug menu or tool for the Bluetooth to see numeric signal strength in dbm, kernel logs, etc.
- where can I find the pit file for this device? I didn't try complete repartitioning because I couldn't find the pit file.
- is there a disassembly guid for this device? I am tending to think it's either a disconnected (or broken soldering) BT antenna issue or a firmware bug and I prefere to check the disconnected antenna issue myself if it's doable rather than send it to Samsung for a couple of weeks of wait time.
- anything else I should think of ?
Thanks

Hi!
To me this sounds like a hardware issue. A disconnected or improperly connected antenna is a very good bet.
Is this an issue that came along together with an update, or perhaps app installation?
If it´s an issue right from you recieved the tablet i´d send it back if it´s still under warranty.
I have previously removed the back of my -905. It´s not that difficult.
You´ll need a sturdy plastic separation tool of some kind. The back is very thightly attached with closely placed plastic clips so a fairly high amount of force is needed to begin with. A guitar pick won´t cut the mustard.
I found it easiest to lay the tablet down front facing downwards on something flat that lifts the tablet about an inch off the table. This gives your hand room for the "right angle of attack" I started at the top right next to the IR-diode.

Elo, Thanks.
I bought it as an immaculate second hand from ebay (it didn't have a tripped knox at the time) and had it for a month before getting a BT keyboard to use it with by which time I've already had routed it and tried different firmwares. So can't tell if it's a software update that messed it up.
In fact, I wasted a couple of days going through different firmwares before discovering the range issue by chance. At first I just thought it's an incompatibility between the keyboard and the tablet.
I will try to take it apart; I'm hoping to get the "prying" kit tomorrow. Thanks for posting the pics, I was going to try from the front but from your pictures I see I have to remove the back cover.
Cheers,
Fadi

Epic GPS not working problem, on MT65xx devices after flashing, can it get a fix?

So you already tried everything that's available on the web to fix your Chinese phone GPS after a stock/custom ROM Flashing, and problably your device is a MT6572, MT6577, MT6582, MT6589(T), MT6592, MT6753 or any other media tek.
You already tried:​
1 - The classic method, that shouldn't even be mentioned in a case like this, and felt like an idiot:
* DOWNLOAD EPO AND ENABLE AGPS.
2 - The Plan B Method: Used Faster GPS app to create or manually changed your GPS.config file.
3 - The plan C Method: Deleted mtkgps file and restarted.
4 - The plan D Method: Searched for a NVRAM file on the Web and tried to restore it using MTK Tools.
5 - The plan E Method: You downloaded/replaced the file libmnlp_mt6572 in your system/xbin folder.
6 - The plan F Method: You Downloaded/replaced the files mtk_agpsd from bin folder, agps_profiles_conf.xml from etc folder, android.hardware.location.gps.xml from etc/permissions folder, gps.default.so from lib/hw folder and mtk_stp_gps.ko from lib/modules folder.
7 - The plan G Method: Perhaps you tried some African ritual...
8 - You climbed Mount Fuji to get some signal, and had to keep your screen ON in the GPS APP during 2 hours.
9 - You tried some Native Indian ritual...
10 - You hacked you GPS Antenna, building a custom one as it is shown YouTube tutorials, and it works... for the guys who made the videos.
Your GPS was working before flashing, even if weak, so you know your hardware is not broken or something.
11 - You tried to transform into Mumm Ra the ever living!
12 - Like me, it's been over 1 week since you decided to fix this issue, and you're about to pull all your hair. In my case I'm spending hours on this, I'm really trying to get a solution.
AND NOTHING WORKED AFTER DELETING, REPLACING, DOWNLOADING.
You even learnt and tried using EXPELLIARMUS!!!
Still didn't work...​
And your GPS still can't get a lock, even with all the network aid, all the tutorials you found in the web. If you religious, you even asked Jesus to help you (At least that was my case). But your phone is still the same.
Now you feel like an idiot that is never, ever again going to buy another Chinese phone anymore in your life, but you don't want to discard your phone, what you're going to do?
Well I -- STILL -- haven't found a solution, but I found a clue that may lead to a solution. Since I'm not a smart ass programmer that knows basically everything about Androids, I humbly come here now to open this discussion and see if we can finally find a solution for this problem that I believe it already annoyed at least 1 hundred people around the globe.
My clue is:
1 - I saw some people saying that when they restored their NVRAM backup after flashing the stock ROM, they got their GPS working again. So it is related to NVRAM, but with what in NVRAM?
2 - Today I was testing some hacks, when I disabled my SIM card, I the GPS TEST app could not find any satellites anymore, and I was using wifi, so it makes no sense at all, I mean, could the GPS be using the 3G/GMS/WCDMA band?
I believe the GPS device is operating in a different frequency, probably the same as the SIM CARD, and that's why people can't get a lock.
That's related to NVRAM. Perhaps with the 900/2100 and 850/2100 operator frequencies.
Let's discuss and see if we can find a definitive solution for this case, please.
Found this in another forum:
we were discussing this point also in the thread regarding unlocking the 3G bands.
it seems that neither the NVRAM nor the ROM alone has much effect regarding to the GPS, but it seems that if either one does not match the other you can also have trouble with your GPS.
how it's connected i do not know - actually as you said it should not be connected at all.
but it's pretty much clear now that the 850/2100 and 900/2100 phone have at minimum different radio hardware.
We were not able to determine how the bands were locked/opened through the firmware (since it would make sense that in theory both are available but can be turned on or off by the manufacturer, because its more expensive for MTK to produce actually different radio hardware) so that suggest that there is a hw difference. that could be connected to the GPS also.
in other threads people had reported that by upgrading the firmware they nuked their NVRAM (lost IMEIs, changing MAC address etc.) and most of them had problems with the GPS afterwards.
better safe than sorry. if you really want to try this out, please make sure to have a working backup of your NVRAM beforehand.

Wi-Fi not working anymore

Hello everyone,
the wi-fi in my Nexus 5 does not work, happened suddenly, usually does not activate and when it is activated not find available networks.
I found this thread in this forum:
http://forum.xda-developers.com/general/help/qa-wifi-stuck-mac-020000000000-g2-g3-g4-t3452133
in the second message of this discussion there is a user message explaining how to solve the problem, some users managed to solve by following this information
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!
