[Completed] Multiple batteries at once - XDA Assist

Dear XDA,
I have an s4 clone, and after a little messing about here and there, trying to install a custom recovery, a couple of stuff and i ended up with a recovery i cant access (looks like there is no recovery at all) and seems like i wiped my imei. The phone is cracked and the gyro doesn't work, so this is an experiment phone. I was thinking of wiring a few of my old phone batteries into that and taping/gluing them to the back. It might look hideous but it is an experiment. I have wired a bigger battery to another phone, positive to positive, negative to negative, and the central data wire to data. Worked flawlessly without any calibration or anything of that sort.
My question is, if i wire everything together, will all batteries charge? Do i need to edit some files to make it work perfectly? two of the batteries are 2500mAh and the main phone battery is 2100mAh. they don't have to work to the full extent, but at least give the phone some power. I use the phone as an ip webcam and monitor my WiFi with it so it just sits at home. What would be the best option to do without any kernel tweaks? I do not mind charging times, I do not mind the looks and shape, I just need it to boost my battery performance. Any help, ideas, links, etc. would be very handy
Thank you.

Hi,
Thanks for using XDA Assist.
You play a dangerous game IMHO but try posting your question in this general Q&A thread: http://forum.xda-developers.com/showthread.php?t=2257421

[Q] Little Problem with modding my Samsung Mesmerism!

First I would like to introduce myself to these fine forums.
I am I_like_noob but commonly go by the handle "notch" on other parts of the web- most notably the minecraft forums.
I have been active in the phone modding for 50 years. I still remember getting my first rzr as a youngster. You seem to have a great community here and I hope to become a part of it.
I am attempting to do a battery mod on Mesmerize where I modify the connections in my battery bay for mesmerize. When the connections are done being modded I will estimate that I will be able to fit 25 watch batteries into my phone. Not only would this allow for easy hot swaps for when I'm on the road (I am a credit default swap salesman) but it would also increase the battery life of my phone to as much as 25 years! I figure that if a battery watch can power a watch for 25 years then 25 batteries can power my phone for 25! please tell me if there is anything wrong with this.
Now to my problem- I am unable to remove the battery cover on my mezmerize. I have melting it off but the only thing that accomplished was making my phone not turn on anymore. In order to alleviate the heat problem I currently have the phone in a bucket of ice water. Please tell me how else I can fix the phone.
Guys please help me with this. I only got this phone yesterday and I really wan't to mod it.
Thank you so much for your time.

HTC for life?, One X has sent me packing.

I've always had an HTC phone everything from the EVO shift (yee yeah), to the Inspire HD, then got a Vivid, now I'm using this One X AT&T. I've been spoiled by Sense, I can't imagine having to use a Samsung. It's nice, fast yada yada but geeez its bubbly icons kill it for me.
This OneX I can't understand why the All the softkeys or home keys have been changed. The back key is for left hand people, Why does the recent apps button even exist and then put it in the most convenient place? No battery? What I mean to say is no extra battery. Ive always bought an extra battery so that if I don't have a plug-in or charger I got it covered.
Can someone give me any reason why the charge port is on the side?
No SD storage... This is probably the main reason Im done with HTC. A factory reset from the bootloader erases everything on your phone including backups. EVERYTHING ON YOUR PHONE! Not the recovery though...
Is there any way of securing the data so this never happens?
Now my camera has went out. No camera.. Ive tried everything, I even called HTC support they tried and they say "need new hardware". I really hate to tear into this phone.
I never write these vent posts.. I would fight someone lastweek if they talked trash about HTC phones. Maybe I got lemon, it's just One thing after another.
Although it seems like I'm trashing this phone I really love it. I just can't store anything important on it or take pictures, video.. I've read so many posts on replacing the camera but I just hate to tear into it. Any suggestions would be appreciated. I never knew how important it was..
No one can say anything bad about the screen on the One X. It's amazing..
Sound is great
Smooth running phone too..
I'm scared to spend money on another HTC product. Maybe there is a way to try out a phone for a couple days that would be great.

You have the right to voice your opinion but this isn't really the place to do it. You're just knocking the phone. It's not a perfect phone, but it's really good once you get it rooted and all that. Stay respectful, everyone!

I'm wondering why you bought it on the first place.
Almost all of your complaints are hardware ones that you know about before buying the phone?
Personally I don't mind the hardware at all. External SD would be nice but not a big deal. And I like right side unlock buttons.
As far as the camera I think it was just bad luck or damage. Haven't heard about it happening much at all.

My niggles:
They put pogo contacts on the phone... but couldn't be bothered to make anything that actually uses them.
9.xGB of storage when I was expecting the typical 14.xGB for a phone advertised with 16GB.
HUGE pain to get root early on, though partially att's fault.
The phone loses signal if I leave it face up. (really gotta find time to get that fixed...)
Other than that, it's been an awesome phone.
I think HTC could've improved more in the music department and camera, but I agree with RollTribe. It's not a perfect phone, and there will never be a perfect phone imo. For me it was the software and hardware (GPS works!!) that made me stay.
Overall I would consider the XL solid. I'm going to look past the HTC One, though, and wait for the next generation.

I think the back button is in a perfect spot for right handed people, it is right in reach of my thumb when held in my right hand.
You complain about the recent app button, but I don't follow your complaint. It exists so you can multitask, you say it is in a convenient spot and I agree, easily accessed by the right thumb when held right handed.
Extra battery? I have never found myself wanting to buy extra batteries for any phone ever. I just charge mine when required. This phone lasts a full day easy if you are not playing games on it. I am a heavy phone user with maybe 30-50 calls every work day, sync an ics calendar every hour, use calendar, contacts, browser and email a whole bunch. The phone lasts the entire day. These days with my car dock I can play games all day without issue
Charge port on the side makes for easy landscape car docking, perfect for GPS. I slip mine into the car charger often these days, it is one of the easiest phones to get in and out of the dock as the charge port is on the side.
SD storage, again I use my phone for a whole bunch of things and have never gone close to using the full storage. I stream over Spotify via Bluetooth to my car head unit. I have about 20-30 user apps installed. I just can not fill the phone. I even have the 16GB model from Hong Kong while most around me who bought from Telstra have 32GB.
I have had my phone for 15 months now and the camera still works perfectly. My last phone(s) was a Nexus One and a Nokia E68(or something) I smashed the camera lens on the Nokia before 12 months, not sure how, but my One XL is fine.
Then the next user, Zodiac:
I like the unlock at the top, easy to reach with right index finger, but can not be accidentally pushed.
Then, antichamp:
pogo pin issues( I initially really wanted to use the pogo pins aswell just for the gimmick until I realized they only seem cool)
1)The pogo pins are used on the desk dock.
2)The USB port actually "locks" the phone in to the car dock, the car dock requires a locking mechanism unlike the desk dock.
3)The pogo pins would cause scratch marks along the back as the pins drag along the case as you slide the phone in and out of a car dock.
4)The pins on the dock would wear out because of #3
5)What is wrong with the USB port?
The phone is easy to get root on. All issues are AT&T, the phone in EVERY other region is a breeze to unlock.
My gripe is weird data issues, where you sometimes need to give the phone a kick (eg via airplane mode toggling) to reset data (3g, 4g or wifi).
This was been improved dramatically though the updates but is still a niggling issue that sometimes crops up.
Also originally I disliked not having a hardware menu key and being forced into the Android 3 dot menu thing. Ofcourse HTC listened and fixed that issue in an update.
When you say sound is great are we talking about the same phone? Can barely hear my phone speakers from the back seat of my car.
That and spotty service/data issues are my only gripes on this phone.

I think I might be having the same issue as you. Does the camera app just freeze immediately and crash? Then says cannot connect to camera when you try to open it again. Happened to me on AOKP Milestone 2 (rohan said it was an issue in the mainline AOKP), but now I've run 3.18 RUU and flashed the latest CM10.1 nightly and had the same issue.

This only occurs after you have modded the phone, so you can't blame HTC for this. Factory reset from bootloader works fine on stock phones.
The way to secure your data is very simple: Don't factory reset from bootloader. Its been mentioned in countless places. So if you wiped your backups, its your own fault for lack of proper research.
Research? Lets just try and read before quoting...

I would expect this kind of blasphemy if I posted a dumb video on YouTube, but the fact that this is a dev site full of "professionals". I posted a comment against my better judgement to try and find answers or suggestions about my phone. The first response is that
"This isnt the place for that" And then 2nd response is
"Why did you buy the one x, you should have known about these things"
First of all I dont think its constructive to rip someone down for a post when clearly alot of people are having the same problem. And I wish I would have found an honest review of this phone before I bought it. I wish I could have read my post before buying this phone. But for some reason Im a black sheep (to a few) for giving my opinion on very important flaws that anyone should be concerned with. I love HTC and have 6 devices prior to this one.
Im not sure who (the 5th reply) twist....? works for and to make statements like never having a storage issue and dont mind the internal card.? I never said anything about the storage. I am commenting on the fact you cant remove the sd card just to make sure the data is secure. And I would love to have a number of how many people use a car dock or computer dock.?? Maybe this guy works for a manufacturer/...///??
I always carry an extra battery and Im not the only person who does. To act like that is unreasonable is just ridiculous.
Of course not all phones are perfect Of course! Why would anyone feel the need to say that...
I love my ONE X It just annoys me that I cant take pictures of my little girl with it. Or store any important data on it. Ive had at least 5 people contact me about the camera issue and are having the same problem.
This last reply to my review and concerns and wanted suggestions takes the cake.
The last comment clearly says that if "you want to secure your data then dont do a factory reset from the boot-loader. It only happens on Modded phones". I have 6 HTC phones and none of them wipe the complete phone to include the external sd. NONE... I wanted to know if it was possible to lock the sd storage or "trick" it to thinking it had an external sd and dont wipe that. If you dont know the answer then fine. I dont see how that is irrational. And I dont think anyone comes to this site because they want to get information on "never modding or rooting there phone." This site is kinda geared towards people who enjoy learning and doing cool, great and ingenious things to make everyone's life better. Or awesome. But to get completely ripped by senior members and the comments being about something other than what I or other members even said is UN professional. This site encourages members to post on General Forumns. I think its 10 before I can move to the big boy pages. But at this rate what could I possible have to gain by it. If I make mistakes or brick my phone then why should I feel like an idiot for wanting people to know why and how it happened to save them a headache? I dont see how typing anymore will stress how childish most of the replies to my posts have been, cannonofcourse out...

I find that external battery packs are way more convenient. You can pick up a 10,000 mah Anker pack for under $50 and it'll charge your phone several times. And it works for any other devices that you might have that charge via USB. And it will work on the next phone that you buy.

So if anybody disagrees with you, its "blasphemy"??? Nobody here is a professional. Professionals get paid. If you mean courteous and polite, I don't see any responses to the contrary. Yes, several of us have disagreed with you. But not in any way that can remotely be considered a flame, personal attack, etc.
I was simply pointing out a FACT that the factory reset from bootloader bug exists due to the phone being hacked. HTC could have not have predicted every way user-implemented mods could harm the phone. You have some legitimate criticisms of HTC and the phone. But the factory reset issue isn't one of them.
You asked for our thoughts. We gave them. Or maybe you just wanted to hear from people that agreed with you?
I'm done with HTC as well if motorola steps up its game with the X but frankly i'll support anyone except samsung. I just want to see android evolve to more than just 1 oem (samsung).
I don't hold the past against any oem. If i like the new phone, i'll buy it.

There is no desk dock for this phone...
For the international version there is, regardless of it's mediocre reviews.
I recently discovered the unfortunate truth of your 2nd point (I'm trying to make my own car dock).
On three and four, wouldn't that indicate a poor design of the phone? (blame the user ala apple's "you're holding it wrong")
There's nothing wrong with the usb port, I just think it would be convienient to both charge the phone and get analog audio out without connecting both the usb and 3.5mm jack.

If I don't leave my phone face down it loses service. I have to restart it upside down and shake it before it will come back.

It's possible. Or it could just be the SIM carrier.

Actually I bought one of the "power on the go" packs from radio shack and broke it apart, replaced the battery with a 3600mah I ordered for my evo on accident. It cost about 8 dollars (plus the cost of the extra battery 12 bucks I think) and it charges my phone incredibly fast and about 3 times before I have to charge it back.up. Nothing worse than hearing that beep noise when your trying to get something done.

I do try to back up everything to the cloud, via Google drive or I have a media server but it always seems like the one thing I needed is gone forever. I just found out the hard way that a reset from the bootloader took out my whole phone. It just sucks not being able to pull the card out and hold it.
That just sucks. I had to get a warranty replacement at one point due to a bad SIM slot, but the AT&T service center swapped it out no questions asked, didn't even notice that the bootloader was unlocked.
It seems like a certain set of serial numbers are having a hardware issue. I hate to go without my phone to get it fixed but I guess thats what I have to do. Thats the price we pay to have it all wrapped up in one little cool device.

I know there are plenty of people that do a fantastic superhuman job. Just hours of searching to find out if someone has or is working on a fix or if I can provide info to contribute seems like so many people just lashing out for no reason.. But maybe Im being defensive.
Thanks
Unfortunately I highly doubt the issues you've brought up can be "fixed".
But...
I'm pretty sure you can change the location of the back button on certain aosp ROMs though.
Using battery case should mitigate the need for a removable battery.
The fact that doing a factory reset from bootloader wipes your phone can't be changed, but a little research on here warns of that in numerous places. And I don't think that's necessarily HTC's fault. It's up to us to educate ourselves about the risks we face when altering our devices.
For instance: TWRP 2.6 has an advanced wipe feature which makes it very easy to wipe your sd card while wiping the usual system and caches. I did that myself just recently, accidentally checked the wrong box and wiped my sd. I lost everything. Without a backup. So many photos of my kids gone for good. But I don't blame TWRP for making it easy to do that. I blame myself for working too fast and not being careful enough.

Did the factory reset thrrough bootloader cause your problems??
If so, all yous gotta do is plug yer phone right into your computer and let windows detect it. Once it finds it, it will send you a window that says something along the lines of having an error with the sd card, from there click the button that says fix errors, and your all set. This happened to me before and I couldnt play music, store or access anything, or use the camera. But now it works perfectly.
And as for the extra battery, the portable chargers provide more battery life with less money. It makes more sense to buy a portable charger even if we did have removable batteries. :good::good::good::good:

Bad battery on I9505. How to check if your battery is bad and more.

Hey guys,
for a few weeks now, my phone has been randomly shutting off at the slightest increase of load. Whether it be loading a YouTube video, playing the casual session of Cut the Rope (Does it count as casual when you complete all three parts with perfects everywhere in about two weeks?) and maybe Plants vs Zombies.
I've not seen similar symptoms on XDA, but who knows when it will hit the next person?
Now, I've searched quite a few forums, such as Android Central, but haven't found a thread similar to this.
I created this thread, in the hopes that it'll help some more people.
Read on if you think you have a bad battery.
Likely symptoms of a bad battery
Serial number starts with BD (Could it be short for BAD? Illuminati! Just kidding )
Phone randomly shuts off completely at the slightest increase of load
Phone refuses to power on again for a few minutes (Turning it back on usually causes it to shut off before/during boot)
The phone constantly looses signal
The phone gets extremely hot when not being used
I've had all of these symptoms and I can promise you it's a known problem.
What will happen if I don't change the battery?
Several things might happen if you don't change the battery:
The battery may explode (Leaving you with either a really big hole in your leg, or worse you might loose some bits and pieces.
The battery may leak and damage your phone irreparably.
The battery may leak and corrode your legs, clothes or what ever encloses the phone.
What can I do?
You can either go to a Samsung Repair Centre or go to your local retailer/provider.
They should cover this under warranty, no matter if the device is rooted or not.
If they don't, you CAN press charges/sue the company/provider.
Why? If they do not replace your battery, they may lead you to harm either by explosion or corrosion.
But that's a last-resort.
What I did, is following:
I called my provider (German Telekom, call them for free from your mobile in Germany under
Code:
2202
) and told them what is going on. They asked me what exactly is happening and got following response:
German Telekom Call Centre Agent said:
Oh, f*ck. Get to your nearest store and get that replaced immediately!
Click to expand...
Click to collapse
which is what I'm doing tomorrow.
You can always use this as a good excuse to buy one of those extended batteries, but why should you? The stock battery is pretty decent.
I'll update this thread when I'm back or on my way back home and let you guys know what exactly happened.
I hope this can help someone with these issues and I can help prevent loosing a leg, or worse, different bits and bobs.
If you're experiencing this problem, and you've done something similar, let others know below!
Edit: I had a Galaxy S III lying around. It's battery fits more or less snug and works as long as you have the back panel on the phone. I'm using it until I get to the store tomorrow.
Yeah....I had the battery problem on S4 about two months ago and Samsung confirm that it was a known issue and that about 30% of S4 battery might be affected. They replaced my battery without any question asked.
See link below as well:
http://www.trustedreviews.com/news/...lems-samsung-offers-free-battery-replacements
Part of the symptoms include swollen battery as well. My battery got swollen to a point that it started pushing my battery cover and the screen out. If you want to know that you have a swollen battery, put it on a desk and give it a spin. If it rolls (with the middle of the battery touching the desk) , then you have a defective battery and you should get it replaced at no cost.
Another symptom is that your battery could go from 100% charged to 0% (phone won't be able to start unless you connect a charger) during a reboot. It will then jumped to about 80% full after connecting your phone to a charger.

Symptoms: serial number of faulty batch; swithing off while showing different load state, heating, swollen battery.
Remedy: replace the battery. By purchasing, visiting the Samsung centre or calling the Samsung Customer Help in ANY country.
So, please, read the linked thread again. Take special attention on the posts: 1; 2; 9; 12; 17; 18; 28; 29; 33; 34; 36.
So far, you were unable to find the linked in my previous post thread, what gives some interesting picture about the ... ability of searching.
Symptoms: wrong as well, because typical for DB bad battery case symptom is that you cannot turn the phone on back again, no matter how long you would wait, without putting the phone to the charger. As well, phone was not going hot (above normal level) no matter, used or not.
Finally, the phone wasn't loosing signal more frequently than normal.
"What will happen section" :, your statement that bad BD series battery will leak, explode, cause the nuclear blast or whatever is unjustified, because the battery is swelling so badly that it would damage the screen much faster. ( further info here and here - I hope you will be able to find the appropriate posts by yourself. If not - please ask, I will help you if your parents are too busy).
Furthermore, so called solutions you tried to provide are ridiculous, as Samsung knows the problem with BD batteries and replaces it without single word, worldwide (examples from threads: Asia, Australia, Africa, Europe).
Last but not least: on the XDA, there is simple set of rules, where one of them states: DO NOT REPLICATE the posts and threads, USE the search button before posting and add your comment to the existing thread before starting a new one if the similar thread exists.
so far, your thread is the 4th related with officially called back by Samsung faulty BD series of batteries.
I don't see anything wrong with this thread and am leaving it open. It provides useful information, which is clearly outlined in the OP, and may cut down on future threads being opened about it.

[Completed] Am i doing anything wrong with BatteryCalibration? ... it doesn't seem to be working.

Hi people!
This is my first thread here on the community, so feel free to tell what i did wrong =)
A couples of weeks i bought a LG G Pad 8.0 (Yeah i should have go for the 8.3 but here on Chile wasn't on stock)
The thing is that everything was fine ... i read all the books i was able to, and played a lot of HearthStone :')
Then i started to get into the Root stuff so i did it with Towel Root
I downloaded the APP did the whole thing and everything was done right (At least what i was able to see)
just a week after the root process, the battery (Or at least the Stats) started to get weird...
The main problem is that whenever i restart the device, even if i let it charging all the night and shows that it is at 100% of his capacity. when boot shows that it haves less than 20%!!
The thing was just telling me that the battery was complete and with a single reboot it losses all his charge?! C'mon! :'/
By my research this has two possibilities:
Hardware Problems or the BatteryStats.Bin get corrupted.
The first one is just ... well not quite possible ... i mean, if it is a "Technical" problem, What was the cause? Why now? ... i can't open the tablet to see the battery but it doesn't have problems with the temperature.
And the BatteryStats stuff... well .... the most "Common" solution is to download the app "Battery Calibration" and just follow the instruction ... well i did it ... Twice! Plus some "Tips" from guys on the internet (Notice the " " )
but it doesn't seem to be working =( ... the main problem is still on my device ... whenever i reboot BOOM! Out of battery! :/ ..... This was what i did:
-Discharge the device until it turns off automatically, turn it on, charge it with out break until 4200 mv (I do it for more than 12 hours but it never send any notification about been fully charged) press the button, unplug my phone and then leave it there with a Super Smash bros match with four player to fully discharge it ... did i did anything wrong? ... i don't think so :/ after the whole process i rebooted the device and it was the same ....
Is there anything that i am missing here?
I've heard about a "Manual" method that consist on fully charge the device then with root explorer delete the bin file and let it discharge ... is that okay? ... Other method is to use the "Wipe BatteryStats" on recovery mode but i do not have that option here.
Well ... what can i do? :crying: Is there any problem with some software? How can i now it? How i can upload a inform about my device so you guys can ses what's wrong? pls help me! T-T LG doesn't have anything on my country and i rooted the phone so warranty went to hell T-T Pls guys! Anything is welcome! T-T
Not Natural English Speaker!! Sorry for any error ... i did my best without google translate! xD​

Batteries and thier cells
If you imagine a square, then split it up into smaller squares (like a spreadsheet)
now forget that, do it with a cube, with equal sized smaller cubes inside, thats sort of like the inside of a battery.
Each box can have a maximum number of Ions inside and as they flow through your phone they change from - to + (they have been used)
this means they also must go back into the battery.
One large problem with them is overcharging and undercharging, where you could (this is only a way to think about it) leave it empty meaning the walls would corrode(think of it as drying out) or overcharge (compressing them, making larger forces on the walls causing them to rupture)
Over time this happens in small amounts and so batteries have a like (some thousand or whatever) Maximum recharges
There is also a chain effect where if some cells split, ones next to it can also split. This could have happened in yours and my advice would be get another battery
BTW all of this is just a way of thinking, I cant remember all the technical terms and do not use them incase i confuse the hell out of people
Before doing this if you like try delete the batterystats.bin (i have done it before, it just made another)

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):

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 ?
Good luck!

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.
Same boat
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.
I do "6.a Sellotape / Scotch tape" + a creedit card cut with this video https://www.youtube.com/watch?v=6_0jzp65eLY#t=73.319872
My LG G2 works fine
