lg g4 h811 dead - T-Mobile LG G4

I had a phone for the G4, but it was working normally and then signed me in the water. Of course, I took the battery and put it on the rice for two days, but now it does not work. There is no trace of life in it. It does not charge and the computer does not recognize it, but I noticed that when I remove the battery and reinstall it Pressing the power button does not work, but I hear the sound of a slight vibration. What is the solution, guys? Help me

The slight vibration may be the chip powering up but there could be other damage elsewhere on the motherboard or other circuits that is preventing the phone from starting (if the water is short-circuiting the circuitry elsewhere it will probably short out and damage the phone further. I would suggest leave it alone, do not try power it up for a few days (3-4) longer, maybe leave in the rice again, and see if it comes back to life.
By the way, these phones are very cheap on eBay provided that you are able to buy and have it shipped from/to your location. I recently bought one for $20 locally and another spare for $48 on eBay, have total of 4 of these, just love these phones except the outdated OS.

Red light of death fixed!!! (sticky???)

I think I just figured out how to fix it!!!!!!! I was tinkering around and got my red light brick to turn on!!!! I'm not sure exactly what fixed it so here's everything I did-
1. Removed the storage & sim cards.
2. Took off the backplate.
3. Removed the battery.
4. Bent these 2 pins up a little bit:
5. Put the battery in at an angle, so that the power leads were connected, but the metal shielding plate on the back of the battery was not touching:
6. Hit the power button (with the battery still "halfway" installed) Bam, green light of life.
Somebody please confirm this. Meanwhile I'll be copywriting this process so anyone who performs it owes me 10 bucks
So my replacement Tilt isn't working either, so they're overnighting me a third one. In the meantime, I haven't sent back my original (RLoDed) Tilt, so I thought I'd play around with some of your theories.
skuzz said:
Another thought I had. After the tilt goes into red brick death mode, has anyone tried plugging it into power, battery installed, and then holding down power+camera(all the way) and then pushing in the reset button on the bottom? This may trigger it to go into flash mode - although I kinda doubt it'll work. Worth a shot! Might be able to reflash it back to life! Holding down power and camera while it boots is how you manually force it to get in the Red/Green/Blue firmware flash mode. If it let us do that much when the device bricked we might have a snowball's chance in hell of getting them working. I didn't think of trying it before I returned mine tho. D'oh!

I didn't know what to try besides installing the battery and SIM card and trying to push down the power, camera, and stylus buttons (I knew I was doing it correctly, because I had to use this to return my second Tilt to factory specs). No response whatsoever! This thing is deader than a doornail. Except for the red LED, of course... that works REALLY well whenever it's plugged in.

I appreciate your enthusiasm, but the only thing I can confirm is that this did NOT work on my RLoDed Tilt. Tried it several times in various ways. I think you just seriously lucked out!
As such, I'd also have to vote against stickying this... for now.
Best of luck, all... if not actually in fixing your RLoDed Tilts, then definitely in avoiding the $500 service fee if AT&T discovers we voided our warranties.
alright i will confirm this too....my phone was truely RLOD..... i did the same thing that these guys did just jammin the battery in and out and it "jump started the phone"
exact process used
Moto Razr charger
hold down power button
"bounce" battery on and off the contacts for the battery a good 100 times or so
green light apeared after the red light started to flicker a little bit..... tis as if you were giving the phone CPR or something
im not going to call this a fix all i know is that the phone was RLOD and now it is working....battery is at 54% right now and i will post back in a bit to see if it has risen at all....
no smell arising from device
running origional rom but have had other roms on there (alex's)
hard SPL still installed on device
SPB phone suite is the last software that was installed on the device
reg tweaks installed as well, the usual ones no sms, hsdpa enabled blah blah blah
that is about all i can provide....the unit was on the computer overnight charging....when i woke up it was RLOD....and i was sad....i did have the ATT store replace the battery for me as well dunno if that had anything to do with the issue...
in the time that it has taken me to write this the battery is now at 55% so it is charging.....on wall charger with MOTO razr charger
ok lets take a little closer look at what happened within the past little bit....
after gettin the device all up and running it was behaving very oddly.... it would go through multiple attempts to connect to the data network for various reasons....after showing that it was at 55% on the charger it went back down to 54%... i pulled it off the charger and took it into the other room to do something......within 10 min it was down to 46%....now having a data connection my blackberry connect should have a valid network connection....but it did not... not sure why...
the best that i can conclude is that it was trying to connect to so many things all at the same time that it exhausted its self that fast....
so the question is how many people out there that have RLOD are running the BB connect software on there devices and have made REG edits to the data connection time outs and the HSDPA mod availability
editing those settings together may confuse the device and make it think that it has to connect to too many things at one time....
just another thought process that i thought that i would throw out there...
here are some things on the my device that would use the DATA connection and automatically initiate the connection on the device rather than you opening a program forcing it to connect such as Internet explorer
GPS update
HTC home weather tab
SPB weather tab
Blackberry connect
SPB insight....RSS Reader
text messages going in and out....my phone sees quite a few of those
Edit/Delete Message
There have been a few other people who have now fixed their RLOD's. Confirmed it was done by messing about with the battery. If you have revived yours, please post your method in here so we can compare them and eventually pinpoint the fix. Thanks.
i had the same prob..took out the batterly wiped the four contact points on the phone (might of pushed them down or up) and put battery back in and worked..
I believe sWuRv was onto something. My Tilt had the RLOD today. I tried everything, even what he suggested above to no avail. So I called warranty and got my replacement on it's way, express shipping waved and all. So I decided to everything I could think of to try and get the thing back on so I might be able to back up my data again.
I started fooling with the battery, like sWuRv suggested but I moved it all around at 45 degrees or so pushing the power on button. I noticed while it was plugged to the USB with red light on that every now and then the red light would flash when I moved the battery so the contacts moved (while holding the battery at that 45 degrees). I started getting the light to go yellow but it would not stay. So I unplugged from the USB and kept trying it while pushing the power button. It eventually started and I was able to back up to my SD card. One thing I can tell you is that this process caused the phone to get hot and smell like electronics burning a little. There is definitely a power problem inside.
I have no idea how or why this worked but it did. I think I will still take the replacement even though I have to figure out how to swap my fancy invisible armor clear protector skin.
I'll try and update on whether this phone dies again or what until I get the new one.

I tried messing with the battery in a variety of ways for 30 minutes with no sucess. RLOD stayed solid.

Holy shoot............After bouncing my battery up and down about 40 times my phone came to life!!!!!!!!!!!!!!!
Reseating the battery and/or sim/storage cards is hardly a revolutionary procedure. Its Cellphone 101.
you guys are LIFE SAVERS. I have been on this forum for about a month now and I finally found a reason to post. I haven't posted because I always find my answers. I just wanted to thank everyone, as I have been on the phone with Amazon.com (where i got my tilt), went into an AT&T store and was on the phone with HTC tech support ALL day trying to resolve my red light issue. Unbelievable that all I needed to do was give it some "battery CPR":
UGHHHH. Well i found reason to make post #2. The fix lasted less than 5 minutes.
this did not work for me
These stories remind me off all the bad batteries/no powerup of my Motorola Q and those of others. My mother is on her 4th Q and I know its the battery, but the store just swaps out the whole phone. I've seen batteries last as little at 2 weeks, especially if let run down to empty at any point.
My questions are, is this just a bad battery problem? Does anyone with RLoD have a spare battery to try? If these batteries fail in the shorted condition, will they over draw power from the phone and mess up the charging circuit?

I certainly don't believe it's a bad battery problem. I had 2 spare batteries, fully charged with separate docking charger - none of the 3 batteries made any difference once I got the RLOD.

Very good, thanks for the insight!
I finished a call yesterday and then dropped my phone on to the pavement cos I was a bit drunk... Anyway this caused my phone to go from working fine (all be it with pants battery life) to just flashing the red light. Fixed it today. I tried the methods prescribed in this thread without success although I did not persevere for very long. I then put a spare battery in to the phonea and bingo the orange light comes on, phone boots up and it's now happilly charging. Note that I charged the old battery for several hours before trying the fix. Pity nobody seems to know what the problem actually is. I wish HTC would let us know....

I had a similar problem with my old iPAQ hw6515, and a Motorola V3. The contacts on the battery don't spring forward as well on an older phone as they do when it was new. I shimmed the battery. I did this by taking a business card and holding it against the opposite side of the battery from the contacts I traced the battery's profile and cut it out. I scotch taped my new shim to that side of the battery, then re-inserted it. This forces the battery up against the contacts better and in many times resolves inoperable phones, failure to charge, and spontaneous rebooting issues.

My replacement tilt (first one had a bad USB connector) died Sunday.
Had it on the charger, looked down, red LED. Back of phone was pretty
warm. Pulled the battery, SIM, memory card, slammed the battery onto the
battery contacts rapidly 5-6 times, put the SIM, memory, battery back into
it, and it charged up. Did a hard reset. Battery was 100% charged, I turned
it completely OFF when I went to bed. Got up, battery was 0% drained!
Red LED again. Did the rapid thingy with the battery again, orange charge
light came on.
Called at&t warranty replacement. When I told her I had a red LED, she didn't
even ask me to do anything else. She just asked for the IMIE number and shipped me another one.
Maybe the 3rd one will be the charm LOL.......
I'm beginning to think that HTC doesn't stand for "high tech computes" but
"high tech CRAP"....
Maybe you guys got the margin of error productions? I know its really unlikely that you could get them again after a replacement but it is possible, and it maybe your computer. What do you think could be making this things go crazy? Overly protective anti-virus, I know, I know but it could do things secretly and screw around like mine does and wont let me into sites I have been on before on the same app no changes . . . Well I hope you luck.
ok I just tried everything you guys said, but it didn't work for me
so as some of you have stated it must be the battery, so what I did is put it between my hands for about 1 minute and put it in and it worked again!
really weird... must be the heat?
well hope that helps the research
Cheers

BIG problem

i got this free carjack to usb adapter and i tried charging my tilt in my car with the cord that plugs into the computer.
well as soon as i plugged my phone in it turned off and i couldnt turn it back on via the power button.
after a few different combinations of removing the battery and reinstalling it and soft resets it now works... but not as it should. i try charging it and the battery doesnt gain any juice and when i unplug it it still thinks its charging. so at the moment i have about 30% battery left and i took it out so if need be i can do a hard reset on the phone, because it does turn on now.
does anyone have any idea what went wrong and if my phone is alright?
i have fairly standard software upgrades i can try to list if it is needed
You might have fried your charging hardware inside the phone, which as far as I know is not covered by warranty. The problem is that many free carjack to usb converters are of very poor quality and either don't give the right voltage (5 Vdc) or the right current (minimal 1 Amp necessary for Tilt/Kaiser while free chargers usually only give 0.4 or 0.5 Amps). Please use only quality brandname chargers inside the car. These cost only 20 buck max which is nothing compared to the phone-replacement.
Note: I use a carcharger from Garmin which came with my bluetooth Garmin Mobile XT receiver and so far no problems.
so basically im screwed?
Well, if the hardware in your phone is busted, then you're screwed. Check your warranty if it's covered but I guess not since it states that only HTC aproved accessories may be used and I don't think your free Carjack-USB converter is approved.
Or you could go to Squaretrade.com , purchase a warranty , and then process a claim shortly after (1 month). I use squaretrade, never had to process a claim but at least I have piece of mind.

..same here I have Square Trade for my Kaiser and other things. Used it once for a camera problem with no hassles. This could help after as mentioned 1 month membership has gone by. I purchased accidental damage protection too... it has to be new and less than 1 month old to qualify for ADP. ADP covers your butt for any problems.
If your lucky maybe only the battery got damaged, like the overheat/overcharge circuity inside the battery, I am guessing it has that inside the battery pack..and at least on my Kaiser without the battery installed and the phone plugged in it wont even turn on to test without a battery. In any case I wish you good luck with that, I've seen other peeps here that had the same problem, do a search of this forum and see if they had any luck.
Not to familiar with the whole Squaretrade thing? Could someone further explain this?

Repairing water damaged phone

Hi,
i send my phone down the river and probably killed it. backplate was broken and charging lid as well, there is no warranty any more.
i dried it for a week in a box covered with rice and tried to turn it on afterwards. No reactions on buttons, but after i plugged in the charger, the LED got red and Display turned on showing the "Sony" Screen. after a second or two LED and screen went black and the procedure started again. and again. after a few repetitions i put the plug away. so i didn't charge the phone any longer than ~5min and have not plugged it to the PC.
first question is if someone has encountered the same symptomes and can give a statement of chance to revive the phone. Second one is: Where to start? there are lots of guides to disassemble the phone, thats not a problem i think, i have all the tools i need and a little bit technical knowhow. I want to start checking the battery, pretty shure its dead. afterwards i want to check the board for signs of corrosion. but then?
grateful for any tipps, especialy want to know whats the real death sentence for a water damaged phone. after i have seen the screen working i thought main functionality is there and only the battery died.

I would leave it plugged in and see if you can build up any sort of charge in the battery. It seems that changing the battery would be an obvious first step, if you can get enough charge in the phone to fire up the mainboard, then you will see what else needs to be changed. leave it plugged into a charger for 24 hours.
Do you want to repair it to salvage what data is on the phone or is it financial reasons? tbh the cost of new mainboard and battery, plus replacement back screen is going to be more than a second hand phone off ebay. If it's a science project then bravo, not enough people try to rescue thier old kit from the bin, but I'm saying there are easier options than pulling it apart.
Having never pulled a phone apart myself I can't really offer any more advice, but you might want to drop @Chamelleon a PM, as he regularly contributes with hardware fixes and knows his stuff.
its more about financial reasons, data is all backed up. Buying a new phone should be the last option. i want to repair it cause i like repairing things and i want to make clear that the phone is absolutely dead or not. i dont think i would buy a new mainboard/display/battery if i am not completely shure that this will fix all problems. in this case id rather buy a new phone.
i am a bit afraid that if i charge the battery for 24h and still have a circuit on the motherboard i will completely destroy it.

A week in rice in a warm place means there's no moisture in the phone.
The phone won't be damaged by trying to charge the battery and you need to find out if there's anything working from a full charge.
I recently had a waterdamage too. I took it apart and i saw that there was some corrosion on the board by the display connector. I put the mainboard in isopropyl alcohol (you can get that in the pharmacy). I carefully cleaned the affected part with a soft toothbrush and let it dry for a while. And now my phone is back a life and everything works as it should
Good Luck!

Well, turns out this guy is right. Phone is working after charging. Vibration is dead and there are some residues of the wather in or behind the display, but nothing else i can find now. i think i will still disassemble the phone, and clean all parts. Maybe i will replace the vibration motor, but i think i can live without one...

[Q] Dead phone, with a twist

This One M7 had been my spare for close to a year. I replaced the screen, camera, and back cover to make it whole again, and everything worked great for a couple months. Unfortunately, it completely died one day while I was using it and the device has shown no signs of life since... until now.
Actually, it still doesn't really show any signs of life. No amount of button holding has been able to elicit any response whatsoever. No charging indicator light either. I've tried leaving it sitting for several months, but this too has not changed anything. I finally opened it up today to check on the battery connection and reseated it. Still nothing.
The one and only response that I do get is recognition on my computer when plugging it in, where it shows up as an "MTP USB Device." Nothing shows up in Windows Explorer though except an empty CD drive.
Any ideas?

you bricked it, maybe flashing RUU can help. if it will not help you can then use JTAG, it can help to flash firmware on dead boards. you can find JTAG on eBay.

Do you have multimeter to check voltage on battery? it could be battery problem, or maybe connector on motherboard is damaged? check for scratches on board (on traces).
It shall be tried

I'll try to measure the battery voltage this weekend. Aren't the pins a little small to test with standard multimeter leads though?
0volt multimeter test
I finally got around to trying to measure the voltage of the current battery with a standard multimeter. I got absolutely nothing, which means that I'm either measuring it wrong, the leads are not sharp enough, or the battery is dead. Has anyone else ever had any luck testing this battery with a multimeter?
Going for it!
I tested another, similar, battery by multimeter successfully, so I suspect that it might just be a case of bad battery (at least). With that and the fact that I had a Galaxy Note 2 battery fail earlier in the year, I'm going to jump in and buy new batteries.
Rather than just trying to go cold turkey and install the replacement, I'll test it with the multimeter and then hook it up pre-install. If the phone powers up, then (and only then) will I go through the massive hassle of replacing it. We'll know one way or another next week when it comes in.
Humongous Tinfoil Catamaran!
Just to follow up, I did end up buying that battery. Definitely not "new," but as long as it's in decent shape, it should do the job. While the multimeter test revealed practically nothing, (same as before) the phone did spring to life with the charging indicator as soon as I plugged it in to power. With that, I've charged it up and will be fully testing the phone next weekend. If everything checks out, I'll start the long & annoying process of replacing the battery and hopefully have a fully-working One once again.
Here's to Change!
FIXED!
Just to provide some closure, I can say that the battery replacement was a success! The vibration motor is totally dead (despite being plugged in adequately and not seized) and the casing took a beating from the repeated re-entry attempts, but the phone is now working once again. I suppose I could buy another replacement back cover to really finish the job, but will probably just leave it as-is for right now.

Water Damaged, Bootloop Huawei P10

Okay. I really need help here guys. So long ago I had water damaged my phone and I got it working again. About 2-3 months later the battery started acting up and showing percentages in 10s and soon after could only use it when it was plugged in.
Now, whenever I plug it in it immediately shows the Huawei logo and starts to boot up. Which I don't like because I remember it used to show a green battery circle before. But nevertheless its in a bootloop now. The weird thing is, I can't use the volume up button method. I don't know why. It just carries on.
Maybe I should wet the power button with water if its been held down causing it to immediately boot up when plugged in? i dont know.
If anyone could guide me or suggest what to do I would honestly be so appreciative. Thank you so much!
Could be a hardware issue. Water is causing corrosion to metal parts and if there is still a bit water inside your phone the corrosion can damage parts of the hardware. It's risky to use the phone without drying it completely. In the most bad case the battery can be shorted by the water which can cause a battery fire or explosion.
Bring your phone to a repair shop if you're not able to open it by yourself. But I think there's no hope anymore.
You should've let it dry completely before using it again.
Don't put water again to parts of the phone.
If you're able to open it, disconnect the battery and check the logic board for corrosion and water.
If there's still water you can remove it early by putting the logic board on a piece of cloth and wait for a few days.
You can also try to clean corroded parts with pure alcohol and cotton swaps.
Get a new battery to be safe, check if the old one is misformed. If it's so, don't use it again - NEVER!
Li-ion isn't a funny thing, it can be very dangerous.
If there's a shortage inside the battery or it's physically damaged it can burn out. The technology is based on cells. If the cells are getting shorted each other, a chain reaction starts and inside the battery the current flow can get so high that the battery start burning. It stops when every cell is damaged and the voltage is 0 - it's hard to extinguish such fires. There are many videos on YouTube.
So don't make fun with this, just do something if you feel safe in electronics. If not, go to a repair shop.
