LG G2 (AT&T D800) bricked itself - G2 Q&A, Help & Troubleshooting

So there I was, browsing the Slick Deals app, when the phone locked up, turned off, and now it won't do crap. Decent charge on the battery at the time, ~90%. Stock ROM and rooted for over a year with no issues to speak of. I got the phone on day 1 (Sept 2013?) I'd taken care of this phone better than any previous to it. Always in a protective case, always with a screen protector. Never dropped, never left in a car or in the sun. My plan was to go 3 years with this one I liked it so much. Well so much for that idea.
If I hold down the power button long enough I can get it to boot some of the time. Recovery mode and download mode are not options, just won't do it. It did the whole 15 drives thing when plugged into USB once, but there is no consistency to it. I read several threads on how to unbrick the phone, but the whole Linux install and img files are little over my head to try.
I went ahead and ordered a new battery for it, just in case that's what's causing the issue. I was told if a cell in the battery flips out it can cause the phone not to work properly. At one point I had the phone charging while off and could see the charging screen. It got to 95% and never any higher. Managed to boot the phone for 30 seconds then it shut off again. I quit messing with it after that.
Could it be just a battery gone rouge all of a sudden, or do I have bigger problems? I hate to abandon this phone, but I don't want to spend any more money on it to fix it either. I bought a used Nexus 5 off a friend for a song to get back up and running with my SIM card, so I have time now to work on the G2. If I can resurrect it, the Nexus will serve as a nice backup phone in case of future disasters.

Something bricked my phone.

My phone, which I've had since waiting in line on March 24th quit on me today. I'm not sure if it was the culprit but, I installed a program called Lookout mobile security last night 5/6. When I started the phone this morning put it on the table, got some java and when I got back nothing..no buttons working...ok..no problem tried a soft reset...nothing..ok now starting to get worried. pluged into power source..boot up screen. whew..low battery. then blank, a few seconds..boot up screen AGAIN!..by now I'm in full freakout...Attempted to calm down.. didn't work..thought ok..most everything is backed up..lets do a hard reset..didn't WANT to but anyway! Did the hard reset .. Still had the same problem...Had to pinch myself HARD to make sure this wasn't a nightmare. Went to the TMobile store and the associate put me in touch with technical support (they were Super) Going to give me a new phone but, have to wait until next Friday to get it...and then tweaking and rebuilding it to what I want...I should have been ready for this coming from an iphone...All it takes is one $%@# program again, not saying it was the one mentioned above but, one with a malicious code or something that destroyed over five weeks of building a phone from scratch. Sorry about the rant... I still LOVE this phone. .
so you couldn't even boot it in to the bootloader? wow! Maybe you should flash HardSPL before trying to install that program again as there is far less chance of bricking it if you have HardSPL installed. Even if the rom gets completely stuffed, you can still boot it and reflash from SD.
All I can recommend is install a ROM via Micro SD card and maybe doing a Task 29 before you reinstall a ROM

If those don't work then I don't know what else to recommend
They want my old phone back once I get the new one so, I'm going
to let them have it just as I turned it on yesterday. Let them
find out what the problem was created by.
I was about to install that "lookout" software...but after reading this I might as well hold on.
did you leave it on the charger overnight or did you just turn on your phone in the morning.
if you didnt have it charge all night, maybe all you needed to do was leave it on the charger a little longer before starting it back on.
i noticed that some phones with a dead battery and on the charger will sometimes not stay on until it has gotten a minimum charge on the battery.

Setting up the new phone shouldn't be a big deal if you did actually backup; just stick the old microSD in the new phone and run whatever backup app you had on the card.
I put it on the power supply and it is in the constant loop of
the first screen that appears. I am going to seriously look into
HardSPL. Thanks to all the good input from everybody.
Well now even customer service is at a loss. They cannot phantom why why two separate phones have the same problem. While I had CS on the phone we went thru various senario's to try to get the phone to operate properly. I even had them give me a new SIM card and that did not work...I suggested the problem might be the battery as it could have gone bad. You guys think the phone is playing hard to get--try to find a replacement battery! No stores within a 20 mile radius had one in stock....! Needless to say they are going to ship me yet another phone. plus a new battery and hopefully it will take care of the problem. The sales associate did a hard reset on both my old and the new phone without results so that unfortnately is not a viable solution. Now I am in the game I hate the most........The waiting one! ..

^^ what the op says above. This happened to me (and my gf as well) on our HD2s. The first time (mines) this happened, i hooked it up onto my car charger and immediately tried to turn it on.. it would go onto the TMO screen, but quickly shut down and loop. After realizing I may be trying to jump the step, I unhooked it from the charger, took the battery off, put it back on, hooked it back onto the charger and let it sit for about 10-20 minutes charging. Turned it back on and viola! It wasn't a brick.. I can almost guarantee this is your problem.
But I may be wrong lol...
So, now after 2 replacement phone sent to me, I find out that
it was the battery all along. Problem is that after the second phone
arrived and I had the same problem I called customer service and
explained it to them....They said a battery would be sent next day
air...Ok...called the next day and was told that the rep never sent
in the order...Long story short....I've almost been without my phone
for two weeks now and, all I need is a frelling battery.
Problem is there are NONE around me..I've tried every tm store in
the area, All radio shacks batteries plus...you name it....
I am being sent a battery UPS ground...could take 7 more days.
Just took the battery from my fiance's phone and it works
so, right now I would pay a ransom for a battery just to have my
phone back!
I had to do a hard reset after downloading that lookout trial.
at this point I don't know what caused it..Has anyone ever heard
of an application causing the battery to go bad?...I worked really
hard to keep the battery I had in good condition.. I hope UPS
delivers soon!
This is odd I have used Lookout Mobile on my phone since I had it. Mind you not had it for long, since April but still its never bricked or did anything that hindered the phone. I maybe another program.

Possibly bricked forever - Stuck at Sumsung logo endless reboot

Stupid thing is that I can do everything to it aside from getting it to boot all the way to work! I tried reflashing OEM roms and I tried custom roms. They all work just fine and it just won't boot all the way. I can turn it on and off, use format option, download mode and magldr. I keep my sim out and memory card. Before this all happened I always used OEM OS. Last thing I did was check my bank account, close the browser and click the power button to turn it into sleep mode. Few weeks ago I did have an issue with it for a day. It kept turning on and off constantly boot to random points. Mostly to the AT&T screen. It would boot all the way rarely and I got it to stay on a couple times for about 10 mins to copy all my stuff from it. Is it possibly something to do with the hardware being a POS and Just crapping out for no reason because cell phones are poorly made expensive bricks?
I've seen this issue across the forum several times. Unfortunately, just one case seemed to "return" to life, without understanding the reasons behind the "lapse".
What I can suggest you can do (and feel free to disagree) is get in touch with Cottula (creator of MAGLDR) and see if you can help you. You can send him the phone, maybe he can analyze it and get something out of it.
GL, mate, and if you find a solution, I'm sure other folks here would be glad to hear it.
Ahhh ok thats what I figured. I browsed a bit, but most of what I saw is people couldn't do anything. I didn't see anyone saying they could do as much as what I can do with it. I'll try your advice and see if maybe he could help. I took apart the phone to see if maybe someone came loose, though I saw nothing. Clean as a whistle. What I think maybe happen is it burnt up finally. I notice at times it would run extremely hot, mostly when I'm talking on it for more then an hour.
Well, for your sake I hope it's not burned out (hardware issue). I hope it has some software component that's screwed and that has a chance of being investigated and maybe fixed.
Also, the getting hot while talking/browsing for periods more than 30 min it's a known issue. It's however supposed to be quite warm, but not actually really hot, if you know what I mean. It it however possible that exposing the phone to higher temperatures to cause hardware issues.
In any case, I wish you good luck. Who knows?
I gave AT&T a call to see what they could do. The software warranty is 6 months past and she wasn't able to override anything that much passed over. Though I was able to get my 2 years wavered and get a early upgrade. So I got myself a Xperia Ion. I'm happy I don't have to put up with a flip phone for another 4 months. lol
I tried working on my focus a bit more playing with zune and other programs I found. Though I don't see it coming back to life trying all the different ROMs. I would think to make it work again is to re-flash the actual phone bios itself. Just like a computer starting it still uses DOS then loads the OS. I don't know how a phone works to much, but I'd assume same process. Something to do with the root-root of the phone telling it to be stupid and not boot properly.
Another note, where is the best place to sell this to get some money out of it? Screen and other pieces of its hardware are 100%. Should I try ebaying it?
I had a similar issue, last thing i did was removing the SD card before re-flashing the MGLDR and custom ROM

My phone took a bath...am I screwed?

Ok, so I was hanging around with a friend today. While running, I accidentally dropped my keys. While trying to pick them up, my phone fell out of my pocket right into a pond. I immediately picked up my phone (less than 3 seconds) and tried to shut it down. What I didn't notice was that the phone already turned itself off so I accidentaly turned it back on /facepalm.
The LG logo briefly appeared for a second, then it turned off. Still, the rest of the phone seemed operational (the notification lights, the speaker etc.). I immediately got home and put the phone in a bag of rice. i only removed the sim tray since the battery is sealed and I had no idea how to open the phone without losing my warranty.
So my question is : am I screwed? I was personally thinking of the following scenarios :
1.Leave it in the rice for 48 hours. If the situation remains unchanged, try to send the phone back and pretend that it happened out of the blue. The fact that I initially bought it as a used phone (while retaining the 2 years of warranty) might also help...
2.Go to a service. Now this would mean 2 things :
1.automatically void my warranty, since the phone will be opened
2.there's a big chance that the service wouldn't be able to do anything so I would automatically be left with an unoperational phone AND with no warranty.
Also, I've heard that even IF my phone comes back to life, the components will still be affected in the long run...
I honestly don't know what to do. I really like (liked...) this phone and the fact that I payed over 600$ for it (and bought it as my birthday present) is that more painful...
Any advice would be greatly appreciated!
Sorry to hear that.
As far as I know the most phones have an indicator for wetness. And I know that even without an indicator they can see what happened. I think your warranty is gone.
As you bought it as a used phone, I would try to sent it in for a repair even if it powers on and see what happens. If the fix is free or not too expensive I would do this.
If its to expensive but everything works, i would try to clean it with alcohol. There are guides around how to disassemble the phone

Bricked My 6P, But Not Sure Why/how.. Any help is appreciated

I'm pretty lost on this one and after hours of searching, have not the slightly clue how (or if) to fix it...if it can even be fixed.
Past few days I've noticed the phone randomly rebooting, some of the times it says my battery is 0% when it's almost full. Today I went to go wipe it and reflash Pure Nexus. While wiping and flashing it, it ended up in a boot loop. I've tried everything to get the phone back up and running. I've tried attempting to flash different ROMs, the stock images (tried T and Q), doing a hard reset, factory reset. Literally everything under the sun that I know to do or have looked up.
Right now the most my phone will do is turn on, shows the Google screen, the reboots and repeats. Sometimes when the phone is off, I have to hold the power button for a minute or 2 to get it to turn on. Still, can only get in the bootloader, but can't get it to boot further than that.
Any help is appreciated, I'm at a loss on this one....and phoneless. :crying:
Pretty weird, if nothing works you should flash stock images, lock bootloader and RMA.

I also tried to lock the bootloader and re-unlock it, with no luck. Called Google and they weren't any help, least outside of what I've already tried. I'll be calling Huawei tomorrow when they open.
As of now, it seems when I unplug my phone, it just turns off. I plug it back in, it goes into bootloop (without me hitting power button). Sort of wondering now if the battery just took a dump?
The phone started acting funny every since I tried to Android N. I'm going to attempt to try flashing N again, just for kicks.
I found a USB charger at work. While not a fast charging one, it was enough to allow my phone to boot up. Apparently there is something wrong with the battery some how. When it booted up, it showed I still have 48% of battery left so I took it off the charger. About 5min after booting it shut down again. Now that it's on the charger again, it'll boot back up and now shows 1% of battery.
I can't figure out for the life of me what the deal is. Looking like I'll need to lock the bootloader and RMA it back for warranty and get a properly operating phone. I'm curious how quick this will happen to get a working phone? I'm up for an upgrade through Sprint, think at this point it's best to go get a new phone to use in the meantime since I have no old phones to use in the meantime. If Huawei gets me a new phone within 14 days I can take the new one back and rock on with Nexus. Kind of sucks, but just my luck.

That's exactly what you should do. Most probably the battery is dead or malfunctioning. Charge it with that spare charger for a few hours, then restore stock and lock the bootloader. Finally, turn it up for RMA.
I never had a single out-of-the-box issue with any of my 5 Nexus devices. I hope the replacement that you receive will be up to the satisfaction.

Thanks for the confidence. I'll do just as suggested and return it.
I'm up for an upgrade, although I have to do online so I don't have to pay an extra $30/month for a phone I'll sell after getting my 6P back. I hate sprint not letting me do it in the store, such a PITA. If I do online I can just get the discount and sign a 2yr contract which is fine with me. Any idea if they will ship a new phone so I'm not without a phone for week(s)?

Sorry, but I never had any experience with an international carrier like Sprint, so can't say. Someone here would be able to answer this better than me. :highfive:
Thanks for the quick reply. I'll call Huawei here in a few and start the process and find out. Fingers crossed they will ship a new phone, even with a temp hold on the money while I send this broken one back. I'll post what I find out, just in case anyone else is curious and searching for the answer.

Note 4 wont turn on, "cannot boot normal" and "downlaoding target, dont turn off"

Note 4 wont turn on, "cannot boot normal" and "downlaoding target, dont turn off"
Its a Note 4 SM-N910F, Android 6.0.1, BB N910FXXU1DPE2, kernel 3.10.40-7733605 [email protected] #1
i feel I have tried everything... History:
Phone has been working fine for a year, upgraded to 6.0.1 no problems about 2 or 3 months ago. no new apps installed. Last week it started getting very laggy, keyboard strokes took for ever to register. I thought, ok, time to to a factory reset to blow out any old cobwebs. Did it via the menu. However the phone froze midway thought. I left it for an hour and then pulled out the battery. I popped it back in and it performed the reset without me having to press anything. Cool, thats good I thought.
Now I was going to change the battery, so I powered off as normal and put my other 2 week old original samsung battery in, and it would not power on. After a few reinsertions it powered back on. I though i have to do another reset. So I tried, and it would not reset. It just died. I cant restart the phone, it dies. If I shut it down normally. it wont turn on back on, I have to take out and reinsert the battery multiple times, holding down the powerbutton between to discharge. this can take up to 10 tries now. Sometimes it will go th the unable to bot in normal mode and "downloading , do not turn of target, but it will stay there for ever, more than an hour.
Every 15-20 tries it would turn on, let me get in via pin, only to start freezing up within a min, and then die again. Somewhere I read that a guy hada similar problem, and he used wakelock and that worked, on level 4. I managed to download that and used it, and hey presto, it works!
Now I had to power down the phone for a reason, and it took me about 30 min of battery and powerbuttonholding before it managed to boot up, and I was quick enough to start wakelock on level 4.
It wont boot in to safe mode, it wont boot in to recovery mode, it wont boot in to the factory reset mode. Its the same with either battery, and different cables.
Any ideas what i can do here, or what could be wrong? I havent gotten it wet or banged it.
I am having the same exact issue on a N910A. Phone was functioning correctly and in December it started getting really laggy. Performed various resets, purchased new battery. Still laggy. Up until two weeks ago the phone was slow but now it will not power on . The phone will not charge as well.
Mine did same, 6 months old, not rooted stock firmware. Locked up yesterday, couldn't do anything. Pulled battery and restarted. Samsung logo comes on screen goes black for android boot then it hangs with blue led flashing. Nothing I do gets it past that point. Tried safe boot but it doesn't fully launch with correct button combo and volume up. In the end I re-installed firmware using Keis. All went well, everything as per youtube tutorial. Except one thing, at end of download phone didn't re-start. Still can't get it to boot, any ideas?
Edit: Lock up didn't coincide with any new apps being loaded or updates of existing. Only change was a week ago which was an automatic update of the stock firmware (Lollipop)

are you still under warranty? i sent mine to a samsung center, the guy recognized the problem as the motherboard, said I wasnt the first. That was 3 weeks ago, they are STILL waiting for the parts. They say the Samsung factory are way behind with repair parts, etc etc. I am hoping it will go under warranty. Ill update when I know!
I've been having the same problem that started yesterday morning. I've tried a few different solutions but nothings worked, I get the feeling that my phone is dead and I'm not in warranty either. I'm going to approach Samsung but my guess is they will want more than the phone is worth to repair it. I've read about so many people having the same issues, its horrendous engineering on Samsungs part considering how much their phones cost to start with

Your guess is probably correct and I totally agree with you. I seriously think manufacturers do not want their devices to be problem free for more than two years. Probably why they have stopped making phones with batteries that simply pop out.

Definitely...surely it couldn't have been that hard to make a device with a battery that was still removable on the newer phones. It's frightening how many forum posts I've found with people having their phones just brick out of nowhere (and that's just the note 4). I've given up trying to fix mine, I've tried every method I could find and nothings worked. I can only assume that this problem is simply the motherboard of the phone not working anymore. I'm not even sure what phone to buy now but it certainly won't be a Samsung.

If you do not care about the camera thera are a lot of rather affordable options which can be tossed in the bin when they start malfunctioning and if their warranty has run out. If you care about the camera being as good as the Note 4's than the range of phones you can buy is quite limited.

If you are able to boot it into Download Mode then you should Download Stock Rom file for Galaxy Note 4 from Sammobile and Flash it through Odin..
Everything will be OK... ?
Unfortunately, SAMMOBILE does not have the SM-N910A firmware.

I think the camera on the note 4 is absolutley terrible. I might even go so far as to say the pictures are unusable. the applied noise reduction renders everything splotchy, colors are off and its not sharp at all. and Im not talking dark conditions here.
Anyway, my phone was repaired under warranty and is back to working as it should. It was indeed the motherboard, so if you have the same troubles I had, those are your best bets.
I don't think replacement via warranty will be available. I will attempt to power into download mode and verify if I can get it back up and running. If not, a good ole paperweight.

Sounds like the problems I have: with my first N910F: started with lagging apps / freezing, then random reboots now and then, eventually giving error messages when booting. Finally, now it will only start after the battery has been out for at least 30 minutes, but hangs on error message. When pulling battery out and putting back in it, wont give a single sign of life. Since I was just out of warranty it has been lying around, and I bought a second hand N910F for replacement, sadly its starting to give the same errors too and is just out of warranty too (its currently still working, but with freezes / reboots / and already a event with boot error).
I read It could be memory chips or some power chip on the motherboard, appears to be a common problem. So.... Last month I bought a new motherboard on ebay (chinese delivery, 80€). Received it last week and put it back in; phone is back to life. (putting it in is a very simple task, with iFixit teardown / guide)
Anyway, I love the Note 4 for performance / size / looks, and have been Samsung fan for a while, but this recent breakdowns and information that it is fairly common, has diminished being a fan fairly quickly and I guess the Note 4 will be the last Samsung device for a while after this new motherboard breaks down as well

My phone is also random Rebooting
It also shuts down at 25% of battery remaining, Have you also faced similar issue?
Download the app "Wake Lock" and run the Partial Wake Lock option. Apparently the updated software impacts the CPU. For the restarting issue, put it in the freezer for a couple minutes. You may have to take the battery out once, but it has worked for me every time.
This looks very much like the issue reported here:
https://forum.xda-developers.com/no...-error-fix-t3434335/post72944466#post72944466
There are temporary fixes (wakelock), but ultimately this is a harware issue, and the fix is a new motherboard.
I think that underlying it is a problem with heat affecting the eMMC chip or its connection to the motherboard.

Hey can u pls get me the stock firmware for n910gddu1dpb4
You might find this interesting. Since I couldn't get mine to power up at all, I called Samsung tech and they quoted me $75 to fix it and they would pay for shipping. I figured it was better then getting another phone off Swappa. 2-3 weeks later i get an email that they are repairing it under warranty at no cost to me. I got a refurbished phone since i know my IEMI number was different. they didn't explain why. Anyway, I got lucky i guess.
