[Q] Sudden Hardbrick

My phone hardbricked for no apparent reason, and I'm not sure what to do. Battery was at about 50% yesterday, it turned off and wouldn't turn back on. I did a soft reset, and it turned on. I watched it go as far as the logo and then had to walk away. When I came back, the phone was black again. And it hasn't turned on since. No logo, nothing. I've tried a soft reset, plus multiple other reset combinations. I plugged my phone to the computer, I get the normal connecting 'ding', but then it says that driver's device cannot be found.
I'm running stock firmware, no mods. No history of battery issues (except the normal slow decline). I've had the phone for a year and three weeks, so I'm out of warranty too. I called T-mobile and they said it sounds like a hardbrick and are willing to switch it out for $20 since I'm out of warranty. I can't do that since I'm out of the country for the next 1.5 months, so I was wondering if anyone out there had any suggestions on what to do or why this even happened?
Thanks!

does it respond to plugging in to charge? im not 100% but if its responding at all when it gets plugged in its not hardbricked only softbricked so go from there. when i hardbricked my first s2 due to a corrupt kernel file i flashed it would not react to anything at all. complete dead weight

U stated that when u plugged it into ur computer u got a ding then says driver device not found. Sounds to me that ur not in a hard birck when I bricked mine I didn't even get that. Check out the link it well help.

on my t989 enjoying sith3, thank u to all

Thanks for everyone's help. I ended up sending in my phone to a Samsung service center (while I was in Korea). They confirmed that it is a hardbrick. They opened it up and said it looked like there was a short and it fried the motherboard. They couldn't tell me what caused the short--they said maybe some water got into the phone through the charging port, but I know that isn't true... I had it plugged into an old power strip and maybe that's why? :crying:
Either way, I was told my only option was to get the motherboard replaced which would be $200. I told them no thanks and that I'd just get a replacement phone from T-mobile for $20.

sounds like another " I swear i didn't do anything.. it just happened" story.. classic..

I know my story sounds unlikely, but it's the truth. Isn't this forum around to help fellow users? I have no reason to lie here. I actually take very good care of my phone and (after almost losing a laptop to a water spill) am extremely cautious about liquids around my electronic devices. You don't have to believe me since I'll get my phone replaced regardless. I just thought I would share the information in case someone else ends up facing the same problem.
Even now, the only cause I can come up with still is the old power strip frying the motherboard. *shrug* I would love to hear any other explanations.

[Q] Hard bricked, but...

Hi there, I hard bricked my Tab S 8.4. No reaction to anything I did (key combinations, let it charge for hours, stuff like that). Don't know how it happened but it just crashed to death shortly after installing an inofficial Lolloipop build from here. I don't think a ROM can make a device not turn on at all. My money is on hardware failure.
Anyway, brought it in for repairs (willing to pay since I knowingly voided the warranty). Got the call yesterday. They said the software had been tampered with and they can't repair it. I objected that the software won't break the hardware but no dice. They won't even do it for cold hard cash.
BUT: To see the 'illegal' software they HAD to get the thing to turn on . And if they got it to turn on somehow, so can I. Or... am I completely wrong there and they have some magic fairy dust?
Any ideas on how I could accomplish what the repair guys could obviously do? There is no important data or anything on it so I'd be happy with Odin mode, CWM or whatever.

I kindof had the same problem, but got mine repaired.
May I ask where you send it to for repairs? Was it Samsung or a local repair shop that told you they could not fix it?
And did they send it back to you? Kindof weird they won't fix your device after you say you are willing to pay for it.
Depending on where you live, Samsung covers a lot of 'problems' in the first year of the standaard warranty.
As for turning on the device..
What options have you tried yet?
If you connect the tablet with usb to your pc and turn it on, does it get recognized?
And if so, as what?
But if your screen doesn't turn on, you're probably going to need repairs anyway.

Over here you bring it back to the shop where you bought it. They will try the simplest solutions in house but usually send it back to the manufacturer. I think the information came from Samsung directly. Another theory I have is a simple lie. They tried it in house, nothing came up, some clever guy screamed 'CYANOGEN!' and they all high fived (I have a vivid imagination )
As for turning it on: tried everything. It's not only the screen, it did nothing at all. No signs of life whatsoever. Of course the PC wouldn't recognize it since it was turned off.
I'll pick it up tonight. Maybe whatever they did to see the software tampering stuck and it will at least go into Odin mode. I can work from there.

But it you think it came from Samsung directly, then I would advise you to contact Samsung.
Here is a link from an article where it states that Samsung covers bricked devices, but only the first time. (Dutch article, GTranslated english)
I have no idea if this also counts for where you live though.

Magic dust it was. Got it back, dead. Came home a minute ago, put it on the charger. Lo and behold, the battery appears. Device turns on too, boots Lollipop goodness. 0 per cent battery but hey. Whatever they did, they obviously did NOT realize they solved the whole problem with just their diagnostic :laugh:

It simply reset itself after the battery completely died. Black screen and no response doesn't mean the device is off.
As soon as they switched it on they would have seen knox had been tripped.
Sort of did you a favour by telling you it wasn't bricked.

I had the same sort of problem i connected my tab to my laptop and used the recovery mode key combination then my tab came back to life

Sorry download mode not recovery mode

Comforts me while ROM developing that the only reported case of a hardbrick was here - and the battery just died.

LG G4 NOT stuck in bootloop but not booting past LG logo [goes off]

Hi all, ok tonight/this morning at work while on my break i went to do my usual thing of having food and watching a tv show via cartoon hd about 2mins in and my phone switched off.....now i thought it was dead so plugged in the charger but no led light, or screen on to say its charging.....i did a bit of googling and find out about the bootloop thingy buuuuut mines not looping, its swtiching on to the LG logo [i did the bootloader unlocker thingy etc so it says tha in the top corner] then it goes off.......i also get pulsing blue led lights too.....if i press, hold the power button after i get nothing, i have to take the battery out and then its rinse and repeat

Hi,
Same thing happened to me today. I was taking a shot and it switched off and same scenario.It seems that we had encountered an bootloader brick in which our device enters in some special bootloader mode in which when you connect it to the computer in the device manager it shows up as Qhsusb_bulk. I read the whole internet and there is a similar brick with G3 the guys were able to fix it. Even there is a tutorial on how to do this which I think is applicable to our device. I was able to install the required drivers and etc. but there is one big problem - I followed the guide and came into one serious problem - we need a special mbn file so we can recover our device and the sad thing is nobody on the internet doesn't have it still. There are many people like us who got selfbricked G4 and cannot fix it without this file. Please if somebody can help us please share the file so we can fix our devices. THANK YOU !
Link to the g3 unbrick guide

ive seen lots about the bootloop issue, but the thing is mine isnt doing a loop [i have to take the battery out/ pop it it back in, to switch it on then after 10-20 seconds on the LOGO it turns off

on G2 you get security boot error phone is detected as QHUSb_BULK. on G2 the fix was to enter download mode. in G2 vol up then plug usb.
using TOT method and flash tools . flash stock firmware fixed my soft brick.
not sure about the file you mention, maybe you do need it..

I have the issue. I don't do anything special but my phone reboot and stuck on lg logo. But now my phone doesn't want to boot. Sometimes he detect when I'm trying to charge it but often not. Yesterday I boot on download mode and recovery but today it's impossible... I think I have some hardware issue ? Or software with the bootloader...
I don't know how to fix that without access to download/recovery mode :crying:

Same here. Sometimes it boots into recovery/download but most of the times it doesn't. It's a hardware problem I think as LG officially confirmed that there were problems during the building proccess of the first G4 series. I don't want to sound bad but soon or later all phones built before october last year will get into bootloop. I was hoping it won't happen to me - I'm very light user with only light standart apps with no games and other heavy stuff, so the problem wasn't caused by overheating by heavy multitasking. Anyway it happened and I'm pretty sure it's harware related but if somebody can provide the tot and mbn files I will be more than happy to try the g2/g3 unbrick method. The main problem is that these files are not available for h815. I found on other forum tot files for other variants than h815 So if somebody have the tot filesfor h815 please share so we can try to unbrick our G4. Thanks!

same thing heppened to my g4 this week. i called lg last night and they agreed to repair it. i'd just gave them a call.

I sent mine for repair today. I hope they will agree to repare it even that it's with unlocked bootloader and with rooted custom rom !!! What you think ? Will I have problems with them because of that ?

Happened with my phone as well. It was rooted so i was hella scared if they didn't accept my phone. But soon they told me phone's motherboard has gone bad and will be replaced. Got my phone with a brand new motherboard after a couple of hours.
P.s. all your data will be gone

So the same problem just happened to my lg H815 with unlocked bootloader, am really f***ed without my phone, gonna call LG UK tomorrow, anything in particular I should say? also looking for solutions I saw many people are starting to have this issue now too - any official comments from LG?
P.S. if you have an LG G4 you should start backing up all your data now

This literally just happened in the last 15 minutes to me as well. Random reboot right after I woke up the phone and now stuck on the LG splash screen. Light user here, never did anything with the phone that would have heavily stressed it physically or computing-wise, so I also concur it's an inevitability for earlier runs of G4 phones.
Luckily, I backed up everything through TWRP last Thursday by chance because I was updating Xposed to the latest version and swapping to a faster 128GB microSDXC. At worst, I might have lost a handful of unimportant text messages.
Not worth the time to try to figure out any cheap fixes myself, I just got done submitting a repair request to LG.

I ordered LG G4 H815 and I hope to not see any kind of these issues

Phone won't turn on

Hey guys, phone was working fine this morning, a bit slow, but working. Went to check it at work and the screen wouldn't come on, nor would it turn on so I put it down to a dead battery.
Got home, plugged it in and no light was showing to show it was on charge, took the battery out, tried it that way as well, still nothing.
I'm going to assume the phone has just died on me or needs a new USB port (possibly) Any help is appreciated. I was on Resurrection ROM, LP (I think)
Any help would be great!
Edit, just plugged it into my computer and my computer picks the phone up, but it isn't shown in windows explorer, odd. Still no screen, charging or LEDS either.

USB it says "QHUSB_BULK" Assuming the phone is bricked now, no warranty and it's bootloader unlocked so it'd be void sadly.

Help a Hardbricked LG G5

Okay!
So I bought an already used LG G5 Sprint LS990 and it was locked.
I took it to a store to unlock via a software and it worked after putting my sim.
Then, the phone became very hot and went off. It refused coming on. It was more like a hardbrick. It doesn't come on. No recovery or download mode. No display on the screen when I plug in the charger (the phone just feels warm after a while). Also, when I plug it to the computer, there is no connection sound and I checked device manager, it doesn't show anything. No Qualcomm HS-USB QDLoader 9008 or BULK whatever...
I got tired of trying. So I abandoned the phone for about a month.
Last week, I plugged it in again and omg! It showed the battery icon and it was at 0%.
I left it to charge to 100% and I put it on. It got stuck on the Sprint Splash screen and went into a bootloop.
I removed the battery and reinserted it. Now it won't come on again. It's back to being hardbricked.
I even bought a new battery just incase but it didn't work.
It still doesn't connect to the PC.
I don't know what to do.
Can anyone please help?
