LG G7 Dead - LG G7 ThinQ Questions & Answers

Hi All,
While using my G7 Thinq, screen froze & none of the buttons were responding. To reboot the phone, I pressed volume down & power button & G7 switched off. However, while trying to restart, the phone isn't responding anymore. I've tried volume down + Power button, Volume up + Power button, but the phone isn't turning on. I've tried to charge the phone & tried to restart it, but there is no response. Even with the charger on, the phone isn't showing any signs (no activity on screen, no vibration).
I've searched online, there was someone who faced similar issue with his G7. In his case, he was unable to switch off the phone. His battery got discharged in few hours & he was able to recharge the phone & use it. In my case, since phone is switched off, battery may not get discharged for a very long time.
1. Is there a way to completely discharge the battery quickly in switched off mode?
2. Is there a way to reboot the phone?
3. Is there a way to retrieve the data stored on in-built memory?
Before taking the phone to service center, i want to try out whatever i can to save the data. In case service station guys solve the issue, they will surely wipe out the data from phone.
Pls help me
Thanks,
Ankit Jain

Without the phone being on to get the data that requires jtag, but that might be a little out of your league and you will lose warranty.
Try connecting the phone to a computer and see if the pc picks up your phone in a certain mode.
Usually black screen and no sign of power is 9008 mode which its on, but it is stuck and wont switch off

Hi,
I've tried connecting the phone with PC. Its not getting detected. Is there a way around this 9008 mode? My phone is presently out of warranty. I've searched online & haven't heard of many cases like mine. I don't know if this is a manufacturing defect & I should take it up with LG.
I'me pretty much concerned about the data on the internal memory of the phone. In case phone needs to be reflashed, i'm thinking of using a data recovery software to get the data back.

Hi All,
I have taken my phone to LG service. As per them, its processor is gone. All they can do is change the processor, or rather entire motherboard. All data will with it. Moreover, repair cost is more than the new phone itself. I'm pretty disappointed with LG. I don't think I'll buy an LG product in future.

Samsung Galaxy S2 won't boot to main menu, and has seizures.

I'm having a huge problem with my T-Mobile Galaxy S2, and not it won't even completely boot up. The issue had already been around, but never this bad. Usually, when I would use my phone, it would just randomly reboot on it's own. Now, I can't even get to the main home screen or menu. When the battery is inserted, the phone will automatically try to turn on. I'll get the Samsung screen, then the "Samsung Galaxy SII Android 4G T-Mobile screen", then the phone will glitch for a second, black screen, and it'll almost have a seizure from then on. When I say that, pretty much what happens is that the screen will go black, and it'll pulse with vibrations. It'll vibrate, stop for two seconds, vibrate some more, etc. That's all it'll do from there on. It won't try to turn on when I hold the power button, and the vibrations won't stop until I take the battery out. There is no water damage, and there's just normal wear on the phone. I've had the phone since the drop, and for the most part, it's been great until now.
The phone is not rooted, and I have not installed anything crazy. Come to think about it, I didn't really even have too many apps installed on it to begin with. The phone is under warranty, so I had T-Mobile send me a replacement. My main issue now is that I have content on there that wasn't on my SD card, but on the internal hard drive that I find extremely important, and want to keep. When I connect the phone to my computer, nothing comes up because I didn't "connect" it to the computer as you normally would have to do from the phone, before the extra drives pop up on the computer. Without getting into the main menu and manually connecting the phone to the computer so that the drive will pop up, what can I do?
I've tried taking the battery, sim card and memory card out, letting it sit for a few hours, and plug it back in, but it does the same thing. The battery isn't bad, because it plugs into the replacement phone that was sent to me, and works just fine. I've also plugged into my additional batteries, and it does the same thing. I can't do the "hard reset" where you hold volume up & down, then the power button because what happens is the phone will restart itself before I can get to that point. I tried it when I was on the phone with T-Mobile, and the associate at one of the retail locations tried when I went to get a loaner. I've tried hooking up the phone to the Kies software, but it won't recognize the old phone. It will recognize the new one with no problems though.
I am in no way am I well versed with the process of flashing it or installing different things on the phone. I just used it casually for phone calls, texts, web, and an occasional game or app. I'm just stating this so that if there are any specific tips that anyone could recommend, please if possible, explain in a bit more depth, because after I posted my title, I found the related threads, and most of the steps that were recommended to others that had problems sound a bit foreign to me. I just really want to recover the photos and documents that I had on the phone before I send it back to T-Mobile.
These are the threads that I've somewhat referenced so far:

http://forum.xda-developers.com/showthread.php?t=1813866
I can't seem to find anything with the same symptoms as my phone though. If anyone could let me know, that would be great. I just really want to get the content off my old phone, it's just extremely important to me. I'll be waiting on any replies. If you need and more information about what the phone is doing, or what I should try, please mention it. I will try to update this as I get replies, since I am supposed to send the phone back pretty soon. Thank you in advance.
You have a stuck or broken power button. Stick a toothpick or something into the power button whole and take out any gunk if there is. If that doesn't help, then you have a broken power button and you have to get your phone fixed.

So from what I understand your phone does not boot up to the home screen at all and you are trying to recover all the files from the internal storage? I've been in the same situation as you, although, with my previous android (Samsung Captivate) and I know how hectic this situation is...
If you can enter recovery mode still without the phone restarting itself and if you're willing to flash a custom rom that should help you get into the home screen to recover your files, as it shouldn't remove anything from the internal storage (just as long as you don't format the internal storage/system in recovery).
The phone 'seizure' you are experiencing may also be caused by physical damage, such as the internal memory becoming defective (hopefully not the case).
You mentioned that you can't turn on the phone with the power button and the phone only turns on when you place the battery... that's the same thing that happened with my old phone and it turned out that I had to disassemble the phone and clean/replace the power button. After that the phone turned on like normally again, however, I had to flash a new rom for it to properly boot up.
As a last resort, if you can enter 'Download Mode' via button combo or usb jig you can use Odin to flash a stock rom. However, the files you originally have in the phone will be removed, which you definitely do not want. But at least your phone will possibly work again.
At the moment, I don't think there is any way to recover the files you need from the internal memory without being able to boot up the phone to get it connected to your computer. If you do manage to boot to the home screen, but can't connect your phone to your computer. You can always do a wireless transfer to a cloud based storage such as Dropbox (you can use the android app) and just transfer your files from your phone through that.
I hope I am of some help to you, if I find any other solutions I'll let you know. Good luck!

[Q] SM-T700 Froze, Powered off - Soft bricked?

Hey guys,
Appreciate it if you could spare me some advice on how to proceed.
So I was watching a twitch stream and all of the sudden tablet froze, and the audio froze as well causing a large super high pitch noise, I hard-reset the tablet but instead of resetting it just turned off, I started to browse the forums and found that a combination of (POWER + VOL UP & DOWN + HOME) would reset the tablet,now what this did for me is turn the tablet on but it was stuck in SD CARD Mode, back again to the forums, read that letting it discharge fully and then it will be able to be charged and turned on, that worked tablet was back doing some various tasks no video again and then boom freezes again same symptoms except this time I couldn't get it to go to SD CARD Mode its very finicky after trying at various times in the day I finally got it to work, same process except this time as soon as it turned on I went into recovery factory reset it to stock, worked a bit longer this time only installed chrome, and it froze again (don't think it was chrome) , rinse repeat and I flashed the latest firmware with ODIN worked fine, I've gotten to the home screen ran through the "factory new" set up and it turned off of me again.
I plugged it in let it charge, came up with battery icon 5% 10% ect, then I left it for a while, I came back and I cant even get it to show the battery percentage(tap power) let alone turn on.
I'm fairly sure that eventually I can get it turn back on but from there I don't know what to do.
TL;DR - Tablet Froze, Hard Reset, Froze again - Rinse Repeat, ODIN to latest STOCK firmware, tablet worked for 5 min before turning off again (plugged in), present situation
Any ideas as what to be causing the freezing and how I could remedy it?
Also sometimes when it froze it turned itself off without me hard resetting it.
Thanks its been driving me insane,
Please do not hesitate to ask me to clarify or provide more information so I can help you help me.
Maybe youve got the loose battery connector problem?

What would you suggest I do, submit it to warranty ? Will they disregard the fact that knox has been tripped if its a hardware issue ?

I had the loose battery connector problem, but the symptoms do not sound the same as mine. I could get mine to boot up, but the screen would flicker and a few white lines would appear before it would reboot itself. I actually started a ticket with Samsung and got the packaging label but, upon further reading, realized that I was pretty much SOL after tripping knox, and didn't want to risk the chance of getting charged for just sending it in. If it is indeed the loose battery connector, you should be able to remove the back cover yourself and fiddle with it. Ultimately, mine needed re-soldering, and I was able to find a local electronic repair shop to do it for me for cheap.
Good luck!
UPDATE: I've managed to get into SDCARD MODE yet again, except discharging seems to get out of it, but once I plug it back in it doesn't come up charging it just black screen, until I hold some buttons and arrive back at sdcard mode. Good times.
Trying various things to get it to boot..
EDIT: Appreciate the insight Squez, I want to exhaust all the other options before opening it myself, if Knox didn't void the warranty to some degree, opening it up should put the final nail in the coffin.
EDIT2: Good news, sort of, tablet isn't dead! after numerous attempts with charge SDCARD mode, discharge, It finally start to charge properly and I managed to get it to boot, worked for a few hours then I left it to charge, and went to sleep, woke up and wont turn on again, but I am in SDCARD Mode again but need wait for it to discharge from presumably 100% ....
[What do you mean Sd card mode? DOWNLOAD mode?
Also no need to let the battery drain.
Just press VOLUME DOWN(not volume up) and POWER together then hold until it restarts.
This is a hard reset and will ALWAYS work unless the device is hard bricked. It is the equivalent of a battery pull.
I continually see here and there incorrect information regarding key combinations, even in so called guides, this forum is even guilty!
Here is what works on the 10.5lte, as far as I'm aware its the same for all versions, indeed pretty much any Samsung device.
HARD RESET:
VOLUME DOWN - POWER.
Hold until the device restarts.
DOWNLOAD MODE:
HOME - VOLUME DOWN - POWER.
Hold until the device boots.
RECOVERY MODE:
HOME - VOLUME UP - POWER.
Hold until the device boots.

I should of posted a photo earlier but here is one I found on google of same screen: (check attachments)
Except UP KEY and DOWN KEY don't do anything, its just this screen, if you attempt to hard reset ect, it will just reload this screen, hence the discharge, then plug it back in and hope it begins to charge "battery icon appears". I have gotten it to boot like this a few times.

Yeah its strange as.
I'll have a look at that, thanks.
EDIT: It just finished discharging and now I am on the battery screen.. Usually once it charges here I can get it to boot, what I'm curious is what on earth keeps causing it to freeze up, because in download mode and twrp (gone since i flashed stock via odin) it wouldn't freeze at all, only have issues with it once its booted or charging. I installed a logcat earlier hopefully that should shed some light on the situation,
EDIT2: Well another very interesting thing, the official Samsung charger wont charge it, only works if I plug it into pc or use a non-official charger, strange thing is nothing is wrong with the samsung charger or cable since I can charge my phone fully from it. These have to be some of the strangest symptoms.
EDIT3: Only works through USB port on PC for now, non official charger comes with red X on battery once booted. I assume you can work around this once rooted but that's for another time..
EDIT4: Charge through pc to around 2-3%, boot device, plug into official samsung wall charger and it begins to charge properly.
EDIT5: Hooray back to step one, trying get into SDCARD Mode, same thing happened left it overnight and it wont turn on or charge anymore.

i am pretty sure the HOME - VOLUME DOWN - POWER. puts the 10.5 into the sdcard mode.
my tablet is doing very similar to sunb3ar findings.
have had it come back to me once from sdcardmode.. (let if go flat and starting charging then it would start via normal buttons)
it crashed not long after that. it got stuck in sdcard mode again, but this time none of the drain flat, put on charge has worked.. just blank..
fyi- we try to put it in RECOVERY MODE, but it does not work when in this crashed / sdcard mode state
i even disconnected the battery and then plugged back on charge.. nothing..
today i tested the battery volts, 2.8v , for a 3.8v i thought that was ok. i attached my RC lipo multi charger set to 1amp 3.7volt charge, direct to the - + on the battery- got it up to 3.5v, plugged back in, put the charger on- the sdcard mode (most life it has shown in a week).
still not coming up with 'battery' display to say its 'turn-off and being charged'. just the sdcardmode might disappear and return..
i am currently adding mode charge to battery... will try to HARD RESET next.. since i have not tried that combo yet..
HARD RESET:
VOLUME DOWN - POWER.
Hold until the device restarts.
edit: i took it off 'direct' charge, battery at 3.7volts.. then plugged in normal charger, i got a 'battery symbol' but it had the lightening bolt, not a %.. so i unplugged and reconnected to my direct charge to give the battery more volts. i am surprised that the unit seems to think a battery with 3.8volt as it specs seems to not be like with volts not much lower than 3.8.. could be time for a new battery if we can get this thing to restart

[Q] Z1c suddenly died/bricked (stock lollipop)

Hi guys,
I'm new to this forum and haven't rooted or installed custom roms before, but maybe you can halp me with my problem.
The other day i was on my way to work, at home my phone was working just fine, but when i arrived, it was dead.
I put the phone on charge for the rest of the day, but nothing happened, only a dim flashing red light. Tried to reset in all possible ways.
I charged it with a usb power meter and it draws only about 20mA intermittently...
When connected with the sony bridge for mac software the phone isn't recognised at al. I tried pc companion in windows XP (in bootcamp).
and then the phone keeps connecting and disconnecting over and over.
I don't want to sent the phone out for repair, because there are a lot of pictures and other private documents on the phone and i can't erase the phone myself. Who knows what happens when the phone is repaired.....
Is there a way to get the phone back to live without erasing?
Thank you very much

open the sim card slot you will find a small red button (Reset button) there next to the sim press it until you feel 3 vibrations then don't turn on your phone charge it until full then turn it on if it didn't then again press the reset button and don't turn it on , go to pc companion>support zone>software update>repair my phone . and this will be your only hope and i'm afraid you will lose all data on internal storage

My S4 mini won't turn on, doesn't vibrate, can't launch recovery or download

So a few hours back I picked up my phone, but it didn't respond. A few minutes earlier it worked fine, and now it just seems dead. I cannot launch recovery mode or download mode. The phone does not respond to me holding the power button or something, there is no vibration and no visuals on the screen. Removing the battery and plugging it back in does not work. Leaving it charge for a while does not work. (assuming that it even charges). When I plug in the phone into my PC via cable I hear a sound that something is connected, but it doesn't show up on 'My PC'.
What do I do?
The same happened to my sister! Nothing worked, probably the motherboard died. Used it at leaset for spare parts for my other s4 mini. Especially the LED panel is so precious, it's cost is like half the price of the phone.

Yeah, likely. I ain't a geek or sth, but the same happened to my sister. Was looking for a solution for hours, but it's probably some random variation in voltage or sth that burns some part on it and then it dies. You don't have to crack the phone etc., it can happen randomly.

Wouldn't a broken motherboard make my PC unable to make a sound when it's connected? Also, when it's connected to the PC and i hold the power button for ~15 seconds, it disconnects. This would mean that the power button still functions

Then it's deffinitely NOT completely broken. A dead MB would definitely NOT identify the phone in the PC.
Did u try entering Download mode & connecting to ODIN, trying to load FW again?

I cannot enter any mode. Pressing volume up or down + home + power doesnt do anything. How do I connect to Odin, and whats an FW?

FW = Firm Ware i.e. software that is flashed onto chips. aka ROM.
But if you can't go to download mode you can't flash stock ROM again. So Yes sounds likely some component has failed or maybe just a bad solder joint, a short, etc) which is not allowing power up,( either way you need someone to fix hardware & install stock using jtag for you, probably not worth the cost on our old phones in most countries. but if you can buy a used phone with eg a damaged screen or other problem you may be able to get 1 working phone by swapping parts eg power board ...
The same happened to me last august... I posted here, but no one ever helped me https://forum.xda-developers.com/galaxy-s4-mini/help/weird-bricked-gt-i9195-stuck-black-t3619023 i just think that it's some kind of programmed obsolescence, my phone was 4 years old and it just shut off and never light up again after closing a simple call... F*** Sammy and their timers!
Just happened my nephews phone. Was intermittently responding to buttons and now not at all. PC detects it and shows as "HS-USB Diagnostics 9008" in Device Manager.
There are a couple of guides online for using applications on the PC to interact with the phone using this device ID, but it seems to be mainly focused on LG phones. Anyone know if there's anything that can be done for Samsung devices?
The exact thing happend to my S4, it suddenly turnd of while im using it, did anyone find a solution?

Nokia 6.1 seemingly hard bricked after reboot

I have a Nokia 6.1 TA-1043. I have not unlocked the bootloader, and it runs the default operating system (Android One, probably Nokia flavoured). It has gotten slower over the years, and it had a period where it crashed every now and then (sudden reboot). Anyway , some days ago I decided to reboot the phone because it was slow, and it instantly shut off. After waiting probably 20 seconds without response, I decided to hold the power button down to force it. I don't remember exactly what I did, but after trying to again hold the button down to turn it on again, it vibrated as usual but the screen remained black. I then most likely tried holding volume + and power to force another reboot, unsuccessfully. I then tried holding volume - and power to enter download mode. It might have vibrated, or I might have touched the cable making me think it vibrated, but nothing happened. I pressed some random buttons after I think.
Now, the phone does seem to charge. It gets warm when I plug in the charger. I've searched for hours on different forums, and some people say that their phone was magically resurrected after the battery went completely flat after few days. I have tried plugging the phone a bit and testing every button combination (including volume +, volume - and power at the same time) for a few days now. It's dead.
The phone is also seemingly not recognised at all on my windows 10 PC. Haven't tried on Linux.
I have a few theories:
1. The phone simply hard bricked itself due to some hardware failure.
2. I bricked the phone by (blindly due to screen being blank) entering recovery mode and unknowingly factory resetting the phone and shutting it off mid process.
3. The battery is messed up? Some suggest deconnecting the battery. It would require the use of a heat gun to even open the phone though.
I've seen some people suggest entering EDL-mode either by shorting some pins or using a modified USB-cable. However, that would either require opening a phone that isn't supposed to be opened easily, or plugging a modified USB-cable into my computer, nether of which seem safe. I've also seen people mention that whatever needs to be flashed in EDL-mode must be signed by Nokia, which I can't do obviously haha.
It's probably time to move on right? Has someone managed to get a phone in that state to work again?
Hi i can explain some of your theories:
The first one: It's impossible to make the phone hard bricked itself.
The second one: Factory reset is only wipe your data not the OS itself so if you Factory reset and force reboot it should get in to Download mode and you need to unlock bootloader to reflash the ROM. (I'm not in that situation so I'm not sure it's correct or not.)
The third one: No, I don't think so.
That's all so if you have any question ask me. Thanks!

Thanks for replying My phone seems unresponsive, so I haven't managed to get in to download mode, at least not visually on the screen. Also, my phone is not recognised on PC, making me suspect it's not really turned on. I also tried holding volume up + power for 40+ minutes by stuffing it between a few books when making dinner haha, and it still didn't respond. Would you move on in this situation?
