[q] please help! Bricked lg quantum c900 - Windows Phone 7 Q&A, Help & Troubleshooting

Hi all!
I have a hard problem, because I can't turn on my phone!
I used endomondo sports tracker and than had shower in our bath.
My phone was next to me, but wasn't in a water! No water inside.!
Then it turned off. So I tried to start it and successfully.
But about 5 minutes ago, I tried to unlock it and check my text messages, but I couldn't, it was again turned off.
So I gave it to battery charger, but it did not start again. It only shows LG logo and then reboot, again shows LG logo and reboot.
I tried other battery from LG P500 Optimus One, which has the same voltage and the same capacity, but is bigger, but the same problem, battery charged on 90% and it didn't start, when I join it together with connectors on my Quantum.
Please has anyone some help for me?
It was my only phone and I loved Windows Phone, but the new one is expansive for me.
Thank you very much for your solutions.

Try hard reset using hardware buttons.
Sent from my Lumia 900 using Board Express

I tried it without success. Or I tried cold boot, which is the same as Hardreset.
Any other types or help please?

[Q] LG L70 bootlooping! (Not bricked)

Hello!
Yesterday, I was using my LG Optimus L70 a lot so it eventually ran out of battery. I connected it and powered it back up, but then it started bootlooping. Yes, I know you're thinking this is something that's been discussed millions of times but it isn't. It powers on into android and into the lock screen but then powers down and it's the same sequence. I recently charged it to 100% but it's the same problem. It's not bricked or anything, I bet. Also, it shows the battery power perfectly when it's off but charging and everything but it can't stay on in android because it restarts. I need help fixing this. Someone help?

[Completed] A story about my freakishly hard bricked LG G2 F320L. Help needed!!

This is my story that happened with my LG G2
I recently purchased a LG G2 F320L, a refurbished one, from aliexpress(I think this was the biggest mistake of all)
I got the phone, I started using it, used it for 20 minutes and just installed antutu benchmark and ran the app and started the benchmark.
Firstly, I'd like to mention that the phone just got warm, just like other phones, during the test. While the multicore performance test was going on, the phone turned off, all of a sudden (Battery was as low as 9% when I started antutu benchmark). I thought that, it was because the battery was too low to run a benchmark app and turned on the phone back and waited, it just showed me the LG logo for 5 seconds, powered off, ended up with a bootloop. :crying:
I thought that the OS or the bootloader got corrupted and stuck and also thought that I could easily fix it by flashing boot.img or the original .kdz using LG flashtool.
I connected the phone to the PC, it was charging from 9% (That means, low battery isn't the reason for this problem). I waited until it charged till 25% and tried turning the phone on again, but, the same bootloop happened again. I downloaded the .kdz file for my exact model and prepared to flash it using LG flash tool. Unfortunately, the phone came out of download mode (Whilst the flashing was going on) and started with the bootloop again. I really got scared cause the flashing was interrupted indefinitely. I didn't know what to do and I just googled how to enter factory reset mode and I finally entered factory reset mode and chose to reset the phone completely. But, it has happened for a while and continued with the same kind of beat-up (But I was able to enter the factory reset mode later on, though) I was pretty much scared at this time and I gave the phone to one of my friends. I showed him the factory reset mode that was still working, but not useful, and I tried resetting 3 to 4 times but couldn't come out of the bootloop. But, suddenly I couldn't enter factory reset mode and the bootloop became pretty much faster that before (Just showed me the LG logo for 3 seconds and rebooted with the same bootloop). Now, no factory reset mode, download mode, and no charging either.
I got to know that it was a really serious hard brick that has ever happened to one's phone!
I handed over the phone to another one of my friends and he dismantled the phone and tried something, then connected to the computer and the computer detected the phone and QHUSB mode was saying 'Searching Windows update' with a loading symbol. He just stopped it there and told me to take it to a good service center (An expert, of course), and he also told me that I was supposed to ask him, to make the QHUSB mode work.
But, after he gave me the phone back, the bootloop was still happening, just like before, but, instead of LG logo, it was showing some bluish white lines on the 2/4 on the screen.
I haven't got time to go to a service center till date, as they might cost me more than I invested on my phone.
This is really serious problem and I need to enter the QHUSB mode and I need to flash the stock firmware cleanly. Please anyone give some time to read this thread and help me out in this situation. AGAIN, I have used the phone for like, just 20 minutes when it was in a working condition.
So, I request any experts to help me out, suggest me the solutions.
Sorry for my bad English, though.
Thanks in advance.

[Completed] Need Help for LG G Pro 2

I have a Lg G Pro 2. Few days back it got bricked by its own( a crazy fact). That time it was showing QHSUSB_BULK. I figured it out as 9006. Took the phone to a local service shop. Today I got it back and found that nothing had happened to the phone, expect worse. Now it is not detected by PC, only green light blinks for some time if tried to power on. And then everything is black and cold as death.
I think it have been flashed with wrong ROM. Anybody here can guide me with the test points of Lg G Pro 2 (D838 F350) ? So that I can force it to QHSUSB_BULK ? Or any step by step advice to get it up ?
I am in real need of assistance, and thanks in advance for any sort of help. Best Regards.
I would like to mention that the phone indicator blinks for sometime if I try to power it on, as it does on boot, but nothing else is there. No recognition by PC, no presence in Device Manager. Blinks for sometime, stops, again starts blinking... and this goes on at regular short intervals. The area around the camera gets warm after sometime. Everything loops till I pull off battery.
Now, am I missing something ? Is the problem not as deadly as I am thinking ? Is it soft bricked ?

[HELP NEEDED] LG G Flex 2 H959 bootloop

I started having this for quite a while now.
With charger the phone can boot if it's the LG one (tried powerbank, didn't work)
Without charger it bootloops.
==========ADDITIONAL BEHAVIOR============
Device heats up after a while, making the bootloop worse...
The LG logo keeps flashing.... Won't stop until I pop the device open and remove the battery
What's working:
Download mode
System (used to)
What seems to be broken:
Recovery (Boots to recovery but exits it immediately)
Need help here...
Please let me know what could have caused the issue thx
Update: Planning to get a new battery.
LG G Flex 2 H959
Not Rooted, stock 5.1.1
22/5/18: Given up on repair, its irreparable at this stage
I think your battery is dead, i had the same problem, the phone didn't turn on, only with the charger pluged could be used normally. So i bought a battery on ebay and the problem ended.
Oh thx... Will see if that helps
Any more methods guys??? Need them urgently
Anyone?
BTW, is the flashing LG logo a battery issue?
Just to confirm, yes the battery is the issue. My G Flex 2 (H959) experienced the exact same issue, and was fixed by a simple battery replacement. Remember reading several threads about this as well, and most of the then managed to fix it with a battery replacement
Well thx I fixed it
Bought a new battery
The problem returns.
Now the device won't boot, after using for a couple months.
It randomly switched off when I was watching YouTube. Then it started up again and switched off. Pls help.
Note: I can try to start it again when I pull the battery, but same result. Using the NEW battery now.
I feel like I need to start this thread up again.
I have tried using a air dryer to heat the motherboard. The phone still isnt booting properly. Help needed here.
Your Mobo is faulty and defective, same as 90% of all LG G flex 2 released
Yeah, new battery only fixes this issue for like a month, then it returns. I guess its motherboard failure and it either destroys the battery, or isn't able to charge it properly. Guys in other posts here are posting some fixes with heatgun, hair dryer, baking in the oven etc. I baked mine for 220°C for 10 minutes in aluminium foil... and no ... it just killed the motherboard totally. The phone is awesome, but it only works for a year and a half, then you can throw it in the trash. I had my hands on four of these devices, and they did it all. One is still with me, but just recently it started rebooting out of nowhere, so I guess its just a matter of time before this one dies too.
I gave up on fixing mine totally... Let's hope my G5 doesnt face the same fate

LG magna H500f unusual problem

Hi everyone. I'm sorry to post a new thread, but i couldn't find a solution for my problem with LG Magna. My phone was stuck in a boot loop ( hanging on logo) and i tried the worst thing i could google. I used a heating gun and heated chips (both processor and storage) cuz tutorial guy said so, and i ended up frying the board ( because i have no experience with that). So i ordered a new board for cheap and connected everything tried to turn it on, but the phone wouldn't power on. I tried pressing button combinations, leaving phone charging for 2-3 hours ( no charging lights came up, and nothing on screen) i have measured the battery voltage, battery was full. Tried different chargers and usb cables, no luck. I don't know what is wrong with it. Tried connecting to a laptop, but as soon as it detects the phone it disconnects it. The guy who sent me the board also sent his display, so i tried his instead of mine, but again no luck. Won't charge, won't run. I'm sorry for the long post i really need help, this is rather puzzling, so please if anyone reading this can offer me advice or help, i would appreciate it. Thanks in advance.
