LG magna H500f unusual problem - General Topics

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.

[Q] Bricked? Or just battery acting up?

Hi guys
I've had the Sensation for about 3months now, and suddently yesterday it stopped working. It wont charge, no LED's and wont start at all. There have not been any waterdamage, drops or rough use.
I've read a lot concerning similar problems on this forum, but none of the solutions has worked for me.
What I can tell is that I have tried after searching the forums:
- SDK, ADB and try to reboot the device via USB-connection (device not found)
- Win7 (32bit) can't recognise the phone (asking for drivers which are not found in HTC Sync, QHSUSB_DLOAD)
- Trying to enter recovery mode (Volume Down + Power up)
- Charge the battery overnight
- Charge the battery with a plastic-piece covering the two middle pins on the battery (As suggested in a thread)
- Battery out for 1min and then put it back in and start up
Neither of these worked, so are there any other good ideas? Or is it bricked?
Hi guys,
i have exactly the same problem, already have tried all of these solutions, nothing have worked for me... Please help.
PS:sometimes my screen lights up <black totally, but lights up>... when plugged into usb cable or charger... but not now anymore...
I have bought this phone in china, there is S/N but i guess that here in UK i cannot do anything about it since HTC's warranty is not global...

Also keep note of which recovery you are working off of. There have been charging issues with certain recoveries.
Yeah, I read several threads and posts about recovery-issues... Unfortuantly I cant check what version I got myself, as it wont start up at all :/

I would suggest to go to a store that sell's the Sensation and ask if you can test one of their batteries out to see if your phone has either a battery issue or something else. If you are stateside, of course try a tmobile store, but without knowing where you are located, this is a hypothetical at this point.
I know I had an issue with my Nexus1 not booting up from a kernel I had flashed. But I noticed my charging led was flashing three times and then stop. I researched this here on xda and found that it just needed to be put into recovery again somehow. I ended up just plugging the phone into the wall and remove the battery. Try to power it on there and then reinsert the battery and try the power + volume down button. That time it booted for me. But again, this was for my Nexus1 not with this phone.
same happened to me, sent to HTC and had main board replaced, lcd, flex cable etc. the driver the phone looks for is the equip HTC use to jtag... I am not sure if this is a hardware failure or boot corruption...but even though it was s-off via alpha rev it was that damaged they didnt complain... i say hardware failure. the thing is even when i have s-off i didnt change the rom. I have a riff box on order so if this happens again we can surely see if this failure is software or hardware..
Yeah, do what kpjimmy said; go to a store where Sensation's are sold and ask if you could use a battery to test it out to see if it's bricked. It it's not, you'll need a new battery (try getting one for free from HTC, citing warranty. I did it with my battery cover). If it doesn't work, you're mostly likely bricked, unfortunately. Refer to anarchy's post for more info on that side of things
Same problem here yesterday.. can't charge. But phone heat. I just pull out battery, n put back.keep repeated that. Finally can on. U use custom kernal?

Havn't had the time to really do any custom ROM or the like, so the phone was all original from the factory...

[Q] [i9023] Water damage - USB won't connect to PC.

Hi there,
My Nexus S (i9023) phone recently fell into a water bucket and I immediately pulled it out.
Not much damage was done to it except of one thing: after I put it in a bag of rice like stated on the internet for overnight, and then plugged it in again to the charger, it seems like something was different.
When I plug the phone to the AC power - phone DOES charge, but nothing else happens.
It doesn't turn on screen and informs "charging", and doesn't have the "charge when phone is off" option anymore. Instead it would just turn the phone on.
Also, when connecting the phone to the computer nothing happens, it's just charging the phone! can't mount USB anymore
I took the phone to a lab which handles these cases. They replaced the USB port and cleaned all the corrosion. They said it's fixed now, and indeed the USB port is new.
But then after coming back home it's still the same.
I'm sick of being dependant on other people and would like to fix it myself.
Any clue which part of my phone was fried? Where can I get it?
Thanks!

Are u rooted?
Try a different ROM. Maybe one ur ur backups.
If it still does connect then it has to be the ROM assuming ur computer has the proper drivers still.
Good luck
Vs Nexus S 4G
Thanks!
Thank you!!!
Problem solved after I loaded one of my backups.
Any explanation to that? even when the phone was turned off it couldn't charge it in off mode and now it can.
How come it's a software issue?
Thanks!
I can only guess that ur ROMs kernel had a "fast charge" option. If so this doesn't allow computer connection. How it got switched to that option... who knows .... maybe the sudden power surge.
If not that, then ... strange things happen when a phone get wet.. the sudden power surge could have changed the power output causing CPU adjustments... who knows.
I'm just happy it worked for u.
I'd recalibrate ur battery asap.
Good luck
Vs Nexus S 4G
Hi, the same thing happened to me, only it wasn't a bucket, it was a pool, and changing the ROM didn't work (I've flashed at least three different ROMs since then, kind of hard when the USB port doesn't work but eh, what can you do).
Also, it's on a Gio, not a Nexus S, but the principle should still be the same, yes?

Phone wont power on, heard of a program that might help, but dont know the name.

Like to start off saying hello, great to be here great amounts of information.
I Have me a Huawei U8800-51 (Impulse 4G).
I Just got the one used. Rooted it, and got around to working on it to get Gingerbread on it. It all worked out great.
It worked fine for 3 Days suddenly i decide to reboot it. it shut off but never came back on. Battery was fully charged.
Removing battery for an hour solved nothing. Attempting to go into debug (Vol + & - with power held down) or CW (Vol + With Power held down) resulted in nothing. The phone always when off would turn on display battery charging when connected to power. no this dose not happen.
I still think the phone is drawing power from the battery in this state because the phone would get a little worm like normal.
I talked to someone that ran into a similar issue with a different phone he once had. He Spoke that he had to download a program which was posted about on XDA, which allowed him to power on the phone by forcing the ports open when plugged into USB.
Thing is, he cant remember the name. So I hope for a little help with this. right now im stone broke so i cant afford to buy any mod cables. like JIGs or anything. If a certain cable is needed whats with the cable that makes it different? (If i have too ill rip bits from other old electronics to find a match and attach it to a old spare cable.
I think the problem with the one is related to the changes i made and something must of been buggy.
Even know i got the phone cheap and used. i hate to just ended up with a $120 Paperweight.
Worked all like new when i got it, nothing wrong with it, not even a mark on it.
Feel free to give me a answer even if you have to have Linux to do it. i got both Windows and Linux on my system.
Thanks in advance.

OPO doesn't charge!

Hey guys.
Got a big problem. My OnePlus One 64gb doesn't charge anymore. When I connect the original power cable, the led shines up for a very short time and then disappears. The percentage isn't going up. The icon in the statusbar whereas indicates that it would charge.
Currently I'm on 36%. I've powered off the device and plugged it in to the charger. But it seems that it isn't charging in this state too.
In the official OnePlus forums there are several other guys experiencing the same problem, but no solution was found.
Is there any help for me?
A USB connection to the PC seems to be impossible too.
Please help me guys. I need my phone!
Thanks

Need a little bit more information on your phone. Rom, kernel, any mods etc etc.
Have you tried different combinations of cables and plugs??
I would suggest backup all your important files now, so you won't be panicking when you phone has lost all charge.
Then, try a factory reset and see if they works.

[Completed] LG G2 No power...Constantly Vibrating

Hey everyone 2 weeks ago I was using my lg g2 verizon model running android 5.0.1 lollipop and it felt from my bedside. Note this is not her first time the phone had fallen. I have a tpu case on it and it usually fears very well against occasional drops. That fateful night however the phone fell and when i picked it up it went blank and was switched off. I tried to power it on by pressing the power button but the phone just vibrated continuously on a second by second basis ( literally counting mississippis). I then tried to plug the phone into my wall outlet to force a boot but it just vibrated too.
Later that week i opened it up removed and reattached the battery cable and IT CAME ON!! Two short days after i rebooted the device for a new app but then it didnt power on. The same problem occured. I tried my fix again and after a couple of tries it finally worked. A week later and forgetting my phone problems i restarted ny phone again only to find out that the problem had returned. After trying my quick fix over and over again, nothing seemed to work so i decided to try troubleshooting the device myself. My results have left me baffled.
Ok so before you guys start shouting out solutions, heres what did and found ;
1) Tried a new battery and the phone still vibrated.
2) Unplugged the battery from the motherboard and plugged in my charger and the phone still vibrated. Lead me to believe that its not a battery problem.
3) Removed all un-neccessary components from the phone ( camera, screen, mic, antennas, etc...) the phone still vibrated.
4) Removed the power button module from the phone and it still vibrated when the charger was plugged in.
Note: I disconnected the vibrator behind then motherboard and held the phone to my ear while I plugged it in to my wall outlet. I could hear a faint clicking sound in a cycle.
Im completely lost sorry for the long thread but if anyone can offer some advice please help me i have no money to buy a new phone atm #life
Thank you in advance xD

Hi and thank you for using XDA Assist
Unfortunally for your phone this is indeed an hardware problem and i doubt it may be a software one...
If you didn't "worked" on the device from the software side i think the better way is to take it to an assistance shop or something like that in order to fix your vibration problem.
But for futher assistance i suggest you to ask overe here: Android Q&A, Help & Troubleshooting
Or here:
G2 Q&A, Help & Troubleshooting
Good luck!
