I got a Note 2 from a guy on Craigslist that apparently had died. Wouldn't boot, no lights, but battery did warm up after staying on the charger for a while, so it seemed to be charging. Got another note 2 with a busted screen, but which does boot. Screen is completely shattered with no backlight or image on the screen, but you can hear it fully boot. When I swapped the board from the second phone to the dead one, nothing happens still. No boot. No blue light. Nothing at all. I tried the board I pulled out of the first phone in the shattered phone and it appears to boot. Swap the board that came out of it back and it boots, but nothing happens with either board when I put them into the first phone. I've also swapped the usb boards and they both work in the phone with the shattered screen. I'm stumped! The first phone I got is super clean, and doesn't appear to have any water damage to phone or battery, and my shattered note 2 boots with both batteries. I thought the issue was the well known sudden death issue, but it seems I have a different problem. Any suggestions?
edit: Well I got the first phone to boot with the original mainboard, but it will only boot if the connector on the top right (looking at the rear of phone) is disconnected. When I connect it it won't do squat. I'm assuming this is the video connector, but not sure.

Hello,
Saturday I went out, my HD2 only had like 5% battery life. I used it till it went black. The day after I wanted to recharge my phone but when I plug the microusb in to the wall charger, no led lights come up. When I press the power nothing happens. Stays black, it's like a dead stone now. I did not flash the phone for the past 2 months, it's running android already a long time now.
This morning when I pull the battery out and put it back in and push the power button then a VERY short vibration comes out of the phone but then nothing anymore the screen and leds stay dark. If I try it a second time nothing happens. So I think the battery is 99.9% empty and I can't charge it anymore through the microUSB. The only thing I can think of what happened is saterday I took a bath and my phone was lying on the edge of the bath, it did not fell in the bath offcourse. But there was alot of humidity in the bathroom because of no ventilation and warm water. The phone was working perfectly after the bath and stayed working untill the battery went to 0% when I was going out. Is my microUSB port water damaged? The stickers inside the phone are still white. (luckily). Anyone has an idea how to fix it or what the problem could be?
Remove the battery.
Connect to the power supply.
After a couple of minutes, plug in the battery (while the phone is still connected to the mains supply).
Ok I tried it.
Took battery out. Connected to usb power cable.
Waited +- 5 minutes. Inserted battery -> nothing happens.
Won't turn on, no led lights.
BUT I noticed a strange thing.
If NOT connected to power cable : Take battery out, reinsert. Power on, -> some milliseconds of vibration.
If connected to power cable : Take battery out, reinsert. Power on, -> nothing, no vibration.
So if it is connected to power cable phone acts completely dead when I reinsert battery and push power button. But if it's not connected then when reinserting the battery and I push the power button then a very short vibration is felt.
Weird ... is there something shortcircuiting the phone when connected to powercable??
Ok,
I found someone on my work who has an HD2 like me. So I tried to put a 70% charged battery in my HD2. Guess what ... same result. A little vibration and it stops .
So now I know it is not the battery. It's the phone itself. I've put it now in a bowl of rice and hope next morning it will be magically revived. Maybe when I took a bath saturday there formed some micro water bubbles inside the phone and it still isn't gone by now? I am out of ideas. If this rice thing doesn't work I'll send it to HTC repair centre. They won't notice my hspl because they can't even turn on the phone with a charged battery. I'll guess they'll swap the mobo .. again. My previous repair was because my HD2 was in a constant Carkit mode (also a hardware issue). Sigh
Can you get into Bootloader Mode (Press and hold the Volume Down button, then tap the Power button)?
Nope, it acts like dead meat, even with a charged battery I could try from my friend his hd2. My battery worked in his phone. So it is my phone who is broken.
Think some hardware is busted ... Maybe some circuit is broken ? I just don't know . Now they must repair it for the second time. The first time I got the "phone is always in carkit modus" issue which is also hardware related. I hope they will not make a problem to give me yet another motherboard and yet another IMEI . That will be my 3rd IMEI on this phone then.
Hope they pick it up tomorrow .
K Update to this post.
I've received my HD2 back from HTC repair with a new motherboard / IMEI.
All is working now again .
I am afraid it can happen again . This is my 3th IMEI / mobo now on this phone after owning it a year and 2 months.
They now also didn't put a new "VOID" sticker on the screw
Also no "water detector" anymore.
It seems like they are saying to me, now if the phone breaks again, you have no warranty anymore. It's not my fault the mobo suddenly dies . I doubt it they just "forgot" to put new void stickers on.
Never take cell phone in the bathroom.. especially if its a touchscreen.. the steam from hot water gets accumulated inside the phone and ruins it. My friend damaged his 2 handsets already.. now he doesnt take it in the bathroom anymore

There are water dector labels inside the phone and if they forgot the VOID label then that is their problem. You have twice returned the phone and by replacing the motherboard they have admitted that the problem is theirs. So they already have a history of faulty phones from you and since it has been repaired by them, then they would need to show a record of placing a viod label back on the phone.

Well I also think that was the cause the phone died later that evening.
I think the phone went dead sometime that night because of the water inside the phone. Luckily the water detection labels where still white .
I never will let it inside the bathroom again .
As for the void sticker problem, I will contact them to ask why they didn't put on new stickers. If they don't respond I saw you can buy such stickers on ebay .
Hi everyone,
I purchased a used AT&T Note 1 ( i717 ) with some cosmetic defects. Ordered new parts from various vendors. Everything on the phone worked okay prior to repairs. I replaced the front bezel and put in a new screen with glass. The screen and glass came as one unit. It was almost $200. After the minor phone surgery, which took about two hours, the phone power on. The Samsung logo shows for about a second, the the screen goes black. Phone rings when I call it. All the buttons work, but nothing shows on the screen. I can put it into download mode, and the screen displays the download mode on it. When I try to go into recovery mode, the screen is blank. Also, with the phone powered off, when I plug in a charger, all I get is an image of an empty battery with a circle in it. I ordered a new battery, and the same thing happens. Again, screen only stays on in download mode, and battery won't charge when the phone is off. Please help. I'd hate to think all the money and time spent was for nothing. Thanks.

More courage than I to do the work. All I know is you are not the first to have this problem. If you ran a search on screen replacement, you would most likely find this out and the solution.
Good luck.

Ribbon Cables?

Go back and check the ribbon cables and the pin connectors. These are always troublesome and very easy to damage, the video cable in particular. Another thing to check is that the on/off button is not obstructed in some way by the new bezel.
Lastly, do you have an external charger for your battery? If the new battery is factory fresh you may need to charge it prior to putting it in the device just to check that the USB/charging port is working.
Good luck.

Thanks for your replay. Checked the cables and the switch a few times, and it didn't correct the issue. I ordered a battery charger for Samsung batteries. Should be here Friday. I honestly believe it's a battery stats issue. At least that's the impression I get reading other posts, but I can't get into the recovery mode to reset unless there's a way to ADB without a working screen. Thanks again.
Phew... The external battery charger did the trick. I removed the battery from the phone, and fully charged it using a Hyperion Dual charger. Re-inserted the battery, and turned the phone on. At first, phone turned on with a black screen, but once it booted up, I swipe unlocked the phone. The screen flickered for a few seconds, and voila... phone is again fully functional. Thanks everyone for very thorough, and insightful posts. Xda-developers.com Rocks! :laugh:
Hello,
I have been struggling to find a solution for months now. My problem with the LG G5 started when it complained about the bottom cover. Every now and then it would show a screen that the bottom cover is not plugged in correctly. By unplugging and plugging it a few times the screen would go. Eventually, although I am not sure if it is related, the phone stopped turning on. When the USB cable is plugged in I get a screen showing the battery is at 0% and the red LED flashes as well.
I have tried the following:
1) Replaced the battery
2) Replaced the bottom cover
3) Inspected the logic board and cleaned it with a PCB cleaner.
Note that the phone had no contact with water.
I would really appreciate it if someone knows what could be the fault.
Many thanks
Dropped my Poco F1 in the sink. I didn't turn it off immediately as it worked for ~30 minutes (this is stupid I know.) Eventually the screen stopped responding and turned off. I took it to a phone repair place who pulled the back off and dried it out mostly, but as they were unfamiliar with the phone didn't want to proceed further. It's since been 2 days since it got wet so i tried plugging it in. The charge light started flashing which was the first sign of life i'd seen from the phone. I tried turning it on, the screen came on with a faint black very briefly with a short vibration also. The phone promptly shut off again and now not even the charge light is showing anymore.
What would be the best thing to do from here? I thought about getting a replacement screen however it takes at least 2 weeks to ship to Australia from any of the vendors I've found online. Would the replacement screen be worth it, or is the issue something else?

It's completely damaged.
Screen got shorted out from the water and motherboard is damaged based off of the nonresponsiveness / partially damaged response of the Android OS.
It progressively got worse because the water caused corossion of the metal components.
Sad to say it's completely unsalvageable except maybe the camera.

Pocophone has no given IP Water Resistance Rating since Xiaomi launched the Pocophone, but only certified Splashproof rating. See the video on JerryRigEverything wherein he did a teardown video and saw all components of the Pocophone and proven no water protection in Type-c port, headphone jack, speakers, etc.
In your case, 30 minutes underwater? It is dead. You can salvage it but not everything.

It wasn't underwater for 30 minutes. It was only underwater for a few seconds, but it was working for about 30 minutes after it got wet, and then shut down completely. I have taken it to another repair tech who got it working again, it is responsive/vibrating however the screen is still dead. Any recommendations for a replacement screen?
Place it in a sealed bag full of rice for at least 24 hours.

How deep was it? Where did it fell from?
What was the outcome ? Have exact the same accident

Hello,
could you mabye say if the display replacement worked for your pocophone? I had exact the same accident (phone fell in 2-3 centimeter salt water, worked for 30 minutes, after then screen went off, charging light is working).
Now I know what sould have to do first: turn off the phone immediately. Second mistake, I did not save the holiday photos on external storage, just on internal.
All data maybe is lost...
BR,
Alessandro
I dropped my phone in the pool and it died. Completely dead. I also made the mistake of trying to switch it on. Two repair places said it was finished (not quite sure what these guys do, but it's not repair phones)
I dried it in rice and salt for a couple of days and it was still dead. So I took it apart, washed the motherboard in alcohol and it sort of came back to life, but wouldn't hold a charge or switch on, but was memory visible via the USB on the computer, leading me to believe the motherboard was "alive".
I took it apart again, washed the main board, charging port, dried and reassembled. It kept switching off when the screen was connected, so I disconnected the screen and charged the battery: Everything okay, can connect via usb, charge stable, LEDs doing their normal thing. I assumed the short was somewhere in the screen assembly, so changed this., I can now even boot in "recovery mode" and see the memory rather than the Hisuite thing. It even connected to to the car via bluetooth. It *even* started playing music which I suspect was a 911/112 waiting ring I must have dialled by accident since it has no SIM.
So the phone is "alive" the touch I'm guessing work, the display is brand new, light up but displays nothing.
I'm running out of ideas of how to wake up the display though and am thinking it might be a problem with the graphics card, although I don't know how to test this.
My priorities are:
Return the phone to it's state before being dropped (i.e. solve the issue with the screen)
Access data (n.b. I haven't got Hisuite installed or activated and it doesn't simply give me access to DCMI and contact which is what I care about)
Hard reset or similar to return the phone to function with data loss.
Change the motherboard (I don't really want to do this).
