Hd7 randomly wont wake up - HD7 General

I have an hd7 tmous, and this problem has persisted on the original rom, and the official nodo, both locked and unlocked. Phone will work fine, run it all day, then while I'm at work, phone in my back pocket, it won't wake up with any button, and I have to pull the battery. Only when its in my back pocket. Sometimes takes 5 minutes, sometimes a few hours. Front pocket takes more time. Any ideas? I thought about trying another radio. I have search xda and the net and can't find a solution. Got it used and have no warranty. Any help is greatly appreciated. Thanks.
Also, on my days off, and the phone never goes in my pocket, no freezing. How odd. Sometimes its really warm, almost hot.....

I've had a similar problem but only when its been on charge a few hours. the lil green battery light stays lit but the phone wont respond unless I do a battery pull

Hmmm. Now that you mention it, every time it has done it, it was about 80+ % charged. Never done it on half charge. The green led that you mentioned doesn't behave as you said, but you gave me an idea- battery maybe? Gets hot, only does it when mostly charged, it makes sense.

I recreated the problem. Putting a fair amount of pressure on the bottom of the phone, just below the battery cover causes the screen to dim, keeps dimming, then the phone is off. Seems like a short. Gonna take it apart when I get home. Fun times, lmao.

SOLVED
I was right, it was a short. After a little process of elimination, I narrowed it down to the protector shield/heat sink that the SIM card/sd card cluster rest on. I pushed on the SIM card bracket, and it dies. I unplugged the cluster, left it on, same result. Removed the cluster and the shield it is stuck to (by adhesive), and it didn't die. Increased the pressure until my screen made funny colors, still didn't die. There is a heat sink pad and some amber "tape" that are on the underside of the shield, centralized around the CPU. The area I pressed on was on the opposite side of the cluster though. And, oddly, there was no protective amber "tape" on that area. I cut a piece of clear packing tape, made it just the right size to cover the area, and not overlap the amber side. I put the shield back together and the problem is gone. Turns out that when my phone was in my back pocket and I bent down for something, it would put pressure on the bottom of my phone and short it out. Considering the area of the short, I feel very lucky that my phone is still kicking. I am posting this to help anyone who might have a similar problem. I hope this helps. Easy to take apart, unlike the hd2
Thanks, xda, for without you and your awesome gathering of people, i would be lost...... And bored.

[Q] Drunk G1 turns itself off

Hi fellas, long time no see!
So, first of all, yes, I've used the search, but what I've found is threads about wet phones, mine I believe is already dry.
Situation: I'm in the club, glass of absolut and redbull in my hand, phone in my jeans pocket, extra glass of absolut w/redbull on the bar next to me. Fat drunk aproaches the bar and tips my glass with his elbow, all my drink spilled over my clothes. After a brief discussion I realized the guy was too drunk and was a worthless douche so I let it go. I reach for my phone and realize my pocket is soaked wet, when I take it out, phone is out, red light dim. So I turn it off, take it apart and forget about it til the next day. Next day, it began to turn on, but shut itslef off after a few secs, so I take it apart again (that is back cover, battery, SIM and sd, I dont have the screwdrivers to go further), cleaned what I could with alcohol, let it vent in front of a fan for a few hours, then in a bowl of rice for 2 days, no good.
So I got an extra phone and let it sit for more than a month. The other day I decided to give it another try and voila! it worked, had to be dry by now! used it for a day, left it charging, when I came back, it was off again, unresponsive. I have an extra battery, so I got one of those universal battery chargers, because I though the problem could be the phone not charging the battery. It was (even when the light turns on red and it says charging and all). So, first weird thing, light turns on red, screen says charging, but USB wont wont actually charge the battery if it is somewhere below.. 70% maybe, it does charge if it is lets say about 80% or above.
I used it like this for a week or so, and now, when I turn it on, after the bootscreen and the initial loop, the phone now powers itself off (with the text "turning off" -or whatever it says- and vibrating and all), even with the battery full. Tried with both batteries full, plugged in the usb (the light is green when full, and will even charge), erased battery stats (recovery works fine) but the damn thing wont load android properly!
Any ideas what might be causing this? it should be dry by now (its been like 2 months already and I let it vent and used the rice method), it doesnt smell funny (you know, like burnt, like when sth short circuits).
btw, also tried flashing the ROM again (i always have a couple in the sd just in case) and didn't work neither, does exactly the same.
i know it is a bit long to read but i wanted to give you the most insight i could. i know that it works! it did a couple days ago, but something got screwed with the startup and i dont know what it is!
i see that u tried flashing the ROM again, but just to be sure u did do a super wipe correct?
this is very strange though, and yeah it should be dried by now.
Thanks for the reply, and yes, I did! I'm sure that is not the problem :/

phone randomly shuts down

i had replaced the digitizer on my vivid recently and now it would shut down randomly and even when i turn it on it would stay on for 10 second to 2 minutes and would shut down and this cycle continues until the phone "decides" to stay on. This only happens when the phone is not charging, when the phone is charging it never shuts down. Sometimes the percentage of the battery will jump for example: it could be at 60% then it shut down and when i turn it back on it would be at like 40% and it would shut down and when i turn it on again it would jump to like 56%.
Thanks in advance for any help
edit: when i had to take the digitizer from the screen i destroyed the tape sticking them together, im just sticking them together now with normal tape i had order adhesive strip to fix that. I also forgot to take the plastic off from the digitizer side that goes infront of the lcd screen. i dont think any apps is causing this.. i use to think battery is problem but now think otherwise..it doesnt shut down when my sim isn't inside.. only testing this now not 100% sure
edit:everything seem to working except for flash photography without the sim card. also when making phone call the screen keep going dark maybe a sensor is covered

[Q] Another Water Damage Thread

Howdy,
Long version:
I left my galaxy note on the counter in my kitchen which is apparently not quite level. Overnight water pooled under it(never submerged, even partially). I did not notice until my alarm went off the following morning. As of this time it was still functioning properly. I moved it, wiped off the water. Took the protective case off and wiped the water off it was well, hooked it up to the charger and went back to sleep. 15 minutes later the vibration function went nuts while it popped up complaints about low battery. I say the vibration went nuts, because it wasn't the sustained vibration like you normally get it. It would cycle on and off about every half a second. I panicked, turned off the device and removed the battery where I noticed that the battery was wet, and under the battery as well.
So I wipe it off, put in a bag of rice and go back to sleep. Approximately 15(yes, way too soon) hours later I pull it out, put the battery in and turn it on. Works fine. few hours later I hook it up the charger and it immediately complains about the battery temperature.
Short version:
Phone at in a pool of water for 5+ hours, never fully submerged. Basically if you poured water on a level surface and sat your phone in it, thats what happened.. Anyways Water worked its way inside the phone(based on disasemble that occured later), and started vibrating randomly. took out batteyr and left in rice for 15 hours. Put it back together attempted to charge, phone complains battery is too hot immedately.
Observations:
I take out the battery and disasemble the device down to the point where the circuit board is separate from the display.
The far right ( +) connector that touches the battery appears to be slightly corrodeded. I rub it with a cotton swab to clean it. From watermarks it doesn't look like anything else got wet and by now its completely dry. I don't see any 'red' spots or stickers, but I'm unfamiliar with the water damage indicators, and the information i found from searches was innacurate(no white dot on top of battery, no red marks anywhere on it)
Panic
I put it back together try again, same deal. The phone doesn't seem to have a way to view the battery temperature reading(*#0*#), so I downloaded an app called 'Doms diagnostic tool' which indicates that the battery temperature is pegged at 80 degrees C and it does not fluctuate. I don't know if this app is actually reading anything though.
Can someone who has a working phone try this out? App is free.
Is it worth putting it back in rice even though its dry even on thorough dissemble?
Any idea how to get legit data from the sensor to verify if its shorted out etc?
Would a replacement battery with out the sensor resolve this issue?
Anyone have pictures of where water damage indicators are?
I searched thoroughly and found no answers besides taking it to a service center. Since I'm in America, and this is an international phone, I don't believe the manufacturer will honor the warranty even if the phone shows negative for water damage. My service is ATT, but I bought the phone at expansys( i think).
best at this point is to check your insurance, if its covered. In some countries I read this is covered as it was accidental.
I would recommend goong to samsung and let them check it, with the true story ofc. Now if they find whats wrong, they might be lenient, or not. Anyhow then you know whats broke, and you can decide to fix it for yourself or have it fixed. At this point it sounds like corrosion on one of the boards, or shorts somewhere.

top part of phone get hot after screen replacement

Hello
My screen cracked so I ordered a new on ebay. However after I have put the phone back in its shell the top part gets pretty hot. I opened it and started it without the aluminum shell to test and there were no heat? Anyone know what it might be?
Thanks In advance!
That isn't likely to be the screen. My phone gets warm too. About 4 days ago out of nowhere I noticed the upper part of the screen feeling warm, it turns out my phone had stopped sleeping properly and Google services had resumed chomping on my battery when the screen was off.
Tho when i don't keep it in the aluminium case it's not warm at all, turned on and I have logged on my simcard/wifi. I have left it on outside of the case for 1 hour and it don't get warm at all. However in the case it gets super hot as soon as it boots and then after 15-25m it turns off probably because it's too hot
Happened the same last night with me.
Put a download and slept, and in the morning it was all drained of battery and it showed that it shut down after minutes after I slept with 90%battery.
It was weird. Had to keep pressing power button for 40 sec approx for the phone to turn on.
It's working fine now though
did anyone of you even read my post? I said after a screenreplacement. It didn't just happened randomly. however i fixed it. I removed the camera and the earspeaker and reinstalled them used some alcohol on the contact points on the case and the earspeaker and it seemed to fix it if anyone has this problem later down the road
Hi jullleee, I have the same problem as u after I replaced the screen. The phone getting too hot on the top (one plus 3). On charge it becomes more hot and faster on very high temperature than without charging. Also the battery dont charge . Why did u reconnect the ear speaker and the camera ? Thank you in advance

For anyone coming across this thread I just had the same problem when replacing my Oneplus 3 screen. It seemed to work, and I plugged it in, but it said "battery too low charge for a while", then I got the 0% and seemed to charge and then restart, and then be back at 0% and be stuck in this boot / charging loop. My battery had died hard when my screen died so I thought maybe it just needed to charge for a while, but the top half of the phone got very hot.
So I took it apart again and it turns out the issue for me was with the top ribbon cables that cross the battery. Where they connect to the main board was very tight and it was difficult to get both of them in place properly. Usually they kind of overlapped and one stuck up slightly. It was fixing their placement before bolting down their cover that fixed this issue for me.
Edit: Never mind. Still searching for my issue. Taking the back case off will let it work normally but whenever i snap it on it goes back into this charging loop, I still suspect it's an issue with these two cables and the case is putting pressure in the wrong spot or something but I'm not really sure yet.
I had the same problem, the issue was the fact that i plugged the ribbon cable the other way around.

Xperia XZ2 data recovery after liquid damage

Hi folks,
I have been sitting my friend's phone around for a while.
I somehow made it to unseal the phone, I guess by using an air pressure gun.
My approach was to open it up, clean it out and try to restart it.
Mostly with one approach, making a backup of the pictures.
Sadly, I was not patient enough and partly destroyed the screen.
But after is resembled most parts lossy, I was able to restart the phone.
As the screen was too hard damaged, and it took a while till I got a new one, I took the phone aside.
New screen has arrived after a while but shockingly the screen doesn't turn at all even with the old screen.
As the battery was deeply discharged, it charged it a little janky and messed up the port.
But still not working.
So my last ideas was to tried starting it without the battery, which didn't work.
So here is my question, will it start without the battery in at all or the other way around, could a broken battery terminal be now the main cause for not getting the phone started.
The alarm is still working as well as the vibration and the indicator LED which stays more or less only red.
It needs the battery to boot up. Without the battery the phone likely won't have enough current to boot.
You use heat, anhydrous isopropyl alcohol, plastic picks to get most of these phones rear covers off. Never compressed air.
I would guess that it is not the current, more the basic system how the battery management is realized.
No the compressed air wasn't the reason, it was more the reason for the water leakage.
As the rubber gasket got misaligned with using it to clean up the usb c port.
The display got cracked because I assumed the display would be more narrow like I was used to with amoled ones.
So my spatula dive in between the LCD and the backlight the rest was made by my manual force.
I think I will order a spare battery and will retry it..
Make sure everything is completely dry. Leave battery disconnected until dry.
Do not expose LCD displays to any solvents including isopropyl alcohol as they will poison it.
Things happen... the second time is always easier.
The battery is a cheap fix if it works.
