SMT700 Won't Boot correctly - Galaxy Tab S Q&A, Help & Troubleshooting

Hi. I've got a SMT700 that I purchased new and have used for several years with only minor troubles(Having to reconnect the battery occaisonally) and recently I had a new issue come up I've no idea how to fix. My knowledge on this stuff has extremely large holes in it, so I may have missed something obvious. I've been poking around all week trying to figure it out to no avail.
Anyway, the issue: My daughter was using the tablet and it became unresponsive. I popped the back off and fixed the battery cable(It had come out) and after doing so it flat out refused to turn on. Wouldn't boot in recovery or anything else I could think of. So I plugged it in overnight and let it charge just to make sure, since I wasn't sure if it had had much of one when it turned off. Will not turn on. If you push the power button while it's plugged in, the status of the charge(Says 100%) will blank out and then it resets like I just plugged it in. I've found that if I try to boot it in Recovery, it will come up just fine - if I unplug it, it turns off instantly. If I reset it, it turns off and goes back to the charge status screen as if I just plugged it in. It just has the Samsung firmware installed, I believe fully updated(I rarely check it since the tablet is old and it's literally just used for Disney+ for the kid lately) I'm at loss for what could it causing it or what I can do to fix it. Anyone seen this and able to point me in the right direction? Thanks for your time.
Oh. And I have tried plugging it into the computer, but it doesn't even register as plugged in(Can't do recovery or anything) - that didn't really surprise me, it wouldn't charge that way before so I didn't think it would work.

[Q] Help!! a100 Blackscreen

i have a a100 with the latest flexreaper rom installed and im stuck with a pretty serious issue:
a couple of days ago the tab was acting real slow and sluggish and getting bad battery life didnt think nothing of it so i just rebooted a couple times and left it alone . all was good untill the battery hit 10% and i plugged it up using the factory ac adapter. the next day (maybe 6-7 hours later) i went to turn it on and nothing no vibrate no screen flash nothing; other than the power button turning blue as i pressed it and it would stay on for a couple hours but still no other response from the tablet.
im at my wits end on what could be wrong and now i got my wife with her foot on my neck till i get it fixed. can anyone help me?
ive tried to do a hard reset with the reset button tried to boot into recovery /bootloader no dice
(also my home button flashed a couple time i pressed the power button) dont know if its relevant but wanna get as much info out as possible
wondering if anyone can help me...

It may take awhile for someone to see this and form something to try, random bricking for no reason is rare, its almost always some error by the user. However have you attempted adb connection to it? Leave it powered off, connect to the PC you used to unlock the boot loader then power on. Does the PC make the USB connect sound? Does the Acer vibrate? Did the home key blink again?
It really sounds like your boot partition is wrecked which wouldn't normally happen outside of flashing. If boot loader is trash then it won't know what to do and just sit there. No recovery or anything else.

it made something like the connect sound but instead of the regular duh doom sound it did a dadadoom (kinda hard to describe the sound) but it was faster than ive ever heard the connect sound before which is weird. the tab didnt vibrate and it seems the home button blinks when the tab is dead and needs recharged

Yeah I know that sound it means USB connected but error for some reason. Its been shown if this thing dies all the way down it wont read the battery correctly and probably needs to be sent in. Before that I personally would unplug it open it up and remove the battery for awhile, maybe an hour then put it back and plug it in. But thats me, not the advice I'm giving. If you have warantee on it use that.
The batteries on a lot of devices and laptops etc have something of a fail safe, if the voltage drops below a certain point it trips to prevent cell damage, however it renders the battery useless.
I haven't searched out much past that if a reset is possible by us, but it seems the pack is trash after or needs sent in.
Since this is a sealed unit you void warranty opening it (well unlocking the boot loader did too) so you can't send it in for repairs without paying for it.
I hope someone can jump in and help figure this out, and prove me wrong.

Weird, This exact same thing happened to me. Used it in the morning and now after work it won't turn on. I had already tried disconnecting the battery, but hadn't thought to leave it disconnected for an hour. My tablet has been running the leaked ICS since it came out and The last factory reset it had was about a month ago. It was working fine up until this. The power button seems to be responding correctly, the issue is that after the LEDs light up, there is no vibration or display. I hope someone can help us with this issue.
EDIT:
It won't connect in ADB mode. It will only appear on my computer as an APX device and since there is no vibration I am unable to boot into fastboot. Any help or suggestions? All the threads I have found have involved booting into fastboot.
i am also having this problem. i set ti backup last night to save to box i turned it on this morning it.worked set it on the charger came back to a frozen screen. I turned it off now just a black screen it turns on or the home button dose but nothing comes up on the screen

I have been using ICS the leaked one, and last night I was goint to check my email and it did not turn on, I though the battery died. I plugged to the charger and this morning I tried to turning it on but it failed. I did the reset pin but nothing. I connected to the computer and it was recognized as a APX device and installed a driver ACER Picasso USB recover but i cant access anything. I am a nob. Thanks
A100 blackscreen
i am also having this problem. last night. just a black screen it turns on or the home button dose but nothing comes up on the screen. :crying: Help!!!!!!
Has anyone tried holding the power button for a while? Laptops do this too, if someone felt ventures, try taking the battery out and hold the power button. No promises, might work.

Having the exactly same issue, here...
I also tried to hit the hardware reset button and it does not help.
If the screen is blank while powered on its in failsafe mode, in other words is bricked, has to go to Acer.

This just happened to me a few weeks ago as well. If you are still under warranty send it in to Acer, thats what I did. I just got an email saying they had fixed it and were sending it back for free!!
At the time I was on the 9/02 JB build. I wonder if this issue is caused by faulty hardware or if it is an issue that was made by rooting and unlocking it? I don't know enough about this stuff to answer that though, but it does make me think whether I should root/unlock it when I get it back or leave it stock.
Also thanks Pio_masaki for helping me a few weeks back wasn't sure if I was even going to send it in until you said they most likely won't be able to tell.
I highly doubt they even CARE when sending these in. They will void for physical damage most likely.

Ohmygod,
Same here, but it's 3 years ago. Sorry for digging the topic. Still no hope? I still keep the tablet and have just buy another refurbished mainboard to replace but still no vibrate and blacksreen still there.

[Q] HTC One X won't turn on

I know there are already a LOT of topics concerning this - I have read through them all frantically, trying to find a solution before turning to asking myself.
So, here's exactly what happened, and what I've tried.
My phone was just fine, running perfectly, nice battery life. I had been running CarbonROM for about 2 months, without any issues, didn't change anything recent to this problem occurring. So one night I was at a party, and didn't have an available charger, so my phone ran out of power completely. The next morning when I came home, I set it to charge, the LED lit up, as far as I remember at least. In the evening I turned it on, and I got to the SIM pin-code unlock screen. I entered the PIN, and my phone turned off. No crash screen or anything, it just went straight out. I figured that maybe it hadn't charged properly, so I let it charge for a few more hours, and then tried again - same thing happened. I instantly tried to turn it on again, but this time nothing happened at all. I held the power button down for at least 1 minute, to no avail. When I put in the charging cable, the LED doesn't light up.
So, as I said, I have been reading around on this forum and other places, trying to find a solution. Some people said holding down the power button and volume up and down at the same time for 2 minutes would fix it, it didn't. I have tried several times. Most recently someone said I should connect my phone to my PC with the USB cable, and then hold down the power button and volume down. This time, something did happen. But not on my phone's end. I have done this 2 times, with the same result. At exactly 7 seconds, my computer turns off, as if I had "choked" it by holding down the power button on the PC. This seems really odd to me, since the phone can't even turn on, so I don't see how there can be any connectivity.
I hope someone here has a solution, knows why it happened, or can at least guide me in replacing any part if needs be. I hope not, though.
Bump
Should I just send it in for a repair? I have an idea that doing so will be very expensive...

LG G3 D855 - Rebooting when not charging

I have an odd problem with my phone.
All of a sudden the phone would automatically shut down and reboot when it's not plugged into a charger.
IF FROM BEING POWERED OFF
It shows the LG logo, stays there then shuts down and reboots to do the same thing over and over again.
IF POWERED ON THEN CHARGER REMOVED
it will stay on for a random amount of time, but not more than a minute. it will function properly for awhile then shut down, reboot and do the same thing as above.
IF WHILE BEING CHARGED
it works normally. i can do anything on the phone like theres no problem.
even stranger:
i did a factory reset, and it did so without a problem. when it finally rebooted and it shows the first few options (language and accessibility) when setting up the phone, it stays on for a long time - as soon as i touch the screen though it powers off and reboots again. i was able to set things up again while the phone was plugged in.
now i cant use it without the phone being charged.
*additional note:
it may be related but this started the other day when i went out for my daily jogging routine. I usually keep it in my front shorts pocket while i listen to music. about 40 minutes in and i realized my music stopped - when i checked the phone it rebooted by itself. maybe it got wet by a bit? when i took it out of my pocket it was pretty dry though - it wasnt like it was dunked in a glass of water or anything.
I checked online and some have reported having the same problem and changing batteries worked. i just dont want to waste money on something that might not even fix the phone.
You need a new battery i believe, had a problem like that with a family members G3 - battery replaced, fixed - otherwise it would turn off randomly/when doing anything that is considered intensive (touching the screen counts)

just saw your reply now, thanks for taking the time to reply.
i did a lot of research when the problem arose, tried factory resetting, switching roms (to stock and custom) and nothing worked - asked around and it seems it WAS the battery all along. now it works perfectly and it lasts much longer than before.

Hey, I had exactly the same problem. Did everything but no use. Then i changed the battery and voila no restarts or power shut down since 4 days.

Phone was stuck on bootloop, now won't turn on or charge

Yesterday my phone got stuck in a bootloop (wouldn't go beyond the htc logo screen, recovery was still accessible) after turning itself off (from being too hot I think?). I turned it off via recovery as there was no other way and I wanted to look into the problem now, but the phone won't even turn on anymore. It doesn't seem to charge either (at least the LED doesn't light up).
It's running Android 4.2.2 I think (the latest officially provided) and is rooted. I did not change anything system related recently. The last "noteworthy" things I did were updating a game and "playing" it for maybe 30 minutes (I use quotation marks because I think I left the game running but stepped away from the phone for like 5-10 minutes, but I can't say for sure; it was turned off when I came back), until itself shut down.
The only suggestions I could find for phones that would not turn on or charge were trying different cables/power sockets and removing the battery. Tried 2 different cables on 2 different sockets and my PC; removing the battery it not really possible with this phone...
Any way to fix this?

Recover photos and videos from broken Nexus 5X

Hello friends,
I’m new to this forum (or, any forum, really) and in desperate need of help.
Hopefully I'm posting this correctly.
In 2017 (I think) my mom bought a Nexus 5X phone. All was well, until suddenly it broke in 2019 and she had to get a replacement. There were a lot of pictures and videos on there (no SD card was used) that we do not have a back up of. (I know, that’s a big mistake...)
What happened: it just suddenly turned off and didn’t turn on anymore. When I tried to figure out what was happening, the only response the phone gave when I plugged it into my PC was a blinking red led underneath the screen. I figured the issue must’ve been with the battery. After a while, it didn't even do that anymore - not a single response was given.
It took me until 2020 to try to replace the battery with a new one. I think I managed to replace it successfully, carefully using two YouTube tutorials. When I held the original battery in my hand, I could bend it easily, so I expected that would solve the issue. But the phone didn’t give a single response to my efforts.
I also tried heating the phone as instructed in this video (with subs):
Again, without any success.
Since I didn’t want to give up on the stuff that is on that phone (precious memories of my cat who passed away at the end of 2020, for example), I randomly tried tinkering with it again a few days ago.
When I plugged it into my computer again, suddenly the red led started blinking again... And a few moments later, the Android logo lit up. Then the screen turned black again.
I noticed that when the phone was plugged in, my PC made this noise that recognizes something is in fact plugged in. However, it didn’t recognize the device.
After trying multiple times to hold down a few buttons, I first managed to get a screen that said “Firmware update”. It disappeared after a while, and showed a Google logo. I don’t remember exactly, but I think the time after that when I pushed the on/off button, the phone actually turned on and I could use it.
I could see all pictures were still on there. I immediately tried to copy them onto my pc but before I could do that, the phone shut off again and connection with my PC was lost. Battery was charged to about 70%.
I managed to reboot it a few times, but the time it stayed on became shorter and shorter. I wanted to try the debugging method and recover data that way, but it simply didn’t give me the time to do so.
A few days later, I still get the red blinking light and sometimes the android screen or a battery loading screen. Other than that, I can’t turn it on or get into safety mode, or anything like that. It *does* still connect to my PC, but doesn’t recognize the device.
TLDR; Nexus 5X shows blinking red light, doesn’t turn on and if it does, it almost immediately turns off again even after replacing its battery. All I really want is a way to recover the photos and videos that are on the device.
If anyone has any leads or tips that could be of help, they are most welcome.
