Hey guys,
I believe this is the correct section for this so here we go:
- The phone worked pretty well for quite a long time until it failed.
- It was never rooted and nothing was done on the OS or firmware besides the official updates
- Currently the phone can't start at all. Then you hold the power button it goes into a startup loop where it shows the initial logo, vibrates and then the screen turns black and repeats all of this until either the battery dies or you hold all three buttons.
- The phone charges its battery without any problems when it's off and simply plugged in the wall outlet.
- I can't boot into the recovery (vol down + power) as it goes in the same power-on loop. Same happens with any button combination.
- All of this happens regardless if the phone is plugged in the charger or not.
My questions are:
- Is there any point in opening the phone, getting the battery out for a hard reset and memory wipe?
- Can anything be done through a computer (plugging the phone and somehow tweaking in the firmware of the phone)?
- Can this be a hardware issue and if yes - what specifically?
I'd appreciate any and all suggestions and comments. If you need photos or any additional information I'd be more than happy to provide it.
Cheers!
PS: This is not my phone so I'm not entirely sure about how it was used (drops, water damage, etc.) but it as far as I'm told it hasn't suffered any damage and it does not have any traces of it (it's my mom's old phone).

Hello
i need help
yesterday, my htc one x+ went out of battery
then, it does not charge any more
i left it all the night plugged, but still cant startup
any idea ?
thanks
its a Stock Phone or customized?
Not even bootloader?
So it's completely dead? Does it boot to the bootloader by holding down volum- and power button?
Are you using a Custom Recovery there are problems with it when the battery gets down to zero. It's happened to me a few times, and I panicked the first time.
Plug it into the wall, hold down volume down, and then power. After 15 - 30 seconds, this should get you into the HTC Menu, I then chose Recovery, and from Recovery launch into System.
-- started up --
Thanks all of you for your help!
sorry for tardive response
it is a standart ROM (no operator) and rooted
here is how finaly :
- must plug it on the wall, not to a PC(dont know why)
- try to switch on with power + volum-down buttons
- after several tries , i get a fastboot menu
- tried all the lines ont the menu : but it never boot, never charge
- finaly, deseperated, i choose "shutdown" line in the fastboot menu
then it restarted correctly with htc animation - ouf - dont understand...
i will never let it go out of battery again
thanks again

It is important to know that the wall charger adapter has a greater current output than just the USB cable in a computer. The wall charger will always be faster (assuming it is relatively modern and has a sufficient amperage) in charging your phone. It may be better to use the one provided by the phone, but generally any wall adapter should suffice in a pinch.
I believe that since the USB is so weak, you either did not wait long enough to let it sufficiently charge, or it simply did not keep up. I've had phones plugged into the computer on charge mode and still have it lose power.
Also, if your computer was turned off, then it wouldn't have been pushing any charge to your phone anyway.
I have a KIW-L24 that has been stuck in a bootloop ever since it was dropped into water. The phone was put into rice for 24 hours but no luck. This particular phone is basically stock - no root, no custom roms, etc.
Current state:
When it was first charging, it appeared to be in a bootloop - showed the low battery icon, then black screen, slow battery icon, etc..
Once it had enough power to attempt a boot it shows the first "honor" boot screen, then goes into the bootloop
I've attempting flashing to default firmware - hold power + vol up + vol down - no luck, still continues to the bootloop
I've also attempted getting into fastboot - hold power + vol down - I can get the initial fastboot screen for a second or two before it reboots
Anyone have other ideas before I call this one dead and get a new phone?
Thanks
Seems more of a hardware issue now than software. Visit Service centre if possible. As you tried other stuff already

Please don't try to turn it on for now. Bring it to service center so that they can clean the insides and remove possibly rusts.
Thanks everyone. It doesn't look like there is a service center anywhere near me.

Keep phone off for couple of days and then restart. Who knows it makes a difference

take apart the phone, remove the back cover, then let both pieces sit in a bag of rice for about 3-4 days, same thing happened with my old phone and that did the trick.
My S9+ was acting quite weird this morning. Some apps continuously crashed or wouldn't start.
So i rebooted my phone (just from the normal power button menu) and then it went completely black.
It doesn't charge (or at least, it doesn't show it charging), it doesn't respond to forced resets and the screen is completely black.
The only thing it does, is briefly show a USB device when connecting it to a PC.
I've connected it to a Linux dev computer i have laying around and i see the following device connected briefly:
VID: 0x04e8
PID: 0x1234
It stays connecting longer if i hold the power button (about 8 seconds before power cycling).
The only things i could find online were some very old threads about Samsung's DNW mode, but nothing from this decade.
I think my Flash chip might be cooked, but i hope i'm wrong.
Anyone got any experience with this?
Update
I've sent it back to Samsung for repair under warranty.
The flash chip was gone. It started corrupting writes and finally it was so far gone that it couldn't load the bootloader.
They've replaced the main board and battery (probably because they tested it and saw it was going bad), that fixed it.
So, after having two amazing Tab S (first one) and not being able to find a third, I ended up "upgrading" to a Tab S2. (Less screen resolution didn't seem like an upgrade..but hey)
After using it for about a year or so, I finally decided to get off my ass and root it. Had no problems after rooting it. Life was great. Maybe 6-7 months after rooting it, one day it booted up with an FRP lock; I didn't reset it at all so..odd..
Put the tablet aside as I didn't really have time to fix it. Few months later, I decide to pull it out wanting to use it for a project (I'm developing WebUSB FTDI drivers which also worth with Android OTG to allow a web page to access a USB device), I never replaced the original recovery, so my options were limited. I was hoping that perhaps flashing a new ROM that I might be able to keep my files versus just doing a reset in the recovery, which I'm not sure would have worked anyway (FRP) (I'm sure I've seen a device where this worked, IE, any user files were stored actually on a separate partition, thus you'd lose your apps and everything but downloads and such on the internal would be kept). I mean, I figured the chances were low but at least hire than the wipe option - not a huge deal anyway, important stuff is on the uSD.
So, I head over to Samsung's site and download the closest looking S2 rom, it's a SM-T713 (Canada, Gold/32GB/WiFi Only).. The ROM I ended up getting happened to have 4G support, so I didn't get a WiFi only ROM like I should have. Flashed it up with ODIN (AP), didn't change/flash the BL at all.
After flash, tablet booted up fine. It mentioned I would have to log in to google to authorize it (FRP lock) - no big deal, although I'm sure I didn't remote lock it. Do my login, finish the setup. Home screen. Tablet is running fine, nice and snappy.
Installed a few apps, it ran for a few days fine, then I decided I should probably flash it again with a WiFi only ROM, so I hold the power button and get the pop up to shutdown / restart, I press 'Power Off', tablet does it's shut down and powers off.
That's it. Now she's dead. Absolutely no sign of life since then. I tried to power it back on immediately as I had planned on going into DFU and plugging it in to upload another ROM. Nothing. No response. Battery was at 50% when I powered off. No battery symbol or anything when plugged in.
I should not that this was not the tablet's first boot since the flash either; it boot looped due to low battery after flashing a few times (damn samsung low battery boot loops) until I got the power supply plugged in, it was the first time that the "Power Off" option was selected, perhaps it hadn't been reset that way too; something on shutdown change something? I mean WTH?
I have tried:
- literally all key combinations for over a minute (PWR + VOL UP, PWR + VOL DWN, PWR + VOL UP + HOME, PWR + VOL DWN + HOME, PWR + HOME, PWR + VOL UP + VOL DWN, PWR + VOL UP + VOL DOWN + HOME) including while plugging it in, unplugging it
- different chargers, cables (bought brand new one), etc.
- left tablet for 2-3 days hoping it would die
- disassembled tablet, remove battery for few hours, replug battery
I have a USB power meter, when I plug in the tablet, it shows that it's pulling 0.57a constantly. I left it on overnight and it was no longer pulling current, just occasionally going from 0.00a to 0.07-0.10a. When plugged in without the battery, it also occasionally goes from 0.00a to 0.07-0.09a or so. Current usage profile is the same without the OLED plugged in. Something inside is at least slightly functioning.
No components that I notice are getting hot or anything obvious.
It was a gift, thus supposedly refurbished. The device looked great when I got it, no scratches or dings or anything, basically brand new looking so I assumed it had been a return, but upon disassembly, I found evidence that the tablet had been disassembled before, there was two-sided tape holding the screen on instead of any proper adhesive; was such a pain in the ass to take apart and not realizing that this was the case until I opened it only made it harder; regardless I doubt that any prior work could've caused this issue.
Does anyone have any schematics for this device or experienced something like this? I have meters, scope, logic analyzer, etc as I already do a bit of hardware reverse engineering and development.
The only thing I can think is somehow the boot loader got fried? Somehow the modem fw got flashed to boot loader? Is that even possible? I'm really reaching here as I'm really not sure, it's odd how it was working fine, had booted several times yet pressing 'Power Off' killed it when it was working fine. I would like to save this device from the graveyard as it's in great condition otherwise. It did sit for quite a while, so I was worried about the battery but plugging it in after sitting I immediately got the charge screen and it charged right up (even though it was still FRP locked at that point of course).

As the title suggests I have an old Z2 tablet that has been an absolute work horse for many years. I was using it one night and the Android OS prompted me that the device hadn't been rebooted in 28 days. So after I was done using it for the night I rebooted it. Only, it didn't reboot it just stayed off. I tinkered with it for a while and got it to show the Sony logo but then it just went dark again. The device is rooted and I have TWRP on it. So when I got it to turn on again I booted it into the TWRP recovery. I proceeded to clear the cache and also attempted to make a current backup. However, the backup would fail after running for several minutes. I decided to try backing up to an external OTG USB drive but the device needed to be rebooted to detect that the OTG USB drive was attached. So from TWRP I selected "reboot recovery".
Unfortunately that was the last time it worked. The screen will not come at all. When I hold volume+ and power it vibrates 3 times but still doesn't boot. I plugged it into the charger even though the battery charge last showed at 85%, but with the cable connected the charge light doesn't even come on. I tried plugging it into my computer but it doesn't detect the device has been connects and adb devices doesn't show anything in the list.
I read on a forum to try drying it out with a hair dryer and while the device hasn't ever gotten wet it has been humid here so I figured what the heck. Unfortunately that also hasn't resolved the issue.
Pretty much everything I've tried hasn't worked. Even the red reset button under the top panel just causes it to vibrate 3 times.
The device has been in this state for a week now. I was hoping maybe the battery would die and then I could recharge it, but since it still vibrates 3 times I'm guessing the battery still has a charge.
One thought I had is that maybe the internal storage is either dead or corrupted.
At this point I'm wondering if the device is a lost cause and I should just let it rest in peace or if there's any other solution. Even if there was a way to factory reset it from it's current state that would be better than having it be a paper weight.
Any suggestions beyond what I've already tried would be greatly appreciated. And, yes, I may look into seeing if I can get it serviced however there's definitely no warranty and I don't really want to poor money into it since it's probably time for an upgrade anyway.
Why is my phone vibrating 3 times and won't turn on? - Sony Xperia Z5
When I try to turn my phone on it just vibrates 3 times and does nothing after that, just wondering what the problem could be?? - Sony Xperia Z5

The device vibrated 3 times, that's good, then it is off.
"Sony writes: This is how you force the device to turn off:
Press and hold the power button and the volume (+) button simultaneously until the device vibrates three times."
Did you try to put the device into flash mode after that? I think only a complete flash will bring the device back to life.
