[Q] Need expert openion, if its Hardware or Software problem

I got a used HTC sensation XE with audio beats, with WiFi not working (GB was installed). Wifi & Teathering services always remained on "Error" when wifi turned on. Bluetooth, SIM services all were doing good. Used it in this condition for 2~ days, all went fine exept I once found it powered off while it was on wall charging.
Then I upgraded it to ICS downloading Stock ICS ROM from this thread. Which was isntalled successfully and the WiFi started to work.
It worked fine for 2 days, except my phone restarted on its own once or twice. At that moment i was using 340 MB of internal storage for apps and 750 was free. One night i was playing "Cut the Rope" and my phone prolonged a game sound and turned off, I removed battery and replaced it and turned on, but nothing happened, it remained off. Attached it to charging but no response. I left it there and after about an hour charging light turned on and it powered on.
From that moment, Phone often shows message "Low Storage Space", Hangs and then turns off. And fails to turn on again, sometimes for 24 hours. I did a "Factory Restore" from boot loader (power + voluem dwn), but its still behaving same.
Lattest: It turns on by pressing power button for 20 to 30 sec. Sometime goes upto lock screen and turns off, sometimes turns off on first screen and most of the times dies at audio-beats screen (after or before change is screen brightness). Remains dead for some time then again to same position.
Any expert openion/ experiance/ etc....
I don't have option of replacement. What to do? :crying:

But it never turns off just sitting at the bootloader or fastboot screen? Doesn't turn off while doing a factory reset? Only when trying to load software and activate hardware booting into the OS?

Yes it didn't turned off sitting idle in bootloader. But it completed its factory reset in 3 restarts; 1st right after loading stock, 2nd configuring apps 10/36 and 3rd at 23/36. Then 4th time it died on fresh Lock Screen.
NOTE: I removed SIM, SD Card in the very beggining of the problem.

I would try replacing the battery... it's about all that's left as it appears your phone is locked and more or less all stock..
Cuts down your options for things. Any sign of moisture exposure?

Haven't tried out any other battery, I tested it on voltage meter and it showed ok, BUT you have got a point; I must check it with some other battery of working phone.
Moisture:: Well there was Mist/ Fog a few days back but mostly I stayed at warm place + I kept it in fromt of fan heater after ealry episodes..

[Q] Galaxy S6 won't boot. Black Screen, Blue Pulsing LED

Ok. So 14 days ago my wife and I both got S6's for Verizon from a local big box store. (yes, 14. Today is the last day I have to take it back.)
We took the OTA to OE2 and I was able to root both phones with PingPong. Everything was fine until yesterday. Her phone wasn't responding when a call was coming in, so she restarted it by holding in the power button. Now, when it boots up it goes to a black screen after showing the initial "Samsung Galaxy S6" screen. Nothing changes. There is a teal/blue pulsing LED that doesn't go away.
I can enter the recovery and wipe cache, factory reset, safemode, etc. I've tried all of those many times. I can enter download mode and use Odin 3.10.6 to reflash OE2 and it says "Pass". After rebooting, it goes to the "Android is upgrading" dialog and goes through and updates about 248 apps, and then changes to read "Starting apps." It won't go past that screen. I left it on that from 10pm last night until 6am this morning with no change. The battery eventually went dead (from 100%). I've tried Odin many times, and it passes every time.
What are my options? When booting, the padlock is unlocked and says "Custom". I'd really like to get rid of that so I can return it to today without problems. When in Download mode, the system status says "custom".
Please help!!

I've also tried using SmartSwitch on the PC, and it doesn't detect the phone.

Update: I'm trying an Emergency Recovery with Smart Switch. It's at 52% right now. I got a serial number from another S6 so it would allow the download/recovery process to start. It's kind of ridiculous you can't get the serial number for your device from anywhere but the settings page on the phone. (Note: not the IMEI, the actual SN). It's not on the box or back of the phone.

Ok, another update. Emergency Recovery didn't work. It finished, and said that it was successful, but didn't fix the issue.
I took the phone back to the place of purchase and they tried about everything that I had already tried. They ended up just replacing the phone. They said that they never saw this issue before.

I have almost an identical issue except I have not roOted or installed any custom ROMs everything is stock . The fingerprint scanner quit working today and said it required a restart, when I restarted the phone I'm experiencing exactly what you are a black screen and a blue pulsing light. In the stock recovery screen I've tried booting to safe mode USB debugging everything except the factory restore yet I think that is my last resort.

Galaxy S6 Massive issues

Hi XDA, looking to you for answers...
The Device: I bought my Verizon Galaxy S6 straight out due to that phone trade in for $100 gift cards that happened way back in April. So I have no insurance on the device. No worries, as its in a otter box commuter case with tempered glass and I baby my devices.
The problem part 1:
-Last week just before I walked out the door for my anniversary dinner. I restarted my device and it didn't come back on.
- I plugged it in and got no light. Pressed volume +/-/home/power - and got the boot screen
- Accidentally factory reset the device when I let go off the combinations of buttons (why factory reset is the second option I have on idea)
- After the initial factory reset, I noticed it didn't go through. Rebooted and saw DM-Veritiy verification error
- Tried multiple times to get a clean factory reset until finally I got into the phone setup wizard
- Phone setup wizard froze on me about 3 times before I was able to get it to work
- Finally with finesse and some luck, I was able to get the phone partially restored but I knew something was fishy
- Brought the phone to Verizon which said I have no insurance, the only thing I may have is a manufacturer warranty with Samsung.
- The rep tried to factory reset the phone, however the DM-Veritify verification error came up again and could no longer continue.
- After some time there, I felt like I was wasting my time, Figured I would this myself.
- Went home and flashed the STOCK OS on my galaxy s6 with ODIN.
- After ODIN, and many OTA updates, I was on 5.11 and restoring my phone
After all this, the phone worked PERFECTLY FOR A WEEK
The problem part 2:
- Was in a parking lot to get some groceries, sent a text and put the phone in my pocket. When I looked at it again, the phone was off
- Tried to turn it on... nothing... I held the +/-/home/power buttons again and rebooted normally
- Phone started up just fine but froze after a minute.
- If I get the phone on, it will either freeze/hard-lock or when the screen turns off, then its just turns off, or restarts itself to failure
- I've tried to reboot into recovery volume +/home/power to wipe the cache, however I get an android in distress
- After a few attempts to get into recovery to wipe the cache, I managed to get past the distress icon and press get the menu selection down once before the device froze
- After more attempting to to wipe the cache. I don't even get the android in distress icon anymore, just the blue android screen hangs
- If I use all the buttons to reboot normally - the phone will freeze or once the screen turns off, its off.
thats it
I feel like I just ate $700
XDA please help

Phone freezes in "recovery mode" 3 seconds in. Managed to get one wipe cache in.
Getting a "system rev. check fail device: 3 binary 1 error" error when trying to flash ODIN.
Guess you can't flash stock OS from 5.1.1

got a factory reset to go through just fine. Restored phone for 30 minutes and proceeded to use it.
Seemed fine and then froze while texting.
Seems to be randomly freezing and then a sudden restart.
Contacted verizon for the number to call for warranty send off.
*looks around* I see MULTIPLE issues regarding the S6 randomly restarting.
I should have got the Note 4

Hi,
Sorry, but if it keeps happening persistently even after factory resets and successful stock installs, I'd call it a hardware problem. The best thing you can do is contact Verizon or Samsung and try getting a replacement.
All the best,
~Lord

How to restore into operation LG G2 D800 phone that says "Fastboot mode started"?

How to restore into operation LG G2 D800 phone that says "Fastboot mode started"?
Current problem: phone is not operational (does not boot properly).
What I see:
Boot Screen 1:
Phone appears to boot as normal, makes the start-up sound, then it shows a white message box on a gray-screen background. The message box says "Unfortunately, Settings has stopped."
It gives me an option to click "OK".
Clicking OK, message box disappears, screen momentarily flashes an all-white background, (which sometimes changes into black and sometimes not), and then it goes back to the message box.
Boot Screen 2:
"[xxxx] Fastboot mode started" on a blank screen,
where xxxx is a number. 6180 one time, 9790 another during 2 individual boots.
Then the phone just sits there doing nothing seemingly indefinitely.
I am not sure yet how I bring those two different boot modes up but via pressing Power and / or Power and Down buttons in some fashion.
How do I fix this? Is my device bricked?
How I got to that screen
I was using a web browser or some other app on the phone when I have received a text message. I clicked on it inside text box to reply. But changed my mind, and clicked back on the background app. Suddenly the phone shut off unexpectedly. I thought it was related to phone drawing suddenly high battery power, not receiving it and shutting off as sometimes happens on very low battery power level 2-4%. However, my battery was charged over 40% so that was most likely not the cause.
Possibly relevant history (anything that could be contributed to the above):
phone worked okay for a while (since purchase)
~1 year in I tried rooting phone with towelroot/other options unsuccessfully. Gave up. Was never able to root the device. Lived with is as is for a while.
~2 years since purchase, somehow Bluetooth option started failing to turn on. Trying to fix that via doing a Factory Reset did not help. So I lived with BT being non-operational
A week ago I swapped SIM card with my buddy for a week, then swapped it back. Phone kept working as normal.
Today I charged the phone perhaps not using the best power source - it is possible I may have damaged phone using a questionable quality charger. Possibly. This could be the issue. However the phone seemingly worked fine after that for 2-3 hours.
Since my unexpected Shut-Off (most recent), I tried rebooting the phone, but that does not work as expected. First time it got stuck on LG screen forever. Kept pressing Power button, or Power & Down buttons to try to make it come alive. Other two times it brings up a message with "[xxxx] Fastboot mode started" on a blank screen and then it just sits there doing nothing.
Another boot, the process went further, past LG G2 logo, into white screen, and then it brought up a message "Unfortunately, Settings has stopped.", I clicked okay. It looped back to bringing up the message. I clicked Okay over 10 times, it was stuck in a loop.

Please Help! Stuck at boot screen...

Hello. Sorry in advance if this is the wrong thread. I own a pretty old 1 year old tablet that currently has a problem.
Important info: Android 5, No access to a computer for 2 weeks (vacation), slightly cracked screen (still works), I had to install a Play Store apk as the one I had previously was corrupt. Tablet was functioning fine until the moment of the incident (except for the play store apk, which I later fixed).
Minor detail: Once the screen turns on after a restart the pixels near the top of the screen seem to turn purple for a second when I tilt the tablet.
Here is the story:
I was watching a YouTube video and suddenly my tablet froze. I thought: "Uhh, another freeze how annoying," and waited for it to load. I did not unfreeze. I thought: "Well, I guess I'll be fine if I turn my tablet off and on. This is where I got worried. My Power key was not responding. I tried the volume keys. Nothing. I tried connecting a mouse and moving it around. Still nothing. I thought "Ok, lets try restarting it" I did that by holding the Power key down for 10 seconds. To my relief, it turned off. But when it was turning back on again, it was at the loading screen for a little to long. It usually takes 5 seconds to get past the loading screen and enter the boot screen. I decided to wait. 1 minute: nothing. 5 minutes: nothing. I got worried. I tried restarting the tablet again. I restarted successfully but was stuck at the loading screen again. The was no movement on the screen. Only the loading screen. I decided to try the restart backup button which I could activate by putting a pin in a small hole at the back. It had the same effect holding down the power key had. I decided to ue my backup plan: recovery mode. I successfully entered recovery mode. I chose the option "clear cache" and tried to boot again. No changes. I did a scan for any root errors. it said that there were 5 errors, but there was nothing I could do about that. I tried doing a factory reset, then booting up. The reset was successful, but I got the same effect as always. No changes. I gave up and tried to google a solution on my phone. Most of them told me to install a PC program, but one told me to do the same thing I already did: reset, restart. So I decided to let the tablet sit with the boot screen for 2 hours. When I came back, there was no change at all. I tried searching again for a solution. A YouTube video said that the boot time after factory resets may be long, so I decided to reset and let it sit for a bit. 20 mins later, no changes at all. Finally, I gave up and now try to ask for help here.

Was your device rooted? Did you have TWRP custom recovery installed? If you don't have either of these two things then your only option is to flash the stock firmware via PC.
Do a google for:
"Return to stock (your model number)"
If what you need is out there somewhere, that woll find the instructions, the tools and the file(s) you need.
