I've looked all over for the answer to this, and I've tried multiple things but nothing seems to be working. Last night my phone froze (for no apparent reason) so I pulled the battery. The first boot screen came and went but the 2nd doesn't show...it stays blank and then eventually I hear the noise my phone makes when it's fully started up, but the screen is still blank. I have to push menu and the home and call keys a couple of times to get the screen to turn on, and then I can see everything seems to be up in the background, but when I go to unlock my phone it doesn't recognize me pressing the buttons (to unlock the SIM) so I can't get any further. When I do home+power combination, the screen with the triangle and exclamation point comes up, but it won't recognize any of my button presses. I tried to use fastboot to bring it back, and it says everything went through but when it starts back up the same thing happens, it won't recognize me pressing the screen to unlock the phone. It will take maybe the first 2 keys I press..and it will lag while it takes them...but after that it doesn't take anything else. I don't know what to do so if anyone can help or might know what could have happened. Like I said, I was just on the browser last night looking around and it froze so I pulled the battery. Oh and I'm running JF 1.50 if that matters. Thanks guys.
Did you install hardSPL?
If not, maybe you can create a goldcard (search in this forum) and flash the basic system on it again!
I have the SPL for Sapphire ported to Dream.
I might have to take it in to T-Mobile because it boots up and just automatically freezes at the main screen.
The only thing I'm worried about is that I changed the first boot screen so if I do end up having to get a new phone I'm going to have to pay for it
wipe wipe wipe
no need to take it to t mob just wipe take the sd card put it in a sd card reader load up the root/hack rom and go from there no need to take it back cause t mob will tell hell no when they try ro boot it up
I don't know how to wipe it without going through the bootloader and that won't load up.
I also don't know how to flash an update without going through bootloader so I'm stuck.
try this
pull the battery hold down power + home put battery in without taking your fingers off thoses buttons wait till bootloader loads. it happent to me an endless loop everytime i pulled the battery it would power up without touching the battery so thats what i did
ok, weird issue.
Yesterday I came back to my TF having left it inmy bag for the day, and it would not turn on at all.
I tried various things and then decided that the battery must be totally dead.
I left it to charge over night, and come the morning was able to watch it booting.
However once It finished boot it goes to black screen. Pressing the power button sometimes gives a flicker of backlight and then goes blank again. sometimes it even gives a glimpse of the screen.
Plugging in the power sometimes gives a longer blink of the booted ROM.
I have tried a cold boot, a full data wipe and I have used NV flash to fully reinstall the ROM (Prime 1.8)
After the full reinstall I go through the Google initial setup process without a problem, as soon as the rom boots I am back to the flicker of screen going off..
Does anyone have any ideas??
Still got the problem, does this sound like hardware to anyone else?
if the screen doesnt work during boot it is hardware problem. flash ur rom again or wipe it

Screen works fine during boot
Done both of your suggestions unfortunately, as I stated in my original posting.
I am going to try going back to Stock, and assuming its an app NOT restore any during the rebuild process.
Hello, my Photon started acting up really weird. First of all, it was really slow. I thought it's because I had like 150MB left and it was nearly full data-wise. However, I erased most of the data, and left it with 3GB left. Didn't work and it got worse.
I have these stripes around the display (just at sides, not at middle), while phone is turned on. Doesn't matter if in system, or at boot logo. Doesn't matter, because whenever I get to system, I can be in system for like 1 minute, then every application starts crashing (Apex launcher, Google play, whatever you pick) and I basically can't get anywhere. Also if I go to sleep mode, phone is basically dead and it's pure luck when I will turn on phone again. I am trying every few minutes and it's worthless, because any time I get to system anyway, I crash after few seconds.
What to do? I was planing to install custom ROM yesterday, but never got to that, because this all started to act up. So what should I do? Reset system? Any other ideas? Is phone dead?
Sorry for bad english, no bully please.
Thanks in advance
Update - now when I am trying to start up my phone, I have just black screen with white lines in the middle. Then phone shuts down. I will give more info when I will be at home and can get phone on charger
Well definitely try to charge the device up. You might try re-flashing the stock ROM using RSD Lite... Although from your description I fear your issue may be hardware related.
Could turn device on. Apparently that black screen with white lines was just discharged phone. When I put it on charger, I could again boot into system and it was working until I pressed power button to go to sleep mode and phone is again dead. Will try to flash RSD Lite later today and will post what happened

Charge the device as much as you possibly can before doing anything with RSD. Ideally you should have at least 50% battery in the device when flashing anything.
This is really miserable. I can't really get into bootloader. Because phone after that 'crash' or whatever you want to call it is dead and I can't even see if it's turned on or not. Basically I am randomly waiting when it's gonna restart and then I just get into system. Even if I fully discharge it, it will have black screen with white lines first, it flashes quite couple times and then it will finally boot into system. Also I remember it was ***** in past to get into recovery. Can I do anything from system? Because as soon as I don't turn off my screen by power button, phone is working, though it has those lines on side of LCD (I will try to borrow camera from someone and post it here today).
I set automatic turning screen off for 10 minutes and I am really careful about pressing power button. Sucks there is only option for just 10 minutes, so I have to tap on screen at least for once every 10 minutes or I will not have working phone. **** my life, really.

Why can't you turn the phone off and charge it while off, or boot to recovery and charge the phone in recovery?

About charging it while turned off - Can't because when I try to turn it on again, it's roulette when I get finally bootloader logo and not black screen with white stripes.
And boot to recovery. Is it possible to like download some command prompt application and boot to bootloader from there? I know when I had my G1 (and when I actually understood android ) you could boot to recovery or bootloader via console. I have astro installed on phone, so downloading some console application and installing it shouldn't be problem.
Btw as we are speaking, I tried to call someone and I basically get same thing like when I am going to sleep mode, I get black screen and now I am just waiting, when phone will eventually want to restart itself.

Still sounds like some sort of a hardware issue, is the phone new to you?
You can certainly force bootloader mode, in several ways. When it's off you can hold power + camera and it will give you a choice of what to boot. When it's in Android you can do "adb reboot recovery" or "adb reboot bootloader" depending on where you want to end up. There are various apps which can also do this for you, if you are on the stock ROM but rooted.

Phone is not new. I bought it used about one year ago.
I am not entirely new to android, but I didn't have android phone for 2 years and then I got this one. So I am really pretty **** with android atm
I will try reboot to bootloader from some console application.
I am rooted, opened bootloader, stock rom
Finally got into recovery, what now?
Also, when I once booted to system, I downloaded some root checking app, and root apparently isn't here. Well cornholio told me it is rooted back when I gave him my phone to perform sim card mod, but whatever. However, I am in recovery, but device is not detected by RSD Lite.

Well reading back thru this thread, I was suggesting RSD Lite back to stock. I'm not really sure what you want to achieve tho, what your "final" goal is here.
I'm not even sure what kind of recovery you are booted into - stock recovery? CWM?
Either way, if you want to RSD the phone back to stock, you need to boot into fastboot/bootloader mode - not recovery. Just make sure the phone is charged up as much as possible before flashing in RSD.
Oh, sorry - misunderstanding from my side, thought I can switch to fastboot from recovery, oh well.
Also yeah, stock recovery.
To spread more facts - in case somebody would have similiar problems, when I try to just turn phone on, I have zero success what so ever. There's just this blank black page flashing every few seconds. However, when I remove back cover, I somehow force phone to load to bootloader logo, then I finally get chance to force phone to get to recovery. I will try to get to fastboot

Not sure if stock recovery has adb enabled, but if you have adb you can 'adb reboot bootloader'.
Otherwise do the power+cam trick I mentioned earlier.

Did you remove the getvar lines from the xml file...?
Yes
Weird. I only recall seeing that when people were trying to downgrade... but you are flashing 4.1.2.
The phone is in fastboot mode? What happens when you click "show device"? The "Device Properties" section is eerily empty.
I know it sounds shady, when I am coming back here again in few weeks, just been a bit busy lately, sorry about that.
However, somehow I got phone to flash it. The white graphical lines on sides dissapeared, however I got some new bug - I can't use phone in portrait mode, just in landscape - aka I need to swipe keyboard to have phone working. Also, that thing when phone completely stops working now occurs only when I am in that portrait mode, but I can restart phone this time.
When I finished this, it was midnight so I went to bad, so I tried to set up alarm, if it's gonna randomly shutdown like before and unfortunately, yes it did. I was waken up with this classical white line graphical bug black screen and had to reboot the phone. Oh well, managed to boot to system and it takes 5 minutes to fetch sim card (I have sim card mod from cornholio) and as I said, those white lines on side aka mysterious graphical bug is back.
Unfortunately for me, starts looking like real hardware issue now
Hello, recently I started reading comics and found my old tab lying around so ill give it a go
First thing first it wont boot becaue it had no charge obviously (been there for like some years), then I tried to plug the charger but to no avail
I cleaned the contacts of the charger with a dry brush and start charging which then my tab starts charging!
when I booted, I think it was CM 12 (or 13? the one with andy I believe) and everything is force stopping.
I then tried to go to recovery mode and wipe data, but when i rebooted it it just stuck with the splash screen (the one before bootanimation)
I turned the tab off and tried to boot to download/recovery mode but it would just boot me right to the splash screen again, which mean i cant go to TWRP or ODIN.
And it doesn't always want to turn on, sometimes it just stuck there with black screen (not turned on) even if i press power/combo button, sometimes it pop up to the splash screen. what i notice is that i should wait for the charging indicator to show up before i can try to boot again (i got enough juice now, 56% the last time it turned on)
also one thing i remember is something about F2FS but im not sure what that is, but that might be a clue to my situation so ill just write this down here
Hi
Same here with P5110 and Slim7. I can't start it anymore....
I didn't use it for some time and then i charged it to 100% and it started but everything seemed to lag. Then i turned it off and wanted to look for another rom or a newer build. But i can't start it anymore. when i plug in the charger i can see the charging screen but beside of that i can do nothing. It has no effect when i push the on/off button or anything else...and it has to be at nearly 100%...
Hey everyone, I'll start by saying I'm new to these forums, so go easy...
I've had an S7 (Verizon SM-G930V) for probably 3 years, recently it randomly glitched/locked up (screen had strange color bars through what I was looking at) phone restarted and then was stuck in a boot loop. It's never been wet or dropped hard and is in really good shape. I shut it off and attempted to re-start with the same results... Got a new S20+ so I at least have a device, but I'm determined to get the lost month on the old S7 back since I had a backup from early Feb.
I tried a new battery since that was mentioned, didn't change anything, however in messing with trying to get the phone to boot have discovered a few strange message screens and behavior...
1. Phone will eventually stop responding to key presses, have to pull battery connector, wait, then it will re-boot, but every time the blue 'Recovery Mode...' is displayed. If I touch nothing, it will boot and start 'installing updates' but eventually lock and restart. At one point it made it as far as the Verizon screen, then died.
2. I can get the phone to to into the recovery menu and it will respond to commands. I've tried restart normally, boot to safe mode, and shut down phone normally, all of which result in the same restart and recovery mode message and then the lock during the update.
3. I have successfully made it to the download mode screen a few times, but don't have the knowledge of what needs to be done there and which files I would need to upload to it to make that work. (phone was totally stock rom) It had recently updated to the latest version available from Verizon which I think was 8.0?
4. Now I have found a new error screen which I have not seen before... The little Android guy has X's in his eyes and a large yellow sign with ! in it says 'No Command' and then the phone restarts? It also during that finally responded to being plugged in via USB charging, however normally it shows no signs of charging other than being warm and actually charging the battery (verified with a meter)
5. When the phone is on, it gets warm quite quickly (it's still split open and the tin covers are warm, but not hot)
Hopefully someone can help out. I wouldn't say there's anything too critical on there, but there are some pics I'd really like to have back :crying:
Thanks everyone!

If what you've described is correct, all of the solutions involve flashing the stock firmware which will of course wipe the device.
Were your photos not stored in a folder on the SD card?
There is a chance you can recover the device using Samsung Kies with the emergency recover option but if you've encountered the "no command" screen it's not looking good.
Unfortunately I did have an SD card installed, but I normally kept my camera pics on the phone's memory, since I have had an SD card fail as well and lost everything on there.
So this took an unexpected turn yesterday pretty much right after posting this... I've been messing with the phone, unplugging the battery each time, and have managed to get into different menus which kept making me think that something still had to be working if I could do that. Well, after leaving the No Command message on the screen it magically booted into the Recovery menu with (finally) the option to wipe the cache partition, which I did and rebooted normally. Believe it or not, it booted normally and into the OS like nothing ever happened?!
I instantly plugged it into my PC and ran Smart Switch which started taking a backup! About 25% though the device restarted again and was really warm to the touch on the RF covers inside. Bummer...
So I figured heat was now the issue for some reason... I waited for it to cool and then reinstalled the SD card and figured, if I could get it to boot long enough, the SD card is a quicker transfer and I'd just use ES File Explorer to try and do a photo dump to the SD card and see how far it would get. It actually made it all the way through and gave me enough time to grab some other stuff before getting hot and restarting again.
I believe the overheating is being caused by my opening of the device though... Currently I have the antennas removed and the speaker so that I'm able to quickly access the battery connector (which BTW seems to be the trick here to this working) But inadvertently, without the larger wireless charging coil in place, it relieved the pressure on the motherboard and broke the thermal paste connection between the chipset and the copper heatsink (I didn't tear it down further to check, but I can hear the 'sticking and peeling' when you press down on it).
I think what I'm going to do is apply pressure with a chip clip or something similar (non conductive) and see if I can grab a backup again before it restarts. After the cache wipe the phone seems to understand that it's plugged in and charging now which is a new thing as well...
Sorry for the long winded posts, but if this at all helps even one person with the same situation as I have, maybe that'll be worth getting lost in here
