Stuck in boot loop after strange problems (blank screen/settings app FC)

Hi guys,
I have an HTC Sapphire (HTC Magic from Vodafone UK). Problem with it this morning stopping me using it so urgently need some help!! I've included all details I can think of below to help someone diagnose the issue.
Been a very happy CM user for several months now and upgraded to 5.0.8 just a week or two ago. I did a full backup and wipe and haven't had any problems with it until last night.
Just before going to bed I noticed when pushing the menu/red button to turn the screen on, the keypad lights would light up but the screen wouldn't turn on. This happened a couple times in the last week but taking the battery out and restarting resolved it before. So I did that last night and it started up again and I went to sleep.
This morning I went to use the phone and it seemed a little strange, like some of my settings were back to default (security lock pattern went red when wrong, no battery % in title etc.), but the phone worked and I could make a call.
I then tried to configure the settings but as soon as I tried to enter any category I got FC's in the Settings app. So I restarted...(strangely silent/airplace modes weren't options, only reboot/switch off)
This time after the red Vodafone boot logo the phone got stuck in a boot loop - (CM specific: the 4-colour X swirl would be OK but after 3/4 silver X swirls the 4-colour one would start again) and this continues until pulling the battery out.
Left battery out a while but no help.
Went into recovery console and wiped cache - startup took a lot longer but still eventually got stuck in a restart loop.
Will reflashing CM help? Should I bother with a wipe (would rather not cause no backup!)
ANY OTHER IDEAS??? I'm really stuck/frustrated/depressed right now as this is my only phone and I'm not even living in my home country so am really cut off right now.
Thanks to anyone in advance.

[INFO] Random Reboots aren't True Reboots

I think many of you are misinterpreting the "Random Reboots" you're experiencing. Unless the screen goes completely blank, then it is not a true reboot, if all it does is flash back to boot animation it is just the graphical shell crashing.

Good point, I did notice that it booted up significantly faster than a full reboot when it happened to me before and that it only dropped to the boot animation.

That makes a lot of sense actually

Thanks for the suggestion - that does make some sense. Is there a way to verify this, though? In my case, my DInc will be in a stand on my desk - screen off, so I can't actually see what happens - when I'll hear it vibrate, and I'll notice the white HTC screen followed by the boot animation. It's only done this since I rooted, and it has done it with at least three of the ROMs I've used.

Yeah, same deal. I have learned to do "real" reboots, especially after rooting. What I mean is actually turning it off, counting to like 20 (maybe pull the battery), and then turn it back on.
Recently I had an issue with the capacitive buttons not lighting up at all so I tried a "quick" reboot (the kind that requires root) and it did nothing, then I tried a "real" reboot and they work fine now.

Agreed. I can confirm the Atrix is not doing a full reboot. I had a call on speaker phone then all of a sudden my screen showed the boot animation and I could hear the other person talking for an additional 15-20 sec while the phone finished "booting". Our conversation was not ended until the home screen came back up, at this point my bars/service dropped to no service. Also, I have not rooted or modified the Atrix, its stock.. w/LauncherPro+.

I had those "reboots" twice now. Once while using Maps and once while sitting on my desk not being used. I was also using LauncherPro+. I wonder if that might have been part of it. I stopped using LP+ and haven't had a "reboot" yet (knock on wood)

Phone crash after battery died!!

my battery was running low, (and coz poor battery issues with JPY), i didnt notice when it switched of. normally i use the power button to turn the screen on to unlock, but instead i realised the phone had been off as it was now booting up...it booted up fine went into the homescreen and then vibrated once and powered down.......now it was powering down for a long time and occasionally there were vibrations and the lights on the home keys were constantly on. the screen was black. i got home and tried to charge it but the progress bar showed no progress on charging, i tried to switch it on but it would go to startup screen vibrate cupla times and power down. so eventually had to do a hard reset in recovery mode. tried every option but in the end had todo it by wiping data.
now the thing is, is this supposed to happen? if ur battery suddenly losses power ur whole fone will screw up?
for future ref if ur battery dies dont try to switch ur fone on until u got some charge in it and use the home key to put screen on..

Sounds like it could have been faulty firmware .
JPY does not have a significant battery drain problem per se .

Black screen, vibrations and no boot after restart
Hello! I had almost the same experience (Black screen after reboot and occasional vibrations) only mine refused to boot even after memory wipe and after flashing new roms.
Was your phone rooted? Because I think rooting a 2.2.1 rom (XWJS3) was the beginning of my nightmare. keep in mind that the phone was working like charm for two months. This was the second time I had a problem. The first time the phone started after performing a factory reset by itself!
In case this happens to you next time and for every non experienced galaxy player (like me) reading this:
Don't panic! Blank screen, vibrations and no boot doesn't necessarily mean a hardware problem. Finally I managed to fix it flashing eclair and repartitioning with pit512. Now I'm a happy XWJS8 user
And a question for the experts: Any clue why this happened? Is it really a rooting issue? Can a cheap Chinese battery from ebay cause this?

everything was stock on mine, no root.......maybe thats why i could recover it??!!

Maybe! and I hope the reason is faulty firmware as JJEgan says. If this is true, your phone will be fixed by the next update.

I was very urge... the same happened again. It's been a month of smooth functioning and now after a simple restart, the device doesn't boot for absolutely no reason (Stuck on black screen constantly vibrating). Since my phone wasn't rooted, and I haven't seen many people talking about a problem like this I suspect:
1. Faulty hardware (for a few devices including yours and mine)
2. A Bad app.

Contacts Vanished
Hey Everyone
Im having similar problems, i updated my sgs to the js7 version of froyo, then rooted it with oneclick method. this was as i got the phone a month ago. Its been smooth sailing since then. But last night the phone powered down and wen it loaded up it had no contacts, my sms where still there but all the apps had a force close issue none worked. so cleared the cache in recovery. Still nothing so i did a factory reset and once loaded up. i formatted the sd and internal within the settings option. So the phone was now clean. I then connected to pc luckily had backups so installed titanium restored all my apps n settings. Using kies restored my contacts n thanks to an app called sms backup i restored those.
So all was well and worked again. I didnt restore the apps i had installed within the last week to make sure it was not a faulty app. I was happy, but now tonight it did it again. No contacts again.
Pls help
Any suggestions

That's exactly how it started for me. One month after rooting froyo 2.2.1 Suddenly everything force closes and the device hard resets by itself. I reinstall all the apps and then after one month and performing a simple restart, it refuses to boot. Stays in a black screen and vibrates every some seconds. I flash a new rom but does the same. Problem solved after repartitiong and flashing original eclair with pit 512. Reflashed a 2.2.1 rom and everything works perfect (the phone now is unrooted and with a nice clear stock rom). But then after one month again (!) I realise that some videos refuse to play. Trying to restart and craaash. black screen, vibrations and no boot. Did the same again (repartitioning and flashing) and now I wait for another month to pass and lose an hour of my life to do the same again. No idea why this is happening. Is it possible that rooting messes with something that stays faulty after restoring the file system? is there an app that we all installed and caused this mess? please this is the most serious problem I've red in this forum and still a mystery. I believe this thread should be sticky and we all share similar experiences because this looks completely random!

Unresponsive screen

Android 2.3, 407band, DSC 7.0 rom, Go launcher (default), Zeam launcher (secondary)
Today while using an app called wallbase, I hit the home button while the app was setting a wall paper for me (normally I wait until it says wallpaper set). The home screen popped up but then Go launcher had a FC error (which it has never had since I've been using it). It had the option fc or wait I hit wait. Next my wall paper went black then my screen followed by two vibrations and a notification sound I never heard my device make.
I rebooted to the lock screen with a black background and no service on the screen. It was unresponsive to my touch and after about 10sec. it gave the same two vibrations and sound from before then shut the screen off. The power button did not turn on the display so I had to hold it down for about 20sec for it to reboot to dell logo. From there i went into nandroid and flashed severals roms loaded to the lock screen, rinse/repeat, to find the same result (simple streak, streakroid, older version of dsc).
I reset permissions, wiped cache and dalvik, calibrated screen. Want to avoid a factory reset because I don't have a backup.
Help guys? Mods please move to the appropriate forum.

If all fails and you don't have another alternative.
install the DSC v0.70 update, it shouldn't delete your 'data'.
I would backup your streak, better be safe than sorry.

So I tried letting it sit with the battery out for the night (6 hours) and booting it up this morning with the ac charger. It loads to the same lock screen (standard screen with black background and no service on screen) and all my start up apps loads, it even showed me a text notification. I did notice that the time was wrong though and never changed.
Any one have this issue before? What suggestions are there to combat this? The G.Note doesn't fit into my budget right now. May have to factory reset this and sell it as a last resort.
Help guys?

Outlook for this issue looks grim. Seem others with a similiar issue on different devices have had to factory reset or return it to manufacturer.
Before I do that, is there are any possible way for me to backup some of my app data?
Anyone know if Dell still helps with this device?
I use the app cadrebible often(its the only one I really care about) but it doesn't auto sync/backup and my last manual backup must be from Dec2011 - yea makes me want to cry.

I can load into fastboot, so is there a way I can uninstall a few apps I suspect are causing the issue? Move files from the phones to the sd card/computer?

factory reset. Mod feel free to close thread. -- yes im crying.

Did you try calibrating the touch screen?

Galaxy Note 4 just went high

So, I know this phone is old asf but I can't find any tutorial and I really don't want to flash my phone for the 30th time again.
I just tried installing LastPass Authenticator (for 2FA), and when I launched it my phone just turned off, I tried booting it up and it went past the splash screen to the T-Mobile logo, and after that just shut off.
Now it'll just stay on the Splash screen for a bit, it won't even get to the "Samsung" animation, and just shuts off. It was stock ROM as well as stock recovery as well.
Don't know why this is happening, but its the second time something similar has happened. I really don't want to reset the phone due to the data I have on here, so any help is appreciated.
