[Q] Boot problem on Samsung S4 I9500

Good morning friends. I got a problem with my Samsung Galaxy S4 I9500. It's weird. I was looking at my Gallery when suddenly the phone power off. When I press the button of power on, it appears the screen of "Samsung" but it didn't make anything. So i took out the battery and then putted on again, and the same thing. After a lot of tries, my phone power on...but when I but my code for unlocking the screen, the phone power off again. I made this many times...and the same result. So I decide to put the rom again...so I use Odin and reinstall the firmware. Everthing was alright. My phone power on for a while, but when the screen get lock and i put my unlock code, the phone power off once again. I don't know what it could be. Its really weird. I have been looking for bootloop troubleshooting but still not getting anything. I hope u can give me a solution. Thanks in advance.

thanks for the reply. I did the two fist things already, but I haven't try with a different battery. I will try later and I will post about it. In your knownledge what else could be?

good battery is very essential for a well running device...
no idea about other reason, it might be a hardware failure.

Motorola Droid RAZR/Cyanogen mod problem?

I've had this Motorola Droid RAZR for like two years now and a friend of mine took it and worked on it, adding something called "Cyanogen Mod" and he 'rooted' it I believe? Ever since, phone has worked great. However, today I tapped the home button and the whole screen had a weird visual glitch where the wallpaper was entirely intact but the icons and such were only half appearing, like someone scratched them out with fingernails or something. It would go away and come back so I got frustrated and rebooted my phone. It starts up normally and goes to this screen where you can do different stuff with Cyanogen mod (like changing the rom? or changing boot options) and usually I just continue past that because for 1) I know nothing about it and 2) It always was fine. But when it did the typical boot up, it just skipped back to the first screen you get when you turn the phone on and repeats. It never goes to the second part of the Cyanogen Mod where the words appear and the little thing spins, it simply skips back to the screen you get when you power up and repeats. It keeps doing this and I looked online how to fix it, tried about twelve different things (like restoring different aspects and using different roms or making new roms) and it just didn't work. Eventually it got bugged out where the screen was just black, couldn't get it to do anything but reboot and go back to black. I let it sit until the battery ran dry I believe and now I'm at a brick wall.
Is there a way I can totally just revamp and start fresh? Like remove all of it and reinstall Cyanogen mod/the OS and all that jazz? I don't mind losing everything if I can just keep the phone, I don't pay for a cellphone and I don't want one I just use the droid for texting apps/games/reddit/etc. If anyone could help me save this thing I'd appreciate it.

Hello? Can Somebody help me out, I've waited a couple days now and no one has said a thing?

You have safestrap installed, correct? If so, what version?

How would I know if I had it installed? I remember when I booted up the phone something came on with a picture of a little robot that said "Safestrap Enabled" and then when I had this problem it was saying "Safestrap Disabled". I can't get the phone to turn on right now though, is there a way I can check what version I have another way?

Ah. I see. First. try entering Safestrap menu upon rebooting, instead of allowing it to boot normally, and look at ROM slot and see if custom OS' ROM slot is active. If it's there and is not active try reactivate it. If it won't budge, get microSD card and find XT910 (RAZR - spyder) CM 11. If you don't know what to pick, I will look in a bit.

Just tried booting it up, nothing is working I think the phone is dead. I plug it into the charger and only the notification light on the top left goes on a blueish white and stays on as long as it is plugged into the charger. Nothing will turn on at all and the phone doesn't seem to respond to anything. Is my phone just dead..?

Soft bricked. Try pushing both volume down and up button while plugged into either computer or charger, and hold down power button until it boots. I hope you won't need to buy Motorola factory cable at this point.

Let your device charge for a few hours until it boots up. Then boot it into APfastboot and flash the stock firmware with RSDLite.

In English please?
Edit: Just plugged it in like you said and instantly the boot screen came on rather than simply that silly light so I think my phone is improving but I still would like to entirely revamp it or redo it or whatever you wanna call it so that everything is fresh and new and my phone is okay.

Good. I think it could be because the battery died somehow. Good thing the protection mechanism on the bootloader didn't have the wild idea of disabling the phone.

Samsung galaxy s7 edge wont get passed the att logo screen.. HELP

Iv done all i could find on here to do, please heop me get my phone to boot up!!!

Perhaps you should give a bit more info. What were you doing before you got this issue. Were you updating, are you*rooted, what version of firmware and whose network are you on.

Sorry, I am rooted and I am with att, it was Working fine until I tried to put xposedon it , after I did that it went into this boot loop. I used Odin to root and it rooted fine and still worked. Then I attempted to put xposedon and it messed it up. I'm on att and 6.0.1. Let me know if you need to know anything else. Thank you

Tried goin back to factory
I also tried using Odin to go back to the original firm ware, now maybe I did something wrong but I t failed everytime I did it. Any help would be appreciated

When the same thing happened to me, I was stuck/frozen on the AT&T logo screen, I left the phone to drain all the way down. When it finally drained the battery and shut down, I was able to plug in the phone to my computer and get back to the download screen. I let it charge up a little bit, then I Odin'd it back to stock (PI2). I have since been unable to root again, but the same thing happened before. It was a couple months before I tried rooting again. At that time, I was successful. Someone else may have a more elegant solution.

Couldn't you just have tried a manual reboot? Just hold power and volume hardware keys for 12 seconds. Once it resets enter into download mode.

I don't believe that but I guess it may be possible and the hard restart buttons are power and volume down for about 10 seconds, seems like an eternity before it reboots lol.

[Q] Galaxy S4 just died out of nowhere?

So, long story short, my GS4 just froze up and shut off on me this morning while checking out Facebook on the phone, and now it won't turn on no matter what I do.
Removing the battery and holding the power button for a few minutes partly resolves my issue, as I am then able to actually power on the phone, but then it just gets stuck on the GS4 logo and doesn't boot into the actual system. I was also able to get into Download mode at one point, but I wasn't sure about flashing new firmware from there since my phone is rooted and has a custom recovery installed, and maybe that will interfere with the installation.
Anybody got some input on this? I am kinda freaking out here, would really love it if I could fix this thing without taking it to an overpriced shop, who maybe wouldn't even accept it due to it's 'modified firmware'.

if it boot into recovery, factory reset your phone and wipe cache, it's a painful solution but it's functional.., I've had the same issue on another Samsung phone and that fixed it, also I don't think flashing stock rom would interfere with anything, you can try that as well.

I am about to go crazy with this evil phone. j320a variant with complete stock firm

Ok, so this all started about a week ago. My dad has had this phone and for the most part has enjoyed it. The other day he calls (from the house phone) to let me know that his phone doesn't work. I was expecting the typical black screen so hold all the buttons to force a reboot and boom hero for the day.
God no. This phone would suddenly not boot properly at all. I mean I had trouble getting stock Recovery mode to even come up or download mode. I bought a new battery thinking it could help. Twice now I have managed to use ODIN to reflash stock firmware of 7.1.1 . Both times the phone would be fine and suddenly it would turn off and bam the same thing over again. Firmware screwed and it doesn't want to turn on reliably. Recovery mode would display all sorts of errors with mounting /efs and dm verity errors....
This must be a hardware problem right? I don't know what else to think at this point. Is it possible the restore of his backup from sammy cloud is corrupting it? I am willing to try this one more time and not restore any of his files or is it hopeless? Is there something fried?
And just for the record, I am not new to ODIN/Rooting/Custom Roms/ etc but at no point EVER has this damn phone been attempted to be rooted or anything. I hope someone has something positive to share or just put me out of my misery so I can destroy this f******* phone into a thousand pieces.

Has anyone ever had an issue where the plastic back cover is somehow causing the phone to short out or overload which makes it freeze or turn off? I swear this back cover is the cause of all of this. Last night i reflashed everything and really just forgot to put the cover on. It stayed on all night without a single issue. I rebooted and powered down multiple times and it turned right back on. Then I put the back cover on and what do you know, difficulties with powering on and freezing.
On the top right above the sim/microsd slot there is that spot with metal looking conduction material or something and it is also at the bottom near the charge port. What are those things? At this point the phone has become a pet project and I just have to have the answer. My dad already got a new phone lol. Any ideas?
