Hello,
Maybe someone can help..
Samsung s4 i337 32Gb will only show the Samsung logo when turned on and after about 2 seconds nothing, screen blank , ( New Screen ) No lights , though it vibrates when its first turned on,
For what ever reason if I keep messing with it( take batter in and out) , it will boot all the way, Even then after a short time it turns off again, and that's only after a few days of messing with it..
Any ideas ?
on s side note I am a retired computer /electronic engineer and have an idea how these work, I repair them on the side for clients and so forth, but am at a lose with this one, Its my personal and would love to be able to get pics and so forth off it,,
Thank you !!
Is the phone running a stock Samsung rom? Have you tried reflashing a stock rom or performing a factory wipe?

yes it's stock and No have not re flashed the rom , wont stay on long enough for a rom flash or a system wipe..
Maybe a battery problem? This happens regardless of whether the phone is or is not connected to a power source?

The same thing happened to my i337 after I installed one app (soft keys) and reboot. Samsung logo showed up for a second and then went dark.
Went to recovery and wipe /factory reset twice did not work.
Finally, went to download mode and odin the NB1 firmware. That solved the problem.
I was on OK2 bootloader then. I do not know what bootloader you are on.

problem is , it wont stay on long enough in down loader mode, Plus I do have things I would like to save if I can.,
I just may have to try and find another 32Gb main board or a broken screen phone type thing and start over..
If it wont stay on, I'm not how the data could be pulled from the phone. If USB debugging was enabled, adb commands may be useful in recovery mode.

I may end up losing the data, So be it..
Would have been nice to figure out what is going on with this one though..

Hello everyone. I have 2 questions. And thank you in advanced and have a merry xmas!!!!
1. how do I check if my phone is simcard unlocked?
2. If my phone is unlocked regardless of how it's unlocked will doing a boot loader reset (holding the power, volume up and home buttons) relock the phone?

Again, thank you very much!!

borrow another provider sim card from a friend or go to a store and ask if you can use a sim for a few minutes, some stores may help.
if your phone is unlocked, a bootloader reset will not relock your phone.
But if I'm using a tmobile Sim in an att phone doesn't that mean the phone is unlocked?

Yes it does, and that whole 're-locking after updating' or 're-locking after a reset' doesn't happen anymore.
You can wipe data a hundred times from recovery if you want, once the phone is unlocked, it's unlocked. Period.
Hi all,
I'm sure I am still one of many that cannot use XCnathan32's solution to fix their phones. I think the biggest problem is that it is difficult to discern between hardware vs. software being the culprit. If hardware, nothing I do can help. I've wanted to use the solution but when the computer cannot even find the device/recognize it, I cannot even start the solution. Let me explain what my phone is like/ the state the boot loader is in:
Google logo is the only thing to show.
Even when trying to boot from bootloader -> recovery mode, it only goes to the google logo and boot loops from there.
Unfortunately I did not unlock developer options / USB debugging so my bootloader is LOCKED, my computer does not recognize the 6P at all unless in boot loader. It gives a strange description of the device, but does not treat it as a device in the device manager. Even if it does show I cannot update it's driver. It essentially seems like only the bootloader is a device rather than the phone.
I have tried leaving the device to boot in hopes of it miraculously starting and allowing me to go to developer options, this has failed as well.
Would anyone know/ be willing to explain how to proceed from here? I'm sure the options are limited when the device does not even show up on the computer.
Note: I don't know much about TWRP, ADB, SDK etc, its all 2 days new to me.
Thanks for any help!

I got it! Used a blowdryer though. Unfortunately it went back to boot looping even after I did a factory reset. I'm going to apply the fix now that OEM has been unlocked and USB debugging!

I'm currently writing a guide to get to the OEM unlock stage on your thread . Thanks so much for all of your work, my phone is currently booting. Its got the google logo with a unlocked pad lock on the bottom and then it switches to a section with android warnings saying "Device software cant be checked for corruption, please lock the bootloader".
Its actually bootlooping again... I've flashed all the images possible on your downloads part of the thread Not sure if there's another option to take to get rid of the bootlooping.

That's the exact guide I used. I also used his first guide before that one was published by XDA. It almost seems too simple though. I feel like I'm missing something. I flashed the 48B_A4 firmware, then the twrp3_1_1_4Cores.img and reboot. It still boot looped. I then proceeded to flash the other possible imgs to see if they would work. I cant flash the EX kernel since I can't boot into recovery since it just boot loops again.

This will throttle the big cluster of processors making it so the phone can stop boot looping by using only the small clusters.

Format all partition except for internal storage.
1. Flash N2G48B_vendor.img into vendor partition
2. Flash N2G48B_4Cores.img into boot partition
3. Flash purenexus_angler-7.1.2-20170725-OFFICIAL.zip
4. Flash BeansGapps-Full-7.1.x-20170610.zip
5. Flash EX4_1_1_4Cores.zip (Elemental Kernel), step up the core speed one notch on first screen, leave the rest on default.
Reboot.
Waited about 10min on the animation screen (4 dot jumping), eventually phone completed booting

sorry to hijack your thread, can i know the steps that you took to enable oem unlock ?
Because i am in your similar situation, all i can see is the google logo & bootloader is locked (i cannot go to the settings menu because the phone doesnt bootup, i am stuck in the google logo).
If i run the fastboot flashing unlocl it fails (since bootloader is locked)

You need to use a heat gun or hair dryer above the fingerprint sensor. Keep phone at low battery but not empty. 5%

How did you know your battery was at 5%? At the fastboot screen I see that the battery says OK, but not a specific number. Does that battery field change when it gets below "OK"?

Hi there - I ended up having to use a blow dryer to throttle the phone using High heat. I wouldn't recommend it, it wasnt safe and my phone after fixing stopped working in an hour. If your phone isn't working despite following the fix above get a new phone, the pixel 3a seems like a nice new option, good luck!

OK, I don't have a bootloop problem per se, but I changed my battery and now it only goes to the Reboot bootloader screen. The arrow keys don't work to change the menu. Sometimes I can get it to Recovery mode, but neither the power key or arrow keys will work. Once I got it to the Start, but the power key did nothing. ADB devices returns nothing, so even though I installed the Google USB drivers in Android Studio I can't get the computer and the Nexus to talk to each other. I'm ready to try heating the device, but that goes against everything I've ever known about electronic devices. Are you sure? .

Unless you are using the Verizon/AT&T variant (and maybe some other variant too, Google it), all other S5 variants already have their bootloader
unlocked.
That option isn't available for older Sammy phones anyway, so don't worry.

I don't have verzion/AT&T i think, because phone bought in latvia and there are no verision shop, if I correctly understanding that verzion/AT&T is shop/mobile network povider. So, Im sure that oem not unloacked by default, because I tried to install clockworkmod, when I use buttom combinations vol+power, phone load default os.

What is your variant? Most likely G900F I guess. Go to Setting/About Device to check your device's model number.

Congratulations, your device already has an unlocked bootloader. Just ignore the disappearance of that OEM unlock option, flash TWRP then flash whatever ROM you want. Be sure to use the right baseband for your ROM though.

When you go to settings search for oem unlock. Don't scroll down through developer mode. Use the search feature on the top and write oem in the search bar then hit search. this will show if OEM unlock is enabled. If it's not you have to use the Verison AT&T way to root.

That's usually the case. There is an easier way to check anyway. log in to download mode. Press and hold Volume Down, Home and Power buttons, all at the same time. Release the buttons only when the ‘Warning!!’ message appears. Next, press Volume Up button to confirm that you wish to enter Download Mode. The it will state if oem locker is is on or off. By the way the long but easier way to do it its burn back the stock rom but the international version not from any carrier like this one: G900FXXU1ANE2_G900FOXA1ANE2_G900FXXU1ANE2 for UK. Then apply all the updates as normal that must take some time depending on your internet speed. Then you will be able to root using the right file made for the specific version of Marshmallow. See that link: http://techbeasts.com/root-galaxy-s5-android-6-0-1-marshmallow-and-install-twrp-recovery/

So I did this, and released all buttons when I saw the warning sign, then the screen blinked and started saying "ERASING" Is there any coming back from this? It seems I have somehow factory reset the phone (facepalm)
I have a Verizon version Galaxy S5 all stock running 6.0.1

Anyone get bricked from the last update (I assume January/December security updates). I tried to update my phone yesterday 1/7/2018. My phone basically downloaded everything, told me to restart, loaded into the bootloader 3 times - after i selected normal Boot, and then stopped and charging.
Pretty glad that I had 2 phones.. because I have a video of it bricking in front of my eyes. not sure if I can post links yet.
Any help would be reallly appreciated as I haven't modified anything on it...
Can you still boot into recovery?

This video is the last time I could get the phone to turn on. The only signs of life I (saw) on the phone was the LED light when I tried to charge the phone -
after it ran out of battery.

The screen won't turn on or off. It's like the power button's broken even though it's still pressable. It should have battery though because I've been trying to turn it on with it plugged in.

You will need to side load the OTA.
You cannot unlock the boot loader unless you check OEM unlock in the developer menu.
Or, at least I have not seen it done.

OEM unlocking is ticked off. That's the issue. I've seen in some videos or posts like Chris Paton. Advising to relocate the bootloader after sideloading the beta OTA's... I followed it and now I'm in a soup.
