[Q] GT-i9505 works but screen is black, no splash

Hi people. I have been running a rooted phone for a while and decided to go back to unrooted recently. I decided I would like to use the barclays app and apply the new updates that samsung rolled out recently. However when I flashed the stock firmware I found that the screen no longer worked. The phone seemed to boot up and play the samsung startup jingle but no splash logo. just a black screen. To test I decided to call it and the call came through ok and answered with the home button, speech all functional???!! Just no screen ... completely black??? Would this likely be a fault with the firmware or is it just uncanny timing with a faulty screen??? confused and wondered if anyone else has come across this before I go but a new screen. I downloaded the firmware from hotfile "I9505XXUDMH8_I9505OXXDMHA_I9505XXUDMH8_HOME"
thanks in advance

i would say to stay away from new firmwares at this time....you are stuck in the locked bootloader.
can you boot in recovery or odin modes and see the screen?
wipe data and cache and reflash the MH8 then do the wipe. see if that works
can not determine if it is a HW or SW issue.
if you want to use app that doesnt require root like Barcley and you are rooted, you can hide the root with some available app.

It seems I am able to get the device into download mode, although nothing comes on the screen. I just have to do the procedure blind. No matter what I do nothing comes up. It also seems I can only get the phone to read the internal memory through USB once a flash procedure has completed. It seems to force a boot up but when I try to restart manually it does nothing but vibrate and only seems to be able to put into download mode while blind. I find it very unusual that the screen should suddenly stop working the moment I try and flash the standard firmware. Getting worried now. nothing seems to work

Can anyone help here??? I have tried flashing several times. Just vibrates and does nothing. I can get it into download mode but I don't get any warning screen up. I just go through the button combo's blind and it manages to get into communication with a odin com port. I have tried doing a PIT download. What I was then finding is that the phone can bring up a recovery screen with option to reset, I reset but the phone will just be a black screen and play the samsung start jingle without the splash screen. It then seems to boot and receive notifications with a totally black screen. completely unresponsive.

If you can't see a splash screen or even recovery and download mode screens, then I'd say its a hw issue and no ROM is going to fix it, because those mentioned things are not even tied to the ROM.
Your screen has broken some how, it could be as simple as a flexi connector falling out or as bad as your screen being totally gone.
Sent from my GT-I9505 using xda app-developers app

It doesn't look like hardware problem
i am facing exactly similar situation with a 9505, i tested LCD with another of my 9505, and LCD is ok
is just happened after an Odin flash of stock firmware.

[Q] Back and Multitasking buttons stopped working

I was uninstalling some apps to get ready to back up and flash my phone because my microphone volume was stuck at minimum and no one could hear me. After rebooting my back and multitask (menu) button won't light up or respond. This has happened to me before occasionally. I could fix it by powering the screen off and back on. I believe I read somewhere it had something to do with xposed.
I tried flashing using MOP and my buttons didn't come back so I loaded a TWRP, wiped all partitions, rebooted in download mode and flashed with regular ODIN. Still can't get the buttons to function. Home button works just fine, though.
I tried finding a solution to this but I can't seem to find one. I had the same issue intermittently on my Galaxy S4 but I fixed it by wiping the partitions and reflashing. G900R4 USC variant.

So I went into stock recovery and did a factory reset. It was already as wiped as it could possibly get afaik but I thought I'd try just to see. My buttons lit up in stock recovery so I knew they were getting power. I did a factory reset and low and behold upon reboot my buttons came back.
Did I fix it or is there a circuit starting to fail on my phone and it was just luck? I'm curious.

No sound

After i installed stock firmware there is absolutelly no sound on my sgs4 what's funny is that there is a boot sound (one that plays with samsung logo when booting) but as soon as i get into system boom no sound at all no matter what i click with/without earphones basically nothing
this is on stock not rooted sgs4 firmware
And also when i try to increase/decrease sound via hardware key or in settings phone freezes or crashes any ideas ?

S4 bootloops on every rom, even after Odin stock flash.

Hello, I am having an issue with my S4.
I was having random reboot issues and my rom was quite old (omega 30 or something) so I decided to update my phone. I flashed stock from odin, then installed TWRP again and tried flashing roms. Roms previously would boot up to the point where I would setup android and then reboot. Now my phone seems to reboot almost directly after the "Samsung Galaxy S4" logo. Some roms have let me boot into the android setup but once the Mobile Network seems to try to connect, the phone reboots right away.
I have tried flashing 3 different stock roms thru ODIN and they all have the same issue. I have tried clearing cache/data in recovery but it hasnt helped.
Does anyone have any suggestions or advice? Thanks!

Might be a power button issue. A friend had a similar problem. The phone would boot and work for some time and then turn off.
At some point it just wouldn't turn on anymore.
It was the power button.

Thank for your reply!
Just curious, if it was the power button, wouldnt my phone also restart in recovery and in download mode? In both of those modes, there is no issue. I'm worried that I flashed a modem incorrectly some time in the past and that could be casuing me issues. If the stock rom passed in odin, shouldnt the modem be working correctly?

Stock roms have modems and bootloaders included. So it must be something else.

It's very odd. I have no problems getting into recovery or download mode, but absolutely anything I flash will not boot with any reliability and not for more than a few seconds. I was able to flash Omega 42.1 and that worked for about 30 minutes yesterday and then began bootlooping as well.
I have no ideas.

I hate when people solve their problems and don't follow up on their own threads so here I am to post my solution.
Turns out my battery was slightly swollen and causing the battery to disconnect and make the phone restart. I noticed this after a bunch of various testing with the phone plugged in and unplugged. The phone would work fine plugged in but within a minute of being unplugged it would turn off or reboot.
I purchased a new battery and have had no problems at all since, everything works great. When I compare my swollen battery to the new battery, you can see it is slightly swollen but hardly noticeable if they are not side by side.
Anyway, for anyone reading this thread in future, my solution was to replace the battery which had swollen.

Volume down suddenly broken. Stuck in safe mode

Alright.
So yesterday i was just cassualy using my phone, when suddenly my volume down button started to act weird.
It kept pushing itself and raise or lower the volume. Since i didnt update my phone in a while, i figured it might be a software issue.
So i installed the latest update, and suddenly my phone booted in safe mode. Tried to reboot, no luck. Now my volume down key is unresponsive... I opened the phone up and cleaned the ports, but still no luck...
Looks like the key is dead. Now i am rooted and have twrp installed.
What are my options here?
Can i install an android 9 rom, maybe they wont boot into safe mode, i'm not sure?
I do still have warranty, so i could try my luck with relocking the phone and sending it back, but i also already opened it to look at the volume keys.
Do you guys have any ideas on how to handle this?
