[Q] Possible to unroot device while screen LCD is broken? - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

Hey guys,
Is it possible to unroot a galaxy S4 device without using the device it self? Long story short, I dropped my phone and the LED display broke, so the screen is all black when you turn it on. However, the phone still works (sound/vibration/call). Preferable, I would like to send it back to Samsung to get the LED display fixed...and send it back un-rooted. But other suggestions are well accepted
Edit: I have a galaxy s4 from Fido, Canada

Well you can use Odin to flash back to stock.

Technically they cannot fault you for root because root is not the reason for this failure, but better safe than sorry.

Cracked screen, sending device back to LG, but need to wipe it first, without screen

My screen cracked on my N4 and I am sending to LG to get repaired. I want to wipe the device first, but my screen is unresponsive. I don't have USB debugging enabled, but I can see my N4 directories if I plug the phone into the PC.
Is there anyway to flash images or even power off the device? I can turn the screen on, but the screen won't work. So I can't even power it off or boot into bootloader. Any ideas?
Well, I figured out a way. I remembered I had Cerberus installed with the ability to wipe the phone and SD card remotely, so that is what I did.
If the phone is on/ awake hold the power button for about 15secs. Then boot into recovery, up col and power I believe, then wipe data. Not sure the button combo to do that though. Probably up then down x 3 then power. But don't quote me. I don't have my N4 yet so if someone can try it and record the exact button steps that would be great.
This is assuming you don't have a custom ROM or recovery.

So it wasn't rooted or custom ROM or boot loader unlocked etc?

Also...funny thing is, I had an RMA with google already because I had yellow tinting on the screen when it got warm. The RMA arrived the same day I cracked the screen. So I called Google and told them and asked if I could just buy the new one and not send my old one back. They said that was fine. So, when the cracked screen gets fixed by LG, I will have an addition N4.
I'll take it for $325! Lol you know,as a helpers bonus...or something

Looking for a new lock screen

Hey everyone,
I'm looking for a lock screen that will give me notifications but also security, I've tried lockerpro and really like it but there is no security with it and having in effect to unlock two screens (if I use my built in security) kinda defeats the object of having an alternative lock screen.
Can anyone help.
Many thanks.
Azel

You can use any 3rd party lockscreen with the stock one. The stock one has an option to have slide + security or just security. So you turn off slide on stock and have slide on your replacement screen and security from stock.

Hi, I just picked up my SN-9005 from Australia.
This only happens when downloading or uploading via Wifi.. Camera Zoom FX seems working fine, but stock camera app.
A few peoples are suffering this issues in Australia and want to know if this is global issue.

UK here and I'm pretty sure we have the same problem. Your video file isn't there to be certain but I don't imagine two similar problems like this

nexus 4 doesn't wake up from the power button

I have a problem with my nexus 4
I am using stock 4.4 latest one and I am rooted and using closed fw
The problem is when I wake up I found that the alarm doesn't wake me up and th e phone is like shutting down I think it's freezing on the black screen and I cannot open it from the power button and I have to long press the power button to shutdown it and press it again to power it on and I found a missed alarm I don't know if that from the KitKat or from the root or what actually I didn't had this experience on JB
So if I can solve this just let me know Guy's
thanks

What about a broken power button? I've replaced a bunch of them on sgh-t989, so what if it happened to the n4? I've been using mine ever since it was released in 2012 and there's no issues, but you never know... Just my first thought...
Also, the proximity sensor/headphone jack ribbon cable can be disconnected without affecting the usability of the phone, so i guess he could try doing that, if you say that it might need replacement of it.
Have u got chance to check proximity sensor , as other member suggested just remove sensor n check , it will even work without sensor but u may find your problem

4.4 will not boot with proximity sensor/headphone jack cable disconnected - n4 will not boot past boot logo ...

You would may change display
Fail hardware.
I agree with the friends above.
Definitely hardware failure, that sad.
Happened with my S4 too.
This is definitely a hardware failure.
I went to the service centre and they replaced the screen for free as the mobile was under warranty.
You better hurry up and get it fixed ASAP. :good:
