Hi guys. I've checked everywhere for an answer but to no avail. I have a rooted S5 and using RomToolbox I have been removing unwanted bloatware. Somehow, 3 times now, I have inadvertantly caused an error with the Ultra Power Saving Mode. When I enter UPSM I get a blank screen and cannot exit out of it. Tried restarting, no go. Tried Safe mode, no go either. I am using Dodol launcher and so have most likely removed or frozen Touchwiz home. Could this be the issue. I don't want to try it again just in case, but if anybody could shed some light that would be great! What process or causes UPSM to crash??
Thanks!
Galaxy S5 SMG900I
Philz Recovery
Build - KOT49H
Original Telstra Firmware from Sammobile - G900IDVU1ANE1
Android 4.4.2
I was having the same issue with UPSM. Every time I turned it on I would get a black screen, and I couldn't get out of it without doing a hard reset of the phone. After some experimenting I discovered that UPSM relies on another system app called "S Launcher". If you have either frozen or uninstalled it then UPSM will not work properly, and you'll get the dreaded black screen.
Hope this helps.

Hi, I have a black screen on my s5 also.
It did start after I had the phone in power saving mode (not ultra PSM)
It was not instant, I had some freezes to black first. I also had that happening before I was using PSM. I did an Odin back to stock but no luck.
My question is, if I froze an app or service and it created my issue would flashing back to stock fix that? I would have thought it would but idk.
Thanks.
For the record:
The at$t service center reflashed my phone and the screen works again.
IDK why me flashing stock with odin did not work.

In advance, I normally try to fix problems myself thus I dont post much, so I'm sorry if this is in the wrong area. I have already spent about three hours researching and trying to figure this out.
I've gotten sick of the loads of Verizon bloatware slowing down my phone, so I finally pulled the trigger to try safestrap. I'm using the ME7 build so that was the only option.
Safestrap installed without a problem. I flashed Hyperdrive successfully, but the ME7 modules available here would fail to flash even after I checked the MD5. I flashed from another source here successfully.
After all of this, when I boot the phone into that module, it will go to a black screen after the "safestrap enabled" logo. After about a minute, the phone will vibrate, show the Samsung logo, and then go into ODIN download mode.
The only thing I can do now is hold the volume down during start up. This loads a warning about how installing a custom OS will catch your phone on fire with a continue option (which results in the ODIN block), or a Cancel option (that restarts the phone and shows the safestrap logo before going to the black screen etc.) From this I can change the boot default to the stock OS if I choose, but I still cant use Hyperdrive. I have already tried deleting the ROM slot and starting over, but that didnt help.
Thank you so much for the help!
Edit: I tried bonestock and just got a black screen.
Edit 2: I also tried google edition and it would go to a black screen, restart, and loop again.
I was checking Facebook when suddenly the phone restarted, but it got stuck at the first boot logo over and over...then i tried several steps to figure out what's going on.
*First I took the battery out, leaved the phone without it for about 5hrs, then I put it back and no luck... (The SD card was also removed.)
*Later I tried with a different battery and no luck, the phone keeps restarting over and over...
*Tried entering in Download mode and nothing works, the phone does not respond, and then it restarts...
*Tried doing a hard reset, but the phone does not respond to (vol up + home + power)
*Changed the SD card with a new one, nothing.
*The battery is not swallowed.
*The device was rooted and running Omega ROM V17 Android 4.3 (rooted it in December and had no problem).
WTH is going on?, if at least i could use download mode to fix it
(another thing that looks strange to me is that as soon as I put the battery on the phone, the device turns on intermediately and I think it's not normal because the device does nothing until the user turns it on.)
Please any help, this issue is over my head.
Thank you so much.
Download mode and recovery is available??
It can be 2 things:
- You have a faulty battery.
- You have damaged hardware.
No flash is going to help you. It's just bad luck.
Probably your power button was broken and stucked. If you still have warranty, send it to repair in samsung service center. This used to happen to my i9500 once.

I just got this phone alittle over a month ago. Today at work, my phone randomly shut down and started continuously restarting. The phone will vibrate and boot the logo, then turn into a black screen, vibrate again, and restart. I had not modified my device at all. Just downloaded your typical apps like anyone else. I already tried taking out the battery and letting it sit and booting in recovery mode and wiping the cache and restoring to factory settings. I also tried to use odin to flash what i think is my firmware onto the device. I wasn't able to figure out the firmware of the device before I did it so i sort of guessed based on the model. Though all i did for this is download what i thought was the firmware, put it in odin3.4, entered download mode and plugged my device in and let it download. I didnt do any rooting or enable debugging/disable debugging before i used odin. Did I miss a step? Does anyone have any suggestions of something I else do. I am so confused on how this happened to my phone!
I have been having a problem with my note 4. When ever the phone is powered down and powered back up it reboots normally. I see my lock screen and everything is fine. The problem is when the phone locks either by the power button or just by screen time out. It stays a black screen even though i can swipe my my finger and hear it being unlocked. They only way to fix it is to take the battery out and reboot it then everything is good until i lock it again. Any help would be appreciated thank you.
Sorry me again just wanted to ask another question. I rooted my note 4 after this problem started happening. I used cf-auto root so from what information i have seen im still running stock recovery justed rooted. I was wondering can i flash a Samsung software upgrade without any problems. My problem with the black screen started after an software update so i wondering if i could flash and reinstall the update to see if that fixes my problem. Once again thanks in advance for your help im just trying to save my phone and hoping its not a hardware issue.
Hi,
After a LineageOS update, my Samsung S5 (G900F) was working and suddenly shouted down. I tried to restart it but it was booting in loop (always without passing through the first Samsung Galaxy S5 logo). As I wasn't being able to restart it I tried to fix it by installing the stock rom through Odin. It installed successfully and the phone rebooted with images in the screen. If I touch the phone I can hear the touch working and volume also works but I don't have image, not even while booting the phone.
Now, the only way I have to see image (in the download mode only) is to take off the battery for a few minutes and then restart the phone while pressing the download mode buttons.
I tried several times to install the stock rom through odin but the same thing happens everytime so I am still without image.
Any suggestions?
Thank you. :good:
