Bootloop after activating ultra saving mode (having touchwiz disabled) - Galaxy S6 Q&A, Help & Troubleshooting

Hi there,
On Saturday I tried to get my phone in the ultra battery saving mode. But after activating it, it told me, that the launcher can't be loaded. Since I used a Samsung package disabler to disable not needed apps (including TouchWiz) I think that caused the issue.
Then I tried turn off the save mode, but since the launcher did not load, I was not able to do so.
So I rebooted my phone. As it turned on again, it only loaded the Samsung logo and pulse and nothing more. I tried to reboot it very often, but still no result. I mean the phone still vibrates after some seconds and the hardware buttons blinks (the sign, that the boot is completed), but the Samsung logo is still there.
I also tried to boot it into save mode, but same result.
Wiping the cache partition in the recovery mode, did help at all.
Now I want to know, if there is any other way, how I can get my phone working again. It's not rooted or any customization made (except for the package disabler).
Or at least a way to backup my phone, so I can do a factory reset without loosing my data.
Thanks in advance!

Only saw this post after I submitted mine.
I'm having the exact same issues as you. Enabled UPSM whilst using Nova launcher. Then the device went in to a boot loop.

Ultra Power Saving Mode - unusable phone

Hey guys-
Was on a long international flight yesterday and decided to put my (unrooted) Galaxy S6 into "ultra power saving" mode for the first time. It was a horrible mistake and I'm not sure how to undo it!
The first issue it had was that it said Ultra Power Saving mode doesn't support the use of themes, so it was reverting to the default theme (I use Material Black).
After a long time of saying it was reverting to the default theme, I'm not sure if it worked - it ended up in the state that it is currently in: if I turn the phone on, the screen is just black - it has the status bar at the top of the screen, but just a blank black screen below it. It does not look like images I've seen on other websites for what Ultra Power Saving mode is supposed to look like (no icons on the screen, no "More" at the top right). If I go to settings by dragging from the top of the screen and hitting the settings button, I get a very limited set of settings: WiFi, Bluetooth, Airplane Mode, Mobile Networks, Location, Sound, and Brightness - nothing that enables me to turn off Ultra Power Saving mode.
I am afraid to reboot the device, because when I did that yesterday, I had major issues. My device is encrypted, and I think this mode doesn't play nicely with encryption; when I rebooted the device, I was asked to sign in to unlock the encryption (as normal), but then the encryption booting screen (an unlock symbol with a circle around it) just idled indefinitely - for an hour or two. I couldn't do anything to get the phone to actually boot. Eventually, many hours later, rebooting the phone and logging in allowed it to boot to the state I described above; I don't know what went differently that time.
I tried various key combinations on restart, one of which seemed to result in the device trying to boot to Safe Mode (it said safe mode in the bottom left corner when asking me to sign in to device encryption), but ended up leaving me in the exact same place - the extremely limited Ultra Power Saving mode black screen I described above.
Anyway - is there anything I can try to get my phone out of Ultra Power Saving mode and back to normal? It is unusable right now and I can't figure out how to get it back. Would like to avoid a factory reset if possible (because I'm overseas with ****ty internet, and don't have access to my office to get it re-set up with enterprise mail etc.).
If I have to factory reset the device - I'm not even sure how to do it from this current UPSM state, so any tips there would be helpful too.
Thanks a ton in advance for the help guys
Go to download mode, reflash original rom with odin. You need your rom file from sammobile or samsung-updates or xda and odin 3.
Sorry, I am no power user although I am not totally tech incompetent. Can you tell me in a little more detail what your instructions mean? It sounds like it is basically a total reset of the OS; is that right? Any implications for my warranty? Any alternatives?
If you had package disabler and disabled any of the packages required to run ultra power saving mode, you get symptoms like this.
com.sec.android.emergencylauncher is one package amongst many.
I have honestly only heard of factory resetting working.

Galaxy S5, can not get out of Ultra Power Save Mode, constantly reboots

I've posted a similar message on another forum but we haven't been able to get close to solving this yet. A family member has an unrooted S5 which has had issues with Android updates in the past which were solved by using Kies. Since that time there have been no major issues. There has never been any physical damage to the phone. It is out of warranty but slightly half way through the 2 year contract with our carrier.
We put the phone on Ultra Power Save Mode 3 weeks ago Right away it shut down and kept restarting in Ultra Power Save Mode. There is very limited functionality (grey screen with most apps not available) in Ultra Power Save Mode and no way to remove this setting. The shutdown cycle is less than a minute after it starts.
It is important for me to try to protect the data on the phone so I have not done a factory reset yet. I've tried Safe Mode, Recovery Mode, clearing the cache, a soft reset, removing the battery, removing the SIM card, charging the battery fully, fully discharging the battery and none of this makes any difference. It was recommended that I reflash with the stock firmware and I did that through ODIN. The firmware installed, apps optimized, and then the problem started again. At no point has a computer recognized the phone so Kies and SmartSwitch have not worked. I now just keep the battery out so that the phone powers down and doesn't keep cycling.
Forums, including this site, have suggested various solutions. One suggestion was to reboot to a bootloader and type "am enable com.sec.android.emergencylauncher" but I can't find a way to do this. Another was to drag the Google app to the top and click "More" and "Delete updates". There was some suggestiong involving Google Now that I couldn't understand. I just have TouchWiz installed. There were other similar suggested solutions but I can't do any of those as I don't think I have installed the apps that were suggested.
Eventually I think this will lead to a hard brick but I'd like to get the data off before it happens. Thanks for any suggestions.
Try installing a custom recovery make a nandroid, then factory reset. For sure something is corrupted. There are too many apps to restore files after a factory reset.

Can't find my OPO on ADB, also reboot loop on lock screen, help please?

Hey guys, I'm having a problem on my OPO after updating to Android 6.x.x (don't know the exact version, just the newest available update). I've been using 4.4.4. for a long time because of the superior battery life, but I was forced to update because my google play services started to crash every ten seconds. Anyway, after a couple days of going crazy with the insane battery drain (the phone was very hot during screen on, unlike in 4.4.4). I thought something was using power, so I went crazy with the privacy settings and privacy locked Google Play Services and a couple other apps, it asked me if it could access my contacts or something , I selected no and never ask again. The phone immediately stopped producing heat at the back and I browsed internet a couple minutes and thought everything was finally great. After this I turned the screen off. When I turned the screen on, it let me enter my lock pattern, but straight after that when it's supposed to open my home screen, it freezes and reboots after 5 to 10 seconds. The reboot loop is endless from this point forward, now it even crashes straight after I enter my SIM PIN code and goes into a reboot loop.
I had updated to 5.x.x before when it first came out, but had the same insane battery drain problem there so I went back to 4.4.4. So I have TWRP installed (I used it the last time when I went back to 4.4.4 from 5.x.x, so it should be there still?). I can access fastboot (volume up + power) and cyanogen recovery (volume down + power). I tried following this guide http://www.androidpolice.com/2014/1...den-death-bug-results-neverending-boot-loops/ , but when I run the command 'adb devices' , while my OPO is connected via USB in either fastboot or recovery, my PC won't recognize my phone (OPO doesn't show up either in device manager) and just gives me 'error: no devices found'. What should I do? I haven't tried factory reset in the the Cyanogen recovery, because I read somewhere that it probably wouldn't help and I'd lose all my data. However I'm willing to try this if there are no other options. Thanks for any input you guys might have. I can also post a video if needed to troubleshoot and demonstrate the problem.

Did you wipe your data partition when you updated frowm 4.4 to 6.0? Its most likely that all the apps are crashing due to incompatible data files.
I've once had the same problem and i managed to fix it with deleting data for every crashing app, so this might be an option.
Otherwise you might fix your phone by factory reseting from recovery.

S7 crashes on boot. No response to input. Drain to 0% to power on again.

It started a few days ago, I was testing a cardboard/gear vr unity game and the screen would turn black but the buttons were responsive and I could get it to hard reboot or make it come back again after plugging it back into the gear. I looked around but couldn't find anything that resembles my issue.
Now as soon as it boots it goes into a black screen after samsung and carrier logos show, i sometimes get a glimpse of the lock screen and respond to some input.
The phone is still on, I can feel the battery warm.
-No response to any input. Not even pwr+vol down.
-PC won't detect it when plugged.
-No lights on charging.
-I need to let it fully drain for it to shut down and try anything again.
-Did a factory reset from recovery mode, wipe cache. Still the same.
-No root.
-There was an update that may have installed overnight but can't confirm because can't access system info.
EDIT: New find! when booting to recovery, goes into "Installing Update" and then "No command".
Any thoughts??
Is there some pc software that i can use to try to reinstall firmware? Something like SEUS for sony phones back in the day?
Is odin safe or should i look into a samsung official tool? I've never used odin so i'm not sure of it's capabilities (this is my first sammy phone, I had it to get to test gear vr apps)
Sorry for the long post but wanted to get all the info out there.
Thanks!
Can you enter "Download Mode"? (By rebooting and pressing HOME + VOLUME DOWN)
If yes, I suggest that you try, as you suggested, reinstalling your firmware.
You will have to know your carrier, or specific phone model (G930X, where X represents carrier letter (Example: T for T-Mobile) )
Modified Odin (by PrinceComsy): https://androidfilehost.com/?fid=24591023225177749
Then I suggest downloading firmware from https://SamsungBay.com as all other sources restrict download speed (So it takes a minimum of 13 hours).
https://samsungbay.com/download-firmware/?device=&model=sm-G930&firmware=
Once you have Odin and Firmware, load the correct files.
(AP_G930X), (BL_G930X), (CP_G930X), and (CSC_G930X) into Odin.
Power off phone, and boot into download mode (Pressing HOME + VOLUME DOWN)
N.B/ You will lose all your phone data, sadly, but it seems you've already wiped it.

Stuck in bootloop. Please help!!!!!

Hi everyone! I really appreciate it if you can help! I connected my ZTE AXON Pro phone to the computer and deleted some folders and files in my phone through Android File Transfer, and the phone worked normally after I deleted the files. But the next day when I turned it on, it was stuck at the "AXON" logo screen. I went to two repair shops. One could do nothing about it and suggested me to contact a data recovery company since I need the data in my phone. The other shop thought my phone was fairly old (I started to use it in 2017) and they suspected that the battery had gone bad and wasn't supplying enough voltage for a full boot cycle. They ordered a new battery and tried floating it plugged in, but the phone still wouldn't boot. They said the motherboard was also getting very hot approximately where the power supply chip would be. They tried to charge the new battery but nothing brought the phone to life, so they diagnosed it as a power supply chip failure. They couldn't fix it. But I think the problem is caused by me deleting the files that affect the system. After that I put the phone in recovery mode and wiped cache partition, but it still wouldn't fully boot up and it's stuck in bootloop: Now when I turn it on it's stuck at the "AXON" logo screen for a few minutes and then "Android is starting...Optimizing app 1 of 3.""Android is starting Optimizing app 2 of 3.""Android is starting Optimizing app 3 of 3." show up, and then "Android is starting apps." shows up. Then it restarts and stucks at the "AXON" logo screen, and repeats the loop over and over again until the battery is completely drained.
I have some very important app data in the internal storage and I can't afford to lose it. Does anyone know how to fix the bootloop without losing data? Thanks a lot!!!!!
Boot this Androd 5.1 based phone into "Safe Mode":
Safe mode can help you investigate and find problem apps if optimizing app 1 of 1 ... issue is caused by unsuitable or broken apps. You can stop Android optimizing apps by booting the device in Safe mode.

Thank you for replying! I just tried to boot it into safe mode, but it didn't work. When I saw the ZTE logo on the screen I quickly pressed volume down and held it for about one minute or longer, but the phone was still stuck at the "AXON" logo screen and started the bootloop. It wouldn't load in safe mode. I've tried a few times, but it still doesn't work.
