Can I downgrade to 5.1.1 from 6.0.1? - Galaxy S6 Edge+ Q&A, Help & Troubleshooting

Hi..
My s6 edge plus model is SM-G928C (Saudi Arabia). I saw the Iraq version of MM and flashed it through Odin. Everything runs fine except the following:
1. Battery draining faster,
2. Whenever I shut down or reboot the phone, it shows "Android is installing, Optimising Apps 2 of 2",
3.USB Debugging is greyed out.
I tried to reflash the firmware but I still get the problem. Hard resetted it 2 times, no luck. My knox counter is still 0x0. What should I do? Can I downgrade to 5.1.1 again? Coz the battery was much better in it than MM.

Yes you can ?
/CK

Yes you can and I'll tell you how.
I also have the 928C from UAE. What you must do is, flash the 5.1.1 stock firmware via odin. Uncheck auto-reboot. If it automatically rebooted, you will get a bootloop again and again. So the phone doesn't automatically leave, uncheck auto-reboot. Then when you're inside Download/Odin mode and you finished flashing original firmware, manually restart the phone yourself into stock recovery and do the full wipe of everything. It will reinstall the firmware from fresh and you won't get bootloop. This is what I did. And it worked. It took me a few hours to figure this out because I kept getting bootloop after flashing when the simple solution was to go into stock recovery and just factory reset all data...Not sure why this works but it does. Good luck

So that means I don't have to mess with the bootloader version or stuff? Cos I really don't know all that stuff. Thanks for the reply.
Did you notice the battery drain in MM? And is that why you went back to 5.1.1? Please help me on this.

I always preferred using TouchWiz. It's not too bad. On mm I didn't have battery drain because I had root and it fixed the deep sleep issue which disallows the phone to power down during screen off. I came back to lollipop because on mm TouchWiz lagged. With lollipop I'm using the arter97 kernel. And it's blazing fast. So I'll have to wait for arter kernel for mm once it's stabled and try that on mm. I never had to mess with a bootloader. I thought I was going to have to after getting boot loop. But the simple fix was to enter recovery right after Odin. And factory reset

Ok. So I flashed the firmware back, but I dont know how to go directly to recovery mode from Download mode. How to do that?
I tried by exiting Download by pressing Volume down and power, and as it rebooted, I quickly help volume up, home and power button. But still it didnt go in recovery mode. Can you please help me how?

The same buttons that you press to enter Odin/Download mode, hold again when you finish flashing. For maybe 10 seconds. AS SOON as the screen turns off, move and hold the buttons for recovery mode. I can't remember which is which, I get the combination for recovery mode and odin confused. Remember. AS SOON as Odin mode exits and screen turns black, release all buttons and then hold the recovery mode buttons until the Galaxy s6 + logo appears, wait a few seconds. Then release and you should be in recovery.

No problem bro. And if you have any issues with deep sleep (Where the phone doesn't shut off CPU cores during screen off) then you can download CPU spy and if Deep Sleep is 0, then you have the deep sleep issue and will cause battery drain. And the phone gets hot in your pocket. IF you have this problem. Then flash Arter97 kernel version 11.0

how can i comeback to 5.1.1

Just downloaded CPU spy and it shows deep sleep as 2%. Meaning no problem? I mean the phone has just flashed.
Update: Deep sleep has raised to 43% after an hour and a half. That means good?

For Arter97 kernel do I have to root the phone? Cos I don't like that.

Yea, you have to flash philz recovery via odin. Then inside philz recovery flash kernel then root.

Remember to hold the same buttons you use to enter download mode, but this time hold it for like 10 seconds to escape. That's what I did.

I got stuck on bootloop too but marshmallow completely messed up my phone:
The 6.0.1 BTU MM update has royally messed up my phone.
It was ok at first but my Google contacts wouldnt sync constantly throughout the day so i cleared the data and it kept going crazy rebooting crashing every 2 mins even not letting me factory reset from recovery it would boot a bit then crash.
I did it OTA then used smart switch desktop to reload the firmare to have a clean install still same problem would freeze and crash after couple mins or secs of use.
Does anyone know what might have happened?
I was up all night tryna fix it resorting to flashing with odin the last lollipop OJ2 that i was using before but it still was crashing and rebooting i tried clearing cache partition and master reset several times while still on marshmallow and also with lolilop it would crash and not even let me factory reset as it would freeze when i try to use volume down key to click yes to clear everything.
It was working fine before on lollipop now even tho i am back on it it isnt the same randomly reboots. When i get to the start up screen aftrr factory reset it crashes halfway through adding my wifi etc unless i do it quickly i try clearing cache partition after flashing lollipop but it gets stuck on bootloop which i cant clear except pressing vol down and power button for 20 secs then it freezes.
I finally i hope have some stability in the firmware but every time i go to android recocrry to clear cache partition it crashes while booting up and restarts again then freezes. What the hell is going on?
I thought clearing cache partition master reset etc should restore it to a clean firmware.
What is causing this crashing? Traces of marshmallow should be cleared once odin flashes over lollipop and also factory reset clear cache partition yet i still have this issue.

Do the following things to get rid of this bootloop: go to sammobile.com and download the Iraqi firmware G928CXXU2BPB8_G928COJV2BPB7_MID MM, put your device into download mode (sure you know how to?), using Odin3_v3.10.7 flash it and report...
Sent From my SM-G928F via Tapa

When I was dabbling with firmware from another country/model I upgraded to 6.01, I then hastily downgraded back. My OP is here : http://forum.xda-developers.com/showpost.php?p=65588641&postcount=167
Hope it helps.

[Q] i9500 rebooting into s4 logo even download mode is rebooting

my galaxy s4 is always boot looping into Samsung galaxy s4 screen. only the download mode screen appears but it reboots again after 5 seconds and keeps on rebooting . any help ?
Do you run with stock or custom recovery? Have you tried to (re-)flash a custom recovery (CWM highly recommended)?

Hm, if I understand you correctly, you can boot into download mode but it just lasts a couple of seconds before it reboots on its own, right? You cannot boot into recovery as the screen simply stays black. Can you boot successfully into /system or does it bootloop as well?
Sounds like a hardbrick to me, the only thing I can think of before sending your phone in for repair is to pull out the battery for 1 hour or so, reinsert it and boot directly into download mode and see if it stays there. If it does, flash a custom recovery using Odin and check whether you can boot into it afterwards.

I'm, I was actually, on stock everything, rom, kernel and recovery
30 68336826
OK so I left my phone without a battery in it for the afternoon, just got back home and gave it a try.
It booted. No idea why or what actually went wrong.
Lets hope it doesn't happen again!
OK, So the point that the phone just start booting just the moment the battery is inserted got me thinking
IS IT THE POWER SWITCH?
and indeed it's, the power switch is stuck on, although I can feel the click when I push, still, seems like something is wrong with it
so I tried to suck it out, hit the phone softly few times while the power switch is facing the ground
inserted the battery, aaaand, it didn't start booting, pressed the power softly, and horaaaaay, it's working
Had the same issue and indeed I knocked the power button several times and it worked very well. Thank you! You saved my day

I have similar problem... and identified its power button.
How i identified is as phone switched on i hold menu button and volume down button together and
it booted in download mode, for download mode you have to keep pressing power button, volume
down button and menu button but it went without pressing power button.. so i assume that its power
button.
Try it... hope will identify your problem
same Problem
Hello!
I have the same problem, and disassemble the cell and saw that the button will operate properly .
Someone has managed to get out of this problem?
thanks a lot... i was facing same problem... i hit ma phn near power switch...again n again... it worked... love u xda
whoa, I just got this problem recently, because some of bezel around my phone has cracked, then I try to glue it roughly.
at the other hand, I tried to install new kernel. I tought that kernel make my phone bricked. then I found this thread. so I open my case. and found my glue sticked to the power button, remove it and. voilaaaa~
thank you XDA. you never cease to amaze me. lol

[Q] GS4 problems

so my sister has an att galaxy s4. And she started having this problem with it only booting into download or factory mode. So after two days of struggling I finally got it to boot normally only after doing the download mode button combo, and selecting for it to cancel the boot. Then it kept on doing it after every boot so I thought i would flash the stock firmware from odin. This did not work as well and I kept getting "fail". Now I did an over the air update and as far as I can tell, it is still having the issue. Also I cannot get into recovery with the button combo to delete the cache. Thanks for the support and any help would be greatly appreciated as I do not know where to go with this.

Update: after the update it has now started to boot successfully without the extra steps, will report here again if it reoccurs.
problem still persisting
Well now the phone can boot into the normal stock Rom just fine, only after the previous method is done. Phone does not stay off after powering down and just reboots automatically into download mode. Thanks for any help guys, no idea what to do now.
Kind of sounds like some of the buttons are sticking. Maybe the power button (why it won't stay off) and/or the volume button rocker switch. You could try repeatedly pressing to clear whatever is making it stick. Also you can open the phone up and use a can of air to clean out the buttons. The only thing I can think of that may be causing this issue

Hang on second boot usually means a corrupt data partition or bad app.
After factory reset leave your tablet alone for 15mins. It should boot after that.

Go to recovery and factory reset again then immediately boot to Download mode and flash the correct firmware with odin.
Make sure there are no errors when flashing and it flashes successfully.
Reboot and wait at least 10mins.

It is not broken @pitho. I have been in this situation. The problem is occurring because Samsung is such a heavily modded rom, it takes a long time to load and just as @ashyx said, because of a bad app. Some apps are aimed for Vanilla Android, but the developer does not restrict the app only for Vanilla devices but makes it universal. So, in order to get out, download the correct firmware from Updato.com
Press on the OS Updates in the website and you type in the device's name and the current build and what kind of version you want. (Ex: If you have Marshmallow, and your device had Lollipop before, you could degrade your firmware)
Download Odin (Just search it up on Google and you should find a download link)
Plug in your device to the PC after it is in Download Mode (Volume Down + Power Button + Home Button)
On Odin, it should say Device added!
Press AP slot and find the firmware (.tar.md5 or just .tar) you downloaded from Updato.com and select it.
Press Start on the bottom of the application and it should start. It takes about 2 minutes or longer to finish flashing.
There! You just restored your device! It will take a few minutes for the device to boot up and should be installing any additional files that were included in the Official Firmware.
Happy Flashing with ODIN!

Stuck in recovery boot mode, odin doesnt work

Hi, I'm new to everything so please bear with me.
I have a samsung note 3, I just tried to root it with kingoroot, and was successful. I then downloaded clockworkmod recovery. I also downloaded the new darklord rom, and a darklord kernel.
I booted in recover, flashed cache, data, etc (as per darklord instructions), 3 times, flashed ROM, flashed kernel. Then I rebooted. It just rebooted into the 'factory reset' version of samsung galaxy immediately., ie within 2 minutes. So I restarted the phone, this time it started going into a lengthier reboot/install. Again, approx 10 minutes later, back to the stock samsung os.
I rebooted once again, but then the phone just kept rebooted over and over on it's own. I tried the vol down, home and power button to get into odin, pressed vol down to 'cancel', but then back to the reboot loop. Went back to odin, pressed vol up to install, and it stayed stuck on the installing screen for greater than 15 minutes.
What can I do next? Holding the vol up and down button only brings it back to the recovery boot loop again.
edit:
A few things I've tried, with no success, after reading more threads:
Taken battery out for extended period of time (1.5hr) and then retried boot...
restart in 'odin mode' numerous times
vol down + home + power key while in odin mode
hold down these three buttons with battery out, while holding buttons down, insert battery

flashed rom thru odin, said 'pass', rebooted phone, still the 'not seandroid' error, and then switches off, instead of reboot loop. I'm going to try to download a different stock rom -- dunno if that'll do anything... they take so long to download/access...you'd think it would be an easy access repository? A lot of paid download links, or restricted speed download links....
If your stuck on a BL reboot loop, there is a good chance you haven't turned OFF reactivation lock. With any Samsung Rooting adventure, turning off Samsung Reactivation Lock in Security Settings is a fundamental must. If you have forgotten to do this. You can...
A. Start again by reflashing stock firmware with Odin (when you setup your stock rom, just bypass logging in to samsung and you wont need to worry about a reactivation lock being present.
B. http://idlekernel.com Download just the bootloader file for your N9005, flash via BL field in Odin and this will bypass the reboot loop and you will save everything on your phone except your recovery which is easily reflashed back.
What i would do as well is flash a stock rom, when your in odin make sure you have auto reboot untick. Pull the battery for 30 secs and start your phone up then. When your phone restarts with the stock rom, you can update your phone through the regular system update or again go to odin and flash twrp 2.8.7.0 recovery tar file. Make sure all your new files to flash is the correct one for your phone.

thanks everyone -- i downloaded a different firmware upgrade and flashed it through odin -- successfully. I then tried to install the rom again, and similar problem - stuck on the 'samsung logo' screen... for up to 40 minutes.. restarted, same thing.. had to flash through odin again.
NOW the back button doesn't work..... didn't realize being a newb would complicate things so much.. :S
.. didn't realize being a newb would complicate things so much.. :S
Its a question of reading and understanding first .

You Factory Reset .
You make sure its a rom for your model and follow the instructions .
Flash the rom again through recovery .

I9505 bootlooping & not booting

Galaxy S4 I9505
Phone was second hand to me at the start of this year, though had been well looked after, always in a case etc
I flashed it with the newest stock ROM in January this year
I9505XXUHOJ2_I9505BTUHOJ1_I9505XXUHOJ2
& rooted with CF AutoRoot
It has worked fine until about 2 weeks ago, when it randomly shut down. After restarting, it kept bootlooping.
Left it off & charging overnight, & the next morning it booted ok. Managed to use spotify for a few hours.
Then it started bootlooping again, sometimes getting all the way but then crashing after a few minutes.
Managed to boot into recovery & do a 'wipe cache', that didnt fix it.
'Wipe data' didnt fix it
Have flashed the PIT file & ROM (via odin), no errors in odin, done it twice now
wiped cache & data
still wont boot past the white splash screen, only sometimes boots into recovery
(also, only the menu button lights up, not the back button.)
I've checked the power button (clicks & dosnt stick)
Dont think the batteries the issue (charges fine, dosnt get warm, isnt bulging)
What else could stop it booting?
Have you tried booting into safe mode?
Safe mode, from what I read, can be accessed by holding the menu button while the phone boots.
But you should also do some reading about it, in case I'm wrong.
The other idea would be to try a custom ROM.

Can't boot into safe mode
(& having read up on it, it would only not run apps that arn't already in the ROM)
Any suggestions for a custom ROM
& why would it work when the original official one won't?
Well, it's booted far enough to get into android & add a google account, then it bootloops again.
Then after leaving it off for a while, it will boot & let me look at settings etc, then bootloop
however
the menu soft key stays lit all the time after a boot
the top half of the phone, around the camera, gets very warm
Does that indicate it's a hardware issue?
Could it be the battery?
If it's the top half warming up without you doing anything, it's the motherboard.
Boot into recovery and and let it stand by, see if it reboots.

Well, it's booted far enough to get into android & add a google account, then it bootloops again.
Then after leaving it off for a while, it will boot & let me look at settings etc, then bootloop
however
the menu soft key stays lit all the time after a boot
the top half of the phone, around the camera, gets very warm

The battery can't prevent the ROM from booting. It would have to turn off during the boot, which it doesn't. So, by my logic, it isn't the battery.
Try official CM.

I am not able to go into recovery after firmware flash. The recovery bot appears and when the blue loading bar goes to half, the phone reboots and then again boot loop. I just noticed this always happened when i flashed a rom. I was never able to enter recovery on first boot.

Yes it goes normally into download mode. Firmware always flashed without any error. But i noticed I can't enter recovery on first boot to do factory wipe.

Why do you want to do factory wipe after one boot?
Its the only thing i didn't tried till now, my phone crashes and reboots everytime during boot.
