This happened to me recently. I ended up having to install a custom ROM. Check out cm 10 for something close to stock. Good luck

no idea, it randomly started for me a few months ago one day. I was completely stock, not even rooted or unlocked. I tried everything, but the only thing that eventually worked was installing cyanogenmod.

Recent samsung devices rebooting a/root cf-auto?

I follow a handful of samsung device threads, tab 3, s6, note 5 etc..., and every one of them have had recent issues that cause the phone to have a reboot that occurs a minute or so after booting up that havent been able to fix with reflashing firmwares or anything related.
My note 5 had to be replaced (no biggie) and others are in the process of doing so as well. A possible fix has been posted by one user but im wondering if possibly the cause is from cf autoroot as it appears that everyone or close to that posted having a similar issue mention cf auto rooting prior.
My steps were flash stock lollipop. Flash stock mm. Cf autoroot stock mm and after that my signal bars or area for were gone completely and the phone rebooted within a minute regardless of airplane mode on or anything else i tried. It did not reboot the same while in recovery stock or custom or download mode as those stayed kn as normal.
I know the warnings and such with cf auto root an whatnot but just wanted to make the observation so that if it is the issue it can be acknowledged before more threads appear with this rebooting issue as it is a PITA.

I did do my best to make it grammar friendly but apparently where i put the tabs and spaces for paragraphs only put the tabs and not the spaces so i giveup on future paragraphing efforts

Well there replacing my battery which i doubt will fix it but when i get another phone im staying away from rooting until this problem get solved . I lost alot of stuff on that device also my next phone will have a sd card or I'm not buying it cloud storage with sprint service =failure

I didn't cf auto root and had the unfixable reboot problem.

Me either i did day one when rolled to 6.0.1 but had odin stock since then only odin twrp then flash supersu2.71.zip.
So im not convinced that cfauto did it now mine is working perfect or better lol. The reboot issue did u pull sim card flash stock. i flashed it but still rebooted any rom it rebooted but i think after that i click repartition in odin with stock tar but then re did it stock tar in odin again . i odined the stock tar into pitfile. then i re odin stock tar after that let it die. im not sure how i fixed it but i did.

I also flashed twrp and restored radio and efs back multiple times

Once it worked sucker was booting up in 14 or 15 seconds and has seemed better then ever maybe cuz i lost this bad baby for few days while she rebooted idk good luck though

We all did the usual troubleshooting in all my time with the g1,mytouch,htc hd2,samsung vibrant,htc sensation, htc evo,htc 3d,htc evo 4glte, galaxy nexus, galaxy s2, galaxy s3, galaxy s4 , galaxy s5 ,galaxy note 1,2,3,4,5 nexus 6 , lg optimus,lg g2,lg g3, gflex,glex 2, htc max, nexus 5, i bricked several devices and fixed them all. This note 5 problem takes the cake i wasted to much time trying to fix it before i said enough. The security on every device year by year is getting ridiculous no matter what you do anything can be hacked.

I guess one more thing to my rambling.
It happened right after i restored a back up but i swiped to restore i saw that efs was checked i said nooooo but it was to late. I never touch that for the most part. one other time i restored it in 5.1.1 i took 2 or 3 minutes before signal.

Well i helped another he tried everything it was rebooting on any rom. i suggested let it die well his worked after that
IF CONSTANT REBOOTING FLASH STOCK
LET BATTERY DIE COMPLETELY

I retract my observation about autoroot then and apologize for that. I just got the same issue with this replacement phone after flashing skyhigh 3.4 in twrp. I let it die as others say works and it did work but su was gone so flashed su in twrp and then had the same issue. Let it die and now i am running skyhigh 3.4 with the su i flashed with no issue. Leaves only one possibility, seems as if its not skyhigh, not su or autoroot but could it be twrp?

Im using 3.0.2.0 twrp with the theme options flashed to it if that makes a difference but to be specific and possibly narrow it down.

Can someone down grade twrp and find out

Well several on g920p the s6 have had the problem we got twro 3.0.0-1 build by sac23 works newer ones wont boot. i got the tebooting problem for 2 days right after a efs restore.

Still its unofficial so this is where them problem starts but maybe somebody needs logs while rebooting nonstop

I cant say its twrp for positive, im just saying in my case, i flashed skyhigh 3.4 in twrp. Had the no signal reboot issue. Let it die. Charged and rebooted and was fixed running skyhigh 3.4. Su was gone tho, so i went to twrp and flashed su, got the same issue.
Let it die, charge reboot and su was installed and everything was fine. The only thing that was the same throughout the problems was twrp. At the same time, twrp successfully flashes with no issues most if not all of the time, its just in this case twrp was used for two different flashes and the same issue occured and a die and reboot displayed both flashed objects running successfully so I would have to point to twrp as it couldnt be skyhigh or supersu and those would be the only 3 possibilities in this case.
I had issues installing the twrp 3.0.2.0 from the twrp.me site, it would bootloop to the recovery is not seandroid enforcing until i flashed a recovery that either worked or flashed stock rom, until i came across tdunhams recovery file listed in his moar mm thread linked note 5 recoveries. Its hard to say its twrp because it works for sure, its just a few times where it hasnt there arent many other things it could be.

Can't load firmware on Odin phone bricked

I recently rooted my phone to try and recover some deleted pictures after the phone completely crashed and wouldn't load up , I have tried to install an original firmware using Odin but I keep getting the same message about not being authorized . Am I installing the wrong files or am I not doing something thathat causes it to fail?

Where did you download the firmware? Are you sure you're using the correct version?
Are you on a G930T or a G935T?
I had the same problem on mine before, what solved it was downloading a later version of the firmware, as you can't downgrade just like that.
You can download the latest firmware from Sammbile. (I would link but I have less than 10 posts.
The T stands for T-Mobile, and the 930 is the regular, 935 is the edge. If you're not T-Mobile, you're in the wrong section, but I'm still glad to help once I obtain more information.

Always flash the most recent firmware becasue if you don't remember chances are you can flash an old version and run into issues, so to be safe flash the latest available firmware. Also when you first rooted did you change the CPU governor or run/install anything that could have caused the bootloop in the first place?

You can install this awesome rom to speed things up don't worry it's a stock rom so no Knox trip. The link I will provide also has instructions. So to get started I recommend making a backup of applications with titanium backup which might require the pro so unfortunately you may have to buy a full version( if you don't want to spend money you can patch the app with lucky patcher). And I recommend checking out this rom: http://forum.xda-developers.com/tmo...stockdeodexeddebloatedrom-7-10-t3415952/page1
It is somewhat debloated and has the best speed I've seen yet... Ive been using it for a month now and I love it!

I thought this device is bootloader locked so how would you even put another rom on unless ur using exynos?

I have the SM-G930A and This also happens to me sometimes too, But usually not very often. I can go days or weeks and then randomly on this one game I play when I exit the app the screen is just black, no homescreen and the samsung logo shows. I think its a soft reboot(The Samsung lgo with the "Custom" and unlocked lock icon arent shown). My conclusion would be for some reason the System Server is crashing

Well I have mentioned in my post it's a g 930f which is exynos model.

Best advice would be a full clean Odin flash of stock firmware, bit of a nuke from orbit approach but it tends to fix most things when they break from OTA's etc

Was 920I now 920F should I be concerned?

Hi, I am not for miller with everything and I am concerned about what I did.
I followed instructions to install Android 10 on my S6 and when it failed
I got into a panic and found this download CF-Auto-Root-zeroflte-zerofltexx-smg920f.zip
and not paying attention to 920F I installed it using Odin and my phone worked again
but the screen was inverted to the touch screen and on this forum, I found by typing in a sequence of numbers on the keypad
I inverted the touch screen back to be able to use the phone again.
few days later I tried again...
I then installed TWRP and EvolutionX_4.1.69_zerofltexx-10.0-20200331-0232-OFFICIAL Samsung S6 Firmware
and everything went to plan but I am finding my phone to be slower than before, about a 2 second delay to open things and somethings like
opening the camera can take a long time and sometimes it hangs and I need to close the App and try again & the flash only works if I tap to focus first.
My question is should I change my phone back to 920i or is my phone now working as a 920F perfectly fine?
And if so would anyone know where I can find the CF Root zerofltexx sm-g920i download I need?
I have searched and searched and can only find a full factory firmware of 1.88Gb but the file I used "CF-Auto-Root-zeroflte-zerofltexx-smg920f.zip" is only 33.4Mb
I feel I need to find this 920i download to correct my phone back to how it was. Or like I said should I not be worried about it now being 920F?
Thanks

question here is does it work correctly like this? you cannot fix something that is not broken
---------- Post added at 09:11 PM ---------- Previous post was at 09:03 PM ----------
in all seriousness, those issues sound pretty experience-effecting, if i were you i would grab a version of odin and the latest stock rom for g920I, flash stock and eventually get yourself set up with twrp and a recent rom which works with magisk.
i do not see any need for cf-autoroot anywhere in my suggestion, but for the sake of information both cf-autoroot and stock roms should be obtainable on firmware.mobi (and if the download seems to be cruelly slow, this little tool used to be able to get much faster speeds for stock roms but I am not sure if this is still the case anno 2020.)
