Auto boot upon receiving power - Samsung Galaxy S8 Questions and Answers

Hopefully I'm not reposting a question already answered but i cannot find it on this S8 Forum. I wish to auto boot into the OS upon plugging in to a charger, I have tried editing the lpm file in /system/bin/ however it doesn't seem to want to work, I had it working however it booted me to the TWRP recovery.
Any thoughts and suggestions would be greatly appreciated.
Samsung S8 SM-G950F
Android 8.0.0

Thanks!

Bump, anyone please

Hard Bricked Galaxy S5 Verizon G900V need img plz

I found a similar situation on a thread from 2015 which i replied to so this post may duplicate that...if so my apologies. I'm a bit distraught over the hard bricked phone in my lap...
In the process of loading a ROM on the wrong partitions through Flashfire i've completely hard bricked my Galaxy S5.
The phone is completely unresponsive--does not power on, won't connect to Odin, and will not enter download or recovery mode. It shows on the device manager on Windows 10 when connected as QHUSB_BULK. From research it appears my only option is to use image creator to create an image on an SD card then try and enter download mode.
I was using a rooted lollipop based (5.0) phone at the time of the issue. I tried an image from a thread from 2015 where someone exhibited almost identical situation and resolved it with an image from 4.4.2. Unfortunately that image did not work for me. Does anyone have a lollipop based image they'd be willing to PM or link for me?
Would really appreciate it. Very bummed on an Easter Sunday with a brick for a phone.

Samsung Galaxy SM-G928X stuck on startup screen!

I have been trawling the internet for literally hours.
This is my final hope before I get really desperate with this device.
I bought a Samsung Galaxy Edge+ online as a demo unit so I could use it as a glorified tablet,
since it was a demo unit it had demo software which I tried to remove using the 5444 password
trick on the retail software to no avail. So I decided to root the phone using Odin and the
SM-G928 F/I/C/K/S software as i couldn't find the particular software for this phone anywhere.
This worked but every time I booted the phone it would give me the 'KERNEL IS NOT SEANDROID ENFORCING'
on the top left of the device which I promptly ignored and continued to use the device, I downloaded
root check which said my device was rooted and then I downloaded system app uninstaller to try remove all the trial
software, which unfortunately didn't work. I then attempted a hard reset, which also didn't work and just
rebooted the device, finally i decided to download Flashify and TWRP recovery to try and delete the trial software
from there. At this point I was just messing around with the phone when I noticed a thread that said i needed
titanium backup to fully delete the software, so i rebooted the phone and it has been stuck on the bootup screen
ever since, I have tried several methods to get it to work including re-flashing the software onto it,
(the SM-G928F one I mean) but i simply cannot find the correct one for my device.
Any help would be greatly appreciated :good::good::good::good:
The device is running 5.1.1
I am not sure of the kernel or anything like that as I am quite noobish.

First thing to do is to get into STOCK recovery and do a "Factory Data Reset"
or you can boot the phone up and go into "Settings>Backup and Reset" and
select "Factory data reset".
After doing that odin flash the proper S6 Edge+ Lollipop 5.1.1 or the new Marshmallow 6.0 firmware.
You can see the exact model of your G928 phone by going into settings and scroll down to "about"
there you will find the specific model of your phone.
Be sure to ONLY odin flash the correct firmware for your phone's model.
Once you do all the above you will no longer see:
'KERNEL IS NOT SEANDROID ENFORCING'
The only reason you see that is because the phone is rooted.
After odin flashing the proper firmware your phone will no longer be rooted
unless you root the phone again.
Good luck,
Have a great day!

I can't boot the phone up, if I could I would, I can't find the software for this particular model, which is aforementioned SM-G928X,
If you could help me with that, I would appreciate it. The phone is stuck on the Saumsung boot up, it doesn't actually boot up into
the lock screen so I can't do anything with it, if you could help me with link to the SM-G928X firmware that I could use in ODIN
that would be greatly appreciated cause the phone is a paper weight at this point.
I had a moment of madness and decided to do what you said anyway, and I can't factory reset the phone from the recovery menu as it says
its due to security policies or something of that nature, which again I mentioned in the initial thread.
Also to clarify, I can't flash my own firmware because I can't find the firmware anywhere on the internet.

I have done a bit of research on your G928X device and I think you are in luck.
Check out this link carefully http://pdadb.net/index.php?m=specs&id=8759&c=samsung_sm-g928x_galaxy_s6_edgeplus_lte-a_samsung_zen
and you will see that the firmware in your phone is identical to many other G928 firmwares as you will see in that link.
Odin flashing any of the ZEN firmwares in that link cannot brick your phone, the worse thing that can happen is that it will not
work. (just like it's not working for you right now).
I would go a head and odin flash the S6 Edge+ G928T firmware which is also the ZEN baseband firmware, there are many S6 Edge+ phones
using the exact same firmware. All Samsung S6 Edge+ firmwares contain the modem but not all of them will be compatible with your
carrier but at least you will be able to boot your phone normally without getting stuck on boot screen or bootlooping to start with.
You can get the G928T firmware from http://sammobile.com OR
https://www.androidfilehost.com/?fid=24499762636004597 (fast download)
Good luck,
Have a great day!

Odin doesn't recognize my s7 edge (trying CF auto root)

Hi, I've been reading the thread for CF auto root to give it a go. I've downloaded the drivers (I've got 1.5.51 now installed, haven't been able to find later ones), I've got the 2.74 SU version that helps to overcome a recent security policy update issue reverting root status and the CF auto root zip file (CF-Auto-Root-hero2lte-hero2ltexx-smg935f.zip) which has odin 3.10.6 included (not quite sure if I can use any recent odin version). I even got my stock firmware com sammobile and extract the proper boot.img from the AP* file (just in case I got something wrong at sometime). I've enabled the OEM unlock too on developer options. I understand I can give it a go without having to go with a custom recovery (still not sure and haven't got the whole picture about the dm-verity thingy and what effects has on the device but someone mentioned something like loosing the encryption or so). This is my first try on getting root on my s7 edge G935F (international version), so it shouldn't have any boot.img problem (but trying to be prepare since I can't go about without my phone being working).
So, I've got my phone into download mode, started odin, loaded on AP the tar.md5 file from the CD auto root zip file (CF-Auto-Root-hero2lte-hero2ltexx-smg935f.tar.md5), connect the device throuhg usb cable and I was expecting Odin to recognize it but nothing happens. Since in the threads I've been researching for s7 edge there is no indication on waiting to see something happening on ODIN (but in some other threads - not s7 edge related though - mention something about having to see a blue indicator on COM), I'm not quite sure if I'm expected to just hit start even if no apparent change is happening on ODIN nor there is some drivers installing/configuring when connecting the device on download mode. Since I'm quite new to this, I'm no sure if I should connect the device first with some other option enabled, like USB debugging or if I'm missing something quite obvious for someone familiar with flashing with odin?
Kind regards for any help!
PS. I did tried to find an answer through searching but foung nothing related s7 edge wise so I'm at a loss not even knowing if just hitting start without having the device recognized on ODIN will do any harm at all (that newbie I am)

Thank you skinza for your reply, I did tried what you suggested and although it wasn't enough for getting it solved it helped me to know I was on the correct path and that I could use an updated odin.. finally, the problem was on embarrassing one since I went into download mode but hadn't push the volume up to get into the actual ODIN mode (too newbie of me but I was trying to follow the instructions I'd found and none were that specific - a bit afraid of messing it up). Nonetheless, thanks again for your time! Kind regards!
Edit: Now I'm rooted (thanks CF) and it took less than expected (a couple of mins or so). I didn't go the custom recovery way, so it might have been that.

Not a problem mate

Thanks again! for now I won't be going for a custom rom but wanted to be able to install a firewall to stop some apps from draining my prepaid data (limited)..
I was planning on having xposed installed but it seems I need a custom recovery for that as well.. I used to have xprivacy on a previous nexus 4 and loved I could limit some permissions that are still missing now on marshmallow but haven't got a grip yet as per the effects due to the dm-verity thing.. would you happen to know anything about it? and I was also wondering about if I do need to have the OEM unlock still enabled now that I'm rooted? (The later because I'd been robbed of my cellphones in the past - even recently a new s7 edge that didn't last me even a month and wouldn't want to let them have an easy pie on having the device available)
Regards!
I'm facing the same issue but even after going into download mode properly after pressing vol up
odin doesn't detect my s7 edge
I've installed all the drivers also

Got the same issue. I'm new with this. My colleague wants me to learn and test and load Lineageos on some brand new S7 G930F devices he gave me which I have already switched to dev mode with OEM unlock and USB debugging on and the devices smoothly jumped into ODIN downloading.... mode
I also have the proper Samsung USB Driver installed. (did it several times after ODIN didn't recognize my device)
However, according to the manual, I should start up ODIN, then connect the device via USB cable to the workstation (as unsuccessful I already tried 3 workstations with Windows 7 and Windows 10) whilst having the phone in download mode... .BUT NOTHING APPEARS in the Log field and the ID:COM Box doesn't change colour and my manual says that it should.
My workstation however recognizes the devices with positive messages so I guess the drivers are good.
My co-worker gave me ODIN v3.10, but as this didn't work I downloaded and installed V3.12, but unfortunately also without any luck.
What am I doing wrong?
which OS?
S7 edge SM-G935F
Hey guys,
i tried rooting my s7 edge but after i got into TWRP my phone went into a bootloop. when i got back download mode, odin still found my phone, though everytime i tried to enter TWRP again, odin said there was a FAIL and my phone immediatly went back into bootloop. I tried to reinstall the samsung usb drivers but now odin cant find my phone anymore.
Before i screw up even more, can someone please help me? right now im stuck in download mode and odin 12, 11, and 10 all wont recognize my phone, also not if i use different cables. my windows laptop however still gives me the device found and device disconnected sound everytime i (dis)connect my phone.
any ideas?
thanks
EDIT: Okay i tried my USB 3.0 port and now odin found my phone. just weird... now i just need to solve the problem that I'm still stuck in the Bootloop but that probably doesnt belong in this thread

SM-G900F unusual brick

its a european 32gb version samsung galaxy s5 SM-G900F.
the device is just over 2 years old never used rooted, since it wasn't mine.
i once rooted the device and reverted it back to official half a year ago or more.
been using the exact same PDA numbers (since that didn't work also tried different) for the official rom etc.
now during normal use, to be specific in a viber call.
the device suddenly shut off and went into a bootloop mode.
there are times the device just shows a black screen and after holding the battery out for some time it opens up again.
prior to flashing another stock rom through odin i just managed to get it booting after a factory reset holding the vol down button (safe mode)
and that is not consistent at all.
same goes as for recovery, with a lot of inconsistency i got it to boot a couple of times in recovery and once in twrp flashed through odin, tried flashing lineageos.
as i left the phone and came back i found it in a bootloop wich is unusual because twrp doesnt automatically reboot after flashing.
tried:
-cf auto root
-the european 32gb pit file
-repartitioning
-flashing multiple stock through odin
-fastboot doesnt recognize the device
-adb used to recognize, doesnt anymore
-flashing recovery
-another battery
-flashing cyanogenmod through twrp with no success
-flashing bootloader (and all else AP/BL/CP/CSC)
-tried samsung kies
-wiping cache, dalvik cache/ data factory reset (when recovery did to happen work out of luck)
the only thing working quite consistent is the bootloader through odin (no fastboot console detection) right now thats about all
and even then sometimes the phones screen is black during boot but after having the battery out for some time it works.
if i plug the phone in the charger it boots up in android but with a black screen.
i can notice because the lower touch buttons on the screen get lightened up and once i've heard the screen reader through the speakers.
it doesnt happen to boot to android without being plugged in.
so in other words im stuck with a phone on which no matter what i tried only has a working bootloader after unpopping the battery for a bit.
forgot to mention also the device always acts as if its turning on so it vibrates, either that results in a visual bootloop/or black screen not even reaching the roms logo (in the beginning sometimes did).
lately if it shows something after holding the battery out its just the galaxy s5 first logo and no rom bootup.
so its not that i press the power button and its completely dead
according to all bootloop brick solutions none of them worked as it seems its more than just that in my rare case
advice would be extremely appreciated
here is a picture of the bootloader

I read this and many other threads before but most if not all were solved with one of the steps i mentioned, furthermore it has always used and worked with sm-g900f roms and also states its a 900f in the bootloader unlike the experience with this thread

yes i tried another battery, also popped out the sdcard and sim card.
the same happens with a battery which is functional in another SM-G900F most of the time it just shows a black screen unless i leave the phone without a power source for some minutes.
after it just goes into a bootloop. or if i just put the battery back in the bootloader is almost guaranteed to work.
of the so many times trying i just managed to get 4 times in recovery or so.
well it still boots within android i can hear the narrator etc. just not with screen on.
i dont know how i did it but 2 times i managed to get it fully functional into safe mode.. not until a reboot. wonder why
also tried within odin flashing after researching options: NAND erase all, Phone EFS clear, Phone bootloader update, Repartitioning.
all combined when flashing full BL,AP,CP,CSC plus pitfile although ive read the pitfile is in the CSC if its not HOME_CSC. just to be sure for avoiding a brick.
despite this still same.
there is no way to create a backup and create an odin flashable file from a workin g900f right? ive read samsung locks partitions such as bootloader etc.
im sure this complexity is just a samsung thing, ive debricked phones even worse than this and somehow nothing appears to work.
what im currently having is a working phone with a black screen.
i can only go to the bootloader with screen on. the phone boots normally with screen off.
ive done nand erase all and all the above options i named on the latest PHN update meant for this phone.
simple solutions dont work since ive tried all, i feel i need to find a way to restore every partition to its original state with an older bootloader since ive read lots of people were experiencing this after lollipop or onto marshmallow.
can anyone help me a bit with ideas on this?

Galaxy S8 bootloop fix (ODIN, Smart Switch not working)

Hello everyone,
I know this is a topic that had already been widely discussed but none of the suggested fixes were able to solve my issue. I also was not able to post this into the recoveries forum thread as I have just made a new account and I do not have the permission to do so.
My galaxy s8 is now stuck in a bootloop on the Glalaxy S8 screen and it does not progress from there. I can access the download mode but that is about it. I am not sure how this happened as it was fine one night and then i put it in my pocket, and when I pulled it out the next morning, it was stuck in this bootloop.
I am overseas currently, and so unfortunately I am not covered by the local Samsung warranty, else I would have gone through them.
I have tried flashing the firmware which I downloaded from Sammobile, including the BL, AP, CP & CSC which has not worked. I tried using Smart Switch which does download and re-flash the software, but in both situations, my phone still remains bootlooped.
I am not sure if I am doing anything wrong in these steps. Please let me know if there are any other solutions I can try to get my phone working again.
Much appreciated!!!
