Another thing I couldn't find a message about: my phone's battery gets to 81%. What I have read everywhere is that you only get 80% after rooting.

Maybe somebody can help me understand once and for all the CSC/bloatware situation: did I get the AT&T crap because the eng firmware set that CSC and then my XAA multi-CSC firmware went with what was already there?
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] HighOnLinux:
The battery part: mine got up to 82% But it's all random, it could go up to 80, 81 or 82 from my experience but it may vary.

The CSC part: i did get t-mobile bloat when my t-mobile sim was inserted so i would assume so.
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] Aruku:
Oh, that's right, now I remember reading about the SIM. I had my AT&T one, so that was it.

But, what happens if you do this process without a SIM inserted?

And in what part of the whole operation does Android check the card for this? I've never seen any screen or message related to it at all.
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] driike:
Didn't see this until now, I won't be able to test until around 8am est, but ill try soon as I get home from work. I did however try a 32g, 64g and a 128g card, they all sent me to the upload mode. I'm T-Mo if that might have something to do with it. I also did the ff flash with the zip and img on my internal this time

---------- Post added at 08:23 PM ---------- Previous post was at 08:20 PM ----------

Is there a way to update samsung apps other than apkmirror?

Update: had to pick my roommate up for work so I uninstalled ff, rebooted my phone, turned phone off, put sd in, 20 minutes later got sent to upload. I'm not really proficient in adb without seeing instructions for what I'm doing, is there a way I can do this and maybe pull a log with adb after it happens so we can figure this out?
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] HighOnLinux:
That i do not know myself. You will have to find out with someone else. And since I'm not proficient with the OS, i don't know entirely what the procedure android has to configure your current SIM card. From my guess (not saying i know anything here correct me if I'm wrong), it involves on altering the CSC file a tad bit so the phone could work on the right bands, and the right network. So no network issues will occur during the meantime. But again, correct me if im wrong anyone.

---- After it boots into the initial Samsung Galaxy s8 screen with all the white and blue letters, then it loads into the set up process and I noticed that whenever the phone service turns on it freezes then the phone turns itself off, it then boots into upload mode with the Modem failure and stays there. I am able to flash with the official Odin, the stock firmware and get back into recovery mode and return my phone back to stock. But everytime I try to flash the modded 4 files with the modded Odin, everything goes success, then boots into recovery mode, then I select to reboot the phone, then it gives me the subsystem crash: Modem. I have tried re-doing this whole process of going back to stock, redownloading the files, and making sure i'm following the steps correctly but I keep ending up with the Modem issue. I've attempted googling this issue but I have had 0 luck finding any solutions, it seems like I am the only one with this problem.

--- I am using the Galaxy s8 with Verizon

--- I will also note that the first time I followed this process, everything went smoothly up until the point where I was doing the final steps with flashfire, and making sure every single setting was correct step by step to the teeth. After pressing flash, and letting the whole flash process take its course, the phone rebooted into the current Modem failure I am getting now.

Any help would be appreciated, thanks!!

I searched the thread but the forum was returning posts with "Odin" (???) highlighted instead of my search term: what is the OTA/update situation?

The phone says the software has been modified and to go get lost when I check for updates, but can I download some package and flash it to update without losing root?

Also, why does Android says the software has been modified but Knox is still 0x0?

For those having issues with the phone app disappearing, phone calling, or their Call app crashing, I have a Phone app fix that worked for me.

If you disabled the Contacts app, reenable it. (idk if this is the problem)

Download Rom Toolbox Lite from the Play Store

Open it. Go to the App Manager.

For these apps:

- Phone

- Phone

- Phone [One of them might be called "Phone VOICEMAIL"]

- com.sec.phone

- Dialer Storage

- Assisted Dialing

Select each app, go to Advanced, and Fix Permissions, Clear Data, and Clear Cache.

The Phone app should pop up. If it doesn't, try restarting first, and then reply "rip it didnt help" and we'll troubleshoot.

I'm on Verizon QE3, using the regular 1.0 method and flashed with stock Verizon QE3 Firmware.

You forgot to uncheck the preserve root option when you flashed in flashfire. You have to start over now.

How to apply latest S8 Snapdragon firmware after root

Hello all,

Can someone explain to me the process of updating phone with latest firmware without loosing root?

Thanks
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] HighOnLinux:
Its basically following the part of the op instructions with the system.ext4 file. Dl the updated fw file, extract it, find the system.ext4 file, copy it to your phone, put airplane mode on, then the rest is basically on the op but gl to you updating your phone
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] zdog7:
Thanks.

So it sounds like my setting I have done after the root will be lost, is that right? I will keep root but lose personalized settings?

[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] Synthio:
I've been searching for this problem, maybe I'm not using the right search words? But, is anyone else having sever slow downs when editing anything in system folder with a root browser? I've edited folders/files and every time I do suddenly the phone has extreme lag every time I open an application. Typically if it's one that needs root access. I've actually done the complete rooting process 3 times due to this. Something must be happening in the background because it sometimes even causes the phone to turn off the screen and my lock screen just does not work sometimes. I will attempt, for example, to put my pattern lock in, but I have to try 3 or 4 times because it will freeze the moment i touch the screen and the turns the display off. Eventually it works, but then applications slow to a halt for a few seconds whenever I open them, again usually, but not strictly, root applications such as root browsers.

Best I could find in this forum was something to do with a bug in the eng firmware, but it wasn't clear if they were having the same issue as me.

Sorry if this is posted somewhere, I just cannot find anything like this posted using the search tool. I've tried multiple threads too and can't find anything. Even the S8+ forum.
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] HighOnLinux:
In the beginning when i barely got root on my phone, i had the same slow downs, forcing me to boot into upload mode due to a 'unknown error' but just let it do its thing when you turn on your phone and don't rush anything because it will be unresponsive and frozen, forcing you to hard restart your phone. If it doesn't work, i'd recommend a factory reset instead to start clean and fresh without loosing root since supersu is obviously part of the system now. Report back the results.
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] Synthio:
Factory resets and anything that cleans the root filesystemr work. The problem is that I'm using unbugged modifications to folders and one thing will cause the thing to go down. I mean, I could simply go to like build.prop, edit/add one line, and the whole thing just bugs out. Total slow down. one thing could take 5 minutes because I have to wait for whatever it is doing in the background to finish. It's system wide. In fact, i just did a system.img update and all I did was copy the overlays folder to /data and edited generic.kl to edit bixby button and the whole thing slowed down again. Even more meaningless things like adding one line to build.prop to stop boot animations causes the thing to lag for minutes for everything. I mean, [MENTION=3812611]elliwigy[/MENTION] is this a known bug? It's like the whole point of having root, access to file systems, causes the phone to act like a nexus s.

Btw, any edits I do to the phone that then cause the slow downs, I return them to stock, and it still doesn't fix the slow downs.
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] HighOnLinux:
Well this is fairly new to me just like a couple of other issues. When i had root, the only issues i had were unresponsiveness from greenify, using the phone on boot up in a hurry and having screen issues. But i have messed with build.prop files on my s8 when i had the root before i switched to stock again and i never ran into slow downs, just constant wifi networks being forgotten and constantly putting in the password over and over again.
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] Synthio:
The only kind of connectivity issues I ever had was with bluetooth once. I just rerooted completely starting with odin and that was fixed.
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] RypeDub:
I attached the information about my phone.

Yes: I do not mind that my personal info is out there.

Feel free to reach out via SMS, MMS, VoiceMail or Phone Call.

I purchased it from VZW.com

I just want to know if I can root this phone and run SuperSU to the max.

I don't care for ROM's or TWRP or unlocked bootloader, unless those can enhance the capabilities of SUPERSU.

I need to be able to execute full root to any app requesting.

How do I back up what is currently on my phone?

Can I restore it after I'm root?

How could I go about that process?

I also watch Netflix and play Pokemon GO and would like 100% battery capacity. I also have a 64 GB unit.

How can I make sure to properly prepare for my needs, usage and habits?

Let me know if you need any more information.

I can follow instructions as long as they are correct. I will be as detailed as I can to help you as much as I can, so you can best help me.

Thank you.

For those asking about (aboot) the Canadian SM-G950W, I have your maple syrup right here. I've been trying a bunch of different stuff all day but I think I've finally found success.

If you use a system.img.ext4 from a Canadian carrier's firmware, you'll end up with repeated and constant crashing of the phone app that makes the entire phone unusable. Use a system.img.ext4 from a SM-G950U and it will work. I'm now using the system.img.ext4 from G950USQU1AQGL_G950UOYN1AQGL_CCT firmware downloaded from sammobile.com, and so far so good (with the exception of the 80% battery bug that everyone is getting). I'll report back if any problems pop up.
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] Aruku:
Does anybody have even the slightest idea about what causes the battery limitation? Is there some restriction built in on that eng firmware for whatever reason?
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] jiffyjeffsd:
I did uncheck that.

So,I'm pretty sure I flashed the wrong system image file...???

My skills are very basic,and I tend to fumble through this stuff until I get it.

Might try again today.

Thanks again.
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] HighOnLinux:
If you look at OP's post, you will see the side effects of rooting. You WILL LOSE netflix and pokemon go due to the safetynet api they use, and if you follow the procedure for root, you WILL NOT achieve a full 100% charge anymore due to the firmware settings the engineering fw has. If you do decide to go for root still, you can back up your current data via smart switch PC and/or samsung cloud. You could restore your data anytime, but take note on which day you created the backup. To prepare for getting root, you will have to download ODIN and Modified ODIN from OP's post, download the eng. Firmware from OP as well, download any stock firmware you'd like (T-Mobile, Sprint, Verizon, Etc.) From either www.updato.com or www.sammobile.com and lastly, get any zip file extractor to your pc so you can get the system.ext4 file from the stock firmware when the time has come. I wish you luck on getting root access properly and if you need more help, ask the thread.

Cool so for Verizon versions, or well I guess I have the U version I shouldn't have to worry.

I'm heading into work now and will prep my SmartSwitch backup, all downloads and the tutorial.

Another user mentioned backing up a file so that Netflix will remake it and a few other users reported that it worked for them.

I wonder if the same method will work for Pokemon GO.

How do you extract the eng.sys4 thing? I wanna poke around and see if i can help with the battery thing.
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] HighOnLinux:
Do you mean the system.ext4 file? Well it's part of the procedure by extracting the zipped file of your stock firmware and you extracting the AP file alone in your zip extractor you should of downloaded already to prep for root. After you extract the AP fw file using the zip extractor, you should see the system.ext4 and transfer it to your s8. Afterwards you put your phone on airplane mode, open ff (flashfire) and follow the exact order on the OP. And another workaround for netflix is getting a apk for it on a website. But you will no longer find netflix (and i think pokemon GO) on the play store. If you manage to download pokemon go though, you can't play it due to the safetynet api the game contains. The only way you can bypass that problem is having magisk but that's impossible as we speak, since we don't have a unlockable bootloader yet.
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] Smithfolk4:
I agree with the Greenify comment. If I install Greenify I get unresponsiveness that lasts for a long time. I can boot into upload and get the unknown error screen, then reboot from there. Without Greenify installed I have not had a single issue.

If i root my G8+, will I lose Samsung Pay?
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] HighOnLinux:
Yes. You will be losing samsung pay, secure folder, samsung health, and anything else that depends on knox
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] Synthio:
Greenify actually doesn't give me issues. No root app really does. It's only when I modify a file in the system folder, like build.prop or overlays for themes, or media-mixer when attempting to get that stereo speaker. Any files I modify and cause the slow down I put back to original of course; like media-mixer, but it won't fixed the problem. Once it's messed up, it's messed up. Until I wipe system with a new system.img.

Kinda sucks because you can get to a point where it's like wow I got it looking and running just how I like it, then you try this one thing and BAM you have to start over again. I know the risks of modifying files with root, but with all the phones I've had I've always rooted and haven't had this sort of thing happen. Plus, I can't seem to find someone with a similar problem.

[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] Smithfolk4:
It is interesting that some different phones have issues with different things. I haven't tried to edit build prop or anything like that because I would probably mess it up. I only do that if I have something specific to do and someone has given me instruction on how to do it.

I am really confident that Greenify causes me issues. I don't want to install it again because every time I do, I have problems. I can get out of it without wiping, just have to reboot, but I am not getting that much better battery with Greenify.

Since you can't find the right firmware, you could just use the unlocked firmware to aid you. Nothing will be different. Not in this case since i flashed the U1 firmware for root and i got the t-mobile bloatware and boot up screen

init.rc

# ...

This causes the internal data to symlink to the sdcard directory. Thus, when you mount an sdcard it will throw a CRC error because the files on the sdcard are different then the files in /storage/self/primary

I don't have an external SD card, but maybe free AParted app from Google playstore would help? AParted is for rooted phones, but

[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] jhofseth:
We can't have proper/normal init.d support because that requires editing boot image. Have you flashed your carrier's latest system.img.ext4 in FlashFire (wipe+latest carrier-specific system.img.ext4+stage 2 supersu zip), then flashed latest carrier-specific CP+CSC in latest Odin? I would first try AParted (requires Busybox); but, you will lose data on card, so backup first.
