[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] gruuvin:
I bought this Exynos version because I wanted a Samsung processor, 8-cores, and not a phone that Samsung design-compromised for the two terrible CDMA carriers in the US. But since my carrier is T-mobile US, the Exynos version was a possibility that came with the price of connectivity issues (seems this is due to my phone's CSC being from Trinidad, and not finding an easy solution to remedy that).

When Oreo rolled out over a month ago, I just couldn't deal with the Samsung bloat on my phone anymore. I have been running the unofficial LOS 15.1 for the last month, which also comes at a different cost (not fully debugged, bad camera, etc.). I like LOS, but it does not do this device justice. I have been watching this thread to see if the reboot issues are worked out.

Well, I just installed this ROM, gave it NOVA, installed my 50 apps, then themed it with a dark Substratum made for samsung s7.

This OS is BEAUTIFUL! (oh PLEASE don't reboot)

So, I understand that the reboot issues have been due to Sumsung's bugged kernel source. Which kernel in this Aroma installer is affected by this? All of them? I don't recall what the three choices were, but I think we could choose from stock, superstock, and superman kernels? I selected superstock, and I had no idea which one to select, as the instructions on post #1 mentioned nothing about kernel choice. I wish we had more information about these.

Can anyone shed some light on the differences here? And what does and doesn't seem to make an effect on the reboot problem?

Thanks.

Oh, btw, I followed instructions to install brazil csc right after rom install, then normal boot, then back to recovery to install TmobileUS csc, and I have VoLTE for the first time ever on my sm-g930f. Wonderful!

I've got the reboot issue with superkernel. If you choose the superstock or stock and don't have the reboot issue keep using them. If not, flash an another kernel, that what I did and no more reboot.

Which CSC version did you use to install the T-Mobile US CSC?

I have AT&T and was waiting for Tkkg1994 to update the Oreo CSC after his vacation, to then install this ROM. Also, I have a coworker on Batman 1.5.0 S8 port and T-Mobile US CSC for quite some time and he has no problems with VoLTE/WiFi Calling.

Regarding Kernel, it looks that those who installed TGP Kernel have experienced no reboots.

---------- Post added at 02:18 PM ---------- Previous post was at 01:35 PM ----------

Can those using the SuperStock or Superkernel included in the ROM let us know if their phone has been reliable without reboots.

The TGP Kernel OP lists v6.8.3 which is based on ERH1. They have no links to older Kernels based on ERF4.

I installed this ROM last night with 3.18.120-SuperStock kernel selected in the Aroma installer, and so far, no reboot. I'm also running on the XXU2ERG2 baseband that samsung pushed with Oreo.

Do you know what's supposed to be the difference between the three kernels that can be selected from the Aroma installer?

The CSC link is for Marshmallow and Nougat. I don't see download links for Oreo. On post #12944 , TKKG states "Csc selection will be updated to oreo after my holidays". Has CSC been updated?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] gruuvin:
I dunno ??

I agree: there is no download link for Oreo, and I was faced with this conundrum yesterday. I wondered, "Why would Tkkg link from his Superman OREO rom to his csc selection tool that is only for MM and NOUGAT? and state with the link, 'you can use my CSC Selection Tool'?" "Why would he link to a Nougat selection tool from his Oreo ROM that has been up for quite a while now? Mistake?" Being the guy (Tkkg) that wrote both the ROM and the CSC tool, I thought maybe he just knows it pretty much works, and is just not being very explicit about it. So I gave it all a try. I had a backup of a previous rom and data setup, and was NOT going to flash a new modem and bootloader image, so if it all failed, I had a fallback.

install the ROM (https://xdaforums.com/galaxy-s7/development/rom-s7-rom-v1-0-t3356197 ),

immediately install the tzo csc (from brazil... this is instructed in my first link as a way to get VoLTE working in the US https://xdaforums.com/showpost.php?p=69864872&postcount=5484) tzo csc from the selection tool (https://xdaforums.com/s7-edge/development/utility-flashable-csc-selection-30-t3392957 ),

booted the newly installed rom (not even gonna do a brazilian setup),

immediately rebooted back to recovery,

installed the tmb csc out of the xaa multi-csc (yes; all from the nougat 2.5.0 selection tool).

boot the system with fingers crossed....

I wasn't out of the woods yet, because com.sec.android.AutoPreconfig package covers the screen with a message about the sim card has changed and the system needs to reboot to configure it (all you can do is press okay and reboot; this just boots to recovery to do nothing useful at all; and it loops this way when you reboot again)..... (here is details on that problem and solution: https://xdaforums.com/s7-edge/help/service-provider-update-restart-to-t3415738/page2 )

so I shut it down,

removed the sim card,

booted back up, and continued on setting up the rom,

rebooted to recovery and installed Magisk (need root access to disable the stupid sim card check),

then booted back into the system, connected to my device over usb with the adb shell, and did "su; pm disable com.sec.android.AutoPreconfig"

.... then I could shutdown, install my sim, and get on with my life!

It's all working now.

No reboots so far, and it's been a day.

Fingers crossed, because while it works, this is a NICE ROM!

... especially with Nova Launcher and Substratum Swift Black theme for Samsung S7

Hello guys,

Did anyone on SuperMan 3.0.x tried to go back to SuperMan 2.9 using a TWRP backup ?

I just wondered if it would be simple ?

My last 2.9 backup has the following partitions :

Boot / data / efs / modem / system

So I belive everything is included, especially older modem and bootloader.

Thanks !
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] gruuvin:
That's great news!!!

Including Oreo version of the xaa multi? Hope so! (looks like the current xaa multi-csc the the 2.5.0 version of the CSC selection tool is G935FOYM4BQJ5)

Any known undesirable effects of flashing a new CSC long after the fact (instead of doing it during ROM install).

I wonder why these instructions for getting wifi-calling working for tmobileUS csc

have us flash a brazilian csc immediately after rom install, fully boot the rom, then reboot into recovery, and flash the tmobile csc? That seems like a lot of trickery, and I wish I understood the reason.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] MatteXperiaU:
why this csc thing is so important to people? really no offense it's a question..i was wondering

Hey guys i did not flash any csc..just the ROM and magisk after booting up.. i m facing random reboots after the screen freezes.. most occuring in chrome.. anyone else facing the issue ? Is there any soln to it?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] natetokes:
What kernel are you using? The ones that come with the ROM give random reboots. I use tgp kernel and it works fine, no reboots.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] ashiskar:
Hey bro using the stock kernel for performance.. lemme check the other kernel u said..
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] natetokes:
Yes that's your problem. Clean flash the ROM, boot up, reboot to recovery, flash the latest tgp kernel and pick magisk and mtweaks during its aroma set up, reboot and enjoy your fully working ROM.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] ashiskar:
Already clean flashed.. cant i just flash the Kernel directly.. or the magisk will create an issue?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] thefuncooker:
I tried the same method (the Brazilian csc first), but with ATT instead of TMB. While the phone boots up and works, the IMS Registration Service fc on me constantly, and Wi-Fi calling or VoLTE don't work. Has anyone had any luck with this on ATT? I heard that some people had success with giving ATT a different IMEI from a G930A?

I installed this ROM with the included SuperStock kernel, and it's been running for about 40 hours without an unintended reboot.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] natetokes:
Not certain but as long as your using the latest magisk stable and booted up the ROM once before rooting it should work fine

They will come, no way around it. 40 hours is not even 2 days, wait a bit.

[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] gruuvin:
I've read the reboot problem is with the Samsung kernel source that? Has anyone narrowed it down further than that? To certain sections of the kernel? That some have no reboot issues and others are plagued with reboots seems to indicate there are more variables at play here. Unfortunately, it's hard to rule out the cases where people have dirty-flashed, since so many do it and report troubles without clean flash. It would be nice to put the problem to rest for good.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] natetokes:
Theres a few kernels with the mismatch fixed, the latest Superstock, tgp, & Moro.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] gruuvin:
Thanks for responding!

So, 3.18.120-SuperStock is an option within the SupermanRom installer, and that's the kernel I installed, mostly by a one-in-three chance, since there is nothing said on page one about what to select and what to avoid. Is that kernel fixed? Or only a later version?

What is the "mismatch"? This all seems to be quite vague. This ROM just seems to be an amazing solution to the old S7, but it's development is FINAL, and there's this black cloud of random reboots, with no specifics on what the fix is. I just want to shine a bit of light on the best solutions with this ROM; clarity is being abandoned along with it.

I kept reading your name as takenotes.... Lol, good job. Good name!
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] natetokes:
The solution is not to use the default kernels as the source code they're based off of was broken. It makes devices randomly reboot. I personally don't know why, I'm just a power user and not a developer. The superstock kernel thread says that version has the mismatch fixed but I've never used it so I can't confirm. Use any kernel based off a newer release than the rom and you should be just fine. Me & a friend of mine with an edge use tgp+superman 3.0.1 and either of us have yet to get a random reboot.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] gruuvin:
This is one of the choices in the installer, and I'll confirm that it's stable. Two days with no reboot. If I end up with a reboot, I'll come back and modify my claim.

SuperStock-Kernel V3.1.0:

- Source code based on ERH1

- Updated linux to 3.18.120

- Fixed samsungs mismatch in kernel compilation
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] gruuvin:
I just discovered that SuperStock kernel takes two of the fast cpu cores offline, shown by Geekbench and scoring poorly. Installed TGPKernel, and now all 8 are up and scoring well. I thought SuperStock battery life was awesome! Well maybe that was because of the two fast cores shut down.

I am on BatMan ROM V1.5.0 (Nougat). If Install The Latest SuperMan (Oreo) and decide to go back to BatMan, would It Work? I read the bootloader cannot be downgraded; what do I do In the case I wanted to go back?

I have previously Installed Havoc OS (Oreo 8.1.0) and was able to go back to BatMan V1.5.0; how is that possible?

One more question; Can the latest SuperMan work without upgrading the Bootloader during flash?

Which version of TGP kernel did you use? The TGP v6.8.3 available on XDA is based on ERH1 kernel and according to ?@Tkkg1994 still has instability issues. I have not been able to find a TGP kernel based on ERF4, the latest stable kernel.

I have tried many time to activate WiFi Calling on AT&T with Batman 1.5.0 S8 port, and other ROMs without success. Always get error EDS0008 during the registration process. Maybe faking IMEI from G930A would do the trick, but not sure if that is possible.

Im on an SM-G930F with SMR 3.0.1 and the superkernel and magisk. Though I still get some random reboots, usually after clicking on smtgh that is demanding or so, like for example exiting youtube fullscreen mode to show all the other recommended videos. I don't think I've ever had a reboot out of nowhere.

I can also add that it's pretty weird. I have a banking app, that even with magisk hide and all that stuff works sometimes and sometimes doesn't. Imagine it works right now; then my phone decides to reboot and it doesn't work anymore. Then on the next reboot the app might work again, but not for sure. It's strange. Also, I'm sure the magisk hide and such is working because pokemon go works always. So maybe this will help someone to investigate why there are random reboots!

With SuperMan v3.0 I had like a reboot once a day. I knew v.3.0.1 did not fix the random reboots yet but before I went ahead to install SM v3.0.1 I tried a clean TGP v2.4.1 installation out of curiosity.

Duh... it was way too slow/laggy compared to a clean SM installation. And I did all sorts of TGP v2.4.1 + TGP Kernel combinations: v6.7.2, v6.8.0, v6.8.3 and also v6.9.0. I also tried Lite, Standard and Custom TGP but nothing seems to fix the slowliness of TGP even after several reboots. I also tried not to install Magisk with the ROM installation at first, and flash Magisk after the first reboot as recommended with SuperMan, but that didn't do any change in TGP.

I have no idea how people get TGP to run fast. So finally I went over to SM v3.0.1 and it was like night and day, SM is still the smoothest custom ROM I tried for the S7.

I know the first random reboot is bound to come soon, as I am quite a heavy user :|

The most interesting thing however is that I didn't have a reboot so far, for almost 3, 4 days.

Fingers crossed that maybe one day Luca will find another old S7 again to fill it with life because the S7 is really a great device compared to all the other devices which have EOL custom ROMS.

Compared at release times I think the S7 was better than the S8 and probably the S9, even I might switch to the S9 someday... just my opinion.

When/where did he state that? I ran the SuperStock 3.1.0 kernel for a couple days with no issue, and it is ERH1. Tkkg claimed he fixed the compile mismatch, and calls it stable (that's what he posted about it in his kernel thread post 1 and 2).

TGPKernel seems stable too, and it was released yesterday based on ERH6 and Linux 3.18.122.
