You can use stock odin to flash up to Nougat if you have the firmware for odin and your phone. Alternatively you can flash same stock MM firmware or any newer MM firmware with stock odin and then take ota upgrade to Nougat. Keep in mind you can only odin firmware that has the same version bootloader (bl file) or newer so make sure you don't go further than you want to go.....although there is some overlap in firmware revisions using same bootloader version.

Not totally sure it's available for all carriers but if you can find a home_csc file it could keep you from losing your data in the process. You could also just leave the csc file out and try that but I've read mixed results doing that way. Otherwise just do the full stock return/update and let any data you didn't previously backup go.....cleaning house in a way.

V15 fix for any samsung galaxy s7 is only one anyone should be using and it is still the same v15 fix it has ever been......hence the version unchanged from v15.

---------- Post added at 02:40 PM ---------- Previous post was at 02:37 PM ----------

You are correct no backtrack, at least by bootloader revisions. So find your current firmware version by searching, it's out there, check xda, updato.com or sammobile.com or xda or theandroidsoul.com for firmware or search Google. Then use stock odin 3.12 or 3.12.3 to go stock. Princecomsy is only for engboot kernel.

---------- Post added at 02:41 PM ---------- Previous post was at 02:40 PM ----------

Correct.

---------- Post added at 02:45 PM ---------- Previous post was at 02:41 PM ----------

You asked and answered all your own questions correctly. Good reading. If pk1 is what you were on then that would be what you want to stock odin unless you want to go up to Nougat. But you could use pk1 and then ota Nougat if at&t has available. Stock odin to go to stick firmware. You seem like you know what you're doing.

---------- Post added at 02:49 PM ---------- Previous post was at 02:45 PM ----------

I agree. Especially if you're going to odin the engboot kernel and root.bat because the best results seem to be from phones that were completely stock and fresh without any settings that might interfere or get in the way.

---------- Post added at 02:55 PM ---------- Previous post was at 02:49 PM ----------

You need to use odin to flash the stock firmware not flashfire. You can go back to pi3 as long as the bootloaders are the same....you can't go backwards. So check into that. Not sure if lag is better on pi3 vs pl4 but you might want to wipe your cache from flashfire or from the phones recovery and that might help too. But also it can take several hours to a day or so and also reboot a few times for things to settle in. But wipe cache should help.
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] Thurein Phyo:
Thanks.

I'm convinced what you mentioned. So if you don't think going back to PI3 won't do much good for lagging, what about going all the way back to G935UUEU2APEH? What do you think?

I do my works with my phone; surf, calls, social medias. So I use my phone a lot. So I just need it to be as fast as it can. Though my OS doesn't need to be fancy, I also don't want my phone to function well. I don't know anything about PEH cuz I've never used it before. So can you guide me please.

Thanks in advance.
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] Thurein Phyo:

Yes, I would like to wipe cache from Flashfire.

[Verizon Samsung Galaxy S7 Guides, News, & Discussi] saf4xdadev:
Those three that come up by default are good plus cache partition. If you just odined engboot kernel and root.bat onto a newly stock phone then those are what you want. Alternatively you can go into phone recovery (pwr button+home button+volume up button all same time from powered off phone) and wipe just the cache partition. Either way should improve things.
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] Krog18:
Oh boy, if I'm reading this right he only wants to wipe his cache? If he leaves those 3 selected, he'll wipe all of his apps, data and internal SD card same as factory reset. Those 3 are generally what you'd wipe when flashing a rom.

Yeah my bad. I was thinking one thing but typing another. I guess maybe one shouldn't text while driving. I did get to that at the end about wiping cache from recovery.

If starting from a stock phone there shouldn't really be any third party apps or any app data that really matters though, so it shouldn't have hurt anything. But I see your point.

I thank him very much. He tried to help me.

But he didnt read what I wrote or answer my questions properly.

Can you please help answer my question?

---------- Post added at 10:33 PM ---------- Previous post was at 10:19 PM ----------

Hi,

Hi.

Mine is SM-G935U, Unlocked US edition. I upgraded to PL4 via OTA from PI3, the stock version.

Then I felt the battery drains and some lags.

Then as I desperately need to install my native fonts, I successfully rooted mine with your guide.

Then I felt extreme lags, so I also follow the step, flashing the Fix script flashable zip with FlashFire, after rooting. The lags was so much better, but still the lags is present and pretty bad.

So my question is:

1. I was thinking, if I root with my stock version PI3, I think the lags won't be this bad. So can I go back (flash) my phone to PI3 via FlashFire? I've heard that flashing (especially upgrading) via FlashFire can maintain Root? Does that work the same for downgrading via Flashfire? Will I able to maintian my Root after downgrading from FF?

And Will I lose my data? Or do I have to use Odin? If I use Odin to flash, I know I will lose my data.

So if the answer is Yes, I would like to downgrade all the way back to G935UUEU2APEH and follow this engroot guide in this thread again. And I think the lag problems will be so much better.

What do you think?

I do my works with my phone; surf, calls, social medias. So I use my phone a lot. So I just need it to be as fast as it can. Though my OS doesn't need to be fancy, I also don't want my phone to function well. I don't know anything about PEH version cuz I've never used it before. Is that version suck? What version (PEH or PG9 or PI3) do you think will be the most suitable for my situation?

Thanks in advance.

[Verizon Samsung Galaxy S7 Guides, News, & Discussi] saf4xdadev:
So you're on verizon pe1 firmware so assuming your on an early bootloader revision like v2 maybe as well, you should be able to odin any stock verizon firmware package that starts with g935vvru2ape1 on up......your choice because you can go up in bootloader versions but not back. Some firmware versions have same bootloader revision so there could be some overlap for certain versions. Also, It should be stock odin for stock firmware and Princecomsy for engboot kernel.

Alternatively you could try to do a factory reset from phones recovery. Then that might let you back into phone and you should still be on the engboot kernel.....unlocked custom padlock on boot screen. If that works then you may be able to reroot by same op instructs and root.bat script.

Something I noticed is Odin does not have any actual connection with phone. Before flashing anything you need to show a connection between phone and computer. You will know when Odin shows an active com port.

Check

USB debugging and also authorize phone in adb connection to start

Have you tried using a kernel app to adjust your cpu settings? I'd recommend trying kernel adiutor and set the cpu to conservative to see if it helps any before you go flashing different fw's and such.

I don't know a whole lot about the U fw versions as I have Verizon and follow that pretty closely. I've heard mixed results with the U fw.

Yes, you can downgrade from N to rooted MM. You have to odin the stock full MM firmware (including the bootloader) then root. Just make sure you use a V4 bootloader/firmware for your device. Not sure what variant you have, but the most recent version of MM for your device would be fine.

Trouble disabling the voLTE icons

First time XDA poster. I recently bought a Verizon S7 and decided to root it.

I'm assuming you're trying to replace the stock imsservice.apk with a different version, in which case you don't INSTALL it like a regular app, but rather manually copy it to the proper folder with a root file manager such as Root Explorer, set the proper permissions (usually 644), then reboot and test.
