Buying Galaxy S7 only for running LineageOS? (Coming from OnePlus 3) - Samsung Galaxy S7 Questions and Answers

Hi!
Would you recommend buying S7 to run LineageOS? I hate TouchWiz (and everything else beside Stock Android), but I like the phone. I had OnePlus 3 running OxygenOS but unfortunately I lost it, and I don't want to buy the same phone again, though I was really happy with it.
Thanks for suggestions

Makes more sense to buy the phone you were happy with and know runs well with the OS of your choice than an S7
It would need to be the International Exynos S7, the US snapdragon S7's are all bootloader locked, no custom ROMs or recovery for them
Wouldn't it be better to buy a Pixel or something with vanilla android if you hate TouchWiz which is what Samsungs are all about?

Not a good idea. Camera will turn to crap on LOS.

Please - you can unlock the bootloader on the Snapdragon (US) S7s - in fact, you can still run stock on such an S7 (my own S7 has been BL-unlocked since the launch of official Nougat - which predates LoS on any S7). The issue with the Snapdragon S7s is the lack of root and third-party recoveries (and third-party ROMs, for that matter) - none of which has been solved yet; however, it has nothing to do with the bootloader. There may be other issues - however, that isn't one of them.

Since when have you been able to unlock the bootloader of the Snapdragon US S7?
Root has been achieved
And I discovered today flashing custom ROMs using flashfire has been achieved, but not unlocking the bootloader

Bootloader-unlocking predates both using Flashfire and gaining root - the bigger problem, in fact, has been avoiding tripping Knox (though that's been done as well) - and Knox has been a PITA going back to the GNex.
Also, LineageOS is still Exnyos-only (there is no version for the Snapdragon-based S7).

Well, you couldn't do that. As far as I know the Knox Chip is eFused, so once it got tripped there is no solution to come back from.
Both on Snapdragon/Exynos version

To Root or Not to Root

Hello Community!!
I have owned many androids over the years, and have recently got an S6, hoping to dive back into the game of rooting, modding and messing around until my phones works the way i want it to. There are MANY things that really Piss me off about my T-MObile variant of the S6, including the horrible battery life, bloatware, and lack of personality. I Really would love to root my device, but KNOX. OMG what is this?! If i Root, no Samsung pay? What other downsides are there to rooting? But recently, my phone installed "ANdroid Pay" SO I am thinking, I should just root, forget Samsung pay and just use Google pay or whatever they call it.
As you guys can tell from my sig, I have been very inactive on these forums. I am hoping someone can give me some advice here---
Thanks So much

There are pros and cons to root.
The first pro is limitless customizations and personalizations.
The first con is OTA updates get disabled.
Another pro is you are able to dramatically improve battery and overall performance using various apps.
Another con is your warranty will be void, assuming you tripped KNOX.
If you trip KNOX, Samsung Pay no longer works; if you have root (even without touching KNOX) Android Pay does not work.
I obtained root just to prove to myself it could be done.
Since then there have been dramatic improvements with speed and battery life.
Package Disabler Pro can freeze a lot of the bloatware without root: https://play.google.com/store/apps/details?id=com.ospolice.packagedisablerpro&hl=en
Hi,
It's a highly personal decision. I myself for the first time am holding on rooting - I was the one who made the most famous Xoom rooting tool and also S4 Linux Root Script, so that tells a lot. The thing is, meanwhile my device is satisfying my needs, and I'm really curious about Samsung Pay, as it has a way wider support than Android Pay and other systems.
The best thing about rooting in my opinion was the endless system customization - specially after Xposed was released. The way better data management I had, better system control and some exclusive apps that require root or works better with root. If you are really pissed about Samsung TouchWiz apps and system "features", rooting would be a nice idea. Just keep in mind that after rooting Knox will be tripped and there's no turning back with Knox. Depending on your country, Knox trip also means warranty void, because once rooted you can unroot and make it looks like nothing happened.
Just adding what was already said, but Android Pay doesn't work with root.
All the best,
~Lord

Rooting doesn't allways mean tripped knox. I have my G920F rooted and knox intact. This can be done even after updrade to 5.1.1 stok firmware.
An android phone for me is worthless without root permissions. I need it for:
adaway adds
iptables (firewall)
better battery life (debloat)
titanium backup

I was only aware of root that can be applied before upgrade to 5.1.1.
Can you advise how you applied root after 5.1.1? Thanks.

Just install de 5.0.2 engineering bootloader via ODIN. Then instal TRWP via ODIN.
After this two steps you can flash whatever you want via TRWP.
Edit: with the 5.0.2 bootloader you will loose fingerprint scanner, the rest works great, at least with the custom rom I am using.

Keep in mind this engineering bootloader does not work with all variants. For example there is no Eng Bootloader for the Canadian phones.
Thank you both. I have the international SM-G920F (technically it's the dual Sim version, SM-G920FD, (from United Arab Emirates)).
So, to confirm, would the eng boot loader still work on my device variant, and allow root without tripping KNOX?

I have the single sim version of the G920F, so I don't know if it will work with the dual sim.
I don't think that it will strip you knox...
... and I think that if your phone doesn't work with this bootloader, you can just flash the correct one and make it work again.
But these are just guesses... you decide if you want to take the risk.
Good luck.

Hi,
I wouldn't risk that "you can just flash the correct one and make it work again". If you know how a bootloader work, if it gets broken there is no way to get to Download Mode and flash a new firmware/bootloader.
For information sake, a bootloader is a piece of software that is the first thing loaded when you boot your device, it comes before anything, be it kernel, be it recovery or anything else, that means, if you have a broken bootloader, the moment you try to boot your device up, it will try loading BL and it will fail, so it will shut down back again. I've had a broken BL once before on S4, the only way to recover was a direct flash of software in system chip using a tool called JTAG.
So, all I can say to users who still didn't get it: beware with this. It seems that many people are getting successful results, but it's an extremely risk procedure, make sure you read every single instruction and follow it, the possibility of a hard brick is high.
Even still, it's a great find, thanks for sharing with me, I didn't know of this until early today .
All the best,

I wonder whether Samsung pay will work again after reflash stock rom after root? Is it like knox, once rooted you will never have it no mater what you do including going back to pure stock?

Did you mean, once rooted we can unroot and install the stock firmware and hence tripped Knox will be restored as well?
Or the unrooting will only help to restore the stock but the knox will continue to remain tripped. I would like to know this as I am considering purchasing S6. The last samsung phone I owned was S2 and used that for 3 full years with out any problems.
Thanks.

Once Knox is tripped its tripped but, yes you can flash original firmware and as long as you factory reset it, it will be unrooted and ready for official updates.

Thanks. But can you be a bit more specific of if the unrooting, flashing stock, and factory resting will finally untrip the tripped Knox as well? My question in the event I need to take this back to a service center to claim warranty for whatever reason, is there any way for them to know that I have voided warranty if I unroot, flash back the stock and factory reset?

Once tripped there is no going back. Voided warranty depends on laws of your country and your retailers policy.

YOU CAN NOT UNTRIP KNOX, you can reflash your firmware from Sammobile, http://www.sammobile.com/firmwares/database/SM-G920F/
use odin and then after you flash, go into recovery or use system settings and conduct a factory reset. It will say Official in the status but, since they will reflash your rom anyways, they will see the knox trip.
It depends on where you purschased your device whether or not they will warranty it with Knox tripped.
Honestly, anyone who roots should understand this information before hand. You should always know how to return to stock unroot.

After rooting my 5.1.1 without tripping Knox, with the 5.0.2 engineering bootloader (as as described a few posts ago) I have flashed a stok rom with odin and then everything went back as it was before the rooting procedure.
1. I was on stok oficial rom with oficial bootloader.
2. I lost root.
3. Knox was still intact: 0.
4. Fingerprint scanner and MyKnox worked again.
So: after upgrade to 5.1.1, rooting with the 5.0.2 engineering bootloader seems to be safe and also easy to bo back to stock... at least for my model (G920F)

Question about root s8+ 2aql1

Hi i have the s8+ unlocked version and i try the root by samfail tutorial but not work and the thread is closed so i dont know if anyone know how to root s8+ xaa g955u1 bootload 2AQL1 (unlocked version) please share thanks
Snapdragon rooting is pretty standard, however I believe there is a question on a new boot loader coming out, so I'm not sure if that changes things, as one new addition is it keeps the phone region locked.
I'm Exynos. Your phone is?
does anyone have the stock boot image for s8+ 955FD
tryin to change root frm su to Magisk
I have the snapdragon but using unlocked version so the bootloader maybe different, i can use the custom rom but cant root? The custom rom have alot of extra feature that i dont like

I think you do not 'have' to use a custom ROM for Snapdragon, if you do not wish to use one. I believe you can just use the "U" version, which is Cell phone company featureless.

rooting VVRS4 ?

Hi,
I just bought a Like new S6.
I thought I was getting a factory unlocked device, but I got a Verizon unlocked phone (for other carriers) and full of bloatware from Samsung and Verizon.
I can still return it, but before doing so, I was looking for options about rooting or installing a different ROM.
it has Nougat 7.0, Firmware G920VVRS4DQI1, Kernel 3.10.61
As I understand, currently there's no way to modify anything in this model, right?
Should I return it?
Thank you for your replies

S7 g930A Rooting/TWRP

Hi guys, I've been doing some searching but haven't found any clear answers on recent threads.
I have a Samsung Galaxy S7 G930A, currently running Android 8.0, I have developer options unlocked.
I'm looking to install TWRP, update BL/Modem, install Lineage OS 15.1, update GAPPs, and root with Magisk 17.2 with the hope of debloating preinstalled apps and increasing my battery life.
I'm having trouble finding the correct versions of things for the G930A, it seems like most options are for the F/FD, I found this awesome thread for those which I assume is incompatible with my device: https://forum.xda-developers.com/galaxy-s7/how-to/guide-onelatest-stock-fw-csc-root-t3702963
Step one is installing TWRP (right?) but on their website under S7 has options for many models, but not the 930A. Is there another option that I'm missing or am I out of luck?
Thanks!
You're out of luck, TWRP and custom ROM's are only possible on models with the Exynos SOC which is the international 930F/FD model + Canada and Korea, as they can have their bootloaders unlocked.
G930A runs on Snapdragon with a locked bootloader (thanks to US carriers), despite the developer options unlock being visible, it actually doesn't do anything on Snapdragon.

Such a feat is not possible on the snapdragon version. Yes I know, their kind of scumbags for locking the qualcomm variants and only allowing the foreign versions with their crappy exynos chipset to be unlocked. It wasn't U.S Carriers that are responsible for the device being locked. Samsung locked it themselves.
Fortunately you can still root this device however, but you just cant install custom recoverys, boot logos etc,

Samsung S7 (Verizon) rooting and custom rom general questions.

I've recently been given a Galaxy S7 (Verizon branded) phone that I'd like to root and put a custom ROM on. I haven't done this in 3-4 years and based on what little searching I've done it seems this is workable for the S7 phone. I'm familiar (but very rusty) on the rooting and custom ROM process, but I know it will come back to me once I get into it.
I'd also like to have the "SIM card missing" message go away permanently if I root and custom ROM the phone. I will never use it with any service. Can someone enlighten me on what you feel is a good ROM for this phone and if the SIM message can be disabled since I'm never wanting to use it as a phone (on a service)?
You can't get a full blown custom ROM on Verizon variants because of snapdragon bootloader lock, only Exynos has custom ROMs.
You can get root using an engineering bootloader but it depends on what version your firmware is at.
You'll want to check out the Verizon S7 forums for how to do that https://forum.xda-developers.com/verizon-galaxy-s7

Thanks Beanvee. I think I'm trying to use a sledge hammer to fix an issue anyway.
I'm never going to use cellular so I was thinking a ROM would enable me to turn off the "No SIM card message" or have some feature built into it.
There might be other ways to do this besides rooting and a ROM. Thanks.
