[Sprint Samsung Galaxy S7 Questions & Answers] Mohamedkam000:
It doesn't matter which version of Android you are using, root is the same.

However, on stock ROMs, it might sometimes get rough, as you may end up with Wi-Fi not working (happened to me Q1 2020).

If you really want to learn how Android OS works, then rooting the stock ROM is not your way.

Try AOSP ROMs, preferably start with Oreo ones, you can root in 3 common way, LineageOS SU Add-on, Magisk, Super SU.

But before you tickle your phone, you have to make a backup of your current device, of every partition, EFS is the most important partition, so make sure it is safe.

Baseband version doesn't matter a lot, unless you're paranoid with updates, it is sorted alphabetically, each string on its own.

The phone is more similar to a linux machine than to a Windows PC.

Edit: To root stock ROM, you have to flash dm verity, so you don't end up encrypted again.
[Sprint Samsung Galaxy S7 Questions & Answers] CitizenSmith:
Thanks again for clearing quite a few things up :) I thought rooting stock rom would have been far safer way forward wow how wrong was I! but I guess I am just trying to find any kind simile to windows in any way but as you pointed out again it's more like Linux which again I've only played around with ubuntu and mint for a short period so again not to up on Linux lol.

It's funny I was just reading up on AOSP ROMs then got your message. I see they have a stable but not complete! Android 10 not that I would consider it need as I need a stable OS so Oreo is fine for me.

I have backed up phone using Smart Switch on the PC I assume that copy's every thing that's needed, I reset the phone in anticipation all be it prematurely :) but at least it restored all my data so if anything that was a good test of the back up at least .

I will have look at some AOSP ROMs and see what's involved there, I'll check out their tutorial hopefully it will include the whole process including root.

I gather by your comment using a AOSP ROM you don't need to use dm-verity or will that still be needed!.
[Sprint Samsung Galaxy S7 Questions & Answers] mooms:
The first thing to do is to flash (install) TWRP, it's a custom recovery (think of it as a mini OS that can boot before Android), that will be the base for any of your future tinkering.

Here is the thread, read the FP carefully: [Recovery][Exynos] Official TWRP for Galaxy S7 (herolte)

Once TWRP installed, you can do many things:

Install addons like Magisk. Magisk is the tool you use to obtain root. Forget SuperSU, its outdated, and don't works in modern versions of Android.

Install a custom ROM (this subforum is the perfect place to find them).

Backup & restore an image of your current ROM (very useful).
[Sprint Samsung Galaxy S7 Questions & Answers] CitizenSmith:
Thanks Mooms for the input :)

I tried to follow your links tutorial which he gives three options only one is any good to me and that was installing twrp using Odin but I'm having issues at every turn!. I can't even get Odin to recognise my phone it just wont pick it up I have Samsung driver installed and I have reinstalled many times I found an article claim to have a workaround but that was BS just selling some other app I even change the driver as described on there page,

but that did nothing so reinstall normal driver again.

feels like it's just not meant to be :/

Thanks again.
[Sprint Samsung Galaxy S7 Questions & Answers] Mohamedkam000:
AOSP ROMs are pure, you can't say they are not complete. They are complete, and what OEMs do, like Samsung and Xiaomi is just a customization that you can do, too.

It is preferred that when you take a backup, take it with TWRP, just to ensure you backed up phone's partitions, along with "EFS".

The root procedure on Android 6+ is done by patching the Kernel (boot.img), so unless you take backup of that, you cannot keep root.

There are stable custom ROMs, custom ROMs are meant for custom adjustments, however the stability depends on your phone, and the way you use it, you can compare AOSP vs. Stock and see the difference.

AOSP ROMs doesn't need dm verity, well, at least not if the developer did not mention the encryption part.
[Sprint Samsung Galaxy S7 Questions & Answers] CitizenSmith:
Some of the roms I have looked at mention external touch buttons at bottom of phone do not work or something else in the phone I'm just reading their comments.

I understand about the stock & custom rom's now that's not my problem at least not at the moment as I am miles away from choosing a rom! as I can't even get out the starting gate!. I can not get TWRP on my phone as the only way I can see to get it on a unrooted! phone is to use Odin but as I said Odin doesn't work at least not for me it does not see my phone. I would love to take a back up using twrp but that won't happen until I find a way to get TWRP on a unrooted phone. what crazy paradox is this!. you can't root phone without twrp installed and twrp won't install on a unrooted phone!. that makes perfect sense.
[Sprint Samsung Galaxy S7 Questions & Answers] Mohamedkam000:
Does your phone allow MTP communication? I mean can you transfer files when the phone is turned on?

Does the phone show any notification about a usb connection?

If not, then you have probably a bad USB cable, at least, or you have a hardware issue that can go as deep as a burned charging port.

If yes, then either your USB cable is not as fast as the phone requires, or you haven't installed the Samsung USB Drivers on your PC.

Unfortunately, you cannot root your device without PC, at least not since Lollipop.
[Sprint Samsung Galaxy S7 Questions & Answers] mooms:
Which version of Odin are you using ?

Use this version (latest): Odin v3.14.4

Which version of the Samsung USB drivers are you using ?

Use this version (latest): https://developer.samsung.com/mobile/android-usb-driver.html
[Sprint Samsung Galaxy S7 Questions & Answers] CitizenSmith:
Hi

Yes I can transfer files.

Yes phone asks to allow or block file transfer and it ohone shows up in Devices and Drives list and I can access the phone directory and shows up as Samsung s7 icon.

I will try another USB lead but the one I'm using is new and wasn't cheap but still a possibility I have had leads that weren't suitable for other things I was trying so it is worth a try.

Thanks
[Sprint Samsung Galaxy S7 Questions & Answers] CitizenSmith:
When I downloaded Odin this was latest one Odin3_v3.13.1 though I have doubts that one version update will fix this issue as I did not see many if any people having my issue so they all used Odin and I believe theirs are fine even with older versions! but as I said Mohamedkam it's worth a try I will down load that version and give it a try.

As for the Samsung usb driver I believe that is where I got mine

SAMSUNG_USB_Driver_for_Mobile_Phones no version visible under properties on file version 1.7.23.0.

The USB connection seems to be fine I have uninstalled then re-download and reinstalled a couple of times.

I can transfer files no problem it shows up as Galaxy S7 Icon with card and phone drive inside.

I'll update shortly thank you.

Update:

I just went to try new Odin and whilst checking my phone have seen I have Offical TWRP app installed? I have no clue as to how that's got in there! as Odin did not show phone so I could select nothing!.

In the phone I open app and if i select backup existing recovery it opens and Select Folder tab and under that Selected Folder: /sdcard Filename: Recovery .img and at the bottom of screen Root access required.

I just hope it's installed correctly!. it is showing in playstore my apps as well just to confirm. if this is now installed what should I do next Now not sure what tutorial to start following.

I am just going to try the new odin and see if it picks up the phone back soon.
[Sprint Samsung Galaxy S7 Questions & Answers] CitizenSmith:
OK Seem that it now shows up in the new Odin. at least I think it has! in the log window I see this: <ID:0/004> Added!!

I didn't see that before.

Would be grateful if you could tell me how to proceed from here!
[Sprint Samsung Galaxy S7 Questions & Answers] mooms:
Correct, you don't need he latst version of Odin or the Samsung drivers, bit it was just to be sure.

You need to be in download mode, but before, you must have checked OEM unlock & USB debug in developer options (mandatory).

I've written a tutorial with images here (in French):

Samsung Galaxy S7 (edge) - Mangez un Oreo! [Topic Unique] - Page : 487 - Téléphone Android - Technologies Mobiles - FORUM HardWare.fr
[Sprint Samsung Galaxy S7 Questions & Answers] CitizenSmith:
As I said the older version did not show any kind of data what's so ever and the phone was in download mode. phone displayed "Downloading" which I believe it says that even if it's not doing anything! so a tutorial explained. I think it must have installed the Official TWRP app even though phone did not show up in Odin everything was blank however when I installed the new version of Odin like you suggested it then showed up as <ID:0/004> Added!!. so your suggestion work thanks for that and I did enable OEM unlock & USB debug I did long time ago.

I would check out your tutorial but unfortunately I don't speak French and translating instructions is too risky but thank you for the offer but I'll carry on look around still undecided on what custom rom to go for as I said some comments point out small issues and the developers also state certain things are not working so that is making it hard to consider one if you know what I mean.

Again Thank you for your input very much appreciated.
[Sprint Samsung Galaxy S7 Questions & Answers] Mohamedkam000:
Take a note that, when you flash TWRP, you have to boot immediately to the recovery, so as to enforce its existence, cause I remember they phone has an original recovery backed up somewhere, and gets triggered when you reboot directly to system instead of the unofficial binary.

I advise you to watch guides on YouTube, it's more .. understandable.

Yer I read that but I've ended up with TWRP installed and did not do that process because I was unaware it installed until it showed up.

As I said I'll just keep looking for now I know I'll find one that works for me from start to finish.

and I've been checking youtube but wouldn't want to use any links their providing but it may help familurise myself with the whole process if i watch enough of them.

Thanks again for your help.

Hi Mooms

I will check that out many thanks. I wonder if you could help me here. I am in the middle of the rooting process but have hit a snag. again!

I have now installed TWRP successfully then no-verity-opt-encrypt-3.1 all went fine and I'm at point of flashing Magisk but have an issue when I swipe to flash is gives me a error in red saying "invalid zip file format !"

I downloaded it from github here.

I click on "code" tab and then "download zip" and I placed that in a download folder on my sd card when I select it I get the above error any ideas as to why I am getting this am I downloaded the correct file?

thanks for any assistance you could give.

[OnePlus 8 Pro Questions & Answers] bassamanator:
When I try to enable wifi (or bluetooth), it says 'Turning on...' underneath the icon but the process never succeeds.

Note:

-Under About > Status I see no MAC address for Wifi or Bluetooth.

-Phone is not rooted.

-Bootloader is unlocked.

-No custom recovery.

-Airplane mode is off.

-I am able to access the internet when I put in my SIM card and use my cellular data.

-EDIT: Model is listed as IN2025. The Build number is Oxygen OS 11.0.2.2.IN11AA.

-EDIT: I keep my SIM out of this phone (it's in my fully working phone). Can insert if need be.

My attempts to solve this issue (none have worked):

-I updated to OxygenOS 11.

-I booted into recovery and wiped everything, including cache. I also did a System Reset.

-I went to Settings > System > Reset Wifi, mobile and Bluetooth. I also did Erase all data (factory reset) in the same place.

Is there anything else left to try? Is there a way to flash the modem image maybe, I remember having to do that with my Nexus 4 many years ago.

Thanks!
[OnePlus 8 Pro Questions & Answers] blackhawk:
A factory reset never finds the root cause. A virus or an old load are the only reasons to use it otherwise find the root cause. Usually a bad setting. If it's software caused the solution is right in front of you.

Network reset, worth a shot.

Clear system cache, can't hurt.

Clear data in sim card tool kit apk.

Both are probably redundant since you already did a hard reset, but try anyway.

Otherwise...

Bad sim card (try reseating it or replace otherwise) , corrupted firmware, or defective hardware.
[OnePlus 8 Pro Questions & Answers] dlads:
Which phone do you have? I've seen this when a user has had a Chinese version and converted to global then when they updated to 11 it all went wrong.

If you're not using a converted Chinese phone then it could very well be your boot image. Extract it using payload then flash it.

If not that then MSM restore your current firmware.
[OnePlus 8 Pro Questions & Answers] bassamanator:
Sorry, what is **MSM** restore?

Under About phone the Model is listed as IN2025. The Build number is Oxygen OS 11.0.2.2.IN11AA.

So I extracted all the images(?) using payload and very foolishly decided to

fastboot flash modem modem.img

The phone doesn't boot up anymore/remains stuck in loading phase (spinner...). I did a

fastboot flash boot boot.img

+ wipe + factory reset but still stuck in loading phase.

Any ideas as to how I can fix my mistake?

I appreciate all your help guys.
[OnePlus 8 Pro Questions & Answers] dlads:
Ah yea that's not good. 2025 AFAIK is global mainly sold in the US.

The MSM tool is in discussion I believe and it's a tool you use to restore your phone using EDL mode, to get to EDL.

Power off your phone.

Connect it to your computer (if it turns on again turn it back off)

Then open up the MSM tool and press and hold volume up and down

Your computer will recognise the the device and at this point you should start the process as it will try again to reboot shortly after without any input from you.

This is the thread you need.

Bare in mind this will relock your bootloader but it's easy to get that back unlocked.

Any questions regarding the tool just ask in the thread.

(you shouldn't need to providing you download the right one)

Download the latest firmware within the tool. If you get stuck don't just guess, ask someone.

So I've managed to unbrick the phone using that tool. Thanks.

I'm going to install the latest oxygenos again, extract the boot.img from that zip, and flash it again as per your recommendation.

So I flashed OnePlus8ProOxygen_15.O.32_OTA_0320. No wifi. I extracted the boot.img and then flashed it via fastboot. Still no wifi.

I guess this is a hardware problem?
[OnePlus 8 Pro Questions & Answers] blackhawk:

[OnePlus 8 Pro Questions & Answers] bassamanator:
No bluetooth either. Same exact issue as with the Wifi, it says Turning on... then it doesn't.
[OnePlus 8 Pro Questions & Answers] blackhawk:
How/when did it start? Anything happen to the phone?
[OnePlus 8 Pro Questions & Answers] dlads:
So if you've used that tool then it'll have relocked your bootloader.

Did you unlock it again? AFAIK you can't flash another boot image unless you unlock it again.

The only other thing i can recommend (if you really don't want to RMA)

Would be to downgrade to 10 but in all fairness that really shouldn't even be an option at this point, you've flashed a clean OS back as oxygen would have, you've updated via the official OTA route.

No I think it's time to contact OnePlus for an RMA.

Unless someone else had seen this issue personally I haven't.

Had you rooted in the past btw? Flashed many magisk modules??

I find it highly unlikely that they could survive this but you could potentially try the magisk removal command, can never remember it it's in my payload dumper guide.

If no one else chimes in I'd say it's an RMA, I've not seen it before, it's strange.

Also (and please don't put it on here) but is your IMEI missing too?

This could be your EFS partition if so.

Edit: found this super old thread for the OnePlus one, same issue.

I think this is fixable, potentially remotely from OnePlus and or anyone else who has access to the updated tool, might be worth mentioning in the MSM thread if you haven't already.

PS: don't follow the guide in the link btw it's for the 1+1 lol, in just putting it here as a reference

I got the phone used right before Christmas. It still had the protective plastic on it until I removed it today. It really is in mint condition (or looks to be). I've been away and finally got around to moving things over from my old oneplus 3T.

It's certainly possible that I bought a lemon but at this point I'd like to just fix it if I can.
[OnePlus 8 Pro Questions & Answers] dlads:
I think it's fixable now I really do

From what I've been reading I think it's a mixture of partitions that have been borked z namely the EFS and potentially the persist.img partition if the same position structure exists that did back in the day.

With that in mind are you able to use your fingerprint? I only ask as persist is linked to it so if that's not working then we may have a correlation between problems.

If it is then it's a ? Over the theory.

I'll keep reading but from what I can gather it seems that EFS and persist at least were linked, can't be sure if they are this point.

Have a look at that link I sent see if anything raises a flag for you, bare in mind it's for an older device
[OnePlus 8 Pro Questions & Answers] bassamanator:
Yes I had to oem unlock again.

As far as I know the phone was not rooted but it's a used phone. Superficially it's in mint condition, I just removed the plastic film just earlier. I'll post in the MSM thread and checkout the new one you posted.

EDIT: the phone has 2 IMEI numbers.
[OnePlus 8 Pro Questions & Answers] dlads:
I've already posted in the MSM thread for you.

What about your fingerprint? Is that still working?
[OnePlus 8 Pro Questions & Answers] bassamanator:
So I've never registered my fingerprint on a smartphone, ever, but I thought I would register one of my toes just to figure this thing out. When I get to the Fingerprint Setup screen I get the following error: Enrollment was not completed. Fingerprint registration error, please try again.

Does this help narrow down the issue?
[OnePlus 8 Pro Questions & Answers] dlads:
Yea for me it does, it shows there's a correlation between the persist problem and the EFS problem and a direct connection to your IMEI or Mac address issue.

With this in mind I would recommend the persist.img fix thread..

Getting that working may be key to solving the Mac / IMEI problem.

At this point nothing is going to hurt.

[OnePlus 8 Pro Questions & Answers] dlads:
Ok don't do the EFS fix you do not have an EFS back up.

Give this a shot

go to data/misc/wifi (required root)

-backup file wpa_supplicant.conf in this folder which contains usename and password wifi

- delete all file in this folder

- turn on wifi ( if you careful, you can reboot )

- now you can connect to wifi

- recovery file wpa_supplicant.conf

And with that I'm going to sleep. Knackered.

Well check in on you tomorrow
[OnePlus 8 Pro Questions & Answers] dlads:
The aforementioned fix should fix WiFi and BT then go through the persist fix and you should be ok.

If your IMEI is functional then definitely back up your EFS partition. Do not remove the modem using the guide commands you wrote

You're going to need root for all of this
[OnePlus 8 Pro Questions & Answers] bassamanator:
So after 6 or so attempts, I was able to root my phone. I have Oxygen OS 11.0.2.2 installed, rooted.

I created /data/misc/wifi/wpa_supplicant/wpa_supplicant.conf (which I've done before on my Raspberry Pi). It was an interesting process because I didn't have access to an editor. One thing to note is that I didn't include the first line of wpa_supplicant.conf from my Raspberry Pi because it doesn't 'work' for android I think.

#I did not include the following line:
#ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
country=CA
network={
ssid=XXX
psk=XXX
}

Of course this did not work (wifi/bluetooth still not turning on) because either the wpa_supplicant.conf was incomplete (because of the first line that I ommitted) or because then this problem would have been too easy to solve.

I have backed up my persist.img and am ready to try the fix persist guide if you think that's what I should do next.

Thanks again, you guidance and help is much appreciated.
