[Q] Does falshing your firmware remove root?

Hi, I just flashed my firmware to JM9 and my phone where rooted before I did.
So I was wandering if my root acces where removed when I flashed the phone?
And how can I check if my phone is rooted?
EDIT:
I installed busybox which says my phone wasn't rooted. So I guees flashing firmware does remove root acces.

That's right when you flashing a new firmware, it's will cover the old things. but if you want to have a good results, before. You flashing a new firmware, you need to daily *2767*3855# refresh your phone and clear the data.

Knox or not

Dear friends,
I have a Samsung Galaxy S4 Active GT-I9295. I got it with Jellybean where in download mode I saw knox warranty void 0x0 however after updating to lollipop 5.0.1 it dissapear and I saw the following in Download Mode:
Odin Mode
Product Name: GT-I9295
Current Binary: Samsung Official
System Status: Official
CSB-Config-LSB: 0x30
Secure Download: Enable
Write Protection: Enable
eMMC Burst Mode enabled
What does that mean that I no more have Knox Security installed and I can flash custom recovery without tripping knox or it is just hidden?
P.S In Apps Manager i see that KMLS Agent and other related apk for knox is installed.
Thanks in advance for your help.

Can someone help please?

Not much investigation done on i9295 about Knox. Since approx 95% hardware is identical to i9505 the findings about that device is best guess. Links and knowledge gathered here: http://forum.xda-developers.com/showthread.php?p=56955843
Despite so called Knox free ROMs where all related apps and libs are removed, to my understanding and supported by many posts in i9505 thread, this is not Knox-free when bootloader still has Knox features. Downgrade bootloader only or flash Jellybean stock ROM on top of this so called Knox-free ROM or any Knox bootloader will most likely trip knox 0x1.
Own experience:
KitKat NE4 - flashed CF-Auto-root for I9505 - CWM 6035 - *6047 - *6051 - CM11 (several official) - TWRP 2840 - stock Lolipop OB4.
NEVER downgraded bootloader (or felt urge to mess with modem /non-hlos.bin relationship)
Knox 0x0 all the time and still reports 0x0 when checked by app PHONE INFO *Samsung*
Can confirm identical Download mode text for OB4.
READ tips in my thread and learn how to flash custom recovery 1st time correct and later perhaps zip install SuperSU 2.46 (free) to gain root.
Rather comprehensive guide provided by @ANX13TY http://forum.xda-developers.com/showthread.php?p=59326914 still you ask how to throw phone into towel root? Towel root is insecure kernel. Fastest way isn't necessary best way.
CF-Auto-root 442 NH2 might work as well when rooted 442 kernel run in stock recovery...

Root and unlock question.

Hello,
I would like to root my phone, but do I also have to unlock the bootloader and install a custom recovery? I don't want to install custom roms, and I want to be able to install updates from Google. The phone is also unlocked, but I'm not sure if unlocking the bootloader is a totally different thing. Basically I just want to root to get features such as the notification light and install exposed.

NOTE: This will only work on lollipop, for M preview you need a modified kernel, otherwise it won't boot!
If you only need root then use Chainfire's CF-Auto-Root (https://download.chainfire.eu/628/CF-Root/CF-Auto-Root/CF-Auto-Root-shamu-shamu-nexus6.zip).
To install root, you need to unlock the bootloader (CF-Auto-Root will do it for you if it's locked), but it will wipe you entire phone, and do a factory reset. So backup everything before you root it.
This will leave your stock recovery unchanged.

Thank you. This is exactly what I wanted.

You might want to consider installing twrp also, at least you can do a backup before you start messing around with stuff. Just rooting the phone will allow you to do everything you need /want but if you change something that makes things go south you have no reference point to return to.

Also, just to clarify: You will NOT be able to recieve OTA updates after rooting your phone. Rooting, using custom recovery, custom kernel or anything at all that tampers with the system prevents OTA updates from installing.
If any of the above has occured, the only way to be able to start updating through OTA again is to flash a factory image (or at least relevant parts of one).
Unlocking the bootloader will not affect the ability to update through OTA.

A few Questions from a Noobie

Hi, im new to Note 5 Dev. and been out of the loop since it was released. i had a Sony Xperia play and a Galaxy s3 before and know how to do the basic stuff to do custom roms and flash stuff etc. to those Phones. But a Note 5 is different, running on Lollipop, having EFS partition stuff and OEM unlock Stuff. i just want to ask a few questions to make sure i don't do something stupid (i already did some of the research for answers on some of this for a few days now and some are Informative and Awesome, but a little outdated) so tnx in advance kind People :fingers-crossed:
My Device: SM-N920C (UAE)
Android Ver: 5.1.1 (Lollipop) Stock
Questions:
1.) Can i Revert back to 5.1.1 (lollipop) stock/ [Downgrade] , IF i decided to update to Nougat Stock?? (just curious ) and if yes, can you kindly link me to a process? if not, then that's fine too :laugh:
2.) Do you have to Enable OEM unlock if Updating Stock (in my case Nougat)??
I red somewhere on Magisk thread here on XDA that it can Grant Root Access to 5.0+ . If so, installing TWRP and Flashing Magisk on 5.1.1 involves Enabling USB Debugging and OEM Unlock.
3.) Do i have to Enable OEM Unlock Forever now? cause i saw some threads says that if you disable it, you will have a bootloop or a soft brick and will have to Flash Stock again and repeat. (don't really have a problem with it being Enabled, but the other people in Tutorials , Vid. Tutorials and Thread Posts just mentions "Enable it". And never really says after the process is done u can Disable it and stuff.), just want to have that information, cause i Understand that OEM is a LOCK that Even if someone steals your phone and has a lock in it. they can't just Flash a Stock Rom on it to Unlock it. [great feature] :fingers-crossed:
4.) if i have a Custom Recovery and Rooted my phone ver. 5.1.1 successfully, can i still Unroot it and go back to Stock 5.1.1?? also applies to other Versions of android. EX. nougat Stock then i root it, will i still unroot it and go back to stock?
5.) Do you need to be in a Specific Version of android to use the Custom Roms?? i mean i'm in android 5.1.1 [if rooted], can i flash a Nougat Custom Rom or a s8 port etc.?? or do i need to be in Stock Nougat > Root it > then flash Custom Nougat Roms?
That is all, Sorry if all the Questions are Freakin Long Shahaha, i just want to be specific so all the people who are also newbies can understand the questions and have answers. Tnx again for the people who have the patience to read and answer these questions. :highfive:

Click to collapse
1)If you flash stock 7.0 on your device if available then its hard to revert to back to stock 5.1.1 as there is thread in Question&Answers section about downgrading from 6.0.1 to 5.1.1 but many are unsuccessful(I have successfully downgraded from 7.0 to 6.0.1 but Cant confirm about 5.1.1 as google has changed many security policies in updates versions like 6.0.1 or 7.0 which will block your bootloader to downgrade easily/Issue you will face like lossing of baseband or corrupt imei which will block you from receiving network signal)
2)Yes its very important to enable Oem unlock and usb debugging while flashing any stock firmware using odin to avoid DM-Verity/SW Check Fail/Custom Binary blocked by FRP like issues which are hard to solve enough OR you will might hard brick your device which will be difficult to make it live again( AFAIK to flash TWRP or Any root access using odin there is instruction to enable Oem Unlock before flashing always remember it as a essential step before flashing anything using odin)
3)Yes once you enable Oem unlock for purpose of modification of your device, it needs to be unlocked or even its enabled by default to overcome reported issue like infinite bootloop or Many i mentioned in my 2nd Post And Oem unlock allows your bootloader to be customised by flashing mods or roms which is by default locked so that you could not easily modify your device as well as to avoid further modification issues
4)If you choose to stay at 5.1.1 and rooted your device with installed TWRP then yes you can unroot it by flashing 5.1.1 using odin( In case your on 6.0.1 or Even on 7.0 you can unroot your device with the same process but here to remind you that you need to flash stock 6.0.1 or 7.0 respectively version on which you rooted your device So if you will try to unroot it by flashing 5.1.1 again while your on 7.0 rooted device then again here downgrade issue which will probably give you mentioned error as a result)
5)To use custom nougat based roms or any S8+ port based on 7.0 you should atleast upgrade your bootloader and modem to 6.0.1( If your rooted on 5.1.1 and try installing nougat roms then your device will not boot as your using old bootloader, so upgrade bootloader or modem either to 6.0.1 or you can update whole system to 7.0>root>install TWRP>flash custom nougat based roms or s8+ ports afterall choice is your as if you want to upgrade only BL and Modem to 6.0.1 or want to upgrade system with BL and Modem to 7.0, i will mention here is BL and Modem for 7.0 are also available to flash you can find those on dr.ketan rom n10 installation instruction section in Samsung galaxy note 5>Android development>Dr.ketan Rom N10 instead of whole system update but Flashing Stock full firmware is always recommended for good reception and avoid glitches)
I think i have tried to fulfil all of your queries as far possible by myself

Too bad about the answer to the 3rd question, that feature would've been nice to have. but oh well. shahahaha
~Ooh!! i have a follow up question regarding your Answer to the 4th question. Can i also flash other Countries Stock firmware?? for example: mine is Stock 5.1.1 [UAE] can i flash Stock 5.1.1 [USA] or other Country variants?? [of course unlocked bootloader] , i searched again here for people who did that and for some reason they encounter Errors and Unable to revert back to their Original Stock Firmwares.
@AssassinCreed Thank you. yup, clear cut answers. Thank you!! :victory: :victory:

XT1805 Camera2 API

Is there a way to enable the camera2 API on the moto g5s plus xt1805 version? The methods I've found that edit the build.prop file require root. I've tried one-click root methods but all have failed. I want to avoid a custom recovery or a custom rom.
Any replies appreciated

You cannot avoid rooting your phone if you want to enable cam2api, therefore you must unlock your bootloader and get a custom recovery in case you want this. DO NOT TRY ONE CLICK METHODS, these don't work for this phone, not a single one of them. Also don't be afraid of rooting your phone, if you follow every step correctly you won't have any trouble. You also don't need to use a custom rom, you can root stock and keep it unmodified if you wish, but you will still lose warranty and OTA updates with a custom recovery.
