Flashing Custom Roms on Oneplus6T - OnePlus 6T Questions & Answers

hi guys,
Ive been using stock rom since i purchased this phone.
Thinking of flashing some custom roms. but i have few questions in my mind. Hope you guys can advice me on that.
- Can i use a custom rom without Root ? My interntion is to use banking apps without any problem. Not really interested in in using Magisk to hide the root status.
- i have a manually enabled call recording on my Oneplus6T. Do i get this feature working on any custom rom ?
- I undestand that i need to unlock my bootloader to flash custom roms, so in case if i want to revert back to stock rom in future , will it break any security mechanism of the phone?
Please advise.

- Yes you can run a custom rom without root. You can even lock your bootloader with a custom ROM (WARNING, you can just lock your bootloader, it's a whole process, DO NOT just do this. Research first!). That being said, I would venture to say many banking apps would take issue with custom ROMs even if you aren't rooted. However I don't use them, so I can't say this for certain.
- Yes call recording works in (some) custom ROMs.
- Unlock your bootloader, won't harm anything. You can always go back to stock. If you want to completely go back to stock you should be able to just run the MSMTool and it should put your phone back exactly as it was out of the box. It reloads the stock software, and relocks the bootloader.

[Q] Note 4 Rooted, Then What?

I'm coming from the HTC environment and the Note 4 will be my first Samsung phone. I have a few concerns regarding root. Assuming the Note 4 can be rooted, using the Note 3 and the S5 as a precident, how does one maintain updates? With HTC, if you had root, you could flash a new ROM for software updates (newer android versions, bug fixes, carrier updates). However, to update firmware, like updated radios, you needed S-Off.
Please help explain. With the Note 4, what will we need in order to do the following, and what is the likelyhood each of the following will be possible:
1) Obtain Root to run apps requiring root (Titanium, adblocker, WIFI tether...)
2) Install custom recovery
3) Flash custom ROMs
4) maintain a phone with updated and current Firmware and Radios.
Otherwise, what do people do who root there phone on day 1? Do they go 1-2 years with the phone without updating firmware?
Thank you
you can update samsung software with no issues. Assuming they'll keep it like the Note 2, there under the settings>update, there are different tabs, and one is Samsung.
Modems and other such updates, you'll just need to wait a day or two for someone to upload the newer OTA with root. Sometimes, some of the root tools, like SuperUser, will have OTA survivor mode, but they're not guaranteed to worked.
End of the day, it's not anything you're not already use to
Thanks for the response. So if the bootloader is NOT able to be unlocked, what will we be missing out on then? If the bootloader IS locked and there is no way around it, we can still root, flash ROMS, and update radios/firmware?
we can only go by the past to predict the future, but in US ATT Note 3 had locked bootloader, T-mobile loader was unlocked, so it was up to the carrier, but I believe both had way to root. One problem with Samsung was Knox software, which once triggered by root or loading custom firmware couldn't be reset back to zero. Based on that flag some people claimed to be refused warranty repairs, others didn't, so who knows. One thing is that Samsung "donated" knox to Google L Android, so it may be on all Android phones in the future, but again who knows how Google will implement it. It may take a time for developers to find their way around new phone, so if you have concerns, wait a little until all is clear, for now we can only guess. My Note 3 is rooted, "official" with Knox flag 0, but I had to wait for proper methods to be developed and every time I update I need to re root (and make some other changes) again. There could be developer model also with everything open, who knows.
Thanks for the response.
I just need to clarify what can be done on a rooted Samsung device vs what can be done with a rooted AND unlocked Samsung device.
Am I correct:
Rooted Only:
-superuser
-can run root required apps (Titanium, Wifi Tether)
-can flash custom ROM but must be stock based only, and must be on stock kernel
-can NOT install CM or TWRP custom recovery
-can update firmware and radios but must OTA and then re-root
you cant flash a rom with stock recovery
if no bootloader unlock, and no custom recovery, then no rom flashing..

As stated above, this not correct. You'll able to flash the stock firm via Odin. In fact, you'll be able to get the tar file from Samsung if you wanted.

I haven't used it in awhile, but I believe you still need a custom recovery to use Mobile Odin, don't you?
i want root mostly for four reasons:
Disable logging
Multi window enable more apps
Make one hand mode background black
because its mine and i can...
But I also need it rooted without tripping knox (for work purposes..)

Unlock Samsung Note 3 Vodafone UK

Hello,
I tried several things to unlock my phone, unfortunately, unsuccessfuly.
I use the Sim Unlock code provided by Vodafone : no chance
I rooted the phone and tried Region Lock Away or the Sim Unlock Samsung app, no chance either. I think that the phone is rooted properly but everytime an app request root access, it times out.
I am running out of (good) idea. Any pointer would be very helpful!
Thanks
David
Are you trying all of these thing while running a stock ROM?
I had the same problem with t-mobile in America. It was because I was using a custom rom. I backed up my phone, installed a "stock rooted rom" and was then unable to unlock the sim. Then I used my backup to restore my phone back to the custom rom. Good luck.
I used Odin 3.04 then I install CWM recovery on it.
I tried to unlock the phone before rooting it but it didn't work which is why I try to root it, nothing works... What is a stock rom ? I only want to sim unlock it really, i dont need / want it rooted specifically
What is a stock rom
Stock as in standard firmware as supplied by Samsung .
This all assumes you have a custom rom installed.
You can return your phone to stock (maybe) but it's kind of a pain.
It seems easier to flash a stock rooted rom, which is similar enough to stock to fix your problem.
Google "stock rooted rom vodafone note 3" or maybe just N9005XXUGBOA5_N9005VFGGBOA2 seems to be what you are looking for {actually that appears to be the stock file that you can flash with odin and mostly re-stock your phone.... not sure if it will accomplish what you need}.

Need Instructions to avoid almost bricking again

Hi guys. I very narrowly (somehow) managed to recover from almost bricking my phone.
I successfully S-Off'd my phone, and previously successfully installed TWRP. I tried to install this ROM:
https://forum.xda-developers.com/ve...m-perfumewl-m60-dev-edition-unlocked-t3442969
When I tried the to flash the ZIP for firmware and for the ROM, the firmware wouldn't install. I tried some other stuff and basically almost bricked my phone. Some how got it to suddenly start being able to use the htc_fastboot commands (????????) and was able to start installing the zip for stock... but it ran an error, I ran it again and it froze... then I forced my phone to reboot and somehow I'm back to having a stock system. No clue what I did.
My question is, can I take a software update on my phone normally (to 7.0) , and then install just that ROM? Or so I need to flash the firmware separately with a command line command? I just don't want to give myself another heart attack tonight. Current firmware version is 1.82.605.6, not rooted, don't believe my recovery is TWRP right now (but I know how to install that one).
I'm just looking for root access and the ability to remove pre-installed Verizon crap (VZW Messager, My Verizon, etc). Thanks guys.

I recommend you install this one instead:
https://forum.xda-developers.com/ve...m-1-85-605-9-aroma-root-root-debloat-t3529732
Follow instructions in OP...or:
1)fastboot flash FW w/o Boot w/ TWRP (htc_fastboot oem rebootRUU, fastboot flash zip...)
2)htc_fastboot reboot-bootloader
3) Finally, go into recovery-- backup and flash ROM (choose root w/ Magisk and debloat)
Thanks, I figured out why it wasn't working before. Used official TWRP, thats why it wasn't working. Wouldn't have thought that'd made that much of a difference.
New problem though; something I really would like to use the Google versions of contacts and dialers. Trying to flash those just made my phone app unusable. So I turned to LineageOS but it REFUSES to boot. Hangs on their little vertical line with a moving circle. Found out AOSP roms don't like VZW firmware? Flashed global firmware, updated through WiFi as much as possible, and then ran into issues with radio, even though I flashed the VZW one. So I reverted those changes, am going through with what you said above to have a working phone (after not having one all day), but any advice on getting Google dialer and contacts? I'd like to use LineageOS but I couldn't get it work at all.

You've got to read OPs, search threads, etc. Some ROMs work w/ our phone, and some do not. Check out the latest versions of ice and leedroid. Your most likely want to grab the SVN versions is the official versions may not yet support Verizon N firmware

I have been doing a lot of searching, but I've found so many different, conflicting sources of information. For example, one website told me to install LineageOS, was to be on latest Verizon OTA and just normally flash it; that obviously didn't work.
So from what I can see, our choices are Viper, Ice, LeeDroid, NuSense and the one you linked. I'm going to try out LeeDroid... out of curiousity, is there any reason, for example, LeeDroid or Ice haven't posted in this Verizon section with links to their ROMs?
*Edit Two* Dialer wouldn't work out of the "box" so to speak, so I had to go to Phone settings at the bottom, there is a menu called Calling Accounts. Had to go there and tap Receive Incoming Calls... why is that disabled in the first place..? But that seems to be an issue going even as far back as the Nexus 5. But that's how you find the option in the HTC 10 for anyone who comes across this issue too...
Not sure why your having issues with the flashing. Are you doing a full wipe? Not just factory reset. Going from stock to lineage requires a complete format of internal SD card. On the stock roms, most will ask if you are still on marshmallow firmware & are working fine. Again, we need more info on what firmware version your on, version of twrp& how your wiping your device. Most AOSP roms work, but no advanced calling
LOS ROMs will work without issue IF you have flashed the US unlocked firmware at some point in time. This is the only information that we have found from a VzW device with LOS booting and VzW device without. We started a thread awhile ago and is the only known method we currently know of to get LOS booting. Also works for Sprint users.

T-Mobile Carrier Unlock Question

It looks like the T-Mobile v20 is carrier unlocked via the Device Unlock app. That assumes the phone is eligible for an unlock, which mine is. The problem is that I'm running a custom ROM, and the Device Unlock app doesn't appear to work on anything other than a stock load. That's even running Magisk and confirming that everything is "hidden". I base this assumption only on some stuff I found while searching the forums.
So the obvious solution is to flash back to stock. If that's the only way to do it, fine. It's a pain but I'll do it. Does anyone know if there is an alternative bit of trickery so that it can be done on custom ROMs?
It's not so much the backup/wipe/load/unlock/wipe/restore process I'm trying to avoid. I do that all the time when I want to play with other ROMs. It's the bootloader/recowvery stuff, and plus it looks like the stock image isn't just a standard zip.
I appreciate any input, even if it's just to confirm I have to go back to stock.
as far as I know the bootloader has to be locked for the app to work... I'm always on stock and despite removing root the app would just keep trying to contact the server. it wasn't until I locked the bootloader that the app went through and contacted the server

Lock bootloader after root and ROM custom

Hello, guys.
Recently, i wanted to install the fulmics ROM (which is awesome) on my LG G6 H870.
So, i've done it, the bootloader has been unlocked, it's rooted right now, and i've got the Fulmics ROM which works perfectly.
But, i still have a question. When i boot up my phone, i've got this message :
"Your device software cannot be checked for corruption. Lock the bootloader. etc..."
This isn't a problem, because i can boot up my phone.
But i just wanted to know if i can remove this message, and how ?
Thank you all for your answers and your help.
This is normal and cannot remove that message. Just ignore it, how many times do you actually reboot for it to be an issue? If you ever need send phone off for repair just flash stock and lock bootloader again.
normal bro don't worry

dude I've got a question: if you wanted to get your bank's app working again in a custom rom/recovery is it possible to relock the bootloader in order to get older compatibility (mario kart, spotify options, bancoestado) but in a system like PA Quartz 3 or PixelExperience ? Or bootloader wont boot locked another system than LG?
I seriously need those apps but also need Android 10
