OnePlus 2 OTA updates with unlocked bootloader question. - OnePlus 2 Q&A, Help & Troubleshooting

Hello fellas. I intend to sell my OP2 as i have purchased another device. I had been rooted with custom roms for the past year. Today i flashed the latest stock rom (OOS 3.5.8) and flashed back to stock recovery. I made sure everything works but i do not know if i should lock the bootloader again. My question is: Will the OTA updates work normally with the bootloader unlocked? Or should i lock it again to make sure?

Yes you'll get OTAs with unlocked bootloader

Good to hear, wouldn't want to sell a phone that wont recieve working OTAs lol. Thanks for your reply.

unlocked bootloader effects on ota installation or not

last time i unlocked my phone and installed another rom, but i dont like that. so i thought to revert to stock rom.
then i flashed stock cm12.1 , then again boot loader was locked.
then i unlocked bootloader only, so as if in any case i need to recover my data by rooting.
today i read a post on yuplaygod forums that they will release an ota soon,
i want to ask is there any problem if i install the OTA, any chances of device bricking or something else, because bootloader is unlocked, but phone is not rooted , everything else is true stock.
I sent my phone to service center when it has 5.1.1 of cyanogen mod and I don't know how they flash 5.0.2 of cyanogen mod it doesn't install any ota updates so I rooted and manually installed 5.1.1 officially by YU but the problem remains same. Can anybody help me.

HTC M8 The Legend and how to Upgrade!

Hello guys i decide to open this new thread to ask a few question to clear this out for myself since it last before long time i almost forgot everything.
I bought my m8 imideately after the release and till now NO other device grab my attention in design hardware Sound and etc. So after years of use i drop it several times u know... and i start to have problems sometimes losing signal sometimes when making a call its a bad ass people dont hear my sometimes i dont hear them or the call just drops etc also several sratches.
Anyway i decide to get A NEW M8 second hand in fully working condition in perfect shape without any sings of use. becuase i really love this device.
The previous one was HTCdevs unlocked then Rooted then S OFF with firewater and right now is still runing the latest S.Team ROM
The "New One" that i bought is with Stock Software, Firmware S-ON all is super stock.
As far as i read i cannot S OFF it anymore like before i did with my previous M8 with firewater.
What i can do in order to be able to flash a custum Firmware?
I don`t know what is best for the phone... because i did update my old device from day 1st till now with every new release of Android or Firmware.
Like i say the new one is super clean Stock
Can i jump directly to the latest Android 6 Custum ROM i want?
what i shold do 1st?
HTCdev then ROT and S-OFF?
if i change the motherboard of with the old one that is fully unlocked this will grand me all benefits of S OFF?
For example i want to go all the way from Pure Stock Android 5 lets says to latest Custum S.Team ROM
what i should do best?!
Thank you in advance
I'll answer some of these questions
1. Firewater no longer works, you have to use sunshine now to s-off.
2. To get the newest firmware just update to newest version through OTA, make sure you got locked bootloader. After that you can do whatever you want - unlock bootloader, flash roms, s-off, etc.
If you have a few bucks to spend, you can S-Off your device, but in my case, I have this phone 3 years already and still S-On and have flashed numerous custom ROM's already and I'm happy with it. ?

As long as the phone is currently on Marshmallow, then yes just unlock bootloader, flash TWRP 3.1, and flash the desired ROM.

Unless you are really skilled with that sort of thing, I'd leave it well enough alone. I've seen a lot go wrong with taking the phone apart. So you risk ruining a brand new phone, for no good reason. Spend the money for sunshine, if you need s-off for a specific reason. But you don't even need s-off for flashing ROMs, firmware, or most other mods.
I'm in the same boat. I just bought an carrier unlocked brand new M8 because.....well....I love this phone. I too have had my current M8 since release but now the charging usb port is acting up. I'm very interested in rooting my new M8. I never did my current one.. My new phone is coming with Android 4.2 I think. Should I I OTA it as soon as it comes in or unlock the bootloader etc flash TWRP before and the just flash a custom ROM?

I was rooted, unlocked bootloader with s-off. I went back to stock and got all OTAs. So, is locked bootloader necessary?

You should OTA and update to Marshmallow before unlocking the bootloader.
Especially if it comes with 4.3 (or anything before Lollipop Android 5), the firmware won't be compatible with the current ROMs, and you will be stuck with issues like no boot, no WiFi, etc. Also, the current TWRP versions will not be compatible with older firmwares.
So short story, you must update in order to flash current ROMs.

Unlocked bootloader is okay for OTA updates. However, you will need to restore a stock never rooted ROM (unrooted will work - OTA will fail) and stock recovery in order to OTA update.
Rooted ROM will cause OTA to fail. Custom recovery will cause the update to get stuck, as it expects and requires stock recovery.
Return to stock ROM and stock recovery with using this guide: https://forum.xda-developers.com/htc-one-m8/help/tutorial-how-to-stock-stock-twrp-t3086860
And to be clear, there are no updates beyond Marshmallow for this device.

I was rooted, with bootloader off, s-off with TWRP. Did not have stock recovery. Found my version of stock RUU here on XDA, thankfully, installed and received all the OTA's. Am now Android 6.0, HTC Sense 6.0 Software Number 6.12.1540.4.

Stock recoveries are posted on the guide I linked. But yes, RUU is a valid method as well to return to stock and/or update. On that note, you could have just RUU'ed up to any version, and not done any OTAs. Marshmallow RUU's for US versions (which yours is) is a slight exception, where you have to flash the 6.12.1540.4 firmware using fastboot, then you can run the 6.12.1540.4 RUU.
No need for s-off to flash a custom ROM/kernel. Just unlock via htcdev, flash twrp recovery via adb, be sure the zip of the new rom is on the internal memory/sdcard, flash it, done. I recommend leedroid + clumsy kernel or ice + clumsy(on ice keep in mind that sometimes it freeze on boot htc logo around the first few restarts, hard restart it and it should be fine, if it's not - clean only cache via twrp and it will boot normal from there on).
I received my new phone, installed the AT&T sim but when I try the OTA system update all it does is say "checking". Can I manually update via PC? What update package should I download from htc?
The phone is currently on Android 4.4.4 htc Sense 6.0 Software # 3.28.401.6

nougat

Hi all,
Noobie questions sorry.
I have a xt1625 us retail version and I'm getting prompted to take the OTA nougat update.
However, I have unlocked bootloader and TWRP installed so it fails.
1) Is the stock nougat available as a zip?
2) Is my best option to relock bootloader and go back to stock recovery, in order to take the OTA?
3)Is there a stable custom rom that is preferable?
Thanks very much
update;
I reflashed the stock firmware using fastboot and the 16 ish commands needed.
After this I took the OTA update without issues.
You can re root your phone and reinstall twrp now.

Yes. bootloader remains unlocked, so I can root later.
for now I am satisfied, stock rom isn't too bloaty

Back to stock

Hi i hope one of you more technical people can help me out. I would like to return my moto x force back to stock after running Lineage os on it because I need to sell it. I have flashed the stock MM once before in fast boot and managed to achieve this but I was unable to relock the bootloader. How can I flash the stock rom and also lock the bootloader so that the person who buys the phone gets the chance of the next OTA update for Nougat when it eventually arrives. Thanks in advance for reading.
Unlocked bootloader suppose be not a problem for OTA.
but how do i relock the bootloader properly in order to get any future update?
