So I'm still on stock, but I can't install OTA updates, which is to be expected since I have an unlocked bootloader, and TWRP. But I'm wondering if that will make an upgrade to Pie impossible without waiting for a custom ROM to come out? Or will I have to relock the bootloader to get it?
yes, if u not rooted neither using custom recovery

I just got my Arc S, and i want to check out few different custom roms. I was planing on rooting the device with Easy rooting toolkit, so the question is, how can i backup my stock rom and reflash it, if i ever need it for warranty issues? (Also maybe to get the official 4.0 update next year )
On my previous phone (HTC Desire) it was pretty easy, by restoring the Nandroid backup that i created after rooting the device. How about the Xperia? Is there something similar?
And while we are here, any suggestion for some stable custom roms for the Arc S? Thanks
If you only want to root your device, you can simply unroot the device.
But you don't really have to, when you update your device using PCC or SEUS, the root is gone.

If you decide to unlock your bootloader to flash custom kernels/ROMs, you have to relock it, when you want to update your firmware using PCC or SEUS.

And which custom ROM you like is your decision, but I'm still a CM7 fan.
I have root, if I want to return to stock ROM (without root) I can just use SEUS to update my phone and the root is gone?

If your bootloader is locked yes.
I rooted my arc with EasyRooting toolkit,
How do I know if my bootloader is locked or not?
Edit: I checked by the service info, it says
Rooting status:
Bootloader unlock allowed: No
I am guessing that means my bootloader is locked?

Yes, it is.
And if you root, it doesn't, mean you've a unlocked BL.
Btw, you can't unlock your BL using the official method.
If you still want to unlock your BL, contact Jinx13.
Is it possible to downgrade from 4.4.2 to 4.1.1 to unlock the device?
You just flash the 4.1.1 then probably have to flash your bootloader if it doesn't boot and then flash the jl2 radio
Hi, I have a custom rom, the galaxy project 4.4.2. What I need to do to unlock the phone?
Can I downgrade to a custom 4.1.2 via recovery, and apply the unlock tutorial?
Correct me if I'm wrong, It's the bootloader that has to be downgraded in order to unlock using the hidden menu. But with devices that took OTA updates 4.3 or later, downgrading bootloader will brick the phone. I'm also looking for an unlock option but no luck so far because my Note 2 has OTA 4.4.2. Does anyone have better information about this?
Hi,
I have the AT&T S3. I took the OTA update to NJ1 now. Does that mean my bootloader is now locked and won't be able to root? and install custom recovery?
The i747 (AT&T) does not and has never had a locked bootloader.

Your bootloader has been updated, but as Audit13 said, no, the bootloader is not locked. You should be aware, though, that you should not try to downgrade your bootloader to a previous version. (I.e. after some times if you attempt to return to stock ROM using ODIN, you should not install a build previous to NJ1.) Except for that, you will still be able to install a custom recovery, root and flash custom ROMs.
thanks guys much appreciated! happy new year !
I have an AT&T SGH-i747 with bootloader I747UCDLK3, modem I747UCUEMJB and running CWM 6.0.3.8. I am planning on updating the bootloader to UCUFNE4. I have already unlocked the phone. Is there anything else I should do while my bootloader is still on UCDLK3 before I take the leap to UCUFNE4? Any suggestions and advice is appreciated. Thanks.
Did you carrier unlock your phone? If not, flash back to stock 4.1.1 using Odin, sim unlock using the free method, and run OTA updates until you get to the latest KK stock ROM. You can then install a custom recovery, flash supersu, disable know, and flash custom ROMs.
Hey all,
Is it possible to relock bootloader and restore stock recovery? I have stock room with root and twrp but want to revert back to full stock. Anyone know if that is possible currently?
I'm pretty sure the only stock firmware that has been released for this device is the Chinese variant. If you're on the L24 variant like I am there is no way to get back to stock of you rooted and installed twrp unless you made your own backups.
I made my own backup from stock but would like to make sure I get any OTAs. I assume I need to get back to a locked bootloader?
Nope. I have an unlocked bootloader and I just got an OTA yesterday. Installed with no problem. The twrp is a definite reason why one wouldn't be able to install ota and I'm not 100% sure but I think that being rooted is another although I've read conflicting stories about the root part.
