I was just wondering if I relock my bootloader does that wipe the phone like the unlocking does?
What I want to try and do is unlock it, customer recovery and backup, remove hidden apn, put back stock recovery, relock.
That way I can tether again without issue and also get updates.
Only reason I would like to stay on stock software is that there is not really many roms and no 4.1 roms that have wifi calling.
I use that alot.
Has anyone relocked there bootloader at all? LOL!
No, running fastboot oem lock won't wipe your device... At least I don't believe it did on my Raider.

cool beans
because I want to try this method for removing the locked APNs on the device and see if it works.
Also just need to find the original recovery to flash on the phone too.

Just a quick question.
Say 2.3.4 stock ROM comes out. If I flash it via recovery, would I have to flash the custom kernel via recovery as well, this time without whole rooting process or would I have to start from unlocking bootloader steps?
The custom kernel might be too old or incompatible. When you upgrade you will need to go through the rooting steps again, you will most definitely lose root, I'm not sure if the bootloader relocks though, if it does just fastboot OEM unlock again, you can do that in no time

Yes you can but you must be rooted

My question is, if you relock the bootloader on ns4g after unlocking and rooting, will you loose the root or the ability to flash any custom roms or mods?

No. You can still flash anything via custom recovery.
You will, however, lose the ability to flash a custom recovery if it is overwritten via fastboot. If you have root access you can still use the flash_image binary from the device or flash via Rom Manager. If you lose root and recovery though you will have to unlock again.

This is a dev phone, so you can lock and unlock the bootloader as you please. You will not be able to switch the recovery with it locked.

Yes you can - via a custom recovery you can flash whatever you want.
Pre 2.3.3 you could fastboot boot a custom recovery and flash whatever you wanted without even touching the stock recovery. That was never the intended functionality though and 2.3.3 took that ability away again (so that you now have to initially unlock in order to flash a custom recovery).
Thanks
Thank you Rem3Dy & krohnjw, I understand now. And thanks for the tip about flashing through rom manager krohnjw, its very usefull and easier instead of flashing manually.

erasing before flashing seems to help, I just use fastboot though as it's easy and doesn't have any issues. I don't recommend locking the bootloader if you plan on flashing, but it is possible.

I agree with you krohnjw as sometimes when you don't do a full wipe the new flashed rom gives you problems, specially with FC's, but I've never had a problem when flashing after doing a full wipe.
Hi I have just recently unrooted my phone and back to stock with stock boothloader and recovery.
I did this because I am just patiently
Waiting for the ICS update.
My questing is...how do I lock the OEM on my phone? I know you could but I want to know how. And ....if I do that....WOULD IT WIPE MY PHONE?
I want to relock my OEM, but keep all my apps on my phone.
So again, if I lock my OEM, would it wipe my phone?
PS. I have 19020A

Locking doesn't wipe anything. Unlocking wipes.

You don't have to lock bootloader to recieve OTA updates, unlocked bootloader just allows you to flash something via fastboot (usually CWM). Just be unrooted and have stock recovery, as I do. This way you can always flash CWM, make a nandroid backup and flash someting else...without losing any data (you don't unlock bootloader).
Ahhh damnit. Thanks krohn, had a bit of a brain freeze there.

Yea, why lock the bootloader? It doesn't need to be.
I thought locking the bootloader DID wipe. I guess I myself am mistaken too. (It would tell you though when you go to do it.).
Lastly, don't you think it's a little earlier to be going back to stock for the ICS update when it's not even announced as far as it being done and the phone; nor, is it announced of when the phone itself will be coming out. And, it won't be sometime till after that as well.
Just my opinion.
(You also didn't need to go unroot if you were stock rooted with no modifications).
Its just that I have lots of apps and I want to have them for when ICS comes out.
And....idk....I just figures if I am not rooted I might-as-well OEM lock just invade..if I might need to...for warenty

Nah your good on that... while it's rooted and awaiting the OTA... give your phone some Cyber air... over clock it with an app... install a better radio.. do something =]

Yes, you can be rooted, but you'll have to have stock recovery and you'll lose root with OTA update.

You don't need stock recovery. Stock recovery is not checked with an assert and is not patched, it is deleted and flashed using a full image. You can flash the OTA with CWM without any issues.
You will lose root in one of two scenarios with the OTAs, it recursively chmod's /system or formats /system (full update, not incremental). At this point all you need to do it flash the su binary again though to regain root access.

Does it have to be unlocked to flash a rom. I can easily unlock it. I know. I relocked it I'm anticipation of ics now am wanting to throw a rom back on. I just rerooted. Flashed cwm. Made a backup. Can I just flash oics or do I Have to unlock the bootloader first?
Hell, I'll unlock it again haha
But would still like to know the answer
U have to unlock it in order to install a custom recovery. But after that u might be able to re lock it and still keep cwm. Not sure tho

From what i've gathered, you'll need CWM or similar (not necessarily a locked bootloader AFAIK) to flash a non-stock ROM, the stock recovery won't do.
I had cwm after I rooted. Was able to make a backup. I just copied all contents to PC, unlocked boot loader, then just recopied and flashed the oics43. So far a little lag here and there but nice. Seems to be more functional than the roms were a month ago
i rooted my s3, then i unlocked the bootloader. i still havent flashed anything but now when i reboot my phone i get the custom notification with the unlocked padlock. did i do something wrong or is this normal.
edit: i used a windows based program to root and i used twrp to flash the unlocked bootloader
I am waiting on a stable completely functioning rom before flashing.

Sounds like it's not unlocked if you still have the custom boot screen. What method did you use to unlock?
You are not unlocked. When your bootloader is unlocked that Samsung screen just flies by. No padlock no waiting.

Thanks! i used a windows batch file to do the unlock...guess ill give it another go.
worked thanks!
My SGiii now does this when booting. I have root. I used the devFS root method. I to my knowledge I have not flashed the boot loader. Is this what people were talking about by adding one to there flash counter? If so I might as well flash cwm.
Is my warranty void now?

Has nothing to do with flash counter. It shows that software is modified and is caused by root. Unlocking the bootloader will get rid of lock. Warranty is void only if you don't revert to stock before return.
