Hello, I wanted to revert my ROM to stock in order for me to get the TMO update. I was wondering if I could get it on a stock ROM backup I have (no root) or will I need to relock the bootloader and have no custom recovery? Thanks.

One more question, I forgot this part: will locking the bootloader wipe everything (sdcard)? And will unlocking it wipe everything (sdcard)? Thanks!!

It will only erase data and apps....anything on your sd card will be untouched

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.

I discovered a scratch on my screen and need to get this replaced. Right now I'm on Verizon running Android open Kang project jb with an unlocked bootloader.
I want to return my phone to barebones stock do i just flash the stock zip in odin and the bootloader and I would be good to go?
Also if I get this replacement in there different baseband version does this not allow me to Install aokp or other roms

Yes, just Odin stock G1 or F2 image, the do a factory reset, clear all data cache, you should be fine. Your replacement should be a G1 version and you can install any rom over it.

Thanks. Side question if it was other version would it not be able to install ROMs?

Dont forget to re-lock the bootloader. Odin doesn't do it for you. Read the sticky about "how to return your phone back to verizon" in this very forum
Nope, you can install custom rom to any version.

We did, but I actually went thru the process and it doesn't lock the bootloader using Odin.
And if for any reason your bootloader STILL isn't re-locked, you can simply use EZ-Unlock (the app) to do so.

Refer to our discussion in this thread.
If I'm on a rooted unlocked bootloader device and I did a factory restore :
1. Will I lose the root ?
2. Will bootloader be locked ?
3. Will I get the stock ROM ?
4. Will I get the latest software update ?
Sorry for too many questions and thanks in advance

It depends on how the phone manufacturer implements the factory restore. Each manufacturer implements different strategies.
In a worst case scenario, you lose everything and get back stock ROM with nothing else.
Motherhood advisory: Backup everything and be sure of the processes involved before you do the factory restore.
Depends. If you factory restore through recovery, you'll be at a fresh version of whatever Rom you have.
If you do a factory reset via the computer, or flash back to stock in Odin, you will likely have to root and unlock the bootloader again.

I have had my moto g for a while now and I am quite tempted to root it. But then having an unlocked bootloader would not allow me to receive any Ota updates if I am not wrong. Is there any way to receive updates with an unlocked bootloader because once I unlock my bootloader, I am not going to relock it again..

You will get OTA updates in rooted phone and you can Install it if you have stock recovery... You can't install OTA update If you have custom recovery like cwm or twrp...

So that means before updating I need to revert back to the stock recovery before updating.Also can I download the entire Asian stock firmware and then flash only the recovery using adb?Thanks for your help.

Flashing recvery wont work, you need t go back to full stock rom , update it, and do flash custom recoery and root it.. I tried long back flashing stock recovery and update, but that didnt work for me...
