[Q] Q/A Official ATT Gingerbread OTA UL BL Root

Thx for your support help and patience to me, kind of new in this stuff, here is my question and I hope someone with absolutly real experience can answer.
Here is my reality, I have an Atrix with the new OTA update gingerbread, no UL BL, no root, no mod, clean...Can I still unlock the bootloader with the2dcourt guide in briefMobile? or I am stuck in the world of no mod forever? This is because I am tired of searching. someone guy s say you can, other say can´t (BriefMobile for example)...I really apreciate the help and a little guide just the names of treats or files I would search
I'm in the same boat, was waiting for the official update before making any mods, and I have to say, after a couple of hours on here this morning I'm a bit confused.
I got root fine (brief mobile's is solid for that) but now I'm trying to figure out the BL. Some posts say the OTA will hard brick if an SBF is flashed, others point to guides that use the SBF flash...
You can still unlock the BL with pudding and install CWM to flash custom rome. Use the preinstall method to root or use a pre-rooted custom rom.
DO NOT try to flash back to a stock froyo build or you will hard brick.

You will only hard brick with the OTA if you attempt to flash back to 4.1.83 or earlier stock builds. You can use the fruity cake builds (as they have pudding in them) to go back if you had to.
From here on out you have to use pudding to unlock the boot loader to enable custom rom flashing. Just follow the pudding thread for more info on that.
You can't flash an older SBF file, that will cause you to brick. The SBF files you should avoid are pretty much all of them except Gingerbread, Unlock, and Radio SBF's.
You can unlock your device even though you've updated. But you're stuck with that bootloader forever, but you can always downgrade with a fruit cake I believe.
It all seems confusing at first, but you'll get the hang of it!

Thanks for the vote of confidence! I had run several custom roms on my G1, but much less of that experience is proving to be helpful than I had hoped.
Thanks everyone for your speedy replies, I'll go give pudding a shot after breakfast.
if i flash pudding, just the unlock part and then fastboot the unlock....will i have to load a rom, or will gingerbread 2.34 still be there?
Okay, so the official pudding thread recommends beginners follow Brief Mobile's BL unlocking guide. I did, and got the message "oem unlock is not implemented". However, the 1st step in the guide is "If you’re on Gingerbread, skip to step 13". I am on GB from the OTA, but the guide was published a month ago, before the OTA update.
I'm guessing they said that because at the time it was published, you would need to have already done those steps to be on GB, so I may need to go back and follow through all the steps I skipped the first time. But if they had GB users skip steps because they would be harmful to GB phones, then that would be bad... Advice?

Go through the whole thing. If you soft brick, just run fastboot oem unlock again.

Step by step ULBL, Root for OTA GB
**I've been getting PMs for clarification: I didn't do a single mod to my phone before this morning. Stock ATT/Moto Atrix, installed stock ATT/Moto OTA GB update yesterday. Following these steps I am now BLUL and rooted.**
So here are all the steps needed to get a stock, OTA Gingerbread Atrix Unlocked and rooted:
1. Follow Brief Mobile's BL unlock guide here.
Things I found out that you may like to know:
-You will need to complete all steps *even the ones the guide says to skip*.
-When you enter your device unlock code, it is case sensitive; use caps-lock.
-The most recent SBF flash is in the XDA IHOP pudding thread, use this instead of the older file linked to in the Brief Mobile guide.
-When you are done, reboot will take a *long* time; just stay calm.
Edit: After 30 min on the dual core screen with the "unlocked" in the corner I pulled the battery... after reboot everything seems fine.
2. Follow Brief Mobile's guide to root here.
Thanks to brief mobile, and to the xda folks who held my hand through this whole thing the first time

If you don't know what how to lock it on Nord 2, it is better not to write disinformation here.
<Moderator Edit>: Removed quoted post due to being deleted at poster's request.
No you right if you use your device, but he wrote in OnePlus Nord 2 theme, that's why I told you that you way to lock bootloader isn't applicable to rooted Nord 2 device.

Question How to move from miui 13 ID to miui 14 Xiaomi.EU rom

I'm completely new to all of this and afraid of missteps, I've been reading some tutorials and still can't understand it, all I know is the file I'm using is recovery and not fastboot
Can someone teach me please as I am really afraid of getting bricked
You should follow the steps under
"Installing with TWRP: (ROM Type: Recovery)"
from the MIUI.eu page
Honestly, it's not easy to explain it any better than that post, there's also a guide on how to install TWRP
Note: you must have the bootloader unlocked. If it's still locked, you will lose all your data unlocking it
