I may have to return my ATRIX due to Let'sTalk horrible customer service, but I was wondering if there is anyway to re-lock the Bootloader, or to hide the fact that it says, Unlocked. Thank you in advanced

Also, I'm sorry if this is in the wrong section, as this is urgent to me and I have yet to see any otherpost relating this topic.

There is another topic like this.

No you can't re-lock and no you can't "hide" the unlock wording. Sorry.

Assume you installed 2.3 using CWM, if that is the case, you can flash the stock 1.8.3. Because the bootloader is not compatible with the unlocked phones, it won't show the "unlocked" text when you turn on the phone. I have tried it when I was trying to get rid if the unlocked text.

The down side is, you won't be able to flash custom ROM until you flash a compatible bootloader.

Reflash To Stock
Unfortunately, there is no way to relock a bootloader. Hence all of the warnings when you committed

but, if you use 4.5.91 the software at the address below should reinstall the newest stock software...

direct.motorola.com/hellomoto/motosupport/source/SoftwareUpdateSelect.asp?country=USA&language=ENS

be careful because Im not sure how motorola update will react to an unlocked bootloader. Ask around...do so at your own risk.

If you want to try a harder, albeit, safer method, and you are sure that you do not have a phone running 4.1.5.91, you can restore your phone to a factory SBF with this process:

briefmobile.com/motorola-atrix-4g-system-boot-file-sbf-leaked

DO NOT UNDER ANY CIRCUMSTANCES TRY TO RESTORE A 4.5.91 system to stock with RSD LITE.

To go to any of the blue webaddresses above, copy-paste them into your browser. Sorry, but I am not allowed to post links yet.

I wonder why nobody has created a CWM downgrade for US Atrixes. NFHimself made one for Bell or international users to go to 2.2.2 Bell and it works really well. Pretty much every partition is replaced. Great for masking that your boot loader is unlocked. Someone should probably do that for ATT to make downgrading less risky than flashing an sbf again...

The downgrading and hard brick problem stems from using the OTA update, so you won't hard brick if for example you upgraded with KP's 4.5.91.

You also should be able to flash the 4.5.91 SBF. You just can't downgrade. There are other threads about this.

The reason the fruitcakes were created and deemed safe by the devs were because it didn't touch the BL, which people believe to be the culprit behind the hard bricks. NFhimself was brave enough to testing flashing the BL via cwm in his gobstopper on international phones, but I don't think any other devs are willing to risk hard bricking their phones by testing that theory on US phones.

There also isn't enough "reward" for doing so because if people want to downgrade they can use a fruitcake. The only gain is to get rid of the "unlock" text. But if you were really that concerned about it despite reading all the warnings of this will void you warranty, you shouldn't have unlocked in the first place.

Hi,

One of the reasons I did up a default CWM of 2.2.2 is to have a means of doing a reset after trying all ATT/ORANGE/TELSTRA/MOVIESTAR/etc firmwares out there which may have side effects or accumulated side effects. Hence the inclusion of the stock bootloader and radio and a write of the extra partitions to clean up whatever mix and match leftovers are in there from the various carriers. The other big one is just to be able to get a Bell OTA applied when it comes out, it will probably be similar to the leak, but best to be safe.

This is more of a Bell/Intl issue as ATT folks tend to run just ATT firmware or flash just boot and system via CWM/fastboot and don't have the same issues as flashing a sbf file.

Both the stock 2.2.2 and leaked ap20 OTA bootloaders from Bell are safe to flash after IHOP, this is not the case with ATT bootloaders and may be the case for any included in a sbf file. Finding out the hard way is not an option.

Cheers!

Say I unlocked it at 1.8.3 should I go down to 1.5.7? Is that safe?
