Danger, Will Robinson!! Lol.
EDIT:
* "Sarcasm" was fully intended here.

The CM update guide doesn't say to change your bootloader, all you do is put the disable lagfix file, flash overstock and then flash CM7.
What's the perk and what is supposed to happen if you don't have a GB bootloader and run a GB rom?

Yeah. Aside from a more convenient 2-button recovery access (and flashing one of adyscorpius' custom bl's), it doesn't seem to be the major issue (rainbows mainly) that it once was.
Although I did run into issues not being able to get into recovery running Froyo BL's on an older ICZen rom. That issue had since been addressed by mr_psycho (in the kernel), so life goes on.

[Q] where can I find the froyo bootloader?

I did read the instructions for upgrading stock to cm7.
It said that I need froyo bootloader
I can't find it, so maybe someone can link me to it.

I believe, that they are referring to something along the lines of Clockwork mod, cuz I just flashed coming from Trigger Final to CM7 last night, using CWM and it went flawlessly =)
I think I know what you're referring to. Flash back to stock (jfd) and them use lies mini to upgrade to kb5. This gets you gve bootloader tbeurw talking about. Then flash back to jfd and flash whatever rom you want.

GingerBlur has nothing wrong with it, but you would imo be better to unlock your bootloader and head on over to GB like most of us and get some of the goodness from the work the devs are doing for it.

All you got to do is do a nandroid backup and restore if it messes up B)

Stock

Me and my brother both have atrix's. I want to go back to stock because I heard its the best for my webtop, he has the original stock file. If i am on wetdream, and I go back to stock, is there a chance of bricking it?
Thanks.
You are best to use the fruitcake of the stock version you want and flash from recovery like you did with your current rom..there is a thread of all stock rooms here in dev forum. I'll find and link in a min. These are as safe as it gets.
Here is the link http://forum.xda-developers.com/showthread.php?t=1163009
Wetdream can run webtop as it is a stock based rom.

Yeah, grab the webtop from here > Fruitcake thread.
Thanks, I have it, but its way too buggy =\
If I flash it with my brothers stock, could I OTA update? He said he has before.
If its stock froyo based "stock file" assuming you mean an SBF, then you run the risk of hard bricking. If its a fruitcake. "Stock file" then you are fine. Never flash froyo SBFs anymore. They can be dangerous.

[Q] Downgrade from 4.5.141 to 4.5.91

Is it possible without hard bricking the phone? The upgrade is causing WAY more trouble than it's worth and a lot happier running roms. Thanks.

Got another question but not gonna make a new post, can you use the auto boot unlocker to unlock/root 4.5.141? It's only updated to .91

I can at least keep this alive and going. Mine was previously unlocked, and, once the update applied, which did it overnight without my permission (HNNNGH), I lost it. What do I do now?

Yes /10 char
I think you will find that you just lost the unlock graphic; unlocking involves burning out one of the eFuses, so you can't relock.
Hi everone
Im using a rooted, BT UL Atrix 4G with 2.3.6 4.5.191. and Im wondering if this is possible to perform this downgrade or/to 2.3.4
I want to do that becouse my GPS takes a lot to get a fix and I had no luck with other methods like: changing gpsconfig, recalibrating compass, using different radios
Thanks
Downgrading to 2.3.4 IS POSSIBLE provided you have previously unlocked your bootloader AND you have a backup of 2.3.4 through CWM.
This is treacherous territory, and I'm not sure if there's been resolution on whether or not it's safe.
Your safest bet? Fruit cake it back to 4.5.91.

No that would brick it and you would be screwed. We already saw this issue when people tried to go backwards from GB to Froyo...

I have used the automatic bootloader unlock for 4.5.141 but I may be just lucky

Yeah it is working fine on 4.5.141 ... Unlocked and Rooted, running Neutrino 2.8 GT
But the phone is heating up even @ 1 GHz. (no undervolt)
So was curious if flashing the ROM over 4.5.91 will help or not.
- Is it not possible to downgrade even using Nottach's method? Flashing the 4.5.91 images directly from fastboot and not bothering with RSD ?
NVM...

So is it feasible?
Downgraded successfully by flashing the separate partition using moto-fastboot.

2.3.5 custom recovery flashing?

Is it possible to flash a custom recovery with the locked bootloader? I'm used to HTC and am not to familiar with Motorola's Android

I have already successfully rooted, and attempted to flash CWM recovery from Rom Manager, but I am unable to get to recovery. I tried to unlock the bootloader with RDS Lite flashing derpunlock from the puddin forum, not the 2.3.5, but it failed

Need to use the boot strap recovery, MOTODX_Bootstrap_Signed.apk. Its based off Clockwork. Make sure you only try to flash locked roms though. If you try and flash anything not supported your more than likely going to be on my boat... Softbricked. I was a flashaholic with my Evo, now im a bricked bum looking for light...
Look in Lokifish Mars Sticky on all thing Mopho. It has links to everything you will need in it.
No you cannot flash a custom recovery on a locked bootloader.

I'm in the same boat. I just got a used Photon and it already had the 2.3.5 (45.4.13 254_13) ROM on it. I got it rooted successfully at least, but get the error when trying to install the DERPUNLOCK.SFB file.
Any solutions out there yet? Can the unit be SBF-ed back to 198_7 and then the bootloader unlocked?
(I'm sorry if this is a redundant question, but I haven't found a clear answer and have searched the forums extensively!)
THANKS!

Your only real option is mof2.3.5 unless you want to run a rom that is not supported anymore ie imperium, rocko, skinny. Mofs rom is damn good though. Give it a shot and see what you think.
If your on 2.3.4 go with mofo2.3.5ish if your on 2.3.5, don't flash any roms locked or unlocked. Just be happy your phone works!
The reason being is because will the roms are based on 2.3.4 and since 2.3.5 locked bootloader, anything 2.3.4 based will cause you to soft brick, with no sprint sbf to fall back on. Peetr and mo are actively working on a working sbf for those who are on USC electrify sbf.

Signed boot.img with its modules is needed to install after each locked rom.
Don't want to sound like a n00b, but where would those be in the ROM threads? I'm so used to HTC's phones, so going to this Photon makes me feel like I'm starting from scratch...

Actually nowhere yet. You need to wait.
Ohh okay. I'll just sit back and wait for the devs. Really wish I hadn't traded my Evo LTE for this Photon....
