[Q] Help! Soft Brick/Possible Hard Brick - Atrix 4G Q&A, Help & Troubleshooting

First off, I'll be brief, but I'm new on the site. I've been around looking at the forums here and there which helped me to previously root my Atrix.
I had intended to return this phone, but it's watermarked which sucks. Whatever, there's nothing I can do about it now. For fear of it not being returnable I decided to wipe the Atrix and unroot the phone. I first ran aRoot to unroot the phone. Everything worked to basic perfection unrooted. I deodexed back to 1.83 to get rid of GingerBlur, which it did. I did notice, however, that the phone would still boot into Tengar's CWM Recovery Mode when plugged into a wall charger while powered off. In a fit of absolute stupidity, I formatted everything that it is possible to format while in the CWM Recovery outside of my microSD card. Now when I reboot the phone it sticks on the "Dual-Core Technology" with Moto logo screen. No boot whatsoever.
After freaking out for a good hour or two I tried a couple of things I saw on this website because I can get into the general phone recovery (by holding down the volume button). All of them have been no-gos for me so far.
The recovery from a soft brick on the wiki gives me "Cold-booting Linux/ Reading ODM fuse: 1" when using Early USB Enumeration and sits on that indefinitely which takes out ADB. I can boot into Android Recovery mode, but, as has been noted on that topic, you can't load any update.zip files as the microSD card is not mounted. I also tried doing a wipe data/factory reset via Android Recovery but that's a no-go as well. On the bottom left it does say "E:Can't open /cache/recovery/command" in AR. I thought about flashing back to 1.83 or older using RSD-lite, but I get "Battery is too low to flash" every time when going into RSD mode.
Outside of these problems, my phone will turn on when plugged into a computer, but only to the same screen mentioned earlier and it takes nearly and hour after the charge has been (presumably) completed. The phone will not charge via USB wall charger - instead the phone turns on. I have no flashing red LED or any other warning messages nor can I turn the phone on without it being plugged into a USB cable.
When AR is run for factory reset:
.Performing BP clear...
.E: open mdm_ctrl ok
.E: bp status before bp power down 0
.E: (0,success -1, failed, 1, panick), return result: 0 after BP shutdown....
E: begin BP power up.....
E: reture value of bp start up:-1
E: bp status after bp power up 4
....E: from flash to normal mode
....E: open dev
E: engine init finished
E: Successfully wrote 13 bytes.
E: Transferred 13 byte(s) CMD opcode = 0x0012 to aux engine succeeded.
E: write finished
E: Attempted to read 12 bytes and read 12 bytes.
E: Successfully read 12 bytes.
BP clear complete successfully.
Formatting DATA:...
Formatting CACHE:...
Data wipe complete.
After which I let it reboot. It sits there at the logo, still, no matter how long I leave it plugged in.
As a side note, last I remember, my phone was set with USB debugging on and to be a Mass Storage Device.
Please, I'm desperate right now. This is going to be my only phone for the next two years, whether I like it or not, and I'd like to keep it (besides, I do quite like it).

i did not understand quite well your situation but in a desperate time this is what i would do:
to bypass the low battery, you need a usb cable:
open like the picture
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
insert the red one between battery and its connector on the phone (the + on the battery will tell you the correct "slot" ) battery needs to be correctly inserted.
plug to the pc
the phone will think it's fully charged.
then plug a normal usb cable to pc and phone enter rds mode and let the process begin, full sbf (not service) advised
let it go

Well, as helpful as that was, the cut-a-USB-to-charge trick didn't quite work for me. Might anyone else be able to help me? My phone is as dead as a door nail atm.

same here...
Me too, have a very similar problem, but not because of flashing ( I think so ) ..
Chronology : have use phone regularly with Froyo, rooted, no unlocked bootloader yet, no micro SD card ever inserted, can access internet with small download speed.
The problem arise (as per I remember correctly),
first, I install Calc-P (sideload from androiddev dot orkitra dot com) , install then use it, no problem ..
second, update Android Assistant from market, install and use, no problem
third, download then install Smart Taskbar (com.smart.taskbar)
download went fine, but during install, it takes like forever to finish, AND it doesn't!
unfortunately, my battery on that time was dried off, and the-install-takes-forever just died.
after a full recharge, I turn on, and used the phone ok for a while, until I realize there are some app (from market) that I don't regularly use, so I decided to uninstall it.It also, TAKES FOREVER with nice black&white rollover progress bar.
I think, something went wrong, so, panickedly, I turn off the Atrix.
And now, just stuck on Rethink Possible bootscreen, no where else.
-tried android recovery : no go
-tried android boot (no bp) : no go
-tried fastboot : no go
Someone, please, how to solve this.
Problem solved by wiping all data and apply pie crust (from navalynt) onto those already crispied gingerbread ..
