I just wanted to say THANK YOU for this sargentmajord, I managed to brick my phone today after successfully upgrading to .902 yesterday. I was attempting to install the latest ICS4BIONIC Alpha, and I booted into it fine immediately after flashing, but I had to bootstrap back into recovery to install the GApps.zip, and after I completed that, the phone wouldn't boot past the Motorola logo. I'm not sure exactly what went wrong and where, but every FXZ I tried to flash in RSD Lite failed at some point or another (I tried a variety of .893 and .886 FXZs), except for yours (at the bottom of your OP). I just got done getting back to stock .902 and can now restore my nandroid of .902 that I made last night. This time I will definitely be trying the ICS4BIONIC Alpha in Safestrap, don't know why I didn't the first time like I did with all the other alphas up to this point (probably over excited about it having 3G/LTE this time). Anyways, thanks again this post has officially eliminated my headache lol.
P.S.
For those going from .886 to .893, if you flash the .893 .zip in stock recovery don't forget to have replaced the CDT like the OP says to. If you do forget (like me), here's a quick workaround that won't require you to start everything over:
If you just installed the .893 in stock recovery, and upon rebooting your phone gives you the black and white screen saying something like "flash failure" and/or "CDT Failure", download this file:
FixCDT.zip
Then:
1. Extract the zip file you just downloaded (somewhere visible and easily accessible to you)
2. Plug your phone into your PC using your USB cable (with the black and white screen of error messages still showing)
3. Run the "FixCDT.bat" file you just extracted from the zip file in Step 1 - I think it asks you to hit enter or something once and only takes a couple of seconds to complete.
4. When it is done, power down your phone and power it back on. You should be good to go :biggrin:
I take no credit for the creation of this helpful .zip file, I downloaded it earlier today and honestly can't remember what post I grabbed it from. Thank you to the creator, I will update this post when I figure out who you are lol.
