CM7 dosen't change any settings. just install bootstrap recovery on whatever stock version of the alltel ROM you have and away you go. IF you try installing one of the nighties instead of the first beta than you need to change some code in the nighties and re-zip the package this is how you do that:
The Install of CM4DX runs a check_kernel script that looks for the Verizon version of the Kernel, but the alltel one is different
The check_kernel script looks for:
This is Verizon's Kernel
"Linux localhost 2.6.32.9-g55626e1 #1 PREEMPT Sun Nov 7 23:24:32 CST 2010 armv7l GNU/Linux"
This is Alltel's Kernel
"Linux localhost 2.6.32.9-gace4441 #2 PREEMPT Mon Feb 7 18:23:06 CST 2011 armv7l GNU/Linux"
so to make the install not even look for the check_kernel we have to change some code, don't worry doesn't do anything except make the install not check for the kernel version.
extract any of the nightly zips and go to here
META-INF\com\google\android
Look for the file updater-script
right click on it and click open with... notepad or if on mac right click open with... text edit
remove these three lines from the code, it should be at the very top of the code
package_extract_file("system/etc/releaseutils/check_kernel", "/tmp/check_kernel");
set_perm(0, 0, 0777, "/tmp/check_kernel");
assert(run_program("/tmp/check_kernel") == 0);
save the updater-script
repackage the zip
install in clockwork, and after it successfully installs let it reboot, it will do a boot loop, go into stock recovery clear data and cache and reboot
You now have CM4DX on A Milestone X
