[ROM][NS4G][GRJ90] full_crespo4g-eng 2.3.5 built from source. *UPDATE 8/14/2011*
I decided to go a different direction from the "bleeding edge" of Android and built a fully working, very stable GRJ90-eng build.
Native tethering working and stable (3G only)
A few data tweaks over the Sprint GRJ90 tweaks for better data throughput and stability
1x and 3G icons displaying correctly (Sprint decided to drop the 1x icon while on 1xRTT)
4G Tethering... not much I can do with this right now until I get word about custom drivers.
VPN connections won't connect/authenticate
Auto-Rotate sensor - module wasn't included into build for whatever reason.
It's come to my attention that people think there is a bug with the stock recovery reflashing itself on reboot. That was my intention; I wanted it that way for security reasons. If you don't know how to use fastboot, or download/flash from the phone, an eng build is probably not for you.
I have included an update.zip this time, so you don't have to fastboot the ROM
08-14-2011 UPDATE [Fastboot only]
Let me know how this one works for you. The recovery reinstalling after every boot should be fixed with installing via fastboot.
8/3/2011 OTA.zip build
Download NS4G gapps
I am also including the stock bootanimation.zip if you'd like to use that instead of the stock Android kernel one.
Instructions to install:
Do a NANDROID (need it if you want to fastboot your data img back on if you are using a GRJ90 based ROM)
Wipe ALL partitions and cache
DO NOT REBOOT - Flash gapps, REBOOT
with MHS enabled
CDMA Only selection and 1x status icon
Hybrid Mode selection and 3G status icon
