HTC myTouch 3G Slide Status Report
This device is the HTC myTouch 3G Slide (espresso). This is going to be very similar to issue pmbootstrap#1203 (closed), except for the fact this device uses an ARMv6 MSM7227, which does have a FPU (VFP). Here's proof:

I've successfully gotten 2 different(?) kernels to compile (LineageOS/CyanogenMod and a Linux 3.0 port someone was working on). Both use the timeconst_fix.patch.

pmbootstrap flasher boot yields only the stock boot image (not the HTC logo in the RUU mode), for both kernels, and using the pre-built kernels from the stock rom and the CWM 2.5.0.7 recovery. The device is seen under lsusb, but doesn't show under ip a. Flashing the kernel/system image also produce (remote: image update error) except for once when it actually worked (I believe it was the 2.6.29 kernel), but gave an error due to being unsigned (as I have S-ON - not possible to get 'S-OFF' since I updated to unlock the bootloader).
Installing via zip/recovery also doesn't work (see #161), but even when bypassing this the screen goes black for a second and the recovery restarts. This may be due to the recovery being too old, I'm not sure.
I also created a wiki page here.
