Root [MetroPCS/CDMA] Flashing question

[starstress]

Ive had to restore my backup 5 times since I got this phone 3 weeks ago and why you ask? Ok so whether its a rom, mod or kernel the insturctions say to wipe cache/dalvik cache as they have sine the beginning of time it seems but whenever I do that once I reboot I get stuck at samsung galaxy s3 screen everytime but when I dont I get a normal reboot. "so just dont wipe the cache dum dum" you say? Ok well I wanna make sure I wont have any ill-gotten effects in doing so. Any one else experience this?

depending on the rom it may have some dalvik tweaks etc.. so when you wipe dalvik cache it has to rebuild on the first boot of a new rom installation.. so it usually takes a while to boot, but it should only hang at metro screen not samsung.. if it's hanging at the samsung screen then i think you may need to do a data wipe.. are you coming from pure stock? because that is ODEX and 90% of the roms are DeOdex'd

happy flashing

I was coming from metropolis. Now with the kernel I realized it's because I'm on 4.2 and the kernel didn't support it. Dirty flashing mms fix and a sound mod I wanted flashed fine. But your post definitely educated me
