So like pretty much everyone here I have had completly random shutdowns from the lock screen on v2.1. Ive tried different kernels and changed my min clock speed and usually i get about 4-6 shutdowns a day. Today I downloaded petesscripts.zip and put the free50mb script in the xbin folder. started up my terminal ran the script changing it to have 50mb of ram free. Ive been at work for 9 hours now using my phone all day and not 1 single shutdown yet. Can others try this out and tell me if you works for you?
