SpecterDev has just released an update to his implementation of the umtx exploit chain, porting it to Firmwares 3.xx up to 5.50 included. This means the exploit chain is now working on all Firmwares up to 5.50.
5.00+ the ELF loader currently doesn't work, because we can no longer properly invoke dlsym, payload SDK needs changes.
