 * 10 October -- Following the first limera1n beta release, geohot released multiple versions, each fixing bugs affecting previous releases. Chronic Dev Team officialy anounces that, in order to keep SHAtter undisclosed and possibly preserve it for 5th generation devices, greenpois0n would be delayed in order to incorporate this new exploit limera1n uses.
 * 9 October -- In order to push Chronic Dev Team to change the exploit used on greenpois0n, geohot rushed out a beta version of limera1n.
 * 8 October -- Geohot comes back to the scene with a new bootrom exploit believed to work on all devices, as shown on the resurrected limera1n web site. He prompts Chronic Dev Team to use his exploit instead of SHAtter, but, since greenpois0n is already scheduled to October 10, it may be not possible. Geohot ETA'd his limera1n release to October 11, if greenpois0n can't be changed to use this new exploit. This decision, however, would burn 2 bootrom exploits: SHAtter itself and the one used by limera1n, which is unpatchable by firmware updates.
 * 6 October -- Chronic Dev Team issues expected ETA of greenpois0n as October 10, featuring the new SHAtter exploit for devices with the S5L8930.
