Ok, I struggled with this for a while in much the same way as everyone else, then i realized it wasn't a bug at all, but that I was an idiot. All you have to do is hold down the conceal button, which pops up a menu that you scroll down to select the bomb, and then just drop it, and select the remote the same way... I feel like a jackass, and maybe there really is a bug there, but I finally figured it out for myself.

I dont think theres a bug, I figured out first try.

Actually - reading another post, think I heard the solution. Haven't tried this yet to make sure, but seems logical. I tried to arm the bomb much earlier in the mission to blow somehting else up. So it must have still been armed when I got to the sewer. Think I just have to back and do it over.

Hey I tried that and it didn't work I pressed the council button the one that make little menu appear in the right top corner I held it and pressed drop button it didn't work any other ideas or did I do something wrong???
Please tell because I can't go anywhere els I killed every body rescued the guy, soldier whatever. Nothing please help...

I armed it first and then dropped it. Ouch.

I used the cheat to get the minibomb. Armed it, dropped it near the wall...moved away and used the remote. It blew up, but did nothing to the wall

I have tried all the ways to blow the wall up and it still is not working do i have to hold down change or what

Step 1: Get mini bomb and remote control
Step 2: Get to the almost broken brick wall with the exit towards the sewer
Step 3: DROP the bomb to the ground when a message tells you to do so.
Step 4: Step back untill a message says that you´re at an ok distance
Step 5: Equip de control remote, and activate it with the trigger button.

That´s it, then you´re on your own.

Hi, i'm really stuck in level 4. I can't get the mini bomb to work. The weird thing is that i can't arm the bomb unless i use the remote first. Then when i drop it, it explodes in my hand. If i don't arm the bomb at all and drop it, it explodes aswell. Can anyone help me with this??

to get the bomb, hit "i" for inventory and then hit your left directional button and that wil let you scroll down on the upper left screen.
