Here is a guide on how to complete the Diamond Store heist without setting off any alarms. I have included a video demonstrating how the execute the plan but remember that each game has a variety of randomised elements which means you have to adapt the plan to your particular spawn.
Mission Objective
Loot the specified number of bags of jewellery from the Diamond store.
The Plan
The cases are all alarmed so before we breach the building and start taking hostages we need to disable the alarm and take out the cameras. Normally there is a side door to the security office on the left side of the building. Pick the lock and dominate or kill the guard inside. Check in this room for the keypad to disable the alarms - if it's not here it's probably going to be on the second floor.
The keypad looks like this:
Once the security room is under control, go around the back of the building and up the stairs to the rear entrance. Break into the back of the building, locate the keypad if you're missing it and locate the bank manager - she will routinely wander around upstairs and down on the shop floor, so wait for her upstairs.
With the keycard, disable the alarms and then prepare to storm the shop floor. Just before entering the shop floor, set up an ECM to block calls to the police and buy yourselves a little time to get the situation under control. Feel free to keep deploying ECMs for as long as it takes to get the civilians under control.
You will need one of your crew to head outside and control and tie civilians in the street and the owner of the shop next door. Remember that there is a courtyard out around the back of the diamond store and that civilians will sometimes wander around from there either via the side of the auto shop next door or the alley with the security room on it. Once outside is under control, this crew member can be used to move bags to the van - but always keep on the lookout for more civilians.
The remaining crew members inside should take care of all of the cases and drilling of safes if required. Bags should be thrown out onto the street to ensure the crew member outside can load them up in the van. Once you're done, get out of there.
Abilities I would recommend for this map are:
- somebody who can Dominate the guard in the security room,
- at least one crew member who can place ECM to block calls to the police,
- everybody with skills to increase movement speed with bags (Transport), interaction speed with bags (Fast Hands), etc
This map has been seen to spawn with very few guards, but in the event there are any guards that need to be dealt with, the usual skills apply for controlling the situation:
- at least one crew member with the Smoother Talker ability,
- at least one crew member with the Cleaner ability aced to dispose of bodies
Here is a video of the Diamond Store heist being completed without setting off any alarms:
I've seen and heard a lot about this ambush.
From my experience, finishing the day one without triggering the alarm will insure you to avoid it. The wiki seems to confirm it:
Note: If you have successfully completed Day 1 in stealth, you will not be ambushed on Day 2.
It also says that
If you have not successfully completed Day 1 in stealth, there is a chance you will be ambushed though it is random, it is possible to go loud on Day 1 and have no ambush on Day 2 if you escape during the hostage phase.
I've also seen a guy putting an ECM jammer on the cell phone instead of answering it, before the second phone call. He wasn't sure, but thought it would reduce the chances of an ambush.

Here is a guide on how to complete the Framing Frame heist stealthily. I have included videos of each day demonstrating how the execute the plans but remember that each game has a variety of randomised elements which means you have to adapt the plan to your particular spawn.
Day One
Mission Objective
The Elephant wants you to frame a senator, you're going to do this by stealing paintings that have just been sold from an art gallery, framing them in frames with cameras fitted into them and selling them to the senator. The art gallery has up to nine paintings marked with red sold stickers stickers, get them.
You need to steal at least four paintings. Get the paintings from inside the art gallery to a van outside.
The Plan
The art gallery has a total of six guards, one of these guards will remain stationed at the front desk unless alerted, and another will remain in the camera room until you breach it.
You will need the following abilities between your crew:
It's best to also get the Camera Feeds asset, and position one of your crew (that isn't responsible for any of the above abilities) on the camera feeds to help mark the guards. Assign another of your crew to scout around on the roof, helping the two breaching the art gallery by marking cameras and guards.
One crew member can breach via the roof if you want but my favourite method of cleaning up the guards is to draw them towards the bathroom at the front of the art gallery (there is a pickable door outside on the way up to the roof) by activating the hand dryers. This allows you to pick off the first four guards one at a time without drawing too much attention to yourself. Bag these up and hide them in one of the cubicles.
Spot the camera in the first hall from the roof before running in, and start clearing up paintings. Throw the paintings up to the spotter on the roof and he can throw them over towards the van.
Move from room to room, spotting the cameras from the roof first until you reach the room that is blocked off by lasers and then exit the building.
Normally by this point you have enough paintings to fulfil the objective but if you want or need more you can have one of your crew members breach the last room from the roof while the two of your crew move the paintings to the van. The spotter on the roof remains in position to catch paintings.
To exit, kill the guard and quickly run over to the van before the pager times out (the Sprinter ability is good for this) and you'll get out without an escape.
If all goes well, you'll be in and out without triggering an alarm and you'll get an achievement - Painting Yourself Into a Corner.

Day Two
Mission Objective
Get the paintings to the buyer, get the cash to the van.
The Plan
The plan is simple - get the paintings out of the back of your van, into a train car nearby that has a ringing phone in it. Answer the phone to start the deal with the buyer and he will request that you all get into the train car and throw the paintings out through the roof.
For each painting delivered, you will get a bag of cash. Don't throw the last painting out until you've got all of the bags of cash over to the door at the far end of the train car as doing so will start the next section of the mission. Get the cash out of the train car and head towards the getaway van - ensuring that any civilians who see you are controlled quickly, or several ECM jammers are used to stop anybody phoning the police.
If you happen to get all nine paintings on day one, you'll get an achievement once you've completed trading the bags - Big Deal.

Day Three
Mission Objective
The objective of day three is to break into the senator's house, steal five of his personal gadgets that can be used to gain access to his desktop computer, use the computer to gain access to the vault, plant cocaine in the vault and (optionally) steal all of the gold.
The paintings you stole on day one have been fitted with cameras, which can be viewed using a laptop on the roof. During the first stage of the heist you will want one of your crew members watching these cameras constantly, marking guards and locating the senator's gadgets.
The Plan
You're going to break into the senator's house, take out the first four guards and answer their pagers - dispose of the bags on the roof near the start so that nobody will find them. The fifth guard will need shouting down. You can mix this up a bit - if you get an opportunity to shout down a guard in a part of the house that nobody else is going to go, or within a timeframe where the other guards will not be a problem, then do so.
You will need the following abilities between your crew:
There isn't a security room in the house so you can't directly take control of the house cameras. You can, however, melee them to break them and clear yourself a path to the vault.
Find the five gadgets and take them to the laptop on the roof, which will allow Bain to unlock the desktop computer in the office upstairs. At this point you'll need to assign a crew member to use the computer, as it is used to open the vault and also temporarily disable the lasers in the vault.
Once the vault is open, you'll need to turn off the lasers with the desktop computer - these will only stay off for around 15 seconds but they will beep several times before reactivating.
Once you've got the gold out to the vault it should be a simple case of transporting it all to the exit point on the roof. If all goes well, you'll be in and out without triggering an alarm and you'll get an achievement - I Wasn't Even There!
