The HP Veer

First, here is the rear of the device before disassembly starts. As you can see, it's an AT&T Veer.

To be very clear, this is a device which was purchased at full price off-contract from an AT&T store. There are no strings attached to this device. It was not a free or discounted developer device. The device did not come from HP. There is no NDA, embargo, convenant, or other restriction on this device.

It was used to test Preware, Impostah, Govnah, and other homebrew applications for the Veer. All that was very successful, and I can report that all tested homebrew applications and patches ran safely and correctly on the Veer.

Then it was used for further hard-core command-line investigation into the new "tap to share" interface (which is controlled by an "A6" chip). That's when things went wrong, and the device was permanently bricked. To prevent this happening to you, stay away from the PmA6Updater binary.

Hence there are no qualms in dismantling it. So that we shall do now ...

Initial keyboard separation

Separate the plastic around the bottom of the keyboard and the sides of the phone using your fingernail or a spudger.

Veer 03.jpg

Veer 04.jpg

Initial lower half separation

Further separate the backplate at the bottom of the phone and along the sides, but do not pull it any further apart than this.

Veer 05.jpg

Note that the volume rocker switch is part of the backplate ...

Veer 06.jpg

... but the magnetic connector is not.

Veer 07.jpg

Initial upper half separation

Now separate the plastic around the top of the phone, but do not pull it any further apart than this.

All the switches along the top of the device are part of the backplate.

Veer 08.jpg

Backplate separation achieved

The backplate is now fully separated, but do not take it further than this at this stage.

In this shot you can see the lanyard attachment opening at the top left corner of the phone.

Here is the left-hand side of the phone.

Here is the bottom of the phone.

Here is the right-hand side of the phone.

Warranty sticker

Note the white warranty sticker between the backplate and the body of the phone. If this sticker separates from either the body or the backplate, your warranty is voided.

The tiny white rocker switch near the camera is the mute switch. The plastic slider which actuates this is part of the backplate.

Here you can see the flex cable which connects the circuitry in the backplate (touchstone coil, touch to share, volume rocker, power switch) to the main body of the phone, somewhere underneath the battery.

Battery removal

It is possible to remove the battery without dislodging the white warranty sticker.

Battery cage removal

Detach the magnetic connector flex cable, and then unhook the battery cage latch.

Veer 20.jpg

Here is the connector you need to detach before attempting to remove the battery cage.

Veer 21.jpg

Battery cage removed

Detaching the metal latch on each side allows the battery cage to be removed, exposing the location of the flex cable connector for the backplate connection.

Veer 22.jpg

Backplate separated

Detaching the flex cable allows the backplate to be completely separated from the body of the phone.

Veer 23.jpg

Speaker enclosure

Push on the black plastic area between the two metal tabs to release the inside edge of the speaker enclosure.

Veer 24.jpg

There are two plastic tabs which hook the top of the speaker enclosure to the body of the phone. If you lever up the inside edge (the edge in the battery compartment), then these two tabs unhook very easily.

Underneath the speaker enclosure

Underneath the speaker enclosure is the camera, the rocker switch for the ringer mute, the vibrator, and a couple of antenna connectors.

Lower antenna enclosure

These look like they may be tabs that hold on the lower antenna enclosure, but they are not.

Veer 33.jpg

This is the corner leverage point to unhook the lower antenna enclosure.

Veer 34.jpg

Lever it up from this side first.

Veer 35.jpg

The other side will come off easily.

Here is the detached lower antenna enclosure.

Microphone assembly

There is a piece of rubber which guides the sound from the front microphone around two corners to hit the gold coloured microphone.

Veer 40.jpg

Main circuit board

Two screws which hold down the lower half of the main circuit board.

Veer 41.jpg

The lower half of the main circuit board can be raised by leveraging it away from the plastic clips at the bottom edge.

Veer 42.jpg

You also need to detach the flex cable that connects to the keyboard.

Veer 43.jpg

Unfortunately, it seems this part of the circuit board is not detachable, and is firmly connected to the rest of the circuitry in the battery compartment.

Veer 44.jpg

Looks like we need to find another way in ... so we clip everything back in place and start looking elsewhere.

Veer 45.jpg

Screen Bezel

An investigation of the other half of the device discovers a detachable screen bezel. In hindsight, this is obvious due to the existence of the white Veer model.

Veer 46.jpg

The bezel separates easiest from the keyboard end first.

Removal of the bezel exposes some new metal clips to explore.

Screen Assembly

Three clips on one side of the screen.

Veer 50.jpg

Three clips on the other side of the screen.

Veer 51.jpg

One clip at the top of the phone.

Veer 52.jpg

There is a flex cable connecting the screen assembly to the slider assembly. It looks fragile, so don't try and separate the screen from the slider assembly yet.

Veer 53.jpg

At this point, I reattached the screen assembly to the slider assembly, and decided to attempt to detach the circuit board from the slider assembly and attack the screen flex cable connection from that direction instead.

Detach Circuit Board

The circuit board can be detached by breaking the glued bond between it and the slider assembly.

WARNING: This is the point at which you are likely to damage something. If you are just "taking a look inside" you should stop at this point, as there is a real danger of damaging the main circuit board if you proceed past this point.

There are a number of places where the circuit board is bonded to the slider assembly. You can see those places in the next set of photos (they look like pieces of double sided tape on the rear of the circuit board and the rear of the slider assembly. It is not easy to break this bond - it requires a significant amount of force and ends up bending the circuit board to a degree where internal damage to the circuitry is very possible.

The next four shots show the circuit board separated from the slider assembly, but still attached to the screen via the flex cable.
