  • It is of utmost importance that you do not attempt to free the battery from the device at this point without proceeding to the following step! This is an integrated battery that can easily be damaged or destroyed if the proper steps are are not taken.

It doesn't mention you have to remove SIM tray first.

I used the #0 for the rear panel screws. The #00 is too small and will slip, stripping the screws if you're not extra careful.

where can i buy the battery??

Has anyone answered this? I am looking too.

They sell it on here, although I found mine on eBay.

Aliexpress for $9 (original)

The last three hidden screws are a !&&* of a time consumer to remove. probably you would need only a certain type of tweezers - I got stuck at midway and now I cannot get go have my phone detect the sim card either probably because the six screws are removed. I can now turn the phone back on but with no service or wifi connections are detected. This phone is a disaster!

Ivdid that too but son in law found I had reinstalled sim card in backwards or upside down.

Where did you buy the micro USB piece? Thanks a lot!

Davide Rota - Reply

EBay. I bought new battery cause old ibe was dead would not charge. Just ordered new cables fit 9.00 something free shipping. Anyway hope this fixes problem cause new battery did not fix problems.

I was able to open going from the microusb slot and working my way around. The corners are tough, though.

in my phone the battery was glued with double sided adhesive tape, only on the right side. I pried the left side up first, and carefully removed the battery. to lift the battery I used first used a suction cup(?) followed by a plectrum like tool to lift te battery, and keep it lifted

A word of caution: the back panel is harder to remove than you might think. Especially because you may be removing the *screen* by mistake. When you have a "grip" with the tool make sure the metallic border is not coming off with it, and when you have removed enough to be able to lift the panel, make sure it isn't attached by ribbons - in that case you've been removing the screen. A good idea is to gently press your finger nail against the weak plastic located between the back and the SIM slot, and going up and down and sideways until you hear a click. Then you can start from there with the opening tool. As recommended be very gentle around the SIM slot.

Image 1/3: Keep in mind that there are four hidden screws.

  • Using our #00 screwdriver, we remove the screws around the outer edge of the upper interior cover of the phone that houses the motherboard and cameras. See info note below!

The plugs are annoying to open for the first time. They're shaped like little pegs, but I was able to poke at them with screwdrivers enough to open.

Roger - Reply

the best spot to start prying the cover open is at the cable outlet for the power/volume buttons (careful not to dameage the wires)

Dangerous Pictures - Reply

A needle works best to remove the plugs.

Stan Barton - Reply

I second this. I used a sewing pin and the plugs came out in no time!

Be careful not to displace the rear camera when replacing the motherboard cover.

  • After we have removed the motherboard cover, we notice that the battery is intact and has a black ribbon attached to it, which is mounted on the logic board.

This took a ton of force to remove from the adhesive!

Also I was able to take off the cable before removing the battery.

Roger - Reply

Is it OK to use the battery if I bent it during removal? I had to 'iron' it flat, but I think it might still be useable...

Henry Annand - Reply

the best way to remove the battery is to lever the left side up from the bottom and remove it from the glue with an old credit card

Dangerous Pictures - Reply

Do this! it comes up very easily this way. All the adhesive is on the right side.

Daniel ONeill -

Great suggestion with a card to remove the battery!

Jeff Mack -

I second Dangerous Picture's suggestion. I found it very helpful to remove the ribbon from the dock (it was easy to do) before trying to remove the battery.

Stan Barton - Reply

  • Once the battery has been freed, we use the ever handy black spudger to pry up and free the the battery ribbon from its dock. Success!

For step 4, the connection to the battery should always be done as soon as possible so after removing the back plate to the board would be ideal.

Otherwise, very thorough so far!

Duc - Reply

Thought I was going to snap my battery in half but patience and slight pressure did the trick.

Also agreeing the battery should be disconnected as soon as possible.

  • After the battery has been removed, use the spudger to disconnect the remaining ribbons.

the digitizer ribbon connector has a small plastic piece that blocks the connector from being removed through the slit. make sure to remove it (simple push with an opening tool). then you can remove the connector/ribbon cable.

All the ribbons came off easily after I found them, save for the volume buttons. Iended up tearing the ribbon trying to maneuver it out with the motherboard itself. Do you guys have any tips for removing the volume control ribbons? They seem to be held down by tiny extrusions in the phone.

Crazy Joe - Reply

Use extreme caution with the side ribbons. I've just destroyed my Volume Buttons as I tried to get the ribbon off.

adenoid2 - Reply

Another method for the side ribbons (power/volume) is desoldering the connectors - since I couldn't find any promising way to detach the buttons without damage I took this route and had success. Also note that you do not need to remove the mainboard and cameras for replacing the screen - a slight tilt should be enough to access the top ribbon (which belongs to the display assembly and has to be removed) so the side ribbons can stay in place.

  • After removal of the ribbons, there is one final screw. Once you have removed this, the motherboard easily pries out with spudger.

After removing the final screw that holds the motherboard in place, do not just lift away the motherboard. The antenna is fixed to the back of the motherboard in the bottom right corner. Lift the motherboard from the top, leaving the bottom part of the motherboard (the part that is nearest the battery) close to the phone body. The antenna is a black wire that runs from the motherboard around the right side of the battery recess. It is held to the back side of the motherboard by a small, round, brass-coloured connector. It can be unclipped from the motherboard using a small pair of tweezers.

Blenk - Reply

There is a little tape in the battery box keep the antenna in place.

You can remove the tape and have a few centimeters of antenna free in case you accidentally disconnect it.

It is !&&* of a fiddeling to connect it again but it is feasible

The final screw is a Phillips 000

Jan Seidel - Reply

After my second assembly replacement I realised it is not necessary to completely remove the motherboard. Just lift it from the top enough to navigate the top ribbon on the assembly through the chassis and therefore avoid any possible damage to the power and volume flex.

  • Once the motherboard has been removed simply pry off the rear facing camera with a spudger or angled tweezers.

you don't need to remove the front or rear camera - once the motherboard is free, nothing else has to be done to it.

fudgyhoops1 - Reply

The camera may fall off as the connector is pretty slack.

You don't have to remove it but be careful not drop or lose it
