In this guide, I’ll explain how to disassemble the Asus ZenFone 2 to remove the back cover, battery, camera, and motherboard.
Teardown is what we do! Follow us on Facebook for the latest repair news.
The Asus ZenFone 2 back cover is removable. There is a slot in the lower right corner of the fuselage, so it can be easily removed.
1. Removing the back cover
The back cover is made of PC + ABS material, which is flexible. The bottom is marked with the Intel logo, which means the Zenfeone 2 uses an Intel processor.

6. Removing the battery
Remove the Asus Zenfone 2 battery. Because the SIM tray is fixed to the battery, replacing it is a bit of trouble.
Micro SIM and Micro SD were fixed on the battery.
The Asus ZenFone 2 battery replacement guide is very easy. To replace the battery, you need to remove the SIM card tray module, which is fixed to the battery with glue.
ZenFone 2 uses a 3.8V 3000mAh lithium polymer battery. Model: C1191424, ATL cells.
7. Remove the motherboard
Remove the rear-facing camera, front-facing camera, and earpiece.
The motherboard is manufactured by Taiwan COMPEQ. The front of the motherboard integrates a light proximity sensor, 3.5mm headphone jack, rear camera, front camera connector interface, power supply, and lock key button. The back of the motherboard integrates a noise-canceling microphone and LED lights. Intel 64-bit processor and 4GB RAM were packaged together.

Is the headphone jack detachable from the mainboard, and can it possibly be replaced?
Have you managed to get a replacement? If so could you point me in the right direction to get one?
How to replace the screen Assembly?
I already cracked the screen and need to replace it. Can you post a guide for this?
SAME!
Lol. It uses a Qualcomm Quick Charge 2.0 chip, which is strange. It’s the SMB1357 one.
I have no signal on SIM1. How to fix it?
To fix this question, you should contact Asus.
The battery is nearly impossible to remove, it is completely glued to the phone. We punctured the battery using something sharp to try to remove it. We can’t find a replacement battery anywhere. Do you have any sources for this battery to be purchased?
Hey Leslie, I had the same problem. Did you find a battery replacement? Thanks
You can buy online and make purchases. Visit Lazada. You can also Google the web to find suppliers for the battery. One of my favorites is lelong.com. You can easily find what you need there. Good luck!
I may have found one: http://www.asusparts.eu/it/Asus-0B200-01370000. It says it’s for both the Ze550ml and Ze551ml. I didn’t try it, though. Is it hard to remove the battery with glue?
That is not true; the battery is not glued down. Rather it almost falls out once you take the screws out (there might be a piece of double-sided tape which you have to gently release. But do be very careful not to puncture the battery; it is only wrapped in foil!
Replacing the screen takes about 2 hours from start to finish. Note that the digitizer and screen are virtually impossible to separate. Don’t try to save $12 by purchasing only one of them; buy them as an assembly (about $25-35).
You’ll need a heat lamp (or bulb) or hairdryer to soften the adhesive holding the screen to the mid-frame, and you’ll need about 16″ of some 1-2mm double-tape. Rolls are cheap and will last you a lifetime.
If you’re my age (60), the magnifying visors with built-in light are definitely worth the $10-12 you’ll pay for them.
Hello, I’m looking for schematics (service manual) for this Zenfone 2. Do you have it?
Thanks
Please go to Asus.com to download it.
I didn’t find the schematics (service manual) on the Asus website. Do you have a link?
Thanks
Please check this URL https://www.asus.com/us/Phone/ZenFone_2_ZE551ML/HelpDesk_Manual/
I checked this link, but there isn’t a service manual. I don’t want USER MANUAL. I’m looking for SERVICE MANUAL (including the electrics schematics).
Thanks for your help
Hi, I noticed that on the second motherboard image, with the chips’ description, the Intel PM88818 chip is marked with the wrong colored square!
How did you remove the metal cover of the Broadcom BCM43531A1 (GPS, Glonas) chip? It seems to be soldered to the motherboard.
My phone has been in the water, and the GPS does not work. I have to fix it.
Thanks
Just use a little violence, but can not be restored after removal.
I have the ZE551ML version and every time the screen gets warm enough, it starts moving itself. What should I do to fix it?
But temporarily, it can be fixed using an electric lighter by clicking it on the screen.
It appears the LCD is affecting the digitizer by heat or pressure.
To solve this, you need to leave the screws on the cover a bit loose, but please some thin foam under the cover to keep the parts firm.
In fact, it seems the screws on the cover are creating an uneven gap between LCD and the digitizer.
Loosening the screws improves the problem, and a bit of thin foam in the proper points keeps parts safe.
I disassembled my Asus because the acceleration sensors got stuck. I removed the battery, but that didn’t work. Then I assembled it back and hit it hard, which solved the problem. Now, when connecting through USB, the phone charges, but it is not recognized by the PC. I’d appreciate any help.
Thanks!
I fixed it, I realized I bent one small wire and was not making contact. Thanks!
Hi, it appears that the SIM card flex cable connection to the USB board is loose. Try lifting the connection bar and resetting it again.
It seems the connection between the Flex SIM card holder and the USB board is lost. Please rest the connection and double-check.
I have broken the power on button for the Asus Zenfone 2 Z551 ml mobile. It has lost its shouldering point. How can I fix it through any alteration? Please send it to me on my WhatsApp at 7789202997. Please, it’s very urgent. I’m also a mobile repairer. But I don’t have its circuit. That’s why I’m asking you.
My phone battery is stuck at 50%, and to turn it on, I need to plug in the charger. When I unplugged the charger it will soon turn off again.
I charged it overnight, but the battery level is still at 50%. I also need to plug the charger in to turn it on.
This happened after I forgot to charge my phone and drained the battery to 0%.
Hey, I know this is an old post, but I recently received a Zenfone 2 Z008 from a friend. However, the flex for the charge port was not properly set, so I managed to fix it, as well as the camera position. BUT here is what happened: I accidentally ripped the antenna port cable on the big board, and now there is no signal showing for both SIM cards. Is there a way to fix this without replacing the motherboard? Thank you in advance.
Hi, you might be out of luck with this one, but you can try something as a last chance.
If you look at the antenna port closely, it has a center. So, if you unshield the cable and try to solder the center of the cable to the same point the cable connection port came off, it might work. It is a very fine operation, so make sure you take your time. The success rate is 50/50. I hope this helps.
Cheers
Try to solder it back in, using a good magnifier and a thin soldering iron tip.
Will it matter if you solder it anywhere (where the port was before) because it has 2 legs on the board? You know, or it doesn’t matter if you combine and blend.
Chris
It does matter a lot; you have to place it as it was. But if you don’t know how it was, you can try turning the phone on while it is apart and putting the socket with the wire connected to the board on the contacts to check for signal.
Will try and see what happens. I read another article that you can do a jumper and connect straight to one of the transistors, but I am not ready to do that until someone can give me a clear direction. 🙂
I can’t say anything about a direct link. I mean, it is possible, but you better contact the folks at the forum where you read that information.
I did that, and it worked just fine. If I can open it later and take a picture, I’ll show it here later.
Thank you, Axle and BP. I like this phone, but coughing up $70 for the motherboard is just too much. Here in Indonesia, spare parts are expensive, so I’d have to choose between a DIY solution and buying the latest Android.
Yeah, I perfectly understand you. Good luck with fixing it, and I adore using it. Take care!
I am using a 551ml, and one of the microphones makes a lot of noise when activated, as per the test process(BoardMic test). Would that be the one on the small pc board with the micro-USB or the other one on the motherboard? BoardMic2 is fine(the one used for speakerphone mode).
