Is the headphone jack detachable from the mainboard, and can it be possibly replaced?
Have you managed to get a replacement?if so could you point me in the right direction to get one?
How to repalce 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. That’s strange. It’s the ‘smb1357’ one.
I have no singal on SIM1 how to fix it?
to fix this question, you should contact asus
Battery nearly impossible to remove, completely glued to phone. We punctured the battery using something sharp trying to remove it. Can’t find replacement battery anywhere, do you have any sources for this battery to be purchased?
Hey Leslie, I had the same problem. Did you by any chance find a battery replacement. Thanks
U can buy online and make purchases..visit lazada ur you just google the web to find any suppliers for the battery.ones of my fovourite is lelong.com.u can easily find what you need in there..gd luck
I may have found one: http://www.asusparts.eu/it/Asus-0B200-01370000 it says it’s both for ze550ml and ze551ml. I didn’t try it tho. Is it hard to remove the battery with glue?
Not true — battery 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 to not puncture the battery — it is only wrapped in foil!
Replacing the screen takes about 2 hours 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, will last you a lifetime.
If you’re my age (60) the magnifying visors with builtin light are definitely worth the $10-12 you’ll pay for them.

Hi, I noticed that on the second image of motherboard, with chips description, the Intel pm 88818 chip is marcked with wrong color squear!
And how did you take of the metal cover of the Broadcom BCM43531A1 (gps, glonas) chip? It seems to be soldered to motherboard..
My phone has been in water, now gps does not work, I have to fix it..((
Thanks
Just use a little violence, but can not be restored after removal
I have ZE551ML version and every time the screen get warm enough my screen starting move it self.. what should i do to fix it..?
But for temporary it can be fixed using elektric lighter by click it on screen..
It appears the lcd is effecting the digitizer by heat or pressure.
To solve this you need to leave the screws on the cover a bit loos , but pleace some thin foan under the cover to keep the parts firm.
In fact it seems thr screws on the cover is creating uneven gap betweeh LCD and digitizer.
By loosening the screws problem improves and a bit of thin foam in proper points keeps parts safe
I disassembled my asus as the acceleration sensors got stuck, removed the battery and that didn’t work. Then assembled it back and hit it hard, that 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 , you might be out of luck with this one , but you can try something as last chance.
If you look at the anttena port closely, it had a center .. So if you unshield the cable and try to solder the center of the cable to the same point the cable connections port came off , it might work … It is a very fine operation 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 to solder it anywhere (where the port was before), because it has 2 legs on the board, you know like – or +, or it doesnt matter if its combined and blend.

It does matter alot, u have to place it as it was. But if you don’t know how it was, you can try to turn the phone on, while it is apart, and put the socket with the wire connected to the board on the contacts, to check for signal.
Will try and see what happen, i read other article that you can do a jumper and connect straight to one of the transistor, but i am not ready to do that until someone can give me a clear direction… 🙂
Can`t say nothing about direct link, i mean it is possible i gues, but you beetter contact the falks at the forum you red that info.
I did that, it worked just fine, if I can open it later and take a pic I´ll show it here later.
Thank you Axle and BP, i like this phone but to cough 70$ of mother board is just to much, here in indonesia sparepart is expensivo, so either a DIY solution or buy latest android.
Yeh, i perfectly understand you, well good luck with fixing it, and adore using it. Take care!
I am using a 551ml, one of the microphones make a lot of noise when activated, per the ssmi 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).
