  1. 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?

      1. 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 can easily find what you need in luck

    1. 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.

          1. I checked this link but there isn’t service manual. I don’t want USER MANUAL. I’m looking for SERVICE MANUAL (included the electics schematics).

  2. Hi, I noticed that on the second image of motherboard, with chips description, the Intel pm 88818 chip is marcked with wrong color squear!

    1. 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

    1. 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.

  8. 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.

  9. 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.

  10. 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… 🙂

    1. 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.

  11. 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.

  12. 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).
