Teardowns I've Worked On

Questions

Answers

  • Answer to: Where is the NFC antenna?

    Just worked this out, this is for iPhone 6, however iPhone 6 plus should be similar. The NFC antenna is the top bezel itself, the top bezel has 2.4G(wifi and Bluetooth), cellular diversity, GPS and NFC. The main feed point for GPS, cellular and 2.4G is the screw boss under the plastic add-on antenna, with a "grounding bracket" attaching it to the bezel. The plastic antenna serves as the 5G wifi antenna. The NFC antenna feed point is the screw boss next to the camera and sleep/wake button, with a flex cable under the camera bracket serving as signal conductor. There is an additional feed point in the middle of the bracket, it does not connect to any wireless services, however it connects to a dynamic switch to tune the top bezel dynamically to serve different bands. The F-shaped flex cable on the back of the board is JUST a bridging cable, not an antenna in any way.
  • Answer to: Can I upgrade the RAM?

    No, you can't upgrade the RAM. My 2010 MacBook Air has 2 GB of RAM and runs OS X Yosemite just fine, there may be other issues preventing install.
  • Answer to: home iPhone6 home button replacement will id still work

    No, Touch ID will die immediately and if you try to restore/upgrade iOS, the phone dies altogether.
  • Answer to: Motherboard Connections To Frame

    No, Those are just antennas.
  • Answer to: *IMPORTANT! HELP!* Antenna problems

    Next to the rear camera bracket.
  • Answer to: Reprogramming the NAND Flash and device ID on iPhone and iPad

    If there is no factory activation log on the server, Apple simply refuses to activate this product altogether, so just making up a new device ID cannot work. You can swap chips from another clean but broken device and assume identity of that device to activate, however you have to swap all major chips together since they are encrypted and matched to each other on both local and server end. Breaking these pairings will likely result in refused activation or immediate bricking. However there has been recorded events of new (not icloud locked) devices been locked by someone else, because iPhone 4 has been hacked enough to reprogram IMEI and other internal IDs. So malicious users can obtain IMEI/serial pairs, use the hacked iPhone 4 to trick icloud to lock other new and not locked devices, then scam money from the victims.
  • Answer to: Cellular Antenna Connection Location

    There are at least 3 antennas for cellular connection and at least 2 are used simultaneously. The lightning flex with the bottom bezel is primary Rx and Tx antenna, the top bezel itself is NFC, GPS, diversity Rx and secondary Tx antenna, maybe also for Bluetooth/Wi-Fi but I'm not sure, The antenna on the top left is like the top bezel, but I'm not sure how those two share the tasks.
  • Answer to: Capacity issues on 16GB iPad mini 2 (WiFi + Cellular)

    Because system files take up space.
  • Answer to: 2 TB time capsule

    Probably just tripped by a surge, check your power outlets.
  • Answer to: iPad mini LOCA Glued?

    No, not for ipad mini. However Apple glued ipad air 2 and imac, so you don't know about crazy.

Notes

  • LG Watch Urbane Teardown

    Just replace the entire case with the display, it's pointless to peel them apart.

  • Retina Macbook 2015 Teardown

    Just replace the bottom case with the battery together. I don't see why you guys are so determined to pull the battery off the case when replacing it, it's just a cheap stupid metal bottom.

    Also pentalobe screws are no longer "proprietary" when you can get 10 for like 1 dollar.

    Apart from those. I agree this thing gets no more than 1 score on repairability though

  • Retina Macbook 2015 Teardown

    Just don't pull the battery off the case, replace those two as an assembly.

    Speakers and antennas are not so expensive either, but they are easily removable so not a problem.

  • iPhone 5 Display Assembly Replacement

    The compass is right next to it.

  • MacBook Air 13" Early 2015 Teardown

    Because nothing changes

  • iPhone 5s Home Button Assembly Replacement

    Unfortunately this will never work, the sensor is paired to the logic board. If you want to replace the defective tactile switch, remove all the plastic/rubber parts on the flex cable and resolder a new switch or disassemble the switch and clean/replace the metal dome switch. If you want to repair fingerprint function, just give up.

  • iPhone 6 Plus Home Button Assembly Replacement

    This guide is pointless, iPhone 6/6 plus home button is not replaceable, period.

  • iPad Mini Wi-Fi Teardown

    ipod touch and iphone 5 also have these plates. for structural and shielding purposes

  • iPad Mini 2 Teardown

    iPads are a pain in the !@# to repair, especially the glued up part and the open-up-and-wreck-up foam gasket around the LCD. I would have given that only 2 scores too

    But the Ifixit guys are a bit old schooled. They still believe the pentalobe screws are bad for repairs. Now the screwdrivers are $1 each. So much for 'proprietary' screws. And I actually support the trend of bonding the glass to the LCD. This actually toughens up the display module and eliminates dust under the glass panel. Which is a major headache when you open up the device to repair it

  • iPhone 5s Upper Component Cable Replacement

    This is actually the GPS/cellular DRX antenna connector, don't screw up.
