Fixing a flooded iPhone 6 (or any other phone)

Your iPhone fell in the water and no longer works? Here’s how you might be able to fix it. My girlfriend had dropped her’s in the toilet (don’t ask how) and with a bit of patience and some chemicals I was able to get it working again. This little trick might also work with any other kind of electronics.

  1. Take your phone apart completely. iFixit has some very well made guides for most iPhone models. (If you don’t have the proper screwdrivers, spudgers, suction cups and things, Ebay is a good place to get them, they only cost a couple of dollars.)
  2. Take the logic board out.
  3. Look for water deposits and corrosion (bluish/greenish spots) on the logic board and everywhere inside the phone.
  4. Put that logic board and every other part that’s been exposed to water in a plastic container.
  5. Pour a generous amount of isopropyl alcohol (the higher the concentration the best) in the container so that the parts are completely submerged.
  6. Let them sit there for a couple of days, intermittently shaking the container to swoosh the alcohol around.
  7. Get a soft bristled toothbrush, dunk it in the alcohol and gently brush off all the corrosion that you can see. Pay extra attention to the connectors and the logic board, inspect them meticulously and clean them thoroughly.
  8. Let the parts dry for two or more days. (You can put the alcohol back in its bottle.)
  9. Put the phone back together, working in reverse from the guide you used originally to take it apart.
  10. Plug it in and hope for the best.

Hope this helps… If you have any other suggestions and if it worked with your model of phone or electronics, I’d appreciate it if you leave a comment.

Partitioning an Ipod to FAT32 and ext3

I recently inherited my sister’s “defective” (but fixed for 5$) 120GB Classic Ipod and managed to partition it the way I wanted. It was not a trivial process so I tought I’d share my experience with the web so others can benefit from it.

My music library is far from being 120GB so even if I feed the Ipod all my tunes, I’d still have a lot of free space on it. Granted, you can mount the Ipod as a mass storage device and stuff the rest with anything, but here’s the catch: Ipods will only format to FAT32 or HFS+ file systems if you use iTunes. As a consequence, if you pick HFS+, you will not be able to use them on windows and some *nix (if they lack the HFS+ support module) and if you choose FAT32, backup solutions such as backtintime will not work (they need a journaling file system).

So I took to partitioning my Ipod with two different partition using a different file system for each, FAT32 and EXT3. I tough it would be a simple task, but turns out that it wasn’t. Just formatting the Ipod and letting gtkpod rebuild it did not cut it; the device would stutter, only play the first few seconds of each track and give off artifacts while displaying the CD covers. And when plugged in iTunes, the software would report the device as corrupted and offer me to reset it. I thought that gtkpod must be missing on something so I should use iTunes instead yo rebuild it, but iTunes would still ask me to reset my iPod. Here is what worked after a fair amount of tinkering:

  1. Reset the iPod with iTunes (on a different computer since this tutorial assumes you are using a *nix).
  2. Plug it on Linux and run the following command on the user partition. My Ipod is a 6th generation classic, there is no partition for the firmware, it sits somewhere on the MCU flash, but it appears that older Ipod use a firmware partition so leave it alone. Paying attention to that particularity, here is the commands you need to run:
    1. Unmount the plugged int Ipod with umount  /dev/sdXY Where X is the device letter of your Ipod and Y is the partition number.
    2. dd if=/dev/sdXY of=ipod.bk bs=512M Where X is the user partition of you Ipod and Y is the partition number. This will effectively copy 512MB of raw bytes from you Ipod partition and save it to the ipod.bk file.
  3. Next, take your Ipod and format it the way you want using fdisk. If you have a firmware partition, do not destroy it! Keep the following points in mind:
    1. Use a Master Boot Record (MBR)
    2. All partitions should be primary
  4. Finally: dd of=/dev/sdXY if=ipod.bk bs=512M Where X is the user partition of you Ipod and Y is the partition number. This is going to copy back that 512MB file we extracted earlier from the Ipod, setting that partition the way it was before the repartitioning.

Voilà! Plug your Ipod in, upload music with you favorite app and do backups with your file system of choice. Mine is happily working with that setup: Ipod stuff on FAT32 and backintime on EXT3.

The quirk I got with this technique was that both iTunes and the Ipod report the full size of the internal hard drive as being available for music while in reality its not; it looks like the firmware keeps a record of the empty space withing the files of the user partition (why it is not computing it is anyone’s guess). You should probably be careful not to fill it up to a point where the two partitions would overlap (although that should not happen if the firmware is paying attention but then again, not tested).

Enjoy!
