NANDJ_ Find flash media and keep out ERROR FIX!

I had been struggling with this issue for the better part of 3 weeks until I finally found a solution. I haven't seen it mentioned here -

-In my case, my problem had started with the NAND error after putting a new screen on.

-Put the old cracked screen on and it seemed to work.

-After unplugging and plugging the new screen in a bunch of times AND doing the restore, it seemed to boot correctly.

-Once in a while the phone would shut down and boot back to the NAND error again, and after about 20 resets it would somehow 'luckily' boot correctly.

-After about 2 more weeks, it stopped ever booting correctly and booted only to the NAND screen ever no matter what I did.

-I tried to do the DFU Mode / Restore thing again since that had worked once before.

-Still no dice.

-I READ ON THE GSM FORUM ABOUT THE COMPASS IC which is SUPER CLOSE to where the Front Camera Flex Cable plugs in. A user said just to remove it. I have no soldering experience so I simply pried it off with a metal clip.

-Voila, finally got passed the -4013 error in the Restore screen, and now I have a functional phone again, probably without a compass feature, but I have been trying to make this phone last as I am still under contract for a couple more months.

It makes sense to me that possibly people are damaging this tiny sensitive chip when swapping screens, and that is causing the hardware check to fail upon boot. The only thing that has changed in my phone's functionality now is that the compass app doesn't work. Maps, etc. still function fine.

Nand Flash Errors at Boot up are usually caused by the iPhone 5, 5S, and 5C Front Camera/Proximity Flex Cable. Its either a damaged cable or the connector is on incorrectly. Sometimes when connectors on wrong u will get a RED Screen of Death. Do not Panic....Just swap out the Front Camera/ Proximity Flex Cable and you will be ok.

I have also seen Nand Flash errors on iPad 4G as well. I fixed this by replacing one of the flex cables. You just have to disconnect each flex cable at bootup 1 by 1 until you figure which is bad . Then replace it.......

FYI.... On the 5S and 5C be real careful when connecting the Prox cable. The Connector is offset and may snap in the wrong way...Be Careful......

''Hey guys...As to NAND FLASH ERROR at boot.....

We have repaired over 5,000 iPhones in the last 2 years and have seen the NAND FLASH ERROR only about 10 times total. Each time on iPhone 5/5S/5C i was able to simply replace Front Camera/Proximity Sensor Flex Cable with a new one and error would go away 100% of the time..... FYI' do not panic !!!!!http://forums.imore.com/iphone-5/279618-...

Had this problem on an iPad 4 Retina... Replaced the back camera and all was fine. :)

HI GUYS,

m a mobile repair tech in australia since 7 years now and own few franchises here in same field..(repair and unlocking)

the whole thing which goes wrong while we take off the proximity cable in iphone 5 is it shorts with the lcd bezel (alluminium plate under lcd).

and secondly , what i experienced is when u take off the proxy flex from board and put it back on.. make sure u take ur time and b calm and gentle. try to use tweesers to the best possible.(non stativ ones)

i 2 iphone 5 board by changing screens with my metal screw driver and hands.. .coz of static current in human body..

NICE POST..

From my experience, it has been a broken/ripped power button flex cable. This has happened to me twice and I replaced it both times - fixing the issue.

The best way to repair your troubles is opening over your iPhone,and remove your battery connection for few seconds wait a little bit and reconnect your battery and your screen afterwards and Voila!! you should be all set...Any questions my name is Barri.

I have read many a post on this subject, I would say to anyone trying to make this repair and have little to no experience on electronics or working on extremely small electrical connections would be to spend a few more dollars.if you purchase a new Digitizer for your phone because you smashed the screen purchase one as complete as possible,one that all you need to do is swap assembly and you should be ok.Else send it out and have a qualified technician do your repair for you.If you stop and think about it you have a pretty hefty investment sitting on your work bench,is it worth the bucks you save attempting to make your own repair? I have done a few of these myself and if you have steady hands ,take your time ,be patient you will more than likely fix your phone.Don't pay attention to detail and procedure and you will put it together wrong cause more damage than you started with. These phones are very specific,for the most part the screws are so small and hard to put back in and in the correct order .In the case of the digitizer cover,4 screws,I believe only 2 are the same length while the other 2 are different lengths,put them in the wrong order and chance runing your phone.get help when you need it,be careful not to loose these screws or install them wrong,easy to do for sure.

I had the same issue. Replaced the screen and everything was fine for 2 days, then for some reason the headphones weren't working so i turned off my phone but couldn't turn it back on and had the NAND error. So I removed the front camera cable like it was recommended and it worked! Replaced the cable and the phone works like it should! Thanks!
