[Android Q&A, Help & Troubleshooting] duomaxwell007:
update.

Ok Im having a HUGE problem. My phone worked fine at first, then I rooted it and used titanium backup to restore all my apps from my old phone (an lg volt) to my current phone an S5... everything was fine. My phone recognized my SD card, when I plugged the phone into my PC it would show my correct phone internal storage as well as my sd card storage. Then I ran link2sd to relink all my data to my sd card... even though i didnt need to because unlike my old phone which was 8gb the s5 was 16gb and had more than enough space to run my apps without the link2sd. If I had left that alone we wouldnt be where we are now. However I didnt so here we are.

Link2sd had message saying something like "this device doesnt support /sdext and has to be changed to sdefs (i know im getting the message way wrong but it was something like that) these settings can be changed via slider". So I clicked yes to let it do what it had to do. after all if I didnt like the results I could always change back via the slider right? link2sd required a reboot after the changes were made and now when it boots after the samsung and sprint logos and before the lock screen Im staring at a black screen that shows the time and "no connection" for about 30 secs before the lock screen shows up (this didnt happen before link2sd made whatever changes it made) and the "process system not responding" message shows up. Though the only adverse affects Ive sen from that so far is when I open Gallery it stops and closes automatically so I cant even use it.

However I couldnt find said slider and now when I hooked my phone to PC it shows no external storage and reads my internal as 127MB free of 128mb (yes that right... 128 mb.. on a phone thats supposed to be 16gb). When i go to storage on the phone itself It said sdcard unmounted (as if theres not one there) and my internal storage shows 9gb used of 14gb so the PHONE knows how much gb I should have but my pc doesnt. Also if i take the sdcard out of the phone and plug it into my pc directly everything shows up on it just as it should so i know the sd card isnt broken.

So I found solutions like reboot phone in recovery and have it wipe cache. I did that.... didnt work. Then I tried unrooting the phone and factory data reset (from the phone settings not from the recovery boot). Despite doing a factory rest which SHOULD fix ANYTHING wrong with the phone, delete all apps and make it run just as it did when you got it. That black screen between logos on lock screen still pops up and I get the "process system not responding" message still appears. Now my PC doesnt see my phone at all when Its plugged in.

So I tried booting in safe mode to see if that message still comes up and the answer is yes but now my pc sees my phone (no sd card in it but I doubt it will see it if it was) however it still displays the storage as 127mb of 128mb

So link2sd started this whole problem and factory reset wont even solve it. Ive provided plenty of details. Can this be fixed or if my phone pretty much done now (i can still use it for texts and calls but, its useless hooked to a pc, doesnt recognize external storage anymore and I cant use the gallery sooooo yea. I hope someone has a solution.
