Cannot finish Battlefield 4 download - % complete keeps going backwards

 I have the same problem. I looked for fixes all over. Nothing works. After a couple hours of rubber banding back and forth on completion % I get an error 

"An unexpected error has occured please try later 262148:131086" 

Yea, I'm at work now, but I think I'm going to try to reinstall Origin completely and try again.  Obviously if you have a ton of games on Origin that may be a bummer.  I also saw a lot of this happening in the BETA, but I haven't been able to attempt any of those solutions.  I'm letting it run all day at 8MB/s so maybe it just takes time.  I'll let you know if I get that error or not.

Good luck I hope it works. I've tried to reinstall Origin and BF4 multiple times. 

Not one EA admin response or help even though multiple people having this issue. How can EA not even get the simplest of issues resolved that an independant F2P game has mastered. What a waste of $60

I spoke to one via message and the only solution they even responded with was to reinstall origin. They said they have no other fixes at this time.  I did that and the download went to 10% before I had to go back to work, so I will let you know if that worked.  I also selected the "Origin Beta" in the account options after I reinstalled the game.

 For an hour I messaged an EA tech help agent. We went through a ton of troubleshooting. Nothing really new except to change the download path. Nothing worked at the end he gave me a refund. Such a bummer. I was excited to play. Makes absolutley no sense because I downloaded and played the beta fine.

Im thinkin about trying a hard copy and getting a refund for the digital copy... but to be honest that may not do a thing

 Well I'm done for today trying. After 40hours it's come to this.......

you: same problem
you: wow now im back to 1%. it's like it's not downloading anything
Nabajyoti: Alright.
Nabajyoti: There are two thing that we can do now.
Nabajyoti: We can either wait for sometime and try to redownload the game. You know this game has just released. So this kind of issue is common and temporary.
you: or......
Nabajyoti: Or I can provide you another trouble shooting step if some technical issue is stopping the download to take place.
you: lets keep going. im not giving up yet
Nabajyoti: I appreciate your spirit for the game!
you: i downloaded and played the beta fine. i don't understand why this is happening
Nabajyoti: I would request you to try to download the game after sometime. Please atleast wait for 4 to 5 hours.
Nabajyoti: I would also advise you to uninstall the beta. This sometimes may cause problem in accessing the game.
you: first thing i did
Nabajyoti: You uninstalled the beta?
Nabajyoti: Are we connected?
you: yes. totally uninstalled the beta
Nabajyoti: Okay, great job.
Nabajyoti: So is it okay for you if you wait for sometime?
you: no, i've already done that. way before trying to download the first time
Nabajyoti: Well I would advise you to wait for at least 4 to 5 hours and then try to download. This issues gets fixed by themselves with time.
you: well can i get a refund for buying the deluxe edition since i can't access the game 24 hours like i was supposed to
info: Your chat transcript will be sent to [email deleted] at the end of your chat session.
Nabajyoti: Would you like to go for a refund?
you: i would like the difference of the products. $10. The digital deluxe version, which i bought is useless now if I have to wait until EA/Origin resolves the problem
Nabajyoti: Did you purchase the standard edition too?
you: negative
Nabajyoti: Please ignore the last message as it was not for you.
Nabajyoti: Okay. Are you talking about the 10$ refund?
you: Yes
Nabajyoti: I am very sorry as that would not be possible. The 10$ is a non refundable charge for the extra contents.
you: okay can we refund the whole game then?
Nabajyoti: That would likely be possible!
Nabajyoti: Do you want the refund now?
you: yes

now there's a solution that makes sense!

I had this happen several times while trying to download the Beta version. Basically what is happening is you download "chunks" and if those are deemed corrupted due to your internet connection, their servers, or somewhere in between then it will toss it. It took me forever to get the beta downloaded but eventually I was able to. Same rules should apply to to this: Just keep trying and eventually it will let you through. If not then you need to check your connection to see what your line quality is. http://www.pingtest.net/ should help you get an idea.
