求大神帮看下怎么恢复误删并 push 的文件（附操作记录）

真是No zuo no die。
前段时间刚上手git，就用来部署线上代码。
其实这段时间还都挺好的，不用每次修改都scp。

但今天不知道怎么会删掉了一些文件。
开了ss，Gist还是打开很慢，各位将就看下我的操作记录吧

我的思路很简单，服务器运行这么些天，增加了不少图片，是没有放进远端仓库的。
先在服务器端git commit -a了这些图片，然后本地仓库git pull，本地修改代码后git commit -a，然后本地git push。不知道我思路哪里出错了。。（没错，我按照svn的思路了。。）

操作记录如下
服务器:

1.git commit -am 'update';
确实有几百张图片加入仓库了

2.git status
# On branch master
nothing to commit (working directory clean)
说明已经没有新的改动了

本地操作
1.git pull
remote: Counting objects: 254, done.
remote: Compressing objects: 100% (206/206), done.
remote: Total 206 (delta 20), reused 0 (delta 0)
Receiving objects: 100% (206/206), 12.70 MiB | 76.00 KiB/s, done.

From xxx:/www/web/xxxcom/
51c91d8..fe6c6c6 master -> origin/master
Updating 51c91d8..fe6c6c6
error: Your local changes to the following files would be overwritten by merge:
public_html/data/config.inc.php
public_html/data/tasks.inc.php
Please, commit your changes or stash them before you can merge.
Aborting

因为config.inc.php，tasks.inc.php是数据库配置，我之前用git undate-index --assume-unchanged file忽略掉，所以提示Aborting

2.修改bug，然后git commit -am 'fix images not show in detail'
[master 5aaf3a2] fix images not show in detail
4 files changed, 19 insertions(+), 4 deletions(-)
没错，是改了4个文件

3.git push
To xxx:/www/web/xxxcom/.git
! [rejected] master -> master (non-fast-forward)
error: failed to push some refs to 'xxx:/www/web/xxxcom/.git'
hint: Updates were rejected because the tip of your current branch is behind
hint: its remote counterpart. Integrate the remote changes (e.g.
hint: 'git pull ...') before pushing again.
hint: See the 'Note about fast-forwards' in 'git push --help' for details.
失败了，猜想大概是因为本地git pull Abort的那2个文件

4.git push -f origin master
尝试性的这样提交。。然后就悲催了
Counting objects: 21, done.

Compressing objects: 100% (10/10), done.

***
remote: HEAD is now at 5aaf3a2 fix images not show in detail
To xxx:/www/web/xxxcom/.git
+ fe6c6c6...5aaf3a2 master -> master (forced update)
然后服务器上的remote: D的文件都删除了。。。
我想不明白，本地也没有删除啊，怎么就push会有呢？

5.git status
On branch master
Your branch is up-to-date with 'origin/master'.

本地仓库，远端仓库项目目录已经备份（吃大亏了，必须这么做）。

尝试解决方法：
1.我尝试性在服务器目录git log

commit 5aaf3a2ea32bb30cf367dcf713a2031dee00f75e
Author: xxxx <xxxx@xxxx.com>
Date: Mon Apr 14 17:04:37 2014 +0800

fix images not show in detail

commit 51c91d833a62709713d6ff1be6f48aa3ec14fe4a
Author: xxxx <xxxx@xxxx.com>
Date: Fri Apr 4 14:36:00 2014 +0800

fix htaccess

居然没有17:04:37前的 'update'，费解。。。

2.单个文件也尝试过，没用
git checkout deleted-file
#error: pathspec 'deleted-file' did not match any file(s) known to git.

3.git ls-files –deleted
没有删除文件

弄了一晚上，没找到解决方案，烦啊。

请问下该如何恢复，或者可以尝试哪些方法恢复。麻烦写清楚点步骤。。

回复均送金币。
只能以此为报，
不能捡肥皂。

谢谢大家看完这么长操作记录。
