最近大家都在升级1.3吧. 升级前需要把先前安装的补丁和主题统统去掉.
3 u' t& W6 S* h& O% q9 X' [3 N! T从前1.1升1.2的时候, 我是土鳖的直接手动一个一个去掉的.$ d" P$ y$ p+ O% _) g- I
今天升级1.3前, 下载最新版的webos quick install 2.9.* Y8 B4 i- w' }$ a
在新版中我发现了这样一个按钮: "EPR"6 S  Z, K% y7 X7 C. P, Y
开始觉得有点眼熟, 在哪里见过, 但印象不深了.
1 E# y% a& G! `4 v0 a4 L& Vgoogle之后发现EPR=emergency patch recovery. 这个可以用来一次性去掉所有补丁.
& s  @+ z( }/ p+ H! j6 U# x9 i不知道我土鳖了没有, 以前记得在preware里面看见过这个epr, 但他要求先卸载theme, 我嫌麻烦, 就没理他.. X6 s$ l4 Q' t5 F
今天趁着升级的机会试了一下, 确实是个不错的补丁. 一键确实可以去掉所有补丁.7 y7 w1 e) N  Z8 ~2 p. m

% C8 _9 X- {" V9 J也许是我土鳖了, 直到今天才发现这个patch.

Preload很久前就有了。preware是新版本才有了这个去补丁。建议升级前先运行这个。

这里也有类似的描述, 具体如下:

Before updating to a new version of webOS, it is very important tofollow certain procedures. Here is an outline of the recommended way toupdate your webOS when you use Patches (and/or Themes) installed via Preware. Deviating from this procedure could cause unwanted results.
  • 1. Open Preware and select Installed Packages.
  • 2. Remove any Theme(s) you have installed. There SHOULD only be one...
  • 3. Go back to the main menu and select "List of Everything" and search for "Emergency".
  • 4. Select and install "Emergency Patch Recovery". Note: This will remove all patches. Please read the description.
    • After it completes (might take a couple minutes), choose"Update Feeds" from the App Menu (top left corner). Then go back tomain menu and "Installed Packages".
      • If "Patches" IS NOT listed as a category, go to step 5.
      • If "Patches" IS listed as a category, select it and remove any patches still installed. Then continue to step 5.
  • 5. If you have Luna Manager installed, start it and "Restart Luna". If not, reboot your phone.
  • 6. Update webOS. :)
  • 7. Fire up Preware and bring down the App Menu (top left corner).
  • 8. Select Update Feeds.
  • 9. Continue on to reinstalling your Patches/Theme.
  • 10. Thank the webOS-Internals group!

4 T( m6 `1 R& x4 RFor advanced users: You can dump a list of installed packagesusing the following technique before running the Emergency PatchRecovery (EPR) tool. This assumes you already have shell access to youryour Pre via novaterm or ssh.! y# l. w& y& ^+ ]8 t" Y  z
  • 1. Ssh into your Pre (you do not need to adopt root privileges)
  • 2. Type (no quotes) "ipkg -o /var list_installed | greppatches". This will display the list of patches applied to your Pre.You can redirect this output to a file or copy-and-paste it from yourshell window.
Special thanks to dbSooner on the #webos-internals IRC channel for proposing this method. 5 T0 p$ O! n$ p: T  ~1 }
