So first I rooted the tablet, that worked great. it is running version 75
and i was playing around and deleted some of the key apps (whoops) like T9ChineseIME, etc
Then I installed the very first CWR port, boots fine to that.
Then I tried to update the tablet with the official updates, obviously they fail.
Then I found the updates ported for CWR, but they also fail because some of the key apps are missing (initially, FlexT9ChineseIME.apk).
So I downloaded the app dump and tried to copy it back to /system/app but it keeps failing
So here's the part that has me stumped. I can't get /system/ to mount as writeable. I have superuser installed, and superuser is reporting that ES File Explorer is getting root access. I downloaded an app called "Mount /system" and it reports /system is mounted as rw, but i still cant get ES File Explorer to write to anything in /system
As far as I can tell, the system is borked because of all the fiddling I've done. Is there a definitive way to get the boot recovery restored back to the stock Lenovo one instead of CWR? Or a solid way to restore the local memory to stock? or even just the /system folder?
this is a 32gb TPT USA model, no 3G

You can mount /system as read/write in an ADB session;
mount –o rw,remount /system
Copy and paste the above. Your setup is far from borked if you can still use the tablet. IIRC, it's two files (<appname>.apk and <appname>.odex) you'll need to copy to /system based on the <appname> the update says it can't find. The app doesn't even have to be installed.

Seems like I was able to find a nanroid image backup from another helpful user and restore that using the existing CWR i had installed. i'm applying an update right now (0086 CWR as posted on this forum) and seeing how that goes...

Like you, I made a mistake too removing some Lenovo apps. I used a rooted uninstaller, removed Launcher2.apk (I think) which if I remember correctly, was aroun 60 - 70 Mb size. Now the log-in screen is gone. I cannot use the tablet at all. Before this I had the tablet up-to-date, OTA2.5 0089 I think.
The most up-to-date nanroid backup image (OTA2) I can find online contain an Launcher2.apk of 49.3 Mb. I copied it to /system/app/ folder but it kept force closing. Cannot use it.
I wonder if you or other user are willing to share the Launcher2.apk to me after you have updated your system to OTA2.5 (latest). Much much appreciated!
As a negative example myself, i think it is better not to touch Lennovo apps.

Thanks for the link. lenssd9.
I looked into it but I was afraid to apply it because I cannot figure out how it works...
My problem is that I uninstalled Launcher2.apk accidentally. How can I re-install it without having to log in.
I can still access the tablet from adb shell. My theory is that if I copy the correct version of Launcher2.apk into /system/app folder, it would work. Anyone has an updated Launcher2.apk (OTA2.5)?
Wish I made a backup earlier!

OK. Finally I fixed mine by replacing Launcher2.apk from a 0089 nandroid backup kindly shared by user pwstein on xda-developers.

Best best regards!
