First, my device failed to get the OTA Update because I deleted some system apps (see my original post).
Then I found this post where another user restored original APKs in /system/apps and managed to manually update to JB by downloading the dlpkgfile in this post.
So I proceed, restored my /system/apps (with 755 permissions), rooted with OTA RootKeeper and SuperSU, placed the dlpkgfile and command files, restarted to fastboot (Power+Vol Down) and entered Recovery mode.
The green android with the blue progress bar went for over 10 minutes, then ... the android with the RED TRIANGLE appeared
After a minute or so the device restarted, an ASUS logo with a blue progress bar ran, but then it got stuck in the ASUS logo.
I'm still able to restart to fastboot (Power+Vol Down), where a message appears:
Android cardhu-user bootloader (1.00 e) released by "US_epad-10.4.2.9-20120809" A03
1. RCK: Recovery mode, when I select this the Red Triangle appears again.
2. Android: Normal android boot, gets freeze right away
3. Fastboot USB download protocol: Tried using ADB, but don't really know what it is. Here's an image of how the device appear in my Windows PC
4. Wipe Data: Already done this, seems to wipe user data, but still gets stuck on ASUS logo
Some pictures I took of my device: http://imgur.com/I13ou http://imgur.com/Jezpn
I also tried downloading .30 firmware from ASUS website and placing the Zip contents in my SD card, then booting recovery but no luck.
It's pretty awful that everything went so bad, I'm hoping there is a solution.
Anything would be really appreciated!!!
