Let's see if anybody can help me, because I'm pretty stuck with this.
I've tried to install the following ROM from xda-developers in a Sanei N10:
I've installed it following the usual procedure:
- Press Vol+ and Power to get the Recovery menu
- Select Wipe data/factory reset
- Select Wipe cache
- Install the three ZIP files: "cm10_a10_20120913.zip", "gapps-jb-20120726-signed.zip" & "n10_compatibility_1.2.1.zip"
The problem is, even though the first ZIP with the ROM installs successfully, the second one (the one with Google's apps) refuses to install, showing instead the message "signature verification failed". The same happens with the third ZIP (N10 compatibility).
So the installation doesn't actually finish. If I reboot the tablet, it runs Cyanogenmod 10, but the touchscreen doesn't work (I have to plug a USB mouse to interact with the operating system).
So what do I do to avoid the dreaded "signature verification failed" message? Just in case if it's of any help to identify the problem, I'll mention that I can see the Android bot laying down with a red triangle with an exclamation when entering the Recovery menu.
I've tried to use the ROM Manager which is preinstalled with Cyanogenmod 10, but when choosing "Flash ClockworkMod Recovery" it says that "The SD Card needs to be mounted to use ROM Manager". Of course my MicroSD is properly mounted (I can see its files in the card from console, from the "Terminal Emulator"). I think this happens because the MicroSD is mounted in /storage/sdcard1 instead of in /storage/sdcard0, but I can't change that. I can't download APKs from the browser, either, because it also says something similar about not being able to access the SD (even though it's correctly mounted and I can see it mounted from Settings > Storage).
I've also tried the CyanogenMod A10 ROM available in this page, which is more recent (October instead of September): http://www.slatedroid.com/topic/3870...mod-10-tweaks/ But the same happens.
I've even tried installing the CWM Recovery ROM, but it doesn't let me installing that from the Recovery either (same message about the "signature"), and with Odin3 it doesn't work either because I don't know how to reach the "download mode", which is needed for Odin3. Pressing Vol+ and Power I get the Recovery, but not the Download mode. Does anyone know how do I get to the download mode in the Sanei N10?
Any idea about how to solve this? Right now I have a tablet with no touchscreen and not even Google applications (so I don't even have the Play Store), so it's practically worthless (at least the WiFi works). How can I get this tablet back to being usable?
