The short story is my 7cG2 running nano rev14 is stuck without an unlock slider on the opening screen, asking for a sim card which it won't recognize as it is also in airplane mode.

How it got there is as follows;

I have 2 7cG2's the other is running glob_V3. I will call them V3 and rev14.

Today I used clockwork mod to install a backup on V3 for which I could not remember the rom. It was rev14 and worked properly. I then successfully restored the V3 tablet back to V3.

I then factory reset the rev14 tablet using settings/privacy. Next I used the same rev14 backup installed earlier on the V3 tablet to restore the rev14 tablet as I do not have a newer backup.
It would not open without a sim card (no unlock slider) the unlock slider appeared after inserting sim card, and the home button did nothing. I restored the backup again with the same result.
I then used clockwork mod as follows; factory reset, wipe dalvik cache, format system, advanced restore system only from an earlier backup of rev14. I presume that backup must have been in airplane mode, and that's how I got to where I am now.

The tablet will go into safe mode. I am writing this from the beach in a Malawian village, access to a PC would be difficult

Hi Globula,

I presume fastboot needs a PC and adb. The problem is that a download speed of 30Mb per hour is really good. To install the programs on a PC would take several days, impractical at an internet cafe.

The problem started when the first restore would not show an unlock slider without
sim card. Now, as is normal I think, if the 7cG2 is rebooted in airplane mode with or without a sim card in, it will not recognize it. Airplane mode needs to be turned off, followed by reboot. Long press power button only offers the power off button for me.

The tablet is running, my anti virus programs (3) appear in the notification bar, but I can't access them remotely because of airplane mode!

Oh dear, an awful amount of work to type fastboot -w!

Hi Globula,

Thanks for the download link, and for your quick replies.
I have now disconnected the battery for the night, I will see what happens!

I did a separate system format using clockwork mod before the last advanced system only restore, tablet behaviour did not change except that the backup I chose presumably had airplane mode on. I often use it to save battery.

New question. Please re-post if it is in the wrong place.

I intend install DC2SD.

I will partition the new 8Gb class 10 sd card Ext4 using clocwork mod.

Can I install by copying the new boot and recovery files into an existing backup?
Could I use DC2SD on your Glob_V3 rom, how would I install recovery. Copying into an existing backup?
Would my old backups still work?

Can I update clockwork mod (the lastest version has smaller backups). Or could I do it myself, by saving 1 copy and deleting all others from the same rom, of boot, recovery, and system, replacing if I want to restore a specific backup?
