how long does this usualy take? mine's been sitting at "installing muti-CSC" for about 5 min now.

it gets better: I gave up and rebooted, and it didn't work, so I tried again with auto reboot disabled, this let me catch it on the first boot and get the CSC updated properly... for some reason none of my apps were wiped so i'm now factory resetting as it was FC city... now on to JMA then JMC, once more into the breach my friends.

this process worked for me.
I'm on the TMobile Tab, original ROM was: JJB.
I first installed JM6, with Odin. I just flashed the Rom (pda) part with repartition selected. In fact, I forgot to select the CSC & modem parts. After the first reboot (with lots of FC's), i flashed the dbdata.
At this stage my CSC and modem did show blank and only PDA showed JM6.
I then flashed JMA, without repartition and after the reboot and boot into recovery, all three entries showed JMA.

Then I followed the instructions just as given, and flashed JMC. Reboot into recovery and it rebuild the dbdata and factory reset once more.

Everything is working fine.
I have JMA, JMC, JMA when I do *#1234#

I'm using an AT&T simcard on this TMO tab and can make calls just fine.
Although I only get Edge, I mostly use the wifi, anyway.

Thanks for the great, detailed process description of how to install JMC - it really helped me a lit and the confidence to flash my tab for the first time.

I believe this can also be done from recovery.

Actually, once I messed up I could not get to any recovery. I was lucky that I managed to boot Android into some kind of state. So to be on the safe side I'd recommend to do factory reset before any flashing.

Can I go directly from JM6 to JMC, therefore skipping JMA, or is it better to just do it sequentially?

A word about wiping data: I had my Tab fully set up with original AT&T firmware and then I started installation I got into lots of trouble. Instead of recovery mode it went into blank screen with vertical white line (I suspect it did dbdata update behind it though), then it rebooted and my apps started crashing.
The only way to fix it was to get to setting and do factory reset. After that everything went by the book.

So you may want to clarify that data must be wiped from Android, unless you have some other way.

Thanks again

do you still get the white line after the reboot
