Did you use external micro sd card as it is necessary to backup your data.
And how much data you have on internal sd since you say nearly full.

Did you see any message of success backup and success conversion to ext4 before it boot into recovery mode

The error message you stated is normal

I don't think you able change to ext4 without external micro SD card.
Unless you want maintain RFS, then you able and success flash using modaco kernel without micro SD card.

First this function must be enabled by your telco or it could be  already auto enabled. AFAIK it can only be applicable for postpaid accounts

You can do this at : Settings/Call Settings/Call Forwarding - there are 4 options to choose ; just key in the number you wish to be diverted. You will receive a successful message immediately if activated

I forward ALL my calls to a mini small 15 year old Nokia phone. I find this very convenient without worrying about how to take the call especially when driving and on the move. I can return call on my TAB or my Nokia as I wish.
I am on postpaid Celcom and every call divert to my Digi Prepaid I just need to pay 10 sen per call divert irrespective of time. I was told if divert from Digi to others - call charges based on time is applicable. Maxis - not too sure. Go and find out if you are using Digi or Maxis

Yeah man, planning to sell it since i already own 1

Stop put hope on it, change others telco plan, i wait for Digi for 3 months last time, still no stock. i change to ask celcom, 3 days got it 

Hi Benny, good try of this ROM. I may try this after read from your result.
Most of the time, i'm not dare to flash beta or unstable ROM avoid big issue might occure.
BTW, i quite satisfy my surrent TAB with:
Overcome 1.1.3 + richardtrip Kernel V15 with Voodoo Sound 

No any problem found by me, maybe not really do the 'stress' test or fully utilize all the functions of TAB.
You advice to try Modacp Kernel if need stable kernel.
main reason I like this kernel is not the overclock CPU function but the smoothness and I more impress is the voodoo sound.

YES definitely. klwong99 is using the same kernel . Make sure you do a nandroid backup from recovery first in case you don't like it - you can just use recovery to restore back to the last default status

Thanks for your explanation, I am using Maxis.

I did follow the step on your post #4, but still can't retrieve MMS in my SGT. But I put my sim card to another handphone & it can retrieve the MMS, so must be my SGT setting goes wrong.

I think I will send it to maxis centre & let the staff there to solve it for me. Else, I need to send it to Samsung Service Centre. 

lol save ur space benny hahhaa..jk..a,way i always streaming from tab coz lazy to connect tab to pc lol..i also used to try astro file manager but need astro smb module..but really dun like their interface ..make me pening then s,times if u click not supported file got hang

I use overcome V1.1.3 plus 1.4ghz oc v15.. undervolted like this:
1400Mhz: 1450 - 100 = 1350mV
1200: - 100
1000: - 150
800: - 150
600: - 100
400: - 100
200: no changes
100: no changes

Battery temperature while idle 30deg celc.. on charging 40 deg celc..
battery life is very good.. just a bit, around 5% faster drainage comparing to modaco ext kernel..
Plus oc kernel have voodoo sound FTW..
quadrant score 2100.. 

hmm.. temp sensor not working i suppose.. go to tichardtrips thread in xda to downloa v12 if you cant go with v15..
