It is not able to save the partition table. Yes, it is a standard error. I faced it when I was trying to do the same. But the thing was that the sdcard was not properly unmounted. And it was resolved the way I said. You can also check that the same error has been discussed several times on the thread itself.

In step 3, try unmounting in TWRP by unchecking the sdcard. It will work then

It should work then. You could try uninstalling and reinstalling the adb drivers. It could help. Well, I am not sure why this is happening. I think someone else also face the same problem. Search the thread. It might help :)

I tried again following a instruction in the original thread, which to unmount the sdcard just uncheck the sdcard and date in the mount options in TWRP, but does not work again ...

After unmounting the sdcard in twrp, don't press back. Stay on the page and continue with the process. Try doing it this way.

Start and stop cylinder of partition 14 are messed up. Start the process again. Delete the partition 14 and recreate both partitions 14 and 15 as given in the tutorial.
(Remember to unmount the sdcard from the twrp which is step 3 in tutorial.)
If you are able to save the partitions successfully after resizing, you can format the sdcard and data partitions. You can then transfer the rom and flash it.

    Reboot the phone and press the Volume+ button when the led flashes to enter into recovery. Now stay there...connect the phone to your computer. Open command prompt in Platform Tools. Start typing those commands. :)

    hi, i do what i read but when i flash rom to phone and starting phone after set up rom i had Encryption Unsuccessful - Reset Android
    error.
    Here are my shell codes. Sorry about my bad english :)
    Code: 
    ~ # ←[6numount /sdcard
umount /sdcard
~ # ←[6nfdisk /dev/block/mmcblk0
fdisk /dev/block/mmcblk0

The number of cylinders for this disk is set to 973824.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
   (e.g., DOS FDISK, OS/2 FDISK)

    I faced the same problem. Instead of umount/sdcard in step 3, try unmounting everything except sdcard in twrp. Then give it a try again. It will work I think :)

    Can anyone elaborate 'Step 7 - Create new data partition' , what should i write in cmd?

    (ADB SHELL/fdisk) n
    (First cylinder) -> you have to indicate the same start cylinder of partition 14 read in step 6 (What should I write here?)
    (Last cylinder) -> +8192M (this will create a 8gB partition)

    Thank you.

    After deleting the partitions 14 and 15. Creating a new partition. Write the start cylinder+1 of partition 13 as the start cylinder of the new partition. Then follow the process.

    step 11 ("wipe" data and sdcard to format your new partitions)is to do from twrp?
    during step 12((PC) adb push myrom.zip /sdcard/
    (PC) adb push gapps.zip /sdcard/) is there any need to assign the directory of rom in pc or just write the commands given in tutorial or i need to save the rom in c drive?

    If you want to use the commands to push as given in the tutorial, save the rom in the platform tools folder and assign them the same names. And yes wipe both in twrp. Hope this helps :)
