Initial Setup
1) Have you flashed the dual-boot (aka DB ) kernel yet? If yes, go to step 3
2) Flash the DB kernel: Go to the DB OP here and flash the version for your model type -
xda-developers N7100 is for non-LTE models and t0lte is LTE enabled (AT&T, Verizon, etc). The zip will NOT list recovery in the name...
3) Have you flashed the DB recovery? If yes, go to step 5
4) Flash the DB Recovery: Navigate to DB OP listed above and flash the version for your model type (as in step 2 above)
5) Have you created the secondary system partition? If yes, go to step 7
6) Create the secondary partition image: Boot into the DB recovery and select Dual Boot Menu > enable mounting secondary and then select create secondary system image (also under Dual Boot Menu". This will take a couple of minutes. This only has to be done once.
7) Ready to flash primary or secondary ROMs: Note: It is probably a good idea to get in the habit of always selecting the FS (primary or secondary) that you want to affect just to ensure you don't wipe the wrong one, etc. Select Dual boot menu > enable mounting of (pri or sec.)... It stays selected until you boot into recovery and change it. You will see recovery flash (reload) with the appropriate FS selected. Obviously, don't select it again - logic loop... :P
8 ) You at least need to follow standard ROM installation instructions at this point such as wipe data, etc (as appropriate). Wipe Data/Factory Reset will leave the ROM (typical) and the 2nd option (wipe data-cache-system-preload) will wipe out the ROM completely so you can start "clean". Only the selected FS is modified so the other ROM is not affected. All apps and data are separate for each ROM. SD card storage is common so keep that in mind for an app that exists in both ROMs.
9) Installing to the primary partition does not need any special instructions. You should have already selected "enable primary". Select "Install zip" > Choose zip from sdcard or external > ROM to Primary FS. The difference between the "ROM" and "Zip" selections is that zips do not typically explicitly access the file systems - they use references in recovery.fstab which DerTeufel modified to point to the appropriate locations depending on your selection (primary or secondary). Yes, choosing install zip might work for installing a ROM to primary but NOT to secondary. Also, the intention is to avoid confusion.
10) Installing to the secondary partition MIGHT be more problematic since the zip has to be modified first to replace FS references with the secondary locations. When you select this option, it can take a couple of minutes since it is changing the references and then re-zipping to a modified file on the SD card. Note: The original will be gone (at least if it was originally on the SD rather than the external SD) so make a copy, etc before proceeding if you want it to be available for standard/primary flashing in the future. The modified file will always install to the secondary partition after being modified. Note: Complicated install scripts (such as AROMA) will likely fail. If you want an AROMA based installation then the safest way is to install it to the primary partition, ensure it is working, make a backup and then restore the backup to the secondary partition (using the DB recovery of course). Backup/restore will be detailed below.
11) Recovery does not automatically mount /system, and /data so ensure /cache and these are already mounted before running a zip that will need to modify them
12) Avoiding MTP issues: After flashing a ROM, recovery prompts you to install the DB kernel again. Otherwise, the kernel installed with your ROM will not be able to boot the secondary ROM. However, if you do flash the DB kernel right away (for now at least) you may have a problem with MTP (access from a PC over USB ). If you boot the new ROM (with the ROM's kernel which will work for PRIMARY) then MTP should be working. You can then flash the DB kernel after rebooting to recovery and MTP will still work (afaik). Similar to the AROMA note above, you might want to install a ROM to primary first even if you want it in the secondary partition. The install script will not need to be modified and a normal kernel will boot the ROM so MTP will work. Then you can flash the DB kernel, make a backup and restore to the secondary. Hopefully, this is only temporary but at least this workaround exists.
13) Ready to flash zips to primary or secondary ROMs Flashing gapps, etc. simply requires that the correct FS is enabled, /system and /data (as necessary) are mounted and select your target under "Install zip" > "Choose zip from..." > Zip to (primary or secondary).
