NINO-BOOT VIDEO IN POST 2

​

First things first

S-off and Root required

"At the moment" Aroma scripted Roms and Kernels are not yet compatible on slot 2+, unless restoring from a Nand backup, which is pre configured​

:victory: Good luck, and enjoy :victory:

STEPS ON HOW TO DO IT​

1. ensure your happy with the current state of your main/daily rom

2. NAND - back it up

3. download, install and configure either the free boot manager lite app or the pro version

4. NAND - back it up (not necessary, but advised)

5. download your scondary rom zip

6. open your downloaded bootloader app and slide accross to slot 1

7. install your chosen rom (do not wipe anything on first install)

DO NOT BOOT SECONDARY ROM

8. NAND - back it up, again (if your low on sd space, delete your earliest nand, and then next etc etc)

9. open boot manager when booted, and slide to slot 1, and boot rom

10. "Ta da". your now dual booting,

11, repeat these steps for further slots for tri/quad/etc booting

Tips

​

DO NOT RUN V6 SUPERCHARGER OR SIMILAR SCRIPTS ON ANY ROM OTHER THAN PHONE ROM, YOU WILL GET STUCK IN A BOOT LOOP

DO NOT SET UP PHONE ROM WHILE BOOTED TO A SLOT ROM

revert hboot

(read below and follow my guide)

HBOOT

​

​

after a major error recently I' found that for some reason I was struggling to even dual/tri/quad boot, after reverting to stock ics and updating my hboot to 1.49.0053 , I managed to find a patch to revert my hboot back to its original 1.49.0007 , il attach below, I recommend everyone flash this GO USE THE GUIDE HERE , all you do is place on root of your sd card (GSM USERS ONLY AS FAR IS I'M AWARE (CDMA TESTING APPRECIATED)), Then boot into bootloader and select yes when it reads the PG86IMG, I found after going back to this hboot , bootmanager was then able to edit boot.IMG correctly again

(added ALL CID'S to the pg86img.zip android text folder)

WILL WORK FOR EVERYONE

AROMA ROMS / KERNELS

​

​

Some people are having issues with certain roms/aroma scripted roms, the best way around it is to set up all roms on phone Rom slot (main) then back up, restore your original Rom to main, boot it, then in boot manager . Restore nands of other set up roms to other slots

SWITCHING ROMS​

Ensure all roms you want to boot into and out of, are Gapps (google apps) installed, ensure you have set up phone in bootmanager while booted to your phone Rom, and that you have opened boot manager in your slot rom(s) at least once so bootmanager app can download files needed and to write folders to sd

BOOT IMG​

If you find that your bootmanager can't create boot.IMG (not edit), navigate to the bootmanager folder on your sd, find the boot.img file in the slot your trying to install on, delete it, then restart bootmanager , and it should create it without problems,

IF NOT,

Try putting boot.img in the rom1/rom2/whateverslot you are using n the bootmanager folder on the sd card, then try just installing a different kernel to overwrite it, so it fixes it. thanks to meangrenie or making this common knowledge

if you ever run into problems, pull the battery, boot to hboot, select recovery, and flash the update.zip inside the phoneRom directory. It writes your backed up boot image. thanks too $MyName for making this common knowledge

BUGS​

​

(currently)

When booted to a jellybean Rom there is a charging/battery reading issue and in some cases data drop/connection problems
