[One (M7) Original Android Development] nkk71:
yep, both KK and LP ROMs are running fine.

Ok so here goes, exactly what I've done step by step, hope this helps (note: I had completely wiped everything from my phone due to RUUing & formatting it, so nothing was there)

update firmware to 7.15.401.1

http://pastebin.com/HiA36mBZ

installed ViperOne 7.0.2 using regular TWRP (no particular reason I chose that ROM, just happened to be in the right folder)

installed ElementalX 18.0 using regular TWRP

(I could have used MultiROM TWRP, but used the regular one cause I had it there already)

time to MultiROM:

flash recovery: TWRP_multirom_m7_20141028

Install MultiROM:

inside TWRP MultiROM: 1st install multirom-20141005-v28b-UNOFFICIAL-m7

then install multirom-20141028-v29-UNOFFICIAL-m7

Install DirtyUnicorns 9:

Now since the ROM I was installing as secondary (Dirty Unicorns 9) has "block_image_update" in the installer-script, it won't flash to secondary, so instead, I first moved my primary (ViperOne) out of there:

MultiROM -> Swap ROMs -> Move primary to secondary (obviously I also changed the name when moving it)

so now I have no primary (only ElementalX kernel), I made a backup of that and called it "Base 0" (which i can restore any-time to get MultiROM to boot up)

then installed DU 9 to Primary (do not inject MultiROM) -> Move to Secondary -> restore "Base0" to Primary -> bootup and it works :D

ViperOne is also still as a secondary and also boots fine.

and as primary, nothing, just the "Base 0" backup of ElementalX 18.0

here are all the ROMs, I've tested all successfully; installation method is the number in brackets

Secondaries: HTC Sense 6 ROMs

(1)**KK** ARHD Sense 82.0

(1)**KK** ViperOne 7.0.2

(1)**LP** ARHD Sense 90.1

(1)**LP** MaximusHD 50.0

(3)**LP** InsertCoin 6.0.3

(1)**LP** Google-Plus-Edition-LP_m7_v2.00_020315

(1)**LP** SkyDragon+GPE501+M7+V6.0.0

Secondaries: AOSP based ROMs

(1)**KK** SlimKat 9.0 (including gapps)

(2)**LP** LiquidSmooth 4.0 (including gapps)

(2)**LP** Dirty Unicorns 9.0 (including gapps)

Secondaries: Other ROMs

(1)**** MIUI (miui_One_4.8.8_5cf931dfdb_4.2)

Installation methods:

(1) -> directly to Secondary -> works fine

(2) installer-script contains "block_image_update" so flash to Primary (do not inject MultiROM) -> Move to Secondary -> restore "Base0" to Primary -> works fine

(3) -> directly to secondary -> boots -> Android is upgrading -> then it reboots and gets stuck :(

but since it got to Android is upgrading (but not showing any adb logcat activity during bootup), I figured maybe something with the kernel is weird-ish, so I just flashed "ElementalX-m7-19.2-Sense" into the secondary partition -> works fine :)

(it could have been something else, but I didnt bother testing further :rolleyes:)

EDIT: I believe the problem was due to the "restorecon -FR /data/media" as described on page 61

you should flash the Fix File Contexts zip from post 610

Hints and Debugging Procedures:

do not reboot using the installer, go back to BACKUP and check the primary partitions are unaffected (click Refresh Sizes, to update)

make sure the ROM installed properly by going to MultiROM -> List ROMs -> (select the ROM) -> Backup -> Refresh Sizes then make sure the partition sizes make sense (eg if you see a zero size /system partition, it's not going to boot)

run a "adb logcat" when you see the ROMs bootanimation, it will start with --waiting for device--, then after a few minutes begin dumping the log, remember some of these ROMs take quite a long time to boot up, easily approaching 20mins (maybe even longer)

(Note: in some ROMs the adb logcat option could disabled/not authorized, so dont rely on it 100%)

on one or two occasions had to go back to recovery -> MultiROM -> List ROMs -> (select the ROM) -> Wipe /cache and dalvik

If you want me to test any particular ROM, let me know, but so far all of them have worked for me :victory: :highfive:

EDIT: right now I have all 12 of the above ROMs installed as secondaries, no primary, and they all boot fine

but i only have 3.5GB of storage left :P
