[Q] Few questions about 5.0 flashable zips

I'm running latest L preview (rooted, custom kernel), multiROM.
1. I flashed LRX21O flashable (NOT this one , can't find that one ) as a secondary ROM . It booted up properly etc but it didn't give me any option to restore my previous apps. I tried doing factory reset, reflashed. It didn't help. Is there any way to force it?
2. How do I upgrade my recovery from android L without using pc? (flashify doesn't work on L so I can't flash .img files without PC)?
3. Is it neccesary to flash new radios?
3.1. How do I flash radios if I want to keep my multiROM and L preview as my primary ROM until I move everything to 5.0 final (I am planning to have both ROMs on my phone for a few days until everything is really configured because I don't like it when I find something missing on my new ROM that I just had on a ROM that I just deleted)?
(I have quite fast internet so it is not a problem to download these flashable zips)
Thank you for your time

[Q] Sideload another ROM

Hey guys, I'm kinda new to the Forum and figured I'll just post my question here.
I'm running a nightly of AICP 7.0 on my Nexus 5. I previously ran Lollipop but discovered that it drained a lot more battery than KK so I switched back. Now I want to try the Cataclysm Lollipop ROM, but I don't want to install all my apps again or wipe my current ROM. Is it possible to just sideload the Cataclysm ROM over my existing AICP ROM via TWRP Sideload function? If not, you guys have any clue how to do this? The main reason I want to sideload and/or install without losing my apps is because I want the Google Cards and Google Now to work for me which it doesn't in Lollipop. I previously ran KK and sideloaded the Lollipop image and that left me with all my apps and Google Now as it is and everything was good (expect for the battery drain and camera FC on Lollipop)
Any help on this would be much appreciated

sideloading in twrp means to put the file on your phone via adb. what you want to do is dirty flash. first, make a nandroid backup in your recovery(in case dirty flashing doesnt go well, then you can restore your old rom). then download and flash the other rom in your recovery(su and gapps also). by dirty flashing, you dont lose data. if your dirty flash didnt go well, you can restore your nandroid backup.

How do I clean install a lollipop ROM?

Hey,
I been trying different custom lollipop roms on my G3 but for some reason after I go into twrp and do a factor reset then install a different lollipop ROM it will start up with the screen saying android is updating like you if you would flash and update. I alos even tried doing format or delete everything option I twrp, and put a rom on my SD card and it did the same thing. Is there something I'm doing wrong or is that just normal?
Thanks

nandroids, firmware & multiROM - Reqst clarification please!

Multi part question here which, in my mind, are somewhat related.. I've read up on many posts but these questions I still am not totally clear on and would rather not risk bricking trying to experiment....
#1) When a nandroid is taken on a particular firmware (say 4.4.4) and then after upgrading firmware to a different firmware (say 5.0.2) and I encounter a problem where there is no OS left after wiping and failing to install a custom ROM (TWRP will report: no OS installed! are you sure you want to reboot?), can I flash restore the 4.4.4 nandroid and be ok or will I brick because of bootloader incompatibility [I come from motorola phones recently - this is my first HTC]?
#2) When adding additional ROMs to multiROM do the ROMs have to be of the same firmware version? Moreover, can multiROM have a sense ROM as it's primary ROM and a GPE ROM as a secondary ROM and vice versa?
( FYI - as of this posting I still have yet to successfully boot my secondary ROM using multiROM - I can successfully install mod'd TWRP, the manager, and the patched kernel but something is eluding me - anyone with a link to a very simplified and step by step procedure on installing mulitRoom would be appreciated. I thought I had enough understanding [of the procedures I could find anyways] but apparently not, as I obviously can not get secondary Rom to boot.) I'm able to add the ROM in TWRP but when I reboot, the ROM is not listed after pressing cancel and going to the multiROM boot screen, there is simply nothing there.
#3) Re: multirom - When I reboot into the mod'd TWRP recovery and flash gapps (or any zip file for that matter) how do I know which ROM the zip is being applied to (ie: primary or secondary)?
Feel free to answer as many or as few of the questions as I know it is a lot. Thanks in advance!

You won't brick it.. softbrick/bootloop maybe.. but it's easy enough just to keep a copy of the different firmware zips to flash before restoring that version nandroid.

Much oblige! I assume then what to do would be to NOT reboot to system but to BOOTLOADER and fastboot flash the zip? or would I flash the firmware from TWRP (I thought firmware had to be fastbootRUU flashed)?
thx again

Unable to flash any ROM on 6045

Hey there.
So, my 6045 was on that awful MM update filled with ads, so I changed the firmware to the Panasonic one in order to be able to install TWRP and next flash either Lineage or RR.
I have no problem installing TWRP using the Idol 3 suite (Here), however, whenever I try to flash the Lineage zip, or the RR zip, it gets stuck on the Powered by Android screen.
I always wipe everything before flashing the zips.
I have tried wiping cache/dalvik after flashing them, and also not wiping. Either way, and with both roms, the phone gets stuck, and I need to use the Panasonic tool again to restore the phone to a functioning state.
Please help, I've been repeating this process about 10 times, and it's getting very frustrating.
Thanks.
EDIT: Is the version of TWRP somehow relevant for this? The latest version I can install is 3.0, from the link provided. If I try to install this one I get a bootloop. Please help.

Hi, u need to flash the MM partitons zip first then the rom . Look on AlekDev customs roms threads, he usualy has the MM partition file.
