need advice with flashing rom - ONE Q&A, Help & Troubleshooting

Hey, so I installed newest oxygenOS 2.1.4 for oneplus one which cames with its own recovery...I want to go back to cm12.1, don't have backup so I want clean and fresh installation. Now I am not sure what is the best method to do it without problems or bricking my phone, alot of people are bricking their phones when reverting back to cm12.1.
I want to know few things and can't find it on web, can I flash TWRP recovery without problems? Saw posts where people get into bootloops when doing this. Should I download fastboot zips and install it via adb or flashable zips and install it with recovery. If I choose flashable zip than I need to download kernel and modem also right? Or if I choose fastboot zips and don't install TWRP, would there be any problems because right now I see oneplus logo when I am in fastboot so I assume its their version and people said its buggy and flashing ROM with it is like playing russian roulette.
This is so confusing to me and I can't find those answers in flashing guides.

I used this guide http://forum.xda-developers.com/oneplus-one/general/guide-return-opo-to-100-stock-t2826541 to go back to 12.1 than installed custom ROM

[Q] Having problems with recovery (LS980)

So I finally decided I wanted to flash custom roms on my new phone (Sprint LG G2). I did some research on the pros and cons and the risks and thought I was smart enough with tech that I could figure it out. I was able to root no problem, it was really easy to just follow the top root thread step by step. Now I'm trying to install a recovery method to backup my stock rom and flash new roms and I'm finding it really difficult. I'm following this guide http://forum.xda-developers.com/showthread.php?t=2522965
I chose this one because it is up towards the top of the forum. I installed flashify and set the recovery image to the latest version of twrp (2.6.3.3) like OP suggested. I then backed up the stock recovery and the restore kernel in flashify. I rebooted recovery and there is an error. I read through the post and someone suggested using the previous twrp recovery image (2.6.3.2). Now it works, I immediately backed up the stock rom (with root). Now I'm worried about flashing a ROM when it says to use the most up to date twrp (which I don't have and I'm not sure how to update it now). Also I'm incredibly frustrated because I've reached my flash limit in Flashify because I was switching between different versions of twrp. I'm also worn out reading through posts to figure out how to get my recovery working and up to date. It's taken me like 3 hours now to get where I am. Can I install custom ROMs on an out dated version of twrp? Are there additional risks? Any information or resources on the recovery would be much appreciated.

I'm trying to avoid another brick PLEASE HELP

Howdy y'all. I bricked my old G2 D800, I don't want a repeat with the new one. I tried doing all the research I could. I have a new D800, 10d, 4.4.2. I want CM11, tried reading the threads on that and custom recovery. I just need a little help to make sure I have the order of operations down pat before I crash another. I've rooted and flashed ROMs before, but not with th locked boot loader and security AT&T has.
Please just correct me if I'm wrong. Through the threads I have read I believe this is what I am to do.
1.) Flash my 4.4.2 back to 4.2.2 using LG FT
2.) Root using IO23
3.) Download Flashify & install TWRP 2.7.7 with Loki
4.) Follow steps to install CM 10.2
5.) Follow steps to install CM 11
Of course make backup once 4.2.2 plus root and TWRP is achieved before trying CM. I just want CM like I've had on previous phones. Thanks in advance.
All is good back to being ROM junkie. Anyone who does read and wishes to flash custom roms and get custom recovery on KK. Obtain root via IOroot25, then use AutoRec Recovery Installer for TWRP recovery.

[Q] How to backup stock recovery?

Hi,
I want to root my Mate7 but I am not comfortable with messing with recovery. What is the way to backup stock recovery so I can put it back with fastboot flash recovery after rooting is done?
Thanks.
Hi xtonda - the package going around for unlocking/rooting the Mate7 currently that contains the recovery_b60.img also contains a copy of the stock recovery.
If you follow any of the guides available (off hand I can remember http://mate7.net/ascend-mate7-bootloader-unlock/ from the other day, but plenty guides available on XDA and elsewhere) the tools/driver package includes the stock recovery.
Flashing the stock is done in exactly the same way as flashing the CWM, just with the different file.
So you'd unlock, flash CWM, root the device, then flash the stock recovery again
Cheers - hope that helps!
Hi, I found two guides to root Mate7 here and each has own package with CWM recovery and some original recovery. However these original recoveries are not the same so I am not convinced that they are exactly the same as the one in my device (obviously at least one of them is not) since there are several Mate7 variants and ROM version and is unknown where these "original" recovery images come from. That is why I want to download original recovery from my device and flash it back after rooting.
Or to boot CWM recovery only temporarily without flashing it, I found that it should be possible using "fastboot boot" command. Is that possible?

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.
