[Q] Flash directly from official CM11 to 4.4 OTA-based CM11 using bootstack?

I'm currently on the official CM11 nightlies, and I just haven't had the time to go through the entire process required to switch to the 4.4.2 OTA-based CM11 ROM. However, the random reboots and SODs are getting to me so much these days that I'm willing to try something different to quickly flash over to it. I was wondering if anyone knew if the following process would work:
Reboot into recovery
Make a backup of course
Flash TWRP 2.7 and reboot recovery
Flash the 24A OTA bootstack from XDABBEB's VS98024A ROM and reboot recovery
Wipe system, cache, dalvik
Flash JackpotClavin's OTA-based CM11 over my current install and reboot
I realize a dirty flash in this way may introduce its own set of problems, but I'm willing to take the chance if it means I can go straight from my current CM11 install to JPC's without having to wipe everything and go back to stock first.
I'm very comfortable with the command line and I have a good knowledge of how most Android devices work (bootloader, radio, recovery, kernel, cache, system, and data, and how they all tie together, all that necessary info). I just don't really know much about all the extra stuff for the G2 and I haven't had time to research it, so I've got no clue if flashing the bootstack is all I need, or if I'll also have to go hunting for a 4.4.2 radio zip to get the baseband up to date or anything else.

Follow steps 3-5 in XDABBEB's thread you posted and you should be good to install the CM11 4.4.2 based release. No harm in trying a dirty flash, worse case you need to wipe and install clean anyway.

Replying to say it worked perfectly, for anyone else in the same situation. I updated from the official CM11 4/26 nightly to JPC's 4/30 CM11 build by following the steps in my first post (and without wiping data or internal storage) and it booted right up with no issues whatsoever like a normal nightly upgrade. Huzzah!

I did this same thing although my previous CM 11 worked just fine except my GPS didnt work. So after this install and upgrading my bootstack and modem to 25A that my GPS would be fixed but its still broken under this as well. Any ideas guys?

Did you make sure to get a GPS lock on a stock based 25A ROM by opening maps and letting it locate you? That seems to calibrate the GPS sensors.

I found that I had to go to a stock-based 25A ROM to fix this as well. Not a big deal - first back up everything in TWRP, wipe everything except internal storage, flash xdabbeb's ROM, get the GPS lock, then reflash as above (not really necessary if you're restoring but I did it anyway), then restore from backup.
I'm now on a 25B bootstack (dirty flash) and so far, so good - it's much more stable than straight CM11.

[Q] I cant install CyanogenMod on my LG G2. Any more ways to install it?

I am unable to install Cyanogenmod. I have TWRP that was installed with AutoRec. I tried flashing the Stable 10.2 CM version,and when I flashed it said "Failed", which put me into a security error boot loop. Then I tried a nightly, and it said "Success" and when I tried to start it up, it put me into another boot loop. I have the stock Kernel, and I am rooted. Is something like goo manager or rom manager better to use for this? Or what is the safest way to install a custom ROM

JackpotClavin's version is the only one that works on the VS980. http://forum.xda-developers.com/showthread.php?t=2702958
Sent from my XDABBEB VS98025A v2.0.0 using XDA free mobile app

What he said, the official nighties only work with the JB baseband.

So is there any other way to do this? I saw that is is extremely risky, and it will permanently brick my phone. Is there any other thing im able to do to flash this?

If you want CM11 with the KK baseband(24A), use the version z3pp3lin pointed you to, otherwise most other AOSP based roms have already been upgraded to work with the KK baseband, use one of those. Just double check the notes on the rom to make sure it's KK/24A based.

Do I have to do all of those steps? You said there is a like for cyanogenmod for 24a. I don't see one though

All those steps are required to manually install a recovery on KK, that was pre-autorec, if you've already installed TWRP, you can skip to step 11.

You have the 24A KK baseband on your phone, you can only use roms that work with that baseband. If you specifically want CM11, you need to use the rom linked, otherwise any other 24A KK based rom will work. Check the notes for any rom you want to install to see what baseband it works with.

So If I want cm, I have to use his links correct? I just want to be sure so I don't get another bootloop

Why not just use a AOSP or CM based ROM that works with the 24A baseband... CM is good, but hardly the "best" ROM out there, if there is such a thing... Try AICP 6.0, it is extremely stable and the VS980 version is excellent and very feature packed.

Im about to flash the cm version and we will see how this goes

I downloaded the rom onto my phone but I'm scared for some reason. Is it guaranteed to not brick if I'm on the right version?

Not too freak you out more, but no, there is no guarantee. That's why every ROM has the disclaimer in the OP. By flashing you're taking responsibility that you understand the risks involved. If you flash cm and damage your phone somehow, it's on you. So it's either stay with rooted stock where you know nothing will happen, or flashing and taking the risk. Your choice...

Alright, but is there any way to know if a rom is successfully flashed other than it saying successful or restarting?

Can i install Cyanogenmod 10.1 after flashing cm12.1?

I wanted to try and see how cm10.1 felt so i am going to install it. However i would first like to know if there are going to be any issues. Will my device get bricked? Its the XT1058 with bootloader unlocked, its in 34.B7 i think is the version which is the one of lollipop i believe (I may be wrong). I am currently in cm11 and have installed cm12.1 before as well as a flashable backup of the official brazil release. However the brazil rom wasnt the "complete" one, it was pretty much like installing cyanogenmod, i didnt have to use the rsd lite i just flashed it through twrp because it was a backup. So... thanks in advanced everyone.

Dirty Flash CM 12.1 From Marshmallow Rom?

Hey, I just wanted to know if it would be possible to dirty flash CM 12.1 from my current rom which is Pure Nexus Project. Would there be any problems considering CM 12.1 is based on Lollipop? Or should I flash Lollipop first then proceed with 12.1. Also I have no interest in the unofficial releases for CM 13.

Don't dirty flash....

Yea... pretty sure a dirty flash downgrade will have no hope of working...

You could always backup and try, that way you would have a restore point for when it almost certainly turns out to not work going from a MM aosp ROM to a lp cm rom via dirty flash...

I'm sure you already spent more time on this issue than actually doing a clean install would have taken.
Nowadays a clean install means a factory reset in recovery with what you keep all your files and personal data. You make a Titanum backup before flashing, and after you let Google install all your software, you just restore the data to the applications.
You basicly can't retain any system data going from one rom to another, so those setting will have to be set by hand anyway.

Official CM13 is now out. And don't dirty flash, it probably wont even boot.

as many as are telling you not to dirty flash, i wont. but, i will tell you to make a nandroid backup in recovery first. that way when you do dirty flash, and things dont go well, you can always restore your backup.

question about installing a nightly update.

Hi i flashed a month ago aicp to my xperia sp and now i want to install a nightly of the same rom.Do i have to do full wipe or just flash the rom?I am using cyanogen recovery.I am asking this because in my previous rom i installed a nightly update without wiping and i ended up bricking the phone.

I read everywhere that the safest way is to do a full wipe, and since you have nothing to lose it won't hurt, so i think you should.

yes it is practically the correct way to update a nightly.
However do bear in mind that the nature of nightly is that it might have problems after different builds, therefore having a previous build zip handy would really help you. Also backups!
In case of a problem, clean flashing sometimes aren't really your go-to method to correct stuff. Always assume it as a last resort.. In case you faced any problem do kindly share here.

so i sould install the nighlty without wiping?

1. So you saying that a new update might/could be worst than the previous, correct ?
2. Do we need a full wipe of everything like first time (data, system, dalvid cache, etc) before install an update of the same rom (nightly 20151214) ?
3. Should i install it via recovery or ota ?

Yes, nightly is a daily release where changes are huge in the back end.. Sometimes a simple change can make a build unbootable. Sometimes it introduces new bugs. Sometimes it is better and fixes everything. It is of course a good thing to update to the latest if possible, it is just that it is also vital to know what we're going to face when we flash a new update. So that we can make backups beforehand in case something really bad happens.
If you are installing an update to the same ROM there is no need to wipe anything. Wiping is optional.
↑ Note, if you are reverting to a previous build, you will need to wipe everything as there will be conflicts for the system data. This is why frequent/periodic app backups useful.
You can do either both of them without any problem

Thank you very much.
It's the first time i flashed a custom rom (the AICP 10 successfully :cyclops: ) and i got overwhelmed with all these endless customization options .
