TWRP 2.8.6.0 won't flash latest cm12.1 nightly - ONE Q&A, Help & Troubleshooting

I'm trying to flash the latest /bacon nightly zip file on top of the stable cm12.1 with TWRP 2.8.6.0 and I'm getting an error that said cannot install this and advice me to do a factory reset instead. What do I do wrong?

What exactly are you trying to flash over the top of? When you say stable do you mean the stock ROM (Cyanogen OS 12.1)? If so, you can't do that, they're different ROMs. When going from the stock ROM to a nightly (or vice versa) you need to wipe properly (system, data, cache, dalvik cache) first.

[Q] Updating Team EOS ICS 4.0.3 NIGHTLIES

Hi !
I have installed on my xoom wifi MZ604 Team EOS ICS ROM.
How to update the ROM?
I mean: How to update the nightly build?
My is Eos-wingray-47 build and i want to update to 48.
I need to flash it as a normal ROM?
And what about the G-APPS? Just flashing it?
no need to wipe? thanks
Wipe the cache and Dalvik Cache. Flash the new nightly build and then flas the Gapps. Do not reboot between flashing the nightly and Gapps.
That's how I have done it for every build since they got the camera working and not had a problem.
So I have to wipe?
No you don't need to wipe data, just the cache and Dalvik Cache (it's recommended that you do this to make sure old cache information won't cause issue with updated info).
OK...
And when flashing the G-APPS i dont need to wipe,right?
just cache?

No need to wipe anything when updating Gapps if you flash Gapps immediately after you flash the Eos Nightly.
It depends if you are changing versions of Gapps. If you are just reflashing Gapps after flashing each nightly then no. If you are flashing a different version of Gapps it depends. You need to look at the release notes for that version. If you were running version 9.x and upgrading to a 10.x version a full wipe was needed. Incremental 10.x upgrades, say from 10.1 to 10.2, did not need a full wipe.
The biggest thing that I have seen cause problems is that people are rebooting between flashing the nightly and Gapps. This is what I recommend.
-reboot into recovery
-perform a backup
-wipe the caches
-flash the new nightly
-flash Gapps
-reboot
I always perform the backup. Yes it takes some time, but when something goes wrong you always have the ability to revert back to a good working state. Well worth the few minutes it takes to have that peace of mind.

i can only answer this surely if you tell us which rom/ version you currently using .... but if you allready on CM12.1 update this way:
(dirty install):
backup current rom (in case of problems)
in recovery install the new update
wipe cache + dalvic-cache
now, if you get any issues or FC's etc... you will need a clean install (fatcory reset / data wipe)
remeber this rom is still under development so sometimes a clean install in fact is needed...

[Q] Before flashing a 5.1 rom over a stock 5.0.2 rooted do i need a cm12.1 nightly ?

I was on CM12 stock 5.0.2 (version 12.0-YNG1TAS2I3) and i wanted to root my phone , so I unlocked bootloader and rooted the phone but now I want to flash a new Rom but I ve read in a couple of rom threads that we have to flash another 5.1nightly before flashing a ROM and I am not sure I understand this part.
I would be grateful if someone could help me with the process of flashing a 5.1 rom and gaaps for the first time on a freshly rooted phone
P.S : ( I also want to use calaukin's gaaps modified by mohit (http://forum.xda-developers.com/oneplus-one/themes-apps/gapps-modified-slim-gapps-calkulin-t3082242).
Flashing the CM12.1 nightly first ensures that your firmware is up to date. The process goes like this:
1. Download the latest CM12.1 nightly and install it with your custom recovery (no need to flash gapps, but make sure you perform a full wipe (system, data, cache, dalvik cache) first).
2. Boot the phone up once.
3. Boot back into your custom recovery and perform a full wipe.
4. Install your chosen ROM + gapps.
5. Boot phone.
6. Enjoy.

Thank you so much . I followed your guide too so thank you for the support .
It is not necessary to flash nightly first, most ROM threads provide a separate firmware flashable .zip (just make sure it is flashed correctly, cause people reported issues with newer TWRP than 2.8.6.0)

I used to share your opinion. But, while a lot of ROM threads do provide a firmware zip, they aren't maintained, it's usually uploaded and forgotten about. Flashing the nightly ensures that you're on the very latest firmware available.

Cannot wipe cache

Hi,
I have a little problem with the official TWRP on my HonorView10 (eu) (C432), I cannot wipe the cache (dalvik is ok).
I've flashed the stock firmware just in case but still, TWRP is saying the same thing :
Unable to wipe Cache.
Unable to wipe /cache.
Any solution ?
Use stock recovery - there is no TWRP version that works 100% on the BKL-09
Thanks for your answer, but then, how do I install a custom rom then ?
I'm getting into a bootloop every time I try to install a rom (no matter the rom).

Via adb of course.
Check openkirin.net for guides and a few great roms that work on our EU View 10
