CM12 to CM11 - ONE Q&A, Help & Troubleshooting

So I was trying to get back to CM11 from CM12 via fastboot commands. Everything went fine until the "fastboot flash system system.img" command. It gave me an error (screenshot in the attachment). Now I'm stuck with TWRP recovery and fastboot. Can't boot in system. When I reboot the device, it boots and goes into TWRP recovery. I have CM12 backup in my device and on the PC. Can I flash that? Please help guys.

How did you install adb/fastboot? That error usually occurs because of an outdated adb/fastboot version. It's probably safe to restore your backup.

I didn't get the "how did you install adb/fastboot".
I downloaded the latest SDK bro. It's v24.3.3. I even tried the slim SDK. It would be very kind of you if you give me the link to the SDK that would work.

Download to your PC, connect your phone while in TWRP and copy it across.

Go into the Mount menu in TWRP and make sure MTP is enabled.

Did you wipe first? You'd need to perform a full wipe before flashing the zip. To do this you go to the Wipe menu in TWRP, then select Advanced Wipe, select system, data, cache, and dalvik cache, and then swipe to wipe.
Is there any reason you chose such an old build?

Back to CM11.
44S and 38R were unofficial so I didn't want to take any chances.
Thanks a lot for all the help bro. You're the best.

Cant Flash Anything in Twrp

i cant flash anything in twrp everything i try to flash says failed. other than that twrp works fine. any ideas why?
Sent from my Nexus 5 using XDA Premium 4 mobile app
Usually might have to reboot recovery in TWRP before flashing. Normally with Catalyst that is what it requires me to do and all works fine.

TWRP is not working, and i dont have a rom because of that

i've installed TWRP recovery and nothing is working, the data wiping is not working, i cant install any new rom, so right now im stuck with not working recovery mod, and i cant boot into android.

[Solved] Flash OTA zip?

I've applied previous OTA zips by just flashing in TWRP. However I'm getting an error this time around. I'm on the KK build ending in P, but when i try to flash Lollipop it says my build fingerprint is incorrect, that it's the KK build ending in H. Anyone have insight on why this is?
Sent from my Nexus 5 using XDA Free mobile app
As it says, you're not 100% stock so it won't flash
This would be due to my recovery and xposed i take it? Or strictly xposed?
Sent from my Nexus 5 using XDA Free mobile app
Definitely Xposed, probably recovery as well
Xposed. You'll not just need to uninstall the xposed files, but the app too as ART doesn't like to boot with that app installed.
Recovery is fine. Only issue would be that an OTA.wouldnt automatically install. You'd have to manually boot into recovery to flash.

Do i need to sideload the ota zip in recovery or flash like normal?
Sent from my Nexus 5 using XDA Free mobile app
You may want to look at flashing a full ROM.zip instead as it will be much easier.

I can just fastboot flash the images separately... Which ones do i omit to keep recovery and user data?
Sent from my Nexus 5 using XDA Free mobile app
Don't flash userdata.img and your storage data will be fine. If you want to keep your custom recovery, don't flash recovery.img.

Funnily enough, recovery.img and userdata.img haha
Also you'll need to delete:
/system/recovery.init.boot.p
/system/bin/install-recovery.sh
Before boot, although flashing superSU should prevent them installing stock recovery

You listed two files i need to delete. Is that before or after flashing the img files?
I've never had a problem before, i don't get why it's failing now... Keeps saying I'm showing an old build fingerprint. Never seen this error before.
Short of being rooted, I've removed any modifications to my system. Really don't feel like wiping the whole device.

Bootloop

I was trying to get back to CM11 from CM12.1.1. I flashed CM11 33R; the flash was successful but it won't boot into system and was giving some process error. I tried to wipe the dalvik cache but no relieve. So I restored the CM12 backup and it was successful too but the OnePlus One went into bootloop. Please help genius minds!
Running Android 5.1.1
BTW, I forgot to mention, I did it via TWRP recovery and not fastboot.

Yes I did a full wipe. Wiped dalvik,data, cache and system. I've downgraded to CM11 before too but this never happened.
My guess would be that the needed firmware and baseband for cm11 were not flashed correctly.
What is your TWRP version?

The TWRP version is 3.0 0-0
The best idea would be to wipe fully (system, data, cache, dalvik cache) with TWRP, then flash the stock images for CM11S.
