Hey, I was wondering if it'd be possible to downgrade from stock 5.1 back to stock 5.0.1 by running the flash command in the factory nexus 5 image (for android 5.0.1), also downgrading the bootloader and radio in the process?
I'm not sure about this device, but I recently hard bricked my moto g downgrading from the android 5 bootloader to the android 4.4 bootloader, so I was hesitant to just run the downgrade process.
Thanks.

Yes, it's a nexus device. You can flash whatever factory image version you want on it.

Can I just follow this instructions to downgrade from 5.1 to 5.0.1? Or should I do something else? I'll lose root, right? 5.1 messed up my Nexus 5, battery is lasting 40% less than it used to, and Google Play Services seems to be to blame. Getting real sick of this.
Yes.

Yes, follow the instructions. And, yes, you'll lose root. And, no, you don't need to do anything else. Except maybe root it again you want that. Also see this, http://forum.xda-developers.com/showthread.php?p=47156064

Anytime you flash any factory images you're device will be wiped clean. Data, app, everything. So back up anything important.

Is there any way to get my user data back, so app settings ans so on? If i just restore the data partition from the backup i made on 5.1 with TWRP i get a botloop. It makes sense that i can't just use my user data from a higher version but how do i fix this?

You have to flash 5.1 again. Restore data from TWRP. Boot the phone and use some backup program (titanium backup is my favourite). Flash 5.0.1 again (do not restore backup from TWRP), boot and restore from the app you choose. You will probably get some force closes, but you can then just wipe data for those FC apps.
Quick suggestion: if it is possible, make .xml backups for system data.

Hey guys, I've read a lot on updating after being rooted, but just need to confirm before I do mess up anything.
All I have done is Rooted Stock (I have TWRP on the phone), and have flashed volume mod, and also battery percent mod. (Other then that I am running Nova Launcher, Titanium Backup)
Guessing I need to flash the back to stock for volume and battery percent (Correct if I am wrong).
And then how exactly do I go about updating to 4.4.2 and preferably retaining root?
Sorry I know noob question, just making sure as I've always unrooted, and never had any mods when I have done updates in the past.
1) you have to flash back to stock system image since you modded your phone
2) once you either get the OTA or sideload it, you just flash cwm/twrp in fastboot and then flash the supersu.zip
thats all
so in other words go back and unroot completely, go completely back to stock, and redo everything from the beginning?
Just flash the 4.4.2 stock rooted rom in the dev section

Or you can flash the Updated Super SU zip right?

You are flashing back the stock ROM. If you want to keep data intact, flash only the boot.img, system.img

that won't help you get back to stock.
I guess I need a tutorial on what you guys are talking about because I still am not understanding..
Would flashing the rooted 4.4.2 work? And if so what do I need to do before I flash this?
How exactly do I go about only flashing only the boot.img and system.img?
Will I loose anything through this process?

One safe way to get the OTA, taking into account that you modded your phone, is:
i) flash system.img then flash stock recovery,
ii) once the OTA update is on your phone and you have accepted it (it installed itself) you are back to stock.
iii)flash your custom recovery and re-install your SuperSu to get back your root.
Good luck
Due to bugs that started from 4.4.3, i will be downgrading from 4.4.4 to 4.4.2
I'm running stock rom (4.4.4) with xposed + gravity box.
Each time when upgrading from 4.4 to 4.4.1 to 4.4.2 etc I would simply flash the system.img from the downloaded factory image, then reinstall xposed and root, hence not needing to wipe userdata.
Would it be ok to do this in reverse? Ie flash the system.img of 4.4.2 without wiping anything? Cheers!
Yeah it'll be fine

did you wipe data to ensure your bugs aren't just incompatible data from an older version?

I haven't but many other users are having the same issues with 4.4.3
There shouldn't be incompatible data anyway as i'm upgrading from stock rom to stock rom. Flashing the system and boot images through fastboot would give the same result as updating via the OTA updates as far as i understand

Yes you're right it would. I always recommend a wipe after an OTA too. Your OTA doesn't know if the apps you have are compatible or not.
What's the bug out of interest?

Hi Experts,
I've Nexus 5 running stock ROM LRX22C with CWM. I'm trying to flash stock 5.1 but I get the error in the start where it says my device has fingerprint user keys from kitkat 4.4 instead of 5.0. The exact message is as follows:
This device has Google/hammerhead/hammerhead:4.4/KRT16M/893903:user/release-keys
Status 7
I can edit the updater script to avoid checking it but I would like to fix it. Please advise if I need to go back to stock 4.4 and then upgrade to 5.0 and then 5.1?
Is there any lesser tedious method to fix it?
Thanks in advance for your help.

Download factory images and flash system.img, boot.img, radio.img and bootloader.img using fastboot while booted into the bootloader.
Just so that I can understand better, do I need to flash for all versions of just 5.1?

What do you mean?
If you mean flash old factory images first, then no, there is no point. Just download the 5.1 factory images and flash the .img files I mentioned (don't flash userdata.img since it'll wipe all data).
Thanks. I'll follow the instructions.

You can't take an OTA with a custom recovery, that's the problem.
Also, it's time to get rid of CWM.
So, what's your suggestion?

If you don't factory reset, you will bootloop.
I'd recommend you use fastboot to flash back to kk. Any time you change android versions you should wipe your device which means to get it to work you will lose your apps and data.

1) Yes, see below.
2) You could to flash the exact recovery image of the build you are running now (which should be LMY48M), but save this step for last.
3) If I'm thinking correctly, unrooting will also restore some system files back, and IIRC, some of these might be install-recovery.sh and recovery-from-boot.p. What these will do is to restore stock recovery if, on a reboot, it catches something else on the recovery partition. Going by this perspective, you wouldn't even need to manually flash stock recovery.
4) You don't need to relock the bootloader to successfully install an OTA.
Don't rush this, take your time.
