Hi,
Does anybody know how to downgade nexus 5 from lollipop 5.1 to 5.0.1?
Is it just flashing factory image or is there more to that.

Use Nexus root toolkit, just flashing factory image!

Downgrade from 5.0 to 4.4.4

So I'm ready to upgrade to Lollipop 5.0 but in case my root apps doesn't work I will downgrade to 4.4.4. My question is if it is possible to downgrade to 4.4.4 using normal method?
Thanks
Factory image or ROM.zip, yea

[Q]How do I retry Lollipop OTA flashing procedure? I'm stuck!

Here's the scenario:
I converted Moto G XT1033 4.4.4 to GPE 4.4.2
Then upgraded to GPE 4.4.4 and GPE 5.0.1, both by OTA
GPE 5.0.1 OTA ended up in softbrick
So now I cannot repeat the process beacause of the new bootloader, GPE 5.0.1 OTA brought with itself. And that bootloader would cause a hardbrick if I tried GPE 4.4.4 OTA on the device now
Questions: (No question is related to the other)
Would I be able to install Stock Lollipop OTA when I get one on 'Stock rom'? (I can revert to Stock 4.4.4) Would Stock Lollipop OTA mess up with the current bootloader, GPE Lollipop OTA has installed?
Is there any way I could flash Lollipop Stock image later, when it's available?
What can I do to set things right with the 'bootloader messup' that's caused right now?
Thanks, in advance!

You are another who has made a stupid mistake, you should HAVE READ MY THREAD!
You need to wait untill the Lollipop Factory images are published, then we can get a blankflasher and restore your bootloader.
Once your bootloader is working again, you can flash Lollipop without problems.
You need to wait 1 or 2 months.

Nope. I did read your thread after softbrick. And that's why I didn't install any OTA's after v5's.
I flashed 4.4.4. It's not an OTA!
I'm currently running 4.4.4 on 5.x bootloader.
Now what I'm asking is,
Would I be able to install 5.x OTA when I get it?
Before the factory image and all that thing.
PS: 5.x hasn't arrived for general public in INDIA yet. What I was trying was Brazil OTA.

[Q] How to install 5.0.1 GPE with working TWRP recovery and ROOT acces?

Hi all,
When I install a custom recovery, it(recovery) won't boot up because of CF auto root. I don't know why, it just doesn't work anymore. I've got the same problem on my Nexus 7 2013. But on the Moto G, this is harder to fix because the 5.0.1 GPE image for Moto G is not available yet. (You can only get 5.0.1 GPE using an OTA link)
I would like like to have 5.0.1 GPE with working TWRP recovery and root acces.
To achieve that goal, I'll need to do some tricky steps I guess.. Which I don't like to take.
The plan is to downgrade from 5.0.1 GPE to 4.4.4 GPE. There's no image of 5.0.1 yet, so this is the only way of getting a clean install (I guess.... please correct me if I'm wrong). Now there is this problem of Motorola phones which don't allow you to downgrade your bootloader.
4.4.4 GPE image does contain an older bootloader...
Now I found this tutorial: http://forum.xda-developers.com/showthread.php?t=2542219
It says: '"Downgrading:
The 1st command "mfastboot flash partition gpt.bin" will fail on 4.4.2 to 4.3 downgrade. Skip this command if you are downgrading and continue with the other commands, which should work."
I need to know if it's going to work for 5.0.1 to 4.4.4 downgrade.
After I have a clean install of GPE 5.0.1 I'll flash TWRP recovery and ultimately I'll flash the newest supersu.zip via TWRP recovery.
Can anyone tell me if the way I want to downgrade is safe? Or do you have other suggestions?
Please let me know.
Thanks in advance!
Best regards,
Daniel
