I've got the latest version of CleanROM installed on my Nexus 7 2013. Originally I had tried to flash the latest factory image (4.4.2) via USB/TWRP, while on JellyBean, after wiping and reformatting everything via TWRP. It wouldn't work, so I eventually tried flashing the latest version of CleanROM (based off of 4.4.2) and that did work. So, everything is fine on my device, but I'm wondering how to flash Google's official 4.4.2 image now. Was it because of the bootloader I had prior to trying to flash the official image? Was CleanROM able to successfully install the bootloader because it doesn't require that you be unlocked/unrooted?
P.S. Figured it out on my own...
I am going to purchase a Nexus 7 2013 and will be wanting to unlock the bootloader and root the device straightaway. I would be grateful if someone could tell me the best way to go about this. Should I carry out these tasks with no ROM updates applied, i.e. on 4.3 or should I update to Lollipop first? Thanks in advance.
With the nexus 7 its as simple as typing fast boot OEM unlock, but here is a more comprehensive guide on the matter. http://forum.xda-developers.com/showthread.php?t=2381698

Unlock the bootloader before doing anything else, as it will wipe your data in the process.
If you plan on staying with the stock rom, don't bother rooting or installing a custom recovery until you've updated all the way to lollipop, as it can cause the ota updates to fail and you'll just lose root with each update anyways. Beware of taking this route though, the are lots of posts around saying that the latest ota update bricked devices. Might be safer to fastboot flash the latest factory image directly.
If you plan on using custom ROMs, go ahead and root it and install custom recovery then flash away to your heart's content. You may need to update the bootloader to latest version first to successfully flash lollipop ROMs though. I think its version 4.04, and there are flashable zips for doing this somewhere around here that worked great for me.

I unlocked the bootloader, updated to Lollipop 5.0.2 by flashing the latest factory image, then rooted and flashed TWRP. I would now like to flash custom ROMS. You mentioned I may need to update the bootloader in order to successfully flash custom Lollipop ROMS? Am I correct in thinking I will have the latest bootloader, now that I have updated to Lollipop 5.0.2? Thanks.

Yep, you're correct. If you flashed the factory image, you should already be on the latest bootloader. :good:
By the way, 5.1 factory image finally was released today for this device.

Great, thanks for letting me know. Do you recommend I update to the 5.1 factory image before I flash any custom ROMS, or doesn't it matter?

Doesn't matter, though you may wait for the custom ROMs to update to 5.1 so they will have the latest binaries.

N7 2013 LTE -> I was using factory Marshmallow and just unlocked bootloader, rooted and installed TWRP.
Can I flash any ROMs now? eg going back to a Android 5.1.1 ROM? Is it just a simple ROM flash?
Yes. Do check the bootloader version anyways. It should've been updated to marshmallow version, shouldn't be a problem

Thanks. So as the boot loader is updated for marshmallow, I don't have to downgrade the bootloader or radio when going back to lollipop?
My girlfriends Nexus 7 (2013) razorg has TWRP recovery and is rooted by flashing superSU. Firmware is 5.0.2, Build Nr. LRX22G and OTA to 5.1. is announced.
Now I want to update it to 6.0.1. and root it again. As I read about this device the best way would be to use a factory image and flash a superSU again.
Now my problem is to find out what version of superSU is the right one. Some infos are outdated and differ a lot.
I want to flash razorg-mob30x-factory-1cb173c1.tgz factory image.
Which version of superSU is the right one to use?
Thx in advance.
The latest 2.76 works fine.

On razor that is, I don't have the mobile version. Probably doesn't matter.
Hello,
I have installed the last 7.1.2 beta + Franco kernel on my phone. And i have received the ota to install the stable version, but it fails because the kernel is not the original one I guest...
I have downloaded the factory image, but I'm not sure if i will lose my data if i install it using flash -all script...
What's the best method to update to the stable version without losing all my data/configuration?
Thanks!

If you rooted, use flashfire.
