The userdata.img file is a blank partition. It is used to reset the userdata partition to its factory state (completely empty) and is not needed if you're just using the stock images (boot.img, system.img) to update to 4.1.2

Okay, that's what I thought it was too, but then why is it 140MB? I mean I could see it being a few kilobytes for a directory table, or the size of the partition if it was an uncompressed image, but 104286KB for the Nexu7 and 137555KB for the Galaxy Nexus seems pretty arbitrary to me.

Hi,
I have stupidly renamed my official htc rom cwm backup.
And cant remember the original name!
cwm says that here is a md5 sum mismatch!
Has anyone got a backup they could zip up and upload?
If not how to get it back
Can i flash the .img files in fastboot?
RUU? Would that get me back too stock HTC 2.2.1?
Make sure that there are no spaces in the new renamed folder. Then it may clear the md5 checksum error.
And you can also flash the img files from fastboot.
Commands are
fastboot erase boot
fastboot flash boot boot.img
fastboot erase userdata
fastboot flash userdata data.img
fastboot erase cache
fastboot flash cache cache.img
fastboot erase system
fastboot flash system system.img

figured it out!
Hi there
I've built Firefox OS for the Galaxy Nexus but I'm struggling to find a way of creating a flashable zip to distribute.
This is my first ROM that I have successfully compiled, but everything seems to be working so I wouldn't mind sharing it with the rest of the internet. Any tips?
Thanks!

After building from the B2G directory (the folder from where you run ./config.sh and ./build.sh) you should locate boot.img, userdata.img and system.img and copy them over to a folder, then you can flash using fastboot via:
adb reboot bootloader
fastboot flash boot boot.img
fastboot flash userdata userdata.img
fastboot flash system system.img
fastboot erase cache
fastboot reboot

Ah didn't know this thread had replies so sorry for a bit of a bump. I was kind of after directions on how to create a flashable zip? It's just that I was aiming to avoid end users from using adb and fastboot. Do you know how to create a flashable zip instead?
Thanks for the guidance!

Took'em long enough!
Is it possible to flash the factory image with CWM recovery to get stock android on the nexus 7 lte version? Will it delete the files on sd card?
^Aside from boot you can not flash the image files through recovery but there's no need.
Just fastboot flash the bootloader.img system.img and boot.img. Done. Won't erase anything.
(Check if there's a new radio if so flash that as well)
Or run the flash-all file but delete the -w in it or it'll wipe your data.
Is it possible to extract a copy of a system image from an updated G4+? Like the boot.img, recovery.img, system.img, etc? To be flashed in fastboot
Yep. You have to flash TWRP and backup all img's. They'll appear with 'win' extension, so just change them to 'img'.

Flashfire app has a fastboot compatible image backup feature.
I need the files to fix my g4
Somehow I have lost my OS. Phone will not boot. Can get into Recovery but that's it. Have tried installing factory image and Pixel experience nothing works. Please, I need help.

Thanks. This doesn't help. Flash-all command doesn't work.

Flash it separately
fastboot flash system (drag the system image)
fastboot flash recovery (drag the recovery image)
fastboot flash vendor (drag the vendor image)
fastboot flash boot (drag the boot image)
