They are refer to the first four numbers here but you may also see were the first two are only mentioned which is "3A".
Thanks. To confirm, did you try rooting fresh out of the box, or was it already set up?

Sounds like your device was updated OTA. I don't think any of the 39's came with 1330
My 3919 serial CC came with 12072
So mine starts with a serial 3a06101. Is that rootable?

Very doubtful...to my knowledge, any CC that has a serial number that starts with "3A" isn't rootable. It's worth a try though, and won't hurt the CC to follow the directions and try.

Yeah, i try and try and all i get is a red light and nothing else, so i guess is a no go. Question, i dont know if i trust the otg cable so i used a cheap targus usb hub. Plug usb hub to morphie external battery pack, then plug cc into hub and usb into hub and tried that way. Should that work theoretically, if thr cc would be rootable?

Your setup is about as complicated as my initial one was! I used a Y-cable from a hard drive with a Mini-USB end along with a number of adapters to make it Micro USB plug and USB A port for the stick.
Yes, it's really just a matter of powering the Chromecast and USB stick, so if your Chromecast was rootable, it should have worked.
That said, some USB sticks are problematic, so you might want to try a different USB stick if you have one handy, just to be sure.
Are you sure that it wasn't allowed a connection to the internet? There is a post now that states a 3921 was rootable or 12072.

Better install PWNED! ROM on them now also as they will update if allowed to.
Serial number 3911 from Best Buy rootable. They had a fresh stock of Chromecasts in and a lot were either 3A or 392 at the front of the bunch. I almost gave up looking until I got near the back of them where there were a bit of 391s.
To anyone else going to get one, start at the back to increase your luck.

35First ask yourself, do I need to root? Then come back to see if you have possibility to root.
See: Root Mini-FAQ: What's the big deal with root? and Why should I root?
For help with FlashCast, see the FlashCast: Quickly and easily mod your Chromecast thread and Rooting with FlashCast Mini-FAQ
For help with HubCap, see the HubCap Chromecast Root Release! thread.
For help with Flashcast-AutoRoot, see the Flashcast-AutoRoot thread.
Note: THANK YOU to all the folks who contributed reports to the first incarnation of this list. Your help made it possible for many other users to pick winners from their local stores. Now that we're in the second generation of root (and unrootability), it was time for a revamp.
At the core, it's not the serial number that determines whether a Chromecast is rootable, but rather the firmware build on it. However, because Chromecasts ship from the factory with a specific firmware build, we can use the serial number to predict whether a particular unit is rootable out of the box, or is unrootable because it has a firmware that is not vulnerable to known exploits.
Firmware builds >= 19084 are not rootable by current means.
Also, for Chromecast, "root" means to flash a rooted ROM that disables Google OTA updates. Any Google OTA update at this point will render a Chromecast unrootable, regardless of its serial number. If that didn't make sense, please reread the previous paragraph above.
Want root? Find your scenario below:
I KNOW MY FIRMWARE BUILD AND IT IS...
- 12072
-> Root with FlashCast or HubCap 12940 version - Greater than 12072, but less than 19084
-> Try root with HubCap 12940 version, if that doesn't work, try root with HubCap 16664 version - 19084 or higher
-> Sorry, you're not rootable
I DON'T KNOW MY FIRMWARE BUILD BUT MY CHROMECAST IS...
- NEW, UNOPENED, NOT USED, NOT REFURBISHED, NOT RECERTIFIED, NOT REPLACEMENT AND
NEVER CONNECTED TO INTERNET
AND ITS SERIAL NUMBER STARTS WITH...- 3922 or lower (ie, 38AD, 371C, 3612, etc)
-> Root with FlashCast or HubCap 12940 version - 3923 or 3924
-> Please determine your firmware build version without setting up and report it to me with your serial number before attempting root.
-> Build 12072 - Try root with FlashCast
-> Build less than 16664 - Try root with HubCap 12940 version
-> Build greater than 16664 but less than 19084 - Try root with HubCap 16664 version
-> Build 19084 or greater - you're not rootable. Are you sure you didn't get a used/refurbished/recertified/replacement unit?? - 3925-4A1F (MFG 10/2014 and earlier, or no MFG date on label)
-> Try root with HubCap 12940 version, if that doesn't work, try root with HubCap 16664 version - 4A20-4B20 (MFG 9/2014 to MFG 11/2014)
Note: This range is in flux - I have a 4A27 that had 15098 and another user had a 4A29 with 15098, but one user had an unrootable 4A20 with 20472
-> Please determine your firmware build version without setting up and report it to me with your serial number before attempting root.
-> Try root with HubCap 12940 version, if that doesn't work, try root with HubCap 16664 version - 4B21 and higher (MFG 11/2014 and newer)
-> Your Chromecast has firmware 20472 or newer and is not rootable.
-> If you determine your firmware build version without setting up is less than 20472, please report it to me with your serial.
- 3922 or lower (ie, 38AD, 371C, 3612, etc)
- SET UP BUT (CONTINUOUSLY) DISCONNECTED FROM INTERNET PRIOR TO AUGUST 1, 2013
-> Root with FlashCast or HubCap 12940 version - SET UP BUT (CONTINUOUSLY) DISCONNECTED FROM INTERNET PRIOR TO SEPTEMBER 4, 2014
-> Try root with HubCap 12940 version, if that doesn't work, try root with HubCap 16664 version - SET UP AND CONNECTED TO THE INTERNET SEPTEMBER 4, 2014 OR LATER
-> Your Chromecast auto-updated to firmware 19084 or newer and is not rootable. - REFURBISHED/RECERTIFIED/REPLACEMENT
-> Impossible to determine what build will be on the device.
-> Determine your firmware build version without setting up then proceed based on build number.
-> Build 12072 - Try root with FlashCast
-> Build less than 16664 - Try root with HubCap 12940 version
-> Build greater than 16664 but less than 19084 - Try root with HubCap 16664 version
-> Build 19084 or greater - you're not rootable.
Root method requirements:
- FlashCast method
- Firmware build 12072 (this exact build, no others) on Chromecast
- Powered MicroUSB OTG cable
- Compatible USB flash drive 256 MB or larger (most drives are compatible, a few are not, check the thread)
- HubCap method
- Firmware build 19084 or lower/older on Chromecast
- Powered MicroUSB OTG cable
- Teensy 2, Teensy 2++, compatible or similar device that has ported build (see the thread)
- Compatible USB flash drive 256 MB or larger (most drives should be compatible, check the thread)
3If I'm able to get a few rootable ones, would any of you be interested in obtaining them? I'd only charge maybe $3 over normal price because the drive is an hour there and an hour back (to help with the gas cost). I know there was at least 1 rootable one left the last time I went, and I didn't grab it because I figured they were still plentiful and didn't wanna screw anyone else that was trying to find one there, but this thread is starting to worry me. So, if I'm able to help out even one of you with getting a rootable one, I'd try my best. Just need to know if anyone's interested before dropping that much of my cash on something. I'd probably be buying at minimum 3 of them.3
Yes. See threads by Team-Eureka
But to be 100% clear... Chromecast root is not in the code itself, it's in the bootloader (see Mini-FAQ: What's the big deal with root?) - you need root to keep root. If you don't have root, you can't magically get root, at least not with the current exploit.
- (True) Stock
Automatically receives Google OTA updates Only root-capable if on original 12072 build. With current root exploit (FlashCast), any Google OTA update to will patch the root exploit, resulting in no more root. - Eureka-ROM
Requires root to apply (write with FlashCast).
Preserves root. Everything stock does (except for Google OTA updates), plus... Optional Team-Eureka OTA updates. Other fun features (web panel, Team-Eureka whitelist, etc) - Stock - No Updates
Requires root to apply (write with FlashCast).
Preserves root. No OTA updates. No extra features. It's Stock minus the OTA updates that would kill root.
You never want to write a true Stock update to a rooted Chromecast, as that will irreversibly kill root.
So why is there a Stock - No Updates version if Eureka-ROM does everything stock does and more?
Because Google release OTA updates when they're done, but Team Eureka needs some time to analyze the source, add the Eureka-ROM goodness, and check for introduced bugs. This isn't Team Eureka's full-time job (nor do they get compensated save for donations from appreciative folks like me), so it takes time.
The Stock - No Updates version is there for people who just can't wait for the corresponding Eureka-ROM build to release and must have the latest Google-released features immediately. This sometimes happens if a new app requires some firmware-level enhancement that's only in the newest build. For example, when the Cast SDK 2.0 apps released, they required the newest firmware at the time. - 12072
