Chromecast ROOT'ed SN: 3727xxxxxxxxx

Moded via FlashCast 1.1.1 :good:
[Google Chromecast] bhiga:
Good to hear you got it working. The whole HDMI handshake thing can be troublesome at times.
[Google Chromecast] fly4awhtgye:
The parts are here. Gonna root this Chromecast this weekend hopefully. Thanks for this thread packed with useful info.
[Google Chromecast] raichur0xx0rz:
So, once you've gotten FlashCast ready, which formats the USB Drive, is it okay to re-write the .bin file to the USB Drive in attempt to use the same drive to flash another Chromecast? Or should I just use another flash drive?
[Google Chromecast] bhiga:
Once the FlashCast drive is prepared, you don't need to re-write the .bin unless there's an update to FlashCast itself.

Just stick your ROM/mod on there and boot it on the next Chromecast.
[Google Chromecast] fly4awhtgye:
So I'm new to Chromecast and the rooting process didn't go exactly like the video tutorial...This screen below means I am good though, rooted with Eureka and can not Iose root from any OTA update, correct?

I put l posted a flowchart and troubleshooting, see my signature in other posts. :)

Just be sure to keep Chromecast powered through the entire update process through reboot and you're good to go.

Hi Expert,

I was following through all the steps but I'm still failing when installing the eureka_image.zip. here are the logs from flashcast

I can see there no image found and it is quite strange.

any clue or advise to help me solve this problem, thanks in advance..

UPDATE: Problem solved, how stupid I'm renaming the file to eureka_image.zip.zip :D

screwed up my chromecast

I used an old powered usb hub rather than the recommended cable, I may have even plugged the wrong power adapter into my usb hub. I never saw any light go on on my usb stick, nothing seemed to be happening so i pulled the plug. I think it's unrelated to the software, but now my Chromecast will not boot at all. it flashes violet for a second when it has power and then nothing, and it gets really hot.

I did use this chromecast once in a situation where the wifi was not working, So it did work in the past. I know it did not update. Now it's a very hot brick.

Just posting incase anyone has an idea on a recovery for it.
[Google Chromecast] bhiga:
Can you check what power supply you plugged into your hub? I have the bad feeling you might have used a power supply with too much voltage and that might have fried something in Chromecast...

I accidentally did this with a USB wireless adapter once and it exhibited the same symptoms - it would light up and proceed to overheat.
[Google Chromecast] aibandit:
In these instructions shouldn't this bit

Be before this bit?

I kept thinking I was flashing something like a bios on the chromecast itself and waiting for the reboot. After following instructions word for word step by step as written I kept seeing the red LED and no reboot I started trying to get my build number (though I have a compatible serial) hopefully I didn't accidentally update.
[Google Chromecast] bhiga:
No, those two bits are functionally identical.

On a newly-prepared FlashCast USB stick, the first boot simply partitions the drive so it can accept updates. It does not flash the Chromecast. You only need to prepare it once, unless you rewrite the FlashCast .bin image to the stick or otherwise erase/reformat the stick).

After the stick has been prepared it should mount on a computer as a volume with name FLASHCAST. Then you can copy the ROM or mod to the stick as eureka_image.zip

Then you boot FlashCast on Chromecast and it'll flash the ROM or mod.

Follow the flowcharts in the Rooting with FlashCast Mini-FAQ - the first flowchart is for preparing the FlashCast USB stick. The second flowchart is for actually flashing a ROM or mod using the prepared stick.
[Google Chromecast] aibandit:
I see, well for whatever reason my chromecast didn't reboot after preparing only after adding the mod, though both the flow chart and these instructions say it will.

Anyway it ended up working
[Google Chromecast] bhiga:
Interesting, it has for me on both sticks I've used. Good that it's working though. Web panel is the easiest way to check as the Team Eureka boot logo doesn't always show due to delay in the TV "picking up" and displaying the signal.

3929, not rootable (black screen)
[Google Chromecast] mloftus11:
Sorry if this has been explained but I did not see it. Will this work on Chromecast that has been updated by Google? I.E. one that has been used in non rooted capacity?

Thanks
[Google Chromecast] bhiga:
No. FlashCast requires a vulnerable bootloader which means a rootable Chromecast. See links in my sig. :)
[Google Chromecast] mloftus11:
Thanks for the help
[Google Chromecast] m0ngr31:
So I got a Chromecast forever ago. I booted it up once and played with it for a minute, but couldn't figure out what I'd do with it at the time (really got it hoping for an XBMC port).

I had completely forgot about it until found it yesterday just sitting there so I browsed the forums hoping to see XBMC, but that doesn't look like it'll ever come so I was going to try Eureka.

My serial number starts with 3625, so I figured I'd be good to go. So I downloaded flashed and plugged everything into my OTG cable. Held down the button and plugged it in and the red light just stayed on and nothing showed up on my screen.

Am I to guess that it got updated at some point so it's unrootable now?
[Google Chromecast] bhiga:
Sorry, yes, unless you see a row of multi-colored dots slight to the right of screen center along with the red light.

Otherwise, if it had Internet connection and was powered up, it automatically downloaded an update which patched the vulnerable bootloader.

The serial number test is not to check the hardware, but rather an educated guess as to whether it has the original build 12072 firmware and its vulnerable bootloader.
[Google Chromecast] m0ngr31:
Ok, that makes sense. It's too bad. I must have left it plugged in for a few days after I got it. Thanks for the help.
[Google Chromecast] bhiga:
Makes me sad inside to know another device has falled out of root-land. I regret not saving more of the rootable souls when I had the chance... :(
[Google Chromecast] SunamY:
Is it now possible to root chromecast with serial 42xx?

Gesendet von meinem Nexus 5 mit Tapatalk
[Google Chromecast] bhiga:
No, unless by some miracle is arrives to your with the original build 12072 firmware.

So far this has not happened.

If/when things change, I will update the Rootable Serial Numbers thread.

The serial number remains only a guideline, the true test is what firmware build the unit has. One member recently received a 3C02 serial that did have the vulnerable 12072 firmware, so it's not impossible to have a newer unit that's rootable, though it is highly improbable.
[Google Chromecast] TimV_:
I have a root capable chromecast but i get the startuo isseus screen from google what am I doing wrong?
[Google Chromecast] bhiga:
Is it already running a rooted (root preserving) ROM?

It shouldn't have startup issues fresh out of the box.

Serial number is a guideline not a guarantee.

I have a brand new in box chromecast from launch day. Never did get around to playing with it. Anyone have some quick tips I should do to avoid losing the option to root? Thanks guys :)

I have just released FlashCast version 1.2. A changelog and downloads are available on GitHub here. Please note that the minimum USB drive size has increased from 128MB to 256MB with this release.
[Google Chromecast] jamesking420:
Cool! Flashing this to my USB stick later tonight :)

---------- Post added at 02:37 PM ---------- Previous post was at 02:35 PM ----------

What does this mean?

"Improved Wi-Fi configuration parsing logic, which will improve compatibility with future OS releases"

I thought Flashcast was only for flashing ROMs so we wouldn't need wifi for it?
[Google Chromecast] bhiga:
You don't need WiFi for Flashcast, but it does make Chromecast available via wireless ADB/telnet/SSH while running. That's why it gives you access info on the screen. :)
[Google Chromecast] jamesking420:
Hey,

The flashcast welcome screen still says "if it's white" on the left hand panel.. I think what you now mean is "if it's flashing white".

Great work though!

James
[Google Chromecast] tchebb:
Yeah, we realized that we hadn't changed that just as we were prepping the release. Since we already had everything built, tagged, and tested, we decided to leave it be for this release. It'll be corrected in the next bugfix release (1.2.1), though, which we plan to have out as soon as Google releases the kernel source for build 16664.
[Google Chromecast] wptski:
I've been flashing away from the TV since day one.

Anyway, same OTG cord, flash drive and have done this numerous times. LED will not turn white, tried twice. Plugged back into TV and all is still good. Plugged flash drive back into PC, wants to format and the FAT 32 tag is gone but I can't remember if this is normal??

I guess that I'll just revive flash and try again some other time, maybe download Flashcast again.
[Google Chromecast] bhiga:
It's normal to not have the drive mount on a PC if it has been freshly-written by win32diskimager or dd

The first boot on Chromecast formats the FAT32 part.

See Mini-FAQ: Rooting with FlashCast

Also, you might want to try a different USB stick. The last time I had trouble (constant red LED, no white), the USB stick I was using had gone bad.
[Google Chromecast] wptski:
Nah! Need a new operator.:D Haste makes waste.

Startup Issues splash screen

Hello guys,

After following the procedure precisely, is the "startup issues" splash screen THE SIGN that the chromecast is not flashable, or should it at least allow you to boot to the USB stick after the stick has been given the flashcast-1.2.bin treatment via Win32DiskImager?

Ta

Mark
[Google Chromecast] bhiga:
Depends. Could be the sign of a stuck button too.

-= this post enhanced with bonus mobile typos =-
[Google Chromecast] ddggttff3:
If its the startup issues screen with the yellow warning image, that means your device is not rootable as you have a unexploitable bootloader. That error image was added to the bootloader in build 16041 (or was it 15250?) Either way, its unrootable.
[Google Chromecast] fredphoesh:
Ok tx... i wasn't sure what would be the point at which the process was blocked... dang. A UK sourced SN 4216... is not rootable.

Mark.

---------- Post added at 08:29 PM ---------- Previous post was at 08:27 PM ----------

yeah, i guess... though it does not feel stuck at all, pops in and out as you would expect...

its more likely just not rootable unfortunately.

i'll have to access netflix usa via vpn on my pc.

cheers

Mark.
[Google Chromecast] bonjurkes:
So you mean that even chromecast is not rootable, it should show something on screen, instead of plain black? I am trying my chance to have a possibility to root my chromecast, it lights white for one second but then stucks to red, when I connect it to tv, nothing appears.

Does it mean that it's just not rootable, or something is wrong with my cable setup or usb?
[Google Chromecast] ddggttff3:
It all depends on what firmware is currently on the device. That error screen only will show up in build 15250 and above. Anything below would not show an error screen (ex 13300) but it would still fail to root as it has a patched bootloader. What serial# is your device? that is normally one of the best ways to see if you device is rootable or not.
[Google Chromecast] bonjurkes:
It is 3B08 , I knew that it's non rootable but still wanted to try my chance but it looks like, I am out of luck
[Google Chromecast] pmcdunnough:
I rooted my Chromecast using Flashcast v1.1.1 and Eureka-rom 2.0. Worked great. Is there an easy way to upgrade my USB stick to Flashcast 1.2 without redoing everything? That is, can it be done without using the Chromecast itself via some kind of patch? Or, should I be using a new USB stick and redo everything?

Thanks,

Philip
[Google Chromecast] bhiga:
You do not need to re-flash your Chromecast. FlashCast lives on the USB stick, not on Chromecast. Eureka-ROM has its own embedded FlashCast to apply its OTA updates, but that will get updated with the Eureka-ROM OTA.

All you need to do is write the FlashCast .bin to the stick, then boot the stick in Chromecast to get its FAT32 partition prepped. Just takes a few minutes, and you can use any rootable/rooted Chromecast.

If you want, you can use a new USB stick... you'll have to if your current stick is only 128 MB.

chrome cast got unplugged while updating

Ok ive had my chromecast Running Eureka Rom with no problem's for along time. My wife unplug's the chromecast in the middle of updating.It now show's chromecast not Eureka when booting now.

I've went to starting the process all over again starting with installing flashcast on my zip drive. it reformats zip drive to FAT32 like its supposed to.

Now here's the problem ..... when trying to install flashcast from zip drive to chromecast it doesnt work , I'm getting white light when i plug in with button pushed an amber color light comes on chromecast . Any idea's??
[Google Chromecast] bhiga:
Make sure you have named the ROM file eureka_image.zip not eureka_image.zip.zip

See the rooting with FlashCast mini FAQ in my sig for example.

Best to turn off Hide file extensions for known file types to avoid this type of problem.

If that isn't the problem check the log file on the stick.

Do not power Chromecast normally until you get Eureka-ROM back on.

[Google Chromecast] larrypetty:
Well looks like Google some how updated my chromecast. DO NOT UNPLUG ( OR YOUR WIFE UNPLUG ) WHILE EUREKA UPDATES ! ! !

Not a happy camper atm

How to help ?

Hi,

I am a french chromecast owner, and my chrome cast seems to not be rootable (version 166664, and a serial starting with 42...).

I would like to know how I could help to find a way to turn it rootable...
[Google Chromecast] brs608:
There is no current way to make it rootable. Boot loader has been patched and no new root method found with the new bootloader.
[Google Chromecast] Asadullah:
in the sgs4 section of xda one of the developers or someone has the rsa keys that qualcomm uses to sign their aboot would that be able to help the chromecast?
[Google Chromecast] tchebb:
No. The system-on-a-chip used in the Chromecast is produced by Marvell, not Qualcomm.
[Google Chromecast] cmb3497:
Same thing happened to me, although I don't think that our devices were updated. Actually, I'm not entirely sure what happened to my CC, as one day it just wasn't showing up on my TV as a selectable input (I have a Samsung, it wasn't showing up in anynet devices), so in my infinite wisdom I unplugged and plugged it back in, only to realize that Eureka MAY have been updating itself. But, if we were rooted w/Eureka, we should have been protected since Eureka blocks OTA updates, no? I'm still trying to fix my CC but am having a hell of a time getting Flashcast to work again (I remember it took me forever last time I tried to use flashcast, and I was doing one stupid little step wrong but can't remember what that was for the life of me). If I make any headway I'll give an update, but in the meantime, don't give up hope!
[Google Chromecast] bhiga:
Prior to the 16xxx builds of Eureka-ROM there was a part of the update process that if you lost power it left the device with unpatched stock OS, which then, after booted, would try to retrieve a Google OTA.

This issue has been fixed in the current Eureka-ROM builds and I believe is part of the reason the minimum USB stick size went from 128 MB to 256 MB.
[Google Chromecast] cmb3497:
Huh. Well I'm not sure what really went on with my CC. It doesn't show up as detected on the network using my phone and PC to set it up, and isn't even listed as an input on my TV when I plug it in. I'll keep digging and see what I can find, and if I can't fix the dang thing.
[Google Chromecast] bhiga:
That sounds like a different issue, perhaps power supply gone bad or TV not supplying stable USB power.

-= this post enhanced with bonus mobile typos =-
[Google Chromecast] cmb3497:
Well I just got home from work and it looks like my PC chromecast app now sees the device. It has not been set up yet, however, so I believe this means it has NOT taken any Google OTAs. If I am correct, I should be able to still get Flashcast on it and Eureka and all that good stuff. Is there a way I can check which firmware it runs without setting it up on my network? I'll check the stickied threads/FAQs in the meantime. Here's hoping this works, it took me forever to hunt one of these down at the local Best Buy...
[Google Chromecast] bhiga:
If you haven't given it WiFi credentials and have a powered OTG cable, just try to flash it.

You can also check the firmware build without setting up - check the post linked in the root mini faq or rootable serial numbers thread.

-= this post enhanced with bonus mobile typos =-
[Google Chromecast] cmb3497:
Tried to flash it, no dice there. I remember it took me forever last time to get it to actually flash, but I can't for the life of me remember what I was doing wrong that first time. All I know is that it was some trivial stupid step that I was overlooking, and I feel as if I may be doing it again... Anyway, when I plug the chromecast into the TV (have NOT set this up via wifi yet), all I get is a black screen. The LED goes white, flashes red a few times, then goes solid white. Same deal when trying to get Flashcast on it. Tried via powered USB hub and computer USB port to no avail. It also kind of looks like my network doesn't even recognize it anymore. Strange goings-on with this thing for sure, hopefully I can get it up and running soon. I checked if my reset button was stuck, but it is not. Any suggestions?
[Google Chromecast] bhiga:
You should be seeing something when connected to a TV and booted without the button being held down.

If you can, use wall power to eliminate power supply questions.
[Google Chromecast] extrem0:
Probably your previous mistake was that the filename (eureka_image.zip) was written with .zip extension duplicated as Windows by default hides known extensions.
[Google Chromecast] cmb3497:
This is all I get, literally just a black screen. LED goes white, red, then solid white all in about three seconds. And to top it off, it doesn't show up on my network when plugged in. Could I have bricked it? I'm going to try a factory reset and see if that does anything.
[Google Chromecast] bhiga:
Try another TV if you have one, just to make sure it isn't a resolution or HDMI negotiation issue.

If factory reset doesn't bring an image then yeah it may be bricked.

-= this post enhanced with bonus mobile typos =-
[Google Chromecast] cmb3497:
Ugh. I sure hope it ain't bricked, it'll be impossible to find another rootable unit. Oh well. Off to try to factory reset and then if that doesn't work I'll have to scour every electronics store in town.
[Google Chromecast] Droid2drummer:
You need to always call the manufacturer. Tell them its shutting off constantly for no reason. They will or should send you a jump drive that will basically flash the system back to the unit. I do this on all my devices. If the say no call back and tell them you were told to ask for one and you did the factory resets and now your ready to give your adress... If your planning on hacking its always good yo have one.
[Google Chromecast] bhiga:
While this is good advice for regular Android tablets and phones, Chromecast is far from a regular Android device.

There's no card slot or built-in USB port, though the latter can be added for flashing purposes via a powered USB OTG cable.

Only units with the first-released firmware (build 12072) bootloader are rootable. Once set up, the firmware and bootloader OTA updates automatically without the user being able to refuse. Units that have been auto-updated and units that shipped from the factory with a newer build are not currently rootable.

Only Google has (?) a flasher that can be used by non-rootable/rooted units.

Because of all the legal agreements required to get the content providers on-board, Google is being very cautious about rooting and any other reverse-engineering. Rooting is actually against the terms of developer agreement, so a developer can't legally create an app to root using the Cast SDK.

It's a $35 device

Thus Google is far more likely to just replace the unit, rather than sending the consumer a USB OTG cable, and a flash drive that could potentially be used for reverse-engineering, rooting, or other purposes.

Problem is, replacing the unit will likely result in receiving one that already has a newer firmware build and therefore isn't rootable.

But hey, if you can get Google to send you flash drive, that would be great for root research and other exploits. Especially if it forces build 12072 onto it!
[Google Chromecast] cmb3497:
Not sure if this thing is bricked, but I am at an absolute loss as to what the hell is going on with it. Tried the factory reset, but it refuses to cooperate. I've held the button down for like two minutes straight and the light just stays constantly white. My last end-around is to try and set it up via my laptop because it decided to show itself on my network (that is, if I can get it to show up again), and factory reset from there. I'll keep the thread posted as to what happens next. Even if it is bricked, this could be a good learning experience for some other users, and the more data the merrier.
[Google Chromecast] Diomorgan:
#492 posts, so forgive me if it's already been said, but it would be nice to write in the 1st post "Chromecast officially began shipping in Canada and Europe on March 19, 2014. So far European models seem to start with 41xx, which of course means they are not rootable." , from the nother Q&A thread.
[Google Chromecast] Murmel2k:
Hi,

yesterday I've recieved my Chromecast with 38xxxxxxxxxxx serial, which I've bought in the US. I've rooted it and everything went well. But I wasn't aware, that I would need the Flashcast USB drive afterwards to flash additional addons. So I've used my 64 GB main thumb drive for rooting my Chromecast. Is there a easy and fast possibility to create another Flashcast USB drive without re-rooting my chromecast? I have alot of smaller drives, which I would have used, if I'd have known, that I would continue to need the USB drive after rooting my chromecast.

Thanks
[Google Chromecast] rekids:
Not sure may be able to make an image in something like Maxblast which works great and is free of you have a Seagate or old Maxtor drive connected to the system. It's a nice drive cloning software written by Acronis. See if it will allow you to make a full image of it and let us know.
[Google Chromecast] pmcdunnough:
Hmm ... I can't even recall which USB drive I used. Don't upgrades to Chromecast just come over the air once you have installed the rom? Why would you still need any USB drive?
