Chromecast - Brazil

Hello, I am Brazilian Chromecast the User. Does FlashCast works in 4416101XXXXZ model? :rolleyes:

the numbers in this series are numbering 4 . My FW is Version 17977, Some tool to downgrade FW?
[Google Chromecast] rekids:
Nope and nope.

No way to down grade firmware due to signature being upgraded to not allow older firmware.

Firmware that is currently rootable is ONLY 12072. Serial numbers above 3921 generally are shipped with newer firmware and are not rootable.

Sorry, eBay does have some every so often for sale that are new units that are rootable for reasonable price. I have gotten 2 that were listed misspelled words for under $50.
[Google Chromecast] micheldarkcore:
:D

Ok, thanks for the information. I believe that in the future there will be a solution to downgrade to the new FW . :D

Give it now a way to root a used Chromecast?

[Google Chromecast] rekids:
I personally have replaced the newer bootloader with the older and resulted with a non booting CC. Changed the kernel as well since it read at least partially before the bootloader and still would not boot. So after a bit went back too clone a rooted CC with customer key byte for byte and it would not boot. At this point I found that some time soon after the 12072 the signature check was updated on the SOC and since there is no know way (the suspicion is fuse is blown) to JTAG the SOC (not to mention no data sheets available) we are not able to change the signature in the SOC.

The idea is great to change the firmware by removing the NAND and re-program it but in the end the fail proof of downgrading proved to be so far "fail proof". Our best hope is a new exploit. And if some one who knows code well enough to find and use one could get a full dump from those that deal with the firmware.
[Google Chromecast] bhiga:
Not yet, because if it has been used, it most likely has been connected to the Internet, and if it has been connected to the Internet, it will have automatically updated to something newer than the original 12072 build, thus losing root.
[Google Chromecast] helpmeplis:
Thanks for this thread. I found an unopened cc for 37$ with very low serial. Opened it and it was rootable. 3 weeks later I receive my otg cable and rooted without any issues. I'm happy :D
[Google Chromecast] rekids:
By any chance was it the one I posted a few days back? Hope so I waited a few hours and could not wait any longer went to buy if no one had and it was sold
[Google Chromecast] helpmeplis:
No, I found it asking eBay sellers
[Google Chromecast] rekids:
Nice
[Google Chromecast] rippernz:
I finally received my CC in Australia today from the ebay seller above.

Serial start 3731 and is now rooted

FlashCast and Eureka up and running
[Google Chromecast] ddggttff3:
For those of you who are stuck with unrootable serial devices, do not fret. Even if it's not rootable today, it may be tomorrow. No device is "Hack/Exploit Proof" ;)
[Google Chromecast] ClearD:
Hmm...
[Google Chromecast] Kyonz:
Definitely no device is exploit proof, I wouldn't be surprised if someone found a way around it.

I mean the device has been out for a long time now right.
[Google Chromecast] hiratafabio:
Waiting for news coming from DEF CON 22 which starts today!
[Google Chromecast] ClearD:
New root method should be revealed around 10 am on Saturday the 9th. That's when gtvhacker gets to speak. And they may actually reveal not one, but two new root methods for the Chromecast from what I read.
[Google Chromecast] ddggttff3:
Mind if I ask where you read this? I have yet to find anything saying they are releasing a chromecast exploit.
[Google Chromecast] bhiga:
http://blog.gtvhacker.com/2014/google-nest-exploiting-dfu-for-root/

Scroll down past the block graphic.
[Google Chromecast] Lizard:
Is there any news on the new root? I looked around but the gtvhacker pages only mention the old exploit.

And the DEF CON 22 talk is also over.
[Google Chromecast] ddggttff3:
No chromecast related exploits or roots were released at defcon or blackhat this year.
[Google Chromecast] mazzanet:
I just rooted 2 x 3C01 devices with HubCap.
[Google Chromecast] samteeee:
A big Thank you to Team Eureka & GTVHackers for the HubCap exploit.

Just got my NIB CC Canadian Version S/N: 4107******** Rooted with HubCap 16664 image.
[Google Chromecast] tim1089:
3C04rootable?

I bought a refurb Chromecast serial number 3C04. Anyone know if it is rootable
[Google Chromecast] Asphyx:
At this point the serial number is meaningless....

All CCasts can be rooted provided they have not been Updated past 17xxx....

If it ran a recent update to 19xxx it is no longer rootable!

Anything with a Rom Earlier than that is still able to be rooted.
[Google Chromecast] bhiga:
Yup, serial number is only good for finding original 12072 US Chromecasts. Beyond that, it's just time... And with a refurb, all bets are off because who knows what the repair center did to it before sending it back out... My one that died went to Fremont, CA (darn, I should have driven by while I was there)... who knows where else they're accepting and/or repairing them.
[Google Chromecast] waiters:
Yes 3c is rootable if you don't take th OTA
[Google Chromecast] skivnit:
I have a 3c 12049 I'm guessing that's rootable.. Problem is there is no otg cable here :(
[Google Chromecast] bhiga:
Yes it can be rooted with HubCap but once it connects to Internet it will update to 19084 and no longer be rootable.
[Google Chromecast] skivnit:
I meant 12940 so I won't connect it till I buy the otg cable, I only know about the firmware as I connected it through a non Internet connected wifi and saw it on the app
[Google Chromecast] bhiga:
You also need the Teensy 2 or other similar device for HubCap. FlashCast can only root 12072.
[Google Chromecast] skivnit:
Yup I just read, so I won't root it as in Morocco we don't have Amazon, and no teensy
[Google Chromecast] Mad07:
Yesterday I've buy a CC brandnewin Germany, look that it is not a retail or however stick and a very low SN-No.. The serial is a a 4114... (biggest one was 43xxxxx ) and a GA 3A000... device . The stockfirmware is 15098. Now I'm still waiting for the OTG and teensy programmer .....

---------- Post added at 11:52 PM ---------- Previous post was at 11:45 PM ----------

The OTG cable is not the biggest issue : Make it by yourself :

[IMG="otg cable"]http://stech3.firstpost.com/wp-content/uploads/gallery/2012/jun/difference_circuit_271738111300_640x360.jpg[/IMG]

The big different is only the bridge betw 4&5. The powersupply (5V) is connected 1&5
[Google Chromecast] stonejag:
Just successfully rooted a 3C30 - it arrived running 15098, so still vulnerable to HubCap. I let it connect to my home network but only with the 'net connection unplugged so it couldn't update. Imagine there'll be an enormous amount still to be sold before they start coming out of the box with the latest firmware, so we should be OK for a few months at least :)

Stone
[Google Chromecast] Asphyx:
Don't allow it to update or you will not be able to root....

Use the 12XXX hex file to root when you get all you need and whatever you do do not let that CCast update from google!
[Google Chromecast] Mad07:
In the meantime the 2nd CCis at home... also with the stock FW 15098 on the device. The interesting thing is, that the 12xxx files doesn't work so as expected. The 16xxx was the right decision ;)
[Google Chromecast] foxgalaxy:
Not rootable

Not rootable. May try teensy method.

SN: 3A20

Firmware: 15098

Package: Refurbished
[Google Chromecast] yaw hide:
does anyone know if a chromecast starting with 41 is rootable?

I dont want to buy any extras incase my chromecast is screwed...
[Google Chromecast] bhiga:
Anything not new in box less than 3921 will need to be rooted with Hubcap if it's still rootable (firmware prior to 19084)

Can't tell by serial on international versions. Should be Hubcap-able unless it's been updated.
[Google Chromecast] rdmrocha:
would like to share that today I received a 3C12 chromecast bought during Amazon's Black Friday deals and it's 12940 so I expect it to be rootable via HubCap
[Google Chromecast] Ikarisan:
Hi!

I bought a CC with serial 4116***** and firmware 15098 (Germany). It seems not to be rootable. The process works fine until it shows the FlashCast screen on TV. The LED remains red and a few seconds later it reboots to stock Google CC. :rolleyes:
[Google Chromecast] bhiga:
Wait a minute...

If it has 15098, it should still be rootable via HubCap.

Sounds like you are using the HubCap method. Try a different USB stick. FlashCast is not compatible with certain sticks because of the way they mount.
[Google Chromecast] Ikarisan:
I take back everything I wrote.

My CC is rootable but I tried to root as described in https://www.youtube.com/watch?v=S2K72qNv1_Q. That was wrong. :(
[Google Chromecast] bhiga:
That was just a demo. Follow what's posted in the HubCap thread.

Plug in power last while holding down button until the Chromecast LED goes Red, then release button.

If it doesn't work at first, check that you have the correct Teensy 2.0 (regular) vs Teensy 2.0++ (plusplus) hex file programmed, and if it still doesn't work, try the version for the other build (12940 vs 16664).
[Google Chromecast] XartBing:
Try 16664.hex instead of 12940.hex

I had a similar issue with 47xx international Chromecast which had "build_version":"15098"
[Google Chromecast] sweetboy02125:
I have 4A09...., can it be rooted?
[Google Chromecast] bhiga:
If it hasn't accepted an OTA update, then probably yes.

I have successfully rooted a 4918 unit and so far nobody has reported units shipping with build 19084 or newer yet. At some point it will happen though, and the door to root will close once more.
[Google Chromecast] Mad_Lion:
I have maybe a little silly question but I'm new to Chromecast. I have Chromecast with Firmware version 15098. What are my options for root?
[Google Chromecast] bhiga:
Do not let it connect to Internet (or it will update to non-rootable version), and use HubCap exploit.
[Google Chromecast] dro1dy:
As expected, serial number:

4812101

was not rootable. powered OTG used. dd used to transfer bin to a 16gig thumbdrive
[Google Chromecast] bhiga:
If it has firmware older than 19084 it should be vulnerable to HubCap.
[Google Chromecast] automechcanic:
I recieved a ccast for gift and tried it out before learning about this. Serial # is 4903 on box and device. Has recieved OTA update. So the obvious stupid question,(sorry have to ask). Is my device currently unrootable because of the update?:crying:
[Google Chromecast] bhiga:
Sorry, yes. If it gets OTA update before being rooted with custom ROM, it will update the bootloader and patch the HubCap vulnerability, then no way to root with current means.
[Google Chromecast] automechcanic:
Thanks for the reply.
[Google Chromecast] Crazor:
Yesterday, I got my CC from amazon.de with the S/N 4306... It came with firmware 15098, and I had to use regular_16664.hex to root it.
[Google Chromecast] Infected_Smile:
I'm currently in Japan and where can I get teensy here ?

Coz' no such device is found at local online shopping sites.

I really need that for my CC to remove regional restrictions. :D
[Google Chromecast] spec0071:
Hi,

I wanted to root my old and well used Chromescast, so got Teensy 2.0 ++, OTG cable and my pen drive.... and just realized that my serial number is starting from 3B04. Is there any chance to root it? Or is it still unrootable? Thanks is advance.
[Google Chromecast] bhiga:
Serial number is only a clue for what firmware build might be on new, unopened units.

Once it's been set up, serial number doesn't matter - firmware build does.

If it has build 19084 or newer, Hubcap won't work.

So if you have been using it actively, unless your Internet or WiFi connection is horrible it probably has already been updated to 20xxx or newer.
[Google Chromecast] spec0071:
Just checked mine, 26653. Anything can be done?

Can I downgrade it?
[Google Chromecast] bhiga:
Nope. Sorry. Can't flash without vulnerable bootloader (essentially root), so can't downgrade. Can't get vulnerable bootloader without vulnerable firmware.

You'll have to hope someone finds a new root method, though considering it was a year between the original 12072 exploit and HubCap, I really wouldn't hold my breath.

Buy a new Chromecast (and root it before setting it up!) and give your current one to a friend or relative who isn't interested in such rooty things.
[Google Chromecast] spec0071:
Thanks. So any new out of the box one will be OK for rooting? As long as I'm not updating it first?
[Google Chromecast] bhiga:
So far there have been no reports of new-in-box Chromecasts with firmware 19084 or newer, so you should be good, though it wouldn't hurt to look for the lowest convenient serial at the store. :)
[Google Chromecast] spec0071:
Thanks buddy, great help! :)
[Google Chromecast] techker:
hey guys i got a 383110 and i tried to get my tensy plus plus to recognize it and it never did??

so i tried a new version 422710 the tensy seen it,flashed it but when i got to the usb flash part it didn't do anything..even if i waited like 30min..
[Google Chromecast] shelby04861:
So. For those of us who. Didn't realize that the CC auto updates by itself, will there be any chance in the future once the SDK is out? Mine had the old firmware but I didn't realize that as soon as you connect it to the wifi network, it updates on its own. I thought there would be an option to say yes like everything else in the free world...lol. The reason I ask if there is still a chance, is because I want to know if I should still buy a USB powered otg cable, or just hold off until later.
[Google Chromecast] bhiga:
I've read a few "winks" at a possible alternative root after the SDK is released, but nothing in life is guaranteed, so unless you have another potential use for the powered USB OTG cable or find one on super sale, I'd hold off.
[Google Chromecast] shelby04861:
Good to hear. Just need more apps now ;)
[Google Chromecast] tomtuben:
3914 successfully rooted.
[Google Chromecast] jds580s:
I picked up a 3910 today from Best Buy and successfully rooted it.

I also have a 3930 still in the box which is going back thanks to this thread.
[Google Chromecast] bhiga:
Glad it was useful for you!

Filling some gaps while I still can...

Rooted 3912 and 3917
[Google Chromecast] wptski:
Just curious! You either have a big pocket of CC's or your rooting them for family and friends! :)
[Google Chromecast] bhiga:
Both actually. :)
[Google Chromecast] Dekan54:
Just an FYI.... I did some searching on eBay and asked the sellers to tell me the first 4 digits of the serial number. I have a 3828 on it's way to me right now.

Just another way to locate a rootable CC
[Google Chromecast] wptski:
That really doesn't mean anything if it's been used as it will have updated itself.
[Google Chromecast] bhiga:
Good idea. Just be very careful to check pictures - any peeling, wrinkles, or unevenness at the edges of the "Peel Here" label is a sign the unit was opened. The "Peel Here" label and leaves a faint "VOID" when removed, but that will be almost impossible to see without having the item in-hand.

Unfortunately some sellers like to list things as New when they are really Used but in very-much-like-new condition. When I sell stuff, if it's anything other than factory-sealed, it lists New (other) or Used. Also FWIW, eBay favors the buyer very much, "Not as described" still applies for the eBay Money Back Guarantee and is easily abused. I've already had it happen to me...

As someone else mentioned, Craigslist may be a better option if it's available in your area, as you can arrange to see the item before paying/buying.
[Google Chromecast] cordell12:
found a 3805 for sale at a undisclosed location ;) im assuming since 3804 and 3807 are "good to go" 3805 is as well :good:
[Google Chromecast] bhiga:
Yes, as long as it's fresh out of the box and hasn't been previously connected to the Internet, you should be good to go. Let us know either way.
[Google Chromecast] cordell12:
will do, gonna make one last effort of a local purchase from best buy, before i buy that one online. feel better knowing, than relying on someone i dont know trying to sell me something.

EDIT

found a 3910 at best buy, in fact they had about 10 of the "rootable' ones. Atascocita TX location.

EDIT 2

so got it rooted/flashed with KyoCast, now this is how Chromecast should work from the factory!
[Google Chromecast] efrant:
I just bought one here in Canada, and yes, the serial number is the same format. Mine is 3916101xxxxx.

As soon as I can I will try to get root.
[Google Chromecast] punkcell:
i just bought 1 from staples at first it looks like it said 3804 but now that i'm home its actually 3B04 does as anyone tired to root that kind before. if not i will simple bring it back and exchange.
[Google Chromecast] wptski:
Since 3A's won't and numerically 3B is higher, I'd guess that it wouldn't be rootable. You are the first that even mentioned a 3B.
[Google Chromecast] dmc2359:
Just got a 3910 from best buy at Cobb Place in Kennesaw GA. They had 2 rootables left, a 3912 and 3915 that I stuck in the back of the stack if anyone wants to grab them. ;)
[Google Chromecast] punkcell:
I bought it back to staples, they checked and didn't have any rootable 1's, so the guy said i can return now or after i try and root it :D

so i wil try tonight and let you all know, but not before going to bestbuy and trying my luck there.

Also, i see alot of 3824 on ebay.

but the person selling them is charging $35 + $15 shipping = $50
[Google Chromecast] wptski:
Lucky they still let you return it after trying to root.

After reading your post about the misread, I went back to Walmart which I had seen 3801 and 3804 or 3807. Guess what, they were all 3A or 3B! On some the "B" is a bit more defined.

I have two that are rooted but was looking for another for my nephew for Xmas.

If the 3B does root, please let us know.
[Google Chromecast] bhiga:
Did you try the other plusplus version? 3831 might have firmware older than 16664, but regardless, if you don't succeed with one version, it's worth trying the other.
[Google Chromecast] dying4004:
guys

i just bought a chromecast in australia

SN: 4711101RL8VQ

is it rootable?

cheers
[Google Chromecast] Srandista:
Connect it to WiFi with internet turn off, and you will see (by build version). Google probably still don't update FW in CC to newer version then 17977, but we don't know it for sure. These days, rootability is not determined by S/N, but with build version.
[Google Chromecast] dying4004:
How do I setup cc without Internet?

I tried to connect my iPhone to Cc's wireless and set it up, connect to my wifi with Internet turned off but at the last stage it shows check that your internet connection is working otherwise run the chromecast app to choose a different network

---------- Post added at 11:55 AM ---------- Previous post was at 11:09 AM ----------

This means, that your CC is already updated, and cannot be rooted with any of available method.
[Google Chromecast] esun:
I bought one from a Swedish retailer just now. Let's hope for the best!

Edit: Firmware version 15098. Ordered a Powered OTG cable for the installation.
[Google Chromecast] ReSkid:
Is FW version : 27946 Rootable?

Thanks.
[Google Chromecast] bhiga:
No. At the moment, 19084 and newer are NOT vulnerable to original exploit or HubCap, hence NOT rootable.
[Google Chromecast] ReSkid:
Ok, Does it depend on the Serial Numbers anymore? or does it depend on the Build number as someone said above.
[Google Chromecast] bhiga:
It has always been the firmware build. The serial number just provides guidance as to what build probably is on a

new, sealed, non-updated

unit, so you can guess as to whether it can be rooted. Once it is set up it will automatically update, so serial number is meaningless then.

Build number tells you whether the bootloader does not signature check (original exploit) or if it is vulnerable to HubCap exploit.

HubCap installs a no signature check bootloader.

Rooted ROMs preserve the no check bootloader by not accepting Google OTA updates (which would update the bootloader and lock you out).
[Google Chromecast] bhiga:
Okay folks, TOTALLY revamped the OP. Hopefully it's much easier to follow now.

Note that 4C10 (and newer, unless someone reports otherwise) is

not

rootable, at least by current means (FlashCast and HubCap)...

Hi!

I'm trying to root a new branded one (S/N 42251; F/W 15098) with a powered OTG and I always get the same error.

The chromecast logo, with a messaige that sais " chromecast.com/startup-issues

It cannot be roote via flashcast? I don't know where to buy a teensy in my country (Spain)so I tryed with otg powered.

Thanks!
[Google Chromecast] Srandista:
It's impossible to root CC just with OTG cable on any FW except 12072. If you have FW 15098, you need Teensy OR any cheep development board with ATmega 32u4 chip (for example from eBay).

I buy board from there as well, just prepare for long delivery, as it often goes from China or Hong Kong.

my chromecast serial number

Hello and tnx for detailed info

i couldnt find wether my chromecast is rootable or not

its serial number is : 3B2010XMU22 M:h2g2-42

its firmware version is : 12940

can u help me find out ?

and which method should i use if it is rootable ? is it going to work with flashcast ?
[Google Chromecast] bhiga:
You must use HubCap. FlashCast root only works on the original 12072 build. After you have root, you can use FlashCast to flash roms/mods if desired, but you can only use FlashCast to obtain root on units with the original 12072 firmware build.

Correct. Firmware build 19084 patched the HubCap exploit, so any Chromecast with build 19084 or higher, regardless of serial number, is not rootable.

Are you running two wireless APs on different subnets?

I had trouble with setup recently - had to disable automatic WiFi/mobile switchover and manually connect to the Chromecast's network (chromecastXXXX) before running the Chromecast app to set up.
[Google Chromecast] Segnale007:
Hello guys.

My ISP gave me a free chromecast and I would love to get it rooted.

I have read the FAQ but I am a bit confused about which rooting method I should go with.

Here attached is the screenshot with the build version and other information.

Thanks
[Google Chromecast] bhiga:
Your Chromecast has build 15098. Great!

Note that you will need a Teensy2 or Teensy2++ (there are also builds for similar devices, but you'll have to go through the thread), a 256MB (or larger USB stick), and a

powered

Micro USB OTG cable (or equivalent equipment).
[Google Chromecast] Segnale007:
Thanks for the help and clarification.

Unfortunately I think I will might have to give up at rooting it.

The cheapest Teensy2 I found is €27 + ships + €10 for the OTG..

I can't afford it atm, this is not the greatest period for me.

I'd buy a used one if someone here no longer needs it.

Thanks
