Any ideas how to mod / reflash a Google Jamboard device? - General Questions and Answers

I've recently acquired a used Google Jamboard (Smartboard TV thingie), and I wondered whether it could be reflashed with AndroidTV or similar, since as far as I found out, it's just a TV (and at 55" 4K a pretty good one) running Android and the Jamboard app. I haven't tried yet whether ADB is able to connect to it.. will do that soon-ish. I thought I'd check whether anyone else had tried that yet, but there doesn't seem to be anything around on the 'net. If I could turn that thing into a regular smart tv, that'd be fantastic.

If you flash anything, it would have to be built specifically for the model number of the device. What can and can't be flashed on any kind of android device is very dependent on exactly what hardware it is to be installed on. For example, all of the custom ROMs here for android phones, tablets, etc.. have all been built from the ground up specifically for the device it is being installed on, there really isn't a "one size fits all" android software option.

Very low cost tablet

Hi all, i'd like to buy a chinese android based tablet (price should be around 100€), i'd like to ask you which one do you suggest to buy.
I've seen one from my friend and i liked it, i didn't remember the model but i tought that the android market was not the official one, can it be? If so, there's any way i can install it? Or i can install other apps without the market?
Another question, are these upgradable? I thought that the Android inside the tablet was pretty old (1.6 maybe), this was not a problem in everyday use, but i'm a maniac and i like to have everything up to date, if i can.
Please let me know
Just bought the TechPad Android Tablet
I guess we'll see what can be done with these. I don't need an ereader so I am looking for this to be an extension of my android phone, GPS - browser - etc. I should receive it by the 9-25-10
It has OS 1.6 Android 7 Inch Tablet with a 800MHz processor, 256 MB of RAM, 1Gb ROM, WiFi, and the Google Android Marketplace.

Look at this: http://www.slatedroid.com/
There are many store where you can buy that table you can do your own research on the web so you can select the right store that will meet your budget.
@superchaos
so did you get the 7 inch techpad unit yet? if so how is it?
I did.
It is not replacing my phone, I seem to be able to see a lot of the apps in the market but I am unable to download them. It just gets stuck at the starting download screen. Wifi connects really well and has a great connection.
Some apps just won't install like google earth, Google sky map, Swype doesn't recognize the device, etc.
The touch screen is kind of weak and you really have to press to get it to get the typing to work. The system files are accessible and there is a "su" folder. I am not real good at getting into anything. It looks to me like it is rooted but I have not figured out how to get into a recovery mode.
I have tried to connect it to the SDK from google and it does not recognize the device. If anyone has any ideas, I am open to suggestions.
Market issue is likely just Google servers. Happens all the time.
You need to test root by running an app like titanium backup which needs root, and see if it works.
For recovery, you would only get a stock one, and I doubt you will get a custom one online if the device is not common.
Is USB debugging enabled for adb, and have you looked for it in device manager to see its hardware id and check if the id is listed in the adb driver list?
@superchaos
judging from the price the screen probably is not capacitive type but resistive. how's the battery holding? how long does it last before you have to recharge? does it look like it's upgradable to android 2.2?
thanks.

It doesn't seem to be rooted. To get the adb shell to recognize the device and to get Dalvik Debug Monitor to see the device, I followed the instructions here rbgrn.net/content/399-how-to-get-archos-5-internet-tablet-adb-working-on-x64-windows
I used HiDROID instead of Archos5 and the device id is USB\VID_18D1&PID_0002&MI_01
I run winXP not win7 and this worked. Screen capture works too. The programs I installed that require root just force close.

The screen could be a lot better. It is like there is a film on top of the screen for touch capabilities. The battery holds really well unless you are watching videos. 4-5 hours of constant use. You can leave it plugged in too. I am hoping it is upgradeable. The OS is built for a phone.
How do I get a list of hardware devices in the phone? Not just the specs on the pamphlet but actual hardware names/mfg's?

[CAR AUDIO] XTRONS TD620A - 6.2” Android HD w/ Multi-touch

Just bought and installed this 2-DIN headunit! So awesome to finally have Android in the dash. So far it seems great.
LIKES:
Multi-touch is a nice touch
Able to install my own apks without connecting to the Play Store
Finally get to use Live Wallpapers without worrying about battery drain
Customizability
Built in fan
DISLIKES:
Start up time kinda sucks
Wifi seems to trip out when downloading via phone tether
Ipod icon in the dock (how clueless is that?? Android and Apple aren't friends)
*Actually to be honest, I kinda understand it. A lot of people use their ipods/iphones to listen to their music. My major gripe about this though is that- I CAN'T GET RID OF IT! I don't want an Ipod app on my Android. I would like to figure out how to get rid of it. I'd much rather put my bluetooth icon in the doc.
So far I've installed Skype, Space Colony Live Wallpaper, Maps With Me, and RecForge Lite. I haven't tried TB or Root Explorer yet, as I don't have root access (yet!). It comes preinstalled with Gmail, Email, Angry Birds Rio, Radio (the FM Radio app), EZ File Explorer and several other apps. It runs really smooth for the most part.
Anyone else have this unit yet? Anyone tried rooting it yet? Please share your experience in this thread.
Just for reference, the stock system versions are as follows:
CPU Information
Freescale i.MX53
RAM Information
512M DDR3 800
Android Version
2.3.7
MCU Version
2.10.9-1-10-1
System Version
2.20.21
DVD Version
2.13.11-1200wb
What is interesting is I was able to access my root directory and files without rooting my device. However, when I checked with Root Checker Basic, it said my device was not rooted. And I'm unable to mount R/W. I was able to copy the system/app folder with no problem though. Is this typical of non-rooted devices?

So far I'm pretty happy with it. The start-up time is a little slow, but other than that, it does pretty much everything I want it to do. I was able to install a different launcher that's more customizable and more to my taste. I've been able to connect to internet and Gmail and the playstore without any problem. I haven't had any problem installing apps (except for when I was intentionally trying to install apps that I knew wouldn't work... ie. Samsung apps). No major complaints. Overall a great purchase!

When you say start up time, do you need to shut the device off when u leave the car, or can you put it in stand by mode?

Yup, it shuts down everytime you take the key out of the ignition. There is no standby or hibernate mode.
I just purchased this unit off Newegg and I'm really looking forward to seeing what it can do. I was curious if you ever got root access worked out? I would love to see this get some more attention from devs and really show what android in-dash is capable of!

Got mine installed few days ago. So far so good. Boot time is around 45sec, not a really big problem for me as i do drive more then one min every trip. The default audio player sucks. The unit always runs the default player automatically at the beginning. Every time you have to stop the music b4 you switch to other player. Kinda annoying.
question
I bought the same model XTRONS. I have a question I have downloaded the launcher? Is there any other Bluetooth dial? Because the original is dramatic.

Hi! I am used XTRONS model TDA-610A. The characteristics of 620 similar to 610. Then you can refer to the section "OUKU - Unbranded 6.2" 2 DIN Android Car Stereo Radio Head UNIT "These receivers are the same.
Hi
anyone manage to update firmware or root this unit? thinking of getting one.

[Completed] [Q] Problem with play market - your device isn't compatible with this version

I have a m8c eny tv android box with kitkat.
When i tried to search some apps I got
" your device isn't compatible with this version".
I tried to edit build.prop, but it didn't help.
What I can do?
Thanks in advance.
If your device truly isn't compatible there isn't really a great deal you can do other than to accept it. Be very careful about edging your build.prop too, editing incorrectly can cause the device to stop working completely so a lot of care must be taken.
Its very similar to other device em8 that works good with play market, so should be any way to do this.
Similar doesn't really mean anything, a petrol BMW and a diesel BMW are similar but that doesn't mean you can swap the fuels between the two vehicles. The same can be said for Android devices, being similar certainly doesn't mean they can run the same apps.

Shield Portable Marshmallow Options?

I see there are several custom marshmallow ROMs for the Nvidia Shield Portable. I'm thinking of upgrading as I'm sick of always having to move my apps around and not being able to update them. Adoptable storage solves that issue.
The ones I've found are:
CM: https://forum.xda-developers.com/nv...t/rom-cyanogenmod-12-shield-portable-t3042192
LineageOS: https://forum.xda-developers.com/nvidia-shield/development/rom-lineageos-shield-portable-t3562831
RR: https://forum.xda-developers.com/nvidia-shield/development/resurrection-remix-t3465740
Which of these is the most stable and supported? It appears CM or LineageOS.
Are any shield features supported on these? Such as (in order of importance):
Console mode
Controller
Gamestreaming (using official app, not moonlight)
Gamepad mapper
Thanks!
I'm running CM13 for the same reason, adoptable storage. Controller works but most shield specific stuff does not and other apps are needed. Let me know which one you end up on. Haven't booted mine for a while and thinking of wiping it again.
LineageOS is the continuation of CyanogenMod, I wouldn't use the cm builds anymore. And wow, somehow I missed RR getting released, need to go take a look at it sometime.
As for feature support (should apply to all custom ROMs, but I can't be 100% sure about RR):
Console mode: Yes, works fine.
Controller: Built-in works, wireless does not. Been working on the wireless support for years. I can make them pair and work, but there's no user friendly way to do so yet. See the end of the shield apps thread in the tablet section for more info.
Game stream official: No, does not work. As far as I can tell, support for the tegra 4 was completely removed from the M version of the shield hub streaming. As such, I cannot fix it. Moonlight does work, I am told. Don't use streaming myself as I don't have windows.
Gamepad mapper: This is virtually impossible to port from stock. Tincore is the alternative, but is a pain to set up.
Thanks for the informative response! Sounds like LineageOS is the way to go. If I decide I'm going to keep my portable I'll probably flash LineageOS (I'm debating selling it as I bought a GPD Win, but it's found a use as an Android TV system for my wife... so I'm debating keeping it or selling it and buying a cheap chinese system).
I've posted an atv build or two in my cm thread. Working on making atv work better in lineage right now. Been having troubles the last couple weeks, but have a couple more devs looking at the problems now. Once those settle down, I'll run another build for roth. It worked really well for the short time I had it installed. Might even end up my normal install once the kinks get worked out. But if you're interested in atv, I am working on it. If you want a really nice dedicated atv system, the shield android tv is amazing. For kodi, retroarch, etc, etc. A bit pricy, but totally worth it for the features.
Thanks, I'll look into it, but it's just a kitchen TV machine. All she really uses it for is CrunchyRoll and YouTube (hence why a cheap chinese system would be perfect).

Thank you for doing all this work! As you saw based on the other threads, I am using LineageOS now. I haven't fully tested everything yet, but so far things are mostly working well.

Xiaomi MI tv 4, 4a, 4c, 4s, 4 pro, 4a pro,.....

A common place to discuss and share for MI Tv.
Please share your comments regarding your MI tv.
And anyone succeeded in rooting or porting of custom rom or recovery?
Root can be done ( following a Russian site).

Anyone having the latest pro version of mi tv with Android 8.1?
A very useful tool which shows all the required information for identifying the correct firmware in case of something went wrong with the OS. So, keep in mind to place the screenshot of it somewhere safe. The app shows the detail of your display panel id, rom version, platform id...... All this is data is required before flashing a new rom as MiTv has so many many variant like MiTv 4a 49" has more than 4 variant, like wise for MiTv 4 55". So, on every model has some different variance, all because of having different display panels and for other reasons. Some display panel will be from LG or Samsung and two other brand from Chinese manufacturer.
Mi TV is a better option for limited budget. You will get more features for less budget.
If someone could share the rom and recovery dump file from the Mi Pro android 8.1 series, it will be a great help for the other previous Mi Tv users in porting the rom. Or at least share what you find for MiTv like rooting, custom recovery or anything for others.
Btw i found a way to root MiTv but its a long process and it needs UART device. And also to block the adds by using adb without root.
Again, so many MiTv owner pass by looking for some development for our Tv but find nothing mainly because no one is interested in so little interacted thread and not able to start any developments (at least in my view). Start sharing your experience, may be starting with your best optimal display setting.

First you need a UART device and then open the tv back panel and you have to make a connection at the diagnostic port on the motherboard directly.
If you are ready for this steps, prepare for the next move and let me know.

I do have the 43" global with build in Chromecast. Works nice and pic is also very good. No way to install Netflix for android tv and I cannot cast Netflix from my phone to the tv.. Everything else is castable.
Honestly I do have 43 inch 4A model. But the only concern here is do we need custom rom for this TV? I mean we already have one of the best stock firmware. Also, there is a way to sideload app from usb and once you install aptoide store then you can directly download apps from it. I have good amount of apps installed for me but few of them need mouse like Netflix and Amazon prime. Some of them need google play services so they do get installed but when you try go ahead they ask for play services. Also, regarding the UART port, opening the back panel will surely void the warranty, are people willing to go ahead with that?
I'm fond of mods and custom roms but here it is bit complicated as a TV is not a personal device which is used by only one person like a smartphone. I heard we will get the oreo update soon does any1 knows when it's scheduled?

Dear Friend,
I'm not concerned about custom ROMS here. But I want to enhance possible supported features in product not given by Mi.
I have Mitv 4a, and it doesn't support bluetooth speaker, while there is bluetooth in hardware. So by rooting and patching some firmware to make it working is my concern.
Another thing is, As phoneix rom and older Remix os were having support to replicate touch with Keyboard and mouse. If one can mimic that feature in patch ui firmaware than our MiTV will be more amazing:fingers-crossed:
I used to do same with Octopus app but its annoying for many apps.
Most important feature for me is supporting external sd card as internal storage. Which would not be possible without rooting MiTV.
What do you and others say about these?
I understand that you want to make optimum use of the hardware and explore all the possibilities. I personally feel it's a step we must take provided we have the source code and stock firmware readily available. Also, I have bought a wireless mouse and keyboard combo from Flipkart and it works like a charm. Regarding external hard drive support as internal, I feel the current version of android on MI TV 4A doesn't supports it natively. We should wait for the Oreo update and then should work towards it. Though my wife will kill me for messing up with the TV, I'm all in brother. It's just if anything goes wrong we should be able to put our **** together again
