Trying to Identify Kernel, Possible Overclocking Possibilities for DM7022 Radio
- Thread starter rvcullen
- Start date
It does have a accelerometer but the bluetooth is built into the mainunit not the PAD unit so you can only use bluetooth phone function with the vehicle and any bluetooth app from the pad market itself does not work
So I guess you don't want me to upload those recovery files then. Does anyone know if you switch to the bare 2.2 rom if you lose the functionality with the main unit like playing dvds and what not.
Thanks P.S. I don't know where you would want me to upload them to because they are too large to upload to the forum if you still want me to upload them.
Also I have cleared the cache on the market and did a factory reset and still no luck with the market working I tried downloading a new market apk but it just said unable to parse the package not sure what to do I really don't want to send anything back to the factory for fear of never seeing it again.

Hi wuoma,
Welcome to what feels like the only place in the world where you'll find answer regarding these devices. I and the others will try and help as much as we can.
In fact it looks like you've had a few answers already but let me just add my oar in...
- Does the tab part have all the acceleration sensors in it (i.e. does it rotate the screen when turned on its side) ?
Yes, the pad does have an accelerometer fitted and it works very well. It's very rare for my ES777A to get confused when swapping between orientations. - Does the Android OS recognize the bluetooth device when the tab is connected to the car radio part? What I mean by this is can I use BT in android when it's docked?
No, unfortunately not. I've found no way to interrogate the car unit’s hardware when the pad is connected. - Does the Android OS see the DVD disc or SD card that are in the radio part? I understood that this does not have the dual zone functionality that I could listen to the car radio part while navigating in the Android OS part, but I think I should be able to have a media player program running in the background playing music in the Android OS while navigating say in Google maps?
Again afraid not, The DVD and SD card within the main unit is not viable to the the PAD. that said the good news is you can have the radio playing whilst using the navigation on the pad. Although in my experience this isn’t perfect. It stutters a lot and becomes a little annoying after a while. Guess it depends on whether your navigating around somewhere with lots of turns or speed cameras (e.g. the more voice statements from the pad the worst it gets).
A couple of words of warning if your using the Bluetooth to make a phone call don’t switch to the pad during the call (say to make a note of something) it drops the audio (not the call just the audio) leaving the person on the other end normally shouting "hello... Err Hello!!!”. Swapping back to main unit reestablishes the BT call without an issue. In terms of having the audio from the pad and the sat nav on at the same time; yes this isn’t an issue. - I'm hoping to use this as an all-around Android device in my car - using OBD connection to view live data from the car using Torque or similar software in Android, as well as getting performance data using the GPS and acceleration sensors. And finally getting Spotify in my car, I've payed for the premium deal that allows Android devices to cache offline versions of the songs so I'm hoping to use that here as well!
Well you want what most of us wanted from this and the older pad/unit and I think together we could all get there but for the moment it is an uphill struggle. Given Bluetooth isn’t available via the pad your only option for OBD connection would be WIFI but before you rush out and buy one (like I did today) you need to be warned the AD-Hoc connection aren’t enabled within Android by default. Normally it’s just a case of swapping /system/bin/wpa_supplicant out for a modified one (you'd need root but that’s relative easy to get) but so far I've only had limited success. Most, if not all wpa_supplicant I've tried so far find the AD-Hoc WIFI but fail to get an IP address. I've pushed the IP out manually and on some wpa_supplicant I can get a successful connection but I've not actually been able to connect to services on the remote end. I only ordered my ODB2 WIFI adapter today so won’t be able to fully test AD-Hoc until it arrives. I'm hoping that it’s my old laptop that’s actually causing the Ad-hoc connect to fail (wouldn’t be the first time) currently but time will tell on that one. As for your other aims GPS, acceleration & Spotify I can’t see that being a problem. Have a look at some of the old post here you should get a rough idea on how to do most things you want / will need to do. I'll keep the thread updated about the AD-Hoc WIFI test later in the week.
So welcome to the group and I hope you’re happy with your unit when it turns up. I know despite my initial problems I'm happy with my one.
Gareth
Ps. forgot to say don't spend ages trying to get a GPS signal on the pad when it's not in the main unit. As gps chip is on the main unit not within the pad.

This is the bare rom that I was wondering if you lose the functionality of the main unit like watching dvd's or if that stuff still works.
Thanks in advance

hi ktxnrdki012,
I can't see the picture your included but I'd guess that su has lost its permissions or you might have a bad symbolic link.
what happens when you try and connect manually via adb?
open a command prompt as an administrator
cd to your Superoneclick directory
then change to ADB directory within Superoneclick folder.
type and run
adb connect localhost:5037
type and run
adb devices
This should show your pad is connected. If it isn’t make sure you still have usb debug mode enabled on the pad
now try adb shell
you should end up at a command prompt looking like "$" or maybe even "#".
either way try running this command
ls -l /system/bin/su
and
ls -l /system/xbin/su
and let us know the results of each.
If you know all this already then apologies, just trying to save time by pre-empting the next question.

Thanks for the welcome and the answers
It really does seem like there is absolutely no talk about these devices anywhere else, which seems strange since they have already updated the version and made improvements so it's a bit better than most of the most generic Shenzen tablets.And to answer your question - sure, I'll make a recovery image as soon as I get the device. Just ordered it yesterday and they had sent me an email confirming the parcel has been sent during the night.
The Bluetooth issue is a bit of a dissapointment, maybe I'll look into getting a USB BT dongle working. Depends on whether the drivers are already there or not. By the way, there are also OBD plugs that work in infrastructure mode so you won't have to mess around with the ad-hoc settings.
Here is one such example: OBDKey :: OBD WiFi :: OBD WLAN :: OBD Wireless LanHowever I'd much rather have a working BT on the pad so that I think will be my first priority when getting this.
By the way, has anyone opened the pad yet to see what it has on the insides (perhaps more usb ports or something)? Maybe a bt adapter could be put in there... I had a cheap Shenzen android pad last christmas and there was a HUGE amount of space on the inside of the shell and some unused ports as well.

Hi
I know somebody opened their ES666a unit the other day as the transflash had fallen inside it but I cant remember who, (afraid you'll need to look back on this thread to find out. I'm meant to be going out to brave the UK sales and Im already late.) It's actually very easy to miss the card slot and push the transflash behind the holder and into the pad even on the ES777A.
Thanks for the link. I didnt know they did non adhoc version WIFI version. Although using the OBD module is something thats relatively new to me but the extra cost looks to exclude it as an option for me.
Oh, and cheers. if you could sort the recovery.img for me I'd appreciate it.
Gareth
I did the posted framework.jar which INDEED fixed the gps speed error issue so thank you very much. the oneclickroot doesn't work on the es666a, it just keep saying that its already rooted and when tried to root again, doesn't work. So what i did was download Z4root and apply Temporary root", the permanent root doesn't work but temp root works til next reboot but thats all i needed always. temp root and down root explorer, navigate to system/framwork, rename framework.jar as framework.jar.bak as instruction stated previously but make sure you mount it as R/W in root explorer. also i needed to delete some files in order to move the new framework.jar into the system file. i just deleted all my ringtones, alarms, leaving just one of each and delete some unused system apps like the eoemarket. mount back as R/O and reboot. it should work and it worked for me

I had my flash card fall inside
. I am also working on the adhoc thing for my OBDII-Wifi adapter.Similar threads
