Finally bought a G Tablet

Well I picked this up at Sears today for $380 with a mail i rebate for the docking station. I tried to update the firmware and kept getting a failure, talked to tech support and changed some settings. The update still failed and tech support suggested charging for 24 hours, they claim this will help. I have used the G Tab with stock software and it seems really fast. I won't download any apps until the software is updated, supposedly this update will fix some major bugs. I think I'm going to like this tablet once the someware is updated.
Regards!

Two suggestions:
1- Charge it (in that, I agree with customer service)
2- Update the stock firmware as soon as it's charge (not a mod, just a newer stock update). The reason why is that there are bugs in the original firmware where the system may freeze, which you want to avoid.
3- Wipe your user data. It really helps with a lot of user issues, like force closes.

Well I turned on my tablet tonight and it was ready to install the update and did it successfully. I can see the difference in performance already. I'm happy so far and how do you wipe the user data? Also another question about a game called bejeweled. I tried to download and the site was asking which device I was using to confirm compatability....viewsonic wasn't listed so I could not download so now what do I do?
Thanks!
Ed

Settings -- Security. I would recommend it, before you start installing apps - if you already have installed apps, then no harm no foul.

Ramos i9s tablet

My old faithful Archos 101 has serious problems and just bought Ramos i9s -> http://www.ramos-tablet.com/ramos-i...35f-quad-core-android-4-4-2gb-32gb-white.html
My version has 16GB memory and no 3G modem/sim-card socket.
Tried to find any info about this from xda, but not a single message found.. did i just order crap? :cyclops:

wow.. this must be rare tablet :laugh:

Not rare at all
Great tablet -heavy, but very classy design. It's a bit like a 9" iPhone 4s. Speedy intel chip. I have both the i9, i7, and i10 Pro. The last one is dual boot Android / Win 8.1.

Yep, this is heavy.. but I like heavy, better than feather-like
AnTuTu Benchmark scored 31472 and games looks awesome.
My first delivered tablet crashes after couple hours of use, maybe display cable disconnected or something.. because screen just went black and resetting/rebooting didn't never show anything else than backlight in screen. Got replacement unit next day and this one works fine.
There is one update from manufacturer downloaded, but previous unit crashed and that update might caused that also.. so waiting if others have problems with that update, before trying to install it again.

I have tried to find updates and root for this tablet, but seems there is nothing for this.
Manufacturer provides only chinese download page at http://ramos.com.cn/Download_list/List
I have tried to download from there, but after over 20 re-downloads.. all files seems to be broken and unusable.
Most likely my last china-cheap tablet ever. :/

Kingo ROOT works for root and is very straight forward. As far as updates go, I have not had any luck on that either.

Was able to find firmware download at Ramos site but was not able to download. When I click on download button it takes me to another page which tells me all about the firmware and how to install but does not give me a download option. The file is [i9s] Blue Devils i9s Le Frog OS stable version of firmware. Have any clues as to how to download this file? Part of the instructions is to install, ManufacturingFlashTool_Setup_6.0.43.exe. Do you know where I might get this file?

Just downloaded app, didn't read any intructions.. just installed app and hit Root-button, after some waiting got error message and rooting failed.
That Kingo Root needs windows application first.. right? and connecting to Ramos via usb-cable.. right?
I don't actually see any need for rooting this and after that, none of manufacturer upgrades probaply don't work here.. but.. it's hard to test, because they dont distribute upgrades. lol

Great device, How about battery life?

Thus far, the battery life has been very good.

New google Photo app crashes.
Somehow it almost starts if disconnected from internet, but asks google credentials and don't accept my correct account username and password.
If starting app when connected to internet.. Photo app crashes right after spinning Google logo.

General ROLL-UP -Joying 2GB - Sofia ( Non MTCB/MTCD )- Tips, tricks and mods

There is getting to be quite a bit of information to look through when looking for tip/solutions related to the new Joying 2GB / Sofia units. Since this is not a MTCB or MTCD unit, the threads seem to be scattered all over and very difficult to find in searching. I have seen roll-up threads for other units, that contain information such as ROMS available, tips, tricks and useful information. Kind of a "one stop shop" for the newer Joying HUs. If you have useful software, mod, tips, customization's, get something to work, etc please post here and I can include.
CPU Information - Rockchip Sofia x64 C3230RK / mali 450 GPU / Up to 1.2Ghz / 4 core / FYT5009 SoM - rated to run at up to 85C. My particular is unit clocked at 1.04Ghz.

https://forum.xda-developers.com/an...d-units/joying-intel-update-feb-22nd-t3561285
People have experienced issues with the Joying Launcher (UI3) after the update. This seems related to having other packages (google voice search ) installed prior to installing the ROM. Install time 25-35 minutes.
Recovery from non-bootable system - Without being able to access recovery, about the only solution is to reload the ROM package. Unzip ROM to SD card or USB stick, put in unit (GPS Maps slot, if using SD card ) and press the 'recessed' reset button. The unit should find the update and reload the ROM. This will wipe your data, but does leave the apps. If you use titanium backup, and have a backup, you can restore your data fairly easily. See blog article above for step by step instructions.
Root - Unit comes with root accessible in adb. SuperSU can be installed easily. There are 2 methods for installing superSU. The first method is an overwrite of the boot partition with a pre-rooted image. Problem here is if future upgrade makes boot partition changes, this method will overwrite with an older version. I recommend method 2, which modifies the existing boot partition ( need source so I can provide credit ).

https://drive.google.com/file/d/0B4qmTV7N4JliSjZMdGg3Z18wbkU/view?usp=sharing ( modifies existing boot partition )
OS & Google Apps - Android 5.1.1 ASOP based w/ pico installation of google applications. Voice actions are supported with installation of 'Google App' from play store. No support for google search talk back.
Recovery- A recovery partition is present but does not have any type of graphical UI. It does look like a complete stock android ( command line ) recovery, but no access using USB is available. It maybe be possible using PC-PC OTG cable.
SD Cards - I have not heard of any sdcard size limitations, up to 200GB have been reported to work. Must be formatted as FAT32. NTFS, exFAT, and ext3/4 do not work. You can format a USB stick with ext4 and it will work fine.
Google Voice Calling - Stock BT dialer crashes when being called from google applications ( such as google voice search ). Workaround is available.

Apps not working after resume - The joying code will kill most applications when going into standby. This is really bad for apps that are supposed to be run at boot and background process, as they are not restarted when exiting standby. Symptoms include, widgets not updating, apps not getting GPS lock, process show running but background services are no longer running. This can be fixed by installing an updated apk file in /system/app/Sofia-1-C9-Server-V1.0 which removes the task killer. Also the key/button mods V2+ (below) will remove the task killer.

Yes this is really needed. A FAQ with overview links and tips in just one post

Some people mentioned it was possible to boot into a restore function from a memory card with the update zip. If true, do we know what the exact process is? Any keys need to be held down?
Update, verified this procedure works:
sonof said:
I did recover from endless Android logo (resulting from trying to root with Joying HU root.zip found in this thread).
I did the following:
Put latest Joying update files to microSD card and insert it to GPS slot. Press and hold both reset and power buttons. Once it boots continue holding reset button.
This lead to automatic install of Joying update files and my HU was back alive but I hate the Joying company for not providing means to enter recovery and a complete ROM.
Edit: For me it did not ask if I want to update or not. It just began updating automatically. In contradict to the post above. But I was unable to boot to Android when I tried this.

My VW has reverse parking sensors. Does it not support those?

Just installed this unit. Speedwise it's night and day compared to my old Erisin (1gb 3188). Display is nice and crisp. Bit of a fiddle getting it mounted because of all the crap that needs to be stuffed behind it, but after some swearing and elbow grease I got it secured.
From the instructions, I cut an orange wire because I don't have a backup camera. I do however have optical parking sensors. On my Erisin this was supported (it showed a car model and visual indicators on screen). This unit doesn't appear to have this function. Can anyone confirm? I still get the beep from the speakers, so it's not really a big issue, but would be nice to know.

Didn't see your post before asking the same question

anotheruserx said:
I'd like to work on this one.
But I have two questions;
1) did you manage to get any logs of how it failed?
2) When you made it unbootable, what was the exact procedure you used to recover the unit?
Click to expand...
Click to collapse
I didn't get any logs, as I couldn't connect to it until I reloaded the ROM. If I was able to make a USB connection, at least I could have looked at the logcat.
Procedure to recover: Insert USB drive with ROM, push recessed reset button, wait 30m for ROM to install, set up apps again. I have this procedure down pretty good. - The joys of playing with the system partition without USB access or recovery tools.

Actually, it turns out it does, however only when there's an obstacle (hopefully we can change this). Yesterday I only tested while stationary. Today I used it while driving, and noticed that whenever the sensor picked something up, the unit does actually display the sensors. It feels next to useless for me when it only shows on beeps, but at least we know it's there.

Well, that is the way my discarded Newsmy worked. Takes getting used to, but you then again you don't really need confirmation that "nothing" is in your way
Will need to think about this then, thank you.. Cant make up if I want this or the Ownice C500.

After updating to the January firmware parking sensors are gone completely.
edit: enabling "radar" is the solution

Installed supersu (like described in this thread) yesterday and updated it from the play store. Worked fine.
Then I installed Viper4android, also from the store. I didn't expect it to work, but it does! Driver installed, and after a reboot it does exactly what it's supposed to.
Also installed Nova Launcher and set as default home. No issues with that so far. I have not frozen or uninstalled any of the original launchers.

On my Joying unit 130N2 (8 inch unit for VW) the backlight on the display does not work when it is cold. We had minus 8 degrees centigrade here and it took more than 10 minutes before the backlight came on. The radio is playing music and it is actually possible to change channel as long as you know where to touch the monitor. Today it was 5 degrees and it took only about 3 seconds before the backlight came on. I wrote Joying about it and they confirmed to me that there was an issue with 8 inch models for VW. They told me that they were working on a completely new firmware that would fix the problem. I told them that to me it seemed to be a hardware problem and how they wanted to fix that with a software. Their answer of course "No worry my friend ......". I told them that I wanted to return the radio because a radio that doesn't work when it is cold is useless to me. They told me that I would have to send it to China so that their engineers could investigate the problem. I then told them that I had bought it from a German website and it was delivered to me from Germany so if their wanted it to be sent to China then they would have to pay me for it - in advance. They told me that their warehouse in Germany did not accept any returns so it was impossible for me to return it. Then I opened a case with Paypal for selling defective merchandise. Then suddenly their warehouse in Germany was accepting returns. I had put this text also on the Joying Forum, but of course they deleted it. So when dealing with Joying and in case you have problems my advice is to be very tough on them otherwise they will BS you.

I have the same problem on the same unit. With the car headlights off, backlight is dim when it's cold, but gets brighter when it has time to warm up. And when the headlights are on, the backlight isn't on at all until it warms up.
I thought about writing Joying about it but I expected the kind of response you got. Plus, I've had my unit for a few months already so a PayPal claim isn't an option. Please let us know if you hear anything else about it from Joying.

Hi Joshnat,
Yes we have the same problem. Sometimes I can get mine to light up by turning the headlights on and off a couple of times. Are you sure that you cant make a Paypal claim? As far as I know you have 180 days.
Anyway, you should write to them and let them know that you know that many others have this problem.
Regards
Kurt

You may have a faulty screen, my first one did something similar and wasn't very responsive to touches. I returned and my second unit was like night and day with how much better it looked and worked.

Has anyone got a factory backup camera to work? I have a 2015 Camry and right now I have the older Pumpkin rk3066 and the place that installed it hooked up the factory backup camera. I got my new Joying hu yesterday and am going to install tomorrow myself. I'm really hoping I can use my factory camera with this head unit also.

I have the same car and HU, my oem backup carmera works. I bought a harness on Amazon including backup camera, USB, and aux in.
https://www.amazon.com/gp/product/B01BM3QGCO/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1

Quick tip:
You can adjust backup camera brightness, saturation and contrast by touching the screen while backup camera is on.

Is there a trick to putting in the sd cards? Mine won't click in so it won't mount.
Edit: Forget it i just had to get the edge of a screwdriver and push it in. Had me worried for a minute.

Within the zip there is a file with instructions - HOWTO.txt
How-To install:
1. You need a Windows PC that is connected to the same WiFi network as your HU.
2. Unzip the attached file somewhere to your disk.
3. Run CMD.exe as Administrator
4. Change directory to the folder that you unzipped.
5. Run the install.bat script with an IP address of your HU as a parameter:
C:\Users\<username>\Downloads\Joying_JY-UL135N2_SuperSU> install.bat 192.168.123.137
6. Wait until script finishes and reboot your Head Unit.
7. DONE!
You should now have the SuperSU application working.

Hizpo Head unit with inverted screen

Hello everyone. I’ve got a hizpo stereo that a friend of mine give me a few weeks back. The numbers on the side of the radio is ADY17009. It’s running Android 7.1.2. The problem I’m having with it is the screen is inverted. I’ve tried the reset button tried erasing everything no luck. I tried accessing developer mode pressing build number 7 times and it didn’t let me access it. Anyone know where I can get a copy of the stock firmware and operating system on this thing or can I upgrade it to the latest and hopefully it will fix the issue. I can’t sign up on hizpo website. Every time I try to I get a connection timed out error. I had posted in the general forum so please delete that. That’s what I get for not reading lol.

This is usually a symptom of a loose connection in the hardware(believe it or not, a good shake, tap or bump this way or that way has been known to solve this) or a symptom of the sensor needing to be recalibrated(also solved by shaking/bumping or even lightly dropping on a soft surface from about 12 inches, but doing it while the device is powered off)
Or, if the device still functions correctly, there are apps that can recalibrate the sensors for you.
As for finding the stock firmware...
If a Google search for:
"Return to stock (your model number)"
Is not finding anything, then it probably isn't available. These cheap, off brand devices usually do not get any software support of any kind from the manufacturers, they do not release the stock source or the stock firmware to the public.
If it came down to really needing to flash the device, you'd have to look for a firmware from a device that uses the exact same hardware as the device you own. That can be very difficult, it requires opening the device to look at the numbers on the hardware components, then using those to compare to other devices. If one of those devices is the same as yours and has a firmware available, you can use it.

Dasaita PX6 SD unmounted on every boot

I've got a PX6 unit running the latest firmware from Dasaita: HA3_rk3399_10.0_ota(20210311). It's rooted but otherwise stock. I'm running Car Launcher Pro as my launcher, and Poweramp as my music player. My SD card is a Samsung Evo Plus 128GB formatted to FAT32.
After a warm boot, the SD card is not mounted, causing Poweramp to lose all its music. To get it back I have to physically eject the SD card and re-insert it, which is incredibly annoying at the start of every journey.
I have contacted Dasaita but have not yet received a reply.
Does anyone know how to fix this?

I have the PX6 unit running the latest MCU, but only Android 9 ROM (none of the downloaded Android 10 ROMs seem to work) and I have a similar issue with my USB1 not being read always. But USB2 or 3 is always available Would love to know where you got a working ROM? The one from Dasaita website will not load.

You are not missing anything running Android 10.
The most stable working version I believe is 8, all versions post 8 are rushed ported bug fests.

I've got a PX6 unit running the latest firmware from Dasaita: HA3_rk3399_10.0_ota(20210311). It's rooted but otherwise stock. I'm running Car Launcher Pro as my launcher, and Poweramp as my music player. My SD card is a Samsung Evo Plus 128GB formatted to FAT32.
After a warm boot, the SD card is not mounted, causing Poweramp to lose all its music. To get it back I have to physically eject the SD card and re-insert it, which is incredibly annoying at the start of every journey.
I have contacted Dasaita but have not yet received a reply.
Does anyone know how to fix this?

My suggestion is to copy the music (some or as much of it as you can get) from the SD card to the internal memory and set that folder as the primary folder for PowerAmp. These units seem to have more difficulty mounting SD cards, especially higher capacity ones.
I've had a little better luck with having fewer folders with more files than the other way round. By at least having some music files in the head unit storage, this should get PowerAmp playing music sooner and it should catalog the files on the SD as needed in the background once the SD card is mounted.

I've been kind of torn between using the "warm boot/auto sleep" capability vs just having the head unit shut down every time. It seems the "auto sleep" function never brings the head unit back up the way it was when the car was turned off.
Since the cold boot time is so "short" (I use that word rather loosely here) it's probably just as well to let the unit shut down after n minutes/seconds. Like what's the use if the "fast warm boot" requires us to have to fiddle with stuff every time (e.g. popping SD card out/in, etc)?

You are not missing anything running Android 10.
The most stable working version I believe is 8, all versions post 8 are rushed ported bug fests.

I appreciate your input! I am not "chasing a higher number", I am just trying to realize the features that were supposed to be in the product I purchased, such as split screens, 1280x1024 resolution and Android 10. Instead I got 1024x600 and Android 9 and very unstable. Navigation link fails to launch Wayze or Google Maps, VLC cannot display any video , they play but there is no video (audio sounds great) and an awful looking radio app.
I hear great things about the stability of the PX6 Android 9 version rk3399-userdebug 9 PQ2A.190305.002 20191210.152625 test keys. Supposed to be VERY stable and fast. Anyone have this version?

Sadly was an eBay purchase that was "NEW IN BOX", but according to the stickers was an Amazon return.. All packing was perfect, I suspect that the purchaser got the wrong unit for his A/C controls.
Dasaita model is HA-5226-MAX6-CP, also shows X002F1YJQ9.
Instructions were clear, all components were still factory packaged, I just want a stable usable preferably factory (unmodified) ROM.
And I'd be happy if I could find a stable A9 ROM. Two weeks of searching and enough is enough.

Mine came with 10, I just updated it to a slightly newer version. Was really hoping not to use internal memory as its a pain copying stuff over when you want to chop & change music around, vs just bringing the car inside and doing it on the computer, especially as updates tend to wipe the internal memory, or require a factory reset (which doesn't preserve userdata on these units)
Will try the cold boot and see if I can live with that, otherwise it may be back to Malaysk ROM (which worked great on my PX5). Anyone know if the issue is resolved on that ROM?
I'm also annoyed that it was sold as supporting bluetooth tethering, but does not actually do so, but turning that option on is what killed my PX5, so I'm reluctant to mess with that.

Just seen that a new firmware is out, so might try that.
UPDATE2: Ignore below. Firmware update didn't fix it.
UPDATE:
Firmware HA3_rk3399_10.0_ota(20210507)升级包 seems to have solved it, and also solved the issue where Car Launcher wasn't updating track names and album art reliably.
I'll confirm tomorrow when the radio has had more time to idle, but I think this is the fix!
As a bonus, I was able to dirty flash without issue. Had to re-root but that's to be expected.
I first updated the MCU to 3.75B and that did not fix it, so an MCU update probably isn't necessary.
