[Q] "A9 NEC RENESAS EMMA V2 Dual Core Android 2.2 Tablet" review anyone?

Hi guys!
Since I didn't find any review to the "A9 NEC RENESAS EMMA V2 Dual Core Android 2.2 Tablet" offered in the (german) cect-shop, I was wondering whether someone already bought and tried it. Specs are quite nice, IMHO and videos on youtube look promising. Can someone share his experience with that tablet?
Thanks in advance.

Hi,
I personally have the device and the experience so far has been good using the device.
There is a whole bunch of information over at slatedroid page where there is a group of active users.
Sorry but my post is very little so you have to head over at slatedroidpage, please replace the dots with "."
www dot statedroid dot com/forum/204-rena/
Perhaps someone wants to start a thread over at this page? Hopefully some XDA developer over here owns the device and we can get things started
overall the device has received 3 firmware upgrades so far and the community is hopeful for gingerbread to be released for this. We do have the kernel source codes for this product but do not have any developers to help us out with getting gingerbread out yet for this.

also replace statedroid with "slatedroid"

I also don't purchase this tablet, but i purchase flytouch 3 from a china site,called mcbub.com,i find they have the A9 NEC renesas tablet, here is some review in their site:
http://www.mcbub.com/customer-revie...GB-Bluetooth-HDMI-MID-black-CN101769--136318/
hope this can help you.

There are a lot of discussions on A9 NEC RENESAS EMMA V2 Dual Core Android 2.2 Tablet at tabletrepublic forum too http://tabletrepublic.com/forum/cortex-a9-renesas-ev2/

full root for Rena 3
Greetings, comrades!
All the usual, lazy engine of progress. Tired of doing manually as rooting and rebuild the firmware for Rena, i am wrote a script that works like a flash, but flash itself is not working, just do it root! =)
Thus, the universal root for any firmware Rena 3:
Install:
Unzip all the files and qroot directory to root SD card.
Turn off the device.
Turn on, hold VOL+ POWER.
Wait until the message "Well done. Root complete."
Reboot device, enjoy.
The necessary files and directories:
install.sh
uImage4
ff4
cramfs4
sdboot.bin
uboot-sd.bin
and directory /qroot
NOTE!
The update does not repartition and reformat the partitions do not.

[Q] Acer Liquid S1

Hi all,
Since there is still no device specific forum for the Acer Liquid S1.
Me and probably many other people who own this budget 5.7" phablet beast consider this phone as a device that certainly deserves his own forum
Until there is a device specific forum I created this thread so every S1 owner can share tips and questions regarding the Acer Liquid S1 (=S510).
I didn't see any request for a device specific forum, so make sure to request it here:

Haven't seen anyone try it yet - but I'd guess it's done through the standard MTK-procedures? http://forum.xda-developers.com/showthread.php?t=2160490
Possibly even motochopper that works for the Liquid E2? http://forum.xda-developers.com/showthread.php?p=40747604

Hope there will be some dev around this phone too

Agreed and now looking at the details of new Acer Liquid S2 - I feel it definitely deserves it's own section - especially when I compare the specs to the likes of Ultra and Note III a worthy competitor and would like to see some development and discussion on this model.
ps: added a request to create forum - in the new devices section - hope someone does create one and we can see some new development on this

Trying to root it, but this device seems to be well locked. :/

Thats bad news, this is what is holding me off getting it at the moment. I did find a link when searching for a solution that led here :http://pan.baidu.com/share/link?shareid=2798984876&uk=2318828147 (it is in chinese).
Don't know if it works though, been searching for confirmation of the device rooted but with no luck though.

Thats a shame.
The main reason I need to root initially, is to be able to transfer my files from existing phone. Does anyone know if Helium would enable this ?
If this works, then I don't mind going for this phone, and as long as I can transfer my data, I can hold out for root until hopefully more developers get on board.

Helium could be enough yes. What files exactly do you need to transfer?
Envoyé depuis mon S510

Mainly my game files, well Subway surfers for definite. My apps I can download again from the play store. Of course some games are now connected via G+ sign in, so they are alright, it is just a shame that this feature isn't compulsory on all apps/games. It would make the transition to a new phone easier.

The camera is just of average
Just bought Acer Liquid S1 a couple of weeks ago. Everything works fine except for the camera. With 8MP camera fitted on it, the quality of the picture is just mediocre. The front camera (2MP) is also disappointing, full of noise when it is used indoors. There's no visible notification when the display is off. Therefore, we need to turn on the display to check whether there's a miscall or incoming email or text message.
Is there any way in which I can have root access for this phablet? I have ODIN software installed in my laptop, and I just need a *.tar file special for this product to root it.

Just moved over from Samsung Note to this phone as it's Dual Sim. Brilliant, as I no longer have to carry two phones with me. Works great. and less than half the price of a Note. I miss the stylus, but apparently a dual sim Note may be coming soon!

Hi that's strange as the app that flashes will check the ROM version and won't flash if your system is not as expected. Did you use the app ?

[Completed] Android tablet won't download+ other problems

I've got an Android tablet that I cannot download anything to.
Tried a hardset restore a few times that didn't help.
I think something or things got force deleted by mistake.
It's a Chinese generic tablet. I could send it back for refund but cost $50.
The tablet cost $70 so that don't work to well.
Here is what I know about the tablet. I would like to revive it if possible.
I'd try most anthing because it's not any good the way it is.
Some firmware for it might help if I could find it. When I try to download I get a message "Google play is missing from my tablet.

Hi johnsonxxzz
Thank you for using XDA Assist

Intel Atom x86 SOC, how hard is it to load rom from a different atom z25xx device?

I am on a Asus trio tx201la INTEL x86 tablet on android 4.2 on the tablet part. I researched that The zenfone 5, dell venue 7 and the samsung galaxy tab 3 10.1. All have the same intel atom z2560 cpu soc and some are running Android 7 & even 8 now.
The Galaxy tab 3, zenphone 5 got a lot more attention and thus a lot more custom rom attention. Dell venue and my Trio got little to no attention due to poorer sales.
The galaxy tab 3 has been updated to 7.1.1 see:
http://techbeasts.com/install-android-711-nougat-galaxy-tab-3-101-lineageos-141/
Now How can that help the Trio? I found this tool, but no flash.xml so no luck using it:
https://01.org/android-ia/downloads/intel-platform-flash-tool-lite
Here is a guide on how to use it: http://www.aryk.tech/2016/04/how-to-flash-stock-firmware-using-intel.html?m=0
This is all NEW as of 2017. So its not been available before this.
The TX201LAF a french tablet version of the TX201LA is in the same boat but it at least it is on 4.4. Its kernel firmware is here: http://support.asus.com.cn/Download.aspx?SLanguage=en&m=TX201LAF&p=3&s=587
My big question is with all these roms for x86 atom z2560 & z2580 soc's shouldn't I be able to get an updated rom somehow? I imagine that would involve building a rom myself but if the base soc is the same isnt it possible to build the rom for a different device and use a different kernel source like I linked above? The kernel source has the drivers I need right, for the device to run? Ive heard a lot of people talk about you wont get the touch panel to work or the wifi. I understand that but isnt it all loaded from the kernel source? So basically if I have kernel source and grab an updated rom from lineage 7 for the galaxy tab 10.1 and replace the kernal i'm good to go right? I know there is more to it but really looking for some help here?
Even if I can just get the tx201laf image to load on my tx201la that would be
something, its an update from 4.2 to 4.4. Both devices are identical, so that should make it a lot easier right? Looking for any insight to xda experts can provide.

Hi ! I'm still using my trio so I'm very interested ! Did you succeed ?
Thks a lot

no luck yet
I had hopes that this would turn out to work but you cant use the intel flash tool without a flash.xml which is written for the device. SO that stopped me dead in my tracks.
I recently found this: https://forum.xda-developers.com/android/software-hacking/efidroid-t3447466/page37
Hoping this dev will give the tx201la a shot. There is also this: https://forum.xda-developers.com/an...g/tool-multirom-recovery-replacement-t3102395
Do you realize how simular the tx201la is to just about every zenphone made since the newest. IE almost all of those roms would likely boot on our tablet.

??

Any other input?

Come on guys, has everyone moved on to the shinny new toys?

Anyway that lead me to this: https://cs5-3.4pda.to/10031052/20170404_145326.jpg?6c8bd0e99d5f5d5ce8c14e92c456565c
That might not mean much to many but its the TX201LA running the Asus memopad 10 android 4.2.2 and its actually working. So that is a huge deal.
Then I found this: https://forum.xda-developers.com/an.../rom-8-0-0-lineageos-15-0-unofficial-t3693838
There is a updated rom for the memopad 10. Now I hope I can get this rom to run with slight variations.. Will see..

Mediatek MT8173 & MT8176 Development

Mediatek MT8173 & MT8176 development
Hi folks, after I've long been working on my device and only made little progress in building LineageOS for my Xiaomi Mi Pad 3 I decided to look for other developers with similar devices.
My Mi Pad 3 (codename: cappu) is a tablet based on a Mediatek MT8176 SoC. It was launched in April 2017. The tablet comes with a 7.9" display with a resolution of 2048 pixels by 1536 pixels at a PPI of 326 pixels per inch. It is powered by a 2.1GHz/1.7GHz Hexa Core processor ( 2 x 2.1GHz Cortex A72 + 4 x 1.7GHz Cortex A53 ) and it comes with 4GB of RAM. The tablet packs 64GB of internal storage that cannot be expanded. It was shipped out with Android 7.0 (Miui) and is still on this version).
Two months ago Xiaomi finally released Kernel Source Code for my device. It was broken, but I fixed most of the conflicts, streamed the kernel up to latest linux-stable and added some features. I also tried to build LineageOS & AOSP trees, but I have to admit, I'm starting to get desperate. For this specific SoC - even it's predecessor MT8173 - there is no activie development. And that is what I am looking for!
I collected some devices that either use MT8176 SoC, or the older MT8173 SoC. Some of them have Kernel Sources, which I listed and linked below.
All questions, requests for help, suggestions, ... are welcome. If you own any of the listed devices feel free to write and help. This thread is also on Reddit.

First thanks for your initiative! And I am very interested in obtaining a Custom ROM for my Teclast T10 E3C5 device with the aforementioned MTK8176 Chipset. I cannot help you with development but are open to test it and report bugs.

Hi Goayandi,
I'm not sure how many experienced ROM developers you will get. (I'm not one of them. I have compiled and modded existing ROMs, but never ported one.) I've heard several people say they will look into building a custom ROM for mt8163 or mt8173. But that's always as far as it gets. They never come back with any results. So I was just curious, what are you getting stuck on?
As far as I can tell, one major problem with porting to Mediatek is that they modify a lot of Google's OS code like frameworks and libraries. I do see that you already have some MTK customized repositories in your github library. You may have to do some reverse engineering of the stock ROM to confirm that the MTK changes are the same ones you have in your repos. Yes, that's a huge pain. It's also likely that MTK's patches for mt81xx and mt67xx, which is probably what you have, are pretty different.
One suggestion I want to make is to start out with a ROM that's as close to stock as possible. That means building a plain AOSP build NRD90M. This will reduce as many trouble-causing variables as possible. That's how I would do it. If you accomplish that, it will be easy to move on to higher Android versions or LineageOS, etc.
I would also use the prebuilt kernel for now. There is not much point to compiling your own for the same reason I just mentioned. A lot more variables would enter the equation. (Unless maybe you can test it independently with the stock FW.)

Any chances of giving TeamMAD access to one of these devices?

I have a Teclast T8 stuck in fastboot mode. No recovery, no system. adb cannot see the device. Is there a way to recover from that?

I tried that. That would work if recovery were bootlooping, and system were intact. In my case, my T8 cannot get to system. The Teclast Logo goes through its animation on startup, then gets stuck there. Holding volume up and power gives me 3 choices: recovery, fastboot, normal. Recovery and Normal are both broken. Fastboot is the only one I can do. How to recover from that?

You need to reflash firmware/rom with the sp flash tool.

You should flash stock firmware on your tablet with SPflash tools. Search for Mediatek SPflash + your device name in Google. Flash procedure should look like this:
FLASH Mediatek device
- Unpack FlashTools, and Click on Flash_tool.exe
- Select "scatter-Loading" and search MT8173_Android_scatter.txt in ROM
- Wait file to be added into Flash Tool
- Select "Download Only" or if upgrade "Firmware upgrade"
- Turn off your phone (and don't turn on the phone).
- Press “Download” button to start
- and connect your phone into the computer via USB data cable.
- The process will start and a red progress bar will appear after color purple, yellow.
- And green circles display
- Finish !
- You can now safely disconnect your phone and turn it on.
So you should look for your ROM/FIRMWARE and than flash it. Key step for you is to turn of the tablet, push download button in SPflash tools, and then connect USB to the tablet. Flash will then start!
But Google for instructions on how to use SPflash

Thank you, BiG_FooT and fastmix! Leaving it in power off state before SP flash was the missing step. I don't know how I missed that in previous Google searches. Fully working tablet now.
I now have two of these things. If you (or any others interested in developing this Mediatek) want me to use one of my Teclast T8s for testing for you, let me know.

Has anyone successfully flashed the firmware??
The system.img for all the ROMs is corrupt

Hi! I have an Alfawise Tab (rebranded JDTAB 01) with MT8173 chipset and android 6.0.
I managed to find the stock firmware and recovery, so i tried to port this TWRP recovery: https://forum.xda-developers.com/mi-pad/development/recovery-twrp-3-2-1-0-mi-pad-3-cappu-t3744185 unsuccessfully, maybe because of the different android versions(?)
I don't know....
Does anyone know how to port- build a custom recovery for these chipsets (mt8173-76)?
Or know if there is a working TWRP based on android 6.0 and these chipsets?

So, is there still any development? Where kernel-sources for Teclast devices can be found?

What an utter failure. Of both the manufacturers and the community.
It's fairly clear that the problem is hardware fragmentation. There is just too much diversity in Android hardware platforms, even too many different ARM-based CPUs, and too few users on many of those to justify a major development effort for any of them.
The moral of the story must be: if you want your tablet to remain useful for more than a couple of years, don't buy a cheap Chinese generic one made by a company that isn't a famous global brand. Stick to hardware that has sold in the millions.

The moral of the story must be: if you want your tablet to remain useful for more than a couple of years, don't buy a cheap Chinese generic one made by a company that isn't a famous global brand. Stick to hardware that has sold in the millions.

What we really need to do is reverse engineer a few roms already built for these chipsets, then see what they all have in common. This will help us figure out what needs to be done to the kernel, and what firmware we need.

Any news? Has anyone tried to flash GPD firmware on one of the other tablets with the same chipset? I have a Chuwi Hi9 with MTK 8173 and I would love to be able to change the ROM, the default one sucks big time. I actually bought it because it had the same chipset as one of the GPD devices.

Where To Start??

Hi,
If I were you I would start by having a really good look through the MTK_X20_BASE_AOSP open source code here https://github.com/archermind/MTK_X20_BASE_AOSP
In that you will find all the required mtk binary's and documented associated google dependency's and stock mtk app's needed. Dig through all the make files and compare your project_confg which should be in your system/data/misc on 6.0 and vendor/data/misc 7.0 with the one in that source to see whats built.
Because it's mediatek it's messy and things are all over the place but after days of reading it you can kinda start follow the rabbit eventually :laugh:
Take what you need and assemble it into a nice logical fashion using a experienced dev's work as a example and try a AOSP build if that works then try Lineage.
When you have things stable follow others who have stepped up in firmware version.
Most things should work if you have a working kernel.
Best place to start would be HERE it's invaluable :good:
There are other places and make's for BT WiFi GPS etc etc so ensure to explore it well.
Obviosly get the blobs from your own device if poss else pinch them form that source and give them a try it's all trial and error.
If I ever find the time I may join you one day to build a rom for the Lenovo Tab2 mt8165 please note most of these mt8xxxx have a equivalent mt67xx/mt65xx see my sig below for a example.
Good Luck and Happy building :fingers-crossed:

Hello!
Do I have a chance to do this with my teclast T8 device if I don't have even kernel-source code? For now I've ported most of firmwares different from my stock ROM (MIUI, ZenUI etc). But I would like to upgrade android version ( Nougat to Oreo) if it possible. Since not so long new device ( alldocube X) was released on same chipset (mt8176) with installed android Oreo, maybe this may help some way?

Hello To All
I have a Teclast M89 That I rooted with Magisk and have a working TWRP for backing up.
I am very interested in Testing Kernels and new Roms.I have already wiped and reflashed device a couple times -now Everything for testing,flashing, and booting has been verified.

@Goayandi
Just stopping by to say thanks for this, used some stuff from here for lineage-12.1 on Fire HD10
