Ram upgrade allwinner cpu - Android Q&A, Help & Troubleshooting

Hi guys,
The story goes like this: i have an old chinese navigation unit that has an allwinner cpu T3 with external Ram of 1Gb. I found an 4Gb ic on a PX5 Rockchip board and decided to do the swap. All went well, the device boots up normally but only sees 1Gb of Ram. Question is where is the ammont of Ram written in the OS or how do I make the OS see the newly installed Ram? The device is running Android 6 or so i think( api 23) but it reports android 7.1 in about screen. I managed to get it rooted. I know it is weird to waste my time on such an old device but since i'm in quarantine there's nothing better to do.

sounds like a kernel issue to me

[Q] How to change the OS of a cheap no name tablet?

I have a cheap no name tablet with the following configuration:
1. Cortex A8 1.20GHz single core
2. 512MB DDR3 ram
3. 4GB memory
4. Android 4.2.2
5. 7"
Is there a way to change the OS with a faster smoother one? It doesn't matter if it's older than the current one, i just want to be faster and smoother because with the current one (4.2.2) the tablet simply lags horrible, it's unusable. Also it doesn't matter if it's official or custom, i need something to make this crap work faster or i'll throw it on the window.

[Q] Custom ROM, how to change the ram size value?

I have a tablet with these specs:
Rk3168 dual core arm A9 cpu, 1GB RAM, 8GB storage, 7" 1024x600 display, wifi rtl8188etv
I managed to mess it up and I can't get my hands on the stock ROM.It has no volume buttons either so couldn't recover it.
I found a few working custom ROMs for it but none of them match my device perfectly.
Some of them don't have the wifi drivers I need and a couple I found with the correct driver don't have the correct RAM/ROM size.
From my understanding I have to work on the kernel files to either change wifi drivers or ram/rom ones however I can't find a guide on the later. I only found a guide on the wifi.
Can anyone tell me how I can change the ram/rom files?
Or is anyone aware of a fitting custom rom I could use?

Flashing... incorrect preloader problem... bricked tablet...

I have this friends tablet for a week or two.
I found, i think, right firmware, and that's one problem solved, i hope.
The other problem is, i got this tablet along with the flashing problem. I think SP flashing tool was used, but with a wrong firmware, and now is preloader messed up... (sry for my bad english)
Name of the tablet: Xwave Xpad 3G-701
Now, my problem is that i can't access anything, tablet just won't strat, computer can't recognize it, and so on, dead in other words.
specs:
OS: Android 4.2 Jelly Bean
GPU: Mali 400 MP, 3D OpenGL (ES 2.0)
Screen: 7 inch, 1024x600
Processor: 1.3Ghz Dual-Core ARM Cortex-A7 (MediaTek MT8312)
Ram: 512MB DDR2
Memory: 4GB
Motherboard is: ELINK_MR706_D3_V6 20140114
To avoid any forum rules problem, i added only dropbox link paths off the images... so i could explain my USB issue.

dropbox.com/s/qefe24v4l6o96pj/DSC_0117.JPG?dl=0 -- motherboard
Computer can't recognize it, i tried many variants, it's just not working.
In motherboard picture, whole surface is covered with protection, only some ponits are accesible.
My question is, what is the procedure to unbrick this tablet particularly... to force the right preloader in it, and become recognisable by computer? The rest might be familiar to me.
Is it required to detach battery, as some procedures suggest...?
My apology if this is somewhere else asked, i just couldn't find ant explanation for this model.
If my question is unclear, i'll add any info or change needed....

Getac T800 Tablet - Switch From Win 10 OS to Android

Hi there,
So I am experienced in rooting and flashing / rooting phones (originally did this with the Samsung fascinate and B&N NookHD). The company I work for recently bought several Getac T800 tablets. These tablets come with Win10 preloaded. For the work I want our field staff to do, there are several apps that are way better, but run on Android. I am hoping that I will be able to load Android onto these machines (I do not want to do a dual boot situation - The staff using them are not tech savvy).
Specs for the machine can be found here: http://us.getac.com/tablets/t800/specs.html
Intel® Atom Processor x7-Z8750 1.6GHz (up to 2.56GHz); 2MB Cache
8GB LPDDR3
128 GB EMMC
This company makes a similar machine that runs android
Specs for ZX70: http://us.getac.com/tablets/zx70/specs.html
Intel® Atom™ x5-Z8350 Processor 1.44GHz, burst up to 1.92 GHz 2MB Cache
2GB LPDDR3 expandable to 4GB
32GB eMMc
I can download the BIOS and the android 6.0 ISO (for the ZX70) from the company here: http://us.getac.com/support/drivers.html (type in ZX70 and submit)
My question is could I use this image on our T800s and what would be the steps to load the image onto the machine? Are there any pitfalls / drawbacks?
Hi, I know this post is years old, but I'm trying to do the same thing. Did anyone reply to you, or did you figure it out? I want to try to install their Getac android image on one of their windows tablets.
I have successfully installed a different android OS on it, but I can't install the Getac OEMConfig app on the current android OS. I believe it is because it isn't showing up as a Getac device or the android OS version is too new. I would love to find this app, but I can't find an APK for it anywhere, either.
