Hi, I have this device called the Bluewave Wave 8 HD+ running Kitkat 4.4.4. Bluewave, the manufacturer, decided to sell a whole new device with the same chip (Rockchip RK3288), same everything but with a new version of the OS and a bigger battery instead of just providing a software update. Their first device in the lineup was my device. Their second device was the Bluewave Wave 8 HD+ Lollipop. Their third is the Bluewave Wave 8 HD+ Marshmallow.
Here's the thing. I've got the Kitkat one. I wanted to upgrade to Marshmallow. So I flashed the Marshmallow Rom from the Marshmallow Version of my device to my Kitkat Device. At first boot, the screen was blank but with the backlight on. So restarted the device. I then discovered that the OS was actually booted. I discovered this when I connected the tablet to the TV. Everything works like the touch screen, etc. except for the tablet display.
Does android require appropriate drivers for the display?
If it does, Can I just copy the display drivers from the Kitkat Versio n to the Marshmallow one?
I can't seem to figure this out why the tablet display is blank.
You can check out the tablets I've said earlier on their website on Bluewave Global. This company really sucks in my opinion. They decided to sell another device instead of just providing an upgrade.

Thanks for taking the time to read my question! A few months back I bought this cheap car head unit:
ALLWINNER t3
Android 6.0.1 KOT49H
Although it works quite all right (considering the price) the operating system is hardly customizable. Even basic OS updates cannot be installed. To get acces to the full OS I 'd thought I 'd better root it. Turned out to be impossible... so far.
I tried software options while finally One Click Root congratulated me. "The device can be rooted". But when problems occured the helpdesk just said "the device cannot be rooted."
Problem seems to be that installation of OS is so right that there is no acces to Developers Mode and USB debugging. Can this device not be rooted or anyone familiar with a workaround?
I want to install special Android version: Android 9 Pie GO because it has lower requirements 512 MB of RAM . My phone has 1GB of RAM but problem is I don't see option how to do that.
My phone: Medion E4503 doesn't seem to be supported on twrp website for making recovery point first. I don't see it under devices. I heard this phone may just be rebrand of Lenovo phone (dunno which one ) but I have no way of telling which Lenovo version may work if at all. And that is just pre- install part. Then I also don't see where to find custom ROM for this device. I only see bunch of other ROMs for other phones. I have Android 5.0 and banking application now require Android 6.0+ . I do not want to buy new phone just for that because I rarely use phone at all.
As you can all see there is android 10 out.
Just wanted to warn all of you who like to switch often from android 9 to android 10 and vice versa, that the first firmware for most of the countrys that came out on Sammobile is A750FXXU4.... which means the bootloader is Rev.4 the same like for the last Pie rom
That means you can rollback to last Pie firmware from Q with Odin.
Eventualy samsung will update firmwares with new bootloader, security fixes, and ect...
So it means if you update your firmware with rev.5 bootloader when it comes out, you will newer be able to go back to Pie.
Some of you probably know that, but there are others who dont know that so just to be careful.
i want to ask question .. samsung provided device update that includes Android 10 for Galaxy A7 2018 ,, and with this update Device becomes slow .. games become to lag alot .. it takes a lot of time to switch from rear camera to front camera these problem were not there when the device was android 8 and 9 ..
and i add to add one more thing that i was using the device care widget of the phone itself .. which told 2.6 to 3 .0 gb free RAM in case of Android 8 and 9 .. and since the Android 10 maximum RAM I have free is only 1.6GB even after FACTORY RESETTING and REBOOTING the device .. what should i do ??
I'm will not recommend to upgrade Pie to Android Q because its still buggy.
First let me say; I am not a developer. I do not work in the software industry and I have no experience writing code. At home I do run a dual boot system (Kubuntu 20 & Windows10) and I have previously successfully installed LineageOS on a couple of older devices (a Dell Streak 7, Samsung Galaxy S4 and more recently a Nokia 6.2). So, I have a rough idea on how to accomplish an install if there's a clear path toward the goal lol.
I have a (rooted, unlocked) Dell Venue 8 7840 running Android 5.1 and I'd like to see if I can load a custom ROM to update to maybe Android 7. I realize a 5 year old tablet (with Intel Atom Z3580/2.3 GHz quad-core) won't likely be capable of running anything as recent as even Android 10. But this device seems to be a unicorn of sorts. That is, I can find no mention of codename 'moorefield' on any developer message board threads.
How can I support development of a custom ROM for my device? I have used ADB before and can provide copies of any files that might be needed for creation of so-called "proprietary blobs". I find it confusing and misleading that; in order to build a custom ROM someone needs to have previously written one for you device.
Does anyone have any suggestions on how I can proceed?
I have the same device and the same questions. Everytime I go to get rid of the device I pick it up and fall in love with it again. I still haven;t found a device that is better weight and size wise. I would love to use for a different purpose but Anroid 5.1 holds it back.
How did u rooted the device

Hello Everyone!
So today something really interesting happened with me...... I'm feeling okay but i'm kinda nervous too.
I had rooted my phone earlier and flashed Lineage OS but i was encountering lots of problems so i tried to flash phone's firmware with odin.
My phone was Samsung Galaxy On7 Pro. I installed a firmware file and flashed it. But unfortunately, the firmware was of Samsung Galaxy On7 not Samsung Galaxy On7 Pro. When, i installed it, i encountered a DRK error! Then, it took me to Stock Recovery. From there, i wiped cache and internal storage and rebooted. It somehow worked very correctly. But now whenever i reboot my phone, i get Galaxy On7 logo not Galaxy On7 Pro. I don't know what happened but it's a MIRACLE of Android.........!!!!!!!
So, my queries are as follows:
Now, i'm stuck on Android Lollipop (5.1.1). There is a OTA update available within the system because it says its official now. What if i update? Will it even update? Or it will brick because phone model is different and firmware is diffrent?
Will it run smoothly in the situation where it is? (Note: I have not encountered any issues till now. Both Software and Hardware work well)
So, Miracles can happen in android world as happened with me.
Glad to hear you were able to unbrick your phone!
First a warning, I have no experience with your particular phone. But, I would think your update would go through. Usually the Pro and non-pro models are very similar and that is why your firmware worked. There might be some weird functionality in some areas like the camera or modems.
So, you can try the update. Worse case, you flash the On7 Pro firmware instead of the non-pro version again.
Well, the software updated and worked. No issues at all.
But i'm still confused how did it even work........
Anyway, i'm back to Marshmallow (6.0.1) again.
Everything works fine. I tested most things and all work correctly. I think Samsung just gave 8GB storage in non-pro version and 16GB in pro version and software is same xD
I also got new bootanimation and phone turn on sound from that
Moreover, i ordered a new Samsung M31 as i wanted more storage
But problems on older phone are also solved
Now, i will keep 2 phones
