Hey. Ive done a few mods and upgrades already, but one thing has always stumped me about android os and apps. Can anyone explain the variations between the different roms? I understand that the scale and power difference between say a phone and a tablet cause there to be differences, but why is there such gulfs separating to almost identical devices? Take, as a possibly poor example, a yarvik 10.1" tablet and an almost identical viewsonic 10.1" tab. what would stop the viewsonic roms from working on the yarvik? Apologies if this has already been answered somewhere else, I haven't managed to find a similar thread to answer this for me.
Thanks

The main reason the ROMs aren't able to be used on both devices is because they have a different chipset and hardware. And ROMs are designed to work with the specific hardware of a specific device. The only way to get them to work on other devices is to port the ROM you want to that device (Porting ROMs ranges from pretty straightforward to extremely hard).

First let me introduce myself. The name is Darcy and I have been casually using linux and other *nix OS for about a decade. I am in school working on a programing degree ATM, and am a pretty quick study. Anyways, I without much research bought my wife a generic 7" tablet running android 1.6. I know what processor it has and Im hoping that leads me to a place to start. Ok so the device is a "Kasser Net'sGo" we didnt realize that its just a china pad with another companys name on it when we ordered it. So most of the apps dont run correctly, and in general the device sucks(on a software level the HW is fine although generic).
Anyways it apears that i can get into recovery mode to flash if i had no other choices. But since there are no official roms im hoping to find a build thats based on the same CPU or similar hardware to find a starting point. Its running the Marvell Aspen 800mhz chip and standard ddr2. Sadly thats all we have been able to find out about this device.
I have compiled custom builds for linux before, and i have now purchased a Gtab so i have a less garbage device to test some things on(i have allready flashed 2 different roms and fooled with a bunch of the settings). But we would realy like to do something with this other tablet. So if anyone can point me in the direction of some info on how to do android builds or a repository of chipset drivers and such that might help me that would be greatly appreciated.
This is a nice little tablet and I was wondering if anyone had successfully ported a rom to it yet. From a bit of research, mainly here and here, rooting is defiantly possible with a little finesse.
Besides getting android market and google app bundle to work, it would be great to have a custom rom for this tablet. If anyone is willing to take this on, I'd be more than happy to donate and post a system dump.
Well I have also done some research. The leader i7 tablet goes by another name. IT is apparently some re boxed tablet... lost the name. But stay tuned as i will post it here when i find it. But the reason you wont find roms or tricks for this is because theres another name. Find its root hardware before rebranding and you will find roms
Its other name is the impression 7.

It is an "Infotmic" based MID. Particularly the x210 model.
Listed in the hardware information program i used.
Theoretically its internals are the same and it can be flashed to anything the infotmic x210 tablets have listed on various sites, as the only difference would be the external ports, case and etc for the rebranding.
This is good and makes sense because if you were to mass produce a cheap tablet, you would want the insides to be universal (it saves money) but modular enough to fit into different rebranding schemes. (easily resolder/connect additional or less IO ports on main board)
Spread the word on any forum you find, see if we cant and find some people smart enough to crack open these F***ers
Hello
I am going to try my hand at porting. I have the 3113 Galaxy Tab 2 7.0), and am wondering if someone can point me to the best/easiest device to port ROMs from. Ie., Similar specs (screen size, processor, dpi, etc., etc.) I considered using the tab 2 10.1 to port from, but I wasn't sure if the screen size would force me to re-size all the png's and/or whatnot, but I know the hardware is almost identical. I just want to extend my abilities to dev android, and figured this might be a fun way to understand and learn android on a different level. I've found and read many threads on porting and am pretty excited to dive in! Any info is greatly appreciated, especially in regards as to which device to port from and why. Thanks guys/gals!
Anyone?

Hi Recently purchased a tablet for which I am not able to find any custom ROM. The configuration is as follows .
processor - 1.2 Ghz Cortex A8 Dual Mali 400 2D/3D core
The model of tablet is Micromax funbook Infinity p275. I have gained the root access for the tablet but cannot find any custom ROM for it .Is there any ROM for a device that will work o this device too?
I ran the application "android system info" on the device and found the following information
CPU-ARMv7 Processor rev 2(v71)
build info-
CPU ABI-armeabi-v7a
The tablet does not have any volume rocker keys.It only have home and power keys in it and a reset button hole.
Thanks

This is why I would have found out if there was support here on XDA first before purchasing. I don't understand why People buy cheap or uncommon devices then come here asking for things like ROMs or rooting.

because not everybody have money like you to afford the tablet they wish for, and I think that's the forum for, to ask help, nobody hit your had, and nobody will, if you won't help, so stop with those noob answers.
You can always buy a used tablet that *used to* be popular and thus has development from when it was or might still have some going on.
I would not buy such a tablet unless I planned on playing it to try to make a ROM myself - if it was even possible.
You can get a decent Android tablet with decent amounts of development for like, $100 new so I don't think it's asking that much when it comes to buying a "gadget" that's not necessary.
1) I'm hoping someone can advise pls! I'm a very light user mostly for wsapp and sometimes maps/gps when walking (no gaming and occasionally watch youtube videos) so was hoping to find something £40-£50.

There are others I'm looking at but they don't mention anything about the processor (sometimes it'll mention the number of cores but no name)? The specs seem way better than even xiaomi phones for the same money, I know there's gonna be no support updates etc. how important is that? Couldn't I just search for a custom ROM, try to upgrade to higher android version etc? Would it be difficult/impossible to find roms for an unbranded phone?
Also I've read that there's a possibility they could just be sneaky re-brands so potentially could be getting a xiaomi etc. phone for less?
2) I'm also considering paying a bit more if unbranded is a no-go. Xiaomi Redmi 7 3GB/32GB around £100 vs Xiaomi Mi Play 4GB/64GB if it's £6 more?
I like the extra ram and storage for only £6 more but the battery seems better on R7 and larger screen

I've seen some advertisements (on wish.com or Ali Express) for devices with no apparent name brand that mention having 10 core processors, dual sim, Android 9 and more. These are all MTK devices which pose difficulties if you want to flash a ROM into them to upgrade or change something. RCA tablets are MTK devices and I, along with many others have spent a lot of time just trying to gain access to such devices. It's been done. However, it has been more than difficult as of yet to find any compatible ROMs and these devices are extremely picky when it comes to using other ROMs. For those of us that are currently still working on it, we have yet to find anything compatible. That's not saying they are bad devices, they are actually pretty good I've had mine (the RCA Maven, Viking and Galileo) for years with little problems.

Thanks for the reply. Any MTK processor devices are difficult/unlikey to have custom roms or tweak/upgrade in any way?

Theoretically there should be, but many here would rather work on the newest devices most of which are not MTK (Media Tek). They're not built like Samsungs and if you open one up the whole motherboard is the size of today's phones or roughly one quarter the size of the tablet which could be the reason they're so cheap. The only thing I've been able to flash into mine is the original stock firmware, anything else led to bricking. And recovering from a brick is difficult the SP Flash tool is nothing like the Odin3 we use for Samsungs.

I have also bought uhans u300 and took a look at the Development & Support topic here, there's absolutely no way to upgrade it from Android 6.0?
