Android OS

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).

[Q] which rom will work on following config ?

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.

Has anyone bought generic unbranded smartphones available on ebay etc?

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.
https://www.ebay.co.uk/itm/M20-Pro-...var=564119885073&_trksid=p2055119.m1438.l2649
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?

Specs and Information

Hello there!
I would like to know which specifications should i know before looking for a ROM or another, due to the fact that i haven`t been able to see many ROMs on this subforum.
There are a couple of them i would like to try, but sadly i dont find them over here (one of them is CorvusOS, and the other one is ParanoidAndroid).
Give all this information, and having tried to read and inform myself a little bit, i have found several things i would like to know before doing anything:
I have a Redmi 9AT, which if im not wrong "similar" to Redmi 9A. There is a custom ROM for Redmi Note 9 Pro, ¿could it work a ROM for that device, work on mine?, if it weren`t the case, ¿which specs should i look for?
I have used this page to compare these 3 devices.
If it weren`t possible none of them, i would at least like to try ArrowOS, but before anything i would like to know your opinions

A Custom ROM must be tailored to device's hardware specs to work properly.

Yes! I have read that, but i wonder if with changes on specific fields (for example on this case, CPU and GPU) could still be viable.
Like most of the other components, seem to be similar
Thanks for your answer

Tablet custom Roms

Hi there,
I noticed that there isn't as much activity for custom Roms for tablets as there are for smartphones. I wonder why. Is it because there aren't as many tablets as smartphones and therefore there is less interest in building custom roms?
I wanted to buy a tablet for my mother ( Chuwi HiPad Max) and noticed that the manufacturer doesn't have a good reputation for updating their devices (just few security patches and that's it), so I looked here on XDA with the hope of some custom roms but couldn't find any (not only for this device which is fairly new, but for most tablets even of other brands).
Should I buy a specific tablet (not more expensive than 200€/$) that is known to have more roms? Do you have any recommendation? The tablet will be used for watching Netflix/Prime Videos/YouTube, emailing and internet surfing.
Thank you

Purchase the 8-inch Amazon Fire HD 10 ( 2021 ) tablet ( cheapest one ) or the 10-inch Lenovo Smart Tab P10 tablet: you can get both on Amazon.

Custom rom development is based on people using the tablet and being interested in making other custom roms for their tablet. Either those who are developers don't have a need for a tablet or there are developers without an incentive (money) to develop a custom rom. Developing a custom rom takes time, even months. Why should someone invest months without pay? Thus the lack of custom roms. Now you could try your luck with generic system images. Those are kind of a custom rom. Made to run on an unlimited number of devices, smartphones and tablets included.
