A decade or so ago, was a frequent visitor to XDA Forums to custom mod my HTC phones.
Fast forward to late last year, long story short, picked up a fake Samsung s22 ultra which was a cheap Chinese knockoff with whatever generic android version it has installed
It reports its using Android 12 and that's about it.
In its current state, the performance is very very slow, and can take a couple of seconds to navigate between screens, launch apps etc.
Is there any generic custom roms I could throw at this thing?
EDIT - here's some relevant screenshots

Wondering if my newly purchased (used to be Sprint phone) LG G8 will have any issues being used on my T Mobile account? Will there be any issues with speed or any hiccups or incompatibllities (or disadvantages compared to having a dedicated T Mobile version of the G8?). Thank you. Also wondering... does anyone know if this phone is due for an Android 11 update anytime soon (and is 11 reviewed more favorably than 10 by most?)? Thanks in advance!

I hope this is the right forum.
Been lurking for a long time. Next month I will need an app for my Casio BLE watch (not a smartwatch).
The app would require investigation on communication since I have no documentation.
I know it's possible because there already exist a few app that do that, however for different Casio model.
Where would you post such an offer?
I've tried fiverr, to no avail.

I never heard of them, but those watches seem pricey to me (and I hate wearing a watch).
Since you're talking about a specific model the developer would need one.
Now, if you had a case of these watches and you could trust somebody, then I'd say offering a watch to somebody to develop an app for it could work.
Still, to make a fancy app to your spec is a ton more work than knocking off some quick-and-dirty watch link.
Bluetooth can usually be pretty easy to reverse engineer, especially if you have a similar Android app to disassemble.
I am new to the realm of Android and especially embedded style devices. I have not disassembled the device yet but I do have photos of the internals with high def photos of only a few devices. The platform is based on a Qualcomm WTR4095 (Transceiver), Qualcomm QFE4320(??), Qualcomm MSM8909 (Snapdragon 210), WCN3610(WiFi, Bluetooth, FM?). It seems similar to structure of the Samsung Galaxy S7 Edge from some light googling.
My problem is that the cellular service for this device is no longer supported. My question is, is the SIM data embedded in one of these chips? If it is, how would it be possible (if at all) to get this device working with a new cellular network plan. If the SIM data is not embedded what sort of device on the circuit should I look for and how would I rig in a new SIM?
Let me know if I need to fill in more information but this seemed to be the best place for me to start asking for some guidance on the road ahead!

No worries, thank you for moving it to the correct forum. I will review the guidances for future reference.
I'm not sure if this is the right topic for it.
But I was wondering if I could change the firmware on a cheap (YC-83p) tab.
Got it as a welcome gift from a course I got started. So don't have anny reasons to compain at all.
It doesn't has the greatest specs but it handles some basic stuff pretty well. So it's actually decent for bringing along on vacation or use it as a Home Assisstant controll tab.
It's actually this tab with slightly improved specs. (2GB of RAM instead of 1GB etc.):
Portable 8 inch Android 10 WiFi Tablet - YC-83T | Portworld Manufacturer
2021 New Arrival Portable 8 inch Quad-Core Processor Vertical Display 800*1280 IPS Screen Gms Android 10 1G+16G Android WiFi Tablet
portworld-solu.com
It's actually just fine as it is. But it seems it has some custom firmware onit, at least showing a custom bootscreen of the instution of the course. And I would like to change it if possible.
I searched the internet, but there's actually not much to be found.
So my question is if someone knows how to reflash this kind of devices, or at least change the bootscreen? I would prefer the first option if possible.
Thanks in advance!
edit:
It's running Android (Go edition) 11 btw.

Oh thanks! I already thought it was the incorrect toppic. But it was the best option I could find at the moment.
Totally missed this Android Q&A somehow

Thanks, but I actually don't think it's rooted. Didn't cheked it yet though.
Actually looked for a way to root it, then it would be easier to put custom firmware on it I guess. But there's just verry little to completely nothing to be found of this tablet.
But I asume there must be a way sinse this institution was also able to customize some things.
Some questions:
How locked down is the tablet? Can you access gms services? Can you freely install apks? Are there developer options in settings and does it have the OEM unlock toggle?
Try to install adia64 and 7-zip. What is the processor? If it is mtk, you might be able to temp root your device.
Reviving this as I got this tablet as well and looking for possibilities.
I have posted here about my progress https://forum.xda-developers.com/t/can-we-root-this-tablet.4560407/page-2#post-88355463
Tablet is pretty generic but I don't seem to find any resource about it. Any ideas?
Hello All,
I'm a complete noob but am interesting in taking a (cheap) android phone and replacing the UI with a custom 'ROM'.
Can anyone suggest which brand and/or model of phone is good for one's first attempt?
Alternatively, is there a reputable company I can pay to have this done? (I'm in the West Midlands, UK.)
Many thanks

A Xiaomi phone with Snapdragon CPU is a good choice. Like Poco x5 or redmi, but with Snapdragon
