I have a couple of questions for the Rom developers/experts on here regarding things that can be done with Android ROM's.
Is a parser Rom upgrade possible? So is it possible to change a small part of a ROM and then allow users to upgrade their ROM easily?
So can I change a part of a ROM and then a customer can upgrade to the newer ROM without having to be technically savvy and needing to root and flash their devices?
Can a change be burnt into a ROM so that when a user selects "Restore Factory Settings" that it doesn't remove the upgrade to the ROM?
So essentially I want to know if its possible (with a device manufacturers permission) to add to a ROM some small additional parts and then give this new ROM version as a firmware upgrade to the device so that a user only has to "upgrade" and not go through the process of rooting and flashing there device?
I dont think that is possible. But then again I am no expert.

Currently I'm having HTC HD7 with Windows 7.5 (7.10.8107.79) Chevron unlocked (9$) ..
Now i need my device to be interop unlocked. I know there is no other way than reverting back method (Healthcliff)..
So, I'm planning to flash to custom roms like DFT
Now Consider that i've flashed custom rom, (not flashed actually now, just consider! )
My questions are ,
1.How can i revert back to official rom , if i need to claim warranty?
2.Will i be able to update the device through Zune (after flashing custom rom)?
3.How do i connect my device to computer, does zune recognize it ?
1: Flash a stock ROM. There are many of them available for the HD7. This should also restore the OSPL.
2: Some ROMs are updatable directly. Others can receive CAB files but you need to send custom CABs. Others can't be upgraded. Read the details on the ROM you flash; there is a considerable variety.
3: Yes, Zune will recognize and sync with a custom ROM (assuming said ROM isn't completely and horribly broken).
Hi all, I'm relatively new to the Android world and seeking help from experts here.
I recently bought a used S7 (SM-G930K), it came with Android 8.0 and I want to downgrade to 7.0.
I tried downgrading using its stock firmware with Odin. Attempted many times but only realized that it can only be downgraded as far as the bootloader version goes.
Think my S7 was on bootloader version 2. So as checked for the available stock firmwares, the "earliest" version 2 was still on Android 8.0 (PDA G930KKKU2ERJ1 and CSC G930KKTC2ERJ1).
Anyone can advise me how to go about downgrading to Android 7.0? Though this S7 may not be my primary phone and there's obviously no warranty, I won't want to brick anything.
Do I have to downgrade the bootloader version to 1.0 first? And how do I do that?
Apologies, do excuse these noob questions, I'm not familiar with many Android terms. Cheers!
Model: S7 SM-G930K (KT Telco)
Android version: 8.0
Baseband version: G930KKKU2ERJ1

Basically, on Samsung phones, once you upgrade your bootloader, they put a lock on it, so you can never downgrade it, for security reasons, of course.
The only thing you can do is flashing custom rom, or stock rom with custom recovery & kernel.

I see, now i understand why..
"Custom roms" - does this mean it's made by users like us? And what does "stock rom with custom recovery & kernel" mean?
Can you point me where can i find these roms for my S7? Is it the same as flashing them on Odin?
Many thanks!
Yes custom ROM's are community made. The kernal is kind of like the foundation that sits beneath the ROM, so you can use the official ROM but run a custom kernal to tweak phone behaviour.
Flashing ROM's involves using TWRP instead of Odin. If you're going down that path I would recommend you read very carefully and educate yourself, instead of just gung ho'ing it. Wouldn't want to brick your device.
It's also worth mentioning while you can flash an older custom ROM via TWRP, that doesn't downgrade your bootloader with it. Having a newer bootloader on an older ROM can cause issues.
Most custom ROM's are also made for G930F, while some also support the G930K you may want to make sure before flashing anything.

Definitely will be more mindful as rooting does involve some kind of risk of bricking my phone.
Wow that's great info, really appreciate you explaining this to me.
Something new I've learnt! :good:
Hello. Yesterday i installed latest OTA Android version (TB-J606L_S320030_210923_ROW) and noticed that it is really slow and it has even more bloatware that i don't want. I don't need to root it (because of bloatware removal) as i also need to revert it to default state as it was before update.
1. It is possible to find which version i had before this upgrade?
2. How could i downgrade system to previous version (i think it was Android 10 but i'm not sure)
PS: I successfully downgraded/rooted some devices but as every brand has it's specific way to perform downgrade, i'm asking here. Any advice would help and i'm aware of dangers of downgrading/rooting devices (bricking). In any case, it would be awesome to also link unbricking guide for TB-J606L, just in case It's always better to have plan B.
Update: I found source of roms for my device but i can't recognize which versions are old Android 10 and which are the new Android 11.
Hello and good day everyone,
I am facing alot of unfamiliar behavior because of the Chinese Rom also i can`t install the Global Rom as per the Nubia Tech support.
So i decided to root my device and install a custom rom that i can do everything i want as per my older android devices.
I looked on many sites but i didn`t find any repo i can install it on my device!
Does anyone know of Custom Rom that is support on Red Magic 7 Pro????
The device just launched globally and there isnt even a TWRP build yet.
You will need to wait quite a while, even then, this is a very niche device and might never get a custom rom.
That's unfortunate news for me!!!!
The device is one of the best I have ever used,
But the Android system they installed on it is Bull......
That's something i'm very concerned over, I wouldn't want to purchase a device that doesn't have any custom roms available , I much prefer clean stock android or pixel experience roms , it's concerning to consider this phone may be stuck with only firmware updates from the official manufacturer, I also tried looking for older models from redmagic and they also seem to have very minimal to no custom roms,
I don't trust redmagic with keeping up to date with android judging by how older models also not getting any firmware updates to android 11,12,13...
I am personally holding off from buying this phone because of this factor , likely will end up buying a different phone if something more interesting will release from a more known manufacturer with better custom development community
Actually, this device is not compatible with Twrp.
We have to wait a long time to see a custom rom.
I want to edit the hosts file of a moto edge (2021), however I also want it to continue to get OTA updates. So some (potentially dumb) questions:
Can you get OTA updates on an unlocked bootloader for motorola?
Can you get updates after rooting then unrooting the phone?
Will the hosts file changes made while rooted remain after unrooting?
Thank you for your time and help, much appreciated!
Hello, I have seen your publication and I want to give you an answer based on my experience with my Motorola phones, I am just going to try the custom rom that is available for this phone.
but I can clarify certain doubts
Regarding the updates, they continue to be received even if your device is unlocked, that is the answer to your first question,
second, once the phone is updated you can lose the root since in the updates they lose the modifications to some files like the boot.img.
and in the same way it depends on the update but if you can modify the host file.
But I am still going to recommend that you do not update the phone when you have it rooted, since in some update some changes are reverted and it may remain in the bootloop
I hope my answer helps you and I repeat this answer is based on experience with motorola phones
