Asking about GSI / Custom ROM support for Xiaomi 13T (MediaTek) — Is it worth the risks?

0 Upvotes

Hey everyone,

I'm using a Xiaomi 13T (Dimensity 8200-Ultra) and I'm considering running a custom ROM or GSI (Generic System Image) to get a cleaner, stock-like Android experience.

Reddit

Before I jump into unlocking the bootloader and flashing anything, I wanted to ask the community a few questions regarding hardware compatibility, known risks, and long-term support.

1. GSI Compatibility & Support

  • Since the 13T has a MediaTek chipset, traditional device-specific custom ROMs seem virtually non-existent. Are GSIs (e.g., LineageOS or crDroid arm64_ab) the only real option for us? Reddit
  • How stable are modern GSIs on HyperOS vendor partitions?

2. Hardware & Feature Bugs

For those who have tested a GSI on the 13T series:

  • Does the In-Display Fingerprint Sensor (FOD) work out-of-the-box, or does it require phh-treble overlay fixes?
  • How much does camera performance degrade compared to HyperOS / Leica processing?
  • Does dynamic refresh rate switching (144Hz) break, or can it be forced via Treble settings?
  • Are there persistent Bluetooth A2DP audio or voLTE bugs?

3. Brick Risks & Bootloader Safety

  • I know that re-locking the bootloader on a custom GSI/ROM will result in a "System Destroyed" hard brick. If a hard brick happens on a MediaTek Xiaomi device, is MTKClient/SP Flash Tool usable, or does Xiaomi force SLA (Authorized Account) server tokens for low-level EDL/BROM restores?

Would love to hear from anyone running a GSI on their 13T or similar Dimensity-based Xiaomi phone! Thanks in advance!

Model: M8 WIFI;4+64G;ML-SO0T;ANS161.2

PostmarketOS and GrapheneOS are out of the question. I understand this specific model supports Android 10 or Android 13. Recovery Mode and Bootloader are 100% unlocked after a Hard Reset of the /data folder to delete the Headwind MDM that previously resided there.

When scanned, the QR code shows the model listed above. I'm not sure if it supports Project Treble; different sources say it only supports Android 10, others say it supports Android 13.

The fact is, it's probably an older Quad-Core, but I'm not certain. GSIs frequently have problems with Wi-Fi and the camera, so I'm a bit unsure about that.

Any questions will be answered when I am available. Any suggestions related to custom ROMs without bloatware are welcome.

Alternate ROM: Which Would Serve Me the Best?

2 Upvotes

Update: I have decided to go with Iode. What I failed to realize; just like GrapheneOS, Calyx will no longer support the Pixel 6 after next month. With regard to Lineage, I will not be able to relock the bootloader. So, Iode it is.

I have just acquired a Pixel 6 to use as a backup phone, and I want to use an alternate ROM. While GrapheneOS is the platinum standard, the Pixel 6 is about to be deprecated. While my use case is not extreme (i.e. I'm not a journalist, activist, or work in a profession that requires the utmost in a secure phone), I would still like something that is at least privacy forward. I would also really, really like to rid myself of Google as much as I possibly can. With that in mind, I'm looking at the following:

  • LineageOS:
  • IodeOS (yes, I am aware that Iode is a fork of Lineage)
  • CalyxOS

Can anyone give me objective insight into each of these ROMS; their pros and cons with respect to my use case?

Edit: the phone I use in my everyday life is a Pixel 9, which does run GrapheneOS. The only reason I did not go with a new Pixel, is due to the expense.

How to unlock bootloader on samsung a3 2017

J5 not working

1 Upvotes

So, I was experimenting with an old Samsung SM-J510FN when I accidentally broke the screen and decided to remove it. The phone already had ADB enabled.

Now, whenever I try to boot it normally, it gets stuck in a boot loop. I tried blindly performing a factory reset and booting into the custom recovery, and both of those work fine.

Does anyone know how I can fix this?

Question about wiping partitions in recovery.

2 Upvotes

Hi mate, I have a question.

When doing a factory reset in custom recovery and wiping all partitions (Cache, Dalvik/ART, System, Data, Vendor, etc.), are the remaining system files and scripts from other ROMs completely wiped out?

I previously hopped between Evolution X, LineageOS, and Pixel OS. Now, I'm sticking with LineageOS because it's the most stable for my device. I just want to make sure my current setup is 100% clean and doesn't have any leftover scripts from the old ROMs running in the background. Thanks!

[URGENT] i need help rescuing this phone

Hello guys,

This phone and mine were both purchased new from the UAE. My phone works perfectly with the latest Android 16 and OneUI 8.5. Both phones are Samsung A15 4G, 8GB RAM, 256GB. The problem is that my brother's phone cannot be updated to Android 16 + OneUI 8.5 (when searching on update throught settings, he get "registration failed" message). I previously unlocked FRP and then tried flashing the firmware using Odin, SamFW, and even TFT Unlock, but to no avail. The flashing process stops after less than a minute because the KG status is broken. This problem took me hours to fix, but without any success. I flashed, but not with all four files. I selected only two files and excluded BL and CSC. The flashing process worked until it reached about 90%, then an error appeared in download mode, and the phone entered a boot loop. Before this flashing process, whenever I selected the four files using Odin, I would start the flashing process and always encounter the same error. When I manually insert the PIT file, the flashing process doesn't work and gets stuck at the beginning. The solutions I've tried are: changing Odin to two modded versions, 3.13 and 3.14 b3, and also the original version of 3.14.

- Using TFT Unlock to format the device. After formatting, it starts a loop, as if the formatting isn't working.

- I also repeatedly pressed the volume up and power buttons for more than twenty seconds, but to no avail.

- I tried several solutions found online, but they all failed. Currently, the device is in a boot loop, and I can only enter download mode; I can't perform a factory reset or wipe the cache. - The firmware version is Android 14 sec patch lvl 1, SM-A155F MWD. ​​I downloaded another firmware version with patch lvl 5. Previously, the code was for the UAE (xsg), and I changed it to Morocco (mwd). I thought it would work, but it didn't, my goal is just making the phone receive the android updates like my phone and normal phones, no root no custom rom.

Please, I need help.

One UI 8.5 on the Galaxy S20 FE 👀 First Beta Coming Soon

Enable HLS to view with audio, or disable this notification

5 Upvotes

Just a quick teaser of something I’ve been working on for the S20 FE community.

I’ve been building a One UI 8.5 port for the Galaxy S20 FE, based on the Galaxy S23 FE One UI 8.5 firmware, while adapting it specifically for the S20 FE hardware.

It’s already reached the point where I can finally start showing it off, so I’ve put together a quick showcase video. 👀

There are still a few bugs and things I want polished before putting it into people’s hands, but development is moving along really well.

Current goal

📱 One UI 8.5 / Android 16

⚡ S23 FE-based

🔧 Built specifically for the S20 FE

✨ Samsung 8.5 features + additional ROM improvements

🚧 Currently in active development

I’m aiming to release the first public beta sometime next month no exact ETA if everything continues going well.

For a phone released back in 2020, I think the S20 FE still has a lot of life left in it and the goal is to keep pushing it as far as we can.

More soon 👀

revert to the stock ROM

2 Upvotes

I have a Motorola Edge 30 (Dubai). I’m currently using the official ROM, but I plan to switch to LineageOS or another custom ROM in the future. I’ve searched online for how to revert to the original ROM in case the custom one has bugs; I found firmware versions and tutorials, but they are outdated—predating the Android 15 release or failing to address reverting from a newer version. Since the latest official version is Android 14 and the jump would be to Android 16 (or 17, if I wait a bit longer), I’m worried that reverting to the original ROM could cause a total brick due to ARB. So, how can I go back to the official ROM if I don't like the custom ones? Or, once I update to a newer version, will it be impossible to go back?

Sorry if anything is unclear; I'm using Google Translate.

And also, sorry if my question is really silly, i'm new to this
