How To Guide [GSI][PHH] Guide & Support [Mojito][Sunny]

[ChristianWS]

Okay:

1. The difference would be minimal, only 3 pixels of difference, the reason it stood out before was because it was a really big difference.
2. The user spends more time looking at the device unlocked. Apps that don't have a seamlessly StatusBar and TopBar make it very clear the distance from notch top to screen top is different from notch bottom to StatusBar bottom.
3. ... How's the lock screen getting different results anyway? Can't you just change whatever the lock screen is using to make it match the unlocked status bar

i dont know if this correct thread to ask this,
so i'm not gonna talk about these phh gsi (?),

I'm curious and wanted to do some experiment with ported gsi (?) like nippongsi. But some of the system.img are 3gb above. And i cant flash above that, only 3gb below.

So I'm asking if it's possible to flash 3gb+ system.img on mojito? I just thought that newer phone might have bigger system space

Dynamic partitioning is not as bad as we think, we can extend system partition size easily without repartitioning the whole device.

For example take miui global recovery version ROM zip and ..

1- Open the ROM zip and extract dynamic_partitions_op_list and open it.
2- Edit "resize system_a" value for example put "resize system_a 4282639872" instead of 3282642432 in the attached screenshot.
3- Save and add the new dynamic_partitions_op_list to miui ROM zip.

After flashing the ROM system image size will be increased to 4.28 gb which is enough to flash any gsi/semi-gsi you want.

Ps: "resize system_a" value + "resize system_ext_a" value + "resize product_a" value + "resize vendor_a" value shouldn't overstep 8.5 gb ( 8.500.000.000 ) the limit of Super partition.

Nippon's GSIs are based on ErfanGSI Tools. They don't have required patches for all the devices. Every & then, you would face many issues with it. If you need to run a stable one, it's recommended to run phh patched GSIs.

So I'm asking if it's possible to flash 3gb+ system.img on mojito?

You can, if you remove product partition which is logical. Although you have to replace with a dummy placeholder product.img & it'll work just fine.

I just thought that newer phone might have bigger system space

Mojito actually does (4.5gigs per slot) which'll be 9gigs for complete super partition.

Well thanks for the information, I'm still new with this dynamic partiton. Also I'm not gonna use this gsi as a daily either, i just want to try these type of gsi. i also would rather using custom rom for daily or maybe someday trying phh gsi

But would that align with lockscreen, is the question.

Maybe the lock screen is ignoring the StatusBar Height and instead using the Notch info to try to figure out the Status Bar Height?

I've figured it out. Will rebuild overlay with 116px as you said by the weekend. I'm kinda busy now.

Oh, thanks, appreciate it.

Also, I've found some... bugs regarding the battery:

1. Not sure if I'm getting some Mandela effect going on, but Battery usage stats is only showing up Mobile Network, Screen and Idle
2. Battery Saver Mode couldn't get turned on automatically, I think it also rebooted when it got to that point, and I couldn't toggle it after it rebooted. It seems the bug went away?
3. Charging while the phone is turned off makes it get stuck at the booting screen. If I remember correctly, after the phone has a minimal of charge the charging screen comes from the ROM itself, no? I think something went wrong, and I don't know if all GSIs are this way, or an issue with LOS GSI, or just some random error I encountered.

btw, is this dynamic partition op list only available on miui? because i'm also thinking use oss vendor as a base for an alternative. But on custom rom i dont see any of it

 

[MPK99]

Don't worry about size constraints. Just follow my advice in #244.

Doesn't work for GSIs. Only stock vendor will work.

custom rom i dont see any of it

ROM builds compress images as payload.bin, not as dynpart op list.

Erm, I need a bit of clarification:

Andy released a new LineageOS update, AFAIK it is recommended to flash it using fastbootd.

However, "Fastboot reboot Fastboot" opens Fastbootd from TWRP. And I was under the impression that TWRP doesn't support flashing GSI ROMs due to something involving "logical partitions". Is that limitation only for TWRP main screen and TWRP's Fastbootd is fine?

 

[MPK99]

Fastbootd is a recovery thing. Not a bootloader component. TWRP has it, OFOX has it too.

I was under the impression that TWRP doesn't support flashing GSI ROMs due to something involving "logical partitions".

It does support (of course, through fastbootd via PC), but not directly from recovery manager itself.

Is that limitation only for TWRP main screen and TWRP's Fastbootd is fine?

fastbootd is specifically designed for dynamic partitions, to be managed through ADB tools. So right now, only through a pc. Whether you consider it a limitation, or a design flaw, is upto you.

I recently fastboot flash system the new version without problem

 

[Datrix00x]

Have any stable Android 13 GSI for our devices ?

Ofc. Refer to recommended GSIs section in OP.

Alright, I flashed it with no problems. I was just confused because I was under the impression TWRP couldn't flash dynamic partitions at all.

Anyway, the ROM now comes with the old overlay merged. One thing I noticed, but forgot to mention before is that the expanded quick settings screen is bigger than the screen when there's media playback. This doesn't appear to be normal:



You need to scroll this screen before being able to return to the notification screen

No prob. I'm a learner too. Didn't knew it until I bought a device with dynamic partitions.

That's caz I haven't made any pull requests on newer modifications. Will make one when enough changes been made. Until then, I'm free to share them manually on this thread.

Seems like a ROM issue. It's a system ui thing. Which GSI is it btw?

 

[ChristianWS]

LineageOS. Will see if other people mention that they have the same problem or not. I think it might be related to the notch and/or the space between the date and hour

Check the dpi. Default for mojito is 409.

 

[ChristianWS]

409 in this ROM is uncomfortably small

....I really shouldn't have messed up with DPI. Now I can't get it back to what it was cause I forgot to you know... remember it. That's my fault and I messed it up

EDIT: 390 seems to be the right amount
