r1 - Custom ROM starter template - Huawei P9 EVA-L09 B136

[paulobrien]

Let's get some custom ROM tweaking going on for our P9s!

Ahead of my own MoDaCo Custom ROM for the P9, which is coming soon, I've created a custom ROM starter template for anyone who wants to have a go. It's a bit different.

Basically, this ROM template will let you create your own custom ROM VERY easily. Easier than ever before. All you have to do is...

• download my ROM template zip
• make the changes to the system of your phone just as you'd like them for your custom ROM
• run some commands on your device via ADB
• add the resulting files to the template zip

That's it! No messaging around with install scripts, no rebuilding anything complex, just mod - and go!

Preparation

ONLY if you are completing the process for the first time, you need to set up a file on your microSD card - so launch and ADB shell and type the following commands...

touch /sdcard/exclude
echo app > /sdcard/exclude
echo priv-app >> /sdcard/exclude

ROM build

Once you have your system up and running how you want it, and you're ready to distribute it (just the system and cust dirs mind, it won't pull the data dir, so your personal data is safe), reboot to recovery, launch an ADB shell and type the following commands:

mount /system
tar -X /sdcard/exclude -zcvpf /sdcard/system.therest.tar.gz /system/
tar -zcvpf /sdcard/system.apps.tar.gz /system/app /system/priv-app
mount /cust
tar -zcvpf /sdcard/cust.tar.gz /cust

You'll then end up with 3 new files on your SD card - system.apps.tar.gz (which is apps and priv-apps from system), system.therest.tar.gz (which, as the name suggests, is the rest of the system partition!) and cust.tar.gz with is the cust partition contents.

Update the template zip with these 3 files and that's it. It's ready to distribute for people to flash via TWRP! If you have updated the boot image, you'll need to replace that too, the easiest way is to do a TWRP backup then pull that file from the SD card and drop it into the template zip as boot.img. That's really it!

I hope this inspires a few people to start playing around with custom ROMs for the P9.. more cool things coming soon!

Oh and the all important template file...

NOTE: You should not flash a template ROM onto a different version base ROM. You should always ensure you have a stock dload ROM to restore to if needed. Use at your own risk!

Paulobrien strikes again! Once again top work, thanks. Excited to see what our skilled devs here can wring out for the great P9!

I hope to see this with eva L18C185

 

[bratfink]

Great to see you here Paul, it's been a while since our phone ownership has crossed paths. Looking forward to your work!

@paulobrien what would it take to get a "pure" Android ROM running on the P9? Don't know if I'm being clear here - what I'd like is something like a Nexus experience, on the P9, Android cleanly and not this EMUI wackiness.

What about eva-l19 ??

I hope there will be development by some genius here from XDA for a custom ROM with stock camera implanted that the outstanding photo by co-engineering with Lecia with its certified lens can sustain.

If not it seems losing the purpose to own P9 that marketing itself with Lecia.

But it's just my two cents.

I have a Chinese EVA-D00. All the CHinese stuff on it is driving me nuts. WOuld this ROM work on it, or are they not interchangeable? Mine is a dual sim model. Thanks

It didn't flash on my EVA-L10 (without root), but I'm guessing if you root your phone you would be able to flash the ROM, but no guarantees it will work, since it's a different hardware (single sim).

i think theres not to much changes between this models. Only kernel DualSIM and NFC are the clues to run on both models. im a rom dev, but i didnt get my device yet. The actual pricedrop is now a hint to get it soon.

EVA-L19

This is the first time i am trying to make a rom..I got a twrp backup of my phone (l-19) and renamed the boot.emmc.win to boot.img, replacing the boot.img in a zip. after following all the steps, i was able to get the final zip ready with the cust.tar.gz, system.apps.tar.gz and system.therest.tar.gz. After flashing it on my phone, it doesn't go past the boot screen..

when i was performing the steps, the mount step showed the usage of the command but i was able to generate the required files. attached screenshot.

any ideas what i am doing wrong..

 

[dkionline]

@paulobrien, does i need cust for every stock custom rom? Can i use this from b136 update.app?

 

[umair9001]

Tried putting the boot image from the update.app as well didn't work out.. @paulobrien any ideas?

 

[umair9001]

through using the following commands, i got the required files again. this time the phone boots to the huawei logo and then it reboots and goes back to the e-recovery.

mount -o ro,remount,ro /system
mount -o ro,remount,ro /cust

mount /system
tar -X /sdcard/exclude -zcvpf /sdcard/system.therest.tar.gz /system/
tar -zcvpf /sdcard/system.apps.tar.gz /system/app /system/priv-app
mount /cust
tar -zcvpf /sdcard/cust.tar.gz /cust

Quick question lads, can I still get OTA updates using Paul's method?

I've converted my AL00 to a EVA-L09

If the updater app is available, you might be able to get the required..but doing OTA won't be successful.

 

[umair9001]

@paulobrien please can you provide any help on this as i can't seem to get the phone booted.

if there are any other ways to create a rom, if someone can point me in the right direction

 

[dkionline]

@umair9001, without modifing boot.img the custom rom wont boot.

Guys, from where do I have to start to learn how to compile new custom ROM ? I'm seeing very young guys doing it (as Alberto97), compiling AOSP roms for some devices and I would like to start giving an hand to this community... thx

@paulobrien what would it take to get a "pure" Android ROM running on the P9? Don't know if I'm being clear here - what I'd like is something like a Nexus experience, on the P9, Android cleanly and not this EMUI wackiness.

Yes, yes, yes, a thousand times, yes. The P9 needs an AOSP ROM that is 100% EMUI-free. I would use that in a heartbeat, and even give up some premium features(fingerprint and camera) to get it.

I would also love to learn how to build one myself.
