[DEV] LineageOS bring-up thread for Lenovo P2 [P2a42]

[wzedlare]

[13.01.207]I created device/kernel/vendor trees for Lenovo P2 (P2a42[kuntao_row] only).

Update[20.02.2017]:Work In Progress, just wait until it becomes bugless

How to install:
- Always make a nandroid backup before trying it.
- After making it make your wipes and install this zip.

Device Tree: https://github.com/Wzedlare/android_device_lenovo_p2a42
Kernel Source: https://github.com/Wzedlare/android_kernel_lenovo_msm8953
Vendor Blobs: https://github.com/Wzedlare/android_vendor_lenovo_p2a42

Rezerved.

You can pull the missing blobs/files from the stock ROM. Just use Superr's Kitchen to extract them. I contacted him and he has already added support for the chunk file extract for Lenovo.

Look at my github repo for the partition sizes or lookup the "Lenovo P2 is coming soon" thread for all partition information.

You actually don't need root to figure out the partition size.

I will fix the partition sizes but I'm not sure about blobs because they seem to be symlinked to firmware and persist partitions

If you want a mirror for the files, let me know.

Thanks, I think mega is good enough for now.

by Stock Rom i meant the "russian leak". Which i linked in post #3 in the TWRP thread.

As I said before, there are some files symlinked to other parts like firmware and persist.I can't pull them because I am not root.

I'm trying to install the zip but it gave a an error 7. Can I edit the updater-script and remove the first 2 rows or this can be a problem? I can also upload the files you are missing just tell me where can i find the msadp cause I can't find it..

I (also) need to wait for 10 days to get the OEM bootloader unlocked, after that i am glad to volunteer.

The rom doesn't boot. After the reboot from the recovery it goes into bootloader and if I force it to start after the lenovo logo the screen became black with a blue led and the phone vibrates for 3 sec.

That''s because the TWRP i build was made specifically for zip files containing the proper "ro.build.product=" like stock zip files and stock OTA files do. Allowing TWRP to be compatible with those files and prefenting "not so advanced" users from installing the wrong ROM.

You need to open up the zip file and change that information accordingly.

Meaning stock graphic blobs are not working with AOSP base.

Do you know how to fix that? I have everything of my computer and if you can tell me what files need to be changed I can try to fix it. Thanks

No! Everything that is in persist is actually just calibration data. Its called persist to "persist" between reboots.
Everything placed there comes from system.
For those files look in:
/system/etc/wifi/WCNSS_qcom_cfg.ini
/system/etc/firmware/wlan/prima/WCNSS_qcom_wlan_nv_lenovo.bin
./system/etc/firmware/wlan/prima/WCNSS_wlan_dictionary_lenovo.dat

just rename them properly for a bring-up.

Then I should change device name to p2a42 what about using msm8916 graphics blobs?

Just change/add the assert information properly. Like this:
https://github.com/Alberto97/android_device_motorola_addison/blob/cm-14.1/BoardConfig.mk#L40
if you like to add more simply seperate them by a ","

msm8916 works for up to the same generation like (msm8939)
but i don't know about generation change like msm8953 is.

Trying wont hurt, I will prepare a flashable fix for tester to try it.
