I wanted to know if there is anyone working/willing to work on BCM21553 roms? I'm not an android dev but I researched about BCM21553 phones and I found some info regarding fixing the issues with CM ports of these devices:
- CM9 audio issue
these are commits developed by Conn(psyke83 +
) which solved audio routing in cm11 (Conn came up with them after Biel +
had stopped development of CM9 and I thought applying them to CM9 tree might solve the issue):
You'd better apply these step by step and compile for simpler debugging of potential compile errors.
- CM9/CM11 OMX codecs(Video Recording Issue might be an effect of this issue)
I did a research to find out similar phones to ours which have a working port of CM and I found Samsung Galaxy S II Plus +
which has the exact same GPU(VideoCore IV) and almost same Broadcom chipset(although not the exact BCM21553). I thought getting it's codec blobs(from here
) and applying the following patch might lead to working hardware codecs.
The patch: https://gist.github.com/pawitp/7945188
we might need reverting the following commit for the above to work: https://github.com/broadcomCM/androi...384945a89db330
- CM9 USB Tethering
The fix seems to be already in CM9 device tree but it didn't get compiled by biel!(CM9 device tree updated after the last BETA5 build)
- CM9/CM11 Torch
Again comparing with GS2 plus I came up with following potential solution:
