[ALPHA] [2014-10-29] [MT2-L05] TeamWin Recovery Project - Huawei Ascend Mate 2

TWRP Alpha build for MT2-L05(LianTong) TeamWin Recovery Project
Not working:
Could not handle Internal Storage properly, i.e., Wipe data will wipe internal storage as well.
Most of the text and even the config/build itself is copied from Modding.MyMind work on US version MT2L03. Thanks, Modding.MyMind
****ALPHA Version WARNING *** IMPORTANT *** MUST READ ****
Please note, due the structure of this phone storage, the Internal Storage (/storage/emulated/0 size 12GB) is actually shared with /data partition, and the mount point is /data/share, this is not same as google recommended value /data/media, and current TWRP code could not handle this properly. Also Modding.MyMind has PM'ed me that he probably will spend less and less time on XDA/development work, and I really lack of expertise/time on this one, so This build didn't resolve this issue. That's why I labeled this as ALPHA version.
Internal Storage /data/share /storage/emulated/0 size 12GB
External SDcard: /mnt/media_rw/sdcard1/ An SDCard is required to use this TWRP build and recommended 32GB or bigger.
For more information about this issue, please check TWRP article http://teamw.in/DataMedia, and please noted that it mentioned "A stock AOSP recovery would format data including the "sdcard" but TWRP will use its regular factory reset setup that leaves the internal storage intact" is not working in this TWRP alpha build., i.e., This TWRP will wipe your internal storage when you wipe data.
So, using this TWRP recovery, fact is:
. The backup target must select External Storage.
. Backup /data will include the internal storage, and this partition size will be ~12GB if uncompressed.
. Restore /data will override internal storage area.
. Wipe data (Factory Reset) will wipe internal storage as well.
Please read above carefully, and understand the risk of using this alpha build.
Recommended approach:
In your daily usage of the phone, try to save everything to external SDCard, or manually backup internal storage to external SDCard frequently.
When using TWRP, back/restore following partition is safe:
/boot
/recovery
/system
And always take caution when backup-restore /data, also, it is recommended check the compress option when do the /data backup.
Again, Many application may save files into Internal Storage including the pictures you taken, and files/songs you downloaded. So be aware of the risk of using this TWRP that may wipe the internal storage. If you are not clear/comfortable of this risk, please do not install this TWRP.
****ALPHA Version WARNING *** IMPORTANT *** MUST READ ****END****

Great work. If anyone could help finish this project off, I am more than happy to keep testing. If we can get this recovery fully working, then I think we would be far closer to understanding how to port kitkat to the MT2-L03 devices.

Yes, I do have an idea/workaround for this issue, and hopefully open this discussion thread can get more idea/evaluation going on.
The /data/share folder is treated as internal storage, but twrp is hard coded /data/media in many many places. So maybe we can rename 'share' to 'media' when boot into twrp, then rename back before reboot. But the 2nd part may not easy to guarantee. If it get into normal OS booting, it may cause confusion even damage.
So I am not like this workaround even myself.

disregard...

I think B606 breaks recovery. After I update to B606 and reinstall TWRP, it just hangs on splash screen every time I try to enter recovery.
