Hi!

I have problem with Landvo L200. I bought this phone about 8 months ago, and it was working without problem. But for a few days ago it was hanging up on boot - it was showing only white screen with blue "LANDVO" logo. So I decided to reflash it using orignal ROM "ALPS.KK1.MP1.V2.10 – 1479M.S49B.A1.140913.KK1.MP1.V2.10.QHD.EN.8P64.COM.COCLK – KOT49H – V1_WCDMA" and SP Flash Tool. Some data was downloaded but after a while (maybe 1-2 minutes) the program displayed an error message "S_FT_DOWNLOAD_FAIL (4008)" and "Download to flash fail!". The problem still occur.

EMMC Pattern Test(0x5A5A):

At the end of the memory test it shows "BROM ERROR: S_FT_MEMORY_TEST_FAIL (4048)"

Right now:

- it does not boot up

- I cannot go into recovery menu

- keeps showing the battery image when I connect the charger, but the image does not fills up - it looks like the battery cannot be charged

What can I do with it?
