I saw a lot of users with CA-201L or C811 here, but it is very hard to find information about CAL21 (Japanese version) of GzOne LTE.
While CA-201L and C811 is similar in hardware side, firmware update server of both variants are different. According to my analysis, CA-201L shares similar update infrastructure with Japanese variants. I tried to find Japanese rom dump to analyze their updater binary, but it is *very* hard to find rom dump (of any Japanese version). Amazon Japan and Yahoo Japan Auction lists CAL21 for about 45k~50k yen (about $500), which is too risky to do experiment on possible brick outside of Japan.
So, I appreciate any rom dump of Japanese variant.
