Yep, I had installed the GAPPS-ICS package... With the procedure in link, my Market was worked ok.
Now, the other problem, it's a problem with HSDPA/EDGE conectivity: The cellphone shows the H (or E) symbol, but it rarely opens the data access to EDGE/UMTS network. Could have a workaround for this issue?
Remember that, however, the Wi-fi access works ok!
Recently i've installed the CM9 for E400, and worked successfully. But, I have some issues with this rom, as follow:
Radio FM missing (not exactly a issue, due the lack for support at this momment, I know =p);
The Google Play (Market), it's falling into ERROR 921, and I can't download any apps to my Android.
However, I have "googled" about error 921, and I've found some workarounds, like wipe cache, restart play application, and others, but, no one of these has worked. Have you a another solution for this problem?
Sorry for any inconveniece, I already solved the problem =):
