A friend of mine did something stupid and tried to install a CWM-recovery for his MT6589 (model: AT-AS50SE) and killed his baseband in the proces. No backups are available and both the Serial Number, baseband and IMEI say unknown. Basicly I think his NVRAM is fried and restoring the correct IMEI information on Android level doesn't work because of the broken baseband.

The device looks like a probable iOcean X7 Elite clone, but I haven't been able to find any roms with this baseband version and the original ROM is not available (the company hasn't responded yet). Also, I'm not able to use any of the tools (SN Write Tool, Maui META 3G, IMEI & SN Writer) because it won't go into META mode (because of the broken recovery mode, I can't go into recovery mode anymore) or because I don't have the correct Modem and AP database.

Can anybody provide me a backup of their AT-AS50SE or a compatible device so I can restore the baseband? Or does anybody have an other idea how to restore the baseband on this MT6589?

I think you might try to flash the baseband from another MT6589 device and then use Mobileuncle MTK Tools to restore the IMEI.
Searching on google for that baseband I found this:


I have also star x920. On MTKDroid tools it shows info ..
Hardware : MT6589
Model : e2001_v89_zlh_hd
Build number : e2001_v89_zlh_hd_20130321
Build date UTC : 20130321-082621
Android v : 4.2.1
Baseband v: MOLY.WR8.W1248.MD.WG.MP.V6.P1, 2013/02/27 19:53

I have a ZP980 and I know in some roms the baseband is taken from other mtk phones.

According to my searches, it's not possible to really flash a baseband on an MT6589 beside then replacing the modem.img and/or rewriting the NVRAM through the tools I mentioned earlier. I can't get into META mode and I tried several modem.img files.

Formatting the NVRAM and soft-replacing the IMEI through MobileUncle MTK Tools didn't work as well.

I guess that waiting for the original company to provide the files.
