Hi
I have MTK 6575, SAMSUNG GTi9500, JDQ39.I9500ZHUAMDE (cloned phone)
Everything is working fine but there is no 3g,
I have tried to select in Mobile uncle tools but, WCDMA and other frequencies are un selectable, even in secret menu. but as per vendor and its user manual, this is 3g enabled mobile,,,,, in chinaphone arena forum they have uploaded file modem.img to enable 3g for several mkt devices, i have replaced through Rom tool box, changed the permissions as instructions, rebooted but no 3g, even gsm gone,,, then i have reverted back to my original backed up modem img,, GSM /gprs is back but no 3g.
As per my knowledge all MTK 6575 devices are 3g enabled.
My phone is rooted,,,,,,,any solution ???????
Thanks

Hi everyone,
I've just recently acquired a Feiteng GT-N9300+ v2.
I've spend 2 days and already bricked the phone and restored it via the testpoint method, flashed cwm and rooted. But since the beginning i have a problem with the 3g. When i go to the engineering mode and i try to change to wcdma in the rat options it simply change back to gsm only.
I've checked other configs but everything seems ok.
The result it that i only have 2g.
I wonder if anyone with this phone or an mtk6577 has experienced this problem before?
PS: i have 3g network in the area and i have 3g with the same sim card on another phone.
PS2: In my area i think 3g operates as 2100mhz but from what i read the phone supports it.
Thanks in advance.
Hello everyone.
I have been searching for a solution for my problem for months but never found any.
My problem is that my phone cannot connect to 3g internet , i checked my apns , they are all right , only edge is working (wap).
when I go to the network settings and then mobile network , I try to change the network mode to GSM/WDCMA mode or WDCMA only mode but it just won't do it , it automatically goes back to gsm mode.
I opened mtk engeneering mode and went to the band mode settings , I find that only the gsm mode ( EGSM900 , GSM850) are checked , under it there is UMTS mode which contains the WDCMA but it has a grey color and I cannot tick it.
I also tried to change the modem.img file located in system/etc/firmware but it it won't let me as it says that the settings are read only
my modem.img file name is : modem_1_2g_n.img ( which aprooves what I'm saying 2g edge only)
I also tried to fool around with the Maui meta 3g tool but that was beyond my knowledge , it says that target load doesn't support 3g somthing like that.
Does my phone really support 3g ? I mean if there are settings It means that it does , and I don't think that it has only 2g because it's an s4 clone , I think that the problem is in the modem.img file , please help me , I really need this , I would have worked with edge only but for my carrier it only supports the 0.facebook , and I need internet on my phone.
I hope I have provided enough information. I will provide screen shots if needed.
Thank you in advance.
No answers :/
any experts here ??
My idea is try to put another modem named 1_wc_g.img inside the rom and reflash it ,but i dont know how to do that
Hello, friends
I'm still trying to port Lewa OS v6 kitkat from Coolpad F2 8675 (mtk6592 with lte+td-scdma modem) to my Thl 4400 (mtk6582 with wcdma modem only). For the last months we have some progress in this, but the trouble with modem is not completely solved for now. It works only in 2G networks both on sim1&sim2. :crying:
What we have done:
1. Putting all mount*.smali in services.jar from stok rom. This step fixes modem death after first reboot (coolpad has different partition structure).
2. Using all libs, binaries, modem firmware and mddb from stok rom (it really differ, there's 2-3 modem files in firmware and 2 files in mddb instead of only one in stok).
This steps makes cellular network partially working. But 3G is completely unworkable. If we insert sim of 3G-only provider (i.e. there's no 2G network), it search for network, register for about 3-5sec (we see it on signal level) and falls. If we insert sim with 2G support to 1st slot it can register in 2G network.
I think that we need to fix some modem-related code in mediatek frameworks. Where we should look for modem-related smali files?
I would be grateful for any help. Thank you.
