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.

Hi,
I have Samsung GT-P7300 (tab 8.9) which has been bought in USA. It supposed to be unlocked (at least that is written on the Amazon product page).
I live in the middle east, when I put local SIM card (it's well secured-in, I can hear the 'click') and navigate to
Settings -> Wireless & Networks -> Mobile Networks
I receive the following error message:
"Insert SIM card to access network services".
The device supports the following network:
2G Network GSM 850 / 900 / 1800 / 1900 3G Network HSDPA 850 / 900 / 1900 / 2100
But my mobile company supports
850/900/1800/1900 GSM 850/900/1900/2100 UMTS
I'll be glad to hear some ideas.
Thanks.
Have you tried to put your sim in another device to check if it's going online? The supported networks from your provider matches with the tab, so that shouldn't be the problem. I think if your tab is locked you should get a different message, then the one you are getting now. Are you sure the sim is o.k. and put in the right way? Do you have stock firmware or custom?
I had the same problem (here in peru), my issue was because there was not MODEM flashed in the tab.
What i did, was to go to samfirmware.com, download the apropiate MODEM.bin file and flash it via ODIN. After that, everybhing works ok.
You can check if there is a MODEM flashed by looking at the ABOUT section on the configuration panel on the tab.
If you dont have a clue about what is flashing, what is modem or what the hell i am talking about, write me a pm or post it here, so i can give you a brief explanation (i am no expert, but i can help a lilttle)
Thanks for your help, I already rooted my cell phone and flashed new ROM so I have some experience with advanced android stuff.
On which configuration file were u talking about: On the android settings or on Odin? Is you SIM cover not closing smoothly as well ? On my machine, tab 8.9, I need to force my SIM cover to be closed. Do I need to root my tablet first?
10x.
I had a similar problem with my p7500. A simple factory reset with the sim inserted while booting the first time after that helped.
Just tried, didn't help... Also tried Samsung firmware update - no success.
Thanks anyway.
Hopes to hear some more ideas.
My 3G (WCDMA) won't work on my iPhone 5 Thunderbird - MTK 6577. When I try to activate WCDMA I'm disconnected from the network. And shows this: /a/img90/5567/xdascreenshot2013033015.png

Hi everybody!
I'm using a SGS III SHV-E210S (Korean LTE) running the official 4.4.4 KitKat ROM. I have been able to connect to the 2G network in my country in Africa since I got this phone. However, all the mobile networks here changed to 3G a few weeks ago, and since I have been unable to connect to the data network.
The only way I have been able to have my data connection working is by changing the network mode in the Hidden Menu from default "LTE 850 Preferred" to "GSM ALL", but this only gives me access to the slower 2G connection. All other options show 3G but the phone has no Internet connection.
I thought maybe be it could be a baseband incompatibility issue in the stock 4.4.4 firmware? So I tried flashing the modem for 4.3 on to my phone but no success with that either. Is there any fix available for this problem?? Any links where I can get it as well will be highly appreciated.
Thanks in advance.
Peace
Hi, I downloaded and installed Lineage ROM, everything was working fine but I found that I was not able to send text messages (receiving messages was okay), I tried change values under test menu (*#*#4636#*#*) but problem persist.
I tried clean installation of new ROM (Aosp).
I tried install new firmware from:
https://forum.xda-developers.com/re.../firmware-xiaomi-redmi-note-5-5-plus-t3759683
And baseband from :
https://androidfilehost.com/?fid=746163614322262750
And finally, text messages are OK, unfortunately I am not able connect to 4G/ LTE networks now. Only 2G and 3G networks are working. LTE services were working without problem on original Miui and Lineage ROM.
Can someone try help me how solve it ? I would really appreciate any ideas.
Do you think this can help?

Thanks in advance and happy weekend
i have the same question! +1
I tried fresh install original MIUI ROM, but it did not help
http://en.miui.com/getrom-340.html?m=yes&mobile=2 .
LTE is not available still.
I did not try this method still: https://androidfilebox.com/app/redmi-5-plus-modem-firmware/
But I don't have another option I guess.
With LTE no Problems = https://forum.xda-developers.com/redmi-note-5/development/rom-omnirom-t3823189
Unfortunately LTE is not working on this ROM (Omni) for me too, but I expected it, because as I wrote I tried original MIUI as well. It's problem of wrong firmware, baseband, modem or something, because hard reset or flashing new rom don't fix it. Btw, this morning I was in big city in my country and my phone was able connect to LTE, but it was 1800 or 2100 MHz, which are available only in bigger cities. When I came back to home, it showing only H+ again. It seems my phone is not able to connect only to LTE on 800 MHz (B20) currently, which is most widespread LTE frequency in my country and this one is only available one in my location. And I was able connect to this network before. Unfortunately I don't know how I can bring it back.
Solved.
My friend share her .xqcn file with me (she has same phone) so I flashed modem file via QPST Flash Tool to my device. Xiaomi started receiving LTE in my location- B20 frequency band, unfortunatelly it was continuously connecting and disconnecting between "no signal" and 4G.
The next step was flash MIUI 10 Global Beta ROM 8.8.9 to my phone via Miflash. LTE seems be stable and fully working now.
