[Q] Cube talk 5h no 2G or 3G network connection

Hi, I just bought a cube talk 5h, but I don't have either 2G or 3G connection. All the rest seems to work OK. Somehow it knows that the sim card is there because it is possible to access the SIM section in the "settings", but does not ask for pin and at some point endlessly tries to access sim details without getting it. Impossible to make phone calls or 3g connection, of course. I did "factory data reset" and "update system" but did not work. I tried to reinstall the firmware, so I downloaded the file A5300_V1.03_20130927.zip, uncompressed and painfully tried to decode the Chinese instructions, but when I tried to run the "Flash_tool.exe" file it does not work on my windows 8 laptop, gives the annoying error "access violation at address xxxx in module flash_tool.exe etc...".
So the questions are: 1) Is there anything else I could do to recover 2G and 3G network connection? 2) Could the problem be in the firmware? 3) If so, is there any simple way to reinstall it without using this Flash_tool.exe software? 4) If not how can I make this software run in my computer? Sorry for all these questions but I fell out of solutions, and I never before installed any firmware, so don't even know the basics...
Thank for any help in advance!

Solved!

Hi, I solved my problem, and I'll just put here the info to whom it may be of interest. In fact 2 problems occurred:
1) In my Cube Talk 5h (I don't know if it also happens with other Chinese manufacturers), the SIM card was not recognized until I removed the pin with another phone. Once the pin was removed (really removed and not only put to 0000!), I finally had 2G connection, but not 3G. If within the Cube I try to put again the pin, it will not be recognized anymore, so I guess there is no way to use a pin on this phone...
2) At that point I had 2G but not 3G, because the APN was not correctly set up, so I had to manually do it, and finally everything was OK.

[Q] SM-G900L Phone unable to use 4G in Australia?

As the the title suggests,
My dad's boss purchased this phone and while it works with any sim you place in it, upon turning the phone on, it basically summarises the following,
You have inserted a USIM that is not part of LG U+, and as such will be data locked.
(not word for word quote)
Now I take this to mean that the phone was carrier locked to Koreas LG U+, but the phone works here, and phone calls, and 3g speeds, but no 4G/LTE.
The current firmware version on it is 4.4.2 with I believe G900LKLU1AND3_G900LLUC1AND3_LUC
Now I've tried many different things to try and fix this;
I've read that 4.3+ version is bootlocked, (not exactly sure what this changes)'
I've tried flashing an Australian SM-G900I firmware (thinking the bands will be fixed, as its a software not hardware issue as far as I can tell)
Upon trying this, Odin throws a failed error, the download mode on the phone freezes, I can reboot it, and it's all good and dandy.
I then looked around and found that its possible to put in a SIM unlock code, however I query how that would work as the sim already works, just not LTE/4G
I tried Chainfires Region Unlocker (yes I know it said only tested on Note 3), which said succeeded, but actually did not enable 4G.
And I also saw a rumour that, if you place a phone call for 5+ minutes it will unlock said phone restrictions. In the phone logs it does show a phone call occurred previously before this phone was purchased, not sure if it was 5 minutes, but this may have been the case.
I'm stumped as to what can be done to flash this phone (or whatever can be done) in order to force it to allow the LTE/4G Networks,
Just to re-cap for the tl;dr,
4G/LTE not connecting as the phone mentions it restricts it due to being a NON-LG U+ SIM upon turning the phone on.
Please help ?

Hi
I also have g900L and had issue with LTE at the beginning But I resolved the issue by the following;
Please dial 319712358 and they will show you a box where you need to enter password then enter 0821.
This will lead you to the hidden menu page where you can find network mode where you can switch it to 4g mode.

I will pass this info on to the guy that owns this phone (my dad's boss) and hopefully all good,
Thanks man ,
Will post back here once I find out if it works on his phone.

Hi, just wanted to let people know I've had this same issue. Bought a G900L online and the network would connect to Optus' 4G/LTE for a few minutes at start up then will automatically go back to 3g. The solution above seems to have allowed my phone to lock to the 4g network.
Thanks

[Q] No data on Samsung Galaxy S5 Virgin Mobile(G900P)

So i recently flashed cyanogen mod 12.1 for my galaxy s5 ... Everything seems to be working well except for one major thing, that being mobile data...... there is a exclamation point in the Bar/Internet notification at the top, and I can't access anything on the web without using WiFi. This might be because I'm using the Sprint flash for my Virgin Mobile phone, but they are the same model G900P. I've tried in the mobile network setting changing the access point name to virgin mobile, but it still isn't working . I'm not sure if I should change any of these settings under the virgin mobile access point settings or what I should do. Please help someone before I resort back to stock Touch wiz

Did you do a full wipe and the dalvik also? If not, that might be the problem.

It's my understanding that although Virgin, Boost, Replublic, and Sprint all use the same network, the phones themselves aren't compatible with the other "carriers". It's interesting that regular telephony works, but this could be because you flashed the firmware, just like flashing phones from 10 years ago often worked. Sprint uses CDMA for telephony, so perhaps this is why this works, but data, which uses GSM, does not. It's also my understanding that the way Sprint determines network compatibility is by the ESN/IMEI. CDMA will also be part of the phone itself, whereas GSM info will be on the SIM card, so that might have something to do with it as well.
I'm doing a lot of guessing here, so take my "understanding" with the appropriate amount of salt grains.
Did everything work properly before you flashed CM?

I can change the carrier selection option under sprint to virgin mobile, but it still doesn't work... if that helps... and yeah, calls are fine but mobile data is a no no also yes everything else in the rom installed properly

No Sim card issue
Running Bliss pop 4 (cm12.1) on vmu g900p.
3g and telephony work out of the box but 4g does not. Lock screen says no Sim card. I have called virgin to verify that my Sim card number matches what they have on file. And searched low and high for solutions. Any idea?

Sorry to bring back a dead topic, but did you finally get a solution to your problem? I am facing the same thing with a g900p on RingPlus. (purchased from Freedompop) I managed to get data when i flash back to a the stock Sprint rom.

Can't get connection to ANY carrier

Hi! I'm having some mayor problems with my OnePlus One.
For some time I have had problems getting calls and sms when using 4G but it seemed to be a problem with my carrier but 2 weeks ago I dropped my phone and the screen broke so I bought a new screen and replaced it. After that the connection to my carrier dropped randomly and now after trying to fix it in different ways I can't get any connection at all with any carrier !
What I have tried so far:
Factory reset
Reinstalled CM
Put paper under the sim for tighter fit
Turned the radio off and on and restart phone
Change pin code
Replace sim-card
Tried different carriers on my phone (my simcard worked on other phones so it is the OPO that is the problem)
Total restore by fastboot-flashing
Installed OxigenOS 2
Tried all modems from the modem collection on CM and Oxigen.
Retyped the APN by hand
Opened the phone again and checked that all cables are connected well
Tried manualy connect to my carrier under Network Operators
For a short time of maximum 10 seconds I got a 4G connection twice in now 3 days of trying but then it stops working again. It feels like a hardware problem BUT I can see a lot of different carriers under Network Operators but when trying to connect it loads for ever and then says "Can't register to your carrier". I called my carrier and thay said nothing was wrong from their end and when I tried on other phones it worked flawlessly.
I'm really out of ideas now and I don't know where to go from here. I really hope someone of you knows that might be the problem!
Thank you so much!

If imei present you can try mobile phone exchange offer on flip kart like online stores. When this happened to my phone I did it , very easy.

Sometimes opo dont search available network or wont register on any network.
Sulution: go to access point and reset it to default first then go to network and try to search for network n if ur able to search then try ro register manually and if it does not work then go to dialer and dial *#*#4636#*#* then click phone info and select the lte/gsm ato prl mode and then click turn radio off and again tuen it onn then smsc refresh and update ( i dnt remember it correctly) if that dnt help then ur network antena is damaged

Cant connect to network or change network from "Global"

Device: G955U
Carrier: VZW
Starting Firmware: PartyCyborg Rom (Root)
Current Firmware: 5DSC1
So having a strange issue hoping someone can help me with.....
Woke up this morning phone was working, since my phone was charged I turned off "Battery Saver Mode" and after i did that I lost network connection. After checking that the network wasn't just down I began by flashing to stock flashing "3CRE2", thinking maybe something in the software no go.
Decided to apply the stock updates, I did this for awhile to no avail.
When I hit update 29 I think it is, the update right before the newest update, magic!!!! It started working and saw 4g LTE icon and had bars. Thinking that it was finally fixed I went ahead and installed the newest update which was pie thinking all was good. And yet again lost connection again.
Im getting "NO SIM CARD" on the lockscreen. Also, when I go to Network Mode I can't change from "Global" to "LTE/CDMA"
I went to Verizon got a new sim still no luck.
Any advice???
-------------------------------------------------------
-What is the dialer code or is there an app to force the network type to LTE/CDMA?
-Does anyone have a pit file for the v5 bootloader?
TLDR:; Cant get phone to connect to cell tower, says no sim card but got new sim card. Can't change the network settings from global to lte/cdma
