Hi there,
About a half year ago i got my Jiayu G4S, 16gb, octacore. Works great, but it comes with stock Android 4.2.2.
So a few weeks ago i decided to update the G4S with the official Android 4.4.2 Jiayu G4S update rom I found on needrom.com.
So i flashed it and booted the G4S, everything works fine, except for the mobile network.
I can't call anymore and the G4S won't connect to a my mobile-phone provider...
It shows some mobile network signal from now and then but that's it.
Could it be possible that the phone is on an different network setting or something, that it might switched from Europe to China?
I tried a lot of thing, with a lot of different roms, but i just won't work anymore.
Am i the only one wit h this problem? I've searched the internet for weeks now, but without any luck so far.
Kind regards,
Dicky
Hi .. I recently bought lg v10 h961n dual sim.. But the signal when Im at home is very weak the bars are 1 or 2 .. Outside is full I dont know whats the problem exactly .. Can anyone help me ? “there is no problem on sim cards and my home always have full signal service on other phones”
mine has that problem too, every signal in lg v10 is weak such as wifi,IR blaster and cell. idk thats not happened on G versions,
If the custom roms can help which one better c roms ? i'm on nougat v10 h961n
Hello
I recently purchased this phone for a family member. We set it up yesterday, and found that the sim card from their old phone that we've inserted isn't capable of allowing the phone to make/receive texts/calls. It just says something along the lines of "Can't connect to mobile network", despite showing signal bars. When I checked the connectivity bands against the mobile network's, it appeared that the phone should at least support 2G & 3G. I'm in the UK and haven't modified the ROM.
Has anyone had this issue before, and does anyone know of a fix? I've heard that some of the newer official ROMs are better for connectivity, but I don't want to flash the phone and void its warranty if the fault lies with the phone.
Many thanks
Luke
Heyyo, hmm can you please provide more information?
Link to the exact product purchased
What country and network is being used?
Does your device say x820, x821, x822 or x829 on the back of it? If not does it say what it is in the settings > about phone menu?
Can you please specify which version of EUI ROM it is running? Should be in Settings > About Phone.
As for upgrading EUI ROM versions? That will not void warranty as long as you don't have the x829 with EUI ROM 5.8.016s.... which is what I had and x829 with 5.8.016s is garbage. So many darn problems with it and has software updates disabled even via recovery update.zip... I didn't stay on it long since LineageOS 13.0 at the time officially came to the x2 heh

Thanks for your reply
This is where I ordered it from: LeTV LeEco Le Max 2 X820 5.7 inch 4GB RAM 32GB ROM Snapdragon 820 Quad core 4G Smartphone
I live in the UK and the phone's using a Tesco Mobile SIM
The device is the X820
I don't have the phone with me right now, but I believe the EUI is 18s
I wasn't aware upgrading the ROM version didn't affect the warranty, that's nice to know
Hallo,
I believe I might have the same problem with the mobile network. In my case, I am quite certain that the battery is the problem. I got the phone some weeks ago, but I assume it was laying around for quite some time, which might be not very beneficial for the battery? Anyway, the voltage should be 4.4 V after loading and as long as the voltage stays above about 4 V, I have good data connection. But after a while, the voltage drops below 4 V and I do not have any connection anymore, despite showing all signal bars! Is it possible, that you see a similar behavior with your phone? If you load it on a charger, does your data work?

I personally do not experience this but I'm 100% sure that the voltage from the battery should stay around 4V. If this happens try turning on the battery saver and dimmer your screen so you can spread the battery load. Maybe it will work idk.

You are probably right in saying that the voltage should stay around 4 V. This is probably the case for new or at least well aged batteries. However, that seems not to be the case of my battery. According to the App that reads out the voltage, it sometimes drops to values as low as 3.6 V. Sometimes, the voltage recovers a bit, but typically, not enough to enable data connection, for which I believe to need at least around 4 V to work (reliably!).

Thanks for replying, and sorry for my late reply.
I've tried making calls with the battery at full charge, but I get the same result. It's really peculiar...

I purchased a X820 from China (TomTop.com) and the junk had an EXTREMELY LOW signal.I NEVER received network signal at home.I have to go near a cell tower to get signal,as soon i drive away from the tower (around 5 blocks)i lost signal and could not make or receive calls..Remember that the company LeEco went out of business and the phones we buy today are NOT made by LeEco but are made by many private factories in China and in reality are cheap clones.I send the junk back and purchased a X829.Now i have very good signal and connection never dropsJust return your phone is defective..Here is a video i had to send to tomtop.com in order to get a refund.

I have exactly the same problem when the phone's battery level goes around 70% (~4v).
i.e. when battery drops below 70%, the network signal shows LTE with around 3 bars but there's no network connectivity and can't make/receive phone call. But as soon as I plug in the charger, everything works perfectly! This happens on all ROMs.
I wish there is a solution for this.
same problem for me .....

I believe your phone is a X829. Someone installed the X820 firmware to sell it easier. It doesn't have Band 20 for 4G. Tesco mobile is working on O2 network and they're using Band 20 for 4G network. Despite that it should work on 3G. In my opinion you should install a custom ROM and check things there...

Ended up just being too frustrating, so we returned it for a refund & bought a different phone instead...
It's a shame, aside from that one issue it seemed to be a great phone, especially for the price

Dear friends,
I recently bought an S9 Plus dual sim, SM-965F in my home country(Pakistan). Then I moved to U.K and bought Three 3 mobile sim. The sim works fine but there are issues with it.
First, Network signals are always low. I hardly get 1 to 2 bars. Only in center of towns it's 3 bars but still not full signal.
Second, when I install U.K based applications e.g, Three mobile app or Just eat, it keeps telling me that facility is not available in your county. Every app still thinks it's in Pakistan. I tried to change in Playstore, Accounts but not able to change country.
Third, the battery is draining like hell. Within 6 hrs I am dead from 100%. It bever happened like this in Pakistan but happening in U.K. I feel there is incompatibility issue.
Can anyone guide me, what should I do? I am thinking of flashing European firmware. Does anyone know compatible EU firmware which I can flash on this phone? Its unlocked and Dual Sim.
I have attached picture of my phones software info.
Please guide me further. Thank you
