Fix for Chinese device lack of data/data problems.

I've owned 2 Chinese cheap Android devices now and both gave me a problem, so I am going to go out on a limb and say I'm not the only one. In fact I lie, I know I'm not the only one it plagues. The problem I get is that I don't get a data signal, I can make and receive calls and send and receive messages, It's just the data. Does this sound familiar to you? I searched high and low, through pages and pages of various language forums. So I've written this post to bring all my hours of searching together. The problem originates with my network. I'm in the UK and on Vodafone. They seem to be the only carrier in the UK that block the IMEI's that aren't the normal numbers, for example my UK devices all start with 35, but my Chinese devices start with 86. That's the problem.
There is 2 parts to my fix but you might not have to do both. Start with the first and see how you get on.
Fix 1
Go to settings > more... > Mobile Networks > then select the APN you are using, scroll down to the bottom and select Authentication, then select none. Make sure you save the APN. It might take effect pretty much immediately, but probably best to reboot.
Fix 2
This is a little harder but not to bad. Start by downloading an app from the market called Mobile Uncle. Once installed select IMEI backup. This will help if you incase you want/need to restore it.
Next select Engineer Mode > Engineer Mode (MTK) > scroll right to connectivity > CDS Information > Radio Information > Phone 1.

Click on the 'AT+' box to pull up the keyboard. Delete the + and it will show you some options click on 'AT+EGMR=1,7" ".
(I don't know how you choose your new IMEI, I never go that far into looking. I just chose a number from a device I don't use)
Type your new IMEI in between the speech marks and press SEND AT COMMAND. Wait a moment for confirmation then reboot your phone. If you want to need/want to do this for sim 2 then do the same process except when you select AT+, select AT+EGMR=1,10" " instead.
Fingers crossed your problems should be solved.

Agreed but do you mean that data won't sleep after this?

I understand the instructions: effectively you use the suggested app to access the apn settings of your phone. it shows that there is two different apn settings, and by setting them both to default will fix the data connection problems.
I tried this, however it has had no effect on my phone. tested extensively as I am in hospital just now and haven't been off my phone.
Vodafone UK, HTC one S S4, rooted with stock 4.0.4 android.
Easiest/quickest fix I've found is to change connection type to GSM only, then back to CDMA once the phone signal resets. bloody annoying though, surprised that there isn't a fix for this yet.

"Slot has been permanently blocked"

I flashed a custom ROM and the on first screen my device asked to insert the PIN code, then i tried more than two times and it showed "Slot has been permanently blocked". I could't make any phonecalls And when i flashed my stock ROM it works normal.
Do you know how to unlock the SIM slot?
Thank you very much.
Device: Blu vivo IV (Gionne s.5.5) chipset 6598
Custom ROM: Lolifox V6
---------------------------------
If you truly believe the device is stolen or has otherwise been acquired through illegitimate means, we can't help you - you should contact the authorities and have the seller investigated. Stealing is a crime and stolen IMEIs are blocked for that very reason.
If not, first check that the phone supports the network frequencies that your carrier uses wherever you are - not all phones support all bands, and not all carriers support all bands either.
If you can tell us the make and model of the phone, we can point you to a device-specific forum in case it's a general problem or issue with that phone model.
Beyond that, you can try to take up with the manufacturer of the phone or the carrier if it's a carrier-branded phone.
I once had to make numerous called to my carrier's support line because my new imported phone was somehow registered in my carrier's database as a completely different kind of device, so the system kept kicking me off the data plan."

My device was not stolen, i bought it recently, if you guys want i could post the photography of the box.
I live in BRAZIL (BLU IV) and i am trying to install a custom room for a device which's made for INDIA(GIONE s5.5), the device, it self, is the same, what changes its the "software".I saw a video on youtube that someone from USA installed the same custom ROM and didn't get any problem.
I am apologies for this good English sirs.

If you enter the wrong PIN more than three times, the "slot" gets blocked and you can't use your SIM to connect to the network anymore. Newly bought SIM cards come inside one bigger card on which your PUC is written on. For security purposes, SIM cards require this code to be entered if they get locked down.

Thanks for your help or hints!

What happens if you switch 4G data from sim 2 to sim 1? Will that other network indicates correctly then?

I think they removed it in latest update?
I used to see 4g icon even when connected to wifi now it disappear when on wifi.
So maybe they disabled one when the other is active.
Between which region you got?

It depends by region. Don't know why...
There is system setting in local.prop, so it can be changed if you have root and cust partition read/write.

Question Software Update disappeared

Unlocked variant from Samsung. I had a Software Update setting section. Soon after putting my Verizon SIM in the device the setting isn't there anymore.
Not sure how to fix or get the setting back. I can't check for new updates either

I have an unlocked variant (SM-F711U1) running a Verizon SIM and software updates option is right in the main settings menu

If you can't find it there, try going to Settings; About Phone; then on the bottom you should see "looking for something else?" And software update under it. Check the pic I've attached

This is all I have

Sorry for the late reply, but to me it almost seems like your phone didn't quite set itself to Verizon's configuration when you put your Verizon SIM card in. It's almost like it has no configuration for updating software PERIOD. This is very strange as even the unlocked version, while brand new, with no SIM ever put in should still show some form of a software update option when connected to internet.
The two suggestions I have are 1)
Use Google dialer set to default and dial code *#*#3747#*#* that will take you to a menu with three options and you want to tap on the "phone information" option and there will be a massive amount of information about your phones network configuration in there including stating that it is actively running on the Verizon network and successfully has the carrier provisioning info. (Disclaimer: I suggest not getting curious and manually changing settings in there when you don't know what you're doing because you can disable network bands and really end up having to factory reset your whole phone if you don't fully comprehend what you're changing) I'm just suggesting that you look visually to make sure of what I said above is what you see.
2nd)
If nothing else, pop your sim card out and go to settings, general management, reset and then tap the reset network info option and let your phone reset it's whole network configuration. If it doesn't reboot itself after then manually power the phone down, while powered down reinsert your Verizon SIM card and then power back up and give it a few minutes to get itself reconnected to Verizon's Network and after about 10 minutes I would reboot the phone again and see if anything has changed.

Spoiler: Also check this in about, status information, SIM status
You should see what you see in my picture when you click the spoiler link.
