Can i unlock band5(850mhz) in my redmi 2 prime - Xiaomi Redmi 2 Questions & Answers

Plz guide me to to unlock band5 in redmi 2 prime in my location band 5 is selected but my phone doesn't have unlock band 5 thats why i am getting so poor Network coverage plz can anyone help me

i too need this question's answer as we knows QC SD410 supports 2100Mhz & 850Mhz also but not enabled in redmi 2.
i tried with the QXDM tool messing with the NV values
as Vodafone only supports band 1 (2100Mhz) & surprisingly Dazen 1 having same Soc gets the 4G network of Vodafone but in redmi 2 it shows only 3g .
I tried to copy the dazen 1 nv values but still no luck.
it needs some more stuff to unlock the bands & m pretty sure its possible but dont know how

[Q] note 3 n 9000 cdma suppot

i have note 3 n9000 with gsm band support ... is there a way that it can support cdma and lte 4g bands .... when i removed the battery the sim slot is of 4 pins that means it can suppot lte also but the phone only shows gsm/wcdma options. is there any way to modify this ?
Hi, I have a note 3 n900a lte which one I check
mm in theory the phone conect to lte 4g in mexico band 4b for telcel
you might check if the phone model supports 4g
you must a chip compatible with 4g for to network provider
could you check in service mode *#2263# which type of conection have the phone
and for last your phone must have been unlocked by the network provider
sorry for my bad english I used traductor ... :; XD

[GUIDE] Increase JIO speed

How to speed up jio connection?
I am posting pre configuration also as well as in case pre configuration not work you can try at your own hit and trial method.
Pre config -
I am not providing any downloadable files or content. This process needs root and volte supported roms. Custom lineage and its based roms still can have issue. It will work best on eui roms ( stock and customs) .
App need -
Net guru (free) - download
1. Download net guru app. And give root access . It will take some time for configuration.
2. Wait untill it shows LTE testing.
3. Now go to menu and select lock bands.
4. Now select LTE and select "B3 1800+" band.
5. Restart and. Enjoy new speed.
Reason to lock only this band -
Coverage + speed too.
Check speed by trai app.
If above method don't work then follow till 3rd step and now select 3 individual bands at which jio works and check your speed at individual bands and lock them at your most preferable band.
Details about bands:
Jio is using 3 LTE bands for 4G:
Band 3 (1800Mhz),
Band 5 (850Mhz)
and Band 40 (2300Mhz)
If LTE Bands are arranged according to services then
Best 4G coverage*: Band 5 > Band 3 > Band 40
Best 4G Speed*: Band 40 > Band 3 > Band 5
Average 4G speed*: Band 40 : 30mbps+Band 3 : 14mbps+Band 5 : 5mbps+
Extra -
1. After Deleting app band locking still works.
2. Restarting doesn't affect band locking.
3. Updating roms or changing also not affect band locking.
4. It's not necessary band 3 will give you more speed or coverage try according to your area. Mine is most suitable at B3.
Working - Sim - up. Working in Delhi, haryana and up.
Post your results.
Thank you bro
If you will use this trick then you both incoming and outgoing call will not work at the time of data connection ,you have to switch to flight mode to enable again

lock to a particular 4GLTE band #noroot

Hey guys. Can any one tell how to select a paricular LTE band (3 or 5 or 40) in asus zenphone max pro without root. Any secret code for that? Dont confuse band selection with network mode selection (2g/3g/4g). I saw solution for rooted phone. But i dnt want to root.

Can not be done without root - I am actually trying to discover exactly at what level band locking is done from so I can develop an app just for band locking on Qualcomm chips.
I do know that root is required because we have to interface with the chipset and access phone state as well as RIL manipulation and I think even the network constants.
I am very new to programming but have scoured the code for hours and hours and have a pretty good idea how the modem and os communicate in relation to frequency bands.
NSG is the only app that currently can lock a specific frequency.
You may be able to do it with qxdm. I used it to add lte lte bands on my old lg g2 so you should be able to lock an lte band. Just be careful while using it as u may overwrite/delete important nv values. Google for more details.

I use nsg for more than a year... And it's doing band locking job perfectly
I use NSG but it doesn't work flawlessly, it perfectly locks on band 3 and band 5 but can't lock band 40 on this device, all enforcing is cleared after some time after locking it to band 40. It is irritating because band 40 gives the best speed in jio.
Does anyone have any idea how to lock band 40 perfectly?

N900L Network Data Issues LTE GSM WCDMA no automatic switching

READ THE [UPDATE] DOWN BELOW
Many Note3 Korean Variant users also reported this case
https://forum.xda-developers.com/showthread.php?t=2484602&page=115
The problem is that, I can't connect to LTE without losing my Network Radio Service Connection. I can connect to E/G/3G/H/H+ and still have network service, so I can still make calls and text messages, but when I turn on my Mobile Data, when it tries to connect to LTE, suddenly my service gets diconnected and I can't make phone calls nor messages though I could still use the data. I've already tried 3 LTE-Capable SIMS but the issue still happens.
What I had in mind is that it might be because it is Carrier Locked since it is a Korean Variant, but the problem still persists even after flasing other custom roms (this includes Note 7 Port ROMS, LineageOS, Stock-Based ROMS).
I love my Note 3, I will do anything to keep it alive, but still this one problem keeps bugging me...
Why can't I use both LTE data connection and radio service connection simultaneously?
Is anyone out there knowledge and willing enough to help us Note 3 KV users with this issue? :crying:
[UPDATE]
I get it now, when a phone is using LTE it means its not connected to any Mobile Network Service, instead it is connected to Data Network Service, yet it should receive Phone calls and Messages but it means that the phone will disconnect to LTE and switch to GSM/WCDMA (E/G/H/3G/H+) to be able to recieve the incoming call or message. I've tried that with my friends' phones, The first phone is connected to Data and is using LTE and the other phone is trying to call the first phone. The moment I call the first phone, I noticed that the LTE icon dropped to H and then recieve the call, It only happened because the option selected on the "Network Mode" (under Settings/More Networks/Mobile Networks-->Network Mode) is [LTE/WCDMA/GSM auto connect] so that's how it works
But that doesn't happen to my phone, after turning off the Mobile Data (I was connected to LTE btw) my phone doesn't automatically connect to GSM nor WCDMA network, it just stay on LTE mode and I have to manually select the GSM/WCDMA option in order to get Network Service.
So my final question is Why doesn't my Note 3 automatically switches Network Mode?
Note 3
Model Number: N900L
Status: Rooted with Custom Note 7 Port ROM
Condition: Good, No History of Repair
Current Network: SMART Prepaid

No it doesn't, the problem is already there even before I rooted my device. Flashing stock lollipop rom on odin didn't help either

Please start to read about LTE technology and its frenquency bands.
Then find answers to these questions :
1- My SM-N900L is locked to use which frequency bands ?
2- Wich bands are in use in my actual location (country) ?
3- Is it possible to unlock more frequency bands for my N900L ?
i can provide more help if things remains not clear enough.
Good luck :good:

I tried searching the supported LTE bands of N900L but I can't find any sites that tell exactly what the N900L actually supports though I found out on this forum
https://www.frequencycheck.com/models/AZzWA/samsung-sm-n900s-galaxy-note-3-lte-a
1) A / P / T / V models are made exclusively for the US operator market and for no other people, as their indexes hint (A-AT & T / P-SPRINT / T-MOBILE / V-VERIZON). In Europe, mainly international versions are used - in the case of NOTE 3 - exclusively N9005, in Canada - its own carrier versions.
2) The models N900S / N900K / N900L are identical in the set of supported frequencies. If you rewind the topic on page 9, you will see screenshots of one of these models, which show the frequencies you are using, in one of the screens you will see the treasured frequency of LTE b7. I think that users of this topic can be trusted with respect to information in the topic, but no one has elected you the right to believe solely on the site www.frequencycheck.com.

I did try checking my phone on www.frequencycheck.com, N900L is not on the list..
https://www.frequencycheck.com/models/AZzWA/samsung-sm-n900s-galaxy-note-3-lte-a
N900S though shows that it supports Bands 3, 5, and 17.
I also look it up on wikipedia on where the SMART network (my current network) falls on the list of LTE frequency bands, and it shows that it is on Band 05 alongside with South Korean Networks LGU+ and SKT. The supported LTE bands on my country are Band 1, 3, 5, 7, 28 and 41
https://www.frequencycheck.com/countries/philippines
I searched for how to unlock all LTE frequency bands on N900L or Korean Variants or Note 3 but the only option that shows up is by accessing the Service Menu on Stock ROM and manually changing the values, which still didn't work for me.
According to my search, N900L is locked to :
LTE protocol : B1 (2100) and B5 (850)
LTE-A protocol : B3 (1800) and B7 (2600)
Now try to find the specific frequency band used by your carrier (he can't use all of the six available bands in Philippines), and activate it.
Wich stock firmware do you use when trying to access Service Mode ? It must be the LGU+ one.
And what code did you dial for the same purpose ?

When you said activate, you mean select the band to be used by the phone right?
- Yes, I used the LGU+ Lollipop Stock ROM
- I typed in the dialpad, *#0011# and changed the network preference to LTE ONLY.

I mean activate only the LTE's frquency band used by your carrier.
Check your PM.

I've already done that, but the problem with radio service network is still present, I can't make or receive any phones calls nor messages.
