Hello,
I am trying to find out the way in which I can able to activate the "Service Menu" or Engineering Mode" for LYF Wind 4, Handset from Reliance Jio, supporting LTE. I need this to change the LTE band to Band 40, which might result in better DL/UL speed for Jio, as the speed presently is really poor, under the "Welcome Plan".
Any Suggestions?

Greetings, my Iproi9350 marked q10 refuses to register with UMTS in Europe (EDGE works all right). i rooted the piece, and I accessed test mode through *#*#4636#*#* The test menu provides plenty of options on how to access the network. but the band selection is limited to: auto | USA | AUS2. The telephone is advertised to have the 2100 WCDMA band. I enquired the manufacturer and the seller. The seller answered they would contact the manufacturer. The manufacturer has never answered my enquiry and I suppose the seller has received none either. Any tricks or hints? I have Parkinson disease and I am unable to use a smartphone without a keyboard. I also need a dual sim one, and this handset is the best compromise I found so far.
Many thanks in advance
Please post your query in Android Q&A, Help & Troubleshooting
It seems like the phone has been locked to specific networks you have listed. You may wish to contact the seller to see how it can be unlocked.
I am a field tech and work with Sprint signal mostly. The S5 will camp on band 41 ( 2.5) not allowing me to see the other 2 LTE bands. Trying to analyse the LTE signal for in building is getting almost impossible since they have not released an amp for 2.5 and in florida thats what i mostly see in metro areas. I am using an S5 and need to know if there is a way to lock the phone onto an LTE band and then unlock it

I brought back a Pro 2 F350L from Korea because it was listed in swappa as the Att device unlocked. I took it to T-Mobile put in a sim card which automatically chose the appropriate apns. I only get 3g no lte. I have scoured the web and these forums but cant find the info that tells me wether i got the wrong device for Tmo bands. I need help either configuring the correct bands or correct radio to flash or if this device won't or can't get lte on Tmo network. I am more than happy to reward the parties or person who helps me figure out this problem. If i have the wrong phone then so be it i will get the other model (that gets tmo lte) and unload this F350L. Thanks for any and all help.
In network mode, do you have GSM/WCDMA/LTA auto to select, or just GSM/WCDMA auto?

Looks like you have the wrong phone ... https://support.t-mobile.com/message/435224#435224
Bottom line, for optimal utility a T-Mobile phone needs to be:
1. Quad-band GSM
2. HSPA+ on at least band 2, band 4 & band 1 (2100) for roaming.
3. LTE on bands 1, 2, 4 & 12.

So seeing the bands I posted would the phone work for ATT? Thats a huge question because it (350L) is posted on Swappa a a ATT phone? At least I can unload it there, LOL.

"AT&T 4G HSPA and HSPA+ use 850Mhz(Band 5) and 1900Mhz(Band 2) bands but it all depends on area if they own a license. LTE uses Band 17(700Mhz), Band 5(850Mhz), Band 2(1900Mhz), Band 4(1700/2100Mhz) currently."

So the F350S works on ATT and here are Your Phones Bands (as listed here on XDA)
LG F350S
WCDMA - 2100/1900/850, GSM - 900/850/1800/1900 MHz, LTE - 1/5/3/7/17
So will these Bands work with T-Mobile? I really love this device and I am totally hooked on the 5.9 inch screens color so I am hoping your ATT Model (The one your using) will work on T-Mobile? If it does I am more than happy to send you a few duckets

wiseguyy, I believe the phone must have band 2 and/or 4 for it to utilize TMO's LTE service. From what I've read, band 1 is used only for roaming. Read the entire thread you quoted above.

Hey guys,
I'm really interested in picking up a 4c, and would be even more inclined to do so if LTE bands can be unlocked (Ideally bands 2, 4 and 12).
This has been done successfully in the past on Xiaomi devices (specifically the Mi Note Pro with the Snapdragon 810). Since the 808 shares a very similar architecture to the 810, I'm hoping it can be done on the 4c successfully.
Here are some resources and guides to start with:
http://forum.xda-developers.com/redmi-note/general/unlock-lte-bands-step-step-xiaomi-mi-t3084774
http://en.miui.com/thread-154862-1-1.html

http://forum.xda-developers.com/oneplus-one/general/guide-unlock-aditional-bands-qualcomm-t2877031
http://www.xda-developers.com/remove-band-restrictions-qualcomm/
Hopefully someone with a Mi 4c is able to try and confirm their success!
That's very interesting! I wish also band 20 (800 MHz) could be unlocked since it's largely used in Europe.
Mee too interested to unlock (if possibile) 800 mhz
One more interested in the 800. :good:

Im up for B4 (AWS) :good:
doesn't have it unlocked but it seems it makes really no difference. Don't trust the few articles from people who did not even test...

It depends a lot on what network you're on. The LTE bands that come enabled by default on the 4C don't support any US networks.
800 mhz (band 20) would be great
What LTE bands does mi4c support?
Does anyone know what LTE Bands the Xiaomi mi4c supports out of the box?
Been struggling to find a reliable source/list

2G GSM 850/900/1800/1900MHz; CDMA BC0/BC1

4G FDD-LTE: 1800/2100/2600MHz; TDD-LTE: Bands 38(TD 2600) / 39(TD 1900) / 40(TD 2300) / 41(TD 2500)
800MHz?
Hi,
Bought mi4c to find out that I can't get LTE working in my village
I live 12kilometers from a bigger city. There is LTE available in my village but I think they operate on 800MHz and in city at 1,6GHz.
I dreamed about using my new 4g connection here after 3years with Galaxy S3
I have to try these guides. Thank you for providing them.
Regards,
Noboby tried to unluck bands?
Wouldn't advise in case it bricks the phone. If there is a way to unbrick, then go for it it

In Snapdragon phones there is always a way to unbrick but it could be very frustrating and time intense
I have tested it on many of my snapdragon phones.
On some phones, it works flawlessly. On other, the signal strength is weaken but works nevertheless. However, some phones especially carrier ones have anti tampering mechanism which reverts the value back to original after restart. However, usually this is solved by a custom kernel and custom rom but then again, it gets really tough to get into diag mode in custom modes.
Never had any problems.
But you MUST backup your EFS partition via recovery or using QPST / QXDM else you would have a lot of problems if you messed up the values like no signals or broken wifi or sensors etc. and SAVE them on your phone as well as on your PC. (at least two backups)
As long as you take the above two precautions, you will never mess up your phone!
Its supports LTE band 3 and 7 which is mostly used in europe, middle east and asia. However even after you select "Prefer LTE" from the setting it might not connect.
You can try this (this will change on reboot so will try to see if i can change within the code):
1. Enter *#*#4636#*#* in the diapad.
2. Select phone information 1 (there are two sims so select the first one)
3. Change to LTE/WCDMA (if it doesn't connect to LTE then try "LTE only" and then change it to LTE/WCMDA)
If the above doesn't connect to LTE then your carrier is offering LTE at a different frequency.
For me atleast the default APN were wrong, so i had to manually change the APN restart and then do the dialer thing.

There is NO LTE/WCDMA option only. Please see screenshot and point out what option I'm supposed to pick
screen shot of "phone information 1" --> http://imgur.com/BELHKaO
Which one of those am I supposed to tap on?
I picked "TD-SCDMA, WCDMA and LTE" but that broke network connectivity.
EDIT: Please also take a look at this: http://imgur.com/gallery/yzIHD49
I am currently connected to "3 ITA 3G" and would like to connect to "3 ITA 4G" but tapping on that makes a pop up appear "Registered on network". However no 4G appears in the bar on top. It remains stuck in 3G or H+.
3 ITA doesn't have LTE on band 20 [8oo Mhz LTE].
So why aren't I picking up 4G?
@AndrewIT im not in italy, however from Wiki it seems your carrier supports 4G on band 3 (1800).
select the "3 ITA 4G", then follow my steps. You have to scroll up that list in screenshot http://imgur.com/BELHKaO and you'll see "LTE only" and "LTE/WCDMA" option.

Thank you! I was finally able to see the 4G icon on my Mi4c.
Entered *#*#4636#*#* in the diapad.
Selected phone information 1 (there are two sims so select the first one)
I scrolled up [see screenshot] and set WCDMA and LTE from the list.

You can see that I successfully picked up 4G signal, but it was extremely poor, only one bar standing close to a window.
As I move inside the house it loses 4G and gets back to 3G or H+.
It seems that I'm way too far from the LTE antenna to get a good 4G signal.
Guys I am kinda lost here, so is there a good chance that it supports especially 800Mhz band or not ? And when I am here, is there hardware difference between TDD-LTE and FDD-LTE version? How do I find out which one I have ?
Q : Is it possible to activate, do coding, install or flash the phone to obtain Full range of 5G LTE 3G bands on this device for EU ? It was bought from Japan and it's set for this market.
I don't know wehere to start, it's a very good device and I'm well used to it, but I live in rural area where LTE band 20 is dominant, lack of it causing a lot of problems while on the move.
Any ideas ?
