Hey man, I think you made a calculation error!

Try 2061853401311 instead, see if it works.

Diag mode or gucci

I think i have the exact model of redmi note 4g. Hm Note 1S CU (2014912)

Cant enter diag mode in any ways.

Did you managed to solve this?
[Redmi Note General] t.rosca25:
First connect your device to usb and disable MTP and enable usb debugging mode. Install Android SDK (developer.android.com/sdk/index.html) -> goto the folder where adb.exe is located (from command prompt) and type :

adb shell

su

setprop sys.usb.config diag,adb

Now the diagnostic mode is enabled .
[Redmi Note General] sabesisebas:
Still not working

Thanks for the help

I did this, but dont know if its a problem with the diag or a drivers one.

But QPST doesnt recognize the phone still.

Tried enabling and desablint mtp, debugging mode, etc.. but nothing appears in the qpst.

---------- Post added at 06:42 AM ---------- Previous post was at 06:20 AM ----------

Hi everyone, I have a Redmi note 4G single version.

I followed gkan's method and find my phone's original values is all same as gkan edited values, expect for code 06828.

so I only edit the code 06828, and its original value is 71.

In my country Taiwan, using the band 3/28 and band 8. and I only have the carrier card using band 3/28.

But band 3 is unlock originally.

Therefore, I don't know how to check the band 28 and 8 is unlock or not.

Also, on the Xiomi models, if one sim is dedicated to data LTE does the other sim stay at 4G for voice/text or does it drop to 2G only?

I own a Mi 4 lte, anybody know if I can use this method to unlock some lte bands? Have any of you here heard of someone successfully unlocking mi4's lte bands?

My phone support lte bands 1 / 3 and I'd like to unlock band 20 (800) and band 7 (2600mhz)

There's no hardware limitation as the snapdragon 801 does support these bands on multiples phones (galaxy s5, Xperia z3, HTC one...)

Thanks guys for any input, I prefer to hear about a success before trying. In the meantime I'll read thoroughly the topic but if you're aware of a successful bands unlocking for a mi4 do not hesitate to link me to as it would save me some precious time :)

[Redmi Note General] vkass:
I could swear I saw a thread on XDA for redmi 3 about unlocking band 20, at first he failed but then he just put the LTE string for all LTE bands and it worked, I can't find the thread anymore.

Looking at s7 bands it has Bands 18, 19 and 20 and they all say 800MHZ.

If anyone wants to try use the LTE string with all s7 bands and see what happens.
[Redmi Note General] vmarsi:
Folks,

LTE bands aren't something that can just be enabled with a software update. Enabling of a band requires a hardware radio frontend that is capable of tuning into that frequency band. The radio (RF) frontend downconverts the signal from whatever band it is tuned into, to baseband (or zero frequency), and passes it onto the modem for decoding. The modem doesn't care which frequency the original signal was at, and doesn't need to - it always works at baseband.

Now frontend RF radios come as chips that have tuners for multiple bands. These multi-band radios need to be told to tune into a particular band, and that instruction is generally provided by the modem. So that's the "software" that you're trying to modify. However, if the radio tuner for a particular band is not present, the radio is NOT going to be able to tune into that frequency no matter what the modem tells it to do. In fact, it'll probably be an invalid instruction to the RFIC and there's no telling what it will be interpreted as.

The Indian version of the Redmi Note 3 for example supports the following bands: B1 / B3 / B5 / B7 / B8 / B38 / B39 / B40 / B41. In all likelihood there is no tuner for B20. So no matter what software update you do to the modem, there is no RFIC that can tune into that band.
