The most likely reason for the Mi Note2 CN not working with the Mi Note2 Global settings could be the addressing for the MIDI interface, which uses the Board ID as part of the system address. This cannot be changed in the NVRAM.

For the IMEI, it should be in NVRAM550. To find it in a hex editor like UltraEdit, you need to monkey the bits of the IMEI into the Qualcomm format, i.e. little-ENDIAN. to change it, reverse the order of the hex-bit pairs, i.e 862033031416078 will be listed as 08 8A 26 30 03 13 14 06 87 - note the addition of a leading 0 before the first 8, and the insertion of 8A as the second hex group.

Have sent you a PM (with my e-mail), so you can send me an e-mail with the two NVRAM files.

Cheers,

GM.
[Xiaomi Mi 5 Guides, News, & Discussion] supercowz:
thanks for your reply, for the Imei yes i know how to find it usually, i done that on fews qualcomm devices

but with note 2 nvram i'mn not able to find them cant find 08 8A XX XX entry with hex editor

i just send you a email with both nvram, please dont share it until we found to remove Imei ....

edit : i found them ! :) small mistake on my side .... imei from CN to global are different, that was my mistake, since my friend from global didnt gave me his Imei, that's why i had trouble to find it on global nvram, with mine now easy to find ...

now another question is when if flash global Nvram or EFS (twrp backup) on my CN, simcard are not working and no signal, i understand why, but Imei still the same not changed ... do you know why ?

[Xiaomi Mi 5 Guides, News, & Discussion] greasymonkey1960:
If I understand correctly, there is some "locks" relating to the ESN when flashing - in the Qualcomm tools you need to tick a box to enable "over-ride" of the ESN check feature. This may be the reason, i.e. there is a different ESN and the lock has not been released, so the file is rejected.

You are still a long way behind me in the count of "silly mistakes" made :D

Cheers,

GM.
[Xiaomi Mi 5 Guides, News, & Discussion] supercowz:
yeah i understand :)

but when i flash efs from global under TWRP, this should not be involve right ?

u right im still noob on that filed, try to learn :)

what do you think i should do/learn to try to enable all bands on CN version like the global one ?

and thanks for you help and your sharing knowledge
[Xiaomi Mi 5 Guides, News, & Discussion] greasymonkey1960:
I am not sure. TWRP interfaces and interactions is not something I know about.

I would assume if TWRP has Super-User privileges, it may over-ride the lock, but I can imagine that the lock may require a "positive unlock bit", and if TWRP does not supply that, it will remain locked.

This is normal for hardware protection systems, and I assume that Qualcomm would use such systems.
[Xiaomi Mi 5 Guides, News, & Discussion] iHack13:
This is basically the same like the Yotaphones.

People flash global rom on the chinese version and depending on the checkboxes they have checked they end up with a working global rom without extra bands or no signal at all.

There is something that interfers with the EFS partition as greasy said. And afaik those are device specific and you cant flash them on another phone. They are only used as a backup , in case you do something wrong and have no more imei.

I vaguely remember those boxes in the old days that could flash imei to a spare board. Maybe qualcomm has that kind of stuff too. I never read into that stuff tho.

My guts tell me that we have to drill . Lmao (xbox users understood this joke)

Hi, my friend has a redmi note3. He can connect to giffgaff(UK operator using b20). According to https://www.frequencycheck.com/mode...redmi-note-3-pro-dual-sim-td-lte-16gb-2015116 , this phone supports b20. I wonder if this information might be helpful. I thought both redmi note3 and mi 5s support 18 bands, it could be easier to port band program than mi note2 with 37bands? I know note2 use 821 CPU, which is closer to mi5& 5s, and it could depend on the signal chip
[Xiaomi Mi 5 Guides, News, & Discussion] bisato:
This has already been discussed in the Redmi Note 3 Forum.

There are two versions of the Snapdragon Redmi Note 3. The Kenzo, without B20 and the Kate with B20, which is slightly greater.

And some user tried to flash the Kate-Firmware to the Kenzo and had no success with enabling b20.

Please try this:

From your friend with global Mi Note 2, have them take a backup using dd within TWRP, of the modemst1, modemst2, and fsg partitions. Then, (of course after taking a backup of these) try restoring them using dd on your phone, and see if it works.

One other thing to try, have you friend using QPST to take backup QCN file. Then, go to TWRP and use dd if=/dev/zero of=(modemst1 partition) for example, to clear modemst1, modemst2, and fsg partitions. Then, boot up phone and enable diag mode and flash the qcn file from your friend.

Hello all, I need help here. I am mi5 user with stable global rom 8.1.2.0 and already unlocked my bootloader, fully rooted my device and sucessfully changed my NV value to 2061752272095. I edited the NV value so that I can use band5 which are used by my telco. I can see Band 5 now on my network signal guru app in Band Locking but during the testing my phone didn't detect Band 5 signal. Can someone help me what should i do to force my phone to use lte band 5.

Thanks in advance

[Xiaomi Mi 5 Guides, News, & Discussion] bobanbg:
Is it possible that last MIUI Global (7.2.9) has enabled b20?

I received LTE signal in my village that is covered only by b20.

It's possible that Vodafone implemented other bands but maybe somebody that has root can confirm.

I attach my baseband version
[Xiaomi Mi 5 Guides, News, & Discussion] forgivemypoorEN:
You might be right!

I have mi 5s. I was using giffgaff (UK virtual operator which uses O2's network), it used to have only 1800mhz. I put it on sim2, which only had 3g. I could search O2's 4g network with sim card1, and I thought that was because O2 allowed 1800mhz, but was not open to giffgaff. I just tried to put it on sim1, and I got 4g!

Briefly, it shouldn't be a concidence that our operator opened 1800mhz the same time, only if they think it should be done on Chinese new year :).

By the way, do I need root to check which band is used? I'll check right away.
[Xiaomi Mi 5 Guides, News, & Discussion] bobanbg:
[MENTION=5652060]forgivemypoorEN[/MENTION] you can check bands with a app called "network signal guru". If you have root you can check which bands are you connected with
[Xiaomi Mi 5 Guides, News, & Discussion] forgivemypoorEN:
I tried, but it only shows the band I'm using, does it always show all the bands that I can connect? Maybe I need to move to another area. By the way, does the test cost my data flow? I stop buying any data pack from my old operator, so I don't have a data pack (like 500m) and each mb of data costs 3 pence.
[Xiaomi Mi 5 Guides, News, & Discussion] forgivemypoorEN:
Sorry everyone, it turns out that my operator did roll out b3 (1800mhz), no b20 was detected.

Hello Guys !!

Thanks for all the work you've already done !

I've seen in previous pages that B28 is unlockable, but I've not seen a tutorial about that.

Can you confirm that B28 is unlockable for MI5? Can someone who unlocked this band (700mhz) make a step by step tutorial please ?

Mi5 = Mi5 with standard official Chinese rom.

Some stores sell an Mi5 Global/International version, this is just the Mi5 with the standard official global rom from xiaomi.

But be careful some online stores sell an Mi5 Global/International version (still normal/regular Mi5) but they ship it with their own custom version of the global rom!

In short Mi5 Global/International = Mi5 with multi-language rom :)
[Xiaomi Mi 5 Guides, News, & Discussion] witek_77:
yes. This is the same hardware but oficial CLEAN global stable ROM and EU plug and instruction in polish/eng language. This is international version of mi5 :)
[Xiaomi Mi 5 Guides, News, & Discussion] hitardo:
You are over simplifying the Global / International version of Xiaomi phones.

The Global / International versions have:

- CE Certification (a very complex and time consuming process);

- European charging adapter (official from Xiaomi);

- Support for FDD-LTE, namely B7 @ 2600MHz and B3 @ 1800MHz and, in some cases, even the B20 @ 800MHz (this additional bands cost money);

- English user manual (which is a smart and long waited move from Xiaomi);

- Among others...
[Xiaomi Mi 5 Guides, News, & Discussion] yvessparks:
Please link to where it is confirmed that the device has B20 support. To my knowledge this is not the case with any version of the MI5(s).
[Xiaomi Mi 5 Guides, News, & Discussion] hitardo:
I said "in some cases", like the Redmi 3S.

The Global version of the Redmi 3S has FDD-LTE with support for Band 7, 3 and 20; @ 2600, 1800 and 800MHz.

Mi5's Global version only has Band 7 and 3.

You can see Mi5 here and Redmi 3S here.

Redmi 4A here has the same bands as Redmi 3S.

The Mi Note 2 has (almost) all LTE bands, as you can see here.

Take notice to the blue rectangle on the top of the information section.
[Xiaomi Mi 5 Guides, News, & Discussion] DarknessWarrior:
the non-global (chinese) version of the Mi5 already has band 7 and 3, same goes for Mi5s, the "only" band missing for most EU countries is band 20 (800mhz).

Knowing that 820 and 821 are the same SoC (only high clock speed), and that they share the same modem (X12 LTE), can we use the modem firmware (NON-HLOS.bin) from the global mi note 2 (37 LTE bands) to enable all missing bands? is there any other firmware needed?:confused:

[Xiaomi Mi 5 Guides, News, & Discussion] seb_s:
Did you try the modem firmware (NON-HLOS.bin) from the MI5 Chinese ROM ? That ain't what I meant. I was talking about using the modem firmware (NON-HLOS.bin) from the Mi Note2 Global ROM (http://en.miui.com/download-316.html) which uses the same SoC but it has 37 LTE bands.

That firmaware change and the NV mod maybe do the trick

Oh, I see [MENTION=540955]seb_s[/MENTION], I guess this is my next step then! :)

I'll report on it once I have tried, sometime this weekend (I was not logged in earlier, I'm notnownotnow).
[Xiaomi Mi 5 Guides, News, & Discussion] nicoseb:
Well... don't do that! haha

Not only it did not work, but now it says "no sim" and killed my fingerprint login.

At this point, I'm just gonna search the internet for alternative modems that might work, or not...
[Xiaomi Mi 5 Guides, News, & Discussion] seb_s:
mmm that's sad. I really thought that it will work.

Did you flash it using the fastboot method (fastboot flash modem NON-HLOS.bin), didn't you ? Because if you replaced it (NON-HLOS.bin) in the full rom folder that will not work, you will have a hash/size missmatch.

The readmi note 3 SE is another one with extra LTE bands, but it has a complete diferent modem (X8 LTE). Zuk Z2 and Leeco X829 could work, at least in paper they have the same modem and full bands support.

But I'm convinced to that the Mi Note 2 (Global version) is the key, beacause it has the original chinese bands and all the extras.
[Xiaomi Mi 5 Guides, News, & Discussion] nicoseb:
Yes, definitely fastboot method, much easier anyway haha.

I just tried the MiMix firmware (22 bands and same SoC), as well as Mi5s jsut to see, but same behavior.

I am now rebooting with my original firmware from Mi5... at least SIM is back!

I might try another version of the firmware from MiNote2, and I'll look at those you just mentioned too!

Oh, and another, point I lost half battery in like 2 hours, and phone really hot, because of the no-sim issue...
[Xiaomi Mi 5 Guides, News, & Discussion] seb_s:
Oneplus 3 (A3000) is another good candidate, and even there are flasheable modems in the forum . I just notice that those modems aren't only firmware.... Maybe that's what we miss it :confused:

Hi, these modem flash were based on the phone with the latest 03/30/2017 unofficial MIUI 8.

I have tried the aforementioned ones, plus now OP3 (A3000) suggested, ZukZ2, and latest LeeCo X820... and also another version of the MiNote2 one (8.2.3 global).

All had the same behavior and resulted in "no sim" and dead fingerprint sensor. :(

Feel free to suggest anything else, I could not really find other phones that might work, sigh.

I guess I have to get a new phone...

Forgot to say, I also tried the LG G5 modem (same snapdragon 820 chip and Qualcomm) but same crap...

And the OP3 firmware is the only one that resulted in a soft brick.

Please look into Mi5 schematics. According to it, there's no way to enable B20 or interband CA combos (except CA_1_3/3_1, CA_1_1_3/1_3_1, CA_3_1_3/3_3_1) without deep hardware modification, unfortunately...
[Xiaomi Mi 5 Guides, News, & Discussion] nicoseb:
Well, I wasn't trying to enable band 20 (compare to most) but at least 2-4 or 12 (for T-mobile in the US); and personally, it wasn't for LTE per se, but to enable Wi-Fi calling (because I have a strong sense that both are linked).

Anyhow, thank you very much for this, I tried to find the hardware info a while back but could neither find anything like that nor anyone saying that it was HW related.

Now I know, and I can stop hoping and move on... :)

Anyone with a good suggestion as an alternative to the Mi5? This phone is just unbeatable for quality/cost. Best ideas thus far are ZTE axon 7 mini (heavier not as good) or Sony Xperia XZ (heavier quite expensive)...

[Xiaomi Mi 5 Guides, News, & Discussion] RBSonic:
Thank you very much! Your information really helps me. How did you find it? Where can we find schematics for another phones? Do you know internet sites or forums? Please let me know.

---------- Post added at 01:50 PM ---------- Previous post was at 01:38 PM ----------

Look at MMPA (2. Site). There is a power amplifier sky77646-51 (big chip U200). RF_OUT B20 Port has not wire, it is disconnected. Also there are no filters for this band, and no connection to antenna and RF receive.
[Xiaomi Mi 5 Guides, News, & Discussion] seb_s:
Ok, B20 ain't possible. What about B4?
[Xiaomi Mi 5 Guides, News, & Discussion] RBSonic:
Same problem. RF_OUT B4 is disconnected, no filters, no connection to antenna and receive. Just look at antenna switcher (1. Site, sky13492, chip s100) and power amplifier (2. site, chip U200). There are all ports (bands), which can work. Another bands need deep electronic parts changing.
[Xiaomi Mi 5 Guides, News, & Discussion] chan200606:
This is interesting - the schematics appear to indicate that there are connections at the power amplifier for bands 1, 3, 5, 8 and 2. The part on Sky13492 does show band 7 as well, so maybe the signals for band 7 do not need to go through the amplifier.

Compare this to the list of official supported bands of 1, 3 and 7, and the unofficial enable-able bands of 5 and 8. This may mean that band 2 is another (and the last one) that can possibly be enabled relatively easily?
[Xiaomi Mi 5 Guides, News, & Discussion] RBSonic:
Bands 7, 40 and 41 have an own power amplifier. It must be RF1628 (7. Site, chip U300).

---------- Post added at 06:47 AM ---------- Previous post was at 06:36 AM ----------

Yes, it can be enabled. There is all hardware in phone for this band. We need only software changing.
[Xiaomi Mi 5 Guides, News, & Discussion] RBSonic:
I found some interesting info. According datasheet band 5 can not really work (but i am not sure), because there is no connection to another part of receiver. Bands 1,3,7,39,40,41 have also second connection to wtr3925 (7. Page, chip U300-2, SAW_DRX wire). B5, B8, B2 have no wire to this part of receiver. But B5 must have free place for smd chip for filter.

Indian version mi5 has official B5 in description (according internet shops). I think, there is no problem with B5 in indian version (please control this information, may be i am wrong)

But more interesting is that B5 works with 850 Mhz. We need mi5 indian version. If we add a couple smd to B5 filters, we can change frequency of B5 filter to 800 Mhz (B20). Also we need cut wire from B5 port of power amplifier ( and may be receiver) and solder to B20 port. Don't forget about software changing. We need activate (or write) all software for B20.

Difference between 850 Mhz and 800 Mhz ist not huge. If we get 815 Mhz filter - it is O.K. Signal will be just a bit lower, but it must work.
[Xiaomi Mi 5 Guides, News, & Discussion] chan200606:
There are a few confirmations of b5 working, e.g. see posts #661 and #670.
[Xiaomi Mi 5 Guides, News, & Discussion] RBSonic:
May be we have not the latest version of schematic diagram. But if B5 is complitly work, it is good news.

So i can understand, there are no software for B20 such as for another bands and we need write it? How difficult is this? What do we need for this?
