Seem to may add band 20 4G on Quallcomm socs, for example the OPO.

But a custom kernel is required, as the code that Quallcomm added that blocks it must not be in there.

ok i have managed to back my nv and efs with the help of nubia forum
[ZTE Z7, Z7 Max, Z7 Mini] pedrud:
No, you cannot. See this thread on the Nubia forum. CM12 and Mokee are still technically considered 4.4 because they do not use the unified storage. You will most likely brick the phone if you attempt to flash it. You have to first use the Nubia updater to go back to at least 1.82, then you can use CM12 or Mokee.

Hi guys just an off topic sorry, how do you remove the sim from the phone? Do i just need to pull it out or you can open something? Thanks
[ZTE Z7, Z7 Max, Z7 Mini] Leo_83:
Remove the back cover and slide the card out.
[ZTE Z7, Z7 Max, Z7 Mini] pedrud:
Can anyone help me? I was trying to flash the new CM12.1 using TWRP and in the middle of it the phone went black. Now I can't turn it back on, can't do anything. Ideas anyone? This sucks. Fortunately, I just did a backup of everything, but now the phone won't even power up. I'd appreciate any suggestions. Yes, I had already upgraded to the official nubia beta.

Edit: The phone still won't turn on, whether it's plugged in or not. However, when I plug it into the computer I can see 5 different partitions of various odd sizes with different aspects of the phone software visible.

Edit 2: So I did a hard reset and was able to get back to TWRP. Next I tried wipe data, cache, dalvik and it did the usual trying to format partitions and it kept failing, saying it couldn't access data. I tried flashing CM12.1 and it gave me the same error, although it said it installed successfully. I also flashed gapps. Now I'm waiting for it to boot up.
[ZTE Z7, Z7 Max, Z7 Mini] chalimoja:
Android 5.1 CM12.1 So Far

Well just tried out CM12.1 for one day. The ROM so far is butter smooth. Navigation through the whole UI is just smooth probably the best ROM in that respect. No bugs to report of expect one major one which is that the Contacts app is just totally messed. First you cant make calls from the phone book. Once you select a number to dial the phone reboots itself you also cannot use SSD codes on the dialer if you have 2 sim cards. The phone reboots itself. Most guys with a single sim card will probably not notice these errors.

Other than that its a pretty solid ROM and a whole lot better than the Nubia 5.0 Lollipop app which has numerous bugs and is super laggy.
[ZTE Z7, Z7 Max, Z7 Mini] pedrud:
I would completely agree with you. Although, i only use one SIM, so I haven't noticed any of those issues. I've been using it for almost 24 hours and have not had any spontaneous restarts as of yet. Other than that, seems like a stable and very good ROM. Much, much better than the Nubia beta.
[ZTE Z7, Z7 Max, Z7 Mini] MirosPikos:
And what about Nubia Camera in Cm12.1?
[ZTE Z7, Z7 Max, Z7 Mini] voetbalremco:
Thanks for your experiences,

So its quite good? ;)

How about battery, does it perform a bit like the old roms or eats much??
[ZTE Z7, Z7 Max, Z7 Mini] pedrud:
Yes, so far I do think it is quite good. For the first 7 months or so that I had the phone I only used Mokee and battery life was very bad. I've also tried many of the other 4.4 ROM's available (CM11, MIUI, IUNU, FIUI, LEWA, Baidu, YUNOS) before I changed to the official Nubia Lollipop beta. Of all of them, I liked Mokee, CM11, and FIUI the best. I really liked some aspects of YUNOS, but there were too many issues to make it worthwhile. So far battery life has been the best with CM and FIUI. So far I still think the battery life is good with CM12.1. I mostly use the phone for work (email, phone, SMS, web), but obviously personal too (similar to work, also RSS reader, sometimes movies, and a couple of small games) and so far CM12.1 seems to have very good battery life, similar to CM11 or FIUI. Like I said before, I've only been using it for 24 hours, but so far I'm happy.

---------- Post added at 05:53 PM ---------- Previous post was at 05:51 PM ----------

So far no, it does not work. I've tried installing it and the app will not open. If you read the Chinese forums (and one person mentioned it here on XDA), it is not a stand alone app. This is really too bad, because that was the one thing that I really liked about the Nubia beta Lollipop.
[ZTE Z7, Z7 Max, Z7 Mini] jamieboy2014:
Crashed

I was loving cm12.1 until it crashed when I was playing FIFA 2015. The screen went totally blue and afterwards would not boot past the cm logo. Had to wipe all data in recovery to get the phone to boot again
[ZTE Z7, Z7 Max, Z7 Mini] pedrud:
Next time try wiping only the cache and/or dalvik cache in the recovery. It may be an easier (and less painful) solution. I had the exact same issue with my calendar app in CM11. Somehow, some of the data (most often in the cached data) gets corrupted and unusable. This can cause the app to crash or be unusable and may even force a reboot. Hasn't happened to me yet with CM12.1.
[ZTE Z7, Z7 Max, Z7 Mini] alain57:
you forgot one important bug : GPS is not working ^^ (if you try google maps make sure that the gps settings are setup with device only, otherwise maps will use wifi or network to do an approximative location... )

for the other bugs, i can't confirm as I have just one sim card
[ZTE Z7, Z7 Max, Z7 Mini] pedrud:
So I did a little reading and found a discussion on TDbeta about this topic. Apparently (according to someone on the thread), if you download the official apk file from the Nubia website you need to change the permissions for third party to read/write. After that, you put it in /system/app on your phone and reboot the phone and it should work. I'm going to try it, but haven't had time as of yet. I hope it works; the new camera on the Nubia beta lollipop was great. It was the only thing I liked about it.

Edit: So I attempted to do this without any success. Here was my process.

- Download app from Nubia website.

- Move apk file from download to /system/app

- Enable root acces for file manager

- Change permissions of Nubia Camera to rw|rw|rw

- Reboot phone

- Open app - The app will open and you can slide through the first three screens showing you some of the features. However, when you click the button "Welcome To Nubia Camera" you get a pop-up notification "Unfortunately, nubia Camera has stopped."
[ZTE Z7, Z7 Max, Z7 Mini] simrim1:
Did you try moving camera lib files to appropriate location? Normally it should be moved to /system/lib. Lib files can be found in apk file in lib folder if you open it with zip archiver. I've made a number of apps run by moving lib files. Let us know if there is any success. Don't forget to change permissions on lib files as well.
[ZTE Z7, Z7 Max, Z7 Mini] pedrud:
Great idea; hadn't thought of that yet. Tried it, didn't work. :confused:
[ZTE Z7, Z7 Max, Z7 Mini] Exedion:
You use english locale? The nubia camera crash in others languages
[ZTE Z7, Z7 Max, Z7 Mini] pedrud:
Yes, I use English. Unfortunately, nubia camera will not work on CM12.1

[ZTE Z7, Z7 Max, Z7 Mini] sepacek:
Yes,if u want LTE bands 1,3,7,20 type in 524357 in both ID´s 06828 and 06829. I just did it however band 20 wont work :(
[ZTE Z7, Z7 Max, Z7 Mini] alain57:
I did the modification on cucuo92 rom

i went back to CM12.1 and noticed that TWRP restaure an NV partition... So i first told TWRP to NOT restaure this partition => phone did not boot

So i had no choice and restaured this partition after all

well I went to a town where there is ONLY LTE 800Mhz, and like I expected did not work :/

So I guess that the NV partition backup in TWRP contains the NV changes :/

Nevertheless, i'll retry this with Cucuo92 rom to be sure that this mod is working on my phone

if it is, i will create a NV backup and try to compare it with the backup I already have (cucuo rom without changes)

and then I'll try to do the exact same difference on the CM12.1 NV backup... maybe this could work

by the way, I guess it would be a lot better to start a new thread for this modification, as this has nothing to do with ROM collection ;)

ps: it may be possible that the number I put in was wrong ... I used the NV calculator tool in the marked and the thread on XDA says that it may deliver wrong numbers :/

---------- Post added at 01:29 PM ---------- Previous post was at 01:26 PM ----------

you need to use another tool to do the LTE mod, the window you are showing is the one for UMTS (3G) modification

this window need to stay open, but the LTE mod are done in one other tool
[ZTE Z7, Z7 Max, Z7 Mini] pedrud:
So I was reading a little deeper in the thread and a few interesting things came out to me.

CM is known (as of last September) to have added a commit to their code to prevent these changes (my guess is because of their rapid growth and wanting to play with the big manufacturers), so CM12 or CM12.1 may not successfully do this.

It seems that this only works with custom ROM's/kernels that have been compiled from source (meaning Cuoco's ROM is built off of Nubia and they likely are preventing it in the kernel)

It seems the phone has the correct modem to make this happen, but we may also need a custom radio compiled to enable these bands to work - although it seems some people in the other thread have had issues with this. Some say it works and others not so much.

There's more but I don't have time at the moment. I'll try and add more later.

Edit: I'm also very interested in this topic and getting these changes so I started a new thread; Nubia Z7 mini (NX507J): Adding LTE bands.
[ZTE Z7, Z7 Max, Z7 Mini] El Philou:
Read carefully again the guide ;) This is only for UMTS ( 3G ) , for LTE is point 23 :)

So if you don't want add 3G band, skip points 12-22, go directly to point 23

See the 3em post to calculate the magic number for 6828 and 6829 ( http://xdaforums.com/showpost.php?p=55635592&postcount=3)

Just to complicate things though, QXDM lops off the zero placeholder just to be different.

[ZTE Z7, Z7 Max, Z7 Mini] alain57:
ok i just tried some conversion

i wished to have following LTE bands ON : 3 + 7 + 20 (all other can be off as they don't interest me)

so i need to write this binary value :

starting with the bigger number 20 has 1

then rows 19 to 8 has 0,

then row 7 has 1

then 6 to 4 has 0

then row 3 has 1

then rwo 2 to 0 has 0

100000000000010001000

I convert this to hex (there are online website)

that would be : 10.00.88

I remove the leading 0 (there is none, so nothing to remove)

and i swap the hex value

88.00.10

finaly i convert back to decimal :

8912912

am I correct ?
[ZTE Z7, Z7 Max, Z7 Mini] El Philou:

with QXDM, Start at 1

[ZTE Z7, Z7 Max, Z7 Mini] Leo_83:
Well it isn't official yet is it? From what I understand it's just a beta version of official. If it is a beta t you'll probably need to flash it via recovery.
[ZTE Z7, Z7 Max, Z7 Mini] MirosPikos:
Bull****, he have to use their flash utility. NOT RECOVERY.
[ZTE Z7, Z7 Max, Z7 Mini] pedrud:
That is correct, you have to use the Nubia PC tool because of the changes it makes for the unified memory. You cannot easily flash back and forth between the Nubia beta and other ROMs, unless it was one developed with unified storage, of which there are 2 or 3 at the moment. You must use the Nubia PC tool and follow the directions specifically. Just read the Chinese forums, if you don't do it just like the directions state, you may brick the phone. A number of us here on XDA have already talked about it (including the process) and done it, just read back a few pages.

So far, very few people have actually liked the beta ROM. The only thing that was great was the camera, but it seems tied to the ROM itself (see other discussions here too). Right now (as far as I know) Cuoco has their's formatted for unified storage, there is a Chinese version of CM12 and CM12.1 also. Just so you know, the CM does not currently have functioning GPS and some people have mentioned problems with BT too.

SMS issue with 2 SIM

Hey everyone, i'm here to ask for you herlp if anyone can because i've looked for a few time on the internet and i haven't found anything like the problem i have.

Let me explain: With every rom i tried from 1.60 included to 1.82, if i send a SMS with, let say SIM 1, and it doesn't have network the SMS is automatically send via SIM 2... Not to say it's pretty annoying and can also lead to some troubles :/ )

I've already tried several rom out there (1.60 untouched, 1.62 untouched, 1.62 4G Fix, 1.72 untouched, 1.72 Deodex, 1.76 4G, 1.80 untouched, 1.80 4G, 1.82 untouched and 1.82 Gapps)

Thus, the only one i'm good with is the 1.42 (or 9.42) but it miss some features i would like to have and some stability improvement that i noticed in the other roms.

If any of you can provide me some help knowing i've already tried a lot i would be very pleased. Maybe i've missed an option, even if i'm almost sure i don't (i've read on that thread that some were talking about 4G autoswitching but that's not the problem i have, therefore maybe there's a trick somewhere to prevent that SIM autoswitching for sending SMS :/

Edit: I even had the case of receiving the same SMS on both SIM at the same time as the sender doesn't even have my 2nd number... I think that could be a very useful thing to know but i have no idea why that occurs :/

Thanks for reading and have a good day :)

[ZTE Z7, Z7 Max, Z7 Mini] pedrud:
If you read on the Chinese forums, this is a

very

common problem right now. At the moment, there does not seem to be a fix available (at least from what I understand); also from what I understand; many people believe that it will be fixed by Nubia in the next official update - though no one knows for sure. While I certainly don't know myself, there are also rumors (and only rumors, no confirmation) on several forums that after this update for the z7 mini, Nubia may abandon it like they did for the z5 mini once the z7 series came for sale. All this is because the z9 will be available soon.
[ZTE Z7, Z7 Max, Z7 Mini] CartmanX88:
That's quite strange as i never had this issue as long as i had the 9.42 rom but i wanted to upgrade to 1.82 and then the problem occurs. The only way to avoid it is to get back to 1.42!! That's a non-sense that every rom out since the 1.42 have this issue oO

And yet i don't usually go on the chinese forums sorry :/ i didn't even know it was a common issue :/

I've never had this issue on any of my other dualsim phone i'm quite disappointed about this :/

Let's just wait and see then :(

Edit: For what i'm aware of, Z9 is ever available and i don't even understand the point of this phone oO I found it less attractive and even powerful than Z7 (both mini i mean) except features like camera and some stuff we don't really notice ><
