Yes but you can use the recommended way to remove using terminal from the CM12 thread . I did and all okay and takes less than 5 mins.
[ZTE Z7, Z7 Max, Z7 Mini] Parso:
So finally I've installed 3.12 official and everything looks quite polished BUT it still suffer from the same poor band configuration that existed in the earlier 3.01 beta. Its missing the 900mhz 3G, band B8 which in my country is predominantly used by two of the thee carriers here. Looks like I"m going to have to go in an look at the other band adding thread linked earlier. Very weird that they deleted this band (and maybe more) when they moved from version 2.03 to 3.01, its was also working very well beforehand in earlier releases.
[ZTE Z7, Z7 Max, Z7 Mini] CartmanX88:
Hey, i'm following this thread since a few time now and since you're using the official 3.12 can you tell me is there is still issue using 2 sim like the phone is sometimes sending a sms with one sim instead of the other??

And what about the bands as it's the same in france about the 900mhz one? I never had any issue about this but i never used any rom above 1.82 (currently using 1.42 cos i find it's the one i have the less issues about sms's)
[ZTE Z7, Z7 Max, Z7 Mini] Browne81:
Parso, I have to disagree.

I've got the official 3.12 installed on my Z7 Mini, I've manually installed GAPPS and removed the bloatware but nothing else. I run both a Telstra (850Mhz and 2100Mhz 3G) and an Optus (900Mhz and 2100Mhz 3G) sim in the phone yet I can switch the data between both get full 3G signal on either at my work (I keep 4G disabled on my phone to preserve battery and enhance signal strength on my drive home).

Where I work is rural but we have both a Telstra and Optus tower very close by. I've previously tried to use a handset (Nubia Z5 mini) that only supported 2100Mhz 3G with the Optus sim and found that at my work it would only get 2G signal. At home (about 60Km away and much less rural) it did get 3G signal even though the Optus tower is further away.

Given 900Mhz is better for Australian rural use and the Optus tower at work was only just put in before I got Nubia Z5 mini I'd say it's 900Mhz 3G only while the one near my home is older and I believe still broadcasts on 2100Mhz, hence the above behavior. I'm not sure what issues your having but I don't think they're related to the 3.01/3.12 firmware & modem.
[ZTE Z7, Z7 Max, Z7 Mini] Parso:
Actually I'm glad to see its working for yourself because it now I'm going to have to look a bit deeper into what is going on rather than just giving up altogether.

The thing is its not working on the 2G side of things either but only on the Optus sim, on the Telstra one its fine. Same with 3G fine on Telstra and then with Optus I get some bars with a ? mark next to them. 4G is fine on both. Both sims work well in other phones on all bands so I dunno. So somethings not right ......somewhere.

Whats the most successful procedure for rolling back to earlier versions like say 1.6 or even earlier like 1.4 ?
[ZTE Z7, Z7 Max, Z7 Mini] Browne81:
Parso,

definitely sounds like you've got something else going on there as I've experienced nothing like that with any of the ROMs I've tried with the Z7 Mini. As far as downgrading from Android 5.0/5.1 to 4.4 I've not tried it myself however I expect you would need to start with using the Nubia Updater tool to get it back to stock 1.82 then flash a custom recovery which you'd then use to flash it back to the older KitKat version of your choice. The issue would be finding a 1.82 file that works with the update tool as all the ones I've seen are ZIPs to be flashed via recovery.
[ZTE Z7, Z7 Max, Z7 Mini] nitro2:
Guys i have a problem that I can not solve ... Months ago I mistakenly installed the recovery of the max, by which time the recovery has stopped working, when I reboot into recovery locks that read Nubia, With Flashfy me flash performed correctly but cmq I do not enter into the same recovery, with the command adb reboot bootloader correctly (adb devices me correctly detect the device), arriving in bootloader and when I give the command fastboot flash .... writes by waiting for the device! I do not know which saint to appeal .... Thanks in advance for availability ...
[ZTE Z7, Z7 Max, Z7 Mini] vEEGAZ:
Have you ever found a fix to this? This annoying problem occurs also to the Z9, I've tried different Bluetooth stereos and car radios but the result is always no metadata displayed at all..
[ZTE Z7, Z7 Max, Z7 Mini] Parso:
Yes I've definitely got something going on but at least I now have things working.....sort of, its still possessed but after playing around with things I don't blame the rom

With sim T on its own everything works perfectly in both sim slots, all bands, 2G,3G,4G

With sim O on its own in either sim slot I can only get 4G nothing else.

with both sims in place Sim T works perfectly but Sim O now finally has 2G reception !!!!! still no 3G so at least I can make calls from either provider. It only works with the other sim in place - weird.

There's an option under each Sim setting called "Preferred Network List" and with Sim T I can see the network priorities eg 50501 (utran act) then more. With Sim O (the weird one ) this field is blank completely and there is not even an option to add you PLMN. Perhaps this is not required anyway and its only an optional priority but the fact that its blank with no option to edit or add values has me a thinking.

I'm keen to see what values if any you see here - should be 50502 etc.
[ZTE Z7, Z7 Max, Z7 Mini] Browne81:
vEEGAZ,

I didn't find a solution for the bluetooth metadata issue for the z7 mini however I didn't have to as ZTE fixed it themselves from stock ROM version 1.82 onward.

---------- Post added at 02:31 PM ---------- Previous post was at 02:13 PM ----------

Parso,

I've just checked and my Optus sim comes up with a blank Preferred Network List regardless of if it's set as the data sim or not yet I get full signal on 2G, 3G and 4G. Telstra sim has several entries starting with "50501 (UTRAN ACT)" again regardless of whether it's set as the data sim or not.

If you've eliminated the sims as the cause (I believe you said they both work fine in other phones) and you've tried completely taking the phone back to 100% clean stock (use the nubia update tool as this rewrites EVERYTHING, just remember to remove your sims and microSD first and then test it straight after you've run through the initialization without installing anything or mucking with any of the mobile data settings) then I'd have to say you may have a faulty handset.

The new MIUI 7 has been ported to our Z7 Mini.

http://en.miui.com/download-260.html
[ZTE Z7, Z7 Max, Z7 Mini] Aici:
There is also new official version 3.58 based on android 5.1.1 It has been released today.
[ZTE Z7, Z7 Max, Z7 Mini] buzz-27:
Why is write (MIUI7) after the version of ROM ?
[ZTE Z7, Z7 Max, Z7 Mini] Aici:
Today is the day when 2 roms where releases. Miui 7 and official 3.58. Those two are different.
[ZTE Z7, Z7 Max, Z7 Mini] guidomagaldi:
Does someone know how to install miui 7 from Mokee?
[ZTE Z7, Z7 Max, Z7 Mini] AGelu:
Is there any problem to install from TWRP recovery ? You have to be carefull with radio modem app. Miui changes it to 1.82 version sometimes.

I think you are speaking of MoKee 511 ( 5.x unified partition android )
[ZTE Z7, Z7 Max, Z7 Mini] Browne81:
TWRP should be fine to flash the MIUI 7 ROM however we first need to work out if it's a unified partition ROM (i.e. Lollipop) or a non-unified partition ROM (i.e. KitKat). I haven't played much with radios though so I'm not sure if a 1.82 or earlier radio.img will work with a unified partition ROM.

I did a bit of google searching and I can't find any details about which setup MIUI 7 uses but older MIUI versions (5 & 6) seem to be based off the official 1.82 KitKat ROM which means non-unified partition so to flash one of them you'd need to already be on a KitKat ROM or rollback to one.

The only way to switch between KitKat and Lollipop on the Z7 Mini is via the official Nubia Updater and you need to use a special version of the official ROM (only 1.82 for KitKat, but works for all official Lollipop ROMs) as the normal recovery flashable ZIPs will not work with the Nubia updater. It's easy enough to get the official Lollipop ROMs for the updater either from the Nubia website or links in this thread however I haven't managed to find a 1.82 version that works with the updater.

---------- Post added at 12:00 PM ---------- Previous post was at 11:55 AM ----------

Just to clarify, according to the Nubia forum version 3.58 (based on android 5.1) for the Z7 Mini is a beta ROM not an official release. The latest official ROM is still 3.12 based of Android 5.0

http://bbs.nubia.cn/thread-526898-1-1.html

---------- UPDATE ----------

Update: Found a link with a 1.82 ROM package that will work with the Nubia Updater. I haven't tested it yet however.

3.58 downloads

Thanks to our Russian friends at 4PDA here's some download links for the new Z7 Mini 3.58 beta based on Android 5.1. General feedback (as far as I can tell from Google translated Russian) is a bit mixed with a reasonable amount of people saying it's buggy and they're going back to 3.12.

Stock 3.58 - https://yadi.sk/d/qzzdCC9cii3kg

Source - http://4pda.ru/forum/index.php?showtopic=596441&st=10160#entry42532578

Appears to be a recovery flashable ZIP rather than one to be installed via the Nubia Updater

Partially modified 3.58 - https://yadi.sk/d/acwZYEYOim9WM

Source - http://4pda.ru/forum/index.php?showtopic=596441&st=10200#entry42576995

Again appears to be a recovery flashable ZIP.

Here's the changelog from the Nubia forum:

[upgrade] Android5.1

[New] off charging new visual effects

[New] flashlight new features (status bar quick switch and lock screen long press on the home button to slide Always)

[New increase] application can be moved to SD card function

[optimized] system memory for

SMS interface layout [optimization]

[optimization] text editing, multiple-choice and other controls experience

OTG function [optimized] experience

[optimization] memory leak

firmware optimization including but not limited to, items listed above.
[ZTE Z7, Z7 Max, Z7 Mini] AGelu:
I think that you misunderstood me .

- MIUI can be installed from any unified ROM with TWRP ; I used 2860 version.

- MIUI is still based on 1.82 Nubia ROM. This is the reason I wrote that sometimes it could need to install 3.12 modem app. A link , post #2. I faced this matter - ROM was working but cannot contact GSM networks. Maybe there are a option on TWRP not to wipe ( or install ) modem but it has to be check.

All above consideration are about this summer MIUI versions ( 6 or 7 ones ) . Earlier ones, even based on the same 1.82 Nubia ROM were working only on un-unified partitions.
[ZTE Z7, Z7 Max, Z7 Mini] Browne81:
AGelu,

I did misunderstand. Thanks for clarifying and confirming that MIUI 7 can be installed over a unified partition ROM.
[ZTE Z7, Z7 Max, Z7 Mini] supercowz:
im in same boat as you with my free mobile im stuck with 3Gb data, and now today free update from 20gb to 50GB !! but still stuck on 3Gb because of that dam wrong ZTE imei not officially LTE ...

did you find a way ? on my side ... cant change imei .. write protected ...

edit : i found the way to at last change wrong IMEI...

1)with nubia updater v2.0.0 made a NV backup by flashing orignial nubia fw 3.01 !! located in c:\nubia Backup

2) edit your nv c:\nubia Backup zip with desired IMEI and NEW MEID ! (unzip nv.qcn then edit it and put it back inside zip) you made with nubia updater v2.0.0

3) save and delete fsg modemst1 and modemst2 partition

modemst1 -> /dev/block/mmcblk0p10

modemst2 -> /dev/block/mmcblk0p11

fsg -> /dev/block/mmcblk0p20

save with adb and keep them is safe place in case of .... :

dd if=/dev/block/mmcblk0p10 of=/mnt/sdcard/modemst1.bin

dd if=/dev/block/mmcblk0p11 of=/mnt/sdcard/modemst2.bin

dd if=/dev/block/mmcblk0p21 of=/mnt/sdcard/fsg.bin

now we will empty them with dumy file filled with 0 but same size (1*572*864 octets), so secure write will be gone

here is my dumy file : https://dl.dropboxusercontent.com/u/28377348/dumy.bin

put dumy.bin to internal sdcard

with adb :

dd if=/mnt/sdcard/dumy.bin of=/dev/block/mmcblk0p10

dd if=/mnt/sdcard/dumy.bin of=/dev/block/mmcblk0p11

dd if=/mnt/sdcard/dumy.bin of=/dev/block/mmcblk0p21

then reboot ...

now if you check Imei ... all will be empty

now flash back your modified nv c:\nubia Backup with nubia updater

launch nubia updater then clic on red circle nubia logo on top left to launch nubia restorer v1.0.0

then flash back your modified NV backup with desired IMEI/MEID

and to fix the imei permantently flash again orignial fw 3.01 with Nubia Updater, it will create NV backup with your new iMei/MeiD, then Fw 3.01 and then reflash them back permanetly... finish !!

now you can install your custom FW ... cucoco92 or other ...

now need to check if it work with free mobile 20GB

Hi,

After I flashed my device (ZTE Nubia Z7 mini Dual Sim) into this version rom (NX507J_CNCommon_V3.01). I tried to return to my old version (NX507J_CNCommon_V1.72) by using this software (nubia NX507J Updater V2.1.0). The operation was failed, and the software system stuck in v3.01. So I need your help.

[ZTE Z7, Z7 Max, Z7 Mini] supercowz:
important if you change imei you have to change meid too, if you use your old original meid with new Imei, then only data will work but no call

i guess free.fr mobile will lock since meid was used to your old imei, so generate new meid too

when is done

flash again orignial fw 3.01 with nubia updater then it will fix your NV modif ....

I think its an issue with Mokee, I lost my vibration completely aswell, its pretty quiet for quite some time now and I have started to think it is a hardware issue, but there are more peoples reporting of a completely broken vibration wich makes me wonder of ins't just a software fault.

Flashing back to stock, with the Nubia tool might help, but haven't tried that yet.

Flashing CM or something simular in recovery doesn't fix it.
[ZTE Z7, Z7 Max, Z7 Mini] Exedion:
I can flash the lasted stock rom from a custom? Where i can find the stock rom?
[ZTE Z7, Z7 Max, Z7 Mini] Browne81:
I'm also on Light X 3.65 which I believe (from reading poorly translated Russian) is simply the stock 3.65 with the bloatware and Chinese only apps removed but I don't believe it has root or GAPPS. I got root via TWRP notifying me post flashing that it was missing. I then ran through the Nubia setup, rebooted into TWRP and flashed the Slim GAPPS for 5.1. All seems to be working well, no bugs or issues so far and battery life seems to be fair to good, about the same as 3.12.

I flashed direct to 3.65 from the latest Mookie 5.1 using TWRP and haven't had any issues. However from reading this forum and 4PDA is seems like you have to have the 3.12 radio for 3.65 (or 3.63 or 3.58) to work properly and before I put Mookie on I first restored the handset to stock 3.12 via the Nubia update tool.

So basically what I'm saying is that you can flash 3.65 from a custom ROM as long as you have the 3.12 radio. If you're at all unsure use the Nubia update tool to restore the phone to stock 3.12 then replace the stock recovery with TWRP and you should be good to go.

There's a link to the Light X 3.65 a few posts up (#1159 by AGelu) and it doesn't seem to have anything extra added, just stock with the bloatware already removed for you.

Thanks in advance!

[ZTE Z7, Z7 Max, Z7 Mini] AGelu:
There are an option in Xposed Module to remove it. See on Adroidiani a topic about it or search for Solar Warez ones here on Xda or 4Pda.ru
[ZTE Z7, Z7 Max, Z7 Mini] Browne81:
TWRP 2.8.6.0 from Cuoco92. Comes with some nice little scripts to get it installed easily.

Also what ROM do you currently have installed?

I'll second AGelu, the XNubiaUI module for exposed is a must for anybody wanting to run a stock Nubia ROM. It has many more useful tweaks on top of the "remove the left homescreen"

If you have trouble getting exposed to work however you could simply just use a third party launcher. I generally use Action Launcher 3 (paid) and find it 100% stable with good performance plus tonnes of customization. Some others you may wish to check out are Nova Launcher (both free and paid), Google Now Launcher (free but has it's own annoying left homescreen), Yahoo Aviate Launcher (free but lots of intergrated Yahoo) or Smart Launcher 3 (free and paid).

So I flashed the CM11 that I downloaded from the link that yiphoming provided and didn't have any issues with flashing. First boot up was wicked slow, a bit of bloat - that was a pain.

A couple of observations:

- It didn't seem as customizable as mokee.

- I used it for about 24 hours and had signal issues for phone and data seemed very slow.

- Bloat was a pain to take off and in the process I seemed to have lost (or deleted accidentally in the process) the ability to view photo thumbnails.

I'm curious to see what else Seyron has to post. For now I'm back to the buggy version of mokee; if nothing else, I'm familiar with it.
[ZTE Z7, Z7 Max, Z7 Mini] Seyron:

Added everything new I found including many "new" (as some are released months ago but still are new because I just found them recently) ROMs and many informations in the first thread such as gapps, recoverys, Service Codes, "How to change the MAC" etc. I also found there two zips for changing the touch keys (interchange Menu and Back) like it's possible on stock ROM, which are intended to work with a new Mokee from 4PDA released just yesterday (1st November) - would be interesting if they also work for other custom ROMs!
