I have problem with last CM12.1-very often crashed dialer :( Almost every time after call and sometime in time of call, say Unfortunately Dialer has stopped and call ended. It's very annoying. Someone else have this problem? I think may be problem in new android 5.1.1 or if nobody has same problem i will find what software cause it, because i try to reflash with wipe but problem still here(
[Device Reviews and Information] mn31pro:
im using cm 12.1 build 20150910 it is perfect and i havent your problems.
[Device Reviews and Information] alexeei:
Do you flash updated GPU driver? It's very strange, i again flash firmware(with all wipes), gpu driver and gapps, nothing more and after first call has this dialer crash :confused:
[Device Reviews and Information] mn31pro:
no im just flash rom & gapps.

updated gpu driver is very buggy.

with build 104 i cant run any games and test antutu benchmark but original gpu driver of cm12.1 is very stable and smooth.

Problem with waze

Hi, is anybody of you, folks, using waze? On all CM builds till now I have been faceing issues with it. It is working normally till I start navigation. Then my phone always softreboot.
[Device Reviews and Information] ragnarokgr:
Hi guys, i just ordered this great phone and i have some questions i want to ask you.

I have a lot of questions so please bare with me. I'll number them to make it easier to answer them.

1)So far the latest CM build is cm12.1 B06 right?

2)To install it i have to first install the chinese CWM then merge partition (if i want the merged rom) then install the rom from external sd, then clear caches and reboot.Did i get that right?

3) What is the difference between merged and not merged? i read it combines /data and /sdcard0. Does that mean that when we merge we get all the internal storage as /data and we have like 16gb for installing apps? If that is so then we have no space for music and photos? Do i need an external sd in this case? If someone can tell me the amount of space we get it would be nice.

4)If i install cm12.1 B06 which gapps can i use with that rom and where can i download them?

5)Can i install the gapps from CWM or does it only work from TWRP?

6)If i have the chinese CWM there is no reason to download TWRP, or do people use TWRP because they can install english language?

7)TWRP only works with merged roms?
[Device Reviews and Information] 5KKKKK:
1)Yes, released on 10/9. It should be B07, because I forgot there was another B06 released on 28/8 and named it wrong.

2)Yes, clear caches should be two wipe

3)It merged /data and sdcard0, then about 12G total available for installing apps and media

4)I'm using this one, works fine and it's always up-to-date. http://xdaforums.com/android/software/app-minimal-gapps-gapps-lp-20150107-1-t2997368

5)Chinese cwm for merge partition can NOT flash anything except rom file, including gapps. twrp for merge partition rom can

6) Because they need to flash gapps or other things

7)TWRP for merged partition rom is yes. Both Chinese cwm and twrp have two version, one for merge partition while the other not. Depends on which kind of rom you're using and want to install. Chinese cwm for merge partition can install any rom
[Device Reviews and Information] ragnarokgr:
Thanks for the help. Now i have a final question. If i install a NOT merged partition rom then how can i install TWRP if it is only for merged partitition rom? or can i install gapps from CWM if i have the not merged partition rom?
[Device Reviews and Information] 5KKKKK:
Then you can use TWRP or cwm that not for merge partition version. As I said before, Chinese cwm for merge can not install gapps.

And there is another Bilingual cwm(Chinese and English) for not merge rom. all recovery can found from my previous post, I post them in this thread long long ago.

Hello.I just flashed official B16 because i thought it was a 4.4 rom.After that i got back to cm 11 but the screen only works in B16.The links from post 1676 are not working.Any solution?Thanks.
[Device Reviews and Information] ragnarokgr:
Well i got the phone in my hands and i installed the CWM and the NOT merge ROM just fine along with the gapps. I have an issue though and i don't know if it is just my phone or a general issue. Whenever the phone gets hot, like above 38°C, i see that the maximum CPU clock falls from around 2.3GHz to 1.7GHz and even when i go to the performance tab and set it back to 2.3GHz it won't go unless the temperature cools down.

It's a minor issue i don't really care about but i want to know if it's a thing in android or the phone decides to underclock itself to cool down.

But hopping for you its not a hardware problem..
[Device Reviews and Information] Xrunner87:
Alright, do the following step to make sure it is not a hardware issue. Press the 'pick up(I don't know what the botton called)' botton on your headphone when you are listening to music. If the sounds goes right, your phone is OK, just the problem with your headphone. If not, (Due to my English level, I don't quite understand your meaning) you may have to send it to the service to see if it is broken. Rember to flash a official ROM and the official recovery before you give your phone to thr service.

My experience setting it up so far

I received my S291 for one week already. I am still setting it up, finding a good rom, deleting apps and so on. I have not started using it day to day. I just like to share my experience so far.

I received the phone with rom B08. It was not rooted properly and without Google Play. So I follow the instructions in the other thread on rooting, and got it rooted and 3rd party Chinese recovery.

I then downloaded (I believe it's the official rom, and the latest - correct me if I'm wrong) from myzte.cn the MiFUI 2.3.4 B10 rom. After installing it, root was gone, Chinese recovery was gone. So I had to re do these two.

The battery life was quite good. But out of 970+ MB in system rom, only 200+ was left available.

I then downloaded another modded rom by room制作. His is also, I believe, based on the official B10, but added CM launcher. Personally I prefer this as it looks better, and I can change the battery icons on the status bar. But I think the battery consumption is higher.

I also found a list of removal able apps from myzte.cn (I can read Chinese) but not many of the listed apps are actually listed in Titanium Backup, if you get what I mean… Anyway I have deleted several Chinese apps, such as Baidu, the browser and the file manager.

I can make the resources available if I am allowed to, of course, I did not make them. So credits go to the original authors.

I will try to post some pictures later.
[Device Reviews and Information] ah zek:
Here are the photos. You can see that the battery slided down over night...

Questions: Does anyone know how to do screenshots? I have not found it yet. Also, is there an extended power menu?
[Device Reviews and Information] chetbiz:
screenshots : power+volume down
[Device Reviews and Information] 5KKKKK:
the latest official rom is B10 with MF2.3.5,came out last night.it's here： http://www.myzte.cn/thread-178278-1-1.html

there are two methods to do screenshots:

1.press the volume down key and power key at the same time,about 1～2s

2.go to setting, enable the first choice in the first pictures below.and you can click the first choice and then go into the second picture,enable the last choice. the third picture tells how to do screenshots

May be there isn't an extended power menu in official rom

BTW,here is another mobile forum for s291,there is an English recovery CWM6.0.4.9 and many other roms: http://bbs.anzhi.com/forum-1339-1.html

for example,here is a rom with extended power menu： http://bbs.anzhi.com/thread-9077796-1-1.html

mine is official rom B10 with MF2.3.3

sorry for my bad English and hope you can understand what I say:)
[Device Reviews and Information] ah zek:
Thanks to chetbiz and 5KKKK :)

Hi guys,

have anybody tried this rom - http://www.myzte.cn/thread-216216-1-1.html,?, It has 2 files but I can´t download them:(, what do you say about it 5kkkkk? Does it worth to try it?

thx :good:
[Device Reviews and Information] alarik1:
What main this about #1676? I dont understand.

Give me the url to CM 12.1 B07 and MF 3.2.6 please, i will try.

I think this: The stock rom B16 change the firmware of touchscreen to one new revision, so the previus custom rom based in previus stock revision (b14, b12, etc) wont work the touchscreen. I need one custom rom based in B16 stock revision where i can install google apps (there are in zte forums but everything are written in chinese.. imposible for me), or the google apps for B16 and this will be solved. Or anything which clean the firmware touchscreen of stock rom B16.

Try install b16 stock rom, after, try install other custom rom not based in B16... noone wont work. I think this is the reason, B16 change the firmware of touchscreen forever.
[Device Reviews and Information] 5KKKKK:
It meant if you want to flash miui7 or official kitkat, you need to flash one of those files after flashing rom file, MIUI7 is here: http://www.miui.com/download-245.html , I recommend the third one

Of course B16 have upgraded screen driver, and it can't downgrade, so you need that file. But cm12.1 B07(#1777) and MF3.2.6(#1772) support new driver, so they don't need them, you can just flash the rom.

I think you're new here, so you'd better take some time to read this thread first, actually all things you need have been posted here

Well, I don't think it worth, it's too old and stop update. And I won't flash that guy's rom, like many Chinese users did

After root with 中兴天机S2一键ROOT_Recovery.exe , i got chinese recovery and flash miui v7 from sd card, before that i had official 4.3 b16 rom.

The problem is my touch screen does not work att all now.

SOLVED:

I flash back to 4.3, ZTE_Grand_S_II_LTEV1.0.0.B16 and phone boots normaly and touch is working. It got to be this rom, other b16 didn,t help.

Is this the answer for built in google play rom (firmware) with working screen in #1797 : cm12.1 B07(#1777) and MF3.2.6(#1772) support new driver, so they don't need them, you can just flash the rom.

So can i flash cm12.1 B07(#1777) or MF3.2.6 from zte recovery or i must put chinese recovery first with 中兴天机S2一键ROOT_Recovery.exe ?

I hope you understand me, i want working rom with google play in it and without touch screen problem and how to flash it from my sd card.

if i need chinese cwm to install cm12.1 , can some one translate it to english, i know i saw it somewhere in forum but i cant find it now.
[Device Reviews and Information] alarik1:
I had exactly the same problem. When you install the firmware B16, this install a new firmware for the touchscreen (and you can not come back to B15 firmware), for this reason previus roms based on B15, b14, b13, etc firmwares dont work.

Read the post in this thread, they are written in english, and you can solved it.

you dont need chinnese recovery. Go to B16 firmware (where your touchscreen works), root and flash the cwm recovery following this (and read my questions and answers about flash recovery, etc): http://xdaforums.com/android/general/zte-grand-s-ii-root-install-custom-t3098917#post63205045.

You can install cm 12.1 b07 (with his special guide of this thread), install miui 7 (using a patch for the new firmware touchscreen of b16) or install any rom for S291 based on kitkat (using a patch for the touchscreen too). These patchs are flashed after to flash the new rom, before of restart recovery (so togheter). The patchs are in the message number #1676.

Relax, all the answers for this problem are in this thread, i had exactly the same problem. Read my messages and 5kkkkk's messages for me.
