Bug: wifi goes to 0 Mbps, wpa_suplicant ERRORs

@Bruno

I've experienced problems with wifi connection in your JB v1.0.

First, the wifi indicator at the status bar gets stuck, i. e. it does not upgrade.

Second, after that, the signal quality drops and the speed goes to 0 Mbps (or before that 1 Mbps for a short time).

The wifi connection is lost, however the system says it's active.

This behaviour can be reproduced by actively using wifi for a prolonged period (~15-20 minutes).

The wifi connection can be re-established only by disconnecting and reconnecting manually.

And after 10-20 minutes active wifi usage, the above repeats.

I suppose this problem is caused by wpa_supplicant. Its service produces

many errors

(E) in logcat.

I have attached two screenshots right after the problem appeared: on the first, wpa_supplicant displays errors for every available access point.

Please, Bruno, don't ignore this, because this bug can affect many users.

JB 1.0 issue

Hi!

The JB ROM is almost perfect - many times daily, it's dropping SD Card with an error message (the phone is not used, in sleep mode), then it automatically remounts it, but ringtone is dropped some times... "SD Card unexpectedly removed"
[ZTE Grand X V970] jonzalvo:
+1

happens to me as well.
[ZTE Grand X V970] bgcngm:
Anyone else confirms these WiFi connection issues? I still haven't noticed that problem.
[ZTE Grand X V970] darkguy2008:
Well, in my case, if I use WiFi the phone seems to:

1. Long-vibrate when receiving a notification and flashing red led.

2. Hangs for about 2-4 seconds when typing, or receiving any kind of notification.

It doesn't happen if I switch WiFi off. I've also tried reinstalling the ROM and the same problem arises.

I assume it must be something with the WiFi modules or binaries, judging from the new .ko files related to the MT chipset. Maybe they're different in the JB version? I doubt so but...
[ZTE Grand X V970] jonzalvo:
not only freezes my phone, it also affects my whole of my home wifi network.

* Until you turn off and turn on again the wifi phone, any device in my house has not wifi

Re: [ROM][16-02-2013] ZTE V970 (MT6577) custom ROMs (ICS / JB)

I don't have the problem
[ZTE Grand X V970] anglergab:
The wifi problem exists, see the logs. But it could happen, that some circumstances must occur at a time, in order to turn it up for someone.

Maybe we could try to go back to Ice Cream Sandwich wifi drivers (.ko, etc) and related services (e. g. wpa_supplicant), which are supposed to function correctly. Do you think, the ICS drivers and services would function correctly under JB? I don't think that kernel related drivers would, because the kernel has changed.

But if wpa_supplicant causes the problem itself, could the ICS version be compatible with a JB system?

For me Wifi work good, but proximity sensor lag

Re: [ROM][16-02-2013] ZTE V970 (MT6577) custom ROMs (ICS / JB)

I'm not saying the logs are fake, don't take me wrong. It just doesn't happens to me and I can't seem to be able to replicate it. You can try replacing wpa_suplicant just to see if it solves your problem.
[ZTE Grand X V970] Jebusura:
I use WiFi a lot and it's worked perfectly, I'd even say it has a very small boost compared to previous versions but I can't say for sure. But overall not a singe issue with WiFi.

I've also played around with it a lot this last week and it seems like a very solid base to start adding the modifications you had for previous releases (battery percentage indicator, that sort of thing).

Any bugs I did come across I managed to trace them back to a mistake on my part and not the actual ROM
[ZTE Grand X V970] sianhulo:
Re: [ROM][16-02-2013] ZTE V970 (MT6577) custom ROMs (ICS / JB)

Same here, I use wifi a lot and haven't had a single problem with it. The only bug I have is with my home screen, I lost the f configuration and my widgets every time I reboot (so it boots on stock launcher instead of nova) and have to touch the widgets to reactivate them
[ZTE Grand X V970] mmichal2:
For sure not, but I don't see any errors there either.

It could be problem on the access point side, or any other wifi device at home. JB has many fixes (as we have new kernel) to wifi drivers.

As few persons say there is no problem with wifi, anglergab - do you have your access point up to date with last firmware? And please specify test case.

For me Bruno should release it like it is now (wifi part) and we all can test it more.

@anglergab it looks like problem is your device or AP.

[ZTE Grand X V970] Siendor:
Anybody else experiencing the same problem? It's pretty annoying... I tried to reinstall it, but that's the same.
[ZTE Grand X V970] anglergab:
I've managed to reproduce the problem (by watching Youtube videos for 15-20 minutes) with another wifi channel. So interference cannot cause the issue.

My access point has got latest firmware, but it's quite old and unsupported.

I suppose the problem could be reproduced by downloading large files too.

Install Custom Reovery

Hello everyone,

I bought this phone a few days ago and i should receive it in a week or so. I have read all the initial information about installing this rom and recovery. Althought i have a doubt about installing recovery.

I understand i have to install usb drivers and latest sp flash tool. I initiate sp flash tool, load the scatter file thats on the paste of recovery (only scatter file, nothing elese), select ONLY recovery in sp flash tool and un check all others options and hit "download" , then i connect the phone to computer shut down. And the sp flash tool should automaticly begining to flash the recovery... Is this all correct?

After this installing the rom is the same as in others phones so i dont think installing the rom will be a problem. I just need to confirm with you all the recovery instalation part. Is the steps i described are all correct.

Thanks in advance to you all
[ZTE Grand X V970] bgcngm:
That's correct. Just like as described on my tutorial. ;)
[ZTE Grand X V970] mmichal2:
Most of sellers send it with recovery installed already, there was Bruno 3.0 ROM when I got mine.
[ZTE Grand X V970] lurkerPL:
I've had chinese recovery on my V970, useless...
[ZTE Grand X V970] bgcngm:
I hadn't noticed that feature until now. However, I have also added battery icons with percentage, so it's up to users choice.

Yesterday, after you reported those issues I have tried watching YouTube videos for half an hour and simply couldn't reproduce the problem. I guess the problem is really on your setup. Have you checked if is there any 3rd party app that may be causing those unexpected issues?
[ZTE Grand X V970] anglergab:
I use Wifi High Performance Widget to lower latency and to avoid wifi "micro sleeps". With your ICS v2.3 rom (and this app activated, too), I didn't experience any wifi connection issues. Also, the problem didn't appear at other access points with your JB v1.0, but it could happen, I didn't use wifi long enough at that other router.

While further testing today, I have experienced sudden (warm) reboots:

- once while downloading large file on wifi and

- once during Youtube: the first sign was, the display didn't rotate automatically (while activated the corresponding option), then during tries to make it rotate, suddenly it restarted.

I recommend the following tests, each at more than 5 meters from the access point (or at less than 5 meters, but with a wall in the signal path):

- downloading ~ 4 GB isos (e. g. Debian image) with Android stock browser

- playing Youtube videos (high quality!), preferably min. 15 minutes long video, perhaps with some manual skips in the video
[ZTE Grand X V970] tlac:
That widget sounds dangerous for me. Uninstall it, reboot your phone and try again your repro steps.

ZTE Release ofifcial 4.1 for U970(wich only different from V970 is smaller ammout of ram and Single SIM slot):

http://www.zte.com.cn/cn/products/mobile/services_support/
[ZTE Grand X V970] bgcngm:
Hmmm... incomplete information. :p U970 is Tegra2 based, meaning that the ROM is completely useless for us.
[ZTE Grand X V970] HidEaL:
This has happened to me, but it is very random and I don't believe it is related to the Wi-Fi being on or off... If i had to guess, it seems to be related with the messaging app (which, to me at least, is the only significant problem with the current JB ROM).

Did both your tests (altough with the chrome browser) + testing xbmc remote for a long time, and 15 or so meters from the AP and with several walls, and nothing. Zero problems.

I'd like to raise an odd question:

My phone seems to be "communicating by itself" a lot. For example, when I'm at the computer, it does that interference noise on the speakers a bit too much

when I'm not sending or receiving messages or calls.

I don't recall this happening with any of the previous ROMs. So, the odd question is: Could this be problematic? :rolleyes:
[ZTE Grand X V970] anglergab:
I've uninstalled the Wifi High Performance widget, rebooted the phone, and watched Youtube videos.

The problem appeared, connection speed went to 0 Mbps.

I've made numerous reboots, and don't see any installed apps, which could cause this behaviour.
[ZTE Grand X V970] czullo:
Any ETA on release Bruno ? I see that there is changelog already but no working link :)
[ZTE Grand X V970] bgcngm:
Wait for the next release and then do a clean install... and don't install that app. :laugh:

It should be out soon, probably tomorrow. Just waiting for some Polish translated strings.
[ZTE Grand X V970] anglergab:
I've found two errors in the logcat, these appear right after the wifi connection is made:

- WifiStateMachine: Failed to set country code hu

(hu: Hungary), however the phone language is English

- WifiStateMachine: Failed to set frequency band 0

I've renamed /etc/wifi/wpa_supplicant.conf, to make the system create a new. But it doesn't made any change, the wifi passwords are not lost.

Bruno, where are the wifi credentials stored?
[ZTE Grand X V970] tlac:
I got same errors though I used morelocale2 with HU locale.

Anyway I don't have any longer experience with JB. I had other problem and I downgraded to 3.1

[ZTE Grand X V970] lurkerPL:
From what I know, LuHash is working on translation. :)
[ZTE Grand X V970] anglergab:
I got to know from another forum, that ICS has a bug in its wifi stack, which appears only if access points with certain chipsets are in range (!). So it can happen, that I haven't experienced the error before, but one of my neighbours installed recently an access point with a particular chipset, and the error appeared.

I think this could apply for JB, as well.
[ZTE Grand X V970] mmichal2:
You said it was ok with ICS?

Can you give us some details on AP model with problems?
[ZTE Grand X V970] anglergab:
Yes, because it depends on all of the APs currently in range, not only from my/active AP. So, it can happen, that at an other location, the wifi is absolutely OK either with JB or ICS.

(Don't forget, APs in range can change at a particular location in time.)

I don't know the model/chipset of all the APs currently in range, so I can supply info about my own AP only:

Belkin F5D7230-4 6000 with firmware F5D7230-4_US_8.01.21, and Boot Version v1.01.
[ZTE Grand X V970] LuHash:

Hey bruno , apparently one of my friend phone got bricked while using your ROM, and he says that he need the default preloader.bin for the JB so at least he could boot into recovery and flash the stock ROM, could you upload that? a lot of thanks :highfive:
[ZTE Grand X V970] gerstavros:
tell him to flash the preloader etc from ics. They are in bruno's recovery package
[ZTE Grand X V970] bgcngm:
I'm sorry to hear that. I must say that the problem was caused not by the ROM itself, because it is exactly the same as stock V970M Indonesian ROM apart from some modifications (which would never cause a brick). Your friend may have tried to flash CWM recovery and

wrongly

flashed the phone with V970 preloader. That's really a problem and he shouldn't have done that.

Now, regarding your request... I can't provide V970M preloader because I never got the full backup. If you have the same phone as your friend you can try to help him by creating a full backup (using MTK Droid Root & Tools). Let me know if you need further help.
[ZTE Grand X V970] anglergab:
Re: [ROM][16-02-2013] ZTE V970 (MT6577) custom ROMs (ICS / JB)

I changed the security of my AP from WPA2/WPA to WPA (AES), which is a bit less secure and it seems, the connection issue doesn't appear. However I experienced sudden wifi disconnects and after that immediate reconnects. At least manual wifi turn off and on (wifi restart) was not necessary in these cases.

I suppose the problems are NOT caused by Wifi High Performance widget, but much more either by kernel driver, wifi services or by access point configuration, chipset. Or by an unfortunate combination of them, which could explain why this problem appears rarely.

@Bruno,

I have experienced syncing problems with the standalone Google Calendar app. I had to clear the data of the app and the Calendar Storage app to make it sync.

It had sync problems right after rom install and now, after weeks of usage.
[ZTE Grand X V970] bgcngm:
I'm totally aware of that. Everyone else has/had the same problem. I don't know the reason why that happens, but as you mention, it can be fixed by clearing Calendar and Calendar Storage data.

I must say that this is not only our (V970 users) problem. I have also received the JB update on my MT6583 tablet and the same problem exists. I won't be worrying about that right now because it can be easily fixed.

unable to connect to my computer

First,as JB V1.0 mod installed,unable to connect to several softwares that used to work perfectly,like http://www.snappea.com/,thus i can not restore some of my backup to the phone.

Second,there seems to be some changes in settings between ICS and JB,unable to choose default location to install apps,SD or internal storage.And those apps stop working after moved from SD to internal storage which had never happened in ICS.

Third,settings stop working if i try scenes in display.

JB V1.0 is great indeed, hope it can be better.
[ZTE Grand X V970] bgcngm:
As you may understand, some applications that used to work on ICS can have issues with JB... The same happened when ICS was released and everyone was using GB.

I don't understand what your second problem is. I can move apps (the ones that support that feature) from internal storage to SD card and vice-versa without any problem.

The third problem you mention is also not a problem. You probably have chosen not to install stock launcher and that's the reason why Settings is crashing when you chose Scenes from Display settings.

It was reported on a Hungarian forum that the colors in the Camera app in v1.1 are incorrect. It can happen that the new 4.2 Camera app is not fully compatible with our sensor and/or color space.

Bruno, did you get that app from a Nexus rom?

Maybe both Camera apps should be included in next release: one for JB new camera functions and one for color accuracy. So everyone would be happy. :)

[ZTE Grand X V970] Pegli:
I am always afraid when I'm going to flash a new ROM: could you tell me what's the best way to do it (I'm with Bruno 3.1 now)?

1) Is it better to do full wipes before flashing?

2) What's the correct way to have the extended userdata partition enabled (I already have the latest MBR, EBR1 and RECOVERY)?

3) Other "hints"?

Sorry for my "newbiness"!!! :o

---------- Post added at 02:59 PM ---------- Previous post was at 02:50 PM ----------

1）yes,V3.1 is based on ICS while V1.1 is a JB rom,so full wipes should be done to avoid unnecessary problems.

2）flash the latest MBR, EBR1 and RECOVERY with flashtools,than boot into recovery,full wipes,install the rom,the Aroma installer will do the rest.

last,have not ever made any backup,but get similiar massage doing wipes,so i guess it is not a problem
[ZTE Grand X V970] bgcngm:
Both Camera apps are already included... If one wants the stock camera, just choose it during installation. Selecting stock Camera/Galllery installs it, selecting Google Camera/Gallery overrides that selection and installs the Android 4.2 app (taken from a Nexus ROM, yes). :D

I have wrote that already... If you are coming from ICS, do a clean install... that is, either by selecting wipe data / factory reset under inital recovery menu or by selecting the same option when AROMA installer is already running. If you have the latest extended userdata mod installed, then go ahead with the installation. Nothing more needs to be done.

That message you get during the backup is perfectly normal. It's just a warning, to tell you that there's no sd-ext partition found and no backup of it was done. ;)
