System UI Crash

Hi Guys,

I installed MIUI v4 latest version yesterday night till morning it runned well then when i went into about phone and clicked the status menu the screen went black and popped up an error saying android.process. then came lot of systme UI crashes which i cannot use the phone. Then i restored my phone to my previous rom mystic ICS. Now again i looked up there is a patch for V4 FIX4 so again i installed the MIUI V4 and installed Fix 4 and also ran fix permission. Now i checked again went into about phone clicked status menu but the screen again went into black and then popped the error android.process. I will update later if any more errors come out.
[AT&T Samsung Galaxy S II SGH-I777] ktoonsez:
That is a known bug in MIUI, I think they are working on it for next week but cant say for sure. So dont click that and u will be ok:D
[AT&T Samsung Galaxy S II SGH-I777] skatcat31:
Anyone know how to get the applications arranged alphabetically automatically? Just wondering, because it'd be an awesome feature.
[AT&T Samsung Galaxy S II SGH-I777] Fahimxda:
Thank you Ktoonsez for letting me know
[AT&T Samsung Galaxy S II SGH-I777] craigbailey1986:
You mean in a folder?? You can't do that anymore in ics miui.. only way would be to manually alphabetize the apps
[AT&T Samsung Galaxy S II SGH-I777] ronii1123:
Yes it works, I got it up and running and it runs great. I switched the boot.img with the cm9 boot.img, and switched the sec_touch key.kl with the cm9 sec_Touch key.kl, but honestly now that Ktoonsez got this working, its not necessary unless you really don't like Samsung haha.

Also, Ktoonsez, I actually went a night with out the force closes thanks to fix4. Your rock! I never lost faith in you
[AT&T Samsung Galaxy S II SGH-I777] craigbailey1986:
I haven't had another fc since yesterday so we will stay on today...
[AT&T Samsung Galaxy S II SGH-I777] gerguter:
Still going good with no FC's. The only thing I've seen was the phone rebooted when I tried to get out if maps. Other than that it's all good.
[AT&T Samsung Galaxy S II SGH-I777] Famos:
Ktoonsex is it possible that facebook and skype syncing can be fixed or is it up to miui devs?
[AT&T Samsung Galaxy S II SGH-I777] skatin707:
Like I said earlier (in the post you quoted), I'd like to learn from it and make some comparisons to this version of miui.

Also, the automatically alphabetized folders will be missed greatly :(
[AT&T Samsung Galaxy S II SGH-I777] ronii1123:
It applies themes the same honestly, from what I've seen I mean.
[AT&T Samsung Galaxy S II SGH-I777] ktoonsez:
That is up to the devs at MIUI unfortunately.
[AT&T Samsung Galaxy S II SGH-I777] skatin707:
Aren't their themes working? Ours are not.
[AT&T Samsung Galaxy S II SGH-I777] ktoonsez:
No, it would be the same unless he is using GB framework. He simply stated that he made the directory that allows you to apply themes, not that they 100% work.
[AT&T Samsung Galaxy S II SGH-I777] dan_maran:
Is anyone able to setup adhoc wifi with this miui? I keep getting wpa_supplicant errors and then the AP never actually comes online I've tried barnacle and the the built in wifi adhic hot spot. Note this is NOT tethering.
[AT&T Samsung Galaxy S II SGH-I777] ymcmbforever:
So is there a fix for the system ui fc ing
[AT&T Samsung Galaxy S II SGH-I777] ktoonsez:
Yes it is in the OP.
[AT&T Samsung Galaxy S II SGH-I777] skatin707:
Ah, it sounded like they had more luck with theirs.

Either way, my phone is freezing up a lot. The market works now that I updated it manually, but a lot of other apps are giving me issues. The USAA mobile banking app, Pandora, Soundhound, Cut the Rope experiments, NASIOC, and some others.

Are you guys having trouble with these? How are you getting them to work?

I usually have to pull my battery and reboot.
[AT&T Samsung Galaxy S II SGH-I777] ktoonsez:
My guess is that these are all apps that have not had any or little testing on ICS. And if they did, it would just be on Nexus's ICS and not AOSP, modded Sammy (like this one). You might have to wait for them to catch up. But hopefully someone has got a work aroound for you. I too have ahd a few issues with apps like Terminal emulator and a few others and just knew that if was becuase it has not been tested on ICS and will have to wait. You didn't restore with Titanium did you?
[AT&T Samsung Galaxy S II SGH-I777] skatin707:
No, I'm slowly remember what I had downloaded and I'm getting it back from the market. The backups I have on TiBu are from CM9 though, so I imagine some conflicts would arise.

That makes sense though. I keep forgetting how big of a change 4.0 really is. I have only been around since 2.2/2.3 so I'm pretty new.
[AT&T Samsung Galaxy S II SGH-I777] ymcmbforever:
Thanks bro u gonna be getting a beer soon :cool:
[AT&T Samsung Galaxy S II SGH-I777] ktoonsez:
Ya, I know how it goes, I have a few programs that I use for racing and they are not functioning right due to the changes in 4.0. We all just have to be patient and wait for the the 3rd party app guys to catch up:D. Even the simple program like GPS Status doesn't work properly, if anyone uses it, you will see it blank out the sat info and then come right back, and even restart the lock sequence too here and there.
[AT&T Samsung Galaxy S II SGH-I777] ktoonsez:
Thanks man!
[AT&T Samsung Galaxy S II SGH-I777] dan_maran:
Is anyone else not able to download applications that are "too large" through the google market/Play? I have a feeling it is a Play update issue. I can't find any settings in the Play application to rid this issue and I did check the downloads app in Miui ensuring Wifi only was off there also. the error is (196) which doesn't come up in a Google search.
[AT&T Samsung Galaxy S II SGH-I777] vijovame:
I asked here the same with no answer but for your benefit I found the problem, go to downloads app, menu, settings and turn off whatever is there, your market will work fine, let me know if worked.
[AT&T Samsung Galaxy S II SGH-I777] dan_maran:
Thanks. it did work. It would be a good little application if it actually worked like it was spposed to!!

Thanks again!!!
[AT&T Samsung Galaxy S II SGH-I777] vijovame:
You welcome!
[AT&T Samsung Galaxy S II SGH-I777] skatin707:
I answered your question, or at least the same exact question with that response.

My Gmail app disappeared lol. I don't know how or why.
[AT&T Samsung Galaxy S II SGH-I777] illathanyours:
Though we are kinda missing themes, I think i like the Sammy base here, and since my last post a few pages back fix 4 got the ROM running perfectly, I have noticed a few inconsistencies in the default theme like some popups and some settings menus, but not too serious.

Sent from illaphone.
[AT&T Samsung Galaxy S II SGH-I777] eortizr:
is there any workaround to get emoji icons back in the stock sms?
[AT&T Samsung Galaxy S II SGH-I777] IconRunner:
So what needs to happen to get themes fully working? Are we waiting on MIUI China to release something?
[AT&T Samsung Galaxy S II SGH-I777] ktoonsez:
Yes we are waiting for MIUI devs.
[AT&T Samsung Galaxy S II SGH-I777] skatin707:
Which I'm sure will not take long. That's one of the best parts of miui (its my favorite for sure). I'm tempted to try another ics rom in the mean time. I need a bit more stability while I'm at work.

Lastly, we really are lucky to have you tackling this project ktoonsez. Thanks again.
[AT&T Samsung Galaxy S II SGH-I777] skatcat31:
Anyone else having terrible GPS signal? It gets a loco then losses it and it's gone
[AT&T Samsung Galaxy S II SGH-I777] ktoonsez:
Are you using GPS status? Personally I think it is the program not behaving properly in ICS, as I have used tracking software for racing and the GPS is fine even though GPS status gives a 8/11 locked, then nothing, the 6/10 then nothing. Basically back and forth, back and forth.
[AT&T Samsung Galaxy S II SGH-I777] skatcat31:
Went back to kk6 modem and everything works, it's the leaked modem in my case. Kk6 is rock solid
[AT&T Samsung Galaxy S II SGH-I777] ktoonsez:
Good to here, I will try that with GPS Status and see if the back and forth thing goes away since I also have the leak in there too.
[AT&T Samsung Galaxy S II SGH-I777] dan_maran:
Ok so I dumped some logcats and this wpa_supplicant issue is a bitof a c0ck.

I am leaning toward a driver issue:

wpa_driver_nl80211_driver_cmd: failed to issue private commands

I'll try to look into it more tomorrow, but the results of the great Google machine are not that helpful.

Thoughts:

1. If someone would be kind enough to post an un-molested wpa_supplicant.conf that would be great as I am wondering what got touched by the tethering programs. It's in /data/misc/wifi/wpa_supplicant.conf

2. After that maybe try to FoxFi and see if it works for you? Or even the built in Miui Wi-Fi direct.

And some logcats are attached.
[AT&T Samsung Galaxy S II SGH-I777] dan_maran:
I'm also going to put this here:

http://code.google.com/p/android/is...=ID Type Status Owner Summary Stars&start=100

It's from the Nexus forum about a botched 4.0.3 broadcom driver...
[AT&T Samsung Galaxy S II SGH-I777] Fahimxda:
So Far So good

Hi ktoonsez

I am using the V4 MIUI rom after the Fix4 the rom is too good so far no crash everything works fine. Thanks for the rom. One more thing anyway will we get the contacts full picture when dialing or receiving calls. Thanks in advance.
[AT&T Samsung Galaxy S II SGH-I777] vijovame:
I'm waiting for that too...
[AT&T Samsung Galaxy S II SGH-I777] ktoonsez:
I think you are going to need to contact the maker of that app. They obviously havent tested with ICS or all the different flavors of ICS. They will be the only ones that can make a fix.
[AT&T Samsung Galaxy S II SGH-I777] ktoonsez:
I think that is in the works, but is going to be low on the priority list.
[AT&T Samsung Galaxy S II SGH-I777] ktoonsez:
I have not seen anything mentioned about that.
[AT&T Samsung Galaxy S II SGH-I777] dan_maran:
thing is that not even the built in miui wifi adhoc works. To me it looks like the driver is a bit borked, but I'll try contacting the devs.
[AT&T Samsung Galaxy S II SGH-I777] jasonemorrow:
I just used emoji font updater app. They're in black and white but works perfect.
[AT&T Samsung Galaxy S II SGH-I777] ronii1123:
@Ktoonsez

System UI ForceClose after using the toggle in the status bar to switch from 2G-3G :( With Fix4 included so I hope that helps.

Afterwards everything went fine, the Status Bar came back and it all was working okay.
[AT&T Samsung Galaxy S II SGH-I777] ktoonsez:
This is a known issues with MIUI, they are missing some functions to call that option. Bottom line is dont use it till they fix it.
[AT&T Samsung Galaxy S II SGH-I777] ronii1123:
Oh, apologies then. Didn't realize it was a known issue
[AT&T Samsung Galaxy S II SGH-I777] skatcat31:
So day two of kk6 and I'm still solid. Anyone else?
[AT&T Samsung Galaxy S II SGH-I777] dahlem:
Same here everything works and it is awesome! The only problem I have is gps takes a bit to "find me" initially, after that it is good . . . great job Ktoonez!!!
[AT&T Samsung Galaxy S II SGH-I777] skatcat31:
Right, so had anyone gotten the 4g apn to stick? Mine keeps defaulting back to the 3g one... Maybe I set it up wrong?
[AT&T Samsung Galaxy S II SGH-I777] dahlem:
The only one I have showing is the default ATT - wap.cingular is there supposed to be another one too?
[AT&T Samsung Galaxy S II SGH-I777] skatcat31:
That's the default 3g access point. I got the 4g one to stick and work now.

Settings that need to be changed in the new apn you create are literally just name: phone apn: phone
[AT&T Samsung Galaxy S II SGH-I777] skatcat31:
Thought I'd weigh in. My phone the wifi direct works fine. I connected my old psalm TX to it and everything was dandy.
[AT&T Samsung Galaxy S II SGH-I777] dahlem:
can you give me a screen shot kinda confused
[AT&T Samsung Galaxy S II SGH-I777] skatcat31:
here:

It's a little ugly, but the only options you have to change are the first two to say "phone" without the quotes. LEAVE EVERYTHING ELSE ALONE! then save, and set.
[AT&T Samsung Galaxy S II SGH-I777] dahlem:
Are we able to do a backup of this and restore? Thought I remember reading at some point that custom kernals you were not able to do that.
[AT&T Samsung Galaxy S II SGH-I777] ktoonsez:
Everything is working fine.
[AT&T Samsung Galaxy S II SGH-I777] IconRunner:
Can anyone confirm if the 3-way boot is working? I tried the 4-way a few days ago and it sent my phone into a bootloop.
[AT&T Samsung Galaxy S II SGH-I777] dahlem:
Yep it works getting to it from the power button not from the reboot toggle, at least on my phone . . .
[AT&T Samsung Galaxy S II SGH-I777] ktoonsez:
Crap! Sorry about that guys, I sometimes forget about post #2. 4 way reboot has been deleted out of Post #2. I moved the UCLC2 modem and the new 3-way reboot down to post 2. In the future I will include the 3-way reboot in the ROM. I did not do it last week since I was dealing with the SystemUI crashes.
[AT&T Samsung Galaxy S II SGH-I777] skatcat31:
Incase you're wondering, if you set an APN and it messes up, there's a restore default button that will restore the old wap.cingular APN.
[AT&T Samsung Galaxy S II SGH-I777] iflipsamurai:
APN

this is what i did and it worked for me i hope this helps :D

APN Name : ATT

APN: wap.cingular

Port: 80

Username: WAP@CINGULARGPRS.COM

Password: CINGULAR1

APN type: default,mms,supl

leave everything else the same

go to phone and dial

*#*#4636#*#*

click "phone information"

press "menu"

Select radio band

choose band: mine is USA band

put in Airplane mode for 20 seconds

you should be good to go :cool:

this worked for me and hope it works for you guys
[AT&T Samsung Galaxy S II SGH-I777] skatcat31:
That's the 3g WAP connection, not hte 4G HSPA+ access point...

4G HSPA+ APN:

APN Name : phone

APN: phone

Port: [leave alone]

Username: [leave alone]

Password: [leave alone]

APN type: [leave alone]

It'll grab the information from your sim card at that point. Just save and select. Then run a speed test. You should either get the same speeds, or in a market that supports HSPA+ fully, great speeds. THIS IS THE APN IN THE DEFAULT ROM.
[AT&T Samsung Galaxy S II SGH-I777] dahlem:
Is making a new APN necessary? I'm showing 4G and have good speeds with the original APN
[AT&T Samsung Galaxy S II SGH-I777] skatcat31:
You'll get at most 3Mbs as it's limited to that at the tower using that APN. The new one, in some markets, leads to much better speeds. Try it out and see if it works, or if you're happy ignore it an move along.
[AT&T Samsung Galaxy S II SGH-I777] dahlem:
So that is the "Phone" APN you showed earlier correct?
[AT&T Samsung Galaxy S II SGH-I777] skatcat31:
Yes.

Is anyone randomly not able to send texts?
[AT&T Samsung Galaxy S II SGH-I777] dan_maran:
I think it could help some, but this is with the default APN settings ;-)
[AT&T Samsung Galaxy S II SGH-I777] skatcat31:
And still less than 4g speeds. Guess i misread the mbs of 3g doing my research. Anyways i cant send texts suddenly. Even after a factory reset
[AT&T Samsung Galaxy S II SGH-I777] dan_maran:
I still don't get what 4g speeds you're speaking of....:rolleyes:
[AT&T Samsung Galaxy S II SGH-I777] ktoonsez:
I finally got the CRT off working, I will include it in the next update or if you guys are really dieing for it, I can make a CWM flashable file:D
[AT&T Samsung Galaxy S II SGH-I777] afrojoc:
If you would kindly... :))
[AT&T Samsung Galaxy S II SGH-I777] ktoonsez:
Just a little warning, it does act goofy sometimes, but for the most part is working:D
[AT&T Samsung Galaxy S II SGH-I777] afrojoc:
As long as i dont run into a bootloop ill be alright!

Thanks by the way
[AT&T Samsung Galaxy S II SGH-I777] ktoonsez:
Alright, here is the CRT off, also put it up in Post #2

http://www.mediafire.com/?rncbvnkbvdjk6hd
[AT&T Samsung Galaxy S II SGH-I777] afrojoc:
Works great! Thanks a lot ktoonsez! You da man.
[AT&T Samsung Galaxy S II SGH-I777] vijovame:
Any way to get proximity sensor working? Thanks
[AT&T Samsung Galaxy S II SGH-I777] ktoonsez:
? They already work.
[AT&T Samsung Galaxy S II SGH-I777] skatcat31:
Sadly my SMS application died, so I'm going to have to reflash stock... FUN. Not.

EDIT: all fixed. Reflash to stock, reflashed CWM, and reflashed MIUI all after fixing the message center number. VIVA LE STUPIDITY!
[AT&T Samsung Galaxy S II SGH-I777] vijovame:
How!? Here isn't working
[AT&T Samsung Galaxy S II SGH-I777] ktoonsez:
I guess I dont understand the question. If I make a phone call and put it to my ear the screen turns off, I take it off my ear it turns on. Urs should do that too, nothing to change, it should just be working.
[AT&T Samsung Galaxy S II SGH-I777] vijovame:
Nop, in my phone it just turn off the screen a few sec later automatically when I placed a call and to turn back on I need to press power button, its like old windows pocket pc!
[AT&T Samsung Galaxy S II SGH-I777] Karashta:
Mine also works like this ktoonsez. Idk why his wouldn't be working

sent from my magic shiny box using the tap tap tap
[AT&T Samsung Galaxy S II SGH-I777] skatin707:
Same here, mine worked on the 2.3.30 build.
[AT&T Samsung Galaxy S II SGH-I777] SeanHacker:
its looking good over here Ktoonsez. :D
[AT&T Samsung Galaxy S II SGH-I777] ktoonsez:
Thanks buddy:D
[AT&T Samsung Galaxy S II SGH-I777] skatcat31:
I know it does this if I have it on speakerphone or headset, but that's what the default rom did too IIRC. I'll do som comparisons tonight and report what I find, or if I'm just remembering wrong. As it stands I'm on my way out the door for work :(
[AT&T Samsung Galaxy S II SGH-I777] ktoonsez:
The SystemUI bug is on the official list of bugs, hopefully they will get to it this week but at least it is on the list :D

See link (its number 6)

[AT&T Samsung Galaxy S II SGH-I777] skatcat31:
Yay. If I leave my wifi on when I don't have a connection, it crashed the ROM and I have to reboot. Anyone else getting this? It happens while I'm driving for some reason.
[AT&T Samsung Galaxy S II SGH-I777] ktoonsez:
Only before I released FIX #4. After that it has been smooth sailing and I do have wifi at home, work and my favorite lunch spot. So it is always on and loosing one and getting another. Maybe wipe dalvik and cache, I doubt it will help but worth a try since it doesnt hurt the ROM. One question though, do you have any 3rd party wifi programs, like teathering software or anything? I wonder if your APN's could be doing something too?
[AT&T Samsung Galaxy S II SGH-I777] gerguter:
MIUI v4 with Fix #4

ktoonsez, I gotta say that after flashing Fix# 4 it has been smooth sailing. I haven't had a FC since I flashed it. Been using it at home with the cell booster and at work and on the road. All is good. Thanks again! :cool:
[AT&T Samsung Galaxy S II SGH-I777] nuuits:
DL link isn't working?
[AT&T Samsung Galaxy S II SGH-I777] skatcat31:
No, i had to reflash fix 4, for some reason it didn't stick as it turns out.
[AT&T Samsung Galaxy S II SGH-I777] ktoonsez:
Glad everything is going good:D
[AT&T Samsung Galaxy S II SGH-I777] ktoonsez:
Cool, glad you got it figured out.
[AT&T Samsung Galaxy S II SGH-I777] skatcat31:
Yeah, that was loads of fun to do while driving XP
[AT&T Samsung Galaxy S II SGH-I777] dan_maran:
Is there any way to manually adjust the screen brightness beyond the slider with your kernel?Like the Siyah kernel? I ask because I not that the screen is constantly eating about 65-75% of the battery and I have a black wallpaper and if I am inside I will turn off the screen auto brightness but it still chews it up..

//Edit: my init scripts for brightness didn't seem to make a difference

Thanks again this ROM is otherwise working great!!
[AT&T Samsung Galaxy S II SGH-I777] skatcat31:
The reason the screen kills like a monster is the fact that we have a small battery. The screen itself, even with the back light fully turned off(so the screen is unreadable and fully black) still drains the battery 98%, it's the actual hardware. The farthest i was ever able to bring it down was to 70% during a full charge usage, but you literally can't see the screen. The levels they are at now are just bright enough. It's the actual screen. BUT DARN ITS PRETTY!:p

EDIT: also the brightness levels are built into a database. If you want you can go looking for it. IIRC correctly it's somewhere in the build.prop, but I'm not sure. Last time I manually changed it was on CM7, and that has loads of kernel customization. I wonder if in MIUI it's hard coded into the kernel like it used to be? ktoonsez, input?
[AT&T Samsung Galaxy S II SGH-I777] ktoonsez:
I am pretty sure it is controlled by the ROM/props and nothing is hardcoded into the kernel but I will look in the source code to make sure. But you are right, it is just a big screen and it will always be the biggest battery chewer!
[AT&T Samsung Galaxy S II SGH-I777] ktoonsez:
Just to add a little more on the battery topic. I was just talking with trailsrider1 abou this last night where, there is a known issue with 4.0.3 and battery "chewage". Hopeully MIUI will upgrade to 4.0.4 soon as it does correct some of this higher than normal battery usage. As for myself, I am very happy, I can make it 2 days without charging with moderate use.
[AT&T Samsung Galaxy S II SGH-I777] dan_maran:
Thanks for the heads up :-)
[AT&T Samsung Galaxy S II SGH-I777] skatin707:
I can't wait for the upcoming update it sounds awesome.

I freaking love this swiftkey 3 beta!
[AT&T Samsung Galaxy S II SGH-I777] ktoonsez:
I was up to 3am, tried about 40 combinations and no go! They really broke something good, basically it can't get access to the /data directory which of course causes all kinds of crashes. Something to do with there new su. I will keep trying today, but not looking good.
[AT&T Samsung Galaxy S II SGH-I777] cjsabaki:
Looking at adyscorpius thread, latest miui build is buggy, he's having hell too n skipping this build, Wiui has updated to b4 but its 2.3.2 running OK, bit hotter battery temp, SMS fails first try and android os is eating more battery than I like, needs sum app control tweaks.

Checked all over miui china site for possible link to new beta v4, no luck, check miui.au n see if they have a better build??
[AT&T Samsung Galaxy S II SGH-I777] cjsabaki:
Just for info, search xda for xj's miui thread, always the latest info, addon's n stuff, cameras, keyboards u name it!!

P.s. new 4.0.4 ics is out, read thru the change log, many kernel related fixes.. might not have our screen wake issue... see paradoxxs hydrogenics thread on I9100.

Got the new 4.0.4 build w flash n test for screen on bug n report.....
[AT&T Samsung Galaxy S II SGH-I777] ArtificialMusik:
how do I get into recovery? Not sure about this CWM, just wanted to make sure. I've stuck at a Xiaomi screen for 30 mins
[AT&T Samsung Galaxy S II SGH-I777] cjsabaki:
Hold power n volume up and down at the same time.
[AT&T Samsung Galaxy S II SGH-I777] ktoonsez:
Ya, I have been checking them all out, everybody is having issues like me. miui.au stiill has nothing. WIUI is based on something different so that one didn't really help me and is based on 2.3.2 anyway. I'll keep digging:cool:
[AT&T Samsung Galaxy S II SGH-I777] cjsabaki:
2.3.9 ril files are fragged... Either mistake or miui china is trying sum thing new... Not sure just read several devs talking bout the build, wait a week n see if new samsung base is released....

Crap..... still screen wake w 4.0.4 Hydro rom....

Damn..
[AT&T Samsung Galaxy S II SGH-I777] cjsabaki:
Hhhhmmm, use latest CM9 libs ril files only in the 2.3.9 miui to fix maybe??? Per paradoxxx n adyscorpius.
[AT&T Samsung Galaxy S II SGH-I777] ktoonsez:
I think I already tried that, I can't remember as I went thru 40 tries:rolleyes:
