Screen rotation

I used su -> /system/bin/sensorcalibutil_yamaha to fix the rotation lag on my epic and it has caused serious issues. I can't post in the thread this originated it. Sorry. Still new to tapatalk. Many of my apps now are stuck horizontal and upside down. I've restarted. Enabled/disabled everything I can think of. Tried GUI calibrated. Used sensorcalibutil with phone orientated on all sides. . Turning off screen rotation keeps most menus and such vertical but the dialer is now useless in the horz upside down position. Running truly epic rebirth rom.

I had the same issue but a simple reboot fixed out for me. Good luck! I hope this helps.

Hey. I had the exact same problem after I used the terminal. but after rebooting a few times the rotation started working perfectly fine just like the day i got the phone. I Hope the same happens for you.

I am taking absolutely no credit for this.
Here is what i do.
I paid for Root Explorer. I am sure you can find a similar program. Here are the steps...
Navigate to data/system directory.
Find the file ms3c_yamaha.cfg and rename it putting a .bak at the end.
Close Root Explorer and reboot the phone.
This should recreate the File and then you can run your sensor calibration method.
Works every time.
Hope this helps.

Found a suggestion that worked for me in another forum. Terminal the commands as normal then lay flat on its back with keyboard open. Then stabilize with a finger and hit enter. Close terminal,power button for a few seconds and power back on. All was perfect after that.
Thx for everyone's responses

I think you may have missed the portion where you have to shut the screen off immediately afterwards. I have 2 epics with multiple roms tried and loaded and this method never failed me. I never had to open the keyboard. I dont see how that works seeing as how your stabilizing it with your hand anyways? But then again I ran the calibration as soon as I flash...

Assuming you followed directions from jbuggydroid here, did you get a confirmation message in the terminal emulator saying that the screen was calibrated?
Did you exit the program, then turn off your screen and turn it back on?
When you calibrated the phone, did you lay it on a flat plane, like a table?
If any answer to those questions is no, I would say to try it again and just make sure each step is followed.

Lost ROOT??

ok creepy. I had root access this morning. Everything was fine...
I rebooted my xoom recently to check out a new boot animation, and now I've lost root. Every root-required app I open says I've lost root!
Still running 3.0.1 ... so it didn't install any OTA that I know of. I didn't accept any OTA's anyways
This is on the WIFI Xoom 3.0.1 with Tiaman 1.3.2. Anyone seen this happen before where you just randomly lose root? I've rebooted 3 more times.... still nothing. What the hell?
EDIT: Things I've changed since this morning when I had root:
- new boot animation zip file - no troubles there
- installed CircleLauncher widget ...
- usual browsing, checking emails, gtalk, tweetdeck etc...

ok weird as hell. I think my SuperUser was broken.
Ran the following commands and root is back. Rebooting now to see if it stuck...
adb remount
adb push su /system/bin/
adb shell ln –s /system/bin/su /system/xbin/su
adb shell chmod 4755 /system/bin/su
adb push Superuser.apk /system/app/

guess nobody has a similar issue. odd indeed.
I'm back together being rooted and now all of a sudden my battery indicator light works as intended (white while charging, green when full)
still have the same version and all. feels like an update was somehow pushed though.

For sure a great story...
Sent from my Xoom the way it should be, rooted and with SD card.

Glad you got SU back,,,and wish I could help, but you would know if a update was pushed as it would come across your screen and you would be notified. Just sorry that the many people on sites like these have the knowledge to help but they would rather sit back and flame about how much they know and others dont.
Anyway keep the adb commands handy or use the one click method it worked for me on more than a couple of occasions with a few tweaks of mine.

Well this has never happened to me. My battery indicator was fixed as soon as I installed Cybertronic. Works great now. Good luck and if this ever happens again, look into it a little more for the next guy who gets screwed over like this unexpectedly.

so weird, xoomfaq.com says the battery light only shows when the xoom is powered off. so I guess it was doing the right job before? weiiiiiiird.
so yeah SU works fine now. no clue how it happened. either kernel manager 1.2.0 or the third thumb keyboard beta!

Acer Solution for WiFi Issue

Anyone experiencing the endless loop WiFi situation, here is the solution from Acer level 2 support.
The resolution is to do 2 hardware resets in a row. While the tablet is on, and you are at the homepage, use a paperclip and push it into the hole under the full sized USB socket to reset the tablet. Allow the tablet to boot up and when it is completely restarted and you are back at the homepage press the reset button one more time.
When the tablet comes back up again you will have WiFi again and you should not have any problems going forward.
BTW, this has only been tested and verified on a STOCK tablet.

I have stock 100%. This did not work for me nor several others.

I'm trying this right now as this problem just reared its ugly head... I'm not exactly stock, but I'm back to a stock Acer ROM after dabbles with VirtuousGalaxy (loved it) originally in hopes of getting the official OTA update. I'm so mad too, cuz I was just about to finally buy Titanium Backup so that I could play with ROMs more easily and not have to reinstall 100+ apps one-by-one...
Luckily, I took so long to ramble that all out that I'm almost done with both resets...
Survey says... no go... it's still just looping from Obtaining IP Address back to reconnecting, and I've tried connecting to multiple networks, even a mobile hotspot, even totally reconfiguring my router and to no avail... amazing how useless this thing becomes once it's severed from the net.

What the hell i have the same issue. This morning perfect tablet. This afternoon while at work turned into a POS...
Question?
If i hit the reset button do i loose all apps and stuff? I really dont want to loose anything since i have SOOO many apps I cant get back for free (amazon) and or all the 4-5 weeks of game play... yes constant game play including my kids.
update...just googled and YEP loose it all. Looking for other solution. WTF... Soo pissed right now

You are mixing up a factory reset with the normal hardware reset.
The hardware reset by using the reset "button" on the bottom right of the tablet just reboots the hardware, very much like the reset button on a standard PC. Your apps and data will not be touched.

if you could get hold of the .40 update, it contains a file called fixwifi which could possibly help you.

Or, if you are rooted,
- Switch off wifi in the settings.
- open a shell and remove those two files:
$ su
#rm /data/misc/dhcp/dhcpcd-wlan0.lease
#rm /data/misc/dhcp/dhcpcd-wlan0.pid
- and switch wifi on again.
It might help. :-/

why dont you just root and back up your games and apps with titanium...than un-root it...

why not

Thanks and i could be. I always thought when hitting reset like that was resetting the device back to stock. I trust you guys at this stuff. I went technology stupid a few years back.

To be honest I have lost all faith in my rooting ability. See above post on why.
Would love to get back into rooting things (MT Slide, MT4G, A500) but knowing my past experiences i would mess things up so bad its not save able. I was out of a phone for a week and had to pay someone to fix it. I dont think i can go through that again
Update: Cool it worked I had to turn off the lock screen first and after 6 resets I still have everything. Thank you for your patience and time.

So weird to see this thread... I had this exact problem last night. I did a wipe and reinstall,and everything fixed itself. I'm glad you posted this because I figured it was a software problem. I'll give it a shot the next time it happens.

i Can confirm this worked after the second reset.... rooted using virtuous Picasso 1.0.8

All I have to do is forget the network and then just connect again...works every time for me

I ran into the wifi scanning loop a couple of days ago.
It seems a bit extreme to go the hardware reset route.
I suspect most of us following the dev forum are already rooted and can do something similar to what I did.
I poked around with root explorer, blew out the dhcpd files, and hot booted.
Wifi is fine now.

rebooting isn't necessary if you turn off wifi before deleting the files. in the process list there are two dhcp related processes
$ ps | grep dhcp
root 177 2 0 0 ffffffff 00000000 S dhcp_sysioc
dhcp 22869 1 900 444 ffffffff 00000000 S /system/bin/dhcpcd
i guess the dhcp_sysioc is controlled by android and that process in turn starts and stops the unix dhcp process. both are stopped when wifi is switched off in the settings.
when it's stopped the dhcp files are left. so either the dhcpcd process is killed with -9 or it doesn't handle the signal properly...

Hardware rebooting twice worked for me. I am running Picaso version 1.1.0 HC3.1
Thanks for all the suggestions everyone!

This worked great. Also you can use root explorer to navigate to same folder and remove thase files without adb

I have tried this out on 2 machines we have an it has worked and I have not looked back since. I don't understand why someone with a stock unit would have an issue but you never know.

I just got this tablet yesterday. I flashed Acer_A500_4.010.22_COM_GEN1 from http://forum.xda-developers.com/showthread.php?t=1159443.
Last night and today WiFi worked great. Today out of nowhere I cannot connect to WiFi. It loops from obtaining IP address to reconnecting etc.
I tried to 2x reset method, this did not work.
I did root last night, but i didn't install terminal emulator or root explorer yet. dammit. so i'll have to get the APK's from my phone and put them plug the tablet into my desktop to get them.
Hopefully manually deleting the dhcp file fixes it.
I would really love the latest OTA that fixes the wifi issue
EDIT:
I got term.apk and pushed it, ran it, manually deleted the 2 files as mentioned, all working...for now.

[Q] CM7 dual boot on NC: The screen will start to move on its own

I found that every so often my screen will either start to move on its own or will no longer accept my finger press's. I can fix it by hitting the power button and then turn it back on and it will read again. is there a way to fix this so I don't have to press the power over and over again?

I've had this same problem with my Nook Color (which is about a year old). I solved it by installing a newer version of the ROM I was using. If you still using the stock software that came with the device try doing a factory reset as this problem seems to have evolved and wasn't inherent to the device. Good luck!

Well odd thing I was messing around with Themes this weekend and the problem disappeared. it doesn't move like it was, but now I find that some of the more intensive games seem to slow down a bit now. Doesn't happen often but enough. Hopefully all this completely disappears once ICS is stable

[Q] Permanently Disable Wifi?

I seem to be having issues with every ROM concerning cell signal. I can't get 2G/3G signal at all, and can only get 4G signal when in the right area (as expected).
I think it has something to do with my malfunctioning WiFi. It constantly just tries to turn itself on, with no success. I'm quite positive that my WiFi is broken due to hardware problems (internal coaxial cable, etc) as I have flashed several ROMs and radios with no positive results in order to try to fix it. I've even tried unrooting and returning back to stock.
What I was wondering is it possible to permanently disable WiFi on the MT4G so that I can try to get around this issue?

You could flat out take out the wifi radio chip.

Ah, THEindian. To what do you I owe you for the grace of your presence?
The problem with that is really just that I don't have the torque screwdrivers or a phillips small enough to disassemble the phone. I was looking more for a software "fix". I'm not really even positive that the WiFi has anything to do with causing issues with the 2G/3G reception.

Delete the WiFi Modules from system/libs modules folder and it will disable delete Wifi

Yes. That's the wifi module.

So, I renamed the file to have a .bak extension. It did accomplish what I wanted to (disabling the wifi and preventing it from turning on constantly) but it did not fix the real issue of not being able to recieve 2G/3G signal. I don't know what else to do.

Yes, I am a T-Mobile US customer. APN settings should be correct according to the support docs on the T-Mobile site. I've made a few other adjustments to this ROM's build.prop to the wifi settings. Set it to use eth0 as the interface for a while rather than wlan0. Still hoping there's a software fix for this mess.

That seems to be the only option I have left. I just fear that I'm going to break something and then revert back to using an old Samsung Gravity because that's the only other GSM phone I have. I'll have to find a place that sells small enough torque screwdrivers as well as a phillips head small enough to take off the screw under the "Void" sticker.

Well you could disable on build.prop

Ebay.

I'm actually thinking about using my friend's old unlocked iPhone 3GS for a while (maybe they even refarmed the 1900's around where I live to get 3G by now) until I can scrape up the cash to get a One S.
I'll put the whole story of my phone's downfall here to see if somebody can figure out what it is, or maybe even try to prevent it happening to others.
Bought the phone back in February 2011, and it worked perfectly fine up until April 2012. During this time I was running a Sense 4.0A ROM (can't recall the name) and my phone had died from battery drain. When I charged it up and turned it back on, my WiFi was no longer functioning. It would just repeatedly attempt to turn on and switch itself off again.
I flashed several different ROMs and radios to try to see if I could fix it. No luck. I then suspended my line from T-Mobile's service from June 2012 up until 2 weeks ago. When I had my service restored, I no longer had 2G/3G connectivity. By this, I mean when I'm in an area that does not have 4G coverage, I'm greeted to a "Limited Signal" message and cannot send texts or make calls. If the area has 4G coverage, I can do everything as normal with no problems.
I flashed several other ROMs to see if it was just an issue with that, no luck there either. I then just proceeded to unroot and return to stock. I was never successful in turning the S=ON (none of the guides posted worked) but did lose root privs and bring myself back to Stock Froyo.
None of this has worked so far. Since then, I've re-rooted and reflashed cnote's ICS MIUI build and here I stand.
