[Q] Accelerometer problem - Acer Iconia A500

Hi guys, i have a problem... After a OTA 4.0.3 update my g-sensor won't work! I did a hard reset no effect... Downgrade to 3.2 - no effect... Guys plz, i really need help!

I had the same problem
After doing the OTA, rotation was down... i've rooted my tablet, and install a custom rom (FLEXREAPER-R14-1.033.00_1.031.00-ICS) but the problem was still there.
After many and many reboot/flash... i've decided to flash a last time the Flexreaper rom. After booting/configuring (problem still there of course), i've flashed with the light :
A500-1.031.00-LIGHT-WITH_ICS_BOOTLOADER 180MB.zip
from there : http://forum.xda-developers.com/showthread.php?t=1622425
But without wipe, by keeping the old configuration from Flexreaper rom. After flash, i've keeped my tablet horizontaly on a table during all the installation to keep the sensor in the same state during all the installation. At the first boot, i've the message "performing update xx/60" from ICS. Wait until update is finished.
Still without mooving the tablet, i've done a reboot ... and it works !
Then I've done again root/bootloader/recovery/kernel
And without wipe, i've flashed again the Flexreaper rom (tablet still on the table)
First boot and again a "perform update xx/68"
Reboot again and still without moving the tablet and it still work now !
To be sure, i've done a full wipe, and reinstall the rom. Rotation was blacked again, i've done alle the stuff below, and it works ...
As i said, i don't know if i'm lucky or not... But on my mind (i'm not a developper... so it's a full noob thinking) when ICS perform the update, it lock the sensor in his actual state...
Sorry for my poor english, but i hope it can help...
Edit : After few more reboot, the accelerometer crash again ...

After lot of more tests, i've found something interessing, that's my methode :
The first steps are maybe useless, i've found a solution after doing that, but i haven't test yet without:
*********************************************
Probably useless
*********************************************
1°) Boot in recovery
2°) Full wipe
3°) Flash rom from here : http://forum.xda-developers.com/showthread.php?t=1633907
4°) Reboot
5°) Configure account / settings
6°) Reboot in recovery
7°) Wipe data
8°) Flash rom from here http://forum.xda-developers.com/showthread.php?t=1517181 (or maybe other custom rom, i don't know yet if it works with others)
9°) reboot
You'll see the "performing optimisation" step and ICS will start.
Normaly, in my case, flip screen doesn't work, and wifi nether.
10°) go to "parameters/backup and restore" and do a factory reset from ICS
11°) Reboot
At this point, wifi is working but no screen rotation.
*********************************************
/Probably useless
*********************************************
Now the points i think usefull
12°) Lock screen with the top switch
13°) Reboot : Do this with your tablet on a table for providing mouvments
14°) when all is started, unlock screen with the top switch
Rotation should work.
Do the step 12->14 on every boot, it works for me.
I've also try (only one time... i've no more time to do more tests) to do steps 12->14 with the tablet in my hands, and it also works.
I've try to reboot normaly without locking screen, rotation was blocked again ...
I'll try tonight by doing a full wipe and flash a new rom without doing the steps 1->11, i'll let you know.
I hope it can help ! please tell me

On another forum I came to a fix that seems really strange but it worked for me and it's quite simple :
Turn off the tablet, then move repeatedly the rotation lock switch to on and off few times. Power the tablet up.

ty
Ty guys, but all ur suggestions won't help me...:-( any more ideas?

[Q] motorola defy does not start

Hi ..
I had updated defy to the latest cnmod nighty version. ( 110410 ). Eveerything was working fine. i played with the phone for the entire day. video acceleration was awesome and played gt racing.
Suddenly there was problem with wifi connection. I decided to restart the phone. Choose the reboot menu . and now the phone is stuck with the moto logo on startup. Nothing happens after that.
When the bluelight blinks after the android menu , when I press the down button , I get android bootmenu v1.0.5 (By cynongen defy team and galaxy) ,
i was not able to do anything from here. It has these menus :
1)Boot : boot is set to 2nd init
2)cpu settings
3)recovery : in the recovery menu , If i choose latest recovery or stable recovery , I get error in /system/bootmenu/script/recovery.sh (Result: no such file or directory) , and when I choose stock recovery , the phone restarts and is stuck with an exclamation mark )
4)tools: I could understand what to do here.
When nothing did work , I pressed both up and down button after changing boot to normal. there i cleared some cache or something , cleared everything that I could.
After all this my phone is in the same place. A moto logo on startup.
Please can someone help me . This is my first android phone and also the first costly phone I bought and I did something nasty on the first day itself.
i am a normal end user who knows nothing more than gui.
thanks in anticipation
hey
flash a stock 2.2.2 with RDS from bootloader
you gonna need latest defy drivers for windows plus a stable froyo i guess
google this "how to unblick a bricked defy"
let us know what you do and what changes
are you sure this is a case of bricked defy. I had read in many places it is very difficult to brick defy.
its not bricked
but that is what you need to search for to get the solution
i did so too
What "Natsikap" said.
Clear Data/Cache.
Flash Official Froyo 2.2.2 using RSDLite, Use your region correct Froyo (If you are from India use SEA15 Stock ROM -Get it here http://forum.xda-developers.com/wiki/index.php?title=Motorola_Defy). Everything will be Stock normal. Read everything in the wiki before you flash anything, esp read the "How to get back to Normal in case things go awry" part you will save yourself the High BP!
thanks all for your support.
i have installed the orginal manufactuer android froyo
and flashed it later with cynogenmod 7.1 for defy. The latest stable one that was released yesterday
One more question:
Should I unroot this cynogenmod .. so that I don't mess something.
congratulations
you sorta came from behind and am sorta left behind
question: does the 7.1 have any wifi issues? working properly?
tell me so i can make the jump too
thanks bro
sorry for the late reply..
no it does not have any issues.. at least i could'nt find any.
wifi was working like a charm. used it for around 2 hours ..
Couple of questions..
1) i don't lke the menus flying into the screen. How can i change this animation to the normal fade animation that came with original os.
2)should i unroot my cynogenmod should that i don't cripple it while playing with settings or someother way.
Do not unroot CM7. Make site you make a backup in recovery, that way if you mess something up you can just restore it. As for animations, go to settings> cyanogen settings> display, you should be able to change the animations. If not try spare parts app.
Swyped from my MIUI Defy
i have defy plus.....i havnt rooted it ...its working on original 2.3.6
my phone is starting but power button not working.....when i put it on charing lock screen comes to life but touch not working..
sometimes it remains on moto logo
please help

[TELUS T959D Fascinate]-Running ONECOSMIC'S ICS

Hello.
This is where you can look at the tutorial and get the files to install if you feel like jumping into it ...
ICS Step by step and files
Note: if you do flash this and it hangs at the boot screen, pull the battery and flash it again and it should work. Some have had to do it 3 times.
I take no credit for this ROM and full props go to the developers of the above post and all those working to make this happen.
First the look and feel of ICS is nothing short of superb. The speed as of now is similar to all the other ROMS I have tried with a little chop here and there but nothing major.
Yes lots of little issues and items that do not work like the camera and GPS but not a huge deal for me so I am willing to stick to it.
Battery so far is decent. 13 hours and 43 min. on the first charge to calibrate and sitting at 24% still. This included allot of playing with the phone and reboots to test jigs
As for the issues that are somewhat bothersome, they include the following.
1. No home or search button. I know same as usual when installing an i9000 ROM but the key mappings from the GB ROMS does not work.
2. BLN (issue all around) will remain lit until you wake the phone to get the notification.
3. They had to do some funky stuff to get 3G to work so it lags to start. Not a huge deal cause it does start and remain working.
I will be continuing to use this ROM and hopefully everything will be working soon (these guys are flying. Also I have been told that the folks over at Glitch are already working on the kernels for the ICS port so that is promising as well.
If there are any other out there running this on our phone chime in with your thoughts or fixes if you have any.
Thanx
Bucky
Thanks for starting this thread. Can't wait to hear about your progress.
Alpha 7
Hey here is the update ...
Installed the Alpha 7 update today and I have to say this rom is fantastic.
1. Camera is fixed and works like a charm.
2. GPS locked in seconds and accurate indoors!! Big improvment over all other roms I have used.
3. HW Acceleration is fixed and working from what I can tell
4. You Tube is fixed and can watch video
Still on the not working list
1. Can not plug the phone in while off as it just restarts. this is a work in progress and known issue
2. Can not record video
3. Will not read a SIM card for contacts and so on (thank god for Google sync)
4. Still no home or search buttons (I think I may need to work on that on myself unless a kernel is released)
SO my review so far ...
No real issues with the general use of the phone. Text, phone, email and web are solid, I have installed apps from the market with no issues and not one FC yet. Battery life is good and nothing is taking over. I have been able to use the phone all day and still have lots left over before going to bed and plugging in. I have not been through a full battery as of yet but that is what I am working on now.
Memory - Last I looked I had 174MB of memory remaining which is the highest I have seen.
ICS is really smooth and fast while moving around. I am going to continue to play with it and report back here for everyone.
I don't use a whole lot of apps so there won't be much regarding those.
Thanx for stopping by and I will post pics when I can.

Thanks for the update. From your review, it sounds like an awesome rom. Can't wait to try it but need them to fix the video recording first. Although I might just cave and try it out just to see what the fuss is all about
Can always restore my current setup... lol.
Update ...
been getting the SOD today and not sure why, I mentioned above that the HW acceleration was working, I misunderstood and it is not fully working yet.
I found that the system partition is very small. There was an update which required copying libs and there was not enough space left to do this (2MB). Not too sure if this is due to coming from MIUI or just a ROM issue.
Alpha 8 was released but had quite a few issues so not flashing that one.
Daily use has been great so far (except for the SOD) with no reception or data issues.
I am still working on the home and search buttons but I think that will get fixed with a kernel update. I tried the keymap file but these buttons do not even register in recovery so I get nothing in the ROM either.
More to come ...
Haven't tried this (likely won't as I need the phone for work) but buck have you tried the manual key fix - some directions in our thread on putting on Darkys 10.3.

Hey buck , was doing some searching in teamhacksung's thread about their ICS port, and someone suggested to change the following and then the key mapping for our phones will work properly. Not sure if the file system is the same for both, but definitely a bit of info if it isn't!
All you have to do is change this part on**arch/arm/mach-s5pv210/mach-aries.c*

Hey, have a telus fascinate too. Know how to flash and all that fun stuff. Just don't fully follow where you make the changes for key mapping...if you could just guide me in the right direction, I can figure the rest out...
changes in the kernel zip? the beta zip? after flashing? something completely different?
thanks a lot!
There are no changes to be made with this ROM, they are built in. Just flash and all good.
I will post update tonight after work.

There are allot of BT related posts in the QA. I personally do not use any BT but I do have a headset that I will try when I get home.
Seems to be a battery drain issue too as my phone is now dead but I have not calibrated so we will see after I do that.

AT LEAST YOU GUYS HAVE IT RUNNING!!
I am having a hell of a time trying to get it to work. I have tried so many different ways to get it up and running but no luck.
I've tried installing it from MIUI 3 times but all I get when trying to boot into ICS for the first time is a Black Screen after the FuguMod boot screen.
The funny thing is that the 4 soft buttons at the bottom light up still.
So I then decided to try the JVT way:
-Flashed JVT DARKYROM (ODIN)
-Lagfix OFF
-FULL WIPEs (factory reset, cache, dalvik)
-FLASHED CM7.1 STABLE
-FULL WIPEs (factory reset, cache, dalvik)
-Flash ICS BETA1
-Flash kernel
-FOR THE SECOND TIME:
-Flash ICS BETA1 AGAIN
-Flash kernel AGAIN
Same issue, black screen after the FuguMod boot screen, buttons still light up.
So i tried a couple more times in a few different ways based off what I have already tried, but this time, before booting into ICS for the first time, I installed the 'Superuser-3.0.6-efgh-signed.zip' package.
Same issue. I'm not having any luck here.

OK so here is what I did ...
Started from MIUI 1.11.18
1. Do a nandroid backup
2. download all the files to the SD card. This includes the ROM, Kernel and super user fix
Links:
Kernel:http://ice-cream-sandwich-sgs.googlecode.com/files/FuguModICS_GT-I9000_update.zip
ROM:http://ice-cream-sandwich-sgs.googlecode.com/files/ICS_4.0.1_r1-Beta1-i9000.zip
Super User:http://ice-cream-sandwich-sgs.googlecode.com/files/Superuser-3.0.6-efgh-signed.zip
3. Boot to recovery and do factory reset, wipe cache and davlik cache
4. Install the Kernel first and reboot now
5. Boot into recovery factory reset and wipe cache and Davlik and Install the ROM then reboot now
6 Boot back to recovery and install the Kernel again with out the wipe
7. If after reboot you do not have root then boot to recovery and flash super user fix
8. reboot and it should be working at least it was for me
It seems to me that you are missing the first flash of the kernel before the ROM. It sets up the file system from what I gather
Note: If needed flash the kernel and rom then kernel again with all the wipes as mentioned above.
I know there are allot of folks having issues getting it to run. Not too sure if it was the way I installed MIUI that might have made the difference.
My battery is charging now so I can calibrate it and see how it goes after that (it drained pretty quick today) lol.
I hope you can get it going cause it truly is awesome
Still not working:
Can not charge with the phone off
Google TTS stops working
Phone will not vibrate for SMS or email when in silent mode
BLN stays on for notifications until the phone is taken out of sleep (can be turned off)
Compass is why off (have not attempted to calibrate yet though)
11 MB left in the system partition (not much but I do not think there will be many changes there)
Video play back is choppy and some will not play
Bucky
regarding the black screen:
- had that too... I let it sit on the black screen for 2-3 minutes and then it went to the boot screen animation (a multi-coloured )...that for a few minutes...then finally booted.
How i got it working:
a) Started on MIUI...booted into clockwork
b) Backup
c) Wipe data / factory reset and cache and dalvik cache
d) Install rom and then kernel
e) Restart
f) Install rom and then kernel
g) Restart and wait very patiently for a little while
h) Once it all works, can reboot into clockwork and install superuser
Good luck! I really think the rom is nearly stable enough for daily use...
-------
Also have the no vibrate on silent... haven't tried the other stuff yet.
Oh and TTS hasn't crashed on this version yet for me...
Astrid glitches a little to a lot.
Changing from google tts to picco tts solves the problem there. As for the other stuff it is all reported as known.
I am using as a daily on my phone and no issues with general use. Still testing battery and that seems to be a bit of an issue with regard to Android OS as usual

Regarding flashing Glitch.v14-pre5 bootloop fix

Hi all
since i cannot post in Developer's apropriate forum i share with you here..
I have tried all ICS rom there is (not that many yet..) with Glitch v14 pr5 kernel, and they ALL give me bootloops... if not right away then after some period of time, and there is NO way to enter CWM
So i reflashed many many times in odin with different stock and other roms, but always with same result bootloops or a glitch screen logo that dont go any further.
Only if i go in recovery and format ALL options avalible and do a wipe data/factory reset afterwards + run the reset nstools zip avalible (off course only if you have been installing the glitch kernel )
Only then i get a error free install + i can boot in CWM and reboot whitout getting these errors......
Then im able to install > [ROM]SGS ICS 4.0.3 Doctor's ROM [01-12-2012]
and running on day 2 whit out any errors now..
Using nstools to oc and undervolt, is working fine selecting one of the 2 new goveneurs interactiveX or smartassv2 and DIDDLE deep sleep working perfect, BUT nstools wont tel you i always shows 0 in idle time (its nstolls fault) but voltage control EXTREME shows the right numbers
EDIT: Forgot to say that i pulled the externel sd card before going into CWM ! and do NOT deactivate nctools in app maneger !
Hope its ok posting this here ? plz delete or move else admins

[Q] ICS Screen Autorotate not working

The Official OTA 4.0.3 ICS update broke auto rotation. The rest of the thing is running smooth as butter, but no auto rotation and the switch isn't doing anything.
Anyone know of a fix to this? I had this prob with the leak but after rooting and reinstall leak from scratch it cured itself. This one isn't doing that.
Is there an app to set the orientation of the screen manually that i can use in the interim??
------------------------------------------
400+ Views later, i think quite a few people have this issue and are trying to find a solution to this.
So far, thank you networkdawg for your app suggestion for manually rotating the screen, however that is a paid for app with a few too many options for my need. I'm currently using Mantano Reader Free to rotate my screen.
https://play.google.com/store/apps/details?id=nl.fameit.rotate
------------------------------------------
Before i accidentally upgraded to the ICS leak, i had my old HC bootloader and was running Lightspeed flawlessly.
Does anyone know of a way to downgrade the bootloader back to HC so i can run a custom bootloader?
OR
a custom bootloader for ICS?
------------------------------------------
Ok so in the end i used jazzyjames' tutorial and blasted HC + HC Bootloader back onto my tab (accelerometer now working once more), rooted, ran Acer Recovery Installer and loaded Light Speed ICS once more.
Everything is working swimmingly. No issues and i got ICS running like a champ.
When the hardworking devs in the dev section have streamlined the ICS bootloader unlocker and installing of a custom recovery a little further, i may try the ICS bootloader once more. But for now, to just have a functional tab, im sticking with the old stuff a little longer.
Thanks Civato, Blackthund3r and jazzyjames for their excellent tools and tutorials. I could not have done it without their help.
------------------------------------------
Update May 08 2012
Did something new, reverted back to stock 3.2.1 (the Gen 2 that was used in Jazzy's revert tutorial), did an OTA upgrade to ICS Official. On first run everything worked.
The minute i rebooted, the accelerometer stopped working.
Followed Civato's tutorial down to the letter, got the custom ICS bootloader working with recovery. Ran like a charm.
Installed a custom ROM (Lightspeed), accelerometer was still not working.
MY TAKEAWAY ---- The accelerometer issues is not a problem with ICS itself, but related to the new chipset firmware and bootloader included with the ICS update. I could be wrong here.
Anyone have any other insights into this?
Back to HC bootloader once more (accelerometer working again) no dice with ICS bootloader :S
I'm not aware of any apps that will switch orientations, only lock it.
Have you tried switching the lock to off then rebooting to see if that resets it?
I have noticed the orientation check isn't as sensitive as it used to be so sometimes I have to wait a few extra seconds or orient the tablet a little more [than usual] to get it to switch over. But it does work.
I have the rotation problem also. As a workaround, I installed this and it works great, although manually.
https://play.google.com/store/apps/details?id=nl.fameit.rotate
veer01_42 I'd be interested in your review of that app if you use it and/or pay for it.
I have the same issue. I have a couple apps that are orientation locked and I can use them to rotate but it's very annoying. Hope this gets fixed soon
anyone try a factory reset to see if that fixed it
A factory reset fixed it for me
Sent from my PC36100 using XDA
Been factory resetting this thing all night, no beans at all.
With the 4.0.3 leak, after one reset it worked for me, but i never got it to repeat again. So don't go factory resetting your tab in a hurry if you know whats good for you, especially if your rotation is working.
Good app, lots of options, but for what i want, this app is too much and it puts an icon next to the clock for quick access, but you cant preset the orientations there. There are only three, locked, auto and whatever you have it in now.
To get to the other options, tap the notification and it brings up a menu with all the other orientations (over 10 of them) its too much for me. But its an extremely powerful app.
Not worth the money as a workaround to a stupid accelerometer.
Encountered the same issue. I was in Portrait mode, playing Draw Something, and suddenly it just rebooted and went into Landscape mode. After a factory reset, it is not fixed. Not sure where to go, but this is highly disappointing for a tablet I paid close to $500 for...
Try wipe cache, it works for me. All said methods in the forum doesn't work for my tablet though.

What cache?
Do you mean Pwr Button + Volume Up while toggling screen lock switch?
Or is it something else?
On some a500 that were rooted and accepted the ics ota, a few things got broken during the upgrade. Flash a stock rooted ice rom, but before you do go into recovery and and select backup an restore,click on toggle backup of internal storage. Then you should see enabled on the screen. Then do full reset in mounts and storage plus your normal wipe. This will fully format everything on your tab but sd . When you reflash the new ics rom everything should work fine.

This is in the ICS V3 custom bootloader/recovery right?
variations on problem for different versions
More pieces to the puzzle.
I just downloaded and installed Acer_AV041_A500_1.041.00_WW_CUS1 (very close to stock OTA, but rooted) from XDA and applied it over the stock OTA I had received from Acer directly, Acer_AV041_A500_RV05RC01_PA_CUS1.
Under Acer_AV041_A500_1.041.00_WW_CUS1 screen rotation (and the error 26's) would not clear. I could not get the rotation to work at all, even with multiple reboots, and hard (pinhole) resets.
I restored to Acer_AV041_A500_RV05RC01_PA_CUS1 and rotation is back to it's unstable self, but at least a pinhole reset will clear it.

Auto-rotation not working in ICS, possible driver issue and resolution path?

As a noob, I could not post this in the thread where it applied. I hope someone sees it and passes it along.
Problem: the tab does not automatically rotate the screen image when you rotate the orientation of the device. The lock switch is "unlocked". The problem arose after the ICS update was applied.
I found this link in another device forum that seems to be dealing with the same issue.
http://forum.xda-developers.com/showthread.php?t=1592170#
Basically, he replaced the accelerometor sensor driver files I think.
Hopefully one of the developers here will see this and can hookup with the other author to see what is really going on finally.
Until then, we need to keep a safety pin handy to hard reset the A500 when it goes insane.

Clean boot your tab. This will force the OS to install itself again.
Note: Clean boot will erase all the data/information which is saved on your tablet. Recommend you to back up the data before performing a clean boot.
1. Shutdown the tablet
2. Press and hold volume up key (the key next to rotation lock) until you finish step 4.
3. Press power button for 3 seconds until you feel device vibrates then release power button.
4. Once you feel device vibrates, very quick to switch on/off "rotation key" many times (this activity has to be done very fast, otherwise it will not succeed). To ensure you succeed, switch on/off rotation key when Acer logo appears on screen.
5. Wait for a while (you will see Erase Userdata and Erase Cache on top-left corner on screen), device will reboot and start from OOBE screen.
See if that fixes it.
Didn't work for me had to factory reset tab to get accelometer working again. This is the second time.

Erasing as suggested did not help. Only thing found to help so far has been the pinhole hard reset. And, even that did not work once I flashed to "Acer_AV041_A500_1.041.00_WW_CUS1" version. I reverted back to what Acer had pushed to me, and it is working as well as before, meaning, it works as long as you have a pin ready to stick in it.
I have something to add to this thread. The auto-rotation issue started for me after switching to the V3 ICS bootloader.
I kind of found a workaround for it. (If you can call it that)
If I start or reboot my tablet in portrait mode. Auto-rotate works
If I start or reboot my tablet in landscape mode. Auto-rotate does not work.
This happens each and every time. It happens on Civato's new FlexReaper ROM & with Smaury's Lightspeed ROM.
Moscow? Thoughts?
Apparently how I finally solved this problem is by flashing the custom ICS bootloader V4 (read: V4 ONLY). Had tried V3, V6 and it doesn't work.
Had tried both custom ROM and stock ROM the problem will still persists with the said bootloader. But once on V4, it just works like a charm.
I have the same issue with the ratation.

How do I flash custom ICS bootloader V4? Where is it available? And can it be flashed on top of a stock Acer ICS ROM?
FWIW, although I LOVE having Android tablets, issues like this drive me away from Android phones as I can't deal with this sort of bugginess on my daily use phone.
Ahhh, my other half has just phoned me about this, seems it started doing it after she dropped the tablet, I put the ICS update on it the other week, be nice if its a simple fix instead of a me having to take it to bits and repairs it fix..
Although I could give her my Xoom and then use that as an excuse to get myself something new
