[Q] Problems after official ICS update- need help on rooting and else - Acer Iconia A500

Hi everybody, first of all sorry for my english.
I bought an A500 on ebay a couple of weeks ago, OS was 3.2 factory, I was thinking about trying to gain root permissions and maybe install a custom rom but tablet seems to work ok and I decided to wait for official ICS release, which arrived yesterday.
After the upgrade I noticed, as others did, strange behavior of wifi connection (strong to leak) and I cannot add any widget on home screen (keeping tapped shows only choices for changing theme).
At this point I guess it would be wise to try and install a custom rom, but I’m not confident and I really need help from the start.
I understood I need root permissions, but to gain them I have to downgrade.
Can anybody please tell me what to do, using dumb-proof terms ?
Many many thanks in advance.

update: i tried to downgrade to android 3, i think i bricked it ...
after the update i get a red error "Boot verified failed" .....

Probably wont help much now that you've bricked it, but to add a widget you need to be in the app menu and switch to the widget tab. And you should try looking at the wifi settings for default action when sleeping. For some reason, mine changed to always disconnect from wifi after turning off.

many thanks for your answer

[Q] cant update my a500 from 3.1

Hi. i get my acer today and when i launched device new update came up (350mb) so i started downloading it. when it downloaded about 60-70 % of all it disappeared. i was trying few times, i even change ip to static and it doesnt help, can you give me any advice ?
I read somewhere in here or one of other Acer Forums for the update or one of the updates to work is to be sure and not let the unit go to sleep. In other words, tap or ensure the screen stays up and not go to sleep mode during the downloading of the update. I am sure there are others that will jump in to correct to add to this. Hope this helps....
that might be true i will try to keep it active and let you know, thanks
nope it doesnt help :-( im getting tired of this, do you guys have any other idea?
i think updates have time limit, any idea how to turn them off ? becouse i hve only 512kb/s and 350mb is downloading about one and half hour
Funny question, but why stay stock? I would root it, then install acer recovery and flash to 3.2.1 stock rooted (if stability is what your worried about) or flash to flexstriker or something else

Accelerometer not working

Hi all, I was wondering if you could help with an annoying issue I'm having.
I made a big mistake by updating to an ICS Rom, it worked fine apart from the accelerometer which stopped 100%. I did a backup, but system crashed and that's the end of that backup
1: I've since downgraded to Honey Comb Acer_A500_7.14.14_COM_GEN1, but Accelerometer still won't work, I don't know why, is there some fix or file to replace or anything like that.
2: Second question, because I updated to ICS the boot loader got updated also, is there a way to revert the boot loader back to the original so the end product would be a 100% original
This is a 16GB UK version of the A500, so any help would really be grateful. Even if I can get both the boot loader and OS to original I can then send it off to Acer for repair.
Kindest Regards to all

Man, I don't have an Acer iconia, but I have a Samsung galaxy player 5.0 and I just experienced the same issue after trying an ICS ROM.
When I searched for a way to solve my problem, I've seen many many users (increasingly, indeed) with the same kind of problem. It's hard to think that so many users are having accelerometer hardware fail. I believe it's not physical problem, mostly because this kind of issue happens after ppl try modding their phones/tabs or changing roms. I've seen some users talking about removing a sensorfile yamaha.cfg and trying to reboot the device. That didn't solve my problem, or executing:
"sensorcalibutil_yamaha"
It is under /system/bin/, you can see that with root explore.
Unfortunately, didn't work for me. Hope it works for you.
Best regards.
Thanks for your reply, I found a way of down grading the bootloader and OS to 3.0.2 which fixed it, then updated the odds to the latest and back working 100%.
Hello, same issue for me, accelerometer doesn't work anymore! I had yesterday the official ICS fota. Is there a patch somewhere for this problem?
after official Acer ICS update - Accelerometer quit?
My A500 pad just quit doing auto-rotate just about 30 mins after I applied the "official" ICS update to my device. I haven't done anything different, I did lock the pad into portrait to read some stuff, but unlocked it (manual switch) and it was fine then all of a sudden - it stopped rotating between portrait and landscape. The switch now has no effect on it. Of course there's not a setting to change the rotation either. Argh? I was so excited to get ICS - not this goofs on me? I see quite a lot of posts about people who experience this from hacking around on their tablet or phone - I haven't hacked on this one at all - its the "official" stuff... Reset didn't help.

I need to do the exact same thing. Could you please let me know what you did to start all over and get all the OTAs?
Thanks!
One could conjecture that if the accelerometer is stuffed, so would the orientation detection be.
Cause and effect?

Same here but a reboot cured it.
anyone find a fix for this ? im on the official with no root ics update and mine has also stopped auto rotating.
What did you use to do the downgrade back to 3.0.2?

The only solution I found so far is keepin rebooting, eventually at some point accelerometer starts to work.

If any off you had a leak and altered boot loader prior to install, it may have caused that. You should have had a 2 step optimizing process in the update, when I tested it on a leaked/flashed back version the bootloader was wrogn and that issue resulted. The stock had no issue and went through the full hardware optimizing process.
Also you shoudl have applied the market place update first, it has a pre fix to prepare it for patching.
Hey guys, i also have the same issue with accelerometer. I downgraded the a500 to Honeycomb and it fixed now.
I followed this guide: http://forum.xda-developers.com/showthread.php?t=1516012

the guides to rollback posted above can be used on an official pad , with no hack or root stuffs ?
No, it rolls you back to rooted 3.2.1. with stock bootloader. Once ur back, you can load your official 3.2 rom on an SD, use Pwr + Volume down to update to it. Then OTA to ICS.
Just saw a guy posted a system of methods to completely wipe all the system files (not just most) and clean install ICS which supposedly fixes the accelerometer problem.
Accelerometer / ICS
I sent my tab back to Acer for repair, they say they replaced the "motherboard" and it did work fine on stock ICS as returned for a while. Periodically it would stick in orientation and not auto-rotate, but a power cycle with a few minutes in between seemed to always bring it back ok. NOW - nothing I do brings it back - its working the very same way it was when it originally experienced this issue. I don't want to send this slab back to Acer every couple of months and deal with setting it back up when they ship it to me a week or so later. This is rediculous or am I just being picky?
Anyhow - How bout a reference or link for the info on downgrading, wiping ICS and re-installing from scratch as mentioned above? That would be helpful if I knew where to look.
UPDATE: This morning, based on another post about finding errors in the bootlog, I downloaded the bootlog capture app, ran it, and poof - the auto-rotate function came back to life - like magic. I'm sure it was NOT the app, but rather the fact that I had powered down the unit and let it sit all night long without touching it or powering it on/off, etc. so at least for now, I won't be sending it back to Acer for Warranty repair (AGAIN). BUT I might be listing it rather quickly on ebay and shopping for another tab that doesn't have this issue....
I have had this issue and normally a power cycle fixes it. I did have one time where it did not but I found an article that said to do a hard reset. You do this with a paper clip pushed into the very small hole. I did not lose any data.

help please! my tab's wifi wont stast! [error]

hello xdadev,
i really need your help. I am a newbie in android world [just purchased my first android device] last month [samsung galaxy tab p6800]. since then, i was really excited to explore android world and its features where I was led to this site.
now, heres my problem: just this afternoon, at first, i used my wifi to access a shopping mall internet connection. but minutes after turning my wifi off, when i turned it on again to connect to another network, i was surprised that it wont start and when i open the settings menu, under it says error. im really worried.
had my unit restored to factory settings but still no changes. Rooted my galaxy tab but today, i unrooted it thinking that the rooting caused the trouble.
im also hoping to update my tab to ICS but with this problem, im really stuck! i dont know how to access my apps in the appstore.
is this a firmware error or a hardware problem? please help me. my tab helps me a lot.
thanks in advance. im willing to add some details if you could help me.:crying:
try to go back to the mall where it 1st connected, if it still doesn't connect, then use your warranty and ask for replacement.
7.7 is notorious for being a bit choosy when it comes to wifi, sometimes, it just stuck with "obtaining IP address" then will revert back to scanning.
I also encountered your error before, but I just simply turn the wifi on and off again
before going back to your retailer, try to totally deplete the battery first (it's like removing the battery) then charge your unit and try to connect again
good luck
the last thing i could remember was busybox got updated but failed to install. is there any possibility that the failure caused the problem?
nope

Ah, sorry, busybox could, and may very likely be the culprit! An older version did just that to my (I have the 6810), and a number of others, tabs.
This was for Stericson's version 8.0 and here was his reply to my email:
Sadly you fell prey to a bug that was in Version 8.0 of my installer. I fixed it in 8.1, but it seems many still got the bugged version.
To fix the issue, you need to reflash your current rom. You do not need to wipe or clear any data.
You can also look in this thread: http://forum.xda-developers.com/showthread.php?t=1691410&page=2
It has an update method that should fix your issues.
Again, I apologize for this error
Please let me know if you need anything else from me.
I did just that and reflashed my rom using Odin and then re-rooted. I haven't, since, re-installed Stericson's busybox although later versions supposedly fixed the problem. I see there has just been another update in the Play store.
Damn I got the same error today, also after a lot of updates came trough.
Still working on fixing it. Will restore backup first after full wipe..
EDIT : Ok just went to recovery via power+volume up , factory reset, a nandroid restore and wifi working again.
Phew.
Ah! Got my tab working again. Thanks guys for the link and comments. The (update. Zip), did fix the issue. Busybox related bug. Starting to re download my apps again since I got my tab data wiped. :-(

!!!Stop SAMSUNG GALAXY S3 FREEZING Problems!!!

Well, here is my story...
My cell phone is a Samsung Galaxy S3 mod. GT-I9300. Locked for Digitel (Venezuela mobile carrier). Android Stock Rom version: 4.1.2.
Preamble:
I bought this cellular a year ago, and it worked flawlessly almost for 12 months straight. I haven't experienced any single freezing or rebooting problem. I downloaded KIES and the program detected that a new version of Android was available for downloading for my phone. Bump! Error. I should have backed up my EFS first before doing the upgrading. BACKUP YOURS, IMPORTANT!)
NOTE: Backup your personal data as well since any ROM installation will remove for sure your personal data and info.
After upgrading and a few days later, my cellphone started to act somewhat funny. I started to got some freezing. To be specifically, my phone started to freeze, the screen just froze and nothing happened when I touched the screen, pressed any button. The only thing worked was to restart the cell (by pressing and holding the POWER button or by removing the batteries). Anyway, the freaking freezing problems continue occurring.
By the way, the warranty expired just a few days ago...
Since I couldn't do anything to stop the freezing problems, I decided to root the cell and install a new version of Android not official for Samsung and test its performance. But before that, I factory reset my cellphone, but it didn't work at all.
I tested several Android version I could find on internet: cm-11-20140....-i9300.zip, specifically, the SNAPSHOT, STABLE, NIGHTLY version. None of that worked, I also tested the cm-10-20... without luck. In fact, the freezing problems with those versions got worse and worse.
Taking the above in consideration, I decided to re-install the stock rom version (ver. 4.1.0) the one that was shipped with my phone when I bought it. You can find these version for any carrier in the world at: sammobile
I flashed and I used it for almost a day or so. During that period of time, I could feel that the freezing issues were gone, not even a freezing event. But unfortunately, I couldn't connect to any Mobile Network!!, so I had just bricked my cell phone !!! I took it to the cell carrier company (DIGITEL) and they could not do anything since my warranty already expired. WTF ! I was alone with my own problem now to sort it out.
SOLUTION !!
By no means I mean this is a cure but I have just stopped getting the hellish freezing and rebooting problems, and I just wanna share my experience with you so maybe I could help you to get rid of this annoying issues for the time being.
Picking up where I was left off, all I had was my bricked phone and a working ROM: ver. 4.1.2, So I decided to to reinstall this version back on my phone and see if it connected to the mobile carrier.
I reinstalled it and of course, after erasing cache partitions and making a factory reset. The procedures to install any ROM on your cellphone you can find it on internet (for instance, youtube may help a lot).
After I installed the version 4.1.2. my cellphone could connect to the mobile carrier once again... phewww!! But the freezing problems continued to appear in the fuc# phone. Well, now the only option I had to test thoroughly my cell was to install any application one after another but testing if the application was the culprit for the freezing issue.
But right after installing the stock Rom, I got a error message when my phone run to the first screen (Home Screen): TOUCHWIZ stopped responding... it lit my LIGHT BULB! I searched the web for the TOUCHWIZ and found out reports regarding many problems with Touchwiz.
Holy craps! The TOUCHWIZ is a BUGGY APPLICATION that comes with the STOCK ROM developed by SAMSUNG.
My friends there is no way to UNINSTALL that application but to use another LAUNCHER. I fired up and decided to download KIT KAT Launcher. Well, I downloaded the launcher and when you first run this application a windows pops up so you can decide what launcher the cellphone may use and the time to use it. I select ALWAYS I press the HOME button, the launcher to use is KIT KAT.
In addition to that I disable various stuffs, follows (you have to go through the setting app):
Disable Touch wiz (delete CACHE, and FORCE STOP)
Disable GPS
Disable Multi Windows
Disable Swipe Lock ( I found my cellphone freezes a lot while this is on)
I don't use a lot of widgets... but only one: The Clock and Alarm widget.
So far (it has passed 5 days straight without freezing). My phone froze on me while I was downloading something (maybe the phone was updating an app) and at the same time I was texting someone. I am suspicious that there is something to do with the downloading system too and the phone that could trigger a freeze.
Anyway, if you have experienced the freezing issue on your Galaxy S3 just like me, then try what I just outlined and give it a test. But do not download a bunch of program at the same time, just pick one by one, and allow some time to test your application and check if your phone is stable before continue with the next app to download and so forth. I have downloaded so far: whatsapp, BBM, sudoku and other games.
Hope you can get rid of the freezing problems just the way I did, any question feel free to ask.
I will continue posting any advance with my phone.
FROYCARD
PS: excuse my standard English.
Flashing a custom rom would help with the freezing issues too!
Try temasek's 4.4 rom its a lot more smooth than ur stock ull feel u have a new phone
You also lost ur carrier signal because ur efs partition was read only or something so backup ur efs before flashing the rom

Nope,, it didn't work with my cellphone. I already tested it. As a matter of fact, I can name you all the ROM I flashed to my cellphone:
cm-11-20131115-UNOFFICIAL-i9300-V2
cm-11-20140104-SNAPSHOT-M2-i9300
cm-11-20140117-UNOFFICIAL-temasek-i9300-V36
cm-11-20140125-NIGHTLY-i9300
cm-10.2.0-i9300
None of the above rom I used stopped the freezing issue, that's why I needed to return to stock rom, and since then I am using it without experiencing any laggy or freezing.
Thanks anyway. :good:
Isnt it possible to create a rom with all of Samsungs bloat ripped off (TouchWiz included) and replaced with stock apps?
The problem is that non stock kernel roms use up a lot more battery than the stock one...
what?
i havent got this
Dude, you seem like a total beginner at this. You might want to start by trying a proper wipe, install a rom like Temasek and install a kernel like Boeffla.
Touchwiz is not the problem for your freezing. Get a custom kernel on there and try undervolting to lower the temp your phone. It may be too hot and may lock up.
You don't have to stick to roms available from your carrier either. You might just want to try any recent 4.3 rom from Sammy.

Yeah,,, you may be right I am a newbie... but since I stopped using TOUCHWIZ, I have experienced fewer a fewer lock-ups. I dunno what it is happening with my phone, but that is a fact. I am using KITKAT launcher.
The current stock ROM I am using is: 4.1.2 .... (I9300UBEMH2)
I am not familiar with undervolting to lower my phone's temp... maybe you can guide me about using it, or I could search the web for it.
UPDATE: I installed TWITTER Apps yesterday and each time I used it, it froze my phone for 12 min approx. Any suggestion?

Why should I? Are you a moderator of this forum?
Well I just want to update my post.
Yesterday I just wanted to continue figuring this freezing problem out. Since I published my experiences about freezing until yesterday the problem appears to have reduced significantly. I was using stock ROM ver. 4.1.2 flashed with KIES.
But I wanted to continue testing other ROM's. I tried to install a ROM named SAMMY'S ROM developed by guy named JustArchi (that I found in this forum). However I could not install it on my phone (SGS3 - GT-I9300) since it gave me some errors when I tried to install: ERROR STATUS 7
A margin note: This techie or nerdie called JustArchi gave me the boot from his thread for trying to seek help on this error.. so I trashed this SAMMY'S ROM and move on with another solution.
Whatever, I downloaded another official stock Rom ver. 4.3, released by SAMSUNG, intended for IRELAND - I am not from Ireland, but Venezuela (I founded it at SAMMOBILE under the top 10 latest firmware just released). By using ODIN, I flashed my phone, and to tell the truth, my phone feels differently. I haven't experimented any sluggish or lagging, not even a freezing so far (knocking on wood).
For precaution, I am installing one app at the time, and giving it time to see if everything is stable.
Conclusion: to any guys who is getting the annoying freezing, I think you must stick with it until your mobile carrier makes ROM ver. 4.3 available. Otherwise, if you are like me, wanting to work things out for yourself, download any ROM (ver. 4.3 compatible with your phone model) and test it on your phone. Before doing that, you just have to search the Internet for directions to do so, I am not responsible for what you do with your phone. I'll keep updating if another problem arises.
Note: since I am getting some rude comments from senior members who think they are too techie to read newbie's comments, queries, etc. I am not interested in their replies since they are not helping at all, thus I just ignore your lame comments from now on. Just scram.
Dude, you're really not helping anybody here with your information here. I don't know what you think you're sharing. The error 7 pertains to recover error which can be eliminated by installing an alternate recovery version.
I don't care if you're a newbie or not but you are spreading false info.
I'll scram now.

Help needed, Touchscreen is not working for Thinkpad 1839XF1

Hi guys!
My brother purchased a Lenovo ThinkPad 1839XF1 for his son, which is running CyanogenMod, and was converted to Android 4.1.2, but the touchscreen does not work. I´ve tried to change it with the physical button, which actually displays on the screen that the touchscreen has been activated, but it actually does not work.
I would like to know if there is any stock rom that can resolve this problem, or if there is another way to set it up. I already reviewed the setting, and there is no other way to enable/disable the touchscreen. I also forgot to mention that the Camera does not work neither, and an error is displayed when trying to use it.
I was thinking about the chance to use the update on Lenovo to try to change it, or if there is any additional steps to try to recover it, as I´m not able to find anywhere the stock ROM.
Thanks in advanced.
