[Q] A500 - "Android logo" loop

hello everyone ,
my Iconia A500 , just broke down or i don't know exactly what's wrong with it ,
it's rooted stock -ICS-4.0.3 , 6 months ago
and the last thing happened in the past 3-4 days :
1- "Air Playit" was downloaded 2 days ago
2- reading news /Facebook/messenger , occasional games
3- opera browsing
that's it , no physical impacts , nothing abnormal else
now for no reasons , the tablet shut down ..
and stuck on "Android" logo ...and never past that for an hour , then it shut down
any help please with "preserving data"?

I would connect Micro USB cable to PC and device...
and see if PC recognizes device...then if you can see it in ADB or APX mode..
at least you can modify stuff with PC recognizing it..
Maybe take out External SDCARD and click it back in.
try to boot into recovery mode
mess with it when power cord is plugged into it and NOT plugged in
*** IF you are ever are able to enter into a RECOVERY mode, I'd wipe Cache + Dalvik (so it can refresh files and apps) (it doesn't erase anything, settings, apps, etc)
hope you have your CPUID #
Dought this is very helpful, APX mode saved me after my tablet was bricked for 2 months

anyway , how to get it now ?

help

things been done till now :
1- CPUID extraction
(1) From a PC using Blackthund3rs A500 manager
not readable
(2) From your device using Terminal Emulator App
not accessible
(3) From USBDeview must have previously used the Tab under HC with the PC you're using
only 11 digits were founds under the exact given criteria
(4) From a uid.txt in any Honeycomb-cwm backup in external_sd/clockworkmod/backup/"your_HC_backup" folder
not available
(5) From adb devices if you're running honeycomb
not available
(6) From cwm 1.7.2 via on screen display and a text file - great if you are on ICS already
not accessible
(7) From a working system in /sys/firmware/fuse/acer_cpuid
?!!?
** USB doesn't recognize the device , tried multiple ports , USB 2 , 2.1 and 3 (USB driver installed)
any more ideas ??

Well I wish that I could help in a way that would let you preserve your data. Hate saying it. It is probably lost. The 'save my data' prerequisite is probably why there are no answers to this point. I won't say that it is impossible, just highly unlikely. Sorry.
So if you get tired of waiting for an answer for that and just want to get your tab up and running I would humbly suggest that you consider these...
http://forum.xda-developers.com/showthread.php?t=1624645
Tons of great information and the support from the OP is legendary.
I think that you will end up at this page...
http://forum.xda-developers.com/showthread.php?t=1751978
This one is not an easy read or an easy process for those who lack Linux experience. But with a little patience you should be fine. Just be sure to read through the first few pages. There's a decent amount of information in that single thread, and not all of it is in the first post.
Once you get through those two threads you will, without a doubt, be able to continue with restoring your tablets software to something useable.
Good Luck.

I'm in the same boat. The same thing happened to me two days ago. Stock ICS + root are the only mods I've done.
I'm going to finish reading through to see if anything worked. :/
---------- Post added at 03:53 PM ---------- Previous post was at 03:42 PM ----------
In my case, I'm not so interested in preserving any data as I had already relocated everything important to GDrive and my external SD card.
First attempt, I tried booting into recovery which, I'm guessing, tried to grab an update.zip from the SD card that wasn't there. When nothing was found it proceeded to a green android boot screen and then quickly changed to a dead android with a hazard symbol on it. The boot bar below the logo crept slowly for several minutes and then stopped and hung for about an hour until I gave up.
Any quick ways to get me back to a stock blank rom?

ok , i think i'll let go for the data ... although it's VERY annoying -_- considering i did never lose any data since 1990 with dos / windows / symbian , i'm very disappointed with my first experience with Android and Acer ..
anyway here is my thoughts ,
1- first i tried All possible ways for extracting the CPUID in many forums .... except the "Ubentu" one ...which i'll give it a try soon after my surgery exam
2- another VERY annoying point honestly , it's the "inconsistency" ....
i mean , when i pressed the reset , it stopped showing me the "android-logo" , then after couple of resets , it started to show it AGAIN !!
then , doing hard reset (+vol + pwr + the or.lock) and confirmed erasing data and cache , the "android-logo" disappeared , and only ACER !!!
another , one normal reset , and it appeared again !!
ok ok ... let's forget this
i tried all 7 Stock ROMs ...
each SINGLE ROM , gave me at least 2-3 different responses !!
- the loading bar alone
- the robot with rotating thing , no loading bars
- the dead robot , no loading bar
- the robot with rotating crystal , with loading bar which get stuck at 25%-30%
- the dead robot , with loading bar which get stuck at around 20%
- Nothingness !! ( yes , it boot up from update.zip , then nothing happen)
*each trial , i gave it at least 20 min to progress up ... but with no use
anyway ,
3- i'll try again last time extracting CPUID , so i can install EUU ROMs .... but anyway ...
guys , does anyone know any relation between the S/N of the machine and the CPUID ?
just trying to think alittle bit differently , maybe , the S/N is 22 units long , so maybe there is a relation between them ?
4- if all failed , i think i'll have to wait till i get to dubai soon , because no service center in my country -_- !!
5- last resort , i'll use it as cutting table in my kitchen -_-
please guys ... help
IDEAS !!

i know you said the drivers are installed but I'm not sure they are....but try this
put your tab in manual apx mode and hook up to your pc - if theres an apx device listed then run afterOTA Lite version to get your cpuid that way...there is no relationship between the serial no and the cpuid...if nothing else works the only answer is Linux, as all the others have said

ok here what i have done ...
installed Ubuntu 12.10 ... done
installed all developer packages ...done
extracting the UID ... 0x3806148417f4317 ... done
double check ...the same result ...done
trying to convert to SBK ... FAIL
adding extra -as advised- "0" so the UID become ... 0x03806148417f4317 ...done
converting to SBK ... done
back to windows 7 ...done
trying to make "A 500 manger" or "A500 APX" detect the tablet ...fail
windows detection to APX .. done
retry "A500 manger or APX" ...fail
downgrading from "acer USB drive" 1.06 to 1.00 ....done
trying "A500 manger or APX" ...done
on "A500 APX" ... chose package 13 , put the SBK , APX detected , the tablet show "Acer" in green color with "Acer Iconia APX Mode" ... (finally something different)
"A500 APX" asks me if i saw the new "APX mode" ... yes
and then
it continued in all steps with success
till reaching " Exiting the bootloader..."
and it hangs for 30 min on that stage with no respond not what so ever !!! -_-
any ideas , guys ?? :fingers-crossed:

and
03806148417f4317
gives me the same SBK ...
how long time should the flashing tool take till it complete its job ?

ok ...
now that's where i reached ....
and nothing happens after that
i flashed this bundle :
Bundle 13: A500 ICS BL v7 / Thor Recovery 1.7
ICS Unlocked / Skrilax Bootloader v7 and Thor Touch Recovery 1.7 (Legacy version for those with issues with 1.7.3) for the A500
using the "APX a500 flash utility" ...
then i ended up with this screen (see the attached image)
and can't pass it at all
trying SD card update.zip ...failed
trying secondary kernel ...failed
trying hard reset ...failed
so ??

ok ... back on track .... UP and RUNNING

Hello! What did you do in the end? I have something not exactly the same, but a similar situation to yours. Your final solution could be my salvation too...... :crying:
Thanks in advance for any help.
Regards.

The tool he used flashes a custom recovery as well as the unlocked boot loader..for some reason the recover.img got corrupted...u must use the ones that come with the tool and use the tool to install it. Once u have the unlocked boot loader you're able to use a flash able zip to change it if u want.
So to answer yr question just reflash again. Choosing the bundle market option select bundle 17 its the latest version and seems most stable.
The window in the s/shot is fast boot menu, power volume up. Wiping cache helps if you are stuck on Acer boot logo

I9500 E: Failed To Mount /efs (invalid Argument) stuck Logo Samsung

Hi, I'm new to this subject and the truth of z3x 've started on the wrong foot .
buy my z3x to begin working with i9500 which turn on and I went out the legend only emergency calls, my problem was from the beginning , I have installed the drivers appear correctly on windows 7 x64, when I start the tool samsung 17 I bottom of the window says , cars found (OK ) and then tells me NOT FOUND BOX but starts correctly, however, if I open the shell on the i9500 model only reached reading card found and then a number XX -XX # # # # # # -XX or something like that does not matter because I assume is the activation of the box , well I press :
1 - I configured the phone in debug and everything.
I tried using the two - S7070 UART cable connect the phone to the box and I never EVER answer by S7070 UART uart cable or any other cable, 3300k clarify that I have not since I never came in my kit installation .
3 - Connect the original cable that came with my phone direct from my notebook and lo and behold, there I recognized the phone .
4 - unlock i tried to make no changes .
5 - try to restore the network, but no change either .
the phone had version 4.3 and up and did a downgrade to version 4.2.2 with the risks that could run . to the top after making flash 4.2.2 reboot when the phone was hung on the samsung logo , but I did a cache wipe and then a wipe and factory reset the phone when everything worked correctly.
6 - I connected the phone again and I 'll take my imei NULL to try to restore a previous efs that I had saved , well if it was not the version 4.2.2 or version 4.3, do not remember.
7 - with the phone connected by direct mini usb from my notebook always pressed write efs and instead of looking at my previously saved with root explorer folder, what I did now was to search the backup files that had generated me the same z3x not know why I did this, but I selected the one that had the oldest date before I modify anything, so thought I would take the information from my imei from there, but I flatly wrong.
when the phone restart was permanently a bootloop on the logo samsung and never could get him out of there, I intnté do wipe again and nothing happened, I can enter download leisurely mode and also in cw vol up + menu + power on the notebook I listed as usb modem phone or something, but as I fail to operate any single uart cable usb mini me works, read the info when I search the phone always says PHONE NOT FOUND, not let me take any further action.
8 - now when I do a wipe I get the legend on the screen that says ...
e: failed to mount / efs (invalid argument) and stuck at the samsung logo.
no more to do or how to correct my problems to revive this phone mia agony.
could someone give me a very detailed step tutorial that can make step. do not forget that many newly started on this topic and please talk with us tomense unclear terms and cordial to answer very clearly some things that are very easy to units for us but maybe very difficult time.
please help with my UART since my box is useless without this work or am I wrong?
thank you very much.
Updated:
w*w.clangsm.com/forum/index.php?showtopic=324565 (reference)
There is no way of putting on the version : - SEK - I9500XXUBMG1 20130702160308.zip - I9500XXUBMG1_I9500OXEBME1_I9500XXUBMG1_HOME.tar.md5
and will again lower the version 4.3 to 4.2.2 to see if the version mentioned so loaded up with this file ( Clar0 ) I9500UBUAMDK_I9500UWAAMDK_CTI.zip - I9500UBUAMDK_I9500UWAAMDK_I9500UBUAMDK_HOME.tar.md5
but it says the same thing in red UNSUPPORTED VERSION . when I try to charge you the version of the post : w*w.clangsm.com/forum/index.php?showtopic=324565
not to do now , someone hand me that ? if you do a wipe after the newly installed version of course I still dicendo E: Failed To Mount / efs (invalid Argument ) Locked In And Meet The Samsung Logo .
I forgot to clarify that after the error obviously odin and text on cell unsuppoerted version , if I disconnect and try to turn me obviously goes the legend on screen with a warning symbol (Firmware upgrade encountered an issue. Please select recovery mode in Kies & try again)

[Q] Overheating & Baterry Draining & Hang After about 1 minute

Sorry but i'm just a newbie here. Plz help me ... I'm having someproblem with my SS4 I9500 GSM only model. Just bought it a few days ago and yesterday after I root it with Kingroot everything still ok until I download the TWRP recovery on CHPlay. It show some kind of warning that could affect my SD but I ignore and have it done something to install the TWRP on my phone. After one time reboot my phone started to run real slow , super hot until hang itself and extremely battery draining ( about 25 - 30 % for one time boot till it hang and reboot ). I've tried to reinstall an Original Firmware but couldn't because I can't connect my phone with the PC everytime I tried to connect the cable my PC show the Code Err 23. Device not recognized. . I tried the factory reset but it still operated like that and there's no TWRP but the original recovery of android. Changed the cable , changed the PC , still nothing happened. Someone plz help !!!

Hello anyone have solution on this? I have same problem

I need help too.. please dear experts..
I flashed my A3000, but it stopped at 87% at stay there all evening ans night. So today I try to switch it on - nothing happens, long pressing buttons: nothing, dead device.
I connected it to PC, and in device manager it shows "unknown device" (not: mt65xx unknown device!) So it seems it is not completely dead!
I try to install the mt65xx driver, but I cant.
So any hint what I can try to revive it? I would apreciate anything very much, that you!
----
EDIT: Windows shows CODE 43 for the A3000. What can I do?

Solved..
I let the battery drain for some day, then after pushing reset button, It starts to load the battery again. Then it repeatly starts to boot every 3 seconds. Switching it off and try to flash it again - bingo! Everything is fine again

Tanix TX2 Rockchip RK3229 , flash via Uart , help.

Hi, so i am having issues with my Tanix TX2 RK3229 2GB/16GB box , i am in the process of a paypal dispute over this but if i can find a solution myself i will be more than happy to just DIY.
Basically the box froze for no reason and now will not go further than the ANDROID screen , i can boot into recovery but the only available update i can get is the 7.1 update which fails ( for me and many others ) all other firmwares including stock are .IMG and recovery does not see them on the SDCARD, the device is NOT picked up by my PC when connected via USB to USB , so , the only way i can see past this issue ( unless a magic version of the stock firmware arises ) is to try and flash via Uart ( i assume thats possible ) but i have zero experience with tv boxes , Uart and quadcopter flight controllers Yes tv boxes Nope.
Is there a really simple set of instructions on flashing a tv box via the Uart that i can read over ? or a simple way of turning the stock firmware.img into a firmware.zipp so that the recovery can use it to flash back to stock ?
I would be grateful for any pointers in the right direction
