FIXED - Acer A200 - BRICKED, cannot mount /data /sdcard

Didn't see a way to edit the title. As for rooting, note that after all was said and done, I am still not rooted. I just managed to get updated to 4.0.3, which should have been done OTA anyway. I may try again now that I am a bit more confident that I can get it back to working state, but will do a full backup in ADB first. Too much of a pain in the *** to have to reconfigure everything again once the OS is installed.
[Acer Iconia A500] crazyjimbo:
I cannot get the device to connect to my PC at all, or get the correct driver selected. Any tips?
[Acer Iconia A500] j_medved:
what state is the tablet in when you try to connect? Fastboot, Recovery, or fully booted up and operating?

What do you see in the device manager when the tablet is connected?
[Acer Iconia A500] teacherhh:
ext3 oder ext4?

1) /SDCard would not mount. Solution - PARTITION the SD card. NOTE: The card worked on a PC, and even on that tablet when Android was fully booted. However it would NOT mount in recovery until I explicitly partitioned it. Doing a FORMAT on the PC does NOT count. I had to partition it within Recovery.

Try to do this with twrp v.2.1.4: do I use ext3 or ext4 for the Partition? And which size needs the ext Partition?

Thanx

[Acer Iconia A500] j_medved:
Don't think it matters. I picked the defaults.
[Acer Iconia A500] teacherhh:
mke2fs -j -b 4096 /dev/block/mmcblk0p8

Thanx j_medved for yor reply!

So I did and just faced the next problem: I can conect my Tablet to the PC and can finde it with adb devices and can start the shell with adb shell.

But then when I start: mke2fs -j -b 4096 /dev/block/mmcblk0p8

nothing seems to happen....waited about 30 minutes....

in the next turn I get the reply, that mmcblk0p8 is allready in use....next turn again: nothing seems to happen....

any ideas? .-(

Driver Problems

Hi Guys,

I've the same problem. I can't wipe the Data, so I've found this instruction. unfortunenately will my PC not found my Tab. I've installed the drivers many times, but it will not work. Can anybody help, how to install? btw. fastboot is working, but not adb.

I'm using an Samsung Netbook with Win 7. THe PC's trying to install drivers, altough they are already installed, but can'T find any drivers.

If you need more informations, just let me know.
[Acer Iconia A500] j_medved:
@Benninator,

If you look in Windows 7 Device Manager, does the device show up there OK? Or does it show up as unrecognized device, or as some device code with a yellow triangle and exclamation on it? Or not at all?
[Acer Iconia A500] Benninator:
Yes, their is a yellow triangle. I've tried to install the driver manually, but with no success. In my driverlist were the Acer driver not listed. furthermore I've tried to configure the usb-adb.ini with also no success. I have absolutly no idea what I can do.

what can i do to get adb working so i can fix my mount issues so i can install my room again ?

hope you can help me tnks
[Acer Iconia A500] j_medved:
I assume you mean CWM? I had problems with CWM on the Acer. ADB would not work. That seemed to be a known issue (have not checked lately). When I setup TWRP Recovery, everything worked fine.

Try TWRP. If you sill have a problem with Windows drivers at that point, check the device manager. If you see A200 in there with a problem icon, try right clicking and explicitly specifying the correct driver.

Unlocked Bootloader following A200 Wiki page

Installed Nic's TWRP 2.1 stable from wiki page

No SD mounting, external doesn't mount either. USB storage doesn't work either. A device called A200 appears in Computer Management, so I installed Acer ADB Composite Drivers
[Acer Iconia A500] j_medved:
Roy360,

Don't know what to do at that point. I haven't messed with the A200 for over a year.
[Acer Iconia A500] Roy360:
sigh... I've got two of these tablets lying around with no rom. Both have unlocked bootloader but one of them gets some magic mismatch error after I wiped the kernel, and both of them can not mount /sdcard and /system.

Not even partitioning it works. /Sdcard and /system are always unmountable. Yet I was still able to access the internal storage when the tablet was still able to get into the rom
[Acer Iconia A500] Jdiel316:
Agreed

Hey man, I am having the exact same problem as you. Sadly it looks like there isn't much going on with A200 troubleshooting these days. I bought this off a friend a couple weeks ago, and after obtaining unlock mode am in the same boat. Can boot into recovery, but Fastboot no longer recognizes my device, and TWRP won't fix the SD card issue with repartitioning. Have you tried, or come across anything else?

Cheers.
[Acer Iconia A500] Roy360:
The fastboot issue can be resolved with the proper devices. After install the Android SDK manually select your device and install the Acer ADB drivers. However I still having issues with SD card repartitioning. The rom recognizes the SD card so why doesn't recovery?

I've tried installing roms thru fastboot, but the A200 seems to read all the partitions besides /recovery differently.
[Acer Iconia A500] Roy360:
I made a little progress. since my last try

fastboot boot boot.img <- with some boot.img I found on my computer (not sure if custom or stock)

now I don't get the magic error anymore. Acer logo screen does this werid thing for a second and goes back to normal

thor recovery's touch doesn't seem to work properly anymore, but CWM and NICS are fine. But I still can't access the damn System and data paritions.

So I decided to break out the A200 and play around a bit. Got it rooted and unlocked, then I tried to install a recovery......unfortunately I grabbed a recovery for the A210, not the A200.

I tried to get into recovery but get the Droid on his back with an error......so I cant apply any update zips..........Any ideas? I know its an old tablet and thread, but hate to ditch the tablet.

It only says mke2fs 1.41.0 (DATE..2010 or something) and then.. Nothing more.

[Acer Iconia A500] sniperbag:
Hey guys,

I'm happy I found this thread. I wanted to use my a200, it has been laying in the back of my room for a long time since I bought my HTC one m8. Now when I start it up I only get the unlock mode Acer screen and nothing more.

So here it started I tried this so far:

Tried to get into recovery -> Android with red exclamation mark

Tried custom recoveries -> they do work but I'm unable to mount anything (cache, sd, data etc.)

Adb shell does not recognize (on win 8.1) my phone and I've tried everyy driver possible.

I know I'm just right before a breakthrough. I feel like I have to find it to mount sd or data so I could flash a stock or custom rom with recovery. Or maybe there is a way to flash a rom as image through fastboot?

Cheers.

Hey guys, First off I need to give the devs for Vicious Jelly Bean high praise! I am having an issue with Faux beta 19 1.8Ghz kernel.

It doesn't sound like your GNex can function properly while OC'd that high.

Why is that necessary on this device? I'm actually curious, not being a smartass.
[Samsung Galaxy Nexus] pjflo:
This sounds very dangerous to me..

The omap4460 (cpu in GNex) supports frequencies upto 1.5ghz.

pushing it higher can only cause problems, maybe not short term, but it will deffinatly cripple the lifespan of that cpu.

Not trying to be a smartarse or owt here, just a conserned bystander.
[Samsung Galaxy Nexus] sshede:
True but the phone probably won't last long enough for that to matter. As for OCing to 1.8Ghz, I've yet to hear a single good reason why. The OMAP4460 is powerful enough at 1.2Ghz.

Is there any way to make the screen brighter like increase the maximum brightness i find the screen to dim for my liking

[Samsung Galaxy Nexus] Postpucio:
Poor screen bright

Hi,

I purchases a Nexus last week and also noticed a very poor bright on the screen, like a joke. I went back to the shop and took a look on another 2 Nexus, finding the same problem. All of them were brand new

It came with ICS 4.01, after updating to 4.04 and make a hard reset, the screen became much brighter than before. I thought the problem was solved, but after only 5 minutes it went back gradually to the dark scene. Even at maximum bright, it was really dark. So I guessed there was something wrong with the kernel or the stock rom. Maybe the paranoia to "save the planet" makes the system to low down the brightness screen.

However, I have a friend with same phone and his screen is as bright than can not be seen at night without almost burning your eyes. So I asked for which rom he was using and I install the same one. And Hooooops !!! VERY very bright after the first reboot. Try it, it works. It is working for more than 1 week without dimming the brightness again. Here's the link:

I dont like putting cases on but sometimes I feel like I'm going to drop this thing from being so thin. I've narrowed my search down to these:

skull candy:

pros: like its slim design and fit. power button nicely accesible.

cons: gloss finish

barely there:

pros: nice matte finish. good for grip. nice slim design and fit.

cons: power button looks a little hard to get to.

Incipio:

pros: love the metallic look and nice slim design and fit.

cons: power button not clearly accesible. (like barely there case)

zagg full skin:

pros: will probably provide some grip and keep it's thin profile.

cons: less protection from drop and camera.

I like to go with the cases because my main concern is protecting the camera when I place the phone down but I want something that keeps its slim profile and grip so I dont drop it.

Also, those who have these type of cases, do you find that alot of crap and dust builds up in between the case and phone or is the fit tight enough to prevent this?

your thoughts?
[HTC One S] klin1344:
I personally use the diztronic case and its the best case I've ever had on any phone. It fits tight so dust doesn't get between the case and the phone and its just thick enough to protect the camera when you lay it on a table. Don't get me wrong, its still very very slim and in my opinion gives the phone a nicer feel.

Yes, its supposed to show.

Try going to settings --> sound and see if DSP manager is available under music effects

Doesn't matter that you wiped them, as that shouldn't touch your apps or the partition where your apps are stored.

Try flashing beats+xlouder from the development section, and flash the dspmanager zip from that thread on top. It should show up then.
