Ah, i dont know whats going on here, now i get the "more then onde device or emulator" error and it shows me the device like 10 times on adb devices. Even adb kill-server let me run the mount phase, but after that i cant boot in bootloader because adb reboot-bootloader is not working anymore cause of 10+ devices (all offline.)

Im using Acers USB Drivers.

good night.
[Acer Iconia A700 and A510] FloatingFatMan:
It never will either, on -any- VM. The USB bridging drivers they use interfere with how ADB works. You'll need a native Windows or Linux machine.
[Acer Iconia A700 and A510] mongocliqque:
I never had any problems working on my Arc in VMBox.

It shows me the Acer ADB and the Acer A511 in the Device Manager.

I think its more the problem that i have adb drivers installed on that Box for like 4 different devices. Will try to make a clean Box ONLY for A511.

But well, its always the first time, isnt it?

:angel:
[Acer Iconia A700 and A510] FloatingFatMan:
Well, it's never worked for me, on multiple different VM's, on different hosts. The USB bridge driver always interferes and causes unpredictable results.
[Acer Iconia A700 and A510] nikagl:
And I've never had any issues with drivers for at least 10 android devices installed on my laptop. I also used ADB through my Ubuntu VM and have not had any issues either...
[Acer Iconia A700 and A510] nikagl:
I have uploaded a A510 recovery. Built with the boot you provided, using the CM Builder and the recovery.fstab mentioned before it should provide the same type of CWM as for A511 but now with the A510 kernel.

Again, backup seems to have issues with /data (in my case) and DD-ing is troublesome because it's 32 GB...so in all cases, make sure you wouldn't mind starting new with your data (ie. program settings etc.) if something fails.
[Acer Iconia A700 and A510] daisura:
thank you for all this effort!! I have been waiting far too long for this to come up. It's really exciting to finally see people working on this tablet, this tablet is far too good to be put aside
[Acer Iconia A700 and A510] paugustin:
Hi I'v got an A510 stuck in a bootloop (acer logo). It will not boot no matter which update I flash.

I flashed your recovery hoping to flash from there with better luck unfortunately my tab won't boot CWM using vol-/power. It will only prompt me for the standard recovery but fails to load any update now.

bootloader is unlocked, flashing CWM through fastboot was successful but for any reason it will not show up ! I've seen this on another tab that will only boot CWM using adb reboot recovery. Unfortunately I can't get the tab to boot in a state that allows this command.

Any idea ? maybe if someone had a stock recovery I could flash back ?

Thanks !
[Acer Iconia A700 and A510] azreen91:
I'm using A510. if I flash to CWM recovery, will I lose all my data? no? sorry for a noob question! haha.
[Acer Iconia A700 and A510] BENETNATH:
stock recovery is there for A510

https://dl.dropbox.com/u/91092/recovery.img

then you may try to put a EMEA firmware like this one :

Acer_AV041_A510_1.060.00_EMEA_CUS1

available there

http://narod.ru/disk/48315641001.b2...7/Acer_AV041_A510_1.060.00_EMEA_CUS1.zip.html

you should rename it to update.zip and put it on external sdcard, and boot with volume down pressed.

ADDITION : otherwise, you can check this one :

http://4pda.ru/forum/index.php?showtopic=337486&view=findpost&p=13370502

no, modification of recovery does not modify you data or system partition.

anyway, a whole backup with titanium backup is still a good choice before any modifications.
[Acer Iconia A700 and A510] simoneser:
You have the same problem I had on my A511...but on my tab the situation worsened and now it doesn't wake up anymore :(

It goes only on APX mode and I can't unbrick it because there are no methods for NVFlash with A511 (only A500, but it's different). And I don't have my CPUID.

:(
[Acer Iconia A700 and A510] paugustin:
Thanks BENETNATH, unfortunately it's not enough. I'd like to try and flash boot.img, recovery.img and system.img by hand through fastboot as everything else fails.

Could you upload boot and system ? If possible not on dropbox because I'm behind a proxy that does not like dropbox :D You can try demo.ovh.com ;)

I know it's a big bunch to upload and I won't mind if you don't have the time/patience.

Cheers,
[Acer Iconia A700 and A510] BENETNATH:
i may send that tomorrow only, but why don't you take that files from the 1.60 firm i gave to you ?

just unzip and flashboot directly the img, no ?
[Acer Iconia A700 and A510] paugustin:
update.zip does contain the system.img, only recovery and boot. Maybe it's possible to creat a system.img from the update.zip but I don't know how.

If I can't sort it out, I'll wait for your upload ;) Thanks in advance.

(C'est bien la première fois que je galère tant. Au moins pour ma A501 j'ai tous les nvflash qu'il faut :D)
[Acer Iconia A700 and A510] nikagl:
Creating system.img from an update.zip is almost impossible. img files are dumps so you'd have to create an ext4 partition somehow, copy the files from the zip and make a dump. I tried it for samsung in the past but always failed when restored the image probably because of partition size, block size, etc.
[Acer Iconia A700 and A510] BENETNATH:
ok,

will get it out from my tab.

nikagl, just wondering if you have th skill and spare time to port some CM9 on our A510/511 ??

cause the stability issues are a bit freaking some times..

EDIT :

just to confirm

dd if=/dev/block/platform/sdhci-tegra.3/by-name/SOS of=/mnt/sdcard/recovery.img
dd if=/dev/block/platform/sdhci-tegra.3/by-name/LNX of=/mnt/sdcard/boot.img
dd if=/dev/block/platform/sdhci-tegra.3/by-name/APP of=/mnt/sdcard/system.img

are the one to use ..?
[Acer Iconia A700 and A510] nikagl:
For A510/A511 yes, but didn't your tab stop to boot? Edit: sorry, mixup, that was simoneser....

And CM9... never did that...sorry, still learning ;) and definitely no time :D

Problem with CWM

Hi together,

I got my A510, rooted it, unlock and install the recovery "A510-recovery-cwm-5.8.4.5-touch". I boot into the recovery and everything looks fine.

But, here is the trouble. I cant use the touichscreen (nothing happens), but I can work with Volume-buttons and the Power button. But it is not possible to do something with it. If I want to "backup/restore", I only the the CWM-logo in background and nothing happens. I can click on "Reboot system", but nothing happens. So it is not possible to backup/restore anything.

What is wrong with it? Everything else (root, unlock...) worked perfect.

My FLEX-Version is Acer_AV041_A510_1.076.00_EMEA_DE

Thanks for your help!

[Acer Iconia A700 and A510] nikagl:
Hallo Ankabo,

Touch recovery does not have the options going back (extra menu item) and forward (select with power). Touch is supposed to work, so if it's not I guess the boot.img I got somewhere is incorrect. Do you know whether your FLEX version can be downloaded somewhere? Or can you export the boot.img? I can then try to build the Touch CWM again (through the CWM builder). If that fails, I can also build a non-Touch CWM but fot that I need to setup an extra repository for the A510 so that takes a little longer (a few days as I really don't have much spare time at the moment).

One other question: how do you root your device? I have seen several options, and one of them requires install of a custom boot image. The others mostly are scripts that use the mempodroid exploit...

Regards,

Nika.

[Acer Iconia A700 and A510] ankabo:
Hi Nika,

I used these guide root the tablet:

http://xdaforums.com/showpost.php?p=25036001&postcount=93

Than I used the adb command to unlock and after that I flashed recovery with your files (executed .bat file).

Do I have to clear some caches or something to work?

Sorry, but I´m new "to the game" ;)

Regards

Andre
[Acer Iconia A700 and A510] BENETNATH:
I've got exactly the same behavior on mine..

recovery is launching, but power button only hide/display the interface, and logo remains visible..

i made again the boot.img in case of some mistake .. :

https://dl.dropbox.com/u/91092/boot.img
[Acer Iconia A700 and A510] nikagl:
Hi Andre,

Ok, very good. So the rootkit is the one based on the mempodroid exploit (or however it's called :D). That's fine, shouldn't matter for the recovery. Clearing cache, etc., is not relevant to a recovery which is all "standalone" and does not depend on anything else on your device.

On the device, can you do the following?

1. Start the device (normal)

2. Enable USB Debugging

3. Connect PC

4. Run the following command:

su
dd if=/dev/block/platform/sdhci-tegra.3/by-name/LNX of=/mnt/sdcard/boot.img

this will simply export the LNX partition of your device which is the boot image to a file called boot.img on your sdcard (if = inputfile, of = outputfile)

5. Transfer the file to your PC, zip it and send it to me (or us, it doesn't contain any "private" information)

I will build a new Touch CWM (with the builder website) which you can try.

Regards,

Nika.
[Acer Iconia A700 and A510] nikagl:
lol, i was already binary comparing your boot to the one i used... more news soon :)
[Acer Iconia A700 and A510] nikagl:
Well... they are binary the same. Not sure, but it might even have been you who provided me the first boot.img? Nevertheless, I'll try building it again with the builder, and if that fails I'll do it manually for a non-touch-version...
[Acer Iconia A700 and A510] ankabo:
Puh... Some errors...

"Cannot open for read, permission denied" at the dd-command.

I tried "adb remount" - remount failed: Operation not permitted

Edit: I think I have to do the dd-command on the tablet, right? If it is so, my mistake ;-)
[Acer Iconia A700 and A510] nikagl:
Sorry... try "su" before running dd... Oops... forgot that! Modified the instructions above :)
[Acer Iconia A700 and A510] nikagl:
And for learning purposes. "adb remount" doesn't seem to work. What works is "mount -o remount, rw /system/" in a shell after su (ie. prompt is # instead of $). After that you can write stuff in /system, but for dd you only need su.

adb shell
shell@android:/ $ su
su
shell@android:/ # mount -o remount, rw /system/
mount -o remount, rw /system/
shell@android:/ #
[Acer Iconia A700 and A510] ankabo:
Another problem, I think I go to bed for today...

adb shell

su

dd if=/dev/block/platform/sdhci-tegra.3/by-name/LNX of=/mnt/sdcard/boot.img

Now records in, records out, but I see, that there is no "/mnt".

I tried "of=/boot.img", no permission.

Than "mount -o remount, rw /system/", command was OK.

"su" - "dd if=/dev/block/platform/sdhci-tegra.3/by-name/LNX of=/boot.img" = cannot open for write:Read-only file system

Edit: I´m stupid, I have to sleep... My mistake, wrong folder... boot.img now available.
[Acer Iconia A700 and A510] nikagl:
Haha, takes some troubleshooting, but remember, you're getting wiser now (not sure why you'll ever use this knowledge again though :D).

Weird that it cannot find /mnt/sdcard. Did you try /sdcard? And what happens if you do "ls -l /mnt" (dir command in unix)? Last but not least, you can also try /mnt/external_sd as a file path for boot.img. When you used /boot.img you tried to write in the root, and that's only writable when you mount it as rw (so "mount -o remount, rw /" -- without system/) ;)

Hi Benetnath and nikagl.

Thanks for the files I was able to download and flash them unfortunately it does not solve my problem. My tablet still bootloops. I guess it needs to be repartitioned completely. So nvflash seems the only way to revive it.

[Acer Iconia A700 and A510] nikagl:
So, you're waiting for someone to upload a backup (without data.img)? I can't provide it as I don't have an A510 but maybe someone else?

Right, looks like the A510 and A511 recovery files in the first topic work and the instructions help people to install it correctly :)

Perfect. Modified the first post and added multiupload downloads as the attachments seem to disappear. The A510 download (V2) is based on the boot image from ankabo. He mentioned this is the boot image for "Acer_AV041_A510_1.076.00_EMEA_DE" (just for reference :)).

Ehm, this is only a boot and recovery backup. I think he is most anxiously waiting for a "system.ext4.tar" file. And... best would be... if you can factory reset, enter CWM and make a backup and share that (it would be an almost stock-rom without any data like google accounts, etc)...
[Acer Iconia A700 and A510] BENETNATH:
Exactly !

If possible you can backup, wipe all, backup again a clean system to share, and restore your first backup:D
[Acer Iconia A700 and A510] nikagl:
I am testing backup/restore on my A511 now and will let you know tomorrow whether it succeeded because it is verrrrryyyyy slow. I guess make sure to connect the device to an external power source to make sure the restore is not going to cause a brick during a power-failure!

Please note that I did have a problem with backup before, but I think there was some corrupted data in my /data that caused the backup to fail... This time backup worked fine.
[Acer Iconia A700 and A510] ankabo:
Oh, Sorry for that! Now I understand what you mean.

I hope, that I can do it this or next evening (german time).
[Acer Iconia A700 and A510] nikagl:
Well... it's still at /system restore... guess it's not going to continue. Possibly due to the flexrom being in the way?

[Acer Iconia A700 and A510] nikagl:

Nevertheless, be very careful with backup/restore as this definitely killed it last night in my case.
[Acer Iconia A700 and A510] ankabo:
The restore kills your tab?

@BENETNATH: OK, than you have to wait with the Acer original backup. I don´t want to crash it, because it´s not a "test-tab", it´s for my girlfriend and you can imagine what happens, if I kill it ;)
[Acer Iconia A700 and A510] nikagl:
Lol, agree. Try to imagine what happens to me when I tell the kids they cannot "test" their games anymore ;)
[Acer Iconia A700 and A510] BENETNATH:
yep understand...

do you have any idea of what happened ??
[Acer Iconia A700 and A510] nikagl:
The restore was running fine, it said it cleared boot and then restored boot and was working on restoring system which just never finished (it got stuck). When I powered off and tried to poweron again it just didn't go on... I guess either the restore of boot, or the restore of system over the flexrom (which is also in system) somehow killed it.
[Acer Iconia A700 and A510] mongocliqque:
Just as question between, at The Moment i just want to root my 511,

So just flash cwm , Run the root script, reboot . Finished?

Bad to hear that ur tab is dead :eek:

Hope u or someone else will find a solution.
[Acer Iconia A700 and A510] nikagl:
That is correct :) Really just:

1. unlock bootloader

2. flash cwm

hey nikagl,

what's new on your side ??

did you bring your tab to fixing service ?

By the way,

which recovery.fstab did you use to build the CWN recovery ??

the one provided by dees-troy ?

when i try to create one from boot.img, i've got a really different one :

# mount point	fstype device	[device2]

/boot mtd boot
/cache yaffs2 cache
/data yaffs2 userdata
/misc mtd misc
/recovery mtd recovery
/sdcard vfat /dev/block/mmcblk0p1 /dev/block/mmcblk0
/system yaffs2 system
/sd-ext ext4 /dev/block/mmcblk0p2

as compared to dees-troy's one

/system ext4 /dev/block/mmcblk0p3
/data ext4 /dev/block/mmcblk0p10 length=-1048576
/cache ext4 /dev/block/mmcblk0p4
/misc emmc /dev/block/mmcblk0p5
/flexrom ext4 /dev/block/mmcblk0p6
/sdcard vfat /dev/block/sda1 /dev/block/mmcblk1p1
/boot emmc /dev/block/mmcblk0p2
/aboot emmc /dev/block/mmcblk0p8
/recovery emmc /dev/block/mmcblk0p1
/flex ext4 /dev/block/mmcblk0p6
/sdc vfat /dev/block/mmcblk1p1

in addition, i don't know how to set-up BOARD_FLASH_BLOCK_SIZE in Boardconfig.mk

indeed, cat /proc/mtd does not give answer from what i remember.

can anybody confirm ?

and what is the output of

cat /proc/emmc ?

hi guys,

i'm trying to root my a511 but i have a problem with it.

i flashed the recovery via adb. the dos prompt shows the message "writing recovery okay".

if i now want to boot into recovery via holding volume- and power button, nothing happens. there is a fast text on the screen were i can see something like "erasing..." but then the screen stays black.

i can boot the tab normally but i can't get into recovery mode.

can anybody help me? :)

thx and greets from germany

grobi
[Acer Iconia A700 and A510] nikagl:
Hi Grobi,

The quick text mentioning erasing is just that it's erasing the cache which it always does before entering recovery (for whatever reason I have not figured out yet :D), that's normal. The black screen means your recovery doesn't work yet.

Can you let us know what ROM you are using? It sounds to me the kernel of your device is different than the one used in our devices. We need to figure out how to dump your boot image to get a working recovery. I am not sure how, anyone else that knows?

Btw, and I will add that to the original post as well - backup/restore does not work. Make sure to (if the recovery works) only use the install zip features (which work fine), for for instance the rooting process...

Regards,

Nika.
[Acer Iconia A700 and A510] Moscow Desire:
Probably cause there's a boot to recovery (or similarly named file) in your /system that needs to be deleted (or better yet, renamed). Otherwise, everytime you boot your tab, it will overwrite your CWM recovery. Should have been renamed during the root process.

But you might want to rethink installing the current CWM. If you haven't read the threads, and also the 700 threads as they both use the same CWM, it will corrupt your /Data partition if you try to either do a backup restore, or wipe/format data. And you can't recover it. Essently it bricks your tab as it will have to go in for repair.

I'm surprised the OP didn't place a warning that it's not working, and only for testing. He bricked his own tab doing a restore. Along with a few others and also in the 700 forum.

MD
[Acer Iconia A700 and A510] nikagl:
The warning is (and was!) in there (in red). I had another in there (update FOTA possibly causing bricks) and added a fourth in there and made those two orange.

At the moment this is the only way to root A511. Unless you have seen other methods? And yes... the rename of the recovery shell file is in there too... and you are correct, I have added that in the root-zip as well, just to be sure...

Last but not least, I will add it in the topic header as well...I guess that's all we can do for the community at the moment :)
[Acer Iconia A700 and A510] nikagl:
I only now saw your edit about the fstab. Yes, I used the Dees-Troy but I compared it to /cat/mount and other of those commands to see whether the mount points were the same and they all matched to what was in my (unrooted and stock recovery) device. For the recovery I built myself (the non-touch versions) I also used the settings in his Boardconfig.mk file which also matched to whatever I could list from my device. Too bad, but together with bricking my A511 I also bricked my harddisk (same day, believe it or not!!) that had the Ubuntu vm with which I built these and I had not been able to upload it to github yet :( so other than what is here, I do not have any backup of all the stuff...sorry...
[Acer Iconia A700 and A510] grobi1209:
Hi guys,

I've managed to boot into recovery and to install root with the zip. I've unistalled a few stock apps from acer and google with RootExplorer (Titanium Backup doesn't work).

Until now everything works fine.
