Hi Guys,

I have a Problem with my A511 and i send the Tab to Amazon back.

How can I delete the recovery again?

I've tried to flash the Stock Rom (Acer_AV041_A511_1.011.00_WW_GEN1) But it did not work because my Acer A511 is a german Tab with german Stock Rom (Acer_AV041_A511_1.028.00_EMEA_DE).

Thank You

Sorry for my bad englisch :/
[Acer Iconia A700 and A510] BENETNATH:
the best way would be to have access to adb, and to push the stock recovery with dd command.

but it will not remove the unlocked bootloader, as would a new firmware
[Acer Iconia A700 and A510] FordSierra88:
Can you tell me the exact command?

Thank you :)
[Acer Iconia A700 and A510] nikagl:
I haven't been able to test this but I think reverting to stock recovery isn't that difficult. Try the following:

1. Rename the file back (step 12 in OP):

adb shell
cd /system/etc
mv install-recovery.old install-recovery.sh
mv install-recovery.oldnika install-recovery.sh
mv install-recovery.offsh install-recovery.sh

2. Do a Factory Defaults reset using the Vol+/Vol-, Poweron, toggle rotate switch method (this will take place immediately!)

3. Reboot several times

During these steps the following will happen:

1. The fact. defaults will clear root

2. The rename will install the recovery at some place (therefore, reboot several times)

If you really want to install the 1.011 rom you will have to remove the first line (assert blah, blah) and sign the rom back or install it with cwm... but that is... dangerous... ;)

Regards,

Nika.
[Acer Iconia A700 and A510] FordSierra88:
I'll try to report about it later :)

Thank you this little "hwo to" :)

Hi nikagl,

i need to install the stock recovery as well and tried what you have described above. But I don't have the install-recovery file in system/etc

I installed CWM and rooted with your root-a51x.zip.

I also tried to install the stock recovery you have posted on the first page with adb, but when I try to boot into recovery, there is only the Android lying on his back with a red warning sign.

Btw, the A510 and the A700 don't have custom roms yet. Are there any problems with our tablets or are there simply no devs atm?
[Acer Iconia A700 and A510] nikagl:
I wish I could test for you, but as most know, my A511 is bricked. Even worse... I cracked the screen last week (laptop bag in which it was waiting for an "unbrick" fell on the floor).

Attached is the recovery bits from the 1.011 ROM. It should add:

/system/recovery-from-boot.p

/system/etc/install-recovery.sh

Try that. I have also made one which additionally replaces "/dev/block/platform/sdhci-tegra.3/by-name/USP" with "bootloader.blob" but I am not sure what that part does (sounds like replace the boot.img with a new version, but as we have not modified boot with the A511 I don't think we need that).

Btw, you can also simply extract the files from the zip and upload them with adb or use root explorer or something like that to copy it into the right location. Probably, in your case as you've already replaced the recovery with another version, that's the best method :)

Regards,

Nika.
[Acer Iconia A700 and A510] nikagl:
One more thing, just to make sure, you are using an A510 or A511? This is a recovery for the A511 - the A510 I think the stock recovery from the previous post is sufficient. Not sure whether it should show you anything else than the Android on it's back as stock recovery doesn't have much other options...

Last but not least, not sure why your recovery shell file is not there anymore. I really just rename (mv) it in the script:

run_program("/sbin/busybox", "mv", "/system/etc/install-recovery.sh", "/system/etc/install-recovery.oldnika");

Regards,

Nika.

There are Devs, but without a solid working recovery, there's not a lot anybody can do with developing custom roms/kernels. Once we all get a reliable recovery, other things will come.

[Acer Iconia A700 and A510] BENETNATH:
indeed,i've got already a build on jelly bean, but not very keen to test it without a little parachute, let's says a working recovery :)
[Acer Iconia A700 and A510] Moscow Desire:
I hear you mate. I'm sitting on a new kernel that fixes a lot of issues/shortcomings, but no way to try it. They have a new recovery out in the 700 forum, but the jury is still out on whether it fixes the brick issue with the 70x and 51x.

And I used up my warranty, so no risky business till Recovery is fixed ;) Also waiting my tab from repair.
[Acer Iconia A700 and A510] BENETNATH:
You've got a boot.img ?

If so, might give a try through fastboot, no?
[Acer Iconia A700 and A510] JustFlesh:
@nikagl thank you, but my problem wasn't the recovery. The update failed because I deleted some system apps. I thought the recovery was broken as I saw the android with the red warning signal :D

Great to hear that some of you are already working on making our awesome tablet even better :D

I'm a flash addict since I had my first android phone, and I can't wait to see JellyBean running on the A510. It seems that the guys over at the A700 forum making good progress on their recovery. Maybe we'll get a working recovery as well soon.

Gesendet von meinem A510/sent from my A510
[Acer Iconia A700 and A510] BENETNATH:
Moscowd, did you make all the mods to the ramdisk files to match the bootclasspath of Jellybean ? (like init.{device}.rc, uevent.{device}.rc, etc.) ?

seems mandatory to have a JB boot
[Acer Iconia A700 and A510] Moscow Desire:
Actually, it was based on 4.0.4. Never got a chance to test it. Some mods we use on the 500/501 especially GPS.

The prime thing, is that there "are" people willing to push this thing past stock. Heck, I had a themed rom already in work when it bricked. So much for that. (will probably get a different OS, and we know the kernels are probably tied to the specific version bootloader.

The first thing, and most important, is a working recovery. We all know this. Thanks to some of these folks for taking the risk to get it going.

Supposedly the newer CWM in the 700 forum works and doesn't brick tabs. So maybe some info can be gained for the 51x and when he gets his tab back, he can get a fully working CWM. Hopefully.

So I'm not going to clog the thread anymore, as really, it's off topic. Sorry OP.

[Acer Iconia A700 and A510] BENETNATH:
in tegraowners, seems that acer recovery installer works to backuo/restore the A510.. don't know if i can put the link ?
[Acer Iconia A700 and A510] Moscow Desire:
Everybody knows where tegraowners is. Please don't take Nikagl's CWM in this direction. Nikagl has this thread, and when he get's his tab back, I am sure better things will come. Let's leave tegraowners out of it. And no, you can't put the link here. ;) (I think you know better ;) )

[Acer Iconia A700 and A510] BENETNATH:
just speaking about recoveries..
[Acer Iconia A700 and A510] FordSierra88:
Hey Nikagl :)

I have my new A511 because my old was a processing error.

I could test it with my old A511 and Backup hass working without Bricking the A511.

So it all worked, but a little buggy :)

Thank you

Greeetz
[Acer Iconia A700 and A510] BENETNATH:
could you be a bit more specific please ?

what type of backup (data included ?),

what was a bit buggy ?

what firmware did you have on the tab ?

thanks
[Acer Iconia A700 and A510] nikagl:
Yes, my backup worked fine too. BUT when I restored that backup, it killed my tab, so be really, really, really careful, better yet, honestly, do NOT restore a backup unless you want to send it back to repairs (or have a working APX restore method / nvflash)!
[Acer Iconia A700 and A510] BENETNATH:
nika,

do you think it as a link with the data partition ?

i've tried another recovery, the backup bugged when taking data partition, when i tick off the data through advanced backup, it went fine..
[Acer Iconia A700 and A510] nikagl:
In my case the backup stopped during restore of system. I then power off and it never powered on again...
[Acer Iconia A700 and A510] BENETNATH:
this, i can't understand..

how could it be bricked so much that i does not even power off..
[Acer Iconia A700 and A510] nikagl:
It just stopped during the restore of system and didn't continue. I am not sure how I then powered off (several hours later, the next morning), I guess by long-pressing the power button as it did not respond anymore. When I then tried to power on it didn't turn on anymore, just APX mode on the laptop :(

Btw., it was the Touch Recovery created through the CWM-builder website. I guess that builder is not as stable as I expected. I was still in the process of creating a newer build on my Ubuntu partition. The CWM recoveries without touch were based on my Ubuntu (with the kernel from boot, not manually built from source)...but... my Ubuntu image crashed the same day as the tab bricked because of a harddisk fail (one of those lucky days!) so I cannot get anything back. Sorry...
[Acer Iconia A700 and A510] BENETNATH:
no trouble

i'll be glad to help to build a cwn recovery from source.

any tuto around that?

any advice ?

i've got a VM ubuntu which seems ok, as i was able to compile a system.img from AOSP (not tested)
[Acer Iconia A700 and A510] nikagl:
I haven't found any. Just the one for building recovery from a boot.img (see first post, the website from Koushik). PA advised some of the following sites for building ROMs from source, but I simply do not have the time to look into them:

CWM - now OTA update does not work

I also installed CWM and was stupid enough not to make a backup of the stock recovery. Now the OTA (I´m in Germany) does not work, the android goes dead turtle.

So: how do I go back to stock recovery? Acerrecovery won´t do it, when I choose to install backed up recovery I end up with CWM recovery again. Or: Is anybody knowledgable enough to make a CWM flashable .zip from the latest Acer OTA update?

The A510 is really nice, but one drawback seems to be that they shipped only a few, so the community is really really small and we don´t have a solid recovery an no custom roms - while e.g. my motorola Atrix runs Jellybean from Jokersax really well. I hope we´ll be getting there..

edit: cross-post, @nikagl: just saw that you posted the stock back-up. Thanks alot!
[Acer Iconia A700 and A510] nikagl:
What device do you have? What ROM? See first post for uninstall instructions.
[Acer Iconia A700 and A510] nikagl:
Didn't Randomwalker post the new German OTA? Here it is:

http://xdaforums.com/showthread.php?t=1790948

Try the zip in that download - should also be CWM-installable.
[Acer Iconia A700 and A510] Doolittle Duckbill:
Is it possible to install the stock recovery with your CWM or do we have to push it with adb?
[Acer Iconia A700 and A510] nikagl:
It's a push through unlocked bootloader, similar to how you installed the CWM. CWM-installable can also be created but might cause unexpected results... so I'd prefer not to do that :)
[Acer Iconia A700 and A510] Doolittle Duckbill:
No, that one is like the OTA: Android going dead turtle with exclamation mark
[Acer Iconia A700 and A510] nikagl:
And no error message? Interesting - maybe it has a different ro.product.name?

Can you run this from cwm? First mount system from the mount menu and then run the following command from adb shell:

cat /system/build.prop | grep "ro.product.name"
[Acer Iconia A700 and A510] Doolittle Duckbill:
That does not work. I successfully pushed the stock recovery with adb. It says writing `recovery` ... OKAY

Any further adb commands get: error: device not found and I have to hard-reset with a pin. The OTA still gets dead android and on reboot recovery I now dont have CWM any more, only dead android

?
[Acer Iconia A700 and A510] nikagl:
Then the problem is not the recovery but the OTA file you're using. Did you format the sdcard to FAT32? And did you try to get the build.prop to see what ro.product.name you have? I am quite sure the OTA fails because the first line in the OTA (assert....) checks that file and has a different product.name. Maybe try an older version OTA for your device? Try to make sure to use a version that is the same as your ro.product.name...
[Acer Iconia A700 and A510] Doolittle Duckbill:
I reinstalled CWM:

/system/etc # cat /system/build.prop | grep "ro.product.name"

ro.product.name=a510_emea_de

BTW:

running /system/etc # mv install-recovery.sh install-recovery.old

gives

mv: can't rename 'install-recovery.sh': No such file or directory

So right now I´m stuck. I never installed any roms but what was originally on the A510 when I bought it in Germany. After that, there was one OTA that I installed when I still had the stock recovery, about 2 months agon. After that I installed CWM recovery. Now it tells me theres a new OTA update, but it wont install but instead gives:

Installing update...

asert failed: getprop("ro.product.name") == "a510_emea_de"

installation aborted

I tried to find stock roms with _EMEA_DE in the file name, but none can be flashed with recovery. What a pain in the ass! God how I love my Cyanogenmod mobile phone!!!!!!!!!!!
[Acer Iconia A700 and A510] nikagl:
1. I would install a different stock ROM, not the FOTA. Just leave the FOTA like it is. I couldn't find another EMEA_DE stock ROM though. It looks like the FOTA builds available for download and EMEA_DE are not full ROMs? Maybe ask in the other FOTA or stock ROM threads. Possibly it's better to use a ROM for another region (like emea_cus1)? I do not know though whether that has the assert message in it:

Acer_AV041_A510_1.060.00_EMEA_CUS1

2. If it cannot rename the sh file, it must have been renamed already. Do a "ls -la /system/etc/install*" from adb shell to see what files are available. If you have another recovery, it shouldn't be available anyway because it would revert recovery to stock when you boot your device.

I am not available during the rest of the day, so please do not expect more responses today...

Hi there,

Thank you

edit: for a510
[Acer Iconia A700 and A510] nikagl:
Stock or CWM? In both cases see first post. But currently my advice would be to not install any recovery because backup/restore and any of the format commands are probably causing bricks!! CWM can only be used for installing cwm-installable files at this moment. For A510 there is at this moment no real use to do that.
[Acer Iconia A700 and A510] Doolittle Duckbill:
exactly what my problem is - though you described it more detailed
[Acer Iconia A700 and A510] Sony_Simon:
i had emea_de too, but i deleted some stock apps and so i cannt update the firmware.

now i testet for some hours every rom, in my last post on the site 15 i had a little list what roms work (recovery -> update.zip)

there is no emea_de full stock rom at the moment maybe anyone can get such firmware that would be really great!!!
[Acer Iconia A700 and A510] nikagl:
As far as I know when the update-script runs getprop("ro.product.name") == "a510_emea_de" it does it on the build.prop in your /system. That's why I always ask for cat /system/build.prop | grep "ro.product.name"... so it's not part of whatever the recovery does or is, it's which ROM (the update.zip containing the updater-script) you are trying to install onto which other ROM (the one on your device).

The only way around would be to remove the assert command in the beginning in the updater-script, zip the whole thing again and try to run it from cwm. That would overwrite the rom you have regardless of the version, but could cause issues as the rom is possibly not written for your device. Please note that most custom roms do not have that assert command and would be just as dangerous...
[Acer Iconia A700 and A510] en4cer1970:
Why do not you reinstall the deleted apps? Download the latest A700 full german firmware, extract the missing apps and copy this into /system/app or /flex/app.

Changing the file permission. Reboot and update. Yes the A700 firmware contains many of the same apps, like the A510 before the update.

Look in your update log, which apps are missing: /cache/recovery/last_log

Which file in which folder is can you see here. This is a system backup of my A510 after update.

Not sure why your device does not allow adb from cwm. Is the cable or usb port faulty? All drivers installed?

Weird. I definitely had it... when my device still worked. Initially I had done the rename steps in 10-12 with adb from my recovery. I am 100% sure it worked for me like that. So I'd assume it's drivers? Maybe some debugging stuff I still have left from other devices?

[Acer Iconia A700 and A510] :
The CWM from Acer Recovery doesn't do anything when I try to install the last update.zip (19mo). It returns to the main menu and that's all. It do same when I try to install a rom from the list you provide.

Is the A510-stock-recovery.zip (4.48 MB) you provide allow to install update.zip when it's put on sdcard ?

I look at the .bat and the following lines should do nothing for me as long as I do not have thoses files (install-recovery.sh backup) :

adb shell su -c "mount -o remount, rw /system/ ; mv /etc/install-recovery.offsh /etc/install-recovery.sh;"

adb shell su -c "mount -o remount, rw /system/ ; mv /etc/install-recovery.old /etc/install-recovery.sh;"

adb shell su -c "mount -o remount, rw /system/ ; mv /etc/install-recovery.oldnika /etc/install-recovery.sh;"

The "fastboot flash recovery A510-stock-recovery.img" command is enough ? I don't know if my install-recovery.sh has been changed can you provide the original ?

Thanks
