yep what pio said:

I had forgot all about this, even though it is in my unreleased linux auto installer. If by chance you are using linux, I have an installer that will do this all for you the right way, I just haven't posted it yet because I don't have the windows installer fixed

you can either download the linux installer git repo and just extract it to a directory named twrp_install or similar; just run sudo bash ./install-linux.sh after you are in the install directory. https://github.com/godmachine81/Acer-A100-TWRP-Installer/zipball/linux <<current linux installer for a100 twrp

Or you can clone the repo

git clone https://github.com/godmachine81/Acer-A100-TWRP-Installer.git

then checkout the linux branch:

git checkout linux

then install:

sudo bash ./install-linux.sh

The git method requires you have git installed, you will probably just want to install from the zipball method if you don't already have git ;)

aahhhhhh. thought it was something of that nature. now will i have to delete/rename and reflash twrp every time i need to flash something? or will it stick once i sucsesfully flash it?

will report if it works in a few seconds

edit: noobness showed there. haha thats a script to reinstall recovery at boot so once i delete it it wont reflash stock recovery right?

edit edit: nope, im not on linux (yet) my computer is a mess of three harddrives and messed up registrys and unofficial windows 7 haha. once i buy a copy of windows 7 its a full wipe and partitioning for a windows/linux dualboot

EDIT EDIT EDIT: SUCCESS now i flash linux's kernel :)

Thanks for the help you guys. once i get some money from the boss man i will gladly donate a little something something for the cause
[Acer Iconia Tab A100] pio_masaki:
Once that's removed or renamed it will stop, one time deal.

[Acer Iconia Tab A100] linuxsociety:
Also I noticed you mentioning that you are using a stock rom, you might want to talk to pio_masaki about this; but to my understanding the stock roms from Acer are not suppose to be flashed from custom recovery. I have read different things on this, however I haven't ever attempted to do such, from what I can tell doing this can or will brick your tablet by overwriting your bootloader and failing to install android, giving you no way to get to recovery nor android.. Might be something you want to discuss with him sometime.
[Acer Iconia Tab A100] pio_masaki:
In your kernel thread he mentioned staying on stock for stability, so I don't think he'll be flashing off stock anyways. Not yet anyways....

Restoring stock works as it leaves the boot loader alone.

[Acer Iconia Tab A100] linuxsociety:
Thanks, just trying to look out for these newcomers - however I'm still a bit confused at which causes the brick. The way I first interpreted it, it was flashing any Acer packaged update.zip from a custom recovery that would cause it. Then someone said that only the HC zips would. So to play it safe, I believe I'd double double check as many times as possible before I flashed any .zip from Acer from either twrp or cwm if it was me. Wish there was some clarity though on which Acer zips are SAFE and which ones are BRICKs -n- a Zip lol
[Acer Iconia Tab A100] pio_masaki:
The ics Acer zips are known brickers but it happens for a reason I'm not very clear on. HC will also brick it.

Basically there's a chance it will run the zip, attempt to flash everything, however for some reason it will fail to flash system or boot correctly, but does replace the bootloader. What I'm not clear on is why it fails on system or boot but succeeds on bootloader, or why recovery doesn't error flashing it.

Once this situation occurs you get locked out of both recovery and system by the bootloader, no adb or fastboot access to correct it.

Using the information I've gathered on this I've been working on a method to restore to stock if needed, but its going slow as I have to triple check everything before I even test it. Its a long and annoying process but should result in a 100% factory stock system.

Great Francis88, mind I ask which method of installation you chose?
[Acer Iconia Tab A100] ilyuha1108:

[Acer Iconia Tab A100] pio_masaki:
I'm not sure if that's just coincidence or really just an ICS kernel issue, or just a time based thing where not enough /cache wipes were done to trigger it, or any number of things could be attributed to why it hasn't been reported in HC vs ICS and JB. It could very easily be that flag causing it as it started showing up and causing problems in ICS for both us and Samsung users, however iirc a kf bricked on stock which is GB. Even if that flag isn't causing it, its still a step taken to help prevent it, just in case it is the trigger for it.

Honestly its a hardware fault, the kernel may trigger it, but its still a firmware issue that needs patched and Acer needs to wake up and work with us like Samsung did once it was discovered.

Tapatalked from my A100 - Kuroikaze B3
[Acer Iconia Tab A100] linuxsociety:
Very well put pio_masaki ! The kernel isn't at fault entirely, but the kernel may be executing functions as it is suppose to when certain hardware reacts a certain way, disabling the mmc_cap_erase function in the kernel and in userspace only leaves one way for the hardware to fail - in the hardware only. If an hardware event is triggering something from userspace or the kernel that isn't there, then it simply can't happen.. And when I say this I don't mean that the brick can't happen, I mean if this is the order of events, then it can't happen.

Then there is the possibility that this is happening from different causes, but resulting in the exact same result. Taking the precaution definitely helps eliminate the chances of it happening. So lets say that ICS makes a call to the kernel that HC does not, even though the kernels are practically the same in HC and ICS, this wouldn't happen with HC because userspace never makes the call that causes the kernel to execute the MMC_CAP_ERASE function, adding the protection at the kernel level doesn't mean that the kernel has been the blame, it just helps the kernel to protect your hardware from a userspace call, as well as from a kernel reaction to hardware events.

Not mount sdcard ext.

[Acer Iconia Tab A100] linuxsociety:
**Edit: Francis88 Sorry for the small error regarding sd-ext, this should now be fixed, all download links in the OP have been updated with new recovery.img Please update, this also includes some updates pushed to the main TWRP sources regarding onscreen keyboard, and an issue when trying to mount ext3 partitions as ext4.

Everyone else who uses sd-ext please download the updated files in the OP and reflash. Sorry for the inconvenience, I try hard to get these things corrected ASAP.
[Acer Iconia Tab A100] Fransis88:
Now if it works perfect, and many thanks for the work and quickly! The new aesthetic also i like more, in addition to the touch that looks more pleasing to the eye.
[Acer Iconia Tab A100] linuxsociety:
Francis88 this really was at fault of my own, for simply overlooking the sd-ext partition type. SD-ext really isn't common these days and easy to overlook on a device such as the a100. Especially since we have 5+ GB of ext4 storage at /data/media - Do you have so many apps that you need sd-ext on external sd? I'm just curious as to why you are still using sd-ext in the first place. Old sd card from one of your first phones that had limited internal storage?

The interface isn't new either, its just the other version of TWRP you had used was made with personalized images / backgrounds etc for the GUI that appeared to be smaller in size. The native resolution of our device is 1024x600 and that's the GUI layout that is used from TWRP, so that it looks like it is suppose to, however some folks may like the smaller sized images as it does make the fonts look a tad cleaner but the interface less precise at touch location. All in all this is mostly a vanilla TWRP build for our device using the native TWRP gui layout at 1024x600, default mount points, and slimmed down non-overclocked version of my a100 custom kernel. Nothing special added, nothing extra, just TWRP the way it is suppose to be :)

Also I have tested apps that use Open Recovery such as Goo.IM's Goo Manager and it works great with this, just be sure you set your storage path to /data/media in Goo Manager and when you get a Gapps update or ROM update it will notify you and flash it for you with twrp automatically. If you have the roms on external storage though you will need to implement a few changes in your userspace to get it to work with twrp, basically all you need to do is create a symbolic link from /mnt/external_sd (or /storage/sdcard1 )to /emmc and set the path in Goo Manager to /emmc, you'd need to do this via init script at boot, so that it creates the /emmc directory as a symlink, otherwise the settings will be lost after reboot each time. I think it may be easier to just use /data/media for Goo Manager + TWRP compatibility, or you also have the choice of just temporarily copying your roms to /data/media each time before flashing with Goo.
[Acer Iconia Tab A100] Romman0:
Updated fine with the zip, from 2.1.1.

One thing I'm seeing is all my backups including the one I just made (with this new version), are not showing an option to restore the recovery. The recovery is showing up in the backup file, just not in the restore window.
[Acer Iconia Tab A100] linuxsociety:
I think this feature is intentional not a bug. This is to prevent people who blindly restore/create backups from downgrading their recovery, or accidentally flashing back the wrong recovery when they restore. I will check into it more, but I don't think its a problem - like I said I think it is most likely a safety feature to prevent people from flashing a different recovery on accident.
[Acer Iconia Tab A100] linuxsociety:
Yes your previous TWRP backups should be 100% compatible with this release.
[Acer Iconia Tab A100] Tx Redneck:
Thanks for the auto installer script(s), but I seem to have an issue. After running the script and pushing twrp, when it or I try to reboot to recovery, it just sits at this screen. How should I proceed?

EDIT: I re-read the thread and saw the post about the stock recovery script and renamed it, reran the tool and it worked as expected this time.

Thank you sir for the fine work!

What is GPU frequency on the latest kernel? You wrote there was a gpu overclock but i couldn't notice any increase.
[Acer Iconia Tab A100] linuxsociety:
This is the wrong place for that question. But to answer the question, i just updated the items listed under features, as I didn't have GPU overclock listed previously. that is why you didn't notice an increase, because it was already there before. Please don't post my kernel related issues in threads that have absolutely nothing to do with the custom kernels

[Acer Iconia Tab A100] -DarkKnight-:
does someone have a CWM revert zip?

or just the recovery img? just in case something goes wrong i want to keep one on my tablet?
[Acer Iconia Tab A100] linuxsociety:
All you need is the original recovery.img for CWM if you wish to revert, you basically follow the same steps above, or you can edit one of my zips to include the cwm recovery.img instead. I don't think you should have any worries, this is the official open recovery for our A100 now.
[Acer Iconia Tab A100] Abu-7abash:
I can't for the life of me figure out how to USB mount either storage from this recovery. Anyone?
[Acer Iconia Tab A100] linuxsociety:
When I first configured this release of TWRP I may have omitted the USB Mount options as I honestly assumed it was for OTG USB support not for USB Host / Mass Storage. That's the only thing I can think of, but I would recommend you use adb push/pull to transfer files to and from the device via USB from your PC. This method works fine without the need to 'mount' the device.

If users actually need to be mounting their device in mass storage mode for some reason other than I am aware of, then I will make note of it when doing the next Open Recovery release.

If you mean that you are trying to get an external USB drive to mount, then it won't work as the a100 doesn't support OTG, however the A200/A500 devices do (which was the reason that I didn't include USB Mount support in TWRP on the A100 (documentation on recovery is very non-specific for devices, and there are no templates to go by when building, I was under the impression that host mode USB would work if TWRP supported it without needing to add the support for it manually as most all devices do include this capability. However if Mass Storage mode depends on a configuration option at build time, then this is why it isn't working for you. I will definitely check into it. There will be more builds in the future, in the meantime just use ADB mode like mentioned above to transfer files to and from your PC/Linux OS while booted into recovery.
[Acer Iconia Tab A100] Abu-7abash:
Yea I was talking about PC usb mount, I use that often snd it comes handy when stuck in a bootloop and have nothing on the sd. But alas, will be waiting for the next release :)

Thanks for your answer and all your work btw, this is great! :D
[Acer Iconia Tab A100] das_webos_transformer:
Or, mount your micro USB card, and flash from that, Mount it with, say, cell phone? Or anything else really, some people have an adapter... I've seen them, I really want one!
[Acer Iconia Tab A100] Abu-7abash:
I didn't say it was the only way to get out of a bootloop but rather that it will come in handy.

[Acer Iconia Tab A100] max69power:
if you are not too good with ADB or just want another way to access your files even root from your pc you can use android commander. It gives you a windows explorer feel. I still encourage the use and learning how to use adb but some times it is nice to see the file structure in a different way. Best of all it is free you can search xda for the good link to it.

Hi, i used link for my recovery.

I read that this OP has taken steps to prevent brick device, can i update using the link provided 2 top above me.
[Acer Iconia Tab A100] nsmith4:
Yes you can use one of the zips from that link, that's what I used. The steps taken for preventing a brick don't seem to work on our device (from what I understand they were steps adopted from another device to help). Unfortunately bricks still seem to happen even with these precautions.
[Acer Iconia Tab A100] rain987:
Sorry to be off topic, just one more question,

i tried reading the brick thread, but unable to find what i was looking for.

From what i read i gather that brick happens 'randomly',

1. is there any thing i should avoid to prevent any brick.

2. what do u know that would be the cause of it
[Acer Iconia Tab A100] Romman0:
Like nsmith said all you have to flash the 2.2.2.1 upgrade zip with twrp and it will work.

I don't think there is anything you can do to definitely stop the brick. But I dont think anybody has bricked while on cm10, but I could be wrong. So I would just stay on cm10 with twrp.

hi from spain and sorry for my english, i readed the thread but not find solution, i installed the automated version and after rebootr appears the android robot with the triangle, i don´t know if it´s installed well or not, and how i can enter to cwm for install a moded rom?

sorry i came from a s3 and it´s more easy.

Thanks again
[Acer Iconia Tab A100] pio_masaki:
Cwm is replaced by twrp, its one or the other.

Make sure /system/etc/install-recovery.sh is removed or renamed to install-recovery.sh

After that install twrp again.
[Acer Iconia Tab A100] john_smith:
ok, at end i installed it but not necesary this, it was the acer was loocked, after unlock i install it.

but i try to use a script for changes the sd internal by external , for more space, it´s with the file install-recovery.sh at etc but not run.

any idea how i can do the same?

thanks
[Acer Iconia Tab A100] pio_masaki:
That only works for stock roms, if you run a cyanogenmod ROM you'll need a script manager to run it.

Hello everybody

I can't install recovery in any of this ways (my a100 is rooted and unlocked), I tried with:

1) goo manager -> says there is no recovery for my tablet (???)

2) linux installer (ubuntu 32bit) -> stuck on fastboot first line, saying something about waiting usb

3) linux manual installation (ubuntu 32bit) -> same

4) windows installer (win8 both 32bit and 64bit) -> does not recognise adb (maybe i need to install adb manually, is it possible in win8?)

5) installation from link http://xdaforums.com/showthread.php?t=1608152 -> same problem with adb

any suggestion? how can i do?
[Acer Iconia Tab A100] pio_masaki:
You're not setup for fastboot, do you have any custom recovery installed yet?

After that i absolutely wanted to know whether the most recent version works.

So I allso installed now via "install open recovery script" in goo manager, the latest twrp ver-2.5.0.0-a100.img and it worked.

I got 2.5.0.0 installed on my A100. I'll test flashing tonight and let you folks know how well it works.
[Acer Iconia Tab A100] TheLoonyRebel:
My results so far with 2.5.0.0:

Backed up my current ROM (CMFLEX 1.3). Went smoothly. Rebooted and getting "root permission seems to be lost" error despite root being intact and working fine on my new CMFLEX 1.3 install. I know this same issue prompted up when the Note 2 (Verizon i605) went to 2.5.x.x but thankfully its been fixed. Can't remember off hand how it was fixed but I'll try to see if I can find out how it was fixed on that device so I can pass it along.

Other then that 2.5.0.0 is running great on my end here. ROM install worked completely fine including the AURORA based apps installer for CMFLEX 1.3. The new and easier way to wipe is a nice time saver.

By the way for those wondering I grabbed 2.5.0.0 with the GooManager app. I then had to manually install it from there using ADB. Pretty easy stuff even for a guy like me. :)

File name on GooManager is openrecovery-twrp-2.5.0.0-a100.img if that helps any! Good luck! Maybe the main post could be updated or a new thread could be started with info on 2.5.0.0 to make it easier for folks to find it?
