Acer a3-a10

Hello guys excuse my english

i have acer A3-A10 received OTA update, and now stuck in a bootloop, i need your help please. its not rooted, fully stock.

what i tried so far :

1- Wipe/Factory reset via stock recovery. still bootlooping.

2- I notice its a MTK65xx device,contacted xda member firediamond ( thank u alot for ur help )and tried to flash it via flashtool .it flashes red then nothing ,getting an error." SBrom_download_DA_fail (2004)

From the common hints and help, this error is due to loss connectivity between pc and the tablet, same error when i press firmware-> upgrade and for write memory.

3. Drivers are installed Correctly i can see VCOM ,tried both windows 7 and windows 8.1(with driver signature disabled ).

4. Removed back cover,,and removed the battery, and tried with flashtool same error, the pc detects the tablet as vcom for like 3 seconds and disconnects then it vibrates.

5. tried different volume key combinations, with power,, and insert cable still.

6. i used different flashtools all same ,SP_Flash_Tool_5.1343.01 and SP Flash Tool v3.1344.0.212

i believe the error is true due to loss connectivity, cause the tablet not maintain the mode for flash via flashtool i think its called META MODE , if am not wrong.

anyway to force it to stay in this mode, so can flashtool do it work ? i read about testpoints ? anyhelp please ?

Hello everyone, I have acer a1-810 with kitkat, which image do I use in order to get root?

I am sorry for my noobiness xD
[Miscellaneous Android Development] Optimissimus99:
At the Moment, its easyer to unlock bootloader for 810, for that look for The unlock thread (link was posted some posts before) than flash SuperSu 2.02 via Clockworkmod recovery
[Miscellaneous Android Development] Shreps:
Hi,

You have a bad version of SPFlash Tool

Use this one : http://acer.shreps.fr/dls/storage/A3-A10/SPFT-A3-A10.zip

To proper flash, try to unplug your battery, flash without battery, and then re-plug your battery, charge it for 10min.

Try and let us know ;)

Toolkit script enhancement request KK A1-810 w.r.t. "the wrapper"

[MENTION=3392632]entonjackson[/MENTION] : As [MENTION=2109242]twu2[/MENTION]'s workaround for mounting /system does not work on KK A1-810, could it be possible to modify your toolkit for A1-810 KK to conditionally not expand the su tgz, but have the su plainly copied over, just like it is done in your toolkit for all other Iconias? The only change is to additionally supply a plain su in the a1 folder, and in the script on the "kitkat" and "a1" combination just behave like (for example) the b1, but leave the old code in for non-KK A1-810's. As soon as [MENTION=2109242]twu2[/MENTION] has looked at the KK sources, whenever they come on stream, and built his runtime module (shared lib/object) to get the /system rw/ro-remount working again (for A1-810 KK that is) you could put in that solution, maybe with a Android app-like front-end (again, this would be possibly supplied by [MENTION=2109242]twu2[/MENTION]).

I will try your toolkit-tool for my KK A1-810, but I will modify the script, extract the su and so get the thing set up without the wrapper.
[Miscellaneous Android Development] Calingo:
The problem why we are unable to obtain rw system is because of the boot.IMG with a security patch if someone can mod the the boot.IMG he can obtain rw on system :cool:
[Miscellaneous Android Development] Just_Another_N00b:
I know, but because of that the toolkit for KK A1 and some B1 will not need the wrapper, as that is not working in KK. twu2 was looking into it (in the other thread) but without success for now. We need the KK sources for that..

[MENTION=3392632]entonjackson[/MENTION]'s code needs the following enhancements

1. add plain su in the a1 directory

2. modify code to this:

# add su binary
if a1 and not kitkat:
if debug:
subprocess.call("sudo tar -C /media/iconia -xzvf bin/a1/a1su.tgz", shell=True)
else:
subprocess.call("sudo tar -C /media/iconia -xzvf bin/a1/a1su.tgz", stdout=dev_null, shell=True)
else:
if debug:
subprocess.call("sudo cp " + su + " /media/iconia/bin", shell=True)
else:
subprocess.call("sudo cp " + su + " /media/iconia/bin", stdout=dev_null, shell=True)
[Miscellaneous Android Development] Calingo:
KK Sources

Yes acer has agreed to post sources to acer devils in 2 weeks :cool::cowboy:

Hope they keep their promise
[Miscellaneous Android Development] entonjackson:
Of course I could do that. I already have seperate code for each versions.

What su binary do i need instead? Maybe PM me for this.
[Miscellaneous Android Development] Just_Another_N00b:
Just the standard su (out of the tgz file?). At some moment, for the remount, we might need su in other locations as well (like xbin and add some startup fix, but I have no detailed knowledge on that - for now). There is another thread on this rooting KK A1-810 (http://xdaforums.com/general/help/acer-iconia-a1-810-rooted-suid-t2849308), but that part is not yet at a stage of working full 100%.

This part only relates to the root-from-scratch on UN*X, as the 'from image' already has gone past that...
[Miscellaneous Android Development] entonjackson:
v0.8.5

======

- A1-810: Fixed target directory for system image (no permissions for /cache directory since Kitkat)

- A1-810: Fixed root from scratch for Kitkat versions (thanks to Just_Another_N00b)

[Miscellaneous Android Development] 97pedrocas:
Yes!!

I have root and CWM on mine, thanks everyone!

You guys think there will be any costum roms for this tablet?
[Miscellaneous Android Development] y2k-inc:
But is the system can be writable with the toolkit (root)?
[Miscellaneous Android Development] Just_Another_N00b:
Sorry, no, not yet for KitKat (4.4.x). People are looking into this, and as soon as we have the KK source code for the A1/B1 available would we be able to fix this. The work-around (wrapper.sh symlinked to mount in bin) is only working on JB (4.2.2), so please be patient. A solution will come ("soon?").
[Miscellaneous Android Development] y2k-inc:
Thanks, i was hoping with the root from scratch you can get around the wait for Acer source code :)

Can rootear the B1-730HD with kiktakt 4.4.2?

you'd need files and upload?:confused:
[Miscellaneous Android Development] Just_Another_N00b:
This toolkit does not work for the B1-730HD, as that tablet has an Intel Chip inside. The toolkit is meant for MTK processors...

Having the same issue, is there any solution? Please! :fingers-crossed:
[Miscellaneous Android Development] Just_Another_N00b:
Some fixes

[MENTION=3392632]entonjackson[/MENTION]: When trying to pull an image with your latest kit (0.8.5) I was not able to do that on my A1-810 KitKat. The reason was that the whole 'Spiel' with respect to KitKat on the A1 was not set up when just pulling the system image. I also noticed that under the unix_root_from_scratch nothing was set up for starting the telnet server in KitKat mode. Below is my debug output, and I also supply here an amended .toolkit.py (diff report html and patch-file) which prompts for the KitKat question in the main menu, so as not to duplicate the questioning everywhere. Hope this helps you make the product even sturdier. I will try the enhanced script, as the current one only gave me an empty image. tgz-file was 20 bytes.

As the KitKat thing was not recognised by the system pull, it tried to use /cache. Not working... By just changing that (see debug output) I got to the empty system image. But that is purely related to the non-KitKat handling when pulling...

-- Edit --

I have tested the modified script. Now I do get the A1-810 KK MTK Logger, but still the telnet server either does not start up correctly, or dies underway while pulling the system image. I will modify the first telnet session to allow debugging there too.

Another thing: The toolkit.sh was missing a "$*" parameter-passing, so that toolkit.sh -d was not recognised... Attached second Log and modified toolkit.sh.

Hey, so sorry if this has been answered or addressed. I've skimmed through the posts and wasn't able to find anything but I may have missed it. I am trying to root my A1-810 with the latest 8.5 toolkit, but when it goes to run the command I end up getting the error:

From Linux or Windows - no difference.

Mediatek Network utility started ok, but telnet server can't start (RUN button not active).

what could be the problem?
[Miscellaneous Android Development] gansolc:
CWM-recovery work a1-810

1. Launch SP Flash Tool ("/SPFT/flash_tool.exe") as Administrator.

2 Press "File" -> "Open Scatter-loading file..." and choose file “***_emmc.txt” in “1srt step” folder instead of “810 Unlock and CWM” folder

3 Only check SEC_RO

4. Press "Download" and connect turned-off tablet to PC

5. Progress bar will fill with red, then with yellow, then you will see green circle.

6. Restart Tablet, switch off

7. Press "File" -> "Open Scatter-loading file..." and choose file “***_emmc.txt” in “2nd step” folder instead of “810 Unlock and CWM” folder

[Miscellaneous Android Development] Optimissimus99:
Hmm, network utility is onlay for JB, for KitKat it should open "MTKLogger", if not there is something wrong with the Toolkit
[Miscellaneous Android Development] gansolc:
root works a1-810

not 100%..only mount r/w not works :(
[Miscellaneous Android Development] theNebula:
But 0.8.5 try run exactly Network utility, not MTKlogger... How I can start MTK logger manualy?
[Miscellaneous Android Development] Just_Another_N00b:
There is something wrong with the toolkit for KitKat versions. By default the current code will not always start the MTK Logger, because the kitkat variable is not always set. But even then I have had the telnet daemon refuse connection at some stage. Still not sure what the problem is, looking into it with some extra debug statements here and there. But visually you only see the MTK Logger screen on the Iconia, and nothing happening there... So I am still trying to get the thing debugged and find out what is happening... Wil keep you posted.

[Miscellaneous Android Development] Just_Another_N00b:
This is one of the current flaws of the script. The /cache location is not working for KitKat. The script not always sets the KitKat flag, and only in some cases uses the correct temp location. I am trying to find out what more is needed to get it all working, but this part is not too hard to change. I myself have some issues getting the telnet daemon to stay alive on my A1-810 KitKat...

I think [MENTION=3392632]entonjackson[/MENTION] should look at the code (the stuff I supplied is only part of the solution, methinks), but we could all try to help out where we can. KitKat is a bit of a nasty boy for this toolkit.

0.8.5 Toolkit A1_810_RV0BRC01_WWGEN1 ROOT FAIL

Hi

SUCCESS!
Your Acer Iconia A1-810 / A1-811 / B1-711 / B1-720 is now rooted. Unplug your tablet and reboot. Install Superuser from the Google Play Store and have fun ;)
If your tablet is turned off and doesn't turn on anymore, take a pin and press the reset button on the right side of the Iconia B1, above the power button....

file su present in /system/bin

Install Superuser fro Google paly - root not detected

Install SuperSU - it can't install binary.

Do i need install SuperSU from CWM?

Please, help me.

PS

I flashed su from a1 folder

---------- Post added at 03:05 PM ---------- Previous post was at 03:00 PM ----------

Hi

0.8.5 script for A810 Kitkat has 3 issuses:

1. var kitkat is set False but must be True

2. var system_image_target_dir set to /cache but must be set to /data/local/tmp

3. var su is not set
[Miscellaneous Android Development] Shreps:
I think the best way to root on KK is

- Unlock your bootloader

- Flash CWM

- Flash the SuperSu zip :)
[Miscellaneous Android Development] Just_Another_N00b:
[MENTION=3392632]entonjackson[/MENTION]'s script is open source'. I like that better than a bootloader I cannot examine... Personal choice, I know...
[Miscellaneous Android Development] entonjackson:
The only error I see, is that su binary is not set properly.

For the other two points see .toolkit.py line 667 and 669. They are set.

I fixed setting the su binary. Could you please try this version and give me feedback?
[Miscellaneous Android Development] Just_Another_N00b:
Unable to make it. But still working on it. My version of .toolkit.py script is attached, together with latest Error log... This script sets KitKat right and at the start of the script. No additional questions needed...

-Edit-

I added the diffs-report between your latest version of today and the latest I have (with the telnet server checking in debug mode added, which dies).
[Miscellaneous Android Development] entonjackson:
i don't see a difference, to be honest...

could you please try my version also? just to make sure.
[Miscellaneous Android Development] Just_Another_N00b:
I moved the query for KitKat to the main part, so that the kitkat variable and temp location (not cache) is set rightaway for KitKat. Look at the diff-report html file (in toolkit-diffs2.zip) to see what changed in the .toolkit.py script. I took your script from today to compare to. This is only to make sure the kitkat logical is set for all options. I myself am trying to debug to see whether I can extract the /system partition (needed also for the rooting from scratch process, and I want to test if the telnet server is started).

What I could do is make an extract of the code purely to see if A1-810 KK extract works with MTK Logger (there is no visual feedback on whether commands are accepted in the MTK Logger screen). But the check on telnetd being alive crashes as seen in my last log.

Question: why do you use shell input keyevent KEYCODE_SPACE to stuff a space instead of the %s method for getting a soft space into the input. Would that generate different spaces for the other side...
[Miscellaneous Android Development] entonjackson:
So. does my code set the variables or not?

What i like about your changes is the debug stuff. I think i could merge that.

What i don't like is the code that i commented out. I did that for a good reason. I don't think that has ever worked.
