Acer Iconia A1-810

Hello sir. I am having a problem on rooting my a1-810. it says, failed to copy system_img.gz something like that. i followed your steps. and im using the latest toolkit. please help me with this.

Thanks for your future reply :D
[Miscellaneous Android Development] entonjackson:
i need all the output.
[Miscellaneous Android Development] RikudouSennin:
here sir :)
[Miscellaneous Android Development] konsolen:
hi, with this little informations, i would say you dont put an image to the image folder or you did not start as Administrator.

Point 1: put a system Image in the correct folder

Point 2: shift + right click on mouse to run as admin
[Miscellaneous Android Development] RikudouSennin:
Hello sir. Thanks for yourr reply. But already did all the requirements.I ran it as Administrator too. I put the image @ system_img FOLDER :)
[Miscellaneous Android Development] entonjackson:
is the system.img.gz really there? no system.img.

is there enough space on your device?
[Miscellaneous Android Development] RikudouSennin:
I have 8gig free of memory on my Acer IConia a1-810

and yes. the system.img.gz is in the folder
[Miscellaneous Android Development] entonjackson:
Try to start telnet server manually then try again. How to you can find in the FAQ.
[Miscellaneous Android Development] fnldstntn:
Factory data reset may help you... i had the same problem and that solve my problem...
[Miscellaneous Android Development] RikudouSennin:
Thanks to all of you :D Im gonna try all of your suggestions. Thanks a lot guys :D
[Miscellaneous Android Development] RikudouSennin:
I am having a problem sir? After i successfully rooted it on the toolkit, thanks to your suggestion , I installed SuperSU.. But superSU said that there is no SU Binary installed. SuperSU can't installed it. Please help me :(
[Miscellaneous Android Development] fnldstntn:
Your tablet is not rooted... Maybe you used wrong pre-rooten img..
[Miscellaneous Android Development] RikudouSennin:
aww. i downloaded and used the one with with the name "system.img.gz under RV27RC03_WW_GEN1 of Acer Iconia a1-810. Maybe the other one should i download? Tss. Thanks for the hint sir. I'll download the other img named, stock.system.img.gz.. i have aquestion sir, should i download the update.zip too and flash it ? I did not download it. coz i dont know whats the use of it. there's no instruction. :D
[Miscellaneous Android Development] konsolen:
I hope you know what you are doing.

Why you need root for your device? Dont understand me wrong, but these steps are very good described and the tool make all without compex inputs.

And when you are put tje wrong systeimage inside the folder, your Tab will brick.

Please read carefully the first page of this thread and it will work.

Do you have the correct adb drivers installed?

To download the correct image is the only thing you must do normaly. The rest do this toolkit.

Is there a way to install Xposed Framework 2.6.x on A1-810(Rooted with 0.8.1)At the Moment i have a modded 2.4.1 installed (found somewhere in the Internet)
[Miscellaneous Android Development] entonjackson:
Yes but beware of what you change. Changing DPI for example will brick your device.
[Miscellaneous Android Development] Optimissimus99:
Sure, thats not the problem. But the version from xposed repo doesnt install the files to system. I will try to decompile it and change mounting scripts ;)

Edit: OK, the newer Versions dont have scripts for Installation, just Java code. and i'm not good in Java development. But i saw that it has an included busybox file. now we just have to find the links to it, and replace it with the System busybox ;)
[Miscellaneous Android Development] fREAST:
Oh and why decompile it when its opensource?

https://github.com/rovo89/XposedInstaller/

In short what the XposedInstaller do is:

Makes a backup of the exsisting /system/bin/app_process

Copies the modded one from /data/data/de.robv.android.xposed.installer/bin/app_process to /system/bin/app_process

Changes permissions on it;

chown 0:2000 /system/bin/app_process

chmod 0755 /system/bin/app_process

All this can probably be done manually with say Root Explorer, or possibly with a terminal, since you have to mount /system as writeable.

Edit: And the app links to its own busybox here.

[Miscellaneous Android Development] :
Anyone tried this new root method? - http://www.xda-developers.com/android/breaking-geohot-roots-the-verizon-galaxy-s5-with-towelroot/

I'm really tempted to see if it'll work on our device.

EDIT: Doesn't work on B1-710, tried v1 & v2, no positive result.
[Miscellaneous Android Development] fnldstntn:
A1-810 does not work...
[Miscellaneous Android Development] Optimissimus99:
But 810 should work with the toolkit, also with latest Version. Just the 811er makes trouble
[Miscellaneous Android Development] :
Ah well, B1 might be same then, tried it on my Galaxy Tab 3 8.0 just for kicks & it didn't work either, not that it's hard to root it but anything that can root a device without using additional tools/recoveries an a PC begs to be tried.
[Miscellaneous Android Development] redemption024:
Hi, guys. Got myself a b1-720 and as usual the first thing I did was lookup the root method when I got home. I regret that I haven't done my homework before picking up the device. I assumed every android out there can be easily rooted. My bad. Too spoiled I guess. My world is centered around the Nexus and Samsung devices :silly: can't be helped.

Anyway, I think I'm missing something here. I got the toolkit, and tried to root. It says I needed the prerooted sysimg? I looked and couldn't find it anywhere. So instead, I tried to pull the sysimg and that too failed. (just coz it didn't say I needed root to do it :p )

Hello! My English is bad, sorry. My post is related only for B1-A71 users.

I think I can find the way to unbrick our tabltets.

I have scatter file and testpoint found by me.

Notice: you need to install drivers attached to this post and turn on PC speakers.

To access the testpoint you need to turn off (no need if bricked) and remove the back cover of tablet. You can leave battery or disconnect it - no matter. You need to connect the battery- and testpoint (see picture). Then connect the tablet to PC. Tablet will be recognized as MTK USB Port (COMxx). After recognization disconnect tablet. Open SP Flash Tool (use exactly v3.1344), load scatter file (do not worry about MT6577 instead of MT8317 in the name - SPFT says about A71 have exactly MT6577 CPU) and prepared files. Then press download, connect A71 with tespoint and wait...

And here I need your help! I have not a ROM Backup! And in SPFT: after red progress bar filling and transfering 136680 bytes PC will make a Device disconnected device and when Device connected sound. Then ~1 second freeze. And then will be an error.

5007 ... NOT_LOADED_YET

I dont know what I need to do to fix that error.

Here are the files.

So I seem to be having no end of problems here. I decided to go ahead and try to root my device which is still running RV04RC04, but during the process I get the error: "Your device has 'android 0x0000000015e00000 0x00000000020e8000 2 /dev/block/mmcblk0p3' in dumchar_info. Continuing could brick your device!".

Seeing that this put Min Thura's device into a boot loop not too long ago, I am dubious to continue, as the only way to resolve a boot loop is by re-flashing, but of course I cannot do this due to the partition error!! :(

Could anyone offer me some guidance as how to proceed here, might it be worthwhile getting a replacement device from Acer? :)
[Miscellaneous Android Development] entonjackson:
with a system.img.gz from RV04RC04 you should be doing fine.
[Miscellaneous Android Development] agentdeep:
you think doing factory reset can enable updating without error?
[Miscellaneous Android Development] entonjackson:
No, I said, if he has RV04RC04 installed then he can root with system.img.gz from RV04RC04.
[Miscellaneous Android Development] DarrellW94:
Thanks for your quick reply! :)

Looking at a worst case scenario, if I did get stuck in a boot loop, how would I go about recovering from this when I get the partition error when flashing? :confused:
[Miscellaneous Android Development] entonjackson:
try to apply firmware update RV04RC04 first. if that fails I wouldn't root with system.img.gz.
[Miscellaneous Android Development] DarrellW94:
Thanks for your response again. Maybe I'm being a bit slow, but is there a download link for that firmware anywhere? :confused:
[Miscellaneous Android Development] zyche:
i have successfully updated from RV04RC04 to RV05RC05 using the sdcard.. i've been trying to root but i'm always stuck at the failed to copy system.img.gz which i've downloaded at the links at post #1.. where did i've failed to follow in the procedure?
[Miscellaneous Android Development] entonjackson:
you should have read the common issues on the 1st post also. especially the last question!
[Miscellaneous Android Development] zyche:
@ entonjackson

i have the right system image.gz in the folder system_image for RV05C05 yet it failed to recognized.

i have read your post#1 and follow again the procedure this time with toolkit.exe -d

"failed to copy system.img.gz"
[Miscellaneous Android Development] entonjackson:
Your telnet server is probably not started on your tablet. This can sometimes happen, as the process to start telnet server on tablet is a little bit fuzzy. Try to manually start telnet server make sure you're still in Networking Utility App and the following command is entered:

Then click on Run.

If it still doesn't work, post the output of -d here, otherwise i won't help you further!
[Miscellaneous Android Development] entonjackson:
1. i would try newest version v0.5.5

2. it seems there is no system.img.gz in system_folder obviously... are you sure the system.img.gz is in there and not system.img ??

3. start as administrator.
[Miscellaneous Android Development] entonjackson:
Have you also tried to start telnet server manually?
[Miscellaneous Android Development] zyche:
yes type it manually in the tablet..

i' think i have to rest for awhile.. and try it again later..

thanks a lot...
[Miscellaneous Android Development] entonjackson:
v0.5.6 is up.

Actually it should be v0.6.0 with deodex feature included, but i just don't get around how to deodex.

i tried to deodex with baksmali + smali first. but when trying to install it i get:

then i started zipaligning it after deodexing... fine, but the same error still occurs.

And yeah i googled around a lot and i think i need to sign it with jarsigner. but before i can do that, i need to create a private and or public key with keytool. wtf? it cannot be that hard to deodex, right? alright, so i tried to create a key. i think i got one, but the result was still the same.

so i did a jarsigner -verify onto my deodexed apk, then it complained about the classes.dex not being proper. for sure, i added it to the apk as a result of baksmali and smali... :eek: very confused. is this signing stuff not relevant for developing own apk's?

if someone has experience here, help would be really appreciated.

So here the changelog for v.0.5.6. Maybe the issue failing to push system.img.gz to /cache some users are experiencing here is fixed with this.

- fixed: permission errors for pulling/pushing system.img.gz from/to /cache

- more debugging output, less output without debug argument

- trying to start telnet server on tablet more secure

- root: checking if system.img.gz is available in folder system_image

- fixed: redundant prompting to unlock tablet for starting server

Update or not.

Hello friends, buy this magnificent tablet yesterday and I have the version RV04RC04 and wanted to know if I upgrade to the RV05RC06 advise or stay in which I have.

To update RV05RC05 I install first and then install directly RV05RC06 or RV05RC06

I would also like to know if I have to root to do something manual or the program takes care of everything.

I would appreciate your response.
[Miscellaneous Android Development] Eduardogv:
Hey this is a great tool congrats man :D

How about including tablet UI into this tool? I´ve been searching about how to force tablet UI ( with the nav bar and the notif bar in the bottom, not divided like in our B1) anyway I´ve tried changing the DPI, but with no succes. Changing the DPI only get System UI FC and everything looks smaller and the status bar or nav bar doesnt appear.It doesnt work

So I´ve found this thread http://xdaforums.com/showthread.php?t=1780970 . It´s very clear and short it explains how the PhoneWindowManager.java select the UI to present in display . It was written thinking on the N7 running 4.1 but what is important is the info :D

With tablet UI we could gain more space in the diaplay by dissapearing the status bar and putting the nav bar in the left bottom side of the screen. Havent you thonk that having the nav bar in the middle is sometimes annoying and not so useul? It difficulties the manipulation of the tablet with one hand and at least for me its not the optimal UI for a tablet.

Could you please take a look at this and try to include it? It would be awesome. Thanks

Hi, I did a little test with testpoint and spflashtool, EMMC was not initially found but then I managed to format the entire EMMC and flash all my backups except preloader, if flash preloader before I can not flash the rest, any ideas?
[Miscellaneous Android Development] Moriveon:
So I did many tests and here is the result:

As I have not DSP_BL, I tried to flash boot.img (got it from update.zip)

I pressed Download, connected testpoint and USB cable, the in SPFT, red progress bar has appeared.

If you will disconnect testpoint, you will get

BROM ERROR: S_DL_GET_DRAM_SETTING_FAIL (5054)

[EMI] Obtain DRAM failed!

And if you will keep testpoint connected you will get

BROM ERROR: S_DA_EMMC_FLASH_NOT_FOUND (3144)

Any solutions to fix that without formatting?
[Miscellaneous Android Development] drmad:
I did many tests too on my b1-710,

1. format whole emmc ... OK

2. flash all blocks except preloader and dsp_bl ... OK

3. flash preloader and dsp_bl ... OK

RESULT: no vital signs, no charge batt, no turn on, pc recognize preloader and connect and disconnect continuously

Locked Bootloader maybe?

This was happening to me as well when I tried to use SPFlash Tool and then some one said that its because of locked bootloader?
[Miscellaneous Android Development] Moriveon:

System RW Workaround

I rooted my tablet A1-810 with a version that didn't include the System R/W Workaround. Since I'm already rooted I can't use the toolkit right? What do I do to get System RW permissions?
[Miscellaneous Android Development] OlivierS:
Rooted A1-810 with Toolkit but SuperSu says no su binaries

Hello!

I have just rooted my A1-810 with the toolkit. I followed the steps, creating and extracting system.img.gs and moving it to the system-image folder of the toolkit then running the root option. All went well, ending with a success message telling me to unplug, reboot and install superuser from the Play Store.

I installed SuperSu first and ran it. SuperSu told me there were no su binaries.

I then installed superuser from ClockworkMod and ran it. I was then told su needed updating and offered two methods: Recovery Install and Install. I tried 'Install' first. Was told "There was an error installing Superuser. Please send a log of the error to the developer. Then I was shown a box saying "No Logs". Same thing using the "Recovery Install" option.

Frustratingly there seems to be a message box displayed just before the message I can read, But I never see it as it is overwritten by the most recent message.

Is there a permissions problem of some kind?

Thanks in advance for any help.

You may have root already..?? test with root checker or titanium backup and see..
[Miscellaneous Android Development] OlivierS:
Root Checker says: "Sorry! The device does not have proper root access."
[Miscellaneous Android Development] treetop777:
Reading your post again it says you "created and extracted the image" - was that (image) what you used to root? if so, you should have used a pre-rooted image. Better yet, "root from scratch" using Linux.
[Miscellaneous Android Development] OlivierS:
Haha! I must look so stupid! Not knowing what the toolkit did exactly I assumed that it patched the system image it was given! So obviously it's not the case and having done what I did perfectly explains why I ended up with a tablet on which I did not have the su binaries since it was not rooted. The message from the toolkit fooled me by telling me it was rooted: what it was really saying is that it had installed the image I had given it...

Now I have looked in "About tablet" and found my image is RV27RC03_WW_GEN1 and seen there was such an image in the first post of this thread so I am downloading this and will use it.

Is the "stock system.img.gz" the unrooted image which should be the same as the one I extracted from my tablet? What is the update.zip file? Chrome tells me it's malicious and it won't download it.

Thank you so much for putting me on the right track.
[Miscellaneous Android Development] treetop777:
Good deal! Yes, the stock image.img.gz should be the same as the one you extracted. Update.zip is not a virus, you use it with the stock recovery; download it with IE or something, just in case.

Enjoy.

Hello friend, I have a big problem, you procedure sounds really good and everything,but I can't install the Iconia B1 tablet drivers on my Laptop,because it has a bootloop,and the installer needs that my tab is connected,¿Can you help me? (I'm Costarican,excuse my bad grammar)
[Miscellaneous Android Development] Moriveon:
Does anybody tried to flash B1-A71 with testpoint?

I figured out that you are don't need to flash preloader (dsp_bl and other stuff ok) or device will be bricked forever and there is no way to revive it, even with testpoint!
[Miscellaneous Android Development] OlivierS:
Thank you very much. I suppose people like me shouldn't be allowed to do this kind of things. I resisted quite a few months, though!

But curiosity kills the fun...

Exploring the system recovery menu to get familiarity I chose Demo Mode to see how they sell it. Yes, that was not advisable, but there was no warning. As you probably know, once in Demo Mode always in Demo Mode until a factory reset (which makes sense for its intended purpose as a demo tablet in a shop). Another answer I found was to go into Settings|Storage|Internal Storage|Apps(app data & media content) and disable the demo from there. It also said the "Demo Mode" indicator on the screen may be left.

Well, yes it is left and that's annoying but even more annoying is the following greyed out settings:

. Display|Sleep set to 30 seconds (30 seconds!)

. Security - everything greyed out except for Clear Credentials

So I end up with a tablet that switches off after 30 seconds, where I can't change the security settings (understandable for a demo) and that proclaims at all times on the left of the navigation bar that it is in Demo Mode.

All that for wanting to see what the demo mode was!

(Of course) unrooting by using the toolkit to put back my old system.img.gz didn't change anything. And rooting again didn't either.

Is there a solution apart from factory reset or is there a possibility to back up all my data before the reset and restore it afterwards?
