my tablet is Acer Iconia A1-810 8GB im went backup my rom how i can ?

edit: how to Re flash stock rom ?
[Miscellaneous Android Development] andrewbat:
Toolkit = PERFECT

I just want to say to the developer - T H A N K Y O U

It rooted my Acer A1-810 perfectly through Linux.

I am one happy camper
[Miscellaneous Android Development] andrewbat:
Hi all,

Has anyone actually created a successful CWM to flash onto the A1-810 yet?
[Miscellaneous Android Development] bsdnix:
Hi Is anybody experiencing any issues with touchscreen. It looks like even after I clean glass screen with soft cleaning cloth, I get very lousy touch response. Are there any drivers or whatever that would "increase" touch ability?
[Miscellaneous Android Development] bigbob_ftw:
The boot loader is locked. Can't do anything as long as that is the case.
[Miscellaneous Android Development] andrewbat:
Thanks...

I guess then my question is has any one made any progress on unlocking the bootloader?
[Miscellaneous Android Development] drziddo:
Hello everyone and OP.

First of all thanks for this.

I bought an B1-710 to my 5 years old daughter as a birthday present, obviously first thing was try to root it.

The toolkit says it was succesful, but when I open superuser app it says Superuser binaries must be updated.

Try to update that but it gives me Installation failed.

I dont know what to do now.

Any help will be greatly appreciated.

Thanks in advance.

____________________________________________

EDIT:

My mistake.

I was trying to do it with SuperSU.

Original superuser app did the trick on this one.

My daughter is, obviously, very happy now.

Thanks again.
[Miscellaneous Android Development] andrewbat:
I suggest running the process again but through Linux and 'from scratch'
[Miscellaneous Android Development] tindean:
Quick question. The system image for the b1=710,, that's not for Canadian Model?

I need to have the PA_CA abbreviation?

Tried to use the one provided and got boot loop. All fixed now and want

To try again.

Will use Linux and his time. Windows told me successful root but bootloop

So I'm thinking I need a diff system image??

And yes. Acer had to fix bootloop , took them 10 min literally

Thanks for an answer about sys image.
[Miscellaneous Android Development] entonjackson:
Use Linux and provide us the rooted system.img.gz
[Miscellaneous Android Development] rajivshahi:
thank OP and everyone who made it possible.... You guys rock...:angel::angel::angel:
[Miscellaneous Android Development] tindean:
The image wouldn't be rooted that I pull, its back to stock now??

Unless I try to root it with the image from link in OP.,that will loop me again?

If I use Linux or not??

Do u want just my sys image unrooted, can I pull image without root on Linux?

Thanks
[Miscellaneous Android Development] entonjackson:
you can pull stock system image before rooting.

when you root from scratch under linux, after process finished the rooted system image will be in /cache on your tablet.

but you can pull the rooted system image after rooting also, with the toolkit.
[Miscellaneous Android Development] tfgu:
for a1-810 there was an update which fixed the problem.
[Miscellaneous Android Development] andrewbat:
Do you know where to find the update?
[Miscellaneous Android Development] tfgu:
if not in first post maybe acer update service?? I belive hide root is nessesery
[Miscellaneous Android Development] bsdnix:
I'm having B1-710 model, but mostly I need to touch twice so it recognize the command. I know that previous versions of android had touch sensitivity option, but on this particular version I haven't found that option...
[Miscellaneous Android Development] knak2k1:
Hi everybody,

I'm trying to root my Acer Iconia b1-711 but I have one question:

The toolkit tells me that the current firmware of my device is RV03RC03. Can I still root my device because the system.gz download in #1 post for b1-711 is RV01RC04?
[Miscellaneous Android Development] treetop777:
NO! you will brick it. If you don't see your exact firmware in the downloads, then root from scratch.
[Miscellaneous Android Development] knak2k1:
ok. and root from scratch via unix is 100% save? It cant brick?
[Miscellaneous Android Development] Just_Another_N00b:
Root from scratch is 100% safe. I did it from a live-CD (no install of Linux) of Ubuntu and it worked flawless. Use the script to first pull a non-rooted system image, if your version is not present in the first post, and pull another one after rooting. Make these available (google drive or similar) to EntonJackson to extend his set of images, he would like that.
[Miscellaneous Android Development] Thidney:
Hi friends,

I'm here because I need help to install a stock image on my Acer Iconia A1-810 tablet, I've been stucked in a bootloop, because I failed at rooting it.

I'm trying root with this thread. I did download my rooted FW (prerooted FW is RV27RC03_WW_GEN1) and tried root with Toolkit in Windows 7. I did everything according to the instructions, toolkit after root wrote "You have succesfully rooted yout device", so I restart my tablet and after I get bootloop...

For fix a bootloop I tried countless attempt.

A) I downloaded a stock image RV27RC03_WW_GEN1 and install with recovery mode (I tried install this stock image after rename to : 1) system.image.gz to update.zip; 2) system.image.gz to system.image.gz.zip;

3)I did decompress system.image.gz and file system.img compress to update.zip and second compress to system.zip ) so this four files I tried install by recovery mode, but each install gave me a error mesage "check.partition.size=[__PROP _UNDEFINED__]", and installation aborted.

I tried this with many WW_GEN stock image but only gave me error message.

B) After bootloop, I tried root/unroot with toolkit to stock image but tablet has problem with ADB conection (error message:"Trying to establish ADB Connection...

E: Couldn't connect to your Acer Iconia A1-810 / A1-811 over adb. Plug-In the device with USB-Debugging Mode turned on.")

But now, with bootloop tablet can't get to USB-Debugging mode.

C) I tried a root from scratch in Kubuntu, but remained the same problem as in the case B. Tablet has problem with ADB conn.

I beg you for help and I will be grateful for any advice.

Sorry for my bad english.

Thank you very much for some help.

Thidney
[Miscellaneous Android Development] treetop777:
There is nothing else you can do. Send it to Acer for repair. When you get it back, the success rate is higher using the toolkit in Linux.
[Miscellaneous Android Development] Wrightperspective:
I have the Acer A1-810 - I rooted this a while back and have hardly used the device. I am on the RV18RC10_PA_CA and was wondering the easiest way to unroot. Also, is there a newer version of Android currently available for this device?
[Miscellaneous Android Development] knak2k1:
hi folks,

another question:

I successfully rooted my iconia b711. Now there is a file called system.img.gz which is backup?

I accidentally removed some system Apps. Can I flash the backup back to the device? If so, how?
[Miscellaneous Android Development] entonjackson:
Where is this file?
[Miscellaneous Android Development] knak2k1:
Sorry, this file was created during the rooting process via the ToolKit (root from scratch). currently it is on my laptop.
[Miscellaneous Android Development] entonjackson:
where it came from?
[Miscellaneous Android Development] knak2k1:
from my device (iconia b711)

when I was rooting the device with root from scratch the first thing he did was to pull a system.img.gz (stock rom) from the iconia tablet to the local computer.

step 2 is the rooting process and at step 3 the toolkit pulled back the system.img.gz to the iconia tablet.

my question is, if I can flash these system.img.gz to my device because I accidentally deleted some system apps from my tablet with the app "root delete". these apps are gone forever. even if I do a system reset.

sorry for my bad english :)
[Miscellaneous Android Development] sapiii:
you have the 15e model?

I just plugged it in and tried the newest toolkit..... the first warning was:

"your device has 'android 0x000000000015e0000........................, continuing could brick your device"

Any suggestion what should i do?
[Miscellaneous Android Development] nick_1964:
Again thanks for all your work, I have sucessfully rooted 2 B1-A71 RV04RC04 now and one 05 ( I have 3 of this tablets, and a rooted samsung galaxy tab, a rooted Tomtec 8BT8 dual core and a rooted Advent Vega tablet and a rooted Bluestack emulator, plus 2 of those tv sticks thingy and a rooted android dual sim phone.. Google will warm me I think :p

---------- Post added at 01:15 PM ---------- Previous post was at 01:14 PM ----------

I have 2 , 15e models and I ignored al warnings, but again, it is ALWAYS at your own risk.
[Miscellaneous Android Development] Min Thura:
My Acer Iconia B1 goes into boot loop.. :( So, should I download latest firmware from acer website and install it from recovery ? Or should I download the same version in my B1 which is RV04RC04 ? Or what should I do ?? Plz help me... Thank you..
[Miscellaneous Android Development] entonjackson:
Right, it will probably not brick your device.

Noneoftheless the partition info on your device is faulty. I'm rooting your devices as if the partition info would be different.

But of course i can't and won't garuantee for 100% that your device won't be bricked, because then i would be the bad guy.

But i think for 90% your device will NOT be bricked. as some users having such faulty devices reported success.

Download latest firmware on post #1. copy it on a micro sd, plug the micro sd into your tablet and boot to recovery mode by holding volume up and power button while device is turned off. then apply update from sd card.

next time choose the right image!
[Miscellaneous Android Development] nick_1964:
From Acer Netherlands there is no latest firmware on the page ( no firmware at all by the way), I would feel fine if I had the original RV04RC04 firmware, but if you flash your device with the toolkit, you have to choose the img file on page 1 with the same version that is on your tablet.

So, if your firmware is RV04RC04, you should use that one in the Acer toolkit, but now it's to late, follow the instructions of entonjackson to get it out of the bootloop.
[Miscellaneous Android Development] Min Thura:
I chose the right image (RV04RC04). But I got error message "Your device has 'android 0x0000000015e00000 0x00000000020e8000 2 /dev/block/mmcblk0p3' in dumchar_info. Continuing could brick your device!". But I ignore this and continue to root. So now I'm in boot loop.. :eek:

I'll try with latest update zip file on Post 1. Can I encounter partition error problem if i do so ?? Thanks.. :)
[Miscellaneous Android Development] nick_1964:
If you get the partition error it will just stop ( from my experience ) but does not harm it (not more then the bootloop) maybe you have the 16 GB model ?
[Miscellaneous Android Development] Min Thura:
No, I've 8 GB model... If I encounter with partition error, what should I do ? I've to test again with older version firmware ?
[Miscellaneous Android Development] nick_1964:
When you get the partition error nothing happens with your device, it stays in the version it is, restart and it must be in the old state again, but maybe it does fix the bootloop, I don't know for sure,never had one.

If you press the volume up butto together with the power ( when your device is off ) and keep it pressed, you get a little white menu,press upgrade or something, then you get a Yellow menu, from there you can reset to factory settings, maybe that helps.
[Miscellaneous Android Development] entonjackson:
factory reset won't help. you need to apply an update zip. take the firmware update to v06 on the 1st post.
[Miscellaneous Android Development] paobig:
Thanks all guys.

I succeed to root my iconia.

You're greattttttt.
[Miscellaneous Android Development] nick_1964:
You are the expert, so I won't even dare to discuss it with you, hope you received my second donation, my mail is dead again... I think 06 is all we got, I will keep it "just to be sure" . Acer really is very careful... they don't give her buyers a "resque" tool.

And no changelog, so I don't even know what the difference is between 04 or 05, both tablets say the latest firmware is on it. maybe 04 is 05 but altered so your first hack won't work anymore.

Just to be sure I keep one original RV04RC04, my wife mothersday present... root is maybe to dangerous for her.
[Miscellaneous Android Development] entonjackson:
What i can't believe is that acer pulled all firmware updates from their website.

that's why 06 is the only thing we have here. nobody thought, that one day there won't be one single firmware update on their site.

[MENTION=5250920]Min Thura[/MENTION]: Do you know which version you had before rooting?
[Miscellaneous Android Development] Min Thura:
Before rooting, it's RV04RC04.. Why ?? Should I test with update zip from post 1 which is RV05RC06.. Is there any problem ? All I need is to fix the boot looping.. Thank you..

---------- Post added at 07:56 AM ---------- Previous post was at 07:47 AM ----------

Do you mean that update zip files no more exist on Acer site ?? I've links from global-download.acer.com, all links works (for now). Firmware versions are

RV05RC05

RV03RC05

RV05RC06
[Miscellaneous Android Development] alien0234:
friends..!!

i got a bootloop..

i try to download the stockrom at acer offcial web, but there's no rom at all (indonesia)

i need the link please...
[Miscellaneous Android Development] agentdeep:
For people having boot loop problem on RV04RC04, I have original system.img which I pulled off from my tablet before rooting.

I could upload this and try flashing it to your tablet to fix the boot loop.
[Miscellaneous Android Development] entonjackson:
The website doesn't work for me. I must pass login name and password??

If you can download, then download any zip file from there, put it on a micro sd card, plug it in, go to recovery and apply update from sd. That's the only thing you can do now.

he cannot apply the system image, because he cannot get into adb mode. he's stuck inside bootloop. he must enter recovery and apply acer firmware update from sd card.

Yeah, i got it. Thanks a lot, my friend!
[Miscellaneous Android Development] agentdeep:
Ah you are right.

But the problem if you flash update image, you will get the "invalid partition setting" error. So, still they can't fix the boot loop problem :(

Is there any way we can create an update image from pulled off RV04 system.img?
[Miscellaneous Android Development] entonjackson:
I see.

Then i would say return the device to dealer or acer...
[Miscellaneous Android Development] Min Thura:
I've successfully solved boot looping the problem in a strange way. The story is I download two firmware files RV03RC05, RV05RC06. Then I copy RV05RC06 into sdcard and update from recovery menu. But as I guess, I've to face the partition error problem. Then I test again with old RV03RC05 (which need to be extract). Also it showed me the same partition error. So I remove the sd card and format it with fat32. Then I copied both zip files to sdcard again. Before I update from recovery, I did factory reset to make sure the system is clean. Then I try again. But this time I chose RV03RC05 version zip file and no more error showed me !! And system updated successfully. Then when I check the image version, it is RV05RC05 !! :confused: I'm sure I chose the RV03RC05 one. So to be sure, I viewed the build.prop of both zip files and it's the same as the RV05RC06 version in which it's ro.build.pandora.id=Acer_AV051_B1-A71_RV05RC05_WW_GEN1. So I realized my tablet is updated with RV05RC06 version zip file. There's another thing. I now successfully got root, which I tried with toolkit and failed. I found su in /system/bin/. So the update process is not clean copy. It overwrites the existing files. I think su exists in system/bin because of last root process. In any case, now I solved my problems. Thanks all who helped me.. :)
[Miscellaneous Android Development] entonjackson:
in any way. the system.img.gz hast the state your system had before deleting apps with root.

and it contains a su binary (it's rooted)
[Miscellaneous Android Development] knak2k1:
yes, and it is possible to pull this system.img.gz to the tablet so all deleted apps are back again?
[Miscellaneous Android Development] entonjackson:
yes
[Miscellaneous Android Development] knak2k1:
ok, good. and can you please tell me how? like you wrote it at the f.a.q?

do I have to copy the system.img.gz to the external sd card, goto recovery mode and flash zip from sd card? maybe I have to rename the file?

is it safe or can I brick the device?
[Miscellaneous Android Development] entonjackson:
copy the system.img.gz to system_image folder inside toolkit directory and root (not from scratch)
[Miscellaneous Android Development] knak2k1:
I did not know that it can be so easy... thanks :D
[Miscellaneous Android Development] vijay.alapati:
Can we have a solution for A1-830 Please

Hi, can you please update the post to root A1-830 running 4.2.2 Please:D
[Miscellaneous Android Development] entonjackson:
Post the content of:

/proc/dumchar_info

/system/build.prop
[Miscellaneous Android Development] paladin881:
Hey i think there's something wrong with the zip file. I tried unzipping it with 7-zip and winrar but I couldn't do it with both. The error says the file is corrupted. Could you please unzip it then rar it and send me a link. Thank you.
[Miscellaneous Android Development] janres155:
It is an .img which is gunzipped, that's why .gz at the end. You will need a different tool to unpack the system image.
[Miscellaneous Android Development] paladin881:
I mean the toolkit not the system image but thanks anyway
[Miscellaneous Android Development] Gmobilize:
could it be that by rooting my a1-810 it isnt able to recieve any updates because of the modified system.img.gz?
[Miscellaneous Android Development] Just_Another_N00b:
That is a built-in safeguard by Acer. There are apps (playstore has at least one) to 'hide' your SU binary, so that Acer will not balk at the tablet being rooted. Stupid, but true...

---------- Post added at 01:44 PM ---------- Previous post was at 01:43 PM ----------

Please re-download and test again. The toolkit zip is not corrupt (afaik)
[Miscellaneous Android Development] Gmobilize:
ok ,thanks ,but here's the deal tough , for some reason my a1-810 is not charging or when shut down 1% by 3h so im considering whether to bring it back...

Sorry for off-topic.
[Miscellaneous Android Development] Wrightperspective:
So if I have the A1-810 and I am currently on RV18RC10_PA_CA and I want to do the upgrade to RV27RC02_PA_CA, do I just put the system.img.gz file into the system image folder or do I need to do the OTA update then move the rooted file to the system image folder and use the toolkit then?
[Miscellaneous Android Development] Just_Another_N00b:
Have you tried the soft reset? Could just be calibration? If all of that fails, then do an RMA, if you are still in warranty as this could be a hardware failure...

---------- Post added at 06:23 PM ---------- Previous post was at 06:16 PM ----------

I am not sure if you can load a new system.img.gz over an old one, maybe [MENTION=3392632]entonjackson[/MENTION] can help you out there, but as there is "unroot" available in the toolkit, I would do that first, and then try to do the OTA thing. If that fails, then do the "hide" thingy (very precise technical term here) on the root stuff, and try OTA again.

When you are rooted (and su is "visible") you will get a message you are not able to perform OTA. Acer does not like us to root their tablets, and that may (or may not) be the reason the bootloader is locked, alas.

Good luck getting the upgrade. Check with [MENTION=3392632]entonjackson[/MENTION] (via PM or so) if he has seen any success in getting a new system.img loaded on top of an old one and not upgrade the tablet to a deluxe doorstopper.
[Miscellaneous Android Development] Wrightperspective:
I tried unroot but that did not unroot the device and when I hid the SU, it allowed me to see and download the update but when I went to apply the update, the update failed. That's where I'm stuck.
[Miscellaneous Android Development] Wrightperspective:
Yeah....I'm very frustrated right now . Been trying for hours to get this thing to unroot but it won't unroot. I need to somehow flash the stock image, which I don't have or do something to get this thing to update. Anyone have a stock image of the a1-810 with RV18RC10_PA_CA?
[Miscellaneous Android Development] andrewbat:
Have you tried doing it through Linux and not Windows?
[Miscellaneous Android Development] Wrightperspective:
I now have it unrooted but it still will not take the OTA update. It keeps giving me an error.
[Miscellaneous Android Development] andrewbat:
What is the latest update for the Acer A1-810?
[Miscellaneous Android Development] Wrightperspective:
It's just trying to take me to the next one up from what I have then it should take me to the next one and so on until I hit the end. Not sure what the latest is. I'm on an older version.

---------- Post added at 04:21 AM ---------- Previous post was at 04:19 AM ----------

Has anyone had luck flashing a different firmware than what was currently on their a1-810? I know some people have bricked but I thought I had read one person that didn't brick.
[Miscellaneous Android Development] ppp10:
Mine, in Europe, has the latest firmware: AV052_A1-810_RV27RC03_WW_GEN1
[Miscellaneous Android Development] Wrightperspective:
Is there any way to make a back up zip that can be restored if the unit bricks?
[Miscellaneous Android Development] Wrightperspective:
Okay, let me break down what happened:

Got my A1-810 in September 2013 and it had RV03RC08 on it. I don't remember how, but I was able to root using the RV18RC10_PA_CA over that and it worked. I wanted to get back to unrooted so I could take the OTA update so I tried to unroot using the tool. When that didn't work, I moved my stock RV03RC08 back on the device by putting it in the system image folder and chose root. It went back to RV03RC08 unrooted. There was an update for that to RV18RC07 but it wouldn't update - it would reboot like it was going to install it but it failed. I even tried to install the update from the SD card but it failed and gave me an error that had something to do with the build prop.

At that point, I put the RV18RC10_PA_CA back into the system image folder and rooted using that image and it rooted and put me on that firmware and that firmware works. I just can't figure how to move up past that. Just wondering, though, since my tablet tells me it has an update available to RV27RC02_PA_CA and keeps failing on install, if I were to put the RV27RC02_PA_CA file in the system image folder and do the root process using that image if it will work?

I just grabbed the update zip for RV27RC02_PA_CA from my cache folder and put it on my SD Card and tried to update that but this is what it says:

Installing update...

Remove last update te_finish_update.txt...

assert failed: getprop ("ro.product.name") == "a1-810_pa_ca"

check.partition.size=[__PROP_UNDEFINED__]

Installation aborted.

If anyone has a solution for this or a stock system image for RV18RC10_PA_CA and you can share that with me, I'd appreciate it. I'd love to update. Thanks.

UPDATE: I was able to go into the zip file and remove the update.txt from the file so now I just get

check.partition.size=[__PROP_UNDEFINED__]

Installation aborted.
[Miscellaneous Android Development] Wrightperspective:
Let me ask this question:

When there is an update, the system image gets replaced with the next system img up from that one. So, if that's the case, as long as I put the next system img that is available for my tablet in the system image folder in the toolkit and root, won't that work since I would be replacing the system image in order like the update?
[Miscellaneous Android Development] fnldstntn:
No...I've tried this and my device bricked...
