Tried this on my ACer Iconia A 810 got the success message below but still saying not rooted :confused:
[Miscellaneous Android Development] nikagl:
So... why are you using this method and not the one recommended for your device?

[GUIDE] Firmwares, ROMs, CWM, Root - Acer Iconia (MTK) Tablets
[Miscellaneous Android Development] silverblack:
Because most of the links are either broken or are in russian.

I dont even know which link to choose on that page.
[Miscellaneous Android Development] nikagl:
Then ask in that thread what to do instead of just trying the not-recommend method. Nevertheless, using this method it should work too. Why do you recon you do not have root? As you can read all over in this thread mounting system will not be possible, so if that's what you expect, it will not work using this method. The other method won't enable that for you either, but you will be able to mount from the recovery.

The other method is described in these posts of the other thread:

Hello devs and members of XDA. This is my first post :)

I have an Acer B1 A71 tab and wanted to apply root access using the toolkit but I am unable to find the RV04RC04 pre rooted image, so I tried root the device with Kingroot. Everything was good, I had root permissions as per root checker app, then I tried to supercharge the device using the V6 supercharger. After running the script using script manager, it said that the device was 50% supercharged and to have it 100% I needed to patch the services.jar. Everything good up to that point. I used the Ultimatic Jar patcher tools but I think I messed it up because when the program finished the patching process, I installed the new services.jar and rebooted but then the device got a bootloop. I was able to restore it (thanks to the xda community) flashing the custom rom using the stock recovery.

After this long story, my issue is the following: I want to run the process again, but this time using this toolkit, but I am unable to find a suitable RV04RC04 pre rooted image on the internet (the file on this post is unavailable). Is there a way someone on this forum could provide me with that (a link to download or something)? Should I flash instead a stock RV05RC05 and then use a RV05RC05 pre rooted image (if that is even possible) because that pre rooted file is still available? Thank you for your time :)

PD I don't know if I shoud ask the following on this thread but, after successfully patching the services.jar with the ultimatic jar patcher tools, what should I do next? I mean, the services.jar is on the folder of the tool, what next? Transfer only the services.jar file to the SD and continue with the script? Should I use any other method instead?
[Miscellaneous Android Development] nikagl:
Hi,

Please check out the following thread:

http://xdaforums.com/android/general/acer-ax-b1-t2875894

You can root using a custom recovery which should give you better root than the one in this thread. With root in this thread, it will not be possible to modify anything in your system unless you know how to mount the image in linux and modify it manually before importing.

Regards,

Nika.
[Miscellaneous Android Development] guichochepe:
Thank you for your reply! The russian guide by [MENTION=1089616]fired[/MENTION]iamond is no longer available, but I found a method to unlock bootloader +CWM using SP Flash tools on the internet. Should I use that method? I've read how to do it on other devices and I think it is almost exactly as the guide I've mentioned fo the B1 A71 device, the only different thing is the files used and maybe the values entered in the tool.
[Miscellaneous Android Development] nikagl:
I can't say anything about other guides on the internet. Also, ask questions in the relevant thread, in this case not here (noone knows about these methods in this thread as its about other methods). In the other thread, use one of the newer guides:

[Miscellaneous Android Development] guichochepe:
Thank you my friend. That was exactly what I was looking for. I will read both posts and decide which method I will run, maybe as indicated in post 925. I hope I am not dumb enough to damage my tab. Once it is done, I will let you know (: Thank you once again
[Miscellaneous Android Development] guichochepe:
Hi [MENTION=313379]nikagl[/MENTION] I didn't notice that I was talking to the person that created the flashing firmware guide s: I gotta thank you for the guide and for the help provided from the past couple of days. I already did the steps on your guide on post #925 but I noticed that the guide is to flash stock ROM, and when I flashed the firmware, it worked because you explain the process very well. However I trully want to have total control of my device, meaning, have bootloader unlocked, CWM to flash stuff from SD card and most of all, root access. A did notice as well that, on the download section, there is a zip file called unlock B1-A71 which contains two folders: 4.1 Rescue and 4.1 Unlock. Is that the way to unlock bootloader and flash CWM? As it is not mentioned on your guide, how could I achieve that? How do I gain root access? I apologize for so many questions and I hope you can help me.
[Miscellaneous Android Development] nikagl:
You should be asking in the other thread, this thread is not about that method. And yes, if you flash the stuff in the unlock folder, you will receive CWM. If you use CWM to flash SuperSU you can get root.

Hi, I bought my A1-80 a while back and I want to root it now. some time ago I tried to update to kitkat from about update but just got (and still do get) Update service temporarily unavaliable Status code: 1001. so that was out of the option, I put a microsd card into my tablet and downloaded the jellybean image from acer's site in hope that might get it working nope! when i tried to update from sd I got an error something to do with keys and the update was "acer-test-keys" and my tablet was "acer-test-k" here is a screenshot of my About tablet area: XDA won't let me post links yet so here it is i . imgur.com/dcGW6RL .png I was confused about which image thing to pick on here because my tablet says RV03RC08_WW_GEN1 but on here there is no RV03RC08_WW_GEN1 just a RV03RC08 image, Is that what I should use?
[Miscellaneous Android Development] sugi6666:
I guess so. If you have trouble updating, just use sp flash tool.

- download your system.img.gz and extract the "system.img"

- get Flash-Tool from here. http://www.mediafire.com/download/8mi71a1fs05qnap/A1-810+Unlock+and+CWM.rar

- navigate to drivers and install the MTK drivers, you might need to turn off the driver verification

- if drivers are installed correctly, navigate to SPFT open Flash-tool.exe

- in flash-tool open "scatter loading" and choose "/810 Unlock and CWM/MT6589_Android_scatter_emmc.txt" file

- uncheck everything (Preloader, Recovery) and check on "Android" and then choose your system.img

- press download, turn your tablet OFF and then connect to your PC

- wait until you see the green circle

Try following:

Download the Acer Image for RV05RC05 here: http://goo.gl/h5ycC

Put it on your SD card, start the recovery (Vol+ and Power). Choose "delete user data" to clear up memory and cache.

Start your update. It will stop at about 20% with the fail notification as you already know it.

Once the notification appear select "Reboot" in your menue with your power button and hit it. Then your B1 should reboot and boot up properly in a working system. It is possible that afterwards your B1 shows up as RV05RC05.

This procedure has been reported to have worked successfully on bootloop with faulty RV04RC04.
