I fot full Root now with method 3.
First do a nandroid, unlock the bootloader and install cwm patch1 first
Then apply the zip-file from method 3.

Reboot and Full Root with R/W

Depends on your bootloader version apparently.
None of 3 methods work 4 me

Need a patched bootloader

Update. Got root+rw remount to work.
The problem was a weird busybox version that mount references.

Can anybody give a quick reference on how to extract current firmware so i can share.
1.017 seems to be a rarity out there still...

How do you do a Nandroid backup without having CWM installed??

Edit:
I looked it up on the internet and you can't do that.

You can by using Clockwork and then after flashing back remove the root.

Can anyone confirm that the following commands in the Android Terminal work to UNroot our tablets?:

[...]

then after booting you'll still be rooted, to unroot you'd need to open terminal again and:

su
mount -o remount,rw /system
rm /system/bin/su
rm /system/xbin/su
rm /system/app/SuperUser.apk

then reboot, you should be back to full stock.

Trying via Method 1

Installing CWM looks cumbersome and the fact that there are no CUSTOM Roms to flash (except CM for A700 but I dont have that one) I see no point!

Here is what I get VIA method 1 its still hanging here, device is rebooted and stuck at ACER logo. Unpluging the USB back and forth brings null results...

I ROOT'ed two A701's before.. although I used dif methods..

I just got my A700 yesterday, tried all three methods but only #2 worked, and only by typing in ADB commands manually.

I'm looking forward to more custom ROMs coming out, especially running Jellybean. I'm somewhat disappointed in the lack of dev interest for the Acer tablets, they have great potential and are currently selling at lower prices (I wanted to buy the Asus Transformer Infinity but didn't want to pay an extra $100).

Oh, RiceDie.. I suppose I'm going to see you slumming around in "this" forum also? :good:

As with the root, on my 701, I could use method 3, however, I had to goto the SU site and flash the binaries. Agree with what was said earlier, about BusyBox being messed up. As SU couldn't update the binaries by itself.

Of course I got the super brick with that crappy original CWM, so hope to get the tab back this coming week.

Well, there's not a lack of development per say, just a lack of "Devs and Modders" because........

They all bricked their tabs getting all the initial issues worked out (so other people didn't), and some still waiting for them from the Service Center! :laugh::laugh::laugh:

Hope to get mine back next week....

So, I rooted my A700 using method #2. (Having stock FW AV043_A700_1.055.00_EMEA_DE).
It does work excellent - except HDMI out.
I am pretty HDMI worked well before rooting. After rooting I can see a picture on the external screen, but the touch screen is not working anymore. When I disconnect HDMI, the touchscreen does work instantly. Any ideas?

I can remember my HDMI worked fine (701) as I played the monopoly game. Shortly before I bricked it with the original CWM.

Might just try a reboot.

I have the same FW running on my A700, and I also rooted it with method #2.
HDMI is running without a problem. The touchscreen is still running while the Tablet is connected to my TV.

Did you already restarted the A700?
Sometimes it behaves really strange, but for me a restart always fixed the problem...

Hey MD! Oh cr@p! I hope I wont brick this A701!
I remember you bricking your A701 is it still in service from that time?

I hope you don't also! I think the current CWM is ok, and the Super Brick bug is hopefully a thing of the past. (however, a couple guys this past week bricked their 510's, and they can't remeber which version of CWM they were using!!! Duhhhh)

If and when I ever get mine back, I'll finish the custom rom. Hopefully will get the rest of the issues with the OC kernel worked out (not that I think it needs it). Really can't do much of anything, as I have no tab to do testing, except my 501.

Yeah, mine is still in the local service center. I have no idea what the issue is.

Should have just been a mainboad change. Well, they did, installed the OS, the tab worked. But, when I picked it up, NO 3G! Would not even recognize Sim card as being installed. So it never left the shop.

Second mainboard ordered. Not sure what went up with that one, but whatever, they had to order another part. They should have recieved it last week. So I would HOPE, this week I get it back. Will have the wife call them....... again. It's been a week and a half since last call.

Regardless, it's past the 45 day mark in the service center, and according to Russian law, The Place I bought it from is obligated to replace it, or issues a refund. (should opt for a refund, as the tab is now 50$ cheaper than when I bought it).

Glad to see you in the forum! :good:

Hey MD! I didnt install CWM on any A701 yett! Will do once there are Roms to flash!
Im kinda disappointed with the lack of Roms therefore I tend to mess around with my HOX more.
I guess Im a flahaholic with OC UV favor :laugh:
Thanks for the worm welcoming!

Is JB rootable with the same methods (e.g. method #2)?
Can I go back to the original kernel after rooting while keeping root?

Hi,

I have a stock A700 running the latest JB Rom.

Simple question, how do I root ? Is this thread still relevant, has there been new devs since, is JB specific in regards of unlocking/moded recovery/rooting ?

thanks

bschrib · Oct 19, 2012

Hey all -- I'm trying to get some root on my new A700 but I have some questions (after doing lots of reading through the forms). Hopefully the community can help me out here?

1.) I see that so far the only methods of obtaining root involve unlocking the bootloader and then running some sort of root.img file. However I also noted in the bootloader unlock thread that you CANNOT relock the bootloader via typical "fastboot oem lock" command, so the only way to restore a locked bootloader is to flash a backup, or original firmware. Is this correct?

2.) CWM ~DOES NOT~ work for the A700, so far as I can read (at least not reliably..?), or more specifically you have to have specific bootloaders for it to be compatible. With this in mind, would it be possible to just "fastboot boot cwm.img" and make nandroid backups, without actually flashing the CWM recovery, or would that too risk bricking the device?

3.) Ultimately my goal is to download the OTA's that my device is getting during it's journey to the OTA JB 4.1.1, however since the /cache/ directory is locked I understand that I'll need root to accomplish this, so if I understand things right, the first thing I'll need to do is to unlock the bootloader (which I can't relock easily), then hopefully I can boot to cwm.img and make my nandroid backups, then I should obtain root via the provided root.img files in the root thread (method 2 is reported as working), does that sound right? Since ultimately my goal is to get updated to stock ~EVERYTHING~ JB 4.1.1, will I be able to revert these changes at the end of this process, or will one of the earlier steps prevent me from actually getting to 4.1.1?

Currently I've got a completely stock device with original 4.0.4 ICS on it (I had to order a replacement from Amazon, first one had a patch of dead pixels and something stuck between screen).
Android Version: 4.0.4
Kernel version: 2.6.39.4+
Image Version: Acer_AV043_A700_RV05RC02_PA_CUS1
Build number: Acer_AV043_A700_1.017.00_PA_CUS1
Image P/N: FM.S1MA0.00A

The reason that I want to get the OTA update files is so I can pull it apart and see if there's someway to get root in JB (MD indicates that we just patch the boot.img file, right?)

Sorry for the long post, just hoping to get some clarity on this before I jump in and start making changes that are irreversible.

If you hold off for a couple days, will post a insecure boot.image, so you don't have to do all this stuff.

Simple unlock bootloader, Fastboot the new boot.image.

The above method, is outdated, and doesnt give true root/System RW access.

Already works great for 701. Just need to modify 700 boot.img

Thank you so much MD, I really didn't want to go through all of that.. hahaha.. I'll just wait patiently. In the meantime (for myself and any other users who jumped on the lowered Amazon Price), should we stick around on ICS, or do you think bumping to JB would be OK?

Thanks again man.

Well, I can't tell you what to do.

Is JB Better? Of course. I feel they somewhat fixed some things, Definately a lot smoother. Also, temp seems to be lower. Display a bit more responsive.

My advice before taking OTA. (I took mine immediately after going through wizard).
1. If you have installed any apps, like launchers, Task killers, etc, uninstall them).
2. If you activated that useless Anti-virus app included, kill it.
3. Try to get it as close to stock as possible.

Then do OTA.
