Acer a3 830 SU fails + Onda v919 DualOS

Acer A1 830

Everything is okayed (using T3) , into recovery/APPLY UPDATE FROM EXTERNAL SOURCE (sd card) , SU 2.65.ZIP selected (I have tried several different versions of SU to rule out bad file) but fails with :

Verifying update package

E:failed to verify whole-file signature from /tmp/sideload/package.zip

E:signature verification failed

Any help on the above ?

Second question : Could Onda v919 DualOS be rooted using same/similar procedure. I am bit reluctant to try because DualOS business (Win10) - anyone tried successfully ?

Any advice and comments highly appreciated !

temp cwm root method

if it happens again just reboot in to recovery mode and hit the reboot option and this should fix your issue my dell venue 7 dose this and this is how i fix it

[MENTION=4821597]social-design-concepts[/MENTION], what are the chances of being able to use something like Safestrap Recovery or something similar on the Intel devices with locked bootloader?
[Miscellaneous Android Development] redleader20:
It won't I tried everything there is exempt twrp and cwm with besides the temporary version they don't support the Dell venue 7
[Miscellaneous Android Development] Droidriven:
I thought as much, I figured if it were possible then someone would already be doing it. Oh well, wishful thinking. More and more devices are coming with locked bootloader and its becoming a PITA, lol. It's a conspiracy! They're killing all the fun.

Thanks for answering and thanks for what you've done that is possible, its better than nothing.

Keep up the good work.

[MENTION=4821597]social-design-concepts[/MENTION], I have another question that you may be able to help with.

I have an Azpen A750 with AMI BIOS, I was going to attempt installing windows 8/10 on just to see if it will work but when I go into the BIOS to set the boot priority to but from USB it let's me select the option but it doesn't keep what I select, its not letting me change the boot order to start the install process.

Got any ideas?
[Miscellaneous Android Development] social-design-concepts:
Sounds like setupmode might be disabled some devices require you to set a uefi/bios password before you can change options.

Is this 32bit or 64bit efi device?
[Miscellaneous Android Development] redleader20:
It should have a save changes button
[Miscellaneous Android Development] Droidriven:
No, you aren't understanding, when I go to boot priority and open the list of boot devices, I can select an item from the list of devices to boot but when I select USB it doesn't actually select USB and keeps the default setting, it doesn't even attempt to change to what I'm trying to select. If it would actually let me select something then I could save changes. No matter what I do it won't accept any selection. I can change everything else in the BIOS but boor priority will not accept any new selection. I'm wondering if they have that option locked.

---------- Post added at 09:52 AM ---------- Previous post was at 09:48 AM ----------

It has no password set in BIOS, there was never one created, I can create one if needed. Are you saying I can create the password and then it will allow me to make a new selection?
[Miscellaneous Android Development] social-design-concepts:
Yes you might have to create a password before you can save
[Miscellaneous Android Development] Droidriven:
I'll try that, I was avoiding creating a password, I don't like a passworded BIOS but if that's what it takes then so be it, thanks.

SOLVED

If anyone with this tablet experiences the below problem, I was finally able to root by letting my screen timeout and go blank between each step. Otherwise my tablet seemed to register a double click and rebooted when trying to select anything with the power button.

__________________________________________

I'm so close to finally rooting my Acer B1-730HD (I think) but I can't install supersu. When I get to the point where you select install zip from the recovery menu, I have a problem. My Acer reboots when I push the button to select so I don't get a chance to install supersu.

Anyone know a work-around?

"hi there people,

i was able to reach to point 5 but when i try to install zip it doesn't work. it says that: "e: can't open /sdcard/update.zip".

any suggestions to solve this problem?"

having similar issue, but I DO already have sd card. Device is Asus MemoPad 7 ME170C running Lollipop 5.0. I have been running it for months then all of the sudden it constantly disconnects wifi after usually less than minute. I have tried bunch of things I read to try but nothing has worked so I ended up here and was going to try to reflash it. I have the official release from Asus. Not really sure how to do that and was trying to put it on sd card and then use the tethered recovery tool and direct it to the zipped ROM? May be best that it didn't work since I wasn't sure if that was correct way to do it, LOL. Also tried to root it but it won't find the sd card. tried to go to advanced screen and mount external sd but it won't work? The tablet shows the SD card and I can see the files, but when go in recovery mode it doesn't find it anymore?
[Miscellaneous Android Development] Droidriven:
Do a Google search for:

"How to return to stock (your model number)"

That should give you tools and instructions.

Guys, i have a little problem. I have an ASUS Fonepad 8 (aka FE380CG/FE380CXG). With this tool i can boot only CWM which works very well. But, if i try to boot the TWRPs, i cannot control it because touch isn't working. Is a bug of my device or not?

No, same problem here with Onda V919 3G Air DualOS. Mouse on OTG solves it AFAIK.

I have a Colorfly I 977 A3G , with Intel processor, can i make it with this apps?

When it not run, is the device defect?
[Miscellaneous Android Development] Giovix92:
No, because the recovery files are flashed on /tmp. When you reboot your device, /tmp will be erased. In fact, you're device, if you try to boot any recovery with this tool, will be NOT affected. Is absolutely secure. If you would to flash anything like a custom rom, make sure that you have the bootloader unlocked, or you will hardbrick your device.

Bootloop after restore of backup made with CWM

Hello,

rooted my Lenovo Yoga Tablet 2 - 1050F sucessfully with "IntelAndroid-FBRL-07-24-2015.7z" and the explanation on the first site of this thread. I also made a backup from my whole tablet to the ext. SD-Card using the "Tethered Temporary CWM".

Yesterday I decided to restore this backup I made directly after rooting and did it also with the "Tethered Temporary CWM" via "Restore backup from ext. SD-Card". All seemed to be completed fine, but when I tried to reboot the tablet it hangs at first on the startup screen with the Lenovo logo and after a while it reboots to the internal recovery mode.

When I choose "reboot to bootloader" from there the same things happen again. So I can't get Android to work.

Are the "Backup and Restore" functions not working on this "Tethered Temporary CWM"? And how can I get my Tablet working again?

Thank you.
[Miscellaneous Android Development] Giovix92:

Hello

I have a lenovo tab s8-50f and when I tried it I can not install SuperSu.

What should I do?

Thank you
[Miscellaneous Android Development] Giovix92:
What recovery have you booted? How you have tried the "installation of supersu"?
[Miscellaneous Android Development] alexeire:
I go into the boot loader. Then I went on to the recovery mode after that when I hit apply update from external sd card and go on supersu it said Install aborted. What should I do?

Thank you for help.
[Miscellaneous Android Development] Giovix92:
Don't use stock recovery. Follow this steps:

1-Install required fastboot drivers for your device on your pc

2-Boot your device into fastboot mode.

3-Open launcher.bat

4-Type ACCEPT

5-Select CWM (nr.5)

6-Try the T2 Option. If the CWM doesn't boot, after the message "completed", press enter and try T1, T3 or T4.

7-After you have booted the CWM, press install a zip and select install from SD Card. Then select your supersu zip and confirm. Wait a few seconds and reboot.

8-If the cwm shows you a message like this: "Root access is possibily lost. Fix now?", simply press no.

Enjoy!
[Miscellaneous Android Development] alexeire:
Ok.

Thank you for help.

Try to redownload the launcher. What option have you selected? T2? T3? Have you installed your device's fastboot drivers?
[Miscellaneous Android Development] alexeire:
I have selected every T. And I think I have installed my devices fast boot drivers.
[Miscellaneous Android Development] Giovix92:
Verify if the fastboot drivers are installed. If yes, reinstall them. The launcher recognize your device? Is the screen blue and not red?

What tablet do you have? Is it by any chance a NuVision tablet? I have the same Baytrailxxx fastboot but it worked for me. Since the first device status says FASTBOOT-ONLINE, it seems that you're doing this via fastboot mode (droidboot). Reboot back to system and try again and it should work.

How can I tell if my tablet has a locked bootloader? It's a android 4.4 NUVISION_8_INTERNET_TABLET, build version: TM800A510L-20150810. I tried fastboot oem unlock but it says unknown OEM command, same with fastboot oem device-info. Can I remove SuperSU and the bin files?

I'm asking because after trying this method with T3, the system rebooted but there was no SuperSU apk and I remember seeing on the OP that some devices don't have space for SuperSU. I'm wondering if that was the case with this tablet because it lagging a lot. When I attempted to install SuperSU.apk from adb, the tab rebooted and was stuck on bootloop at the intel screen. I powered off and now it's stuck on the NuVision screen. Can anyone help me? [MENTION=4821597]social-design-concepts[/MENTION].

This procedure worked for me where every other one (iRoot, KingoRoot, you name it) failed, thank you very much for your help!

By the way, the device I rooted is an Intel-based Onda v919 3g, so I can confirm this method

works

for that tablet. I chose CWM recovery when asked in the batch program, and trigger T3 right after that.
[Miscellaneous Android Development] EdgeStarfckr:
wow still nothing?
[Miscellaneous Android Development] ramiabouzahra:
Hmmm, I had my acer iconia a1-830 rooted using a temporary root (every reboot removes root) using kingroot.apk. I basically tried twice and rebooted and I had root. Then it got soft bricked and I restored it but then it was stuck in a bootloop. So since root was gone I took it down to the shop and got a new one. Then I rooted that one with permanent root (mykit bach something like that) and that worked. Now I really want to have a recovery only for backup purposes since I dont want what happend to the first device hapening again. Ofcorse, the rom toolbox lite was the problem so I dont use that anymore but better safe than sorry. Now during download it gave me an error saying the file contains a virus, I tried all links but no luck. Even windows essentials said '' threat neutrilized'' (it was in swedish so I am trying to translate the message it was showing) like it was a major threat to the computer. Are you sure this is safe?

Choosing no.5 cwm and from T1-T4 all doesn't work. Recognition by the pc isn't a problem but soonest a selection is done and the tab goes into reboot and fastboot screen turns up on the tab screen, it wait for a command and stops there.

Rooted Acer Iconia A1-830

Hey! Just wanna say thanks for this. I've successfully rooted my Acer Iconia A1-830 tablet, though there were some hiccups along the way.

First of all, the latest FBRL file provided by the OP . Trigger 3 doesn't work at all, and the rest somehow works but when the custom recovery goes up, DroidBoot always gets in the way. Whenever I press the volume keys to move the cursor in the recovery (for example, the setting to install the SuperSU zip), it also affects DroidBoot. Like, the cursor there also moves. And when I select something in the recovery, I also select something at the DroidBoot menu. It's kinda hard to explain. But long story short, it didn't work lol. :good:

What worked was an older version (Not sure tho since it was posted by another member) which was linked here:

http://xdaforums.com/showpost.php?p=58051736&postcount=68

I think I used Trigger 2. I forgot lol I was busy meddling with my newly rooted tablet. :angel:

I have some questions to ask tho.

I want to try to install some custom ROMs (don't even know if there are ROMs that support this device :cyclops: ), but before that I want to create a backup first. I think it is called nandroid backup. I'm fairly new to this so please bear with me haha. Anyway, in order to do that, I have to unlock the bootloader and install a custom recovery. They (the internet) say that when you are rooted, you have already unlocked the bootloader. So, by doing this rooting method, have I also unlocked the bootloader?

I don't think it's unlocked tho, but I want to know for sure. :victory:
