Does it boot into fastboot/droidboot via hardware keys? The V8 3830 NoModem is actually unlockable to be able to boot unsigned/modified boot.img recovery.img
[Dell Venue] Andrij90:
Yes I boot into fastboot/droidboot via hardware keys
[Dell Venue] vampirefo:
Flash correct boot.img and recovery.img then boot into recovery scroll up and down to activate misc partition. You can factory reset if you want, reboot and you should reach desktop.
[Dell Venue] Andrij90:
And how can I check it good to flash?

During the firmware seems to be alright

can I need fastboot erase boot and fastboot erase recovery?

Ok, I was able to get adb working without a system, takes a while to do it. but a system can be restored from a tablet that has deleted it's system.

You need a backup from same type of tablet.

to backup tablet

make sure system is small as possible, if system is too big you will run out of space.

busybox tar -czvf /storage/sdcard_ext/v8_kk_system.tgz /system note /storage/sdcard_ext is my micro sdcard if you is different use it's name.
place the v8_kk_system.tgz on a micro sdcard insert in tablet to fix.
boot tablet into fastboot flash the fastboot from v8 dev version reboot, flash adbd, fastboot oem startftm

adb push mksh /system/bin/sh

adb push busybox /system/bin/busybox

adb push '/home/vampirefo/Desktop/dell_boot/dell_dump/system/lib/libz.so' /system/lib/libz.so

adb push '/home/vampirefo/Desktop/dell_boot/dell_dump/system/lib/libc.so' /system/lib/libc.so

adb push '/home/vampirefo/Desktop/dell_boot/dell_dump/system/lib/libcutils.so' /system/lib/libcutils.so

adb push '/home/vampirefo/Desktop/dell_boot/dell_dump/system/lib/liblog.so' /system/lib/liblog.so

adb push '/home/vampirefo/Desktop/dell_boot/dell_dump/system/lib/libstdc++.so' /system/lib/libstdc++.so

adb push '/home/vampirefo/Desktop/dell_boot/dell_dump/system/lib/libm.so' /system/lib/libm.so

adb push '/home/vampirefo/Desktop/dell_boot/dell_dump/system/lib/libusbhost.so' /system/lib/libusbhost.so

adb push '/home/vampirefo/Desktop/dell_boot/dell_dump/system/lib/libselinux.so' /system/lib/libselinux.so

now you should have a working adb with root permission

restore backup
cp /system/bin/busybox /sbin/busybox
mount -t vfat /dev/block/mmcblk1p1 /mnt/sdcard
busybox tar -xzvf //mnt/sdcard/v8_kk_system.tgz

su vs super, factory reset, apps+data on sd

Hi, I have successfully rooted my Acer B1-730HD with x86 cpu.

But then stopped working some things. After opening the security menu in the Settings application crashes. I also can not set the display tiemout. But mainly, I naively thought that if I have root, I'll be able to install the application on SD. And that some of them (maps) start storing contents to the card. As far as I understand it now, to work with the card must be adapted to the entire system, root is not enough. In addition, some of my applications stopped working completely with the root - for example Total Commander.

Titanium Backup tells that I use the SU which may cause conflicts and proposes to use the SuperSU.

I also read somewhere that after root with myKIT I would not do a factory reset from the boot menu.

Question 1. I can do a factory rest?

Question 2. How to replace SU for SuperSU?

Question 3. Is there any way to solve application installation and allow apps to storage data on SD in Android 4.4.2?

Thanks.
[Dell Venue] vampir74:
Why u not select the option 2 to install super su when root ..., just install Supersu from play store then delete superuser...

Download the flash package in post #2 for your device.

Extract it

Copy the image files for system and boot to your fastboot directory if you haven't set up the paths

Boot to bootloader and connect tablet to PC

Open CMD in the file location of the image files or in the fastboot folder where you copied them if you don't have the path set up.

fastboot erase cache

fastboot erase system

fastboot flash system systemimagefilename.img (I can't remember exactly what it's named in the file)

fastboot flash boot bootimagefilename.img (Can't remember how this one is named either)

fastboot reboot

You can do a factory reset in recovery if you like before these steps to remove any userapps and data that you may have had previously installed.

The recovery boot on A1-840FHD, i was able to flash SU ;)

Nice find on the method to launch the recovery, overwriting cp. How did you found that oem backup_factory use "cp" ?

Did you used custom code to make recovery.launcher and recovery.env or is it common binary ?
[Dell Venue] social-design-concepts:
it's in all the init.rc i've reviewed this method should work on almost all intel with droidboot the /system/bin/cp we replace is in the fastboot.img ramdisk not the one in the android system.img

its a custom program recovery.launcher is just the trigger all the magic happens in recovery.envsetup once i work out a couple of things the source will be posted.

and thanks for confirming

it's not in a format for flashing through recovery it they are in image format for flashing through fastboot but fastboot flashing is broken on the Acers. . . dumps in the .7z files would have to be converter to a format suitable for recovery flashing with one of the many modern rom kitchens. . . . its on my weekend agenda to convert them if time allows.

Thanks a lot for the tethered recovery. Worked for me with the Acer Iconia tab 8 A1-840FHD.

For others looking to do the same here are the steps i followed.

1. Download and extract the main myKit_batch....

2. Download the tethered recovery package and copy the downloaded .7z file to mykit_downloads folder

3. make sure adb and fastboot are working. Download and install Acer drivers if needed

4. Download and place copy of latest SU on the device.

4. Follow the commands as explained by OP to boot into recovery.

5. Once in CWM recovery install SU.

6. Voila ... You now have root.

I deleted all the bloatware from the tab.

Big thanks to social-design-concepts for all the hard work. I wanted to also thank JoeKimpel, streak4m3, and mjoyas for testing fastboot flash on the rooted system.img so we knew that was another option for everybody. It's easy when you test it yourself and it works to just say "Here it is."

Could somebody test one more thing? I have installed all of the various versions so far and in all of them you cannot make any changes to some system files like build.prop. Even pulling the file and pushing it back with permissions causes a boot loop. If someone can verify this. You will have to fastboot flash the system back to get it to boot again. If someone can test it just drop me a PM with the results.

this statement confuses me?

no need to thank me it was a community effort. I wish I could of tested things more myself but I own a venue 7 so it was all you guys that deserve the thanks.

to the users I sent the original rooted system.img too I apologize for not giving it to you all sooner but I had given it out to 4 other users in the old forum shortly after I got it with instructions on flashing with fastboot flash system system.img.gz and report their success or failure and they never responded with success or failure after so I wasn't really comfortable giving it out until the ability to unbrick finally came out Friday.
[Dell Venue] cline2:
Before root it can't play video and after root still same. So might be the 4.3 problem and high. Dunno. Have you tried HBO Go and AT&T U-Verse if u are at&t subscriber.
[Dell Venue] jp0555:
Not with at&t so I don't know. But I know if root is visible to some apps they won't work. At least that was the case with a rooted kindle fire, the last device I watched TV on.
[Dell Venue] social-design-concepts:
did they work before root?

we don't have many tv options in cincinnati ohio but Time Warner, cincinnati bell fioptics and satellite, and satellite and time warner are the only ones with tv apps so i cant use them since i have cincinnati bell fioptics.
[Dell Venue] jp0555:
The directtv app works for me right now on V8 no root( couldn't get isoc drivers to work). I was just suggesting root cloak for him since prime videos on rooted stock kindle fire only works when using root cloak. Also I thought I saw some where that Hulu and some other TV apps needed root cloak or something similar.
[Dell Venue] cline2:
I said before root. HBO Go wouldn't play after HBOGO logo but Netflix works fine. After root. Still same thing except Netflix. I don't know why.
[Dell Venue] kairnage:
I was just saying when something works it's easy to just drop it out there assuming it works. Many times when you asks for volunteers nobody wants to step up even with a working unbrick. Like you said it's nice to have a community really helping.

I was going to try fastboot but was waiting for my second venue to show up, but the dev files came out first.
[Dell Venue] social-design-concepts:
if you still wanna try power off the device wait for the charging animation and power it on holding the vol up and power button screen should stay black but this should force download mode / clover-view device be sure to skip finding drivers from windows update and if you installed the driver already it should install best to do with device manger open you should see intel soc with Intel Soc USB Driver and clover view plus something or other under it. unplug power cycle the device and then follow the process in the post. the time its in clover view mode is so short by just plugging it in powered off it in it almost always fails with device disconnected or some thing or other dunning the installation. it really is the hardest part.
[Dell Venue] jp0555:
I'll try that tomorrow thanks. I think I may have messed up adb driver, adbcomposite, android phone,etc drivers trying to get it to work. Is there any way to restore the defaults?
[Dell Venue] social-design-concepts:
sorry if you can't guess im getting alot of notifcations this weekend i was off for a few hour and just skimmed things
[Dell Venue] social-design-concepts:
boot to droidboot as long as u see a adb device in device manager that part is good that's power off and power on holding vol down and power but i think charging mode adb is the same hardware ids so it should install the adb driver just charging off the pc. if you don't see the cloverview plus under intel soc it wont work, it enters this mode for a few seconds ever time you reboot or power on the device while plugged in to the pc. so open the device manger then plug your tablet in powered off it you should see it under intel soc for a couple of seconds at least before it loads boot.

that's your pro hint the device enters download mod momentarily in between the different boot modes well at least on the v7.

when i say boot modes im refereeing to charging mode, boot mode, droidboot mode, recovery mode every time it switches between these it drops to download mode / cloverview plus for a split second or two
[Dell Venue] jp0555:
OK thanks, I'll try that tomorrow some time, thanks. I ran out of thanks for today thanking like half of your posts and some for my phone. I think this is the first time ive ran out, thanks.
