I root 4.4.2. say complete then reboot supersu it's not appear and no root permission.

I booted in to recovery(4.4.2) and wipe cache then say E:Mount recovery log bla bla bla.......................................

I can't reboot to system because It's display Acer Bootloop.

and then I flash recovery(4.2.2) on fastboot to hope it's not show E: Mount recovery..... . it pass but it cant boot. It's show Usb icon.

I flash recovery (4.4.2) to hope everything is back to normal. it pass but message "E: mount recovery" still show.

I flashed fastboot boot recovery (4.2.2) to hope back to stock rom(4.2.2) then I flashed system.gz(4.2.2) result in fastboot is okay but have one message " cannot remove /cache/fastboot.tmp"

I flashed system.gz(4.4.2) it show message loop Fastboot Offline ! Fastboot Online. Fastboot cmd waiting.

Result on fastboot

- Recovery(4.2.2) pass but can't wipe cache . it's not have message "clear cache" then auto reset device into usb icon.

- Boot(4.2.2) pass but still show boot(4.4.2) when I go to Fastboot or Recovery.

- Fastboot(4.2.2) pass but can't flashall 4.4.2 img file. it's say fail to flash.

after i get back from lunch i'll pm u ok , you shouldn't be mixing and matching images but looks as if you were able to flash the 4.2.2 system.img.gz correct? and it flashes the 4.2.2 boot.img with no issues? does it boot into recovery by selecting recovery from the droidboot menu?

Ok I'm just gonna upload the original ota update to KitKat tonight being you can still get into recovery you should be able to just reapply it and that should resolve your issue if it doesn't apply I'll put together something custom for you situation.
[Dell Venue] Pitbullfreak:
Is there somewhere for the B1-730HD Custom Roms and kernel ?
[Dell Venue] exad:
There is no device thread and there is no compatible custom recovery. Also, I don't believe anyone has managed to unlock the bootloader to allow flashing custom roms. Acer themselves have stated they have no plans to allow unlocking of the bootloader. I am going to try to port TWRP or CWM when I have time and see if I can manage to flash it. This tablet went on sale for 100$CAD here and is quite amazing for the price. So far after root and removal or all the Acer bloat, this thing is pretty damn zippy. Custom ROMs would be AMAZING but there doesn't seem to be any Dev interest.

A1 830

It's not work with my acer a1 830. Anyway, I got a small update ( 6mb ) from acer this morning.
[Dell Venue] ZooloZ:
How to revert to stock?

How do I go about using the items from post #2 to go back to stock?

I have an Acer Iconia A1-830 4.2.2 that I rooted, customized (removed some stuff) and then OTAed up to 4.4.2. Of course this has left junk behind now that I am non-rooted on 4.4.2 (due to the OTA update) and my camera seems to not work. How do I use those files from post #2 to go to stock 4.4.2? I imagine I just need to reflash the "system" part of it to get rid of my customizations as the recovery and fastboot have already been OTAed up to 4.4.2.

I did try using fastboot to simply do

fastboot flash system filename.system.gz

It said max size is 600 MB or so and the image was around 800 MB, so obviously this isn't the way to do it.

Do I need to erase system partition first or something or use some other method like renaming to Update.zip and doing it through recovery and a SD card?

Also, how do I downgrade to 4.2.2 if needed using those files? I imagine I would then need to flash all 3 partitions: system, fastboot and recovery, for it to work but my question is how?

I've done all of this with another device with a custom recovery partition, but since none exist for this device, I just don't know how to do it using "stock" tools.

Thanks

dell venue 8 3830 running android 4.4.2 rooted...

Now im not sure if this will work for anyone but i guess its a reasonable try...

I tried rooting my venue 8 about a billion times, and for some reason, when i cleared some apps (one being ota rootkeeper) i rebooted my tab and found i had root. Now, when i reboot my tab i lose root, so i tried something... i reinstalled ota rootkeeper, rebooted my device, deleted ota, and rebooted again, and bam! I had root access. All i did was that and opened apptoid and installed an app and an su popped up, i had had su installed when trying to use rootgenius but it didnt completely root. So now if i reboot my tab i lose root but if i do the ota thing i regain it... please leave some feedback on how it works, and happy rooting! :laugh:

Does fastboot still work? What were you doing that made adb stop working? Have you revoked the adb authorization yet, also have you gone under settings / storage the click the three dots in the upper right and switch from mtp to ptp then back while USB debugging enabled, you haven't made any build.prop changes have you?
[Dell Venue] p3DRu:
I could never access for fastboot ... I was trying to install an recovery.zip but unsuccessfully , gave error and everything went as it was, nothing has changed ... I think it was coincidence USB debugging crashing ... I'm not even see what happened to this happens . Can you give me a link to the tutorial and files to connect with fastboot to test?
[Dell Venue] social-design-concepts:
How did you root if fastboot wasn't working? what do you see under windows device manager with adb debugging enabled?
[Dell Venue] p3DRu:
Windows does not recognize anything if USB debugging is on , and I just did this tutorial here and the root worked with debugging turned on UBS and the tablet connected . For fastboot connection works no need to be connected and USB debugging ?

im wanting to root my gf's V8 wifi running 4.2.2 v1.32 but i have a few quick questions if you dont mind indulging me.

first, should i just update it to 4.4.2 and then root or root and then update maybe? i told her previously to not update it since i saw people were trying to root the Venues and if she updates it we might not be able to get root. now that there is root for 4.4.2 is there any reason to stay on 4.2.2? the constant notification saying "System update downloaded" is a bit annoying.

second, rooting with this tool wont delete any app data or anything correct? i dont think it will but i just need to double check so i dont screw up any games she has and get my head torn off or anything like that.

thanks for any help

I would probably review what people think of KitKat before making a decision of updating. But in either case the root method should have no effect on any installed apps / personal files.

Take this as no offence I don't care what adb commander has to say. .

What I need to see is a screen shot of the windows device manager while your device is booted into android and one while your device is in charge mode ( we went over that earlier ) and one while your device is manually booted into fastboot / droidboot mode and one while booted into recovery.

Being that adbd is located in ramdisk and it works in Charge Mode ( COS ) I'm also going to need to see your build.prop
