Hey social-design-concepts,

Just an update on my 3840 8" Tab and the bootloop issue.

After following your steps and reading various forums I still cannot fix the issue even after reversing root process (must have been something I have done after rooting). The behaviour is really odd after every reboot it bootloops - I wipe data and it works until next boot :( Regardless, I don't want to fix it anymore (even if I did I wouldn't feel confident with it - bad mojo lol). I really just want to flash OTA without voiding warranty by adding unsigned kernel. Is there anyway I could do this? The dell instructions will work but if I encounter a hardware issue or something is wrong I will face trouble. Any ideas just want to Flash OTA - here are instructions by Dell - http://opensource.dell.com/releases/Venue_8_3840_Merrifield/developer-edition/Doc/OSS_A150&A195.pdf (I assume fastboot simply flashes OTA with kernel that is unsigned?) Could I obtain a signed kernel anywhere?

Sorry for this trouble I know it extends past the scope of the root software but at this stage I just want a working tablet back. If you would like to speak to me directly as well PM me.

Thanks so much for your time and for the software.

Acer Iconia A1-830 rooted - Need Kitkat SD card fix

I found a Youtube video of someone that rooted their Acer Iconia IA based tablet. I was able to do the same to mine without any rooting issues. I mainly wanted to root my tablet in order to move apps from the internal SD to the the external SD card. Here is the link: https://www.youtube.com/watch?v=Ye8OW997Ieg

For the SD card write fix I tried a few apps that modified the platform.xml file and I can see this happened:

1. Using a root-enabled file manager, navigate to /system/etc/permissions

2. Edit platform.xml and find the WRITE_EXTERNAL_STORAGE permission.

3. Add an additional group definition for this permission...<group gid="media_rw" />

But after reboot, when going to the "apps" manager on the tablet, there is no option to "move to SD card". I have a MTK Kitkat phone and after the bug fix I can see the option to move most 3rd party apps to SD card.

I found that some Samsung devices need:

READ_EXTERNAL_STORAGE with the <group gid="media_rw" /> permissions

I am able to manually edit and safe my platform.xml file and have this line added too. But still no option.

And finally, there was a note to change permission on the "media rw" directory itself to 777 or equivalent. This did nothing.

Does this have to do with something related to the Acer OS overlay commands? Or the IA based tablet? Or did something really work for me and I am not looking in the correct place? Any comments are welcome.

same problem

hi im having same problem, can i get instruction on how to solve it?

---------- Post added at 10:37 AM ---------- Previous post was at 10:33 AM ----------

hi there,

im having same problem with you, do you have solution yet? im using b1-730hd.
[Dell Venue] vampir74:
Use repair tool for b1-730hd

Sent from my B1-730HD
[Dell Venue] Kentan95:
after i connect my tab to the laptop, the bar below the usb sign turns from white to red. my repair process stuck at 5%. my driver are correctly installed, i have system.img in the sd card. i think my laptop cant detect my tab yet because the sound is like connecting and disconnecting continuously. i cant do the repair progress . what should i do?
[Dell Venue] Antagonist42:
Are you using USB 3.0 port? Unless it's been upgraded on production try using only USB 2.0

Number of USB ports in use? Try to keep this to only the Tablet/Handset.

USB Cable length : use shortest you can (OTG recommends 15cm).
[Dell Venue] Kentan95:
i managed to repair, over the night i managed to get into the charging logo instead of usb logo. as my tab goes into recovery mode in loop, when i reboot it, i shut it down manually before waiting for it to go into the loop and goes back to recovery mode, and when i plug usb in, the charging mode appear but although i have repaired, it doesnt help at all, it still stuck in the loop.
[Dell Venue] GeeKerGurL:
Hi SDC. Not trying to rush or anything but just wondering if you still plan to release this soon? I would like to try it myself. Thanks!

Yeah I'll have something up today , im just trying to resolve an issue with the original trigger as i would like to not have to put up another one. later . .

Bad news on Acer A1-840FHD, with the latest OTA the bootloader is upgraded and the OEM command used by SDC doesn't work anymore :(

[MENTION=4821597]social-design-concepts[/MENTION] I didn't upgrade my tab, so let me know if we can do something to dump the firmware ?

maybe DD should do the trick on the right partitions

and I can also try a CWM backup
[Dell Venue] vampirefo:
He should try the other two triggers, the last one seems to work on more devices, trigger 1 which is used in the pic you showed only works for a few devices.

Still Have to make the new thread but here is the windows standalone cwm launcher

Intel Fastboot Tethered Recovery Launcher IntelAndroid-FBRL.7z

fixed backup / restore from internal sdcard

fixed restoring /system partition

adb sideload of update.zip is still broken

if you want to try this on jellybean you'll need to update the recovery.fstab in the recovery.zip for your devices

support fastboot oem triggers are :

T1 oem startftm ( very few devices support this command , but its the original used so )

T2 oem backup_factory ( limited devices support this command )

T3 oem stop_partitioning ( should work on alot of kitkat builds )

i'm not including any device drivers so you'll have to make sure you install them your self new thread coming soon. . . .

make sure you download UPDATE-SuperSU-vX.Xx.zip and place it on your internal or external_sd the install it through the install zip /option in CWM

This doesn't install a permanent copy of CWM Recovery on your device this is a temporary CWM Recovery Session it has to be launched from a pc ( thethered ) each time you need to access the CWM Recovery.

[MENTION=2472806]vampirefo[/MENTION] the new recovery binary you sent wasnt mounting external_sd ? the old one is mounting it fine now but would be nice to have the heading changed. . .
[Dell Venue] vampirefo:
[MENTION=4821597]social-design-concepts[/MENTION]

Yes, install zip from external sdcard choice is removed when adb sideload option is removed, they are the same condition, backup and restore from external sdcard would still work though.

Leaving adb sideload option on recovery restores choice of install zip from external sdcard.
[Dell Venue] zardoz2112:
no dice

Well. as far as MY iView i700 is concerened...this did not work. T1 was the same as previous results, T2 I THOUGHT had it, but neither SU or CWM were there after reboot. Same with T3. I would like to think I missed a step or something simple. Maybe a more knowledgeable soul around these parts can clue me in. Otherwise, I await the thread with baited breath.
[Dell Venue] social-design-concepts:
guess ill test the iview now brb .
[Dell Venue] social-design-concepts:
since i don't intend to keep this one rooted im backing it up now then will install su try to install supersu from the playstore ive tested a couple that wouldnt install the apk to /system/app but installed su in xbin will will update in a second im using T3

option t3 works just fine on my daughters iview i700

recovery isn't permanent it's a temporary CWM Session you have to restart it from the pc each time.
[Dell Venue] vampirefo:
Linux version works like a dream, I don't use windows so can't comment on that version.

Yes, trigger 3 is what I used as well for iview i-700.
[Dell Venue] sfleury:
I would suspect it is a 4.3/module compatibility issue, there are many modules and they come from many sources, and they all run with priviledge so there is always a potential risk with them.
[Dell Venue] social-design-concepts:
if i under stand correctly xposed uses the aosp hooks for things and then changes it in memory to add features like what you see in 3rd party roms is that the basic basic idea of how it works. if so i could imagine framework diffs between 4.2.2 and 4.3 causing issues.
[Dell Venue] NOTdevelopers:
How to install? yes.

1. open part1 xfstk.bat

2.plug your device

3.push Power button

4.waiting....

5.rebooted droidboot.

6.open part2 flash.bat

maybe done?
[Dell Venue] social-design-concepts:
possible one step graphical process coming.

works busy so no idea when ill get around to better instructions was hoping to use my quad display at work to make writing them easier but the whole process might change to use the graphical tool i forgot at work friday instead of the batch files i need a user that is already comfortable with the batch process to test this should make it a one step process outside of installing the drivers. so it should have better success for users having issues installing.
[Dell Venue] joanthanmajh:
did you encounter the bootloop after activating modules, and did you get out by flashing the zip provided by the author?
[Dell Venue] ns218:
I get the boot loop after just installing and activating the framework. To get out of the boot loop tapping a hardware key a few times while the tablet is booting will disable the framework, allowing the tablet to boot up normally
[Dell Venue] darklordofthesith:
Yep. Thats the same thing that I was saying before. No modules but the framework would hang and I had to hit the hardware button 5 times to get it to boot normally.
[Dell Venue] saintii2:
I tried installing in recovery, safe mode, and regular way. No dice.
[Dell Venue] social-design-concepts:
I wish I could help debug what's going on its hard to do with out having the device hopefully dell will release the v7 dev files sometime this week.

could it have something to do with ia_watchdog? On 4.3 outside of xposed any other hang ups besides the backwards compatibility support for sdcard?
[Dell Venue] saintii2:
What is ia_watchdog? It appears that editing build.prop doesn't work either. The changes don't stick after reboot.
[Dell Venue] social-design-concepts:
I think I'm off based on that after all.

I'm gonna unpack the boot.img and see if I can get the sdcard issue addressed after my daughter goes to sleep if someone what's to test tonight. I'll start searching for what is causing the write issues might to be some kind of protection in the boot image. Probably the same thing causing the xposed issue.

Are the users using the original jcase root seeing the same issues or just the dev edition users
[Dell Venue] kairnage:
I haven't had a chance to test the changes to the unpack tool, but the first thing is the default.prop in the boot.img needs ro.secure=0. That should fix the edit issues. I don't know if it will fix the bootloop when you try to push the files. But it's only the system files like the prop and init files. I was able to push the deodexed system/apps and framework files with no issue.

This is what these should be:

ro.secure=0
ro.adb.secure=1
ro.debuggable=1
ro.allow.mock.location=1
[Dell Venue] social-design-concepts:
That shouldn't be what is causing the write issue but I'll make those changes for you I just laid her down so I'll pm you a link for testing in a short while I gotta run over to a buddies quick and help him out with something first.

You should also be able to push a default.prop to the root of /system with those changes and and correct ownership an permissions via adb and based of how prop files are handled should use those ro. over anything in /default.prop google android .prop one of the links should explain the hierarchy of how android prop are handled I didn't know this until I googled why /data/local.prop was removed.
[Dell Venue] saintii2:
I changed those values and it wouldn't boot. Had to go into safe mode to boot up again.
[Dell Venue] kairnage:
Where? The only place you can change them and have any affect is in the boot.img.
[Dell Venue] social-design-concepts:
It took me a bit to get unpacking with the old tools on my git and repacking with the dell tools to work correct I have a v7 softbricked so I'm not trying to package a image to boot all the way to android but I've been able to get it to boot with those changes just can't get past device offline I need to build a simpler ramdisk for my purpose.
[Dell Venue] kairnage:
Cool I will be bouncing between PCs for the next couple hours. I had a guy just show up at my door holding his PC. Never even met him before, Small town, LOL
[Dell Venue] saintii2:
I tried editing the build.prop file to see if it made a difference.
[Dell Venue] social-design-concepts:
Google it you should be able to have a default.prop under /system

default.prop is checked first any ro. Changes made if prop files that is read after default.prop should overwrite the default.prol values when its read to memory on boot up.
[Dell Venue] kairnage:
OK yeah, it won't hold there even if the edit stayed. . The default in the boot.img controls those. It's why even if you can edit the default.prop, it resets after reboot.
[Dell Venue] social-design-concepts:
when i get the new thread up i'll either have a script for each trigger or a simple menu.sh to launch the triggers wanted to make sure the launcher worked first. . . ive tested it now on the Dell Venue 7 3730, Iview I700, and the Kurio Xtreme ,

It works fine on the iView i700 option T3 make sure you download UPDATE-SuperSU-vX.Xx.zip and place it on your internal or external_sd the install it through the install zip /option in CWM

tested restore too it works just fine .
[Dell Venue] zardoz2112:
no su

Yeah, tried to install supersu from playstore after I thought T2had done the deed, but it told me binary was not there. I know it's so close....it's making me NUTZ!
[Dell Venue] social-design-concepts:
you have downloaded the recovery install of supersu ?
[Dell Venue] zardoz2112:
I grabbed what you posted tonight maybe I got the wrong one? I was trying to pu my kids to bed simultaneously.... Where's the one I want, then?
[Dell Venue] social-design-concepts:
You need what I posted and the supersu installer they're both linked on that post now.

The RecoveryLauncher only start a temp CWM Recovery Session you then have to install the supersu zip through the recovery session.

but i'm off to bed now going to start the new thread on lunch tmrw. good luck and good night .
[Dell Venue] zardoz2112:
Got it. I will take another stab at it in the morning.. Appreciate your patience and kind assistance.

[Dell Venue] quevon24:
I found how to do it on previous replies with this commands:

adb reboot-bootloader

fastboot flash system Venue_8_WiFi_JB4.3v1.25.system.img.gz

fastboot flash boot Venue_8_WiFi_JB4.3v1.25.boot.img

fastboot flash fastboot Venue_8_WiFi_JB4.3v1.25.fastboot.img

fastboot flash recovery Venue_8_WiFi_JB4.3v1.25.recovery.img

fastboot erase userdata

fastboot erase cache

but i was wondering, for what are these files:

partition.tbl

image.list

ifwi/ (folder)

Thanks. And also, how can i disable automatic ota updates? to avoid to update to 4.4
[Dell Venue] social-design-concepts:
Originally I had planned a flash script for myKIT_BATCH which is what the image.list file was for it defined the image names a kind of manifest so that was a file added by me.

partition.tbl is what it says its the partition table used in the process of partitioning the emmc

Ifwi contain the actual firmware for the device basically its the bios / efi if you really had to compare it to something but its not really a bios or efi so really firmware / bootloader is the best term for it.

[Dell Venue] social-design-concepts:
Unfortunately this is a documented issue on the V8 if its under warranty still make a claim if not you can try to charge the battery with an external LiPO charger I can't remember if it an issue with the charging circuit on the board or battery
[Dell Venue] vampirefo:
He can return it if he wants, or charge it, then power off, and reboot. Seeing he doesn't want to charge the tablet, might as well return it.
[Dell Venue] social-design-concepts:
Didn't they say after 5hours it never shows the charging animation and just display the battery question mark it was a big issue back in July after the last kk update. COS isn't detecting the battery correctly on some level whether is voltage temp or what else the charging circuit won't start under COS cause the battery isn't reporting correctly so they can't charge it in the tablet. That's why I said if it isn't under warranty try a external LiPO charger before buying a new battery.

A1-830 Bricked?

Can someone direct me to the proper thread or post if there is a solution?

My A1-830 boots to a USB symbol and after a moment the bar goes to red. I was attempting to downgraded my tablet from kitkat to jelly bean while in droidboot and I am certain I specified the wrong image file. I can get to recovery and when I applied the zipped package it say installing system update, then it stays at Wipe data package and reboots on it own with no error message and it goes back to the USB symbol. No matter what button combinations I press I can not get to droidboot. I am certain it is being detected cause I can see it in the windows device manager as a ADB interface but the ADB shell is not communicating with the table.

any issues after rooting g1-725 ?

. Well we are on Feb 2015 my question is in all this months of trying the root on g1-725 did you have found any issues ? Can you download large and big heavy games and put them on the external SD? Can you move your apps to SD and run them with no problem from the external SD? And the most important bro , have you found the original ROM from fabric of this device g1-725? I couldn't found it in gateways support website. Not even the users manual!!

I rooted using this method a while back, how do I clear cache though?

Normally I use CWM or TWRM but this is a bit different.
[Dell Venue] dawgdoc:
You didn't state which device you are on, but you should be able to do this through recovery. Can you boot into recovery using the hardware keys? If your recovery doesn't allow you to clear cache, check post #2 of this thread. There are instructions there for a tethered recovery that will allow you to clear cache.

Also, a quick search using the keywords: adb fastboot clear cache yielded a couple of commands that may be useful. Keep in mind that I have tried none of these.

The most straight forward non recovery method to erase the contents of the /cache partition is

fastboot erase cache

To wipe userdata and cache from an adb shell

wipe data

The same, wipe userdata and cache, can be done with

fastboot -w

To clear dalvik-cache check your recovery or this thread for an adb method.
[Dell Venue] kt-Froggy:
How about: Settings -> Storage -> Cached Data (tap on it). Also, you can use a bunch of apps available in Play store that have this function (search for "cache cleaner" or "clear cache"). Technically, I think you could just delete the contents of /cache using any file explorer with root access, but I haven't tried that... I know for sure you can clear dalvik cache this way: go to /data/dalvik-cache, and delete all the contents of that folder. Reboot. No need to use a recovery.
