[Q] OTA Update on rooted Venue 7 3740 - Dell Venue

Hi,
I tried to apply the current OTA update on my Venue 7 3740 but after downloading and rebooting I get the red triangle of death and the update is not applied. The tablet boots fine afterwards though so not bricked *sigh*
Before trying to apply the update I uninstalled Xposed framework and did the SuperSU complete unroot option.
An option would be to restore a Nandroid backup to the initial state without root and xposed done via tethered CWM but I would be really glad if I could keep my current setup. On the other hand can somebody confirm the restore from tethered CWM works correctly? I don't want to brick :silly:
Any suggestions/experience concerning OTA on rooted 3740?
Thanks in advance,
slaecker

My rooted 3840 took 4 or 5 times to take the update. I think there was some discussion on this in another thread. Keep retrying, you might get lucky.

I ended up restoring my initial nandroid backup and the update was applied. Now I setup the tablet from scratch.

[Q] Failing to update, reset

Hi all, I originally rooted my phone using this post several months ag http://forum.xda-developers.com/showthread.php?t=2380325
I'm still fairly new to the dealings of root, and have found that I only used it to have access to a couple of cool apps that required root and at that rate I don't even use any more. That being said, I finally accepted the most recent update being okay that I would likely loose my root access. The update kept failing, I assumed because of the root. I backed up my personal data, and performed a factory reset from the phone. The phone still has superuser from the reset and still fails to update. Could someone help me return my phone to fully stock configuration? Thanks!

Find out what odin is. Then..
Google "odin emergency tar (your build number here)" or something to that effect.
If you don't know your build number then you have some more research to do. Good luck.
I'd recommend using the Verizon update assistant. Much easier, but takes about half an hour to do:
1) Connect phone to PC using USB cord
2) When prompted for what action to take when this device is connected, select Verizon update assistant. Installation will take a few minutes.
3) Start the update assistant and confirm that you want to update the phone. The update will take a few minutes.
When the update is complete, you should have the most current update (MK2), and no root access. Should you need root again, try Saferoot - it's quick and easy:

Thanks for pointing me in the right direction guys, I'll do some more research into both and report back soon.
Help! I've researched odin, downloaded and attempted to flash the stock image. Odin failed. My phone as of now is stuck in the downloading screen.

You need to flash the same stock image as what was previously on your phone.
If you don't know what version you were on previously, flash MJ7 or MK2.

Q Confused about rooting vs installing recovery

I rooted my z2 (.167 4.4.4) and then let it update back to kitkat which kept the root (though i cant update supersu).
How would i go about installing a recovery (dual?) now since i missed that step before. would i need to downgrade again?
if so ill just leave it for now as im not going through that process again
Have a look here http://forum.xda-developers.com/xperia-z2/general/4-4-4-sony-ric-killer-t2953141
Thank you I'll check it out when I get back from work.

Dell venue 10 5050 android updates fail after tether root

I have the tablet rooted via tether. An android update came up today. Could not install it. Im guessing its due to the tethered root. So I tried to reset tablet, still no luck with android update. I then unrooted via supersu, still errors on update. I don't know how to do any future android updates. Anyone have any input/ideas? thanks
If you have rooted your tablet, and did not back up those being-modified files, then restore them, definitely the OTA update will fail.

You might need to find a virgin device , it seems that with some devices that ship with lollipop installed updates will fail simply if the partition has ever been mounted rw.
On those devices you have to dd the raw image back to the system partition before doing ota updates.
Not saying its what is going on with yours what's the log say?
im assuming DD has to do with Linux stuff of which I guess I better start learning. I don't have the tablet. Dell replaced it as it didn't boot up. I was lucky. If I only knew what to do a backup, what to backup and what software, etc...I would love to root it again, but Dell has already sent out 3 updates on this tablet. Once I root it, I cant install updates. It reboots to install update, then a android robot comes up on bootup with the dreaded exclamation mark/triangle, stating update failed. I did not keep a log of it. I know windows since 3.1, maybe its time to learn some Linux
Thanks for helping this newbie
:good:

[HELP NEEDED] Bricked Kindle Fire HDx 7' 3rd gen- Sort of, Not really

I had Safetrap v4.01 running on my rooted kindle (4.5.2)
I have a copy of stock rom.
Long story short, I flashed gappz from Nexus v4 over the stock rom.
I still have Safetrap but it is disabled. Root doesn't work on my 4.5.2
And to make matters worse, I had rename the devicesoftwareota.apk to BAK to stop receiving updates. I have ADB yes, but not root. I checked. That's why it is semi bricked but I still have access to the system and SDCARD. -____- help is appreciated but it looks impossible. After taking care of root and stuff all the time, I feel like such a noob Ugh.

Problem solved.
After factory resetting (cringe) I know I know. Somehow I didn't encounter a brick but Safetrap was still installed and I had no home, back buttons ... So I tried the latest Kingroot.. And it didn't work.
HOWEVER thanks to a forum I read up on suggesting to try version 4.5.0 of Kingroot, I now have Root on my 4.5.2 Time to restore my stock kindle without the borked up version
Update: Even after receiving root, I couldn't access Safetrap. It was borked. I removed it, and re-installed. I pushed my backup Stock into TWRP/BACKUPS without deleting anything (just in case) and Restore said it failed but upon booting, I have my home button and back button again. ~ The end.
Hopefully, it helps someone with a similar issue.

How to install an update on a rooted tablet?

I've got a rooted Nexus 9 (WiFi) with TWRP installed. A few days ago I got a notification to install an update. I was surprised, as I didn't think OTA updates would come through once TWRP/root was set up. I tried installing it, but it just gets stuck at the TWRP logo.
I'm guessing that you can't just install OTA updates, so I have two questions:
1. How can I install the update (without losing all my data)?
2. If I can't install the update, how do I get rid of the "System update downloaded" message that keeps showing up?
It's been a few years since I've been in to this kind of stuff, so forgive me if these are dumb question
Thanks!
If your using systemless supersu and have an unmodified/untouched system partition then Flashfire app, maybe able to apply the update.

Otherwise you will need to flash factory images (which can be done without wiping data) to update.
