[Q] Lenovo A820 - Lose root after update to S149 - General Questions and Answers

Hi guys,
so I bought my Lenovo A820 rooted with a stock S135 ROM. An update came through saying it needed to be updated to S149, and I stupidly updated it through the system without checking first or creating a backup of my current ROM. Now my phone has loads of Chinese apps installed, I cannot use the play store as it says "no connection" and root checker says there are no SuperSU binaries installed.
My problem is that I was hoping to install the Etotalk MOD ROM which they put on their website for sale a few days ago. I should be receiving the ROM from them on Monday, however I cannot install it if my phone is not rooted.
So basically, is there any way I can re root my phone, downgrade it back to S135 so I can install CWM recovery, and then the Etotalk ROM? Any help of suggestions any of you can give me on this would be greatly appreciated.
Many thanks in advance!

[Q] Need help with CWM for Lenovo A830 please!

Hello dear friends,
I just recently purchased a Lenovo A830 due to it being a budget phone but now I am starting to regret it.
It came rooted I checked through (Root Checker) app, but it's mostly in chinese even after changing the language.
So I came across this custom rom recently and I am really interested to install it so I can get rid of the current stock rom.
Unfortunately I need to have clock world mod recovery installed, So I have been trying to install it through Flash tools v3.1304.0.119 -- it wouldn't detect even after installing the proper usb drivers which are ( MTK6589 Drivers ).
It did detect once and it went to a 100% in red and said something about checking the logs and that it wouldn't work cannot be specific about this because it's not doing that anymore it's just not detecting.
Can someone please try to help me and guide me to install or tell me what to do to install CWM on my lenovo A830, It would be much appreciated.
Any help would be really appreciated.
Thanks.

I tried numbers of methods to get rigid of it but still in vain. I tried-
1. resintall from scratch with the stock ROM....failed....still complaining rooted
2. rooted it and deleted all busybox related files, deleted su and unroot it using root software.......failed.......still complaining rooted
3. rooted it and deleted all bushbox related files, deleted su and unroot is using unroot feature of superuser and supercleaner.......failed.....still complaining rooted.
Every time after unrooted, I checked with root checker software and those checker software didnt find any root trace. But, GFE is still complaining rooted.
Please, please.....anyone can help to completely unroot my Teclast X89 so that I can successfully install GFE.
Thanks in advance

[Completed] Can I OTA update a rooted Android L phone.

Hello two days back, I rooted my phone(Lenovo k3 note) with hope to install cyanogenmod on it. :crying:! its not for mine.
I used Lenovo k3 note manager to root it, and it also installed TWRP recovery.
Today I came to know its about to get Android Marshmallow update next month. Can I update it when its available?

Hi
You need to be on the stock recovery to get an ota update. If you try to update now it won't work so you now need to flash your stock firmware before you do it.

[Completed] OTA Updates after Root

Hi Guys,
i have some questions concerning rooting. I have a stock Galaxy S7 (SM-G930F) with T-Mobile branding. I would like to install a Custom ROM because my battery life is so bad but i love this phone (for example because of its water resistance and the fact that my hobby is diving ).
So my plan is:
1. root my device and install a custom Nougat ROM (to change the screen resolution)
2. when the official update is out i want to go back to stock Firmware
3. now my question: Is it possible to receive OTA Updates after getting back to stock firmware?
I know know is set to 0x1 after a root and im going to lose my varranty but thats no problem, i would only like to receive OTA Updates after going back to stock firmware.
Thank you for your help!
Greetings from Munich and have a great new Year 2017
Hi!
As long as your device is stock, recovery included, you should receive the ota no problem. So flashing stock firmware and recovery should do the trick. :good:
Don't accept an ota if you do happen to get an update notification, if you are not completely stock. It will fail.
Last resort too, is flashing an updated version manually. If that's possible for your device.
Good luck!
I posted i thought but don't see it i rooted an LG ls675 with king root removed a couple preinstalled apps sprint zone and 2 amazon apps I mistakenly tried ota failed found out this unrooted my phone and tried another ota that failed also running stock installed a root browser titanium bu busy box ect do i need to remove these apps or will i have to do factory reset to get this update running 5.1.1
