[Q] Trouble when trying to install CWM/TWRP - G2 Q&A, Help & Troubleshooting

Hi everybody,
I've installed KitKat 4.4.2 via OTA last saturday. Now, when I try to install a recovery (CWM or TWRP) in my D802, I get problems.
First of all, I rooted my device with ioroot25. Then, I installed ROM Manager, downloaded CWM Recovery (non-touch), reboot with recovery. It starts "Android system recovery <3e>" instead of the cwm.
Same problems with TWRP.
I tried also to install the recovery via adb, but nothing. When i try, the cmd shows and error: Failed to open aboot for reading.
How can I resolve?
Thank you very much
Dan

lost root after 4.4.2 upgrade, cant re-root

hello guys,
I had 4.4.1 rom+kernel stock, rooted and custom recovery, after the OTA to 4.4.2 lost my root and recovery.
tried re-root with wug's but it gets stuck on "pushing root file to you device".
got superSU application but cant remove it because its system application.
Is there a way to root it?
thanks.
Same here except i had cwm touch latest. It seems i have lost my recovery too. If i try and boot into the recovery menu i get the open hood android with a red triangle.
No custom kernel only custom recovery.

I lost my custom recovery too. But I just reflashed it (adb reboot bootloader, then flashed a downloaded custom recovery via fastboot), and then reflashed SuperSU as well.

I'm having the same problem. Root undone, and recovery went back to stock. Custom recovery doesn't stick after reboot.

I was in the same situation after my OTA of 4.4.2
I had nexus root toolkit, tried to put in twrp with it failed.
Then updated to the latest nrt and then I could flash the latest twrp, havent tried cwm.
and eventually got the root back using nrt

Found the solution to my problem. Used CF Auto Root instead of manually flashing SuperSU again. Cheers guys!

Same thing happened to me. just use fastboot to flash CWM, then before you reboot go into the recovery. then next time you reboot it will still be there. For some reason if I flash the recovery then reboot without entering recovery it will loose the recovery.
Once you have the recovery back, just flash the SuperSU binary through CWM.
Also, IMHO, dont use toolkits... you dont really know whats going on when you use those. Learn to use ADB & fastboot. They are really simple to use and you will be better able to help yourself when you have problems in the future.

how to root and still have stock recovery using adb

for rooting i usually uses the wugfresh nexus toolkit and it will root the nexus by using a temporary twrp recovery but how do i do the same using adb?
im using linux now so thats why i used adb to flash 4.4 but i couldnt find a way to flash twrp temporarily(the recovery will only last for one time and returns to stock afterwards) . i could flash twrp and install superuser and then flash the stock recovery but im just trying to figure out how the toolkit does it by using two steps (flashing twrp temporarily and installing super su).

The command should be fastboot -c "lge.kcal=0|0|0|x" boot nameofcustomrecovery.img , with this command you can boot in twrp temporarily
Or simply flash the stock recovery when done.

Try framaroot maybe? There are reports it works on KitKat..

Upgrading TWRP and Root Problem

So basicly I just want to upgrade my TWRP version (from 2.6.3.2 to 2.6.3.3+) in order to flash new kitkat roms.
But I have 2 issues:
1) I have rooted my device and installed TWRP 2.6.3.2 on my LG stock rom, then I wanted to change rom, so I wiped all but internal storage and flashed Beanstalk 4.4.2 + GAPPS. Now it looks like there's a problem with my root access (root checker says that there is a problem and superSU won't install binary updates). Recovery works fine. Do I need to root my phone again or what? Can I just do these steps: http://forum.xda-developers.com/showthread.php?t=2448887 all over again?
Edit: Ok, After flashing http://download.chainfire.eu/376/SuperSU/, I just needed to deativate supersu and reactivate it. Now it works just fine!
2) I wanted to upgrade my TWRP using FreeGee, but it looks like the app couldn't load without root access (Issue 1). So can I upgrade it with just doing these steps: http://forum.xda-developers.com/showthread.php?t=2449670 all over again?
Sorry for the long questions.
Thanks
Download the zip file for twrp. Boot into recovery and install the zip

[Q]LG D802 4.4.2 TWRP Not Opening

Hello I need help about an Android app called "AutoRec". I have rooted my LG G2 D802 4.4.2 with IOroot but I did not get SU app so I downloaded one from google play called "SuperSU" and I have checked and it says my device is rooted properly. I wanted to do a EFS Backup just in case so I started searching how to flash a custom recovery image. Luckily I found AutoRec and done it as instructed. But when I enter recovery mode from my phone it shows the standard stock LG recovery instead of TWRP 2.7. But after using the app again and tapping go to recovery from the AutoRec app after finishing I could use TWRP but once rebooted, it does not enter TWRP again when I try to enter to recovery mod, instead it shows the stock recovery. Can any of you help me please? Thank you.

reboot

How To Root A G2 That Has TWRP Installed?

How to Root a G2 which has TWRP installed?
Hi there!
I'm a beginner and I would be grateful if you could help me with this.
While trying to install CyanogenMod, I rooted my G2 using ioroot and then install Autorec. At this point I made a mistake and recover KitKat stock with Autorec, loosing root privileges. Now when I try to root using ioroot, the device shows me the TWRP menu.
I am stuck here. How could I root and install CyanogenMod????
Thanks a lot!!! Please let me know if this is not the right place for asking this in the forum.
Hi,
I think you can download flashable SuperSu and flash it via TWRP.

Hi @TwinHeadedEagle, thanks a lot for your reply. I installed SuperSu through GooglePlay, after being installed it requested to make some modifications through TWRP, which it successfully did. At this point I was wondering wether I actually had root access or not to my device, so I decided to install Root Checker. This last one says that 'Root access is properly installed on this device'.
So I guess that I am root and I can with 'Installing CyanogenMod from recovery' as it is showed at https://wiki.cyanogenmod.org/w/Install_CM_for_d802.
Am I right?
Root is not required to install CM, only a custom recovery.
I have a d802. It was running stock Lollipop with no root. I installed a custom recovery (TWRP) and was able to flash CM12.1, Cloudy, and Orion.

Congratulations! Right now, I am using Inazuma on a d802 and it's great.

Thanks @audit13! At first I was exceptional about using customs roms, but It certainly has given new life into my D802. I find very sad that companies do not work for keeping our devices updated, It is a way of planned obsolescence. My D802 has more than enough hardware for what I use it and now that I have managed to update it (without the help of LG) it is like having a brand new phone!
Thanks to all the xda-developers community!
