Lost root after 4.1.2

I was running stock 4.1.1 rooted with NO cwm and I accepted the OTA undate two days ago. Now, I have SU still installed but nothing can obtain root permissions. I used Wugz toolkit to reflash su binaries through TWRP a few times and still no dice. Any thoughts?

Welp, I've never actually used adb to push anything manually myself, but now is as good as time as any to try it. The link to CWM on that page is dead. Where else can I get it?

You can download the Touch Recovery on the right side for Google Nexus 7 version. But make sure when you put in
Code:
fastboot flash recovery recovery-clockwork-touch-6.0.1.0-grouper.img
for step 5. instead of what they put.

Every time I reboot into recovery from the bootloader after flashing any recovery (except stock), it fails to boot into recovery. What happens is it shows the Google/Unlocked screen for a couple seconds, goes black (this is where it should enter recovery), but then shows the Google screen again and boots normally. I have tried this with two CWM recoveries and a TWRP recovery, both plugged into a computer and not. when flashing recovery it says OKAY. It seems as if something has gotten corrupted.
Before updating to 4.1.2 everything was working. To get the 4.1.2 update to install, I had to revert back to stock recovery and also revert back to the stock wallet app. Now 'su' is still a command, but it does not do what it is supposed to and no apps have root.

You can just root again and you will have root access.

I lost root too, so I just opened wugtoolkit and hit root. no unlock needed so no loss of programs either.

Any news about this. I stay in the same problem.

Here's my experience:
Stock ROM, rooted, custom kernel.
Got the notification for the 4.1.2 OTA update, so I did a nandroid backup in TWRP. Then I flashed back to the stock recovery and boot.img.
I was thinking that I might lose root, based on other's problems. Looked into installing Root Keeper by Voodoo. In the description it said the same feature is built into SuperSU. Problem was it's built into the paid version, which I didn't have (discovered this after it was too late). Installed 4.1.2 OTA. I lost root. My bootloader was updated to 3.41. I also was not able to flash a recovery. Fastboot flash would not work, Wugs toolkit didn't work. Tried several methods. After reading several threads that have been pretty active for the last few days, here's what finally worked for me. Found it in another thread, which I can't find at the moment.
adb reboot bootloader
fastboot flash bootloader bootloader-grouper-3.34.img from the JRO03D factory image
fastboot flash recovery TWRP img
fastboot reboot-bootloader
TWRP recovery started up :laugh:.
flashed SuperSU to re-root, it was sucessful.
updated busybox binaries.
installed OTA rootkeeper, so hopefully this won't happen again.
I'm not really sure I want to try flashing the 3.41 bootloader.
What a pain in the A.
Now it's time to flash faux kernel.

So, the bootloader 3.41 is the problem?

Would that image work ok for Galaxy s3? Or there is no difference at all, just matter the 4.1.2 android version?
Cuz i updated my device throught Kies (cuzz from the device itself it didnt allow, stating that the image has been modifyied :angel: ) and after that even with the persistent mode on Super SU the root is gone

[Q] Recovery boot error

I used FreeGee to try to install a custom recovery after root. First TWRP, stuck at performing action. Then CWM. Then the older CWM. Always stuck at performing action. The old CWM worked. Reboot to recovery and get security boot error. Looked around on forums and found a CWM batch install that everyone says works for them. Still recovery boot error. Anyone know what's up? I'm on AT&T D800. Rooted by ioroot25
Also RomManager says I have both recoveries installed. Thinking this might be the issue. How do I delete one or both and get on the right track?

I think I have the same problem. Could u solve the problem?

no you can't get recovery on kk because they patched our recovery/loki exploit on kk bootloader

Seems you haven't installed a custom recovery yet buddy, if you tried, you've failed.
First root your phone, then install a custom recovery, then try again booting into your recovery.
If your already on stock kk, I don't believe you can install a custom recovery yet, only root it. So you would first have to downgrade back to JB.

Well there only 2 options really, I'd say TWRP is more user friendly, so i would recommend that to you, before installing a rom first read the instructions and make sure they haven't first recommend a recovery for that specific rom installation.
Once you have a custom recovery its very simple to switch between them.
Follow the instructions here: http://forum.xda-developers.com/showthread.php?t=2469995
It's an old method but is very easy. This will install twrp but an old version.
So before using the method above first download the latest twrp onto your phone, i don't know what version of the g2 you have so if you reply i can try point you to the latest, but if you search for twrp 2.7 for your phone you should find it. You want it in .zip format.
So after saving the file to your phone, go ahead and follow the instructions above, if it says it successful, try booting into recovery again, the same way you managed to format your phone but this time it should boot your recovery, then press install .zip and flash the latest twrp.
Then your ready to go! just follow the instructions for the roms you'd like and flash them.
Best of Luck!

Help with AT&T LGG2 .. stuck in mud

Problem: Can't boot into OS on my D800. When booting the screen stays at LG logo and LED keeps flashing green and blue.
Hisotry:
1) Had original AT&T D800 not rooted, no recovery. Got OTA upgrade to Lollipop.
2) Got new phone so decide to debloat to give phone to my wife (on T-mobile)
3) Read xda forums. Downgraded to d80010o using LG flash utility. rooted. installed older version of twrp using autorec. now phone won't boot but can get into download/twrp
4) got into firmware download mode and flashed d80010d using lg flash utility. this time copied new twrp on sdcard and stripped version of rom (http://forum.xda-developers.com/att-g2/development/rom-stock-lollipop-30b-stripped-t3144195) along with dorilp kernel
5) went back to twrp. flashed stripped rom and kernal.
Still no dice. Exact same situation. I can get into download mode/twrp but when booting system gets stuck on LG logo with led slowly flashing.
what am I doing wrong ?

Are you able to get into recovery? With a lolipo ROM you have to download KitKat boot stack or simply download blastgator lollipop ROM patch from here http://blastagator.ddns.net

From what I read in the OP of that ROM, you're supposed to just flash the rom zip, boot up, go back into recovery and flash the kernel.
"To install ROM, just flash the zip! (Note: The zip isn't signed.) My zip flashes everything you need for the ROM to work correctly.
Recommended: Flash @dorimanx kernel after install. My zip includes stock 30f kernel."
Maybe that's the problem?
Click to expand...
Click to collapse

okay.. installed the patch. still no dice. still getting same stuck at LG logo with led flashing.
also dorimanx kernal is installed. still getting the issue. btw i am not married to this ROM. Any AT&T rom will work. I think there is some mismatch of bootloader/kernal/rom and what not.
what things I can check ?

pulling my hair out.
whatever rom I install using twrp it gets stuck on LG logo. i think i see some message about not being able to unmount /system (but rest of install succeeds).
only way I can get back in OS is to use LG flash utility and flash d80010d or d80010o which basically wipes away everything (recovery, root etc).
assuming I am on stock d80010d, can someone please give idiot proof step by step direction (do i need to check modem version/baseband/bootloader/radio/recovery versions or something to make sure it is compatible ?)

yes I do ..

Ok flash back via tot to kitkat and take ota to lollipop. Then use autorec v2. *Do not use the twrp thats comes autorec as it does not flash roms* flash a BUMPED twrp using twrp. Then install your lolipop rom then afterwards install the dormainx d800 lollipop patch just for safe measure but it should work without flashing it.

thanks for suggestion.. but once I take LP OTA, how will i use autorec ? I thought LP can't be rooted and custom recovery can't be flashed.
also all I can find is Autorec not autorec v2.

Yeah it can be rooted. Download stumproot and install it, follow it thru the steps and do the brute force root. Takes a few minutes but it works. I've done it on stock a couple of times. Get autorec v2 on playstore.

i just read that stumproot is not supported anymore..

Actually instead of stumproot, use srk tool to root stock lollipop. I have had success with that.

How can I Install CM in Bootloader Mode?

Until today I had the impression that my LG G2 was done.
You see, a year ago I had this problem with an update, I carry the phone to my carrier as was under warranty, the Fixed the problem but after that I couldn't boot in recovery mode.
No Power and Volume Down or Up Working, nor the 3 times power combination and then I've just came across this boot into bootloader instructions that I didn't know about it.
Code:
Bootloader: With the device powered down, plug in a USB cable while pressing Volume Up.
Which works like a charm.
So can somebody please point me in the right direction to Install CM13 in bootloader mode?
Best regards

you can't, you can only flash a stock rom in download mode

Maybe I could Install a Stock ROM that comes with a recovery and then install CM, plausible?

steps are like this.
you are on KK, you need to search for files as that variant i dont know..
you must root phone and install custom recovery
so cehck here for root..
http://forum.xda-developers.com/showpost.php?p=63327417&postcount=4
when you rooted. then proceed to install twrp. use the same link above and look in recovery
click on recovery.. remeber you are in KK so use the one for kitkat dont use Lollipop.
when you find recovery install it..when you have it installed. update it with this one
2.8.7.3
http://forum.xda-developers.com/lg-g2/development/twrp-twrp-2-8-0-0-kernel-f2fs-tools-t2898705
install bootstacks for your variant. 5.02 KK bumped.
http://forum.xda-developers.com/lg-g2/development/lg-g2-bootstacks-t3173715
then you need to find a flashable rom in zip format.. for d805. lollipop. once you flashed it and are in stock lollipop
then find root for lollipop use the links above , i thnk theres root for LP.
when roo is rooted then go to playstore and download autorec for lollipop for your variant..
install and install twrp.. update it with 2.8.7.3 thermal one..
then install hybrids bootsacks. for your variant
http://forum.xda-developers.com/lg-g2/development/boot-g2-hybrid-bootstacks-t3183219
when installing hybrid.. reboot from recovery into recovery again to take effect ... then flash rom and gapps for cm13.

Already rooted. Will check the instructions, overall the one about the recovery...as I said before I don't have a recovery options, when I install TWRP and try to reboot into the recovery mode the phone just reboot.
I believe you gave me the instructions to fix this, fix the recovery, will follow your instructions and will be back.
Thank you for your time.

If it doesn't work try to install the stock kk again and do all the above process again
