hey i have this issue on att g3 installed twrp through auto rec now boots to security error screen. how can i fix this?

Since you have twrp just flash a kernel or a new rom through twrp.

Cool thanks man. I was kinda stuck there. I couldn't get my pc to see the phone, had to wait for a micro sd card to put the kernel on. Thanks a lot

LG G3 LS990 - ZVB - Rooted + TWRP - Flash Stock Recovery Only
Hi, I am looking for flashing stock recovery on my LG G3 Sprint LS990. I believe the same method will work. I am currently running on stock ZVB ROM rooted and TWRP installed as recovery. In the download folder for LS990-ZVB http://downloads.codefi.re/autoprime/LG/LG_G3/LS990/stock_partitions/ZVB, there is no recovery image file, but in ZVA folder there is. I am just wondering if I can flash ZVA folder's recovery image using Flashify to my ZVB ROM LS990 and if that will work.
My LS990 is rooted and currently have TWRP. i get secure boot error when the phone reboots after accepting Android updates installation that come automatically. I believe installing stock recovery will resolve this issue and allow to install Android updates I do not want to going back to stock completely, that will unroot my phone and again I have do all these staffs.
Anyone can help to advise, will be appreciated. Thanks.

Worked for me
It's not english, it is portuguese Brazil, but it works.

TWRP install on G4 H815 20A mm, doesn't stick (unlocked bootloader by LG official)

Hi,
I get TWRP running on phone , but when I boot into recovery , I always get the Standard Recovery, only option being a factory reset. Have opted for this factory reset and that is exactly what I get, no TWRP :crying:
Thanks

Also if you reboot to recovery through TWRP itself, it won't stick? If not: Is rooting an option for you? If yes: Try Flashify and flash it through this nifty little app .

More than one way to skin a cat. went HERE chainfire Systemless Root 2.61 using Running TWRP from PC

This happened to me, too. Here is what i did:
Boot your device into fastboot mode via adb, straight up boot to recovery ("fastboot boot twrp-2.8.7.0-h815.img"), transfer the recovery image to your device, then flash it from within TWRP (there is an option for that within the normal install menu, its called "install image" or something like that). Hope this helps, it did for me.
Edit: Just realized you already found a solution. Never mind.

Ive the same problem. I unlocked the bootloader by the official procedure. Then i tried to flash twrp but it doesnt install truly. It always appear the stock recovery. I tried also clockrecovery but nothing. No recovery wants to get installed. Pls help me i want a custom rom on my g4

use twrp v2.8.7.0 on 20A mm....... adb reboot bootloader, fastboot boot twrp-2.8.7.0-h815.img, and to double check you have recovery,adb reboot recovery and then flash STOCK-20a-ROOTED

are you Trying 3.5.2???

Having a similar issue. I'm on 3.5.2 unlocked bootloader, no root, stock recovery. Everytime I try to flash TWRP, it appears to succeed, but will never boot to TWRP. Boots fastboot and OOS just fine, but no recovery available. I then tried to flash stock recovery, but same issue appears. I then was able to use skipsoft toolkit to get stock recovery, but only by relocking then unlocking the bootloader. Everytime I tried to simply flash a recovery it appears to succeed, but will not boot to recovery. So skipsoft was able to fix the no recovery problem, but I am still unable to flash TWRP

Here is the issue. 3.5.2 has a different firmware than previous OOS versions. You will need a specific 3.5.2 modified TWRP. The link is here:
http://forum.xda-developers.com/attachment.php?attachmentid=3875375&d=1473889816
You can see that this is discussed on the oneplus forums here: https://forums.oneplus.net/threads/...ity-update-with-working-twrp-recovery.465353/
I ran into this same problem myself, and realized that this was the issue. You should be very careful because it could cause you some grief. Whatever you do don't lock your bootloader if you end up with a nonfunctional and non functional recovery.

I have the same issue i can flash all the recovery images but non of them worked i tried 1000 different methods and nothing works.. Getting a bit desperate is someone please able to help me got my new phone already broke it kinda..

Follow this guide and everything will be ok.

I know u fixed the problem but i think this is a general guide to fix your phone if you have this type of issue after flashing OOS 3.5.6 based roms!
i had the same issue yesterday with freedom os 1.7 (based on OOS 3.5.6) and OOS 3.5.6, here is how i fixed my phone:
- download http://forum.xda-developers.com/attachment.php?attachmentid=3875375&d=1473889816
-unzip it and put it on the desktop
-put your phone in fastboot (make sure you have unloked bootloader and installed all the drivers and adb on your pc)
-press shift and right mouse click on the desktop and hit open a new prompt window here
-write "fastboot boot twrp-3.0.2-19-oneplus3.img" and press enter, your phone should reboot in recovery (keep the prompt open)
-wipe dalvik/system/data/cache/internal storage go back and do format data
-reboot in bootloader(fastboot)
-write in the prompt "fastboot flash recovery twrp-3.0.2-19-oneplus3.img"
-unplug your phone and turn it off switching in fastboot with the volume buttons
-when it's powered off press power+volume down and chose recovery
-now you should boot and flash any rom in recovery (i suggest you to not try to flash any OOS 3.5.6 based roms)
i went back to OOS 3.2.6 but any other custom rom lshould be fine!

My 1+ 3 won´t boot recovery or system

hey guys,
i have a big problem.
i unlocked my one+ 3 2 weeks ago and installed twrp and cm13. all worked fine.
yesterday i read the news from cm the first devices will get offical cm14.
so i donwloaded the first rom and updated my phone (without a wipe!).
the cm14 starts good and all worked fine.
But, i find out, i can´t hear a phone call.
so, i want to go back to the twrp to restore my backup of cm13.
the problems begins....
i can´t boot twrp. i see the bootloader screen and after switching the screen to recovery (normaly) i got a black screen (seems like to shut off the screen).
then i tried to reinstall it, nothing.
after a full evening of trying i wiped it (factory reset) from android 7.
after the reboot i got the same problem. -> black screen after bootscreen Android won´t start, recovery won´t start.
then i downloaded a toolbox and installed the stock recovery -> no change -> black screen.
then i tried to find a stock image als *.img format to flash it with all (kernel and recovery, etc) with fastboot, but i didn´t find an image.
my last try was to make a full wipe with "fastboot -w". but this won´t work too.
so, now my phone will only boot into fastboot and thats it.
i need urgend help.
can anyone tell me what i can do? how can i install any os and wipe via fastboot and with no recovery?
thx a lot for your help.

Lots off people are getting this problem and trust me for some reason people post steps to fix this that are complicated for people who are just getting to playing around with TWRP.
Look, download the original TWRP recovery from here, https://dl.twrp.me/oneplus3/ the one you need is the 3.0.2-1 . I used it and I got back to MC13 From MC14.1 which by the way is now working pretty good. Once you fastboot flash recovery .this 3.0.2-1 recovery you can actually use it with MC14.1 as am doing right now. In any case. flash recovery >factory reset > adb your MC13 Zip to the phone > reboot...

Thanks for your reply.
to flash only the new recovery will not help.
tomorrow i will try to flash, wipe (with "fastboot -w" and copy the zip file.
Will the copy install the cm13 version? or do u mean sideload to have the cm13 zip for the twrp to flash?

Try to flash the modified twrp. Check the official topic for cm 14, it is linked over there

@superiscch just provided you with the TWRP that works. This is what i did !
Flash the recovery provided on the link >boot to the new recovery, you well see the version at the top left corner as 3.0.2-1 > factory reset > adb sideload the MC 13 ....... Reboot system > than add your choice of google apps to the sdcard root > reboot to recovery > flash google apps from with recovery than reboot, you would be golden. After, if your interested just flash the TWRP from the original twrp team. Cuss the one you just installed is modified, it be your choice !!

Hey guys,
thx for your replay. i will try it after work.
but i have one question ... what do u mean exactly with " adb your MC13 Zip"?
do u mean to transfer the zip to install with twrp or is there a command to install the zip to the systempartition?

Okay... Look, once you have flash the modified recovery and you reboot. You be able to boot to your OS. Than you have to simple options 1. Load the CM13 ZIP file to your sdcard which you can use for installing with recovery
2. Boot into recovery and side load the MC 13 ZIP file into your phone using adb...sideload would be using adb
ADB... adb sideload <name of file> without the brackets...
Good luck man

Assistance regarding a possible bricked op3

Hi guys, I searched around the forum before posting this so I apologize but I recently installed a new rom and possibly a wrong kernel with it. Afterwards, if I try to turn it on, it just shows the logo and then turns right off. I can't even go into recovery since it does the same. The only thing I can do is boot it into fastboot but I'm not sure where to go from here. I tried using a guide with no success.
Any words of wisdom?

reflash your recovery via fastboot, then boot into recovery and do a clean install
fastboot flash [recovery].img

I tried reflashing recovery but all it does is show the old rom logo that was used and then shuts down.

Hi,
Read carefully and try this guide:
forum.xda-developers.com/oneplus-3/how-to/guide-mega-unbrick-guide-hard-bricked-t3405700

which rom did you flash? You need the correct twrp file for your bootloader.

That's the first place I tried. Anytime I hook-up my phone to the PC it shows up as OnePlus Android bootloader interface under Android phone and I can't seem to update the drivers..
