Custom recovery issues! Help please!

Guys here's the thing. Android N on my N5X. When trying to install TWRP 3.0.2.2 through Nexus Root Toolkit it first boots up the recovery then when I reboot to system and back there is no TWRP. But it remains there when I use the Root button which roots and installs custom recovery. So when I have root I have TWRP. Can't I have TWRP without root I wonder?

Doesnt the toolkit have a check box to install a script or whatever to patch the system so the recovery wont be over written? Mine has it in flash recovery option!

I'm experiencing this issue as well. I tried to install TWRP after installing that October security updates. I wonder if there's something in the update that is preventing TWRP from installing?

It has something called perm.flash.recovery.zipor something which is described to do the thing you said but the problem is when the phone gets the" flash perm.flash.recovery.zip" it does nothing. It does nothing even when I try to flash it manually when I get the "trial" TWRP which disappears after rebooting.

Had the same problem. I solved it by using the old fashioned way, with fastboot commands found on the TWRP page: https://twrp.me/devices/lgnexus5x.html
Of course, I used the last image: twrp-3.0.2-2-bullhead.img

Cannot install 4.0.2 update

I was using 4.0.0 stock with twrp and root. Tried to install the 4.0.2 update but every boot just took me back to recovery. Tried wiping clean, no change. Tried installing stock recovery v2.0, recovery would hang. Tried using new twrp 3.0.3 and I could get back in, but any ROM, stock or not I installed, would not stick.. Even twrp would warn me "no os installed. reboot anyway?" even when I had just installed a ROM. So in the end I flashed OOS 3.2.8 with twrp and then flashed stock recovery. At this point I'm pretty much at factory stock at v3.2.8 with stock recovery v1.0. Now I'm trying to update to 4.0.2 via OTA and for the 3rd time already I have received a installation failed message and rebooted to system. The first time I thought it was because I disconnected VPN after starting the download, so I downloaded a second and a third time. I don't want to resort to sideloading again because I fear I might get the same no OS installed problem I got when I tried to install 4.0.2 in the first place. Does anyone have any insight on what is wrong?

Steps:
1. Install latest Official or Modified TWRP ( 3.0.3/ 3.0.3 version 14 by eng.stk)
2. Enter into recovery. Connect phone to PC and copy downloaded ROM file.
3. Wipe everything in the recovery- Data, System, cache and Dalvic. It will erase everything.
4. Flash ROM zip after completing, don't reboot phone. Reboot to recovery again, and then reboot phone.
If u reboot phone directly after flashing ROM, u will loose TWRP.

Even twrp would warn me "no os installed. reboot anyway?" even when I had just installed a ROM.

This is pretty normal for nougat OOS. I've faced it for all 3 ROMs i flashed. Don't worry, your ROM was flashed successfully. You can mount and check the /system partition, you can see your ROM files there.
So here's what worked for me. (considering you are on ext4 /data)
1. Flash latest official twrp recovert ext4 version or use the file system swapper zip if it doesn't decrypt your data in recovery. TWRP has some issues as of now and mounts f2fs as default, so you just need to flash the file system swapper zip in order to swap it to ext4 by default.
2. Wipe /system /cache and dalvik cache.
3. Flash full 4.0.2 ROM zip, should be 1.4 GB in size.
4. Flash TWRP image again just in case.
5. Reboot to recovery, not to system.
6. Flash stable 2.79 Super Su and you are good to go.

Thanks for the tip, however I don't mind losing twrp, I only want to get stock unaltered update and this procedure does not help in this

Have you tried this guide: https://forum.xda-developers.com/oneplus-3/how-to/guide-flashing-oos-v4-0-1-custom-rom-t3537757
P.S. I think you did, but I'm just asking.

Thanks for the tip, but I fixed it. Ended up flashing v3.2.8 via twrp and installed OTA to 4.0.1 via sideload. Recovery would not boot unless first fully booted into the system. After that sideloaded 4.0.2 via OTA and now back to complete stock.
Thanks guys!

Unable to recover OxygenOS on Oneplus3

Hello everyone,
This morning, I wanted to recover OxygenOS on my Oneplus3. I'm currently running Cyanogenmod 13.
I used the following guide: "[GUIDE] How to Unroot your OnePlus 3 / 3T and go back completely to stock" (Since I'm a newb, I can't post the link. But Google will get you there)
I booted into fastboot, issued the fastboot flash recovery recovery_op3.img and fastboot oem lock commands from my Linux termina, and rebooted in recovery mode.
In recovery mode, I then erased the cache and all that, selected the "Upgrade android from USB" and issued the adb sideload ota.zip command. This is where my problems began.
After running the command, I got the error "error: protocol fault (no status)". I tried to look this error up, but couldn't find useful information.
I started to panic a bit, fearing that my phone would be bricked. However, after booting back into fastboot mode, unlocking OEM, and rebooting, my phone would boot back into Cyanogenmod 13 (A clean install).
So now I don't have a bricked phone. However, I really would like to go back to OxygenOS, so my question is whether anyone knows how to solve my problem.
Summary:
Running Linux (Debian 8) on my PC;
Running Cyanogenmod13 on my Phone;
Want to recover OxygenOS, but adb sideload gave me "error: protocol fault (no status)";
Tried running the adb sideload command as root, however that did not work;
Can still use the Cyanogenmod13.

I've seen that error once before. I had to disconnect the phone, kill the ADB process, reconnect the phone and restart ADB to get it to work.
That worked for me. Hope that helps.

Hey, thanks for responding.
I forgot to mention that I also tried killing the adb process several times, using the adb kill-server command and by killing the process sending SIGKILL.
Another thing I tried was using another Debian machine, which is my laptop. Still, those things did not solve my issue.

Never relock your boot loader, most bricks are due to relocking.
Flash twrp, flash oxygen os ,boot, enable everything,if you want complete stock, flash stock recovery ,flash oxygen os boot to complete stock os.

Backup youre working rom..
First, you need unlocked bootloader.
1.Flash twrp 3.0.4.1 or twrp-3.1.0 x v.26 blu_spark. Reboot to recovery.
2.Clean flash (wipe data-dalvik-system-cache) Oxygen OS, since you come from a custom rom. Flash SuperSu or Magisk, if you want root. Reflash recovery. Reboot to recovery.
If youre phone does not boot in recovery, press Power till phone vibrates. Press vol. down & choose:
1. Select Bootloader. Flash recovery from PC. Safest way to flash recovery.
or
2.Select recovery. Reflash recovery. Reboot recovery.
After you are sure that you got a working recovery reboot to system.

Since I don't understand everything yet, I will spend this evening looking up everything in detail, before I start giving it another try. Do you perhaps know of a tutorial about this specific situation? I don't want to bother you by questioning everything you stated in your instructions. They seem clear enough to be able to be looked up on Google :laugh:

Thanks for responding.
By the steps after "if you want complete stock", do you mean that I should keep the bootloader unlocked, and then perform the same steps as in the tutorial that I used?
EDIT:
@ null0seven: I found these steps online as I was looking up some things you said (I don't have much time since I will celebrate eastern with my family today)
Rooted Users or users with ROMs other than OxygenOS having new bootloader (Official CM 13,CM 13 Based ROMs dated later than 04 June 2016,H2OS Marshmallow)​
Step 1 :- Download the OxygenOS 3.0.2 full zip from the top of the post.
Step 2 :- Boot into TWRP.Wipe Dalvik,System,Data and Cache.After that,flash OxygenOS 3.0.2.
Step 3 :- [OPTIONAL] Flash SuperSU from here :- https://www.androidfilehost.com/?fid=24459283995297946
Step 4 -> Reboot System.
Of course, this is about an old version of OxygenOS. But it looks the same as you said.
I think this, combined with your instructions, will make it a bit clearer. Still one question: What do you mean exactly by flashing?

Asus Z00A(ZE551ML) bootloops into Recovery!

Hi everyone,
I found similar threads here on the forums, but none of them solved my problem!
My Zenfone 2 (Z00A/ZEE551ML) keeps bootlooping into TWRP, the cause of this issue is when i try to flash the SuperSU v2.8 zip!
My TWRP is 3.1.1, when i flash either Lineage 14 or AOSP/XOSP it boots normally into the OS, but the moment when I install SuperSU the bootloop happens (and yes, I've tried to flash it before and after the first boot of the OS, and it didn't work for either one of these methods)! The problem is that I want to use AOSP and I need Root access, and it doesn't come Rooted out of the box, unlike Lineage. Does anyone have any ideas how to solve this?
Thanks in advance!

Apparently.... my phone refuses to install TWRP 3.0.2......
I'm doing all the steps that I'm used to.... Enable Debugging on dev. options.... adb reboot fastboot.... fastboot flash recovery "TWRP 3.0.2" and it's sucessful....
However... when i try to boot into recovery, the phone goes back to fastboot (although, i can boot it to system normally).
I tried flashing 3.1.1 back again and it worked, it went back to 3.1.1 .... so I'm back at square one.

Check the following topic and download VerifiedBootSigner-v8.zip
https://forum.xda-developers.com/an...signing-boot-images-android-verified-t3600606
Flash SuperSU and don't reboot yet.
Flash VerifiedBootSigner-v8.zip and then reboot.
Let me now if it worked. I had the same problem after installing Magisk. Resigning the bootimage fixed the problem for me.

[SOLVED] HELP! i'm stuck in a boot loop! :(

my flashing history:
i was on audax (oos based nougat rom) with blu spark kernel before, then went to official ob1, then back to audax, then back to stock oos nougat and now i flashed audax and after clean flashing it, it just wont boot up.
when i try to boot up i see the 1+ logo but then it reboots to recovery. i also tried flashing stock nougat again and also flashed stock kernel manually but it also doesnt work.
i always do:
1. wipe system/dalvic/cache/data
2. install ROM
3. wipe dalvik/cache
4. flash magisk (also tried without flashing magisk)
5. reboot
i've been looking on the interwebs all day but nothing worked.. help pls :/
EDIT: problem was blu spark twrp. Maybe installing Oreo ****ed it up. I flashed codeworkx newest twrp universal build and now Im able to boot again!! Btw: I also found that magisk 15.0 prohibits a proper boot up and results in a boot loop. version 15.2, however, does the trick!

when it auto reboot to recovery, formate data

When s**t happens, it is wise to start everything from scratch:
-boot in fastboot mode and flash stock recovery with "fastboot flash recovery recovery.img" (rename recovery.img with your recovery filename), then reboot recovery and select english, advanced, adb sideload;
-flash stock OS with "adb sideload rom.zip" (rename rom.zip with your Oxygen OS filename).
Procedure will require some minute because of the large file size. Remember to save all your data on internal storage first!
I advice you to flash original recovery because often sideloading in TWRP leads to some error.
Your phone will boot again... after that you may reflash TWRP, Magisk etc

I had the same issue. Bootloop and jumb into recovery by itself. You have to flash magisk 15.2 via recovery and will be boot.

He says that it occurs even without Magisk... I had a similar trouble once, and the only way to solve it was the procedure I wrote above...

I dont know if you can boot it w/o root
