Flashed TWRP, now I have no OS - Nexus 7 (2013) Q&A

Ok, unlocked my bootloader via the command fastboot OEM unlock, then I flashed TWRP 2.6.0.0. I pressed Start on the bootloader, the my Nexus went into recovery mode, so I tapped reboot, and TWRP said No OS Installed!. Now I know this is a soft-brick (how can it be brick since there is no OS?) since I can restart my device. I would have just went and reinstalled a factory image right, but I am here asking if I can just install Cyganmod 10.2 instead, even though Android is gone?

It will boot but it now hangs at the boot animation

Please, describe, what exactly you want to do?
Stock rooted ROM with TWRP?
CM or any other ROM?
Or a what?

You can. Why an old as **** twrp and rom though?

If this is a newer build, man date 12/14 or later you need to use multirom TWRP. See here, http://forum.xda-developers.com/nexus-7-2013/nexus-7-2013-qa/mount-recovery-t3064562

Help Please. Soft-Bricked Device

Hello all!
I recently flashed the 4.16.xx firmware to my device. I am now stuck on the Bliss Rom bootscreen for some reason. Booting into recovery takes me to stock recovery and the phone isn't being recognized through ADB on several different PC's.
Am I screwed here? Any options?
Thanks for any input.
Try going into the fastboot option from the hboot (or called bootloader to many people. To get to hboot, do power and volume down when the phone is booting up. ) and try flashing your TWRP recovery from there. Also make sure your drivers are working.
If you don't know how to flash recovery just Google it, you should be fine.
Dw, dont panic, it'll be fine xD

Stock recovery is the logical result for flashing firmware, unless the firmware was hacked to remove stock recovery.
adb not working, is also normal. You need to be in OS or recovery to use adb commands (and I don't know whether you can with stock recovery). adb does not work in bootloader.
If you flashed an official firmware with s-on, then not boot is also the expected result.
You need to unlock the bootloader again, flash TWRP back onto the phone, and flash a ROM.

Hey thanks for the reply!
I figured it out finally and forgot to update the post. I ended up finding and flashing a Lollipop RUU from the SDcard and that got me booted up. Then I just had to re-flash TWRP, re-root and flash a new rom.
All is well now. Thanks for trying to help out.

[HELP GUIDE] - Can't flash TWRP on Oxygen OS 3.2.1

Today I have faced a strange situation, I installed TWRP (after unlocking the bootloader) on my OP3 as soon as I received the device then I flashed custom ROM by @Grarak http://forum.xda-developers.com/oneplus-3/development/rom-unofficial-cyanogenmod-13-t3399089.
After using for some days I decided to give Oxygen OS another try, so I wiped the cache,data,system and Flashed full OTA provided by @namanbhalla https://forums.oneplus.net/threads/...ficial-oxygen-os-roms-and-ota-updates.450783/
Every thing went smooth but after starting up I wasn't able to goto twrp, for some strange reason twrp was automatically replaced with stock recovery. OK, I decided to reflash twrp, but bang! after so many flashing I wasn't able to boot into twrp, still there was stock recovery.
Solution:
1) fastboot oem unlock (re run even if it says already unlocked)
2) fastboot flash recovery twrp-3.0.2-0-oneplus3.img
now TWRP is installed.
I not Android Developer and cant guarantee above will work and wont harm your device. Try at your own risk.
that is all not needed, i have had this happen to me multiple times reflashing Stock and Stock recovery replaces TWRP, all u have to do is boot up to fastboot mode and flash TWRP, do not reboot, use Power + Vol + and when the Unlocked bootloader screen comes up press the VOL key and click recovery and TWRP is back. no need to do the unlock bootloader again, unless u unchecked it, just make sure it is checked when flashing the Stock rom again or u can just use flashify if u rooted stock before the recovery got replaced somehow, i have even had this happen on FreedomOS 3.2.1

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:

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?

[HELP] Mate SE in TWRP bootloop after installing openkirin lineageOS beta 4

Mate SE, installed TWRP 3.2.1-0 Pretorian80 Edition then installed openKirin lineageOS beta 4. Went to do a factory reset and now TWRP starts on startup but does not get past the loading page. Tried rebooting into bootloader, using the button combo or adb reboot bootloader only brings TWRP back up with the same issue. Any ideas?
From what I understand, you need to flash lineage via fastboot. Did you do that??

Yeah I launched the bootloader and used fastboot to flash it. The flash went through fine, then it rebooted and asked if I wanted to factory reset the device and I selected yes. Now it won't shut off, it only reboots into TWRP's loading page and sits there.
I should mention I have access to some ADB commands now but rebooting into bootloader won't work.
EDIT: got it working, just had to time rebooting it and plugging it in and holding vol- and power correctly, took me 30 or so tries, fml

Directly from OpenKirin's install guide:
"TWRP and other custom recoveries are not supported! Please ensure you have your device’s stock recovery installed. If you install the ROM with a custom recovery, we cannot assist you with any issues which may arise."

Yeah....I skipped over the sentence saying "please ensure you have your device's stock recovery installed" and thought installing it via fastboot without using TWRP it would be fine. It was not. IMO they should make the warning more dire.
All fixed and working now, thanks for your input.
How did you get it fixed?

Bootloader re-locked

After updating the MIUI, I found to my dismay that TWRP was gone.
But the phone status still says "unlocked".
I re-flashed TWRP but did not boot into it directly.
When I wanted to enter TWRP later (after having booted notmally once), TWRP was still gone. Just the stock bootloader.
Could it be that I have to flash and then boot into TWRP directly in order to make it persistent?
Yes. After flashing twrp boot to recovery or else the recovery restores to stock recovery.
Ok. Will do it this weekend.

Ok. That solved it.
