Lost recovery after a hard factory reset when using TWRP - Nexus 6P Q&A, Help & Troubleshooting

I recently got a huawei Nexus 6p. I had it with TWRP and rooted. The battery in these as you know the batteries are not the best. I had been told to try a hard factory reset. I then was able to wipe using TWRP and then lost the recovery. I was able to flash a stock version of the android 8.1.0, however, Now when I try to boot in recovery mode I get nothing but an android guy and say's something like no command found. I haven't been able to root it again or flash TWRP. My goal is to root and flash nethunter. Is there any way of fixing the recovery or flashing a new one.

Once you are on the screen with the little green guy laying down, hold the power button and tap volume up. That should take you into recovery.

Boot into Download mode, (voldown + power) then flash normally with fastboot.

Download image to desktop, open command prompt, and type "fastboot flash recovery twrp-3.2.3-0-angler.img" without quotations. You need device drivers and android sdk tools. Bootloader needs to be unlocked as well.

[Q] Stuck in boot loop - Save Photos?

Hi,
my Nexus 4 is stuck in a boot loop since 2 days. I found it turned off and assumed it crashed (has done that once or twice before), but after turning it on it's gets stuck on the boot up screen. I've tried restarting it numerous times, left it on the boot screen for hours - nothing.
I can access the recovery mode and according to most things I've found while searching the internet for a solution a "wipe data/factory reset" would hopefully do the trick, but the thing is... I haven't backed up my device in ages. (Stupid, I know.) I'm travelling and took a lot of pictures that I would hate to loose.
Is there any way to save them? I don't care for app data or anything else.
I wouldn't mind rooting it (was thinking about doing that anyway), but I'm pretty much a n00b when it comes to Android, haven't done more with it than simply using it.
I have read up quite a bit about rooting in the last two days (here on the forum and everywhere else) but I'm still not sure how exactly to do it, since all methods seem to require unlocking the bootloader and therefore deleting my photos (or just don't give much in the way of explanation).
I'm using a mac, but if necessary I also have Windows installed. I have installed Adb and fastboot following this guide.
The phone is not rooted, I don't have developer options or USB debugging enabled and it's running on 4.4.4.
I would be really grateful for help.
If you can boot into the bootloader you can install a custom recovery, I'd recommend twrp. Then booting into the custom recovery you could use adb to pull files off your device . But your bootloader needs to be unlocked. If it isn't I'm afraid you won't be able to get your photos

bootloop issue
A.
Try to go into safe mode and backup your data.
Boot into Safe Mode:
1. Press/Hold Power button until power menu shows up
2. Tap/Hold Power off option
3. Choose OK to reboot in safe mode
B.
For bootloop problem:
Boot into Stock Recovery
1. Power+VolUp while booting to enter recovery
2. You can release buttons after you see Google on screen
(Note: Must be this sequence Press/Hold Power, THEN Press/Release VolUp, release Power)
3. Android fallen down screen - VolUp to toggle recovery menu
Now wipe Cache & Dalvik Cache in recovery and reboot the phone.
C.
If the (Option B) does not solved then try to flash the stock rom with the below given mentioned steps.
First download any stock rom and also the related usb drivers. Install the drivers into the PC.
Boot into the bootloader.
Open (fastboot.exe) Cmd prompt as admin. Put the stock rom into that particular folder.
fastboot flash bootloader filename.img
reboot the phone and return back to the bootloader.
Then, we will flash all other partitions.
fastboot flash radio filename.img
Again reboot the phone and go back into the bootloader
fastboot flash boot filename.
fastboot flash recovery filename.img
fastboot flash userdata filename.img
fastboot flash system filename.img
If you want to relock the bootloader of your device after flashing the device, put the device back in fastboot mode. Then type in the following command in the Terminal or Command Window you had opened earlier -:
fastboot oem lock
This will re-lock the bootloader of your Nexus device, restoring your warranty and putting the device back to complete stock.
I hope this helps you out.
Thank you, but is there a way to boot into safe mode if the phone isn't turned on? I can not get to the power menu since I can't turn the phone on...
I can only access the recovery menu.
Data backup
Alternate method you can do is that you have to download a software by name 'DROID EXPLORER' - (try to google it) you will find this software from the internet. Then install the software on your PC or Laptop. Once you open the software it will take some time to download the sdk files from the internet then install the windows sdk files also.
Later you go into the recovery mode with the usb cable connected to your PC. Then open the Droid Explorer software you will see your phone connected picture. Now double click and open it go to sdcard and copy all your pictures and other files to your system.
Finally, Once you backed up all your files now you can reflash with the proper rom from the recovery mode. From directly inserting the rom.zip file into the sdcard and run the custom rom after you wipe the partitions properly in recovery.
Note: Before wiping the partitions always unmount the system, data, cache and then wipe it.

Problems booting into recovery

Okay, to start with, I've read the other threads about this. I understand the process that *should* work:
1. Power off.
2. Then, press and hold both all Volume Down + Power buttons at the same time until the LG Logo is being displayed on your LG V20.
3. Now, release the keys and press the above combination again however, this time you should wait until recovery mode menu is displayed.
...and I've tried the version where you keep holding the Volume Down button the entire time.
So, yes, I've reached the white screen where it asks you if you want to do a factory reset. I've hit "Yes" to both questions. The problem is that it really does a factory reset then.
---
After unlocking the bootloader, I installed TWRP via fastboot:
adb reboot bootloader
fastboot flash recovery twrp.img
fastboot reboot
...everything went fine.
But I can't get into recovery. And since I'm waiting to have TWRP working so that I can flash root, I can't boot into recovery via an app.
What did I do wrong?
EDIT:
Okay, it looks like TWRP isn't working properly. I tried "adb reboot recovery" and that got me to a dead Android icon and a "No command" message. I have no idea why TWRP isn't working.

to confirm, have you verified you are using the correct TWRP version for your V20?
in this step "fastboot flash recovery twrp.img" is your twrp image that you saved, named twrp.img? If its not, that command won't work correctly.
usually after I flash recovery, when still in the recovery menu, i choose reboot recovery just to make sure it did stick. If it reboots back to itself, then try rebooting the device, and again confirm with manually entering recovery. Maybe overkill but it works for me LOL.
Good luck!
I am in need of big help! I made a critical error after days of trying to navigate the minefields of rooting my device. I have a LG V20 h910 and it is no one-click wonder root. It made me work for it and I finally got it. I loaded LineageOS 14.1 and all was good until the USB OTG cable from my PS4 controller did not register anymore. Damn, that was a let down, and probably led to my careless move of needing to downgrade my TWRP, saw the version I needed, forgot these are device specific, and now I'm stuck in a hard place.
Perhaps the fix is easy, but I have not found the answer after many, many searches...
I had TWRP 3.2.1-2 and needed to downgrade to 3.2.1-0 to try SuperRom (hoping it would have OTG ability). I hastily grabbed the first TWRP 3.2.1-0, threw it on the SD card, wiped everything except internal storage, and flashed the img, and did a reboot. Road block went up.
I tried getting back into recovery, did the PWR and DOWN pressing combo and got the Factory Reset screen, but after clicking "Yes" to both, instead of getting the TWRP screen, I got this error screen (attached).
I tried another idea - hooked it up USB to my PC and tried accessing it via adb/fastboot. I tried multiple drivers for my device, but no adb and no fastboot devices were ever found. The only thing that almost worked was booting phone into FASTBOOT mode by holding DOWN btn and plugging in a USB cable attached to PC. Once in FASTBOOT mode, My PC at least saw the ID for fastboot device. I tried to flash TWRP via fastboot, and it looked like it would happen, but in the end there was no phone screen response to my attempt, and the cmd window on my PC would get stuck and just hang.
Can someone please advise me on how I can fix this problem?

Did fastboot gave some error message, also did you only test to go to recovery straight from fastboot, because that is other recovery which can't be changed.

Just to make sure because the recovery stuff with this device can be at start a bit confusing. Please check does the recovery you boot into have factory reset option in it.
Also can you give a link for the twrp you flashed?

1. Booloader unlocking only affects to what you can flash in fastboot, it doesn't affect stock recovery funtionality.
I asked about factory reset option, because I wanted to make sure you aren't booting to "recovery2/eRecovery". (It doesn't have factory reset option)
2. Avoid using kingoroot and other oneclick root apps if it is possible.
3. Your firmware version doesn't matter.
4. Bootloader unlocking can't cause crash. Locked bootloader could cause crash if system is modified(I think), but you would still be able to get recovery.
One way to make sure you boot to normal recovery is to connect your phone to pc --> open command line --> type "adb reboot recovery". This won't take you to erecovery
I can't do any better help with the current information.
After you successfully flash the recovery with fastboot (always use the latest!) You need to do these things in order (and fast) in order to but to TWRP. If you don't it will boot to stock recovery and you have to fastboot flash again.
You must
a) write fastboot reboot in the console but don't pass Enter!!
b) hold VOLUME UP
c) (still holding VOL UP) presss Enter and remove the USB cable immediately once it says your device is booting now.
Keep holding VOL UP until you boot to TWRP. Allow modifications.
For root you will flash Magisk (you know, normal zip), which a) is open source, so no sneaky stuff and b) can hide root from apps as a bonus. You can always get the zip here: http://tiny.cc/latestmagisk
Important: If you have other root solutions install them for example SuperSU has an uninstall option. Then flash Magisk

The recovery you go from fastboot is eRecovery. You can't boot to stock or TWRP recovery directly from fastboot. If you choose shutdown from eRecovery then you can just go to TWRP with normal way (power + VOL UP). Going to eRecovery doesn't undo TWRP installation. (This also means you can do force update even with TWRP installed, I think, not 100% sure)

I do this every time. See surdu's post here. Fastboot reboo is just a reboot, so the familiar key combo will boot to recovery.

I just wanted to point out that you don't need to re-flash if you happen to only press vol up in fastboot.

Moto e 4 xt1762 woods mediatek stuck on TWRP

Hello, i installed dotos custom rom and gapps after flashed TWRP without root access (i don't want to root my device), all was good, the custom rom work good, so to day i manage to reinstall the same rom with another time gapps (the cause is for delete some application), all was good , and i read that it's good to make a hard reset for that the rom work nicely (i do it from the setting), i do it but after that the smartphone reboot and stuck on TWRP, i reboot the system from TWRP but don't work, it open all the time TWRP, the recovery menu disaper (i use the key volume"-" and power button don't work it don't enter to the recovery mode), i can only boot to bootloader from TWRP and access fastboot mode:
=>fastboot mode
=>unlocked
i use "fastboot continu" to access system but sim don' work in this way. so i come to you for help, i want that the system work like before, thank for your patience and help.
Reboot into fastboot mode
Have at least minimal ADB interface and fastboot drivers installed
Use a command prompt to cd to ur fastboot drivers normally C:\adb
in the same folder have your TWRP recovery image.
Then use the command fastboot flash recovery [twrpfilename.img]
Then fastboot reboot
Hold power and vol down and once in the boot loader use volume up to select recovery then press power to boot into the recovery mode
Have magisk on your SD card or go to reboot and TWRP will root your device you must never try to unroot a custom ROM because at some point they will all fail and you'll be in this problem.. i have hundreds of different custom ROMs from Android 4 to 8 and not one of them has been flawless they all have issues and big problems in the end, like operating system breaking glitches your best off sticking with stock firmware and modded and debloating urselg

Nokia 5 unable to install Recovery

So I gave my IMEI, serial number and $5 to someone on the internet, and in return I got an email attachment to flash to my phone. So I did, and it unlocked the bootloader. Strangely enough, now I'm getting a stupid yellow message that my device is unlocked and can't be trusted, and it's a bit of a roundabout way to get into bootloader or recovery. One ONLY works with buttons, the other ONLY with adb.
Ok, never mind, so I tried installing both the 3.1.1. and 3.2.1 of TWRP custom recovery, but I am unable to boot into it to make it stick. On top of that, my phone now says "encrypted"? WTF?
Clearly this latest incarnation of Nokia is a bunch of asswipes, offering us Sophie's choice instead of just unlocking the damn things from the start, so there's no point in asking them for help, but I'd expect members here would be able to help?
Any ideas how to proceed? Is there a factory ROM somewhere? This is 7.1.2. by the way, I'm not interested in updating. Come to think of it, I hate this so-called "progress" with convoluted "security" and whatnot. Just give me the damn phone and go away, Google+Nokia. Stick your "features" up ya clacker.
1. Okk first you jeed to go this link and download official recovery for nokia 5 running android 8.1 oreo
https://drive.google.com/file/d/1Cl1...w?usp=drivesdk
2. Rename it to twrp and give the command to flash the recovery.
3. After give command fastboot flash recovery twrp.img. Give the command fastboot boot twrp.img
And boooom you enter in official twrp

Err... no, not quite.
1. Your link is (was) dead, but in any case I'd be wary of installing something stashed in a private Google drive folder... Thanks, but no thanks.
2. I have several versions of TWRP, that's not a problem.
3. I know the correct commands (yours are not), that's not a problem.
And boom - no, you don't end up in TWRP. You end up in system, because it overwrites the TWRP automatically UNLESS you reboot to it immediately after flashing, and THIS is the problem.
It turns out that Nokia needs to be plugged into CHARGER, not the PC, then holding Vol+ and Power button combination will do it. It took me more than a dozen tries, but it worked in the end.
Hi, I had the same problem. I've unlocked bootloader and I successfully installed TWRP and I can go to recovery but the problem is I can't boot the system as it stucks on download mode. Can you help?
Press volume up+volume down+power button at the same time for 7-8 second.
