Hi guys, I was following the post in the development forum to boot twrp to install the chains superuser zip, but when I do "fastboot boot <recovery filename>" I Just get "waiting for device". I know the USB connection and SDK is working properly because I unlocked the bootloader. I would just flash twrp straight out but the OP said he preferred to wait until factory images were out to do something like that and it sounded like a good idea to me as well. Any idea what I'm doing wrong? Never had this problem with my GNex but then I never tried to just boot a recovery with it instead of flashing either.
Wow sorry apparently I totally noobed that up. I was actually typing "fastboot boot recovery <recovery filename>" while in the bootloader and that's why it wouldn't work. Currently performing a backup via a booted but not flashed TWRP right now.

[Please help]Bootloop, adb "unauthorized, fastboot flash not working, CWN not working
Hi everybody!
First of all, I'm not an Android noob, I've experience with fastboot and adb commands, android app developement and Stock/Custom Roms/recoveries in general.
Also, I extensively used google and the xda search for this issue but unfortunately didn't come any further.
To make things a little shorter, and avoid a wall of text, here are my problems.
- I'm using CM11 and CWM on a rooted Maguro.
- Initial Problem: Device is stuck in a Bootloop and I want to backup my personal data
- Therfore, wiping is not desired.
- I can boot into Downloading Mode (e.g. for Odin) and Bootloader Mode
- I can boot into recovery (CWM 6.0.4.7) through bootloader menu or fastboot
- In recovery, adb recognizes the device but it is displayed as "unauthorized", so I cant pull any files that way
- Afaik, the device should be accessible in recovery mode, so I thought maybe it would be a good idea, if I installed TWRP instead of CWM and see if it works then.
- I tried installing the new recovery (TWRP) through fastboot (fastboot erase recovery, fastboot flash recovery), and fastboot states, that it was successfull. HOWEVER, when I reboot, the recovery is still CWM and untouched.
- I read, that CM11 may under certain circumstances overwrite any recovery with CWM ob boot, so I made sure to direktly boot into recovery from the bootloader after flashing TWRP over fastboot. Still, CWM is untouched.
- I tried installing TWRP over Odin. Odin too states, that flashing the recovery was successful, but again, CWM remains untouched.
- Then I tried erasing and reflashing "bootloader", "radio", "boot" and a stock "system" through fastboot. (I carefully did not erase "userdata"). All finished successfully according to fastboot but a reboot showed the system in the same state as before.
- At this point, I assume, that I don't have write-access to the device anymore, as silly as that sounds.
At this point, I'm stuck at a dead end and don't know how to proceed, so every help you could provide would be incredibly appreciated.
Of course, I'm also willing to go into more details, but in order to keep this post from getting too long, I didn't do it in the first place.
Many thanks in advance for oyu assistance!

Sorry, but I can't see, how this is supposed to help, since my problem is not "I'm looking for a new ROM"
sorry for the misunderstanding

Your personal data includes what?? Apps or photos and videos?

have you tried using the fastboot boot "/path/to/recovery.img-name-here" fastboot option to just directly boot into twrp without installing it? I used to use fastboot boot for different recovery and boot imgs I wanted to test out first before actually installing them. and I had a similar issue to what yours sounds like before in which I was able to use fastboot boot recovery.img when I wasn't able to get different custom recovery to install at the time.

I used this method
*I boot into costum temporary recovery "TWRP 2.8.3.0" Then I tried erasing and reflashing "bootloader", "radio", "boot" and new "system" through recovery All finished successfully according to TWRP but a reboot showed the system in the same state as before
Hello Everyone I am hoping there is a solution to this however I have been unable to find anything.
I flashed the latest OTA image via sideload and everything was fine until I tried to install TWRP. When trying to install the latest TWRP I could find ( 3.1.0-0RC2 ) my phone would then boot loop. I tried this process several times and each time after installing my phone would boot loop for 10 minutes until I forced it into fastboot, fast booted the TWRP image, and finally sideload the OTA once again.
I have seen a couple threads which I believe indicate that May update changed/broke something with the bootloader but I will be honest I
haven't read into it much.
This is on a Google version of the device with the bootloader unlocked. (failed to mention that).
Thanks in advance.

Please read the other Posts about this
Flash the bootloader from april.
****************************
Download last months 7.1.2 factory image.
Extract it and find "bootloader-marlin-xxxxblahblah.img".
Rename it to "bootloader.img" for simplicity's sake, then move it to the side.
:Flash-all" the latest factory image, after its done stay in fastboot.
Run "fastboot flash bootloader_a bootloader.img" from wherever you moved the file to
Disregard if "partition_a" isnt your primary, once the command is ran it will auto flash to the primary partition.
Boot and setup, reboot back to bootloader.
Boot and install twrp, then reboot to recovery.
Delete fstab.marlin in main directory, then flash preferred supersu (i use 2.79 sr3).
Reboot to system and your done. from here reboot to recovery or bootloader to flash your preferred kernel and mods.
Was able to get this all sorted out.
If anyone else happens to see this thread with the same issues and missed the April bootloader deal you can find a good overview Here
To get the April bootloader image which is something I have never loaded myself you need to download the Factory Image from April then extract it. Inside there you will see the bootloader image.
Hope this helps anyone else who didn't read far enough into this issue.
Hey guys and gals,
Silly question.
For a few months now, I've had TWRP 3.1.0 RC2 installed and no matter what I do, I absolutely cannot reboot into recovery. If I choose reboot to recovery while the phone is running, it results in a ramdump and eventually boots to system. If I reboot into the bootloader and choose to boot into recovery mode from there, it just boots to system. It's incredibly annoying. Literally the only time I can get into recovery is when I connect my phone to a computer and fastboot boot into a temporary TWRP Img and install TWRP again. Once I boot into system, I can never boot into recovery again. This is extremely inconvenient on the go, like right now, because I want to flash V4A before I start playing music from my Bluetooth speaker. Guess I'll just listen to low quality music :'(
What am I doing wrong? This is stupid.

I had the same problem, then I got a twrp boot loop, ended up having to boot into slot b and reflash stock img through adb, beware...
I was JUST about to post this! Exact same problem to the tee (except using RC1)! Hopefully someone smarter can chime in lol

Anyone got some insight to this? Can't be that uncommon of a problem...
Try starting the process again.
Boot to bootloader
Fastboot boot 3.0.2 rc1
In twrp flash 3.1.0 r 2
Reboot recovery and check if it works

I never had TWRP stick unless I added another step to your instructions --boot completely into the rom once, go back into the bootloader, open temp TWRP and flash the TWRP zip again. If I didn't do this my recovery would always revert to stock but, strangely, even though I was running a custom rom the combination of the custom rom and stock recovery never bootlooped my phone and I was able to boot from the stock recovery to the custom rom with no problems. The only reason not being able to boot into TWRP was even an issue was that you can't flash any zips in recovery without it. Otherwise the phone ran so perfectly I didn't even realize at first that TWRP wasn't still the installed recovery.
Get the stock boot.img (this will remove root/kernel/twrp)
Boot into the bootloader
Fastboot flash boot boot.img
Fastboot --set-active=a or b (switch to the inactive slot)
Fastboot reboot bootloader
Fastboot flash boot boot.img
Fastboot --set-active=a or b (reload previous slot)
Fastboot reboot bootloader
Fastboot BOOT twrp.img
Flash TWRP in twrp..
If you can do that I would be interested in your results.
Also pointing out flashing rooms and certain zips here in the forums WILL revert you back to a stock recovery. Just my last bit of helpful information, hope someone gets it figured out, flashing is already a chore for those of us who like to experiment.

I was able to boot into recovery after doing this. Got a bootloop booting into system though, but flashing the ROM (and TWRP) fixed it.
Hello,
Try booting to TWRP 3.0.2 RC1 then flash TWRP 3.0.2 RC1 + SR1-SU v2.82SR1 + SU Pixel Fix (from Chains beta thread) one right after the other in the same TWRP session then reboot. Should fix your issue, give you recovery+root without ram dump.
Cheers
Everytime you flash a rom you need to flash twrp before rebooting or you'll lose twrp recovery.
Unfortunately I've had to get my Pixel XL replaced due to a defect and received a Verizon edition XL running 7.1.1. This is what I get for buying it from Best Buy Therefore I cannot unlock the bootloader and this problem no longer applies to me.
I'll keep this thread open for a bit in case it's useful for anyone else. I'll just sit here in all of my Stock-ness.
I couldn't get this to work. Tried flashing stock boot.img, then booting off of the TWRP images but I keep getting TWRP boot loop. Any suggestions? Tried flashing the entire stock image as well and no dice...
I had TWRP 2.8.7.0 and wanted to flash a ROM that required 3.0.2.0. I found the directions here in XDA to flash TWRP with TWRP. https://www.xda-developers.com/how-to-install-twrp/ I installed the TWRP 3.0.20. image to recovery and almost instantly it said Flashed successfully. Here is where I messed up... I missed step 5 "fastboot reboot", and I pulled the battery.
Now when I go to recovery, I get the factory reset screens and click yes, yes and then black screen with tiny tiny [4 numbers to small to read] Fastboot mode started!
I've tried fashing in ADB, device is recognized, but after "reboot bootloader" command the phone reboots into bootloader mode, then I get "waiting for device" after "flashboot flash recovery twrp.img"
It seems now that when the phone is in bootloader mode, ADB does not recognize it anymore...
Somehow, I also lost root and although my phone still boots up okay, I haven't been able to get it rooted again and so I can;t flash TWRP with the official app.
I running the Tesla ROM 7.1.2 RC
First of all i am sorry to post the same question when it is already in the forum, i did alot of digging and i couldn't find answer in thread. So here is what happened
i am using Ubuntu
i have ADB and Fastboot installed, i have been using them for long time now without any problem, i decided to update my OP3, And OP3T 2 days back. it wasn't working at first but i finally managed to install update, now i am stuck with this error " Can't load twrp.img" i am trying to flash twrp on both devices but i am getting same error
Bootloader unlocked or not?
Check it.
Fastboot command
fastboot OEM device-info
If unlocked, twrp.img should be in fastboot folder.
What recovery ?
Must be the latest!
I recomand blu spark twrp v.8.54 by eng stk. Flash with ADB in Bootloader/Fastboot mode.
Yup bootloader unlocked, i have been using magisk on previous version which was 4.5.1
but after update to 5.0 nothing seems to work, i managed to flash 5.0
when i install twrp it works fine but after first boot it reverts back to stock recovery.
Thanks for your comment, i tried blu spark too but it did not work either.
There's a modified twrp for stock oreo. Blu spark's recovery won't work.(didn't work for me personally)
I tried recovery from this thread and it worked like charm.
Btw It is Solved now. Thanks for your time and Info.
What did you do?
