[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
So I wanted to install a CM ver on my mother's Redmi 1s and first thing I have to do is root the device right?
<image>
I have tried downloading several SuperSU.zip from multiple sources, including here at xda forums and the miui forums, to no avail.
Every single attempt has been a failure using the Stock Recovery that comes with the phone.
Fine then, I'll just use a custom recovery. I then connected the phone to my laptop via USB and used the sdk I downloaded.
After typing this line >>adb reboot bootloader, the phone booted into a screen with the fastboot bunny, all normal yes?
Then I typed >>fastboot oem unlock, but the image below doesn't show up on the phone
<image>
Instead, the command prompt just shows a few lines of the process completing
<image>
I continued to enter>>fastboot flash recovery customrecovery.img into cmd with the custom recovery image IN the platform-tools folder in sdk. Cmd again shows a few lines saying that the process completed.
<image>
However the phone still stays on the screen with the fastboot bunny, even after rebooting and then entering recovery mode, it is still the stock one. I have searched everywhere on how to root this phone but they just showed to install the SuperSU.zip using the stock recovery or the sdk method. If anyone could just help me solve this issue that would be great. If you need more information that I can provide regarding the issue feel free to ask. Thanks in advance !
P.s. Due to xda preventing me from posting outside links since I have not met the threshold, anyone who needs the pictures can message me privately.
Edit: Ah yes, I should also mention that I have tried using the stock Updater app to install the SuperSU.zip as well but that doesn't work. Also, I have tried using King Root and Kingo Root as the easy way, same thing.
Find the TWRP image for our device. I don't prefer the fastboot method; flashing TWRP and then the SuperSU zip is a whole lot more convenient as you don't need a computer.

But doesn't flashing TWRP without PC (with an app) requires the phone to be rooted to begin with? Or is there any workaround method?
Then use Philz recovery. There's a sticky in the general section that provides a link to such a guide using Philz. After rooting you can flash TWRP.

Nope, still doesn't work. Tried using the stock recovery to install update.zip and also flashing the .img via sdk, both doesn't work. I'm again out of options.
before do this backup your device
you can install custom recovery with official fastboot rom.
download any official fastboot rom for your device (stable or beta does not matter)
download twrp .img file for your device
rename your recovery image file to "recovery.img"
extract the fastboot rom
go to "images" folder in extracted fastboot rom
overwrite recovery.img file with your downloaded file
flash the fastboot rom with mi flash.
wait for the installation to complete
setup your device
turn off your device and go to custom twrp recovery.
after that you can install supersu or any custom rom via twrp.
I hope you have checked this post

For me..I started with a zip file containing the custom recovery (TWRP) it was named as Update.zip I got it from a tutorial I googled (noob, I know)...and I flashed it using stock recovery (Redmi 1s don't have locked bootloaders, I guess) and then I had Custom recovery installed..I made a backup of MIUI (it was unrooted, stock) and then flashed the CM 12.1( it was the latest then). Then there was no looking back.
I absolutely hate the navigation buttons and the lack of a app drawer so I jumped when I heard I could put a custom Rom on it. So I unlocked the boot loader but couldn't for the life of me get twrp on it so feeling defeated I decided not to mess with it but now the darn thing won't boot it goes to the recovery screen and not any further. So I guess I need help reversing this or completing the twrp install... I don't really care which cuz I just need a working phone. (Preferably with twrp installed so I can put a different Rom on..)
Need a working phone with stock? Extremely easy. Flashing stock has been made very easy.
Just download factory image and follow the instructions here
https://insider.razerzone.com/index.php?threads/robin-factory-images-and-usb-driver.21487/
And since you cannot boot just reach the recovery page, check if you are able to run fastboot command (fastboot devices) and then run the bat file as instructed in the guide above.
This will wipe everything and help you flash stock to your device.
Getting recovery on Robin is easy too. Not sure what went wrong for you. Make sure you have everything in place first.
Download and install Minimal adb/fastboot https://insider.razerzone.com/index...der-flash-custom-recovery-decrypt-root.23775/
Download and install Robin USB Drivers (just in case) https://insider.razerzone.com/index.php?threads/robin-factory-images-and-usb-driver.21487/
Download latest TWRP https://dl.twrp.me/ether/
Download latest factory image https://insider.razerzone.com/index.php?threads/robin-factory-images-and-usb-driver.21487/
If you want to root then get the latest version of Magisk https://forum.xda-developers.com/apps/magisk (v14 worked fine for me)
Download the custom ROM of your choice
After unlocking the bootloader, just flash the recovery file with the fastboot command and select recovery on your device, you should see TWRP in 1-2 minutes.
Watch this video till 7:34 https://www.youtube.com/watch?v=DKyEhn9clNw
Once you have flashed TWRP properly, now you can push magsik, ROM and gapps and flash them one by one to root and install custom ROM of your choice.
Hope it helps.
I've unlocked my Bootloader and all via beta-test program from DCUnlocker. I wanted to install TWRP & Magisk and I have following every step available from sir Supersonic's guide, but whenever I opened recovery, it always shows stock recovery (eRecovery) even though my CMD states that the flash recovery was succesfull and I never let my phone boot up in order not to replace the TWRP just like any android devices normal recovery procedures.

can someone find a solution of this problem?
I have an ATT LG V40 on android 8.1. The phone is already rooted and has magisk installed. I have been unable to get TWRP installed so I can flash a custom rom. It seems that being on android 8.1 is causing issues, but I am not really sure. I followed this guide: https://forum.xda-developers.com/t/twrp-lg-v40-judypn.3970111/ and when I send the comand to flash TWRP in the command window is says the flash is finished and my phone boots up, but it doesn't seem to do anything. Any help would be greatly appreciated, thanks.
You need to use LGUP to get to 9
Noob question but did you installed and tried magisk manager(I bet you already have) and flashify(searchable on Google) (magisk manager grants root to flashify and flashify installs twrp from storage)?
Are you certain that you're booting in to recovery? Many phones have an advanced reboot menu option on the developer settings. If yours doesn't I recommend an app like Simple Reboot.
If you're not certain that it's installing the recovery correctly have you just tried installing TWRP.zip from Magisk?

Which 'command', specifically, are you typing in when you say you are 'when I send the command to flash twrp'? The only command in those directions are to boot twrp, not flash it.
After you boot it, then you need the advanced section so you can recovery ramdisk, which will inject twrp into the current boot partition (and it keeps boot intact).
If you want to use current aosp roms, then follow the 'metadata' sections as you'll need that version of twrp for those roms.
cheers
