[EDITED] TWRP install query [G920F] (Was: 'weird behaviour after factory reset?') - Galaxy S6 Q&A, Help & Troubleshooting

Hi All,
I'm hoping you can help me out.
I'm starting to think that there's probably no fault, and that my first attempt to install TWRP was unsuccessful because I didn't know that I should disable 'Auto Reboot' in Odin and boot to [TWRP] recovery before allowing Android to boot again.
I'd be very grateful if someone could clarify, before I try again, that 'enable system modifications' will be required to flash custom roms from TWRP? If that's the case, do I need to root and/or flash 'no-verity-opt-encrypt.zip' as mentioned elsewhere? (The guide I found which mentions the latter is quite old, and the link is dead. I'm hoping TWRP no longer requires this step(?))
Thanks & regards,
Rob.

Stuck at Logo

Hello guys,
I have a problem, I hope you can help me with.
I used to have an EOS ROM. I decided to do factory reset and thats when my problems started. It didn't boot up anymore. After entering recovery I noticed it couldn't mount System partition. I tried reinstalling the ROM, but no success. Everytime I entered recovery, the System checkbox wasnt marked. So I decided to go back to stock, using http://androidforums.com/threads/return-your-xoom-to-stock.653230/. Now it is stuck at Logo screen and can't enter Recovery. (Goes to Reading ODM fuse, but not any further). I can still enter Fastboot and my laptop detects the tablet, when hooked up to it.
Please help me push the Recovery, cuz I'm getting "device not found" from ADB. I'm kinda lost here... Any help would be appreciated!
Update
I managed to install TWRP, but still can't mount System Partition. On wipe I get "Failed"when trying to clean the system part. I have tried Clockwork, it didn't help either.
Cmon guys! I don't want to JTAG it yet.

I am not very knowledgable about flashing, but one suggestion has come to my mind: if you can now get into TWRP (it wasn't clear whether you could based on your last post), try flashing a ROM without trying to clean the system partition. Just make sure the ROM matches the TWRP (i.e., big part ROM with big part TWRP).
Oh - another thought - folks in a number of threads have stated you need to explicitly follow both the recovery and ROM instructions for the XOOM. If you miss a step, people have had issues.

TWRP screen flickering - unable to fastboot

Hi all, I am a novice and would appreciate some help.
In the processes of flashing a rom I erased the whole tablet using the Wipe option in TWRP. I then flashed a rom using adb sideload successfully however there were some errors message regarding unable to access certain folders. From memory /data was one of them and there were others. I then reboot to recovery again, tablet restarted, showed TWRP and screen looped on and off showing TWRP logo, like it was trying to load TWRP. Seems like i need to create these folders again. I have pulled the recovery log via adb however I do not know how to upload it to the post.
You are going to hacve to give us a lot more than thsis to be able to help...
Booloader and recoevry versions, which rom you tried to flash to start with.
How did you flash TWRP?
Why no fastboot? What's happening if you try to boot into fastboot?
You may want to head to the general section and read the frist sticky: The Beginners Guide. Lots of stuff in there that may help you

Stuck on Boot screen after flashing TWRP

Hello,
I just flashed the latest ROM for the S8+ (AQL5) and that went well.
Afterwards I tried to flash TWRP, but now the phone is stuck on the Samsung screen.
I then followed the guide I found here to use the BL file of AQF7 in Odin and spam the Start button so I managed to get into TWRP.
Question is, what do I do next? I restart the system it's the same problem all over again.
No one explains anywhere what to do in TWRP to save the phone.
Can I remove TWRP or somehow save the phone (without wiping my data)
Please help
Can you get to download mode? Then go to ODIN and redo your flashing of the OS and then TWRP. After the flash of TWRP, immediately boot into TWRP, and do Verity if you want that, and your root, if not already done. Clear Dalvik/cache and reboot to system.
It is not uncommon for folks, following TWRP flash, to get stuck in boot loop, unfortunately. Can take a little time, but you will get through it and finally to System.
But I thought all new firmware versions are incompatible with TWRP and cause this error.
I might try to install TWRP again if I flash the latest compatible version (I think it's the F7 one).
Does "Verify" in TWRP make that annoying "Your phone is not verified" message go away? The only option is to Reset phone when that thing comes up and I don't want to do that.
I managed to get out of that by reflashing the AQL5 version and just not installing TWPR.
Kind of scared to retry because everything goes wrong when I try to follow the guides on here or youtube

Can't reboot to Recovery after upgrade to Android 10

Hello everyone,
As I mentioned in the title, since I upgraded to Android 10, can't boot to recovery.
Dowloaded latest version of the Adb kit, and while issuing
adb reboot recovery
the phone reboots but goes to normal boot.
Tried manually (power + vol down etc.) and when choosing Recovery - same thing happens.
Needless to say that my laptop is authorized debug device and phone is in debug mode etc. - I have done this many times before Android 10 update.
All I try to do is to sideload the latest OTA as I did many times before because my phone is rooted and the updates do not install automatically.
Pixel (First generation)
Rooted with Magisk
Bootloader unlocked
Stock recovery (using TWRP without installing it when flashing Magisk)
Hope somebody can advise. Obviously there is something new in Android 10 which has to be set (like the need for debugging authorization for example, which I already did).
Thank you
John
Im getting a similar problem. I get stuck on th Google logo screen. I cant hard-reset, recovery mode or boot, the only things that works is th barcode.
Android 10 changed something in the ramdisk that you can't install TWRP directly on the phone. You have to boot it via PC using "fastboot boot <insert twrp image name>.img"
You can try installing twrp to ramdisk. Put twrp 3.3.1-0.img in your devices storage and then fastboot twrp 3.3.0-0 (disable pin etc first) then once it's booted go to advanced and select install to ramdisk and select the 3.3.1-0.img and it should install it. You may get a not enough storage error on 10/Q (I did) bit worth a punt. Make a back up first as usual, if no good flash a fresh factory.img and see if that cures it and then restore your apps/data etcfrom your Google back up (if you use it)
Good luck

Thank you for the advice, however as I mentioned in my original post I don't want to install TWRP permanently , and the problem is that I cannot go to the stock recovery mode which has no connection to TWRP. There is something with Android 10 which changed since 9 and I'm interested to find what. Everything worked fine before the upgrade.
Also, the option to flash factory image and restore (I also have Titanium in addition to Google backup) is a too much of a hassle. I use this phone for real, not only to play with it.
Anyway, again thank you for your input.
John
Sorry mate, re read your OP. I just tried booting into the aosp recovery and got the same issue! My guess is its magisk as I could boot into the aosp recovery prior to installing it. Re flash or restore the previous boot.img or a stock boot.img and it should boot into aosp recovery again. Magisk must be installing to or patching the aosp recovery ramdisk and stopping it booting. Other than that just fastboot twrp and use that.
Edit: it's magisk, restored original images and it booted into aosp recovery first try.
I've had no problems installing TWRP 3.3.0.0 normally after using an *.img file to get TWRP started. EDIT: and booting into it.

You are right. I did open Magisk and from the uninstall options choosed "Restore images" (no need to do complete uninstall, which is the other option). After that I was able to boot in recovery etc. I guess this is what you meant in your PS. At the end re-flashed Magisk and all is back to normal.
I will alert the Magisk team about the issue (if they are not already aware).
Case closed.
Thanks again.

Please read my OP. I was clear that I DON'T want to install TWRP permanently and this was never the problem.
The problem is solved (kind of). See the other posts.
Thank you.

Are there steps for how to install somewhere? I keep reading that it's not working on the Pixel with Android 10. Thanks

It is a mess. It works with Pixel (I have this one and can confirm) and supposedly Pixel 2. It won't work for brand new phones arriving with factory installed Android 10.
Read the following:
https://twrp.me/site/update/2019/10/23/twrp-and-android-10.html#
After that, if you want to try, go to the page below to find instructions for your device. Note that the list is by manufacturer, so if you are looking for Pixel, it is under Google.
https://twrp.me/Devices/
Just in case - backup and have the factory image for your phone handy in case something goes wrong. For google phones you can download the image and see instructions here:
https://developers.google.com/android/images
Note that I never installed TWRP permanently, so I can't say if the permanent installation will work (I think it should, but not sure). Typically I just load TWRP and use it to flash pakages, but at the end I'm keeping the stock recovery.
Hope this helps. Good luck.

Thanks. Yea from what I can tell no one has had luck actually installing it on the Pixel with Android 10 yet. I'm familiar with how to fix everything if something goes wrong. I would try but others have already tried and failed. It won't install for them.
firstly, dont use whatever ****ty platform-tools you are using, get them from here.
secondly, you dont install recovery on android 10 yet, it doenst work. you have to just boot to twrp using `fastboot boot twrp.img` once you are in bootloader mode.

Rooting ASUS ROG phone 1

I have been trying to root my ASUS ROG Phone 1 for almost a month now. I already opened the bootloader, however, I am struggling in finding the right TWRP image. I tried too many images some of which locked the phone (the phone starts to ask for a password after rebooting and I had to reset factory). Other images do nothing, i.e., when I run fastboot boot twrp_Z01QD..img, the CMD shows that the boot was successful, but the phone does not reboot into TWRP. Lately, I used an image that indeed reboots the phone into the TWRP recovery, however, TWRP asks for a decryption password. I use no password for my phone. I tried the "default_password" password. None of them worked. After that, I removed the data encryption totally from my phone by running the following commands: fastboot format userdata; fastboot format cache; fastboot reboot. However, this did not solve the problem.
I think that the problem might be in the version of TWRP I am using. Any help in locating the right image to be used will be highly appreciated. Also, if you have any clue how to go around the password, please let me know.
If there is anything not clear in my request, please let me know.
Thank you in advance.
You should try porting twrp recovery
Just search on google how to port twrp recovery.
Hey Dreto, thank you for your help. I googled how to port TWRP recovery, and I felt that it is a time-consuming process so I decided to keep it as my last resort. So before trying it, I tried to flash the image without the help of TWRP and it worked out. The phone is now rooted.
Again, thank you for your help.
