Hi everyone,
I tried to update my rooted Pixel C with Android 8 and TWRP 3.1.0.0 from August build to September build with FlashFire.
All of the following have I done on my Nexus 5x as well and it worked as a charm there.
Therefore i dl'd the corresponding zip-file from google dev page and started the update with FF. It said to me it can update the boot, system, recovery and vendor partition so I unchecked the recovery partition only to keep TWRP. I also told FF it should include SuperSU again to root the new Android.
After the update the device was unrooted, so i tried to start into recovery to install superSU manually. But TWRP was gone and i get everytime the android on the back with the text "no command".
Therefore I tried to flash TWRP with NRT again. But after the flash the device always starts into TWRP and Android isn't starting anymore.
I can use NRT again to flash Android without loosing my data but than TWRP is gone again.
So either the device always starts into TWRP or I have no recovery installed.
Anyone an idea what i can do to flash TWRP again and to fix the boot order or whats broken than?
Regards,
flattervieh
I don't have the C but here's what I would try. First, have your device booting normally with the stock recovery. Then use fastboot to boot into TWRP, not flash it. When it boots into TWRP then flash supersu. From TWRP then boot back into the bootloader and then flash TWRP with fastboot.
Flash the latest (beta?) TWRP. It allows reading the encrypted data folder.
Short notice, i'm still struggling with the problem.
In the meantime I tried the following:
1. I temporarely booted TWRP 3.1.0.0, with this version I was not able to encrypt the data partion (always invalid key) but I was able to see the system partition and I installed SuperSU. After that i restarted into the bootloader and flashed TWRP 3.1.0.0.
This led to the same phenomenon, that my pixel always boots into TWRP and not into Android itself.
2. Same thing as before but with TWRP 3.1.1.1.
With this version I was able to see the size of the data partition, but I was also not able to read or write onto it. (Again invalid code) I installed SuperSU and made a device restart without flashing TWRP 3.1.1.1.
This led to a totally softbricked device with a boot into "no command" screen.
After flashing Android again via fastboot Android starts correctly and I can use the device but root is still not working.
Regards
I'm not sure why twrp isn't sticking. But the android on its back with "no command"is the stock recovery. To get into it simultaneously press and release the power and vol up keys. You might have to try it a few times as the timing can be very finicky. From there you can boot into the system, you don't need to flash the factory image and start all over.

Hi,
I wanted to update my Pixel C to the most current factory image with flashfire as i did it before a few times without problems.
So I DL'd current factory image from https://developers.google.com/android/images#ryu, opened it in flashfire and said it should flash the normal partitions except recovery as i don't want that it overwrites my TWRP.
Flashfire analyzed the zip file and after i said "flash" it restarted my Pixel into a black screen. At this point i was wondering that nothing more happened.
I waited for 10 minutes so that maybe something in the background could happen, but there was no further action. The screen kept black.
After these 10 minutes i restarted the device but now it always runs into TWRP directly instead of starting the system
I also tried to install the zip manually in TWRP but it tells me
"Could not find 'META-INF/com/google/android/update-binary' in the zip file.
Error installing the zip file '/usb-otg/ryu-n2g48c-factory-0bc0ee15.zip'"
As you can see from the error message i also tried to dl the file again and install it via OTG but the same thing.
If I go into the file manager in TWRP i can still access the folders from the sdcard.
The bootloader is unlocked of course.
Anyone an idea what i can do without loosing all the data?
Thanks in advance
Download the full system image and extract it. There should be a flash_all-file (bat for windows of sh for linux). Open it with an editor and remove the "-w" option in fastboot. "-w" is the switch for wipe. After you removed it, you can flash the complete image and your system should boot again into android. After that you can install a custom recovery, etc. again.
Thank you peter, worked like a charm for the system flash. Now follows the TWRP etc again
EDIT: ok, the system flash was the only thing that worked like a charm. I tried flashing TWRP with NRT but didn't work. I am stuck now at a "no command" screen when i start the device.
To install the custom recovery NRT tells me that i will loose all my data, so i wanted to backup everything.
Unfortunately i can't backup everything now as the temp booted TWRP demands a password to decrypt the sdcard, but i only have a pattern and no password set.
So now i try to flash everything again and to install twrp without loosing all the data.
Hey everyone I have flashed android 7.1.2 August again and android started afterwards without any problems. I was able to restore the backup of all the apps from Google.
Than I wanted to get back root and flashed TWRP with Nexus Root Toolset, but now only TWRP starts every time I switch on the tablet. Any ideas what I can do?
EDIT: I fixed it somehow with flashing the whole firmware package again and than the TWRP wich broke the startup again so i ended up in a TWRP bootloop. Therefore i flashed android again and TWRP 3.0.0.0 than TWRP 3.0.2.4 (something like that) and after like 3 to 4 different flashing steps it worked again. I have no idea what happened during the first flash of Andoir 7.1.2 but i think that something broke there.
I upgraded a couple months ago from 8.1 to 10. I ended up doing a full wipe ( or so I thought) through TWRP and flashing the 10 image. However, it seems that I somehow screwed up the encryption on my phone. I can boot the phone and put in my PIN to access and use the phone normally, but inputting the same 6 digit and my old pre-10 4 digit PIN into TWRP does not decrypt the phone and allow me to flash things. If I continue in read only mode in TWRP, I can flash but everything in my data partition has jumbled file names.
So my question is: Am I going to need to back everything up and wipe in order to fix this? Can I simply use Magisk to disable Force Encryption then decryp that way while keeping my data intact?
I would prefer using the simplest least painful way possible, but if I have to wipe to fix it then so be it.
Twrp decoding doesn't work for Q .. best to remove lock before entering TWRP
Also try "default_password".
Well I got impatient and ended up screwing up everthing.
Now I'm having trouble getting TWRP installed back on the phone. I have wiped everything, flashed the latest January factory image, booted to TWRP image, but when I attempt to flash the TWRP zip I get "failed to mount /system" and "failed to mount /vendor". If I boot back into the installed TWRP, I am not able to flash any other zips such as Magisk.

Disable your screen lock. Download twrp again to your pc. Put a copy of the twrp.img file on your phone as well. Fastboot into twrp, select instal, select image, go to your twrp.img,.select to install it to Recovery Ramdisk. You'll have to flash custom kernel and magisk again if applicable :good:
Hello There,
I have Redmi Note 5 Pro with unlocked bootloader. But unable to root it no matter what.
Let Me Explain The Situation.
1. After flashing TWRP, it asks for "decryption password" which is nowhere to be found on internet. But in order to decrypt it i had to format the phone. GOOD Now Storage is Detected in TWRP.
2. But if i boot phone in System and again boot it in Recovery then TWRP is replaced with Stock Recovery.
1 & 2 are in INFINITE LOOP now.
3. So OTG...... OTG is not even recognizing by TWRP, but OS is detecting it.
4. TWRP "Enable MTP" also not working.
So Let Me Know If I am Forgetting Something.
Please Help Me To Root IT.
PS : I have past experience of Rooting/ Flashing rom / Unlocking Bootloader etc.
I guess the main problem you're having is that your phone keeps replacing TWRP with the stock recovery once you boot into system. I've had same problem on different devices. To prevent this from happening you should not boot into system immediately after flashing twrp, rather you should boot directly into twrp recovery (try "fastboot boot recovery.img" command after flashing twrp - I'm assuming that your twrp img is saved as "recovery.img") and flash Magisk before booting into system. By flashing Magisk before booting into system your phone would no longer replace twrp, and then your phone would be rooted as well. At least that worked for me.
And also use orangefox rather than twrp on this phone
Hello,
I have a strange problem with Galaxy A5 2017 after installing twrp + lineage 18.1. I will explain the problem in sub points.
1) in January on stock software I installed (according to instructions from XDA forum) root, twrp (via ODIN) and bypass with memory decryption. Then I installed Lineage 18.1, Gapps, Magisk and debloater on it to remove unnecessary apps.
2) The phone worked fine until mid-April. Some update was installed and the phone died.
3) The phone wouldn't boot up after the update and only the TWRP logo was looping (logo kept flashing).
4) the phone couldn't boot up, but after I found the only way to get the system to boot up was to enter command "adb reboot bootloader" from windows console. The system booted, but after another reboot unfortunately it was the same thing - the TWRP logo was looping.
5) I managed to upload Lineage Recovery via ODIN, but unfortunately this didn't change anything. Phone was booting to recovery only (but it was working). I tried to update via ADB Sideload from recovery - also without success. Interestingly, the only way to fix it was to fully format with the system partition from recovery and re-upload the system. This worked, and Lineage booted into the android interface, but on the next reboot I unfortunately only had the Lineage loading logo visible for 10-15 minutes - then a reboot into recovery. I had to repeat the formatting and re-upload the system.
6) Interestingly, when I used the combination - lineage recovery, full format, twrp 3.6.1 (via ODIN) - TWRP booted normally and I could install LineageOS. The system would only boot once, and after the next reboot the TWRP logo would loop again.
7) The last problem I noticed is that if I load Lineage system, gaaps package and magiska via TWRP or Lineage Recovery, the system will never boot - either it will loop the logo (if using Lineage Recovery) or the phone will not load the system, it will reset and loop the TWRP logo indefinitely (if using TWRP recovery).
Does anyone know a solution how to restore the phone? Will it still work or for example NAND memory is dead and nothing can be done? Best regards
