[H815] I think I screwed up my phone's software

Edit:
I installed some LG Drivers from a root article and now the phone is recognized. I can update to V20G and test it again, hope it works!
Hello!
I was running CM14.1 on my LG G4 and a few days ago I decided to install a new update but from within the phone itself. Sadly, it just rebooted to the recovery and didn't install anything. And from there, it always rebooted into the recovery no matter what I did. I also did a full wipe and installed CM14.1 clean but it still rebooted to the recovery and didn't want to go past that. I made a Reddid thread - https://www.reddit.com/r/cyanogenmod/comments/5gcap3/g4_h815_cm_141_help_i_cant_boot_outside_of/.
So I got help with that - I got into Download Mode and flashed the stock software via LGUP. Sadly, after I did this, I can no longer install a custom recovery. The phone is not rooted and LGUP and LG Bridge don't recognize the device anymore and the phone says there isn't a new update available but it's on the 5.1 stock ROM.
Whenever I flash the TWRP image via fastboot and I reboot into recovery, it doesn't boot into TWRP but it boots into some kind of other fastboot mode. And I've tried to issue `fastboot boot twrp-x-x-x.img` but it fails to do so and shows `FAILED (remote: dtb not found)`.
Is there a way to fix this so I can flash CM again?
Thanks in advance!

The bootloop to recovery is a known issue of one the December nightlies of CM 14. Head over to the CM thread and search for bootloop and twrp. They provided a solution to solve this too.
Besides that: which twrp version do you tried to fastboot? H811 or h815? Taken from the official download site?

twrp-3.0.2-1-h815.img, H815 as the title says and from the official website as I've always done. As for the thread - I don't have TWRP and I can't even flash it as I've written in my post. That's what I'm struggling with.

Flash ROM - i'm going crazy here!

Hi,
i have a Helium 128G and got some problems with the radio. Currently i was on 8.1.5 following the guide
http://forum.xda-developers.com/mi-max/how-to/guide-install-global-miui8-root-t3435594
and i also officially unlocked the bootloader after this.
So i thought - to flash a new radio - it would be fine to just flash the 8.1.9 over the updater method. Unfortunately the phone rebooted in TWRP and flashed something. After this the reboot took >10 Minutes so i rebooted into TWRP and found the internal storage is encrypted now. So all data lost. Great!
Nevertheless i tried to flash 8.1.9 via Mi Flash. This worked and the phone booted but after i flashed TWRP it won't boot anymore. What is this? Is it even possible to run 8.1.9 rooted with twrp?
Thanks for your suggestions, i'm really pissed at the moment
EDIT: My TWRP Backup with 8.1.5 worked and now i have the radio from 8.1.9 and the rom 8.1.5. Nevertheless i would like to have 8.1.9 rooted with twrp

Hi! I've also experience your problem, did your phone entered recovery mode after flashing TWRP? if not try flashing the 8.1.2 ROM through EDL (power+vol up+vol down) then after letting the first boot finish flash TWRP. Hope this help

I'm not sure but at one point i saw the xiaomi recovery picture!? Now it works with my 8.1.5 backup again but is it really that heavy to just install a current version when on twrp and root!? i'm officially unlocked for that.

Can't upgrade TWRP from 2.8.7 to 3.0.2

Hi, I flashed the FOTA Kernel with TWRP 2.8.7 onto my phone and inside TWRP I flashed the recovery with the 3.0.2 TWRP image (telling me "Successfully flashed")
But after rebooting I still have TWRP 2.8.7
Using windows command line and "fastboot flash recovery "TWRP.....img" I get this "FAILED" message.
What am I doing wrong?
I even flashed the phone back to stock and then followed these instructions but same result.
Is my phone broken or sth?

Hi H4NNE5, the Xperia M does not have a recovery partition. The TWRP recovery is included in the boot partition when flashing the kernel. Try to upgrade with the TWRP-Manager if your phone is rooted.

Hi Lightningsfire, Thanks for you answer.
Ok, that's weird because I read a lot of threads but none said anything like that. I'm more confused right now.
Anyhow the LineageOS is not properly working on my phone anyhow so I set it back to Stock Rom and check back in a few months if it improved
One more question:
So if I flash the whole software package the boot partition is overwritten then, right? Because I noticed that the Recovery was a different one, after I flashed the system.

Try this command
fastboot flash boot twrp_name.img

[SOLVED] [Zenfone 2 ZE551ML] Cannot boot into ANY recovery (corrupted partition?)

Device: Zenfone 2 ZE551ML (WW Z00A)
Current Firmware: UL-Z00A-WW-2.20.40.206-user
Bootloader version: unknown + unlocked
I've seen several tutorials about using fastboot to flash recovery back to normal, but nothing seems to be working for my device. For context, I played around with LineageOS and Mokee for a while until I decided to go back to stock firmware. I had TWRP working, so I just downloaded the original stock, formated all partitions with TWRP and reflashed UL-Z00A-WW-2.20.40.206.
That worked well, but I just realized I am unable to boot into recovery. Everytime I use adb reboot recovery, the device goes into a bootloop. The ASUS logo shows up, then recovery silently fails to load, and finally the phone reboots. This keeps going until I force the device to turn off and reboot into normal mode.
I can adb reboot bootloader and use fastboot to flash recovery images. I have tried several stock recoveries I found in the forum and blog posts. I also tried a recovery.img extracted from the official ASUS firmware package (UL-Z00A-WW-4.21.40.352-user). I also tried different versions of TWRP, most recent and one that was working on my device. No matter which one I flash, the device just won't reach recovery.
I am willing to flash the stock fimware back to the phone and recreate all partitions, if necessary... except I can't even do that because... well... I can't get into recovery!
Does anyone have any tips for a manual fastboot flash of the entire firmware? Can I somehow format and recreate this partition?
I'm thinking about improvising from the steps outlined here, but I just want to make sure I'm not missing anything.

Quick update: after house into the night, I found a way around it!
I eventually came across this post, which has links to a complete list of all Z00A firmwares in RAW format. So I could get a hold of the latest stock firmwares for Android L (2.x) and M (4.x).
Turns out, a RAW image is just a zip file. It's different in the sense that it contains several *.img files that compose the firmware in state ready to be flashed using tools like fastboot. Inside WW_ZE551ML_2.20.40.206_20170627.raw I found a recovery_sign.img, which I was able to flash and use successfully. Great! That recovered the original stock recovery.
After that, I was able to update my firwmare to Asus's latest android M. Strangely enough, I also reflashed TWRP after that and it also works again.
Hopefully, this can help any lost soul in the future.
Best regards to all!

Hello, My Zenfone 2 model Z00AD has stopped at recovery screen and can't get into TWRP. I have used fastboot flash recovery followed by fastboot boot for various img files including 9 of 12 TWRP image files available for this phone. I have tried the recovery file that you obtained from RAW files, but it did not work for my phone.
Any suggestions welcome!

Moto G7 play (XT1952-1) - please help with TWRP install ....

Hi, I got myself an used Motorola Moto G7 play (XT1952-1) with Android 10 Stock update (Build QPYS30.52-22-8-9) and just can't successfully install TWRP on it. What I did:
- Bootloader unlocked
- TWRP temporary loaded with fastboot (fastboot boot twrp.img)
- In TWRP 'Iinstall' selected the matching TWRP .zip and it said it was installed in both slots a and b.
But then, when I select 'restart to bootloader' and try to launch recovery, I get a bootloop (black screen with (N/A) in the top left corner. The OS as such still starts normally. So I guess the main problem here is the bootloop when trying to launch recovery...?
I tried installing over booted TWRP with unmodified boot.img and with Magisk patched boot.img, same result. The G7 play does not have a separate revovery partition, recovery is included in the boot.img
I used the TWRP files (EU) and instructions from here:
Motorola Moto G7 Play
Disclaimer:Team Win strives to provide a quality product. However, it is your decision to install our software on your device. Team Win takes no ...
twrp.me
My stock firmware is XT1952-1_CHANNEL_RETEU_10_QPYS30.52-22-8-9_cid50_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml.zip from here:
lolinet mirrors - firmware, software, iso etc.
lolinet mirrors - powered by h5ai
mirrors.lolinet.com
Am I missing something? I've now searched for days (most info is outdated, taken from other places/Motorola phones with just 'G7 play' added, or is ambiguous); so can anyone *PLEASE* help me? Does anyone have a G7 play of the same type with Android 10 Stock who has successfully installed TWRP and was able to access the Recovery afterward without being stuck in a loop?
I also can't create a TWRP backup with a fastboot booted TWRP because system (and internal SD too) seems to be encrypted, and I don't seem to be able to deactivate this in the phone. Is this normal? Some places say that TWRP can decrypt when it's installed permanently...
Or could anybody patch the boot.img in above Firmware and add TWRP for me so I can just flash the boot.img?
Thanks in advance... please reply noob-friendly.

Still need a patched boot.img? Attached you'll find a boot.img with TWRP installed. I followed your links to get boot.img + twrp.img.
NO MAGISK INSTALLED!!!​Please patch before flashing if Magisk is already installed.
I put a log of the repack command into the zip that is showing the checksums of the boot header. Just to have a proof.

Thanks for trying to help, but this boot.img behaves exactly like the one I made by following the installation instructions on the TWRP website. I flashed it, restarted bootloader, then tried to go into recovery, and it bootloops (black screen with N/A in the top left corner).
But what I need is a boot.img with a WORKING TWRP recovery (that can actually be launched when recovery is selected...
Any idea why this won't work, why TWRP won't start?

@Alonso_Quixana Try the attached one. It's a boot.img patched with twrp + recovery_dtbo. The recovery_dtbo is part of the twrp.img but TWRP's installer.zip doesn't take it into account while repacking the patched boot.img. Maybe (hopefully!) that's the reason why you're able to boot TWRP but not to install it permanently.

Please try also - in any case! - the patched installer.zip that comes with a recovery_dtbo.

Sadly, you can't flash TWRP on stock ROM, in case you did sucessfully, ROM will not boot and that can cause SIM and VoLTE issues, i did flash it on mine and now VoLTE doesn't work on my phone, you can only boot it in case you want to flash an custom ROM, flash it then reboot into recovery to install GApps on the Custom Recovery that the ROM does install, but since all of the ROMs are arm64, i don't recommend it since you will have constant app restarting when changing from one app to another app

I've seen so-called tutorials on Youtube where someone actually succeeded in installing TWRP on his Moto G7 play (but did not mention which Android version was on the phone), and the TWRP developers too claim that their version for Moto G7 play would work, it even got an official update for Android 10 (alas they never reply to direct e-mails, those snooty guys)... some on XDA even said the flashing of a 'dirty port' worked for them. Were they all mistaken? Or did it work on Android 9? Are all XDA threads and internet posts / Youtube videos misleading / lying?
Are you REALLY sure that there is no way to install TWRP on a Moto G7 play (to be able to create a working backup of the encrypted data partition)? A 'full restorable backup of everything' is what I need...
I'm not sure about Android 10 Stock Rom, but it seems to be a 32bit system on a 64bit Kernel?

It's a 32bit system on a 64bit CPU (Snapdragon 632). That's not unusual for Motorola devices. Open a terminal app and execute uname -a.

I think it only works on certain Moto G7 Play variations or even only on Android 9, also, another way to install TWRP is installing an Custom ROM then flashing an flashable zip of TWRP_11 by SyberHexen on Custom ROM's Recovery
Link to TWRP_11 Flashable Zip

In my case, flashing TWRP, even by following some tutorials made my MetroPCS Moto G7 Play to stop booting and also, VoLTE stopped working, fortunately, i had an EFS backup to restore my IMEI
Android 10 Stock Rom is an Arm (32 bits) ROM, every Custom ROM i tested are Arm64, but i don't recommend any of them since you will get constant app rebooting and notification problems since this is an 2 GB RAM device
