[Q] OTA Update failed to install correctly. Recovery missing...

Yesterday, the OTA update was pushed to my D3 by verizon. It appearred to install correctly, but I noticed issues with a couple apps. I tried to enter recovery, but it's not there! I checked /system and it is full. 0 free space. I need to reinstall the recovery. Any help would be appreciated.
UPDATE: I rooted my D3, and then pushed the recovery to the phone. I then ran the install .sh and was able to boot into recovery.

I have the same issue. Update installs (Thanks to Petes tools for bloatware recovery) but camera app is not working. Try to boot into recovery and get this message:
Code:
AP Fastboot Flash Mode (S) (Boot Failure)
0A.53
BAttery OK
OK to Program
Transfer Mode:
USB Connected
Invalid CG Version (CG:recovery)
Based on suggestions here I used Titanium Backup to backup and remove a few verizon bloatware apps and got up to 54MB free on recovery partition, but still can't boot into recovery. Tried doing an adb push of the install-recover.sh from the update to /system/etc and still can't boot into recovery. When I run sh /etc/install-recovery.sh I get this:
Code:

I do not really know where to go from here. Because I haven't yet posted ten times, I can't respond directly to the thread where they were discussing this solution. Any help would be greatly appreciated.

I pushed recovery-from-boot.p and install-recovery.sh files from an update I downloaded from another thread. I ran the .sh from terminal on the phone, and it installed the recovery partition. Did you push both files?
recovery-from-boot.p is located at /system/recovery-from-boot.p

Thanks a lot! This seems to have worked. I ran the install-recovery.sh from an adb shell and am able to boot into recovery again. Now I just have to reinstall all the bloatware and run the patch again.

[Q] Problem Installing Roms

I've tried installing various custom roms (and versions) and they all seems to fail. The only successful flashes I've managed have been stock roms from this page. This is the log from when I attempted to install CM 10.2 in TWRP 2.6.6.3:

CM10 is really old are you sure that's what you want ? and it may require a special version of recovery .. check the developers thread
[QUOTE]First time installing CyanogenMod 10.2 to your HTC One (GSM), or coming from another ROM:

TWRP 2.6.3.3 and Philz Recovery 6.25.0 are the only recoveries I've managed to get working

Yeah, I'm not sure what's up with that. But it's for sure the reason why the other roms aren't working

When I bought the phone(supposedly brand new) the bootloader was locked but it was already S-OFF and had CID:11111111. The writing on the box is in German(I live in New Zealand) so I guess whoever I bought it off had fixed that for me...

Just in case anyone ever stumbles upon this thread in the distant future, let it be known that I managed to install this rom successfully and it's got all the useful features you'd expect from Cyanogenmod (and a few more).

This is the exact same problem I have only the 2 recoveries you mentioned work for me too, I've tried updating to newer versions of TWRP but it gets stuck on the HTC Logo with "entering recovery" at the top, I have the international version I also had to replace the screen because it smashed maybe that has something to do with it.

Tried looking around the forum but haven't found a solution yet
I'm on a huawei g7 using android 4.4 rooted

Still no solution. I tried finding a way to manually install the app_process but i can't find any tut on it

So i think every file on /system is write protected to i tried to unlock it with
su
mount -o rw,remount /system
cd /system
chmod -R -i *
But i didn't work :/

oke so i tried to run the installer one last time tonight and for some reason it installed the framework without problems. i have no idea why..

Run the following commands in a terminal emulator:
Code:
su
cd /magisk/.core/magiskhide
sh disable
sh enable
You're probably gonna get an output that the hidelist can't be created because of a permissions issue. That probably means the Magisk image doesn't get mounted properly at boot.
Another user (@gunner007dc) that had this issue fixed it by using a different kernel.

If you type just:
Code:
su
mount
and look for a line that starts something like:
Code:
/dev/block/loop0 on /magisk
In the parenthesis at the end of the line, the text should start with "rw". Does it?

Hm... I have no idea...
From your earlier posts I assume you've already uninstalled and reinstalled Magisk a few times, right? Have you tried an unofficial beta snapshot (both Magisk and the Manager)?
I still say you should try a different kernel. I don't know what you mean with "supports systemless root", but I'd try flashing a kernel like Elemental over the one that comes with RR and then install Magisk. Maybe even try installing and running Kernel Auditor, like it says in the link I posted earlier.

what is the difference between systemless xposed and the normal one ? (cuz both got caught by safety net)

It's very likely the Xposed Magisk module needs to be updated to work with v13... I don't use Xposed though, so I wouldn't know.
The difference between system and systemless xposed is that one is installed into system and the other one is systemless. :laugh: Seriously... That's the difference. They'll both trigger SafetyNet. Systemlessness is not about passing SafetyNet.

You're probably gonna get an output that the hidelist can't be created because of a permissions issue. That probably means the Magisk image doesn't get mounted properly at boot.

No idea. I can't see your device and I can't read your mind... Meaning: you've given very few details.
I'm gonna make a guess though: are you taking about the ".core" folder? It's a hidden folder, so if your file explorer isn't set to see hidden files and folders you won't see it.
If this is not your issue, give more details.

How to patch `system.img` to root the Samsung S10 5G (Qualcomm) device?

Hi All,
Device Detail:
- Samsung S10 5G
- Qualcomm Device
- Model: SM-G977U
- ROM: VZW-G977UVRU2ASH7-20190827135903
- Kernel-Version - Linux version 4.14.83-16633035 ([email protected]) (clang version 6.0.10 for Android NDK) #2 SMP PREEMPT Wed Aug 14 16:23:48 KST 2019
Background: I have
- rooted the device with instructions given by Magisk.
- I can successfully reboot to the recovery rootfs.
Problem: I am trying to modify the `system.img.ext4.lz4` file to root the device with normal boot. I am aware that it will not let the device install OTA Updates.
Unpack-Pack System and make new AP.tar, flash:
- Without any modification to the `system.img`, I have just unpacked `system.img.ext4.lz4`->`system.img.ext4`->`system.img`->mounted to system directory and packed it back to `system.img`->`system.img.ext4`->`system.img.ext4.lz4`.
- Replaced unpack-packed `system.img.ext4.lz4` with the AP `system.img.ext4.lz4` and make a tar of it.
- Then I have flashed it using Odin v3.13 along with BL, CP, and HOME_CSC.
- Odin has show PASS and I have rebooted the device into recovery mode.
- Done the Wipe data/factory reset and reboot to recovery again but released the recovery key combination on splash screen as mentioned in the root instructions .
- The device stuck in a boot loop.
Tries:
1. Disable Dm-verity
- Removed `avb` flag from `boot.img` with
Code:
magiskboot dtb boot.img patch
- Removed `avb` and `verify` flags from `dtbo.img` with
Code:
magiskboot dtb dtbo.img patch
- Patched `ramdisk.cpio` with
Code:
magiskboot cpio ./initrd 'patch false true'
Patched `boot.img` and `dtbo.img` is working fine with magisk patched AP file but the `ramdisk.cpio` creating the issue: Stuck at splash screen when trying to go to recovery after successfully flash with Odin. Download mode is appearing on splash screen.
So, I have used `boot.img` and `dtbo.img` along with unpack-packed `system.img.ext4.lz4` but the result is still a boot loop. I have also tried a combination of `boot.img` and `dtbo.img` along with unpack-packed `vendor.img.ext4.lz4` and flashed the AP.tar with other files but still the result is a boot loop.
So, I want to debug the problem and got to know about `pstore` which preserve the logs when kernel panic.
2. pstore
- Checked that `/sys/fs/pstore` is mounted by the system with following in init file: Grep the pstore using `find . | grep '\.rc' | xargs cat | grep pstore -n -i` and get following result:
Code:
314: # pstore/ramoops previous console log
315: mount pstore pstore /sys/fs/pstore nodev noexec nosuid
316: chown system log /sys/fs/pstore/console-ramoops
317: chmod 0440 /sys/fs/pstore/console-ramoops
318: chown system log /sys/fs/pstore/console-ramoops-0
319: chmod 0440 /sys/fs/pstore/console-ramoops-0
320: chown system log /sys/fs/pstore/pmsg-ramoops-0
321: chmod 0440 /sys/fs/pstore/pmsg-ramoops-0
- Checked the kernel config by pulling the file from /proc/config.gz.
Code:
$ cat config | grep PSTORE
CONFIG_PSTORE=y
CONFIG_PSTORE_ZLIB_COMPRESS=y
# CONFIG_PSTORE_LZO_COMPRESS is not set
# CONFIG_PSTORE_LZ4_COMPRESS is not set
CONFIG_PSTORE_CONSOLE=y
CONFIG_PSTORE_PMSG=y
CONFIG_PSTORE_PMSG_SSPLOG=y
CONFIG_PSTORE_RAM=y
- Check the `ramoops` configuration:
Code:
./sys/module/ramoops/parameters/console_size 262144
./sys/module/ramoops/parameters/dump_oops 1
./sys/module/ramoops/parameters/ecc 0
./sys/module/ramoops/parameters/ftrace_size 262144
./sys/module/ramoops/parameters/mem_address 3241148416
./sys/module/ramoops/parameters/mem_size 1048576
./sys/module/ramoops/parameters/mem_type 0
./sys/module/ramoops/parameters/pmsg_size 262144
./sys/module/ramoops/parameters/record_size 262144
`pstore` setup looks fine but when I am trying the get logs from `sys/fs/pstore` then I found nothing.
I have tried it by two ways:
1. Crash manually with panic kernel using:
Code:
echo 1 > /proc/sys/kernel/sysrq
echo c > /proc/sysrq-trigger
Followed Reading Kernel Logs
2. Flashing non-working rom that cause a boot loop and then flashed a working ROM with rooting steps and checked the file at `sys/fs/pstore`.
I need a favor in:
- Any steps to fix/debug the `pstore` problem?
- Any other way to find the kernel logs?
Update 1: I get the logs from recovery but I am not able to identify the problem.

Description: In this video, I have done the following:
1. Displayed recovery logs before: The last recovery logs are ends with 8.
2. Rebooted the device with a recovery key combination. I have already wipe data partition before making this video.
3. The boot loop happens and in the next reboot, I have pressed the recovery key combination to open the recovery mode where logs that end with 9 displayed.
4. Then I have recorded `last_history`, `last_avc_message_recovery`, `last_log.9` and `last_kmsg.9`
5. `last_history` and `last_avc_message_recovery` looks unchanged(same as before boot loop).
6. Then, I just have tried to mount the system but that didn't work.
7. At last, I have just rebooted the system normally without any recovery key combination.

Is anyone have experience in detecting problems from the kernel logs?

i can not help you, but we can collect ideas. what about re-sign the system.img? there is a key somewhere, i guess just deleting won't work but maybe it is possible to calculate checksum

or maybe you can switch to SuperSU 2.79 SR3 (latest release from chainfire) or at least look inside the update-binary shell script how to root system.
regarding dm-verity i would start with searching for "verify" flag in your fstabs and remove it. magisk is also doing some hex patches and re-signing, it's the best source to look inside magisk installer zip update-binary/ updater-script, if you have the knowledge to read code
another option is try to port a twrp recovery from another snapdragon (i wonder if somebody did this already) if you can find a porting guide

dunno.. its not possible on n976v..

Was there any luck on rooting the Verizon G977U?

@Vats12 has already successful rooted with magisk in recovery. this thread is for rooting system (kind of rooting where su binary is placed in /system/xbin like for older devices, which breaks OTA)

Yes, do you know how to do this?
Magisk (guide) does a lot of other things too..
Maybe we can use Magisk to disable the securities and then SuperSu can help in the rooting system?

model see OP! i guess because of the buttons needed for booting in magiskrecovery, but the reason is not important only HOW (for Vats12, not for me i don't own this device)

Sorry but this thread needs to be closed

I don't want to be the one who shouts fake, but the instructions you gave a link to says you have to be able to flash a bootloader first, which means an unlocked blootloader, if you have Verizon rom this is not possible, as the blootloader is locked.
If you did find a way to flash a modified bootloader, or a modified recovery those are the instructions we need, because in fastboot you are unable to do this with a locked bootloader and you are unable to unlock the bootloader on Verizon. If you have a modified bootloader or recovery flashed on your device what did you use to flash it with Odin? Because only way to flash a boot.img is either get into download mode and flash with Odin, or with Edl, if you got into edl mode then can you provide instructions on that, because we would like to know how to get the device into EDL mode as well
Sorry boys this is a hoax.

@DroidisLINUX there is video proof in OP, and again for you:
This is not a tutorial about unlocking and rooting, it is a question how he can modify /system to permanently integrate su
