Hi:
G6 recently found that many of the latest version of 2.2 can not brush, I've been busy. Did not have time to study, today look. Give us a solution;
1. download attachments extract me get flash_image and mtd0.img files. Will flash_image and mtd0.img data into the phone directory
Done processing the two documents, if you want to study without change the consequences, because such documents and the ROM is not related to the contents of which are hboot
Attachment to China GOAPK forum need to download, in this community I do not have permission to post links,
Sorry
Go bbs.goapk.com/thread-46408-1-1.html download.
Running inside the terminal
point to obtain permission to enter su, enter: chmod 755 / data / flash_image (or chmod ux / data / flash_image)
/ data / flash_image misc / data/mtd0.img points carriage return,
If no error, then see the # symbol, and then restart after the ROM during the Brush 2.2
2, if the newcomers do not know how to put data directory can be placed on sdcard is the sd card root directory
Obtain permission to enter su, then enter
cat / sdcard / flash_image> / data / flash_image
cat / sdcard/mtd0.img> / data/mtd0.img
Then enter chmod 755 / data / flash_image (or chmod ux / data / flash_image)
Finally, the input / data / flash_image misc / data/mtd0.img
Operation every step of the command when the attention of the space I have written, or will not succeed.

You want to download this version "Root_with_Restore_by_Bin4ry_v32: [New Root for Z1 14.1.G.1.534]" http://forum.xda-developers.com/showthread.php?t=1886460 Sometimes it takes a couple times.
Make sure you have ADB enabled on your tablet as well as "allow install of applications from unknown sources." I always like to set the screen time out to never when doing modifications.
I run Windows 7 64bit and it works fine.
Hi to everyone.
I was updating my tab to the latest version of the ROM of sbdags.
Everything was fine until i reboot the tab to use it for the first time: loop in the boot animation and never come out from it.
I came from the previous version of the rom, the Cromi-x 6.1 with 10.26.1.18 bootloader.
The process i use to update was this:
1) wipe of data/factory reset, wipe with format /boot, wipe with format /system
2) Install the CWM recovery 6.0.5.0 and update the bootloader to 11.4.1.17 by flashing they with the file that you can find in the rom page.
3) repeat point 1
4) install the rom by flashing it from an SD. Complete the Aroma installer and answer to every option that it ask to me.
5) reboot the system and stuck in the bootanimation
I use the WW format cause i'm italian and i check the md5
What's wrong? I can go to recovery everytime i need and i have a backup just in case i need it.
Sdbags, i really want to offer you a beer for your work. I think i will do it in every case, but yes, kitkat on my tab would be great :victory:
Sorry for bad english. For every question, i'm here. Thanks a lot.

That log is fine - everything is installed.
Read out the bootloader version from the bootloader screen to double check please.
Also you are rebooting after installing the bootloader and cwm package aren't you?

Right and then you boot back to CWM, do a full wipe (you may need to wipe your internal sdcard so back it up first) and then flash the rom. After that it should boot fine.
If not please search xda for how to get a logcat and post one of it bootlooping please.

I try the first thing that you say but nothing, still loop in bootanimation.
I'll do a logcat through adb in the afternoon. Now i had some problem cause i can't mount usb storage through cwm for some reason. Late i'll find drivers or what's missing.
Maybe can help: when i reboot frequently cwm ask me if i want to fix root. It's normal?
Thanks you for your help.

i've some problem to find the SKU code. I search on the box of the tablet but there are too many codes and i don't know what's the right. Can you give me an exemple of it?
Yes, i can restore to 4.3. In this right moment i'm writing with the tab with cromix 6. Everything seems to work fine.
In case like this you really know how much important is to do a backup..

SKU is just your country code - so if you have changed it it could be causing issues with the clean install.
US, WW, TW, CN, JP are the only 5 I know of.
So if you changed the bootloader from US to WW I heard another user reporting some issues.
But in your case I am at a loss as to how you can boot 4.3 but not 4.4.2 as you are apparently on a 4.4.2 compatible bootloader and recovery .......

Ah, right, i understand. I am WW, and i use it in every installation that i've done on my eee pad, from the rooting process and the unlocking of bootloader to the change of the rom.
Now that i am on the previous version of your rom those are infos of kernel, firmware, ecc.

In ROM Manager i can see that my Recovery still is the 6.0.5.0 version.
In bootloader i can see that it is "WW_epad-11.4.1.17-20140711"
Hope that this might be helpful and hope that i don't write anything of unsafe.

NO that is expected but hat is not expected is why you can't boot 4.4.2. Let's wait for _that and lj50036 to cast their expert eyes over your issues.

Ok, so maybe now i need some help.
I run adb in my pc then i type adb shell to run the remote shell interactively.
Then what i need to type?
Anyway if i type "ls -l /system/framework > framework.txt" the response is "No such file or directory"
Sorry for my n00b questions. Really hope to learn something here, and give a chance to reward everyone for the help.

The commands were supposed to be typed as is on your computer. However I think I missed to quote the "echo $BOOTCLASSPATH" - I want the bootclasspath of your device, not of your PC.
Anyway, if you type "adb shell" first and then "ls -l /system/framework" and you get back "No such file or directory" that's strange...

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

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
Device: X2 Pro
When I flashed stock rom with twrp, it read:
"Mount: failed to mount / dev / block // bootdevice / by-name / userdata at / data: Device or resource busy"
It's still done, but I need to format data and wipe it to boot, otherwise it will go into twrp.
When flashing magisk file also has the line:
"dtbo image: / dev / block / sde17"
It still completed, but could not be booted up. I have to flash the stock rom to boot again.
I cannot root my device, please help me.
Thanks!
