After seeing another user on here (hopefully soft) brick their Maven 3 from trying to root using ZPST and the rooting guide here, as well as myself, I want to warn anyone else to not attempt to use any other tool other than the QFIL application from the Qualcomm QPST (the v2.7.480 should be good) software package.
QFIL can backup and flash any partition on the device, negating the need to use any other tool, including ZPST. I am not sure if it is enabled by default, but on the (new) Maven 3 board I have, the devinfo partition did already have the necessary bits for the bootloader to be unlocked (guide for that can be found here). I was able to successfully backup the boot partition (boot.img), put it on my device from my computer, then build a modified Magisk boot.img from the Magisk Manager app. With that, I flashed it as a boot.img partition and it works fine. I can write a full tutorial if there is interest.
But the most important information you should take from this thread is to backup all of your partitions before doing anything to the phone using QFIL. Once you do this, I don't think you can hard-brick your phone, as, if necessary, you can short two solder joints by the SD card slot (message me if you need a picture) to automatically put your device in a functional EDL mode in order to flash your original partition(s) back to the device.
do you have backup files for the phone, I can get into edl mode only. My backup file will not restore the phone

What partitions do you need? boot? I know there seems to be different bootloader versions and stuff

Hi everyone,
Without further ado, here is a guide to backup and restore your DS7 in nvflash mode.
Scripts where modified from existing scripts for another device. Thank you to whoever created it.
Note: be prepared, the output files are about 15 - 20 GB in size
Guide:
1. Prepare your computer by downloading this and extracting.
Removed for editing
2. Connect the DS7 in nvflash mode by powering off, holding down both volume keys (+ and -), and then while still holding down those keys plug the USB into your PC.
3. Open the folder downloaded in step one and double click the backup_DS7 file.
*Sit back and relax* This will take quite some time but after the script completes your DS7 should be backed up to that folder.
Now to restore simply double click the restore_DS7 file in nvflash mode.
Hope this helps out!
Please report any problems with my scripts on this thread
Files taken down until corrected as pointed out by The Manii below.
You realize that ICS, HS r2-r6 and stock 5xx roms all have different partition maps right?
Those bat files will only restore correctly 5xx -> 5xx backups as at best it will write images to the wrong spot. I dont believe it will flat out corrupt partitions, but it will definitely screw up ICS -> 5xx data restores as ICS uses the 5xx sdcard partition as it's data partition.
Repartitioning is a seperate step, at least with those scripts you can only repartition to 5xx but not away, and only if you had made a backup of a 5xx rom beforehand.
If you use --download instead of rawwrite you can make it backup and restore to the same layout, but it wont be able to cross restore/backup. But this leads back to it doesnt really do anything that CWM cant already do.
--download for both scrips will allow to backup and restore to the correct partitions then, only based on the ROM being backed up, correct?
I have taken down the zip temporarily until corrected.
As for the CWM function, with ICS flashing to different partitions CWM for HC does not work with ICS and vice versa so some people on the DS7 ICS thread wanted a way to backup and restore their devices that can be deployed without worry or issue.
Thanks for the pointers!
This is why we had a hard time with ICS because of the completely different partition mapping.
Cant see any download link, can u share it again thx
Hey folks! :victory:
So I know you're all going to say, "oh, it's some xda noob", but I've got some big ideas for the future. So I had this great idea for an app that I'd like to share with all of you. I recently had my phone (HTC One m7ul) hardbricked by a slip of my fingers while clean-installing Omnirom. Fastboot and adb could not detect it, and therefore, my computer couldn't be used in the process of attempting to restore it. However, I could still access my recovery; and this is where I came up with the idea for this app I think everybody should have installed:
STASIS
This app would be the savior of all those people out there with hardbricked phones.
HOW IT WORKS
The app installs itself into the preexisting legacy partition of your phone, where it lies dormant and safe until needed
The app then recognizes the installation process to be complete and prompts the user to clone their phone into "stasis"
The way it clones the phone into "stasis" works as follows:
It copies the system partition exactly as it is
It then prompts the user for which files/apps it should back up as well
It saves all the selected files and apps in an archive that it names as "Stasis.zip" and then compresses and encrypts the archive with a password of the user's choice
Once complete, the phone reboots itself
Your phone is now INVINCIBLE!
The phone can now be saved from a complete internal storage wipe via commands from the recovery menu.
HERE IS THE TRICKY PART
The only way that this archive can be installed from the recovery partition would be by somehow force loading an extra option in the recovery "advanced" menu or by making it mounted via a series of hardware button presses in the install menu of recovery or a command line. This is ALOT HARDER than it actually sounds.
Prior to your internal storage wipe, your phone can restore via recovery by entering the series of commands and/or hardware button presses to mount the TWRP partition, and therefore flash the stasis.zip.
POSSIBLE OPTIONS?
The stasis.zip could be stored in it's own partition private from the rest of the system and/or recovery.
NOTE THAT I HAVE NO EXPERIENCE IN ANDROID DEVELOPMENT
I just want to see this damn thing made so everybody can have their phone hardbrick and live to tell the tale.
:fingers-crossed:
--flq of xda
P.S. If anybody thinks this app is a good idea, please feel free to join up on it's github!
doesnt a nandroid backup works the same way ?
or similar?

Your phone wasn't even close to being hard bricked, you wiped your system partition and internal storage at the same time. Leaving you no Rom to install or Backups to restore. This is a soft-brick at best.
In the process your Windows drivers failed stopping you from pushing a Rom which I still don't know weather you sorted or not because you haven't replied in your other thread.
The app you describe would do nothing a Nandroid doesn't do already. And regardless of where you store the Stasis.zip/Nandroid if you wipe the phone it will be gone. There are only 3 flash partitions on the HTC One System, Data and Cache all the other partitions are RAW partitions that require a direct dump.
If you want a separate partition to keep a backup on that can be accessed without the need for a pc, get your self an USB OTG device. Then you can keep a backup or rom on a usb stick and copy it or restore it to your phone using OTG without the need for a pc.

What Danny said.
A hard-brick state is where you cannot access the kernel or even the bootloader. I'm not so sure if you still can access download or APX mode if you were hard-bricked, probably can still access either of them because it is most likely detached from the boot loader (again, not so sure, but from experience download mode *MAY* become inaccessable).
If your device was really hard-bricked and does not or cannot access any of those modes (I imagine fastboot being inaccessible as well) then all you can really do is JTag it. Problem is that devices like the Sony Tablet S has files which disables JTagging so I believe you have to directly JTag to the flash memory or something for it to work.
I think there is this other connector which can be used to also restore it, but I have forgot since I have not looked into it for a long time now.
I've forgot to mention, the recovery is also inaccessible in a hard-brick as it relies on the boot loader to change the boot path to the recovery or something (recoveries use a kernel as well).
Hello.
I'm having issues TWRP backups. Maybe I was undone system. I need a friend using the honor 7 PLK-L01 system backup of your phone by then compressed .zip TWRP.roi nk.len up for me to use. My machine is now no longer on the operating system.
*Help me.
thank you
There are many ways to bring your phone to life. But I can suggest this;
- Extract boot(if necessary) and recovery .imgs from a full rom(which one you want) via http://forum.xda-developers.com/showthread.php?t=2433454
- Flash them by adb commands
- Put the update.app file in your sd card and start the update by 3 button way
Another suggestion is more simple; use Multi-Tool to flash the stock recovery and that's it.

I don't know actually but md5 errors are usually harmless. But if your recovery is working, just do fresh installation.

Status phone rom I'm wrong. logo only lead to hang on is TWRP, connect PC and Fastboot. but when I rom stock (PLK-L01 C432B270) is successful but unable to reboot the operating system. H7 is due to the security, it's hard to be rescued. I also put it into the service center (not the local machine), they also confused with my H7. I need to find ways to revive it, no matter how well!
Hello J3 Pop users. I have here a "backup" of the PL1 firmware made using TWRP. This flash procedure may be necessary if one can not flash the Odin ROM because of any number of failures (there seems to be a common problem with this). I am not positive if this is stock, or pre-rooted.
If you're looking for an Odin file, check here https://forum.xda-developers.com/general/general/rom-pl1-samsung-galaxy-j3-emerge-sm-t3580396
First off, DISCLAIMER: This is not a factory approved flash method, and if you haven't done so already, may void your warranty, or brick your device. Use at your own risk.
Now, with that out of the way, you will need to install TWRP, if you haven't already. That can be obtained from this link:
https://forum.xda-developers.com/ga...overy-twrp-3-1-0-1-samsung-galaxy-j3-t3573607
Just follow the flash instructions, but you don't need to attempt to root it... that part might fail in this case anyways.
Download the file from this link. you will need to extract the folder inside to ".\TWRP\BACKUPS\{device serial}" on your SD card. If you don't see this folder, just create any kind of backup from inside TWRP, even just the "EFS" partition will create the folder you need.
With the files and SD card in place, select "restore" inside TWRP. Select the partitions to restore, and there are two partitions labeled with system, i would recommend restoring both. The "EFS" and "EFS2" partitions should never be restored unless you know beyond a shadow of a doubt that those partitions are corrupted (it rarely happens, even when a device is bricked).

Hello, a few days ago my zenfone started acting up (again), with built in applications crashing randomly and failing to boot half of the times. I always managed to fix it downloading the firmware from Asus' website and re-upgrate it, but this time it didn't worked out quite well. It now refuses to boot (sometimes gets stucked at boot, simetimes I manage to have asus screen). Booting into recovery prints `E:mount fail, change path to mount /dev/block/mmcblk1`, then errors about cache partiton not being found.
I've tried pretty much anything that would not result in data loss:
Wiping cache doesn't report errors, but doesn't help either,
Flashing stock boot.img and droidboot.img don't report error, but doesn't help either,
Flashing TWRP to recovery reports success, but I still get stock recovery,
Sideload fails coz it doesn't find expected mounts
Adb shell doesn't work as it can't find `/system/bin/whatever`
`adb pull /proc/partitions` returns what looks like a legit partitions list for mmcblk0 to me
Does anyone know what else I can try to rescue the data on the phone?

When you flash TWRP and try to boot into recovery, have you tried using adb with "adb reboot" command?
Have you tried the "fastboot boot twrp.img" command"(with the TWRP file renamed to "twrp.img")? If you can get that to work, you can temporarily boot a TWRP session and then use it to make a nandroid backup.
Have you tried creating an adb backup, as described in the link below?
https://forum.xda-developers.com/galaxy-nexus/general/guide-phone-backup-unlock-root-t1420351
If you have corrupted partitions, you might not retrive anything, you might have no choice but to use an option that wipes, repartitions and flashes the device.

thanks for suggestions,
adb backup doesn't work. It complains about /system/bin/sh not found (looks like either the partition isn't mounted or the failed update erased it).
fastboot boot doesn't work. I was messing with boot.img before, and I found out that intel's boot.img (my zenfone is x86) is not standard format. fastboot logs `creating boot image...`, I suspect it doesn't work at all for intel's. It reports 'booting OK' but the phone doesn't reboot at all.
fastboot flash recovery twrp.img returns OK but still stock recovery...

Thank you so much for helping me out with this, I spent over a week trying to fix/backup data, I was going to give up.
After backing up things properly I'll play with it, see if I can have it booting again (maybe not stock system ).

Be careful, this tool is built to work on a lot of different devices with different hardware and different partitioning, the differences in partitions means that it cannot create or restore nandroid backups on all devices that the tool can boot on. Some intel devices that this tool works on can create and restore nandroid backups, some can't, it just depends on how the device is partitioned. It can also be used to flash ROMs on some devices but not on others.
This tool can boot a temporary recovery session on a lot of devices but not all of them can use all of the features in the recovery that it boots.
This difference in partitioning means that trying to restore a backup or flash a ROM can break some devices because the partitioning isn't right. So just be warned, you will be exposing your device to a certain amount of risk if you try using all of the features in the temporary recovery session.
Also, this tool was designed to boot a temporary recovery session on intel devices that have a locked bootloader, this recovery session can not flash ROMs on intel devices that have a locked bootloader, it can only be used to flash devices that have an unlocked bootloader. If your bootloader is locked, you'll brick your device if you attempt flashing a ROM on your device using this recovery session.

Thank for your concern, I've backed up contents of the sdcard and data partition (other partitions fails to mount) to an external SD. Ofc sdcard contents are just copy/pasted, as for data partition I've checked and looks like I can open the twrp archives from linux. I'm gonna try to clone the whole mmcblk0 before trying anything weird tho .

You might can modify the tool itself or the TWRP .img that is built into the tool to modify it to work with the way that your device is partitioned, that way it mounts, reads and writes those partitions correctly.

I've tried to use the twrp for z00d I have previously downloaded, I have to do some tweaking to make it boot. Even tho it looks like a newer version, console is crashing and partitions won't work anyway. Since stock recovery fails to mount cache I guess there's corruption somewhere on the device. I might have found the stock partitions.tbl, but if I manage to clone mmcblk0 to an external sd, I can perhaps mess with the image with linux and confirm whether is there's corruption.

Hello, I've tried a few more stuff today, by the looks of it, the device silently fails to write anything.
I've tried to use adb push to flash a fixed image to /dev/block/mmcblk0, tried fastboot flash, tried dd from the recovery, even tho it reports ok, nothing is actually written on the device. I've tried to rename a file in data (which does mount), but after unmounting/remounting the partition the file still have the old name.
Maybe I can try loading a system on the external sd instead, but that's it.
Thanks again for your help, I was able to recover the data which was actually my priority.
EDIT: partition command also fails
