[R&D][UNBRICKING] - Thread for trying to solve the OTA brick problem

Intro
Someone contacted me because of my work unbricking Amlogic tablets and sent me their bricked Nexus 7 2013 32GB Wifi version tablet. I have the same tablet and I’ve been exploring unbricking options and looking at the devices. I have not found a solution yet but I have found a lot of interesting things. I worked on several models of Ainol's AML8726-MX SoC tablets and unbricked them in from various states, including having no signs of life and jumping some pins on the nand chip to get it recognized by the computer. Some tablets had similar problems to the Nexus when the bootloader was corrupted from a bad flash. The internal memory showed as zero in TWRP and the tablets wouldn't boot into the system. Checking debug logs showed the memory chip was not initializing. The Ainol tablets don't have a bootloader with a GUI but they did have a external SD card slot, so the tablet could boot from the SD card and run a "rescue flash". If that didn't work, Amlogic also had low-level USB Burning software to write to the tablet, although special files were needed and flashing was tricky.
I don’t know if we will be able to fix the Nexus tablets with this problem or if they are even fixable with the tools available but I’m providing all this information because I’m working on the problem in my spare time and maybe other people want to experiment with their bricked devices as well. There are a couple obvious routes to explore, one being Qualcomm's QPST and QFIL software, as well as other similar software programs for these chips, like the BoardDiag Tool. Another option is try and boot the tablet from a "rescue card" like I used for the Ainol tablets but to do it through an On-The-Go cable. Even if we don't unbrick any tablets, if anything, at least this thread might provide some documentation on the Nexus 7 2013 that doesn’t seem to be available elsewhere. I’ll keep updating this thread with new info and links to drivers, software, documentation and relevant websites. I’ll post what I’ve updated into the “Updates to this thread” section.
The problem
OTA update bricks device and we get one of the following scenarios:
Users can enter fastboot but can not flash, format or erase anything. Trying to start the device or boot into recovery gets stuck on the Google screen with the lock icon.
Same as above but when entering a recovery like TWRP, device hangs on the TWRP logo screen.
Users can not enter fastboot. Plugging the device into the computer shows QHSUSB_DLOAD in the device manager
Users can not enter fastboot. Plugging the device into the computer shows Qualcomm HS-USB QDLoader 9008 in the device manager
Users can not enter fastboot. Plugging the device into the computer shows Qualcomm HS-USB Diagnostics 9006 in the device manager
In 9006 mode the storage shows as Qualcomm MMC Storage USB Device in the Device Manager
---
Trying to flash or format in fastboot returns the following error:
Code:
FAILED <status read failed <Too many links>>
I’ve figured out a way to boot into TWRP and have started collecting logs and other information about the problem. I’ve also figured out the majority of fastboot oem commands which I’ll list below. The device is not initializing the MMC card when it starts up. In dmesg we can see the error:
Code:
mmc0: error -110 whilst initialising MMC card
Where on a working device we see:
Code:
mmc0: new HS200 MMC card at address 0001
mmcblk0: mmc0:0001 MMC32G 28.8 GiB
In the TWRP log we see:
Code:
[COLOR="Red"]E: Could not mount /data and unable to find crypto footer.
E: Unable to mount ‘/data’
E: Unable to recreate /data/media folder.[/COLOR]
Updating partition details…

MTP Enabled
Trying to wipe partitions or flash in TWRP fails because the card isn’t mounted at all and the partition table isn’t being read. Everything is running in the RAM and the only filesystems mounted are rootfs, tmpfs, devpts, proc, sysfs, selinuxfs and tmpfs.
Checking the partition table in fastboot using “fastboot oem gpt-info” does return the same results as a working device though. When booting into TWRP we can see “Nexus 7” as an MTP device but there is nothing on it. In Qualcomm’s 9006 Diagnostics mode we can see the device under disk drives in the device manager as Qualcomm MMC Storage USB Device but it doesn’t show up in Qualcomm’s 9008 Download mode. In disk management we can see it as an Unknown 28.81 GB Unallocated Disk. We can see the same thing in MiniTool Partition Wizard but neither Windows or MiniTool can initialize or format the disk. In HDD Raw Copy Tool the device shows as Qualcomm MMC Storage with a capacity of 30.93 GB. I was unable to write a RAW image of mmcblk0.img using HDD Raw Copy Tool, getting the error “Write Error occured at offset 0 (1)”.
My Working Theory
Looking at both the most recent reports of the OTA brick and past reports, it seems like the problem occurs when there is a bootloader update packaged in with the firmware update. It is possible that the eMMC chip is fried because we've seen bugs in the past but I'm working on the assumption that it is not since the chip is recognized, shows the correct capacity and gets registered it in by the kernel. We can also see that persistent_ram has an uncorrectable error in the header and no valid data in the buffer. This could mean a bad eMMC chip but it could also mean the parts of the bootloader are gone or corrupt. It could also mean the GPT is bad.
We can also see that the device is always booting into ttyHSL0 mode which is the UART Serial Console mode for debugging. I don't know a lot about Qualcomm architecture but I do know that there are several modes including diagnostics, download and emergency download mode. It's possible that the tablet is stuck in one of these modes. I read though some Qualcomm documents and it mentions using the NPRGxxxx.hex file to flash your device but it also mentions that, if the chipset supports it, changing the name of the NPRGxxxx.hex file to eNPRGxxxx.hex "allows you to download new images to a mobile device that has an empty or currupt flash device." That function was implemented in 2008 though and I'm unsure if the implementation has changed at all.
Getting Started
I’m not going to cover any of the basics like installing ADB and Fastboot on your computer. This thread is intended for people who already have a working knowledge of using these tools and want to try and work on the bricking problem. If you are don’t have that knowledge and would still like to experiment with your bricked device you can find lots of tutorials on XDA on how to install and use ADB and Fastboot.
I will mention a couple of things I ran into though. Since I hadn't been working on tablets for a while I wasn't able to use ADB in TWRP at first. I noticed that it only worked if I disabled MTP in the TWRP menu. However, updating the Android SDK solved this problem and the updated drivers allow both an MTP and ADB connected at the same time.
There may also be times when you need to disable Windows Driver Signature Verification to be able to install unsigned drivers. Here is a link showing how to do it temporarily. There is also a way to disable it permanently which I think is to run the Command Prompt as Admin and type:
Code:
bcdedit -set loadoptions DISABLE_INTEGRITY_CHECKS
bcdedit -set TESTSIGNING ON
Lastly, you'll probably want to stop Windows from automatically installing drivers for new hardware. You can do that by right clicking on your computer and then going to "properties -> advanced system settings -> hardware -> device installation settings -> no let me choose what to do -> never install driver software from windows update". There are also guides with screenshots on how to do this if you Google it.
---
We can get into a recovery like TWRP by using the fastboot command:
Code:
fastboot boot twrp.img
If booting into recovery fails and the you get stuck on the TWRP logo screen then go back to the bootloader and use the fastboot command:
Code:
fastboot oem reset-dev_info
---
To enter Qualcomm HS-USB QDLoader 9008 “download mode” you can hold down all three hardware buttons when the device is powered off and plugged in. You can also power down the device, hold the Vol+ and the Vol- buttons and then plug in the device. To enter Qualcomm HS-USB Diagnostics 9006 “diagnostic mode” you can press the power button repeatedly then wait around 30 seconds and see if it connects in the device manager. I don’t know what the speed you are supposed to press the button is but it seems to take at least 10 presses, sometimes more. You’ll have to test it out until you get used to doing it.
Tasks
Want to help out? Here are some things I'm working on. There's a good deal of research to do, so even if you don't have a working device you can help. If you have a device that you've totally given up on and are pretty much going to throw out but can still get into the bootloader, test those fastboot oem erase_ commands before tossing the tablet. It will be fastboot oem erase_"partition name". An example is fastboot oem erase_aboot. Just run through them and write down which ones work and which ones don't.
If someone with a bricked tablet has UART off in the bootloader and can boot into TWRP, please check "adb shell cat /proc/cmdline" and tell me if "console=ttyHSL0,115200,n8" is in the commandline. You can check if UART is on or off in the bootloader by using "fastboot getvar all".
Look into other APQ8064 devices to see if files relevant to QPST work. There is a list of devices below that have the same SoC but not the 1AA or FLO tag at the end. Its possible some of these files might work well enough to at least get the memory recognized.
Pull partition table from a working device and format it in partition.bin or partition.mbn for use in QPST.
Try to write partitions pulled from working device back to the tablet in fastboot.
Format partitions from a working device as .mbn files for QPST.
Pull first few raw GB from a bricked tablet and examine it to see if there is data present. If there is then it might mean that those partitions are corrupted and we can focus on writing working partitions back to those location. Try with RAW copy tool and with dd.
Testing QPST software to resurrect the device. Will need more files first, need to structure them as .xml files necessary for the software.
Test "fastboot oem erase_" on other partitions.
Test "fastboot flash" of partitions that aren't normally included in a firmware update, like sb1.img, rpm.img, aboot.img, etc.
General Device Info
Here is a spreadsheet with all the partition info that I've pulled and sorted.
The Nexus 7 2013 is an APQ8064 1AA/FLO Snapdragon 600 series device that is advertised as a S4 Pro. The APQ8064–1AA is the WiFi version and APQ8064-FLO is the LTE version. The ASUS MeMO Pad FHD 10 ME302KL LTE also has the same SoC according to wiki. The platform board is listed as MSM8960 in most of the code.

fastboot help
Regular fastboot options that might be useful
-c <cmdline> override kernel commandline
Add -c followed by a kernel command. If more than one kernel command is in the line then they should have parenthesis around them like this "console=ttyHSL0,115200,n8 androidboot.hardware=flo". This is used for the "fastboot boot" command to boot into a kernel with different commandline parameters. Here are the kernel commandlines listed in /proc/cmdline:
Code:
console=ttyHSL0,115200,n8 androidboot.hardware=flo user_debug=31 msm_rtb.filter=0x3F ehci-hcd.park=3 androidboot.emmc=true androidboot.serialno=049973d5 bootreason=PowerKey fuse_info=Y ddr_vendor=hynix androidboot.baseband=apq asustek.hw_rev=rev_e androidboot.bootloader=FLO-04.04
-i <vendor id> specify a custom USB vendor id
Add -i and then the vendor id you want to use. The Nexus 7 vendor id is 18d1 and Hexidecimal Syntax is 0x18D1. Fastboot wants the Hex value:
Code:
-i 0x18D1
-b <base_addr> specify a custom kernel base address.
I haven't done this in long enough that I've forgotten how to use it. The default is 0x10000000 and the BOARD_KERNEL_BASE is listed as 0x80200000 in the Nexus code.
-n <page size> specify the nand page size.
The default value is 2048. Add -n and then the value you want to use:
Code:
-n 2048
-S <size>[K|M|G] automatically sparse files greater than size. 0 to disable.
I've never used this. If anyone has any insight, let me know.
fastboot oem commands
I extracted the aboot.img and used Notepad++ to look at the commands. I’m not sure what the variables are for some of them but I’m working on testing some things out. This is how how I figured out “fastboot oem reset-dev_info” would allow “fastboot boot twrp.img” though.
Code:
fastboot oem unlock
fastboot oem lock
fastboot oem device-info
fastboot oem memtest_
fastboot oem gpt-info
fastboot oem fuse_blow
fastboot oem check-fuse
fastboot oem reset-dev_info
Code:
fastboot oem erase_
Usage is erase_<partition name>. I've only tested it on persist so far. I'm assuming this is for partitions that aren't supported by the regular "fastboot erase" command.
Code:
fastboot oem erase_persist
Code:
fastboot oem off-mode-charge 1
fastboot oem off-mode charge 0
fastboot oem uart-on
fastboot oem uart-off

Reserved for if there is ever a solution.

I extracted all the partitions in RAW format today. I'll add some more detailed info here in the near future on how I did it but I used software called DiskInternals Linux Reader.
-----
Update: The info on how to make a full RAW backup of the entire device without having an external SD card to save it to can be found in this thread. I made some adjustments for the Nexus 7 and I did it all in Cygwin.
To make device backup in Cygwin and TWRP open a terminal and do this:
Code:
adb forward tcp:5555 tcp:5555
adb shell
/sbin/busybox nc -l -p 5555 -e /sbin/busybox dd if=/dev/block/mmcblk0
Then open a second Cygwin Terminal and do this:
Code:
adb forward tcp:5555 tcp:5555
cd /nexus
nc 127.0.0.1 5555 | pv -i 0.5 > mmcblk0.img
You can then mount the image you pulled with DiskInternals Linux Reader. It will show you all of the individual partitions, all of the unllocated gaps between partitions and some info about each one. You can open the EXT4 partitions like /system to explore them and you can also open the radio.img and see everything inside. You can then save all the partitions as individual images. This method doesn't work with the bricked tablet. I'm building a spreadsheet with info on all the partitions.

I pulled them all from a working device so I can try to write them back to the bricked device but also so I can try and make the flash programming files for use in QFIL. On another note the bricked devices can show up in the Windows file manager as a single small partitions with a list of files. I found out today that those files are the contents of the radio partition. I have a folder with those files from a bricked and working device now and I'll do a hex comparison to see if they are still all intact on the bricked device. That also means the FAT partition at the very beginning of the eMMC chip is still there and working, so the whole chip isn't "dead".

Hi fuser-invent,
Thank you for your job.
Do you have any solution to write a stock rom to flash memory ?
Lollipop OTA bricked my Nexus 7 2013. Several people reporting this problem.
I can't unlock bootloader and adb sideload not work.
Thanks.

Still working on it but my job suddenly got really, really busy. Hoping to get back into it after the holiday rush. I wish there were other people trying to work on this problem too though.

I just received a new Nexus 7 on 5.1.1
It isn't bricked but when I flash TWRP it shows all the unable to mount errors in your first post and I can't access the sdcard. When I use the TWRP option to boot to system it says there's no OS installed but it does boot into android. I flashed the 6.0 img without any issues. Still the same problem with TWRP.
I've never had any issues like this before.

Have you tried the multi-rom TWRP that fixes the mount point problems?

No, I wasn't aware of that until you mentioned it.
Thanks for the suggestion. I'll give it a shot when I have a chance. Should probably fix it since apparently the devices that shipped with 5.0 have the issue.

I've the same issue and used the Multirom to workaround, but what about ROMs that say "use the latest version of TWRP" ?
If this is a software-caused problem, has the Android team been notified with a bug report or something?

As owner of 2 N7 2013 devices, one of them bricked, I would like to thank you for your work and time.
I find this thread very instructive and I think I will try to follow the leads you provided and try to get my device back to life.
Alas, much study is needed on my part!
I also found some info that may or may not be useful here:
github.com/aureljared/unbrick_8960
I hope I can find and share something useful, and wish you all good luck!

N7 2013 32GB Bricked
I look forward to doing some testing my self with this tablet... Problem is, my bootloader is locked and I can't unlock it since it won't format the internal storage... can't even boot into TWRP because of that.
Anyway, I'm very interested in using DD to flash the partitions at some point if that's available. I can also get into download mode, so using the qualcomm utility to write that way. It's just sitting here, waiting to be revived!

Following the instructions above, I could get to the point where I have the partitions of the working device.
I can also put both devices in 9008 mode, and the bricked device only in 9006 mode also. Although windows registers it as diagnostic mode, QPST is reading both 9008 and 9006 as Download Mode, and does not allow me to backup the working device.
So, as far as QPST goes, I'm kind of stuck.
But, reading what I found in github.com/aureljared/unbrick_8960 I might still have a chance: I just have to understand how to set up the files that are needed though...
Wish you all a good day!

But, reading what I found in github.com/aureljared/unbrick_8960 I might still have a chance: I just have to understand how to set up the files that are needed though...
Wish you all a good day!

I think we need to build our own flashing files using aureljared's method. I have a ton of partitions and data ripped. I'll try to upload it soon so everyone has access to expirement with.

Yes, I think so too. Also considering the fact that those scripts are much more understandable than a closed source program, even to me and my scarce knowledge.
Just a thought: why try and rebuild the partition table and then copy each partition in its place? Wouldn't it be much easier to just "dd" the working device in one single file and then "dd" it back on the bricked one?
Of course, IF (and only if) the hex and mbn provided by aureljared succed in switching the device into Streaming Protocol and let us actually write to memory.
If there's anything I can do, I'll be glad to do it.
Have a nice day!

unbrick LG G2 Force Flash with Send_command.exe

Use it if you cannot flash with any flash tool (no root needed)
Note: Use this at your own risk! Use it as a last resort!
I'm not responsable for anything, this may not work with yours
Sorry for my poor english. I tested this method with MY bricked LG F320L, no root, no boot, no many partition pop up, partial
downloadMode (just download mode and can't see the USB logo nor S/W update) then can't flash with KDZ/TOT file,with adb mode
recovery when holding pwr and vol+ ( lucky ), with stock recovery but I have to write adb reboot recovery to get it
what you need (sorry, I'm too lazy to put a direct link, I found all of them in xda):
- Install driver for your device
- .kdz file of your model
- WindowsLGFirmwareExtract-1.2.5.0-Release
- Send_Command.exe and ports.bat (ports.bat is optional if you know the port where your device is plunged can be in LG_root.zip)
This methode needs that you can access to downloadmode or partial downloadmode like me (vol+ and plug USB cable)
1- Run WindowsLGFirmwareExtract
. browse your .kdz file with "Open" button
. click to "Extract KDZ" button and wait until finish
. browse the .dz file abd extract it with the appropriat button
. click to "Extract DZ" button and wait until finish
. select all system files and clic Merge system-bin (you will get system.img in another folder and you don't need all system****.bin)
. copy all files in same folder
2- change extension of all files .bin to .img and remove any numbers
example: aboot156.bin => aboot.img / 1-aboot.bin =>aboot.img
3- Push or copy all files to your device. You have to find also the laf.img of your device, sometime it's not in the KDZ file.
Maybe it's optional, but I'm not sure.
Remember the path, for this tuto I'm using adb and push all files to /data/local/tmp/
You can also copy all files with another method
4- Run Ports.bat
Double click ports.bat (This will give us the COM port in which our device is connected we are looking for the Diag port)
keep in mind the COM of \Device\LG*******DIAG*
5- Go to downloadMode
6- Run send_command.exe in command prompt
type: Send_Command.exe \\.\COM3 if COM3 is the port where your device is pluged
wait for #
flash all .img like this, replace NAME by the name of the file ex: aboot.img replace NAME by aboot
dd if=/data/local/tmp/{NAME}.img of=/dev/block/platform/msm_sdcc.1/by-name/{NAME}
ex: dd if=/data/local/tmp/aboot.img of=/dev/block/platform/msm_sdcc.1/by-name/aboot
Except for backupGPT.img, I don't know what is it. Maybe in this partition:
dd if=/data/local/tmp/backupGPT.img of=/dev/block/platform/msm_sdcc.1/by-name/gpt
personally , I have not flashed this one
If you have finished type: LEAVE
Flash completed

Thank you guy, your tuto saved my device

@santatralalaina
I'm in a similar situation like you. No download, fastboot or recovery and phone is not detected by Windows. As u said PARTIAL Download mode only. I'm not very good with adb also. Could you please guide me about force pushing of the .img files please! Where can I get send command.exe and ports.bat? Could you please attach some screen shot of Step:6. Renaming the file and command is bit confusing for me.

Hi, Don't panic! Take a deep breath.
Firstly: What is your phone model?
Secondly: What happen when you plug your phone to your PC?
Finaly: What you have did to try unbricking you phone?

Hi..thanks for the reply....My phone is G2 F320L..Korean version with removable battery and SD card....I tried to install a non compatible ROM..got bricked with only fastboot...Then I try to flash aboot.bin..boot.bin..laf.bin..etc files (which I have extracted from the kdz) through fastboot...during flashing my phone was disconnecting and connecting back again...thats where all the problem started I guess. Now I dont have fastboot also. If i connect my phone to PC.. LG logo comes on the phone screen...on PC it try to detect as LGE android MTP devices and try to install the driver of the same. But the driver installation fails eventually.... At windows device manager it show as LGE Android MTP devices with error code 10...and showing connected to port:COM3....If I try to get in to the download mode..it get stuck at the (.............) download page...it is not going to the page with big USB picture...
My thinking is...Since the device manager is showing that it is connected at COM3.....Can I force flash the boot.img, aboot.img, laf.img etc files with "Send command.exe?
At least I can try to force flash right? If it is possible..may be I will be able to enter in to the download mode:fingers-crossed: Right? Where can I get this "Send command.exe" and how it works?

Hello,
It was easy to unbrick the fastboot but now... ok, you are stuck in LG LOGO but after no black screen? can you charge you battery? And if you try to go to RecoveryMode, what's happen? do you have multiple partitions and QHSUSB_DLOAD trying to be instaled? It's also easy to unbrick the QHSUSB and if it is the case, don't use send_command to flash manualy your device.
Maybe, you can force flash. You have to find a solution to push all .img files to your device. If you cannot use ADB, try to put the img files to sdcard.
you can found send_command.exe and ports.bat in this zip file, it's an utilities for having root on LG G2 :
LG_Root.zip
you can use all root command with it!

Hi!
As I known, LG G2 is unbrickable
This method is for last resort because I havn't complete documentation about this!
I've tested it with my own LG F320L only
Try to flash with TOT files or LGUP
Try to repair the download mode http://forum.xda-developers.com/showthread.php?t=2706590
Try to force the QHS_USB to appear then use the appropriate tools http://forum.xda-developers.com/lg-g2/general/file-unbrick-qualcomm-9006-qhsusb-t3056800
Try send_commande before shorting testpoint (it's less dangerous IN MY OPINION)

I just wrote and shared my experiences. Forcing the qshusb by shorting the right pins in the motherboard is the only solution if you cannot push the img files to your phone with adb, by sdcard, by MTP or something else

[Guide] [Unbrick] How to revive a hard bricked Moto G5

This guide is for hard bricked Moto G5 Cedric
Hard bricked means a device which can not enter bootloader mode normally
This method has now been confirmed working
Works with XT1672 XT1670 XT1671 XT1675 XT1676 XT1677 (and most likely all others and if you ask if it will work on your version I will just copy & paste this to you!)
Smaller Image
Thanks to Luka Panio, Omega, and nift4 we now have a smaller image size
Goto This github page and under assets download mmcblk0.img.gz
Extract mmcblk0.img from the zip file to PC
Previous Larger Images
Mega
Download mmcblk0.zip image from Mega
Create your own mega account and import the file into your mega account. Log into your account and download it from your own account
Extract mmcblk0.img from mmcblk0.zip to PC
Or for those of you who can't use mega or have unstable Internet I've split the large file size into smaller multiple zip files. You must download each part and then extract using an unzip tool like winrar or 7zip
Android File Host
Download mmcblk0.zip mmcblk0-part1.zip and mmcblk0-part2.zip from Android File Host
Extract mmcblk0.z01 from mmcblk0-part1.zip
Extract mmcblk0.z02 from mmcblk0-part2.zip
Extract mmcblk0.img from mmcblk0.zip (If prompted point to mmcblk0.z01 and mmcblk0.z02 but it shouldn't ask if all files are in the same folder)
Requirements
Freshly formatted microSD card 16gb if using the smaller image or at least 32gb if using the previous larger images (It needs to have at least 31.3gb free after formatting - if it displays as less you will need to buy a 64gb microSD card or use the smaller image)
7zip
Linux mint live usb/dvd
USB card reader
Method
The BEST method to flash the sdcard with mmcbk0.img file is to use LINUX!
Windows users have no need to install Linux on their PC, you can run Linux from a bootable usb-stick that is at least 8gb or a dvd
Do not run Linux as a virtual machine on Windows! Use the live USB/DVD
0) Put the Moto g5 on mains charge until you have finished flashing the sdcard so it's fully charged ready for the boot test!
1) Run Linux, preferably cinnamon or mate versions of Linux Mint
2) Insert the sdcard in pc or card reader and open "Disks" app
3) In "Disks" app select sdcard and you will see the sdcard partitions
4) Press "-" to delete the partition (delete all partitions if there is more than one)
5) Press "+" to create a new one and name it mmcblk0, set FAT(FAT32) file format and press "CREATE"
6) Press "Play" button to mount the sdcard, look to see what path the sdcard has (/dev/sd??) and then close the "Disks" app
7) Go to Desktop, open "Computer" and navigate to the location where the img file is extracted (mmcblk0.img)
8) Open the window where img file is with root (right click on window and select "open as root")
9) In root window open the Terminal (right click on window and select "open terminal")
no need to type "su" in terminal, it has root already (see notes if using Linux live usb/dvd)
10) Type in terminal the command written below and don't forget to eliminate that "1" from the sdcard path,
that "1" can make the difference between the phone booting or not!!!!!
Things to note
Linux Live dvd doesn't have open as root so just open in terminal and add sudo to the start of the commands
I've included this in the commands below
If you get a status error just remove status=progress from the terminal command below
Terminal comands
- if your sdcard is seen like " /dev/sdb1"
in terminal apply this command:
Code:
sudo dd bs=4M if=mmcblk0.img of=/dev/sdb status=progress oflag=sync
-if your sdcard is seen like " /dev/mmcblk0p1"
in terminal apply this command:
Code:
sudo dd bs=4M if=mmcblk0.img of=/dev/mmcblk0 status=progress oflag=sync
and the flashing process should start
When it finishes, test the sdcard in the phone and it should boot!
If you get a size error of the sdcard in terminal you have to change the sdcard and try again!
Thanks to @vaserbanix for the original version of this guide
Re-flash Stock Firmware
Once the phone is in bootloader mode you can flash stock firmware via fastboot
Note that in order to flash gpt the firmware MUST be the same or newer than the version currently on your phone
Firmware can be download from Here
Once you have firmware that is the same or newer than your current version you can remove the sd card and run these commands (assuming you have fastboot all setup on your pc)
If you get a security downgrade error when you try to flash gpt.bin or bootloader.img then the firmware you are trying to flash is too old!
Code:
fastboot oem fb_mode_set
fastboot flash partition gpt.bin
fastboot flash bootloader bootloader.img
fastboot flash logo logo.bin
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash dsp adspso.bin
fastboot flash oem oem.img
fastboot flash system system.img_sparsechunk.0
fastboot flash system system.img_sparsechunk.1
fastboot flash system system.img_sparsechunk.2
fastboot flash system system.img_sparsechunk.3
fastboot flash system system.img_sparsechunk.4
fastboot flash system system.img_sparsechunk.5
fastboot flash system system.img_sparsechunk.6
fastboot flash system system.img_sparsechunk.7
fastboot flash system system.img_sparsechunk.8
fastboot flash modem NON-HLOS.bin
fastboot erase modemst1
fastboot erase modemst2
fastboot flash fsg fsg.mbn
fastboot erase cache
fastboot erase userdata
fastboot oem fb_mode_clear
fastboot reboot

I might consider doing this if you explained what this loader.img is?
Is it something one would flash to recover their G5?

Potentially - its used to boot off the sd card so those with a bricked phone can access the bootloader through booting it off their sd card & then flash the firmware via fastboot
See

Thanks for uploading it

Hello, I followed all the steps of the link, using a 16gb card and the file here hung and nothing, the phone does not start.
In my case it is an xt1676 which only turns on the led and blinks when I connect it to the pc by usb or the wall charger.

I take it the programme wrote the loader image successfully to sdcard
So either the person who uploaded the Loader.img interrupted the extract & so its corrupted or this phone can't boot off the sd card with this method
It does say it may take a while to boot but who knows

If anyone else can upload a Loader.img using the methods in the first post so there's a comparison please do

Yeah right.
What is strange to me, although maybe it is, is the size of the file hung here, 165 mb.
the 16gb card is formatted in fat32, is it correct?
Does the DiskImageRev2 program automatically create the card to be bootable?
Why install the qualcomm drivers if the phone does not have to be connected to the PC? It is assumed that the phone will boot in bootloader mode and there only need the adb / fastboot controllers.
I do not mind to keep trying since the phone I give for lost at the moment.
Can someone return to the first post with an xt1676?
Thank you.

Yeah right.
What is strange to me, although maybe it is, is the size of the file hung here, 165 mb.
the 16gb card is formatted in fat32, is it correct?
Does the DiskImageRev2 program automatically create the card to be bootable?
Why install the qualcomm drivers if the phone does not have to be connected to the PC? It is assumed that the phone will boot in bootloader mode and there only need the adb / fastboot controllers.
I do not mind to keep trying since the phone I give for lost at the moment.
Can someone return to the first post with an xt1676?
Thank you.

I presume it's needed for some devices who use different methods of flashing stock firmware
Someone else has uploaded an image file so you can try that one from a xt1677
Yes formatted fat32 - you should just have to select the drive the sdcard card is assigned to on your pc in the program eg f: and then select image file & then write - and accept the warning
It should make it bootable
Iv no idea if this method will work with this device

then it does not work in this model or the file posted here is wrong. Because I have done it as here is exposed and nothing.
I'm going to try the one from xt1677

So either the person who uploaded the Loader.img interrupted the extract & so its corrupted or this phone can't boot off the sd card with this method
It does say it may take a while to boot but who knows

Hmm, there haven't been any error messages on my side. I pulled the image again with above dd-command. I also tried with adb shell instead of terminal emulator but it's always the same file with the exact same file size.

I assume the file is correct - it's probably more the case of this phone doesn't support this method
If I get my hands on this device again in the future I can properly test things but at the moment all I can do is throw out ideas for people to try
Think I'll leave it now as without the device there's not a lot I can do

nothing, it does not work. it does not start :crying:
As I said, only the LED flashes when connected by USB or charger.

I recommend using rufus for flashing it to the sd card, it has never failed me yet, and supports up to 16gb.
Edit: I have the XT1675, if anyone would find it useful for me to post this variant's bootloader then I'd be happy to do so.
Edit again: Isn't dd used for writing an image to flash storage for later booting rather than extracting it?

It seems, some qualcomm devices need a full mmcblk0 dump to be able to boot from sdcard (e.g. LG G5)¹. I don't know if thats the case for our device but you can give it a try:
Loader_XT1676.zip Uncompressed filesize: ~4GB
¹ "The Loader method requires a full ROM Dump also known as a full blk0 backup of a working LG G5 H850 correctly flashed or written on a pretty good and fast class 10 SD Card."

dd basically clones/copies the source-data block by block to another disk, partition or (img-)file.

Thanks for the info - if someone can try this full Loader.img & let me know if it works I'll write up a guide

Iv added the guide to the first post if people want to test
Like Iv said before I no longer own this device - I have not tested this & it may not work
Feel free to add potential solutions to help those with bricked devices

Refer to this guide for root. It's free.
(ROOT) ZTE Blade Z Max Z982 Free Non-UAT 2/21/19

My phone is B25 Not B20. Do you got one for my specific firmware?

The patched boot and recovery are from b20. They are working fine on my b25 system image.

Any ideas how to get the UAT for free?

Here is the MetroPCS B25 full partition update.zip designed to be flashed via recovery

Here is some early production firmware use at your own risk
https://www.androidfilehost.com/?fid=11410963190603910729
Pulled these from a paid site to update my device, and maybe get a firehose for you guys in the process but no luck.

After you flash your phone will try to boot. It probably will probably boot loop. The reason being, your current system in encrypted. So here is a list of what you have to do next.
1. Disconnect your phone from the computer.
2. Press and hold Vol+ and power until the phone restarts and vibrates. Then release power while continuing to hold vol+.
3. You will boot into TWRP. Swipe to allow modifications.
4. Select Wipe
5. Select Format Data
6. Type yes and then blue checkmark.
7. Back out and select reboot then system.
Mission Accomplished
The phone will do a the intial setup and you will have to open magisk manger which will then prompt you to install it.

why not using [adb reboot edl] command to boot directly into edl mode instead of using zte tool.

It seems from what I could find online the file we need from uni is called 8936_020.ufl
I'm not 100% certain though

I think we have to make one.
https://cellphonetrackers.org/wp-content/uploads/8x60_msimage.mbn_.txt
How to generate the 8660_msimage.mbn
8660_msimage.mbn is released in SW by default, actually, it includes the all the boot images and partition table there. MPRG8660.hex will download this image and reset to mass-storage mode. If customers have different HW settings, such as GPIO/DDR, the default 8660_msimage.mbn may not work for them, so customers need build their own 8660_msimage.mbn by themselves with following ways.
1. Have the QPST 2.7.366 or higher version installed.
2. Make a local folder, copy sbl1/sbl2/sbl3/rpm/tz images to this folder.
3. copy the emmcswdownload.exe from C:\Program Files\Qualcomm\QPST\bin to this folder.
4. Prepare the partition_boot.xml as below and copy the partition_boot.xml to the same folder as above.
<?xml version="1.0"?>
<image>
<physical_partition number="0">
<primary order="1" type="4d" bootable="true" label="SBL1" size="1000" readonly="false">
<file name="sbl1.mbn" offset="0"/>
</primary>
<primary order="2" type="51" bootable="false" label="SBL2" size="3000" readonly="false">
<file name="sbl2.mbn" offset="0"/>
</primary>
<primary order="3" type="45" bootable="false" label="SBL3" size="1500" readonly="false">
<file name="sbl3.mbn" offset="0"/>
</primary>
<primary order="4" type="5" bootable="false" label="EXT" size="1000000">
<extended order="1" type="47" label="RPM" size="1000" readonly="false">
<file name="rpm.mbn" offset="0"/>
</extended>
<extended order="2" type="46" label="TZ" size="1000" readonly="false">
<file name="tz.mbn" offset="0"/>
</extended>
</primary>
</physical_partition>
</image>
5. Run the emmcswdownload.exe tool to create OEM boot image with a command below.
emmcswdownload.exe -f 8660_msimage.mbn -x partition_boot.xml -s 1G -g 4M
6. The 8660_msimage.mbn will be generated in the folder.

Additionally, I dumped the usb packets going from uni to my phone while flashing splash.img. It has the loader and the splash.img in it. But it needs to be pulled out. If anyone is capable, try it. uni_usb_dump_z982.7z

The firmware you provided only have Sbl1, it doesn't have sbl2 or sbl3. Can you help me? And one more thing do you have root on your Z982 because I think I found where the firmware is in the phone and we can copy it and keep it. I can't do it because it gives me access denied of course I don't have root but I think a person with root can do it.

The Z982 has 1 sbl. "SBL1"

Did you already root your phone?

Yep

Can you try something for me real quick? Plz
