[PROJECT] Real Unbrick for hard-bricked Moto Z Play (addison)

Welcome everyone!
This project has started, becouse we need real solution for the problem. The problem of hard bricked Moto devices. It is like a curse.
When my device bricked I have done solid research, I have gathered many informations and files essential to revive my cellphone but 5 years experience of linux, rooting, compiling kernels and roms weren't enough to make it work.
But nevermind. I am even more determinated and I am asking ALL of You guys here to help me. Together we will come to solution.
Here is what I got, happy reading :
DICTIONARY:
PBL - Primary bootloader of the chip - this is like BIOS for phone so it checks chip for damage and problems and then it tries to load SBL but if SBL is corrupted or checksum doesn't match, PBL invokes Qualcomm HS-USB QDLoader 9008 emergency mode. PBL is hard flashed into SoC and can't be corrupted by firmware.
SBL - Second stage bootloader wich is more advanced than PBL. It initializes phone hardware and ABOOT.
ABOOT - Application bootloader (HBOOT). You probably know this one well. Android botloader.
Full mmcblk0 backup - Backup of whole phone flash storage byto to byte.
blankflash - method of repairing msm phones in 9008 state
programmer.mbn - Special type of software programmer that is being sent to chip in Qualcomm 9008 emergency mode. There it comunicates with pc via firehose protocol. Each phone has set of their own programmers, they are unique to phone and other programmers don't work. These programmers are signed so tampering it results in not working one.
firehose protocol - it is used to tell programmer what operations it must do on chip.
singleimage.bin - this package contains instructions for programmer and set of files it need (for example to replace)
gpt_main0.bin - Partition layout
rawprogram0.xml - instructions for programmer
patch0.xml - I don't know yet
STAR.exe - Application for managing and editing contents of singleimage.bin aka blankflash files
QPST - Flash tool from Qualcomm it basic function is to handle blank-flashing in a better way, also it allows for in-depth debugging of the process
Qualcom Premium Tool - Program made by Mppg Myanmar that is capable of making unlocking bootloader, OEM locks, making backup/restore of chip firmware, handling blank-flashing in VERY specific way (creating instructions for programmer), reading eMMC structure from firmware (can generate gpt layout so very useful!!!), modyfing FW and removing Xiaomi account. It also contains ALL programmers

INFO:
1. What causes the brick
I bet 100$ that you hard-bricked your Moto Z Play by installing OTA updates after downgrading firmware. This is only known reason for me at the time of writing this. There is most probable reason why it happens, look:
There are two most common chips on which smartphones are built - Qualcomm and Mediatek. While Mediatek chips are "modification friendly" and simple, Qualcomm chips are somewhat more advanced and have many features that can be enabled or disabled during prorammming in factory. One of them is PBL signature checking. During programming of your phone, proper signatures of SBL are written to it. When someone tries to override default SBL with the new one, it checksums are compared with that stored. If they match, new one is flashed, if not, then update does not happen.
Ok, but what it has to do with brick?!
I explain:
1. You decide to downgrade your firmware
2. During flashing, everything goes "well" (Phone boots), but trully update is partial:
FW in chip is (obviously) more recent that the one you downgrade to, and SBL signature is different (updated), so when it is compared to the signature of SBL from FW you want to flash, it don't match. That don't rise error and flashing continues. Only partition that stays untouched is bootloader, but all other partitions get replaced by those in FW zip. SBL is still compatible with the new partition offsets and partition layout overall so phone functions normally.
3 When OTA is executed, it checks the version of currently installed firware. The most reliabe way to do it is to check checksum of SBL which is pretty logical becouse it's checksum is like "fingerprint" of firmware. Normally, if it would detect the old firmware, OTA would be stopped, but newer SBL tricks it and OTA installs anyway.
4 Results are horrible, becouse OTA does not check GPT table and flashes partitions in bad sectors, corrupting FW.
This causes bootloader to go into Qualcomm HS-USB QDLoader 9008 safe mode.
5 Viola! Hard brick!
2. How to fix it?
That is jolly good question! What we have to do is to reflash full chip firmware. Suprisingly I see some solutions, but those need to be developed:
A) SD-BOOT
It turns out that our fancy chip can probably boot from SD-CARD! The procedure works like this:
- When chip starts, one of the very first things it does is loading the memory, so it can actually work. The trick, is that chip loads it from specific disk, marked with exact name (I don't remember which, but I will do research). Speccially repared SD-CARD can appear with that name, so chip boots from it, not from internal memory. (This trick is proved to work on this model)
How to do it?
- Get full dd of working phone - it must be phone with the SAME chip and very likely the same model
- flash it to SD-CARD of 32GB or more, class 10 speed or higher, directly to card, not partition
- put card in phone, turn it on and wait
- you should see HBOOT
- select fastboot and flash new FW via it
- viola!
!!!THIS IS COMPLICATED PROCEDURE, I WILL MAKE DETAILED THREAD SOON, BUT FOLLOW IT ONLY IF YOU KNOW WHAT ARE YOU DOING!!!
B) FIREHOSE/SAHARA ATTACK
This could be achieved by sending payload via Firehose programmer that would allow to break verification of SBL or somehow allow SBL to be flashed. Now, PBL blocks attempts to update SBL. I have thesis that it is becouse PBL do not allows for SBL downgrade, so it's version must be higher, but we try to flash same version of SBL so it doesn't work. That thesis needs confirmation.
C) CRAFT BLANKFLASH
This would be last resort. It will work for sure, but this method needs knowledge and I don't know if it is doable.
STEP 1: Get white-listed blankflash checksums from OTA (we would need to reverse engineer those)
STEP 2: Break hash
STEP 3: Craft blankflash with needed hash
STEP 4: Flash
NEVER USE BLANKFLASH (ATTENTION!)
DO NOT try any blankflash files. They can make situation a lot worse and even physically (!) dmage your phone.
D) JTAG
Medusa Box etc.
E) Qualcomm Premium Tool
This can even work, but it is untested and there is a slight chance that can worsen state of phone (needs confirming).
The tool is very advanced and I need to gather info about usage, so very probable to be a good solution if we will learn how to use it!
E) METHOD 7
Interesting method from this guy: (7th option, I have contacted him if it is compatibile)

Hi, same problem. Did you solve it?

Unbrick Honor 9 STF-L09 (NOT FREE, HCU and DC-Phoenix required)

Introduction
THIS METHOD IS NOT FREE. I HAVE NO IDEA HOW TO DO THIS FOR FREE, EXCEPT MAYBE WITH THIS : https://forum.dc-unlocker.com/forum/modems-and-phones/huawei/162196-free-hcu-license-offer
Oh my god. I just come out of 3 days of trying to get this to work, non-stop. I feel the need to write this guide so people in the exact same configuration as me won't have to go through what I did.
Yes there are many tutorials about unbricking your Honor 9, but few are very detailed, and I couldn't make them to work for my european STF-L09. Plus, very few of them have a solution for updating to the very latest version (9.1.0 as the time of writing). So here we go.
The device I did this with, and the situation I was in.
There are so many variants of the Honor 9, and I've tried tutorials that weren't the same model as me, they just wouldn't work.
Honor 9 STF-L09, Europe version, Kirin960.
Previous installed ROM before brick was Oreo (the Pie update I tried to make bricked the phone), but I think you can do that on any previous version.
After the brick, I had a completely dead Honor 9 : no reaction at all, whether I plugged it in or tried any buttons combination.
What you need
- The correct Drivers
- A HCU Client Timed License, which is 19 EUR for 72h, and is going to give you access to the main software we need, DC-Phoenix.
- The correct .dgtks Repair File
- The correct ROM file to flash
- HiSuite
- Tools to open the back of your phone
- A metal object to connect the testpoints (anything will do : tweezers, copper cable, paperclip, sim-tool...)
- Read these two tutorials from www.dc-unlocker.com :
https://www.dc-unlocker.com/dc-phoenix-flash-repair-tutorial
https://www.dc-unlocker.com/flash-bricked-huawei-phones-in-huawei-1-mode
Step 1 - Connect the testpoints
Then open the back of your phone to reveal the testpoints that you can see on the image below (thanks to the user 4r44444 for the picture).
Then, open the Device Manager on Windows, and reveal the COM and LPT Ports (so you can see if you failed at connecting the testpoints or not).
You don't need to connect the two testpoints shown in the picture : you only need to connect the bottom one with anything else that's metal inside the phone.
It will take you some trial and error but eventually, your Device Manager should refresh and show you an unknown device called "SER".
Step 2 - Install the drivers
First, install the latest version of HiSuite to get the basic drivers. Make sure to close it completely (taskbar) and disable the fact that it opens itself when you plug your phone, or it might screw things up.
Then, install the two drivers that are on both dc-unlocker.com tutorials I've linked above.
https://files.dc-unlocker.com/share.html?v=share/984CE114852148B5B9A9CDD918BEC235
https://files.dc-unlocker.com/share.html?v=share/18B15B9D02C945A79B1967234CECB423
The first one "Huawei_Android_phone_drivers.rar" was not useful for me, but the second one, "Huawei drivers testpoint.rar", is to make your COM port recognizable instead of this unknown "SER" in device manager.
In Device Manager, right click on "SER", "Update driver", and locate the extracted folder on your computer.
This is all you need I think, but I installed so many random drivers (which I would not recommend) that I'm not even sure anymore.
Step 3 - Repair the phone with DC-Phoenix
Following "Method 3" from this link, but with some differences : https://www.dc-unlocker.com/dc-phoenix-flash-repair-tutorial
As I said, this method is not free. You can buy credits to make DC-Phoenix work for 72 hours (you need 15 of them for that I think), but since we need HCU, you're better off buying a timed license which gives access to DC-Phoenix.
Open DC-Phoenix, and click on the "Download files" button on top. There, search for the file "STF-Full-Repair-NV-included-Board-A051-7.0.0_r1.dgtks" and download it, it's the Repair File.
https://get-file.org/search#q|STF-Full-Repair-NV-included-Board-A051-7.0.0_r1|1
With your phone connected via testpoints (it has to appear in the Device Manager in the COM Ports, and I recommend changing the COM Port to 1 (right click, Port settings, advanced,...)), go to the "Update OEMINFO" tab, and check "Use BOOTLOADER". There, choose "Kirin960_T2_A7.0_V4" (maybe it's a different one for you, but for me only this one worked).
Then check "Update OEMINFO and unlock Huawei ID", and choose "STF-L09". Click Update, and this should run without errors. If it doesn't recognize your device, that means that it's not turned off and connected via testpoints.
Once that is done, your device may show a sign of life by booting into fastboot mode (or sometimes not). Anyway, you can go directly to the "Update Firmware" tab, and in the "Update file" field, choose the file "STF-Full-Repair-NV-included-Board-A051-7.0.0_r1", check "Rescue Revovery" and "Old slow algo", and click "Update".
After completion, your phone should be able to boot (after a very long press) into a chinese test ROM.
Step 4 - Repair the phone infos with DCU
Follow this tutorial : http://hcu-client.com/huawei-phone-repair-as-empty-board/
Don't forget to change your phone to Manufactured mode (as explained) so you can read your phone info.
In the Step 4, they let you choose between Repair UMTS or CDMA tab, I chose CDMA because I think the phone has a MEID.
Then, when they tell you that you just have to click on "Repair as empty board" to make everything fill in automatically, for me this was complete bs : only my IMEIs were added.
So what you have to do is fill your original SN, WiFi and BT MAC adresses, and so on. But since your phone is bricked and you probably dumped the box that states the SN, you're outta luck like me. It seems like it's illegal to change a MAC or SN number, so I can't recommend it, but I personally just chose random numbers (that have the same number of digits).
For model I entered "STF-L09", for vendor "hw", and for country "eu". Don't check "Erase restricted ver.", since it's only for Qualcomm CPUs. Click on Repair.
Once this is done, your phone should be resetting, and able to boot in the same ROM as before, except in english.
Step 5 - Upgrade to the latest Android 9.1.0
Normally you'd have to do this step with DC-Phoenix : just flash one of their Full Stock Roms they have on their file database (click Download Files on DC-Phoenix, and search for "STF-L09").
You can try that (don't forget that you have to be in fastboot mode (Vol down + plug USB) to install), but it really didn't work for me, and even if it did, I don't know how you'd update after it, because your phone probably won't receive OTAs.
So the solution I found was this one : https://www.reddit.com/r/Huawei/comments/az4bl7/finally_managed_to_update_my_mate10_pro_to_pie/
First, uninstall your latest version of HiSuite to be able to follow this tutorial and install the old version.
Then, the file I chose in Firmware Finder was this one :
STF-L09 9.0.1.175(C432E2R1P5)
STF-L09C432E2R1P5B175 (9.0.1.175)
STF-L09C432E2R1P5T8B175 (9.0.1.175)
I chose the "full" version, which gave me this link :
http://update.dbankcdn.com/TDS/data/files/p3/s15/G3757/g1699/v260353/f1/full/update.zip
After following this tutorial, your phone should boot normally. You can then installs OTAs to update to 9.1.0. I'd recommend resetting the phone after this last step, to have a clean install.
If it doesn't work for you, you can also try this method : https://www.getdroidtips.com/full-guide-install-stock-firmware-huawei-smartphone/
I'll try to answer as many questions as fast as possible (since the Timed License is quite stressful), so feel free to ask !

Does the HCU Client unblock the network after doing the full repair?

Hello , Is this solution still works for honor 9 ?
I can't find stock rom on official website also.

[GUIDE] Restore IMEI number after an NVRAM clear

This thread will go over restoring the IMEI number if you cleared the NVRAM (or fully formatted your phone). The official tool to use is the SN Writer tool from Mediatek but as the P60 processor is not compatible with that, I had to search for alternative ways.
First the legal blerb:
IT IS ILLEGAL TO FLASH A DIFFERENT IMEI NUMBER THAN THE ONE IT CAME WITH (AS FOUND ON THE SIM TRAY OR BOX).
I AM NOT RESPONSIBLE FOR ANY DAMAGE OR LEGAL AFFAIRS CAUSED BY USING THIS GUIDE. IF YOU DO BLAME IT ON ME THEN I WILL LAUGH AT YOU!
Now the guide.
You will need:
- The phone
- A USB cable
- A Windows computer (I used Windows XP, I will get to that later.)
- The drivers linked below (no other drivers seem to work properly or at all.)
- MauiMETA (linked below.)
Part 1: driver installation
These are essential to get the phone to be recognized
- Remove the phone if it's plugged in.
- If using Windows Vista or newer, disable driver signature enforcing (look up online if you don't know how to). For Windows XP there is no such limitation, you can just click a "continue anyway" button.
- Download and extract the drivers (linked below).
- Run "Install Drivers.bat" and follow instructions.
- Reboot the computer to be sure.
Part 2: installing MauiMETA
You will need this tool to start the phone to META mode and write the IMEI numbers.
- Download the setup program.
- Install the software by following on-screen instructions.
Part 3: getting the phone to go into meta mode
- Turn off the phone completely.
- REMOVE THE SIM CARD JUST IN CASE!
- Open the MauiMETA program on your computer.
- Check if the device select is set to "Smartphone" and if the drop-down in the top left is set to "IMEI Download"
- Click "reconnect" and plug in the phone.
- Wait until the phone displays "=> Meta mode" and the application either says "connected" or displays an error box.
Don't be scared of the error box. Just close it. Another may pop up, close that too. If the MauiMETA program displays a few boxes that say something with 6771, it's been detected and the IMEI Download tool is about to open.
Part 4: downloading an IMEI number to the phone
I would again like to warn you that flashing the non-original IMEI is illegal!
If the tool asks if it should find the database itself, click yes. There is no database you can load yourself, so the built-in one will work fine.
- Find your IMEI number(s). They should start with "35".
- Put in the IMEI number to the tool. The middle box is where you start typing. The very last number will need to go in the small box to the right. If you have a dual SIM model, there will be a submenu called "SIM_2" which you can find at the top of the tool.
- Click the "Download to phone" button and it should flash the IMEI numbers.
- When everything is done, hold the power button of the phone for about 10 seconds until it boots into the OS.
If everything went right, you should have a working phone now. I still need to figure out how to restore WiFi and BlueTooth MAC addresses, but the random ones the OS give you should do fine. Also ignore the NVRAM Error 0x10 wifi network, it indicates both are gone. Also some UI bits and pieces might be wrong on the latest Android because for example the notch values were loaded into device-specific partitions.

My device is oneplus nord 2 . When i am using the maui meta software , my phone is always connected on COM6 port and in the maui meta software i can only see COM1 , USB COM and DIAG COM . When i connect the phone the COM6 is displayed and after that when i click on reconnect the maui meta software says please connect cable to target and power on when the phone is already in meta mode. Can you please help me with that ?

Unbricking & Factory
Firmware Restoration Guide​
OVERVIEW:
The 1st Gen Onn Surf 7 is a 7" budget Android tablet manufactured by the Walmart owned electronics brand Onn (styled onn.). It ships with the MediaTek MT8167B chipset, which integrates an energy efficient quad-core Cortex-A35 CPU clocking at 1.3 GHz max, the Imagination PowerVR Rogue GE8300 GPU, paired with 1 GB RAM. The CPU cores are built on the 28 nm process standard. The tablet ships with Android 9 Pie (Go Edition), compiled using the armv7l (32-bit) architecture. The 7" IPS display has a resolution of 1024 x 600 @ 160 dpi (mdpi), and a 17:10 aspect ratio. This device has 16 GB internal storage (12.2 GB useable). The /userdata partition employs the f2fs file system standard, which allows for faster transfer speeds than the traditional ext4 standard. There is also a micro SD card slot for up to 1 TB additional external storage space. The Li-Ion 2100 mAh battery provides around four (4) hours of power at heavy usage, and up to seven (7) hours of juice with light to moderate usage. The main camera shoots images up to 5 MP, while the front selfie cam shoots at 2 MP.
This guide outlines detailed instructions on restoring and/or upgrading the 1st Gen Onn Surf 7 (Model No. 100005206) tablet's stock firmware. This procedure can be used to fix a tablet which is bricked, stuck in a boot loop or is otherwise unable to boot into the Android OS. This guide can likewise be used by device owners who are experiencing issues attributed to firmware corruption, those who simply wish to revert to a full stock and unmodified Android OS, or those who wish to upgrade from an older firmware build. This process will remove any system level mods, root binaries, custom kernels, recoveries, etc., reverting the Android OS and corresponding firmware to an unmodified stock state.
FIRMWARE INFO:
• OS/Version: Android 9 (Go Edition)
• Build No. PPR1.180610.011
• Build Date: September 19, 2020
• Security Patch Level: August 5, 2019
• Build Type: User
• Build Tag: release-keys
• Kernel version: Linux 4.4.146
• Custom Build: alps.mp.p0.mp6-V1.134
• API Level: 28
• Partition Scheme: GPT Legacy
PREREQUISITES: ​
A PC or laptop running on Windows 7/8.1/10/11;​
The SP Flash Tool firmware flashing software (link provided below);​
A factory firmware package for the Onn Surf 7 tablet (link provided below);​
The vCom MediaTek USB drivers installed on your Windows computer (link provided below);​
The factory supplied or a quality equivalent micro USB to USB-A data syncing cable.​
MEDIATEK vCOM USB DRIVERS:
The most common obstacle many members encounter when using the SP Flash Tool is related to device recognition. The SP Flash Tool software flashes firmware directly to the NAND/eMMC whilst the mobile device is in BROM flash mode. In other words, the flash tool is interacting directly with the MediaTek chipset during the flashing process. The user merely needs to connect the powered off mobile device to the PC or laptop using an adequate USB data syncing cable. SP Flash Tool, in turn, will initiate BROM flash mode on the mobile device and commence with the firmware restoration process. In order for your device to be properly recognized in this regard, it is crucial that the MediaTek vCom USB drivers are properly installed and configured on your Windows computer. While I will not be outlining step-by-step instructions here on installing these drivers, I have provided a link in the downloads section below for a comprehensive guide on properly installing and configuring the vCom USB drivers on your Windows machine. Once you have completed this crucial task, you may proceed with this guide. Be sure and thank the OP of that guide, @skeleton1911, if you use his work.
DISCLAIMER
This guide involves flashing the eMMC internal storage device of your tablet with a factory firmware package, thus fully restoring your tablet to its stock factory condition. The procedure outlined below is inherently risky to the overall integrity and operability of your tablet. Failure to follow the instructions properly can, for instance, render your device completely inoperable. By proceeding further, you are assuming sole responsibility for the integrity and operability of your tablet. I have fully tested this procedure on my own device.

Stock Firmware Restoration
And Upgrading Guide ​
OVERVIEW:
The 1st Gen Onn Surf 7 is a 7" budget tablet manufactured by the Walmart owned electronics brand Onn (styled onn.). It ships with the MediaTek MT8167B chipset, which integrates an energy efficient quad-core Cortex-A35 CPU clocking at 1.3 GHz max, the Imagination PowerVR Rogue GE8300 GPU, paired with 1 GB RAM. The processor cores are built on the 28 nm process standard. The tablet ships with Android 9 Pie (Go Edition), compiled using the armv7l (32-bit) architecture. The 7" IPS display has a resolution of 1024 x 600 @ 160 dpi (mdpi), and a 17:10 aspect ratio. This device has 16 GB internal storage (12.2 GB useable). The /userdata partition employs the f2fs file system standard, which allows for faster transfer speeds than the traditional ext4 standard. There is also a micro SD card slot for up to 1 TB additional external storage space. The Li-Ion 2100 mAh battery provides around four (4) hours of power at heavy usage, and up to seven (7) hours of juice with light to moderate usage. The main camera shoots images up to 5 MP, while the front selfie cam shoots at 2 MP.
This guide outlines detailed instructions on restoring and/or upgrading the 1st Gen Onn Surf 7 (Model No. 100005206) tablet's stock firmware. This procedure can be used to fix a tablet which is bricked, stuck in a boot loop or is otherwise unable to boot into the Android OS. This guide can likewise be used by device owners who are experiencing issues attributed to firmware corruption, those who simply wish to revert to a full stock and unmodified Android OS, or those who wish to upgrade from an older firmware build. This process will remove any system level mods, root binaries, custom kernels, recoveries, etc., as well as lock the bootloader if it is in an unlocked state.

The factory supplied or a quality equivalent micro USB to USB-A data syncing cable.​
MEDIATEK vCOM USB DRIVERS:
The most common obstacle many members encounter when using the SP Flash Tool is related to device recognition. The SP Flash Tool software flashes firmware directly to the NAND/eMMC whilst the mobile device is in BROM flash mode. In other words, the flash tool is interacting directly with the MediaTek chipset during the flashing process. The user merely needs to connect the powered off mobile device to the PC or laptop using an adequate USB data syncing cable. SP Flash Tool, in turn, will initiate BROM flash mode on the mobile device and commence with the firmware restoration process. In order for your device to be properly recognized in this regard, it is crucial that the MediaTek vCom USB drivers are properly installed and configured on your Windows computer. While I will not be outlining step-by-step instructions here on installing these drivers, I have provided a link in the downloads section below for a comprehensive guide on properly installing and configuring the vCom USB drivers on your Windows machine. Once you have completed this crucial task, you may proceed with this guide. Be sure and thank the OP of that guide, @skeleton1911, if you use his work.
DISCLAIMER
This guide involves flashing the eMMC internal storage device of your tablet with a factory firmware package, thus fully restoring your tablet to its stock factory condition. The procedure outlined below is inherently risky to the overall integrity and operability of your tablet. Failure to follow the instructions properly can, for instance, render your device completely inoperable. By proceeding further, you are assuming sole responsibility for the integrity and operability of your tablet. I have fully tested this procedure on my own device. Follow the instructions carefully, employ patience, and things should go smoothly. I am not responsible if you brick or otherwise damage your tablet. Moreover, it should be emphasized that this guide is for Model 100005206 (1st Gen) only.

It's from Onn's software support server. This isn't a dump or a homemade package. The firmware is directly from Onn. Where I got it has no relevance to the firmware's origin. Even if I'd got the file at a firmware repo, this would not change anything.
For future reference, if a thread is titled with the term factory firmware, the package originated from the manufacturer. Otherwise, the firmware will be referenced as a partition dump, firmware pull, partition images, or another similar name. The fact that it's called factory firmware infers where the package came from.

Viva La Android said:
Your thread may be titled correctly but not everyone does that. We have looked for Onn firmware for a few years now so I was wondering if you had found a site to download from. If you have it would be nice to share it. If you are getting from OTA then not factory firmware. You could be a little more forthcoming about source, and a little less with the attitude.

Attitude is a good thing. It encourages people to read plain print, comprehend basic grammatical structure, etc As far as source, I share all of my sources. Check any of my dozens of device threads. I always specify the origin, build type, etc. As far as how I obtain factory images, that isn't the least bit relevant to the threads and, quite frankly -- and perhaps a bit attitude coated --it's not any of your business. Indeed, OTA packages and factory firmware images are not the same. You are correct, good sir. Sort of makes my point. That's why one is called OTA while the other is called factory firmware.
By the way, Onn factory firmware is all over the internet in various repos and sources. It isn't elusive by any means.
But yes, if it's called "FACTORY FIRMWARE," guess where it came from? Most members are fairly proficient with literacy and comprehension, so I'm sorry I didn't feel the need to spell that out for the other .48% of the collective member populace. Similarly, whenever I sell baseball cards on eBay, I don't emphasize that the players depicted on those cards actually play baseball. Common sense and the like. Something about the "BASEBALL CARDS" heading perhaps?
Here are a few strikingly similar analogues to emphasize the true wonder of names, headings and titles.
•From where does the Alaskan Husky originate?
•Which galactic star causes a sunburn?
•What makes ice water cold?
•For what weather conditions was a raincoat designed?
•For which food item was pancake syrup originally created?
•When was the War of 1812?

Or, my personal favorite:
What mobile operating system platform has its basis on the Android Open Source Project? Has to be iOS; what do you think? Oh come on, I'm picking on you. Don't take it to heart.
So few files? Allwinner firmware, for instance, is released as a single image -- one .img file. With MediaTek based devices, there is no set amount of individual partition images required to constitute a complete firmware package. This is entirely up to the device manufacturer. Some device makers include all key partitions as well as all sensitive partitions -- essentially, a full partition index for the device. Manufacturers like Hyundai and Motorola are known for releasing robust firmware packages that include the full partition index of images. Other device makers like RCA -- and Onn -- release only the bare minimum of images needed to restore the device to its stock factory state. For this Surf 7 model, Onn has released images for /preloader, /lk1, /lk2, /trustzone1, /trustzone2, /dtbo, /recovery, /boot, /system, /vendor, /userdata, /logo, and /cache. Those images not included in the package are classified either as INVISIBLE or REGIONALBIN; as such, these are simply not needed for restoration purposes and, thus, this is undoubtedly why they were not included in the factory package.
Keep in mind that many images included in typical factory firmware archives are.simply not necessary for firmware restoration; indeed some files are used more for development purposes.
My advice to you, if you don't trust the integrity or legitimacy of a firmware package -- including this one -- don't use it. Get a firmware package elsewhere. I don't post links to channels. Do your own legwork and procure your own contacts with support departments at various manufacturers.

You are right, I guess in my mind I was seeing board software from Huawei. I wasn't thinking about Amazon .bin file or Huawei update.app either. As for legwork it's been a while since I looked hard for Onn firmware. When I first posted how to root the 8" model I was sending email to the company that manufactured the tablet for Onn and searching board serial numbers looking for it. Wow, that's been about 3 years ago now, time flies and things change. That is why I was curious as to where it came from with hopes of finding 8" and 10" firmware. I only had the 7" long enough to root it, post how-to and return it. The other thing I quit searching for was info on MTK's ultraflash, back then it was non-existent. I appreciate the decent reply, thank you.

No problem friend. Perhaps I came across as being abrasive on my replies to your inquiry. I'm sorry if that's the case. Questions like yours are welcome and the ensuing discussion can be informative to other members.
I will give you a good tip on procuring factory firmware: send a professionally worded email to the support department of the device manufacturer. Let them know you need the firmware as a means to restore your own device, as well as for potential custom development projects here at XDA. Most manufacturers know that XDA is the largest custom Android dev community on the planet. As such, they realize that XDA is a great platform for giving exposure to particular devices, which increases overall sales. Anyway, word your email to infer this scenario. Once you get a firmware package for a particular device, make efforts to thank and give credit to the support representative who helped you. Email the representative's supervisor to give positive feedback on the person. Oftentimes, that individual will then freely assist you with future firmware requests, requests for kernel source code, etc. You will progressively gain some valuable contacts among various manufacturers for obtaining factory images.

The factory supplied or a quality equivalent micro USB to USB-A data syncing cable.​
MEDIATEK vCOM USB DRIVERS:
The most common obstacle many members encounter when using the SP Flash Tool is related to device recognition. The SP Flash Tool software flashes firmware directly to the NAND/eMMC whilst the mobile device is in BROM flash mode. In other words, the flash tool is interacting directly with the MediaTek chipset during the flashing process. The user merely needs to connect the powered off mobile device to the PC or laptop using an adequate USB data syncing cable. SP Flash Tool, in turn, will initiate BROM flash mode on the mobile device and commence with the firmware restoration process. In order for your device to be properly recognized in this regard, it is crucial that the MediaTek vCom USB drivers are properly installed and configured on your Windows computer. While I will not be outlining step-by-step instructions here on installing these drivers, I have provided a link in the downloads section below for a comprehensive guide on properly installing and configuring the vCom USB drivers on your Windows machine. Once you have completed this crucial task, you may proceed with this guide. Be sure and thank the OP of that guide, @skeleton1911, if you use his work.
DISCLAIMER
This guide involves flashing the eMMC internal storage device of your tablet with a factory firmware package, thus fully restoring your tablet to its stock factory condition. The procedure outlined below is inherently risky to the overall integrity and operability of your tablet. Failure to follow the instructions properly can, for instance, render your device completely inoperable. By proceeding further, you are assuming sole responsibility for the integrity and operability of your tablet. I have fully tested this procedure on my own device. Follow the instructions carefully, employ patience, and things should go smoothly. I am not responsible if you brick or otherwise damage your tablet. Moreover, it should be emphasized that this guide is for Model 100005206 (1st Gen) only. The factory firmware package for this model is not compatible with newer generation models of the Onn Surf 7 tablet. ​View attachment 5907731​
INSTRUCTIONS
This section presumes that you have properly installed & configured the latest MediaTek vCom USB drivers on your Windows PC or laptop. Again, I have linked a guide for installing these drivers in the downloads section below. Your bootloader does not need to be in an unlocked state. However, this procedure may relock your bootloader if it is presently in an unlocked state.
WARNING: This procedure will erase all saved user data from your device. Before proceeding, make a backup of any files, media or data that you wish to preserve.​
Download the Onn Surf 7 factory firmware package from the link below and extract the contents of the archive to a folder on your computer desktop, or to a folder in another convenient directory;​
Download SP Flash Tool v5.1924 from the link below and extract the archive to your desktop, or to another easily accessible directory;​
Ensure that your tablet is powered off and is not connected to your PC or laptop;. Likewise, ensure that there are no other mobile devices or USB storage devices connected to your computer;​
Open the SP Flash Tool folder that you extracted in Step 2. Click on flash_tool.exe, then right click and choose to Run as Administrator;​
Ensure that the pull-down menu, located near the mid-left region of the interface, is set to Download only. Next, click on the Choose folder icon, located to the right of the Scatter-loading file heading.​
A file explorer will be launched. Navigate to the saved location of the firmware you extracted in the first step. In the firmware directory, select MT8167_Android_scatter.txt, and then click Open;​
The SP Flash Tool will now load the factory firmware package. A violet-colored progress bar near the bottom of the interface will reflect the completion status.​
Once the firmware has been loaded, connect the USB-A end of the data syncing cable to your PC or laptop. Click the Download box located near the upper-left region of the interface;​
Now, connect the micro USB end of the data sync cable to your tablet. If the vCom drivers are properly installed and configured on your PC or laptop, SP Flash Tool will recognize your device and initiate firmware installation via BROM flash mode. A yellow progress bar located near the bottom of the interface will reflect the percentage of completion. Once completed, you will receive a notification that the procedure was successful.​
Disconnect your tablet and use the power key to boot the device. Your Onn Surf 7 should be fully restored to it's stock factory state and running on the most recent firmware build available.​

Hello. I'm not a pro, but I decided to make a tablet firmware (due to the fact that there is not enough memory), I seem to do everything as described here .. but nothing comes out. Please tell me what I'm doing wrong?

I'll research the exact nature of the error you're getting. When you say you made a tablet firmware, what images did you create? I am assuming system.img, & boot.img. is this correct?
You can install firmware images using fastboot mode as well, alleviating any need for SP Flash Tool.

Я изучу точную природу ошибки, которую вы получаете. Когда вы говорите, что делали прошивку для планшета, какие образы вы создавали? Я предполагаю, что system.img и boot.img. это верно?
Вы также можете установить образ прошивки, используя режим быстрой загрузки, что избавит вас от необходимости использовать SP Flash Tool.

Привет! Я использовал прошивку здесь, заводскую. Перед этим установил все необходимые программы и драйвера. Возможно, причина проблемы в том, что я удалил не ту программу, которая написана в описании установки Драйверов. Там написано, что после установки драйверов нужно удалить ''MTK USB Port''. Но к сожалению не могу понять какой удалить. Высылаю скрин, посмотрите пожалуйста, не подскажете какой удалить? Признаюсь, я не очень разбираюсь в этом деле, я даже не "любитель".. Думал, что смогу сделать все по описанию. А прошить решил потому, что памяти под видео, музыку нет вообще, хотя написано, что минимум 12 гигов из 16 должно быть свободно, а у меня только около 1 гига.

Извините, не подскажете, как прошить в режиме Fastboot?

Please post using English. Your previous two posts were composed -- I'm presuming in your native language. I will try to use a translation tool and decipher your posts. The mods here on XDA wil delete any posts or replies which are not in English.

@Kavsokalivit45, I translated your question. Okay, fastboot mode can be used to flash a firmware image file (.img, .fex, .bin, .mbn, etc.) to a specific partition on your mobile device (/boot, recovery, /vendor, /system, /secro, etc.). The following fastboot command reflects that the boot partition is being flashed by a boot.img file.
Code:
fastboot flash boot boot.img
Note that all flashing commands will begin with the word fastboot, followed by the word flash. The next value is represented by the mounting name of the partition to be flashed...in the above example the partition is boot. Lastly, the image filename to be flashed to the partition...in my example, boot.img.
So, if you wanted to flash the /system partition of the Surf 7 tablet, the location of the Android OS itself, you wouid execute:
Code:
fastboot flash system system.img
(This command presumes that the system image has a filename of system.img.)
Fastboot commands can also be used to wipe or format partitions, resize dynamic partitions, set flag values to certain props, unlock & relock your bootloader, along with dozens of other tasks.
While I don't have time to get in depth on this topic, below is a link to a detailed outline on over 2 dozen different fastboot commands and how to use them . https://technastic.com/fastboot-commands-list/
