Downgrade from nougat G model to b10 - ZTE Axon 7 Questions & Answers

Hey guys,
I updated my axon to official nougat, unfortunately I cannot live without my xposed modules so I decided to go back to b10.
I have the bootloader unlocked, but after I flashed nougat my twrp recovery got replaced with the factory one. For some reason I cannot boot the phone into fastboot to flash twrp again so I can revert back to b10.
PS: I tried to downgrade with applying the update.zip b10 package from stock recovery and for some reason it doesnt work.
May I ask you guys what am I missing here to complete the task ? what am I doing wrong ?
Regards

Hi, i had the same problems, this answer helped me:
* Enable USB Debugging
* 'adb reboot edl' (I thing this only applies to european models)
* Put twrp image next to axon7tool and rename it to "recovery.bin"
* Use axon7tool to flash the recovery image: 'axon7tool -w recovery' ( Remember to use zadig if you run into problems communicating with your device )

I have been trying this for the past hour . I tried with qualcomm drivers , i tried zadig but it doesnt work. When i execute the axon7tool command and it doesnt work

I've managed it. Just grab the official software update from ZTE's support website, whack that file on ya SD Card and then go to "System Update" in settings and it should appear there with an "upgrade" button.

I put update.zip on the sd and did what you said but it doesn't appear the upgrade. I tried from recovery mode as well and I get an error about footer

the update.zip (which is provide by OTA) will to work. Try the full firmware from this thread:

Doogee X5 Max Pro Root Recovery OTA

******************Root Recovery Doogee X5 max pro*******************
Your waiting Time IS Now Finished Here is Complete Guide to Root Doogee X5 Max Pro install twrp And More,
Hit :good:
ADB & Fastboot
Before doing most things mentioned below you will need "adb" and "fastboot" installed. Two of your options are to install the Android SDK Tools or the Minimal ADB and Fastboot tool. If you are somewhat new to this I highly recommend the second one. Go here, download the latest version (1.3.1 as of this writing), and install it. When setup is complete you should have an icon for the Minimal ADB and Fastboot tool.
Note: I highly recommend you add "C:\Program Files (x86)\Minimal ADB and Fastboot" to your PATH variable in Windows. This way you can open a Command Prompt anywhere and use adb or fastboot.
1) Unlock Bootloader
Power on the phone and skip through all of the setup options
Go to Settings -> About device
Tap Build number five times to enable Developer options
Go to Settings -> Developer options
Enable OEM unlocking
Enable USB debugging
Plug the phone in to your PC and authorize it
Open a Command Prompt
Type adb reboot-bootloader
The phone should reboot and in a very tiny font at the bottom you should see => FASTBOOT mode
Type fastboot devices to verify that your PC sees it correctly
Type fastboot oem unlock
Press Volume Up to say Yes and wait for this to finish
Type fastboot getvar all and look for (bootloader) unlocked: yes
Type fastboot reboot
You should see your phone reboot a couple times as it erases the phone
Install twrp-
Power on the phone
You can configure your phone now or just skip through all of the setup options and do that later
Go to Settings -> About device
Tap Build number five times to enable Developer options
Go to Settings -> Developer options
Enable OEM unlocking
Enable USB debugging
Plug the phone in to your PC and authorize it
Open a Command Prompt to wherever you extracted the .img file
Type adb reboot-bootloader
The phone should reboot and in a very tiny font at the bottom you should see => FASTBOOT mode
Type fastboot devices to verify that your PC sees it correctly, rename twrp to recovery.img
type fastboot flash recovery recovery.img to flash recovery
Type fastboot reboot
Rooting-
Download BETA-SuperSU.zip and save it to the phone's internal memory or an inserted microSD card
Plug the phone in to your PC
Open a Command Prompt
Type adb reboot recovery
You should now be in twrp. Go to Install zip, find SuperSU.zip, and install it
When it finishes go to Go Back -> Reboot Phone -> No
Once the phone boots up launch SuperSU and configure it as you like
Other Solutions-
i have doogee x5 max-s (i geuss limited editon in algeria ) with mtk6735 . i do evrything and all steps but when i reboot to recovery mode i have ( no command ) in the screen .... how to fix that ? sorry for my ****ty english XD
I had the same Issue but i have found a solution!
After you have flashed the twrp recovery, dont reboot the phone! the "recovery.sh" will replace the twrp on every boot!
Just pull off the battery after flashing, disconnect usb and put the battery back in to the phone.
Now get in to the recovery by pressing volume up and power button together until the select bootmode menue appears.
select recovery with the volume up button and enter with the volume down button.
and now you should be in the twrp main menue.
i hope it works for you too!

It does not work from step 12, all the drives are correctly installed and windows recognizes the cell, the recovery image is in the internal memory and also in the sd but of the error "can not load Recovery.img". I tried all the tutorials on the net to do root and nothing worked.The flash does not recognize to pass the recovery also the installed drivers because windows recognizes the cell phone.

Flash does not pass the file in the download only option, the process does not start. I reinstalled ROM by firmware mode all ok, but the process of passing recovery on command 12 and 13 of the error message. I manually copied the recovery to the sd and internal memory but also from the error. Does not find the file speaks that it is not a command found.

Until today I could not do root on x5 max pro. In the method below even downloading the twrp when starting with the power + volume down button start with a menu in Chinese and if you start with volume up + power goes in the default recovery mode.
Same as Pitro1 I am on 16.01 update and I cannot install twrp no matter what I try.
I tried x32 and x64. I tried rebooting directly on recovery or first load system and then adb reboot recovery. I tried to format all first (now I lost my Imei and so on lol). I downgraded and updated again. Downgrading works only with 26.12 version. All others are giving me Colorado lines on the screen and nothing else...
OEM unlock, file transfer, adb, fastboot, drivers detection, are all working good. Only I cannot install twrp...
Also I cannot write nvram nor with SN Writer 2.1504 nor with Imei & SN Writer 1.7.2, MetaAP mode fails all the time...
I'm just about to send it back...

How old is your phone and what build version was it at before you started? Because this doesn't work on mine. Which of the "Android 6" ROMs did you flash to start with as I've tried flashing mine back to an earlier one in case it's something with the later stuff that my phone has come with but they either don't make a difference or they won't even boot.
I tried the method in the first post here and the phone wouldn't even boot (switch on and you get the Doogee logo in silver for a few seconds then it reboots and does the same again). I had to flash the stock ROM from NeedROM to get it working again.
I've tried flashing TWRPx32 and x64 available NeedROM both with SPFlash tools and with ADB. Generally flashing it with ADB from the command line leaves the phone in that boot-loop. If I flash it with SPFlash when you try to boot into Bootloader afterwards you get the Doogee logo in silver for a few seconds then it seems to reboot again on it's own and boot normally - you don't even get the menu to choose Fastboot, Recovery or Normal. From then on trying to boot to the Bootloader gives you the menu but choosing Recovery gives you the standard recovery.
It's almost as if something is overwriting the recovery partition with the original after I flash TWRP onto it.
Anyone got any suggestions about where I might be going wrong or a way around whatever additional security they might have put in there?
Hi. I have tried to root my x5 max pro with flash tools to load TWRP, but it always restarts normally and the TWRP does not come out. I found you and I started to try this method to load the TWRP. Does everything good, unload bootloader and load recovery, but loading the TWRP gives me error .:
Device unauthorized.
This adb's $ ADB_VENDOR_KEYS is nor set; Try adb kil-server if that seems wrong

rooting X5 Max pro in Ubuntu 16.04
Hi all, this is my first china phone and I basically bought it only to experiment, I'm a linux power user but this is the first time I 'play' with an android OS.
thanks to multiple guides and posts on this and other forums I'm getting somewhere and learning a lot about how to manage an android OS, I'm sharing a bit of info I unovered about doing this under ubuntu but I'm also stuck and in need of guidance, please help me.
Linux specific issues:
I'm running ubuntu 16.04 LTS, installed fastboot and adb tools from ubuntu repos, with these tools and no other modification to my system I could follow the tutorial on how to unlock the OEM bootloader with adb and fastboot.
accordingly to this post about SP flash tool in linux you might need to blacklist a modem manager module in order for SP flash tool to connect to the phone, you also need to install usb development tools (package libusb-dev) and check through dmesg that your linux OS can actually properly read mediatek usb devices.
After following the above mentioned instructions (both the linux sp flash tool tutorial and the bootloader unlocking howto) I could get SP flash tool linux (multiple version) to see the phone after you connect it while SP flash is downloading the new recovery image and flash it with an ok message.
If you get stuck with a BROM error 1013 remember to start sp flash tool with root privileges.
Phone specific issues:
I can get SP flash tool to flash my phone recovery with an ok message confirmation but the phone keeps rebooting with doogee recovery and not twrp. I'm on the newest stock ROM update (20170116) as of current post date. I've been using 32 bit TWRP images from multiple sources and linux version 5.1620 of spflash tool from their website
so my questions are as following:
1) after reading other posts I think I might have to play with different versions of SP flash tool and TWRP until I get the right combination, I think I might be using 64bit spflash tool for linux to flash a 32bit rom or something like that, can anybody confirm precise version number of the stock rom, TWRP and SP flash tool that worked out for you?
2) should I try to install the whole stock ROM posted in this chinadevices thread before trying to flash only TWRP recovery? please also check the linked thread for multiple custom ROM being ported to this phone, please also note that the full stock rom this poster uploaded (it's in the "all firmware" link) contains another flashing tools with chinese instruction called MultiDownloadTool.
www.china-devices.com/forum/index.php?threads/doogee-x5-max-pro-mt6737-custom-roms.20527/
3) I don't have access to a windows installation right now, but I do have a Win10 VM under Vmware workstation 12 pro, so I could try windows version of sp flash tool, do you guys think that USB passthrough would work?

Same here. May a work around would be finding out the oem commands in fastboot. I have seen a tutorial to get them, but you have to be root: https://www.xda-developers.com/how-to-discover-hidden-fastboot-commands/
I search a simple method
Why all so complicate? I am searching for a simple way to root.
For my old Doogee X5, I discovered just
update-ROOT-DOOGEE_X5.zip
Copy the zip to the micro-SD-card
Settings -> Phone info -> Update -> menu "update local" -> choose zip from micro-SD-card.
Start update.
That's all!
Now I search for such a simple solution for my new Doogee X5 MAX pro.
I do not want any methods with "volume down power", because my X5 MAX pro has the menus after "Volume down power" start in Chinese language.

Hi there,
I just tried the first file you posted, (twrp-x32-rom), and this one works for me after all previous attempts to boot up TWRP failed. Thanks for the link !
What I had tried before:
I have a relatively new X5 Max Pro, which I ordered a week ago. I updated the firmware to the newest version (20170116) using the OTA update function.
Then I tried to flash TWRP using the files from "needrom.com" which seem to have worked on older versions of the phone/firmware, but did not work for the newer versions.
I tried 32bit and 64bit TWRP versions and flashed them with SP flash tool, but when pressing Vol+/Power the phone would not boot into TWRP recovery. Insted, when selecting "Recovery" from the boot menu, the phone would show the Doogee logo in silver, then blink once, then boot up normally. When repeating this process, then phone boots into Stock recovery, indicating that the TWRP I flashed was replaced by stock recovery.
However, I just flashed the recovery.img from "TWRP LATEST" (the first file posted by Neaw) with SP flash tools and was finally able to boot into TWRP. I installed the superSU-zip 2.79 included in the link, and I am now rooted. Once again, thanks for posting this :good:

[Brick?] How to solve problem with A2017G (every mode available)

Good evening, guys,
I'm at a loss as to what is happening with my A2017G.
I had TWRP 3.1.0-2, B04 and SuperSU, but the SU wasn't working properly (the message that root privileges were given to my root apps kept popping up but the actual apps didn't work as intended, so to flash the alternative file that I found somewhere in the forums here.
After that, I could not pass the ZTE logo in order to boot the system.
Went back to TWRP, flashed bootstack and stock system by tron again, SuperSU - and the same result.
Without knowing what else to do, I grabbed the full stock B04 file and tried to flash it.
Now, I have a phone whith stock recovery working, without fastboot, with FTM mode, with EDL mode all working, but I can't seem to use one of those in order to restore my phone that, when I try to boot to system, keeps stuck at the screen with the message that the bootloader has been unlocked.
I tried flashing twrp and the update.zip through Mi Flash, but I get a syntax error (my device shows as COM3);
In recovery, when I choose to apply upgrade through SD, a message appears "You can't upgrade from SD card, sorry";
FTM mode works and my phone loads as an adb device (seeing in Axon 7 tool), but if I try to sideload the update.zip through the Windows 10 cmd it crashes with a message saying "bad alloc", or something.
So, I'm at a loss here. I have every modes working, and I still cannot flash anything to my device?
Or am I doing it wrong?
Thank you.
I'm almost sure you can't just flash an official update zip with MiFlash, so do this:
Download this zip, comes from djkuz. It is the full A2017G system with fbop and fastboot
https://mega.nz/#!ZhwR1BAD!PuIWa5Viv...iR-j1U8wZZidTw
After that unpack it and use MiFlash to get it flashed nicely on your device. When you finish, you'll have B10 I think. I experienced random reboots without any thermal problems (even rebooted while it was in my pocket) so you might be better off going to RR but be real careful if/when going back to stock if you decide to do this (i had a DFU brick )

Flashing the extracted B10 package solved it, thanks!
Until now, everything's smooth, running B04.

P9 lite brick? @transition Nougat-MM. PHONE locked, FRP unlock

Hi, second post on the forums, I'm in bigger trouble now.
I unlocked my bootloader and then rooted my VNS-L21 so I could edit my hosts file. I tried going back to official and unrooted firmware afterwards, but something went wrong along the way.
The stages:
-OFW VNS-L21C432B504, obtained bootloader code through DC-unlocker (developer options on, OEM unlock on, debug usb on)
-unlocked bootloader with SRKtool using this method get-instant-huawei-bootloader-unlock-code/
-rooted using Magisk and made a full backup through Revolution Recovery using this method https://ministryofsolutions.com/2018/05/huawei-p9-lite-root-for-nougat-new-method.html
- some tinkering here but don't remember exactly plus I guess it's not that relevant ; I think I got rid of root here
- downgraded from Nougat to MM using dload method according to this thread https://forum.xda-developers.com/hu...torial-rollback-n-to-mm-c432-devices-t3563955 (first flashing rollback package from C432B504 to C900B300, then flashing C432B160 - full)
- everything went fine, bootloader relocked; but I was unable to upgrade to Nougat/B504 - settings-update showed "no updates available", putting update.app in dload folder (obtained from firmware finder, TeamMT, full B504 file) didn't work, pressing three buttons resulted in error (the version not compatible or sth)
-tried dload with previous rollback file
...and now I'm here:
- phone constantly stuck at boot screen (red Huawei logo)
- dload not starting by pressing three buttons
- recovery not starting by pressing volume up
The only thing I can get is white fastboot screen when connected to PC. It says "phone locked" (bootloader) in green, "FRP unlocked" in red. As usb debugging/oem unlock were not enabled this time, platform-tools/adb with command "adb devices" says nothing is connected, similar goes for SRK
Is it hopeless and my phone is thrash or is there anything I can do? Please help!
PS. All I wanted to do with my root was to change hosts file and then unroot/relock phone, seems like it wasn't worth all this work ( https://forum.xda-developers.com/huawei-p9lite/help/retaining-modified-hosts-file-unrooting-t3868641 )
Update: "fastboot devices" in adb directory resulted in detecting my device, next I found and tried command "fastboot oem [PASSWORD]", now there's a change: "This device cannot be trusted" is showing again, in fastboot I see "PHONE Unlocked" in red now. So time to flash some firmware with a command? But which firmware and how exactly to do that?
You have again unlocked your Bootloader? I suggest you flash a Nougat Compatible TWRP and then from within TWRP make wipes. After that use Hurupdater to flash Nougat firmware. First flash TWRP. If it boots into TWRP then format data and then wipe Dalvik/Art Cache, Cache, Data, System and Internal. Next download Hurupdater and stock Nougat Firmware. You need to download three ZIP update.zip, update_data_full_public.zip and regional update file. Next rename them as suggested in Hurupdater thread. Finally place all four files in same folder in SD card and then install and select only Hurupdater.zip to flash. After it complete reboot to stock recovery and factory reset. If all goes well you will be on Nougat.
Thank you so much, HuRU update method was what finally got me from Marshmallow to Nougat
So. I take it your phone is working now? Glad to know and be of help. If you need help with anything then just ask
Yes, it is, I'm currently struggling with systemless hosts on my Magisk rooted Nougat but other than that - everything works fine. Turns out that most of the recoveries I found then were meant for Nougat, only one recovery file worked on Marshmallow (and I've tried quite a few of such files and they were hard to find).
________________
After flashing TWRP recovery, updating Magisk to 17.3 beta and installing newest (4.0.10) version of Adaway - the problem is gone. My guess is that the fault was on Magisk's side as after updating it the "systemless hosts" function in Adaway was no longer grayed out.

Phone doesn't get recognised in Download mode (bootloader)

Hi Guys
So my current goal is to root my galaxy S10+ (SM-G975F) running exynos with android 11. I've seen many methods that are supposed to work for android 11, some more complicated than the others.
The method I chose to stick with, is to enter bootloader through adb using cmd on my computer and to flash twrp that way. (Bootloader is unlocked already)
After that I should be able to install magisk via twrp to complete the root access.
My inital thought was to flash twrp via odin, because odin did recognize my phone after entering bootloader. The problem was that after flashing twrp with odin and performing vol down + power then bixby + vol up + power which normally makes you enter twrp, I got stuck in a bootloop. After that I had to flash the stock ROM via Odin to "repair" my phone.
From what I've read this is due to the vbmeta protection mechanism, that you need to deactivate to avoid bootlooping.
So I heard that you can extract the boot.img file from the official firmware and edit the file with HxD Binary editor to replace a bitcode's value with a series of 0's. Unfortunately I couldn't find that specific code in boot.img.
So the remaining option was to manually flash vbmeta.img and to disable verity verification via cmd.
This is where the big problem lies, my PC does not recognize the device as soon as I enter Download mode. I tried every possible fix I could find online, they all revolve around installing certain drivers and applying them to the device in the device manager. Apparently the device needs to appear in the device manager under "other devices" with a yellow triangle then you can manually select a driver to install. Unfortunately as soon as I enter Download mode (Via cmd command or manually) my device totally disappears from the pc. Only Odin still recognises it somehow.
I installed official android device drivers, specific drivers for bootloader etc.
Every online guide about solving this problem needs you to locate the device and to apply certain drivers to it, but nothing appears for me.
I hope somebody can help me
Format data?
What your twrp version ? your twrp version must be version support 11.
You cant flash Magisk via TWRP. It doesn't work, Install the magisk App
Wrong place to ask this stuff

Problems installing a custom ROM on Grand Prime Duos (SM-G530H)

I have a Grand Prime Duos (SM-G530H), currently running an Android version 4.4.4 and I wanted to install a custom ROM to have a higher version of Android. (Tried installing LineageOS 17.1 from itexpert.120, but any custom ROM with a higher version of Android would do)
Problem 1: No custom recovery seems to work.
I installed the TWRP app and tried to flash 4 different versions of their recovery images (from twrp-3.7.0_9-0-fortuna3g.img to twrp-3.4.0-0-fortuna3g.img) and all of them resulted in a unless glitched gray recovery screen.
I also tried the CWM app but it fails to download a recovery image for the device, tried looking online for a image file but didn't find one either.
In the end I reverted the recovery to the default one that I had backed up.
Problem 2: ADB works but fastboot doesn't.
I downloaded the ADB tools to try and flash the ROM from my computer instead. The ADB commands work, but when the device enters recovery mode the fastboot commands don't work. ("fastboot devices" doesn't even list the device)
Went to check the drivers. Most tutorials say to open the device manager and look for the phone device with an exclamation mark and update the driver with ones downloaded from the official site. To my surprise the device doesn't show up at all in the device manager (not even with an exclamation mark). Trying to install the drivers anyway says it's already installed.
The Odin software showed the same problems, detects the device when it's on, but doesn't detect it when in recovery mode.
Problem 3: Error when installing directly through the recovery mode options.
This probably wouldn't work for technical reason I'm not aware of, but I went and tried anyway. On the default recovery mode there are 2 options, apply update from ADB and apply update from external storage. Tried both, the first using the command "adb sideload <lineage rom file>" and the second using the ROM file in a SD card. Both begin to unpack and install the file but after a while throw an error "E: failed to verify whole-file signature", then the device boots to the usual OS.
So, is there anything else I can try? any other recovery images or hacks that won't give me the glitched recovery that TWRP had? Or another method to install a ROM without fastboot? Maybe using another file format in problem 3?
OBS: the device is rooted and has no "OEM unlock" options in its settings
delete the samsung usb drivers and install an older version. only way you can flash custom recovery is with odin. only way to flash custom rom is with custom recovery. fastboot and sideload wont work, this isnt a nexus
You think the reason why the custom recovery was glitched is because it was flashed through the TWRP app and not Odin? Seems unlikely. Is there any non-TWRP recovery image for my model you can point me to?
