Hello everyone, I'm using the A2017G and recently the Camera's started acting up and I tried to clear the cache but it still doesn't work.

Tried to restore to an older nandroid and something went wrong, ended up doing a factory reset. Now I'm on a fresh version of B03.

Booted into recovery and it is still TWRP, but rootchecker from playstore says root access is not properly installed.

I rooted it using the command line method back in mid 2016 following DrakenFX's guide, and my bootloader is NOT unlocked.

I intend to get back root access and update to B10 while I'm at it, what is the best course of action? Do I follow OP's guide and run through everything again?

Appreciate any help, thanks in advance!

Hello,

First of all, a big thank you for this guide, it is really helpful.

I was just wondering, as the guide was posted some time ago, if links were still up to date ?

I have another question for the A)24 point : in this guide, it's said that this operation (so swiping to 'Allow system modification') is not needed, as it "can actually brick things..." : is it still true ; is it safer not to "swipe to Allow system modification" ?

Finally, at step A)6, it is said to download TWRP.img and .bin ; but the .bin ("twrp_rec_tenfar.bin") is not used then in the process. Is it normal ?

Thanks for answering,

Nussbi11

I install twrp when my axon 7 running with nougat (my mistake) Now my phone doesn't open. Stuck loading menu (only ZTE text). How can solve this problem?

Hi!

I'm facing "error 7" and have already tried different versions of TWRK and ROM.

Anyone an idea?

Battery not charging anymore

So i did everything as said here. The only difference was, that i tried to flash a custom kernel in the first round. Also i flashed crdroid instead of LOS. I freshly installed everything cause my TWRP jumped back to the 3.0N one. Also in System Info it shows me now, that i have a A2017U instead of A2017G which i thought i had (for real..). So now my Phone stays on 27% and doesnt move up or down. When I looked up with ampere i just got a maximum of 80mA.. how do i fix this battery problem? :(

Edit: Had to format my PC, just plugged in my phone and unlocking the bootloader works. Didn't install any drivers, no Zadig just plugged my phone to my PC and waited for Windows to recognise the device.
[ZTE Axon 7 Guides, News, & Discussion] Dead Short:
Hey guys, got something for everyone struggling with doing the procedure (installing TWRP) on a Win10 PC:

1. Download Zadig from wherever.

2. Run the zadig.exe.

3. Disconect your PC from the internet (easy workarround for that annoying auto-driver-updates) and open the windows device manager. Plugin your device, you don't need to unplug it during this proceedure.

4. Use the command "adb reboot edl" to get your android device into edl mode, just as discribed in the guide. You device should show up as an unknown device/with an yellow exclamation mark, except for the case the wrong drivers are already installed. If so, uninstall the device and also tick "uninstall drivers", when the dialog window shows up.

5. When the drivers are uninstalled, hold all three buttons (power, vol. up and vol. down) of your device until the device manager flashes/refreshs. If this wasn't already the case, it now should show up with an yellow exclamation mark as an unknown device. It should now also be detected by Zadig.

6. Now install the driver Zadig offers automaticly, just click the button and you're good to go. After success, you can reconect your PC to the internet. It should not install the wrong drivers again.

7. That's it! You can now continue to follow the instructions starting from point 16) on.

Sorry if there was some bad english :)

untrue, I think this method works on Nougat, but regardless, it's not the only way. You can use bkores's axon7toolkit and it should do everything automatically

You don't get Fastboot automagically by downgrading to B10 by the way

Hello,

is there a answer to this questions?

Is it correct to follow A)24 (allowing system changes in twrp before unlocking the bootloader)?

Thanks for helping
[ZTE Axon 7 Guides, News, & Discussion] dantedakilla:
I'm having trouble with my phone, at the moment. I was following the guide and got all the way to step 16 but it failed giving me a what() error. So I thought I'd just stop and give up until I noticed the fix for it in your post. I followed the instructions on that and now my computer only ever reads my phone as 'ADB Interface'.

I've tried replacing drivers with Zadig, uninstalling the driver then re-plugging in my phone. I even restarted both my com and phone including factory resetting it, but my com still reads the device as 'ADB Interface'. I can't even get past "adb devices" anymore.

-EDIT-

Never mind. I fixed it. I set the USB connection type to 'PC Software'. So far so good. Progressing nicely.

-EDIT 2-

I'm stuck in the 'unlocking bootloader' phase. My computer doesn't seem to detect my phone in bootloader mode. I type 'fastboot devices' to check if it's being detected but I get no result. Continuing with 'fastboot oem unlock' just gives me a (waiting for any device) prompt but doesn't do anything else. I don't get any sort of instructions on my phone either.

Hi!

I have a A2107G and unlocked it, coming from B04.

Everything worked so far, but I have messed around with bootstack/modem and now I am struggling.

I flashed a new ROM with TWRP (different versions) and the ROM (doesn't matter which one) is stuck in booting animation.

What can I do to bring it back to life?

Also another question: After switching on, directly after the ZTE logo coming up, a black sceen with some infos coming up and stay there for 5 secs.

Is there a way to get rid of this
[ZTE Axon 7 Guides, News, & Discussion] mark1003:
It could be a problem with encryption.

I think you have to format data in twrp (wipe>format data) to get rid of encryption..

Then you can flash your ROM.

---------- Post added at 05:40 PM ---------- Previous post was at 05:38 PM ----------

Can your describe the steps you have done to install twrp?
[ZTE Axon 7 Guides, News, & Discussion] Sui77:
Hi Mark,

honestley not.

I have done it according to the guide and anything was fine afterwards.

I think I ****ed it up by trying to make the system partition write/read

Will try to flash the original system image this evening and start over from scratch.

Damn, i have also a NEXUS 6p and stuff is so much easier on that device, but i need dual sim :(
[ZTE Axon 7 Guides, News, & Discussion] mark1003:
Thank you for the hints (universal bootloader, ...). It helps to finish the installation of lineageOS.

But now i have a problem with encryption.

During the system reboot the encryption seems to be active and i am asked to type in a password, although i have installed no-verity-opt-encrypt-5.1

and formated data to get rid of encryption before installing the new ROM.

So my LineageOS can't boot.

A hint would bee very helpful :o
[ZTE Axon 7 Guides, News, & Discussion] Choose an username...:
Dunno, formatting data is the only way I can think of. like, use the button to format data, not just wipe. It formats the internal storage too though
[ZTE Axon 7 Guides, News, & Discussion] mark1003:
Please report, if you find a way.

Meanwhile i have the same situation. Can't boot:

"Your software device can't be checked for corruption ..."

I have tried a lot: formated data, install no-verity-opt-encrypt-5.1.zip,

changed format of data partition to ext4 (because format data changes it to f2fs every time)

Nothing helped.

---------- Post added at 07:25 AM ---------- Previous post was at 07:18 AM ----------

That is what i have done. See my post before.

format data seems to format data and (hopefully to remove encryption).

Installing Lineage and booting leeds to an error message during boot because

the device can't be ckecked for corruption.:eek:

Maybe it is another problem? Not encryption??
[ZTE Axon 7 Guides, News, & Discussion] Choose an username...:
That is not an error. "Your device can't be checked for corruption" is the 5 second screen... how much time did you leave it there?

Either you have another problem that leaves the phone jammed there, or you're not waiting enough (other people didn't wait too)
[ZTE Axon 7 Guides, News, & Discussion] mark1003:
Of course i waited. More than once. But then after a few seconds i always was forced to type in a password for the encrypted phone

before lineage could start finally. This was very confusing, since i thought i have removed encryption.

Well, i tried again and again, rebooted to twrp, installed the no verity zip, formated data and so on.

And now finally the system started without asking for a password. The message "Your device can't be checked for corruption"

is still displayed, confusing but not a problem (i hope so).

If you ask me why it is finally successful, i don't know. I have repeated the same things again and again.

All Samsung Phones and Tablets i rooted the last years were very easy to install with cyanogenmod and lineage

compared with the Axon7.

You need to flash universal bootstack
[ZTE Axon 7 Guides, News, & Discussion] Choose an username...:
After flashing universal bootloader also install TWRP_3.1.1-0.img (have it prepared somewhere) then your ROM of choice. If you don't, your TWRP will get downgraded to a really craptastic version after rebooting to it
[ZTE Axon 7 Guides, News, & Discussion] Predatorhaze:
Thanks for the reply.I found out it has to do with the bootstack,i got the universal flashed.But! yeah there is a but,i think because i missed a step.When i boot into TWRP it keeps asking for security patern because it decrypt my internal sd card.Even when i wipe everything it keeps asking for the unlock patern when i enter TWRP,i know the patern,i can unlock it but i dont know why i need to do this everytime?Also when i flashed a clean rom install,when the device boots its also asking for this unlock patern,when i swiped my patern the phone boots again to android...What is happening here? This isnt right.Its booting and working but everytime i get this patern security!

Is it a option to reinstall TWRP?or something else?

EDIT: I have read TWRP can ask for a password,you can press cancel and swipe the bar that says something with the modifications...yes it works.But when i boot my phone (when i see the bootanimation for 10seconds) it still asks for this password,when i set the password it continue with booting (again i see the bootanimation). Is this normal due some security?I dont think so,but im asking what i did wrong and how i can solve this.Clean install a rom or/and full wipe does not solve this

[ZTE Axon 7 Guides, News, & Discussion] Choose an username...:
Lol noes. First of all, this guide was designed for MM, so it will work in B11. Second, the phone has to be in EDL mode! Not turned on with MTP or whatever, but in EDL mode. Have you even read the guide? You need to put it in EDL, install the Zadig driver, THEN use axon7tool.

Don't take this lightly! You can brick it in a way that only a full disassembly will fix. Read everything before attempting to do anything

Or you could use axon7toolkit, but i think it may fail

So guys, tell me what I'm doing wrong.

I have a A2017G which I just got yesterday. It had MM 6.0.1 installed.

I was able to flash TWRP, but only the 'old' one twrp_rec_tenfar.img. All newer ones seemed to get flashed successfully but all I got was a black screen when I boot to recovery.

Unlocking of bootloader failed when I tried to dd the fbop_lock.img file.

--> Permission denied.

Well, every guide says if that occurs I should do it while in TWRP.

Problem is, while in TWRP there is no adb device available at all.

Out of frustration I reflashed the original recovery and did the upgrade to stock Nougat, B09 I think.

Where did I go wrong?

Hello everybody, I'm new on XDA,

I read your guide, every word and every santence and I also read DO NOT use this guide on stock nougat, but I'm a fool I forget I should have downgrade first, but I already made mistake, I managed to flash TWRP and swipe to allow modification and cannot reboot into System.

I can only boot into TWRP 3.0.2-2 and EDL mode and FTM, but in Device Manager my A2017G listed as A2017U with yellow exclamation mark and when I access EDL Model it listed as QUSB-BULK

I can access micro SD by enabling MTP from TWRP, and I can send data to that micro SD, can I flash stock firmware using TWRP and unbrick my device?

I think the bootloader still locked

can anybody here help me? I just bought this phone....

is there any way to save my phone?
[ZTE Axon 7 Guides, News, & Discussion] Choose an username...:
yes there are a bunch. Let's start with stock recovery for now.

Download the latest stock recovery image from the download center, also download an official update package from there (Nougat B09 for example. Not the TWRP flashable ones), put them on the SD card, install - install image - install the image to Recovery partition. Then Reboot - Recovery.

Now that you're on the stock recovery, install from sd card - select the system zip that you got - install

If this fails tell me and I'll tell you how to use MiFlash.
