Hi everyone, sorry for a noob problem but I seemed to have soft bricked my phone and was hoping that somebody here would be able to help me out. I have an A2017U in the US.
A short history:
I had been using my phone on B20 rooted/locked with tenfar's tool for about 3 months now, and decided I would try and update it finally before the new year.
To update it, after reading it seemed I would need to unlock the bootloader to keep root on B29 so I decided first step would be to unlock the bootloader and then update to B29. I did the following steps today
1) Unlock bootloader using DrakenFX's guide here http://forum.xda-developers.com/axon-7/how-to/guide-how-to-unlock-bootloader-stay-t3461165 The unlocked proved successful and I was able to boot back into B20 after all the data was wiped, and I followed the instruction to backup the Boot in TWRP. All good.
2) I then decided to follow another of DrakenFX's guides (https://forum.xda-developers.com/showpost.php?p=68873482&postcount=2) to update from B20 to B29. I followed the instructions exactly again, but then the phone just hangs on the ZTE logo on boot infinitely. I wondered if I made a mistake when re-initializing TWRP after unlocking the bootloader. I did a search and found in "Mount" to uncheck "Mount system partition read-only" and unchecked it. The System partition however is unmounted, I'm not sure if that's normal now or not. Even when I check it, after rebooting it goes away. I've checked the MD5 of the ZTE_A2017U.B29_StockSystem_by_DrakenFX.zip file and it's good. I then flashed through fastboot to the new 3.0.3-0 TWRP which I'm now using, and still nothing. It appears I don't have an OS installed. I'm going to guess here the issue is with a setting in TWRP but I've tried everything I could find. Unfortunately I don't seem to have a copy of my stock recovery right now to flash either. I've tried several times to flash ZTE_A2017U.B29_StockSystem_by_DrakenFX.zip and reboot but to no avail. I even tried this tip from rczrazor to delete DATA first and others one by one (https://forum.xda-developers.com/showpost.php?p=69428659&postcount=136) but no such luck for me. Still stuck on the ZTE logo.
tl;dr - I have access to fastboot and TWRP, but apparently no ROM installed even though have flashed now multiple times.
If anybody could help me I would greatly appreciate it. I'm even willing to pay a few bucks in Paypal to help get me going again.
Thank you all in advance.

This happened to me once - boot to TWRP, format data, reboot to TWRP, advanced wipe everything but the external SD card,reboot to TWRP, flash DrakenFX B29 bootstack, reboot to TWRP, flash DrakenFX B29 system.

I have bricked my AXON 7 many times during the last week. The Zip files from DrakenFX are very good. But in case those were still failling...
First, check for corrupted downloads, just check the zip file integrity using 7zip, winRAR or any other tool.
Use TWRP 3.0.3
Try a different ROM such as ZADMix or even CM13.
If everything fails:
Flash TWRP 3.0.2 signed.
Flash the original Stock B29 Boot partition and reboot to recovery
Flash again the verified DrakenFX files.
Ok, hello everyone, I have a quick question. Would the steps for updating to nougat be?: 1) Download and install B29 modded in twrp to reset everything back to stock 2) If fastboot doesn't work flash bl_unlock file from twrp after using axon7tool to flash twrp to get fastboot back? 3) flash back stock recovery and download the update? 4) Install b15 and then go back to edl and install twrp and then flash the unlock again 5) flash modem fix2 to get partitions to work? 6)profit?
so would that work? i am half way through this. i just got back fastboot and was wondering if this would work to help get to B15. I want to see how botched the b15 update is. Feedback would be great for US peeps who did this already to get to b15 and if a better method is there that you used. by all means talk to me like a 5 year old, I am stupid when it comes to brickable chances with modding. And after i do it and get it from you guys help i will write a tutorial and publish on XDA
Hi,
1. If somebody experience this issue with lack of netwrok after Nougat full Rom update, like:
https://forum.xda-developers.com/showpost.php?p=71063185&postcount=121
than follow this fix from another thread:
https://forum.xda-developers.com/showpost.php?p=71054990&postcount=1456
for me it all seems to work fine now.
2. If somebody has issues with MiFlash, I think it is actually better to do the flash within first 5-10, after that it gives strange errors. If so, restrt EDL and press flash on MiFlash a bit faster .
Regards
I failed to boot nougat using these steps:
Boot to edl.
Flashed using miflash full b15 file and then b15 twrp file.
Flashed in twrp a2017 N modem.
Then it gets stuck at 5 secs screen and phone just reboots back to edl. Am i doing it wrong?
However it boots to nougat if only flashing just the b15 full.
Hi,
I had stock B13 Chinese. I MiFlahed fastboot_unlock packge,
did fastboot oem unlock,
MiFlashed B15 twrp,
copied NON-HLOS.bin file from Chinese modem(link above) into extracted B15 Full package folder(which replaced exsiting file in there) ,
reset dalvik etc.from twrp,
flashed B15 full which included already new modem file,
I let it boot finally till the end into standard mode.
This way I don't even have twrp now and all works fine.
Regards

Hi, what you mean you don't have twrp? Is it possible to install it somehow again? Is it possible to install SuperSU then? I'm asking this because I want to install A2017U B15 firmware (with OTA support) on A2017 (Chinese model with B13, stock recovery and locked bootloader) and just want to be sure in everything before I start Many thanks!

Hi,
If you MiFlash B15 Full package it overwrites recovery partition...it is a full package after all. If you want TWRP on your nougat after that you need to Miflsh the B15 TWRP package. However inside the TWRP package, there is also modem driver file which you need to first replace with the new modem file, same as with B15 FULL package.
It is al soooo simple. I had some issues with MiFlash initially, as I read somewhere to "keep the vol up down, power fo 5 sec, release, wait 5seconds and than flash"
However I had near 100% success rate when I did press the flash button around 2-5 seconds after booting into EDL mode. Once you do oem unlock, the process is simple as burning ISO image on a CD
I have it now without that last step. It is unlocked, but without TWRP. I did however MiFlashed TWRP yesterday and it did work fine than as well. I don't however think I need TWRP anymore. I did Dalvik etc. reset during upgrading to Nougat... and that's all I needed it for. Maybe I'm wrong and I will MiFlash it again some day, but honestly, this was first time I flashed any Android phone as I come from Nokia- Windows Phone and all I wanted is working Daydream, Netflix VR for my long business flights. It works now. The rest I might need I will install from play store.
It does have that message about unlocked bootloader when you boot the phone, but it does not bother me and I read somewhere that it is better not to relock he phone.
How do I even know if it's OTA capable? When I checked updates, it says your phone is up to date.
Regards
Ok, now is everything much more clear to me, thank you!
Please help fellow china version users... @RubiCom
I have flashed b15 and the updated modem for china but my signal is still unusable. It keeps restarting the sim and when I go to sim settings, "com.android.phone" crashes. Some other settings related to calls/sim also crashes.
my sim is working fine when I'm on LOS. I really just want to use stock system since audio isn't fully fixed with LOS.
BTW, i'm already BL unlocked since b13. Do I still have to flash b15 twrp? I mean I could just fastboot flash twrp after installing full b15. Is there something special miflashing the b15 twrp package?

I follow all the steps in original thread and after all everything works (at least for me) . But, it was a little bit complicated to make it work
So, first after unlocking I installed B15 TWRP, then entered into TWRP and deleted cache, dalvik, etc.. After that I put my phone into EDL again and flashed B15 original (I didn't boot phone to OS between flashing ROM's at all). But, on boot B15 original I still had some chinese symbols and I couldn't finish setup (phone stuck at google account setup). So, I repeated this three steps (installation of B15 TWRP, wiping everything in TWRP and installation of B15 original) again. This time I've got "android encrypted" or some similar message on boot B15 original(??!!), but after reboot everything was completely normal (except message that bootloader is unlocked, which is normal). I don't have TWRP, but 2G/3G/4G signal is great on both SIM's without lose and I have official updates. Comparing with chinese MM, this Nougat is far more better and faster, like I have a new phone

I figured out what's wrong my my setup but still I can't find a way to fix this.
It seems that when I use my original sim cards (2 sims with the same provider), they both get disconnected every second.
When I put another sim from another provider, it does work but still my original sim doesn't get signal. even when changing slots.
I'm really confused how to make them work together.

That's weird. I'm also using SIM's from same providers, but without any problems.. Don't know what to tell, maybe you can try install B15 TWRP and wipe everything, then install B15 original and try again.. First time I also had some weird problems...

this is actually wierd. I had this problem my my sims. And I had flashed this many times already trying out different methods including miflash and even stock flashable zips from draken. all yields to the same results.
Do you have any idea where to tweak carrier settings from system files? i tried *#*#4636*#*# but still fails.
Unfortunately I don't know it. I guess I had plenty of luck flashing these ROM's, considering how many people have problems..
I have a new (3 day) that updated to b25. Was and is totally stock. Not happy.
Mar was way better on battery and performance. I have downloaded and renamed
b15 factory ota and placed in the sdcard. System update reports a valid update but before I
commit to doing this I wanted to verify with the community that it is safe to do.
After I do this update I am wondering if I can find a factory ota of mar if I can do the same thing again.
Thanks in advance

It's really simple actually: if you install B15 your data will be wiped, after that just skip everything and update to B29 (is B29 the latest? I have a G, dunno) and then use it. What you describe is not the actual performance that it should have, it's your specific case obviously.
I know what you want to do - if you want to remain TOTALLY STOCK I think you are out of options as I don't know anywhere that you can still download the stock ZTE B29 marshmallow. If you are willing to unlock your bootloader and install TWRP then somewhere in here DrakenFX has a B29 rollback that works great - it just won't work with stock recovery

All I really want is to remain stock but rooted and with TWRP for recovery for Nandroid backups. The B25 will not let me unlock the bootloader with Fastboot and when running MiFlash the phone is visible but getting "Hello packet error" I have read another method with fastboot but have not tried it yet (below). Somewhere I read that B25 was the problem and you had to downgrade and the MiFlash method was recommended.
adb reboot bootloader
fastboot devices
fastboot oem unlock
fastboot reboot
I did everything but the first entry.
Thanks for any suggestions.

Go ahead with your rollback to B15 - that will let you unlock and install TWRP. Once you have TWRP go to this thread https://forum.xda-developers.com/axon-7/development/rom-guide-updates-to-stock-files-via-t3469484 and in post #2 you will find A2017UV1.0.0B29_RollBackModded.zip. Flash that, then flash TWRP again (you have to flash TWRP again ONLY if you want to keep TWRP as this flash file will automatically reinstall stock recovery). Also note on B29 I had to use SuperSU 2.65 (not the current one) for root.

By the system update.zip method?
Thanks
Also I would be happy to stay at b15 with TWRP and root.

Wait - you wanted to stay stock? You didn't actually have to unlock if you wanted to. Just by using the update.zip method with some Marshmallow zip you could get to MM, and then you can update to N and you surely won't get the same problems that you've been having...
For example my G is on 7.1.1 and I get 6h+ of battery (right now, 3h36m with 41% left) so your problem is just that your installation was bad. If you unlocked you might as well just do the process that the guy above described though.

OK on the A2017U units you need the official marshmallow B29 package to roll back, and that only works with stock recovery on a clean B15 N install. The Rollback package I told you to use earlier will roll you back to B29 marshmallow NO MATTER WHAT YOU ARE USING (I have used this a lot, and OBVIOUSLY there are differences between the the A2017U version in North America and the A2017G version in Europe). If you want stock and rooted, I personally recommend B29 marshmallow over B15 Nougat, but either way go for it (I think the marshmallow had a much better radio than any of the Nougat packages). If you are interested in TWRP and root, I found B29 marshmallow much easier for both, and the marshmallow version of android also gives you Xposed, but back to your first post, you mentioned wanting marshmallow, and this is the best way to get it.
Step by Step method
1. Roll back to B15. Use the update.zip method. It will factory reset your device so backup everything you can't lose
2. Use MiFlash to unlock and install TWRP - check that thread on XDA for instructions.
3. (If desired) In TWRP, install the B29 marshmallow rollback. Do not reboot into system afterwards.
4. (If step 3 is done) In TWRP, flash TWRP. The marshmallow rollback will overwrite recovery with stock recovery
If you do this you will have exactly what you wanted in your original post. I can personally tell you this works, as I have tried every custom rom on here and always wind up back at B29 marshmallow when all is said and done. It has never failed me, and it will never fail you either.
Dear Seniors.
I am facing great hardship because my phone is stuck at boot logo.
No booting in recovery mode to flash another rom.
I did unlock bootloader of it by using tuliptool with success. After that i flashed custom rom in it. after reboot it is happening that.
Please suggest to recover it.
Did you flash twrp after unlocking? Did you make backup of stock ROM? Perhaps find a version of the factory firmware and flash that.
Dear I have no backup and i flashed TWRP recovery.......
It is to aware you that i did relock bootloader now my phone is working properly. but i am unable to enter recovery mode. !!!
Now my phone is running android 6.0.1 B02
But i am failed to root this rom uptill now due above mentioned problem.

I found software update notification but when i update an error accruing while update. (This update not compatible with this device"
In easy words......... my recovery.img has been corrupted. I have no idea to get rid of this situation.
I planned to unlock my Mini's bootloader this weekend. After reading this post, I decided to act later until the root cause has been figured out.

Several people myself included have been able to use tuliptool to successfully unlock and root the device.
mine is hard bricked too. but I think it is worse than the case listed on the op.
if you want to hard bricked these are the steps:
follow the procedure to install the Spanish ROM 6.1, than another android m b12, than finally the android seven......use tulip tool and install twpr fine, root ect. amazing ROM.......buuuuut......I lost my IMEI somewhere in this process, and the original FTM which had a small menu changes to another static one, without the menu.
I needed this menu to open the com port to fix the IMEI. than I had the brilliant idea to re-flash android M via twrp (without modifying the zip file to remove the recovery, something I knew so well from the older axon mini).
results:
-lost twpr because the stock ROM wrote over it,
-cannot boot the OS because I flashed android m but the phone had the aboot 7.
-i now have a brick
I need a genious to sujest something to bring it back to life........sh....t...sh...t.....sh...t
any chances I could inject aboot7 via ADB through my dead recovery which somehow the phone recognises? ADB shell still seems to be working
thanks
