[ZTE Axon 7 Questions & Answers] AnonVendetta:
I have an A2017U. Earlier I EDL flashed [MENTION=5672995]jcadduono[/MENTION]'s B19. But now, when I use VolUp+Power, it goes to stock recovery and reboots. So I can't factory reset the phone. And I don't have TWRP either. I also can't boot into the stock ROM by just holding power, stock recovery appears for a second and then the phone turns off. When I hold VolUp+VolDown+Power I get a black screen and a solid red light, which is supposed to be EDL. But MiFlash doesn't detect the phone.

What the hell am I supposed to do to recover, when I'm locked out of all the modes I can use to get out of this mess?!

Thanks!
[ZTE Axon 7 Questions & Answers] lafester:
Always replace recovery with twrp when flashing. If you can get to test mode - vol down + power - you can adb reboot edl.
[ZTE Axon 7 Questions & Answers] AnonVendetta:
[MENTION=421262]lafester[/MENTION]: Do you mean the FTM screen? Is that test mode? I've seen it before but I've always thought it was 100% useless. I've never heard of anyone flashing from that screen. What about DFU? When I press VolDown+Power the stock recovery screen just flashes for a second and the phone shuts off. Same thing when I press VolUp+Power. I simply don't see how flashing a stock EDL can brick the phone, MiFlash reported it was successful. No errors at all. But now, I can't get back into EDL. Just a solid red light and a black screen. MiFlash wont read it, neither will Axon7Tool. I think the issue is that my data and cache partitions are F2FS, stock recovery can't read them, so it just shuts down. I had this issue before, but eventually the ROM booted and told me to factory reset. So I did and all was dandy. No luck this time around.
[ZTE Axon 7 Questions & Answers] AnonVendetta:
Another thing I've noticed, is that when I reboot to EDL, I get a black screen and a solid red light. I was previously running AEX Oreo, I have heard that the Oreo bootstacks can screw with EDL. Before Oreo I got a black screen and a red light that blinked once and turned off, then I was able to EDL flash. I have read that if I let the phone fully discharge (by allowing the red light to drain the battery completely), then maybe I can try something else in a few hours once that is done. But what? really need some help here.

Thanks!
[ZTE Axon 7 Questions & Answers] bornlivedie:
I run Oreo bootstacks and EDL works fine.

If you cant enter recovery or EDL mode, you will have to try with a deep flash cable (very low chances of it working) or follow this guide https://xdaforums.com/axon-7/how-to/guide-dfu-unbrick-guide-disassembly-t3731152
[ZTE Axon 7 Questions & Answers] lafester:
So did you try it? Yes, ftm screen is test mode. You also need to tell us what device manager is saying when you are in edl mode.
[ZTE Axon 7 Questions & Answers] bornlivedie:
he has a black screen with a red light, that's DFU

EDL only blinks a red light once

thats a 4th category brick

crap, i overlooked that. Maybe [MENTION=3836686]kitcostantino[/MENTION] knows more? Honestly I never understood what was his problem or what he did to fix it, but it was on an U and it looked exactly like DFU...
[ZTE Axon 7 Questions & Answers] lafester:
Only time I ever had a dfu issue was with the very first Chinese beta. I was able to get into test mode and then boot into edl.
[ZTE Axon 7 Questions & Answers] AnonVendetta:
So, no access to FTM, otherwise my issue would be solved and I wouldn't be posting. I let the battery drain all day by letting the red light burn through it, I had figured that letting the battery drain would be the equivalent of short circuiting the pin that [MENTION=7799420]Choose an username...[/MENTION] speaks of. No power in the circuits=reset. I got it to where the red light either does blink, or stays on for a moment and turns off. But EDL and other tools doesnt recognize the phone either way. I read some of the 4th category brick guide, it says you need to disassemble the phone. But I am no good with hardware, if I take it apart then it will very likely not go back together in one piece. So I would like to avoid that. I also don't have the money to pay a technician, I prefer to fix my own problems. I bought my A7 new from NewEgg, it came with SquareTrade insurance. Maybe I should call ZTE and try to get a warranty repair? I can just tell them I was repairing via EDL from a bootloop, when it all went bad. Don't need (and probably shouldn't) mention TWRP, etc.

I have 3 QUSB__BULK entries under "Universal Serial Bus Devices" in Device Management. Normally, it would show up in "Ports" category, if EDL was working properly.

[ZTE Axon 7 Questions & Answers] troy5890:
If you still have your warranty, then I'd send it back to ZTE if you can't get it to come back to life.
[ZTE Axon 7 Questions & Answers] AnonVendetta:
[MENTION=247600]try[/MENTION]5890: I still have the standard warranty, as well as SquareTrade insurance. But if there is a way out of this that doesnt involve hardware disassembly (which might make things worse), then I'd rather go that route instead. It's Sunday anyway, so I'll have to wait til tomorrow to call either ZTE or SquareTrade. If there is a chance of resolving it before then.....
[ZTE Axon 7 Questions & Answers] Choose an username...:
You have another problem there. Right click on the QUSB_BULK and Uninstall device. If you were on DFU it would show up as ZTE Handset Diagnostic Interface.

If you ever used Zadig then that's your problem. If not, it's worth trying anyways
[ZTE Axon 7 Questions & Answers] kitcostantino:
just to clarify, what i have had success with,is letting the phone completely die, then charging with my laptop (which is lower power than a QC or standard plug) until i get the 'connect charger' message. at that point i charge using my Quick Charge oem brick and cable. after that, for whatever reason, EDL works for me again. Prior to that, point, DFU mode was all i could get. no recovery, no fastboot, no EDL. Just solid red light after holding the EDL mode key combo (vol +, vol -, power). but no Qualcomm 9008 whatever it is, ive done this a couple of times. its always trying to go stock, but something had failed.

while it makes no sense to me, id say its worth a shot. boot into what you have at that point, which is only DFU mode, and simply let the phone die. if it powers off, power back on, and let it die completely. then plug up to a computer usb port, let it charge until you get that message, and after you charge above 30-40% min, EDL to something else. i must also say somewhere in my mis-adventures, i killed the imei on not one but two a2017u boards, so something does not like going back to MM. at that point, i had a bad download of b15 that was breaking touch functionality, so i flashed back to MM. The board flashed fine, but serial and imei went bye bye.

[posted for the greater good...this was a pm. ;) ]

Dude, it may seem daunting, but this is one of the easiest phones to disassemble i have owned. grab some guitar pics, a magnet (for screws), and something like the top to the axon 7 box, and a relatively high quality phillips precision screw driver. the trickiest parts are the speaker grills, the fingerprint cable, and separating the back. the screws beneath the tape/speaker screen material i just didnt put back in my axon phone that has been taken apart. if ya have warranty, ya may as well send it in. i presently have not one but two boards that are without an IMEI. i keep my second axon in an easy to disassemble state as i didnt put the screws that are under the adhesive and speaker grills. i can board swap it in about two minutes now as ive done it like 20 times. it really isnt bad man. watch jerryrigeverything's video and its a piece of cake.

however, if you want to use warranty and not have to pay ($79) to ZTE to use Passport warranty, dont take it apart. if ya take it apart and fail, worst case scenario, ZTE will charge ya $80.

Square Warranty i know nothing about.

critical step on drain/trickle charge/edl is to just let it charge by itself on the oem usb cable to the computer until you get the 'plug in....' screen. just going over it in my mind trying to be certain i mentioned everything i did. in both instances, i was on stock.
[ZTE Axon 7 Questions & Answers] Oki:
No need to open your device, just follow this guide.
[ZTE Axon 7 Questions & Answers] AnonVendetta:
Just a status update, I've spent the last 2 week's trting to undo this brick, always stuck in DFU. I followed [MENTION=3836686]kitcostantino[/MENTION]''s advice to the letter, but I can never get to EDL. I'm beginning to think I'll have to mail it in for a warranty repair, I'm flat out of ideas to try, short of disassembling the phone.

I did also contact [MENTION=3044858]DrakenFX[/MENTION], I noticed he posted a link to an EDL/deep flash cable on Amazon, he said it worked for him several times. I sent him a PM to get clarification on whether the battery needs to be removed before using the cable, but he never gave a direct answer on that, even though I asked twice.
[ZTE Axon 7 Questions & Answers] Oki:
No need to remove the battery or open the unit. It is importatn to get the EDL cable from a reliable source. I provide 2 links in the guide I recommended to you in my last post. You can also try the DIY solution. It is easy.
[ZTE Axon 7 Questions & Answers] DrakenFX:
as [MENTION=319057]Oki[/MENTION] mentioned there is NO neede to open the device/ remove battery or anything internal to use use the EDL Cable....

by the way , i did mention on one of the PM that there is no need to open the device neither remove battery to get the cable to work...
[ZTE Axon 7 Questions & Answers] AnonVendetta:
I just got the deep flash cable that [MENTION=3044858]DrakenFX[/MENTION] recommended on Amazon. It shipped in from Hong Kong and took an excruciating 3 weeks to arrive. After fiddling around with it for several hours tonight and getting nowhere, it does not work, period. I followed the seller's instructions to the letter (except I didn't remove the battery). Do not buy, it is a complete waste of money. Nothing happens when I plug the cable into the phone and then into my laptop, phone is completely powered off. A red light doesn't even show up in the top left corner. Windows 10 doesn't acknowledge that the phone is plugged in. And holding down the button on the cable does nothing either. I held it for anywhere ranging from 8 seconds to over a minute. If I try to enter EDL mode with VolUp+VolDown+Power, it just goes into DFU mode with a solid red light, same as before. Link to cable is below:

https://www.amazon.com/gp/product/B06XXCLMGM/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

I will fiddle around with it a bit more tomorrow, but if I can't get it to work then I will return to seller for refund. I have already rated it as 1 out of 5 stars (since Amazon wouldn't let me give 0, which is what they deserve).

[MENTION=3044858]DrakenFX[/MENTION]: Can you give exact down to the letter instructions on how you used the cable? Maybe I'm just not doing something right, but I doubt that is the case.

Thanks!
[ZTE Axon 7 Questions & Answers] le011:
Only opening the device works

Hi all

i had the same problem whit the phone,

nothing workd not even the edl cable.

So, i opened the device and short the check point and ,walla, edl mode and flashing rom whit miflash.

Its not so hard,dont waist more time .

Good luck.
[ZTE Axon 7 Questions & Answers] Victor13f:
I've also tried my luck with an EDL cable with sadly no results. As soon as I plug the cable in the phone starts. I've tried following instructions from here but with also no luck. Guess RMA attempt it is.
[ZTE Axon 7 Questions & Answers] AnonVendetta:
After screwing around with the cable some more, it's a no go. I won't be returning it for a refund because it will cost more to ship it back to Hong Kong than what I paid. Maybe it will prove useful in the future, since it's essentially a splitter with a USB 2.0 on one end and USB C/MicroUSB on the other end, making it useful for flashing most types of Android phones.

I believe my Axon is stuck in some kind of low power idle mode, when I plug it in to PC or AC adapter it will charge for a few minutes on a "battery too low" screen, then the screen goes black and never turns back on no matter how many times I unplug/replug it. So I can't even say for certain how much percent the battery is charged. I have even tried plugging it in all night with it still on a black screen. If I plug it into my laptop, and it has a minimal degree of power, Windows 10 will acknowledge it but it still remains stuck in DFU. Pressing the button on the EDL cable as instructed makes Windows give the familiar "USB device plugged in" sound, but still DFU only. MiFlash reported that flashing the B19 EDL was successful, but there must be some sort of damage to the firmware that is too deep for the average user to fix.

I don't plan to open the phone because I still have warranty and insurance, and I'm no good at disassembly. I also dont have the proper tools. If I take it apart then it may not go back together properly, then warranty is shot too, ZTE will know it has been messed with. My reasoning is that this could happen again later even if I fixed it myself by short-circuiting the test point, so I would rather do the proper thing and let ZTE assess and fix the situation. This might also reveal any other issues going on behind the scenes, which I might not find alone.

I contacted ZTE via phone yesterday, after a 20 minute wait I spoke to a helpful woman who seemed to be knowledgable enough. We spent an hour going through different scenarios. And then it was concluded that sending it in would be the only way to fix. Next I just have to fill out the form that was emailed, then I contact the insurance company to see if there are any special instructions that should be followed. Afterwards I just have to call ZTE again before mailing. This is what I should have been doing the first day this happened, if I hadn't waited then it might be fixed by now. But I prefer to try to fix my own problems first.

When it returns I'll make a final post.

Bootloop logcat: https://pastebin.com/HYyT39x6

After installing magisk on LG-v496 it enters bootloop.

I have installed TWRP from here https://xdaforums.com/lg-g-pad-83/help/tmobile-gpad-f-8-0-v496-info-t3139894

The problem is, that the touch input doesn't work in TWRP. Also USB OTG mouse does not work in it (altho it is claimed that it does on the thread). I have confirmed the same OTG + mouse setup works on another phone, so it must be the tablet.

I am able to use the adb commands during bootloop, but that is about it. Any ideas how to get the mouse input in TWRP or solve it with adb?

flashed the stock kdz in download mode. all good

Hello !

I've a question for those who have the Zenfone 5Z 6GB RAM !

I get it since 3 days, but battery life isn't so good ! The first time i've had 5h02 SOT and yesterday 4H49 ! When i see review ou forum people can reach more than 7h SOT ! I'm surfing normaly, don't abuse of snapchat and use "auto brigtness" .

I just update today the new version "WW_80.11.37.79" i'll see if the battery goes better with this update ..

And sometime battery decrease from 2% in 1 second...

And an other question, today i've charge my phone but i see than the phone is charging fast ! I'm using the orginal charger from Asus.

The charger have Quick Charge ? And there is a way to disable this ? Fast charge kill the battery :(
[Asus Zenfone 5Z  Questions & Answers] DogeLordTR:
Am I that person who gets +7h? :laugh:

Yes, that charger is a fast charger. 18W so it's really fast. You can use QC3.0 chargers with this phone. Btw I've never heard that fast charging kills the battery, where'd you read it? I'm just asking. But using phone while charging kills the battery.

I couldn't find a setting to turn off qc.

About battery drain: did you play games? If yes, battery drain is normal but if not maybe they solve it with updates

Note: One + means you are using qc2.0, two + means that you're using qc3.0

I'm using stock charger for the moment ! And yes you are maybe the only one who get 7h i can't reach more than 4 SOT .. So :( worse than my S7E :mad:

Hi ! For me facebook isn't in the app list of app who consume battery life, the first is screen and after others app are between 1-2% .. Not bad ! Hope that my battery isn't defective ..

[Asus Zenfone 5Z  Questions & Answers] Spiklearn:
Bro I am facing the exact same issue!! Even I was wondering that if I got a defective battery.

Initially on the first 2 days I wasn't even able to reach 4Hr SoT mark. But after update it seems to have "improved" a bit I'd say but not by a largr extent. Now I manage to get just about 4.5 to 5 Hours of SoT.

I still find it strange that how all the reviewers are able to get 6-7 hours of SoT even with their "heavy" usage for the review purposes and I am struggling to cross 5 hrs with just about moderate usage.

*Note- I use 2 sims and data (volte) is turned on most of the time on one sim, throughout the day. I also keep my location on and keep the brightness at auto settings.

If anyone else is facing the same issue and/or has a solution for this Please let us know!!

Thank you! Appreciate it!!
[Asus Zenfone 5Z  Questions & Answers] papp0us:
There is no way you can take 7+ hours SOT from Zenfone 5Z. With my Zenfone 5, i always get 5-5:10 hours SoT, IF i'm not listening to radio or Spotify too much. On a normal day, with data, sync, bt and stuff always enabled, i get 5 hours. One day that i was using it all day for youtube and netflix i almost got 6 hours, but never more than that.

I'm not complaining of course, 5 hours SoT out of a 3300mAh battery is good enough for me, but you'll propably never see 7 hours.

Battery backup problem

My phone also gives low poor battery backup and also when in night my phone is in idle in 12am to 7 am and battery drain 7% to 10% is it for all device.??? And phone also in power saving mode please help me.
[Asus Zenfone 5Z  Questions & Answers] Spiklearn:
Like I said I was having the same issue. I was getting just about 4 Hrs of Screen-On time with very light usage, to the point that I thought that it was me who got a defective product and got in touch with the e-commerce seller (Flipkart from India) from which I made the purchase about getting it replaced. Following which the Technical support team told me to do the following..... Factory reset the phone. Then when you start up again, DO NOT back up the settings from previous phone, instead do SET UP AS NEW DEVICE. Then when you are done setting it up, you need to update all your pre-installed applications to the latest versions and also make sure that you have the latest system update running. Then you need to restart your device one last time before installing any other applications and continue with your regular usage.

I followed these steps and implemented them day before yesterday and it did actually improve my battery life from hardly 4 Hrs of Screen-On to exactly 7 Hours before my phone died (100-0) with my mixed slightly heavy usage with 4g data/wifi always on along with gaming, music streaming to speakers and a good amount of YouTube too.

Try the above stuff maybe it will solve your problem.

Hope this helps!! Peace :)

I have my schedule set to 10.30 pm -6 am but the phone still charges to a hundred within its usual time(an hour or so if i plug it in at 11pm). How exactly is it supposed to work?Does it just hold it at 100 then for the rest of the night? Just wanted some clarification if its even doing anything at all
[Asus Zenfone 5Z  Questions & Answers] Pratik.barca:
For me night time drain is 4-5%. The duration is ~ 7 hours. Regarding battery backup I can confirm it will increase with time. Small advice is that dont let the battery fall below 40%. And dont charge south of 90%. I follow these steps.. I easily get 6 hours screen time with good 18-25% remaining. I use GPS in high accuracy. I have no complaints regarding battery.

Edit - if you have bought it new, then for the purpose of calibration you can drain it to 0 and charge it till 100 once. For me this worked. On the second day I did this and after that battery backup increased.

How and what is your formula on getting the 8hrs SOT? Can you please enlighten me on what is the magic behind it? I never really hit 5hrs SOT..

I use phone on Power saving mode (not super saving) You will not find any big difference in performance between normal and Power saving, I also Keep the phone on Auto Brightness . Since i got the phone i never used AI charging just for the info if it makes any difference .

Also I'm confident if i don't play PUBG or any other game daily, Phone can easiy go 9-10hrs even when it stays connected to Wifi all day .

Also I never charge my phone during night cause I've faced battery draining issues with my old android phones by doing that often (or even too many ) times .
