You'd think with all the other posts about problems there'd be something here by now.
Always thank those who are helpful...and just ignore those who aren't.

Mine happened when I wiped Internal storage from twrp. This caused the phone to only see 4gb of internal storage. Came to xda and it was suggested to flash back original boot.img. once that was done 4gb issue was fixed and the radio was gone.
I did indeed try every solution offered (thanks again for all the effort, DrakenFX and others). But, I've come to the conclusion that this is not going to get fixed until XTE releases US images. For other people's sake I hope I am wrong, but I myself decided to proceed with the exchange where I bought it, as I was right at the end of my 14 days (newegg doesn't seem to give the 30 days that xte does). I may be out of an Axon 7 for a while, so for now I am on my amazon ads, Blu R1 HD (with ads defeated

Is there a guide to go back to stock for the A2017G?
i'm on B02 with root and the bootloader still locked.
Like to go back to stock now that ZTE is working on an update to give the A2017G an unlocked bootloader.

Hi all,
I am currently experiencing a bootloop on my Chinese Axon 7. Some of you regulars may have seen me asking in other threads because I've tried to fix it myself, but I've kind of run out of options. Sincerely hoping one of you can help me out!!! I'll buy the winner a beer or 2, haha!
Back story:
Was on B07 with root (tenfar's tool) with locked bootloader and had some issues with the ROM. Like vibrating when I opened the camera and battery drops. So I decided to upgrade to B09. Placed the OTA on SD card and went to: Settings -> update. Worked fine. So I connected it to my PC and made a dump (tenfar's dump tool) of my recovery and boot and stored them. Then I ran the Tenfar's tool, the B09 version and it went like the last one. But when I booted I didn't have wifi, and other issues came up. So I thought: did I make a mistake? So I read it again, checked the COM port again... all checked out. And used Tenfar's tool again. After that it didn't even boot anymore! It plays the nice boot animation and then gets stuck on the end screen with all the pictures.
So after that I restored my dumped recovery.img and boot.img. This is when I knew something was wrong: it still didn't boot! I reset data/cache in the stock recovery: no boot. Still stuck at the end of the boot animation.
What I've tried:
- Flashing the stock B09 update.zip with TWRP.
- Flashing the stock B09 update.zip without updater-script 'assert' and 'get-prop' line. TWRP says 'update.zip is corrupt'. Doesn't install.
- The I put it on SD card and internal memory and tried updating it with stock recovery: 'sorry you cant sdcard upgrade'. That's all it says.
- ADB sideload stock recovery: 'cannot load update.zip'.
I tried different ADB versions, Windows and Mac, different drivers... I tried formatting SD card as FAT32.. Tried different SD card.. Doesn't make a difference.
TWRP log says it can't pass the Zip verification when I try that. If I turn that off it says re.product.name is wrong. But I checked build.prop and updater-script. It's the same! But somehow TWRP comes up with a different one. Also tried removing getprop and assert lines from updater-script. But then it says: ZIP file is corrupt.
TWRP log after trying original, stock B09 flash:
http://pastebin.com/cJivE2TK
Build.prop: moved from /system with TWRP:
http://pastebin.com/b6rryc2n
Build.prop: ro.product.name=P996A03
Updater-script:
Code:
getprop("ro.product.device") == "ailsa_ii" || abort("This package is for \"ailsa_ii\" devices; this is a \"" + getprop("ro.product.device") + "\".");
assert(getprop("ro.product.name") == "P996A03");
But TWRP log: ro.product.name=cm_ailsa_ii
So, yeah, I've been trying on and off for the past couple of days in between work and travelling. Got a back-up phone so it's not that bad. But I really like this phone! It's just been such a pain in the ass the past few days...
I tried researching online and reading all the XDA posts. It is my fault this has happened and feel such a newb for not being able to fix it myself
Many thanks in advance!

Dear All,
ZTE Axon 7 A2017 (Chinese version) Stuck on Bootloader mode.
Device after power on will Stuck on ZTE logo even power button press longer also will Off and came back to square one and the only way to power off is via selection on bootloader page via volume button which consists of Recovery mode, Power Off, Bootloader and some other mode which I can't recall.
History of this issue. Please bear with long story.
Manage to install MM ROM with B13 via sd card installation via update software in phone setting. follow by Unlocked bootloader and Install TWRP 3.1.1.0 then try few different ROM until one day when I use Xiaomi flashtool my PC crash half way through during flashing resulting in device with Pure Chinese ROM and TWRP also got corrupted, when I said corrupted because I install TWRP 3.1.1.0 but when I go to Recovery mode it shows TWRP 3.0 something. with this corrupted TWRP when I try to install ROM it will show loading but end result is NIL meaning same ROM nothing change.
Until this stage I never did a TWRP backup because all this while the ROM is Not my type of ROM from this junction when I boot back to TWRP and I did Advance Wipe most of it except external sd card thinking that I may be able to install fresh TWRP but my Recovery TWRP is residing in phone storage resulting in No more TWRP recovery software. next thing I did was I connect phone to PC and ran adb fastboot tool to detect device and managed to detect device in recovery mode and I make decision to Locked back the bootloader and did just that and Locked bootloader is Succes and it also Erased everything during the process.
To cut short the story after Locked back bootloader only Bootloader mode is accessible and when I connect to PC and enable Recovery mode (Black screen) and EDL mode (Black screen) from Windows PC Device Manager COM port able to see Qualcomm 9008 for this 2 mode.
I must admit after few days of trying to resolve this Stuck Bootloader issue I almost give up.
Then I remember this Woodo magic by jcadduno which recommends XM flashtool version 2016.08.30.0 but unable to flash after trying few version Xiaomi flashtool and the very latest and I mean from Xiaomi Flashtool webpage http://xiaomiflashtool.com/
version 20170425 that break the ice and finally able to load A2017U ROM because this US ROM my phone No Network detected.
From here onwards I unlocked bootloader and install back TWRP (Installation of TWRP via Axon7toolkit) because of Network issue since I got TWRP I install back A2017 ROM but still Not satisfied because Chinese ROM certain Apps having issue because of Google services and I chance upon this Conversion A2017 to A2017U ROM (Hybrid ROM caused ROM is US and Modem from Chinese Modem)
that I'm stay put right now and my phone now is A2017U model.
I hope this experience can help others with similar Stuck bootloader and those who wish to convert A2017 to A2017U ROM.
below is the link that I described Woodo magic.

I am stuck in a position where I can restore my nandroid backups but get Error 7
when trying to reinstall any Rom on a2017u I was able to fix the unlocked bootloop
by the EDL method. The Rom's are the same as the backups. I think I tried to role back to B29 Causing the bootloop) and have had problems ever since.
Should I try flashing A2017Uv1.1.0B32_Bootstack_by_DrakenFX since the Rooms are all B32?
The B15 and B19 Nandroid's still Restore fine.

Hello all,
i don't get onto forums very often but i thought this was a nice one to add to. i've rooted a few motorolas, a few ztes, a cat; i've also bricked those ztes, cat & a few samsungs. i'm dealing with two Axon7U's; one is factory MM-b29, the other is N-b35.
while screwing around with TWRP, i bricked the b35 (the b29 has been bricked for a month at this time) after i had it almost perfected. by perfected i mean a custom recovery & root user access fully acquired. with DrakenFX's {YOURS; thanks so much. i'm learning to get along with linux} extensive files created to save people from themselves i was able to unbrick the b35. albeit its CELLULAR DATA became unhinged; that's something i could've lived with except it was a loaner and had NO CAMERA! it's camera (along with the ability to push both volume buttons at once for say EDL mode...) was damaged having been beaten across a steering wheel several times. so with my newfound unbricking superpowers i decided to take another crack at the b29. managed to get it unbricked but couldn't get it setup with both TWRP & SuperSU without losing one, the other or, both. at times it didn't even boot up. i was doing pretty much everything cited above for reasons 'why'. best way to learn is by trial & error (if one can afford it).
the b29 is rooted right at this moment; i'm working on it as soon as i leave this posting. i used Axon7_EDL_Tool. i used Axon7root. i used MiFlash. i used Fastboot. I used ADB App Controller software too. back & forth i fought for three days mostly due to downloading glitches and i prevailed. i manipulated a stock OTA full system update.zip by happenstance and it Auto_Updated over itself. in other words it already had the same ROM installed. i don't know what it tested to realize it needed to update to what it already had. it didn't have CELLULAR DATA either. just like the b35, it broke somehow while flashing TWRP or SuperSU. funny thing is it still wanted to update that same ROM after it did. while perusing the system update setting(s) i noticed it had downloaded N-b15 and it wanted to update b29 AGAIN! i opted for the Nougat update. it did alright and appears to have fixed it's CELLULAR DATA too. i haven't looked at it since but i'm confident i can gain root user access with a minimal amount of effort.
The main problem i've had with dealing with bricked devices is the age of the file downloads. most of them are simply GONE!, expired links and whatnot. if i'd had a clear path say from a custom recovery and rooted boot image of my factory version or the path that leads to it, i'd have been fixed up long ago. i've found partial 'paths' if you will that almost get me there but no quite all the way. flashing images & zips through fastboot are different from their counterparts entered through TWRP or Emergency Download Mode which of course are both different too. three different ways to get into one's phone makes it almost impossible to keep them perfected.
i'm not sure i did what i'm supposed to regarding this thread. Thank you DrakenFX for your time & knowledge; you've saved my old Axon7!

Hello all update;
b35 Nougat phone is retired. b29 managed to update itself to b35 7.1.1. however, its CELLULAR DATA is still broken. i haven't managed to figure out how or where it's broken so i cannot fix it.
what i'm trying to do now is flash Magisk instead of SuperSU and using a TWRP version 3.0.3-1. heck i've used all of TWRP's versions in my efforts to reacquire CELLULAR DATA.
crazy part is the phone knows its CELLULAR DATA carrier and freely displays all of its hookup info. this is very frustrating.

soft briced p10 lite, Help Please..

Hi
I got my self in quite a pickle here..
so advice or help is very welcomed.
I own a Huawei P10 lite,
with a software version WAS-LX1AC900B049
First off I unlocked the phone, then flashed TWRP recovery, and thus far everything was ok
I wanted to install Lineage 14.1 OS, and I failed because my version of the phone is not supported..
but during attempt installation of Lineage OS , I deleted data, system, dalvik, and cashe..
I did not make a backup!!! (major mistake, I know..)
so effectively I deleted my OS :-/ ..
but it isn’t over jet..
because I could not find a stock rom, namely WAS-LX1AC900B049 version
I thought of debranding my phone to Orange, namely WAS-LX1AC109B110 because stock roms for Orange are available on the net.
so.. using TWRP I replaced oeminfo file..
(this time making a backup of oeminfo)
but once I downloaded Orange stock rom, put it on the
sdcard in /dload folder and entered download mode on the phone, nothing happened, update failed
but.. also changing oeminfo resets the system so I guess that turned off USB debugging..
so now the TWRP is not available because of the system reset, and in the fastboot and rescue mode , adb program from Windows, does not detect device..
so..
it seems I have 3 options..
1. somehow install Orange stock rom
2. make fastboot and rescue mode to work properly so I can reinstall TWRP and go further from there
3. find original stock rom WAS-LX1AC900B049, may be it will work
by the way erecovery does not work, it conects to the wifi, starts serching, and then fails
Help please..

I unbricked the phone
for anyone interested I used adb to unlock the phone in fastboot and rescue mode..
the phone was showing me a message that it was unlocked but it was not
once unlocked previously installed TWRP booted immediately, so from there I installed Lineage 14.1 by HassanMirza01 and it works great

Happy that you fixed your problem but how did adb detected your device as you mentioned it didn't at the first place?
Planning on going back to stock and I think the same trouble would happen for me too.

oH MY GOD!

YOU DID AS EXACTELLY AS ME ...HAHAHAHAHAHAHAH and now im still tryiong to find it solutution ...have you found some?

(SOLVED) I used TWRP and accidentally wrote over the boot recovery partition

Hello,
In a late-night act of utter stupidity, when over-tired, I re-flashed the boot recovery with TWRP and bricked my M3. It obviously can't now enter boot recovery.
I've used TWRP and successfully re-flashed custom roms on my original Mate, and changed regions. (Not in any way an expert, I know how to follow instructions.)
I was trying to convert my Chinese (I was living there) ROM to UK. It's tricky nowadays.
This was a stupid error when tired. Any way back?
I read somewhere that people with the right hardware can do it, but finding someone. I'm in Leeds, UK.
The pad does (did) what I need, and I'm not in a position to buy a new one. If it's dead, it's dead; and I can move on.
Cheers in advance for any input.
SOLVED
See my last post on this thread.
After using Multi Tool V8 to enquire into the machine I switched off and rebooted.
It came back with a "Wipe cache" and "Reset to factory settings" Huawei screen, so I did both and - It booted!
It had spectacularly failed to do anything but boot-loop since coming out of a very dead battery yesterday.
1) Boot recovery, OTA recovery, and dload recovery from SD were all unavailable after the original overwriting of the bootloader.
2) After being dead for months, all recovery options booted from power button plus vol- Vol+ and Vol+/- - but still bootlooping.
Then, suddenly it booted into wipe cache/factory reset screen.
Android 7, EMUI 5.1.3
I have no idea why.
Now fully working. (Including restarting)

I fell in a similar situation after having flashed a magisk module .. unfortunately my nandroid backup didn't restore my devices, but I was able to enter in twrp recovery.. so,..
if you can boot in twrp recovery, not all hopes are lost..
first of all, you must download a stock firmware for your device (i suggest to download trough huawei firmware finder: https://forum.xda-developers.com/tools/general/huawei-firmware-finder-team-mt-t3469146/amp/)
You must download a fullota version of stock firmware
then, you can flash this firmware (3 zip files) trough hurupdater via twrp recovery: https://forum.xda-developers.com/ho...lash-official-firmware-recovery-t3769279/amp/
in order to not overwrite twrp recovery, put the twrp.img file in the same folder and rename it to recovery.img
you can find more info in this topic (follow the instructions, in particular those on how to use hurupdater): https://forum.xda-developers.com/me...ting-btv-dl09-to-unapproved-firmware-t3817541
in order to find a firmware suitable to your device, try to find info on it: you have a mediapad m3 European? American? asian? just wifi or also 4G-LTE (whit a sim and phone functions)? lite or normal version? 10 inches or 8.4?
everyone of these devices have different codenames and suitable firmwares
I found exact firmware for my devices with the procedure described here:
https://forum.xda-developers.com/showpost.php?p=77241673&postcount=3
.. but, if you flashed a wrong firmware, i really don't know if it might help you..
anyway, i wish the info above could help you.

Thanks for the reply, and sorry for the delay. New child has somewhat taken over our lives!
I'll take a look at the tablet again when I have time, probably next month.

Update - Bootloader working after battery drain: Now what?
[Edit] Post redundant as it started working - see OP.

Well...
After being without power for so long I turned the tablet on and it booted!
However, it then went into OTA and updated - rebooted - and locked the damned bootloader.
1) It's showing as rooted.
2) Boot loader is locked.
3) Fastboot & rescue mode comes up.
4) Recovery (OTA) still comes up but "Fails" this time.
I don't recall how I unlocked it last time. I don't ever rememebr an unlock code.
Status:
Fastboot reports it exists.
ADB reports "Null" not found. (ADB drivers installed).
Firmware version: CPN-AL00C233B078
Device name: CPN-AL00
Serial Number: Showing
IMEI: Showing
Bootloader state: LOCK
I have an old TWRP backup - don't know how to use it.
Solutions?
a) Any kind devs prepared to work with me and find the boot unlocker code for this 5-year old tablet?
b) Any other solutions now we know what's what?
I'm self employed without income in this pandemic and can't really afford to buy a new tablet. If I have to, it won't be Huawei.
(There's a T3 10.6" at £89, but I'm not biting - I need to sort out a budget tablet with at least the oomph of the M3.)
Any help much appreciated. :good:

Soft brick on oneplus 6T after version upgrade from Lineage OS

Hi there,
So I unknowingly did something kinda risky and of course, it backfired. I used the in-system update feature of linage OS to upgrade my version on my Oneplus 6T. Can't exactly remember which one the old version was, but it was at least 4 versions older than the newest nightly one. Afterward, the phone got stuck in a boot loop. Also, in recovery, it can't bind/ mount the system, because there is no file directory. "E:Failed to bind mount /mnt/staging/emulated/media/0 to /storage/emulated: No such file or directory." I tried the following:
- went into recovery, factory reset the device, then flashed new clean lineage os [multiple different versions]. Gets back to boot loop afterward. (note that Fastboot shows no bootloader version or baseband version)
- tried unlocking the bootloader via fastboot flashing unlock. It fails with error code: (remote: Unrecognized command flashing unlock)
- tried copying the contents of slot a to b, in case one was severely outdated as the cause for the soft brick as stated in this guide. Didn't change mentioned issue after flashing os.
- installed Qualcomm USB drivers, to get the PC to detect the phone as a USB device
- after that, tried using the ms-downloader tool to reset and re-flash the phone. It does not get detected and the downloader tool waits for the full 15s before returning the error for no detected device.
- tried unlocking the bootloader itself via fastboot flashing unlock_critical. same error as with normal unlock: (remote: Unrecognized command flashing unlock)
Maybe overwriting the possibly corrupt bootloader would be a good bet, but as mentioned, I cannot unlock the device to make the command for that useable.

Hey, so I am not really knowledgeable enough to help fix this, but I did notice one thing: Why are you using the wiki page from Lineage for the OnePlus 6 (enchilada) instead of the 6t (fajita)?

I didn't even notice it was for enchilada, but iirc the file I loaded was only to copy the contents of slot a to slot b. I could search for a fajita version of this. Still, thanks for your reply.

Hi there,
I have the exact same problem. After updating my OP 6T, the cell phone was broken. It's stuck in a reboot loop. Which surprises me, however, because the documentation for this device type recommends that the update be carried out using the system's internal update process. I also noticed that some OTA updates work and some don't. Unfortunately, this is the only way to make use of it very little fun because you never know if the phone is working again when you update. And the security weaknesses show that updates are also important for Lineageos. thanks for the feedback

Hi there,
So I unknowingly did something kinda risky and of course, it backfired. I used the in-system update feature of linage OS to upgrade my version on my Oneplus 6T. Can't exactly remember which one the old version was, but it was at least 4 versions older than the newest nightly one. Afterward, the phone got stuck in a boot loop. Also, in recovery, it can't bind/ mount the system, because there is no file directory. "E:Failed to bind mount /mnt/staging/emulated/media/0 to /storage/emulated: No such file or directory." I tried the following:
- went into recovery, factory reset the device, then flashed new clean lineage os [multiple different versions]. Gets back to boot loop afterward. (note that Fastboot shows no bootloader version or baseband version)
- tried unlocking the bootloader via fastboot flashing unlock. It fails with error code: (remote: Unrecognized command flashing unlock)
- tried copying the contents of slot a to b, in case one was severely outdated as the cause for the soft brick as stated in this guide. Didn't change mentioned issue after flashing os.
- installed Qualcomm USB drivers, to get the PC to detect the phone as a USB device
- after that, tried using the ms-downloader tool to reset and re-flash the phone. It does not get detected and the downloader tool waits for the full 15s before returning the error for no detected device.
- tried unlocking the bootloader itself via fastboot flashing unlock_critical. same error as with normal unlock: (remote: Unrecognized command flashing unlock)
Maybe overwriting the possibly corrupt bootloader would be a good bet, but as mentioned, I cannot unlock the device to make the command for that useable.

Whatever you do in your device,they will not touch critical partition such as bootloader and many more of it, do u still have twrp or other recovery on your device?

I still got the stock recovery. Booting from TWRP image didn't work on my last try, I don't remember the exact specifics anymore. I'll try again.

Tell me the exact problem you with your phone and maybe i can help

once again,
today got informed via updater that a new update is available. I try do install it, but now i stuck again in recovery. And the only think i can do is a factory reset and everything is lost.
can anybody give an info if it is safe to update the 6T trough OTA? It doesn't look like that.

Oof, I thought mine only got bricked because I tried to upgrade across 4 versions. It seems as though even normal updates now cause soft bricks, neat.

I tried again today but there seems to be a connection to the error. I had an update pending, which could be installed without any problems. After the restart, I was informed that there was another update, after installing this update there was a total failure again. Could it be that this is somehow related to slot A / B?

Why don't you try to flash Stock rom on both slots via MSM tool and then just try ota to update to latest build for you specific device

How can i verify if there is an difference between slot a and slot b?
If i flash the stock rom i will be back on oos and that is not what i want i will continue using los, or do we have an idea missmatch there?
thanks for help

What do you exactly want ?

Oneplus 6T recovery bootloop after 11.1.1.1 (rooted)

Dear friends,
I have a recovery bootloop problem with my Op6t European version.
On this week I made an OTA update (11.1.1.1 version) with magisk app. I made with install to inactive slot (after OTA) version.
After this process my phone was reboot and got a recovery bootloop. I have never been in this situation although I made more update with this process.
After that I tried to make wipe cache and reset system settings but it was not succes.
I tried to read forum threads where somebody also has this problem. I found a thread where somebody use fastboot and change slot to use phone temporaly. It's also working for me on but I would like to repair that.
Can I get back my old system with my data? How can I make some solution?
Sorry for my bad english.
UPDATE:
Yesterday I tried to reflash the stock rom with adb sideload , but absolutely does nothing in this case.

I am also having this issue. Can someone point me in the right place for a fix?
