[MENTION=4126377]tdm[/MENTION] mmm at the end the link I've provided with ZTE flash tools is generic Qualcomm flash tool. As far as I can see this will not detect phones in adb sideload.

One thing I still don't understand, why the US version of the full ota start to transfer with ADB sideload? thi image is also > 2GB....

also I've found this website: https://sites.google.com/site/zteopenfirmware/download-mode

do you think can help in some way?
[ZTE Axon 7 Mini Guides, News, & Discussion] lchichiarelli:
[MENTION=4126377]tdm[/MENTION]

some little steps further...

the US full ota is smaller than 2GB that why it's working at the beginning.

I've found that inside the zip there is a file called build.prop, in that file there is a line:

ro.product.name=P852A12

I changed it in ro.product.name=P852A11 and saved the zip.

Now adb sideload fails at 47% with error:

E: failed to verify whole-file signature" "E: signature verification failed" "E:error: 21" "installation aborted."

I think is something related with the crc of the zip file that is changed after I've edited and saved it.

There is some way to edit the build.prop file w/out to touch the CRC ?

Thanks
[ZTE Axon 7 Mini Guides, News, & Discussion] tdm:
Yes, the US full OTA is under 2gb which is why it loads and then fails at the model assert.

The assert that is failing is actually in the edify script (META-INF/com/google/android/updater-script). But you cannot change it without invalidating the digital signature.

Stock recovery verifies the digital signature of all packages before allowing them to be flashed. The key that is used for the signature is secret. The vendor creates a new secret key for each device.

Thus, you cannot change the recovery zip to avoid the assert. Sorry. :(

at this point I think I'm screwed and I will not be able to recover my device anymore. I've downloaded all the EU versions of B2017G but also the oldest (V1.0.0B02) are > 2GB.

ZTE customer service told me they can reflash it back to the US rom but they charge for it 79,99$, the crazy thing is that I've sent the phone to them and paid 79,99 last month for a cracked camera.

I'm wondering how they are able to flash it back to US rom.... perhaps do you know some engineer at ZTE that can send me a special recovery file????
[ZTE Axon 7 Mini Guides, News, & Discussion] tdm:
Ouch, that's a lot. You can almost buy a new device for that.

What they will likely do is take it apart and force EDL mode, then do a full factory software restore.

To force EDL, you expose the mother board. There are 6 test pads (little copper circles). You take a metal piece like a paperclip and connect/short two of them while plugging the device into a PC.

If you want to try that, I can put you in touch with someone who already did it on his axon7mini.

Device remains locked and fastboot mode is disabled

KEYWORDS: axon 7 mini, unlock, bootloader, file axon_mini_unlock.zip, B2017G_USAV1.2.0B14, Android 7.1.1, update from ADB, device remains locked, fastboot mode disabled

Hi to everybody. Hi [MENTION=4126377]tdm[/MENTION]. I am new here and I have a ZTE Axon 7 Mini.

I tried to unlock the bootloader with the file "axon_mini_unlock.zip" but I couldn't. My phone current version is ZTE B2017G_USAV1.2.0B14 / Android 7.1.1.

I am going to describe the proccess I followed:

Entered recovery mode. Recovery info: ZTE/P852A12/tulip, 7.1.1/NMF26v/20170830.223936, Supported API: 3.

Tried to apply update from SD card but I got the following message: "Sorry, you can't sdcard upgrade" (In another attempt I activated "OEM unlock" and the error message changed to another one).

Tried to apply update from ADB; it succeeded with the use of the command "adb sideload axon_mini_unlock.zip". Some messages: script succeeded: result was [1.000000]; Succesfully verified integrity of /system for MDTP; Install from ADB complete.

Entered to bootloader but "FASTBOOT MODE" and "DEVICE STATE - locked" are in red color.

Finally, In Developer Options I found an option named "OEM unlock" so I activated it but the bootloader screen information remained the same.

I repeated the process again after activating "OEM unlock", applied update from ADB with a successful result but the device remains locked and fastboot mode is disabled.

As a final comment, but unrelated with the final result (because I updated from ADB), with "OEM unlock" activated the error message from "Apply update from SD card" changes to "E:failed to mount /sdcard (No such file or directory)", "-- Couldn't mount /sdcard", "Installation aborted" (previously it was "Sorry, you can't sdcard upgrade").

Thanks in advance for the possible help.

[ZTE Axon 7 Mini Guides, News, & Discussion] tdm:
Please read the OP. The boot loader is not locked from the factory on any known models. I have no idea what the unlocked aboot is reading/checking, but whatever it is, it's not the actual boot loader lock flag.

The only reason to use the unlock aboot is if you really want to use fastboot. It's otherwise less functional and more annoying than the stock aboot. I don't recommend installing it, and I don't use it myself.
[ZTE Axon 7 Mini Guides, News, & Discussion] LeonardoGC:
Thanks tdm.

I'll investigate a little more.

I want to install the TWRP custom recovery (and then flash the LineageOS ROM) so I'll follow the method explained in this thread:

https://xdaforums.com/axon-7-mini/development/unlock-tuliptool-unlock-twrp-custom-boot-t3682781

(considering that is not necessary to use Tuliptool to unlock the Axon 7 mini, because it is already unlocked).

One final concern: I installed the unlock aboot ("axon_mini_unlock.zip" via update from adb), my question is: do I need to restore the stock aboot?, if the answer is yes, how could I restore it?

Thanks in advance.

Regards
[ZTE Axon 7 Mini Guides, News, & Discussion] tdm:
You do not need the unlock aboot. All you need is to flash TWRP using tuliptool. From there, you can do whatever you wish with your phone.

You can find the stock aboot in the boot stack zip.
[ZTE Axon 7 Mini Guides, News, & Discussion] LeonardoGC:
Thanks tdm.

I am familiar with TWRP, so once I get it flashed it should be known territory.

Which pins

Hi there,

I bricked my new phone trying to install linageOS. Now its stuck in a bootloop and none of the key combinations work... :( My last hope is the EDL force method. Which pins are the correct ones to force into EDL-mode?

thx in advance

Lt. Tuvok
[ZTE Axon 7 Mini Guides, News, & Discussion] tdm:
Use this guide:

http://en.miui.com/thread-310325-1-1.html

Except note you do not have to pull the wire while the cable is plugged. You can unplug, remove the wire, and plug in again. The device will stay in EDL mode without being plugged in.
[ZTE Axon 7 Mini Guides, News, & Discussion] Lt. Tuvok:
Hey, great stuff! :good: :)

That way i where able to install TWRP again. But sadly, it shows no partitions or storages at all. So every try installing a ROM is ending with "unable to find partition for path '/sytem'" , path '/data' , and so on. And always shows: Error creating fstab

Anything I can do?

Edit:

I finally got LinageOS running! :D I don't really know why it worked now, but just in case it may help someone: I reflashed the original recovery via tuliptool, entered the EDL Mode via the "USB cable trick" and flashed TWRP once again. After rebooting to TWRP no more errors accured and everythig worked like a charm!

A big THANKS to tdm for developing the tools and providing all the needed image files and informations!

SUPPORT with recovery and root

Hi,

I'm looking for some support, is too complex for me to understand all the possible way for the different firmware versions for the different hardwares... I give up... I feel for somebody could be so mechanically easy that I hope to meet that connection :)

I own a ZTE Axon 7 mini,

credo US version

B2017GV1.2.0B14

V.Kernel 3.10.84

7.1.1

I recently tried the axon_mini_unlock.zip tool but it says is for 7.1.1 version...

should I downgrade? how in my condition?

Or what to do?

I would like to install the recovery to root and then remix rom or a 8.0 version when available

No way to root without losing the data eh? :)

Thanks a lot, I really appreciate the help!

P.S.

I'm also not able to take a proper backup of the partitions from this condition, I just made a disk to disk copy of the files...(at least)...
[ZTE Axon 7 Mini Guides, News, & Discussion] LeonardoGC:
Hi alekbom.

You don't need to use the axon_mini_unlock.zip file to unlock the the bootloader. The bootloader is not locked from factory.

In "Developer options" (in Settings) you need to activate an option named "OEM Unlock".

After that you need to flash TWRP (the recovery) using tuliptool.

You don't need to lose your app data. Before installing your desired ROM you can try installing Magisk in order to gain root and do a full backup with "Titanium Backup" (requires root). If you need to backup your contacts, sms, calls logs you should try "Super Backup" (doesn´t require root).

Then you can install the ROM of your choice.

Regards

PS: After flashing TWRP you can make a proper backup of the partitions.

---------- Post added at 07:00 PM ---------- Previous post was at 06:32 PM ----------

The bootloader is not locked form factory. In "Developer options" (in Settings) you need to activate an option named "OEM Unlock".

I understand that you need to update to Android 7.1 in order to use tuliptool to flash TWRP (recovery).

locked

"After some testing, it appears that the Axon 7 Mini is not locked in any way. In other words, apparently neither this package nor tuliptool's unlock are required to flash custom ROMs. The only apparent advantage to flashing this is to get access to fastboot, which provides a way to flash a custom boot and recovery (among other things)."

My axon 7 mini is still locked. I can't take a screenshot of it, but the bootloader is locked.

Where did you find TWRP for the axon 7 mini?
[ZTE Axon 7 Mini Guides, News, & Discussion] koktey14:
I think European versions locked but us version is unlocked.
[ZTE Axon 7 Mini Guides, News, & Discussion] hakkafusion:
Did you ever find a solution? Here's my situation: (US version P852A12)

1. Flashed axon_mini_unlock.zip

2. Device boots, saids "Device software can't be checked for corruption." (I assume this is verity)

3. fastboot oem unlocked

So I now have bootloader unlocked, fastboot flash recovery tulip-twrp-7.1-3.2.3-r2.img or r1 OKAY and finishes, but cannot boot into recovery.

fastboot flash boot tulip-us-7.1.1-b12-boot-noverity.img also OKAY, but neither b12 or b14 allows it to boot. (Still stuck on 5 secs bootloop)

fastboot boot tulip-twrp-7.1-3.2.3-r2.img FAILED (Too many links)

Cannot boot into EDL.

Been at it for past 4 hours, probably read everything on these forums that's related.

fastboot rom b13_fastboot.zip will not flash through fastboot because size is too big.

Any idea why twrp refuses to boot?

Edit:

So for those interested, I got TWRP installed and flashed Lineage. Here's what I did:

Followed instructions from tdm (post #51)

Warning: Do not reboot until all flashes are done/stated otherwise.

1. Unzip B2017G-US-v1.2.0-b14-bootstack.zip to a folder with fastboot& adb

fastboot flash ddr ddr.mbn (this will fail, but here for completeness)

fastboot flash dsp adspso.bin

fastboot flash splash splash.img

fastboot flash rpm rpm.mbn

fastboot flash modem NON-HLOS.bin

fastboot flash tz tz.mbn

fastboot flash hyp hyp.mbn

fastboot flash sbl1 sbl1.mbn

fastboot flash aboot emmc_appsboot.mbn

fastboot flash keymaster keymaster.mbn

fastboot flash cmnlib cmnlib.mbn

2. After the above, you should be on b14 firmware

Now:

fastboot flash recovery tulip-twrp-7.1-3.2.3-r2.img

fastboot flash boot tulip-us-7.1.1-b14-boot-noverity.img

If either recovery or boot flash fails, reflash aboot emmc.appsboot.mbn from axon_mini_unlock.zip so you are not SOL and atleast still have fastboot. (I did not personally test this because my flashes worked).

3. Reboot, boot into TWRP. Then I sideloaded lineage-14.1-20181225-nightly & gapps. I got an "adb: failed to read command: No error" @47%(lineage) & 55%(gapps) on the host side on both flashes, that's fine.

Before you reboot, do a factory reset followed by advance > wipe data; (to remove any passwords even if there is none).

Reboot into Lineage, gratz, you now have TWRP & Lineage 14.1 installed.

Lesson learnt:

a.) OTA to b14 before flashing axon_mini_unlock.zip or twrp

b.) fastboot flash recovery TWRP does not work on b12, only b14

Hopefully this saves you the 8 hours of headache that it caused me. I originally thought my device was on b14 but apparently not.

How to unlock bootloader for Snapdragon617 ? (China Mobile CMDC : A2 (M636T))
[General Questions and Answers] tiago0289:
First of alli beg your pardon for my English.

I have a Xperia Z5 (E6683) about 6 months ago and everything worked normally until I upgrade to Android 7.1.1.

My cell phone does not recognize that it is plugged into the charger or the PC.

- Restore factory settings.

- Reinstalled Android.

- Installed Android 6.0, 6.0.1 and 7.0.

- PC Companion

When I finish installing any version of Android, the USB connection of the cell phone works normally. I can recharge, transfer files ... After 1 or 2 days the USB simply stops working or if I reboot the phone the USB also stops.

I tried Android 5.1.1 and the usb works to load, but not to transfer files. If I restart the smartphone connected to the pc it recognizes that it is connected, but I can not recharge.

Apparently it's not a physical flaw, it seems more of a logical thing, since it works normally when I finish installing Android. It seems that some internal Android process causes the defect to appear.

I've been researching for almost a month, but I do not think anything like it, has anyone ever seen this kind of defect? Would anyone know how I can solve or indicate some place where I can search for a solution?

Thank you.
