[Xiaomi Mi CC9 / Mi 9 Lite Questions & Answers] MFSZ:
I checked it and got the result "anti: 1".

Reading this topic, I thought anti = 1 is a result that allow me to downgrade to miui 10. Is that right?
[Xiaomi Mi CC9 / Mi 9 Lite Questions & Answers] mogamycool:
if you want to downgrade you have to unlock the bootloader then use fastboot of miui 10 to install that version or use recovery version with twrp recovery. But it's a failure attempt to downgrade while your device is locked.
[Xiaomi Mi CC9 / Mi 9 Lite Questions & Answers] obiwanbartek:
I you want to downgrade to an OFFICIAL rom designed for your version of phone (EEA, Global, China etc), locked bootloader shouldn't be a problem. Am I mistaken?
[AT&T Samsung Galaxy S 5] Zed Leppelin:
Pardon me if this is a stupid question! Every Android data recovery app that my ATT Samsung S5 encounters cannot recover deleted data without root. And as seems to be very clear around here, rooting this thing can't be done. How the heck do I do this?

Hi, [MENTION=2247733]ante0[/MENTION] , [MENTION=2642882]Pretoriano80[/MENTION] and everyone else!

Been lurking on these forums ever since mate 10 Pro was released, but due to being one of the folks to downgrade from emui 9 to brick I had to take my phone to service for board swapping as I wasn't in a situation to do the testpoint fix myself.

Now, I'm looking to get the bootloader unlock code again and to my surprise even the 3rd party sites are down.

There's a guy at minstryofsolutions that offers bootloader unlock code using testpoint but he asks for 40$ + access to pc for 2 hours + refuses to describe in any way what he's doing to the device and why will the device end up rebranded + new imei and with it new bootloader code ( Obviously device in that condition can't be taken into a Huawei service center) .

So, upon searching and trying to find if anyone had found a way to unlock using testpoint I stumbled upon this : https://xdaforums.com/mediapad-m5/how-to/downgrade-unbrick-huawei-device-methods-t3915693

Op and several others seem successful with downgrading their devices and using dc unlocker to get the code once the security patch is no more.

Op even mentions that for kirin 970 it's probably the same process but I haven't seen anyone sharing their experience doing the same on 979 devices.

Couple users are having issues as well and while op was quite helpful he and several others that were helping out seem to have been gone missing. There's a guy helping out with issues regarding this process but it seems rather finicky when even after doing all this and flashing with dload certain parts like lte modem remain present on a WiFi only tablet.

Does anyone have passes for easy firmware or dc unlocker firmware database? Is anyone willing to give these a try and see if the process will work on our devices or if it will ask for verification of some kind for images being flashed?

It looks quite promising, so if anyone has a bricked device ( Maybe someone that was refused at the Huawei repair center during the wave of downgrades ) would you be willing to give it a try?

I've got no tools, no passes and no other device to use while playing with this.

Obviously, I'm not asking for you guys to go out of your way and brick the device so I can know whether this is a viable option or not lol. :cowboy:

Just thought about sharing and seeing if anyone more knowledgeable has anythiny they'd like to add to this as a tip or personal experience trying this method.

This might be what we are looking for when it comes to unlocking device / downgrading to lower versions.

Hopefully the post I linked helps someone, in case anyone has experience with this please share as well!

Anyways thanks in advance!
[Huawei Mate 10  Questions & Answers] ante0:
You can as I've done it.

Use testpoint (this will void warranty as you have to remove back of the phone) and flash bootloader files from DC Phoenix, there are several Kirin970 to choose from but only one should work. DC will tell you when phone is in fastboot mode after flashing.

Then I used IDT (Image Download Tool) to flash board firmware. Boot to board firmware and used HCU to repair imeis and all that. Then used HCU to get an unlock code. After this flash dload firmware back to Oreo (needs to be a new dload because of updated bootloader).

HCU fix guide for BLA:

1)Flash oeminfo (own backup) from fastboot OR dump existing oeminfo using adb pull (adb pull /dev/block/bootdevice/by-name/oeminfo) then flash it from fastboot.

2)Backup modemnvm_system, modemnvm_factory and modemnvm_backup using adb pull from a command prompt (/dev/block/bootdevice/by-name/modemnvm_system and so on)

3)Flash backed up modemnvm_system, modemnvm_factory and modemnvm_backup from fastboot

3)Modify and brand with HCU in the CDMA tab (check everything but those that erase/flash empty board) (remember to fill vendor and cust)

4)Unlock sim 'Direct SIM Unlock'

5)Read Bootloader code if you ever used HCU to get code before or if you need unlock code

6)Download and flash Oreo service firmware from androidhost.ru using a OTG cable and a memory stick. Pick the latest Oreo one you find for your cust

If you fail to do any of the steps above you will end up with no IMEIs or 'No Network' and/or Sim lock

So you'd need: DC/HCU pass and unencrypted board firmware (gem-flash and easy-firmware has them but they're paid.).

I have not tested using DCs own board firmware.
[Huawei Mate 10  Questions & Answers] Rstment ^m^:
Thanks a lot!

Will any of this process leave bootloader unlocked / relocked along the way?

I'm experiencing screen burn in due to outdated firmware and was gonna get the code, apply new adhesive I buy online and have them replace the device's screen + seal it properly in the process so the water resistance remains - kinda essential to hide any signs of tampering like bootloader unlock '-' ( 2nd burn in on Oreo firmware now, both happened within few months of the device running old firmw )

Thanks for the guide as well!

I'm not completely sure how to do the whole process yet but I'll try getting all the software I can right now and try figuring it out.

One question tho, do you have any screenshots you can share of which firmware will work out of those several that you mentioned and is there any possibility of brick by flashing wrong xload, etc.?

I'm on 8.0.0.156 c432 and was gonna drop to 142 or 143 - will have to check which one is the latest without security patch.

Glad to know this is a possibility! Will order the tools required for this and when / if I'm successful I'll create seperate thread under guides as there prolly are peps still trying to unlock.
[Huawei Mate 10  Questions & Answers] Pretoriano80:
I doubt that the burn-in is because of the old firmware, probably the oled panel it's getting old.

You should do the other way around, first send it to Huawei for a display replacement and then get the unlock code.

The procedure it's not really easy and the water resistant part it's the last of your problem, first you must make sure that you don't break the glass back cover when you open it up. xD

Probably Huawei's repair center won't even bother to replace the display only, but they will replace almost everything, so you would endup with a locked bootloader again.
[Huawei Mate 10  Questions & Answers] Rstment ^m^:
The display literally burned in couple months after I boguht the device and and we still had the emui 8 only. Replaced it and switched to the 9 the same month. All was good for a year or so untill they replaced motherboard. Now the same thing all over again, few months have passed - literally 2/3 months and the screen burned in again at the same spot - navigation bar.

The opening part doesn't look that complicated, was thinking of buying a heating plate, heat phone to 120°C and go back and forward cutting adhesive then heating the phone again. Should be fast and efficient this way.

The finicky part that I'm worried about has to do with bricking the device or shorting the motherboard in some way '-' Maybe service also uses some repair stickers that aren't present on any of the guides and will get dmged when I open the device - after all, I took the device for repairs under warranty at least 5+ times by now :cowboy:

Last time for the replacement they indeed replace almost everything - display, battery, back cover, new frame - essentially a new device w same motherboard.
[Huawei Mate 10  Questions & Answers] ante0:
Also, if they do replace stuff the code you get through DC will not work.

It works by modifying some strings in the oeminfo partition, so if they were to wipe and reflash everything your code would be lost.

If they replace motherboard you will need a new unlock code.

There is a sticker on one of the screws you need to remove, so they will know you did open it anyway.

Bricking is no problem as you can unbrick using testpoint. Shorting shouldn't be a problem. I tried all the visible points and only 1 or 2 actually send current back so USB devices in computer restarted xD But none of them shorted my phone.
[Huawei Mate 10  Questions & Answers] Rstment ^m^:
I see on pictures online that there are some points exposed with the shield on. Will take a look at picture you posted earlier for testpoint location to determine if indeed you can access it without removing the shield - hence not touching the stickers you mentioned - ty!

Wdym by losing dc unlocker code tho?

Does it not read the bootloader code of the device - meaning after they wipe / flash their stuff I can use the same code again to unlock via fastboot?

Or can it not read the code and just modifies the nvme files or whatev inside the partition to allow for a custom bootloader code?

Thanks for all the info! Will go look now for the picture then decide whether I'll open before or afterwards depending on the position of test point.
[Huawei Mate 10  Questions & Answers] ante0:
When you use HCU to get code it writes stuff to oeminfo, replacing 2 strings with "DC-UNLOC". So that's used in calculation of code. If you flash back stock, unmodified, oeminfo after using HCU you won't be able to use the code it generated.

Testpoint is located under the shield, so it's not possible to get to it without removing the shield. I have my phone with shield on infront of me. And I can't remember which screw had the sticker on it. If it's on one of the corners I guess you could try to bend it up to get to testpoint.
[Huawei Mate 10  Questions & Answers] usafle:
I just can't understand why the won't release the bootloader unlock at this point? The phone is now 'outdated' and old.... where is the harm?
[Huawei Mate 10  Questions & Answers] Rstment ^m^:
Thanks but I'm still having hard of a time following ?

After you use hcu it modifies the oeminfo to get strings it needs for calculations - You get the code aftwerards and your oeminfo is modified, right?

What I don't get is how flashing stock makes code unusable tho?

Is it not original bootloader code we'd get if Huawei site was still up? That code should be usable even after all modifications were reflashed with stock, no?

Or is it a custom code that depends on modified oeminfo to work?
[Huawei Mate 10  Questions & Answers] ante0:
It's a custom code. If you use HCU to generate a code it invalidates your stock code. If you flash back stock oeminfo you can use the code Huawei gave you but not the HCU code (until you use HCU again to generate code).

Iirc on Kirin960 (and probably below it) you can use both HCU and stock code, so it uses another way of generating it I guess

Has anyone tried this approach for a MATE 10? or would you recommend it?
[Huawei Mate 10  Questions & Answers] geogsm_1:
What method are you talking about?

If through testpoint, then yes!

Everything works perfectly
[Huawei Mate 10  Questions & Answers] FUHuawei:
Yes, of course, I meant through test point. Do you know of any good step by step guide on how to do it? I want to try it and post here my results, if everything goes well I hope everyone ditches huawei software.

Also, I have searched around for options regarding ROMs, does anyone recommend anything in particular?
[Huawei Mate 10  Questions & Answers] geogsm_1:
Yes, I know the method) and have long written instructions on another forum with the permission of my teacher.

Decision made

On Huawei Mate 10 / Mate 10 Pro /, you can get the bootloader unlock code using a testpoint. But you need to have a programmer such as MRT / SIGMA / HDE / HCu-Client

[Sony Xperia XZ2 Questions & Answers] fungo45:
All of a sudden, my microphone does not work in a call. Regardless of if I originate the call or answer a call, the other party can not hear me. Works fine through speaker phone or Bluetooth. I've searched as much as I can online for a fix, but no results. So far I have done the following:

-Installed a third party phone app

-Tried safe mode

-Tried to repair in the Xperia Companion app on my PC (actually made things worse - couldn't make or receive calls)

-Full restore to factory defaults (fixed the call issues, but not the mic issue)

The tests in the support app fails to hear a frequency change.

Since the microphone works in speak phone, I assume this is still a software issue and not a hardware issue (unless the speakerphone uses a different mic).

I'm stuck and could use some advice.

Thanks

[Google Pixel 3 Questions & Answers] theGekkoST:
Still happening for me. I can't open any other app or swipe to a different screen right away after swiping up to go "home". I have to wait for that stupid corner animation.

- Edit: Looks like it is only still an issue with 3rd party launchers like Nova. Still BS Google has buggy launcher issues with Gesture Nav.
[Google Pixel 3 Questions & Answers] samnada:
Yep, same, running Nova. Unfortunate lag. Also, if I'm in the App drawer swiping up doesn't return to home screen, it brings up "Search Apps" screen. Have to swipe back from the App drawer to get back to home.

Edit: Question, what's the purpose of flashing those bars in the corners with the resultant delay in running apps? Is there some functional purpose, or just a constant reminder that the Assistant can be accessed swiping the corners?

Edit: Fixed the App Drawer issue with swipe up not returning to home. It was a Nova setting. Also, reported delay issue to Nova and they responded it's a known issue with all 3rd party launchers, and hopefully Google will fix it in a future update. One work around is to use back swipe to exit apps to get back to home which avoids the delay.
[Xiaomi Mi A3 Questions & Answers] jtcp2703:
Hi, I'm having trouble with Magisk re-installation.

First I installed Magisk using the flashing boot.img method, it was working correctly but I tried to remove the youtube vanced module, when it asked for a reboot it went straight to the bootloader, I just re-flashed the original boot.img to the phone and got it working again. the issue came when I tried to reinstall Magisk from scratch again. Whenever I tried to install it the process would go without any issue but when I tried to start the system it is going to the bootloader again.

I tried installing twrp using this guide and got the custom recovery working on both slots, then I tried to flash magisk using the zip file, the installer ran without throwing any issues but when I tried to reboot again to the system it still goes to fastboot, this time not only corrupting the system start but also the twrp recovery. I haded to reflash the stock boot.img image on slot A and the twrp image on slot B to re install twrp on both slots.

Also using the TWRP tried running the uninstall magisk zip but whenever I try to run it it just fails because it cannot find the magisk.img file and exits by telling that I have not installed magisk.

Tried erasing the folders inside of /data/adb but its the same issue all over again.

Does anyone has any idea or suggestion on what could I try to fix the issue?

Thanks
[Xiaomi Mi A3 Questions & Answers] _mysiak_:
Try flashing patched boot image (the same version as your system) and boot into the system, go into magisk manager and do complete uninstall. Or download the latest Magisk uninstaller and try from TWRP again. Recent versions of Magisk ditched magisk.img, so you might be using old version of the uninstaller.
[Xiaomi Mi A3 Questions & Answers] jtcp2703:
Tried using the lastest uninstaller found on the topjohnwu/Magisk repository, which did not show any error but after installing magisk the phone still goes to bootloader, then tried to run the uninstaller again but it only works on the b slot and to run it on the a slot I have to reflash boot.img and then install twrp on both slots.

But thanks for the sugestion.
[Xiaomi Mi A3 Questions & Answers] _mysiak_:
I would restore stock ROM, skip TWRP installation and flash just correct patched boot image.
[Xiaomi Mi A3 Questions & Answers] jtcp2703:
Do you know where can I find the lastest stock rom? Right now I'm on 10.3.9.0 PFQEUXM, or if the lastest is not possible, could I flash a older version of the rom without any trouble?
[Xiaomi Mi A3 Questions & Answers] _mysiak_:
Try to find the full OTA zip for the latest version (or at least the same you have) and extract it with this tool https://github.com/cyxx/extract_android_ota_payload

Xiaomi hasn't released the fastboot rom for the recent updates yet.

So far I was able to find only global links here (they should work too, but rather backup your data first). http://4pda.ru/forum/index.php?showtopic=962154

You might have luck installing older fastboot EU ROM, but again, backup your data first.

If you did not enable "allow system modifications" in TWRP, it should be enough to flash only stock boot image (there are links to them somewhere on this forum).

Also I would avoid installing TWRP.
[Xiaomi Mi A3 Questions & Answers] _mysiak_:
There are usually two types of OTA zip files, small incremental ones (which you described) - for monthly updates and full OTA (1-2gb in size) - for direct update across several versions. You can create all needed fastboot images from the full OTA payload.bin with before mentioned python extractor script.
[Xiaomi Mi A3 Questions & Answers] _mysiak_:
By wasn't able to restore you mean that you couldn't convert payload.bin to fastboot images, or that converted fastboot images were not working?

I've just extracted these files from payload.bin from the link you provided (with this app). I don't have a phone to test them though (I did the same thing a few times on Mi A1 and flashing, phone and OTA worked afterwards).

I used to be able to receive calls while the clamshell of the Universal was closed with the screen inside. I prefer to carry it that way because I consider that the screen is more protected by the hard case. It worked fine for over a year, but now, when I hear the phone ring, pull it out and press the green button, there is no sound and the mic doesn't work either because the caller can't hear me even though they know I have picked up.

In order to operate the phone on receiving a call, I now have to spin the screen around and put the screen side to my ear.

Is this a hardware fault, or might a hard reset help here. I am a bit reluctant to do that because I'll have to reinstall my applications and settings.

Thanks for any insight you can bring to this issue.
