I'm now at my wits end with no result re getting Huawei USB COM 1.0 port visible to use via the testpoint on my softbricked Mate 10 Pro..

Am now thinking I need to totally brick (hardbrick) to move forward (nothing to loose)...

Open to suggestions as to how I might hardbrick to move forward?

?
[Huawei Mate 10  Guides, News, & Discussion] DevrimSeven60:
When your device was hard brick
[Huawei Mate 10  Guides, News, & Discussion] henrysinn:
It is NOT hardbrick-ed it is softbrick-ed

All that I read here refers to hardbricked phones

My softbricked phone does bootloops.

If I can fully hardbrick it (nothing to loose at this stage) I might be able to salavage it via the testpoint
[Huawei Mate 10  Guides, News, & Discussion] DevrimSeven60:
Mate 10 pro is hard brick. I didn't do Testpoint. I don't think about doing this because it's not a solution.
[Huawei Mate 10  Guides, News, & Discussion] manager77:
Lol...this is not true...u can have access to fastboot and to testpoint....two different things...and you don't have to hardbrick the phone to use testpoint!
[Huawei Mate 10  Guides, News, & Discussion] henrysinn:
I have been accessing and using the testpoint

Please see post #252 - "When I earth the testpoint it boots and hey-presto, it does bootloops." .
[Huawei Mate 10  Guides, News, & Discussion] xuancong84:
For your bootloop, can it go into fastboot mode?

If you can access fastboot, you might be able to flash key partitions and unbrick the device.
[Huawei Mate 10  Guides, News, & Discussion] henrysinn:
Please see post 231

"Have discovered if I connect USB with phone off/charging, hold Vol- down then ground testpoint, we get a boot to fastboot but I'm not seeing COM port"

i.e. No-go / does not work :(
[Huawei Mate 10  Guides, News, & Discussion] Pretoriano80:
Ok, you don't get the COM1 port, but when in fastboot, isn't your device showing at all in Windows's device manager?

We may have now the infamous xloader downgrade brick also on Honor 9 STF since C432B376 build (which brings gputurbo on C432's STF) :

Downgrading from STF-L09C432B376 to STF-L09C432B371 with HuRUpdater gave [MENTION=2222449]Rapid81[/MENTION] a brick with a non-working/fake COM 1.0 mode.

- So same scenario than previously explained before in this thread...

Here is what I found out about Honor9 STF's xloaders:

https://xdaforums.com/newreply.php?do=newreply&p=77951088

Here is a honor 9 thread about its testpoint, IDT, BoardSoftware, DC-Phoenix...

https://xdaforums.com/honor-9/how-to/revive-dead-honor-9-hardbrick-connect-t3846500

And, on another subject (AGS2-W09) :

While waiting for some blackmarket guy to be able to provide a bootloader's unlock code for a 2018 wifi-only device (so with no Imei) ;

I was wondering about WORKING firmware downgrade methods with a LOCKED bootloader.

I found out DOWNGRADE with locked bootloader works with normal erecovery to only the latest approved firmware.

It do not even erase user data, it just downgrades !

(Successfully tested from AGS2-W09C432B15x to AGS2-W09C432B126)

[Wondering when FH's erecovery method will be public ; They sell it to upgrade but I think now It should work for downgrades too]

So I'm reading here, another way to downgrade would be, while in working/real COM 1.0 mode with testoint, to use original BoardSoftware and IDT (or DC-packed BoardSoftware and DC-Phoenix).

I wonder what will happen to the board info that are messed in the BoardSoftware flashing process for a device as AGS2 which is not supported by hcu-client...
[Huawei Mate 10  Guides, News, & Discussion] xuancong84:
Hey, in fastboot mode, you do not need to see COM port in order to run fastboot command.

As long as your computer can connect to the device, you should be able to run fastboot commands like "fastboot reboot".

Then you can run "fastboot flash ..." to flash partitions.

Or do you mean that your testpoint fastboot is different from normal fastboot, it does not accept the command "fastboot reboot"?

Maybe you can try changing the order of operations, or try other testpoints. Anyway, it is dead already, so you can anyhow try ^_^

Warranty

Sometimes they check sometimes they don't, all depends on the service center. I bricked two mate 9 phones, one they replaced no questions asked, the other they voided the warranty and I had to pay for the repairs .

XLOADER of B376 is still 00, so at least that's not causing it.
[Huawei Mate 10  Guides, News, & Discussion] oslo83:
Just to report what was actually achieved yesterday with [MENTION=1803475]manager77[/MENTION]'s already bricked C636 ALP-L29 Mate 10.

How did he bricks after he previously repaired it :

He flashed, by mistake, a PIE's Update.app in DC-Phoenix : This gave him a blackscreen on all modes.

After trying things it has no imei, no model, no vendor and no country, BUT its original serial number.

He tought he tried to flash with dload, but he was wrong as he was not using a working dload ALP-L29C636 firmware !

(For now, the only working ALP-L29C636 dload firmwares available online are exclusives on paying websites.)

And he still get a blackscreen in every mode.

It seems for now he only manages to boot in fastboot mode or in real COM1.0 mode.

So what was achieved :

1) successfully flashed with IDT a *modded* BoardSoftware 8.0.0.0xx while in real COM1.0 (testpoint).

This bringed back DC-Phoenix compatibility in fastboot mode.

This set its serial to a default 0123..BCDEF like OP.

Bootloader at this step seem to be already unlocked (with blank imei1 and a default serial) ; tested with a recovery_ramdisk partition which writes OK in fastboot.

After this step, it still has black screen on all modes, but phone is now vibrating at each boots.

2) successfully flashed oeminfo.img with DC-Phoenix.

This bring back its originals imei1, serial and model but not its vendor & country.

At this step, its original bootloader's unlock code is working again.

*modded* : I had to mod things in ALP SoftwareBoard's .xml to make it work :

- replace unix '/' by windows '\' in path name, for IDT to not throw up errors.

- correct a fastboot's img foldername which did not existed (There is at least two of them, I may have choose the wrong one).

From there, I guess the two next step should be to:

-repair vendor and country.

(May need an adb access with oeminfo binaries and root access OR a manufacture mode access whith hcu-client on a lower oreo build for compatibility)

-update its xloader01 to xloader 02 hoping this will fix its blackscreens in all modes

As far as i can understand, his brick situation was different from the one caused by the xloader, where you only get a black screen and the USB ser port. So that's why Phoenix and IDT worked for him and most likely will fail for those with "xloader hard-brick".

Help! hardbrick to Bootloop

!Sorry for my bad English¡

Hello, I tell you what happened to me.

I have a mate 10, which I wanted to do a rebrand and then a downgrade to be able to do it to double sim.

the downgrade caused my phone to remain on the black screen "No fastboot no recovery, usb be," then try through DC Phoenix to retrieve my phone. the only thing I can do is recover the fastboot and the recovery. but it appears to me with the following information

manufacturer - Huawei phones

model - Huawei phone in fastboot mode

Found Phone: ALP-L29

Model: Huawei phone in fastboot mode

IMEI: 866214xxxxxxxxx (replaced by x)

Serial NR. : 2WT7Nxxxxxxxxxxx (replaced by x)

Firmware: ALP-L29 8.0.0.131 (C636

IMEI1: 8662140xxxxxxxx (replaced by x)

MEID: A00000xxxxxxxx (replaced by x)

FB LockState: LOCKED

USER LockState: LOCKED

locked

Battery state: 3770mv

Now I can enter the phone information, the serial number is kept and the imei, previously only had an imei but now I am 2.

With the help of unlocker I was able to obtain the bootloader code and it worked, but now with the recovery that code no longer works, therefore I can not install anything else through fastboot.

And tried to install with dc phoenix but I always get error in writing the partition XLoader and consecutive files.

Nor can I install the system through the 3 buttons, nor is it possible through erecovery.

my question is, any suggestions I can make? or at least how to generate the bootloader code in fastboot mode (dc unlocker does not work). or another way to install the system without unlocking bootloader.

Newest version of DC works fine with xloader brick (no need to open phone either).

For Pie to Oreo downgrade brick you need to open back of phone and use testpoint.

DC has images that indicate where testpoint is, however, on my Mate 10 Pro the test point is located to the right of the connector. Not to the left.

It's between the display connector and the battery.

To initiate TP, plug in usb, unplug battery connector. Short testpoint to shield using a copper wire. Now device should show up as HUAWEI COM 1.0 in device manager. Plug in battery connector.

Now you can flash bootloader using DC, you may have to test all Kirin970 bootloaders. For me the one named Kirin 970 T2 3 worked.
[Huawei Mate 10  Guides, News, & Discussion] ChaseRxx:
After unbrick, can upgrade normally, right?

no risk getting Xloader 02 to 01 if upgrading ascending
[Huawei Mate 10  Guides, News, & Discussion] ante0:
You can only update to 02 xloader. Flashing a firmware with 01 will result in the same brick.

So after you have flashed bootloader images you need to flash a firmware with new bootloader in it.

And if you were on Pie and downgraded to Oreo you can flash back Oreo, as long as it's on new bootloader.
[Huawei Mate 10  Guides, News, & Discussion] ChaseRxx:
theoretically every sequential update will have xloader 02? or should I check each one individually before doing the update?

And how can i check firmware xloader inside if 01 or 02 ?

Every update after new bootloader was introduced will have new bootloader (apart from some cases).

One example is BLA-L29C432. New bootloader was added in B146. Every update after this has new bootloader, except for B148-SP1. (and possibly B147, I can't remember).

You can check xloader using the tool in this thread https://xdaforums.com/mate-10/how-to/beware-bla-l29c432b147-t3817241

[Huawei Mate 10  Guides, News, & Discussion] ante0:
Well, are you xloader bricked or downgrade (but same xloader) bricked?

If xloader brick you should only have device show up as USBSER (HUAWEI COM 1.0 when driver is installed).

If downgrade you should still have fastboot working.

Downgrade brick requires testpoint to work.

[Huawei Mate 10  Guides, News, & Discussion] ante0:
You would probably only need to flash bootloader files from OEMINFO tab (don't select any oeminfo as those will replace your own oeminfo with someone elses, rendering your unlock code useless).

Then flash update from DC, and make sure it's an update with new bootloader. I would go back to the one you had before you bricked

You're already in testpoint mode now, so you only get one shot before having to actually open phone up to get to the testpoint

This one bricks: http://update.hicloud.com:8180/TDS/data/files/p3/s15/G3747/g1699/v263512/f1/full/changelog_base.xml

Even though it says BLA-LGRP2-OVS 9.0.0.262, it's actually VTR firmware.

i flashed it two weeks ago it totally bricks my phone now i sent it back to repair...i did not know it was not a good firmware but now i do know why...

The New method of naming of those firmware is totally wrong if it was the old one BLA-L29 it could be useful , i did flash it thinking it was the good one now i will probably have a new motherboard with bootloader locked and only if huawei decides to repair because i had bootloader unlocked ...i really thinkin about leaving huawei too much pb (they not giving unlocking code anymore, the google thing with them, i paid to unlock the bootloader but since a long we cant unlock anymore even if we pay) i am totally pissed of about all of that.

PS : how did u know it was a VTR Firmware?

There are several ways to check and fot that B262 firmware in particular, there was a hint in FF itself.

Also, if you open the firmware package and look into the file "version.mbn" you will see that it's for VTR, which is P10.

As for the hint, check the screenshot and the FullOTA size (3.4gb,which is way less than usual).
