Mate 8 NXT-L29 C Bricked

[mobman]

Hi from Italy, sorry my english. My Huawei Mate 8 NXT-L29C (China - Imei Malaysia) bricked after app huawei finder firmware. I am in a screen where i cannot use the touch, but only the buttons on the side and have the options "Reboot system now" "Wipe data/ factory reset" "Wipe cache partition" Tried the cache and rebooting, didn't do anything. Tried wiping, and reboot, then i go in another page "Huawei eRecovery" where it asks to connect to the wifi and download but then throws an error message "Getting package info failed". From pc only with program Multi-Tool/HCU - phone fastboot :

Model: Huawei NXT-L29
Firmware version NXT-C900B172 (Firmware orginal ok NXT-L29C636B170/180)
Oeminfo: getvar:vendorcountry Failed remote:C
Bootloader: Locked
No root
Serial N: QHC0216313003XXX
Imei : 86840702490XXXX

Huawei service refused to seek repair can anyone tell me if it can be repaired? I have little knowledge of modding. Thanks 1000.

Mobile repair guide here https://www.dc-unlocker.com/dc-phoen...epair-tutorial but since you mentioned you are not experienced with this, be very careful before purchase.

Cannot detect device in upgrude mode... any help?


after other tests the phone revises old firmware NXT- L29C636B180 and oeminfo hw / spcseas in fastboot, but on reboot it says: your device has failed veritication and may not work properly. Any help? Thanks.

Connect phone in upgrade mode manually, it shows failed verification because bootloader unlocked.

My old mate came back alive after I was told in assistance that he was to be thrown away, thanks 1000! it worked to do with the downgrade. It is now with NXT-C900B192 old android 6 emui 4.0 firmware with bootloader unlocked without ota updates. The bootloader screen appears at startup but then starts. I hope you can update firmware.
How do i fix C900 firmware issue? impossible to make updates, originally C636 (hw / spcseas) and serial number: 0123456789ABCDEF do I have to repair with HCU or need to do something else? Need to add more credit?. Thanks.



(Sorry used traslator..)

You should detect your phone on hcu while it is in manufacture mode. See what data it shows, depending on firmware you want to flash may need to repair model/country/vendor.

I think I'll have to add more credits. I guess the problem is that I downgraded China version instead of Asia (hw-spseas 636) and then I did a manual firmware update. Serial 0123456789ABCDEF strange .. Now that the phone is restarted I have to use dc-phoenix to install?

May use DC-phoenix, may try from sd card in upgrade mode.
