I bought a second hand ELS-N29 that is on EMUI 12 and the previous owner told me they flashed it. I noticed that vibration is weak except the indicator that you've reached the maximum/minimum volume, in that case the vibration strength is normal, and USB connection isn't recognized on either PC or phone and SuperCharge isn't working. When I put my phone in fastboot mode, however, the PC recognizes it and when I enter system recovery on HiSuite while the phone is in fastboot, the phone recognizes that I've entered recovery mode. So I'm thinking it's a software issue and not a hardware issue. Is there anyone that can help me with this? eRecovery didn't help. I can't seem to find C185 full OTA anywhere on the internet to try dload (I have an NM card).
If reset to factoy settings doesnt help you, it should be a hardware issue. Also be sure that you use an original USB cable + original 40W charger to have fast charging.
You also be sure that you have installed HiSuite on computer.

When in fastboot mode, the PC recognizes that there's a device connected in recovery mode and the phone does the same so I don't think it's hardware. Failure for that recognition when the phone is powered up is why I think it's a software issue. So I want to flash a full ota or any other means people might suggest here because I can't seem to find firmware for my region.

Btw could you help as i've flashed with 102.0.0.325, thinking its harmony OS as firmware database state.
But its just an ordinary EMUI 12 that i can't downgrade through HIsuite / proxy / dload.
Help appriciated.
During DLOAD i get verification error, HiSuite gives me package error.

I don't know what phone do you have, what firmware is on it now or was before you upgraded. A screenshot of About phone is needed.
The simultaneous loss of usb2.0 transfer and Huawei fast charging is a sign of triggering anti-rollback. Usually it is caused by downgrading from a version released after fixing the checkmate 30 vulnerability. Just wireless OTA upgrade to fix it， or you can purchase an harmony tp cable to restore USB 2.0 tranfer, or using a USB 3.0 cable connected to USB 3.0 port to transfer data.

I appreciate your help and managed to downgrade to EMIU 11 with HiSuite OVA 11 + China DNS. Without lan settings i had connection error. Thx a lot any way

Like to see if anyone may have a solution on how to downgrade back to EMUI 10 after a successful play store installation that eventually failed, I can not run any apps on the phone and can not upgrade. The p40 pro is an ELS-N04 C992 with EMUI 11.0.0.130.
I tried HiSuite with no luck, just the "no internet connection" and made sure the windows 10 firewall was open, it was. The firmware finder on my p40 is version 9.9.2 and most if not all the packages I check says the firmware was removed from the server!. I also tried to restore the phone from a few backups via USB but the phone does not recognize the files from the backup.
Ultimately what my goal is is to get back to the phone's original version of 10.1.0.183. Love some help on this and if someone has a solution man I would love to hear it!
Firmware finder project is closed I was told

Oh my god your kidding, so I'm stuck with a non-working p40 pro
If that's the case, (and I just read that) can you do an upgrade to a higher version or re-load googlefier to get it to work again?
Need usb adaptor. Download firmware for your device and region and downgrade via recovery options (hold power + volume up). Then use googlefier

download firmware you need off one of the many different firmware websites... might cost you 2usd or thereabouts. E.g. i found mine ELS-N29 10.1.0.114 (C636)... but thats for my specific model and region, so be careful to choose the right one or you could brick your phone

Update back to emui11 after you install GMS and conection will be fine. Use search function, because this problem is not new.

Hello.
I`ve got an question.
For some Days ago i make an Downgrade from the 196 Firmware an my P40 Pro.
The strange on the Downgrade is, that i hadn´t lost of the USB connection.
But imake the downgrade from the 11.0.0.196 to the 10.1.0.176.
This was the official procedure on the HiSuite untill the 11.0.0.176 firmware.
The Downgrade to the 121 Firmware i makes obove the Dload variant without lost the USB connection.
I have the same issue "usb is not working" I upgrade back to Emui 11 but still the USB isnt working - can you guide me how to solve it please?
UPDATE: It asked me to install another update - this solved the issue

Read Notes no. 5 here.
Hello people. I have downgrade my phone with hisuite proxy, from 11 to 10.
I didnt look good, and instead of n29 i have installed n39. on my phone is writen nx9 model so i was belived that is ok to install n39.
I have installed that version, install GMS, was working ok. I didnt look at charge, but fast charge and pc connect not working anymore.
I try to connect the phone to pc, to reinstall the right version. but no chance, i have try eRecovery, not working also,
The only thing i can access tru update otg.
I have download dload n29 emui 11, but when i try to install is not working. what can i do now to come back to normal.
to install n39 emui 11?
Many guys tried to change to nx9 after that from this point but no success. It wasn't tryed to update to the last Emui11 of n39, maybe the connection to the computers will be activated again. After that use HiSuite proxy to change to nx9.
so, should i wait? and use like this with no fast charge? or try to update emui 11 from n39
You have no alternative. If I were you I would try to update.
i cannot brick the phone?

Hi guys and girls.
I downgraded to 10.1.0.131 to install GMS, then upgraded to 10.1.0.176 (C432E7R4P1) and I can't upgrade further. "Your software is up to date". I lost PC connectivity, so HiSuite and HiSuite Proxy isn't an option for me. eRecovery also doesn't work - "Get package info failed".
Firmware finder app also not helping, "Most likely the firmware was removed from the server".
Please help me to get it to EMUI 11 to get back fast charging and PC connectivity. At this point I stopped caring for GMS, I'll just use the phone as is for a few months and then get something with Google Certification.
I've got a 256GB USB and a OTG USB-A to USB-C cable.
I found this page, but I'm not sure if I can use P40 Pro+ FW on my P40 Pro: http://huawei-firmware.com/?q=els-&load_page=search&page=1

You need to try using the Support app (now called MyHuawei) , go to support options and tap on the "Software update" button from there. It will perform a no-cached force recheck option and launch the software updater for you. Try it five to ten times.
If it still says it is the latest version then you need to wait a few days. It is well-known that after a downgrade, the latest version is not offered to prevent accidentally upgrading back to something you came off from. But it will eventually be offered again, there is just a grace period.
In the event it is not offered after a few days, and as you do not currently have USB, then you need to obtain a NanoMemory card and use dload method to load a sufficient EMUI 11 firmware (EMUI 11.0.0.151 as that is the EMUI10->11 upgrader fw).

These will not work in your current condition. You need a NanoMemory card OR a Type-C to Type-C USB cable. There are reports of successful USB connections with Type-C to Type-C cables.

NO! DO NOT DO THAT! Erase this thought immediately. P40 Pro+ differs in hardware, and has a separate identifier. Do not ever try to load Pro+ firmware on your Pro, because you will either brick it immediately or lose a portion of your camera functions, including the zoom camera, and eRecovery won't be able to help you.

You don't need it to be bootable.
All you need is a FAT32 filesystem, an USB OTG cable, a USB flashdrive, create a folder called "dload" and put update.app into there, and launch recovery update mode.

That's why I asked about the Plus software. I just tried with C-C cable that I got with the Pixel 6 Pro I bought today, only charging.
I also tried My Huawei, it just brings me to the default update page in the settings and says that I'm up to date.
Is there any solution to help me? I have got P40 Pro and I wanted to flash GMS and of course i had to do downgrade. By big mistake I flashed ROM from P40 Pro+ (ELS-LGRP6-OVS 10.1.0.136). At this moment my phone is turning on, but rebooting after 30-40 seconds. WiFi is working, but i havent IMEI in settings (empty place)...
Did I broke my phone?

So, I downgraded my P40 Pro from the latest version to EMUI 10.1.0.121 to install Google Apps. Now I can't update the phone back to EMUI 11 using Config>System Update. I don't know that much about this stuff.
My computer is not recognizing my P40 Pro, it only charges the phone. Super Fast Charging is working.
My model is ELX-NX9 (ELX-N29 in phone's box). I used Hisuite and proxy to downgrade. Everything is working in the phone. I only did one thing that I guess I'm not proud of. I changed my region from C605 to C452 (I guess that's it. It's the European version, and I live in south America). I only did this because I couldn't find a C605 ROM in the website I used. Actually there was one with version 10.1.0.180 or something, and it couldn't install Google Apps.
Can anyone give me some light about it? I want to know if I can get it all working, now the only thing bothering me is the updates and the USB. And the "Custom Version" in the phone info that reads "CUSTC605D1"

Wow. Nice! It is not so easy to repair that. Maybe you will need a NM card if your phone doesn't recognize OTG.
You need a DLOAD firmware (ELS-N04_10.1.0.123(C605)_[ELS-N04_hw_la_R2])
(ELS-N29 10.1.0.123(C605))
and write it.
