I dont need to be in hong kong to answer this question. This question is pretty obvious and from reading the radio threads, all radios work just as well. Some of them have very little difference. Easy answer...a working radio with the rom will be your answer. I've seen differences with GPS, but that will come with experimenting. Reception wise, they are all similar.
[Tilt, TyTN II, MDA Vario III Windows Mobile ROM De] bdbell:
This is news to me - from what are you saying, it would seem your location does not matter, and that all radios will work the same in all areas? Why is it that in almost all radio related threads, people are mentioning their location and sp? And I can find numerous threads where senior members say that your location does matter;

[Tilt, TyTN II, MDA Vario III Windows Mobile ROM De] thomassster:
before mods lock this thread, maybe could say one last thing. Location does matter, but when it comes to moving within a couple miles, your radio reception can change drastically. You use one radio and it works well in one area, but suck in a building. Then you use another radio in one area and it sucks somewhere else. Most radios that I've tried, they work just about the same. Some have good reception, but kills battery, but has good GPS reception. Theres no telling what is considered best in a certain area. You could talk to different people from Hong Kong, and my guess would be, many of them would give you different answers on what is the best radio. There is a belief that some radios work well better than others, but my opinion, majority of the radios work just as well regardless of location. It's when you consider the trade offs such as battery life, that extra half strength of bar on reception, and GPS is what you gotta consider.

[Huawei P9 Lite Questions & Answers] 3agl3deejay:
So, I have a Huawei P9 Lite (VNS-L21) and I have a problem: when I boot it up I see the "Your device has failed verification..." message.

I did a hard reset (factory reset) but when I boot it up it asks me for a password and the keyboard doesn't work.

I googled around and I found a lot of posts and I tried everything, no luck.

My bigger problem is that

I don't know my phone's model number and firmware version

. :( So I cand find the proper firmware to flash.

The only thing I see is the VNS-L21 on the back. Also, I took the back of and I saw two codes (I don't know if it helps): GA20 and 160521H2

Also, (with DC Unlocker and the the phone in fastboot mode) I managed to get the IMEI and serial number. The SN is: BUC4C16519008689

Now, from many other XDA posts, I know that I have to download the update.zip archive, extract the update.app file and add it to a micro sd card in a dload folder, press vol up + vol down + power and the updte will begin.

Did that but the result was "Software install failed".

I tried to use FirmwareFinder (from Team MT) but I didn't know what firmware to use, so I used this page: https://romfirmware.com/stock-rom/huawei/huawei-p9-lite-vns-l21/

I belive (from checking my IMEI here: https://imei24.com/imei_check/Huawei/) that my custom region provider code is C432 (Europe).

So I searched on the page for a VNS-L21C432B... firmware version, but I don't know what version to choose.

I attached 4 photos so you can see what I'm talking about.

So, any ideas on what should I do next? :(

Thank you!

[Huawei P9 Lite Questions & Answers] 3agl3deejay:
Thank you for the info. I read that post and did a little bit of searching but, as I said, the issue is that I don't know my phone's Cxxx code 100% (not sure is the European version, as far as I know it might be imported). Also I don't know at all the Bxxx code.

So what do I have to do in order to get the right one?

Funny! :)) I just bought it from a friend already with this problem and I'm trying to fix it. :(

[Huawei P9 Lite Questions & Answers] 3agl3deejay:
It's been some time since I tried to fix this phone because of some medical problems.

Now I'm resuming the work and I tries some stuff but no luck...

Please trust me, I've read a lot of "FRP unlocking" threads on XDA and I didn't solved anything.

Here: https://xdaforums.com/showpost.php?p=68514977&postcount=6 I saw something that I can use Oddin, but how? And what firmware to use?... :(

Also other thread said that I need the bootloader code but I can't get it from the phone.

Any ideas please!? :(
[Huawei P9 Lite Questions & Answers] 4uvak91:
Without unlocking code you can't unlock the phone :(
[Huawei P9 Lite Questions & Answers] lost3:
your bootloader is unlocked but the frp must be unlocked to , the problem is that to unlock frp must boot your device. The only rom that may fix your problem is this l21c432b370 FullOTA-MF-PV it is the PV, with this rom i unbrick my p9 lite

This rom is for L21C432B370 if your model is l31 you may brick it more or not work at all
[Huawei P9 Lite Questions & Answers] 3agl3deejay:
By the "unlocking code" you mean the bootloader code? And is there any way that I can extract it or get it some other way?

My (other) problem is that I don't know for sure what exact model is because I can't access the settings. All I managed to get with DCUnlocker is this:

Found Phone : HUAWEI VNS-L21
Model : Huawei phone in fastboot mode
Firmware : NRD90M test-keys

Is this info going to help me?

If I try your l21c432b370 FullOTA-MF-PV rom can I do something that is irreversible?

Btw, you said "it is the PV". What PV means?

Thank you!
[Huawei P9 Lite Questions & Answers] 4uvak91:
Google how to root your phone, you need imei code maybe. I can't remember anymore. And remove IMEI and S/N info, it's sensitive.
[Huawei P9 Lite Questions & Answers] lost3:
PV means point version and is used to move between android versions

If the readings are correct your rom is NRD90M test-keysand you have the l21 , so the NRD90M test-keys means that its problematic rom (it come up when upgrade from android 6 to 7 in huawei phones , if you look here you will see to many problems like your, some are lucky and fixed some are not so lucky) , what do you mean irreversible when you have a bricked phone? you can download this rom and try to install it with dload directory , i thing its the only way that you can try

[Google Pixel 2 XL Questions & Answers] GohanBurner:
Long story short, I attempted to flash the first 9.0.0 factory image and now my phone is seemingly bricked. I keep getting errors that say that fastboot can't detect the current slot. When I try to manually select the slot with --set-active=a/b it returns with my device doesn't support slots. If I try to flash anything individually like the bootloader/radio cmd/powershell just sits there with the "_" underscore blinking for all eternity. TWRP is already flashed and when I try to boot to it it sits on the splash screen indefinitely. I can't fastboot boot TWRP either because I can't flash anything. Deuce's script did the same thing. I tried 3 different cables and am using a brand new computer and latest Platform Tools.

Should I contact google for a warranty replacement? I don't have the order # but that should be irrelevant I think since this phone is still under a year old.

Any ideas????

[Google Pixel 2 XL Questions & Answers] Larzzzz82:
I hate the the windows Powershell. I always open a command window and work from that.

Make sure you have the most current drivers, and that USB debugging is turned on.

From the horror stories I've read, i always always always do an adb or fastboot devices before i do anything.

If you flash a factory image, don't unzip the file inside the factory image. The flash all.bat file expects that zip to be there.

I've also gotten into the habit of booting the phone that has just been flashed before I root it.

Have you wiped the cache's? Done a reset?

Just throwing things out there...

Good luck I hope you get it all sorted out.
