Hi,
a friend of mine has got in China a P7 with a strange EMUI 2.0 firmware (I always knew that P7 came with 2.3 since the first version). I wanted to upgrade it to the EMUI 3.0, then I downloaded the package from emui.com, I extracted the dload directory and copied to the internal memory (the same procedure I succesfully did with mine) but when I booted it holding Vol-, Vol + and Start button I just went into the stock recovery interface.
I though was a problem of the recovery, then I restarted with adb into bootloeader mode but the screen was all empty except for "fastboot mode" wrote at the bottom. When I tried to flash another recovery I got an error saying that flashing the recovery was not allowed.
Anyone knows what the problem is?
Thanks in advance
locked bootloader..

And also is resisting to any attempt to unlock: do not give Product ID so I cannot produce the unlocking code, neither are working all methods I found on the web. I may have to give up
maybe there is a firmware for your p7-L07 like there is for the p6-u06 where you can flash a so called unicom version and first downgrade and then upgrade/update..
and hopefully this downgrade unlocks the bootloader..
just my thoughts..

Thanks blueIBI, the problem is how to flash it, since the normal way do not work. After copying the dload directory on the phone memory, if I use the system menu to perform local upate or I reboot by pressing Vol+ Vol- Start I always end up in the recovery menu, the firmware gets never installed.
Will try harder.

Are you sure this is original P7 not some chinese crap looking like P7?

The phone belongs to a friend of mine. I own another P7 and they look exactly the same. It came in the original box with everything, so I have no doubt that it is original.
The fact that it has EMUI2.0 make me think that it was one of the first released to the market. The phone is working fine, just it is not upgrading on-line and I cannot find a way to upgrade it manually. I will try contacting Huawei support.
Hey all.
I am trying to unroot and re lock my bootloader so my phone is back to its normal state
I have wiped all data on twrp and re flashed with 136.
That isn't the issue,
Whenever I go to change the theme it doesnt let me, the stock icons are big and ugly and werent the stock ones I had before.
Does anybody have a guide on how I can remove all traces of this root because its not letting me get rid of these ugly icons.
Reflash from externe SD card ?

I think that what he said is this:
- Create a dload folder on sd card root
- Copy update.app (from 136) to dload folder on sd card
- Force an reflash: power off, then vol up+vol down+power
- After flashing, go to huawei updater and update to the last official version for your phone
This is what I've done with mine. And ended with bootloader locked and everything as factory again.
Hope it helps, but if you search the forum you will find a lot of info about this procedure.

If u wipe data and flash u need to include the hw folder to with the firmware in dload folder when u flash to get rid of the ugly icons and get Themes to work.

You have to flash stock recovery via fastboot before this method of complete reflashing firmware. Otherwise flashing process may fail and end up on eRecovery screen.
I got a free P9 from a family friend so i decided to tinker around with it.
I successfully unlocked the bootloader flashed twrp and installed SU on it but then I wanted to try the unofficial CM rom on it. But I wasn't getting any signal with it so then i tried to go back into stock firmware which was posted on xda (at the time i didn't know i had the wrong model). After that Playstore wasn't working so tried using another stock firmware that was on xda but then i found the right model that i had (VIE-AL10C00176) but now it's stuck in a boot loop. It would boot up (doesn't show that i have an unlocked bootloader anymore) and then it would restart. Occasionally it boots up into erecovery. I've tried downloading "latest firmware and recovery" from this but it's still stuck in a boot loop. Any idea how I might fix this? (lack of hindsight cause i've done this a lot on other phones but i didn't prep a back up). I'm pretty sure I left USB debugging on before all of this I have yet to test if i can reflash twrp and try flashing another rom to see if this fixes anything (any thoughts?). Any help would be appreciated thanks.
Hello. I would try this way:
1. download a complete dload version from http://www.huaweifirm.com/firmware/p9-plus-vie-l09/
2. unzip it, inside there is a dload folder..
3. format a micro SD card and copy the dload folder on it
4. shutdown the phone. If it does not shut down don't worry.. go to next step
5. insert the micro SD card
6. keep pressed all three buttons (volume+, volume- and power) until it starts flashing
Let me know if it works..

Many people have problems to get back from C432B336 to C432B160/151/etc. so I decided to briefly explain, how to rollback using official Huawei tools. I am not responsible for any damage, soft bricks, hard bricks, etc. Internal storage will be wiped clean! This method worked for me, I did it twice on L31 and L21, both times without any problems. All firmware files come from official Huawei support for Germany, UK, and Poland. Here we go:
1. Preparation
A few things are necessary before we can rollback:
SD Card (needed to apply update)
Huawei Rollback File
For L31C432 (EU): http://download-c1.huawei.com/download/downloadCenter?downloadId=93787&siteCode=de
For L21C432 (EU): http://download-c1.huawei.com/download/downloadCenter?downloadId=93800&siteCode=pl
For L11C432 (EU): http://download-c1.huawei.com/download/downloadCenter?downloadId=93764&siteCode=uk
Full OTA Software File (for the system You want to finally end up with)
L31C432B160: http://download-c1.huawei.com/download/downloadCenter?downloadId=93803&siteCode=de
L21C432B160: http://download-c1.huawei.com/download/downloadCenter?downloadId=93802&siteCode=pl
L11C432B161: http://download-c1.huawei.com/download/downloadCenter?downloadId=93804&siteCode=uk
PC/Mac and USB cable
2. Going to C900B300
Rollback file will change Your software info to C900B300. As far as I know, this is a specific firmware key, that alows to fully update firmware to any other version. What you need to do:
Download and unpack Huawei Rollback File for Your device (links in chapter 1)
Copy "dload" folder from unpacked file to Your SD card
Turn off Your phone and turn it back on, holding POWER, VOL+ and VOL- buttons
Now, Your phone should apply update from SD card, and reboot
In Your phone, go to "Settings" -> "About Phone". If Your software version is LXXC900B300, everything is fine, and You can proceed
2. Switching to Marshmallow
Download and unpack Software File for Your device (links in chapter 1)
Remove all files from "dload" folder on Your SD Card, and copy "UPDATE.APP" from the file You just unpacked to this folder
Turn off Your phone and turn it back on, holding POWER, VOL+ and VOL- buttons
Now, Your phone should apply update from SD card, and reboot
Second reboot may last a while, but eventually You'll see a popup informing about removing user data
Next reboot will bring You a fresh install of MM,
Done
Again, I'm not responsible for any bricks, crashes, etc. If You want more information or help, please, leave a comment in this thread.

Hmm, update process of rollback file went fine, but in settings>about, it says build number is NRD90M test keys..
Should I proceed to next step?
EDIT: never mind, I did second step, and it worked like a charm

It works with unlocked bootloader?
I failed on the first step, it says "Software install failed! Incompatibility with current version. Please download the correct update package." I'm on VNS-L21C432B336

Try downloading rollback package for Your country, maybe that will help. You can find them on Huawei support site.
Did it yesterday. Works perfect for me. THX for the links
Done today and it worked perfectly (rollback from c432b335 to c432b161).
Bye, folks!
First file installed, rebooted... stuck seeing the Huawei logo... :/
Edit: it booted but the build number says i'm on test-keys and still android 7...And missing half of the apps
So I don't know if I can continue with the rollback

At the moment I'm not so sure anymore! But I am sure I used the L31 version, which is the one I need...
Edit: solved! See this thread
I can't downgrade to 6.0
It always fails when I try to apply the first step, and I can't find an package for my country(Romania) VNS-L31C432B336. I tried all the possible packages, and it doesn't work...
I can't downgrade to 6.0 too...i fail the fist step(the install upgrade goes well but the reset doesn't), i'm quite sure i used the right rollback package. I'm now stuck, hiSuite doesn't work(it doesnt' recognize the device or something like that) eRecovery cannot retreive the package to reset. I really don't know what to do.
Update: the phone is not bricked,there's some part of a OS similar to android,witout keybord, navigation bar and notification bar. Is it a clone??D: i should have wiped cache and factory reset(somehow)but nothing seems to work, everything fail.

That is really strange. I received an answer from them the very next day after I sent my e-mail describing my problem. Then it was just a matter of a few hours and constant e-mail exchange with them, talking about the problem, and eventually they found a way to fix it and it worked like a charm. The fix is exactly the same as in this thread.
Followed the guide to rollback from vns-l31c432b336 to b161 and worked flawlessly: just to give more details on the installation progress, if you see an error message during data erase in the first dload installation, don't mind it, reboot and proceed to next step, if you did follow exactly what the OP says, you will have no problem with last installation!
Thanks a lot for the tutorial, saved me lot of time and efforts!
Thanks!
works perfect!

Hi everyone,
I need to flash stock rom on a huawei P SMART 2019
Unfortunately I followed all steps on this link : https://firmwarefile.com/huawei-p-smart-2019-pot-lx1
I installed all drivers, software but when I put in donwload mode, it shows ADB interface ready but not downloading on the phone or sometime I get a fastbook status failed
If anyone had a little trick with this
Thank you.
If you’re still looking for a solution, I reverted a Huawei P Smart 2019 (POT-LX1 but may also be known as POT-L21) back to 9.1 stock ROM by:
1. Downloading the firmware from here: https://androidhost.ru/search.html
2. Putting the 3 zip files from the firmware in a dload directory on a clean SD card then putting it in the phone (please note that some documentation instruct you to put UPDATE.APP in the dload directory. This didn’t work for me.)
3. Powering on the phone while holding both the volume buttons down
The phone would reboot in EMUI recovery, check the presence of the firmware on the SD card, and install it if correct.
Hi
Unfortunately I can't test anymore since I don't have the demo unit with me but thank you

i tried some other files and find some which updates perfectly..but almost the same.. phone says:

maybe it is bricked for ever...
I hope you'll find a solution. I can't help you any further as I've spent way too much time on that ****ty phone (stay away from Huawei/Honor/Oppo in the future).
