Not able to donwgrade - Honor 5C Questions & Answers

Hi to everybody,
I'm new here and hope to be in the right place.
I got a great deal with my honor5c (NEM-L51, EMUI 5.0.1). I rooted for the first time the phone two days ago knowing nothing about it, and it went perfect, my phone was rooted and so on. Then, while I was deleting the bloatwares using Root Uninstaller, I accidentaly uninstalled Huawei Home. I know, it was a stupid thing to do but I did it. It made the phone almost impossible to use.
Trying to fix the problem the situation got even worse. While I was struggling to downgrade, after having also resetted the phone to factory data, I flashed the Huawei Recovery and the Boot (both obtained with Huawei Extractor) using ADB, and now the Boot doesn't work anymore. There's only the recovery working, but it doesn't work too, actually. When I try to download the files and install them, it sais there's a fail in getting the packages info.
I also tried to install the firmware from the SD (all the procedures frome the guide in this forum), but when I start, at 5% the recovery sais that ocured an error, and it goes to nothing. I tried different UPDATE.APP files also from different forums, but it doesn't work the same.
On monday I will go to the Huawei assistance because I actually need the phone. :crying:
In the meanwhile, is there someone who may have suggestions?
Thanks to everybody,
slatko

P9 Plus: Bad Flash, can't get around it

Hey everyone,
So I got a P9 Plus and I tried to force the Android 7.0 EMUI 5.0 update on it, it didn't work..probably because I made a mistake which I'm unaware of.
Problem is, I'm away from home and I don't have the Box with me with the bootloader code, which means I can't really do it again right?
I tried using DC unlocker 2 and DC Pheonix but both failed, when I got to the eRecovery menu and tried to update from there (I used a B103 build, pasted in a dload folder on the SDcard) it says can't install update or something like that, my build before everything was VIE-L09C900B181, can't seem to find a stock ROM for that build (I gotta mention I'm really new to all of this when it comes to phone stuff, I'm used to work with CMD and Linux but this is territory unknown for me lol). Any advice? What can I do? When I try to restore it or force a factory reset it also says "Reset failed" right away...I'm lost you guy....PLEASE HELP ME
First of all if u have a P9 Plus and search for firmware in the p9 forum you are in the wrong place.
Did u ever made an OTA? I think dload tries the internal storage first so maybe this is why your dload attempt did not work - try formatting internal storage with fastboot (dont know if u can)
Basically you just have to find the right firmware. Maybe you need to downgrade first.
But again you are in the "P9" forum so you are probably wrong since you are talking about an "P9 Plus".

My bad, guess I didn't do enough research to see that there was a P9 Plus section, sorry about that.
An OTA? Sorry like I said I'm pretty new to this, I had the build that ends with 181 and I tried using the 103 build but I always get errors, can't seem to find a 181 build online to download.
Thanks for the reply by the way

Try dc-phoenix but be careful with factory flash. avoid it if you don't have all partitions backed up.
I had to flash it with factory soft and now i stuck with unbricked phone but not being able to make phone calls

Weird error on Honor 5C LEM-21 TWRP boots but stock recovery does not.

So, i tried flashing meticulus ROM by This guide, but it said that other version of recovery is needed which is meant for P9 lite and it should work on 5C. Then i did read that it does not work on EMUI 5.0+ and i did restore my old rom back. But the weird thing is that, my sound, microphone, video playback and nothing of those features work currently. Everything else works fine. I tried restoring OEMinfo, trying the dload method and such but nothing is making me able to downgrade. Has anyone has any similar problems before, because i checked that my OEMinfo is right but dload says "incompability with current version" so im unsure whether the problem is with the UPDATE.APP or my phone. TWRP works and i can flash things with it, but i'd rather rollback to the original ROM so i can install Lineage OS. The funny thing is that i tried flashing this multiple times but it will not boot but hangs on "Your device is booting": https://forum.xda-developers.com/ho...covery-stock-recovery-download-honor-t3521504
Camera isn't working either. Tried flashing Elite ROM to see if that works, but ended up in a bootloop. eRecovery does not update via wifi because it says that "cannot get package info" or something similar.
I flashed the oeminfo zip and tried to restore old nandroid backup. Now it only boots to eRecovery and says "getting package info failed". It's not booting into fastboot either nor recovery.
Managed to get into fastboot, but can only gain access to the product ID via software i guess and cannot get key without that. So now im stuck with locked bootloader, without rom and a stock recovery that is completely useless. Does anyone know if huawei support can help me?
They can help.
But you cam try dload method. There is a quick guide in my signature for the same. let me know in case you need any further information or help

Actually there was some problems with the internal memory. Im not sure if i did damage it or did it have something to do with faulty hardware.
Anyhow it passed warranty so i did not get charged anything. Maybe i'll keep the phone as stock for a while at least

Need help fixing phone

Good day. I have the Huawei P9 EVA-L09 model and my build number is C432B386.
I tried rooting my phone a couple of months ago and failed, so I gave up. Yesterday I tried flashing TWRP, it said it was successful, but while trying to enter it, I always get the "Your device can't be trusted... Your device is booting now." I completely gave up on rooting or flashing another ROM so I went to relock my bootloader. It was successful, but while the factory reset part, I got an error in eRecovery (Package download failed or something like that) and after that I restarted my phone and it was factory reseted. My problem is, eRecovery now says that my partition is heavily damaged and needs a wipe. So I tried doing that and it failed again. Now I'm left with a Huawei P9 that doesn't have any stock apps and I can't activate bluetooth (and who knows what else doesn't work but I haven't discovered yet)
If anyone could help, I would be grateful. I don't even know where to start fixing this. I just want my phone back or the MagicRainbow v3 ROM, but I'm not skilled enough to fix this alone.
I am just a beginner, too, so maybe you should wait for more experienced answers...
I would try to find the original images and flash them via fastboot. As far as I understand it, this would fix the corrupted partition.
But again, I still have little knowledge and an almost bricked phone!

The partition is fixed, thank you. But I still have a lot of problems. My bluetooth won't work and I no longer have any stock apps. I don't know what to do...
Could you tell we, which ROM you have installed? Is it the stock-ROM, or MagicRainbow? If it is a custom ROM you might need a gapps-package like in LineageOS...
If you want to get back to stock, you can create a dload folder in your sdcard and put the update app in it. Than a restart with a special key combination (power, vol down and vol up I believe) will install it.
I'd strongly advice you to read in this forum how to do this, as you need the right recovery corresponding to your ROM, as far as I understood.
I did this with a wrong ROM and now have a phone with no keyboard, only google voice recognition... So be careful!
I would download and install by DLOAD folder the downgrade package... Then flash a full firmware b136 or 182
But you have to be on cust c432 as far as I know.
There are a lot of info regarding dowgarde to MM. Look for it and take your time to be sure the steps to follow

Soft Bricked P9 L09 C150

UPDATE 2: Some things can not be fixed without proper tool. All i am left is to send it to service.
Which i did. Talked with a guy, explained and he told me he need to see it and test it with some tools. If can be fixed COOL if not i will sell it for parts and **** myself. Apperently some things need to be left to proffesionals.
PS. Will never get Huawei again
UPDATE: After trial and error i have TWRP instaled. Problem is i can't flash any rom because i got failed to mount /cust ,/vendor/ product (invalind argument) error. Also can't find stock flash rom for L09C150
Hello, i have problem with my phone, and this is 2nd night i spend working on it. Would appreciate any help!
Phone before trying to do anything: L09C150B367, Phone is from Hungary on Telekom (Pink T logo).
Tried to follow debranding guide (https://forum.xda-developers.com/p9/how-to/guide-debranding-to-c432-updating-to-t3551523) because i am sick of not having updated and unlocked global version. It's been long since i did anything with android and root so i tried and found guides on XDA.
Steps i did: found code for bootloaded, unlocked bootloader with SRK tool and instaled TWRP. Downloaded C432 and placed to SD. Trying to force update with Vol+,-, and power combo but update stop after 5% and say invalid software version. Somewhere i read that root is needed. Tried to root with SRK (Couple of times and different guides), not working for some reason. Phone is still unlocked with TWRP. Read somewhere (it was 3/4 am this night) that full wipe might solve it (note, i could boot into old OS). Did full wipe on TWRP and voila, not working. Can't even log on because no OS detected. Tried to find stock firmware to flash from SD card, no luck. All links i found either don't work or my recovery have ,,not correct version" error.
Now i have unlocked bootloader, custom TWRP recovery and no OS..essencially highteck-flashy brick.
What i want: Stock unbranded EU firmware.
Ps. Only phone, i refuse to burn 250e
If you are kind and free and KNOW how to do this, you can contact me via Discord and talk me trought this!

Phone without OS, bricked

Hi everyone, I tried looking all over the internet for my problem and can't see to find any solution.
The thing is, and I'm going to explain from the beginning. Several month's ago I upgraded mi p9 from android 7 to android 8 via the guide that's here on XDA, everything worked out just fine. But a couple of weeks ago I was gonna restore my phone to stock, so that that I can use it as "new" as my second phone because I bought another one. The thing is, that I think I make a factory reset the wrong way, because I did it from TWRP instead in the options menu. And since then the phone just won't work. I tried flashing tru TWRP LineaneOS but it just get bootloop in the animation and then restart. I tried installing stock Oreo and stock Nougat via the dload process and it just give me error's or it doesn't even pass 5% installation and then gives errors. I tried flashing rom via fastboot mode with Hwota, ADBToolkit, and others method that I found and nothing, anything seens to work. And I really want to restore the phone so that I can use as my second phone (for work).
If anybody can help I would gladly appreciated. If I can have stock Oreo again that's fine, if I can have another rom with Oreo that would be nice too, and if the only option is to have stock nougat again, that wouldn't be a problem either. I just want my phone back xD
Thanks!
