Restore baseband and imei to make sim work again

Hello everyone.
I rooted my phone (os was marshmallow) with android lollipop procedure, so i soft bricked the phone.
I flashed with fastboot various versions of huawei p8 lite firmware, all of these were 5.0.1.
When I managed to unbrick my phone I found out that it can't read the sim, so I looked in settings and IMEI and BASEBAND were disappeared.
Probably direct downgrade from marshmallow to lollipop caused this.
By the way, I managed to solve all my problems.
I will write what I've done here. I hope will be helpful. To start: my model is ALE-L21 (Single Sim).
- Download B041c (if you search in google you will find various results, all taking to the same site). I'll explain this better after *
- Flash with fastboot B041c
- Download B133 (this is very easy to find, but if you have problems search in a site called carbontesla)
- Unpack B133 dload folder (you will find custom folder too, don't worry about it) and put dload folder in the root of your sdcard
- Go to Settings -> Updater -> Local Update and start B133 update. Phone will boot. The upgrade process should be done with phone chargend and unplugged from PC.
- At some points update could appear stucked (for me was at 15% and 85%) but be hopeful and it will continue (let be patient).
- Phone will boot and your sim after 4-5 seconds will work again!
* B041c is hard to find. At this time only one site have it. I can't link you this site, because the downloader you get from this site installs adware on your pc while it download B041c. I have had to solve my problem so I proceded at my own risk.
Updater will notify you about the update to B183. It doesn't worked to me! If you want to update your phone you can install firmware B171 and install it as update (in dload folder)
UPDATE TO MARSHMALLOW
- If you want to update your phone to marshmallow you have to download other two firmwares (B171 and the MM you want. I used B551)
- Put the dload folder of B171 in your sd card, turn off your phone and force flash (VOLUP + VOLDOWN + POWER buttons). It may appear stucked at 19% and 85%. Don't worry, be patient!
- When phone boot is completed, put dload folder of your MM firmware in your sdcard, turn off the phone and force upgrade (VOLUP + VOLDOWN + POWER buttons). It will take 15-20 minutes.
- When installation is completed and phone boots, turn it off again, enter in recovery mode (VOL UP + POWER button) and clear data and cache.
- Now you have a clean install of MM! However, some applications may be old (play store). If you have connected our phone to a network, play store will update automatically
SOLVE BALONG BUG
You can find easliy the solution in the forum. But to be a complete guide and make your life a lot way easier here is the solution.
Simply put UPDATE.APP of custom folder that you can find in some firmware (I used B049 custom folder) in your sd card and then update from settings or from force update. Is a 20KB file so it will be very fast to install

Hardest Bricked my P10 Plus. Can't even turn my phone off.

However, if you are watching this, it means ur phone is bricked with huawei p10 lite/p10/p10 plus
Read the replies and follow the instruction noted by @Blackball and his links.
Then you will find you self a way to restore the phone.
Thanks again to @Blackball and rest of you guys, much appreciated for your help.
What on earth is Yoroot?
So, You can't enter fastboot mode am i right ?
Do you connect usb cable to your devices before press Vol- and Power button ?
Current Situation
After the battery was dead, i actually can enter the fastboot and i used TWRP 3.1.1 for huawei P10 Plus from github. double wiped my device and by far i have entered the system normally.
However, the ROM wasn't official and i lost my warranty for unlock my huawei phone. And the custom service from Huawei said that they don't provide any official ROM Since it's Android 7.0 .
This ROM is really crappy that i can't delete/uninstall any Application i installed.(It gets reboot everytime i try to and the Application is still there even i just tried to Delete/Uninstall).
Worst of all, some options does not work properly in "Option" menu . (For example i can't access to "Developer mode" that everytime i press it it tabbed back to the former menu.)
I really hate this crappy menu so i tried to search on the internet for P10 Plus ROM so far i get B133 update ROM i can find and i tried to install it from SDcard by pressing VOL - and VOL + and Power buttom.
It says failed to update system at 5% while updating/recoverying the system.
and the ROM which i'm using was found in HUAWEI's official fan forum from Club.Huawei.com a forum belongs in china.(Rooted rom B140).
Right now seems the only option for me is to find a better ROM than this .(At least won't get me so many bugs like this one .:crying: )
and Thanks for your comment "Bigbearxl" it worked as normally it should after the battery was dead then i recharged it.
Yet Right now the PC doesn't recognize the device though Via-Usb because it's not Huawei official ROM and Hisuite helper only recognize their own ROM and the rest Phone helper or ADB can't recognize the device while The Phone is Booting normal .
And Reply to "Craphead" Yoroot is a special Root tool for Huawei P10/P10 plus made by chinese from Huawei Fan Club forum.
New Update
After rewrited boot.img though fastboot mode from https://forum.xda-developers.com/p10/help/root-huawei-p10-p10-t3589946 thanks to "yury_z, " i can start to delete files with current system, but it's still crappy that it doesn't even have camera
So i think i will try dload method to recovery my phone with firware that i found in forum.
Failed
Looks like i have to stock with that bit longer
dload with update.app method failed. and recovery TWRP install missing md5.
Unless i get System.img or i guess i can't get another system.:crying:
This work for P10plus too

Maybe you could also try installing stock firmware with funkyhuawei, it's not for free though. But dload method never works on P10/plus unfortunately.
thanks @Blackball and @Craphead. i checked both of your method but didn't work and this new twrp 3.1.0 i downloaded displayed sd card 0mb. and i followed poster's step and missing one file.
However i might found a useful Thead that might work and i'm gonna try tonight.

That is what I wrote.
It seems that firmware finder work for P10/plus now.

@Blackball not sure you what you mean by that, do you mean that you can actually use it to install firmware on p10/p10 plus now? If so how did they manage to get around the authentication issue?
I debranded my phone from L09 to L29 DualSim with this guide. It work with moded stock recoverys.

well i tried your method but there were some file that can't be downloaded from that post so i used another and,eventhough with complete files, the method i posted and i was going to use it tonight. Failed.
did all the steps from update.bat indicated and all worked fine till the last step that it says " automaticly install system" and the phone shows error at recovery.(similar to dload method because it automaticly create dload and exact those ROM files)
it indicates a big red " ! " sign and stopped. basicly i'm back to "No System Status"
The only method wowrks for my "P10 Plus" is " flash system system.img " method.
yet i don't know how to exact system.img boot.img recovery.img etc from those stock firmware like those chinese.
i have some of their rewrote roms (it's crappy because i has no default camera and it's for chinese P10 Plus A.K.A VKY_L29) .
Yet i can't find any System.img on google by far.

I haven't tried your Firmware Finder method , i think i can install crappy system.img then try your Firmware Finder method.
Because right now i wiped my system and i'm without system :crying:
Guys This Thead https://forum.xda-developers.com/showthread.php?t=2315547
tells you how extract flashable rom files from firmware update.app.
It should work but i only made to Unknownfile XX .img and i can't download his script "HuaweiFinder" from his google drive.
Holy Crap it worked, i Extracted system.img and other img from update.app by some Chinese scripted unpack script. and I'm trying to restore my device though fastboot mode with adb.

well just tried your method and at last step it says installing failed. then i reboot entered rec mode choose wipe/factory reset
wiped till 50% and stopped, it can't factory reset.
Before this method fastboot mode was " Phone unlock " " Bootloader unlock."
Now it's just "Phone unlock"
now i'm stuck at boot loop "your device is booting now" then it rebooted and back to "your device is booting now" again then automaticly goes to Erecovery mode. I have to shutdown device for now and hope i can find some solution tomorrow :S
When you try this :

It's important that you have the 3 zip files from your wanted firmware and rename them correctly. Don't mix with another firmwares.

after the failure i can't enter "Vol +" and "Vol -" and "Power button" to do dload method . When i try to do that it just goes in Recovery mode.
In recovery mode i tried to wipe data/factory reset. It stopps at 50% which is after wipe and starting to factory reset at 50% it failed.
i try to flash in system.img and boot.img yet i still can not enter the system and stuck at bootloop.

Maybe you should try to unlock bootloader in fastboot then reinstall stock recovery and try to unbrick with the dload folder method. Good luck

What do you mean with "i just updated from sd card a wrong dload update" ? Wrong firmware? And which?

Honor 8 lite 2017 build no. pra-la1-c185b220 bricked..

Hello,
My honor 8 lite was bricked recently and I tried almost every method to unlock but unfortunately nothing worked. I have my bootloader key also and dc phoenix for 72 hours but nothing working my way. Tried almost every update file available for my build and nothing worked. Help required from genius developers of XDA. My region is Pakistan.
Please anyone suggest me the correct firmware link and the whole procedure otherwise my money will be wasted.. bootloader is unlocked and frp locked..
I'm on it via PM, we'll post result once repaired with method used.
He's not replying now.. anyone else can help?
I replied 10 minutes ago..
Sorry I got it now
So, while your downloading firmwares, i'll post what I told you on PM.

Ok, so I think you did not rebrand your phone:
-You installed wrong region with FF (in fact right region but for huawei variant not honor variant). So your phone does not boot to normal mode anymore, it's normal.
-You then flashed different firmware via DC-Phoenix.
These steps alone does not rebrand your phone...
I think your honor 8 lite c185 honor variant is LA1 or L21HN (and not the huawei gr3 2017 variant).
1) Download this oreo service repair firmware 8.0.0.363(C185)*:
http://androidhost.ru/9dg
To install, you will have to boot in 'firmware mode' aka dload mode, and used an exfat formatted SDcard or USB-OTG. There is 3 flashes to do ; instructions are inside.
2)If working with this oreo service repair firmware, we'll then unlock Bootloader and bootloader's FRP, then we'll use Normal ota or twrp+HuRUpdater to update to 8.0.0.382(C185) with these 3 files:
http://update.hicloud.com:8180/TDS/data/files/p3/s15/G2312/g1699/v172010/f1/full/update.zip
http://update.hicloud.com:8180/TDS/...10/f1/full/public/update_data_full_public.zip
http://update.hicloud.com:8180/TDS/..._meafnaf/update_full_PRA-L21HN_hw_meafnaf.zip[/QUOTE]
3)OREO service repair may not work if you are still with nougat partition scheme,
if so you'll have to download a NOUGAT service repair : https://support.halabtech.com/index.php?a=downloads&b=file&c=download&id=53498
Done doing 1)
First, big .app flash via dload
Second, small . app flash via dc-phoenix as device won't boot to firmware mode
Third, big .app flash via dload
Device restored !
Honor 8 lite back alive again with oreo..
But I am going warn everyone who's new to all of this.. Don't try to update by yourself.. Get guidence from someone here and then try to update your phone only if you have bootloader unlocked and frp too..
