Flashing through adb/fastboot - Ascend Mate 7 Q&A, Help & Troubleshooting

Quick question all,
I was previously on B145 then upgraded to B148. I didn't like and tried to go back B145 and failed. (Before researching through the forum), I took it to flash B300 firmware and was successful but stuck for more than a week trying to figure how to get out of it. Flashing KK never worked (or so I thought), so I decided to try B324...turns out, it flashed and I was on 5.1.1 C900B324. Then I tried B327 and worked for that as well. Now I'm back to B324 and want to go back to B145.
I've been reading around to start at B127 and work up from there, but no KK firmware seems to work at all...some firmwares process, but fail at 19% and some at 90%, others fail at the very start.
Now, was my mistake done when I flashed B300 while still on KK B148? Or, after flashing so many firmwares with adb/fastboot? fyi, whenever I flashed a firmware...I did (Boot.img, Recovery.img, Cache.img, Cust.img, System.img and Userdata.img)...should I have not flashed some of these images when trying to downgrade? Still looking to downgrade back to B145 presently, although there is many cool features of LP.
All the help is appreiciated.
Thanks!

I think I've tried this and all other avenues, but I'll give it a go once more.
Okay, so is this B300 the (Rollback 5.1 to 4.4)? Or (Downgrade C900B308)? Also, after the correct transition to 300, which img(s) of 137SP03 do I flash and also for B145?
I've been accustomed to flashing Boot/Recovery/Cust/System/Cache & Userdata images...should there be specific images to flash in each for 137 and 145?
Thanks for the feedback!!

Ok, just as I mentioned before.
I can transition down to B300 from B324. Extract Update.app from B137SP03 and force by 3 buttons; it loads up to 19% and then fails after. I've repeated like 5x already with same results.
I also put the unextracted B137SP03 file into dload and tried 3 button but same Failed results.
Any other ideas? fyi, my bootloader is unlocked as well.

Read this topic and try repair you phone.

Her you have twrp

And her you have supersu.zip for twrp

Do It that.
Enable debugging USB in setting
Then use twrp to install
When it's install copy supersu.zip to sdcard
Go to twrp and find supersu.zip and flash

Mi 4c bootlogo and fastboot changing

I discovered something interesting.
Bootlogos from oneplus one works for our mi4c.
You can use this tool to make your own:
http://forum.xda-developers.com/oneplus-one/themes-apps/mod-customize-ones-bootlogo-t2857153
To flash it :
splash logo:
Code:
fastboot flash bk2 logo.bin
fastboot logo :
Code:
fastboot flash logo logo.bin
For both displayed is opo splash logo, so you must make separate files for splash and fastboot logo.
Enjoy !
Also feel free to share your logos.
Mi4c original logos attached below
nice
So we can get rid of the Mi logo? Would be nice to have Android logo like most phones I.e. Samsung s6&7
Potentially yes, we only need PNG of it.

ps. i have flashed your google bootlogo in RR Rom, and it works :good:

This apply only for oneplus one, where this causes bricks on lollipop bootloader, we have mi4c, so don't worry...

@AndropaX
thanka you mate, its works like a charm
:good:
@AndropaX is there a way to flash the boot logo only and not fastboot logo? Because when using the tool, it seems it combines both into one .bin file?
I've attached the image I want to use
This tool is made for oneplus one, which has splash and fastboot logo in one partiton, mi4c has separate partitions for it. So simple ignore fastboot.png
#GETRESURRECTED
Just made this and added the powered by android to make it like other phones. Added a preview and the boot if anyone wants to try it
Nougat bootloader
Can I flash in on nougat bootloader
any idea why am I getting error something about max. storage when trying to flash logo and end up with no success? device is seen properly through fastboot devices, it used to work in past, not sure what is issue now
running official LOS 14.1 with newest firmware for it
EDIT: never mind, on the other try it worked fine, but still would prefer to know how to make flashable ZIP so I don't have to use PC next time

'Internal problem with device' warning on boot.

Hi, help please! so I'm getting an 'internal problem with device- please contact your manufacturer' on boot before lockscreen.
This is after the usual bootloader warning.
What have I corrupted exactly?? I went to LOS and back to 5.1.9...
Magisk?

This screen is being caused by the flashing of the wrong version of Magisk. Uninstall Magisk, then flash Magisk 16.4
I had that as well and to fix it I did the following (running magisk 16.7 without twrp).
1) uninstall -> restore images
2) selected Preserve AVB 2.0/dm-verity
3) install -> direct install
4) reboot
No more message and also after doing this the backups started working again under my google account.
I solved the problem bij using Oxygen updater from the playstore. Reinstalling the last update solved the case.

Going back to stock; Error 7

So as the title goes i'd like to go back to stock with root. I dont know what happened but i downloaded the OTA and install when boot. To. Recovery i encountered "error 7". Can anybody help me fix this. Am happy with stock rom and kernel with magisk.
Bump
You must install Old Twrp 3.0.1

I agree, is a recovery problem!
Which version of twrp recovery are you using?
