[Q] Problem in downgrade or upgrade firmware - Huawei Ascend G6

I flashed huawei ascend g6-u10 from KitKat b330 to jb b146. This build has some problem like it didn't activate custom version. I decided to go back to original build 135. But during install it will give an error "oemsbl version list check error".
I extract current installed update file and one of the line in oemsbl list file was b135.
I tried to install from fast boot and adb it didn't worked.
I decide to use sp flash tool and it need scatter file and I don't have and there is nowhere I can find it. I tried to use android droid tools but it can't generate scatter file I think because phone is not rooted.
I tried every tools I know to root device but didn't work too.
I tried to unlock bootloader too. I think is nessesarry for rooting but can't get unlock code.
Is there any way to forcely install b135 or b330?
Or is there any way I can get scatter file for sp flash?
Or is there any way to root o.s. ?
Or is there any way to skip oemsbl version list check during install?
Or is there any way to get unlock code.

Huawei device was read and flash firmware completely from /sdcard/dload folder ever.
I don't know this works still now, but why don't you try this?

dload Update.app method, entering TRWP instead

Hey Guys..
Bought a L29 Mate 8 last week, have been able to unlock, root but now want to install some custom roms..
The installations instructions tell me to go (back) to a stock B1xx rom through the "dload method", and next upgrade to a stock B3xx rom through the "dload" method.
I'm running stock B170, rooted/unlocked right now.
I've loaded a stock B3xx update.app file on my phone, but i'm unable to get the phone to run this update, it either boots normal to system, or when I use vol+/vol-/power it boots into TRWP instead.
Other instructions mention a setting to run update manual going through settings/update but can't find a "manual update"" setting there.
Hope you guys can help me going with this one...
Thanks
You need to flash stock recovery back,use srk tools.

That did the trick, it will "force" manual update now.
Now I run in another problem though, stock rom links for my "NXT-L29C636" are not available, link for C185B170 was still working and the only B320 stock i could find was the one shared by user "bluheart" in his signature "C185B320"
So decided to rebrand the device to C185 with SRK Tool so I would be able to flash these stock roms, first flashed C185B170 through dload method with no problem, and from there tried to flash C185B320 but update does not get passed 5%.
The rom version listed in the device is somehow NXT-C900B170, using the "* # * # 2846579 # * # *" code in dialer confirms phone is "C185 - Africa / Middle East"
Any pointers ?
(edit: tried to reflash C185B170 through download method, also gets stuck @5%)
Thanks
Now in about phone it show C900B170?
Can you get an ota update via updater?
The latest c185B200 so start from this one.
http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1076/g104/v65326/f1/full/update.zip
Or you need to root B170 and change build display and oem info to C185 in srk tools.after this you will be able to dload c185b320

Used SRK Tools to change ROM version from "NXT-C900B170" to installed "NXT-L29C185B170" in the hope this miss match prevented the update, no luck, also no OTA available.
Thanks for the link, will download this and try to get this going first...
(edit: Changing OEM, SRK Tools read the device as AL-10?, changed to C185, fingers crossed)

Yes flash b200 like you are debranding,I mean change build prop display and oem info to c185.
ro.build.display.id=NXT-L29C185B002

Had no luck with the C185 roms, they all got stuck at 5%, decided to rebrand back to C636 and dload the original NXT-L29C636B170 and that worked, so will create a TRWP backup from here to fall back on.
Will give the rebranding to C185 another try later, with the rom you provided (i wonder if i went wrong somewhere with all rom downloads named "Update.zip" I might have mixed something up)
Maybe you/anybody confirm I take the right steps to rebrand to C185 and update to the NXT-L29C185B200 ROM provided.
Using SRK Tool: (current: NXT-L29C636B170/Rooted/Bootloader Unlocked)
1-Install TRWP
2-Change OEM from C636 to C185
3-Change ro.build.display.id=NXT-L29C636B170 to NXT-L29C185170 or NXT-L29C185B200 ?
4- Copy NXT-L29C185B200 "update.app" to device/dload
5- Install Original Recovery
6- Use vol+/vol-/power to apply B200 update
8-Install TRWP/ create Backup
9- Root ?
10- Copy NXT-L29C185B320 "update.app" to device/dload
11- Install Original Recovery
12- Use vol+/vol-/power to apply B320 update
Thanks in advance....
Debranding
anyone tell where to email for bootloader unlock if website is not recognizing my phone.
updated to B200
Thanks for your help gm, just made a new attempt and now successfully picking up the updates as a C185.
Getting ready for a custom rom

what should I do

I Have a Huawei mate 8 NXT-L29C185B190. Couple of months ago I rooted my android. With TWRP and unlocked bootloader. I by mistake formated my phone with TWRP and then all my data including the Huawei mate 8 themes and icons were gone. The icons were like the older versions of android(messed up). Just a minute ago I got an OTA update. So I removed my root by SuperSU and then tried to update it. But then it redirected me to TWRP. I didn't what to do so I rebooted the device. What should I do to install the update and get stock version? (The update is not installed)

Before trying to update you might want to fix the problems of your device, get SRK Tool, root your device, then go to utilities and flash the HW Init folder, that should solve the themes and the icons problem, then flash stock recovery and then get and flash
L29 C185 B190 through the Dload method, only after doing all this you should take the OTA without issues (dont worry when you doad L29 C185 B190 root is lost).
You could also try to only flash stock recovery (using SRK Tool) and take the OTA but very much likely the theme and icons problem will still be there, if the OTA update works that is.

Oh ok. What is the hw init folder? Is it like some type of Huawei folders? And if possible can like provide a link on how to do it. I know about the flashing. Its just that I am really scared that my phone may hardbrick. I looked on XDA Developers for this stock firmware but found it on another website. But the thing is that I'm scared if that websites porvides false information

The HW_Init folder contains the folder structure needed so the themes can be applied, it also contains the default themes which are lost when you format Data from TWRP, its a quick fix and the SRK Tool makes it easier for you.
https://forum.xda-developers.com/mate-8/development/tool-srk-tool-huawei-t3369797
About the firmware you found, if you have the link to firmware theres a way to check the changelog, pass me the link and ill check it for you.

Ok, I rooted my phone(Huawei mate 8 NXT-L29C185B190)(L29B) using the SRK tool before and I did it again. So for the hw init folders I should check it on the internet right? Do u know how to flash it?
http://www.gizrom.com/huawei-mate-8-stock-roms/
This is the website that I found for my stock firmware
P.s thx for you help. I am a noob when it comes to this

Open the tool (SRK tool) then select the option 7-Utility then select option 12 and then 1(mate 8), once the process started be aware of your devices screen, it should ask for root permission for an ADB shell and you have to grant access otherwise it wont work but dont worry you can try manytimes untill you get it right, your phone wont explode o anything like that If all went well , youll be asked to press any key at the end to reboot your phone, after reboot you should be able to apply themes and icons like usual.
About the firmware, this is the link where its being downloaded: http://download-c.huawei.com/download/downloadCenter?downloadId=91645&version=357954&siteCode=pk, seems like its directly from huawei server, you could download it to your PC and explore it with firmware extractor or you could just flash it throught the dload method, if is not right for your phone it doesnt flash it.

The firmware is legit! its straight from huawei, if you download it and extract it you will see a manual from huawei telling about the update and whatnot, its safe to push through Dload.
Your welcome and good luck!
Oh thanks man just one last question before the start the process. So ehen you flash the stock firmware won't the stock recovery automatically be applied and if not is it necessary to flash stock recovery first then flash stock firmware? And theabove firmware link which u put, idit the firmware for NXT-L29C185B190 ( THE 64 GB 4 GB RAM MOCHA BROWN)
And I also heard if it is not the right version for your phone it can hardbrick it that why I am just making sure about the firmware. And when before I flash my firmware should is it need to factory reset the phone
Your welcome.

For the dload method you dont need the stock recovery, I have just learned that the E recovery its always inside the Mate 8 eventhough you have a custom recovery, so you just need to place the update app inside a folder called dload, the folder should be on you external SD card, then what you do is turn off your device and then press and hold volume up, volume down and the power button at the same time until you see a screen telling you that is checking the firmware, if the firmware is correct then E recovery will do its thing and flash the firmware, the stock recovery will be included, you will loose root and the bootloader will close again.
Or you could flash stock recovery just to be safe and then do the upgrade process (dload), you can do that with the SRK Tool, just be sure to install a stock recovery acording to your version of EMUI.
About the firmware, I cant say, I do no own that variant, thats for you to find out, google is your friend!
About bricking, you can only do that if you downgrade the wrong way or if you flash an incremental OTA file incorrectly and even then theres many ways and tools to bring the mate 8 back to life.
My advice is that if you are goin to be messing up with your device, always do it whith an open booltoader, always back up your base firmware right after opening bootloader, back up your cust, oem info and custom bin and always check that developer options are enabled and that Enable OEM unlock and USB debuggin optiond are enabled as well.
Just realized this is in the wrong segment! @Jerry77827 Please read the forum rules before posting anything in XDA, dont be impolite!

Huawei P8 (Nova) Lite 2017 Soft-bricked, No OS, can't flash any firmware

Hi, my son's phone became unusable after clicking on an MMS link. I have since been able to unlock and get TWRP installed on it. After that I am unable to flash ANY kind of firmware on it (PRA-LX2). It had already updated to the latest version of EMUI droid 6. No matter trying to flash via Fastboot, sideload or SD card nothing works. In some places I found info saying that one can't flash lower versions of Android as the latest update changes the partitions. Huawei says the latest update is unavailable for download, so no way to get it as obviously HiSuite does not work.
If anyone can help me out I'd be very grateful. If there is any other info anyone needs about this problem please just let me know and I'll do my best to find what you need to help. Thanks

Honor 8 (FRD-L09) brick help.

Hello.
I need a help with my Honor 8, it's been bricked and I honestly don't know if there is much to do in my current situation.
So the phone has locked bootloader and stock recovery.
Fastboot always returns 'Command not allowed'
What exactly happened:
I was running Stock ROM, rooted, TWRP Recovery with unlocked bootloader.
An official OTA update popped-up on my phone, I was in a rush and I missclicked (don't even ask lol) and the update started installing, I knew I'm screwed.
So I was about to play with fastboot, but it always returned 'Command not allowed'.
And probably the worst mistake happened a few minutes ago (6:00 am trying to fix it half a sleep), I was reading some posts about the dload method, >>FASTFORWARD I installed an official update using the dload method and locked my bootloader by doing this.
QUICK SUMMARY:
So I'm stuck on a bootloop.
The 3 button combo works.
Stock Recovery works as well.
Fastboot does NOT work. (I tried flashing, unlocking, temp-booting.. but nothing)
adb always returns error:
Code:
device unauthorized.
This adb server's $ADB_VENDOR_KEYS is not set
Try 'adb kill-server' if that seems wrong.
Otherwise check for a confirmation dialog on your device.
Is there ANYTHING I can do in my current situation? :crying:
Thanks in advance for any help.
Have a nice day.
Hello, as long as you have an official recovery, a proper BOOT.IMG and the dload method is working there is still a chance( i hope), the only thing you need to know is that if the firmware is the wrong for your phone it will deny it. It means that is if you try to install an android 6.0 based stock ROM over a 7.0 ROM , it will say software upgrade failed or something like that.
You need to know under which Android version you were and install the same or maybe a more recent one but not to far away from your actual ROM, try the next one. You can also try to downgrade USING a rollback package that you can download on honor official site. Make sure that's the the correct file for your phone.
Hope you'll make it bro, let me know how the situation evolve

Hi Ryan,
Thank you so much for responding.
I could see two ROM in the official site http://www.hihonor.com/in/support/
HONOR 8 Firmware (FRD-L02, C675B130CUSTC675D002, India)
HONOR 8 Firmware (FRD-L02, Android 6.0, EMUI 4.1, C675B160, India Channel)
I tried with both the ROMs but no luck
I placed the update.APP file inside sdcard but the update stops at 5% showing that it has failed.
I also tried flashing the recovery.IMG in fastboot mode.
I have lost all the hopes in my new phone
In the rescue mode it says UNLOCKED.
Please guide me with some detailed steps.
Thanks
Flash the stock recovery of the ROM that was previously installed on your phone , then with dload method flash the rollback package downloaded from honor site , and finally flash one of the two ROM, it may resolve your issue because the phone won't accept a lower firmware without flashing the rollback package first. As long as you can use dload method it should be fine.
If it doesn't work try to flash boot.img , recovery.img, cust.img, vendor.img and system.img extracted from a clean firmware downloaded on honor official site
Let us know how the situation evolve

Huawei G play mini

Hello,
I have a huawei f play mini bought in EU chc-u01 , it had android 4.4.2 i updated it to 5.1 trough dload method on ext card.
it change my model name to chm-u01 and balong310 , i search and its the rom of honor 4c and iit's compatible.
i wanted to upgrade it to android 7 installing lineageos.
i flash TWRP and wipe out everything including the os itself idk how , what's strange is i can't get any rom instalatiion whatsoever now and i dont know why
it always fails with error 7 (wich why already tried to remove asserts line on update-script file oon the rom and still cant install) it gives a error in update-script evev after edit.
idk what to do does some kind soul can help me ? thanks
Error 7 is mostly the case when you're trying to flash a ROM that was not built for your device, you can forcibly flash it by removing the asserts line.
However, there's another case where it can show up. It's when the code has a mistake, or the ROM is LITERALLY NOT COMPATIBLE WITH YOUR PHONE.
The ROM has a line commanding an extraction of a compressed file, the file I corrupted, or there's a mistake in the code. It can cause error 7.
The ROM is trying to extract a file to a block device, but it fails, because that block device is not compatible with the file, or too small to absorb the file. For an example, 2014's low-end Samsung phones had a maximum size of 8 MBs (maybe 12?) for the kernel, so trying to flash another device's ROM will not complete successfully, because the boot.img cannot be extracted/flashed.
You need to update your bootloader.
You may have to use another recovery version with a stable tag.
Your /system filesystem is probably messed up, you need to format it to its default EXT4 files filesystem.
Flash stock ROM.
Use a PC tool to flash ROMs.
Helllo and thanks for your quick the answer.
i also tried with sp flash tool, but i did not suceed. i cant find a working stock also .
