4.4.2 (B370) only can be upgraded from B118, its the base for B370 version, same oesmbl.

So, you need to install B118 first.
->Download B118

Official B118 from Huawei French Server:
http://consumer.huawei.com/fr/support/downloads/detail/index.htm?id=24242

->->extract dload folder from B118
->paste in to external sd card the dload folder
->go to key pad and write this: *#*#2846579#*#*
-> Open ProjectMenu
->Upgrade
->SD card upgrade
Phone reboot and install B118

Now B370:

->extract dload folder from B370.
->Delete dload from B118 from the external sd card and paste the dload folder from B370.
->go to key pad and write this: *#*#2846579#*#*

In the end will be miss same apps, themes dont work, etc... or you are a lucky man/woman and your custom.bin is the same than Cust folders!

I followed instructions and flashed B370. Now my home button is not working

 

[persona78]

You have G6 L11?

 

[mamece2]

You have G6 L11?

G6-L33
"the same as L22 and L11"

 

[persona78]

Sorry, Its the same is true, but this is for Europe and files are diferent from Colombia, thats way the issue..
It does not work in L22 and L33 , although it is the same phone with the same kernel, but the provider configuration is totally different, frequencies , network codes, etc.
I did not know because no one yet with these models had reported , I found this incompatibility shortly ...
If someone able to change or create , it may be possible to upgrade .

L11 - Europe
L22 - Venezuela
L33 - Colombia
Sorry :\

 

[baronelu]

works great . thanks a lot man

 

[bugggmenot]

i updated to B370 successfuly, everything working fine except Motion Control. when i go to "Motion Control" in Settings, there is nothing there (a blank white screen).
I remember this problem was in P6 EMUI 3 too and a patch was there to fix it. any patches for G6?

 

[persona78]

Same thing goes rong. Sensors must work! Or pictures rotate?
If not, flash b118 again, than b370. Don't forget factory reset after change cust folders names.

:good:
Excellent guide, you did a summary of four different things in one and easy to understand. For your mastery of the subject I wanted to ask your help to use my Huawei G6-U00 with firmware of China, which has unlocked WCDMA 1900 MHz band, so I can not use the phone in 3G in Venezuela.
Is there a way to unlock it?
I have tried to Engineer Mode, but it asks a code that is not known Huawei (0, 0000, 1234), . Also I tried the QPST program, but despite being recognized as a modem, do not read as a telephone and does not communicate with the RF_NV_Item_Manager.

Thanks in advance!!

Hmmm, unlock bootloader, root it and do backup from your ROM. than try b136 u251 rom, from colombia. You can use g6sknife to do backup (need root).

 

[marioarnaldo1965]

oemsbl version list check error!

Hmmm, unlock bootloader, root it and do backup from your ROM. than try b136 u251 rom, from colombia. You can use g6sknife to do backup (need root).

I have Bootloader unlocked, Rooted, and CWM as Recovery.

I installed G6-U251 B136 dload in SDcard, Note ( in my U00), and gave me the following errors; oemsbl version list check error!, ?V write data error, Error; Update.app is an invalid package, Sd card update failure, SD card update abort.

I used the default recovery cause the CWM asks a zip file. and I unzipped the file and place it in the folder Dload in SDcard.

Any advice?

After you do backup with g6sknife, there is a tool you can use, is the rom extractor, is in g6skinfe to.
Extract system, cust modems.
Copy system to cmd folder, boot in fastboot (bootloader), use cmd option, than flash system if fail you need to restore your backup, because you stay with out system, if you get success, put cust and modems in backup zip and use cwm to flash it. If you get success to, you need to change cust to your provider.

problem with g6 rom

hi
i hope someone can help me with a little problem on my Huawei G6 smartphone.

the model is a G6-U10
but currently i have a U00 rom installed (B370, downloaded from the official Huawei site, probably the Chinese one)

installation of this rom went smooth, but this build has some serious shortcomings, so i wanted to install another rom. but that appears to be impossible!
I tried several U10, C00 and L11 roms, ranging from build B118, B193, B261,B330 and B370. most download from the official Huawei servers. and I also tried rollbacks, (U10 B360 to B136 and L11 B370 to B118), but nothing seems to work.
mostly i get the message "version list error" with some other things.

it's weird that i managed to install a U00 rom on a U10 device, but now it seems that i can't install anything from other models than U00 ánd roms that are older than the current one (B370), which is the problem, because this is the newest i think... so i can't find any other rom that i can install...

the phone is not rooted. i tried is with Vroot and Rood Genius, but it didn't work. why, i don't know. i don't even know what i precisely would do when the phone is rooted... but that's another story

I really want to install a proper working (preferably EU) rom on my G6, and at this point it doesnt matter to me how old the build is...

problem with the current rom U00 B370 is mostly this:
i can't add my Google account for the phones' contacts
play store can't install any apps

can anyone help me? cant i rollback to a better build or something?

First, if you have a U10 why you flash a U00 ROM? ...
Google G6 U10 b146, try to install it.
Tell if you made it?

 

[marioarnaldo1965]

G6 ROMS

There are a lot of steps to do.. Open Bootloader, Root the Phone, Install Custom Bootloader, Flash a new Rom for G6-U10.
All these Steps are full Explained in GG Development Group in Facebook.
Send a request join message, and in Pinned Post. Read , read and read. There are a lot of information and a ROM that fit your ROM. What does it mean UE in your Question? United States? Union Europa´s? the ROMS are quite different.
