Hello,
It seems that many of HAM2 users have the consumer cellular variant and are irked by several modifications done on the stock ROM that one gets when he buys the phone unlocked. Many of us, including myself, would like to flash the stock ROM if possible but maybe are not brave enough to try .
Someone uploaded several versions of different ROMS on https://drive.google.com/folderview?...0&usp=sharing. So, the question is can we flash any of these ROMS on our consumer cellular variant and if so, how ? I used to have a samsung galaxy young and flash different countries ROM using ODIN so many times that I can't remember how much. I tried that because it was confirmed to work. So, can the same be done on our HAM2 ?
Thanks.

The 126 firmware in that folder is the original firmware that came on the consumer cellular version. The problem with flashing the complete 148 firmware is inside udate.app file there is a file named oem_verlist.img. The is a partition in the root directory of the phone for that img file to be flashed. when you go to update with the 148 firmware that img file realizes that it does not match the phone that you are trying to flash to and bring up a error and fails. I have tried to fastboot that img file to its partition but it will not go. Maybe I am using the wrong parition name but with out updating that partition before trying to flash it will fail.

When you say "update", do you mean clearing the OS and installing a new one from scratch ? Does that mean after the update all the consumer cellular additions will go away and there will be no trace of it ?
If updating seems difficult now for the consumer cellular versions, what will we do when they release Lollipop ?
If they do not release a cc version then I would have to extract the OEM update.app file from the huawei site to all the IMG files and fastboot flash one at a time(force flash if you want to call it). Inside the update file there will be a system.IMG, data.IMG, cache.IMG,etc

Assuming they release the CC version of lollipop, will there be any problem if some of the system files have been changed? For example, I've deleted some system apps that I never use and changed the boot- and flash-screen files. Will the update fail because of that ? I'm asking this because I saw a video made by one of the forum members here when he was trying to install the v148 update. He had to uninstall everything and return the system to default before updating. If that is so, then I guess no Lollipop crying::crying for me !!
Given that Lollipop is still some months away and the lack of any meaningful activity on the HAM2, why don't we prepare our HAM2 for who-knows-what. I'd like to get a grip on a my phone now instead of getting swamped by error messages when Lollipop gets released or we get custom firmware.
There's this thread [http://forum.xda-developers.com/showthread.php?t=2315547] which explains how to extract the individual image files from the huawei update app.
Do you have the CC version of HAM2 ? If so, will you be trying to flash the image files because extracting the image files seem straight-forward ? I'm actually a bit nervous doing it myself because I've always flashed my other devices when it has been confirmed to work. What I'm wary of is I'm not sure that the device software in the v148 update app is 100% compatible with the CC variant that I own ! How can one be sure of that ?
I've downloaded v148 update file and extracted the files you mentioned. Instead of taking screenshots of the contents of the image files, I've recorded a small video. I can see the boot.img and system.img but no recovery.img. There are also other files. Take a look at the video. The question now is what to do with these files and more importantly what are my chances of unbricking the phone if it bricks !!
It will not fail because of boot animation and splash screen change. It will fail because of missing system apps. You would need to reinstall those if the package comes as a upgrade but if it is a full download then your OK.
Dealing with extracting the files from the update.app just search for my post, I have a complete instruction guide.

Have you seen the video I uploaded ? Is it the "full download"? Can I flash it ? Will the phone brick ?
I read your posts on the subject. But it seems you have changed some system apps and the camera is not working as it should. I have already downloaded the 148 file and extracted the system.img and boot.img files. Can I flash these or do I have to use the files you uploaded on google drive ?
The question is why didn't you use the v148 stock ? I already have the v148 stock. Will it brick my phone if I flash the image files ? If not, why did you have to add extra files there such that the camera is 8MP instead of 13MP. Also, why is the hotspot always enabled ? Is that the case with people with the original stock ?
Man, I'm still waiting for your reply !

My understanding is it is possible to flash to stock if your bootloader is unlocked and have TWRP installed. Then its as simple as flashing a backup from a matching model with stock frimware. For whatever reason mtyler7807 is trying to reinvent the wheel.

"For whatever reason mtyler7807 is trying to reinvent the wheel", Ha Ha. I spent about 2 weeks working on this phone when I first got it. With this phone it has more partitions than what is included in the backup with TWRP. TWRP is made for backup and restoring the files that get changed, the other partitions don't change. So when I first started experimenting with this phone I got a full 148 backup with no data and installed it. I had problems, the custom.bin points to a different cust/us/ folder (because it is for a different carrier) , I had to rename that folder and found I have no more 4glte only H/H+, So I had to get the original cust folder from the guy and copy it to the phone. Still and only H/H+. It was okay for then because I testing. Next Viewed my system specs and saw that pretty much half half phone was 148 and the other half was 132.
I have Redone my complete back since I posted the last one with google camera with 13mp support( rather have border transparency). I made a post asking people summit backups. You have to do a little research, did my research and got help from the forum guys. If you want 148 on your CC version you will have to extract the update and fastboot img files (ex.fastboot flash system system.img). The name of the file is the partition name.
From my understanding twrp does a nand backup. Which is more like an image of nand. So restoring an image from a stock phone would also give you the stock partition table no?
It has been a while since ive played with android on such a low level. When it came time to update my HP Touchpad to JB i had to manually create the partition table manually to make it fit. Eventually a script was created that automatically made the changes to the file system. Perhaps a solution along those lines could be useful in getting the stuck firmware on the CC phones? The file system would only need to be created on initial flash to the stock firmware.
mtyler7807, I've been trying to get an answer since I first created this thread. The only reason I want to install the original huawei stock instead of the cc version is because I want to be able to download and install updates just like regular stock huawei HAM2 users instead of waiting for the CC version. So, please can you answer these questions :
1. If I follow your steps and use the image files you uploaded, will I get rid of CC completely meaning will my phone be just like a stock HAM2 phone from Huawei ?
2. Can I install Huawei updates directly, instead of having to do what you did (extracting the image files and the rest of the process).
3. If the answers to the above questions is no and no, then whats the point of installing your images files (apart from getting the hotspot which I don't use) ?
Please answer these questions unambiguously so that I and others will get a clear understanding of the reasons to flash the image files you uploaded. In doing so, people will stop creating these threads asking boundless questions.
Thanks.

Here is what k2thejx5 said after flashing a backup from a stock phone.
k2thejx5 said:
What's weird is when I flashed the stock file and tried to upgrade, it wouldn't work. The kernels were different so I had to go back to stock consumer rom. Also, while using the rom you posted.. I lost my toggles and had to use a different app. What also was very weird, after flashing back to the stock consumer rom, I had tethering! Don't get it lol.

-Do what I did makes your phone a complete oem, All that is need to be done is to flash a splash screen.
-How would I know if updates will work since 148 is the latest version for oem, can't test that tell lollipop.
-I'm not pushing anyone to install my image, I got about 30 pm's to post my recovery to enable hotspot and to get those toggles backup at the top. Alot of people messed up and lost them flashing that original twrp recovery under developer. Alot of others wanted the hotspot without the head ache of going through the research.
And for the people with problems with there phone that want 148 and updates with no problems, You should have brought a OEM and stayed away from sears or target or took it back to the store if you were not ready to take on the challenge of fabbing up your phone. Or just deal with the factory image and hope for lollipop.

Me and k2thejx5 was trying to fix the problem with the twrp recovery originally posted on this site. That one is not mine. Read the post. That firmware took our toogles away. You have to read this forum a little more.
Ok man, thanks for the reply. Two last question:
-For as long as you've been using your phone with your image files, have you been noticing problems like "unexpected crashes", trying to launch something and its unresponsive lie APN
-Is this the latest file you recommend : [https://drive.google.com/file/d/0BwnSk8BOQp3wV0JMWnJGc3RBTzQ/view]
Thanks.
I have to make another one. I created a new one with epic browser and 360 deg rotation. And I added Camera JB+. Thats the best camera add out there to me, looks just like google 5 camera. I can post image of this new one. I'll Back up my phone and clear the cache and restore it with no data so none of my info will be saved that belongs to me. then i'll setup up the phone and back it up and post.

All right then. Upload it when you're ready !
hello all... ive got a s912 box called the mecool bb2 pro and i want to do a factory reset then install the basics and then do a full backup... my questions are 1. will i have any problem loosing my root, since it came from the factory rooted i dont know what was done to it so theres that. then #2 what should i install after the reset like super su and twrp. and #3 what steps should i take to have a full backup ... i should have done this when i first got it but just got distracted lol ... now im looking to try an alternate rom that i have seen people trying and know i need a backup in case of bricking... thank you all for your help...
If it came with Root then it will be with Root after a factory reset.
To do a full backup of everything you need to create a backup with TWRP PLUS manually backup your internal memory as TWRP won't do it.
Amlogic boxes are really hard to brick, even if you do the Amlogic tools will allow to install a factory firmware through USB even if nothing else seems to work anymore.
