[Huawei Ascend Mate 2] divineBliss:
Make a backup of your current setup, then follow this :

https://community.gethuawei.com/sup...15/06/30/mate2-android-l-update-now-available

I started with B148 stock and it worked for me. Make sure you start with a stock recovery.
[Huawei Ascend Mate 2] cypriotxx:
Okay starting all fresh again ,

i have downloaded all the files and got PDF open , as far as it goes says copy the two file under dload folder... the only thing here is which stock recovery i should be using ? can you send me the one you used please for B148?

so using that ?
[Huawei Ascend Mate 2] Moody66:
Yes you have to be on stock recovery. The Google drive posted has all the firmwares and recoveries listed by name. Other than that follow the instructions on Huaweis update page.

hi there both ,

sorry for the late reply , i have attached the image here for you to see, seems nothing happening just error

i have download the files few times just in case if error but still the same,,,
[Huawei Ascend Mate 2] divineBliss:
Nice image. Give details of what steps you were doing when the error occurred please. ;)
[Huawei Ascend Mate 2] cypriotxx:
1. install the recovery image mentioned

2. copy and paste the dload folder from the b322 RAR file on SD card (root) and put on the phone

3. press and hold the v+ v- power button same time until the recovery starts and this error shown...
[Huawei Ascend Mate 2] divineBliss:
When it's says to press all three buttons, the phone is not supposed to be going to recovery, it's supposed to go to the software upgrade screen as shown in the directions. Try again.

You have the two .app files in external SD /dload folder ?
[Huawei Ascend Mate 2] cypriotxx:
mmm do you mean the screenshot i attached is the software upgrade page ? if so i am calling it wrong :)

yes thats right two APP files in that folder and still no joy :(

you not located in UK any chance ?:)
[Huawei Ascend Mate 2] divineBliss:
Sorry old chap, I'm not in the UK at the moment, but if you send me a ticket, I'll be there in a bloody hurry :) .

What is the exact model # of your phone, bloke?
[Huawei Ascend Mate 2] cypriotxx:
hehe you are a star :)

the phone is Mt2-L03 Consumer Cellular bought it on ebay from USA
[Huawei Ascend Mate 2] :
Your previous comment doesn't show a screenshot. Can you try again so we can see what you are seeing?

Edit: Disregard. Just saw it. Tapatalk was moving slow lol.
[Huawei Ascend Mate 2] divineBliss:
Okay, you currently have the B148 recovery and stock firmware on phone?

The screen shot you gave is of recovery, not software upgrade screen. Turn off the phone and try the three button step again.

---------- Post added at 08:09 AM ---------- Previous post was at 08:07 AM ----------

See post # 84.
[Huawei Ascend Mate 2] :
Yea, saw it already.
[Huawei Ascend Mate 2] cypriotxx:
Phone had B147 on it before and i managed to install B148 stock on it and it works but not none of the rest.

i have tried few time and it is coming on to this page for this stock recovery version!
[Huawei Ascend Mate 2] :
Power off your device and wait until it's completely turned off.

Press and hold the power button, volume up and volume down buttons. Do not release any buttons. When you see the Huawei logo appear on the screen then and only then should you release the power button but still pressing and holding the volume up and volume down buttons. Do not release the volume buttons until you see the emui installation screen appear.
[Huawei Ascend Mate 2] cypriotxx:
okay i can see now and this came up now

http://www.huaweiblog.de/wp-content/uploads/Huawei-P8-Firmware-Update-Fail.jpg
[Huawei Ascend Mate 2] :
Did you modify your system in any way? If you did you need to restore with a system backup that is not modified.
[Huawei Ascend Mate 2] divineBliss:
cypriotxx,

Do exactly as SHM wrote. I smell success shortly ;) . Then you're buying us a pint of lager.
[Huawei Ascend Mate 2] cypriotxx:
modifying the system ?

after installing the b148 all i been trying is to upgrade to lollipop lol :) didnt modify anything ,

hehe i hope i can and you shall have a 5lt one :)
[Huawei Ascend Mate 2] divineBliss:
You have the files on the little micro SD, not internal storage, right? How many times have you tried and got the upgrade failed? Try again.
[Huawei Ascend Mate 2] :
Then its partition size related. This thread makes it possible to convert the device to standard OEM by resizing the partitions accordingly to allow the ota to properly install. You need to review the first post and follow its instructions carefully. You have a device where the partition sizes are not properly allocated to fit the lollipop update which is why it's failing.
[Huawei Ascend Mate 2] cypriotxx:
yes thats right , it has been a few times now

what about CARBON-5.1.1 for mt2-l03 ?
[Huawei Ascend Mate 2] :
Before you try resizing your partitions according to the first post make sure the dload folder is at /storage/sdcard1/dload, and inside dload are the two required files. If they are set up properly and still fails to install then refer to the first post about converting to standard OEM.
[Huawei Ascend Mate 2] divineBliss:
First you need B322 before flashing any custom ROMs. Do what SHM said about partitions now.
[Huawei Ascend Mate 2] cypriotxx:
mmm i cannot see anything about re-sizing partitions hope it is a simple process ?
[Huawei Ascend Mate 2] divineBliss:
You already had your 5ltr? :) Post 1, steps 10, 11..
[Huawei Ascend Mate 2] :
Post one breaks the steps down and makes it really easy to follow. Just do everything it says and do not skip anything no matter how you feel about it or you will most likely run into problems. At the end of post one will be instructions to restore your stock oeminfo partition should it still fail for you. Follow the instructions to a tee and you will be fine.
[Huawei Ascend Mate 2] Moody66:
Makes me wonder if he flashed OEM.Zip...
[Huawei Ascend Mate 2] divineBliss:
Any adb commands to confirm that partitions are correct?

PS: You gonna get me a model #?
[Huawei Ascend Mate 2] cypriotxx:
twrp is installed but OEM.zip isnt installing , strange thing is it is just going back to home page of the TWRP ,,,,,

okay found a way to install OEM.zip by using this version of TWRP https://dl.twrp.me/mt2l03/twrp-2.8.7.0-mt2l03.img.html

so carrying on with steps :)
[Huawei Ascend Mate 2] Moody66:
There ya go. OEM.zip is what changes the partitions.
[Huawei Ascend Mate 2] cypriotxx:
okay now installed the B309 recovery img file and seems doing the update now for B322 ...

when this finish will i be able to install the pacROM using this recovery or i need specific version twrp if so which links pls ?

[Huawei Ascend Mate 2] divineBliss:
Great!

So where do you think you went wrong?

I was going to suggest you try PAC-ROM first, but I see you've already discovered it's the best ROM in town ;) .

Follow the instructions in PAC-ROM thread of which TWRP to use. I believe it's different than the one you have now.

See you soon at the PAC-ROM thread.

Cheers!
[Huawei Ascend Mate 2] Moody66:
So the problem was OEM.zip want flashed? And you used proper twrp to fla**** then update succeeded? So anyone else runs into your issue.

It won't cause a bad imei. But it won't fix one either.
[Huawei Ascend Mate 2] CorleReeFer:
I figured as much thanks
[Huawei Ascend Mate 2] victorhuge:
For any wind users out there, this conversion works perfectly with no issues, just remember to use the three button method to start the update and not through the android OS. If flashing TWRP doesn't seem to work, simply boot the twrp.img instead and then flash the oem.zip, you really only need it to run once. The new B322 doesn't have the bugs that I kept reading about, maybe the comments were for an older version? In either case it seems to run better overall, I get notifications on the lock screen, camera works, speaker volume is as it was. Can't comment on battery life yet as I've been using it heavily since the update.

Happy flashing!

[Huawei Ascend Mate 2] Davinci50:
I just saw my guy is now a price gouger:mad::crying:, he raised his price to $70.00 US. I used him 8 different times with NO issues. :) Used to be $2.99

here is his link.

http://www.ebay.com/itm/Consumer-Cellular-USA-Unlock-Huawei-Ascend-Mate-2-Unlocking-Code-fast-/281636503246?hash=item4192d7fece:g:V~cAAOSw6aVUqVVC
[Huawei Ascend Mate 2] Nikon5400:
Interesting. I have CC version and it used to prompt for the unlock code when I have non-cc card in. I ordered the code through ebay and in meantime I followed the instructions here and updated to lollipop.

Today I inserted T-Mobile sim and went ahead with conversion.

I kept dismissing the prompt to enter unlock code and now it doesn't prompt any longer. If I remove the SIM card and reboot, the sim card icon with an explanation point is displayed, but when sim card is inserted, the sim card icon with an explanation point doesn't display, but "Settings-->Data Traffic Management" says "No Sim card". I tired univision card, same thing. Tried these SIM cards in another phone, they work fine. Any ideas what could be wrong?

When I insert CC card it is being recognized (I can see "Data Traffic Management" and APN settings)

I believe univision sim is slightly thicker than t-mobile. It also seems like both, univision and t-mobile sims are much thicker than consumer cellular sim..

Could I permanently lock the phone by dismissing that message? Or did some pin break (or being moved by thicker sims) and that causes issues t-mobile\univision cards, but works for CC? Or could the update to lollipop cause this? ( I *believe* I got this unlock prompt message with lollipop once when t-mobile card was in, but now I'm not 100% certain.. )

I tried resetting this phone, but it didn't help.

I'd like to revert all the changes back, maybe one a time to see if t-mobile sim card will get recognized again. What's the best way to do it? I did all the steps in OP and have lolliipop now. Ran "Downgrade Transfer Package to JellyBean (B148)" which didn't seem to do anything at all. What should I do next and in what order?

I also did this step "10. In TWRP make backup of oeminfo partition - press "Backup" and mark "OEMinfo". Save backup to sdcard.", but I unchecked other options (didn't have enough space on sd card). Hope that's not a problem in case I need to restore this file. And again, if I need to restore this one, do I need to undo something else before I restore it?

Huewei also has "MT2-L03_V100R001C00B148_Firmware_United States_Others_Android 4.3_EMUI 2.0 LITE_05012BPU". Not sure if that's what I need to run now and how different this one from the one in OP (Or should I try the one form OP?)

If it is a hardware issue, will this get fixed under warranty? If so, who do I contact, Huawei or Consumer Cellular (I never had an account with CC)

I purchased this phone a week or two ago, but wonder if unlocking boot loader voids the warranty even for hardware failures?

Thanks.

P.S. Many thanks to OP and everyone else!

Followed the instructions and everything seems to work great. After I installed lollipop I thought I was in a boot loop, as it rebooted 3 or 4 times while the logo was displaying, but then it booted up.

Can someone share APN settings with T-Mobile? (I can copy them from T-Mobile phone, but just in case)
[Huawei Ascend Mate 2] Davinci50:
They are SIM LOCKED you must provide a sim unlock code.
[Huawei Ascend Mate 2] Nikon5400:
How? IF the phone is not promoting to enter the code any longer, how do I enter it?
[Huawei Ascend Mate 2] Davinci50:
Don't know what to tell you I sim unlocked mine as soon as I got them. That was the only way to get it to recognize any other sim besides CC. I used t-mob and Ting.

---------- Post added at 08:25 AM ---------- Previous post was at 08:23 AM ----------

The sim lock is not in the system/ data or bootlader. That is from Shm himself

---------- Post added at 08:25 AM ---------- Previous post was at 08:25 AM ----------

Btw I have six CC phones
[Huawei Ascend Mate 2] Nikon5400:
Right, I understand that. Did you unlock yours before installing lollipop?

I think maybe lollipop has something to do with it and that's why I want to try to downgrade one step a time

ether that or I wonder if there's a way to force that "sp unock" prompt to show up
[Huawei Ascend Mate 2] Nikon5400:
Another interesting thing - when I go to phone-->contacts I still see "Consumer Cellular" in the list. I don't even have CC logo, why is this contact still there?

Update - It also shows under "SIM" group, maybe it got copied over when I inserted CC SIM
[Huawei Ascend Mate 2] Davinci50:
http://bit.ly/1FOY924

Follow the directions attached.

Put the dload file on the sd card and press all three buttons to begin the downgrade process. This WILL erase all your data you have been warned.

This is all I have to offer.

Good Luck
[Huawei Ascend Mate 2] Nikon5400:
Update -

I followed the steps (the best I could) and now it's prompting for "SIM service provider unlock PIN" again.

I had some issues with steps:

after I did the transfer (step 5) the phone rebooted itself and then said something failed. I proceeded with step 7 and once it re-installed the system phone rebooted to boot menu. Unfortunately I pressed power key accidentally and I guess the selected option executed (reboot?)

The phone rebooted and I got my prompt. I don't want to touch it until I enter the unlock PIN.

Question - Now that I think about it.... if we install ROM from an unlocked model, may be that's why phone is no longer prompting for unlock PIN?

By doing downgrading I just did, am I back to stock or not? I assume not and if I still have issues with unlocking I guess I'll need to revert it back to oem stock by restoring OEMINFO I backed up. By the way, OEMINFO was the only thing I backed up. I unchecked 2 other things which were checked by default, because I didn't have space on my 2gb sd card ( and was too lazy to search for larger card). Is OEMINFO all I need to revert back to stock?

Thanks again!

How do I update to lollipop? I successfully did all of this and it's on 148 now, but when I go to system update, it says no update found.
[Huawei Ascend Mate 2] Nikon5400:
I did manual update not over the air.

by the way I'm having no luck getting the unlock code.

it seems like "server 1" doesn't have my IMEI in their database
[Huawei Ascend Mate 2] CTXCI:
Where did you find the manual update lollipop firmware for the MT2-L0T? And here's how I got my code, because I tried for days on their stupid website, calling and emailing US and international tech support, and they all refused to help. I came across a thread online from a long long time ago, and it worked for me, so hopefully it will for you as well.

First of all, don't use the american website. Use the Chinese one.

Go to http://emui.Huawei.com/cn/plugin.php?id=unlock&mod=detail

Input HUAWEI C8812 in the first box.

Input your serial number (on the back of the battery. Not the one under settings) in the second box.

Input your IMEI in the third box.

For the fourth box is where you'll have to download a software. Normally you could dial a code to get the product ID for that box, but it doesn't work for some people with the product ID it gives them.

So, go to http://www.androidxdahost.com/file/1447447369_Huawei_Product_ID_Generator and download and unzip the file to your desktop. Run the software, choose HUAWEI C8812 from the drop down list, input your imei, and it'll give you a Product ID that is generated for your IMEI.

Take that code and enter it into the 4th box on the Huawei site.

Enter the verification code and hit submit, only click submit once, sometimes its slow.

Some Chinese letters show up and then a very long code, that's your unlock code.

I hope this works for your as well (:
[Huawei Ascend Mate 2] Nikon5400:
MT2-L0T? I have 'MT2-L03' or 'MT2L03'

Are you sure you have the same device I do?

This website (first link) wants me to register with Chinese local phone number. How do I get around that?

There's "server 2" which may have an unlock code for me, but they want a non-refundable $8 for the service. So if the code doesn't work (or they pull it out of their axx), I wasted $8 and time.

Here's the link where you can download lollipop- http://consumer.huawei.com/us/support/downloads/index.htm
[Huawei Ascend Mate 2] CTXCI:
Yes sir, I've got the Consumer Cellular version of the Ascend Mate 2 (MT2-L03). The main reason I wanted to go to OEM firmware was for the tethering and hotspot feature that Consumer Cellular was so nice to remove from their crappy version of KitKat that they flash on to it.

And I wouldn't pay for that. Anyone who claims to offer bootloader unlock codes are kind of sketchy. Because bootloader codes can only come from the manufacturer, unlike SIM unlock codes.
[Huawei Ascend Mate 2] Nikon5400:
Oh, I'm looking for SP unlock code, not bootloader. I got my boot loader unlock code from Huawei website and it took seconds.

Good thing you clarified it. I've spent >20 minutes trying to figure out how to navigate huawei website, the slowest one I've ever seen
[Huawei Ascend Mate 2] CTXCI:
Oh! Go through CellUnlocker.net. that's who I used and I got my SP unlock code. They actually send you 4 codes. And they will price match to anyone.
[Huawei Ascend Mate 2] Nikon5400:
they don't list consumer cellular
[Huawei Ascend Mate 2] CTXCI:
Its doesn't have to be listed for networks. Just choose the Huawei section. I had to choose Simlock Block / Subset Unlock Key in the drop down list because my phone was completely sim locked at a corporate level after too many attempts of the wrong unlock codes that consumer cellular gave me. So I gave up on them and went with CellUnlocker. I price matched to sim-unlocker.net. which came to $9.
[Huawei Ascend Mate 2] Davinci50:
[MENTION=4144802]Nikon5400[/MENTION]

You are back to (stock) non- CC phone, which the unlock should work fine for.

Don't try the unlock code more than twice though if it doesn't work, cause it will lock after 3 tries I think, permanently.

Restoring OEM info takes you to stock CC phone but should not be necessary.

@cotylee1991

After you install b322, just put Candy6 on your phone and don't look back.

http://xdaforums.com/showpost.php?p=67173514&postcount=150
[Huawei Ascend Mate 2] CTXCI:
It doesn't lock you out permanently if you enter it wrong more than 3 times.

The phone goes by 4 standards of unlocking: network unlock, subset network unlock, phone unlock, and corporate level unlock codes.

If you enter a network or SP unlock code wrong more than 3 times, it will put it at a corporate level "unlock SIM SERVICE PROVIDER BLOCK", which is the 4th level of lockout.

Most service providers have access to all 4 codes, but most will give a hassle about releasing the codes, especially Consumer Cellular. If you've had the phone continuously on CC service for at least year, they will provide you with the first level of phone unlock. But, that just goes to show that their phones aren't truly unlocked like they claim to be when they leave the store.

That's why I went through CellUnlocker.net. I was sick of the hassle that Consumer Cellular was giving me. So I found sim-unlock.net, which offered the 4 codes at $9, but I'm a very skeptical person and I get bad vibes from poorly made and designed websites, especially ones that aren't secured or encrypted for an online store, which sim-unlock was not, so it drove me away.

I then went to CellUnlocker, who I've went through several times. I chatted with a rep on the online chat, they said they'd price compare it from $24.99 to $9. I placed my order at 5PM and got all 4 codes at roughly 4AM the next morning.

You're never really "truly" locked out of a phone permanently. There's always, ALWAYS, a way around anything. I've been doing this for over 9 years.
[Huawei Ascend Mate 2] Nikon5400:
Consumer Cellular is not on their list,s so contacted them. They said I can pick any provider from the list and told me the cost would be $25. Then I said Consumer Cellular runs on AT&T, they put that in and said $15. I asked if they could try other carriers or match ebay where it's $8 and they said no, the cheapest is $15. So I gave ebay a shot, if I don't get the code, I'll get my money back (although the site ebay takes you to says "Service Policy:We don't accept any video proof for non working codes. This service no refund,no cancellations. ", but I confirmed with seller(s) through ebay, I'll get the money back.

The only downside - the site says 1-4 days, the seller I went with (first one who replied) says up to 8 days. That's ok, I can wait, as long as he doesn't provide me with wrong codes. If it doesn't work out, I"ll try the $15 option.

thanks
