More information about this device:

DIFFERENT VARIANTS AND VERSIONS OF Honor 3C

There are now five main versions of Honor 3C that i am aware of:
H30-U10 (联通2G), H30-T00 (移动1G), H30-T10 (移动2G), H30-L01 (移动4G) and H30-L02 (联通4G).

Most guides and resources provided on this thread are dedicated to Honor 3C 2G H30-U10 with MT6582 chip.
But guides like SD Upgrade and ROM flashing using SPFT might also applicable to other variants with MT6582.
Just make sure you don't mess up and use only files dedicated to your device, please check, and double check.

Since we will be working with Honor 3C H30-U10, let's discuss some known variants of this version.

International set: Comes with LOCKED bootloader. (Ref. Build number: H30-U10 V100R001C900B1XX)
China set: Comes with UNLOCKED bootloader. (Ref. Build number: H30-U10 V100R001CHNC00B1XX)
Europe set: Comes with LOCKED bootloader. (Ref. Build number: H30-U10 V100R001C432B1XX)

Note: International set sometimes referred to as global, MY (Malaysia) or TW (Taiwan) set.

EXTRA: Working With UPDATE.APP - Making it flashable for SP Flash Tool

Part #1 - Converting Huawei UPDATE.APP to SP FlashTool Flashable Files

What's this all about?
* OK, now you know you can apply update using 'UPDATE.APP' by placing it in /sdcard/dload/ folder.
* But do you know there is another way to flash the images directly with computer? Yes there is, by using SP FlashTool.
* This can be quite useful (and dangerous too) as you can skip/bypass the version check enforced by Huawei/OEM.
* Other than that, this method can also be used to install non-official ROM, provided that the ROM is compatible with the device.

Warning:
* Make sure you use UPDATE.APP that was built for your device, in this case, Honor 3C (H30-U10)

For this guide, i will be using update package H30-U10_EMUI_2.3_4.7.16.zip Dev KitKat build (860 MB+) as an example.

1) Download 'Huawei Update Extractor' by @worstenbrood HERE, get the non-setup version. (Don't forget to thank him!)

2) Extract the program files to a new folder named 'HuaweiUpdateExtractor' under 'Honor3C' project dir as shown below.

3) Extract the downloaded update package 'H30-U10_EMUI_*.zip', locate the extracted folder 'dload' and open the folder.

4) Inside 'dload' folder you have 'UPDATE.APP', move the file into 'ROM_UPDATE' folder under 'Honor3C' project dir.

5) Now back to 'HuaweiUpdateExtractor' program folder and launch the program.

6) Set Profile to Unknown, click the browse icon, browse to 'ROM_UPDATE' folder, select 'UPDATE.APP' and click 'Open'.

7) The images list should be loaded as shown below.

8) Right click on any item to bring up the action menu, select 'Extract All' and click on it.

9) Browse to 'Honor3C' project folder, select 'ROM_UPDATE' and press 'OK' button.

10) Wait until the extraction complete, this may take a few minutes...

11) Extraction completed, close the extraction dialog and the main program.

12) Open 'ROM_UPDATE' folder and verify that all images were extracted. (Folder size should be doubled now)

13) Click on '_PrepareFiles.exe' provided in the folder. (Required .NET 2.0+)

14) Now the ROM files are ready to be loaded from SP FlashTool.

Important Tips:
* Please restore your stock recovery before performing the upgrade. (Tips: You can also use the recovery in the update package)
* Official EMUI 3.0 upgrade might fails if you have altered your system, in this case please extract & use SPFT to flash instead.
* Some update package might relock your bootloader and causing a bootloop, in this case please unlock your bootloader again to fix.

OLD GUIDES & ADDITIONAL PATCHES (For References ONLY)

* Upgrading to unofficial ROM - B301 EU Beta / B310 (Offcial for Middle East Countries)

* Upgrading to unofficial ROM - B320 (Offcial for South East Asian Countries)

* Standard Procedures for Installing Unofficial ROM (Now outdated)

P/S: I strongly recommend you to create a Full ROM dump using 'SPFT Readback' before you start flashing to device.
You can also use MTK Droid Root & Tools by rua to dump your current ROM.

restore

if i restore from a backup dump firmware which was the official my firmware, will it auto lock the bootloader too?

Hey, it's nice to see you here, good question you have there!

Well, to answer your question, theoretically yes, but the answer is NO.

Remember that i mentioned in the guide that you CAN'T restore from the SPFT Readback ROM dump if your bootloader is still locked?
The reason behind this is that the SPFT expects you to provide signed images as sources.

Since the dumped images are no longer signed, SPFT will not allow you to flash it, unless the dump was from an unlocked ROM,
Even if you managed to restore the files, you won't be able to boot the device either because the locked BL just won't work with these unsigned images.

BUT, if you are following my guide and use my tool to process the dump file, the output files will be a fully unlocked ROM instead.
The tool will helps you to replace all neccessary files and convert it to a fully unlocked ROM, which you can flash back to device, provided that your BL has been unlocked.

The ONLY known method to relock bootloader is by flashing the B108_Signed images which you can find in OP.

I hope this clarifies some of your doubts, let me know if you have any other question.

If you flashed unofficial EMUI 2.3 KK ROM and applied ModemFix, you will need to flash official ROM (Eg: B115) before returning to the locked ROM.

Yea, my CWM ports are based on International 4.2.2 ROM, so they might not be compatible with China set.
Anyway i have ported another one based on Carliv modified CWM, but using files from KK instead, would you mind to help me test it?
Since we have a working TWRP, the CWM based recoveries will be served as alternatives incase someone still prefer the old school style,
but please be reminded that these CWM ports are outdated and might contains bugs.

Hi, i´m a developer for h30-u10 chinese version, I have a rom based at international updates, named ASAP.
I´m thinking that I can make it for international users undone the port. There is any other problem with modroms like lost imeis?

Hey, nice to see you here! Some of my colleagues already tested your 6pack KK build, and they have good comments about it. :good:
About your question, if international set H3C user flashed emui.com's ROMs, the device will not be able to detect or read the IMEIs,
but the issue can be easily fixed by applying ModemFix provided on this thread. Regarding your ASAP ROM, i am not quite sure,
did you port that using ROM from huaweidevice.com.tw as base? if yes then should be no problem.

Btw, would you mind if i add your ROMs to OP under 'Flashable Custom ROM' section? Nice work btw.

Hi
I am using international version, can i Install MIUI Rom in it after unlocking boot loader and flashing Custom Recovery?
And Custom ROMs are available for this cell or not?

Hi, i am not sure if there is any compatible MIUI ROM available for this device, as we just managed to unlock it.
But for custom ROM, yes, there are many ported from China ROM, you can also check out ROMs ported by @flufytendo.

Just another kind reminder, unlocking the device will void the phone warranty, decide wisely, and always make backup, rom dump, etc.

If you flashed unofficial EMUI 2.3 KK ROM and applied ModemFix, you will need to flash official ROM (Eg: B115) before returning to the locked ROM.

Yea, my CWM ports are based on International 4.2.2 ROM, so they might not be compatible with China set.

For asap I have to fixing the same for China version (is really a c900b1 rom).

I tried your carliv cwm, carliv touch and twrp. The last only can use internal sd for backup and restore so it's a big problem because whenever you install a zip or restore all backups will be lost.
I'm using just now the carliv cwm at Chinese phone, I'll tell you about it . Edit: doesn´t work for intalling zips
For my roms I'd rather links to movilesdualsim, I'm from the staff so is better for our forum. But in the other hand I will do new tutorials for outdoor phones with your work, so as you wish.
one question, where come from the modem.img for fixing kk roms? from jb updates?

edit: kk carliv doesn´t work either for chinese version

I would be happy to test out Carliv mod CWM.

Two of the custom roms on Needrom ask for CWM to install them with. Both failed the install with TWRP even though I was able to boot into one of them. I will let you know how the new recovery works.

UPDATE: I installed the recovery and I could get it to boot up and work fine. I tried to install 2 custom KK roms from Needrom and the install on both of them failed. When I tried to boot into them I got stuck on the Honor splash screen. I will try some other Chinese custom KK roms later and let you know how it goes.

My phone is a 3C H30-U10 Chinese version

Thanks again

We Were looking For you !!

@codelover ,

This is our thread

http://forum.xda-developers.com/showthread.php?t=2773098

we had begun from the time the International Version was released :laugh::good:

Alas we had been waiting for a Legendary Guide Like you !! .

Thanks for the HARD WORK , We H30 - U10 Owners will be trying out the methods u posted,

Simple Questions for You ? ( These were done by Me before you started this thread !)
Story !!---------------
1) when i flashed 4.7.1 ( i was on KK without Signal /IMEi)

2) Then i Restored the NVRAM Restore from MTK DROID , i was able to get a single IMEI for both Devices ,

i used KK and then recieved Chines OTA Updates , and did an OTA Update to 4.7.16

and that was last time my phone ever booted , next the phone restarted and it only kept vibrating

as the Boot Loader was locked, i couldnt do anything !...... Got my phone replaced by Service Centre

------------
Now the Question,

1) if i unlock the bootloader , would i able to relock it ? ( Very important Question )

2) Can we stay on 4.8.1 and keep updating KK as long as HUAWEI keeps giving new UPDATE.APP????

3) Could we get ever get back to B115 ( Pure Stock aka Virgin HUAWEI International)??

4) Would they be able to find out if the phone is unlocked ?

5) Will we get Android L this Decemeber

???

6) What are the Antutu Scores for the MIUI , other KK Roms ?

7 ) ..........To be Continued , My Boss was standing behind me as i typed the prev Question

PLease answer them !!!!

ANSWER THIS MOST IMPORTANT QUESTION !!
Steps planned for today :
1) Full ROM Backup
2) Unlock bootloader
3) Flash KK 4.8.1 using Forced SD Card Upgrade
4) Do a modem Patch if necessary
5) now incase the International ROM gets Official KK

HOW TO GO BACK WITHOUT LOSING IMEI AND HAVING A RELOCKED BOOTLOADER!!!!

Should i Flash B115 First ( Will it give me IMEI) ???

or after B115 should i Flash B108 ( To Get both IMEI & Locked Bootloader) ????????

PLEASE EXPLAIN THIS CLEARLY
