[Q] Huawei Honor 3C hard-bricked ?

Hi all,
I just like to share a problem and I need your advice.
I have a Huawei Honor 3C and wanted to upgrade to Android 4.4 Kitkat. I wanted to unlock the bootloader. I used SPFlashtool but forgot to remove the battery and an error occurred. The phone went out and never started after this. When I try attempting to restart, no sign of the phone. I tried all possible ways (volume + and power, volume - and power, ...) but nothing worked. I put it in charge to hope for a sign of life, but only a continuous vibration appears when charging and the screen remained desperately dark. :crying:
Is my phone dead? Is this a hard-brick? Is there a way to fix it?
Thank you in advance for any help or suggestions.

i think that if you brick you phone flashing you must have mediatek drivers, so i will skip this part, i cant post link here cause im new so i will send you metod for mp.
you must have an stock rom in dload folder in sd. if you have original version(which you device brought is much better.

Read carefully this thread, I think you will find solution (if you haven't found yet) good luck

I am also having same problem. no solution yet. all options tried in spflash tools still having "Obtain DRAM failed" error. any suggestion.

Most huawei devices (hard bricked) and show BROM error using spftools try this software by huawei.

Change Wifi , BT , IMEI , Serial Number of any mtk android phone .

Intro : Hello guys i had used SP flash tool to flash stock rom on my micromax canvas a1 . After That i selected Format and Download ( normally we just download but i selected format and download ) and found flashed the rom . Now i noticed the serial number of the device was turned to 00000000 and imei number to invalid . So now i fixed the invalid IMEI number problem . ANd i am back with a tutorial on how to regain serial number back of you phone to regain warranty .
CHECK THIS VIDEO BEFORE MOVING FURTHER -
To check Serial Number just connect your phone to PC ( usb debugging ) and type adb devices ( correct adb files needed )
You can also use Uncle mobile tool -> Device Information to check the serial number
Using Different serial code for infinite warranty is not a good idea as there is serial code printed behind the phone. and its illeagal .
Note : This post is for educational purpose only . Here i will be teaching you how to regain serial number to the one which is on your device box ( u should not change serial number to something else ) Customer service refuse to help me with a wrong serial code so i found out how to regain old serial number .
ROOT + NON ROOT METHOD :Step 1. Download and Extract the package given below .
Step 2. Run IMEI and SN writer .exe file .
Step 3. Download the DB as well as GLU files for your mobile.
Step 4. In IMEI and SN writer Select USB and then smart phone
Step 5. Click on 'Select DB' and attach GLU file over there , Later on attach DB file ( once you double click on GLU file the popup wont go , U again need to select the DB file )
Step 6. Now Select Serial Number , IMEI , Bluetooth , Wifi mac adress in write item and write what numbers and values you want.
Step 7. Click on start and turn your phone off.
Step 8. Connect your phone in Switched off mode and wait till it flashes and done. You have changed BT WIFI IMEI and SN number.

Hi, can I use this method and tool to fix SN on Leovo P70-a phone, I have fixed IMEI1/2 problem after flashing stock rom with sp tool but cant find a way to fix serial number SN:null PN:null. I have APDB_MT6752_S01_KK2.MP13_ and BPLGUInfoCustomAppSrcP_MT6752_S00_MOLY_LR9_W1423_MD_LWTG_MP_V1_P67_1_lwg_n files that came with stock rom.

Hi, I did like you (format&download) with my tablet Lenovo Tab2 A7-10F and lost Serial Number, as well as the Wifi mac address (it changed every reboot). It's the mediatek MT8127. Where can I find APDB and BPLGUI also other stuffs (meta modem?) to write back the SN and PN?. If it's in the stock rom, which file should I take? Many thanks for your help, I'm newbie

Doubt
Hello. I am beginner and I need a help from you. I am trying to follow this procedure, but I'm having trouble with the GLU and DB files. I read that the GLU file is within the Imei fix package, but how do I know which file is compatible with Galaxty S3? The DB is also in this file? Thanks.

this is the permanent fix for imei

can I write old logical board info on a new one(S/N,IMEI...)
Hello all,
I would like to buy a new logical board for my N910c but I have a few question before, if any of u know to answer me.
I would buy it as new OEM because old one isn't fully functionally (missing blitz camera + sensor, lose wifi signal or is low, 4G)
1. when logical board come to me will be without Sistem, IMEI,S/N... ?
2. can I write old logical board info on this one. S/N, IMEI...
2.1 This can be done more easy and right in a Samsung authorized service and
phone will have no problem in future?
3. If the answer for this is yes come another question, if my KNOX will be untouched 0.
3.1. new system update will come as normally?
Reason I want to do by myself is price. I found is more cheap to buy same logical board. Samsung authorized service give me logical board with almost +10%.
I need this info on new one to make my identification with some device from work.
Thank you for your time.

As he says it is written on device back and service center operators can check it there

Meta mode error is displayed
By using this method i can't fix my imei number and serial number error . because when my mobile enter into meta mode after few time its give an error like this "Meta Mode error"
Help me for this problem.. Thank u

Hello , i have found a solution to fix imei issue which is much simpler than sn writer tool. This method works for rooted devices.
All you need is an android device which is rooted(use kingroot as it works flawlessly on android 4.2.2 and above)
after your device is rooted download Chamelopon apk from playstore or from xda itself.
Open the app and click on insert imei, write your imei and reboot your device....and there you have your IMEI fixed. Ive tried many tools but this works flawlessly and saves a lot of time.
Hope you find this helpful.....CHEERS

talvigi said:
Hay, there, Thanks for the post, I was glade that in 2015 someone there also thinks for old guys too, because i have seen most of the post for MTK are before 2015 and inactive,
So my question regarding this is that, is this fix is the permanent solution for NVRAM ERROR (Which causes invalid IMEI, Wifi mac address changing, S No and i don't know what it does to the Bluetooth) AND The GLU file you gave does not have the MT6572 does it support my wiko Lenny MTK6572
AND BTW where can i get DB & GLU for my Wiko Lenny Mediatek MT6572, Dual-core 1.3 GHz Cortex-A7 (I really don't have them and couldn't find them from uncle google yet, meanwhile i have downloaded an update file from wikomobile.com/UK and have an SPFlashtool flashable ROM but it also doesn't have the NVRAM as far as I can see. You guys are devs you may also now some ways to extract NVRAM for system.ext4 or somewhere)
And Finally whether i can copy paste my current NVRAM folder (while i know the error is there because i have made this backup after i got the NVRAM WARNING Error 0x10)
Please HELP because i think my questions are quit relevant to the job and the fix you kindly provided to the sanking guys.
Thanks again

Hey, almost 6 months ago i lost my IMEI/Serial No. i tried everything and nothing worked for me. Maui META is useless. i think it doesn't connect to phone because of the new MT67** series of Chipsets. So in the end i got my IMEI back by rooting my phone.
if you have a rooted phone. I will tell you the Process if you want

its ok, i understand now. but sorry, there's nothing that you can do if your bootloader is locked, and you cant boot up to enable oem unlock. all you can do is try to get a rma.

Put the device in fastboot and Use old MI Unlock tool and see if if it unlocks the bootloader. Post that you can flash the fastboot rom.

Read the above links again. Unfortunately they're all in English, so you may need to use Google translate to understand them fully.
You will need to open the phone to set it in EDL mode.
You will need to contact someone in Russia that has an authorised service account and pay him about €20
He will then need you to allow him to control your PC by remote desktop to flash your phone and unlock the bootloader.
All the information is in the above posts, including the contact details for the Russian guy. There have been a few people that have done this, so this works and the Russian guy is reliable.
There is no physical reason that this cannot be done by the Italian service centre. Maybe you could try to ask them again if they can take pity on you and help.

You're not supposed to relock the bootloader with anything other than the original software, even different regions of MIUI for example. Otherwise the device bricks itself.
