I am new to all this. I dont know how to save the Stock Rom. I have tried to reset my phone via Recovery mode as well as From settings. Nothing works. Please help me.

PS: Ram is near to 350 MB only and Internal memory is near to 150 MB so I cant seem to get any roms of that size.

You can save the ROM with MTKDroidTools software. Google is your friend. And if you save it and send it to me, you will my best friend. : Laugh:
My phone is dead and I want to bring it to life.

Thank you.

Hi I have a iNew i2000 MT6589

I was flashing a stock rom via the flash tool all went ok(I got the green ring)
Went to start it and nothing. I tried to re flash an older Rom but now I get in device manager "unknown device"
I have tried PDA net drivers and tried to install other VCOM but still no go.

I'm running window 7\64.

I forgot I did flash CWM a week ago but I cant get to it. My phone is an i2000.

Hope someone can help

My new N9776 has arrived, and I am trying to make a backup image before I do anything to it. (see previous - I bricked my first N9776 and no ROMs seem to be able to unbrick it). I am using MTK Droid Root & Tools v2.3.4, but when I connect my phone to it, the backup button is greyed out (I cannot click on it).

When I try to root it by clicking the ROOT button in MTK Droid Root & Tools, it tells me to press the restore button on the phone. After I click that, the phone restarts, but then nothing happens. MTK Droid Root & Tools detects the phone after a while, but the Backup button is still greyed out. And it looks like the phone itself is trying to back up my account, but it never gets anywhere.

Am I doing something wrong with the backup process? Any help would be appreciated! Thank you :)

Panda, where a u from?

I'm having the same problem with my n9776. Error 3002.

I tried all the files for MT6628.

Do you backed up your new handset n9776 to try to save the other bricked?

i've seen far too many times that fellow xda member make this same mistake over & over again, including myself...
tongue.gif


So pls pls people, don't use SP Flash Tool to download ROM not meant for your phone, it will brick it & there is no way to revive it back ! After you have download wrong PRELOADER, your phone will be completely dead, cannot power on, no charging, no recovery, no PreLoader USB vcom detection & you can say
rip.jpg
to it...

Here is the WARNING again :

NEVER DOWNLOAD ROM NOT MEANT FOR YOUR PHONE. IT WILL BRICK IT !
----------------------------------------------------------------------

Even with the the WARNING & you still do it...
alamak.gif


Inspired by fellow xda member to start this thread to help out other xda member that run in to similar problem so here are the solution but it might not work for all MT65xx... :fingers-crossed:

If you have already brick it by flashing wrong PRELOADER then you still have a 50/ 50 chance to revive it so keep you fingers-crossed... :fingers-crossed:

For MT6573
Requirement : Your MT6573 factory ROM, SP Flash Tool
MT6573 Meta Driver - If you don't have, download it from here
First you will need to open Device Manager, switch off your phone, press & hold Menu button but don't let go, now plug-in your usb cable will activate META mode(Thanks to Master Shifu Cybermaus for his insight knowledge)...You'll notice Mediatek USB VCOM will appear at Device Manager -> Ports

Mediatek USB VCOM will stay connected until you download factory ROM then it will auto disconnect, reconnect as PRELOADER USB VCOM & continue downloading...

After factory ROM download completed, it will be auto disconnected & you'll have your phone raise from the dead ! :laugh:

This hidden feature will enable you to download factory ROM when you brick it by flashing wrong PRELOADER meant for other phone however for some MT6573 there is no way to access META mode except by dismantling the whole phone... :eek:

If you can't find your model factory ROM, try to hunt for similar ROM. I have had feedback from fellow xda member it actually works ! Luckily, most MT65xx ROM are very similar to each other. Try to look for similarity at build.prop -> ro.build.product for eg, typical build are bird73_gb , e1109_v73_jy1, huaqin73_gb, tinnoes73_s8030_2g, mt73_w831_a9100_yingt & etc... google search is your friend... :good:


For MT6575/ 77
With the battery out, hold the volume up, don't let go & plug in the USB cable will activate META mode for few seconds...Typically, you need to click Download at SP Flash Tool before entering META mode or it will auto disconnected...



If all doesn't work & you don't have a local service center for your MT65xx then may be you would want to try rua1's method but its not for the ordinary user... :fingers-crossed: Use google chrome for translation...

Attach is few photos that i've downloaded from that forum as it can only be viewed by members at that forum.... :good:

Added on Nov 23, 2012 - MT65xx is truly UNBRICKABLE

it seems that MT65xx is really 'unbrickable' thanks to whitetigerdk who inform me with his how-tos :good:

So you can raise your DEAD MT65xx back to life... :D

The trick is quite simple, for whitetigerdk case, he flash his GooPhone Y5 with Zopo100 factory ROM & the phone went DEAD...

He proceed to reinstall preloader driver from Zopo & was able to use FlashTool again and flash back his factory GooPhone ROM & thats how he brought back his MT6575 back to life... :good:

Updates
i've pm'ed whitetigerdk & got a reply from him confirming that indeed his GooPhone Y5 has this META mode built-in (plug in USB while holding VOL +)

Device Manager will detect new device... Having said that, not all MT65xx device has this feature... :eek:
----------------------------------------------------------------------
Added on Dec 20, 2012 - DO NOT USE MEMORY TEST AT SPFT !
There has been confirmed cases that fellow xda member brick their MT6575/ 77 by using the MEMORY TEST function at SP Flash Tool !

When you put a check mark at NAND Flash Test or EMMC Test what it does is that it actually FORMAT it & this will brick your device !

For those who are having problem such as 3013 S_DA_SOC_CHECK_FAIL or 8038 SP FLASH TOOL ERROR for MT6575/ 77 even with testpoint, you will need SP_Flash_Tool_v3.1224.0.sn85
I have upload it to here for ease to fellow xda member, Credits to Master Shifu rua1...

Added on Jan 06, 2013 - DO NOT JUST FLASH ANY ROM WHEN YOU BRICK YOUR DEVICE !
Well known brands like Lenovo, Zopo, ZTE & etc do provide FACTORY ROM at their webpage for download...

However, for those lesser known brand, its hard to say so you will have to hunt for it & do as the title says... :D
Credits to XDA Senior Member cybermaus, he has put up a simple guide on How to search for replacement rom...

It is Master Shifu rua1 that discovered MTK devices can be unbrick via testpoint & he has developed a great tool & continuously updating it, the MTK Droid Root & Tools that can backup Factory ROM out of an unknown MTK devices, get hardware information, Root it, port CWM & many many more...
thumbup_zpse78dc2e0.gif


Its sad to see users are taking advantage of all these free infos & tool developed by Master Shifu... :( Recent check with Master Shifu & he told me he only get 3 donations from xda :eek: Come on people... :rolleyes:

Please understand the significant amount of time and effort required to understand how the MTK devices works, then developing a software, a new function, bug fixes, add new features, testing it & etc before releasing it as a free tool...

Master Shifu never demanded any payment for using his software & inline with the xda spirit to Gives Credit Where Credit is Due you should start hitting the DONATE button now... ;)

As i have mention in this thread before, when you have unbrick your MTK devices using these infos & tool by Master Shifu, it means you don't have to fork out another USD 200+ to get a new devices... :laugh:

So how about spending Master Shifu breakfast, lunch or dinner that you have manage to save $$$ :D
Pls pls consider making a donation to the Master Shifu rua1 to support him to continue development of this free great tool...

I'm having the problem with my n9776. Error 3002 in flash.

I tried all the files for MT6628.

However, the handset n9776 had e1911_v77_gq2000_a41_6628_v20 rom. I downloaded on your page downloads.

I've used other versions of SPFlash.

I used the version of SP MDT Multiflash.

I formatted, I cleared the nvram, the bootloader.

Nothing happens.

Always get this error 3002.

I disassembled the unit and did the testpoint, even detecting mtk usb port.

I need to force the preloader? Please help me!

Hi guys,

I have an Acer AK330s Dual Sim (Chinese version) and i tried to update firmware from an Acer Liquid Gallant Duo (french version) and after update the phone it's bricked. I've tried to reflash the chinese boot img with SP Flash Tool and nothing happens. I've mixed somehow the firmware (boot from chinese version and system.img from french version) and still nothing happened.
Could somebody help me to bring this phone to life?

..i tried meta mode, and tried any combination, but nothing happened..i used to flashed it before with no problem in meta mode, it easily detected..im hoping that the test point will revive my device, but after trying to find the test point still nothing happened, maybe i miss something or any advise..pls help!

Click to collapse

After (stupidly) making a wrong choice while flashing a rom I had exactly the same problem. You write that you tried every combination with your buttons. Well this is what I did.
After flashing a rom my phone went completly dead, no charge led, no connection to pc possible, etc. Then I disassembled the phone and, like you, trying to search the TP. While doing so, I was reading your post and at that moment I didn't know that there was a possibility pushing one or more buttons to try connecting the phone to the pc. So, while my phone was disassembled, I pushed the power button and vol- together, (no battery inside) keep them pushed and connected the phone to the pc for about 10 sec. Nothing happened until I disconnected the phone from the pc, still pushing the buttons. Then by miracle, I heard a sound on the pc. So still pushing the two buttons I re-connected the phone to the pc and then I get into meta-mode and I could flash the right rom.

Mayby I'm very lucky this happend or whatever, but perhaps you can try this. Mayby other people have also this luck, by doing so. That's why I'm sharing this info. I really don't know what the clue is for this, mayby the phone must be disassembled or something else triggert the phone and brought it back to life.......

p.s. I had also no SIM-card and SD-card installed.

    If you can't find your model factory ROM, try to hunt for similar ROM. I have had feedback from fellow xda member it actually works ! Luckily, most MT65xx ROM are very similar to each other. Try to look for similarity at build.prop -> ro.build.product for eg, typical build are bird73_gb , e1109_v73_jy1, huaqin73_gb, tinnoes73_s8030_2g, mt73_w831_a9100_yingt & etc... google search is your friend... :good:


    For MT6575/ 77
    With the battery out, hold the volume up, don't let go & plug in the USB cable will activate META mode for few seconds...Typically, you need to click Download at SP Flash Tool before entering META mode or it will auto disconnected...



    If all doesn't work & you don't have a local service center for your MT65xx then may be you would want to try rua1's method but its not for the ordinary user... :fingers-crossed: Use google chrome for translation...

    Attach is few photos that i've downloaded from that forum as it can only be viewed by members at that forum.... :good:

    Added on Nov 23, 2012 - MT65xx is truly UNBRICKABLE

    it seems that MT65xx is really 'unbrickable' thanks to whitetigerdk who inform me with his how-tos :good:

    So you can raise your DEAD MT65xx back to life... :D

    The trick is quite simple, for whitetigerdk case, he flash his GooPhone Y5 with Zopo100 factory ROM & the phone went DEAD...

    He proceed to reinstall preloader driver from Zopo & was able to use FlashTool again and flash back his factory GooPhone ROM & thats how he brought back his MT6575 back to life... :good:

    Updates
    i've pm'ed whitetigerdk & got a reply from him confirming that indeed his GooPhone Y5 has this META mode built-in (plug in USB while holding VOL +)

    Device Manager will detect new device... Having said that, not all MT65xx device has this feature... :eek:

    Added on Dec 20, 2012 - DO NOT USE MEMORY TEST AT SPFT !
    There has been confirmed cases that fellow xda member brick their MT6575/ 77 by using the MEMORY TEST function at SP Flash Tool !

    When you put a check mark at NAND Flash Test or EMMC Test what it does is that it actually FORMAT it & this will brick your device !

    For those who are having problem such as 3013 S_DA_SOC_CHECK_FAIL or 8038 SP FLASH TOOL ERROR for MT6575/ 77 even with testpoint, you will need SP_Flash_Tool_v3.1224.0.sn85
    I have upload it to here for ease to fellow xda member, Credits to Master Shifu rua1...

    Well known brands like Lenovo, Zopo, ZTE & etc do provide FACTORY ROM at their webpage for download...

    However, for those lesser known brand, its hard to say so you will have to hunt for it & do as the title says... :D

    Normally for most MT65xx, you can't access META mode, to access it on my Lenovo, i have to take out the battery, press & hold volume up(don't let go) & plugin USB cable & the Device Manager will pop-up MTK USB COM for few seconds then disappear...( As the youtube video above ) Only at this MTK USB COM, the factory ROM can be downloaded without PRELOADER, according to Master Shifu cybermaus, thats how they download factory ROM at the first place... :D

    Typically when you have MTK USB COM show up at Device Manager meaning you have factory META mode then you should be able to download your factory ROM with it too... :D No need to dismantle up your phone & look for testpoints... :laugh: Did you press the Download button at SP Flash Tool first then only plugin USB cable... :confused: Or maybe you should try pressing the Volume Up button too while plugging in USB cable... :fingers-crossed:

    Did you try reinstall driver as per whitetigerdk trick... :confused:

    What is the error message you got... :confused: If you can upload then you should be able to download with it too... :fingers-crossed:

    Good Luck... :D

    now how to search for the replacement rom ?
    what things should be matched ?
    Click to expand...
    Click to collapse
    Hard to say. Best thing should be a ROM that you simply *know* is for your exact hardware. Someone who clearly has the identical phone, and vouches for a working ROM. Or from your vendor.

    Failing that, I would look for:
    - same processor
    - same memory specs
    - same buttons and number of buttons
    - same sensors
    - same screen resolution
    - same display type (IPS vs LCD vs OLED)
    - same camera resolution
    - release to market at about the same time

    Not so critical is
    - screen size
    - battery size
    - physical size

    And luck. You need luck. But as mentioned, you can invite luck by only flashing boot/system/cache/user when doing so, it means you can always go back.

    I am still trying to see if it is worth trying to port the A750 for you, as it has all the above hardware the same. Can you for me also collect this info:

    Start Droid tool. Choose ADB terminal. Type the following in the command window:
    Code: 
    adb shell (enter)
su (enter)
ls /sys/devices/platform (enter)
ls /sys/bus/i2c/drivers (enter)
cat /proc/devices
    I want to see if they are similar to my A750.

    As to your IMEI and SIM: Since your phone is originally a single SIM phone with the second one hidden, I would expect an original ROM to only know about 1 SIM. Do you need dual SIM? Also, I think I would like to hande the IMEI problem only after you have a ROM. You probably just need to rebuild your NVRAM, so even if you have a correct ROM, it will not have IMEI. Lets handle the hardware first, the IMEI later.

    alamak_zps2e31ed77.gif


    Pray hard its the same ROM for your device... :eek:
    -------------------------------------------------------------------------------------------------------------
    As for the rest of the guys here...
    There is no one to blame except yourself for not googling more info before you start modding this & that... :cowboy:

    Many has pm me & i can't help b'cos i don't have your Factory ROM as simple as that... :angel:

    My final advice to those that cannot find your Factory ROM is that you forget about the whole unbricking process here & get yourself a new device...
    ag_zps1e5a29ec.gif


    MT6589 are super cheap nowadays... Having said that, pls get a branded MTK device where you can get the Factory ROM from their web-page... :cool:

    if you intent to stick to cheap MTK devices then make sure you backup your Factory ROM using Master Shifu rua1's MTK Droid Root & Tools the moment you got your device... :cool:

    Cheers... :laugh:
