A while ago I made a post about how I hardbricked my Wiko Lenny, and I finally decided to try the testpoint method. The problem is that I have absolutely no idea as to where that testpoint is on the PCB.
Can someone guide me? I attached some pictures with the PCB.
Okay, I found the testpoint. It's noted as KCOL0, and it's under the PCB, near the volume up button. I connected GND with KCOL0, but the phone is rapidly switching on and off. I can't flash it in this state.
After a few minutes of constant switching on and off, the phone decided to calm down and let the PC detect it.
In Device Manager it appears as "USB Serial Device (COM6)", and SP Flash Tools v5 detects it easily. But it can't flash it. It always spits out this: "S_FT_ENABLE_DRAM_FAIL" and stops.
Any ideas?
Come on, guys... Someone here must have at least a bit of experience with Mediatek phones...
Please tell me your status for now, also tell me how you got into this ??
I mean how you made a brick??
My phone has the habit of simply going into a bootloop once every few months. I always repair it by reflashing the ROM in SP Flash Tool, but last time I used a tool supplied by Wiko. Apparently the tool reflashed the entire phone instead of the Android partition, and managed to corrupt the preloader. As a result, the phone didn't turn on, vibrate, or even get recognized by the PC.
A while ago I made a post about this, but nobody wanted to help me. I researched the internet and found out that the phone can be repaired by META mode, by JTAG or by testpoint. META mode isn't available on MT6572 devices, so that didn't work. JTAG seems too complicated for me, so the last option was shortcircuiting the KCOL0 testpoint.
I opened up the phone's back, took the PCB out and soldered a copper wire that connected the groundpoint(GND) with the testpoint(KCOL0). After connecting it to the computer, the phone started turning off and on rapidly for around 10 minutes, then decided to stop, letting it be recognized by the PC. It appeared as "USB Serial Device", but it should be called "Mediatek MTK PRELOADER" or something similar. I thought it was the PC, so I continued.
Started SPFT, loaded a scatter that I backed up from the last flash, then clicked Download. After 30 seconds it stops and writes this: "BROM ERROR: S_FT_ENABLE_DRAM_FAIL (4032)". Tried resoldering and reflashing, but same result.
Any ideas?

Error 4032
Message: BROM ERROR : S_FT_ENABLE_DRAM_FAIL (4032) [EMI] Enable DRAM fail
Meaning: The firmware you're trying to flash is either not compatible with your device or you have selected the wrong flashing settings
Solution:
* Ensure that the file(s) you're trying to flash are actually for your exact phone model
* Ensure you tick the boxes for only the files present in the ROM you're about to flash
* Probably have the wrong driver installed. Uninstall vcom, preloader and MTK drivers using usb deview then manually re-install using forum.hovatek.com/thread-440.html
* Delete the sp flash tool folder then re-extract
* Ensure the phone is switched off (with battery still inside) before connecting to PC for flashing.
* If that doesn't work, keep holding down the volume decrease button just before connecting the phone to PC for flashing (you could try volume increase , power + volume decrease or power + volume increase).
* Consider using the latest version of Sp Flash tool
* Format the phone before trying to flash the file(s) again

Sorry for my English.
I have one with the same "dead".
Make short between Kcolo point and GND.
Be sure battery is full.
Use V20 firmware.
Select firmware up-grade from Smart Phone Flash Tools.
Connect phone to PC with Volume + push
Don't forget to remove the jumper after flash

I still didn't manage to repair it, as I may have made a mistake while soldering and shortcircuited the phone.
I may try again, though.
I have the same issue but my Wiko Lenny 3 is dead for a while (like 2-4 years). Until this time, I was trying to repair my device, but no luck occurred. But I can't find the KCOLO point, as I should. It is either on the main board / motherboard (I don't know how to call it) or under it. I'm of a smartphone repair noob...
I hope that I can finally manage to repair this device because I don't know what I should do with this device.
And added the image to see if you guys can find the KCOLO / KOLO / COLO point...

Hi all,
I have a Star/Bluebo B6000 phone which I believe is based on the MediaTek 6589T.
I followed the procedure here: http://forum.xda-developers.com/showthread.php?t=2206421
to set up a new ROM for the phone.
I seemed to have gotten it all done properly, but the phone only stays connected for about 2 seconds. The SP Flash tool moves into the red progress bar and then just fails.
Luckily, there isn't any software damage on the phone (from the look of it).
I'm trying to put in a new ROM to actually fix a previous issue where my phone remains on but when I press the home button or the power button the screen stays blank. Think a new ROM/fresh start may solve this.
But the core issue is that I am unable to put in a new ROM because the phone doesn't remain connected long enough.
Is there a solution to this? Or is there another way to install ROMS?
Thanks.
There are several things the issue could be.
Try running SP Flash Tools as Admin.
Try a different USB cable.
Try uninstalling current drivers and using PDANet VCOM USB drivers
Try a different PC
Try MTK Flash Tool as opposed to SP Flash Tool.
Make sure the scatter is correct. Create a new scatter with MTK Droid Tools
None of them work.
I've tried 4 different cables. MTK and SP tools.
It seems as though something is wrong with my preloader. When I try to 'restore factory settings' or even try to restart in recovery mode, the phone doesn't do anything. It's almost as though these modes don't exist or are bugged/busted.
EDIT: Yes, it seems to be some kind of preloader issue. When the phone is OFF, I connect the USB (which the computer recognises) and the within 2 seconds the 'disconnect' sound comes up. Within 2 seconds after that the battery charging shows up on the phone.
I say this because when the phone is ON, I am able to transfer files onto the phone and treat the phone as a normal connection. Something within the phone's software is causing SP Tools/MTK Tools/Other drivers not connect to it. I have a feeling I may have a corrupt/broken preloader/recovery system.
Thanks for the help. Please do advise as to what I can do.
Anyone?
Really could use some help.

On my phone, mine has the same chip as yours, to flash in preloader mode, I do it in this order,
1 connect phone to pc via usb with battery removed,
2 load flashtool with scatterfile and rom to flash,
3 click on download in flashtool,
4 put battery into phone
SPflashtool then searches for the preloader driver, loads it briefly and then loads the DA Usb Vcom port driver and then proceeds with flashing
This will only work if you have the usb vcom preloader drivers installed on your pc
To check if you have preloader driver installed, open device manager on your pc, connect your phone with usb cable and battery removed, put in battery while watching device manager, if driver is installed you should see 'Preloader Usb Vcom port' appear in the ports section,
but it will only be there for a few seconds, and will dissappear again. If you do not see this you need to install the Vcom driver.
Hope this helps

Do you see the preloader driver in device manager when you connect your phone as I described above?
Which build of SPflashtool are you using? the tool is quite buggy and sometimes helps to try another version

any One what i can do now ??!!!
Help for god sake !!
Ok, i think the only way your going to unbrick your phone is to flash the exact correct rom for it, Do you have a copy of the stock rom for your phone suitable for SPflashtool?
The link that you show is for a Feiteng H9500, that is very unlikely that it will work on your phone, the reason your phone is bricked is because you have probably flashed the wrong preloader block, and that is whats causing the trouble, you need to make sure you have the correct rom for your device before you start.
I think the only time you had a little success is when you accidentally entered preloader mode and if it were my phone I would concentrate on getting the preloader driver installed. There are some tutorials on here to install the drivers, it can be a bit tricky, and not all mediatek devices are the same, so a bit of trial and error may be needed
Once you have the Preloader usb vcom drivers installed I would then attempt to flash just the preloader and dsp_bl blocks initially from the correct rom for your phone, and then if successful flash the remainder of the rom, without preloader and dsp_bl
If you flash the wrong preloader/dsp_bl you will almost certainly brick your phone, so it must be either from a backup you have made of your original rom or from the exact stock rom for your phone.

So the preloader vcom driver is installed ok on your pc, but you do not see it when you connect your phone, maybe you need to connect in a different way, on my phone I have to connect switched off phone with the battery removed, and when the battery is put in, then you see preloader driver pop up in device manager, there are many different MTK phones and different ways to connect.
The stock rom you have should be fine as long as it is the correct one for your device.

If your phone now is completely dead, probably your only hope of reviving it is by using the test point, see 'Modes of the virtual COM ports', here.....
http://forum.xda-developers.com/showpost.php?p=38369102&postcount=11
Ive never done this procedure, so cant help much with it, but if you search these threads for mediatek test point or similar, you might find some info on it

As I said, Ive never done this myself, only read about it and have no idea where the test point is on your phone, they all appear to be in different places, on an mt6577 I had previously it was easy to find, just by the sim slot, there was no need to even strip the phone down, but on most other models they all seem to be less accessible. It will be somewhere on the main board I would imagine, usually, but not always, a small round brass dot about 2mm accross, and I noticed while searching that some are marked 'KCOLO' or similar. I believe also from what I've read that the manufacturers use this method to input the factory rom, so it must be there somewhere, its just a question of locating it. The best method to find it apparently is by testing different points with a multimeter to find one that corresponds with your battery output.

and a link to rua1's russian thread on the subject, translation with google chrome is not very good but there are some pics throughout the thread that might be helpful.... http://forum.china-iphone.ru/test-pointi-dlya-proshivki-preloader-na-mt6573-75-77-t22559.html
Lately during the morning after having my P9000 charged overnight it suddenly shut down and after that was completely unresponsive:
I tried powering it back on but it wouldn't (neither by pressing the power button nor in combination with volume+ or any other button).
I tried charging it again but the LED isn't lighting up so I'm guessing it's not actually charging either.
Then I tried to reanimate it with SPFT but realized that the phone wasn't recognized by the pc. When I pressed the volume+ button it was recognized as "MediaTek USB Port (COM3)" for some seconds but then disappeared again.
Despite of that I tried to flash the stock ROM 20160810 (as well as others - no difference). Every time I get the same error:
BROM ERROR: STATUS_DA_HASH_MISMATCH (-1073283068)
Also I tried to flash preloader only, without any difference.
Then I opened the cover, removed the battery and tried again - nothing changed: The pc recognizes my phone only when I'm pressing volume+ but throws the error above when trying to flash.
Next I shortened the GND point on the phone's mainboard to any test points, but couldn't bring the pc to recognize the phone.
Any ideas...? Does someone know what the error message means? I know that DA stands for "download agent".
You haven’t said much about as to what you had done with this phone prior to your issue, whether you have left your P9000 as standard with OTA updates or perhaps you have rooted, flashed a different Rom or changed its Kernel ?
It’s hard for anyone to give help easily without some background from you.
You're right, I bought it two weeks ago as a used part. To my knowledge it was left as standard (previous owner didn't seem to be skilled too much since some of his folders remained on the phone) and as far as I remember the installed ROM was 20160810, although I'm not 100% sure since I'm also new to android / not experienced with ROM versions and didn't write it down. At the end I believe the phone had never been rooted or changed kernel.
Maybe worth mentioning: The last two days before failure I noticed that the phone restarted one or two times per day.
@brager
There are two possibilities (or more)
1. It's hard bricked, so Google for a mtk hard unbrick guide
2. It's a battery related problem
Keep it two days plugged, or replace it
Keep in mind that the newest mtk software has to be installed on your computer
And try another cable first of all

I think the phone has a hardware problem and went to heaven.
Brom error: Status_da_hash_mismatch
brager said:
Lately during the morning after having my P9000 charged overnight it suddenly shut down and after that was completely unresponsive:
I tried powering it back on but it wouldn't (neither by pressing the power button nor in combination with volume+ or any other button).
I tried charging it again but the LED isn't lighting up so I'm guessing it's not actually charging either.
Then I tried to reanimate it with SPFT but realized that the phone wasn't recognized by the pc. When I pressed the volume+ button it was recognized as "MediaTek USB Port (COM3)" for some seconds but then disappeared again.
Despite of that I tried to flash the stock ROM 20160810 (as well as others - no difference). Every time I get the same error:
BROM ERROR: STATUS_DA_HASH_MISMATCH (-1073283068)
Also I tried to flash preloader only, without any difference.
Then I opened the cover, removed the battery and tried again - nothing changed: The pc recognizes my phone only when I'm pressing volume+ but throws the error above when trying to flash.
Next I shortened the GND point on the phone's mainboard to any test points, but couldn't bring the pc to recognize the phone.
Any ideas...? Does someone know what the error message means? I know that DA stands for "download agent".

Hello
I had the same problem, (error BROM ERROR: STATUS_DA_HASH_MISMATCH)
what I did: I use Windows 7 System
1- clear all drivers for smartphones with "usbdeview-2-17"
2- install Drivers "Drivers_Auto_Installer_v1.1236.00"
3- install "PdaNetA4170"
4- use "SP_Flash_Tool_v5.1708_Win" to flash the rom. first flash the preloader alone and then flash the others.
the problem was the bad installation of the drivers, after that everything went well for me.
try it can work for you too.
the mentioned software is easy to find on google

Hi, i bought power 2, phone not open and noting happen when press power or vol+ - together + power, or ....try everything
Bricked when try flash twrp recovery. later i try flash rom again, my computer see phone when phone is closed. can not open already. But now my computer not see the phone:A request for the USB device descriptor failed.
What can i do, and sorry for my english
This phone can't be bricked (mostly). You can easily restore the stock firmware, just download stock rom from official site, extract it. And use sp flash tool not the one that comes with the official rom. Open sp flash tool.
Load scatter file from official rom, you can leave the DA file for all mtk phones that comes with stock rom or use the one in sp flash tool (just leave it as it is) in the user interface of sp flash tool.
Make sure it says "download only" from the drop box. Click download then connect the phone to your computer. Flashing will start and should take about 1 minute and 30 seconds to finish.
If flashing doesn't start. Make sure you have vcom drivers installed. (Also for flashing to start, phone must be turned off obviously, but since you have semi brick, you don't have to worry about that).

Go to developer mode menu (if you don't have it, tap on "build number" in "about phone" from settings, seven times and it will be activated). Then change how your USB acts when connected with computer.
If you can't, just use ES File explorer to send files between your computer and phone in FTP or SMB mode over WiFi.
Have the same problam.
The pc recognize the vcom device but only for 2-3 secconds and then disaper, then i get an error with sp flashtool.
Phone isnt tured on. At all.

I do not know if it is late. I had the same problem with another phone. I was solved as follows:
1. Unplug the usb cable from the computer
2. Power off the phone
3. Press download on sp flash tool
4. Holding vol+ and power, plug the usb cable on the computer.
Hi,
can anyone provide me with nvram /nvdata backup please of Ulephone power 2?
I have probably correct IMEI, valid MAC fo Wifi/BT ...
It looks like my serial number changed to 123456789ABCDEF and I have no idea how to change it to original because MAUI (?) stucked on get kernel
I can find original box with correct serial and IMEis on stick
The only one problem with mobile is I am not able connect to mobile network - registration SIM to mobile network always fail.
and at MTK engineer I have only Bluetooth, FM Receiver, Wifi, Wifi CTIA, Wifi Display
I have nothing like Radio, CDS etc ...
OEM unlocked, TWRP, rooted
Some information probably lost when flashing
And of course another problem :
except GPS and proximity, all sensors does not work - G sensor, acceleration, magnetic sensor, compass . Probably configuration data is located at nvdata
i tried flash 5MB file nvdata.bin from different MTK 675x device, but nothings change
I tried flash 33 MB nvdata.img from same MTK 675x device, but I lost IMEI and nothing solved
This is why I need 33 MB NVDATA.IMG from another functional Ulephone power 2
I can change IMEI at MTK then ...
I had to flash , because phone was unusable - it stucked mostly on obtaining IP address wifi
after a while, phone disconnected from wifi and cant find any wifi or if find, then cant connect because of some security issue , after restart all was OK ...
Thanks
Hello.
Everything has gone terribly wrong for my phone and I desperately need your help.
I downloaded what was stated on needrom.com I made sure MTK vcom was installed properly and had the correct rom from needrom.com but I still got Brom Error: STATUS_BROM_CMD_SEND_DA_FAIL in SP flash when using MTK_AllInOne_da.bin.
I then tried DA_PL.bin and got another error. I tried to uncheck preloader and run Download through SP flash with DA_PL.bin which worked just fine. However now I'm stuck at the Bluboo logo screen and phone does not load into android.
I still get Brom Error: STATUS_BROM_CMD_SEND_DA_FAIL in SP Flash if I use MTK_AllInOne_da.bin but if I use DA_PL.bin now I get this error:
Chip mismatch!
Scatter:MT6757D
device: MT6757
Please help me, my phone is bricked until one of you help me. I'd be forever grateful!

Don`t worry about that, first this is the link of the last update https://www.google.com/url?q=https:...ds-cse&usg=AFQjCNFJKeEcDClPU2MnxLJefaQ19GmQpQ
for more success put your folder of SPFlash Tool near to folder of your unpacked rom (for short transmission of data) and Bluboo S1 has a few different way to enter to other mtk cause battery it`s not removable like other just disconnect it and connect again; in this case connect cable usb to your device, prepare all the files in SPFlashTool and click download and now while pressing both volume + and - connect cord to pc till SPFlashTool begin to recognize files (red letters) and release now, SPFlashTool continues process till 100% in yellow progressing line

Thanks!!! It works!!!!
Just be very careful. The USB C connector port in the phone is very loose... so make sure you can hold the cable tight other wiser it will lose the connection and brick your phone. For me, I had to remove the Plastic cover to be able to hold the power cable tight!
Hi, could you help me please? I did your steps, but it is not working. Sp flash does all its job, shows the green sign, but the phone stills dead. What I noticed the usb connects with the phone, then it disconnects. I tried to install the drivers as the tutorials say like deactivating the driver signature enforcement, but nothig happens well.
