there's another tool called SPMultiPortFlashDownload it looks like this

Only problem is that it only flashes stock roms that have this format:[Only registered and activated users can see links Click here to register]

If you have any roms that look like the pic above, extract them, open the tool and under Scatter File, select the scatter file present in the stock rom you extracted..Make sure the Data Source file and DA file name point to their respective files as shown in the pic(don't touch any other options). Remove your battery and connect phone(without battery) , click Start All and then connect your battery..it will start flashing..

now about that alcatel driver, i don't think it matters alot but try the above tutorial and we will see

Have you tried it your self?

thanks for that.....that format is unzipped Official ROM suitable for flashtools.
I notice you used the word stock.....while I use the word Official but if the format is that format.....then a custom ROM could be tried.

Once OP gets it to work, he can then re-root the phone and put a decent CWM or CTR on it and he is good to go

yes i have tried it many times..but on my Cubot gt99..Stock rom is same as official and i am not sure that many custom roms come with scatter file but if you find any then you can try. I prefer using the official roms because they dictate the exact size of the memory partitions..

When you connect you phone without the battery via usb then connect the battery, windows should show you a driver in Device Manager that then disappears after about 3 seconds..make sure that the driver is not unknown but a MediaTek usb VCOM..

wonderful

Maybe you can write up a tutorial I am sure lots of people will love it.
Did you originally associate the PDA Windows USB driver or something else?

Hello. Thanks for replying. I tried out the SP MUlti-port sw but doesn't seem to recognise the scatter file for mt 6592 i give it. The same scatter file is readable from the SP flash tools v.5.1348. Maybe it is not compatible with systems with the MT 6592 SOC. But i might be wrong

---

Apart from that windows always shows "Alcatel single RNDIS interface #2" and no MediaTek usb VCOM.

---

Keep in mind that with sp flash tools i have formatted whole mmc of the phone and that might be the reason the sp flash tools don't see the phone any more

Thanks for advice. The device manager now shows under 'Network adapters' : " Android USB Ethernet/RNDIS #2" (with an exclamation mark at the beggining) which is lost every aproximately 30 seconds (for about 10 seconds) and then reappear and all this loop again and again. However, in this situation, i tried out the sp flash tools and do not work (maybe as expected!)

---

Does the MediaTek Vcom driver presupposes the existence on bootloader installed inside the eemc of the phone? As i explained before sometime i "format whole mmc" of the phone yesterday.

---

Good news. I made a step front. I removed the Alcatel driver, installed the drivers you gave me, i see now MediaTek USB Port (COM21) i successfully did a "Format whole flash except Bootloader". Additionally i did a MemoryTest and i got: Internal RAM 128KB, External RAM 1024MB, NAND Flash: "ERROR: NAND Flash was not detected!", EMMC -- all sizes correct -- , Data Bus Test: ..... OK!!, Address Bus Test ... OK!!. But when i try "Download" with option "Download Only" and only "RECOVERY" checked i get a message "BROM ERROR: S_NOT_ENOUGH_STORAGE_SPACE (1011)"

---

Now i went back to device manager and i see under 'Ports (COM & LPT)' : "DA USB VCOM Port (COM20)"

---

Notice that my phone has 1GB RAM and 4GB ROM.

Guys

I interrrupt in the hope info is useful.

How certain are you that you wiped your entire flash media? Can you advise what method you used?

2) Apparently Windows users, I am not one, can sometimes trick their USB driver by using USBDeview?

3) If you have flashed your preloader and you have downloaded the Official or stock full ROM and unpacked it,
with the correct scatter file.....you may be able to re-flash ......by ticking only the preloader box......the preloader

then trying to flash your recovery......but I would be tempted to put a custom recovery but I don't know enough about Windows flashtools to say that with any certainity.

good luck

I suppose that flashtools is the only tool which can flash chinese phones. I haven't seen any similar tool running on linux. Believe me i never wanted to get involved with windows but i don't see any alternative. At least the flash tools have been based on QT tools... anyway. The point is that i 've stuck on the point that when i download any portion of a stock ROM i always come across to the message "BROM ERROR: S_NOT_ENOUGH_STORAGE_SPACE (1011)" and this is it. From inside3 flashtools i can only successfully format the flash memory or doing memory tests.

have you tried an older version of flashtools? like the v3.
