Summarizing my experience with the bricked X626 (so far)

Okay, so after a few days of messing around with the x626 - I was still unable to get it fixed :crying:. However, since I spent quite a few hours tinkering with the flashing process, I figured I might as well document my experience on XDA so other people who are having the same issues can at least get to where I am without having to waste a few days messing around with their PC, and perhaps share their experience with the rest of the community once they are able to unbrick their x626!

Resolving USB connect/disconnect issue (Windows 10)

-------------------------------------------------------------------

This was finally resolved for me - and I found the following solution to work most of the time:

1) Restarted PC in troubleshooting mode

2) press "7" at startup screen option to enable the user to install unsigned drivers.

3) After the booting is completed, open device manager

4) Connect the x626 to the PC's USB, wait for the generic USB driver to show up under "Ports (COM & LPT)" (along with the USB connect chime sound). Sometimes, you have to wait for a minute or two for this to happen. If this doesn't work try holding the power button and Vol -, it 'wakes' up the phone somehow.

5) Once you see the new COM port lights up on Device Manager, quickly select it, right click, update driver and overwrite with the "MediaTek DA USB VCOM" from the Windows+10_MTK+VCOM+USB+Preloader+Drivers inf file (you'll have to google the instructions from other website but it's pretty straight forward).

6) After this, disconnect the x626 from the PC's USB port and reconnect again. The PC will most likely try to switch to another COM Port and reinstall another generic USB driver. If it does that, repeat step 5 and overwrite the new generic driver and COM port with the MediaTek DA USB VCOM driver . Keep doing this until you end up with a situation where you have the PC cycling between 2-3 COM ports in the connect/disconnect loop but at least they will be showing MediaTek DA USB VCOM every time.

7) Now reassign all these COM ports (right click, properties, Port setting, advanced) to a single designated port (like, say "3").

8) If you follow this instruction, the phone will still connect and disconnect from the USB, but each time it does so the phone will always connect to the same COM port and using the same driver - this will make it much easier to flash.

Resolving Flashing issue

------------------------------

This may not work for everyone, but this is what worked for me:

1) Power down the phone first (by holding Power button and Vol - button for 15 seconds since I have no way of telling if the phone is on or not due to the constant black screen) ,

2) Keep holding the Vol - button and plug the USB cable in, wait for the connection sound to chime on my PC

3) When that happens immediately click on Download button on Flashtool. Timing is crucial here, you have to be pretty quick with steps 2 and 3.

By doing this I was able to get the flashing going most of the time - though I do still get the "BROM ERROR : S_COM_PORT_OPEN_FAIL (0x3F5)" every now and then in which case I would unplug the phone from the USB and try again.

Dead end?

------------

Unfortunately, I wasn't quite able to flash everything. If I try to flash all the items in the Download table (except recovery and boot) using the Android scatter file, authentication file and DA_PL_HIGH.bin file per instruction, the status bar at the bottom of SP Flash Tool window would go from red (Downloading DA 100%) to purple (Download BootLoader 100%) - but then it ends up getting stuck for about 10 seconds, before giving me the error "BROM ERROR: STATUS_OPEN_FILE_ERR (0xC001000E)".

The ONLY way I can get the flashing process to go through completion is by unticking all the options on the download table except preloader. Only then would I get the "OK" notification from SP Flash Tool. Since the instructions on the web tells me that I should be ticking all the boxes except boot and recovery, I would imagine that this is not the correct way of doing things...

Fortunately, the Write Memory part works (that's where I press Ctrl Alt V, choose the Write Memory Tab, pick the recovery_stock_works _after_brick.img and type 0x8000 in the Being Address field). I used the same procedure as when flashing. So far so good...

But then I would run into the same problem again when flashing using DA_PL.bin file (supposedly the final part of the solution), with SP Flash tool tells me "BROM ERROR: STATUS_OPEN_FILE_ERR (0xC001000E)" .

So I am at a loss on what to do next. I did see some other people reporting that they got to where I am but pretty much can't progress any further due to this STATUS_OPEN_FILE_ERR problem... so if anyone is able to get through the flashing process and get their x626 to boot up, please please please share their experience, preferably on this thread! :fingers-crossed:
