Hi Malk,

Also following up on FireDiamond's respons, could you please make screenprints of each step you take? From those we may be able to see what you're doing wrong. Post screenprints and explain. It's utterly important to follow each step by the letter and make sure the right files are selected, usb is unplugged/plugged before flashing, no reboot takes place after writing secoff, etc. So please, post clear screenprints and steps and we can probably help :)

When flashing a full firmware do NOT uncheck any of the files. In the full firmware all files are signed, so that should be ok and unbrick your device after flashing. For full firmware follow the steps from the guide:

[Android General] malkthealk:
Sorry guys, looks like I misunderstood?

Point 4 in the link states:-

I had changed something in the build.prop file before this trouble so assumed I had 'messed' something up? This is perhaps what confused me. Many thanks for the replies and I can't wait to get home tonight and try again.

Keep up the good work please?

Malk
[Android General] nikagl:
Ah, right, agree :). Well... In your case I would try:

1. Just system (you tried that already but then you get preloader error)

2. Just system with secro-sign

3. Try system with preloader and secro-sign

4. Try system with preloader and dsp_bl and secro-sign

5. Select all except userdata. That way you may still be able to keep your data

But if it doesn't have much on it - it's best to flash the whole thing and just start with a clean tab :)

Regards,

Nika.

My sincere thanks go out to you guru's who have the patience to help us minions in our hours of need, especially Firediamond, Shreps and nikagl, who have been so, so helpful.

You guys do so much to help us and also do so much for the environment keeping the glut of old/broken phones in the world down at the same time and my heartfelt thanks go out to you all. My friend kept telling me to bin mine!

[Android General] nikagl:
[MENTION=6409946]atak90[/MENTION], A1-811 cannot be rooted because Acer has not yet produced the sources for the kernel in KK. You can therefore not mount /system as r/w. That's why have asked (numerous times) which zip you are trying to install.

If you definately want to root, please use the root from scratch method as explained here:

A1-810 bricked: please help me

Hi all, i have my A1-810 bricked. Last days it has stopped starting and then i've tried to do a factory reset. The result is the loop with the screen attached!

Now i'm trying a restore of factory image with the "moriveon" guide in first page, because the tablet doesn't load in recovery, so the last hope is to flash it with pc.

I've installed the usb driver but the tablet isn't recognized from the pc when connected.

The pc install the driver correctly, i restart the pc, and when i connect the tablet to the pc it install something similar to "MT65xx preloader", but the next step to write memory stay always in "searching" without any colored progress bar.

Could you help me to solve this problem?

Thanks in advance

P.S. sorry for my english
[Android General] nikagl:
Just to make sure: you turn the device entirely OFF before selecting Download / Firmware Upgrade and after selecting Download or Firmware Upgrade you connect the tablet? It should automatically switch on and start the flash from SPFT.

Please note that I am not sure about moriveon's guide (and not going to check it either!). There's just one guide for this thread (officially):

http://pastebin.com/raw.php?i=4FYSSUk8

You can either try the Download, but in your case I would use the Firmware Upgrade method. First write the secuoff with Write Memory and then go back to the first tab and do a Firmware Upgrade. I have done that several times to get my A1-811 from bootloops, hanging in recovery, etc., etc., and so far it has always been successfull. Note that Firmware Upgrade DOES erase your entire device (including data) but as you were doing Factory Defaults anyway, that shouldn't be an issue. Second note, possibly just in my case, when I use factory defaults (either from recovery, or from the Settings menu in Android) my devices goes into bootloop and I need to do a Factory Upgrade from SPFT, also the ROM mentioned in the readme is JB not KK, but that's for A1-811 only and it can easily be upgraded after the Factory Upgrade method :)

Good luck!
[Android General] miticomv:
Thanks a lot nikagl...

Tomorrow I'll try ad then I report here!
[Android General] miticomv:
Well...

I'm stopped on 3.4 step of the guide.

When I click WRITE MEMORY and i connect the tab to the pc nothing happen on the pc, no progress bar. The status bar in the lower part of screen shows SEARCHING (when there was USB written before clicking WRITE MEMORY).

The tab start on the known loop screen everytime I connect it to the pc.
[Android General] miticomv:
I don't want to bore you, but, please, could you help me?

Thanks
[Android General] Shreps:
Too options here

- your driver are not well installed

-or, your device is not in META mode, in this case, you should try to remove/disconnect your battery and retry the whole process without the battery. At the end, when the flash process is completed, put back your battery.
[Android General] miticomv:
Thanks for the reply.

I think the drive is well installed: following the guide, i can see on my pc "drive successfully installed"

I've tried to follow the guide removing the battery, disconnecting the plug under the cover, but when i connect it by usb the tab start vibrating without start on and wothout connection to the pc.

Would i remove completely the battery,not only unplug?

What's exactly META mode?

Thanks
[Android General] miticomv:
Well i've unblocked all windows file from 8.1 secure block.

I've reinstalled driver

The Tablet is recognized as MT65xxpreloader (is it correct?!?)

I launch flashtool ad on step 3.4 i stop on the attached screen

Any suggestion?!? Thank
[Android General] Shreps:
Are you sure you plug the USB only after this screen ? (and not before)
[Android General] nikagl:
Yes, just pulling the white plug is sufficient.

Did you turn off tablet, disconnect usb, then press write in spft and then connect usb? In exactly that order?
[Android General] miticomv:
Yes i've tried in this exact order:

- with the battery plugged it start in thw loop screen with android robot and the word "erasing"

- with the battery unpluigged it start vibrating with the monitor off

In both cases nothing happens on pc, no progress bar
[Android General] miticomv:
Here is my step

1.2.1 install usb driver as administrator, and the reboot

1.2.2 after reboot, turn the tablet off and connect it to pc (the tablet turn itself on with loop screen if the battery is plugged in or start vibrating is battery is unplugged, but on pc always the same screen)

Disconnect the tablet from pc

Launch flash_tool ad admin

Follo the step 3.1-3.2-3.3

3.4 Press Write and then connect the tablet (the tablet turn itself on with loop screen if the battery is plugged in or start vibrating is battery is unplugged, but on pc always the same screen)

And here i stop.

Thanks in advance for your patience

[Android General] nikagl:
[MENTION=2979876]miticomv[/MENTION],

Tough. Although it looks like it's all the right steps, here's another check to make sure you're using the right steps AND the right SPFT, Drivers, etc.:

1. Drivers: http://is.gd/mtk_drv (see http://pastebin.com/raw.php?i=4FYSSUk8)

2. Firmware: http://is.gd/f810_44 or try the JB version http://is.gd/f810_42 (see http://pastebin.com/raw.php?i=4FYSSUk8)

3. SPFT: http://is.gd/spft81x (see http://pastebin.com/raw.php?i=4FYSSUk8)

4. Install drivers (looks like that was ok, just make sure it's the right drivers, see above)

5. Turn tab off, disconnect batttery

6. Disconnect tab from USB

Flashing ROM you have three choices to try:

1. Flash ROM with Firmware Upgrade (make sure all files are checked)

2. Flash ROM with Download (make sure preloader and secu are NOT checked)

3. Flash ROM with Download after write of secuoff

Flashing is done:

1. Click Firmware Upgrade or Download

2. Connect tab to USB

If in none of the above steps the tab is recognised by SPFT, I'm afraid you have a bricked tab and I wouldn't know what to do other than to contact Acer Support...

Regards,

Nika.
[Android General] miticomv:
Thanks all for the support, unfortunately without good results.

I have followed all steps, and i've tried the flash both without than with battery, but it has stopped always at the same point.

A final doubt: do you think the issue could be that there isn't specific drive for Windows 8.1 64 bit?

Today i'll try on a Win7 notebook hoping for a good result! I will update you

Thanks all again
[Android General] miticomv:
Well i've done a good step!

The issue was with Windows 8 driver.

I've made the steps on another notebobok with Windows 7 and finally i've gone over the step 3.4

On step 4:

4.1 Red progress bar appear and disappear

Always after 57 second the flash process stop with the screen attached.

With that code error i've tried to connect the tablet to another usb port, with or without battery plugged, with two different cable.

The process of flash never arrived to step 4.2 Purple bar.

Any suggestion?

Come on guys we're near to the finish! ;)
[Android General] nikagl:
Did you try all 3 methods writing the partitions? Also, in download mode, try each partition separately to see which is causing the format error. I think, in the end this is the root cause off your issue which might be a hardware issue too...

The pc doesn't recognize more the usb tablet connected.

Now probably it's gone!

I was getting the following error in SP Flash when I click download on my 4.4 A1-810:

BROM ERROR: S_SECURITY_SECURE_USB_DL_IMAGE_SIGN_HEADER_NOT_FOUND (6045), MSP ERROR CODE: 0x00

After trawling through Russian forums (Google Translate FTW!) I was eventually able to deduce that there is something wrong with the download listed on the pastebin guide.

Remember this is ONLY for A1-810 - no idea if any others are getting this message.

I subsequently found a version that worked perfectly for me

Unfortunately I don't have the requisite number of posts to post URLs, so the best I can do is direct you to Google and find mdforum, a Russian site; you're looking for thread 17714 .

Hopefully someone else will post the direct link.
