Hi B1-710 users,

I don't have the device and cannot help you other than with the info on this forum. I have searched and I have found the following three ROMs which can be flashed with SPFT:

Acer_AV051_B1-710_1.126.00_PA_CUS1

Acer_AV051_B1-710_1.128.00_PA_CA

The one included with the Flashing procedure is the WW_GEN1 version (Acer_AV051_B1-710_1.098.00_WW_GEN1). Previously we have also seen with other devices that PA_CUS1 and PA_CA devices have different hardware and could cause these types of issues. Do you remember what the ROM was before you started the flashing procedure?

Regards,

Nika.

Procedure is the same as A1-710. Make sure to use:

ROM-SPFT-B1-A71.zip

SPFT-B1-A71.zip

Unlock-B1-A71.zip

Begin Address = 0x1B88000

Container Length = 0x500000

Regards,

Nika.

---------- Post added at 10:32 PM ---------- Previous post was at 09:47 PM ----------

Flashing the full ROM is mostly for flashing a bricked device. If your device works fine, there's no reason to use it. When you do want to root the device, you can use the recovery provided in the Unlock ROM. It also seems I mixed up the files, so here's a complete list:

ROM-SPFT-B1-710.zip

SPFT-B1-710.zip

Unlock-B1-710.zip

Begin Address = 0x1F88000

Container Length = 0x427100

Regards,

Nika.

PS. I don't think I've seen any custom ROMs for these devices...
[Android General] *Detection*:
Thanks for the ROMs, but there is no secuoff.img with either of them, and using the one from the main tutorial along with the scatter from these new ROMs results in the same connect > disconnect pattern

So, again, no dice, appreciate the help though, thanks
[Android General] *Detection*:
I'm using my desktop PC, I've tried different USB ports, different USB cables, the drivers are installed correctly (as per instructions, and device manager is happy and sees "MediaTek PreLoader USB VCOM Port (COM3)" )

The connect > disconnect issue happens no matter what I have running on the PC, drivers installed or not, SPFT running or not, doesn't matter, - if the tablet is powered off, and I connect it to PC USB, it connects > disconnects twice, then does nothing but show the battery charging screen for a few seconds

The tape around the USB lead is just to distinguish it from other leads, not a cable fault, and it works perfectly for other working devices, as does the PC and all USB ports

I've got Acer a3-a11 and I can't seem to find the appropriate guide. I guess I can use these latest guides from post 926, but there is no info about the begin adress and container length. My device is on restart loop, now won't even show the logo, and it was all after the failed attempt to update to KK. Any help? Thanks!

P.S. I don't mind changing to CM or any other ROM if that is easier thing to do.
[Android General] *Detection*:
OK, some progress - thanks to nikagl for the link of a different SPFT, this one works (Partially)

I successfully flashed the "Write Memory" stage

But after disconnecting the tablet and trying for the full firmware flash, every single time, it hangs at this exact stage (8777950 bytes) and stops

But we're further than we were, I have some hope now

Any ideas?

---------- Post added at 00:32 ---------- Previous post was at 00:10 ----------

OK, another step forward, I managed to get CWM recovery flashed, and it works

Well, when I say works, it boots into CWM, and I can choose any of the options - but it will not format anything, it just freezes when I try

There is an error immediately after booting into CWM

E:Can't mount /cache/recovery/command

"" "" "" /log

E:Can't open /cache/recovery

---------- Post added at 00:45 ---------- Previous post was at 00:32 ----------

EDIT - In fact, CWM can not mount any partition at all, not even external MicroSD
[Android General] Shreps:
Try to flash each partition One by One instaed of the whole firmware. Maybe you will be able to find what part is crashing.

Remember to not try to boot until everything has been restored [emoji6]

Envoyé de mon One+
[Android General] *Detection*:
Right, thanks, I`ll give that a go today, I'm wondering if there is something wrong with the internal storage itself though, as CWM can not mount any partition at all, and SPFT can't write to any but recovery

Think I found the reason for the constant USB reconnect > disconnect cycle though

It seems to be this file "mtk_allinone_da.bin" in SPFT, once I replaced (Renamed and kept original versions) this file in the other SPFT builds, with this new one I got yesterday, all the SPFT tools stay connected (But they don't progress past the red bar)

--

I`ll update again once I've tried flashing each partition one by one, thanks :)

-------UPDATE--------

Every partition flashes fine apart from the following (The main ones)

ANDROID

CACHE

USRDATA

Those just freeze SPFT and then give a 4008 error

So... are there any other methods to force the flash, or manually flash from Linux / Windows ?

---------- Post added at 12:26 ---------- Previous post was at 11:50 ----------

And 58GB ?

There is no MicroSD inserted
[Android General] *Detection*:
OK, I have managed to get PhilzTouch recovery for the B1-711 flashed, and it is doing the same thing as CWM

Can not mount anything, can not wipe anything

Just hangs when I try to Wipe, and errors out if I try to mount
[Android General] rivaasjose:
good night!!

Following the post. Detection I'm glad you could advance your tablet recovery ... but I'm still with error 2004 ...

I was going to ask you some questions.

Nikagl will have the ROM happen in other download link ?? those I do not work there ... but I have the firmware of the first pag, that of shreps, they do not know if these will serve me ...

Detection as you did to solve the problem of connecting and disconnecting?

that way MTK_Allinn_Da.bin changed the file? just you changed your name or another file used?

PS: sorry for my bad English, I use google translator.

-------UPDATE--------

ok I have given an advance, I got what was Write Memory. I had to use the 3.1 version of SPFT. (if it was not that I use)

well ... but something happens when I try to write memory error appears 2004 .... Detection could move from this stage, some tips ?? not if I am using the firmware or something else.
[Android General] von_philippines:
thanks very much... downloading

---------- Post added at 05:58 AM ---------- Previous post was at 05:19 AM ----------

thanks nika. my tablet now working ..... :) almost a moth looking for a file to recover my device i installed a costum recovery that not comaptible to my device that cause bootloop situation.. thank again nika. for the firm ware B1-A71 Unlock.
[Android General] nikagl:
Try this SPFT:

http://bit.ly/1XYoXak
[Android General] rivaasjose:
Hi!

thank you very much, I'm downloading the file. as soon as you can try again! and waiting for the Detection tips!

Regards!
[Android General] *Detection*:
Google translate did not work very well, I don't really understand

But I managed to use the SPFT that you have just downloaded, to flash the "Write memory" stage - then I managed to flash everything apart from the 3 main partitions as I posted above

The stage I am at now, is that I have a working PhilzTouch recovery, but I can not get any further
[Android General] nikagl:
I really don't know. Did you try the other firmwares? To me it sounds like those partitions are either different in your model (due to hardware differences for certain firmwares) or have become corrupted somehow? Just to make sure: there's no way for you to figure out what ROM was originally on this device?

Same for that recovery. The reason it's not working would be if the partitions are different than the recovery expects...
[Android General] rivaasjose:
Great!! I'm very happy!

thanks Nikagl, the version that you download from your link works perfect!!! Detection as saying,

It was a problem of file MTK_AllinOne_DA.

I try to be clear on the steps I do.

-- I did the part of "Write Memory" and right! "yellow circle" on my monitor.

-- then try to flash on "download" but the file I downloaded, only contained "resque 710" and "710 Unlock and CWM" I do well and right! "yellow circle" on my monitor.

-- I had previously downloaded the firmware B1-710. but when clik “download.” I see Error 4008 (the same mistake, of Detection)

-- I individually deal with each .IMG file (according shreps advice: Try to flash each partition One by One instaed of the whole firmware.) I get Error 4008 when wanting to "download" in the android.img file and file cache.img

-- I turn on my tablet (I am impatient, I know not powered on). I get this result: Launches the Acer logo. after this, skips the logo, and the tablet is turned off

I do not know to do.

it may be that the tablet is restarted, because you miss the Android.img file?

I can use the file Android.img another firmware?

What advice would you recommend?

Really my sincere gratitude. thank you.!
[Android General] *Detection*:
They are the two conclusions I have come down to also

Either wrong images / scatter file is listing the wrong parameters for this specific model/revision B1-710

Or the partitions have become corrupt / damaged

Although the latter seems unlikely, DATA, SYSTEM and CACHE all corrupt, but recovery etc does not... I don't really buy that, possible, but more likely to be what I'm trying to flash being mismatched

And yep, also agree that flashing custom recovery not specifically for this device also could very well be looking for those partitions in the wrong place

Problem is, flashing the correct recovery (At least it is listed as being for the B1-710), results in no recovery at all

I've tried flashing about 3-4 different ROMs with Scatterfiles (All scatter files are identical) all fail for those three partitions only

I have no way at all of finding out what was originally on that tablet, it was bricked when I got to it, so never got any further than stock recovery, which froze instantly too...

Thinking about it, the corrupt partitions sounds slightly more plausible, when I first got my hands on the tablet, I booted to stock recovery because it was stuck on the Acer logo - when I chose to factory reset, stock recovery froze on formatting /data

That was how this whole thing started

Wondering if there is any other method to force flash via ADB or SHELL from Linux ?

---------- Post added at 11:12 ---------- Previous post was at 11:10 ----------

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

Identical issue -

Two of the same tablets, with exactly the same problem...

I think we need a different set of images / scatterfiles to use?
[Android General] nikagl:
Hi [MENTION=6925043]rivaasjose[/MENTION] and [MENTION=4369943]*Detection*[/MENTION],

Tough case. Not sure what to do either and it seems I'm the only one really responding here :) . Another option would be to write the IMG file using "Write Memory". Check the hex value in the scatter file to see which IMG should be written to which part of the memory. Using Write Memory removes several constraints, for instance when using it to unlock the tab with secuoff.img.

And yes, ADB Shell can be used (with dd) but for that you need ADB access. And when writing with dd you write towards a partition similar to how the recovery will do it so I doubt that would be different...

Regards,

Nika.

Is it possible to root an Iconia B3-A20 (MTK MT8163)?

Please help.
[Android General] nikagl:
Haven't seen it before. Anyone?
[Android General] *Detection*:
Great idea, Do you know what I would add to the Container Length HEX section for each partition?

In the scatterfile it only has the specific image HEX which I imagine is the begin address?

I've tried a few different ones from the scatter file and it keeps freezing at the same point, but it does try to flash it

EDIT - Even with no container length added, it still stops at the same place
[Android General] nikagl:
I'd expect container length to be automatically populated, based on the size of the img? Or to be sure, calc the image size back using hex calculator.

LOL, check the filesize just above it. ;)

One more thing, check the scatter file. The partitions seem to be in the right order. for instance:

ANDROID 0x2ae8000

CACHE 0x42ae8000

= 40000000 = 1073741824 Bytes = 1048576 KB = 1024 MB = 1 GB

System file is 675.383.708 bytes = 644 MB (fits in 1 GB). Not sure what happens if you flash something smaller in a bigger partition, but would expect it to write 0s.

Sorry, just guessing here. I would start with the filesize and see what it does. I'm sorry there's noone else with experience on this...

One more thing, also checkout the region address, begin address and end address in the SPFT when you load the scatter file :)
[Android General] *Detection*:
:) Found the size above it just after I posted lol

Well, it's definitely trying its best,

CACHE has flashed 100% and passed

SYSTEM freezes at about 5%

USER_DATA freezes at 49%

Could the scatterfile be wrong?
[Android General] nikagl:
I've searched all sources and all sources have this scatter file. I wonder whether the device has a different SOC?

When googling the SOC (MT6577) I do come accross other scatters too:

http://www.mediafire.com/download/7203np0h49444ug/MT6577_Android_scatter_emmc.txt

Those are probably for other devices and no way of knowing whether it would be similar for B1-710
[Android General] *Detection*:
I'm wondering that too, especially now that someone else has the exact same problem

And that 3 partitions (2 now) won't flash fully / at all using the download tab

Does the B10-711 have a similar scatter or the same?

---------- Post added at 19:49 ---------- Previous post was at 19:48 ----------

Ah nice, thanks, I`ll give that a try and post back after walking the dogs lol
[Android General] nikagl:
I noticed another guy having a B1-710 (@LeonReno) who had success flashing it. Can you maybe try a procedure like this:

http://androidmtk.com/create-scatter-file-for-mtk-devices

Or "Read Back" your device with SPFT and provide the files it creates?

Regards,

Nika.

PS. I'd be really carefull flashing imgs to partitions that are wrong (ie. use scatters that are not for the device). You can brick the device even more (where it won't allow SPFT to flash at all)

---------- Post added at 08:55 PM ---------- Previous post was at 08:50 PM ----------

See the post above - maybe you can help?
[Android General] *Detection*:
Well, I've tried just about everything my brain can cope with tonight

That new scatterfile got 1-2% further than the original one, but still froze

I did manage to flash USER_DATA fully this time

So CACHE and USER_DATA have been flashed (If they were the correct parameters), just SYSTEM is the trouble child now - and tab still hangs on the Acer logo :)
[Android General] nikagl:
Without SYSTEM, nothing will flash. I wish I knew another way to figure out the right partition locations. The scatters are the ones we downloaded from ROMs for B1-710 which litter around on the internet... that's all we have and can work with... sorry. One last thing I realize now. Let's see whether we can find a download @ acer website. We might be able to use the boot.img if it has one and/or analyse the updater-script to see what partitions are in there?

Here's what I can find on the acer website:

http://global-download.acer.com/GDF...EMEA_18#_ga=1.162150524.1955896958.1449694398
[Android General] *Detection*:
It has it's own scatter file, but unfortunately it has the same parameters as the ones we've been using

ANDROID 0x2ae8000

CACHE 0x42ae8000

USRDATA 0x6e6e8000
[Android General] nikagl:
Well... the scatter inside that zip is the same. Also the partitions mentioned in the updater-script are the same in the extracted recovery.img.

Do we have any insight where the tab came from? Is it european (ie. EMEA)?
[Android General] *Detection*:
It was bought from Argos in the UK, other than that, this is the sticker on the back

http://i.imgur.com/QfvaENB.jpg

Nothing else on it that could help that I can see
[Android General] nikagl:
Cool stuff what you can find about just the FCCID:

https://fccid.io/HLZB1710

https://fccid.io/document.php?id=1976626
[Android General] *Detection*:
wow, very cool :)

Nothing about partitions that I can see though, can you see anything that might help ID it so we can try finding the correct firmware / know if we already have the correct firmware?
[Android General] nikagl:
Nothing at all :( I'm afraid we're getting stuck. Hopefully that guy with the B1-710 that it worked for or someone else can make a scatter file and/or device dump/download with spft?
[Android General] *Detection*:
Fingers crossed, well, thank you very much for your help up to now

Gonna call it a day for tonight, I`ll check back tomorrow and see if there is any new hope

The guy who's tablet it is (missus' brother) has already accepted that it is 90% likely to be dead, so... anything that can be done, is a bonus
[Android General] rivaasjose:
Hi!!

I'm a little busy, I read new messages ...

I do not understand much. But I ask: if a problem happens in "memory write" tablet can die?

another question: can be used scatterfile firmware or other device (b1-711 or a1-xxx), if testing the tablet can die?

PS: I use leonreno firmware (firmware file for flashing B1-710 [4.1]) I use it. and get Error 4008.

PS: I read a comment on the website of Acer, a guy who does not jump logo your tablet b1-710, take it to warranty and restore its tablet with a tablet firmware B1-711. I have to do some research on that.

any progress on b1-710, write. I be very grateful

Acer A3 20 FHD Formated

Hello,

another Question for a formated Acer A3 20 FHD and some attempts:

I made a Backup and a scatter file with Droidtool 2.5.3 from an working acer A3 20 FHD, but flashing with SP Flash Tool from this Files did not work:

[IMG="Files from Droid Tool"]http://www.fotos-hochladen.net/uploads/filesfrommtk3sv9aehrzu.jpg[/IMG]

[IMG="Scatter Droid Tool"]http://www.fotos-hochladen.net/uploads/scatteracera39y4d2bip7e.jpg[/IMG]

Next i made a Complete Readback from a working Acer A3 20 FHD with Sp Flash Tool and converted this Files with Droid Tool, but flashing with SP Flash Tool didn't work again:

[IMG="Rom Sp Flash Tool"]http://www.fotos-hochladen.net/uploads/romspflashtooqf5jz7ngy0.jpg[/IMG]

Then i mixed the Files from the Flashtool and the Files from the Acer "Acer_AV0K0_A3-A20FHD_1.023.00_WW_GEN1" Firmware and then flashing worked but i couldn't start the tablet:

When flashing a full ROM it's fine to flash it as it will be locked after flashing anyway as soon as you reboot... I don't think it matters. Anyone else an opinion?

Why are you flashing the full ROM anyway?
[Android General] royalt213:
How on earth did you get the USB drivers to install? I have tried everything under the sun, including trying the bogus B1-750 drivers from the Acer site and the A1-840FHD drivers. Nothing has worked. I would be grateful to hear what you did.
[Android General] nikagl:
Which OS?
[Android General] royalt213:
Windows 7 x64 Ultimate
[Android General] nikagl:
Never had issues with Win7 x64. On Win10 I needed to disable driver signing or something like that. On Win7 I just used this procedure:

[*]Download and unpack drivers: http://bit.ly/1hujx8o

Run "install_driver.exe" AS ADMINISTRATOR and wait about 2 minutes. After this you will see a popup window (Driver for xxx installed), close it and reboot your PC.

Turn your tablet off and connect it to PC. You will see a popup message "New device detected". Wait until drivers will be installed OR until tab will disconnect from PC.

Nevertheless, you could try (google it, there's many howto guides):

Disable driver signing

Turn off UAC

What driver did you use? What download? What device do you need the drivers for? For which purpose do you need the drivers (SPFT, ADB, Fastboot, etc)?

A3 20 FHD Formated

Hello,

i'm not able to flash the tablet like described, because i'll get the Brom Error 2005.

I can flash the tablet with a new Flash Tool Version and deleted "Checksum.ini" file from the existing files. The Flash completes 2 times with a green circle but the tablet still makes no noise or boots up.

[Android General] royalt213:
Okay. So I tried this, but it still didn't work. I got excited because it was the first time I got the device to be recognized as something other than "A1-850" or an MTP device. While it was off, it was recognized as "Android," but the drivers still wouldn't work. Then when I turned it on, it was finally recognized as "ADB Device," but still wouldn't recognize the drivers.

The drivers I have tried are:

The "official" drivers from the Acer site. Except, I'm pretty sure the link is wrong, because the drivers are listed as "B1-750."

The generic Google USB driver from the Android SDK Manager.

The drivers from the link that you posted.

Beyond that, I have tried installing and reinstalling all of the drivers, as well as rebooting the device and my computer several times. I have tried doing all of these things both with USB Debugging enabled as well as disabled. No matter what I do, I get an error that the driver installation was unsuccessful.

I have also tried turning off driver signing, which had no discernible effect. I haven't turned off UAC, but I am not having an issue with being denied the ability to install the driver, so I don't think UAC is the problem. Though, I will give it a try anyway.

I need to be able to use ADB with the device, primarily because I want to root it, but also because I would like to use ADB for other stuff.

Is this the exact procedure you used to install the drivers?

By the way, here is the info on my device:

Model: A1-850

Android Version: 4.4.4

Kernel Version: 3.10.20+

Image Version: Acer_AV0K0_A1-850_RV00RC01_WW_GEN1
