I have a B1-720 Iconia infected with viruses. I found some firmwares for SPFT and tried to write them but always an error popped up with SPFT like this

BROM ERROR: S_BROM_DOWNLOAD_DA_FAIL (2004)

[H/W] Fail to download DA to baseband chip's internal SRAM!

with B1-72x - SP Flash Tool v3 and the same with newer SPFT SP_Flash_Tool_v5.1352.01 version

I also found this firmware to flash from recovery

WW_GEN1 4.4.2 RV0BRC05 1.070.00.zip

but it is also not flashed properly and in the end I am receiving an error.

assert failed: package extract failed ("boot.img", "/tmp/boot.img")

Install from sdcard complete

Where can I find a 100% working SPFT and flash file for this model?

Hi moriveon,

Thanks for the guide for the tablet Iconia B1-710. Do you think the error having my tablet when flashing.

“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] Moriveon:
[MENTION=6925043]rivaasjose[/MENTION] did you try to flash without battery connected to the tablet?
[Android General] rivaasjose:
Hi!

Yes! I try to blink whitouth battery and with battery. but the result is the same.. in the SPFT, error menssage 4008 and "BROM_DLL_V5.LOG and BROM_DLL.LOG Would be created and record more detail information"

I open my tablet acer iconia B1-710 and I see MT8317ATA. I search and I realize that B1-a71 have the same MT.

I will try instead of B1-710 do so by following the steps of b1 - a71 ??

it seems that the android file cache and user data, were corrupted or not supported, since the rest flashing perfect

Hello again,

Is it possible to backup the firmware on my B3-A20 ?

thanks you very much
[Android General] GerasVille:
Hey guys,

I just tried to root my Acer Iconia One 10 B3-A20 (not A3-A20!!!) with Kingsroot and it kinda worked. I could grant root access to apps and modify some stuff, but unfortunately after debloating something went wrong and my tablet is in a bootloop. I performed a hardreset so I could start from the beginning. After completing the android set up I was thrown instantly to another bootloop. After some researches I tried to do the android set up but without the last step and I installed another launcher via playstore and email. Afterwards I could start and do whatever I want to do. Unluckily I'm again in an bootloop after I did a restart. I can't enter the android set up procedure anymore and can't install any apps from the playstore.

Right now I can do following:

- I can access the download mode and try to do something with adb, BUT I'm unauthorized and can't tick the USB debugging think as you can imagine

- Try to flash something via recovery, but untill now I could not flash anything

Does anybody have a suggestion? Stock recovery is still accessible, but somehow I can't flash anything.

Hope anybody can help me out.

Thanks in advance. Best Regards,

GerasVille
[Android General] f3n3k:
that's why, i want to do a backup of the firmware, acer don't give it.. But i don't know how to do it...

So just for know, can you say what's app have you uninstall for have this probleme of bootloop ?

thanks you very much
[Android General] GerasVille:
Thanks for the reply. The first bootloop was caused by the missing launcher. Now, maybe the supersu binaries caused it, can't tell for sure.
[Android General] Shreps:
Do you know which version of firmware you had ? The SKU part is the most important, was it a WW_GEN1 ?
[Android General] GerasVille:
Is it possible to see this information anywhere right now? I have the version with the MTK MT8163 quadcore, if there are any other variants. I never received any updated, so it should have the same firmware as everybody.

[Android General] davidam091:
Hello nikagl! You probably don't remember me, but you helped me with my A1-810 like 4 months ago. Well, I tried everything you helped me with, and it didn't seem to be working. I gave up. Today I realized I still had my tablet in my laptop bag, so I plugged it in to charge and tried booting it up, figuring, what the hell. At first, it stayed on the Acer splash screen, and the right 3cm of the screen was distorted, like a broken LCD. I rebooted it. Suddenly, I found myself at the new user setup screen! I have no idea how or why, but after all this time, it works! Just wanted to say thanks.

Now, what's the best method to root and get custom recovery (and a nice, clean ROM) on my A1-810? Please direct me. Thanks, nikagl!

Strange fot it going into a bootloop just like that. Wasn't rooted? Why can't you get onto recovery? What do you mean "or charging"? I would try factory defaults from recovery again. If doesn't work, you can try to flash the SPFT ROMs provided in this thread, that has always helped me on my Acer A1-811. Make sure to use the right ROM, do you know what the ROM version was for your device before all this happened?

Can someone please help me with a tablet? This is an Iconia A1-810 and the first time I powered it on, it was stuck on the splash screen. Nex I booted to recovery mode and wiped flash to restore it to stock, but when I've restarted it got stuck to "erasing". Next thing was to find a way to unbrick it, and as soon as I tried to flash with SPFT the only thing it is able to do is flash the preloader. Tried all lots of stock firmwares, A1-810 Unlock and CWM\Unlock and CWM and Rescue folder.

Also, when i try to write EMMC memory it just fills the red bar and gets stuck at white bar with 0% and ends with BROM ERROR: ?? (5)

I even tried SP_MDT to no avail.

Can someone please provide me a way to unbrick this Acer Iconia?

I have acer iconia a1-713 firmware. I follow the instruction that i need to uncheck the preloader. But i got error and when i charge it theres no led or display. Also it is not booting
[Android General] nikagl:
I can only ask what I asked before:

What firmware was on your device?

What firmware did you flash using the instructions?

Without that info, it's going to be impossible to help you.

If you cannot access the device with SPFT you will have to:

* Long press Power button (60 seconds or more) might help

* Drain the battery (do not connect USB, wait a long long time)

* Disconnect the battery which required opening the cover/device (instructions on youtube)

Regards,

Nika.
[Android General] jeromeeroles:
The firmware was kitkat. Then flash kitkat firmware also.
[Android General] nikagl:
If we ask which firmware, we need you to provide something like the following:

AV0K0_A1-713_RV02RC05_WW_GEN1

AV0K0_A1-713HD_RV05RC03_WW_GEN1

So I ask again. What firmware did you have BEFORE you started the flash and what firmware did you flash (check the filename of the files you flashed)?

And just to make sure. Is your device an A1-713 or an A1-713HD?
[Android General] jeromeeroles:
I dont know what is the firmware before i flash. The firmware Id used to flash is Acer_AV0K0_A1-713HD_RV05RC03_WW_GEN1
[Android General] nikagl:
And you have a HD device? If not, you flashed the wrong firmware and now need to go to an Acer service center to get your device fixed. Always make sure to flash the RIGHT firmware on the RIGHT device.
[Android General] jeromeeroles:
thanks
[Android General] nikagl:
And answer questions when they are asked. Every reply you have given without answering several of the questions... Still don't know what device you actually have (although asked already 3 times)... ;)
[Android General] fredamexis:
Can someone please give me an insight on this please?

[Android General] nikagl:

If that doesn't work, I'm afraid you're stuck with a bricked device and should try an Acer service center. Btw... make sure to first fully power off the device:

* Long press Power button (60 seconds or more) might help

* Drain the battery (do not connect USB, wait a long long time)

* Disconnect the battery which required opening the cover/device (instructions on youtube)

Thank you so much for your sugestions. But that doesn't work either. What I've noticed is that this Acer Iconia A1-810 also exists with MT8125 chipset. Could it be that my problem is because of this.

Sorry, I wouln't know what to do else. Again, try the above suggestions and/or another PC/cable/USB. That's all I can suggest. Maybe [MENTION=4493088]Shreps[/MENTION] or [MENTION=5889030]Moriveon[/MENTION] have some additional suggestions?
[Android General] Shreps:
I don't understand what you mean. A1-810 is only MT8125 AFAIK. So all GEN1 firmware we have are for this one. A1-811 is MT8389 for the 3G module, but that's all.

I read through that, and I'm having some trouble following it.

First, it says download firmware from the Acer website, but there is nothing under "firmware" for the A1-810. Under O.S., I downloaded both files that are for WW.GEN1, but I'm not sure which one to use. Then, it goes into instructions for the SP Flash Tool, after he finished telling me to try using recovery first. Honestly, I'm not even sure how using a file from the Acer website is gonna give me root. Can someone please explain the process to me a little clearer? I'd appreciate it. Thanks.

S_da_sdmmc_write_failed (3149)-acer a1-811

Thank you so much for your guide.

My Acer Iconia A1-811 was bootloop. When I tried to do the factory reset, it wasn't solved. It even stuck at logo--erasing (factory reset process)--back to the recovery mode automatically. When I clicked 'wipe data/factory reset' again, it would back to logo--erasing (factory reset process)--back to the recovery mode again.

So, i found this thread and tried to follow your guide 'Flash Full ROM'. Never unlocked/unbricking my tablet before. I am newbie at this thing.

When i tried to download (after did the write memory), it worked until yellow progress bar appeared. But, it always stuck at 37% with BROM ERROR S_DA_SDMMC_WRITE_FAILED (3149).

I had tried to download it without its battery, but still.. it was stuck at 37% with error 3149.

Now, I even can't turn on my tablet.

Do you have any suggestions?

Thanks!
