Ok, thanks. I'm out of ideas here. Do you really have A3-A20FHD or is it an A3-A20? I think I would try to open the device and take the battery out... If SPFT has not shown any colours I really don't think the tab is bricked, but just hanging in the boot process somehow... :(

What is shown in the device manager of Windows when you connect the tab? What is the device name?
[Android General] nikagl:
In this screenprint you show it's an A3-A20:

And here you mention it's an A3-A20FHD:

Installing the wrong firmware on the wrong device may brick your device. However, the SPFT you're supposed to be using should clearly warn you about incorrect partition types for your device...
[Android General] bmttinman:
I have no idea what you mean?
[Android General] nikagl:
This was not for you. Read my post above...
[Android General] bmttinman:
The first three pic are before I started. The last pic was after it bricked.

The web site says it is A3-A20-K3NB.

Thanks to everyone
[Android General] nikagl:
You killed your tab because you installed the wrong firmware and must have ignored the warnings when flashing it. A3-A20 has different speed and ram than A3-A20FHD, and therefore has different partitions and scatter file...
[Android General] JanniekM00:
Thanks!

I have now a unlocked bootloader & CWM on my B1-A71. Thanks!:D
[Android General] bmttinman:
That Is what I think also. Thanks again.

I am trying to unlock my acer iconia b1-710. I get a BROM error when hooked to spft. Here is my log. Can someone help?

https://mega.co.nz/#!I8QEnaTZ!uZHyxH9jfaoV0YH_sOgenMStsczAOLuHOoMdc5eKecs
[Android General] nikagl:
What's the BROM error you get? I've gone through your log but didn't really see any other error than:

ERROR: OperationIndicator::QueryDADLHint(): da_dl_type(??) error, could not find DA download hint!(.\OperationIndicator.cpp,98)

Please also post screenprints of the steps you took so we can compare for user errors.
[Android General] jimmytwotimes.parker:
Basically, the tablet won't stay connected to pc. It connects and disconnects while using spft.
[Android General] nikagl:
Would still like screenprints. Try different cable, port, PC and/or drivers...
[Android General] jimmytwotimes.parker:
When you say screen prints do you mean screenshots?

---------- Post added at 09:59 PM ---------- Previous post was at 09:56 PM ----------

The tablet disconnects and connects while I'm hooked to PC even before using spft.
[Android General] wbrambley:
How about starting SPFT, getting the files ready, click to flash then plugging in your tuned of tablet.
[Android General] jimmytwotimes.parker:
That's the procedure I follow but even before I start spft. I'm hearing the tablet connect and disconnect from pc. When I use spft, everthing is good until red progress bar 100% ,then I get error.
[Android General] nikagl:
Eh...right...what else? screenshot/screenprint/printscreen/prntscrn of the files you selected in spft, buttons you press, etc.

Again: try other usb, other port, other cable

Aha... so you do get the red bar. again: screenprint/printscreen/screenshot/prntscrn please. Also of the exact error, as requested before.

So, yes, A1-810 and A1-811 have secured Kernel that disable /system remount

And whithout kernel sources we can't remove this security.

I'll test to make sure, but nevertheless you can mount system from recovery so that should be enough, right?
[Android General] jareee:
thanks for explanation :good:
[Android General] Shreps:
Yes, via recovery is enough on many cases, but not having /system in RW mode can affect some root apps which needs to edit /system on the fly :)
[Android General] jareee:
if i'm not able to RW /system , busybox , xposed and other must have apps cannot run correctly from ROM :)
[Android General] Shreps:
Xposed or Busybox can be flashed through update.zip via recovery :)

Thanks
[Android General] nikagl:
What help do you need? Please be specific. Here's help [MENTION=4493088]Shreps[/MENTION] offered to you before:
[Android General] jitThink:
A1-841

I have applied the SPFT firmware, however I have feeling that the device performance is slower than before, WIFI connection keep disconnecting. That why I want to go back with stock recovery.

Regards,
[Android General] nikagl:
SPFT is a stock firmware. SPFT is just a method. With SPFT you can do it from your laptop. The files need to be selected in SPFT and it flashes the firmware on your device. It's also the way to flash a custom recovery, or custom firmware if available but for your device there's no custom firmware. The firmware you flashed is stock.

Other method is through recovery. You can only install so called signed zip files with a stock recovery. With a custom recovery you can install unsigned zip files, for instance to root the device.

The only thing that might be different when flashing with SPFT is that you can flash a firmware with different SKU. The SKU is for EMEA_GEN1 which signifies for which region or for which third party the ROM was created. For instance, you may have a TWN device and you can flash it with a EMEA ROM to get certain languages. Or you have a GEN1s device and flash it with a GEN1. In that case you have a single sim device on which you flash a dual SIM ROM. The second SIM icon will appear but will not work.

So main question to you: what was the ROM which you had on your device before you flashed the new stock ROM with SPFT?

Regards,

Nika.

Hi! After some hours of tries, the root checker says i got my A1-810 rooted, but the SuperSU app keeps saying that I gotta update the SU Binary and I can't do it...

Also the Titanium backup doesn't work, cause the app can't get root access.

How can I fix it? thanks

EDIT: I just did it LOL Don't really know how, but the binary SU is now updated and Titanium Backup works like a charm!!! Thanks guys!!!

Installing SuperSU should be done through recovery. Make sure to select that from the SuperSU app settings and install the update from there.

[Android General] jrmpinto:
Yeah I've already seen the bloatware remover but it uninstalls almost all my apps, and I need apps like Gmail or Calendar. Is there any option to remove only apps like Zinio, Simeji, 7digital etc?

Thanks
[Android General] nikagl:
I usually freeze the app from the system settings before updating it and never bother to look at them again.

You can do two things:

1. Use ADB SHELL to connect to the device when in Recovery and run the commands manually:

rm /system/app/7digital.apk
rm /system/app/ZinioReader.apk
rm /system/app/ZinioSettingsProvider.apk
rm /system/priv-app/simeji.apk

You may need to chmod the files to be able to delete them. Never did it manually.

2. Tell me which bloatware zip you want to use (ie. for which device) and I will remove all lines from the updater-script that are not relevant. Also mention detailed list of all files you wish to remove. Btw.... it's not that difficult. Just unzip the files in the zip, modify updater-script by removing irrelevant lines of apps you don't want to remove, zip the file again and run the zip from recovery...

Regards,

Nika.
[Android General] jrmpinto:

Good job! I can test them on A1-811, I think they should be compatible. Only CM port might have issues because A1-811 has a data card that might not work when using an A1-810 ROM?
[Android General] Shreps:
Nice !

But we can see on your screenshot that you're using JellyBean version of recoveries (old version like CTR v2 instead of 3.3), meaning, JB version of Kernel too I guess.

Which means you will not be able to flash KK or LP ROM I think.

Plus, did you check your partition layout and be able to perform backup + factory reset + restore without problem ? (and without loosing nvram ?)

Thanks for your informations ;)

Hi,

I am having trouble with SPFT. My tablet(B1-710) is bricked and I want to unbrick it by installing the stock firmware but I keep getting the following error (Attached as a picture). Another thing is that I keep hearing the connecting/disconnecting sound. Meaning my tab keeps disconnecting after maybe one second. Here is what I have tried till yet.

Tried using different cable.

Tried using different port.

Tried flashing with battery cable disconnected.

Also tried removing the battery cable just as soon as the progress bar reaches 100% Red.
