Good day everyone.

I have a little question about my tablet.

I have an iconia B1 -720 and I read all about the unlock/CWM but I see a "new" image on the Mr. Shreps page called "CWM_6.0.5.0-B1-720-Shreps.img"

My question is if this is safer than the CWM of FireDiamond's guide because I don't do it yet because the "VERY DANGEROUS TO USE" alert about I can brick my tablet.

If this is better. I need flash it of the same way of the guide or is another one?

Thanks for all and regards for the excellent comunity of here :D

(PD: Sorry for my bad english)
[Android General] torben5247:
will this tutorial work on 4.4.2 kitkat

Hi Nikagl.

Thanks for your reply!

I looked through the tutorial, looks good!

Have you tried it on the a1-810 with android 4.4.2 kitkat version?

Thanks in advance

Regards

Torben5247
[Android General] nikagl:
It has been done many times by others throughout the world. I did it on A1-811. Similar device but steps turned out to be slightly different, see first page in which [MENTION=4493088]Shreps[/MENTION] mentions my thread...
[Android General] torben5247:
Hi Nickagl

Where can i download zip file "A1-810 Bloatware Remover Script on FP"

Can´t find it, could you please help me with this also.

Thanks in advance

Torben5247
[Android General] Shreps:
You can try the process again but uncheck the preloader partition (in order to flash the whole tab except the preloader)

You can also try the opposite, flash only the preloader first, and if it succeed, flash the whole firmware but not the preloader.

I think the CWM specified by [MENTION=5889030]FireDiamond[/MENTION] and mine are the same (you should compare MD5Sum of the two files)

But I don't know if it's working fine, I didn't see many feedback for this tablet on this thread.

Comfirmed that the Guide works great on many A1-810 devices...
[Android General] nikagl:
It's on the First page

Hi everyone!

I have Acer Iconia A1 - 810, Runing KitKat, the scr from about tab:

images68.fotosik.pl/901/81bb6e078997aa60.png

I rooted it with Toolkit 0.9.4

It seems to be half unlocked - I Have SuperSU - Root Checker says i have Root permissions...

But System is RW protected - i can't change nothing in System Directory...

I just wanted to do one "small" change - Swap the sd with internal memory...

In the system dir i have the files:

fstab, fstab.fat.nand, fstab.nand

In etc no vold.fstab files...

I can only view the fstab, without perrmision to save any changes, and error when try to edit fstab.fat.nand and fstab.nand - read error.

Is it possible to swap the sd with internal memory?

If Yes - can someone tell me how?
[Android General] nikagl:
I am not sure about swapping memory, never did that, but you are right that rooting with the toolkit only gives you a very basic root. You won't be able to mount /system and add anything to it without doing the changes in the system.img with the toolkit and restoring the new system.img.

But... when you install the new recovery mentioned in the first post, You will still not be able to mount /system as RW when running android, but you should be able to mount /system from the recovery. You can modify stuff in /system that way, either through adb, or using recovery install zips...

An overview of the steps you need to take are:

1. Install drivers

2. Download SPFT

3. Download unlock zip that contains unlocked preloader and a secuoff file for your tab

4. Flash these files with instructions of Firediamond (see firstpage)

As soon as you have the new recovery on the device you can boot into it and run thae adb commands you need...

Do you have a page that explains how to swap the memory?

Regards,

Nika.
[Android General] grany:
I'll try it...

I don't have permission to fstab.nand and fstab.fat.nand

but fstab looks like:

# Android fstab file.
#<src> <mnt_point> <type> <mnt_flags and options> <fs_mgr_flags>
# The filesystem that contains the filesystem checker binary (typically /system) cannot
# specify MF_CHECK, and must come before any filesystems that do specify MF_CHECK

/emmc@usrdata /data ext4 noatime,nosuid,nodev,noauto_da_alloc wait,check,encryptable=footer
/emmc@protect_f /protect_f ext4 noatime,nosuid,nodev,noauto_da_alloc wait,check
/emmc@protect_s /protect_s ext4 noatime,nosuid,nodev,noauto_da_alloc wait,check
/devices/platform/mtk-msdc.0/mmc_host auto vfat defaults voldmanaged=sdcard0:emmc@fat,noemulatedsd
/devices/platform/mtk-msdc.1/mmc_host auto vfat defaults voldmanaged=sdcard1:auto
#/devices/platform/mt_usb auto vfat defaults voldmanaged=usb_storage:auto

so i think we have to change it to :

# Android fstab file.
#<src> <mnt_point> <type> <mnt_flags and options> <fs_mgr_flags>
# The filesystem that contains the filesystem checker binary (typically /system) cannot
# specify MF_CHECK, and must come before any filesystems that do specify MF_CHECK

/emmc@usrdata /data ext4 noatime,nosuid,nodev,noauto_da_alloc wait,check,encryptable=footer
/emmc@protect_f /protect_f ext4 noatime,nosuid,nodev,noauto_da_alloc wait,check
/emmc@protect_s /protect_s ext4 noatime,nosuid,nodev,noauto_da_alloc wait,check
/devices/platform/mtk-msdc.0/mmc_host auto vfat defaults voldmanaged=sdcard1:auto
/devices/platform/mtk-msdc.1/mmc_host auto vfat defaults voldmanaged=sdcard0:emmc@fat,noemulatedsd
#/devices/platform/mt_usb auto vfat defaults voldmanaged=usb_storage:auto

If i can view the other 2 files i will be sure then ;)
[Android General] DaskeKogarashi:
I checked and is the same. Then the only feedback is the guide and the alert. (a little of instability in some cases, I guess).

I going to test later and return to share if I could do.

Thanks for all dood. :D

Begin Address hex

Hi Nikalg

A quick question ;)

In the instructions the Start address is written to be "0x3d80000"

But the default address in spft tools is "0x0000000003D80000"

Do i have to remove the zero´s marked in bold? "0x0000000003D80000"

When you plug in the powered off tablet it short vibrates, how long time do i have to wait till the memory write process begin´s?

I have tried removing the zero´s so the start adress was "0x3d80000"

But nothing happened.

Thanks in advance
[Android General] nikagl:
Zeros can be left in place, it doesn't matter. Flashing should begin almost immediately (red bar if I remember correctly and then green circle). What happens in your case?
[Android General] torben5247:
Nothing happend, i plugged in the powered off tablet, it vibrates, i can see in device manager that driver is installed.

But nothing happens.

Am i missing something??
[Android General] nikagl:
Is the battery charge indication appearing when you plug the tab? Maybe try a different cable, usb port or PC. In my case it didn't work too (got the battery charge display) and when I tried several times with several cables and pc's it finally worked on one of them...

Regards,

Nika.
[Android General] torben5247:
The charger indication doesn´t appear.

I am using a windows 8.1 but i will try on a win 7 machine later today.

Thanks

edit: worked on xp.

Thanks!
[Android General] Bitmixer:
Pre-Boot is tricky

Many people are missing the fact that the pre-boot handshake only works for a few seconds, THE FIRST TIME AFTER POWER DOWN.

If you plug in the powered off tablet multiple times it can be recognized only at the first attempt. Further attempts will fail unless you boot the tablet up and down again.
[Android General] torben5247:
OK, good to know! Thanks for the information!
[Android General] terrycurls:
it mostly works...

hi

so I have an a3-a10 and maybe 8 months back I went through the procedure to unlock/CWM/root it with the 4.4.2 firmware via SPFT, mostly good but sometimes it misbehaves (refuse to charge, camera went funny for a while, etc).

Recently attempted to OTA software update in the android system, got error message "this firmware is for 'zara' devices, this is an acer_e3". Then tried to flash a .zip of the latest 4.4.4 linked here, through CWM; it said same thing.... which suggests that the firmware I loaded had the device type set wrong (/where is this set, is it bootloader or FW?). "Zara" is the a3 verstion nickname while "e3" is a liquid tab, and I'm damn sure that I didn't flash the wrong firmware file, so I don't understand that.

Basically I am resigned to full SPFT update to get the latest firmware onto it, my question is do I need to re-flash the bootloader etc as well? i.e. do I run through the instructions in the ROM flash guide (http://pastebin.com/raw.php?i=4FYSSUk8) and ignore the bits where it says "if you didn't unlock" or "if you didn't mess bootloader" (which presumably means if you didnt already flash over it) or do I do a total reflash and burn over everything?

any suggestions/explanation would be much appreciated.
[Android General] nikagl:
I'm afraid I don't have anyting to contribute here. I don't know the A3-A10 and it's recovery... I guess I would do a full SPFT flash just to be sure, but beware - you'll lose your data when you do it...
[Android General] Shreps:
Hi !

Many things here :

- The CWM made for the A3-A10 was a port from another device, that's why you have some prop mismatch. We never take the time to make a proper Recovery because this port was enough in order to flash SuperSU or Xposed or any generic zip.

- But, even with a proper CWM, you will not be able to flash Acer OTAs or Update zip, especially on MTK Iconia Tabs, because they are signed and protected on many ways

- In your case, if you want to upgrade, you have 2 options :

1) Use SPFT to flash the latest Firmware, it will erase all your data

Then you will have to do the unlock and root process again from scratch

2) Use the rescue file in order to undo the unlock and go back to the stock recovery

From there, you will be able to apply the Acer OTA with the BL and Recovery stock from Acer

After the OTA upgrade, root will be lost, so you will have to do the unlock & root process again!

A little more operations, but you will not loose data ;)

In any case, you can backup your data (Titanium Backup, etc.) before one of those options

Hope it was clear

Cheers,
[Android General] terrycurls:
Ok, thanks heaps for that - makes much more sense

keep up the good work, love you long time
[Android General] A1-724:
hi guys! juz new here. i would like to ask about the updates on A1-724 root. thanks & more power!
[Android General] Shreps:
The Acer A1-724 device is not a MTK SoC based one (it's a Qualcomm), meaning it will not be supported by this thread.
[Android General] Hamza91:
No Luck.

I tired what you suggested but it failed. I still get the same error before. I even tried with and without battery, but still the same error as before.
[Android General] Moriveon:
Of couse ANY methods will fail if you get #2004 error!

Let me explain shortly: something happened in hardware when flashing. For example, you could use the bad cable and it shorted the circuit for a millisecond (sounds crazy but it really happened with me).

There is only one way to revive your tabled (using Testpoint). PM me for more info and don't forget to attach HD photo of your tablet's motherboard ;)
[Android General] Hamza91:
Roger That.

Thanks I'll PM you :)
[Android General] terrycurls:
Hey so I downloaded everything fin, but on my win7 laptop the SP Flash Tool doesn't seem to work.

have tested with several different firmware archives - when I load the scatter it loads "PRELOADER" with no memory locations and then a blank line with nothing. the file doesn't load any of the other information.

please help
[Android General] Shreps:
Which file (firmware) dit you try to use ?
[Android General] terrycurls:
I tried with the latest release KK rc03 and the JB downgrade rc01 which is what I used originally I think (found it in my computer already), both downloaded from threads linked in this one. Also tried loading the CWM/unlock scatter with same result.

Seems like an issue with the SPFT itself, it just won't load scatter properly... I'm running as administrator and I've tried two versions of it (possibly actually same, just separate downloads). File list has preloader and blank, nothing else.

also when I click in the file list SPFT says unauthorised memory access or something and then crashes, which is what I had on my other computer when I tried to do this last time a few months ago and eventually gave up...

I did get it to work when I originally rooted the tablet, don't know why it's refusing now
[Android General] Shreps:
Can you post some screenshots ? your issue is very weird

[Android General] jrmpinto:
Hello, I need to send the tablet to repair, but i need to unroot it first. How can I do this?

It's a A1-810! Thanks!
[Android General] nikagl:
I would do a full flash of the latest A1-810 firmware with SPFT, that will wipe your machine and return it fully to stock.
[Android General] terrycurls:
The only thing I can think of is if SPFT does something with the drivers, as I also run a LG p500 (5 years and 2 versions of android later than it was designed for) and the usb drivers don't seem to play nice with things.

somehow between them (think it was the MTK loader drivers?) something has made it so that when I right click on a usb drive to eject it crashes explorer.exe :good:

I will burn a clean win10 on my laptop next month and try again with that, hopefully it fixes whatever is now wrong with both my machines.

Work like a charm!!!
[Android General] markosjal:
I recently tried a root method on an acer b1 a71 and that did not work. I came to this thread hoping to find a working solution but at first attempt not even downloads in the OP are available . where can I find a working how to for rooting b1 a71?? I really only want to root it as I have had lots of buggy alternate fimwares for other Android devices. The only incentive I can see for an alternate firmware is KitKat printing

Is there a concise how to anywhere without reading 66 pages of comments that has valid links??
[Android General] Ilisolokobwe:
Let them come
[Android General] nikagl:
Yes. See first page. Click the guide: Unlock Bootloader/Preloader + Flash CWM Guide by [MENTION=5889030]FireDiamond[/MENTION]

That explains exactly how to Flash CWM. After this, install SuperSU zip from sdcard using CWM and you should be all set to go.
[Android General] Moriveon:
Well, when I started to work with Acer 1.5 years ago, I had to read tons of posts. They were not XDA's "66 pages with <20 posts on each", they were 100-150 4PDA's pages with damn 50 posts on each one. So only after that I could translate some posts from russian to english to help users here. And now you do now want to read this just thread. Well, you are not a true forum user :p

and it is some kind of shame. We (I, [MENTION=4493088]Shreps[/MENTION], [MENTION=1829889]vache[/MENTION], [MENTION=4771007]swing4thefence[/MENTION], [MENTION=5484948]Calingo[/MENTION] etc.) worked so hard on this, and now noobs still PMing us with the ultrastupid questions like "how do I flash my xx-xxx?" - do not know about other guys, but this drives me crazy.

Moreover, only stupidity of people forces me to stop developing all my Acer-related projects - I did it 2 times already.

When I worked with forums a lot I realized: people on XDA likes to consume, but nobody repays. Funny fact: my guide was opened more then 2000 times (and also copy-pasted on many sites), but only guy donated to me (to the that guy - if you are reading this, thank you, bro).

Sorry for my negative emotions, but I really wanted to say this.

P.S. I some kind of happy of my exiting from Acer-related work.
[Android General] nikagl:
I can only agree with all of the above. Only thing is that I too profit from all the stuff other people post and develop, and even though I have to sometimes sigh and count to ten before answering a question, I continue to contribute so it feels ok that I profit here and there too. Even though I too must have helped 100's of people with my posts and replies, I have never had any donation... (not that I want one, just stating the facts)

There are producers and consumers, that is life... But you would expext some form of participation and self-action, like reading up, using friend google and so on. However, it seems the percentage of non-participating consumers is going up dramatically, andI feel your pain. But keep in mind that it could be much worse, where people do not even read the previous 5 posts, and asking over and over the same (even identical) question. End Customer IT support is a prime example of where you would never want to be... But there are numerous consumers of your product(s) who will never ask questions, and make good use of whatever it is you are doing or making, so do not despair, the silent majority is very happy with all the good things you have done (including me)...

Keep up the good work, because there are at least (for now) many more people that appreciate your work and who do not sink to repeating unwanted questions without taking the effort of research and reading long threads.

I hope you take heart from the above and keep doing the fine job you are, and have been, doing for such a long time. I am one of your fans and feel exactly what it is you feel (have been in IT for over 40 years)...

Hello everyone.

I dis a reset on my a1-810 and after that I didnt have any google play services installed, I mean, I barely have any apps on my tablet, I cant even go trough the initial setup.

Can you guys help me on how to restore the original firmware?

I have CWM recovery, I cant find any guide on how to flash the stock firmware image.

I would really apreciate some help.

Thanks.

This will explain how to flash a stock firmware. It includes the drivers, SPFT tool and firmware downloads in links on that page. If something is missing let us know...

Not unless you tell us what you did :). Flash a stock A1-810 ROM and do a factory defaults reset and you should be ok.

How did you get the drivers to work? I'm trying to root mine but I can't get the drivers sorted out.
[Android General] nikagl:
In the past I created recovery using the builder (Jenkins) for clockworkmod. I also bricked a tablet that way....what's the general feeling about using that?

Other method is porting one from a device with the same SOC.

Last method is creating it from scratch. It requires you to extract certain data from the device (to create BoardConfig.mk and recovery.fstab), and use unix to build the img:

http://xda-university.com/as-a-developer/porting-clockworkmod-recovery-to-a-new-device

Did all of it before on device I had, but for me it's impossible to do it without having the device itself... sorry... anyone else?
[Android General] mbl1979:
Thank you for the reply. I'm hoping its because its a new tablet (2014) maybe someone with the no how will get one in there hands. I'm saving up for nexus 9 :) don't get me wrong this tablet is nice and zippy, probably no ROMs for it anyways.
[Android General] Moriveon:
Well, if someone will gift (not sell) and ship to me some Acer tablet, I could unlock it, make recovery (but [MENTION=4493088]Shreps[/MENTION] does it much better), find testpoint and leak upload some firmwares for it :p
[Android General] Shreps:
I can Repack or Port a Recovery for the A3-A20, but you will not be able to flash it with a locked Preloader/Bootloader.

And as FD said, we need to get access to the device to try some dev on it like unlocking, recovery, etc.
