Hi, my A1-810 is bricked after flashing the official uptade.zip from the Acer site :(

(no vibration, black screen, only the META Mode / VCOM MTK is regconized by my Windows, but don't have a stock SP Flash Tool ROM)

Hope you will be able to provide it !

For the scatter, I can't make it using MTK Tool, but in the official update.zip, there is a scatter file used by the recovery :

PRELOADER 0x0
MBR 0xc00000
EBR1 0xc80000
__NODL_PMT 0xd00000
__NODL_PRO_INFO 0x1100000

Hey Shreps ........are these for the A3-A10 tablet? It starts to install the update but stops part way and says Upadate.zip is not correct. It shows the system I have and the one of the update and they match up to the last set of numbers. The zip is JDQ39/1398089240, and my system reads JDQ39/1404362981. Could this be enough to stop the update?
[Miscellaneous Android Development] Shreps:
Yes, the previous OTAs are for A3-A10, they're OTA JB to JB, but if you are on

acer/A3-A10_ww_gen1/zara:4.2.2/JDQ39/1404362981

it means you already have the latest JB Version for A3-A10 : AV052_RV05RC01

From this version, you can only upgrade to KK with A3-A10-KK-AV052_RV05RC01_AV0K0_RV04RC06.zip (acer/A3-A10_ww_gen1/zara:4.4.2/KOT49H/1403862718)

Maybe you can try to factory reset + flash the KK OTA ?

EDIT: Do you have ADB working in recovery ?

If someone could make a dump of the latest JB A3-A10 ROM (at least a pull of /system), would be cool to help in debugging
[Miscellaneous Android Development] tccc143:
I will give it a shot. But at this point it seems I may have a brand new brick on my hands. Not sure about ADB under recovery.....once its charged back up again I will try that to. Thanks for the assist...........

[Miscellaneous Android Development] pjlsantos:
Using the 128MB file it starts to update but then I get an error about Books.apk and the update is aborted... This seems to be really messed up...
[Miscellaneous Android Development] tccc143:
So I don't have ADB in recovery. But I did get something different this time when trying to install the KK update. Basically it says this KK update package is for JDQ39/140436281 OR KOT49h1/1403862718 (one posted above earlier). Then it tells me I have JDQ39/1381307974 and need the KK update for this build #. Is it possible to locate that file for my specific build???
[Miscellaneous Android Development] pjlsantos:
I have the exact same versions as you in the update error, and the file we need to use is 635429978593493857_OTA_Acer_1.0_AV052_A, the one with 42MB. Using that one first the update starts but then gives me an error when checking the apks, halting on Books apk. I've been trying to change the update script but keep smashing into the signature verification... thinking of sending this to Acer and spending some cash... bah
[Miscellaneous Android Development] tccc143:
Do you have a location of that 42mb file for download? I wan to see if I get a different error or the same. It seems that we are right at the edge of figuring this out....

A1-810 Scatter file. Now what?

So Calingo sent me this scatter file based on Shreps post from Saturday. Has anybody successfully used the scatter file to downgrade to Jellybean that can post a guide?

I don't know enough about SpFlashtool to risk it myself.
[Miscellaneous Android Development] cabalio83:
Ok, now the scatter file actually load into the too,

I have been wondering what partition I need to flash and wich files I should assign...

At the moment I cant think of two files:

- boot.img that I can find inside Update.zip from ACER

- system.img I have saved when I ran the toolkit before rooting from scratch (I also have my rooted system.img)

I've loaded them and I have the program set like this.

Didn't try to flash 'cause in the end my tables is at least working, ok I have no root but a hard-bricked piece of plastic isn't any better...

If someone has some hint about how to go on I am listening.

:good:
[Miscellaneous Android Development] swing4thefence:
I know how you feel. It's so frustrating to be soooo close and yet still so far. I stared at it last night until my eyes were blurry trying to figure out how to even tell it what source to use. It never occured to me to simply click the location line.

Like you though I've been staring all day at that screen afraid to proceed without knowing what to do. Calingo knows so hopefully he will publish a guide soon.

[Miscellaneous Android Development] pjlsantos:
For you guys that know a lot more of this stuff than me (basically everyone :D ), i'm trying to change the update script inside the acer update file, but when I do that i get signature error, obviously. I'm trying to create a new signed update, but for now without success... do you guys think it's possible to do that with the stock recovery? (I bet it's a no, without having Acer keys...)

Now about rooting A1-810.

opera_fan@4PDA made modded CDS Info APK, so button "Start" is active now. There's two modded versions.

Acer Iconia A1-810 FlashTool Guide

Sorry For Late Reply :mad:

Open SP Flash Tool

Create a Folder In Any Directory Add These Files In it

Boot.img Found In Acer Update.zip ( Not Necessary )

System.IMG In This Thread Or Your Original Stock If You Have Any backed Up ( Like I Had :fingers-crossed: )

And The Scatter File Attached Or The One You have If Works

Now Locate The Scatter File In The Folder And SP Flash Tool Should Recognize It And Load The Scatter File With The Appropriate IMG and Partition. Or This Can Manually be Done ;)

Scatter File Assigning System.img to Android In SP Flash Tool Is Right Step :good: And Boot IMG is Not Necessary But Still Can be Selected for The Boot Partition :cowboy:

Click Download And Then Connect Your Tablet Dead/Turned off And It Should Detect Your Phone If You Have The Proper MTK Preloader Drivers Installed :D And Start Downloading

But If Its Not So Then make Sure You have The Drivers Or If Your Device Is Not Connecting As Preloader Mode Not Even Showing In Device Manager Use A Pin to Press The Reset Button And Wait 5 Seconds And Then try Connecting It to The PC :good:

And If You Device Appears In MTK preloader Mode For Just Seconds and Then Disappears :( Then I Am Helpless Cause Thats The Problem i am Facing And I Am Still Trying To figure Out But Its Not A Problem Actually thats Normal If You Download Something It Will Detect And Not Disappear But If You are Not downloading anything Will SP Flash tool It Disappears After A Couple Of Seconds But In My Case I think Its A problem Because Even When i Click Download In SP Flash Tool And Connect My Device Keeps On Disconnecting :(

Does anybody know where I find the guide to root the Acer tablet without the toolkit? I found it earlier this week but I can't find it today.
[Miscellaneous Android Development] swing4thefence:
Found it here: http://xdaforums.com/showpost.php?p=40188901&postcount=275

Unfortunately I can't figure out how to untar the system.img.gz to work on it. I've tried the tar command but it doens't do anything and when I try to Gunzip the file I get "unexpected end of file" which is incidentally the error I was getting in the toolkit that was the whole reason for wanting the instructions for the manual root.

Any advice? It's not the tablet because my wife and I both have one and it doesn't work on either one anymore.
[Miscellaneous Android Development] Moriveon:
Hm, AFAIK system.img.gz is an image of FAT(32) memory, so at least you can try to open it with R.Saver (download will start automatically after few seconds). But I think this soft is not on English...
[Miscellaneous Android Development] swing4thefence:
From my research, the "unexpected end of file" means a corrupt file. This seems to be supported by the fact that I re-booted to windows and tried 7zip it also told me that there was corruption. So now I"m wondering why the toolkit is pulling a corrupt file. I have done a couple of factory resets so it shouldn't be due to anything I've done on the tablet.

Any ideas?

---------- Post added at 02:21 PM ---------- Previous post was at 01:47 PM ----------

Apparently it WAS due to something I did. For some reason downloading the KK update (not installed) causes the toolkit to pull a corrupted file. I just did another factory reset and I didn't download the update and the root process completed without issue. Wonder why? Does anybody have a copy of the KK update for a1-810? because Apparently I cannot root with it on my device so if I am to try the rootkeeper method I will need another source for the update.

Until then I guess I'll stick with Rooted Jellybean.
[Miscellaneous Android Development] Moriveon:
I think I can deal with rooting an A1-810, just need to do some tests. I'll post in any way - success or not.
[Miscellaneous Android Development] superdragonpt:
The problem is not rooting (there's an way to root this new MTK KK 4.4.2 Builds w/ kernel 3.4.67) problem is that users reported that the tool haves spyware (chinese tool)

Hang in there, there's work being made (i also have 1 device with the new MTK KK)

[Miscellaneous Android Development] swing4thefence:
Which tool? Is it PC spyware or android spyware? Do you have to leave the spyware to keep root?
[Miscellaneous Android Development] voom:
I had my A1-810 rooted from scratch with the toolkit. In order to make updates I unrooted and made a factory reset / wipe data in the recovery. After that I could install the big pre-KK Update. Then the KK-Image was downloaded, but the update breaks with a red triangle in the robots stomach every time.

I know of other people with the same problem. Any help on how I could get the update to complete? Is there a way to flash an image that really puts the tablet back to the original state or some other way to get around this? Maybe even flash KK with SP Flash Tool? Does someone have an image or could pull one of a fresh A1-810 KK?
[Miscellaneous Android Development] cabalio83:
I had the same situation. You can fix it flashing update.zip in recovery.

Follow what I wrote here to get the system.zip you need

http://xdaforums.com/showpost.php?p=54715546&postcount=3449

Then follow this guide from Acer site (pdf file) for the actual flashing

http://global-download.acer.com/GDF...&Step3=A1-810&OS=ALL&LC=it&BC=ACER&SC=EMEA_17

You will go back to a clean, stock 4.2.2, that allows you to get the other two OTAS to KitKat without errors.

BTW once you're back to stock you can also try Calingo's tutorial to keep root in KitKat if you like

NmAa, post with mirror links.
[Miscellaneous Android Development] Moriveon:
NmAa, why do you want to root A71 with toolkit? You can use CT Root to get root without PC.

Guide:

1. Close all running apps.

2. Install CT Root and launch it.

3. Press 2nd button ("Мульти ROOT").

4. Wait until dialog with tablet info will appear.

5. Press "Root" and wait.

6. One more window will appear, press 1st button ("Интегральная стены").

7. Wait ~10 seconds. You can see "Network error" text, just ignore it.

8. If your tablet will not reboot automatically in 10 seconds, reboot it manually.

9. Install SuperSU and BusyBox from Play Market. Also you can remove CT Root app.

Later I will create a mod of CT Root with English support and another UI.

8. Gmail

9. Google Play Magazines

10. Google Play Cinema

11. Google Talk

12. Google+

13. Koala_acer_startup

14. Launcher (only if you have installed another launcher and don't need this)

15. Music FX

16. Picasa Uploader - removable

17. Play Books

18. Play Мusic

19. TalkBack

20. Top HD Games - removable

21. Browser (if you using another browser)

22. Calendar

23. Maps

24. Video Editor - removable

25. Android Keyboad (if you using another keyboard)

26. Contacts

27. Мedia (circle on icon) - removable

28. World time

29. News and weather - removable

30. Weather - removable

31. Google search

32. Dictionary provider

33. Registration

34. Тags

You need to give a try for BloatFreezer, it's about 160kb.

For camera, there are three ways:

1. Go to Settings→Apps→All, choose the Camera app. Stop it, the clear data and cache. Reboot and try to launch camera app.

2. Wipe cache via recovery. Reboot and try to launch camera app.
