Flashing: Acer_AV0K0_A1-830_1.006.00_WW_GEN1_FLASHPKG.7z

ACER A1-830

Dear Anyone,

Is it possible to flash this kitkat backup image successfully Acer_AV0K0_A1-830_1.006.00_WW_GEN1_FLASHPKG.7z successfully ? I was able to flash the Jelly Bean backup image successfully, but the kitkat one always fails. Please help. The image was downloaded from SDC's [TOOL KIT] myKIT_BATCH page. http://xdaforums.com/showthread.php?t=2681783

P.S. -- My Acer A1-830 is one of the rare models that has camera issues after installing the KitKat update over the air. (Camera takes too long to load... up to 3 minuets) I was able to succesfully go back to JellyBean (which does fix camera) and try and try again, but it seems the camera bug is persistent without fail. I'm hoping wiping and flashing a trusted image will help me with the camera issue.

dumped images into flashable zips

I just tried the recovery in the link you posted. Yeah it works on the A1-830. Could you please convert the dumped images into flashable zips ? (at least the kitkat one) I really want to install one of the trusted dumps everyone else is using... I am assuming you can't flash the dump via the CWM Recovery method, right ?

euh this was rather new to me to flash the tablet via fastboot, it took some time understanding the process..

i finally managed to do fastboot and since my device is slightly different then dumped build i flashed with all 3

fastboot flash boot Acer_AV052_A1-830_1.014.00_WW_GEN1.boot.img (PASSED FINE)

fastboot flash fastboot Acer_AV052_A1-830_1.014.00_WW_GEN1.fastboot.img (PASSED FINE)

but then:

fastboot flash system Acer_AV052_A1-830_1.014.00_WW_GEN1.system.img.gz

My tablet was with kitkat a1-830 build number a1-830_1.007.00_WW_GEN1 (4.4.2) ModelNO: A1311 picture two posts above.

Hi Just wondering if you could provide a bit more assistance, I am stuck on the bootloop. All I can get into is recovery nothing else, how do you actually get it into download mode you can use the image to flash he device.

Everything you need for droidboot is provided in mykit_batch + update.

[General Questions and Answers] machina77:
For a full system flash to 4.2.2 I used these commands in linux.

(Windows/Mac should be the same assuming all USB drivers are installed)

fastboot flash boot Acer_AV052_A1-830_1.014.00_WW_GEN1.boot.img

fastboot flash fastboot Acer_AV052_A1-830_1.014.00_WW_GEN1.fastboot.img

fastboot flash system Acer_AV052_A1-830_1.014.00_WW_GEN1.system.img.gz

fastboot flash recovery Acer_AV052_A1-830_1.014.00_WW_GEN1.recovery.img

fastboot erase cache

Then (following advice from IcemanSR ) in Droidboot select Recovery, once in recovery select wipe data/factory data reset, when finished select reboot system now.

A full flash will allow OTA updates, and i'm not interested in rooting the tablet (still time for Acer to give us Lollipop!)

Great work from social-design-concepts :good:

You can use Titanium backup to freeze it. I believe it is called Acer Live Updater.

WIFI only works near router...

I all! After all the OTA updates, wifi only works near the router!! If i step away 2 or 3 feet it loses the wifi connection. And it happens with more than 5 different routers...

So i followed the tutorial and downgraded to 4.2.2 with sucess....but...wifi stays with the problem! I dont know what can i do to fix this! There's a bunch of people with the same problem after update but nobody know how to fix.

I know how to root, downgrade, etc.... but this is out of my league.

Please, someone help kindly....it's my young daughter's tab....

Thank you all!
[General Questions and Answers] jim620:
I had the problem and had to send the tablet in to Acer to get it fixed. According to the repair docs, it stated that the wifi antenna was loose. I don't believe this was all there was since the wifi stopped working right after I updated to 4.4 but nonetheless the problem was fixed. I haven't updated any other OTA besides the one for 4.4 which broke the wifi in the first place.
[General Questions and Answers] SpicyMcHagiss:
update?

I am still on 4.2.2, I have never updated. I have successfully rooted but I have not installed CWM yet, has there been any updates to it yet?
[General Questions and Answers] blackstripe:
Thanks for posting this! I just bought one from cowboom.com the other day for $65. It must have been returned b/c of dismal wi-fi reception. Sure enough, I opened the case and found the wifi connector to be unhooked. I hooked it up, closed the case back up, and it was fixed!
[General Questions and Answers] dawgdoc:
The post of social-design-concepts you quoted takes you to the third post of his thread, it is about the tethered CWM. The post links to a download page for the 5 Nov 2014 version. In his same post he links to another post in the thread that has a link to a newer version download, the 3 Dec 2014 version.

Be aware that CWM is not actually installed on the ACER tabs. You are able to run and use CWM while tethered to a PC. It will not install a ROM, nor will it sideload apps with adb. It seems best for backing up your device.

Also, when I updated from rooted 4.2.2 to 4.4.2 I lost root. Fortunately root was easily regained using SDCs myKIT_BATCH. I am not aware of any more recent updates to our tablets.
[General Questions and Answers] LS720Boiii:
Is there anything out yet? running 4.4.2 unrooted obviously
[General Questions and Answers] dawgdoc:
There are a couple of methods that can be used to root a A1-830:

Try this thread Linux Tethered CWM Recovery Version. I have used it to boot into the tethered recovery and make a nandroid backup, clear cache, dalvik, etc. Try the trigger2 script. If this does not work thee is a method developed by social-design-concepts, search for the myKIT_BATCH thread.
[General Questions and Answers] social-design-concepts:
If the mykit_batch method worked the tethered cwm should I derived to recovery.launcher off the same concept I used in mykit_batch
[General Questions and Answers] dawgdoc:
That's what I thought.

I used the myKIT_BATCH to root my Acer. I have only used the tethered method to boot into CWM recovery, using trigger 2. Therefore I had no reason to try rooting my device with the tether method.

I saw where vache has a CWM.img for this device, but for whatever reason I could not flash it with fastboot. If only I had a flashable CWM.zip.
[General Questions and Answers] social-design-concepts:
did you try with the adb / fastboot binaries he posted they are different than the aosp binaries
[General Questions and Answers] dawgdoc:
I tried several adb/fastboot binaries to no success. Both of those vampirefo posted in the OP of his Linux tether thread; his and the smaller one from Google he posted, his dated Nov 2014 and Google's dated Dec 2014. I also tried an older binary I had been origianlly using, dated May 2013 from android-sdk-linux platform-tools. I will try all of this again in a few days and verify that I did try all of these.
[General Questions and Answers] social-design-concepts:
got it your on linux unfortunately i believe you need to uses the ones [MENTION=1829889]vache[/MENTION] posted for windows to flash the recovery.img they are different than standard aosp binaries
[General Questions and Answers] dawgdoc:
Yes, Linux. If I don't work it out, which is my first option, I will find a Windows computer to borrow. I borrowed a Windows computer to use your myKIT_BATCH. If I ever get it to work on Linux I will post it for others.

if i sent my tablet back to acer to get my money back or what ever do you think having that kinguser thing stuck on there would be a problem? i didnt buy it directly from them i bought it through target.com. because if no worrys ill probably just get a different tablet.

i dont suggest return it just yet i feel we are very close to progress i mean the tab is just out less than half yr just give it bit more time i know its annoying, there are not root programs out there that works ive tried many chinese root programs since i can read them.

to get rid of kinguser have you tried factory reset?

ive tried everrrrryyy thing i've had it about two weeks and ive probably factory reset it 3 times trying to root/get rid of that one specific root. i have till the 18th to return it and if i do return it and every things A okay i'm probably going to get a dell venue.

i tried looking into towel root a bit more any idea what any of this means??

== Introducing modstrings! ==

Modstrings are a way to modify the exploit parameters for your obscure phone.

This is only if your device can't be towelrooted.

Click "welcome to towelroot v3" 3 times and enter text.

1337 method(0-3), align(0-1), limit_offset(0-8191), hit_iov(0-7), temp_root(0-1)

method: which syscall is used in the blocking thread, try them all

align: which alignment to use for the iovs, try them all

limit_offset: 0 is probably the right value here, otherwise close to the samsung value and a multiple of 4

hit_iov: which iov to overwrite to cause block

temp_root: do a temp root putting su and daemonsu in /sbin, good for HTC and Motorola, doesn't fix exploit

To fix, align and method are probably your best bet(4*2=8 values), hit_iov maybe, limit_offset if you are desperate.

== Examples ==

Most phones: "1337 0 1 0 4 0"

New Samsung: "1337 0 1 7380 4 0"

Temp root: "1337 0 1 0 4 1"

took a long shot and tried messaging geohot....
[General Questions and Answers] stapler85:
i have already tested the first 2 options combination from the towelroot mod string and doesnt work (2 x 4 total 8) i did not test rest of the options since i really dont feel much luck at all, also each time it fails root you have to reboot the tablet so it is time consuming, but you might wanna test other combination if you got time.

what it means is that there is different ways you can test the root method yourself by using his app

e.g 1337 1 1 0 4 0 is one way, then 1337 2 1 0 4 0 is another, but 1337 0 0 0 4 0 is also another, and so forth, within the range given of modifier allowed per each option. each combination of range is ONE root method, so in order to test you need to try each combination once then move onto next range combination, hope it makes sense, it took me a some time to figure what it meant.

so by the instruction, given it mentions the first 2 modifier is likely to be best bet so thats why i only tested that combination.

ADB/Fastboot

Just purchased the A1-830 today, will get here Thursday. I'm proficient with adb and fastboot (way too many times having to set devices in and out of stock roms and recoveries), so should be able to get you what you need provided you can give me a rough idea of the commands you need.

Hopefully someone can help sooner, but if not, I'll assist.
[General Questions and Answers] dawgdoc:
I was not paying attention to file formats.

I successfully rooted my Acer A1-830 with the myKIT_BATCH developed by s-d-c

I have successfully booted into your tethered CWM several times and performed various tasks; nandroid, wiping cache, etc

I was hoping to flash the CWM developed by vache for this device to have a permanent custom recovery. It was only after trying that I noted his CWM was a .img file instead of a .zip file. Therefore I could not flash it from within tethered recovery. I will need to wait until later, battery low, to again try flashing from fastboot. I had previously tried it with your adb/fastboot binaries and with those I originally installed for sdk-platform-tools.
[General Questions and Answers] vampirefo:
fastboot flash recovery nameofimage
[General Questions and Answers] dawgdoc:
That's what I tried, but it simply gave Fastboot Waiting. IIRC
[General Questions and Answers] vampirefo:
That's cause you don't have your user set up to use fastboot, so either setup your user or use root.

sudo fastboot flash recovery nameofimage
[General Questions and Answers] dawgdoc:
Pretty sure I tried sudo, but maybe not. Also, I had edited my .bashrc to contain the path to the directory where adb and fastboot were located. I will clean up my files to make sure there is only one instance of each and that $PATH is correct.
[General Questions and Answers] vampirefo:
Nope you didn't try sudo, I am an old old Linux user, so I know how Linux works, second of all forget about .bashrc just forget you even heard of such a thing.

fastboot waiting means exactly that it is waiting for authorization, under sudo you would have no waiting.

Now take the two binary files and do below.

sudo cp ./adb /usr/local/bin/adb

sudo cp ./fastboot /usr/local/bin/fastboot

Then either make or edit your 51-android.rules to allow your user to fastboot.
[General Questions and Answers] dawgdoc:
What I must be remembering is sudo not working with the Linux tethered recovery: sudo ./start_recovery That is it didn't work until I switeched to trigger 2.

Need a deleted app and odex

Hello. I rooted fine but does anyone have a copy of the clearfi_photo_2.3.2.003.apk and odex? I only have the apk but not the odex file.

If I put these 2 back on the system/apps folder with the right permissions and do a reset, will it be recognized as a stock app again? I tried installing and it always tells me that it is not installed. It is outdated but I would rather keep this than the updated one.

I don't want to flash the entire system IMG just to get this back?

P.S. Does anyone know why Gallery intermittently flashes a "No external storage found" even if I have an ext SD card on there? I get it to work by clearing data and cache on the Gallery app info but I don't want to have to keep doing that. Any fix? I formatted my ext SD and other apps read it just fine except for Gallery.

Thanks
[General Questions and Answers] dawgdoc:
I don't have that version of the apk or odex to offer you, I disabled them when I bought the device and never took any updates that did not come from OTAs. The reason I am responding is that the files present are in /system/priv-app on my A1-830.

[General Questions and Answers] dawgdoc:
You do not state if there were any error messages or not. Is the device still functioning and the only problem is that it does not have root? Or, does the device no longer function?

A better way to root than this method, since the developer no longer supports it, would be to use Intel Android Devices Root / Temp CWM Session It was developed by the same person -- Social Design Concepts. I didn't actually use it, I used Linux Tethered CWM Recovery Version, it is a derivative of the other. T2, trigger 2, worked for me with the Acer Iconia A1-830.
