Well Done,

I even did not try the video call option.

Thanks :)
[Miscellaneous Android Development] nikagl:
Quickly tested it yesterday and yes, it's the same (ie. Video = SIM2 in other languages). I'll talk to Acer about it too ;)
[Miscellaneous Android Development] bertjuh1:
hope root works soon
[Miscellaneous Android Development] hackwerk:
What are you talking about?! Root works and always have worked and probably always will work?!

Use the CWM flash method and you are root, in any version.
[Miscellaneous Android Development] Timmmmaaahh!:
I even rooted without CWM or flashing anything. Don't even remember how I did it, probably some dodgy one-click method. Anyway, I'm happy to see there's some movement in the custom ROM area for us. You know what I think, I think LiquidSmooth should be ported to all Acer Liquid devices. I mean, that would only make perfect sense right? :D

I flashed LiquidSmooth to a Galaxy Nexus yesterday and was impressed by its speed and customizability. I have to admit I was a little sad when I had to return the device to its owner and return to my own stock ALE3, [rant]WHICH STILL DIDN'T GET ANY OTA KK UPDATE FOR SINGLE SIM DEVICES![/rant] Sorry, just had to get that out :)
[Miscellaneous Android Development] nikagl:
According to Acer it was released on Oct 3rd. That's when we received it on Dual SIM devices. Will check why not to the Single SIM devices....

If you have version Acer_AV052_E380_1.010.00_EMEA_GEN1s (RV10RC00) you should be able to receive the system update.

Which version ROM are you on?
[Miscellaneous Android Development] Timmmmaaahh!:
Thanks for looking into it... I'm on Acer_AV052_E380_1.005.00_EMEA_BGCs (don't know what that RV thingy is).

I just checked and still get the "Your device is up to date." message :rolleyes:

---------- Post added at 02:53 PM ---------- Previous post was at 02:50 PM ----------

Btw, I do have frozen "Acer Portal", "AcerNidus", "Facebook" and "LiveScreen" with Titanium.. but I doubt that has anything to do with it as I haven't seen any single SIM update reported in this thread.
[Miscellaneous Android Development] paugustin:
Hi,

you have a Belgacom device meaning that Belgacom has to valdiate the update before it's pushed to OTA... The delay might come from here.
[Miscellaneous Android Development] Timmmmaaahh!:
Haha! No way, that's kinda creepy. So that's what the "BGCs" is for? I indeed got this device back when I was on Belgacom (Proximus), won it thanks to a contest of theirs actually but have switched provider since. I don't understand how they have to validate an update for an unlocked device by default :confused:

Shall I get in touch with them?
[Miscellaneous Android Development] paugustin:
Yes unfortunately that's the way it is with devices sold by operators.

Even if they are unlocked they usually run a custom build that the operator must validate before it is released.

You can always contact belgacom but they will most probably not care at all.

[MENTION=2268917]hackwerk[/MENTION], can you add basic ROM flashing instructions to the first post?

Something like:

1. If you have the SP Flash Tool, make a backup with that too

2. Install CWM

3. Unzip OTA ROM (like http://global-download.acer.com/GDFiles/Application/OTA/635475739172038202_OTA_Acer_1.0_AV052_A.zip)

4, Copy FixPack-B.zip onto sdcard

5. Reboot into recovery

6. Make a full backup from CWM

7. Flash the FixPack-B.zip from CWM

8. Reboot & enjoy the new ROM

:D

Nika.

Rom porting again...

Hey guys, quick update for porting roms. tried alot of roms from a similar phone (jiayu g4), without much luck. Ported Color OS and Lewa os so far but theres so much left to figure out. the SD card issue remains on both roms (internal storage mounting as system storage i believe). swapping the vold.fstab files all over the system and boot.img didnt help at all so there must be another way to overcome this issue. For both roms there is no support for the quick button yet, as i dont know where to find the files related to it..

as for Lewa, I can't get the camera to properly work..need to play with the libs a bit :)

On the other hand..all other stuff is working correctly (wifi, 3g on first sim, cant check second, speakers, bluetooth etc).

If there is anyone out on this forum with this phone that can help me out in porting Roms to this device please send me a pm or just reply..I'm not too good of a cook and progress is very slow when you're doing it by yourself ^^

Regards

Not sure about the language in your case, I see it in all languages. Seems to be the same file, so development can start :)

[Miscellaneous Android Development] nikagl:
The OTA for Belgacom (BGC), Three UK (3UK) and some other branded devices for local operators are not controlled by Acer. The local operator first needs to approve the release... so I doubt that Acer local support can do anything about it...

Could someone share a backup of stock ALE3 rom?
[Miscellaneous Android Development] hackwerk:
No problem, which part(s) do you want? (see ROM DUMPING section)
[Miscellaneous Android Development] marcogiannetta:
I need system partition dump ( I think ANDROID (ext4 /system) ), logo, recovery and userdata.

I would port this awesome acer rom to my ALE2 :)
[Miscellaneous Android Development] hackwerk:
Ok, do you have a ALE3 yourself, or need me to do it? (use MTK Droid Tool, see my first post ROM Dumping section)

I do not want any personal data/info of mine spreaded, so I can not give you my data/usrdata partition.

I however DO have all others (see ROM Dump section) like logo, recovery (stock or CWM) and system, but I am still a little cautious :/

How and where do you want it (it is more than 1 GB!)?

You do know the kernel source is available eh? (see my sig)

And a another thing is: Android 4.4 will be released very soon, so wont you rather port that?!
[Miscellaneous Android Development] marcogiannetta:
Oh sorry I didn't think about your personal data, I forgot it's a backup, not a full rom.

I can do nothing with the source because it's kernel-related, I already got kernel.

I wanna test the rom on my ALE2 (I haven't got ALE3), so I need /system partition but you said it's over 1 GB, you should compress it. But don't worry, I'll wait Acer to post ALE3 rom on their site (they're very lazy :D).

P.S: could you give me ''logo'' anyway?

[Miscellaneous Android Development] hackwerk:
Ai! Bad news man, but your own fault (dropped your phone and cracked the screen?)?

Good question anyways: Can people please give part numbers and info of our ALE3 phone? And maybe cheap replacement sellers?

Or maybe phones that are (almost) exactly the same as our ALE3, including all Chinese clones (may come in handy for development, or replacements)?

Ps. Please keep this topic ALE3 flavoured, and not ALE2 development. Thanks.

I really hope they will fix the camera soon.

This is a bug which you don't expect from a company like Acer :eek:
[Miscellaneous Android Development] d3nnisd:
Yes D: Slipped out of the case...
[Miscellaneous Android Development] hackwerk:
Yes, it is ridiculous! A big company like Acer releasing a brand new phone with 2 great camera's as top feature, auto focus NOT WORKING OUT OF THE BOX?!

But it WILL be fixed, either in 4.4 or WE will do it! It is software/firmware based problem with autofocus.

Sometimes pressing and holding the big camera button on the back of the phone helps, or tapping the screen (in the middle), but:

Another camera app will be more convenient focussing (manually first time), like this buzzing amazing new (open source) app, included in newer CyanogenMods:

Focal

Install it and use it, its great, and by tapping your screen in the middle, it WILL (auto)focus! Load of options and modes like panorama and picsphere!

Anyone who can check the whole (stock) camera system (software/firmware) in the files etc or replace a problem file by another standard Android file (from a working clone phone perhaps)?

Please help fixin!
[Miscellaneous Android Development] hackwerk:
Noooooooooooo... :crying:

Dropped mine too, first ****in time, screen in 1000 pieces. WHY NO GORILLA CLASS :crying::crying:

[Miscellaneous Android Development] d3nnisd:
Contacted acer, but they ask about 80 euros for it...
[Miscellaneous Android Development] hackwerk:
For a complete replacement (inc repair), or part (piece of plastic of 1$) only?! 80 euro is half of the whole phone!?

Hi there,

I've "a bug" with my alarm ring. I've selected a ring saved on my SD card, but each time I reboot the phone the "Celium" ring is selected by default, and the morning is not at all the same waking up :)

I've tried to find the folder where the celium ring file is saved but I did not find it, Someone know where is it?

I think the issue comes from the location of my file, on sd card.

Someone else have the same issue?

Yes, me too! Now it's Acer_AV0K0_E380_1.006.00_EMEA_BGCs // kernel 3.4.67 // baseband MOLY.WR8.W1248.MD.WG.MP.V44.P10

One downside already, it came with MyProximus bloatware. Time to root and get that crap off :D
[Miscellaneous Android Development] Timmmmaaahh!:
Hm, turns out I'm not that great at this flash rooting, little help?

I'm stuck at when SP Flash Tool needs to ReadBack the rom thingy... I turn the phone off, load the scatter file in "Scatter-loading File" (PRELOADER is in red, is that bad?), go to the Read back tab, Add a value, double click it, save it as "ROM_0", Enter the length (have tried 0x3380000 and 0x43500000, one tutorial says you need to use RECOVERY, the other says CACHE) and click OK. Then I click Read back, connect the phone to USB (wait until it goes to the battery charging) and then turn it on. I never see the green "OK circle", the phone just boots normally. What am I doing wrong? Could someone explain this to a goof like me please? :)

I have tried Flash tool 3.1344.0.212 (as suggested) and 5.1352, no luck.
[Miscellaneous Android Development] Schumi_wk:
Just installed the root at the girlfriends phone and had about the same issue.

I did it like hackwerk described. You need to install the file while your phone is on and make sure SU is on your SD card, than turn your phone off pull out the cable and put it back in than sp flash should do it's work. After that boot it to cwm with the volume+ and power but keep the volume+ pushed. If everything is ok you should have root.
[Miscellaneous Android Development] Timmmmaaahh!:
Success!!

Stupid, stupid, stupid... I overlooked one silly issue, VCOM drivers! This probably got messed with by either the Windows 10 installation or by another one-click-root-solution tool. Btw, Kingo and 1-click root didn't work. Root Genius had multiple levels of malware/exploit alerts so didn't manage to finish.

I installed the MediaTek VCOM driver found here: http://www.magicdriver.com/driver4214-ver_1.1123.0.html

I had to follow these steps to get the drivers installed (Win10 blocked installation because the INF isn't signed):

Hold the shift key while clicking on Restart

Select Troubleshoot > Advanced Options > Startup Settings > Restart

After Restart select option 7.

[Miscellaneous Android Development] cyclon1978:
Kernel will come first ;)

Can anyone help? Kernel runs fine but compass is just gone - acer support is informed, i assume kernel is not right for my device (plus version)

--- UPDATE ---

- kernel runs fine, compass works, may only work on e380 plus version, has to be tested on different devices

- performance equal to stock kernel, so there is much potential to increase performance...

All on github.com/cyclon1978

Gesendet von meinem E380 mit Tapatalk
[Miscellaneous Android Development] cyclon1978:
First custom kernel ;)

... for E3 DUO PLUS tested only, so handle with care (should work on all E3 dual sim models)

ORIGINAL KERNEL for rollback:

http://d-h.st/wnV

UNSECURE Original Kernel (for ROM/Kernel devs, adb root access on bootup)

http://d-h.st/Pkh

FIRST CUSTOM KITKAT KERNEL: LEAN KERNEL 3.6

http://d-h.st/TOT

Changes of the kernel

- removed debugging crap

- removed debugging features (remote debugging, etc.)

- some fixes from mediatek official kernel, some fixes from google

- unsecure

and the best: performance increase - not much, but measurable with antutu

No new features for now.

Sources: https://github.com/cyclon1978/e380_kk_kernel/tree/upstream-merge

ignore the other branches and the trunk

PLEASE TEST AND REPORT BACK:

- is compass working on e380 DUO (not PLUS, there it works fine) ?

- for USERS who can UNBRICK: is it working on SINGLE SIM version?

- any problems?

- any suggestions?

Instructions:

- make sure you have a clockworkmod backup

- make sure you're on KITKAT ;)

- make sure you have a clockworkmod backup

- make sure you have not the single SIM version (or have a backup ready)

- make sure you have a clockworkmod backup

- download original kernel for rollback (you can also flush the FixPack-B file from Kitkat rom to roll back)

- make sure you have a clockworkmod backup

- download testkernel and flash with CWM

If anything goes wrong make a clockworkmod restore or flush your original kitkat rom
[Miscellaneous Android Development] paugustin:
Hi cyclon1978, I flashed your kernel on my E3 duo and it works like a charm. It booted straight up and I have not seen any issue so far and compass works fine.

Thanks a lot for your work :)
[Miscellaneous Android Development] freec1:
I have tested the new custom kernel on my originally SINGLE SIM E3, which is flashed with RC18 DUAL SIM ROM:

- Succesfull install via CWM, no problems yet.

- Compass is working after calibration. Tested in GPS Status APK.

- Tiny little improvement in Antutu. 15710 -> 15770 points.

Would it be possible to build an overclockable kernel? I mean, to reach MT6589T's 1508 MHz?

Many thanks for the efforts! :good:
[Miscellaneous Android Development] cyclon1978:
Great, so my kernel works on all devices.

Thanks for testing and feedback!

Overclock is a.t.m. not possible, according to other kernel devs for mt6589. Undervolt is easy, so i might start with that.

Undervolt kernel for Kitkat:

http://d-h.st/XoT4

Only a slight undervolt. As tested by other users it should work on all E3 variants.

Redefined following voltages:

1.20V (0x50) -> 1.15 V (0x48) @ 1,21 GHz

1.15V (0x48) -> 1.1125 V (0x42) @ 988 MHz

1.05V (0x38) -> 1.025 V (0x34) @ 754 MHz

0.95V (0x28) -> 0,9375 V (0x26) @ 497,25 MHz

Damn, i forgot changing Deep Sleep voltage ;)

Here it is:

http://d-h.st/wrO

additional lowered DEEP SLEEP

0.85V (0x18) -> 0,8375 V (0x16) DEEP SLEEP

Have fun!
