Wow Awesome :) going to flash r6 tonight after being on r4 for a week.

We are incredibly lucky to have Shreps developing the latest OS for A700. Thanks Shreps
[Acer Iconia A700 and A510] peter_altherr:
hi folks,

today i just thought i give it a try and installed the latest cm12.1 build 08072015 coming from latest nightly cm11. i did also install the nano gapps as the bigger gapps packages won't fit in /system. well, all i get is my tablet stuck in acer boot logo screen. recovery used for flashing is latest cwm 6.0.5.1. like to mention i am used to flash android devices for several years so no panic on my side :) the second try was formatting manually /system /data /boot partition from the advanced cwm recovery menu and reflashing the rom + gapps. but... same game as before. just the acer boot logo. of course i did a nandroid backup before so as i mentioned no panic here but i really like to try out this rom.

any hints are very welcome, greetings

peter

ps: when i used the format data/factory reset menu after having flashed this rom for the first time the device rebooted without any warning and i had to use shortkeys to enter recovery mode again.

---------- Post added at 03:22 AM ---------- Previous post was at 03:01 AM ----------

well, problem resolved by using the wipe /data /data/media menu. don't ask me why. i thought i did this before :)
[Acer Iconia A700 and A510] Shreps:
Nice

Don't hesitate to feedback on how it's running :)

PS : I'm building a new version, with all the CM updates.

Hi Peter, you are right , my tablet doesn't show any satellite too. I didn't realized, because I never use the tablet for navgate. [MENTION=4493088]Shreps[/MENTION]: is there a Chance to get GPS running? Thanks for your effords!

Hello

I have the A700

I install the rom. I am on the screen acer.

I can't go to the recovery (Carliv Touch Recovery 3.3 for A700).

And the USB MTP driver is not working after the flash with this rom..
[Acer Iconia A700 and A510] cybero2912:
THX a lot for the new version!!

no problems found so far
[Acer Iconia A700 and A510] Shreps:
You should post in Q&A for this kind of issue.

Plus, you're mixing things, Recovery - ROM and MTP when Android is running are not related.

So make sure you have all the requirements (JB bootloader, unlocked, ...)

And follow the right procedure (factory reset mandatory if you where not on CM 12..1)
[Acer Iconia A700 and A510] Shreps:
I will try to look at this on my A510, but I'm not sure it's the same issue as A700. Will see :)
[Acer Iconia A700 and A510] Sterist:
my a700 has no issue locking GPS

performance is at an all time low though, with stability at an all time high lol
[Acer Iconia A700 and A510] Impromark:
Okay! After months of not selling the A700, I'd like to try out this ROM... First thign I'd liek to do is update the recovery, but I can't seem to flash it for some reason. I tried to plug it in per this:

http://xdaforums.com/showthread.php?t=1984566

But it can't recognize the device.. Nothing happens and I get a <waiting for device> . Have I missed a step? The USB drivers are installed. Please let me know, thanks!

[Acer Iconia A700 and A510] Sterist:
if you're rooted already, you can flash the recovery directly using Flashify from Google Play. download the CTR-- something recovery. you can find it somewhere in this forum section or at [MENTION=4493088]Shreps[/MENTION] website acer.shreps.fr it'll be towards the bottom in a700 section

must use that recovery with this rom if I remember correctly. you'll need to flash nano-gapps at first, but can debloat a little to make room and flash micro-gapps after that, which includes more essentials, so while you're downloading em, be sure to grab both at once for convenience

note that the a700 has some performance issues on lollipop. it's faster with CM11 kitkat (though still slow as this tab has always been). this rom (lollipop) is still highly functional (95%? 98%?) and stable.
[Acer Iconia A700 and A510] Cowboy_Henk:
I'm trying to install cyanogenmod mod 12.1 on my parent's A700 but I can't seem to get it work.

The tablet has an unlocked jellybean bootloader.

I got cwm recovery installed first.

I wiped data /factory reset.

I flashed latest Cyanogenmod 12.1 (20150904)

I flashed the latest nano paranoid gapps for 5.1

I wiped cache and Dalvik.

I then rebooted. Cwm asks to restore root first but I say no for now (I tried yes but it's the same result)

Result:

The tablet boots to unanimated acer logo. It reboots to the same logo after 20 seconds or so.

See my screenshots
[Acer Iconia A700 and A510] Sterist:
again, you need to be on that CTR recovery and flash it from there.
[Acer Iconia A700 and A510] Cowboy_Henk:
Ok thanks but if it's that important Shreps should have mentioned it in the Opening post that CTR is necessary. The requirements he mentioned were

An unlocked Bootloader - JB Version

An updated CWM (6.0.5.0+), CTR, or TWRP (2.7+) recovery

I chose CWM ...

But I did what you asked. I went to acer.shreps.fr

I flashed recovery-CTR_3.3-A700_Shreps.img

I did a wipe/factory reset

I flashed cm-12.1-20150904-UNOFFICIAL-a700

I flashed pa_gapps-modular-nano-5.1-20150315-signed.zip

I wiped cache and dalvik

I rebooted.

I stays stuck on acer logo, reboots, acer logo, reboots,...
[Acer Iconia A700 and A510] Sterist:
are you sure you have the a700 WiFi-only and not the cell version a701, or a510?

also, try formatting system and data (not internal storage) then do install again without gapps -- format dalvik and cache after that then reboot
[Acer Iconia A700 and A510] Cowboy_Henk:
Yes it's the silver a700, it's written on the side.

I always did a "all wipe" in ctr recovery.

But I successfully flashed CM11 latest snapshot from the cyanogenmod site and latest snapshot recovery from the same site. Everything works smooth, I think my parents will be happy with it.

Thanks otherwise.
[Acer Iconia A700 and A510] grimmse:
First of all, thank you for this great ROM. I had no problems upgrading from CM11 to CM12.1.

Yeah, thats a big issue with this device. 2D rendering and IO perform really bad.

If you can sacrifice the brilliantly high dpi for rendering performance you can change the resolution to e.g. 1440x900 180dpi. Everything is almost the same size but way faster. Scaling animations down to zero in the developer options helps too.
[Acer Iconia A700 and A510] pinkyring:
Stuck at Acer boot logo

Hi can someone point out what I'm missing? I've tried to install the ROM per instructions, but my a700 is now stuck at the acer boot logo screen whenever it is turned on.

Did a wipe data factory reset

Used CWM 6.0.4.4 and installed the rom and micro gapps.

I tried 3 times but the same result. Really wanted to try this new rom out on my sluggish a700 running CM4.4.4 nightly.

Help!
[Acer Iconia A700 and A510] Sterist:
scroll up, only a couple posts, and you will have your answer ;)

note that performance is better on kitkat. stability is better on lollipop
[Acer Iconia A700 and A510] pinkyring:
Yikes! I seemed to have mucked up my a700 even more. Before I saw your post Sterist, I tried to update CWM by enabling "update cyanogen recovery" in the developer options as suggested by Shreps in a different post. I installed a CM4.4.4 nightly update for the sake of it, and CWM appears to have been updated to 6.0.5.1 (from 6.0.4.4), but now I can't get to recovery at all. I get the following error when I try to manually get to recovery and it reboots back to the Acer logo:

CWM-based recovery v6.0.5.1

Finding update package...

E:unknown volume for path [SDCARD:update.zip]

E:can't mount SDCARD:update.zip

Installation aborted.

Rebooting...

I can't get my pc to recognize the tablet either to reflash via adb, and Flashify can't do it either (it will say flash successful, but will reboot to the old CM4.4.4 Rom). I'm assuming your post suggested that I use CTR to flash the rom, but now I can't install CTR nor can I get to CWM...

Help x2!
[Acer Iconia A700 and A510] pinkyring:
Update on my adventures: I'm able to get back to recovery by reinstalling CWM6.0.4.4 via flashify and going back to the 4.4.4 Nightly ROM. Then tried using TWRP 2.7.1.0 recovery to flash the 5.1.2 ROM but got the same stuck at acer logo result as with CWM6.0.4.4. Then tried to install CTR3.3 via flashify but got the same "unknown volume for path..." issue as above.

I still can't get my computer to recognize the tablet so I can't use adb. Confirmed that the usb driver is correctly installed through a 2nd a700 tablet, so it's something wrong with the 1st a700 that the computer won't recognize.

I have an ICS bootloader, but I don't know if that's the issue...and I don't know how to update to a JB bootloader.
[Acer Iconia A700 and A510] Shreps:
Has mentionned in FP, this ROM Requires a JB unlocked Bootloader.
[Acer Iconia A700 and A510] pinkyring:

Use this images:

or

Flashing bootloader 021 patched for root JB 4.1.2

fastboot flash boot boot021patched.img
[Acer Iconia A700 and A510] pinkyring:
Thanks KoFe86. I will give the boot021patched.img a try. Can I use Flashify to flash the bootloader? As mentioned in my earlier post, I cannot get my computer to detect the a700 so I can't use fastboot via adb.

Also, will flashing the bootloader wipe my existing ROM and data? Or will it just update the bootloader from ICS to JB and leave everything else?
[Acer Iconia A700 and A510] KoFe86:
Why? Whot os? This for Windows:

Acer usb drivers - http://global-download.acer.com/GDF... A&Step3=A700&OS=A09&LC=en&BC=ACER&SC=EMEA_27

it is very important to be able to flashing with the PC. Because if you kill the device , restore it will be possible only with the PC
[Acer Iconia A700 and A510] pinkyring:
I tried using adb/fastboot, but when I use the commands in your post: "fastboot flash boot boot021patched.img" I get stuck at the <waiting for device>. Using "adb devices", it does show that the tablet is connected, so I don't know what's going on.

I also tried to flash the boot image via Flashify, but after rebooting the tablet, the boot screen still shows "ICS-MR1...(unlock mode)" at the top left of the screen and it would hang at the cyanogenmod logo with the arrow going around in circles.

I read in the forum that installing the AconiaN2.6 rom also gives me the option of upgrading to the JB bootloader, but all the links to the rom are broken...very frustrated trying to install...grrr....
[Acer Iconia A700 and A510] KoFe86:
Fastboot commands work only in fastboot mode!

Enter:

adb reboot-bootloader

Then your device reboot you see Bootloader Version ICS-MR1-a055314 (Unlock Mode) (this is fastboot mode)

Enter:

fastboot flash boot boot021patched.img

Then enter:

fastboot reboot

You see: Bootloader Version JB :good:
[Acer Iconia A700 and A510] pinkyring:
When I enter "adb reboot-bootloader" in the command prompt window (Windows 7 PC), the tablet rebooted. Then when I saw the bootloader version screen (ICS-MR1...) I entered the other command (fastboot flash boot boot021patched.img), but the same <waiting for device> message shows up and hangs there. After a few seconds, the tablet would go to the cyanogenmod startup screen and start up normally. No JB bootloader... :(
[Acer Iconia A700 and A510] pinkyring:
Anyone have anymore suggestions? I can't understand what I'm doing wrong?
[Acer Iconia A700 and A510] Shreps:
It's adb reboot bootloader

With a space not a dash
[Acer Iconia A700 and A510] KoFe86:
I did not think about it:fingers-crossed:. if the command is not correct , why had the device reboots :confused:
[Acer Iconia A700 and A510] pinkyring:
Tried both "adb reboot boodloader" and "adb reboot-bootloader" commands. Both variants will reboot my a700. When I see the "Bootloader Version ICS-MR1-xxxxx (Unlock Mode)" text on the top of the a700 screen, I enter "fastboot flash boot boot021patched.img" as suggested, but the Windows command prompt will always show "<waiting for device>". The a700 doesn't do anything and after several seconds will reboot normally to the cyanogenmod screen.

Using "adb devices" shows:

List of devices attached

015c7d7a46400208 device

So it does seem that the a700 is recognized. I'm at a loss to understand why fastboot is not working.

You see "Bootloader ICS(UnlockMode): Starting Fastboot" and the device will stop downloading.

Check command: fastboot devices

If you see lake "adb devices" shows or else, it's good. If nothing, try changing USB cables or ports on your computer.

If this does not help , I do not know that your device
[Acer Iconia A700 and A510] pinkyring:
Can you clarify this step: As soon as the tablet vibrates, let go [power] and play [lock]? What is play [lock]?

When I press [vol-] and [power], after the first vibrate, if I get go of the [power] button and keep pressing the [vol-] button, it goes into recovery.
[Acer Iconia A700 and A510] KoFe86:
[Lock] is button that locks-unlocks display (near the volume button)

"Play" is moveing left to right and right to left the button

Button to move the "unlock", before start your device
[Acer Iconia A700 and A510] pinkyring:
Thanks for your explanation KoFe86. That did the trick! I'm finally able to get into fastboot and flash using the .img file:

C:\a700sdk\platform-tools>fastboot flash boot boot021patched.img

sending 'boot' (4364 KB)...

OKAY [ 2.281s]

writing 'boot'...

OKAY [ 2.328s]

finished. total time: 4.615s

C:\a700sdk\platform-tools>fastboot reboot

The problem is that the bootloader still shows the same ICS version after reboot, and the tablet is now stuck at the cyanogenmod logo in a continuous loop.

Sorry I don't understand how flashing a new recovery will help. I'm trying to upgrade to the JB bootloader so I can install this new ROM which according to Shreps, requires JB. I have installed CTR before and tried to install the 5.1.1 ROM, but it did not work.

okay, so I have been reading on how to upgrade my A700 to the newest android OS but am getting super confused. is their someone who has done this effectively that could do a step by step writeup from start to finish. ie what software/patches/roms required before I start mucking up my tablet. no cutting corners or leaving out anything. just a real easy how-to-guide on this update. whoever does this will be a God send.

I did a system wipe, tried to install the ROM image and get errors, tried to do the google apps just to see what would happen, and the error said there wasn't enough space available. There's 21 gigs of space open on the main storage.

So at this point, If i try to start it stops at unlocked mode for JB bootloader, I can get to recovery - can someone point in the direction to go, to try and get it up and running again?

Thanks !!

ZigZag kernel is a heavily customized kernel based on the cm12.1 nightly sources for yuphoria. It aims to provide extreme battery life, insane performance and great efficiency.

​

Features:

Compiled with SaberMod 6.0 toolchain for faster performance and battery

Added -Ofast optimization flag for increased performance(code size increased by 3mb)

Implemented BFS(The Brain F*** Scheduler)(More notes on BFS below)

Added KCAL control by savoca

Added Thermal control(thanks franciscofranco)

Added powersuspend for faster wakeup time and deep sleep for long time thus improving battery

Added many TCP congestion controls. Westwood is default.

Many many tweaks for responsiveness, performance and battery life.

What is BFS?

BFS is an alternative CPU scheduler to the stock kernel's CFS. BFS features a simple single-runqueue O(n) earliest virtual deadline first design. There is no need for excessive balancing to achieve fariness on multiple runqueues, nor is there a need for strict NICE values. For more information, check out following links:
