Can anybody provide the recovery.img.old taken from /data/data/com.interphaze.AcerRecoveryInstaller after installation of CWM from device with Acer_A500_1.016.05_COM_GEN1.
Check your version in About tablet > Build number.
AFAIK ... there has only been 1 stock recovery...
so there is no need for a rom number specific recovery.img
you can reflash the USA recovery found in the Acer Recovery Installer program and you will have the stock recovery
unless you are doing something else ( adb pushing individual files...etc )... ignore my answer
thanks. i am worried that i would ot get the OTA update if i am on the CWM recovery.
Code:
KRT16O Factory Image available in Downloads section (below)
KRT16O OTA (flo/WiFi) available in Downloads section (below)
As first mentioned by mandrsn1 in this post KRT16O "KitKat" is rolling out now.
I did not want to hijack that thread, but wanted to have a simple continuously updated first post that summarizes experiences and consolidates resources like OTA URLs, Factory Image flashing, etc.
You will soon be seeing comments from folks about how KRT16O affects the remaining Multi-touch and Random freeze/reboot issues on google product forums:
Google Nexus 7 product forum
KRT16O touchscreen experiences (near the end of thread)
KRT16O touchscreen experiences (2nd thread)
Mixed improvement with WiFi turned on and Bluetooth keyboards
pil-gss wakelock issue appears fixed
If you need to refer to the old JSS15R thread, it is here.
Initial impressions
Magnetic smart wake when wifi lost or deep sleeps appears to be fixed
Fix is in 4.01 bootloader - not necessary to flash 4.4 KitKat ROM (thx meekrawb)
Some bluetooth keyboard improvements
GPS/pil-gss wakelock issues appears to be fixed
New touchscreen software.
Mixed results, will likely depend on screen, some fixed, some not, improvement from JSS15R
ghost touches with aligned fingers mostly gone
stuck touches seem to be gone or greatly reduced
may still have missed touches
may still have slight jitters with aligned finger dragging
Does NOT include GEL (Google Experience Launcher)
install extracted N5 GEL and new Google Search if you want the new experience (thx jxr94)
use Nova Launcher if you want transparent status bars
Root can be installed in the same ways as 4.3
If you use NRT (Nexus Root Toolkit) follow this procedure (thx ruggie0)
Logistics (only for people trying to downgrade or mix/match rom/kernels)
You cannot "dirty" flash from 4.4 rom/kernel back to 4.3 rom/kernel, you'll need to wipe data/factory reset
4.3 kernels will not boot 4.4 rom
New FLO-04.01 bootloader.
New boot animation, sounds, icons.
New Easter Egg (thx magnumlove)
settings->about tablet->android version (rapidly tap 4 times)
Tap "K" a few times to make it spin, then see the final prize
New ART (Android Run Time) replacement for Dalvik VM
Enable using settings->developer options->select runtime
Apps should be odexed (stock is odexed)
First boot will take a while (possibly 15+ minutes)
New cloud/network print options
The new tap and pay setting only shows up if you already have NFC enabled. (thx albundy2010)
To get tap and pay working you need to get the N5 version of Wallet (thx ruggie0)
Quick benchmark1, benchmark2 of 4.4 and stock Dalvik (thx Vanillalite)

Change summary:
JSS15R(4.3_r2.3)->KRT16O(4.4_r1.1) AOSP - TBD
Bootloader version: FLO-04.01
Android version: 4.4
Build/ROM version: KRT16O

Mini guides:
adb sideload (install OTA using stock recovery, no need to unlock, preserves user data)
flashing factory images (factory image restore, must be unlocked, option to preserve or wipe user data)
restore stock recovery (if you've installed custom recovery and want to go back to stock)
installing OTA-compatible root/SuperSU (will install SuperSU and fix so that it works with OTAs)
entering safe mode, bootloader, stock recovery (button press sequence can be tricky for fallen android)
Universal ADB drivers (use these if you have trouble with adb recognizing device)

Very Nice! I appreciate you taking the time to put this together and explaining things in detail as always! I now see why Nexus was always the way to go!
I installed this using the nexus root toolkit and it was successful. Appears TWRP is still installed as it used TWRP to install the zip. Will continue to do things to see what works and what doesn't.
Edit - Shutdown and chose to boot to recovery mode, got an android and red exclamation mark. Trying to see if I can reinstall Twrp now.
Finally! Thanks:good:

If you install the SuperSU update.zip immediately (prior to reboot) after you install the KRT160 update.zip, you will preserve root and preserve TWRP.
Initial impressions
New FLO-04.01 bootloader.
New boot animation.
New touchscreen software.

There is new touchscreen software included with this release.
Time will tell how it affects the various screens out there.
On the unit I'm testing on, the ghost touches when aligning fingers are pretty much gone. However there are still missed touches and slight jitter when sliding with fingers aligned. As with previous releases, best to let it settle in. Some problem might go away or other problems might show up.

1.69 should be fine. 1.55 works fine also. Only 1.51 and earlier have issues. There was a 1.6x release that had a placeholder update.zip from the author, but that is probably fixed by now.
thx sfhub for all that you've done.
system installed and is now rebooting. optimizing apps screen now.
I have also booted with ts-unlock prior to install... lets see how the new touch software works

My update fails becaus audio_effects.conf has been modified. Could someone please send me the audo_effects.conf file from stock 4.3 please?
Can someone please post here stock recovery.img for OPT im now on TWRP but i want to install H2OS OTA normally.
Thank you so much
You may have chosen to keep the twrp recovery on your device from beeing overwritten by the stock recovery. This is done in twrp by renameing the "/bin/recovery.sh" (afaik).
Before installation OTA update checks for all checksums of files it will patch. So you will not only need the stock recover but at least to replace the recovery.sh with the original one.
Much easier way is to flash 2.0.2 full (not the OTA!), flash 2.1 OTA, flash SU and reboot in one session from twrp . I have done this and it worked without a problem.
Just make sure your battery is fully charged before
I'm getting an updated binary error. Started getting it in TWRP after flashing a custom kernel. Could you post your stock recovery? Or the stock kernel? (preferably the latter I suppose)
I've tried digging into the full 2.0.1 and 2.1 ROMs to find them, but I can't track them down...
Yes,i need the stock recovery
Well I need stock recovery because of hydrogen OS hope someone have it..
All you need is recovery paparapapa ahahahah
I managed somehow to have back stock recovery
When i flashed TWRP and then Gapps for Hydrogen OS it asked me to stop stock recovery to flash or something so i press dont stop, and voila im back on stock recovery

Guys, I need some help. I need to flash the stock kernel and recovery in order to update OTA to b381 (when I try to install it it goes into Revolution Recovery and the installation fails), but I can't find it anywhere... I tried to flash the ones in the b381 update but I had problems unlocking the phone since the code was not recognised, and had to bypass it with adb. Now I'm back to Revolution Recovery and Elite Kernel V4, what could have been the problem? The kernel or the recovery? Anyway, could anyone give me a link to the b371 stock boot.img and recovery.img? My internet connection sucks and I can't dowload the whole firmware to extract the images (I probably deleted the backups I had made before changing recovery and kernel, yes, I'm dumb).
