Installation Keeps Aborting?

Hello, I am by no means a power user, but have managed to successfully root devices and install custom ROMs in the past. However, I am having trouble with this one and am looking for some guidance please.

My current Sero 7 Pro is rooted and I installed the custom Root/ROM built by XBOXEXPERT. Everything has been working fine and I recently heard about your KITKAT Custom ROM and so tried to install it but with out success. I provided info about my device and my install steps. Any idea where I am going wrong?

Device: Sero 7 Pro 8 GB (USA)

Android Version: 4.2.1

Kernel Version: 3.1.10

Build Number: P756.6.02.20.00

Clockwork Mod Installed

Custom Root/ROM: XBOXEXPERT's ROM

Install Steps:

1) Downloaded your file from this thread (the most recent one I could find where everything is fixed/working)

2) From Recovery mode, I wiped data, wiped cache, and wiped Dalvik

3) Selected option to install ROM from external SD and selected your zip file

4) Everything looks good and an install starts as expected....shortly after an error message happens and it says the install was aborted

5) I then restore to my backup and I am basically where I was prior to trying to install your KitKat custom ROM.

Any guidance would be much appreciated. Thanks.

I spent some time earlier today looking at the WiFi-Display (Miracast) code (it's scattered all over the place), so when I browsed what kensuke was offering with his gazillion patches, it didn't look too alien. I'll try to make sense of it and see if I can integrate it with my AOSP build. Using his stuff as a roadmap looks a lot easier than striking out into the unknown as I had expected I'd have to do. Thanks for the info!

You need to install one of the three recoveries in the first post of this thread before you can install taktiK or davepmer's ROM.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] DellXCD35user:
One more question about the recoveries you noted

Thank you for your response/help. I found the reference to the recoveries you mentioned (listed them below).

However, I am still trying to understand a bit more. I already have a Recovery Mode installed (either I use the Power On + Volume Down Key or ROM Manager to turn it on/enter the mode).

Are you saying that even though I already have this Recovery Mode, I should install the CWM (swipe + selinux enabled) since I have CWM installed? And if so, my other related question is if something goes wrong again during my KitKat custom ROM install, will this impact my current ROM back-up/restore (since it was created using my current recovery I am wondering if after installing the new recovery it may prevent me from restoring?).

RECOVERIES:

CWM (swipe + selinux enabled) Recovery: http://jellytime.googlecode.com/file...e-sero7pro.zip

Twrp recovery (selinux enabled): http://jellytime.googlecode.com/file...e-sero7pro.zip

Twrp themed (selinux enabled): http://jellytime.googlecode.com/file...e-sero7pro.zip
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] lichan:
You need a recovery that is selinux enabled. The original one wasn't. You can flash all ROMs with the new ones. To be safe, flash the recovery, do a new backup of your current XBoxExpert or DoPa 2.0 ROM and then flash a new ROM.

You might want to check the "rastakat" ROM source code (AOSP based). I'm running rastakat on my N7 (2012), and it looks like Miracast is built in, but I have nothing to check it with.

How to Flash the CWM (swipe + selinux enabled) file and Recovery mode no longer work?

OK so I now get that I have to flash one of the files so that I have the Selinux enabled version. I thought to try the CWM (swipe + selinux enabled) file. Trouble is I was not sure how to actually flash it? I downloaded the file and it appears as a zip. In the past I have only flashed a ROM in zip format (I simply used ROM manager to "Install ROM from SD Card"). I noticed ROM Manager had an option to install or upgrade CWM. But when I followed the prompts, it did not give me a choice to update from a file. Instead it went to a server and now it seems I screwed up my Recovery.

What I mean is....I can power on and my current ROM comes up and works fine. However, if I try to boot into Recovery.....it tries to and gets stuck displaying "Recovery" in green and never changing and just hangs. If I power off and on the tablet boots fine and works. So it seems I can no longer boot into Recovery mode.

Any idea how to fix my Recovery mode issue?
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] Talon65442:
You should still be able to use ADB and FastBoot to to flash the recovery image (extract from zip to your PC).

Or it may be simpler to just use an app like Flashify (for root users).

Free version should do ya just fine.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] DellXCD35user:
Thank You Sir!

Sir, if you sensed a disturbance in the Force coming out of North New Jersey, it was me praising you for your outstanding help. I used Flashify as you noted and resolved the Recovery issue and now just successfully installed KitKat. Many many thanks!
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] Gazoo119:
I tried several equalizers from the play store and none of them worked. I think this is "normal" since sound effects don't work using the stock player.

I could not get V4A to work but I had my bluetooth headset connected through the whole install process. Could that be the problem? Every time I opened V4A a message popped up to install the driver. BTW I installed the first driver and tried the other 2 drivers but the other 2 caused all kinds of havoc.

Can you or someone else tell me which of the three drivers I am supposed to use? As I recall I used the first one in dopa and it worked just fine. Anything else I need to know?

I am still lovin the rom and have put it through quite a few paces with zero issues. Thanks.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] gberpa:
Try updating V4A. Mine works with Dopa 2.0 w/ over clock. Don't know about randomblame or davepmer ROMs.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] Gazoo119:
Did you notice I was replying to delorespark's post, which I quoted? I am running the AOSP rom delorespark posted..

I also mentioned in my post that I had no problems with V4A when I was using Dopa.

Hopefully someone will help me out that understands my post. But thanks for trying.:)

I wouldn't mind trying rastakat, but I can't seem to find the .zip file. Do you have a URL or can you put up the file you had?
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] chrisdaun:
I could'n't this flashed with the TWRP recovery in the OP. Gave me an updater file missing error.

But I was able to get it to flash with the CWM in the OP and gotta say nice work [MENTION=5094650]dolorespark[/MENTION]!

Once flashed I've had zero problems so far and everything I use on a regular basis works.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] Gazoo119:
Nevermind. Got V4A working. :cool:

Oops...spoke too soon. If anyone can give me step by step instructions to get V4A to work with delorespark's aosp build I would greatly appreciate it.

RastaKat is not yet available for the S7. I'm running it on my Nexus 7. There are several threads on it, but you can start here: Rastakat for grouper.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] jerbear294:
It should be simple to port Rastakat- I believe it's CM11 based, so I can use the same trees I did for PAC. :) When I fix some issues with PAC I can compile Rastakat for you.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] TheLoonyRebel:
That would be amazing. Thank you so much. :D

anyone know how performance and battery life compare between aosp and cm11?

ive been running daves 03/14 cm11 build since it was posted. its been working flawless for me, and not sure i want to swap.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] alex_is_the_1:
I know it probably doesn't help much but I haven't even had it charged up all the way. Plus performance is quite good for me. I don't have a lot of apps installed yet.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] ALD3:
I have installed aosp442-dopa-v0 and it works very well, I was on dopa-v2.

A couple questions,

1. Google maps won't find location, GPS is on

2. Is there a way to set screens up with home in the middle? Only added screens as I installed more apps and home is always far left. Know it's probably my noob with this

Also FYI If anyone wants to use Bright house app-BHTV, you must edit build.prop in device/system/build.prop. It reads>>> ro.build.tags=test-keys and needs to be changed to >>>> ro.build.tags=release-keys

With all the same spacing or BHTV will see a rooted device and shut down. If you already ran BHTV and got Rooted Device.....After changing build.prop, go to apps/BHTV and clear data and reboot. Should work from there.

Thanks [MENTION=5094650]dolorespark[/MENTION]

EDIT: Google maps started working????? All well now!
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] jerbear294:
You can use Xposed GEL Settings to change the default home screen to the middle one.

I'm using the Xposed module Root Cloak to hide the root from BHTV. It works flawlessly.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] ALD3:
Thanks Xposed Gel worked great! Didn't know about Root Cloak either. Good info ?
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] Gazoo119:
Just to expand on this a bit, the first time I tried to use the GPS it didn't work inside the house. It was also a cloudy day out but I thought the problem was with the rom. So I loaded one of those apps that checks the GPS and indicates the satellites....still nothing. Then I remembered when I had this problem before I had to go outside to get the GPS to pick up the satellite signals. So I went outside and within a few minutes all the satellites that the tablet was able to pick up was displayed on the screen.

So just pointing out if the GPS doesn't seem to work indoors, go outside and wait a few minutes....it will work and then should also work indoors from then on.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] davepmer:
New Build, Note: This is a cm-11 Nightly and will require a clean flash from any stable build.

This build has a kernel change, it scores slower on tests but seems faster. It has much better cpu core control than before. It seems to use all cpu speeds now.

The base is not overclocked.

Let me know what you think of the cpu control.

https://www.dropbox.com/s/f1i13iciibopgju/cm-11-20140325-Nightly-m470.zip remember do a clean install.

to over clock flash this over the above build without wiping anything. It should erase all your wifi settings.

https://www.dropbox.com/s/py8x5a0imkwof3o/m470-add-overclock-20140325.zip

If you find overclock is not for you then flash

Hope you have better luck than I am having. I thought I found most of the removed code, but it will not build for me.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] jerbear294:
Is the new kernel pushed to your github?
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] davepmer:
Yes it is.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] jerbear294:
Yeah I just noticed after looking at the cm-11 branch. I'll add the updates into PAC when this build finishes.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] davepmer:
Did you get netflix to work in PAC?
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] jerbear294:
Not yet. I still fail to see why it crashes... Dalvik is the same in PAC and CM11.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] davepmer:
I know, worse most of the other vital systems are the same too.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] jerbear294:
It's strange, the logcat barely told us anything either. :eek:

The build failed, I suspect the ccache- I'm putting your new kernel into PAC now.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] ALD3:
Thanks. I also noticed on stock Sero 7 Pro that GPS seemed weak and got lost when using it for navigation while driving. Was the same on dopa v1&2. Mostly a hardware problem, it would seem.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] dolorespark:
I've got Miracast video working but not audio. The video was pretty easy: I used the patches that seemed appropriate and skipped the rest. The audio is another story: the problem appears to be in either AOSP or our proprietary blobs. It can't find an available "remote_submix" audio device even though its module gets loaded and "r_submix" is configured in audio_policy.conf.

Once I got the video working with my Samsung TV (no compatibility issues at all), I was not impressed. It was OK for fairly static screens but when I tried to watch a video in the stock browser, it was hopeless. The connection to the TV just couldn't keep up. In this case, the WiFi may have been overtaxed trying to receive the video from the internet while transmitting the image to the screen, but I suspect Miracast will still be laggy with local content.

FYI... Most of the code that the author of these patches is trying to restore is either obsolete or ill-advised. When first introduced in JB 4.2.2, Android devices were supposed to be able to both send and receive screen images ("source" and "sink", respectively) but Google abandoned the receive feature (if you look at his screen shots, you'll see why). I'll keep working on the audio issue, but I can't see any reason to try reinstating the receive function.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] a178235:
From reading and my DLNA tests with BubbleUPnP, I didn't expect Miracast to be very good quality for video, and my opinion was that it was barely acceptable. I could not test it for screen casting though, such as games, web browsing, etc. I don't see any reason for receiving content either. I don't see anyone spending a lot of time to make Miracast sending working unless you see some benefits to yourself or other users for web browsing, etc. My kids keep breaking the HDMI cables every now and then, so I though using Miracast would help even if it was lower quality.

Thanks for taking the time to work on Miracast support, I really appreciate it and I'm glad you were able to get it working with you Samsung TV.

---------- Post added at 07:03 PM ---------- Previous post was at 06:57 PM ----------

Actually, I remember that most of the BubbleUPnP was not bad, just some of the AVI files. Perhaps the h264 played fine as it was already in h264 format, but Divx needed to be transcoded, etc. I also have an 802.11ac router, so that might have helped with the bandwidth. I would be willing to test out the ROM if you want to make it available some time and I could do some video testing even though the audio does not work. At least I would know if it works with my dongle.

I'm getting the wifi dropping out and losing wpa key after clean installing this update from stable. I'm using the standard kernel. This didn't happen with stable. Thanks
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] davepmer:
I know wifi goes to sleep with the screen of for any length of time, but I have not had any drops or random reboots and the only time I lost the wpa key was when I flashed the overclock mod, and I designed it to do that to start overclock with a fresh start. You might try flashing the overclock mod and see if it still looses the keys.

However I may not be much help to fixing this as I can not duplicate the problem.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] davepmer:
Well after working great from noon till 2am I have had two SOD in the last 3 minutes. Not sure if beta ROM or kernel mods. I can't really see the kernel mods as runnable threads is an approved kernel mod and found in quite a few kernels. But this is a nightly build and they tend to have bugs. So I will build a stable to find out. Weird seems some how related to charging. But I had it off and on the charger all day with no problem

Not sure why but does seem to be my default cpu quiet governor. swapped back to userspace default and testing.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] lexridge:
I am getting this too. I first tried the test-wifi fix, no good. Then I tried the overclocked kernel too, still no good. Not a huge deal, as I think I am really liking your AOSP build much better anyway. With very few exceptions, it is a really good build.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] davepmer:
But what is driving me crazy is why dont I have the problem. My wifi doesnt drop, it does go to sleep after the screen is off for a while, but after several reboots (manual) it has never forgotten the wpa passwords.

As for the SOD issue, that is even weirder , It happened this morning between 6 am 8 on two different chargers, but worked correctly on the third charger and since 8 I have been unable to get an SOD again. Even on the same two chargers, and with the battery in the same state,

I will make a Stable build since I want to see if that fixes your wifi issues, should nearly identical to the last stable build, since the stable builds wont be updated for a few more days.

Sorry for OT:

Is it possible to access the external SD Card through Windows on your 03/07 build?

In MTP mode the tablet gets detected as Nexus 7 and I can't access it at all. Reinstalling USB driver or installing PDANet driver doesn't fix it.

In PTP I can get ADB and Internal Storage access, but can't browse the contents of the external SD.

If it isn't possible, do your new builds (or AOSP, or anything) fix it?

Thanks for your great work! :good:
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] lexridge:
Your last stable build (3-17) was very good after I applied the wifi fix. The only other problem I had with the last two stable builds was the terrible terrible lag I had on the Swiftkey keyboard. I do not have this problem on the latest CM11 (3-25) or your AOSP ROMs. Weird.

BTW, I have not had the SOD with 3-25 and it has been plugged into a Motorola wall charger for the past 4 hours.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] boonesmi:
i'm still using daves 3/14 build, and i have no problems accessing the internal and external drives. running win7 x64 (it shows up in "my computer" under portable devices as "sero 7 pro")
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] davepmer:
Yeah I have had mine on the same charger it SOD on, for the last 6 hours and it is working??? Like I said it seemed to be time related between 11:00Z and 13:00Z before that and after that I can not even make it do an SOD. During that time, all I had to do was turn off the screen with it plugged in to either of two chargers. But even during that time the 3rd charger would not get an SOD.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] boonesmi:
I much prefer the twrp recovery, but it gives a fail error when trying to install the aosp ROM. An update to the recovery would be cool.

Anyway, I've been using aosp for about an hour. It was probably just a fluke, but a few min ago I was unable to enable WiFi until a reboot. I was one of the lucky ones with zero WiFi problems on Dave's ROMs.

Thanks everyone for all the hard work!!

Since we have been unable to get our own forum here on XDA and we are getting a multiplicity of recoveries, kernels and ROMs with different subversions and tweaks, how about making a new "sticky" thread with a set small number of entries which track the versions of each dev's work. Each dev would start a reply that only they could edit and keep track their work, maybe the more stable versions of ROMs, kernels and recoveries and pointers to the more detailed threads that follow the development. I wouldn't want it to impact the developers' efforts with record keeping but everyone would know where to find the 3/14 version of davepmer's CM11 ROM and which kernels you could apply to it. We in the great unwashed would have to refrain from adding our own posts to the thread to keep it pristine and go to the development threads to make remarks, ask questions,etc.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] davepmer:
Be a wonderful idea, If you want to go ahead and if you want you can give us (RandomBlame, doloresparks, Me and the other devs) a link or give us an email and we can keep you updated.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] jerbear294:
This.

I also think this is a good idea.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] davepmer:
As I promised, here is a cm-11.0 Stable Build. It has a modified Kernel with cpuquiet having another governor. I put it as an option using Trickser MOD. That way if it does cause problems it is not the default. Let me know if the wpa forgetting password problem is gone. It might be something in last nights nightly.

Remember you must clean flash if going from a nightly to a Stable or Stable to a Nightly. You might be able to dirty flash Stable to Stable.

https://www.dropbox.com/s/bo5reo4wc43f9vu/cm-11-20140326-Stable-m470.zip This is not overclocked.

to over clock flash this https://www.dropbox.com/s/wqzbux8r6aium4b/m470-add-overclock-20140326.zip without wiping.

and if overclocking gives you trouble, flash this https://www.dropbox.com/s/73sd9g16ly73ckw/m470-remove-overclock-20140326.zip without wiping.

Warning I designed the add overclock zip to erase wpa settings, in case the settings would get messed up this should clear them.

Two Questions on the AOSP442 ROM

1) I set up the Advanced Power Menu options available in Gravity Box (and also via the Xposed Framework). When I try to soft reboot, each time my WiFi stops working. And not matter how much I toggle turning in on and off, it just won't work. However, if I do a hard reboot there is never a Wi-Fi problem. Just wanted to mention in case I am missing something.

2) I noticed the original 3 Power Save Options (Performance Priority mode, Balanced mode, and Power Save mode, that came with the Sero 7 Pro is no longer available? Previously, with Power Save mode on, I got fantastic battery life and no performance issues. Is there a way to enable this in the AOSP442 ROM?
