[Q] Custom ROM for the BLU Dash 4.0???

I have the BLU Dash 4.0 and was wondering if anyone has a custom ROM for it? You really cant find anything about it online except on how to root it. The root process was in Spanish but Google Translate will help. Can someone take a look into it please?.
Thank you,

BLU Dash 4.0 Update
I posted the update to 4.0.4 for the BLU Dash 4.0 on the GSM Arena site.
Its running stock android and a lot of the lag is gone.

Download the update I posted on rapid-share
{**rapidshare**.com/files/21...20130521.zip}
(just remove the asterix)
Then follow these instructions, to get to recovery mode I don't know if your phone will be the same; you could always try.
1. Drag the update zip folder to your sd card from your computer.
2. after its on the sd card turn off your phone then
3. hold the power button and the volume down button until you get to the recovery screen.
4. select apply update from sd card then when everything is done installing turn off your device one more time and hold the power and volume button and select factory reset.
if you dont do a factory reset after you install the update then the google play store and anything from google wont work.
so make sure you do a factory reset after the update is done.
Hope that works

Found this thread from GSM Arena and applied the update. Thank you flickpiston for posting. It's a start in getting these phones some dev love.
With that said, about 24h have passed since flashing the update and this ROM is not much better than the original that shipped. I still experience frequent FCs, freezes requiring battery pulls, and battery drain. But hey, at least Google Play Services finally installs like it's supposed to.
Unfortunately, this ROM still has BLU's hands all over it considering there are some dialogs in Engrish just like the factory ROM.
I rooted using another guide translated from Brazilian Portuguese and applied the V6 Supercharger and it has somewhat helped with the lag. I'm going back and forth between the 512 balanced and aggressive settings.
Let's hope we can get a real recovery on this phone soon. And a proper ICS/JB port.

I found out that the XOLO A500 is extremely identical to the BLU Dash 4.0 and they have a CWM recovery that i tried and it worked when i flashed it, but when i turn off the device and try to go into recovery a second time it takes me into the stock recovery instead of CWM recovery. I don't know why it does that

Yeah, going by the specs it seems that the Dash 4.0 is a rebadged Xolo A500.
On another note, I'm keeping my fingers crossed that I have finally tamed the lagging and crashiness of this ROM using zepplinrox's V6 supercharger and KAK scripts. Specifically I switched back to the 512HP balanced settings, enabled the Nitro Lag Nullifier, fixed permissions, and wiped the dalvik cache. The KAK script has everything enabled except for I/O scheduling since I don't want to risk bootlooping without a proper nandroid.
Finally, consider downloading No Frills or some other CPU manager. For some reason the cfq scheduler is the default; I switched it to noop. Also you have the choice of using the interactive governor; this also cuts down on lag at the cost of more battery.

Thanks for the info it really does help. Till now i didnt know about supercharger or KAK scripts. I see improvements . I think the best thing to do right now till the development starts on this phone is to try and find compatible phone that already have developments for them and see if they work, because a custom rom would be nice.

Thank you for your conduct I downloaded your rom but I downloaded from dev-host host because the host Rapidshare very glimmering. I think some friends in a thread for my phone in my country have contacted with some people who also using BLU Dash 4.0 and get the rom from them. That's maybe you, guy I also don't know . I will try update your rom later.
Back to the main subject, as I know, your phone(BLu dash 4.0), my phone (Q-smart S20), Xolo 500, Cherry Burst S280 and Gsmart R1, they are running on 3.0.21-perf Kernel Version and the same hardware like: ram, cpu, os,....., so I think they can use the rom of each other, I have tried with all but the rom of Gsmart R1 does not detect SDcard on my phone, others run well. And now i am using this rom of blue dash 4.0 and satisfied it. In forum in my country, we have a thread with collective rom as i told, if you want to try those roms, i can share. :fingers-crossed: Sorry for my bad English.

Something went wrong when I had tried to update this rom. My friend is trying researching more. In this zip pack, we found that it has many files *.enc, it doesn't like any zip packs which we have flashed.

I am happy to report that I have finally stabilized this ROM to the best possible degree. Scratch that, no I didn't. But the following HAS cut the lag. Forgive me if I repeat myself from previous posts but here are the steps I took in hopes that others can duplicate and confirm:
1. Root using this guide and use Google Translate. You will need the Android SDK, the script in the OP, and the Qualcomm driver linked further down in the thread.
2. Install Busybox from Google Play.
3. Optional: Install Koush's Superuser as SuperSU has been bad news in my experience especially if you wipe caches.
4. Grab the latest Supercharger script. You will need to carefully follow the instructions. You MUST patch services.jar as explained in the thread. I suggest using the balanced settings for 512 MB but of course you're free to use any of the 512 options. You should also try using the Nitro Lag Nullifier.
5. Optional: Grab the Kickass Kernelizer script. DO NOT include I/O tweaks.
Caveats:
TiBu freezes the phone if you try to backup the system apps. Backup your user apps and data. I'm still trying to find a way around this.

DUDE
HEY MAN could you make a CUSTOM ROM AND UPLOAD, because its difficult to me to do all that you said... i want to eliminate the lag

No, guy, I also don't know about that difference so I ask you.
About your rom, I have just update it successfully via Blu's recovery, not success on my phone's recovery, are you using other recovery, guy? I really like this rom, have you tried installing the Gsmart Rio R1's rom? I like both but prefer to Blu.

UMI X1s - Official ROM, Custom ROM and other related stuff

Hi,
I'm a proud owner of a UMI X1s...anybody out there who wants to share information related to this phone?
I a found a custom rom to experiment with:
http://www.needrom.com/phone-roms/umi/umi-x1s/
ROM Android 4.2.1, Based on ROM Official UMI X1S Version: UMI X1S 20130520-220931
After some minor adjustments (Faster GPS to set the correct continent/region) and adding a keyboard app as input method (only Chinese from the beginning) everything seems to work fine...no crash and very stable...will continue testing and probably switch to this ROM http://www.needrom.com/mobile/umi-x1s-3/ . Does anybody know other custom ROM´s.
Known issues/problems:
- Custom recovery is Chinese (English would be great!)
- I´m not sure if GPS is reliable: sometimes fast fix…sometimes not
- Performance (Apex) could be a little bit more smooth (e.g unlock screen)
- WLAN signal/reach is ok but could a little bit stronger
What really impressed me:
- Design is cool, nice display, good responsiveness, good quality, gyro sensor
What I don’t / I have to get used to:
- No LED, the buttons (home, return, config) are not completely illuminated (only the stripes below them),
- back button sometimes seems to be lazy (does not react as fast or good as the other buttons)
Kind regards,
Floris

I also have an x1s.
It's not that the back button is lazy. I've noticed (and others too) that the real physical back button is slightly to the left of the back symbol printed on the case. Just touch there and it reacts as quickly as the other buttons.
About the GPS, I've also noticed the "now fast, now slow" behaviour, but first, you may need to set it up. One suggestion: go to Google Play Store and look for "Faster GPS". It's an app that creates a custom gps.conf file, based on the continent and region you choose. Since x1s comes rooted by default, you can use it right away, and it improves GPS performance.
Then, in order to fine tune the GPS, you need to access Engineer Mode. The best way to do it is from Mobileuncle Tools app. After entering Engineer Mode, go to the location tab and then YGPS. Go to information and click "Full", then "Cold" and then "AGPS restart". You should get a fix in a short time (unless you're indoors or have little coverage).
Anyway, I've tried Tomtom, Navfree and Sygic, and the latter was the one that performed best.

I have a problem, yet no one could give me a solution:
I can't get into/reach the CWM recovery: only the umi screen is visible whatever I try to do. Firstly I took out the battery to move on, then realised that the recovery may be running in the background cause when I press the power button it reboots, as it's the first item in the recovery to be accepted with the power button. I tried to set back/reinstall the original recovery but it's the same with that. What could be the solution?

Your problem is not unknown. Looks like the latest UMI update, from May 28, is not good and causes that behaviour. The only solution is to install an older update. I did that, and then used one of the roms from Needrom. The update I used is from May 20 and can be downloaded here:
http://ul.to/q69qn8ui
Then go here and choose a rom which suits your needs: http://www.needrom.com/phone-roms/umi/umi-x1s/

CM ROM: Not that I know of.

Nice to know that there are some other UMI X1s usere out there
For now I´m quite happy with this ROM http://www.needrom.com/mobile/umi-x1s-3/ ...anyone here tried the newer one?
I discovered that GPS comes quite fast I use YGPS (Mobile Uncle Tools)...even if I use the cold method...but if I use google maps it does not work or the fix takes very long :-/

Does anyone know, how to get GPS working?
In YGPS it says Status: UNAVAILABLE and blinking TTFF: Counting.
I modified gps.conf with FasterGPS to my region.
I have EPO and A-GPS enabled and I am using this ROM http://www.needrom.com/mobile/umi-x1s-3/

First, make sure you try it outdoors, 'cause indoors it may take a lot longer to fix a location, or not work at all.
In YGPS, the best way to do it is:
1) Go to the information tab and click "AGPS restart".
2) Click "Full"
3) Go to satellites tab and wait for the GPS to fix the location
4) After you get a fix, return to the information tab and click "Hot"
5) Close YGPS, and open your favorite GPS navigation software or GPS Status app, and see how fast the phone can fix the location. Now you should be able to get a fix in a few minutes maximum.

Thanks, it really helped me. Now GPS is working.

Double tap feature

Hi guys,
is there a way to have the double tap feature to wake up the phone?
I mean without install a new rom. Maybe installing a kernel that support the stock rom.
Thanks

install blue spark kernel stock version

Thanks a lot for the reply. Could you give me extra informazions about that kernel?
Where I can find it and if it is possibile to restore the original kernel in the case I don't like this one.
Thanks you
EDIT:
I found the kernel. But int the last post the developer says that the kernel will not be updated anymore. Do you advise to install anyway?

Interested in this as well, haven't found specific info on installing the "blue spark kernel stock version" on the Moto G 2015 though?
EDIT - ah ok it's here http://forum.xda-developers.com/2015-moto-g/orig-development/kernel-t3207597 - going to read up!
EDIT2 - ah bit confused on what needs to be done to flash the kernel...(is it dt.img ?) TWRP needed (I have it since I rooted) ? Also someone mentions going back to stock kernel if need be here http://forum.xda-developers.com/201...ent/kernel-t3207597/post63208808#post63208808 but I can't say it's very clear to me

If you want to install the blu_spark kernel you have to download a zip file from this page. If you come from example from the stock rom you have to download "blu_spark_r92-stock-5.1.1_osprey_1562e7b.zip". To flash the zip you have to go in recovery mode and install it.
About restoring stock kernel as far as I read from the message you linked you have to:
-First backup the boot partition from TWRP and save it somewhere
-Do something...
-If you want restore the stock kernel you have to restore the boot partition you have saved in the first step (do it always from TWRP)

Thanks, it's a bit more clear now, are you going to give that kernel a try? On top of the double tap I'd be interested in getting improved battery life as well.

Well, I'm quite uncertain.
First option: install a custom kernel
Pros:
Install a single zip file instead of flash a custom ROM (losing all data)
Maintain the stock ROM
Cons:
Development for blu_spark kernel is abandoned (like the developer said in the last post of the topic). Yeah, you would have the double tap feature but have a kernel with no support. An option could be install this kernel and as soon as possible change it with a new one with active support. What do you think about?
The other kernel (squid kernel) misses this features (double tap to wake up)
Second option: install a custom ROM (e.g. Cyanogenmod 13)
Pros:
Very good ROM (from my own experience with other devices like Nexus 7 and Huawei)
If I'm not mistaken Cyanogenmod has the double tap features as a default feature
Cons:
Losing all data flashing the new ROM (actually not a very problem)
Losing the stock ROM (this is a not very problem too)

Smart creen on off is the solution!
It's available on play store. No root needed.

Thanks for the reply.
How about the drain battery of an app (such as Smart Screen Off) compared to a built in kernel feature?

None of the apps I've seen works well with double tapping as they want you to double tap on the proximity sensor. One option I've seen that works ok is "waving" if you set it to 3 quick waves. Not as nice as double topping.

It seems that a new kernel has appeared. It has the double tap to wake and is currently supported.
There is only a small problem: it doesn't support the stock ROM, but the CM13 yes.

Not hw feature. Can use more battery

Thanks for the heads up, no go for stock 5.1.1 though
Did you ever try the other kernel now abandoned? That one worked with stock apparently.

How to activare Knock On?

Hello, i reality want to activate the LG function Knock on on my new motorola moto g 3.
How I can enable it? I'm on 5.1.1 stock lollipop because I've read that it works better than android 6, I read too that this function need an custom kernel, I prefer to keep my stock rom, is really working amazing, are a way to use this option without touch the kernel?
I want the real knock on, that works with the screen off like LG phones, I've tried some apps but they keep the screen on or the proximity sensor on and this drains the battery obviously, so that's not what I'm looking for, my device is rooted.
Thanks.

You heard right, this requires a custom kernel that has DT2W (Double Tap to Wake) compiled into the kernel, then you have to use a tool like Kernel Aduitor to enable it on each boot since even kernels that have this feature usually have it disabled by default.
Not that this will increase drain battery anywhere from 1% to 3% per hour (usually on the lower end of that range though, depends on usage)

Thanks for the full answer! Well looks very well 1 or 3% of battery for that option, you can say to me what kernel is recommended for this?

AGNi or Explosion kernel are the only two I know with DT2W still enabled... FireKernel used to have it, but it was removed a few versions ago.
Make sure to backup in TWRP before flashing a kernel, if you want to switch kernels after flashing a custom one to try something different, restore the boot partition, and boot fully before flashing a different custom kernel.

Really thank you for your help, now I have another question, do you know how to activate the option on camerafv5 for manual focus? It is possible? I've read that will work with the new camera2api included on lollipop but I dunno how's that.

Pretty sure the G3 doesn't support Camera API2
