Hello Guyyz, its good to be part of community which has such a active development going on, we already have sufficient number of kernels and roms and many are still to come (all credits to devs) .
But it seems littlebit time consuming and painfull to backup , test (different roms) and restore. It would be a great help if any knowledgeable DEV can port DUAL BOOT PATCHER or MULTIROM for our phone. Flashing could be more fun.
THANKS IN ADVANCE.
yes multiboot will be a fun

HI all , i lunched this thread after weeks of googling and usless search for a new stock or custom rom to update my phone (samsung sgh-i857 doubletime) it's a dual screen phone with querty built-in keyboard it's from at&t and it is stuck on android 2.2.2, i'm very sad that they and after years from lunching it didn't back it up with a single soft update -_- ... and i know that there are users who bought this phone like me and seek help.. i know that it's not this easy but if you are a devloper help us by creating a custom rom for it ....if you are a user of this phone please support this thread by commenting so we can get an update for it :good: ps: i attached informations for it's cpu
Hello good sir, I like you am a noobish Doubletime user who is struggling to update it to Gingerbread. So far I have been somewhat able to use the Cyanogenmod source code and I have built a CWM Recovery for the device but that seems to have hard bricked it... I ordered a new one off ebay for $15 and I'm ready to start cooking. You have my support!
Just an update.
I have a plan I have on how to get this runnin.
1. Port CWM to the DoubleTime through Cyanogemod 6.
2. Get a working version of Cyanogenmod 6 working on the DoubleTime to hopefully free up some space.
3. Find if Gingerbread can run on Froyos kernel.
From there I'll either be building a GingerBread compatable kernel or Cyanogenmod 7 depending on compatability. Any advice or help would be very appreciated.
Being new to ROM building I'm a little lost and hesitant on flashing things but here's what I know so far.
The DoubleTime uses a Qualcomm MSM7230 same as the HTC Vision. I forked it's Github respiratory and I'll be using it as a base as recommended by the Cyanogenmod porting guide.
The partitions sizes (as a accurately as I can estimate them) are:
/cache=21.05MB
/data=176.65MB
/system=194.38MB
I may need to know the recovery partition size but I'm not sure how to find that out.
I have the recovery.img and the boot.img as well as the zImage. So as soon as the repo sync is done I'll be on my way.
I'm back again today with somewhat mixed news, I can find most of the partitions and their names (I've learned a lot today) but I can not seem to find the boot, recovery or ramdisk partitions. I'm already boggled by the what seems to be unconventional naming setup for partitions. Put all of my "notes" in a text docement in the attachments section. Any help with this is very appertiated. I can type and post anything into the ADB shell you need me too.
I'm beginning to feel like I'm talking to myself, I probably am...
Upon reading forum rules and such it has come to my attension that this is the wrong forum for this kind of thread, So I have made a new thread in the Miscellaneous Android Developement Forum that will hopefully be more useful at getting more proffesional and opinionated help.

Hi Everybody
after some weeks Trying developing ROM's and Kernels i almost Give up... the kernel developing to MTK SoC is too much different compared to qualcomm SoC's (To me at least...) after compile more than 10 kernels to Run at my phone i only get Bluetooth and Radio FM not working with random reboots annoying frequently... but a real modifications to get this phone more smooth usage fail every time...(if you only compile the original source kernel it will run exactly like original kernel...)
I'm too n0#b alone to get everything running at developing process(kernel or ROM dev.).. at qualcomm phones(Xperia Acro S and Xperia L), i get more things running correctly with much more help from others Developers... but not released anything because it will be more from the same as others releases...
so if anyone here have more knowledge about that developing process things i have the Kernel Source and ROM platform to our phone...
---
i already try make CM12.1 run too.. but don't boot =#.. and if get work soon will be too much unstable to release, like my kernels =#
i will try port CM12.1 from @fire855 using that tutorial
the other possibility is try make compile the CM12.1 using our sources with modification from this ROM
but i will need help to make it compile right =#
so.. i will like have a discussion about that process with you guys... if anyone have some experience to help our phone have more custom's things to don't be locked with Original stuff/performance only.. if anyone have a useful guide, video or tutorial to compile anything to MTK SoC's it will be great too :highfive:
I appreciate your effort! I don't know much about MTK personally, but there is a thread on 4pda about porting CM 12.1 to MTK processors.

Click to expand...
Click to collapse
already started try port CM12.1 ... but will not work too much things... almost every sensor will not work because that cross-firmwareOS port (CM Modules Drivers have a different compilation process =#) what i can do is try upgrade our source kernel using other MT6592 Sources to can compile the CM12 to our device... but again i will need find Module Updates drivers(blob) from other phones sources... =#
and my status with that right know is fixing a lot of errors while i compiling the kernel... i don't reach the inHouse ROM Compilation to than can get more Errors on logs to fix to release a simple Almost "stable" rom to how want test if it works properly to everyone... but don't push me to get that finished.. i work everyday and when i have time i try my best to develop that :highfive:
and release a unstable ROM/kernel is a wrong because maybe can brick someone phone because my errors (ramdisk modifications, and partition table map when installing the rom)... or we can wait BLU release the Lollipop with Hope because on twitter( @ UKkazam) tell me about no lollipop updates to this phone =#
i Tweeted to [@ KazamUK] asking they about lollipop updates and receive two replays... One say about newer updates to fix bugs on OS but not about lollipop and other saying "unfortunately, not upgrades to newer Android versions will be released"... otherwise [@ BLU_Products] Replay this "Please stay tuned on our social media for future updates, thanks!"... so... we have a faith about BLU brings Lollipop to our device? i don't have sure but with lucky it will happens :highfive:
...
and the porting CM12.1 ROM don't worked with me... bootloop =# and CatLog is extremely confuse =#
Kernel source link not working
I have an opportunity to make a PORT CM12 for BLU VIVO AIR in two days. A neighbor of mine bought a VIVO AIR and I will do whatever is necessary to get the ROM on the device.
I helped the BLU VIVO IV the users to have CM12. But as the device was not mine, so I could not fix some bugs. In the same epoch I talked to a BVA User and helped the kernel issue. He had given me feedback in relation to not have phone signal and not be able to replace the IMEI. But as I had no time, and the phone in my hands, the CM12 ROM stood with him.
Currently, it is quite possible that after CM12 MT6592 to be 95% stable in most of these devices Socs, the VIVO AIR may also have.
Once I have the device in hands, I'll let you guys know if CM12 can be available for all users VIVO AIR.
But if anyone know a actually already exist a ROM CM12 for VIVO AIR and clones.... Let me know...??
That would be awesome and I'm sure as me a lot of users are going to be happy about it

Hey Guys ,
I am making this thread to share you guys the method to Port MTK roms to your device .I have tested this on mt65xx series and it works FINE .
Many of my friends stopped mtk development and i think its time for new guys to start their work to keep the community growing on XDA apart from fb groups. :highfive:
IMPORTANT :TRY THIS ONLY IF YOU KNOW HOW TO RECOVER FROM BOOTLOOP AND BRICKS.And Ofcourse Try these at Your Own risks beacuse No one will Take Any Responsibility if Anything Happens to You Or Your Device or If you fail your Exams or If you Lost your Job or whatever
FOR PORTING BOOT.IMG YOU NEED ANDROID KITCHEN SOFTWARE , I WILL ALSO GUIDE YOU HOW TO INSTALL IT So Lets Begin.
1.Install android kitchen On windows PC :angel:
(For porting boot.img ,skip this if you are porting same kind of rom so you can copy the orginal boot without modifying!, read bottom for more info)
Youtube LInk In case if you need : https://www.youtube.com/watch?v=4SZpOluF7lg&t=9s
2.PORTING BOOT.IMG
(For porting boot.img ,skip this if you are porting same kind of rom so you can copy the orginal boot without modifying!, read bottom for more info)

There are more custom roms for our Athene , please someone develop multirom. I'm not a developer I'm not able to understand basics about software development but there are more developers with skills but nobody interested in developing multirom. Why? Some lower end devices had multirom support but our Athene ?
I use dual boot patcher
If you use multirom which is better and easier than dualboot patcher. There is no requirement for patching, you can flash any ROM/zip file easily without patching. Patching a zip for one ROM which is not be flashable to other ROMs ,eg: you must patch gapps for all ROMs ,which is boring and take extra space in storage.
Hi everyone,
I was very excite when I saw this post on TRWP site: https://twrp.me/site/update/2020/12/31/twrp-3.5.0-released.html since it would add the so much missed support for native android 10 devices like my 1+7tp mclaren, but to build this twrp you need an android device specific for 7tp mclaren I belive (similar to the ones found in https://github.com/TeamWin/?q=android_device_oneplus) (the android 10 branch)
Are there any guides on how to do this? I'm more than willing to give it a go and share it back if i manage to get it working.
My whole point in getting a OnePlus device was that I could dual boot (it would be really nice to be able to dual boot nethunter for work since I constantly need to do simple security assessments on the fly. Having that possibility on my mobile would be a huge time saver for me)
Any help will be greatly appreciated!
And congratulations to all on this forum. It's always great to see the coding communities at work!

do we have any TWRP version possible to stall ROMs ? I tried 3.4.0.2 and 3.4.0.12, none of them works
