[samsung i857(doubletime)]ROM devlopers and users of this phone

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.

[Q] Just a few questions!

Hi fellow G2 users!
Got my G2 a few days ago (I know I'm about a year late) but this phone seems awesome. Model is D802.
I did a lot of reading before doing anything and so far - I am on stock LG rom, rooted, installed TWRP with autorec, flashed a volume mod and installed xposed with g2 tweaksbox. So far I have nothing to complain about.
Anyway, now come the questions - my previous phone was a sensation, and to have that fully ready to flash, it required unlocking the bootloader, S-OFF, radio flashing and root.
1. Is there anything else I need to do here? This is my main question. I did a lot of reading before posting this or doing anything to my phone. I only do something once Im completely sure I know how.
2. I've read about flashing modems of some sort and came across this link - xda wont let me post links for the 1st 10 posts... Its a site like codefi.re/autoprime
Can someone please tell me what the 4 different versions of the D802 files are?
3. Any recommended ROMS/kernels that are absolutely brilliant? I know that all devs make great roms but with specifically battery life, STABILITY, and all the LG features (like knock on and the new message reply box thing and quickmemo, etc) I have heard a lot about Pardus. Might try that out soon if I dont get any other recommendations.
4. I read about Jishnu's camera mod. The links have been deleted from his thread. Is it okay to ask if anyone has a backup? I would like to try it if possible.
5. I read about Viper Sound Mod. Is there an updated method of installing this on stock rom? The thread I found seemed outdated and half the links were invalid

Nobody?

Depends on what you want. Have you researched aosp roms? All the things you looked up are fine. Tweaks for a ton will help enrich its use but to change to a complete different operating system is what you should try out if you want to see something different. Modems usually come with the rom. Make sure you flash the correct variant for your device.

I see a pattern emerging - lack of guides

Hello! This will be a quick post about how it was good earlier and how it can be better today, so please, stay with me.
I've been using Sony's for a while now, starting with small and cute Sony Ericsson k510i, then k550i, then wt19i (LWW), and then Xperia SP. My "flashing career" started after I've lost warranty on my k510. At that time there wasn't a lot you can do to your phone - there were several official firmwares, various customization options, and a lot of custom patches. No competition, one latest official firmware, a big library of patches that you could port to your device, if someone didn't do it already. The only competing area were a lot of graphical patches, but you could compile them together on your phone. Like today, if you were doing something wrong with your phone - you'll get a brick and it's your fault. But for every device there was an instruction, a beautifully crafted instruction on what to do and how to do everything, step by step. Almost every thread included a complete set of links to get you started. If you needed to flash a customisation after installing something, there would be a link on how to flash custom right there.
Today I have my XSP and try to do something to it. So I open one link (non-sticky, needed to bookmark it), see a lot of ROMs, part of which are no longer maintained. Finally open one of them based on performance rating, and see that it needs some kernel. So I go to kernel list, and see that it can't be flashed without recovery. What recovery? One specific recovery, because another one can't flash it. Now how do I flash recovery in the first place? I need a manual for that. Now I go to kernel and ROM page and see that no manual is available for them, too. So I open main device page and don't see any manual, so I open a sticky thread. And guess what? I don't see manual there. And that's when I start a new thread, type my problem in, and see a non-sticky thread with last post made 2nd of May 2015, and no pages link to that thread at all.
Is that how it goes this days? A newbie comes in, spends whole evening, opens 10 tabs, and still can't find anything relevant? I think we need to do something with this, revisit old threads, compile a new one-for-all guide, or at least a list of guides. And stick it, so people can actually see it. Otherwise there will be small closed community of those who already can develop and flash, and all the others who either got brick or is afraid to get a brick. Thanks.
---
UPD: And then I see that the kernel which I almost decided to flash is closed and all developers migrated to another one. I'm talking about tangerine and helium. Again, no info in the first post. And main developer openly says to users of his work - if it didn't work for you, don't use it. What's wrong with you people...

I'm deeply sorry if I offended somebody with my previous post. I'm happy that you guys do such amazing things with this 3 year phone. But damn, FULL INSTALLATION took about 10 minutes, counting PC reboot into linuxes to get fastboot working. In case someone struggles like me, use CyanogenMod instruction to get to Cyanogen Recovery; download TWRP Recovery, ROM of choice and GApps of choice; place all three ZIPs onto your sdcard; go to recovery, flash TWRP, reboot into TWRP (by pressing volume rockers while loading), do Wipe - Factory Wipe, flash ROM, flash GApps, reboot to normal. Wait for about 5 minutes (black screen is normal, there will be dots flying after a minute or so to keep you entertained).

Yes, It's that simple nowadays, so why bothering typing so much? I was in that situation with my SP, too, but if the are so many answers to these questions and so many threads... "You have to read" is the answer! A lot! It's for your own good, trust me. Now I can do anything I want with my phone with nohow! So a little reading and searching here and there is just positive experience for you. Don't complain, the people here ( well a part of them) are hardcore coders or themers or whatever. You can't just ask them to tell you all the stuff. If want help I'm always available.

Thank you for linking to my very dusty and lonely Flash ROM guide hahaha
No you didn't offend anyone at all. The guides are actually there, like how to use Flashtool, how to unlock bootloader, how to flash recovery and everything, it is just that they are buried deep with time as the development goes. The thread are there, in the General section and are awaiting to be searched. Though some are outdated, some are not and you can benefit from there.
Some searching will normally do, but if it didn't, just ask in the threads, someone will probably answer to you!
I always have my eyes on the General and Q&A subforums of the Xperia SP, and I will usually respond to a help-able problems. So if you have any problems, feel free to post in the Q&A subforum, and if not me, someone will help you. If there are nobody, don't feel offended. Maybe people don't know what to help or suggest (but lets just hope that is not what it will be )
About recovery, PhilZ and CWM is way outdated, and its time for everyone to make TWRP as a standard as it is a still updated recovery. Cyanogen Recovery in my opinion is crap as there are far too less feature plus, it enforce on signed flashable zips.
About the thread on Tangerine, the developer said dont use if it doesn't work is because of the norm of the Kernel. The kernel is made by using an AnyKernel template, hence render support for almost all Lollipop ROMs. Since ROMs can be updated and all ROMs have different sources, a simple change in the system part can render Tangerine unsupported, and the developer cannot do anything (definitely his choice, please respect that) to only fix the problem on one ROM which could possibly break support for the majority of the ROMs! This also appplies to Helium. Therefore, his words of "dont user it if it doesn't work" has a meaning, and it is not something to degrade new users and so.

Thanks for the answers and offering help, happily I was able to install my ROM of choice and it still works flawlessly, I was even able to squeeze 20 battery days from my old XSP.
Thinking about it, I start to understand why that dev answered like that. I was a python dev in the past and know how one feature can kill two others. Just in my head there is one current linux kernel, and all things that are developed should work with that particular kernel. Kernel comes before OS, if you will. Isn't it the case with ROMs and droid kernels?
About TWRP and reading: I honestly did read a lot of info before doing something, because it's my only phone these days. But it's so hard to find information on whether something is deprecated or not. As a new user, you wouldn't just google "is this deprecated and no longer used?", because that search will not provide any info. That is why during that evening and following morning I lost count of how many times I just shaked my head asking which recovery/kernel should I use and how do I install it? Latest being the easy one, because I already found TechnoSparks thread by that time.
In case anybody is interested, I installed Candy 5 on default kernel. But I still don't know if installing android 5 on a kernel used with android 4.2 was a good idea. It went well, however.

pro elite 3 x722- help, please

Hello! I bought elite 3 x722 and it comes with android 6- 5.8.020S shop rom., at first I didnt notice it because it comes with playstore and some other google features. I'm happy with phone but It doesnt allow me to upgrade at least for android 7 and the keyboard for messages is only in chinese or english tho' it has many languages to work with the phone. I've been reading you guys and I have watched some videos on youtube warning about Not Use Shop Roms, about this stealing our passwords thro' the apps etc. and Im scared. The thing is: apparently the official rom 5.9.026s comes with bugs, I've read lot of complains about people installing roms and the phone bricked then. My knowlodgment about phones is 0 so the tecnical language is being a pain in the ass for me to understand.. Want to kindly ask you what Rom for x722 Elite should I install. And how. And in a simple language language because Im a big noob
ps: sorry for my bad english

I'm on the 20s shop ROM from Banggood right now. I don't have an issue. As for privacy concerns, I can see where you're coming from. But the most you should be worried about is adware. You can uninstall LeEco bloatware apps via adb. See this post: https://forum.xda-developers.com/showpost.php?p=75670844&postcount=2
You should be more afraid of the NSA than some random Chinese companies that resell phones, lmao
As for installing a custom Nougat ROM, you can do that. Head over to the LeEco x722 development section. Hit the URL in my signature to learn how to unlock the bootloader and flash a custom ROM. Since you're on 20s, you'll be able to unlock the bootloader and flash a custom ROM easily. Read the sticky thread about the x722 in this forum before proceeding.
Stay away from official or stock 26s if you're interested in rooting your phone. Modded or custom 26s is fine.
Finally, this thread shouldn't exist because it asks some very basic questions. You should have read through this entire forum before making it. Please don't create threads without doing your research first. If you try that in other sub-forums, your threads will be removed or ignored.

thanks! I know these were dumb questions. I have read other topics trust me, but in the end I had the same doubts: 'so which rom should I install? which one is best?' because I always read stuff that worries me. But I dont like the shop rom. I even only get between 1.8- 2.1G out of 4G

Unused RAM is wasted RAM. That's what anyone who knows remotely anything about computers will tell you. And smartphones are just tiny computers. If you're experiencing app refreshes (going into an app restarts it) then it's probably the LeEco bloatware apps needlessly hogging memory in the background.
There's a phone code you can try in the stock LeEco dialer to turn off memory optimization or something like that. https://www.google.ca/amp/s/forum.x...-to-past-notification-issue-eui-t3497530/amp/
As for which ROMs is the best, that's up to you to research for yourself.

Changing the ROM where to start?

My guarantee on my phone has run out. I have a Galaxy S10+ exynos with one ui 4.1. Where can I start to change the rom and root my phone? Can you recommend me an up to date and safe guide?

Google could have done all of this for you.

Do you know how many results you will get if you ask google? Not all of them will be valid or up-to-date and it's hard to pick one.

I really don't understand what you're saying. I rooted my first phone thanks to articles on google. They usually don't even have to be up to date. Plus your phone is relavitely new compared to what I had.

Anyways, first look for a guide to unlock your bootloader, that's the first step.
Next, learn how to flash twrp onto your device.
Lastly learn how to flash custom roms onto your device via twrp. Custom roms can be found in your device's dev forum here on xda.
You'll need a pc, the right drivers, minimal adb and fastboot (or odin), and the required files (twrp, custom rom, gapps)

Also, you've posted this into the wrong subforum. This subforum is for rom development, it's where devs post roms. If you want to ask a question or need help then ask in the Q/A subforum.
