Installing custom ROM on D855 - G3 Q&A, Help & Troubleshooting

Hi,
Now I'm running stock v30c rooted by king root and hacer permissivo(one of the method available on xda). I've flashed twrp by autorec.
My question is:
Should I know something before flashing custom rom? I read somewhere that some of roms need v21c modem, and other have no information about it. But I'm not sure if I should flashing this.
Basically I'm thinking right now about custom stock based roms.
One more, I see that some roms supporting CTT(AFAIK it's something about keep the phone cooled, am I right?). Is it supported by every kernel? Including stock one?
I'm coming from G2 and there were quite easier with everything .
Thanks for every answer.

If you are planning to flash stock based roms you don't need to do anything else including flashing the baseband. Only aosp based roms need 21C baseband. So if you flash a aosp based rom remember to flash 21C along with it.
The ctt mod works on most kernels including stock but you don't necessarily need to use it until when you feel uncomfortable temperature.

[Q] Stock google roms

Sorry if this is a noob question but I did quite a bit of searching and could not find anything.
Is it possible to install stock google roms on a DZ? I would really like to install the latest version then have it update itself by OTA. My phone is rooted and currently running Cyanogen Mod 7.1.
Thanks!
Id stick with cm7 from my personal experience its close to stock android Rome and it runs remarkably well

Yes, it is possible to run stock android roms on a DZ, there are several different variants out there right now. Just for example there's virtuous g-lite (look in the dev section or on virtuous' homepage) which is currently on version 2.3.5 I believe. A more up-to-date rom seems to be this one: 2.3.7 (please read the op, some issues still remain).
Though, as far as I know, you will not be able to receive OTAs as these are pushed to your phone by your carrier. If you want to receive OTAs on a DZ you will have to revert back to a stock sense rom.
Any ROM that works on the G2 works on the Desire Z (as long as you are rooted and S-Off, which you obviously are if you are on CM7). So if you want, just go to the Developement section and you will find pre-rooted versions of the G2 AOSP ("stock Google") ROMs. But make sure the ROM is pre-rooted. If you install an "official" ROM that is not pre-rooted, you will lose root, and need to go through the whole process again.

[Q] SGH T999 and Roms.

I had recently obtained a s3 its a T-mobile, its running 4.1.2, with the T999UVDMD5 baseband. I rooted it, flashed xposed(haha the only thing XD). Well, reading about/friends have said there was trouble with the 4.3 update so I decided to stay on 4.1.2.
However, now I've decided to flash a custom rom, and I have noticed the different labels(D2lte, D2tmo, D2usa) and I had read from http://forum.xda-developers.com/showthread.php?t=1736477 "As of right now, the roms for your S3 are not meant to be used on other S3 variants" .
I have a few questions:
1.There was a baseband update, should I update it? If so, how exactly?
2.Would it be wise to flash a D2lte on This T-mobile device? I was looking at Resurrectionhttp://forum.xda-developers.com/showthread.php?t=2692481(originally waiting on cm11 but.. Yeah lol)
3.Looking at KitKat rooms, which ones could I flash?
4.Would it be safe, if I did flash a 4.4.2 to restore a nandroid backup of my fresh rooted stock 4.1.2.
5.Lastly, what kernel would you say use?(Sorry to ask, curiosity as to which i could flash)
I appreciate taking your time to answer my questions and have a good day!
1) custom recovery.. There are zips available to flash
2) d2lte covers all d2 devices so its safe
3)Any on the development threads
4) Yes
5) like on 3, you can flash any kernel in the development threads, experiment and see which one works the best for you!

To answer your questions:
1. You do not need to update your firmware - I'm still on MD5. Modems, however, can be flashed separately from firmware.
2. You can flash d2lte ROMs on this phone as it's all one unified build for US SGS3 variants. (I.e. T-Mobile/AT&T/Sprint/Verizon SGS3 is now all built under d2lte).
3. As far as which KK ROM to flash...just try them all out and see which ones you like the best. Each ROM has different features - see which one is right for you.
4. If you don't update your firmware, then yes. (FYI, flashing a custom KK ROM does not update your firmware. However, if you flash one of the 4.3 root66 files that has firmware included, then it will update your firmware).
5. Again, try it out. It's hard to say which ROM/kernel combination will work best. I suggest you read the forums to see what people think of them.
Hope that helps.

No problem, and i forgot to say but the only time you might need to update modem is if you flash a 4.3 touchwiz ROM, other than that its not really needed unless you want to experiment and see if one gives you better results
Sent from my SGH-M919 using Tapatalk
Oh, and one more thing: DO NOT flash a ROM that is for the international version of the SGS3 (i9300). It will, most definitely, brick your phone.
Don't know if you knew that or not...just wanted to make sure.

New here Looking for guidance on rooting and stable roms

New here Looking for guidance on rooting and stable roms
Rooting?
CF-Auto Root. Sprints NIE works on KK NK2 and LP OB7.
TWRP2 for recovery. Search TRLTE and choose Sprint version.
Stable ROMs. Check android dev section. As stable as any of them can get, its all up to the users on how they use their device.

Absolutely yes. If you flash a stock touchwiz rom then all original apps & features work just like original out of the box. If you flash a custom Cyanogen mod rom or other AOSP rom, then expect issues as these type of roms do not include all of the original samsung features, apps, etc. I'm assuming you want to remain on the stock Sprint Samsung rom so visit this thread and flash one of those stock roms first. But before you begin, you will need to read up on how to root your phone and flash the TWRP recovery. You must flash a custom recovery before you can flash a stock or custom rom. Just look around in the development forums and you will find all the information you need.
tx_dbs_tx, I'm in the same boat w/ 4.4 currently installed.
From what little I've read I'm thinking 5.0 might be a wait (reports of memory leak & battery issues) in hopes that 5.1 will be a better option as I don't have time to fight with those kind of issues right now.
My plan was to root 4.4 and stay there for the next few(?) months.
Am I misinformed?
Thanks!
Its been a fewyrs since i last rooted a device ( Evo4gLTE) and Im having issues trying to root my Note 4. Installed Lollipop only because I found multiple sources saying it can be rooted with lollipop, but everytime i try to use autoroot , which i got from this forum, Odin regognizes but wont flash when i hit start. Should I go back to KK and try again?? Maybe im doing something wrong but I watched videos and re read the tutorials and no luck. Ive checked and double checked im using the right md5 file . Help??

Thank you I rooted. I used Cm12 seems not to be as many roms on here as I am accustomed to seeing been using htc for my last 2 phones. Thanks for the insight.

Can l flash european .kdz on korean model?

Hello, I've recently bought a LG G3 Korean model F400s . I successfully rooted, install recovery and then went for the latest build of xposed modules.
So, now that I have some "freedom", is it possible to flash an European .kdz on my device?I say European because they are similar on specs apart from the extra ram for the Korean model.
It could also be an US .kdz if it's working...anything but Korean. I would like stock .kdz in any case.
I'm willing to try anything really and not afraid to brick it.
Hi,
No, you can't flash a EU KDZ on your device.
I'll recommended to find a custom Rom suitable for your device.
I think Cloudy had an specific Rom suitable for your device.
Regards
Thanks for your reply. Could you recommend a Rom based on stock heavily. A stock Rom?
CloudyG3, SlickROM, XtraLite
Is it possible to flash one of these and then into it so that I can use my banking app?

Can you explain? Sorry, but your question doesnt make sense..

Apologies, what I meant was can any of the above mentioned roms be installed and then can the rom be unrooted.
The reason I cant have a rooted rom is because my banking app that I regularly use won't run on a rooted device.
I have an F400s and rom updates are few and far between. Their are some niggles with the current official LG rom such as problems with dropped calls, but because it's an F400s I can't exactly ring LG and complain because the phone is an import.
I'd like to run a custom rom that has decent support but I need to be unrooted for my banking app.

Did you try to use Root Cloak to hide root from your banking app?
Otherwise, if you flash the non-rooted ROM you lose root again..
I read some threads a while ago which suggested that the Barclays Mobile Banking rom originally worked with Root Cloak but then didn't answer never versions of the banking app were released.
I might try flashing another Rom and try Root Cloak for myself, but to be honest I don't 'need' root these days to be honest.
Out of the roms mentioned above, is there one in particular which you would recommend?
CloudyG3 is probably the best when starting off as it's the least modified.
SlickROM is the smallest in size so is probably the most optimized.
Though, if you don't care about the camera, BlissPop or Resurrection Remix offer the most customisability & performance..
Thank you for your advice.
Typical though, the thread I'm reading through at the moment isn't one that's on your list. What do you think of XtraLite?
....Under their feature list I'm trying to find out what the 'LTE / 4G Mod' is.
I haven't used it myself..

That doesn't inspire me to use it then. You obviously know a lot more about the current roms than I do hence I'll probably go with Cloudy.
I've rooted and used custom roms from the G1 right up to getting my Nexus 4 but it's just not something I've down with my G3 F400s but I feel like I should having had it for a year now.
Which rom are you running at the moment?
Sent from my LG-F400S using Tapatalk
I think it would be safer to flash Cloudy first, as either XtraLite or SlickROM need a 20P ROM to be flashed first. Can't remember which one tho.
The only downside with Cloudy is that you have to flash the CTT mod after, as its are not built in...
I flashed Cloudy on mine, only received it a week ago via Aliexpress, and it's going great, but will probably try both XtraLite & SlickROM in the next few weeks to check the differences
Happy flashing
I flashed both XtraLite & SlickROM, and must say I prefer XtraLite.
The DPI fits better

No sim with lineage based roms

Hi, i need some advice about this problem, bcz i searched that a lot but i cdnt find anu solution. Any Lineage based roms, like Viperos, Strelka, Ressurection Remix, Aokp rom etc (Any 7.x.x too i guess) doesnt work well on my n7100. Im flashing them and they are booting fine too, But when the screen came on, they says no sim, when i checked about device i dont see any info about modem. But imei is not erasing. Boot loader mj5, modem nd3 (i just changed it mj7 modem but still same) . When i flash stock rom or Hyper rom or any 4.x.x based rom works fine. I cdnt find any solution bcz i tried everything. Anyone can give me an idea about this ? bcz i stuck with 4.4.x roms. Thanks..
Is the phone running the latest by bootloader and modem? Some custom ROMs require a phone that is running the latest version of both.

Yes , found latest ones in here and flashed some time ago.
Did you update the bootloader and modem by flashing the latest stock rom or just the bootloader and modem? Not sure if this would make a difference.

I tried both way. Stock rom and 4.4.x based custom roms works fine. They were working fine with older modem and bootloader too. I tried to flash lineage based custom roms on working stock rom and custom 4.4.x too, w/o wipe. They did same thing, everything works fine just no sim silly right ?
Very strange that the sim is not detected. I don't have a note 2 to try out Lineage.
Did you post your question in the the ROM's thread in the Development Forum? Perhaps someone there could offer some more advice.

Yep its strange, i guess the real problem is those roms doesnt see what modem i have in device, bcz they are not showing that in about device. Thanks anyway, at least you tried to give some ideas
I didnt post my question in the rom's thread, let me try it.
