Custom roms - Galaxy Tab General

im a bit lost on tablet roms i have droid incredible rooted and custom rom that is easy stuff but trying to find out what roms there are for verizon version of the tab and this mix between gsm and cdma is confusing seems there are more roms avaliable for gsm and the cdma roms dont seem to be complete.
If anyone can suggest a good rom for verizon SGT i dont mind reading but i think atm verizon roms are very limited.
Thanks for any information

This is one of the only one's I've seen. You have to have your EXT4 formatted file system to use it but Boushh has a link to how to do this. There just are not that many currently for VZW tabs.
http://forum.xda-developers.com/showthread.php?t=941749&highlight=verizon

Yep, Boushh's firmware is about your only real option, which isn't a bad thing as he's got pretty much everything covered, ext4 support, 1.4Ghz overclock and VoodooSound support.
The main problem is that the Verizon SGT is a CDMA device and has several hardware differences which means the kernel is not compatible with the more common (?) GSM/WCDMA version.
His firmware is as per CoMtnMan's link, the kernel itself is at http://forum.xda-developers.com/showthread.php?t=941781
You'll need to use Heimdall to flash the kernel first and then flash the firmware. You'll want to boot into the recovery and do a backup to the MicroSD card first in case it all goes wrong, then do a full wipe, reboot into download mode.
Guides are in the links anyway.

[Q] flashing, rooting, kernel, jm, ka??? whats all of that???

hello there
can anyone please explain whats the difference between the firmwares which i read about jmk or jme or or pre rooted or cdma whatever they are
and whats kernel is
everyone just keeps talking about it but i have no idea whats do they mean
im new to all of this so it would be nice if someone can explain that to me
thanks alot guys
Hi,
I'm just a 'newbie' (nob) as well, but can help you with this:
When you root your device you can run some programs that only run on a
rooted Tab; eg, Rootmanager and others.
The terms JMG, JME, JMI, are names of different firmwares developed
by diverent devellopers. Each firmware changes how your device
performes (mostly better than the original firmware).
A rooted firmware is one that (eg Roto's JMI) was rooted by the
develloper and if you install that, you don't have to root yourself. . .
it is already rooted for you.
There are basically 2 types of cell phones: CDMA and GSM. CDMA is supposingly faster than GSM where available. Also, GSM phones use sim cards; CDMA phones do not.
The kernel is the center of each operating system. Don't know to much about that. . . . sorry.
Hope this helps some.

How easy is it to install a custom ROM on the p1000?

I have an LG Optimus One and custom ROMs can't get any easier. It's just root with z4root, install Clockwork recovery with ROM Manager and flash away. I'm not yet familiar with the other aspects of rooting and installing. So I ask how easy is it on this device? I might pick one up soon since it seems to be getting cheaper and cheaper...
It's really simple. Same app to root, then use the Odin program to flash while in download mode. Instructions here.
I'm still a beginner when it comes to Modding and this was a cakewalk.
Sent from my GT-P1000 using XDA
Ok sounds good. But what does GSM and CDMA mean? How would you know what kind of Tab you got (I'm assuming these are hardware related since the roms have only one or the other)? And what does the modem have to do with anything?
I didn't have these terms involved with my O1 so I'm not sure yet what they do... At least I know to avoid the Wifi only p1010 since it isnt as developed for (really important to me).
gsm/cdma is about cellular networks, if you have a simcard slot then your a gsm, cdma is without one, the service company can provide you service without one, its mostly a USA thing, sprint, verizon etc, not sure about Europe,
look at the back of your tab and tell us your model no. i have a p1000t, but this tread states you have a p1000 so i assume you have a gsm one.
sorry if its not too informative.
Practice makes Perfect
All custom ROM providers these days seem to suggest you follow the Overcome Guide. This guide was the one I followed to start with and it is very clear. Go to the teamovercome.net website and look at the guide.
I can do this now from memory, and have used the same method to flash ICS, Hyperdroid, and Overcome.
It's a great guide - flash and enjoy!

[Q] GSM Rom suggestion ???

Hi all,
I just sim unlock my sprint s4 both international and domestic. It come with the NAE modem. while unlcok it, I odin to MDC modem.
I have signal and text on AT&T network on this phone now. ( Phone is not rooted yet, I did edit the build.prop to add ril.sales_code=LOL
ro.csc.sales_code=LOL. I am not sure if not-rooted matters).
Right now I am looking into flashing a rom to use on AT&T network. Lots people suggests Fenny's T-mobile rom. and some suggest SACS CUSTOM ROM
I am not sure which is better if I am using a GSM network.
And If T-mobile roms are better for GSM rom, how could I flash them? Do I need to flash NAE modem back?
Thank you for all of you idea/suggestion.
I just asked pretty much the same question in the following post...
http://forum.xda-developers.com/showthread.php?t=2764201
I think we have to build the roms for the device ourselves, but I was reading about calling issues on unlocked phones so I'm trying to find out what to do as well. Flashing recovery is easy enough, then the rom of course, but getting this right rom zip seems to be a little tricky in our scenario. Not hijacking or anything, but check my thread too in case someone answers on mine first.
BTW, this is the post I was referring to about phone issues with non-stock roms on an unlocked sprint s4...
http://forum.xda-developers.com/showthread.php?t=2539794
Well, it looks like the 100% sure way to get this working is to do the outlined steps in the post linked above to the nightly builds of CM11, which I will link below (notice the spr/att designation at the end of the link)...
http://download.cyanogenmod.org/?device=jfltespr
http://download.cyanogenmod.org/?device=jflteatt
Other way looks to grab a jflteatt labeled rom from the Sprint Android dev subforum, but it looks more hit or miss. I might be way off and overthinking this, but I'm gonna try the mix/match way.
Well, I ended up working this out myself. I grabbed the nightly CM11 spr and att jflte builds, then followed the directions from the post I linked before that showed how to mix the 2 so the Sprint boot.img was in the AT&T build, including changing the updater-script so that the assert line read "jfltespr" in the 3 locations it had "jflteatt", then flashed the jfltespr CWM recovery from Heimdall, used recovery to wipe data/cache/darvik, installed the mixed rom from recovery, then installed the Chronic kernel (blackscreen without this), and the gapps apk for CM11. Once I was done everything worked perfectly, I only had to change the APN to the ATT Phone one for HSPA+. From what I can tell the CDMA portion of the phone is pretty much gone, and it shows the phone model as the AT&T version instead of the Sprint version (ie shows l337 instead of l720). The correct phone number from the SIM is now properly displayed as well. Also, with the Chronic kernel (slight OC) and CM11 the phone is lightning fast and responds instantly. Overall I'm very happy with this. Hope this helps anyone else in the same scenario. BTW, still using MDC modem from Odin flash during the domestic unlock.

SM-N910W8 Custom ROM Help (Rooted and TWRP installed)

Hey XDA I have rooted and installed custom roms on various android devices in the past, and am now working on my Note 4.
I have it rooted and TWRP installed , but am now unsure if I need to flash a different modem or bootloader. I understand that the Canadian variant uses the T-Mobile Roms.
I am looking to install CMRemix http://forum.xda-developers.com/note-4-tmobile/development/rom-cmremix-rom-v2-5-12-23-14-t2981479 which is a T-Mobile Rom.
Will I simply download and flash it or do I need to do extra work first?
Thank you, and I apologize for posting this question. I was slowly going crazy after searching the forum for these things to no avail!
I figured it out. I checked by bootloader and it was up to date. I was having issues with Odin, but after reconnecting the USB cable 6 different times it finally picked up my phone in Downloading mode!
No worries. It seems that the N910W8 is basically the same hardware as the N910T3.
In the same way the Note 3 T-Mobile was the same as the Note 3 Canadian variant.
No need to worry about modems assuming yours is up to date.
Although, I must admit that while CM Roms tend to have interesting features, they lack support for some of the built-in hardware, and the battery life has been inferior in my own experience.
You should check out Temasek's CM versions.
Have fun

Bootloader unlocked, can I use any rom?

So Ive had this Verizon Note 3 since day one. Finally unlocked my bootloader... What are the rules on what I can and can't do now. Can I install any Android rom? Can I only install note 3 roms from any carrier... Can I install only Verizon note 3 roms? Or is it a hybrid... I can install any rom if I replace the firmware and or modem.
I really want something on 7.1 but I'd rather take 6 and have something custom... Fast and responsive.
Thanks community.
You are in luck. :crying:
There's hardly anything to choose from; maybe 3 or 4 ROMs and about the same number of kernels.
AFAIK, there are no Nougat ROMs and only one Marshmallow ROM (AryaMod6.6).
Normally, when a dev ships a "ROM", there are two important pieces: the /system image (what some folks call "the ROM"), and the boot image. The boot image is what some folks erroneously call "the kernel"; but it is really a combination of kernel + ramdisk. The ramdisk has all the scripts in it that the "init" process reads to start up all the low-level daemons and services... as well as the Android UI as well.
The kernel is very tightly tied to the specific hardware in a given handset - both the processor/gpu and all the sensors/leds/peripherals.
So that's the reason you can't just flash any old ROM. In the least bad case, your device wouldn't boot; in the worst bad case the kernel would boot up far enough go off in the weeds and possibly damage some of your hardware.
You might be tempted to think "we'll, what if I find a boot image for the "hltevzw" SM-N900V device... can I flash that after I have flashed 'any old Android ROM'? Won't that take care of things?"
Well, not really. The system library binaries in /system are possibly compiled with instruction-set optimumization tweaks that are only supported by specific CPU and GPU hardware chips. Moreover, other peripheral chips such as GPS have unique "downloadable" vendor firmware in the system image... so again, there's the issue of hardware dependencies of the /system image.
Beyond that, there's carrier-specific "setup and activation" software that differs between ROMs, so even using ROMs that are from a different carrier's version of the exact same handset hardware might not work fully - specifically in the telephony function areas. Everything else might work fine though. For instance if you wanted to use the device as a WiFi-only unit for kid's games etc.
Note BTW that the "International" Note 3 GSM phones are not the same hardware - they use an Exynos processor.
good luck in your quest
Thanks
That was very helpful... Looks like Araya is my best bet. I'll leave jasmine rom to try it.
I was hoping that I could get another note 3 rom on this forum and flash the CDMA modem for networking... But doesn't seem like that's an option.
If I'm still stuck to Verizon Note 3 rom... What is the purpose or benefit of unlocking the bootloader... Was that really just to avoid Odin so I can flash my couple rom choices easier?
I appreciate your time!

I might have very slightly overstated the case for pessimism. There is a "consolidated" Verizon Note 3 Forum which is meant for devs to provide development tools and even ROMs that could potentially be used on devices from more than one carrier. But the world being organized the way it is, that means that you are more likely to find multi-carrier GSM ROMs over there than multi-carrier ROMS which support GSM and oh by the way CDMA and LTE as well.
If you want to fool around over there, I recommend that you proceed with great caution to make sure that the ROMs you choose specifically target Qualcomm MSM8974AB Note 3 handsets, and you should read the developer notes very carefully to see whether you need to flash an "hltevzw" kernel separately. If the dev does not mention "supports hltevzw" or "supports N900V" (for example here) you might be taking chances with your hardware.
I suppose it is possible that the radios are 100% "software defined" in the sense of which bands they can support. Maybe you can get what you want by simply flashing the desired carrier's "modem" firmware, but I have never done that so I can't say for certain whether that works or you are risking a brick (or hardware damage) by doing that. I simply don't know (e.g.) if the chips and antennas in a T-mo version of the Note 3 are identical or different from a Verizon Note 3's hardware

Well, for one - having a custom recovery allows you to make backups - even if you never change ROMs
People don't think of backups as being "sexy", but they allow you something which is really valuable: freedom to mess around and experiment with the knowledge that "if something goes wrong, I'll just restore the backup".
And with Odin, you only had the choice of Stock Roms. Now you have a few more.
cheers
Yes you can install Any rom for note3
Here is my experience with installing roms on note 3 after unlock bootloader
you should Flash twrp-2.8.7.0-hlte-4.4.img by ODIN for the hlte roms or twrp-2.8.7.0-hltevzw-4.4.img if you looking to flash verizon roms ,
im on Phronesis Rom N7 now and i tryed many roms
AryaMod N7 & S7 Edge
MagMa-NX from NXT TEAM
Resurrection Remix Nougat 7.1.1
CM 13 ROM 6.0.1 for Trader418
Purify CM13 6.0.1 ( the best CM13 till now )
and more ...
i have only one problem that i cant get LTE in mobile network always on H+
i tryed to add screenshot but i couldn't its my firist reply :laugh:
@ALPHA85
Pretty informative first post - thanks, and welcome aboard!
Are you on a Verizon SIM? If not, have you been flashing modems from other Note3 devices?
Just curious; I don't have much experience with radio issues or carrier activation issues. Trying to port a carrier-specific ROM elsewhere (esp starting from a VZW ROM) looks like a massive pile of interlocking software dependencies, though. My respect to anyone who can succeed at it.
Feel free to write a brief summary about what's broken in each - any of them have NFC working? I was on CM13 (trader418) for a long time and would have been happy to stay there were it not for all the GPS issues.
Thank you ,:angel:
i dont use Verizon SIM becouse im from egypt, i bought my verizon note 3 by wrong , when i bought it i saw N9005 under the battery and in the boot screen also inside the rom ,it was lollipop 5.0 ,but sinse i did factory rest i surprised it change to N900V even the imei changed , till now i cant understand how they flashed N9005 rom for N900V device with locked bootloader
i'm on OF1 bootloader unlocked and i flashed PL1 Modem i thought maybe it help me to get LTE but still the same H+
about NFC i really didn't try it at all , i always disable it by titanium pro

When you first got it, did it appear to have a Verizon ROM on it? (For instance, the Verizon splash screen?) Or some other carrier's logo?
Actually, that cleared something up for me. Well, except for the part about the IMEI changing
Apparently there were both LTE and GSM models of the "Note 3" that were sold in international markets. I understand the LTE version was originally sold in China, but the GSM model is more common?
The SM-N9005 is an LTE phone (I don't know about CDMA) with the Qualcomm MSM8974 processor
and the N9000 is the GSM model with an Exynos 5420 processor
So that probably explains the binary compatibility of the SM-N900V and the SM-N9005 - same processor, and both phones were designed for LTE service.
But your report should give @cyberoptics a little less pessimistic view of things; thank you for that.
But I wouldn't go so far as to say you can flash ANY Note 3 ROM. Even though both the Exynos and Qualcomm processors use ARM cores, they are fairly different - the Exynos has 8 cores, half of which are Cortex-A15, and the MSM8974 has only four cores which are Krait- something or other. I think they are not quite compatible. Note that in theory, ARM code that was compiled to earlier standards (e.g. thumb, armv5) would certainly work on both devices - but if they compiled ALL the code in ROM libraries that way they would be giving up a lot of performance on either device. So.... to the extent that they target processor specifics for either Cortex-A15 or Krait, they will be incompatible.
cheers.

bftb0 I just wanted to thank you once again for your consistently helpful, verbose posts about the N900V. I've been using CM13 thinking it was the best thing going, when, as nice as it was at the time, it doesn't hold water compared to AyraMod, which I switched to yesterday after reading this thread.
Now my GPS won't take me sailing past Easter Island when en route to a noon meeting downtown. Maybe Google Cardboard will even work, now that NFC appears to.
Thanks again, and please don't ever bore of being a great and helpful resource, we need you!
