which core prime model do I have? - General Questions and Answers

I am trying to put TWRP on an old Galaxy Core Prime (Kit kat 4.4.4), but I noticed that there are 3 different versions, each with its own recovery image. Ive done a bit of research, and the CPU is a Qualcom Snapdragon 410, which narrows it down to 2:
Qualcom
Qualcom CDMA
How can I tell if it is the CDMA version? Model is SM-S820L. I imagine that the L is for LTE, but both versions are LTE so that isn't much help. Thanks in advance for your time & for any help you can offer.

I believe I solved my problem. I found a site that said to check the status section in the settings. Apparently, if your phone has an MEID # it is CDMA. Mine does, so I am going with CDMA recovery version... Hope this helps someone in the future.

[Completed] [SOLVED] [Q] How to root samsung galaxy S5 Model:SM -G900 (k3gduosctc)

I really need help.Few days ago I traveled china and bought galaxy S5.
Now, I want to root the device but In my device the model is only :SM -G900. nothing is written after G900. for that i cant find the version from internet for rooting the device. At last i installed an apps name CPU-Z. In here the model number is showing SM -G900 (k3gduosctc).
But still i can't find the right version to root the device.
plz help me....
You'd need to look at the Sticker behind the battery for determination of the correct Device Model Number. Sometimes the information you see in Settings > About is not accurate. The apps you'd use may get mislaid.
Having said that Since you bought in China, it is likely to either SM-G900I (for Asia Market) or SM-G900K/L/S (Korea Market). My Money would be on SM-G900I. Given that the device is so new, we do not have sub forum for this specific variant yet. But depending on which carrier you are using or planning to use, here are the links to Relevant forums. Sprint Galaxy S5, Verizon Galaxy S5, T-Mobile Galaxy S5, AT&T Galaxy S5
To your question on Root, here's a nice thread for Sprint S5. It gives you a general Idea. But understandably the specifics would depends on your Model.
You may also use Android Hardware Info app or any other Device info apps that look at the hardware to determine Model Number.

Just in addition what Perseus71 already wrote:
Chainfire has already created CF-AutoRoot for various S5 variants.
This is IMO the easiest way to root your device. I have done this with my SM-G900F too.
But first do what Perseus71 has suggested ... you should be sure what exact model of the S5 you have.

Hi nissan0808,
I am sorry to inform you that the "UNIVERSAL5410" is commonly used on fake Galaxy devices ( Mostly S4 ). You can make sure by entering your IMEI here: IMEI Analysis. Check under the IMEI Validity Assessment.
Find it by dailing *#06#
This doesn't necessarily mean that you can't root the device, you can try the following tool:

Rooting US Note 10 Snapdragon

Qualcomm Snapdragon chip 855. I have the most recent update of stock firmware and model Sm-(975U AT & T carrier, Samsung device.) Build no. RPIA>200720.012.975USQU5place . I checked the note 10 forums and the guide section and find nothing relevant to rooting this device. Most of the post focus on Exynos and some info says US model has unlockable bootloader.
If I am not posting correctly, I humbly beg your apollgy, all I ask is that you ("please") point me in th right direction.

How can I know if a ROM is compatible with a phone ?

Hello everyone ,
I make this post related to my last one https://forum.xda-developers.com/t/...get-android-phone-data.4371953/#post-86065033
I'm now wondering what are all the requirements a phone need to be compatible with a ROM.
android sdk version ? model ? etc...
Maybe some ROM have more requirements than others ?
Thank you for your help !

ROMs are individually built for each specific model number(and all variants of that model with the exact same hardware), they can only be used on the specific model number that they were built for.
When a device has many different model numbers of the exact same device, all of its variant model numbers can use the same ROMs. For example, from my own personal experience, I had a Tracfone Galaxy S3 that had a model number SCH S968C but it was the exact same as all of the US Galaxy S3 variants so I used ROMs that were built for the Verizon Galaxy S3 with model number SCH I535 even though my model number was SCH S968C. It was the same way with the US Galaxy S4, Galaxy S5, Galaxy S6, etc...
In some cases, devices that have the same CPU architecture can share ROMs but these are specific cases where the hardware between the devices are close enough to use the same software without issues. But, in most cases where devices have "similar" hardware, they can safely flash each others ROMs but there will be little things here and there that don't work or don't work correctly. 99% of all available devices can only use what was specifically made for that specific model number, for 99% of all devices, using ROMs from other devices results in a softbricked or hardbricked device.
In general, it is best to only use ROMs that were built for your specific model number.
