Hi i have recently purchased a Galaxy Tab 4 8.0 and am looking into building a Deodex Rom for the device.
The issue is i have not been able to find anywhere on the forum a custom recovery of any kind for this device. I have tried a few versions for other devices such as the Tab3 8.0 and Tab4 7.0 but each time i could not boot into recovery, brought me back to download mode.
My main question and concern is lack of support for this device and i would like to start contributing.
Is there a CWM or TWRP for the Galaxy Tab 4 8.0 (T330NU)?
If not how can we get one started?
Really want to finish making my custom rom, have all my files Deodexed and ready to go.
UPDATE/EDIT OCT 22:
Source file has been found for this device. If we work together we should be able to FINALLY get a recovery for the Tab 4 8.0 T330nu. If anyone has any useful information or resources to help along the way please feel free to contribute.
SOURCE FOR GALAXY TAB 4 8.0 T330NU (DOWNLOAD USING GOOGLE CHROME ONLY)
http://opensource.samsung.com/reception/receptionSub.do?method=sub&sub=F&searchValue=T330nu
UPDATE/EDIT OCT 23:
Recovery should be in the making for the T330NU variant plus 2 or 3 other variants all in due time so please be patient and let us all work together.
Custom Roms could be on the new horizon to fallow you never know ?
UPDATE/EDIT OCT 26:
Boot.img and recovery.img files dumped from Galaxy Tab 4 8.0.
Boot.img dumped from device T330NU:

I was under the assumption that the source files come from open source.Samsung.com, of which all three Tab4 models are represented

So would this be the correct source for this device as fallows.
http://opensource.samsung.com/reception/receptionSub.do?method=sub&sub=F&searchValue=T330nu
I believe so, can you download that?
I am downloading it as we speak. Only downloads with Google Chrome.
Was my birthday today so been very busy. Hope to get this going
File opened somewhat
More pictures

Seeing as how our tablet has the Snapdragon 400 chipset, same as in some popular Motorola phones and the like, there is pre-existing development that could benefit us, not to mention the relative ease of Qualcomm developing.

I'm just wondering tho it's a bit off topic but only for a brief moment. I have deodexed files I want to replace from the stock Samsung Rom.
My question is do you know any good programs for extracting and recompiling a stock Rom for recovery install after I have modded and replaced files?
Would prefer to compile the Rom on the computer and have the option to make changes and compile a Rom on the phone/tablet itself. As I said I know this is slightly off topic from the recovery but on the other hand after recovery comes the roms and tweaks. I have a file on standby to deodex stock Rom for t330nu.i have been doing research on programs and ways to do it just figured could get a quick tip or flash of insight.

Edit:
Discovered "Tickle My Android" should help for the most part
Just want to check in. Still nothing for us yet. I don't want to push the guys since they are doing this purely as favors since they don't have the devices. I am keeping in touch with them however. Also I pmd @Dees_Troy but haven't heard back there either. One of my buddy's is a friend of his and said he usually won't make a recovery for a device he doesn't have but if a recovery is made and proven working, he will make it official which means more support.

Any updates yet?
Just as the title says. My device has been bricked, unlike any other Samsung devices, I cannot find any links to download a stock firmware for it. It's almost been half a year I'm searching with no luck, even Sammobile I can't find one and any links I've searched on Google are broken. Shame it's just lying around and I can't use it. A working link for free download and any other method to fix my device is appreciated.
Thank you.

Hi and thank you for using XDA Assist
Search on Google (You're best friend), i'm sure you will find it.
Make sure to use these keys in your search: SHV-E230L and stock firmware
Good luck!

I did that a long time ago as I said on my message above and I did again today. Some links are broken including hotfile.com and other results on Google. Others require payment online to be able to download but I think those are scams and I don't know how to do online transactions like credit card payments since I don't have one. I am looking for a link which I can download a stock firmware of SHV-E230L for free like all firmwares on Sammobile or also any methods to fix this bricked device besides flasing it.

For starters check whether the tablet enters into recovery mode. If not - no firmware does not help, you must contact the Service Center (or the trash). A firmware try looking for "KIES_HOME_E230LKLUAMG2_E230LLGTALI1_1220323_REV00_user_low_ship.tar.md5" or "KIES_HOME_E230LKLAMA3_E230LLGTALI1_887051_REV00_user_low_ship.tar.md5"- much in the Chinese resources. In my Yandex.Disk I put the firmware from hire, but I somehow did not understand that for the file extension is "egg" (I renamed to zip, but didn't become clearer more out). And there's a magnet-link torrent, but I feel that the non-operating: https://yadi.sk/d/Qt98o5XHnx9vk At least, I have not downloaded.

All,
Due to the recent accidental leak of Samsung eMMC vendor commands allowing write to protected eMMC areas, we are now able to write CID values on production devices.
Beaups has written an awesome tool called 'SamsungCID' (found here: https://github.com/beaups/SamsungCID). This makes the process all teh simpler!
I have built this tool from his source, and used it on a multitude of devices that use a Samsung eMMC. It works without flaw on the Moto G (Second Generation), Galaxy S5 (VZW/ATT, though, ATT doesn't have a Developer Edition that I am aware of), and many, many others.
How does this apply to you?
The S5 uses a Samsung eMMC, and has a Developer Edition. This means that it is vulnerable to this exploit.
How can I help this progress?
I need a few thing to make this work:
- A few testers with Production devices, and root (temp-root should work fine) -- I will contact these people individually, do not ask here to test.
- One person with a Developer Edition that has root (need an aboot dump, and them to run one command).
If any of you know of someone with a Developer Edition, please get them in contact with me. I can be reached on Hangouts, or on Telegram (@npjohnson).
PLEASE do not post your CID publicly.
I will be trying to package this into an app that will extend across multiple vulnerable devices.

I know we'll be able to get a bootloader unlock from this, but hopefully we'll be able to get it done ASAP. I've already moved on to the Nexus 6, but I'd still love to have my S5's bootloader unlocked anyway. Good luck with this, I can't wait.

cant wait to see this going
So how have you gone about compiling and running this? Try as I may I can't seem to do a proper build. It's probably the lowest of the low, but if you could send me a binary, I'd greatly appreciate it
I'd be more than willing to try it on my rooted verizon s5.
Successfully compiled the tool - currently scouring the internet looking for anyone with a developer edition that might be able to help, we should have this done in no time. Have already sent out messages to a few, will look for more. I'll PM you if I get any details
Kinda cool watching this unfold over a few weeks, I'm really excited for what's to come.
You all need to check something else first, you need your current CID
If it starts with anything other than 15, this will not work for you. Samsung EMMC's start with CID 15, Toshiba 11, and there may be more. If you Don't start with 15, this WILL NOT WORK.
Regarding a compiled verison
http://s000.tinyupload.com/?file_id=64141875024257149501
Yeah...unfortunately mine starts with an 11 :c
Yep, mine starts with a 15. I'm ready to start any testing. All of my possible developer editions have fallen through - many requesting a purchase of the actual phone. I'll keep looking, but I might be outta options atm.
I can't believe all we need to open this phone up is a dev phone for a few minutes. It would add new life. I'm searching out people as well. Hopefully we find something soon
Mine starts with a 15 and it's not my daily driver, count me in for testing!
Question. Didn't someone post in one of the forums (General or Android Development) about them having a Walmart Straight Talk S5 and that it was actually a VZW Dev Ed? Because he was wanting to put a CM ROM on it. If that's true, then we also need to find anyone with that particular device as well. If i can find the thread it was posted in I'll add the link. Found the links. If it's true we need to see if these variants could help out.

That's actually brilliant. It MIGHT work, but even though they have identical hardware, I don't know if that guarantees that it will have a compatible bootloader - unless it does, in which case that's amazing, and we need to get a hold of someone with one asap. Unless they are the same model, just rebranded, I don't see this working as the bootloaders may not be signed with Verizon's keys.
True. Forgot about the VZW keys... Was thinking too much of finding a Dev Ed....lol

Don't give up hope so fast. I'm getting in contact with a few people, and I'll certainly try it. This may actually be the same phone, I see a lot of websites suggesting Straight Talk phones are the exact same as Verizon ones. We shall see. My information about the keys might not even be accurate, with my limited knowledge.
It was a good thought though, even if it isn't true

Hmm. I dunno. I'm currently on Windows - there wasn't really any installation for NDK, just running from the extracted folder. I can post a link to a compiled version of the program, I'm pretty sure someone in another thread posted one.

Use eMMC brickbug checker on the play store. First 2 numbers of your cid should be 11 or 15. You want 15

Hi Guys,
I am new to Android (a noob) - Started with flashing some custom ROMs on my devices and i am bothered by the security of my device, although android is open source, is it possible that a custom ROM is bugged to steal your personal or financial information? I don't have any experience with android development and i don't have time to jump into Android development so even if the ROM is open source i wont be going through the code to check for leaks or potential built-in hacks.
Basically my question is, is it safe to install Unofficial ROMs such as CM unofficial? I understand, the majority of apps store sensitive data on device in encrypted way but still, i don't think it will be hard to just modify the ROM to develop a built-in key-logger OR read username/password from a username/password fields while user is typing using an on-screen keyboard, save it as LOG file and when connected to the internet, send it to the 'unknown' source. I can see so many possibilities, the user wont even have a clue that they are sharing data. it is like Microsoft making windows Open Source and people making their own versions of Windows and users installing them on thier PCs.
Please help me understand - How safe are our devices when running on custom ROMs from developers we don't even know (no disrespect to any dev, all this amazing work is appriciated, I just want to understand the security of android - Please help me understand as after flashing custom ROMs on my devices i am avoiding installation of sensitive apps or even using chrome to type my passwords) - am i paranoid ?
Cheers
It's entirely possible that a malicious custom ROM could steal your data (or worse), and there's really no technical way to mitigate it. You're implicitly trusting the developer of a ROM by flashing it. All you can really do is make sure that whatever ROM you choose is from a well-known, trusted developer.

You are paranoid but that's good!
Yes we are trusting the devs (or Samsung et al with stock) AND hopefully smart coders who regularly check the code (but I suspect checking doesn't happen a lot!). You can use a firewall/packet sniffer to check what servers your phone is connecting to and see (some) of the data being sent to reduce your risk and put your mind at ease. But still it's no guarantee, as I understand it (I'm no expert!).

If you get a stock android you are also trusting the developer. Just look at these lenovo laptops which had malware served on their stock windows versions. Best is to always start clean when buying any form of product.

That's true, but how do you define ”clean”? In theory, you could build AOSP for your device yourself so you're only trusting Google, but that's completely impractical for most people. If you just switch from stock to someone else's custom ROM, you're just changing who you're trusting.

Another question for you: if a ROM has malicious code that send personal information to unknown servers, is using a firewall like AFWall+ twhich blocks all system apps sufficient to prevent this malicious ROM to stole data?

No, a custom ROM could make data look like it's coming from any app it wants, or just bypass the firewall completely.

Alternatively if the device is on your own network you could wireshark it using a computer and monitor IP addresses that the device attempts to connect to.

This is helpful but not perfect. There's a bunch of ways to stealthily exfiltrate data over a monitored network, and don't forget a malicious ROM might only do its dirty work over cell and not Wi-Fi for this very reason.

I agree with you it's not a perfect solution; this question is sort of like asking if you can trust someone who has a root account to your computer when you cannot see what they are doing, it's an incredibly disadvantaged situation from the start.

Remember, everything I've been saying is reasons not to flash a ROM unless you trust the dev. None of it is saying that devs aren't trustworthy. I don't know of a single instance when a well-respected XDA member's ROM turned out to be malicious.

Thank you for clarifying that but the question comes once more: how to recognize a well-respected XDA member? With the number of thanks? It is obvious that if the smartphone you are interested in is not so famous, there will be few comments on custom ROMs, too. So, how to evaluate the reliability of a xda dev who is developing ROM for not-well-known devices?
Are ROMs in Original development Section trustworthy?

Number of thanks can hardly tell that a dev is reliable or not(in some cases it can), rather it's the quality of their work and their expertise on the related topics that could clarify their position a bit. the recognized contributors, recognized developers, recognized themers you should look at cause
these are given to a member after being checked and passed by moderaters here on XDA. So they are pretty much reliable guys. in cases where there are no recognized developers and hardly any comments. you will have to check and find out yourself
1. ask the dev if he has tested the ROM himself?
2. how did he compiled the ROM? is it a port or just a modified copy of another ROM or a build from source.
3. check the link of the download, if it's to some survey site or ask for a password, stay away from it.
4. if you trust the download link, then download scan with antivirus and unzip the file.
5. generally I look inside app if there are apps which I don't trust and I remove them, then check build.prop, init.d folders. basic things to look for is any references of some other website/ports in between codes. if you're more paranoid you can check bin folder as well and every other you want.
6.don't install the ROM simply Root and debloat.

these are given to a member after being checked and passed by moderaters here on XDA. So they are pretty much reliable guys. in cases where there are no recognized developers and hardly any comments. you will have to check and find out yourself
1. ask the dev if he has tested the ROM himself?
2. how did he compiled the ROM? is it a port or just a modified copy of another ROM or a build from source.
3. check the link of the download, if it's to some survey site or ask for a password, stay away from it.
4. if you trust the download link, then download scan with antivirus and unzip the file.
5. generally I look inside app if there are apps which I don't trust and I remove them, then check build.prop, init.d folders. basic things to look for is any references of some other website/ports in between codes. if you're more paranoid you can check bin folder as well and every other you want.
6.don't install the ROM simply Root and debloat.

I've just unzipped ROM but I can't find what you said. I've only found build.prop and nothing else!
Here a screenshot:

That's because lollipop and marshmallow ROM files are further zipped into system.new.dat files which needs another method to extract, https:\\forum.xda-developers.com/android/help/extract-dat-marshmallow-lollipop-easily-t3334117
Just a small correction. When going to aosp you I ly are trusting yourself as you can inspect everything you add and remove what you don't.
Now to add to your paranoia. A custom rom could be made that allows all apps root permission without the users knowing. Add in a Key logger and have e it all headed without you ever knowing. This is common is xiaomi and other china based devices.
Heck there are a few key parts in the playstore with built in Key loggers.
Heck most of the go apps send all their data to China. Things like their Keylogger files, screen recording and device usage. But mind you it is all legal
SM-G389F Marshmallow Port for SM-G388F
Hello Everyone,
So we all know that the SM-G389F has Marshmallow as it's OS,
But when we look on the side of the SM-G388F, we still have Lollipop as it's OS, So I decided to port the OS version of the SM-G389F to the SM-G388F while configuring it to be compatible with it's hardware! :laugh:
I might need some help....
But we can start by Converting the Firmware Download to a Zip for the Custom Recovery to flash it
(Link to Download)
Thanks for Tuning in,
I will keep you all Updated soon! :fingers-crossed:
Hello Everyone,
I've wasted plenty of time trying to extract the SM-G389F Marshmallow Firmware but it was all for nothing. So now I am asking you all who own this device to flash the ROM link above using odin (https://www.sammobile.com/firmwares/galaxy-xcover3/SM-G389F/BTU/download/G389FXXS1APK1/114774/) and then creating a backup via TWRP including the system.img and the boot.img and sending it to me via Dropbox, Google Drive...
Anyway I would like to forgive myself for failing to do this operation without owning the phone because of the md5 protection, but now I will be leaving this part in your hands
Thanks in Advice,
Diamond26
For all intents and purposes consider the two devices as completely separate/different. First of all the got completely different SoC's (not revisions but completely different brands of SoC's). I started try to compile LineageOS (my sources are up on github), but I was facing completely obscure or unheard of errors that where difficult to fix and the amount of free time I have has changed so I more or less have stopped doing that for the time being.
I will be writing up all the info I know off the device but that task has gotten away from me at the moment due to computer problems.

Oh ok!
I was just eager to see if someone with a SM-G389F has come, maybe he could back up his 6.0 Stock ROM and maybe I could modify it.
That's why!

Please re-read my initial post in this thread, it's not possible. Your dealing with two different types of SoC's, so what your proposing is not possible, compiling from stock Android sources is (if you can fix every compile error)

I just want to mess around with the ROM, maybe I could modify something!

Do what ever you want, you can still mess around a lot, you just can't transplant files from the value edition to the Normal edition.
There is some cool mods you can do if you modify system apks.
