[Q] Flash Custom ROM with Odin?

Hi,
How could i flash Custom ROM with Odin..
Because
1. I am not able to go into recovery mode by holding Volume up+Volume Down+Power Buttons
2. I could not reboot into recovery mode using adb commands (stuck at at&t screen)
3. I could not reboot into recovery by flashing any kernel with CWM.. obviously i have to use volume up+Volume Down+Power Buttons again :-(
I am able to flash stock ROM through ODIN 1 click downloader (currently on I897UCKI2)..and its the only way i could flash a ROM now..
So is there a way to install custom rom through ODIN ?
Please help...

If you can get into download mode (power off, hold V+/V-, insert USB), you can try flashing a ROM via Heimdall. Apex 12.5 has a package you can flash from Heimdall.
You can also try Mosaic 9, as that has an Odin-based installer package.

Hey,
I'm using samsung galaxy star s5282. I rooted this phone 2 days ago. Everything went good until today when i was i my class it suddenly switched off. When i rebooted it, it hang on the samsung logo.
I tried to boot into cwm recovery mode by pressing v+, home, power but it boots into default system recovery mode.
I again flashed cwm recovery many times using odin but it dosent work. Odin shows pass but when i reboot my phone in cwm recovery mode my phone enters in default system recovery mode.
What should i do please please please help.....

Note many devices will replace your custom recovery automatically during first boot. To prevent this, use Google to find the proper key combo to enter recovery. After typing fastboot reboot, hold the key combo and boot to TWRP. Once TWRP is booted, TWRP will patch the stock ROM to prevent the stock ROM from replacing TWRP. If you don't follow this step, you will have to repeat the install.
applies to all recoveries

Surenda 1863,
I had exactly the same problem and it took me almost one week of fiiddling and searching the Web to solve it.
The solution was in front me since day ONE : install ODIN on the PC !
In my case, I had I had accidentally wiped out the stock ROM and the tablet was hopelessly frozen on the download mode. I couldn't turn it off to boot it back with any of the usual buttons ( Volume , Home, Power)
I made the wrong assumption that since my PC didn't see the tablet, it couldn't connect to Odin either . I was wrong!
Here is what you have to do:
1. Install Odin on your PC. Connect the tablet to it. You will see that Odin sees the tablet because there will be a caption saying "added" on the top left.
2. Press the AP tab button at the right to go to the location where your Stock ROM is. The stock ROM file will have an MD5 ending.
3 Once the file is loaded (next to the AP button) just press Start. You will see the DOWNLOAD bar gradually filling up on the tablet and at the top left of ODIN.
4. When the operation is terminated, you will see a caption " PASSED" at the top left of he Odin screen and the tablet will automatically boot up to the HOME screen.
As simple as this! I didn't even have to worry about flashing the TWRP ( or CWR) recovery system, probably because the OS ROM was already wiped out. May be your case is different. I only know that in my case it worked like a charm.

Hello abdurm, could you tell us your current firmware? You would require to give us details from Settings > About phone.
Also, did you try flashing anything? If so, what was it?
By pressing the Volume Down button + Home button + Power button simultaneously, does your device enter Download mode?

It dosen give me enough time to check firmware version, it reboots. It is on ICS. It is stock and I have not tried fashing or anything.
Yes it goes in download mode by pressing Volume Down button + Home button + Power button simultaneously.

Flash gingerbread rom in PC ODIN only and it will automatically reboot by itself but if still stuck in samsung logo go to recovery mode and wipe data and cache.

Thank you very much. Just one last thing I dont have to be rooted to instal this ROM and it is ok to flash directly from ICS . Just downloadFilename: SGN_XX_OXA_KJ1_FACTORYFS.zip and flash it. And it will leave me with GB?

Apologies abdurm, I foolishly presumed you would have made a note of your device's firmware details at some point in the past. It was stupid of me to ask you for the said information.

1] Download the pre-rooted stock Gingerbread firmware, SGN_XX_OXA_KJ1_FACTORYFS.zip and extract it to get the SGN_XX_OXA_KJ1_FACTORYFS.tar file.
2] After doing so, run PC ODIN, select the PDA tab in it and point to the extracted file (SGN_XX_OXA_KJ1_FACTORYFS.tar). Auto Reboot and F.Reset Time will be selected by default. Do not select anything else.
3] Put your device in Download Mode and then connect it to your PC via the USB cable. The ID:COM label in PC ODIN will turn yellow indicating your device is connected and recognised.
4] Click on the Start button in PC ODIN and wait for the label above ID:COM to say Pass. After it does so, disconnect your device from your PC.
Your device will reboot and you will be on a stock Gingerbread firmware with root privilege.

Hello again abdurm, I am glad to learn your device is up and running again. :highfive:
Now that you are on a rooted firmware, I would advice you not to avail an OTA update as there is a very high likelihood of it breaking/undoing the root privilege.
Personally, I have not ventured into Ice Cream Sandwich yet and thus I have no right to guide you with the process of acquiring it. But, based on your quoted post may I ask you if you desire to have stock Ice Cream Sandwich with or without root privilege?
I recommend you thoroughly read dr.ketan's threads which explain the subject at hand.

Problems installing TWRP in Tab S2 T713

My Tab S2 T713 is currently running the latest stock Samsung rom. I want to install Lineage 15.1
I've downloaded twrp-3.2.1-0-gts28vewifi.img.tar & Odin 3.12.7. I can boot into download mode, flash TWRP with Odin which says success & my tablet reboots normally. When I power down & reboot into recovery TWRP gets over written by the stock recovery.
If I uncheck Auto Reboot in Odin, after flashing success, I'm still in download mode - I've read that I need to boot directly into recovery from download mode - how do I do this?
In download mode pressing home + voldown + power reboots normally. Pressing home + volup + power does nothing
What am I doing wrong?

Instructions:
Flash with ODIN 3.10.7 in the AP slot.
Put your device in DOWNLOAD mode.
Uncheck Auto reboot.
Load the respective file below into the AP slot and hit start.
After flashing and ODIN reports PASS immediately reboot to recovery by holding POWER + HOME + VOL DOWN.
As soon as the screen goes blank change to VOL UP whilst still holding POWER + HOME.
You should now see TWRP recovery.

Brilliant - thank you. Why they can't have they have that in the Lineage install instructions?
Now running Lineage 15.1 = happy bunny

Good to hear! Please make sure you give a thumbs up to anyone who helped. It really keeps the community alive and kicking!

I found that I had to do this from completely powered off state:
press home + volume up + power
wait until second "sentence" appears on screen in yellow (the first "sentence" is blue),
Then release all buttons
twrp now boots.

for some reason, my internal and external storage is showing 0 mb. Anyway to fix this?

Try formatting (not just wipe) data.

Should the Galaxy Tab S2 2016 be on TWRP 3.2.1.0 or the new 3.2.3.0 for Linage OS 15?
If so, can't you just flash the update using TWRP on the img file, or is ODIN on the tar needed?

OK, I updated to TWRP 3.2.3 using TWRP Recovery and the img file. Appears to work fine.

Sorry to revisit this issue. I can't get TWRP going on my S2 Tablet. I understand these instructions, but at the end of the ODIN installation there are two possibilities that I can see. If you set the ODIN to automatically reboot then you cannot do the above because it says to do it from completely powered off.
If you don't set ODIN to reboot automatically I can't get the tablet to turn off. I can only get it to boot by holding home+volume down + power. How do I get the tablet to power off before booting??
I am using ODIN 3.14.4 and TWRP-3.7.0 9-0-gts28wifi.img.tar and my stock firmware is NRD90M.T713XXS2BSG1 with Kernel 3.10.84-14953299
Thank you.

Found a way to root with magisk and Odin.

Hi guys while searching the web and the forum to find a way to root our phone I found this guide https://topjohnwu.github.io/Magisk/samsung
you can do it by yourself if you want but I thought to edit it a bit to match our device. all credit goes to original developer I just copied what he did and it worked.
I don't take any responsibility if anything happens to device, brick ect. use the guide with your own risk!
make sure you have updated drivers and a good usb cable, I recommend Smart Switch for pc you can download in the samsung site, it will also install latest drivers and you can back up the phone with it to the pc.
just for your information rooting voids the waranty, trips knox and makes things complicated, but I can't have a phone without root, it reminds me the days with my old nexus 4.
this guide will also factory reset your phone so make sure to back up everything don't forget to back up whatsapp in the app itself.
I'm not a developer maybe there is an easier way to root, this is the only way I found, so if you want to wait until an experienced developer who knows english better then me release another way to root that's fine by me, I wont get upset.
the only downside I see in this kind of root that you can't normally enter the system. I mean that normal reboot and power up will boot your system without magisk, because the root sits on the recovery or something like that. so each time you power off your phone to power it up you need to hold the Volume up + Power button untill you see the bootloader unlocked warning and release, and everything will be working with root. even if you accidently powerd your phone without the way I mentioned you still have root don't panic like I did just turn off the phone and power it up like I mentioned and its all good.
also you can't normally update the phone through the phone settings and to update the phone with odin like I understand you'll need to have a patched version of the AP tar file with magisk, or something bad will happen to the phone, again I am not a developer I don't know the full risks.
so after the warnings and the long intro here is the edited guide:
Unlock the bootloader - this will wipe all your data so make sure to back up before you start anything!
Allow bootloader unlocking in Developer options → OEM unlocking
Power off your device. Volume Up + Volume Down + Power button and plug in your device to a PC to boot into download mode
Long press volume up to unlock the bootloader. This will wipe your data and automatically reboot.
the developer also mentions that sometimes it wont work because something called VaultKeeper. I didn't had that issue just make sure after the system boots after you unlocked the bootloader that the OEM unlocking option exists and grayed out in the developer options.
Instruction
1.Download the firmware for your device.
2.Unzip the firmware and copy the AP tar file to your device. It is normally named as AP_[device_model_sw_ver].tar.md5
3.Install Magisk Manager from the Canary Channel
4.In Magisk Manager: Install → Install → Select and Patch a File
5.Select the AP tar file. Magisk Manager will patch the whole firmware file and store the output to [Internal Storage]/Download/magisk_patched.tar
6.Copy the tar file to your PC, and boot your device to download mode. (Hold all 3 buttons Volume Up+Volume Down+Power Button and connect to PC cable)
I have downloaded the firmware with Samfirm I found it on the forum I'll upload it here. I will also upload the AP file I patched and write the firmware version I took it from. I'll also upload the full firmware for you if you can't find a good mirror online. and also the odin version I used.
the csc i look up is for ILO but I think the csc have multiple regions, you know better I'll upload it anyway maybe it will save time for someone.
7.Flash magisk_patched.tar as AP in ODIN (I flashed the entire firmware because I had some problems flashing without all the files try it the way you want. flash it with normal csc of you choose to flash the whol firmware)
Important: Uncheck “Auto Reboot” in Options!!!!
8.Magisk is now successfully flashed to your device! But there are still several steps before you can properly use the device.
9.We now want to boot into the stock recovery to factory reset our device.
Full data wipe is mandatory! Do not skip this step.
Press Power Button+Volume Up+Volume Down to exit download mode, and as soon as the screen turns off, immediately press Power Button+Volume Up to boot to recovery partition. Just as mentioned in the previous section, since we want to boot into stock recovery, continue pressing the volume up button until you see the stock recovery screen.
10.In the stock recovery menu, use volume buttons to navigate through menus, and the power button to select the option. Select Wipe data/factory reset to wipe the data of the device.
11.This time, we can finally boot to the system with Magisk. Select Reboot system now, and immediately press Power Button+ Volume Up. After seeing the bootloader warning screen, release all buttons so it can boot to the system.
12.The device will automatically reboot for the first time it boots. This is completely normal and done by design.
13.After the device is booted up, do the usual initial setup. The following steps will need internet connection.
14.You shall see Magisk Manager in your app drawer; if not, manually install the APK you downloaded in step 3 and continue to the next step. The app would be a stub and it shall automatically upgrade to the full Magisk Manager when you open it.
15.Magisk Manager will ask to do additional setups. Let it do its job and the app will automatically reboot your device.
16.Baruh Ashem! enjoy magsik!
That's it I think if I forgot something I'm sorry I hope it worked for you! and maybe some real developers start to look at the device and start building costume roms andall the good stuff that comes with it!
meanwhile the files are uploading you can try get them by yourself here are the names of the files I used:
Odin3_v3.13.1_3B_PatcheD
Samfirm
firmware file: SM-A705FN_1_20190412140953_u5ql0uali6_fac
Magisk manager is linked the developer enterd the canary build but I'll also upload 7.1.2.apk version I found on the internet.
ALL CREDIT GOES TO THE ORIGINAL DEVELOPER, AND DEVELOPERS. if you have any question I can help you with my own expirence only.
Here is the download link, use at your own risk. if you are not sure the firmware uploaded is right for your device download yourself with samfirm that i also uploaded.
Download Link - Google Drive

Thanks for your research and this manual! I've been trying your steps for a few hours now, and after a few trial and errors, softbricks and reboots I'm still not able to succeed.
Magisk Manager won't show up in the apps after setup wizard. Installing it manually, it says Magisk is not installed
My phone: A70 from the Netherlands. I used Israel firmware from updato.com (https://updato.com/firmware-archive-select-model?record=440E12D670B911E9BE8CFA163EE8F90B) and your file (which is same size after patching). Unfortunately I can't find Dutch firmware, hence the Israel version.
Anybody else succeeded?

I have good hope that this device can be rooted considering my past Samsung devices, it is only a matter or time.
I'm downloading the files again now, and going to try! Will report back a.s.a.p.
Edit:
Installed everyhing from your files in Odin: BL, AP (patched), CP, CSC and:
It worked! Magisk installed, Magisk Manager updated. I could install AdAway and it asked for root permissions.
But... after reboot Magisk Manager said it is NOT installed anymore. Now what?
Edit 2:
It seems Magisk sometimes fails to load when booting. After some reboots, it is back again and AdAway works. So end of the story: IT WORKS, and it Magisk starts to nag that is it not installed, just reboot a couple of times, and enjoy your rooted phone

Magisk isn't loading because of you want to boot with magisk you need to hold the volume up and power button together untill you see the bootloader unlocked warning and it asks your to press the power button to continue then release press the power button. I usually press volume up and power button again for 2 sec to make sure and that's it! Reboot won't boot with magisk sure make sure u use this method each time you need to reboot!

It's not that bad, even if you accidentally booted without magisk just turn off the phone and boot with the way I mentioned and magisk is back!
If you normally power up your phone just pressing the power button with this method just add the volume up and hold both button together for 4 to 5 sec.
Right now it's the only way to root that I found. Maybe with twrp things will get easier.
And one more thing if you install magisk module don't press reboot after your install just power off and boot the way I mentioned that's it.

I tested a few reboots, and this is how my A70 behaves:
X Reboot without pressing any buttons: no Magisk
X Reboot, pressing the power button when prompted: no Magisk
V Reboot, hold power button + volume up button, press power button to confirm: Magisk :victory:
Well, that's good enough for me! I am happy :laugh:

Yeah that's right my English is not perfect maybe I didn't explained it good enough but that's what I meant! Thank you for trying. That's good enough for me also.
I also installed EdExposed and it's working good with modules that are confirmed to work with Android pie.
Next thing is trying to flash mods with flashify or something because we don't have twrp yet.

There is more good news!
I got EdXposed working following this manual, using the SandHook version: https://magiskroot.net/download-xposed-for-android-pie
It was really easy, just download and flash/install these files:
Links:
Riru core: https://github.com/RikkaApps/Riru/releases
EdXposed Sandhook: https://github.com/ElderDrivers/EdXposed/releases/tag/v0.4.1.2
EdXposed Installer: https://github.com/solohsu/XposedInstaller/releases/tag/Ed_v2.2.4
Don't forget to reboot with the button combination trick mentioned earlier!

If it failed maybe magisk didn't patched AP correctly try to extract the AP file again from the firmware file and then patch it in magisk again.

I extract with 7zip and got all ok in magisk. Newest 214 build.
But got success 0 fail 1 as result
Can't be ok like this?

@Avicohen21 I almost bricked it. Send me on pm your telegram contact or something to send you some pictures

[Q] Stuck in bootloop after trying to install a custom ROM, unable to detect the device through ADB/Fastboot [Solved]

Title says it all. But for those that want to know a bit more in detail about what's going on, I tried to install this custom ROM: https://forum.xda-developers.com/t/rom-oneui-2-5-twrp-ncx-2-5-for-a71-sm-a715f.4174135/ Clearly I did something wrong (a bit more clarification in that guide would help people not used to rooting an Android device getting through that process easier), so now I want to go to square 1 by installing the stock ROM again. But the thing is, after installing multidisabler through TWRP, the phone is not permanently stuck into a bootloop and now I can't even go into safemode, nor download mode, and I can't enter the recovery mode, the only thing my phone is capable of doing is to restart by itself by holding the volume down and the power buttons at the same time, and now ADB nor Fastboot can't detect my device (the PC does a Samsung device being connected though, so it's not a hardbrick, I guess).

Samsung devices do not use Fastboot. You should restore through Odin instead.
Try the following:
1. Download Odin on your computer, you can get it from here. Extract it into a folder.
2. Download the firmware for your device. Find out your device model first and then look on http://samfw.com, I've downloaded from there a lot in the past, it works great.
3. Extract the firmware, you should get five files: AP, BL, CP, CSC, and HOME_CSC.
4. Make sure your device is powered off, and press power + volume down + bixby. You should be asked to confirm you want to enter download mode, press the volume up button.
5. Plug your device into the computer, then select the files for all the slots. Use CSC, not HOME_CSC for CSC (CSC is for fresh restore, HOME_CSC is for software update).
6. A device should show in the top bar, something like [COM:6]. This means your device is connected. If it isn't there, make sure your device is plugged in and in Download Mode.
7. Click flash. The firmware should start to flash and there should be a progress bar in Download Mode. Once it's finished your device should reboot into the system.

Well, trying to reflash everything through Odin has been a thing I tried to do, but how am I supposed to shutdown a phone that is stuck at the Samsung logo (is there any combination to shutdown a Samsung during the boot process?)? And even after that, how am I supposed to press "power + volume down + bixby" if both the power and bixby buttons are the same buttons?

I tried entering Download Mode hours ago, but to no avail. Even before flashing mutidisabler through TWRP (and thus, the phone was working), I had to use ADB in order to make my phone be able to enter Recovery Mode, since the combo for recovery and download mode just made my phone make a loud noise and restart my phone onto safe mode.

Ok, here's an update, apparently pressing those buttons, makes the screen have the same, but at least Odin recognizes the drive, but now I'm stuck at this error: "Complete(Write) operation failed."
Something's weird here, I'm 99.9% sure I did activate USB debugging for this phone, although that was just before wiping the entire drive before the phone got stuck in this loop.

Fixed. Many thanks to @hainguyenthao for helping me out ^^

I'm sorry to hear that you had trouble installing the ROM and I'm glad you were able to fix it.
I unfortunately can't see a way that I could make the tutorial on how to install the ROM any easier. I'm almost certain I covered all my bases going over the perquisites and how to install the ROM. I also have a Telegram group in that thread so that users can join if they are ever stuck in any of the steps so that either me or other users that have successfully installed the ROM can help people in doubt since I'm not available 100% of the time. If you ever decide to give it a try again, don't be shy, you can always join the group and request for help.
