Can’t boot - Samsung Galaxy Tab A series Questions & Answers

I had stock rom sm-t510 not sure if the exact build but I decided to try the AOSP 10.0 rom along with the same devs leniage rom, both times I’ve tried flashing in ODIN and TWRP, also flashed another custom “stock” rom, tried a different kernel as well and nothing, all times I get stuck on the boot logo (doesn’t boot loop, just sticks at logo). Also unlocked boot loader prior to flashing anything. I have lots of experience flashing with different phones back in the day and I’ve followed all the instructions like doing a factory wipe to remove encryption after flashing.
I guess my question is what would cause it to get stuck at the boot screen.

Makes sense , I’m not even sure of the build I was on prior to flashing, shame on me! So anyone know how I fix this?

Will try
So if this is the case then I should be able to install stock firmware that the rom is built on (found here https://samfrew.com/model/SM-T510/) and once that is installed then installing rom should work, in theory right? Am I missing anything?

yes, check first post:

There's a real possibility that you may be dealing with the RMM lock, something I've become all too familiar with on my last three Samsung devices...
You can learn about it and how to get around it here:

[Q] TWRP=Bootloader unlocked?

Does having a custom recovery mean your bootloader is unlocked? I have TRWP installed, in download mode it says samsung offical yada yada.
The boot loader is not unlocked. Do some more reading about your phone before you start doing something with your custom recovery. Many people have bricked their phones because they did not understand what they were doing. There is a lot of good advice here. Look for threads by axman, adamoutler,beerdriod, to name a few. They'll keep you out of trouble. Just some friendly advice

I know that the boot loader is not unlocked but rather is a patch. What I'm asking is is having a custom recovery make it safe to flash a rom.

The post above has a great link for you to research.
Basically, having a custom recovery means that you can flash roms that have had the loki patch applied to them or you can flash roms from similar hardware then flash a kernel that has been loki patched, or you can flash a rom from similar hardware using a recovery that has auto loki, or you can flash a rom from similar hardware and follow that by flashing loki-doki.zip.
Plenty of options, but if you have to ask, you shouldn't be flashing, Read the link above and everything else you can about loki and the att i337. Making a mistake with a brand new cellphone can be costly so research is imperative.
Not trying to discourage you from trying a custom rom, just trying to let you know that there's a lot of information you should have first.

Once you get the hang of it, it's not that difficult. It's just slightly different than flashing with an unlocked boot loader. The main difference it that whatever you flash has to have a kernel with the loki patch applied before rebooting out of recovery. The patch can be applied to the roms kernel before you flash, it can be applied to the roms kernel by the recovery you use to flash, it can be applied by flashing a loki patched kernel after flashing the rom, or it can be applied by flashing loki-doki after flashing the rom.
The roms come from identical snapdragon 600 equipped S4's, not the octa-core models and you apply the loki patch as needed with one of the methods above.
essentially it's an extra step in the process with several different places you can put it.
If you've flashed other roms, it won't take too much reading before you get the hang of it, but it's still best to put a little time into research before pulling the trigger.

So the best option would be the recovery that applies the patch automatically correct?

It is easier than the HD2, I had that phone, and it was a nightmare to flash, it is not confusing, I give a STEP BY STEP in my guide, how easy is it...
5 step flash process...I don't get it, HOW HARD CAN IT BE?
here is an example...
1 - get a bowl
2 - open the box of cereal
3 - pour cereal in bowl
4 - add milk to cereal
5 - eat cereal and enjoy
it is NO DIFFERENT than that. If you can do that, you can flash roms.
go here, if you can't do this, then you need to keep your phone stock forever.

I've tried this, but all I get is cereal. I've repeated it exactly as written like 15 times and I think I going to be sick.
I am confused to why everyone has this problem, it is crazy. I am like you, it is embedded into my brain, my wife had to wake me up one time, because she said I kept saying flash it, flash it, over and over. Oh well.
I have seen some people, they don't like going through all the posts to find an answer, back in my early days they included a new feature called BOOKMARKS...I ask myself, what does that do...hmm it takes me to places that I have been before, that dare I say...dare dare.. explain what to do so I could reference back.

[Q] Why...?? CONFUSING!!!!!

I honestly don't know where to start, I bought the Samsung galaxy s4 i337m from virgin mobile, and use it with my Bell carrier. I was browsing the internet when I come to a video that states that you can flash i9505 roms on my i337/i337m phone! So silly of me to try that, it actually worked. When I was tired of that ROM, I go on this forum thread and look for another ROM, a ROM that is i337m cooked, and it soft bricked my phone, 3 times for 3 different i337m ROMS, at this point I have absolutely no clue what is going on with my phone, is the bootloader unlocked? WTF IS LOKI?? WHY does a i9505 ROM work on my phone, and a i337m cooked ROM does not, I just need some answers!! I have been flashing my phone with ROMs since my s1 and now the s4 comes along and completely wipes any knowledge I had before I got the phone, if anyone can help me on which ROMS I can and/or can't flash, that would be great, sorry for english not my first language!
Read and do some research. Just because you flashed a number of other phones doesn't mean you know how to flash this one. Every phone is different. It would also help to know what roms you flashed that didn't work.

What roms did you try to flash? Where did you get them? The boot loader is not locked and they should flash. Did you check the md5sum? They could be bad downloads.

Loki is needed for phones purchased through at&t. The Canadian version is the same phone, but without a locked boot loader, so the Loki hack is not needed.
What I have found is that some of the custom recoveries don't wipe out the phone properly. Try using Odin and go back to stock, wipe, then restart fresh
Also make sure you do a full wipe after flashing a Rom

Actually, I totally found that the Loki fix was needed for my Canadian i337m device (Bell). Many ROMs wouldn't work without it; they'd just get stuck in the boot logo (including SlimRom and CyanogenMod).
Just flash the ROM, then flash the Loki-Fix and you should be good to go.
If you're seriously stuck and you can't get back into your custom recovery, let me know and I'll help you out.
Now I am confused. Why would the I337m need a loki anything?
It is not needed. I surprised it even flashed.

I didn't check the first time, but ever since I had to reflash to stock I started using this firmware: I337MVLUAMDJ_I337MOYAAMDJ_I337MVLUAMDJ_HOME and this kernel:

If I flash a ROM but not the Loki Fix, one of the following scenarios happens: 1. the ROM gets stuck in a boot-loop (continually restarts), or 2. gets to the boot logo and stays there forever (10+ minutes). But if I reboot into recovery, wipe everything again, reflash the ROM and then the Loki Fix, the phone boots up in less than a minute. Is this very weird? The phone is i337m from Bell, Canada.

Strange. If it's relevant, I did encounter a lot of trouble sim-unlocking this phone for use on other networks. Using the Debug Menu on the phone's keypad didn't work as a method for me, although it had been reported to work for many others, including those with i337m's. I had to use a USB tether hack (FastGSM) to finally unlock the darn thing. Perhaps some models have locked bootloaders and others don't.

Using Open Recovery, and put it on the phone via an ADB interface (over USB debugging) using the Canadian i337m "3way" .BAT tool (root/CWM/OpenRecov).

Phone identified as i337m from settings menu prior to any flashing. Model number under battery matches: Model: SGH-I337M / IC: 649E-I337M.
Using Loki came in where I found that flashing ROMs wasn't working. I had already rooted and tried to unlock the phone through the debug menu. Unlocking didn't work, but rooting did and I could load custom recoveries without problem. I thought that I should try flashing other ROMs to see if I could unlock the device through their debug menus, but no luck. The first ROM I tried to flash was a SlimRom nightly. That one appeared to flash properly (recovery said "success"), but upon reboot I got stuck in a boot loop. I then went back to recovery and messed around trying to flash other ROMs and ran into the same issue persistently. I eventually panicked and Odined back to stock ROM and kernel (numbers previously mentioned). Everything was fine after I figured out how to make Odin work. (I even learned how to make signed-MD5 tarballs with Cygwin to try to make flashing recoveries and roots simpler by using Odin.) After wondering why I couldn't flash any custom ROMs, I dug around a bit and found out that some ROMs' first-posts mentioned that certain fixes had to be applied—some of which were labelled ROM-specific (e.g. GOLDENEYE-i337m-FiX-XXUBMF8) and others that just said that they required a Loki fix, and sometimes provided a link to download it. At the time I didn't know what Loki was, and I wasn't understanding why certain ROMs would come pre-"Lokified" (brain was full after hacking around for >6h). So in the moment it made no sense not to try flashing that to see if it would help. Lo and behold, it worked! I started flashing Loki after every ROM install from then on out. Previously not-working ROMs that I had already tried suddenly worked just fine (I didn't redownload them; I kept the same zip files and just started flashing the Loki Fix after each of them to make them work).
It's still the case that when I want to flash a new ROM, I wipe everything from recovery and flash the ROM. If it doesn't boot, I flash the Loki Fix and then it does boot properly.

Huge problem need help

I flashed the Lollipop firmware on my note 4 (910G) and badly wanted to root. In the process of rooting i may have used the wrong CWM file. But i checked it doesnt seems so but i assume. Im not sure. Im not a noob (but not an expert) as i tinkered many phones so many times. But today things went wrong for the 1st time.
The issue is the calibration of the digitizer on my Note 4, its completely off, in some areas it doesnt work at all when using my fingers, but with the S-Pen it seems fine. Its impossible to use the phone, the gap is huge.
I re-installed the stock firmware it doesnt seems to install the stock recovery (Assuming its the recovery i flashed which caused this) hence didnt rectify.
I flashed the philz and twrp recoveries (Correct files) thinking having a working recovery would solve and that too did not help.
I flashed CM based ROM assuming it would make a difference, still no.
Please guys help fix this, and i really really hope its not hardware or triggered any chips to malfunction due to incorrect file flash. Pls help and advice what needs to be done to reverse this.
Thank you...
Flashing official stock firmware should revert your recovery back to standard. It did for me when I was using Cwm and reflashed 5.0.1 firmware.
try your device in safe mode to see if that changes anything. If not I'd recommend doing a complete wipe then reflashing the stock firmware.

No mate tried all that, makes no difference. Even in safe mode its still behaves the same. And installed stock firmware many times, also without battery too. No improvement. Even the stock recovery isn't installed, thats the biggest question i have in that process.

This problem has nothing to do with rooting or installing a custom recovery. Only when upgrading or downgrading firmwares the touchscreen firmware can sometimes bypass the update.

tried to do a bit of light research and couldn't find what's different between this and other preexisting multiboot solutions. I've been using Dual Boot Patcher for sometime without issues. Is this somehow better? and if so, how?

EFIDroid is what you would call a "second-stage bootloader". The main advantage over Dual Boot Patcher (at least for me) is that you no longer have to patch zip files before installing. Also, EFIDroid is more than just a multi-boot solution. Quoting @m11kkaa:
efidroid tries to focus on simplicity, and doesn't require any kernel modifications etc.
in general: well having such a powerful bootloader in your boot stage gives you lots of possibilities, like multiboot, replacements/additions for kernels/ramdisk/cmdline.
This project has a lot more potential than what's currently implemented. i.e. you can give samsung devices fastboot and sony devices a standalone recovery. Also you can natively boot GNU GRUB if you're into booting linux kernel's the desktop way.

The two solutions are similar enough that you can migrate your setup from Dual Boot Patcher to EFIDroid without losing any data. I'll try to post a guide later this week.
I was I under the impression dual boot required multiple ROMs running the same kernel... If that is the case a huge advantage efi has is each ROM having their own boot img. I'm currently running 3 ROMs a lollipop a marshmallow and of course a nougat. I really just wanted to see all 3 latest android os running flawlessly on 1 device. And I did just that hats off to the developer for this.

There's an uninstall button in the app. Or, you could just flash the original boot.img via TWRP (basically what the uninstall button does).

Thanks for bringing us this tool. One thing I can't figure out...how do we Odin a different bootloader? I have DOK2 loaded now, and want to put Dr. Ketan's on the phone. The sub instructions say to Odin the BL and CP, as the ROM is generally generic. There us also a datafix and an essential fix that needs to be applied. Doing all of that is easy, but how do I keep two separate bootloaders (LP and MM) totally separate? If I flash a LP over a MM, my camera breaks, and if I flash a MM over LP, WiFi breaks. And I'm not talking about dirty flashes, a full system, data, and cache wipe 3x. Only Odin back to the base ROM keeps my phone happy.

Thanks for bringing us this tool. One thing I can't figure out...how do we Odin a different bootloader? I have DOK2 loaded now, and want to put Dr. Ketan's on the phone. The sub instructions say to Odin the BL and CP, as the ROM is generally generic. There us also a datafix and an essential fix that needs to be applied. Doing all of that is easy, but how do I keep two separate bootloaders (LP and MM) totally separate? If I flash a LP over a MM, my camera breaks, and if I flash a MM over LP, WiFi breaks. And I'm not talking about dirty flashes, a full system, data, and cache wipe 3x. Only Odin back to the base ROM keeps my phone happy.

There's no way to have two different bootloaders. EFIDroid comes between the bootloader and the boot.img, so it has no control over the bootloader.
EDIT: EFIDroid may be able to emulate the behavior of another bootloader... you would have to ask @m11kkaa for details...

Here is the LINK. You can see more info HERE
I downloaded and started up the EFIdroid unofficial apk but got the following message:
=====================================
Error
Can't load device info. Please check your connection.
/data/user/0/org.efidroid.efidroidmanager.debug/files/devices.json (No such file or directory)
override ota server try again
===============================================
Could you please explain what's going on? Seems that this version is different from the one i downloaded in March. Could it be that it's not getting root access? What can I do to get around this error?

I will have to look into it... The EFIDroid app error messages are not exactly the most helpful kind. (Good thing the app is being phased out soon). That particular error message could mean many things, but most likely it's a connection issue. We will continue this in Slack.
Will this work on tw 7.0 if i was porting a rom. Also why wont aosp kernel work on tw.. i always thought tw was aosp with skin..
Go to back to the link posted above where you got the unofficial apk and go to post #83. The OP posted an apk there that works fine on our phone.

Tried what you suggested but it didn't work either. So, I chose the 'nuclear option': I wiped the phone completely then reinstalled the stock Marshmallow ROM. using Odin. After that i installed TWRP v3.0.2 (trltetmo) and Supersu v2.79 as well as Busybox v1.26. Only then was I able to install EFIDroid successfully. Now, I'm able to boot the stock rom as well as Resurrection Remix.
It seems that if your going to install EFIDroid you must have the phone rooted using SuperSU. Using Magisk to root your phone instead of SuperSu won't work (at least it didn't work in my case).

This should work anywhere, regardless of ROM... But btw, it's a stretch to say TW is just a skin on top of AOSP. In fact, TW is probably the farthest you can get from AOSP... There's a lot of significant differences that make AOSP kernels incompatible with TW ROMs...

[SM-J327P ROM BASE] QI2 Firmware Deknoxed and Deodexed

Like I have mentioned to the others in the J3 Emerge community, I had this done just didn't have the opportunity to upload it until today. This is a Deknoxed and Deodexed base for custom ROMs for users who are currently on the QI2 stock firmware. And since I did nothing but remove the odexes(including the one on the boot img iirc which is why it comes up with the typical custom kernel message on bootup) and removed Knox, I'm not posting this as a DevDB thread as Samsung did all the heavy lifting so to speak.

And yes, this can be flashed as is but as always, you do so at your own risk. I will not replace your device and neither will Boost Mobile nor Samsung in the event of data loss, corruption, theft, fire, pod people, etc.
Please do not mirror this zip without express permission from me.
I believe this COULD be used on VMUS and SPRINT as well, but because I do not have the Emerge from those carriers. Also, from what I see it can only be rooted using SuperSU in Systemless mode or Magisk.
How can i get wifi working after flashing this?

If you're not on QI2 when you flash this, it won't work. No idea how to fix it unless you use the QI2 ODIN package to "upgrade" which is found on AFH under the user the_yankee, iirc. Not at pc so can't verify this. Have stuff to do rn so can't get on one.

Thanks! that's exactly what i was missing, I guess i was using a different version before, flashing the QI2 first did the trick.
I think I will put together a set of zips that can be used to get any of the three we are all on,working on the various versions. All a user will need to do is pick their carrier and flash it in TWRP after first boot that way the system writes the csc directory. I will post you all a link when I get them built. They are sorely needed and long over due.
