Custom ROM not working anymore - Samsung Galaxy J3 (2016) Questions & Answers

I have a j3 2016 (j320fn to be exact) and i recently decided to download twrp and flash a rom, i flashed a marshmallow port from j210f and it worked , i was so happy, but one day i went into developer options and i accidentaly disabled them, i turned them on again but forgot to turn on OEM onlock, the next day i turned on my device it couldn't boot, it just said frp lock, so installed the stock firmware with Odin, and the device worked again, i installed twrp again to flash the rom, but this time, things were different, i wiped dalvik, cache, system, etc... and flashed it. It booted into the rom, but when it was on the select language part, it restarted and bootlooped, can somebody please help, i adore this rom and i dont want to have the stock one

[Q] Bootloop on L7. Help pls!

Hello,
First, sorry for my bad english and knowledge on flash/root.
I flashed Slimbean on my P700, everything worked fine, expect of the modem. I tried other ones, but didn't work.
So I decided to change the ROM and flashed CM10.2 on my L7 which was working fine until battery was empty. After loading my phone, I wanted to start it, but it stayed in a bootloop on the boot animation. I tried everything, wipe/dalvik wipe, flashing slimbean --> still bootloop
Now I thought, maybe CM11 could work, but still the same problem, I formated everything expect of sd, wipe/dalvik wipe, flashed the ROM, Gapps and kernel, but still the bootloop...
Any ideas?
It may take a while on first boot. But if it don't load you could restore a backup of you have one or flash a kdz or use LG update tool to fix your issue. Other than that make sure you have word everything in recovery and format system, data and cache before flashing a rom. Do not flash kernel before first boot unless it's required.
I can add to that to flash ROM only without gapps just to get OS to boot correctly.
I already solved it.
I whiped everything, formatted everything except of external sd and than first only flashed the ROM and rebooted, all worked, than i installed the Gaps, rebooted, and last i flashed the kernel, now it works fine but i will never ever reboot my phone or let battery get empty ^^ no more
thanks for your help

Cant figure out how to install custom rom, without loosing root acces

Dear XDA
I have been an android user for many years and rooting has been one of the things I always did to my devices. I am an owner of a Note 3, which I have rooted succesfully and used X-NOTE 13 rom for long time. Last week I wanted to try something new and after that everything seems to be impossible. Before I install any roms I always perfom full wipe of, system, data, cache, dalvik cache etc. (I do it inside the recovery). Afterwards I tried to install CRASH ROM V9 and the progress went fine. When the phone rebooted the strange things started to happened I couldn't find the rom's extra menu and couldnt find any of the functions that the rom contained. I just thought that it was problem with the rom itself therefore I tried to went back to X-NOTE, but without any luck. The X-NOTE installed probably but I couldnt boot into it, it was stucked at the "Samsung Note 3" logo. I tried to wipe cache and dalvik but without any luck and every time I rebooted from the recovery the recovery says "it seems your device doesnt have root access" and the recovery tries to gain root access.
Then I couldnt understand anything of what was happening so I went to stock using ODIN. After installing stock rom I used CF-ROOT and everythings went smooth and I could use SuperSU inside the stock rom. Then I installed a recovery and it didn't mentioned anything about root access, so I was ready to install my custom rom...at least I thought so....I installed X-NOTE again (because I knew that this rom worked before without any problems) and after the progress was done I couldnt boot into the rom again, it was stucked. I wiped the cache and dalvik and as soon I clicked reboot in recovery it tells me that I am not rooted.
Then I did the same thing again, went back to stock, installed CF-ROOT and recovery. This time I installed CRASH ROM instead and I could boot into the system, but the rom still misses the "rooted features" etc.
In other words, what have I done wrong? I cant seem to find the problem and I think that I have tried every possible solution?
Informations:
Model: ​SM-N9005
STOCK ROM: Tried both N9005XXUENB4 (German) and N9005XXUENC2 (Nordic firmware)
Custom Rom: Tried both X-NOTE and CRASH ROM
Recoveries used: TWRP, CWM and Philz CWM
Kernels: Tried with stock one and X-NOTE kernel 1.5
I hope you can help me I cant live with stock roms
Thanks in advance

weird.
all the rom you mentioned xnote & crash come with root access inside.
When you said you used all those 3 recoveries, did you try each rom with each recovery ?
and when you flash those rom, did you follow to do a clean full wipe as mentioned on each OP thread ?
clean full wipe is not only wipe cache and dalvik, but also the data (factory reset).

Yes I have and tried several other combinations too. First time I installed X-NOTE I wiped everything and installed X-NOTE without problems.
I cant seem to break the code, I am getting frustrated hour by hour. I have double checked everything, I am on the NC2 bootloader with the NC2 kernel, when trying to install X-NOTE I get stuck at "Samsung Glaxy Note 3" - I cant understand what the problem may be and it is beginning to be personal :/ heheh
But seriously what could I have done wrong?

To be frank... I have no idea. U flash before earlier, means u know how to flash it.
What I could think of, is just the recovery.
I ve been using cwm chenglu all this time (the one reported with less bugs, and most recommended at any rom thread). And jump from rom to rom every 1 week at least with no issue.
I will try tonite use twrp to flash rom. I will let u know if I face any problem.
SOLVED

Finally, finally and finally solved!
Well it seems strange but the problem was the official kernel inside the stock roms that made it almost impossible to run any custom rom.
What I did to solve the problem:
1. Went back to stock rom using a rom with the newest baseband NC2, ex. N9005XXUENC2
1a. I did have som problems getting the bootloader updated, which means I was force to install it over ODIN 3.09 - use this bootloader NC2 BOOTLOADER (Thanks soloilmeglio for the bootloader)
2. I used CF-ROOT to gain root access
3. Then I installed CWM 6.0.4.8 recovery as recommended from antique_sonic (Updated few hours ago!)
4. Install the CivZ-SnapKat-Rev3.1-sm_n9005-4.4.2.zip kernel
5. Lets the phone reboot and check that everything works!
7: Boot into recovery and wipe system, data, cache, dalvik cache
8. Install the custom rom
Dont ask me why the kernel wasn't working from beginning and why it was "corrupted" after installing another custom rom - but now everything works as it should!
Thank you very much antique_sonic for helping me!

It could probably be a problem with TWRP as you mentioned earlier. After using CWM everything went smooth after updating my kernel. Last night I couldnt hold me back to try one more time, and I flashed X-NOTE with TWRP and I got the same problem as described in #1 post. Then I installed CWM and flashed X-NOTE again and everything got messed up. Then I restored everything, force installed the kernel and bootlaoder. After that installed CWM and then I was able to run X-NOTE without any problem.
I am not a professional developer but I may think that the problem is TWRP when it tries to flash the kernel under the process with may results in some problems. When using CWM from the beginning I do not get any problems but when using TWRP I need to restore everything back.

Bootloop after first restart with multiple CFWs!

Hi guys,
I have the standard note III 9005 and I had always installed CFWs on it.
I wanted to update to newer 6.0.1 Roms (had 6 roms before) but I seem to have a VERY annoying bug:
I tried to install Temaseks rom and resurrection rom but I had huge issues with it. I got bootloops although I got the newest 3.0.2.0 Team Win Recovery Project
I installed rom, GAPPS (correct version of course 6.0.1) , install rom again then delete cache and then it worked on both roms.
So a simple "install rom, GAPPS, then clean cache" didnt work. I tried to install multiple times until I got the installation! YAY! BUUUT!
Here is the fun part:
If I restarted the phone acidentally or on purpose I got stuck in a bootloop. After that the phone was unuseable again so the installation was useless.
Only solution is to completely wipe and reinstall and experiment with the order of installation until it works!
I did install STOCK rom because I was so freaked out and then went with ODIN the complete rooting guide for clean rooting, but still problem exists.
I tried two other roms but the problem was that while flashing the phone restarted automaticly and then TWRP said no installed rom? ???
Huge thanks for helping me!
New info:
I was able to make the rom work. I restarted and got stuck into bootloop!
I could boot normally after deleting dalvik cache!
But after rebooting I got into bootloop. Tried deleting cache again but this time it never booted properly.
How can I avoid by always deleting dalvik whenever I have to restart my phone (if battery dies or purpose)?
PPS: Stock Rom flash works flavlessly. I am waiting in stock rom until I find a proper solution :"(
Suggest you read the roms faqs and Q&A particularly with regard to TWRP .

How can I revert to factory state in my Leeco Le s3 (x522 US variant)

Hi friends! I really feel frustrated with this phone.
I began by using fastboot to flash TWRP (twrp-3.1.1-1-s2), used it to flash Lineageos 13.0, but IR BLASTER doesn't work, then I flashed 14.1 and IR blaster, Sim detection, flashlight and camera don't work correctly, I tried Resurrection remix and MIUI8 too but I gave up, neither of those Custom Roms works as I wanted them to.
So I went back to EUI and all was well until I wanted to update OTA, it gave me an error every time, tried to do it with update.zip but nothing, using stock recovery and nothing. I used TWRP and wipe everything again, now this thing won't start it just bootloops, I tried everything for two days and every time I use a stock ROM (5.8.020s) it gives me an error, or tells me it can't be read. When I factory reset and format everything it tells me I dont have an OS installed, so I'm completely lost I don't know what else to do and I can't return the phone because I'm overseas right now.
I really need to have it as when I got it the first time because at least it was functional but I just can't get it to work
I could really use some help right now :crying: thanks in advance guys!

So I managed to fix the problem. When you root this phone or in fact just flash a custom recovery like TWRP, it changes the model of the phone, If you unroot the phone you won't be able to receive OTAs anymore even if you are on stock ROM, you'll always get an error at the end of the update even if you do it manually, if you are dumb like me and didn't make a backup of your stock system, you won't find any help on the internet more than to install a custom ROM and learn to live with the errors and bugs. I did not want that so to be able to get the phone to its factory state, what I did was this:
1. Download: stock recovery image for Le s3 x522 (official, you can find it anywhere), LeEco_X522_5.8.019S_OTA.zip, bootloader-20S-s2.zip, twrp_s3.img (the chinese TWRP recovery) and S2_X522-NA-OP-IFXNAOP5802102141S-5.8.021S.zip
2. Save those zips to the root of the phone, obviously the .img files you are going to flash them through your PC
3. Put the phone in bootloader mode. command: fastboot flash recovery recovery.img (the official recovery)
4. fastboot boot twrp (the chinese one)
5. From this step what I did was pure luck
6. wipe cache and dalvik and install LeEco_X522_5.8.019S_OTA.zip
7. wipe cache and dalvik and install bootloader-20S-s2.zip
8. wipe cache and dalvik and install S2_X522-NA-OP-IFXNAOP5802102141S-5.8.021S.zip
9. Reboot
How and Why did this worked I don't know, I am a noob but please try if you find yourself in the same situation as I was, you don't lose anything with trying, if this doesn't work don't blame me, this worked for my phone.
Greetings friends!
Thanks for putting this guide together, I am in a similar situation in that I reverted to stock everything (1. Installed YDSS chinese twrp, 2. Installed S2_X522-NA-OP-IFXNAOP5802012141S-5.8.020S.zip. This flash was supposed to have installed the stock recovery and overriden the ydss twrp, but didn't, I had to manually flash that after. Everything came back smooth but my updates also failed at recovery.
I am wondering where you got the LeEco_X522_5.8.019S_OTA.zip, bootloader-20S-s2.zip & twrp_s3.img from?
Nice to hear you finally got it to work ! Aren't the X520 and the X522 the same phone ? Why official ROMs are not compatible ?
