J4 plus (J415GB) bricked - Samsung Galaxy J4+ Questions & Answers

Is there anyone here facing same with my situation? today i bricked my J4 plus, Dunno if its hard bricked or soft brick, I can't enter to download mode and system restore anymore. Im just trying to get oreo back because i fell little laggy on my current os (pie). I went to samsung service center and they told to use JTAG to get it fix but its too expensive for me to pay hundreds buck for this.
Thank you

its not bricked. your battery is full drained. i had the same problem and how i fixed!!! i presed all 3 buttons and put usb cable to my pc and my phone. it goes like bootloop starts and shuts. you will wait with pressed buttons from 5 to 10 mins depend how low is your battery. and finaly will go to download mode and you can flash it then!!!

Bricked my J4+
Can someone help me with a bricked J4+?
I wanted to install TWRP, I followed the guide to the letter on how to install TWRP.
After successfully flashing TWRP 3.2.3-0 and flashing RMM bypass zip (without booting to the OS) I also performed a Wipe Cache in TWRP.
I booted to the Samsung OS and the system overall felt laggy.
I performed a Factory Reset, still the system felt laggy.
I decided to use Odin and install the Samsung factory system (thus go back to Samsung OS).
I booted successfully and decided to give TWRP 3.2.3-0 another chance.
Odin resulted in FAIL when trying to flash with the following error: Can't open the specified file (line: 1892)
I tried different versions of Odin (from last to previous ones), different USB ports, I even tried another PC but no success.
I performed another factory reset and now the phone is hard bricked I guess because it will power on...try to get in stock recovery and Erase...and then power off. I can't get to download mode or stock recovery.
Any help I would highly appreciate it.
Thanks.

you didnt follow guide from letter to letter. is obviuosly you didnt do all you need to do. if you in pie update you need to flash twrp (you did) then NEED to format data(go to wipe choose format data(not wipe data,cache) write yes and swipe to format data.this step is important.then go to recovery again and flash pie patched boot.img and oreo enforcing.zip,then RMM bypass,and then you can do boot up your device.thanks.

The part where I had to format the data...I have missed that. Thanks for pointing it out.
I took the phone to a repair shop because it is hard bricked and it needs jtag to unbrick it.
As soon as I have it back I will try again to install TWRP.
Thanks for the help, I appreciate it.

This is a phone from work and I did toggle EOM unlock and USB debugging in order to flash TWRP.
I did not enter any password, face unlock, pattern or sign in to google....nothing of the sort. As soon as I opened the phone from the box tried to install TWRP knowing it will erase everything after TWRP installation. I really hate Samsung UI and wanted to try Lineage OS or another custom ROM which is not laggy like ONE UI.
After installing TWRP the phone became very laggy (obviously I did not perform a format data...my bad) I did use Odin and flashed the corresponding firmware of the phone and it did that successfully.
I tried to give TWRP another shot by flashing it again but I was getting a FAIL in Odin with the following error: Can't open the specified file (line: 1892)
After this I tried to flash again the same Samsung firmware but kept getting the same FAIL and the same error: Can't open the specified file (line: 1892)
I have tried all versions of Odin but the same FAIL and same error.
Now I can't even get into Download mode or Samsung recovery mode.
I press Volume Up + Volume Down and insert the micro USB cable....the phone takes at least 10 seconds to power up (Samsung logo) and then I see a blue screen with Android robot trying to perform an Erase and then fails and the phone powers off immediately.
As soon as I get the phone I will check your link on XDA and try a GSI ROM.
Which one do you recommend...this is a work phone, all I care about is speed and fluidity and it has to be a daily driver.

yeeeahhh. i am knowing that in hard way. you can check user data only if you have ORIGINAL firmware and not rooted phone(mean twrp),if you have rooted(twrp) then flash with or without user data. some firmwares on web can flash with user data, some cant.anyway as i say you can always ask for help.i will gladly help if i can. good luck.

What you're describing are symptoms of a flat battery and a direct boot to recovery.
To boot to download mode plug in the USB cable first then hold vol up, vol down and power until download mode appears.
There is absolutely no way TWRP caused the lag. TWRP runs in its own minimal OS environment and has no effect on a booted android OS whatsoever.
Lastly your device wasn't hard bricked, a device that powers on even if it doesn't boot is only soft bricked.
Usually recoverable using the right procedure.

I managed to boot into the Revovery and perform a factory reset, now the phone booted normally.
I will try and install TWRP.
When these strange things happened the device had over 80% battery...at least that's what it showed on screen.
Now I see that indeed it was flat 0% and you were right to point out that this is a flat battery problem.
Thanks for the help I really appreciate it.

Yes Thanks. I am at 100% battery. Can I ask a few questions on how to install TWRP?
I am on Android 9.x.x PIE.
Install TWRP and immediately force reboot to recovery.
Flash the RMM bypass.
Format data
Boot to Samsung OS.
Is this procedure correct?
Thanks.

It's correct, but if you want access to the data partition in twrp you need to also install the encryption patch.
You will also need to either install magisk or some other patch that disables dmverity.

[Q] Can't reboot system without going through fast boot.

Like the title says, my Nexus 5 won't boot unless I manually plug it in, hold down volume buttons and power, then wait 15 seconds for fast boot to appear, and then select "start."
Thats the problem. Now for some more information:
1. Nexus 5 32 gb
2. ROM: CM 11 Dec 13s Nightly
3. Kernel: Bricked 3.4.0
4. The phone is totally functional. The only thing wrong with it is that it can't reboot. From the system, TWRP recover, or anything, it simply will not reboot. Every time I must go into fast boot then press the power button when it says "start." After this, the phone works just as I would expect it to. I can still flash kernels and backups through recovery, it just must be restarted manually through the fast boot. This is a problem for me because I don't always want to have to plug it in when I want to reboot it.
When did it start:
Let me start off by saying that I thing the root of all my problems was the TouchControl app that allows the knock to wake function to work. I downloaded the app and was told to install the developers custom kernel. I did and not only did the app not work, it also seemed to brick my phone. I was scared, but, after doing some research, I found the method of plugging it in and holding down all buttons for about 15 seconds and my phone was saved. Ever since then there has been the problem. I must always do this to reboot my phone. Since the app didn't work I decided to install the Bricked Kernel and everything went fine except that I wasn't prompted with the interactive installer. The kernel works fine and I am now using the Knock to wake feature built into the kernel and am very happy.
Seems to be caused by swipe2wake aka knock 2 wake aka knock knock (but not totally sure)
What I've Tried (don't assume I've tried something I haven't. I could have missed something obvious.):
1. Resetting permissions through TWRP (just thought I'd try)
2. Putting back CM 11 Kernel
3. Restoring to a time when my phone did restart
Any help would be greatly appreciated. I will try to keep the original post updated with everything I try.
FIXED with the help of jd1639 and meangreenie
------------------------------------------------------------------
1.Follow jd1639's link in 3rd comment to the page and
A. Install adb and flashboot drivers
B. Install your version of factory images from google (if you are running 4.4.2 get the image for 4.4.2)
2. Plug in phone to AC CHARGER and hold down power and volume buttons for up to 20 seconds. This should put it into fast boot mode
3. After getting phone in fast boot mode, plug it into your mac or pc.
4. Out of all the instructions in the "How to flash a factory image" thread go to method 2 and ONLY DO THE FIRST TWO LINES OF CODE. All that needs to be flashed is the bootloader.img
5. After it says complete and your phone restarts you should be able to push "start" on your phone and be good!
I would try and fastboot flash boot boot.img. where boot.img is the boot image from the factory image.

Thanks so much for trying to help. I installed all the things and flashed Boot.img from fast boot, but once I restarted my phone everything was messed up (booted to home screen but basically the system started failing). After this, I retried but deleted my cache and delvik cache. This time the system simply wouldn't boot. Luckily I backed up and restored to my previous version. Thanks for trying, but this did not work.

Were you on 4.4 or 4.4.2. Sounds like 4.4.2. The factory image in the link was 4.4

try reflashing via custom recovery or fastboot.. bootloader, recovery and suitable boot.img for your rom, maybe give the radio a reflash too

no it won't delete your data.. but please triple check your files and fastboot commands before executing
the last resort is to format data if all else fails
Thank you both so much. I have (with both of your help fixed it). I will post how in the original post. Thanks again.

Phone broken because of TWRP change file system

I used a video on youtube to install TWRP on my galaxy s7 (SM-G930F)
Almost everything worked fine, except I was not able to make a backup. I got the error "Unable to Mount /data". A lot of videos told me that I need to 1. wipe 2. advanced 3. change filesystem 4..exFat and then EXT4. I tried this method, but TWRP froze after some time during the exFAT change process. Now my phone tries to boot into recovery mode, but won't go further than the very first screen of TWRP (where you see the version number and the logo).
What should I do now? I tried to reflash TWRP, but it still doesn't go past the very first screen. I am also not able to turn off my phone, because it keeps rebooting into recovery mode. I think that I need to find a way to change my filesystem to EXT4, but I cant do that with TWRP.
Can somebody help me plz (and sorry for my bad English)
press vol down + home button + power button to boot into download mode and reflash stock rom.

I just tried this, but it does not work.
Odin says that thread has successfully flashed all the files. My phone is installing the software update and erasing, but after that the screen is black. I cant boot the device or even enter recovery mode (download mode still work). I tried both flashing CSC and HOME_CSC, but both didnt work.
What should I do now?

The same thing happened to me. Keep trying to access the TWRP even if it takes a bit longer than an hour it will enter. You do not have to do anything else, just keep trying, when you access, you'll be able to repair the partitions, change them to fat32 instead of exfat, and then return to EXT4. It will work.

I need help. I relocked my bootloader, and now my phone (OP7P) won't even turn on

So over the past day I had rooted my oneplus 7 pro and all was going well until I decided to delete the netflix stock application. Then I restarted my phone from holding the power button and pressing restart and then I booted into fastboot. Everytime I pressed start it would send me back to fastboot but I was able go to twrp recovery. Stupidly, I wiped the whole phone thinking I had no other options. Then after that, I found a setting in advanced that allowed me to leave recovery mode I think? Whatever it was, I was booted back into the oneplus start screen and reset up my phone. Then I tried to re-root my phone and couldn't get it to work because it said the magisk zip file was corrupt. Then I just decided to give up and go back to stock.
Little did I no, you are NOT supposed to relock the bootloader, because that is exactly what I did. After doing that, I got a message saying my phone was corrupt and I looked up quick solution and it said to press my volume buttons and power buttons. Now my phone won't even turn on. I am freaking out right now, knowing that my phone is probably bricked and I am going to have to pay probably a third of what I even paid for this phone to get it fixed. When I plug my phone into my pc the device is shown as "QUSB_BULK_CID:0404_SN:3BB285D7". If any of you guys can help, I'm all ears.
edit: I meant I locked oem/bootloader. Also, I got the phone to power on. It is in a bootloop where the oneplus logo shows up and then it gives me the message "Your device is corrupt. it can't be trusted and will not boot"
edit 2: After two hours, I finally fixed it. I downloaded the MSM tool and found the qualcomm drivers and after a few trial and errors, I finally got it to work

U probably should have flashed stock firmware before relocking the bootloader
As long as you can boot into fastboot you should be good. Make sure you have correct drivers etc etc. Boot into fastboot and just boot into twrp, don't flash. Wipe data, system, vendor, dalv, cache. Recheck on what to delete and what order because it has to be the correct things and I might be mixed up off the top of my head, delete them in twrp. Then boot back into twrp after all that and reflash your custom rom. Take note if your ****s bricked you wont be able to install the zip via regular twrp swipe, you will have to use twrp sideload feature with adb and install from pc and install it that way. If that doesn't work at all just do a complete reflash of stock firmware via fastboot. Reflashing custom should work though I got mine out of a brick this way. As long as fastboots working you can get out of anything. Also Linux is 100x better than other OSs for this stuff.

OK here's the order. Boot into twrp, don't flash.
Wipe -> ADVANCED -- select system + vendor -> SWIPE TO WIPE
reboot bootloader
fastboot boot back into twrp
-- then --
Format data, Wipe cache & dalvik-cache
Flash ROM.
Then reboot system. Boom.
Remember you will most likely have to flash the ROM via sideload. As transferring will not work in a bricked phone.

As long as you can boot into fastboot you should be good. Make sure you have correct drivers etc etc. Boot into fastboot and just boot into twrp, don't flash. Wipe data, system, vendor, dalv, cache. Recheck on what to delete and what order because it has to be the correct things and I might be mixed up off the top of my head, delete them in twrp. Then boot back into twrp after all that and reflash your custom rom. Take note if your ****s bricked you wont be able to install the zip via regular twrp swipe, you will have to use twrp sideload feature with adb and install from pc and install it that way. If that doesn't work at all just do a complete reflash of stock firmware via fastboot. Reflashing custom should work though I got mine out of a brick this way. As long as fastboots working you can get out of anything. Also Linux is 100x better than other OSs for this stuff.

Question No Download Mode - bricked S21+

Hi,
I've managed to brick my S21+, after a mistake during flashing of a newer twrp version with Odin.
I basically placed the (patched) stock AP file in the AP slot instead of the TWRP tar, and the vbmeta_disabled_R.tar in the userdata slot.
After reboot, I got a boot loop, and I am not able to boot to recovery or to download mode as before when using the key-combo.
Previous to this flashing, I had the TWRP 3.6 and Lineageos 19 GSI for about 6 months, with no issues.
My question - how can I get to Download mode now? and is it possible that I ran over my recovery?
Is it possible that the download mode is no longer available due to the AP flashing (no BL, CSC files)?
Appreciate any suggestion and help!
connect it to the PC and do the combination that you did before, that is volume up and volume down pressed at the same time, that same thing happened to me, when I wanted to update twrp better install the stock first and then the new recovery, so you take advantage of updating the firmware of the phone and the new recovery
Strangely, the recovery entry or download does not work without being connected, so I recommend you better install the magisk to enter the recovery from there, otherwise you will have to do that process when you want to update or install custom roms

Thanks for your reply!
the key-combo in S21x are with USB plugged to PC, otherwise recovery cannot be reached, unless using ADB command. I have tried this many times since the wrong Odin flash occurred, but nothing happens except from reboot, warning screen (about unofficial software) and reboot again.
Even previous to the bricking, typically in order to get to download mode in this device, you need to go through recovery first and then select download mode. Alternatively, adb reboot download command, but neither are now an option.
So my last resort was a USB-JIG device to get to download mode - but I don't know of any such device for a USB-C connection.
Anyone here has experience with that? or can direct me to such a device for the newer Samsung models?
Thanks!

Thanks for your help! - indeed the PLUS and MINUS volume keys with the usb cable plugged in gets you directly to d/l mode. I just tried it with the power key all the time, as in previous models, and that got me nothing.
Issue solved!

Question samsung a536E stuck on bootloop

hello everyone, today i tried to flash twrp on my phone (rooted with magisk and running stock samsung rom), the flash was successful and i was able to boot into twrp but i coudnt access my storage or anything else, so i saw a guide saying to change the filesystem to ext2 then ext4, after i did that i could access most of the other folders but not the storage foldier as it still showed 0mb. i thought i just need to reboot my device to fix the issue but now im stuck on a bootloop. i cant poweroff the device since no button combination is currently working. is there anything i can do to power it off or do i have to wait a few days till the battery drains to 0?
[RECOVERY][UNOFFICIAL] TWRP for Galaxy A53 5G (Exynos)
Team Win Recovery Project 3.x, or twrp3 for short, is a custom recovery built with ease of use and customization in mind. Its a fully touch driven user interface no more volume rocker or power buttons to mash. The GUI is also fully XML driven and...

this is the link i used to flash twrp except i didnt follow the wipe instructions because i dont want to use a custom os.
and if nothing else works and i have to wait a few days till it drains to 0, will i be able to boot back into samsung's recovery mode or is this device hard bricked?
help will be greatly appreciated.
This phone doesn't have the nice feature of holding the power button for force off so that is a negative here.
I don't think you should have edit:changed the partition types. If that was necessary it would be a ridiculous thing for other Android roms to have to do. Its all Android so should have worked without that.
Its unlikely that anything new will result from a cold boot verses a warm boot. Worth a shot I suppose but don't hold your breath. Expect nothing new.
If its stuck without Odin, fastboot, ADB, all buttons not doing anything, can't ingest and do something from sd card, can't show up via USB on computer, etc with nothing at all then its totally finished since nothing can be done. Consider it a loss and learn from it.
I'd like to also state that there are for some reason people who supposedly bring roms over to devices and they don't have the device so therefore don't really know if it works or not. You have to be careful about the guides you follow. I've seen someone try with a device that could not be unlocked ever for anyone and that person thought it would work. Live and learn.

hello, i was able to boot the phone into twrp and do a factory reset, i had to time the vol up + power button at exactly the time when the screen went black and it worked!. but now i have a question, if i want to get twrp again and i dont plan to flash a custom rom like it says in the guide, how do i get twrp to recognize my storage? and do you flash twrp before installing an os or after because ive done it after installing the os.

yeah so it seems like the issue isnt with changing the file system or anything because i installed twrp again and tried rebooting and i got the same bootloop issue, but if i flash a rom then ill lose twrp like it happened last time so i dont understand what im supposed to do
you have to format data in twrp otherwise it won't see your storage folder.
once formatted reboot to twrp then reboot to system, it should reboot to stock rom and the set up pages.

wipe>format data>type yes>reboot to recovery. i did that and still cant reboot to system bootloop issue persists
yes you did it correctly this time, is there anyway to undo your 'filesystem to ext2 then ext4'?
or maybe you have to flash the custom kernel to get it all up and running again

Try a different version of TWRP I remember this happened to me before and I installed a different version and it was fine
