Please help me, I have a bootloop - Samsung Galaxy A7 (2018) Questions & Answers

I have sent my smartphone to the repairment store and it was frustrating. They haven't solved my problem with screen constantly turned on, looping at the Samsung logo.
Do you guys have any solution for this problem? Do I need to replace the motherboard (I mean, memory chip)?
Please help me and I will be happy

can you go into recovery?

Your phone is soft bricked. No need to change the motherboard.
Just flash the stock firmware using odin tool.
To download firmware use samfirm. Visit https://samfirmtool.com/ to download samfirm.

Just tried Samfirm tool, and my phone is now working! The only thing I needed to do before it is to open the device's back cover and reconnect the battery connector and then put it to download mode.
I did NOT need to change the motherboard

no need to open the back cover also, just hold volume down + power to hard restart, after that hold vol up + down and slot in the usb cable with pc then you will able to go into download mode

I'm facing the same problem after flash to the same rom, by the way what you tell the store then they replaced a new magic for you?? Because I'm thinking go to service center due to no solution to solve this issue.

Galaxy Tab 2 won't start

Hi!
I'm new to flashing and tried to install clearRom in my P3115. The problem is that after reboot, the tablet wont start!
If I tried to connect it to the pc, drivers is nos installed / recognized and the batery logo appears but never charges. It show as is it is empty.
I can´t start it neither or access download mode or CWR mode. Odin does not recognize it neither!
Please, help! It's like dead!
Thanks a lot! :good:

Thanks for the tip.
I just used Odin to flash clear Rom like explained here:
theandroidsoul cleanrom-custom-rom-for-galaxy-tab-2-10-1-guide/
Everything seems to be fine, but after restart nothing happened. I noted that if you plug the tablet to the usb port, it keeps looping the sound as when any usb is connected. Over and Over again.
It never starts, not even the Samsung logo. The only thing it does is, once plugged in, I can see the battery charge logo, but always empty.
Please, help!!
Thanks!
What kind of message do you get from Odin if you try to connect it and load a ROM? My tab was stuck also but I was able to get Odin load even when it looked like it was connecting.

Odin never shows the ID:COM PORT rectangle as connected or colored!

Not sure, what problem you face exactly.
This is what i understand, you get a battery logo while your device starts and wont boot up right? If yes, try these steps, might help you.
1. battery logo you get in the boot thats because, you have connected USB Cable to computer/Charger.
2. Make sure you have charge in battery so that while doing below steps, would be a problem.
3. Once you find, it has a enough battery charge you can disconnect the cable safely (If not place it for a wallcharger, untill the battery logo fills up the juice and you find it as charged completly)
4. While booting Press the POWER+VOLUME DOWN for Download mode.
5. Now connect your tablet to PC which has ODIN and sufficient drivers installed,
6. ODIN should detect to flash the ROM.
7. Download extact Firmwares from Sammobile site / from XDA links, which is suitable.
Hopefully it should bootup with no issues.

Dear nagabushan, thanks for your help!
I think the problem is battery related, cause the icon never fills up. It's like it cant charge batteries! The juice never even apears!
I'll leave it plugged in to the wall for a few our, and see what is going on.
I'll be back in a few hours!

Thanks jonttuv. Actually, after 6 hours, the battery juice is the same.
I'll check in the forum about this procedure.
If you already know anything, Can you please provide a good step by step to accomplish this?
Thanks in advance to all.

This is just a guess, but i think that there is no JTAG unit(that is just plugged to the tablet and DOWNLOAD MODE ) There is a method that can be extremely dangerous.
This method is to open the tab, take the motherboard, find the correct pins and flash JTAG. I DO NOT TAKE RESPONSIBILITY FOR THIS METHOD NEITHER DO I SUPPORT IT!
The second method is to take it to the warranty. Download mode is not accessible so they can't tell if it's rooted, custom rom or anything like that. They will either send you a new device and voilá. That's it. Or they try to fix it. Google samsung galaxy tab 2 jtag. It will help you if you prefer the first option.

Galaxy S6 bootloop

Hey experts so i have the S6 gm-920F i updated OTA and now the phone doesnt recognize the fingerprint and forgot the password so i install TWRP 3 via odin booted the recovery and transferred my data successfully then I made a factory reset to delete the passcode to be able to use the phone after making the reset and pressing reboot system it gets stuck in the recovery the system doesn't reboot so i tried hard rebooting the phone is stuck on black screen that says samsung galaxy s6 and restarts restarts restarts (bootloop) i tried reflash the 6.0.1 bootloader no luck then flash 5.1 bootloader flashed philz recovery then 6.0.1 bootloader still nothing! Did i damage something serious ? does a fresh firmware install through odin bring my phone back to life ? Thanks in advance
Please try a fresh install of Firmware. Install MM bootloader and modem first with TWRP MM compatible recovery and download an extra lite MM rom to see if your phone will come back to life, (using extra lite package is less of a download than a stock 2gb download)
TWRP is what gave me the problem once i enter i can exit from there ! i got the stock firmware tried to flash using odin then get fail! please can you give a noob some simple instructions with links ?
Hi mate, Try flashing through ODIN a TAR image for your phone version. You can find a TAR on a website such as sammobile. Once you have download the tar put your phone into download mode by pressing and holding Volume Down, Home and Power keys at the same time. Start ODIN and connect the phone to your computer, click AP and browse and find the TAR file you downloaded. Then click start and it should flash back stock firmware for your phone.

Another Solution i have is to try Samsung Smart switch software. That might solve your problem, I have used it before when I was stuck .

I can't promise that you haven't, however it is extremely hard to hard brick a phone these days. There are many ways to try and restore it to previous condition not all of which I am familiar with, if this doesn't solve your problem keep scouring XDA for an answer, undoutably a more skilled dev will be able to help you

Samsung Galaxy S6 Stuck on Samsung Boot Logo

I was trying to root my phone, and it passed, then wouldn't go past the boot logo. So I tried to flash my phone to a stock rom, but I accidentally used a rom for a different build. My phone's build is G920AUCS4CPG1. I can't find a stock rom for my phone, and I can't get it to go past the boot logo, even after getting into recovery and trying to delete the cache and factory reset the phone. Please help asap. Btw carrier is AT&T
EDIT: Had it plugged into a charger, guess it's not charging now? It's hooked up and it shows the battery icon but it's empty and not recharging. Buttttt, if I unplug it from the charger and hold the power button and volume down, it turns off and goes back to the samsung logo.

I recently fixed a bricked XZP with Flashtool, get the latest stock firmware from Xperifirm if you dont have on hand an older hackable firmware from XperiFIX
in Xperifirm setting, set it to extract firmware automatically once downloaded to speed things up,
In flashtool/Tools/bundles/Create, select source folder (your downloaded extracted firmware)
in device "double click" & select your phone model from the list.
branding: add as your download example, custom_uk
version: firmware version copy & paste from download
copy all files from file list to firmware content & click create
this will build a .ftf flash tools file which can then be flashed to your bricked device
just follow the prompts in flashtool....
worked for me,
good luck

Ofcourse i have and flashed .34 amd .75 frimwares with both neflasher and flashtool but none of them fix my problem.is it something that dosent change when we flash stock frimwares.
Lol. Sony phones are really hard to brick. You really can't brick a Sony phone even if you intentionally wanted to. I've even had a failed flash (phone disconnected while flashing) and was still able to flash using flashtool.
Anyways, I know this has been said before, but what happens after you flash using flashtool? Did you check all the boxes for a full wipe?
BTW, bad mouthing a phone just because you can't solve your problem won't help you.
