urgent help! oppo a37f - Oppo A37 Questions & Answers

Hello people on Xda! I just bought a oppo a37f and it's was working okay until I turned it off, when I turned it off it just kept on going to bootloop. So I flashed many official firmwares using the Qualcomm tools and also the official tool for oppo. But everytime I flash sometimes it will come up with the setup screen everything works until 3 mins later it lags and sometimes have a black screen so then I force restart it (volume down + power) then it's the same again bootloop. I've really tried all possibilities that I could think of and hours and hours of researching on how to fix this. And I don't want this phone to go to waste.
So if you know how to fix this kind of problem then any advice would be good

Maybe it's a hardware issue

[Q] (S4 I9500) Stuck on Samsung Logo + Can't go to Recovery or download mode

First thank you for viewing my question and issue.
I'm new in here hoping to find a solution to my problem. I bought a used S4 I9500 last year it was lagging acting up slow did a search and read online that I might need to install better version via Odin (I'm totally new to the android world so I think I did a mistake here somewhere). So I did install I9505 version which I thought will work fine. (sorry for not doing enough researches coming from IOS which is less complicated). The phone apparently did a restart and got stuck on the Samsung logo which kept glowing for few minutes.
It was mid night by the time I was cracking this stuff out, so thought to myself to keep it plugged and go n rest for few hours. I woke up and the Phone was still stuck on the Samsung logo which was glowing not like paused or something. The phone was hot so i thought I should stop the whole operation before something worst happen. Did some searches and found that people are fixing this issue by going to recovery mode or download mode etc.
The thing is Vol+ and home button + power or Vol+ and power trick doesn't show the menu anymore. When i click any of these it just does a random reboot showing Galaxy I9500 logo and then back to the glowing samsung logo. notice that I was able to go to download mode and recovery mode prior to this issue but now I just can't for some reasons.
Would appreciate any help. Thank you
Find someone that can use Jtag maybe they can fix it.
Hard lesson for you. Never flash a firmware for another device onto your phone.
If they can't fix it, then you can buy a new phone. You bricked it.

First boot problem, stuck in bootloop

Hello, a friend of mine bought a moto x play black today, he buy it online, but the phone keep restarting itself after a few seconds of use and go in bootloop. We turn it off, turn it on again, it work for 20-30 sec and it restart again and go in bootloop. We made a few tries but we always get the same problem. There is a chance to fix it or we must give it back and ask for a refund?
Thanks a lot in advance

OPPO F1s Bootloop problem. Doesn't enter recovery mode.

Hello dear members!
I own an Oppo F1s and recently when I was using my mobile, browsing on chrome , it's display froze all of a sudden and nothing seemed to work so I pressed volume down + power button to hard reset my phone, thinking this would solve the problem, but to my surprise the phone turned off and then started restarting on its own not going past the logo screen. I thought it had soft bricked so I looked around on the internet and tried to find a tutorial to flash stock rom onto my mobile. I found one such tutorial where the uploader flashed stock rom onto his opps f1s using flash tool. I tried doing the same, followed all the steps but it kept giving me this error "STATUS_DOWNLOAD_EXCEPTION". Can anyone help me out as to what can be done at this point? I must also add that by pressing volume down and power button my phone doesn't enter recovery mode although it does say "recovery mode" in the corner but it doesn't move past that point and eventually restarts and then keeps restarting as before. Volume up and power button does nothing as well. Can this be a hardware issue? Also when I connect the charging cable, the battery symbol remains empty. The battery charging animation doesn't appear but just the battery. Any help would be appreciated.
P.S I am new to this forum so move this thread if its not in the right category. Thanks

this morning a friend of mine gave me his s3 neo with the same problem, bootloop, and no recovery, and no download mode, I put my battery, and I pressed for 10 minutes, continuously the power button, and in the end it was switched on normally, I went into recovery, wipe and I installed the firmware, after a custom rom, and the phone is fine, but if I put back the battery of my friend, restart the bootloop, it is the battery not the power button!

hi, do you dolve your problme? i guess i have the same problem XD
regards
My P10 plus started this exact problem today. Always stock, never rooted or boot unlocked.
I was playing a game and it rebooted. Started again and lasted a minute but then constant bootloop to eRecovery screen.
Did the erecovery image download and didn't do anything brought me back to the same screen
Tried to factory reset on the ecovery screen and then booted, but during setup it rebooted.
Went to fastboot screen (pwr+vol down while attached to usb) and rebooted after. I was able to go through setup.
After letting it for sit for only 2 minutes as I type this message, it randomly started rebooting on its own.....and now back to recovery screen.
FACKKKKKKK
UPDATE: Took my phone in to a cell repair shop after exhausting all my troubleshooting options.
They said they took the phone apart to disconnect the battery and do a full power drain. Then after reconnected they installed EMUI 9.1 again via USB and got the phone up and running.
Been working for me for the past 6 hours, but the phone just rebooted on me once, so i'm sure they're still an unsolved demon in it. but no idea what it is right now.... May be time to start phone shopping.
maybe just battery broken, install app accu battery or any other to check batery
