Hello everyone,
This is my first post on this forum, sorry in advance if the format is not correct.
Here's my problem: I was given a SM-J710FN that displayed an overheating problem on the screen while the phone was not heating at all, as well as buttons at the bottom of the phone were not working anymore.
I reset the device to factory default, erased the data from the recovery mode and flashed the 8.1 Oreo version with a ROM STOCK J710FXXU6CSK1
After all these manipulations, the buttons still did not work and the overheating message still appeared, preventing the phone from being charged even when it was switched off.
So I thought of programmed obsolescence, and thought it was worth trying to downgrade the phone to 7.0 from version 8.1.
Could you help me on this subject and tell me what you think?
Sorry for the up
try flash a custom rom, it does not need buttons, like this https://www.google.com/url?sa=t&source=web&rct=j&url=https://m.youtube.com/watch?v=veWLleEULe4&ved=2ahUKEwigx7TjmoTvAhVUIIgKHWbJCjIQ28sGMAJ6BAgFEBc&usg=AOvVaw3xJ6phS4kotjx4fk6Ypfuq
home button work or not
Thank you for the answer, I really appreciate it
Here is the update since I followed the Youtube link you sent me:
I have transferred the Custom ROM (Pixel-AB-11-20200909-ErfanGSI.img-0125.7z) as well as H-VENDOR_V1.0.zip to the mobile phone via a USB cable plugged to my PC in the root of the phone in order to proceed to its installation.
I then used Odin to flash Orange Fox (also TWRP on other attempts) with AP, but when I get to the Orange Fox recovery screen, the .zip files do not appear in the files. When searching on the Internet, it is advisable to flash via Fastboot, but despite several attempts, I cannot detect the phone with Fastboot, but only ADB. Even the manipulation saying to install the drivers manually from the device manager doesn't work because a message saying that the file to be used doesn't contain a driver is displayed. (android_winusb.inf)
And I also notice that after having flash TWRP or Orange Fox, the phone can no longer boot on the system.
Have you got any advices?
I continued my tests on my side, I was able to better understand how TWRP and Orange Fox work, in fact to make it usable, you first have to FORMAT the /data (not swipe), so, make TWRP / Orange Fox operational.
I was then blocked during the installation of the personalized ROM with the error of the /vendor, following my research, it would be necessary to install a .zip dedicated to that (Mokee from what I saw)
But I did something I shouldn't have done, and I flashed the zip "twrp-3.2.1-0-20180414-codeworkx-dumpling" from the Orange Fox recovery, and since then, the phone is stuck at startup, and when I try to access Download Mode, I get stuck at the Warning Message because my volume buttons don't react.
Is it possible to do something about it or the phone will be forever bricked?

Hello all.
I'm new to modifying my android (Galaxy S7 G930A) and could use some help. I have successfully rooted my phone, but have had some issues trying to flash a custom recovery. I was trying to flash TWRP but for some reason it didn't work, and I would always boot into the stock recovery.
Today, I screwed something up while trying to figure out my host of issues (I was also trying to figure out why I kept getting a "dm-verity verification failed" notice when flashing). Using the TWRP Manager app, I tried to install the recovery that way and it kept giving me an error that it was either already installed or encountered an issue of some kind. Knowing it wasn't installed, I looked for a different route. Long story short, I downloaded Flashify and then manually downloaded and flashed the TWRP recovery img and a "no-verity-opt-encrypt" file - which I read would fix the dm-verity error I was receiving.
I believe that's all I did before this recovery boot issue starting occurring.
Now, when attempting to boot into recovery (no matter what way, through an app, manually, etc) the blue text "Recovery Booting..." appears for half a second and then disappears. If I'm holding down the buttons it will flash again and disappear again, over and over. If I don't hold down the buttons, when it disappears the phone boots up as normal. So now I can't seem to access recovery at all. I wanted to try going the hard/factory reset route, but obviously can't because I can't access recovery.
Also, I don't know if this is related or not, but now my laptop will not recognize my phone at all. Doesn't give me any options - it will charge, but no connection. I was hoping to load it into Odin and do a stock reset to start from scratch before flashing a custom ROM.
Edit: I tested and connected to a different computer just fine, so there's obviously some miscommunication going on between my phone and laptop.
Can anyone help me out here? Sorry for the long post, I'm just really frustrated. :crying:
The title says it all, but I explain calmly how it happened.
I was trying to want to install the official version of LineageOS for my Zenfone 2 and after downloading all the necessary files, have formatted and clean everything (except the SD), trying to install the new custom rom and then have the same "error 7". Then I realized immediately that lacked the Bootloader for Marshmellow, so I tried to look for a ZIP file for this, being able to find it right for my smartphone. The folder was known as "M_BL_upgrade_for_zf2_ze551ml_6.0" and once I had entered the USB cable to my PC and started the "Upgrade.bat" program, after the strangely reboot bootloader returned closed (it was understood from the screen, which instead to be white background with black writing was black with white lettering), then I tried to go back in recovery mode, realizing that every time I tried to get in, it was as if I were locked in a deadly circle and then kept restart and then return to where we started ... you have any idea how to do it, maybe re-add the Recovery Mode standard via CMD?
I've had a problem with my phone since flashing Lineage and Gapps in TWRP, something went wrong, it's acting like I have a corrupted version of Lineage with only the basic functions, Gapps is not installed and I've lost root.
The phone is an Xperia Z5, prior to flashing Lineage zip I had successfully rooted the phone, i flashed Lineage and then Gapps, an error appeared saying Gapps had not installed (possibly because it was the wrong version). After that the phone went into a bootloop (Sony logo, battery icon, then restart with red light in the corner). I was able to turn the phone on by holding down the power button for 5 seconds and lineage started up as normal with just the basic apps, I have been using the phone for the last month like this unable to find an answer on the forum. If I was able to connect the phone to PC i could use flashtool to flash the stock rom and start from scratch, but it only charges even though i have usb set to MTP in developer options, it's not detected by PC no matter how many cables I try. Also, it will not install apps from the Play website, it downloads and says app is installed but app isn't shown in list of apps. Can't get into TWRP because it says device is not rooted. When I switch phone off it restarts again and goes into bootloop, have to hold down power button to start it up. I wondered if anyone was familiar with these strange symptoms and knew if there was any way out? My phones stuck in limbo until I can find a way of doing a hard reset but without being able to get into TWRP or connect phone to PC I'm stuck.
Hi people. Today I needed to install a file inside system/etc/permissions to enable OTG Host. Since I couldn't create a file there, I had the stupid idea of changing the permissions of the system folder. I changed it with root browser, to Owner: read/write/execute (the other stuff was unchecked). My phone turned off instantly, and now it wont turn on at all. Seems like I'm in big trouble. Still, I want to ask if something like that is recoverable somehow, and if anyone can point me in the right direction.
Phone: Samsuing A5
OS: Android 6.0.1
Root: Yes (systemless, with Odin)
Custom Recovery: No
Edit: I just connected the phone to my PC, and it detected a USB device called SAMSUNG_Android. It's weird, the phone seems to be off. Kinda gives me a bit of hope, but I'm a noob with these things.
Edit2: I waited a few minutes and tried to turn it on again. It worked! But now it boots to recovery, so it seems to be a soft brick. Factory Reset doesn't seem to do anything, I guess I'll have to flash a ROM. But I have no idea how to do that. Any help?
Edit3: With the help of a friend, I installed TWRP custom recovery, and used it to flash a Resurrection Remix ROM and GApps. However, I cannot make it reboot into system. It always goes to recovery. When booting, it shows the message "Recovery is not Seandroid Enforcing", and then opens TWRP recovery. I can see my device has a system folder with stuff in it, but I can't make it boot properly. Any suggestions?
I got my Nokia 3.1 in a bit of a weird situation trying to flash the stock ROM. I feel like it's a lost cause, but since I can still boot in recovery mode, there may still be a solution, I will explain in case someone can help.
It started when I tried to update from Android 8.0 to 10.0 (none of the previous OTA updates had worked and would always reboot in Oreo 8.0). This time, it didn't work and got the phone stuck in a boot loop.
The phone is still under warranty, but because I bought it overseas and there's no Nokia care centre here is New Zealand, I had no option but trying to repair it myself.
A wipe/factory reset didn't help, but after changing the active slot from B to A (using fastboot), it booted again in Oreo 8.0. Only problem is that I could no longer start a fresh Oreo 8.0 install without updating first and since all updates failed, I was stuck.
I suspect slot B is damaged or corrupt, hence the impossibility to update. To check it, I switched back the active slot to B after a factory reset, and that was not a great idea, the phone wouldn't even boot and looked hard-bricked.
But I still managed to use SP tool to download firmware, so I did that with the original Nokia 3.1 stock ROM (ES2).
However, I could not flash all files, I'm not too sure why.
I had the error message:
ERROR: STATUS_SEC_INSUFFICIENT_BUFFER
Verified boot is enabled
Please download signed image (sutinfo-verified.img) or disable verified boot
I didn't know how to do either of these, so I skipped the three problematic files: sutinfo.img, systeminfo_a.img, and cda_a.img (not sure what they do?).
It worked and un-bricked the phone, but it now boots to recovery mode only. What puzzles me is that I also no longer have access to fastboot, even when I reboot to bootloader (as if it skipped bootloader and went straight to recovery). I suspect it is because it still boots on slot B but I don't know how I can check that or change it back to slot A without fastboot access.
I tried using adb: adb shell getprop ro.boot_suffix but although it can see the device, it failed because it says device is unauthorized. I've tried all the fixes for this I found, to no avail.
So that's where I am, able to boot to recovery (but with adb unauthorized), able to flash firmware (except those files that must be signed), and unable to access fastboot.
I'm giving up hope that it's repairable, but I'd love to at least understand what happened, if someone has any idea...
Sorry for the long story...
