Hello guys.
Since there is no separate section for this device, posting it here as I saw others posting in this section.
My device, Lenovo Tab S8-50LC is automatically shutting down after sometime. Here are the patterns.
1. It all started when running YouTube app in landscape mode. As soon as you go landscape, it triggered a short splash screen of "Android System" and then it shuts down with shut down animation (the animation is laggy)
2. I tried to go to recovery mode to factory reset. But it doesn't go to Recovery. It just straight boots normally even after pressing Vol Up+Vol Down+Power.
3. I tried to reset after clean boot. Didn't do anything even after touching "Erase Everything" in factory reset mode. Then suddenly it shuts down and started erasing data. Then it boots again. This time, it was prompting me to enter the time and all of a sudden, it shuts down again with the shut down animation.
4. After some restart, it started working again but if under load from some app e.g Facebook/Instagram/Messenger it starts lagging and shuts down showing the "Android System" splash screen and shut down animation.
So, what could be the problem?
Device Information:
1. Android Version: 4.4.2 (Stock, Non-Rooted)
2. Software Version: TABS8-50LC_150113
3. Intel Quad Core version, RAM-2GB
4. Current Firmware: S8-50LC_S000193_150113_ROW
5. Kernel Version: 3.10.20
6. Build Number: TABS8-50LC_S000193_150113_TELEK
Thank you very much!

Hi! All. My phone started acting wierd last week. It randomly shuts down & reboots & gets stuck at the black screen with the name & model no. I tried taking out battery & putting it back but after a few days, the problem returns. Btw my set is rooted on stock rom. Any ideas how to solve?
try booting into recovery (vol up+home+power) and factory reset
Ok, so one night I was using my phone normally (Browsing. Watching YouTube, Playing Games) like everyone else does. Then all of a sudden it shuts off, but immediately turns on again without me pressing a button. (So basically it suddenly auto restarts on its own) This occured maybe 2-4 times (all in one night) until one time, it shuts off but doesn't turn on again (basically an automatic shutdown), so I tried turning it on again (Power button), then I got shocked because all of a sudden it enters a boot loop (Screen displaying this sequence : Samsung Galaxy S4 screen, my carrier logo screen, The encrypted screen (where you have to enter your encryption password) then again the Samsung logo but this time with the colors splashing from the background, then it shuts off again.) Sometimes after the boot loop sequence, it vibrates but never turns on again, sometimes it just turns off after the sequence. And as I try and try to get away from the boot loop, the sequence became shorter. So I'm guessing it's a battery problem, BUT my battery isn't bloated or deformed. I tried clearing the cache first, again the sequence got shorter (never going up to the carrier logo screen), then I tried formatting the data, still to no avail. Now, when I turn it on, It shows the Samsung logo screen for 2 seconds and shuts down.
I tried flashing it with ODIN thru Download mode BUT (HERE'S where another problem occured) :
My phone never get pass on the system.img.ext4 dialogue and my screen just goes blank. But ODIN still recognizes my phone. And when I remove the USB cable, ODIN says FAIL.
I'm sure the cable is working. I downloaded the firmware for my carrier (Tre 3).
What could be the real problem here?
Here is the description of my device :
Samsung Galaxy GT-I9505
Bought from Italy, Tre 3 carrier
Can I download a different region/carrier for my I9505 phone?
Advanced thanks for anyone who comments and I'm very sorry for my English. Thanks!
I would install TWRP recovery, boot to it, and use it to format data, which will remove the encryption. Then I would either push a rom to the phone via recovery or try to reinstall the stock firmware with Odin. Make sure that you run Odin as admin as well. The firmware must be the same version or newer. If you still have the stock recovery and can boot to it, then I think the build number of the currently installed firmware will be visible there. You should be able to use that to Google the correct version you need.
Hey it's me. Just posting a quick reply.
Thanks for replying to my post. Yesterday I successfully flash a rom to my GT-I9505 (Version 5.0.1 Italy HUI 3G). However it still didn't boot up. At first try it booted up to the first setup screen then just randomly shuts down. Then as I try to boot it up again, It just shuts down after the first Samsung logo (with the GT-I9505 logo), I can't boot into recovery cause it shuts down. I'm sure it's not a battery issue cause when I boot into download mode, it can stay in that screen for like 10 minutes. What could be the issue? I'm planning to disassemble my S4 sooner to see if something's wrong inside. Thanks again for the reply
I recently flashed Lineage OS 14.1 based Android 7.1.1 for SG3. everything worked fine at the begining a few days later i tried to boot on safe mode. So i press power button and keep pressing of "POWER OFF" until it pops up a text says ("safe mode will disable all third-party...) and then i clicked ok but when booting it doesn't boot the system so it stucks on Samsung Galaxy S3 screen (logo) and then it turns off itself. I also tried pulling up the battery for a while but it didn't work, the rom is official from lineage page.
PS: i flashed the rom twice after this problem happened but i boot again to safe mode and the same scinareo HELP ME PLEASE!
Apparently keep tapping menu as you boot up.. Failing that go back to stock via odin and start over.

Hi everyone, I just received my Teclast M30 (10-inch tablet), version M5P3. I tried flashing a custom ROM but - surprise - I'm stuck on a bootloop.
The stock ROM was an Android 8 version. It is not rooted.
- I went into the developer options and allowed Bootloader unlocking via the corresponding option.
- Then via fastboot, I unlocked the Bootloader via (without any error):
Code:
fastboot flashing unlock
- Flashed TWRP, found on the only Teclast M30 thread... (=> https://forum.xda-developers.com/showpost.php?p=81064235&postcount=56) via fastboot (without any error):
Code:
fastboot flash recovery twrp-3.3.1-teclast-m30-20191201.img
- Flashed a GSI (ARM64 A-only) ROM (without any error). I used the "Android 9 - Havoc-OS v2.9" ROM on this link => https://github.com/phhusson/treble_experimentations/wiki/Teclast-m30-(MT6797x-helio-x27))
Code:
fastboot flash system Havoc-OS-v2.9-20190914-phhgsi_arm64_a-Official.img
I realized after a few hours that the TWRP I used was for the M4P7 version and mine is M5P3.. so I now know what I did wrong but even with this info, it doesn't help for my problem.
When trying to boot after flashing, I'm stuck on a bootloop.
It shows the Teclast Logo with some text saying it's in Orange State (= show a message saying the is bootloader unlocked) and then go to a screen with an Android Logo and a message saying: "No Command".
This "No command" screen is well known in our forum BUT problem is this screen stays only for about 3 seconds, and then the screen become black for 1 sec, then the "No Command" screen appears again for 3 sec, then it disappears again, endlessly. Here is a video of what's going on https://www.youtube.com/watch?v=O1iiu6MtOyM
Pressing "Power & Vol+" or "Power Button & Vol-" on this screen does nothing, I just can't enter fastboot mode as it keep looping and do not stay on the "No Command" screen.
When the tablet is completely shut down, I tried powering it up pressing just the "Power" button, but also "Power & Vol+", "Power Button & Vol-" but it does the same thing every time. It also acts identical whether the tablet is plugged in to the computer or just charging on the wall plug.
There is a "Reset" button on the tablet (must use a SIM pin to press it) but it seems useless to reset the device. When pressing it, it only shut down the tablet and stops the loop. I tried pressing it for long periods like 10-20-30 seconds in different situations but it just shut down the device and do nothing.
Does anyone have any leads on what I can do to revert back to original state or even just access fastboot mode ?
Thanks
I have the factory firmware file for my tablet (the good version this time..) now, but still the same problem of looping...
For future reference:
I fixed it thanks to the stock firmware and a tool (SP Flash Tool) that are both included in a file package provided by the constructor (at the time I created this post, this file didn't exist on their website. Now it does ).
This file is hosted on Baidu (only accessible with an account, and you need a Chinese phone number to create one) so I uploaded it on Mega if anyone need it:

Bye!
I have a galaxy A7 2018 (SM-A750F) that I wanted to root. I flashed the specific TWRP recovery .tar file for my device using Odin, but I pressed the volume up + power key before the success message appeared on Odin. Now I'm stuck in a TWRP bootloop when the homepage of the TWRP mode flashes (basically just the logo and the version number) for a few seconds, then a black screen appears and the phone reboots back into the same mode when I press volume down and power keys. Eventually, the TWRP homepage screen flashes on and off and the logo appears to be distorted.
I tried accessing my phone using adb, but it shows that no devices are connected, and I made sure to enable USB debugging before the whole process. Could the usb port have been damaged because of the process? It was 100% functional.
My phone is also overheating, even when it is turned off.

I don't really know what to do at this point. I even tried tapping on the black screen but no short vibrations occurred, so I guess the whole TWRP mode is corrupted. Any help would be best welcome!
