Tecno G9 reset issues - Android Q&A, Help & Troubleshooting

my tablet have been having issues, so i tried factory resetting it. Instead of resetting, it opened recovery mode. so i reboot it and it goes back to the same state it was before. i try to reset again, this time i perform a hard reset myself, nothing changes. goes back to the same state. i then flash it using sp flashtool and no changes occur it boots back up to the same state as it was before. i try to erase remotely using find my device and still the same thing happens, but now it keeps unmounting and erasing on reboot so there is this loop that is occuring every 50 seconds after reboot. please help.

[Q] Sudden crash and then bootloop, how to fix ?

I just flashed I9300XXEMA2_I9300NEEEMA1_NEE and cf-auto-root. While i was setting up my phone, freezing some apps in Titanium backup, it crashed to a black screen with the notification bar visible. I had to pull the battery and now when i reboot i get stuck at the last Samsung logo in the boot process.
I can enter download mode, but not recovery. I`ve tried reflashing the above firmware twice( with Odin, no errors), but still stuck on Samsung logo.
Any way to revive my phone ?
Thanks
after reflashing, if it succeeded, go to recovery and do a factory reset
Cheers
I couldent enter recovery after flashing just the firmware, i just tried flashing cf-auto-root again wich did the trick.
I did a factory reset and its now booting again
Thanks again
wipe cache and dalvik and factory reset

Samsung Galaxy S2 not booting

I rooted my phone without any trouble for months, and its been working just fine, until now! Then, I had to do a factory reset. The normal procedure, SETTINGS> PRIVACY> factory reset. The phone then never got past the boot logo. It starts to load, and just gets stuck at the Samsung logo, and nothing else. there's two lights glowing from the capacitive buttons, and that's all. I'm on 4.1.2 JB stock rom. Later, I tried to enter recovery mode, and did a wipe, and cleaned cache partition also. AND, the phone just sprung to life, the whole first time set up thing. I started filling in stuff and the phone just shut down again, and if I tried to reboot again, it doesn't get past boot logo. But if I wipe n do it, it happens but shuts down immediately Please help!!

Boot into download mode, get a stock rom from Samfirmware, flash it with Odin (How ? Thread stickied near top of Q&A).

No command error - after factory reset

OK i was having a lot of problem with my samsung s3. It was hanging a lot. The phone hangs every time. so was fed up with that a lot.
So i tried to factory reset from the reset menu. The phone switched off and after restarting it is not booting. It gives error - No command with a green adnroid laying down.
I dont know about the firmware version and modem and etc. But it was on the India Stock Rom no root.
I am able to go to the download menu only, no booting and no reovery mode..
Flash a stock firmware with Odin, then factory reset again in recovery.

stuck on twrp logo after reset

My phone is a verzon note 2 on deodox 4.3 with twrp recovery. The phone only boots to teamwin logo and flickers on and off. my computer will not recognize my phone either at this point.This is what happened. Ive been having some 4g lte loss and unstable wifi issues to i decided to do a factoty reset. when i rebooted into recovery i was stuck at the twrp logo and it would constantly bootloop the twrp logo.. I restarted my phone and did a factory reset from under the general setting. At that point it rebooted int the twrp but continued to just stay at the logo and would not go into recovery. I pulled the battery and restarted the phone but from that point on it would only boot into the twrp logo and stay there. I can get into download mode but my pc (win7) no longer recognizes the phone so i cant attempt to fix this in odin. Im not sure what to do to get this phone to work properly at this point.

My guess is that when you rooted with CASUAL, it changed the Samsung device driver on your computer and you need to reinstall the Samsung driver to get the computer to recognize the phone again in download mode.
Underneath step 7 of section 1b on Droidstyle's restore guide, he discusses issue with CASUAL replacing the Samsung driver... and he gives a link to Jeremy Loper's fix... "If odin no longer recognizes your device, most likely Casual killed the driver for odin!! follow this tutorial for restoring the driver: http://www.youtube.com/watch?v=zzghcV8HVVk"
Once the computer recognizes the phone again, you should be able to use ODIN to restore back to 4.1.2 so you can root/unlock again with CASUAL. After you get the phone restored with Odin, I would recommend booting into Stock Recovery and wiping cache/doing factory reset before running Casual again... this would enure you are starting over with a totally clean slate.
If the above doesn't work, then here's a thread where I tried to help someone else who couldn't get their computer to recognize the phone.... maybe some of those ideas will help - http://forum.xda-developers.com/showthread.php?p=55833998
Good luck!!
1 step forward two steps back. I got my pc /odin to recognizes my note 2(changed usb cords). Then tried to odin back to stock 4.1.2. At first odin kept saying (odin not responding) and would ask to close the program,after several attemps i final got it to flash the 4.1.2 file. When i flashed the file and was at the point where it reboots, it would not get past the samsung note 2 logo and continued to flicker and not boot up even when i tried to put it into download mode like it said to in this thread. http://forum.xda-developers.com/showthread.php?t=2024207. When i tried to reflash the file it failed. when i attempted again it just hangs at setupconnection. Tried again and it failed. Btw thanks for the help mattnmag.
Got it working! i simply forgot to place the sch-i605 pit. into the pit section of odin when i flashed the 4.1.2 rom.
Similar problems
I was running AllianceROM 26. My phone had been spontaneously rebooting for a bit recently. Today, it started to spontaneously reboot again, but this time, it never got past the Galaxy Note 2 screen. After pulling the battery, I tried to boot into TWRP. It just hangs on the twrp boot screen for a few minutes but never goes into twrp.
I figured I would try taking it back to stock. So, I used ODIN to try and put 4.1.2 on it and a new PIT file. That appeared to work fine. I got no errors in ODIN. However, I still cannot get this thing to get past these boot screens, either the Galaxy Note 2 one or TWRP when I try that there. I have tried this twice now, once with re-partition checked and another time with re-partition unchecked (saw conflicting instructions on that so I figured I would try it both ways). I still am not getting past the boot screen.
Any help or ideas are appreciated as right now, my phone appears to be bricked and I am out of ideas.
so what was the solution to the teamwin flashing on and off after a factory reset? this is certainly not a solution, having to reflash the phone...

[Q] Help! S3 mini hangs, infinite reboots, no recovery

Hi!
My samsung s3 mini just freezed the other day while I was texting. I lost my patience after 5-10 minutes and pulled the battery. It started up again, and now it just reboots, runs about 1-2 minutes, reboot, runs another minute and continues so on... I was running full stock. No root what so ever.
If it's to any use, I can't delete anything on the phone when it's running. Photos, apps etc... It disappears at first but when the phone has rebooted again all the things that I deleted is still there.
Now here's the thing. It won't go into recovery mode. When I try, it freezes at the first screen, no yellow triangle showing.
Here's what i've tried:
- Flashing another kernel with odin. Tried to flash CWM, according to odin it's succesful, but it's the same thing as before when I try to boot in recovery mode. I also tried flashing a stock kernel but with same results.
- Flashing a stock ROM with odin. Same thing. Odin says it's succesful, but it's the same ROM as before the flash.
- Factory reset in settings on the phone (yeah, I tried doing a factory reset on those 2 minutes lol). When I click the delete button nothing happens.
I've searched the entire internet lol... No one seems to have the same problem as me.
What can I do?
Big thanks in advance.. :laugh:
