Hi everyone,
My xperia sp is stuck at sony's logo and wont start up after trying to install trinity vengeance custom rom.
Model: C3506
Build: 12.0.A.1.284
Locked bootloader
I used Doomlord method to root the phone.(worked)
Installed CMW(worked)
Went In recovery mode,full wipe,wipe dalvik cache and rebooted the phone.
After that I dropped trinity vengeance zip file into x sp sd using my computer.
Went back to recovery,installed the zip file,went through the installer,everything worked fine,rebooted ...
then I was stuck at sony logo :crying:
Trying to use flashboot or sony companion pc to repair my phone but I need to turn it off but it wont
even force turn off wont work(opening the back and pressing the thing) it just reboot everytime after 5 seconds
When I connect it to my pc it just charges and boot when it got enough juice
Any idea on how to fix my phone?
Thanx

you have to hold the button (inside cover one) for about 3 to 4 seconds to turn it off. it always works for me.

Turn the phone off on the back, Set up flash tool first, select correct ftf file then select flash, at this point flashtool should show picture of how phone and green arrow. Plug usb into phone, then hold volume down and plug usb into pc. Flashtool should then flash ftf. Hope this helps.

Ok fixed thanx,just had to reboot with back button,then hold volume down and when the green light appears I release the volume down button
and it flash the trt file in it

[Q] Dead xperia v

Hi all.. So i have one xperia v. First, the phone freeze randomly, screen turns purple and fade into black and reboot itself. Idk why, been searching for solutions and found that it's the battery problem. And now, when i try to turn it on, it got stuck at the sony logo again and again (bootloop). Tried to enter recovery mod, failed. Tried to enter fastboot mod, failed too. Connecting to charger still the phone wont charge, bootloop. Tried to connect it to pc, it didn't detect the phone. The battery is still in good condition. Does anyone have these problems? Is my phone, dead?
Thank you for any help given :'(

You could try to enter fastboot mode after having removed the battery.
This will work, as I'm always getting rid of broken kernel builds that way.
Try to connect the phone with removed battery and power/volume up buttons pressed simultaneously.

The phone itself wont boot into fastboot or recovery :'C

When you connect the phone in fastboot, the indicator light will turn into green, the screen stays black. Nothing like that happened?

If that is the case, I think it's time you bring it to service center

[Q]

Hello.
Cant get any help anywhere, hope here someone will help me.
I have LG G2 VS980 32Gb version. I have rooted it myself, I installed on it TWRP bootloader and xdabbeb_vs980_3.1.2 ROM and everything worked perfect.
But I wanted to install CM12, when I was doing that TWRP "told" me something like "your device is not rooted, do you want to root the device" with yes button. I thought "why not?" and pushed the button.
After that phone has no reaction on any combination of buttons, but Windows 8.1 see my phone as qhsusb_bulk.
P.S. I cant get it to download mode.
can someone help me?

If you installed TWRP, then boot into it by holding pwr + vol down until lg logo shows then do it again it will then load twrp. Click yes twice to factory reset.. Its not reallly gonna do it since your rooted. The rom probably isnt enabled in settings.

pluged it with ac charger it did not charge.
pluged it in PC with Windows 8.1, sees it as qhsusb_bulk
pluged it in PC with Slax Linux 7.0.8, it did not see it.
pluged it in PC with CentOS 7, it did not see it.

So there is a unbrick utility in the verizon forums G2. If you was in twrp before and you didnt Reflash the recovery then its bootable to twrp. What happens when you turn the phone on. Vol down and pwr when turning on release the buttons and then hold those buttons again and it will load twrp. Do you see the LG Logo at all or you in fastboot mode?

You have to make sure you are using a fastboot cable
Edit: TWRP is a custom recovery not a bootloader. 39a bootstack is required lollipop for the LG G2 verizon VS980 model. Have you try flashing stock. If you bumped twrp to your device then you should be able to access it. If the device is fully dead find a fastboot cable just so it will show the LG logo and that point you can load twrp. You cant revive a dead device or can I? Lol also your selinux must be set to permissive or your device will not boot. TWRP doesnt require root to flash roms and make backups. If you have a sign of any life your device is not bricked. I have bricked many devices and i have found a way back. Just stay positive If you need more help post screenshots of your cable and use a wall charger not usb!!!!

Stuck on bootloop

Hi,
I have got a huge problem: got bootloop after flashing Havoc OS because I forgot to instal bootloop fix. But it's not the worse. I have broken volume up button so I cant go to recovery by power+volume up, and, I dont know why, after pressing power+volume down, my phone turn off and I cant even go to fastboot.
Any ideas what can I do?

Please try to press the power button for at least 10 seconds to force reboot the phone, when the MI logo shows up, press power+volume down and enter fastboot. Then connect to computer and reboot to recovery via ADB.

I did that, but the fastbot screen doesn't show up. It was like that because I had Darkness Kernel and it show always darkness theme instead of f.e. fastbot screen. But thanks for answer @andoidZhao.
Problem already solved. Thread's dead :]

Same happened with me..... my vol down button is not working.. when press vol up + power it isn't go to twrp..... Any method to flash rom while phone switch off??

No luck with Recovery mode in SmartSwitch PC app, it says "smart switch does not support initializing, please contact service center"
Tried to flash magisk tar file via odin after enable oem unlock in developer options. However, at the end of flash device shows boot-loader locked and device always boot to screen showing " An error has occurred while update the device software. User Emergency recovery function in the smart Switch PC software"
Mode: S10 5G SM-G977B
AOSV: Android 10. DTM-G977BXXU2BSL2
Any input how to enter into download mode?

Kozmike, wait until the phone battery dies, charge to 40% and boot into download mode. Flash the original firmware for your Model.

@zeroktal, The device never boots directly into Download mode, FYI on S10-5G (SM-G977B) the download mode standard key combo(Vol-Down+Bixy+Power) is disabled and the only way to enter into download mode is to first boot into recovery mode and select menu option boot into boot-loader.

Did you wait for the battery to die? Also you CAN boot directly into download mode. I know this because, I literally just did it 10 minutes ago. This exact process, dead battery and all.

Heyya guys, I've personally could always boot directly into download mode full battery or not. Regardless if you manage to boot to download mode, flash stick non edited firmware first to see if you make progress, the bootloader being locked is a little scary but I'm 50% sure you can flash stock firmware still. Also you've stated you can get into recovery, is this stick recovery menu or twrp?. If twrp format cache, if stock have you tried a normal format?

Yes, the device will show the "Emergency recovery mode" screen only when I plugin the charger cable. and will die when unplugged the charging cable. tired different approach to enter into download mode but no luck, the device always boots to emergency recovery screen.
BTW is your device SM-G977B 5G with android-10? may be android-9 has standard key combo to get into download mode.

I had stock recovery, may I know how did you unlock the bootloader? Please explain the steps in detail.

I'm android 10-sm-g977b too. Standard button combos work for me. I unlocked my bootloader over 6 months ago, but the steps are available. The generally gist is going into developer menu, turning on OEM unlock, booting into download mode and holding a certain button to finish the process. Though im not 100 sure but it may wipe your data. Also if say you don't go download mode and unlock straight away you may need to wait a week to try agajn as the option would be greyed out

Also remember you must have your phone plugged into the computer with the computer having all the correct drivers for you to get into download mode, otherwise the button combo will do nothing and holding those buttons without the cable will just turn your device on and off as the phone thinks your just holding the power button down and that's it ?

Good job guys, i'm happy to see you guys helped each other and it was awaken from the dead! :good:

Hi XDA community.
I have the same issue as CP-93. I own a SK Telecom Galaxy S10 5G SM-G977N.
I tried yesterday to flash a custom rom, so first I flashed the TWRP recovery using Odin, then I was stuck after flashing the recovery in a bootloop with the same screen as CP-93 attached in this thread, with no access to recovery mode nor download mode, it just keeps rebooting until the battery dies I guess.
Can someone please explain to me how can I access again the download mode so I can reflash the stock rom?
Thanks in advance for the amazing support of this community.
Best regards.

I have the same problem ... how is he?
