[Q] Phone will not boot, nor enter recovery mode HELP!

Was attempting to switch back to stock messaging app, and was using some old rom (mint jelly) with Titanium backup/rooted. I made the following changes :
unfreeze messaging app
restart bluetooth pairings
uninstall beauty face
uninstall best face
and then restarted my phone, and will not come back on? What the hell?
Will not enter recovery, at all. Just stays frozen on SAMSUNG. Not amused, please help if you can

Are you sure you are pressing the correct buttons? Volume UP + Power, when the device vibrates release the Power button and when 'Recovery Booting...' blue text appears release Volume UP button.
If you still can't enter the recovery mode there is only one option left: flash stock firmware with Odin!

however there doesnt look like much i can do with recovery mode. the only backup is a year old and might as well be reflashing. is there some way to get into safe mode and maybe undo the changes i made in TitBackup?

To start Safe Mode you have to Power on the device with the Volume DOWN button pressed, until it boots up

I have the same problem, no download mode on my G2 (European version, stock kitkat without root, bought it a week ago).
Just to be safe, the way I tried to launch it into download mode was:
1. Powering off the device.
2. Holding the volume up button.
3. Plugging in the USB cable (while still holding the volume up button)
The LG logo shows up for a while, after which the charging animation shows ups...

Your phone must be turned off
So, press power button and select “power off”.
Then, press the volume up button on your LG G2.
While you are holding the volume up button, plug in your phone’s USB cable.
Keep pressing the Volume up button until the download mode is being displayed.
that is the known method for G2 unless you flashed a custom boot-loader or changed the keys to enter download mode or recovery etc .... now try to enter a hard reset mode but don't apply it or all your data will be gone i say again don't approve it it is power+Vol down
if it works i think the keys combination are still in default then try to enter download mode again
if it didn't work return the mobile to be fixed or changed

Thanks for your reply!
The method you described is the same as the one I used, unfortunately it doesn't seem to work. I can't seem to get it to boot into recovery either...
I believe this reddit post describes my problem:
https://www.reddit.com/r/lgg2/comments/2n4gqa/unrooted_lg_g2_on_stock_android_442_kitkat_will/
The OP's conclusion is:
So I rooted and installed AutoRec and that got me Download Mode. Afterwards I used LG Flash Tool to flash the stock KDZ file onto my device to unroot it and to see if Download Mode is still enabled which it was not.
I believe this is LG's way of preventing users from upgrading to unofficial/unreleased firmware.

I managed to fix the issue by performing an emergency recovery using LG software. It must have been caused by one of the OTA updates.

Zuk Z1 Soft Brick

Dear XDA friends,
i always hoped not to be one of those guys, who f****d up their phones to the point of no return. I really screwed up this time. Well, here I'am writing you about my screw up.
I unlocked, rooted, flashed and repaired all kinds of android phones in the past years, never without problems, but I could always fix it somehow. Not so much this time.
Now I'm stuck at Bootscreen with the Zuk logo. I even have problems pinging the phone via ADB.
Sorry for my noobish question guys. Any help would be much appreciated.

I got this translated from a chinese website:
For fastboot mode:
The phone turned off; keep the connection turned off the data cable to the computer, press: [volume down key] [Power Key] waiting to enter the fastboot mode.
For recovery:
Turn off the device
Press and hold Power key
When vibrates Volume UP key + Volume Down key about 10 seconds
Release all key when Android logo appear then you will see Android System Recovery
Use Volume key to select Menu
Use Power key to Confirm
Can you enter any of these 2 modes?

The bootloop is just showing the ''ZUK logo'' in the middle of screen and "'powered by Android logo'' below,and the phone vibrates everytime it flashes these logos. I tried QFIL but it can only detects the unit on the first boot or first flash that is 2 secs. only from the time i press the power button, and then it disconnects and not detect the unit again. Does anyone know where can i find the scatter file , MTK ROM for zuk z1, i would like to try the SP flasher tool. Or if anyone have any idea how to solve this issue on lenovo zuk z1,pls. help.tnx

Can y get to fastboot ?

im facing the same problem after i had the stupid idea to lock the bootloader again, before that i flashed the phone successfully with the cm mod recovery and cm 13.
Has anyone found a solution to this ? or do i have to send it back ?
What i did exactly :
I locked the bootloader again and just to test it i tried flashing the recovery again , ofcourse it didn't work which was what i wanted.
Afterwards i rebootet the bootloader with sudo fastboot -i 0x2b4c reboot
now im stuck in a bootloop that i cant even stop , in other words i cant turn my phone off nor can i access the recovery or fastboot
Im feeling so stupid that i locked it again .... i will try to get into recovery after my phone ran out of battery but so far it looks quite bad...does anyone know if i will get a replacement even though it was my fault ? ( i don't need to say that it was my fault ..and the bootloader is now locked again )
UPDATE::
I found a promising thread about this problem, i will report back here if i was successful.

Please help , same problem
I am facing same issue too from 2 days. I didnt even try to flash custom roms or play with boot loader or recovery or anything. All of a sudden my phone entered boot loop. After two three bootloops phone is entering "12 apps optimized of 230 apps" mode, completing optimizing all apps and then failing to start apps, entering boot loop again.
Effort made so far to fix -
1) Went to recovery and cleared cache - didnt work
2) Went to recovery and did factory reset - factory reset did happen but boot loop didnt stop, I realized that factory reset happened because now its saying optimizing 120 apps instead of my 230 apps during the bootloop.
3) Went to recovery, Entered fast boot mode but not able to connect to PC. Fastboot devices is not showing anything. I made sure proper driver is installed after researching on XDA.
4) Went to recovery, Tried "Install update". Didnt install anything but browsed through folder structure and realized my data is intact
It will be great if someone can help me atleast recover my data before I handover phone to service center for fixing boot loop issue.

Same problem

Then u will be getting recovery Twrp mode .. then connect it to pc and u will see internal srorage in pc...now u have to copy any rom to the phone and install it via Twrp ... Thats all

Sorry For Re-posting Here. This is Solution
Why this is happening ?
Due to Dirty Flash from Zui or from COS/CMOD but suddenly Bootloader gets locked
May be Due to Some Custom Rom which only works with Old Bootloader ( And you are on latest 2.5 Zui QPST Flash)
Reasons are many. I also did same mistake. I flashed ZUI 2.5 using QPST then unlock bootloader using official site installed twrp after wiping cache system and data , Installed Lineage 0S JAN Build then without rebooting installed Lineage Nightly build (Latest) with Gapps After rebooting Phone goes into Restart endless loop on ZUK Logo. Blink and Vibrate .. After 1hr I figured it out but its 5am So slept.
HOW TO FIX ENDLESS REBOOT ON ZUK Logo ?
-> Identity vibrate patterns (Press Power Key I count 6- 7 Vibration pattern ) After long Vibrate immediately remove finger from power key.
->Once its Done (Phone completely off)
Download QPST and Official COS QPST from this Link https://goo.gl/InWQji OR https://goo.gl/iqrnlI (I am personally Very Thankful to D tech Terminal for posting Wonderful video on Youtube https://www.youtube.com/watch?v=4Dl6JkAVpuM
<- please install all drivers and software.->) @ankurpandeyvns Thanks bro.
Main Task is here and Lots of Patience is required and You also need to be very Blazing fast to achieve this.
-Once you download and install Qpst open Qfil
-Now press Volume Up only and connect USB (Just press POWER KEY only for 1 sec It will vibrate and connect)
-Without waiting hit Download button.
-Voila It will start flashing your phone again and Hence Your phone is now Revive..
-Once Revive You can use it to again flash custom Rom or stick to stock Rom if you want.
Keep Flashing !!!
Patience is Key here. And Don't lose hope.
:good:
EDITED:
While connecting to pc and by pressing Volume key you also need to press Power key for 1 sec or 2 sec until it gets detected. Thanks addicted777 (for tip)

[HELP NEEDED] Dead S10+ (SM-G975F)

Hey guys, I have a little problem and could need some Help fixing my S10+ (G975F)
What did I do:
- Flashed latest TWRP from TWRP.me + vbmeta
What happened:
- My S10 was stuck in a endless bootloop at the S10 logo, didn't boot to download mode or TWRP and my PC didn't recognize it.
My problem now:
I let the phone in that bootloop over night to let the battery discharge. Next day when it was powered of I tried entering download mode by pressing volume down + bixby and connecting the cable to my pc but the screen was just staying black, after releasing the volume down and bixby key but keeping the cable connected it started with the bootloop again, so right now there i'm out of ideas, I just can't enter the download mode or TWRP.
Any help would be really appreciated.
Best regards, Jan

Did you tried to enter recovery?
And BTW samsung download mode is super strong almost impossible to brick you aren't trying key combination correctly to enter download mode or recovery.
When phone is restarting to enter download mode
Just
Hold bixby, volume down and while holding these, put the usb-c cable in the s10+ when connected to the PC.

If I press bixby and volume down while being connected to PC I just get a blackscreen

What happened when it went to black screen instead of download mode? I mean what its shows in pc?specifically in odin? While on black screen try tu press volume up and to proceed download mode even though there is black screen if then it shows in odin then you can flash stock.
Did you unlock boot loader before flashing twrp? Did you?

any update on that?

Boot Looped

Hello! Here is my story:
I had a rooted stock os where i just changed the boot anim and everything was fine. I rebooted my device yesterday , the boot anim was fine etc. until today. When i rebooted my phone today , it booted into download mode with no reason. I didnt do any crap on it and it was fine until today. When i was in download mode i remembered i had a custom rom on my sd card so i wanted to flash twrp. I flashed it without factory reset and it didnt work. Now im stuck in a boot loop and i tried entering recovery but doesnt work.
Ok so i saw you can enter download mode with some key combo but u need the home button which this phone doesnt have (on screen controls).
Is there a way i can go in download mode and flash stock firmware with odin or unbrick the phone?

Enter Download Mode : Turn Power Off. Press and hold Volume Up key + Power Key, When Samsung Logo appears release Power Key only, keep pressing Volume Up key until Android Recovery Mode Appears.

I managed to find this method a long time ago so its fixed. Thanks for responding doe.
