My Samsung Galaxy Mini won't turn on, when I press the start up button a message comes up on the screen i.e.( lcd-backlight-ctrl start
determine-lcd-type,lcd type:61bc11) but nothing else happens. When I press Vol down+Home+Power, phone boot on with a lot of texts,
and start normally. I can't get recovery mode or downloading mode for odin use. Can anyone help me please? I'm newbie. Thanx

Same problem right here. Any idea?

What have you done before facing this issue?
Sent from my GT-S5570 using xda premium

In my case, volum up button doesn't work, and phone doesn't enter in downlaod model, just in some emergency mode arm9... something like that. I try to update software, i think because it's some software problem. After that, everything ok (start downlaod mode with kies, and update with odin). Odin show pass(isn't first phone that I update with odin, but everything before was ok). When phone start, show this .... and i don't know what should I do. Any help, any idea?

Be careful and press only vol down and not both volup and down...try.

Before, I update with odin: Galaxy S, Galaxy gio(2x), Galaxy ace(3x), another galaxy mini, with odin.

Weird it is then, cuz i know holding volup+down+home+power will get u to emergency download mode...whatever that is.

It's possible.The person who gave it to me to make them update said the volume up button does not work very well. Be a reason? Phone also have another problem, battery drain, in 5 minutes, battery goes from 70% to 20%. Wipe battery stats in CWM should resolve this? 100% probably no, but something?

Im having the same problem, I get "lcd_backlight_ctrl start" when im trying to turn my phone on, can only go to Emergency download mode
I have firmware from http://forum.xda-developers.com/showthread.php?t=1551586 and i get this error after i tryed to go to recovery mode (Clockwork recovery not flashed)
EDIT: Got into normal download mode, reflashed roms, now its working fine. Apperiantly theres a problem with my "Volume up" button.

For future
This combination which u have triggered is: Volume up + menu + power or just Volume Up + power

you just have to put off your battery from your phone and then put it in to the phone, finally you have to press vol down+power button until the phone logo is shown up

How To Root Android 5.0 With TWRP Recovery Or CFAUTO-ROOT!

Note: This trips knox as always.
This has been tested and working fine on my T800 and other devices that people confired. I'm not responsible for any bricks btw. Twrp Method:
VOLUME UP = RIGHT BUTTON OF VOLUME. VOLUME DOWN=LEFT VOLUME BUTTON
1. Download the twrp.tar on your pc and supersu.zip on your device. Also, download odin on your pc
2. Open odin on your pc.
3. Put device into download mode by turning off the tab s first. Then hold power,home, volume down button all at the same time till download mode comes up.
4. Hit volume up to continue
5. Connect tablet to pc.
6. Hit the ap or PDA button in odin.
7. Select the recovery tar.
8. Untick auto reboot in odin
9. Hit start
10. Now force reboot by holding power,home, volume up and volume down buttons at the same time till it reboots.
11. Power device off again.
12. Reboot into recovery by holding power,home, volume up buttons all at the same time till twrp pops up.
13. Hit install button in twrp.
14. Select the supersu zip you downloaded.
15. Swipe to install and reboot.
Done!
Download links:
supersu zip(download on device): http://download.chainfire.eu/supersu
Twrp T80X(download on pc): http://dl.twrp.me/chagallwifi/
Twrp T70X (download on pc) http://dl.twrp.me/klimtwifi/
CFAUTO-ROOT Method(Confirmed working on Lollipop) Incase twrp fails...

Follow these instructions to the letter. Do not touch any buttons or checkboxes that are not listed below to touch!
- Download and unzip the CF-Auto-Root-....zip file (see posts below this one)
- If you end up with a recovery.img and cache.img file, you've extracted twice. You need to end up with a .tar.md5 file - don't extract that one
- (USB) Disconnect your phone from your computer
- Start Odin3-vX.X.exe
- Click the PDA (AP in odin v3.x) button, and select CF-Auto-Root-....tar.md5
- Put your phone in download mode (turn off phone, then hold VolDown+Home+Power to boot - if it asks you to press a button to continue, press the listed button, or run adb reboot download command)
- (USB) Connect the phone to your computer
- Make sure Repartition is NOT checked
- Click the Start button
- Wait for Android to boot
- Done (if it took you more than 30 seconds, you need practise!)
NOTE: Sometimes the device does *not* boot into recovery mode and root your device. Just do the entire procedure again if this happens. If it still will not install root and such, make sure that in Odin "Auto Reboot" is not checked. Then after flashing, manually shutdown your device and boot with VolUp+Home+Power button to boot into recovery manually. This will start the install process.
New to Samsung? Unfamiliar with Odin? Think all the above is a hassle? Get used to it. It's very simple, and us Samsung folk use Odin (or Mobile ODIN ) for everything! It's so very very convenient once you get used to it. Notice the 30 second comment above? For experienced users, the entire process indeed takes only 30 seconds!
Flashing with Odin
1. Put your phone into download mode. To do this turn the phone off and then press volume down+home button+power button at the same time. You will then get a warning saying press up to continue and down to cancel, press volume up and you are now in download mode
2. Start Odin
3.At this point please make sure that ONLY TWO OPTIONS TICKED are "Auto Reboot" and "F.Reset Time" (otherwise you could end up with a very expensive paperweight)

4. If there was only one tar file when you extracted the firmware put it in the PDA section.This just means this file contains the PDA+PHONE+CSC all in one firmware
If there are three files they should have one of PDA/PHONE/CSC in their names look for this and put them in the corresponding section.
5. Plug your device into the computer, wait for the drivers to install and then wait for the ID:COM section to turn blue.
6.ONCE AGAIN CHECK YOU HAVE NOT TICKED RE-PARTITION OR PUT IN A PIT FILE
7.Press start and the flash will begin, once this has started do not remove the usb cable or turn of your computer or the device the phone will reboot once the flash has finished.

Hello,
I've tried several times and it doesn't work, TWRP not showing, only stock recovery
I've flashed with Modified CF-AutoRoot and it's working.
L.E. : None is working. I get SuperSU update binary Installation failed.
L.E. 2 : I've wiped data/cache a few times and re-downloading the TWRP tar file, and now it is working. Thank you!

Update: Added CFauto-root method just in case

Works perfect for me with twrp-method. Lollipop is blazing fast. No lag at all.

So.. Is this for previously unrooted devices? If so, does it trip KNOX?

This is for people who want root on lollipop since flashing the new firmware wipes it. And yes it does trip knox. I'll add a note that it does in the first post

Added recovery links for T700/T705. Forgot to do so

Bump. Incase any T705 users needs it ☺

I'm sure one of the things new users will find confusing is the precise button combination needed to trigger each of the different boot states, download, recovery and normal modes. Pressing volume up will lead to a boot state different from pressing volume down, since the two buttons are externally the same (the volume rocker). Maybe you can highlight or emphasize the UP or DOWN since it's easy to overlook.

Maybe a little confusing for t700/705 users as their volume button is the opposite I believe.
I think your instructions were clear enough. The user of the device should at least know which is up and which is down tbh. No need to spoon feed imo.

Actually, if you install TWRP from odin, you don't even need to download the supersu separately. First, download twrp package for your device. Install it with odin. From my experience, you don't need to disable the auto-reboot option in odin this time (but you need that when you're installing full ROMs and want to keep the custom firmware).
Shutdown.
Boot into recovery, by pressing volume up, power, and home buttons.
Confirm that TWRP recovery is installed.
Now reboot. At the moment you try to reboot, the custom recovery will offer you to install SuperSU. Go ahead and accept it.
Now reboot, go into google play and update your SuperSU.
One nice side effect of installing TWRP this way is that you may want to keep TWRP without having root. TWRT is useful as a recovery for backups etc, but there are some apps, like AT&T Uverse, that will actually break if you have root.

I flashed my Lenovo A7000a (MT6752) to update to android 6.0 (it was rooted)with the "format all then download" option on SP tool. Now when i try to switch it on it shows a blank screen and dies. When connect my phone (power button down ofcourse) to pc with the SPTool download button activated, I am able to flash my phone again, but result is the same. The autorun for LenovoSuite even pops up when I connect the phone to PC. I am thinking that I may have flashed the wrong/bad ROM to my phone, will update again
Update: Flashed with "download only" option with an older ROM, phone is able to boot, but with the same blank screen, and I can press the power button to turn the screen off, or on. Not able to boot into recovery mode, meta mode, or whatever anything, just a white blank screen.

your initial issue was that you DIDINT format data when you first flashed twrp. please read dr.ketans guide in the guides and discussion thread.
when the phone reboots by holding vold down and power, very very quickly swap to the DL button combo(vol down + bixby) and plug cable. reflash twrp 3.2.0.0 and follow the instructions. ( when odin fisnishes flashing twrp in the AP slot, DONT let phone boot to home screen or at all. immediately hold vol up +bixby +pwr to enter twrp recovery. then swipe to allow modification and go directly to wipe menu and format data. type yes when asked. go to reboot menu and choose reboot to recovery and flash

jd14771 said:
follow these steps, you must be fast and diligent with the button combinations:
-first, plug phone into computer
-Second, HOLD POWER + VOLUME DOWN until device restarts, as SOON as the screen goes black you must let go of all buttons and immediately hold VOLUME DOWN + BIXBY
-you should be in download mode.
the phone has to be OFF and plugged into a computer BEFORE you hold VOLUME DOWN + BiXBY in order to enter download mode. You can not trigger this while the phone is on.

Samsung Galaxy M31s stuck on Download mode boot loop

Hey, everybody!!
I seem to have incurred an issue while I was manually trying to install an OTA update in my Samsung Galaxy M31s through the ODIN Mode with the help of this video...
After I successfully followed all the steps in the video... after the last step when ODIN showed in pass in bright green colour. So it did in mine.
My phone rebooted as predicted in that video, only to get stuck in the endless Download/Odin Mode. Now, whatever I do, including pressing the Volume Down + Side key (for 7 seconds) while it's connected/disconnected to/from the PC... it keeps booting into the Download mode... I also tried pressing the Volume Up + Volume Down + Side Key(altogether), yet it keeps booting into the Download mode...!! Can you please suggest me a fix for this ASAP, 'cause I'm scared AF for my phone right now, and the data it stores. PLEASE HELP!! And...
Thank You(in advance)!!​

It's some vbmeta issue...
Try going back to download mode or recovery and flashing null vbmeta.img... and then your patched firmware again...
-> For booting again to recovery mode:
▪︎ Press vol_up + power key [for few secs](it will force restart your phone)
▪︎ As soon as black screen appears, press vol_up & power key and connect cable it will take you to recovery
mode.
-> For booting again to download mode:
▪︎ Press vol_down + power key [for few secs](it will force restart your phone)
▪︎ As soon as black screen appears, press vol_up & down and connect cable it will take you to download mode(Note: Even after having experience sometimes this trick take me 2-3 tries, so don't get dishearted easily).

Correction...
That was vol_up(not down) for recovery mode (typo).

Hey, for some reason neither ODIN nor my computer can to recognize that my phone is linked to it. Even after installing the Samsung Mobile Drivers for Windows, I gave it a shot. However, I was out of luck there as well, and my phone continued to refuse to appear in ODIN or be recognized by my PC.
I also tried using your approach to start it in recovery mode, but it didn't work either; all it did was boot into Download mode after displaying the Samsung logo. I believe it may be that my PC isn't picking up my device by itself.
How should I proceed?

Although my device does seem to show up when I connect it to another phone (same model in this case), but yet when I open in the settings, the USB transfer is controlled by my device which is currently stuck in Download mode, and I can't seem to switch it back to the functional device.
And one more thing, I know that my PC's USB is working since, before the flash ODIN, as well as my PC were able to detect my device... but after the Download mode boot loop, none of the attempts seem to be identifying my PHONE...
Thanks @killerboychetan your help is much appreciated!!

Ok, got you...
See bro, as like windows have secure boot Android also has AVB(Android Verified Boot). While flashing anything other than pure stock stuff, you need to disable AVB(if what you are flashing has not something to disable it) & to disable AVB, you have to flash null vbmeta.img to set AVB to zero.
[ Note: vbmeta is some sort of file which has verify boot metadata]
So, basically you are exactly not in flashing page of Download mode but rather in AVB warning page, to to get out of AVB warning you have to let phone battery die... [if it ain't]
& as far as i know restart drains battery a lot faster(i even tied my friend phone's vol_down & power button with something, when he get into a similar situation)
And when the battery completely died, pressed vol_up & down key together & connected the cable & then it went to real Download mode than i flashed stock on that case but in your case flashing null vbmeta will work.

Ok, got you...
See bro, as like windows have secure boot Android also has AVB(Android Verified Boot). While flashing anything other than pure stock stuff, you need to disable AVB(if what you are flashing has not something to disable it) & to disable AVB, you have to flash null vbmeta.img to set AVB to zero.
[ Note: vbmeta is some sort of file which has verify boot metadata]

Thank you so much for your response... Just two questions here:
If the battery is dead and then I connect it to the PC... wouldn't the phone just die out again... in between the flash since, my PC won't be able to charge the phone with the necessary power... so what do I do then?
And, would flashing this null vbmeta.img file factory reset my phone...!!? I mean yeah I get it that, it's better having the phone bricked... but I was just asking if it does/doesn't factory reset my phone... Honestly no problem, either ways!!
Thank You, so so so so so so so much... my friend!!
I owe you bro...!! FR... Thank You so much!!

Try going back to download mode or recovery and flashing null vbmeta.img... and then your patched firmware again...

• After phone battery get dead, charge it till 3%(not more than that as if you get stuck, drain again will problematic)
Also, download mode don't require much battery & phone charge even in download mode.
• No way man... never... it's just a 4kb file carrying secure boot info. (It's just for some security purpose, which i feel some useless)

Oh! Sry, i forgot to tell you, how to flash vbmeta with ODIN.
So, first zip/archive vbmeta.img to .tar format by using 7zip or something...
Then flash that vbmeta.tar in AP in odin(Also, whenever you flash something with odin always remember to Turn-off auto-restart.

This issue has been already fixed...
It's requested to MODs, pls close this thread.
~Thanks
