Hold volume up, volume down, and power on A20U05U1 US Version - custom ROM menu - Samsung Galaxy A20 Questions & Answers

Not sure if anybody else with more knowledge has tried this, but just out of curiosity, I held down volume up, volume down, and power on when booting my A20U05U1 (US Version) and it brought up a warning screen that said something like:
"Warning, installing a custom ROM, blah, blah, blah. Do you wish to continue?"
Pushed the power button (I think it was) and it switched to a screen that said:
Now downloading (I wasn't connected to anything) do not power off (and some other text) and below it:
(press volume down and power for 7 seconds to reboot)."
I of course immediately freaked out and did the V down and power.
See the pictures
So, if anybody is feeling adventurous... I'd take the risk, it's only a $200 phone, but I just don't have the knowledge base - I can follow the step-by-step guides with the best of them, but that's about as far as I go.
Wondering if this opens a door for us or is just another tease????
After spending some time with Google, I see this is download mode so probably old news. And looking at the picture I took, I see the one status is "locked" so it's likely nothing.
Sorry!

Unfortunately the US version can't be unlocked.
All the other A20s use this method to download from a PC using Odin as described here.

@no99sqrd
Can you run;
Code:
adb getprop | grep oem
and post the results for me? I would love to get the OEM Unlock option working on this device if it's possible.

Behold 2

I was wondering if anyone is working on a way to fully root the Behold 2. I tried the temporary root tutorial but seeing how fastboot cannot be accessed I was curious if there has been progress made or is it totally unrootable
Eric
Yeah i'm working on it without a behold 2 at the monent
I have 2 or 3 ideas which i'm sure will work. I'll have more when i finally get rid of my galaxy and get a behold 2
I will keep my fingers crossed on you getting a Behold 2. I was going to take my Behold 2 back to T-Mobile and go back to the MyTouch 3G but I cant see getting rid of a device when there is soooo much potential for it. Plus having the AMOLED screen and the 5MP camera helps too.
Eric
don't forget 320mb ram!! even more than any other HTC phone right now.
The Behold II is nice, I have one, anything I can do to help let me know, I am very eager to root this thing and get rid of touch wiz.
u can install open home which should do it for now.
Thats already done, but there is still the taint of touchwiz.. wonderful phone, horrible UI.
Yeah I had Open Home on it as well but earlier today I purchased GDE from the market and am really digging this home replacement.
Eric
Found this by accident, cant figure out how to do it again. was trying to get into recovery mode.
Awesome. So it can be accessed somehow. that is VERY good news
Eric
Interesting!
You can flash the recovery through Odin too, but its restored on the next boot.
Fastboot mode
Ok so I have been able to reproduce it now, this is how I am getting into fastboot, have your usb cable plugged into your computer then plug it into the phone, very quickly press vol down + send + power. thats it, the part i was missing was the usb cable timing, it appears to be required, this is of course from a powered off state.
GREAT I just tried this and it WORKS yessssss.... someone wanna try rc29
I keep trying to get this, and all it does is bring me to recovery whether I hold or briefly press volume down, send, and power.... any suggestions?
It's powered off, plug in usb cable, quickly press buttons, and I get recovery... no fastboot for me
EDIT:GOT IT!!!!! Seems after trying in order volume down, send, power I wasn't able to get it, however, I just tried, send, volume down, power in that order and it worked!
no no no .,.,..
power off wait 5 sec's
plug usb in and immediately press volume down, send, and power
I think the reboot issue is caused by a scan in an init script or something like that..
To solve this issue I would have to look deeper into it, a quicker way would be to find someone who knows java.
He could write an app which starts itself on boot_completed and executes the root command.
I was looking at exactly that Getting there...
Getting there.
hehe, cant wait.
man i sure hope someone figure out how soon, i love this phone
This guy found a work around for the samsung moment ,,, which suffers the same reboot issue...

New method for Vibrant Recovery mode

Hey!
First I have to say Thank You for all the contributions you have made to the forums. My girlfriend and I both just bought Vibrants 2 weeks ago, and being the techy I am, have been reading all sorts of stuff in the forums. I actually have been visiting the XDA forums since last year when I got my MyTouch 3G. I haven't posted anything, because usually by the time I have a question, I come to the forums and find an answers then in the moments of happiness, fail to say thank you to the community.
So it's time to start contributing.
I've been reading about the numerous processes on how to get into the Recovery mode for the Vibrant, and the possibility of the Hardware Locked phones.
After exhausting all options, I decided to call Tmo and see if they could help. Well long story short I went back to the store, and they gave me a new procedure (at least one that I have not seen on the forums so far) to test out. And it works!!
I've been doing it over and over for the last hour and each time I've been able to get into recovery mode.
Here it is...
Start with the phone ON and NOT plugged into the computer OR wall for charging.
1. Power down the phone as usual. Wait until the "Goodbye" disappears and then wait a few more seconds. DO NOT TOUCH ANYTHING DURING THIS TIME.
2. Press and hold Vol+,Vol-, & Power.
3. Wait for the Vibrant logo to appear.
4. Wait for the Vibrant logo to disappear.
5. Wait for the Vibrant logo to appear again.
6. Release ONLY Vol+, & Power, and continue to hold Vol -.
RECOVERY MODE!!!
Most of the process I have seen tell you to hold down and keep holding both Vol+ and Vol-, but I could never get it to work.
Please let me know if this works for you.
And I also want to say that I"m sorry if I have posted this in the wrong spot, or this procedure is some where that I haven't read yet. But I finally found something that worked and wanted to share.
Good Luck!
Reg.
Didn't work for me. Lemme try again.
EDIT: Works! Awesome. I never heard of this way to enter recovery, but it's good. +1.
But I don't have a hardware locked Vibrant so maybe it's different for me.
I get in every time with every VIbrant i have used.
Power off phone
Power on holding power, vol up and vol down
When the Samsung logo appears let go of power and continue to hold vol up and vol down.
Works everytime for me..... *Shrugs*

Granted. But this procedure does not work for all vibrants.
I think OP is saying this method would work with hardware locked phones, where the normal recovery mode method doesn't work.
I'm trying this on my hardware locked phone right now. Third time's a charm?
*Edit* Nothing, 10 times unlucky.
Tested on Hardware Locked Vibrant, doesn't work.
The Vibrant screen disappearing and coming back is nothing but the phone powering on and off, because you are holding down the power key.
I had already tried this in the T-Mo store (the CSR walked usthrough it on the phone - we tried it about 50 times, mind you), and I just tried it again about 30 seconds ago.
I wish these threads would stop.
If you get locked out of your phone, brick it, whatever, and it's hardware locked.
Just get a damn replacement.
You're not going to get into recovery or download mode on it.
Seriously.
You won't.
I've been waiting for a replacement for like 5 days now, and I've been basically living on this forum. I've tried everything there is to try. Making new threads is not going to do anything but frustrate more people, because none of these magic methods will allow them to get into recovery/download via the hardware keys on a boot-up.
Edit: Exception is if you root and can disable the lockout via adb, of course. Most consumers who find this site via Google will already have this issue, and will likely not be rooted with USB debugging enabled. The phone makes it way too easy to disabled USB debugging that even if it came enabled by default, most people who charge with a laptop will see the notification and click it ignorantly (ignorant of the benefits it can provide in the event of a catastrophe like mine).

I actually saw someone in a reply mention something like this, but nothing ever came of it. They were looking for boot.bin and another file, which I can't remember at the moment.
Do you have any other info regarding a method to do this?

I think this is the latest fad for trolls. Post some crazy key combination that is supposed to work for hardware locked phones, claim it "WORKS 100%"! Bottom line, don't get your hopes up, it didn't work for me either.

it will only help you look like a troll, because the hardware locked phones domt evem attempt to read those key states on boot. The only way to fix it is with a firmware update.
there is no magic method to gettimg these phones in dlm/recovery.
so stop making threads about it.
to the person above: if u have usb debugging on u can use adb to disengage the lock, but in that case why even have a lock. the main issue is the android bug not allowimg legit owners to unlock their owm phones using their own google cred en tials.
if tjat didn't exist we wouldnt have to worry about these patt er n lockout threads.
a legit owner who gets the phone replaced would never sell the locked phone, unless they wanma pay t-mo or asurion an extra $300+ USD

I'm new you the Vibrant and not very techy at all, so what is the purpose of the recovery mode, other than the obvious term?

Obviously you don't, or else you would not have clicked the clearly marked title hoping for something. I mean...really?

Well why did you click on the post, read it, then try the stated method? Did you have any hope? Or, were you looking forward to being frustrated? Really man? Really?
Bottom line: I don't think the OP promised any "magic" fix or claimed it would certainly help all Vibrant users. I took it as he/she was hopeful to be able to contribute something to the community believing it might help. I wish the posts where people are complaining about other people's posts (hardware locks, Froyo, etc.) would stop. Stop clicking.

Cannot get into download mode after official ICS update

First off, I hope I posted this in the right forum. If not, then I offer my apologies.
Secondly, my problem is pretty much described in the title to this thread. I was going to wait until after the official ICS update before rooting my tab (sounds a bit silly, I know). Now, I have the official update installed and I was trying to follow directions to root the tab - all of which want the tab to be in download mode. The problem is that when I power down the tab and then hold the volume down + power button, I get the white "Samsung Galaxy Tab 10.1" startup screen. If I continue to hold down the two buttons, then the tab simply reboots, never getting past the startup screen I just described (it will continue to reboot every few seconds for as long as I hold the two buttons down). If I release the two buttons right after that startup screen (as I've seen a few tutorials recommend), then the tab boots up normally.
Any thoughts on either an alternate method to get the tab into download mode, or on what I can do to correct this so I can get into download mode???
I will throw you a bone here friend...my policy is, everybody gets one. lol!
In reading this, I am scared for you if you are thinking about doing any flashing this early.
You are not following the procedure to get into download mode properly. Hold Power and Vol Down ONLY until you see the Galaxy Tab logo. Then release the Power button while continuing to hold Volume down until you see the two icons for recovery and download mode.
I very adamantly suggest you spend at least a week reading the basic How To's on this site or you risk wrecking your device. Not trying to be rude or condesending but your post really does expose your lack of research good luck!
I've flashed an HTC Hero, 2 Evo 4G's, 3 Samsung Epics and a Moment, so I'm not exactly new to flashing/rooting/rom-ing. This is, however, the first tablet I've tried to flash.
I appreciate you boning me, djmatt604 ( ). That was exactly what I needed and I am now in download mode. Thank you, thank you, thank you!
Hold on the power button just until the samsung screens appear, if you hold the power button for 10s it will force shutdown your device.

Haha! Just paying it forward bud I got much of the same when I got started! Your account details definitely aren't indicative of a seasoned flasher lol...Glad you're in good shape!
Actualy you dont have to hold powerbutton the whole time.
Just turn off. Press power (not holding) and you can directly after that press and hold vol down till the download/recover chooser appears.

That's because I can usually figure things out with the immense help of google and the myriad of forums available. For some reason, I just didn't grasp that you had to hold the volume down button and release the power button. I'm rooted and happy now.
Thanks to all that replied, I appreciate you all!!!!
Right on bro, enjoy your tab!

Cant enter download mode - Please help

Guys,
so i've done some searching to no avail so i'm desperately asking for some help so i can fix my pregnant's wife cell phone (she really needs it)
I rooted her LG G2 (ATT) some time back. I never installed any recovery or custom ROM. She received an update software notification and I told her not to accept. Well coincidently later on in the day her phone stopped working (she states she did press software update button).
He phone is bricked and boots only to the LG G2 logo and she gets a boot certification error and phone turns off (but i think screen still off).
Attempting to do a hard reset did not work, i got the same LG screen with same error
I decided to flash back to stock, i understand the process and have done this before on my LG G3.
Only problem is when i try to go into download mode and plug USB into phone I get pop up messages on my laptop asking me to format local disk h: I notice that every time I attempt to go into download mode and plug the phone in, i get a bunch of local drives that pop up. I tried formatting out of desperation, but it told me disk was protected.
No idea wha'ts going on. Anyone know why i get a bunch of local drive disks instead of my phone going into download mode when i plug into my laptop?
I greatly appreciate the help, i've been at this for 3 hrs and i'm frustrated.
I think my problem may be that the phone is not truly "OFF" and i don't know how to turn this completely off since there's no battery to pull. I'm not even sure if this is the problem, but just an idea.
I tried letting the phone die completely. I thought i'd be able to let it die, charge it a bit, then hold volume up and plug it into computer to get into download mode. I thought i was a genius, until the phone died and as soon as i plugged it into charge it automatically went into bootloop again.
I think the problem is that i can't turn off the phone to get into download mode.
Any ideas?
bumping in this in hopes of some help. Still can't get this thing to go into download mode.

When I get a boot certification error my phone is always in a state when I can never truly turn it off.
When I hold the POWER button it turns OFF, then immediately turns ON again when I release the POWER button.
My solution? Hold the POWER button down for about 30 seconds.
My screen turns off at around the 10 second mark and after a while I let go of the POWER button and my phone stays OFF.
It's probably best to do this in a dark room so you can tell if the screen is really OFF.
If you're having trouble truly turning your device OFF, try THIS tutorial. It involves removing the rear case of your G2 and disconnecting your Battery.
Okay now.. assuming you got your phone to turn OFF.. continue reading..
Make sure you have the LG Drivers installed on your PC. You can download them HERE.
After installing those Drivers, download and install the Universal ADB Drivers from HERE.
Now after doing the above, try Download Mode again. Hold Volume UP and plug your phone into your PC via USB (keep holding Volume UP until you see "Download Mode").
Success? If so.. visit THIS tutorial and do the "TOT Method".
No Success? Post back and let me know :good:. You may need to follow THIS tutorial as a final solution.

I am trying this now. I was uncertain of my wife's phones fate and gave up on it so this morning i had to go to ATT and get her a new phone. She travels alot and is pregnant so she needs a phone and i had no choice but to upgrade her to the S6(she was long over due)
I am still going to try this method so i can restore and sell on ebay. Hope it works!
You're welcome.

Stock Mi A1 locked on Fastboot screen

Ok, here's as much info as I can give as my phone is locked up:
Stock Mi A1 with 1st Oreo update: December patch level
I have not tried to load anything custom on it, nor have I even loaded the apps to do so.
I took my phone out of my pocket and it is locked on on a screen that says Fastboot.
Power button does not work. Long press power button does not work. Power+UP volume button does not work. Power+UP+DOWN volume buttons do not work.
Plugging the phone into the computer via USB port does nothing.
The battery is non-removable, so I can't pull it to reset.
I am at a complete loss as to what happened, why it happened, and how to resolve it. The phone was working fine this morning. I took it out of my pocket to use it and then discovered the issue. I live in Thailand, and there are no local service centers for Xiaomi, so hopefully someone will have an idea of how to fix the issue.
Any help, ideas or suggestions would be MOST appreciated!
Regards,
KB
UPDATE: I tried to restart the phone via the power button while it was plugged into the computer via USB. Holding the power button down for 10 seconds (guesstimate) did force a restart. This was NOT the case when not plugged in. In any event, if anyone has an idea of what happened and why, I would really like to know! I am wondering if there was some sort of long press key combo or something that happened while it was in my pocket.
Sorry for replying to my own post, but I am totally confused by this issue. I did a lot of searching and reading on Fastboot, and they ALL said that to get there, you had to enable Developer Tools on your phone, download a program for your computer, and then connect the phone via USB.
Here's the thing: I have a photo of the screen, so this is not some hallucination!
1) I DID NOT have Developer Tools enabled on the device. (I do now as I enabled it to see if it was already enabled...it wasn't)
2) I DID NOT download and install an ADB program for the computer.
3) I DID NOT (before the issue) connect the phone to the computer via USB.
So my question is how the h*ll did I get into Fastboot?????
This is really concerning as maybe Xiaomi has an issue similar to the root issue One Plus had and I happened to pocket dial the right combo???? In any event, it does not give me a warm fuzzy about what is going on behind the scenes here!
Any thoughts or info appreciated.

To get phone into fastboot mode you have to hold power off + volume down button. Might have happened in tight pocket.

Thanks mysiak...in all my reading, nowhere was that mentioned! And yeah, it was in a pocket pressed up against a seat, so could easily have pocket dialed that combo.
Also, it is not easy to find the solution when it is locked there. I THOUGHT I had held the power off button long enough when trying to get out of Fastboot, but maybe missed it by a second or two. My solution was just to hold down the power button until the phone turned off. Whether that is the correct solution, I don't know as I still have not found anything about getting into and out of Fastboot without a computer.

Power+volume down button is the usual way how to get into fastboot mode. From a PC you can type "adb reboot bootloader", but many prefer just using phone buttons combo (myself including). If you want to get out of fastboot, you either hold power off button until phone vibrates shortly - this works in whatever mode, even if powered on, basically it's "emergency shutdown" as we don't have removable battery. Or if you are connected to a PC, type "fastboot reboot".
Long story short, you did it right
Btw. if you will hold power+volume up combo long enough, you'll end in stock recovery mode with "no command" on the screen. Don't panic, just hold power off button and then start phone normally
I had the same problem and plugged into the computer via USB and holding the power button down for 10 seconds did force a restart. and the phone is OK since then!!! Thank you you saved my time!!!
Thank you.
Picked up my Mi A1 this morning and it had the beautiful FASTBOOT icon on the screen. The phone has been lying on my desk for several weeks without a SIM. When I could not clear the FASTBOOT message I Googled for a solution and this thread was the result. I just wanted to record my grateful thanks. I plugged the phone into a computer USB socket and held the power button until the error message disappeared, as recommended by KB_Thailand..
XDA doing what it aims to do.:good:
It is always nice to find solutions instead of even more questions. Glad that it helped!
After the initial glitches, the A1 has been pretty dang dependable.
I still am using my A1. The A2 and A3 (someone needs to be fired over that monstrosity) left me flat. I am hoping against hope that the A4 will be 'the one', otherwise I am going to have to look for something other than Xiaomi.
