[Q] Android 2.2 build i9000XXJPH messed up my T-mobile Vibrant

So I installed this (Android 2.2 build i9000XXJPH) on my Tmobile Vibrant and it worked beautifully, but then I went to root my device through "one-click" and when it got to the part in recovery mode, i tried pressing the power button to apply the update but nothing happened and now I'm stuck in recovery mode all the time, as soon as I plug the phone in to charge, or plug it in the computer via usb, or push the power button, the damn thing goes into recovery mode and stays there. I can use the volume buttons to navigate up and down through the options and if I hold the power botton down long enough the phone will turn off and back on again. But if I press the power button once (as in select an option) it doesn't do anything. I tried every single option out there to get into download mode with the battery out and usb in and volume buttons then put bat in....etc nothing works. I need to get into download mode
anyone?................

Try holding volume -+ then plug in the usb at the same time this should go into download mode.
P.S. dont touch the power button for nothing.

Try these steps:
1. Take out your battery
2. Hold vol up and vol down, continue to hold
3. Insert USB while still holding down the vol buttons
That should get you into download mode (it did for me)

thanks but I already tried that, doesn't work still goes into recovery mode

Does adb work in recovery?

nope it says device not connected

Try the same procedure with the USB cable plugged in. I go into recovery if the cable is unplugged and I go into download mode if the cable is attached. Buttons are always the same. Vol +/- then power until I see the screen show something. Then release power.

Well my friend, u flashing the i9000 rom to ur fone is the problem. They button set up is different they have a big menu button in the middle and we dont. That y u cant move it at all.

make sure your phone can get into download mode before flashing a i9000 rom. If your phone is able to get into download mode before flashing a i9000 rom then it's general impossible to brick your phone by flashing a i9000 rom. After flashed to a i9000 rom, to get to download mode, you hold "volume down" + "soft home key" + "power button" for 3 seconds. If "volume down" don't work, try holding "volume up".
I have done it many times with i9000 roms...the "soft home key" is the touch home icon on the bottom of our Vibrant.

The phone works fine but the volume buttons are flipped, when u press up it goes down and when u press down it goes up, so I know thats not the right one.. anyway i got those firmwares from here "http://www.samfirmware.com/WEBPROTECT-i9000.htm" btw u need to make an account to be able to see them. so my question is, can anyone tell me where to get the original stock firmware to flash with odin? oh and I did try Kies from samsung but the phone will not connect with that for some reason.. anyway any help is very much appreciate it

I honestly searched for it, and did find few posts but everytime I flashed the phone, it just didn't feel like the right one, so thats why I asked for help here.
Thanks for the link though, much appreciated.

same issue
So i am having the same issue...gonna try to get it into download mode and go back to stock. You (original poster) said you had the Android 2.2 build i9000XXJPH working in your device? I did'nt get that far, that is what has me stuck in this recovery limbo...how did you originally get it to work? And also assuming I work for T-MO, assume that 2.2 is coming out NO time soon!! This kind of is a bummer, I love the vibrant but I think I need to go back to a true android, I can't keep feeling left behind because Samsung cares more about friggin avatar then updating their phones.

Flash the froyo that dont brick your phone (search the forum), and after that flash the stock vibrant.

If you flash a ROM not meant for your phone I'm surprised you made it this far.
~SB

toast
Yea i was suprised I made it this far too....BUT now my vibrant is toast!! I had it back to stock, woke up this morning and accidentally accepted the J16 OTA from TMO, and now my phone is done done done....I cant get it to do anything, no lights, camera or action. So having no way to get back to download mode I think Im screwed. This was a problem from the gate, cause Samsung gave me the phone from a learning seminar and the 1st J16 MR soft bricked me. So at this point I have searced every forum I can find and I think Im screwed. NOw if I could only get ahold of my Samsung rep to see if they replace it for me....IF anyone has any strokes of genius to maybe help me out please....

[Q] Galaxy Note 4 stuck in boot loop with No Command window no acces to recovery mode

I've encountered the following problem with my Galaxy Note 4: I just bought it online from a guy who turned out to be a fraud and I was not able to find or contact him again via the internet market place. So that was really stupid of me...and expensive...and I regret it very much and with hind site I should have picked up the signs but...o well you got the picture...I got ripped.
Anyways after careful inspection it turned out to be a real genuine Note 4 N910F with 64 Gb but with a korean or chinese or something recovery mode (I saw it once when I got home), an imei not to be found on any stolen phone list and working correctly with an european rom that includes English and Dutch at that point.
That's when I decided to factory reset it and then I got into trouble again: For some reason it got stuck in a boot loop with just a No Command message. Normally you can reach the recovery mode by pressing Volume Up +Home +Power but now nothing happens. It's not a real brick but with just the No Command message and no access to the recovery mode I don't know how to fix this.
Can anyone help me with a clue on how to get out of a No Command loop without recovery mode? Or how to get into recovery mode if start with Key Up etc does not work? Or any other clue that could help me?
Thanks in advance!
Kind regards,
Rene (aka the guy who got ripped off but hopes to save the phone)

Can you get into download mode?

Thanks dr.mOx for responding!
I tried both volume up+home+power to get into recovery mode and also volume down+home+power to get into download mode but in both cases the device starts and shows me the android robot on it's back with a red warning triangle containing an exclamation mark and below the robot the message "No command." . The screen blinks every two or three seconds. The power button is not shutting the phone down in this state. I have to remove the battery to retry.

Battey out. Then in. Go to download mode. Flash stock rom with odin

Hi Ozzyblack. The thing is that, if I'm correct, when I press volume down+home+power to get into download mode I expect some sort of menu to appear asking to go into download mode or not. Am I correct? I saw same sceendump about that. And now I keep getting the No Command window. Do you think I miss something here? I do press volume down first, then home (keeping volume down pressed), and them the power button (keeping all buttons pressed). After a few seconds the display turns a bit more grey for a sec and then the android robot appears. But no message of sorts about getting into download mode.

Hi reborn67.
**Only if you have a galaxy note 4 N910F model**
If you can get into download mode your safe, and you can reflash an offical ROM, there is no menu system in Download mode so don't worry.
Don't stay in download mode forever or a long time, i.e. power off and wait till you have the ROM and Odin before you go into download mode as it sometimes times out even though it still shows in download mode.
Go to here http://samsung-updates.com/details/37086/Galaxy_Note_4_Snapdragon/SM-N910F/DBT/N910FXXU1ANK4.html download the ROM, and then download Odin here https://mega.co.nz/#!UdRRyCAT!H4FyVxYynNWvXqRNmnpMGQRCP-dG3uykgP2pT4rh8Ek
These are the instructions from sammobile on how to flash ROm with Odin.Instructions
1-Extract (unzip) the firmware file
2-Download Odin v3.09
3-Extract Odin zip-file
4-Open Odin v3.09 (make sure the extracted rom file "N910FXXU1ANK4_N910FOXA1ANK4_N910FXXU1ANK4_HOME.tar.md5" is in the same folder as Odin before opening up Odin.
5-Reboot phone in Download Mode (press and hold Home + Power + Volume Down buttons)
6-Connect phone and wait until you get a blue/orange sign in Odin (above text top left ID:COM)
7-Add the firmware file to AP / PDA
IMPORTANT** Make sure re-partition is NOT ticked
Click the start button, sit back and wait a few minutes
I always do a hard reset after flashing new ROM's (settings, backup and reset, factory data reset)
I have a network locked UK N910F on EE and use this German ROM with no problems, this ROM has little bloatware.

Thanks gadjet. I do have odin and a stock rom ready for use now:
1-I tested odin and the usb port plus driver setup with my 'old' galaxy s4 and within a second the ID:Com in Odin turns blue. So that seems to be working fine.
2-So now I put in the Note 4 battery and connect to usb WITHOUT ANY KEYS PRESSED...just to test! And the usb connection bleeps from windows confirm a device is connected...so far so good.
3-Last and most important step fails: Reboot phone in Download Mode (press and hold Home + Power + Volume Down buttons), the 'no command' robot is still there, and also connect phone and wait until you get a blue/orange sign in Odin (above text top left ID:COM) never happens. And also there are no windows usb connection bleeps so apparently there's a difference when I tried to select download mode.
Please know that I'm really thankful for all the great tips. But I guess I'm still missing something here.
Kind regards,
Rene

This is different
Turn your phone off or make sure it’s turned off.
Press and hold the Volume Up, Home and Power buttons simultaneously.
When the phone vibrates, release the Home and Power buttons, but keep pressing Volume Up button.

OK, corrupt boat-loader Samsung service centre repair job, or local phone repair job.
Requires boot chip to be reflashed at board level.
Sorry we couldn't get you going bud..:crying:

Thanks for trying guys!
I'll see if I can find a local phone repair store.

I used to have the same problem with my SM-P605 when I flashed some ROM in the summer, the only special thing I did was not giving up and after all I got to the Download mode. Hope it'll work for you without Service.
Good Luck

Today I went to visit an official Samsung store. They told me I bought a very good but fake Note 4 and it is not likely it can be recovered. The weight is incorrect...a bit to heavy. Also the serial numbers are unknown in the samsung database and some other details were not correct. Thanks again for trying to help me! I now officially have a really expensive brick that looks like a note 4.:crying:

same issue i am facing..i tried all..but it shows no command error and no menu shows up
ill be going to get my phone checked today..if i get any way out ill let u know

What you did later to recover ? I'm facing the same problem I've visited samsung service centre but they are unable to solve it.

Can you guys help me for my phone Samsung note 4 because its just keep repeating in a logo SAMSUNG...
I tried pressing volume down+home button+power then got "WARNING CUSTOM OS... and stuff and then I press volume high+home button+power then I got the logo SAMSUNG that keeps on repeating. Please help me what to do

Recovery Is Not Seandroid Enforcing

I tried to root my phone S7 Edge 6.1.1 just a moment ago using ODIN and CF Auto Root. I got the PASSES! sign in ODIN but upon phone rebooting I am stuck on the Samsung S7 Edge logo screen with text in red 'Recovery Is Not Seandroid Enforcing" up the top.
At this time I am unable to turn my phone off, when I do it just turns back on and goes to the same screen. I can't get into download or recovery mode either.
Any help on how to fix would by greatly appreciated.
Thanks in advance.

Also thought I should add, my phone doesn't get registered when I connect it to my PC either, it wont show up in ODIN so I am unable to flash a stock recovery at this time.

It's trying to boot into recovery.
When you say you rooted with CF Auto Root, what did you do precisely? And did you follow Chainfire's specific instructions regarding the lack of screen output during the process?

Thanks for the reply.
I used CF-Auto-Root-zerolte-zeroltexx-smg925f.tar to root.
The steps I used was to simply put my phone into download mode and use ODIN to flash the file mentioned above. That is as far as I got unfortunately. I did this once before, a few month back when I first got the phone with no issues. I remember having to install TWRP but I couldn't remember if I did that pre-root or post-root. But I think that is where I went wrong.
Now I am unable to do anything with my phone. I can't turn it off, get into download or recovery mode. When I hold down VOL UP+POWER+HOME it just resets the phone back to the samsung logo screen.
Any ideas on what I could do?

You used the CF Auto Root file for an S6 Edge.

OH GOD. You're right. I just realized that. I was supposed to have them saved into their own folders but I guess I saved that one too the wrong folder.
So what does that mean for the life of my phone then? Is it toast or is it recoverable somehow?

What is your model? Is it the SM-G935F? If so, first things first, download the correct CF Auto Root file for your device (here) and try again. Press VOL DOWN+POWER+HOME and it should reboot into Download Mode. Then try to flash the correct file in Odin again.
These phones are very difficult to hard brick, especially with something like CF Auto Root so you should be ok.

Yes, it is a SM-G935F. Unfortunately I am unable to reboot the phone into Download Mode. When pressing VOL DOWN+POWER+HOME it just takes me straight back to the Samsung logo where it says "Recovery Is Not Seandroid Enforcing". I'm hoping that once the battery drains completely I will be able to boot into Download Mode again.

Try simply resetting it instead. Press volume down and the power key (don't press home) for around 7-10 seconds. Once it starts to reset, remove your fingers from the buttons very briefly then press volume down, home and power to enter download mode.

That hasn't worked either unfortunately.

I just found this thread from a guy having a similar problem. He just had to wait for his phone's battery to drain completely and then he was able to enter download mode again.

You shouldn't have to though. If you can get the phone to reset at all (even if it's to make another attempt to go into recovery) then providing you time it right, you should be able to get into download mode. Did keeping your fingers on just the volume down and power buttons do anything? Keep them on continuously for up to 20 seconds and see what happens. Did you say pressing vol up & home & power made it reset and try to again get into recovery? What happens if, as soon as the screen indicated it's resetting, you remove your fingers and quickly press vol down & home & power instead?
Anyway, even if you have to wait until the phone dies, getting into download will be possible eventually. Then worst case scenario would be you having to reflash stock back. Or, as would be my preference, flash TWRP then flash a custom rom zip like Superman.
Just to confirm, I take it you selected OEM Unlock in dev options?

I have never had any trouble getting into recovery or download before so I know the method. But just the properly clarify for you I will explain some of the combination I have tried without success. Bare in mind the phone is constantly turned on and idles on the Samsung logo.
I have tried:
Hold VOL DOWN+POWER+HOME, the phone resets and goes back to the logo.
Hold VOL DOWN+POWER, same as above.
Hold VOL UP+POWER+HOME, nothing happens at all.
Hold VOL UP+POWER, same as above.
Hold VOL DOWN+POWER+HOME, release and repress all on black screen, just goes back to logo.
Hold VOL DOWN+POWER, release and hold VOL DOWN+POWER+HOME on black screen, just goes back to logo.
and numerous other things like random combination to try and enter Download or Recovery mode, which have all failed.
Right now it's just stuck on the Samsung logo and staying there, taking forever to drain battery. I work in the morning so hopefully it is dead by then and I can get into Download mode.
Have already started download stock firmware in hopes that I will be able to flash it after.
Thanks a bunch for your help. If you think of anything else I might be able to try let me know!

Oh wow. 100+ attempts and I followed your last post about holding for up to 20 seconds. I was waiting ~5 seconds and releasing thinking that it hadn't worked.
Finally go into Download mode and will flash stock firmware and let you know how I go.
Thanks again! I owe you a cold one.
EDIT: Was no need to flash stock firmware. Just flashed the proper version of CF Auto Root and it worked. Again, thank you so much!

Fantastic. Hope you get it sorted.
On a side note, you have probably already tripped knox and you will have lost you OS data and possibly even what you have stored on internal storage. If so, I suggest you install TWRP, format data (you will lose everything with this but it removed encryption) and install a custom rom like Superman 1.9 from your external SD. It's better than plain stock and comes pre-rooted with plenty of other mods.

I can't get it to work? What keys did you held down?

I was not very clever and cofirmed the question "fix the root problem" I don't remember exactly the words. After that root was gone.
I've flashed the stock Fw G935FXXU1APD1_G935FDRE1APC3_DRE but I still have the message "recovery is not seandroid enforcing" after trying to root with CF auto root.
AP:G935FXXU1APD1

Is there any way to get root again
Any help on how to fix would by greatly appreciated.
Thanks in advance.

Simply hold down Home + Power + Volume Down for 10-15 seconds - don't release when the phone initially reboots and gives the same error, keep them held down and download mode will appear. I have to hold for 11 seconds, a strangely unrounded number.

Hello Guys I have this Same issue Yesterday....... This happens when you flash outdated CF Autoroot. CF Autoroot Updated on 25/08/2016... Download it...
Fix for Stuck in Logo Screen
Just Click and Hold ...... Vol Down + Menu + Power Keys ...... DO NOT RELEASE. IT Will Restart. DONT release. It will restart again and you will be download mode.

i found this during the rooting process. its a bit different to older samsungs on the s7 / s7edge. YOU HAVE TO KEEP HOLD OF VOL DOWN + HOME + POWER until it enters download mode, which can be 20-25 seconds

After android update, S7 Edge freezes on boot and won't turn off anymore!!!!!

Hello Everyone,
I never rooted my phone, my Edge S7 after last android update freezes on Samsung S7 Edge, "Powered by Android" logo.. and the worst, I can't turn it off!! Yes, is true, I have to wait the battery to drain totally to see the phone off.
What I have tried:
Tried key combination: VOL DOWN + Power, it restarts, but again I enter in this boot screen logo freezed.
Tried key combination: VOL UP + DOWN + Power to boot off, nothing happens.
Tried key combination: VOL UP + Home + Power to enter in Android recovery mode, nothing helps (I tried in every state possible).
Download mode combination works, so:
Kies using the restore option (with IMEI).. keep the same.
Used Odin to flash last firmware from samsung update site, nothing.
All my tried it keep stay showing Samsung S7 Edge, "Powered by Android" logo without any clue what's going on behind.
My version is from German, please guys, any idea what I can do in this case? Return it back is a very hard option as I'm far far away from where I bought it.
Thanks in advance

Seems like an hardware issue with the internal motherboard. If you did not do any flashing/update before this happened most likely will be hardware failure and you may need to visit the Service Center.
Another possibility is that you may have flashed the file for the wrong model

Did you try getting to recovery mode while pressing VOL UP+ HOME + POWER? Sounds like you missed the home button in that step.

Thats strange. I had a scare similar to that the other day. I thought I would never get my phone to work but what I did was this:
VOL DOWN + POWER Until it reboots.
As soon as the screen goes dark, really fast, hold the VOL DOWN, HOME and POWER buttons until you see download mode. After that, I flashed the original firmware for my device through odin and it booted normally.
The other option is to force reboot it with VOL DOWN + POWER and then VOL UP + HOME + POWER to go into recovery and shut it down from there, and THEN go into Download Mode, but it seems not even that is working for you. If your warranty is still active, I'd recommend going to where you bought it from to get it replaced or fixed. If they say they cant do anything, you can always contact Samsung to file a claim directly with them for service.

Hi there, I have same issue, have s7 edge sm-G935F stuck at logo. I downloaded 2 different firmware from z3x box(shell) and if keep failing when using odin (latest) and also getting error when using Samsung tool.Also I can't get in the phone menu to check the baseband..can only get model from download model.any advice to this?

A20e stuck in download mode

Hi,
I have a new a20e (a202f) out of the box.
I followed another guide to root and install twrp which turns out was wrong. I unlocked the bootloader just fine.
I have no backup, no personal boot.img or anything.
Essentially I am stuck in download mode and restarting takes me straight back to download mode.
Recovery: Error validating footer.
SW REV. CHECK FAIL (BOOTLOADER) DEVICE"
Cheers guys

What guide did you follow? You have to download your stock fw from sites like sammobile then from there you can have the boot.img and etc. Have you tried flashing stock fw using odin?
Note: Usually you flash vbmeta for footer error when you flash twrp.

It was a guide on 'unofficialtwrp.com' - I can't link things here yet.
I have since tar'ed an unpatched twrp (TWRP-3.3.1.0_A20_by_Agrim720.img) + vbmeta.img + boot.img (from https://forum.xda-developers.com/galaxy-a20/help/boo-img-a205fxxu2asfb-t4008739), then I flashed through AP on Odin and now I think it boots past the download mode but instead it now has fuzzy dark red screen with nothing legible.
Oh bugger, I've been a class A plum.
Can I get out of this horrible mess?

I have since tar'ed an unpatched twrp (TWRP-3.3.1.0_A20_by_Agrim720.img) + vbmeta.img + boot.img (from https://forum.xda-developers.com/galaxy-a20/help/boo-img-a205fxxu2asfb-t4008739), then I flashed through AP on Odin and now I think it boots past the download mode but instead it now has fuzzy dark red screen with nothing legible.
Oh bugger, I've been a class A plum.
Can I get out of this horrible mess?

Well you have to use your own boot.img from your fw, not all of use the same fw that's why, some are still on u2, u3 and u4. Maybe the boot.img you got isnt the same as your fw.
Well you can start from scratch and reflash your stock fw in odin.

Try holding volume - and power and your phone will turn off, as soon as it turns off press volume + & - and plug your usb cable that is connected to a computer.

No luck with that. It displays the message about running custom os etc and to press power to continue. So I press it and it boots to the messed up red/pink/black display.

Do you mean like the one attached? If yes you havent booted to download mode.
Try booting to recovery by holding volume + and power while you turn on the phone.
There is a option there to boot to download mode.

Yes that screen. I've tried your suggestion with volume + but that also ends up with messed up screen

Yes so currently I'm unable to get to recovery (not sure it even flashed properly), unable to get to download mode, or to get the device recognised in odin.
I'm unable to power off. The screen is blank and when I press power it flickers shortly with some black/white/red pink colours around the edges, but the screen quickly turns blank.
From this position I can only restart by holding volume - and power.
This boots to the samsung logo and then the 'bootloader unlocked' warning. No amount of button configs have proved successful so far, and then I end up back at the blank screen.
I'm happy to start from scratch. I have downloaded the stock firmware but I'm simply unable to proceed.
Aslo the device is not recognised in windows at any point.
Thanks guys

Are you sure you pressed and hold volume +&- and plugging cable before the samsung logo pops up? You have to do it quickly right after the device turns off. You shoudn't see the bootloader warning if you done this quickly and correctly.

Hello -
Please trust me when I tell you that it can be fixed. I had the EXACT same problem and drove me crazy for 24 hours. You can deffinetly fix your phone once you get to download mode.
I had the same issue where I could not turn the phone OFF it just looped back and I pushed buttons for hours to no avail... Then some one told me it WILL WORK, it is just the timing of
the button pushing, AND the USB cable plug in. Sure enough he was right. It took me alot of tries and I even took my phone apart and un plugged the battery so I could controll the power
ON / OFF better and time the button's easier. Here is what I did ...
unplug battery so phone was 100% OFF.
Plug in battery ( phone is still OFF )
Hold Vol - then Hold Power and Vol -
As soon as the power started IMEDITALY PLUG IN USB ( have USB READY to be plugged in FAST )
DONT let go of buttons ... screen will flash quickly and then Imediatly let go of power keep holding Vol -
IF you timed this right, IT WILL proced to download mode. If not, then start over again from power OFF ( step 01 )
It took me 3 tries to get it ( after 50+ tries before ) lol
Now I am not sure about the battery unplugging ... maybe you dont need to, but it mad it work for me as I could control the power ON part of this now.
Getting to your battery is not very hard and there is a you tube video on how to do it... if you need help just PM ME.
Good luck friend.

When this happened to me all I did was hold volume up and volume down. Kept cord connected to computer. Connected to device during the bootloop and boom within seconds I was in download mode. It catches it once screen goes off in between the bootloop.

Thanks you guys. In the end the battery died and then I could power up whilst holding vol+, straight to recovery and then I could flash stock rom.
Much appreciation for your help guys, it got me out of a pinch - it is my mother-in-law's new phone!

Hi,
I have a new a20e (a202f) out of the box.
I followed another guide to root and install twrp which turns out was wrong. I unlocked the bootloader just fine.
I have no backup, no personal boot.img or anything.
Essentially I am stuck in download mode and restarting takes me straight back to download mode.
Recovery: Error validating footer.
SW REV. CHECK FAIL (BOOTLOADER) DEVICE"
Cheers guys
