It did not work and when i try to BOOT it normally, it is stuck on a PHONE....!....COMPUTER screen
Also TRIED:
Super One Click 2.1.1 shortfuse
RESULT:
Stays at "waiting on device"
THEN tried to install drivers and now it FREEEZES on "waiting on device"
Wow this is complicated. can anybody PLEASE tell me what i need to do to FIX this and ROOT it??
ALSO i cannot reach USB DEBUGGING because i cannot get past the PHONE.....!.....COMPUTER screen.

please guys i really need help. I've tried everything!

Sooo....you used the PDA button when you odined the file, right? If you used the phone button you probably seriously damaged your phone.
And if you want to try Odining again, just pop the battery out, and then hold the volume down button while plugging your phone into your computer. That should get you in a working download mode...

yess i used PDA. Not only that, but now i cannot get into download mode anymore,\. Whenever i plug it into the usb it just has a grey battery on the screen with the circle progress bar frozen.

So to clarify, you pulled the battery, then with one end of your USB cable plugged into the computer, held down your volume down button, then plugged in the other end of your USB cable to your phone (you should still be holding the volume down button) and after a few seconds you're still not getting into download mode?
Do you happen to have a custom recovery flashed to your phone? You can enter recovery by holding both volume buttons, then hold your power button until you see the boot logo, you can then release the power button. (continue holding both volume buttons until you enter a menu screen with a few options)

Please post your question in the q&a section and more experienced users will help you!

The only other idea I have left is to hold volume up + power button for 6 seconds and see if you can boot into download mode again with the method I mentioned before.
And based off a distant memory of being stuck at the "PHONE ! COMPUTER" screen that was still considered download mode and it connected to Odin just fine.
Otherwise since debugging is disabled adb won't work (to my knowledge) I'm out of ideas, I'd post this in the Q&A section like that guy suggested to see if they can help further.

thanks for the help, but odin doesnt seem to be recognizing the phone on the PHONE ! COMPUTER logo. If you can point me to any links to drivers that i can download and install, i'll try those out too. My last bet would be to buy 3 resistors and try to get it to download mode that way, but thats the LAST thing i'd do.
Also, when i plug it into a usb and do the normal button combo i've been doing before, it just goes to a GREY BATTERY screen and it just freezes there now.

close thread please. i have a another problem which i have put into another thread

Issue with updating to ICS (P6810)

I seem to be unable to update my 7.7 to ICS through Odin. I'm a Newbie but the guidance seems straight forward.
I downloaded the rar file, extracted the P6810OXALPL_P6810XXLPL_HOME.tar.md5 and followed the steps but nothing happens.I searched the forum but could not find an answer.
The bootscreen on my tab says:
_________________________________________________________________________
Android system recovery <3e>
Volume up/down to move highlighted:
power button to select.
reboot system now
apply update from external storage
wipe data/factory reset

_________________________________________________________________________
When I select "apply update from external storage", it just brings me to the sdcard so I'm not sure if this is the download mode that is being referred to..
Odin does see the tab and when I load the P6810XXPL file under PDA and press start, screen says:
<ID:0/005> Added!!
<OSM> Enter CS for MD5..
<OSM> Check MD5.. Do not unplug the cable..

then nothing happens until I disconnect the tab and when I reboot, it´s still HC
What am I doing wrong?

Are you using PC odin? If so you go into download mode not recovery. I did mine yesterday and you dont have to touch the devices screen, its all done on the PC

I'm using PC Odin but I'm not sure how to go into download mode; power+volume down gives me the recovery mode
What should the screens (Odin and tab) say and how long does the upgrade take?

Hold power n vol down till it come to green android with some warning, next press volume up, hook it up with yr com next. open odin
Select pda find the tar u dl tick only auto reboot and f.reset time. Next start.

Are you sure you're doing vol down (furthest away from power)? Have you tried it doing volume the other way?
Intitially you get a warning asking you to press vol up to continue or vol down to cancel, once you press vol up it will show a green android man and say downloading do not turn off target

That was the trick :silly:

no problem, glad it helped

HD audio on I9500 (or so it seems)

Hi everyone
As an owner of the i9500 I was annoyed from the really low quality of call I was having. I tried the latest modems but had no luck in enabling the HD audio as was mentioned here
Here is how I managed to improve my voice call - I have no idea if it will work for others with I9500 - but please if it does for you, do tell
1) Download the I9500 XXUBMEA modem (I9500_XXUBMEA_MODEM.rar) from here or here (source). extract the I9500_XXUBMEA_MODEM.tar.md5 from it.
2) put your S4 in ODIN mode (power off, press the volume-down + home key + power button, a warning appears, let go of the keys, press volume up)
3) start ODIN. (I used ODIN 3.07 but I assume any will work), Press the "phone" button, select the I9500_XXUBMEA_MODEM.tar.md5 file. check the auto reboot option. press start.
4) this was my ODIN log:

<OSM> All threads completed. (succeed 1 / failed 0)
5) if successful, the phone will reboot. in my case it started but the mobile network was not working anymore. no problems.
5) time for service mode. Dial *#0011#
6) press menu key, than "back".
7) You're now in debug screen. press the menu key and "back". welcome to service mode
8) press the menu key and select 8 (Which is selecting the "WB-AMR status)
9) it should say
WB-AMR SETTING: 1(ON)
GSM WB: OFF(14)
UTMS WB: ON(10)
if that is the case, congratulations you just enabled the WB-AMR (well, you didn't but the firmware you installed did).
11) get the XXUFNC1 radio (i9500_RADIO_XXUFNC1.zip) from here. if you're using a computer, copy it to the the phone
12) power off the phone. reboot into recovery (volume-up + home key + power key, let go when you see the Samsung logo). I have CWM-based recovery V6.0.3.3
13) select "install zip" and select the i9500_RADIO_XXUFNC1.zip file.
14) reboot your phone (and fix root).
15) sound quality should be better now.
It improved my call sound quality - if it worked for you please share
PS
I tried the "latest" Chinese modem (i9500_RADIO_ I9500ZCUGND1) and the sound quality was horrible... don't use it

Hi,
This problem has been driving me crazy so I'm looking for a fix too. I have been burned in the past with bricking devices so I went ahead and tested out some steps (5-10.. notice your post doesn't include "10", although it's clear enough) and with my current setup (i9500, 4.4.2, I9500XXUFNA6) I cannot perform the service menu steps.. After dialing *#0011# I see something titled Service Menu but after menu->back nothing changes and after menu->key input or menu-> select .. 8 I get a "menu not exist" message..
Is this something that will not be a problem after installing the first radio in earlier steps? Or is this something else that is locked down in my phone?
Thanks.. just being extra careful not to brick yet another device this year... And thanks for addressing the horrible in-call sound quality of the S4.. I'm sick of not being able to understand anyone.. The work around I've found is to use voip such as skype which sounds just completely amazing and clear (so I know it's not a speaker problem)...

Thanks for the tutorial. After flashing the modem via Odin I was able to access the service menu, which I couldn't do before.
My problem is that my settings show WB-AMR SETTING: 0(OFF). Is HD voice region locked? If I change my CSC will it then show as ON?
What is your CSC?

It did not work for ozcanrom 4.1

Having problems with odin and my gs8+ can someone help?

I've been a member for a long time on this forum and never had a problem rooting any of my phones with the instructions and files from here but I can't seem to be able to get my gs8 to pass odin.
I have the sm-g955u snapdragon model and followed every step correctly but when I hit start on the modded odin it just stays on initializing for a minute or so and and get a message saying attempts completed (0/1) and will keep getting the message every time I click start afterwards. Anyone know what could be happening? I've enabled usb debugging as well and tried other odins and different files but nothing seems to work. I'm desperate here and really need some help so any help would be appreciated thanks ?

Can you try copying the entire Odin log here? It might be helpful.

Root at your own risk. This is a different issue...

Found this:

I'd say just rebooting into download mode itself while connected before hitting start would work too...

Damn didn't work ?, I've been wanting to root this since I got my hands on it but no luck

I think I may have the solution. I've done some research and this might work:
1) Download a stock firmware for your S8 sm-g955u model
2) Boot into download mode by pressing (power + volume down + Bixby button), stop at the first screen when it asks for continuing and reboot by pressing volume down.
3) Quickly boot again into download mode by pressing power + volume down + Bixby. Press continue. It should work good with Odin now.
4) Install firmware with Odin

So download a different stock firmware first and load that into regular odin and do steps above before trying rooted fw with modded odin? I will try this once I get home
Also just noticed I posted this in the gs8 forum and not the gs8+ sorry lol

UPDATE: Still no luck!
If anyone here is in northern Cali in the bay area and knows how to do it and has the right files, im willing to pay to get it done for me ?

Stuck in emergency recovery mode

I left my tablet charging overnight, i wanted to install crdroid so i unlocked and went into download mode, flashed the vbmeta from twrp and got an error saying it couldn't verify it. So i flashed the stock .md5 files but mid flash it turned off, now it doesnt power on unless i put it on the charger. when its on the charger it goes on for 5 seconds then off, then on again and then off endlessly. Its a bright teal screen telling me to use the emergency recovery software on my pc. Its detected in odin for the 5 seconds that its on but i obviously cant flash anything in that time. I've left the thing on the charger for an hour now and its still looping in on off for 5 seconds each time

Does it turn off with no cable plugged in? Is this the message about only official binaries are allowed to be flashed?

it goes off when i unplug it but thats because the battery is completely dead then, once i plug it in it goes on automatically. The message i get is about a software update failure and i should use the emergency recovery software to fix it

Let the battery run out. Plug the USB cable into the PC only. Then, while holding both Vol up and down, plug the cable into the tablet. A green or teal screen should appear with the instruction to press and release the vol up to enter the download mode. You should then be able to flash via Odin.

Will this also work when I can only get into emergency recovery mode?. When it's in the emergency recovery mode it's already detected in Odin, unfortunately it shuts down after like 5 seconds because it doesn't charge in that mode

It should get you out of emergency recovery mode. Once the green/blue screen appears, just let it charge for awhile before proceeding. Give it a half hour or so before you try downloading. Even if the PC only charges at 500ma, that should still work.:fingers-crossed:

That's not the correct screen. You want the unlock/lock bootloader screen. Read the instructions on how to unlock the bootloader, starting with the tablet off.

This is the output im getting in odin whenever i try to flash any file (twrp, vbmeta from twrp site, stock firmware which i used before)

@lewmur the screen it is looping on is one all over you tube that says "An error has occurred while updating the device software. Use the Emergency recovery function in the Smart Switch PC software."
Problem is Smart Switch doesn't recognize it and no longer provides initialization tab. Also can't run old version without update which removes initialization. I've encountered same issue now in new S5e. While switching from LOS 17 to Luis' ROM I got weird boot screen like half download mode overlay on untrusted device boot splash. You can see in the one with mixed look that it said oem lock on then when I booted to download mode it was off. It would not boot that way so started flashing stock and about half way thru with odin it failed. From there it is as described, on for 2 seconds off for 5 seconds connected to PC. 5 seconds on and 5 off when connected to charger so guessing data+ data- is cycling something but it will not go to download mode. It goes to selection screen for bootloader, custom or vol- to cancel but restarts loop from there. Do you know of any reset requirement from that state, like possibly disconnect battery? Reconnecting battery used to solve a lot of issues and seems like it was part of most flashing instructions at one time. With newer device I don't know and didn't really want to open this one to find out if it is known to absolutely not be a possibility. Any thought on getting it be still long enough to flash ?

Maybe this will save someone's time and money.
The following story about recovering Samsung Galaxy Tab s5e.
I needed to downgrade Android version on my Galaxy Tab s5e from Android 10 to 9. I got image from the sammobile and tried to flash the tablet using Odin3 app on Windows. During the process I lost connection with my tablet and it booted with the error on the display "An error has occurred while updating the device software. Use the Emergency recovery function in the Smart Switch PC software.". In 3-5 seconds it rebooted and showed the same message. Over and over again.
Smart Switch app wasn't able to detect the tablet. I was able to switch to download mode but tablet was continuing to reboot every 3-5 seconds. So had no chance to flash the image again.
I assumed that battery level is low and tried to charge it completely enough. But that didn't work when I tried to charge with original adapter and USB type-A cable.
At this moment I was thinking that I need to take battery out and somehow charge it as my tablet doesn't want to do it by itself.
But I got better idea! I used USB type-c to USB type-c cable and connected my tablet to MacBook. So it got more power this time but it continued to reboot. I tried to the following and it was successful:
1. Unplug USB, power off the tablet.
2. Press and hold volume (+) and volume (-)
3. Connect the tablet and macbook using USB type-c to USB type-c cable.
4. Once the tablet displays the warning page ("A custom OS can cause critical problems....") , release buttons. No reboots this time!
5. I realized that it is charging now and decided to wait for an hour. That's what it!
6. I repeated flashing the image from the Odin3 app and this time it was successful
So this story has HAPPY END. Hopefully this will be helpful for somebody!
P.s. connecting the tablet to the macbook via USB type-C was the key here because the tablet was charging only on the warning page. You can start that page only when the tablet is connected to any PC but not to the power adapter.

Hi, thanks for the hint with the battery, had the same issue that it was shutting down when connected to PC after 5 seconds. Your MacBook brought me to the idea to use the same method on a USB stndard charger. So pluging in the charger while holding the Vol+ and Vol- brought me to attached screen, 5 min ago, hope it's charging now.

I needed to downgrade Android version on my Galaxy Tab s5e from Android 10 to 9. I got image from the sammobile and tried to flash the tablet using Odin3 app on Windows. During the process I lost connection with my tablet and it booted with the error on the display "An error has occurred while updating the device software. Use the Emergency recovery function in the Smart Switch PC software.". In 3-5 seconds it rebooted and showed the same message. Over and over again.
Smart Switch app wasn't able to detect the tablet. I was able to switch to download mode but tablet was continuing to reboot every 3-5 seconds. So had no chance to flash the image again.
I assumed that battery level is low and tried to charge it completely enough. But that didn't work when I tried to charge with original adapter and USB type-A cable.
At this moment I was thinking that I need to take battery out and somehow charge it as my tablet doesn't want to do it by itself.
But I got better idea! I used USB type-c to USB type-c cable and connected my tablet to MacBook. So it got more power this time but it continued to reboot. I tried to the following and it was successful:
1. Unplug USB, power off the tablet.
2. Press and hold volume (+) and volume (-)
3. Connect the tablet and macbook using USB type-c to USB type-c cable.
4. Once the tablet displays the warning page ("A custom OS can cause critical problems....") , release buttons. No reboots this time!
5. I realized that it is charging now and decided to wait for an hour. That's what it!
6. I repeated flashing the image from the Odin3 app and this time it was successful
So this story has HAPPY END. Hopefully this will be helpful for somebody!
P.s. connecting the tablet to the macbook via USB type-C was the key here because the tablet was charging only on the warning page. You can start that page only when the tablet is connected to any PC but not to the power adapter.

I don't have a macbook to try so i did it with charger
If i plug it in pc, got bootloop in confirmation screen, enter download mode, imei screen.
So i just plug it in charger, press Vol Up + Vol Down + Plug cable to charger (leave it in confirmation screen don't press Vol Up or Down).
After an hours i take it out and plug it in pc, press Vol Up to enter Download mode and voila it didn't reboot so i just flash it with Odin.
Flash won't succeed first time, i did it again and it worked
* After flash battery level is 0% through i charge it an hours so maybe its the battery problem

Step 1: HOLD volume up+down
Step 2: Plug in the cable of laptop
Step 3: When you see the download/error screen I CHANGED quickly the USB-power form laptop to socket.
Step 4: let it charge for a while and flash again.
Without you, I would never came to the idea.
