Download Modes - eXpo GW820, GW825 IQ ROM Development

User Jayant was nice enough to provide us with some info bound to be useful once we can get some custom roms made for the eXpo and IQ
just re-posting this here in the new forum
Emergency Download Mode:
1. Turn the handset off.
2. Remove USB cable if you have it attached.
3. Slide out the QWERTY keyboard.
4. Press 'SPACE' key on the phone. Keep it pressed.
5. Insert the MicroUSB cable into the device. Keep the 'SPACE' key pressed.
6. 'Emergency Download' logo is displayed on the screen.
Normal Download Mode:
1. Turn the handset off.
2. Remove USB cable if you have it attached.
3. Slide out the QWERTY keyboard.
4. Press 'ENTER' key on the phone. Keep it pressed.
5. Insert the MicroUSB cable into the device. Keep the 'ENTER' key pressed.
6. LG logo comes up followed by the Windows Mobile boot logo. Continue to keep the 'ENTER' key pressed.
7. 'Normal Download' logo is displayed on the screen.

What are the differences between these two modes?

your guess as good as mine

Emergency Download mode will flash the phone completely. Normal mode will backup the NVRAM before the flash, then reflash, reboot, wait for the phone to come back up (it will come back up into normal mode), and then it will restore the NVRAM.

GUIDE: What to do in the event of "soft bricking" your tablet...

If you have flashed a rom and your tablet "soft bricks", i.e. it gets stuck at the Samsung splash screen or boot loops Recovery there is an easy way to recover without having to reflash the original firmware in ODIN (assuming you were smart and made a NANDROID backup before flashing your rom).
TURNING THE DARNED THING OFF:
Here's the problem. If you are at the Samsung splash screen or boot looping Recovery, you cannot turn your tablet off by just pressing the power button and you can't pull the battery. This prevents you from getting back into Recovery and restoring your NANDROID backup. So here is what you do:
1) Plug your tablet into your computer (this is important!).
2) Hold down the home, volume down and power buttons until you boot into download mode. Once you are prompted, push the volume up button to enter download mode completely.
3) Now, once in download mode, hold down the power and volume down buttons (not the home button this time) until you screen goes blank (your tablet MUST be plugged into your computer for this to work!). Release the buttons and you will see the battery symbol on your screen. Your tablet is now off - thank god.
4) To enter Recovery mode, hold the home, volume up and power buttons down until Recovery loads.
5) Restore your NANDROID backup.
Disaster averted.

Only works if the tablet is off. The key part of this little tutorial is just turning the tablet off when you are stuck in a loop. Once you are off you're golden.
I panicked yesterday because i can't exit download mode with a simple hold of the power key,

Hope this helped.
Thanks.
Lots of new roms. Make sure you check those firmware numbers before flashing folks!
When I was stuck on the Samsung logo for 20 minutes after installing this (beta version) rom a week or so back I did this:
1. Held down the Home, Power, Volume up and down buttons for about 10 seconds, not sure if you need all of them held down, but it seems it force restarts the tablet.
2. After the screen went black I immediately held down the Home, Power, and Volume down buttons to enter into download mode.
3. Flashed the latest XAR stock rom from SamMobile.
If anyone is testing a new kernel keep an eye on those temps. An app called CPUTemp has excellent monitoring. You want to be staying under 100c even when benchmarking.
Almost there but
I did everything you said but when i press the recovery combo nothing happens.It is as if there is no recovery!!!
Help plz.I am furstrated and angry!!!

Ok that all worked fine, but now that I got it turned off I can't get it to go any further than the charging icon is there a way to push files to it while it off? any help or suggestions are greatly appreciated
Same here. Can get into download mode but can't get into recovery. I've TWRP.
Ok made it into recovery.
Update:
I've now wiped Cache and Dalvik Cache and after rebooting it now says Android is upgrading / Starting apps.
Is this a good or a bad sign?

Just downloaded and installed via Odin a firmware version of this tablet and all is well. Just have to start all over again, currently writing this due to a Samsung update for the firmware. YEA!

Thanks a lot. I just registered at xda developers in order to be able to reply and thank you. You saved my tabS 8.4 two weeks ago. However, I lost this thread since that time and I just found it again today after almost 2 hours of google searching. All that to show my appreciation for helping me to switch off my tablet having been stuck at the booting loop.
I would send you money if I knew how. THANK YOU SO MUCH! I had this problem with a Samsung Tab S I got at Costco, and returned it for a new one. That was about a year ago, and I was sure I would have to take it back again. You are uberawesome!
Kindly help me if u can ^_^

Dear,
My case problem is like yours, after I wipe from TWRP I do restart my device & I'm now stuck on Samsung Logo or Battery Logo (if I plug it with my computer).
Now how can I download a new firmware, although I can't open download mode or recovery mode through (Volume Down+Home+Power)?
Thnx n Adv.

You have a couple of options.
1) Do as the guide says. It usually works.
2) If it didn't work, unplug your device and wait until it discharges the battery and goes off. Then charge it from USB, and turn it on with holding down Home+VolumeDown+Power buttons until DOwnload mode appears. Then press VolumeUp, and flash it from ODIN.

LG G3: Hidden Menu / MiniOS / Recovery Mode

Have you found and used the Hidden Menu function of the LG G3? Opened up Device Test, but stuck in MiniOS with a blank screen that has a circle with a + in the middle for each part of the screen you touch? Can't get into recovery mode? Got into recovery mode, but don't know how to get it to work?
Well I have done my research, and had my fair share of panicking thinking that I had bricked my phone because none of the advice online matched up perfectly. But if you have made that mistake yourself, here is how to unbrick and reset your phone.
1. Start your phone up by holding onto both the power button and the buttom volume key. When the logo pops up, let go for a second, and hold onto both buttons again. This should bring up the option to reset your phone. Agree to both prompts.
2. You should be on a new screen. It may warn you not to touch the screen because it is calibrating or testing it. You will have to press OK, and then give it a few seconds to do that bit.
3. The screen should have a list of options at this point (some of which say "+power) on them. If you want to use any of these options, you need to hold the power button, and then press that option on the screen. Press "normal boot (+power)" (don't forget to hold the power button at the same time). This should put your phone back to normal, and set it up again just like it came out of the box.
Hope this helps someone.

Skip the reinsert battery part in your item #1:
1) Remove battery
2) Hold Volume plus and minus keys down
3) Insert USB cable while still continuing to hold down those two buttons.
WIthin 1-2 seconds you should have download mode. When download mode appears, then re-insert battery. For sure you're not going into charging mode with no battery to charge. This is the method I always use, and it always works (aside from hard-brick situations, but you can access battery charging mode/graphics, which surely means that ain't you).
not works.

What does your computer say when you plug it in? If in Windows check Device Manager and see what your phone is being recognized as. Can you access the phone's contents via USB cable from your computer? Does ADB recognize it at all? Or does it just loop like that, not starting?
Also, it sometimes takes several tries to get it into download mode, as if you're holding the buttons down and not timed just right, the phone ignore your attempt. Make sure you do not let go of both volume buttons even after you plug in the USB cable, you must continue to hold them down for a couple of seconds (until the DL mode appears). Don't even think about putting the battery back in until you see that download mode box. Try that a few times maybe? If it doesn';t work ,maybe you're boned.

remove battery and place it again. then press both volume+ and Volume - . By keeping pressed both buttons insert your usb cable. don't release pressed buttons until its in download mood. by the way install unified adb driver for android by koush if your using windows 8.1 otherwise lg official driver is ok

Stuck in orange bootstate, no recovery mode possible!

Hi there. After (an attempt) to unlock the bootloader of my A50 and installing TWRP Recovery (TWRP_A50_Magisk_Prepatched) i find myself in an orange bootstate. I can't get it into recovery, download or fastboot mode. It seems like a full brick. I can't even power off the device. Only Volume up, Volume down and Power button let's the device reboot but then the same boot problems appear. Is there anything i can do to recover my phone?
Text of first screen when booting up:
"The phone's bootloader is unlocked and it's software integrity can't be verified. Andy data on this phone may be vulnerable to attackers. Don't store any important or sensitive information on this phone". Press power key to continue"
Text of second screen when booting up:
"The phone is not running Samsung's official software. You may have problems with features or security and you won't be able to install software updates"
Any ideas!?

Try connecting your phone to your PC with the USB Type C cable, and do VolDown + Power to reboot the phone, and the moment the screen turns black, press VolUp + VolDown. It'll bring you to a different screen where you can press VolUp to go into download mode for flashing the stock firmware via Odin. I got my stock firmware from https://samfrew.com/all/page/2/#t (you'll need to search for your Model Number - SM-A505F/SM-A505FN/SM-A505FM, and select the correct Region. Also, select the correct Modem Version (the last 4 letters/number of the item to download). Then, follow the "Flashing Guide" at the bottom of the Samfrew page where you downloaded your firmware.

You can find answers in the S10 forum. But I think the steps will be the same (this is A8 device/forum).

I HAD the same issue an I resolved it.
There are 2 methods to overcome this problem.
I even wrote a PDF and attached here in this post.
Below is SOME content from the PDF so it could be easy for users to find it on Google. I still strongly recommend you to refer to the PDF attached as it has pictures as well.
Samsung Galaxy M31 / Samsung M31 Screen is stuck on the following error message / error screen:
‘This phone’s bootloader is unlocked and the software integrity can’t be verified. Any data on this phone may be vulnerable to attackers. Don’t store any important or sensitive information on the phone.’
‘The phone is not running Samsung’s official software. You may have problems with features or security. And you won’t be able to install software updates.’ (error screen looks like below):
I was using correct TWRP and I was on Android 11 One UI 3.1.
Just to experiment, I flashed wrong TWRP version which was meant for Android 10 while being on Android 11. And so this problem started. Stuck on the error screen. Phone will not power off or on. Could not even enter the bootloader screen. Nothing works whatever keys I press. The same screen comes up. When the phone goes off and the phone will not accept charging that mean even you it whole night connected to charger, phone will not be charged- the same error screen.
So, the battery was not charging (my battery was at 24% just before this tragedy happened. It was late night and I thought of waking up tomorrow and plug in charger for an hour thinking if its battery is quite charged then I will follow Fix Method 2).
I woke up next morning and the phone was off (Battery drained fully). To this I was happy thinking that I can now hold Volume + and Power key and connect USB cable to enter Bootloader. When I did that phone would enter bootloader and gets switched off automatically (remember the battery was drained completely, charger too failed to charge battery and phone is not drawing enough power from USB port to stay on bootloader. On bootloader screen the phone’s display is fully on so more power usage).
Now I knew that the USB port is not proving enough power so that the phone could remain On while in bootloader when I hold Volume + and Power key and connect USB cable to enter Bootloader. I know for sure that Fix Method 2 will fix this for sure but it’s quite tiring.
So I referred to my PC manual to figure out which USB port provides maximum power. I found the right port (refer pic below):
So now I figured out 5 Volts port and plugged the original white Samsung M31 USB cable into one (refer the pic below):
If you don’t know which USB Port is 5 Volts then I recommend you to try all the ports and try getting to bootloader screen.
So when the phone was off, I pressed and hold the Volume up and Volume down key and with other hand I connected USB cable and now the phone went in bootloader and then I quickly flashed the right TWRP. Disconnected the USB cable and put the phone to charge and now it was accepting charge. Phone was back into life.
So I resolved it by Fix Method 1 below:
Fix Method 1: On my PC, I located the 5 Volts USB port and plugged the original white Samsung M31 USB cable into one (refer the pic below):
Entered Bootloader screen.
How to enter bootloader screen:
Assuming your phone is unlocked and the developers options are on and you have enabled USB debugging in Developer options and you have little knowledge of flashing firmware or TWRP via Odin.
Press and hold Volume Up and Volume down keys together with one hand and using other hand, connect USB cable to phone and release all the keys. Now phone will show bootloader screen which looks like below pic:
I quickly flashed the correct TWRP via Odin:
Flashing TWRP:
· Make sure OEM Unlock is ON in developer settings;
· Turn off the phone;
· Press the volume down + volume up button whilst the phone is connected to a pc to boot in download mode;;
· Long press vol up then confirm you want to unlock bootloader (this is needed one time only);
* Please be aware all your data will be erased including internal storage and phone will reboot!!
· Let the phone boot normally, pass the setup and connect to internet (wireless or mobile data) in order to unlock RMM;
· Make sure OEM Unlock is ON in developer settings;
· Turn off the phone;
· Use Vol up + Power + usb cable plugged to a pc to start the phone in download mode, short press vol up to confirm you want to go to download mode;
* If by any chance you see RMM state=Prenormal or KG state=Prenormal, factory reset data and redo from step 5!
TWRP screen was up. I tapped on Reboot and it did not reboot because the battery was not enough charged however I saw that TWRP Menu this means TWRP was working so the phone will boot up once it is charged.
Now I plugged in charger and was happy to see the correct charging screen (refer below pic):
I would turn power switch Off and On it quicky to know the charging percentage.
When it reached 20% I started phone (obviously by long pressing power key and it booted up just fine).
I loved myself
Fix Method 2:
Remove the phone’s back cover.
Be careful while removing the back case as you could screw the finger print sensor.
Disconnect the battery connector from motherboard and reconnect it.
Do not turn on the phone. As turning On will again get you back to the same error screen.
Put the back cover on.
Connect charger. Do not turn phone On yet. Wait for 5 min.
Do not even touch the phone.
Now you need to know the percentage of charge so do not hit the power button yet instead locate the main switch to which your charger is connected. Quickly turn Off and On and look at phone it shows charging percentage.
Once charging percentage reached around 20% you can touch your phone and power it on and it should boot up fine. It should not take more than 5 min to boot up.

I HAD the same issue an I resolved it.
There are 2 methods to overcome this problem.
I even wrote a PDF and attached here in this post.
Below is SOME content from the PDF so it could be easy for users to find it on Google. I still strongly recommend you to refer to the PDF attached as it has pictures as well.

Hi, friend. I have the same problem. But I don't even have a bootloader. When I log in, I just get a black screen.

Collection of mode entries with hardware key combination (maybe for most LG models)

This thread only introduce hardware methods to enter specific modes, however, if possible, use software method like advanced reboot, adb reboot, magisk reboot, etc. instead for stable entries.
Force reboot: hold both volume- and power keys for 8 seconds (maybe reboot at the 9th second, so hold until the screen changes). This can quit any other mode. Somebody says if you can count time accurately, you can just shutdown the phone instead of rebooting, but I have never succeeded
Normal boot: when your phone is off, hold power key until your phone vibrates (if your phone can boot to system).
Safe mode: during normal booting, when you see the dynamic animation of LG (not static monochromatic logos), hold volume- key until the phone vibrates (you can start holding it even earlier, but make sure holding it until you really enter the safe mode). In this mode, only system apps, default settings and basic functions are enabled. Any reboot quits this mode.
Recovery (stock for master reset or custom twrp): hold volume- and power keys until the initial boot screen of "LG V30" with "powered by Android" displays. (If you have unlocked the bootloader, this screen would display twice, but only the first time is what we are talking about.) Immediately release the power key and hold it again (in other words, pause holding the power button for less than 1 second). Then after the screen changes, release all keys and do further steps according to the instructions displayed.
LG download mode: shutdown your phone first. Hold volume+ key and connect the phone to a working computer via USB. Then the phone should boot to download mode.
Fastboot/Bootloader (if any): similar like the download mode, but use volume- instead of +. However some firmwares may miss this mode. If it works, it should boot to the fastboot interface immediately and you can power off the phone there.
Information screen (I don't know what it's called exactly): shutdown your phone first. Hold all the three of volume+, volume- and power keys, and this will lead you to a screen listing MEID, IMEI and S/N of your phone with corresponding barcodes.
Qualcomm 9008/EDL/QDLoader mode (sometimes even called Qualcomm download mode, but not Android download mode) (mentioned in One way to force shutdown your phone, try this if other modes do not work): connect your phone to a working computer via USB. Hold volume- and power key, around the moment your phone force reboots press volume+ for multiple times (with holding other keys). In device manager on the computer, see if a device named something with "Q" like QUSB_BULK (no proper driver installed) or Qualcomm EDL HS-USB 9008 (proper driver installed) other than anything containing "Android" or "ADB", the phone enters the 9008 mode. If not, unplug the cable and try it again. This can turn off the screen. If you find difficulty to perform it, you can also try other more general methods like test points shortening (see test points lg v30 plus for 9008 mode) or engineering cable (not tested yet).
Yet there is no way to shutdown the phone directly with simple key combination, but you can refer One way to force shutdown your phone to make it if you cannot use regular methods to shut your phone down.
If anything missing, please reply to let me know
