any help is gratefully received.
i was doing a rom update(pugs) and the unit has become stuck in what i think is bootloader mode. the screen is dark and displays "serial v1.01
after much searching on this forum i tried to hard reset then run maupgradeut again.
problem is that activesync no longer detects my device.
ive tried pressing power/reset/action buttons to no effect.does this mean i now have a pretty coffee coaster.
now you were at bootloader mode. try remove the device n put it back on cradle, for sure windows will detect it. after that, try run the upgrade again. The problem that you're having now are same like me when I first bought my device. The answer is good being a newbies n ready to ask question at here. hahahahah
thanks
now youve hit the nail squarely on the head. i thought i knew enough to update but when its gone boobies up realised i dont.
ive tried resetting the device and then connecting to my pc several times with no success.
anyone know how to take the device out of bootloader mode. im hoping theres a backup stored on the device that will boot...or...anyone know how to get the pc to recognise the damn thing before i launch it out of the window(all the way to an o2 shop).
im sure im not alone(can hear the voices)
took some brain power on my part. turns out microsoft activesync was the problem.
upgraded to the latest version and everything went as it should.
Hello, Im pretty sure youve heard the story. Dropped my phone and cant see a thing due to the cracked screen. When I plug the phone into the computer, the computer recognizes it because I can hear the chime. But I cant unlock my phone to get all of the data off of the internal memory. Is there any software I can use that will act as a virtual monitor on my PC, like a developer kit or something of the sort? I looked in another thread and a guy recommended a OTG cable, but I dont think that would work in my case because I cant see ANYTHING on my phones screen. The repair guy at the shop said that the screen and LCD is damaged so....please? Any help or redirection to another thread would be greatly appreciated. I have all of my music and photos on there and I dont wanna send the phone back yet without trying every possible way to recover the data. PLEASE help. Thanks.

If you have not done anything in advance on the device it might be hard.

Hello there,
today, it just happened out of the blue, my pretty new S7 does only show up a blank grass green screen now! It can be turned off and on, touch works. I just can't see anything at all anymore. I really need a way to mirror the screen to the PC or something... USB debugging is not active :crying:. There are some apps installed, I need to use because I have to create the backup files in them!
What would be the easiest way to get access to this?
The phone is connected to my WiF if that helps.
Thank you so much!
I need help really urgently. (
Put it in download mode and reflash in odin

If you can aquire a mhl cable for your s7 you will be able to output the video output of the s7/edge to a tv/display. Just search mhl cable for s7 edge on amazon or ebay and you should be good to go.
Edit: just read the s7 and the s7 edge don't support mhl so you might be out of luck.
@Rydah805 I want to backup my data .... and I don't think that would help at all. The screen is pretty much done.
@amar95353 I read online that there is no more MHL support on the S7 anymore.

Your SOL on data. You can try SmartSwitch on PC but even then you'll need to approve the backup via the phone.

Original answer deleted. I'm a complete idiot. I should have checked but believe I was given incorrect information from my sprint sales person on location of reset. Sorry.
I turned off the phone many times.
Phone works fine, just the screen doesn't. I found a lot of forum posts for this problem it seems common...
I didn't root this phone.
Now, I finally know what's the hole for LMAO! What does happen if I poke it? Update: Hey, that hole is not used for resetting the phone. It's for noise reduction.
I don't think this will help on a broken screen anyway.
slaldrich said:
i assume you turned your phone completely off and on again (not just the screen).
If you did that, did you try a reset? There is a little hole on the top of your phone and in your box, you received a little tool. Poke the hole and hold it in until something happens (a few secs). This sort of reset is like pulling the battery. You should not lose any data in doing this.
If you created this problem by trying to root your phone unsuccessfully... Then you will probably need to odin new stock software.

please dont put anything in that hole. This is not a reset button............... ITS A MICROPHONE and that tool its design to open the sim card bay.
Don't worry, I wont do that.
I'm so stuck here... and also I need to send this phone to T-Mobile! Right now I 'm using an iPad as a phone replacement. lol
Just wish I could save this data...
Is your screen experiencing this?
http://i.imgur.com/iOmtR2T.jpg
If so, it's a defective screen.
I got mine replaced already since it was under 30 days replacement guarantee. You can read more about it here: http://forum.xda-developers.com/showthread.php?t=3359221
But the bad news is you won't be able to backup anything. I had to sacrifice a lot of stuff as well.
This is exactly what my screen does look like! And I did not only had problems with the screen, I wasn't able to get my carrier's settings automatically, I have problems with the charging, it won't display my phone number in the settings and also sometimes the camera app freezes. I installed the updates which didn't change anything. This new smartphone which doesn't even has a tiny scratch, never fall down is totally wrecked. Really disappointed about this "top high end" phone. I don't trust, that it will work after they "repeard it". I have it since release.
It's like really a huge amount of data... Of one app it is everything from 2 years (7GB)! There is no possibility to create a backup, you can just send the data to a new phone via WiFi that's all. If your phone breaks everything is lost.
I realized many app developers don't take enoughh care of backup solutions.
Yesterday the screen got back to life but just for a short moment
So it seems like there is no way to get back this data...
Can I get back my WhatsApp backup at least? I was able to create a backup before the screen died. When I plug in the phone to PC I can see "Samsung Galaxy S7 Edge" in my explorer an that's about it. When I click on it there is no content to show.
I just got an idea how to enable the god damn USB debugging!
Can someone share here how to connect the device as a mass storage to PC (by screenshots please)!
I was just thinking, I can work my way to the Developer Options by taking screenshots but I need to access the media for this!
When I connect the device to PC and then click on Samsung Galaxy S7 Edge it's empty... There most be done something before.
Thanks!
You guys can call me a ****ing genius! I managed to install Teamviewer by taking screenshots and look at them on the PC (I set up the device as mass storage blindly) so I knew what to do next. It was still tricky but possible.
I'm recovering my data now.
Thanks to the Google voice app I was able to type in "Teamviewer"
Thank you anyway!

It wasn't really easy dude... The most difficult was to make this damn thing work as a mass storage device. So I could finally have access to the data on the Windows Explorer.... I was just touching on the screen like a maniac!
But this is a way to do it guys. If you own a Galaxy S7 Edge I recommend to activate USB debugging and install Teamviewer quick support (Samsung version, there are different editions) just in case the screen breaks. lol I install Teamviewer on all my devices now...
Hey! The same thing just happened to my phone an hour ago. Green grassy screen. It's terrible!
Ok, so what were the steps you took in order to get to where you can turn on USB debugging and backup your phone?
Well, what happens when you connect your phone to your Computer (USB)? If nothing, then you need to check connect the device as camera or mass storage, blindly! Which is kinda tricky... You need to pull down your notification bar and then select the USB options thing and in this menu which pops up you need to select camera or mass storage... But once you get that done, you're good to go! You will be able to take screenshots and view them on your computer instantly. You don't really need to care about USB debugging, you can just get Teamviewer Quick Support (for Samsung) that is really important, the normal version won't work!

Thanks for the reply. It actually looks like my issue was much worse. My phone degraded pretty quickly, since I wrote my post. It got to a point that while I could type on my lockscreen, it wouldn't go past and enter the OS. I didn't even have a green screen anymore, the screen turned to an off black. At that point, I gave up and sent it in for repairs. I think the motherboard got fried.
well Yeah.. so i bought this stick just now on ebay thinking it should be good enought to give away for streaming some live tv and so on, but
this had obviously the WIFI problem and there i was..
Not beeing able to use WIFI i started to search for different roms and after a couple days constantly searching HOW TO- and downloading different ROMS and watching youtube on how to flash i set up to the task once again..
Beeing able to flash both Nvidia tablets, Samsung Telephones, and Xiaomi i felt confident that i would be able to fix this..
But no, i had a couple different roms that started up With start screen but then that was it, nothing more i couldnt get past start boot logo on either of the 3 roms i thought was correct so i startd to search for same chip roms as this has the 3229 rockchip and the AS something number wifichip..
But then after flashing With a unknown rom it wouldnt start up again or even get recogniced by the computer usb again..
I tried the reset button, i tried shortcutting pin 6-7 and most likely all other as well but no Luck..
There is a blue light but its only halfway as Bright as when the stick was ON and working.
So its like its stuck in some low Power recovery or i dont know..
At least it lights up when i plug it in.
this is the stick With the red "plastic antenna"
Its not an antenne after all by lokking at it but maybe it serves some purpose of making People think its an antenna..
Any suggestions will be apreciated as now i consider it as Waste and after just spending 35 USD on it i would like it to at least get it back so i can sideload some games on it and give it away rather than putting it in the trashcan..
I attach link to the crap i bought so you get the idea of what it is and to also avoid..
Thank you all for all help!!

Hi.
I think I have the same device as you. And also I tried to flash another rom without success, so until I find a good rom, its just a small brick.
I also been in the same situation as you, but you have to short pins 7-8 to revive. Its the pins facing the middle of the device, and counting from the device edge/side.
Good luck. If you find a working rom for it, let me know
No, i have had no luck. Piece of **** device.
Got 80% refund from seller after a couple weeks of complaining.
Just throw it away and buy a ZAPPATI media player or a Nvidia shield if you dont use any 3D.

Hi again.
If you ever revive your dongle, you can get a working rom from the following link:
http://freaktab.com/forum/tv-player-support/rockchip-based-tv-players/rk3229-devices/firmware-roms-tools-bg/623420-mk809iv-rk3229-bricked-how-to-unbrick?p=646882#post646882
It worked for me
Thanks. I will try. Any tips in how to revive it??
I also have an mk809iv. I couldn't get developer options to show after tapping build number but it said "no need you are already a developer" (I assume its preunlocked?) I got bored and decided to flash a rom. I have the rockchip factory tool and rockchip batch tool. I tried flashing an update and the problems began lol
OK..... The stick now doesn't have a blue led on AT All. Tried original mains power source different USB cables different ports on laptop etc.
When I connect it to the TV it doesn't show up on the hdmi. Have I really fried it properly ?
Is there a way to use command on pc or adb shell or something to unlock the bootloader. In batch tool I can see the device after shorting pin 6/7 method but when I load firmware and start to flash then it comes up with failed at boot every time and on different versions of the tool.
I rooted the device before with King root (not king o root) and flashed supersu via rom installer app. Assuming that developer options are open by default, the device should be rooted now...... Right? ?
Anyway is there a way to uninstall all the software and reinstall the manufacturers firmware via the pc ? I have included pics of the board, but when looking at other people's pics the have a lot more chips and nand chips etc mine has one chip on the back and on the other side what I presume to be a heat sync (look like a bit of a tin can
Lol)
I have been on many forums for about 48hrs straight now ? and still can't find answers *sigh*
Recap:- 1 is it fried
2 if not can I sort it via pc
3 HOW?! lol
One last thing, would it run on cyanogenmod 11 ? it's an android device running kit kat and my gingerbread S2 is now on cm11 or are the internal "gibbons" different ?
Many thanks to anyone who can lend me a hand ??
Hey!
While I was calibrating my fingerprint, phone suddenly turned off and went to recovery with screen off.
I managed to reflash stock rom through fastboot and it boots to system fine, but the screen stays off and the front camera keeps trying to open while playing the MIUI camera sound (sometimes, while booting, the camera does manage to open once, kinda like it's calibrating). Some playing around with ADB and it seems that the SIM isn't recognized either.. antenna maybe?
I opened the phone up and checked everything, there's no visible issues with the electronics, however it could just be the inside of a cable that died?
Does anyone know what this could be? I noticed the screen, fingerprint reader and antenna are all connected to the same removable PCB, but the camera isn't so that's odd.
Aren't we moving way too fast here? Like wtf is happening rn?
First: Explain in detail from the beginning please if you want help.
Second: Please state exactly what is your issue, and the ROM version of your device.
I don't think what you just did is the cause of whatever problem you're facing, do you mind telling me the source from which you got this phone? Otherwise you might want to send it to a service center.

It's a bit of a long one, so I didn't want to bother too much with the details if anyone knew what those specific issues could be caused by, here goes though:
I am on a Mi 9T bought on Amazon Italy in July 2019. I cannot comfortably send it to a repair center due to every authorized shop around here is just a drop-off point for Xiaomi RMA. I talked to them and, due to (>6 months old) glass damage to the screen and back of the phone, they intended to charge me way more than I can afford, as "solving issues covered by the warranty would require us to replace the accidentally damaged components"
As for what happened:
I was running LOS 17.1 with no issues for a few months. I went to unlock the phone and I heard the reboot vibration, which sent me to recovery (softbricked) but with no screen signal. I assumed it was just a software problem, so I flashed MIUI 12 (global, V12.0.7.0.QFJMIXM) to see what would happen.
As it completed, the phone rebooted itself, the MIUI logo popped up and it went to system (seemingly) without any issues.
I went through the initial wizard and played around with it. everything seemed fine and I even made sure the screen did work in recovery and fastboot. Later, when I went to setup the fingerprint reader, the screen went blank for half a second when I first touched it, and then the same screen death -> reboot to recovery.
The phone was softbricked again, though, this time, reinstalling MIUI didn't yield the same success. Now:
MIUI boots "normally" again
The screen isn't working at all
The front camera opens, as if it's calibrating, when system boots up
The front camera randomly tries to open again every now and then, failing to do so as if the motor is stuck, while MIUI plays the camera closing sound.
Meddling through ADB, the antenna doesn't seem to be working, but I can't be 100% sure due to the methods used
The power and volume buttons, speakers, and the charging light all work.
I have opened the phone up myself, thoroughly checked every cable, connection and PCB, but there is no sign of damage. I put it back together and the same issue continued.
My best guess is that something inside the fingerprint reader went bad and shorted something else.
What that something else is, I couldn't find out. Given the antenna, screen and FOD are all connected to the same little PCB which then runs a couple cables to the motherboard, I am now in the process of finding a couple replacement cables to see if that fixes anything.
As I mentioned before, repair centers are not an option due to the lack of anyone who's willing to help me for less than a good chunk of the price of the phone.
Interesting. So basically what happened is due to the initial soft brick and accordingly you flashed a global MIUI 12 ROM, which in return brought you to the second soft brick which caused some issues within the hardware of the device.
Now you're stuck with a faulty screen, a faulty camera and a faulty antenna.
I don't have the skills to play around with the motherboard and the phone circuit. And I don't care which youtube tutorial you saw, you should have NEVER done that - Of course unless you're actually experienced in that manner, then I apologize for speaking with such prejudice -
I can't help you if you messed up your phone circuit since I have no knowledge about android hardware, however I can safely assume that what caused your issue isn't related to hardware.
I think the issue is caused by an incomplete flashing of a ROM (In this case MIUI 12 global) OR flashing a different variation from your device.
e.g. you flashed only the ROM, but didn't flash the other components of the ROM.
Needless to say, flashing a variation of the ROM that isn't meant for you device can be a disaster recipe.
I recommend flashing LOS again, since you can't go back on Xiaomi devices due to rollback protection.

I understand why you'd think that and have seen people do similar stupid things, however I didn't watch any youtube video and know what I'm doing quite well.
I made sure I flashed the correct rom through fastboot to restore everything to stock. I did try to reflash LOS and whatever else (though it's kind of a pain with adb shell), but it doesn't fix the problem, sadly.
That's why I'm betting on a HW issue.
The fingerprint reader and everything else worked flawlessly in LOS for months, but it made the screen go blank and bricked the device in both LOS and fully functional, stock MIUI.
Currently, I'm battling with this damn thing to get USB debugging working while booted to system, so I can do a few things like cast the screen to my PC and see what works from there.
I have access to fastboot and recovery, but everything I know (editing build.prop or patching the boot image) didn't work so far. Do you have any idea what I could do to get that done?

If the touch screen is dead then you can use mouse and OTG cable.
If it is completely black then you can get usb c to HDMI cable (Also usb c hub might work, like this one). Or you can use playstore on pc to download and install apps like (Screen stream over HTTP) on your device, just make sure your device is connected to the internet and you're signed in on your phone as well, you might have to type in the screen password if you have one.

I don't know why bother with build.prop unless you have the wrong fingerprint prop. Then you can get the correct one from your device's stock ROM, though I think this is irrelevant to your issue.
All I can think of is:
Wiping dalvik cache, though you might have already done that.
Trying other custom ROMs from here.
You may try to get your device rollback index and installing a MIUI ROM that has index higher than it, and see if that works.
That is as far as I can help, unfortunately.
I have zero knowledge when it comes to hardware, so I can only help with software issues. If none of my solutions worked then sorry for wasting your time :/

Wait, does it actually just automatically use it as a 2nd screen if I connect it via HDMI?

Sorry, I didn't explain myself, I'm looking for a way to enable USB Debugging without a screen. Thinking that using adb in twrp is the best way, but I can't manage to do it. Do you have any ideas?
If I can get it on, I can then use things like scrcpy to get screen signal through USB.
Main problem with everything else is that the screen is 100% dead. Even with usb otg I don't know how I could possibly get through the setup wizard haha

I haven't tried it myself, however it should detect it as a second monitor. Give it a try the cable isn't costly at all anyway.

TWRP has debugging mode on by default, however that strictly applies to recovery and fastboot modes only as debugging mode is pretty powerful and can cause security issues. So you better forget about it.
I saw one of my friends who owns an authorized service center use some cable connections to get the screen to display on another touch screen. If you have the capabilities and resources I recommed trying it, though don't mess too much with the motherboard.
Just a question though, can you confirm if the touch is working? If not then there's a chance - Although slight - that this is just a UI problem (Which is pretty common in MIUI ROMs for some reason). In that case deleting dalvik cache or completely reflashing the ROM might solve the issue.
I may not do much help but certainly someone there can help so it's better if you include "usb debugging" in the title and/or the tags. Like changing the title to "Enabling usb debugging without screen" or "Screen is dead, need help to flash ROM"
Using proper title and proper tags can get the right person to help.
