Phone reboots constantly with blank screen and No touch capability - General Questions and Answers

I recently bought an MTK6573 S820 (T9199+) Android phone.
I was following instructions to update ROM in order to improve 3G service. However after ROM applied and phone rebooted the screen was blank. only back light comes on.
The phone constantly reboots and I cannot get to so anything on it.
Is there anyway I can flash the phone with the original ROM or something? I am desperate as the phone was pretty nice and I really liked it.
Please Help.

Can you get into the bootloader menu? I have never heard about your phone, but should be holding the volume button while turning on the phone.

I don't remember the version of the bootloader version of the few times that I went into recovery mode before I am seeing nothing on the screen.
It loads up as if everything were ok then it restarts after a few seconds. That process loops.
I am able to use adb tools and confirm that the phone comes up in recovery mode.
If I were able to remotely run the update.zip remotely I may be able to restore the phone. I am also unable to flash the various ROMS using SP Flash Tool. I am hoping you guys can help me.

I have the same phone and also noticed that the 3G is not 100% where did you get the new ROM from as I have been in contact with supplier an none available?
I have been having a problem with a noise coming from my phone to the other party but not on every call it also fades in and out, they can hear a buzzing sound or like a helicopter noise but i can hear the other party ok , so just stripped the phone down and cleaned all contacts also moved a piece of mesh tape covering part of the Mic and so far no problem , but being at work will test that out tomorrow
it would be nice to be able to turn the Mic Volume up a bit (any help ??)
I rooted this phone about a month ago with super one click and put link2sd and freed up internal storage this extra partition on sdcard which works just fine

Apparently that was my problem. There seems to be a number of phones that have the same model number. I pulled a ROM from the site that I got from a document that came on the mini-disc that came in the package. Apparently it was the wrong ROM which threw my phone off. Even though the model number and specifications were the same.
I have sent my phone back to my re-seller for repairs in China. I await feedback from them soon.
I recommend not installing any update for the phone as I am not sure. There is a guy Bruno that does custom ROMs for android phones and he had done a ROM for the phone I imagine but stopped development due to no funding. I am not sure if the ROM he had was for the same phone.
I wanted the update to assist with the 3G service as the guys were promoting that that was a part of their upgrade.

[Q] Nexus S goes into some sort of fault state

My two months old Nexus S started to behave in a way that renders it pretty much useless - Freezing / Locked U
Freeze/Delay Between Menu and basically the phone is dead.
Very often when the screen is off, pressing power button powers up the screen with the screen lock, but the phone is not responsive so the screen just goes off again as it is impossible to slide to unlock it.
On top of that, leaving the phone with the screen off for a half an hour or so brings up some sort of warning sign and a small android (can see the screen shot here: http://yfrog.com/h3apmgqj) and the phone is effectively dead. The only thing to do in any of the two cases is remove and reinsert the battery, but that is no solution to anything. All this is while the battery is fully charged.
Did anyone experienced this before? resetting phone does not help.
Here is more info on this topic: http://www.google.com/support/forum/p/Google+Mobile/label?lid=4e31a500f89fe575&hl=en
Are you using a custom recovery/ROM? That icon you posted isn't the stock image
Hi, no I do not - the image is actually from different phone but it looks exactly as it did on my Nexus S (little green guy with an exclamation mark). I never rooted my phone or done any custom mods to its system.
I actually sent it to Samsung and they are claiming that they found no problem, so they re-flushed the phone and are sending it back. I am seriously angry at samsung. It is arriving on the 11th so I'll let you know if that helped but I doubt it.
I believe this might be a faulty memory because I often received notification that the internal storage was unavailable or something of that nature as well, right before the problem would occur. Are the any tests I could perform for memory / storage?
just try to flash it back to stock
then do wipe data and wipe cache
see if that gets it back on its feet
Hey,
thank you, I thank that means I would have to root it first ehhh
Samsung told me they've done just that (flashed phone) so I am seriously hoping that my phone will work when it arrives on the 11th.
thanks!
Samsung supposedly is looking into this problem, please see link below:

Update:
I just received my phone from Samsung repair and of course, the phone is NOT fixed. On the side note, they also sent back my note that explains the problem meaning it was ignored completely.
I will be contacting @SamsungServic and calling but at this point I am not sure that they can fix the phone other then replace it.
Also,
I've spoken to Samsung and chat online and - yes they nice and throw back lots of promises and niceness back but they are NOT doing anything about it, for now at least.
I copy and paste the best answer on the google support topic to here:
I've been keeping a notebook to document my debugging of this problem. No app in particular is responsible, in my opinion. I have observed the phone lock up after a Factory Data Reset + USB wipe, and with no accounts configured. In fact, I have had it freeze after following this procedure:
1. Factory Data Reset + USB erase from Settings menu
2. Phone reboots.
3. Go through initial setup screens, skip account setup.
4. Power down phone.
5. Remove battery.
6. Remove SIM card.
7. Replace battery.
8. Power up phone.
9. Let phone sit for 15 minutes or more.
10. Phone freezes.
This is about as close to bare bones as I can get with this device.
I have also documented at least four freeze modes:
1. Phone is completely dark (both display and buttons). No combination of power button or other buttons can bring phone back. Battery removal required.
2. Phone display is dark, but the four "hard key" buttons are illuminated. No combination of power button or other buttons can bring phone back. Battery removal required.
3. Phone displays only a green android by a warning exclamation sign. Holding power button down, then volume up, then release volume up, will bring up the Android system recovery screen, from which phone can be rebooted.
4. Phone is frozen at the unlock screen. Sometimes this freeze occurs while swiping the unlock icon. No combination of power button or other buttons can bring phone back. Battery removal required.
I have observed the phone going from normal standby state (display and buttons dark) to state 2, and at other times to state 3, while it was sitting on my desk by the keyboard.
I'm just about ready to send it to Samsung. I just wanted to verify that the problem would be reproducible after a factory reset and without the SIM card.
I think it may be a hardware problem. It's also possible that part of the Android kernel or some device driver on my device has become corrupt. Unfortunately I can't reset the OS.

I did a factory reset from the stock recovery, too. Doesn't help either.
My phone arrived on Friday Samsung mobile repair in Texas. And like they did to ohter Nexus S devices from other users they will do the following to mine:
Reflashing the phone -> doing some functional tests ...
... and this is the crazy thing about it. The error we have is just appearing when the phone is in standby and because of this the phone passes the functional tests Samsung is doing at the end of the service. Phone goes back to user. A defective phone.
Some guy managed to keep the phone alive by setting the display turning off after 30mins. He is charging it twice a day
I got a reply from @SamsungSupport on twitter:
Thank you Fabian for again reaching out to us. We are aware of this issue as some of us have your same phone.
An evaluation is already being conducted to determine the fix. We don't have a timeframe of the resolution.
But understand it will be pushed to phones. We will advise once we have a timeframe.

The support team is friendly and to me it feels like they try to do anything they could.
Funny: One guy got a replacement device. But then no one other. Just reflash...
I think they will do something but on the other hand I'm worried that they will do nothing. But time will tell....
Maybe it would help us if Google will be aware of the problem, too. Ok maybe they allready know it, but I don't know that.
So if some of you here do have some connections... please do us a favor and forward this topic or the link to the google support topic. Feel free to forward this topic to any website you think it would write a news about it. Maybe Google will throw a eye on it. My phone is 8 weeks old and yeah this so anoying. And of course all my friends who are iHippster are trolling me like hell.
It don't want to flame or blame Samsung\Google for this.But our phones are in warranty. The error hits only a few devices and so they should replace it. My 50cent about it... this is not a Google expierence they talked about...
I also had the same problem and sent my phone into Samsung. They only re flashed it, which didn't fix the problem. I immediately called Samsung to inform them that the issue was not fixed and they just told me to send it back for "double checking." Do you think it is better to send it back in or just wait for fix to emerge?
I will be sending it back and demand replacing the phone, also making sure they just don't re-flash again. I guess anything but re-flashing could work.
Remember that I've mailed my phone with one page letter explaining the problem. Their response was flashing the phone and sending it back - with my letter.
Here is note from the support team:
----------------------------------------
Original Problem:
Technical Inquiry
Phone Freezing / Locked U
Freeze/Delay Between Menu
Problem found:
NO TROUBLE FOUND
SW,PRL,OTSL RESET
Solution:
Passed All Functional Testing
--------------------------------------
@Samsungservice did not even acknowledge it officially that this is a problem.
Yeah i wrote a letter too explaining the issue and how to recreate it (the first time). They told me that it passed their quality assurance inspection after re-flashing it, which must be very poor because my phone shut off again 15 minutes after receiving it. Just dropped it back off at UPS today. Can they replace the phone because of this issue? I know one person had success, but it doesn't seem anyone else has.
Nexus S faulty
Samsung may not be able to reproduce it after reflashing; as this issue does not seem to occur when connected to a PC/computer via USB. Their automated testing could be over USB.
Looks like more and more people are facing this issue as the day goes by.
Search for "Nexus S fault state" on google and you'll find the google support forum thread discussing it
Guys,
Did anyone have tried to flash a custom rom to see if this will solve the problem ?
cheers !
No, but this problem is not ROM related.

I figured that was why they couldn't recreate the shutdown. Made sure they knew that it has to be unplugged. Mine always shuts off within 10-15 minutes if untouched.
I have same problem.Only remove battery helps. I have been having nexus s for 2 and half months and this problem just came last week. I don't know how to solve it. I tried reflash firmware but didn't help.
welcome to the club. you have to send it to USA to get it serviced (make a extreme detailed problem description and make sure the support worker writes it down 1:1 into their ticket system). they provide a 2day ups shippment label, BUT only to locations in USA.
I can recommend FedEx. They helped me a lot with this duty stuff for shipping to USA. That's not so easy . I paid €50 to get it shipped to a friend of mine in USA.
You have to send only the foreparts of the device. No battery and back panel, no charger and so on. But they will give you all informations at the end of the service request.
or: wait for a hotfix. which maybe never will come.
Update:
I just mailed my phone again... they told me they do not replace phones (not sure what that means yet). The Rep was arguing that if I want the phone replaced then I need to talk to T-Mobile - it does not make any sense.
Anyway, I explained the problem as much as I could and did not mail any notes this time as they obviously do not care for it. But I made sure he included every detail in his notes.
I am very skeptical but still hoping....
Also,
About the part when the phone does not freeze when plugged in or charging. I had my Nexus S charging overnight and it was frozen in the morning.
Update:
Also, I've contacted @SamsungServic via Twitter and asked if their team recognized it as a problem, but I've got no response.
On the other hand if you report the problem to them, they will respond that they will look into it - which means nothing, but if enough people asks the same question them they will have to.
-thanks
I've got some sort of responce via Twitter from @SamsungService, here is what they wrote back:
@SamsungService
Thank you for reaching out to us. We are aware of this issue as some of us have your same phone. An evaluation is already being conducted to determine the fix. We don't have a time frame of the resolution, but understand it will be pushed to phones. We will advise once we have a time frame. Thank you. ^Mary
@Keinam
Does this mean we should stop sending our phones back for repair and just wait for your OTA update? If it happens?
@SamsungService
Many issues can be resolved with warranty service. Regarding the issue you've referred to,It is my understanding that a fix if being worked on which would be sent out OTA. ^Mary

The blue light of death... No screen no safemode no boot

I've had my Samsung up and running for about a week now , did the two most recent updates . Today is the first time I experienced some serious problems . It started with a fingerprint scanner not working delivering an error message that read "fingerprint scanner has stopped working restart phone if this repeats" so after my second time of dealing with this there I restarted the phone . P at this point in time is when the blue light was lit up and has stayed lit up since I restarted it, this has been about an hour. I've tried every option on the recovery menu except factory restore. When I turn the phone on safe mode or not it goes straight to a black screen with the blue light continuously lit up . When I turn the phone off the light never turns off . I've tried hooking it up to the charger and doing all of the same steps above and still no luck. I have not installed any unknown apps other than ones on the play store and haven't had time to even explore rooting or ROMS yet. Seems to me like a brick by the stock software don't know if anybody else's experiences but I don't know what to do . Maybe someone can shed some light before I consider doing a factory restore , if that will even work.. I think this thing is bunked.
Edit~ I also tried pressing both volume buttons the power button and the home button all at once and it took me to a blue screen with the android logo and Galaxy written on the bottom . Nothing for a few seconds then it's says erasing and reboots....still a black screen and a solid blue light.

What firmware are you on? If you've taken the most recent updates, don't worry about rooting. Probably won't happen at least for a while. If you have a warranty, I would use it. If you get a new phone, don't take any updates if you might want to root.
If you want to keep this phone you should try the factory reset or the emergency recovery in SamsungSwitch.

I'm not sure which firmware was on it, I did not pay attention before I took the update. I do know I have taken 2 updates in the last week since I received the phone.
I took the phone to a Verizon store and of course, seemed like going backwards. The rep tried all the same things I had tried and ended up calling a customer service rep to help him figure out what to do. Because the phone was purchased online my business' HR lady had to order another one online( which they replaced for free). Not sure what the problem ended up being but I know personally the most recent update BRICKED the phone.
New phone is up and running and thank you about the advice to not update if I prefer root. I love the stock ROM so I was really only going to root to de-bloat alot of the stock apps that are repetitive (i.e. messaging, messages, and Hangouts) .
So as of now no known fix to this blue light of death, except get a new one.

Check out your firmware in settings, about phone. If your build ends in OC3 or OE2, it can be rooted.
Glad you were able to get a new phone.
OC3!!???

Hard Bricked... Pls Help!!!

Recently, I bought the LG Stylo from Boost on Craigslist. Before the transaction was completed, I checked the IMEI and everything checked out clean. Like a lot of folks here on this site, as soon as I got home, I attempted to root. Prior to me rooting, I got an OS update to marshmallow and I went ahead and did it. Once the update was completed, I rooted with Kingo Root and root was achieved.
Not long after (within 24 hours), I noticed that my phone was getting very laggy and choppy so I decided to reboot. When I did that, the "LG Life's Good" boot image showed up like usual. Then the screen went blankb and turned back on to the boot image but the bottom said "SECURITY ERROR" then couple seconds later z the screen goes off again and it comes back on to the previous boot image. It pretty much is doing a boot loop. Initially, I was able to access the stock recovery and I did a hard reset but that didn't help because the outcome was the same. Then an hour or so afterwards, my access to the stock recovery was gone. Now when I try to boot recovery, it says LOADING RECOVERY but then instead of going to recovery, the Android guy pops up and right below him it says ERASING then it boots into the boot loop cycle.
At this point, all I can do is boot into download mode and from my understanding, all I can do is install the firmware. Since I was on Marshmallow, I looked online for days for the boost mobile 6.0 stock firmware. What I failed to realize is that what I found was completely not meant for the boost mobile 6.0 variant instead it was for T-Mobile 5.1.1. Yes, I made the mistake and flashed it the LG Support Tool and yeah... Stupid move because now my phone is completely bricked. Nothing comes up on the screen no matter what hard key combo I try BUT what's weird is when I try to power on my laptop makes the sound that it detects it but a box on the screen for my laptop pops up and say that I need to unplug and replug the USB cord to fix and if that doesn't work, then that means something is wrong with my device.
I really like this phone. Any one can drop knowledge, I'll be forever grateful. Please help.
Damn that's all bad I just gotta Stylo and I was thinking about using kingroot to root it right now too

1st off, kingroot won't root Marshmallow yet, it only goes up to Lollipop 5.1. You got the temp root we all got using the newest kingroot. I used it too and I've bricked and sent my phone back to LG twice, because of kingroot. There are many others with this problem. You are gonna have to take a chance and send it to LG. You'll have to lie, and tell them you had a bad MM- OTA update. I wouldn't say anything else and make up a receipt, unless you can get an original receipt, or don't include a receipt, even though it asks for one. Some one on Android forums sent theirs in without a receipt and it wasn't a problem, I guess since stylos are not out of warranty since they haven't been in production a year yet. Go online to lg repairs, and/ or call them. There is no custom recovery for a boost/sprint/virgin stylo because it has a locked bootloader, so you'll have to take a chance or wait forever. If you send it to LG they will send you a prepaid label and if they won't fix it they'll send it back, That's all I got, Good Luck
Thank you jmacie. After you said that many other have this exact issue including yourself, I felt that maybe this isn't something that an average person could fix on its own and that it needs the knowledge of an LG tech. I called LG and requested a repair and I've filled out the request form and now I'm just waiting on the stuff they'll send to customers so we can mail it in. They said it takes about 5 to 9 business days before I get it back. During those days, from your experience of sending it in 2 times already, do you get an email from them telling you whether they can fix it or not or do you find that out when you open the box once they mail it back to you?

If you don't get an email soon about shipping your phone to them, call them again.They should send an email titled "Mobile device repair instructions" That email will have a pdf with the label to print and instructions to take out your sd sim backcover, it doesn't say but take out the stylus. Take off your screen protector or they'll throw it away. The email has a tracking link that you can check the status from receipt to return. I'm sure you'll be nervous, I was but you have the new marshmallow update causing many people problems kind of covering you up. I don't know how they might evaluate your phone, but you know you don't have any other choice, none of us did, so keep positive. LG has been great to me and that fact keeps me considering buying my next phone from them too.
And that is exactly where I'm at in this whole process. I'm waiting for them to email me that pdf document for me to print out and off the LG Stylo. My quick question is since you mentioned that you've mailed your phone in TWICE already, do you remember exactly how long it took each time from the day you mailed it in to LG to the day you got it back from them?
And yes, the MM update is going to kind of cover me and my issue because I've read more negative things compared to the positive so fingers crossed. Hopefully all those positive experiences you've had would transfer to me and my case. I've wanted the phone for a while abd when I finally got it, within 48 hours, BAM! this happens. SMH

It was 10 days total. After I filled out my form I called saying I couldn't wait around for a phone call as my contact # was my landline, and they immediately sent me the label. That live agent call did include questions about what happened. In my case I had told them that google services was stopping and after a hard reset I got a frozen on LG logo screen, which was the truth both times, but I'm certain the circumstances were aggravated by my messing with the build.prop and kingroot

but overall i got mine fixed for FREE and got it fixed and back within 4 days lucky me
but yea they'll fix it just depends on case by case i guess since my charge port had burn smell and marks gues that caused them to fix entire device and i sent it in with 5.1.1 and got it back with 6.0 so yea i say don't root till there safe proven method or till they let us unlock bootloader but till then just be happy with what you got

It pretty much is doing a boot loop. Initially, I was able to access the stock recovery and I did a hard reset but that didn't help because the outcome was the same. Then an hour or so afterwards, my access to the stock recovery was gone. Now when I try to boot recovery, it says LOADING RECOVERY but then instead of going to recovery, the Android guy pops up and right below him it says ERASING then it boots into the boot loop cycle.
At this point, all I can do is boot into download mode and from my understanding, all I can do is install the firmware. Since I was on Marshmallow, I looked online for days for the boost mobile 6.0 stock firmware. What I failed to realize is that what I found was completely not meant for the boost mobile 6.0 variant instead it was for T-Mobile 5.1.1. Yes, I made the mistake and flashed it the LG Support Tool and yeah... Stupid move because now my phone is completely bricked. Nothing comes up on the screen no matter what hard key combo I try BUT what's weird is when I try to power on my laptop makes the sound that it detects it but a box on the screen for my laptop pops up and say that I need to unplug and replug the USB cord to fix and if that doesn't work, then that means something is wrong with my device.
I really like this phone. Any one can drop knowledge, I'll be forever grateful. Please help.

you have to send it to LG.This phone has a locked bootloader, so there is no custom recovery, so you can't just mess with trying to use tools made for tmobile unlocked phone. LG is very good about fixing and they have fixed mine. Also there is no permanent root for MM 6.0, so when you use kingroot that is ONLY made for up to Lollipop 5.1.1 you take a chance of bricking and there is only 1 way out , send to LG
Is there any news about this model.. I also have one bricked.. Can someone help me with this, please ?

Other than sending the device for repairs, or buying another phone: there's nothing else that could be done.

In Need Of Some Assistance With SM-G930F Is It Dead?

Hello, First time poster long time user of XDA, I some what experienced with flashing roms, recovery, kernels and modems but I ran into my first major issue.
I will start with how I obtained the phone and go from there, I think the more you know the more you could help.
I got the phone on ebay relatively cheap, its apparently google locked as he forgot his password, no biggie for me ill get around that.
He claimed he was replacing the screen and cracked the new glass while trying but not the lcd.
Anyway once I received it I turned it on and tried to see how far I could get in the initial set up.
I only got to the wifi selection screen, It would not turn on and when the button moved to the on position it would indefinitely load.
I assumed faulty rom flash.
I downloaded the latest rom from sammob and flashed to oreo, same Issue, I should point out at this point I had no data left on my sim to proceed on the phone without internet.
My friend who very experienced with the flashing seen suggested the modem.
I flashed one he suggested then no sim reception def no wifi.
ok damn.
I went to flash the oreo once again and for some messed up reason I wiped the nand only.
Well I wasnt to happy with myself to say the least.
To further ad to the pain, I can no longer access recovery or download mode to salvage this.
No button input seems to work.
It gets to the pulsing samsung logo and that its.
I even resorted to making a usb jig, It has no response to that but my spare note 2 boots to download no worries with it.
It does charge via usb, The buttons were working correctly when I was first in android at the beginning.
Does anybody have any suggestions or ideas?
Many thanks in advance, I will be following this post regularly and reply with feedback and report progress.
Cheers. r3al77

Screen died - phone still works - is there a way to fix?

Hey guys.
So today my screen just randomly died. Didn't drop the thing. Used it the one second, the other second it was just dead. Phone still works. vibration, touch, sound etc still works, but the screen will not display anything, not even booting to recovery or fastboot.
Recently installed the global ROM. I got the phone in the original Chinese ROM. This poses a problem. Ordinarily, I would have sent this thing off to Xiaomi, but I am fearing that I may have voided my warranty by unlocking the phone and also installing the global ROM. So, I would greatly appreciate input on the following 3 points
1) What troubleshooting measures can I take to try and get the screen live again?
2) I have heard that I can flash the original ROM and this might help my case for a warranty claim. Problem is - 1) I cannot use the phone's interface, this might make it difficult to navigate TWRP. Unless I can control TWRP through the PC command line? 2) I never enabled USB debugging on the flashed ROM. However, i flashed something recently through TRWP (the Global ROM region fix), so I am hoping I can still flash things through TWRP.
3) If I cannot achieve the previous two points, is it worth sending this phone back to Xiaomi. I bought the phone through Gearbest and I live in South Africa, so I imagine safe shipping will set me back anything from 50USD to 150USD.
UPDATE: I managed to boot to TWRP - using the "adb devices" command brings up my device ID. Maybe there is hope for flashing the chinese ROM if I can simply navigate TWRP through the command line.
Is there not a fastboot image of the ROM you can flash? I'd send it back in anyway, chances are they'll just replace the screen and flash it back to stick.

Yes I believe there is. But I hope I can flash the original via MiFlash.
On another note - ive been doing some reading and apparently black screening on Xiaomi phones is actually quite common. I am beggining to think my black screen might be a software problem with having moved over to the global.
If anyone has some spare time - I would appreciate a step by step guide on how to revert to the chinese ROM (i am busy downloading it). I am hoping this might fix my black screen, and if not, then atleast I can send the phone back to xiaomi with stock ROM and make a warranty repair/refund
Thanks.
mi mix 3 very fragile
black screen, same happened to me, new phone, fell down and black screen. not broken , phone still vibrate, and ringing at a call . nothing shows up, useless . I had 3 xiaomi phones before, I broke the screen but they still work.
I destroyed a note4 screen after a car pass over it ( feel from my pocket driving my motorcycle,).and still work. I Have also a note5a prime with broken screen totaly working. Then I loved MI phones.
this mix3 is a ****, a little fall down,(whit gorilla protection in the screen and with
it the cover on it , and become garbage). I will not reapair it , will repair my note5a prime.
Lisent this : if you go fishing and your are not taking well care of your phone do not buy xiaomi mi mix3
it is slippery .
If you know any solution whitout replacing the display module, will appreciate. Regards. Martin
I had the same problem, do you have any solution without replacing the display?
Regards Andreas

I broke my screen. Went to xiaomi hk and they fixed it. 860 hkd which I thought was fair.
