Question Tab S8+ (SM-X806B) acting weird - Samsung Galaxy Tab S8

So 2 days ago i made a deal for a S8 plus tablet. Second hand but as good as new. Not even a scratch. First impressions were great, model and serial numbers matching (SM-X806B). Came home happy.
Then, at 40% batery, i turned on economic mode. SOme time later i noticed a vertical stripe always on the right corner, everytime the screen moved, like a vsync problem. It seens to appear only when refresh rate goes down to 60Hz, instead of 120Hz default.
So i soft reseted and found out that, when shutting down, the tablet show some command line like a Linux distro. When booting up, it shows a debug panel beside the android/samsumg logo, with some of the hardware info. Now i'm also noticing random red flashing on all the edges of the screen, like when it's loading something.
did a factory reset, and some of the samsung aplications would not install, saying it mismatched signature... Can't update android either through the settings menu. Google apps works fine.
Finally, even after the factory reset, the dev's options were already unlocked, with some apps like IOThidenmenu on the app screen.
So, do you guys know why is this happening? Is this hardware /android version a test model? If so, is there a way to rewrite it to a customer mode?
I don't want to keep a expensive time bomb in my hands.
Thank you all

You can flash the latest full firmware and see what happens. Click the yellow How To Guide quick filter at the top of the list of threads in this section, then you'll see one of the first threads is for rooting. You don't have to root, or even unlock the bootloader, so skip anything about that. You just want to use SamFirm or Frija to download the latest firmware, and then use Odin to flash it to your tablet.

So, in the meantime, the tablet was completely off for almost 20 days due to myself sleeping while watching youtube crap and not having a proper charger. Found out that usb (common) can't jump-start it once it shuts down. Was waiting for Amazon deliver a original charger, as in here knockoffs are rampant...
About the red flashing edges: ive noticed it only happens when the tablet is upside-down from the vvertical perspective (usb up). Still dont know why, but at least i know what not to do.
About the screen tearing: gone. Dont want to know why. Leave it there.
Still cant update 99% of galaxy store related apps and cant do ota update. Funny thing is hardware diagnostic apps like antutu, geekbench, cpu-z won't precisely tell me about the hardware in it. Some would say its another soc (snap dragon 440!) While identifying the adreno 730. Others wont show the android version correctly... Some will it's rooted while others not. Crazy stuff. It's clearly is, at least, a tab s7+, even if it had a customized rom to fool people. But its not. 8gb of ram, samsung's test app and the serial number all but confirm it is a sm-806b.
So, looking more deeper into it, i found this:
from this info, it (sort) can be established that:
It from november 2021, Austria, binary category 0.
A test model. And it arrived in south america somehow.
What would you do? Sell it for 3x times the price on ebay or try to overwrite the firmware so you could update and make use of AR camera bull****?
Jokes aside, can i overwrite the firmware with a american version without bricking it? My sim cards works fine as it is now, but i suspect that even with a recent EUX, i wont be able to update galaxy store apps due to geolocalization.

Wifi not connecting.

As the title suggests, i'm having great difficulty connecting to any network (secure network at home which was working w/o problem and 2 other open networks).
It will show them "name - secured (wps available)" and upon putting in my password will remain "connecting" before staying "disconnected" or after it scans again turn to "saved - secured" and repeat this process.
I can manage to connect it via WPS however cannot get any access to the internet or it will repeat the process.
This happened after many trouble free days using a custom ROM. I'm not sure whether it started happening before or after i flashed a new rom, however nothing I do now seems to help. There doesn't seem to be any defaults to clear (looking through running applications and titanium backup), I've re-flashed different roms, kernels and modems with every combination of wipes and performed a 1-File factory firmware install on ODIN. I've read through towers of threads and haven't found an issue like this one but am getting frustrated in my limited knowledge of the android system.
Any advice is appreciated!
*edit*
I will also add that using my phone as a Wireless AP works fine.
Another update which may help diagnose whats going on.
After getting it to connect to wifi via WPS button I can use it however bandwith is quite low and it connects on these channels, and after increasing my distance from the router it disconnects however is still visible

Have you tried resetting the modem router. When I had a s2 I had a similar kind of issue that was resolved by resetting the gateway.
My wifes motorola razr also had a similar problem and after upgrading firmware, wipes I had to factory reset the gateway to resolve the issue with that device.
I have only had it happen to me once with a samsung galaxy phone but I would give that a try

I've tried unfortunately it's just peculiar to me how it will connect when close to the router but not when far (despite showing good signal), I also couldn't connect at the airport to 2 different APs either
can you get another identical phone to test with?
a non LTE sgs3 (i9300) should be good enough.

yes, i used my father's i9300 last night before bed to update his app's on wifi.
one thing that's crossed my mind is how well i've flashed the roms. as each rom i've gone to i've had my APN's in most and saved connections in some of them. is there something that isnt getting re-written or deleted when flashing or formatting? i've formatted the mounts in CWM, performed factory resets and cleared my caches in any number of ways... is there something i'm doing wrong :\
even after flashing a stock rom i still had my mobile AP's and misc. files on internal SD
have you tried any of these two fixes that work for some people

sorry, so are you saying it works fine with the i9300? no reception issues? is it on ICS?

i don't understand what you're saying here. what does APNs have to do with wifi? what do you mean APN and "saved connection" (??) "IN" some of them? what does that even mean?
it doesn't sound like your wiping process is the problem here.

yes, the i9300 works fine, no reception issues with it nor any device at home. it is on ICS. as did my previous i9300 on ICS or JB...
THIS phone (my i9305) was working fine for the past 2 weeks on L335K1s 1.1.. until flashing a few other roms
what i was saying that after performing a full wipe (and obviously clearing cache), and flashing different roms i've found that sometimes it will keep my mobile APN's as well as some still have my saved wifi connection and some don't..
by comparison, when i first got the phone on an optus firmware i had to send myself the telstra APN via their mobile setup page. when flashing the same optus firmware last night my access points were already there when on first boot as was my wifi network name "saved & secured".

Im having the EXACT same issue (i9305 LTE 2gb UK on orange), HOWEVER i can confirm i've been running a stock ROM since i got it (around 2 weeks ago) so i can confirm its not just you having the issue, and it mightnt be through modding your firmware.
I get 6ft wifi range *at best*, although the range for network discovery is normal (i can see my router anywhere in the house as normal with max strength), but it only connects when within 6ft of range. Means WiFi is pretty much useless im physically sitting on/beside the router. I've tried this at my house, my mothers, friends, and at work, including wireless B, G, N and multiple brand routers (tp-link, Virgin Superhub, BT Home hub) and i can confirm nothing has worked.
Ive tried the *#0011# turning off wifi power saving to no avail. Tried turning off notification, and keep wifi on during sleep, and disabling check for internet service. nothing makes a difference.
All that happens is that it sticks on "connecting" for ages, then disconnects, occassionally saying theres no signal strangth despite there being full strength. Means unless i forget my networks its in a constant state of trying to connect which hammers the battery, and it doesnt connect when it should in the first place.
Tried doing a factory restore 3 times which has made no difference. My phone is rooted so i can use apps like titanium backup but apart from that its stock. I now need to figure out how to un-root it (to get rid of the red ! on bootup) so i can send this POS back
if you find a solution, please post it here and i will do the same. Any help or suggestions is appreciated
Livid to think we've only had the bloody thing a couple of weeks and this happens

Not sure if this has been tried but what if you forget the network you are trying to connect to so the login info is erased for it and then re connect to it. I saw a similar thing on the weekend with a relatives phone after I made some changes on the router and forgetting the network and reconnecting solved his issue
Sent from my GT-I9305 using XDA Premium HD app

What a relief that i'm not the only one, that is exactly what was happening to mine. (All I know is mine is an early model i9305, perhaps different to a majority of the i9305T's sold here, perhaps earlier hardware?)
After testing all I could, trouble-shooting with samsung through some pretty basic stuff, and performing hard and soft resets between flashing roms, I decided to send it off for repair, suspecting a hardware fault.
My advice to you, would be to get it exchanged immediately as if it is under a month old, it will fall under "Early Life Failure" (ELF). Whilst the issue doesnt completely render the phone useless, it was a fully functioning part of the phone that stopped working out of nowhere!
To un-root download Triangle away from here:
http://galaxys3root.com/galaxy-s3-unroot/how-to-unroot-galaxy-s3-i9300/
And download your stock firmware.
Triangle away appears to require a custom kernel to reset to 0 on this phone.
When you are ready to send it away, install a custom kernel, then install the Triangle Away app.
Run this, and then turn off your phone (do not restart or go into recovery as this will reset the counter again).
Now boot straight into download mode (or the binary counter will go up), and flash your stock firmware through ODIN.
It should now be a completely stock i9305, and after performing a hard reset (with *2767*3855# in the dialer), you should now have a clean phone to send away. :good:
I'll let you know the outcome of the warranty claim and what Samsung say.
Alright chap, update time. Let me break down your post so i can answer it bit by bit.
I ran triangle away, it got rid of the red "!" showing on the top left of my phone boot screen, cheers for that!
I next grabbed the latest firmware which is I9305XXALI5_I9305EVRALI5_EVR.zip from sammobile
flashed that with mobileODIN, now back on stock firmware which I already was on, and no red "!". however when i go to settings->about device and software update, it says "there are no updates available as your device has been modified" and when you go to Settings->about device->Status, then scroll to the bottom, device status shows as "Modified". I'm gonna need to get this back to "Normal" before i send it back.
Anyways, regarding my ****uation with orange. *******************************
My contract was upgraded renewed on the 9th, I got my S3 LTE on Monday 12th (of November). On Friday the 23rd I discovered something had happened with the WiFi, and it was completely borked for no apparent reason and is now since then reduced to its 6ft range distance. spent all of Friday night and Saturday morning trying to figure it out, including rooting on Friday night to see if that helped, to no avail.
Note: between getting the phone and rooting it (AFTER i got this issue), the phone was completely stock. Now i know how stupid it was to root after discovering the issue, but sod it I've done it now, so imma have to undo it. ANYWAYS....
Saturday (the 24th) afternoon, I went to an EE / Orange retail store, where all of the employee's in the store had a try to figure out the issue, with no success. They tell me to contact Orange via the telephone for a replacement (as apparently because I ordered my handset via the telephone, i had to contact them for a replacement).
I contact Orange on the phone on Wed the 28th (by now its passed the 14 days cooling off by a couple of days) and I get through to an absolute idiot who fills the foreign call center staff stereotype perfectly.
He gets my name, phone number and handset wrong several times EACH during the call, and tells me all i'm eligible for is my phone repaired. When I tell him i'm not happy, he changes his mind and says he will "make a call" and get a new handset sent out to me, and even asked me when the following day (today) i would like to take delivery of my new phone. This call takes approx 50 minutes, 20 mins of which was waiting for someone to answer, then 10 of the remaining 30 of the actual "call" was spent on hold.
He then calls me back to tell me my iPhone has been ordered and i should have it tomorrow (today). When i pointed out i don't want an iPhone, and my phones an S3 LTE (for about the 10th time) he says "the phone line for getting a new phone has just closed at 9pm" (it was then a couple of minutes past 9) and he gave ME a number to call since HE made a f*** up of the order.
Wake up today, go to work. On my lunch break call the number, which turns out to be the insurance hotline (Orange care) The lady on the phone reads my notes and is confused, according to what the guy last night had wrote down, My phone was a Galaxy note 2, later in the story it became an S3, and then he put in a claim for me having a broken iPhone.
I re-explain everything to her, and she was very sympathetic. She told me it wasn't an insurance issue, but a fault, and I needed to speak to someone from faults. I asked her to find me a English speaking person, of which she agreed. She came back twice after putting me on hold to say she'd found someone to speak to , but they could barely speak English. On the third attempt, she found someone who "can just about speak English, I've explained everything to her, so you should be OK".
After a 5 minute wait I get put through
I get put through to a lady who is speaking in broken English sentences. She first puts me on hold while she reads my notes (insert 10 minute hold time). She says all that can be done is for it to be sent away to be repaired. I say I want a new phone, as it was within 14 days of getting the phone, and I don't want to mess about with waiting to get my phone back, I just want a new one. She says "all that's popping up on my screen is repair". I said I'd go into the Orange store and take it up with someone in person.
/end of ****uation *********************
il update you on this once i get to the Orange store, which won't be until tomorrow.
in the meantime, any ideas on how to change it so settings->About Device->Device Status back to "Normal" and not "modified"?

Sounds like you were having just as much a PITA situation as me. It surprised my friend the other day that I had to send my phone away for repair (being an iPhone user...) and surprises me too for such a premium handset. I wish more companies took a page out of apples' book on this one. I generally try and be as patient as I can with these people and show them that i have done a lot of troubleshooting myself to save time. Often it will result in being transferred to the correct person to talk to a lot quicker.
Ok I should've made it a little clearer, I found that the phone would only be unrooted if I flashed a rooted firmware with custom kernel, and after running triangle away flashing the firmware ON A PC. This is what I meant by going straight into download mode (something about the way mobile Odin installs the firmware still causes the custom binary to appear)
Samsung have however repaired my phone (according to their online job tracker) and my phone is being sent back to me! (After almost 10 days.. probably 14 before I get it back!!!!!!). I will try find out what was wrong although I'm not sure how much Samsung will tell me. I am glad that the unrooting procedure worked without trace and my warranty was honored!
Another update: used desktop Odin to flash my phone back to stock rom after previously using triangle away. Still showing as modified in Settings->About Device->Status.
gonna go into the Orange/EE store tomorrow and complain (when i say complain, i mean about the dodgy wifi issues, not complain about it showing as modified XD). Any suggestions about how to get the modified status back to normal is most appreciated.
Did you flash from stock rooted rom? I had the same issue doing that. It was fine flashing from a rooted rom with a customer kernel
yeah i did, so that could be why. im pretty new to android (been an iOS guy for the last 4 years) so still trying to figure stuff out. doesnt really help that theres not much info out there for the i9305.
What custom kernal/firmware should i use from here? im guessing you mean to flash the rom again but to a completely modded firmware of some type, then back again to the stock one yeah? I've read something about backing up your imei and elf/efi data incase stuff goes wrong but ii havent done this yet, should i do that first?
Another Update:
Went into the Orange/EE store. was messed about by a member of staff who told me i had to go home and phone orange, then arrange repair via them. Left the store pissed off and went to Burger King. Went back to the store as by this point i'd wound myself up into a frenzy about the whole situation, Demanded to see the manager, demanded HE phone orange for me there and then, and sort this sh** out.
he got a regular call centre guy who said "all the computer is saying as a solution is repair, so thats it" so i demanded we got his boss on the line.
His boss comes on and says its out of his hands and he cant do anything about it, i told him "in that case you're no use, put someone who can" i demanded the orange store manager ask the call centre manager for his boss. He also tried being a smart arse saying it was out of the 14 day return period when i called orange to say i wanted it replaced. I pointed out it was INSIDE the 14 day period i first reported it as an issue to the orange store, and it was tough sh** that they hadnt acted to fix it then.
10 mins of hold later, guy next up the chain comes on, and says hes the person who over-rides the system for returns in odd cases like this, but says he cant override it without HIS bosses permission (you see where im going with this)....
10 minutes of hold later we get HIS boss on the line, who agrees to authorise the replacement.
we get passed back down the chain all the way to the beginning person, who arranges for a new phone to be delivered to my house between 9am - 1pm tomorrow via a courier (on a sunday).
Win.
I get home, my phones been flashed back to stock rom, but is still showing modifed as mentioned before. I do another factory reset on it (i already done one before) and its now showing as "normal", so maybe the un-rooting proceedure takes 2 factory resets? as i already done 1 earlier but it was still showing as modified? Either way, thats that done. My phone is now ready to be sent back to orange tomorrow, fully un-modded as it came, and im due a replacement as I wanted.
Finally Happy, but it wasn't easy.
Just hope my next S3 LTE doesn't suffer from the same issue, as there literally seemed to be nothing that would fix it.
Hope that helps anyone who has this problem with theirs.

How's this for a joke....
I recieved my phone back yesterday! (Yay?) I read my service report and find that the handset has had the latest firmware installed (the same one I had on it) and it has been tested to Samsung's Quality Control standards. Great?
I turn it on and within 10 seconds of starting it up (getting to the "connect to wifi" screen), I have the exact same issue and phone I sent off 2 weeks ago! They didn't "repair" anything, and now i'm being pushed around to other departments because apparently no one can deal with it directly. I'm now awaiting a reply (in 5-7 Business days) as to what the next step is in this saga, it's just so frustrating that someone didn't even properly test the phone after "repairing" it.
Sure enough my new phone arrived on sunday, the guy only took away the broken phone and charger, so i scored for a free pair of headphones and the box etc heheh.
I would bet my life samsung have got your phone and went "hmmm.... wifi signal shows as full strength", then tried to connect it to a router/tethering phone that theyre sitting next to/holding in their other hand, then said "well it connects, so it works" then sent it back, without even trying it at any sort of distance. I nearly flipped my lid in the Orange/EE store when they tried to tell me "the wifi is working as its working here" so i made the girl leave the note2 she was tethering from on the counter and take 3 steps away from the counter with my phone in her hand (at which point the wifi dropped). Its like you have to demonstrate to them what the issue is.
Also, this is something completely different, but i thought i should bring this up.
Hold your phone in 1 hand by its sides, then flick the centre of the screen with the other hand. Does it feel like its vibrating inside? almost like theres springs inside? Im just asking because the phone that broken was VERY "springy" inside, almost to the point of where you could hear the vibrations inside seconds after flicking it and it felt a bit like it was rattling, whereas the replacement lte (despite being an identical handset) has much less spring to it and feels a lot more solid in comparison, it only vibrates slightly inside when flicked. Tried with my mates regular S3 i9300 which has no spring to it at all, and feels much more solid, wonder if it just with the LTE's. Seems strange to try the same thing on 2 brand new phones and them to have a completely different feel to them though

[Q] Moto X randomly dies

Ok, so I bought a brand new in box Moto X from an acquaintance. After a month or two it started randomly rebooting, and after a couple of weeks of rebooting once or more per day, it died. Wouldn't power on (not even recovery). I sent it in for repair>got it back>3 days and it died again>sent it in again>got it back>1 day and it died again>sent it in again>got replacement>2-3 months later the new phone is starting the cycle again. Every time I pull it out of my pocket, the lock button doesn't work, and it's locked up on Active Display. I hold the power button and reboot it, only to have it happen again in an hour. I am doing a factory reset now--does anyone have any idea what the problem may be? what i should avoid when setting it up again?
This phone is 100% untampered with. No root, no nothing.
Please help me out. Thanks!

That sounds like a headache.
When were both phones manufactured? What version of KK were you running? Did you upgrade software OTA, if so what did it upgrade to?
Are you saying you never downloaded any apps? never installed anything on the phone? What services did you use? (apps.. anything, what were they?) Were there any other things you noticed out of the ordinary? What were Motorola's responses the first time they replaced the phone? What are their responses now that you are having the same issues with this replacement device?
Otherwise I'd advise you let us know what modifications (apps installed, anything) you had done and continue to do, that will give a variable context to the issue, at least. Other wise we a have an issue with no variables on the actual phone. The more information you give the higher quality the responses you can receive

1) I don't know when the phones were manufactured. Can you advise me how to tell?
2) I had a number of apps on it including WhatsApp, BBM, Toggl, SwiftKey, The Weather Network, ES File Explorer, BBC, The Economist, Espresso, Google Now Launcher, Dictionary.com, TimmyMe, MyBackup Pro, eBay, Amazon, Kayak and a few others. It's still doing the same thing after a data wipe.
3) The first three times I had trouble they had me send in the phone with no quibbles. The first two times they tried to repair it (the documentation just said "replaced component, and reflashed software"), and after two failed attempts, they simply replaced it. Now they want to start the cycle over again... asking me to send it in for repair.
When they sent me the replacement it arrived with 4.4.4. The previous phone had issues with 4.4.2 and 4.4.3 both. I am still running stock 4.4.4.
Thanks for your help

Thanks, hopefully your info helps someone help you better or hopefully it can help/spark someone truly seasoned in android/moto x etc to chime in
To check your manufacture date boot into your fastboot menu, check image to verify you're there.
Then choose BP Tools and then once that menu loads choose the option for UPC/Manufacture date read out, check for the date when it appears on the screen, maybe you are on a batch that has specific issues.
I've never heard of this issue, yuk sounds terrible. Goodluck! If you do end up finding answers somewhere else can you please come back here and post the resolution?
When I hit BP Tools it just reboots the phone... I don't know what's wrong???
maybe static electricity?
or do you use any cases?
maybe wrong charger?
Multiple devices, different Android versions, Sounds like an app issue to me.
If it happens frequently, then that is good in a way... You could factory reset and don't install a single app. If it doesn't act up for a couple days ..... Install about 5 apps. Go a couple days.... Install 5 more, etc... Etc. When it starts to act up, you know it's an app you recently installed, so it'll be easier to narrow down.
A logcat could help too. Search on that for how. It would likely show what happened at the time of the reboot /shutdown.

use the volume +up button (once BP Tools is highlighted) and not the power button to select BP Tools I'm assuming that's what's happening, hmm
I would send it back to Motorola again. If the issues continue, tell them you want it replaced with something else like the 2014 Moto X.
Ok -- so the issues stopped completely over Christmas vacation, but I went back to work this morning (I work in a dusty woodworking plant) with my phone in my pocket, and bang, they were back. Every time I pulled my phone out of my pocket it had powered off, and finally it didn't want to power back on. I called Moto, and this time actually got a competent rep on the line. He blamed the issues on static electricity, and I second his opinion, because the machinery I work with tends to create some static, and the dust in my pocket may exacerbate the problem (?)
Anyway, he recommended that I plug the phone in and hold the power button for 2 minutes to drain the static. Voila! It seems to have worked.
Solved for the time being. Thanks everyone for your input.

This thread is awesome.
Also, I recommend leaving your phone on your desk/home/car when you work
Or maybe a full-body armor case or something.
Statics & electronics = bad idea. Even if you can drain it and it works, it's still hurting the components inside.
So, it's been a bit, but I just came back to this phone. I never did send it in to Moto, though it seemed to have died completely. It sat in the drawer for a couple of weeks, and now on a whim I plugged it into my computer, and it started up! I had never tried plugging it into a computer, just chargers...
BUT,
In the last 10 minutes it's been sitting here rebooting itself every 2 minutes... I guess I'll try wiping it again (It didn't do the trick last time), but this phone has serious problems.

G4 Boot Loop

I am having a boot loop issue. I have T-Mobile G4 that is NOT rooted. I bought it on release day. I too would get random reboots, particularly after the recent security update. I also noticed that the operating temperature was really high, a lot lately. I thought it was a rogue app (clean master). Anyway, I updated a few apps and installed a few watch faces. Suddenly, my phone was drained prematurely. Plugged it into a quick charge charger when all the fun begins. Early on it would boot to the home screen but would reboot a minute or two later. Then it stopped booting to home. On two occasions that I caught, it was starting up like a firmware update just installed with the "Android is starting 1 of 143 apps" type of line. After seeing that and still not getting to home, I figured I might as well factory reset it. Well I was amazed to discover that a factory reset yields the same boot loop. All I get is the LG logo.
Defeated. I go to my local TMo retailer where I bought the phone only to find out that I have to wait for delivery of a replacement( I smell refurb). I'm in Jump btw. I did notice that when the phone will boot to home screen for whatever length of time, the LED would work. The LED does not work during a boot loop. My research on this issue uncovered an alarming trend on the Internet. No solutions other than replacement. No cause has been identified either. Without proof, these are my top suspicions: Quick charge, 128G SD, apps moved to SD. My hunch is quick charge. All of my chargers are Qualcomm certified quick chargers. and I use them 95% of the time. I would hate to add LG to my list of boycotted Android vendors under Samsung.
Things I tried:
Recovery mode
Download mode
No SIM, Battery and/or SD
Swapping batteries
Safe mode (once)
This happened to me yesterday. I was listening to music through the bluetooth at the gym and it stopped playing. When I walked over to the phone it was already in a boot loop.
Reflashing does nothing nor does a factory reset. They are sending me a new one as well.
Funny thing is once it did make itself passed the boot screen to: "updating apps" This smells like an update is bricking phones. I went to the store and the agent said he couldn't find any data on a recent update but I think he wasn't looking at the right place. If there's an update bricking phones I will be livid. I'm 40 days away from a Jump upgrade and they said I can't exchange it early anyway because it "has to be in working condition." Well no ****, YOU can do the warranty replacement...give me a new phone! I too abandoned Samsung after the Lollipop Note Edge upgrade made the phone discharge in 3 hours or less and run as smooth as gravel. LG has suddenly made me sour too.
Same exact issue as you described.
Also tried everything you did. I went with TMO's replacement, and to my surprise, it was a new phone rather than a refurb.

Question Black screen of death / GrapheneOS Pixel 5a

Tl;Dr - my pixel 5a5g got the black screen of death a few months ago. Last night, I tried using the flash tool to try to flash it back to Android from GrapheneOS - so that Google would be willing to fix it maybe. Flashing seemed to fail. Unsure what to try or do next.
---------------
My Pixel has had the black screen of death for a few months now. I'm assuming it is from falling a few feet to the ground. It had a custom ROM - GrapheneOS - on it. Unless I can reflash to stock Android, it sounds like Google/ubreakifix won't look at it, and thus - no chance of repairing it for free or a smaller charge.
The other night, I tried attaching an OTG keyboard to the phone to log in to it. Since the display is black, I'm not sure it worked. I also tried several times to press where I thought the numbers for logging in would be - on my completely black screen. Somehow, I was eventually able to get my PC and Google's flash tool to recognize the phone. However, I might have messed up on some steps - because I think it might be bricked now.
I think I forgot to remove the grapheneOS key via their Web installer before trying to flash android. I used minimal abd tools to unlock the bootloader (and it still says it is unlocked)... When I tried flashing back to stock android using the android web tool, it went through the motions, but then said something like it needs to detect the phone again after flashing. And it wouldn't detect the phone again. Even if I unplugged then replugged the phone. The directions said I shouldn't/wouldn't need to press any keys on the phone for this step, but it just wasn't progressing further... So, I ended up holding the power button and volume down button - and it went into fastboot(?) again - or whatever that does.
I can repeat the steps of going thru the motions of flashing the device now, but now it gives an error saying something like it can't lock the device.
Being that the 5a screen is completely black, I have no idea what is going on - or what to do from here. I've reached out to some local repair places, but honestly, if I can't flash it myself to stock so that Google/ubreakifix would look at it, then it probably isn't worth sinking money into.... There's decent condition used ones around $120 or something out there... And ubreakifix would probably charge between $160 and $200 for screen replacement + labor - and I'm assuming that's not including a motherboard replacement - if necessary.
Ubreakifix said that they would be willing to look at it, but they can't actually do any repairs to it if it isn't running stock Android. They'd charge for the labor, and they'd temporarily use a screen to look at what it is doing/not doing... But wouldn't actually do the screen repair. I'm assuming the phone never flashed completely, but I'm hoping they can tell me if their diagnostic tools work on it - since I imagine it should work -- IF stock Android is actually installed again on it.
I've also looked into doing something like getting a displaylink adapter + display link app so that I can see the screen on the computer... But even after my multiple attempts of logging in to the phone, I can't send app downloads to the phone. Google Play store shows that the phone was "last seen" months ago... And even if I could push the app download, GrapheneOS still requires manual approval from the user to accept/finalize install of the app... Which would be pretty hard to do without seeing the screen. And obviously since I've tried flashing the phone several times last night, i have no idea what the phone is looking like. Probably app downloads are out of the question now.
Apparently you can't normally do display out of any sort with Pixel phones. The rumor I've seen on here and/or reddit is that Google got rid of it years ago, maybe so that they can sell more Chromecasts...
Does anyone have any further suggestions? I could try using scrcpy or whatever it's called, but I probably should have tried to use that before attempting to flash the phone... It's sure hard to give up on something that I spent good money on. I'd like to think there's something I haven't tried yet that I can do to save it...
You could probably try these steps:
1. Open up Device Manager on PC
2. Connect your phone
3. Hold Power + Volume Down
If you have new device in Device Manager, you can do everything with your device like flashing or try "to remove the grapheneOS key".
Edit: I'm dumb and didn't notice that part where you tried this. You should just boot into fastboot and remove that custom AVB key with fastboot erase avb_custom_key, and then reflash the phone on flash.android.com. Hope that helps!

S20FE TMobile black screen

Got up this morning to a black screen. At first power + down volume would show the Samsung boot screen, but it would never fully boot. One time it did make it to the the home screen but froze almost immediately. After that it has only showed the Samsung boot screen a few times while holding down power + down volume. I have tried tried power + down volume or up volume several times now and can never get it to show anything any more. The phone should also have power as it has been charging all day. After doing some reading I was going to flash it with Odin, but it only shows up as QUSB_BULK_CID... and Odin doesn't see it. This is after installing Samsung USB drivers v1.7.59. Is there anything else I can do?
hello colleague
Reading this post makes me think about making periodic backups.
since I also have an S20 FE 5g TMO.
I hope I have a solution to the problem.
but apparently I think it will be hardware problems.
I have investigated and there is also a publication of an s20 with the same problem.
greetings
Can you point me to the S20 with the same problem? I really hope it isn't a design issue with the hardware as I have 3 other S20FE's. All bought at the same time. The phones are only a few months past 1yr old. Would be nice if it is a software issue. Since I couldn't figure anything out with it, I dropped it off at a replace called ubreakifix by asurion. They were listed as a repair center on Samsung's website.
I got the phone back today. At first the shop said they couldn't reproduce the problem after I left it there. It was just slow to start up. Gave it back and didn't charge me anything. After I left I just started open and closing stuff. And the UI would freeze some, plus I would get System UI not responding and Process system isn't responding errors. I took it right back with the error. They were able to scan it again. This time there Samsung software said it had corrupt memory. They said the board would need to be replaced and that would cost what a new phone would cost. So, I just ordered a refurb S20FE from Back Market. I am still going to try and wipe and flash it. But, I don't know if I trust it now.
Just looked in the software update menu and noticed it updated the system on 2/7 at 12:10pm. The phone had the black screen on the morning uf 2/8. The alarm didn't go off at 6:00AM. So, it started acting up less than a day after the update. Coincidence?
