Bug!!! P20 locked after last firmware update - Huawei P20 Pro Questions & Answers

Hi guys!
Since I upgraded to the latest release of Oreo 8.1.0.120 (C432) (branded H3G) the phone keeps crashing !!!!
Virtually all of a sudden the screen is divided into 2 vertically, a completely black part and a slightly lighter one with the time indicated.
The phone can not be unlocked in any way, either with the power button or fingerprints.
He receives phone calls (the accept and reject buttons are vertical) but nothing else.
Tried to do soft reset several times (deleted cache and system reboot), 1 time also hard reset: sometimes it restarts and returns to normal, sometimes it remains exactly locked as before.
Screen resolution modes is fixed to fhd + .....
I thought it was a bug on the reactivation from a bluetooth device (the speakerphone of the car) because the first time he did it when I turned off the machine and the device was obviously connected, but instead he did it on other occasions not attributable to that.
Face recognition doesn't work too (I'm not able to recognize and save the face).
I got the phone as soon as it came out, and it never had any kind of problem .......
Called huawei support and they told me to send him for assistance, called H3G and ditto, I asked if they had news of this bug but it is the first time .....:crying::crying::crying::crying::crying::crying:

Use funkyhuaewei or if you have TWRP installed reflash stock fw that should fix

Hi! Thank you for the help but I have no TWRP and I've seen that for funkyHuawei the minimum credit is about 40€!!!!!! Is there another procedure to reinstall the firmware??????

Hard Reset not working?

Today I got my Kaiser back from repairs. I got my mainboard replaced because of connection issues. It came back with it's original 'software'.
After installing Hard-Spl (white screen edit) I successfully flashed "Dutty's Official WM6.1 5.2.19209 Release" to my Kaiser.
I wanted to Hard Reset my device using the soft-buttons and soft-reset method, but it seems to be broken (?). I managed it in the past (before flashing and repairs) but for some reason it doesn't work anymore. Soft-resets and Bootloader mode still work.
Anyone got an idea?
Thanks in advance
P.S.: In the meantime I hard-resetted my device by going to Settings => System => Clear Storage

Few Tricks, Make sure you are not plugged in USB. Make sure you are not "fat fingering it." Some people use chopsticks to be sure. And Hold it for long after the Screen goes Black.
Believe me, I've already tried the things you said.
Although I successfully mananged in the past to hard reset my phone, I checked the threads and the following vid:
How To Hard Reset Kaiser:
http://www.youtube.com/watch?v=fZPzT_L2FZQ
Usually I am the problem, but this time I can't figure out what I'm doing wrong.
Just wondering:
Which part of the Phone (ROM) is in control of the Hard Reset part? (e.g.: Bootloader, Radio Rom, Regular Rom,...)
Use "Clear Storage". It does the same thing.
Also, JM is most likely correct. It is most likely an issue of how you are pushing the buttons. Make sure you hold only ythe soft keys first, using your fingernails, then push the reset tab on the bottom & hold it. Don't just push the reset & release, but keep it held down.
Based on your previous message about your phone being haunted - mine is too btw, I think it's because the soft buttons aren't being acknowledged by the OS - which implies some REAL big problems.
I took mine back to the T-Mobile store today where I got told that it needs to be sent back to their workshops to fix it... and then got told that "mostly they just send out a new phone".
My phone is exhibiting the following symptoms.
1) Green and Red phone buttons do not work.
2) Soft buttons do not work.
3) D-Pad and wheel work intermittently.
4) (and most strange) the back-space key on the slide out keyboard does nothing, and on the virtual keyboard it flashes (to suggest that the key is being pressed) but still does nothing.
I've tried to access the bootloader, and perform a hard reset. I'm now looking for the original T-Mobile ROM to install (which was why I went into the shop), as the issue around the backspace key implies to me that the issue is in the OS not in the hardware.
Jon
Thanks already for all the input.
I've been trying all weekend in every different possible way to perform a hard reset. Fat fingering is really no possibility anymore. I've used every possible tool I had (needle-nose pliers, chopsticks, pens,...) to eliminate fat fingering.
But nothing helped. Jon (a nice guy) might have given a possibly correct diagnosis for my problem. But it wouldn't explain why I still can get into the bootloader.
Problems since receiving my phone from repairs:
Backlight changed out of itself => performed Hard Reset
Phone pad pops up and seems to start dialing => flashed new ROM
Wakes up constantly after a few seconds from standby => performed Hard Throw against the wall
As you can see, my latest problem is that the phone automatically wakes up from standby after a few seconds. The weird thing: it only does this when I put it in standby, but it doesn't wake up if it enters standby by itself.
=> NOTE: This may support the 'fat finger'-theory: the Kaiser gets some sort of keyboard input due to faulty hardware. Therefore I cannot Hard Reset my device, because of the additional faulty input.
I've used the "Clear Storage" method to perform one of my hard resets, but this has to be solved. I will be sending the phone back for yet another repair.
Thanks again for your input everyone.
Problem found?
I think I found the problem:
I just noticed that the camera button is already pushed in halfway (like when you focus the camera before you take a picture). If I push the button gently, it immediately takes a picture without focussing (it does automatically focus before taking the shot, but not on my command).
Also, when I enter the camera app, it sometimes instantly focuses. Other times I cannot focus at all.
Hard reset is still no go.
Yet another thanks for your useful help.
Maybe found the solution?
Hi Guys...
I found that by tapping the base of the phone, it "unlocks" itself, thereby making it work. It's become *S*L*O*W* as hell, and I'm really tempted to ask them to take a look at it, but right now I need all the functions, so I'm holding off.
But, give that a try and see what happens!
Jon
Thanks for still answering my question. Go community!

Last week I finally received a fully functional and working Kaiser (have been waiting for that since december...). I couldn't accept a disfunctional Kaiser coming back from repairs.
The problem did indeed seem to be the camare button that was stuck. I tried really hard to get it to unblock, but I didn't work. I must say, I didn't try your method (didn't think of it).
Still thanks a lot.
I am experiencing exact same issues on my Kaiser (Tilt), it randomly starts to type stuff in the phone application on its own and I can't do anything to stop it, I have replaced ROMs, SPLs, Radios, now using a shipped rom with shipped radio but still that problem comes up after a few days of usage and doesn't go away until I hard reset, anyone knows what I can do to fix it? it's probably out of warranty. I checked the camera button and it seems fine.

[Q] HD7 Random Locking up / Frezing but still kinda responsive

i have had my HD7 since 4/15/2011
It has worked absolutely flawlessly since then. Smooth, fast.. Just perfect.
a couple of weeks ago i flashed to my first custom rom (insintric rom) and about two days later I flashed to Next Gen rom. The phone worked pretty great for about two weeks after that then all of a sudden the phone started randomly freezing up. it would remain responsive on what it was doing. ( a contacts info i could scroll left and right ) but I would be unable to leave that screen. the display would stay on , the power button would be unresponsive and the touch buttons at the bottom would vibrate but not take me anywhere. again I could still interact with the window I had open.
this happened mostly when trying to go to a contacts page and clicking the phone number to make a call.
then the phone started locking up when receiving calls (doesn’t do it every time maybe 3 - 4 out of 10 )
if i used the power button to turn off the phone about 5 - 6 times out of 10 the screen says goodbye but never changes after that.
I went back to the original T-Mobile stock rom (very first one) and upgraded all the way thru and though it seems SLIGHTLY better still happens quite often keep in mind this phone worked flawlessly for almost a year without a single problem
here’s what I’ve tried
Master reset (about/reset phone)
Master Reset(hold keys during boot)
goldcard reflash to original tmous rom
after reflash to original too all the updates
reflash to other custom roms
formatted sd card and reinserted
Replaced SD Card
nothing seems to help
sometimes the phone will reboot but usually whatever screen the phone "locks up on" can usually still be interacted with.. Random buttons will not work sometimes I can’t get to the wifi setting. Sometimes htc hub won’t work. Sometimes it won’t go to email.. You can see it "push" on the screen but it won’t go to them. but I can go other places.
Anyone have any ideas or have had a similar problem?

Hello i had the same problem , and wi fi didnt conect properly it disconected a lot of times and didnt conect at all again i had to take off the battery to get conection again the solution was to flash the Radio_5.69.09.29a_22.50.50.21

Samsung Galaxy S3 GT-i9305 random restarts even in Safe Mode

Hi Guys,
I have this phone for many years, but suddenly the random reboots started approx 2-3 months ago, running originally KitKat 4.4.4 at this time. Before that I was rooted the phone and I supposed it could be something with that. However, flashing back & factory resets didn't help at all, clearing dalvik caches as well. What I tried up to now:
1. Upgraded/Downgraded the bootloader -- no change
2. Tried different recovery modes -- CWM & TWRP(the current one)
3. Different ROMs -- no change, the sudden restarts persist.
(4. Updated the radio -- the signal got quite better)
Three days ago I've upgraded to Lollipop 5.1.1 (the Cyanogenmod 12.1), the same story continued after a while (different applications installed).
There's one thing for sure: flashing the factories always results into a very stable phone at the beginning, installing some more applications leads to the same state -- random and frequent restarts.
I've checked the hardware -- the power button looks ok, it's definitely not the main cause b/c it reboots without touching! The CPU temp & free memory look quite good too.
Now, the current situation is as follows:
- flashed ROM (official one): 2016-03-03 Poland (T-mobile) 4.4.4 I9305XXUFOL2 I9305TPLFOL2 (seems like the most stable till now)
- installed ATK (Advanced Task Killer) -- configured to kill all applications aggressively when the screen goes off.
For me it looks like the ATK helps much, although I don't know the reason. Also, memory checked, I've executed all kind of possible tests up to the phone -- all appears as OK. Also, I don't know if it's related to the issue but I moved all possible apps installed to the SD card. The internal memory has been formatted via TWRP before the last ROM installation... Does anyone have any idea what could be the reason for the sudden restarts? It restarts even in Safe Mode, without any obvious reason and not touching the phone at all. The CPU load at the times of restart is quite low, the temperature as well. I doubt if the RAM is corrupted or maybe the NAND has some bad blocks. Are there any useful utils for tests that could be executed?
PS: I attach some log file, which I gathered once I was running the Cyanogenmod 12.1 (Lollipop). As I stated above the situation is the same when running 4.4.4 and 5.1.1. Sometimes after such a restart, it sticks in a boot-loop (if I boot manually via the GUI in recovery or download mode it will not).
Current versions:
---------------------
Android: 4.4.4
Baseband: I9305XXUFOA1
Kernel: 3.0.31-4282983/[email protected] #1
Build: KTU84P.I9305XXUFOL2
SELinux: Enforcing
Recovery: TWRP
I beg for your help on this! Cheers!
Same problem here...
Hi there
I'm having this same annoying issue with my Samsung GT-I9305. It suddenly restarts without doing absolutely nothing but looking at the screen or scrolling a text or just sending a sms/whatsapp/whatever.... I started trying to restart the phone (nah) turning it off and back on (nah) changing the battery for another one that I have here with me (nah)... After that, I extracted the SD Card and leave the phone only with internal storage (again, nothing happened but restarting randomly). I tried not installing apps such as FB, even Pebble App or just stopped sycronizing my phone with my Pebble Time via Bluetooth, but with the same and well known result: still restarting suddenly. I have noticed that when Google Play detects that there are few apps with a newer version asking to be updated, the phone restarts too! I tried deactivating this option in Google Play, just letting me to decide when and how to upgrade my apps, but It seems that it still detects the app upgrading needs and keep doing it the same way.
About a year ago, I found the same problem with my phone, but in that time it was related to the power button, it seems that it was pressed all the time and the device felt into a rebooting cycle. I check some blogs and I solved the problem cleaning the button with this electronic cleaning spray. I almost drowned my Samsung but I let it dry for a few hours. It worked fine, until now.
My cellphone is still in Android 4.3 (I9305ZHUCNB1) I don't know why I can't upgrade it to a newer version, even when I see that the 4.4 is available for this model. Right now, I'm thinking about change the cellphone and just forget the whole problem. But I'm just exploring again to see if I can find a last solution that tackles this annoying issue.
Did you manage to solve this problem??
Thanks in advance!
Unfortunately not, I had to buy a new phone. I guess the processor or other element suddenly broke, there's no other explanation to me. Also, as you see no any reasonable support in the forum.. Anyway, wish you a good luck with this.
Not so good here too...
Thank you. But unfortunately for me too... Today my phone went black screened suddenly, when booting only got to Samsung GTI9305 logo... I tried to restart through secure mode and the other one you get pressing power plus home plus volume high, and when tried to do a cache cleaning and rebooting it showed some mmcblk failed issues. So I couldn't do so much to revert this situation. I already bought a new phone, not Samsung of course. I have read that some people had the same problem as me just because they let the battery reach a very low level in one opportunity, and something in the internal memory went broke. So it was a great phone, for three years and half, but it's so bad that it fails this way unexpectedly and without any apparent reason...
Yeh... There's no much support here, especially with old flagship cellphones...

Nokia 7 Plus - Screen Freeze - Lock and Unlock to make it work

Hi Folks,
I have got a Nokia 7 plus and since the day I have bought it, I am facing a strange problem.
Every now and them the screen freezes and only way to make it work again is locking and unlocking the phone.
I can say the screen do not respond to touch because the buttons are working properly in this case.
Tried resetting the phone, installing Android P, Rolling back to O, but nothing works. the problem still persists.
Curious to know if anyone else is facing such problem or if anyone has got any solution to fix this issue?
It a hardware problem i believe. Coz even i had the same issue. I immediately sent it to service center which was luckily nearby my home. They took a video of that issue and sent it to Nokia for replacement. They approved my replacement and gave me a approval letter and requested me to visit the shop where i had purchased the phone. The shopkeeper took my old phone back along with all the accessories and approval letter and within 5 mins they gave me a new unit.(note: the service center person told me that if you have purchased the phone from a store then you have 14 days replacement guarantee in case if any issues persist post format or tests).
I have the same issue, tried all methods you mention to make it work normally without succes. I dont know if it is a touch hadware problem because it happens very ramdomly and works instantally and normally again if I lock and unlock the screen
Some days not happens, another days happens very frequent.
Another fact, every time I installs some Factory image (Android P developer preview, Android 8.1), the touch not give problem at all for aprox 2 days or more.
I'm very frustrated with this issue.

This is the Nokia 7+ quality problem, go to the after-sales service to replace the screen for free.
So i got my device replaced and for sometime, it did not give the problem but after 3 weeks, i started experiencing the same problem. New device also becomes unresponsive at times and then i have to switch off/on again to use it. I updated OS to Android P DP3 last week but issue still persists.

I think we can clearly consider this as a hardware problem in that case.
i have same problem with my Nokia 7+, I gave a chance to nokia but I'm already starting to change my mind, the bootloader can not be officially unlocked and now the problem with the touchscreen, a bit disappointed, I hope hmd solve these issues and if not, buh bye nokia.

Sadly, this is not the case here. I did a clean install of the latest developer preview, and I still experience an unresponsive system. Right after lock/unlock it works again.

Seriously ur device need a service centre
It happens to me sometimes while uninstalling an app. Device freezes and doesn't respond. After like 10-15 seconds, it uninstalls the app and start responding.

I have similar problem.
When I want to clear data for the chrome through the settings, device goes mad, most of the time freeze and its difficult to restart it.
I thought they fixed with august security patch, but no.

Yes, it happens to me as well. Let say Chrome has 200mb cache and if I click on Clear Cache, device freezes.
I used to face this problem quite frequently, but I haven't seen it in quite a while. For this reason, I'm pretty sure it was a software related issue and not a hardware one, as a hardware problem would be unlikely to go away, but a software one could be fixed with updates.
It started to happen on ly device today. I have the august security patch and my model is ta 1055 so i don't think the problem is solved yet
Cleared chrome cache. Device freeze for 15 minutes and rebooted. On Pie dev 4
There are so many seemingly random issues with this phone, I can safely say that I hate it. I never know if it's going to take a call (unresponsive soft button), or if the person on the other end will be able to hear me (mic just randomly stops working at least once a week). Freezes a few times every day. Won't allow push email notifications after (or during) sleep, have to reboot. The list goes on......
Going to turn in my device for repairs. It's taken Nokia long enough to come up with a software solution. On the Nokia forums there are several people who were helped with a touch panel repair.
Sent from my Nokia 7 plus using Tapatalk
Already sent back the device for repairs twice, each time they sent it back with just a reinstall of an older Android version... claiming it would be fixed.
In Europe, there's no Nokia repair, so another party is taking care of the repairs. It seems like they are not really aware of the ongoing bugs/problems of the device, which makes it extremely difficult to get them to actually repair the device properly.
First time they even told me they "replaced defective hardware", when in fact the hardware was not touched at all.
I managed to record the issue with another device, and showed it to the vendor.
Now they're offering me a refund. It looks like this is the best option I can get from them.
Really sad though. I was hoping for them to just fix it. Apart from this problem, it is a really good device. There's not really a good alternative in the same price range.

Im having trouble unlocking my device, I tried the finger touch to unlock but it did not unlock and the phone is unresponsive even on pressing the power button. I tried to force restart by pressing and holding the powerup button and power nutton simultaneously but still no result. Also I could see a red led light at the lefthand side of speaker on top.
Note: The device was fully charged.
can someone help me with this Issue please

Xiaomi MI A2 turns off when unplugging

Hi.
Today appeared some problems with my A2. When I woke up and unlocked phone it turned off. Yesterday everything worked perfectly fine. I tried like 20 times, everytime the same scenario- turns on, but when I type PIN, home screen is loading, and phone goes down. It may look like bootloop, but its not typical, cuz it goes farther than just booting screen. So I tried to fix, wiped phone, set lang. to Polish, and it dumps again, but I've read somewhere, that it might be language issue, so I wiped it once more and set English. It seemed to be working, but then I unplugged it from my PC (charging only) and it turned off immediately. Worth mentioning is fact, that battery is 92%. What may cause this? Is this some soft problem? Or more like battery issue?
Update: Phone works unplugged, but only on lock screen. Turns down when I unlock.

Hello, I have the same problem. I now have to carry an external battery with me, because plugging it in is the only thing that wakes up my phone. If I don't have a charger, then I have to hold power for 30; seconds to force reset. It's really annoying, causing me to miss calls and alarms. Anyone know of any fixes? Thanks
Hey,
I am facing the exact same problem. Though I had an additional problem. My phone didn't charge when I plugged it in until I restarted it. Factory resedidn't help either.
In both your cases the problem is your wifi even if you dont understand it ...
if you can unlock your phone quickly and toggle off wifi the phone wont reboot or loop
your persist partition is damaged from changing between pie and android 10 ..
look around for a flashable zip to repair your persist ( it does it exist )
or take the long root and use miflash to flash persist by modifying certain files in stock fastboot rom folder
but next time explain your problem better
--- what did you do -- change version ( update or downgrade ) -- did you root -- do you have twrp -- what version of android-- did you return to stock from custom or vice versa --- etc etc etc
