RN7PRO hold while sim-card is disconnect. - Xiaomi Redmi Note 7 Pro Questions & Answers

Greetings, i have a problem with my xiaomi redmi note 7 pro. when my phone lost signal from sim-card -> display is became dark (blocked like u press power button once) a then u need to enter password or use fingerprint. sometimes (in the undergrounds or elevators) it can happen many times. during 5-10 minutes. and i cant use my phone. (mb its look like ur sim-card is Pull-out ir disconnected)
first of all i noted that when u turn off fingerprint and password/cyfral code -> this problem doesn't appear
2nd one - CatLog is clear (or i think so, because i can't find anything suspiciously/strange.
also i have another bug/problem: sometimes volume up/down buttons can't open a volume window (where u can change volume for notifications, multimedia and alarm) its look like that they doesn't work. but if i listen music> then press power button to hold my phone and then press volume up/down - volume was change.
what i have done:
many times try clear/factory reset
try to use different firmware ( china stable. India. custom Ми-рум (mi-room) xiaomi.eu and some others.
try to find solution in the forums/internet - the only solution that i found (i see some posts with the same problem as i have) is to buy a new phone.
The only one where its ok is PixelExperience_violet-10.0-20190922-1042-BETA firmware. But i want to use something like india.
i rly like my redmi note 7 pro. but i can't use it normaly. pls help me!)
if u need any info about my phone > pls tell me
now i have PixelExperience_violet-10.0-20190922-1042-BETA firmware.
sorry for my bad eng.

did you tried miflashtool and flashed fastboot rom.
try clear data and lock to lock bootloader once.
you can easily unlock after that but i recommend to give a try by testing with bootloader locked.
if it doesn't work, visit mi service center, they will have to repair it if in warranty.
here's the link to latest official stable fastboot rom
http://bigota.d.miui.com/V10.3.13.0.PFHINXM/violet_in_global_images_V10.3.13.0.PFHINXM_20190812.0000.00_9.0_in_842105c600.tgz

HELP: Touchpad/screen doesn't respond, can't enter bootmode/security code or PIN code

First of, I have a problem getting into the bootloader as I've said in my post: forum . xda-developers . com / showthread.php?t=759279
I've been using Kostas244's ROM -> www . forum . xda-developers . com / showthread.php?t=554071 for a few months now, no problems until now.
What happened: The touchscreen began to not respond to my input, slowly and gradually for a few days. I clicked on a few things, something else was triggered. So I figured I only had to reboot the phone. Now I can't get even use my phone.
My phone activies: Calls, SMS, Alarm, Play Solitaire, Taking Photos. That's about it. Nothing else.
Now I can't seem to enter the bootloader (Camera Hold + Power) during startup, can't get into the system cause the slider reacts just once and then it hungs up. Freezes for a while, then after I shut down the screen and turn it on again it simply does not respond at all.
First time I could enter my security code, but then I couldn't enter my PIN code so I took out my SIM CARD - then I couldn't enter my security code and nothing seems to be working.
Right now my phone ask me to enter a code due to "several bad atempts to get into the phone" and I could only press q (whatever I would input, it simply gave me a q and then nothing) and that doesn't do me any good.
Just a few minutes ago I tried forum . xda-developers . com / showthread.php?t=636170&highlight=bricked+my+cruise&page=2 on the thread ( forum xda-developers com / showthread.php?t=636170&highlight=bricked+my+cruise&page=2 ) who seemed to have a similiar problem as mine - the touchscreen isn't working.
But I don't have Windows XP (if that's the case it's not working) and the guides seems to point that it has to be in RGB mode (bootloader) and that is not working either.
Does anyone have any ideas or solutions I could try? This just happened out of the blue, I hadn't done anything with the phone for a whole day and it just began acting like this. No damage to the phone has been made or anything out of the ordinary. So it sounds like a software problem, but I can't seem to get past it.
I use Linux 64 and Windows 7 64 if there's solution to connect to the device on either Operating Systems.
Thanks anyway.
To enter the bootloader screen press the camera button an the reset button at the bottom of your phone 'the little hole next to the usb'.
You could try hard reset press and hold both bottom buttons and reset 'you will lose your contacts sms ect' so back up using pimbackup.
If your digitizer is not working 'doesn't respond to touch' try sync your phone and install mymobiler/,then you can browse you phone and backup to sd card before hard reset.
Already tried that, as I included in my previous post about getting access to the bootloader. I can't get into the bootloader with Camera Hold + Reset. Nothing happens, it's as if the buttons don't respond correctly.
Hold down both "bottom buttons"? You mean GPS and IE buttons? Tried that too. Tried a few others. And I'm certain this worked before. Like I said in my post, nothing has happened to the phone recently - it just started acting this way. So I'm guessing it's more a software problem than a hardware problem. Since I have HARD SPL and a homecooked OS the chances of it being that is a probability.
I have nothing that needs to be backed up, so I don't need to do anything about that.
Hi
I have same problem. Screen doesn't react (only if press hard), and i can't enter bootloader and make HR.
Also, I had same problem 2 month ago. But I managed to revive it - made a lot of try of HR and one of them was successful. but now it is dead again and I don't know what to do...

[Q] Touch Pro GSM not booting!

My Touch Pro randomly stopped booting, I had it charging and then the screen refused to come back on no matter how many times I pressed the power button.
So I took out the battery and after I put it back in it started turning on without me pressing the power button and it stayed on the boot screen for a long time and then went to a black screen with the message:
The device is unable to boot because either you have turned off the device incorrectly or tried to install an application from untrusted source, Press SEND to reset your device or press any other button to cancel, This operation will delete all your personal data and restore the device to its factory default settings.

Click to collapse
I tried pressing send and every other button but nothing happens. Even tried hard resetting it but nothing happens! The message just stays on the screen till the battery dies.
Does anyone know how I can get it working again?
Btw when I press volume down and the reset button I get the tri colour SPL screen, if that is relevant
Are you positive this a GSM TP? Also, you can provide the type of device for others to see if they have a similar device and perhaps they may be able to shed some light as to what may be the problem. Check your device, behind the battery compartment you'll see a couple of bar codes. Look for one called IMEI and just above it you should see RAPH###, where # equals any number between 0-9. If you have a GSM device, have you attempted to flash anything yet? I'd start with task29 and then flash either a stock ROM or if you already have HSPL'd your phone, then use a custom ROM of choice. If you find out that you have anything else besides a GSM device, you might be better off waiting on someone else to answer.

I have the same question, did it work? What does "Unlock" mean: That you can use the phone with SIM-cards of different companies?
Thanks,
Chris

[Completed] Lenovo a5000 problem(SOLVED)

Hello everyone, I have just recently bought this Lenovo A5000, everything was perfect until i did a mistake today, just an hour ago. I will list step by step how i encountered the problem below.
1. I did some search on the net about hidden code or secret code for service menu(for lenovo)
2. I found some then i tried this code ####999# then all of sudden the screen changed to multiple [email protected] testing followed by microphone test, then camera test then some other test. It keeps repeating and does not stop.
3.I tried to press whatever key is available along with home menu or multitasking hot key but no avail. It keeps repeating and repeating, Pressing on/off power button also not working.
4. The only things that work is, i was able to scroll down for hidden menu as we do on all android phone. I can go to settings but only settings display etc. I tried to search for the running service test on running programs under the apps menu but nothing. I also tried to press power off/on button here but no avail.(please take note thatthe service test still running at the background during this time).
5.Finally when i tried to close any running systems apps i managed to get into dialling menu. but again i just leave it here because the service test does not seems to work here.
6. Lastly when i look at my phone, it was already black in screen that i believe it was in sleep mode but when i press any button this phone doesnt awake. tried to press the power on/off longer but no avail. unfortunately i cant pull of the battery because it was not removable.
Hopefully anyone of you can suggest me how i can revert it back to normal. Really this is unexpected. I ONLY pressed ####999# and voila [email protected] test started. I appreciate much your help guys. Thanks
NOTE;
I dont know where i get the idea but, as i said above, the phone goes to sleep with no response. What i did a few minutes ago ,
1.Press the power on/off button and keep pressing the volume up several times followed with volume down then release.
Then Lenovo logo comes up, then VOILA! my phone was normal again.
Anyway i will always give a credit to XDA forum for many valuable tips and knowledge that i learned before. Thanks

Hello,
My wife's Sony Xperia XZ2 Compact with model number H8324 has an issue with booting or maybe the launcher getting stuck in a loop after getting to the lock screen for a split second.
The phone seems to boot like normal and gets to the lock screen, we are even able to punch in one or two digits of the 4 digit pass code. Then it goes into a loop of the notification bar and back button flickering. From then on the phone is not responding except for the power button which brings up the normal "Turn off, Reboot, and Lockdown" menu. The issue just started out of nowhere yesterday morning and we haven't been able to fix it yet. We haven't done any rooting or custom rom flashing, it's running the official Sony software but it's out of warranty.
Here's a video showing the issue. The video shows the whole boot process but the link takes you to the last part after the logos.
We would love to get some files off it so if there is a way anyone can help us with that we'd prefer it over a hard reset.
Things we've already tried
Turning the phone off and on again
Unlocking the phone in the split second the lock screen works, this is just too short to swipe up and then put in four digits.
Rebooting the phone
Booting while charging
Booting into safe mode (this has the same issue)
Connecting the phone with USB to a pc, the phone is recognized by Windows, but it doesn't share it's filesystem with Windows.
Connecting the ADB to it, alas usb debugging is not yet enabled on the phone
Trying to get into recovery mode, we haven't been able to get into the recovery menu. Googling seems to indicate it might be holding volume up + power button when the phone is off but then it doesn't seem to do anything at all.
We're currently trying to run out the battery of the phone to see if that will resolve the issue on it's own.
If anyone has any idea, we would love to hear it.

I think u just need to reinstall rom file with newflasher and stock rom , did u tried it ? with newflasher newest version , u still can keep the personal files and flash stock rom for the phone , then i think this phone will run normal again
If u dont know how to do that , reply comment here , but u should turn off the phone to keep battery well , if u can't turn off the phone , try to press and hold volume up button + power button within 5 sec , phone will vibrate 3 times and totally off
Is there a way to get a stock recovery if somehow the recovery has been deleted?
