Question How to fix reboot error - Redmi 9 Power / 9T

Hello everyone! I am currently experiencing an error wherein if I reboot my device, sometimes it won't reboot. I have to use a rubber band method (wherein you use a rubber and a q-tip (the one being use to clean ears) for the power button to be pressed down for a long period of time and another rubber band for the volume down). I hope this is only an issue in the software and not in the hardware. I just want to know who also experience this one, and how did you solve it. Thank you!

Lost Button & Keyboard Functionality

Started experiencing a strange issue with my tilt today..
When I soft reset it loads the Today screen, and then attempts to search for the contact 'wszx' (these keys are located next to each other). After this I can navigate the phone just fine using the touch screen, but the only buttons that work are the directional and center buttons located on the front of the phone, and the arrow keys on the keyboard. I cannot type at all using the keyboard, and pressing any of the other buttons does nothing (except the directional/center/Power). I also cannot Hard reset because the two soft-keys do absolutely nothing. I've hard reset in the past but it no longer works.
So am I SOL? I think I've tried everything.. and now I have a custom rom, etc on the phone and I have no way of getting it back to factory rom without the ability to hard reset.
Thanks for any help.

Sounds like a hardware issue or simply a bad flash. Have you attempted to reflash the rom? Which rom are you using?
Well...
It wasn't working again this morning, but suddenly - out of nowhere - began to work properly. I'm stumped. If I ever figure out the exact issue I'll be sure to post back.
Thanks
Greetings,
I have same problem on my tytn...
Sometimes it suddenly starts working fine, but shortly it breaks again.
I have tried hard-reseting while it was working, but didnt help.
I think the problem appeared after charging my phone with a motorola v3 charger, so maybe it damaged my phone with over-voltage or something...
Anyway, if someone can suggest something i would be very grateful!
Hi I have exactly the same symptoms with my HTC Tytn II...when you power it on it starts typing letters (in my case CEDF). If the recording button is active it will start recording too. This happened suddenly and I haven't used any other charging apart from the usb and wall socket charger supplied with it.
All buttons (except front center key) and keyboard do not work. Any suggestions would be appreciated very much. This phone is only 8 months old.
Hi,
my Kaiser with dutty's WM6.1WWE ROM did the same this morning Yes I disabled the button 6 and stopped the voice recordings but all the hardware keys but few in the center of the keyboard are not responding. So I cant make or receive calls without taking the stylus out and touching the screen soft buttons andd that's pin in the ... while I am driving. I am using this ROM for almost a year now and I am extremely hapy (up to now) with its performance. When it all happened there were no activities on the phone - I woke up from a SMS notification (Yes I did receive an SMS from my bank) followed by repeting Voice Recordings. Any help will be highly appresiated! Thanks in advance!
keyboard problem
I am experiencing a similar problem with my stock tilt my keyboard does work however none of the text appears on the screen. I have tried hard reset and everything else I could think of, short of a clear storage reload. I would appreciate any help or suggestions from some of you more experienced users.
Bisonwill
anyone ever figure this problem out? im having the same thing happen now.
Same here
I've had it for a couple of weeks now.
I'm running WM6.1 from HTC (rom ver.3.29.422.1 from 2009-01-12) so nothing fancy here.
I even ordered and replaced the D-Pad and I replaced the keyboard (just the sticky part though). I totaly dismantled the phone and didn't find any issues with the cables.
Any ideas would be highly appreciated
Join the club!
This is crazy. My problem is exactly the same. I re-romed to the latest phoenix and it did not change a thing.
Help!
help....
any body here found a solution for the keypad/keyboard yet??? i have the same problem as you guys... any idea, thanks so much...
i have the same problem And there is something else. My Kaiser wakes up every 2 minutes - it's killing the battery. It works only for 6 hours now
Help
bump!!!
No more people with this issue or any solutions?
Pls! Help
ive joined the gang!
I decided to flash my cooked rom ive been working on.
i hadnt changed much in the kitchen and i think the flash has went badly.
it starts booting windows and where it should state "calibrate screen" it goes white and hangs there, buttons seem to respond by lighting up when pressed.
Now when i try to get it into bootloader or even hard reset it just doesnt work.
it just restarts the phone.
before this happened the backspace key hasnt been working for ages.
anybody got any ideas??
(lucky for me i have a backup kaiser!)
I'm having the same problem. Automatic wakeup, applications starting automatically, can't use keyboard, have to to use screen to use phone etc. I've hardreset using the clear storage method, reflashed a couple of times, but nothing helped. So here I am joining the club
If it's not a hardware issue, then try to flash another radio, many of the custom ROMs here doesn't include a radio, so if it's caused by a wrong radio, flash a new ROM without a radio doesn't help.
Check the Sticky for 'how to' if not aware.
PS: Check here for something need to know..
The question is.... how do I flash the device if I cant get it to go to boot loader and the OS wont boot properly !?
I think its an official Brick!
the really odd thing I've discovered is sometimes the OS leaves the loading screen on, and when it does if I press the FN and folder key, I get explorer up but its not responding... I haven't tried inserting a memory card yet to see if I can access that.

Try this:
1. Take out the battery from the phone.
2. Take out SIM card and SD card.
3. Press in and hold the CAMERA button.
4. Plugin to your computer using the USB cable, while keep holding press in the CAMERA button.
See does it enter the BOOTLOADER mode.
Once entered the BOOTLOADER mode, you can flash a new radio or rom right from there, in your regular way of running KaiserCustomRUU.exe.(Since you already have a HardSPL flashed on, otherwise a HardSPL is needed to flash first.)
Good luck.
Edit: If the power button and the camera button is still working, you can use the regular way of entering BOOTLOADER mode, and flash from bootloader mode or flash from SD card.

To enter in bootloader mode:
Simply Switch off your phone. Press and hold camera button and also press and hold the power button..You can remove ur finger from power button when phone is switched on but keep holding camera button until u come to bootloader …Now attach the usb to ur computer and do the flashing you normally do.

Thx for your suggestion:
I tried removing battery as sim and sd were already removed due to previous attempts in fixing!
so:
i removed battery (did not put back in), plugged in while holding camera
got nothing, so held power button at same time, the green light came on, then went off, and came back on again. but no bootloader.
i tried same procedure with battery in, and all i get is the OS loading up, no bootloader no matter how long i hold the buttons.
is there any other alternative method to get into bootloader (possibly involving other button presses)?
or any other ideas.
Really want to fix this as it was my "experimental" phone for cooking roms with.
Thanks again.
Suspect you have some hardware issue with the camera button. Can you ever take a photo with it?
Edit: Did you read through every post onthis thread:
MTTY (How to fix a bad ROM flash!)
If you tried that and still no luck, you can post your questions there. There are masters will keep an eye on that thread. And generally they only have time to look into their 'subscribed' threads, chances are they will not look into here.
Edit: Maybe the procedure I told is wrong, since I call from memory, check this:
dwny said:
If you have a bad flash....that's no reason to worry.
I haven't had to use MTTY to recover.
In most cases, if there's no issues with the Rom itself...you can pop out the battery and re-flash the same ROM from BootLoader Mode. This will also work if for some reason your computer crashes or loses power & restart during the FLASH.
If the Rom has issues.....the flash will not complete and the device will be stuck in BootLoader Mode. At this point,you must FLASH a FACTORY ROM!!
Pop the battery off 1st, power up the device, device will power up in BootLoader Mode, connect to pc & FLASH your devices FACTORY ROM. This will restore your device back to it's original out the box settings.
The above only works if the device has been put through the Hard SPL or SuperCID process.
I personally have never tried to flash a cooked ROM without unlocking any of my devices. From what I've read what others have experienced...the flash would just fail and they're stuck in BootLoader Mode.
Myself ... I've experienced bad flashes, bad cooked roms that I've cooked, lost power to a pc & had my pc crash during a flash. Listed above is how I've recovered. There is life after Bootloader Mode.
The only time you have to worry is if your device does not power up at all
As a public chef...it's your responsibility to set the parameters of your ROM! Meaning, Radio, HardSPL, program conflicts, etc.
You are not ultimately responsible if someone bricks their phone but if they pushed the issue, you could be hit with some form of liabilty because you failed on providing a simple Disclaimer that sets the expectation.
I hope I've been helpful.....

Edit again:
And try like:
Plug in USB first, and thenn press & hold Camera, Power button etc.
I remember once I read there is a way to enter bootloader without battery, just can not find the original again.

Some keys water damaged, stuck at recovery screen.

I got some water on my G1 (possibly crept in through the slide mechanism) and I have this (unique) problem.
After the water damage the phone did continue working for a few hours before it became unstable and just hung. The "home" key became intermittently unresponsive.
Now, after some time it has gotten into an infinite loop to "recovery mode" screen when rebooting, Alt+L gets me the prompt but Home+power does not reboot, popping the battery brings me back to this screen after the bootup.
Now if we assume that home button is stuck in "on" state this would result in this loop (that is my guess).
I have already attempted reflashing with cupcake (completes successfully and prompt for reboot but I end up again at the recovery screen). I tried getting to RC29 (to ultimately move to Haykuro) with the steps elsewhere in this forum (and many other places on the net) but I cannot get to the boot loader always the recovery screen (camera + power button).
Also attempted wipe several times, the loop persists.
I dont know if the camera button is working, so its possible the the key combo is not getting registered for my bootloader attempt.
Any help on possible things to do is appreciated.
Going to t-mobile is not an option, my friend brought it back from the US and I unlocked it with the intention of development on that platform. I cannot send it back to the US even though it is under warranty, just don't think they'll entertain water-damage.
Hey, I have this same prob. I bought a phone that had been dropped in water for about $50 thinking that since it did get to the T-mobile g1 screen i would be able to get to the recovery utility ( and recover). I could get to the utility but no amount of wiping or flashing worked. I also tried flashing every ota official rom i could get my hands on (since this phone didnt have root). But nothing worked.
At one point i found the official HTC Dream repair manual and posted it in the Dev forum, but who knows if its still there or much like this post, has been moved. Inside the repair manual pdf there is a link that will take you to the HTC RMA III login page. If you can get a user/pass you can prob log in and find the diagnosic prog HTC uses to troubleshoot. I have searched high and low for one of the user/pass but only found a couple that had already been closed. So maybe you could try to find a user/pass, get the diagnostic prog, make a G1/Dream gold card sd, fix your phone and help the whole forum. I dont think anyone has a copy of the diagnostic yet, or at least i havent seen it.
Let me know if you are able to find a work around. I have already completely taken the phone apart to use as spare parts, but I can always reassemble!
Went through the service manual, I tried to do a soft reset (never got to the prompt). Next, I attempted hard reset (home + back + power) and I reach the prompt that says "press send to start factory reset", but nothing happens when I press the "call" button (assuming "send" is same as "call").
I will attempt to look through the net a bit more and if nothing comes up I am thinking of opening up the phone and see if I can do something to the buttons in case they are internally jammed.
Thanks for your help though!
I need help with this as well!

I have this same problem!
Is there a way we can remove Recovery mode
or disable the home key somehow?
on a water damaged phone you have ONE and ONLY ONE choice. you have to take the phone apart.
first make sure to get the service manual and it will show you how to take the phone apart properly, then you'll need a large bowl of rubbung alcohol(or some other volatile solvent)
take each piece of the phone apart and dip in the alcohol for several seconds completely submerging it, then take 10-15 minutes SCRUBBING the piece from every possible angle with a toothbrush. when you have finished each piece set on a clean towel or dry rag. repeat for all pieces of the phone.
then take a hair dryer and set it to low and dry the pieces of the phone for about an hour(or you can let sit for a day) and be sure to flip the pieces over halfway to ensure full drying. i have used this approach on many phones(one of which being a phone i found at the bottom of a lake). i am not promising that this will fix your phone as you probably shorted out a few circuits when you continued to use the phone, but it will help as long as nothing has short circuited
Same problem..
I'm also having the same problem... Any Solution ??
Hope is always an option. Testing is a SOLUTION!!!
I have the same problem with the home key being stuck after humidity entered my phone. Which boots me straight to recovery mode. I have managed to recover my phone with the following steps:
YOU MUST HAVE ADB AND FASTBOOT INSTALLED IN YOUR PC!!!
1) If your phone has the home button stuck, you can't update or confirm anything with the Cyanogen Recovery! Because you need the Home button to confirm. So you must revert your Recovery back to JF's Recovery to use the recovery properly in this case.
2) I have tried for weeks to make the system bypass the recovery and have succeeded. YOU MUST REBOOT YOUR PHONE FROM RECOVERY TO BOOTLOADER. So use ADB to reboot in to Bootloader mode ( adb shell reboot bootloader ). Now that your in Bootloader mode, use the FASTBOOT commands ( fastboot reboot ) and voila, it bypasses the recovery.Make a script on your Winbows or Linux to make it as easy as one click!
Before you disassemble try this.
Take off the back and remove the battery. Take out the sdcard. Put the phone, all opened up, in a ziplock bag full of uncooked rice. Leave it in there for 24 hours. Put it back together and 99 times out of 100 this will fix your problem. The rice is dry, like really dry and will suck the moisture right out of there. It is also dirt cheap.
Good luck.
Thanks, But Unfortunately my message got noticed a bit too late
My phone is working fine since the last month ..
@RichiDaze
Unfortunately m my phone was unrooted , without terminal in the stock recovery console, so i could not use ADB...
@Billquinn1
Would have helped if moisture had not corroded my connectors....
But Thanks for your replies...Hope it helps people having similar problems ..
What i ended up doing was taking a safety pin and started scraping(gently) the non shiny parts of the connector ( daughter board to main board) .
I think it was previously shorted near that area , so by scraping removed the shorted metal joints ..
The Recovery problem did not reoccur since then

Power Button Problem

Recently I've been having issues with my power button. When I attempt to press and hold it to bring up the "Power off," "Reboot phone," etc. menu, it immediately just shuts off the screen. It isn't recognizing the long-press action. Pulling the battery is almost always the only option I have to shut down the phone. Very frustrating. Anyone have a similar issue or suggestions on how to remedy the situation? Thanks.
Well if you're trying to reboot or go to recovery/fastboot you can download quick boot from the market. Not sure how to fix your shut off screen problem though.
Yeah, I've been a Quick Boot user for quite some time. It's actually shutting down the phone that I'm having a problem with. I just can't figure out why it won't recognize my long-press anymore. It just immediately turns off the screen. Very frustrating.
I have the same problem
I tried with hard reset and different original rom but the problem persists, I think it's a hardware problem.
there's a post around that describes how to clean the power button which usually fixes it. will try to find it.

EDIT: I was having to use a Gscript to power off/reboot the phone.
Leave "su" checked and make a gscript. In it put:
Code:
reboot -p
for shutdown
don't forget the carriage return at the end.
I've been having the same problem for the past couple of days. The most annoying thing is that unlocking the phone can take several attempts.
I finally had time to try to clean the button. I took the back off and took a small brush and stuck a few bristles down the side of the power button and wiggled them around in an attempt to clean around it, then blew around the button with some air. I used an air compressor but a can of compressed air should work the same. This was 5 minutes ago and, so far, it seems to have fixed my power button problem. Hopefully it was just dirty instead of faulty.

Where exactly did you stick the brush? I just got this problem :I
I realised this issue when I started using the desire rom port by Paul. I've since then switched to the Froyo build and don't encounter this anymore. Don't know if it was just a coincidence.
I've tried cleaning with a brush and compressed air, but the problem still persists. Grrr...

I took the back off and just stuck a few bristles of the brush down the button hole. If this helps you visualize it, the phone was vertical and so was the brush. The bristles went straight down beside the power button and I wiggled it around a little. I tried to get all four sides of the button, but can't remember if I was successful. I don't know if the brush actually did anything, but it's been working better after brushing and blowing it out.
I have this problem randomly... My way is to hold the power button down the whole time while pushing the shutdown button and the okay when the prompt appears!
I seem to have finally fixed my power button. Basically I just took the battery cover off and then gently pried back the plastic power button toward the rear of the phone until I could see underneath it. Then I carefully shoved a safety pin between the plastic button and the actual electronics beneath it and lightly wiggled it around a bit. I repeated this several times, testing the functionality of the button in between attempts, and eventually got it back to proper working condition. If you're brave enough to attempt this, it might work for you too.

Phone keeps randomly rebooting into a loop

I have my Galaxy Exhibit (II) 4G for about a year and two weeks now. Warranty period is just over. I used Stock ROM in the beginning and have been using CM10(.1) roms for about 10 months.
Yesterday early night I noticed my battery suddenly diminished about 60% in 15 mins. Then I had it in the charger later, and I think I let it fall one time, like that happens sometimes. Since then my phone has been randomly rebooting and then looping either the battery sign or the Samsung sign.
Usually I can get it to boot up again with holding the power button, but sometimes I just keep pressing everything until something happens.
I can get into recovery. I tried wiping everything. I have tried deleting battery stats. I have tried other (non-oc) ROMs.
NOTE that sometimes it happens in recovery mode too, usually right as it is getting into it, so it might be totally non software related.
Do you guys think my phone is broken? Or is it worth trying to buy a new battery?
Turns out the phone thinks its on/off button sometimes is pressed, so it keeps rebooting. If I press it a couple times it's over. But then then next time there's always like a 50% chance that it gets stuck again...
Did you solve your problem because am facing the same problem. I can't even make it far enough to boot into recovery

I'm stuck in the same problem, first I thought it was a physical problem but I had to get technical assistance of an expert and he confirms its rom problem. he's going to install stock again via some freaking hardware because with my pc I couldn't. Any suggestions?
Enviado desde mi GT-I9100 mediante Tapatalk
Defintly this guy couldn´t fix it, he reinstall the previous t-mobile original firmware and nothing happens, still rebooting. Another technician check it and told me he must replace a bootloader IC, I hope it works.
Now the "new technician" couldn´t fix the phone. He told my wife that previous Rom (cyanogenmod unofficial)"must have a virus and it infected the boot". I keep thinking is a hardware malfunction. Any suggestions?
If you got the ROM from xda I doubt it had a virus. Have you tried Odin back to stock yet. If not try that first.
Sent from my SGH-T679 using xda app-developers app
I dubted too, the problem is it can´t boot. I have the samsung logo, then it apears the Exhibit logo and shuts down, it keeps like that again and again. I managed to get download mode but the same, 3 sec after it shuts down so i can´t install anything.
Then ya i would have to agree that the device is defective.

I had the same problem and i use to solve it by hitting the phone from the back and after i let it fall accidently it back to normal
I have the SAME problem!!!
ok so, my phone was awesome but since this is vacation time I decided to try a new rom, It was fine but then it started rebooting all the time. HOWEVER, I was able to try other roms after several attempts and think it's related to the calibration of the power button. It tries to stay awake but when I try and press the power button, that's when the problems start. Does anybody know of a way to calibrate the power button? I think that would be the solution, in case that's even possible. If not I'll have to buy a dumbphone for I don't have the money to spare on a new phone just now...
I had something similar happen this weekend. This may not apply to everyone, but I found that after pressing the power button over the course of two years the thin plastic "arms" that hold the power button inside the case have become stretched and weakened. Went back to stock to eliminate every conceivable variable. It would continue to reboot even without touching it, with or without a case. Essentially, the power button is resting against the motherboard's power module, or rather stuck and wreaking random havoc.
I fixed it and haven't had a reboot this week by using tweezers and squeezing the posts that hold the power button arms in place tightly against the outer shell. The objective is to create as much resistance as possible and have the power button spring away from the mobo. The power button has rubber pads that, when pressed, pushes against the mobo power module, so to create more distance I filed down the pads a few mm's. If it happens again I will resolder the points and remap the keys, until then I went ahead and cleaned the solder points with a q-tip and rubbing alcohol.
Removing the outer shell takes some time to break the glue apart without damaging anything, so take that into consideration and move at insect speed if anyone considers this approach for the first time. The best reference I can spot is at http://www.youtube.com/watch?v=I3dAOv2Oke0&t=6m11s where the power button is on the right hand side of his right hand. I'll try taking photos or video if it happens again.
I'll try this

P20 Pro Power Button Stuck = Constant Reboots

Hi All,
A few days ago the power button on my P20 Pro started to become faulty (running android 9.1.0.372). The button itself still clicks and does not appear to be stuck. However when it is pressed it does not lock the phone, instead after a few seconds it brings up the restart / power off option and then automatically resets (I assume due to the phone thinking that the power button has been held down for 10 seconds). When the phone then restarts, it is 50/50 whether it automatically starts the 10 second reset timer again, or if it will let me into the phone for a few seconds before triggering the restart again.
In attempts to troubleshoot, I downloaded a button teester app, but it did not register the power button when I pressed it in. I have since managed to factory reset the phone, booted in safe mode etc betwee the random restarts but none of these have solved the problem. I've looked on the forum / Google and can't find any mention of this issue for any other user. It looks like a hardware issue to me and to get the button replaced is £200...
Any Ideas? Thanks

I feared as much, I have ordered some replacement parts to see if it is fixable
For anyone picking up this thread with a similar issue...
I fixed this a few days ago, ordered a new power flex cable (£2) and battery (£20). Heating the phone to soften the adhesive was a nervous moment, and the inside of my P20 pro was different to the instructions I followed online... After removing the motherboard and through a bit of guesswork, I managed to unstick the old power cable and the metal casing that sits between it and the physical buttons. When reinstalling the new cable, I popped the power and volume buttons out to ensure the correct alignment of the casing and the cable.
The old battery was really stuck to the phone and took a lot of pressure to lever out. Overall, managed to install the two new parts and for good measure, android 10 got pushed to the phone the day after! So it feels like a brand new phone now
