Phone occasionally enters fastboot - Xiaomi Mi 5 Questions & Answers

Hi,
I've noticed that, when I take my phone out of its (magnetic) car holder, I often find it in fastboot mode. I'm don't know why, but I suspect one of the following:
- I mistakenly press the power button as I take the phone out of its holder, without noticing, and it's probably too sensitive, and somehow I touch the fastboot mode (if there is such) in the power menu.
- My car holder is a magnet, and it may affect the phone. I've already noticed that if I use the magnet in a specific place on the back of the phone, the touch functionality is lost. If I move the phone just a bit, the touch is restored. Maybe releasing my phone from the magnet can cause the phone to enter fastboot?
Does anyone else experience this?
Thanks,
Shlomy

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

G1 with no screen image, keys not lighting up. Help?

Hi everyone ...
I recently disassembled my G1 to fix the touch screen. I acknowledge that I took the phone's fate into my hands when I decided to open it up, but I had done this twice before with no problems whatsoever. If these symptoms sound familiar to you, please let me know if you were able to fix your phone.
I put it back together, and now when I power it on, I get the short vibration that confirms the power-on ... but I get no screen image, no keyboard lights. So when this first happened I pulled the whole thing apart again to be absolutely sure I hooked up all the flex cables and ribbon cables. Yes, everything is connected. Everything. I've triple-checked it now.
What I did next was a couple of tests to see how "awake" or functional the phone actually is behind that blank screen. When I power it on and let it sit a couple minutes, so that I know it has finished booting ....
I CAN:
- boot the phone in normal or recovery mode. both modes produce the blank screen and no key lights.
- view the phone in ADB. (ADB tells me "device" or "recovery" mode)
- execute commands and view files on the phone with ADB shell.
- pull files off the phone with ADB.
- make the LED light up by plugging in the wall charger or USB cable when the phone is off.
I CANNOT:
- make any of the backlit keys turn on by pressing them.
- make the phone receive a call or a text.
- make the LED light up by a missed call, text, or plugging in the charger/USB when the phone is on.
My first impression is that I've done something terrible to the mainboard so the phone is somehow in this "semi-booted" state, where it won't run the screen. Is it possible that a bad cable to the screen could cause this? Thanks so much for your help.
Come on, no one can help me with this? I know I'm not the only one who has taken a G1 apart and met with disappointment.

Eventually it will stop working all together like mine has.
If you're not bootloader unlocked, then just call htc.
If you are, go ahead and either download an app of the market that will let you skip/disable the lockscreen or use a ROM with trackball wake/unlock built into it.
Also, if you power button stops working altogether, you will probably want to set your screen time out really low.
Finally, if your phone cuts off, the only way I have found to cut it back on is to plug the phone up to a USB cable and let the charging light come on, then remove the battery and as soon as the light cuts off put the battery back in and the phone will cut on.
I can't remember which on it is, either holding the volume down key or the trackball but one holding of those two will allow you boot straight into fastboot instead of hboot, because if you boot into hboot you have no way of accessing any of the other options since your power button is broke, but when you boot straight into fastboot you can at least apply a nandroid. Once I had a rom that broke adb usage and got stuck on the flash screen and I thought I was screwed until I happened to boot into fastboot, so these are just a few tips for you if it quits working altogether on you.

[Q] Way to reset with fastboot? Button issue...

This is a somewhat strange problem that I have, I've got a G1 which has none of the front keys working, other than the trackball. No talk, home, back, or end keys. The only way I've gotten it to boot is to plug it in and insert the battery, which causes it to power on. I got it from a friend who replaced it with a MyTouch3G.
I've been using this phone for the last few days, it is my backup (other than a RAZR...). It was still on 1.6, with a build of DRC83. It was kind of difficult to use without those buttons, but I could use the keyboard search button to just search for whatever app I wanted to run and switch apps that way. I previously had a B&N Nook, and I remembered that SoftKeys worked on it since it had a lack of hardware buttons, so I started using it, although only the home button worked without root. All of the tutorials I could find stated that I needed RC29 or lower to root (I assume they're all old) but I finally figured out that UniversalAndroot would do the trick.
I should have just been happy with that, but the phone had no more room for apps, and I was hoping to use Apps2SD, so I flashed ClockworkRecovery, downloaded CM6.1, and attempted to flash it, which now has me stuck in a boot loop at the 'ANDROID' text logo. I can get into fastboot (the camera button works). But since the home button is inop, that's my only option. Is there anyway to reset or restore the phone via fastboot? I've read that I can restore a nandroid backup that way, but for some reason the nandroid backup I made didn't save on my SD card (it must've crashed or failed to write or something). Is there any way to get another image to flash via fastboot? I couldn't find a stock image or anything. Am I just stuck? I thought about getting a broken phone off of eBay and replacing the buttons, is that my only option?
Thanks for everything you guys do on here, you all are the best!
is the button completely inop? what is your phone stats? radio, hboot etc...? i have a un-root method but you need recovery so i guess you cant do that... im not to sure about fastboot i will check for you though...

Yes, all the buttons are completely inop. I disassembled the phone earlier and found the culprit.... the connection port on the daughter board which the input module plugs into has been sheared off of the daughter board (the board which houses the micro sd card port, the USB port, and connects to the input module, and which sits underneath the button assembly). Before disassembling it, I ordered a new input module membrane off of eBay, but it now seems likely that I won't need it. I'm not sure if there is a way to re-solder the port back onto the board, but I doubt it would work and my soldering skills aren't exactly the greatest. This of course makes perfect sense, since the trackball was the only part working; it connects directly to the daughter board, bypassing that broken port. So, in the meantime, I'll work on getting a broken G1 off of eBay and hope that it doesn't have a messed up daughter board.
Basically, if there was a way that I could get into recovery, I'd be good to go, but I can't. A few other things I've found by searching: apparently fastboot is accessed by holding the back key while booting? I was booting while holding the camera button, I had just tried it and assumed that it was the same thing. I noticed that it didn't seem to actually be in fastboot when I connected it to my computer (fastboot devices didn't show anything). So I might just be 100% stuck until I get the buttons fixed. I did see a version of Amon_Ra recovery that used the Menu button as an alternative to the Home button for confirmation, which was made for somebody with a broken Home button, however, even if I could manage to flash that recovery, I don't think it's possible to boot into the recovery with the keyboard Menu button.
I'll post the phone stats I get on Camera+Power On once I put the phone back together tomorrow. Thanks for the help!

[Solved] Hardware issue with power button

Build date 1007 - in service August 2010.
I've been running Pinnacle 1.2 (been on it since v1.0).
Just moments ago I've found the power button to be unresponsive. This happened after I rebooted into recovery, sticking me there for a while.
I was stuck in a recovery loop- pull batt, reinstall batt, automatic boot back into recovery.
Somewhere in the process of trying different combinations of battery pulls with cable installs and volume up/down holds (trying for download mode) I ended up finally launching the ROM, but w/o a power button all I can do is pull the battery, and the moment I do, the phone automatically wakes w/o even touching the power button (which is totally new to me).
Any input would certainly be appreciated.
My first order of business is to flash to stock (JF6, bootloaders and all if all else failed) but being that it automatically boots when the battery is installed I don't think even a jig would help...or is the beer steering me wrong?
I am confused. You can go back to stock or no?
I cannot get into download mode. The only way to power the phone off is via battery pull.
I cant flash anything from recovery because it says the power button is disabled (it is).
As I put the battery back in the phone boots immediately...I mean the at&t screen lights up my palm before I put the cover on or even flip the phone over.
Use an app from market to enter download mode? system toolbox free is one
Used Odin to go back to stock KF1 and still no power button. Now System Toolbox won't work w/o root/busybox. lol
Once my phone falls asleep I can't wake it back up.
It may seem obvious that the power button is physically broken but I don't know why the phone boots up as soon as the battery is installed...that was never the case before this issue came up.
watsa? Anyone?
Can anyone else shed some light on what would make the phone boot when the battery is inserted (happened at the same time the power button became unresponsive), essentially denying me the opportunity to get to download mode.
beyond this point I am consfused myself. I initially blamed Pinnacle and thought going back to stock might fix it which obviosly didn't happen.. It seems like your power button is always "pushed" so as soon as you pop your battery in phone reboots..

On a second thought if it was the case then power button should have messed up functioning of your phone even after powering on. So I am consfused more. Need a hardware expert here
I'm preparing myself to deal with my beloved phone finally letting me down after all the success we've had...it's just really bad timing as I'm currently unemployed, broke and only 13ish months into a 48 month contract.
Ok, so after a physical tear down it seems to be in the external plastic of the button itself?
After removing the outer case and reinserting the battery I noticed it did not automatically boot up. I pressed the actual power switch/button that is connected to the board and the phone then powered up. I let it finish booting and held the power button down and the power options menu popped up. I clicked Power Off and it shut down fine.
This means it certainly isn't Pinnacle ROM (never thought it was, personally), or software related at all. Now to figure out what is going on between the plastic external power button and the power switch on the board.
Edit: Nothing was there? I blew out the dust reassembled the phone and now it works fine. Weird.
