Hello all,
usually i deal with my problems by searching the forum, though this time i am really worried as i cant find anything to my help.
You see something went bad with the screen and because the phone is rooted, i cant get it fixed (it is still in warranty), nor can i use it (the touch sucks).
So i am trying to get it unrooted.
So i have downloaded LG mobile support tool and the drivers, i enter the phone to download mode and nothing happens. i get all the time errors. Also, in the lg mobile support tool, i see a software update. Should i do it? I cant though because the start upgrade button is greyed out, and the "LGD802" sign on the left pane is flushing like its trying to verify my g2. Also, should i wait for like 10 minutes or so when i enter download mode for the bar seen at the phone to be completed before the whole process? Lastly, the most of times the lg mobile support tool crashes on the pc.
Please help me folks... :/
the problem is when i hook my phone up the pc and it recognizes it, it starts the download drivers part but it freezes and force closes...
Hello. I am using a D802. I tried the rooting solution with the DP Tools this morning. Since I got past the first step where it needed access to the phone the USB drivers must Work, and they still do. I am in Dev mode.
When I get to the second step, I need to enter download mode, but if I hold the volume up button and then put in the USB after, it will just start to charge. I am not completely sure, but I don' think recovery mode is working either, since the "up + turn on" combination just turns my phone on and off, repeatedly.
However, my phone is working fine otherwise. Re/Boots up fine, internet is working, calls/SMS Works, and when plugged in to the computer, the name of the phone is LGE_Mobile (As in, it is not 'qhsusb_bulk').
Is the phone bricked, or does it need some other fix?
I just wanna ask before I start go through the different fixes, especially since my only computer with a Linux OS, that seems required for one of the fixes, is broken until monday.
Thank you.
Fixed
Posting reply just in case others were having same issue. I fixed this by simply updating my phone through the LGMobile Support Tool. I am not sure what Android version I had before, but I suspect quite old. Now I can easily access download mode, haven't tried recovery mode, and except for hiccups the LG G2 works fine now.
Today I got my new Xiaomi 3S (4G, 3GB RAM, 32GB ROM) played around with it a little bit and disabled all Google Apps to be found on the phone Except Google Services that couldn't be disabled.
Connected it via WLAN and got promptly OTA offered. I didn't wrote down the MIUI and Android builds but remember manufacturing date August 2016, MIUI was version 7 something.
After the updates where downloaded I was asked to reboot the device what I confirmed and the updates where installed. Now the phone is stuck with a black screen and white "MI Powered By Android" on it.
Nothing changed since 3 hours now. Any idea what to do?
Phone can't even be turned off/does not recognize hardware button presses.
This is a known issue, disabling google apps causes issues . You should now try following this guide http://en.miui.com/thread-327861-1-1.html

Thanks a lot for your reply, tried it already yesterday while the Phone was in endless boot queue without luck, hence the non working buttons update.
But today after the battery was emptied over night I got into the recovery mode menu!
Just a question before I go ahead to follow the step by step guide:
Though I read this thread/vote I'm non the smarter. If I want to go google free, Xiaomi Global or Xiaomi EU ROM?
I'd also use XPosed framework with XPrivacy again. IMUI seems nice, is CM 13 the only alternative for non google/XPosed/Xprivacy then?
I currently have a 3s prime but it's a present for my son so haven't flashed anything, just take ota's. I have read quite a bit though and you should maybe just check the rom threads for roms with separate gapps packages, that way you could remove what you want prior to flashing. Don't know about xposed but again, ask in the rom threads. [emoji106]
Update: No success, when going into recovery mode (pushing volume up and power button) and choose download mode the phone will just reboot into endless boot-loop.
For people with the same problem (after disabling google apps) maybe they can get their device back to work with this http://en.miui.com/thread-378963-1-1.html
The only Way to get you phone back is to use a Deep Flash Cable i think
I was able to solve the problem by installing a fastboot-rom. Pressing power button and volume + for around 20 seconds got me into recovery menu.
Than I was just following a guide to install an original MIUI rom on devices with locked bootloader.
well to get to download mode you can enter "fastboot oem edl" without the "" and you will go to edl from fastboot mode. HOPE THIS HELPS

Now I know why my phone went into a bootloop. Won't disable any Google apps anymore.
Disabling any apps in MIUI8 will cause the phone cannot reboot... you can format everything through a recovery (have to flash manually because it doesn't come with recovery), or flash a new ROM through fastboot mode (if you have unlocked your bootloader), or send back to service center to claim warranty (if there is any service center in your area), or throw it and buy a new one

I have same problem but in my case developer option is locked so oem is off and thus port COM10 is not being shown in Miflash, also fastboot oem edl says device is locked, oem edl is not allowed. In my case 3s prime went into bootloop while Iwas using youtube. Please help!!
Hi All,
I'm new to this as I'm not an Android developer but a good Android user. Requesting moderator to update anything required.
I've Xiaomi mi A1 and it was working for the last 3 years. Last Sunday, it just got hanged while kids were playing with it(maybe multiple apps/videos/some ad clicked) and it got hanged.
I restarted and it stuck on "Android One" screen till now even after multiple attempts.
What I tried:
1. I tried to wipe/factory reset from the Android recovery option(power off + volume up) then it stuck there saying "Formatting data" and I've restarted it to come back to Android One screen after hours.
2. I tried using MiFlash tool and it continues throwing the error "remote device is locked. cannot erase".
Then I got to know bootloader must be unlocked. and for that:
1. I tried fast boot oem unlock but it just says OK and device reboots. When I check status back, it's again locked .
2.I tried to unlock it using MiFlashUnlock tool but it says not able to find account details as I may have logged in once but probably I may not have used Xiaomi as cloud instead I prefer Google cloud.
You can assume I'v already searched possibly all threads on the internet and added here all possible information.
Attached getvar-all.txt output
Is there anyone on the platform who knows on this issue?
Or it's just a platform of Ads?
oooooof, sounds like a harsh brick from some sort of malware downloaded into the device or your kids diddled with some kernel settings somehow
is your device running on qualcomm snapdragon? i have the fix for it in this site
but first try the update option on the recovery, might fix something

found some fix on a russian website, gonna translate it:
im gonna make a warning there off-script of the russian website, this is NOT guaranteed to work. if it doesnt, send it off for repairs.
what do you need to do this:
1 - fully charge the phone
2 - a working usb cable
3 - a computer with wifi on it (i can tell you have it since you likely posted it on the computer)
4 -you should have Mi flash pro
5 - a recovery image on chinese (WARNING: 1.9 GB, BE PATIENT)
6 - actually working braincells and hands ( you guaranteedly have em)
THE STEPS:
1 - Load in mi flash pro and register in it under your name (not always under your name)
2 - press recovery
3 - you should see a lightning bolt icon along with the IMEI of your device
4 - type in the path of the firmware
even if your device shows your system has been destroyed you can still boot into recovery.
5 - in your device boot into recovery
6 - you see connect with mi assistant? choose that option and confirm it
your device should direct you to connect the usb from your computer to your device
7 - After you setup everything you should see your device, if not, press refresh device, then you should see the flash button, press it
8 - and there begins the magic - wait 5-10 mins for the firmware to initialise, DO NOT DISCONNECT THE USB FROM YOUR DEVICE AT THIS POINT, IF YOU DO, YOU WILL SCREW IT UP AND HAVE TO DO IT ALL OVER AGAIN!
if you dont screw up and your device actually boots congratualtions! the power of xi jing ping has restored your phone to normal with a small drawback - its all in chinese
worry not, it doesnt end here:
9 - Unlock the bootloader AKA Unlock OEM (This is important, because otherwise you will brick yourself again and will have to do it all over again)
10 - boot your device into fast boot and flash the global firmware onto your device (the global firmware can be found on the same xiaomiui website you got the chinese firmware from)
i hope this lengthy guide helps

crud, i forgot the critical part:
it doesnt boot you to the average xiaomi screen, its the A1 model
at this point you need to use the ADB to flash the chinese firmware and unlock the bootloader on the chinese firmware, then flash the global one
though you can still use the same method i typed above
How's the progress so far?

Hi i dont have that kind of a problem!
my problem is when i try to do oem unlock it says error 0x1002 and idk what to do (i have same phone btw) i tried anything but nothing works!
Hello...
I am looking for a working way to root my SM-T555
The device is running android 7.1.1;
base ver. "T555XXU1CQHA";
build ver. "NMF26X.T555XXU1CRG1";
Samsung experience 8.5;
Android security patch August 2017.
So far, the several attempts I made using every T55X related software I found in this website have been unsuccessful.
It would seem that the rooting software available is for "Marshmallow only", thus not Nougat specific,
though I read some comments stating that the TWRP made for MM worked on Nougat too and, after that, Magisk would/could do the job...
So I gave it a try but, after installing the recovery, my tablet got stuck every time: refused to boot normally
and if I turned it off, long pressing the power key, I couldn't turn it on again as if it was bricked.
Every time I had to re-start it in download mode and re-flash the original stock rom with Odin in order to have it working again.
On top of that, the "OEM unlock" key is not present in the developer mode list: none of the "date changing tricks" I found around the web seems to fit this model.
I am inclined to believe this "might" be the mother of my problems in rooting the device though, supposedly, the patches were not for Nougat, anyway...
The developer options page, once activated, can only be "turned off" ("greyed out") but cannot be deactivated;
while, on other devices, if you turn it off the page usually disappears after rebooting then you have to tap 7 times the build version, again, in order to make it appear.
I never had problems in rooting any of the phones and tablets I have /had, including an SM-T819 running Nougat 7.1.1,
thanks to the great job done by the coders in this community to whom I would like to express my appreciation for what they do for the benefit of us all.
But this thing seems to reject everything I throw at it and it's been the most stubborn "phone like object" I ever fought with.
So far I am the one loosing the fight... I wish some of you guys could give me the means to defeat it.
Thanks in advance to whoever may be available to help me out.

thanks for your reply.
maybe my post was too long and boring so you didn't read it all
Of course I already tried the solutions posted in the page you suggested but they did not work.
not the autoroot files, not the recovery, etc...
I quote: "after installing the recovery, my tablet got stuck every time: refused to boot normally

If there is a TWRP file specific for my Nougat version available I'd be happy to give it a shot

Did you follow a guide when flashing TWRP? Did you unlock your bootloader?
You need to be clear and concise in your posts as yo what you did and how.

of course I did follow the guide by the book. also, the recovery appears to be installed properly, Odin showing a nice green PASS sign, but it doesn't work anyway
now about unlocking the bootloader, as I mentioned in my first post:
"the "OEM unlock" key is not present in the developer mode list: none of the "date changing tricks" I found around the web seems to fit this model.
I am inclined to believe this "might" be the mother of my problems in rooting the device"
every time I had to re install the system, so there clock want back to zero. Maybe I should be waiting for the allotted number of days to pass on order for the OEM unlock key to appear...
but before my first attempt to root the device, almost one month was past and the OEM unlock key wasn't there, notwithstanding...
I hope there was a chance that the bootloader was already unlocked...
to be concise (schematic):
tablet in download mode
untick auto reboot in Odin
AP loaded with "smt550_cf-autoroot.tar"
flash with Odin, OK, green sign PASS
reboot manually home+volume down+power,
then switch to volume up when screen becomes black
the Samsung logo appears and stays there indefinitely
So I turn the device off, long pressing the power key
then I try and turn on the tablet but does not turn on anymore,
not even pressing the power button for 30 second
then I press home+volume down+power again
to enter download mode and reinstall stock rom
(the same happens with
sm-t550_p550_p555_cf-autoroot.tar
or twrp_3.0.2-1_sm-t550_mm_7816.tar,
I also tried
twrp_3.1.1-1_sm-t355_251117
remark: none of them mentions T555 nougat)

What process did you follow to unlock your bootloader?
Stop trying to use Autoroot. Let's figure out what we need to do to get TWRP on your device. Once we do that, you can flash Magisk in TWRP for root.
Please read this guide, sections 1 through 4 (don't worry about the GSI stuff) and tell me what you have or have not done.
ok, I wasn't able to do this:
Unlock Bootloader
Enable Developer Options and turn on OEM Unlocking
OEM Unlocking is missing in the list, as I mentioned in my previous posts
I tried the date change trick but it didn't work

This is the first step. You cannot flash custom or modified images if the bootloader is locked.
Connect to the Internet and check for updates in system options, then check Developer Options again.
I did that step too, several times:
the system found an update available
the first times I cancelled the download
then I downloaded the update without installing it
then I tried and installed it
no result at all the attempts: the OEM Unlock key does not appear in developer options

it is the first time I work on this specific device, so I couldn't tell: so far I couldn't find the OEM unlock option in the list
it never happened before on any of the several devices I have rooted in my life,
included another Samsung tablet SM-T819 running Nougat 7.1.1: the option was right there and all I had to do is tick it.
I used fastboot for other brands
I wish there was a way to use fastboot to unlock the bootloader on Samsung
if there is any I don't know it
adb is working, but when I give the "adb reboot fastboot" command, the tablet enters the download mode and fastboot does not see the tablet anymore from the computer

Samsung devices do not have a fastboot mode.
Since this is a Snapdragon device, it probably cannot be unlocked, especially if it was marketed in the US.
Only Exynos and international Snapdragon devices can be unlocked, unfortunately.

actually I am in Rome, Italy so I am quite positive it was marketed here...
is there a way to know for sure whether or not it is international?
the Samsung SM-T819 I am writing from has a snapdragon chip
but I had no problem unlocking/rooting it,
I bought both the devices here in Rome
now that's a mystery...

Usually the model number is a good indication with phones - the G908U vs G908N for example, but I don't see that being the case here
Have you tried signing into a Samsung or Google account on the device before checking for updates and looking for OEM Unlocking?

on a freshly installed rom:
I connected the internet thru wireless
signed into my Google account
completed the tablet configuration, etc
then I went and enable the developer options
no OEM Unlocking yet again...

You manually checked for an update too?
Did you try disconnecting from the Internet, disabling network time, and manually setting the time ahead 1 week?
