Hi guys, first of all this is my first post here and won't be my last.
I am an Apple/iPhone long time user and want to tryout Android, just because I think it's time for a change , without knowing if I could get used to the new OS and wanting to spend as less as possible on this "endeavor" I bought a second hand Galaxy Note 2 GT-N7100 from a friend, the phone worked perfectly when I bought it, it had Android 4.1.2 on it and I wanted to update it to 4.4.2, did some research on the net about this (learned about the locked bootloader - this wasn't an issue for me coming from the iPhone) and updated the phone using Kies - and this is were the fun begins.
The update failed, and the phone was softbricked but could still go into download and recovery mode, after reading a few hours on the internet, I used Odin to flash a 4.3 stock rom for the n7100 which I downloaded from samsung-updates, the software got installed on the phone but it was very laggy (with the phone opened but locked, when I pressed the power button it took about 7-8 seconds for the display to light-up, the animations were very sluggish and phone was unusable).
I installed another ROM, using Odin, this time a 4.4.2, with the same results (every time I reset to factory setting and wipe cache from recovery - this didn't help).
I then installed clockwork recovery and rooted the phone then installed cyanogenmod 10.1 which worked almost ok but if i locked the phone after a few seconds the phone would restart, wipe cache/restore factory settings didn't help, i installed it again hoping it would be just an issue with the installation but had the same result, phone would restart.
I've followed all tutorials I could find related to this phone and this issue, installed several patches, reinstalled several stock roms, installed Criskelo rom, all with the same result, the phone is very very very slow and freezez after a while or it restarts after i lock the phone.
So, let me just give u some history on the phone, enumerate the symptoms and where I am right now:
History:
The phone was bought from Vodafone Romania, was never rooted and was never updated (before me ) and still has 3 months warranty.
Symptoms:
- Phone is very slow, unusable
- Freezes after the display is locked
- it is not recognized in windows, when I connect it i can hear the windows connect chime but the phone storage is not mounted, in device manager the phone is recognised as "cdc communication interface" which is not installed - i have the samsung drivers installed, and i have tried on other PC's with the same result, I also tried with several data cables - same thing - the phone works ok when in recovery/download mode
- sometimes when the phone is connected to the PC and the screen goes dark a gray battery appears with a "wait circle" and the phone freezes
- in recovery the phone displays 14 bynaries downloaded and also knox warranty void 1
- most of the roms freez in the language selection screen - i boot-up the phone (after i do a restore factory settings) the installing application dialog appears and then the language selection screen appears, then after 5-6 seconds the phone freezes - the freeze is not triggered by something I do it's triggered by time, after 5-6 seconds no matter what I do with the phone the phone freezes, if it makes any difference, exactly before the phone freezes the display brightness goes to the maximum setting.
Where I am right now
- I installed another stock rom, 4.4.2, it worked acceptable for a few minutes (it got passed the initial setup with no issues) then i left it on the desk, the display went dark and the battery thing happened again and the phone froze, i restarted the phone in recovery, did a factory reset, when the phone started it froze on the language selection screen.
I am at this for about a week now and I have no more ideas and no more patience, and run out of threads and tutorials to read, I am 1 step away of using the phone as a paperweight so please help, any idea would be appreciated, even if it's to enlighten me about what happened and telling me that the phone is bricked.
I am willing to try anything even if it is risky and can totally brick the phone, this is not my main phone and it's purpose is to help me understand android, and help me not make the same mistakes next time.
But, if it's possible I would like to fix the phone because even though it's pretty old it's still an ok phone.
Sorry wrong forum. You need N7100, not the n7000. Good luck.
Hello everyone,
first of all thanks for your amazing work and all the stuff you provide. I was a silent reader for a long time, but now my phone is trolling that much, I cannot fix it on my own/with the guides I found here.
I do have an HTC One M7, rooted (superuser) and S-OFF (revone) with Androidd Revolution HD 71.1. I used to update my ROM every month, but I got stuck after the last update. My recovery was TWRP as CWM did not work properly when I rooted my phone.
My issues as a list:
- cannot enter recovery anymore
- cannot connect via USB (tried every port)
- screen turning randomly black on homescreen and sometimes in apps (but they usually work), screen does work, but i cannot see a thing
- since today graphical issues after a reboot (flickering screen, parts of the screen get duplicated)
Since the last update I cannot enter recovery anymore. Getting in bootloader is no problem but i get stuck in the "entering recovery...." screen. It does not move, tested it for some hours. I tried updating the recovery (-), trying to flash stock recovery and reflashing custom (-), trying cwm (-).
After I tried cwm i noticed that it didnt overwrite the recovery but i got both. cwm and twrp, but i cannot delete one of them (didn' work before either). I can start TWRP oder CWM on a booted phone, but updating both bugs and I can't enter recovery with these tools too.
Today I wanted to try again on my own, but my phone won't connect on USB. Tried every port on my computer with and without USB-Debugging. I will try on a other computer, but I could not do this until now. Additionaly I want to wait for some ideas of fixing, as I think "my" trys are not going to work suddenly .
Screen started to turn black a few days ago. Dont know why but I think it could be a software issue. but i cannot update (see above ). When i try to turn my screen on it often just turns instantly black. soft keys are enlightend and it does work (more or less). if i success in sliding down the service bar on the top, i can start my alarm clock app and from there use the soft keys to get in other started apps. From there it works most of the time. Sometimes i need a couple of trys, sometimes it just works as its intended without turning black and sometimes i need several minutes to succeed.
Cannot say more as I did to the graphical issues. Just had them once until I started an app (screen worked). could not reproduce this error.
I would prefer a solution without wiping, but if necessary i will ofc.
Thanks in advance for your help, as I am rather helpless right now.
I attached a photo of the bootloader.
Yours Laexxi
Hello everyone,
I have-or had- MI5 with latest cm14.1 on it, today I downloaded the latest rom from xiaomi.eu -Nougat-. I rebooted into recovery, wiped partitions, flashed the new rom, flashed successfully, and then flashed a font zip, the installer hanged at unmounting system for a long time, I forced rebooting it through holding power button the phone turned off and then never worked. nothing happens, no led when connecting to charger, pc does not recognize the phone at all, no sounds when connecting it. recovery and bootloader does not open. it is completely DEAD. Any help?
same h ere except i didn't get any errors while flashing except the normal command[log] error for all nougat roms. phone is just dead with no signs of life.

I got this error as well,
After some search it seems using a deep flash cable could, I cannot make one currently so maybe you could take a look and try it
http://forum.xda-developers.com/showpost.php?p=69727277&postcount=2
I just checked the second post in the xiaomi eu thread
"- NEVER wipe /system partition manually in your life!"
hmm, I have always done this
Edit:
Many people reporting the same issue their.
There's another way to go to EDL mode which is this

I haven't tried it yet as I don't have copper tweezers.

People reported it worked in xiaomi eu thread, gonna try once I have the tools, I wonder why the * dev didn't write "- NEVER wipe /system partition manually in your life!" before the download links

Do follow the videos, i was hard brick 2 times but now it's working
The issue is, you flashed the CM14.1 on low battery, this then messed up the battery reading, while your device showed somewhere like 50% infact it was around 10%, what need to be done is, do a hard reset with power button a few times while connected to a charger, use a new charger/cable and let it charge for a long time, itll then switch on and charge, leave it to charge till 100% then do a full wipe including internal storage and install a new OS

I don't really think that this is the problem because the "rom" flash completely successfully. I don't think that the font flash would cause all this mess. Anyway, I left it charging overnight and I keep pressing power button with vol +/- but nothing happens. Thanks anyway. it seems I have to either use test points or deep flash cable.
Hard bricked the phone with the same ROM here, tried to solve it with the video's testpoints (making contact between the two dots and plugging the USB).
Fortunately, MiFlash with adb and qualcomm drivers recognized the device. So I flashed many fastboot ROMs (miui 7/8 dev&stable) via MiFlash, but none of them made the device wake up. The only signal of life is the led blinking red when connected to a usb.
Still trying...
EDIT: ok, got it booting now. The red blinking led is actually a good sign, it means low battery. I just let it charge for about 20 min and the led changed to yellow, and then I could boot it up.
It seems like in all that time the phone was plugged into my PC usb port for flashing, it didn't charge the battery. So I think we should take into account what Shaky156 said, just in case.

I just revived my mi5 using the test point method, it is rather simple actually.
Make sure you are using miflashtool beta,
I downloaded this rom china developer
I noticed that even though I chose save user data, I still lost my data.

Good to know it also worked for you, I just didn't believe that my battery was depleted from 70% just by hardbriking it...
After installing TWRP it asks to decrypt data even though I did not encrypt, hmmm what now
Edit:
I just did factory reset in TWRP and now I can see sdcard.

I also had my Mi5 die earlier today. Here's what I did to get it back:
1. Popped-open the back cover, removed the screws from the top panel
2. Disconnected battery (left side)
3. Connected battery back
4. Shorted the two contacts at the right side of the board
5. Plugged original USB in
Note that using a deep flash cable is a less intrusive way of doing steps 1-5, but that's what worked for me.
At this point, the PC detected the phone in EDL mode. I then attempted to flash the fastboot ROM for Mi 5, however, I kept getting errors about Missed Hello / Issue with COM port.
6. Downloaded an up-to-date version of Mi Flash (beta didn't work for me), disable Signature Enforcement (Windows 10) and install Qualcomm drivers
7. Downloaded a MIUI 7.5 fastboot rom
8. Flashed, got an error, about storage being not enough... But the screen turned on with the Mi logo. I was finally able to get the phone into Fastboot.
9. Successfully flashed MIUI 7.5 ROM using Mi Flash.
If you are still getting the COM port issue or Hello, try disconnecting the battery again and repeating steps 3-5.
Good luck.

Thanks for the reply, but I already fixed it this way. I used miflashtool beta since the final release did not work.
The problem is did you lose your data after the flash? because I lost mine even though I checked save data in miflashtool

At that point, I didn't really care if I lost data since I didn't have much on it anyway. Nice to hear that you got yours back. Those were dark hours, yes?
Thanks for giving a hope (checking way to recover from video). I'll get proper screwdrivers soon and try do the same.
I have narrowed down the issue, its the nougat firmware thats caused these recent issues. Xiaomi has distributed an unstable bootloader. I highly recommend reverting back to marshmallow firmware and OS

I can confirm that this 100% works for me. You need to be a bit patient with the tweezers and getting the contact points right. It didn't immediately work for me, and I think I had to try a dozen times at least. But eventually it did recognize it. Once MiFlash can see it, you need to use the latest China stable rom. I tried the latest china dev, but it kept on giving errors of missing hello packets.
Hello,
my Redmi 4x won't boot. I tried to find some solution for this issue, but I can't find it anywhere, so I created this new thread to ask you for your help.
Last night I was out in the city and my phone died because of low battery, so after I came home I just wanted to charge it as usual. Battery logo showed up and it was behaving as always, but when I tried to turn it on it couldn't boot again.
After pressing the power button the splash screen flashes for a brief moment and then it just turn off again. This happens all the time from the moment my phone died. I'm not sure what went wrong here. I can't get it to recovery mode either. So I wanted to do a fresh start and flash it again with new ROM here (Ressurection Remix 6 is what I have now)
I'm able to get it on fastboot mode, but once I try to flash it with MiFlash I get error message like "error:FAILED (remote: Critical partition flashing is not allowed)"
So I looked up for a solution and I found that I need to get it in EDL mode with adb.exe
I tried this solution but with no luck. Phone is restarting but it won't turn on again and the fastboot mode is lost.
I'm not really sure if I have right drivers for it. Qualcomm HS-USB Diagnostics 900E is what I have now. I can't also change the usb debugging mode obviously, so I'm also trying to find some solution for this issue either (is there any chance how to turn it on with adb.exe?)
I think it's softbricked but i'm not really sure.
Thank you for your help

Hi, most likely your battery is faulty. Current draw during Android kernel boot up phase is above 1A whereas only around 0.2A for a working OS, that's why neither OS nor recovery can start when the battery develops high ESR (internal resistance). Do the following test:
fully recharge the battery
do not disconnect the charger
turn it on
Your Android may now actually work again but you must use a short quality cable connected to a 2A+ charger, which will support the battery at boot time - and you can disconnect it later.

Thank you, but the battery wasn't the main issue, because once I was able to flash it through EDL mode to the latest stable official ROM, the battery was on 93% already.
Now I'm stuck with MI logo and powered by android with 3 blinking dots above. I watched somewhere, that it could last for 7 minutes, but for me even the 15 minutes is not enough, so I guess i'm in bootloop.
For some reason my bootloader is locked again, even though I already made the unlocking process earlier before I flashed to Resurection remix 6. My phone doesn't even appear in device manager. I can't even use it as a storage, so I could try to flash it to custom ROM.
I'm not really sure wat happened and how is it possible to brick your phone by just draining your battery to 0%
Ok, phone is alive again. It booted up right after I inersted microSD card in slot. I didn't know this was necessary...
