hmm that sounds bad dude, first don't try stuff you aren't sure of !
Second, you are lucky that you can access boot loader; most nexus become paper weight
here are steps to get it back to life.
1 ) download nexus root toolkit 1.80
2 ) select your device and ROM what was running on.
3 ) there are icon buttons first install drivers using first button.(Full driver installation guide etc)
4 ) then go to the button that is flash stock+unroot {make sure to check current status(soft bricked) }
5 ) then if you have a stock room saved, select that or choose auto( it will do all the steps it self )
6 ) it will download and install through boot loader mode
have fun
I had that similar problem, like mentioned before me.. Download thenexus toolkit aand either try to flash stock firmware or you might have to download the original firmware (which is easy to which) and then side load or manually push the image to your tablet

Hey people, can anyone get me a MTK droid backup of UMI ZERO? I need it to see if i can recover my bricked UMI

Hello, you can get the rom including scatter file from Needrom! Just flash trough sp tool and you will be fine.
Sent from my UMI ZERO using XDA Free mobile app

Hi there raducux,
Well, this was about another situation, but mixing with ROM's cooking I was able to brick it again it was mrsim who help me (mod at china-devices.com, credit where is due). But I will tell you how I did it.
You need to have the adb android drivers installed and flashtool v5.1 or up (the one I used, but some people use the 3.1 version).
Download this ROM from needrom (scatter file compatible with FT).
Link: http://www.needrom.com/wp-content/uploads/2014/11/Y800_UMI_20141104_1907xx-s7yler.zip or
http://www.needrom.com/download/umi-zero/
Extract, and in flashtools select the scatter file inside the directory you extracted. Press flash, and (after pressing flash) connect the phone to the USB port holding the volume down key (so the phone connects in META mode), and the process should begin.
If all works well after flashing the phone should boot the new ROM, its version 3.01 so you have to upgrade it.
If that does not work, tell me a few things... I suppose the phone does not start or appear the 'Zero' logo, but tell me if when you connect it to the computer you ear the normal plugin USB sound?
FlashTools (all versions)
http://helpadude.com/sp-flash-tools/
Universal ADB Driver
http://www.needrom.com/download/universal-adb-driver/
Tell me if it worked, or if you need more help tell me what happened and how the phone responds. lot of people here also that can help. My 1st thing I check when buying a new phone (for many years now), is if it's 'XDA' Supported...
cheers

i am running antarct s emui . with twrp recovery... i need dto know the sp flash tools steps correctly to flash back to stock
preloader doesnt install correctly in pc because volume down...takes me to twrp...and volume up...to the chinesse recovery of huawei,
so preloader starts installing, but when in recovery..it gets dissconected
Could you tell how did you put it in meta mode? I have a Zero with no preloader and in windows it shows up as unknown device. No matter how I try to boot it up (vol- vol+). Other than showing in windows, it's dead. Is there a way to revive ti?
Today I wanted to switch to CM13 which I found on this forum. I messed up, phone got stuck in a reboot loop, got it into download mode and put it back to a stock version. Now however, I am not able to root my phone using ioroot. This is all I get when I try to root my phone, then it just stops.
Code:
Enable ADB connection..
Developer Options unlocked and ON.
USB debugging ON.
Accept RSA key fingerprint.
Press any key to continue . . .
Waiting for ADB detection...
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
When trying to change to a different stock ROM with LG FLASH TOOL 2014 I get the following error when my phone is connected to my PC with MTP.
Code:
The phone is disconnected from PC.
Connect the USB cable and wait a moment. Press the Retry button to resume the setting analysis process.
My phone is still connected, pressing the retry button brings up the same message.
When I select LG Software instead of MTP I get the following error.
Code:
To try upgrade again, follow the steps below.
1. Disconnect the phone from PC and remove hte battery from the phone.
2. Insert the battery back and reconnect the phone to PC.
3. Turn on the phone.
4. Press the Retry button below to start the upgrade.
I can't remove the battery, pressing retry after a reboot brings up the same message.
Software information:
Code:
Android version: 4.4.2
Baseband version: M8974A-AAAANAZM-1.0.190084
Kernel version: 3.4.0
Build number: KOT491.D80220h
Software version: D80220h-EUR-XX
Hardware information:
Code:
Model number: LG-D802
Memory: 32GB
So what do I want to do? Switch from the current ROM to a different one, as that is currently not possible for me. After this I wil retry to put CM13 on my phone. I am out of ideas (not that much experience) so hopefully someone on this forum can help me out!

Hi,
You don't need to install any further firmware. Go to this thread: http://forum.xda-developers.com/lg-g3/general/guide-root-lg-firmwares-kitkat-lollipop-t3056951
And root your device using the tool. It should root just fine.

Sounds great, so I went to check the root with Root Checker which says the following when I validate my root: "Sorry! Root acces is not properly installed on this device".
Would you have any other suggestions?

Awesome worked, in hindsight I should've probably done some more reading up. Because I honestly have no idea what to do next. Should I install AutoRec,find a lollipop ROM install. Then root again, install AutoRec again, download CM13 together with GApps and flash these onto my device? I do realise that im starting to go off-topic, so if this is not allowed I'll post it in the official CM13 forum. Thanks for your help anyway!

You don't need to go through all of that.
First, make sure you have the latest TWRP downloaded to your phone along with the hybrid LP bootloader for your phone.
Then, download the CM13 Rom and GApps you want to use to your phone.
Install KK AutoRec and reboot into recovery.
Flash updated TWRP and reboot back into recovery, then hybrid bootstack and reboot back into recovery (not sure entirely necessary to reboot, but it always works for me). Then you can flash most Stock-based LP or most CM13 or AOSP MM roms.
---------- Post added at 07:30 PM ---------- Previous post was at 07:26 PM ----------
One more thing - important! - take time to read through the thread of any roms you are interested in before flashing them. This will give you an idea of what, if any, issues you can expect and if any tricks are needed to get things working.

I have TWRP 2.7.0.0, downloaded the latest image from their websirte but for some reason im not able to install the image. I can't select the image within TWRP. The button that you would usually use to select images isn't there.
I've got a LG D802, so do I download the LP bootloader from here: http://forum.xda-developers.com/lg-g2/development/lg-g2-bootstacks-t3173715 ?

You can use Flashify from the Play Store to install the TWRP for your device. Make sure you look at blastgator 's TWRP in the G2 Android Development section as it has special thermal control for our devices that will help keep you from damaging your screen. It is also flashable.

Thanks for the heads up about the thermal problems, now on the thermal TWRP by blastgator. Downloaded the bootloader that I linked in my last post, flashed it and got stuck into a bootloop again. So now out of that bootloop, rooted again, and on TWRP 3.2.1-1 with thermal control. Should I try a different bootloader? Sorry for pretty much having to guide me through it with baby steps.

Problem is that I used a KDZ file to get the KK ROM on my G2 so I don't have any img. files.
You can kdz back or try getting back into recovery. If you get back to recovery, you might want to consider trying twrp 2.8.7.3.

KDZ'ing back means using the LG Flash Tool 2014? Because this doesn't seem to work as it says I haven't connected my phone to my PC, even tough it is connected. I cannot get back into recovery or download mode.
EDIT:
I just noted that the screen goes to black, so it's still on. No idead if this is important.

So you rooted and installed twrp. Then go ahead, make a full nandroid backup on an external usb via OTG and then try installing cm13 , follow steps provided by cm13 thread here.

I suggest go back to stock, upgrade till 5.0.2 lollipop and then root, install twrp via autorec and flash cm13. I did the same and it works. Lmk if you need further assistance.

Hi,
If you are having issue shutting down your phone because it keeps booting back, then hold the power button ( keep holding it) until it goes black, reboot itself and goes black again. Then press volume up and insert usb into your pc to access download mode. It should fix.
If you simply cannot get into download mode, follow this guide : http://forum.xda-developers.com/showthread.php?t=2582142
LMK if it helped

Revive Dead/Hard Bricked/Dead after Flash/LED doesn't light up the phone - K8 Note (XT1902-3)
If you tried to downgrade from Oreo to Nougat and your device is hard-bricked. Don't worry, follow the procedure below...
1. If your device is fully hard bricked and doesn't boot up by pressing the power button, and also the white LED light doesn't light up while u connect the charger/power on the USB to the PC. Try pressing all the 3 buttons, Volume Up+Volume Down+Power Button for about 25-30 seconds and connect your phone through USB to SP Flash Tool (install all drivers before as said in step 3) and see whether it detects your phone (If it detects, go to step 3). If this also didn't work, don't get panic - follow step 2 (Dismantling your device - the only way to recover. But be cautious while doing it, use proper tools).
2. Remove your phone back cover carefully and disconnect the battery connector as shown in the video
. Use proper tools and a screwdriver. Connect the charger and see now, the LED light will blink surely (If it doesn't blink now also, then it's a hardware problem, you should go to the service centre only).
3. If the LED light blinks properly, then go to SP Flash Tool (download the latest version here - https://androidmtk.com/smart-phone-flash-tool), and in Options->Option go to Download and check USB Checksum and Storage Checksum. Then choose the option Download Only in the drop-down list. (Dont Forget to install all Drivers before - MTK Drivers and Lenovo USB Driver, links below)
MTK (USB DA COM,Preloader USB VCOM,USB Port,USB VCOM) Drivers : https://spflashtool.com/download/Driver_Auto_Installer_v1.1236.00.zip
Lenovo USB Driver : https://lenovousbdriver.com/download/lenovo-driver-v1-1-33
(CAUTION : Don't select Format all+Download because if you mistakenly chose Format All+Download option it will delete all your IMEI no, Device Serial no, WIFI MAC address, and Bluetooth Address. But don't worry you can retrieve it through this method : https://forum.hovatek.com/thread-12328.html or
. Make sure you know all your IMEI no, and device serial no {You can get that from your device box, there will be a label in it}.
4. In the Scatter-Loading file click Choose and load MT6797_Android_scatter.txt under the extracted Oreo Rom (whichever version you prefer)
COUNTRY: GLOBAL
Oreo Stock Rom OMB 27.43-20 -> https://drive.google.com/file/d/18iZb3sumLUEBNNAYDfRVa3t8fJZVCXgg/view (MANNING OMB 27.43-20.7z ~ 1.40 GB)

Wait for some time until it loads........
5. Now click on Download Button. Then switch off your phone and keep pressing the Volume UP button while connecting your phone to the PC through USB.
6. Now your phone will be flashed successfully and you will get a message Download OK. Close that and remove your USB and Power On your phone. Your phone will boot in Oreo, and you have unbricked your phone!!! Enjoy!!!
Downgrade to Nougat from Oreo - K8 Note
1. First Unlock your bootloader through the following steps:
(Before this take a backup of all your files, apps, and data because it will factory reset your mobile)
{Unroot your phone if you're rooted, also Uninstall any modules or Xposed or rooted apps if installed}
i) Go to Settings->About Phone and Tap on Build number for about 7 times, this will enable the Developer Options. Now go to Settings->Developer Options, switch ON it, and enable OEM unlocking & USB debugging.

3. Extract the downloaded zip file and Go to Fastboot mode manually as mentioned before. (Switch off, Press Volume UP+Power button at same time. Release Power button while phone vibrates. Then Choose Fastboot option using Volume Up Key and select it using Volume Down Key)
4. Connect the USB Cable from phone to PC and Double click the flashall.bat file inside the downloaded zip. {Rename flashall.txt in the attachment to flashall.bat, if you didn't find it from the downloaded zip}. This will flash the Nougat Rom fully on your device. Sit Back for some time, and relax.

See this video if you have doubts how to factory reset using recovery mode :
7. Then select Restart System now in Recovery Mode (Volume Up and Volume Down to Select between options and Power Button to OK). Viola...!!! Your system will reboot and your'e on Nougat Rom...!!!
{Note : After downgraded to Nougat, you won't get OTA update to Oreo. But you can get all the OTA updates of Nougat. Main thing: Don't use "fastboot oem lock" in downgraded Nougat Rom it may brick your device. Because while you lock the oem in downgraded version, the system updates will look for Oreo Rom so it wont boot as you already downgraded. If it's bricked try flashing Oreo Stock Rom using spflash tool. So try keep the "device unlocked. Orange Status......" text that comes while you boot up, always in downgraded Nougat Rom}
Follow the procedure correctly so you can retrieve your K8 Note, don't blame me if you totally damaged/bricked your device.
Hit Like and Press Thanks...!!!!
If you have any doubts you can mail me at [email protected]

If u have installed twrp in oreo get rid of that and go for stock oreo recovery, if u have rooted already on oreo means unroot your mob, uninstall xposed/magisk manager if it's there. Then start the process with unlocked bootloader, go to fastboot mode and run flashall.bat inside the Stock Nougat Rom zip. After the process finished successfully the device will boot automatically. You may get some errors or not, no probs about it, go to recovery mode manually and factory reset your mobile. Restart the mob. This will surely work. Go for it...
Anyways, I feel good that you retrieved your phone back through Oreo Rom. :good:

Try factory resetting using Recovery mode, if u can go through it. Else flash Oreo Rom through latest version of spflash tool. Only Downgrade using fastboot mode....
Given Oreo Updated ROM for K8 Note links, check it...

Can Lenovo k8 note Android p unofficial ROM.
Hi, xda developers is there any way that Lenovo k8 note can get Android p ROM. If yes please reply?
Hi @xda Team,
couldn't find any threads releted to Sharp Z2, which would match to my issue, so that's why I'm trying it in this forum.
I have Sharp Z2 phone (https://www.gsmarena.com/sharp_z2-8410.php).
I tried to root it and to install/flash TWRP recovery on it. Because of realy less information for this phone it was difficult to find proper files.
So I tried with an official version of TWRP.... didn't worked.... after long time, I found on an chineese forum some instructions for flashing the TWRP through ADB/Fastboot.
Bacause I have successfully used this technology already several times on other phones, I was happy to have finaly found something AND forgot to check the skripts
The result is, that after unsuccessfully flashing the bootloader got blocked trough this script (OEM blocked). Now my phone is not booting. I have no access to FASTBOOT and to RECOVERY mode.
I have found an unbrick instruction for LeEco s3 (based on x620) using the SP Flashtool (I have used it successfully for my other phone LeEco S3).
Following this intruction on my Sharp I'm getting following message:
"BROM ERROR: STATUS_SEC_PL_VFV_FAIL......."
It looks to my, that I have not all permissions to flash the phone.
SO still NOT BOOTING, NO ACCESS to FASTBOOT AND TO RECOVERY MODE.
Also on XDA Forum I found this guide for an ASUS Phone (https://forum.xda-developers.com/zenfone2/help/thead-bricked-phone-updating-to-mm-tips-t3452785)
UPDATE:
SP Flashtool is not able to load the preloader file. Always stops with the same error: BROM ERROR: STATUS_SEC_PL_VFV_FAIL......."
In some forums I've read that flashing with wrong preloader can cause my issue and that in this case there is nothing there to save / recover the phone.
I still hope, that because of the Android OS there is still a chae to unbrick it.
Please HELP!!!
Thanks in advance.
mine is in a similar state but i still have access to the fastboot; i can reboot to bootloader or recovery but only to acccess fastboot. there is no recovery tool left on it and attempt to flash twrp - various versions of those have all been failed attempts. handset is still in the brick state with access to fastboot but no use.
please help to get this working again, given the fastboot is working, can i use any other recovery tool except for twrp to maybe get to having OS flashed?

I don't understand why to flashing preloader
TWRP --- Install ROM or SuperSu.zip
firmware under flashtool
Click on the SP Flash Tool "Download" and connect the switched off phone with the Vol "-" key pressed as on the screen, the tick on the Preloader is not worth it! Release the key a few seconds after filling the 100% red bar. Wait for the end of the firmware and the appearance of a green tick. Disconnect the phone from the PC and try to turn it on

So i did with a firmware i found on 4pda forum for sharp z2 using this guide http://4pda.ru/forum/index.php?showtopic=870393&st=100#entry76931735

Still dont understand what i am doing wrong..
