Bricked Your Phone? Try This.

Well, long story short my friend royally screwed up his phone.
He screwed up the kernel and even the Recovery. Don't ask how.
We even connected the phone and ADB didn't work on bootloader. But after we went into fastboot and tried a restart it worked. So.. we used fastboot to restore the phone.
Notes before you start: Use command prompt and cd to the directory for your sdk tools. In my case, I simply used the 'data' folder for the Toolkit that was released here that had the sdk tools like adb.exe and fastboot.exe . MAKE SURE you copy the associated recovery zips and ROM zips to the very same folder to prevent complications and for the commands to work like a charm. Finally, uninstall the drivers for your phone and reinstall them (if you need to only, as we had connection issues.. yep he royally screwed up).
Boot into bootloader then select fastboot and hit the power button. Keep it on the fastboot screen. Now you can proceed.
Here is what I did:
fastboot erase cache
fastboot flash recovery recovery.zip *rename your recovery zip to 'recovery.zip' and make sure it's in the same folder as the sdk tools*
You can now then boot into recovery and write the ROM or even use fastboot to write it with the following:
fastboot flash zip rom.zip *once again, rename your ROM zip to rom.zip*
I only put this out there to help those who screwed up their recovery and can't even get the Toolkit to execute commands using ADB.
Good luck!

Yeah, fastboot on pc then in command you clear cache and install recovery. I got into a boot cycle and this fixed it.

Glad it worked. Yeah, for some reason my friend's computer was being really fussy. It wouldn't detect the phone or anything, and ADB was rendered useless. We reinstalled the drivers so many times.. And used 2 different laptops.. Thank God fastboot worked. Hopefully this helps anyone else in the same **** zone. I know the heart sinking feel when your Recovery won't work and you only get the bootloader to work..

[Q] Help: Bootloop after installing CWM (video) (tried google)

So I brought myself in a bad situation.
Here's a video showing what the phone does and me trying to get into CWM:
http ://www .youtube. com/watch?v=5F2Gg_eU7Yw
I was trying to root my sony xperia z1 compact using this guide: http ://techglen. com/2014/02/05/root-xperia-z1-compact-d5503-4-3-14-2-a-1-114-official-firmware/
Following the steps it asked me to CWM 6 using this guide: http ://techglen. com/2014/02/05/install-cwm-6-on-xperia-z1-compact-d5503-4-3-14-2-a-1-114-official-firmware/2
I checked firmware and version of my phone and everything was correct.
I must admit I have no clue as to what I'm doing but I'm normally ok with tech stuff and the guide seemed detailed and trust worthy so I thought I could do it following the guide.
I got the bootloading unlocked just fine and started to install CWM. I made it this far:
- After downloading CWM kernel zip (Its not the actual name of file, just a reference name), place it in internal or external SD Card of your smartphone
- Now extract CWM kernel zip on your PC’s desktop and copy boot.img
- Paste this file inside the folder where you have installed Minimal ADB and Fastboot
- Now turn off your smartphones completely
- Plug in mobile’s USB in cable in PC port only
- Hold Volume up button and plug in USB cable in mobile’s port
- LED will turn blue (If it does not remain blue for long, then read Optional part in bootloader unlocking method explained above
- Once you are successfully in fastboot mode, then you can continue
- Now type Fastboot flash boot boot.img and press Enter
- It will flash boot.img file on your device
- Now unplug the device and boot it up
- As soon as you see purple colored LED, start pressing volume up and down buttons repeatedly, until you are in CWM mode
- In CWM Mode, select “Install Zip”

I downloaded CWM .img file, placed it in my ADB folder and placed a copy on my phone. Using ADB I flashed the CWM .img (bolded step), unplugged the phone and the CWM screen came up and I was able to navigate using the volume buttons. So far so good.
At this point I realized that the CWM .img file I had downloaded and placed on my phone was not a zip file and I couldn't find it. So I hit reboot to boot up my phone normally so I could place the .img packed as a .zip file on the phone. Some error message came up, but I didn't manage to read it but caught something saying root I think.
As it rebooted the sony logo came up but then the purple led turned on and it seemed to boot into CWM again. A brief screen explaining how to navigate came up as you see in the video below (but with no menu options to actually navigate) before it rebooted and repeated.
I can still use ADB and fastboot, but I can't get into CWM and I can't boot normally.
Edit: Just tried "adb devices" and it says "list of devices attached" and then it's just blank. I can't push files onto the phone (error: device not found) but I can still reboot the device fusing fastboot and there's no error when I try and reflash cwm. Reading up on this it would seem that usb debugging has somehow been turned back on so adb can't acces the phone but fastboot can. Any way to turn on usb debugging through fastboot?
I tried a forced shutdown using the off button next to the sim card but it didn't help.
The phone is not recognized by my computer so I can't place or delete files from it.
Here's a video showing what the phone does and me trying to get into CWM:
http ://www .youtube. com/watch?v=5F2Gg_eU7Yw
If I don't press the volume button it will just keep looping in the sony logo and purple led light.
What I want to do is get back to a normal boot, remove the CWM .img file and put the .img file packed as .zip file onto the phone and retry the process.
I have googled a lot of options, but most results are a year old and I hardly understand half of what is being suggested. If anyone could please walk me through the process in a language that a total idiot can understand I would be so grateful and hopefully get my sleep back.

I hope you made a backup of your phone.
It may be worth wiping everything and flashing the Z1 stock firmware on to your phone. Stock firmwares can be found relatively easily by using Google. There are also lots of different video tutorials on YouTube on how to how to revert back to stock firmware and on how you can escape bootloops. Try this: www. youtube. com/watch?v=j4gm9VeQCHA

[HELP] Android not booting [URGENT]

It's a bit urgent to get solved, I'm at college, and that's the only way to talk with my parents, being 1 or 2 days without answering them would be a problem, since they will start to get worried.
Phone: Motorola Moto G 2014, XT1063
Using Team Win Recovery Project v2.8.0.1
Basically I was trying to update to the Android 5.0, since I had my phone rooted, I decided to go with an customized ROM.
DIdn't understand why, but it f**ed up.
Basically I cleaned everything, and in an act of desperation I also lost my sdcard, I've been trying to install the ROM through sideload, but it's not working, I get the error *failed to write data protocol fault no status*, and the phone keeps rebooting, and stuck in the "WARNING BOOTLOADER UNLOCKED"
I appreciate any kind of help, as I said, it's really important to solve this ASAP.
Thanks in advance!

Sir,
Please wait until mods will move this thread to the device specific forum for more relevant answers.
Stand by
Good luck

1) download TWRP 2.8.4.0 and install it through fastboot.
2) Since you have no sdcard we will use the mtp capability of twrp
-- Boot into your newly installed recovery. Check the version
-- Go to Mount and disable mtp and unmount everything. Now enable mtp. You should see that Data is mounting automatically and should appear on your Computer.
-- Transfer your ROM (I recommend The Titan Prime Rom for XT1063/64. It's based on stock and much more polished than CM12)
-- Download and transfer pa-gapps (MICRO MODULAR PACKAGE).
-- Download and transfer latest SuperSU (min version 2.45 is required by our device).
-- Wipe Dalvik, Cache, System and Data
-- Now Flash ROM, GApps and SuperSU. reboot and wait. it will take a couple of minutes.

Doppel u r right. follow doppel steps.

The device appear as offline in the fastboot, sometimes even doesn't appear, where can I get the drivers?
I searched for naked versions, and "universal" ones, but none seems to work.

You can get Motorola drivers here. You probably also need a recent version of adb and fastboot. You can ge it here Minimal ADB and Fastboot. Install it.
start "Minimal ADB and Fastboot" by navigating to the Start Menu Folder you choose to create during installation or the desktop shortcut you choose to create and select "Minimal ADB and Fastboot"
You should now see a command window open.
Put your device in fastboot mode and connect usb.
Now just do verify type this command
Code:
fastboot devices
the output should show something like this (your number is different)
Code:
fastboot devices
ZX1D225X69 fastboot
now put your recovery.img into the directory where your command window is open and start flashing
Code:
fastboot flash recovery NAME_OF_RECOVERY.img

You need a wall charger. USB from pc does not supply enough power. And you need at least 25% (ish) otherwise fastboot will refuse do do anything.

On the MOUNT and UNMOUNT processing I don't see anything on my PC, I don't even know how to unmount it. It only appears Enable MTP and disable.
How am I supposed to load the ROMS?
Tried with sideload but got an errror : "Error executing updater binary in zip .."
Seems like the drivers aren't working properly, I have Windows 8.1, on the site it doesn't talk about it, this might be the problem? Cause I instaled motorola device manager, I scan for drivers but it doens't find anything, and the phone apperas with the yellow triangle on the Device Manager.

Soft bricked phone? Can't install recovery and can't install a rom

Okay so I got my oneplus 3t today and I updated it to Nougat via the ota file all good so far. I then decided that I wanted to install a custom rom so I downloaded twrp supersu etc everything needed to root and install the rom. Here's where it went wrong in knowingly I downloaded the wrong twrp flashed it and it would just hang at the flash screen for twrp. Anyway after hours of trying to install a recovery I managed to get a stock one to semi work, now it turns out I don't know how I did it but my phone won't even boot it just turns on and goes straight to fastboot mode. I managed to get a stock recovery semi working but it won't let me install the stock rom from internal storage and I've tried updating through adb and it will hang at a random percentage for a good 20 mins and then just fail. Really need some help here it would be great, thanks

Hi,
If you can get into fastboot mode then the best recourse is through there. Hope you properly OEM unlocked your device.
First of all, you MUST have the latest adb/fastboot binaries and FOR SURE have the correct drivers.
Follow the links on this XDA article to download the latest adb and fastboot binaries: https://www.xda-developers.com/google-releases-separate-adb-and-fastboot-binary-downloads
This is the link for the Windows binary: https://dl.google.com/android/repository/platform-tools-latest-windows.zip
Extract all the contents of the zip file in a folder on your PC.
Then, also make sure to have THE CORRECT twrp, 3.0.2.0 or 3.0.3.0. This is the link but currently it is down: https://twrp.me/devices/oneplus3t.html
Download THE IMAGE, NOT FLASHABLE ZIP and put it in the same folder as the android platform tools above.
Finally, download the latest complete 3T firmware from OnePlus from this link: http://downloads.oneplus.net/devices/oneplus-3t/
I STRONGLY recommend not to use an update zip, even a full ROM update zip as that one might not include certain firmware images.
Put THE ZIP on the same folder as the others, DO NOT EXTRACT ANYTHING.
On your PC, open a command prompt in the folder where you extracted the android platform tools and run the following: fastboot boot twrp-3.0.3-0-oneplus3t.img (assuming you downloaded the 3.0.3 version of twrp).
Your phone will TEMPORARILY accept the twrp recovery as a boot image and boot from there. NOTHING IS BEING PERMANENTLY WRITTEN AT THIS TIME.
After that, enter TWRP's Wipe menu and wipe system, data and cache.
Finally, use TWRP's Advanced menu and enter adb sideload mode. Once there slide that slider to the right to enable adb mode and return to your PC and enter the following command in the command prompt:
adb sideload OnePlus3TOxygen_28_OTA_029_all_1612131737_17e7161d2b234949.zip (assuming you downloaded the 3.5.4 binary from OnePlus).
TWRP should properly flash the OnePlus ROM and hopefully, return you to proper function. You can then update back to Nougat.
Hope that helped!

Yeah that sorted it thanks a lot

Once I do "fastboot boot twrp" and get a success, then what?
Do I need to somehow reboot the phone into TWRP - because that didn't happen on its own.
If so, how do I do this?

My instructions while detailed are not step-by-step. I expect the person reading them to have their PC configured correctly and at least a vague idea of what they're doing.
So, assuming you put the correct TWRP image (my command uses the name of the image for TWRP 3.0.3.0, you MUST alter it to reflect the actual image's filename if it's not that) on the same folder as the fastboot binary then yeah, the command
fastboot boot twrp-3.0.3-0-oneplus3t.img
should have made your phone reboot and enter into the TWRP image that you had on your PC.
If it didn't then you did sth else wrong before that.
Either you didn't OEM unlock your phone when you still could or you didn't use the android platform tools that I linked or you don't have the correct ADB drivers installed on your PC.
Start from there.
Hope that helped!

Thanks for your help @KeyperOS - I know where I went wrong...
To save some time, when I tried to reboot into TWRP, I typed "fastboot boot " then I dragged and dropped the TWRP img file onto that line in the cmd window (rather than typing the filename manually) - when you do that, it appears to include the full path to the img - it was that that was causing the problem.
When I typed the TWRP filename manually, it worked.
The only thing that caught me out was after I'd installed the ROM (via adb sideload) I tried to reboot the device from TWRP recovery - this seemed to just hang. In the end I just powered off the phone using the power key, then powered it back up as per usual.
Checked that the phone booted to the first of the setup screens, then powered off/booted into fastboot mode, relocked the bootloader and it seems to be OK.
I'm now back on 3.5.4 again, which was what I was trying to do...
4.0.0/1 had felt a bit laggy, and I'd sensed some issues with wifi and BT, I can now run 3.5.4 and see how it compares - was I just imagining it?
Thanks again for the guide and your help - I really appreciated it

@PugRallye
Windows' command prompt has an autocomplete feature. If you want it to add the name of a file, type a couple letters and then present TAB, it's gonna complete the filename itself and if it's the wrong file you can keep tapping tab to cycle through all the options.
Really glad it worked out Btw [emoji4]
In my experience, 3.5.4 was great but 4.0 is a step up in both battery life, which IME is amazing and features, with it I almost didn't need root and certainly don't need xposed which was a first.

I have done all the steps but For some reason twrp is not installed and i still have the stock recovery. Please help

That's because the above only boots TWRP to root but does not install it. To install TWRP, when in booted with TWRP, you need to transfer the TWRP img to the tablet storage and then install it while in TWRP.

it is important to show the pathway to the file TWRP-3.0.2_TB-X103F-beta.img in the command line, like:
C:\Users\Public\Documents\My Videos\TWRP-3.0.2_TB-X103F-beta.img

Sorry for this newbie question.
Which part of the above rooting steps is rooting my tablet, what is TWRP doing and why do I need to install the SuperSU app?
During my first try I didn't boot the TWRP image rather I flashed it. But that didn't help at all.
After booting the TWRP image I was able to flash the SuperSU app.
The stock recovery is still in use.
Thanks in advance.

Read the steps carefully and follow the steps, it is a tested successfull strategy. To get deep knowlege about the background processes, please read the threads elsewhere in Web.

Hi everyone. I just want to clarify something about this procedure There's a lot of people being confused on how to get into FASTBOOT on some things, and that's stopping them getting anywhere from the beginning.
The Lenovo TB-X103F tablet doesn't have a way of booting directly into FASTBOOT. Turning the tablet On while holding either volume key and the On button doesn't do it directly. . . . . Firstly, there's 3 buttons on the tablet, I call them VOL- VOL+ PWR (again, that's just to clarify things 100%)
here's what must be done (well it's this way on the 3 I have on my desk, so I assume all TB-X103F tablets are the same) . . . . .
1) Turn the tablet off completely.
2) Press & hold the VOL+ button (the middle of the 3 buttons).
3) Press & hold the PWR button, release the PWR button as soon as anything appears on screen - Keep holding VOL+ button.
4) After about 8 seconds the familiar green android lay down will appear. Then, your recovery menu will appear.
5) Release the VOL+ button anytime now.
6) Press either VOL button to select BOOTLOADER on the menu (Bootloader is the same as FASTBOOT on this menu, that's where the confusion lies for many users).
7) Got Bootloader selected? now press PWR and let the tablet reboot itself.
8) it will show the LENOVO logo, and appear to be stuck - it isn't It's in Fastboot mode.
9) Plug in your USB to PC cable, and it'll install appropriate drivers on the PC (hopefully eh?).
10) Once the drivers are installed, test it by getting a Command Prompt in your ADB/FASTBOOT folder on your PC . . . .
11) type the command FASTBOOT DEVICES It should show you that your device is connected, if it shows no devices then either it didn't install the drivers, or something
else is wrong (there's about 30 things that can have gone wrong here, too many to go through in this quick guide).
12) The tablet will stay in FASTBOOT/BOOTLOADER mode until you turn it off (or the battery goes flat lol). So stay calm, there's no rush
I've mentioned about there being no rush, because if you choose ADB connecting from the recovery menu, it disconnects automatically after about 5 minutes -
This is Important to know because it can disconnect while you're pushing/pulling files from the tablet, and cause really nasty problems. Bad design eh?
But we're in Fastboot mode, so nothing to worry about like that

Successful root
It was hard, but I had finally had done it. I had figured it out it is easier just to go to the command prompt (I ran it under admin) and "cd C:/adb" (where you installed the adb fastboot software) while having the TWRP image file being placed there. I only wished that I had done it sooner. And for those who are new to the custom recovery it can be overwealming, but with patience and going through the files in the file explorer to find your main storage would lead you to the SuperSU file and successfully root your device.

I flashed TWRP...now what? I can't find any instructions on how to reboot into TWRP. I got into some sort of Chinese menu (PWR + VOL-) but I'm pretty sure this is the device test menu.

So I did the "fastboot oem unlock-go" command and adb said ok but my tablet just went to a black screen and won't turn on now and I'm not sure why. I also heard the Windows USB disconnect sound when i did it.

Would this work with the TB-X104F running 8.1?

Since a few months my tablet is stuck with the 'password changed, wait....' message. I had hoped that I could overcome this with the steps mentioned here. But unfortunately not
I can't start it anymore, so I'm not sure if it is in developers mode or not. Also, plugging the device in my mac didn't let it download the drivers.
Too bad, because when it was working it was a great tablet, now it's just a expensive drawer filler

I flashed TWRP...now what? I can't find any instructions on how to reboot into TWRP. I got into some sort of Chinese menu (PWR + VOL-) but I'm pretty sure this is the device test menu.

its the vol+ not - you need to press with the power button

so what exactly do i have to type at the command prompt to run twrp?,ive put the twrp img file in the same folder as the adb stuff.

3.) start command shell (cmd) in the fastboot instalation folder on your PC and check for the device connection with the command:
"fastboot devices"
fastboot shows notting

lenovo seems to have killed these tablets from the old lady next doors experience.. no wifi, no adb, no fastboot, no qualcomm, just unknown device, which loads NOTHING, no drivers work!!!
