Please help! I am new to this and am worried I bricked my phone.
I successfully rooted my Verizon Samsung Galaxy Nexus using a toolkit. It was then working fine with 4.2.2. I wanted to install Shiny Rom 4.4.2. I thought I successfully backed up apps and data using Titanium Backup.
I successfully moved the correct zip files to my phone, and realized I needed Clockworkmod recovery. I followed a procedure to get this on my phone by using my computer's command prompt. I successfully booted into Clockworkmod recovery and followed the process of wiping data/factory reset, successfully installed radio and bootloader recommended to install with ShinyROM but got stuck and could not install the ShinyROM itself. I think it is because it requires a later version of Clockworkmod. The one I downloaded using the procedure was 5.5.0.4, but I think I need a later version. I tried following the same procedure using my computer's command prompt and it got stuck at "waiting for device". I cannot get out of Clockworkmod recovery now (even battery pull, etc.). I then found some threads saying I need to restore my old ROM first. (I think) the only ROM on my phone is ShinyROM. I am stuck and stressed out because I do not know of a way of "pushing" the new version of Clockworkmod to my phone.
Can I fix this, or do I need to start shopping?

i think u already wiped data partition at first, that why your Rom installation aborted bcoz recovery cant mount any partition.
still got your old system partition here.
from recovery ~ try adb sideload your shinyRom. can your pc detected bootloader (fastboot)/recovery?

Regarding partition, I have an option to wipe cache partition. Should I do this?
Update
Well, I went ahead and tried this, and still could not install ShinyROM.
I tried to follow a procedure in the link to use ADB sideload.
I downloaded (full) SDK and updates and updated the drivers. When I get to the following steps from the procedure...
-Boot your device in recovery mode (Android logo with a exclamation mark) and connect your device to PC
-Hold down "power" button first, followed quickly by "volume up" button. You should now see the recovery menu
I only boot to CWM and there is no Android with Exclamation mark. Holding down power button only selects whichever option is highlighted within CWM.
Also, it seems within CWM, there is supposed to be an option to sideload a zip file. This option does not exist in my version of CWM.

Thanks. I found another thread that led me to the same conclusion, except I was able to do it with CWM and fastboot the latest version using ADB sideload. I still haven't posted enough to link, but here were the details from user camblue.
"
If you know how to use ADB you can always fastboot a recovery.img,,,,this thing is almost impossible to truly brick. IN order to get into fastboot just connect to your computer and run adb with these commands
adb reboot bootloader
once in fastboot mode write this
fastboot devices
that will tell you if your device is connected and reading in fastboot mode if it is you will see something like fastboot and some numbers next to it. If nothing you do not" have the fastboot drivers installed.
then to fastboot flash a recovery.img write this
fastboot flash recovery r3-recovery-clockwork-touch-6.0.0.4-nexus7-modaco.img (or whatever recovery.img you are using or have in your tools folder of you SDK location).
and in order to get right into CWM if you cant boot write this
fastboot boot r3-recovery-clockwork-touch-6.0.0.4-nexus7-modaco.img
hope that helps

Hi guys,
I would really appreciate any help getting out of this pickle (my first time trying to install a ROM).
Here's the situation:
- Running a Huawei P6-C00 Chinese phone
- Was interested in trying a custom ROM (e.g. CleanRom by @surdu_petru) in order to enable Google Apps
- Updated normally to B120 CN as instructed
- Rooted (using Root Wizard)
- Installed customer recovery (TWRP 2.6.3.3)
- Started flash process including advanced wipe in TWRP... wiped system, cache, davlik, etc... :crying:
- Realized that I didn't have the ROM .zip copied to the phone yet
Currently, I'm able to boot into TWRP but cannot connect using adb for sideload (TWRP just says starting sideload but never connects). What do you guys recommend? I don't have a backup of any working ROM or the stock image.
Is there a way to initiate a "standard" restore since I wiped all the caches? ...
Are there some tricks to getting ADB running so I can try to sideload the ROM again? ...
P6-C00 does not have an SD card, but is it possible to load the ROM onto a USB and read it from TWRP?
Thanks for any help!
Did u try connecting to adb?

Hi Taaeem,
Thanks for the hint. I read some posts on fastboot and tried the following, but could not get into fastboot mode.
Methods I tried
- Power off phone and then power on while holding vol-down button
- Select Reboot -> System option from TWRP, while holding volume down
- Select Reboot -> Bootloader option from TWRP
From what I understand, fastboot mode should be run from the /boot partition, which I didn't wipe. So any ideas how I can get into fastboot mode?
Thanks again!
Okay, I confirmed that I have at least some kind of fastboot access because I tried "fastboot reboot-bootloader" from command prompt on my PC, and it rebooted the phone (but the phone stayed on boot logo).
- Next time I get fastboot, should I run "fastboot flash [partition] [ROM-file.zip]"?
- If so, what partition should I specify? I'm confused about where this command will send the ROM file, and if so how do I find it from TWRP later on in order to install it?
Thank you!
One more update:
- Even though I'm stuck at boot logo when I try to enter fastboot mode, it looks like there is a somewhat working fastboot connection. I tried running "fastboot flash [partition] ROM.zip" but it fails after 16s ("remote: flash write failure" or "remote: partition does not exist"). I tried flashing to cache / data / system
Should I try @N!ELS huawei p6 suggestion of accessing by Linux? (I don't have one nearby) or am I using fastboot wrong?
Thanks!!
Also:
- I noticed that when I boot into TWRP the device shows as "..." in my system tray USB devices list.
- When I try to boot into fastboot mode, the device shows as "Android Sooner Single ADB Interface" (but phone is still stuck on boot logo)
- However I'm still not able to connect using ADB .. shows "error: device not found" in all cases)
- Finally, after powering off the phone does show the stock charging animation, which gives me hope that this can still be saved :crying:

fastboot mode on the P6 doesn't have any kind of ui for fastboot, so it stays on the boot logo, fastboot should work fine.
You could always find an USB OTG cable and connect a FAT32 partitioned mem stick with the .zip on it, TWRP allows flashing from USB memory as far as I know
You are definetely not out of hope, but im not sure about the compability of P6-U06 roms with the C00 variant.

Obviously you can't flash the whole zip file to every partition, infact you can't flash a .zip at all, atleast not in fastboot mode, .img extension is used. So don't try flashing the rom manually via fastboot, since you have a high risk of actually bricking the device, if not in the right hands.
Also when booted into TWRP, try "adb devices" in the cmd see if anything shows up.

Okay that's good when you are stuck at the logo and you can see your device at your PC you are in fastboot mode, from here you can work with fastboot commands NOT with ADB that will not work. Anyway isn't there a option in TWRP where you can mount your device to USB when that work you can just copy the files on your phone without to go with fastboot. When that don't work you must try to extract the .zip from the ROM you want to install and flash every image with fastboot I think that should work.

Okay so now I'm a bit paranoid about hard-bricking the device, and would rather not try my luck on a ROM that isn't approved for the P6-C00, haha...
At this point I just want to get a working OS installed (restore to the default for P6-C00 phone, even), and then maybe try to safely enable Google Apps. Any suggestions on how I can get this restored?
- I think the device came with a USB cable that is OTG.
- Seems like fastboot is also working, even though "fastboot getvar xxx" returns nothing useful
- ADB does not work while booted into TWRP (can't run shell, sideload, or list devices)

Download this rom for example https://disk.yandex.com/public/?hash=bhDlIAc5AqKh4RAB2IdatPdEfYVI9FH/Zky/UTGcH3M=
Extract the .z7 and run the flash_all.bat, this scripts flashes the rom via fastboot and you should get your device back up and running again. And from there you can update to a newer firmware version without problems.
If the bat doesn't work try this:
boot to fastboot
fastboot flash system system.img
fastboot flash cust cust.img
fastboot reboot recovery
Wipe cache and dalvik cache in twrp

Thanks, tauio111! That worked and I now have a working phone again :victory:
I'm going to be a bit more careful about how to enable Google Apps... this is too much stress during the workweek haha.
Later on what do you think my best option would be?
- Wait for a confirmed easy to install ROM for P6-C00 that supports Google Apps
- Some other way to enable Google Apps with the standard firmware, since I am rooted?
Thanks :laugh:

Heya Tauio111, I'm having the same problem as onetree and I've been frying my mind over this for the past 4 days before I came across your solution. I found that your link is no longer working, may I ask what that ROM is and where else I may find it? Thanks!

A way that may help (i've done it with boot&recovery images). Using this tool http://forum.xda-developers.com/showthread.php?t=2433454 , might give you the *.img files necesary for flashing the stock rom through fast boot. All you need is to follow the instructions on the tool and have a stock rom (update.app file type), and some knowledge on how to use the fastboot.
Hi Guys,
I kinda did the same thing here.
I accidently wiped my system with TWRP v2.6.3.7
I also have a huawei ascend p6 u06
I didn't realize i never copied a rom to my device so i don't know how to install.
I can't seem to be able to use adb or fastboot and my device is not picked up by windows (8.1), it just says removable disk in my computer.
and under device manager it says P6-U06 under unknown devices.
I have tried to install a bunch of different drivers to attempt something but no luck.
Please help me.
Hi I tried to OTA on my D802. It downloaded the latest update file, rebooted to TWRP, then I had to manually instlal the update and since I did it it bootloops to TWRP.
So I wiped all data, system .. everything and via USB-OTG flashed clean OS and gapps. Anyway Im not able to boot to OS even I press BOOT TO SYSTEM in TWRP.
I updated TWRP to the latest 3.0.3-a (originally I had 3.0.2-1.
I cant boot to OS and my D802 is useless. anay help ???
thank you
Petr
Manually like fastboot? Are you sure you did not flash TWRP to boot instead of recovery?
Sent from my Nexus 6 using Tapatalk
My D802 downloaded new nightly build and rebooted to TWRP and nothing happened. So I install the new nightly manually in TWRP.
Since I did it it reboots only to TWRP.
Tried to wipe all in my phone including internal storage etc. and installed new fresh Lienage (tried more nightly)
I even tried to install it from fastboot and it boots only to TWRP itself even I use BOOT TO SYSTEM in TWRP.
i had no chance to flash TWRP instead of updated OS since there is only lineage-14.1-20170306-nightly-d802-signed.zip and open_gapps-arm-7.1-stock-20170308.zip on my flash (OTG)
update: It does not matter what ROM do I install to my D802, I get TWRP bootloop only ..
Solution
I know the solution of this problem just read carefully
You have to do it from the fastboot.
Google your device and learn how to enter into fastboot mode after switching off the phone via pressing combination of hardware keys.
Then Google and download the exact same following files for your phone model not others (wrong files will brick your phone). Following are the files :-
1 boot.img
2 droidboot.img
3 recovery.img
4 rom.zip
(All the above mentioned files should be the official files provided by the manufacturer company of the phone)
Now download the basic Windows or mac or Linux driver of your phone for the computer you have and install it in your computer, then restart your computer and also install the "minimal fastboot" in your computer and then connect your phone while phone is in fastboot mode, then copy all the above mentioned files in the folder where the minimal fastboot driver is installed.
Now go to that folder where minimal fastboot is installed in your computer and press shift key and while keep pressing the shift key right click the mouse and select "open command" here.
Note Google and learn the command how to check whether your device is connected to your computer via fastboot.
Then install all the mentioned files using fastboot commands.
Hurry you have your phone with official ROM and then if you want use the same technique you may have used earlier to unlock bootloader and root your device and installing the latest twrp.recovery and then lineageos.
Now your phone is unbricked and you have latest lineageos.
Also remember the ota update of lineageos is broken so don't install updates via updater app.
The safest method is to download the whole update package and put it into your phones internal/external/usb otg drive and install via custom recovery.
Be happy
जय श्रीराम ?????
SOLVED, the solution is simple, i just quickly installed the adb drivers during the TWRP screen showed up... have to attempt a few times but finally get it to works, then i flashed the rom using fastboot mode
Hey, i was in twrp and i wiped data and system, and it suddenly reboots...
after booting it shows some error messages then it reboots again in loop... i have no OS installed currently
i tried go to fastboot mode, installed adb drivers on 3 different computers each running windows 7, 8, and 10 but still cannot detect the device in fastboot mode...
anyone knows the solution ?? Thanks Before...
If video not show up, heres the link https://www.youtube.com/watch?v=FDQqBLMvD0E
See the attachment to see the error message
- download "P2a42_S048_161111_ROW_fastboot"
- Download this file" flashall.rar"
- Go to the file "P2a42_S048_161111_ROW_fastboot" and unzip it .. !!
- Unzip the file "flashall.rar" and move the file to the folder (P2a42_S048_161111_ROW_fastboot / sw )
Then Install ROM ... by fastboot mode ... and clicking on the flashall file

Don't do this if you don't want to have your phone baseband completely removed meaning no sim card function at all. I did exactly this when trying to install stock room and it deleted my baseband. Luckily I had made a backup a month before that. I restored it from the backup and the phone (sim card) started working again.
Anyways, back to the original issue. So you're saying your phone isn't recognized in fastboot? When I wipe system and data and then go into fastboot and enter "fastboot devices" it shows nothing but I can still flash files into the phone. I'm guessing this is because the phone has no 'name' due to the system wiping. So try going into fastboot on your phone, connect it to PC and open adb, and then enter the command 'fastboot flash recovery twrp.img' (download the latest version of TWRP for Lenovo P2 and rename it to twrp).
If then you are able to enter TWRP after rebooting, download stock Lenovo P2 ROM and flash it.

Hello, I have a huuuuge problem.
Every time I try to flash TWRP through cmd, nothing happenes. I have all needed files, my phone is being recognized in adb devices, reboots on command, is on fastboot devices list, reboots on fastboot reboot command, but it totally do nothing when I use fastboot flash recovery twrp.img command. Maybe it's my drivers fault, because last time i uninstalled my device through Device Manager, somehow it worked and I flashed TWRP. But then I switched to MIUI and as expected TWRP was removed. And I cannot flash it, please help
Did you update to latest MIUI?
Yes, right now I'm on Global Stable.
Turn your pc into a new one then you will.
Why turn your PC into a new one? resetting?
Isn´t there another solution?
Removes old data such as adb,platformtool, twrp.then can do it.I've come across and solved this way Do not know why

Posted another tread:
I struggled a lot installing TWRP. I did not succeed flashing TWRP from my PC. My solution was:
Starting up TWRP: fastboot boot twrp.img / boot command only boot and does not flash.
Thereafter installed Magisk 17.1 from TWRP for rooting
Thereafter flashed TWRP / I tested flashing both by using Flashify and TWTP Manager and both worked.
Maybe by using Flashify I had to use an older version of TWRP. Think TWRP Manager let me install 3.2.3-0 direct without problems.
