HELP Please; soft brick

HELP Please; soft brick - Oppo R7 Plus

Hi everyone.
Ok back in August I purchased an Oppo r7plus "m" version not knowing the difference, from a 3rd party seller. I know I probably should've waited until the phone would go on sale in Canada but I wasn't sure if it ever would. So anyways the phone worked great for a while. I noticed that it came pre loaded with OPPO Tools and Super SU. I thought wow, this phone is rooted right of the box? Great! So I started uninstalling some native apps of which I thought were just "bloatware", everything went fine until I uninstalled the weather app.
When I turned the phone back on after restarting, it now goes into the OS but continuosly flashes on and off and you can only access the dropdown notification screen. Luckily from there I can still access the settings menu. I tried holding the power button and volume down button to go to the factory boot screen. That worked and in there its says the color os version, but in brackets says
(rooted).
I can only assume the phone is still rooted but is stuck in some sort of soft brick. I've been doing alot of reading into how I might be able to fix the phone but I'm having trouble figuring it out. I'm good with computers and all but not to this level and I never rooted an android phone before.
Please somebody HELP.

So I've downloaded the ROM for my phone model, r7 plus m, and I transfered the zip file over to the internal storage of the device. I then held down the volume down and power buttons to boot to color os recovery. Than I cleared cache and install from sd found the zip file and it started to run.
After about a minute or two into the installation it stops and reads "Installation Failed". I'm thinking I need a recovery.img file but I'm not sure. Even if I had that file I don't know what to do next.
Anyone have any ideas?

Hi, how did you sort it? Are you still in need of stock recovery? I have one for model F, dont know if it works with M model.

1. Download and extract my RAR files ---> HERE
2. Open your PC device manager
3. Connect an usb cable only to your pc then press and hold the phone volume + button and then connect the usb cable to the phone
3. In the device manager you will see Qhsub_bulk then release the volume+ button
4. Right click on Qhsub_bulk and choose update driver
5. Use one of the driver folders which you alredy extract to install the Qualcomm driver and you will see it like 9008
6. Your phone have to be charged very well for a few hours before you try to flash it.
7. Remove it from the charger then connect an usb cable only to your pc.
8. Try to press and hold the volume + and power buttons at the same time for a few seconds and connect the usb cable to the phone.
9. You have to see the driver in the device manager like 9006 (you can release the buttons) [it wasn't easy for me so keep trying]
10. Open the MSMDownloader and press start
11. If everything is ok you will see a green progress bar flashing. (I was stuck here with the "NON-HLOS.bin" file which you can see in the "Other NON-HLOS File" folder inside the rom which you download)
12. When the process complete in about 10 minutes you can remove the usb cable from your phone.
13. Now you have to do a veeeeeeeery long press and hold on your power button untill you feel the vibration and after that you will see the OPPO logo.
14. Leave it for 5-10 minutes to load the Color OS.
15. Ok you have a working phone but still some apps icons that are missing and the keyboard doesn't appear when you have to write something.
16. Download THIS zipped ROM and put it in the internal storage of your phone.
17. Shut down the phone then press and hold the volume - and the power button at the same time for a while intil you enter into recovery mode.
18. Choose english and then install rom from zip file. After the installation complete reboot the phone and you will get a working keyboard and few more apps like Browser, Chinese market and else....
For me i still need to insert the IMEI's because they are lost... and now i have message: Oppo nv backup. The NV partition is invalid...
Good luck to all! And if you want to give me a beer: paypal: [email protected]

No Recovery Mode - Flashing through Computer

Hi
I have an ASK 748SP tablet, model info "crane-evb v13" with Android 2.3.4 installed.
I have not had success with flashing a recovery mode.
My device is not on the ROM Manager list.
flash_image responds with "Error scanning partitions: No such file or directory."
The device was strangely rooted when I bought it from the retailer. The instruction manual strangely says to boot into recovery mode by holding Vol + and the power button. I called the support company and they said that a recovery needs to be installed first. Using Root Explorer there is no recovery folder. (/recovery) - is there supposed to be?
Sorry if all of that doesn't make sense. I'm a noob around here.
So my question is how can I flash a recovery mode on my device OR how do I flash a ROM via my computer? (and make backups.)
PS: I do not have fastboot and am hopeing to upgrade to ICS.
Any help would much be appreciated. Thanks.

Have you found anything out yet?
I purchased a 5 point capacative screen 7 inch tablet from Ebay (NEW) about 4 weeks ago. The name of this tablet is Tablet PC (LOL). But under About Device and model number I get the same crane-evb-v13, Android 2.3.4, Kernel Version 2.6.36-android. Other than a minor issues with a keyboard, a retarded partioning, and getting Netflix to stay in sync (voices and video out of sync) the unit has been fast, responsive, and over all good considering I paid $128 new for it.
Have you made any head way as to if this unit can be rooted?

My tablet surprisingly came rooted like I said, I have tried rerooting it but didn't succeed. Unfortunetly I have bricked my device but hope to recover it soon.
@I get the same crane-evb-v13, Android 2.3.4, Kernel Version 2.6.36-android
I have Android 2.3.4 too (or should I say I did, ) Kernal Version 2.6.36-android, and I too have minor issues with the keyboard.
Retarded partitioning - I think so too - once again - flash_image failed, I seem to have /mnt/sdcard instead of /sdcard. The sdcard is built in which kind of confuses me.
Thanks for your reply, hope you can get your device rooted. If you find anyway to install recovery mode, please tell me.

bricked huawei g730

hello there,
I have huawei g730-u10
"MTK6582, quadcore cortex A7, 1GB Ram, 4GB Rom"
last week, I was trying to install a CWM recovery using "mobile uncle" app. after it finished , a prompt for restarting appears and I pressed "yes".
it was the last time seeing my phone alive!!! it restarts to huawei logo for about 20 seconds and restarts again and again and again....
unfortunately my device doesn't have a rom online, even on HUAWEI website, so, I downloaded a similar phone ROM "hdc-s5-gold" to use its preloader, cache, boot , etc
the problem is when I connect the phone to SP flashtools the red bar appears and then it holds for seconds and a message with connection loss appears while the phone is going in its infinite restart.. so the flashtools seems to find the phone for a while but fails to write to it thanks to power loss.
notes:
1. I have tried many flashtool versions
2. I have tried with and without battery connection, and with and without volume up holding.
3. the phone can't access to CWM, download mode or factory reset mode.
4. the drivers are installed shows: "MT65xx preloader" and I think there is no driver problem
5. even when I connect the phone to charger, it keeps restarting and the charging logo doesn't appear
I appreciate any help

SP log files attached
thanks

I have same problem.How to solve it.

same problem, what to do???

Universal unbrick guide:
Terminology - types of bricks:
Soft brick - often occurs in the shape of a bootloop or any other problems with booting such as always getting to recovery or not getting past the carrier logo. This type of a brick, which shows some signs of life, can in most cases be fixed.
Hard brick - As the name implies, your phone can essentially used as a brick and it shows no signs of life. This kind of a brick is rare and in theory should be unfixable. However there are advanced methods of fixing your phones such as JTAG, but they require extra tools and accessories.
The decision:
Is my phone soft or hard bricked?
If you answer yes to all of the questions below you probably have a hard birck:
Test as said in order!
Nothing happenes when you hold or press the power button
You cannot get the screen to even turn on by pressing or holding any combination of buttons on your phone
Nothing happenes if you do the same as about but with your phone plugged into a charger
Nothing happenes when you plug your phone into a computer
When you plug in your phone into a computer it does not recognize it as a phone, storage or any other media device
Nothing happenes when you try all of the above again, but with removing the battery in between steps for 10 seconds and putting it back in again
Nothing happenes when you try all of the above again, but after leaving the phone plugged into a charger for 2 hours
If all of the questions are a "yes", then you either have a broken charging port and and a discharged battery or you have a hard brick.
The unbricking:
There are many methods of unbricking and they are all different to each phone. Here I will list the most common methods that often succeed.
Samsung users skip to 4. method.
1. If you have access to a stock recovery:
Method 1:
1. Shut down / turn off your phone.
2. Boot into Recovery mode – hold down the volume down button and then hold the power button (the button combination is different for every phone. Look yours up on Google)
3. Use volume keys to navigate the menus, and power button to select the menu items (Again, might be different for every phone)
4. Choose “Wipe Cache Partition”.
5. Choose “Wipe Data / Factory Reset” to delete all your settings and apps, using the correct ROM.
6. Reboot your device.
Method 2:
Download the stock rom for your phone. It should be in ".zip" format. Make sure it's the official version
(Find it by Googling something like "[your phone model] stock rom")
Put the file on your phone's external SD card.
Make sure that the rom is for your exact phone model.
1. Shut down / turn off your phone.
2. Boot into Recovery mode – hold down the volume down button and then hold the power button (the button combination is different for every phone. Look yours up on Google)
3. Use volume keys to navigate the menus, and power button to select the menu items (Again, might be different for every phone)
4. Select "apply update from external storage"
5. Navigate to the zip file you copied to your phone
6. Install it.
If you get Status Error 7 that means you didn't download an official stock rom.
2. If you have access to a custom recovery:
Method 1:
Try stock recovery method 1
Method 2:
1. Find a stable custom rom for your phone or if you want to download the stock rom
Make sure that the rom is for your exact phone model.
2.. Copy the zip file to the phone's external SD.
3. Install the zip
(If you have a custom recovery you probably know the drill)
3. If you have access to fastboot mode:
First install ADB and fastboot drivers (if you haven't already):
To install it on windows there is a handy tool called the 15 Second ADB installer which will install pretty much everything you need.
On Ubuntu install with:
Code:
sudo apt-get install android-tools-adb android-tools-fastboot
On Fedora:
Code:
sudo dnf install android-tools
On OS X using Homebrew:
Code:
brew install android-platform-tools
Once you have the drivers installed you have to find a recovery image for your phone to install a custom recovery.
You can try one of the popular recoveries such as CWM or TWRP.
You need to get the recoveryNameHere.img file for your phone.
Find it by Googling:
"[your phone model] TWRP recovery"
or
"[your phone model] CWM recovery"
Make sure that the recovery is for your exact phone model.
Now on your phone enter fastboot mode:
Turn your phone off.
You can try different button combinations. For my phone it's holding power and volume down buttons.
Once you're in fastboot mode plug your phone into a computer and open your terminal/cmd.
Type in:
Code:
fastboot devices
You should see a list of devices. There should be only one device ID number.
If you see the ID it's working. If you don't you didn't install the Google USB driver properly (on Windows) and if it says "'fastboot' is not a recognized command" or "No command 'fastboot' found" then you didn't even install your drivers.
If you have problems with installing Google "how to install adb and fastboot drivers"
Now that you know fastboot is working type in:
Code:
fastboot flash recovery C:\Path\To\Recovery.img
Replace "C:\Path\To\Recovery.img" with an actuall path of the recovery file you downloaded.
It should say success.
If it doesn't try to execute:
Code:
fastboot oem unlock
This will delete all data you had on your phone (games, game progress, apps...).
Now try
Code:
fastboot flash recovery C:\Path\To\Recovery.img
again.
Once you're done type in:
Code:
fastboot reboot
And your phone should still not work. Now what you have to do it try the custom recovery method above (number 2.)

HELP! ROM Manager bricked my O3D - Is it fixable?

NOTE: Before we start, I have now googled it and in hindsight I probably should of left RM alone!
Anyway as the title states my O3D seems totally goosed! I selected the recovery flash in ROM Manager for P920, it rebooted and all it does now is show the logo for a second, vibrate then off. I tried the usual tutorial stuff...
Power button, Vol up battery in - it comes up 'USB Device Unrecognised' and then It also keeps popping up 'Unknown Device' however when I click on properties every entry is 'Unavailable'
Power button, Vol Down, battery in does nothing (tried it a million times)
If I do...
Power button, Vol up then apply the battery - Device Manager finds... 'LG Mobile USB Modem', 'MAP SMS' (Other Devices) and 'LGE Mobile Composite USB Device'
No sign of OMAP44xx so the flash tools don't see it... strangely LG Mobile Support Tool sees the phone and tries to update it however it says it has the latest firmware, when I use the update recover option it gets to 15% but then complains that it can't communicate with the phone.
Is it dead? :crying:
Any help would be much appreciated.

dont worry. its not dead. has happened to my phone a trillion times ..
all you need to is try as below:
1. without connecting phone to usb first hold down 3d button then volume down and keep pressing power untill it starts up and then off again , then release all 3 together as it is off and repeat (remember first 3d then volume down and then power). this time just let the power button go on lg logo but keep pressing the other 2.
2. if this doesnt work, then easiest method - download omap4boot for optimus v1.21 or all in one p920 v1.3 by XDA, remove battery, only press down the volume up button and while pressing connect usb. make sure you hear 1 ding of connect , 1 dong of disconnect then 2 dings of connect. after this the ding dong should end .. if you have all drivers installed , then it will install omap drivers. a window will pop up and everything will have a green check. once it does that you can install a custom recovery twrp or cwm using fastboot . boot into recovery and flash a rom.
still if doesnt work, have patience, post a reply and will tell other steps to proceed with .....

Thanks for your time RVBSD, unfortunately (although I will keep trying!)
In No. 1 - I get the first logo, but when I re-apply the 3D/V and power, I don't get the second logo.
In No.2 - I get the first ding/dong then just 1 ding, no sign of Mr OMAP! - I'll keep trying though.

Once u get the second ding and then this music stops, Open device manager. Look for lg usb modem and disable it. Then look for omap44 something. The device manager may be refreshing quickly. Somehow i had a chance to right click on omap device and chose update driver. Select manual and choose omap.inf from the folder that u have to download as per my previous reply. Restart computer and check again.
Alternatively you can install all inf manually, right click and install, before connecting the device.
Let me know
Sent from my LG-P920 using xda app-developers app

Again, thanks again for your input but I am still no further. I manually clicked the inf and it said it installed fine... but nothing changed in Device Manager. I then attempted to 'force' the driver on the unknown device, however after it installed it returned a 'Code 10' error... unable to start.
Even tried the service software 'LGNPST' but it couldn't even connect to the port! ho-hum...

i tried it again. even on my computer it didnt take the omap drivers this time.... strange .....
but i could install fastboot, then installed cwm recovery . then flashed a rooted rom and its working ...
1. Turn off your Phone, pull out battery.
2. download omap4boot-for_optimus-v1.21 (run "start_fastboot.bat" (it will wait until phone connected)
3. connect phone with USB cable without battery, the usbboot will start
4. insert battery while the usbboot is waiting, it gives 5 secs only
5. unplug USB cable the LG logo will appear with fastboot on top
6. download the attached files to your desktop and extract
7. open cmd and in cmd navigate to fastboot.exe location, where ever downloaded
8. run fastboot.exe from cmd and choose the cwm file to be pushed to your phone
command : fastboot -s flash recovery recovery-clockwork-6.0.1.9-p920.img
9. reboot device into recovery , try to wipe cache and factory reset and try to reboot
if this works it will take you to existing installed rom, then you can reboot to recovery and flash Su_Bbox_1.20.2_gazhead_signed.zip to root it
10. else copy a custom rom to sd card , insert in the mobile , reboot into recovery and flash the cutom rom

PLease help
CAn you tell me how can mount recovery partition

Bricked my Mate 8 when trying to go from NXT-L29C636B180 to NXT-L29C636B211

Hello everybody,
I managed to brick my mate 8 as per the title, honestly thinking why did i even bother, that whole saying "If it ain't broke, don't fix it." applies here 100%.
So i have been in the NXT-L29C636B180 which i put with the dload method (original was C636B103) and since then everything was good, all except the video camera that is.
So i wanted to try to get to the nougat update (561?) but i read that you need the 211 first. As i couldn't find it i used the android app: firmware finder, and using the proxy method i told basically the system that a new update is up and download it - so this is the update option in the settings..
So after it downloaded NXT-L29C636B211 then it restarted, starting unpacking, and the installation stopped at around 5% when it restarted by it self. And that was it...
I am in a screen where i cannot use the touch, but only the buttons on the side and have the options
"Reboot system now"
"Wipe data/ factory reset"
"Wipe cache partition"
Tried the cache and rebooting, didn't do anything.
Tried wiping, and reboot, then i go in another page
"Huawei eRecovery" where it asks to connect to the wifi and download but then throws an error message "Getting package info failed"
That is pretty much it, i tried putting the update.app in the dload folder in the sd card and tried to use that method but it wouldnt boot that (used the volume + and - and power buttons) but it took me back to one of the above.
Am i out of hope? Is there anything i can do to restore it?
I really appreciate the help.

same problem!

That happened to me too. you will still be able to enter fastboot. plug your phone to your pc and and press and hold the power and volume down. that should take you to the fastboot screen.
find the appropriate twrp recovery for your phone and use the command
fastboot flash recovery "recovery name".img. wait till its done.
press and hold the power and volume down button till the phone reboots. that will takeyou to twrp recovery. there you could either flash b210 or the beta b521 -- which i am on.

Thank you for the response. I will give it a try today after work i am a complete noob so its the first time for me to see what fastboot is, never heard of TWRP, i was always stock so never needed to mess with my phones.
If i recall doing power and volume down while plugged it was taking me to the page i mentioned to wipe the data, reboot or wipe the cache.
I managed to go to the fastboot page on the phone by pressing volume - and then plugging the phone to the pc. Now in the white page on the phone it shows, Phone unlocked in red. Does this mean just it is carrier unlocked?
So do i need to have the bootloader unlocked to do anything here? How do i do that? I cannot buy the code i suppose now since my phone is bricked i will have to go the Huawei way? And how do i do that, i saw a site to create a HUawei ID but in the registration page it didn't mention UK anywhere (where i live), mentioned Hong Kong and other Asian territories. I bought the phone from Wonda mobile, and being the 636 i would think its the asian model anyway.
Regarding TWRP, i didnt install it from before the phone was bricked will i still be able to do what you mentioned? And for the image i need to use, do i need to go to the firmware i was in before (636B180) or the one i tried to go to (636B211)? I can't seem to find the 180 anymore anywhere.
Sorry for the mass amount of questions, trying to sort it i have the phone for less than a year and i am gutted for messing it up like that.

Unbricking HTC U12+

Hey guys - I hope you're doing well.
I recently got an HTC U12+, but wanted to try using a custom ROM due to all of the bloatware . Unfortunately I think I've ended up bricking my device. Here are some things I've since tried:
- Restoring to the backup I made beforehand in TWRP - restore works without any errors, but then just hangs at the boot screen
- Method 1 from this thread (https://forum.xda-developers.com/u12-plus/how-to/collection-htcu-u12-ruu-firmware-t3794664) - TWRP always says the zip files are corrupted for some reason
- Method 3 from that same thread - this actually worked before, but I tried installing a custom ROM again, somehow messed up again, and now this method no longer works as it just hangs at the "HTC" boot screen for eternity
- Both methods in this thread (https://www.theandroidsoul.com/how-to-install-htc-firmware-ruu-and-zip/) - the first one leads to a "failed remote 99 ru unknown fail terrible mishap" error, and for some reason my PC doesn't see my phone when I try the second despite being able to see it in file manager
- Probably many other methods that I've now forgotten
I know this is a whole lot of information, but I'm in desperate need of some help. I typically like to troubleshoot things myself, but I've been trying to fix this for quite some time now and could definitely use another set of (much more experienced) eyes. I greatly appreciate any help you guys can provide.
Thanks.

Flash RUU with SD card method
Download RUU from here(important:check your CID): https://docs.google.com/spreadsheets/d/1wIRrVQawd5rD-t9VKPQ-SdRK20RcJVZhwD7lhmPIK8w/edit#gid=0
1. rename RUU to 2Q55IMG.zip
2. copy zip in the root of your sd card. - external card / not internal - it will not work
3. reboot to download mode,
4. your device will pick up the zip file and flash it.
5.follow on screen instructions and enjoy your RUU(this method erase all your data)

I'm having an issue with my u12+ where it just continually reboots to a message saying "The boot loader is unlocked and the software integrity cannot be guaranteed. Any data stored on the device maybe available to attackers, do not store sensitive data on this device" and then it shows the white HTC logo that says Powered by Android down the bottom of the screen, it stays like that for about 5 minutes and then reboots and does the same thing over again.
Holding the power down button does nothing, it will not turn off the phone. Holding power and volume down does nothing either. The phone just does this every 6 minutes and reboots and cycle and that's it.
I've tried putting the file 2Q55IMG_IMAGINE_DUGL_O80_SENSE10GP_hTC_Asia_TW_1.53.709.1_Radio_sdm845-000201b-1807311356_release_531499_signed_2_4.zip (renamed to 2Q55IMG.zip) on the root of a 8gb Fat32 formatted SD card, but I just can't get into recovery or download mode.
I've tried holding down all 3 side buttons for minutes, or just the power button, or combination of buttons, they all do nothing to the phone. (it's as tho they are disabled, but sometimes holding a combination of the 3 will make the phone vibrate a little bit, but in no particular time or order)
When the phone is in either state (locked bootloader message or white HTC logo) my Windows 10 PC sees the phone plugged in as a "USB Input Device", not an Android Phone or Android Device. So using ADB or Fastboot commands do not work to it. I've tried to force the driver to the HTC driver but that does not work.
I also tried using the RUU_IMAGINE_UHL_O80_SENSE10GP_NA_Gen_Unlock_1.30.617.2.exe file, but once again it doesn't detect my phone.
Any help would be kindly appreciated.
Cheers!
EDIT: So I was finally able to get into download mode by waiting until the phone done its 6 minute reboot and then holding power down until it vibrated once, then held volume up until it vibrated again, then let go of the power button, I was then able to choose recovery, download etc.
So I managed to get the file 2Q55IMG.zip to install, it said it installed 100% okay. The phone rebooted and now I'm stuck again just at the white HTC logo and Power by Android down the bottom of the screen.
This time the phone is not automatically rebooting itself and no key combinations will make it reboot. I've tried holding them all in certain combinations for periods of time, the phone will not reboot or turn off.
EDIT 2: So maybe I didn't wait long enough after installing the 2Q55IMG.zip file, I finally got the phone to reboot and now I've got a working phone again. happy days :laugh:

with the phone off, turn it on,when you feel first vibration
quick release power key and keep push volume down.
Smartphone should boot in bootloader mode.
can you get into this mode with this guide?

Cheer mates, issue sorted. I just updated my comment in my post.
Not sure if I'm game enough again now to try and put LeeDrOiD and Magisk on it.
