Missing Boot loader and operating system... - Android Q&A, Help & Troubleshooting

Hello all, i recently picked up a ulefone armor 2s and i was attempting to root it and i have made a mistake and now i don't know what to do as the phone is in a bricked state at the moment.
I followed the guide here
https://forum.xda-developers.com/android/development/root-ulefone-armor-2-easy-rooting-t3780055
and have got nothing as TWRP did not load on to the device properly and i am stuck in a boot loop. i am thinking that somehow i made a big mistake and deleted the recovery somehow and i am unsure on how to load a recovery back on.. I have rooted phones before so i have a basic understanding of ow it works but i dont know how to fix this...
Please Help and thank you for helping

Try using pc.. if its still detected by the system..
If yes check the processor of your ulephone if its mediatek or qualcomm. If its MTK use sp flash tools else use qualcomm flash tools.
Even if the bootloader is missing, its the preloader that will be there. And flash tools are the way they can make use of preloader. Make sure you have proper drivers installed in your system.
If you have a working recovery, install it via flash tools so the device can rise from the dead..

Thank you for this, I got the device back up and running... But I'm missing a bootloader now. Any thoughts on how to flash it?

[Q] Bootloader and everything erased Lenovo A760

Hi,
I have screwed with my smartphone (a Lenovo A760)...
I want to install a new rom and decided to erase everything.
I goes into clockworkmod / storage and format each point like /system, /boot...something, etc.
Of course, my phone won't boot anymore.
Is there a way to re-install a bootloader and a rom?
Thank you so much for helping me and sorry for my english, I speak french.
Cheers

Hi,
I've just read the 27 pages of this post, but there's no answer to my question.
ADB can't find any devices.
When I connect the phone with USB, Windows detects an unknown device, I try to install QC_Dload_driver.zip found in The lenove a706 thread.
Now Windows detects a "Lenovo HS-USB QDLoader 9008 (COM16)"
ADB can't attached my device.
My gsm is turned off and no manip like volume+ + on/off works, it stays off
What can I do?
Thank you

You need to have an insecure boot image. Unpack your boot image with either of these tools: michfood (for windows) or bgcngm (for linux/cygwin). Add the following lines in the default.prop of ramdisk folder
Code:
ro.secure=0
ro.debuggable=1
persist.service.adb.enable=1
Then repack your boot image.

Do you know how can I inject the new boot.img?
ADB won't detect my device.
When I run adb devices, I receive an empty list
When I run adb usb or anything it says : error device not found
My Windows 7 detect my GSM as a COM port (Lenovo HS-USB QDLoader 9008 (COM17)) after install QC_Dload_driver.
One more, thank you

You need to flash it via SPFT, download links are here and on how to use that tool. It's the most important tool for any MTK devices.
But you need to find the correct scatter.txt file for your device to be able to use SPFT and flash the modded boot.img, otherwise, SPFT won't work properly.
EDIT: Why not just look for a flashable stock rom for your phone? Since you already have CWM/custom recovery, you can just flash that rom and your phone will be up and running.

My phone is not a Mediatek device.
It's an Qualcomm MSM8225Q Quad Core 1.2GHz
Do you know if I can use SPFT for those Qualcomm CPU?
Thank you for the time you spend to answer

I see, nope, you can't use SPFT. It's only for MTK devices.

[Q] XOLO Q500 Bricked. Qualcomm Snapdragon MSM8225Q device.

Hello guys, there is no specific forum for this device, that is why have started this new thread.
My xolo q500 is bricked. It stucks at the logo and doesn't go further. I was trying to install CWM recovery. But niether CWM nor TWRP not available for my device so i tried to flash CWM of some other device from the rom manager. It was of xolo q700. After flashing my device got shut down but stcuked at the boot logo when restarting.
All i wanted to do is to flash a custom rom. I rooted. I tried to flash it via the default recovery but it was not succesfull i dont know why. I googled and came up to know that i need to install custom recovery like CWM or TWRP to successfully flash custom roms. So when i flashed cwm of xolo q700, this happened....... It was all because of that other device's CWM..... and that recovery.img file was placed in the internal memory. So overall, i flashed it from the internal memory.............
Now my phone niether boots up normally nor boots in the recovery menu. It stucks at the xolo logo. I googled but i found unbricking methods for mediatek devices via sp flash tools but my device has Qualcomm Snapdragon chipset , so that didn't worked. Please help me how can i unbrick my device? Is there any method to unbrick qualcomm based devices?
I had that thought of not installing stuff of another device. But i niether found any custom rom nor recovery for this device. So i decided to just use another device's stuff. Yeah i know that totally crazy idea... but.....whatever when i plug it into PC it does not detect anything but when i plug it in pc after removing battery, its LED starts blinking. When this happened first time... Something like 'Qualcomm msm' was installed but nothing thereafter......

Unbrick Umi Iron via Stock Recovery?

I used SP Flash Tool to update the ROM of my Umi Iron (deselected preloader, as advised), it stopped at 18%, gave an error and since then, my phone is in a bootloop. Can only get to stock Recovery (the android on its back). After a while in recovery, the phone reboots automatically, showing the Umi symbol for a few seconds, rebooting again back to recovery...
Fastboot and adb don't seem to find the device in this state. Installed the MT65x3 USB VCOM drivers, anything else I need?
Anyway to enter the bootloader or use adb/fastboot in any way? Sure hope I'm not completely screwed...

[Help] Archos 50d Helium got Brick! Pls!

My Archos 50d Helium have got brick after I flash TRWP recovery (maybe wrong version for my phone). Now it can't get into logo, recovery mode, fastboot mode. It can be realized via PC by Qualcomm HS-USB Diagnostics 9006 Drivers. There is any method to recover it? Thanks so much!
Ps: Sorry about my bad English!
Today I found a method to fix it. I guess it bricked due to TWRP format wrong to SYS_BOOT partition on my device (my fault ).
I need a SYS_BOOT.IMG or some thing like that on that partition to unbrick it.
PLS help me!
I'm not sure about Helium 50d... but you should check NeedRom anyway.
They provide their files in .pac format, so you kinda have to use their software (it's free and I didn't see any issues) to find the file location inside. Navigate to the location and it should have the .img file at that location. It basically extracts it into a temp directory and you just have to go find it.
Once you've done that then it's a case of using ADB or Fastboot to flash it over. Not sure if you can use the program itself, it's possible. Unfortunately, it's buggy on Linux so...

Could someone make a TWRP and a stock android version for the Blu Pure XR

I would like to know if someone could make a custom recovery and a stock version of android that I could put on my Blu Pure XR. I don't care if get rid of the 3d Touch on the phone. I just would like to have the stock android interface again and probably also the ram management will be better on the stock version.
I have the same request, would love to see TWRP. I'd like to install pixel launcher as system app and remove the adsup fota spyware.
The Pure XR is otherwise a great phone. Power management on stock is fantastic, i can get 6-7 hours of screen on time.
The Pure XR is essentially a Gionee S8 but sadly I dont see any custom recovery or development interest for that either.
Include me as well. Thanks
So the Pure XR is similar/same to the Symphony Helio S20...
There's a thread here that has a working twrp: https://forum.xda-developers.com/android/general/how-to-root-symphony-helio-s20-t3491123
I tested the recovery.img by loading it with fastboot without flashing and it worked!
You'll need adb/fastboot and the drivers first. Then boot the phone into fastboot mode by holding power + Up keys.
Select fastboot. After that, run: fasboot devices to make sure your phone is detected. Once detected:
fastboot oem unlock
reboot the phone, it'll do a force wipe
hold power+up keys again and boot to fastboot mode
Now, run this on your PC: fastboot boot recovery.img
Once the image is transferred, the screen goes blank...wait a min or two and TWRP will show up.

When I connect the phone through Fastboot and enter the command "fastboot devices," the phone is never recognized. I'm using Windows 10. Any help would be appreciated.
I used Linux instead. Have you installed the mtk and adb windows drivers?

Yes, I installed the mtk and adb drivers however while adb works and detects my phone, fastboot does not.
Ok, I attempted using the SP Flash Tool on Windows 10 and successfully installed TWRP and rooted the phone. The only flaws are that the phone takes a few minutes to load into TWRP and unfortunately, there are still no custom roms on the device. It is a good start however.

Hey bud, big favor, would you describe step by step the rooting process, I used SP Flash Tool on windows 7 to install TWRP and it gave the ok check marK, then I tried to boot into recovery and I found out that TWRP was not installed. Do you have to unlock the bootloader to be able to install TWRP using SP Flash Tool? Thanks in advance.

Hello everyone, I need your help, I've been trying to unlock my bootloader to root my phone, under setings I have developer options-OEM UNLOCK, but I only get as far as FASTBOOT MODE using my laptop as well as my pc, I tried this process with Windows 10, Windows 7 and latest Ubuntu. I tried different data cables, different usb ports 2.0 and 3.0 and nothing seems to work, I can put the phone on FASTBOOT MODE with my pc or lap, but then after that it looks to me that there is no comunication between my pc and phone. I installed all drivers several times and under DEVICE MANAGER everything looks good, as far as data cables I'm using 2 blu original data cables as well as aftermarket ones. Any help will be appreciated. Thanks in advance and have a good day.

I remember something similar to this happening to me when I used a different version of SP Flash tool. Try SP Flash Tool v5.1624.00.000. After this make sure you have the scatter file for the MT6755 as well as the recovery file for the phone. Make sure that you have selected the scatter file for the phone and that the recovery.img is in the same directory as the scatter file.
Once this is done, make sure that you have installed the preloader or VCOM driver for the phone. This is tricky as the opportunity to apply the correct driver comes when you are powering on the phone and in this time you must click on the device that pops up in this time, right click it, and click properties.
Once this is done, go back to SP Flash Tool and click download, your phone must be off and unplugged before doing this. Then after this step, plug in your phone and the download process should begin (this might take a while). After this, boot into recovery mode which also will take around 3-5 minutes maybe more. After this you will have TWRP installed and from there you can install various apps including SU.

Thank you very much, I'm gonna give it a try as soon as I get a chance, I'll report back. Thanks again.

Hi everyone, TWRP has been released by lopestom here https://forum.xda-developers.com/pure-xr/development/twrp-twrp-3-1-x-x-blu-pure-xr-p0030-t3623865
Since the Pure XR threads are very slim here I thought I'd post this here.
Seems my XR's data has got very slow, signal strength weak, etc.
Trying to figure out if this is Cricket or something up with the phone. My wife has a Blu Life one X3 and the same Cricket and her signal and data speeds are always better than mine.
What are some things to check/look for? I've tried a few like manually choosing the Network, changing the APN settings, etc.
Any further advice would be greatly appreciated.
