What is eboot error 14009?

I want to flash CWM with the sp flash tool 2.x but it always stop in the middle of the progress bar and it gives me an eboot error 14009? I have already rooted my device and I'm 100% my usb driver is working but I couln't find a proper cwm update.zip file but only for the MMX A52 which is a clone. My device is a Pioneer Gionee GN100 and I couldn't find any official cwm update.zip.
Update: I've tried adb and fastboot to no avail. I think my device doesn't support fastboot.

[Q] Lenovo P780 Boot loop help pls!

Hi all.
I guess I am in deep trouble.
I have a Lenovo P780 (chinese base rom) 4gb version. Rooted it and installed with CWM recovery for P780. Installed Muse UI 3.0 custom rom from custom recovery via sd card. Swapped the internal SD with External SD card by editing the vold.fstab and vold.fstab.nand also.
However, I realised that there are a lot of bloatwares that took up the RAM and started uninstalling chinese apps that seems to come with the custom rom from system. However, when I restarted the phone, its now unable to boot beyond the 1st boot screen. (Boot loop)
Current state of the phone now:
1. Able to enter custom recovery mode, but menu is blank except for the navigation commands. (return, up, down, confirm)
2. Able to enter adb only when the phone is in custom recovery mode.
3. Able to connect to PC (Windows 7 64bit). Mediatek MT6589 usb drivers installed. Many versions of sp flash tools installed and tried.
4. Can't seem to enter fastboot for this phone. (Tried many key combinations. Only Meta mode, recovery mode and factory mode are found)
Things I had tried:
1. Flashing stock rom.
I had downloaded the stock roms and tried flashing with sp flash tools, but I always encounter the following errors. Had also tried switching to another windows XP based pc and still encounter these errors.
(a) Firmware -> upgrade. Tried Auto Format Flash also and it returns with the same errors.
- BROM ERROR: S_FT_FORMAT_FAILED (4010)
Format flash error. Possibly given wrong format range. Please check your format settings.
(b) Download (all img boxes checked)
- BROM ERROR: S_FT_DOWNLOAD_FAIL (4008)
Download to flash fail!
(c) Download (only one img checkbox ticked, tried system.img and recovery.img)
- - BROM ERROR: S_FT_DOWNLOAD_FAIL (4008)
Download to flash fail!
2. Flashing recovery from adb terminal via windows and usb connection
When I put the phone to the custom recovery (with missing menu options), the adb terminal is able to recognise the phone and returns the following after the command 'adb devices':
0123456789ABCDEF recovery
Upon entering the shell via 'adb shell', I am given the # sign. (already in SU mode?)
Tried to flash a recovery image from this mode via terminal command flash_image, but encounters the following problems:
(a) unable to mount/remount
- mount -o remount rw /system
mount: mounting rw on /system failed: Invalid argument
chmod 777 /system/flash_image
# flash_image recovery /sdcard/recovery.img
no response from the terminal after this command.
I had tried and tried these for more than a week after work, but had not been successful in reviving this phone. Appreciate if anyone can assist me as I had ran out of ideas already.... Please assist me in reviving this good phone. Many Thanks!

Yep. Tried using several versions of the drivers downloaded from different places and used USBDeview to remove/reinstall them. The error still comes back and haunt me.
maybe this can help you
No luck.... formatting is not working in sp flash tool (4010 error) and the preloader in the thread is not for my phone.....
Anyone able to help pls....?

have you use google my brother ? google is our true friend.
but i glad if i can help you:angel:
you can visit this for factory rom
or you can visit lenovo forum
or you can go to needrom
Yeah. Google had been my fren, but no more after googling for 2 weeks without a solution. Trust me. I had looked thru most solutions found in google and had tried without any success before I post here.
All those stock roms of all release numbers I had already tried as mentioned above, with sp flash tools (tried many versions of that also.) ALL attempts are stucked with the errors mentioned above. The sp flashtool simply just fills the red status bar, and stopped with one of the errors in my 1st post.
I've even checked the chinese forums. My situation seems to be this:
The partition table of the flash memory had been reformatted thanks to the custom rom flashed via sd card. That's why it always returns a format flash error when I attempt to flash back to the stock rom which uses a different format range using sp flash tools. The only way out is to do a clean format of the flash memory. But I haven't find a way to do that via sp flash tool or mtk droid tool.
My only recourse is on of the following:
1. If I can restore the custom recovery (via adb in recovery mode(no fastboot) or meta mode) and make it workable to do another sd card flash with a custom rom. I have no idea why the options in my custom recovery went missing. It was working before I flashed the custom rom. I guess that accursed rom somehow erased my custom recovery during boot.
2. If I can somehow be able to do a complete flash format with the correct format parameters using some tools. Sp flash tools had failed me so far.
Anyone is able to help in these directions? Many thanks....
The sp flash tool log also have this line when I searched for 'Errors'

I think it's because the driver is not installed, try to disable digital signature on your windows, and reinstall driver for your phone
for how to disable digital signature go to this

Already tried this. I had tried on 2 pcs. Windows 7 and windows xp (no digital signature). Same errors occur in both pcs. I really don't know what is going on with this phone. Nothing seems to work.
PS: Have been running the program as administrator all along also.
Sent to a phone repair shop and its at worst state than before now. Unable to power on. Connecting phone to computer and tried using sp flashtool now gives 4032 error (Enable Dram failed).
Any hope with reviving this phone now?

Hi, first, do you have SP Flash Tool installed on your PC and have the drivers installed? If yes, download the stock ROM of your choice from here and flash it with via SP Flash Tool, and your phone should be revived.
Flashing methods are clearly stated in case if you don't know how to do it.

Samsung A5 2016 signature verification failed

Hi guys,
I have some issues here.
I have A5 that is stuck at Samsung loading screen.
I want to install new ROM.
If I boot in download mode abd failed to detect it although lsusb see it (I have linux).
If I boot in custom recovery menu and choose option apply update from SDcard, it says Signature Verification Failed.
There is no option to disable this verification in samsung menu.
Also if I choose update from adb, abd recognise it, buy the same issue with sideload: Signature verification failed.
What options remains here?
I want to close the thread.
Thanks

Soft-bricked huawey lyo-l01

Hi everyone, as the title says, my lyo-l01 is soft-bricked. I searched everywhere online to find the UPDATE.APP file and an official ota package...my actual build is lyo-l01c600b105, and the most close firmware I could find is c600b103. Now, this file has an UPDATE.APP file, but also a scatter file and full SYSTEM, BOOT, RECOVERY etc...imgs. I already have huawei update extractor, mtk droid studio, huawei multi-tool, mtk rom studio and sp flash tool installed on my pc.
Unfortunately multi tool won't work because I have an unlocked bootloader but a frp lock, which I tried to unlock via adb and fastboot but no success (I even tried to relock the bootloaader but it won't allow me to, because of the frp). I also tried using sp flash tool with the scatter file I have, but when I select it the tool gets an error saying "this application has requested the Runtime to terminate it in a unusual way. Please contact the application's support team for more information."
Mtk droid studio only recognizes the processor (MT6735), build date UTC (19700101-000000) and LCD driver IC: 1-ili9881c_dsi_vdo_txd (I really don't know what this is); and on start it says: "--- ERRORE : --- TotalBytesPerChunk Not Found. Set default Page/Spare=2048/64 !!!" and "--- WARNING! Recovery is not compatible with this device!". The recovery is a TWRP 3.0.2.
I was forgetting that I also tried to create a dload folder on the sd card and putting in it the UPDATE.APP file, but when pressing vol up + vol down + power my phone will boot into recovery.
So, summarizing:
- BUILD: lyo-l01c600b105
- PROCESSOR: MediaTek MT6735P
- Unable to boot to system, only recovery and fastboot (sideload too)
- Unable to relock bootloader, unlock frp, unbrick via above mentioned methods
Can someone please help me? I'm stuck from 3-4 days and I really need this phone back
Thanks in advance for any help!

unbrick Lenovo tab M10 plus (x606x)

Hello everybody,
first of all I'm, sorry for my newbie's awkwardness and for my bad english too...
I'm a linux (Debian) enthusiast and I'd liked to install it on my Lenovo Tab M10 Plus; my choice felt on "Linux Deploy" but it needs a rooted device so, after an internet search for tutorials and tips and a system backup (.adb file saved on PC) I bravely tried with Magisk... and I failed (or I think so).
The tablet start in a never-end booting loop and on the splash screen appears the message
"
Orange State
Your device has been unlocked and can't be trusted
You device will boot in 5 seconds
"
I can access in fastboot mode so I tried to flash a no-rooted (downloaded) boot.img but it didn't works (the flashing process reports OKAY but the device reboot anyway in Orange Status), I tried with the flashall command that reports
"
error: ANDROID_PRODUCT_OUT not set
"
I tried to wipe and flash but it didn't works, I granted the access in some recovery mode and tried to install the .adb backup file from the SD card but the system says :
"
E: signature verification failed
E: error: 21
Installation aborted.
"
I thought to open the backup .adb file for extract the original files (I don't know if it could be done and if it could be useful) but how?
I think someday someone more skilled than me will solve the problem but, waiting for that day... any advice ?
Thanks, anyway.
Cheers, Ste.
Use official Lenovo Rescue and Smart Assistant
Same problem...lenovo tab x606F firmware is not present in Lenovo Rescue Smart Assistant and you can't add it manually!
Yes hello, sadly I am having the same issue as well. Anyone have any ideas? Here's what I've tried:
