Could not do normal boot. Invalid KERNEL LENGTH. - Samsung Galaxy Note 9 Questions & Answers

This message I get when I try to power up my Note 9 N960F/DS.
I got it this way: Been running the same ROM for 2 years. Time to upgrade. Upgraded TWRP via the app. After downloading the ROM image to SD card, I tapped an app called Reboot, with the Recovery option. I suspect this app is from some old installation, and ended up on this unit via data restore. Now all I get is this message on a black screen. No logo, nothing. Message flashes once. If I plug into PC, message flashes repeatedly. Cannot boot to recovery using Vol-+Pwr, Vol++Pwr ineffective.
I suspect I bricked the phone, but I seem to remember once breaking out of this 2 years back, I think. Any ideas, clues, anything?

Try this, power off phone. Press volume up and bixby button and while pressing buttons insert data cable, phone should go to downlaod mode. OPen odin and flash stock firmware.

OK, tried it, display showed the same message until I released the buttons, then flashed the message every 4 seconds until disconnected.

OK, got it into download mode, reflashed twrp, now it's in a boot loop. Will continue working this.

It took a few tries, but I not only got everything working, I restored my data backup and upgraded to Android 10. Thanks all!

[q] galaxy s tweak app froze my phone

my phone has been frozen at the samsung i9000 screen ever since opening this app.... i am very new to this do not understand most concepts here.. ie. flashing a rom. If anyone can help me get my phone out of this state or has any suggestions on how i should fix this please comment.
if you can get into recovery mode try flasing another rom via cwm or flash it using odin and download mode (flashing non wipe roms via cwm might leave your apps and data intact)
What is the full name of the app? How did you try using it? Do you know what firmware version your phone is on?
First thing to try is turn off, remove battery sim and any microSD. leave five minutes and put all back in and turn on.

the app is galaxy s tweaks or something very simalar (black and white logo) the two options i was given in the app were "YES-BREAAAAK my phone" and "NO- Im not crazy" i selected no and then my phone just reset and wouldnt turn on again ive tried everything i can do without hooking up to a comp ( as far as i know) but thx for the advice
Where did you get this from? It does not seem to be in the market.
OK just found it. Have a read off all the comments. Not good.
http://www.appbrain.com/app/gst-(galaxy-s-tweaker)/com.pommedeterresautee.lagfix
You could try restart holding Home Vol up and Power button then choose Clear cache and Factory reset.
or
Try restart the phone holding home Vol down and press power button to get into recovery mode. then plug in and open Kies go to tools and firmware recovery.

Is telling me i need recovery code, I have never received one.
Just read this so it may work for you.
disconnect the phone from USB, pull the battery, replace it, boot into recovery mode and reconnect the phone. Go back to Kies and tools firmware recovery.
In other words repeat what you have done :-s
Original post on Android Forums.
The message indicated that I would need a recovery code that could be obtained later by clicking Tools | Firmware Emergency Recovery Menu.
I was then instructed to disconnect the phone, pull the battery, boot into recovery mode and reconnect the phone which I did. The phone would not reconnect. At this point I called Samsung tech support and wasn't impressed when I was simply told to repeat the procedure. But to my surprise, the upgrade was successful the second time around. Go figure! Anyway, I was wondering if anyone else ran into the recovery code message.

Have you been able to get in to recovery before?
Pull out the battery, put it back in and then press power while holding the volume up key. Let go of power button like 2 or 3 seconds after the logo pops up. You might have to try it a few times to get it right.

The best I can do is get the menu to pop up, but when I try to use it the screen goes blank. Press the power button again and the menu comes back.
Is there any way to wipe data with odin?

phone is bricked help please

i was planning on flashing a custom rom on my galaxy s6 today but at work i watched a video on how to get twrp recovery, so i downloaded it on to my phone, followed every direction and step using flashify then when i installed twrp and rebooted my phone it got stuck at the boot load screen, i cant even go to recovery mode nor download mode, everytime i hold the power button and volume rockers it just cuts off and boots back to boot loop cuts off boot loop and so on, idk what to do can someone please help
Slow down, take your time. This is not a permi-brick. Just go back, start at step 1, and try again. There is hope. There must be a way to get into recovery.
I'm having the same exact issue, I'm able to get into download mode by holding volume up, home and power buttons. I'm downloading the stock firmware now and I'm going to try to flash it with odin to see if it works.

If you two can't get into download mode for whatever reason get odin to the point it says waiting for phone or connection or whatever it says then let it boot loop a couple times with the phone plugged in (preferably start from a powered off state). This might just have been lg but for some reason I remember odin rebooting my phone into download mode if the program was at that point.
*edit*
I feel like I wasn't clear enough. You want the tar ball loaded and hit start before you plug the phone in. I could be way off but it's worth a try.

Bricked Huawei P9

Hello,
after a couple of attempts at installing TWRP recovery, some successful, some not, a ROM reinstall and finally this last factory reset, my Huawei P9 phone is stuck at what appears to be boot or restart loop. It is interesting however that I am unable to turn off the phone at all and it's been like this for an hour. At first, TWRP recovery wouldn't boot but the OS would. Then I did factory reset and phone restarted. Since then it won't boot or turn off. When I hold the power button to turn it off, it vibrates once, then vibrates again and then Huawei logo is displayed. After that a message that says "Your device has been unlocked and can't be trusted." & "Your device is booting now..." which is normal since I unlocked my phone bootloader, but the problem is that it is just stuck there.
It stays there forever, screen on, phone on, can't restart because it comes back to the same point, can't turn it off since battery is impossible to take out... Any hope? I bought the phone a couple of days ago and this is really bad... Help!
Edit: In case someone else stumbles upon similar situation - after trying everything possible with these 3 buttons I had available (vol+- and power), I have managed to boot by (I THINK) holding the power button for 10 secs but releasing it really fast after the screen turns off and BEFORE the first vibration happens.
Edit 2: Now I have the same problem again and I can't seem to get the right button "combo" to pass the booting phase like I did some hour ago... Any ideas?
Edit 3: It appears that the ROM I have flashed caused problems with TWRP - after I got an SD card, managed to put stock ROM (http://forum.xda-developers.com/p9/development/stock-rom-dload-file-p9-eva-l09-b136-t3382818) on it and then did force upgrade, the phone booted successfully.
Step by step:
1) Drained battery to 0% and forced phone to turn off (otherwise it would vibrate twice and get stuck loading TWRP if I tried to turn it off using power button)
2) When I plugged it in and it got some battery power it started, avoided TWRP and regularly booted the OS (which was causing problems with TWRP in my case I think). If you don't have any OS, do not recharge or turn on your phone until you have prepared and put SD card into the phone
3) Downloaded and extracted the dload folder from the P9 stock ROM archive (http://forum.xda-developers.com/p9/development/stock-rom-dload-file-p9-eva-l09-b136-t3382818) to root directory of SD card
4) Unplugged and turned off the phone using OS Shutdown option
5) Turned it on by holding power, volup and voldown buttons together - "Your device has been unlocked and can't be trusted. Your device is booting now..." message appeared so I thought it was stuck again and was about to hang myself, but then the OS upgrade started (if it doesn't work right away, try restarting the phone with power, volup and voldown buttons held together again)
6) Upgrade was successful but the phone wouldn't boot without complete factory reset, after which it booted normally. Bootloader was relocked, then I updated to the latest stable EMUI (4.1.1) and life returned to normal.
BUMP
I can access Fastboot&Rescue mode and use abd (but phone is not rooted). Other than that I can't get to repeat what I did when I managed to boot the phone previous time this happened some hours ago... Can anyone post all volume+- and power key combinations which I can try?
Any other ideas more than welcome...
Guys can someone help with this. I'm having the same sort of issues. I have flashed an update and now I have lost touch on the screen. I can't even use twrp because the touch is not working.
Please can someone advise.

After getting an SD card (everything I did so far was using internal storage) and putting stock Huawei P9 ROM on it (Android 6 and EMUI 4), then shutting down (forced by draining battery) and doing force upgrade (vol+ and vol- held after power up) I have managed to (upgrade and) boot my phone and get it back to normal again. If anyone needs more detailed explanation on how I solved this, feel free to ask.
Open bootloader again, i had the same problem few days ago
Yes please vernicht. My touchscreen has stopped responding after flashing an update.app using DC Phoenix.
I really need to get the phone back to normal.
Thanks in advance

Can you boot into OS? Please provide more exact details.
How I got out of the TWRP(?) boot loop: I couldn't take out the battery, but I have managed to drain it to 0% by letting the phone stay on for hours thus eventually shutting itself down. After that I have charged it and then powered it up. It didn't attempt to boot TWRP (no loop) but instead booted back the OS. After that I could regularly restart the phone and do all operations without getting stuck in loop, which allowed me to issue force upgrade command using hardware power up/down buttons.
Nope. I manage to flash it with DC Phoenix fully but it just keeps boot looping and going back to the Huawei logo. Then after that if goes into its recovery menu and the only my to use the menus is with the volume keys.

Are you able to put files on your SD card? If yes, you can try putting stock ROM on it and then force force upgrading (hold vol+ and vol- together after power up). It should overwrite everything and boot up.
I have done this but it won't even force flash the stock rom. It gets to 5% and says 'system error'
I followed your suggestion to let the battery drain and then I charged it fully, but when charging it got to 1% and rebooted the phone into eRecovery.
I wish I could get this phone fixed and back to normal.

Did you use this stock ROM for P9 (if it's EVA-L09 like mine) or something else?
http://forum.xda-developers.com/p9/development/stock-rom-dload-file-p9-eva-l09-b136-t3382818
It worked fine with force upgrade for me, while some other ROMs didn't.
Do you have Wipe cache and data/factory reset options available in eRecovery, did you try that?
I'll try that. The only problem I have is my touchscreen won't respond under eRecovery. I have to use the volume and power key to navigate. Any idea what's happened there?

It will probably return to function after you restore to stock ROM. Until then you can use power button to select items in eRecovery if needed.
Btw I have edited my original first post in this thread with step by step guide on what I did in my case.
Thank you Vernicht for all your help.
I finally manage to get the phone fully working again. I also managed to get it changed from C900 to C432, lock the bootloader and join the beta.
Thank you so much again. It's very much appreciated.
Merry Christmas too

Hi nscxp2005
how did you manage that?
i have the same Problem.
i have done a "Wipe Cache" and a factory reset.
i have copied the "update.app" from PauloBrien zip on a sd card in a folder named dload.
then i have done a Force flash -> it goes to 5% an says Invalid File.
when i look in the device with DC Phoenix it says it is a EVA-L09C900B136
Why have i done that?
My wive have the EVA-L09C432B136 and i updatet it OTA to Nougat.
i thought i could switch to that version to get the new Nougat but something went wrong......
thanks in advance and sry for my english =)

Hi Guys, hope you can help

Would like some help please.
Hello, I have the same problem, I tried to install Lineage 14.1 and it didn't work. Then i tried to go back to EMUI 5.0 and i just all fell apart. No i have no android on my P9 (cos i wiped all data and the system through TWRP 3.1.1.1), and now my touchscreen doesn't work. When i try to force install, it blockes on 5%. Anyone have any idea on how to fix it? Thanks

I have the same issue after flashing the rollback package from the official huawei site. The phone isn't rooted, it just had a branding for some odd reason. So I installed the C432B182 but somehow ended up with a C900B... firmware. So I installed the Rollback package C900B300 using the 3 button method. It said successfull but ever since I've been stuck in the same loop. At the logo. Trying to enter recovery mode (Volume Up + Power) or Force flash any of the firmwares (stock C432.. or rollback C900) doesnt succeed. It wont attempt. Only vibrates as you described and turns the screen off for a second before entering the same loop again.
How did you manage to enter the flash Menu??
Thanks in advance and hope you can help.

At me too such problem. When charging to sit at 0% and plug it into the charger, it immediately turns on and goes into the system, then the screen is worth a long logo. I have a phone EVA-L09C627B150.

i9305 bricked. Vol UP button broken: can't go to DL mode

Hello,
I tried to flash twrp on a stock i9305 through Odin.
It initially seemed unsuccessful (rebooting to stock recovery) until i rooted the phone and flashed twrp again.
From twrp i then tried to flash RR rom but it refused (don't remember detailed message). I decided to give up and reboot.
The phone stays stuck on samsung logo.
I removed the battery. Restarted with 'home+volDown+power'
All i can get is the screen telling me to press VolUP to flash a ROM. My issue is that the VolUP button does not work.
I tried to remove it and press with a pin to no avail.
I can't use adb (not recognized)
Odin sees the phone but can not flash anything as the phone is not in DL mode...
Any ideas ?
Thanks a lot!

I suggest to get a USB jig. I've always one at home. Bought mine on eBay for about 2€. Just search the web.
Thanks. Just looked it up. I'll give it a shot :good:
