[SOLVED] Bootloop after RocketRom-boot into recovery? No CWM options, only ODIN Mode

Hi Folks
I am trying to solve the problem of my Note going into a bootloop after a Rocket Rom install. Not sure what caused it, perhaps i didnt freeze the WiFi well enough?
So here is the scenario:
Rooted and working Galaxy note with CWM installed. Current rom was backed up. Zip of Rocket Rom was placed in the sdcard folder on the phone and the phone was then rebooted into CWM Recovery mode. The "install zip from SD card" is selected and the process ran and completed with no errors.
Now, as the Note restarts, it goes into the bootloop at the Rocket Rom loading screen.
I searched for possible answers on this forum as well as other Android forums but could not find a relevant solution for the note. Other phones solutions did not work...
So now i am trying to restore the phone back to stock from backup or another rom by holding Vol+Power+Home buttons. However, this does not get me to the regular CWM scroll screen with options! It takes me to ODIN Mode big green android logo with "Downloading... Do not turn off target" under it instead... So i cant re-flash it via CWM?
Using ODIN on my PC - dont know what files to select for BOOTLOADER, PDA, PHONE, CSC... Not sure if this is the best solution either.
How can i recover my device? Thank you in advance!

I was in the same condition because installed 19_1 without 19. I flashed an older rootable stock rom with odin via PC, rooted it and installed CWM, then installed 19 and 19_1 afterwards.
Select PDA and then the .tar file. It would do. Here is a tutorial, it is the same for SGN:
http://www.youtube.com/watch?v=cEjTaFg_2Ks

Thank you i am going to try that! I actually went with v19, didnt do 19.1

Keep in mind CWM recovery is VOL UP,MENU,POWER NOT VOL DOWN.
Got me out of the same situation last night where it would only go into ODIN mode and nearly gave me a heart attack

Thank you!! I actually just figured that out a few minutes ago myself, after pressing the buttons and rebooting a bunch of times all of a sudden i booted into the CWM menu... Must have pressed the Volume UP by accident I tagged this post - might be a good tip for someone running into the same issue and doing a search on here. Such as simple solution, but if you dont know it - can be very frustrating
So the issue is solved - was able to wipe all and re-flash with Rocket v19. Now on to sync all accounts and restore all apps with Titanium back up Pro. Thanks again folks good of you to jump in and help me out.

just on that...do you reboot the phone inbetween the 19 and 19.1 or do you just choose to install 19.1 zip straight after installing 19 without rebooting the phone

I having same problem, but I still cannot go into download mode or recovery mode (CWM)..
I was using CWM to flash RocketRom V19
Any ideas guys?
Help needed
When bootloop If I press press power button long the phone turn off a while then reboot automatically.
I even tried remove the battery then try to go to CWM menu (vol up + home) then power..
Or vol down + home (download mode)..
But failed..
I'm getting scared now

From viny2cool:
1. remove the usb cable, battery, sdcard, SIM.
2. wait 10 seconds, then insert the USB cable.
3. press and hold the 3 button combo while you insert the battery
4. continue to hold until phone's screen goes black twice and release power button.
5. timing is critical, it may not work the first time. Keep going until you see the COM port is connected properly.
I flash using Odin and my Note back to Life x_x

Rocket v21
Flashed couple of times exactly the way Rocket install procedure, Note goes into bootloop. Finally have to do Stock flash.Its the worst ROM I have come across for all those Android phones I used with.

[GT-P31xx] CF-Auto-Root

Check your device model ! Settings -> About device -> Model number. See the third post for exact supported model numbers. If your device is a totally different model, it will not work (may even brick) !
CF-Root is the root for "rooting beginners" and those who want to keep as close to stock as possible. CF-Root is meant to be used in combination with stock Samsung firmwares, and be the quickest and easiest way for your first root.
Donate
CF-Root has been available for many devices and has clocked over 8 million downloads. This is not even counting custom ROMs that already include it. Don't be a leech, buy me a beer (and use the "Thanks" button!). Imagine if every CF-Root user has donated me $1...
What's installed
- SuperSU binary and APK
- Stock recovery
Installation and usage
Flash the CF-Auto-Root package as PDA in ODIN (details on how to do that are in next post), and your device should reboot into a modified recovery (signified by a large red Android logo) and it will install SuperSU for you and restore the stock recovery, and reboot back into Android.
If you don't get to the red Android logo, boot into recovery manually ("adb reboot recovery", or boot while holding Power+VolUp+Home).
Using this root increases your flash counter. You should run Triangle Away (see below) after rooting to reset the counter. Note that if you want to run custom kernels or custom recoveries, your flash counter will be set to 1 at every boot. Either configure Triangle Away to reset the counter at every boot (Play version only) or only reset the counter when you need to go into warranty.
Did you see the red Android logo during rooting, but SuperSU does not appear? This may sometimes occur due to left-over files and settings, however, you can usually install SuperSU from Google Play at this stage and it'll just work.
Not included - Triangle Away
Triangle Away can be used to reset the flash counter after installing CF-Root. The flash counter keeps track of how many custom firmwares you have flashed, as this voids warranty. (No idea what this about ? Read up on it, you will want to use this !)
Not included - adbd Insecure
As this CF-Root does not include a custom kernel, adb shell does not have root access by default (you can still get it by typing su inside the shell), nor is adb remount supported, nor will adb push and adb pull work on system files. adbd Insecure can be used to remedy this situation. (No idea what this is about ? Don't worry about it !)
CF-Auto-Root homepage
http://autoroot.chainfire.eu/
CF-Auto-Root main thread
[CENTRAL] CF-Auto-Root
For requests for new roots and generic discussion - please keep device specific discussion in the thread you are viewing now.

ODIN Installation (detailed)
- Follow these instructions to the letter. Do not touch any buttons or checkboxes that are not listed below to touch!
- Unzip the attached Odin3-vX.X.zip file
- Download and unzip the CF-Auto-Root-....zip file (see posts below this one)
- If you end up with a recovery.img and cache.img file, you've extracted twice. You need to end up with a .tar.md5 file - don't extract that one
- (USB) Disconnect your phone from your computer
- Start Odin3-vX.X.exe
- Click the PDA button, and select CF-Auto-Root-....tar.md5
- Put your phone in download mode (turn off phone, then hold VolDown+Power to boot - if it asks you to press a button to continue, press the listed button, or run adb reboot download command)
- (USB) Connect the phone to your computer
- Make sure Repartition is NOT checked
- Click the Start button
- Wait for Android to boot
- Done (if it took you more than 30 seconds, you need practise!)
- NOTE: Sometimes the device does *not* boot into recovery mode and root your device. Just do the entire procedure again if this happens. If it still will not install root and such, make sure that in Odin "Auto Reboot" is not checked. Then after flashing, hold VolUp+Power (for several seconds) to boot into recovery manually. This will start the install process.
New to Samsung? Unfamiliar with Odin? Think all the above is a hassle? Get used to it. It's very simple, and us Samsung folk use Odin (or Mobile ODIN ) for everything! It's so very very convenient once you get used to it. Notice the 30 second comment above? For experienced users, the entire process indeed takes only 30 seconds!
You may now optionally want to install and run Triangle Away to reset the flash counter.

Do you have a blue progress bar on screen below the Android ?
If it's full, just reboot the phone.

45 min, may have a problem? HELP!

Just reboot your phone. Pull the battery, hold power button, whichever works. Then see what happens.
DONT PANIC. Nothing bad has happened.

Not the tab, but ODIN had a bunch in the lower left. succeed 0/failure 0 and the last was please wait.
I think it's a driver problem as I did root something else a few weeks ago? But there was a SAMSUNG driver in device manager with no exclamations.

Was a driver problem in win7 64b. Rooted now and Ti backup works great. Thanks a bunch.

corrupted recovery

First thank you for all the wonderful work there to help us make the best out of this phone.
Yesterday, I tried to install the CM10 ROM (cm-10-20121126-UNOFFICIAL-ancora_tmo) but encountered a serious problem. Since I flashed a custom ROM last time in Aug., I haven't updated the recovery (CWM-base Recovery v5.5.0.4b). When I booted into the recovery, I found it lost all its functionality. To be specific, any selection on menu options (reboot system now, ROMwipe, wipe cache, etc.) yielded no result but a screen with a circling arrow covered by a hat. After that only the power button worked and it would simply bring you back to the main menu. I tried to communicate with the phone in ADB mode and it worked (by that I mean I can reboot it from windows command shell: adb reboot recovery). Now I have no way to update the recovery and install new ROM from there.
Any help would be highly appreciated.

If you can communicate via windows then install Odin and flash from it. Full instructions is on the wiki page

This may seem stupid but how are you selecting something? You should use home capacitive not the power to select. This symptom is the result of tapping the power button, its kinda like sleep

I'd followed the instruction and found the Odin rebooted to the exact recovery! There it showed a few lines like:
Galaxy Exhibit CWM-based Recovery v5.5.0.4b
Finding update package ...
Opening update package ...
Verifying update package ...
E: failed to verify whole-file signature
E: signature verification failed
Installation aborted.
Now the phone can not boot into the original ROM.

When booted into recovery use volume keys to navigate in cwm. Also retry to download the ROM and try cwm before Odin.
Odin is on computer and phone is hooked via USB cable. It cannot boot into cwm if followed Odin. You ha e to download Odin and drivers for cell to be recognized.
Do a YouTube search for Odin and watch the vid it will show you. Be it noted that cell will need to be set into download mode and USB enabled.

Yes, I used the home capacitive to select those options on the main menu. No matter what I choose, however, the power button can get me the circling arrow with a hat. Another push on the button, you are back on the main menu.

You are deffeinitly booted into cwm so I suspect from the install error that the signature verification is what's failing. Try another ROM or redownload and try again

I've redownloaded the uvlg3.odin.zip package and checked its MD5. Everything is OK. Then followed the instruction on the Wiki page, but ended on the same CWM recovery screen with the same error message.
The problem is: it seems like the phone boots successfully into the recovery, but it only shows the main menu with no option functioning (like I described before).
Has anyone read about similar problem anywhere before?

Are you running Odin with your phone in Download mode? Like they said, Odin shouldn't re/boot into recovery automatically.
Also make sure the auto reboot option in odin is cleared.

Many Problems with installing Cyanogenmod on LG Optimus 4X HD...

Hello everybody,
so I'm as new to this forum as I am to the android world. Just this Wednesday i bought a new LG Optimus 4X HD on amazon.de
Thought it would be nice to start of with Cyanogenmod.
So I started my search for some good "How-To's"...it were many I went through and I already invested many hours in getting this running. Sadly it still doesn't work. I actually wanted to stay with one How-To but at one point there's always a download not working so that other sources are needed.
So what did I do...
-I rooted it yes (at this point I needed to download "Rooting Toolkit for Optimus 4X HD" which wasn't downloadable so i switched to another How-To, btw. first How-To: http://androidlegend.com/android-4-2-1-via-cyanogenmod-10-1-for-lg-optimus-4x-hd-p880-cm10-1/
-Installed "LG 4X Recovery 1.2" and installed this way CWM.
-At another point here I installed ROM Manager, installed it and went into Recovery and here happend the first problem, kernel panic.
Said something like "couldn't load kernel/wrong kernel", kernel panics...Me panics too
Anyway, force kill -> auto reboot -> still kernel panic -> again -> batterie out and a few times with usb cable connected to PC -> Batterie again, works :good:
Ok so Clockworkmods Rom Manager seemed to be not that good... did recovery boot with LG 4X Recovery, tada works, I go into the folder with the Cyanogenmod-zip and want to start the ROM installation and it says Status 7 (of course I googled Status 7 and searched here in the xda-boards for it, nothing helpful found yet)
Installed older version of LG 4X Recovery (1.1), still same fault.
I uninstall the ROM manager, redownload and reinstall, try to backup -> Kernel panic.
I search for a different How-To, yet nothing good happened. Others go something similar and say "at booting press On-Button and Volume down-button at the same time", I do that -> Kernel panic
I have no idea whats wrong with the kernel...but normal booting works fine.
Next I read something about needing to unlock bootloader, have a workthrough aka this http://forum.xda-developers.com/showthread.php?t=2224020
After I enter "adb reboot oem-unlock" in DOS command window it should say something concerning "open bootloader", but not in my case, just a normal reboot happened (this is what it looks like at least). Checking the hidden menu also doesn't show anything as I don't have the option with the boot-loader status there.
Next trick, I go to LG Recovery again and first wipe the whole stuff and try then the Cyanogen istall, still doesn't work and as I wasn't able to backups before (tried Titanium but it froze at 12% and the stuff about ROM Manager is told^^) I now had a clean factory install, all my work before lost, nothing rooted and still a kernel which panics when I do the "safe-boot"(this volume- and on-button-thing).
I also tried 3-All-in-one solutions, neither of them worked. (2 german ones, and one english one)
So I think thats it, ah wrong, still not finished. I also tried to install a new kernel to erase that f****ng problem with the kernel panic. I choose to use WerwewolfJB_v005 http://forum.xda-developers.com/showthread.php?t=2256899
the easy and fast way made the same as the try before with the "open bootloader"-try, just normal restart. When I enter the second line in the command line, it just says "waiting for device".
So yeah, thats it. I don't know what else to do. Does anyone know what I could also do, or is this case unsolvable? Is the Smartphone broken or did I make a mistake at any point? What should I do?
I'd be super glad if anyone could help me here. I hope I described my case well enough. I hope I didn't forget anything.
Thanks in advance!

I am also new to this stuff but maybe i could help you anyway
What is the Firmware Version of your phone?
(Sorry for bad english )

The old "adb reboot oem-unlock" didn't work for me on UK, v234-000 either. I followed this thread instead and it worked perfectly first time.
As long as your phone has been turned on and connected to the network for long enough on v20x you should be fine - once you get the notification from LG about your phone being registered or similar then you'll be fine, normally a couple of hours.
Just reflash your phone to stock, wait for the notification and try the two-step method from the above post and you should be fine.

root , recorery and unlock boot loader
you must have your bootloader unlocked in order to flash kernels
( this worked for me but I can't guarantee it will work for others you can only try !! be aware when messing with firmware and bootloader you warranty could be voided )
make sure your phone is rooted you know if it is rooted because you will have superuser installed in your apps ( grey square icon with green android head on it ). if not I used this method to root my phone so try this http://forum.xda-developers.com/showthread.php?t=2180688
if your phone is rooted next you will need a recovery this will help to backup your phone and create a restore point so in case any thing goes wrong. to install a recovery go to play store and download rom manager ( clockworkmod ) once installed open rom manger and select recovery setup. then select install or update recovery then select your phone ( lg optimus 4x hd). then select flash clockworkmod recovery. and then wait while it downloads and setup . hopefully when finished it will say succesfull. ( make sure phone is rooted or it wont work ) to check clockwork mod is working you can reboot into recovery through rom manager or power off phone then hold volume down key press power button to power up but keep holding volume down key until recovery boot up. ( be a wise option to backup phone now in recovery)
next to unlock bootloader ( so you can flash roms with kernels) go to this thread, http://forum.xda-developers.com/showthread.php?t=2224020
and download the BL_unlock_new .rar file when its download copy it to your desktop on pc and then extract it to desktop on pc . now make sure your phone is not connected to your computer go to phone settings,then go to development options, and then select usb debugging on. once debugging is on now connect your phone to pc wait for it to connect you can keep your phone on charging mode. now open the BL_unlocking_new extracted folder on desktop on pc and double click on the BL_unlock file a box should open up on your desktop asking you to tap a key to continue so press a key now your phone should reboot and some white writing will appear on screen .on your desktop the bottom line should say please... now tap a key on computer it should say press any key to continue < waiting for device> now disconnect phone from computer look on phone screen it should say now ready! now hold power button for 10 secs and let phone reboot. to test if bootloader is unlocked on phone go to dail pad and dail this 3845#*880# you should get the hidden menu on your screen scroll down to bootloader unlock check and select then select bootloader unlock check and hopefully it should say unlock...
now you have root , recovery and bootloader unlock, now you can download a rom for this phone copy rom ( should be a zip file ) to your phone then open rom manager on phone and reboot in to recovery or power off phone, hold volume down button then press power button should now boot into recovery then you want to use volume keys to scroll down and select wipe data/factory reset with power button then scroll down and select advanced then scroll down and select wipe dalvik cache then you want to select go back then select install zip from sd card then select where you saved your rom sd card or external sd card then select rom then select install...
hopefully if that's helped you or anybody else ...

If the OP can possibly get his bootloader unlocked following the official method then he should, rather than using that file. Nobody really knows what all the 'fuses' that are blown by using that file do and that would certainly result in his warranty being voided in any country, whereas in a lot of countries his warranty won't actually be voided by using the official unlock method.

Ok, thanks for the answers so far. But still, wasn't able to get any further.
@Dexxon: Firmware version is 4.0.3
Besides: Kernel Version is 2.6.39.4 and there's also something written like "[email protected] #1" in the hidden menu...is this normal? AP Bootloader Verison unknown and AP OS Version is 2.6.39.4 also this jinwoo...
@SimonTS: I tried to unlock the bootloader with your link and advices (which is the same as i tried before).
Got a message saying "Thanks for buying this LG Phone..blabla" and I guess thats what you mentantioned about that informing.
Battery was loaded to 100% so i connected it to PC, said "LG Software Mode Connection" on the phone (before I always took that "data exchange connection"), went to the adb folder and made a command window there, entered "adb reboot-bootloader", smartphone reboots, should stay in LG window screen, but it doesn't. It just boots totally normal into the home screen.
@Hursty uk: As I said in the first post. Everything regarding the ROM Manager from CWM sends my Phone into kernel panic. As this is quite hard to get a normal reboot again (even battery out for some time and back-in doesn't solve this) I really prefere to not use this option. As it is just frustrating and doesn't help.
And yes it is already rooted (I have SuperSU and I checked it with the "Root Checker"-App) Everything says it is rooted. I rooted it with that method: androidlegend.com/how-to-root-lg-optimus-4x-hd-o4x-p880
Ah I really don't know what else to do. Is something just wrong with my device?
btw I also can't do a software update with the LG Software from there website, so I could at least go 4.1 instead of 4.0.3 atm...
When I try it that way, and install the USB-Drvier for LG P880 the SW-Update button stays grey and is unclickable even though the phone is connected.

To unlock the bootloader following either of the official methods requires you to be running v20x (The LG Stock v4.1 code) first, so that is why the commands are doing nothing for you.
For the moment, forget about CWM, Root, Bootloaders etc - the key thing is to get your phone working again. Can you reinstall stock v10x software following the guide on this page?

To unlock the bootloader following either of the official methods requires you to be running v20x (The LG Stock v4.1 code) first, so that is why the commands are doing nothing for you.
For the moment, forget about CWM, Root, Bootloaders etc - the key thing is to get your phone working again. Can you reinstall stock v10x software following the guide on this page?

that would of been my next answer @SimonTS . A while back a flashed something on my phone and it got stuck at the lg bootup picture what I had to do was re-install original firmware ( through KDZ files) to get my phone working. I would try the link @SimonTS suggested .

He might as well just flash JB with flashtool, saves him flashing ICS just to flash JB straight after

Indeed - sorry, having a slightly dense day and was more thinking about getting him back to the stage at which his phone was working correctly before.

Thanks for that link, I tried it but that also didn't work (at least I guess so...)
I did everything like said at the link but at the last point the program (kdz_fw_upd.exe) crashes. Tried it 3 times, every time as administrator like mentioned in that forum post. I'm using Win 8 64bit btw...
Screenshot is in the attached .jpg. My system is japanese, but I think you can figure out what this kind of window means. It just says that the program isn't responding and needs to be shutdown.
I tried it like mentioned with putting the battery back in when the log starts and without putting it back in, in both cases the program crashes after a few seconds (~10 secs) when started.
Where do I actually see which V**x version is installed? If v10x or v20a? Surprisingly the LG Support Tool said I have v10H when the phone was still connected after the crash. And it offered me a SW-Update. But I haven't done that one yet, not sure if that would work correct...

@ chrisus
man, what is your phone status now?
in what situation you are actually?

+1 this. Also, there have been many problems with running these apps using Windows 8, and you need to make sure you're not using a USB 3 port as they being other problems in to the equation.

Ok so I've flashed JB with the LG Updater (without batterie and volume down button pressed connecting to PC, than start the update -> meanwhile putting batterie back in)
JB worked just fine and I also don't had the problem with the kernel panic when booting with volume down and power button.
So I thought, everything fresh and also different, I might give the ROM Manager App again a try (after I rooted it that way: http://forum.xda-developers.com/showthread.php?t=2180688 )...well, wasn't that smart. After I installed the Recovery for P880 in the ROM Manager, i made a normal boot (just for sure), back in the app, i wanted to go into Recovery mode and again kernel panic, bit different this time cause it does a shutdown after 5 seconds^^
Anyway, this way it didn't work, from now on I also couldn't go into safe mode anymore, same kernel panic.
As this kind of recovery doesn't seem to work, I tried the "old" way with the "LG 4X Recovery" I mentioned before. After recovery installation i just wanted to boot normal aaaand nothing happened. It stayed in the LG screen. Restart and anything didn't help here so I backed back to v10H with previous methods. Now I just got a security error saying "morning call is empty", no idea what that means but I just did the same method for JB again.
Worked afterwards, so I wanted to try it without ROM Manager Recovery installed and just LG 4X Recovery, (after rooted again of course) and it didn't boot again. Same game again.
So now I have JB installed, I'm going to root it now again, but I don't know what way I should go for doing the Recovery Part. I'm stuck on point 3 here
Any advices? btw thanks a lot until here, at least I made it half-way-through to JB now. Worst case I'd stay with that one at least.

I'm not entirely sure which threads you've been reading. Once you have the stock v20x ROM on your phone, just leave it alone for a few hours and make sure it is fully charged
After that, try to unlock the bootloader before doing anything else. If that works then you can worry about CWM and custom ROMs.

ok.
now i suppose you have a functional rooted JB 4.1.2 device.
from that you have to going on to rest of the steps to have CM installed on your device.so if it is not that (functional rooted JB device) is need to flash again JB and rooted again.
if you have the proper kdz file the tutorial for flasing is there: http://forum.xda-developers.com/showthread.php?t=2069723
and the tutorial for rooting device is there: http://forum.xda-developers.com/showthread.php?t=2180688&highlight=root+jb+4+1+2+
after that make some reboot of device to verify that:
1. the device boot to system normaly a few times (just let the device boot itself)
2. the device enter in S/W Upgrade Mode (with the device off, put the USB cable in device and PC or in device and AC adapter and press VOL DOWN + POWER) a few times
3. the device boot in Stock Recovery (with the device off, press VOL DOWN + POWER) a few time.
if you can manage to do this tree steps a few times normaly then you have a fully functional device and we go to next step that is Custom Recovery
the chance to make this steps without errors is more big if you start from scratch meaning fully wipe the device and flashing stock LG software on the device.
so, let as know here when you are ready...

he should unlock bootloader before flashing custom recovery.
so, dont use rom manager before you unlock bootloader, that's why you get kernel panics.

GT-I9295 Brick? Stock ROM fail on system.img.ext4 in Odin

Hi all.
A newbie, I ended up lost after trying to flash the latest CM 12.1 on my Samsung Galaxy S4 Active GT-I9295.
At first, there was an issue with the recovery, which upon entering showed black screen instead of the tool itself.
Trying to fix this, I managed to remove the recovery through flashing the Stock ROM, which has failed in Odin on the "system.img.ext4" instead - could not paste screenshot link here, feel free to ask for it, please!
I must say that I have tried hard to figure out what to do with the mess I have caused, but now I am helpless.
Would anyone give me some nice piece of advice to get my phone going again?
Thank you so much!

Did you try odin 3.10 by any chance? That could be the problem. Use odin 3.07 or 3.09, boot manually into download mode with complete shutdown & using vol down + power key and odin the stock ROM, reboot and do the same with TWRP (hold down the vol up key after flashing recovery when it is rebooting)

Hi there, Jason.
Yes, I did exactly as you say - got to the download mode, plugged in, ran Odin (tried 3.10, 3.09 and 3 v1.85) started flashing the latest Stock ROM and the I only got as far as the "system.img.ext4", when the download failed. Sometimes that happened even earlier, saying that there was no PIT etc.
When trying to flash the CWM recovery, it goes through OK, but then when trying to get into it, the screen just goes black, as described in my previous thread - "CWM or TWRP Recovery Black Screen".
I am stuck.
But I still hope that I am not a proud brick owner

Are you using the original USB cable if not then try with another cable. Also what is the device name shown when you boot into download mode

Hi. Try this:
Remove the battery and USB cable from your phone, and wait at least 3 seconds.
Place the battery only back in your phone.
Fingers on volume down and home, then another on power. (cold boot directly into download mode - this is important!)
Press up to enter download mode.
Insert USB cable into phone and lie it down somewhere it won't move or be touched during the flash.
Download a good current copy of Odin from:
https://idlekernel.com/flash-tools/Odin_3.10.7.zip
Extract the archive and run Odin.exe
Download this emergency recover tar for your device (newest firmware revision available as of right now):
https://idlekernel.com/flash-tools/recover/BL_I9295XXUDPA4_RECOVER.tar.md5 (also has official TWRP 3.0.0-2)
Insert "BL_I9295XXUDPA4_RECOVER.tar.md5" in the [BL] slot.
In the Options tab put an [✔] in the "Phone Bootloader Update" checkbox.
If you don't have anything you need on your internal storage, put an [✔] in the "Nand Erase All" checkbox.
Click [Start].
Once the progress bar is near finished, place your fingers on volume up and home to enter directly into official TWRP 3.0.0-2.
If you used the "Nand Erase All" feature earlier, you will need to go into Wipe -> [Format Data] -> type "yes" for your data partition to be usable again.
Hopefully this will get you past your black screen issues.
PS. Remember to flash stock boot.img with your system.img.ext4, as you cannot boot a ROM without a matching boot image.
