Phronsis Rom Installation help required. - Galaxy Note 3 Q&A, Help & Troubleshooting

Friends, I am newbie in custom roms. Phronesis rom seems good and easy to install. Even being easy to install, I was unable to install Phronesis rom. The steps that I followed to install this rom are given below.
1) Downloaded Phronesis v6.2 rom from OP and copied it to SD Card.
2) Booted into TWRP recovery.
3) Selected "Wipe" option in the recovery menu.
4) Selected Advanced wipe.
5) From this menu I selected system, data, cache and delvit/art cache.
6) After selecting above options I swiped to wipe.
7) After this I went back to main recovery Menu.
8) From recovery menu I selected Install.
9) From here I chose Phronesis v6.2 rom from SD card storage.
10) Installation started and a bar started to load on the bottom of screen.
And after a few seconds (10 to 30 sec) my phone restated and stuck on note 3 logo.
At the end I didn't have any option but to re-flash stock firmware using odin.
It is the horror story of my note 3.
Please tell me where I have done wrong.

Read the FAQS and Q&A for the rom.
Especially the Q&A regarding TWRP
Did you go through Aroma installer ??

No sir, aroma installer did not start. My phone restarted spontaneously without going into aroma installer.

I have a similar Problem. I think this is caused by an incompatible (old) bootloader. I still use stock Android 4.4.2. When reading about how to install Phronesis I also stumble upon "update to 5.x first" to get a current bootloader.
Unluckily I'm not sure howto update the bootloader manually - but this could be the solution.

http://forum.xda-developers.com/galaxy-note-3/general/direct-download-bootloaders-modems-t3258803

Use TWRP 2.8.. latest version doesn't work. Check the MD5, is possible that the downloaded file is corrupted

You should really change the thread title to : Please spoon feed me, because i don't want to read at least the first thread page of the rom I'm trying to install !

Download the files required, ROM, RECOVERY, SUPERSU.
1) Goto recovery mode (obviously twrp recovery).
2) Clear (dalvic, system, data, cache) and not (internal).
3) Flash the ROM, then flash the RECOVERY by selecting "install image" and selecting "recovery".
4) Go back to main page of TWRP & Reboot and when it asks (system, recovery, fastboot), choose recovery.
Then you just wait, it will reboot back to the new TWRP (orange color).
5) Now flash the ROM once again. But before flashing, must clear cache again like in step 2.
6) Clear cache.
7) Reboot now. it takes approx 1mins and shows new bootanimation.
Now, when you get Marshmallow page, set everything up like in starting. Then
8) Flash SuperSU file via recovery to get root access.

[GUIDE] How to get CM 14.1 working.

Hi,
So I have created this thread just because I can see many people creating new threads as after flashing CM 14.1, their phone doesn't boot up. So for all those who are going to flash CM 14.1 or have already flashed it and can't get it working, this thread is for you.
What you will need:
1. Rooted OnePlus X (Obviously)
2. Custom Recovery (TWRP recommended)
3. Latest CM 14.1 build
4. Arsenic Kernel or BlackReactor Kernel
So this is how you get CM 14.1 working on your OPX (make sure your battery is above 80% just to be sure that nothing will go wrong considering battery's point of view)
Make sure you have backed up everything before performing the following steps as the process will wipe your data completely. (I would recommend to take a Titanium backup of all user apps and then taking a nandroid backup of system and data)
1. Download the required files and place them in your SD Card or internal storage
2. Reboot your device into recovery
3. Go to wipe, and swipe to factory reset (Note! This will completely wipe all the data from your device including app data and SMS! This won't wipe the contacts but just to be safe, have a backup of all your contacts)
4. Go to Wipe again, and go to Advanced wipe, select the following partitions - System, Cache, Dalvik cache. Swipe to wipe (Note! Make sure you have a backup of the System as this will wipe the Operating System from your phone!) Although this step isn't necessary, I like to do it.
5. Go to install, and direct to the location where you have saved the CM 14.1 zip file and the kernel. Select the files, and swipe to flash.
6. If you want anything else in your system, direct to that location, select the zip file, and swipe to flash. (Note! You need not flash the SuperSU zip file as CM offers Root access in developer options)
7. Reboot your system and wait for it to boot.
Viola! Your device is now running official CM 14.1 nightly.
Hope this helps! ?
Downloads:
1. Latest CyanogenMod nightly - found here https://download.cyanogenmod.org/?device=onyx
You can have any version of the nightly as long as it is CM 14.1
2. Arsenic Kernel R32 (or R31) - http://forum.xda-developers.com/oneplus-x/development/kernel-arsenic-kernel-r2-t3422020
Open the above thread and follow the guide

Good Evening, @aamodjoshi23 THX a Lot. You are my Hero. Finally it works.
greetings
If you're facing some Error 7 while trying to flash cm 14.1, you can try updating the bootloader following this
http://forum.xda-developers.com/showpost.php?p=69267239&postcount=2560
I used the Oxygen OS 3.13 full ROM as recommended, edited updater-script (following those instructions)
Immediately after flashing the OOS 3.13 rom, you don't have to reboot.
I immediately flashed twrp 3.0.3 original from https://dl.twrp.me/onyx/
I then rebooted into twrp 3.0.3 (using the reboot button in twrp, then bootloader)
Then I installed (in this order):
cm 14.1 (https://download.cyanogenmod.org/?device=onyx)
arsenic kernel (as recommended above)
opengapps
Not sure if this step is necessary, but I wanted to let twrp patch the rom to not overwrite twrp so I rebooted into twrp again (using reboot --> bootloader in twrp)
Then I used reboot --> system
First boot took a while, but now I have nougat!!
kenel zip every time
Do i need to flash the kenel zip every time I update the the cm 14.1 zip file?

Yes, as when you flash the CM 14.1 build, the kernel that is provided with the build is also flashed, and that is not supported. So you need to flash it every time you flash a CM 14.1 build, but if you want to flash any other build, something like CM 13.0, then you need not as the kernels provided in those are supported.

Hi,
I have a very specific problem. I rooted my Oneplus x few months back and everything was fine. I use to get update notifications and after downloading it use to update automatically. But since last 2 months i download the update files but it takes me to recovery and then i cant find the zip file to flash/install. (i also started using external sd card two months back, but not sure if it has to do anything with this). I tried searching a solution on web - tried checking 'system' under Mount tab, installed an app for auto update and some more but no use. I even connected my phone in recovery mode to laptop and copied the zip file to internal memory but while flashing it gave error.
Now i am not sure what the problem is. Do i need to update my recovery or something else. Pls help.

I made a blunder. I read somewhere to upgrade TWRP to 3.0.3 and after doing that now i just can't access the recovery mode. When i try to boot in recovery mode the screen gets stuck with One+ logo. Then I even tried to Factory reset and the phone rebooted to the same screen stuck with logo. I longed pressed the power button and it got switched off and then again turned it on. It started and is working fine but I cant factory set it, nor cant I access recovery to flash anything.

This is because you flashed wrong recovery twrp 3.0.3 is for new bootloader and you are on old bootloader..that's why it all happened..so you just need to flash old recovery..then follow given link to upgrade bootloader and recovery.

I've got a good news and bad news for you.
The bad news is, no one has the older 2.8.x TWRP image files and there are no threads that have the download links for the older version of TWRP. So you're stuck and you have lost your recovery. You have lost everything... Having no recovery means you can't do a lot of things like factory reset, any wipe of a partition, you won't be able to update your system, you won't be able to flash zip files to enhance your experience and many more... I'm sorry my friend...
The good news is, I've got you covered. I had saved the older TWRP so that if anyone one day would need that recovery image, I would be able to help them.
Download the older TWRP from here : https://drive.google.com/file/d/0B2Ms-zaNd3SiTmpxX0UtYUV2R1k/view?usp=drivesdk
Flash it. You should get back your recovery.

By stuck on boot, I didn't know you meant that it showed only the OnePlus logo and not even powered by Android.
In that case, follow this guide to update your bootloader :

Recovery crash when flashing custom ROM

Hi everyone,
I posted this thread in general troubleshooting category and after some advice, I decided to post it in the S4 section.
I was since 3 years on custom ROM (CM and Lineage OS) and due to substratum, I had a bootloop.
My problem is quite particular, after a total clean (wipe and format cache,system,data, dalvik cache) of my device and flashing the stock ROM, custom recovery cause me some trouble.
Whatever I try (CWM touch 6 or TWPR 3.1.1), I can't flash custom ROM (Lineage OS 14.1), TWPR or CWM crash 1 second after the flash command and reboot, with disable touchscreen and even by using old navigation way and try again, same problem.
Tried also to disable file signature check but no effect.
Quick summary about what I did:
- Device: Samsung Galaxy S4 (GT-I9505)
- ROM stock used: I9505XXUHOJ2 ( the build on which is based the CF-Root file I used) and Bulgarian version due to mistake.
- I tried on these two ROM with in the two cases, no patch or Samsung ROM update made.
- Tried to install CWM by ROM Manager and ODIN (v3.09)
- TWPR installed by TWPR App using file in .img and not the second option (tar.img) for LTE Internationnal Qualcomm.
-Checked the root before last attempt with root checker and it was ok.
- Made 4 times already the clean and Stock ROM flash to clean recovery and try another way to install it (never had error after recovery install).
Actually I'm on the OJ2 Rom with update and patch delivered by Samsung with classic method.
In advance thanks for your help and I really hope it's not too serious.
By the way, sorry for my english, it's not my native language
Try flashing the stock ROM from sammobile.com or updato.com, don't root, use Odin 3.07 to flash the tar version of TWRP 2.8.7, try flashing a custom ROM.
Thx for the help/advice
Just to be sure, my stock ROM is actually from up updato.com but due to the patch and Samsung update I'm now on HPK2.
Here the detail of my stock ROM
https://image.noelshack.com/fichiers/2018/05/4/1517503670-screenshot-2018-02-01-17-43-00.png
(the integrated image link option made it as large as the moon so I prefer a simple link)
TWPR 2.8.7 is still efficient or another version would be better ?
If yes, I will try in the hour and I will give you news as soon as possible
EDIT: After some research, TWPR 2.8.7 jfltexx is not avaible in .tar , only .img and impossible to find it on net...
But 2.8.6 and 2.8.4 are avaible in .tar and 3.0.0 in .img.tar , which one is the best ?
I suggested 2.8.7 because Ihave used it in the past and it was very stable. Try a newer tar version. It's really just to see if the phone will take TWRP and boot it.
Whatever I try (TWRP 3.0.0 and 3.0.1 in .img.tar for jlftexx)
Odin (v3.07) do the job , my phone reboot as normal.
But when I shutdown it and lauch in recovery by manual way, got during a micro seconds the android logo of loading and intant "No commands " and I end on the stock recovery.
Edit: I will try the same method with Odin using CWM tar (never had problem with it before this day)
Same thing with CWM-v6.0.4.7-Touch-GT-I9505.tar
Android loading logo and "No command detected"
Problem solved
Well, I don't know how I made a sucess but it seems the "wild" method worked.
So here is the list of things I did in case somepne got the same trouble
Put your Zip file on SD AND Internal Memory (in case)
All the Zip files I used where on my internal storage during this procedure.
- Download mode:
uncheck Auto Reboot in Odin
flash TWRP3.0.1.0 jlftexx.img.tar with ODIN in admin mode
turn off device after flash ended
Obligation or the stock recovery will return automatically !
Lauch device in recovery mode:
If it's TWRP good news, slide to confirm modifications.
Recovery mode:
-Wipe --> Advanced Wipe--> Select Cache, Dalvik Cache, Sytem and Data (never check internal and SD storage)
I tried by mistake without wiping dalvik cache, and got no boot after 5 minutes so i made it again with all the wipe above
-Install --> Flash zip of the rom and Gapps (got an error at zip signature check on the ROM so I flashed after uncheck this option)
-Reboot --> System
Let your device launch on the new rom, set the basic parameters and after, if you want, return in recovery to flash the SU addon for root (got also zip sugnature fail so I ahd to uncheck it again)
Hoping no one will ever had the same problem but in case, I share my solution
Thanks again for help

Questions about upgrading Lineage OS 16 to 17

Hello,
I do have some questions about upgrading LOS from 16 to 17, maybe someone can help me bringing a little light into this upgrading process.
- Is the sideload way the correct way to do this? ( https:// wiki.lineageos.org /devices /fajita /upgrade)
- What´s about the play services, I dont have any installed ( ..."If you did not have Google Apps installed, you must wipe the Data partition (or perform a factory reset) to install them"...) So if later on I want to install e.g. opengapps I have to wipe all my data after upgrading to 17??? (How? TWRP - wipe -advanced wipe - data and cache ???)
and what´s with all may data? I have titanium backup pro (no SD card), so I backup may phone, put it to my PC, upgrade to 17, wipe all data, put the backup back to phone and reboot?
Or do I have to install Magisk.zip and titanium.zip from within TWRP again first
- What do I do if the sideload fails?
- Can I do the upgrad process with TWRP too? (copying and installing from within TWRP?)
- And what about with the A/B slots, no installing twice on both slots?
As you see, I am unsure on how to do things right and I only did this once before as I installed Lineage OS.
(This would be the way I would do this:
- backup all data to PC
- Boot into TWRP
- copy LOS17.zip. Magisk.zip and Titaniumbackup-pro.zip into internal storage
- install LOS17 and boot into TWRP
- wipe data and cache
- install magisk and TB
- copy all data back and restore? (only user data or the system data too??))
Maybe someone can help me with this. Thanks!
My guide for installing Lineage maybe helpful: Guide Installing Lineage
I would recommend a clean install. Most that have tried to follow that wiki have had issues (if you look in the LOS thread). I haven't used. TB zip, but I did use my TB data from the app without issues. If you dont use Gapps, just dont install them. Skip that step. You still have to reboot to recovery to install Magisk though. I dont think I would try a TB zip until after the first boot.
Installing twice is for the intial install to get the same thing on both slots. You dont want Android 9 on one slot and Android 10 on another, or LOS 17 on one and OOS on another. Once you have LOS 17 on both slots and go to update you will just flash once. See my guide about doing an update.
Thank you for your reply,
so if I got your answer right, I should install the LOS17 like the LOS16 before, as a clean,fresh install.
Seems reasonable to me
I will do the same steps as you gave me before https://forum.xda-developers.com/oneplus-6t/help/instructions-installing-lineage-t3949628
- Backup everything to the PC, so you will need to copy all your data over.
- Sync all your accounts, etc.
- In TWRP format data. Reboot recovery
- Factory Reset.
- Flash Lineage
- Flash TWRP Installer
- Reboot to Recovery
- Flash Lineage (This is only the first time, to get the *** rom on both slots, only do this for the first install)
- Flash TWRP Installer (This is only the first time, to get the *** rom on both slots, only do this for the first install)
- Reboot to Recovery (This is only the first time, to get the *** rom on both slots, only do this for the first install)
- Flash Gapps
- Flash Magisk
- Reboot to System.
- Then you should be able to setup the device, copy everything back over. Restore your data.
Will do the flash on weekend, then I will let you know....
Thanks.

To put it short: a disaster
What I did:
- Flash Lineage
- Flash TWRP Installer
- Reboot to Recovery
- Flash Lineage
- Flash TWRP Installer
- Reboot to Recovery
- Flash Magisk
- Flash TB
- Reboot to System.
What I got was a "Qualcom Crashdump Mode" kind of report
What I used: lineage-17.1-20200418-nightly-fajita-signed / twrp-installer-3.3.1-1-fajita / Magisk-v20.4
So I thought maybe the "no factory reset" at the beginning may caused this problem, so I started the whole flashing again.
Long story short: Being distracted I once forgt to flash TWRP after the LOS and now I am stuck in fastboot.
Cant get anymore into TWRP, "fastboot boot TWRP.img" always throws me into fastboot forever wait
Tried to flash TWRP direct from fastboot "fastboot flash recovery twrp.img", always get a write error.
So, at the moment all I can get in is the bootloader, and I have no clou how to get TWRP up and running again.
Edit: Managed to get into TWRP again, but this double flash + Magisk always gives me this "Qualcomm Crashdump Mode"
Help would very much appreciated!

So you tried to go straight to LOS 17, used an old version of TWRP, and never wiped data while going between Android 9 and 10? None of that will work. I think didn't make it clear, you need you need to be on the OOS 10 firmware first. Flash OOS 10 to both slots, at this point using the fastboot ROM would be my suggestion, like my [Guide]Installing Lineage.
Once you have Android 10 in place one both slots, then start your OS 17 install. Note there is a cliff notes version of that guide in the second post, if you don't want all the "wordy" details.
Oh my, I really didn´t understood the step with "get OOS10 on both slots first"
I am often a little sloppy with details, bad habit, will take some time tomorrow and do the reading and the flashing then.
Thanks again.

Make sure you use the"unofficial" version of TWRP, linked to in that guide, rather than the outdated official one you used before as well.

So, LOS17 is up and running, I did it the long way but good to know the fastboot Rom method now. I confess some part of this thread would not have been necessary if had read your installations instruction carefully....
So let me thank you for patience und help, "Reading broadens the mind", I often tell others, will remind myself nexttime

Custom rom - I've messed up

Hi all,
So many years ago I used to do this flashing the custom roms on my old galaxy s4, and it was pretty straight forward.
THis s8 though is giving me real problems.
I'm trying to flash lineage 19 on it but I just can't seem to do it. I have run into error messages, boot loops, apparently deleted the boot sector off after using TWRP which only worked once...
I have googled and googled but I can't find the exact guide for my phone. It's a UK phone.
I have managed to get a samsung rom back on it using Odin, but it's got so T roam option which doesn't do anything..
Please can someone help?
It should work like this:
1. Enable OEM-unlocking in the developer options
2. Download the no-verity-opt-encrypt rom (google it, you will find links) on an SD Card or if you can plug that in your phone on an USB Stick
3. Install twrp using odin ( you was able to do this, right?)
4. Boot into twrp (Do not boot in the os first, go to twrp directly after flashing it)
