[Q] ANNOYING S4!! Help needed

Ok guys, here's the deal. i bought a secondhand s4 which was advertised as a google edition. it has a couple of annoying issues, first i noticed it switching itself off and on. the worst problem with it is that when my battery goes reeeally dead it just bootloops when i have recharged. the only way i can get it back on is to start it in recovery mode (which is clockworkmod v6.0.4.4) then do a factory wipe. so yeah thats a major pain. the s4 itself is a red model and behind the battery it says its a gt-19505, however in the settings on the phone it says its a gt-19505g.
my goal is to install an official firmware if possible that i may be able to update easily, the worry that i have is that i dont know if it would then accept my network as although it appears to run google edition custom firmware it may not once i install something official on it. this may be a nooby statement i know but a noob i am lol.
if its at all possible could i keep the cwm recovery?
and if its any help when i load the other boot loader thingy (with the green android on it) in the top left it says gt-19505, im just sayin cus im sure its vital which ever this phone actually is.
here are as many details as i can give but please ask if im missing anything
ANDROID VERSION 4.4.2
KERNEL VERSION 3.4.0-faux123-KK44-GE-Custom
[email protected]omain #20
Sun Dec 1 02:30:28 CST 2013
BASEBAND VERSION 19505XXUFNA1
BUILD NUMBER KOT49H.S001.131204
also upon booting in the top left it says "kernel is not seandroid enforcing
set warranty bit:kernel"
THANKS FOR YOUR TIME And please tell me where to start as i tried updating it via kies to fix it but it just wont connect, i assume due to custom firmware.

The Google Play Edition S4 devices didn't come in any color but white. Therefore, this is an I9505 with a custom ROM on it. The download mode screen reading GT-I9505 confirmed it.
Since this is an I9505 and not an I9505G, the main question is whether this device will work with your SIM card. For that, simply insert your SIM card and boot the device. If you get signal, you're good. Otherwise you'll have to unlock the device, either by purchasing an unlock code from one of the sites that sells them, or by trying the unlock methods available on the forums.
This will also help answer the question of which stock ROM you can install on the device. If the S4 doesn't prompt you to unlock the device, then you can install one of the unbranded S4 ROMs available on sammobile.com. After that, you can put the recovery of your choice on the S4, though I recommend TWRP over the other options.

Thanks for your help. I'm a little confused though, at the moment with this custom google edition ROM it does take my sim, in fact I bet it takes any sim, I heard that was a feature of google play devices. What I meant was after I install the stock ROM will it then not take my sim. So if it has already been unlocked How would I know which ROM to install? As I now know its not a google edition, is it possible to install an official google edition ROM? Do i use this download mode, Odin, or cwm to install a firmware. I'm just not sure what my starting point is. I don't wanna follow someone's guide yet to installing something just in case I'm jumping the gun and need to uninstall this custom ROM somehow.
Sorry for asking questions that I'm sure seem dumb I'm really just trying to learn at the moment I'm green as they come with android. BTW thanks for your suggestions so far, you def seem like you know what you're talking about, cheers

Google Play devices are carrier unlocked, but this is not a Google Play Edition S4. Therefore the device was carrier unlocked at some point in its past. The unknown here is how the original owner unlocked the device. If he or she used the unlocking methods found on XDA there is a chance the lock will be lost when installing a stock ROM.
If the S4 is unlocked, you aren't restricted to a particular region and can install any I9505 ROM using Odin, though I recommend the carrier unbranded ROMs. You cannot install a stock Google Play Edition ROM on the device as the model number of a GPE device is not the same as the device you have. However, you're already rooted and have a custom recovery installed. In I9505 Development here on XDA there is a Google Play Edition ROM that can be installed on your device. Download it to your S4, wipe everything in recovery, then flash the ROM's flashable zip in recovery. I've used said ROM and it works quite well.

OK I have found the 5.0.1 ge ROM , but in there it says I must use latest recovery or whatever plus it recommended one different to mine, is it safe to install using my version of cwm or do I need to learn how to change it??

Deleted by user

TWRP is recommended as there are people who are still maintaining it, unlike Clockworkmod and Philz. While you probably can get the ROM installed using the version of Clockworkmod you have, learning how to change recoveries is useful.

OK thank you for all your help my friend, I will now find out how to do this, I'm sure there is a section on this somewhere, BTW I think you are right about my device being rooted, but I wanted to check and I followed a guide and used super su but apparently its not rooted so I guess something must've gone wrong. Bit scary if I try to change my recovery or my firmware and this causes a brick hmmmmm

It's virtually impossible to brick the S4, especially as the recovery is flashed through Odin.

Phew that's a relief. Thanks man.... Well I'm gonna just risk using cwm for now as I'm new to this........ Thanks a whole lot for your time I really mean that.

I want to, I really do but I'm struggling here. Before I wrote that last comment I tried to find a guide on this forum for swapping to twrp, but couldn't and didn't wanna bug this guy as he had helped enough. Anyway I went to the place he told me and have hit another wall anyway because I don't know how to use the firmware the relevant kernel or the git. My life is so busy and I'm getting about an hour on this subject a day and its gonna take forever lol
If you can help me on my way even a little its much appreciated, I would like to use twrp and the 5.0.1 ge plus the right kernel of course

Follow the Odin guide. It's excactly the same when you flashed CWM.

@Lennyz1988: The S4 was bought secondhand and already had CWM on it from the original owner.
@killfrenzy: Follow the guide Lenny mentioned, but don't worry about the second paragraph. Our device isn't one of those that restores the original recovery on boot.

ok will do, i just tried the app install method but as i suspected, it said root is required for this app and promptly exited so i shall do the odin method, i heard that some people remove root or it could be that it was done wrong. also after reading a few posts here and there i found out that someone had similar issues with their phone random re-booting and they had custom ge with the wrong kernel so it seems once im done my issues should be history if i learn how to install fw + kernel, after this twrp thing i will be one step closer for sure. i also know ppl slate lollipop but once im all done with this im sure i will have picked up enough terminology to install cfw's to my hearts content. hooray for forums and people like you, sounds like im kissin ass but its just gratitude

so using the twrp install guide i gotta install using the odin method i have now got 3.07 odin but this is the next step.........
Odin Install Method (No Root Required):
You will need to download and install Odin on your PC. Once you have Odin installed, download the proper .tar file for your device from the download link above. Power off your device. Turn on your device using the proper key combo to get into download mode and attach the device to your computer via a USB cable. Use the PDA tab or button to browse to and select the tar file that you downloaded and flash the device.
lololol nothins ever simple i see the list of tar files in the link above but no mention at all as to which is the proper .tar for my device, i guess they assume the guide is for people who have done it before. more research tomorrow maybe i gotta be up early ugh

Think you misunderstood, I have flashed nothing yet I got it like this. I'm completely green

Don't suppose anybody knows which is the tar file for my device?? S4gt-19505

OK now I get it, the list of tars in that section are all the same just newer builds of the same version. Seems obvious if you have done this before, but I wasn't to know that and cannot assume things. I'm also gonna guess and say Lenny thinks my s4 needs this particular version for an international, am I right?? Anyway it would've made a lot of sense but how does he know. I have no idea what this phone was I have never owned it new.

Different devices have different codes. For example, jfltexx is the I9505. A T-Mobile S4 would be jfltetmo, and so on.The link Lenny provided is for the I9505. Download the 2.8.6.0 version as its the latest.
As to how you were supposed to know, having never owned one, you weren't. There are tutorials in the General forum though that can help.

[Q] Accidentally killed stock recovery

Hello everyone! I'm brand new to the forums so if I am breaking any rule or regulation, just give me a heads up. So, some basic information about my predicament.
- own a Samsung Galaxy Note 3 from Verizon.
- I use t-mobile network. Works great with no problems.
- phone was successfully rooted via towel root.
I was looking to get cynagenmod on the phone so I started looking up guides and such. Only thing I wasn't aware of was that carrier branded versions can't have their recovery flashed. That said, I used flashify and the clockwork apk. The app did its job, killed the stock recovery, but couldn't load the new one. Now the phone says error, no recovery when trying to access it during boot.
It should be said that the phone still boots and works normally but I really want to get the recovery working so I can at least try again the right way to get cynagenmod working.
My question is, is it possible to get my hands on the stock recovery for my phone and just flash it back to how it was? Basically, how do I fix this problem I put myself in. Of course, I didn't make backups. During the whole process, I figured "if I follow this tutorial word for word, why bother with backups?" look how wrong I was
Any help would be sincerely appreciated. I'm posting this from my replacement phone, not my note 3.

Want to restore my phone to factory but afraid of bricking given circumstances

Android Version: 4.4.2
Rom: XXUGNG2-SHOstock-i-v8.1
Bootloader: I337UCUAMDL
Recovery: TWRP 2.5.0.2
I've been installing Custom ROMs for a while on this phone and the previous phones I've had (Nexus One, Galaxy Skyrocket.) My S4 hasn't had issues installing them until more developers adopted Aurora Installers and now any ROMs that use them won't work. My phone goes into a boot loop and I need to restore my previous Nandroid backup. I thought that my TWRP might be the cause, but it looks like nowadays the only way to update TWRP is through the GOO Manager. Unfortunately for whatever reason that doesn't work properly and I can't figure out how to get it in any other way. So for a while I had this older ROM installed but now that we're well into Lollipop I decided to try another ROM (GOLDENEYE|XXUHOD7 LOLLiPOP TW|5.1.15), but again it had Aurora and failed, and this time it looks like it messed up my bootloader because now I have the unlock icon whenever I turn on my phone (I don't care much about that because my phone is well outside of warranty at this point, but I'd prefer it be removed)
So I was considering just using ODIN to revert all the way back and starting from scratch, but it looks like my phone will be bricked. So basically I'm at a standstill because I obviously don't want to brick my phone, but at the same time I'm not satisfied with my current ROM since it's quite long in the tooth and isn't even Lollipop based. Any help/suggestions would be greatly appreciated.
TIA

One thing you might try here, and another here.

There are flashable zips of TWRP floating around to update and the TWRP thread in our section says to use the TWRP Manager app on the Play Store. As far as using ODIN, you won't be bricked. The unlock icon shows up when it detects the system files aren't stock/root is in place. Your bootloader should still be in tact, and if you can still boot into recovery that confirms it. Either way, you just need to use a different method to update TWRP and you should be fine.

Well I feel like a f-ing nimrod..
I failed to mention in my description that when I first tried to install, not only did I get the Unlock icon, but I got the "Software not authorized by AT&T..." error message that prevented me from doing anything. However, I thought this was related to my phone being carrier locked. I found out later that my phone was unlocked a while ago so that wasn't it. Had I looked more closely at the error I would have seen that it was a Kernel error. Turns out I had to install a LOKI'd Kernel. Not exactly sure why, but that was the only one that worked. Now the new ROM is installed and I'm restoring my apps now.
If nothing else, I got my TWRP updated finally, so I like to think this wasn't all for naught. Thanks for the insight anyways. This was easier than doing an ODIN back and forth.

This is because you're on the MDL bootloader. You need to search the forums for your phone in regard to the MDL bootloader and loki'd ROMs. When you see the "software not authorized. .." message, it just means you need to flash a loki'd kernel for your device. Search for Jeeboo's Recovery and Kernel and you should be right a rain. Good luck.
Edit: I was half awake when I tried to answer your question, and somehow missed that you had discovered the loki'd kernel already. The reason for this is because the MDL bootloader is susceptible to the loki exploit, which for all intents and purposes is the equivalent of unlocking the bootloader. I've been using Jeeboo's recovery for a year or so and never had an issue with any ROM I tried. The kernel cones in handy for those that need a loki'd kernel. There's a ton of easy to find info in the forums to help you get a better understanding of the MDL and how loki applies to it.

Need Beginner's Guide, so Custom Rom can be installed

***UPDATE***
Thanks to reply, I have now successfully done everything I set out to do, and created follow-up guide!
You can find it HERE
Original Post below:
Hello Everyone!
I'd like to start off saying I used to have a Nexus 4, with TWRP and Lollipop-based CyanogenMod. I was able to install this all by myself, and keep both TWRP and the ROM updated. I also flashed custom radio to unlock the LTE capability on that phone. My tool of choice to help customize the phone was Nexus Root toolkit.
I was able to follow guides posted long ago on these forums, to do what I wanted with the Nexus 4 back in 2013/2014, but it seems I'm not so capable these days. I've hit such a roadblock with lack of root and constant stutters/slowdowns with everyday use on my current device, the Axon 7, that I must get away from the stock software. I heard it was not so easy with other devices, and while a few devs have posted wonderful guides for users, it's just not enough for a true beginner like me. From skimming guides posted, it seems like devs already expect you to have installed custom recovery, or unlocked bootloader. Then when I try to do these things, so I can move onto custom ROM, it seems the guides are out of date or just not step-by-step enough for me to use, and I don't want to take a risk and brick my device trying things that I'm not sure about. I'm a power user through and through, but not so up-to-date or knowledgeable enough to be able to follow the guides already on the forums. Consider me 1 out of 5 on tech level for Android software.
Here's the model/software already on my device: Stock everything, from bootloader and recovery, to ROM.
Model: A2017U, Nougat 7.0 on B15 ROM
What I still need clarification on:
with my device already running on nougat, do I need to install the nougat universal bootloader/radio I saw in earlier guides?
will LineageOS have any downgrades in regard to audio quality, on either the headphone output or speakers?
will my ROM of choice have Daydream VR support? if not what would be needed?
this is not a big deal, but do I need a special app or entire custom ROM if I'm interested in a temporary unroot to use apps like Android Pay?
Here's what I want on my device: TWRP, LineageOS with root.
If anyone, expert users and devs alike, could reply with current known-good info about the following, I and a lot of other users would be eternally grateful:
unlocking the bootloader, installing TWRP, and LineageOS, in a stupidly long but simple step-by-step process.
Quick follow-up info:
What I can do so far: download current LineageOS nightly, correct version of root .zip, and TWRP from official websites
NO, I'm not good with using ADB on Windows to get things done. I had to ask a friend to help me install it on windows, the guide he sent was much easier than the one i was using, and he still had to walk me through how to use it once installed to help me unlock bootloader/root on another device, Zenphone Zoom if anyone is interested.
PLEASE, don't link me to other guides for any part of this process, if the steps are thorough and relevant, please copy here, of course with all due credit given to original poster.
Feel free to let me know if more info about my knowledge level or device is needed to help you work on my request.
Thanks for reading, here's to several years more of everyone enjoying this wonderful device!

ok there is three real steps, but it can be aheadache, mainly because you didn't unlock before going to nougat.
Step 1. Downgrade to B29 Marshmallow - go here https://www.zteusa.com/axon-7/ and on the support tab in software updates is a full B29 software package. Download it, unzip it once, then put the update.zip file on your SD card.
- on the phone, in developers options, turn on OEM unlocking (it is needed to flash from sd card)
- boot phone to recovery, choose update from sd card, pick the update.zip from the sdcard, the phone will flash the B29 software. It is a bit slow, let it do what it needs to do.
Step 2. Unlock phone and install TWRP - go here https://forum.xda-developers.com/axon-7/development/edl-emergency-dl-mode-twrp-unlock-t3553514 download the miflash program, fastboot unlock program, and twrp for B29.
- instructions are all there, just do what it says.
Step 3, Install LineageOS - https://forum.xda-developers.com/axon-7/development/unofficial-lineageos-14-1-zte-axon-7-t3545679 very straight forward. Don't forget to install first the bootloader, then the rom, then gapps.
What makes this so hard is not being easily able to unlock in nougat. Most of us here unlocked way before marshmallow

No need to downgrade to b29.

I was thinking this too. Should be as simple as the steps below
1) Flash signed twrp using axonroot tool - this pry's open the door
2) Using twrp, flash fastboot (b20_fbop or something?) - opens door wider
3) Enable usb debugging and oem unlocking in developer options
4) reboot to fastboot/bootloader mode
5) fastboot oem unlock - door is now wide open
Done.

Is that a "should work" or "does work" because I'm trying to root and install LOS also on stock non rooted nougat Axon 7 and so far I've gotten nowhere and no one seems to be able to give me a list that says Yes this works

Help needed
I followed the instructions and is apparently in a boot loop. Initially it was working but now it is not. I can't even wipe the device to start from scratch. Is there another ROM available to try?

Ok, I've edited your post to clear some of the clutter and numbered everything so I can answer everything.
1. No, bootloader updates are only for users who haven't updated to B15 (through official means)
2. Only audio issues are with the front facing speakers. The way they sound is if you turn them up to 100% and then push it even higher to like 140%. So if you keep it at about 71% they sound normal. Check this guide here to get even better quality on overall sound (headphones, speakers)
3.B15 and LOS both work with Daydream. I currently use LOS with my Daydream headset currently.
4.Magisk with this kernel here. Currently have fully functioning Android Pay with LOS.
5. This is a big problem. If you're not comfortable with ADB you should maybe rethink messing with this phone. EDL mode (which is how I flash TWRP and subsequently the B20 bootloader to unlock) is very similar to ADB and the tools needed to flash in EDL can brick your device. Learning how to use ADB isn't bad but it's good as a fallback so you're not relying on strangers to help you out in a pinch (which most will, I just like having the ability to do things mostly myself).

I'll keep on saying this as much as I need to, I get where you're coming from. There's a lot of data about the correct way of doing things. Best thing to do is read and search. When I got my phone B29 was the new hotness and there was a bunch of older data floating around that I had to sift through. But I did it, I sifted and found my own way and combined two different methods to get my phone rooted and flashed with LOS. Honestly, the trial and error, the searching, the sifting is totally worthwhile because while this device is /DIFFERENT/ compared to methods for HTC and Samsung products, it's not harder. It's better to get yourself properly antiquated to the device you plan on flashing/hacking/rooting because there is /always/ a chance for bricking. Then another thread will be created asking for help to unbrick. Take the time, read now, read everything, understand your device, then push forward.

I quoted this because this thread is like the third I've seen in the last couple days. But to offer some help, this is the guide that I've followed with two phones one running B29 stock and one running B15 Stock. It remains the same because of the use of EDL. It's also good in case you want to go back to complete stock (which at the time was speculated would brick your device) but I read between the lines and discovered that it's just not a big deal. Once you get TWRP installed, make sure your Data partition is EXT4, flash LOS, flash GApps and you're good to go.
The hardest part of the process, is getting your drivers to be recognized properly for the EDL flashing tool to work. Anti-Virus softwares tend to throw false positives with tools like the EDL Flashing tool. I installed a fresh copy of Windows 7 JUST to have a flashing station ready JIC. Once I did that, smooth sailing.

I've already used EDL mode from that page to put a fresh copy of stock nougat to, among other things, reduce the potential issues upgrading causes. So all I should have to do is flash B15-NEW_TWRP (Nougat) from that page and then fastboot unlock?
from there reset data/cache, flash custom ROM.
flash gapps
reboot, install apps.

I've already used EDL mode from that page to put a fresh copy of stock nougat to, among other things, reduce the potential issues upgrading causes. So all I should have to do is flash B15-NEW_TWRP (Nougat) from that page and then fastboot unlock?
from there reset data/cache, flash custom ROM.
flash gapps
reboot, install apps.

In case you still need all this, I made a new guide after successfully doing everything:

Thank you for the guide, but I managed to get everything done without having to downagrade from Nougat. I was having issues with my Windows variant recognizing my phone after drivers were installed so I used Linux Mint 18.1 and everything went smooth as a whistle. I think the mods should pin your thread post.

I followed the rootjunkie YouTube videos, worked perfectly and the files were all available.

SOS - OneClick Brick

Greetings,
I need some help. I purchased OneClickRoot for my Verizon S5. Everything went swimmingly right up until it didn't. I got root after several hours with the oneclick tech team. he gave me instructions on how to flash a ROM, but left out the apparently important step where I should have skipped the signature verification. So I had SafeStrap, wiped everything and tried to flash an unsigned ROM. now the phone is dead wit no OS and seemingly no ability to get back to safestrap. Should I just toss this phone in the rubbish and buy a new one or can it be saved? When I boot to recovery, it is Android recovery and it keeps failing on the verification.
All advice is welcome.

I'm unfamiliar with Verizon variants, but have you tried using Odin to flash the original stock?

Yea dude as long as you can get into download mode (or Odin mode whatever you feel like calling it) you're fine just flash whatever version you feel like being on and I would follow these instructions for root and ROMs and possible bootloader unlock since it's Verizon https://forum.xda-developers.com/ve.../testers-required-easier-root-method-t3561529

So Close!!
Thanks for the help. I followed this guide ( https://forum.xda-developers.com/ve.../testers-required-easier-root-method-t3561529) and got it back; ...sort-of.
In Step 13, I used the 6.0 firmware.
In Step 14 I used the "latest stock rooted Lollipop Rom" that was recommended.
I have what appears to be a rooted 5.0 factory rom installed. However, when booting, I get process stopped errors for the first 2 minutes. Maybe 15 or 20 of them. After that, they stop.
Current Problems:
1) the radios are dead. Wi-Fi will not turn on and it does not know that my SIM card is installed
2) when the screen times-out I have to pull the battery to get it back.
3) All the error messages (android.process.media)
4) It does not see the SD card
Questions:
A) Can you help me fix the radio problems?
B) Once I get the radios working again, can I flash any G900V ROM with safestrap and it will likely solve 2, 3 &4?
C) Are the custom roms on 6.0 and higher rooted? I was looking at this one (https://forum.xda-developers.com/galaxy-s5/unified-development/rom-cosmic-os-3-1-t3553838)
Thanks for any assistance you can provide.

Idk if i can help bt i can try haha Well first thing first it sounds like you used marshmallow firmware but then flashed a lollipop ROM which yes it will boot up bt stuff like your radio and GPS, etc won't work so first thing is first i would say is do a complete wipe and get your self back to stock through Odin and get everything working first before worrying about ROMs then I have to ask is what is what is your emmc are you 15 (bootloader unlock and can easily root 6.0.1 or higher) or emmc 11 (can only root 5.0)
