[Q] Bootloop

I tried to flash the bootloader and JSS15R, de-odexed, but it can't get past the bootloop... Any thoughts? No tablet UI mod thing.
Tried to flash this, but it's still won't boot...
Any suggestions?

Honestly I'd use fastboot and wipe the entire device and then flash the factory images. That way everything is updated, you'll then need to fastboot flash a custom recovery.

Just Google "how to restore N7 factory image" and you'll have all the information you need. You'll need either the wifi-only or LTE factory images from Google, so d/l that first.

Ye, thanks, it booted into 4.3 (JLS36C). I found the 4.3 (JLS36C) factory image, but not 4.3 (JLS36R) which is the latest (?)...

Do you know when the OTA for JLS36R started rolling out? If it was recently, like last 7-10 days, Google probably hasn't released the factory images yet, but should soon (assuming everything is OK with 36R).

You will get the prompt for it, but if anything in /system is modified (like if you're rooted, flashed custom kernel) it won't work...custom recovery won't work either. You can flash the stock recovery in the zip that holds the 36C files using fastboot (fastboot flash recovery recovery.img).
On my wifi I had a custom kernel, and when to use the "adb sideload" command to flash the official zip, and it failed due to the boot.img being modified (not stock), plus I had deleted some files from /system/app which it didn't like.

[Q] SGH-I317 - Cannot Get To Recovery Mode

I cannot get my Note 2 into recovery mode. I am able to get to download mode and have tried installing a few different ROMS through Odin. The install results in a "Pass" but the phone does not make it past the Samsung boot screen. I have tried a few of the suggestions on different postings in the forums but haven't had success. I am somewhat new to the rooting community and am in need of assistance with this, I am getting nowhere on my own. Thanks in advance for any assistance you all can offer.

You didn't mention if you ever flashed a custom recovery.

Sorry for the lack of details. I am sure I made a rookie mistake but heres the process that got me to where I am now:
I was rooted on 4.3 (used CF Autoroot). I was attempting to upgrade to 4.4.2 using EZKat's zip file, installing it from an external sd card throuh recovery mode. I did get that to take, but was having issues with the Samsung keyboard crashing (I now know there is a second file that fixes this, but got that info too late). So thinking I had made a mistake at that point I attempted to revert to the stock 4.1.2 rom, which also took. However, I then got a notification for an OTA update, and I went for it (probably a bad choice?).
The OTA update completed but on the reboot it started hanging at the Samsung logo. And that is where I am stuck now. I can get to download mode and Odin still lets me flash roms and gives me a "Pass" but the phone never gets past the boot screen freeze and I cannot enter recovery mode to factory reset or clear cache.
Thanks for your replies, I appreciate any assistance you have to offer.

The first file is a 4.3 rom you can flash but the 2nd file is the bootloader and when I did the ota from 4.1.1 to 4.1.2 you have to flash that mk6 bootloader to make it boot

Just use cf auto root and make sure you get the right recovery and put it in the pda or ap slot in odin or you can flash a stock custom rom that's rooted already like the one I'm on

Note 2 I sent out of state is also stuck. I had downgraded to 4.1.1 to root it and left it there. It did work for a little bit, but not now. Will just flashing the bootloader file do the trick or do we have to flash the ROM too?

If it won't boot on 4.1.1 you might have to go up to 4.3 or 4.4.2 to make the phone work again I tried to go back to 4.1.1 and I couldn't get it to boot but I didn't try flashing the bootloader but it won't hurt anything if it don't work

Just flash twrp recovery and flash my stock backup rom from this thred
It is not rooted full stock
---------- Post added at 05:23 PM ---------- Previous post was at 05:22 PM ----------
Or you can download the full b162 and force install from sd card with the three bottom way

I saw your thread but I don't want to install twrp, unlocked, root etc.
That's why I asked for a full dload version.... Instead my first cast file was C636... If I don't find the proper C636B103 version I will flash again C636B170 to return to my cast version... I just want to have my phone from start...

attempting to root 7.1.1 and maybe mucked it up

Hello XDA,
Long time lurker, first time poster. I decided I needed to root so I can get back some features I lost with the nougat update (wifi hotspot, adaway). Due to not needing my hotspot for a while, I didn't end up trying to root until the OTA 7.1.1 was installed. Here's what I did and where I'm at;
-Followed a XDA guide to root with english twrp (alberto21 was it)?) and SuperSU. Failed.
-followed guide to use chinese twrp. Installed but stuck on boot screen
-kept chinese twrp, flashed to latest supersu, booted but mobile data won't come back on. Regular service works so wifi is okay as workaround for now
found guide saying 7.0 needs a fixed kernel. Before I tried that found another guide that says it won't work with 7.1.1 and to use magisk latest instead
-tried to flash magisk, failed error installing zip file
-supersu fails at extracting ramdisk, which I guess will happen since magisk is failing
-put the alberto21 recovery back on and tried it just for the hell of it
There are so many guides. I feel that if I found the right one and used it the first time, then it would have worked. Thinking that chinese supersu install from recovery goofed up magisk working. Also, every time I go into recovery, it says it was unable to mount storage before I even try to do anything, but it didn't stop the chinese supersu files from writing.
So at this point my phone boots and works except mobile data no longer comes on. I can use wifi to get around it for now. No root obviously. Would like to get root and hope mobile data fixes itself in the meantime. Any suggestions on how to proceed? I didn't find much more doing forum searches but I'll keep searching.
I was going to upload a log file but I'm not given the option to. Maybe cause I just joined?

Check your settings and see if you have your IEMI. Lets hope you have that. The kernal can cause the loss of mobile data, but right now there is no 7.1.1 to flash so you cannot flash a new ROM. Did you make a backup in TWRP?
It is the boot.img you need. Download the latest 7.1.1 ota and see if there is a boot.img. If so, I would try flashing it thru the bootloader and see if that gets you back. Before you do anything be sure to backup just in case.

Also maybe see if there is a recovery too. If so, flash that over the TWRP and then flash back the non Chinese TWRP
---------- Post added at 07:56 PM ---------- Previous post was at 07:50 PM ----------
I checked the 7.1.1 ota and do not see any boot.img. I suggest trying the 7.0 boot.img. Backup first in TWRP.

You could also flash the 7.0 but do not take an OTA. Only way to get back to 7.1.1 is to wait got a full ROM.

I don't care about having 7.1.1 (I don't think) as much as I care about getting my phone working properly. I thought I can't switch roms unless I had root first, is that right? Or when you say flash to 7.0 do you mean something else? I'm way down to stay at 7.0 for a while if it means having a fully functional phone with root.
I used to be pretty tech savvy with PCs back in the day but I'm just getting into the tinkering scene and didn't understand (nor still do) about proper backups. I'm reaching out to anyone who doesn't mind doing a little teaching to help me fix my phone. The mobile data is still not connected, and mobile network state says disconnected under network info screen. Also wasn't able to get root either. Can't sell the phone if mobile data won't work and don't need to sell it if I get root and my data back.
I promise I won't waste your time. I really need to figure this out and learn the safe way to tinker. I won't beg but I will buy the first couple of rounds

No root is not needed. Your bootloader must be unlocked though. I assume if you have TRWP you unlocked the bootloader right? I don't think you can flash anything without unlocking.

If your referring to the IMEI number then yeah I got it. I flashed to english twrp as soon as I read that. I didn't do a backup because I was following a guide that didn't mention it and I failed to tap on the big blue BACKUP button all by myself, but I have one now in case I make it worse.
I have 7.1.1 right now. Wouldn't attempting to flash the 7.0 boot image set me up for a permanent brick?

After this. Be sure not to accept an OTA. We need to wait for a full 7.1.1 ROM before we can do that again.

Awesome, I thought I needed root to do that stuff. I have my bootloader unlocked and the annoying untrusted device boot screen and everything
Soon as I get a chance I'll get on this.
edit: so if I understand this right, I download Blur_Version.24.231.19 (the first 7.0 download in the guide), unzip the contents to my phones sdcard, and use the fastboot command line to execute the commands that you listed?

You will brick if you accept OTA or flash bootloader.img or gpt.bin which is why they say don't do it.
No, you want to connect your phone thru fastboot and have these files extracted to your computer and run those commands from command prompt.

If you do not know how to do that. You need to get the windows ADB drivers. I can get you a guide if you need it.

It worked!
Took me a couple of weeks to get around to it. I picked up a used OnePlus 2 for cheap and have been loving AdAway and being able to freely tether my phone without it telling me to contact my carrier with credit card in hand. I absolutely hate the battery life though. Soon as I see a nice guide to get root on this phone I'm going to try again much more carefully next time.

Done.
Sorry for my poor English
Mod edit: Deleted!

Whaaaaaaaaaaaaaaaaaaaaat - if this is real, awesome job.

Damnnn good..but i'm afraid to try it

Could u explan more
After this ww rom will be installed? What about upgrade?
I mean can i do future update once in convert to ww rom ?

A Video would be nice (not doubting that this simple guide doesn't work) but to proof that indeed this method works) someone please be kind to post a video.
also, does flashing this WW ROM deletes all personal data? or does it flash like an update retaining data?

wow!!
is it works??
and is it without root??

Will OTA updates work on this? Also, could you rewrite the guide some parts are a bit confusing

It works. No OTA from now on though, without a patched boot.img the phone will always go into a bootloop. Some people have reported dead camera after WWE conversion.

"Some people have reported dead camera after WWE conversion. "
Is there more infomation about this? forum link or screenshot?
Thanks.

Can someone state the major differences between the two roms?. I don't see the point of losing OTA and warranty unless you need the stock UI, other than that i don't see any advantages. By the way can someone confirm the call recording option is still there with the WW Rom.

Just to evaluate whether losing OTA is worth going to WW Rom.

Hello Guys, I messed up as I did not unlock bootloader first before flashing it from fastboot. Now I have a bootloop. Can anyone help me how to reflash CN. I have a lock bootloader. Thank you very much.

Unlocking BL also voids the Widevine L1 DRM btw, proceed at your own risk.

Can anyone help me how to unlock the bootloader via fastboot since I cannot get in the software as I have a bootloop. I greatly appreciate it as I have been figuring out this for the past 5 hours. Thank you.

You cannot unlock without the app. Hold the power and volume up key when the phone boots up until you enter the bootloader menu then using the volume keys navigate to recovery option from there just do a factory reset.

Hello Rashad83, I went to recovery and did a factory reset,but it still bootloop. I have a tencent ROG phone II model.

What did you do to get the bootloop in the first place, if you don't mind me asking?

I tried fastboot flash vendor vendor.img then it says parse error due to lock state, then after that I rebooted it then it just bootloop.

just flash newer version ww firmware. Data will keep. a little bit inconvenience that no OTA. but you will always have root (use magisk manager patch the boot.img).
