Reboot and Bootloop (CM10)

Hey all,
I really hope I'm posting this in the right forums, and I did do a google search/xda search prior to this, but I unfortunately did not find anything relevant to my situation.
Anywho, I flashed CM10 on to my phone but ended up in a bootloop. Coming from the S3 and never before using an HTC, I did do the mistake of not flashing the boot.img included with the zip through fastboot initially. After realizing what I forgot to do, I did it and ta-da! It works now and seems to be functioning perfectly.
I seem to have a new situation now though, where my Hox will enter a bootloop whenever I reboot my phone. It's not a huge issue with me, as I can just enter fastboot and flash the boot.img again to get it working. But if I'm not at my computer by any chance, then I would be sort of SOL. So I was just wondering if any of you guys could possibly chime in with a reason why this is happening and how I could fix it.
Once again, I apologize deeply if I just forgot to do something, or if the answer is as clearcut as it can possibly be. Thank you all, regardless.

fastboot erase cache

did you do fastboot boot boot.img or fastboot flash boot boot.img?
sounds like you may have done the first one which would load the kernel one-time and then on next boot it wouldnt be there because it wasnt actually flashed.

I had the same. Just come from Stock rooted Sense 4.1 ROM to viperX. Followed the instructions on their setup but got just a reboot boot loop. If I went to fastboot, shutdown then booted up from cold - no probs. Did the above with the boot.img from the ROM zip, and the erase cache thing. 2 successful reboots later n it seems OK!

Soft brick that wont go away - stock firmware uneffective

So my issue is pretty similar, see what you guys think. i been trying everything i can think of.
i updated from xtrestolite 2.1 to 2.2 with out wiping. everything worked fine except when i would make calls, the other people could not hear me. so i updated the bootloader and modem again (i had done it before) and the problem persisted. i flashed back to stock and was getting stuck at the s6 edge screen. the only way to get around this was and get my phone to boot was to flash aou kernel. i was still having a similar issue with calling so I download a modem from a diffrent server and all of a sudden, it was working again on stock firmware... AWESOME!
now that i had all that done and my phone working as it should, i reset my phone for the first time and i got the FRP lock, wont boot phone because custom kernel. GREAT
I then flashed stock of6 again, the tar ball, and the 4 piece version. no dice
i then found of8, tried to flash that still no dice.
id love to flash twrp and load a rom on, but FRP is a alsjdflajs.
the phone will flash successfully, but upon reboot, it will go into recovery, run its course, reboot, and get stuck that the galaxy s6 edge screen.
i use the vol and power click during recovery to see what its doing and everything seems to go fine. it will then say failed to mount /data. im hoping flashing this with the pit file will work, but i cannot download the pit file from my work computer (hahah its blocks on 4shard and mega).
anyone have any other advice? i will update if i figure it out.
Regards team,
-Mad
p.s. none of this is xtrestolite's fault, that rom has been nothing but good to me.. my phone has been picky though. after 5.1.1 i had to flash a custom kernel in order for the digitizer to function properly.... any help is appriciated guys.

SO UPDATE!
nothing good, i tried the pit with of6 and of8, no dice. still stuck.
anyone got a s6 edge w a broken screen? you can claim it lost for all i care.

no one?
i guess if anything past flash stock firmware people dont know? was hoping for alittle more insight.
im sure if i could flash a kernel i could get it to turn on, but FRP has be at bay...

no help for you bro...Samsung just needs to release there software fixing for this comunity...I'm looking a for a dev to answer my question in this section about just flashing zip files in twrp instead of using odin or whatever other methods that can avoid all these problems that are all similar...hopefully in next few months it will be addressed

Hey mate, try this...

holy... fu34%# /S45it.... IT BOOT?!
after flashing every firmware 100000 times...
THANK YOU!

I initially used odin to flash OI1 update, after a rom I was using caused problems and I got bootloop. It changed bootloader value to b:3 and I'm unable to downgrade now so I used smart switch which didn't recognize device so used emergency recovery and still bootloop. I have factory reset and wipe cache multiple times along with adb side load and individual flashes of bootloader, modem, kernel, flashed custom kernel and twrp to access fix permissions and to mount partitions with advanced wipe etc and still wont boot past logo. Also during one fix attempt phone said can't mount system.. Idk I'm not understanding where the problem is .everything says successful but I'm still in bootloop. Please help. I've spent hours everyday for the past week searching & trying different things that seem might help so open to any suggestions.

bootloop issue?

Hi,
I think I have the bootloop issue. I was running purenexus marshamellow.
At first, I couldn't get past boot after many attempts,phone kept going dark. I wasn't even able to boot into bootloader. So, I removed the sim card to put in a backup phone. The next day I went to work on the phone to see what was wrong with it. Amazingly it booted up. So I connected to adb and downloaded all my personal media (adb pull). At that point I have never read about the bootloop issue, phone has been solid for a while and I don't keep up with the news. So then I decided to do a clean flash of purenexus. I noticed Nougate is available and decided to go with that.
For the most part, I can boot into bootloader without any problems now. So I flashed, the bootloader, the vendor image and radio. I went to reboot into TWRP and I got the bootloop issue. So I decided to flash the latest TWRP. Then I was able to boot into TWRP. I was able to wipe the cache/data. However, when I went to install purenexus, it would freeze and reboot. At that point I realized something is wrong and I came here. I read about the bootloop issue. So now I am wondering if I have that issue? I'm pretty certain I do, except that I can reliably boot into the bootloader. TWRP and android itself will cause reboots, but not the bootloader.
So should I send in the phone to get replaced? Or is there anything else I should try?
Also, I am halfway done towards installing purenexus, is there a way for me install in the bootloader without having to go into twrp?

Help Needed - Bricked

Before I get going - yes I know I messed up. I do have plenty of experience flashing ROMs etc, albeit I'm absolutely not an expert. This was purely a not thinking moment.
So I flashed my Samsung Tab S4 with Kali Nethunter a while back, not really used the tab since. Without a great deal of thought, I decided to put the device back to factory. I went back into the OS and flicked the OEM toggle - utter braindead move. Obviously the device now comes up with a warning, the exact wording is:
"Security Error: This device has been flashed with unauthorized software & is locked. Call your mobile operator for additional support. Please note that repair / return for this issue may have additional cost"
I can still access download mode.
Right, now you've finished laughing/cussing me I did some digging and apparently I can still flash with Odin if its the official ROM? I went to SAMMobile and downloaded the latest ROM and Odin fails with a write error.
What I need to know is:
How bad have I messed up?
Is this recoverable?
Any help appreciated.

Hello there,
So yes, pretty bad mistake but these things happen but it should be recoverable. Just follow the link to get your device booted up! Hopefully the link is for your variant, if not look into installing twrp recovery for your device. Once installed you can back up your data and flash the rom compatible using twrp. Then set up the device and restore your data but make sure it's unlocked or your error may repeat itself! Also you have to find the right version of Odin, they do vary some are patched. Have fun!!
Recovery

Hi,
Thanks for the reply Jedi.
It already has TWRP on it, but recovery is inaccessible since I turned the OEM lock back on. The only thing I can now access is download mode but it can't seem to write to it, which I'm guessing is because the OEM lock is back on. I thought I might still be able to write the official Samsung ROMs even with the OEM lock but it doesnt seem like its the case. Obviously no access to ADB to do a Fastboot unlock either. Fresh out of ideas.
Any other solutions?

bump - anyone? lol, really not looking for an expensive door stop.

It seems you're at the dead end. However, there might be a solution for this, not sure though does it work. But go to OnePlus forum and you'll find how to recover from bricked device. You still got hope because of TWRP. good luck bro

OK, so for anyone wondering if this is fixable, the answer is YES!
You can flash the standard ROM even with the bootloader locked. Clearly what I downloaded from SAMMobile wasnt compatible, however when I used Frija, it found and downloaded the correct ROMs.
Another sticking point of this was the infamous USB 2.0 issue, I assumed the ROM was failing again, however when I finally could be arsed to try it on my old PC, its worked like a charm.
So there you have it:
Latest version of Odin
Latest Samsung USB drivers
Latest ROM downloaded from Frija
Put the tablet into download mode and flash away.

I have hit a wall

Hello everyone, Merry Christmas!
Although I say that, I bring not so merry news. My OnePlus 7T is bricked and after trying everything I don't know where to go from here. Currently I am stuck at the:
The current image (boot/recovery) has been destroyed​phase of things and all I can do is boot into fastboot, that is it.
How did this all start? All I did was just update the phone to Android 12 with the official OTA update from OnePlus, big mistake. Worst update ever; my adaptive brightness went haywire, the brightness gets stuck at max, I couldn't receive calls, data was completely unresponsive, and the list goes on. So before the obvious downgrade method, I try a few things first:
Cycle airplane mode on/off
Reset network settings
Reset ANR
These worked for a minute on my data then right back to the same issue.
Wipe cache partition... Oh wait I had to find out the hard way Android 12 removed this option....
Wipe the phone
That fixed nothing.
Ok time to downgrade, but this is where things got tricky and I realized that maybe all my issues stemmed from me getting the wrong update from OnePlus? Although I found this out too late.
See my phone model is HD1907 which I already knew at the back of my head, but when it mattered to remember the most, I didn't catch what happened. After my update to A12, my model number changed to HD1901 which is the Indian version, and when I saw it didn't think anything of it at the time but then after all my problems it came back to me, my phone has always HD1907 so maybe this is a compatibility issue.
Anyway since I was going to downgrade anyway I thought to myself, 'since I already wiped everything, maybe I can use this opportunity to try out a ROM for A12 and see if it is just this ****ty OOS causing all these issues,' and so I did. First thing I did was unlock the bootloader, and try get TWRP on my phone. That all went fine, I booted into TWRP, flashed my zip for TWRP, then proceeded to try to boot into the OS... and the rest is history because that is as far as I got. Apparently my boot.img is destroyed and I can't boot back into TWRP anymore either, all I can do is get to fastboot.
So then I tried MSM, it won't detect my phone.... So then I tried flashing my Stock ROM through fastboot, apparently I'm missing a partition and it won't write to a critical partition either....
So where do I go from here...?

Hello I was in the exact same boat as you today same phone, same update issues, same no recovery mode, no os to boot into only greeted with fastboot mode. I have resolved it and I'm back on oos 11 good as new. I did use the msm tool it is tricky for sure at first. A critical step is installing the qualcomm drivers and then rebooting your pc. Get them here
https://androiddatahost.com/nbyn6. Be sure to reboot. It's late and I just got this thing back into working shape so I don't want to write a lot a right now. It's been a few days since this post so... If you are still stuck I will be glad to help out let me know. There is hope!

I too had all the symptoms after an update to OOS12, including progressively losing any semblance of booting. not even recovery and the drivers found elsewhere didn't work, and had a different name when installed and would never get detected in the MsmDownloadTool. After installing this one and rebooting, it finally detects it and installs the image of EDL mode.
