I know there are several threads that will show me how to get back to stock but theyre all at least a few years old. Currently my 5T is running a custom rom based on Android 11 with TWRP bluspark 3.3.1x. Can I just put a full stock zip on my sdcard and flash it in Twrp? Then by via adb or twrp, flash the stock recovery?
My main concern is getting stuck in a place it's hard to recover from. Based on my reading (and from memory) I believe the above will work but I'm not sure which recovery to flash nor am I certain which rom because its been updated. I don't believe I can flash an android 10 rom or recovery to it at this time. That would be for me the simplest solution. Once I get it back to stock I can just do the OTA updates.
The phone isn't for me. I'm giving it to a kid who needs it currently and the rom it's currently running has terrible battery drain. Any help would be greatly appreciated. Thanks
I had heavily modified my phone where my sdcard(internal storage) itself was not getting recognised and has tried custom os like Ubuntu touch and sailfish OS installed. But recently flashed OOS 10.0.1 back on my oneplus5t device. What I did was to wipe partition system, data, cache/dalvik and format data. Then I flashed the rom. When the device started. I did a factory reset again. This worked for me.

Hey guys/gals,
I recently bought a Koodo Galaxy s2x. After a few weeks I looked online and saw that there were some JB Roms for my phone. I couldn't resist and tried to flash one after rooting. I didn't have many problems with it, but there were some glitches that started to bug me, so I decided to see about going back to stock (I should have done this first I know). So then after hours(many) of searching, the best I could find was a T-Mobile stock Rom I decided to try and flash it (both times via odin). I also read somewhere that I should use darkside superwipe to clear my cache, so I tried that, but ever since that CWM stopped working on my phone. anytime I tried to do any back up or anything it just froze, and I had to hard boot. Finally I just tried flashing T-Mobile stock ICS, and Odin said "Failed". I decided to just unplug my phone, as I thought I already screwed it up, but after rebooting, the T-mobile Rom worked. I don't understand why it works fine if the Flash Failed. Now, I can no longer connect to kies (I'm hoping official JB will be shipped soon!), and I am wondering if I can somehow return to a stock Koodo Rom, and if it will connect to Kies again, as it previously had. I have looked a lot and have not found anything that I fully understand. I'm not overly experienced, which is why I should not have flashed to begin with. This is the closest thread I have found to help me, but I don't fully understand what all I need to do:
"Haven't seen anyone shared this yet.
Here's the KOODO ICS 4.0.4 stock ROM I used CWM to flash to stock after I tried the custom ROM.
h t t p s : / / sourceforge.net/projects/koo...d.zip/download
I also flashed DARKSIDE.SUPER.WIDE before I flashed this or you can used CWM Recovery 6.0.1.2 to wipe system and cache."
Is it possible for me to get back to stock phone? and still connect to Kies? and then possibly upgrade to JB through Kies if Hercules ends up receiving it?
Thanks for any help you can give me. Here is all my current phone info incase this helps:
Model:
SGH-T989

4.0.3

Thanks.
If your ultimate goal is to get Jellybean on your phone, check the development section of this subforum. There are numerous stable and wonderful JB roms (AOKP Milestone 6, Liquid Smooth, CM10).
To get back to your stock ROM, download it from here: https://sourceforge.net/projects/koo...d.zip/download
Then, go into recovery (NOT odin), and flash the rom.

That link doesn't work, it says cannot find page. Also, my phone is currently not rooted, does it have to be rooted to flash from recovery? if not what do I do to flash from recovery? I know how to get into recovery, but after that do I use 'apply update from external storage'? Do I have to wipe the cache first?
Thanks.
PS: I just want to be able to get back to stock for now. At least until I learn more about flashing Roms. There is still lots for me to learn, like kernels, radios, Nightly's for official Roms, or even how to properly flash a rom without feeling lost. If I know a way to get back to stock comfortably, It will give me more reason to try some other Roms (once I learn how).
Here is a working link to the stock Koodo ROM: http://sourceforge.net/projects/koodostock/files/KOODO_SGH-T989D_Stock_Signed.zip/download
Are you running a custom ROM right now or your stock ROM? If you're running a custom ROM, it should come with root privileges. If you are running the stock ROM, you can just back it up instead of needing to download the zip from sourceforge. This guide will help you get rooted: http://galaxys2root.com/t-mobile-galaxy-s2/how-to-root-icsgb-on-t-mobile-galaxy-s2-sgh-t989/. After rooting, get into recovery mode (if you can't get the button combinations to work, there is an app. called quick boot which reboots you into recovery/bootloader/etc). If you don't have a recovery or it's corrupt, download ROM manager from google play, and choose the 'install clockwork recovery'. Reboot to recovery to make sure it works, then uninstall rom manager (it's been known to cause bugs if you use it for other things - and I'd recommend other recoveries such as TWRP but it's a bit more advanced). From your recovery's screen, there should be a backup option. Make a complete backup and name it something appropriate. To flash a ROM, download it and put it on your storage drive. Reboot to recovery, and go to wipe. Wipe your data (factory reset), and system (only really need to wipe data in most cases, but be safe). To flash the custom ROM now (or flash the default ROM I just linked), there should be an option to 'install zip from sd card' or something similar. Choose that, browse to your ROM and install it. After installing, go to wipe and wipe your cache+dalvik cache, then reboot. There are several beginner guides sticked in the development forum, along with explanation of terms like radio/kernel/nightly/etc.

Thanks a ton... Worked perfectly! I'm hoping it will connect to Kies once again.. I'll let you know if it works.
Unfortunately, I still can't connect to Kies.. It just sits at the Loading status (for like 10-15 mins). But At least I don't have all of the T-mobile apps and stuff anymore!
Hey I've been reading conflicting information about this, a lot of which was posted more than a year ago, so I wanted to make a new post just to see if there are any ways that are the most popular/easier now...
I'm currently rooted and running CyanogenMod M2. My phone has been having lots of issues no matter what ROM or Kernal I'm running (just battery life issues and just general slowness).
So I bought a new higher capacity battery and looking to just start my phone over fresh, completely wiping the phone's "SD" card. My goal is to completely wipe the phone, install the newest CyanogenMod and a new kernel.
I've heard two more popular ways, one would be to just relock then unlock the bootloader again which would completely wipe it (I'm confused exactly where that would leave me after I unlocked the bootloader again.. what ROM would it be currently running and would I be rooted, etc).
the other is to just completely wipe it using the option in Clockwork Mod Recovery, but I'm not sure how to install a new OS after I just wiped it since the .zip for the new CM would have been wiped when I did that.
Just reflash factory images through the provided scripts by Google - as you may know, they're available for Linux and Windows, then reflash a custom recovery, reboot. Let it boot once, don't setup Google account now; copy your ROM of choice + gapps if needed (refer to instructions on first post of the ROM thread), custom kernel, whatever. reboot to recovery, factory reset, format /system, flash ROM, kernel, gapps, reboot. Wait for it... Done. This is a clean flash. Setup your device.

Was on 4.4.2 stock NJ2...Odin'ed a custom recovery like TWRP...rebooted.....NO IMEI and BASEBAND. That's about as simple, yet complex it gets. Tried reverting back to stock recovery in Odin, only to find that NO IMEI and BASEBAND still shows up. THE ONLY way I've successfully kept the IMEI/BASEBAND....is by keeping everything stock, from recovery to rom. Why would this be? I've even tried restoring the EFS folder....to no avail!!!! I'M FRUSTRATED!!!! My end goal is to be able to flash a rom, use TWRP/CWM, and KEEP the IMEI/BASEBAND!!!
ANY HELP? ANYONE having the same issue or fix?
THANKS!!!!!!:good:
Possible fix...
Make sure you have not used device encryption on the rom prior to your desired rom...
If you have then a device full wipe script is needed to clean up the phone prior to flashing the new rom...
(don't forget to check your SD card for encryption or data files that may be affected)...
Flash TWRP version 2.8.6.0 and flash your new rom....
Higher TWRP versions have been buggy for me...
Best I've got atm....g
It's because you are using TWRP 3.0.0.1, that one is broken
I got my op3 phone loaded up with twrp version 3.0.2-1 but many errors occurred after I flashed this version.
Current problems on my phone right now:
-"The dm-verity is not started in enforcing mode" occurs every time I turn on the phone.
-Twrp won't read any of my files inside the "sdcard" folder wether it's just regular folder, .zip files, and even .img files.
-It also looks like only 1 version works of twrp works on my phone right now since any twrp versions after 3.1.0 causes the twrp program to froze and doesn't completely move past welcome screen of twrp.
I believe I had the same problem. Contact OnePlus on their support page. In a chat support window, tell the operater about your problem, and ask for an appointment with a level 2 technician. They should schedule you an appointment with a technician who should be able to wipe your phone no matter what state/condition it's in. They fixed my phone in a matter of minutes. But PLEASE, try to remember to be respectful and co-operative, it usually gets you better service no matter who you are dealing with.
For dm - verity problem, it's not a problem tough... Just a security breach as seen by Google.
BTW here is the fix...It's easy , follow the thread :
https://forum.xda-developers.com/oneplus-3/how-to/fix-easy-method-removing-dm-verity-t3544339
Can't comment on twrp as I'm on the 3.0.2-1, haven't tried 3.1. Hope it helps, Thanks!
Use TWRP 3.0.4-1. 3.0.2 can't decrypt internal storage, at least not on mine it couldn't.
Also if you have f2fs file system, TWRP takes a loooooong time to boot. Just wait, even though it seems hung. Takes several minutes. If you have ext4, it's quick. Use the app 'Diskinfo' to check
I had TWRP 3.1 and it would not do OTA of lineage, it would wipe the device when I tried and would not restore backed ROMs, stay away from TWRP 3.1. So, i went back to 3.0.4.1 via fastboot. My suggestion is flash the stock recovery from Oxygen 3.8 marshmallow (this can be found in the archived OnePlus 3 tool kit on XDA) and then sideload the stock marshmallow Oxygen 3.2.8 (download from OnePlus support page) and start all over.

That doesn't make sense..
The latest recovery works fine here, atleast the official one. If you are in F2fs and encrypted keep in mind it takes a long long time since F2fs is really bad at this.. Depending in how full your internal storage is it can take up to 10 minutesm
Twrp 3.0.4.1 or
3.1.0 x v.26 blu_spark.
To get OTA you need to be stock, only Oos official stuff.
I do have my oneplus 3 formatted as f2fs, but it is not encrypted. I don't know what happened to it when I tried to do an update with lineage os it basically factory reset the phone (and no I didn't wipe anything but the cache) and it would not install any zips from my internal sd card. I had to go back to fastboot and reflash TWRP 3.0.4.1 recovery. Then I wiped the device and reinstalled lineage, now it works perfectly fine.
They are lineage nighty OTA updates.
Last weekend, I decided to flash a new ROM since the one I have been using is no longer being developed. I flashed a LineageOS nightly build because I used to like Cyanogenmod and heard Lineage is a continuation. I do like the ROM overall, but for some reason it encrypted my phone during install. I did not want it to do this, it just did it without asking me (when I first got my phone, I remember I was having problems with it being encrypted, with my recovery and such).
Is there any way to reinstall LineageOS without it encrypting the phone? If not, how do I decrypt the phone again and get back to basically stock + root? I downloaded the most up-to-date stock 7.1.2 ROM from Google, and was going to just flash that, but it wouldn't let me in TWRP (said the zip was not valid). I also tried rolling back to an older backup (not LineageOS), but the phone never booted.
FYI - I use Linux Mint and have the latest adb/fastboot, and the latest TWRP for Nexus 5x.
Thank you if you can help.

If you want to flash stock rom you have to flash it via fastboot. The instruction is on the Google download side. But if I remember right you have to wipe everything so make a backup of important data.
If I format my "userdata" with fastboot to get rid of the encryption, do you know if it will delete my ROM backups? I think the encryption is why I'm having trouble going to another ROM from LineageOS. I REALLY wish the ROM would simply ask you before deciding to encrypt the phone. I have no reason to encrypt my phone, and I don't want it encrypted.
