I have a simple question if I follow the very first way to root my op9 pro, will it wipe my data or my phone will just get rooted with everything intact
If your bootloader is not already unlocked then your phone will be wiped.
The bootloader always must be unlocked before rooting. Unlocking bootloader will wipe everything. Rooting shouldn't reset everything, depends on what you are doing. I never had a one plus so I don't know how it's there, so I'm going from common knowledge. If you are flashing a SU binary zip file from TWRP it shouldn't wipe, but if you are flashing a PATCHED BOOT.IMG may get wiped.

Flashing a magisk patched boot.img on this device does not wipe anything since boot is a separate partition. (Other devices may be different.)
As previously mentioned, unlocking the bootloader WILL wipe everything (the "fastboot oem unlock" step triggers the wipe). However, if your bootloader is already unlocked you're fine, just follow the pinned guide.
One last question, not going to open another thread for this simple thing but can someone help me with a program that will backup ALL my data (gallery photos included) and will restore it when the whole rooting process is done.
Example, iphone has itunes.
So something similar, user friendly

EDIT: What the frick! -.- I fond the answer only seconds after posting this in a thread labeled something entirely different. Oh well. For anyone else looking for the answer to this, my below assumption is correct, aside from having to lock the bootloader again.
More detailed description in this thread.
Original post below:
--------------------
Right, so I rooted and installed CWM on my phone to get rid of that incessantly annoying menu-bar. However, only days after, HTC decided that they'd release an OTA to fix a number of things (internal storage space, for one).
Now, if I've understood this right, there is absolutely no way for me to install the OTA, since I've completely replaced the stock recovery. So what I've gathered from different threads, guides and god knows, is this:
- I need to fastboot write the old recovery back
- Lock my bootloader
- Let the phone update
- Unlock
- Install CWM again
Am I correct? For I am assuming that it's not simply as easy as to flash the new RUU ROM with CWM, since CWM can't access radio, for instance.

You'll find it in the thread I linked.
Or if you want,
1. Do a CWM backup
2. Relock
3. Perform RUU install
4. Unlock
5. Install CWM
6. Restore CWM backup
7 (optional). wipe cache and Dalvik cache
I use this method as your OTA method means losing root and CWM as Unlocking it after the OTA will erase your data partitions.

Yeah, I didn't actually need to lock the bootloader. It wasn't necessary. Flash old recovery, install OTA, reflash CWM, make sure root works, if not, reflash SU.
I ended up having to factory reset on the unlock again. Bad move
Hi all, I have some problems on my gnex.
This happens because I think I have deleted some system files.
1st problem: when I install a rom at the first boot the phone gives me this error: "the application speech engine Google has locked in an unusual way"
2nd problem: when I open camera or gallery the phone gives me this error: "no external storage available"
3rd problem: sometimes the phone gives me the error: "youtube application has locked in an unusual way"
Ok...there are too much problems...just a question now: I want to reset ALL my gnex, I want to delete ALL the files there are in it. I can't do it flashing a new rom or formatting system from recovery. How can I do?
Thanks!
need more details
Without some more details on what ROM you are having these issues with, which recovery you're using, ... it's kind of difficult to help out... That aside, when you flash a new ROM, be sure to first do a full wipe through the recovery. I've flashed my phones numerous times over the years and every single time I had a problem at first boot it was because I didn't do the full wipe. Also, carefully read the instructions posted on the first (and second & third if any) thread, usually the dev explains carefully which steps are necessary to succeed.

That's odd... Maybe something wrong with the device itself in that case... To go back to stock, the easiest way by far is the GNex Toolkit. It has an option to download the Google image & lets you easily flash it.

Well that depends what you mean by that... What it will do is flash the stock ROM that is made by Google onto your device. It will replace the current installed system with the stock one. It will be like when you first got the phone, with the default ICS installed. Obviously a device without a system installed on it would be useless, unless you're looking for a new expensive paper weight of course .
If you still have the same problems after that, I'd recommend returning it to the shop you got it from for a repair/refund. Don't forget to re-lock it though if you decide to go that way .
The problem is that with root explorer i see two folder about storage: sdcard and storage>sdcard0. I think i have deleted some files in these folders. Is there a way to reset their files?
/sdcard & /storage/sdcard0 both refer to the same, namely the internal memory. No way to recover deleted data though. What exactly did you delete??

Flashing the stock image will return all your files to factory. You don't need to delete anything.

Use odin or fastboot. Kits are easier but i trust fastboot above all. And do a backup before flashing anything...tag way can restore. Then factory wipe, then format cache, then go to advanced and format dalvik, THEN flash the ROM

The toolkit uses fastboot... It just presents you with scripted menus and composes the correct command depending on your choices. Makes it a lot easier to get stuff done without having to remember all the different commands .

Without more info on what exactly you deleted it's hard to say. Flashing stock should work for restoring the phone though .

First, you'll need to root your device on stock 5.1.1 BPA1, this guide is fairly easy to follow. Then you'll need to upgrade to 6.0.1 CPD1 and root that too, using this guide. Then you'll need to flash the partial CPJ2 firmware also found here, before you can then flash EmotionOS.
Rooting the note 4 is a lot more work. I loved my note 3 and being able to do it with an app. "Towelroot" it made life so simple. Lol.

Nope, I'm not signing up for issues. The first page talks of re boots, no SMS service, no phone service I'll stick with the sure thing my phone is working I'll be at sometimes laggy but that's probably an overload issue with my apps

ok, so I was able to load 5.1.1, root w/KingoRoot, enable dev mode, install TWRP 3.0.2, & reload 5.1.1, but now I'm stuck in a bootloop.
when I first loaded 5.1.1 stock w/o TWRP, I was able to get out of the bootloop by wiping the system and cache and it loaded fine, but now when I try to wipe the cache with TWRP it gets stuck in the bootloop.
How do I get out of the loop with TWRP?

Pull the battery and SD card, wait for like 30 seconds, then put only the battery back in. Boot into TWRP, pop the SD card back in, use the Advanced Wipe to wipe the SD card and cache, then reboot. If you don't want to wipe your SD, then don't put it back in.

okay, I think I may have lost root after the 5.1.1 reload, in that case I'll start over.

well currently TWRP is what is preventing me from booting the phone, I didnt know if there was an alternate method to "re-doing" the guide without having to start from the very beginning. So long as I have TWRP installed, I can't seem to progress past the second bootloop.
Also Kies 3 is telling me it no longer supports the note 4 because of SmartSwitch (which is not currently installed on my PC) being capable of managing my note 4 now. Not really a huge deal now that I'm downloading the stock 5.1.1 from SamMobile, but that notice struck me as odd that Kies wont touch my note 4, even before all this happened.

No, you need a sd in for the bootloader unlock process. Wipe it, unlock, wipe it, unlock. And wipe it with diskpart. TWRP doesn't properly wipe the card, and will result in a bootloop.
So after multiple attempts and flashes trying to get past bootlooping at the same point, I'm going to take a break from installing emotionOS for a bit, mainly because I havent been able to use wifi now for some reason. at this point im more concerned about getting wifi back.
I've tried flashing numerous times to 5.1.1, factory reset and wiping cache, and after I get my phone back to normal, I try turning on WiFi in the settings and it stalls, it waits for about 5 minutes and then shuts back off, never actually enabling wifi. Please Advise?
Hi guys..!
I'm wondering if this thread is to help about my issue. Please, let me talk about it: I have a samsung note4 sm-n910v in soft brick condition (I think), and was trying to flash it with Odin by 3 different ways: 1- flashing stock firmware 5.0.1 (N910VVRU2BOF1_N910VVZW2BOF1_N910VVRU2BOF1_HOME.tar), 2- flashing with factory binary file (COMBINATION_VZW_FA44_N910VVRU2APB1_VZW2APB1_2932719_REV00_user_mid_noship_MULTI_CERT.tar), and 3- flashing with partial firmware (N910VVRU2BOF1_PartialFirmware.tar). For by 3 ways, my phone is stuck (I can not access to call or text messages). If needs more details, please, let me know. Please, could anybody help me? I'm stuck in explained situation.
Good news update about my issue..! I did a good flashing by Odin few hours ago, just with a repair firmware file for my N910V Note4..!
If somebody has same issue or similar I think him/her could use it to resolve too. Thanks to xda user Trex888 who published the next link to download correct file for my phone: http://www.tsar3000.com/Joomla/inde...ader-csc-pit-files&catid=55:samsung&Itemid=82

Why did you flash such an old version TWRP? That one is from about 3 years ago, and will cause lots of problems!
Couple simple rules to live by, when modding these phones:
1) Do not wipe things in TWRP willy-nilly, without knowing what they are, or what the result will be. The option to wipe "system" is in the Advance wipe section. It's called "Advanced" for a reason. That alone would have been a warning to be careful, and not mess with things, unless you know what you are doing. It also clearly says in TWRP wipe screen, that most of the time, the default wipe (cache, Dalvik/ART and data) is all you ever need. It says that for a reason.
2) Right after you install TWRP, and before messing around with anything, you should make a TWRP backup of your current stock ROM. Definitely do that, before trying to flash root, ROMs, or any other mods. That way, if anything goes wrong (or you simply screw up, and wipe system) you have a backup, that you can easily restore.

In general, you should never flash a file named "OTA" unless you know exactly what you are doing. The requirements for an OTA on this device are steep:
a) Must currently have the version number directly before the OTA number (you can't skip or flash the same number OTA)
b) Must have stock recovery installed (not TWRP)
c) Must match your version (CID, MID). Do you have the Euro version? You never stated this info.

This RUU is only for the US Developer's Edition version M8. Will not work on any other version.
Even if you had the US Dev Ed (which is unlikely) this RUU would require the firmware being flashed, before the RUU will install (thus, Error 155).
In short, it seems like you are just guessing at solutions. Not a good idea.
I've been using the forums for a while but this is the first time I post on here, so I'm not so sure if I'm posting this in the right place. But I need any help I can get at this point.
So a while ago I unlocked and rooted my Moto Z Play by flashing TWRP recovery with the fastboot ADB tools. Things were fine, but then I accidentally let the phone do an automatic OTA update. When the phone was going to boot, it went straight to TWRP recovery and after I input my unlock pattern, it gave me a couple lines of text. In these lines was a red line of text saying "Unable to mount storage" and then it would go to the recovery menu. It won't boot past the recovery anymore.
I looked it up but I can't seem to find clear answers anywhere, as many that I have found have their storage indicating that they have "0mb" when they go to backup. I don't have that problem as all my storage is present and even MTP is enabled. Hopefully someone can help me out here anyway possible.
You can not install OTA updates on ROOTED phone with TWRP recovery.
For working OTA you must have stock recovery and NO ROOT.
If you have XT 1635-02 version, you can reflash your phone using this RSD LITE unbrick tool https://forum.xda-developers.com/ge...orola-usb-drivers-rsd-lite-firmware-t3042687- and you can try to use this firmware for Moto Z Play : https://androidfilehost.com/?fid=673791459329058517

This sounds a bit too hard for me. Usually it is sufficient to flash a firmware with a similar version like you currently have installed, omitting "erase userdata", meaning you do a dirty flash keeping the data.
Alternative, if you want to keep data but erase the phone installing a firmware, you may do backup in twrp and restore data after the phone runs. But keep in mind that a) there were some problems restoring Nandroid backups on Z Play and b) /data/media must be treated separately, which usually is the data you want to keep (mainly: photos and videos you made). You need to enter your phone pin to decrypt data to mount it, maybe that is the missing step.
If you cannot receive OTA updates on a phone with custom recovery, even after (say) restoring a full TWRP System Image backup. . . doesn't that imply, in practice, that you cannot ever return to a stock experience?
I have a stock Z Play with the latest 7.1.1 updates. If I decide to unlock and install LineageOS, there is no way to get back to stock? ever? I mean, I knew about the warranty, that safetynet won't pass, and that I can't re-lock the bootloader. I'm fine with all that. But I thought I could at least get back to the stock ROM, and continue to receive OTA updates. Instead, it sounds like running my backup would be hell: the phone would constantly nag me to install OTA updates, yet if I ever slipped up and said "yes" it would be bricked.
Is there no way to back up the original recovery partition too, so that you can make the OTA updater happy?

The are several easy possibilities.
You can get some firmware which you install using fastboot flash. You may decide to only flash stock recovery. For a successful update you need to have system, boot, recovery, logo, oem (from memory, hope I got this right) in exactly the same version.
You can use fastboot boot to start recovery. Then you should be able to restore your recovery backup.
My usual way: if you have stock, never install twrp. Always boot it when needed using fastboot boot. Then you don't need to care about recovery when updating.
If an update does not work, your always can decide to install a full stock ROM, if you omit the command "erase userdata", your data usually survives fine. No guarantee of course, always do a backup. Don't forget data/media where personal things are stored and never covered by Nandroid backup of twrp.

Aha---great suggestion, thanks! I would never have thought of that, even though I had to do it on another device once where the bootloader kept overwriting the recovery.

I was just reading up on how to wipe and install a full stock ROM (factory image). It seems reasonably straightforward, IF you can find the correct image. This worries me a little, because my device is RETUS and there aren't many of those images floating around. None on lolinet.com for example. Some people say to use a RETAIL image but does anyone actually understand how they are different, and what the repercussions might be?

You may have a look at firmware.center. They have a lot, but I'm not sure if all are working fine. You may need to do a backup and try. But you nowhere get the safety it's right, because Lenorola does not release signed versions (which would also allow relocking).
Note: For me all the firmwares from there worked by now.
