[Q] HTC One - Stuck and need help please.

Hi,
My new HTC One's vibrate isn't very strong, so the vendor is sending me a new one. I'm rooted though, so thought I'd better start looking at ways to "undo" the root. When looking at options on the HTC One Toolkit, I "somehow" did something to my phone. All I "Thought" I was doing was getting the version information off it, so I could find the correct RUU, but when trying to reboot after that, it just kept going back to the bootloader with some error like "re-locked" and "security warning".
After extensive searches, I learnt I could flash the unlock.bin file again to unlock it. Done...but then it just sat at the "Slim" logo [ROM I was running]. I could still boot into Recovery (CWM) and tried clearing cache and dalvik - but still sat at the "Slim" logo. So I started digging in. I tried to mount the SDcard in CWM, but wouldn't mount. So flashed TWRP, but same thing there. When I try to mount anything, the only folder it will let me select is "System" - nothing else mounts and my "Storage" reads "0 bytes".
So I thought maybe I'd lost root, everything was Read Only and that's why I couldn't write to anything. So using the HTC One toolkit, flashed SuperSu. Still same thing.
I did manage to adb the slim ROM and the gapps to /sdcard, but when I tried to install, nothing would "mount" in order to install it...so all I got was errors saying install failed, and a bunch of directories that couldn't be "mounted". In summary I've done the following with Fastboot:
Flashed Unlock file
Flashed boot.img (from Slim Rom)
flashed Recovery (CWM first, but now TWRP)
Fastboot Clear cache
But after all that, when I boot into Recovery, nothing mounts and I can't get past this. Any help you could provide would be MOST welcome!
Thanks in advance.
-- Edit --
Disregard - got it finally. Using TWRP, I formatted the data directory, and it was writeable again. Not sure if it helped, but I then resubmitted everything I did in the list above, booted to Recovery, and was then able to adb the ROM and Gapps over and it installed fine. Phew.... Still need to figure out how to get it all back to stock though. That's my next task.

Help - Rooted, failed installing Busybox, now stuck while booting

Hello guys, I really need your help here.
I will try to explain the situation as detailed as possible, if you still need any info, just ask.
I own a HTC One, carrier locked (Base) and not the sprint version, whatever that is.
Yesterday I unlocked the bootloader and rooted the device, following a tutorial by a german tech site. It all went well, everything worked and I was happy. I did a complete backup of the Internal Storage, as accessible by PC. I did also install TWRP and used it to flash SuperSU. I did not do any backup using TWRP.
After downloading a few root apps, a few demanded missing Busybox, so I went to research a bit. I found some installers, downloaded the first one, and clicked install. It said something along the lines of "Install failed, try another location", so I did that. It failed again. I uninstalled the installer and tried another, same result. After a bit of research, I found out I had to unlock read/write permissions for the system partition.
I then found this Thread, telling to flash a .zip file which contains
- Everything necessary to install the latest SuperSU and supporting files (su binary included)
- Install latest busybox in recovery
- A ported wp_mod.ko module for this kernel
- A script to start wp_mod.ko
- A modified boot.img - insecured (allows for remounting of /system to rw when in Android), enabled USB debugging by default, and added busybox run-parts (alows scripts to run during boot).
Without noticing that the title said "Sprint HTC One" and without knowing the difference, I went on and flashed this .zip using TWRP.
The first time, it turned off/rebooted before it was finished (before TWRP showed the reboot option). Turning it on again, it was stuck on the "HTC - quietly brilliant" screen. I held the power button until it turned off, booted into recovery (TWRP) again and tried flashing the .zip again, this time seemingly successful. I clicked reboot, and it again got stuck on the "HTC - quietly brilliant" screen, now I don't know what to do.
After trying rebooting a few times, I did a factory reset, now before rebooting again, TWRP gave me the warning "No OS - Are you sure to reboot?" or something similar, which I find very strange.
Is my backup of Internal Storage of any use? (BTW: I can not access it right now, sadly)
Does anyone know what I could do?
Thanks in advance for all answers.

Long description, but you didnt say what you want to accomplish.
Anyway, probably easiest to flash a custom ROM using one of the following methods:
1- OTG Cable
2- adb push <name of rom>.zip /sdcard/
3- adb sideload <name of rom>.zip

[CLOSED]Vivo XL2 TWRP 3.0 and Root

I must note: I use linux. I only used Windows because SPFT Linux version gave me a chip mismatch error I couldn't fix easily.
1: Please read. It explains what problems might arise. Especially post #6 and #13.
2: There are 2 versions of the scatter file. The MT6735 version is what I used successfully. The MT6737Tmod version is what comes from post #6 & #13.
3: Please use each scatter file to Readback your boot and recovery partitions first, renaming as fit, so you can have a backup BEFORE ANYTHING. Then test unpacking them to see if everything went correctly. Then readback every partition in the scatter file so you don't have to depend on the stock ROM for a backup. I didn't and it led me to take this route.
3: Seem to be a difference in the naming of the scatter file and sizes of system, cache, and userdata inside from the stock ROM and what works..
4: DO NOT choose Format+Download until you know which scatter file works, unless you want to chance a Hard Brick.
5: Wiping the dalvik and cache in stock recovery before flashing TWRP seems to be the best thing to do to avoid boot loops or a hung boot.
THIS ROOT PROCESS WAS DONE OVER THREE DAYS OF CAR WORK, DRIVING, FAMILY, AND COMPUTER WORK. MOST OF THE TIME SPENT WAS THIS MORNING TRYING TO GO TO SLEEP. DIDN'T HAVE TIME TO DOCUMENT AND TAKE PICTURES. THIS WRITE-UP IS FROM WHAT I REMEMBER DURING THIS PROCESS. IF I CAN REMEMBER SOME VAGUE DETAIL THAT YOU NEED, GOOD. IF NOT, DON'T STRESS ME. THE HARD PART IS DONE. A GOOGLE SEARCH OF SOME OF THESE PROGRAMS WILL GET QUICKER RESULTS IF YOU DON'T HAVE THEM. THE MAIN THING NEEDED FROM MY RESEARCH WAS THE SCATTER FILE. LINKS FOR SCATTER FILE AND RECOVERY IMAGE ARE BELOW.
Looking for a way to root first day getting this phone in February. Read this post last Tuesday about MT67xx rooting, thanks lsemprini. Spent two days finding which versions of the programs work with this phone, already had the ROMs, drivers, and tools. Dove right in.
I downloaded the ROM from needrom. Scatter file was unusable. Wrong chip error. Phone reads MT6735 scatter file read MT6737. Did a manual diff. Used SP Flash Tool v5.1524 to flash, formatted instead of downloading by mistake, cord got pulled, Hard brick. Fought with Windows7 to get drivers to recognize a hard brick. Still don't know how I did it but it read then flashed. Looked like another hard brick but SPFT would recognize it for the Memory Test. I just held power+vol_down with just charging block power to get it to come on. Sometimes just one of the buttons was enough to get it to power on and start a bootloop. Took two minutes sometimes. Flashing the wrong recovery led to bootloops. Starting SP Flash Tool and plugging in the USB to the phone as soon as it powers off during a loop will let the preloader "register" and the images to be flashed. Flashing from a stock ROM will lead to IMEI being erased. Used SN Write Tool v1.1716 to write the IMEI numbers. Got them from the side of the box. The MD1_DB and AP_DB files needed are in the stock rom.
Ported TWRP, credit to jemmini for the post https://forum.xda-developers.com/vivo-xl/development/recovery-t3311601. Used that recovery as a base. Ported according to the myriad of guides that I have been reading over the past few days. None of them worked as instructed, had to modify trial and error style. Finally got TWRP to read the internal partitions AND remain after a reboot. A lot was going on when I did this. Not sure if I formatted before, I remember flashing a lot of because of something. I mounted the system just in case & flashed SuperSu from chainfire's website, no formatting afterwards. Rebooted and installed SuperUser and BusyBox. I tried adb and fastboot. They work but not for everything. Hooked phone up to computer with debugging enabled.
Code:
adb root
gives a shell, no errors unlike before. Edit: ADB won't let me start as root anymore.

When i connect the device after clicking download, it says "CHIP TYPE NOT match!"
mind you the device is off, i tried to troubleshoot but still getting the same error.
any help would be appreciated
UPDATE: Im thinking it has to be the scatter file, but im not sure.
UPDATE: I got it to work, after flashing superSU, my phone wont boot past the initial white Blu start screen.

Try powering it off, booting to recovery and then wiping dalvik and cache.
The longest it took to get past that logo was 15 minutes. It is either encrypting or decrypting. Didn't get any type of messages until after root, and those were optimizing messages. Only one came through before rooting when I interrupted the boot process and that was about encrypting the phone. Phone was encrypted before root, now it is decrypted. Could have something to do with that. Try wiping the cache and dalvik after flashing. I actually flashed it three times in a row. The third was after mounting storage then flashing the SuperSu zip. Once you see the next logo with the colorful circles and hear the sound it might be another wait. That is where it let me know it was optimizing.
I must note: Please use scatter file to Readback your partitions so you can have a backup BEFORE ANYTHING. I didn't and it led me to take this route.

Good. I had to name it that because of the chip mismatch error. It was from the V7 ROM. The other two are updates. I also messed up big time along the way. My phone always read MT6735 but it does have MT6737T in different files. I always wondered about that. I got it to work without buying another phone.

It seem that the phone boot logo never goes away. What should I do now?

Hope you Readback your original recovery and other partitions. I didn't and worked hard to get it back. When I just flashed the recovery and something went wrong, it reverted back to the stock recovery.
Try doing this:
1. Start SPFT with the reçovery you want to flash.
2. Hold down the power button. AS SOON AS IT VIBRATES, PLUG THE USB CORD IN.
3. Hopefully you timed it right and it will flash and boot.
Sometimes it took 15 minutes to get past the boot logo.

Here what I did so far
1. Format using SP Flash Tool
2. Download /// By Using Scatter-Loading Files (MT6737T_Android_scatter.txt {From Rom}) Which it check all the boxes AUTO ///// It works but I didn't change the recovery.img like TWRP.img
Download it
It works normal.
___________________________________
But I want TRWP.img to be my recovery for root (SuperSU)
I try SP Flash Tool to change the recovery img to TRWP.img /// Using Scatter-Loading Files (MT6737T_Android_scatter.txt {From Rom}) I UNCHECK ALL BUT RECOVERY.IMG
Before this happen I didn't factory reset or Format anything yet.
It work to Recovery.img but THE BLU LOGO IS STILL LONG
I feel like it not working
Help Help Help ME
Please

Try flashing stock ROM, wipe data in stock recovery, then flashing TWRP, wipe dalvik.
If that don't work, wipe data then flash stock ROM with TWRP recovery, wipe dalvik.
The scatter file from the stock ROM gave me problems. Had to modify mine.
Don't forget to restore your IMEI afterwards since you formatted+flashed.

I will try

The one I attatched on the first post #1 is my modified scatter file. The mods included changing the size to the system, cache, and userdata. Just compared all three. The stock MT6737T scatter file and the V12 ota scatter are the same. The one I changed, MT6735, have the file name, platform name, and partition changes. I don't know why I had to modify it., especially the size parts. It all worked when I did that. I basically gave up on it because of a hard brick. Then I remembered reading MT6735 in some file a few months back while roaming the file system. Made the changes and was back in business. Maybe you need the stock scatter file, here it is.
It's what the end result of this post @ANJIII did minus the size changes..
He just did the name changes and it worked for him. Ya'll seem 180° from where I was.
The second one is from the V12 OTA update. It is very minimal, must be all that is needed for a scatter file. Not really sure tho. Hope it is just scatter file issues.
As long as SPFT is reading your phone, it's still a chance on it all working out. That is how I viewed it.
@andromedaXVIII Don't know if you got it working. This might be a potential solution.

I take it TWRP flashed successfully, it is having a problem reading those four partitons. Possibly encryption is stopping you. Try flashing this in TWRP before anything else to remove the encryption.
I didn't get any errors. I know the userdata partition was different in the scatter files. That could be the reason for /sdcard not being recognized. Must be a difference in the layout of phones, not really sure. My protect_s, protect_f, and nvdata partitions and /sdcard all mount fine, pictures attached. I am able to do a backup in TWRP. I have been playing around with porting different ROMs and came across an issue similar to this. Had to change some lines in updater-script.
I checked fstab.mt6735 file in the stock recovery, the modded twrp3 recovery, and stock boot recovery to make sure I didn't make any typos or leave anything out. They all have the same lines. Had to do this:
Code:
("ext4", "EMMC", "/dev/block/mmcblk0p5", "/system")
in the updater-script I was working on. I got ahead of myself flashing a ROM and was stuck on the 1st logo screen. Held power+vol_down to get it unstuck. Yes I was all calling myself kind of names like I'm sure some people have done following this guide.
Which scatter file you used? Did you do a readback in SPFT with the WORKING scatter file and mount one of those images to check if you can read and write the files. I mounted system.img from the stock ROM to make sure I could read and write the files before I started with flashing. I'm thinking there is are internal differences in the XL2s. You might have to reflash using the stock ROM with TWRP as the recovery with the Format+Download option since you got TWRP installed.
Once I get through playing around with trying to flash this ROM, I will restore and try to find all the partition mappings and update TWRP to work with the format from the updater-script and see if that work. Will let you know what happened.

can you send us your vivo xl2 specs because there are two versions of xl2, V0070UU and V0070EE. Mine is V0070UU. I just did some renaming and editing in the scatter file of MT6735 and it bootloop once after I installed the twrp. I restarted my phone during the bootloop by holding the power button. After that, I opened the twrp to install the supersu then wipe dalvic cache. You may now boot up the phone and it took 10-15mins to use it because the system shows that it optimizes 205 apps(in my case, maybe because I have installed numerous apps). After that my phone is usefull again and I installed V4A because that's the only reason why I wanted to root this phone.

Here is all the information I have pulled so far from the phone. Have a screenshot attached from About device in settings. The attached zip file is all the information I could think to pull using adb . The attached file is my partitionlayout. I just ran cat against every file to see what it would give me and redirected the output. Using adb while the phone is in recovery let me pull and read the files I couldn't while the phone was booted.
@Alexis96312, try to run this command in terminal to get your partition map:
Code:
adb shell "su -c 'ls -l /dev/block/platform/mtk-msdc.0/11230000.msdc0/by-name/'" > someFileName.txt
I have mine listed in the zip file as partitionLayout.txt It will list which names go to what device in /dev and save it in your current directory. The file can be used to get the correct partition layout on your phone. Post the results and I will repack the recovery to see if it will work for you. You can do it also with Carliv Image Kitchen, it has a menu :good:. You will have to modify the fstab files in the ramdisk folder of the extracted image to what the partition map specifies. I went thru all of them to be sure when I first ported TWRP.
@ANJIII is correct about the different versions, nice catch. I forgot about that. I assumed you had the V0070UU version like mine, fault on me for not asking. Mine specifically says BLU_V0070UU_V07_GENERIC 25-11-2016 09:46. I'm thinking the GENERIC part comes from me having to flash the stock ROM. I think it had BLU_V0070UU_V07 with user/keys before I bricked it and had to flash the stock ROM. Got three extra apps that I instantly removed. Seems like the stock ROM function the same as before bricking flashing stock.

It look like the pid:vid aren't recognized correctly. Usually a reboot will help.
Are you connect using adb while in recovery? If so, see if Windows will install new drivers for you. My Linux box read mine as a Samsung at one point. Try running the ls part of the command in TWRP terminal.
This is where I fought with windows when the cord got pulled during flashing. I never got an error like the 2 at the top, always like the bottom one. I kept adding legacy hardware in device manager until one of them worked. The Linux version of SPFT always give a chip mismatch error. Wish it worked so I won't have to boot to Windows.
I kept doing format+download and and plugging the phone in until Windows recognized it because it was in a bootloop when that happened. You need the preloader to be recognized.
Both stock ROMs are on needrom.com. I downloaded the UU version, the EE version is what you might need. I'll pm you a link to my backups from TWRP to see if they will work for you. Same thing happened to me playing with the new ROM. Restoring my boot and system got it back working.

I might need some assistance. (EVA-L19)

After unlocking the bootloader, installing TWRP recovery and rooting my phone with SuperSU (v2.82), I was preparing to install a custom ROM (more specifically the Resurrection Remix 7.1.2.) all in all, things ended up going out of hand and I accidentally deleted my internal storage, losing every single bit of my existing ROM, not to mention the RR ROM file as well. Now when I try to wipe, I can't, it usually says "Failed to mount '/data' (Device or resource busy) and "Unable to mount storage".
I tried using ADB sideload but to no success, only the same message. What I can understand is that the previous data is gone, I tried changing the format of data, system and cache to FAT & exFAT but it still did not resolve my issue.
I'm out of options here, I don't want to have to give up this phone because of my stupidity.
I also tried flashing the LineageOS 14.1 ROM to see if anything was different, here is what it said:
Installing zip file '/sideload.package.zip'
Target: HUAWEI/EVA-L09/HWEVA:7.0/HUAWEIEVA-L09/C432B361:user/release-keys
detected filesystem ext4 for /dev/block/bootdevice/by-name/system
detected filesystem exfat for /dev/block/bootdevice/by-name/userdata
mount: failed to mount /dev/block/bootdevice/by-name/userdata at /data: Device or resource busy
unmount of /data failed; no such volume
Patching system image unconditionally...
detected filesystem ext4 for /dev/block/bootdevice/by-name/system
Script succeeded: result was [1.000000]
Although it said succeeded it clearly did not work and I am sitting without a ROM. I'm not smart when it comes to these things please help a guy out.
(Is there a way to going back to completely stock EMUI 5.0?)
Cheers.

EMUI 5.01 requires encryption, which you obviously removed.
Search for DC Unlocker, it can probably fix it for 25 Euros

I know this is awkward to ask and all, but how exactly do I go about this, I'm pretty lost and I have minimal experience with this stuff..

I never had to use it but here is their portal (with download info, prices, instructions, etc)
https://www.dc-unlocker.com/DC-Phoenix-flash-repair-tutorial
If you search on XDA or search on Google for eg XDA Huawei DC Unlocker you will find threads with first hands experience (I've seen them several tines but didn't save to Favorites)

I'm terribly sorry for being THIS stupid. As I'm looking into this even more, I'm conflicted about the credit amount I need, been scrolling through the list and I can't really find my problem involving firmware I suppose.

People usually buy for 15 Euros. It may help you, Chrome will automatically translate from German

I'm not educated about DC Unlocker but that is NOT neccesary here. You can easily repair the /data partition by flashing the stock recovery via fastboot, formatting data with that stock recovery and then flashing TWRP again. After that TWRP should be able to read the data partition again.
You can easily go back to stock completely and even restore your bootloader by doing a "rollback" to Android 6. (dload method). After that you can normally upgrade from there though EMUI to the latest version of stock.

I've tried using eRecovery to format the data but to no success, I can't even use the touch screen for some reason, (I know about the volume keys, but when it comes to selecting the Wi-Fi, there is no success whatsoever). If you do know a fix for this, could you possibly walk me through this?

UPDATE: I flashed the stock recovery image and it showed me the wipe cache partition and factory data and system reset, I tried both, only the cache one succeeded, the other one failed. I saw a post that directed you to flash boot.img, recovery.img, recovery2.img and then system.img, I did that, but I couldn't boot into my phone - the good thing is however! That I can use my touchscreen in the recovery now.
Obviously the second time booting into EMUI recovery it prompts me to 'Download latest version and recovery', I try to connect to my Wi-Fi, seems okay but then it suddenly fails. More specifically it says 'Getting package info failed'. Save me please :crying:

So this "erecovery" never worked in any way for me (the one which offers you to download the latest version).
Instead you need the normal recovery you already used. Formatting failed for me the first time too, try it again and then it will try to format "low-level" which worked for me.
Go directly into fastboot from that, flash TWRP and go directly into TWRP.
After that should be able to use /data in TWRP. As soon as you are able to start TWRP without any error messages (like "Device busy" or something) go to Wipe and then format data.
Important: check which partition type you have! For EMUI you need "f2fs" and for lineage you need "ext4". You can see and change that in TWRP under Wipe -> "change or repair filesystem".
If you have any more questions, just ask.

So what you're saying is, as soon as I get my data sorted and my partition set to the right one I should be able to install the custom ROM. I could use data and even formatted it, tried installing Lineage but I must've had the storage on the wrong type, now I'm back with the same issue, I'll try to fix it and post my results here. Thank you!

Update: It did NOT work, tried flashing LineageOS through ADB sideload, it was going fine before the bar completely filled up around 50% of the way done, it said 'detected filesystem ext4 for /dev/block/bootdevice/by-name/system' and in the next line it said 'script succeeded: result was [1.000000]'
Help me, I'm begging you, at the moment I don't have an access to a microSD that has the capacity to hold the stock files to do the dload method, therefore this is my only hope.

Whats the error? Why doesn't it work? What happens when you try to boot?

That's what I'm trying to figure out, when I try to boot in it's just stuck on a boot loop. Unfortunate..

Remember that you have to what *a while* for the first boot. Only if you see no change after 5-8 minutes or so something is definitely wrong.
Have you checked in TWRP if your /data partition is ext4?

I know, but it was flashing the Huawei logo and the unlocked bootloader warning continuously. It was set on EXT4 but as I was saying, it said script succeeded at 50%.

That just said that /system partition is ext4. That is default even for stock I believe. You need to check for /data.

I deliberately set the data partition to EXT4 before installing

Can you check in TWRP if it actually says /data is ext4?
Which lineage are you trying to install? Don't you need a vendor.zip for some of them?

/data is indeed on EXT4, and I was installing the one that was on the room section.

XT1900-7 no permissions in TWRP

Greetings.
could not really find anything within this forum that would describe my problem adequately, so I will just ask here, hoping someone had the same.
I recently received this device (XT1900-7), successfully unlocked bootloader and went on to boot and install TWRP.
Booting it temporarily is childs play, but doing anything else within TWRP seems to be pointless. Flashing the TWRP installer results in a bootloop when trying to access TWRP.
To flash LineageOS 16.0 a persistent installation of TWRP is not required (right?) so I really do not care that much about it failing to install properly, I will be just fine with flashing LineageOS from the temporary TWRP.
Here comes the trouble though. I have not yet tried to wipe anything, as I suspect it of not working properly in my case.
Trying to run a backup, something I always prefer to do before wiping and flashing anything, is not possible due to permissions error - it fails to create the TWRP folder. I am also unable to push anything via adb to /sdcard and the contents of /sdcard are rather confusing. There are folders whose names contain random numbers and letters. Checking inside these folders shows that they seem to have an unlimited amount of subfolders.
Opening a terminal in TWRP (as well as adb shell) throws linker warnings (/system/etc/ld.config.txt seems to be missing for /sbin/toolbox) about it being unable to read said file. It does so with every command I submit to the shell.
When I unmount /data I am able to push to the device (though still not to /sdcard - again missing permissions).
Also when switching to slot B it gives me "Error changing bootloader boot slot to B" with "Failed to mount /vendor (invalid argument)".
Relevant data:
I have not done a firmware update, it is still running on Android 7.1.1 and I do not intend to do an update since the stock rom is to be replaced by LineageOS anyways.
As mentionend: XT1900-7, 64GB mmc, 4GB DRAM and so on...
I am able to push files to /tmp for example which allows me to flash the twrp-installer.
Edit: TWRP version is the latest available (3.3.1-0)
Is there anyone who had similar issues and might provide help?
No need to ELI5, I'm at least experienced in Linux, not that much in Android. Previous phone was a G4 Play which was pretty straightforward (unlock, fastboot flash recovery and flash away whatever I felt like).
If you need any more information I will be happy to provide it.
Thanks in advance to anybody that can give me a hint or clue to solve this.

Well. Nvm. It works flawlessly with twrp-3.2.1-1. Seems to be something with latest version. Thx anyways
