Trying to get TWRP working, healthd is not present in stock ROM

Saumya last edited by

I'm a TWRP maintainer for the SM-T110 (Samsung Galaxy Tab 3 Lite), and I'm trying to fix some issues I get while booting up TWRP. The device halts for a while during boot time, and then TWRP starts. https://www.toptal.com/developers/hastebin/raw/afonohadem

I tried getting the healthd binary from the stock TouchWiz firmware, but it is not present in /sbin/healthd where it should be. I've also done an entire find search, and no file named healthd is present. I am stuck on how to fix this. Any help would be much appreciated!

The issue was solved by using SM-T210's /sbin/healthd file instead. The two share the same SoC and the kernels were quite similar so it worked perfectly.

Found the solution in the thing called „internet“: (in the following it is assumed, that all backups are stored to a SD card). TWRP stores backups with a „serial number“ of the phone. i.e. when looking into a SD card, there is a folder called TWRP/BACKUPS. Inside this there are subfolders named after a unique ID for every phone. E.g. CC48TY402141 or something like this. I think TWRP derives this code from the IMEI and possibly from other information on the hardware of the phone. Inside such a subfolder all backups from a certain phone ares stored. To convince TWRP to restore the backup from my old phone to a new phone I had to do the following: I made a backup of the stock software of my new phone. TWRP then created a new subfolder with the ID for the new phone in TWRP/BACKUPS, and stored the backup of the stock ROM there. Then I moved the backup out of the subfolder from my old phone into the new subfolder. After restarting TWRP the backup from my old phone was available and could be restored to the new phone without any hassle.

If you're able to get to recovery mode, maybe you can flash a stock rom or use a backup. You may also be able to use ADB to flash a working rom, this tutorial is for the htc one but it's mostly the same. You can also just keep turning it on I guess, I've gotten lucky plenty of times when a phone that was seemingly bricked and not exiting a bootloop just decided to work one day. Also, if you are having issues flashing roms to your phone you should probably do a bit more research. Using reliable cables, not turning off devices and doing a bit of research into other people who were able to successfully flash and those who unsuccessfully flashed to a device is always a good way to prevent these mishaps as well as fix them. This tutorial explains the process quite well.

This seems to happen if you download the wrong twrp - I had downloaded the S5 twrp. The only other thing to note is when in the stuck Downloading... screen, you can hold Power + Volume Down button to turn off the device.

You can use a SamMobile ROM, but be sure that the model, the country and the original carrier match the phone as different carriers often require different radio drivers if they use different radio spectrum for bandwidth. If you don't know which carrier there are several routes you can use to determine it: find out which radio you have on your device and match it to the appropriate carrier's find out what frequencies your current carrier uses and use that to determine the equivalent carrier for the SamMobile ROMs the version of CM you installed should also tell you which radio is on the phone, on the CM website you can also get the information directly by dialing the code *#0011# on your phone, tho it may not be overly helpful (GSM900 is helpful, for example, but WCDMA is not - if it's WCDMA you'll have to look up the Rx(download) and Tx(upload) to determine frequency) FWIW, I find that Odin generally is easier to use than Kies for flashing ROMs.

Backup stuff with apps like Helium or Titanium Backup. Custom recovery is required, while root is not; however you often need root to flash a custom recovery. Recovery stays in its own partition and will not disappear, unless you deliberately chose not to remove a script that replaces it with the stock one (this mostly happens on stock ROMs). It's usually safe to restore data for user apps; however do be careful when taking care of system apps - especially don't just backup and restore data for Settings.

I would suggest you to try this tool -- Paragon exFAT, NTFS & HFS+ . It is available as .apk files on the net or you can download from Google play as well. But i would seriously suggest waiting it out and doing formatting throiugh tried and tested methods via PC (just to negate any slight chances of renedering your drive useless which does happen when making file system changes using smartphones) here are the links https://play.google.com/store/apps/details?id=com.paragon.mounter

TWRP is not released by OEMs. It is developed independently by volunteers after the device is marketed and it's kernel and ROM sources are released (they are legally obliged under GPLv2.0) . Not all devices have TWRP because they are not suitable for development for technical reasons like bootloader can't be unlocked, SoC not suitable, OEM releasing source late etc. Also, developers make TWRP for devices that are popular and suitable for development. OEMs at times give out free devices to developers to make their devices popular. If you are keen on buying a device that has TWRP support, keep a tab on the device forums on XDA and based on the TWRP /kernel /ROM support from developer community, take a decision to buy or not. This site doesn't give buying recommendations. If you can't find the device in stores, look for alternatives like on line sites etc. Google is your friend. Or else, learn how to develop (this site doesn't support questions on that) and make your own TWRP. Note that TWRP is specific to the device & device variant (Samsung makes several variants for the same model) and you can't use TWRP meant for some other device, irrespective of similarities in devices.

Check your phone whether having enough space for the app. Normally it requires more space than the size of the app during installation. If your phone has enough space, try to clear both cache and data for your Google Play in App Manager and perform a restart for your phone after clearing cache and data. It should work afterwards. Credit to this post. I tried this method and it worked for me Hope it helps

Yes you can boot in TWRP if bootloader is unlocked: fastboot boot /path/to/twrp.img Then you can simply dd whole eMMC or individual partitions. You need some extra memory (on external SD card) to backup whole eMMC or /data partition. Smaller partitions (including the biggest one: system) can be backed up to internal memory i.e. data partition. For Qualcomm SoC: (for MTK devices, path is slightly different) dd if=/dev/block/(bootdevice/)mmcblk0 of=/path/to/external-sd/emmc-backup For single partition: dd if=/dev/block/bootdevice/by-name/userdata of=/path/to/external-sd/data-backup In order to come up with shortage of space, instead of using SD Card you may save backup files directly to PC using adb shell or exec-out. Thanks to @Izzy: adb exec-out dd if=/dev/block/(bootdevice/)mmcblk0 > emmc-backup.img Make sure your adb binary (on Windows or Linux) supports exec-out. Also take care that unwanted non-printing terminal characters don't get included in output. There are also other methods like adb pull, UMS or streaming over network. For details see How to recover a deleted file from /data partition? PS: Another way to save space and to speed up backup process is to backup only the contents of mountable filesystems instead of whole partition image. Particularly userdata and system are larger partitions but they aren't usually completely filled. Mount them and create backup archive using tar so that zeroed out portion of these partitions isn't backed up. Make sure to preserve all file permissions and attributes (whatever applicable depending on filesystem etc.) including classic UNIX file mode and owner, ACLs, XATTRs and SELinux contexts. These options are supported by tar. Otherwise things might get messed up. See more details in How to stream an encrypted backup of the entire device to remote host?

Moto G XT1033 as it seems from this question supports OTG, which means you can connect a pendrive using an OTG cable and store complete Nandroid backup in it through the recovery. Will I be able to return to system with Phone (sim) and Play Store apps working through the "system" backup? I cannot comment anything about Baseband/IMEI issue, but you will definitely lose Play Store apps since they are downloaded and their data stored under /data, which you're not backing up here. On a side note, the device has good amount of Internal Storage available; can you not make space enough to store the backup in it? May be you can try making a backup of /system only and then pushing it through ADB into the PC. Do the same for /data and /boot now. ADB will work in Recovery.

There is nothing wrong with your backup. You are just impatient. Please ignore WARNING adb backup is deprecated... Now Unlock your device and confirm... that is just because the adb.exe doesn't know what's going on at phone side. You should see TWRP backup starting at phone display immediately without any confirmation watch the backup.ab growing until backup process is complete i recommend to backup each partition for it's own, that way you avoid trouble with some old bug TWRP just restoring first partition adb backup "-f twrp_data.ab --twrp --compress data" you can convert that backup.ab later into data.ext4.win with twab.sh (linux only)

Finally I found the solution. The developers of TWRP switched the recoveries for the LG h811 and LG h815 model. So I downloaded and flashed a TWRP recovery under h811 downloads and that recovery works properly on my LG h815.

You need to install custom recovery and flash new ROMs from this recovery. If you choose the correct custom ROM for you phone and follow the developer's installation guide, there won't be any problem. If you wanna know where you can find custom ROMs for your phone, take a look at this question. I recommend XDA developers. You can find a lot of ROMs with user's reply so you can consider before flashing the ROM.
