Possible Bricked Phone

I am really hoping someone can be of some assistance to me, today i managed to unlock the bootloader, install TWRP and root the phone, i then stupidly downloaded and installed a boot animation from ROM Toolbox lite and went to TWRP and tried to flash it, it came up failed, tried to reboot but it only boots into recovery, tried wiping cache, dalvik cache, factory reset,system and format data and still it only boots into recoverywebt to advanced tried to install it said HTC Dumlock is installed but still boots into recovery,tried reflash to recovery abd restore original boot but still it wont boot up as normal, how can i get the phone to just boot up normally does anyone know?
I am such a twat im usually fairly careful when it comes to this type of thing, it'll be a nightmare if i have to pay to leave it into to get done.

Calm flash a custom rom after a full reset and it should work
If you're having issues putting a rom on your device it's possible through adb sideload with the AIO Toolkit

If you do a factory reset, you remove the Rom element so ideally as I previously mentioned flash a new Rom problem solved

Yeah you need to flash a custom rom - you've wiped system so it won't ever boot no matter how many times you try otherwise

Thanks mate can you be a little bit more specific as to how i can put a ROM on the phone as ive never heard of that AIO toolkit?

If you enter CWM recovery, theres an option called install zip from sideload. Press that and then plug it into your PC, and in CMD type
Code:
adb sideload <location of rom.zip on PC>

I use TWRP i assume that has the same adb sideload?
I am downloading Android Revolution now, so if i create a folder on C drive called c:\android then the ROM is the the img i flash when i open a command?

I presume, I've never used TWRP and yeah correct.

OK i am in ADB sideload now when i open a command and type adb sideload i do not know what else to type, i have saved both the boot img and the full zip file (Android Revolution) in the c:\android folder?

When you type adb devices does your phone show up? Have you installed the correct drivers

see the attached, i aloso tried to drag and drop the boot img to the command window and it wouldnt work, then tried the Android Revolution ZIP and it prompts me to use winrar, wtf am i doinf wrong, all i need to know do i use the boot img or the actual full zip file and i need to know what the exact location to type, i created a folder on c drive called android.
I am in an internet cafe too so i cant stay all day just another hour or so.
thanks

I am gonna have to leave it for now as its doing my head in, i wouldn be grateful if someone could post some specific instructions later and ill attempt it tomorrow, everything appears to be ok when i type cmd then
cd c:\android
adb sideload (what is thew exact name of the file i need to enter)

In the folder 'Android' which you cd'd to, is there adb.exe? And you dont use .img you link to the actual rom zip.

Buddy before anything else could you please put/attach/upload the flashable zip of the bootanimation you got from ROM toolbox?
It is better that we know first what partition it has overwritten so we could distinguish what we need to fix.
I understand that usually the system partition is the culprit but reading from the thread that is all pure guesses. It could be you overwritten a different partition that resulted to this.

Bootloop on chuwi vi10. Please I need help

Hi, thank you for your answer, android kit kat, I've installed a xposed trough an app from the store( Xposed Gel Settings). I've tried the program from this thread: http://forum.xda-developers.com/android/development/intel-android-devices-root-temp-cwm-t2975096 and install drivers but I can't show my device with command adb device, with fastboot device I can show my device but I get an error during the process to flash the recovery, you can watch it on the image. Thank you.

First of all, Xposed is a great danger for unexperienced users. Do not do some "cool things" to your phone without having a backup of your entire system available.
Hopefully you are able to boot into recovery again and restore your backup. If you do not have a backup, do a factory reset (you will lose all your data, but without a backup available...)
If you are on KitKat, install Xposed directly from here.
You can flash a custom recovery for your device by using an app called Flashify.
So my advice for you: try booting into recovery (if you do not know how: search for "your device name" + "recovery volume key". There should be a key combo available to boot into recovery. If this is not possible, make yourself familiar with flashing a kdz file...

Thank you, but my problem is into recovery, when I press and hold power button and +, my device shows me to enter a command with fastboot but when I try to enter in adb mode on windows with cmd my devices doesn't show, with command fastboot my device shows but i can't manage to flash a recovery image for my tablet (the second image), I'm trying to connect with my device trough adb or fastboot on windows, this is my problem. I can't enter to android, remember I've a bootloop and install flashify is not possible.

Finally I found the solution,

Solved. Bootloop on chuwi vi10 after install xposed. No adb or fastboot.
If you can't enter adb or fastboot (remote: unknown command)
You must boot Windows(hold power button and - volume) choose windows with volume buttons and later power button to select.
Boot windows and install ext2fsd http://sourceforge.net/projects/ext2.../Ext2fsd/0.62/
Start the program and you'll see all the partitions. Choose android partition 7gb more or less and ext4 type.
Assign a letter and select the option to mount on the next restart.
Restart windows, now you can enter into the partition on my computer.
Search files called xposed and delete them.
Icon change OS and accept. Boot android normally.

please help installing twrp

i have followed directions to the best of my knowledge, i had twrp already installed but i wanted to update to 20V i was running 20Q, so i used lgup and did a refurbished option. I am running windows 10, i installed minimal adb, adb recognizes my phone, my phone was unlocked and after doing lg up it stayed unlocked, so i proceed to booting into twrp from fastboot, it does boot into twrp i even installed su V279 and updated it thru google play, my problem is when i go to do fastboot flash recovery xxx.img i get writing recovery failed, even if i flashify it does not install twrp i do get root permission according to su. I havent been able to past that, when i try to reboot into twrp with buttons or application phone shuts down and instead of going to twrp lg logo blinks for a second and then phone restarts to normal operation, what am i doing wrong? i been playing on this for days now, thanks in advance
ps, i even installed the rooted 20V from here still same result, unable to flash twrp

weird but i downloaded twrp for 811-815 thru the phone ap, twrp app and i flashed it with same app and it worked, i have no clue what went on, but i tried different downloads and all fail til just now, thank God!

ok please dont do what i did, twrp did flash but it is for 815, i installed it cause app said it was for both, and it wont let me flash h811 files, will continue to work on it, starting from scratch

problem solved, i tried your twrp and had same issue, it will boot but was not writing to phone, i read somewhere, after unlocking the bootloader to save twrp on the phone and then after booting into twrp with fastboot boot twr.img to use twrp file manager and copy from phone to external sd card, i tried that and it worked! now i have permanent twrp. I believe something happens when i tried to copy the file from my computer to my external sd, either my sd card is not working properly and doesnt write everything or some files just dont get transferred cause i copy and paste using file manager app from phone to sd and didnt work. I'm glad i have twrp back in my phone! Thank you raptorddd for helping

yes you need to have both files i use minimal adb so i place one in that folder and other in external sd .. or internal. then selecting install and lower it says image. then it ask you to select. then select recovery and flash install. and youll have permanent twrp.
could it be that you use USB 3.0 or win10.? i know that for KDZ and LGUP it has problems.. your welcomed you should try G5 port rom from astrako.:good:
the h811 vaariant.

I could have been usb3 as you said I was using Windows 10, I had no problems with lg up though. And sure I will try the g5 port as soon as I get a chance, thank you again!

Hello mate
Don't worry.. Just wipe system, data and cache and re-install rr rom. The same thing happened to me when i did a factory reset on that ROM.

i did all, it shows as installing but after reboot goes back to TWRP recovery only

I had the same problem a few days back. I tried everything but at the end, I had to flash the stock ROM using SP Flash Tool. After that, I was able to boot into Stock Android and rooted the phone again and installed the Custom Rom later.

My phone got a bootloop to twrp 3.0.2-7 after I wanted to restore to factory settings (from settings menu), I tried flashing 'new' RR-N-v5.8.5-20170926-aio_otfp-FINAL (during flashing I had 2 errors - logs available), tried to flash with some other roms, I tried to restore some old backups - same thing = bootloop to twrp.

I did not had time to revert rooting and remove custom recovery, so can't say much at this moment.
But your bootloop issue is most probably due to presence of TWRP, you need to completely remove root & TWRP, restore stock boot and recovery, then try.

Fortunately I've made it working again.
What I did, I flashed phone with SP FLash Tool 5.1628 and K50a40_S433_160909_ROW https://forum.xda-developers.com/k3-note/development/official-build-lenovo-k3-note-k50a40-6-t3370537. But it was not success at that time. Phone acted weirdly couldn't boot, only vibration after power on could be felt. So I tried to flash only the recovery Lenovo K3 Note Stock Recovery.img 10,2MB (also in the package but not default recovery image for S433) with the scatter map from S433 stockrom but SPFL said that it didn't end successfully, so I flashed only rocovery from stock rom S433 target_bin folder recovery.img 12800kB and then voila, it started to boot, there was a Lenovo logo, took some time to start but eventually phone is working.
Now I want to root it and / or flash correct version because my phone is actually k50-t5 not k50a40.
So thanks and good luck to those with similar problems after restoring factory settings on AIMROM.

Exactly the same thing happened to me.
So I tried your idea and updated my TWRP, going from 2.8 to 3.1..1
But exactly the same thing happens - it still bootloops, but to the new TWRP.
I've tried flashing several different ROMs that all worked in the past. But no change.

do as what i have mentioned above,..and give update

It worked ! Thanks.
The reason I didn't try it straight away was all the comments about wrong links etc. And some of the links afterwards didn't work. So I was looking for a recovery.img file in other places.
I read your new message, so I used the first link in your post which gave me the recovery img. The TWRP link doesn't seem to work, but I already have an up to date TWRP on the phone.

I've seen you are working with yener90 for this device. His TWRP is valid for F, L and few other variants.
Are you able to let us know if yours is the same? Or still testing and too early to know?
Thank you (I follow you in the OnePlus 5 project too).

"TARGET_OTA_ASSERT_DEVICE := TB-X704A,TB-X704F,TB-X704L,TBX704,tb_x704a,tb_x704f,tb_x704l"
(https://github.com/codeworkx/android_device_lenovo_X704F/blob/android-9.0/BoardConfig.mk)

There's official support now.

twrp-3.3.1-0-X704F.img verified working on a new TB-X704V. Everything seems to be working.

Maybe I spoke too soon.
I tried installing Yener90's Lineage OS 16 image only my TB-X704V device and it failed to boot. That's fine, but then I tried to restore the OEM image that I had backed up previously. Unfortunately, I am not able to get back to a booting system.

Look at the other thread. 3.3.0 works as expected. Use the old twrp for my current ROM or wait for the next update, which will support 3.3.0

I don't have experience customizing TWRP images for specific devices, so let me apologize in advance for my n00b questions...
How similar are the x704f and x705f tablets? I'm wondering if it might be possible to use an x704f TWRP image on an x705f. Lenovo recently released a stock ROM for Pie on the x705f. Now I'm finally able to unlock the bootloader. The previous stock ROM would not respond to fastboot oem unlock commands. I was then able to fastboot flash a bootloader image pre patched with Magisk so now the tab is rooted and happy. However, I still feel insecure without TWRP as it seems to be a key tool that I use for emergency ADB access, flashing, and making nandroid backups. How big of a project do you think it would be to make a customized image for the x705f? Do you think that is something where I would have to start from scratch? Or could the x704f image be used as a template that I could easily modify with information specific to the x705f?
Thanks for your time. I truly appreciate any help or advice you can give me on this.

on my tb-x704f twrp on starts in landscape orientation. the last version i used was 3.2.3 and here i could use both orientations.
i also can't restore an backup because i can't write to the system partition. can this https://forum.xda-developers.com/showpost.php?p=79681018&postcount=259 fix the problem?

No, it won't, it's a magisk module that allows R/W to the system partition after boot up to
facilitate some apps. that require it for full root access.

The problem was that i had no r/w to system partition. the restore works, but the system doesn't start. i have a boot loop with the lenovo logo. i have wiped dalvik, cache and system. after that i also made the normal wipe. then i restored the backup and after restart i have the boot loop. is there anything more to do? this was all i have to do on my other devices.

Sounds like encryption is compromised, restore stock ROm, re-boot and start again.

Hello, I have tried TWRP for TB-X704F on TB-X704A, but though my bootloader is unlocked, I have the latest SDK tools, and fastboot flash recovery recovery.img seems to take, nothing I do causes the device to boot into TWRP. I cannot sideload lineagos using stock recovery, and so for now I seem to be stuck. Any suggestions? I'd like to move past Android 7.1 for a more secure OS.

I've had the EXACT same problem with a TB-X704A. I've been waiting for someone else to say so. I'm sorry I don't have a solution but I'm hoping someone more knowledgeable then me sees our problem. Thanks to everyone, especially codeworkx who does this stuff!

You have to reboot to recovery manually not via fastboot. Unplug from pc and hold power and volume up it should boot into twrp this way cus f version should work

Twrp for tb x704f should work on all 704 versions but you have to boot into recovery manually not through adb fastboot it wont boot up that way for some reason. Let me know if this solves the problem.

I wanted to update from LineageOS 16 to LineageOS 17. Instructions there say to upgrade to latest TWRP (https://forum.xda-developers.com/th...m-lineageos-17-0-lenovo-tab4-10-plus-t4016705). I downloaded the unofficial twrp-3.3.1-0-X704F-20190604-codeworkx.img, flashed using adb, but when trying to go into recovery mode - will not go into recovery. Tries, then reboots again, and goes into LineageOS 16.
Downloaded the "official" version form (https://dl.twrp.me/X704F/), version twrp-3.4.0-0-X704F.img, again flashed using adb - again same results. Cannot get into recovery mode, boots twice and goes back into LineageOS 16.
So - something didn't go quite right - how do I get into recovery mode?

Unplug from USB. Hold power and volume up buttons until the bootloader loads. Use the volume rocker to select "Recovery mode". Press power button to confirm.

I'm aware of how to get into recovery - it WON'T go into recovery. Starts up, the Moto screen flashes, it reboots, Moto screen again, then loads LineageOS. So I simply cannot get into recovery once selecting "Recovery Mode".

What model is your tablet?

I have an A model and an F model. I've used the same TWRP on both the A and F. This particular instance is just the A model - TBX-704A

Not sure of the significance, but "Moto" doesn't appear in the boot sequence of my TB-X704N (changed to TB-X704L after I installed LOS 17.1). I get "Lenovo" in an orange rectangle.
My next step would be to try https://dl.twrp.me/X704F/twrp-3.3.1-0-X704F.img . Better yet would be to hear from someone who's installed LOS 17.1 on an "A" model.

I installed TWRP 3.4.0 on my TB-X704N (Chinese Tab 4 10+ with 4G) three weeks ago. I went on to install LOS 17.1 (https://forum.xda-developers.com/th...7-0-lenovo-tab4-10-plus-t4016705/post81141501). Everything went well just by following instructions. Thank you, codeworkx!
