The phone in question (Huawei G620S) = [G620S-L01] is an old phone, so just playing with it.
A While ago I installed TWRP as recovery. I managed to install Lineage 15. It used to work. Then I tried something (can't remember what, prob some sort of update), and lost of the use of the screen (as in blank pixels, not black pixels), and boot loop.
Recently I've looked at the phone again. I can manage to get beyond the Boot Loop into TWRP once in a while, difficult. Once in TWRP, the screen is still totally unstable (video demonstrates). I manage to navigate TWRP (video explains), wipe/delete partitions. I have a recent Lineage (and Gapps) on SD: lineage-15.1-20200225-nightly-cherry-signed.zip. Also got Gapps. TWRP seems to install zips fine, I then reboot from TWRP menu.
Boot Loop continues.
When I manage to get into TWRP, I also have the phone on usb to Win7. Win7 recognises the phone and I can open the phone memory on Win. I have noticed that the "internal mem" showing on Win is EMPTY. OK, this is probably because I've deleted partitions, etc. But after TWRP has installed zips, still nothing is visible on phones "internal mem" on Win.

G620S bootloop & Using TWRP without screen working properly
I have links to video, pls email or PM me.
Is the screen issue likely a hardware problem? Just bin/throw away the phone?
Is there any other s/w install I can try?

Hi.
I installed some dodgy app which required root access to operate (but it didn't even though I allowed it in SuperSu) and this is where my problems started.
First of all, I noticed each and every app I tried to run would immediately crash. That included system apps, such as the Settings app. At that stage I was left with only the launcher working and attempts to uninstall apps would also cause a crash. Even the shutdown menu was broken and the phone hung up so I was forced to reboot it by holding the power button for 10 seconds.
After that, the phone would no longer be able to boot, it was stuck in a boot loop, but recovery still worked (TWRP for that matter) so firstly I wiped the cache partitions (including dalvik cache) but that didn't help, as the phone still wouldn't boot. In this case there was only one thing left for me to try and that was the factory reset capability of TWRP which claimed to not even touch internal storage so I was fine with that and did the wipe.
Thankfully, the phone booted afterwards and it welcomed me with the first startup guide (the language selection dialog was really buggy but that's Huawei's fault) and the phone was seemingly ok, except that the whole internal storage had been wiped out but not only that - the external microsd card was empty as well! Could you believe that? I couldn't. TWRP promised not to touch internal storage and the external memory card wasn't even mentioned but why would it wipe it anyway?
That's for the story behind it, now for the actual problems I'm facing right now:
The stock remote app is gone
The boot animation has changed to a different one (now it's a silver "android" logo instead of the "honor" logo)
Battery usage stats are not available (see: http://i.cubeupload.com/BXCknW.png)
Sound quality from the built-in speaker seems noticeably worse
Hereby, I'm asking you guys to help me out with all of this.
The "remote app missing" problem could be solved by someone sharing their apk file with me, that's probably the simplest one to fix.
As for the boot animation, I have no clue as I don't even know what files are responsible for that.
The same for the battery stats problem, I'm already through a couple of full-charge-to-discharge cycles as well as wiping the cache partition, but the problem remains.
The sound quality probably has to do with the DTS sound enhancer. The config file for that is either "/cust/unicom/cn/xml/dolby_config.xml" or "/cust/unicomelectric/cn/xml/dolby_config.xml" and I'm asking you to upload these files somewhere so I can compare them with mine to see if anything is different.
The device I'm using is the H60-L02 variant running the B532 ROM.
Does the 3 buttons method erase internal storage as well? I've already set up quite some apps and having to do it again wouldn't be the most pleasant surprise. But at least in this case I could make some backups and whatnot...
Also, would it work if I flashed B535 straight away or does the 3 buttons method expect the same version which is already installed, in this case B532?

It will wipe internal storage. You can flash any *full* ROM as long as you're not moving up or down from kitkat-lolipop/marshmallow.

Okay, so I decided I'd do the whole thing today. I downloaded the full B535 ROM on my PC, backed up all the stuff I care about from the phone to the PC as well, and also I downloaded the MultiTool.
Though the MultiTool thread says this in bold red:
VirusPlus said:
EMUI 3.1 WARNING! Update over rooted or system modded in EMUI 3.1 gives a BRICK.
You have to restore system and REMOVE root before every update in EMUI 3.1 for now.
Click to expand...
Click to collapse
So I also fired up Titanium Backup in order to defrost all the frozen apps, which went fine, and then I wanted to unroot the phone but I've been unable to do so so far.
To unroot, I launch the SuperSU app, navigate to the "Settings" tab and select "Full unroot". The problem being, it just gets stuck on the screen saying "Uninstalling, please wait...". I don't know how long it usually takes to complete, so far I've waited for maybe 10 minutes and nothing seems to change. Should I care about that? Is that warning about updating rooted/modified EMUI 3.1 resulting in a brick still true?
Can I skip this step and just flash the stock recovery followed by the 3 buttons method?
EDIT:
After some trial and error with the multi tool and different recoveries, I was able to finally unroot. Next, I flashed the stock recovery for B532 and attempted to do the 3 buttons method, but it would say "Install failed. The update package does not exist" (could be because I'm doing the update from a USB flash drive as I don't have an micro sd card big enough to fit the package). So I rebooted the phone into system and used the Updater to perfrom a local update where it would let me pick the USB drive. It completed without errors and then rebooted into some kind of updater (black background and some bluish emui colors) where it also took some time to finish thankfully successfully. I can right now see the phone booting and for what it's worth, the boot animation is once again the good old "honor" logo and not that ugly silvery "android" one
And now it's "Optimizing system...". I really hope it finsishes successfully as it's already a bit late here and I wouldn't like the phone to be unusable tomorrow :laugh:
36% ready...
46% it's kind of fun to watch this, and now 49%
I'd like to thank @pudup once more for helping out, I'm not really that much into flashing recoveries, roms and all that myself. Without your help I would probably be too scared to try doing something on my own :crying:
86%, 89%, 95% and 100%. Aww, what a relief Good old stock lock screen and wallpaper.
Hi dear community,
As many other unsolved threads in this forum I'm stock in TWRP and bit lost to the next followable path.
Really weird symptoms :
Digitizer down. Disassembling the phone and replacement with this full parts screen
I take this opportunity to upgrade to the last excellent SultanRom (cm-13.0-ZNH2K-20160808-STABLE-Sultan-bacon)
I perform a clean install (wipe /data and /system with also upgraded TWRP 3.0.2-0)
Then, flashing the ROM, Google apps package, and reboot.
Boot in TWRP. 2 or 3 attempts, still in TWRP.
Open the phone to "see" something
Reboot, 4 or 5 attempts or more...
And TADAM! OPO finally boot in OS.
I reboot to see if problem persist, and same difficulties to boot in OS...
I finally reach OS (I do not know how?! Chance? :crying
I set up and use the phone normally and realise the rear camera is not working. Any rear camera button is present in photos applications, I can not see with "test device" applications. (I had perhaps do a bad reconnecting?)
Another more serious point : the volume - down alone, like a phantom, and SOMETIMES I can't turn off the screen...
I decided to re-open the device, try to fix the rear camera, watch if the volume - is not trapped under the shell.
I also do a full wipe, reinstall ROM...
Now I'm still stuck in TWRP, with fingers crossed to get on the OS by chance!
Any idea? :angel:
I was running KatKiss 4.4.4 on TWRP v2.6.3.0.
Lately it was getting extremely slow. Yesterday I removed some apps I didn't use anyway. I think I removed too much perhaps because today suddenly gapps and many other things started crashing.
I thought I'd just reinstall it, and discovered there's now a KatKiss 6.0.029:
https://forum.xda-developers.com/eee-pad-transformer/development/rom-t3318496
so I downloaded it, and all the other files, rebooted into TWRP and wiped, and tried the install - it just left me with a boot loop. Ugh.
Got back into TWRP and happened to format everything. Then I installed Universal Naked Driver 0.72 in Win10.
Current behaviour:
Regular reset: boot loop.
Power+up: APX mode.
Power+down: tiny menu, then boot loop after cold boot.
Power+down+up: TWRP.
EasyFlasher asks me to go into APX, then I select one of TWRP 2.2.1 and RogueXM and Roach CWM and even the WW_epaduser9_2_1_24UpdateLauncher.zip file, but in all cases it's just the same. There's some text output, then suddenly a 0.001ms black popup disappearing before I can read it, then the regular window says OK. BUT... there is no change at all.
Any idea what I can try? I searched a lot before deciding to ask here.
The KatKiss link above assumes that the files are already inside the TF101.
How do I put the files into the TF101? What is the next step?
After mannnnnnny hours, I actually managed to install and run the Asus ROM.
I went on to TWRP 2.8.1.1, KatKiss 6.0.029 and the belonging files. Now it's booting up Android, but... not very far.
It keeps complaining with many popups "Google Play services stopped". Is that normal for a fresh ROM?
I add Wifi - then it gets stuck on Checking Connection "it can take a while". It's now more than half an hour. How long is a "while" normally?
I gave up on KitKat 6 and went back to 4.4.4 which then starts.
Still the weird frequent popups "Google Play services stopped".
Reinstalled three times now (KitKat and gapps) and still the same problem.
Could this be a hardware problem?
Well, for all you who read all the above (no one? lol), it is not a hardware problem. It's google messing up: https://forum.xda-developers.com/ee...google-play-services-update-breaking-t3555444
I am running stock ROM and have bootloader unlocked and TWRP already installed. The phone was rooted without problems. I was getting an error from Super SU, so I looked up how to fix it online and the suggestion was to install an older version and then try to upgrade it. It was hard to find a zip from a legitimate source but once I found it, TWRP did not show the directory I was looking for (this was previously available when I rooted it). This is where I did something stupid and looked around in the settings and found the Slot A / Slot B option. I switched from B to A and the phone got stuck on the boot animation for several minutes after rebooting. I decided to reboot into TWRP and switched the slot back to B. This brought the phone back but WiFi is off by default and whenever I try to turn it on, it doesn't change.
I have seen a couple of other people mention similar issues about losing wifi after a root or changing the slot. What's the fix? I am wondering if there is anything else "broken" after the slot change and if I should do a factory reset (I would hate to do that as I was almost finished setting up this device). I have also received the error message saying "Process System isn't responding" in the settings menu a few times. It also seems like the finger print scanner isn't recognizing fingerprints any more and face unlock isn't working
One possibility is, that SuperSU isn't that compatible anymore. Magisk does a wonderful job and no problems so far. Maybe you should give it a try and switch from using SuperSU to Magisk.

I had the same issue when I first got my 6 when I was playing around with the slots. Also my original TWRP install for some reason would crash and reboot whenever I plugged in the data cable while in TWRP. I ended up flashing back to stock OOS 5.1.5 through fastboot (used the flash-all command) and then reinstalled TWRP and everything has been working great since then.

The instructions I followed already installed Magisk to the phone. I wanted Super SU because some of the other chainfire apps like Liveboot and rooted apps like Titanium backup said Super SU is needed (Titanium said Magisk will work but may not be reliable for some newer versions of the ROM). I can live without liveboot but really need Titanium to reliably transfer data from my older phone.
To be honest I didn't know they did the same thing (magisk and Super SU). I am curious now, what if I factory reset my phone and attempted to install Super SU instead of Magisk this time?
If I do a factory reset (let's say I want it just like it was out of the box and I format the data partition as well), will I need to root the phone again? I am asking because I don't know which part of the instructions I should ignore. I am sure TWRP will already be installed after the reset so I would only need to install the extra apps...
You don't have to format data. Just factory reset it. Then use "fastboot boot twrp.img", don't allow modifications, flash a kernel you want (if you want one - I really recommend ElementalX) and then the latest version of Magisk (16.4 BETA currently). Did so - all fine. And yes: Even Titanium Backup works without any issue with Magisk.
We had similar problems with TWRP on the Razer Phone when it was new. We solved the problem by using the TWRP boot image to flash the stock boot image and then flashing a TWRP zip. I just got the OnePlus 6 yesterday and haven't really messed with it yet but everything sounds the same to me so far.
I read more about TWRP and realized what I was doing wrong when the directory with zip files wasn't showing up. When TWRP showed up I was supposed type in my regular unlock password to decrypt storage. When I did that the folder I was looking for showed up. I made a backup through recovery (which took like an hour, may be because the external flash drive I attached was really slow - and the size of the backup was about 12GB). After that I installed the zip file for Super SU, just to see if it worked - it showed the installation was successful but the app was still missing from the app drawer. Now I wanted to factory reset the device and start over.
I went into wipe and there was nothing listed under the wipe screen. I went into Advanced wipe and wiped whatever was selected by default. The selected items were Dalvik / ART Cache, System, Data. There was also "Internal Storage and USB Storage" that wasn't selected.
I swiped to wipe, it wiped everything. Then asked reboot, I rebooted, got a blank screen with white LED for a long time. When I plugged it into the computer it recognized the device as Qualcomm HS-USB Diagnostics 900E (COM4). I rebooted it by holding Power + Volume Up + Volume Down. I tried to boot into boot loader next. This brought me to another blank screen. The computer still makes a noise when it reboots but screen stays black. The only message that shows up is the one saying boot loader is unlocked. Did I brick my phone? This keeps getting progressively worse.

OK good news! I tried one more time and fast boot showed up. I was able to get into recovery. I have the backup so I will try to restore that. I don't know what to do after that. I am thinking wiping without getting into advanced mode.

When your phone booted straight into that mode with black screen and the led, then you bricked it. Same happened to me 2 days ago. The solution was to use the Msmtool from another thread and it worked great. Just follow the guide. But it will wipe your device. And you have to install oxygenos manually via "local upgrade". If you have a question, just ask
What I ended up doing was restoring from the backup I had. This was the "bad backup" without WiFi and broken finger print and facial recognition. After the restore, I did a normal wipe (not advanced). This reset the phone to factory settings. Once I configured WiFi and signed into my Google account, Google offered to recover from a cloud backup of my One Plus - I didn't know Google made these backups. It downloaded all the apps automatically. I don't know yet if I have sign into all of them all over again.
The bad back up saved my ass, I wasn't even planning on making it. I was just testing the backup feature. That's why you should always do a backup, even if the device isn't in ideal configuration.

I rooted my phone with Magisk and installed the 5.1.6 via OTA (and reroot via installed Magisk Manager). So no need to install TWRP so far.
Titanium Backup runs flawlessly with Magisk (already on my OP 3T and my OP 5).
So give Magisk a try, I never had such an easy and reliable update as the one from 5.1.5 to 5.1.6
Helium is a great alternative to titanium.
Hello everyone,
This is my first post on this forum, sorry in advance if the format is not correct.
Here's my problem: I was given a SM-J710FN that displayed an overheating problem on the screen while the phone was not heating at all, as well as buttons at the bottom of the phone were not working anymore.
I reset the device to factory default, erased the data from the recovery mode and flashed the 8.1 Oreo version with a ROM STOCK J710FXXU6CSK1
After all these manipulations, the buttons still did not work and the overheating message still appeared, preventing the phone from being charged even when it was switched off.
So I thought of programmed obsolescence, and thought it was worth trying to downgrade the phone to 7.0 from version 8.1.
Could you help me on this subject and tell me what you think?
Sorry for the up
try flash a custom rom, it does not need buttons, like this https://www.google.com/url?sa=t&source=web&rct=j&url=https://m.youtube.com/watch?v=veWLleEULe4&ved=2ahUKEwigx7TjmoTvAhVUIIgKHWbJCjIQ28sGMAJ6BAgFEBc&usg=AOvVaw3xJ6phS4kotjx4fk6Ypfuq
home button work or not
Thank you for the answer, I really appreciate it
Here is the update since I followed the Youtube link you sent me:
I have transferred the Custom ROM (Pixel-AB-11-20200909-ErfanGSI.img-0125.7z) as well as H-VENDOR_V1.0.zip to the mobile phone via a USB cable plugged to my PC in the root of the phone in order to proceed to its installation.
I then used Odin to flash Orange Fox (also TWRP on other attempts) with AP, but when I get to the Orange Fox recovery screen, the .zip files do not appear in the files. When searching on the Internet, it is advisable to flash via Fastboot, but despite several attempts, I cannot detect the phone with Fastboot, but only ADB. Even the manipulation saying to install the drivers manually from the device manager doesn't work because a message saying that the file to be used doesn't contain a driver is displayed. (android_winusb.inf)
And I also notice that after having flash TWRP or Orange Fox, the phone can no longer boot on the system.
Have you got any advices?
I continued my tests on my side, I was able to better understand how TWRP and Orange Fox work, in fact to make it usable, you first have to FORMAT the /data (not swipe), so, make TWRP / Orange Fox operational.
I was then blocked during the installation of the personalized ROM with the error of the /vendor, following my research, it would be necessary to install a .zip dedicated to that (Mokee from what I saw)
But I did something I shouldn't have done, and I flashed the zip "twrp-3.2.1-0-20180414-codeworkx-dumpling" from the Orange Fox recovery, and since then, the phone is stuck at startup, and when I try to access Download Mode, I get stuck at the Warning Message because my volume buttons don't react.
Is it possible to do something about it or the phone will be forever bricked?
