[Q] Wifi Model, Stuck on Google Boot Up Screen, No OS Installed says TWRP, help?

Hey all,
So, my smart self was attempting to flash Marshmallow 6.0 from 4.3 (rooted)...I did the same thing that was here on this THREAD and now my tab can only go into TWRP, but there's no OS installed because I wiped (and didn't make a darn backup....), but there are a few differences from the thread I referred to:
- I can get into my Bootloader
- I can get into TWRP
- I have the current TWRP 2.8.7
- I've tried the Nexus Toolkit from HERE, my device serial is recognized, but it states that I'm offline
- Because I'm offline, I can't push any files to my device through the tool
- When I'm in TWRP, my computer will recognize my tablet and I can actually get into folders and what not, but I can't copy/paste any files to flash within TWRP and I get an error
- Anytime I power down or reboot within TWRP, it tells me that I have No OS installed
- I can't use ADB (as far as I know) because my device shows that it's offline
Is there any hope that I can recover even back to 4.3?
Any guidance would really be appreciated. I have to step away because I'm frustrated and am angry at myself that I didn't make a nandroid.
Thanks in advance.

Are you using stock rom? Because if you are, I wouldn't even try. What with the widespread knowledge that stock might brick, some people insist on it. Otherwise, if you can get to the bootloader:
(1) Make sure it's unlocked (if you're not familiar, connect tab to PC, make sure fastboot works, then enter "fastboot oem unlocked" without the quotes then follow instructions on your tab);
(2) Flash bootloader 4.05 if you haven't already;
(3) Get a USB OTG thumb drive (you might need an OTG adapter for this); and download a Marshmallow-based custom rom in the Android Development section;
(4) Get into TWRP and mount USB OTG. You should see all the files on your thumb drive;
(5) Copy all data you care about to your PC;
(6) Wipe everything except USB OTG twice. Then go to Format and do it twice too. If yours is 32GB, it will take a while (30 Mins average depending on how much data);
(7) Flash rom, then Gapps.
You should be able to boot after that. Good luck.

Thanks for this! A few questions...
- Before I wiped my OS, I was running the Smooth ROM. Does this make a difference? - Regarding fastboot, how do I get into it? I can't use adb because it lists my tablet as Offline when I type in "adb devices"...
- My lock icon is unlocked at the Google screen, but it stops there since I currently have no OS
- Would I be able to skip to your Step 4 just use the USB OTG and mount the original 4.3 OS through TWRP?
- Should I just flash the OEM 4.3? Or should I load the Smooth ROM or whatever other ROM instead of the OEM 4.3?
Thanks for your continued help!

It shouldn't make a difference what rom you flash now so long as you wipe and format everything inside TWRP. But you must make sure you have bootloader 4.05. 4.02 will not allow you to flash LL or MM successfully, and the system does not upgrade on its own no matter what rom you're flashing now.
Since you said you couldn't get TWRP to copy anything, I suggested that you use a thumb drive. Basically, if you turn the tab totally off, hold power + volume down for a few seconds, it should take you to the fastboot page (pic). Look to see what bootloader version you have there.
From here, you can basically flash anything. I recommended that you wipe and format first with TWRP because it happened to me a few times when for some reason, wiping alone still left some residual data that interfered with flashing newer roms.
Stay away from anything stock for the moment. God knows it has bricked more than a few devices. Download SkipsoftToolKit and flash from the fastboot page if you want an automated process. It has worked wonderfully in my experience. Ask if you have more questions. Have fun.

This is really helpful...I think I'm almost there.
I'm on a super old Bootloader (see attachment) so I'll need to update. I downloaded the update from this XDA Thread
More questions:
- Would I be able to push the 4.05 bootloader update and custom whatever Marshmallow ROM via the toolkit instead of from a USB OTG?
- If I was rooted on 4.3, am I still rooted so that I would be able to flash the custom ROM? I don't want to risk doing further damage, lol.
- I'm not home at the moment, so I can't test this out -- I'm thinking I couldn't put anything into my tablet last night because it was running TWRP and I didn't have it on the Fastboot screen. Would being in the Fastboot screen possibly allow me to copy/paste the zip files into my tablet?
- If there's nothing I need to copy from the tablet, would I still need the USB OTG? Or could I just use the Toolkit to push everything into my tablet and flash via TWRP?
Based on your answers to the above would this be the correct order:
1. Push 4.05 bootloader update and custom ROM via toolkit to my tablet
2. Flash 4.05 bootloader update within TWRP
3. *Per your earlier advice* Wipe everything except USB OTG twice. Is this cache, dalvik, system, and data? Or literally there's an option for "wipe everything" (I don't remember what I saw)?
4. Then go to Format and do it twice, too. I have a 32GB, so I'm expecting it to take awhile for the format
5. Flash ROM, then Gapps. I don't have any apps I need to put back so much as I need an OS to load, so I can add later.
Thanks again for everything!
EDIT:
Okay, so I came home and was able to use the Toolkit to recognize the device in fastboot mode. However, I wasn't able to push anything into the phone because the Toolkit said that I needed to be booted into Android.
The last thing I saw when I was in TWRP poking around was that I saw that I could install .zip files from USB OTG. Are either of these alright for me to connect my flash drive to and be recognized inside TWRP?

If you're comfortable using the ToolKit, you don't need an OTG cable. Connect your tab to PC, fire up ToolKit, complete all the prelim BS, then flash the bootloader from TK. Do not use TWRP for this. To do this, open the ToolKit folder in drive C:, locate the folder therein for zips, place the zip files (4.05 bootloader; TWRP; or custom roms) in there, and start to install. I am talking off the top of my head. But give me a few minutes to check the Kit again, and I'll give specific instructions. Bear with me, as I'm on Linux at the moment and therefore cannot start ToolKit (which is in Windows).

Things to do in order:
1. Download bootloader 4.05 (flashable zip HERE); and custom rom of your choice (zip format)
2. Locate the Unified Android ToolKit on drive C: on your PC and open it;
3. Locate the folder “put zip file to sideload here” → “Nexus 7 2013” then paste
bootloader zip and Rom zip in there;
4. Fire up Toolkit with tab connected; complete all the prelim questions;
5. Follow all the steps to install TWR 2870 (pic 8, choice 6);
6. Go to TWRP, wipe and format.
7. Go back to TWRP main page → “Advanced” → “ADB sideload”;
8 Go to ToolKit (pic 8) enter choice 16 (Look at the pics that follow for the correct choices) to
sideload Bootloader;
9. Flash Bootloader.
10. Go back to TWRP main page → Reboot → Bootloader. Once there check bootloader version 4.05;
11. Get into TWRP to sideload Rom; flash it.

Wow, this is awesome. Thank you so much.
I had already flashed TWRP 2870 before I wiped the OS, but I figured I'd try again using the Toolkit, but I got an error. I stopped here just in case.
Earlier, I tried flashing the zip for the bootloader the same way you just instructed, but my serial number turned into question marks?
Please see attachments. My pics are on the right side of the comparisons and I blacked out some of my serial number just in case for the TWRP pic.
Thanks again for the continued support!

Ok. One step at a time. Since you don't have an OS installed, ToolKit cannot complete the process of sideloading because it normally would have to use ADB from within the OS (which is absent) to restart the tab into recovery mode (TWRP). But if you're already in sideload mode within TWRP, it would detect it and transfer the file over to your tab. Let's go back.
(1) Fire up ToolKit (TK), go to sideload step, type the file name and stop. Get to fastboot page on your tab. Go back to TK and hit enter. TK should detect fastboot mode, download TWRP 2.7.1.1, take the tab into TWRP, tell you to go to sideload mode. Thereafter, it should detect this mode and transfer the file over. Then TWRP would flash the bootloader 4.05 automatically. If successful, sideload the rom the same way to flash it. Then upgrade TWRP back to 2870 with TK.
(2) Failing the above (because TWRP somehow doesn't function correctly), put the tab in fastboot mode, go to TK and follow the steps to flash TWRP anew. TK should detect fastboot and begin to flash the recovery. That done, go back and restart (1) above.
(3) If that still doesn't work, we have to resort to fastboot.exe and do it by command lines. But that's far ahead. Try the above first. We'll cross that bridge if we get to it.
I can send you an automated package that would upgrade the bootloader to 4.04 that I downloaded a year ago from Scott's Roms (thanks to him). It's good enough for Lollipop 5.1. The file is about 4MB and I'm not sure how we can do this through XDA. But if we ever get there, I'm certain we'll find a way. And smile, it's only a lousy tab.

Let me just say, I'm so thankful for your help in all of this. Seriously. Thank you.
I kept on tinkering with the ToolKit and Fastboot kept on stopping everytime I switched to TWRP. I got to the point where TWRP showed 2.7.1 but the ADB Sideload kept getting stuck at the "Starting Sideload" prompt.
I went out and bought a $3 OTB USG cable and figured I'd give it a go since this sounded easier (theoretically). At first, I couldn't understand why the OTG wasn't recognized within TWRP. Then, I realized I needed to mount it within TWRP.
Once it mounted, I wiped and flashed the 4.05 bootloader zip. Success.
I went back into the Fastboot screen to verify 4.05. Success.
Went back into TWRP 2.8.7 and flashed a 6.0 ROM from these boards. Success.
Flashed Gapps. Success.
Rebooted. I'm now running a custom Marshmallow ROM and it runs so smoothly now.
Seriously. Thank you.

I'm glad you got it working again. Sorry you had to make a trip to the store. You should've waited for KT to switch the tab to TWRP 2711 for you. But it was not a waste of time anyway.

Device not detected

Hello everybody,
Here my problem :
I tried to install a custom rom, I failed. Now, my smartphone stay on the Asus logo screen. I tried to follow this - http://forum.xda-developers.com/zenfone2/general/guide-to-apply-ota-bootloop-rooted-zf2-t3127835 - to fix the problem, but when I connect phone and laptop, adb doesn't find the device.
If I continue and go in recovery mode (using TWRP), laptop can access the phone (I can see internal memory but not external).
And if I try the ADB sideload, there is no device again...
It's the first step, I don't see any other way to unbrick the phone...
Thanks in advance

http://forum.xda-developers.com/zenfone2/general/guide-brick-soft-hard-bricked-zenfone-2-t3284256 be lucky your phone is recognized

Hello,
Frist, thank you for your answer. I had already tried this way but nothing. Finally, I fixed the problems (detect phone and unbrick phone).
1-In TWRP, I loaded recovery.img, boot.img and droidboot.img. Reboot in recovery mod, but I had the dead droid... so I pushed on power and volume up till I have a new screen.
2-In this part, I did a Wipe/Factory reset (useless I think), reboot in recovery mode (still dead droid). This time I selected the line "update with adb" (with an ASUS firmware). Then I had a message who told me update adb sideload. I did it and it installed the firmware. The smartphone reboot correctly.
Now, I have the same problem I had yesterday. In TWRP, my external storage isn't detected...

you use stock recovery or custom recovery, if you use stock recovery external-storage won't detected

Hello,
Thank you Bar4, I explained above how I fixed my problems. Now I'm searching a way to make TWRP (TWRP 3.0) detect my external storage to install Cyanogenmod 13.0. If it's really not possible, I would try with CWM (I have seen it in your screen).
Edit : I guess custom, TWRP. It's why I don't understand why it doesn't allow me to mount SD card or doesn't detect this same SD Card.

i use twrp 3.0 too, but external sd detected. no need to put on external storage, you can flash Cm 13 through internal storage
if you want to install custom rom it's better if you make a backup first, so if happen you failed when installing new rom or maybe you don't like it (new rom) you can go back to stock rom through TWRP restore

Ok, failed again...

Try a different rom or redownload the rom it might have been a bad download.
The error message says there is no updater script in the zip meaning it can't install anything as the updater script tells what directories to install the files if I seen it correctly that is.

maybe the CM 13 zip file you have download corrupted, try to re-download and re-flash it again. if still failed try another rom
( i'm using AICP Rom "based on CM 13 too") try it, it's awesome Rom ---> do clean install wipe all except internal storage and external storage

Hi,
Sorry for this late answer. As I failed to install those roms (CM13, Bliss), I'm going to stop here and wait for the Marsmallow update. But I'm happy my phone isn't brik anymore.
Thank you all.

Oneplus 3 do not boot after installing OxygenOS 4.0.2

Hello everyone!
My oneplus3 is actually running no OS and I'm having a boot loop.
I will try to explain what happened to me with the most details I can.
Before I ****ed everything up, I think I was running OxygenOS 3.28, not really sure about it but im 100% sure it was below 4.0, and it was rooted with TWRP 3.0.2 installed.
1) Today I had a pop up saying OxygenOS 4.0.2 was available (the official one that pops on the screen on boot) "Yay so coooool Nougat!"
1.1) I downloaded it, 1.4Go, then I pressed install
1.2) TWRP showed up, I didn't know what to do and that's where I ****ed up, I set my phone "factory new" in TWRP.
1.3) Phone restarted fresh new, I thought I had 4.0.2 but naaaaah would've been too easy so the official pop up showed again, I was still 3.28 I think.
1.4) Downloaded it once more, TWRP opened again, this time i was looking for the update i just downloaded in the "install" section. I browsed for quite a while and couldn't find it.
1.5) Master ****-up here: I tried to restore a backup. Then the bootloop happened. The black screen with "Oneplus" written in white. I was able to go back in TWRP by pressing power + volume down
1.6) Tried every kind of restore unsuccessfully, and tried ADB but it wouldn't load. Also TWRP said that I was running no OS when I wanted to turn off my phone for example.
2) I downloaded 4.0.2 from one plus website on my mac, and i flashed the official recovery instead of TWRP.
2.1) Transferred the update from my mac to my PC (seems important to me) and installed ADB & everything on both PC/O+3.
2.2) so adb worked in forceboot, i've been able to flash official recovery, tried once more to wipe & everything, but clearly I have no OS now, as TWRP said.
2.3) so i had the update in a folder (not a zip, probably due to the download being done from a mac), I made it a .ZIP with winrar, but "adb sideload update.zip" crashed at 0% everytime
2.4) looked at the archive then i noticed it was first a folder "OnePlus3Oxygen_16_OTA_039_all_1701140133_03b794d8a8b44883" then inside it i had the content like "boot.img" & everything. So i zipped it again but without that first folder because I thought it was the problem, but it kept on crashing 0%.
2.5) restarted my PC, looked on several forums, but i couldn't find any fix. Now adb can't even open update.zip anymore, it fails even before 0%.. I tried naming it .zip.zip, keeping the name "OnePlus3Oxygen_16_OTA_039_all_1701140133_03b794d8a8b44883.zip", using a third party app to allow more RAM to the cmd app...
I've been trying hard for 4 hours but I still have a O+3 without any OS... My last idea is downloading "OnePlus3Oxygen_16_OTA_039_all_1701140133_03b794d8a8b44883.zip" from my PC so it downloads it directly .zip unlike on my mac...
I hope I said everything, sorry for the long post but i'm desperate.. thanks for your attention,
Valentin

Thank you for answering! unfortunately i've already tried that and my problem occurs when i try to sideload the update from adb recovery... "couldn't load 'update.zip'"
I dont really know what to do now because I think my only option here is to load the OS through adb as I can't boot my phone to get the update zip inside a specified folder to load it from internal storage.

Try to install the new official TWRP version i think it is 3.0.3-0 through fastboot. Boot up TWRP, wipe every partiton and copy the update.zip onto the phone. You can copy it by connecting it normaly via USB(like you would do in OOS) and install the zip file afterwards.

install stock recovery and then try installing official OS. Or install modded twrp 3.0.2-1.28 and then try installing Freedom OS 2.3 via sideload or through internal storage.

Stop fiddling with the ROM. Download the ROM afresh directly to your Windows PC/laptop. Check the md5. Then start experimenting with the other suggestions but don't again meddle with the ROM!

I read your post again and here are a few things:
* Don't update Stock OOS via "System updates" in Settings if you are rooted and have TWRP
* Back up your data before updating, wiping or doing something with your phone.
* For the ADB error, see the FAQ #17 in the guide I provided.
Now, try this:
Flash TWRP via fastboot > boot to TWRP > connect your phone to your PC and copy the full Stock OOS v4.0.2 OTA to your phone > reboot to fastboot and flash Stock Recovery.
It didn't touch the internal storage. So, try to install from internal storage when you are in Stock Recovery.
Let me know if it worked.

[SOLVED] TWRP doesn’t let browse /sdcard files

I am having a problem it happened after I finally got to flash latest CosmicOS and set up a new password on my OP3. So, here’s what basically happened;
Once I got it up and running I noticed that home button and fingerprint sensor was completely disabled, then I tried to set up a new password (completely same password I used to decrypt my storage in TWRP 3.0.2-0) and fingerprint just in case but it didn’t react to me calibrating the fingerprint so I was like, ”alright, gladly I got a backup in TWRP”.
Once I rebooted to recovery it asked for a password as usually, once I typed that exact same password as before it just said wrong password, I tried it twice in case if I made a typo but still invalid password. And then I was panicing and pressed cancel and just rebooted back to OS.
I then removed all passwords there and booted back to recovery again, TWRP doesn’t ask for a password anymore but there’s a slider which says allow modifications or something similar and also there’s read only mode. When I slided the modification thing it just doesn’t show any of my files in sdcard folder when I go to ’Install’ tab but (0mb) instead. I even was able to browse and add files from my pc while phone was plugged in and in recovery mode, not anymore though.
Can anyone give me advice or help to get my oneplus 3 back in use? I have all the important files moved to my pc so I don’t mind losing files I have left in internal storage that much. Not if it’s necessary or easier workaround. thanks for reading this long-ass text :fingers-crossed:
EDIT: Issue SOLVED thanks to @AkR2014. I switched data partition from EXT4 to F2FS and then one more time back to EXT4 in TWRP's Wipe tab. (I was using latest blue_spark's TWRP-3.2.1-x version) and I was able to wipe data, system and both caches afterwards. After that I managed to flash new rom via USB-C to A with mounted USB flash drive on the other end and you know rest of the story. Do note that it WILL clear your internal storage so back up all the necessary files you need. And if you want to stay on F2FS data partition be sure to flash a ROM which supports it
EDIT2: There might be another way to mount your storage in TWRP but this is probably fail-proof method and worked for me

Oh and I couldn’t flash the Gapps in recovery after flashing the CosmicOs and nor I can’t now because of this haha. I can use my email though and send files through it from my another email if that helps

Wait, I think I found it. But the question is can and do I need to update the latest eng.stk’s TWRP through fastboot? And if so, is there instructions topic somewhere?

So here's the latest update: I flashed twrp-3.1.1-2 via fastboot but once I go to recovery it still doesn't let me browse files in /sdcard and if I put new password in OS it doesn't match in TWRP. I have a OS where I can boot to but no Gapps installed.
People say formatting data in TWRP would work, I'm just scared if that doesn't work and won't let me boot to OS anymore (even though I have a TWRP back up which I made before wiping my OxygenOS system data and caches in my pc as well in my phone's storage atm) and I can't flash anything in recovery mode, is there anything I could do? I'm in desperate need of help right now.
In this CosmicOS i am using Android 8.1.0 and I'm afraid something isn't supporting it or so.

As I said, flash eng.stk's TWRP. Simply flash the image to Recovery partition using the TWRP you already have. After that, wipe everything and clean flash the ROM. If anything goes wrong, you can use the Mega Unbrick guide method 2.

Thanks for the reply and link. I understood most of the parts except flashing the image to Recovery partition. Am I supposed to find the eng.stk’s TWRP from my Install tab in my current TWRP? Because it doesn’t show any files there. Also do I download the latest 3.2.1-x TWRP from the link you provided?

You will find TWRP 3.2.1-x v8.61 in the link I provided. Download that to your phone and save it. Restart your phone in recovery mode and in the current TWRP that you have, click the 'Install' button. By default, you will be shown zip files,if any. TWRP comes as an img file. So click the 'show img files' button at bottom right in TWRP and navigate to where you saved it and select it. Slide the bottom bar to install, you will be asked where to install it to. Select 'Recovery' and again slide the bar. It will be installed. To confirm, restart in recovery mode and check the version number of TWRP.
eng.stk's TWRP is compatible with OOS and custom ROMS. The offficial one doesn't work with some custom ROMs.

he is unable to mount storage via twrp , i have the sol but it will format your whole data / internal storage if your wiling to .
1 ) Go to twrp
2 ) wipe - > Advance wipe > change system file partation
3) if your on F2FS change to ext 4 or vice versa .
4 ) you will be able to mount sdcard
and dont flash this rom again , faceed same issue while flashing some oreo rom .
P.S : do it at your own risk .

Thanks man :highfive: I have really nothing to lose anyways so I gotta try that lol. How can I know whether I am on F2FS or EXT 4 though? And once it’s done can I access to my phone storage while it’s in recovery mode and just paste new rom to internal storage? Or do I need to push the rom via adb while in fastboot mode? Thinking to try out Paranoid rom which is based on Nougat, right?

Thanks for clarification tnsmani, appreciate the time you put into it. But as the person who replied to your text, I cannot mount the storage in TWRP which would prevent me of flashing pretty much anything on phone in TWRP.

If you are able to boot into fastboot mode, you can install TWRP through ADB.
But you can not copy, paste in TWRP.

Great to hear that. Though I don’t have Gapps installed. Accidentally tried to flash the wrong one before the mounting problem occurred and now you know rest of the story :laugh:
I’ll try to find another way to check it though. Oh and as well as the ROM

Wiped System/No OS installed, Error 7 while installing OS

Hello guys,
Today i accidentaly wiped everything through twrp...
Now i dont have an OS. After trying to flash the new OS as zip file through twrp Im getting an Error 7 Message. I have already tried to wipe it all again and editing the update file in the google folder (which is the only fix i can find on Youtube) but it hasnt worked for me.
I have the latest version of twrp and i also downloaded the official ROM from the OnePlus website.
Hopefully someone knows a other fix than just editing the update file.
Thank you!

Go to fastboot.
Flash twrp 3.2.1.0 universal codeworks dumpling.
Make sure you have downloaded the correct OOS zip file to your pc.
Boot into twrp from fastboot by pressing volume key to chose recovery mode.
Just as a precaution chose format data, type 'yes' and press enter.
In twrp, allow MTP.
Transfer the zip to phone.
Flash it.
Done.
I also faced the same problem once and this helped me. If you still have any problem contact me.
