[Q] Nexus 7 (2013) Stuck between TWRP 2.6.0.0 and Google logo

Hello everyone,
I hope there is somebody out there who can help my Nexus7 -2013 to operate again.
My nightmare started after upgrading Android os to 5.0.2. The tablet started to shutdown from time to time, so i searched for downgrading to an older version but could not find such option on the menu.
Therefore, i followed a youtube video -not knowing what i was doing- and setup TWRP 2.6..0.0 on my tablet. When i opened it again, OS was working but google play and keyboard were not working.
So, i tried to backup, no success. Then i tried all options on TWRP menu (wipe, factory reset etc.) and it got worse.
Currently, when i open the tablet, it takes me to Google logo with a lock, no desktop or OS works. (see picture 1). If i wait long, it takes me to TWRP menu. see pic2)
For the last one week, i tried everything; adb sideload, install, mount etc, nothing solves the problem.
There is no place to run flash commands etc. I connected to computer but only adb sideload works and it does not help me use any other commands.
I had a flash disk with 5.0.2 and 5.0.1 factory images, but it did not setup those two files (and does not see them on flashdisk anymore i do not know why)
I also downloaded twrp 2.6.0.0 and 2.8.5.0 MD5 img's and tried to use but no success, changed file extensions to zip also not worked etc. (see pic3)
Anyway, finally i downloaded alternate rom (CleanROM-5.1.0) and UPDATE-SuperSU-v2.46.
I am trying to setup any of these, just to operate the device.
I install SuperSU (zip1) and CleanRom(zip2) together from install menu and setup was complete (see pic4). CleanRom was setup successfully.
However, when i reboot from TWRP after install it says "root permission appear to be lost..." (see pic4). Whatwer i do, it opens with Google logo and the only place it takes me back is TWRP recovery page.
Your support on this is greatly appreciated.
Thank you

Follow the instructions here. You can transfer installation files in recovery using adb commands or you should be able to copy using Windows Explorer.

Or go back to stock using the Nexus images.

[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.

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 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.

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.

Can't find my way through the many guides, could use a lil'bit of help

Hey lads!
I am trying to root my HTC One M8, so I can get a finer options for sounds (and other advantages, aswell). I found this post https://forum.xda-developers.com/htc-one-m8/help/how-to-root-htc-one-m8-android-6-0-t3420748 about rooting an M8 with android 6.0. I'm writing this post, because I don't want to screw it up, so it seemed better to ask for help, before I do something stupid and brick my phone. I tried searching the forum, but after opening like 10 tabs, I lost my way. (I am using Windows 10, legit)
So, this is what I did:
1) Downloaded the Android Studio.
2) Via the studio, I downloaded the 6.0 platform.
3) And here is my first block: tried to install ADB, via Universal Naked Driver: I downloaded the ZIP, unpacked it, and while my phone was connected, tried to update its driver via the Device Manager. I got a message that it's up to date, and even tho I picked the 'I have disk' option, it wouldn't do anything. Now, I downloaded MiniADB v_1031, and when I ran the cmd from here, I could see my device with adb devicelist. I also installed HTC Sync, and used the driver installer from adbdriver.com, and it showed that I have the needed driver.
4) From the folder where I have unpacked miniadb, was able to run adb devicelist, and adb bootloader reboot aswell. But from that point, even tho I enabled developer options in my phone, and USB debugging aswell, my PC can't see the phone, only if I reboot to normal mode. When I am in fastboot USB, adb devices just says 'list of devices' and a blank line under it.
5) Tried to unlock the bootloader, and I got my identifier token. I am good to go then, I have every driver what I need for continuing from here?
5)b) Edit: Seems like I managed to unlock the bootloader.
---------
So if I understand it well:
From now on:
---------
6) Download the EU version of TWRP 3.0 from here (I am from the EU)
7) Use the cmd 'fastboot flash recovery twrp.img'
8) The site mention a key-combo to prevent the phone to go back to basic recovery, do I need this?
9) Do a backup via TWRP (is it going to be a simple option in the recovery? How big SD card do I need? Atm, I have 12 Gb one, gonna buy a 128 one in like 1-2 month)
10) Copy the SU.zip to my SD card and use a flash option in the recovery?
Sorry for any dumb question, I'm kinda scared bricking my phone, but at the same time, I would like to get the advantages of rooting.
So anyway, did I miss out on any step, screwed up anywhere, or smth like this?
Any help is much appreciated!

My comments to your steps/questions:
4 and 5) adb and fastboot are two different, but related interfaces. Don't feel bad, it's a common mistake to mix up the two (adb and fastboot). You'll really only need fastboot for rooting the phone. The step to "adb reboot bootloader" in the TWRP install instructions can alternately be done without that command, using the button combo to get to bootloader. But I think you must have figured that out by now, if you managed to unlock the bootloader.
In summary,
adb: needs USB debugging on in phone settings, only works when phone is booted in OS or alternately when booted into TWRP (last part obviously doesn't help, if you haven't installed TWRP yet).
fastboot: only works in bootloader-fastboot mode (will not work in OS or TWRP), does not need USB debugging on in phone settings.
6) The options are for download mirror locations (US vs. Europe - literally just where the download's server location is located), and do not specifically refer to different TWRP versions. The same TWRP version works for both US and Euro M8 models. What you downloaded is fine, so my comment is just FYI.
8) No, you shouldn't need this. I believe this comment refers to newer devices, and not specifically to the M8. I literally think the TWRP team has copy/pasted this statement to instructions for every device on their website, whether it applies or not.
9) Yes, this is a clear option once booted into TWRP recovery. Literally, on the TWRP main screen, you will see a big button labeled BACKUP. Tap it, and select system (ROM or OS) and boot.img, and also backup data if you like. The backup of system and boot.img will take around 2 GB. The backup of your user data might be much more, depending on your apps, etc. Although, if you just unlocked the bootloader, the phone should have been wiped, so you may not have much (if any) user data to backup.
10) While SuperSU 2.76 (mentioned in the thread you linked) should work fine, I would suggest using the latest stable version 2.79 from here: https://forum.xda-developers.com/apps/supersu/stable-2016-09-01supersu-v2-78-release-t3452703
Just put it on the phone, boot into TWRP, select INSTALL, select SuperSU 2.79.

Don't worry, you won't brick the phone (permanent damage) by unlocking the bootloader, custom recovery, root, etc.
Anything you do is recoverable/reversible, even if something goes wrong (especially if you make a TWRP backup of your current stock ROM before rooting).

device keeps rebooting to twrp

Guys,
My father got my op5t with root, I think he had oreo oxygen os rom, after a couple months, he entered twrp by accident and he whiped, he did not know what he was doing. Long story short, the device keeps rebooting to twrp bluespark 3.2.1 v8.78. When the device is in twrp, i tried to connect to the pc but it wont detect the device.
My question; how can I fix this, I downloaded (OnePlus5TOxygen_43_OTA_034_all_1804201221_5c1b6d44ac9) but I dont know how to put in the device in order to install the zip file through twrp to restore Oxygen Os.

Hold the power+volume down buttons together and don't let go until you reach the twrp load up menu.
Stick the zip file into a storage format that hooks up to the USB-C, go into twrp and switch from internal storage to USB OTG and flash it from there.
I'm not too sure about this next method but you may be able to hook your phone up to the computer and have it on TWRP, you might have to look for the setting in the menus, then find the phone from your PC and drag the file onto the phone. I assume you know the steps in how to flash a new ROM.
Just a reminder, you'll have to be on , 5.1.7 Oreo to make the jump to 9.0 pie oxygen OS. Do you know what version he was on? You might have to just go into download mode and use ADB to flash the file.

thnx for response, but I said from the start that I believe that he was running oreo, im sure he was not on pie, it could be oreo or nougat but I think oreo. USB otg does not work for me, otherwise I would have tried that, I dont have the equipment.
The other method you mentioned about adb, If I go to twrp, click on advaned then you can click adb sideload, from there you should swipe to start sideload I believe, then open cmd in winodws and type ''adb sideload'' then drag the zip file to cmd and hit enter, however it says; cannot read 'E:\op5t restore stock\OnePlus5TOxygen_43_OTA_034_all_1804201221_5c1b6d44ac9.zip
How should I proceed ?

hold on, I found an option to enable mtp in twrp, now the pc finds the device, let me put the stock rom 5..1.1 that I downloaded and report back how it goes.

after flashing te the stock zip file, the devicr was in bootloop, then I figured I had to uninstal Magisk with the magisk uninstal zip file, after that the device booted fine.
thnx for the help anyways, really appreciated it ^^
