EOS4 won't install on my tf101

Hi there,
A few weeks ago I rooted my tf101 and installed clockworkmod 5. Installing the rom from Raymanfx isn't a problem, but it doesn't run very smoothly. So I wanted to try the ROM of EOS4. Installed both nightly's .93 and .92, but both don't work. I've wiped the cache, but it still stays stuck in bootscreen. I'm wondering, how can I find out the problem and how can I solve it?
Thx in advance!
Yours sincerely,
Anderverhaal

Any time you flash a different ROM (from a different DEV), for best results you should wipe:
Cache
Davlik Cache
System (ROM)
Factory Reset (will not wipe the /data/media/ aka /sdcard/ directory, just the apps installed in the /data/ directory).
Failing to do a factory reset, there may be some system settings from your previous ROM that are still lingering and causing issues with the TeamEOS 4.
Also, I would HIGHLY recommend using TWRP 2.3.2.3 for EOS 4. The new multi-user file structure does not work well with CWM 5.X.
If you want to update, you can boot to CWM, connect to your tablet via ADB, push the latest TWRP blob and use the ADB shell command to dd it to the recovery partition.
Otherwise, install a ROM that boots, then install GooManager and then choose the Install OpenRecovery Script.

Installing CM11.M11 on Nexus 5

Hi,
I'm about to install CM11 (cm-11-20141008-SNAPSHOT-M11-hammerhead.zip) on my Nexus 5, but wanted to be sure I'm not about do something obviously stupid. I tried using the CM Installer, but it said 'firmware not supported'.
I have
- Minimal experience.
- LG Nexus 5, hammerhead
- unlocked and rooted. (it did a factory reset on unlocking)
- Fresh Android 5.1.1 with bootloader version HHZ12h.
- TWRP 2.8.7.1 (took a backup and copied the whole TWRP folder to my laptop), flashed manually using fastboot flash recovery twrp.img.
- Latest TWRP manager installed from Play Store.
- standalone adb and fastboot installed on my Windows 7 laptop. No SDK. 'adb devices' lists the phone when connected.
- cm-11-20141008-SNAPSHOT-M11-hammerhead.zip downloaded to my phone under /sdcard/.
- cm-11-20141008-SNAPSHOT-M11-hammerhead.zip is also present in same folder as adb.exe and fastboot.exe.
Questions are:
- Hope this build of CM is compatible with my Nexus 5 & the bootloader version and whatever else there might be compatibility issues.
- How should I do this: According to "official CM installation on Nexus 5 guide" on wiki.cyanogenmod.org it seems like I'm supposed to push the zip file to /sdcard/0, but /sdcard seems to be a link to /sdcard/emulated/legacy, which contains no folder named '0'. Should I create it and put it there?
If you're coming from a ROM with Android 4.2 or newer to CyanogenMod 10.1 or newer: adb push update.zip /sdcard/0/

OR
Given that "cm-11-20141008-SNAPSHOT-M11-hammerhead.zip downloaded to my phone under /sdcard/", can I just: boot to recovery, click on Install, select the zip file and swipe to flash?
Finally a general query: Is there any reason I have to connect the phone to my laptop and run any adb, fastboot commands except to transfer the zip file from laptop to phone and to boot into bootloader or recovery with fastboot command? I already have TWRP running.
Thanks
Kashyap

Edit - before you flash, create a backup in twrp, including your efs, and copy it to your laptop for peace of mind.
I don't use cm, but that sounds like the right file. It doesn't matter which location the zip file is on your sdcard as far as I know, I think they've just said /sdcard/0 to make it easy to find from within twrp. Sounds to me like you've covered all your bases, nice to see someone manually flashing a nexus as a start. I'd go ahead and flash the zip, don't forget to factory reset if you're coming from stock. Also, you may want to find a gapps package if you haven't already. Since you seem to have taught yourself the right way, and your PC is setup for fastboot already, it should be easy to flash back to stock/restore under twrp. You don't even need adb to push files to your phone, you can just download them straight to the device. I generally only use my PC for fastboot flashing to stock,or transferring large amounts of data. Good luck, enjoy your nexus - first boot will generally take just long enough that you'll start wondering if its broken.

Thanks for the quick response.

Just curious why?
If i do a factory reset, will it not delete /sdcard/cm-11-20141008-SNAPSHOT-M11-hammerhead.zip? Do I just copy it from laptop to phone after reset and proceed to flashing? Or there is some way to not wipe 'sdcard' during factory reset?

I did do a TWRP backup, but selected what to backup in the TWRP manager app, there is no option called EFS. Anyway, I'm creating a new using the recovery UI, where there is a check box called EFS. Thanks!

Didn't know there was any other more automated option/way. , is there? Only thing I knew was the CM Installer, which said the firmware isn't supported. .

Yes, I was planning to, but taking it step at a time. .
I was planning to get gapps-kk-20140606-signed.zip from cyanogenmod.org, but lets see. I'll probably post another question here asking which is the compatible one.

Factory reset just wipes data/cache/dalvik, it should leave your sdcard storage intact. Just out of interest,why cm11? KitKat is pretty long in the tooth, and I've always found aosp based ROMs to perform better than cm on nexus 5. The problem with having no gapps will be no access to play store/google account services, so you'll have to get apps from less trustworthy sources.

Worked
Thanks.
It worked fine. Though it was totally useless without either the play store or basic CM apps. Couple of notes:
- After wipe/factory-reset (from TWRP Recovery UI) /sdcard was untouched.
- Installed the ROM using TWRP Recovery UI -> Install -> Select the zip file from /sdcard and swipe.
- CM Installer on Windows 7 laptop worked fine once the CM was installed. But it downgraded the build from Nov to Aug-2014.
- Also CM Installer removed my TWRP and replaced it with CWM. Not happy.
So actually all that's needed is:
- Unlock the bootloader and root.
- Install TWRP Manager
- Try to use the TWRP Manager's "Install TWRP" to install the TWRP Custom Recovery. If that doesn't work then do it manually. Download twrp.img
- Install ADB and fastboot, you don't need the whole 1GB Android SDK. Just search for "ADB Fastboot without SDK".​- Enable USB debug, connect the phone and ensure that 'adb.exe devices' prints a device.​- fastboot flash recovery twrp.img​- Download the ROM zip file you wanna install on the phone itself, no need to involve the laptop.
- Boot into recovery (e.g. using TWRP Manager -> Reboot options) and do what I did above.
Once you've installed Cyanogenmod, DO NOT use CM Installer. This is written in July'2015. May be things would improve in future.

Gapps installation problem - LineageOS 16 + Oneplus 7 Pro

I'm trying to install the OpenGapps package for LineageOS 16 on my new Oneplus 7 Pro, but have a problem installing it.
First I tried the "open_gapps-arm64-9.0-micro-20190827.zip" package, but it told me its the wrong platform. Is it not arm64?
Second I tried to install the "open_gapps-arm-9.0-micro-20190827.zip", but gives me an error 70, saying I do not have enough space.
Maybe someone have a solution for this?
Thanks

Try MindtheGapps. I've seen this work for some.

Tried it. Still does not work.
I got it semi, but still not working. Seems like the problem is within the way the partitions getting handled. My old Oneplus 5t had a boot, recovery, system partitions. The new one includes the recovery inside the boot it seems instead.
Here's how far I am now:
1) Unlocked the phone
2) Installed TWRP
3) Install Lineage ( This overwrites the TWRP so you have to install it again )
4) Reboot straight from TWRP after flashing the Lineage... back into the Bootloader/Fastboot mode and install the TWRP again.
5) Boot back into TWRP recovery and now I'm able to install OpenGapps ARM64 version.
But after this I cant boot the OS anymore...

Format data in twrp then try boot again should work

Still no luck. Tried many things now... but here's what happens:
1) Installing the TWRP
2) Format data partition and everything else
3) Reboot back into TWRP
4) Install Lineage ( At this point I'm able to boot into Lineage just fine )
5) Trying to install Open GApps at this point gives me:
Code:
# Begin Open GApps Install Log
------------------------------------------------------------------
------------------------------------------------------------------
# End Open GApps Install Log
INSTALLATION FAILURE: This Open GApps package cannot be installed on this
device's architecture. Please download the correct version for your device.
# Begin User's gapps-config
# End User's gapps-config
It says I need to install the ARM instead of ARM64...
But if I go back into the bootloader and flash the twrp and boot back into the recovery, I'm able to install Open GApps ARM64 just fine. Seems like a weird "device's architecture" detection problem in the Open Gapps or maybe it could be the TWRP... not sure...
Also after this it will no longer boot.
Kinda weird problem....

Don't wipe system afaik vendor LOS generates it's own, Also might be in the wrong slot make sure the slot changed when rebooting back to recovery to install gapps, I used MindTheGapps latest version from OP worked great.

Have not wiped the System and Vendor partition after I installed Lineage... It boots just fine... just not if I install Open GApps....
Tried MindTheGapps latest version, but still no luck.

Okay got it working. The problem was the A/B partition layout they have in this phone... Was not aware of this.
This article describes it pretty well: https://lineageos.org/Changelog-19/
So yeah this is what I did:
1) Boot into Bootloader/Fastboot mode
2) Flash the boot partition with fastboot flash boot twrp-3.3.1-52-guacamole-unified.img
3) Restart into TWRP - Format the data partition and clean the system partition etc.
3) Restart into recovery TWRP once more to get the data partition ready
4) Now you can transfer the lineage-16.0-20190827-nightly-guacamole-signed.zip over to memory.
5) Now flash the zip file and let it complete. This will overwrite the boot partition with TWRP and replace it with Lineage's own boot/recovery image.
6) Now reboot into Lineage's recovery. Now select Apply update > Apply from ADB and send the "MindTheGapps-9.0.0-arm64-20190615_031441.zip" file to the phone with "adb sideload MindTheGapps-9.0.0-arm64-20190615_031441.zip" - You might have to confirm the zip file....
After this is done, the phone should be ready for use.

I am facing the same A/B slot problem with my Moto Z2.
After setp 5), did you let the lineage OS fist then reboot into recovery, or did you go straight to the lineage recovery?

Thank you so much for this. I finally fot it sorted. I did find that sometimes you have to ubplug the USB cable and plug it in again to be recognised, but I got it going. Goodby Google!!!!
I am using Gentoo Linux with adb to do this.

Samsung devices (2) stuck in system boot splash

HI,
I have 2 Samsung devices with TWRP installed, and I can access the TWRP recovery menu. When I install the flash ROM and try to boot, devices are stuck in system boot forever.
Device 1: SM-T800, with LineageOS 14.1 previously. I opened an email and the device got hacked, so I did a factory reset (which failed), then re-flashed the latest TWRP and recovered rescue mode. Now when I flash the Lineage ROM (from TWRP) the device does not boot to system but keeps showing the splash screen. I think the hack might have placed immutable files under system. could I format this partition to zero it out via ADB? What other choices are there?
<EDITED>
Device 2: Galaxy S3 GT-I9300 - I solved this so i removed this section.
Thank you for any help.

Device 2: Galaxy S3 GT-I9300, with working TWRP. This device is giving a "Failed to mount /efs (Invalid argument)" error. The previous setup was shared storage with sdcard and encryption on both internal and sdcard. The sdcard got corrupted, hence the error. This post suggests running
Code:
dd if=/dev/zero of=/dev/block/bootdevice/by-name/modemst1
but the device does not have identifiable boot device under /dev/block. I think this might work if I can identify the boot partition name?
Thank you for any help.

Flash a custom ROM for i9300 via TWRP. Download a custom ROM for i9300 and the appropriate Gapps to go with the ROM, store them on external sdcard. When you are in TWRP, before you flash your ROM, select the "Wipe" option, then select "advanced wipes", on the next menu, choose the system partition, data partition, cache partition and dalvik cache partition then swipe the slider to wipe. Then go back to home screen in TWRP and choose the "Install" option, then choose your ROM file and your Gapps file then swipe to flash. When the flash is finished, select the "Reboot system" option and see if it boots into system.
If that doesn't work, we will take some steps further back and try starting from the beginning.
Keep in mind that some of the custom ROMs for i9300 may have a different partition structure and partition sizes than the stock firmware for i9300 has and may require resizing certain partitions such as the system partition by flashing a custom PIT file like the Galaxy S2 had to do before it flashed certain custom ROMs.

Hi, thanks for the input.
* I had already solved the GT-I9300 issue before your post (I should have added to thread rather than edit the original post). I solved issue with that device by including system partition in the wipe.
* For the SM-T800, I used a LineageOS-14.1 that I had stored somewhere. That also did not work, until I only flashed Lineage and did not include any GApps. If I really need it, I can always flash later. I assume the latest GApps 7.1 build conflicts with older ROMs.
An unexpected problem was the lack of current ROMs for the 2 devices. SM-T800 has nothing other than last build Lineage-14-1-20190205. The I9300 has several unofficial ROMs floating around for newer Android versions, but they are all debug/dev builds with enabled options that drain the battery very quickly.
If anyone comes across a decent ROM for either of these devices please LMK. Thanks.

how to flash any custom ROM for your device.

Hi there
NOTE: please follow this steps one by one.
Disclaimer: i am not responsible if your device got bricked, i use this method for my samsung galaxy A20e and it works.​
well when i wanted to flash a custom rom for the first time, i didn't find any steps to follow, i just picked out the rom then flash it via twrp and rebooted and that was a big mistake, the rom booted but i wasn't able to do anything, so today you will see the right way to flash .
First of all, you need to have twrp installed.
then download the rom version that you want for example, i used this rom for my device: https://sourceforge.net/projects/derpfest/files/a20e/
next put the file that you have downloaded in an sdcard.
then reboot to recovery, you can do it by powering off your phone then hold the volume up and power keys until you see twrp's logo.
click wipe option, the advanced, after that check all the partitions there except sdcard and usb-otg (and vendor if it is not included), for my device i wiped system, vendor, data, cache, dalvik and cache, but it may be different for you, now swipe to the right to confirm wiping.
when the wiping process has been finished, exit advanced wipe and choose format data, you will be asked if you are sure, type yes.
go back to the main twrp window, then select flash, click select storage and choose sdcard(or usb-otg if you are using it), then you will see the zip file and install it.
reboot and that's it !! it is depending on your phone's speed now, just be patience.
enjoy your time in that rom, cause you will change it soon *__*.
