[Q] 2.3.4 update failure leads to whole crash..

Ok, so Was using my nexus s today and I kept getting the notification to perform a system update to the newest version of gingerbread (2.3.4). Prior to pressing update my phone was at 2.3.1 default with 2.5.### ClockworkRecovery and it was rooted. Everything worked on it perfect. So I proceeded to download and install the update, and CWR fails to install the update and I would have to take out the battery to restart the phone. I had been doing this multiple times and I wanted to get it updated. So I go into CWR and try installing it manually:
I look around and try to find the file and I couldn't, I reset user data to see if it would fix it and it didn't, then I go back and start formatting the following folders, /system, /cache, /data and one other but I did not format /boot, so Then (noob me) I restart to phone and of course the rom is gone. I get back to recovery and try to restore from update.zip but the console said the file could not be found, I look up my model and look for a full verison rom and the mount my usb storage and place the rom .zip on the storage and try to install from .zip on sd but it did not work so I end up grabbing this and installing it and now I'm stuck, when I do adb shell it doesn't pick up the phone any more, it can fast boot on the phone but it can't go into recovery and I have no idea what I should do to try to fix this problem.
NOTE: before I ened up installing and replacing the recovery, my /system folder would not mount due to "invalid arguments"
Model is i9020T
I don't have firmware version access
and if there is any other information I can provide please let me know
Update:
I got the device to be recognized by fastboot but not by "adb shell", when I type adb shell no device is found, so I guess my question now is do I need to just flash a new recovery and then try to flash a new rom?
Solution:
1. fastboot your phone, (volume up+lock/power button)
2. place the recovery image you want to install in the "Android SDK"/tools/ folder
3. in your cmd/terminal, while in "Android SDK"/tools/ execute:
Code:
fastboot flash recovery "NAME-OF-RECOVERY.img"
4. once that is installed and it should work, then restart your recovery mode
5.clear all your data/factory reset, including davlik cache
6.mount your sd to your computer so you can place the Rom you want on your phone's sd
7. In recovery choose zip from sdcard to install.
8. It should install, if it gives you problems try another rom, I had problems with rAv 1.2.2, keep restarting every minute. I used "NS-2.3.4-GRJ22-Stock-Deodexed-signed.zip" and it worked.
9. Restart the phone and be patient the phone will start up and you should be set.
Hope this helps someone!

[Q] LG Optimus one (p500) - upgrade it to Android 4.4.2 KitKat problem

Hi,
Hope this is the right place to ask...
I have LG Optimus one (p500) and I tried to upgrade it to Android 4.4.2 KitKat CM11 ROM.
I used this guide:
http://www.ninjaromeo.com/update-lg-optimus-one-kitkat/
But since the link to the rom is down - I tried it with mukulsoni cm-11-P500-Ver10.zip rom from here:
http://forum.xda-developers.com/showpost.php?p=51341582&postcount=1154
I'm not sure is it's relevant - but in the ninjaromeo guide it was stated to:
Do the following: “Wipe Data/Factory Reset > Yes”
Do the following: “Wipe Data/Factory Reset > Yes”
Do the following: “Advanced > Wipe Dalvik Cache > Yes”
Do the following: “Mounts and Storage > Format /system > Yes”
but in mukulsoni guide is was stated:
DON'T WIPE ANYTHING (data/factory reset + wipe cache partition+wipe dalvik+ format system)
but since I used ninjaromeo guide I did the wipe as instructed....
anyway - the installation finished o.k. and the device rebooted and i got this message:
Fastboot mode started
udc_start()
--suspend--
--reset--
--portchange--
--reset--
--portchange--
stall get_descriptor 128 6 1006 0 18
fastboot: processing commands
the phone was discovered by my windows - and some drivers ware installed.
after long long wait i disconnected the the phone from my computer and re connected it back, I got this message:
--suspend--
--suspend--
--reset--
ep1/out fail nfo=40 pgo=74000
--portchange--
usb_read() transaction failed
--reset--
--portchange--
fastbootops!
fastboot: processing commands
but nothing happen.
I tried to re install the rom - this time without the wipe part (though I guess it is too late since I already did it the first time) - and again I got to this message:
Fastboot mode started
udc_start()
--suspend--
--reset--
--portchange--
--reset--
--portchange--
fastboot: processing commands
should it take so long to complete - or is it because something I did wrong?
what should I do now?
Thanks!
=======================================

then I have Installed ClockWorkMod through ADB:
http://forum.xda-developers.com/showthread.php?t=852905
then installed again the new rom from mukulsoni cm-11-P500-Ver10.zip rom from here:
http://forum.xda-developers.com/showthread.php?t=2589303
so now the phone is restarting - but a get:
"unfortunately, google play service has stopped"
and then:
"unfortunately,the process android.process.acore has stopped."
and:
"unfortunately,kitkat launcher + has stopped"
after that the phone reached the wallpaper with the lock etc - but after few seconds the phone reboot over and over again....
any idea?
Thanks.
=======================================
o.k.
did recovery and then "wipe data / factory reset."
got:
"formatting /data
formatting /cache
formatting / sd-ext
formatting /storage/sdcard0/.android_secure
data wipe complete"
then reboot system now. - and the phone work without a problem (almost) -
now i get no signal (although the sim and network were o.k. on the previous rom).
when dialing a number i get:
"mobile network not available."
in: settings->more->mobile networks->network operators-> choose automatically
I get error: "can't connect to this network right now . try again later"
in "search networks " I get error "error while searching for networks"
i'm trying to update to 10.3 via OTA - will it help?
any idea?
Thanks.
===========================================
so the problem was with the baseband.
i used this to installed a new baseband :
http://forum.xda-developers.com/showpost.php?p=15250036&postcount=1
and then re install the new rom all over again - now it's working fine!!
But there is a problem again...
Now i cant connect to the google play / add new account to the phone etc...
i get error:
"there was a problem communicating with google servers/ tray again later"
installing the Google Play Store 4.6.16 did not help - still the same error.
can you help??

Did you get updated to 10.3? are you still having this issue? I'm using this ROM without any of the issues you've described.

If you had posted this on the thread where you got the ROM from, your question would've been answered long time ago.

[Completed] Android Tablet Stuck in Bootloop

Good evening,
I have recently acquired a tablet and it is stuck on the logo screen. It is a Nuvision TM800A510L 8" HD IPS Tablet. According to the website it is supposed to run Android 4.4 kitkat.
Using the Power button and Volume up button, I can get into Droidboot. My options are:
-REBOOT DROIDBOOT
-REBOOT
-RECOVERY
-POWER OFF
At the bottom, it states it can't mount sda1, E:installer device ignored, E:No valid installer medium found, and Could not open /sys/devices/virtual/backlight.
I have selected RECOVERY and when that opens up I have the Red Triangle "No command" Droid. Top to bottom this is what I see:
Android system recovery <3e>
NUVISION_8_INTERNET_TABLET-userdebug 4.4.4 KTU84P user.20150120 release-keys
Volume up/down to move highlight;
power button to select.
-reboot system now
-apply update from ADB
-wipe data/factory reset
-wipe cache partition
---
When I try to use the wide data/factory reset option it erases all the data but that doesn't make my tablet bootable.
Does anyone know where I can find a ROM for this tablet? I have been looking everywhere for one. If not, any suggestions on a compatible custom ROM?
I would use the ADB sideloader but I don't know where to find a update file for this tablet.
Any help is greatly appreciated, thank you very much.

Magisk root > bootloop > Stock ROM > success

I have almost finished setting up new Redmi 6.
After rooting, getting TWRP on the phone I have reinstated all apps trough TitaniumBackup. I have reinstated too many apps from TB and at some point I have removed 1 or 2 apps too many that I thought are only from TB...
Inside TB I went into system apps and deleted apps wit: Backup copy [APK + backup]. Before I realised that apps with backup were actually original Xiaomi appswas too late, I had few warnings later and phone rebooted but couldn't boot into system.
This way I got rid of:
com.android.providers.telephony
com.android.phone
I could recreate what I have removed going into old phone and seeing which apps are backed up from system...
Can you help me to get apps back trough TWRP or FASTBOOT?
USB debugging was still on last time
My SD card is formatted as part of internal storage
TWRP File Manager can browse ROOT folder
It is newest ROM for Redmi6, [V10.3.6.0.OCGMIXM_], can someone provide copy of APKs please?
When in TWRP I mount system only, and try to [wipe dalvik] I get messages:
Failed to wipe dalvik
Updating partition details...
df /external_sd > /tmp/dfoutput.txt process ended with ERROR: 1
df /external_sd > /tmp/dfoutput.txt process ended with ERROR: 1
...done
Unable to mount storage
I almost will not loose any data, but:
if I can I'd like to move missing apps back to /app/data/ OR /system/app/ ? to recover system so it starts
if need be I will flash Xiaomi ROM and start from scratch but will loose many h of hard work on de-bloating etc [I hope that flashing original ROM will be easy since TWRP is working fine]
During TWRP - ADB sideload:
HTML:
adb install com.android.phone.apk
error: device '(null)' not found
- waiting for device -
What can I do???
-------------------------------------------------------------------------------------
Turns out I had to flash original stock
Xiaomi guide is terrible and out of date, so:
there are prerequisites required, like ADB, drivers, that is well explained on Xiaomi site, then...
download original stock for fastboot >>> unpack folder XXX sitting inside 2 archives [it's not zip] >>> download/install and run XiaoMiFlash.exe >>> SELECT button - navigate to unpacked folder XXX >>> attach mobile >>> refresh = device will appear on list >>> FLASH
Read official xiaomi instructions on flashing original ROM just in case something will get updated
Why not any other way?
In TWRP it asked me for a password at the start
I couldn't get /system/ or /data/ mounted, wiped or formatted.
I have seen folks giving advice on how to do it, but often it didn't make sense or it didn't work.
I would be risking bricking new device by other methods & I had no more than 3 pictures to loose on flashing ROM and hours spent on doing up.
Interesting is, there really wasn't even one working advice on how to mount i.e. /system in TWRP when password is missing in booted operating system [like my case, I couldn't find any info on that, all at some point were going to advice to do something that required mounted /system or /data]
But then I just finished whole process of flashing stock ROM; I have set [1. simple password] then [PIN], went to TWRP, tried to use OS password/PIN and it didn't work, it didn't remove encryption .
----------------------------------------------------------------------------------------------------------------------------------------------
Found a solution on how to root the phone after all above.
After another Original stock ROM 10.3.6.0.OCGMIXM flash with XiaoMiFlash.exe, phone will automatically restart and start OS
But... I didn't let it to boot
Once it restarted I have pressed Vol- [button down] and waited for fastboot to load [no need to hold power button]
Installed TWRP 3.0.0.0
Restarted
Hold Vol+ [button up]
TWRP loads
CANCEL if asks for password
----------------------
INSTALL boot.img [when you flash stock ROM it is inside folder, just copy it across]
in MOUNT tick /vendor & /system
use back button to exit MOUNT
INSTALL Magisk 19.3.zip
clean dalvik cache and swipe
I have once again restarted to RECOVERY/TWRP
------------------------
When OS booted I couldn't run/start Magisk APK/aplication. Screen blinked and that's all. Root not working.
download Magisk Manager [7.3.4 in my case] from web & install
I could start application this time & it asked me to install something extra - I have chosen to install it right away
Magisk reboots phone
Now phone was finally rooted
---------------------
I used external USB attached to phone with files so I didn't need to copy files to phone.
This is much more convenient as after restarting to TWRP first time there is nothing on the phone and you would have to sideload.
---------------------------
Below is LibreOffice doc with ADB commands to uninstall bloatware. In the column next to uninstalling commands, are commands to instal same app back [I do not know will this always work since I tried only on few] [some missing - you can create it yourself]
Potentially further down the list there are more necessary apps. Uninstalling them did not cause problems in my set up, but sometimes they might be needed for less important stuff...
https://www.dropbox.com/s/xpfeh4wx1nv5dlf/Bloatware removal + SD as internal.ods?dl=0

Bricked OP 7 Pro, MSM isn't working.

Following a guide to flash a custom ROM, I followed these steps after flashing TWRP:
- Go to main menu, then tap Wipe.
- Now tap Format Data and continue with the formatting process. This will remove encryption as well as delete all files stored on the internal storage.
- Return to the previous menu and tap Advanced Wipe.
- Select the Cache and System partitions to be wiped and then Swipe to Wipe.
- Sideload the /e/ .zip package:
- On the device, select “Advanced”, “ADB Sideload”, then swipe to begin sideload.
- On the host machine, sideload the package using: 'adb sideload filename.zip'
This process was unsuccessful, and now I am stuck in a bootloop, unable to access TWRP.
Tried the MSM tool but I get "Image does not match".
Not sure how to proceed. Any advice? I only have a few days to get this solved before I lose 300 bucks.
